Description

{Tray Cleaning Apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plate cleaning apparatus, and more particularly, to a plate cleaning apparatus which applies a plate laminate in which a plurality of plates are stacked in a plate washing tank to collectively clean each plate.

In schools where food is served, such as schools, public institutions, units, and resting places, a large number of plates are used. These plates are fed into a plate washing machine after they have been eaten and then washed, Or food waste.

At this time, it is difficult to remove the rice grains and some residual residues which are heavily clogged on the plate, and the remnants remain even after passing through the dishwasher.

Therefore, in the related art, food waste is firstly removed through an avalanche cleaning step including a dipping process and an avalanche cleaning process before a plate is introduced into a plate washing machine, and then the food waste is introduced into a dishwasher to perform washing, rinsing, and drying do.

In this avalanche cleaning process, a tableware with food residue is placed in a water tank in which cleaning water containing detergent is stored, the food residue is called, the operator grasps the brush with one hand and holds the plate with the other hand. And the upper and lower sides of the dishwasher were wiped alternately to remove the food residue attached to the dishes.

However, in the above-described method, it is possible to thoroughly clean dishes of dozens of units. However, when a dish with hundreds or more dishes is cleaned repeatedly, a large amount of crowd was applied to the shoulder or limbs of the operator by repeated cleaning operation, This can cause back pain or muscle aches, thus avoiding work.

On the other hand, in the Korean Patent Registration No. 10-1612389, the ultrasonic wave is generated so that microvibration can be given using the cleaning liquid in the water tank as a medium, so that the contaminants adhering to the tableware are removed by cavitation due to microvibration In addition, Korean Patent Registration No. 10-1288221 proposes a dishwashing apparatus using an ultrasonic wave. In the airbag type avalanche cleaner, a plate is provided on an upper plate inclination angle guide and a lower plate separating guide in a boiling tank, The automatic separation operation of sloping from 65 degrees to 75 degrees in the inward direction and the continuous laminating operation are performed and the detergent and the hot water are desorbed in the crude tank and the air having passed through the air drop generator and the air drop pipe is discharged to the bottom Air bubbles are generated by several air bubble generating nozzles installed in The washing water is circulated, it has proposed a called air bubble trays avalanche avalanche cleaner operation and the cleaning operation is automatically configured to be fulfilled in the trays.

Such a dish washing apparatuses are preferably used in a water tank, and a large amount of plates are put into a water tank to collectively clean the dishes in terms of efficiency of operation.

However, it is difficult to stably remove food waste adhering to the plate through the ultrasonic waves or air bubbles. In addition, since foreign substances remaining on the surface of the plate are removed by simply oscillating ultrasonic waves or dispersing air bubbles in a single water tank, The dishwashing of the plate is performed by the washing water contaminated by a large amount of foreign matter and contamination of the dishwashing plate by the foreign substances contained in the washing water may be caused.
