Drum washing machine

Abstract

This washing machine is so constituted that the bottomed and cylindrical rotating drum 2 is disposed in a water tub 3 with its axial center inclined from the front side to the rear side. The internal circumferential wall of the rotating drum 2 is provided with agitating projections whose top parts 4a are formed into crest-shape cross sectional projections inclined from the axial direction of the rotating drum 2, in a plurality of positions. This constitution can lift the laundry, which is apt to be gathered in the lower position in the rear side by the rotation of the rotating drum 2, to a high position in the front side so as to improve the agitating effects of the laundry.

Description

technical field [0001] The invention relates to a drum-type washing machine in which a rotating drum is arranged in a water tub such that its rotating axis is inclined downward from the front to the rear. Background technique [0002] In a front-loading washing machine in which the rotating drum is installed in the water tub with its rotating shaft in a horizontal direction, by rotating the cylindrical rotating drum, the laundry put into the rotating drum is caught on the surface of the rotating drum. The protruding part on the wall of the inner cylinder is lifted by stirring the protruding objects, and the lifted laundry will fall down after reaching a certain height. In this way, the laundry is impacted and washed clean (the specific operation process Reference can be made to Japanese Patent Laying-Open No. Hei 09-215894, pages 2-6 and figure 1 ) [0003] As mentioned above, since the drum type washing machine mainly washes the laundry by means of impact washing, compare...

Problems solved by technology

[0004] However, when the rotary drum is tilted from the horizontal direction, the laundry thrown into the rotary drum will be biased towards the bottom side of the back of the rotary drum, so that the existing structure of agitating protrusions cannot correctly play the role of bringing the laundry. The problem of the effect of making it drop and performing impact washing

In addition, after the rotating drum is tilted, the washing liquid will also be concentrated on the back and bottom side of the rotating drum. If the existing structure of stirring protrusions is continued to be used, it will be difficult to make all the laundry soaked evenly in the state of less washing liquid. liquid problem
