Abstract

There is provided a dish washing machine, including a main body; a washing tank provided inside the main body; and a fixed nozzle assembly fixed in one side of the washing tank and configured to jet washing water, wherein the fixed nozzle assembly includes, a nozzle body having a jet nozzle configured to jet washing water; and a nozzle front cover combined with a front surface of the nozzle body, and wherein the nozzle front cover and/or the nozzle body include corresponding ribs to cover a combining portion between the nozzle front cover and the nozzle body to minimize a foreign substance from being introduced into the combining portion of the nozzle front cover and the nozzle body. According to such a configuration, it is possible to minimize contaminants from accumulating in the fixed nozzle assembly.

Claims

1. A dish washing machine, comprising:

a main body;

a washing tank provided inside the main body; and

a fixed nozzle assembly fixed in one side of the washing tank and configured to jet washing water,

a vane configured to reflect the washing water from the fixed nozzle assembly to the dish while linearly moving;

a rail guiding the vane to linearly move; and

wherein the vane includes;

a cap portion provided at a center of the vane and coupled to the rail,

a first reflection portion extending from the cap portion in a first direction,

a second reflection portion extending from the cap portion in a second direction opposite to the first direction,

wherein the fixed nozzle assembly includes a first fixed nozzle disposed to correspond to the first reflection portion, and a second fixed nozzle disposed to correspond to the second reflection portion.

2. The dish washing machine according to claim 1,

wherein the rail extending in a direction orthogonal to the first direction at a center portion of a bottom plate of the washing tank, and

washing tank includes a first region positioned in the first direction from the rail and a second region positioned in the second direction from the rail.

3. The dish washing machine according to claim 2,

wherein the first reflecting portion and the first fixed nozzle are disposed on the first region, and the second reflecting portion and the second first fixed nozzle are disposed on the second region.

4. The dish washing machine according to claim 3, further comprising a control unit for controlling the injection of the fixed nozzle assembly, and

wherein the control unit is configured to control the injection of the fixed nozzle assembly so that the washing water is jetted from at least one of the first fixed nozzle and the second fixed nozzle.

5. The dish washing machine according to claim 4,

wherein the control unit is configured to control the injection of the fixed nozzle assembly so that the fixed nozzle assembly is selectively clean the tableware on the first region and the tableware on the second region.

6. The dish washing machine according to claim 4,

wherein the control unit is configured to control the injection of the fixed nozzle assembly so that the fixed nozzle assembly is clean both the tableware on the first region and the tableware on the second region.

7. The dish washing machine according to claim 1, further comprising a distribution device for distributing the washing water, and

wherein the distribution device is provided to independently distribute washing water to the first fixed nozzle and the second fixed nozzle.

8. The dish washing machine according to claim 7, wherein the distribution device includes a first hose connected to the first fixed nozzle and a second hose connected to the second fixed nozzle.

9. The dish washing machine according to claim 8, further comprising a control unit for controlling the distribution device, and

wherein the control unit is configured to control the distribution device so that the distribution device supply the washing water to at least one of the first hose and the second hose.
