Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and particularly relates to a wave wheel structure of a washing machine. Background Art

[0002] With the development of washing machine automation technology, fully automatic washing machines have gradually entered thousands of households. Fully automatic washing machines are mainly divided into two types: wave wheel washing machines and drum washing machines. Among them, most of the residual lint and other dirt after washing in a wave wheel washing machine gather in the filter box and need to be manually cleaned. If not cleaned in time or forgotten to be cleaned, the dirt is likely to breed bacteria and rot and stink in the humid and shaded environment inside the washing machine, increasing the labor intensity while affecting the safety of clothes and human health and reducing the consumer experience. To solve this problem, some R & D personnel have designed a self-cleaning filter wave wheel. However, the newly designed self-cleaning filter wave wheel still has some deficiencies. For example, the filter holes of the wave wheel are prone to blockage, affecting the water flow rate and circulation speed of the washing water, and the filtering and purification effect of the washing water is not ideal. For another example, the compatibility with the original washing barrel is not considered enough, and it cannot be directly applied to the existing washing barrel. To achieve the functions of filtering the washing water of the wave wheel and self-cleaning the dirt, it is necessary to redesign and manufacture a matching washing barrel, which will greatly increase the renewal cost of the washing machine. Summary of the Invention

[0003] In view of the above situation, the present invention provides a wave wheel structure of a washing machine, which improves the compatibility of the wave wheel with the existing washing barrel on the premise of realizing the functions of wave wheel filtering and self-cleaning.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A wave wheel structure of a washing machine includes a wave wheel panel and a wave wheel back plate. The wave wheel panel and the wave wheel back plate are buckled with each other to form a hollow wave wheel inner cavity. A plurality of wave wheel ridges are annularly arranged on the front surface of the wave wheel panel. The back surface of the wave wheel ridge corresponds to a process groove. A partition board is arranged in each process groove. The plurality of partition boards correspondingly divide the wave wheel inner cavity into a plurality of independent water guiding chambers. An inlet is opened at the center of the wave wheel panel and is communicated with each water guiding chamber. A number of filter holes for discharging water are opened on each wave wheel ridge. A raised annular guide plate is fixedly arranged above the wave wheel back plate. The annular guide plate is coaxially placed in the inlet. A wave wheel shaft mounting hole for connecting the wave wheel shaft is fixedly arranged at the center of the annular guide plate. A plurality of sewage discharge ports for discharging filtered dirt are annularly arranged on the circumference of the wave wheel back plate.

[0006] Further, a one-way valve flap for preventing the washing water from flowing back from the water guiding chamber to the inlet is arranged between the inlet and each water guiding chamber. The structure of the one-way valve flap adopts the existing technology and will not be elaborated here.

[0007] Further, the annular flow guide plate is in the shape of an impeller, and a spline sleeve for mating and connecting with the agitator shaft is fixedly installed in the agitator shaft mounting hole. The spline sleeve can be integrally cast with the annular flow guide plate or can be a separate fitting fixedly assembled in the agitator shaft mounting hole.

[0008] Further, a guide plate corresponding to each sewage outlet is provided on the back surface of the agitator panel, and the sewage outlets are preferably arranged on both sides of the partition plate.

[0009] Further, a first sealing rib and a second sealing rib respectively corresponding to and buckling with the partition plate and the guide plate are also fixedly installed on the agitator back plate. When the agitator panel and the agitator back plate are buckled, each partition plate is hermetically buckled with each first sealing rib, and each guide plate is hermetically buckled with each second sealing rib.

[0010] Further, a sealing buckling groove is provided in a matching manner on the circumferential edges of the agitator panel and the agitator back plate, so that the edges of the agitator panel and the agitator back plate can be hermetically buckled well.

[0011] Further, the agitator panel and the agitator back plate are fixedly connected by screws, and a plurality of connecting screw holes are correspondingly provided on the agitator panel and the agitator back plate. In order to strengthen the firmness of the connecting screw holes, columnar reinforcing ribs are preferably provided around each connecting screw hole.

[0012] Preferably, four agitator ridges are preferably provided on the agitator panel, and the four agitator ridges are arranged in a cross shape. Of course, the number of agitator ridges can also be three, five, six, etc. No matter how many agitator ridges there are, they should be arranged at equal angles in a ring shape.

[0013] The present invention also includes other components that enable it to be used normally, which are all conventional means in the art. In addition, devices or components not defined in the present invention, such as one-way valve flaps, agitator shafts, etc., all adopt the prior art in the art.

[0014] The beneficial effects of the present invention are as follows:

[0015] The agitator structure belongs to a self-cleaning and filtering agitator, which has the functions of filtering and purifying laundry water and self-cleaning residual dirt. It can cancel the position for installing a filter box in the existing laundry tub, increase the laundry space in the laundry tub, and improve the circulation speed of the laundry water and the filtering and purifying effect of the laundry water. At the same time, the agitator can be directly installed in the original laundry tub. Without changing the structure of the original laundry tub, the agitator can realize the functions of filtering laundry water and self-cleaning dirt, improving the compatibility and versatility of the agitator with the original laundry tub, and greatly saving the renewal cost of the washing machine.

[0025] Embodiment

[0026] As Figures 1-6 shown, a agitator structure of a washing machine includes an agitator panel 1 and an agitator back plate 2. The agitator panel and the agitator back plate are mutually buckled to form a hollow agitator inner cavity. A plurality of agitator convex ribs 3 are annularly arranged on the front surface of the agitator panel. The back surfaces of the agitator convex ribs correspond to process grooves. Each process groove is provided with a partition board 4. The plurality of partition boards correspondingly divide the agitator inner cavity into a plurality of independent water guide chambers. A water inlet 5 communicating with each water guide chamber is opened at the center of the agitator panel. A number of filter holes 6 for discharging water are opened on each agitator convex rib. An upwardly convex annular guide plate 7 is fixedly provided above the agitator back plate. The annular guide plate is coaxially placed in the water inlet. A agitator shaft mounting hole 16 for connecting the agitator shaft is fixedly provided at the center of the annular guide plate. A plurality of drain ports 8 for discharging filtered dirt are annularly arranged on the circumference of the agitator back plate.

[0027] A one-way valve flap 9 for preventing the laundry water from flowing back from the water guide chamber to the water inlet is arranged between the water inlet and each water guide chamber, and the laundry water can only flow into each water guide chamber from the water inlet through the one-way valve flap.

[0028] The annular guide plate is in the shape of an impeller, and a spline sleeve 10 made of aluminum for cooperating with the agitator shaft is fixedly arranged in the agitator shaft mounting hole, and a locking set screw for pressing tightly against the agitator shaft is arranged on the side wall of the spline sleeve.

[0029] A guide plate 11 corresponding to each sewage outlet is arranged on the back of the agitator panel, the sewage outlet is in a U shape, and is divided into two halves by a partition plate and a second sealing rib.

[0030] A first sealing rib 12 and a second sealing rib 13 corresponding to the partition plate and the guide plate are fixedly arranged on the agitator back plate, and after being buckled, each water guide chamber and each sewage outlet have relatively good water guiding functions.

[0031] Sealing buckling grooves 14 are arranged in a matching manner on the circumferential edges of the agitator panel and the agitator back plate. When the agitator panel and the agitator back plate are buckled, the water inlet in the agitator cavity has relatively good water absorption function.

[0032] The agitator panel and the agitator back plate are fixedly connected by screws, and a plurality of connecting screw holes 15 are correspondingly arranged on the agitator panel and the agitator back plate.

[0033] Four fan-shaped agitator ridges are arranged in a cross shape on the agitator panel. Correspondingly, a vertical partition plate is fixedly arranged in the middle of each of the four process grooves. Filter holes are arranged on the outer side and the upper side edge of the agitator ridge far away from the water inlet.

[0034] The working principle of the present invention is as follows:

[0035] During laundry, the agitator rotates, and the laundry water in the laundry tub is driven to rotate by the agitator ridges and the annular guide plate. The laundry water at the water inlet of the agitator enters each water guide chamber in the agitator cavity through the one-way valve flap in a swirling manner, and then under the action of the centrifugal force of the agitator rotation, it is thrown out from each filter hole and returns to the laundry tub. The dirt such as lint in the laundry water is filtered and left in the process grooves on the back of the agitator ridges. In this way, the cycle completes the filtering and purifying function of the agitator on the laundry water. After the laundry is finished, when draining, the laundry water in the laundry tub flows through the water inlet and the filter holes of the agitator respectively, and at the same time, it discharges the lint and dirt remaining in the process grooves below the filter holes together, thereby realizing the reverse flushing and self-cleaning function of the filter holes of the agitator.

[0036] The technical solution of the present invention is not limited to the limitations of the above specific embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. Any technical transformation made within the spirit and principle of the present invention falls within the protection scope of the present invention.
