Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric washing machine that utilizes the rotation of stirring blades to circulate washing water and has a device for collecting lint in the washing water. be.

[Conventional technology]

Conventional lint collection devices for washing machines use the rotation of blades formed on the bottom of the stirring blade to circulate the washing water, and the other uses a separate pump to circulate the washing water. A filter was installed in November to collect lint.

[Invention or problem to be solved]

There are two methods of lint collecting devices using stirring blades. One is that the stirring blade has a hollow cylindrical body in the center, and around the outside there are multiple lint collection devices for stirring the clothes. wings,
Furthermore, multiple blades are integrally formed on the back side of the bottom. A plurality of through holes are formed in the wall of the body, and as the stirring blade rotates, washing water in the blades on the back side of the bottom is pushed out toward the outer circumference of the stirring blade by centrifugal force. At that time, the water inside the body is sucked in, and to compensate for this, the water in the washing tub is
When water flows into the stirring blade body and lint generated from clothing also flows in, it is collected by a filter installed in the stirring blade body. Another type is one in which water pushed out in the outer circumferential direction by the rotation of the stirring blade is provided with a water channel inside the washing tub from the bottom to the top, and lint is collected by a filter provided at the top. In either configuration, in order to efficiently collect lint waste at low water levels, the problem is that the lint collection efficiency decreases due to the influence of holes in the body and the reduction in the amount of washing water circulating due to water head loss. There was.

[Means to solve the problem]

The present invention provides a lint collection device that solves the conventional problems and improves the lint collection efficiency. In addition, a stirring blade with blades formed on the back side of the bottom [a filter member is installed in a part of the washing tub adjacent to this], and a handle is integrated with the filter at a height above approximately the center of the inside of the washing tub wall. The filter is further provided with a fixing device for fixing the filter part, and this configuration improves the collection efficiency of thread waste and improves operability.

[Effect]

A 1i stirring blade is attached to the bottom of the washing tub, and a filter member is provided in a part of the washing tub near the stirring blade with blades formed on the back side of the bottom. The washing water, that is, the lint, can be collected immediately, and there is less water head loss due to the water level, which increases the collection efficiency.2. Next, the handle is attached to the filter member at a height approximately at the center of the inside of the washing tub wall. The integrated construction makes it easy to clean without having to reach the bottom of the washing tub, which improves operability when attaching and detaching.

Also, providing a fixture for fixing the filter member means
It is possible to prevent the filter from getting caught during attachment and detachment, and to improve operability during installation.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the attached f=j drawings.

In Figure 1, "" is an outer tank that receives washing water, and 2 is an outer tank 1.
It is a washing and dehydration tank installed inside the center, with stirring blades 3 at the bottom and washing water circulating on the side walls.
A washing and dehydration tank hole 4 is provided with a large number of small holes for draining water during dehydration. Although not shown below, the stirring blade 3 is used during washing.
During spin-drying, a motor for rotating the washing and dehydrating tank 2, a mechanism for transmitting the drive of the motor (a mechanical case for the bell 1, a pulley, a speed reduction mechanism, etc.), etc. are arranged at the bottom of the outer tank. There is.

Next, regarding conventional lint collection, there are two methods: one is to circulate the washing water using vanes 5 formed on the F side of the stirring blade 3, and the other is to circulate the washing water using a separate pump. is installed to collect the thread waste.

When using a pump here, a motor to drive the pump and pipes as a circulation path are required, so
It is expensive in terms of price. In addition, the method of circulating washing water using the blades 5 formed on the lower surface of the stirring blade 3 involves installing a water channel from the bottom to the top inside the washing and dehydrating tank 1, and removing lint with a mesh filter at one end. Generally speaking, if there is a difference in the distance between a portion of the filter at the upper end, that is, the discharge port, and the water level surface, there is a drawback that collection efficiency deteriorates due to water head loss, especially as the water level becomes lower.

Here, as shown in FIG. 1, FIG. 2, and FIG. 3, the back blade 5 of the stirring blade 3 is buried in the bottom of the washing and dehydrating tank 2, and the washing and dehydrating tank 2 is connected to the outer periphery of the stirring blade 3. The gap is small and prevents leakage of circulating water. A lint collecting device 8 is installed on the inner wall of the washing and dehydrating tank 2, and is fixed to the filter case 8a or the washing and dehydrating tank 2 with a screw. It is configured as a gift. Next, as shown in FIG. 4, the filter cover 8b has a handle 8C for attaching and detaching and four parts of the filter cover]2. Filter 9. filter fixture 9a,
It has an inlet ID 11 of washing water and an outlet ID 10.

To explain the operation in the configuration L, as the stirring blade 3 rotates, the washing water around the stirring blade back blade 5 is pushed out toward the outer circumference by centrifugal force. This water passes from inside the washing/dehydration tank 2 through the washing/dehydration tank hole 4 as shown by the arrow in FIG.
It flows into the outer tank 1 and flows into the filter via Francillo.
11 and the discharge rl 12, and returns to the inside of the washing/dehydration tank 2. The thread waste contained in this water removal is collected by the filter 9.

Here, the advantage of the configuration described in 1-1 is that the filter 9 is provided in a part of the bottom of the washing/dehydrating tank 2 near the stirring blade 3 because the filter outlet 110 is under the water surface. , water head loss or less. In addition, the centrifugal force of stirring blades (3) pushes out water in the same direction as the outer circumference, reducing resistance and leakage from waterways, increasing collection efficiency.
Jr always gets better.

Next, by placing the handle 8c at a height above approximately the center of the inner wall of the washing and dehydrating tub 2 and comprising the filter 9 and the body, when cleaning the filter 9, the user can easily reach the bottom of the washing and dehydrating tub 2. The filter cover 8b can be easily attached and detached without having to insert the filter cover 8b.

In addition, by installing the filter cover recess 12, it is possible to easily insert a finger when operating the handle 8c, improving attaching and detaching properties, and by providing a fixing device 9a on the filter 9, the filter cover 8) can be easily inserted. Filter case 8
Since the strain of the filter 9 is weak when it is removed, the filter 9 and the filter cover 8b are fixed to prevent them from falling down, thereby preventing them from getting caught.

Another advantage is that by installing the lint collecting device 8 in a convex shape on the inner wall of the washing and dewatering tank 2, it has the effect of promoting the replacement of cloth during washing, thereby improving washing performance, especially uneven washing. I was able to do it.

The lint collecting device 8 will be explained in more detail.

As shown in FIG. 5, the filter case 8a is attached to the washing and dehydrating tub 2 with screws 8d.

The washing and dehydrating tank 2 is provided with four parts in order to attach the filter case 8a. Two pieces of Neshi 8d are used.

The illustration shows the -1- side. A boss 8e is provided on the filter case 8a for screwing in the screw 8d.

A filter cover 8b is attached to a filter case 8a.

Fit the lower part of the filter cover 8b into the four parts provided at the lower part of the filter case 8a, and
The side is latched to the filter part 8a with a handle 8c.

The handle 8 is rotatably supported by the filter cover 8 with a support shaft 8f, and the claw portion is pushed in the direction by a spring 8g. The claw part of the handle 8 fits into the engagement hole 8 of the filter cover 8
By engaging with h, the upper side of the filter cover 8 is attached to the filter case 8a.

A filter 9 provided on the back surface of the filter cover 8 has an opening of the filter 9 attached to the lower part of the filter cover sb. The filter 9 is attached so that the opening 11 is located at the filter inlet D11 of the filter cover 8. The rear part of this filter 9 is closed, and a filter fixture 9a provided at the rear part is hooked onto a hook provided on the back surface of the filter cover 8.

Although the above embodiment has been described with respect to a fully automatic washing machine that uses a washing and dehydrating tub, the same applies to a two-tank type washing machine that has a washing tub that also serves as a dehydrating tub. In a two-tub washing machine, it is necessary to form a water channel at the bottom of the washing tub to guide water to the blade side.

〔Effect of the invention〕

As described above, the lint collecting device of the present invention has good washing water circulation efficiency, that is, lint collecting efficiency, by installing the filter in a part of the bottom of the washing tub in close proximity to the agitating blade, and also has a handle. By providing the filter on more than half of the inside wall of the washing tub, it is easier to operate when installing and removing the filter.In addition, providing a fixing device on a part of the filter prevents the filter from falling and getting caught during installation, making it easier to operate. It is aimed at the direction of sexuality.

Furthermore, by using the protrusions in conjunction with the protrusions during washing, the cleaning performance is also improved as the number of cloth changes increases.
