Embodiment 1

[0020] figure 1 It is a longitudinal sectional view of the front-loading-type washing machine in Embodiment 1 of the present invention.

[0021] like figure 1 As shown, the inside of the washing machine body 51 of the front-loading washing machine in this embodiment at least includes: a water holding cylinder 52 arranged to shake freely; , and the motor 54 that is located at the back side outside of the water storage tube 52. The rotary drum 53 is driven by a motor 54 . On the inner side wall of the lower part of the water tank 52 , along the direction of the rotating shaft 63 of the rotary drum 53 , there is provided a concave drainage groove 76 , and a drainage outlet 71 is arranged in the concave drainage groove 76 .

[0022] In addition, the drum type washing machine of this embodiment has the following functions, that is, the control unit 74 controls the washing machine according to the set operation mode and control program. figure 1 The motor 54, water supply sys...

Embodiment 2

[0048] Combine below Figure 3A and Figure 3B A drum type washing machine according to Embodiment 2 of the present invention will be described.

[0049] Figure 3A It is a front sectional view of the structure at the drain tank of the drum type washing machine according to Embodiment 2 of the present invention, Figure 3B Yes Figure 3A partial perspective view of .

[0050] like Figure 3A and Figure 3B As shown, the difference between the front-loading washing machine of this embodiment and Embodiment 1 is that: the lower extending flange 82 extends from the side wall 77 of the water supply pipeline 75 side of the drain tank 76 toward the opposite side wall 77A, and The short side 83 of the drain tank 76 on the water supply line 75 side and the long side 84 on the side opposite to the water supply line 75 side of the drain tank 76 substantially constitute a V-shape (including the V-shape). Furthermore, it is different from the first embodiment in that a gap 85 is pr...

Abstract

A drum-type washing machine of the present invention comprises: a rotation drum; a water tank containing the aforementioned rotation drum, and tilting upward to face the front side along the direction of the rotational shaft a; a motor for driving the rotation drum to rotate; a water supply path connected to the water tank, and disposed at a side location farer away with respect to the central axis direction which is perpendicular to the center of the water tank; a drainage tank disposed below the water tank and showing a recess shape; and a drainage port disposed on the bottom of the drainage tank. An upper extension rib member and lower extension rib members are disposed on a side wall of the water supply path of the drainage tank. The upper extension rib member covers the drainage port. The lower extension rib members between the drainage port and the upper extension rib member cover the drainage port. The front end of the lower extension rib member protrudes more toward the side wall which is opposite to the side wall by the water supply path side of the drainage tank than the front end of the upper extension rib member does.

Description

field of invention [0001] The present invention relates to a drum-type washing machine for washing clothes and the like in a rotary drum. Background technique [0002] Some of the existing washing machines have a structure that can prevent the detergent thrown into the water tub from the detergent input part from flowing to the drain pipe through the drain outlet provided at the bottom of the water tub, thereby preventing the cleaning effect from being reduced. For an example of this, see Japanese Patent Laid-Open Publication No. 2007-111409. [0003] The following pass Figure 4 , Figure 5A as well as Figure 5B The configuration of the conventional washing machine described in the above patent publication will be described. [0004] Figure 4 is a longitudinal sectional view of an existing washing machine, Figure 5A is a cross-sectional view seen from the front for explaining the structure near the drain tank of this washing machine, Figure 5B Yes Figure 5A stere...
