Description

Blower unit for air-conditioned garment and air-conditioned garment

The present invention includes an air-conditioning garment blower unit and the unit, which can maintain a comfortable environment inside clothes because the feeling of heat is suppressed and are excellent in wearing comfort and design even in a wearing scene such as an office or a home. It is related to air-conditioned clothing.

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, a garment has been proposed in which the temperature inside the garment can be controlled by blowing outside air into the garment by a blower unit including a fan (see Patent Document 1). According to the technique, even if the work tool is attached, the outside air can be rationally blown into the clothes in a convenient and rational manner.

Further, a garment has also been proposed in which air is blown into a space inside the garment from a blower held in a holding portion such as a pocket and the outside air is guided to a desired region via the space inside the garment (see Patent Document 2). According to the technique, since the outside air can be supplied to individual parts via the internal space, it is possible to limit the cooling to the region where the wearer does not need cooling.

Further, a blower for in-clothing ventilation that promotes the evaporation of sweat by flowing an inspiratory flow near the skin has been proposed (see Patent Document 3). According to the technique, the part of the body where the user feels hot air can be arbitrarily ventilated, and the climate inside the clothes can be made comfortable.
