[0001] This invention is a divisional application of Chinese patent application No. 201911055062.1, filed on October 31, 2019, entitled "Control Method and Apparatus for Clothing Processing Device". Technical Field

[0002] This application relates to the field of household appliance technology, and in particular to a control method and apparatus for a clothing handling device. Background Technology

[0003] Currently, with the advent of drumless or semi-external drum washing machines, the problem of dirt accumulation between the inner and outer drums during the washing process has been solved. Compared with the traditional design of washing machines, drumless or semi-external drum washing machines can achieve the goals of increasing capacity and saving water.

[0004] However, in actual washing processes, when there is a high water level and low load, the agitation of the impeller and the poor coverage of the clothes can result in excessive splashing. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, this application proposes a control method for a clothing processing device to avoid the problem of excessive water splashing during the washing process when the water level is high and the load is low.

[0007] The first aspect of this application provides a control method for a clothing handling device, including: Determine whether the water level of the garment processing device is the target water level; if the distance between the target water level and the overflow port of the garment processing device is less than a threshold distance; if the water level is the target water level, then detect the load applied to the impeller during the operation of the impeller of the garment processing device to obtain a load indication value. If the load indication value is determined to be less than a first threshold, the operating cycle intensity is reduced, and the clothing processing device is controlled to execute the reduced operating cycle intensity during the washing process.

[0008] As a first possible implementation of this application embodiment, the step of detecting the load applied to the impeller during the operation of the garment processing device and obtaining a load indication value includes: For the fixed-frequency motor that drives the impeller, determine the back electromotive force pulse value generated when the impeller continues to run after the fixed-frequency motor is powered off; The load indication value is determined based on the back electromotive force pulse value.

[0009] As a second possible implementation of this application embodiment, the step of detecting the load applied to the impeller during the operation of the garment processing device and obtaining a load indication value includes: For the variable frequency motor that drives the impeller, determine the power of the variable frequency motor to drive the impeller. The load indication value is determined based on the power.

[0010] As a third possible implementation of this application embodiment, the step of determining that the load indication value is less than a first threshold and reducing the operating cycle intensity includes: If the load indication value is less than the first threshold and greater than the second threshold, then the load is reduced from the standard beat corresponding to the target water level to the first beat; wherein the second threshold is less than the first threshold. If the load indication value is less than or equal to the second threshold, the cycle time will decrease from the standard cycle time corresponding to the target water level to the second cycle time; the intensity of the second cycle time is less than that of the first cycle time.

[0011] As a fourth possible implementation of this application, after detecting the load applied to the impeller during the operation of the garment processing device and obtaining the load indication value, the method further includes: If the load indication value is determined to be greater than or equal to the first threshold, the clothing processing device is controlled to execute the standard rhythm corresponding to the target water level.

[0012] As a fifth possible implementation of this application embodiment, after determining whether the water level of the clothing treatment device is the target water level, the method further includes: If the water level is not the target water level, the garment processing device is controlled to execute the standard cycle corresponding to the water level during the washing process.

[0013] The control method of the clothing handling device in this application embodiment determines whether the water level of the clothing handling device is at the target water level. When the water level is at the target water level, the method detects the load applied to the impeller during the operation of the impeller of the clothing handling device to obtain a load indication value. If the load indication value is determined to be less than a first threshold, the method reduces the operating cycle intensity and controls the clothing handling device to execute the reduced operating cycle intensity during the washing process. This method, when the clothing handling device is at a high water level and low load, reduces the operating cycle intensity during the washing process to execute a weaker operating cycle, avoiding the situation where a high operating cycle intensity during a high water level and low load would cause excessive water splashing from the overflow port, thus achieving the purpose of reducing splashing.

[0014] A second aspect of this application provides a control device for a garment handling apparatus, comprising: The judgment module is used to determine whether the water level of the clothing processing device is the target water level; the distance between the target water level and the overflow port of the clothing processing device is less than a threshold distance; The detection module is used to detect the load applied to the impeller during the operation of the impeller of the clothing processing device when the water level is the target water level, and obtain the load indication value. The control module is used to determine that the load indication value is less than a first threshold, reduce the operating cycle intensity, and control the clothing processing device to execute the reduced operating cycle during the washing process.

[0015] The control device of the garment handling apparatus in this application embodiment determines whether the water level of the garment handling apparatus is at the target water level. If the water level is at the target water level, it detects the load applied to the impeller during the operation of the impeller and obtains a load indication value. If the load indication value is determined to be less than a first threshold, the operating cycle intensity is reduced, and the garment handling apparatus is controlled to execute the reduced-intensity operating cycle during the washing process. This method reduces the operating cycle intensity during the washing process when the garment handling apparatus is at a high water level and low load, thus avoiding the situation where a high operating cycle intensity during a high water level and low load results in excessive water splashing from the overflow port, achieving the purpose of reducing splashing.

[0016] A third aspect of this application provides a garment handling apparatus, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the control method described in the above embodiments.

[0017] The fourth aspect of this application provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the control method as described in the above embodiments.

[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0019] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 A schematic flowchart illustrating a control method for a garment processing device provided in an embodiment of this application; Figure 2 A schematic flowchart illustrating a control method for another garment handling apparatus provided in an embodiment of this application; Figure 3This is a schematic diagram of the structure of a control device for a garment processing apparatus provided in an embodiment of this application. Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] When using a washing machine with a garment handling device, taking a top-loading washing machine without an outer tub or with only a half-outer tub as an example, when the water level is high and the load is low during the washing process, the agitation of the pulsator causes a lot of water to splash out of the overflow port from the washing tub.

[0022] To address the aforementioned problems, this application proposes a control method for a clothing handling device. By determining whether the water level in the clothing handling device is at the target water level, and if so, detecting the load applied to the impeller during operation to obtain a load indication value; and determining that the load indication value is less than a first threshold, reducing the operating cycle intensity and controlling the clothing handling device to execute the reduced-intensity operating cycle during the washing process. Thus, when the clothing handling device is at a high water level and low load, a weaker washing cycle is selected for reduced-intensity washing, achieving the goal of reducing water splashing during the washing process.

[0023] The control method and apparatus of the garment processing device according to embodiments of this application are described below with reference to the accompanying drawings.

[0024] Figure 1 This is a schematic flowchart illustrating a control method for a garment processing device provided in an embodiment of this application.

[0025] like Figure 1 As shown, the control method includes the following steps: Step 101: Determine whether the water level of the clothing processing device is the target water level.

[0026] Specifically, the distance between the target water level and the overflow outlet of the laundry treatment device is less than the threshold distance. For example, the distance between the target water level and the overflow outlet of the laundry treatment device is 4 centimeters.

[0027] As an example, the clothing processing device in this application embodiment can be a top-loading washing machine without an outer tub, or a top-loading washing machine with a half-outer tub, etc.

[0028] In this embodiment of the application, before the washing process is executed, after detecting that the clothes to be washed are placed in the washing tub of the clothes handling device, the water inlet valve of the clothes handling device is opened to fill the clothes handling device with water. After the water filling is completed, it is determined whether the water level in the washing tub of the clothes handling device is the target water level.

[0029] As one possible implementation, the laundry handling device can automatically control the water inlet valve to open and inject water after detecting that the user has put the clothes to be washed into the washing tub.

[0030] As another possible implementation, after detecting that the clothes to be washed are placed in the washing tub of the clothes handling device, the clothes handling device detects the water level selected by the user and, in response to the user's operation, controls the water inlet valve to open to fill the clothes handling device with water.

[0031] Step 102: If the water level is the target water level, then detect the load applied to the impeller during the operation of the clothing processing device and obtain the load indication value.

[0032] In one possible scenario, after the water filling process of the garment handling device is completed, if it is determined that the water level of the garment handling device is not the target water level, then the garment handling device will execute the standard cycle corresponding to the water level during the washing process to complete the washing process.

[0033] Understandably, if the target water level is high, and the water level in the garment processing device is not high, the water in the washing tub will not overflow from the overflow port or the overflow amount will be small during the washing process. In this case, the garment processing device can be controlled to execute the standard cycle corresponding to the water level during the washing process.

[0034] In another possible scenario, the water filling of the garment handling device is completed, and the water level of the garment handling device is determined to be the target water level. In this case, the water level in the washing tub is the high water level. After the garment handling device has finished filling, the clothes to be washed in the washing tub are completely wet. The wet clothes in the washing tub are weighed to determine the load status of the garment handling device, so as to determine the operating cycle intensity during the washing process based on the load of the garment handling device.

[0035] In this embodiment, the load applied to the impeller during the operation of the garment handling device can be detected to obtain a load indication value. In other words, by detecting the load applied to the impeller during operation, the weight of the wet clothes after water intake can be fed back based on the load indication value. For example, the weight of the wet clothes can be measured based on the pulses or power of the impeller drive motor.

[0036] The load indication value corresponds to different loads. For example, it can be high load, medium load, and low load. As an example, a high load corresponds to a load of 8-12 kg of laundry, while a low load corresponds to a load of 1-6 kg. Each load of the laundry handling unit has a corresponding inlet water level and washing cycle to achieve the corresponding washing performance. Typically, a high load corresponds to a high inlet water level and a high-intensity washing cycle, while a low load corresponds to a low inlet water level and a low-intensity washing cycle.

[0037] As one possible implementation, the load indication value can be the back electromotive force (EMF) pulse value generated when the impeller continues to operate after the power is cut off from the fixed-frequency motor. In this case, the load indication value can be determined based on the back EMF pulse value generated when the impeller continues to operate after the power is cut off from the fixed-frequency motor driving the impeller. For example, when driving the fixed-frequency motor to turn on and off, a set of back EMF pulse values ​​will be generated after the fixed-frequency motor stops rotating after the power is cut off. The load indication value can be determined by reading the back EMF pulse values ​​through the garment handling device.

[0038] As another possible implementation, the load indication value applied to the impeller during impeller operation can be the power of the variable frequency motor driving the impeller. In this case, the load indication value can be determined based on the power of the variable frequency motor driving the impeller, by detecting the power of the variable frequency motor driving the impeller.

[0039] For example, during the washing process, when determining the weight of wet clothes based on the power of the variable frequency motor driving the pulsator, information such as the first total power of the variable frequency motor driving the pulsator during the speed increase phase, the second total power during the stable washing phase, and the average torque fluctuation value of the pulsator rotation during the stable washing phase can be obtained. Specifically, the first total power is the power of the variable frequency motor accumulating when the pulsator rotates once, starting from the point where the variable frequency motor reaches the first speed. The second total power is the power of the variable frequency motor accumulating m rotations of the pulsator when it reaches the second speed during the washing phase. The third total power is the power of the variable frequency motor driving the pulsator to rotate a second number of times during the washing process, when the variable frequency motor is stable at the second speed. During the stable washing phase, by obtaining the rotational fluctuation value of the variable frequency motor per rotation of the washing tub and the total number of rotations of the washing tub, the average torque fluctuation value can be calculated.

[0040] Furthermore, calculate the weight of the wet clothes in the washing tub using the following formula: f(G)=K1*(P1 / m+K2*P2 / n)+K3*P1*P2 / T0 Where f(G) is the weight of the wet clothes after water enters the washing tub; P1 is the first total power; P2 is the second total power; m is the first number of revolutions; n is the second number of revolutions; T0 is the average torque fluctuation value; K1, K2, and K3 are inertia constants.

[0041] Step 103: Determine that the load indication value is less than the first threshold, reduce the operating cycle intensity, and control the garment handling device to execute the reduced operating cycle during the washing process.

[0042] In this embodiment of the application, the first threshold can be the maximum value of the clothes to be washed in the set clothes processing device being in a low load state.

[0043] In one possible scenario, the load applied to the impeller during the operation of the garment handling unit is detected. After obtaining the load indication value, it is determined that the load indication value is less than a first threshold. In this case, the garment handling unit is in a high water level, low load state. The unit can be controlled to reduce its operating cycle intensity and execute the reduced cycle intensity during the washing process. Thus, by reducing the operating cycle intensity during the high water level, low load state, the goal of reducing water splashing during the washing process is achieved.

[0044] The control method of the clothing handling device in this application embodiment determines whether the water level of the clothing handling device is at the target water level. If the water level is at the target water level, the load applied to the impeller during the operation of the impeller of the clothing handling device is detected to obtain a load indication value. If the load indication value is determined to be less than a first threshold, the operating cycle intensity is reduced, and the clothing handling device is controlled to execute the reduced-intensity operating cycle during the washing process. This method reduces the operating cycle intensity when the clothing handling device is at the target water level and the load indication value is less than the first threshold, thereby executing a weaker operating cycle during the washing process. This avoids the situation where a high operating cycle intensity during high water level and low load leads to excessive splashing, thus achieving the purpose of reducing splashing.

[0045] Based on the above embodiments, after obtaining the load indication value, the intensity of reducing the operating cycle can be determined according to the load indication value, so that different loads can be executed with corresponding operating cycle intensities for the washing process. The following is in conjunction with... Figure 2 The above process will be described in detail. Figure 2 A schematic flowchart illustrating a control method for another garment handling apparatus provided in an embodiment of this application.

[0046] like Figure 2 As shown, the control method may further include the following steps: Step 201: Detect the load applied to the impeller during the operation of the garment processing device and obtain the load indication value.

[0047] In this embodiment, the implementation process of step 201 can be referred to the implementation process of step 102 in the above embodiment, and will not be repeated here.

[0048] Step 202: Determine whether the load indicator value is less than the first threshold.

[0049] Step 203: If the load indication value is determined to be greater than or equal to the first threshold, then control the clothing processing device to execute the standard cycle corresponding to the target water level.

[0050] In this embodiment, the load applied to the impeller during the operation of the garment processing device is detected. After obtaining the load indication value, it is determined that the load indication value is greater than or equal to a first threshold. In this case, the current washing state of the garment processing device can be determined to be high water level and high load. During the washing process, the garment processing device is controlled to execute the standard cycle corresponding to the target water level.

[0051] Step 204: If the load indicator value is less than the first threshold, determine whether the load indicator value is greater than the second threshold.

[0052] In this embodiment of the application, the load applied to the impeller during the operation of the garment processing device is detected. After obtaining the load indication value, it is determined that the load indication value is less than a first threshold. Further, it is determined whether the load indication value is greater than a second threshold.

[0053] The second threshold is less than the first threshold.

[0054] Step 205: If the load indication value is less than the first threshold and greater than the second threshold, reduce the load from the standard beat corresponding to the target water level to the first beat.

[0055] In one possible scenario, if the load indication value is determined to be less than a first threshold and greater than a second threshold, then the current washing state of the garment handling device can be determined to be high water level with low load. To reduce water splashing during the washing process, the garment handling device can be controlled to reduce its operating cycle intensity from the standard cycle corresponding to the target water level to the first cycle.

[0056] Step 206: Determine that the load indication value is less than or equal to the second threshold, and reduce the load from the standard beat corresponding to the target water level to the second beat.

[0057] The intensity of the second beat is less than that of the first beat.

[0058] In one possible scenario, if the load indication value is determined to be less than a second threshold, the current washing state of the garment handling device can be determined to be high water level, low load. To reduce water splashing during the washing process, the garment handling device can be controlled to reduce its operating cycle intensity from the standard cycle corresponding to the target water level to the second cycle.

[0059] Understandably, the load indicator value is used to provide feedback on the weight of the clothes to be washed in the washing tub. When the load indicator value is low, the weight of the clothes to be washed in the washing tub is low. Under high water level and low load conditions, during the washing process, when the impeller drives the clothes to rotate, in order to reduce water splashing, the operating cycle intensity of the clothes handling device can be reduced from the standard cycle corresponding to the target water level to a second cycle with even lower intensity.

[0060] For example, let's take the load indication value as the back EMF pulse value. After determining the back EMF pulse value generated when the impeller continues to run after the fixed-frequency motor is powered off, if the pulse value is greater than or equal to a first threshold (e.g., the first threshold could be 110), it indicates that the garment handling device is in a high water level with a medium-high load state. In this case, the garment handling device is controlled to execute the standard cycle corresponding to the target water level during the washing process. If the pulse value is less than the first threshold but greater than a second threshold (e.g., the second threshold could be 85), it indicates that the garment handling device is in a high water level with a medium-low load state. In this case, the garment handling device is controlled to reduce its operating cycle by one level during the washing process. If the pulse value is less than the second threshold, it indicates that the garment handling device is in a high water level with a low load state. In this case, the garment handling device is controlled to reduce its operating cycle by two levels during the washing process.

[0061] Therefore, by detecting the load applied to the impeller during the operation of the garment processing device and obtaining the load indication value, the operating cycle intensity is adjusted accordingly based on the load indication value to control the garment processing device to execute the operating cycle intensity corresponding to the load indication value during the washing process, so as to avoid the problem of excessive water splashing caused by low load and high water level.

[0062] To achieve the above embodiments, this application also proposes a control device for a garment handling apparatus.

[0063] Figure 3 This is a schematic diagram of the structure of a control device for a garment processing apparatus provided in an embodiment of this application.

[0064] like Figure 3 As shown, the control device 300 of the garment processing device may include: a judgment module 310, a detection module 320 and a control module 330.

[0065] The judgment module 310 is used to determine whether the water level of the clothing processing device is the target water level; the distance between the target water level and the overflow port of the clothing processing device is less than the threshold distance.

[0066] The detection module 320 is used to detect the load applied to the impeller during the operation of the garment processing device when the water level is the target water level, and obtain the load indication value.

[0067] The control module 330 is used to determine that the load indication value is less than a first threshold, reduce the operating cycle intensity, and control the clothes handling device to execute the reduced operating cycle during the washing process.

[0068] As one possible implementation, the detection module 320 may also include: The pulse detection unit is used to determine the back electromotive force pulse value generated when the impeller continues to run after the power is cut off in the fixed-frequency motor that drives the impeller.

[0069] The load determination unit is used to determine the load indication value based on the back electromotive force pulse value.

[0070] As another possible implementation, the detection module 320 may also include: The power determination unit is used to determine the power of the variable frequency motor that drives the impeller to rotate.

[0071] The load determination unit can also be used to determine the load indication value based on the power.

[0072] As another possible implementation, the control module 330 can also be used for: If the load indication value is less than the first threshold and greater than the second threshold, the load will be reduced from the standard cycle corresponding to the target water level to the first cycle; wherein the second threshold is less than the first threshold. If the load indication value is less than or equal to the second threshold, the cycle time will decrease from the standard cycle time corresponding to the target water level to the second cycle time; the intensity of the second cycle time is less than that of the first cycle time.

[0073] As another possible implementation, the control module 330 can also be used for: If the load indication value is determined to be greater than or equal to the first threshold, the clothing handling device is controlled to execute the standard cycle corresponding to the target water level.

[0074] As another possible implementation, the control module 330 can also be used for: If the water level is not the target level, the garment handling device will execute the standard cycle corresponding to the water level during the washing process.

[0075] It should be noted that the foregoing explanation of the control method embodiment for the garment handling device also applies to the control device of the garment handling device in this embodiment, and will not be repeated here.

[0076] The control device of the garment handling apparatus in this application embodiment determines whether the water level of the garment handling apparatus is at the target water level. If the water level is at the target water level, it detects the load applied to the impeller during the operation of the impeller and obtains a load indication value. If the load indication value is determined to be less than a first threshold, the operating cycle intensity is reduced, and the garment handling apparatus is controlled to execute the reduced-intensity operating cycle during the washing process. This method reduces the operating cycle intensity when the garment handling apparatus is at the target water level and the load indication value is less than the first threshold, thus executing a weaker operating cycle during the washing process. This avoids the situation where a high operating cycle intensity during high water level and low load leads to excessive splashing, thereby achieving the goal of reducing splashing.
