DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below with reference to the attached drawings, which show, by way of example, specific embodiments in which like constituents are referred to with like reference numerals. The embodiments described below are examples for explaining the present application and are not to be understood as limiting the present application.

[0022] A laundry treating apparatus 1 according to embodiments of the present application is described below with reference to FIGS. 1-10.

[0023] As shown in FIGS. 1-2, the laundry treating apparatus 1 according to the present application includes an outer tub 10, a damping structure 20, and a connecting rod 30. The damping structure 20 is hingedly coupled to the outer tub 10 at one end and is configured as a plurality of structures spaced apart from each other. The connecting rod 30 connects at least two of the damping structures 20. The connecting rod 30 includes at least a first rod portion 312 and a second rod portion 311. One end of the first rod portion 312 is connected to the damping structure 20, and the other end of the first rod portion 312 is connected to the second rod portion 311 via a damping member 34. At least portions of the first rod portion 312 and the second rod portion 311 are staggered to form at least one bent structure on the connecting rod 30.

[0024] In some embodiments, the outer tub 10 generates vibration when the laundry treating apparatus 1 is in operation, and the vibration generates noise. The damping structure 20 connected to the outer tub 10 can reduce the vibration amplitude of the outer tub 10, thereby reducing the noise transmitted to the outside of the laundry treating apparatus 1. When there are a plurality of damping structures 20 connected to different positions of the laundry treating apparatus 1, the vibration reduction amplitudes of the damping structures 20 can be different. Therefore, the connecting rod 30 is designed to connect at least two damping structures 20. The connecting rod 30 can balance the vibration between the at least two damping structures 20 connected thereto, and reduce the vibration amplitude of the damping structures 20 connected to the connecting rod 30 relative to the outer tub 10, thereby further reducing the noise transmitted to the outside of the laundry treating apparatus 1 and improving the user experience.

[0025] According to some embodiments of the present application, the connecting rod 30 includes at least a first rod portion 312 and a second rod portion 311. One end of the first rod portion 312 is connected to the damping structure 20, and the other end of the first rod portion 312 is connected to the second rod portion 311 through the damping member 34. At least a portion of the first rod portion 312 and the second rod portion 311 are staggered to form at least one bending structure on the connecting rod 30. Here, at least a portion of the first rod portion 312 and the second rod portion 311 are staggered so that the connecting rod 30 has at least one bending structure, and the axes of the first rod portion 312 and the second rod portion 311 are not collinear. When the connecting rod 30 has a tendency to rotate relative to the outer tub 10, the bending structure can abut against the surface of the outer tub 10 to prevent the connecting rod 30 from rotating relative to the outer tub 10. Alternatively, in some embodiments of the present application, a rotation stopping structure 35 is provided to fix the portion of the connecting rod 30 having the bending structure relative to the outer tub 10. Under the action of the rotation stopping structure 35, the connecting rod 30 can also be prevented from rotating relative to the outer tub 10.

[0026] In addition, the portion where the first rod portion 312 and the second rod portion 311 are connected is also provided with the damping member 34. Such a structure for energy absorption is provided at the connection between the first rod portion 312 and the second rod portion 311 to reduce the fitting stiffness between the first rod portion 312 and the second rod portion 311. In addition, the force between the first rod portion 312 and the second rod portion 311 can be transmitted to the damping member 34, and the compression amount of the damping member 34 also increases, so that the energy absorption and vibration reduction effect of the damping member 34 is better.

[0027] According to the laundry treating apparatus 1 of the present application, the connecting rod 30 is provided to connect at least two damping structures 20, and at least a portion of the first rod portion 312 and the second rod portion 311 of the connecting rod 30 are staggered to prevent the connecting rod 30 from rotating relative to the outer tub 10, reduce the vibration of the connecting rod 30, and thereby reduce the noise generated by the connecting rod 30 when the laundry treating apparatus 1 is in operation, and improve the user experience.

[0028] According to some embodiments of the present application, as shown in FIG. 2, the other end of the first rod portion 312 is movably coupled with the second rod portion 311 to balance the vibration of the two damping structures 20. Here, the other end of the first rod portion 312 is provided with a damping member 34, which can attenuate the vibration between the first rod portion 312 and the second rod portion 311, and the force transmitted to each other by the first rod portion 312 and the second rod portion 311 is absorbed by the damping member 34. The damping member 34 can ensure the connection stability of the first rod portion 312 and the second rod portion 311, reduce the probability of vibration of the first rod portion 312 and the second rod portion 311 due to relative movement, and further reduce the noise generated by the connection of the first rod portion 312 and the second rod portion 311.

[0029] According to some embodiments of the present application, as shown in FIG. 4, the second rod portion 311 includes a first rod body 3111 movably coupled with the other end of the first rod portion 312, and a first bent rod 3112 connected with the first rod body 3111 and staggered with the first rod portion 312. Here, the first bent rod 3112 of the second rod portion 311 is staggered with the first rod portion 312, and the first rod body 3111 of the second rod portion 311 is movably coupled with the first rod portion 312. In some embodiments, the first rod body 3111 is arranged in line with the first rod portion 312.

[0030] According to some embodiments of the present application, as shown in FIG. 4, the first rod body 3111 and the first rod portion 312 both extend in the first direction, the first rod body 3111 has a mounting channel 311a extending in the first direction formed therein, the other end of the first rod portion 312 is slidably received in the mounting channel 311a, and at least part of the damping member 34 is located between the mounting channel 311a and the first rod portion 312. Here, since the outer cylinder 10 will sink after the load is added, the relative positions of the two damping structures 20 will change. In order to ensure that the connecting rod 30 in the middle is not pulled, the connecting rod 30 needs to include at least two sections that can move relative to each other. The first rod body 3111 is designed to have a mounting channel 311a extending in the first direction formed therein, so that the first rod portion 312 can move in the first direction after being arranged in the mounting channel 311a, avoiding the connecting rod 30 being pulled. At the same time, the force transmitted to each other by the first rod portion 312 and the inner wall surface of the mounting channel 311a is absorbed by the damping member 34, and the damping member 34 can ensure the connection stability of the first rod portion 312 and the first rod body 3111.

[0031] According to some embodiments of the present application, as shown in FIG. 5, the damping member 34 is sleeved on the other end of the first rod portion 312; at least one end of the damping member 34 is formed with a flange 341 protruding from the outer surface of the damping member 34, the projection of the damping member 34 in the first direction is within the projection of the flange 341 in the first direction, and the flange 341 is adapted to abut against the end of the first rod body 3111 formed with the mounting channel 311a to limit the displacement amount of the relative movement between the first rod body 3111 and the first rod portion 312, thereby avoiding the disengagement of the first rod portion 312 from the mounting channel 311a of the first rod body 3111. It can be understood that when the outer cylinder 10 vibrates, the first rod portion 312 and the first rod body 3111 move relatively, and the design of the flange 341 on the damping member 34 can provide a displacement allowance for the movable connection between the first rod portion 312 and the first rod body 3111 while avoiding the disengagement of the first rod portion 312 from the first rod body 3111, thereby avoiding the breakage of the first rod portion 312 and the first rod body 3111 due to excessive force when the first rod portion 312 and the first rod body 3111 move relatively.

[0033] The arrangement of the first rod body 3111, the first bent rod 3112 and the second rod body 3113 makes the second rod portion 311 have at least one bending structure, and the axes of the first rod body 3111, the first bent rod 3112 and the second rod body 3113 are not collinear, which can avoid the rotation of the second rod portion 311 relative to the outer cylinder 10 after the fixed connection of the second rod portion 311 and the outer cylinder 10.

[0034] According to some embodiments of the present application, the laundry treating apparatus 1 further comprises a rotation-stopping structure 35, which is arranged on one of the first rod portion 312 and the second rod portion 311, and is adapted to be connected with the outer tub 10 to limit the rotation of the connecting rod 30 relative to the outer tub 10; wherein the rotation-stopping structure 35 is formed with a recess 3531a adapted to accommodate the first rod portion 312 or the second rod portion 311.

Similarly, the lengths of the two first rod bodies 3111, the lengths of the two second rod bodies 3113 and the lengths of the two second bent rods 3114 can be the same or different, and can be designed according to actual needs. In addition, the lengths of the first rod body 3111, the first bent rod 3112, the second rod body 3113, the second bent rod 3114 and the third rod body 3115 can be the same or different, and by designing the lengths of different rods and the positions of the stop structure 35, the connection stiffness between the second rod portion 311 and the outer cylinder 10 can be adjusted.

[0038] According to some embodiments of the present application, as shown in FIG. 10, the stop structure 35 is formed with a groove 3531a adapted to accommodate the first rod portion 312 or the second rod portion 311. Here, the stop structure 35 is adapted to be fixedly connected with the outer cylinder 10 to connect the second rod portion 311 with the outer cylinder 10. Of course, the connection between the second rod portion 311 and the outer cylinder 10 can be that the second rod portion 311 is directly fixed on the outer cylinder 10, or that the second rod portion 311 is fixed on the outer cylinder 10 through the stop structure 35, and the second rod portion 311 cooperates with the groove 3531a formed on the stop structure 35.

[0039] In some embodiments, the stop structure 35 is formed with a protruding portion 3531 protruding towards one side, and the groove 3531a is formed on the other side of the stop structure 35, and the groove 3531a is adapted to accommodate the second rod portion 311.

The buffer 36 is adapted to attenuate the vibration between the rotation-stopping structure 35 and the connecting rod 30. In some embodiments, the buffer 36 can be sleeved on at least part of the outer periphery of the connecting rod 30. When the outer drum 10 vibrates, the connecting rod 30 can move relative to the rotation-stopping structure 35, resulting in vibration between the rotation-stopping structure 35 and the connecting rod 30. At this time, the buffer 36 can buffer the vibration between the rotation-stopping structure 35 and the connecting rod 30, thereby attenuating the vibration between the outer drum 10 and the connecting rod 30.

[0042] In some embodiments, the first rod portion 312 includes a connecting rod portion 3121 and a first buffer structure 32.

The fixing member 33 penetrates the first mounting hole 221a and the second mounting hole 32a to connect the connecting portion 221 and the first buffer structure 32.

[0044] In the above embodiments, the end of the first rod portion 312 connected to the damping structure 20 is provided with the first buffering structure 32, the portion of the second rod portion 311 connected to the first rod portion 312 is provided with the damping member 34, and the portion of the second rod portion 311 connected to the connecting portion 221 of the outer cylinder 10 is provided with the buffering member 36.

[0045] In some embodiments, the performance of the energy-absorbing structure needs to meet that, at a position where the rod body 31 is subjected to a vibration of a constant frequency, the damping factor of the energy-absorbing structure is greater than or equal to 0.8.

[0046] In some embodiments, the damping structure 20 comprises a support rod 21 and a connecting portion 221, one end of the support rod 21 is hingedly connected to the outer cylinder 10, and the connecting portion 221 is arranged on the support rod 21 and is adapted to be connected to the first rod portion 312.

[0047] In some embodiments, the damping structure 20 further comprises a sleeve 22, the sleeve 22 is sleeved on the outer periphery of the support rod 21, the connecting portion 221 is arranged on the sleeve 22, and the sleeve 22 is adapted to rub against the outer periphery of the support rod 21 to attenuate the vibration transmitted between the support rod 21 and the sleeve 22.

[0048] According to some embodiments of the present application, at least one of the first rod body 3111, the first bent rod 3112, and the second rod body 3113 is adapted to be fixedly connected to the outer cylinder 10. Here, the connection between the second rod portion 311 and the outer cylinder 10 can be that the second rod portion 311 is directly fixed on the outer cylinder 10, or that the second rod portion 311 is fixed on the outer cylinder 10 through the rotation-stopping structure 35, and the second rod portion 311 cooperates with the groove 3531a formed on the rotation-stopping structure 35.

The first mounting hole 221a and the connecting passage 3121a have the same shape, the shape of the fixing member 33 is adapted to the shape of the first mounting hole 221a, and the first mounting hole 221a is configured as a non-circular hole. When the connecting portion 221 and the connecting rod portion 3121 have a relative rotation trend, the fixing member 33 will abut against the hole wall of the first mounting hole 221a and the connecting passage 3121a, limiting the relative rotation between the connecting portion 221 and the connecting rod portion 3121, and transmitting the force to the connecting rod portion 3121, so that the connecting rod portion 3121 attenuates the force transmitted to the connecting rod 30, thereby ensuring the connection stability of the connecting portion 221 and the connecting rod portion 3121, reducing the probability of vibration of the connecting portion 221 and the connecting rod portion 3121 due to relative movement, and further reducing the noise generated by the connection of the connecting portion 221 and the connecting rod portion 3121.

Here, since the support rods 21 are hingedly connected to the outer cylinder 10, the outer cylinder 10 will sink after being loaded, and the relative positions of the support rods 21 on both sides will change. In order to ensure that the rod body 31 in the middle is not pulled, the rod body 31 needs to include at least two sections that can move relative to each other. The second rod portion 311 is designed to have mounting passages 311a extending in the first direction at both ends, so that the first rod portion 312 can move in the first direction after being arranged in the mounting passage 311a, thereby avoiding the rod body 31 from being pulled.

[0073] It can be understood that, since the connecting rod 30 is fixedly connected with the outer cylinder 10, when the outer cylinder 10 vibrates, relative movement exists between the connecting rod 30 and the support rod 21. In order to avoid the connecting rod 30 or the support rod 21 from being broken due to excessive force caused by the relative movement between the connecting rod 30 and the support rod 21, the rod body 31 of the connecting rod 30 is designed as a multi-rod segment structure that can move relatively.

[0074] According to the laundry treating apparatus of the present application, the connecting rod 30 is arranged to connect at least two vibration reduction structures 20, and the connecting rod 30 can balance the vibration between the at least two vibration reduction structures 20 connected therewith, thereby reducing the vibration noise. Meanwhile, the connecting rod 30 includes at least two segments that can move relatively. The second rod part 311 is designed to form an installation channel 311a, so that the first rod part 312 can move after being arranged in the installation channel 311a, thereby avoiding the rod body 31 from being pulled. The design of the second rod part 311 and the first rod part 312 can provide displacement allowance for the connection between the connecting rod 30 and the vibration reduction structure 20, thereby avoiding the connecting rod 30 or the support rod 21 from being broken due to excessive force caused by the relative movement between the connecting rod 30 and the vibration reduction structure 20.

[0076] According to some embodiments of the present application, the connecting rod 30 is fixedly connected with the outer cylinder 10, so as to limit the movement of the connecting rod 30 relative to the outer cylinder 10. The connecting rod 30 can connect at least two vibration reduction structures 20 with the outer cylinder 10. By increasing the connection between the at least two vibration reduction structures 20, the rigidity between the vibration reduction structures 20 can be improved, and the connecting rod 30 can balance the vibration between the at least two vibration reduction structures 20 connected therewith, thereby reducing the eccentricity of the outer cylinder 10, and thus reducing the vibration noise. Meanwhile, by the connection between the connecting rod 30 and the outer cylinder 10, the vibration amplitude of the vibration reduction structure 20 connected with the connecting rod 30 relative to the outer cylinder 10 can be reduced, thereby further reducing the vibration noise and improving the user experience.
