Description

The present invention relates to an air conditioning unit and clothing provided with the air conditioning unit, and more particularly to a technique for cooling or heating the body of a user wearing the air conditioning unit.

Conventionally, there is known a garment with a fan that takes in external air into the garment by a fan attached to the garment and cools the body of the wearer (user) (for example, Patent Document 1). However, since clothes with a fan only send outside air into the clothes, the cooling effect is low when the outside temperature is high, and it cannot be said that the clothes are comfortable.

Further, conventionally, clothes that can cool or heat the body by flowing cold water or hot water through a water channel provided inside the clothes are also known (for example, Patent Document 2). However, in the configuration in which cold water or hot water is allowed to flow inside the clothes, the weight of the clothes increases, and there is a drawback that the user's movement becomes sluggish.

By the way, since cooling or heating can be performed by using a Pelche element, it is conceivable to attach the Pelche element to the user's body to cool or heat the body. For example, a method of attaching a Pelche element to a user's clothes or the like can be mentioned.

However, since the Pelche element consumes a large amount of power, if a large number of Pelche elements are attached to the inner surface side of clothes, the power consumption is severe and it cannot be put into practical use. Therefore, when using a Pelche element, it is desirable to reduce the number of Pelche elements so that the user's body can be efficiently cooled or heated.

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

(First Embodiment)
First, the first embodiment of the present invention will be described. FIG. 1 is a perspective view showing an example of an air conditioning unit 1 according to the first embodiment of the present invention, and FIGS. 1A and 1B are views viewed from different directions. FIG. 2 is a diagram showing an example of clothes 100 to which the air conditioning unit 1 is attached. FIG. 3 is an exploded perspective view showing an example of the configuration of the air conditioning unit 1. The air conditioning unit 1 of the present embodiment shown in these drawings exchanges heat using the Pelche element 17 to cool or heat the body of the wearer (user) of the garment 100. For example, as shown in FIG. 2, the air conditioning unit 1 is attached to the fabric 101 of the back body of the garment 100 to cool or heat the back portion of the user's body. The air conditioning unit 1 is a device that cools or heats a portion from between the user's scapula to the waist.

As shown in FIG. 3, the air conditioning unit 1 mainly includes a fan cover 11, a fan 14, a heat sink 15, a Pelche element 17, a holding member 18, a metal plate 19, a heat exchange plate 20, and heat insulation. It is configured to include a pad 30 and a fixed pad 40. In the air conditioning unit 1, the holding member 18 holds the Pelche element 17.

The Pelche element 17 is a thin plate element having a substantially rectangular shape, and two different types of metals are arranged on the front surface side and the back surface side, and one of them is formed by passing an electric current through the joint portion of the two types of metals. It is a semiconductor device that utilizes the Perche effect that heat is transferred from one metal to the other metal. For example, when a direct current is passed from one metal to the other metal, one surface of the Pelche element 17 absorbs heat and heat is generated on the other surface. When the polarity of the direct current is reversed, the surface on which the endothermic action and the heat generation action occur is reversed. The air conditioning unit 1 cools or heats the user's body by utilizing the characteristics of the Pelche element 17.

On the surface of the Pelche element 17 corresponding to the outside of the clothes, a heat dissipation mechanism for releasing the waste heat heat exchanged by the air conditioning unit 1 to the outside is provided. Specifically, the heat sink 15 is arranged so as to be joined to the surface of the Pelche element 17 corresponding to the outside of the clothes. For example, the heat sink 15 is fixed around the heat sink 15 to the holding member 18. The heat sink 15 is provided with a large number of fins 16 on the peripheral portion thereof in order to increase the heat exchange efficiency. A fan 14 is arranged on the outer side of the clothes of the heat sink 15 so as to face the heat sink 15. The fan 14 is a fan for releasing the heat of the heat sink 15 to the outside. The fan cover 11 is a cover member attached to the peripheral portions of the heat sink 15 and the fan 14, and is attached so as to cover the fan 14 and the heat sink 15 on the outside of the clothes 100. The fan cover 11 is provided with an intake window 12 (12a, 12b) for introducing air into the cover and an exhaust window 13 for discharging the air inside the cover to the outside. For example, the fan cover 11 is formed as a bottomed cylindrical shape having a peripheral wall 11b that covers the heat sink 15 and the sides of the fan 14, and a bottom portion 11a that covers the back surface side (outside of clothes) of the fan 14. The intake window 12a is formed on the bottom portion 11a of the fan cover 11, and the intake window 12b is formed on the bottom side of the peripheral wall 11b. Further, the exhaust window 13 is formed at a lateral position of the heat sink 15 (more specifically, the fin 16) of the peripheral wall 11b of the fan cover 11.

On the other hand, the surface of the Pelche element 17 corresponding to the inside of the clothes is provided with a heat conduction mechanism for efficiently transmitting the cooling or heating effect of the Pelche element 17 to the user's body. Specifically, the metal plate 19 is arranged so as to be joined to the surface of the Pelche element 17 corresponding to the inside of the clothes. The metal plate 19 is fixed, for example, with its peripheral edge bonded to the inner surface of the clothes of the holding member 18. The metal plate 19 is attached in a state where one surface thereof is joined to one surface of the Pelche element 17, so that the temperature is lowered or raised by the endothermic or heat generating action of the Pelche element 17. The metal plate 19 is made of, for example, aluminum metal. Aluminum metal has a relatively high thermal conductivity and is lightweight, so that it is suitable for wearing clothes. However, the metal plate 19 is not limited to the one made of aluminum, and any metal may be used as long as it is a metal exhibiting a relatively high thermal conductivity. For example, the metal plate 19 may be formed by using copper, tin, or the like.

It is preferable to use a metal plate 19 whose area is larger than the area of the Pelche element 17. By joining the metal plate 19 larger than the area of the Pelche element 17 to one surface of the Pelche element 17, the Pelche element 17 can be bonded to substantially the center of one surface of the metal plate 19, and one of the Pelche elements 17 can be joined. The heat absorbing action or heat generating work generated on the surface can be efficiently transmitted to the metal plate 19.

However, it is not preferable that the area of the metal plate 19 is too large with respect to the area of the Pelche element 17. Since the metal plate 19 lowers or rises in temperature as a whole due to the heat absorption or heat generation action of the Pelche element 17, if the heat capacity of the metal plate 19 becomes too large, a load is applied to the Pelche element 17, and the current consumption in the Pelche element 17 increases. This is because it will increase. Therefore, it is preferable that the area of the metal plate 19 is kept to about 1.5 to 4 times the area of the Pelche element 17.

The heat exchange plate 20 is a metal plate arranged so as to be joined to the surface of the metal plate 19 corresponding to the inside of the garment. A plate placed inside the garment 100 to cool or heat the user's body. For example, the heat exchange plate 20 is formed to have a size larger than that of the metal plate 19. Therefore, the heat capacity of the heat exchange plate 20 is larger than that of the metal plate 19. Further, the heat exchange plate 20 is formed by using, for example, a copper plate, a tin plate, an aluminum plate, or the like.

For example, when a copper plate is used as the heat exchange plate 20, the heat conductivity is relatively high, so that heat exchange can be performed efficiently. In this case, the heat exchange plate 20 uses, for example, a copper plate having a thickness of about 0.3 to 0.8 mm as a base material, and as shown in FIG. 3, the plate surface (front surface and back surface) excluding the joint portion 21 to be joined to the metal plate 19. It is preferable to use a tin-plated 22 (including both of the above). By setting the plate thickness to about 0.3 to 0.8 mm, it is possible to obtain an appropriate hardness for clothing. Further, since copper is easily oxidized, oxidation can be prevented by plating the plate surface with tin 22. Further, by not providing the tin plating 22 at the joint portion 21 with the metal plate 19, the heat absorbed from the user's body can be efficiently conducted to the metal plate 19.

Further, for example, when a tin plate is used as the heat exchange plate 20, it is softer than copper or aluminum, so that there is an advantage that the adhesion to the user's body is increased. In this case, the heat exchange plate 20 uses, for example, a tin plate having a thickness of about 0.5 to 1.0 mm as a base material, and the plate surface (including both the front surface and the back surface) excluding the joint portion 21 to be joined to the metal plate 19. It is preferable to use one plated with silver or copper 22. By setting the plate thickness to about 0.5 to 1.0 mm, it is possible to obtain an appropriate hardness for clothing. Further, since tin has a lower thermal conductivity than copper, the low thermal conductivity can be significantly improved by plating the plate surface with silver or copper 22. Further, by not providing the silver or copper plating 22 at the joint portion 21 with the metal plate 19, the heat absorbed from the user's body can be efficiently conducted to the metal plate 19.

Further, for example, when an aluminum plate is used as the heat exchange plate 20, for example, an aluminum plate having a thickness of about 0.5 to 0.8 mm is used as a base material. The aluminum plate in this case is anodized in advance. Corrosion due to oxidation of aluminum can be prevented by alumite treatment. Further, it is preferable to use an aluminum plate obtained by plating 22 with silver on the plate surface (including both the front surface and the back surface) excluding the joint portion 21 to be joined to the metal plate 19. Since silver has the highest thermal conductivity among metals, it can efficiently cool or heat the user's body.

The heat exchange plate 20 has a substantially inverted T-shape so as to directly or indirectly contact the portion from between the user's scapula to the waist and efficiently cool or heat the portion. It is formed so that the width of the lower part is wider than the width of the upper part. The reason why the width of the upper part is narrow is that even if the scapula is moved by the user's movement, the heat exchange plate 20 does not interfere with the user's scapula and does not cause discomfort to the user. On the other hand, by making the width of the lower part of the heat exchange plate 20 wider than that of the upper part, it is possible to widely cool or heat the area from the back to the waist of the user. The heat exchange plate 20 is not limited to a substantially inverted T-shape, and may be, for example, trapezoidal or triangular.

Further, the heat exchange plate 20 is provided with a hole 23 through which the screw 29 is inserted at the center position of the joint portion 21 to be joined to the metal plate 19. The screw 29 is inserted into the hole 23 from the inside to the outside of the garment, screwed into the screw hole provided on the inner surface of the garment of the metal plate 19, and the heat exchange plate 20 and the metal plate 19 are brought into each other. Fix it in the joined state. However, the present invention is not limited to this, and the heat exchange plate 20 and the metal plate 19 may be adhered to each other by an adhesive or the like.

The heat insulating pad 30 is a member that holds the peripheral edge of the heat exchange plate 20 and attaches the air conditioning unit 1 to the clothes 100. The heat insulating pad 30 has substantially the same shape as the heat exchange plate 20 so as to hold the peripheral edge portion of the heat exchange plate 20. For example, the heat insulating pad 30 is formed in a substantially inverted T shape like the heat exchange plate 20. However, when the heat exchange plate 20 has a shape different from the substantially inverted T shape (for example, a trapezoid or a triangle), the heat insulating pad 30 has a shape suitable for the shape of the heat exchange plate 20.

The heat insulating pad 30 is formed of, for example, a silicon resin. Silicone resin is suitable because it has excellent flexibility and heat insulating properties. The back surface side of the heat insulating pad 30 corresponding to the outside of the clothes is covered, and a hole 31 for joining the metal plate 19 to the joint portion 21 of the heat exchange plate 20 is formed on the back surface side thereof. The hole 31 is a hole having substantially the same size as the outer size of the metal plate 19. Therefore, the metal plate 19 fixed to the holding member 18 can be joined to the joint portion 21 of the heat exchange plate 20 held by the heat insulating pad 30 through the hole 31. Further, on the back surface side of the heat insulating pad 30, a tubular fixing portion 32 that engages with the engaging projection 42 provided on the fixing pad 40 is provided at three positions of the upper part and the lower part.

On the other hand, the front side (inside of clothes) of the heat insulating pad 30 is open so as to expose the heat exchange plate 20 as shown in FIG. 1 (b), and the peripheral edge portion of the heat exchange plate 20 is held at the peripheral edge portion thereof. A holding portion 33 is provided. That is, the heat insulating pad 30 holds the heat exchange plate 20 in a state of covering the peripheral portions on the back surface side and the front surface side of the heat exchange plate 20. By covering the back surface side of the heat exchange plate 20 corresponding to the outside of the clothes, the heat insulating pad 30 satisfactorily causes heat absorption by the heat exchange plate 20 toward the user's body and can prevent heat exchange loss.

The fixing pad 40 is, for example, a resin pad, and is a pad fixed to a heat insulating pad 30 arranged from the outside of the clothes 100 to the inside of the clothes 100. The fixing pad 40 is formed, for example, having substantially the same shape as the heat insulating pad 30. The fixing pad 40 is formed with a hole 41 having a size slightly larger than the outer shape of the fan cover 11, and the fan cover 11 is attached so as to project from the fixing pad 40 to the outside of the clothes through the hole 41. Further, on the inner surface of the clothes of the fixing pad 40, the above-mentioned engaging protrusion 42 is provided at a position corresponding to the fixing portion 32 of the heat insulating pad 30. For example, the fixing pad 40 is fixed to the heat insulating pad 30 by fitting the engaging protrusion 42 into the fixing portion 32 of the heat insulating pad 30. At this time, the clothes 100 are arranged in a state of being sandwiched between the heat insulating pad 30 and the fixing pad 40. As a result, the air conditioning unit 1 is attached to the fabric 101 of the back body of the garment 100 as shown in FIG. Since the engaging protrusion 42 has a structure in which it is fitted into the tubular hole of the fixing portion 32 and is in an engaged state, it is not only easy to attach but also can be easily removed.

FIG. 4 is a diagram showing a cross-sectional structure of the air conditioning unit 1 mounted on the garment 100. The air conditioning unit 1 cools or heats the body 200 of the user wearing the clothes 100 by supplying a direct current to the Pelche element 17 and driving the fan 14. When a direct current is supplied to the Pelche element 17, the Pelche element 17 causes an endothermic action or a heat generation action on one surface facing the user's body 200. This endothermic action or heat generating action is thermally conducted to the metal plate 19. The heat capacity of the metal plate 19 is smaller than the heat capacity of the heat exchange plate 20. Therefore, the Pelche element 17 can efficiently cool or heat the metal plate 19 without increasing the current consumption.

When the temperature of the metal plate 19 is lowered or raised by the endothermic action or heat generation action of the Pelche element 17, the heat is transferred to the heat exchange plate 20 via the joint portion 21. As a result, the temperature of the heat exchange plate 20 drops or rises, and the user's body 200 can be directly or indirectly cooled or heated. That is, the Pelche element 17 can cool or heat the heat exchange plate 20 via the metal plate 19. In particular, since the heat exchange plate 20 is formed by using a metal having a relatively high thermal conductivity as described above, the heat transferred from the metal plate 19 is relatively efficiently distributed to the entire heat exchange plate 20. It has become. Therefore, the air conditioning unit 1 can efficiently cool or heat a relatively wide range of the user's back with one Pelche element 17.

Further, as described above, the Pelche element 17 causes an action opposite to the above on the other surface that does not face the user's body 200. For example, when the user's body 200 is cooled, a heat generating action is generated on the surface of the Pelche element 17 facing the outside of the clothes. This heat is endothermic by the heat sink 15. When the fan 14 is driven, external air enters the fan cover 11 from the intake window 12 provided on the fan cover 11 as shown by an arrow F1 as shown in FIG. This air takes heat from the heat sink 15, becomes warm air, and is exhausted from the exhaust window 13 to the outside of the fan cover 11 as shown by an arrow F2. That is, the heat of the heat sink 15 is discharged to the periphery of the fan cover 11 from the exhaust window 13 provided at the side position of the heat sink 15.

Further, when the user's body 200 is heated, an endothermic action occurs on the surface of the Pelche element 17 facing the outside of the clothes. This heat is also endothermic by the heat sink 15. Then, the air entering the fan cover 11 from the intake window 12 by the fan 14 takes the heat of the heat sink 15, becomes cold air, and is exhausted from the exhaust window 13 to the outside of the fan cover 11.

The air conditioning unit 1 cools or heats the user's body 200 as described above. In particular, when the air conditioning unit 1 is attached to the clothes 100 for the purpose of cooling in the summer, the skin temperature of the body 200 is about 33 ° C., whereas the temperature of the metal heat exchange plate 20 is lower than the skin temperature. There are many. Therefore, when the body 200 touches the heat exchange plate 20 when wearing clothes, a certain cool feeling can be given to the user. However, the cool feeling obtained when wearing clothes is temporary, and when the Pelche element 17 is not driven, the heat exchange plate 20 gradually rises to the same temperature as the skin temperature of the body 200. ..

On the other hand, when the Pelche element 17 is driven immediately after clothing, the Pelche element 17 starts to cool the heat exchange plate 20 before the temperature of the heat exchange plate 20 starts to rise. Therefore, the temperature rise of the heat exchange plate 20 can be suppressed. That is, when it is used for the purpose of cooling in summer, the Pelche element 17 may absorb the heat of the heat exchange plate 20 so as to suppress the temperature rise of the heat exchange plate 20. Therefore, the above-mentioned air conditioning unit 1 has an advantage that the user can be given a cool feeling from the time of wearing without increasing the power consumption of the Pelche element 17, and the cool feeling can be continued for a long time. There is.

The clothes 100 to which the air conditioning unit 1 is attached may be summer clothes or winter clothes. For example, as shown in FIG. 4, the clothing may be the outermost clothing worn by the user. Further, for example, as shown in FIG. 5, the air conditioning unit 1 may be attached to the clothes 100 worn inside the outerwear 150. However, as shown in FIG. 5, when the jacket 150 is present on the outside of the air conditioning unit 1, when the fan 14 is driven, the intake window 12a provided on the bottom 11a of the fan cover 11 is covered with the jacket 150. Therefore, sufficient air cannot be taken into the inside of the fan cover 11 from the intake window 12a of the bottom portion 11a. Therefore, the air conditioning unit 1 of the present embodiment is provided with an intake window 12b not only on the bottom portion 11a of the fan cover 11 but also on the peripheral wall 11b. As shown in FIG. 5, the intake window 12b is formed on the peripheral wall 11b of the fan cover 11 at a position closer to the bottom portion 11a than the lateral position of the fan 14, and is formed on the upstream side of the air flow generated by the fan 14. ing. Therefore, when the fan 14 is driven, it is possible to take in external air into the inside of the fan cover 11 from the intake window 12b formed at a position close to the bottom portion 11a. Therefore, even if the jacket 150 is attached to the intake window 12a of the bottom portion 11a, air is taken into the inside of the fan cover 11 from the intake window 12b formed on the peripheral wall 11b, and the heat sink 15 is contacted. Can supply sufficient air.

Further, in the present embodiment, as shown in FIGS. 4 and 5, the fan cover 11 is formed so that the internal angle θ at the connection portion between the bottom portion 11a and the peripheral wall 11b is equal to or less than a right angle. By forming the internal angle θ of the connection portion between the bottom portion 11a and the peripheral wall 11b at a right angle or less, even if the jacket 150 is attached to the bottom portion 11a as shown in FIG. 5, the jacket 150 A space S can be formed between the peripheral wall 11b and the peripheral wall 11b. That is, by forming a space S in the vicinity of the peripheral wall 11b on which the intake window 12a is formed, air can enter the fan cover 11 from the intake window 12b formed on the peripheral wall 11b as shown by an arrow F1. It will be possible. As a result, sufficient air can be taken in from the intake window 12b to remove heat from the heat sink 15. The air that has become warm or cold by removing heat from the heat sink 15 is exhausted from the exhaust window 13 to the outside of the fan cover 11 as shown by an arrow F2. This exhaust gas mixes with the outside air inside the jacket 150, becomes air at room temperature, and is taken into the fan cover 11 again from the intake window 12a. That is, the air conditioning unit 1 of the present embodiment has the intake window 12b and the exhaust window 13 provided on the peripheral wall 11b of the fan cover 11 even when the coat 150 is layered on the outside of the clothes 100. By circulating air inside the coat 150, it is possible to suppress an excessive temperature rise or fall of the heat sink 15, and to maintain a good cooling effect and a heating effect.

For example, when the clothes 100 to which the air conditioning unit 1 is attached are worn for the purpose of cooling in the summer, and the outerwear 150 is further worn on the outside thereof, the air exhausted from the exhaust window 13 becomes warm. In this case, since the cooling capacity can be increased more than the heat absorption amount of the heat sink 15 by increasing the air volume of the fan 14, the warm air exhausted from the exhaust window 13 does not warm the air inside the jacket 150. That is, the skin temperature of the user's body 200 is about 33 ° C., and the skin temperature does not exceed about 36 ° C. even when the influence of the outside air temperature and the kinetic energy is taken into consideration. The relationship between the wind speed and the sensible temperature is that the sensible temperature drops by about 1 ° C at a wind speed of 1 m / sec. Can be cool. Therefore, for the purpose of cooling, the wind speed of the fan 14 may be set to 2 m / sec or more.

Further, the fan cover 11 may adopt a structure that partially increases the wind speed of the fan 14. For example, as shown in FIG. 6, an air flow having a substantially circular cross section inflated at least inside the fan cover 11 at the tip of the edge of the intake window 12b provided near the bottom portion 11a of the peripheral wall 11b at a position close to the heat sink 15. A structure provided with the forming portion 11c may be adopted. The airflow forming portion 11c shown in FIG. 6 is formed at the edge portion of the opening edge forming the intake window 12b at a position close to the heat sink 15, and has a shape inflated in a substantially circular cross section inside and outside the fan cover 11. have. However, the shape of the airflow forming portion 11c is not limited to this, and may be a shape inflated only inside the fan cover 11. Further, the distance between the airflow forming portion 11c and the fan 14 is preferably about 3 mm or less. By providing such an airflow forming portion 11c at the edge of the intake window 12b, an airflow F1a is formed in the vicinity of the airflow forming portion 11c. Due to the Venturi effect, the airflow F1a has a higher wind speed than the airflow flowing through other parts. As a result, the amount of air flowing into the inside of the fan cover 11 through the intake window 12b increases. That is, the air volume can be increased by the capacity of the same fan 14. Then, as described above, the venturi effect can be enhanced by setting the gap between the airflow forming portion 11c and the fan 14 to a gap of about 3 mm or less, and the amount of air sucked from the intake window 12b can be effectively increased. can.

Further, it is preferable that the opening width of the exhaust window 13 is substantially the same as the height of the fins 16 provided on the heat sink 15.

(Modification example)
Although one embodiment of the present invention has been described above, the present invention is not limited to the contents described in the above-described embodiment, and various modifications can be applied.

For example, in the above embodiment, the air conditioning unit 1 capable of switching between cooling and heating has been described, but the present invention is not limited to this. For example, the air conditioning unit 1 may be a cooling unit or a heating unit.

Further, in the above embodiment, the air conditioning unit 1 for cooling or heating the back of the user has been described as an example. However, the part of the body 200 where the air conditioning unit 1 cools or heats is not necessarily limited to the back of the user.

Further, in the above embodiment, the case where the fan cover 11 has a bottomed cylindrical shape having a bottom portion 11a and a peripheral wall 11b is exemplified. However, the shape of the fan cover 11 is not necessarily limited to the cylindrical shape. For example, the fan cover 11 may have a bottomed tubular shape as a whole, and may have a prismatic shape, a truncated cone shape, a prismatic trapezoidal shape, or a mixed shape thereof. ..

Further, when the coat 150 is present on the outside of the air conditioning unit 1, the fan cover 11 forms a space S in the vicinity of the peripheral wall 11b as described above, and air flows into the inside of the fan cover 11 from the intake window 12b.
