Abstract

Disclosed herein is a clothing treatment apparatus including a cabinet, a tub disposed within the cabinet, and a detergent supply device configured to supply detergent to the tub, wherein the detergent supply device includes a detergent container configured to store detergent, a housing configured to receive the detergent container and supply the detergent and water to the tub, and a connection tube including an inlet and an outlet, the inlet and the outlet are in communication with the housing so that the detergent supplied from the housing through the inlet can be stored in the connection tube.

Claims (52)

1 . A clothing treatment apparatus, comprising:

a cabinet;

a tub disposed within the cabinet; and

a detergent supply device configured to supply detergent to the tub;

wherein the detergent supply device comprises:

a detergent container configured to store detergent;

a housing configured to receive the detergent container and supply the detergent and water to the tub; and

a connection tube including an inlet and an outlet, the inlet and the outlet are in communication with the housing to allow the detergent supplied from the housing through the inlet to be stored in the connection tube and the outlet is in communication with the housing at a higher position than the inlet, and

wherein the inlet and outlet of the connection tube are in communication with a rear wall of the housing.

2 . The clothing treatment apparatus of claim 1 , wherein a center of the outlet of the connection tube is configured to communicate with the housing at a higher position than a center of the inlet.

3 . The clothing treatment apparatus of claim 2 , wherein a lower end of the outlet of the connection tube is configured to communicate with the housing at a higher position than the center of the inlet.

4 . The clothing treatment apparatus of claim 1 , wherein the housing includes a storage bin configured to receive the detergent supplied from the detergent container and communicate with the inlet of the connection tube.

5 . The clothing treatment apparatus of claim 4 , wherein:

the rear wall is disposed on a rear side of the detergent container, and includes a blocking portion defining one side of a storage space of the storage bin,

the inlet of the connection tube is configured to communicate with the blocking portion of the rear wall, and

the outlet of the connection tube is configured to communicate with a different portion of the rear wall.

6 . The clothing treatment apparatus of claim 4 , further comprising a detergent pump configured to supply detergent from the detergent container to the housing,

wherein the housing includes a housing outlet hole forming a passage configured to move the detergent in the detergent container to the detergent pump, and a housing inlet hole configured to supply the detergent passing through the detergent pump into the housing, and

wherein the storage bin is configured to receive the detergent supplied from the housing outlet hole or the housing inlet hole.

7 . The clothing treatment apparatus of claim 6 , further comprising:

a pump connector formed protruding from a rear side of the detergent container to be coupled with the housing outlet hole of the housing,

wherein the storage bin is configured to receive the detergent leaked from the pump connector.

8 . The clothing treatment apparatus of claim 4 , further comprising a water supply pipe communicating with the housing to supply water from a water supply source into the housing,

wherein the storage bin is configured to receive the water supplied into the housing from the water supply pipe.

9 . The clothing treatment apparatus of claim 8 , wherein the connection tube forms a flow path for the detergent and the water received in the storage bin from the inlet to the outlet.

10 . The clothing treatment apparatus of claim 8 , wherein the housing includes a water collection guide formed on an upper portion of the storage bin and inclined downwardly toward the storage bin to guide the water supplied from the water supply pipe to the storage bin.

11 . The clothing treatment apparatus of claim 4 , wherein a combined volume of the connection tube and the storage bin is greater than or equal to a maximum amount of detergent that may leak from the detergent supply device.

12 . The clothing treatment apparatus of claim 1 , wherein:

the housing includes:

a washing water outlet hole connected to the inlet of the connection tube, and

a washing water inlet hole connected to the outlet of the connection tube, and

a center of the washing water outlet hole is located at a lower position than a center of the washing water inlet hole.

13 . The clothing treatment apparatus of claim 12 , wherein the center of the washing water outlet hole is located at a lower position than a lower end of the washing water inlet hole.

14 . The clothing treatment apparatus of claim 1 , wherein the connection tube is bent in a U shape.

15 . The clothing treatment apparatus of claim 1 , wherein the detergent container is detachably disposed in the housing.

16 . The clothing treatment apparatus of claim 1 , wherein the housing includes a guide channel elongating on a bottom of the housing to guide the water and detergent introduced into the housing through the outlet of the connection tube to the tub.

17 . A clothing treatment apparatus includes:

a cabinet,

a tub disposed within the cabinet having an opening on an upper portion thereof, and

a detergent supply device disposed on an upper side the tub, wherein the detergent supply device includes:

a housing,

a detergent container configured to supply detergent to the housing,

a connection tube communicating with the housing and capable of receiving water and detergent supplied to the housing,

wherein a height of an inlet through which the connection tube is supplied with water and the detergent from the housing is lower than a height of an outlet through which the connection tube is supplied with water and detergent to the housing, and

wherein the inlet and outlet of the connection tube are in communication with a rear wall of the housing.

18 . The clothing treatment apparatus of claim 17 , wherein:

the housing includes a storage bin configured to store detergent supplied from the detergent container and water supplied from a water supply pipe, and

the inlet of the connection tube may communicate with the storage bin.

19 . The clothing treatment apparatus of claim 18 , wherein a combined volume of the connection tube and the storage bin is greater than or equal to a maximum amount of detergent that may leak from the detergent supply device.

20 . The clothing treatment apparatus of claim 17 , wherein a center of the inlet is located lower than a center of the outlet.

21 . The clothing treatment apparatus of claim 17 , wherein a center of the inlet is located lower than a bottom of the outlet.

22 . The clothing treatment apparatus of claim 17 , wherein the connection tube is bent in a U shape.
