Abstract

PURPOSE:To freely select the inserting direction of an air filter according to the setting location by a method wherein a filter inserting port and a pair of guide frames are provided to allow putting the air filter into them from top or from slantly above in the front, and the pair of the guide frames has tapered parts to make the air filter tilt forward. CONSTITUTION:The dimension of depth L1 of a filter inserting port 16 and the dimension of lower clearances L2 between frame members 22 and 23 of guide frames 17 and 18 are more than 2 - 3 times as large as the dimension of thickness L of the lower part of an air filter 21, and the upper clearances L2' between the frame members of the guide frames 17 and 18 are larger than the lower ones. The frame members 22 of the guide frames 17 and 18 have sloped parts 22A so as to allow the air filter 21 inserted into the filter insertion port 16 to tilt forward. This constitution allows freely selecting the insertion direction of the air filter 21 in a wide range from top to slightly above in the front. Moreover, the air filter inserted into the guide frames 17 and 18 tilts forward along the sloped parts 22A and is stably attached on around an air suction port 2.

C) Problems to be Solved by the Invention However, in the above-mentioned hot air heater, the direction in which the air filter can be installed and removed is restricted to a narrow range diagonally to the front, which not only makes it impossible to insert and remove the air filter from above, but also makes it difficult to insert and remove the air filter. The mouth was narrow and it took some time to put it in and take it out. In addition, arc-shaped air filters have problems with precision when molded with resin, and because they are made using wire mesh, they have the disadvantage of being expensive and prone to chattering noise.
