A washing machine includes a cabinet, a washing tub disposed in the cabinet, a detergent supply device to supply detergent to the washing tub, a valve housing, having valve devices to control water supply, connected to the detergent supply device, a coupling pipe coupled to a water supply hose outside the cabinet to guide water into the cabinet, and a connection pipe to connect the valve housing to the coupling pipe, wherein the valve housing is directly coupled to the detergent supply device, and the connection pipe is fixed to the valve housing and the coupling pipe.
1. A washing machine comprising:
a cabinet forming an external appearance thereof;
a washing tub disposed in the cabinet;
a detergent supply device to supply water and detergent to the washing tub;
a valve housing, having a plurality of valve devices to control water supply, connected to the detergent supply device on one side of the valve housing and comprising a pair of introduction pipes provided on another side of the valve housing;
a bracket which includes a pair of coupling pipes which are each configured to be coupled to a respective water supply hose outside the cabinet, and a support plate to hold the pair of coupling pipes;
a pair of connection pipes, made of a different material than the pair of coupling pipes, connecting the pair of introduction pipes and the pair of coupling pipes, each of the connection pipes being connected to one of the introduction pipes on one end and connected on another end to one of the coupling pipes;
an assembly port formed at a rear of the cabinet such that the pair of coupling pipes extend outside of the cabinet through the assembly port; and
a fixing socket to fix the pair of coupling pipes to the cabinet,
wherein
the valve housing comprises a plurality of first discharge pipes directly coupled to the detergent supply device and a plurality of second discharge pipes coupled to a device other than the detergent supply device.
2. The washing machine according to claim 1 , wherein the bracket further comprises a socket coupling part protruding from the support plate.
3. The washing machine according to claim 1 , wherein
the fixing socket comprises a socket body and a flange formed by bending one end of the socket body,
the socket body is fitted in the assembly port so as to be coupled to the bracket, and
the flange is fixed to the outside of the cabinet.
4. The washing machine according to claim 1 , wherein the pair of connection pipes and the pair of introduction pipes are made of same materials.
5. The washing machine according to claim 1 , wherein
each of the connection pipes comprises a, connection coupling protrusion disposed on the another end which protrudes outwardly from an outer circumferential surface of the connection pipe, the connection coupling protrusion being connectable to the one coupling pipe connected to the connection pipe, to fix the connection pipe to the bracket.
6. The washing machine according to claim 5 , wherein the bracket further comprises a bracket coupling protrusion disposed on the bracket to correspond to the connection coupling protrusion, to fix the connection pipe to the bracket.
7. The washing machine according to claim 5 , wherein the pair of connection pipes are disposed in parallel, and
a fixing member is disposed between the pair of connection pipes to connect the pair of connection pipes.
8. A method of assembling the washing machine of claim 1 , the method comprising:
preparing the cabinet to be open at a top and a front thereof, the cabinet having the assembly port formed at the rear of the cabinet;
assembling the detergent supply device, the valve housing to be connected to the detergent supply device and the bracket to be connected to the valve housing and to be coupled to the respective water supply hoses outside the cabinet which are provided to guide water into the valve housing, the assembled detergent supply device, valve housing, and bracket together forming a generally rigid water supply unit assembly;
assembling a front plate to the cabinet so as to form an edge at which the top and the front of the cabinet join each other;
shifting the bracket through the assembly port from an inside to the outside of the cabinet so that the water supply unit assembly is placed in the cabinet; and
adjusting a position of the water supply unit assembly in the cabinet so that the water supply unit assembly is fixedly mounted in the cabinet.
9. The method according to claim 8 , wherein the front plate is first assembled and then the water supply unit assembly is assembled.
