Description

Technical Field

[0001] This utility model belongs to the field of clothing processing equipment, specifically, it relates to a vibration damping component and clothing processing equipment. Background Technology

[0002] During the spin-drying start-up and operation phases of a washing machine, due to uneven distribution of laundry leading to unbalanced load and the strong centrifugal force generated during the spin-drying process, the washing machine's spin-drying drum will inevitably shake and resonate.

[0003] To address this issue, washing machines are designed with specialized vibration damping components, typically installed between the washing machine's casing and outer tub. Currently, these components use a combination of damping and springs to reduce vibration in the outer tub. During the initial spin-drying phase, the outer tub vibrates significantly, and the damping system effectively reduces this vibration, preventing the outer tub from impacting the casing. However, during high-speed spin-drying, the outer tub vibrates less. At this stage, the damping structure wears down due to continuous operation, leading to faster component failure and increased noise due to resonance between the outer tub and casing. Existing vibration damping components cannot meet the damping force requirements of pulsator washing machines under various operating conditions.

[0004] To further address the aforementioned issues, a variable damping vibration reduction assembly can be implemented. The damping structure of this assembly is housed within a damping cavity, with a certain distance between one axial end of the damping structure and one end of the damping cavity. When the vibration amplitude of the outer tub is small, the damping cavity does not press against the damping structure, and no damping force is generated. When the vibration exceeds the specified distance, the damping cavity will press against the damping structure, causing deformation and generating damping force. However, during the washing machine's operation, water may splash out of the washing tub, causing moisture inside the damping cavity. If the air inside remains damp for an extended period, it can lead to damage to the damping cavity, suspension rods, or damping structure, or even the generation of unpleasant odors.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art. The first objective is to provide a vibration damping component for a garment processing device. By providing a vent hole in the damping cavity of the variable damping vibration damping component, the damping cavity can discharge moisture outward through the vent hole, thereby preventing dampness inside the damping cavity and thus preventing damage to the vibration damping component or the generation of odors.

[0007] The second objective of this invention is to provide a garment processing device.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: The first aspect provides a vibration damping component for a garment processing device, including: a hanging rod;

[0009] A damping cavity through which the boom is axially movable;

[0010] A damping structure is fitted onto a hanger inside the damping cavity; there is a certain distance between one axial end of the damping cavity and the damping structure, so that when the vibration exceeds a preset amplitude, the damping cavity presses against the damping structure to generate a damping force;

[0011] The damping cavity is provided with vent holes for moisture removal.

[0012] Furthermore, the vibration damping component includes an upper support and a lower support, which are connected to each other to form a damping cavity; the vent hole is disposed through the lower support.

[0013] Furthermore, the upper support and the lower support are connected relative to each other to form the damping cavity, or the bottom of the upper support extends into the lower support to form the damping cavity;

[0014] The ventilation holes are located at the bottom of the peripheral wall of the lower support or on the bottom wall of the lower support.

[0015] Furthermore, the vibration damping component includes a rod seat, a base, and a spring. The rod seat is located at one end of the rod, and the other end of the rod passes through the damping cavity and the spring in sequence before being connected to the base.

[0016] The vibration damping component also includes a noise reduction structure, which is sleeved on the hanger base and / or sleeved on the outer periphery of one end of the upper support base near the hanger base.

[0017] Furthermore, the outer periphery of the boom seat is provided with an annular protrusion, and the noise reduction structure is an annular felt, which is sleeved on the annular protrusion.

[0018] Furthermore, the spring is a variable pitch spring, wherein the pitch at both ends of the spring is smaller than the pitch in the middle portion.

[0019] Furthermore, the damping structure includes a damping deformation section and a mounting bracket sleeved on the outer periphery of the damping deformation section;

[0020] The damping cavity has protruding pressing parts on both ends of its axial direction, which are opposite to the damping deformation part. These parts are used to generate damping force by pressing against the damping deformation part after the movement exceeds a preset range, so that the mounting bracket is spaced apart from the axial end face of the damping cavity.

[0021] Furthermore, the pressing part includes a pressing column, and the two axial ends of the mounting frame protrude from the two axial ends of the damping deformation part. When the vibration is less than the preset amplitude, at least one end of the pressing column extends into the mounting frame and is spaced apart from the damping deformation part.

[0022] Furthermore, a plurality of buffer blocks are spaced circumferentially on the bottom wall of the damping cavity, and are arranged opposite to the mounting bracket.

[0023] The vent is located on the bottom wall of the damping cavity between two adjacent buffer blocks.

[0024] The second aspect of this utility model provides a garment processing device, including a box, a drum module, and any of the above-described vibration damping components, wherein the two ends of the vibration damping component are respectively installed on the box and the drum module.

[0025] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0026] This invention provides a vent hole in the damping cavity of the variable damping vibration damping component, allowing moisture to escape from the damping cavity and preventing dampness inside, thus avoiding damage to the vibration damping component or the generation of odors.

[0027] When the vent is located at the bottom of the damping cavity, it can also drain water that splashes into the damping cavity.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] like Figures 1 to 12 As shown, this utility model provides a vibration damping component for a clothing processing device. The vibration damping component is installed on the clothing processing device (such as a washing machine) to absorb, disperse, or convert the vibration energy generated by the device during operation, so as to reduce vibration and noise transmission, ensure the smooth operation of the device, protect its structure, and reduce the noise generated during operation.

[0048] The vibration damping component can be applied between the washing machine's cabinet and drum modules to reduce vibration.

[0049] The vibration damping component includes a suspension rod 2, a damping cavity 1, and a damping structure 3.

[0050] The suspension rod 2 is axially movable through the damping cavity 1.

[0051] The damping structure 3 is fitted onto the suspension rod 2 within the damping cavity 1. When subjected to vibration, the suspension rod 2 moves relative to the damping cavity 1. A certain distance exists between one axial end of the damping cavity 1 and the damping structure 3, meaning the axial extension length of the damping cavity 1 is greater than the axial extension length of the damping structure 3. When the vibration exceeds a preset amplitude, the damping cavity 1 deforms against the damping structure 3, moving along the suspension rod 2 through friction to generate damping force. In other words, no damping force is generated when the vibration is below the preset amplitude, but it begins to generate damping force after the vibration exceeds the preset amplitude.

[0052] The damping cavity 1 is provided with a vent 15 for dehumidification.

[0053] This invention provides a vent 15 in the damping cavity 1 of the variable damping vibration damping component. The damping cavity 1 can expel moisture through the vent 15, which can prevent the damping cavity 1 from becoming damp, thereby preventing damage to the vibration damping component or the generation of odor.

[0054] The vent 15 can be provided on the bottom wall and / or peripheral wall of the damping cavity 1.

[0055] One approach is that the damping structure 3 can abut against the inner peripheral wall of the damping cavity 1, generating frictional damping force when it moves under the pressure of the damping cavity 1. When the vibration is below a preset amplitude, the movement of the damping cavity 1 generates frictional force between itself and the outer peripheral wall of the damping structure 3 to reduce vibration; when the vibration exceeds the preset amplitude, the damping structure 3 begins to generate damping force by moving along the suspension rod 2 under the pressure of the damping cavity 1, further improving the vibration reduction effect.

[0056] Another option is that the damping structure 3 can also move freely relative to the damping cavity 1. There is a gap between the outer peripheral wall of the damping structure 3 and the inner peripheral wall of the damping cavity 1. After the vibration exceeds a preset amplitude, the damping structure 3 is fixed to the suspension rod 2 and, under the pressure of the damping cavity 1, begins to generate damping force through frictional movement along the suspension rod 2. That is, no damping force is generated when the vibration is below the preset amplitude, and damping force begins to be generated after the vibration exceeds the preset amplitude. This avoids continuous wear on the damping structure 3, increasing its service life and effectiveness.

[0057] The variable damping vibration reduction component of this invention, when generating small-amplitude vibrations such as during high-speed dehydration, has its damping cavity 1 moving downwards without pressing against the damping structure 3, preventing it from rubbing against the hanging rod 2 and generating no damping force. In this case, vibration reduction can be achieved solely using the spring 4, avoiding excessive shaking of the entire machine during dehydration. When large-amplitude vibrations occur at the start of dehydration, the damping cavity 1 moves downwards beyond a preset amplitude, pressing against the damping structure 3 and causing it to rub against the hanging rod 2, generating damping force. The damping structure 3, in conjunction with the spring 4, then performs vibration reduction. This invention avoids the generation of damping force and wear on the damping structure 3 throughout the entire vibration process, reduces vibration noise, and improves the applicability of clothing processing equipment under various operating conditions.

[0058] The preset amplitude is greater than or equal to the axial length difference ΔL between the damping cavity 1 and the damping structure 3.

[0059] The vibration damping component includes an upper support base 11 and a lower support base 12.

[0060] The upper support 11 and lower support 12 of the vibration damping component are press-fitted together to form the deformation cavity 13 and the damping cavity 1. The pressing part 112 is provided to protrude inward along the shaft hole at one end of the damping cavity 1, and its extension direction is axial.

[0061] The ventilation hole 15 is provided through the lower support base 12.

[0062] In a preferred embodiment, the vent 15 is located at the bottom of the lower support 12, so that when water enters the damping cavity 1, the water can be discharged through the vent 15.

[0063] like Figures 1 to 6 As shown, one structural design for the damping cavity 1 is that the bottom of the upper support 11 extends into the lower support 12 to form the damping cavity 1. The vent hole 15 is disposed through the lower support 12.

[0064] Specifically, the bottom of the upper support 11 is provided with a downwardly protruding annular wall 111, which extends into the cavity of the lower support 12 to form the damping cavity 1. In the initial state, the end of the annular wall 111 is a certain distance from the bottom wall of the cavity of the lower support 12. The extension length of the annular wall 111 is less than the extension length of the inner cavity of the lower support 12.

[0065] A deformation cavity 13 is formed between the bottom wall of the annular wall 111 of the upper support 11 and the outer periphery of the cavity opening of the lower support 12. The damping structure 3 is installed in the cavity within the annular wall 111. In the initial state, there is a certain distance between the lower end of the damping structure 3 and the upper end of the pressing part 112.

[0066] The vibration damping component also includes a noise reduction unit 14, which is respectively disposed between the two axial ends of the damping cavity 1 and the damping deformation part 32 of the damping structure 3.

[0067] A noise reduction unit 14 is provided between one axial end of the damping cavity 1 and the damping structure 3, effectively buffering the collision between the two during vibration and preventing the collision energy from being converted into sound wave propagation, thereby significantly reducing noise generation. The noise reduction unit 14 not only reduces the direct impact between the damping cavity 1 and the damping structure 3, reducing component wear caused by long-term vibration and extending the service life of the vibration damping components, but also improves the user experience.

[0068] Even if a slight collision sound may occur between the damping cavity 1 and the damping structure 3, it can be masked by the background noise during normal machine operation, thus not causing auditory interference to the user.

[0069] The noise reduction unit 14 includes a pressure plate 141. One end of the pressure plate 141 is connected to one end face of the pressure part 112, and the other end extends a certain length along the axial direction.

[0070] like Figures 7 to 12 As shown, another structural design for the damping cavity 1 is that the upper support 11 and the lower support 12 are connected by mutual pressing to form the damping cavity 1. The vent hole 15 is disposed through the lower support 12.

[0071] Specifically, the bottom of the upper support 11 presses against the outer periphery of the recessed opening of the lower support 12, blocking the recessed opening, and the two together form the damping cavity 1.

[0072] Preferably, the upper support 11 is a spherical seat. The cover of the spherical seat is fastened to the outer periphery of the top of the lower support 12, and cooperates with the outer periphery of the top opening of the lower support 12 to form a deformation cavity 13. When the spherical seat is compressed by an external force against the lower support 12, the cover will flatten.

[0073] Of course, other damping cavity structures can also be applied to this invention.

[0074] In all the above solutions, the vent hole 15 can be located at the bottom of the peripheral wall of the lower support 12 or on the bottom wall of the lower support 12, allowing for ventilation and moisture discharge, as well as drainage.

[0075] The vibration damping component includes a rod seat 6, a base 5, and a spring 4. The rod seat 6 is located at one end of the rod 2, and the other end of the rod 2 is connected to the base 5 after passing through the damping cavity 1 and the spring 4 in sequence.

[0076] One end (the upper end) of the suspension rod 2 is fixed to the washing machine's casing, and the lower end of the suspension rod 2 is fixed to the base 5 of the vibration damping component. The spring 4 of the vibration damping component is sandwiched between the lower end of the damping cavity 1 and the base 5. The tub load module is loaded at the upper end of the damping cavity 1.

[0077] The vibration damping component also includes a noise reduction structure 7. The noise reduction structure 7 is sleeved on the hanger base 6, and / or sleeved on the outer periphery of the upper support 11 near one end of the hanger base 6, for reducing the noise generated during the use of the vibration damping component.

[0078] The noise reduction unit 14 includes an annular felt, a flower-shaped felt or other shapes formed by circumferentially protruding or recessing from the outer periphery of the annular felt.

[0079] The outer periphery of the boom seat 6 is provided with an annular protrusion 8, and the noise reduction structure 7 is an annular felt, which is sleeved on the annular protrusion 8. By setting the annular protrusion 8, the annular felt can be fixed and prevented from falling off.

[0080] Furthermore, the spring 4 is a variable pitch spring, where the pitch at both ends of the spring is smaller than the pitch in the middle. Alternatively, the pitch at both ends of the spring is larger than the pitch in the middle.

[0081] This invention utilizes a variable pitch spring, which exhibits high fatigue resistance. The stiffness and compression degree of the variable pitch spring can be adjusted by modifying the working length and pitch, allowing for convenient adjustment of elastic characteristics to meet the needs of different working conditions. Furthermore, the non-uniform helical structure of the variable pitch spring enables it to adapt to various stress environments, such as nonlinear loading environments or complex environments with non-uniform forces.

[0082] When the vibration exceeds the preset amplitude, the small-pitch part of the spring is compressed, and at this time the spring characteristics will change abruptly, generating greater elastic force, which can better reduce vibration by combining with the variable resistance characteristics.

[0083] The damping structure 3 includes a damping deformation part 32 and a mounting bracket 31. The mounting bracket 31 is sleeved on the outer periphery of the damping deformation part 32 and is used to confine the damping deformation part 32 inside it.

[0084] The mounting bracket 31 includes a mounting sleeve 311, and the damping deformation part 32 is located inside the mounting sleeve 311. The mounting sleeve 311 has two axial openings 312 with inwardly protruding snap-fit ​​members 313. The snap-fit ​​members 313 abut against the axial end faces of the damping deformation part 32 to prevent the damping deformation part 32 from dislodging from the mounting sleeve 311.

[0085] The snap-fit ​​member 313 abuts against the axial end face of the damping deformation part 32.

[0086] Preferably, the mounting sleeve 311 is cylindrical, and the shape of the damping cavity 1 that moves in conjunction with the mounting sleeve 311 matches each other.

[0087] Preferably, one end of the snap-fit ​​member 313 is connected to the inner peripheral wall of the opening 312 at one end of the mounting bracket 31, and the other end extends circumferentially and protrudes from the inner peripheral wall of the mounting bracket 31. That is, there is a gap between the other end of the snap-fit ​​member 313 and the inner peripheral wall of the mounting bracket 31. The inner peripheral wall of the mounting bracket 31 is provided with a relief groove 314, which is opposite to the other end of the snap-fit ​​member 313, and the elastic snap-fit ​​member 313 can move outward into the relief groove 314 under force.

[0088] like Figures 7 to 12As shown, the damping cavity 1 has protruding pressing portions 112 on both ends of its axial direction, which are opposite to the ends of the damping deformation portion 32. During the process of the pressing portion 112 moving beyond a preset range and pressing against the damping deformation portion 32 to generate damping force, the mounting bracket 31 is spaced apart from the axial end face of the damping cavity 1, and the pressing portion 112 serves to reduce noise.

[0089] The distance between the two pressing parts 112 is greater than the axial length of the damping deformation part 32, and the difference between the two is ΔL.

[0090] The damping deformation section 32 is confined within the mounting bracket 31. When the vibration exceeds a preset amplitude, the pressing section 112 will first press against a portion of the damping deformation section 32 to deform, preventing the end face of the damping cavity 1 from directly impacting the mounting bracket 31 and producing a clicking sound.

[0091] When the pressing part 112 presses against the damping deformation part 32 to deform, the mounting bracket 31 restricts the deformation of the damping deformation part 32 to the outer periphery and cooperates to squeeze the damping deformation part 32 to deform inward, thereby enhancing the adhesion between the damping deformation and the rod 2.

[0092] The pressing part 112 protrudes from the outer periphery of the shaft holes at both ends of the damping cavity 1. It can be arranged circumferentially or at intervals. The pressing part 112 and the damping cavity 1 are an integral structure.

[0093] The pressure-reducing part 112 includes a pressure-reducing column 1121. The axial ends of the mounting bracket 31 protrude from the axial ends of the damping deformation part 32. When the vibration is less than a preset amplitude, at least one end of the pressure-reducing column 1121 extends into the mounting bracket 31, spaced apart from the damping deformation part 32. By setting the pressure-reducing part 112 as a pressure-reducing column 1121, the pressure-reducing and noise-reduction effects are improved.

[0094] The pressing part 112 of this utility model extends inward along the shaft hole of the upper support 11 for a certain length, allowing the suspension rod 2 to pass through. This prevents the damping cavity 1 and the suspension rod 2 from tilting during use, thus avoiding friction, interference, and abnormal noise. It can also extend into the mounting bracket 31 when the vibration is less than the preset amplitude.

[0095] Multiple buffer blocks 121 are spaced circumferentially on the bottom wall of the damping cavity 1, and the multiple buffer blocks 121 are arranged opposite to the mounting frame 31. The vent holes 15 are arranged on the bottom wall of the damping cavity 1 between two adjacent buffer blocks 121 to prevent the mounting frame 31 from affecting the ventilation and drainage functions of the vent holes 15.

[0096] The second aspect of this utility model provides a garment processing device, including a box, a drum module, and any of the above-described vibration damping components, wherein the two ends of the vibration damping component are respectively installed on the box and the drum module.

[0097] Preferably, the garment processing device is a pulsator washing machine, and the tub module includes an outer tub.

[0098] The upper end of the suspension rod 2 is fixed to the washing machine's casing, and the lower end of the suspension rod 2 is fixed to the base 5 of the vibration damping component. The spring 4 of the vibration damping component is sandwiched between the lower end of the damping cavity 1 and the base 5. The washing tub is loaded on the upper end of the damping cavity 1. The vibration damping component can also be connected to the casing and the outer tub using other structures.

[0099] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
