The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the present invention provides a laundry treating apparatus 10, and the laundry treating apparatus 10 includes a washing machine, a dryer, a washer-dryer, and the like.

In detail, the laundry treating apparatus 10 includes a washing tub 100 and a driving assembly 200.

In more detail, the washing tub 100 is used to contain laundry. The driving assembly 200 includes a driving wheel 210, a driving member 220, and a fastener 230.

The driving wheel 210 is in transmission connection with the washing tub 100, and the driving wheel 210 rotates to drive the washing tub 100 to rotate, for example, the driving wheel 210 is in transmission connection with the washing tub 100 through a transmission member, and the driving wheel 210 rotates to drive the transmission member to move, so as to drive the washing tub 100 to rotate to realize the functions of cleaning, dewatering, and the like.

The driving member 220 has an output shaft 221, and the driving member 220 includes a driving motor, for example. The output shaft 221 is connected to the drive wheel 210 to drive the drive wheel 210 to rotate.

As shown in fig. 1 and 3, the driving wheel 210 is provided with a first limiting structure 2111, the output shaft 221 is provided with a second limiting structure 222, and the first limiting structure 2111 and the second limiting structure 222 cooperate to limit the relative rotation between the driving wheel 210 and the output shaft 221. When the driving wheel 210 is mounted on the output shaft 221, the first limiting structure 2111 and the second limiting structure 222 can cooperate to prevent the driving wheel 210 from rotating relatively on the output shaft 221, so that the driving wheel 210 can only rotate synchronously with the output shaft 221, the idle rotation of the output shaft 221 is avoided, and the transmission reliability of the driving piece 220, the driving wheel 210 and the washing tub 100 is ensured.

As shown in fig. 5 and 7, a fastener 230 (e.g., a bolt) is provided on the driving wheel 210, and the fastener 230 abuts against an outer wall surface of the output shaft 221 to lock the output shaft 221 and the driving wheel 210. The driving wheel 210 is restrained on the output shaft 221 by the fastener 230, preventing the driving wheel 210 from moving in the axial direction of the output shaft 221 to loosen the driving wheel 210, and improving the reliability of the assembly between the output shaft 221 and the driving wheel 210 and between the driving wheel 210 and the washing tub 100. Moreover, due to the rotation stopping function of the first limiting structure 2111 and the second limiting structure 222, in the installation process, the driving wheel 210 and the output shaft 221 are kept relatively fixed, so that workers can conveniently screw the fastener 230, the situation that the fastener 230 cannot be locked by the fastener 230 and abnormal noise is generated in the operation process due to the fact that the fastener 230 is not locked because the driving wheel 210 and the output shaft 221 rotate relatively in the installation process is avoided, the first limiting structure 2111 and the second limiting structure 222 play a role in preventing fool in the product assembly process, and the installation difficulty of the output shaft 221 and the driving wheel 210 is reduced.

In some embodiments, as shown in fig. 4 and 6, the first limiting structure 2111 includes a non-circular transmission hole 2112 disposed on the driving wheel 210, the output shaft 221 is adapted to the transmission hole 2112, the output shaft 221 is disposed through the transmission hole 2112 to drive the driving wheel 210 to rotate, and a portion of the output shaft 221 penetrating into the transmission hole 2112 is formed as the second limiting structure 222. In this way, the first limiting structure 2111 and the second limiting structure 222 are simple in structural form, the driving wheel 210 is mounted on the output shaft 221, the rotation stopping of the driving wheel 210 and the output shaft 221 is synchronously realized, and the mounting is simpler.

Further, the cross-section of the drive aperture 2112 is semi-circular or horseshoe shaped. The semicircular or horseshoe-shaped transmission hole 2112 is simple in processing technology, convenient for workers to operate, and capable of effectively guaranteeing processing accuracy, and further guaranteeing assembling accuracy between the transmission hole 2112 and the output shaft 221.

For example, as shown in fig. 4, the transmission hole 2112 is a semicircular hole, and in detail, the cross-sectional profile of the transmission hole 2112 includes a straight edge and an arc-shaped edge, and two ends of the arc-shaped edge correspond to two ends of the connecting straight edge, so that the straight edge and the arc-shaped edge surround the semicircular hole. Correspondingly, at least a part of the output shaft 221 is matched with the transmission hole 2112, wherein the cross section of the part matched with the output shaft 221 comprises a straight edge and an arc-shaped edge, and two ends of the arc-shaped edge are correspondingly connected with two ends of the straight edge.

Of course, in other embodiments, the cross section of the transmission hole 2112 may have other shapes, for example, the cross section of the transmission hole 2112 has a square shape, a triangular shape, a special shape, etc., which are not illustrated here, and each of the shapes can play a role in preventing rotation between the transmission hole 2112 and the output shaft 221.

Further, as shown in fig. 4 and 7, the cross section of the portion of the output shaft 221 that extends into the transmission hole 2112 is non-circular and fits into the transmission hole 2112, and the cross section of the portion that does not extend into the transmission hole 2112 is circular. This is more advantageous to effectively transmit the torque of the output shaft 221 while ensuring the rotation stop of the output shaft 221 and the driving wheel 210.

The arrangement of the through hole 2113 facilitates the installation of the fastening member 230, the arrangement of the plane 2211 on the output shaft 221 enables the contact surface between the fastening member 230 and the output shaft 221 to be changed from point contact and line contact to surface contact, the locking force of the fastening member 230 is larger, the situation that the driving wheel 210 is loosened from the output shaft 221 is further prevented, the installation reliability of the driving wheel 210 and the output shaft 221 is improved, and then the generation of abnormal sound is avoided.

For example, the through-hole 2113 is internally threaded, and the fastener 230 is threadedly coupled to the through-hole 2113.

Further, a positioning surface 21121 adapted to the flat surface 2211 is formed on a part of the inner wall surface of the transmission hole 2112, an opening at one end of the through hole 2113 is formed on the positioning surface 21121, and when the output shaft 221 is inserted into the transmission hole 2112, the flat surface 2211 contacts the positioning surface 21121 and is opposite to the through hole 2113. Thus, when the driving wheel 210 is installed on the output shaft 221, the position of the plane 2211 of the output shaft 221 is opposite to the position of the through hole 2113, the process that workers manually align the through hole 2113 and the plane 2211 is omitted, the assembly difficulty is further reduced, the assembly efficiency is improved, meanwhile, the situation that the workers do not align the fastening piece 230 with the plane 2211 of the output shaft 221 due to carelessness is avoided, and the fool-proof effect is achieved.

Further, the axis of the through-hole 2113 is perpendicular to the plane 2211. This facilitates the positioning of the fastener 230 relative to the drive wheel 210, and also facilitates the perpendicular positioning of the fastener 230 relative to the flat surface 2211, so that the contact between the fastener 230 and the flat surface 2211 is stronger, and the drive wheel 210 and the output shaft 221 can be firmly locked by the fastener 230.

In some embodiments, as shown in FIGS. 2 and 5, the driving wheel 210 includes a central portion 211 and an outer ring portion 212, the outer ring portion 212 surrounds the central portion 211 and is connected to the central portion 211, the central portion 211 is provided with a driving hole 2112 and a through hole 2113, and the clothes treating apparatus 10 further includes a driving member drivingly connected to the outer ring portion 212 and the washing tub 100. The central portion 211 is connected to the driving member 220, and the outer ring portion 212 is connected to the washing tub 100 in a driving manner, so that the structure is simple and the driving is reliable.

The transmission members include a transmission belt 240, a transmission hinge, and the like, which are not illustrated herein.

The arrangement of the plurality of blades 213 enables the driving wheel 210 to have a heat dissipation function, and the blades 213 can dissipate heat of the driving part 220 by product airflow while the driving wheel 210 is in rotation transmission, so that the reliability and the safety of the driving part 220 are ensured.

Further, the central portion 211 and the outer ring portion 212 are connected through a plurality of reinforcing ribs, and the reinforcing ribs increase the connection reliability of the central portion 211 and the outer ring portion 212, so that the overall strength of the driving wheel 210 is improved, and the risk of deformation and damage of the driving wheel 210 is reduced. Wherein the plurality of ribs are at least partially formed with blades 213.
