When the drainage tank 23 is attached in this state, the arm 29 of the float 26
Corresponds to the mounting prevention means 32. Already float part 2
6 is supported by the support portion 25, so that the drainage tank 23
Can no longer move to the rear surface 5b side of the main body 1, and the drainage tank 23 is prevented from being mounted at a predetermined position.

This allows the user to recognize that the drainage tank 23 is not in a normal state, to prevent the user from operating in this state, and to prompt the user to attach the cover 30 to the drainage tank 23. it can.

When the drain tank 23 is mounted after the water in the drain tank 23 has been discarded, the drain tank 23
Is guided by the guide rib 33 and is mounted. At this time, as shown in FIG. 6, when the cover 30 is not sufficiently mounted on the front side of the drainage tank 23, the front side 5a of the drainage tank 23 is pressed by the guide rib 33 and
0 is attached. This can prevent the dew water from leaking out of the drain tank 23 when the dew water is drawn out in a state where the dew water has accumulated in the drain tank 23.

In the above embodiment, the drainage tank 23
Is detachable from the front surface 5a of the main body 1, but the present invention is not limited to this, and the drain tank 23 may be detachable from another surface of the main body 1.

Although the shaft 27 of the float 26 is pivotally supported by the drain tank 23, the float 26 may be pivotally supported by a shaft provided in the drain tank 23.
