[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] See also Figure 1-Figure 4The utility model discloses a washing machine, including a body 10, a cleaning assembly and a driving assembly, wherein a receiving cavity 11 is provided in the body 10. The cleaning assembly includes a spin-drying cylinder 20 and a pulsator 30, wherein the spin-drying cylinder 20 is rotatably mounted in the receiving cavity 11, and the pulsator 30 is rotatably mounted in the spin-drying cylinder 20.

[0032] Specifically, the driving assembly includes a driving member 41, a driving seat 43, a driving shaft 42 and a check member. The driving seat 43 is connected to the bottom end of the dehydration cylinder 20. The driving shaft 42 is installed in the accommodating cavity 11, and one end of the driving shaft 42 is formed as a driving end, and the other end of the driving shaft 42 is formed as a transmission end. The driving end of the driving shaft 42 extends into the dehydration cylinder 20 through the driving seat 43 and is connected to the impeller 30. The driving member 41 can drive the transmission end to rotate, and the rotation of the transmission shaft of the driving shaft 42 can drive the driving shaft 42 to rotate as a whole.

[0033] The check member is arranged on the driving end, and when the driving shaft rotates around the first direction, the check member guides the rotation of the impeller; when the driving shaft rotates around the second direction, the check member can guide the rotation of the dehydration cylinder.

[0034] Specifically, based on the above structure, when the washing machine of the utility model is used, the washing machine has a washing state and a dehydration state:

[0035] In the washing state, the clothes can be put into the dehydration drum 20 in the accommodating chamber 11, and the driving member 41 can be started. The driving member 41 can drive the driving shaft 42 to rotate around the first direction. When the transmission end of the driving shaft 42 rotates around the first direction, due to the setting of the check member, the inner circle of the check member is connected to the driving end of the driving shaft 42, guiding the impeller 30 of the dehydration drum 20 to rotate. At this time, the impeller 30 rotates in the dehydration drum 20. In this state, the dehydration drum 20 can be non-rotating or driven by inertia to have a lower rotation speed (which can increase the water flow rate) when the impeller 30 rotates, and the impeller 30 can rotate relative to the dehydration drum 20 in the dehydration drum 20, so that the impeller 30 can move water and clothes in the dehydration drum 20, increase the water flow rate, and realize the cleaning of clothes with good cleaning effect.

[0036] In the dehydration state, the driving member 41 is started, and the driving member 41 can drive the driving shaft 42 to rotate around the second direction. The driving member 41 can drive the driving shaft 42 to rotate around the second direction. When the transmission end of the driving shaft 42 rotates around the second direction, the inner ring of the check member is stuck with the driving end of the driving shaft 42. The rotation of the driving shaft 42 drives the check member to rotate as a whole. The driving shaft 42 rotates as a whole, driving the driving seat 43 connected to the outer ring of the check member to rotate, and then drives the dehydration cylinder 20 to rotate together. The impeller 30 and the dehydration cylinder 20 rotate together at high speed, and high-speed dehydration can be performed; and the impeller 30 can rotate with the dehydration cylinder 20 in the dehydration cylinder 20, and throw out water inside to improve the dehydration effect.

[0037] Specifically, see Figure 1-Figure 4 The check member in this embodiment is a one-way bearing in the prior art. The one-way bearing 44 is mounted on the outside of the driving end, and the inner ring of the one-way bearing 44 is connected to the driving end, and the outer ring of the one-way bearing 44 is connected to the driving seat 43; the one-way bearing 44 can guide the impeller 30 to rotate when the driving shaft 42 rotates in a first direction, and the one-way bearing 44 can guide the dehydration cylinder 20 to rotate when the driving shaft 42 rotates in a second direction.

[0038] That is, in the present application, the same driving member 41 drives the driving shaft 42 to rotate in two opposite directions, and the one-way bearing 44 is used to guide the rotation, so as to realize the functions of washing and dehydrating clothes, and the washing effect is good, and the dehydration effect is good. There is no need to set up multiple motors or clutches, which simplifies the driving structure and reduces the production cost.

[0039] It should be noted that the one-way bearing 44 is a prior art, and its specific structure and working principle do not belong to the technical content to be protected by this application, and will not be described in detail here.

[0040] Furthermore, a rotating sleeve 431 can be provided on the driving seat 43, and the above-mentioned driving end extends into the dehydration cylinder 20 through the rotating sleeve 431 to be connected to the impeller 30. The driving end is installed in the rotating sleeve 431 through a one-way bearing 44, and the outer ring of the one-way bearing 44 is connected to the rotating sleeve 431.

[0041] In this way, when installing the one-way bearing 44, the one-way bearing 44 can be assembled into the rotating sleeve 431 of the driving seat 43, with the outer ring of the one-way bearing 44 connected to the inner wall of the rotating sleeve 431, so as to achieve the positioning and assembly of the one-way bearing 44, and the outer ring of the one-way bearing 44 acts on the rotating sleeve 431, and concentrates the action on the rotating sleeve 431 of the driving seat 43 to provide driving force, making it easier to increase the rotation speed of the driving seat 43 and the dehydration drum 20 connected to the driving seat 43.

[0042] Furthermore, a first through hole is provided at the top of the rotating sleeve 431, and the driving end extends into the dehydration barrel 20 through the first through hole, and a first sealing ring 45 is clamped between the inner wall of the first through hole and the outer wall of the driving end. In this way, the first sealing ring 45 can be used to seal the connection position between the driving end of the driving shaft 42 and the dehydration barrel to prevent water leakage at the assembly position, thereby improving the sealing of the internal parts of the rotating sleeve 431.

[0043] Furthermore, the bottom end of the rotating sleeve 431 is sealed with a pressure cover 46, and a second through hole is provided on the pressure cover 46; the driving shaft 42 extends into the rotating sleeve 431 through the second through hole, so that the driving shaft 42 can penetrate into the rotating sleeve 431 through the second through hole of the pressure cover 46, and a second sealing ring 47 is clamped between the inner wall of the rotating sleeve 431 and the outer wall of the driving end. The second sealing ring 47 is used to seal the bottom end of the rotating sleeve 431, which can also improve the sealing of the internal parts of the rotating sleeve 431.

[0044] Furthermore, a one-way bearing 44 and a sealing rubber pad can be provided in the rotating sleeve 431, and the sealing rubber pad is provided above or below the one-way bearing 44 and is sleeved outside the driving shaft 42, so that the driving shaft 42 can be guided by a one-way bearing 44 to guide the pulsator 30 and the dehydration cylinder 20 to be used in different states when the driving shaft 42 is turned in different directions. The sealing rubber pad provided above or below the one-way bearing 44 can further improve the sealing performance.

[0045] Of course, the rotating sleeve 431 may be provided with a one-way bearing 44 and a rotating bearing, and the one-way bearing and the rotating bearing may be distributed up and down, so that the one-way bearing 44 may guide the driving shaft 42 to rotate under different working conditions, and the rotating bearing may be an ordinary bearing in the prior art to increase the rotation stability of the driving shaft.

[0046] It should also be noted that two one-way bearings 44 may be provided in the rotating sleeve 431, and the two one-way bearings 44 may be distributed up and down. In this way, the inner rings of the two one-way bearings 44 may be connected to the drive shaft 42, and the outer rings of at least two one-way bearings 44 may be connected to the drive seat 43, so that the transmission structure is more stable.

[0047] See also Figure 5 as well as Figure 6 The non-return member in this embodiment is a ratchet pawl mechanism in the prior art, specifically comprising a ratchet and a non-return pawl. The ratchet is sleeved outside the driving shaft. The non-return pawl can slide with the tooth groove of the ratchet when the driving shaft rotates in a first direction, that is, the non-return pawl can slide on the tooth groove of the ratchet, so that the driving shaft can drive the connected impeller to rotate. When the driving shaft rotates in a second direction, the non-return pawl can engage with the tooth groove of the ratchet to limit the rotation of the ratchet. At this time, the driving seat on which the pawl is installed rotates together as a whole, that is, the dehydration cylinder is driven to rotate together.

[0048] Furthermore, the above-mentioned drive seat 43 is sealed and connected to the bottom end of the dehydration cylinder 20, and is fixedly connected to the inner wall of the bottom end of the dehydration cylinder 20, that is, the drive seat 43 is formed as the bottom wall of the dehydration cylinder 20. Specifically, the drive seat 43 can be directly formed on the bottom end of the dehydration cylinder 20, or it can be assembled on the bottom end of the dehydration cylinder 20 by means of screws and other structures. The drive seat 43 is directly the bottom end structure of the dehydration cylinder 20. When the drive shaft 42 drives the dehydration cylinder 20 to rotate, it is a direct drive, and the rotation speed is higher during rotation.

[0049] Furthermore, abutting steps can be provided on the outer periphery of the bottom end of the driving seat 43, and the bottom peripheral edge of the dehydration cylinder 20 is against the abutting steps, and the inner wall of the dehydration cylinder 20 is provided with a plurality of protruding blocks, and the bottom end of the protruding block located at the bottom of the inner wall of the dehydration cylinder 20 is against the top peripheral edge of the driving seat 43. In this way, the plurality of protruding blocks form an uneven situation on the inner wall of the dehydration cylinder 20, which can make it easier to throw out the water flow during dehydration, and the dehydration effect is better. The abutting steps of the bottom protruding block and the driving seat 43 realize the upper and lower limit of the driving seat 43, and improve the assembly stability of the driving seat 43.

[0050] Furthermore, a plurality of reinforcing ribs are provided at the bottom end of the drive seat 43, and the reinforcing ribs extend along the radial direction of the drive seat 43, and the plurality of reinforcing ribs are spaced apart in the circumferential direction of the drive seat 43. In this way, the drive seat 43 is reinforced by reinforcing ribs in both the circumferential and radial directions, and the strength of the drive seat 43 is better, and the transmission of the drive seat 43 is more stable when rotating.

[0051] Furthermore, the driving member 41 includes a driving motor, and the rotating shaft of the driving motor is connected to the transmission end. That is, in this embodiment, the rotating shaft of the driving motor drives the driving shaft 42 to rotate, and the driving structure is simple and stable.

[0052] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
