Under the work environment as described above, it is substantially difficult to secure a comfortable work environment temperature by air-conditioning the temperature of the entire room as in a general office office or store. For this reason, the thing which can provide cooling / heating only with respect to an operator, with the whole temperature and ambient temperature as it is is desired.

In this respect, in the winter, gas heaters using a cassette type gas cylinder, portable pocket warmers, and the like are often used as stationary or mobile portable spot heating. However, although it is a portable spot, gas heating accompanied by combustion cannot be used in an environment where the use of fire is prohibited, and the surrounding temperature also increases. Also, in work involving frequent movement, it is expected that carrying and transporting will be complicated.

Also, in summer, so-called heat countermeasures are taken using a neck cooler made of a cloth containing water so as to lower the body temperature by the heat of vaporization of water, a frozen coolant, or the like. However, compared with cooling, spot coolers, electric fans, etc., the cooling effect is extremely limited, and there are aspects that cannot be said to sufficiently reduce the heat of the operator. When working at a certain place for a certain amount of time, a mobile spot cooler is also used, but this greatly affects the ambient temperature indoors, and in work involving frequent movements. Because of its low portability, it is virtually impossible to use. In other words, it would be desirable if there was something like work clothes with an air-conditioning function, also called personal air-conditioning.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a clothing air-conditioning unit with an air-conditioning function that is easily detachable and does not obstruct work.

The air conditioning unit for clothes described in the embodiment provides a cooling and heating system that allows a wearer to spend comfortably by arranging a flexible tube in which a liquid medium whose temperature is adjusted to a suitable temperature by a Peltier element is enclosed in a clothing (typically a vest). To do.

Since the Peltier element and the power source for driving the Peltier element can be attached to the waist belt or the waist belt for the safety belt, the wearer can smoothly perform the original work. In addition, the flexible tube can be arranged on the inner side of the garment and fixed by sewing or the like, and can be disconnected by a detachable connector, so that it does not interfere with the dressing operation or the undressing operation.

In the air conditioning unit for clothes described in the embodiment, the residual heat generated in the Peltier element is effectively released into the air by the heat transfer member and the blower fan that support the appropriate inflow of air that exhausts the residual heat. It becomes. Further, by arranging the heat transfer member and the heat radiating fin so as to sandwich the blower fan, it is possible to efficiently exhaust heat. Therefore, the air conditioning unit for clothes according to this embodiment will be described below with reference to the drawings.

FIG. 1 is an overall schematic diagram illustrating a clothing air conditioning unit 1000 according to the present embodiment. In FIG. 1, the clothing air conditioning unit 1000 includes a rechargeable battery unit 1100 including a rechargeable battery case 1110 that can be attached to a belt and a rechargeable battery 1120 set in the rechargeable battery case 1110. By configuring the rechargeable battery 1120 to be detachable from the rechargeable battery case 1110, it is convenient because only the main body of the rechargeable battery 1120 can be replaced or charged while the rechargeable battery case 1110 remains attached to the belt. The battery 1120 itself may be attached to the belt.

The clothing air conditioning unit 1000 also includes a stabilized power supply 1200 that stabilizes the electric power output from the rechargeable battery 1120 to an appropriate electric power for the Peltier element. The stabilized power supply 1200 is preferably provided from the viewpoint of improving power efficiency and temperature control efficiency, but may be omitted.

In addition, the clothing air conditioning unit 1000 includes a temperature control unit 1300 that is driven by power from the stabilized power supply 1200. The temperature control unit 1300 is housed in a housing such as a box (not shown) (for example, an aluminum box) and is configured as a temperature control box. Thereby, it can prevent that dust etc. adhere to various electronic parts contained in temperature control part 1300, or a tool etc. touch and are damaged. A box, a case, and the like are appropriately provided with slits, spaces, and the like that allow air to flow in and out.

The clothing cooling / heating unit 1000 includes a flexible tube 1410 that sends liquid refrigerant from the temperature control unit 1300 to the vest 1500, and a flexible tube 1420 that returns liquid refrigerant from the vest 1500 to the temperature control unit 1300. A pair of flexible tubes 1400 are provided.

The flexible tube 1410 includes a detachable connector 1450 between the vest 1500 and the temperature control unit 1300. The flexible tube 1420 includes a detachable connector 1460 between the vest 1500 and the temperature control unit 1300. The detachable connectors 1450 and 1460 have a sealing structure that prevents the liquid in the tube from leaking at the time of detachment. However, since the structures and configurations that are already widely known can be used, description thereof will be omitted.

The flexible tube 1400 is appropriately arranged by sewing inside the vest 1500, and is configured so that the body temperature of the wearer of the vest 1500 can be appropriately adjusted. When dressing or undressing the vest 1500, the detachable connectors 1450 and 1460 are removed, so that the flexible tube 1400 is disconnected without leaking the liquid refrigerant, thereby enabling a smooth changing operation. In FIG. 1, the flexible tube 1410 extended from the temperature control unit 1300 is provided with a thermometer 1600 that measures the temperature of the liquid refrigerant, but may be omitted.

FIG. 2 is a diagram illustrating a state where the flexible tube 1400 is disposed inside the vest 1500. In FIG. 2, a flexible tube 1400 is arranged from the back side of the vest 1500 to both shoulders and upper arms, and is fixed with sewing threads. FIG. 2 shows a typical example, and the flexible tube 1400 can be arranged and fixed at an arbitrary position.

3 and 4 are diagrams illustrating the configuration of the temperature control unit 1300 mounted in the temperature control box. As can be understood from FIGS. 3 and 4, the temperature control unit 1300 includes a circulation pump 1370 to which a flexible tube 1400 is connected to circulate a liquid medium, a Peltier element 1360 that is in contact with the circulation pump 1370, and a Peltier element. And a heat insulating material 1350 covering the periphery of 1360 with the same thickness as the Peltier element. The heat insulating material 1350 supplements a gap generated by the difference in size between the contact surface of the Peltier element 1360 and the surface of the circulation pump 1370 and prevents heat from being dissipated from the gap.

As shown in FIGS. 3 and 4, an aluminum heat transfer member 1340 is disposed in contact with the upper surface of the Peltier element 1360. The heat transfer member 1340 supports the function of quickly releasing the exhaust heat generated in the Peltier element 1360. A blower fan 1330 is arranged on the upper surface side of the heat transfer member 1340 on the paper surface, and a heat radiating fin 1310 is arranged on the upper surface side of the air blower fan 1330 on the paper surface. The blower fan 1330 sucks air from the heat transfer member 1340 side and sends it out to the heat radiation fin 1310 side.

In addition, the heat transfer member 1340 and the radiating fin 1310 are connected by a heat transfer wire 1320, and the exhaust heat is conducted from the heat transfer member 1340 to the radiating fin 1310 through the heat transfer wire 1320. 3 and 4, the heat transfer member 1340 has a form in which the center is convexly extended in one direction. FIG. 6 is a schematic diagram illustrating the shape of the heat transfer member 1340.

As shown in FIGS. 3, 4, and 6, in the heat transfer member 1340 having a convex portion 1341 extended in the first direction and a flat portion 1342, air is indicated by a thick arrow by the blower fan 1330. Flows from the edge to the center. Thereby, the exhaust heat of the Peltier element 1360 disposed in contact with the bottom surface of the heat transfer member 1340 in FIG. 6 can be effectively released to the inflowing air. Moreover, it is preferable that the heat transfer wire 1320 is disposed on an air flow path (that is, the second direction) indicated by a thick arrow in FIG. In addition, it is more preferable that the boundary between the convex portion 1341 and the flat portion 1342 be tapered and gently formed, because air resistance is reduced and a smooth air flow is formed.

In FIG. 6, the heat transfer member 1340 having the extended convex portion 1341 has been described. However, the flat portion 1342 is disposed so as to surround the central convex portion 1341, and air is evenly distributed from all sides. It is good also as what flows in. In this case, the heat transfer wire 1320 may be disposed on either the first direction or the second direction.

FIG. 5 is a diagram illustrating the detachable connectors 1450 and 1460 provided on the flexible tube 1400. FIG. 5 shows a type in which the joint is easily detached and the liquid medium inside is sealed by pressing a push button provided on the side surface of the detachable connectors 1450 and 1460. However, as the detachable connectors 1450 and 1460 having such functions, various mechanisms, shapes, and structures are known and commercially available, and any one can be selected and used.

The air conditioning unit for clothes of the present invention includes a rechargeable battery housed in a rechargeable battery case that is detachably attached to a belt (a waist belt for a safety belt, a torso belt, etc.), and a rechargeable battery that is detachably attached to the belt. A Peltier element mounted on the temperature control box, including a temperature control box to which electric power is supplied, and at least a pair of flexible tubes connected to the clothes from the temperature control box through a detachable connector The liquid medium whose temperature is adjusted by circulates between the clothing and the temperature control box through a flexible tube by a circulation pump (medium delivery motor, etc.) mounted on the temperature control box, and is applied to the garment wearer. The detachable connector is characterized in that the detachable port is sealed so that the liquid medium does not leak at the time of detachment.

Thereby, even when clothes, typically a vest, are undressed, it can be avoided that the flexible tube filled with the liquid refrigerant becomes an obstacle to undressing. During cooling and heating, the clothes and the temperature control box attached to the belt are connected to each other by “flexible” by a flexible tube.

For example, as is apparent from experience when using headphones or earphones in a wired manner, when the headphones or the like are removed from the wearing state, there are many cases where the wired wires get in the way or become twisted. In the present invention, when clothes are undressed or dressed, the so-called disconnection state can be brought about by the detachable connector, so that a smooth dressing operation or the like is possible and there is no unintentional twist. .

Even in this case, there is no concern that the liquid medium leaks from the connector. In addition, since the detachable connector which can prevent leakage of an internal liquid etc. can utilize the structure widely known as connection connectors, such as a watering hose, description is abbreviate | omitted here.

Also, by attaching various tools to the waist belt by jumping craftsmen and carpentry craftsmen, carrying these tools and carrying out various tasks with both hands free, a rechargeable battery and a temperature control box Can be worn on the waist belt. As for these mounting methods, various known methods similar to the case of mounting various tools such as hooks and snaps to the belt can be employed.

By uniformly stretching the flexible tube around the garment, the entire garment can be cooled or heated, and the wearer can feel coolness or warmth. However, the flexible tube may be intensively arranged at any specific location, for example, under the armpit or around the neck. For example, a larger number of flexible tubes may be arranged on the part of the clothes corresponding to the stomach circumference so as to warm the stomach circumference intensively.

By using the flexible tube, it is possible to flexibly cope with kinking and deformation of clothes, and there are almost no restrictions on the operation and work of the wearer. In addition, since a rechargeable secondary battery is used, the convenience is high. For example, a battery shared with the power source of various electric tools such as an electric drill and an electric driver may be used.

The air conditioning unit for clothes of the present invention is preferably further provided with a temperature control box, the temperature control box further including a heat radiation fin that supports heat radiation of the Peltier element and a blower fan that blows air to the heat radiation fin, When the temperature control box is attached to the belt, the belt is arranged in a direction other than the human body side.

The temperature control efficiency by the Peltier element is improved by the radiating fin and the blower fan that blows air to the radiating fin, so that more rapid and effective cooling or heating can be performed. Peltier elements need to dissipate the remaining heat generated during cooling, and conversely, it is necessary to absorb heat from the surrounding environment to the cold part that is the opposite of the surface that generates the necessary heat during heating. is there.

In other words, warm air is output from the outlet of the blower fan during cooling and cold air is output during heating, but such exhaust heat air is directed outward so as not to face the wearer. Become.

Such exhaust heat wind is a wind having a temperature opposite to the cooling effect and heating effect expected by the wearer, so that it is not sent directly to the wearer so that it is not sent directly to the wearer. The direction is not. This further improves the comfort of the wearer.

Moreover, the air conditioning unit for clothes according to the present invention is more preferably arranged so that one surface is in direct contact with the heat dissipation side of the Peltier element, and a heat transfer member having a convex surface on one surface, The blower fan arranged in contact with the opposite surface of the fan, and the heat dissipating fins arranged on the blower outlet side of the blower fan in order, through the heat transfer wire arranged to wrap around the outer edge of the blower fan Heat is conducted from the heat transfer member to the heat radiating fin.

As a result, the inflow of wind to the blower fan smoothly flows from the surroundings along the surface of the convex heat transfer member, and the output wind from the blower fan can effectively cool the radiating fins. it can.

The heat from the Peltier element is primarily conducted to the heat transfer member, secondly to the heat transfer wire, and thirdly to the heat radiating fin. Of these, at least the convex surface of the heat transfer member and the heat radiation fin are in direct contact with the air flowing into the blower fan and the air sent out, respectively, so that the effect of heat dissipation and the like can be improved.

In addition, when the convex surface of the heat transfer member is uniformly convex from any direction, the amount of air flowing into the blower fan is also equal regardless of the direction, so the heat transfer wire should be oriented in any direction. You may arrange.

However, when the convex surface of the heat transfer member is a convex shape that extends in the first direction and does not extend in the second direction orthogonal to the first direction (that is, a convex shape in the cut surface in the second direction). However, when the convex shape is not observed on the cut surface in the first direction), the air flowing into the blower fan mainly comes from the second direction, so it is preferable to arrange the heat transfer wire in the second direction.

In the present invention, the heat transfer member that releases unnecessary heat generated by the Peltier element and the heat dissipating fins are disposed so as to sandwich the blower fan, so that high heat dissipating efficiency can be obtained.

In particular, the fresh air flowing into the blower fan cools the heat transfer member disposed at a position closer to the Peltier element before the heat radiating fins. Can be exhausted more quickly, and high air-conditioning efficiency can be obtained.

The air conditioning unit for clothes according to the above description is not limited to the description in the embodiment, and the configuration and the operation and process are changed as appropriate within the scope of the present invention and within the scope obvious to those skilled in the art. It is something that can be done.

The present invention is suitable as an air conditioning unit for clothes that is personal and portable for an operator.
