Abstract

Disclosed is a washing machine having an improved structure so as to enable noise reduction. The disclosed washing machine comprises: a main body; a drum rotatably disposed inside the main body; and a detergent supply device provided in the main body and supplying detergent into the drum, wherein the detergent supply device includes: a housing; a detergent container containing the detergent and movably coupled to the housing; and a water supply frame having an inflow hole through which water supplied from the outside flows in, and a flow velocity mitigation part provided at the lower side of the inflow hole so as to mitigate the flow velocity of the water.

First claim

1 . A washing machine comprising:
a main body; a drum configured to be rotatably disposed in the main body; and a detergent supply device configured to be provided in the main body and supply a detergent into the drum, wherein the detergent supply device includes a housing, a detergent container configured to contain the detergent and be movably coupled to the housing, and a water supply frame configured to include an inflow hole into which water supplied from the outside is introduced, and a flow velocity reducer provided on a downstream side of the inflow hole and reducing a flow velocity of the water.

2 . The washing machine as claimed in claim 1 , wherein the water supply frame further includes a channel guiding the water to the detergent container, and
the channel includes a first channel and a second channel branched off from the flow velocity reducer.

3 . The washing machine as claimed in claim 2 , wherein the first channel and the second channel connect to a first section partitioned at a predetermined position of the detergent container.

4 . The washing machine as claimed in claim 3 , wherein the second channel includes a second main channel connected to the first section, and a second auxiliary channel branched off from the second main channel and supplying water to a second section.

5 . The washing machine as claimed in claim 4 , wherein the second auxiliary channel includes a second upper auxiliary channel supplying water to the second section, and a second lower auxiliary channel branched off from the second upper auxiliary channel and supplying water to a third section.

6 . The washing machine as claimed in claim 5 , wherein the water supply frame further includes a third channel spaced apart from the flow velocity reducer and supplying water to a fourth section, and
one or more spray holes spraying water to the detergent container are formed in each of the first to fourth sections.

7 . The washing machine as claimed in claim 3 , wherein the water supply frame further includes a first partition wall provided in the first section and preventing the water guided through the first channel and the second channel from being mixed.

8 . The washing machine as claimed in claim 2 , wherein the inflow hole has a cross sectional area equal to or smaller than the sum of cross sectional areas of the first channel and the second channel.

9 . The washing machine as claimed in claim 2 , wherein the channel guides the water to a first section partitioned at a predetermined position of the detergent container, and
the water supply frame further includes a bypass channel connected to the first section to discharge the water supplied to the first section to the outside.

10 . The washing machine as claimed in claim 9 , wherein the water supply frame further includes a second partition wall provided in the first section and changing a flow of the introduced water from the channel toward the bypass channel.

11 . The washing machine as claimed in claim 1 , wherein the flow velocity reducer has a cross sectional area decreasing toward a direction in which the water flows.

12 . The washing machine as claimed in claim 1 , wherein the detergent supply device further includes a cover frame coupled to an upper portion of the water supply frame and sealing the water supply frame.

13 . A detergent supply device installed in a washing machine, comprising:
a housing configured to have an opening formed in one side thereof; a detergent container configured to contain a detergent and be slidably coupled to the housing through the opening; and a water supply frame configured to be coupled to the housing and include a channel guiding water to the detergent container, an inflow hole into which water supplied from the outside is introduced, and a flow velocity reducer provided on a downstream side of the inflow hole and reducing a flow velocity of the water.

14 . The detergent supply device as claimed in claim 13 , wherein the channel includes a first channel and a second channel branched off from the flow velocity reducer.

15 . The detergent supply device as claimed in claim 13 , wherein the channel guides the water to a first section partitioned at a predetermined position of the detergent container, and
the water supply frame further includes a bypass channel connected to the first section to discharge the water supplied to the first section to the outside.
