Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a washing machine (a stirring blade disposed on the bottom of the tank is rotated back and forth to stir the items to be washed in the washing tank).

This invention relates to an agitation type washer that shakes to make washing easier.

A conventional stirring type washing machine (although not publicly known) was constructed as shown in FIG.

That is, in the figure, (1) is the outer box of the washing machine, (2) is the washing tank that stores water and washed items fixed inside the outer box (1), and (3) is the bottom center of the washing tank (2). The main shaft (4) is watertightly and rotatably inserted into the main shaft, and the main shaft (4) drives the continuous rotation of the motor (5) (hereinafter referred to as the motor) through the motor pulley (6), deceleration pulley (7), and belt (8). A conversion mechanism (9) is a link mechanism that converts the main shaft (3) into reciprocating rotational motion within a predetermined angular range of approximately 120°; Q2 is a column whose diameter increases downward in a tapered manner and is fixed to the column (9), and is arranged radially at a pitch of 90° to this column (9) so that the protruding distance from the axis of the main column (9) is downward. It gradually became larger. Thin plate-like wings.

aυ is a stirring blade in which 20 blades are arranged radially at 90° pitch on four main pillars (9).

In the above configuration, first, the items to be washed, water and detergent are placed in the washing tank (2), and when the power is turned on, the motor (5)
rotates continuously in the -force direction, and the driving force of the motor (5) is transmitted to the conversion mechanism (9) after being decelerated by the morph pre- (6), belt (8), and deceleration brie (force);
The link mechanism of this conversion mechanism (4) converts the rotational motion into a reciprocating rotational motion of approximately 120° angle at a predetermined period 8
This reciprocating rotational movement is then stirred by the main shaft (3).
．． (11), each blade α2 rotates reciprocatingly at a predetermined period within an angular range of about 120°, stirring the object to be washed, water, and detergent. The blades O2 extend radially to the main column (9), and the protruding distance from the axis of the column (9) gradually increases downward, so the items to be washed and the detergent liquid are transferred to the blades (I3).
The force exerted by the washing machine gradually increases from the top to the bottom, and the force exerted by the object to be washed and the detergent liquid to move in the radial direction also increases from the bottom. Therefore, a pressure difference occurs from the top to the bottom.

The items to be washed and the detergent liquid from above are sucked in and moved downward around the main pillar (9) between the blades a2 and 021 while swinging downward. The items to be washed and the detergent liquid at the bottom are moved to the side wall of the washing tank (2) while being oscillated, and are moved upward along the side wall. Therefore, the items and the detergent solution are rotated slowly in the vertical direction while being shaken and stirred, the items to be washed above move downwards, and the items to be washed below move upwards, and the items to be washed are washed.

Since the blade 0 side has a large downward protrusion distance, the items to be washed located at the bottom of the washing tank are those located at the top (
The cleaning effect is high because the object is oscillated and stirred more vigorously than the object (cleaning is mainly performed when the object to be washed is located below.However, because the object to be washed moves from the top to the bottom at a slow speed) However, if you do not take enough time, you will not be able to clean all the items evenly.

If the shape of the blades is made the same size as the top and bottom and the items to be washed above are vigorously shaken and stirred, the items to be washed can be cleaned evenly in a short time, but the load resistance applied to the stirring blades will increase. wings and main shaft.

The strength of the mechanical parts such as the conversion mechanism must be increased,
In addition, it is necessary to increase the motor capacity, which has the disadvantage of increasing costs.

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional technology, and uses a stirring blade that rotates back and forth.

゛ In an agitating type washer that shakes and agitates the items to be washed, the shape of the stirring blades effectively shakes and stirs the items to be washed, and the purpose is to uniformly wash the items to be washed in a short time.

Hereinafter, nine embodiments of the present invention will be described with reference to the drawings.

In FIGS. 2 and 3, (1) to (9) are exactly the same as the conventional device described above.

011 is a thin plate-like main blade whose protrusion distance from the axis of the support (9) gradually increases downward from the top to the bottom of the support (9), and (2) is the approximate center height of the support (9). Thin plate-shaped auxiliary blades whose protruding distance from the axis of the support (9) gradually increases downward from the position, @ is three of the above main blades at a pitch of 120°, and three auxiliary blades each. The stirring blades are located in the middle of the main blades and are arranged radially at a pitch of 120°.

In the stirring type washing machine configured as described above, the items to be washed and the detergent liquid are stirred by the stirring blade (c), but the pressure difference generated from the top to the bottom by the main blade Q11,
Due to the pressure difference generated in the lower part of the tank by the auxiliary blades (C), the objects to be washed and the detergent solution flow as shown in Figure 3 (arrow). is vigorously oscillated and stirred by the main blade CID and the auxiliary impeller (C), and the items to be washed are sufficiently washed, and the items to be washed and the detergent liquid in the lower part are washed by the water flow generated by the agitation of the main blade QD and the auxiliary blade (C). Due to the movement, the items to be washed are moved towards the side wall of the washing tub (2) and pushed upward along the side wall. The items to be washed in the upper part are moved by the pillars (9) as the items to be washed in the lower part are moved.
), the items to be washed are moved upward along the peripheral wall of the main blade C21), and the items to be washed are moved downward by rocking and agitation by the main blade C21), and are quickly sucked downward. It is vigorously shaken and stirred by the blades (c) and moves upward again.

In this way, the items to be washed are vigorously shaken and agitated while moving up and down, so that the items to be washed can be washed evenly in a short period of time.

In the above embodiment, the protruding distance of the main blade and the auxiliary blade is appropriately designed depending on the depth and diameter of the washing tank, and the washing tank is not limited to a rectangular shape, but even if it has a circular cross section, the effect will not be affected. The same can be obtained. Furthermore, the means for obtaining reciprocating rotational motion is not limited to link mechanisms (
It may also be based on forward/reverse rotation control of the motor. Furthermore, the number of blades is not limited to the above embodiment.

As described above, in the present invention, by using a simple structure in which the stirring blades are alternately arranged with blades that protrude downward from above and blades that protrude only from the lower part, cleaning can be achieved with less unevenness and in a shorter time. It is possible to provide a low-cost agitating type washing machine that can perform washing quickly and has a low-capacity motor.
