Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
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 meaning is generally understood by those skilled in the art. 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 following description, references to the terms "first, second, third, etc. are only used to distinguish between similar elements and not necessarily for describing a particular order, but it is understood that" first, second, third, etc. may be interchanged with respect to a particular order or sequence, where permissible, to enable embodiments of the invention described herein to be practiced otherwise than as shown or described herein.
An embodiment of the present invention provides a dehydration control method for a clothes treatment device, which is applied to a control device of the clothes treatment device, and as shown in fig. 1, the dehydration control method includes:
controlling the clothes treatment device to be in a first spinning speed stage of dehydration;
acquiring a water level value in the washing barrel;
determining that the water level value is equal to or greater than a set water level threshold value, controlling a drainage pump to start for a first set time period, and then returning to the step of acquiring the water level value in the washing tub;
determining that the water level value is smaller than a set water level threshold value, controlling the drainage pump to stop for a second set time period, and then returning to the step of acquiring the water level value in the washing tub;
the first rotation speed stage is a dehydration stage in which the dehydration rotation speed of the clothes treatment device is less than a corresponding first rotation speed value, that is, the clothes treatment device is in a low rotation speed dehydration stage, and the first rotation speed value can be reasonably selected according to a preset rated rotation speed corresponding to the clothes treatment device. The method comprises the steps of obtaining a water level value in a washing barrel, comparing the water level value with a set water level threshold value, and controlling a drainage pump to be started for a first set time length under the condition that the water level value is equal to or larger than the set water level threshold value. And when the drainage pump is started for the first set time length, the acquired water level value is inaccurate, so that the water level value does not need to be acquired during the starting of the drainage pump, and the step of acquiring the water level value in the washing tub is returned to be executed only when the first set time length is finished. Therefore, the frequent starting of the drainage pump can be effectively avoided, and the drainage pump is protected. And comparing the obtained water level value with a set water level threshold value again, controlling the drainage pump to operate for the first set time length when the water level value reaches or exceeds the set water level threshold value, and controlling the drainage pump to stop for the second set time length. Therefore, the operation of the drainage pump in the semi-water semi-vapor state can be effectively avoided, the noise is reduced, meanwhile, the water level value is obtained only when the drainage pump is started for the first set time and stopped for the second set time, the water level value is not required to be obtained in real time, and the control logic is simple.
Fig. 6 is a water discharge simulation diagram of the dewatering control of the laundry treating apparatus in the first rotation speed stage. When the water level value in the washing barrel is lower than a set water level threshold value (namely no water) at the beginning (namely 0 second), controlling the drainage pump to stop for a second set time period, wherein the second set time period is 3 seconds, the water level value is obtained when the 3 seconds are ended, and the drainage pump continues to stop for 3 seconds if the judgment result is no water; acquiring a water level value after 3 seconds (namely 6 seconds), and continuing to stop for 3 seconds if the water level value is judged to be anhydrous; and acquiring a water level value after 3 seconds (namely 9 seconds), controlling the drainage pump to drain water for a first set time length if the water level value is equal to or greater than a set water level threshold (namely water exists), wherein in the embodiment, the first set time length is 8 seconds, and acquiring the water level value after the first set time length, and continuing to operate according to the following steps: if the water level value is equal to or greater than the set water level threshold value, controlling the drainage pump to start for a first set time; and if the water level value is smaller than the set water level threshold value, controlling the drainage pump to stop for a second set time, and acquiring the water level value in the washing tub after the first drainage pump is started for the first set time or the first set time. And after the water level value is obtained, judging whether water exists or does not exist, and continuing to operate according to the steps.
In practical application, the clothes treatment device enters a dehydration stage under program control, a water level detection sensor of the clothes treatment device acquires the water level in the washing tub and transmits the detected water level value to the control device, and whether the water level in the washing tub is equal to or greater than a set water level threshold value is judged according to the received water level value.
Here, the set water level threshold may be reasonably selected or experimentally determined according to the volume of the washing tub of the laundry treatment apparatus. In a possible embodiment, the set water level threshold is a water level value in the washing tub detected by the water level sensor when a set amount of water (e.g. 700ml) is added into the washing tub in a factory state.
The drainage pump starts often can receive the influence of voltage fluctuation, under different voltage operating modes, and the start speed of drainage pump can receive the influence promptly. Based on this, in one possible 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 one embodiment, the set duration is equal to or greater than the time interval between two adjacent water level acquisitions, so that frequent starting of the drainage pump can be avoided, the service life of the drainage pump is prolonged, and the drainage pump is controlled to be started for the set duration only when the water level value is equal to or greater than the set water level threshold value by acquiring the water level value in the washing barrel, so that the operation of the drainage pump in the semi-water and semi-steam state in the first rotating speed stage is effectively avoided, and noise reduction is facilitated.
Fig. 2 is a flow chart illustrating a dehydration control method of the laundry treating apparatus in the first rotation speed stage according to an embodiment, as shown in fig. 2, the control method includes:
the water level sensor can transmit the detected water level value to the control device, or the control device actively acquires the water level value currently generated by the water level sensor.
Step 202, whether the water level value is equal to or greater than a set water level threshold value or not is judged;
comparing the water level value obtained in step 201 with a set water level threshold value to determine the magnitude relationship between the two.
Step 203, controlling the drainage pump to be started for a first set time;
if the water level value in the washing barrel is equal to or greater than the set water level threshold value, the control device controls the drainage pump to be started for a first set time period, for example, the control device controls the drainage pump to be started for 8 seconds. Therefore, noise caused by operation of the drainage pump in a semi-water and semi-steam state is avoided, and dewatering with water in the washing barrel can be effectively avoided by intermittently opening the drainage pump.
The water level value is not accurate during the first set time period of the drainage pump starting, so the water level value is not required to be acquired during the drainage pump starting, and the step of acquiring the water level value in the washing tub is returned to be executed after the first set time period.
Step 204, controlling the drainage pump to stop for a second set time;
if the water level value in the washing tub is less than the set water level threshold, the control device controls the drain pump to stop for a first set time period, for example, the control device controls the drain pump to stop for 3 seconds. Therefore, the operation of the drainage pump in the semi-water and semi-steam state in the first rotating speed stage can be effectively avoided, and the noise is favorably reduced.
And returning to the step of acquiring the water level value in the washing tub after the drain pump is stopped for the second set time period.
Step 205, maintaining the dehydration rotation speed at the first rotation speed value for a second preset time period;
after the control device detects that the dehydration speed runs for a second set time period t2 at the first speed value, the control device controls the clothes treatment device to enter a second speed stage. In some embodiments, the first speed value is 600rpm, and the second speed stage is entered after the first speed value is maintained for a period of 10 seconds.
In a possible embodiment, as shown in fig. 1, the dewatering control method further includes:
step 102, controlling the clothes treatment device to be in a second rotation speed stage of dehydration, and simultaneously controlling the drainage pump to work in a first mode;
in the second rotation speed stage, the dehydration rotation speed of the clothes treatment device 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 first preset time, and in the first mode, the ratio of the running time length and the stopping time length of the drainage pump in one cycle period is a first start-stop ratio.
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. By controlling the drain pump to operate in the first mode, the present embodiment can reduce noise caused by the semi-water vapor state operation of the drain pump, and simplify the control strategy, as opposed to controlling the drain pump according to the acquired water level value.
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 a possible embodiment, the control drain pump operates in a first mode, comprising:
and when the dewatering rotating speed is determined to be accelerated, controlling the drainage pump to stop for a first stop time period and then start for a first operation time period, wherein the first start-stop ratio is the ratio of the first operation time period to the first stop time period.
The draining pump is controlled to stop for the first time period and then start for the first operation time period before the dewatering rotating speed is accelerated, water extruded from clothes before acceleration can be drained into the draining pump, the operation of the draining pump in a semi-water vapor state can be effectively avoided, and the phenomenon that air trapping causes dewatering with water is avoided. Here, the first stop period and the first operation period may be set according to the total dehydration period.
In a possible embodiment, as illustrated in fig. 1, the method for controlling dehydration further comprises:
103, controlling the clothes treatment device to be in a third rotation speed stage of dehydration, and simultaneously controlling the drainage pump to work in a second mode;
in the second mode, the ratio of the operation time length and the stop time length of the drainage pump in one cycle period is a second start-stop ratio, and the second start-stop ratio is smaller than the first start-stop ratio.
In the third rotation speed stage, since the clothes treating apparatus is in the maintaining stage of the preset rated rotation speed and the amount of water generated by dehydration in the stage is small, the second on-off ratio is set to be smaller than the first on-off ratio, so that the starting frequency of the drain pump can be reduced, and the noise generated by the semi-water and semi-steam operation of the drain pump can be reduced.
And controlling the drainage pump to start for a second operation time period and then stop for a second stop time period, wherein the second start-stop ratio is the ratio of the second operation time period to the second stop time period.
In one possible embodiment, the control device controls the drain pump to start for 10 seconds, then controls the drain pump to stop for 10 seconds, and circulates sequentially until the dewatering is finished, so that the drain pump operates at a start-stop ratio of 10: 10. Here, the second stop period and the second operation period may be set according to the total dehydration period.
FIG. 3 is a schematic diagram illustrating a rotation speed curve corresponding to a dehydration control method according to an embodiment of the present invention. As shown in fig. 3, the dehydration control method includes:
1. first speed stage S1:
the first rotating speed stage is the corresponding dewatering stage when the dewatering rotating speed is below 600rpm (revolutions per minute), and the stage controls the operation of the drainage pump through the acquired water level value. Specifically, the clothes treatment device maintains a period of time at 90rpm, performs eccentric identification detection, determines a preset rated rotating speed corresponding to dehydration according to an identification result, accelerates the dehydration rotating speed from 90rpm to 400rpm and maintains the same for 60 seconds, and the process is repeated twice; then accelerated to 400rpm, 600rpm in this order. In the first rotating speed stage, the control device compares the acquired water level value with a set water level threshold value, and if the water level value is equal to or greater than the set water level threshold value, the drainage pump is controlled to be started for 8 seconds; and if the water level value is lower than the set water level threshold, controlling the drainage pump to stop for 3 seconds, not acquiring the water level value during the running or stopping of the drainage pump, only starting for 8 seconds, stopping acquiring the water level value for 3 seconds, comparing the acquired water level value with the set water level threshold, and then continuously controlling the drainage pump according to the method. And entering a second rotating speed stage until the dewatering rotating speed reaches 600 rpm.
2. Second rotational speed stage S2:
the second rotation speed stage is a stage corresponding to the spin-drying rotation speed accelerated from 600rpm to the preset rated rotation speed of 1200rpm and maintained at 1200rpm for a set time period t1 (such as 20 seconds). In the stage, the water level detection value is not accurate enough due to the high rotating speed, and the start-stop of the drainage pump is controlled by a fixed start-stop ratio of 15: 5. And in each rotation speed increasing stage (namely, the acceleration stage), the drainage pump is stopped for 5 seconds, then the drainage pump is started for 15 seconds, and the steps are sequentially and circularly executed until the rotation speed is in the third rotation speed stage.
3. Third speed stage S3:
the third rotation speed stage refers to a corresponding dehydration stage after the dehydration rotation speed is maintained at the preset rated rotation speed for the first preset time, for example, the dehydration rotation speed is maintained at 1200rpm for 60 seconds, and then the third rotation speed stage is a dehydration stage corresponding to the remaining 40 seconds after the dehydration rotation speed is maintained at 1200rpm for 20 seconds. And in the third rotating speed stage, the starting and stopping of the drainage pump are controlled by a fixed starting and stopping ratio of 10:10, because the third rotating speed stage is the later stage of high-speed rotating speed maintenance and the water quantity in the later stage is reduced. Specifically, the drainage pump is started for 10 seconds, then stopped for 10 seconds, and is sequentially and circularly executed until the dehydration is finished.
