Description

Technical Field

[0001] The present application relates to the technical field of clothing processing devices, and in particular, to a clothing processing device. Background Art

[0002] For the existing drum washing machine, the bearing seat and the outer drum body are coated with rubber to fix the inner drum and the outer drum body together.

[0003] However, this installation method will cause the vibration of the inner cylinder's rotating shaft to be directly transmitted from the bearing seat to the outer cylinder body, which will in turn cause the outer cylinder body to vibrate greatly. The large vibration of the outer cylinder body will produce large sound radiation, and the parts connected to the outer cylinder body are in large forced vibration for a long time, and the connection of the parts is prone to loosening or fatigue failure. Summary of the invention

[0004] The embodiment of the present application provides a clothing processing device to at least solve the technical problem that the vibration of the drum shaft is directly transmitted from the bearing seat to the outer drum body, thereby causing the outer drum body to generate greater vibration.

[0005] According to a first aspect of an embodiment of the present application, a clothing discharging device is provided, the clothing processing device comprising: an outer drum assembly, comprising an outer drum body, a rear wall of the outer drum body having a mounting hole;

[0006] An inner cylinder assembly, comprising an inner cylinder body and an inner cylinder rotating shaft connected to the inner cylinder body;

[0007] The mounting frame comprises a first bracket and a second bracket which are fixedly connected, wherein the first bracket is located below the outer cylinder body and is used to support the outer cylinder body, and the second bracket is located above one side of the first bracket and behind the outer cylinder body;

[0008] A bearing seat, which is fixed on the second bracket, the mounting hole of the outer cylinder body is sleeved on the support seat, and the rear wall of the outer cylinder body is flexibly and sealedly connected to the bearing seat;

[0009] The inner cylinder rotating shaft passes through the bearing seat, and is configured to be supported by the bearing seat and rotatable relative to the bearing seat, so that the inner cylinder body is rotatable relative to the outer cylinder body.

[0010] In combination with the first aspect, in an optional implementation of the embodiment of the present application, there is a gap between the outer periphery of the bearing seat and the mounting hole, and a flexible seal is arranged in the gap to achieve a flexible and sealed connection between the rear wall of the outer cylinder body and the bearing seat.

[0011] By adopting this embodiment, it is possible to pass through the rear of the outer cylinder body through the mounting hole at the rear of the outer cylinder body, reserve a certain gap between the hole wall of the mounting hole and the outer periphery of the bearing seat, and then seal the gap with a flexible sealing member, so that the bearing seat and the outer cylinder body are no longer fixedly connected, but a relatively flexible connection method, thereby realizing a flexible connection between the inner cylinder and the outer cylinder body, so that the bearing seat is no longer in direct contact with the outer cylinder body, and the vibration of the rotating shaft of the inner cylinder can be avoided from being directly transmitted from the bearing seat to the outer cylinder body, resulting in greater vibration of the outer cylinder body.

[0012] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the gap distance of the gap is greater than the maximum vibration offset of the bearing seat.

[0013] By adopting this implementation method, collision between the bearing seat and the outer cylinder body can be avoided.

[0014] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the top of the second bracket has an arc-shaped surface adapted to the bottom of the bearing seat, and the second bracket is connected to the bottom of the bearing seat through the arc-shaped surface.

[0015] By adopting this implementation method, the second bracket can connect the bearing seat and the mounting frame. The second bracket is connected to the bearing seat through an arc surface, which can increase the contact area with the bearing seat and improve the fixing strength. The bottom of the second bracket can be a plate body, and then it is also bent upward from the rear of the mounting frame to form a plate body, which is connected to the plate body through the plate body to improve the connection reliability.

[0016] By adopting this implementation, the vibration of the inner cylinder bearing seat can be transmitted to the mounting frame, and then the vibration of the mounting frame is absorbed by the damper to prevent the vibration from being completely transmitted to the ground.

[0017] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the clothing processing device further includes: a bushing;

[0018] The bushing extends along the axial direction of the outer cylinder body, and the two ends of the bushing along the axial direction of the outer cylinder body are respectively connected to the outer cylinder body and the mounting frame, and the bushing has thrusts acting on the mounting frame and the outer cylinder body respectively;

[0019] The thrust of the bushing increases with the increase of the compression amount of the vibration damping and limiting mechanism, and the increasing speed of the thrust is greater than the increasing speed of the compression amount.

[0020] By adopting this implementation mode, the vibration that is about to be transmitted from the mounting frame to the outer cylinder body can be absorbed by the shock-absorbing and limiting component, thereby reducing the vibration transmitted from the mounting frame to the outer cylinder body.

[0021] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the flexible seal is made of rubber material, and the flexible seal is in a circular ring structure, and its inner ring and outer ring are respectively detachably sealed and connected to the mounting holes of the bearing seat and the outer cylinder body.

[0022] The present implementation not only seals the gap, but also reduces the vibration transmitted from the bearing seat to the outer cylinder body through its own elasticity.

[0023] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the outer ring of the bearing seat is provided with a mounting protrusion, the inner ring of the flexible seal is sleeved on the mounting protrusion, and the outer ring of the flexible seal is interference fit with the mounting hole of the outer cylinder body.

[0024] By adopting this implementation method, the disassembly and assembly structure can be realized by sleeve-mounting the installation protrusion and interference fit with the installation hole of the outer cylinder body. When the inner ring of the flexible seal is sleeved on the circumferential installation protrusion of the bearing seat, a waterproof coating can be applied to prevent leakage. When the outer ring of the flexible seal is interference fit with the installation hole of the outer cylinder body, a waterproof coating is also applied, which can achieve a better sealing effect.

[0025] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the inner ring of the flexible seal has an inner ring portion that cooperates with the bearing seat, and an outer ring portion that cooperates with the mounting hole of the outer cylinder body;

[0026] Wherein, the inner ring part and the outer ring part are hardened.

[0027] By adopting this implementation method, through hardening treatment, the flexible seal can be better assembled with the outer periphery of the bearing seat and the mounting holes of the outer cylinder body, and seal in cooperation.

[0028] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the flexible seal further includes:

[0029] a middle portion located between the inner ring portion and the outer ring portion;

[0030] The middle portion has a plurality of annular folds.

[0031] By adopting this implementation, the annular folds can make the flexible seal have better vibration absorption performance, and can further reduce the vibration of the bearing seat transmitted from the flexible seal to the outer cylinder body.

[0032] According to the clothing processing device of the embodiment of the present invention, the bearing seat can pass through the rear part of the outer cylinder body through the mounting hole at the rear part of the outer cylinder body, and a certain gap is reserved between the hole wall of the mounting hole and the outer periphery of the bearing seat, and then the gap is sealed by a flexible sealing member, so that the bearing seat and the outer cylinder body are no longer sealed and fixedly connected by a rubber encapsulation process, but a relatively flexible connection method is used, thereby realizing a flexible connection between the inner cylinder and the outer cylinder body, and then the outer cylinder body is connected to the first bracket, and the bearing seat is connected to the second bracket, so that the mounting frame can support the outer cylinder body and the bearing seat respectively, so that the bearing seat is no longer in direct contact with the outer cylinder body, and the vibration of the rotating shaft of the inner cylinder can be prevented from being directly transmitted from the bearing seat to the outer cylinder body, resulting in a large vibration of the outer cylinder body, which will not only generate a large noise, but also cause other components fixedly connected to the outer cylinder body to fail due to fatigue due to long-term and large vibration, or the connection with the outer cylinder body to loosen and fall off.

[0047] For the existing drum washing machine, the bearing seat and the outer drum body are coated with rubber to fix the inner drum and the outer drum body together.

[0048] However, this installation method will cause the vibration of the inner cylinder's rotating shaft to be directly transmitted from the bearing seat to the outer cylinder body, which will in turn cause the outer cylinder body to vibrate greatly. The large vibration of the outer cylinder body will produce large sound radiation, and the parts connected to the outer cylinder body are in large forced vibration for a long time, and the connection of the parts is prone to loosening or fatigue failure.

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

[0050] Based on this, Figure 1-Figure 5 As shown, the laundry processing device according to the embodiment of the present invention comprises: an outer drum assembly 2, which comprises an outer drum body 21, and the rear wall of the outer drum body 21 has a mounting hole;

[0051] The inner cylinder assembly 3 comprises 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 bracket 61 and a second bracket 62 that are fixedly connected. The first bracket 61 is located below the outer cylinder body 21 and is used to support the outer cylinder body 21. The second bracket 62 is located above one side of the first bracket 61 and behind the outer cylinder body 21.

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

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

[0055] Specifically, the front side of the clothes processing device is a side facing and used for placing clothes, and the rear side of the clothes processing device is a side opposite to the front side, which is generally used for a side close to a wall.

[0056] The outer cylinder body 21 is arranged in the box body 1, and the inner cylinder body 31 is arranged in the outer cylinder body 21. The bearing seat 32 arranged on the rear side of the inner cylinder can be connected to the driving motor. The stator of the driving motor is fixed on the bearing seat 32 by screws. The rotor of the driving motor passes through the bearing seat 32 and is spline-connected with the rotating shaft 33 of the inner cylinder. A thread is arranged at the rear end of the rotating shaft 33 of the inner cylinder. The motor rotor and the rotating shaft 33 of the inner cylinder are locked by the cooperation of the nut and the thread, so that the driving motor can drive the inner cylinder body 31. At the same time, the bearing in the bearing seat 32 can also play a certain limiting function on the rotating shaft 33 of the inner cylinder.

[0057] The bearing seat 32 can pass through the rear part of the outer cylinder body 21 through the mounting hole at the rear part of the outer cylinder body 21. The diameter of the mounting hole is larger 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 body 21, and the vibration of the rotating shaft 33 of the inner cylinder can be prevented from being directly transmitted from the bearing seat 32 to the outer cylinder body 21, causing the outer cylinder body 21 to generate large vibrations. The vibration will not only generate large noise, but also cause other parts fixedly connected to the outer cylinder body 21 to produce fatigue failure due to long-term and large vibrations, or the connection with the outer cylinder body 21 to become loose and fall off.

[0058] Moreover, since the bearing seat 32 proposed in the present application is connected to the outer cylinder body 21 through a flexible seal, the rubber encapsulation process is no longer used for sealing and fixing. The part of the bearing seat located behind the outer cylinder body 21 can also be exposed to the air, which can make it easier for the bearing seat to dissipate heat, reduce the temperature of the bearing seat, and be beneficial to the bearing life and vibration performance.

[0059] According to the clothing processing device of the embodiment of the present invention, the bearing seat 32 can pass through the rear of the outer cylinder body 21 through the mounting hole at the rear of the outer cylinder body 21, and a certain gap is reserved between the hole wall of the mounting hole and the outer periphery of the bearing seat 32, and then the gap is sealed by the flexible seal 4, so that the bearing seat 32 and the outer cylinder body 21 are no longer sealed and fixedly connected by the rubber encapsulation process, but a relatively flexible connection method is used, thereby realizing a flexible connection between the inner cylinder and the outer cylinder body 21, and then the outer cylinder body 21 is connected to the first bracket 61. The bearing seat 32 is connected to the second bracket 62, so that the mounting frame 6 can support the outer cylinder body 21 and the bearing seat 32 respectively, so that the bearing seat 32 is no longer in direct contact with the outer cylinder body 21, and the vibration of the inner cylinder shaft 33 can be avoided from being directly transmitted from the bearing seat 32 to the outer cylinder body 21, causing the outer cylinder body 21 to vibrate greatly. The vibration will not only generate loud noise, but also cause other parts fixedly connected to the outer cylinder body 21 to fatigue and fail due to long-term and large vibration, or the connection with the outer cylinder body 21 to loosen and fall off.

[0060] Optionally, in an implementation of the present embodiment, there is a gap between the outer periphery of the bearing seat 32 and the mounting hole, and a flexible seal 4 is provided in the gap to achieve a flexible and sealed connection between the rear wall of the outer cylinder body 21 and the bearing seat 32 .

[0061] Optionally, in an implementation of this 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 gap, which surrounds the outer circumference of the bearing seat 32. The gap distance of the gap is the ring width of the circular gap. The bearing seat 32 will generate certain vibrations when rotating with the inner tube body 31. The maximum vibration offset is the maximum offset distance generated when the bearing seat 32 vibrates. The ring width must be greater than the maximum vibration offset generated by the vibration to avoid collision between the bearing seat 32 and the outer tube body 21.

[0063] Optionally, in an implementation of this embodiment, the clothing processing device further includes:

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

[0065] A tension spring 5, one end of which is connected to the top of the outer cylinder body 21, and the other end is connected to the box body 1;

[0066] The damper 7 has one end connected to the bottom of the mounting frame 6 and the other end connected to the base 101 .

[0067] Specifically, the number of tension springs 5 ​​can be four, and one can be set at each of the four corners of the top of the outer cylinder body 21. The top of the outer cylinder body 21 is connected to the top of the box body 1 through the tension spring 5, and the bottom of the outer cylinder body 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. The number of dampers 7 can be four, and one can be set at each of the four corners of the mounting frame 6. The inner cylinder body 31 of the inner cylinder is set inside the outer cylinder body 21, and the mounting seat extends from the mounting hole at the rear of the outer cylinder body 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 by the damper 7 to prevent the vibration from being transmitted to the ground.

[0068] Optionally, in an implementation of this embodiment, a vibration-damping and limiting component is provided between the mounting frame 6 and the outer cylinder body 21, and the vibration-damping and limiting component has a thrust along the axial direction of the outer cylinder body 21 and acts on the mounting frame 6 and the outer cylinder body 21 respectively;

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

[0070] Specifically, since both the inner cylinder and the outer cylinder body 21 are fixed on the mounting frame 6, part of the vibration generated by the bearing seat 32 of the inner cylinder will also be transmitted from the mounting frame to the outer cylinder body 21. The vibration that is about to be transmitted from the mounting frame 6 to the outer cylinder body 21 can be absorbed by the shock-absorbing and limiting component, thereby reducing the vibration transmitted from the mounting frame 6 to the outer cylinder body 21.

[0071] Moreover, the thrust increase rate of the vibration-damping and limiting mechanism is greater than the increase rate of its compression amount, so that when the vibration-damping mechanism is compressed to a certain value, the vibration-damping and limiting mechanism can play a certain limiting role when the vibration of the mounting frame 6 is large, thereby preventing the outer cylinder body 21 from vibrating greatly along with the mounting frame 6, causing the outer cylinder body 21 to collide with the inner cylinder.

[0072] Optionally, in an implementation of this embodiment, the limiting component is a bushing 8, which extends axially along the outer cylinder body 21, and the two ends of the bushing 8 along the axial direction of the outer cylinder body 21 are respectively connected to the outer cylinder body 21 and the mounting frame 6;

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

[0074] Optionally, in an implementation of this embodiment, a bracket connecting seat 9 is provided above the first bracket 61;

[0075] The bottom of the bracket connecting seat 9 is connected to the first bracket 61, and the top of the bracket connecting seat 9 has a mounting block 901 extending along the axial direction of the outer cylinder body 21. One end of the bushing 8 along the axial direction of the outer cylinder body 21 is connected to the mounting block 901, and the other end is connected to the outer cylinder body 21.

[0076] Specifically, the outer cylinder body 21 can be provided with reinforcing ribs or mounting structures at positions corresponding to the bushing 8, and fixedly connected to the bushing 8. The bushing 8 is connected via the bracket connecting seat 9, so that the bushing 8 can extend axially, that is, in the same extension direction as the outer cylinder body 21, thereby fully reducing the vibration transmitted to the outer cylinder body 21 by the mounting frame 6, and limiting the outer cylinder body 21 to avoid collision between the outer cylinder body 21 and the inner cylinder body 31.

[0077] Among them, when the relative vibration between the inner cylinder body 31 and the outer cylinder body 21 is large, the nonlinear stiffness surge stage of the bushing 8 can just play a limiting role. The design of the stiffness and deformability of the bushing 8 needs to be determined according to the minimum design spacing of the inner / outer cylinder; the thrust increases with the increase of the compression of the vibration reduction and limiting mechanism, and the increase rate of the thrust is greater than the increase rate of the compression, that is: with the increase of the compression of the bushing 8, the nonlinear stiffness surge stage of the bushing 8 is fully utilized, and then the relative displacement of the inner cylinder body 31 and the outer cylinder body 31 can be limited, thereby playing a role of limiting protection.

[0078] Moreover, rubber will produce certain plastic deformation under the action of large impact, but it still has elastic recovery ability. Since the nut is used to pre-tighten the bushing 8 during the installation stage, the deformation of the bushing 8 during pre-tightening will compensate for the plastic deformation under the action of large impact to a certain extent. Therefore, the bushing 8 will not loosen under static conditions after the impact. Large impact conditions rarely occur, and the limiting role here is just in case.

[0079] Optionally, in an implementation of this embodiment, the clothing processing device further includes:

[0080] A second bracket 62, the top of which is connected to the bearing seat 32, and the bottom of which is connected to the mounting frame 6;

[0081] The top of the second bracket 62 has an arc surface adapted to the bottom of the bearing seat 32 , and the second bracket 62 is connected to the bottom of the bearing seat 32 via the arc surface.

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

[0083] Optionally, in an implementation of the present embodiment, the flexible seal 4 is made of rubber material, and has a circular ring structure, wherein the inner ring and the outer ring are detachably sealedly connected to the mounting holes of the bearing seat 32 and the outer cylinder body 21, respectively.

[0084] Specifically, the flexible seal 4 can be made of rubber material. The flexible seal 4 can not only seal the gap, but also play a certain supporting role for the bearing seat 32, and can also reduce the vibration transmitted from the bearing seat 32 to the outer cylinder body 21 through its own elasticity.

[0085] The detachable setting of the flexible seal 4 can facilitate after-sales maintenance. When cleaning is required, the flexible seal 4 can be removed and inserted into the outer cylinder body 21 through the gap for cleaning.

[0086] Optionally, in one implementation of the present embodiment, the outer ring 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 body 21.

[0087] Specifically, the disassembly and assembly structure can be realized by sleeve-installing the installation protrusion 3201 and interference fit with the installation hole of the outer cylinder body 21. When the inner ring of the flexible seal 4 is sleeved on the circumferential installation 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 installation hole of the outer cylinder body 21, a waterproof coating is also applied, which can achieve a better sealing effect.

[0088] Optionally, in one implementation of this embodiment, the inner ring of the flexible seal 4 has an inner ring portion that cooperates with the bearing seat 32, and an outer ring portion that cooperates with the mounting hole of the outer cylinder body 21;

[0089] Among them, the inner ring part and the outer ring part are hardened.

[0090] Specifically, the inner ring component of the flexible seal 4 can be a part with the inner wall of the inner ring as the starting point and a ring thickness of 2mm to 5mm, and the outer ring component of the flexible seal 4 can be a part with the outer wall of the outer ring as the starting point and a ring thickness of 2mm to 5mm. Through hardening treatment, the flexible seal 4 can be better assembled with the outer periphery of the bearing seat 32 and the mounting hole of the outer cylinder body 21, and sealed.

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

[0092] The middle part between the inner circle part and the outer circle part;

[0093] The middle portion has a plurality of annular folds.

[0094] Specifically, except for the hardened part mentioned above, the rest of the parts can be designed with wrinkles. The wrinkles 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 wrinkles can make the flexible seal 4 have better vibration absorption performance, and can further reduce the vibration of the bearing seat 32 transmitted from the flexible seal 4 to the outer cylinder body 21.

[0095] Specific assembly process:

[0096] The outer cylinder body 21 can be connected to the mounting frame 6 by bolts.
