<p>PURPOSE:To provide the optimum bed condition according to the elapsed sleeping time, by providing a variable temperature and humidity device which can variably change the temperature and humidity in the bed and conducting the feedback control in accordance with the detected temp. and humidity in the bed by the variable device. CONSTITUTION:A bed 1 is provided with an air blower mat 9 thereunder. A hot blow unit 5 and an air filter 6 are attached at the corner of the air blower mat 9. The temperature and humidity in the bed 1 are varied by the actuation of the hot blow unit 5. A temperature sensor 3 and a humidity sensor 4 are parallelly arranged in a line at the nearby position of a person's back on the bed and the detected signals are input in a control circuit 7. Further, an air conditioner 14 is installed in order to adjust a warm environment in the bed room. When the temperature of the sensor 3 reaches 30 degree C or more and rises at a higher rate than 0.5 deg.C per 5 minutes, it is judged that someone is in the bed. When nobody is in the bed, preliminary heating in winter or preliminary cooling in summer is done. When someone is in the bed, the heater 2 or the hot blow unit 5 is feedback-controlled in accordance with the detected temperature or humidity.</p> |
