The air supply to 38 and 40 is cut off by turning off the solenoid valve 36.

Next, the operation of the cleaning device configured as described above will be explained. It is now assumed that all the devices installed in the washing machine main body 1 are in a state before starting washing, as shown in FIG. That is, the door cylinder 30
The piston rod 30a of the lifting cylinder 9, the piston rod 9a of the lifting cylinder 9, and the piston rod 18a of the sealing cylinder 18 are each shortened, the door 29 and the lifting unit 5 are located at the upper end, the object loading port 28 is open, and the lid 15 is shortened. shall be in the open position.

Therefore, the operator first places the object to be cleaned in the basket 7 of the lifting unit 5, and then presses a start button (not shown).The piston rod 30a of the door cylinder 30 extends, lowers the door 29, and loads the object to be cleaned. Close mouth 28. Loading port for items to be cleaned 28
When the door 29 is closed, the sealing cylinder 18 is activated and the piston rod 1 of the sealing cylinder 18 is closed.
8a, the lid 15 opens into the drain outlet 14.
It rotates to the side to seal the drain outlet 14.

When the drain outlet 14 is sealed with the lid 15,
The cleaning pump 32 operates, and the cleaning liquid in the suction tank 31 sucked up from the cleaning liquid tank 27 is sent to the four-way switching valve 33 .
Depping cleaning tank 2 of cleaning chamber 2 from port P ₀ of
Cleaning liquid is supplied to 1. In this case, the cleaning pump 32 continues to supply the cleaning liquid. As a result, the cleaning liquid overflows from the sink 23 formed in the cleaning chamber 2, and as shown by the imaginary line in FIG.
2 will always be satisfied. Sink spout 2
The cleaning liquid overflowing from 3 flows through the fluid path 24 and the drain path 25.
Then, it is filtered through the round cage strainer 26 and returned to the washing tank 27 again.

When the depositing cleaning tank 21 is filled with the cleaning liquid 22, the lifting cylinder 9 is activated, and the piston rod 9a of the lifting cylinder 9 starts to extend and retract. As the piston rod 9a of the lifting cylinder 9 expands and contracts, the lifting unit 5 moves up and down in the AA' direction along the pair of guide rails 3, 3. Therefore, the object to be cleaned placed on the lifting unit 5 comes to move up and down in the cleaning liquid 22 stored in the depping cleaning tank 21, thereby resulting in depping cleaning, that is, the cleaning of the object to be cleaned. The entire surface is cleaned. This depping cleaning is performed for a predetermined period of time.

When such depping cleaning is completed, the sealing cylinder 18 is operated again, and this time the piston rod 18a of the sealing cylinder 18 is shortened to open the lid 15, and the dirty liquid after the depping cleaning is discharged from the drain outlet. 14, is filtered by a round basket strainer 26 through a drainage channel 25, and sent to a cleaning liquid tank 27. On the other hand, when the lid 15 is opened,
The four-way switching valve 33 is switched to port _P1 .
Therefore, the cleaning liquid in the suction tank 31 is
The cleaning liquid is supplied to the fixed cleaning slit nozzles 12 and 13 through the port P ₁ of the four-way switching valve 33, and is injected from the fixed cleaning slit nozzles 12 and 13 toward the object to be cleaned, thereby performing so-called jet cleaning. Chips and the like that have not been removed by cleaning, that is, chips and the like that have adhered to tap holes, drilled holes, etc. of the object to be cleaned, are removed.

Thereafter, the four-way switching valve 33 is sequentially switched to ports P ₂ and P ₃ in the same manner as described above, and jet cleaning is performed by sequentially jetting cleaning liquid from the fixed cleaning slit nozzles 10 and 11. Here, by sequentially switching the four-way switching valve 33, the fixed cleaning slit nozzles 10, 11,
The cleaning liquid is jetted out sequentially from the fixed cleaning slit nozzles 10, 11, 12, and 13 to perform jet cleaning. May be set.

Therefore, the fixed cleaning slit nozzle 10,
11, 12, and 13, the operation of the cleaning pump 32 is stopped and the solenoid valve 35 is switched on to blow air out from the fixed air blow nozzles 37 and 39 to spray the target after cleaning. The washed items are dried. Next, the solenoid valve 35 is turned off and the solenoid valve 36 is turned on, thereby turning the fixed air blow nozzles 38 and 4 on.
The object to be cleaned is subsequently dried by blowing out air from zero.

Fixed air blow nozzles 37, 39 and 3
When the drying of the object to be washed by the cleaning objects 8 and 40 is completed, the operation of the lifting cylinder 9 is stopped, and the piston rod 9a of the lifting cylinder 9 is shortened, so that the lifting unit 5 is stopped at the original position. When the lifting unit 5 stops at the original position, the door cylinder 30 is activated and the piston rod 30a of the door cylinder 30 is shortened, so that the door 29 rises and opens the object loading port 28. Finally, one cleaning cycle ends when the operator takes out the object to be cleaned.

Depending on the object to be cleaned, jet cleaning may be followed by depping cleaning.

(Effects of the Invention) As explained above, according to the present invention, while moving the object up and down, the object to be cleaned is subjected to depping cleaning by the depping cleaning tank and jet cleaning by the cleaning nozzle, and at the same time Since drying can be carried out in one cleaning chamber, even if the objects to be cleaned have different shapes and dimensions, the objects to be cleaned can be reliably cleaned without having to make special setup changes each time. In addition, the dirty liquid after cleaning is discharged outside the cleaning chamber each time, and the cleaning liquid is replaced every time cleaning is performed, so cleaning can always be performed with a clean cleaning liquid, and the cleaning effect can be improved compared to the conventional example.

Furthermore, since the depping cleaning, jet cleaning, and drying operations can be performed continuously in one cleaning chamber, the cleaning machine body can be downsized, and the installation space and manufacturing costs can be reduced.
