[0047] For the existing drum washing machine, the bearing seat and the outer cylinder body are fixed together by encapsulation process.

[0048] However, this mounting method will cause the vibration of the rotating shaft of the inner cylinder to be directly transmitted to the outer cylinder body through the bearing seat, thereby causing the outer cylinder body to produce relatively large vibration. The relatively large vibration of the outer cylinder body will produce relatively large sound radiation, and the parts connected to the outer cylinder body are prone to looseness or fatigue failure due to long-term forced vibration.

[0049] Moreover, the existing drum washing machine requires the outer cylinder body to directly bear the force of the damper, so the strength requirement of the outer cylinder body is relatively high. Designers will design more ribs on the outer cylinder body to improve the strength in order to meet the strength requirement of the outer cylinder body. However, the increase of the ribs will increase the process difficulty and the sound radiation area of the outer cylinder body. The increase of the process difficulty will increase the production cost, and the sound radiation will produce noise and affect the user experience.

[0050] Based on this, as shown in the drawings, the clothes processing device according to the embodiment of the present application comprises: Figures 1-5 an outer cylinder assembly 2 comprising an outer cylinder body 21, the rear wall of the outer cylinder body 21 having a mounting hole;

[0051] an inner cylinder assembly 3 comprising an inner cylinder body 31 and an inner cylinder rotating shaft 33 connected to the inner cylinder body 31;

[0052] The mounting frame 6 includes a first support 61 fixedly connected and located below the outer cylinder barrel 21 for supporting the outer cylinder barrel 21, and a second support 62 located above one side of the first support 61 and behind the outer cylinder barrel 21;

[0053] The bearing seat 32 is fixed on the second support 62, the mounting hole of the outer cylinder barrel 21 is sleeved on the support seat, and the rear wall of the outer cylinder barrel 21 is flexibly and sealingly connected with the bearing seat 32;

[0054] The inner cylinder rotating shaft 33 passes through the bearing seat 32, which is arranged to be supported by the bearing seat 32 and rotatable relative to the bearing seat 32, so that the inner cylinder barrel 31 is rotatable relative to the outer cylinder barrel 21.

[0055] Specifically, the front side of the clothes treatment device is the side for putting clothes, and the back side of the clothes treatment device is opposite to the front side and generally used for the side close to the wall surface.

[0056] The outer cylinder barrel 21 is arranged in the cabinet 1, the inner cylinder barrel 31 is arranged in the outer cylinder barrel 21, the bearing seat 32 arranged at the back side of the inner cylinder can be connected with the driving motor, the stator of the driving motor is fixed on the bearing seat 32 by screws, the rotor of the driving motor is connected with the rotating shaft 33 of the inner cylinder by spline connection, and a thread is arranged at the rear end of the rotating shaft 33 of the inner cylinder, so that the rotor of the motor is locked with the rotating shaft 33 of the inner cylinder by cooperation of the nut and the thread, so that the driving motor can drive the inner cylinder barrel 31, and the bearing in the bearing seat 32 can also limit the rotating shaft 33 of the inner cylinder to a certain extent.

[0057] The bearing seat 32 can pass through the rear part of the outer cylinder barrel 21 through the mounting hole at the rear part of the outer cylinder barrel 21, the diameter of the mounting hole is greater than the outer diameter of the bearing seat 32, and there is a gap between the hole wall of the mounting hole and the outer periphery of the bearing seat 32, so that the bearing seat 32 is no longer in direct contact with the outer cylinder barrel 21, and the vibration of the rotating shaft 33 of the inner cylinder can be avoided from being directly transmitted to the outer cylinder barrel 21 through the bearing seat 32, so that the outer cylinder barrel 21 does not vibrate greatly, the vibration not only produces a large noise, but also causes fatigue failure of other parts fixedly connected with the outer cylinder barrel 21 due to long-term large vibration, or loosening of the connection between the outer cylinder barrel 21 and the other parts, and falling.

[0058] Moreover, the bearing seat 32 and the outer cylinder barrel 21 are connected by flexible sealing according to the application, and the sealing and fixing by the encapsulation process is no longer used, so that the part of the bearing seat located behind the outer cylinder barrel 21 can be exposed to the air, the heat dissipation of the bearing seat can be more convenient, the temperature of the bearing seat is reduced, and the service life and vibration performance of the bearing are beneficial.

[0059] According to the laundry treating device, the bearing seat 32 can pass through the rear part of the outer cylinder barrel 21 through the mounting hole in the rear part of the outer cylinder barrel 21, a gap is reserved between the hole wall of the mounting hole and the outer periphery of the bearing seat 32, and the gap is sealed by the flexible sealing piece 4, so that the bearing seat 32 and the outer cylinder barrel 21 are no longer connected in a sealing and fixed manner by the encapsulation process, but are connected in a relatively flexible manner, thereby realizing the flexible connection between the inner cylinder and the outer cylinder barrel 21, the outer cylinder barrel 21 is connected with the first support 61, and the bearing seat 32 is connected with the second support 62, so that the mounting frame 6 can support the outer cylinder barrel 21 and the bearing seat 32 respectively, the bearing seat 32 can no longer be in direct contact with the outer cylinder barrel 21, the vibration of the rotating shaft 33 of the inner cylinder can be avoided from being directly transmitted to the outer cylinder barrel 21 through the bearing seat 32, and the outer cylinder barrel 21 can be prevented from generating large vibration, the vibration not only generates large noise, but also causes other components fixedly connected with the outer cylinder barrel 21 to be fatigue failed due to long-term large vibration, or the connection between the other components and the outer cylinder barrel 21 to be loosened and dropped.

[0060] Optionally, in an implementation manner of the embodiment, the gap is provided between the outer periphery of the bearing seat 32 and the mounting hole, and the flexible sealing piece 4 is arranged in the gap to realize the flexible and sealed connection between the rear wall of the outer cylinder barrel 21 and the bearing seat 32.

[0061] Optionally, in an implementation manner of the embodiment, the gap distance of the gap is greater than the maximum vibration offset of the bearing seat 32.

[0062] Specifically, the gap can be a circular annular gap surrounding the outer periphery of the bearing seat 32, and the gap distance of the gap is the ring width of the circular annular gap. The bearing seat 32 generates a certain vibration when rotating with the inner cylinder barrel 31, and the maximum vibration offset is the maximum offset distance of the bearing seat 32 when vibrating. The ring width is greater than the maximum vibration offset generated by the vibration, so as to avoid the bearing seat 32 from colliding with the outer cylinder barrel 21.

[0063] Optionally, in an implementation manner of the embodiment, the laundry treating device further comprises:

[0064] the box 1, the bottom of the box 1 has a base 101, the mounting frame 6 is arranged in the box 1, and the outer cylinder assembly 2 is arranged in the box 1;

[0065] the tension spring 5, one end of the tension spring 5 is connected with the top of the outer cylinder barrel 21, and the other end of the tension spring 5 is connected with the box 1;

[0066] the damper 7, one end of the damper 7 is connected with the bottom of the mounting frame 6, and the other end of the damper 7 is connected with the base 101.

[0067] Specifically, the number of the tension spring 5 can be four, and one can be arranged at each of the four corners of the top of the outer cylinder barrel 21. The top of the outer cylinder barrel 21 is connected to the top of the box body 1 through the tension spring 5, the bottom of the outer cylinder barrel 21 is connected to the mounting frame 6, the mounting frame 6 is connected to the base 101 of the box body 1 through the damper 7, and the number of the damper 7 can be four, and one can be arranged at each of the four corners of the mounting frame 6. The inner cylinder barrel 31 of the inner cylinder is arranged inside the outer cylinder barrel 21, the mounting seat extends from the mounting hole at the rear of the outer cylinder barrel 21, and then is connected to the mounting frame 6. The vibration of the inner cylinder bearing seat 32 can be transmitted to the mounting frame 6, and then the vibration of the mounting frame 6 is absorbed through the damper 7, so that the vibration is avoided from being transmitted to the ground.

[0068] Optionally, in an implementation manner of the embodiment, a damping and limiting component is arranged between the mounting frame 6 and the outer cylinder barrel 21, and the damping and limiting component has a thrust force acting on the mounting frame 6 and the outer cylinder barrel 21 along the axial direction of the outer cylinder barrel 21.

[0069] The thrust force of the damping and limiting mechanism increases with the increase of the compression amount of the damping and limiting mechanism, and the increase speed of the thrust force is greater than the increase speed of the compression amount.

[0070] Specifically, since the inner cylinder and the outer cylinder barrel 21 are fixed on the mounting frame 6, part of the vibration generated by the bearing seat 32 of the inner cylinder is also transmitted to the outer cylinder barrel 21 from the mounting frame 6. Through the damping and limiting component, the vibration transmitted to the outer cylinder barrel 21 from the mounting frame 6 can be absorbed, and the vibration transmitted to the outer cylinder barrel 21 from the mounting frame 6 is reduced.

[0071] Moreover, the increase speed of the thrust force of the damping and limiting mechanism is greater than the increase speed of the compression amount, so that when the damping mechanism is compressed to a certain value, the damping and limiting mechanism can play a certain limiting role when the vibration of the mounting frame 6 is large, thereby avoiding that the outer cylinder barrel 21 vibrates greatly with the mounting frame 6, and causing the outer cylinder barrel 21 to collide with the inner cylinder.

[0072] Optionally, in an implementation manner of the embodiment, the limiting component is a bushing 8 extending along the axial direction of the outer cylinder barrel 21, and the two ends of the bushing 8 along the axial direction of the outer cylinder barrel 21 are connected to the outer cylinder barrel 21 and the mounting frame 6 respectively.

[0073] Or the limiting component is a conical spring extending along the axial direction of the outer cylinder barrel 21, and the two ends of the conical spring along the axial direction of the outer cylinder barrel 21 are connected to the outer cylinder barrel 21 and the mounting frame 6 respectively.

[0074] Optionally, in an implementation manner of the embodiment, a support connecting seat 9 is arranged above the first support 61.

[0075] The bottom of the support connecting seat 9 is connected with the first support 61, and the top of the support connecting seat 9 has a mounting block 901 extending along the axial direction of the outer cylinder barrel 21, one end of the bushing 8 in the axial direction of the outer cylinder barrel 21 is connected with the mounting block 901, and the other end is connected with the outer cylinder barrel 21.

[0076] Specifically, the outer cylinder barrel 21 can be provided with a reinforcing rib or a mounting structure at a position corresponding to the bushing 8, and is fixedly connected with the bushing 8. The bushing 8 can be connected with the support connecting seat 9, so that the bushing 8 can extend in the axial direction, that is, in the same direction as the outer cylinder barrel 21, thereby sufficiently reducing the vibration transmitted from the mounting frame 6 to the outer cylinder barrel 21, limiting the outer cylinder barrel 21, and avoiding collision between the outer cylinder barrel 21 and the inner cylinder barrel 31.

[0077] When the relative vibration between the inner cylinder barrel 31 and the outer cylinder barrel 21 is large, the nonlinear stiffness of the bushing 8 increases sharply, which can play a limiting role. The stiffness and deformability of the bushing 8 are designed according to the minimum distance between the inner cylinder and the outer cylinder; the thrust increases with the increase of the compression amount of the damping and limiting mechanism, and the increase speed of the thrust is greater than the increase speed of the compression amount, that is, with the increase of the compression amount of the bushing 8, the nonlinear stiffness of the bushing 8 is fully utilized, and the relative displacement between the inner cylinder barrel 31 and the outer cylinder barrel 31 is limited, thereby playing a limiting protection role.

[0078] In addition, the rubber will produce a certain plastic deformation under a large impact, but still has elastic recovery ability. Since the nut is used for pre-tightening the bushing 8 during installation, the deformation amount of the bushing 8 during pre-tightening can compensate for the plastic deformation amount under a large impact, so that the bushing 8 will not loosen after impact in a static state. Large impact conditions are extremely rare, and the limiting role here is to prevent accidents.

[0079] Optionally, in an implementation manner of the embodiment, the clothes treatment apparatus further includes:

[0080] The second support 62 has a top connected with the bearing seat 32 and a bottom connected with the mounting frame 6.

[0081] The top of the second support 62 has an arc surface matched with the bottom of the bearing seat 32, and the second support 62 is connected with the bottom of the bearing seat 32 through the arc surface.

[0082] Specifically, the second support 62 can connect the bearing seat 32 and the mounting frame 6. The second support 62 is connected with the bearing seat 32 through the arc surface, which can increase the contact area with the bearing seat 32 and improve the fixing strength. The bottom of the second support 62 can be a plate body, and then the rear part of the mounting frame 6 is also bent upward to form a plate body, which is connected with the plate body through the plate body, thereby improving the connection reliability.

[0083] Optionally, in an implementation form of the embodiment, the flexible seal 4 is made of rubber, and has a circular ring structure, and the inner and outer rings are detachably and sealingly connected with the bearing seat 32 and the mounting hole of the outer cylinder barrel 21 respectively.

[0084] Specifically, the flexible seal 4 can be made of rubber, and can not only seal the gap, but also support the bearing seat 32 to some extent, and can also reduce the vibration of the bearing seat 32 transmitted to the outer cylinder barrel 21 through its own elasticity.

[0085] The detachable flexible seal 4 can facilitate after-sales maintenance. When cleaning is needed, the flexible seal 4 can be detached to extend into the outer cylinder barrel 21 from the gap for cleaning.

[0086] Optionally, in an implementation form of the embodiment, the outer periphery of the bearing seat 32 is provided with a mounting protrusion 3201, the inner ring of the flexible seal 4 is sleeved on the mounting protrusion 3201, and the outer ring of the flexible seal 4 is interference fit with the mounting hole of the outer cylinder barrel 21.

[0087] Specifically, the dismounting structure can be realized by sleeving the mounting protrusion 3201 and interference fit with the mounting hole of the outer cylinder barrel 21. When the inner ring of the flexible seal 4 is sleeved on the circumferential mounting protrusion 3201 of the bearing seat 32, a waterproof coating can be applied to prevent leakage. When the outer ring of the flexible seal 4 is interference fit with the mounting hole of the outer cylinder barrel 21, a waterproof coating can also be applied to achieve better sealing effect.

[0088] Optionally, in an implementation form of the embodiment, the inner ring of the flexible seal 4 has an inner ring part matched with the bearing seat 32 and an outer ring part matched with the mounting hole of the outer cylinder barrel 21.

[0089] The inner ring part and the outer ring part are subjected to hardening treatment.

[0090] Specifically, the inner ring part of the flexible seal 4 can be a part with a ring thickness of 2mm to 5mm starting from the inner wall of the inner ring, and the outer ring part of the flexible seal 4 can be a part with a ring thickness of 2mm to 5mm starting from the outer wall of the outer ring. Through hardening treatment, the flexible seal 4 can better assemble and sealingly cooperate with the outer periphery of the bearing seat 32 and the mounting hole of the outer cylinder barrel 21.

[0091] Optionally, in an implementation form of the embodiment, the flexible seal 4 further comprises:

[0092] an intermediate part located in front of the inner ring part and the outer ring part;

[0093] The intermediate part has a plurality of annular wrinkles.

[0094] Specifically, in addition to the hardened portion described above, the remaining portion can be designed with a fold, which can be an annular corrugated structure centered on the center of the flexible seal 4, which can be similar to a bellows structure. The annular fold can make the flexible seal 4 have better vibration absorption performance, and can further reduce the vibration transmitted from the bearing seat 32 to the outer cylinder barrel 21.

[0095] Specifically, in the assembly process:

[0096] The outer cylinder barrel 21 can be connected to the mounting frame 6 by bolts. After the outer cylinder barrel 21 is connected to the mounting frame 6, the top is connected to the box body 1 by a hanging spring, the bearing is interference-fitted with the bearing seat 32, the bearing is pressed into the bearing seat 32 by a hydraulic machine, and the bearing seat 32 is connected to the mounting frame 6 through the second support 62. The inner ring of the flexible seal 4 is embedded on the bearing seat 32, the embedded part is coated with sealant, the outer ring is interference-fitted with the mounting hole of the outer cylinder barrel 21 and is connected, and a hammer or a hydraulic machine is used for installation. After the outer cylinder barrel 21 is connected, the outer ring of the rubber seal is also coated with a layer of sealant.
