Abstract

A wall-mounted drum type washing machine includes a rear panel forming a rear surface of a cabinet, comprising a water supply device installed to supply wash water and a driving unit to provide power for a washing operation, mounted on a wall surface; a tub in the cabinet to contain wash water, integrated with the rear panel, and having a rotatable drum therein; a box unit connected to a cover unit having a door thereon, forming an outer wall of the cabinet, and coupled to the rear panel and surrounding the tub; a water supply device supplying wash water into the tub through a top surface of the cabinet; and a drain device discharging wash water from the tub to the bottom of the box unit.

First claim

The invention claimed is:

1. A wall-mounted drum type washing machine comprising:
a rear panel forming a rear surface of a cabinet configured to be mounted on a wall surface;
a tub installed in the cabinet to contain wash water, integrated with the rear panel, and having a rotatable drum therein;
a box unit connected to a cover unit having a door thereon, forming an outer wall of the cabinet, and coupled to the rear panel and surrounding the tub;
a water supply device configured to supply wash water into the tub through a top surface of the cabinet;
a drain device configured to discharge wash water from the tub to a bottom of the box unit and
a driving unit installed on the rear panel and configured to provide power for washing operations,
wherein the rear panel has a concave mounting groove on a rear surface thereof, forming a space between the wall surface and the rear surface of the rear panel, and the driving unit is connected to the drum through the rear panel and is in the mounting groove,
wherein the water supply device comprises a water supply pipe configured to supply wash water to the tub through the rear panel, and
wherein the water supply pipe is in a connection portion formed by cutting the top circumference of the mounting groove and has an upper end protruding from a top surface of the connection portion and a lower end connected to a rear surface of the tub, and the wall-mounted drum type washing machine further comprises:
a water supply valve connected to the water supply pipe is in the connection portion, and
a cover is on the connection portion that covers the water supply valve.

2. The wall-mounted drum type washing machine of claim 1 , further comprising a gasket having one end coupled to the tub and another end in contact with the door that prevents leakage of wash water from the tub and closes a gap between the cabinet and the tub.

3. The wall-mounted drum type washing machine of claim 1 , further comprising a gasket wherein the tub has a mounting hole into which the gasket is inserted and a lock portion that protrudes from an outer circumferential surface of the tub and to which the gasket is locked and fixed, wherein the lock portion comprises:
a coupling protrusion that protrudes from an outer circumferential surface of the tub; and a lock protrusion extending from an end of the coupling protrusion in a lateral direction.

4. The wall-mounted drum type washing machine of claim 3 , wherein the gasket comprises:
a hooked body on an inside of the lock portion and surrounding outer walls of the coupling protrusion and the lock protrusion;
a passing body protruding to the outside of the tub through the mounting hole and connected to the hooked body;
a coupling body connected to the passing body and in contact with the door; and a ring spring in an end of the hooked body configured to attach the hooked body to the tub.

5. The wall-mounted drum type washing machine of claim 1 , wherein the drain device comprises:
a first drain pipe at a bottom of the tub, discharging wash water;
a second drain pipe under the first drain pipe and having a larger diameter than the first drain pipe; and
a siphon between the first and second drain pipes, connecting the first and second drain pipes and applying a siphon pressure to the first drain pipe by wash water discharged from the second drain pipe.

6. The wall-mounted drum type washing machine of claim 5 , wherein the siphon comprises:
a body having an introduction port connected to the first drain pipe and a discharge port connected to the second drain pipe;
a drain induction member having a cap shape inside the body and a space at a bottom thereof; and
a siphon induction pipe protruding upward from a bottom surface of the body that moves wash water upward and discharges the wash water through the discharge port and maintains an interval from the drain induction member and forms a flow path.

7. The wall-mounted drum type washing machine of claim 1 , wherein the rear panel is fixed to the wall surface using a fastening member fastened to the wall surface through a hole of the rear panel.

8. The wall-mounted drum type washing machine of claim 7 , further comprising a buffer member between the rear panel and the wall surface to suppress vibrations generated during a washing process from being transmitted to the wall surface.
