[0057] In the prior art, drum washing machines typically use a vibration reduction system consisting of springs, shock absorbers, and counterweights (also known as balance weights) to reduce vibration. This increases the overall weight of the machine, thereby reducing the vibration generated during operation. However, the weight of existing counterweights is relatively fixed and cannot be adjusted, resulting in poor vibration reduction.
[0058] Some solutions reduce vibration by increasing the weight of the counterweight. However, this strategy is not applicable in all working conditions. The effect of increasing the weight of the counterweight is speed-dependent, such as Figure 2 The vibration amplitude-speed curve shown in the figure reveals the law of change with weight (where m1>m2>m3>m4). In the low-speed range below the resonance speed, increasing the weight of the counterweight block not only fails to reduce vibration, but may increase the vibration amplitude.
[0059] The present invention provides a laundry processing device and its control method, control device and storage medium to solve the problem of poor vibration reduction effect of existing laundry processing devices. Figures 1-7 Provide explanation.
[0060] The control method of the clothes processing device provided in the embodiment of the present application can be applied to clothes processing devices such as drum washing machines, clothes processing devices and washing and drying sets. The drum component of the clothes processing device includes an outer drum and a washing drum located inside the outer drum. The outer drum is provided with a counterweight block and an adjustment device. The adjustment device is used to adjust the weight of the counterweight block. For example, please refer to Figure 1 , Figure 1 A flow chart of a control method for a clothing processing device provided in an embodiment of the present application.
[0061] refer to Figure 1 As shown, the control method of the clothes processing device may include:
[0062] S101: In response to a preset program, controlling the clothes processing device to enter a dehydration process;
[0063] For example, the control unit of the clothing processing device monitors the current washing program. When the program reaches the dehydration stage, or the user manually selects the dehydration function, the control unit will issue an instruction to start the dehydration process: the drive motor starts to rotate the washing drum at high speed, and at the same time ensures that the drain valve is fully opened to drain the washing liquid or sewage.
[0064] S102: Obtaining the dehydration stage of the clothes processing device and the rotation speed information of the washing drum;
[0065] Specifically, the dehydration stage can be subdivided into the eccentricity detection stage, the weighing stage, the pre-dehydration stage and the main dehydration stage. The eccentricity detection stage is used to measure the uneven distribution of clothes in the washing drum. The weighing stage is used to obtain the total weight of the clothes in the washing drum. During the pre-dehydration stage, the washing drum rotates at a low or medium speed to initially remove some water and prepare for the subsequent main dehydration. The main dehydration stage is used to remove water from the clothes to the greatest extent possible.
[0066] The control unit uses a Hall effect sensor, encoder, or other speed-measuring device connected to the motor or drum shaft to accurately measure the drum's real-time speed. This information is crucial for understanding the equipment's current operating status, especially since vibration characteristics vary significantly at different speeds.
[0067] S103: Based on the dehydration stage and / or the rotation speed information, the regulating device is controlled to adjust the weight of the counterweight.
[0068] The control unit determines how to adjust the weight of the counterweight according to the current dehydration stage and speed information obtained in S102 and the preset control algorithm, thereby ensuring that the clothing processing equipment can achieve better vibration reduction effect at different dehydration stages and speeds.
[0069] In an optional embodiment, based on the dehydration stage and / or speed information, the control and adjustment device adjusts the weight of the counterweight block, including: determining the resonant speed of the drum component; when the speed information is lower than the resonant speed, the control and adjustment device reduces the weight of the counterweight block; when the speed information is greater than or equal to the resonant speed, the control and adjustment device increases the weight of the counterweight block.
[0070] Figure 2 It is the changing trend of the vibration body amplitude-speed curve with the weight of the vibration body. It can be seen that in the low-speed stage before the resonance speed, the heavier the counterweight block, the greater the vibration. Therefore, the vibration reduction system of the drum washing machine actually has a variable weight requirement for the counterweight block, that is, the low-speed section before the resonance speed (hereinafter referred to as the low-speed section) requires a small counterweight block, and the resonance speed and the high-speed section after the resonance speed require a large counterweight block.
[0071] It should be noted that the resonant speed in this embodiment is the speed at which the drum components (including the inner drum, outer drum, bearing system, shock absorption system, etc.) of the drum washing machine reach maximum vibration amplitude during the spin speed increase process. This usually corresponds to the natural frequency of the mechanical system.
[0072] Optionally, the resonant speed can be pre-calibrated, and the resonant speed of each washing machine or batch of washing machines can be measured and recorded through a standard test procedure on the factory production line and stored in the memory of the control unit. Optionally, the control system can run a short test procedure (for example, slowly increasing the speed under no load or standard load and monitoring vibration) at the beginning of the equipment use or at intervals of a preset time or a preset number of washes to automatically identify or update the current resonant speed. This can compensate for minor resonant speed drifts that may be caused by component aging, wear or load changes.
[0073] In this embodiment, the control unit continuously monitors the real-time speed information of the washing drum. When it detects that the speed information is lower than the resonant speed, the control unit sends an instruction to the adjustment device to reduce the effective weight of the counterweight block connected to the drum component, which helps to reduce the vibration amplitude in the low-speed section.
[0074] When the washing drum speed is detected to be greater than or equal to the resonant speed, the control unit sends a command to the adjustment device to increase the effective weight of the counterweight connected to the drum. By adding counterweight when approaching and reaching the resonant speed, the resonance peak is effectively suppressed, significantly reducing the maximum vibration amplitude during the spin cycle.
[0075] Reduce the counterweight at low speeds to meet Figure 2 The vibration characteristics shown help improve low-speed vibration performance and make the speed-up process smoother. By adopting different weight-balancing strategies in the low-speed and high-speed sections (especially the resonance zone), the vibration curve throughout the dehydration speed-up process is smoother, avoiding severe vibration peaks. The reduction in vibration amplitude directly leads to a decrease in noise level, improving user comfort.
[0076] In an optional embodiment, a method for determining the resonant speed of a drum component includes: obtaining a maximum weight value of a fully loaded counterweight; calculating a total weight of the drum component based on the maximum weight value; and determining the resonant speed based on the total weight.
[0077] It is understandable that the resonant rotation speed of the cylinder component is related to various factors such as the physical properties of the supporting structure (such as springs, dampers, and box structure) and the total weight of the cylinder component.
[0078] In this embodiment, the maximum weight of the fully loaded counterweight refers to the maximum weight that the adjustment device can apply to the counterweight. This is a design parameter that is determined at the time the equipment leaves the factory. Based on this maximum weight and the base weight (i.e., the weight of the inner and outer cylinders, bearings, and other fixed components), the total weight of the cylinder components can be calculated. The corresponding resonant speed can then be determined based on this total weight through design simulation, factory testing, or empirical formulas.
[0079] Depend on Figure 2It can be seen that the greater the weight of the counterweight block, the smaller the corresponding resonant speed, and the lower the vibration amplitude corresponding to the resonant speed. Therefore, in this embodiment, the resonant speed of the drum component is determined based on the maximum weight of the counterweight block, which helps to reduce the vibration amplitude of the drum component during the dehydration process.
[0080] In an optional embodiment, based on the dehydration stage and / or speed information, the control and adjustment device adjusts the weight of the counterweight block, including: when the dehydration stage is the eccentricity detection stage, the weighing stage or the pre-dehydration stage, the control and adjustment device adjusts the weight of the counterweight block to the minimum value; when the dehydration stage is the main dehydration stage, the control and adjustment device adjusts the weight of the counterweight block to the maximum value.
[0081] In this embodiment, the washing machine usually presets different speeds in different dehydration stages, such as the speed R1 corresponding to the eccentricity detection stage, the speed R2 corresponding to the weighing stage, the speed R3 corresponding to the pre-dehydration stage, the resonance speed R4, and the dehydration speed R5 corresponding to the main dehydration stage. The speeds satisfy R1<R2<R3<R4<R5, that is, R1, R2, and R3 all belong to the low-speed section before the resonance speed R4, and R5 belongs to the high-speed section after the resonance speed R4.
[0082] Before starting the three low-speed phases—eccentricity detection (R1), weighing (R2), and pre-release (R3)—the control system instructs the regulating shaft to adjust the weight of the counterweight to a minimum value. This can be achieved, for example, by draining all the liquid in the counterweight into a reservoir. This significantly reduces the weight of the counterweight by draining the liquid, helping to reduce vibration amplitude during the low-speed phase.
[0083] When the washing machine is about to continue to increase its speed from the pre-spin speed R3, is ready to cross the resonance speed R4, and finally reach the main spin speed R5, the control system instructs the adjustment device to adjust the weight of the counterweight block to the maximum value. For example, the weight of the counterweight block can be significantly increased by draining all the liquid in the liquid storage chamber into the counterweight block, thereby increasing the total weight of the entire drum component, which helps to reduce the vibration amplitude in the high-speed stage.
[0084] In an optional embodiment, the control method further includes: acquiring historical vibration information of the drum component, determining the vibration amplitude based on the historical vibration information, and adjusting the resonance speed based on the speed corresponding to the vibration amplitude.
[0085] Due to various factors, such as component aging, the resonant speed of a washing machine may change during use. In this case, controlling the machine based on the factory-set resonant speed may result in poor vibration reduction. In this embodiment, the laundry processing device incorporates adaptive learning capabilities, enabling the system to continuously optimize and adjust the resonant speed based on actual operating conditions, thereby improving the accuracy and robustness of vibration control.
[0086] During multiple spin cycles (or other processes involving high-speed spin phases), the vibration data of the washing drum (drum components) is continuously monitored and recorded. This historical vibration information should include a timestamp, the corresponding real-time rotational speed, and the vibration amplitude. This is typically achieved using a vibration sensor mounted on the washing machine casing or base. By analyzing this historical vibration data, the peak vibration data at the time of maximum amplitude can be determined. The rotational speed corresponding to this amplitude data is used as the washing machine's adjusted resonant speed, improving the accuracy of resonant speed identification, enhancing the adaptability of the control system, and optimizing the vibration reduction effect.
[0087] In an optional embodiment, before controlling the clothing processing equipment to enter the dehydration process in response to a preset program, the control method also includes: obtaining the operating stage of the clothing processing equipment; when the operating stage is the washing stage, controlling the adjustment device to reduce the weight of the counterweight block.
[0088] It is understandable that, since the rotation speed in the washing stage is usually low, even lower than the eccentricity detection speed, the adjustment device can be controlled to reduce the weight of the counterweight block and reduce the vibration amplitude in the low-speed stage.
[0089] In an alternative embodiment, reference Figure 3 As shown, the steps of the control method of the clothing processing equipment may include: after the washing is completed, the liquid in the counterweight block is discharged into the liquid storage chamber while the water is drained to reduce the weight of the drum component, and then the clothes are shaken and the speed is increased to R1 for eccentricity detection, after the eccentricity detection is qualified, the speed is increased to R2 for weighing detection, and then the speed is reduced to R1 for eccentricity detection before pre-dehydration, after the eccentricity detection is qualified, the speed is increased to R3 for pre-dehydration, after the pre-dehydration is completed, the speed is reduced to R1 for eccentricity detection, after the eccentricity detection is qualified, the speed is increased to R2 for weighing, and then the speed is reduced to R1 for eccentricity detection, and all the liquid in the liquid storage chamber is discharged into the counterweight block to increase the weight of the drum component, and after the eccentricity detection is qualified, the speed is increased and quickly crosses the resonance speed R4 and reaches the dehydration speed R5 for dehydration until the dehydration is completed.
[0090] In a second aspect, the present application provides a control device for a clothes processing device, referring to Figure 4 As shown, the drum component of the laundry processing device includes an outer drum and a washing drum located inside the outer drum. The outer drum is provided with a counterweight block and an adjusting device. The adjusting device is used to adjust the weight of the counterweight block. The control device includes:
[0091] The dehydration module 401 is used to control the clothes processing device to enter the dehydration process in response to a preset program;
[0092] An acquisition module 402 is used to acquire the dehydration stage of the clothes processing device and the rotation speed information of the washing drum;
[0093] The adjustment module 403 is used to control the adjustment device to adjust the weight of the counterweight based on the dehydration stage and / or rotation speed information.
[0094] The control device of this embodiment can be applied to clothing processing equipment and execute the control method of the clothing processing equipment of the above embodiment to optimize the vibration reduction effect of the clothing processing equipment. Its specific implementation method can refer to the above embodiment and will not be repeated in this embodiment.
[0095] In a third aspect, the present invention provides a clothing processing device, Figure 5 and Figure 6 As shown, it includes a housing 100, a drum component 200, an adjusting device 300 and a controller, the drum component 200 includes an outer drum 210 and a washing drum located inside the outer drum 210, and the outer drum 210 is provided with a counterweight 230; the adjusting device 300 is arranged on the housing 100 and connected to the counterweight 230, and is used to adjust the weight of the counterweight 230; the controller is electrically connected to the adjusting device 300 and the washing drum to execute the control method of the clothing processing device of the above embodiment.
[0096] In this embodiment, the housing 100 is the main outer shell of the laundry processing device, providing structural support and protection for the other components. The tub 200 comprises an outer tub 210 and a washing tub, which is mounted within the outer tub 210 via a rotating shaft and bearings. A port for mounting a counterweight 230 is provided on the outer tub 210. The tub 200 is suspended from the housing 100 by springs, and the bottom of the tub 200 is connected to the housing 100 via a damping vibration absorber. The springs cushion the vibration of the tub 200 and reduce the transmission of vibration loads from the tub 200 to the housing 100. The damping vibration absorber dissipates the vibration energy of the tub 200, reducing its vibration. The counterweight 230 increases the weight of the tub 200 and absorbs its vibration energy. The counterweight 230 effectively suppresses the vibration amplitude of the tub at resonant speeds and the vibration noise during high-speed spin cycles.
[0097] The main function of the counterweight 230 is to balance the centrifugal force generated by the washing drum and the clothes inside during high-speed rotation to prevent the equipment from vibrating violently and moving. In the present application, its weight is variable and can be adjusted by the adjusting device 300.
[0098] In an optional embodiment, there are multiple counterweight blocks 230, and the counterweight blocks 230 are formed with counterweight cavities 231; the adjusting device 300 includes a liquid storage cavity 310 and a liquid guide tube 320, one end of the liquid guide tube 320 is connected to the liquid storage cavity 310, and the other end is connected to the counterweight cavity 231 of at least one counterweight block 230.
[0099] In this embodiment, multiple counterweights 230 are mounted on the outer cylinder 210. At least one counterweight 230 has a counterweight chamber 231 disposed therein. The counterweight chamber 231 is used to contain a liquid, namely, counterweight liquid. A liquid storage chamber 310 is mounted on the housing 100 and serves as a central reservoir for the counterweight liquid. The liquid storage chamber 310 is connected to the counterweight chamber 231 via a liquid conduit 320. A drive unit, such as a water pump, transfers the counterweight liquid between the liquid storage chamber 310 and the counterweight chamber 231, thereby adjusting the weight of the counterweight 230.
[0100] Optionally, the weight of one of the counterweights 230, such as the counterweight 230 above the outer cylinder 210, can be adjusted by the adjusting device 300; it can also be designed to adjust the weight of multiple or all of the counterweights 230 through the adjusting device 300. The specific design can be made according to actual needs, and this embodiment does not make any specific restrictions on this.
[0101] In an optional embodiment, the counterweight 230 may include a first counterweight, a second counterweight and a third counterweight, wherein the first counterweight is installed above the outer cylinder 210, and the second counterweight and the third counterweight are installed on the left and right sides of the outer cylinder 210 respectively, that is, the first counterweight can adjust the vibration in the vertical direction, and the second counterweight and the third counterweight can be used to adjust the vibration in the horizontal direction.
[0102] In an optional embodiment, the control method of the clothing processing equipment may include: obtaining a first vibration amplitude in the horizontal direction and a second vibration amplitude in the vertical direction, and adjusting the weight of the counterweight blocks in the horizontal and vertical directions accordingly based on the first vibration amplitude and the second vibration amplitude.
[0103] For example, assume that there are counterweights in the system that primarily affect horizontal balance (e.g., the second and third counterweights installed on the left and right sides described previously). When it is detected that the amplitude of vibration in the horizontal direction is too large, the control system can: increase the weight of the two lateral counterweights (by feeding them with counterweight liquid) to increase the overall mass and inertia of the device, thereby improving stability against horizontal disturbances. Or, more precisely, it can be determined which direction (left or right) has the greater vibration, and attempt to offset part of the eccentricity effect by asymmetrically adjusting the weight of the counterweights on both sides, thereby improving the vibration reduction effect of the washing machine.
[0104] Figure 7 An example of a physical structure diagram of an electronic device is shown below. Figure 7As shown, the electronic device may include: a processor 701 (processor), a communication interface 702 (Communications Interface), a memory 703 (memory), and a communication bus 704. The processor 701, the communication interface 702, and the memory 703 communicate with each other via the communication bus 704. The processor 701 may call the logic instructions in the memory 703 to execute the steps of the control method of the clothing processing device.
[0105] In addition, the logic instructions in the above-mentioned memory 703 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when sold or used as an independent product.
