Abstract

PURPOSE:To make washing ability excellent even if a large amount of clothes exist in a washing receptacle, by a method wherein a pulsator of which the whole shape is conical or frustoconical, is mounted on the interior of the washing receptacle, in the state of an upward projection. CONSTITUTION:A pulsator 2 for agitating washing water 3 is mounted at the central part of the inner bottom in a washing receptacle 1. At this time, the pulsator 2 of which the whole is formed in the shape of a cone or of a frustoconical shape, is mounted on the interior of the washing receptacle 1, in the state of an upward projection. As the result of it, the washing ability of the title machine is made excellent even if a large amount of clothes exist in the washing receptacle.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to so-called washing machines, and in particular, by making the shape of a pulsator for stirring washing water into a conical or truncated conical shape. This invention relates to a washing machine that is designed to be more effective.

[Prior Art] Until now, washing machines in general have simply had a flat plate-shaped pulsator equipped with stirring blades attached to the bottom of the washing tub. Regarding this type of technology, for example, Japanese Patent Application Laid-Open No. 55-32548 can be mentioned, but in this case, the shape of the pulsator is not fundamentally changed, but the blades are simply added. It has become a thing.

[Problems to be Solved by the Invention] Therefore, in conventional washing machines, no particular consideration has been given to how to efficiently transmit the rotational force of the pulsator to the washing water, and the cleaning effect has not been improved. There are some problems with this. Particularly when a large amount of laundry is present in the washing tub, the laundry is not easily rotated by the rotation of the pulsator, and the cleaning power is inevitably reduced.

An object of the present invention is to provide a washing machine that has excellent cleaning ability even when a large amount of laundry is present in the washing tub. [Means for Solving the Problems] This is achieved by attaching a conical or truncated conical pulsator to the center of the inner bottom of the washing tub, with the pulsator projecting upwards inside the washing tub.

[Function] When a pulsator whose overall shape is a conical or truncated cone is installed at the center of the inner bottom of the washing tub with the pulsator projecting upward in the washing tub, the pulsator As a result of the large surface area, which agitates the washing water existing not only near the inner bottom of the washing tub, but also from the inner bottom through the center to the upper part, the washing water becomes a strong swirling turbulent flow. This is where the laundry (clothing) is washed. Even if a large amount of laundry is present in the washing tub, the pulsator forcibly rotates the laundry by wrapping the laundry around the pulsator itself, so a reduction in cleaning power can be avoided. .

[Example] The present invention will be explained below with reference to FIGS. 1 to 3.

First, the main structure of a washing machine according to the present invention will be described. FIG. 1 is a cross-sectional view of a washing tub and a pulsator attached to the center of the inner bottom thereof. As shown in the figure, the pulsator 2 has a conical overall shape and is attached to the center of the inner bottom of the washing tub. If the pulsator 2 is rotated with the washing water 3 around it, the pulsator 2 will agitate the washing water 3 using its large surface area. As a result, the laundry floating in the washing water 3 is also transferred to the pulsator 2.
As a result of the forcible rotation of the laundry, even if there is a large amount of laundry, the laundry can be washed with great cleaning power.

Now, if the pulsator 2 is explained in detail, the overall shape of the pulsator itself may be cylindrical, but a conical shape or a truncated conical shape is suitable.

Furthermore, it is desirable that the surface shape of the pulsator be in harmony with the overall shape of the inside of the washing tub, so that the flow of washing water is appropriately turbulent and spiral. FIGS. 2 and 8 show a side view and a plane view, respectively, of an example of a pulsator according to the present invention. Its surface shape resembles a half-opened bat umbrella, but as long as it does not damage the laundry,
Various other surface shapes are also possible.

[Effects of the Invention] As explained above, according to the present invention, even when a large amount of laundry is present in the washing tub, the laundry is forced by the conical or truncated conical pulsator. Since the washing machine can be agitated, a washing machine with excellent cleaning ability can be obtained.
