Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a cooling garment having a cooling effect.

[Prior art and its problems] Conventionally, summer work clothes have been constructed to promote perspiration or ventilation by using thin fabrics or fabrics with good breathability. was.

However, even in the summer, summer work clothes for those engaged in heat work must wear a certain level of heat-resistant clothing, or when working on a telephone pole under the scorching sun.
Work clothes for electricians who must wear work clothes with a certain degree of insulation properties include work clothes made of thin or breathable fabrics such as those mentioned above that lack heat resistance or electrical insulation properties. was not suitable for that use.

In order to improve this point, work clothes have been developed that are heat resistant or electrically insulating and can provide a certain degree of cooling effect to workers.

For example, in Japanese Utility Model Publication No. 55-41773, a ventilation pipe is provided on the back side of work clothes whose outer surface is insulated with electrically insulating fibers, that is, on the side adjacent to the worker's body, and cold air is blown out from this ventilation pipe. Accordingly, a cooling insulating garment that provides a cooling effect to a worker is disclosed.

However, such work clothes not only have a complicated structure, but also necessarily include a device for generating and sending out cold air, which limits the range of movement of the worker. Even if a suitable pipe were used to communicate with the above-mentioned generation/delivery device, this pipe would restrict the movement of the operator, so it was not suitable for practical use.

[Purpose of the invention] The purpose of the invention is to solve the problems of the prior art as described above, and to provide a cooling garment that has a simpler structure and does not restrict the free movement of the worker.

[Structure of the Invention] The air-conditioning garment of the present invention includes an electronic cooling element having a heat absorption surface that generates a low temperature when energized and a heat radiation surface that generates a higher temperature than the heat absorption surface. A cooling plate having a larger area than the heat-absorbing surface is fixed to the heat-absorbing surface, and a heat-radiating plate having a larger area than the heat-radiating surface is fixed to the heat-radiating surface. The heat sink is cooled by a cooling means for cooling the heat sink.

In this way, when constructing cooling clothing,
A light and compact electronic cooling element with a large cooling capacity is used, and a cooling plate and a heat radiation plate each having a larger area than these surfaces are fixed to the heat absorption and heat radiation surfaces of the cooling element to increase the cooling area and heat radiation area. By increasing the amount of heat transfer on each surface by increasing the amount of heat transfer on each surface, and actively cooling the heat sink, it is possible to increase the cooling ability of the electronic cooling element and reduce the heat dissipation that occurs immediately after stopping electronic cooling. It is possible to prevent the temperature of the cooling plate from rapidly rising due to heat conduction from the plate to the cooling plate, causing burns to the wearer or causing a significant increase in the internal temperature of the cooling garment. Therefore, there is provided a cooling garment that is simple and compact in structure, allows free movement of the worker, and has excellent cooling effects.

[Example] FIG. 1 shows a cooling garment that is an example of the present invention.

This air-conditioned garment 1 has left and right front bodies or front parts 2 and 3, a back body or back part 4, and a pair of stoppers 5 and 6 that removably connect the left and right front parts 2 and 3. , 8:9, 10.

At the joining part between the left front part 2 and the back part 4 and the joining part between the right front part and the back part 4,
A pair of left and right shoulder openings 11 and 12 are formed, and a nape 13 is formed above the garment.

The left side stops 5, 7, 9 are fixed to the left front part 2, and the right side stops 6, 8, 10 are fixed to the left side front part 2.
is fixed to the right front part 3.

In this embodiment, each stopper is composed of an attached fastener that is easy to attach and remove, but other suitable means such as a button, a slide fastener, etc. can be used as the stopper.

Next, referring to FIG. 2 which is a back view of FIG. 1 together with FIG. 1, and FIG. It is composed of a cloth member 15 and a cooling unit 18 comprising an electronic cooling element 17 attached to the outer surface of the cloth member.

A bag-shaped pocket 19 is attached to the outer surface of the cloth member 15 on the back surface 4 by an adhesive fastener 16, and a water-absorbing sheet 20 containing water is accommodated in this pocket. Instead of the water and the water-absorbing sheet, for example, alcohol and a suitable material that absorbs the alcohol may be used as the coolant and the coolant-holding material, respectively.

The electronic cooling element 17 constituting the main part of the cooling unit 18 of the air-conditioned garment of the present invention is a well-known type such as the product name Thermo Module (Melco Asia Japan Co., Ltd.), and its outline is shown in FIG. As shown in , for the DC power supply 20,
It is composed of a pair of N-type and P-type semiconductor couples 20 and 21 that are electrically connected in series by an electric wire 21 and conductive plates 22 and 23. Therefore, in the illustrated example, the conductive Board 22
They are thermally connected in parallel so that heat emission occurs on the side of the conductive plate 23 and heat absorption occurs on the opposite side of the conductive plate 23.

High temperature due to heat release occurring on the conductive plate 22 side is transmitted to the heat dissipation surface 28 via the conductive plate 22 and insulator 26, while low temperature due to heat absorption occurring on the conductive plate 23 side is transferred to the conductive plate 23 and insulator 27. cooling surface 2 through

Both the heat dissipation plate 34 and the cooling plate 33 are made of a material with good thermal conductivity, such as iron, aluminum, or copper, and are fixed to the heat dissipation surface 28 and the heat absorption surface 29, respectively, by welding or other appropriate methods.

The heat insulating material 35 is fixed integrally between and with both plates 33, 34, and in the example shown is fixed to the fabric member 15 by means of adhesive tape fasteners 36, 37, thus covering the entire cooling unit 18. is fixed to the back.

As shown in FIG. 2, a sheet 20 of water-absorbing material is removably housed in the pocket 19 and is impregnated with water. Therefore, the heat dissipation surface of the cooling element is cooled to improve the cooling capacity of the cooling element and the heat absorption effect on the heat absorption surface of the cooling element is increased, and the heat is transferred from the high temperature heat dissipation plate to the low temperature cooling plate after electronic cooling is stopped. prevent the transmission of information. The higher the cooling capacity of the electronic cooling element, the higher the temperature of the heat dissipation surface tends to be, so the forcible cooling means as described above is required.

In the embodiment shown in FIG. 3, the inside of the fabric member 15 is provided with a layer 38 of electrically insulating material, which insulating layer extends over the entire inner surface of the inner fabric of the cooling garment and is electrically insulating. It is designed to protect construction workers from electric shock accidents. The layer 38 can also be provided on the outside or on both the inside and outside of the fabric member.

However, it will be appreciated that this insulating layer may not be necessary in other applications where there is no risk of electric shock, such as in electrical work.
