Abstract

A washing operation and a drying operation are performed while a basket which is located inside a washing tub and accommodates dishes reciprocates in a vertical direction of a washing tub due to a driving device. The basket reciprocates in order to pass through an injection nozzle which injects washing water and an air nozzle which injects air to perform the washing operation while passing through the injection nozzle and to perform the drying operation while passing through the air nozzle. Through this, a small amount of dishes may be washed and dried in a short time and the dishes may be washed using a small amount of water and energy.

First claim

What is claimed is:

1 . A dishwasher comprising:
a body; a washing tub provided inside the body of the dishwasher; a basket configured to accommodate a dish; a basket driver configured to reciprocate the basket in the washing tub; an injection nozzle configured to spray washing water toward the basket; and an air nozzle configured to blow air toward the basket.

2 . The dishwasher of claim 1 , wherein the injection nozzle comprises a plurality of injection nozzle arms including injection holes through which the washing water is sprayed, in which a pair of the plurality of injection nozzle arms is disposed at a predetermined interval to be parallel to each other such that the injection holes face each other, and
wherein the basket reciprocates between the pair of the plurality of injection nozzle arms.

3 . The dishwasher of claim 1 , wherein the air nozzle comprises a plurality of air injection nozzle arms including air injection holes through which the air is blown, in which a pair of the plurality of air injection nozzle arms is disposed at a predetermined interval to be parallel to each other such that the injection holes face each other, and
wherein the basket reciprocates between the pair of the plurality of air injection nozzle arms.

4 . The dishwasher of claim 2 , wherein the driving device is provided between the pair of the plurality of injection nozzle arms and the pair of the plurality of air injection nozzle arms, and is configured to be elongated in a vertical direction of the body.

5 . The dishwasher of claim 4 , wherein the basket is supported by a top end of the driving device and reciprocates to a bottom end of the driving device while being connected to the driving device.

6 . The dishwasher of claim 5 , wherein the basket moves downward to the bottom end of the driving device while the injection nozzle sprays the washing water.

7 . The dishwasher of claim 5 , wherein the basket moves upward from the bottom end of the driving device to the top end of the driving device while the air nozzle blows the air.

8 . The dishwasher of claim 1 , wherein the basket reciprocates at least once while being connected to the driving device while the injection nozzle sprays the washing water.

9 . The dishwasher of claim 1 , wherein the basket reciprocates at least once while being connected to the driving device while the air nozzle blows the air.

10 . The dishwasher of claim 1 , wherein the air nozzle blows the air to pressurize and remove moisture on a surface of the dish using air pressure.

11 . The dishwasher of claim 10 , wherein an air blower configured to supply the air to the air nozzle is provided in the body.

12 . The dishwasher of claim 11 , wherein the air nozzle comprises a supply pipe provided to receive the air supplied by the air blower, and
wherein one or more bent portions are provided in a part of the supply pipe to be adjacent to an outside of the washing tub.

13 . The dishwasher of claim 1 , wherein the basket driver comprises:
a motor configured to generate a driving force; a belt connected to a driving pulley and an idle pulley and configured to rotate to transfer the driving force of the motor to the basket; and a rail configured to guide a movement of the basket.

14 . The dishwasher of claim 13 , wherein the rail has a pipe shape which has an internal space and an opening at one side thereof.

15 . The dishwasher of claim 14 , wherein the belt is disposed in the internal space of the rail, and
wherein the basket driver further comprises a belt holder coupled to a tooth form of the belt and configured to move together with the belt in the internal space of the rail.

16 . The dishwasher of claim 14 , wherein the basket driver further comprises a basket holder provided to surround an outer surface of the rail, is configured to move together with the belt holder while being coupled to the belt holder through the opening of the rail, and is coupled to the basket.

17 . A dishwasher comprising:
a body; a washing tub provided inside the body of the dishwasher; a basket provided to accommodate a dish; an injection nozzle configured to spray washing water toward the basket; and a basket driver configured to drive the basket to pass by the injection nozzle and reciprocate while the injection nozzle sprays the washing water such that the dish in the basket is washed.

18 . The dishwasher of claim 17 , wherein an opening is provided at one side of the washing tub such that the dish is insertable into the opening, and
wherein the dish is inserted into the opening, is accommodated in the basket, and is moved to the other side of the washing tub while the injection nozzle is operated to wash the dish.

19 . The dishwasher of claim 18 , further comprising an air nozzle configured to blow air to remove moisture on a surface of the dish using air pressure, and
wherein the basket is returned toward the opening of the washing tub while the air nozzle is operated to dry the dish.

20 . A dishwasher comprising:
a body; a washing tub provided inside the body of the dishwasher; an injection nozzle configured to spray washing water toward a dish; an air nozzle configured to blow air toward the dish; a basket configured to accommodate the dish and to reciprocate by the injection nozzle and the air nozzle; and a motor configured to drive the reciprocation of the basket based on an operation of the injection nozzle and an operation of the air nozzle.
