When the washing machine is used, clothes are placed in the inner drum and positioned on the upper portion of the impeller, the motor drives the impeller to rotate through the driving shaft, and then the clothes in the inner drum are stirred through the impeller so as to wash the clothes.

In the impeller washing machine, the distance between the impeller and the bottom of the inner barrel is small, so that dirt is easily gathered between the impeller and the inner barrel and is difficult to remove.

The preferred technical scheme of the pulsator washing machine of the present invention is described below with reference to the pulsator washing machine.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a pulsator washing machine according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a pulsator 40 washing machine, including: an inner cylinder 10, a pulsator 40, a driving shaft 30, and a driving device 20; the bottom of the inner cylinder 10 is provided with a shaft hole, the driving shaft 30 is arranged in the shaft hole in a penetrating way, the driving device 20 is arranged outside the inner cylinder 10, and the bottom end of the driving shaft 30 is in transmission connection with the driving device 20; the impeller 40 is arranged inside the inner barrel 10, and the impeller 40 is connected with the top end of the driving shaft 30; the pulsator 40 partitions the inner tub 10 into an upper washing chamber and a lower washing chamber.

The pulsator 40 washing machine in this embodiment further includes a housing, the inner tub 10 and the driving device 20 are disposed in the housing, and the inner tub 10 is used for containing laundry and water, which is a place for washing. The driving device 20 may be a driving motor, and specifically, the driving motor may be a direct current motor or an alternating current motor. Further, the driving motor may be directly connected to the driving shaft 30 through a coupling; or the driving motor is connected with the driving shaft 30 through a speed reducer to reduce the rotating speed of the driving shaft 30, so as to avoid damage to the clothes due to the excessively high rotating speed of the driving shaft 30.

In this embodiment, a bearing may be disposed between the driving shaft 30 and the shaft hole to realize the connection between the driving shaft 30 and the inner cylinder 10. Further, in order to prevent the water in the inner tub 10 from flowing out through a gap between the drive shaft 30 and the shaft hole, it is necessary to perform a sealing process between the drive shaft 30 and the shaft hole, for example: a seal ring may be disposed within the shaft bore.

In this embodiment, the pulsator 40 is connected to the top end of the driving shaft 30; specifically, the driving shaft 30 may be connected to the pulsator 40 by welding to rotate the pulsator 40 while the driving shaft 30 rotates, thereby agitating the laundry and moving water in the drum 10 for washing.

The present embodiment preferably has the drive shaft 30 detachably connected to the pulsator 40. With such arrangement, the impeller 40 can be replaced with a new impeller 40 when the impeller 40 is damaged; in addition, a plurality of pulsator 40 may be provided, and the size of the pulsator 40 is different, and the pulsator 40 corresponding to the laundry is replaced according to the laundry before washing, to improve a washing effect.

In this embodiment, the pulsator 40 divides the inner tub 10 into an upper washing chamber and a lower washing chamber, and during washing, the laundry in the inner tub 10 can move in the upper washing chamber and the lower washing chamber to be washed; the contact area between the pulsator 40 and the laundry can be increased, and thus the stirring effect of the pulsator 40 is improved. It should be noted that the cross-sectional area of the pulsator 40 is smaller than the cross-sectional area of the inner tub 10, so that a flow channel is formed between the edge of the pulsator 40 and the sidewall of the inner tub 10, and the laundry and water may enter the lower washing chamber from the upper washing chamber through the flow channel, or the laundry and water may enter the upper washing chamber from the lower washing chamber through the flow channel.

With continued reference to fig. 1, in the present embodiment, the distance between the pulsator 40 and the bottom of the inner drum 10 is preferably smaller than the distance between the pulsator 40 and the top of the inner drum 10. With such an arrangement, the phenomenon that the distance between the impeller 40 and the top of the inner drum 10 is too small, and the clothes and water fly out of the top of the inner drum 10 when the impeller 40 rotates can be avoided.

Further, the distance between the pulsator 40 and the top of the inner tub 10 is twice as long as the distance between the pulsator 40 and the bottom of the inner tub 10, that is, the height of the lower washing chamber in the direction perpendicular to the horizontal plane is one third of the height of the inner tub 10.

The working process of the pulsator 40 washing machine provided by the embodiment is as follows: firstly, placing clothes in the inner drum 10, and injecting water into the inner drum 10, wherein the clothes are arranged in the upper washing cavity and the lower washing cavity; then, the driving shaft 30 is driven to rotate by the driving device 20, the driving shaft 30 drives the pulsator 40 to rotate, and the pulsator 40 agitates the clothes and water in the upper washing chamber and the lower washing chamber, so as to wash the clothes. After the washing is finished, the water in the inner tub 10 is discharged, and the laundry in the upper washing chamber and the lower washing chamber is taken out, so as to finish the washing of the laundry.

With this arrangement, the upper blade 401 and the lower blade 402 are simultaneously in contact with the laundry, and the friction between the pulsator 40 and the laundry can be increased, so as to further improve the stirring effect of the laundry.

Taking the orientation shown in fig. 1 as an example, specifically, the body 402 has a plate shape, the upper blade 401 is disposed on the upper surface of the body 402, and the lower blade 403 is disposed on the lower surface of the body 402. The upper blade 401 and the lower blade 403 may be connected to the body 402 by bolts, but the upper blade 401 and the lower blade 403 may be integrally formed with the body 402 by injection molding or casting.

The bottom of the inner cylinder 10 is provided with a shaft hole, the driving shaft 30 is arranged in the shaft hole in a penetrating way, the driving device 20 is arranged outside the inner cylinder 10, and the bottom end of the driving shaft 30 is in transmission connection with the driving device 20; the pulsator 40 is disposed inside the inner tub 10, and the pulsator 40 is connected to the top end of the driving shaft 30, and the inner tub 10 is partitioned into an upper washing chamber and a lower washing chamber by the pulsator 40. Through the arrangement, when washing, clothes move in the upper washing cavity and the lower washing cavity; compared with the impeller 40 arranged at the bottom of the inner cylinder 10, the impeller 40 has a larger distance from the bottom of the inner cylinder 10, and dirt is difficult to gather.

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.
