Description

Rotating cleaning water spray device {ROTATING TYPE CLEANING WATER SPRAYING APPARATUS}

The present invention relates to a washing water spraying device installed inside a dishwasher and spraying washing water on food plates. More specifically, it relates to a first washing water spraying unit equipped with two first nozzles and a second washing water spraying unit equipped with two second nozzles. 2 This relates to a rotary washing water spraying device that allows the food tray, especially the corners of the food tray, to be cleaned cleanly as the washing water spray unit is simultaneously rotated by an electric chain.

In general, the plates used for group meals in schools, cafeterias, rest areas, etc. have a large amount of food residue on them even when the leftovers are roughly disposed of after the meal.

Therefore, in order to remove food residue from the plate, a plate washer is used that sprays washing water and at the same time uses brushes to wash the food residue remaining on the plate.

As an example of such a food plate washer, Korean Patent Registration No. 10-1129371 (2012.03.26.) includes a main body having an inlet on one side through which the food plate enters and an outlet on the other side through which the plate is discharged; a conveyor for transporting the food tray from the entrance to the outlet of the main body; It includes a plurality of plate separation axes rotatably installed on both sides of the conveyor, and separation guides each spirally wound and fixed to an outer peripheral surface of the plate separation shaft, and when each of the plate separation axes rotates, each of the separation guides opens. a plate separation supply unit that inserts the side of the lowest layer plate placed on the separation guide into the gap so that it is separated from the plates stacked on the separation guide and supplied to the conveyor; a plate level detection unit for detecting the horizontal state of the plate supplied from the plate separation supply unit and placed on the conveyor; and a washing unit including a plurality of brushes installed between an inlet and an outlet of the main body to clean the food plates transported by the conveyor.

In addition, Korean Patent Registration No. 10-1575151 (2015.12.07.) includes a housing that forms the exterior; A food plate input unit installed on one side of the housing and including a support unit for supporting the stacked food plates and a plurality of spiral cams disposed opposite each other to separate the stacked food plates one by one and move them from the stacking position to the washing position; a plate cleaning unit installed inside the housing to clean the food plates one by one; a plate discharge unit that discharges the plate washed in the plate washing unit; a food plate transfer unit that transfers the food plate from the food plate input unit, through the food plate cleaning unit, to the food plate discharge unit; It is installed between the bottom of the blade of the spiral cam and the upper surface of the food plate input unit, so that when the food plate is caught by one of the plurality of spiral cams, the irradiated light is blocked by the food plate, An optical sensor that generates a jamming signal accordingly; and a plate washer installed at a rear end of the plate discharge unit to collect the food plates coming out of the plate discharge unit.

This plate washer is equipped with a separate washing water spray device that sprays washing water onto the plate.

As an example of such a washing water spray device, Korean Patent Publication No. 10-2013-0110725 (October 10, 2013) states that washing water contained in a water tank is transferred to a supply pipe by a pump, and the washing water is transmitted through nozzles of a spray pipe coupled to the supply pipe. In a dishwasher in which food plates are cleaned by being sprayed, and food plates are washed while being transported by a chain rotating between driving and driven sprockets, brackets are fixed to the frames respectively mounted on the upper and lower sides of one side of the spray pipe. Brushes are combined with the upper and lower brackets installed opposite each other to sweep and clean the top and bottom of the food tray entering the washing water spray device along the chain, and brackets are installed on the frames mounted on the upper and lower sides of the other side of the spray pipe, respectively. A plate washing device for a dishwasher is disclosed, wherein brushes are respectively coupled to upper and lower brackets that are fixed and installed opposite each other to wipe the top and bottom of a washed plate with a spray of washing water.

However, in the case of the conventional washing water spray device as described above, since the nozzle through which the washing water is sprayed is fixedly installed, the washing efficiency for the food plate is reduced, and in particular, there is a problem in that the corners of the rectangular food plate are not properly cleaned.
