In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure 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 disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
In view of the problems set forth in the background section, embodiments of the present disclosure provide a dehydration control method, apparatus, medium, and device for a laundry treatment apparatus, the method including: acquiring water inflow and water drainage in the clothes treatment process; determining a residual water amount based on the water inflow amount and the water drainage amount; based on the amount of residual water, a dewatering procedure is determined. Based on the method, the residual water quantity in the clothes is determined by utilizing the water inflow and the water drainage, the method is simple and accurate, the dehydration control is performed based on the residual water quantity in the clothes, and the residual water quantity in the clothes is accurately controlled in a set range.
Hereinafter, a dehydration control method, apparatus, medium, and device of a laundry treatment apparatus according to an embodiment of the present disclosure will be exemplarily described with reference to fig. 1 to 9.
Fig. 1 is a flow chart illustrating a dehydration control method of a laundry treatment apparatus according to an embodiment of the present disclosure. Referring to fig. 1, the dehydration control method includes:
s101, acquiring water inflow and drainage in the clothes treatment process.
Wherein, the clothes treatment process at least comprises washing and dewatering links. The water inflow is the sum of all water inflow in the clothes treatment process, is the accumulated water inflow, and the water inflow of each water inflow in the clothes treatment process is obtained through a first flowmeter arranged at the water inlet, so that the accumulated water inflow is obtained; the water discharge is the sum of all water discharge in the clothes treatment process, is the accumulated water discharge, and obtains the water discharge of each water discharge in the clothes treatment process through a second flowmeter arranged at the water outlet, thereby obtaining the accumulated water discharge.
S102, determining the residual water based on the water inflow and the water drainage.
Wherein the residual water quantity in the clothes treatment equipment, namely the residual water quantity in the clothes, is determined by subtracting the water discharge quantity from the water inflow; the residual water amount is the water content of the clothes after basic dehydration.
S103, determining a dehydration program based on the residual water quantity.
Wherein the dewatering program is used for controlling dewatering, and the dewatering program at least comprises the steps of determining corresponding dewatering rotating speeds and/or dewatering time periods for different residual water amounts.
Specifically, the dehydration procedure determined in this step is to determine whether to continue dehydration according to the amount of residual water in the laundry after basic dehydration; if the residual water quantity in the clothes after basic dehydration meets the requirement, the continuous dehydration is not needed; if the residual water quantity in the clothes after basic dehydration is higher and does not meet the requirement, the clothes are required to be dehydrated continuously, and the dehydration is carried out according to a dehydration program corresponding to the residual water quantity, so that the residual water quantity in the clothes meets the requirement.
When the residual water quantity in the clothes is large, if the high-rotation-speed dehydration is carried out, the washing water in the clothes treatment barrel cannot be discharged, and the motor is dehydrated at a high speed with water, so that the current and the power of the motor are increased, the driver is protected from over-temperature, the motor stops rotating, and even the motor is damaged, so that the service life of the motor is influenced. Therefore, when the residual water quantity in the clothes is larger, the corresponding dehydration rotating speed is smaller, the dehydration time is longer, the washing water is discharged as soon as possible, and the dehydration of the motor with water is avoided.
The embodiment of the disclosure provides a dehydration control method of a laundry treatment apparatus, the method comprising: acquiring water inflow and water drainage in the clothes treatment process; determining a residual water amount based on the water inflow amount and the water drainage amount; based on the amount of residual water, a dewatering procedure is determined. Based on the method, the residual water quantity in the clothes is determined by utilizing the water inflow and the water drainage, the method is simple and accurate, the dehydration control is performed based on the residual water quantity in the clothes, and the residual water quantity in the clothes is accurately controlled in a set range.
In one embodiment, as shown in fig. 2, a detailed flowchart of S103 is shown in the dehydration control method of the laundry treatment apparatus shown in fig. 1. Referring to fig. 2, S103 "determine dehydration procedure based on residual water amount", includes:
s201, judging whether the residual water quantity is larger than a preset water quantity threshold value.
Wherein the preset water quantity threshold is determined based on the weight of the dried clothes before water inflow, and the preset water quantity threshold is equal to the product of the weight of the dried clothes and the water content threshold; the water content threshold value not only meets the dehydration standard of the clothes treatment equipment (such as clothes do not drip), but also meets the drying effect and energy consumption requirements of the subsequent drying stage, and the water content threshold value can be preset by design and research personnel or set by users independently, and is not limited herein. Or presetting the association relation between the weight of the dry clothes and the preset water quantity threshold by a designer, and determining the preset water quantity threshold according to the association relation between the weight of the dry clothes and the preset water quantity threshold after acquiring the weight of the dry clothes.
In this step, based on the comparison result of the residual water amount and the preset water amount threshold, whether to continue dehydration is judged, specifically: if the residual water amount is equal to or less than the preset water amount threshold, the dehydration is ended (i.e., S202 is performed); if the residual water amount is greater than the preset water amount threshold, S203 is performed.
S202, dehydrating is finished.
S203, dehydrating at a preset dehydration rotating speed and dehydration time.
In the step, when the residual water quantity is larger than a preset water quantity threshold value, the water content of the clothes is too high, and the clothes are required to be dehydrated continuously, and dehydration is carried out under preset running conditions (at least comprising dehydration rotating speed and dehydration time length); after the dehydration is finished, the process returns to the S201, and whether the dehydration is continued or not is judged until the residual water quantity is equal to or less than a preset water quantity threshold value, and the dehydration is finished.
In one embodiment, as shown in fig. 3, a detailed flowchart of "determine whether to continue dewatering based on the residual water amount and the preset water amount threshold value" is shown. Referring to fig. 3, the preset water volume threshold includes at least a first preset water volume threshold and a second preset water volume threshold, the first preset water volume threshold being greater than the second preset water volume threshold; s201 "determining whether to continue dehydration based on the residual water amount and a preset water amount threshold value" includes:
S301, judging whether the residual water quantity is larger than a first preset water quantity threshold value.
Specifically, if the residual water amount is greater than the first preset water amount threshold, the determination result is yes, and S302 is executed; if the residual water amount is equal to or smaller than the first preset water amount threshold, the determination result is no, and S303 is executed.
S302, dehydrating at a first dehydration rotating speed and a first dehydration time period.
In this step, dehydration is performed according to the first dehydration rotational speed and the first dehydration duration, after the first dehydration duration (i.e., the current dehydration is completed), the water displacement in the current dehydration process is obtained, the water displacement in the current dehydration process is subtracted from the residual water quantity determined in S102, so as to obtain an updated residual water quantity, and then S303 is executed.
S303, judging whether the residual water quantity is larger than a second preset water quantity threshold value.
Specifically, if the residual water amount is greater than the second preset water amount threshold, and the residual water amount is between the first preset water amount threshold and the second preset water amount threshold, executing S304; if the residual water amount is equal to or smaller than the second preset water amount threshold, the determination result is no, and S305 is executed.
S304, dehydrating at a second dehydration rotating speed and a second dehydration time period.
In this step, dehydration is performed according to the second dehydration rotational speed and the second dehydration duration, after the second dehydration duration (i.e. the current dehydration is completed), the drainage amount in the current dehydration process is obtained, the drainage amount in the current dehydration process is subtracted from the residual water amount determined in S102 (or the residual water amount determined in S302, or the residual water amount obtained in S304 in the previous cycle), so as to obtain an updated residual water amount, and then the execution returns to S303.
S305, dehydrating is finished.
In order to avoid the situation that the motor dehydrates at a high speed with water, the residual water amount corresponding to S302 is larger than that of S304, so that the dehydration rotation speed of S302 is smaller than that of S304, that is, the second dehydration rotation speed is larger than the first dehydration rotation speed; in addition, in order to drain the washing water as much as possible at the time of low-speed dehydration, the dehydration period is appropriately prolonged, so that the first dehydration period is longer than the second dehydration period.
It can be understood that fig. 3 illustrates that the preset water amount threshold value includes a first preset water amount threshold value and a second preset water amount threshold value by way of example only, but is not enough to limit the dehydration control method of the laundry treating apparatus provided by the embodiments of the present disclosure. In other embodiments, the number of preset water volume thresholds may be flexibly set according to the needs, which is not limited herein.
In one embodiment, as shown in fig. 4, another refinement flow chart of "determine whether to continue dehydration based on the residual water amount and the preset water amount threshold value". Referring to fig. 4, the dehydration control method further includes:
S403/S408, dewatering is carried out at a third dewatering rotation speed and a third dewatering time period.
The third dehydration rotating speed is larger than the second dehydration rotating speed, and the third dehydration duration is smaller than the second dehydration duration.
Specifically, after S402 "dehydration at the first dehydration speed and the first dehydration duration" and S407 "dehydration at the second dehydration speed and the second dehydration duration", a high-speed dehydration stage is added, where the dehydration speed at the stage is the third dehydration speed, and the dehydration duration is the third dehydration duration; the third dehydration rotational speed is greater than the first dehydration rotational speed and the second dehydration rotational speed, and the third dehydration duration is less than the first dehydration duration and the second dehydration duration; the reason for this is that the residual water in the clothes is mainly discharged during the long-time dehydration in the previous dehydration stage (the stage of dehydration at the first dehydration speed and the first dehydration time period or the stage of dehydration at the second dehydration speed and the second dehydration time period), the water discharge in this stage is stabilized, the residual water is not basically discharged, and the long dehydration time is not required.
In one embodiment, as shown in fig. 4, before the dehydration is performed at the second dehydration rotational speed and the second dehydration period, the dehydration control method further includes:
S405, acquiring actual dewatering times.
If the determination result in S404 is no, that is, the residual water amount is greater than the second preset water amount threshold, it is determined that continuous dehydration is required, and the actual dehydration times are obtained before S407 "dehydration is performed at the second dehydration rotation speed and the second dehydration duration"; the actual dehydration times can be obtained by an accumulation method, specifically: the initial value of the actual dewatering number is set to 0, and the corresponding actual dewatering number is increased once each time the residual water amount is judged to be larger than the second preset water amount threshold value. In other embodiments, the method for obtaining the actual number of dehydration times includes all methods known to those skilled in the art, and is not limited herein.
S406, judging whether the actual dewatering times are smaller than the preset dewatering times.
In the step, judging whether to continue dehydration according to the actual dehydration times and the preset dehydration times; specifically, if the actual number of dehydration is equal to or greater than the preset number of dehydration, and the determination result is no, S409 is performed and the dehydration is ended; if the actual number of times of dehydration is less than the preset number of times of dehydration, the determination result is yes, then S407 is executed.
Wherein, the preset dewatering times can be set according to the clothes treatment stage, for example, the preset dewatering times in the washing stage have smaller values, so that excessive power consumption caused by multiple dewatering is avoided; in the washing and drying stage, the residual water amount in the clothes can influence the drying effect and the power consumption of the subsequent drying stage, and the proportion of the power consumption in the whole washing and drying stage for dehydration is very small, so that the preset dehydration times in the washing and drying stage take a larger value to ensure that the residual water amount in the treated clothes meets the requirement (the residual water amount is equal to or smaller than a second preset water amount threshold), thereby reducing the power consumption of the drying stage and ensuring that the clothes can be dried.
Illustratively, as shown in fig. 4, "judging whether to continue dehydration based on the residual water amount and a preset water amount threshold value" includes:
S401, judging whether the residual water quantity is larger than a first preset water quantity threshold value.
Specifically, if the residual water amount is greater than the first preset water amount threshold, the determination result is yes, S402 is executed; if the residual water amount is equal to or smaller than the first preset water amount threshold, the determination result is no, and S404 is executed.
S402, dehydrating at a first dehydration rotating speed and a first dehydration time period.
S403, dehydrating at a third dehydration rotating speed and a third dehydration time period.
The third dehydration rotating speed is larger than the first dehydration rotating speed, and the third dehydration duration is smaller than the first dehydration duration. After the first dehydration period+the third dehydration period, the amount of water discharged in the current dehydration process is obtained, the amount of water discharged in the current dehydration process is subtracted from the amount of residual water determined in S102 to obtain an updated amount of residual water, and then S404 is executed.
S404, judging whether the residual water quantity is larger than a second preset water quantity threshold value.
Specifically, if the residual water amount is greater than the second preset water amount threshold, the determination result is yes, S405 is executed; if the residual water amount is equal to or less than the second preset water amount threshold, the determination result is no, and S409 is performed.
S405, acquiring actual dewatering times.
S406, judging whether the actual dewatering times are smaller than the preset dewatering times.
Specifically, if the actual number of dehydration is equal to or greater than the preset number of dehydration, and the determination result is no, S409 is performed and the dehydration is ended; if the actual number of times of dehydration is less than the preset number of times of dehydration, the determination result is yes, then S407 is executed.
S407, dehydrating at a second dehydration rotating speed and a second dehydration time period.
And S408, dehydrating at a third dehydration rotating speed and a third dehydration time period.
The third dehydration rotating speed is larger than the second dehydration rotating speed, and the third dehydration duration is smaller than the second dehydration duration. After the second dehydration period+the third dehydration period, the amount of water discharged in the present dehydration process is obtained, the amount of water discharged in the present dehydration process is subtracted from the amount of water remaining determined in S102 (or the amount of water remaining determined in S403 or the amount of water remaining obtained in the previous cycle in S408), an updated amount of water remaining is obtained, and then S404 is executed.
S409, dehydrating is finished.
It can be understood that fig. 4 shows only exemplary cases where the steps of determining whether the actual number of dehydration times is less than the preset number of dehydration times at S405 "the actual number of dehydration times at S406" the residual water amount is greater than the second preset water amount threshold value at S404 "and before the dehydration is performed at the second dehydration rotational speed and the second dehydration time period at S407", but is not limited to the dehydration control method of the laundry treatment apparatus provided by the embodiment of the present disclosure. In other embodiments, S405 and S406 may also be disposed between S408 and S404, which is not limited herein.
