BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate cleaning apparatus having an improved cleaning structure, and more particularly, to a plate cleaning apparatus having an improved cleaning structure for stably rinsing a plate by stably rubbing between a brush and a plate during rinsing, ≪ / RTI >

In recent years, large-scale personnel such as schools, military bases, and public institutions have been actively providing group meals, and this trend is expected to expand gradually.

Normally, in the above-mentioned group feeding, since rice, soup, and various side dishes are received in each cupboard of the plate, they are transported and consumed, and therefore hygienic management of such plate is very important.

However, it is very cumbersome to manually clean the plates every time, and in the case of group meal caterers who repeatedly wash large quantities of plates, they also complain of musculoskeletal pain.

Accordingly, in recent years, there has been developed a washing process for washing a plate and a plate washing device for automatically performing a rinsing process, thereby ensuring convenience in washing the plate.

However, in the conventional plate washing apparatus, the plate is passed through the washing rollers rotating in the transverse direction, so that the limitation of preventing the brush of the washing roller from reaching the relatively deep bowl is generated. Accordingly, And this phenomenon is further intensified in a military plate with a deep depth of a cup.

Unless the stable cleaning of the cup is carried out in the washing process, the inner wall of the cup is inevitably adhered to a stain such as a scale. In order to remove it, a chemical is used in the field to periodically remove stains such as scales However, this is not desirable from the viewpoints of the human body and the environment.

Therefore, even if the dishwasher is cleaned through the dishwasher, it is pointed out that oil or foreign matter remains at the corners of the dishwasher for a long period of time and a stable hygienic condition can not be secured.

Thus, in the field of the art, there is a demand for a plate cleaning apparatus having a new type of cleaning structure capable of stably cleaning the surface of the plate through the plate surface and the even friction.

The primary pumping section P1 is provided with a primary collection tank 13 ' The washing / rinsing water recovered in the primary collection tank 13 'is injected again through the injection nozzles 12a disposed in the rinsing section 12 and collected into the secondary collection tank 13.

The tertiary pumping section P3 discharges the cleaning / rinsing water collected in the secondary collection tank 13 to the cleaning section 11 at a high pressure through the spray nozzle 11a formed in the cleaning section 11 , And the washed / rinsed water collected in the discharge tank is discharged to the outside so as to save the number of rinsing / rinsing by rinsing and rinsing.

In the present invention, in implementing the plate washing apparatus 1, the washing section 30 having the improved cleaning structure is disposed in the washing section 11 and the rinsing section 12, To be stably washed and rinsed by the transfer portion 20 in the lateral direction.

As shown in FIGS. 3 to 5, the washing tool 30 for washing and rinsing the plate is basically composed of one or more brushes 32 having washing washers 32a formed on one side thereof, And is reciprocating forward and backward.

The washing section 30 is symmetrically arranged on both inner walls of the washing section 11 and the rinsing section 12 so that the washing section 11 and the rinsing section 12 are horizontally So that the two-sided cleaning of the plate T passing in the direction of the arrow T is achieved.

The cleaning tool 30 according to the present embodiment includes a fixing bracket 31; A lifting bracket 34 installed on the fixing bracket 31 in a retracted manner; A brush (32) fixed to the lifting bracket (34) and having cleaning wicks (32a) formed on one side thereof; And a retracting member 33 installed on the fixing bracket 31 so as to move forward and backward by providing a conveying force to the lifting bracket 34 to which the brush 32 is fixed.

According to the present embodiment, the cleaning bristles 32a formed on one surface of the brush 32 are generally made of a plastic wire material, a metal wire material or the like having excellent flexibility and abrasion resistance.

4 and 5, the brush 32 is reciprocated in the longitudinal direction by the driving of the advancing / retreating member 33, and the surface of the plate T transported laterally by the transporting unit 20 Is repeatedly rubbed through the washing bristles (32a), thereby stably cleaning and rinsing the plate (T).

Here, the advancing / retreating member 33 for moving the brush 32 forward and backward may be a cylinder, a rack, a pinion type, or the like that converts the forward and reverse rotational forces of the electric motor into linear feed forces to make the brush travel forward and backward .

However, in the present invention, the electric motor 33a for generating a rotational force, the rotary shaft 33d for rotating in one direction by the driving of the electric motor 33a, And a link member 33b for connecting the rotary shaft 33d and the rotary shaft 33d in an eccentric link structure. So that the brush 32 with the cleaning bristles 32a in close contact with the surface of the cleaning brush 32 reciprocates forward and backward to thereby perform stable cleaning and rinsing of the plate T.

4, when the rotary shaft 33d rotates in one direction by the driving of the electric motor 33a, the lifting bracket 34 connected to the rotary shaft 33d via the link member 33b in an eccentric link structure is fixed to the fixed bracket 34. [ The lifting bracket 34 is provided with a guide slot 34a in the lateral direction to compensate the left and right eccentricity of the link member 33b, Brushes can also be composed of monoliths.
