Detailed Description
In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.
As shown in fig. 1, a control method of a washing machine according to an embodiment of the present application includes:
step S102, judging whether the dehydration rotating speed of the washing machine is smaller than a preset rotating speed.
In the dehydration stage, the motor controls the inner tub of the washing machine to operate at a dehydration rotation speed, wherein the dehydration rotation speed includes a gradual rise from a low rotation speed interval to a high rotation speed interval. When the inner barrel runs at the dehydration rotating speed, the value of the dehydration rotating speed is detected in real time, and whether the value of the dehydration rotating speed is smaller than the preset rotating speed is determined.
Optionally, the preset rotational speed ranges from 400rpm to 800rpm.
Alternatively, the preset rotational speed is set to 600rpm.
Step S104, determining that the dehydration rotation speed is less than the preset rotation speed, and judging whether the water level of the water containing barrel of the washing machine is greater than or equal to the preset water level.
In the high rotation speed section, since noise such as shake and crosstalk of the water level sensor exists at this time, an inaccurate water level test of the tub may be caused. Therefore, in order to ensure accuracy of water level detection of the tub, it is determined that the dehydration rotation speed is less than the preset rotation speed, i.e., the dehydration rotation speed belongs to a low rotation speed zone, in the dehydration stage, the water level of the tub is detected, and a relationship between the water level of the tub and the preset water level is determined.
Alternatively, the water level of the tub may be an average water level or a real-time water level.
As one possible implementation, the method for detecting the water level of the tub by the water level sensor is as follows: the water level sensor collects N times of water levels in a preset time, the collected N times of water levels are sequenced according to the sequence from big to small, the collected maximum water level and the collected minimum water level are removed after sequencing, the remaining N-2 water levels are averaged, and the obtained average value is used as the water level of the water holding barrel of the current washing machine. Such as: the water level sensor collects 5 water levels within 1 second, and the collected 5 water levels are sequenced into H1, H2, H3, H4 and H5 according to the sequence from the water level sensor to the water level sensor; the water level of the tub is: (H2+ H3+ H4)/3. The influence of shaking of the water level sensor in the collected data on the judgment result caused by the low-speed rotation of the motor can be avoided through the water level calculation mode.
Alternatively, the preset water level may be selected reasonably or determined experimentally according to the volume of the tub of the washing machine. In one embodiment, the preset water level is a water level value in the tub detected by the water level sensor when a set amount of water (e.g., 700 ml) is added in the tub of the washing machine in a factory state.
Step S106, determining that the water level is greater than or equal to a preset water level, and controlling a drainage pump of the washing machine to work according to the first drainage beat.
The water level is determined to be greater than or equal to the preset water level, which indicates that the water amount in the water containing bucket is large, and in order to ensure that the water containing bucket is completely drained, the drainage pump is adjusted to work at a first drainage beat based on the water level, so that the residual cleaning liquid in the water containing bucket is avoided.
Optionally, the first drain beat means that the drain pump is periodically turned on for a first operation period and then turned off for a first stop period.
For a washing machine, the period of the drain beats is usually measured in seconds, for example, the first drain beat is measured in 20 seconds as one period, the drain pump is turned on for 15 seconds and then turned off for 5 seconds in one period, and the working beat can be recorded as 15:5, in the application, the motor controls the drainage pump to periodically and circularly work according to the first drainage beat; the larger the number of the working beats is, the shorter the working time of the drainage pump in the period is.
In summary, the control method of the washing machine provided in this embodiment determines whether the dehydration rotation speed of the washing machine is less than the preset rotation speed; determining that the dehydration rotation speed is less than a preset rotation speed, and judging whether the water level of the water containing barrel of the washing machine is greater than or equal to a preset water level; and determining that the water level is greater than or equal to a preset water level, and controlling a drainage pump of the washing machine to work according to the first drainage beat. The problem that the drainage pump is frequently opened and closed is effectively solved while the washing efficiency and the drainage efficiency are ensured, the drainage pump can be controlled to work according to the first drainage beat in a normal intermittent mode under the special condition of water level acquisition errors, and the problem of air trapping of the drainage pump is avoided.
Based on the embodiment shown in fig. 1, in order to solve the problem of frequent opening and closing of the drain pump, a concept of minimum drain time and minimum non-operation of the drain pump is introduced, and as shown in fig. 2, there is provided a control method of a washing machine according to another embodiment, which specifically includes:
step S201, judging whether the dehydration rotation speed of the washing machine is less than a preset rotation speed.
The step S201 is the same as the step S102 in the embodiment shown in fig. 1, and will not be repeated here.
If it is determined that the dehydration rotation speed is greater than or equal to the preset rotation speed, step S202 is entered; if it is determined that the dehydration rotation speed is less than the preset rotation speed, the process proceeds to step S203.
Step S202, controlling the drainage pump to work according to the second drainage beat according to the dewatering curve.
When the dehydration rotating speed is greater than or equal to the preset rotating speed, the dehydration rotating speed of the washing machine is in a high rotating speed interval, at the moment, a dehydration curve of the dehydration rotating speed of the washing machine from a low rotating speed interval to a high rotating speed interval is determined, and a second drainage beat corresponding to the node is determined according to the dehydration curve.
Optionally, the second drain beat means that the drain pump is periodically started for 10 seconds and then stopped for 10 seconds, and sequentially circulates until the dehydration is finished, so that the drain pump is started and stopped at a ratio of 10:10 to run intermittently.
Step S203, judging whether the water level of the washing machine is greater than or equal to a preset water level.
If the water level is greater than or equal to the preset water level, the steps S204-S209 are carried out; if it is determined that the water level is less than the preset water level, the process proceeds to step S210.
Step S204, detecting the water level of the water tub of the washing machine every preset time period.
The preset time length is smaller than or equal to the first operation time length. I.e. at least one water level detection is performed during the first operating period. Optionally, the preset time period is 8 seconds.
When the dehydration rotating speed of the washing machine is smaller than the preset rotating speed, determining that the washing machine is in a low rotating speed interval, and detecting the water level of a water holding barrel of the washing machine once every preset time length, wherein the preset time length is the minimum drainage time of a drainage pump; the preset duration can avoid frequent starting of the drainage pump, and the service life of the drainage pump is prolonged.
The water level detection method of the tub is the same as step S104, and will not be described again here.
Step S205, after the drain pump is controlled to be opened for a preset period of time, whether the water level of the water containing barrel is larger than or equal to a preset water level is judged again.
When the water level is judged to be greater than or equal to the preset water level, the water level of the water holding barrel of the current washing machine is indicated to be at a high water level, the drainage pump is controlled to be started, when the starting time length reaches the preset time length, the water level of the water holding barrel is detected again, whether the water level of the water holding barrel is greater than the preset water level is judged, and the drainage pump is still in an opened state when the water level of the water holding barrel is lower.
If the water level is greater than or equal to the preset water level, the step S206 is entered; if the water level is smaller than the preset water level, controlling the drainage pump to be closed for a first stopping time period and then to be opened again.
In step S206, the drain pump is controlled to continue to be turned on for a second operation duration.
The second operation time length is equal to the difference time length between the first operation time length and the preset time length, and the second operation time length is smaller than or equal to the preset time length.
When the water level of the water containing bucket is still larger than or equal to the preset water level, the water containing bucket water level is still at the high water level after the drainage pump is started for the preset time period, and therefore the drainage pump is continuously controlled to be started for the second operation time period.
Optionally, when the difference time between the first operation time length and the preset time length is longer than the preset time length, the second operation time length is the preset time length, and step S205 is continuously performed.
In step S207, the drain pump is controlled to be turned off for a third stop period.
When the drain pump continues to be started for the second operation duration, the drain pump is indicated to be continuously started for the first operation duration, and according to the first drain beat, the drain pump needs to be controlled to be closed for the first stop duration after the drain pump is started for the first operation duration.
As a possible implementation manner, when the sum time of the second operation time length and the first stop time length is longer than the preset time length, after the second operation time length is operated, the drain pump can only be controlled to close the third stop time length, wherein the sum time length of the second operation time length and the third stop time length is equal to the preset time length. After the drain pump is turned off for a third stop period, the water level of the tub is again detected.
As another possible implementation manner, when the sum duration of the second operation duration and the first stop duration is smaller than the preset duration, after the second operation duration is operated, the drain pump is controlled to be turned off and turned on again after the first stop duration is closed.
Optionally, the first operation duration is 15 seconds, the first stop duration is 5 seconds, the preset duration is 8 seconds, the second operation duration is 7 seconds, and the third stop duration is 1 second.
Step S208, it is re-determined whether the water level of the tub is greater than or equal to a preset water level.
If the water level is greater than or equal to the preset water level, the step S205 is performed; if it is determined that the water level is less than the preset water level, the process proceeds to step S209.
In step S209, the drain pump is controlled to continuously close the difference time between the first stop time and the third stop time.
The first stopping time period is smaller than a preset time period.
And when the water level of the water containing bucket is smaller than the preset water level, continuously controlling the drainage pump to be closed.
When the sum time of the second operation time length and the first stop time length is longer than the preset time length, controlling the drainage pump to be continuously closed, restarting the drainage pump after the difference time length of the first stop time length and the third stop time length is longer than the preset time length, and judging whether the water level of the water holding barrel is greater than or equal to the preset water level again when the next detection preset time length is reached.
Step S210, the drain pump is controlled to be turned off for a second stop period, and step S203 is re-executed.
When the water level of the water containing bucket is judged to be smaller than the preset water level, the water level of the water containing bucket is indicated to be at a low water level, and the drainage pump is controlled to be closed for a second stopping time period. Wherein the second stop duration is a duration during which the drain pump is not operated at minimum.
In summary, the present embodiment provides a control method of a washing machine, by detecting a water level of a tub of the washing machine every preset time period when it is determined that the water level is greater than or equal to a preset water level, and controlling a drain pump to operate according to a first drain beat; and when the water level is determined to be less than the preset water level, controlling the drainage pump to close the second stopping time period, and re-detecting the water level of the water containing barrel after the second stopping time period. The problem that the drainage pump is frequently opened and closed is effectively solved, the drainage pump can be controlled to work according to the first drainage beat in a normal intermittent mode under the special condition of water level acquisition errors, and the problem of air trapping of the drainage pump is avoided.
As a specific example, as shown in fig. 3, the control method of the washing machine according to the embodiment of the present application includes the following steps:
step S301, judging whether the dehydration rotation speed of the washing machine is less than 600rpm.
If it is less than 600rpm, the process proceeds to step 303, and if it is more than 600rpm, the process proceeds to step S302.
Step S302, controlling the drainage pump to work according to the second drainage beat according to the dewatering curve.
Step S303, judging whether the water level of the water tub of the washing machine is greater than or equal to a preset water level.
If the water level is greater than or equal to the preset water level, the steps S304-S309 are performed; if the water level is smaller than the preset water level, the process proceeds to step S310.
Step S304, setting the minimum opening time of the drain pump to 8 seconds, and re-detecting the water level every 8 seconds.
In step S305, after the drain pump is controlled to be turned on for 8 seconds, the water level is re-detected to be greater than the preset water level.
Step S306, after continuously controlling the drain pump to be started for 7 seconds, closing the drain pump for 1 second; the re-detection water level is greater than the preset water level.
Step S307, after the drain pump is continuously controlled to be turned off for 4 seconds, the drain pump is turned on for 4 seconds, and then the water level is re-detected to be larger than the preset water level.
Step S308, after the drain pump is continuously controlled to be started for 8 seconds, the water level is re-detected to be larger than the preset water level.
Step S309, after continuing to control the drain pump to turn on for 3 seconds, turning off the drain pump for 5 seconds, and re-executing step S303.
