In the lifting and moving process of the pulsator component, clothes on the pulsator component can synchronously move along with the pulsator component and are dispersed under the action of water flow. After the pulsator member reciprocates for a plurality of times, the degree of entanglement of the laundry located above the pulsator member can be effectively reduced.

Example 1:

the embodiment provides a liftable impeller assembly, which comprises two parts of an impeller member and an auxiliary lifting mechanism 3, wherein the auxiliary lifting mechanism 3 is positioned on the periphery side of the impeller member and can drive the impeller member to move up and down.

In the process of the up-and-down movement of the pulsator component, clothes on the pulsator component can be scattered under the impact of water flow, so that the effect of solving or relieving the problem of clothes winding is achieved.

In this embodiment, the above-mentioned pulsator component includes pulsator mounting plate 1 and pulsator disc 2, wherein pulsator mounting plate 1 locates below pulsator disc 2, auxiliary lifting mechanism 3 locates outside pulsator mounting plate 1 and can drive pulsator mounting plate 1 to move up and down; the impeller mounting plate 1 can drive the impeller disc 2 to synchronously lift and move under the driving of the auxiliary lifting mechanism 3.

That is, the auxiliary lifting mechanism 3 is connected with the pulsator mounting plate 1 and drives the pulsator mounting plate 1 to lift and move, and the pulsator disc 2 structure above the pulsator mounting plate 1 can move synchronously under the driving of the pulsator mounting plate 1.

The following describes the structure of the auxiliary elevating mechanism 3:

the auxiliary lifting mechanism 3 comprises a chain with a fixing clamping groove, at least part of the chain can move up and down along the vertical line direction, and the outer side edge of the impeller mounting plate 1 can be connected with the chain through the fixing clamping groove.

That is, the pulsator mounting plate 1 can be fixedly connected with the chain through the fixing clip groove. When the chain is driven to move, the pulsator mounting plate 1 can synchronously lift and move under the pulling of the chain.

It should be noted that the chain may be a bar-shaped structure or a ring-shaped structure. The auxiliary elevating mechanism 3 includes a driving mechanism such as a sprocket corresponding to the chain, in addition to the chain. The driving structure in the prior art only needs to realize pulling and releasing of the chain so as to meet the lifting requirement of the impeller mounting plate 1, and the scheme does not limit the specific structure.

In this embodiment, at least part of the chain is provided on the side wall of the inner cylinder 5 in order to ensure that the chain can be firmly provided.

Specifically, a groove for accommodating a chain is formed on the side wall of the inner barrel 5, and the chain is positioned in the groove and can reciprocate up and down relative to the groove.

As an alternative embodiment, the number of chains is at least two and all the chains are uniformly arranged around the outer peripheral side edge of the pulsator mounting plate 1.

Under the pulling of the chain, the pulsator mounting plate 1 has a structure capable of moving up and down along the axial direction, and the pulsator disc 2 can move up and down under the pulling of the pulsator mounting plate 1.

In order to realize firm connection between the chain and the pulsator mounting plate 1, as an alternative embodiment, the fixing slot is a groove structure, and the pulsator mounting plate 1 is fixedly connected with the chain through the groove.

Alternatively, the peripheral side edge of the portion of the pulsator mounting plate 1 may be embedded in the groove of the chain in an embedding manner, so as to ensure that the pulsator mounting plate 1 is firmly connected with the chain.

It should be noted that the pulsator mounting plate 1 and the pulsator plate 2 are independently provided. There is only a synchronization of the movement state in the up-down direction between the two. When the pulsator mounting plate 1 is at the lowest position, the pulsator disc 2 can perform washing work normally at this time.

As an alternative embodiment, the pulsator component further comprises an output shaft 4 connected with the pulsator disc 2, the output shaft 4 is detachably connected with the pulsator disc 2, and when the pulsator disc 2 is driven by the pulsator mounting plate 1 to lift and move, the pulsator disc 2 can be connected with or separated from the output shaft 4.

When the impeller disc 2 is positioned at the lowest position, the impeller disc 2 is connected with the output shaft 4 and can rotate under the drive of the output shaft 4, so that liquid in the inner cylinder 5 is stirred, and washing operation is realized. At this time, the pulsator mounting plate 1 is stationary.

It should be noted that the output shaft 4 and the impeller disc 2 are detachably connected, and the specific connection manner is the prior art, and the structure thereof is not limited in detail.

In this embodiment, the impeller disc 2 is connected to the output shaft 4 by a ball quick-release member. When the wave wheel disc 2 moves upwards along the vertical line direction, the wave wheel disc and the wave wheel disc are separated; when the roulette wheel 2 moves down to the initial position in the vertical direction, the two are connected. That is, the pulsator 2 and the output shaft 4 can rapidly complete the dismounting operation by the up-and-down movement.

It can be understood that the technical solution provided in this embodiment can adjust the connection relationship between the impeller disc 2 and the output shaft 4 by controlling the position of the impeller disc 2 in the vertical direction by the auxiliary lifting mechanism 3, and when the impeller disc 2 is connected with the output shaft 4, the washing operation can be normally performed at this time; when the two are separated, the impeller disc 2 can drive clothes to lift in water, so that the intertwined clothes are scattered under the impact of water flow, and the effect of reducing the intertwined clothes is achieved.

Example 2:

the embodiment provides a washing machine, which comprises the liftable impeller assembly, and further comprises an inner cylinder 5, wherein at least part of the auxiliary lifting mechanism 3 is positioned on the inner cylinder 5.

As shown in fig. 1, in the present embodiment, a part of the chain of the auxiliary elevating mechanism 3 is provided on the side wall of the inner cylinder 5. The inner cylinder 5 is also provided with a balance ring 7, and the auxiliary lifting mechanism 3 is positioned below the balance ring 7.

The washing machine also comprises a winding judging component 6 arranged above the inner cylinder 5

The winding judgment unit 6 may be directly provided on the upper edge of the inner tub 5, or may be provided at any position of the washing machine above the inner tub 5.

In the present embodiment, the above-described winding judgment member 6 is an image pickup apparatus and the photographing angle of the image pickup apparatus can cover the entire liquid surface of the inner cylinder 5.

Specifically, the image pickup apparatus is a high-speed camera. The high speed camera is able to take a complete liquid level of the inner cylinder 5.

After the washing machine enters a washing program, the high-speed camera can capture dynamic positions of clothes during washing in the form of pictures or videos, and judge the aggregation degree of the clothes positioned at the core. If the clothes are gathered to exceed a certain value, the washing is stopped, and the auxiliary mechanism is started to drive the pulsator component to perform lifting and reciprocating motion, as shown in fig. 1-2. During the lifting and reciprocating movement of the pulsator component, the water current can be utilized to wash and unwind the clothes. The washing process may then be continued, thereby achieving the objective of controlling the degree of entanglement of the laundry during the washing process to reduce entanglement of the final laundry.

The washing flow of the washing machine will be described as follows:

as shown in fig. 3, the laundry is placed in the inner tub 5 of the washing machine, and the washing process is started, and at this time, the output shaft 4 drives the pulsator 2 to agitate the washing water in the inner tub 5 to twist the laundry (a part of the water flows between the inner tub 5 and the outer tub 8). After the washing process is performed for 5 minutes, the high speed camera starts to take a picture of the state of the laundry in the drum 5, and if 50% of the laundry in the taken picture is gathered or involved in the vortex core, the washing is immediately suspended. After the liquid level is stable, the auxiliary lifting mechanism 3 drives the impeller disc 2 to reciprocate up and down through the impeller mounting plate 1, and the impeller disc 2 moves together with the impeller mounting plate 1 and is separated from the output shaft 4 in the process. In this process, the impeller disc 2 can be lifted to enable the opposite flushing water flow to break up clothes, and when the impeller disc 2 descends, the clothes can be broken up by the acting force of the washing water on the clothes opposite to the moving direction of the clothes due to the left and right buoyancy. After such a reciprocation for 3min (wherein, the reciprocation goes upward for 5s, pauses for 5s, then goes downward for 5s, pauses for 5s, and can reciprocate according to the above-mentioned time period), the roulette wheel 2 falls back to the initial position and is fixed to the output shaft 4. After the fixing of the two is finished, the system synthesizes the residual washing time to judge whether the washing process is finished or not: draining water when washing is finished, and continuing washing when washing is not finished, so that the washing is repeated.

It should be noted that:

after the rotation of the impeller disc 2 is stopped, the liquid level can be restored to calm within 30 seconds, and at the moment, the auxiliary lifting mechanism 3 can be controlled to pull the impeller disc 2 to reciprocate up and down.

In addition, the shooting of the high-speed camera and the image distinguishing process are carried out in the washing process, but the image distinguishing process is within 20-30s of stopping the rotation of the impeller disc 2. The specific method for distinguishing the images of the high-speed camera comprises the following steps: the record is recorded on the clothes and the quantity is recorded, and the sample capacity of the 50% judgment limit is changed along with the change of the record quantity.

Specifically, assuming that 10 pieces of clothes are shared in an image shot by the high-speed camera, if at least 5 pieces of clothes are gathered or involved in the vortex core, the washing needs to be suspended at the moment to carry out reciprocating lifting treatment; otherwise, the normal washing procedure is continued.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
