Description

The present invention relates to a portable temperature control device.

If you have to wear clothing despite the high temperatures, for example if the temperature is high in a nuclear facility and you have to wear protective clothing to prevent exposure, or if the motorcycle driver is in the hot summer months When driving a motorcycle wearing a jumpsuit, it is necessary to cool the body efficiently.

On the other hand, if the temperature is low but you cannot wear warm clothes, for example, if the worker works in a freezer warehouse, or if you have to work outdoors in the cold winter, you should wear your body. It is necessary to heat efficiently.

To meet these needs, a tube is sewn onto the garment, a cooling medium is passed through the tube, and the cooling medium is cooled by a cooling device equipped with an evaporator, a compressor, an aggregator, a pump, and a microcomputer.

The clothing body 11 is formed of a cloth such as cotton, nylon, or polyester. The clothing body 11 includes, for example, an inlet jack 12A and an outlet jack 12B of the clothing body tube 12 at a portion corresponding to the waist.

The clothing body tube 12 is attached so as to meander along the surface of the clothing body 11. The clothing body tube 12 may be formed by one tube, but it is desirable to have a tube that branches from one tube connected to the inlet jack 12A in order to improve the cooling efficiency.

When the clothing body tube 12 has a plurality of branched tubes, each tube has the same length, and each tube is installed at a different part of the clothing body. For example, the clothing tube 12 reciprocates left and right or up and down to different parts such as around the right neck, around the left neck, right chest, left chest, right flank, left flank, right back, left back, and so on. Be placed.

When arranged in this way, the temperature in the vicinity of the inlet jack 12A and the temperature in the vicinity of the outlet jack 12B do not differ significantly, and the temperature of the body can be adjusted more uniformly.

The temperature control unit 2 is attached to the clothing unit 1 by an appropriate method. For example, the temperature control unit 2 may be attached like a rucksack, a shoulder bag, a hip bag, an arm pouch, or a leg pouch that is carried on the back by using a belt. Alternatively, it may be in a portable form such as a carry back.

As shown in FIG. 2B, the size of the temperature control unit 2 can be carried on the back or can be carried like a carry back, and does not interfere with the physical exercise and work of the wearer of the clothing unit 1.

For example, if the purpose is cooling, the cooled cold insulation material will generate heat, and if the purpose is heating, heat will be generated from a metal container containing hot water, a disposable body warmer, or a combination of a heater and a replaceable power pack. Wood can be used. When the cooling body 24 is a combination of a heater and a replaceable power pack, the replaceable power pack may be externally attached. The cold body 24 is selected from one of a cold insulating material and an exothermic material.

The cold insulation body 24 is removable, and when the cold insulation body 24 is a cold insulation material, the warm cold insulation material can be removed from the temperature control unit 2 and replaced with the cold insulation material 24. Further, when the cold body 24 is a metal container containing hot water, the metal container can be taken out and the hot water can be replaced. If the cold body 24 is a disposable body warmer, it can be replaced with a new disposable body warmer. When the cooling body 24 is a combination of a heater and a replaceable power pack, the power pack can be taken out and replaced with a new power pack, or if the power pack is a rechargeable battery pack, the rechargeable battery pack can be charged.

As shown in FIG. 3, the cold body 24 is arranged so that one surface is in contact with the medium tube 23 and the other surface is in contact with the medium pack 25. That is, the medium tube 23 and the medium pack 25, which are the first medium transport paths, are arranged along the outer surface of the cold body 24 so that the medium can exchange heat with the cold body 24.

The first medium transport path is selected from one or more of a tubular body (tube) arranged so as to meander on the outer surface of the cold body 24 and a bag-shaped body arranged on the outer surface of the cold body 24. When the first medium transport path is a bag-shaped body, the first medium transport path is formed in a flat shape according to the shape of the cold body 24.

Further, the first medium transport path is among a tubular body arranged so as to spirally orbit the outer surface of the cold body 24 and a bag-shaped body arranged so as to spirally orbit the outer surface of the cold body 24. One or more types may be selected from.

As the pump 27, for example, a tube pump or a diaphragm pump can be used regardless of the type.

As shown by the white arrows in FIG. 3, the medium returned from the covering portion 1 reaches the pump 27 via the first suction tube 22, the medium tube 23, the medium pack 25, and the second suction tube 26, and reaches the pump 27. Refluxes the sucked medium back to the clothing portion 1 via the discharge tube 28.

That is, the pump 27 communicates between the first medium transport path and the subject to be temperature controlled, in this case the clothing tube 12 which is the second medium transport path arranged around the human body. Circulate the medium so that it circulates in a closed manner.

The first medium transport path and the second medium transport path are detachably connected by a connection such as a jack. Therefore, the user can attach / detach the temperature control unit 2 while wearing the clothing unit 1.

As shown in FIG. 4B, the case 30 has a substantially trapezium shape in which the lid portion 33 corresponds to the upper base, and the upper base and the trapezium-shaped legs are connected by a rounded shape in a plan view. This is to prevent the case 30 from getting caught in an object during work.

As described above, the portable temperature control device of the present embodiment exchanges heat between the medium for transferring heat, the removable cold body 24 for adjusting the temperature of the medium, and the cold body 24. The medium is arranged around the first medium transport path (medium tube 23 and medium pack 25) arranged along the outer surface of the cold body 24 and the object to be adjusted (body) to be temperature-controlled, and the medium is the first.
