However, in recent years, daytime temperatures on extremely hot days have been rising year by year, increasing the risk of heatstroke for workers working outdoors in extremely hot weather. There is a need for cooling clothing that improves the cooling efficiency of Peltier element units.

The technique of Patent Document 1 has the following problems.
The first problem is that the Peltier element unit disclosed in Patent Document 1 has only a cooling plate and no cooling fins, so that sufficient heat exchange cannot be performed. The second problem is that the Peltier element unit disclosed in Patent Document 1 takes in cooling air from outside the clothing, so if the outside of the clothing is exposed to direct sunlight, the outside temperature will drop. The temperature is close to 50°C, which poses a problem of poor heat exchange efficiency.

The present disclosure has been made in order to solve the above-mentioned problems, and improves the cooling efficiency of the Peltier device unit while suppressing the power consumption of the Peltier device unit. The purpose is to provide cooling clothing that avoids the risk of

In one aspect of the present disclosure made to solve the above problems, there is provided a Peltier device unit having a Peltier device, in which a cooling surface and a heat exchange surface are formed on the front and back sides, and a Peltier device unit formed on clothing, when the Peltier device unit is worn. In the cooling garment, the cooling surface includes an insertion hole for attaching the cooling surface to the wearer's body in close contact with the wearer's body, the heat exchange surface having a plurality of cooling fins, and the Peltier element unit cooling the cooling fins. The cooling surface and the air cylinder have a cylindrical air cylinder with air holes formed around the circumference, and a discharge part for discharging the air heat exchanged with the heat exchange surface, and the cooling surface and the air cylinder A flange attached to the body side and protruding outward at an end opposite to the cooling surface in the axial direction of the air cylinder, and an annular flange attached from the end opposite to the cooling surface. The Peltier element unit is removably attached to the clothing by the flange and the annular flange, and the flange has a diameter of 15 mm on the discharge part side with respect to a plane parallel to the cooling surface. The annular flange has an inclined surface of 15 degrees or more and 30 degrees or less on the discharge part side in the same direction as the flange; By tilting the annular flange at an angle of 15 degrees or more and 30 degrees or less toward the discharge portion, the air flowing in from the air hole flows toward the root of the cooling fin, thereby increasing the number of cooling fins. It was designed to allow air to reach the

According to this aspect, in the cooling garment that cools the wearer's body by bringing the cooling surface of the Peltier element unit into close contact with the wearer's body, the plurality of cooling fins of the heat exchange surface of the Peltier element unit are connected to the air cylinder. It is cooled by the air taken in through the air holes. The Peltier element unit inserted into the insertion hole by the flange projecting outward at the end opposite to the cooling surface and the annular flange provided in the annular body is detachably attached to clothing.

In other words, the area for heat exchange can be significantly increased by the cooling fins, and by having an inclined surface of 15 degrees or more and 30 degrees or less on the flange, the air can flow into the air holes for cooling. Some of the air that comes hits the flange, creating a downward flow. As a result, by changing the flow of air flowing in below the flange to the root side of the cooling fin, the entire cooling air reaches the center of the cooling fin when viewed from above, resulting in cooling. Efficiency can be increased by about 10% compared to the case where the flanges are parallel. By increasing the cooling efficiency by about 10%, for example, if the air is discharged from the exhaust section by rotating a fan using a motor, the power consumption of the motor can be reduced by about 10%, and the effective cooling of the cooling clothing can be reduced. For example, the time can be increased from 120 minutes to 132 minutes. Therefore, it is possible to reduce the power consumption of the Peltier element unit, increase the cooling efficiency of the Peltier element unit, and avoid the risk of heatstroke for workers working outdoors in extremely hot weather.

In the above aspect, it is preferable that the angle of inclination of the inclined surface of the annular flange is larger than the angle of inclination of the inclined surface of the flange.

According to this aspect, since the angle of inclination of the inclined surface of the annular flange is larger than the angle of inclination of the inclined surface of the flange, the area in which the inclined surface of the flange contacts the clothing is reduced. Thereby, the Peltier element unit can be made difficult to come off from clothing, and the air taken in from the air holes of the air cylinder can be guided to the plurality of cooling fins.

In the above aspect, the cooling clothing takes in air existing on the body side of the clothing through the air holes, cools the cooling fins with the air, and exchanges heat with the heat exchange surface from the discharge portion. It is preferable to have a function of discharging the air.

According to this aspect, the function of the cooling clothing allows the air existing on the body side of the clothing to be taken in through the air holes, the cooling fins are cooled by the air, and the air that has been heat exchanged on the heat exchange surface is discharged from the discharge section. Let it drain. Thereby, the air guided to the roots of the plurality of cooling fins by the flange does not remain in the Peltier element unit and is efficiently discharged from the discharge section, so that the cooling efficiency of the Peltier element unit can be improved.

In the above aspect, the clothing is provided with a control unit in which the insertion holes are arranged at a plurality of locations and can electrically control the Peltier device unit, and when there is a plurality of Peltier device units, the control unit It is preferable that the parts can be electrically connected to the plurality of Peltier element units by each of the main lines that are independent of each other, or by branch lines that are divided and extended from the main line that is assembled into a single strip.

The heat exchange surface 49 has a plurality of (for example, 117) cooling fins 49a configured in a protrusion shape. Since the cooling fins 49a are configured in a protruding shape, the surface area of the cooling fins 49a is expanded, and the portion that comes into contact with air is expanded, making it possible to efficiently radiate heat from the Peltier element.

As shown in FIG. 11, a convex portion 42 is provided at the end opposite to the heat radiation surface 41 (cooling surface 41A, heating surface 41B) in the axis AX direction of the air cylindrical portion 48. The convex portion 42 is formed in a cylindrical shape, and is provided with an inner flange 44 projecting in the shape of an annular plate from the outer peripheral end.

As shown in FIG. 11, the air blower 70 of the first embodiment includes a heat exhaust fan 71 that blows air, and a heat exhaust fan drive unit 72 that is controlled by a motor (not shown) that rotates the heat exhaust fan 71. Equipped with Thereby, the air heat exchanged by the heat exchange surface 49 is discharged from the discharge section 43a by the wind generated by the rotation of the heat exhaust fan 71.

The ring fastener 45 is formed to be freely fastened to or released from the convex portion 42 which is the end opposite to the heat radiation surface 41 (cooling surface 41A, heating surface 41B). The ring fastener 45 includes an annular outer flange 46 projecting in the shape of an annular plate. In the air-conditioning temperature-conditioning vest 1, the three Peltier device units 40 (first Peltier device unit 40A, second Peltier device unit, and third Peltier device unit 40C) are attached to the device mounting portions 20 at three locations on the vest body 2. be done.

In the Peltier device unit 40, the Peltier device is electrically connected to the portable battery 54 via the temperature control operation unit 60 by temperature control wiring 65, as shown in FIGS. 1 and 4.

For example, when three Peltier device units 40 are attached to the air conditioning temperature control vest 1, the temperature control wiring 65 is divided into three temperature control wires extending from the temperature control main line 66 gathered together in a single strip at the temperature control branch part 67. The configuration includes a branch line 66A, a temperature control branch line 66B, and a temperature control branch line 66C. That is, the number of temperature control branch lines 66A, temperature control branch lines 66B, temperature control branch lines 66C, etc. matches the number of Peltier element units 40.

A temperature control main line 66 of the temperature control wiring 65 is connected to the portable battery 54. For example, the temperature control branch line 66A is connected to the first Peltier element unit 40A. For example, the temperature control branch line 66B is connected to the second Peltier element unit 40B. For example, the temperature control branch line 66C is connected to the third Peltier element unit 40C. However, it is not limited to this. If the temperature control branch lines 66A, 66B, and 66C have a one-to-one connection relationship with the three Peltier device units 40 (first to third Peltier device units 40A, 40B, and 40C), the temperature control branch lines 66A, 66B, and 66C can be connected under the judgment of the wearer HM. In particular, the wiring route can be simplified and connections can be made arbitrarily.

The inner lining 12 is not sewn so as to be in contact with the back clothing material 3B.

The first Peltier element unit 40A is attached to the element attachment part 20 of the nape of the neck 18. In this case, as shown in FIG. 14, the heat dissipation surface 41 (the cooling surface 41A or the heating surface 41B) is brought into contact with the wearer HM's own body side (the nape of the neck) while facing the wearer HM of the air-conditioning temperature-conditioning vest 1. . As a result, the heat dissipation surface 41 (cooling surface 41A or heating surface 41B) can be brought into contact with the body surface of the wearer HM, either directly or indirectly through underwear or the like, thereby cooling the wearer's neck. .

As shown in FIG. 14, the first Peltier element unit 40A is attached to the element mounting part 20 provided in the fourth air guide path 14D formed by the fourth pair of air passage regulating parts 15D.

As shown in FIG. 14, the lining 12 forming the fourth pair of air passage regulating portions 15D is sewn so as to be in contact with the back side clothing 3B.

<About the inclination angle of the flange>
The inclination angles of the inner flange 44 and the outer flange 46 will be explained using FIGS. 15 and 16. FIG. 15 is a cross-sectional view of the Peltier element unit attached to the element attachment part. FIG. 16 is an enlarged cross-sectional view of the inner flange and outer flange shown in FIG. 15. 15 and 16 are drawings in which the Peltier device unit 40 (first Peltier device unit 40A, second Peltier device unit 40B, third Peltier device unit 40C) is attached to the device mounting portion 20. .

As shown in FIGS. 15 and 16, the surface 44a of the inner flange 44 and the surface 46a of the outer flange 46 of the Peltier element unit 40 are in contact with the element mounting portion 20, that is, are in surface contact. The surface contact between the surface 44a of the inner flange 44 and the surface 46a of the outer flange 46 can prevent the Peltier element unit 40 from coming off from the element mounting portion 20.

As shown in FIGS. 15 and 16, the back surface 44b of the inner flange 44 and the back surface 46b of the outer flange 46 are not in contact with the element mounting portion 20.

As shown in FIGS. 15 and 16, the front surface 44a and the back surface 44b of the inner flange 44 are connected to a discharge hole formed in the lid part 43 with respect to a surface parallel to the heat radiation surface 41 (cooling surface 41A or heating surface 41B). It is inclined toward the portion 43a side. Note that the inclination angle θ of the front surface 44a and the back surface 44b of the inner flange 44 in the first embodiment is 20 degrees.

As shown in FIGS. 15 and 16, like the inner flange 44, the front surface 46a and the back surface 46b of the outer flange 46 are arranged in a direction parallel to the heat radiation surface 41 (the cooling surface 41A or the heating surface 41B). 43 is inclined toward the discharge portion 43a side. Note that the inclination angle θ of the front surface 46a and the back surface 46b of the outer flange 46 in the first embodiment is 20 degrees.

<About the function that changes the air flow of the flange>
The inclination angle θ of the front surface 44a and the back surface 44b of the inner flange 44 of the Peltier element unit 40 of the first embodiment is 20 degrees with respect to the heat radiation surface 41 (cooling surface 41A or heating surface 41B). Thereby, the inner flange 44 of the Peltier element unit 40 has a function of changing the flow of air flowing into the air hole 47 of the Peltier element unit 40 downward. The function of changing the flow of air flowing into the air hole 47 of the Peltier element unit 40 downward, which the inner flange 44 of the Peltier element unit 40 of the first embodiment has, will be described with reference to FIGS. 17 to 18.

FIG. 17A is an explanatory diagram showing the flow of air flowing into the air holes of the comparative example. FIG. 17B is an explanatory diagram showing the flow of air flowing into the air holes of the first embodiment. FIG. 18A is an explanatory diagram showing the velocity distribution of air flowing into the air holes of the comparative example. FIG. 18B is an explanatory diagram showing the velocity distribution of air flowing into the air holes of the first embodiment.

The inclination angle θ of the front surface 44a and back surface 44b of the inner flange 44 of the Peltier element unit 40 in the comparative example is 0° with respect to the heat radiation surface 41 (cooling surface 41A or heating surface 41B). That is, as shown in FIG. 17A, the inner flange 44 of the Peltier element unit 40 is parallel to the heat radiation surface 41 (cooling surface 41A or heating surface 41B). As a result, the inner flange 44 of the Peltier element unit 40 in the comparative example does not have the function of changing the flow of air flowing into the air hole 47 of the Peltier element unit 40 downward.

As shown in FIG. 17A, when the inclination angle θ of the inner flange 44 of the comparative example is 0°, the air AR (air AR1, air AR2, air AR3, air AR4) flow toward the air hole 47. Air AR (air AR1, air AR2, air AR3, air AR4) flows into the air hole 47 without colliding with the inner flange 44, and flows into the inside of the Peltier element unit 40. The air AR (air AR1, air AR2, air AR3, air AR4) flowing into the inside of the Peltier element unit 40 comes into contact with the plurality of cooling fins 49a and the heat exchange surface 49.

As shown in FIG. 17B, when the inclination angle θ of the inner flange 44 is 20°, air AR (air AR4, air AR5, air AR6, air AR7) flow toward the air hole 47. Air AR4 then impinges on inner flange 44, as shown in FIG. 17B. This increases the velocity of the air AR4 and lowers the pressure on the air AR4. As shown in FIG. 17B, the air AR4 flows toward the roots of the cooling fins 49a of the heat exchange surface 49 along the inner flange 44 having an inclination angle θ of 20°.

As shown in FIG. 17B, the air AR5 flowing toward the air hole 47 is compressed downward by the air AR4 flowing toward the air hole 47 along the inner flange 44 having an inclination angle θ of 20°. Thereby, the flow of the air AR5 is changed to the root side of the cooling fin 49a.

As shown in FIG. 17B, the air AR4 that has passed through the air hole 47 flows into the Peltier element unit 40. As shown in FIG. 17B, the air AR6 that has flowed into the Peltier element unit 40 through the air hole 47 is compressed downward by the air AR4 that has flowed into the Peltier element unit 40. Thereby, the flow of the air AR6 is changed to the root side of the cooling fin 49a.

As shown in FIG. 17B, the inner flange 44 of the first embodiment directs the flow of air AR4 that has collided with the inner flange 44 downward, thereby directing the flow of air AR5 and air AR6 toward the air holes 47 to the cooling fins 49a. It has the function of changing the shape so that it flows towards the root of the .

Next, using FIG. 18A, a change in the air velocity distribution when the inner flange 44 of the comparative example is parallel to the heat radiation surface 41 (the cooling surface 41A or the heating surface 41B) will be described.

A first comparison speed distribution HP1 shown in FIG. 18A is a speed distribution of a portion of the air sent by the blower unit 30 as the fan 32 rotates. As shown in FIG. 18A, the apex of the first comparative velocity distribution HP1 near the inner flange 44 of the comparative example faces the cooling fins 49a of the heat exchange surface 49. The first comparative velocity distribution HP1 moves toward the cooling fins 49a that the heat exchange surface 49 has.

The speed distribution of a portion of the air when the air sent by the blower unit 30 as the fan 32 rotates moves below the inner flange 44 of the Peltier element unit 40 is the second comparison speed distribution shown in FIG. 18A. HP is 2. As shown in FIG. 18A, the apex of the second comparative speed distribution HP2 near the inner flange 44 of the Peltier element unit 40 faces the cooling fins 49a of the heat exchange surface 49, similar to the first comparative speed distribution HP1. . The second comparative velocity distribution HP2 moves toward the cooling fins 49a that the heat exchange surface 49 has.

The velocity distribution of a portion of the air when the air sent by the ventilation unit 30 as the fan 32 rotates moves into the Peltier element unit 40 is a third comparative velocity distribution HP3 shown in FIG. 18A. As shown in FIG. 18A, the apex of the third comparative velocity distribution HP3 that has moved inside the Peltier element unit 40 faces the cooling fins 49a that the heat exchange surface 49 has. When the inner flange 44 of the comparative example is parallel to the heat dissipation surface 41 (the cooling surface 41A or the heating surface 41B), the flow of air toward the air holes 47 is not changed by the inner flange 44, and the air flow is directed toward the cooling fins 49a. It will be moved.

Next, using FIG. 18B, changes in air velocity distribution when the inner flange 44 of the first embodiment is inclined at an inclination angle of 20° with respect to the heat radiation surface 41 (cooling surface 41A or heating surface 41B) I will explain about it.

A first gradient velocity distribution ZP1 shown in FIG. 18B is a velocity distribution of a portion of the air that is blown as the fan 32 by the blower unit 30 rotates near the inner flange 44 of the first embodiment. As shown in FIG. 18B, the apex of the first gradient velocity distribution ZP1 near the inner flange 44 of the first embodiment faces the cooling fins 49a that the heat exchange surface 49 has. The first gradient velocity distribution ZP1 moves toward the cooling fins 49a of the heat exchange surface 49.

Next, when the air sent by the fan unit 30 as the fan 32 rotates is moved downward by the inner flange 44 of the first embodiment, the velocity distribution of a portion of the air is as shown in FIG. 18B. This is a slope velocity distribution ZP2. A part of the air sent by the fan 32 by the blower unit 30 flows along the inner flange 44 having an inclination angle θ of 20° toward the root of the cooling fin 49a of the heat exchange surface 49. (See Figure 17B). As a result, the apex of the second gradient velocity distribution ZP2 moves to the root side of the cooling fin 49a and faces the root of the cooling fin 49a that the heat exchange surface 49 has. The second gradient velocity distribution ZP2 moves toward the roots of the cooling fins 49a of the heat exchange surface 49.

Next, the velocity distribution of the air when the air sent by the rotation of the fan 32 by the ventilation unit 30 moves into the Peltier element unit 40 is a third gradient velocity distribution ZP3 shown in FIG. 18B. Air accompanying the rotation of the fan 32 flows toward the base of the cooling fins 49a of the heat exchange surface 49 along the inner flange 44 having an inclination angle θ of 20° (see FIG. 17B). As a result, the apex of the third gradient velocity distribution ZP3 faces the root of the cooling fin 49a of the heat exchange surface 49, similarly to the second gradient velocity distribution ZP2. As a result, the air flowing toward the air hole 47 of the first embodiment collides with the inner flange 44 of the first embodiment, speed increases, and pressure decreases, as shown in FIG. 18B. The flow changes toward the base of the cooling fin 49a.

A part of the air sent by the fan 32 by the blower unit 30 flows along the inner flange 44 having an inclination angle θ of 20° toward the root of the cooling fin 49a of the heat exchange surface 49. (See Figures 17B and 18B). Thereby, the inner flange 44 of the first embodiment can change the flow of air flowing in below the inner flange 44 to the root side of the cooling fin 49a. Therefore, when the cooling fins 49a are viewed in plan, the entire cooled air (e.g., 35° C.) contained in the air-conditioning temperature-control vest 1 may come into contact with the air flowing in from the air holes 47 of the comparative example. It will reach the cooling fins 49a located directly below the air blower 70, which was not present. Therefore, the cooling efficiency by the Peltier element unit 40 of the first embodiment can be increased by about 10% compared to the case where the inner flanges 44 are parallel (see FIGS. 17A and 18A). By increasing the cooling efficiency of the Peltier element unit 40 by about 10%, the power consumption of the motor that rotates the heat exhaust fan 71 can be reduced by about 10%, and the effective cooling time of the air conditioning temperature control best 1 can be reduced by, for example, 120%. minutes to 132 minutes.

<About double raschel fabric>
Next, the double raschel fabric included in the lining 12 of the air-conditioned and temperature-controlled vest 1 of the first embodiment will be explained using FIGS. 19 to 20. FIG. 19 is a view of the lining shown in FIG. 7 in the direction of arrow F. FIG. 20 is an enlarged cross-sectional view of the double raschel fabric.

The double raschel fabric included in the lining 12 has a surface layer 81, a back layer 82, and a large number of connecting threads 83.

It also has a structure in which regular hexagonal columns of holes with extremely high porosity are lined up without gaps.

Further, the back layer 82 of the double raschel fabric is made of thread-like fibers similar to the surface layer 81, and has a structure in which regular hexagonal columns of holes with extremely high porosity are arranged without gaps. Further, as shown in FIG. 20, the front layer 81 and the back layer 82 of the double raschel fabric are connected by a connecting thread 83, and have a structure having pores with an extremely high porosity.

For example, if the thickness of the lining 12 is small (for example, about 1 cm), the air guide path 14 will be able to move the air blown in by the blower unit 30 as the fan 32 rotates to the collar part 9 and the armhole part 10 ( It becomes difficult to guide it toward the first armhole portion 10A and the second armhole portion 10B). On the other hand, if the thickness of the lining 12 is too large (for example, 10 cm), it will be difficult for the air taken in from the ventilation unit 30 to pass through the lining 12. Therefore, the thickness of the double raschel fabric included in the lining 12 of the first embodiment is such that the air taken in from the blower unit 30 passes through the lining 12 and the neck area 9 and armholes 10 (first armholes) 10A and the second armhole 10B), the length is about 2 cm.

<About the air flow inside the air conditioning temperature control vest 1>
Next, the flow of air within the air-conditioning and temperature-controlling vest 1 will be explained using FIGS. 21 to 23.

As shown in FIG. 21, the air AR branched from the first air guide path 14A to the second air guide path 14B is guided toward the first armhole 10A by the second air guide path 14B, and It is discharged to the outside of the air-conditioning and temperature-controlling vest 1 from the armhole 10A.

As shown in FIG. 21, the air AR branched from the first air guide path 14A to the third air guide path 14C is guided toward the second armhole 10B by the third air guide path 14C, and 2 is released to the outside of the air-conditioning and temperature-controlling vest 1 through the armholes 10B.

As shown in FIG. 21, the air AR branched from the first air guide path 14A to the fourth air guide path 14D is guided toward the collar portion 9 by the fourth air guide path 14D, and from the collar portion 9 It is released to the outside of the air conditioning and temperature conditioning vest 1.

As shown in FIG. 22, when the wearer HM is wearing the air conditioning and temperature conditioning vest 1, air is taken in from the outside of the air conditioning and temperature conditioning vest 1 and is sent in as the fan 32 by the ventilation unit 30 rotates. The air AR is flown out. Next, the air AR crosses into any one of the first air guide path 14A, the second air guide path 14B, the third air guide path 14C, or the fourth air guide path 14D. Branch out.

The air AR flowing through any one of the second air guide path 14B, the third air guide path 14C, or the fourth air guide path 14D is transferred to the collar portion 9, the first armhole portion It is discharged to the outside of the air-conditioning and temperature-controlling vest 1 from either the second armhole 10A or the second armhole 10B. As a result, the body is cooled by the air guided by the air guide path 14, and air is efficiently released from the collar section 9 and armhole sections 10 (first armhole section 10A and second armhole section 10B). can be done.

An internal space is formed between the back side clothing 3B and the lining 12 of the air-conditioned and temperature-controlled vest 1 of the first embodiment. The ventilation unit 30 and the Peltier device unit 40 (first Peltier device unit 40A, second Peltier device unit, and third Peltier device unit 40C) are provided in the internal space.

The air-conditioning and temperature-controlling vest 1 allows the cooled air present in the air-conditioning and temperature-controlling vest 1 to flow in through the air holes 47, cools the cooling fins 49a with the air, and discharges the heat-exchanged air from the discharge section 43a. It has a heat exchange function to discharge heat. The heat exchange function that the air conditioning temperature control vest 1 has will be explained using FIG. 23.

As shown in FIG. 23, the air AR sent in with the rotation of the fan 32 by the ventilation unit 30 passes through the lining 12 of the double raschel fabric and flows toward the collar part 9, and also flows through the back side clothing 3B and the lining 12. It also flows into the internal space formed between them. Thereafter, the air AR flows toward the collar portion 9, the first armhole portion 10A, and the second armhole portion 10B.

For example, the air AR flowing toward the collar part 9 through the fourth air guide path 14D, and the air AR flowing into the fourth air guide path 14D from the internal space between the back clothing material 3B and the lining 12, are As shown in 23, the air flows into the air hole 47 of the first Peltier element unit 40A. Air flowing in through the air holes 47 comes into contact with the heat exchange surface 49 and the plurality of cooling fins 49a, so that heat exchange by the heat exchange surface 49 is performed. The air heated by contacting the heat exchange surface 49 is discharged from the discharge portion 43a into the internal space between the back side clothing 3B and the lining 12 by the wind generated as the heat exhaust fan 71 rotates.

Thereafter, the air discharged into the internal space between the back clothing material 3B and the lining 12 is transferred from the collar part 9 to the outside of the air-conditioning temperature-conditioning vest 1 by the air AR flowing in the internal space toward the collar part 9. It will be released.

Similarly to the first Peltier element unit 40A, the second Peltier element unit and the third Peltier element unit 40C are also cooled by the air flowing in from the air hole 47 coming into contact with the heat exchange surface 49 and the plurality of cooling fins 49a. . Thereafter, the air heated by contacting the heat exchange surface 49 is discharged from the discharge part 43a into the internal space between the back side clothing 3B and the lining 12 by the wind generated as the heat exhaust fan 71 rotates. . The air discharged into the internal space between the back side fabric 3B and the lining 12 is caused by the air AR flowing through the internal space toward the armhole 10 (first armhole 10A, second armhole 10B). , is released from the armhole 10 (first armhole 10A, second armhole 10B).

The air blowing display section 53 is a display section on the upper surface of the air blowing operation unit 50, and is configured to be able to emit white light.

<About the temperature control unit>
FIG. 25 is a block diagram showing the configuration of a temperature control operation unit included in the air conditioning temperature control vest according to the embodiment. As shown in FIG. 25, the temperature adjustment operation unit 60 includes a temperature adjustment control section 61, a temperature adjustment operation section 62, a temperature adjustment display section 63, and the like. Inside the temperature adjustment operation unit 60, a temperature adjustment operation section 62 and a temperature adjustment display section 63 are electrically connected to the temperature adjustment control section 61.

The temperature control operation section 62 allows the first to third Peltier device units 40A, 40B, and 40C to switch on/off the energization of the Peltier devices by pressing down the push part on the top surface of the temperature control operation unit 60. It is configured in a manner that allows operations for control. Furthermore, the temperature control operation unit 62 controls the switching operation of turning on/off the energization of a motor (not shown) that rotates the heat exhaust fan 71 by pressing down a push part on the top surface of the temperature control operation unit 60. It is configured in such a manner that it can be operated. The temperature control display section 63 is a display section on the top surface of the temperature control operation unit 60, and is configured in such a manner that it can selectively emit light from a plurality of colors.

When the temperature control unit 61 has a control for reversing the direction of the direct current supplied from the portable battery 54 to the Peltier element, the temperature control operation unit 62 controls the pressing part on the top surface of the temperature control operation unit 60 to turn on/off the energization. Light press based on a predetermined operating mode different from the off switching operation. Thereby, it is possible to switch the polarity of the current flowing through the first to third Peltier element units 40A, 40B, and 40C.

In the Peltier element unit 40, when the direction of the supplied DC current is reversed in the Peltier element, the function of one side and the function of the other side are mutually reversed. Therefore, when the temperature control section 61 is configured to be able to reverse the polarity of the current supplied to the Peltier element, the heat dissipation surface 41 is cooled by heat absorption by the temperature control section 61, and the heat generation surface 41A is cooled by heat absorption. The heated surface 41B can be selectively varied. Thereby, in the heat dissipation surface 41, the cooling surface 41A and the heating surface 41B are replaced with each other. Note that if the temperature adjustment control unit 61 does not have a function of switching the direction of current to the Peltier element, the heat radiation surface 41 is either the cooling surface 41A or the heating surface 41B.

<Second embodiment>
Hereinafter, the features of the air conditioning temperature control vest 1 of the second embodiment will be explained in detail. Unless otherwise stated, the air conditioning temperature control vest 1 of the first embodiment is also applied to the second embodiment. Of course, the configurations according to the second embodiment may be combined as appropriate. The technical features in the first embodiment described above and the second embodiment described below can be deleted as appropriate unless they are described as essential in this specification.

The inclination angle θ of the front surface 44a and the back surface 44b of the inner flange 44 of the Peltier element unit 40 according to the first embodiment was 20 degrees. The inclination angle θ of the front surface 46a and the back surface 46b of the outer flange 46 of the Peltier element unit 40 according to the first embodiment was 20 degrees. However, it is not limited to this. The inclination angle θ of the front surface 46a and the back surface 46b of the outer flange 46 of the Peltier element unit 40 according to the second embodiment is larger than the inclination angle θ of the front surface 44a and the back surface 44b of the inner flange 44 of the Peltier element unit 40. shall be.

The inner flange 44 and outer flange 46 of the Peltier element unit 40 according to the second embodiment will be explained using FIG. 26. FIG. 26 is an enlarged sectional view of the inner flange and outer flange according to the second embodiment. Note that FIG. 26 is a diagram showing a state in which the Peltier device units 40 (first Peltier device unit 40A, second Peltier device unit 40B, and third Peltier device unit 40C) are attached to the device mounting portion 20.

As shown in FIG. 26, the back surface 44b of the inner flange 44 and the back surface 46b of the outer flange 46 are not in contact with the element mounting portion 20.

As shown in FIG. 26, the front surface 44a and back surface 44b of the inner flange 44 are on the side of the discharge section 43a formed in the lid section 43 with respect to a surface parallel to the heat radiation surface 41 (cooling surface 41A or heating surface 41B). is inclined to. Note that the inclination angle θ of the front surface 44a and the back surface 44b of the inner flange 44 in the second embodiment is 15 degrees.

As shown in FIG. 26, like the inner flange 44, the front surface 46a and back surface 46b of the outer flange 46 are formed on the lid part 43 with respect to a surface parallel to the heat radiation surface 41 (cooling surface 41A or heating surface 41B). It is inclined toward the discharge part 43a side. Note that the inclination angle θ of the front surface 46a and the back surface 46b of the outer flange 46 in the second embodiment is 20 degrees.

As shown in FIG. 26, the surface 46a of the outer flange 46 is in surface contact with the element mounting portion 20. On the other hand, as shown in FIG. 26, the inclination angle θ of the surface 46a of the outer flange 46 is 5° larger than the inclination angle θ of the surface 44a of the inner flange 44. When the Peltier element unit 40 is attached to the element attachment part 20, a part of the surface 44a of the inner flange 44 comes into contact with the element attachment part 20 (eg, line contact, point contact). Therefore, the contact area between the element mounting portion 20 and the surface 44a of the inner flange 44 of the second embodiment is smaller than that of the first embodiment, so the surface pressure on the contact surface is increased. Therefore, it is more possible to prevent the Peltier element unit 40 from coming off from the element attachment part 20 than when the surface 44a of the inner flange 44 and the surface 46a of the outer flange 46 are in surface contact with the element attachment part 20. can.

Next, the functions and effects of the air conditioning temperature control vest 1 according to the present embodiment will be explained.

The air-conditioning temperature-conditioning vest 1 according to the first embodiment and the second embodiment includes a Peltier element unit 40 that has a Peltier element and has a cooling surface 41A and a heat exchange surface 49 formed on the front and back sides, and a Peltier element unit 40 that is formed on clothing and The heat exchange surface 49 has a plurality of cooling fins 49a, and the Peltier element unit 40 has , has a cylindrical air cylinder part 48 in which air holes 47 for cooling the cooling fins 49a are formed on the circumference, and a discharge part 43a for discharging the air heat exchanged on the heat exchange surface 49. The surface 41A and the air cylindrical portion 48 are attached to the body side of the air-conditioning and temperature-conditioning vest 1, and are the end opposite to the cooling surface 41A in the direction of the axis AX of the air cylindrical portion 48, and the convex portion 42 forms a circle from the outer peripheral end. An inner flange 44 protruding in the shape of an annular plate, and a ring fastener 45 including an outer flange 46 in the shape of an annular plate attached from the side of the convex portion 42 which is the end opposite to the cooling surface 41A are provided. 44 and an outer flange 46, the Peltier element unit 40 is removably attached to the air-conditioning temperature-controlling vest 1, and the inner flange 44 has a surface 44a that is oriented at 20 degrees toward the discharge part 43a side with respect to a plane parallel to the cooling surface 41A. and a back surface 44b, and the outer flange 46 has a front surface 46a and a back surface 46b at 20 degrees toward the discharge part 43a in the same direction as the inner flange 44.

With such features, the area for heat exchange of the heat exchange surface 49 can be significantly increased by the plurality of cooling fins 49a. Furthermore, since the front surface 44a and the back surface 44b of the inner flange 44 are at an angle of 20 degrees, a portion of the air flowing into the air holes 47 for cooling collides with the inner flange 44, resulting in a downward flow. As a result, the flow of air flowing in below the inner flange 44 is changed to the root of the cooling fin 49a, so that the entire cooling air at about 35° C. inside the air conditioning temperature conditioning vest 1 flows through the cooling fin 49a in a flat manner. When viewed, it reaches the center of the heat exchange surface 49. Therefore, the cooling efficiency can be increased by about 10% compared to the comparative example in which the inner flanges 44 are parallel (see FIGS. 17A and 18A). By increasing the cooling efficiency by about 10%, the power consumption of the motor that rotates the heat exhaust fan 71 can be reduced by about 10%, and the effective cooling time of the air conditioning temperature control best 1 can be extended from, for example, 120 minutes to 132 minutes. be able to. Therefore, while suppressing the power consumption by the Peltier element unit 40, it is possible to increase the cooling efficiency of the cooling surface 41A and avoid the risk of heat stroke for workers working outdoors in extremely hot weather.

Furthermore, in the air-conditioning and temperature-controlling vest 1 according to the first embodiment, the front surface 44a and back surface 44b of the inner flange 44 and the front surface 46a and back surface 46b of the outer flange 46 have an inclination angle θ of 20 degrees.

According to this aspect, since the surface 44a of the inner flange 44 and the surface 46a of the outer flange 46 have an inclination angle θ of 20°, the surfaces of both flanges are brought into surface contact with the element mounting portion 20. This prevents the Peltier element unit 40 from coming off the element mounting part 20, and allows the air sent in with the rotation of the fan 32 to flow in from the air hole 47 of the air cylinder part 48, thereby preventing the heat exchange surface from coming off. 49 can be brought into contact with cold air.

In addition, in the air-conditioning temperature-control vest 1 according to the second embodiment, the inclination angle θ (20°) of the surface 46a of the outer flange 46 is greater than the inclination angle θ (15°) of the surface 44a of the inner flange 44. It's also big.

According to this aspect, the inclination angle θ (20°) of the surface 46 a of the outer flange 46 is 5° larger than the inclination angle θ (15°) of the surface 44 a of the inner flange 44 . A portion of the surface 44a contacts the element mounting portion 20. As a result, it is easier for the Peltier element unit 40 to come off when a part of the surface 44a of the inner flange 44 contacts the element mounting part 20 than when the entire surface 44a of the inner flange 44 contacts the element mounting part 20. It can be made difficult. Therefore, while preventing the Peltier element unit 40 from coming off from the element mounting part 20, the air sent in with the rotation of the fan 32 is allowed to flow in from the air hole 47 of the air cylinder part 48, and the heat exchange surface 49 can be brought into contact with cold air.

In addition, the air-conditioning and temperature-controlling vest 1 according to the first and second embodiments allows the air existing on the body side of the air-conditioning and temperature-controlling vest 1 to be taken in through the air holes 47, and the heat exchange surface 49 is heated by the air. It has a function of cooling the plurality of cooling fins 49a and discharging the air heat exchanged on the heat exchange surface 49 from the discharge section 43a.

According to this aspect, the function of the air-conditioning temperature-conditioning vest 1 causes the air existing on the body side of the air-conditioning temperature-conditioning vest 1 to flow in from the air hole 47, cools the cooling fins 49a with the air, and discharges the air from the discharge part 43a. It has a function of discharging the air that has been heat exchanged with the heat exchange surface 49. As a result, the air guided to the base of the cooling fins 49a by the inner flange 44 does not remain in the Peltier element unit 40 and is efficiently discharged from the discharge portion 43a, so that the cooling efficiency of the Peltier element unit 40 can be improved. can.

In addition, in the air-conditioning temperature-conditioning vest 1 according to the first embodiment and the second embodiment, the element insertion holes 22 are arranged near the nape of the neck 18, the first armhole 10A, and the second armhole 10B, and the Peltier It is equipped with a temperature control section 61 that can electrically control the element units, and each branch line (temperature control branch line 66A, temperature control branch line 66B, It can be electrically connected to the three Peltier element units 40 (first Peltier element unit 40A, second Peltier element unit 40B, and third Peltier element unit 40C) through the temperature control branch line 66C).

According to this aspect, the three Peltier element units 40 (the first - third Peltier element units 40A, 40B, 40C) are controlled. As a result, when the pressing part on the top surface of the temperature control operation unit 60 is pressed down, the nape of the neck 18, the vicinity of the first armhole 10A, and the vicinity of the second armhole 10B are cooled by the cooling surface 41A, efficiently. The body of the wearer wearing the air-conditioning and temperature-controlling vest 1 can be cooled.
