Technical Field

The present invention relates to a latent heat storage building element including a latent heat storage material capable of adjusting a phase change temperature.

Background

In the prior art, various technologies for adjusting indoor temperature applied to building attics, floor materials, wall materials, and latent heat storage materials for interior decoration have been proposed. In the mid-latitude area, cooling is needed in winter and heating is needed in summer. The target temperature standard for regulating the indoor temperature is substantially constant during cooling and heating, and is preferably about 18 ℃ to 26 ℃ and more preferably between 20 ℃ and 24 ℃. In order to adjust the indoor temperature to the temperature range by the heat radiation and heat absorption of the heat storage material, a certain temperature difference is required between the room temperature and the heat storage material, the ideal heat storage temperature for refrigeration is lower than 20 ℃ to 24 ℃, and the ideal heat storage temperature for heating is higher than 20 ℃ to 24 ℃.

However, when the heat storage material having the phase transition temperature is applied to the above temperature range, there is a problem of rapid decay when the indoor temperature is adjusted to be close to the comfort region to some extent. Therefore, a temperature regulation device including a heat storage material in which the phase transition temperature of the heat storage material for cooling is about 26 ℃ or higher and the phase transition temperature of the heat storage material for heating is about 18 ℃ or lower is proposed, and the temperature is controlled by applying the above heat storage material according to seasons (for example, refer to patent document 1).

Detailed Description

Hereinafter, the present invention will be described with reference to preferred embodiments. The present invention is not limited to the embodiments described below, and may be appropriately modified within a scope not departing from the spirit of the present invention. In the embodiments described below, there may be a portion in which a part of the configuration is not shown and description thereof will be omitted, but with respect to the details of the omitted technique, it goes without saying that a well-known technique or a well-known technique is appropriately applied within a range not causing inconsistency with the following.

Fig. 1A and 1B are structural diagrams of a latent heat storage construction element according to a first embodiment of the present invention, in which fig. 1A is an overall structural diagram and fig. 1B is a partial structural diagram. The latent heat storage window that can be used as a window (regardless of the open/close state of the window) is described below as an example of the latent heat storage building element, and the latent heat storage building element is not limited to the above-described example applied to the latent heat storage window, and may be an exterior wall material having no window function. The latent heat storage building elements may be used in ceilings and under floors.

The latent heat storage window 1 of the example shown in fig. 1A includes substantially two sheets of plates 10 — a first plate 10a and a second plate 10b, a port seal 20, a cell array plate 30, an operating mechanism/unit 40, and a magnetic cylinder 50.

The two sheets 10 are transparent sheets arranged substantially parallel to each other. These plates 10 are made of a glass material, for example. The port seal 20 is inserted between the two sheets 10 at outer distal ends of the two sheets 10. The port seals 20 are provided at the outer end portions of the two sheet materials 10, so that an inner space is formed between the two sheet materials 10 and the port seals 20.

The cell array sheet 30 is located in an inner space formed by two sheets of the sheet 10 and the port seal 20. The cell array sheet 30 is a sheet in which a plurality of void portions as a plurality of cells S are arrayed in the vertical direction. A transparent latent heat storage material PCM is encapsulated in each unit cell S.

The latent heat storage material PCM has two or more components, e.g. the latent heat storage material PCM consists of Na₂SO₄10H₂O and a freezing point depressant. In the present embodiment, the freezing point depressant is ｃA component having magnetism and dispersed, and includes, for example, water-soluble magnetic ionic liquid 1-butyl-3-methylimidazolium tetrachlorodisulfonic acid (1-butyl-3-methylimidazolium tetrachlorodisphosate) having tetrachlorodisulfonic acid as an anion, which is described in JP-A-2007-131608. Although such a water-soluble ionic liquid is dispersed as an ionized ion in water, an anion (DyCl) is known₄ ^-) And cation (BMIM)⁺) DyCl close to each other and magnetic for convenience₄ ^-As will be explained below.

In the present embodiment, the cell array sheet 30 is a trapezoidal cross-section material, and the cells S are arranged in a linear form in a vertical direction therein, but is not limited thereto, and may also be a honeycomb cross-section material, in which the cell gaps are arranged vertically and horizontally in a honeycomb shape. That is, the cell array plate 30 is not limited to the above materials as long as the latent heat storage material can be retained.

The operating mechanism 40 operates the magnetic cylinder 50, as shown in fig. 1A and 1B, and includes an upper pulley 41, a lower pulley 42, a ladder (rope element) 43, an inner magnet 44, and an outer magnet 45. The upper sheave 41 and the lower sheave 42 are sheaves that are respectively located on the upper side and the lower side of the latent heat storage window 1. The ladder cord 43 is a loop wire material wound around the upper pulley 41 and the lower pulley 42. The ladder cord 43 is attached to opposite sides (both sides of the first plate material 10a and the second plate material 10 b) of the magnetic cylinder 50 in a state of not being directly connected to a magnet M to be described later.

The inner magnet 44 is a magnet located in the inner space formed by the two sheets of the plate material 10 and the port seal 20, and is connected to the ladder rope 43. The outer magnets 45 attract the inner magnets 44 through a sheet material 10a (only a portion of the sheet material 10 is shown in fig. 1B). For example, the inner magnet 44 and the outer magnet 45 are composed of a strong magnet such as neodymium magnet.

The magnetic cylinder 50 is a cylinder in which the magnet M is attached to the inner wall. As shown in fig. 1A, a magnetic cylinder 50 is disposed at the upper end of the unit cell S. The upper part of the unit cell S is a gas phase. Therefore, when the latent heat storage material PCM is in a liquid state, the lower half of the magnetic cylinder 50 is immersed in the latent heat storage material PCM, and the upper half thereof is not immersed in the latent heat storage material PCM.

In the above-described latent heat storage window 1, when the user moves the outer magnet 45 upward, the inner magnet 44 attracted by the outer magnet 45 also moves upward. Since the inner magnet 44 is connected to the ladder rope 43, the ladder rope 43 rotates with the upper and lower pulleys 41 and 42 and rotates the magnetic cylinder 50 through the horizontal hiding system. Therefore, the magnet M in the magnetic cylinder 50 can be immersed in (close to) the latent heat storage material PCM or can be prevented from being immersed in (separated from).

The function of the latent heat storage window 1 of the first embodiment will be described below. Fig. 2A and 2B are main part configuration diagrams illustrating the function of the latent heat storage window in the first embodiment, in which fig. 2A shows a state in which the magnet M is close to the latent heat storage material PCM, and fig. 2B shows a state in which the magnet M is far from the latent heat storage material PCM.

First, as shown in fig. 2A, assuming that the outer magnet 45 of the operating mechanism 40 (see fig. 1) is manipulated, the magnet M of the magnetic cylinder 50 is lower than the liquid surface LS of the latent heat storage material PCM. In this case, the magnet M is close to the latent heat storage material PCM, and its magnetic force acts on dysprosium tetrachloride ions (DyCl) having magnetism in the latent heat storage material PCM₄ ^-). Thus, dysprosium tetrachlorideIon (DyCl)₄ ^-) In a state of being unevenly distributed at the sides of the magnet M, and the concentration of the freezing point depressant is decreased in the latent heat storage material PCM except for the vicinity of the magnet M. Therefore, the melting point and the freezing point (phase transition temperature) of the latent heat storage material PCM can be raised to about 26 ℃, for example, so the latent heat storage window 1 can function in winter.

As shown in fig. 2B, assuming that the outer magnet 45 of the operating mechanism 40 (see fig. 1) is manipulated, the magnet M of the magnetic cylinder 50 is higher than the liquid level LS of the latent heat storage material PCM. In this case, the magnet M is separated from the latent heat storage material PCM, and the magnetic force thereof cannot act on dysprosium tetrachloride ions (DyCl)₄ ^-). Thus, dysprosium tetrachloride ion (DyCl)₄ ^-) In a dispersed state in the latent heat storage material PCM. Therefore, the freezing point depressant functions as usual, and the freezing point of the latent heat storage material PCM can be lowered to, for example, about 18 ℃, so the latent heat storage window 1 can function in summer.

As described above, according to the latent heat storage window 1 of the first embodiment, dysprosium tetrachloride ion (DyCl) of a specific composition is generated in response to a user operation₄ ^-) The uneven distribution, when performed, may not only reduce the ratio of the specific component in the other portion than the unevenly distributed portion, but may also change the melting point and the freezing point of the latent heat storage material.

A magnet M is provided, and the latent heat storage material PCM includes a component having magnetism and being dispersed, such as dysprosium tetrachloride, and is switchable between a state in which the magnet M is close to the latent heat storage material PCM and a state in which the magnet M is separated from the latent heat storage material PCM in response to a user operation. Therefore, in a state where the magnetic force is exerted while the magnet M is close to the magnet M, the magnetic component is attracted to the magnet M, and thus the component ratio of the latent heat storage material PCM in the region other than the close magnet M can be adjusted. Therefore, the melting point and the freezing point of the latent heat storage material PCM may be changed.

A ladder cord 43 that operates in response to a user operation is provided, and the magnet M is switched between a state close to and a state away from the latent heat storage material PCM in response to the operation of the ladder cord 43. Therefore, the melting point and the freezing point of the latent heat storage material PCM can be changed by the ladder cord 43 which can be rotated even in the slit.

In the first embodiment, the latent heat storage material PCM may not include a component having magnetism and dispersed as a freezing point depressant, which may be a component of the latent heat storage material. The latent heat storage material PCM is not limited to two components but may be composed of three or more components.

Next, a second embodiment of the present invention will be described. The latent heat storage window of the second embodiment has the following structure. Hereinafter, in describing the second embodiment, the same or similar elements as those of the first embodiment have the same reference numerals.

Fig. 3 is a structural view of the latent heat storage window 2 of the second embodiment. As shown in fig. 3, the latent heat storage window 2 of the second embodiment includes two sheets of plates 10, a port seal 20, and a cell array plate 30. As in the first embodiment.

In the second embodiment, the latent heat storage material PCM in the plurality of cells S may not include a component having magnetism and being dispersed.

Fig. 4 is a perspective view of latent heat storage window 2 and rotation mechanism of the second embodiment. In the following description, the structure of the latent heat storage window 2 (two sheets of the plate material 10, the port seal 20, and the cell array plate material 30) excluding the rotation mechanism (operation element) 60 is referred to as a laminated body L.

As shown in fig. 4, the outer side of the laminated body L of the latent heat storage window 2 includes a laminated body of transparent louvers TL1, which may also be called louvers. The latent heat storage window 2 includes an indoor louver TL2 inside the laminated body L. The latent heat storage window 2 of the second embodiment includes a rotation mechanism 60. The rotating mechanism 60 is capable of performing an operation (rotating operation) by a user, including the pivot 61, the window frame 62, and a locking unit, not shown, and the laminated body L is capable of half-rotating without contacting the blinds TL1 and TL 2.

More specifically, the pivot shaft 61 is a rotary lever located at one end LT2 of the upper or lower ends of the laminated body L. The pivot shafts 61 are provided on the left and right sides of the laminate L. The laminated body L is fitted into the window frame 62, and the laminated body L fitted into the window frame 62 is in a locked state in which the fitted state is maintained by a locking unit, not shown. The pivot shaft 61 is slidable with respect to the left and right members 62a of the window frame 62. The indoor louver TL2 can be opened and closed in an inward direction.

According to the above structure, the rotation operation can be performed as follows. First, assume that pivot 61 is located at the bottom end of sash 62. From this state, the indoor louver TL2 is opened. Then, the locking unit is released, and the portion LT1 on the side of the laminate L where the pivot is not provided is pushed out of the room. Next, the LT2 portion of the laminated body L on the side of the pivot shaft 61 is slid upward with respect to the window frame 62. Thereafter, when the end LT2 of the laminated body L reaches the upper end of the window frame 62, the laminated body L is embedded in the window frame 62 and locked by the locking unit. Finally, the indoor louver TL2 is closed.

Fig. 5A, 5B, 6A, and 6B are enlarged views of one of the plurality of cells S of the second embodiment, in which fig. 5A and 6A show a non-rotated state, and fig. 5B and 6B show a rotated state. As shown in fig. 5A, the latent heat storage window 2 of the second embodiment includes a membrane module (non-uniformly distributed cells) S1 in a unit cell S. The membrane module S1 is an ion exchange membrane (non-uniform distribution unit, membrane module) IEM1, causing the permeation rate of specific ions to be different from that of other ions. As shown in fig. 6A, the membrane module S1 may be composed of a semi-permeable membrane (non-uniform distribution unit, membrane module) SPM1, causing the permeation rate of ions to be different from that of water.

Here, the membrane module S1 is provided at the cell S at positions spaced apart in the height direction. More specifically, the membrane module S1 is disposed at a position near the upper surface US (or the lower surface BS) of the unit cell S, dividing the interior of the unit cell S into the small space SS and the main space MS. As shown in fig. 5B and 6B, although the stacked body L is semi-rotated in the vertical direction by the rotating mechanism 60, the membrane module S1 is located where the membrane module S1 is immersed when the latent heat storage material PCM is in a liquid state.

The function of the latent heat storage window 2 of the second embodiment will be described below with reference to fig. 5A and 5B. In the examples of FIGS. 5A and 5B, the latent heat storage material PCM has Na₂SO₄NaCl and water, in particular to a eutectic-eutectic type heat storage material, wherein the NaCl is used as a freezing point inhibitor and added into Na₂SO₄·10H₂And (4) in O.

First, in winter, the unit cells S are oriented as shown in fig. 5A. I.e. the ion exchange membrane IEM1 is located on the lower side. Here, the ion exchange membrane IEM1 is, for example, a monovalent ion permselective anion exchange membrane. Therefore, the chloride ions and water can permeate the ion exchange membrane IEM1, and the chloride ions and water are located in the small space SS. Therefore, sodium sulfate (specific component) is unevenly distributed in the main space MS, and thus the concentration of the freezing point depressant becomes lower relative to the latent heat storage material PCM in the main space MS. Here, in the heat storage material called eutectic type heat storage material, the degree of freezing point depression is influenced by the concentration of the freezing point depressant (second component of eutectic type) relative to the heat storage material (first component of eutectic type). In view of this, the freezing point of the latent heat storage material PCM in the unit cells S can be raised to, for example, about 26 ℃, so that the latent heat storage window 2 can be made to provide a temperature control effect for heating the indoor in winter.

On the other hand, for example, in summer, the stacked body L is half-rotated while keeping the left-right position of the stacked body L unchanged in the vertical direction by the rotating mechanism 60 as shown in fig. 4. In this case, the results are shown in fig. 5B. That is, most of the small space SS becomes the gas phase GP. Most of the chloride ions and water present in the small space SS shown in fig. 5A are transferred into the main space MS. Therefore, the concentration of the freezing point depressant in the main space MS becomes high relative to the latent heat storage material PCM. Here, in the heat storage material called eutectic-eutectic type heat storage material, the degree of freezing point depression is affected by the concentration of the freezing point depression agent with respect to the heat storage material, and the freezing point of the latent heat storage material PCM in the cell S can be lowered to, for example, about 18 ℃, so that the latent heat storage window 2 can be made to provide a temperature control effect for indoor cooling in summer.

The function of the latent heat storage window 2 of the second embodiment will be described with reference to fig. 6A and 6B. In the examples of fig. 6A and 6B, the latent heat storage material PCM has Na₂SO₄·10H₂O and excess water, more specifically Na₂SO₄·10H₂An aqueous solution of O (dissolution-evolution type heat-accumulative material). In addition, NaCl may be added as a freezing point depressant.

First, in winter, the unit cells S are oriented as shown in fig. 6A. Namely, the semipermeable membrane SPM1 is located on the lower side. Here, since the ion permeation rate of the semi-permeable membrane SPM1 is extremely low and the water is located in the small space SS, the sodium sulfate is unevenly distributed in the main space MS, and thus the sodium sulfate concentration increases. Here, the freezing point of the dissolution-evolution type heat storage material increases as the water concentration increases, and the freezing point of the latent heat storage material PCM in the cell S can be increased to, for example, about 26 ℃, so that the latent heat storage window 2 can be made to provide a temperature control effect for heating the room in winter.

On the other hand, in summer, the stacked body L is half-rotated while keeping the left-right position of the stacked body L in the vertical direction by the rotating mechanism 60 as shown in fig. 4. In this case, the results are shown in fig. 6B. That is, most of the small space SS becomes the gas phase GP. Most of the water present in the small space SS shown in fig. 6A is transferred into the main space MS. Therefore, the water capacity in the main space MS increases, and the concentration of sodium sulfate becomes low. Here, the freezing point of the dissolution-evolution type heat storage material becomes low as the water concentration is lowered, so that the freezing point of the latent heat storage material PCM in the unit cell S can be lowered to, for example, about 18 ℃, and thus the latent heat storage window 2 can be made to provide a temperature control effect of cooling the interior in summer.

As described above, according to the latent heat storage window 2 of the second embodiment, in the manner of the first embodiment, the melting point and the freezing point of the latent heat storage material PCM can be changed.

When the melting point and the freezing point of the latent heat storage material PCM are changed, the rotation operation is performed, and even if the precipitation is generated due to the use of the latent heat storage material PCM for a long time and thus the heat storage capacity is deteriorated, the rotation operation may break the precipitation, so that the heat storage capacity may be restored.

The latent heat storage window 2 of the second embodiment includes a membrane module S1 that is offset in the height direction within the plurality of unit cells S and partitions the interior into the small space SS and the main space MS. Therefore, the freezing point and the concentration of the latent heat storage material PCM at the upper and lower sides of the membrane module S1 are changed by the vertical direction rotation, and thus the melting point and the freezing point of the latent heat storage material PCM may be changed.

A third embodiment of the present invention will be described below. The latent heat storage window of the third embodiment has the following structure. Hereinafter, in describing the third embodiment, the same or similar elements as those of the second embodiment have the same reference numerals.

Fig. 7A, 7B, 8A, and 8B are enlarged views of one of the plurality of cells S of the third embodiment, in which fig. 7A and 8A show a non-rotated state, and fig. 7B and 8B show a rotated state. As shown in fig. 7A, a second membrane module (non-uniformly distributed cells) S2 is located within the cell S. The second membrane module S2 is the same as the membrane module S1, and is an ion exchange membrane (non-uniform distribution unit, second membrane module) IEM2 in the example shown in fig. 7A and 7B, and is also a second semi-permeable membrane (non-uniform distribution unit, second membrane module) SPM2 in the example shown in fig. 8A and 8B.

The second membrane module S2 forms a second small space SS2 approximately symmetrical in the height direction to the small space SS composed of the membrane module S1. That is, when the small space SS is disposed at a position close to the bottom surface BS of the unit cell S, the second membrane module S2 is disposed at a position close to the top surface of the unit cell S, and the capacity of the small space SS is substantially the same as the capacity of the second small space SS 2. Therefore, in the same manner as the membrane module S1, when the latent heat storage material PCM is in a liquid state, the second membrane module S2 remains immersed even if the stacked body L is half-rotated in the vertical direction by the rotating mechanism 60.

The function of the latent heat storage window 2 of the third embodiment will be described below with reference to fig. 7A and 7B. In the examples of FIGS. 7A and 7B, the latent heat storage material PCM has Na₂SO₄NaCl and water, in particular to a eutectic-eutectic type heat storage material, wherein the NaCl is used as a freezing point inhibitor and added into Na₂SO₄·10H₂And (4) in O. In the example shown in fig. 7A and 7B, the membrane module S1 and the second membrane module S2 are ion exchange membranes IEM1 and IEM2 (monovalent ion permselective anion exchange membranes) that cause the permeation rates of a specific ion and another ion to be different.

First, as shown in fig. 7A, it is assumed that ion exchange membrane IEM1 is located below second ion exchange membrane IEM 2. In this case, chloride ions exist in the main space MS and the small space SS, and sulfate ions exist only in the main space MS. However, when sulfate ions are in the state shown in fig. 7A for a long time, the sulfate ions move to the small space SS through the ion exchange membrane IEM 1. Therefore, the main space MS and the small space SS have substantially the same composition.

Then, when the rotation mechanism 60 is manipulated to rotate semi-in the vertical direction, the result is as shown in fig. 7B. In this case, the chlorine ions and water move to the main space MS through the ion exchange membrane IEM 1. On the other hand, it is generally difficult for sulfate ions to permeate through the ion exchange membrane IEM1, but since the volume of the aqueous solution in the small space SS is greatly reduced, the concentration of sulfate ions in the small space SS unexpectedly rises and rises, and thus sulfate ions also flow into the main space MS at an appropriate rate.

Water and chloride ions flow from the main space MS to the second small space SS 2. As for the sulfate ions in the main space MS, since the concentration difference of the sulfate ions in the main space MS and the second small space SS2 is not significant, the sulfate ions hardly penetrate through the second ion exchange membrane IEM 2. Therefore, the sodium sulfate is in a state of being unevenly distributed in the main space MS, and thus the concentration of the freezing point depressant in the main space MS is high relative to the latent heat storage material PCM.

Here, in the heat storage material called eutectic-eutectic type heat storage material, the degree of freezing point depression is affected by the concentration of the freezing point depressant with respect to the heat storage material, and in the same manner as the state shown in fig. 5A, the state shown in fig. 7B can be used as the latent heat storage window 2 that provides the temperature control effect of heating the indoor space in winter.

Next, the function of the latent heat storage window 2 of the third embodiment will be described with reference to fig. 8A and 8B. In the example shown in fig. 8A and 8B, the latent heat storage material PCM has Na₂SO₄NaCl and water by adding a freezing point depressant NaCl to Na₂SO₄·10H₂O (dissolution-precipitation type heat-accumulative material).

First, as shown in FIG. 8A, it is assumed that a semi-permeable membrane SPM1 is positioned below a second permeable membrane SPM 2. In this case, water is present in the small space SS, and chloride ions and sulfate ions are present only in the main space MS. However, when the chloride and sulfate ions are in the state shown in fig. 8A for a long time, the chloride and sulfate ions also move to the small space SS through the semi-permeable membrane SPM 1. Therefore, the main space MS and the small space SS have substantially the same composition.

Then, when the rotation mechanism 60 is manipulated to rotate semi-in the vertical direction, the result is as shown in fig. 8B. In this case, the water moves to the main space MS through the semi-permeable membrane SPM 1. On the other hand, chloride ions and sulfate ions are hardly permeated through the semipermeable membrane SPM1 in general, but since the volume of the aqueous solution in the small space SS is greatly reduced, the concentration of chloride ions and sulfate ions in the small space SS is significantly increased, and thus chloride ions and sulfate ions flow into the main space MS at a suitable rate.

Water flows from the main space MS to the second small space SS 2. As for the chloride ions and the sulfate ions in the main space MS, since the concentration difference of the chloride ions and the concentration difference of the sulfate ions are not significant in the main space MS and the second small space SS2, the chloride ions and the sulfate ions hardly penetrate through the second semi-permeable membrane SPM 2. Thus, the sodium sulfate is unevenly distributed in the main space MS.

Here, the concentration of water increases and the freezing point of the dissolution-precipitation type heat storage material increases, and the state shown in fig. 8B can be used as the latent heat storage window 2 providing the temperature control effect of heating the indoor space in winter in the same manner as the state shown in fig. 6A.

As described above, according to the latent heat storage window 2 of the third embodiment, in the manner of the second embodiment, the melting point and the freezing point of the latent heat storage material PCM can be changed. The rotary operation can break the precipitate and the heat storage capacity can be recovered. The concentrations of the freezing point depressant and the latent heat storage material PCM at the upper and lower sides of the membrane module S1 are changed, and thus the melting point and the freezing point of the latent heat storage material PCM can be changed.

The latent heat storage window 2 of the third embodiment further includes a second membrane module S2 forming a second small space that is substantially symmetrical in the height direction with the small space SS, the second membrane module S2 being composed of the same material as the membrane module S1. Therefore, for example, even when the components crossing the membrane module S1 inside the unit cell S are the same after the unit cell S is left for a long time, the concentrations of the freezing point depressant and the latent heat storage material on both upper and lower sides of the second membrane module S2 are changed by the vertical rotation, and thus the melting point and the freezing point of the latent heat storage material can be changed.

The fourth embodiment of the present invention will be described below. The latent heat storage window of the fourth embodiment has the following structure. Hereinafter, in describing the fourth embodiment, the same or similar elements as those of the first embodiment have the same reference numerals.

Fig. 9A, 9B, 10A, and 10B are enlarged views of one of the plurality of cells S of the fourth embodiment, in which fig. 9A and 10A show a non-rotated state, and fig. 9B and 10B show a rotated state. As shown in fig. 9A, magnets (non-uniformly distributed cells and magnetic material) M are located in the unit cells S. The magnet M is enclosed in a magnetic cover MC. The magnetic shield MC is located at a position (upper surface US in fig. 9A and 9B) offset in the height direction within the unit cell S, and is located within the gas phase GP in the non-rotated state shown in fig. 9A. On the other hand, in the rotating state shown in fig. 9B, the magnetic shield MC (magnet M) is immersed in the liquid phase LP.

As shown in fig. 10A, the inside of the unit cell S may not have the gas phase GP. In this example, the magnet M is enclosed in a magnetic box MB. The space inside the magnetic cartridge MB may prevent the latent heat storage material PCM from entering the inside thereof. The magnetic cassette MB is attached to the bottom surface BS. The magnet M is located on the bottom surface BS side of the magnetic cassette MB in the non-rotated state shown in fig. 10A, and on the upper surface US side of the magnetic cassette MB in the rotated state shown in fig. 10B. The magnetic cartridge MB may be attached to the upper surface US.

In the fourth embodiment, the latent heat storage material PCM has a composition including magnetism and dispersed as a freezing point depressant. The above freezing point depressant is the same as described in the first embodiment. Hereinafter, DyCl having the same magnetic properties as the first embodiment will be described₄ ^-。

The function of the latent heat storage window 2 of the fourth embodiment will be described below with reference to fig. 9A and 9B. In the example of fig. 9A and 9B, it is assumed that the latent heat storage material PCM is a magnetic-type heat storage material, which is a solidification point inhibitor dysprosium tetrachloride ion (DyCl)₄ ^-) Adding to Na₂SO₄·10H₂And O is in the atmosphere.

First, in summer, the cells S are oriented as shown in fig. 9A. That is, the magnet M is in a state of being located in the gas phase GP. Here, the first and second liquid crystal display panels are,dysprosium tetrachloride ions (DyCl) due to the magnets M being located in the gas phase GP₄ ^-) In a state of being dispersed in the liquid phase LP. Thereby, the freezing point depressant properly acts, and thus the freezing point of the latent heat storage material PCM in the unit cells S can be lowered to, for example, about 18 ℃, so that the latent heat storage window 2 providing a temperature control effect of cooling the interior in summer can be obtained.

On the other hand, for example, in winter, the stacked body L is half-rotated while keeping the left-right position of the stacked body L unchanged in the vertical direction by the rotating mechanism 60 as shown in fig. 4. In this case, the results are shown in fig. 9B. That is, because the magnet M is located in the liquid phase LP, dysprosium tetrachloride ion (DyCl)₄ ^-) Is attracted to the magnet M and concentrated near the magnet M. Therefore, the concentration of the freezing point depressant is decreased in the portion other than the vicinity of the magnet M. Accordingly, the freezing point of the latent heat storage material PCM in the unit cells S can be raised to, for example, about 26 ℃, and thus the latent heat storage window 2 providing a temperature control effect of cooling the indoor in winter can be obtained.

The function of the latent heat storage window 2 of the fourth embodiment will be described with reference to fig. 10A and 10B. Even in the example shown in fig. 10A and 10B, it is assumed that the latent heat storage material PCM is a magnetic-type heat storage material that is a solidification point inhibitor dysprosium tetrachloride ion (DyCl)₄ ^-) Adding to Na₂SO₄·10H₂And (4) in O.

First, in summer, the cells S are oriented as shown in fig. 10A. That is, the magnetic cassette MB is located at the lower side of the unit cell S, and the magnet M is located at the lower side of the magnetic cassette MB. At this time, the magnet M and the latent heat storage material PCM are in a state of being separated by a certain distance by the space inside the magnetic cartridge MB, and the magnetic force of the magnet M hardly reaches the latent heat storage material PCM. Thus, dysprosium tetrachloride ion (DyCl)₄ ^-) Dispersed in the liquid phase LP. Therefore, the freezing point depressant functions properly, and thus the freezing point of the latent heat storage material PCM in the unit cells S can be lowered to, for example, about 18 ℃, so that the latent heat storage window 2 that provides a temperature control effect of cooling the interior in summer can be obtained.

On the other hand, in winter, the layered body L is vertically moved by the rotating mechanism 60 shown in fig. 4The stack L is rotated half while keeping the left-right position thereof upward. In this case, the results are shown in fig. 10B. That is, the magnetic cassette MB is located at an upper side within the unit cell S, and the magnet M is located at a lower side of the magnetic cassette MB. At this time, the distance between the magnet M and the latent heat storage material PCM is equal to the thickness of the magnetic case MB, and the magnetic force of the magnet M easily reaches the latent heat storage material PCM. Accordingly, dysprosium tetrachloride ion (DyCl)₄ ^-) Is attracted to the magnet M and concentrated near the magnet M. Therefore, the concentration of the freezing point depressant is lowered in portions other than the vicinity of the magnet M. Therefore, the freezing point of the latent heat storage material PCM in the unit cells S can be raised to, for example, about 26 ℃, so that the latent heat storage window 2 that provides a temperature control effect of heating the indoor in winter can be obtained.

As described above, according to the latent heat storage window 2 of the fourth embodiment, in the manner of the second embodiment, the melting point and the freezing point of the latent heat storage material PCM can be changed. The rotation operation breaks the deposit, so that the heat storage capacity can be recovered.

According to the fourth embodiment, since the magnet M and the latent heat storage material PCM include the dispersed component having magnetism, such as dysprosium tetrachloride, the dispersed component having magnetism can be concentrated at the magnet M, so that the melting point and the freezing point of the latent heat storage material PCM can be changed.

The fifth embodiment of the present invention will be described below. The latent heat storage window of the fifth embodiment has the following structure. Hereinafter, in describing the fifth embodiment, the same or similar elements as those of the first embodiment are denoted by the same reference numerals.

Fig. 11 is a sectional view of a latent heat storage window of the fifth embodiment. As shown in fig. 11, the latent heat storage window 3 of the fifth embodiment has a configuration in which the cell array sheet 30 and the port seal 20 described in the second embodiment are sandwiched between the first and second structures ST1 and ST 2.

The first and second structures ST1 and ST2 generally include two sheets of sheet material 10, a vacuum port seal 70, an inclined portion 80, and a hydraulic fluid (liquid) HF, respectively.

The two sheets 10 are transparent sheets arranged substantially parallel to each other. These plates 10 can be made of, for example, a glass material that blocks water vapor. The vacuum port seal 70 is interposed between the two sheets of the sheet material 10 and is located at the outer ends of the two sheets of the sheet material 10. The inner space formed by the two sheets of sheet material 10 and the vacuum port seal 70 is in a vacuum state from the viewpoint of insulation. The inner space is not limited to a vacuum state but can be filled with a preset gas.

The inclined portion 80 is a transparent member inserted between the two sheet materials 10, and is folded twice to form a bent body having an approximately N-shaped cross section in the sectional view shown in fig. 10. In the inclined portion 80, one end portion 80a (to be described later, see fig. 12) is in contact with an inner wall of the first plate material (one plate material) 10a, and the other end portion 80b (to be described later, see fig. 12) is in contact with an inner wall of the second plate material (the other plate material) 10 b. The first plate material 10a at one end portion and the inclined portion 80 constitute a storage portion Res capable of storing the hydraulic fluid HF together.

Fig. 12 is a perspective view showing a detail of the inclined portion 80 in fig. 11. As shown in fig. 12, the inclined portion 80 includes a bottom plate 81, a top plate 82 disposed in parallel with the bottom plate 81, and a connecting plate 83 connecting the bottom plate 81 and the top plate 82.

The base plate 81 has the tip portion 80a, and comb teeth 81a protruding in a comb tooth shape are formed on the opposite side of the tip portion 80 a. Each end face EF of the comb-teeth 81a is a portion in contact with the inner wall of the second plate 10 b. The top plate 82 and the bottom plate 81 are point-symmetrical structures, and a connecting plate 83 is inserted in the middle. That is, the top plate 82 is formed with comb teeth 82a in a protruding comb tooth shape on the opposite side of the tip end portion 80b, and each end face EF of the comb teeth 82a is a portion that comes into contact with the inner wall of the first plate material 10 a. In this way, the opposite end portions (the distal end portion 80a and the end face EF) of the bottom surface 81 of the inclined portion 80 and the opposite end portions (the distal end portion 80b and the end face EF) of the top surface 82 thereof contact the two sheet materials 10, respectively. Accordingly, the inclined portion 80 provides support inside the two sheets of the plate material 10 in a vacuum state.

Please refer to fig. 11 again. In the present embodiment, the hydraulic fluid HF is a transparent liquid such as water or the like. The hydraulic fluid HF is not limited to water. The hydraulic fluid HF is stored in the storage part Res. The hydraulic fluid HF in the reservoir Res can be evaporated by the heat of the first plate material 10 a. The vaporized hydraulic fluid HF becomes vapor to reach the second plate 10 b. The hydraulic fluid HF changed into vapor is condensed and liquefied on the second plate material 10 b. The liquefied hydraulic fluid HF flows down along the inner wall of the second plate material 10b and accumulates on the ceiling 82 (see fig. 12) of the inclined portion 80. When the top plate 82 accumulates a certain amount or more of the hydraulic fluid HF, the hydraulic fluid HF flows into the reservoir Res from the gap between the comb-teeth portions 82a of the top plate 82. Here, the first plate material 10a functions as an evaporator by evaporating the hydraulic fluid HF, and the second plate material 10b functions as a condenser by condensing the hydraulic fluid HF. Accordingly, the first plate material 10a side is cooled by the loss of the evaporation heat, and the condensation heat of the second plate material 10b side is released.

In the above-described latent heat storage window 3, water (hydraulic fluid HF) is evaporated on the first sheet material 10a of the second structure ST2 at, for example, 21 ℃ or higher. When the evaporated water (steam) contacts the second plate material 10b, the evaporated water is cooled and liquefied, and returns to the storage part Res through the top plate 82 of the inclined part 80. In this process, the first sheet material 10a side is cooled by losing the heat of vaporization, and the heat of condensation on the second sheet material 10b side is released. The condensation heat released from the second plate material 10b side is stored in the latent heat storage material PCM.

When the temperature of the second plate material 10b side of the first structure ST1 is lower than 21 c, the heat of condensation is released from the second plate material 10b side by the evaporation of the hydraulic fluid HF in the storage part Res first structure ST1 side by the heat stored in the latent heat storage material PCM.

Therefore, the heat of the second structure ST2 side passes through the first structure ST1 side with the latent heat storage material PCM as a buffer. Accordingly, for example, in summer, the second structure ST2 becomes the inner side, so that the temperature control effect in the cooling chamber can be obtained without bringing in moisture.

In particular, the latent heat storage window 3 of the fifth embodiment can obtain a cooling effect by using the latent heat storage material PCM when the room temperature is, for example, 21 ℃ or higher even if the outside temperature is high. That is, since the latent heat storage material PCM is fixed at 21 ℃, when the room temperature is equal to or higher than 21 ℃, the heat in the room may be transferred to the latent heat storage material PCM, so that the cooling effect may be obtained in the room. For example, when the outside temperature is equal to or lower than 21 ℃ at night, the heat stored in the latent heat storage material PCM is released. Accordingly, the latent heat storage window 3 is buffered by the latent heat storage material PCM, so that the frequency of adjusting the indoor comfort can be increased.

In the latent heat storage window 3, the inclined portion 80 forms the storage portion Res together with the first plate material 10a, but the heat conductive portion may be attached to the inner surface of the first plate material 10a to form the storage portion Res together with the heat conductive portion. That is, the inclined portion 80 may form a storage portion Res together with other components on the first plate material 10a side. In the present embodiment, the hydraulic fluid HF reaches the second plate material 10b and is condensed and liquefied, but the present invention is not limited thereto, and a heat transfer part may be attached to an inner surface of the second plate material 10b, so that the hydraulic fluid HF may reach the heat transfer part and be condensed and liquefied.

When the inclined portion 80 has a liquid circulation structure that circulates the hydraulic fluid HF, the structure is not limited to that shown in fig. 11 and 12, and for example, may be a basic inclined structure (an inclined structure in which the distal end portion 80a is inclined toward the distal end portion 80 b).

To enhance evaporation, the first sheet material 10a may be heat absorbing glass (glass composition including metal such as glass including iron). At least one inner surface of the two sheets 10 is treated by infrared reflection to enhance the heat insulation performance.

The latent heat storage window 3 of the fifth embodiment includes a rotation mechanism 60 as shown in fig. 13, and is rotatable in both the vertical direction and the horizontal direction orthogonal to the vertical direction.

Fig. 13 is a perspective view of the latent heat storage window 3 and the rotation mechanism 60 of the fifth embodiment. In the example shown in fig. 13, the structure of latent heat storage window 3 other than rotation mechanism 60 (first and second structures ST1 and ST2, port seal 20, and cell array plate 30) is referred to as a composite laminate (flat body) CL.

As shown in fig. 13, the latent heat storage window 3 of the fifth embodiment further includes an outer fixing glass FG. Therefore, the latent heat storage window 3 shown in fig. 13 can be rotated half in the vertical and horizontal directions without causing the composite laminate CL to contact the fixing glass FG.

In the example shown in fig. 13, the rotating mechanism 60 includes a first pivot 63a, a second pivot 63b, a first sash 64a, a second sash 64b, and first and second locking units, not shown.

The first window frame 64a is a rectangular frame fixed to one side of a building. The second sash 64b includes a first pivot 63a at either of the left and right end portions LW1, the first pivot 63a being slidable with respect to the upper and lower members 62b of the first sash 64 a. The second pivot 63b is attached to a middle portion of the composite laminate CL in the height direction, and is rotatable at the center of the left and right members 62a2 of the rectangular second sash 64 b.

Therefore, the rotation operation can be performed as follows. First, it is assumed that the end portion LW1 on the first pivot 63a side of the second sash 64b is located at one of the left and right members 62a1 of the first sash 64 a. In this state, the first locking unit is opened, and the end portion LW2 of the second sash 64b on the side where the first pivot shaft 63a is not provided is pushed to the indoor side. Next, the second locking unit is opened, and the composite laminate CL is half-rotated in the vertical direction about the second pivot shaft 63 b. Next, the composite laminated body CL is locked by the second locking unit. Then, the end portion LW1 of the second sash 64b on the side of the first pivot 63a is slid to the other side of the left and right members 62a1 of the first sash 64 a. Thereafter, the second sash 64b is fitted into the first sash 64a such that the end portions LW2 of the second sash 64b become the left and right members 62a1 sides and are locked by the first locking unit.

As described above, in the latent heat storage window 3 including the fixed glass FG on the outdoor side, the composite laminated body CL is rotatable in both the vertical and horizontal directions.

As shown in fig. 12, in the inclined portion 80, since the bottom plate 81 and the top plate 82 are in a point-symmetrical structure with the connecting plate 83 interposed therebetween, the inclined portion 80 forms a storage section Res even if the composite laminated body CL is half-rotated in the vertical direction. That is, when the composite laminated body CL is half-rotated in the vertical direction, the reservoir Res is formed by the top plate 82 and the second plate material 10 b.

The function of the latent heat storage window 3 of the fifth embodiment will be described below. First, as shown in fig. 11, the first plate material 10a of the second configuration ST2 is set as the indoor side, and the second plate material 10b of the first configuration ST1 is set as the outdoor side.

In this state, for example, when the room temperature is equal to or higher than 21 ℃, the hydraulic fluid HF in the reservoir Res may be evaporated. The evaporated hydraulic fluid HF reaches the second plate material 10b outside the chamber and liquefies, flowing down along the inner surface of the second plate material 10 b. The hydraulic fluid HF flowing down passes through the top plate 82 of the inclined portion 80 and returns to the reservoir portion Res again. In this process, the first plate material 10a is cooled by the vaporization heat generated by vaporizing the hydraulic fluid HF, and the condensation heat of the hydraulic fluid HF is released through the second plate material 10 b. The released heat is stored by the latent heat storage material PCM. Accordingly, indoor heat may be transferred to the latent heat storage material PCM, so that an air conditioning effect of cooling the indoor may be provided.

With the first structure ST1, when the outside temperature is equal to or lower than 21 ℃, the hydraulic fluid HF repeats evaporation and condensation in the same manner as described above, thereby releasing the heat stored in the latent heat storage material PCM to the outside.

When the composite laminated body CL is rotated in the horizontal direction while maintaining the vertical position of the composite laminated body CL by the rotating mechanism 60 as shown in fig. 13, the operation is opposite to the above, and an air conditioning effect for heating the indoor can be obtained in winter. When the composite laminated body CL is rotated in the vertical and horizontal directions by the rotation mechanism 60, an effect of breaking the precipitates PR of the latent heat storage material PCM is obtained, thereby recovering the amount of stored heat.

As described above, according to the latent heat storage window 3 of the fifth embodiment, the melting point and the freezing point of the latent heat storage material PCM can be changed in the manner of the second embodiment. The rotation operation can break the precipitate, so that the heat storage capacity can be recovered. The concentrations of the freezing point depressant and the latent heat storage material PCM at the upper and lower sides of the membrane module S1 are changed, so that the melting point and the freezing point of the latent heat storage material PCM can be changed.

The latent heat storage window 3 of the fifth embodiment includes first and second structures ST1 and ST2 having two sheets of plate materials 10, a storage part Res of hydraulic fluid HF, and an inclined part 80 with a cell array plate 30 interposed therebetween. Therefore, first, when the hydraulic fluid HF is evaporated by the heat of the first plate material 10a side of the second structure ST2, the first plate material 10a side is cooled by providing the heat of evaporation. On the other hand, when the evaporated hydraulic fluid HF reaches the second plate material 10b side, the evaporated hydraulic fluid HF is cooled to be condensed and liquefied, and the condensation heat is released from the second plate material 10b side. The first structure ST1 is the same as above. Thus, a cooling effect can be obtained indoors.

Here, when a structure is used as a building element, heat does not flow from the sheet material 10a side to the sheet material 10b side as long as the temperature of both sides of the sheet material 10a side and the other sheet material 10b side of the structure is not adjusted. However, since the latent heat storage window 3 of the fifth embodiment includes the cell array plates 30 between the first and second structures ST1 and ST2, it is considered that the latent heat storage material PCM serves as a buffer and the temperature of the latent heat storage material PCM is maintained constant. Therefore, for example, although the outdoor temperature is higher than the room temperature, when the room temperature is equal to or higher than a certain temperature range, indoor heat may be transferred into the latent heat storage material PCM, and when the outside is lower than the certain temperature range, for example, at night, heat of the latent heat storage material PCM can be released to the outside. As described above, the latent heat storage material PCM serves as a buffer, so that the indoor comfort can be quickly adjusted.

Since the rotating mechanism 60 can be half-rotated in the horizontal direction, the rotating mechanism is rotated when it is necessary to change the direction of heat flow such as summer and winter and day and night, so that the room can be selectively cooled or heated.

The sixth embodiment of the present invention will be described below. The latent heat storage window of the sixth embodiment has the following structure. Hereinafter, in describing the sixth embodiment, the same or similar elements as those of the first embodiment are denoted by the same reference numerals.

Fig. 14 is a structural view of the latent heat storage window 4 of the sixth embodiment. As shown in fig. 14, the latent heat storage window 4 of the sixth embodiment includes two sheets of the plate material 10, the port seal 20, and the cell array plate material 30 as described in the first embodiment, and the magnetic pillars 50 located above the interiors of the cells S in the first embodiment. The electromagnet EM is located on the lower side of the magnetic cylinder 50 and becomes the latent heat storage material PCM side.

The latent heat storage material PCM of the sixth embodiment includes an energization portion (operation unit) 90 for switching an energization state and a deenergized state of the electromagnet EM. The user can switch between the energized state of the electromagnet EM and the deenergized state of the electromagnet EM by turning ON (ON) and OFF (OFF) of the energizing portion 90. When the current is applied through the current applying portion 90, the magnetic force of the electromagnet EM acts on the latent heat storage material PCM, and when the current is not applied (power is off), no magnetic force acts.

In the latent heat storage window 4, when electricity is supplied through the electricity supply portion 90, dysprosium tetrachloride ion (DyCl), which is a magnetic component, is present₄ ^-) Is unevenly distributed on the side of the electromagnet EM, thereby lowering the concentration of the freezing point depressant in portions other than the vicinity of the electromagnet EM. Therefore, the melting point and the freezing point (phase transition temperature) of the latent heat storage material PCM can be raised to about 26 ℃, for example, so that the latent heat storage window 4 can function in winter.

On the other hand, when the energization part 90 is turned off, dysprosium tetrachloride ion (DyCl) is generated₄ ^-) Dispersed in the latent heat storage material PCM. Accordingly, the freezing point depressant functions as usual, and the freezing point of the latent heat storage material PCM can be lowered to about 18 ℃, for example, so that the latent heat storage window 4 can function in summer.

In this way, according to the latent heat storage window 4 of the sixth embodiment, dysprosium tetrachloride ion (DyCl) as a specific component is present in response to a user operation₄ ^-) Uneven distribution, and therefore when uneven distribution is performed, it is possible not only to reduce the specific component ratio in the other regions except for the unevenly distributed region, but also to change the melting point and the freezing point of the latent heat storage material PCM.

According to the sixth embodiment, the energization portion 90 can switch the energization state of the electromagnet EM and the deenergized state of the electromagnet EM. Therefore, it is not necessary to install a complicated mechanism in the inner space between the two sheets of plates 10 and the port seal 20, and it is also not necessary to rotate a large part such as the two sheets of plates 10, so that the melting point and the freezing point of the latent heat storage material PCM can be easily changed.

As described above, although the present invention is described based on the embodiments, the present invention is not limited to the above-described embodiments, modifications may be added within a range not departing from the spirit of the present invention, and other techniques may be appropriately combined within a possible range. Further, well-known or well-known techniques may be combined to the extent possible.

For example, the rotating mechanism 60 shown in fig. 4 and 13 is described in the above embodiment, and the rotating mechanism 60 is not limited to the one shown in the drawings. The latent heat storage window 2 in the second to fourth embodiments can perform half rotation in the horizontal direction.

The latent heat storage window 2 of the fifth embodiment may be provided with a spray unit for spraying mist-like moisture. For example, when mist-like moisture is sprayed onto the second plate material 10b of the first structure ST1 shown in fig. 11, even if the outside air temperature is high, an effect of lowering the second plate material 10b to be close to the dew point can be obtained. A state similar to that when the outdoor air temperature is artificially lowered is thus generated, so that the heat on the latent heat storage material PCM side can be made to flow out of the room. The spraying may be performed when the first structure ST1 is located at the indoor side by the horizontal rotation of the rotation mechanism 60.

In the latent heat storage window 3 of the fifth embodiment, although the structure ST1 and ST2 are described as being located at opposite sides of the cell array plate 30, the present invention is not limited thereto, and the structure ST1 or ST2 may be provided only at one side.

In the above description, the composition (magnetic composition) of the latent heat storage material PCM may be not only a composition generating latent heat and a melting point and freezing point modifier, but also a dispersant and a nucleating agent.

In the above-described embodiment, the phase change temperature of the latent heat storage material PCM is changed in response to a user operation, but the present invention is not limited thereto, and for example, the phase change temperature of the latent heat storage material PCM may be automatically changed.

Fig. 15 is a structural diagram of a latent heat storage window of a modification. The latent heat storage window 5 of the modification is substantially the same as the latent heat storage window 4 of the sixth embodiment, but includes a controller 100, and the controller 100 automatically controls the energization unit 90. The control section 100 may be constituted by a CPU.

In the modification, the control unit 100 includes, for example, calendar information and can grasp the current month and date. Therefore, the control portion 100 may determine the season based on the current month and date, and when it is determined that the phase change temperature of the latent heat storage material PCM should be increased, the control portion 100 sets the energization portion 90 to the energized state. Accordingly, the magnetic force of the electromagnet EM acts on the latent heat storage material PCM, and a component having magnetism as a freezing point depressant is attracted to the electromagnet EM, thereby increasing the phase transition temperature of the latent heat storage material PCM. On the other hand, when it is determined that the phase change temperature of the latent heat storage material PCM should be decreased, the control portion 100 sets the energization portion 90 to the power-off state. Therefore, the magnetic force of the electromagnet EM does not act on the latent heat storage material PCM, and a component having magnetism is dispersed in the latent heat storage material PCM, thereby reducing the phase change temperature of the latent heat storage material PCM. As described above, the phase change temperature of the latent heat storage material PCM can be optimized without a user operation.

In the modification, for example, the energization unit 90 is controlled based on the calendar information, but the control is not limited to this, and for example, the control unit 100 may be connected to a temperature control device so that the energization unit 90 is turned off during cooling. The latent heat storage window 5 may include an illuminance sensor, and the control part 100 may calculate the number of hours of sunshine based on a signal of the illuminance sensor to determine a season and may also control the energization part 90 based on the determined season. In the same manner, the control portion 100 may input season information (although prediction information is available), and may also control the energization portion 90 to determine whether to set the latent heat storage material PCM to a high temperature or a low temperature based on the input weather information.

The control unit 100 is not limited to the control of the energizing unit 90, and may control the operating mechanism 40. In this case, the control part 100 may control the movement of the outer magnet 45 of the operating mechanism 40, may control the rotation of the upper and lower pulleys 41 and 42 without including the outer magnet 45, or may directly control the rotation of the magnetic cylinder 50.

The present application is based on japanese patent application (application No. 2017-248820) filed on 26.12.2017, the entire contents of which are incorporated herein by reference.
