Abstract

A household appliance includes a connection mechanism fixing a door and a main body. The connection mechanism includes first and second components fixed by first and second fixing mechanisms. The first mechanism includes a first fixing member, a first hole on the first component and a second hole on the second component. The second mechanism includes a second fixing member, third holes elongated in a second direction at intervals on the first component and fourth holes at intervals in a first direction on the second component. When the second fixing member passes through a third hole and a fourth hole, the third and fourth holes define a distance between centers of remaining third holes and centers of remaining fourth holes in the first direction. The fourth holes adjust positions relative to the third holes in the second direction, causing the first and second components to relatively rotate.

First claim

The invention claimed is:

1. A household appliance, comprising:
a main body;
a door connected to said main body; and
a connection mechanism configured to fix said door to said main body, said connection mechanism including first and second components and first and second fixing mechanisms configured to fix said first and second components;
said first fixing mechanism having a first hole located on said first component, a second hole located on said second component, and a first fixing member passing through said first hole and said second hole for fixing said first component and said second component;
said second fixing mechanism having a group of third holes located on said first component, a group of fourth holes located on said second component, and a second fixing member;
said third holes being disposed at intervals in a first direction, said fourth holes being disposed at intervals in said first direction, said third holes and said fourth holes being disposed in such a manner that upon said second fixing member passing through any one of said third holes and any one of said fourth holes corresponding to said third holes, a distance is defined between centers of a remainder of said third holes and centers of a remainder of said corresponding fourth holes in said first direction; and
said third holes being elongated holes extending in a second direction, and said fourth holes being suitable for adjusting positions relative to said third holes in said second direction, permitting said first component and said second component to rotate relative to each other about said first fixing member for adjusting a position of said door relative to said main body upon said door being closed.

2. The household appliance according to claim 1 , wherein said centers of said third holes are all disposed along one line and extend in said first direction.

3. The household appliance according to claim 1 , wherein said first hole is a kidney-shaped hole having a major axis extending in said first direction.

4. The household appliance according to claim 3 , wherein said major axis of said first hole and said centers of said third holes are all disposed along one line.

5. The household appliance according to claim 1 , wherein said first direction is perpendicular to said second direction.

6. The household appliance according to claim 1 , wherein:
said third holes are kidney-shaped holes having major axes defining extension directions in said second direction, or
said third holes are arcuate holes bending toward said first hole and having major axes defining arc segments surrounding said first hole.

7. The household appliance according to claim 1 , wherein a screw or a bolt is provided as at least one of said first fixing member or said second fixing member.

8. The household appliance according claim 1 , wherein:
said first component has a first positioning hole;
said second component has a second positioning hole corresponding to said first positioning hole;
said first positioning hole and said second positioning hole, when aligned with each other, are suitable for receiving a removable positioning member; and
when said first positioning hole and said second positioning hole are aligned with each other, said first fixing member is suitable for passing through said first hole and said second hole, and said second fixing member is suitable for passing through one of said third holes and one of said corresponding fourth holes, for placing said first component and said second component at initial relative positions.

9. The household appliance according to claim 8 , wherein said first positioning hole and said second positioning hole are both located between said first fixing mechanism and said second fixing mechanism.

10. The household appliance according to claim 8 , wherein said first positioning hole has a non-round shape.

11. The household appliance according to claim 10 , wherein said first positioning hole has a kidney-shape.

12. The household appliance according to claim 11 , wherein said first positioning hole has a major axis extending in said first direction.

13. The household appliance according to claim 11 , wherein:
a center of said first hole and said centers of said third holes are all disposed along one line and said first hole and said third holes extend in said first direction; and
said first positioning hole has a major axis located along a line connecting said center of said first hole and said centers of said third holes, or is parallel to a line connecting said center of said first hole and said centers of said third holes.

14. The household appliance according to claim 8 , wherein said first positioning hole and said second positioning hole have identical shapes and sizes.

15. The household appliance according to claim 8 , wherein a center of said first hole overlaps a center of said second hole, at said initial relative positions.

16. The household appliance according to claim 8 , wherein said second fixing member is suitable for passing through one third hole located centrally in said group of third holes and a corresponding fourth hole, at said initial relative positions.

17. The household appliance according to claim 16 , wherein a center of said third hole located centrally in said second direction overlaps a center of said corresponding fourth hole, at said initial relative positions.

18. The household appliance according to claim 8 , wherein said connection mechanism includes an initial fixing mechanism having a first initial fixing hole located on said first component and a second initial fixing hole located on said second component, and said first initial fixing hole is overlapped by said second initial fixing hole to receive a third fixing member, at said initial relative positions.

19. The household appliance according to claim 18 , wherein said initial fixing mechanism is located between said first fixing mechanism and said second fixing mechanism.

20. The household appliance according to claim 1 , wherein said second fixing member can pass through only one of said third holes and only one of said fourth holes.
