Abstract

PURPOSE:To control the inside of bed during sleep at a suitable temperature regardless of the change of a condition of bedclothes due to types of bedclothes or turning over, etc., by controlling a cooler/heater in response to a detecting signal of an in-bed temperature detecting device. CONSTITUTION:When a selective switch 13 is set at automatic, and a cooler/ heater 3 is operated, if a user is not in bed, a room temperature is detected by a room temperature detecting device 11 just like a normal air conditioner, and it is controlled so that this value would approach to a set value by a slide volume control knob 14 for room temperature setting. If the user gets into bed, a human body detecting device 10 operates, and it is switched over to in-bed operation. That is, an in-bed temperature is detected by an in-bed temperature detecting device 6, and it is controlled so that this value would approach a set value by a slide volume control knob 15 for in-bed temperature setting. Also, when the selective switch 13 is switched over to manual, regardless of the human body detecting device 10, in-bed operation and out-of-bed operation can be manually switched over. Therefore, even when a sleeping person and staying-up person stay in the same bedroom, it can be freely switched over.
