The fixed plate 541 is connected to the third elevating bar 465 provided in the second cam unit 46, and the lifting operation, the washing brush 542 is the number of bins to wash each bin formed on the front of the plate It is provided in the number corresponding to.

And since the number of dishes is different for each plate, the lower cleaning unit 54 is detachable so that it can be replaced with a lower cleaning unit 54 provided with a corresponding number of cleaning brushes 542 according to the number of dishes. It is preferable to install.

Therefore, the present invention can easily wash the plate of various specifications by easily replacing the lower washing unit that is detachably formed according to the number of bins of the plate to be washed.

As shown in FIG. 9, the transfer unit 543 may include a driving pulley 544 installed below the lower spline 523 of the vertical shaft 521, and a plurality of driven pulleys installed on the rotation shafts of the respective cleaning brushes 542. 545 and a belt 546 connecting the drive pulley 544 and the plurality of driven pulleys 545 at one time.

Next, the operation of the plate washing apparatus for avalanche according to a preferred embodiment of the present invention.

When the power switch, not shown, is operated, the motor 30 is driven by being supplied with power, and the driving part 41 of the transfer means 40 is driven using the rotational power of the motor 30.

At this time, the food plate is inserted into the initial position (P1) of the dish washing apparatus 10 in an upside down state so that the upper surface is directed downward.

When the plate is inserted into the initial position P1 as described above, the rotary arm 412 and the link arm 413 rotate while the rotary shaft 411 of the driving unit 41 rotates, so that the first and second rack gears 414 and 415 are rotated. Reciprocate linearly.

At the same time, while the first cam shaft 451 of the first cam unit 45 rotates, the first cam 452 moves the transfer module 44 up and down.

Thus, the first and second transfer arms 421 and 431 coupled to the first and second rack gears 414 and 415 are moved up and down by the first cam 452 to elliptically move the plate in the first position at the initial position P1. Transfer it to the standby position P3 via the washing position P2.

Then, the first washing unit 51 washes the lower surface of the food plate transferred through the first washing position (P2).

In this case, the water storage unit 24 and the detergent storage unit 25 supplies the water and the detergent stored therein to the first washing unit 51.

The plate washed as described above is transported to the standby position P3 along the transport direction by the first lever 422 of the first transport arm 421.

The plate fed to the standby position P3 is transferred to the second washing position P4 along the transfer direction by the second lever 4321 of the second transfer arm 431.

At this time, while the sensing bar 234 installed on the transport path between the standby position (P3) and the second washing position (P4) is rotated by the plate, the rotating bar 235 of the sensing unit 232 is shown in Figure 3b It rotates along the direction of the arrow.

Then, as the rotary bar 235 is separated from the coupling groove 482 of the clutch unit 48, the connecting pin 484 is the second rotary gear 47 by the elastic force of the spring 485, as shown in FIG. It is inserted into the connecting groove 472 of the.

Accordingly, the second cam shaft 461 receives the rotational power of the motor 30 to rotate the second cam 462 to be convex downward, and the third cam 463 to be convex upward.

That is, as the second cam 462 is convex downward, the second elevating bar 464 coupled to the second cam 462 moves upward to move the upper cleaning unit 53 upward. As the cam 463 becomes convex upward, the third elevating bar 465 coupled to the third cam 463 moves downward to move the lower washing unit 43 downward.

Therefore, the upper washing unit 53 and the lower washing unit 54 may move in a direction away from each other to form a space in which the plate is transferred can be easily transferred to the second washing position (P4).

Subsequently, as shown in FIG. 6, the second cam 462 rotates convexly upward, and the third cam 463 rotates convex downwardly so that the upper cleaning unit 53 and the lower cleaning unit 54 are rotated. It is moved in a direction that comes closer to each other.

At this time, when the plate is seated in the second washing position (P4), by the restoring force of the first spring 237 coupled to the rotating bar 235, the sensing bar 234 returns to the original position, the rotating bar 235 Is coupled to the coupling groove 482 of the clutch unit 48, the connecting pin 484 moves into the installation groove 483 while elastically deforming the second spring 485.

Therefore, as the connection between the clutch unit 48 and the second rotary gear 47 is released and the rotation of the second cam shaft 461 is stopped, the second cam 462 and the third cam 463 detect the next plate. It maintains its current position until it rotates 234.

In this state, the cleaning brushes 532 and 542 of the upper and lower cleaning units 53 and 54 wash second and upper surfaces of the plate.

That is, the present invention can extend the product life of the washing unit by protecting the operator by lifting the upper and lower washing units by rotating the second cam shaft depending on whether the plate is transported.

At this time, the water storage unit 24 and the detergent storage unit 25 supplies the water and detergent stored therein to the second washing unit 52.

As described above, while the second washing operation is performed, the second transfer arm 431 of the transfer means 40 discharges the plate in which the second washing operation is completed by the elliptical movement of the second rack gear 415 (P5). Transfer it to) and discharge it to the outside.

Such transfer and cleaning operations are carried out sequentially sequentially, and accordingly, the present invention can quickly and cleanly wash a large number of plates.

Through the process as described above, the present invention can automatically clean the plate by performing the second dish washing operation before the washing revolution while automatically transferring the plate using the transfer means.
