Further, the interlocking means 30 is pivotally supported on the upper support member 26 by the upper connection pivot 31 and is supported by the lower support member 27 by the lower connection pivot 32, so that the upper support member 26 and the lower support member 27 are interlocked with each other. The door 24 and the lower door 25 are configured to open and close in conjunction with each other.
[0021]
The cleaning tank 22 is provided with a stopper portion 33, which is configured to maintain the open state of the door body (the upper door body 24 and the lower door body 25) by contacting the lower support member 27.
[0022]
The lower door body 25 is provided with a push button switch 34 and a locking means 35 for holding the lower door body 25 in a closed state. The lock means 35 is configured to be released. The openings of the upper door body 24, the lower door body 25, and the cleaning tank 22 are sealed by a sealing member (not shown) formed of an elastic body.
[0023]
The first holding portion 37 provided in the interlocking means 30 and the second holding portion 38 provided in the cleaning tank 22 are connected by a first spring 39 (tension coil spring) constituting an automatic opening mechanism, and the door body is opened. It is urged to open automatically.
[0024]
Further, the sliding member 40 is pivotally supported so as to be in contact with a part of the upper support member 26 in the cleaning tank 22, and the second holding member 41 provided on the sliding member 40 has a second spring ( A tension coil spring) 42 is attached, and the sliding member 40 applies a load to the contact portion 43 with the upper support member 26 in a direction to close the door body.
