## Abstract

A washing machine including a body including a front frame; a tub provided inside the body; a dispenser to supply water to the tub; a diaphragm provided between the tub and the front frame, the diaphragm including a through hole formed on one side; a nozzle to spray the water toward an inside of the tub; and a supply hose formed to surround the nozzle while a portion of the nozzle is inside the through hole of the diaphragm, wherein a first side of the supply hose is formed to be coupled with the dispenser, and a second side of the supply hose is formed to extend toward an inside of the diaphragm through the through hole.

## Claims

### Claim 1

A washing machine comprising:
a body including a front frame;
a tub arrangeable inside the body;
a dispenser to supply water to the tub while the tub is arranged inside the body;
a diaphragm arrangeable between the tub and the front frame, the diaphragm including a through hole formed on one side;
a nozzle to spray the water toward an inside of the tub, the nozzle being arrangeable inside the through hole of the diaphragm; and
a supply hose formed to surround the nozzle such that while a portion of the nozzle is arranged inside the through hole of the diaphragm, the supply hose is between the diaphragm and the portion of the nozzle,
wherein a first side of the supply hose is formed to be coupled with the dispenser, and a second side of the supply hose is formed to extend toward an inside of the diaphragm through the through hole.

### Claim 2 (depends on 1)

The washing machine of claim 1, wherein the diaphragm comprises:
a protrusion formed around the through hole to surround a portion of the supply hose; and
a side wall formed to extend outward from an outer surface of the protrusion.

### Claim 3 (depends on 2)

The washing machine of claim 2, wherein the second side of the supply hose comprises:
a first extension having a portion formed to be in contact with an inner surface of the protrusion of the diaphragm; and
a second extension formed to be bent from the first extension, and extend along an inner surface of the side wall of the diaphragm.

### Claim 4 (depends on 3)

The washing machine of claim 3, wherein the first extension of the supply hose comprises a guide rib formed to protrude from an outer surface, be in contact with one end of the protrusion of the diaphragm, and be fixed to the diaphragm.

### Claim 5 (depends on 3)

The washing machine of claim 3, wherein the first extension of the supply hose comprises a coupling groove, coupleable with the nozzle, on one side of an inner surface of the first extension.

### Claim 6 (depends on 5)

The washing machine of claim 5, wherein the nozzle comprises:
a first member formed to be provided on the inner surface of the first extension of the supply hose and extend along the first extension; and
a second member formed to be connected to the first member, and extend along the second extension of the supply hose, and be fixed to the supply hose.

### Claim 7 (depends on 6)

The washing machine of claim 6, wherein a projection is formed at one side of an outer surface of the first member of the nozzle, and the projection is formed to protrude toward the coupling groove to be coupled with the coupling groove.

### Claim 8 (depends on 6)

The washing machine of claim 6, wherein the nozzle further comprises a third member formed to extend from a connection portion of the first member and the second member of the nozzle, and be inclined downward toward the tub, and guide water to be supplied to the tub.

### Claim 9 (depends on 1)

The washing machine of claim 1, wherein the supply hose comprises at least one rib formed at a portion of the supply hose on an outer surface and be in contact with the body, the portion of the supply hose formed to face the body, to prevent the supply hose from colliding with the body.

### Claim 10 (depends on 9)

The washing machine of claim 9, wherein the at least one rib is a first rib provided at a first portion of the supply hose, the first portion of the supply hose formed to face the front frame, and
a second rib is provided at a second portion of the supply hose, the second portion formed to face a side frame of the body.

### Claim 11 (depends on 10)

The washing machine of claim 10, wherein each of the first rib and the second rib is in a shape of a bar.

### Claim 12 (depends on 11)

The washing machine of claim 11, wherein each of the first rib and the second rib is formed to extend along a direction that is perpendicular to an extension direction of the supply hose, and is among a plurality of ribs spaced a preset distance from each other.

### Claim 13

A washing machine comprising:
a body;
a tub arrangeable inside the body;
a diaphragm including a side wall that has a through hole on one side, and a protrusion formed to extend upward from the side wall;
a nozzle formed to be connected to the diaphragm, and spray water toward an inside of the tub, the nozzle being arrangeable inside the through hole of the diaphragm; and
a supply hose formed to be coupled with an inner surface of the diaphragm and surround the nozzle such that while a portion of the nozzle is arranged inside the through hole of the diaphragm, the supply hose is between the diaphragm and the portion of the nozzle.

### Claim 14 (depends on 13)

The washing machine of claim 13, wherein the supply hose comprises:
a first extension having a portion formed to be in contact with an inner surface of the protrusion of the diaphragm; and
a second extension formed to be bent from the first extension, and extend along an inner surface of the side wall of the diaphragm.

### Claim 15 (depends on 14)

The washing machine of claim 14, wherein the first extension comprises a guide rib formed to protrude from an outer surface, be in contact with one end of the protrusion of the diaphragm, and be fixed to the diaphragm.
