Any part of the washing machine can be flexibly selected as the supporting part by a person skilled in the art according to the actual situation as long as the lifting of the clothes can be realized through the lifting of the supporting part. The technical scheme of the invention is explained in detail below by taking the washing machine as a pulsator washing machine and the supporting piece as an example.
Referring to fig. 1 and 2, fig. 1 and 2 are schematic structural views of an embodiment of a laundry lifting mechanism for a washing machine according to the present invention. As shown in fig. 1 and 2, the washing machine includes a housing 1, a washing tub 2 (including an inner tub and an outer tub), an outer tub cover 3, and a balance ring 4, the pulsator 2 is provided in the washing tub, the laundry lifting mechanism includes a telescopic member 6 provided above the pulsator 5, and in an assembled state, the telescopic member 6 can directly drive the laundry to move upward in an inflated process.

Further, instead of providing the extensible member 6 above the pulsator 5, the extensible member 6 may be provided below the pulsator 5. Referring to fig. 3, fig. 3 is a schematic structural view of the embodiment of the laundry lifting mechanism of the present invention. As shown in fig. 3, the telescopic member 6 can drive the pulsator 5 to move up and down, that is, in an assembled state, the telescopic member 6 can indirectly drive the clothes to move up by driving the pulsator 5 in an inflating process. Similarly to the above, the clothes can be lifted by driving the pulsator 5 through the telescopic member 6, and the technical effects of facilitating the user to take the clothes and facilitating the user to observe the inside of the washing tub 2 so as to avoid the condition of clothes omission can be obtained. In addition, compare in the mode that the axle transmission drove impeller 5 and remove, adopt the mode of gas inflation to drive impeller 5 and remove and can reduce impeller 5's noise and vibration to a certain extent, compare in the mode of axle transmission more softly to improve washing machine operation's stability and promote user experience to a certain extent.
Preferably, the telescopic element 6 is conformed to the surface of the support element in the completely deflated condition of the telescopic element 6.

In a possible embodiment, the telescopic part 6 is arranged above the impeller 5, the inflation duct and the air exhaust duct both pass through a motor shaft of the motor 9 for driving the impeller 5 to rotate, and through the design of the structure, a through hole for the inflation duct and the inflation duct to pass through can be not required to be additionally arranged at the bottom of the washing tub 2, so that the condition that the washing tub 2 leaks water due to poor sealing performance of the washing tub 2 is avoided. Of course, the air charging duct and the air exhaust duct are not limited to the above-mentioned exemplary structures and arrangement forms, and may be in other structural forms, for example, a through hole through which the air charging duct and the air exhaust duct can pass may be formed in the side wall of the washing tub 2, so that the air charging pump charges the expansion piece 6 through the air charging duct and the air exhaust duct exhausts the expansion piece 6 through the air exhaust duct, and this structure does not need to change the structure of the motor 9, thereby avoiding the increase of the manufacturing cost due to the change of the structure of the motor 9. The person skilled in the art can flexibly arrange and design the structure of the gassing lines and the suction lines and their arrangement in practical applications, as long as the transport of gas can be achieved by a reasonable arrangement of the gassing lines and suction lines and as far as possible without changing the structure of the washing tub 2.
In another aspect, the present invention also provides a washing machine including the laundry lifting mechanism of any one of the above and a controller for: when the door/door cover of the washing machine is detected to be opened, the expansion piece 6 is controlled to be inflated; when no laundry is detected in the washing tub 2, the telescopic member 6 is controlled to be evacuated. In actual application, to the extensible member 6 can drive impeller 5 and then drive the clothing and remove as an example, when the user opened washing machine door/door closure, the controller can make extensible member 6 inflated, utilize the inflation effect of extensible member 6 to rise impeller 5, thereby make the clothing rise, thereby realize the rising of clothing in the washtub 2, convenient to use person takes the clothing, and convenient to use person observes the surplus condition of clothing in washtub 2, avoid appearing the condition of omitting the clothing. When the user finishes taking out the clothes, the controller controls the telescopic piece 6 to be gradually pumped, so that the gas in the telescopic piece 6 is gradually reduced, and the telescopic piece 6 is controlled to be restored to the initial state and the impeller 5 is restored to the original position. The control mode of gradually reducing gas can prevent the impeller 5 from falling rapidly to impact the washing barrel 2 to damage the internal structure due to the gas being pumped away rapidly, and the operation stability and safety of the washing machine are improved. For an intelligent washing machine (taking a pulsator washing machine with a clothes recognition device as an example), a clothes recognition device such as an image acquisition device and a radio frequency recognition device which can detect whether clothes to be taken exist in a washing tub 2 can be arranged in the washing machine, before a user opens a machine door/door cover of the washing machine, the clothes recognition device can feed back a signal indicating whether clothes exist in the washing tub 2 to a controller for analysis, the controller judges whether clothes exist in the washing tub 2, if the controller judges that clothes exist in the washing tub 2, the user is reminded to open the machine door/door cover of the washing machine to take out the clothes, when the user opens the machine door/door cover of the washing machine, the telescopic piece 6 is controlled to be inflated to lift the pulsator 5 so as to take the clothes, and after the clothes are taken out, the telescopic piece 6 is controlled to be pumped to lower the pulsator 5 and restore the original position. If the controller judges that the laundry is not stored in the washing tub 2, the user is reminded that the laundry fetching operation is not required. By adopting the control mode of automatic detection and automatic control of clothes lifting, the user only needs to take the clothes in the whole operation process, so that the convenience of taking the clothes by the user is further improved, and the operation experience of the user is improved.
In addition, in the technical solution of the present invention, the extensible member 6 may be an airbag or other member capable of expanding in volume when being inflated and contracting in volume when being deflated, and those skilled in the art can flexibly adjust and design the structure of the extensible member 6 in practical applications as long as the lifting of the clothes can be realized through the expansion and contraction of the extensible member 6.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
