Description

Soak type washing apparatus having improved water stream structure

The present invention relates to a immersion washing apparatus having an improved water flow formation structure, and more particularly, by forming a water flow in the immersion washing tank, the water flow is evenly formed on the surface of each plate immersed in an upright state in the immersion washing space, It relates to a immersion washing apparatus having an improved water flow forming structure that enables stable water flow immersion washing of plates.

Schools, public institutions, military units, and rest areas, where group meals are served, use a large amount of plate. or food debris.

At this time, it is difficult to remove the rice grains or some leftover residues that are heavily agglomerated on the plate, so that residues remain even after going through the dishwasher.

Therefore, in the art, before putting the plate into the plate washer, the food wastes are first removed through a preliminary washing step, and then put into the plate washer to perform washing, rinsing, and drying processes.

This pre-cleaning is performed by placing a plate with food residues in a large container with detergent dissolved in it and soaking the food residues. Then, while the cleaner holds the brush with one hand and the plate with the other hand, the brush alternately sweeps the upper and lower surfaces of the plate with the brush. It has been carried out by wiping and separating food residues adhering to the plate.

However, in the above method, it is possible to pre-wash several tens of plates, but when pre-washing more than several hundred plates, a lot of strain was applied to the shoulders or limbs of the washers due to repeated washing operations, and eventually arthritis, etc. or muscle pain.

On the other hand, in relation to the present invention, in Korean Patent Registration Publication No. 10-1612389, the cleaning solution in the water tank is used as a medium to generate ultrasonic waves so that micro vibrations can be given, so that contaminants adhering to the dishes are removed by cavitation caused by micro vibrations. A dish washing device using an ultrasonic wave is proposed, and in Korean Patent Registration No. 10-1288221, in the air bubble dish priming washer, the dish plate is placed on the upper plate inclination angle guide and the lower plate separation guide in the soaking tank in the longitudinal direction. Automatic separation operation and continuous filling operation are performed to incline from 65° to 75° in the inner direction, detergent and hot water are added to the soaking tank, and the air that has passed through the bubble generator and bubble pipe is removed from the lower part of the guide block for separating the plate. It is proposed that the air bubble plate primary washer is configured to change into an air bubble shape by several air bubble generating nozzles installed in the kiln and the washing water is circulated.

These plate pre-cleaning devices are preferable in terms of efficiency of work because they put a large amount of plate in the water tank to pre-wash in batches.

However, it is difficult to stably remove the food debris adhering to the plate through the ultrasonic waves or air bubbles, and simply oscillating ultrasonic waves or dispersing air bubbles in a single water tank removes foreign substances remaining on the surface of the plate, Pre-washing of the plate is made by washing water contaminated with a large amount of foreign substances, and the contamination of the plate being pre-washed by foreign substances contained in the washing water may be caused.

In particular, since a thick oil film layer is formed on the surface of the washing water, the oil film layer is buried on the surface of the plate and causes contamination of the plate surface in the process of taking the plate after preliminary washing out of the water tank.

The immersion washing device 1 includes a immersion washing tank 10 having a immersion space 10a in which the plates T are upright and immersed as shown in FIGS. 1 and 3; The washing water stored in the immersion space 10a is sucked through the recovery pipe 22 and recovered, and then supplied through the water supply pipe 23, and the washing water stored in the immersion space 10a is circulated inside the circulation pump unit 20 ); and one or more vertical jet heads disposed on the bottom of the immersion washing tank 10 and vertically upwardly discharging washing water supplied through the water supply pipe 23 of the circulation pump unit 20 into the immersion space 10a ( 30) is included.

The immersion washing tank 10 is composed of a housing having an open immersion space 10a at the top, and a support guide 11 for supporting the plates T to be spaced apart from the floor at a set height is disposed on the bottom, the The plates (T) maintain a state spaced apart from the bottom of the immersion space (10a) at a set height through the support guide (11).

In this embodiment, by arranging one or more vertical jetting head parts 30 in the immersion cleaning tank 10, the surface of each plate T arranged upright in the immersion space 10a of the immersion cleaning bath 10. By spraying high-pressure washing water in the vertical direction to form a water flow that circulates in the vertical direction in the immersion space (10a), it promotes even preliminary cleaning of each plate (T) arranged upright in the immersion space (10a).

In this embodiment, a total of five of the vertical spray head parts 30 are spaced apart from the bottom of the immersion space 10a, and a plate (T) spaced apart from the bottom of the immersion space 10a through the support guide 11 ) to promote stable immersion cleaning.

The vertical injection head unit 30 proposed in this embodiment includes a hollow chamber 31 communicating with the water supply pipe 23 of the circulation pump unit 20 as shown in FIGS. 2 to 5; It is formed by cutting the upper part of the chamber 31 in the longitudinal direction and includes an incision-type vertical nozzle port 32 for vertically upwardly spraying the washing water supplied into the chamber 31 .

The chamber 31 of the vertical injection head part 30 according to this embodiment is manufactured in a shape in which the cross-sectional area gradually increases from the upper part where the vertical nozzle port 32 is formed to the lower part, and through the circulation pump part 30 The washing water supplied into the chamfer 31 is vertically sprayed along the vertical nozzle opening 32 having a narrower cross section so that the vertical injection pressure is increased.

In particular, on the side wall of the immersion space 10a, a side drain 12, which is a drainage path of the washing water discharged upward from the bottom of the immersion space 10a to wash the surface of the plate T, is formed, and in the washing process of the plate The circulation pump unit 20 recovers the washing water that is drained along the side drain 12 through the recovery pipe 22 and collected in the filtration water collecting tank 24, and through the water supply pipe 23, each vertical jet head unit 30 to be watered in

At this time, the side drain 12 is formed at a height of at least 2 or more with respect to the total height value 3 of the plate T arranged upright in the immersion space 10a, as shown in FIG. 3, so that the vertical injection head part ( The washing water vertically discharged through 30) is discharged upward to a sufficient height, and then is sucked into the circulation pump unit 20 along the side drain 12 formed on the side of the immersion space 10a.

In particular, in this embodiment, as shown in Figs. 4 and 5, in the chamber 31, one end of the elastic opening/closing sheet 33 has a fixed end fixed to the inner wall of the chamber 31 and the other end has a free end. Arrange left and right symmetrically.

Therefore, the interval between the elastic opening and closing sheets 33 is elastically adjusted according to the injection pressure of the washing water supplied into the chamber 31 and sprayed along the vertical nozzle opening 32 , and through this, the vertical nozzle opening 32 is The open area is flexibly controlled.

That is, when the amount of water supplied to the washing water in the chamber 31 by the circulation pump 21 constituting the circulation pump unit 20 decreases, the other end of the elastic opening/closing sheet 33 forming the free end approaches each other and the vertical nozzle The opening area of the sphere 32 is reduced, and at this time, the washing water is vertically sprayed through the vertical nozzle opening 32 having a narrow opening area.

On the contrary, when the amount of water supplied in the chamber 31 by the circulation pump 21 constituting the circulation pump unit 20 increases, the other end of the elastic opening/closing sheet 33 forming the free end is vertical while being spaced apart from each other. The open area of the nozzle opening 32 is increased, and at this time, the washing water is vertically sprayed into the immersion space 10a with a thicker thickness.

Thus, the control unit changes the driving amount of the circulation pump 21 constituting the circulation pump unit 20 according to the set period to adjust the flow rate of the washing water supplied to the vertical injection head unit 30, thereby immersing the immersion space 10a. It is possible to promote more even washing of the plates (T) by forming various types of vertical water flow within.
