<P>PROBLEM TO BE SOLVED: To provide a hot-air heating system having a convection fan filter designed to be easy to attach and detach. <P>SOLUTION: The convection fan filter 17 to be detachably attached to a convection fan guard 16 provided to cover an air suction port formed on a back face plate 3 of a device body 1 is disposed to have a substantially L-shaped cross section by a filter upper part 19 with a grip part 18 formed in substantially the center and a ventilation part 21 with a plurality of ventilation holes 20. An upper part engaging member 27 with a magnet is provided at the upper inside of the ventilation part. A portion positioned below the upper part engaging member 27 protrudes toward an inner face side at the ventilation part 21 to form a projecting part. When the convection fan filter 17 is attached, first, the projecting part 29 comes in contact with an upper face portion of the convection fan guard 16, to move the upper part engaging member 27 to a position at the front of the convection fan guard 16, thereby allowing easy attachment of the convection fan filter 17. <P>COPYRIGHT: (C)2013,JPO&INPIT |
