PURPOSE:To prevent water from being overflown by deactuating a float switch when a drain tank is filled with water, when an apparatus body falls down, and when the drain tank is not set at a predetermined position on the apparatus body. CONSTITUTION:Once a drain tank 15 is filled with water, a float lever 51A is pushed upward owing to buoyancy force of a float 51. For this, a switch lever 52a is released, and a switch lever 52a falls down to bring a float switch 49 into a non-operation state. Once an apparatus body falls down, it floats from a floor surface, so that an aseismatic lever 52 is engaged downward by a spring 53 to a lower portion than a bottom place 3. Accordingly, a push bottom part of the float switch 49 is brought into a recessed configuration with respect to the switch lever 52a, and hereby the float switch 49a is deactivated. Further, when the drain tank 15 is not set at a predetermined position on the apparatus body, the float switch 49 is not operated as a matter of course. Hereby, any trouble such as water overflow can be prevented. |
