ABSTRACT:
An air feeding apparatus includes an air supplying chamber disposed in a housing, and cold producing plates in the chamber, which are connected to a switching circuit controllable for changing a working mode of the plates from a cold producing one to a heat producing one. A conduit is connected to an outlet of the air supplying chamber, and sticks outside the housing. Air is forced to travel through the air supplying chamber by means of an air pump, and is guided to outside by means of the conduit; thus, the air traveling through the chamber can have temperature changed by the cold producing plates, and can be conveyed to desired locations or into other objects for use.
