Further, when the operation switch 35 is pressed, the water draining operation shown in FIG. 3 is performed. Hereinafter, the draining operation will be described with reference to FIG.

When the operation switch 35 is pressed, the control circuit 36 determines that the switching valve 20 is closed if the micro switch 33 is OFF (1) according to the ON / OFF state of the micro switch 33, and activates the alarm device 37. When the micro switch 33 is ON, it is determined that the switching valve 20 is open, and the solenoid valve 32 is opened for a certain period of time (3).
Drain the water.

When the operation lever 5 is operated and the micro switch 33 is turned on during the sound output in the step (2) (4), the sound output is stopped and the process goes to the step (3) to open the solenoid valve 32 for a certain time. When it is detected that the predetermined time has elapsed from the start of step (3), the solenoid valve 32 is returned to the closed state.

Thereafter, a sound is output from the alarm device 37 (5) to notify the end of the first draining operation, and to return the operating lever 5 to urge the closing of the switching valve 20. The driving lever 5
Is operated and the micro switch 33 is turned off (6),
The sound output is stopped and the solenoid valves 29 and 30 are opened for a certain period of time (7) to drain the branch washing water pipe 24. When the second draining operation is completed in this way, the alarm device 37 outputs a sound for a certain period of time (8), and notifies the end of the operation to end a series of operations.

Therefore, the worker can use the water supply hose 8 in the collar 19.
Then, when the operation lever 5 is moved down to the operation side and the operation switch 35 is pressed in the cleaning state, the solenoid valve 32 is opened for a predetermined time and compressed air is introduced into the cleaning water pipe 15. The introduced compressed air is closed by the check valve 23 on the water supply side of the washing water pipe 15, so that it is sent to the sprinkling pipes 16 to 18 and the washing water remaining in the pipe is discharged.

If the operator forgets to switch the operation lever 5 to the operation side and presses the operation switch 25, a sound is output from the alarm device 37 to notify that the operation lever 5 is to be switched to the operation side. , The drainage of the pipeline can be performed as it is.

When the first drainage is completed in this way, there is a voice output notifying the end. If the operation lever 5 is returned to the stop position in accordance therewith, the solenoid valves 29 and 32 are opened for a certain period of time and the branch cleaning line 24 is opened. The remaining washing water is discharged from the nozzle 25.
After the completion of the second drainage, a sound is output for a certain period of time, so the operator may confirm this and finish the work.

In the above operation, the draining of the washing water pipe 15 and the draining of the branch washing water pipe 24 are performed separately, but this is because the pipe resistance of each of the pipes and the sprinkling pipes 16 to 18 and the nozzle 25 communicating with each other is reduced. This is because, even if compressed air is simultaneously introduced into both pipelines 15 and 24, there is a disadvantage that the air flow is uneven and complete drainage cannot be performed or a long time is required until drainage occurs.

The washing water before and after the check valve 23, which is not drained in this draining operation, is opened when the solenoid valve 32 is closed with the end of the operation, the normally open check valve 23 is opened, and the washing water pipe 15 is opened to the atmosphere. , So it is discharged naturally from the collar 17.

The present invention is not limited to the above embodiment, and various embodiments can be considered. For example, it is also possible to adopt a configuration in which the switching valve 20 can be automatically opened and closed in place of an electromagnetic valve, and a temperature sensor is provided to detect the temperature, and when the temperature drops, water is automatically drained at the end of each cleaning operation. .

[Effects of the Invention] The invention is configured as described above, and the compressed air used for ashtray washing can drain the washing water pipe and the branch washing water pipe, thus requiring additional equipment such as a heater. It is possible to reliably prevent freezing without performing. As a result, both the washing water pipe and the air pipe can be used by branching, so that the water supply pipe and the air pipe are simply connected to the main body of the washer in the same manner as in the conventional mat washer with the ashtray washing function. Thus, an inexpensive and easy-to-use device can be obtained without increasing the number of connection pipes to the main body. In addition, the drainage of the washing water pipe and the branch washing water pipe is performed alternately, and the air is concentrated in one pipe without being dispersed in both pipes. Can be reliably discharged by high-pressure air.
