Abstract

Disclosed is a drum washing machine, including: a drum configured in an outer tank and capable of rotating by using an inclination axis as center; a stirring body configured at a rear part of the drum and including main blades in contact with washings; a driving unit enabling the drum and the stirring body to rotate at different rotating speeds; and a water supply mechanism part configured to splash water to a surface of the stirring body. The water supply mechanism part includes a first water storage part capable of moving between a position in water soaked in the outer tank and a position higher than the water and storing water when soaked in water of the outer tank, and a first outflow port capable of enabling water stored in the first water storage part to flow out to the surface of the stirring body at an upper position.

First claim

What is claimed is:

1. A drum washing machine, comprising:
an outer tank, configured in a shell;
a drum, configured in the outer tank and capable of rotating by using a horizontal axis or an inclination axis inclining relative to a horizontal direction as a center;
a rotating body, configured at a rear part of the drum and provided with a protruding part configured to be in contact with washings on a surface of the rotating body;
a driving part, configured to enable the drum and the rotating body to rotate at different rotating speeds; and
a water supply mechanism part, capable of splashing water to the surface of the rotating body;
wherein the water supply mechanism part comprises: a water storage part, configured on the rear part of the drum, and configured to move between a position of water soaked in the outer tank and a position higher than the water in the outer tank and store water when soaked in water of the outer tank; and an outflow port, configured on the water storage part, and configured to enable the water stored in the water storage part to flow out to the surface of the rotating body at an upper position;
wherein the protruding part extends radially from center of the rotating body to an outer circumference part of water soaked in the outer tank.

2. The drum washing machine according to claim 1 , wherein
the water storage part is configured to move through rotation of the drum.

3. The drum washing machine according to claim 2 , wherein
the water supply mechanism part comprises an intake port configured at the water storage part and configured to take water in the outer tank into the water storage part, and
the intake port is opened to an advancing direction side of the drum while rotating.

4. The drum washing machine according to claim 3 , wherein guide ribs capable of guiding water to the outflow port when the water flows out of the outflow port are configured in the water storage part.

5. The drum washing machine according to claim 2 , wherein
guide ribs capable of guiding water to the outflow port when the water flows out of the outflow port are configured in the water storage part.

6. The drum washing machine according to claim 1 , wherein
guide ribs capable of guiding water to the outflow port when the water flows out of the outflow port are configured in the water storage part.

7. The drum washing machine according to claim 1 , wherein
a recess part is formed in a back corresponding to the protrusion on the surface of the protruding part,
the water storage part comprises the recess part and moves through rotation of the rotating body, and
the outflow port is formed in the recess part.

8. The drum washing machine according to claim 1 , wherein
hollow baffles are configured on an inner circumferential surface of the drum,
the water storage part comprises the baffles and moves through rotation of the drum, and
at the baffles, the outflow port is configured at a position where water flowing out of the outflow port is splashed to the surface of the rotating body.
