Dry 燥開 Hajimego is by blowing means, air clothes dryer heating unit, a rotating drum, it is circulated in the path of the exhaust port to evaporate by heating the clothes of the rotary drum moisture. The water vapor evaporating from the clothes is exhausted together with the circulating air from the exhaust port of the drum and guided to the cooling and dehumidifying means. Since the cooling water is not flowing in the cooling and dehumidifying means, it is heated by the heating means through the blowing means without being cooled. Then, the relative humidity is lowered and returned to the rotating drum again. By repeating the above, the temperature of the clothes in the drum and the air in the drying path is increased, and the clothes are dried. Further, at this time, the viscosity of the water in the clothes is reduced by the heating, and the water is centrifugally dehydrated from the clothes by rotating the rotating drum at a high speed. Next, the drum is rotated at a low speed, and when the cooling water flows, the air is circulated through the heating means for drying the clothes, the rotating drum, and the exhaust port by the blowing means to heat the clothes of the rotating drum and evaporate the moisture. Let it. The steam evaporated from the clothes is filled in the drum and exhausted from the drum exhaust port together with the circulating wind, and guided to the cooling humidity means.The cooling dehumidifying means directly cools the circulating wind using the cooling water to reduce the saturated steam pressure. The excess water vapor is condensed, drained together with the used cooling water, heated by the heating means for drying the clothes to circulate the air, and returned to the drum again. In addition, by rotating the rotating drum at high speed at regular intervals during drying, the positions of the clothes are switched, and uneven drying due to the positions of the clothes is reduced. By repeating the above, the clothes in the drum are dried. Therefore, according to the first aspect of the present invention, the viscosity of the moisture in the clothes is reduced by the air heated for drying during the period from the start of drying the clothes to the time when the circulating air reaches the constant drying temperature. By spinning, the clothes are centrifugally dehydrated and a lot of water can be removed, so the amount of water in the clothes is further reduced and the drying time can be shortened, and the cooling water accompanying the shortening of the drying time can be saved. I have. Further, the flow of the cooling water is stopped immediately after the drying of the clothes is started until the temperature reaches the constant rate drying temperature, so that the temperature of the clothes and the air in the drying path are quickly increased, thereby saving water of the cooling water. Claim 2
Since the viscosity of the moisture in the clothes decreases due to the air heated to dry during the preset time from the start of drying the clothes, the clothes are centrifugally dehydrated by spinning the drum, and much moisture is As a result, the amount of water in the clothes can be further reduced, the drying time can be shortened, and the cooling water can be saved by shortening the drying time. Further, immediately after the drying of the clothes is started, the flow of the cooling water is stopped to speed up the temperature rise of the clothes and the air in the drying path, thereby saving water of the cooling water. According to the third aspect, since the amount of water contained in the clothing varies depending on the amount of clothing, the dehydration time can be shortened when the amount of clothing is small, and the dehydration time can be extended when the amount of clothing is large. . Similarly, since the time of temperature rise differs depending on the amount of clothing, it is also possible to adjust the time during which the flow of cooling water is stopped depending on the amount of clothing, so that appropriate cooling water can be saved .

冷却水の節約を図ることが出来る。 Since the drum dryer of the present invention has the above-described structure, the invention according to the first aspect of the present invention relates to a method in which the circulating air reaches a constant drying temperature from the start of drying the clothes. As the viscosity of the moisture in the clothes decreases due to the heated air to dry, by spinning the drum,
Since the clothes are centrifugally dehydrated to remove a large amount of water, the amount of water in the clothes is further reduced, so that the drying time can be shortened. In addition, the cooling water can be saved by shortening the drying time. Further, the flow of the cooling water is stopped immediately after the drying of the clothes is started until the temperature reaches the constant rate drying temperature, so that the temperature of the clothes and the air in the drying path are quickly increased, thereby saving water of the cooling water. Further, according to the invention, the viscosity of the moisture in the clothes is reduced by the air heated for drying during a preset time from the start of drying the clothes, so that the drum is dehydrated and rotated to rotate the clothes. Since the water is centrifugally dewatered to remove a large amount of water, the amount of water in the clothes is further reduced, the drying time can be shortened, and the cooling water can be saved by shortening the drying time. Further, immediately after the drying of the clothes is started, the flow of the cooling water is stopped to speed up the temperature rise of the clothes and the air in the drying path, thereby saving water of the cooling water. According to the third aspect of the present invention, since the amount of water contained in the clothing varies depending on the amount of clothing, the dehydration time is shortened when the amount of clothing is small, and the dehydration time is extended when the amount of clothing is large. be able to. Similarly, since the time of temperature rise differs depending on the amount of clothing, it is also possible to adjust the time during which the flow of cooling water is stopped depending on the amount of clothing, so that appropriate cooling water can be saved .
