Description

Technical Field

[0001] The present invention relates to a cooling device for clothing, which is configured with a shell and a Peltier element, cooling fins formed on one side of the Peltier element, heat dissipation fins formed on the opposite side of the one side, and an air supply fan for supplying air to the cooling fins and the heat dissipation fins. The cooling device is installed on clothing to cool the inside of the clothing. Background Art

[0002] In recent years, there have been many unpleasantly hot days throughout the year. On such hot days, as a countermeasure to prevent heat stroke, it is encouraged to frequently drink water and use appropriate air conditioning equipment.

[0003] However, due to the lack of air-conditioning equipment or insufficient cooling effect, workers working outdoors in the scorching heat, workers working in a stuffy indoor environment, and people entertaining, exercising, watching games, etc. under the scorching sun cannot use air-conditioning equipment to cool down.

[0004] Therefore, for those who seek to escape the heat, clothes with air conditioning functions have become popular, and in recent years, air-conditioning clothes equipped with air conditioning units utilizing Peltier elements have also been developed. One example thereof is disclosed in Patent Documents 1 and 2.

[0005] Patent document 1 is a heat exchange unit, which has a Peltier element installed on a partition plate that separates the inside of a garment from the outside of the garment, a first heat transfer member that conducts heat on one side of the Peltier element and a first fan that diffuses air that has exchanged heat through the first heat transfer member to the inside of the garment are provided on the inside of the garment on the inside of the garment on the partition plate, and a second heat transfer member that conducts heat on the other side of the Peltier element and a second fan that discharges air that has exchanged heat through the second heat transfer member to the outside of the garment are provided on the outside of the garment on the outside of the partition plate. The heat exchange unit is mounted on fabric of the garment.

[0006] Patent document 2 is a functional garment with an air conditioning unit, which introduces air into a flow path from an inlet arranged at the wearer's waist, cools the air introduced into the flow path using a Peltier element, and guides the cooled air to a belt-shaped outlet and discharges it to the center of the wearer's back or around the neck.

[0010] Patent Document 2: Japanese Patent Application Publication No. 2019-70215 Summary of the invention

[0011] Problem that the invention aims to solve

[0012] However, there are the following problems in Patent Documents 1 and 2. Patent Document 1 has a structure in which heat transfer members and fans are arranged in a row on the inside and outside of clothing via a Peltier element mounted on a partition plate, so the entire heat exchange unit is inevitably large-scaled.

[0013] Therefore, when people perform work or actions while wearing the clothing with the heat exchange unit of Patent Document 1, the heat exchange unit may hinder the work or the like, and there is a risk that physical activities may become difficult. Therefore, the clothing with the heat exchange unit is not easy to use.

[0014] Furthermore, in Patent Document 2, the flow path of air cooled by the Peltier element is arranged outside the fabric of the clothing, so when a person wearing functional clothing performs work or actions under the scorching sun on a hot summer day, the flow path of the cooled air is directly exposed to the scorching sun.

[0015] Therefore, even if the air introduced into the flow path from the inlet is cooled by the Peltier element, the flow path of the cooled air is heated by direct sunlight at a high outside air temperature, and there is a risk that the cool air may not reach the back or neck of the wearer.

[0016] The present invention is made to solve the above-mentioned problems, and its object is to provide a cooling device for clothing that is easy to use for people wearing the clothing and can efficiently transport cold air.

[0017] Technical means of solving problems

[0018] 14. The clothing cooling device of claim 13 wherein the cooling fins are configured to move air from one surface of the clothing to the other surface of the clothing, the cooling fins being arranged in the housing and the cooling fins being arranged in the housing. The cooling fins are configured to move air from one surface of the clothing to the other surface of the clothing, the cooling fins being arranged in the housing and the cooling fins being arranged in the housing. The cooling fins are configured to move air from one surface of the clothing to the other surface of the clothing, the cooling fins being arranged to move air from the other surface of the clothing to the other surface of the clothing.

[0019] According to this aspect, the clothing cooling device can be easily installed in or removed from the pocket of clothing by simply attaching and detaching the flange to the opening of the clothing. Therefore, when washing the clothing, the clothing cooling device can be easily attached and detached from the clothing, and the clothing cooling device is easy to use for the user.

[0020] In addition, the clothing cooling device is installed in the pocket of the clothing, and the cold air outlet of the clothing cooling device is arranged on the inner side of the clothing, so the cold air generated by the cooling fins is not easily affected by the heat of the external air side which is high in temperature under the scorching sun. For example, it can directly and efficiently supply air mainly to the parts of the body that want to be cooled, such as the neck, sweaty armpits and flanks, while maintaining a low temperature of about 10°C.

[0021] In the above aspect, it is preferable to include a reinforcing member for attaching the flange to the inner and outer peripheral surfaces.

[0022] According to this aspect, even when the wearer of the clothing equipped with the cooling device for clothing performs work or the like with large movements, it is possible to prevent the cooling device for clothing from falling out of the pocket due to the movement.

[0023] In the above-mentioned aspect, it is preferable that the air introduction port is formed on the surface of the housing on the same side as the cold air port to introduce air into the clothing (aspect A).

[0024] According to this form (form A), when the air introduced into the air inlet is in a state where the temperature is lower than that of the external air (the first usage environment), the air introduced into the air inlet is cooled to a lower temperature by the cooling fins and easily becomes sufficiently cool cold air.

[0025] Furthermore, when the wearer of clothing equipped with the clothing cooling device is in a harsh indoor environment (the second usage environment), for example, in an environment where dust or fumes are floating indoors or when working with equipment in an environment with high temperature and high humidity, by introducing air from the inside of the clothing into the air inlet, foreign matter other than the air in the indoor environment can be prevented from having an adverse effect on the clothing cooling device.

[0026] In the above-mentioned aspect, it is preferable that the air introduction port is formed on the surface of the housing on the same side as the heat dissipation port to introduce the outside air (aspect B).

[0027] According to this form (form B), when the temperature difference between the air on the outside air side and the air inside the clothing is in a relatively small state of, for example, several degrees Celsius (the third usage environment), if the air inlet port introduces the air from the outside air side, the resistance caused by the air flowing toward the air inlet port can be suppressed to a smaller level compared to the case where the air is introduced from the inside of the clothing forming a roughly closed space.

[0028] Therefore, in the clothing cooling device, the air introduced into the air inlet by the air-sending blower can flow smoothly toward the Peltier element easily, and the cold air can also be sent from the cold air outlet with a smooth airflow.

[0029] In the above aspect, it is preferable to include a control unit, and by inverting the polarity of the direct current supplied to the Peltier element by the control unit, the action of the above (Aspect A) or (Aspect B) can be switched.

[0030] According to this form, when the clothing cooling device is used, in the presence of various usage environments such as the first usage environment to the third usage environment mentioned above, the clothing cooling device can flexibly perform the above-mentioned (form A) and (form B) functions according to the surrounding environment.

[0031] Furthermore, after the polarity of the DC current in the Peltier element is reversed through the operation of the control unit, the use mode of the clothing cooling device can be simply switched between the above-mentioned (mode A) effect and the above-mentioned (mode B) effect by simply reversing the direction of the clothing cooling device housed in the pocket of the clothing relative to the inside of the clothing and the outside air side.

[0032] In the above aspect, it is preferred that the housing is inserted into a pocket formed on clothing, and at least one surface of the pocket, either on the clothing side or on the outside air side, is formed with a mesh cloth.

[0033] According to this aspect, if the mesh cloth is formed on the inner side of the pocket, the air in the garment (internal air) can be introduced into the air inlet of the garment cooling device housed in the pocket through the mesh cloth.

[0034] Furthermore, if the mesh cloth is formed on the external air side of the pocket, the air on the external air side can be introduced into the air introduction port of the clothing cooling device accommodated in the pocket through the mesh cloth.

[0035] In addition, if the mesh is formed on both the inner side of the pocket and the outer air side, the air introduced into the air inlet can be directed to both the inner air and the outer air. Thus, the clothing cooling device can cope with the situation that the effect of (form A) and the effect of (form B) described above are selectively distinguished.

[0036] Effects of the Invention

[0037] Therefore, according to the clothing cooling device of one aspect of the present invention, excellent effects such as good usability for the wearer of the clothing and the ability to efficiently send cool air to the wearer are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Hereinafter, embodiments of the cooling device for clothing of the present invention will be described in detail with reference to the accompanying drawings. The cooling device for clothing of the present invention is a device for cooling the hot body of a person wearing clothing.

[0053] The clothing cooling device is inserted into a pocket formed on the clothing and is used by people who need cool air, such as workers working outdoors in hot summer, workers working in a stuffy indoor environment, people doing entertainment, sports, watching games, etc. under the scorching sun.

[0054] Regarding clothing, in addition to work clothes, there are also multi-purpose tops, vests, pants, etc. that can be worn for various purposes such as entertainment, leisure, competitions, activities, sports, running, cycling, etc.

[0055] Figure 1 It is a front view showing the cooling device for clothing according to the embodiment. Figure 2 for Figure 1 The side view observed from the A direction, Figure 1 The side view observed from the B direction is shown in Figure 3 , Figure 1 The side view observed from the C direction is shown in Figure 4 , Figure 1 The side view observed from the D direction is shown in Figure 5 , Figure 2 The enlarged view of the middle E is shown in Figure 6 . Figure 7 for Figure 1 An exploded perspective view of a cooling device for clothing is shown.

[0056] Furthermore, in the clothing cooling device 1 of this embodiment, Figure 1 The left and right direction in the figure is the short side direction S. Figure 1 The up-down direction in the figure is the long side direction L, to show Figure 1 The vertical direction T of the paper is the thickness direction, Figure 2 The following figures also follow Figure 1 In addition, the illustration of the power supply for the Peltier element 11 and the air supply fan 20 is omitted in each figure.

[0057] like Figure 1 to Figure 7 As shown, the clothing cooling device 1 includes a Peltier element 11 , cooling fins 13 , heat dissipation fins 14 , a control unit 15 , an air blower 20 , a housing 30 , etc. The Peltier element 11 (cooling module 10 ) is disposed in the housing 30 .

[0058] The clothing cooling device 1 has a power source (not shown) for supplying power to the Peltier element 11 and the air blower 20 . In this embodiment, the power source provided separately from the housing 30 can be electrically connected to the Peltier element 11 , the control unit 15 and the air blower 20 .

[0059] The housing 30 is formed in a substantially flat plate shape by butting the upper member 30A and the lower member 30B against each other and joining them in a state where there is an internal space. Figure 1 The outer periphery of the upper side in the vertical direction is arc-shaped, and the other side in the opposite long side direction L ( Figure 1 The outer edges of the two sides of the long side L are straight and the outer edges of the two sides of the short side S ( Figure 1 A shape connected by a straight outer edge (in the left and right directions).

[0060] like Figure 7 As shown, the air supply fan 20 is disposed in the housing 30 and is arranged on one side of the long side direction L ( Figure 7 In the present embodiment, the air supply fan 20 is a multi-blade fan (Scirocco fan) which is a type of centrifugal fan.

[0061] A Scirocco blower is a roughly cylindrical blower with a plurality of blades arranged in a ring shape along the circumference of a rotating central axis, and blows the wind sucked along the central axis outward from between the rotating blades. In addition to the Scirocco blower, the blower may also be a propeller blower (axial flow), a turbine blower, etc.

[0062] The housing 30 has an air inlet 31 formed by opening a portion of the upper surface 30Aa of the upper member 30A. The air inlet 31 is an opening for introducing air into the air supply fan 20 and is arranged on one side in the longitudinal direction L ( Figure 1 The outer periphery (upper side in the up and down direction).

[0063] In addition, the housing 30 is provided with a first air supply port 42 and a second air supply port 45 in opposite directions of the housing 30 (upper member 30A, lower member 30B). The first air supply port 42 is formed by opening a portion of the upper member 30A of the housing 30, and the second air supply port 45 is formed by opening a portion of the lower member 30B of the housing 30.

[0064] That is, the first air supply port 42 is formed on the same upper surface 30Aa side of the upper member 30A as the air inlet port 31 in the thickness direction T of the housing 30 so as to be substantially flush with the upper surface 30Aa. Figure 2 to Figure 5As shown, the second air supply port 45 is formed on the lower surface 30Ba side of the lower member 30B on the opposite side from the air inlet port 31 in the thickness direction T of the housing 30 so as to be spaced apart from the lower surface 30Ba by having a height difference (step difference) with the lower surface 30Ba.

[0065] The first air supply port 42 has a first flange 43 formed around it. In addition, the second air supply port 45 has a second flange 46 formed around it. The internal space of the housing 30 is connected to the air inlet 31, the first air supply port 42 and the second air supply port 45, and the air flowing in from the air inlet 31 can flow in the housing 30 and flow out from the first air supply port 42 and the second air supply port 45.

[0066] Next, the Peltier element 11 will be described. Figure 8 1 is an explanatory diagram showing a Peltier element in a clothing cooling device according to an embodiment. Figure 7 and Figure 8 As shown, the Peltier element 11, the cooling fins 13 and the heat dissipation fins 14 together constitute the cooling module 10 and are disposed in the housing 30 and arranged on the other side of the long side direction L ( Figure 7 That is, the cooling module 10 is sandwiched between the image Figure 1 to Figure 5 As shown in the figure, it is arranged in a state between the first air supply port 42 and the second air supply port 45 which are arranged in opposite directions to each other.

[0067] The Peltier element 11 is a plate-shaped semiconductor thermoelectric element. When a direct current is supplied to the Peltier element 11, Figure 8 As shown, the flat plate portion 12 of the Peltier element 11 absorbs heat (cools) at one surface 12a and generates heat (heats) at the other surface 12b due to the Peltier effect.

[0068] The cooling module 10 has cooling fins 13 formed on one side 12a sandwiching the Peltier element 11, and heat dissipation fins 14 formed on the other side 12b (opposite side) opposite to the one side 12a. The cooling module 10 is electrically connected to a control unit 15 capable of reversing the direction of the direct current supplied to the Peltier element 11.

[0069] In the cooling module 10, when current is supplied to the Peltier element 11 in one direction, the fins formed on the one surface 12a side become the cooling fins 13, and the fins formed on the other surface 12b side become the heat dissipation fins 14. When the control unit 15 is operated in this state to reverse the direction of the direct current supplied to the Peltier element 11, the current supplied to the Peltier element 11 changes to the other direction opposite to the one direction.

[0070] In this case, the fins that were originally cooling fins 13 in one direction become heat dissipation fins 14, and the fins that were originally heat dissipation fins 14 in one direction become cooling fins 13. When the direction of the DC current is reversed, the cooling surface and the heating surface are switched in the flat plate portion 12 of the Peltier element 11.

[0071] The clothing cooling device 1 delivers the air AR introduced into the housing 30 from the air inlet 31 into the cooling module 10 by the air supply fan 20, thereby discharging cold air passing through the cooling fins 13 from the cold air outlet and discharging hot air passing through the heat dissipation fins 14 from the heat dissipation outlet.

[0072] At this time, there is a situation in which the air AR introduced into the air introduction port 31 is introduced from the inner side ( Fig. 9 and Fig.10 The first case (first use example) of introducing the inner side 70in of the garment in the first embodiment and the outer side 70in of the garment 70 opposite to the wearer's body through the garment 70 ( Fig. 9 and Fig.10 The second situation (second usage example) in which the external air side 70out) is introduced.

[0073] Fig. 9 Schematic diagram showing the first use case of the clothing cooling device of the embodiment. When the clothing cooling device 1 is used in the first use case, the air inlet 31 is formed on the upper surface 30Aa of the upper member 30A on the same side as the cold air outlet (first air supply outlet 42) in the thickness direction T of the shell 30, and air AR is introduced from the inner side of the clothing 70 (inside of the clothing).

[0074] That is, Fig. 9 As shown, the first air supply port 42 is a cold air port for conveying the air AR introduced from the air introduction port 31 by the air supply fan 20 and discharging the cold air CF after passing through the cooling fins 13 to the inside of the garment 70 (the inside 70 in of the garment).

[0075] On the other hand, the second air outlet 45 serves as a heat dissipation outlet for conveying the air AR introduced from the air inlet 31 by the air blower 20 and discharging the hot air HF after passing through the heat dissipation fins 14 to the outside of the garment 70 (to the outside air side 70out).

[0076] Fig.10 Schematic diagram showing a second use case of the clothing cooling device of the embodiment. When the clothing cooling device 1 is used in the second use case, the air inlet 31 is formed on the upper surface 30Aa of the upper member 30A on the same side as the heat dissipation port (first air supply port 42) in the thickness direction T of the housing 30, and air AR is introduced from the outside (external air side) of the clothing 70.

[0077] That is, Fig.10 As shown, the first air outlet 42 is a heat dissipation outlet for conveying the air AR introduced from the air inlet 31 by the air blower 20 and discharging the hot air HF after passing through the heat dissipation fins 14 to the outside of the garment 70 (the outside air side 70out).

[0078] On the other hand, the second air supply port 45 is a cold air port for conveying the air AR introduced from the air introduction port 31 by the air supply fan 20 and discharging the cold air CF after passing through the cooling fins 13 to the inside of the garment 70 (the inside 70 in of the garment).

[0079] As described above, when the clothing cooling device 1 is used in the first use case, the cold air outlet is the first air supply outlet 42, and the cold air CF is discharged from the first air supply outlet 42. In addition, when the clothing cooling device 1 is used in the second use case, the cold air outlet is the second air supply outlet 45, and the cold air CF is discharged from the second air supply outlet 45.

[0080] At this time, if the first air outlet 42 used in the first use case is Figure 6 As shown, the first air hole 44 is formed around the wall portion surrounding the first air supply port 42 near the first flange 43 so as to be in contact with the space inside the clothing 70, so that the cold air CF can be diffused and supplied to the space inside the clothing 70.

[0081] Similarly, if the second air outlet 45 used in the second use example is Figure 6 As shown, the second air hole 47 is formed around the wall portion surrounding the second air supply port 45 near the second flange 46 so as to be in contact with the space inside the clothing 70, so that the cold air CF can be diffused and supplied to the space inside the clothing 70.

[0082] Next, for convenience of description, a case where the clothing cooling device 1 used in the second usage example is attached to the clothing 70 will be described to describe the clothing 70 to which the clothing cooling device 1 is attached.

[0083] Fig.11 1 is an explanatory diagram showing a pocket formed on a garment of a cooling device for garment according to an embodiment of the present invention. Fig.11 The FF cross-section diagram is shown in Fig.12 and Fig.13 . Fig.14 This is a diagram showing a state in which the cooling device for clothing according to the embodiment is put into a pocket of clothing and used in a second usage example.

[0084] like Figure 11 to Figure 14As shown, a pocket 71 is formed on the garment 70. When the garment 70 is a garment worn on the upper body such as a coat or a vest, the pocket 71 is arranged in the garment 70 mainly corresponding to the neck or the sweaty armpits and flanks.

[0085] Furthermore, when the garment 70 is a garment worn on the lower body such as pants, the pocket 71 is arranged in a portion of the garment 70 mainly corresponding to the vicinity of the thigh root or the like.

[0086] Here, the arrangement position of the pocket 71 provided on the garment 70 is briefly described. A human body exposed to a hot environment is at risk of heat stroke due to the heat, and also has a serious adverse effect on the autonomic nerves. Therefore, as a preventive measure, it is first important to cool the blood flowing in the artery to the brain and promote sweating to maintain normal body temperature regulation function.

[0087] To effectively cool the blood flowing to the brain, it is considered advisable to cool the arteries in the neck, armpits and thighs.

[0088] In the case of a neck stiffness, in addition to the hairline at the back of the neck, there is a carotid artery, especially near the left and right sides of the throat. If the part that touches the artery is cooled by cold air or the like to cool the blood, the cooled blood will flow through the whole body, thereby lowering the body temperature.

[0089] In addition, the armpit is the part where the thermometer is placed, and there are arteries. The arteries in the armpit are located toward the arm, and if the blood in the arteries in the armpit or the arteries in the soft part near the inner side of the upper arm is cooled, the cooled blood will flow through the whole body, thereby lowering the body temperature.

[0090] In addition, by blowing cold air on the armpits, the surface temperature of the skin will be lowered due to the vaporization heat brought by the sweat from the armpits, thereby also obtaining a cool feeling. In the case of the thigh root, there is a thick artery to the foot at a position equivalent to the inner third of the line connecting the front surface of the thigh, the lumbar vertebrae and the crotch. In particular, when the blood in the thick artery is cooled, the cooled blood will flow through the whole body. In this way, the body temperature can be lowered.

[0091] In this view, Fig.14 As shown, pockets 71 are formed in the garment 70 at the portion corresponding to the neck and armpits and at the portion corresponding to the thighs, so as to cool the arteries at the neck and armpits and, if necessary, the arteries at the thighs.

[0092] Then, the clothing cooling device 1 accommodated in these pockets 71 sends the cold air CF discharged from the cold air outlet directly or in a close form to the neck, armpits and thighs to cool the body of the wearer of the clothing 70.

[0093] The pocket 71 inserts and stores the housing 30 main body constituting the clothing cooling device 1 into the pocket 71. Specifically, when the clothing cooling device 1 is used in the second usage example, the clothing cooling device 1 is as shown in FIG. Fig.10 and Fig.12 As shown in FIG. 1 , the air inlet 31 and the first air outlet 42 are oriented toward the outside air side 70out on the housing 30 ( Fig.12 The second air outlet 45 is directed toward the inner side of the garment by 70 inches ( Fig.12 The configuration on the right side of the figure) is housed in pocket 71.

[0094] Furthermore, when the clothing cooling device 1 is used in the first usage example, the clothing cooling device 1 is used with Fig.10 The housing 30 shown in the figure is oriented in the opposite direction, with the air inlet 31 and the first air outlet 42 facing the inner side of the garment 70 ( Fig. 9 The second air outlet 45 is directed toward the outside of the garment 70 ( Fig.10 The configuration of the external air side 70out) is housed in the pocket 71.

[0095] The inner and outer sides of the pocket 71 are respectively Fig.12 As shown, a portion of the garment 70 is opened to form an opening 72. The opening 72 is sized to allow the first air outlet 42 and the second air outlet 45 to pass through the housing 30 of the garment cooling device 1 inserted into the pocket 71.

[0096] The outer edge of the opening 72, that is, the inner and outer peripheral surfaces 73, are formed by a high rigidity portion 77 made of a material (e.g., leather, rubber, resin, etc.) having higher rigidity than the fabric 75 (cloth, etc.) of the garment 70 having a certain degree of flexibility.

[0097] In addition, the surface of the pocket 71, especially the portion where the air inlet 31 is arranged, is formed by a mesh 74. In this embodiment, Fig.12 As shown, the mesh 74 is formed on the outside of the pocket 71 ( Fig.12 The outside air side 70out) and the inside of the pocket 71 ( Fig.12 70in) on the inside of the garment.

[0098] That is, when the clothing cooling device 1 is used in the second use example, Fig.12 As shown, the outer side (outside air side 70 out ) of the pocket 71 is formed by a mesh 74 , and the air AR formed by the outside air is introduced from the outside air side 70 out through the mesh 74 into the air introduction port 31 in the pocket 71 .

[0099] On the other hand, when the clothing cooling device 1 is used in the first usage example, the inner side of the pocket 71 (reference Fig.12 The right side of the pocket 71 is formed by a mesh cloth 74, and the air AR in the garment 70 is introduced into the air inlet port 31 in the pocket 71 from the inner side 70in of the garment through the mesh cloth 74.

[0100] In the second use example of the clothing cooling device 1 accommodated in the pocket 71, as shown in FIG. Fig.12 As shown, after the second flange 46 of the second air supply port 45 serving as a cold air outlet is inserted into the opening 72 of the garment 70 located inside the pocket 71 , a reinforcing member 76 is installed between the inner and outer peripheral surfaces 73 of the opening 72 and the second flange 46 .

[0101] The reinforcing member 76 is a member such as a rubber gasket that suppresses relative play (gap) between the inner and outer peripheral surfaces 73 and the second flange 46 and is detachably connected to the second flange 46. Fig.12 As shown, after the first flange 43 of the first air supply port 42 serving as a heat dissipation outlet is inserted into the opening 72 of the garment 70 located outside the pocket 71 in the pocket 71, a reinforcing member 76 is installed between the inner and outer peripheral surfaces 73 of the opening 72 and the second flange 46.

[0102] In this way, the clothing cooling device 1 is attached to the clothing 70 in the pocket 71 by means of the reinforcing member 76 .

[0103] Furthermore, in the embodiment, when the clothing cooling device 1 of the second use example is accommodated in the pocket 71, the first flange 43 is inserted into the opening 72 of the clothing 70 located outside the pocket 71 and the reinforcing member 76 is installed between the inner and outer peripheral surfaces 73 and the first flange 43.

[0104] But it can also be like Fig.13 As shown, the first flange 43 of the clothing cooling device 1 housed in the pocket 71 is not fixed to the outside of the pocket 71, and the first flange 43 and the pocket 71 are in a relatively free state.

[0105] In addition, if Fig.13 As shown, the second flange 46 can be inserted between the inner and outer peripheral surfaces 73 of the opening 72 and the high rigidity portion 77 of the inner and outer peripheral surfaces 73 to be sandwiched between the two, thereby connecting the clothing cooling device 1 in the pocket 71.

[0106] In addition, when the clothing cooling device 1 of the first use example is accommodated in a pocket 71, after the first flange 43 of the first air supply port 42 serving as a cold air outlet is inserted into the opening 72 of the clothing 70 located inside the pocket 71, it is installed between the inner and outer peripheral surfaces 73 of the opening 72 and the high rigidity portion 77.

[0107] In this way, the clothing cooling device 1 is attached to the clothing 70 in the pocket 71 by means of the reinforcing member 76 .

[0108] Next, the operation and effects of the clothing cooling device 1 according to the present embodiment will be described.

[0109] The clothing cooling device 1 of the present embodiment is a clothing cooling device which is installed on clothing 70 to cool the inside of clothing 70 by configuring a housing 30 and configuring a Peltier element 11 in the housing 30, a cooling fin 13 formed on one side 12a of a flat plate portion 12 of the Peltier element 11, a heat dissipation fin 14 formed on the other side 12b opposite to the one side 12a, and an air supply fan 20 for supplying air to the cooling fin 13 and the heat dissipation fin 14. The clothing cooling device is characterized in that an air inlet 31 for the air supply fan 20 to introduce air AR (outside air) is provided on the housing 30, and an air inlet 31 for the air supply fan 20 to introduce air AR (outside air) is provided in the opposite direction in the thickness direction T of the housing 30. The cold air outlet (the first air supply outlet 42 in the first use case and the second air supply outlet 45 in the second use case) for discharging the cold air CF after the supercooling fins 13 and the heat dissipation outlet (the second air supply outlet 45 in the first use case and the first air supply outlet 42 in the second use case) for discharging the hot air HF after passing through the heat dissipation fins 14, the cold air outlet having a flange (the first flange 43 of the first air supply outlet 42 in the first use case and the second flange 46 of the second air supply outlet 45 in the second use case), and the flange (the first flange 43 or the second flange 46) is freely and detachably connected to the inner and outer peripheral surfaces 73 of the opening 72 formed on the clothing 70.

[0110] With this feature, the clothing cooling device 1 can be easily installed in or removed from the pocket 71 of the clothing 70 by simply attaching and detaching the flange (the first flange 43 or the second flange 46) to the opening 72 of the clothing 70. Therefore, when washing the clothing 70, the clothing cooling device 1 can be easily attached and detached from the clothing 70, and the clothing cooling device 1 is easy to use for its user.

[0111] In addition, the clothing cooling device 1 is installed in the pocket 71 of the clothing 70, and the cold air outlet of the clothing cooling device 1 is arranged on the inner side 70in of the clothing 70, so the cold air CF generated by the cooling fins 13 is not easily affected by the heat of the external air side 70out which is high in temperature under the scorching sun. For example, it can directly and efficiently supply air mainly to the parts of the body that want to be cooled, such as the neck, sweaty armpits and flanks, while maintaining a low temperature of about 10°C.

[0112] Therefore, according to the clothing cooling device 1 of the present embodiment, excellent effects are achieved, such as good usability for the wearer of the clothing 70 and the ability to efficiently deliver the cool air CF to the wearer.

[0113] Furthermore, the clothing cooling device 1 of the present embodiment is characterized in that it includes a reinforcing member 76 for attaching the flange (the first flange 43 or the second flange 46 ) to the inner and outer peripheral surfaces 73 of the opening 72 .

[0114] This feature can prevent the cooling device 1 from falling out of the pocket 71 due to the movement, even when the wearer of the garment 70 equipped with the cooling device 1 performs work with large movements.

[0115] Furthermore, the clothing cooling device 1 of the present embodiment is characterized in that, in the case of the first use example, the air inlet 31 is formed like Fig. 9 As shown, the air AR in the garment 70 is introduced into the upper surface 30Aa of the upper member 30A of the casing 30 which is located on the same side as the cold air outlet serving as the first air outlet 42 .

[0116] With this feature, when the air AR introduced into the air inlet 31 is in a state where the temperature is lower than that of the external air side 70out (the first usage environment), the air AR introduced into the air inlet 31 is cooled to a lower temperature by the cooling fins 13 and easily becomes sufficiently cool cold air CF.

[0117] That is, when the wearer of the garment 70 equipped with the garment cooling device 1 is located at the outside air side 70out under the hot sun in midsummer, the temperature of the inside 70in of the garment may be lower than the temperature of the outside air side 70out. When the Peltier element 11 absorbs heat from the introduced air AR in the form of heat absorption capacity during heat exchange, if it is desired to absorb heat with the same amount of heat as the heat absorbed by the high-temperature air AR on the outside air side 70out, if the Peltier element 11 is used to exchange heat with the low-temperature air AR on the inside 70in of the garment, the introduced air AR can be cooled at a lower temperature.

[0118] Therefore, when the temperature of the inner side 70in of the clothing is lower than the temperature of the external air side 70out, if the air inlet port 31 introduces air AR from the inner side 70in of the clothing, the clothing cooling device 1 can deliver cold air CF cooled to a lower temperature by the cooling fins 13 compared to introducing air AR from the external air side 70out.

[0119] Furthermore, when the wearer of the garment 70 equipped with the garment cooling device 1 is in a harsh indoor environment (the second usage environment), for example, in an environment where dust or fumes are floating indoors or when working with equipment in an environment with high temperature and high humidity, if the air AR on the inside 70in of the garment is introduced into the air inlet port 31, foreign matter other than the air AR in the indoor environment can be prevented from having an adverse effect on the garment cooling device 1.

[0120] Furthermore, the clothing cooling device 1 of the present embodiment is characterized in that, in the case of the second usage example, the air inlet 31 is formed like Fig.10 As shown, the upper surface 30Aa of the upper member 30A of the housing 30 is formed on the same side as the heat dissipation port serving as the first air supply port 42 to introduce the outside air (air AR).

[0121] With the help of this feature, when the temperature difference between the air AR on the outside air side 70out and the air AR on the inside 70in of the clothing is in a relatively small state of, for example, several degrees Celsius (the third usage environment), if the air inlet port 31 introduces the air AR on the outside air side 70out, the resistance associated with the air AR flowing toward the air inlet port 31 can be suppressed to a smaller level compared to the case where the air AR is introduced from the inside 70in of the clothing forming a roughly closed space.

[0122] Therefore, in the clothing cooling device 1, the air AR introduced into the air inlet 31 by the air blower 20 can flow smoothly toward the Peltier element 11 (cooling module 10), and the cold air CF can also be blown from the cold air outlet with a smooth airflow.

[0123] The clothing cooling device 1 of this embodiment is characterized by including a control unit 15 , and the polarity of the direct current supplied to the Peltier element 11 is reversed by the control unit 15 , thereby switching the action between the first use example and the second use example.

[0124] With this feature, when the clothing cooling device 1 is used, in various usage environments such as the first usage environment to the third usage environment described above, the clothing cooling device 1 can flexibly cope with the first usage example and the second usage example according to the surrounding environment.

[0125] Furthermore, after the polarity of the DC current in the Peltier element 11 is reversed by operating the control unit 15, the usage mode of the clothing cooling device 1 can be easily switched between the first usage example and the second usage example by simply reversing the direction of the clothing cooling device 1 housed in the pocket 71 of the clothing 70 from the inside 70in of the clothing to the outside air side 70out or from the outside air side 70out to the inside 70in of the clothing.

[0126] Furthermore, the clothing cooling device 1 of the present embodiment is characterized in that the housing 30 is inserted into a pocket 71 formed on the clothing 70 , and at least one of the clothing inner side 70in and the outside air side 70out of the pocket 71 is formed with a mesh cloth 74 .

[0127] With this feature, if the mesh 74 is formed on the clothing inner side 70 in of the pocket 71 , the air AR (inside air) in the clothing 70 can be introduced into the air inlet 31 of the clothing cooling device 1 accommodated in the pocket 71 through the mesh 74 .

[0128] Furthermore, if the mesh 74 is formed on the outside air side 70 out of the pocket 71 , the air AR on the outside air side 70 out can be introduced into the air inlet 31 of the clothing cooling device 1 accommodated in the pocket 71 through the mesh 74 .

[0129] Furthermore, if the mesh 74 is formed on both the clothing inner side 70in and the outside air side 70out of the pocket 71, the air AR introduced into the air inlet 31 can be both the inside air and the outside air. Thus, the clothing cooling device 1 can cope with the case where the first use example and the second use example are selectively used.

[0130] As mentioned above, although this invention was demonstrated combining embodiment, this invention can be used with modification as needed within the range which does not deviate from the summary, and is not limited to the said embodiment.

[0131] For example, in an embodiment, it is like Fig.14 As shown in FIG. 1 , pockets 71 are arranged at the neck, armpits and thighs of the garment 70 and the garment cooling device 1 is accommodated in each pocket 71. Fig.14 The diagram is just for the convenience of observation.

[0132] Therefore, the position of the clothing cooling device 1 arranged on the clothing is not Fig.14 The exact position shown in the figure is not limited to the Fig.14 Position shown.

[0133] That is, the cooling device 1 for clothing installed by inserting into a pocket is arranged in a position taking into account the easy mobility of the person actually wearing the clothing 70, with a focus on the neck, the armpits and the flanks where sweating occurs, in particular, and on the premise that it can cool the blood in the arteries passing near these parts and can cool the parts of the body that are prone to sweating.

[0134] In addition, in the embodiment, the outer shape of the clothing cooling device 1 is set to Figure 1 to Figure 5 The shape shown in the figure, however, the outer shape of the cooling device 1 for clothing can be changed as appropriate and is not limited to the embodiment.
