Problems solved by technology

[0005] However, in the above scheme, the position of the upper wave wheel is fixed. When the amount of laundry is small and the washing water level is significantly lower than the height of the upper wave wheel, the upper wave wheel cannot touch the washing water, and thus cannot participate in the washing process. Relying on the lower wave wheel to achieve the washing effect of a single wave wheel

Embodiment 1

[0058] Such as Figure 1 to Figure 5 As shown, the present embodiment provides a pulsator assembly and a washing machine including the pulsator assembly.

[0059] Specifically, the pulsator assembly includes:

[0060] The first wave wheel 200;

[0061] The second pulsator 400 is arranged above the first pulsator 200;

[0062] The connecting piece 300 is used for connecting the first pulsator 200 and the second pulsator 400 .

[0063] The second pulsator 400 is mounted on the connecting member 300 so as to be relatively movable, and the second pulsator 400 moves closer to or away from the first pulsator 200 relative to the connecting member 300 .

[0064] The washing machine in this embodiment specifically includes an inner tub, and the above-mentioned pulsator assembly disposed inside the inner tub. Wherein, the first pulsator 200 is rotatably arranged at the bottom of the inner tub.

[0065] In this embodiment, a first stirring rib 201 is provided on the upper surface of...

Embodiment 2

[0089] This embodiment is a further limitation of the first embodiment above. A limiting device is provided on the connecting portion, and the limiting device is installed above the second pulsator to limit the highest sliding position of the second pulsator.

[0090] During the laundry process, especially when the washing speed is high and the weight of the second pulsator is relatively light, the second pulsator may slide up a large distance along the connecting part during the rotation process, causing the second stirring rib to sink into the water surface. Partially reduced, or even completely separated from the washing water, resulting in weakened agitation of the washing water, and unable to produce effective friction with the clothes to achieve the ideal washing effect.

[0091] In this embodiment, by providing a limiting device on the connecting part that can limit the second pulsator, the highest position that the second pulsator can reach when sliding on the connectin...

Embodiment 3

[0100] Such as Figure 1 to Figure 5 As shown, this embodiment is a further limitation of the first embodiment above, and the second pulsator 400 is provided with a weight adjusting device that can adjust the weight. The user can adjust the weight of the weight adjusting device to realize the adjustment of the overall weight of the second pulsator 400, especially when the wetness of the laundry is poor, the second pulsator 400 can have enough weight to fully wash the clothes. Press into the water to ensure the garment is fully soaked.

[0101] At the same time, adjusting the overall weight of the second pulsator 400 to an appropriate level for different washing speeds and washing water conditions can also ensure that the second pulsator 400 floats stably at the height of the water surface during the entire washing process, avoiding the second wave The wheel 400 falls off the water surface too lightly, or sinks into the bottom of the water too heavily, so as to ensure the effe...

Abstract

The invention belongs to the technical field of washing machines, and discloses an impeller assembly and a washing machine. The impeller assembly comprises a first impeller, a second impeller arranged above the first impeller, and a connecting piece used for connecting the first impeller and the second impeller, wherein the second impeller is installed on the connecting piece in a relative movement mode, and the second impeller moves close to or away from the first impeller relative to the connecting piece. According to the impeller assembly, the first impeller and the second impeller are connected through the connecting piece, and the second impeller can move relative to the connecting piece; the impeller assembly is applied to the washing machine; the position of the second impeller can be adjusted in an inner barrel, and therefore the second impeller can be located at the height close to the water surface at different washing water levels; the first impeller and the second impeller simultaneously stir water flow from the bottom and the top in the clothes washing process, so that the cleaning effect is enhanced; and meanwhile, the second impeller can shield the water flow, so that the water splashing problem in the clothes washing process is prevented.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a wave wheel assembly and a washing machine. Background technique [0002] Traditional pulsator washing machines generally only have a pulsator at the bottom of the inner tub, and the washing function is mainly realized by the rotation of the pulsator. Specifically, when the washing machine is working, the pulsator rotates at the bottom of the inner tub of the washing machine to stir the water flow at the bottom of the inner tub, causing the water flow to generate impact force and rub against the clothes, and at the same time drive the clothes to roll in the inner tub, causing friction between the clothes, so as to achieve washing purpose of clothing. Since the pulsator can only stir the water flow at the bottom of the inner tub, when there are many clothes in the inner tub and the washing water level is high, the agitation effect on the washing water near t...
