The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
In the related art, the operation state of the water pump of the laundry treating apparatus is detected based on the water level detection to determine whether the water pump has a fault. However, the water level detection has certain errors, which results in inaccurate detection, for example, during the washing process, the water level fluctuates, so that the accurate water level cannot be measured, and thus the operation state of the water pump cannot be accurately judged.
In order to solve the problems of the related art, the application provides a water pump operation control method, which is used for pumping water by controlling the operation of a water pump of a clothes treatment device; monitoring the current of the water pump; and detecting to determine the fault severity of the water pump according to the current. Therefore, the fault severity of the water pump is determined according to the current in the operation process of the water pump, the working state of the water pump can be accurately obtained, and the service life of the water pump is prolonged.
The water pump operation control method, apparatus, laundry treatment apparatus, and medium according to the embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a water pump operation control method according to an embodiment of the present application.
As shown in fig. 1, the water pump operation control method includes the steps of:
The water pump is used for sending water which can be recycled for the second time into the clothes treatment device to wash clothes, and the purposes of recycling the water and saving the water are achieved. The water pump may be disposed inside the laundry treating apparatus, or may be disposed outside the laundry treating apparatus, which is not limited herein.
In the embodiment of the application, when the water pump of the clothes treatment device is controlled to operate, the water pump can extend into the circulating pool through the water suction pipe, the circulating pool can be a bathtub storing bath water, the bath water is circularly used for washing clothes, and the purposes of water resource recycling and water saving can be achieved.
In a mountain area or the like where there is no tap water, there is a possibility that the water pump of the laundry treating apparatus is controlled to operate, and the water pump may extend into the water storage tub or the water storage tank through the suction pipe to suck water in the water storage tub or the water storage tank into the washing tub, thereby performing a laundry washing function. Therefore, the application range of the clothes treatment device is enlarged, and the clothes treatment device can be used for washing clothes in regions without tap water.
It should be noted that, before controlling the water pump of the laundry treatment apparatus to operate to pump water, the water inlet valve of the laundry treatment apparatus needs to be controlled to open, the water is supplied to the washing tub to the set reset water level, and then the water inlet valve of the laundry treatment apparatus is controlled to close, so that the phenomenon that the washing tub of the laundry treatment apparatus idles and the laundry treatment apparatus is easily damaged is avoided.
In the embodiment of the application, the current in the operation process of the water pump is monitored in real time by setting the current detection module of the clothes treatment device in the operation process of the water pump for controlling the clothes treatment device.
Specifically, in the running process of the water pump, a current detection module is used for acquiring a working flow signal of the water pump in real time and transmitting the working flow signal of the water pump to a controller of the clothes treatment device, so that the controller calculates the current of the water pump according to the received working flow signal of the water pump.
And 103, detecting to determine the fault severity of the water pump according to the current.
In the embodiment of the application, after the current when the water pump of the clothes treatment device operates is monitored, the fault severity of the water pump can be determined according to the current.
In a possible case, after the current when the water pump operates is detected, the current is determined to be greater than the first current threshold and less than the second current threshold, and the severity of the fault is determined to be mild. Wherein the first current threshold is less than the second current threshold.
It can be understood that, during the process of pumping water by the water pump of the clothes treatment device, some flocks may be sucked into the water suction pipe, so that the resistance of the wind impeller of the water pump becomes large, and the current of the water pump during operation changes. In this case, the current when the water pump operates may be larger than the current when the water pump operates in a normal state, and it may be determined that the severity of the failure of the water pump is mild.
In another possible case, after the current when the water pump operates is detected, the current is determined to be larger than the second current threshold value, and then the severity of the fault is determined to be severe.
It can be understood that, during the process of pumping water by the water pump of the clothes treatment device, a large amount of flocks are sucked into the water suction pipe, so that the impeller of the water pump is locked, and the current of the water pump during operation is larger than the second current threshold. In this case, it can be determined that the severity of the failure of the water pump is severe.
In this application embodiment, confirm the trouble severity of water pump for the severe back, in order to avoid the water pump to continue the operation, cause the damage, under this kind of condition, control clothing processing apparatus stop operation to send the suggestion, make the user in time solve the trouble of water pump, in order to guarantee the normal operating of water pump, thereby be favorable to prolonging the life of water pump.
It should be noted that the sound may be generated by, for example, controlling the buzzer to sound for a long time; the prompting information, for example, the alarm code, etc., may also be displayed on the display interface of the laundry processing apparatus to remind the user that the water pump is out of order, and the specific prompting manner is not limited herein.
According to the water pump operation control method, water is pumped by controlling the operation of the water pump of the clothes treatment device; monitoring the current of the water pump; and detecting to determine the fault severity of the water pump according to the current. Therefore, the fault severity of the water pump is determined according to the current in the operation process of the water pump, the working state of the water pump can be accurately obtained, and the service life of the water pump is prolonged.
In another possible case, after monitoring the current of the water pump in step 102, it is determined that the current is less than the first current threshold, in which case the water level in the tub of the laundry treatment apparatus is monitored to determine the water flow rate of the water pumped by the water pump according to the water level variation to determine whether the water pump is operating normally. The above process is described in detail with reference to fig. 2, and fig. 2 is a schematic flow chart of another water pump operation control method according to an embodiment of the present disclosure.
As shown in fig. 2, the method for controlling the operation of the water pump may further include the steps of:
in step 201, a water pump of the laundry treating apparatus is controlled to operate to pump water.
In step 202, the current of the water pump is monitored.
In the embodiment of the present application, the implementation processes of step 201 and step 202 may refer to the implementation processes of step 101 and step 102 in the foregoing embodiment, and are not described herein again.
And step 203, if the current is smaller than the first current threshold, determining the water flow of the water pump for pumping water according to the water level change in the set time interval of the clothes treatment device.
In the embodiment of the application, when the current when monitoring the water pump operation is less than the first current threshold, the normal operation of the water pump cannot be completely determined. In this application, through monitoring water level change in the washing tub of clothing processing apparatus when the water pump draws water to confirm whether the discharge that the water pump drew water is normal according to water level change, confirm whether the water pump normally operates.
As a possible implementation manner, when it is determined that the current of the water pump is less than the first current threshold, the water level in the washing tub may be detected once every set time interval by a water level sensor provided in the laundry treatment apparatus, so as to determine the water flow rate at which the water pump pumps water according to the water level variation in the set time interval. The set time interval may be set by a built-in program of the laundry treatment apparatus, or may be preset by a user, which is not limited herein. For example, the set time interval is 20 seconds.
It can be understood that the detection of a large change in water level within a time interval in the washing tub by the water level sensor indicates a large water flow rate for the water pump to pump water. On the contrary, the water level change is smaller, which indicates that the water flow rate for pumping water by the water pump is smaller.
The flow threshold is the minimum value of the water flow when the water pump normally operates, which is preset.
In the embodiment of the application, after the water flow rate of pumping water by the water pump is determined according to the water level change of the washing barrel of the clothes treatment device, the water flow rate can be compared with the flow threshold value so as to determine the fault severity of the water pump.
In one possible case, the water flow rate of the water pumped by the water pump is determined to be greater than or equal to the flow threshold value according to the water level change of the washing barrel in the set time interval of the clothes treatment device, and the water pump is indicated to be in normal operation.
And step 206, determining that the water flow is smaller than the flow threshold, and determining that the severity of the fault is mild.
In another possible case, the water flow rate of the water pumped by the water pump is determined to be less than the flow threshold value according to the water level change of the washing tub within the set time interval of the clothes treatment device, possibly due to the water in the water storage tank being pumped out by the water pump, or possibly due to the presence of foam in the water. In this case, it can be determined that the severity of the malfunction of the water pump is mild.
According to the water pump operation control method, the current of the water pump is monitored, the current is determined to be smaller than the first current threshold, and the water flow rate of pumping water by the water pump is determined according to the water level change in the set time interval of the clothes treatment device; determining that the water flow is greater than or equal to a flow threshold value, and determining that the water pump normally operates; and if the water flow is determined to be smaller than the flow threshold, determining that the fault severity is mild. Therefore, the fault severity of the water pump is determined by monitoring the current of the water pump and the water level change of the clothes treatment device, and the detection accuracy of the running state of the water pump is ensured.
On the basis of the embodiment, after the severity of the water pump fault is determined to be slight, the water pump can be turned off, the water inlet valve of the clothes treatment device is controlled to be opened to feed water, when the water inlet reaches the set duration, the water inlet valve is turned off, the water pump is controlled to run again, and whether the water pump fault is relieved or not is determined according to a circuit after the water pump runs again, so that the running state of the water pump is further controlled. The above process is described in detail with reference to fig. 3, and fig. 3 is a schematic flow chart of another water pump operation control method according to an embodiment of the present disclosure.
As shown in fig. 3, the method for controlling the operation of the water pump may further include the steps of:
In the embodiment of the application, after the severity of the fault of the water pump is determined to be mild, the water pump is controlled to be closed, and the water inlet valve of the clothes treatment device is controlled to be opened, so that water enters the washing barrel through the water inlet valve.
It can be understood that the serious degree of the water pump failure is mild, which may be caused by the water inlet pipeline of the water pump being blocked by swarf, foam and the like. Under the condition, the water pump is controlled to be closed, the water inlet valve of the clothes treatment device is opened, and the water inlet pipeline is flushed by water entering through the water inlet valve, so that the problem that the water inlet pipeline is blocked by flock, foam and the like is solved.
And step 302, when the water inlet reaches the set time, closing the water inlet valve and controlling the water pump to operate again.
In the embodiment of the application, the water inlet valve of the clothes treatment device is controlled to be opened, and after the water is fed into the washing barrel for a set time, the water inlet valve is controlled to be closed, and the water pump is controlled to operate again.
And 303, determining that the water pump normally operates according to the current monitored after the water pump operates again, and controlling the water pump to continue operating to pump water to a target water level.
The target water level may be preset by a built-in program of the laundry treatment apparatus, or may be manually set by a user according to laundry to be washed placed in the laundry treatment apparatus, which is not limited herein.
In the embodiment of the application, after the water pump operates again, the current of the water pump during operation is continuously monitored, the current is determined to be smaller than the first current threshold, the water flow rate of pumping water by the water pump is determined to be larger than or equal to the flow threshold according to the water level change in the set time interval of the clothes treatment device, and then the water pump is determined to operate normally. In this case, it is explained that the water inlet valve of the laundry treating apparatus is filled with water to solve the problem of the light malfunction of the water pump, and the water pump is controlled to continue to operate to pump water to the target water level.
And step 304, according to the current monitored after the water pump operates again, if the fault is determined not to be relieved, controlling the water pump to stop operating, and opening the water inlet valve again to enable water to enter the water level to reach the target water level.
In a possible situation, after the water pump operates again, the current of the water pump during operation is continuously monitored, the current is determined to be still larger than the first current threshold value, the fault of the water pump is not relieved, and the water pump still has a light fault.
In another possible case, after the water pump operates again, the current of the water pump during operation is continuously monitored, the current is determined to be smaller than the first current threshold, but the water flow rate of the water pumped by the water pump is determined to be smaller than the flow threshold according to the water level change in the set time interval of the clothes treatment device, so that the fault of the water pump is not removed, and the water pump still has a light fault.
In the embodiment of the application, when the fault is determined not to be relieved according to the current monitored after the water pump operates again, the water pump is controlled to stop operating, and the water inlet valve of the clothes treatment device is controlled again to be opened so as to supply water to the washing tub to reach the target water level.
It should be noted that, the steps 303 and 304 are not performed sequentially, and in actual use, only the step 303 or only the step 304 is performed, which is not limited herein.
In the embodiment of the application, when the fault is determined not to be relieved according to the current monitored after the water pump operates again, the clothes processing device can be controlled to send a prompt to remind a user that the water pump has the fault. For example, the user may be alerted by flashing a light.
According to the water pump operation control method, the water pump is closed, and the water inlet valve of the clothes treatment device is opened to feed water; when the water inlet reaches the set time, closing the water inlet valve and controlling the water pump to operate again; according to the current monitored after the water pump operates again, the water pump is determined to operate normally, and the water pump is controlled to operate continuously to pump water to a target water level; and if the fault is not relieved according to the current monitored after the water pump operates again, controlling the water pump to stop operating, and opening the water inlet valve again to enable water to enter the target water level. Therefore, when the fault degree of the water pump is slight, the water inlet pipeline is flushed by opening the water inlet valve to feed water, whether the fault is relieved or not is judged according to the current monitored after the water pump operates again, and the water inlet efficiency of the water pump is improved.
