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 process of using the clothes treatment device to wash clothes, taking a pulsator washing machine without an outer barrel or a half outer barrel as an example, when high water level occurs in the washing process, water flows out of an overflow port due to the stirring action of a pulsator, and the actual water level in a washing barrel is obviously lower than the theoretical water level. At this time, in order to ensure that the water level is within a reasonable range, water needs to be replenished in the whole washing process, so that the water replenishing is too frequent, and the use experience of a user is affected.
In order to solve the technical problems, the application provides a water inlet control method of a clothes treatment device, which judges whether the water injection level of the clothes treatment device is a target water level; the distance between the target water level and the overflow port of the clothes treatment device is smaller than the threshold distance; controlling a motor of the clothes treatment device to drive a wave wheel to rotate so as to execute a washing process when the water injection level is a target level; detecting the load applied to the impeller during the operation of the impeller to obtain a load indicated value; the load indicated value is smaller than the load threshold value, and the water inlet valve of the clothes treatment device is forbidden to supplement water in the washing process; and the load indicated value is greater than or equal to the load threshold value, and the water inlet valve is controlled to supplement water according to the water level change in the washing process. Therefore, in the washing process, the water inlet valve of the clothes treatment device is controlled according to the load indication value to determine whether to execute the water replenishing operation or not, so that the problem of frequent water replenishing is avoided, and the water level height in the washing barrel in the whole washing process is kept in a reasonable range.
Hereinafter, a water inlet control method and apparatus of a laundry treating apparatus according to an embodiment of the present application will be described with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a water inlet control method of a clothes treatment apparatus according to an embodiment of the present application.
As shown in fig. 1, the water inlet control method includes the steps of:
step 101, judging whether the water filling level of the clothes treatment device is a target water level.
Wherein, the distance between the target water level and the overflow port of the clothes treatment device is less than the threshold distance.
As an example, the laundry treatment apparatus of the embodiment of the present application may be a pulsator washing machine without an outer tub, a half outer tub pulsator washing machine, and the like.
In the embodiment of the application, before washing clothes, after detecting that the clothes to be washed are placed in a washing barrel of the clothes treatment device, the water inlet valve of the clothes treatment device is controlled to be opened so as to fill water into the clothes treatment device, and after the water filling is finished, whether the water filling level of the clothes treatment device is a target water level is judged.
In the embodiment of the present application, the target water level may be understood as a highest water level, and when the laundry treating apparatus performs a washing process in a high water level state, water in the washing tub may overflow from the overflow port. In a possible case, the target level of the water entering the laundry treatment apparatus is spaced from the overflow of the laundry treatment apparatus by less than a threshold distance, for example, 4 cm. In the embodiment of the application, the clothes treatment device can automatically control the water inlet valve to be opened to fill water into the clothes treatment device after detecting that the clothes to be washed are put into the washing barrel by a user. The laundry treating apparatus may control the water inlet valve to be opened to fill the laundry treating apparatus in response to a user operation after detecting a water filling level selected by a user.
And 102, controlling a motor of the clothes treatment device to drive a wave wheel to rotate so as to execute a washing process when the water filling level is a target water level.
In the embodiment of the application, after the water injection of the clothes treatment device, the water injection level in the washing barrel of the clothes treatment device is judged to be the target water level, the motor of the clothes treatment device is controlled to drive the impeller to operate, under the driving of the impeller, the water flow in the washing barrel forms the frequent left-hand rotation and the frequent right-hand rotation vortex, and the clothes in the washing barrel are driven to rotate and roll along with the water flow so as to execute the washing process.
And 103, detecting the load applied to the impeller during the operation of the impeller to obtain a load indicated value.
In the embodiment of the application, in the washing process of the clothes treatment device, the load applied to the impeller in the operation of the impeller is detected to obtain the load indication value, namely, the weight of the wet clothes after water inflow is finished is determined by detecting the load applied to the impeller in the operation of the impeller. For example, the weight of the wet clothes may be measured from the pulse or power of the pulsator driving motor.
The load amount indication values correspond to different loads. For example, it may be a high load, a low load. As an example, the weight of the laundry to be washed corresponding to a high load may be 8-12 kg, and the weight of the laundry to be washed corresponding to a low load may be 1-6 kg. Each load of the laundry treating apparatus has a corresponding inlet water level and washing beat to implement washing of the corresponding load. In general, a high load corresponds to a high feed water level and a high intensity washing cycle, and a low load corresponds to a low feed water level and a low intensity washing cycle.
As a possible implementation manner, the load amount indicating value may be a back electromotive force pulse value generated when the wave wheel continues to operate after the fixed-frequency motor is powered off. In this case, the loading indicated value can be determined according to the back electromotive force pulse value by detecting the back electromotive force pulse value generated when the wave wheel continues to operate after the fixed frequency motor driving the wave wheel to operate is powered off. For example, the constant frequency motor is driven to rotate and stop, a set of back electromotive force pulse values are generated after the constant frequency motor is powered off and stops rotating, and the load indication value can be determined by reading the back electromotive force pulse values through the clothes treatment device.
As another possible implementation mode, the loading indicated value applied to the impeller during the operation of the impeller can be the power for driving the impeller to operate by the variable frequency motor. In this case, the power of the variable frequency motor driving the pulsator to operate when driving the pulsator to operate can be detected, so as to determine the load indicated value according to the power of the variable frequency motor driving the pulsator to operate.
For example, when the wet weight is determined according to the power of the inverter motor driving the pulsator to operate during the washing process, the information such as the first total power of the inverter motor driving the pulsator to operate during the washing process in the rotation speed increasing stage, the second total power of the inverter motor driving the pulsator to operate during the stable washing stage, and the rotating average torque fluctuation value of the pulsator during the stable washing stage can be obtained. When the variable frequency motor reaches a first rotating speed, the power of the variable frequency motor is accumulated when the impeller rotates for one circle, when the impeller rotates for m circles in the washing stage, the impeller rotates for m circles together, and the total power of the variable frequency motor rotating for m circles by the impeller is accumulated to be a first total power. And in the washing process, the total power of the variable frequency motor driving the impeller to rotate for the second number of turns when the variable frequency motor stably rotates at the second rotating speed is the second total power. And in the stable washing stage, the rotation fluctuation value of the variable frequency motor of each circle of rotation of the washing barrel is obtained, the total number of circles of rotation of the washing barrel is obtained, and the average torque fluctuation value can be obtained through calculation.
Further, the weight of the wet clothes in the washing tub is calculated according to the following formula:
f(G)=K1*(P1/m+K2*P2/n)+K3*P1*P2/T0
wherein f (G) is the weight of the wet clothes after water is fed into the washing barrel; p1 is the first total power; p2 is the second total power; m is the first number of turns; n is a second number of turns; t0 is the average torque ripple value; k1, K2, K3 are inertia constants.
In the embodiment of the application, the load applied to the impeller in the operation of the impeller is detected, and after the load indicated value is obtained, whether the load indicated value is smaller than the load threshold value is judged.
In the following, the load amount indication value determined according to the back electromotive force pulse value is taken as an example, and in this case, the load amount threshold value may be a pulse value, for example, 85.
In the embodiment of the application, a counter electromotive force pulse value generated when the wave wheel continues to operate after the fixed frequency motor is powered off is determined for the fixed frequency motor driving the wave wheel to operate, and the relationship between the load indicated value and the load threshold value is judged after the load indicated value is determined according to the counter electromotive force pulse value.
And 104, prohibiting the water inlet valve of the clothes treatment device from supplementing water in the washing process when the load indicated value is smaller than the load threshold value.
As a possible case, when the load amount indication value is smaller than the load amount threshold, at this time, the load in the washing tub of the laundry treating apparatus is small and may be a low load, and the current water level in the washing tub is high and does not match the load amount. However, when the impeller drives the water flow to rotate, water flows out from the overflow port, when the water level is reduced to the water level height matched with the clothes, no water basically overflows from the overflow port, the washing process is continuously executed, and the water inlet valve of the clothes treatment device is not required to be controlled for supplementing water in the whole clothes washing process.
For example, if the load threshold is 85, the indicated value of the load is 50 according to the back electromotive force pulse value, in this case, the washing tub of the laundry treatment apparatus is under low load, and when the water level in the washing tub is higher, the pulsator rotates to drive the water flow, so that water flows out from the overflow port, and when the water level drops to a water level matched with the laundry, the washing process is continuously performed, and the water inlet valve of the laundry treatment apparatus does not need to be controlled to supplement the water during the process of washing the laundry.
In the embodiment of the application, when the load in the washing barrel of the clothes treatment device is determined to be small and the load is low, the clothes can be washed by selecting a weaker washing rhythm, so that the water in the washing barrel is prevented from splashing from the overflow port in the washing process.
And 105, controlling the water inlet valve to supplement water according to the water level change in the washing process, wherein the load indicated value is larger than or equal to the load threshold value.
As a possible case, when the load amount indication value is greater than or equal to the load amount threshold value, at this time, the load in the washing tub of the laundry treating apparatus is not a small load case, and may be a high load, for example. Under the condition, the water level in the washing barrel is reduced due to the fact that the clothes absorb more water, in the washing process, the water inlet valve needs to be controlled to be opened according to the water level change in the washing barrel to supplement water, and the water inlet valve is controlled to be closed to stop supplementing water until the water level in the washing barrel reaches the standard water level matched with the load threshold value.
It should be noted that the distance between the standard water level matched with the load threshold and the overflow port is greater than or equal to the threshold distance, wherein the threshold distance is in the range of 2 cm to 10 cm.
In the embodiment of the application, when the load in the washing barrel of the clothes processing device is determined to be large and the load is high, the clothes can be washed by selecting a strong beat, and the condition that the clothes are not washed completely when the clothes are more is avoided.
It should be noted that, the steps 104 and 105 are not sequentially executed, but only the step 104 or only the step 105 is determined according to the load indication value.
The water inlet control method of the clothes treatment device provided by the embodiment of the application judges whether the water filling level of the clothes treatment device is a target water level; the distance between the target water level and the overflow port of the clothes treatment device is smaller than the threshold distance; controlling a motor of the clothes treatment device to drive a wave wheel to rotate so as to execute a washing process when the water injection level is a target level; detecting the load applied to the impeller during the operation of the impeller to obtain a load indicated value; the load indicated value is smaller than the load threshold value, and the water inlet valve of the clothes treatment device is forbidden to supplement water in the washing process; and the load indicated value is greater than or equal to the load threshold value, and the water inlet valve is controlled to supplement water according to the water level change in the washing process. Therefore, in the washing process, the water inlet valve of the clothes treatment device is controlled according to the load indication value to determine whether to execute the water replenishing operation or not, so that the problem of frequent water replenishing is avoided, and the water level height in the washing barrel in the whole washing process is kept in a reasonable range.
In a possible case, in the step 105, the load indicated value is greater than or equal to the load threshold, and in the washing process, when the water inlet valve is controlled to replenish the water according to the water level change, the water level indicated value monitored by the water level sensor may be periodically obtained, so that when the difference between the water level indicated values before and after a single period is determined to be greater than the water level threshold according to the periodically obtained water level indicated value, the water inlet valve is controlled to be opened to replenish the water, thereby avoiding the situation that the replenishing water operation is too frequent. The above process is described in detail with reference to fig. 2, and fig. 2 is a schematic flow chart of another water inlet control method of a laundry treatment apparatus according to an embodiment of the present application.
As shown in fig. 2, the water inlet control method may include the steps of:
step 201, periodically obtaining a water level indicated value monitored by the water level sensor.
As a possible case, the water level sensor may be a frequency type water level sensor, and the water level indicating value is an oscillation frequency value output by the water level sensor.
In the embodiment of the application, in the process of washing clothes by the clothes treatment device, the oscillation frequency value output by the frequency type water level sensor can be periodically obtained, so that the height of the water level in the washing tub can be determined according to the oscillation frequency value.
As an example, the single period for acquiring the water level sensor may range from 110 seconds to 130 seconds. For example, the water level indicating value monitored by the water level sensor may be acquired every 120 seconds.
Step 202, according to the water level indicating values obtained periodically, determining that the difference value of the water level indicating values before and after a single period is larger than a water level threshold value, and controlling a water inlet valve to be opened to supplement water.
The water level threshold is a set threshold, for example, when the water level indicating value is an oscillation frequency value output by the water level sensor, the water level threshold may be 100 HZ.
Under a possible condition, after the oscillation frequency values monitored by the frequency type water level sensor are periodically obtained, when the difference value of the oscillation frequency values before and after a single period is determined to be larger than the water level threshold value, the water inlet valve is controlled to be opened at the moment, and water replenishing operation is executed to replenish water to the washing barrel. And in the process of controlling the water inlet valve to open for supplementing water, periodically acquiring oscillation frequency values obtained by monitoring of the frequency type water level sensor, and controlling the water inlet valve to close to stop supplementing water inlet operation when the difference value of the oscillation frequency values before and after a single period is less than or equal to the water level difference value.
In another possible case, after the water level indicated value obtained by monitoring of the frequency type water level sensor is periodically obtained, when the difference value of oscillation frequency values before and after a single period is determined to be less than or equal to the water level threshold value, the washing process is continuously executed, and the water replenishing operation is not executed.
According to the water inlet control method of the clothes treatment device, the water level indicated value obtained by monitoring the water level sensor is obtained periodically, the difference value of the water level indicated value before and after a single period is determined to be larger than the water level threshold value according to the water level indicated value obtained periodically, and the water inlet valve is controlled to be opened to supplement water. Therefore, whether the water inlet valve needs to be controlled to be opened to supply water or not through periodic judgment is avoided, and the phenomenon that water is excessively frequently supplied is avoided, so that the use experience of a user is improved.
In order to realize the above embodiments, the present application further provides a water inlet control device of a clothes treatment device.
