Therefore, the fan can be turned on and off. By returning, the temperature converges to a constant value as a whole.
  • the adjustment can be made by appropriately changing the ratio of the time to turn the fan on and the time to turn it off.
  • the air-cooled clothing of this embodiment uses high-density cotton cloth, even if the wearer performs light work and sweats, the sweat is easily absorbed by the high-density cotton cloth that is closer to the skin. Or through it and into between two high density cotton cloths. This moisture is easily carried out to the outside by the air flowing through the flow passage, which encourages the worker to further sweat, and the body is cooled by absorbing the heat of vaporization caused by the sweat. Therefore, the worker feels cooler and can spend more comfortably.
  • the above embodiment can be variously modified within the technical scope of the invention.
  • the type without the arm portion was used.
  • the type having the arm portion or only the arm portion is used. Needless to say, those which can be removed are also included in the scope of the present invention.
  • the fan 402 is provided at the lower part of the back.
  • the position of the fan is not limited to this, and the fan can be provided at an appropriate position according to the application.
  • the air taken in by the fan 402 does not necessarily have to be distributed throughout the air-cooled garment, and depending on the application, for example, the flow passage may be limited to only the chest and the back.
  • the surface of the human body Cooling and comfort can be obtained simply by making the temperature near the room equal to room temperature.
  • power consumption is extremely low compared to air conditioners, etc., so even if this air-cooled garment spreads widely, the power consumption of society as a whole can be reduced, resulting in the current consumption of fossil fuels. And reduce global warming.
  • the present invention is based on the principle that the heat of the body is absorbed by circulating the surrounding air near the surface of the body and forcibly increasing the temperature gradient near the body surface. It can be applied to bedding for ensuring comfortable sleep at night when it is difficult to sleep at high temperatures, and to clothing that can be comfortably used even in a high-temperature environment.

Abstract

La distribution de la température de l'air autour d'un corps humain est telle que la température de l'air est supérieure à la température de l'air ambiant au voisinage de la surface de corps et diminue graduellement de manière proportionnellement inverse à la distance qui la sépare de la surface du corps pour se rapprocher de la température ambiante, étant donné que l'air situé au voisinage de la surface du corps humain est chauffé par la température du corps. Un gradient de température à proximité de la surface du corps peut être augmenté si l'on ventile l'air ambiant avec une température inférieure à la température du corps sur une partie située au voisinage de la surface corporelle pour obliger à descendre jusqu'à la température ambiante naturelle la température de l'air située très près de la surface corporelle. Plus le gradient de température est élevé, plus le flux de chaleur est actif. Des passages de ventilation d'air sont prévus dans un dessus de lit, un futon, un oreiller ou des vêtements, qui sont portés ou utilisés pour dormir, ces passages servant à ventiler de l'air ambiant dont la température est inférieure à celle du corps. Ceci assure un gradient de température amélioré à proximité de la surface corporelle et, par conséquent, un meilleur effet de rayonnement. Même pendant un été très chaud, la température ambiante inférieure à la température du corps donne une sensation de fraîcheur.
