WARM-AIR HEATING APPARATUS

PROBLEM TO BE SOLVED: To provide a warm-air heating apparatus capable of satisfactorily performing warm-air heating even if a deodorizing filter or a sterilizing filter is clogged. SOLUTION: This warm-air heating apparatus comprises an apparatus body 1 having a warm-air outlet 3 and an air inlet 6, a fan guard 7 with air permeating surface part 39 which is installed in the air inlet 6, and either or both of the deodorizing filter 41 and the sterilizing filter 43 which are installed on the inside or outside of the fan guard 7 through air flow clearances 44 and 45 formed in the clearance thereof from the air permeating surface part 39. While warm-air heating is performed, the deodorization or sterilization or both thereof indoors can be very conveniently performed. Even if the filters are clogged with refuse or dirt, air is supplied through the air flow clearances, and air flow quantity is not reduced nor stopped. Hot air is supplied as usual, and since there is no possibility that the apparatus body is burned out by heat, the apparatus can be used with ease. Since there is no need for a user to clean the filters frequently, the apparatus can be very conveniently used. COPYRIGHT: (C)2005,JPO&NCIPI
