The positioning structure 3 is arranged on the lower side surface of the cover plate body 1 in a sliding mode, when the fan blade 2 is located at the folding position, the fan blade 2 is embedded into the sliding groove, and the positioning structure 3 is abutted against the lower side of the fan blade 2 so that the fan blade 2 is kept at the folding position; when the washing barrel is dehydrated, the washing barrel rotates at a certain speed, the positioning structure 3 slides relative to the cover plate body 1 until the positioning structure 3 and the fan blades 2 are released from abutting against each other, the fan blades 2 slide out of the sliding grooves under the action of gravity, finally, the upper ends of the fan blades 2 abut against the lower ends of the sliding grooves, and the fan blades 2 slide to the unfolding position.

Through the above arrangement scheme, the fan blades 2 can be completely retracted, and the fan blades 2 can be prevented from scratching clothes in the washing process. Meanwhile, the fan blade 2 can be automatically unfolded during dehydration, and the use is convenient.

In a possible embodiment, the sliding groove is vertically arranged, so that the fan blades 2 are vertically arranged after sliding out of the sliding groove, the disturbance effect on the air flow is stronger, and stronger air flow can be generated.

In an alternative embodiment, the chute is inclined, and when the fan blade 2 slides out of the chute, the fan blade 2 slides backwards along the direction of the dehydrating rotation of the cover plate body 1.

Through the arrangement mode, when the fan blades 2 slide out of the sliding grooves, the air flow has backward thrust (taking the rotary dehydration direction of the cover plate body 1 as a reference) on the fan blades 2, and then the fan blades 2 can be rapidly unfolded.

Example 4

The present embodiment is different from embodiment 1 in that the fan blade 2 is fixed to the lower side surface of the cover plate 1.

Through the arrangement mode, the structure of the gland can be simplified, and the production cost is convenient to reduce.

In one possible embodiment, there are two blades 2, and the two blades 2 are disposed to cross each other.

It is further preferred to design the two fan blades 2 to pass through the axis of the cover body 1 and to be perpendicular to each other.

In a possible embodiment, the lower side of the fan blade 2 is provided in a circular arc shape to reduce damage of the fan blade 2 to the laundry during the washing process.

Although various specific examples of positioning structures 3 and articulating structures 4 have been set forth above, the scope of the present invention is not limited to these specific structures, and other structures may be selected as desired by those skilled in the art, provided that folding and unfolding of fan blades 2 can be achieved. For example, the positioning structure 3 may also be disposed on the periphery of the cover plate body 1 and can slide along the radial direction of the cover plate body 1, when the washing tub is dehydrated, the washing tub rotates at a certain speed, the positioning structure 3 is unfolded by the centrifugal force in a sliding manner along the radial direction of the cover plate body 1, so that the fan blades 2 are pivoted to the unfolded position under the neutral action; for another example, the movable connection structure 4 may also be a sliding groove arranged along the radial direction of the cover plate, and the fan blade 2 is slidably arranged in the sliding groove. When the washing barrel is dehydrated, the washing barrel rotates at a certain speed, and the fan blades 2 slide out of the sliding groove under the action of centrifugal force to slide to the unfolding position.

Example 5

The present embodiment provides a laundry treating apparatus including the pressing cover in any of the above embodiments.

Specifically, the laundry treating apparatus of the present embodiment is a pulsator washing machine, and the rotation shaft 42 of the washing tub is in a vertical direction.

In a possible embodiment, the washing tub is detachably connected to the cover body 1 of the gland by means of a snap, e.g. the cover body 1 is detachably connected to the balancing ring of the washing tub by means of a snap.

Through the arrangement mode, when the gland is detached, the opening on the upper side of the washing barrel can be completely opened, so that clothes can be taken and placed quickly.

In an alternative embodiment, one side edge of the cover plate body 1 is hinged with the washing tub, and the other opposite side edge is snap-connected with the washing tub, for example, one side edge of the cover plate body 1 is detachably connected with a balancing ring of the washing tub through a hinge, and the other opposite side edge is snap-connected with the balancing ring. Therefore, the pressing cover does not need to be detached when the clothes are taken and put, the pressing cover can be prevented from being stained with dust, and the cleanness can be kept conveniently.

Example 6

The present embodiment is different from embodiment 5 in that the washing tub of the laundry treating apparatus is disposed obliquely, and the rotation axis 42 of the washing tub makes an acute angle with the vertical direction.

Specifically, the clothes processing apparatus in this embodiment is an inclined drum washing machine, that is, the opening of the washing tub 42 is upward and is inclined in the casing, the peripheral side of the washing tub 42 is connected with a suspension mechanism, and two ends of the suspension mechanism are respectively fixedly connected with the peripheral side of the washing tub 42 and the inner side wall of the casing.

Example 7

The present embodiment is different from embodiment 5 in that the washing tub of the laundry treating apparatus is reversibly provided.

Specifically, the washing tub is tilted in a lateral direction when laundry is put into the washing tub, and the washing tub is erected in a vertical direction when washing, rinsing, and dehydrating are performed.

For example, patent application publication No. CN107923105A discloses a washing machine configured as above, and the structure thereof is not described herein again.
