Description

The present invention relates to an air-conditioned garment that can maintain a comfortable environment inside the garment because the feeling of heat is suppressed, and is excellent in wearing comfort and design even in a wearing scene such as an office or a home.

As a measure against global warming, raising the set temperature of the air conditioner in the summer and lowering the set temperature of the air conditioner in the winter are one of the effective means for reducing carbon dioxide emissions. However, when the temperature of the air conditioner is changed, the comfort in the indoor space such as an office or a residence is lowered, and especially in the summer, it becomes a problem that the stickiness due to sweating causes discomfort. Therefore, clothes have been proposed for maintaining comfort by sending outside air into the clothes by using a fan.

For example, clothes that cool the body by blowing the outside air taken in by a fan between the outer material and the lining of the clothes have been proposed (see Patent Document 1). According to the technique, by attaching the lining, it is possible to forcibly generate an air flow between the outer material and the lining, and the body can be cooled.

Further, there has been proposed a garment in which a flow rate of air corresponding to the weight of the wearer and the working environment is circulated to promote the vaporization of sweat and cool the body (see Patent Document 2). According to the technique, the vaporization of sweat can be promoted by setting the flow rate of air to an appropriate flow rate according to individual differences such as the weight of the wearer and the purpose of use.

Further, a garment has been proposed in which air is flowed through a flow passage formed by a spacer inside the garment to cool the body (see Patent Document 3). According to the technique, the sweat can be vaporized and the body can be cooled by bringing the circulating air into contact with the sweat.

JP-A-2018-168485 International Publication No. 2005/063065 International Publication 2003/1032424

According to the technique disclosed in Patent Document 1, since the garment has an outer material and a lining, it is possible to forcibly generate an air flow in the space between the outer material and the lining by a fan to cool the body. is there. However, in everyday wearing scenes such as offices and homes, the space between the outer material and the lining becomes bulky due to the outside air taken in, and the clothes swell and impair the design, and the fabric is used as the outer material to create the space inside the clothes. It was indispensable to have a double structure of lining and lining, and the problem was that the feeling of heat when the fan was stopped was high.

Further, according to the technique disclosed in Patent Document 2, it is possible to promote the vaporization of sweat by setting the flow rate of air to an appropriate flow rate according to individual differences such as the weight of the wearer and the purpose of use. .. However, in everyday wearing scenes such as offices and homes, the amount of outside air taken in to promote the vaporization of sweat causes the clothes to swell and impair the design, and when a small fan is used, the air flow path is blocked. A spacer was required to secure it, and the problem was that it was inferior in comfort when worn.

Further, according to the technique disclosed in Patent Document 3, it is possible to vaporize sweat and cool the body by circulating air through the air flow passage inside the clothes. However, in everyday wearing scenes such as offices and homes, the air flow passage swells due to the outside air taken in and impairs the design, and spacers are provided to secure the air flow path when worn. The problem was that it was inferior in comfort.

The subject of the present invention solves the above-mentioned technical problems, and since the feeling of heat is suppressed, the environment inside the clothes can be kept comfortable, and the wearing comfort and design can be improved even in the wearing scene such as office or home. The purpose is to provide excellent air-conditioned garments.

As a result of the study by the present inventors, when the blower unit is attached to clothes made of a soft and flexible material, the bellows effect is promoted, so that the body is efficiently cooled even with a relatively small air volume. I got the finding that it is possible to do it. In addition, when a relatively heavy blower unit is attached to a thin shirt that is intended to be worn in the office or at home, the comfort of wearing it is significantly reduced because the clothes hang down and cannot form a space that serves as an air passage. It turned out to be.

Therefore, as a result of diligent studies, the present inventors set the flexural rigidity, the amount of ventilation, and the total weight of the ventilation unit within a certain range to efficiently exhibit the wiping effect. It has become possible to suppress a decrease in design due to swelling of clothes, and it has been found that the air-conditioned clothes have excellent wearing comfort and design even in a wearing scene such as an office or a home, and the present invention has been completed.
