PURPOSE:To improve the safety, by decreasing the temperature of air to be discharged to the outside by mixing high-temperature air discharged from a heating chamber with low-temperature air having cooled electrical parts in front of an outlet, and decreasing the temperature before discharge. CONSTITUTION:Hot air (a) in a heating chamber 6 flows out through discharge ports 12 into a discharge duct 8, a portion a1 of which is directly discharged to the outside of the equipment through an outlet 3; while the rest a2 thereof flows out into a space 15 between the upper wall of an equipment body 1 and the upper wall of the heating chamber 6, mixes with air a3 which has cooled electrical parts, and flows out through the outlet 3. By this arrangement, the temperature of discharged air is lowered and the safety can be improved.
