Temperature-controlled air circulation type bedding

Abstract

Provided is temperature-controlled air circulation type bedding which introduces the blowoff air generated by temperature control unit into an air flow passage provided around a bedding body so as to cool or warm the body of a person in the bedding, controls the blowoff air temperature to form a comfortable sleeping environment irrespective of an external atmosphere temperature, suppresses discharge of carbon dioxide gas, etc. with a compact configuration, and has low power consumption. The temperature-controlled air circulation type bedding includes a temperature control unit 2 which controls the blowoff air temperature by a cooling or heating action, and a bedding body 3 which provides an air flow passage 27 which allows the blowoff air from the temperature control unit to be introduced and circulated therethrough, and cools or warms the inside thereof. The temperature of air which circulates through the bedding is detected so that the temperature of the blowoff air is controlled by the temperature control unit.
