When the clothes washing machine is used, clothes are placed in the inner cylinder and are located on the upper portion of the pulsator, the motor drives the pulsator to rotate through the driving shaft, and then the clothes in the inner cylinder are stirred through the impeller, so that clothes are washed.
In the pulsator washing machine, the distance between the pulsator and the bottom of the inner cylinder is small, so that dirt is easy to gather between the pulsator and the inner cylinder, and the dirt is difficult to clean.
The following describes a preferred technical scheme of the pulsator washing machine of the present invention in combination with the above pulsator washing machine.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an pulsator washing machine according to an embodiment of the present invention. Referring to fig. 1, an embodiment of the present invention provides a pulsator 40 washing machine including: an inner tube 10, a pulsator 40, a drive shaft 30, and a drive device 20; the bottom of the inner cylinder 10 is provided with a shaft hole, a driving shaft 30 is arranged in the shaft hole in a penetrating way, a 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 arranged inside the inner cylinder 10, and the pulsator 40 is connected with the top end of the driving shaft 30; the pulsator 40 divides 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, in which the inner tub 10 and the driving device 20 are disposed, and the inner tub 10 is used for containing clothes and water, and is a place for washing. The driving device 20 may be a driving motor, and in particular, the driving motor may be a direct current motor or an alternating current motor. Further, the driving motor may be directly connected with 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 rotation speed of the driving shaft 30, so as to avoid damage to clothes caused by too high rotation speed of the driving shaft 30.
In this embodiment, a bearing may be provided between the drive shaft 30 and the shaft hole to achieve connection between the drive shaft 30 and the inner cylinder 10. Further, in order to prevent water in the inner tube 10 from flowing out through a gap between the drive shaft 30 and the shaft hole, it is necessary to seal the gap between the drive shaft 30 and the shaft hole, for example: a sealing ring can be arranged in the shaft hole.
In this embodiment, the pulsator 40 is connected to the top end of the drive shaft 30; specifically, the driving shaft 30 may be connected to the pulsator 40 by welding, so as to rotate the pulsator 40 while the driving shaft 30 rotates, thereby stirring the laundry and water in the inner tub 10 to move, and washing.

The plurality of slide posts 508 are simultaneously contacted with the moving block 503, and when any slide post 508 is damaged, the use of the clamping device 50 is not affected; in addition, the plurality of slide posts 508 are simultaneously contacted with the movable block 503, and compared with the arrangement of only one slide post 508, the stress area of the movable block 503 can be increased, so that the movable block 503 is prevented from being damaged due to overlarge local stress.
Further, the sliding grooves are arranged at equal intervals around the center line of the hole, so that the moving block 503 is uniformly stressed, and the inclination caused by uneven stress of the moving block 503 when the pressing block 507 is pressed is avoided.
With continued reference to fig. 2-5, in this embodiment, the pulsator 40 washing machine further includes a cover 60, the cover 60 is covered on the upper portion of the clamping device 50, and the cover 60 is detachably connected to the pulsator 40. With this arrangement, the pulsator 40 is prevented from being separated from the driving shaft 30 due to the laundry touching the pressing block 507 during the washing process.
Specifically, the cover 60 may be connected to the pulsator 40 by bolting; further, the cover 60 may be connected to the pulsator 40 by means of a snap connection, so as to facilitate the disassembly and assembly of the cover 60.
In this embodiment, the cover 60 is provided with a detachment hole 601, and the detachment hole 601 is disposed opposite to the pressing block 507. Pressing the pressing block 507 through the disassembly hole 601 to achieve the installation and disassembly of the pulsator 40, the cover 60 does not need to be disassembled, and the rate of disassembly and installation of the pulsator 40 is improved.
In summary, the pulsator 40 washing machine of the embodiment of the present invention includes an inner tub 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, a driving shaft 30 is arranged in the shaft hole in a penetrating way, a 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 with the top end of the driving shaft 30, and the pulsator 40 partitions the inner tub 10 into an upper washing chamber and a lower washing chamber. With the arrangement, during washing, clothes move in the upper washing cavity and the lower washing cavity; the distance between the pulsator 40 and the bottom of the inner tub 10 is large, and it is difficult to collect dirt, as compared with the pulsator 40 disposed at the bottom of the inner tub 10.
Embodiments of the present invention so far, the technical solution of the present invention has 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 protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
