Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, the described embodiments should not be construed as limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In the related art, in order to effectively improve noise generated when the drain pump operates, the drain pump is controlled to operate according to a water level detection value of a water level (for example, the water level in a washing tub of a washing machine or the water level in a water containing box of a clothes dryer) collected in the clothes treatment equipment. For example, because the reason of last drainage structures, lead to the water in the drain pump body can not discharge completely, the drain pump is in half steam state (being that the pump body of drain pump is not full of water) most of the time in the later stage of dehydration, and the impeller is high-speed rotatory when half steam state and is patted the surface of water and will produce great noise. Based on this, according to the action of the water level detection value of the water level, when the water level in the clothes treatment equipment reaches or exceeds the set water level threshold value, the water level in the clothes treatment equipment is controlled to be started for a set time, so that the water level in the clothes treatment equipment can meet the set water level threshold value requirement when the water level in the clothes treatment equipment is started, the operation of the water level in a semi-water vapor state is effectively avoided, and the noise reduction is facilitated. If the water level sensor breaks down, the water level detection value is falsely reported, for example, the water level is still falsely judged to reach the requirement when the water level in the clothes treatment equipment does not meet the requirement, the drainage pump possibly works for a long time, the drainage pump idles to generate larger noise, and the heating of continuous work influences the service life of the drainage pump.
Based on this, in various embodiments of the present invention, if the continuous operation duration corresponding to the drain pump reaches or exceeds the set value, the drain pump is controlled to operate in the second mode, and in the second mode, the drain pump operates cyclically at the first on-off ratio, so that the continuous operation duration of the drain pump due to the water level detection fault can be effectively reduced, thereby reducing the operation noise of the drain pump, avoiding the damage of heating and the like of the drain pump due to the overlong continuous operation duration, and being beneficial to prolonging the service life of the drain pump.
An embodiment of the present invention provides a drainage control method for a clothes treatment apparatus, as shown in fig. 1, the method including:
In the embodiment of the present invention, the laundry treating apparatus may be a washing machine, a dryer, or a washing and drying all-in-one machine. For the dryer, the control means controls a drain pump of the dryer to operate in a first mode when the dryer operates. For the washing machine, when the washing machine enters the dehydration process, the control device controls the drain pump of the washing machine to operate in the first mode. For the washing and drying integrated machine, when the washing machine enters a drying program or a dewatering program, the control device controls the drainage pump of the washing machine to work in a first mode.
In one embodiment, the controlling the drain pump of the laundry treating apparatus to operate in a first mode includes:
periodically acquiring first water level detection values corresponding to the water levels, wherein the first water level detection values of two adjacent times take a first duration as an interval;
if the first water level detection value reaches or exceeds a set water level threshold value, controlling the drainage pump to operate for a set time;
if the corresponding water level detection value reaches or exceeds the set water level threshold value when the set time length is finished, returning to the step of controlling the drainage pump to operate for the set time length;
and if the corresponding water level detection value is lower than the set water level threshold value when the set time length is finished, returning to the step of periodically acquiring the first water level detection value corresponding to the water level.
In this way, when the first water level detection value reaches or exceeds the set water level threshold, the drainage pump is controlled to continuously operate for the set time period until the water level detection value is lower than the set water level threshold, and then whether the first water level detection value exceeds or reaches the set water level threshold is periodically judged.
Here, the set water level threshold may be reasonably selected or experimentally determined according to the volume of the water container of the laundry treatment apparatus. Taking a washing machine as an example, the set water level threshold is a water level value in a washing tub detected by a water level sensor when a set amount of water (e.g. 700ml) is added into the washing tub of the washing machine in a factory state.
The drainage pump is usually influenced by voltage fluctuation, namely, the starting speed of the drainage pump is influenced under different voltage working conditions. Based on this, in one embodiment, the set time period is 8 seconds or more. In this way, it is ensured that the drain pump can operate efficiently and drain a certain amount of water.
In an application example, in the first mode, the first duration is 3 seconds, the set duration is 8 seconds, that is, a first water level detection value detected by the water level sensor is obtained every 3 seconds, if the first water level detection value reaches or exceeds the set water level threshold, the drain pump operates for 8 seconds, and if the corresponding water level detection value at the end of the 8 seconds of operation is still higher than the set water level threshold, the operation of the next set duration (for example, 8 seconds) is continued until the corresponding water level detection value at the end of the current set duration is lower than the set water level threshold, the first water level detection value is obtained every 3 seconds again, and whether the drain pump needs to be started is determined based on the first water level detection value obtained periodically.
And 102, if the continuous operation time length corresponding to the drainage pump reaches or exceeds a set numerical value, controlling the drainage pump to work in a second mode, wherein in the second mode, the drainage pump circularly works at a first start-stop ratio, and the first start-stop ratio is the ratio of the operation time length to the stop time length in one period.
Here, the set value is reasonably set based on a drainage experiment of the laundry treating apparatus. If the continuous operation time of the drain pump reaches or exceeds the set value, it indicates that the water level sensor may malfunction, and if the operation is continued in the first mode, it may cause deterioration of drain noise and may affect the service life of the drain pump due to an excessively long operation time.
Based on this, in the embodiment of the present invention, when it is determined that the continuous operation duration of the drain pump reaches or exceeds the set value, the drain pump is controlled to operate in the second mode, and in the second mode, the drain pump operates cyclically at the first on-off ratio, so that the continuous operation duration of the drain pump due to a water level detection fault can be effectively reduced, thereby reducing the operation noise of the drain pump, avoiding the damage of heating and the like of the drain pump due to an excessively long continuous operation duration, and being beneficial to prolonging the service life of the drain pump.
In one embodiment, the controlling the drain pump to operate in a second mode includes:
periodically acquiring a second water level detection value corresponding to the water level, wherein the second water level detection values of two adjacent times take a second duration as an interval;
if the second water level detection value reaches or exceeds the set water level threshold value, controlling the drainage pump to work at the first start-stop ratio;
if the second water level detection value is lower than the set water level threshold value, returning to the step of controlling the drainage pump of the clothes treatment equipment to work under the first mode.
Here, if the second water level detection value is lower than the set water level threshold value, indicating that the water level sensor can still detect a water level value lower than the set water level, the operation of the drain pump is controlled based on the water level detection value by returning to the first mode.
In one embodiment, the second duration is greater than the first duration, and the stop duration in the first start-stop ratio reaches or exceeds the second duration. Therefore, the frequency of periodically acquiring the second water level detection value in the second mode is lower than the frequency of periodically acquiring the first water level detection value in the first mode, and the stop duration of the drainage pump in the second mode can be set to be longer, so that the noise is reduced, the drainage pump is prevented from being overheated, and the service life of the drainage pump is prolonged.
In an application example, in the second mode, the second time period is 8 seconds, and the operation time period and the stop time period in the first start-stop ratio are both set to 8 seconds.
Fig. 2 is a schematic view showing the control principle of the drainage control method of the laundry treating apparatus in the first rotation speed stage according to the embodiment of the present invention. In this application embodiment, the drain pump operates in the first mode, and the operation of the drain pump is controlled based on a water level detection value detected by the water level sensor. Specifically, whether the water level detection value reaches or exceeds the set water level threshold value is judged every 3 seconds, if so, the drainage pump is controlled to operate for 8 seconds, after the drainage pump continuously drains water for 40 seconds, the drainage pump enters the second mode to operate, the drainage pump operates according to a first start-stop ratio of 8 seconds and stops 8 seconds, meanwhile, whether the water level detection value is lower than the set water level threshold value is judged every 8 seconds, if the water level detection value is lower than the set water level threshold value (namely, a water-free state), the first mode is returned to operate, namely, whether the water level detection value reaches or exceeds the set water level threshold value is judged every 3 seconds, if the water level detection value reaches or exceeds the set water level threshold value (namely, a water-containing state), the drainage pump is controlled to operate for 8 seconds, and when 8 seconds end, whether the water level detection value reaches or exceeds the set water level threshold value is continuously judged, if so, if not, returning to the step of judging whether the water level detection value reaches or exceeds the set water level threshold value every 3 seconds.
The following takes a washing machine as an example to illustrate the drainage control method of the embodiment of the invention:
during the practical application, when considering that the dehydration rotational speed is higher, the accuracy of the water level value that level sensor detected reduces, is difficult to effectively control drain pump work according to the water level detected value. The drain pump of the washing machine may be controlled to operate in the first mode during a first spin speed phase in which the washing machine is determined to be spinning. The first rotating speed stage refers to a dehydrating stage in which the dehydrating rotating speed of the washing machine is lower than that corresponding to the first rotating speed value, namely the washing machine is in a low-rotating-speed dehydrating stage, and the first rotating speed value can be reasonably selected according to the preset rated rotating speed corresponding to the washing machine.
In the first mode, a first water level detection value detected by a water level sensor of the washing machine is acquired at intervals of 3 seconds, if the first water level detection value reaches or exceeds a set water level threshold value, the drainage pump is controlled to be started for 8 seconds, and when the 8 seconds are finished, whether the current water level detection value reaches or exceeds the set water level threshold value is judged, if so, the drainage pump is continuously controlled to operate for 8 seconds, and if not, the step of judging whether the first water level detection value reaches or exceeds the set water level threshold value at intervals of 3 seconds is returned. And if the continuous operation time of the drainage pump reaches 40 seconds, controlling the drainage pump to work in a second mode, wherein in the second mode, the drainage pump circularly works according to a first start-stop ratio of 8 seconds of operation and 8 seconds of stop, meanwhile, judging whether the water level detection value is lower than a set water level threshold value every 8 seconds, and if the water level detection value is lower than the set water level threshold value (namely, in a water-free state), returning to the first mode for working.
In practical application, the washing machine drainage control method may further include:
determining that the washing machine is in a second rotation speed stage of dehydration, and controlling the drainage pump to work in a third mode;
in the second rotation speed stage, the dehydration rotation speed of the washing machine is accelerated from the first rotation speed value to a preset rated rotation speed and is maintained at the preset rated rotation speed for a preset time length, and in the third mode, the drainage pump circularly works at a second start-stop ratio which is the ratio of the running time length to the stopping time length in one period.
In the second rotation speed stage, since the dehydration rotation speed is higher than that corresponding to the first rotation speed stage, the accuracy of the water level value detected by the water level sensor is reduced as the rotation speed is increased, and it is difficult to reliably control the operation of the drainage pump according to the detected water level value. In the embodiment, by controlling the drain pump to operate in the third mode, unlike controlling the drain pump according to the detected water level detection value, noise caused by semi-water vapor state operation of the drain pump can be reduced, and the control strategy is simplified.
Considering that the water level in the washing tub rises to some extent when the dewatering speed is accelerated every time, the water in the washing tub needs to be drained in time, and a certain time is required for the water in the washing tub to enter the drain pump.
Based on this, in one embodiment, the controlling the drain pump to operate in a third mode includes:
and when the dewatering rotating speed is determined to be accelerated, controlling the drainage pump to periodically stop for a second stop time period and then start for a second running time period, wherein the second start-stop ratio is the ratio of the second running time period to the second stop time period.
The drainage pump is controlled to periodically stop the second stop time period and then start the second operation time period, so that the drainage pump firstly enters the set amount of water in the second stop time period, the operation of the semi-water vapor state of the drainage pump can be effectively avoided, the water in the washing barrel can be timely discharged in the second operation time period, and the problem that air trapping leads to dewatering with water is avoided. In one example, the control device controls the drainage pump to stop for 5 seconds and then controls the drainage pump to start for 15 seconds in the dewatering rotation speed acceleration stage, and the circulation is carried out, so that the drainage pump runs intermittently at the start-stop ratio of 15: 5. Here, the second stop period and the second operation period may be set according to the total dehydration period.
In an embodiment, the dehydration control method of a washing machine may further include:
determining that the washing machine is in a third rotation speed stage of dehydration, and controlling the drainage pump to work in a fourth mode;
in the third rotation speed stage, the dewatering rotation speed of the washing machine is maintained at the preset rated rotation speed for a preset time period until the dewatering is finished, and in the fourth mode, the drainage pump circularly works at a third start-stop ratio, wherein the third start-stop ratio is the ratio of the operation time period to the stop time period in one period.
In the third rotation speed stage, because the washing machine is in the maintaining stage of the preset rated rotation speed and the water amount generated in the dewatering stage is less, the starting frequency of the drainage pump can be reduced and the noise generated in the semi-water state operation of the drainage pump can be reduced by setting the third start-stop ratio to be lower than the second start-stop ratio.
Here, the controlling the drain pump to operate in a fourth mode includes:
and controlling the drainage pump to periodically start a third running time period and then stop the third stopping time period, wherein the third start-stop ratio is the ratio of the third running time period to the third stopping time period.
In one application example, the control device controls the drainage pump to start for 10 seconds, then controls the drainage pump to stop for 10 seconds, and circulates sequentially until the dewatering is finished, so that the drainage pump runs intermittently at the start-stop ratio of 10: 10. Here, the third stop period and the third operation period may be set according to the total dehydration period.
