JP3242958U - Disposable cooling underwear using vaporization heat - Google Patents

Abstract

The present invention provides a disposable cooling underwear that is simple in structure and inexpensive and utilizes the heat of vaporization. SOLUTION: The underwear itself is sewn with non-woven fabric and easily transpires when sweating, but by providing a water-absorbing pad 6 that retains moisture on the back side, the water-absorbing pad can be moderately moistened before use to prevent sweating. The heat of vaporization can be used even in the front, and when sweating, the water-absorbing pad absorbs sweat and keeps it moist at all times, so the cooling effect of the heat of vaporization can be maintained for a long time. The air-conditioned clothes 14 are equipped with a cooling fan 15, and evaporate perspiration dries quickly, and the water soaked into the water-absorbing pad quickly disappears, so water must be constantly supplied. If water is supplied to the water-absorbing pad by a method using the phenomenon, it can be provided as a light, less uncomfortable, and inexpensive underwear. [Selection drawing] Fig. 9

Description

TECHNICAL FIELD The present invention relates to underwear worn under work clothes as a countermeasure against heat stroke during indoor and outdoor work.

Conventional cooling clothes include vest-type clothes that cool various parts by circulating water through ice packs and pipes. In addition, there are also cool contact underwear that uses the heat of vaporization by sewing hydrophilic and hydrophobic fabrics on the material itself.

The ice pack type cooling suit has the drawback that the ice pack is heavy, the workability is poor, and the cooling time is short. In addition, the bag that stores the ice pack is made of a vinyl material, so it is easy to sweat, and there is no place for the sweat to escape, which prevents the sweat from evaporating. Sweat that has nowhere to escape increases the discomfort index, making it easier for discomfort and heatstroke to occur. In addition, the water circulation type cooling suit requires a water tank, a pump, a battery, and the like, and is heavy when worn, placing a burden on the body. Furthermore, since the water pipes for cooling are stretched around the body, there is a drawback that it restricts the movement of the body and makes the work difficult. In contact-cooling underwear, due to the characteristics of the fabric, sweat is absorbed and dissipated quickly, so it dries easily and it is difficult to use the heat of vaporization. Therefore, a disposable cooling underwear that can be worn in layers, is light and easy to move in, has a simple structure, and utilizes the heat of vaporization is invented according to the present invention.

The present invention aims at the following (a) to (d).
(a) To provide a disposable cooling undergarment that utilizes heat of vaporization and is sewn from a non-woven fabric and provided with a pocket for inserting a water-absorbing pad on the back of the undergarment.
(b) To provide a disposable cooling undergarment utilizing heat of vaporization, in which a water absorbing pad to be inserted is formed in a felt-like shape made of rayon and polypropylene, and has water absorption, water retention and durability.
(c) To provide a disposable cooling undergarment utilizing heat of vaporization, which, when used, soaks a water-absorbing pad in water to soak it in water, then appropriately drains the water, wears it, evaporates the retained water before sweating, and evaporates the water by absorbing the sweat when it is dry.
(d) To provide a disposable cooling undergarment utilizing heat of vaporization, which requires wind to utilize the heat of vaporization, and is based on combined use of a fan-type cooling suit or a Peltier-type cooling unit.

In order to solve the above problem, a pocket for inserting a water-absorbing pad is arranged around the shoulder blade of the back of the underwear made of non-woven fabric, the water-absorbing pad is moderately moistened with water, and the air from the fan is made to efficiently touch the water-absorbing pad.

The invention related to claim 1 is characterized in that a thin non-woven fabric is used as a material constituting the underwear, and moisture is smoothly evaporated during perspiration.

The undergarment is characterized by having a pocket for storing a water absorbing pad on the back side.

The pocket-like bag for storing the water absorbing pad is characterized by having a maximum width of about 27 cm and a maximum vertical height of about 30 cm so as to cover the shoulder blades from a position about 5 cm below the neck at the maximum.

The material of the water absorbing pad is formed in a felt shape with a ratio of rayon 80% and polypropylene 20%, and the thickness of the fabric is about 2 mm.

A device related to claim 2 is characterized in that pockets capable of storing two water-filled bags made of vinyl spout pouches are provided on the left and right sides of the front surface of the underwear.

The water-filled pouch is characterized in that a water-absorbing tube made into a rod shape by weaving cotton fabric in piles is attached to each of the two water-filled pouches, and sewn to the left and right of the water-absorbing pad on the back.

FIG. 1 shows a rear view of a disposable cooling undergarment, in which a pocket 2 for inserting a water absorbing pad is provided on the back of a disposable undergarment 1 made of non-woven fabric. This water absorbing pad 3 is used after being moistened with water in advance.

FIG. 2 is a dimensional diagram showing the attachment position of the pocket 2 into which the water absorbent pad 3 attached to the back is inserted. Starting from a position 4 at a maximum of 5 cm below the neck, the height direction 5 is formed vertically up to 30 cm, and the width 6 is formed with a maximum width of 27 cm so as to cover the scapula.

FIG. 3 is a schematic diagram of the absorbent pad 3, which is made of felt-like cloth with a thickness 6 of about 2 mm, cut to a size that allows the absorbent pad to fit in the insertion pocket 2. FIG.

FIG. 4 is a view of the disposable cooling underwear 1 from the front. This type is for contact cooling using a Peltier element, and the wind speed of the fan is not so high. Compared to the fan type, the amount of sweat that evaporates is small.

FIG. 5 shows a disposable cooling underwear 1 to be worn under a fan-type air-conditioning suit 13. In the fan-type, the wind speed of the fan is high and the transpiration consumption of water is large. The water which moistened the water absorbing pad 2 at the initial stage cannot cover it, and it is necessary to pour water so that the water absorbing pad 3 does not dry out.

Claims (2)

The disposable cooling underwear is characterized in that although the underwear itself is sewn with non-woven fabric and easily transpires when perspiring, a water-absorbing pad that retains moisture is provided on the back side, and by moistening the water-absorbing pad appropriately before use, the heat of vaporization can be used even before sweating, and the cooling effect due to the heat of vaporization can be maintained for a long time by keeping the water-absorbing pad absorbing sweat when perspiring and always keeping it moist. Air-conditioned clothing is provided with a cooling fan, evaporating perspiration dries quickly, and water permeated in a water-absorbing pad quickly disappears, so that water must be constantly replenished, but if water is stored in a pouch and water is replenished to the water-absorbing pad by a method utilizing capillary action of a water-absorbing tube, the disposable cooling underwear can be provided as light, less uncomfortable, and inexpensive underwear.
