Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.

The invention provides an energy recovery device of a refrigerator, which comprises an energy storage box 11 and a heating box 12, wherein one side of the energy storage box 11 is attached to the refrigerator 2 to absorb heat emitted by the refrigerator 2 during operation, and the other side of the energy storage box 11 is attached to the heating box 12 to release energy absorbed by the energy storage box 11 into the heating box 12, as shown in figure 1.

In the present embodiment, the energy recovery apparatus includes a housing 1, a partition plate 13 is provided in the housing 1, the partition plate 13 partitions the interior of the housing 1 into an energy storage box 11 and a heat generation box 12, the partition plate 13 has good thermal conductivity so as to transfer the energy storage box 11 into the heat generation box 12; the separator 13 may be made of a metal material having good thermal conductivity, such as aluminum or an aluminum alloy.

It should be noted that the heating box 12 can be used as a drying device, and articles to be dried (such as wet cloth, handkerchiefs, masks, cups and other small articles) are put into the heating box 12 for drying.

Specifically, as shown in fig. 1 and 2, the heat dissipated during operation of the refrigerator 2 is mainly generated by the condenser 21 and the compressor 22, the condenser 21 of the refrigerator 2 includes a serpentine tube and a heat dissipating portion 211 disposed on a side wall of the refrigerator, and the heat of the refrigerant in the serpentine tube is dissipated to the external environment of the refrigerator through the heat dissipating portion 211; the compressor 22 is disposed at the bottom of the refrigerator 2, the compressor 22 is connected to a heat pipe 221, one end of the heat pipe 221 is connected to the compressor 22, and the other end is connected to the heat dissipating unit 211, so that heat dissipated by the compressor 22 is dissipated through the heat dissipating unit 211.

One side of the energy storage box 11 is attached to the outer side of the heat dissipation portion 211, the outer wall of the energy storage box 11 close to one side of the heat dissipation portion 211 has good heat conductivity so as to transfer heat to the energy storage box 11, and the energy storage box 11 is filled with a phase-change material, so that when the refrigerator works, the phase-change material absorbs heat generated by the compressor 22 and the condenser 21, and when the phase-change material absorbs heat and reaches the phase-change temperature, phase change occurs so as to store the heat in the phase-change material; when the temperature of the phase-change material after the phase change is higher than the heat dissipation temperature of the refrigerator on the side of the heat dissipation portion 211 or the refrigerator starts to be stopped for defrosting, the phase-change material starts to dissipate heat and changes phase again, the heat is transferred into the heating box 12 through the partition plate 13, and the temperature of the heating box 12 is increased so as to dry the articles in the heating box.

In the actual use process, the phase change temperature of the phase change material needs to be higher than the lowest temperature of the heat dissipation portion 211, so that in the actual use process, the phase change material with the appropriate phase change temperature needs to be selected according to the parameters of the refrigerator, such as: when the refrigerator is a frequency conversion refrigerator, the rotating speed of the compressor is adjusted back and forth, so that the fluctuation range of the heat dissipation interval of the compressor is larger, namely the fluctuation range of the temperature interval of the heat dissipation part 211 is larger, therefore, a phase change material with the phase change temperature within the temperature interval can be selected according to the interval, and the phase change material can store heat and release the heat to the heating box 12; and a suitable phase change material can be selected according to the heat dissipation condition of the refrigerator, and the principle is the same as the above.

As shown in fig. 3, in order to facilitate the replacement of the phase change material, the energy storage tank 11 of the present embodiment is provided with a phase change material inlet 111 at an upper portion thereof, and a phase change material outlet 112 at a lower portion thereof, so that the replacement of the phase change material is facilitated, the energy recovery apparatus can be installed in different refrigerators, and different phase change materials can be filled in different refrigerators.

Preferably, in other embodiments, a phase-change material added with a photosensitive material may also be selected, and the phase-change temperature and the release rhythm of the phase-change material may be adjusted according to light; a novel mixed material is generated by combining fatty acid and a photosensitive organic compound, the photosensitive material can change the thermal property of the fatty acid, the mixed material can be naturally melted when reaching a melting point at a high temperature, and can still keep a melting state even if being cooled down when being exposed to ultraviolet rays, and the material can be immediately solidified and begins to release heat outwards when being placed under a common blue light LED; therefore, a light emitting system can be configured to realize heat release of the phase change material, and absorb heat when no light is emitted, and the phase change temperature of the phase change material can be lower than the lowest temperature of the heat dissipation portion 211.

Further, the heating box 12 comprises a switch door 122, one side of the switch door 122 is connected with the heating box 12 through a hinge, a handle 126 is arranged on the other side of the switch door 122, and the switch door 122 is opened through the handle so as to place the articles to be dried into the heating box 12 for drying; a plurality of exhaust holes 121 are arranged at the top of the heating box 12, and the water vapor with the drying articles is exhausted through the exhaust holes 121; a plurality of water discharge holes 123 are further formed at the bottom of the heat generating box 12, and the water discharge holes 123 are communicated with the water tank, so that water in the heat generating box 12 flows out through the water discharge holes 123.

Because the temperature in the heating box 12 is not controllable, in this embodiment, a temperature sensor 124 and a light emitting diode 125 connected with the temperature sensor 124 are further disposed in the heating box 12, the light emitting diode 125 is exposed outside, the temperature sensor 124 detects the temperature in the box in real time, when the detected temperature does not cause damage to a human body, the light emitting diode 125 emits green light to the outside, and when the detected temperature causes damage to the human body, the light emitting diode 125 emits red light to the outside; the prompting is made by the color of the light to ensure the safety of the user.

The invention also provides a refrigerator which comprises the energy recovery device.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
