Abstract

A washing machine including a bubble generator. The washing machine includes a detergent box configured to store a detergent, a detergent box housing configured to accommodate the detergent box therein and a bubble generator to generate bubbles to be supplied and configured to mix water supplied to the detergent box with air.

First claim

What is claimed is:

1. A washing machine comprising:
a detergent box configured to store a detergent;
a detergent box housing configured to accommodate the detergent box therein, the detergent box housing comprising an air outflow pipe configured to protrude therefrom;
a water supply pipe configured to supply water to the detergent box;
a bubble generator disposed between the water supply pipe and the detergent box housing and configured to generate bubbles to be supplied to the detergent box by mixing water with air, the bubble generator comprising:
a first flow path pipe connected to the water supply pipe;
a second flow path pipe connected to the detergent box housing;
a connection pipe configured to connect the first flow path pipe to the second flow path pipe and to have a diameter smaller than diameters of the first flow path pipe and the second flow path pipe; and
an air inflow pipe having one end connected to the connection pipe and an other end connected to the air outflow pipe of the detergent box housing so that air accommodated in the detergent box housing flows into the bubble generator through the air outflow pipe and the air inflow pipe.

2. The washing machine of claim 1 , wherein the bubble generator further comprises a perforated plate disposed at the second flow path pipe.

3. The washing machine of claim 1 , wherein the bubble generator is disposed above the detergent box housing.

4. The washing machine of claim 3 , wherein the washing machine comprises a plurality of bubble generators and the bubble generator is one of the plurality of bubble generators, and the plurality of bubble generators are arranged in parallel.

5. The washing machine of claim 3 , wherein the detergent box housing comprises:
a detergent box accommodation body in which the detergent box is insertable to the detergent box accommodation body and withdrawable from the detergent box accommodation body; and
a detergent box cover coupled to a top of the detergent box accommodation body, and
wherein the bubble generator comprises a perforated plate disposed at one side of the detergent box cover to face the detergent box accommodation body.

6. The washing machine of claim 3 , further comprising a water pressure increasing device configured to increase water pressure of the water supplied to the bubble generator.

7. A washing machine comprising:
a tub;
a water supply device configured to supply wash water to the tub;
a detergent supply device configured to supply a detergent to the tub, the detergent supply device comprising an air outflow pipe configured to protrude therefrom;
a first water supply flow path located on an upper stream side in a direction, in which the wash water supplied by the water supply device moves, and configured to connect the water supply device to the detergent supply device;
a second water supply flow path located on a downstream side in the direction, in which the wash water supplied by the water supply device moves, and configured to connect the detergent supply device to the tub; and
a bubble generator disposed at the first water supply flow path to generate bubbles using the wash water supplied by the water supply device, the bubble generator comprising:
a first flow path pipe connected to the water supply pipe;
a second flow path pipe connected to the detergent supply device;
a connection pipe configured to connect the first flow path pipe to the second flow path pipe and to have a diameter smaller than diameters of the first flow path pipe and the second flow path pipe; and
an air inflow pipe having one end connected to the connection pipe and an other end connected to the air outflow pipe of the detergent supply device so that air accommodated in the detergent supply device flows into the bubble generator through the air outflow pipe and the air inflow pipe.

8. The washing machine of claim 7 , wherein the bubble generator further comprises a perforated plate disposed in the bubble generator and configured to comprise a plurality of openings.

9. The washing machine of claim 7 , wherein the bubble generator is separably disposed.

10. A washing machine comprising:
a tub;
a water supply device configured to supply wash water to the tub;
a detergent supply device disposed between the water supply device and the tub in a direction in which the wash water supplied by the water supply device moves, to supply a detergent to the tub, configured to comprise a detergent box in which the detergent is accommodated, and comprising an air outflow pipe configured to protrude therefrom;
a detergent box accommodation body configured to accommodate the detergent box;
a detergent box cover coupled to the detergent box accommodation body; and
a bubble generator disposed between the water supply device and the detergent supply device in the direction in which the wash water supplied by the water supply device moves, to generate bubbles using the wash water supplied by the water supply device, and configured to comprise one or more bubble generation units arranged in the detergent box cover
wherein the bubble generator comprises:
a first flow path pipe connected to the water supply pipe;
a second flow path pipe connected to the detergent supply device;
a connection pipe configured to connect the first flow path pipe to the second flow path pipe and to have a diameter smaller than diameters of the first flow path pipe and the second flow path pipe; and
an air inflow pipe having one end connected to the connection pipe and an other end connected to the air outflow pipe of the detergent supply device so that air accommodated in the detergent supply device flows into the bubble generator through the air outflow pipe and the air inflow pipe.
