PURPOSE:To make it possible to change a structure comprising an inner cooling exhaust system only to that of a an external forced exhaust system easily by providing a detachable plate to cover the bottom of an exhaust passage provided in a main body. CONSTITUTION:An exhaust passage 15 for exhausting air after cooling is formed in a main body 10, and the bottom of the exhaust passage 15 is covered with a detachable plate 16. This makes the exhaust air emitted inside a room, so if it is inconvenient, that is, when the temperature in the room is increased because the exhaust air takes the heat inside the main body to be hot, for example, the detachable plate 16 can be removed, and an exhaust duct connected with an external fan can be connected at the part instead, so exhaust heat from the inside the unit can be forcedly discharged to the external, thereby a temperature rise in the room can be prevented. |
