Abstract

A drum type washing machine includes a main body including a cabinet, a drum in the cabinet having a rotational axis thereof parallel with the ground, and a motor configured to drive or rotate the drum; and an angle adjusting unit configured to adjust an angle of the main body from the ground and/or tilt the main body up to the angle, wherein the angle adjusting unit includes a base configured to support the main body and a driver on the base configured to tilt or raise the main body, and the angle adjusting unit is configured to tilt the main body at a rear lower end of the cabinet.

First claim

What is claimed is:

1. A drum type washing machine, comprising:
a main body comprising a cabinet, a drum in the cabinet wherein a rotational axis of the drum is parallel with the ground, and a motor configured to move the drum;
a rail on the bottom surface of the cabinet and extending in a rear-to-front direction;
a hinge coupled to the rail and configured to move backward and forward along the rail; and
an angle adjusting unit configured to adjust an angle of the main body relative to the ground, wherein the angle adjusting unit comprises:
a base configured to support the main body; and
a driver on the base configured to tilt the main body, wherein the angle adjusting unit is configured to tilt the main body at a rear lower end of the cabinet,

wherein a rotational shaft is coupled to the cabinet between side surfaces of the cabinet, wherein further the base has a guide groove in which the rotational shaft rotates and slides in the rear-to-front direction of the cabinet, and wherein the driver is rotatably connected to the hinge.

2. The drum type washing machine of claim 1 , wherein the driver is a cylinder device spaced apart or separated from the rotational shaft and configured to lift the cabinet up and down.

3. The drum type washing machine of claim 2 , wherein the cylinder device includes a piston configured to reciprocate bidirectionally.

4. The drum type washing machine of claim 3 , wherein the piston comprises a first end rotatably connected to the hinge.

5. The drum type washing machine of claim 2 , wherein the cylinder device is rotatably connected to the base.

6. The drum type washing machine of claim 1 , wherein a front blocking plate extends from a front surface of the cabinet to block a space between the front blocking plate and the base, and wherein one or more side blocking plates extend from respective side surface(s) of the cabinet to block a space between the side blocking plates and the base.

7. The drum type washing machine of claim 6 , wherein the one or more side blocking plate(s) include a side blocking plate that is proximate to the rotational shaft and configured to protect the rotational shaft.

8. The drum type washing machine of claim 1 , wherein a bottom surface of the cabinet includes a sloped surface to form an installation space between the sloped surface and a base plate of the base.

9. The drum type washing machine of claim 8 , wherein the driver of the angle adjusting unit is in the installation space between the sloped surface and the base plate.

10. The drum type washing machine of claim 3 , wherein the angle between the main body and the ground increases as displacement of the piston from the cylinder device increases.

11. The drum type washing machine of claim 3 , wherein the angle between the main body and the ground decreases as displacement of the piston from the cylinder device decreases.

12. The drum type washing machine of claim 1 , further comprising a control panel configured to receive an instruction to pivot the washing machine, cabinet and/or main body upwardly.

13. The drum type washing machine of claim 3 , wherein when the cylinder device moves the piston down, the hinge slides toward the rear side of the main body.

14. The drum type washing machine of claim 1 , wherein the angle adjusting unit is configured to tilt the main body at the rear lower end of the cabinet by pivoting the main body about the rotational shaft, causing the rotational shaft to rotate, move and slide along in the rear-to-front direction in the guide groove when the angle of the main body is adjusted and/or when the main body is tilted up to the angle.
