Description

[Detailed description of the invention] The present invention consists of a washing/dehydrating tank having an internal agitating blade that performs periodic and repetitive rotational motion with the center axis in the substantially vertical direction, and an outer tank enclosing the washing/dehydrating tank. This relates to an agitating washing machine equipped with an agitating type washing machine, in which the water in the tank is circulated by the periodic repeated rotational movement of an agitating blade, and the lint contained in the water is captured by a lint filter installed inside the agitating blade. The slit-shaped hole in the cylinder at the top of the blade prevents it from being blocked by clothes during washing, which prevents a drop in water circulation and prevents clothes from getting tangled in the stirring blade, making it easier to wash. The purpose is to reduce unevenness and improve cleaning performance.

There are two main types of water circulation methods used in conventional agitator washing machines.

One method is to install a circulation pump at the bottom of the washing and dehydrating tank to circulate water, and the other method is to circulate water using the stirring motion of stirring blades.

As stirring blade methods, methods in which the stirring blade is moved up and down, and methods in which the stirring blade is repeatedly rotated are known.

However, in general, stirring blade systems, especially those in which stirring blades are rotated repeatedly, have been put into practical use and are still in use today.

In devices that utilize the repeated rotational motion of the stirring blades, the method for capturing lint is to provide holes on the outer circumferential surface of the stirring blades through which water flows, and to install a lint filter inside the stirring blades. Since it is common for a large amount of clothing to be placed in the washing and dehydrating tank, the holes provided on the outer circumferential surface of the stirring blades are blocked by the clothing, and as a result, the amount of water circulated is reduced. As the amount decreases, clothes get entangled in the agitating blades, resulting in a decrease in cleaning performance, and clothes near the cylindrical part of the agitating blades are not agitated, resulting in insufficient cleaning performance.

The present invention solves the above-mentioned conventional drawbacks, and the following:
One embodiment will be described in detail based on the accompanying drawings.

In the figure, 1 is an outer frame, 2 is an outer tank, and 3 is a washing and dewatering tank enclosed by the outer tank 2. This tank 3 is fixed to one end of a dehydrating shaft 4.

Reference numeral 5 denotes a substantially conical agitating blade having clothes agitating blades 6 on its circumferential surface for agitating the clothes, which is fixed in an appropriate manner to one end of a washing shaft 7 located in a substantially vertical direction. axis 7
and the dehydration shaft 4 are arranged coaxially.

According to the drawing, the stirring blade 5 is rounded with a radius of curvature on its circumferential surface, but this is purposely called a substantially conical shape, and the upper end surface is flat, but this is also a substantially conical shape. considered as part of.

The upper part of the stirring blade 5 has a cylindrical tube part 5a,
A slit-shaped 68 is provided on the outer circumferential wall, and a small blade 9 is provided along this 68.

A lint filter 10 is detachably arranged in the cylindrical portion 5a of the stirring blade 5.

Further, an outlet 11 is provided at the lower part of the cylindrical portion 5a of the stirring blade 5, and a slit-shaped 68 provided on the outer periphery of the cylindrical portion 5a connects the cylindrical portion 5a.
The ice that has entered inside a passes through a lint filter 10 and flows out from an outlet 11.

12 is a bearing portion for pivotally supporting the washing shaft 7 and the dehydration shaft 4;
The washing shaft 7 and the dewatering shaft 4 are connected to a motor shaft 14 of a motor 13 via the clutch mechanism 12.

15 is a fixture for supporting the motor 13, and 16 is a vibration isolating mechanism, one end of which is suspended from the outer frame 1, and the other end of which suspends and holds the outer tank 2.

The operation in the above configuration will be explained.

During washing, when the motor 13 is repeatedly rotated clockwise and counterclockwise using a CR timer that uses the charging and discharging time of a capacitor, a time control method using a cam contact, etc., the movement of the motor shaft 14 causes the clutch mechanism 12 to rotate. Washing shaft 7 through
The agitating blade 5 mounted on the washing shaft 7 performs an agitating motion by repeating left and right rotations to wash the clothes in the washing and dehydrating tub.

When the stirring blade 5 is stationary, the water surface in the cylindrical portion 5a exists at a position corresponding to the water surface in the washing and dehydrating tank 3.

Next, in the washing process, water that has entered the stirring blade 5 passes through the lint filter 10 to the outlet 1 of the stirring blade 5 due to the centrifugal force caused by the clockwise or counterclockwise rotation of the stirring blade 5.
1 and flows out along the substantially conical part of the stirring blade.

Then, the water level in the cylindrical part 5a falls, and the water in the upper part of the washing/dehydration tank 3 flows into the cylindrical part 5a through the 68 provided above the stirring blade 5.

The above movement of water occurs when the stirring blade 5 rotates both left and right, and the water in the upper part of the outer tank 2 passes through the lift filter 10 in the stirring blade 5 and flows out to the lower part of the washing and dewatering tank 3. is circulated, and lint and the like contained in the water are captured by a lint filter 10.

Here, by providing the small blades 9 along the slit-like sixty-eight, even if the cloth adheres to the stirring blade 5 when water is sucked into the sixty-eight, a gap is created between the sixty-eight and the cloth. , it won't block 68.

Moreover, since the small blades 9 are provided in the vertical direction on the cylindrical part of the stirring blade 5, they act as stirring blades by the stirring movement,
An effect is created to push away the cloth attached to the stirring blade 5, and as a result, it is possible to reliably prevent the cloth from blocking the 68, and to prevent the amount of water sucked from decreasing.

Also, when the stirring blades 5 rotate left and right, the small blades 9 apply a force to the cloth in a circumferential direction from the center of the washing/dehydration tank 3, but this force is not applied to the cloth. , since the fabric acts to separate from the stirring blade 5, preventing the cloth from getting entangled with the stirring blade 5.

In addition, the force that pushes the cloth away is generated by the left and right rotation of the small blades 9, which also has a cleaning effect on the cloth near the cylindrical part of the stirring blade 5, and the movement of the small blades due to this stirring movement. Since it is small and makes small movements, it is possible to wash small parts of the cloth, reducing uneven washing and ensuring even washing.

As described above, according to the agitation type washing machine of the present invention, during washing,
Even if clothing covers the slit-shaped hole provided at the top of the stirring blade,
This hole does not get blocked, which prevents a decrease in water circulation, which has a good lint capture rate, and reduces the adhesion of lint to clothing, and the small blades prevent uneven washing. The cleaning performance is improved with less dust, and the excellent effects of being able to suppress the cloth from getting stuck on the stirring blades have been achieved.
