Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings referred to below, the same reference numerals are given to members common to each other, and redundant description thereof will be omitted.

(embodiment 1)

Fig. 1 is a front view showing an air blower 1 for air-conditioning clothes according to embodiment 1 of the present invention. The blower 1 for air-conditioning clothes is used by being attached to the air-conditioning clothes 100. The blower 1 for air-conditioning clothes is inserted into a mounting hole formed in the air-conditioning clothes 100 and is mounted on the air-conditioning clothes 100. The blower 1 for air-conditioning clothes includes an axial flow blower and a centrifugal blower. The air-conditioning clothes blower 1 includes an air blowing unit 2 and a power supply unit 3, the air blowing unit 2 has a fan driven by a motor, and the power supply unit 3 supplies electric power to the air blowing unit 2.

The air blowing unit 2 includes: a fan, a motor for driving the fan, and a first housing 6 for housing the fan and the motor. The first casing 6 is formed in a circular shape in a front view of resin, and houses the motor and the fan. The first housing 6 includes a first contact portion 14 through which power supplied from the power supply unit 3 can be conducted. And a fan coupled to the rotary shaft 42.

The first contact portion 14 is formed of a metal plate that can be energized. The first contact portion 14 may be disposed at a desired position of the first housing 6, and is preferably disposed at a position close to the second housing 8 of the power supply unit 3. The first contact portion 14 may be formed integrally with the first housing 6 or may be separable.

The power supply unit 3 includes a second housing 8 capable of accommodating a battery. The second housing 8 is formed in a substantially rectangular shape in front view. The second housing 8 has a through hole penetrating from the front side to the back side. The through hole is formed in a shape through which the first housing 6 is inserted, and preferably, the first housing 6 is inserted through the through hole and engaged therewith.

The second housing 8 includes a plurality of holding portions 12 for accommodating the batteries 10. The battery 10 is constituted by a storage battery, for example. The second housing 8 includes a second contact portion 16 for supplying electric power from the battery 10 to the motor housed in the first housing 6. The second contact portion 16 is formed of a metal plate or the like that can be energized. The second contact portion 16 is disposed at a position corresponding to the first contact portion 14. The second contact portion 16 is in contact with the first contact portion 14 when the first housing 6 and the second housing 8 are engaged with each other. In the illustrated example, the second contact portion 16 is disposed at a position corresponding to the first contact portion 14 formed at the periphery of the through hole of the second housing 8. The second contact portion 16 may be formed integrally with the second housing 8 or may be separable.

Fig. 2 is a side view of the blower 1 for air-conditioning clothes according to embodiment 1. The blower unit 2 is detachably engaged with the power supply unit 3. The blower unit 2 is engaged with the power supply unit 3 by inserting the first housing 6 into a through hole formed in the second housing 8 of the power supply unit 3.

The first housing 6 includes a flange 20. The flange 20 is formed on the rear side of the first enclosure 6 as viewed from the airflow direction F1 when the fan is rotated. The flange 20 is formed to extend outward from the outer edge of the rear side of the first housing 6.

When the first enclosure 6 is inserted through the through-hole formed in the second enclosure 8 from the airflow direction F1, the flange 20 comes into contact with the periphery of the through-hole of the second enclosure 8. That is, the flange 20 abuts against the periphery of the through hole of the second housing 8, whereby the first housing 6 and the second housing 8 are engaged with each other.

When the first housing 6 and the second housing 8 are engaged with each other, the second housing 8 is disposed outside the outer diameter of the fan of the first housing 6 about the rotation shaft 42. When the fan is rotated about the rotation axis 42, air flows in the air flow direction F1. The second housing 8 is disposed outside the outer diameter of the fan, thereby preventing the second housing 8 from obstructing the air flow.

When the first housing 6 and the second housing 8 are engaged with each other, the first contact portion 14 and the second contact portion 16 are in contact with each other. Thereby, electric power is supplied from the power supply unit 3 to the blower unit 2, and the motor of the blower unit 2 is driven. The first contact portion 14 is urged in a direction of coming into contact with the second contact portion 16 by a spring or the like, although not shown. Alternatively, the second contact portion 16 may be urged in a direction of coming into contact with the first contact portion 14 by a spring or the like. Thereby, the first contact portion 14 and the second contact portion 16 are more reliably brought into contact with each other, and good current can be conducted.

When the fan is rotated by driving the motor, air is sucked from the outside of the air-conditioning clothes 100 and discharged in the air-conditioning clothes 100 in the air flow direction F1. The air discharged into the air-conditioning garment 100 is discharged from the openings of the sleeve or neck to the outside. That is, the air in the air-conditioning garment 100 does not stagnate and flows, and thus draws heat from the skin surface of the wearer. Thus, abnormal rise of body temperature of the wearer is prevented, and heat stroke can be avoided.

Fig. 3 is a perspective view showing an example of the power supply unit 3 according to embodiment 1. The second housing 8 has a through hole penetrating in the thickness direction. And a through hole formed in substantially the same shape as the cross section of the first housing 6 in a front view, and through which the first housing 6 can be inserted.

The second housing 8 includes a housing 32 that can house medicines. The housing portion 32 is provided at the periphery of the through hole and is separated from the through hole by a wall surface. The housing section 32 includes a ventilation section 30 on a wall surface on the through hole side. The ventilation portion 30 may be formed of a hole penetrating the wall surface, or may be formed of a fiber that can ventilate. In the example shown in fig. 3, the ventilation portion 30 is a notch formed in a wall surface that separates the housing portion 32 and the through hole.

The storage section 32 can store: a fabric such as a cloth or cotton flower impregnated with a chemical such as a deodorant or insect repellent. Air is introduced from the fan side through the ventilation portion 30, or air is discharged from the housing portion 32 to the fan side. The structure and function of the ventilation unit 30 will be described later.

Fig. 4 is a front view showing an example of the power supply unit 3 according to embodiment 1. As described above, the second housing 8 has the through hole in the thickness direction near the center. The second housing 8 includes a holding portion 12 for accommodating the battery 10 at the periphery of the through hole. The holding portion 12 is a frame formed in a shape corresponding to the shape of the battery 10, and is integrally formed with the second housing 8.

The holding parts 12 are disposed in a plurality of positions around the periphery of the through hole. The holding portion 12 is disposed so that the longitudinal direction thereof is close to the periphery of the through hole. The holding portion 12 is disposed offset to the periphery of the through hole. Accordingly, when the blower 1 for air-conditioning clothes is attached to the air-conditioning clothes 100, the blower 1 for air-conditioning clothes is stabilized in a state where the holding portion 12 is located on the lower side due to the weight of the battery 10 accommodated in the holding portion 12.

That is, the center of gravity of the air-conditioning-clothes blower 1 is located below the rotation axis of the fan by the weight of the batteries 10 accommodated in the plurality of holding portions 12. Therefore, the rotation of the air-conditioning clothes blower 1 itself with the rotation of the fan can be favorably suppressed.

In the example shown in fig. 3 and 4, the second housing 8 is provided with a plurality of holding portions 12, but unlike this, one holding portion 12 capable of storing a plurality of batteries 10 may be provided. This can reduce the number of steps for forming the second enclosure 8.

The second housing 8 includes a second contact portion 16 on the inner peripheral surface of the through hole. The second contact portion 16 is disposed at a position corresponding to the first contact portion 14 formed in the first housing 6. The second contact portion 16 may be urged in the through hole center axis direction by a spring or the like.

The second housing 8 has a housing portion 32 capable of housing a medicine at the periphery of the through hole. As described above, the receiving portion 32 is located at the periphery of the through hole. The housing 32 is disposed near the outer edge of the fan when the blower unit 2 is engaged with the power supply unit 3. The housing 32 includes a ventilation portion 30 on a wall surface separating the housing 32 and the through hole. The ventilation portion 30 may be a hole provided to penetrate through a wall surface separated from the through hole, or may be a notch.

Fig. 5 is an enlarged view of the periphery of the vent portion 30 of embodiment 1. In the example of fig. 5(a), the ventilation portion 30 is a notch formed in the upper side of the wall surface that separates the housing portion 32 and the through hole. When the air is pushed out in the airflow direction F1 (see fig. 2) by the rotation of the fan, the air pressure on the fan side is higher than the air pressure in the housing section 32.

Therefore, air flows from the fan side into the housing 32 through the ventilation portion 30. The housing portion 32 has a hole (not shown) in a wall surface facing the airflow direction F1 and located behind the housing portion and not facing the fan. When the air flowing in from the fan side flows out from the hole, the chemical disposed in the housing 32 is vaporized, and the generated particles are discharged together with the air.

The particles discharged together with the air are discharged to the outside of the air-conditioning garment 100 through grooves formed in the power supply unit 3 and the air blowing unit 2. For example, fibers soaked with the insect repellent are disposed in the storage section 32, and the insect repellent is vaporized when the fan is rotated, and the generated particles are discharged to the outside of the air-conditioning clothes 100. Thus, the particles float around the air-conditioning clothes 100, and the vermin can be kept away from the wearer.

The ventilation portion 30 is preferably inclined from the fan side toward the housing portion 32 side toward the forward side in the airflow direction F1. This is because the air pushed out in the airflow direction F1 more easily flows from the fan side into the ventilation portion 30.

In the example shown in fig. 5(b), the ventilation portion 30 is a hole formed through a wall surface separating the housing portion 32 and the through hole. In the illustrated example, the vent portion 30 is formed rearward in the airflow direction F1 (see fig. 2). By rotating the fan, the air on the fan side becomes higher in pressure than the air in the housing 32.

In this case, the air on the fan side having a high air pressure flows into the housing 32 through the ventilation portion 30. Accordingly, the air in the housing 32 having a low air pressure is pushed out to the fan side from the ventilation portion 30. Thereby, the chemical is vaporized in the housing 32, and the generated particles are discharged to the fan side through the ventilation portion 30. Then, these particles are diffused in the airflow direction F1 blown by the rotation of the fan.

For example, when fibers impregnated with a deodorant or the like are disposed in the housing 32, particles of the gasified deodorant or the like are discharged to the fan side through the ventilation portion 30, and are diffused into the air-conditioning clothing in the airflow direction F1.

In this case, the hole constituting the ventilation portion 30 preferably extends from the housing portion 32 toward the fan side and is inclined toward the front side with respect to the airflow direction F1. Thus, the air in the housing 32 with low air pressure is easily discharged to the fan side through the ventilation part 30, so that the particles of the chemical can be efficiently discharged to the fan side.

Fig. 6 is a side view showing an example of the blower unit 2 according to embodiment 1. The blower unit 2 includes a first housing 6 that houses a fan and a motor. The first housing 6 includes: a first contact portion 14 capable of conducting electric power supplied from the power supply unit 3, and a flange 20 (first flange) formed on the back surface side.

The first housing 6 accommodates: a fan, a motor housing 40 housing the motor, and a rotating shaft 42 standing from the motor housing 40 in the airflow direction F1. The motor may be an AC motor or a DC motor. The first enclosure 6 is formed in a dome shape in side view, and forms a pointed tower in an airflow direction F1 generated by rotating the fan.

The first contact portion 14 is formed to protrude from a side wall of the first housing 6. The first contact portion 14 is disposed at a position corresponding to the second contact portion 16 of the second housing 8. The first contact portion 14 may be urged outward by a spring or the like.

The flange 20 (first flange) extends continuously outward from the end of the first enclosure 6 on the rear side in the airflow direction F1. The flange 20 may be formed integrally with the first housing 6 or may be detachably joined to the first housing.

Fig. 7 is a side view showing an example of the structure of the air-conditioning clothes blower 1 according to embodiment 1. When the air blower 1 for air-conditioning clothes of the present embodiment is mounted on the air-conditioning clothes 100, the air blowing unit 2 is inserted into the mounting hole from the outer surface side of the air-conditioning clothes 100 toward the airflow direction F1. The flange 20 (first flange) is formed to have a size of a cloth abutting on the periphery of the mounting hole. The flange 20 (first flange) is brought into contact with the cloth around the mounting hole, thereby preventing the air blowing unit 2 from entering the air-conditioning garment 100.

In a state where the flange 20 (first flange) is in contact with the cloth at the periphery of the mounting hole, the air blowing unit 2 is inserted through the through hole of the power supply unit 3 from the inner surface side of the air-conditioning garment 100. The through hole of the second housing 8 has a shape corresponding to the cross-sectional shape of the first housing 6 perpendicular to the rotation shaft 42. Therefore, the blower unit 2 is favorably engaged with the through hole of the power supply unit 3 when inserted therethrough.

When the blower unit 2 is engaged with the power supply unit 3, the first contact portion 14 and the second contact portion 16 abut against each other. Thereby, electric power is supplied from the power supply unit 3 to the blower unit 2. Since the power is not supplied from the power supply unit 3 to the air blowing unit 2 through the electric wire, the power can be stably supplied without the risk of breakage of the electric wire regardless of the movement of the wearer of the air-conditioning garment 100. Further, the first contact portion 14 and the second contact portion 16 are pressed against each other, whereby the engagement between the blower unit 2 and the power supply unit 3 is further strengthened.

The second housing 8 includes a receiving portion 22 (first receiving portion). When the blower 1 for air-conditioning clothes is attached to the air-conditioning clothes 100, the receiving portion 22 (first receiving portion) sandwiches the cloth around the attachment hole with the flange 20 (first flange). Thus, the blower 1 for air-conditioning clothes is not detached from the air-conditioning clothes 100 and can be mounted well.

In the present embodiment, the blower unit 2 has an operation unit for controlling the ON/OFF of the motor disposed ON the rear side of the first housing 6 in the airflow direction F1. When the blower 1 for air-conditioning clothes is attached to the air-conditioning clothes 100, the operation portion is exposed to the outside. Therefore, the ON/OFF switching operation of the blower 1 for air-conditioning clothes can be easily performed.

(embodiment 2)

Fig. 8 is a side view showing a blower 1 for air-conditioning clothes according to embodiment 2 of the present invention. In embodiment 2, the air blowing unit 2 includes a first housing 6 that houses a fan. The first housing 6 includes a motor housing 50 in the vicinity of the dome-shaped tip tower. The first housing 6 is configured such that the motor housing 50 is connected to one end of the rotary shaft 42.

The first contact portion 14 is provided at the opposite end of the rotation shaft 42. In embodiment 2, the first contact portion 14 is a pin hole made of a metal having conductivity. The first contact portion 14 is formed on the rear side in the airflow direction F1. The first contact portion 14 is formed at: and a position corresponding to the second contact portion 16 formed in the second housing 8.

The power supply unit 3 includes a second housing 8. In embodiment 2, the second housing 8 includes a holding portion 12 for accommodating the battery 10 in the vicinity of the center portion on the front surface side, and a second contact portion 16. The second contact portion 16 is formed at a position corresponding to the first contact portion 14 in the vicinity of the front side center portion. The holding portion 12 is formed to protrude forward near the center of the front surface side.

In embodiment 2, the second enclosure 8 includes a flange 60 (second flange) extending from the center of the rear portion. The first housing 6 includes a receiving portion 62 (second receiving portion) that can be brought into contact with the flange 60.

A method of attaching the blower 1 for air-conditioning clothes of embodiment 2 to the air-conditioning clothes 100 will be described. The air blowing unit 2 is disposed on the inner surface side while sandwiching the mounting hole of the air-conditioning garment 100, and the power supply unit 3 is disposed on the outer surface side while sandwiching the mounting hole of the air-conditioning garment 100. The holding portion 12 and the second contact portion 16 formed near the center of the second enclosure 8 are inserted into the mounting hole, and the first contact portion 14 and the second contact portion 16 arranged on the inner surface side of the air-conditioning garment 100 are brought into contact with each other.

The back surface of the first housing 6 is formed in a shape engageable with the front surface of the second housing 8 including the holding portion 12. Therefore, the front surface of the second housing 8 is engaged with the back surface of the first housing 6, and the first contact portion 14 is brought into contact with the second contact portion 16. The first contact portion 14 and the second contact portion 16 are not electrically connected through wires, but are electrically connected by contact. Accordingly, since the power supply unit 3 can supply the electric power to the air blowing unit 2 without the need of the electric wire, the electric wire is not damaged regardless of the movement of the wearer of the air-conditioning garment 100, and the electric power can be stably supplied.

The flange 60 (second flange) has a size larger than the mounting hole. Therefore, the flange 60 (second flange) abuts on the cloth at the periphery of the mounting hole. The receiving portion 62 (second receiving portion) and the flange 60 (second flange) sandwich the cloth around the mounting hole. Therefore, by engaging the air blowing unit 2 with the power supply unit 3 with the mounting hole interposed therebetween, the air blower 1 for air-conditioning clothes can be easily mounted on the air-conditioning clothes 100, and the air blower can be prevented from falling off from the air-conditioning clothes 100.

Fig. 9 is a rear view of the power supply unit 3 according to embodiment 2. The second housing 8 includes a holding portion 12 near the center portion thereof and a plurality of spokes 70 radially extending from the center. The flange 60 (second flange) extends continuously outward from the outer end of the spoke 70.

Air gaps are formed between the spokes 70 to allow air to pass through the gaps in response to rotation of the fan, and the air is drawn toward the fan. The flange 60 (second flange) is formed to be able to abut against the receiving portion 62 (second receiving portion) and has a predetermined width. The diameter of the back surface of the second enclosure 8 of embodiment 2 is larger than the diameter of the mounting hole of the air-conditioning garment 100.

Therefore, the flange 60 (second flange) abuts against the cloth around the mounting hole when the air-conditioning garment 100 is mounted. Further, since the receiving portion 62 (second receiving portion) of the air blowing unit 2 is disposed at a position where it can be brought into contact with the flange 60 (second flange) from the inner surface side with the mounting hole interposed therebetween, the cloth at the periphery of the mounting hole is sandwiched between the flange 60 (second flange) and the receiving portion 62 (second receiving portion).

In embodiment 2, the second enclosure 8 may be provided with a light emitting section on the back side in the airflow direction F1. For example, the light emitting unit is an LED lamp disposed at a predetermined position on the back surface side of the second housing 8, and emits light by electric power supplied from the battery 10. Alternatively, the light emitting section may be coated with a fluorescent paint or a phosphorescent paint at a predetermined position on the back surface side of the second housing 8 to reflect or emit light.

(embodiment 3)

Fig. 9 is a side view of a blower 1 for air-conditioning clothes according to embodiment 3 of the present invention. The blower 1 for air-conditioning clothes of embodiment 3 includes: the air-conditioning garment 100 includes an air blowing unit 2, a power supply unit 3 for supplying power to the air blowing unit 2, and a fixing ring 74 for sandwiching cloth around a mounting hole of the air-conditioning garment 100 with a flange 20 (first flange).

The blower unit 2 includes a first housing 6 for housing a fan. The first housing 6 includes a first contact portion 14 at a predetermined position on a side surface. The first contact portion 14 of embodiment 3 is formed in a hook shape from a conductive metal.

The first housing 6 may be provided with a storage portion (not shown) formed of a fabric such as a cloth impregnated with a chemical such as a deodorant or insect repellent in the vicinity of the dome-shaped tip tower portion. The housing section is provided with a ventilation section on the outside. The housing portion is disposed on the front side of the fan in the air flow direction F1, and thereby particles of the medicine can be favorably diffused by the air flow generated by the rotation of the fan.

The power supply unit 3 includes a second housing 8 that houses a battery 10. The second housing 8 includes a second contact portion 16 engageable with the first contact portion 14 of the first housing 6. The second contact portion 16 protrudes outward from the second housing 8 in a hook-like shape, and engages with the first contact portion 14. The second housing 8 is engaged with the first housing 6 by engaging the second contact portion 16 with the first contact portion 14.

The fixing ring 74 is formed in a ring shape having a hole in the center. In a state where the first housing 6 and the second housing 8 are engaged with each other, the first housing 6 can be inserted into the hole of the fixed ring 74 from the front. The hole of the fixing ring 74 corresponds to the cross-sectional shape of the first housing 6 perpendicular to the rotation shaft 42.

When the first enclosure 6 is inserted into the fixing ring 74, the flange 20 (first flange) abuts against the fixing ring 74. In the case where the blower 1 for air-conditioning clothes according to embodiment 3 is attached to the air-conditioning clothes 100, the first casing 6 is inserted into the attachment hole from the outer surface side of the air-conditioning clothes 100. The flange 20 of the first housing 6 is formed to be larger than the diameter of the mounting hole, and thus contacts the cloth around the mounting hole.

The first enclosure 6 is inserted into the hole of the fixing ring 74 from the inner surface side of the air-conditioning garment 100, whereby the cloth around the mounting hole can be sandwiched by the fixing ring 74 and the flange 20 (first flange). Thereby, the blower 1 for air-conditioning clothes can be attached to the air-conditioning clothes 100, and the air-conditioning clothes 100 can be prevented from falling off.

(embodiment 4)

Fig. 11 is a diagram showing a structure of a blower 1 for air-conditioning clothes according to embodiment 4 of the present invention. In embodiment 4, the air blower 1 for air-conditioning clothes includes: the fan-driving electric vehicle includes a main body 90 for driving a fan and a battery 10 (power supply unit), and a rear shield 94 engageable with the main body 90.

The main body 90 includes: a motor housing part 40 housing a motor, a holding part 12 housing a battery 10, and a fan disposed around a rotating shaft 42. In the present embodiment, these are housed in one housing. The motor housing portion 40 and the holding portion 12 are disposed at positions that do not interfere with the rotation of the fan. The battery 10 and the motor are not connected to each other by a wire or the like in the housing. Thus, the electric power cannot be supplied to the motor only by the main body 90, and the motor is not driven.

The main body 90 includes: and a first locking portion 75 that engages with a second locking portion 76 formed on the rear surface shield 94. The first locking portion 75 is, for example, a screw groove formed in the inner surface of the housing. In contrast, the first locking portion 75 may be formed on the outer surface of the housing.

The rear shield 94 is engaged with the rear surface side of the main body 90 in the airflow direction F1, and blocks the rear surface side of the main body 90, thereby protecting components such as a motor disposed in the housing of the main body 90. The rear shield 94 includes a second locking portion 76 at a position corresponding to the first locking portion 75 of the main body 90. The second locking portion 76 is a screw groove formed in a shape corresponding to the first locking portion 75.

When the main body 90 and the rear shield 94 are engaged, the cloth formed around the periphery of the mounting hole of the air-conditioning garment 100 is sandwiched between the portions where the main body and the rear shield abut against each other. Thus, when the blower 1 for air-conditioning clothes of the present embodiment is attached to the air-conditioning clothes 100, the air-conditioning clothes 100 are prevented from falling off.

Unlike the above, the main body 90 and the rear surface shield 94 may have a shape that fits together. In this case, the main body 90 may not have the first locking portion 75, and the rear surface shield 94 may not have the second locking portion 76.

Fig. 12 is a front view of a main body 90 according to embodiment 4. The main body 90 includes the motor housing 40 and the holding portion 12 in the housing as described above. The main body 90 includes a first locking portion 75 on the inner periphery of the housing.

The main body 90 includes a third contact portion 78 connected to the holding portion 12 for storing the battery 10 by a wire. The third contact portion 78 is formed of an electrically conductive metal or the like, and is disposed at a predetermined position in the first locking portion 75.

The main body 90 includes a fourth contact portion 79 connected to the motor housed in the motor housing portion 40 by a wire. The fourth contact portion 79 is formed of a metal or the like that can be energized. The fourth contact portion 79 is disposed at a position not in contact with the third contact portion 78 in the first locking portion 75.

Fig. 13 is a perspective view of the rear surface shield 94 according to embodiment 4. The rear shield 94 engages with the main body 90 from the rear side. The rear shield 94 includes a second locking portion 76 formed of a screw groove, and the second locking portion 76 is engageable with the first locking portion 75.

The rear surface shield 94 includes a conductive portion 77 that is in contact with the third contact portion 78 and the fourth contact portion 79. The conductive portion 77 is disposed at a position corresponding to the third contact portion 78 and the fourth contact portion 79. The conductive portion 77 abuts against the third contact portion 78 and the fourth contact portion 79 when the main body portion 90 engages with the rear surface shield 94. The conductive portion 77 is formed of a conductive metal or the like.

The conductive portion 77 is disposed in the second locking portion 76. The conductive portion 77 is disposed at a position corresponding to the third contact portion 78 and the fourth contact portion 79 in the second locking portion 76. That is, when the first locking portion 75 and the second locking portion 76 are engaged, the conductive portion 77 abuts against the third contact portion 78 and the fourth contact portion 79.

When the conductive portion 77 is disposed in the second locking portion 76 and the third contact portion 78 and the fourth contact portion 79 are disposed in the first locking portion 75, the conductive portion 77 abuts against the third contact portion 78 and the fourth contact portion 79 when the first locking portion 75 and the second locking portion 76 are locked to each other. In this way, even if the conductive portion 77 is not positioned in contact with the third contact portion 78 and the fourth contact portion 79, it is sufficient to engage the first locking portion 75 with the second locking portion 76, and the efficiency of the operation is improved.

The conductive portion 77 relays electric power between the third contact portion 78 and the fourth contact portion 79 when they are in contact with each other. That is, power is transmitted from the battery 10 to the third contact portion 78, and the third contact portion 78 relays the conductive portion 77 to allow the power to reach the fourth contact portion 79. Then, electric power is supplied from the fourth contact portion 79 to the motor housed in the motor housing portion 40 via the electric wire.

The main body 90 is engaged with the rear shield 94, and thereby the motor can be driven by supplying electric power. When the blower 1 for air-conditioning clothes of the present embodiment is not used, the back shield 94 is separated from the main body 90, thereby suppressing power loss of the battery 10.

The back surface side of the main body 90 is open in a state where the main body 90 and the back shield 94 are not engaged with each other. Since no power is supplied to the motor in a state where the rear shield 94 is not engaged with the motor, even when a child inserts a finger into the motor through the opening of the main body 90, the finger is not damaged by the rotation of the fan, and the safety is high.

The third contact portion 78 and the fourth contact portion 79 may be disposed outside the first locking portion 75, and the conductive portion 77 may be disposed outside the second locking portion 76. The conductive portion 77 abuts against the third contact portion 78 and the fourth contact portion 79 when the main body portion 90 engages with the rear surface shield 94.

(for air-conditioning clothes 100)

Fig. 14 is a diagram showing an example of an air-conditioning garment 100 to which the blower 1 for air-conditioning garment is attached. Fig. 14(a) is a rear view of the air-conditioning garment 100 in a state where the blower 1 for air-conditioning garment is attached. The air-conditioning garment 100 includes a mounting hole in a lower portion of a back surface side. In the drawings, although the case where a plurality of mounting holes are provided is illustrated, one mounting hole may be provided.

When the air-conditioning clothes-taking blower 1 is driven, air is sucked from the outside of the air-conditioning clothes 100 and discharged to the inside of the air-conditioning clothes 100. This promotes the evaporation of sweat from the wearer wearing the air-conditioning garment 100, and suppresses the rise in body temperature of the wearer.

The air-conditioning garment 100 includes a constriction limiting section 104 (ventilation adjusting section) near the boundary between the shoulder and the sleeve. The constriction limiting portion 104 (ventilation adjusting portion) may be formed by sewing an elastic body such as a rubber band into the sleeve portion. Alternatively, the sleeve portion may be wound with an inner circumference width adjustment cord. The constriction part 104 (ventilation adjusting part) has a function of adjusting the amount of air flowing from the body part of the air-conditioning garment 100 to the sleeve part.

The inner peripheral width of the sleeve portion is narrowed by the constriction of the constriction portion 104 (ventilation adjustment portion), and the amount of air flowing from the body portion into the sleeve portion is reduced. When the air-conditioning clothes-use blower 1 is driven, air flows into the air-conditioning clothes 100 by the air-conditioning clothes-use blower 1, the volume of air inside the air-conditioning clothes 100 increases, and the air-conditioning clothes 100 expands. When the constriction portion 104 (ventilation adjustment portion) constricts, the inner peripheral width of the sleeve portion is narrowed, so that the inflow amount of air into the sleeve portion can be suppressed, and the expansion of the sleeve portion due to air can be suppressed. This prevents the movement of the arms of the wearer from being hindered by the inflated sleeves.

Fig. 14(b) is an enlarged view of the mounting portion of the blower 1 for air-conditioning clothes. In the illustrated example, the flange 20 (first flange) of the first enclosure 6 is exposed to the outside of the air-conditioning garment 100, and the second enclosure 8 is hidden inside the air-conditioning garment 100.

The cloth around the mounting hole is sandwiched by the flange 20 (first flange) and the receiving portion 22 (first receiving portion), and the blower 1 for air-conditioning clothes is mounted well. An operation unit for controlling the driving of the motor may be attached to the back surface side of the first housing 6. The operation portion is provided at a portion exposed from the air-conditioning garment 100, whereby the wearer can easily operate the operation portion.

(modification example)

While the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications can be applied.

For example, in the above embodiment, the case where the storage unit 32 capable of storing the cloth or the like soaked with the medicine is provided is described. However, the present invention is not limited to this, and the first housing 6 may be provided with a medicine arrangement portion and may be provided with a cloth or the like in which medicine has been soaked. The medicine placement portion is located on the front surface side of the first housing 6 facing the airflow direction F1, and is made of a flat resin to which a cloth can be attached. The medicine arrangement portion may be provided with a vent hole.

For example, in the above embodiment, the first casing 6 and the second casing 8 are fitted to each other, and the blower unit 2 and the power supply unit 3 are engaged with each other. However, the present invention is not limited to this, and for example, a screw member or the like may be used to engage the blower unit 2 with the power supply unit 3.

(embodiment 5)

Fig. 15 is a front view of an air blower 200 for air-conditioning clothes according to an embodiment of the present invention. The blower 200 for air-conditioning clothes is used by being attached to the air-conditioning clothes 100. The blower 200 for air-conditioning clothes is inserted into a mounting hole formed in the air-conditioning clothes 100 and is mounted on the air-conditioning clothes 100. In embodiment 5, the air-conditioning clothes blower 200 includes an axial-flow blower and a centrifugal blower. Hereinafter, an example of a case where the air-conditioning clothes blower 200 is an axial flow blower is described.

The air-conditioning clothes blower 200 includes a main body 202 having a fan 204 and a motor 206 for driving the fan 204. The air-conditioning clothes blower 200 includes a rear frame 203 attached from the rear side of the main body 202. The blower 200 for air-conditioning clothes sandwiches the air-conditioning clothes 100 between the main body 202 and the back frame 203 as described later.

The main body 202 includes: the fan 204 and a battery 208 that supplies electric power to a motor 206 that drives the fan 204. The battery 208 is constituted by a storage battery, for example. One or a plurality of batteries 208 may be disposed on the main body 202.

The battery 208 is disposed outside the outer diameter of the fan 204 in front view. The battery 208 is disposed outside the outer diameter of the fan 204 in the direction of the rotation shaft 207 of the fan 204. That is, the battery 208 is disposed at the outer side of the airflow generated in the case where the fan 204 rotates. Thus, the air flow generated by the rotation of the fan 204 is not obstructed, and the air can be efficiently sent into the air-conditioning clothes.

The battery 208 may be disposed outside the outer diameter of the fan 204 in the direction of the rotation shaft 207. The battery 208 may be arranged in the longitudinal direction close to the outer periphery of the fan 204. By disposing the battery 208 further outside than the outer diameter of the fan 204, when the air-conditioning clothes blower 200 is mounted on the air-conditioning clothes 100, the center of gravity at a predetermined distance from the rotary shaft 207 is located downward, and the air-conditioning clothes blower 200 is stabilized.

Further, when the fan 204 is rotated, it is possible to favorably suppress: the air-conditioning clothes blower 200 itself is rotated in a state of being attached to the air-conditioning clothes 100 as the fan 204 is rotated.

A fan shield 212 is disposed on the front side of the fan 204. The fan shield 212 is disposed on the front side of the fan 204. In the example of fig. 15, the fan shield 212 is formed to be air permeable by a frame extending radially from the center.

An exhaust port 210 is formed in front of the fan 204. The exhaust port 210 discharges the gas pushed forward by the rotation of the fan 204.

Fig. 16 is a diagram illustrating an example of the structure of the blower 200 for air-conditioning clothing according to the present embodiment, as viewed from the side. Fig. 16(a) is an example of a side view of the blower 200 for air-conditioning clothes according to the present embodiment. The main body 202 has a through hole 220 in the vicinity of the substantial center. The fan 204 and the motor 206 are disposed in the through hole 220. A fan shield 212 is disposed in front of the through hole 220. The fan shield 212 is detachably engaged with the main body 202.

The main body 202 includes an operation switch 214. The operation switch 214 inputs a signal to a control unit 222 that controls the driving of the motor 206. For example, the operation switch 214 includes: a switch for switching ON/OFF of the motor 206, and a switch for switching the rotational speed of the motor 206.

The operation switch 214 and the control unit 222 are connected by an electric wire or the like in the main body 202. That is, the wires are hidden from being exposed to the outside of the main body 202, and thus damage to the wires due to the movement of the wearer of the air-conditioning garment 100 can be avoided satisfactorily.

The back frame 203 is detachably engaged with the back side of the main body 202. The back frame 203 has a suction port 221 having substantially the same size as the through hole 220. Fig. 16(b) is a side sectional view of an air-conditioning clothes blower 200 according to the present embodiment.

When the back frame 203 is engaged with the main body 202, a suction port 221 is provided on the rear side of the through hole 220. The inner peripheral surface of the back frame 203 is configured to gradually expand rearward. The suction port 221 has an inner diameter gradually increasing rearward in the gas flow direction. Thus, when the fan 204 is rotated, the resistance when the air is sucked can be reduced.

In contrast, the inner diameter of the inner peripheral surface of the rear frame 203 may be substantially the same without gradually increasing.

Fan shield 212 engages with main body 202 at the inner circumferential surface of through hole 220. Fan shield 212 further includes engaging portion 212 a. The engaging portion 212a engages with the inner peripheral side surface of the through hole 220. The fan 204 is integrally formed with the rotary shaft 207. The length (n1) of the fan 204 from the rotation shaft 207 is shorter than the length (n2) from the rotation shaft 207 to the inner circumferential surface of the engagement portion 212 a. With n1< n2, when the fan 204 is rotating, the fan 204 can be prevented from contacting the engaging portion 212 a.

Preferably, the inner peripheral surface of the engagement portion 212a and the inner peripheral surface of the through hole 220 that is not engaged with the engagement portion 212a may be configured to be substantially the same plane. The inner peripheral surface of the through hole 220 engaged with the engaging portion 212a has a larger inner diameter than the other inner peripheral surfaces of the through hole 220, and is configured to expand outward. When the fan shield 212 is engaged with the main body 202, the engaging portion 212a engages with the inner peripheral surface of the through hole 220 that is expanded outward. In the state where both are engaged, the difference in height between the inner peripheral surface of the engaging portion 212a and the other inner peripheral surface of the through hole 220 is minimized. Accordingly, in the state where the fan shield 212 is engaged with the main body 202, the work efficiency of disposing the fan 204 in the through hole 220 can be improved.

Fig. 17 is a diagram showing an example of the fan shield 212 according to the present embodiment. Fig. 17(a) is a front view of the fan shield 212. The fan shield 212 is formed of resin or the like, and is constituted by a frame extending radially from the center. The through hole 220 is configured to be plugged from the front side. In the example of fig. 17(a), the front view is circular. The length from the center to the outer edge is longer than the inner diameter of the through hole 220.

Fig. 17(b) is a side view of the fan shield 212. The fan shield 212 includes the engaging portion 212a that engages with the inner peripheral surface of the through hole 220 as described above. The fan shield 212 is provided with an exhaust port 210 at the front side in the gas flow direction, continuously to the engagement portion 212 a.

The inner periphery of the exhaust port 210 is configured to expand outward from the inner periphery of the engagement portion 212 a. The exhaust port 210 is formed continuously from the engagement portion 212a on the front side in the gas flow direction. The inner circumferential surface of the exhaust port 210 is configured to expand outward. Thereby, resistance to the situation of the exhaust gas can be reduced.

Fig. 18 is a diagram showing an example of the structure of the blower 200 for air-conditioning clothing according to the present embodiment. Fig. 18(a) is a front view of the blower 200 for air-conditioning clothes. Three batteries 208 are disposed outside the outer diameter of the fan 204 of the body portion 202. The battery 208 is electrically connected to the motor 206 through an electric wire or the like in the main body 202. The wires connecting the motor 206 and the battery 208 are hidden within the body portion 202.

Fig. 18(b) is a sectional view a-a' of the blower 200 for air-conditioning clothes. The main body 202 includes a first receiving portion 224a that engages with an engaging portion 212a of the fan shield 212. The first receiving portion 224a is expanded to the outside of the inner circumference of the through hole 220. Thus, when the engaging portion 212a is engaged with the first receiving portion 224a, the inner peripheral surface of the engaging portion 212a has substantially the same diameter as the inner peripheral surface of the through hole 220.

The main body 202 includes a second receiving portion 224b that engages with the rear frame 203. The second receiving portion 224b is provided on the rear surface side of the main body portion 202 outside the through hole 220. The second receiving portion 224b is formed by being recessed from the rear end surface outside the through hole 220. Accordingly, when the fan shield 212 is engaged with the main body 202, the inner circumferential surface of the through hole 220 and the inner circumferential surface of the engaging portion 212a are substantially flush with each other, and the fan 204 can be disposed in the through hole 220 satisfactorily.

Fig. 19 is a diagram showing an example of the structure of the rear frame 203 according to the present embodiment. Fig. 19(a) is a front view of the back frame 203. The back frame 203 has a substantially circular shape. The back frame 203 has a substantially circular suction port 221 at the center. Suction port 221 is formed to have substantially the same inner diameter as through-hole 220.

Fig. 19(b) is a side view of the back frame 203. The suction port 221 is configured to gradually expand in inner diameter toward the rear side in the gas flow direction. The inner circumferential end of suction port 221 is configured to gradually expand outward toward the rear. Thus, the resistance to the gas suction can be reduced.

Fig. 20 is a block diagram showing an example of the functional structure of the blower 200 for air-conditioning clothes according to the present embodiment. The air-conditioning-clothes blower 200 includes a control unit 222 that controls the driving of the motor 206. The operation switch 214 inputs a signal to the control unit 222 in response to an operation by a user. The control unit 222 controls the motor 206 in response to a signal input from the operation switch 214.

The control unit 222 further includes: a drive control unit 222a for performing ON/OFF switching of the motor 206, and an operation control unit 222b for performing rotational speed switching of the motor 206.

The drive control unit 222a starts driving the motor 206 when a signal for driving the motor 206 is input from the operation switch 214. When a signal for stopping the driving of the motor 206 is input from the operation switch 214, the drive control unit 222a stops the driving of the motor 206.

The operation control unit 222b is a processing unit that controls switching of the rotation speed of the motor 206 in a state where the motor 206 is driven. The operation control unit 222b sets the rotation speed of the motor 206 to any one of three stages set in advance, for example. By switching the rotation speed of the motor 206, the amount of gas discharged into the air-conditioning garment 100 can be adjusted.

The control unit 222 may be incorporated in the operation switch 214, or may be incorporated in the motor 206, differently from this. The operation switch 214, the control unit 222, and the motor 206 are disposed in the main body 202. Therefore, the electric wires connected to these can be hidden in the main body 202, and therefore, the electric wires can be prevented from being worn out along with the body movement of the user wearing the air-conditioning garment 100.

Fig. 21 is a diagram showing an example of the air-conditioning garment 100 to which the blower 200 for air-conditioning garment of the present embodiment is attached. Fig. 21(a) is a rear view of the air-conditioning garment 100 in a state where the blower 200 for air-conditioning garment is attached. The air-conditioning garment 100 includes a mounting hole in a lower portion of a back surface side. In the drawings, although the case where a plurality of mounting holes are provided is illustrated, one mounting hole may be provided.

When the motor 206 of the air-conditioning clothes-use blower 200 is driven, air is sucked from the outside of the air-conditioning clothes 100 and discharged to the inside of the air-conditioning clothes 100. This promotes the evaporation of sweat from the wearer wearing the air-conditioning garment 100, and suppresses the rise in body temperature of the wearer.

The air-conditioning garment 100 includes a constriction limiting section 104 (ventilation adjusting section) near the boundary between the shoulder and the sleeve. The constriction limiting portion 104 (ventilation adjusting portion) may be formed by sewing an elastic body such as a rubber band into the sleeve portion. Alternatively, the sleeve portion may be wound with an inner circumference width adjustment cord. The constriction part 104 (ventilation adjusting part) has a function of adjusting the amount of air flowing from the body part of the air-conditioning garment 100 to the sleeve part.

The inner peripheral width of the sleeve portion is narrowed by the constriction of the constriction portion 104 (ventilation adjustment portion), and the amount of air flowing from the body portion into the sleeve portion is reduced. When the air-conditioning clothes treating blower 200 is driven, air flows into the air-conditioning clothes 100 by the air-conditioning clothes treating blower 200, and the volume of air inside the air-conditioning clothes 100 increases, and the air-conditioning clothes 100 expands. When the constriction portion 104 (ventilation adjustment portion) constricts, the inner peripheral width of the sleeve portion is narrowed, so that the inflow amount of air into the sleeve portion can be suppressed, and the expansion of the sleeve portion due to air can be suppressed. This prevents the movement of the arms of the wearer from being hindered by the inflated sleeves.

Fig. 21(b) is a view showing an example of an installation state of the blower 200 for air-conditioning clothes. The main body 202 and the back frame 203 are configured to sandwich the air-conditioning garment 100. The back frame 203 expands the end portion outward on the rear side in the gas flow direction.

The end of the back frame 203, which is expanded outward, and the main body 202 sandwich the end of the mounting hole of the air-conditioning garment 100 when the back frame 203 is engaged with the main body 202. That is, when the main body 202 is disposed inside the air-conditioning garment 100 and the back frame 203 is disposed outside the air-conditioning garment 100 and the back frame 203 is engaged with the main body 202, the main body 202 and the back frame 203 are engaged with each other through the mounting hole of the air-conditioning garment 100. Thereby, the blower 200 for air-conditioning clothes is attached to the air-conditioning clothes 100.

Fig. 22 is a diagram showing an example of the air-conditioning clothes blower 200 having a structure different from that of the air-conditioning clothes blower 200. The main body 202 is formed in a dome shape in a cross-sectional view, and includes a fan 204, a motor 206, and a battery 208. The main body 202 is formed in a tapered shape on the front side in the airflow direction F1.

The battery 208 is disposed further rearward than the fan 204 in the flow direction of the gas. Alternatively, the battery 208 may be disposed outside the outer diameter of the fan 204 from the rotating shaft 207.

The back frame 203 engages with the back surface side of the main body 202. When the back frame 203 is engaged with the main body 202, the two are engaged with each other through the mounting hole of the air-conditioning garment 100. The main body 202 and the rear frame 203 are engaged with each other with a cloth interposed therebetween. Thereby, the blower 200 for air-conditioning clothes is attached to the air-conditioning clothes 100.

Fig. 23 is a diagram showing an example of the structure of the back frame 203. In the illustrated example, the rear frame 203 includes a screw portion that engages with the main body 202. The back frame 203 includes a holding portion 230 for holding a peripheral portion of the mounting hole of the air-conditioning garment 100.

The holding portion 230 holds the peripheral edge portion of the mounting hole of the air-conditioning garment 100 between the corresponding portions of the main body 202 when the main body 202 is engaged with the rear frame 203.
