Description

[Detailed description of the invention] The present invention is a drum-type washing machine in which the laundry drum is rotatable in either the left or right direction in the washing liquid tank, and the rotational axis of the laundry drum is set relative to the horizontal line. The present invention relates to a drum-type washing machine in which the vane plates provided upright inside the circumferential wall of the laundry drum are inclined with respect to the axis of rotation, and the conventional vane plates are provided parallel to the axis of rotation. Compared to horizontal rotating drum type washing machines, the internal laundry is compressed,
It is an object of the present invention to provide a high-efficiency drum-type washing machine in which the degree of relaxation is greatly increased and the efficiency of dirt removal is improved and the washing time is shortened.

To explain the present invention based on drawings showing embodiments thereof, as shown in Figs. In addition, a cylindrical laundry drum 2 with a bottom wall is rotatable in either the left or right direction while the longitudinal axis of the laundry drum 2 coincides with its own rotation line inside the laundry liquid tank 1. Set it up so that A large number of holes 5 for the circulation of washing liquid 6 are perforated in the trunk peripheral wall and bottom wall of the laundry drum 2, and a trunk peripheral surface blade plate of an appropriate width is provided upright inside the trunk peripheral wall of the laundry drum 2. 3, the washing drum is made to have a certain inclination as appropriate with respect to the axis of rotation of the laundry drum. In this embodiment, since the bottom surface is formed into a dish-like concave surface, a bottom blade plate 3' of an appropriate width is also provided on the inside of the bottom wall to increase the compression and agitation efficiency for the laundry that comes into contact with the bottom surface. It is also planned.

In such a washing machine, the washing liquid 6 is poured into the washing liquid tank 1 as shown in FIG. 1, the appropriate amount of laundry is put into the laundry drum 2, and then When rotating the laundry drum 2 in the direction, the axis of rotation of the laundry drum 2 is inclined with respect to the horizontal line, and the line of construction of the drum circumferential blade plate 3 is inclined with respect to the line of rotation, and Since the upper part of the vane plate 3 rotates at a more forward position, the laundry is automatically pushed toward the lower right corner of the bottom of the laundry drum 2 in FIG. The degree to which the laundry is compressed by being strongly pushed toward the corner by the drum is different from that of the conventional laundry drum, in which the axis of rotation of the laundry drum is horizontal and the blades on the body circumferential surface are parallel to the axis of rotation. It is much larger than those erected in the
The degree of contact between the washing liquid and the laundry tissue is strengthened, which naturally improves dirt removal efficiency and shortens washing time. Furthermore, when the laundry drum 2 is rotated in the direction of the dotted arrow in FIG.
As the laundry drum 2 shown in the figure is pushed up or flipped up into the upper right space of the body, the rotational position of the laundry can be changed and the degree of separation is enhanced, and the loosening rate of the laundry and the laundry as a whole are improved. This greatly contributes to improving the turbulent mixing rate of the washing machine, and from that point of view as well, washing efficiency can be naturally improved.

Therefore, if the washing drum 2 is made to alternately repeat the rotation in the direction of the solid line arrow and the direction of the dotted line arrow in FIG. 1 at an appropriate time period, the degree of mixing of the entire laundry will be increased. Of course, there is no risk of uneven washing caused by partial over- or under-washing, and the laundry is compressed with much stronger compression force than in conventional washing machines (i.e. The washing effect) and the relaxing force are alternately applied, which can significantly contribute to improving washing efficiency.

Furthermore, in such a washing machine, as shown in FIG. 1, the opening/closing door 7 for loading and unloading the laundry in the laundry drum 2 is inclined with respect to the floor surface 4, and the axis of the laundry drum 2 is also parallel to the floor. Since it is inclined with respect to the surface 4, there is no need to bend down or stretch when loading and unloading laundry or looking into the inside of the laundry drum 2, making these operations very easy. become. Furthermore, since it is sufficient to apply the washing liquid 6 only to the lower right corner of the bottom surface of the laundry drum 2, compared to a conventional washing machine in which the laundry drum rotates around a horizontal axis of rotation. The effect of saving the amount of washing liquid is also great.

The body circumferential blade plate 3 is usually a band-shaped plate with a constant width, and as shown by the chain line in FIG. It is also possible to use an irregularly shaped band-like plate whose radius of curvature is larger than the radius of curvature on the plane of the portion in contact with the peripheral wall of the laundry drum 2, that is, the width of the central portion is larger than that of both ends. This method may be employed as needed to further increase the degree of compression of the laundry as described above.

In the embodiment shown in FIGS. 3 and 4, the degree of inclination of the axis of rotation of the laundry drum 2 with respect to the horizontal line is somewhat reduced, while the inclination of the blade plate 3 with respect to the axis of rotation is The difference is that the degree of pressure is somewhat increased, but even in this case, the laundry is strongly compressed to make the contact between the laundry tissue and the washing liquid stronger, and so on. The same effect as described above can be achieved in improving the washing efficiency.

Note that the drawing numbers 8, 9, 10, and 11 are V for transmitting the rotational force from the motor (not shown).
The belt, pulley, rotation transmission shaft of the laundry drum, and washing machine exterior panel are shown, respectively.

Furthermore, the washing machine according to the present invention can of course perform the washing operation, dehydration operation, or starching operation following the washing operation in the same way as conventional washing machines, and also performs the above-mentioned washing operation in the rinsing operation and the starching operation. As in the operation, the contact between the washing water or starch water and the laundry tissue increases, resulting in high efficiency. It goes without saying that the washing machine of the present invention is also useful for dry cleaning.
