As described above, while the washing water and the rinsing water of the washing water storage tank 130 and the rinsing water storage tank 140 are supplied to the washing nozzle 161 and the rinsing nozzle 162 through the distribution container 160, the washing water is stored in the washing water storage tank ( 130, the washing water reuse structure of the dishwasher 10 of the present invention having a structure in which the water in the distribution container 160 is supplied to the sink 200 through the discharge pipe 163 efficiently recycles hot water and detergent. While reducing resources and costs required for dish washing under the following, this feature will be described in more detail with reference to the operation state of the dishwasher 10.

First, in the state where the hot water of the water supply unit 150 is filled with a predetermined level to the water level detection sensor not shown in the washing water storage tank 130 and the rinsing water storage tank 140 through the water supply pipe 151, on the cradle 120 Mounting the dish 121 to be washed in the cover 110 and after the cover 110, using the operation button (not shown) to operate the dishwasher 10, the washing water pump pump 131 is first operated at the same time detergent supply pump The washing water in the state in which the detergent is mixed with the hot water is pumped into the distribution container 160 through the washing water supply pipe 132 to maintain a predetermined pressure, and the washing water is supplied to the washing nozzle 161 by the pressure. By being supplied and sprayed on the tableware 121, the tableware 121 is washed.

The washing water sprayed through the washing nozzle 161 as described above is dropped to the bottom after washing the dishes 121, the washing water is re-collected back into the washing water storage tank 130 through the mesh cover 137, washing water Recirculated to the distribution container 160 by the pump pump 131, through this, even if no separate hot water is supplied from the water supply unit 150 by using the washing water to recirculate significantly reduced the amount of hot water, washing water storage tank The washing water exceeding the proper water level in 130 is discharged through the drain pipe 136, and various foreign substances are filtered through the mesh cover 137 to prevent the water from flowing into the washing water storage tank 130 to clean the washing water storage tank 130. I can keep it.

In addition, the wash water pumping pump 131 preferentially pumps only the contaminated washing water under the wash water storage tank 130 through the side by the guide plate 131 ′ in the wash water storage tank 130, thereby preventing the washing water pumping pump 131. Prevents malfunction and pressure drop, ensuring stable and accurate injection and circulation of wash water.

After washing the dish 121 by performing the washing operation several times for a predetermined time while spraying the washing water, the washing water pump 131 is stopped and the rinsing pump pump 141 is operated, and at the same time, the rinse supply pump 145. ) Is rinsed in the state in which the rinse is mixed with hot water is pumped into the distribution container 160 in the rinsing water supply pipe 142 to maintain a predetermined pressure, the rinsing water is supplied to the rinse nozzle 162 by this pressure When the rinsing time is completed, the rinse of the dish 121 is sprayed onto the dish 121, and when the rinsing time is completed, the rinse supply pump 145 is stopped, and the rinsing operation is performed again only with clean hot water without rinsing to complete the washing of the dish 121. do.

During the washing and rinsing operations, when the sink 121 is used for cleaning, such as washing the dishes 121, cleaning the first floor, or cleaning the floor, the auxiliary water supply 164 is opened to the pressure in the distribution container 160. By using the supplied washing water or rinsing water to the discharge pipe 163, it is possible to perform various operations in the sink 200 without using a separate water supply tank 210 connected from the outside to save hot water, so the discharge pipe The hot water recovered through 163 is contaminated washing water under the washing water storage tank 130, so that the clean washing water may be maintained into the washing water storage tank 130 in which the contaminated washing water is drained.

In addition, when the hot water is filled into the sink 200 by the auxiliary water supply tank 164, by stepping on the opening and closing valve 221 it can be performed easily and accurately in a short time, such as the operation of drainage and level control of the hot water in the sink 200 Therefore, the work such as the washing of the tableware 121, the initial cleaning, or the cleaning water such as the floor can be performed more efficiently.

And when the hot water in the washing water storage tank 130 or the rinsing water storage tank 140 is insufficient to fall below a predetermined water level through the distribution container 160, the water level detection sensor detects this through the water supply unit 150 It is desirable to operate automatically to continuously fill the water level so that the wash water and the rinsing water are continuously supplied.

Although the above has been illustrated and described with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment, anyone of ordinary skill in the art to which the present invention belongs, variously modified and implemented in various ways Of course, such changes are intended to fall within the scope of the claims set forth.
