Abstract

Disclosed are a dish rack and dishwasher having the same. The present invention includes a wash tub forming a wash space, a rack configured to store a dish by being drawably provided within the wash tub, and a plurality of spray units configured to spray water upon the rack, wherein the rack comprises a frame configured to store a dish, a moving roller unit coupled with the frame to move upward and downward, the moving roller unit supporting a guide rail to draw the frame, and a location adjusting unit coupled with the frame, the location adjusting unit configured to selectively fix an upward/downward movement of the moving roller unit and release a fixed state of the moving roller unit to enable the upward/downward movement of the moving roller unit.

First claim

What is claimed is:

1. A rack comprising:
a frame configured to store a dish;
a moving roller unit that comprises a multitude of latch sills and that is coupled with the frame to move upward and downward, the moving roller unit supporting a guide rail to draw the frame; and
a location adjusting unit coupled with the frame, the location adjusting unit configured to selectively fix an upward/downward movement of the moving roller unit and release a fixed state of the moving roller unit to enable the upward/downward movement of the moving roller unit,
wherein the location adjusting unit comprises:
a housing fixed to the frame,
a rotation lever configured to rotate by receiving a pressure in a direction crossing with a moving direction of the frame, wherein the rotation lever comprises a button projection exposed from the housing externally by being rotatably coupled with the housing and a rotation portion configured to be rotated by a pressure applied to the button projection, and
a rotation latch part configured to release a locked state of the latch sill by receiving a rotation force of the rotation lever, wherein the rotation latch part comprises an interworking portion configured to interwork with the rotation portion by being rotatably coupled with the housing, a latch projection configured to be supported by the latch sill by extending from the interworking portion, and a spring configured to pressurize the latch projection toward the latch sill.

2. The rack of claim 1 , the frame comprising:
an outer frame in a horizontal chain shape;
a vertical frame arranged in a drawing direction of the frame; and
a horizontal frame arranged to cross with the vertical frame by being connected to the outer frame and the vertical frame.

3. The rack of claim 2 , further comprising a frame cover configured to cover a top side of the outer frame in a manner of being coupled with the top side of the outer frame.

4. The rack of claim 3 , wherein the moving roller unit and the location adjusting unit are provided in a symmetric configuration to each of both sides of a drawing direction of the frame.

5. The rack of claim 4 , wherein the frame cover is configured to extend between the location adjusting unit provided to both sides of the frame.

6. The rack of claim 3 , wherein a top side of location adjusting unit is configured to form a portion of a top side of the frame and extend along a top side of the frame cover.

7. The rack of claim 2 , wherein the location adjusting unit comprises a housing configured to form an outer portion of the outer frame and have a handle formed in a prescribed inner portion and wherein the horizontal frame and the vertical frame extend near the housing.

8. The rack of claim 2 , wherein the location adjusting unit comprises a housing configured to be fixed to the outer frame and have a handle formed in a prescribed inner portion, wherein the handle comprises a handle space portion perforating the housing, and wherein the horizontal frame and the vertical frame extend near the handle space portion.

9. The rack of claim 1 , the moving roller unit comprising:
an upper roller supporting an upper part of the guide rail; and
a lower roller supporting a lower part of the guide rail.

10. The rack of claim 1 , wherein a top side of the location adjusting unit forms a portion of a top side of the frame.

11. A rack comprising:
a frame configured to store a dish;
a moving roller unit that comprises a multitude of latch sills and that is coupled with the frame to move upward and downward, the moving roller unit supporting a guide rail to draw the frame; and
a location adjusting unit coupled with the frame, the location adjusting unit configured to selectively fix an upward/downward movement of the moving roller unit and release a fixed state of the moving roller unit to enable the upward/downward movement of the moving roller unit,
wherein the location adjusting unit comprises:
a housing fixed to the frame,
a latch part configured to move in a direction in parallel with a drawing direction of the frame and be selectively caught on the multitude of latch sills to move a location of the latch part, wherein the latch part comprises a knob exposed through the housing and a latch projection configured to be selectively caught on the latch sill in response to a movement of the knob,
a spring configured to pressurize the latch projection toward the latch sill, and
a display part configured to indicate the location of the latch part.

12. The rack of claim 11 , wherein the display part is formed on a top side of the housing near the knob.

13. The rack of claim 11 , wherein the frame comprises:
an outer frame in a horizontal chain shape,
a vertical frame arranged in a drawing direction of the frame, and
a horizontal frame arranged to cross with the vertical frame by being connected to the outer frame and the vertical frame.

14. The rack of claim 13 , further comprising:
a frame cover configured to cover a top side of the outer frame in a manner of being coupled with the top side of the outer frame.

15. The rack of claim 14 , wherein the moving roller unit and the location adjusting unit are provided in a symmetric configuration to each of both sides of a drawing direction of the frame.

16. The rack of claim 15 , wherein the frame cover is configured to extend between the location adjusting unit provided to both sides of the frame.

17. The rack of claim 14 , wherein a top side of the location adjusting unit is configured to form a portion of a top side of the frame and extend along a top side of the frame cover.

18. The rack of claim 11 , wherein the moving roller unit comprises:
an upper roller supporting an upper part of the guide rail, and
a lower roller supporting a lower part of the guide rail.
