PURPOSE: To constitute the air-conditioned bed so that a temperature and humidity condition is always held comfortably, a noise of the outside is cut off, bedding can be dried, it can be carried and moved by man-power, and the power consumption can be reduced by forming a system for feeding/exhausting air for controlling temperature and humidity in a vessel of a free-standing structure in which a person can sleep.

CONSTITUTION: After a person 1 lies down in a position for sleep, a door is closed to a hermetical state, an air-conditioning ventilation system 7 is operated and sucked air is blown out into a sleeping vessel 2 after temperature and humidity are controlled by using an air-conditioner 10. As for a temperature and humidity condition of the air-conditioner 10, its set condition can be maintained automatically by an air-conditioning controller 11 attached to the inside of the sleeping vessel 2. A part of the air for circulating in the sleeping vessel 2 is exhausted to the outside from an exhaust port 12 through a pipe, etc. Substitution of air in the sleeping vessel 2 is about two cubic meter per hour in the case of that for one person, therefore, the capacity of a ventilation fan 9 and the air-conditioner 10 is small, and also, a noise level is low. Moreover, a noise of the outside is cut off owing to the hermetical structure.
