Abstract

A household appliance has a main body, a chamber with an opening, and a drawer door closing the chamber. A support mechanism is connected between the drawer door and the main body. A cable extends between the main body and the drawer door and a guidance mechanism guides the cable and moves with the drawer door. The guidance mechanism includes a bendable member that moves along a moving path including a bent portion. A limiting mechanism limits the bendable member to move within the moving path and a preset error range. A structure of a component surrounding the guidance mechanism in the household appliance is improved, so that a moving track of the guidance mechanism can be guided and limited when the guidance mechanism moves as the drawer door moves. This helps the guidance mechanism and the cable move through an expected track.

First claim

The invention claimed is:

1. A household appliance, comprising:
a main body containing a chamber with an opening;
a drawer door configured to selectively close or open said chamber;
a support mechanism disposed between said drawer door and said main body and movably connecting said drawer door to said main body;
said support mechanism having a fixed rail fixedly secured on said main body;
a cable extending from said main body to said drawer door and guiding a chain of said cable; and
a limiting mechanism having a limiting member and a mounting portion configured to firmly secure said limiting member to said fixed rail, said limiting member being configured to limit a moving range of said chain;
said mounting portion having a main body portion and a pair of claw structures, wherein said claw structures are connected to upper and lower ends of said main body portion, and wherein said claw structures have shapes that correspond to outer profile parts of said fixed rail.

2. The household appliance according to claim 1 , wherein said mounting portion is substantially C-shaped.

3. The household appliance according to claim 1 , wherein said limiting member is engaged on a side of said fixed rail facing a side wall of said chamber.

4. The household appliance according to claim 1 , wherein said limiting member comprises a stop portion disposed below said fixed rail.

5. The household appliance according to claim 4 , wherein said stop portion comprises a first end and a second end opposite one another, wherein said first end is connected to said mounting portion and said second end extends in a direction away from a side wall of said chamber to which said fixed rail is mounted.

6. The household appliance according to claim 4 , wherein said stop portion comprises a reinforcing rib.

7. The household appliance according to claim 1 , wherein said support mechanism includes said fixed rail, a movable rail, and a support frame, and wherein said movable rail is configured to movably connect said fixed rail to said support frame.

8. The household appliance according to claim 7 , wherein said support frame is connected to a side of said drawer door facing said chamber.

9. The household appliance according to claim 7 , wherein said movable rail and said support frame are assembled by a hook structure, and said hook structure is exposed through a relief hole formed on said support frame.

10. A household appliance, comprising:
a main body containing a chamber with an opening;
a drawer door configured to selectively close or open said chamber;
a support mechanism disposed between said drawer door and said main body and movably connecting said drawer door to said main body;
said support mechanism having a fixed rail fixedly secured on said main body;
a cable extending from said main body to said drawer door and guiding a chain of said cable; and
a limiting mechanism having a limiting member and a mounting portion configured to firmly secure said limiting member to said fixed rail;
said limiting member being configured to limit a moving range of said chain;
said mounting portion having a main body portion and a pair of claw structures, wherein said claw structures are connected to upper and lower ends of said main body portion, and wherein said main body portion is formed with a limiting hole configured to adapt to a coupling portion of said fixed rail.

11. A household appliance, comprising:
a main body containing a chamber with an opening;
a drawer door configured to selectively close or open said chamber;
a support mechanism disposed between said drawer door and said main body and movably connecting said drawer door to said main body;
said support mechanism having a fixed rail fixedly secured on said main body;
a cable extending from said main body to said drawer door and guiding a chain of said cable; and
a limiting member connected to said fixed rail, said limiting member being configured to limit a moving range of said chain, said limiting member having a stop portion disposed below said fixed rail, and
wherein said stop portion comprises a sheet-like body that is substantially plate-shaped and that is parallel to a horizontal plane.

12. The household appliance according to claim 11 , wherein the limiting member comprises a mounting portion configured to firmly secure said limiting member to said fixed rail.

13. The household appliance according to claim 12 , wherein said mounting portion comprises a main body portion and a pair of claw structures, wherein said claw structures are connected to upper and lower ends of said main body portion.

14. The household appliance according to claim 13 , wherein said claw structures have shapes that correspond to outer profile parts of said fixed rail.
