Abstract

A window air conditioner includes a housing including a separation groove dividing the housing into two parts, a mounting base movably mounted in the separation groove, and a sealing member connected with the mounting base. The sealing member is fitted with the mounting base by deformation, and the sealing member is configured to be driven by the mounting base to switch between a storage state and a working state. In the storage state, the sealing member is received in the separation groove. In the working state, the sealing member is at least partially outside the separation groove.

First claim

What is claimed is:

1. A window air conditioner comprising:
a housing including a separation groove dividing the housing into two parts;
a mounting base movably mounted in the separation groove, the mounting base including:
a bottom mounting plate rotatably mounted in the separation groove;
two side mounting plates formed at opposite sides of the bottom mounting plate, respectively, wherein the two side mounting plates together with the bottom mounting plate form a mounting slot, each of the two side mounting plates includes a guiding protrusion bar that protrudes toward the opposite side of the bottom mounting plate; and
a rotation arm protruding from a bottom of the mounting base;

a sealing member connected with the mounting base and received in the mounting slot, the sealing member being fitted with the mounting base by deformation; and
a fixation base mounted in the separation groove, the fixation base including:
a bottom fixation plate; and
a first side fixation plate and a second side fixation plate on opposite sides of the bottom fixation plate, respectively, a receiving groove being formed between the first side fixation plate and the second side fixation plate;

wherein:
the mounting base is configured to rotate the sealing member to switch between:
a storage state, in which the sealing member is received in the separation groove; and
a working state, in which the sealing member is at least partially outside the separation groove;

the rotation arm is rotatably connected to the fixation base through a shaft hole and a rotation shaft fitted in the shaft hole; and
a boss extending towards the receiving groove protrudes on the first side fixation plate, the shaft hole being formed in the boss.

2. The window air conditioner of claim 1 , wherein:
the guiding protrusion bar has an elongated shape and extends along an insertion direction of the mounting slot.

3. The window air conditioner of claim 2 , wherein for each side mounting plate:
the guiding protrusion bar includes a root connected to an inner wall surface of the side mounting plate and a top away from the inner wall surface of the side mounting plate; and
a thickness of the guiding protrusion bar gradually decreases from the root to the top.

4. The window air conditioner of claim 2 , wherein for each side mounting plate:
the guiding protrusion bar includes a root connected to an inner wall surface of the side mounting plate and a top away from the inner wall surface of the side mounting plate; and
the guiding protrusion bar is inclined towards a bottom wall of the mounting slot from the root to the top.

5. The window air conditioner of claim 2 , wherein a guiding slope is formed at an end of the guiding protrusion bar, the guide slope being inclined along the insertion direction of the mounting slot.

6. The window air conditioner of claim 1 , wherein:
each of the two side mounting plates includes a groove formed at an outer wall surface of the side mounting plate; and
the groove has an elongated shape and extends along an insertion direction of the mounting slot.

7. The window air conditioner of claim 1 , wherein a sink groove for mounting the fixation base is provided at a bottom of the separation groove, the sink groove including a drain hole configured to drain water.

8. The window air conditioner of claim 1 , wherein:
the rotation arm extends into the receiving groove; and
the shaft hole is formed at one of the first side fixation plate and the rotation arm, and the rotation shaft is formed at another one of the first side fixation plate and the rotation arm.

9. The window air conditioner of claim 8 , wherein a rotation angle of the rotation arm of the mounting base is adjustable.

10. The window air conditioner of claim 9 , wherein:
a plurality of positioning grooves are formed at the one of the first side fixation plate and the rotation arm on a periphery of the shaft hole;
a positioning protrusion is formed at the other one of the first side fixation plate and the rotation arm on a periphery of the rotation shaft; and
the positioning protrusion is configured to cooperate with one of the positioning grooves to position the mounting base when the mounting base rotates to a preset angle.

11. The window air conditioner of claim 8 , wherein:
a rotation portion is formed at a tail end of the rotation arm, the rotation portion including two opposite side walls, and the rotation shaft protruding on one of the side walls.

12. The window air conditioner of claim 11 , wherein a plurality of connection plates are formed between the two side walls of the rotation portion, and a hollow groove is formed between two adjacent ones of the connection plates.

13. The window air conditioner of claim 11 , wherein the fixation base further includes:
two rib plates on a surface of the first side fixation plate that faces away from the boss; and
a cover plate on a side edge of the first side fixation plate that faces away from the bottom fixation plate, the cover plate being connected to the two rib plates and, together with the two rib plates, forming an avoiding groove corresponding to the shaft hole.

14. The window air conditioner of claim 13 , wherein a lower end of one of the rib plates is chamfered to form a guiding portion at a chamfered position of the one of the rib plates.

15. A window air conditioner comprising:
a housing including a separation groove dividing the housing into two parts;
a mounting base movably mounted in the separation groove, the mounting base including:
a bottom mounting plate rotatably mounted in the separation groove;
two side mounting plates formed at opposite sides of the bottom mounting plate, respectively, wherein the two side mounting plates together with the bottom mounting plate form a mounting slot, each of the two side mounting plates includes a guiding protrusion bar that protrudes toward the opposite side of the bottom mounting plate; and
a rotation arm protruding from a bottom of the mounting base;

an elastic sealing member configured to be coupled to the housing and received in the mounting slot, the sealing member being fitted with the mounting base by deformation, and the sealing member being configured to rotate with the mounting base; and
a fixation base mounted in the separation groove, the fixation base including:
a bottom fixation plate; and
a first side fixation plate and a second side fixation plate on opposite sides of the bottom fixation plate, respectively, a receiving groove being formed between the first side fixation plate and the second side fixation plate;

wherein:
the rotation arm is rotatably connected to the fixation base through a shaft hole and a rotation shaft fitted in the shaft hole; and
a boss extending towards the receiving groove protrudes on the first side fixation plate, the shaft hole being formed in the boss.

16. The window air conditioner of claim 15 , wherein the elastic sealing member is configured to switch between:
a storage state, in which the sealing member is received in the separation groove; and
a working state, in which the sealing member is at least partially outside the separation groove.

17. A window air conditioner comprising:
a housing including a separation groove dividing the housing into two parts, a sink groove being provided at a bottom of the separation groove and including a drain hole configured to drain water;
