Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically, it relates to a shock absorber for clothing processing equipment, clothing processing equipment and its control method. Background Technology

[0002] In this invention, "clothing processing equipment" refers to a general term for a class of household appliances that can perform washing, dehydration, drying and other processes, such as washing machines and washer-dryer combos.

[0003] Taking washing machines as an example, because washing machines generate strong vibrations during operation, vibration dampers are usually installed between the washing machine's casing and outer drum. The magnitude of vibration varies at different operating stages; the vibration is greater at low speeds and less at high speeds. Therefore, the vibration damper needs to provide greater damping force when the washing machine experiences greater vibration at low speeds and less damping force when it experiences less vibration at high speeds. However, existing friction vibration dampers provide the same damping force regardless of whether the washing machine is operating at low or high speeds, which cannot meet the damping force requirements of washing machines at both low and high speeds, and may even cause significant noise, affecting the user experience.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention 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 the present invention, but are not intended to limit the scope of the present invention.

[0057] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 limiting this invention.

[0058] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 invention based on the specific circumstances.

[0059] like Figures 1-2 As shown, the present invention provides a vibration damper for a garment processing device, the vibration damper comprising a vibration damper cylinder 1, a vibration damper rod 2, a damping force providing unit 3, and a damping force adjusting unit 4.

[0060] Specifically, one end of the damper rod 2 is located inside the damper cylinder 1, allowing it to reciprocate within the cylinder. The damping force providing unit 3 is sleeved on the outer periphery of the damper rod 2, providing damping force through axial sliding relative to the rod 2. The damping force adjusting unit 4 is installed outside the damper cylinder 1 and connected to the damping force providing unit 3, used to adjust the magnitude of the damping force provided by the unit 3. It can be understood that the damper rod 2 is coaxially aligned with the damper cylinder 1 and can reciprocate along the axial direction within the cylinder 1.

[0061] The vibration damper of the present invention can adjust the damping force to meet the different damping force requirements of the garment processing equipment at different operating stages, prevent the garment processing equipment from generating huge noise during operation, extend the service life of the garment processing equipment, and improve the user experience.

[0062] Preferably, the damping force adjustment unit 4 adjusts the magnitude of the damping force by adjusting the pressure between the damping force providing unit 3 and the damper rod 2. When the pressure between the damping force adjustment unit 4 and the damper rod 2 increases, the damping force provided by the damper rod 2 when it slides axially relative to the damping force adjustment unit 4 increases. Conversely, when the pressure between the damping force adjustment unit 4 and the damper rod 2 decreases, the damping force provided by the damper rod 2 when it slides axially relative to the damping force adjustment unit 4 decreases.

[0063] Preferably, the damping force providing unit 3 and the damping force adjusting unit 4 cooperate to form a clamp structure sleeved on the outer periphery of the shock absorber rod 2. The clamp structure simplifies the overall complexity of the shock absorber and makes installation and disassembly more convenient.

[0064] Preferably, the damping force providing unit 3 is connected to the damper cylinder 1, and the damper rod 2 can slide together with the damping force providing unit 3 along the axial direction of the damper rod 2, providing damping force during the sliding process.

[0065] Furthermore, such as Figures 3-4 As shown, the damping force providing unit 3 includes a clamping unit 31, which is sleeved on the outer periphery of the damper rod 2 and slides together with the damper cylinder 1 along the axial direction of the damper rod 2 to provide damping force. Specifically, the clamping unit 31 is mounted on the damper cylinder 1, and the arc surface of the clamping unit 31 facing the outer periphery of the damper rod 2 is designed as a friction surface, thereby generating damping force when the clamping unit 31 and the damper cylinder 1 slide together along the axial direction of the damper rod 2. Preferably, the clamping unit 31 is mounted at the open end of the damper cylinder 1. It can be understood that by providing a first concave-convex part on the clamping unit 31 and a second concave-convex part at the open end of the damper cylinder 1, the two are engaged through the convex-convex cooperation of the first and second concave-convex parts.

[0066] As an alternative to designing the arcuate surface of the clamping unit 31 facing the outer periphery of the damper rod 2 as a friction surface, the damping force providing unit 3 includes a friction unit 32. The friction unit 32 is mounted on the arcuate surface of the clamping unit 31 facing the outer periphery of the damper rod 2, located between the clamping unit 31 and the damper rod 2, and in contact with the outer periphery of the damper rod 2. It is understood that the friction unit 32 includes, but is not limited to, friction plates or friction strips, the size and shape of which are adapted to the arcuate surface.

[0067] As an alternative to mounting the clamping unit 31 on the damper cylinder 1, the damping force providing unit 3 further includes a fixing unit 33. The clamping unit 31 is mounted on the fixing unit 33, which is connected to the damper cylinder 1, allowing the clamping unit 31 and the damper cylinder 1 to slide together along the axial direction of the damper rod 2, thereby generating a damping force. Preferably, the fixing unit 33 and the damper cylinder 1 are an integral structure.

[0068] Furthermore, the fixing unit 33 is sleeved on the outer periphery of the shock absorber rod 2. A mounting portion penetrating the periphery of the fixing unit 33 is provided on its peripheral wall, connecting the interior and exterior of the shock absorber cylinder 1. The mounting portion extends circumferentially along a portion of the outer periphery of the shock absorber cylinder 1, forming a roughly arc-shaped profile. The clamping unit 31 is mounted on the mounting portion, thereby achieving assembly of the two. It can be understood that the mounting portion is a through hole penetrating the periphery of the fixing unit 33.

[0069] The number of mounting parts is at least one, preferably two, and the two mounting parts are symmetrically arranged about the damper cylinder 1. In addition, the mounting parts are arranged near the open end of the damper cylinder 1. The purpose is that when the damper rod 2 is located inside the damper cylinder 1, the distance from the open end of the damper cylinder 1 to the end of the damper rod 2 near the bottom of the damper cylinder 1 is greater than the distance from the open end of the damper cylinder 1 to the end of the damper rod 2 away from the bottom of the damper cylinder 1. This ensures that when the damper rod 2 and the damping force providing unit 3 are in contact and move relative to each other, the duration of the damping force generated is longer, thereby further improving the vibration reduction effect.

[0070] Furthermore, the mounting part has a positioning groove 331 extending along the thickness direction of the peripheral wall of the fixing unit 33. The clamping unit 31 is provided with a positioning protrusion 311 that mates with the positioning groove 331. The positioning protrusion 311 extends along the axial direction of the shock absorber cylinder 1. During installation, the positioning protrusion 311 is snapped into the positioning groove 331 to achieve assembly. The interlocking fit between the positioning groove 331 and the positioning protrusion 311 ensures that the clamping unit 31 can be detachably mounted on the peripheral wall of the shock absorber cylinder 1, improving the efficiency of installation and removal of the clamping unit 31 and the shock absorber cylinder 1, and facilitating replacement of the clamping unit 31 by personnel. It is understood that the number of positioning grooves 331 and positioning protrusions 311 is the same, and there are multiple of each. The positioning protrusions 311 are divided into two groups, preferably four in each group, and are correspondingly installed in the positioning grooves 331.

[0071] In addition, the positioning groove 331 extends vertically along the thickness direction of the peripheral wall of the fixed unit 33. The advantage of this design is that when installing the clamping unit 31, since the positioning groove 331 extends vertically along the thickness direction of the peripheral wall of the fixed unit 33, the force applied by the operator is often in the same direction as the vertical extension of the positioning groove 331. When the force applied by the operator is constant, it ensures that the force can be used entirely for installing the clamping unit 31, which is relatively labor-saving. In contrast, if the positioning groove 331 extends obliquely along the thickness direction of the peripheral wall of the fixed unit 33, since there is an angle between the force applied by the user and the direction of movement of the clamping unit 31, only a portion of the force applied by the user is used to push the clamping unit 31 to move, further reducing the assembly efficiency. In order to improve the assembly efficiency, the operator has to apply a larger force, which is seriously laborious.

[0072] Preferably, the clamping unit 31 is provided with a connecting part 312 protruding from the outer periphery of the fixing unit 33, and the damping force adjustment unit 4 is mounted on the connecting part 312;

[0073] Specifically, the clamping unit 31 is in the shape of an arc-shaped sheet, and the connecting portion 312 extends outward from both ends of the clamping unit 31 along its length. Preferably, the clamping unit 31 is semi-circular.

[0074] Furthermore, there are two clamping units 31, which are symmetrically arranged about the damper rod 2, and the two adjacent connecting parts 312 of the two clamping units 31 are arranged opposite each other.

[0075] Furthermore, a through mounting hole is provided on the connecting part 312.

[0076] Preferably, the damping force adjustment unit 4 includes a drive unit 41 and a transmission unit 42. The transmission unit 42 is connected to two adjacent connecting parts 312 through mounting holes. Driven by the drive unit 41, the transmission unit 42 moves the two adjacent connecting parts 312 of the clamping unit 31 closer or further away. When the two connecting parts 312 move towards each other and closer, the pressure between the clamping unit 31 and / or the friction unit 32 and the damper rod 2 increases, and the damping force provided by the clamping unit 31 and / or the friction unit 32 relative to the damper rod 2 through axial sliding increases accordingly. Conversely, when the two connecting parts 312 move away from each other, the pressure between the clamping unit 31 and / or the friction unit 32 and the damper rod 2 decreases, and the damping force provided by the clamping unit 31 and / or the friction unit 32 relative to the damper rod 2 through axial sliding decreases accordingly. It is understood that the drive unit 41 includes, but is not limited to, a drive motor, and the transmission unit 42 includes, but is not limited to, a rack, a gear, and a screw. The gear is fixedly installed but can rotate under the transmission action of the drive motor and the rack. The outer circumference of the gear is provided with teeth that mesh with the rack, and the inner circumference of the gear is provided with threads. Half of the threads on the outer circumference of the screw are clockwise, and the other half are counterclockwise. The gear is fitted into the middle of the threads and fits tightly with the threads. During operation, the drive motor drives the rack transmission, causing the gear to rotate relative to the rack in a fixed position. Due to the rotation of the gear in place, the screw connected to the gear is driven to rotate. As the screw rotates, the two adjacent connecting parts 312 connected to the screw move towards each other, changing the pressure between the clamping unit 31 and / or the friction unit 32 and the damper rod 2. When the clamping unit 31 slides axially relative to the damper rod 2, the damping force is changed.

[0077] The present invention also provides a garment processing device, including a housing, an outer drum, and an inner drum. The housing constitutes the exterior of the garment processing device, the outer drum is suspended and supported inside the housing for holding washing water, and the inner drum is rotatably disposed inside the outer drum for performing washing and spin-drying.

[0078] Furthermore, a vibration damper is installed between the outer cylinder and the housing. One end of the vibration damper is fixedly connected to the housing, and the other end is fixedly connected to the outer cylinder. This is used to reduce noise caused by vibration during the operation of the garment processing equipment. It is understood that the other end of the vibration damper is connected to the outer cylinder near the bottom. The vibration damper of this invention provides a large damping force when the garment processing equipment is operating at low and medium speeds with large vibration amplitudes. When the garment processing equipment is operating at high speeds, the vibration amplitude is minimal, and the vibration damper provides a small damping force. When the vibration of the garment processing equipment is very small, the damping force would hinder its normal operation, and the vibration damper would not provide any damping force, thereby suppressing vibration and reducing noise.

[0079] like Figure 8 As shown, the present invention also provides a control method, including,

[0080] Obtain the operating parameters of the garment processing equipment;

[0081] Damping force is obtained based on operating parameters;

[0082] Compare the damping force with the target damping force, and adjust the magnitude of the damper damping force based on the comparison results.

[0083] The control method of the present invention determines that when the damping force is less than the target damping force, the drive unit 41 controls the transmission unit 42 to move the two clamping units 31 toward the direction closer to the shock absorber rod 2, so as to increase the damping force provided by the axial sliding of the clamping units 31 relative to the shock absorber rod 2; or, when the damping force is greater than the target damping force, the drive unit 41 controls the transmission unit 42 to move the two clamping units 31 away from the shock absorber rod 2, so as to reduce the damping force provided by the axial sliding of the clamping units 31 relative to the shock absorber rod 2, thereby balancing the vibrations of different degrees generated during the operation of the clothing processing equipment.

[0084] Preferably, obtaining the target damping force includes,

[0085] Detect the eccentricity of the inner cylinder;

[0086] Determine whether the eccentricity of the inner drum is less than or equal to the preset eccentricity. If not, redistribute the clothes in the inner drum until the eccentricity of the inner drum detected after redistribution is less than or equal to the preset eccentricity. If yes, determine the target damping force based on the eccentricity of the inner drum.

[0087] Preferably, the target damping force is determined based on the eccentricity of the inner cylinder, including:

[0088] The displacement of the clamping unit 31 is obtained based on the eccentricity of the inner cylinder;

[0089] The target damping force is determined based on the displacement of the clamping unit 31;

[0090] likeFigure 5 and Figure 7 As shown, the eccentricity of the inner cylinder and the displacement of the clamping unit 31, as well as the displacement of the clamping unit 31 and the target damping force, are all mapping relationships. By detecting the eccentricity of the inner cylinder, the corresponding target damping force can be obtained based on the relationship between the eccentricity of the inner cylinder and the displacement, as well as the relationship between the displacement and the damping force.

[0091] The methods for obtaining the operating parameters of the garment processing equipment include capturing the vibration signals generated by the garment processing equipment during operation through vibration sensors, further analyzing the vibration signals to obtain the eccentricity of the inner drum; while the preset eccentricity refers to the maximum eccentricity value that the garment processing equipment can withstand, that is, the safe limit of eccentricity during the operation of the garment processing equipment.

[0092] Preferably, the damping force is obtained based on operating parameters, including:

[0093] The displacement of the clamping unit 31 is obtained based on the operating parameters, and the damping force is determined based on the displacement of the clamping unit 31. Specifically, such as... Figures 6-7 As shown, the operating parameters and the displacement of the clamping unit 31, as well as the displacement of the clamping unit 31 and the damping force, are all mapped. By monitoring the operating parameters of the clothing processing equipment, the corresponding damping force can be obtained based on the relationship between the operating parameters and the displacement, as well as the relationship between the displacement and the damping force.

[0094] Furthermore, the operating parameters of the garment processing equipment include, but are not limited to, the rotational speed of the inner drum and the frequency of its rotation. This invention will be illustrated using the rotational speed of the inner drum as an example.

[0095] The rotational speed of the inner cylinder is monitored to determine if it is less than or equal to a preset speed. If so, it indicates that the damping force corresponding to the current rotational speed of the inner cylinder is equal to the target damping force, and no adjustment of the damper's damping force is needed. If not, the rotational speed of the inner cylinder is reduced until it is less than or equal to the preset speed. It should be noted that the displacement of the clamping unit 31 corresponding to the preset speed is equal to the displacement of the clamping unit 31 obtained based on the eccentricity of the inner cylinder, thereby ensuring that the damping force of the damper is equal to the target damping force.

[0096] Additionally, it should be noted that, Figures 5-7 The images were all obtained by staff through numerous experiments.

[0097] In addition, such as Figure 6 , Figure 7As shown, the present invention divides the entire operation of the garment processing equipment into four preset speed ranges. The displacement of the clamping unit 31 is different for different speed ranges, which in turn leads to different damping forces for different displacements. By monitoring the rotation speed of the inner drum, it is determined which speed range the inner drum is in, thereby controlling the vibration damper to provide the damping force corresponding to that speed range. This can more effectively reduce the vibration during the operation of the garment processing equipment and further improve the stability of the garment processing equipment.
