A cleaning tank 20 having a discharge hole 21 formed therein and having a bottom discharge hole 22 through which food waste generated in the avalanche cleaning process and the washing water W are discharged; An air discharge tube (30) which is submerged in washing water (W) contained in the washing tank (20) and has a plurality of air holes (30a) through which air is discharged; An air pump (40) installed inside the case (10) and supplying air to the air discharge pipe (30); A washing water spray nozzle 50 installed on one side wall of the washing tank 20 for spraying high pressure washing water W onto the surface of the washing water W; A washing water collection tank 60 for collecting washing water W overflowed into the sidewall discharge hole 21 and washing water W having passed through the bottom discharge hole 22; A pressure feeding pump 70 for feeding the washing water W recovered in the washing water collection tank 60 to the washing water spray nozzle 50; A filtering unit 80 for filtering the food waste from the washing water W discharged to the bottom discharge hole 22; And a warning signal generating unit (90) for generating a signal to process the food waste when the food waste collected in the filtering unit (80) becomes more than an acceptable amount. The grinding unit 100 may be provided at the bottom of the washing water collection tank 60 for grinding and discharging food waste.

The case 10 has a space in which the air pump 40, the washing water collecting tub 60 and the pressure feeding pump 70 are installed and the faucet 15 for supplying clean washing water to the upper side Respectively.

A sidewall discharge hole (21) is formed in the upper part of the inner side wall of the washing tank (20). The pipe 21a connected to the sidewall discharge hole 21 is connected to the inside of the washing water collection tank 60. When the washing water W is filled up to the side wall discharge hole 21 in the washing tank 20, the washing water is discharged to the washing water collection tank 60 through the side wall discharge hole 21, Prevent overflow.

A bottom discharge hole 22 is formed at the bottom of the washing tank 20 and a pipe 22a connected to the bottom discharge hole 22 is connected to the inside of the washing water collection tank 60. Accordingly, the washing water (W) discharged to the bottom discharge hole (22) is recovered in the washing water collection tank (60).

A first valve (23) for selectively opening and closing the bottom discharge hole (22) is provided at a lower portion of the bottom discharge hole (22). The first valve 23 closes the bottom discharge hole 22 when it is desired to separate the filtering section 80 to be described later from the washing water collection tank 60 or to urge the food waste attached to the tableware for a long time, do. The first valve 23 can be manually operated by an administrator or automatically operated by electricity.

On the upper side of the air discharge pipe (30), a supporting net (24) for supporting a plurality of dishes is fixed. The support net 24 prevents the dishes from coming into direct contact with the air discharge pipe 30 or being caught between the air discharge pipe 30 and the bottom of the washing tub.

On the other hand, a plurality of supporting bars (not shown) for raising dishes may be formed on the supporting net 24, in which case the dishes can be installed on the supporting net 24.

On the bottom of the washing tank 20, a washing tank hopper surface 25 inclined toward the bottom discharge hole 22 may be formed as shown in FIG. The washing tub hopper surface 25 guides the food waste contained in the washing water W to the bottom discharge hole 22 so that the food waste can be effectively discharged to the bottom discharge hole 22.

The air discharge tube 30 generates air bubbles by supplying air supplied from the air pump 40 to the washing water W through the air holes 30a. The air bubbles impact the food waste on the tableware to effectively separate the food waste, and also penetrate into the embedded tableware to separate the food waste attached to the inner surface of the tableware.

At this time, since the air bubbles are transferred through the washing water W, even if the dishes are stacked, they can be transferred to the inside of the dishes.

The washing water spray nozzle 50 is installed at one side of the side wall of the washing tank 20 so that the washing water which is pushed by the pressure feeding pump 70 is strongly sprayed onto the surface of the washing water W stored in the washing tank 20. The high-pressure sprayed washing water W forms a vortex so as to separate food garbage attached to the tableware and to separate the superimposed tableware from each other. The air bubbles sprayed from the air discharge pipe 30 are uniformly transferred to the inside and the outside of the dishes So that food waste can be separated in three dimensions. One or more of the wash water spray nozzles 50 may be provided depending on the capacity of the wash tank.

As described above, since the washing water spray nozzle 50 installed at one side of the side wall of the washing tank 20 and spraying the washing water at high pressure toward the washing water surface is used, the washing can be performed even if various types and large amount of utensils are inserted at random.

The washing water overflowed by the sidewall discharge hole 21 and the drain water W drained through the bottom discharge hole 22 are recovered. The recovered washing water W is supplied to the washing tub 20 through the pressure feeding pump 70 and the washing water spray nozzle 50 to allow the avalanche washing to proceed.

A recovery tank drain pipe 61 for draining wash water W is provided at the bottom of the wash water recovery tank 60 and a second valve for selectively opening and closing the recovery tank drain pipe 61 is provided in the recovery tank drain pipe 61 62 are installed. When the washing water W is excessively contaminated in the repeated avalanche washing process, the second valve 62 drains the contaminated washing water W by opening the recovery tank drain pipe 61.

On the other hand, a stepped sub-recovery tank 63 may be formed on the bottom 60a of the wash water collection tank 60, as shown in FIG. Since the sub-collecting tank 63 is stepped from the bottom 60a, if the food waste is once received, the vortex is not raised to the upper side even if the vortex is generated in the circulation process of the washing water, and the food waste is circulated together .

At the bottom of the sub-collecting tank 63, an inclined turning means hopper surface 64 is formed and the collecting tank draining pipe 61 can be installed at the lower end of the turning means hopper surface 64. In this case, the food waste can be effectively discharged when the recovery means hopper surface 64 guides the food waste to the recovery tank drain pipe 61, thereby opening the recovery tank drain pipe 61.

The pressurization pump 70 pressurizes the wash water W recovered in the wash water collection tank 60 to the wash water spray nozzle 50. The pressure pump (70) is provided with a sub-crushing part (75) for finely crushing the foreign substances contained in the incoming washing water.

In the process of the washing water being recovered into the washing water collection tank 60, the food wastes contained in the washing water are filtered by the filtering unit 80, but the washing water still contains a large amount of foreign matter as small food waste. Such foreign matter gradually accumulates on the inner wall of the pipe connecting the pressure feeding pump 70 and the washing tub 20, and thus the washing water collecting ability by the pressure feeding pump 70 is lowered over time.

In order to prevent foreign matter from accumulating on the inner wall of the pipe connecting the pressure feeding pump 70 and the washing tub 20, the pressure feeding pump 70 is provided with a sub-crushing unit 75 for finely crushing foreign matter will be. Foreign materials contained in the washing water introduced by the sub-crushing unit 75 are finely crushed, foreign substances can be prevented from accumulating on the inner wall of the pipe while the washing water W is being fed to the washing tank 20, It is possible to prevent deterioration of the washing water collection ability even if the time passes.

The filtering unit 80 is for filtering the food waste from the washing water W discharged to the bottom discharge hole 22 and is formed with a number of holes through which the washing water W can pass and the food waste can be caught.

On the other hand, when the food waste filtered by the filtering unit 80 is filled, the filtered food waste should be treated. To this end, the filtering section 80 includes a mesh 81a having a container shape as a whole and a mesh 81 having a pair of guide blades 81b formed at the upper end of the mesh container 81a; And a pair of guide supporting ends 82 provided on the inner upper side of the washing water collecting tank 60 and slidably supporting a pair of guide vanes 81b toward the door 11 side. 1, when the door 11 is opened, the manager can handle the food wastes by taking out the water supply wastes 81, and conversely, the clean water supply wastes 81 can be supplied to the guide support ends 82 It can be inserted by mounting.

The warning signal generating unit 90 generates a signal to process the food waste when the food waste accumulated in the filtering net 81 of the filtering unit 80 becomes equal to or greater than the acceptable amount. The warning signal generating unit includes: A light irradiating unit 91 provided on one side of the inside of the washing water collecting tank 60 and irradiating light to the upper side of the screening net 81 and a light irradiating unit 91 provided on the other side of the washing water collecting bath 60, And a light receiving section 92 for receiving light. Thus, when the food waste is filled in the sieve net 81 so as to protrude to the upper side of the sieve net 81, the light irradiated from the light irradiating unit 91 is blocked by the food garbage and is not received by the light receiving unit 92, In this case, the warning signal generator 90 generates a warning signal to process the food waste.

The crushing unit 100 is installed on the bottom of the washing water collection tank 60 to crush and discharge the food waste. When the grinding unit 100 is employed, a separate effort to empty the washing water collection tank 60 can be omitted.

The dishwasher washing device having the above-described structure minimizes the amount of the washing water W consumed by collecting and reusing the washing water W generated in the course of washing a plurality of dishes in the washing tub 20 There is.

By generating the air bubbles and the high-pressure washing water W by the air discharge pipe 30 and the washing water spray nozzle 50, it is possible to perform the avalanche washing with any type of dishes, and even the auger washing can be performed . Therefore, the user can easily use the washing tub 20 because the washing tub 20 needs to be charged with various types of time.

Since the washing water W is recovered in the washing water collection tank 60 and then circulated to the washing tank 20, the washing water consumed in the avalanche washing process can be minimized.

In addition, it is possible to perform the avalanche cleaning even when any type of tableware or tableware is superimposed. Accordingly, the user can make the avalanche cleaning only by inputting various types of timing into the cleaning tank 20, thereby maximizing the convenience.

And, like the conventional avalanche washing machine, it is possible to eliminate the management burden of frequent replacement of the brush by not using the brush.
