Abstract
A dish washer including a sump unit disposed below a wash tub and configured to collect water, and an upper nozzle, a lower nozzle, and a subsidiary nozzle configured to spray water received from the sump unit onto dishes/cutlery contained in at least one rack. The sump unit includes a circulating pump configured to pump water collected in the sump unit, and a distributing element configured to allow water pumped by the circulating pump to be sprayed through any one of the lower nozzle and the subsidiary nozzle, and to be sprayed selectively through the upper nozzle. Accordingly, it is possible to independently perform an intensive wash mode of spraying water only through the subsidiary nozzle.
Claims9
A dish washer comprising:
- a wash tub forming a wash chamber;
- at least one rack arranged in the wash chamber;
- a lower nozzle disposed below the at least one rack;
- an upper nozzle disposed above the at least one rack;
- a subsidiary nozzle configured to spray water at a higher pressure than a pressure of the lower nozzle and a pressure of the upper nozzle towards a predetermined area of the at least one rack;
- a sump unit disposed below the wash tub and configured to collect water, the sump unit including a lower port to discharge water that is to be transferred to the lower nozzle, an upper port to discharge water that is to be transferred to the upper nozzle, and a subsidiary port to discharge water that is to be transferred to the subsidiary nozzle;
- a circulating pump disposed in the sump unit and configured to pump water collected in the sump unit;
- and
- a distributing element disposed in the sump unit configured to distribute water pumped by the circulating pump to any one of the lower nozzle, the upper nozzle and the subsidiary nozzle, the distributing element comprising a rotatably installed distributing plate fabricated in the shape of a circular plate and having a communicating hole that extends in a circumferential direction to correspond to both the upper port and any one of the lower port and the subsidiary port.
A dish washer comprising:
- a wash tub forming a wash chamber;
- a rack to hold dishes arranged in the wash chamber;
- a lower nozzle disposed below the rack to spray water upwards towards the rack;
- an upper nozzle disposed above the rack to spray water downwards towards the rack;
- a subsidiary nozzle disposed below the rack and to one side of the rack to spray water upwards towards the one side of the rack, the subsidiary nozzle being configured to spray water at a higher pressure than a pressure of the lower nozzle and a pressure of the upper nozzle;
- a circulating pump to pump water to the lower nozzle, the upper nozzle and the subsidiary nozzle;
- and
- a distributing element to distribute water pumped by the circulating pump to any one of the lower nozzle, the upper nozzle and the subsidiary nozzle, the distributing element comprising a rotatably installed distributing plate fabricated in the shape of a circular plate and having a communicating hole that extends in a circumferential direction to correspond to both an upper port leading to the upper nozzle and any one of a lower port leading to the lower nozzle and a subsidiary port leading to the subsidiary port.
