Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0047] Clothes processing equipment is an electrical device that mainly processes clothes (shoes) by washing. Drainage is an important part of clothes processing equipment: the washing wastewater in the washing bucket is discharged out of the equipment through the drainage pump. The noise of the drainage pump when working is one of the main noise sources of clothes processing equipment, and it is also a noise source that needs to be focused on in the home environment.

[0048] When the laundry processing device enters the end stage, the washing water in the barrel decreases, causing the drain pump to continue to run for a period of time in a gas-liquid mixed state and generate noise; however, when the laundry processing device enters the end stage, the drain pump may also be blocked and generate noise; the prior art cannot accurately determine whether the drain pump generates noise due to gas-liquid mixing or blocking, and cannot accurately and effectively control the noise. To this end, the embodiments of the present application provide a drainage control method, device, laundry processing device, and storage medium.

[0049] First, an embodiment of the present application provides a clothing processing device, including: a washing tub, a drain pump, a collection device, a water level sensor device and a controller. Among them, the drain pump is configured to discharge the washing water in the washing tub. The collection device is configured to collect the electrical parameters of the drain pump when draining; the electrical parameters include at least one of current, voltage and electric power. For example, the collection device can be at least one of a current sensor, a voltage sensor and an electric power sensor. The water level sensor device is configured to collect the water level value of the washing water in the washing tub. The controller is configured to execute the drainage control method proposed in the embodiment of the present application. The specific implementation of the drainage control method is referred to below.

[0050] In the embodiment, the pressure-conducting pipe connected to the water level sensor is connected to the bottom of the washing tub of the laundry processing device, and the inlet of the drainage pump is located below the bottom of the washing tub, so when the liquid level collected by the water level sensor starts to change, it can be said that the cavity of the drainage pump is full of washing water. Therefore, when the liquid level collected by the water level sensor starts to change, the drainage pump can be controlled to perform low-noise drainage.

[0051] Based on the above introduction, if Figure 1 As shown, the embodiment of the present application proposes a drainage control method, including:

[0052] S100, control the drainage pump to start;

[0053] S200, acquiring electrical parameters of the drainage pump; the electrical parameters include at least one of current, voltage and electric power;

[0054] S500, acquiring a fluctuation value of the electrical parameter according to the electrical parameter;

[0055] S600, after the drainage pump operates with the electrical parameter within a preset range, if the fluctuation value is greater than a preset fluctuation value, obtaining a first water level value in the washing tub;

[0056] S700, if the first water level value is lower than a preset water level value, controlling the drainage pump to be turned off;

[0057] S800: If the first water level value is higher than the preset water level value, an alarm signal is output and the drainage pump is controlled to be turned off.

[0058] In the technical solution of the embodiment of the present application, after the drain pump is started, at least one of the current, voltage and electric power of the drain pump is obtained; and the fluctuation value of the electric parameter is obtained; after the drain pump is operated with the electric parameter within the preset range, if the fluctuation value is greater than the preset fluctuation value, it means that the drainage has entered the end stage, and the first water level value in the detergent bucket is obtained at this time; if the first water level value is lower than the preset water level value, it means that the drain pump has entered the end stage by entering the gas-liquid mixing state, and the drain pump is controlled to be closed at this time, thereby reducing the operation time of the drain pump in the gas-liquid mixing stage, and effectively controlling the noise; and if the first water level value exceeds the preset water level value, it means that the drain pump is blocked at the end stage, and an alarm signal is output at this time to prompt the user to check the drain pump, and the drain pump is controlled to be closed to avoid the drain pump from running in a blocked state, thereby effectively controlling the noise. Therefore, the technical solution provided by the embodiment of the present application can accurately determine whether the noise generated by the drain pump at the end stage is in the gas-liquid mixing state or the blocked state, while effectively controlling the noise at the end stage of the drain pump operation, so that the user can timely understand whether the drain pump is abnormal.

[0059] It should be noted that gas-liquid mixing is a normal phenomenon in the final stage of the drain pump. It is because there is less washing water in the washing tub, which causes air to fill the pump cavity of the drain pump and mix with the washing water. In this stage, the electrical parameters of the drain pump will fluctuate more than when the cavity is full of liquid, and the noise of the drain pump will increase. Therefore, in the embodiment of the present application, when the fluctuation value is greater than the preset fluctuation value, by obtaining the first water level value, if the first water level value is lower than the preset water level value, it means that the drain pump is normal, and it is only because of the gas-liquid mixing that the fluctuation of its electrical parameters increases and noise is generated. If the first water level value is greater than the preset water level value, it means that the drain pump is blocked and cannot effectively drain water, and the noise electrical parameter fluctuation increases, thereby generating noise.

[0060] In addition, it should be noted that when the drain pump is draining normally, since the pump chamber is filled with liquid, the electrical parameters will stabilize within a range when the drain pump is draining in the stable stage; when the drain pump enters the end stage, the fluctuation of the electrical parameters increases. Therefore, after the drain pump operates with the electrical parameters within the preset range, if the fluctuation value is greater than the preset fluctuation value, the first water level value in the washing tub is obtained; that is, the first water level value in the washing tub is obtained in the end stage after the stable stage of the drain pump, so as to determine whether the noise is caused by water vapor mixing or stalling in the end stage.

[0061] In the technical solution of the embodiment of the present application, the fluctuation value can be the difference between two adjacent acquisition moments; or it can be the difference between the value at any moment and the average value in the stable stage. For example, during the operation of the drainage pump, the electrical parameters at two adjacent moments are differentiated to represent the fluctuation value; for another example, during the operation of the drainage pump, the average value of the electrical parameters of the drainage pump in the stable stage is obtained, and the difference between the electrical parameters at any moment and the average value is calculated as the fluctuation value. In the embodiment, the difference is calculated in the form of an absolute value.

[0062] Furthermore, in order to improve the accuracy and reliability of monitoring of the drainage pump at each stage, the fluctuation value can be obtained by averaging multiple differences. For example, the fluctuation value can be obtained by averaging the differences between multiple adjacent acquisition moments. For another example, the fluctuation value can be obtained by averaging the differences between the values ​​at multiple arbitrary moments and the average value of the stable stage. In the embodiment, the difference is calculated in the form of an absolute value.

[0063] In the embodiment, the fluctuation preset value and the water level preset value are set values ​​after multiple experiments on the drainage pump. No specific limitation is made here and they are specifically set by technicians in this field according to the model, working parameters, etc. of the drainage pump.

[0064] In some specific implementations, the electrical parameter may be current.

[0065] In some specific implementations, when the laundry processing device needs to drain water, the controller controls the drain pump to start, and after the drain pump receives the drain instruction, the drain pump starts, and the collection device starts to collect the electrical parameters of the drain pump. The controller also performs the steps of the drainage control method.

[0066] As an alternative implementation of the above embodiment, refer to Figure 2 As shown, if the water level value is lower than the preset water level value, the drainage pump is controlled to stop running; the drainage control method also includes:

[0067] S901, during the dehydration operation of the washing tub, obtaining a second water level value in the washing tub;

[0068] S902, if the second water level value starts to increase, re-control the drainage pump to start;

[0069] S903: When the fluctuation value is greater than the preset fluctuation value, control the drainage pump to be turned off.

[0070] In the embodiment, when the drain pump enters the end stage in a gas-liquid mixed state, when the washing tub starts to dehydrate, the detergent water generated is injected into the pump cavity. When the second water level value starts to increase, it means that the water in the pump cavity has been filled. At this time, the drain pump is controlled to restart and continue to drain. Since there is less washing water in the washing and dehydration stage, the drain pump will quickly enter the water vapor mixing stage. Therefore, when the fluctuation value is greater than the fluctuation preset value, the drain pump is controlled to be closed, and the noise is quickly and effectively controlled. This is repeated until the dehydration is completed.

[0071] As an optional implementation of the above embodiment, when the drainage pump operates with the electrical parameter within the preset range, the fluctuation value of the electrical parameter is obtained according to the electrical parameter. That is, in this embodiment, the drainage pump starts to obtain the fluctuation value of the electrical parameter when it enters the stable stage of operation, so as to judge whether the drainage pump has entered the end stage when it is running in the stable stage; and, since the starting electrical parameter is large when the drainage pump is started, it will quickly drop to a stable state, so the fluctuation during the startup stage is also large, so in order to avoid misjudgment, the fluctuation value is obtained when the drainage pump operates with the electrical parameter within the preset range (in the stable stage).

[0072] As an optional implementation of the above embodiment, Figure 3 As shown, before the drainage pump operates with the electrical parameter within the preset range, the drainage control method further includes:

[0073] S301, acquiring starting electrical parameters of the drainage pump when starting according to the electrical parameters of the drainage pump;

[0074] S302, acquiring operating electrical parameters of the drainage pump when the drainage pump is started and running according to the electrical parameters of the drainage pump;

[0075] S303: If the absolute value of the difference between the operating electrical parameter and the starting electrical parameter is lower than a preset difference value, an alarm signal is output and the drainage pump is controlled to be turned off.

[0076] That is, in the embodiment, before the drainage pump runs in the stable stage, by obtaining the starting electrical parameters and the operating electrical parameters during operation, and when the absolute value of the difference between the two is lower than the preset value of the difference, an alarm signal is output and the drainage pump is controlled to be shut down; under normal operating conditions, the drainage pump will quickly drop to a stable range after starting and enter the stable stage; after starting, if its electrical parameters do not drop to a stable range, that is, the difference between the operating electrical parameters and the starting electrical parameters is small, it means that there is a fault in the drainage pump. In order to reduce noise during a fault, an alarm signal is output and the drainage pump is controlled to be shut down.

[0077] That is, in this embodiment, before the drainage pump enters the stable operation stage, it is judged whether the drainage pump has a fault by whether the difference between the starting electrical parameters and the running electrical parameters is lower than the preset electrical parameters; and after the stable operation stage, it is judged whether the drainage pump has a stall by the fluctuation value of the electrical parameters and the water level value.

[0078] As an optional implementation of the above embodiment, when the drainage pump operates with the electrical parameter within a preset range, starting to obtain the fluctuation value of the electrical parameter based on the electrical parameter includes: when the operating electrical parameter of the drainage pump decreases from the starting electrical parameter to within the preset range, starting to obtain the fluctuation value of the electrical parameter based on the electrical parameter.

[0079] That is, in this embodiment, after starting, when the operating electrical parameters of the drainage pump are reduced from the starting electrical parameters to within the preset range, the drainage pump starts to run smoothly. Only at this time do the electrical parameters start to be measured, and the fluctuation values ​​of the electrical parameters are obtained to reduce the amount of operating data processed by the controller, reduce the control program of the controller, and judge whether the drainage pump has entered the end stage when running in the stable stage; and, because the starting electrical parameters are relatively large when the drainage pump is started, they will quickly drop to enter a stable state, and the fluctuations during the startup stage are also relatively large. Therefore, in order to avoid misjudgment, the fluctuation values ​​are not obtained until the drainage pump is running with the electrical parameters within the preset range (in the stable stage).

[0080] As an optional implementation of the above embodiment, Figure 4 As shown, the control method also includes: S400, if the increase of the electrical parameter within the first preset time is greater than the preset increment, and the drainage pump maintains the increased electrical parameter for the second preset time, then output an alarm signal and control the drainage pump to shut down. When the drainage pump is operating normally, after the drainage pump is started, the electrical parameter quickly drops from the value at the start to a stable range, and in the final stage, the electrical parameter begins to fluctuate; and when the electrical parameter increment in the first preset time is greater than the preset increment in any stage, and the increased electrical parameter is maintained for the second preset time, it is inconsistent with the operating state of the drainage pump in the entire drainage cycle, and therefore it is judged that the drainage pump has a fault. Even if the drainage pump enters the water vapor mixing stage, the fluctuation of the electrical parameter is up and down, and there is no situation where the electrical parameter continues to run for a period of time after the increase.

[0081] Therefore, after the drain pump is started, if the increase in the electrical parameter within the first preset time period is greater than the preset increment, and the drain pump maintains the increased electrical parameter for the second preset time period, the drain pump is judged to be abnormal; in order to avoid noise, the drain pump is controlled to shut down and an alarm signal is output.

[0082] For example, during the startup phase, the electrical parameters of a normally operating drainage pump will drop rapidly; however, if during the startup phase, the electrical parameters of the drainage pump increase within a first preset time period and maintain the increased electrical parameters for a second preset time period, this is obviously inconsistent with the normal state of the drainage pump during the startup phase.

[0083] For example, in the stable stage, the electrical parameters of a normally operating drainage pump fluctuate within a small range within a stable range; however, if in the stable stage, the electrical parameters of the drainage pump increase within a first preset time period and maintain the increased electrical parameters for a second preset time period, this is obviously inconsistent with the normal state of the drainage pump in the stable stage.

[0084] For example, in the ending stage, the electrical parameters of the normally operating drainage pump (water vapor mixing stage) fluctuate up and down over a large range; if in the ending stage, the electrical parameters of the drainage pump increase within the first preset time period, and maintain the increased electrical parameters for the second preset time period, that is, the electrical parameters of the drainage pump do not decrease within the second preset time period after increasing, which is obviously inconsistent with the state of the drainage pump in the water vapor mixing stage in the ending stage.

[0085] In the above embodiment, the first preset time and the second preset time are preset times. The increase of the electrical parameter within the first preset time is greater than the preset increment, which is used to indicate that the electrical parameter suddenly increases during the drainage process.

[0086] As an optional implementation of the above embodiment, the drainage control method further includes: in response to a drainage end instruction, controlling the drainage pump to turn off. In an embodiment, after the dehydration is completed, the controller issues a drainage end instruction to control the drainage pump to turn off.

[0087] In the above embodiments, the output alarm can be output to a user terminal that is communicatively connected to the clothing processing device, or it can be output to a display panel of the clothing processing device; the alarm can be presented in at least one of text, indicator light, sound, etc.

[0088] like Figure 5 As shown, the embodiment of the present application further proposes a drainage control device for a clothes processing device, the clothes processing device comprising a drainage pump and a washing tub, the drainage pump being used to discharge the washing water in the washing tub, comprising:

[0089] A control module 10 is configured to control the start of the drainage pump;

[0090] The acquisition module 20 is configured to acquire the electrical parameters of the drain pump; the electrical parameters include at least one of current, voltage and electric power; according to the electrical parameters, acquire the fluctuation value of the electrical parameters; after the drain pump operates with the electrical parameters within a preset range, if the fluctuation value is greater than the fluctuation preset value, acquire the first water level value in the washing tub;

[0091] The control module 10 is further configured to, if the first water level value is lower than a preset water level value, control the drainage pump to be turned off; if the first water level value is higher than the preset water level value, output an alarm signal and control the drainage pump to be turned off.

[0092] Optionally, the acquisition module 20 is also configured to, if the water level value is lower than the preset water level value, control the drain pump to stop running, and then acquire a second water level value in the washing tub during the dehydration operation of the washing tub; and the control module 10 is also configured to: if the second water level value starts to increase compared to the first water level value when the drain pump is turned off, re-control the drain pump to start; when the fluctuation value is greater than the preset fluctuation value, control the drain pump to turn off.

[0093] Optionally, the acquisition module 20 is configured as an optional implementation of the above embodiment, and when the drainage pump operates with the electrical parameter being within a preset range, starts to acquire the fluctuation value of the electrical parameter according to the electrical parameter.

[0094] Optionally, the acquisition module 20 is also configured to acquire the starting electrical parameters of the drainage pump when it is started according to the electrical parameters of the drainage pump before the drainage pump operates with the electrical parameters within a preset range; and to acquire the operating electrical parameters of the drainage pump when it is started after it is run according to the electrical parameters of the drainage pump; and the control module 10 is configured to output an alarm signal and control the drainage pump to shut down if the absolute value of the difference between the operating electrical parameters and the starting electrical parameters is lower than a preset value of the difference.

[0095] Optionally, when the acquisition module 20 executes the step of acquiring the fluctuation value of the electrical parameter based on the electrical parameter when the drainage pump operates with the electrical parameter within the preset interval, the acquisition module 20 executes the step of acquiring the fluctuation value of the electrical parameter based on the electrical parameter when the operating electrical parameter of the drainage pump decreases from the starting electrical parameter to within the preset interval.

[0096] Optionally, the control module 10 is further configured to output an alarm signal and control the drainage pump to shut down if the increase in the electrical parameter within a first preset time period is greater than a preset increment, and the drainage pump maintains the increased electrical parameter for a second preset time period.
