Abstract

A wall-mounted drum-type washing machine includes a rear panel mounted on a wall surface; a tub containing wash water; a rotatable drum in the tub; a driving unit providing power to the drum; a coupling unit on the rear panel coupled to a rotatable driving shaft of the drum; and a disposition portion preventing the driving unit connected to the driving shaft from interfering with the wall surface.

First claim

The invention claimed is:

1. A wall-mounted drum-type washing machine comprising:
a rear panel mounted on a wall surface;
a tub containing wash water;
a rotatable drum disposed in the tub and including a rotatable driving shaft;
a driving unit providing power to the drum;
a rotation hole in the rear panel;
a bearing portion in the rotation hole configured to rotatably support the driving shaft; and
a disposition portion comprising a concave recess on the rear panel, wherein the driving unit is disposed inside the disposition portion, and
wherein:
the rear panel comprises a protrusion;
a water level sensor is disposed on the protrusion;
the protrusion comprises an attachment hole for removably attaching the water level sensor;
the protrusion protrudes from the rear panel to a front side;
the attachment hole is disposed on a top surface of the protrusion; and
the water level sensor is disposed on a front surface of the protrusion.

2. The wall-mounted drum-type washing machine of claim 1 , wherein the driving unit comprises:
a motor providing power to rotate the drum;
a driving wheel connected to the driving shaft; and
a belt transmitting the power from the motor to the driving wheel.

3. The wall-mounted drum-type washing machine of claim 2 , wherein the motor has a fixing hole therein, the rear panel has a plurality of boss portions on the front side, and the fixing hole is inserted into one of the boss portions.

4. The wall-mounted drum-type washing machine of claim 1 , further comprising:
a front panel on the tub, the front panel having an opening therein; and
a hinge connected to a door for opening/closing the opening and supported by the front panel.

5. The wall-mounted drum-type washing machine of claim 4 , further comprising:
a box unit on the rear panel and surrounding the tub; and
a cover unit on the box unit and covering the front panel,
wherein the hinge is supported by a fastening member on the front panel and extends through the cover unit.

6. A wall-mounted drum-type washing machine comprising:
a rear panel mounted on a wall surface;
a tub containing wash water;
a rotatable drum disposed in the tub;
a disposition portion comprising a concave portion of a rear surface of the rear panel;
a first set of reinforcement ribs disposed on a center portion of the rear surface of the rear panel;
a second set of reinforcement ribs disposed on the rear surface of the rear panel, wherein the second set of reinforcement ribs is longer than the first set of reinforcement ribs;
a driving unit providing power to the drum and disposed inside of the disposition portion; and
a coupling unit disposed on the rear panel and coupled to a rotatable driving shaft of the drum,
wherein:
the disposition portion is configured to prevent the driving unit connected to the driving shaft from interfering with the wall surface;
the first and second set of reinforcement ribs are configured to support the rear panel to prevent the rear panel from being deformed by vibrations generated by a rotation of the rotatable drum;
the rear panel comprises a protrusion;
a water level sensor is disposed on the protrusion;
the protrusion comprises an attachment hole for removably attaching the water level sensor;
the protrusion protrudes from the rear panel to a front side;
the attachment hole is disposed on a top surface of the protrusion; and
the water level sensor is disposed on a front surface of the protrusion.
