In general, in places where group meals are served, such as schools, military, cafeterias and service areas, etc. (hereinafter referred to as "group cafeteria"), a ration-type plate that can hold rice, soup, and various side dishes at once is mainly used. After these plates are used in large quantities at one time, they are recovered and separately washed for reuse.

However, even when the leftovers are emptied after serving and meals, a large amount of food residues are on the surface of the plate, making it difficult to clean.

When washing the plates manually, not only requires a lot of labor, but it is cumbersome and time-consuming, and there are problems such as washing the plates not being properly cleaned. In order to release the dishwashing device, a washing machine for washing plates that can automatically and hygienically wash a large number of plates is mainly used.

As an example of such a plate washing device, Korean Patent Laid-Open No. 10-2012-0083950 (published on July 27, 2012) has a main body, fixedly arranged inside the main body, and a plurality of plate support units protruding at equal intervals.

In addition, Republic of Korea Patent Registration No. 10-1791213 (published on October 30, 2017) has a soaking tank for immersing the plate upright, and a filtering tank for filtering and discharging the washing water drained from the soaking tank, which is formed by dividing the left and right by an upright water level plate. A water tank, one or more jet pipes disposed at the bottom of the soaking tank and having jet holes for jetting washing water, and collecting the washing water drained from the filtration tank and supplying it to a jet pipe disposed on the bottom surface of the soaking tank, immersion with the filter tank A circulation pump unit for circulating washing water between the tanks, a filtering unit disposed in the filtration tank to filter the washing water flowing in from the soaking tank to filter food contaminants contained in the washing water, and the jetting pipe on the bottom surface of the soaking tank Disclosed is a plate immersion-type pre-cleaning apparatus configured to be spaced apart and configured to include a vibrating screen unit having a vibrating screen in which a plurality of through holes are formed.

In addition, Republic of Korea Patent Registration No. 10-1831140 (published on February 22, 2018) discloses a water tank in which a soaking tank and a filtration tank are partitioned on the left and right by an upright water level control plate, and disposed at the bottom of the soaking tank to recover the washing water drained from the filter tank A circulation pump unit for discharging and supplying washing water upwardly into the soaking tank through one or more water supply pipes disposed at the bottom of the soaking tank after recovery through the tube, and spaced apart from the bottom surface of the soaking tank in the soaking tank, the interior of the soaking tank A perforated screen for forming a diffusion space in the lower part of the soaking tank to diffuse the cleaning water supplied through the water supply pipe, and a primary cleaning space for arranging the plates upright in the upper part of the diffusion space, and fixed to the soaking tank A pressure equalization cleaning structure comprising one or more vibrating motors that vibrates the immersion tank by generating vibrations through electricity Disclosed is a immersion-type primary cleaning device for a plate having.

In the case of the conventional plate washing apparatus described above, it has a structure in which a washing tank (dipping tank) is shaken up and down, left and right, up and down, left and right, in a state in which a plurality of plates are overlapped, so that the food residues on the surface of the plate are washed.

However, when a plurality of plates of the same shape are submerged in the washing tank while overlapping each other, interfacial tension is generated between the plates due to the surface tension of water.

The interfacial tension refers to the force acting in the direction of decreasing the area at the interface where different components are in contact with each other. For example, a liquid tends to be spherical in order to reduce its surface area. This phenomenon is due to the attraction between the liquid molecules. Molecules inside the liquid are completely surrounded by surrounding molecules and receive uniform attraction from all directions, whereas molecules at the interface are surrounded by only the other side. You will receive a manpower directed towards you. Therefore, the number of molecules at the interface decreases and the interfacial area tries to contract, so the liquid has a kind of tension along the interface. This tension is the interfacial tension.

Therefore, in the case of a conventional plate washing device, even if the washing tank (dipping tank) is shaken up, down, left, and right in a state where a plurality of plates of the same shape are overlapped with each other, water does not flow properly between the plates due to the aforementioned interfacial tension. As the washing effect is reduced due to the friction of water, there is a problem that it cannot be used as an actual plate washing device.
