PURPOSE:To prevent contaminated waste air from scattering and to automatically remove stains by loading a pull-out member capable of being pulled in or out of a front wall within a frame body, fitting an elastic member on the upper surface of a side wall of the pull-out member and the upper surface of a diaphragm, and press-connecting the elastic member onto the lower side of the bottom surface of the heating system main body, and providing a louver on the front wall of the pull-out member. CONSTITUTION:The flow of waste air entering into a pull-out member 17 is discharged to the outside of a louver 22. When the pull-out member 17 is inserted into a frame member 15, an elastic member mounted on a frame side wall 23 and an elastic member 28 mounted on the upper surface of a diaphragm 26 are press-connected to the lower side of the bottom surface 10 of the heating system main body 2. For this reason, a stained air flow in not scattered and discharged in a direction of other than the louver 22. When the pull-out member 17 is pulled out from the frame member 15, since the elastic member 28 is press-connected to the lower surface of the discharge port 11 of the bottom surface 10 of the apparatus main body 2, stains such as oil, water drops or the like are removed by the elastic member 28, and they drop in the pull-out member 17. Stained matters collected within the pull-out member 17 are cleaned by taking out the pull-out member.
