Description

Dish washing device having improved section transfer structure

The present invention relates to a dish washing apparatus having an improved section transfer structure, and more particularly, to the sequential transfer and section transfer of the dishes impregnated in the washing water while impregnating the dishes to be washed and sequentially moving sections in the longitudinal direction. It relates to a dish washing apparatus having an improved section transfer structure that promotes soaking and washing of dishes in the process.

A large amount of tableware is used in places where group meals are served, such as schools, public institutions, military units, and rest areas. These tableware are put into the dishwasher and washed in batches after the meal is served. or food debris.

At this time, it is difficult to remove the rice grains or some leftovers that are heavily clumped on the tableware, so that residues remain even after going through the dishwasher.

Therefore, in the art, before putting the dishes into the dishwasher, the food wastes are first removed through a preliminary washing step, and then put into the dishwasher to perform washing, rinsing, and drying processes.

In this preliminary washing, the dishware with food debris is placed in a large container with detergent dissolved in it, soaked in the food debris, and then the cleaner holds the brush with one hand and the dishware with the other hand, then wipes the upper and lower sides of the dish with the brush alternately. It has been carried out by separating food residues attached to the tableware.

However, in the above method, it is possible to pre-wash tens of units of dishes, but when pre-washing more than several hundred dishes, a lot of strain was applied to the shoulders or limbs of the washers due to repeated washing operations, and eventually arthritis, etc. or muscle pain.

On the other hand, in relation to the present invention, Korean Patent Registration Publication No. 10-1612389 uses the washing liquid in the water tank as a medium to generate ultrasonic waves so that micro vibrations can be imparted to remove contaminants attached to the dishes due to cavitation caused by micro vibrations. A dish washing device using ultrasonic waves is proposed.

In addition, in Korean Patent Registration No. 10-1288221, in the air bubble dish washing machine, the dish is tilted from 65 degrees to 75 degrees in the longitudinal and inner directions on the upper dish inclination angle guide and the lower dish separation guide in the soaking tank. Automatic separation operation and continuous filling operation are performed, detergent and hot water are added to the soaking tank, and the air that has passed through the bubble generator and the bubble pipe is released into the air by several air bubble generating nozzles installed at the bottom of the tableware separation guide block. It changes to a bubble shape and the washing water circulates, and at this time, we propose an air bubble tableware primary washing machine configured to automatically perform soaking and primary washing of dishes.

These tableware pre-cleaning devices are preferable in terms of work efficiency, since a large amount of tableware is put into the water tank and pre-washed in batches.

However, it is difficult to stably remove food debris adhering to the tableware through the ultrasonic waves or air bubbles, and simply oscillating ultrasonic waves or dispersing air bubbles in a single water tank removes foreign substances remaining on the surface of the tableware, Pre-washing of the tableware is performed by the washing water contaminated with a large amount of foreign substances, which may cause contamination of the tableware being pre-washed by the foreign substances contained in the washing water.
