Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a washing machine control method and a washing machine. Background Technology

[0002] The working principle of a washing machine is to use a drive motor to drive the inner drum to rotate, and then use water and detergent to clean clothes.

[0003] During the spin-drying cycle, the washing machine's drive motor rotates at high speed to give the inner drum sufficient rotation speed to force the water out of the clothes through centrifugal force. In this process, the washing machine's core component, the bearing, needs to withstand the dual pressure from the drive motor and the weight of the clothes. Especially when the inner drum rotates at high speed, the pressure on the bearing increases, potentially leading to overload and bearing damage.

[0004] In existing technologies, some solutions select the appropriate spin-drying mode by detecting the weight of the clothes and control the drum speed accordingly. While these solutions can adapt to different load conditions to some extent, they do not provide a direct view of the pressure on the bearings, making it difficult to accurately determine the true load condition of the bearings. For example, when the clothes are unevenly distributed or the load changes dynamically, the bearings may be damaged due to overload operation, leading to equipment failure and affecting the lifespan and safety of the washing machine.

[0005] Therefore, there is an urgent need for a washing machine control method and a washing machine in order to solve the above problems. Summary of the Invention

[0006] Based on the above problems, the purpose of this invention is to provide a washing machine control method and a washing machine that can prevent bearing overload damage, extend the service life of the washing machine, and improve the overall operational stability of the washing machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] On the one hand, a washing machine control method is provided, wherein the washing machine includes a cabinet and an inner drum, and the inner drum is rotatably disposed in the cabinet via a rotating component;

[0009] The washing machine control method includes the following steps:

[0010] When the inner cylinder rotates, the current pressure value of the rotating component is detected;

[0011] When the current pressure value is less than or equal to a set pressure threshold, the target rotational speed of the inner cylinder is determined based on the current pressure value.

[0012] The inner cylinder is controlled to operate at the target rotational speed value.

[0013] During the garment processing, by monitoring the pressure on the rotating parts throughout the process and dynamically adjusting the inner drum speed, it is possible to prevent the rotating parts from operating under overload, avoid damage from overload, thereby improving the operational stability of the washing machine and extending the service life of the rotating parts.

[0014] As an optional embodiment of the washing machine control method of the present invention, the step of "determining the target rotational speed of the inner drum based on the current pressure value" includes:

[0015] Determine the pressure value range in which the current pressure value is located. There are multiple pressure value ranges, and each pressure value range corresponds to a target speed value.

[0016] The target rotational speed of the inner cylinder is determined based on the pressure range in which the current pressure value falls.

[0017] Multiple pressure value ranges and corresponding target speeds can be pre-stored in the washing machine's control system. When the current pressure value of the rotating component is obtained, the specific pressure value range can be determined by comparison, which means the target speed value of the inner drum corresponding to that pressure value range can be determined, and the inner drum can be controlled to adjust its speed to the target speed.

[0018] As an optional embodiment of the washing machine control method of the present invention, the plurality of pressure value ranges include: (P1) min P1 max ), (P2 min P2 max ), ..., (Pn min Pn max The target rotational speed values ​​include: V1, V2, ..., Vn;

[0019] Each of the target rotational speed values ​​corresponds one-to-one with a plurality of pressure value ranges, with the pressure values ​​of the plurality of pressure value ranges increasing sequentially and the plurality of target rotational speed values ​​decreasing sequentially.

[0020] When the washing machine is under heavy load, the rotating parts bear greater pressure. Lowering the drum speed can reduce this pressure and prevent overloading. Conversely, when the washing machine is operating under low load, the rotating parts bear less pressure. Increasing the drum speed can improve clothing processing efficiency.

[0021] As an optional embodiment of the washing machine control method of the present invention, the current pressure value of the rotating component is detected once every first time interval t1;

[0022] The current pressure value is greater than the maximum pressure value Pn in the current pressure value range. max At that time, reduce the rotational speed of the inner cylinder; and / or,

[0023] The current pressure value is less than the minimum pressure value Pn in the current pressure value range. min At that time, increase the rotational speed of the inner cylinder.

[0024] As an optional embodiment of the washing machine control method of the present invention, the step of "reducing the rotation speed of the inner drum" includes:

[0025] The rotational speed of the inner cylinder is adjusted to the target rotational speed value corresponding to the next pressure value range of the current pressure value range.

[0026] As an optional embodiment of the washing machine control method of the present invention, the step of "increasing the rotation speed of the inner drum" includes:

[0027] The rotational speed of the inner cylinder is adjusted to the target rotational speed value corresponding to the previous pressure value range of the current pressure value range.

[0028] As an optional embodiment of the washing machine control method of the present invention, the washing machine further includes a detection component;

[0029] The detection component is disposed on the rotating component and is used to detect the pressure borne by the rotating component; or, the washing machine further includes a support structure, the rotating component is disposed on the support structure, and the detection component is disposed at the position where the support structure and the rotating component are connected, for detecting the pressure borne by the rotating component.

[0030] By placing the detection component on the rotating component, the pressure on the rotating component can be directly measured, resulting in more accurate detection results. This allows for more precise adjustment of the inner cylinder speed, ensuring that the inner cylinder maintains its optimal operating condition without overloading the rotating component.

[0031] As an optional embodiment of the washing machine control method of the present invention, the rotating component includes a bearing and / or a rotating shaft, and the detection component is disposed on the bearing or the rotating shaft;

[0032] And / or, multiple detection components are provided on the rotating component, and the current pressure value is the average of the detection values ​​of the multiple detection components.

[0033] By averaging the data collected from multiple detection components as the current pressure value of the rotating component, detection errors can be reduced, and the accuracy of the detection results can be improved. This more accurately reflects the actual pressure borne by the rotating component, avoiding misadjustments caused by fluctuations in single-point data, ensuring that the rotating component is never overloaded, and that the inner drum's rotation speed is appropriate. Furthermore, the design of multiple detection components provides redundancy, preventing system malfunction due to the failure of a single detection component, thus improving the overall operational reliability of the washing machine.

[0034] As an optional embodiment of the washing machine control method of the present invention, the washing machine control method further includes the following steps:

[0035] When the current pressure value of the rotating component detected is greater than the set pressure threshold, the current clothes processing program is stopped, and the washing machine is controlled to issue a prompt message.

[0036] And / or, within a second time period t2 after the start of the garment processing procedure, the inner drum is controlled to operate at an initial speed value, which is less than the target speed value.

[0037] On the other hand, a washing machine is provided, which is controlled by the washing machine control method described above. The washing machine includes a cabinet and an outer drum and an inner drum disposed in the cabinet, wherein the inner drum is rotatably disposed in the outer drum.

[0038] The washing machine also includes a control module, which controls the rotation of the inner drum according to the clothing processing program and the pressure value of the rotating component.

[0039] The beneficial effects of this invention are as follows:

[0040] The washing machine control method and washing machine provided by this invention, when the inner drum rotates, detect the pressure borne by rotating components (such as bearings, shafts, etc.) and determine the target rotation speed of the inner drum based on the current pressure value of the rotating components. This allows the inner drum to operate at a suitable rotation speed, thereby preventing excessive rotation speed from overloading the rotating components. During the execution of the clothing processing program (such as the spin-drying program), by continuously monitoring the pressure borne by the rotating components and dynamically adjusting the rotation speed of the inner drum, overload operation of the rotating components can be prevented, avoiding damage to the rotating components due to overload, thereby improving the operational stability of the washing machine and extending the service life of the rotating components.

[0048] Example 1

[0049] This embodiment provides a washing machine control method that can prevent bearing overload damage, extend the service life of the washing machine, and improve the overall operational stability of the washing machine. The washing machine includes a cabinet and an inner drum, with the inner drum rotatably mounted within the cabinet via a rotating component.

[0050] like Figure 1 As shown, the washing machine control method includes the following steps:

[0051] S1. When the inner cylinder rotates, detect the current pressure value of the rotating parts;

[0052] S2. When the current pressure value is less than or equal to the set pressure threshold, determine the target rotational speed of the inner cylinder based on the current pressure value;

[0053] S3. Control the inner cylinder to run at the target speed value.

[0054] The washing machine control method provided in this embodiment detects the pressure on rotating components (such as bearings and shafts) during drum rotation and determines the target rotation speed of the drum based on the current pressure value. This ensures the drum operates at a suitable speed, preventing overload of the rotating components due to excessive drum rotation. During the garment processing program (such as the spin-drying program), by continuously monitoring the pressure on the rotating components and dynamically adjusting the drum speed, overload damage to the rotating components is prevented, thus improving the washing machine's operational stability and extending the service life of the rotating components.

[0055] like Figure 2 As shown, in step S2, the step of "determining the target rotational speed of the inner cylinder based on the current pressure value" includes:

[0056] S21. Determine the pressure value range where the current pressure value is located. There are multiple pressure value ranges, and each pressure value range corresponds to a target speed value.

[0057] S22. Determine the target rotational speed of the inner cylinder based on the pressure range in which the current pressure value is located.

[0058] Multiple pressure value ranges and corresponding target speeds can be pre-stored in the washing machine's control system. When the current pressure value of the rotating component is obtained, the specific pressure value range can be determined by comparison, which means the target speed value of the inner drum corresponding to that pressure value range can be determined, and the inner drum can be controlled to adjust its speed to the target speed value.

[0059] Dynamically adjusting the drum's rotation speed based on the current pressure range ensures that the pressure on rotating components remains within acceptable limits, preventing them from operating under excessive loads, reducing wear and tear, minimizing malfunctions, and extending their lifespan. Simultaneously, dynamically adjusting the drum's rotation speed based on the pressure on the rotating components reduces vibration caused by unbalanced loads, lowers noise, and improves the washing machine's operational stability. For example, during the spin cycle, a higher detected pressure indicates a higher load on the drum; operating the drum at a lower speed avoids strong vibrations caused by excessive speed and prevents overload, ensuring smooth operation and improved safety. Conversely, a lower detected pressure indicates a lower load on the drum; operating the drum at a slightly higher speed improves spin-drying efficiency, shortens spin-drying time, and enhances user experience and product competitiveness.

[0060] In this embodiment, multiple pressure value ranges include: (P1) min P1max ), (P2 min P2 max ), ..., (Pn min , Pn max The target rotational speed values ​​include: V1, V2, ..., Vn. Each target rotational speed value corresponds one-to-one with a pressure range, with the pressure values ​​in each range increasing sequentially and the target rotational speed values ​​decreasing sequentially. That is, when the current pressure value of the rotating component is high, the rotational speed of the inner cylinder is reduced accordingly to prevent the pressure on the rotating component from continuously increasing, thereby preventing overload damage to the rotating component.

[0061] For example, when the washing machine is under heavy load, the rotating parts bear greater pressure. Appropriately lowering the inner drum's speed can reduce the pressure on the rotating parts and prevent overloading. When the washing machine is running under low load, the rotating parts bear less pressure. Appropriately increasing the inner drum's speed can improve the efficiency of handling clothes.

[0062] For example, the multiple pressure value ranges can be: (10N, 30N), (30N, 50N), (50N, 90N), (90N, 130N), (130N, 170N), (170N, 210N), (210N, 250N), (250N, 300N), (300N, 350N), (350N, 400N), (400N, 450N), (450N, 500N), (500N, 600N), (600N, 800N).

[0063] Multiple target speed values ​​are available: 1200rpm, 1100rpm, 1000rpm, 950rpm, 900rpm, 850rpm, 800rpm, 750rpm, 700rpm, 650rpm, 600rpm, 550rpm, 500rpm, and 400rpm.

[0064] The pressure range and corresponding target speed value mentioned above can be set according to the washing machine model, and are not limited to the specific range and speed value listed above.

[0065] Optionally, the set pressure threshold for the rotating parts is selected according to the specifications of the washing machine. For example, for household washing machines, the set pressure threshold is between several hundred and several thousand Newtons, such as 1kN, 5kN, 8kN, etc., and is not limited to the values ​​listed above. For industrial washing machines, the set pressure threshold is above several thousand Newtons, such as 10kN, 15kN, 20kN, etc., and is not limited to the values ​​listed above.

[0066] Optionally, the washing machine also includes a detection component, which is disposed on the rotating component and is used to detect the pressure exerted on the rotating component. By placing the detection component on the rotating component, the pressure exerted on the rotating component can be measured directly, resulting in more accurate detection results. This allows for more precise adjustment of the inner drum speed, ensuring that the inner drum maintains optimal operating conditions without overloading the rotating component.

[0067] Optionally, multiple detection components are installed on the rotating component, and the current pressure value is the average of the detection values ​​from multiple components. Using the average of the data collected by multiple detection components as the current pressure value of the rotating component reduces detection errors and improves the accuracy of the detection results. This more accurately reflects the actual pressure borne by the rotating component, avoids misadjustments caused by fluctuations in single-point data, ensures that the rotating component is never overloaded, and that the inner drum's rotation speed is appropriate. Simultaneously, the design of multiple detection components provides redundancy, preventing system malfunction due to the failure of a single detection component, thus improving the overall operational reliability of the washing machine.

[0068] For example, the detection component can be a pressure sensor. For instance, the detection component can be a strain gauge sensor, which offers high detection accuracy and fast response; or, the detection component can be a piezoelectric sensor, which offers high sensitivity and good dynamic response.

[0069] Optionally, the rotating components include bearings and / or shafts, and the detection component is mounted on the bearing or shaft. In some embodiments, the detection component can be mounted on the bearing to directly detect the pressure borne by the bearing, enabling real-time monitoring of the bearing's operating status and dynamically adjusting the inner cylinder speed based on the detected bearing pressure to ensure the safe operation of the bearing.

[0070] In other implementations, the detection component can be mounted on the rotating shaft, specifically at the position where the shaft mates with the bearing. This allows for real-time monitoring of the pressure on the bearing, enabling dynamic adjustment of the inner cylinder's rotation speed based on the pressure, preventing bearing overload damage and extending its service life. The rotating shaft can be the output shaft of a drive motor, or it can be connected to the output end of a drive motor.

[0071] Optionally, such as Figure 3 As shown, during the garment processing procedure, the current pressure value of the rotating component is checked every first time interval t1. The current pressure value is greater than the maximum pressure value Pn within its current pressure value range. max At that time, reduce the rotation speed of the inner cylinder.

[0072] In other words, if the detected pressure value of the rotating component increases during washing machine operation and exceeds the initially selected pressure range, it indicates that the rotating component is at risk of overload. Reducing the drum speed helps decrease the pressure on the rotating component, keeping it within the allowable range and effectively preventing damage from overload. Simultaneously, it reduces vibration and noise caused by excessive load, improving the user experience.

[0073] Optionally, the above-mentioned step of "reducing the rotation speed of the inner cylinder" includes:

[0074] Adjust the rotational speed of the inner cylinder to the target rotational speed value corresponding to the next pressure value range in the current pressure value range.

[0075] Specifically, when the pressure on the rotating component gradually increases and exceeds the current pressure range, it indicates that the current rotational speed of the inner cylinder is too high, which may cause the rotating component to overload. Therefore, adjusting the rotational speed of the inner cylinder to the target rotational speed value corresponding to the next pressure range, that is, reducing the rotational speed of the inner cylinder by one level, can reduce the pressure on the rotating component and effectively avoid the problem of overloading the rotating component.

[0076] For example, the first duration t1 can range from 5 seconds to 60 seconds to ensure real-time detection. For instance, the first duration t1 can be 5 seconds, 6 seconds, 8 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds, etc., but is not limited to the values ​​and ranges listed above.

[0077] Example 2

[0078] This embodiment provides a washing machine control method, which is a further improvement on Embodiment 1:

[0079] Optionally, such as Figure 3 As shown, during the garment processing procedure, the current pressure value of the rotating component is checked every first time interval t1. The pressure value is determined when the current pressure value is less than the minimum pressure value Pn within its current pressure value range. min At that time, increase the rotation speed of the inner cylinder.

[0080] In other words, if the detected pressure value of the rotating component decreases during washing machine operation and falls outside the initially selected pressure range, it indicates that the rotating component is not at risk of overload. The drum speed can then be appropriately increased to fully utilize the power of the drive mechanism, avoid inefficient operation, improve clothing processing efficiency, shorten processing time, and prevent damage to the rotating component. Furthermore, this control method achieves intelligent control of the drum speed, eliminating the need for manual intervention and providing a better user experience.

[0081] Optionally, the above-mentioned step of "increasing the rotation speed of the inner cylinder" includes:

[0082] Adjust the rotational speed of the inner cylinder to the target rotational speed value corresponding to the previous pressure value range within the current pressure value range.

[0083] Specifically, when the pressure on the rotating component gradually decreases and the current pressure value is no longer within the selected current pressure value range, it indicates that the load that the rotating component can withstand still has room for increase. Therefore, adjusting the rotation speed of the inner drum to the target rotation speed value corresponding to the previous pressure value range, that is, increasing the rotation speed of the inner drum by one level, can improve the efficiency of clothing processing while ensuring that the rotating component is not overloaded.

[0084] For example, the first duration t1 can range from 5 seconds to 60 seconds to ensure real-time detection. For instance, the first duration t1 can be 5 seconds, 6 seconds, 8 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, 30 seconds, 35 seconds, 40 seconds, 45 seconds, 50 seconds, 55 seconds, 60 seconds, etc., but is not limited to the values ​​and ranges listed above.

[0085] Example 3

[0086] This embodiment provides a washing machine control method, which differs from Embodiment 1 in that:

[0087] Optionally, the washing machine also includes a support structure and a detection component. The rotating component is mounted on the support structure, and the detection component is located at the connection between the support structure and the rotating component to detect the pressure borne by the rotating component. The support structure can be a support frame for mounting the inner drum. The rotating component includes a bearing, with the outer ring of the bearing fixedly connected to the support frame. Positioning the detection component at the location where the support frame and the outer ring of the bearing are fixedly connected allows for real-time monitoring of the pressure borne by the bearing. Furthermore, mounting the detection component on the support structure provides flexible installation.

[0088] Optionally, multiple detection components are installed at the connection point between the support structure and the rotating component. The current pressure value is the average of the detection values ​​from multiple components. Using the average of the data collected by multiple detection components as the current pressure value of the rotating component reduces detection errors and improves the accuracy of the detection results. This more accurately reflects the actual pressure borne by the rotating component, avoids misadjustments caused by fluctuations in single-point data, ensures that the rotating component is never overloaded, and that the inner drum's rotation speed is appropriate. Simultaneously, the design of multiple detection components provides redundancy, preventing system malfunction due to the failure of a single detection component, thus improving the overall operational reliability of the washing machine.

[0089] For example, the detection component can be a pressure sensor. For instance, the detection component can be a strain gauge sensor, which offers high detection accuracy and fast response; or, the detection component can be a piezoelectric sensor, which offers high sensitivity and good dynamic response.

[0090] Example 4

[0091] This embodiment provides a washing machine control method, which is a further improvement on Embodiment 1 or Embodiment 2:

[0092] In this embodiment, the washing machine control method further includes the following steps:

[0093] When the current pressure value of the detected rotating part exceeds the set pressure threshold, the current clothes processing program is stopped, and the washing machine is controlled to issue a prompt message.

[0094] When the pressure value detected by the detection component exceeds the set pressure threshold, the user is promptly alerted to the washing machine's status and is given appropriate measures to prevent overload operation, avoid washing machine malfunctions and damage, reduce the probability of repairs, maintain the washing machine in good condition, and extend its service life.

[0095] For example, an alarm module can be set up in the washing machine. When the pressure value detected by the detection component exceeds the set pressure threshold, the clothes processing program will not be executed, and the alarm module will issue an alarm to prompt the user to clear the fault, thereby avoiding damage to the rotating parts and improving the operational safety of the washing machine.

[0096] The alarm module can provide alerts in various forms, including sound alerts, visual alerts, vibration alerts, mobile phone notifications, light alerts, graphic alerts, and voice assistant alerts. For example, it can alert the user by emitting a buzzer sound; or by using pre-recorded voice messages; or by using LEDs of different colors and flashing patterns to alert the user, or by displaying error codes or text messages on the display panel; it can also send SMS reminders to the user, and so on.

[0097] Optionally, the washing machine control method further includes the following steps:

[0098] During the second time period t2 after the start of the garment processing procedure, the inner drum is controlled to run at an initial speed value, which is less than the target speed value.

[0099] During the initial period of washing machine operation, controlling the inner drum to run at a lower speed can balance the load and reduce vibration and noise generated during high-speed spin drying. At the same time, low-speed start-up can avoid overloading the drive mechanism and rotating parts, improve operational safety, extend the service life of the equipment, and improve the user experience.

[0100] Optionally, the initial speed value can be in the range of 100 rpm to 400 rpm. For example, the initial speed value can be 100 rpm, 150 rpm, 200 rpm, 250 rpm, 300 rpm, 400 rpm, etc., and is not limited to the values ​​and ranges listed above.

[0101] Optionally, the second duration t2 can range from 1 minute to 10 minutes, allowing sufficient buffer time. For example, the second duration t2 can be 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, 10 minutes, etc., but is not limited to the values ​​and ranges listed above.

[0102] Optionally, the washing machine control method further includes the following steps:

[0103] Before executing the garment processing procedure, initialize the rotation speed of the inner drum and the detection values ​​of the detection components.

[0104] Before each program execution, the existing data is initialized to prevent residual data from the previous run from affecting the execution of the current program, reduce detection errors, ensure the accuracy of detection data, and thus accurately adjust the inner drum speed according to the actual situation, prevent overload of rotating parts, and improve the operational stability of the washing machine.

[0105] Example 5

[0106] This embodiment provides a washing machine controlled using the washing machine control method of any of the above embodiments. The washing machine includes a cabinet and an outer drum and an inner drum disposed within the cabinet, with the inner drum rotatably disposed within the outer drum. The washing machine also includes a control module, which controls the rotation of the inner drum based on the clothing processing program and the pressure value of the rotating components. The control module may be a control computer board for the washing machine, on which the control program corresponding to the aforementioned washing machine control method is integrated.

[0107] The washing machine provided in this embodiment detects the pressure on rotating components (such as bearings and shafts) during drum rotation and determines the target rotation speed of the drum based on the current pressure value. This ensures the drum operates at a suitable speed, preventing overload of the rotating components due to excessive drum rotation. During the garment processing program (such as the spin-drying program), by continuously monitoring the pressure on the rotating components and dynamically adjusting the drum speed, overload damage to the rotating components is prevented, thus improving the washing machine's operational stability and extending the service life of the rotating components.

[0108] In some embodiments, the washing machine further includes a data processing module. During the washing machine's garment processing program, the data processing module records key parameters, such as the maximum pressure value and average pressure value detected by the detection components. The garment processing program can then be optimized based on the data stored in the data processing module, providing a reference for the optimized design of the washing machine. Furthermore, the data recorded by the data processing module can be displayed on the washing machine's display panel for user viewing, helping the user understand the device's operating status.
