The present invention does not wash the washing tank by shaking up, down, left and right in a state in which a plurality of plates are overlapped, but by periodically hitting and pressing the outermost side of a plurality of plates to periodically increase or decrease the spacing between a plurality of plates overlapping each other. The present invention relates to a plate washing apparatus capable of efficiently removing food debris, etc. on the surface of the plate as the interfacial tension generated between the plates due to the tension is released and the washing water flows between the plates at the same time.

In general, in places where group meals are provided, such as schools, military, luncheons and rest areas, hereinafter referred to as "group catering"), a distribution-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 subjected to a separate washing operation for reuse.

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

When washing the plates manually, not only requires a lot of labor, but also it is cumbersome and time-consuming, and there are problems such as washing the plates not being properly cleaned. In order to release the table, a washing machine for washing plates that can automatically and hygienically wash a 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 Jul. 27, 2012) has a main body, fixedly arranged inside the main body, and a plurality of plate supports protruding at equal intervals. A plate support frame and a plurality of plate boards are coupled to enable repeated left and right movement by a driving means in a state located inside the main body, and located corresponding to the plate support frame of the plate support frame, but facing each other The earth is arranged protruding at equal intervals, and a plate movement induction frame for inducing left and right movement for a plurality of plates accommodated in the body, and a plate support frame and plate movement induction frame having the plate support in the vertical direction. A plurality of injection ports are disposed on the outer peripheral surface to eject washing water and rinsing water toward the plate arranged to be accommodated, and it comprises a rotary nozzle of a pipe structure coupled to rotate in the vertical direction based on the horizontal line by a power means. Disclosed is an automatic dishwasher.

In addition, Korean 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 unit, 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 filtration tank A circulation pump unit for circulating the 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, Disclosed is a plate immersion type primal cleaning device that is spaced apart and configured including 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 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 on 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 for diffusing the washing water supplied through the water supply pipe in the lower part of the soaking tank, and forming a primary cleaning space for arranging the plates upright in the upper part of the diffusion space, and fixed to the soaking tank Equal pressure cleaning structure comprising one or more vibrating motors that vibrates the immersion tank by generating vibrations through transmission Disclosed is a immersion-type primary cleaning device for a plate having.

In the case of the above-mentioned conventional plate washing apparatus, the washing tank (soaking 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 generated between the plates is generated 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 molecules of the liquid. 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 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, which is the interfacial tension.

Therefore, in the case of the 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, it is being used as a preliminary washing device rather than an actual plate washing device.
