The washing machine is a clean electrical appliance that uses electricity to wash clothes. With the acceleration of the pace of life and people's high requirements for life comfort, the washing machine has become an indispensable household appliance in people's daily life. Taking the pulsator washing machine as an example, the pulsator washing machine relies on the friction with the clothes during the forward and reverse rotation of the motor to drive the pulsator to wash the clothes. However, in the actual washing process of this washing method, there are single water flow, low cleaning degree, and clothing. Serious entanglement and other problems have greatly affected the user experience.

In order to solve the above-mentioned problems of the pulsator washing machine, in the prior art, a water spout is usually provided on the wheel disc of the pulsator, and a water-repellent rib is arranged under the wheel disc.

Although the above technical solution solves the problems of single water flow and serious entanglement of clothes to a certain extent, it also inevitably has the following defects. Since the direction of the centrifugal force generated by the water repellent is distributed along the radial direction of the wheel disc, during the rotation of the water repellent bar, most of the washing water is thrown out along the radial direction of the wheel disc instead of directly leading to the spray water. This greatly reduces the jetting strength of the water flow, reducing the washing efficiency and washing effect. That is to say, the existing pulsator has the problems of low washing efficiency and poor washing and spraying effect.

Accordingly, there is a need in the art for a new impeller assembly to solve the above problems.

First, referring to FIGS. 1 to 4 , the pulsator assembly of the present invention will be described. Wherein, Figure 1 is a schematic structural diagram of a pulsator assembly of the present invention; Figure 2 is a schematic structural diagram of a pulsator in the pulsator assembly of the present invention; Figure 3 is a top view of the pulsator in the pulsator assembly of the present invention; Figure 4 is a diagram of 3 Sectional view along the A-A direction.

As shown in FIGS. 1 to 4 , in order to solve the problems of low washing efficiency and poor washing spray effect existing in the pulsator of the existing washing machine, the pulsator assembly of the present invention mainly includes an inner tub bottom 1 and a pulsator 2 , and the inner tub bottom 1 includes The annular base 11 and the flange 12 arranged in the center of the annular base 11, the flange 12 is provided with a flange hole 121, and the annular base 11 has an inner annular surface (not shown in the figure).

The width gradually decreases along the flow direction of the wash water.

The pulsator assembly of the present invention can be generated by the water repellent ribs 22 during operation by enclosing the wheel disc 21 and the inner annular surface to form an annular water outlet channel, and the width of the water outlet channel gradually decreases along the flow direction of the washing water. Centrifugal force makes the washing water flow naturally along the water outlet channel and finally form a water jet from the channel opening, instead of directly hitting the inner tub bottom 1 along the radial direction of the wheel disc 21, which greatly enhances the spray effect and improves the washing efficiency. In other words, the present invention solves the problems of poor washing spray effect and low washing efficiency existing in the pulsator 2 of the existing washing machine, effectively improves the spray effect and washing efficiency, and is suitable for large-scale promotion.

Further referring to FIG. 4 , the flange 12 is connected to the inner hole of the annular seat body 111 , and a flange hole 121 is opened in the center of the flange 12 . The annular base 11 further includes a base body 111 and an annular cover 115 covered on the base body 111 , the upper surface of the base body 111 and the lower surface of the annular cover 115 form the above-mentioned inner annular surface, and the upper surface of the annular cover 115 The diameter of the surrounding inner hole is smaller than the diameter of the outer edge of the pulsator 2 , and the pulsator 2 is located in the cavity formed by the upper surface of the base body 111 and the lower surface of the annular cover 115 . For example, as shown in FIG. 4 , an annular platform 113 is provided on the upper surface of the base body 111 , and the annular cover 115 is embedded in the annular platform 113 . Preferably, the upper surface of the seat body 111 has a first inner annular surface 112 , the lower surface of the annular cover 115 has a second inner annular surface 116 , and the first inner annular surface 112 and the second inner annular surface 116 smoothly transition. Of course, the curvatures of the first inner annular surface 112 and the second inner annular surface 116 can be adjusted based on different application scenarios, and even the first inner annular surface 112 and/or the second inner annular surface 116 can be replaced by inclined surfaces.

Referring to FIGS. 2 , 3 and 4 , the roulette 21 is roughly in the shape of a bowl, a protrusion is provided in the center thereof, and a shaft hole 28 is extended downward from the center of the lower surface of the protrusion. The upper surface of the wheel disc 21 is provided with four water-repelling blades 25 , and each water-repelling blade 25 extends from a protrusion to the outer edge of the upper surface of the wheel disc 21 along the radial direction of the wheel disc 21 . Five friction ribs 26 are arranged between every two water-repellent blades 25 , each friction rib 26 is arranged along the radial direction of the wheel disc 21 , and between every two friction ribs 26 and the adjacent friction ribs 26 are connected to the water-repellent. A plurality of second water outlet holes 27 are provided between the leaves 25 . The lower surface of the wheel disc 21 is provided with three annular reinforcing ribs 24 and a plurality of water-repellent ribs 22 , and each water-repellent rib 22 extends from the second reinforcing rib 24 to the outer edge of the wheel disc 21 along the radial direction of the wheel disc 21 . . The outer edge of the wheel disc 21 also has a downward flange 23 , and the flange 23 smoothly transitions with the outer edge of the wheel disc 21 . In the assembled state, the lower surface of the wheel disc 21, the flange 23, the first inner annular surface 112 and the second inner annular surface 116 together form a water outlet channel, and the pulsator 2 is located in the first inner annular surface 112 and the second inner annular surface 112. In the cavity formed by the annular surface 116, the width of the water outlet channel gradually decreases along the flow direction of the washing water, especially the width of the gap between the flange 23 and the second inner annular surface 116 decreases rapidly.

The working principle of the pulsator assembly of the present invention will be briefly described below with reference to FIG. 2 and FIG. 4 .

As shown in Figures 2 and 4, when the pulsator assembly is working, the driving device drives the wheel disc 21 of the pulsator 2 to rotate. During the rotation, the water-repelling blade 25 drives the washing water above the wheel disc 21 to generate eddy currents, and friction The rib 26 rubs and washes the clothes, and the centrifugal force generated by the water repellent rib 22 throws out the washing water under the wheel disc 21, and then the washing water is naturally pushed into the annular water outlet channel along the radial direction of the wheel disc 21. 2, a large amount of washing water is pushed into the annular water outlet channel, and rises along the first inner annular surface 112 and the second inner annular surface 116, and the width of the annular water outlet channel gradually decreases along the flow direction of the washing water. Small, the gap between the flange 23 and the second inner annular surface 116 is the smallest, so the washing water is rapidly pressurized during the flow process, and finally passes through the channel opening to form a strong high-pressure jet of water to be sprayed obliquely upwards. On the one hand, the water flow collides with the eddy current to form a turbulent flow, and on the other hand, it sprays the clothes.

It can be seen from the above description that the water outlet channel is formed by the lower surface of the wheel disc 21, the flange 23, the first inner annular surface 112 and the second inner annular surface 116, and the width of the water outlet channel gradually decreases along the flow direction of the washing water. With a small setting mode, the pulsator assembly of the present invention can generate annular jet water flow during operation. On the one hand, the strong water flow collides with the eddy current to form turbulent flow, changes the single flow direction of the eddy current, significantly enhances the washing effect, and effectively prevents the entanglement of clothes. On the other hand, by spraying the clothes, the degree of wear of the clothes by the impeller 2 is reduced, and the cleaning degree of the clothes is greatly improved. The width of the water outlet channel is gradually reduced along the flow direction of the washing water, so that the water outlet channel is gradually narrowed and the pressure is gradually increased during the flow of the washing water, which ensures the pressure and spray effect of the water jet. The arrangement of the flanges 23, on the one hand, improves the strength of the pulsator 2, and on the other hand greatly reduces the possibility that the edge of the roulette 21 will damage the clothes. The arrangement of the pulsator 2 in the cavity formed by the first inner annular surface 112 and the second inner annular surface 116 can effectively change the spraying direction of the water flow, so that the water flow can be concentrated to the center, thereby improving the spraying effect and washing efficiency.

It should be noted that the above-mentioned embodiments are only used to illustrate the principle of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can carry out any form of modification to the structure of the present invention without departing from the principle of the present invention. adjustment so that the present invention can be applied to more specific application scenarios. For example, the inner tub bottom 1 may also be an integral structure, as long as the integral structure can form a water outlet channel with the wheel disc 21; for another example, the water repellent ribs 22 may not be provided on the lower surface of the wheel disc 21, The lower surface of the wheel disc 21 is set in a shape that can repel water; for another example, the seat body 111 and the annular cover 115 can also be connected in other ways, for example, the upper surface of the seat body 111 and the lower surface of the annular cover 115 have protrusions and The groove is fixed in position by plugging into the groove as expected; another example, the shape of the wheel disc 21 can also be a disk or other forms; The numbers of the water outlet holes 117 , the second water outlet holes 27 , the water repelling ribs 22 and the reinforcing ribs 24 are not limited, as long as the number can be beneficial to improve the washing effect and the spraying effect.

A water outlet hole 117, each of the notches 114 and the corresponding first water outlet hole 117 form an upper water channel. Preferably, the two upper water gushing channels can be provided corresponding to one lint filter respectively (if there are two in the washing tub). In this way, when the pulsator assembly is working, under the centrifugal action of the water-repellent ribs 22, the washing water is not only sprayed outward from the water outlet channel, but also a part of the washing water can be sprayed upward from the upper water channel. When the water flows through the lint filter , can enhance the lint filtering effect and spraying effect. Of course, the number of the notches 114 and the corresponding first water outlet holes 117 is not limited, and those skilled in the art can adjust the number to improve the filtering or spraying effect.
