Description

Prime washer {PRIMARY DISHWASHER}

The present invention relates to a rough washing machine, and more particularly, it has a structure in which the washing water accommodated in the washing tank circulates to form a circulating vortex to wash dishes and at the same time filter out foreign substances remaining in the washing water in the process of circulating the washing water. It relates to a prime washer that can prevent re-contamination of old dishes.

A large number of tableware is used in places where group meals are served, such as schools, public institutions, military units, and rest areas, and these tableware are put into the priming washing machine at once after the meal is finished, placed on a conveyor, an automatic transport device, and sprayed with a nozzle. Through the washing and disinfection process by passing through the washing water, the leftovers and food residues on the tableware are removed.

At this time, there was a problem in that it was difficult to remove the rice grains or some leftover residues that were heavily clumped on the tableware.

Therefore, before putting the dishes into the primary washing machine, the food residues are first removed through a primary washing step including a soaking process and primary washing, and then put into the primary washing machine to perform washing, rinsing, and drying processes.

In this preliminary washing process, after soaking the food residues by putting the dishes with food residues in the washing water mixed with detergent into the water tank, the operator holds the brush with one hand and the tableware with the other hand. It has been done in the order of wiping the dishes alternately to separate food residues attached to the tableware. In the case of washing a large amount of tableware as it is essential that the worker repeatedly washes the dishes with a brush in the process of the primary washing process, There was a problem in that the worker was subjected to a strain and caused muscle pain such as arthritis.

In order to solve this problem, Korean Patent No. 10-1612389 uses the cleaning liquid in the water tank as a medium to generate ultrasonic waves so that micro-vibrations can be provided, so that contaminants attached to dishes are removed due to cavitation caused by micro-vibrations. was proposed, and in Korean Patent No. 10-1288221, in the air bubble plate priming washer, the plate was placed on the upper plate inclination angle guide and the lower plate separation guide in the soaking tank in the longitudinal and inner direction 65 Automatic separation operation and continuous filling operation are carried out with an inclination of 75 degrees from the figure, detergent and hot water are added to the soaking tank, and the air that has passed through the bubble generator and bubble pipe is installed in the lower part of the plate separation guide block. It is changed to the form of air bubbles by the droplet generating nozzle and the washing water is circulated. At this time, we propose an air bubble table pre-cleaner configured to automatically perform soaking and pre-cleaning of the plate.

However, there was a limitation in removing food residues from the food adhering to the tableware through ultrasonic waves or air bubbles in the water tank. There was still a problem in that foreign substances remaining on the washing water were re-covered on the dishes.

It is installed in the steam supply port 10 so that

In particular, the steam spray nozzle 400 is installed in connection with the steam supply unit 10 disposed in a space separated from the space in which the washing water of the washing tank body 100 is received and the steam pipe as a medium, and the rear end of the steam pipe. A steam supply pipe 410 connected and in communication with the steam supply pipe 410 is rotatably connected to and installed along the outer peripheral surface of the rear end of the steam supply pipe 410 through a bearing, and the rear end of the steam supply pipe 410 is horizontally provided. It consists of a steam injection pipe 420 having a front end disposed at an angle and a rear end disposed at an inclination from the front end and horizontally with the rear end of the steam supply pipe 410 .

That is, the steam supply pipe 410 and the steam injection pipe 420 provide a path through which the steam generated from the steam supply unit 10 moves, and in this case, the steam supply pipe 410 is disposed in a fixed state, , as the steam injection pipe 420 is rotatably connected and installed through a bearing along the outer peripheral surface of the rear end of the steam supply pipe 410, the pressure of the steam moving through the steam supply pipe 410 is transmitted and interlocked. so it will rotate.

Accordingly, the steam spray nozzle 410 can spray steam to a wide area in the space in which the washing water of the washing tank body 100 is accommodated, as well as the entire area of the washing object for the washing object accommodated in the space containing the washing water. Steam can be sprayed over.

In addition, if the rear end of the steam injection pipe 410 is formed so as not to be horizontal when steam is sprayed into the space in which the washing water of the washing tub body 100 is accommodated, the washing water of the washing tub body 100 is accommodated in the space. The rear end of the steam injection pipe 420, which is rotatably provided to solve a problem such as steam being sprayed upward from the space in which the washing water of the washing tank body 100 is accommodated by the sprayed steam pressure, is part of the steam supply pipe 410 ) and arranged horizontally with the rear end of
