As shown in FIGS. 3 and 4 , the jet nozzle 40 is installed on the first side plate 22 of the washing tank 20 and receives the washing water (W) pumped by the circulation pump 80 from the opposite side. It blows strongly toward the 3 side plate 25 side.

The jet nozzle 40 is, inside the water level of the washing water W, strictly speaking, as shown in FIGS. 3, 4, 5 and 6, the first side plate 22 at the lower half of the washing water W. a plurality of first jet nozzles 41 installed in the 42) is arranged in a zigzag shape as a whole. As these first and second jet nozzles 41 and 42 are disposed on the first side plate 22 in a zigzag shape, the washing water ejected with a strong pressure from the first and second jet nozzles 41 and 42 is transferred to the third side plate. (24) forms a large vortex in the entire area inside the washing water (W) while moving to the side. The vortex generated at this time acts as a separation force when the pre-washing dishes are stacked on top of each other, and separates the food waste attached to the dishes.

Here, since the first and second ejection nozzles 41 and 42 are directly installed on the first side plate 22, the first and second ejection nozzles 41 and 42 are can increase or decrease the number of For example, when a large vortex needs to be formed in order to separate the dishes that are to be washed preliminarily because they are easily stacked, the number of the first and second ejection nozzles 41 and 42 can be increased.

In addition, after a consumer purchases the dishwasher of the present invention, if a large vortex is to be formed for a specific purpose, a hole in the first side plate 22 may be drilled and installed separately, and accordingly, the first and second The number of ejection nozzles 41 and 42 can be increased.

As shown in FIG. 3 , the distribution pipe 50 is connected to a hose 51 connected to the plurality of first and second jet nozzles 41 and 42 . The distribution pipe 50 distributes the washing water pumped by the circulation pump 80 to the first and second jet nozzles 41 and 42 at an even pressure.

The filtering part 70 is for filtering food waste contained in the washing water (W) drained to the washing tub drain pipe 60). It consists of a recessed stepped drain groove 71 communicating with the drain pipe 60 and a sieve 72 detachably covered in the stepped drain groove 71 .

The sieve 72 is attached to and detached from the stepped drain groove 71, and a plurality of small sized sieve holes 72a are formed to filter food debris contained in the washing water drained to the washing tub drain pipe 60.

As shown in FIG. 3 , the circulation pump 80 is installed between the washing tub drain pipe 60 and the distribution pipe 50 and pressurizes the washing water drained into the washing tub drain pipe 60 to the distribution pipe 50 . Accordingly, by circulating and reusing the washing water used for primary washing, a large amount of tableware can be primary washed using a minimum amount of water.

The washing water supply pipe 90, as shown in FIG. 3, connects the water pipe (not shown) and the distribution pipe 50, and by operating the first valve 91, clean water (washing water) supplied from the water pipe. It is supplied to the distribution pipe (50). In this case, the first valve 91 is preferably a solenoid valve that operates when power is applied.

The drain drain pipe 100, as shown in FIG. 3, connects the sewage pipe (not shown) and the washing tank drain pipe 60, and by operating the second valve 102, the washing water used for primary washing is drained into the sewage pipe. do. The drain drain pipe 100 drains into the sewer pipe when the washing water is excessively contaminated in the preliminary washing process.

As shown in FIG. 2 , the air discharge pipe 110 is disposed in a zigzag shape on the bottom plate 21 of the washing tank 20 to discharge air to form air bubbles. The air discharge pipe 110 generates air bubbles in the washing water W by spraying the air supplied from the air pump 112 through the air hole 111 while primary washing is in progress.

The air bubbles generated by the air discharge pipe 110 apply an impact to the food wastes firmly attached to the dishes so that the food wastes are separated. Separate food waste. That is, since the air bubble is delivered in all directions through the washing water W, even if the dishes are overlapped or closely adhered, they are transmitted through the gap between the dishes to enable primary washing.

The perforated plate 120 is sandwiched from the upper side of the washing tub 20 to cover the air discharge pipe 110 , as shown in FIG. 5 . A plurality of perforated holes 121 are formed in the perforated plate 120 . Accordingly, air discharged from the air discharge pipe 110 is transferred to the washing water W through the perforated hole 121 to form an air bubble. The perforated plate 120 prevents small dishes or cutlery from being pinched between the air discharge pipe 110 and the washing tub bottom plate 21 in the preliminary washing process.

For reference, small-sized tableware such as spoons and forks move a lot in the washing water W by vortex and air bubbles in the primary washing process, and in this process, between the air discharge pipe 110 and the bottom plate 21 . is often caught in In this case, the operator must remove the spoon or fork sandwiched between the air discharge pipe 110 and the bottom plate 21 by putting his hand into the dirty and invisible washing water W, and in this process a lot of time and effort It takes this, and the primary cleaning efficiency is lowered.

However, in the present invention, by employing the perforated plate 120, it is possible to fundamentally prevent small-sized tableware from being pinched between the air discharge pipe 120 and the bottom plate 21, thereby enabling efficient ever-cleaning. it can be done

As shown in FIG. 3 , the vortex guide plate 130 is installed while forming an oblique slope at the corner between the third side plate 24 and the bottom plate 21 opposite the ejection nozzle 40 . In (40), when the washing water is discharged at a high pressure, a swirling water flow is formed inside the washing water (W) accommodated in the washing tank (20). By forming a vortex that largely rotates from the bottom plate 21 to the upper surface of the washing water according to the vortex guide plate (according to the vortex guide plate), numerous dishes are prevented from overlapping each other in the preliminary washing process.

The washing receiving light irradiation unit 140 irradiates light with the washing water (W) while the primary washing is in progress. As shown in FIGS. 2 and 3 , the washing receiving light irradiator 140 is a transparent tube that is sealed and coupled to the groove 141 formed in the horizontal direction in the vortex guide plate 130 installed at an oblique inclination angle. 141 and a lamp 142 installed inside the light-transmitting tube 142 .

The washing water light irradiation unit 140 obliquely irradiates light to the upper side of the washing water W, and the operator determines the degree of contamination of the washing water W by the amount of light passing through the washing water W, or the amount of food debris contained in the washing water. It is possible to determine whether to replace the washing water or not.
