Description

TECHNICAL FIELD

The disclosure relates to the field of laundry washing, and in particular to a method and an apparatus for detecting an amount of laundry of a washing device, a device and a storage medium.

BACKGROUND

A washing device often needs to determine an amount of laundry (also referred to as a load amount) in an inner drum of the washing device when washing the laundry, thereby selecting appropriate water-level grade, washing duration and other washing parameters according to the amount of laundry to achieve the purposes of saving the energy, reducing the emission and improving the washing effect.
In the relevant art, in order to detect the amount of laundry in the inner drum, the washing device uses the following solutions:
The first solution: the washing device determines the amount of laundry by collecting an electrical signal of a motor, for example, the washing device determines the amount of laundry based on a working current of the motor.
The second solution: the washing device determines the amount of laundry based on a number of times of water supplementing and a water supplementing duration in a water supplement washing stage.
The first solution needs to configure an additional collection circuit, which increases the hardware cost of the washing device. The second solution is limited by the precision of a water level sensor, which results in a limited discrimination for the number of times of water supplementing and the water supplementing duration among different amounts of laundry, thereby causing misjudgment easily.

SUMMARY

In view of this, the embodiments of the disclosure provide a method and an apparatus for detecting an amount of laundry of a washing device, a device and a storage medium, to improve the precision of detection on the amount of laundry without increasing the hardware cost of the washing device.

DETAILED DESCRIPTION

The disclosure will be further described below in combination with the accompanying drawings and embodiments.
Unless otherwise defined, all technical and scientific terms used in the disclosure have a same meaning generally appreciated by a person skilled in the art to which the disclosure belongs. The terms used in the specification of the disclosure are merely to describe the specific embodiments, rather than to limit the disclosure.
The embodiments of the disclosure provide a method for detecting an amount of laundry of a washing device. The washing device may be a washing machine or a washing-drying integrated machine. For example, the washing device may be a drum type washing machine or an impeller type washing machine. As shown in FIG. 1, the method may include the following operations.
At 101, the washing device is controlled to be supplied with water to a first set water level.
Herein, the first set water level is configured such that when the amount of laundry of the washing device is at a first load level, no water supplementation is required during the water supplement washing, and when the amount of laundry of the washing device is at a second load level, a water supplementation is necessary during the water supplement washing; and the amount of laundry corresponding to the second load level is greater than that corresponding to the first load level. The first set water level may be determined based on tests of washing devices in the same batch.
In some embodiments, the amount of laundry may be a weight of laundry or a volume of laundry without taking the influence of a material of the laundry into consideration. In order to further improve the precision of detection on the amount of laundry, in some other embodiments, the amount of laundry may be a weight of laundry or a volume of laundry taking the influence of the material of the laundry into consideration. For example, an influencing factor may be set according to water absorbing capacities of different materials. The amount of laundry may be determined according to the influencing factor, the weight of laundry or the volume of laundry.
Herein, the first set water level may be determined based on an amount of water required by a primary washing at the first load level and an amount of water required by the primary washing at the second load level. The amount of water required by the primary washing at the first load level and the amount of water required by the primary washing at the second load level may be determined according to the corresponding amount of laundry. That is, by controlling an amount of water supply reasonably, the supplied water of the washing device may reach the first set water level.
Herein, a relationship between the primary washing and the water supplement washing may be appreciated below. A laundry treatment process may include a water supplement washing stage, a primary washing stage, a rinsing stage and a dewatering stage, etc. The water supplement washing is intended to make the amount of water and/or the water level meet the requirement of the primary washing.
In some embodiments, the operation that the washing device is controlled to be supplied with water to reach the first set water level may include the following operations.
The washing device is controlled to be supplied with the water to an amount of water supply corresponding to the first set water level, the amount of water supply corresponding to the first set water level being greater than an amount of water required by the primary washing at the first load level, and the amount of water supply corresponding to the first set water level being smaller than an amount of water required by the primary washing at the second load level.
Herein, the amount of water required by the primary washing refers to an amount of water required during the primary washing of the laundry. The laundry treatment process may include the water supplement washing stage, the primary washing stage, the rinsing stage and the dewatering stage. The water supplement washing is intended to make the amount of water and/or the water level meet the requirement of the primary washing.
In an application example, the load level of the washing device includes a light load, a medium load and a heavy load. For example, for a washing machine having a capacity of 8 Kg, the light load may correspond to the amount of laundry <2 Kg, the medium load may correspond to 2Kg≤the amount of laundry<4 Kg, and the heavy load may correspond to the amount of laundry>4Kg. Each load level has a corresponding amount of water required by the primary washing. The amount of water required by the primary washing corresponding to the light load is Q2, the amount of water required by the primary washing corresponding to the medium load is Q3, and the amount of water required by the primary washing corresponding to the heavy load is Q4. Supposing that the amount of water supply corresponding to the first set water level L1 is Q1, then Q2<Q1<Q3.
In some embodiments, the washing device may control a water supply duration of a water inlet value, such that the washing device is supplied with the water to reach the first set water level. If the amount of water supply corresponding to the first set water level L1 is Q1, the first set water level L1 may be achieved by controlling the amount of water supply Q1.
At 102, the washing device is controlled to perform water supplement washing, and a number of times of water supplementing and/or an accumulated water supplementing duration during a water supplement washing are acquired.
After the washing device is supplied with the water to reach the first set water level, the water supplement washing is started. During the water supplement washing, as the laundry absorbs the water, the water level in the inner drum of the washing device is lowered, and thus it is frequent that the water is supplemented for multiple times. As the lowering of the water level is caused by the absorption of water by the laundry, the lowering of the water level is relevant to the magnitude of the amount of laundry. In the relevant art, as there is a small change amplitude, for example, less than 2 Kg, between the amount of laundry corresponding to the first load level and the amount of laundry corresponding to the second load level, if the load level is determined based on the number of times of water supplementing or the accumulated water supplementing duration and a threshold interval corresponding to the load level, the misjudge occurs frequently.
In the embodiment of the disclosure, the first set water level may be controlled reasonably such that when the amount of laundry of the washing device is at the first load level, no water supplementation is required during the water supplement washing, and when the amount of laundry of the washing device is at the second load level, a water supplementation is required during the water supplement washing.
In some embodiments, the operation that the washing device is controlled to perform the water supplement washing and the number of times of water supplementing and/or the accumulated water supplementing duration during the water supplement washing are acquired may include the following operations.
The washing device is controlled to supplement water until a target supplementing water level is reached in response to a determination that a water level of the washing device is lowered to a second set water level.
It is determined that the water supplement washing is performed for a set duration, and then the number of times of water supplementing and/or the accumulated water supplementing duration during the water supplement washing are counted.
The second set water level is smaller than the first set water level, and the target supplementing water level is greater than or equal to the first set water level.
In an application example, the target supplementing water level may be the first set water level, and a difference value between the first set water level and the second set water level is a water supplementing return difference δ.
During the water supplement washing, when it is detected by a water level sensor that the water level in the inner drum is lower than the first set water level by -δ, the washing device controls the water inlet valve to be opened so as to supplement the water; and when it is detected by a water level sensor that the water level in the inner drum reaches the first set water level, the washing device controls the water inlet valve to be closed. The above operation is carried out repeatedly until the set duration for the water supplement washing is ended. During the water supplement washing, the washing device may count the number of times of water supplementing by a counter. The washing device may further count the accumulated water supplementing duration by a timer. Herein, the accumulated water supplementing duration may be obtained by timing of a separate timer. In other embodiments, considering that the water supply duration of the washing device when it is supplied with the water to reach the first set water level is approximately same every time, it may be possible to use a timer for counting a total water supply duration to count the accumulated water supplementing duration. That is, the accumulated water supplementing duration of the washing device may be obtained by subtracting the water supply duration when the water reaches the first set water level from a timing result of the timer for counting the total water supply duration.
In other embodiments, the target supplementing water level may also be greater than the first set water level to reduce the number of times of water supplementing during the water supplement washing.
At 103, based on whether the number of times of water supplementing and/or the accumulated water supplementing duration are zero, a load level corresponding to an amount of laundry of the washing device is determined.
Herein, the washing device may determine whether the amount of laundry of the washing device is at the first load level, based on a result on whether the number of times of water supplementing and/or the accumulated water supplementing duration are zero. If the number of times of water supplementing and/or the accumulated water supplementing duration are zero, it is determined that the amount of laundry of the washing device is at the first load level.
In an actual application, the detection apparatus has an intrinsic error, and there is a small difference between the amount of laundry for the first load level and the amount of laundry for the second load level. As a result, during the water supplement washing, the water supplementing misjudge occurs due to the intrinsic error of the detection apparatus, and distinguishing the first load level from the second load level based on an amplitude of variation of the number of times of water supplementing and/or the accumulated water supplementing duration has a problem of inconspicuous discrimination. In the embodiment of the disclosure, by setting the first set water level reasonably, when the washing device is at the first load level, no water supplementation is required during the water supplement washing, and when the washing device is at the second load level, a water supplementation is required during the water supplement washing. Hence, it may be determined whether the amount of laundry of the washing device is at the first load level based on the result on whether the number of times of water supplementing and/or the accumulated water supplementing duration during the water supplement washing are zero, which improves the discrimination between the first load level and the second load level, and improves the reliability of detection on the amount of laundry.
In some embodiments, the operation that the load level corresponding to the amount of laundry of the washing device is determined based on whether the number of times of water supplementing and/or the accumulated water supplementing duration are zero may include the following operations.
It is determined that the amount of laundry of the washing device is at the first load level in response to a determination that the number of times of water supplementing and/or the accumulated water supplementing duration are zero.
The load level corresponding to the amount of laundry of the washing device is determined based on the number of times of water supplementing and/or the accumulated water supplementing duration and a set threshold, in response to a determination that the number of times of water supplementing and/or the accumulated water supplementing duration are not zero.
Herein, the washing device may determine whether the number of times of water supplementing is zero by the counter, and/or whether the accumulated water supplementing duration is zero by the timer.
In some embodiments, it may be determined that the amount of laundry of the washing device is at the first load level based on the fact that the number of times of water supplementing is zero.
In some other embodiments, it may be determined that the amount of laundry of the washing device is at the first load level based on the fact that the accumulated water supplementing duration is zero.
In some other embodiments, it may be determined that the amount of laundry of the washing device is at the first load level based on the fact that the number of times of water supplementing is zero and the accumulated water supplementing duration is zero.
In some embodiments, the operation that the load level corresponding to the amount of laundry of the washing device is determined based on the number of times of water supplementing and/or the accumulated water supplementing duration and the set threshold may include the following operations.
It is determined whether the number of times of water supplementing is greater than or equal to a first number-of-times threshold, and/or whether the accumulated water supplementing duration is greater than or equal to a first duration threshold.
If no, i.e., the number of times of water supplementing is smaller than the first number-of-times threshold, and/or the accumulated water supplementing duration is smaller than the first duration threshold, it is determined that the amount of laundry of the washing device is at the second load level.
Herein, the first load level and the second load level may be distinguished based on whether the water is supplemented during the water supplement washing. When the washing device further includes an another load level at which the amount of laundry is greater than the amount of laundry at the second load level, a threshold of the corresponding load level may be set. The second load level is distinguished from the another load level based on the threshold.
In an embodiment, the washing device further includes a third load level at which the amount of laundry is greater than the amount of laundry at the second load level, and a first number-of-times threshold corresponding to a number of times of water supplementing at the third load level and a first duration threshold corresponding to an accumulated water supplementing duration at the third load level may be determined based on a test.
If the number of times of water supplementing counted by the washing device is smaller than the first number-of-times threshold, and/or the accumulated water supplementing duration counted by the washing device is smaller than the first duration threshold, it is determined that the amount of laundry of the washing device does not reach the third load level, and thus it is determined that the amount of laundry of the washing device is at the second load level.
If the number of times of water supplementing counted by the washing device is greater than or equal to the first number-of-times threshold, and/or the accumulated water supplementing duration counted by the washing device is greater than or equal to the first duration threshold, it is determined that the amount of laundry of the washing device reaches the third load level.
In an actual application, the washing device may determine that the amount of laundry of the washing device reaches the third load level, in response to a determination that the number of times of water supplementing is greater than or equal to the first number-of-times threshold and the accumulated water supplementing duration is greater than or equal to the first duration threshold. In this way, the reliability for determining the load level may be improved.
In some embodiments, the load levels of the washing device may further include an another load level at which the amount of laundry is greater than the amount of laundry at the third load level. For example, the load levels of the washing device further include a fourth load level. A threshold of the fourth load level may be set and the third load level may be distinguished from the fourth load level based on the threshold.
Herein, a second number-of-times threshold corresponding to a number of times of water supplementing at the fourth load level and a second duration threshold corresponding to an accumulated water supplementing duration at the fourth load level may be determined based on a test. The second number-of-times threshold is greater than the first number-of-times threshold, and the second duration threshold is greater than the first duration threshold.
The operation that the load level corresponding to the amount of laundry of the washing device is determined based on the number of times of water supplementing and/or the accumulated water supplementing duration and the set threshold may further include the following operations.
If the number of times of water supplementing is greater than or equal to the first number-of-times threshold, and/or the accumulated water supplementing duration is greater than or equal to the first duration threshold, it is determined whether the number of times of water supplementing is greater than or equal to the second number-of-times threshold, and/or whether the accumulated water supplementing duration is greater than or equal to the second duration threshold.
If yes, it is determined that the amount of laundry of the washing device is at the fourth load level.
If no, it is determined that the amount of laundry of the washing device is at the third load level.
In some embodiments, the method may further include the following operation.
Based on a determined load level, the washing device is controlled to operate a corresponding washing control procedure.
As different load levels correspond to different amounts of laundry, when the washing device works, corresponding washing parameters may be set, including but not limited to: a heating duration, a washing beat, a washing water level, etc. Therefore, the electric energy and washing time may be saved, and the washing efficiency may be improved.
The disclosure will be further described below in combination with an application embodiment.
In the application embodiment, the washing device is the drum type washing machine. The washing device includes four load levels at which the amounts of laundry are increased sequentially: a first load level R1, a second load level R2, a third load level R3 and a fourth load level R4. Taking the 8-Kg drum type washing machine as an example, the R1 corresponding to the amount of laundry <2 Kg, the R2 corresponding to 2 Kg≤the amount of laundry<4 Kg, the R3 corresponding to 4 Kg≤the amount of laundry<6 Kg, and the R4 corresponding to the amount of laundry >6 K may be set. The first set water level is L1, the first number-of-times threshold corresponding to the R3 is c1, and the first duration threshold corresponding to the R3 is t1; and the second number-of-times threshold corresponding to the R4 is c2, and the second duration threshold corresponding to the R4 is t2. As shown in FIG. 2, the method for detecting the amount of laundry of the washing device may include the following operations.
At 201, the washing device is controlled to be supplied with water to reach the L1.
Herein, the L1 is greater than an amount of water required by primary washing corresponding to the R1 and is smaller than an amount of water required by primary washing corresponding to the R2, such that when the amount of laundry of the washing device is at the R1, no water supplementation is required during the water supplement washing, and when the amount of laundry of the washing device is at the R2, a water supplementation is required during the water supplement washing.
At 202, the washing device is controlled to perform water supplement washing, and a number of times of water supplementing and/or an accumulated water supplementing duration during the water supplement washing are acquired.
During the water supplement washing, the washing device has a water supplementing return difference of δ. When it is detected by the water level sensor that the water level in the inner drum is lower than the L1 by -δ, the washing device controls the water inlet valve to be opened to supplement the water; and when it is detected by the water level sensor that the water level in the inner drum reaches the L1, the washing device controls the water inlet valve to be closed. The operation is repeated until the set duration corresponding to the water supplement washing is ended. During the water supplement washing, the washing device may count the number of times of water supplementing the counter, and count the accumulated water supplementing duration by the timer.
At 203, it is determined whether the number of times of water supplementing and the accumulated water supplementing duration are zero; if yes, 204 is performed; and if no, 205 is performed.
At 204, it is determined that the amount of laundry of the washing device is at the R1, and then a washing procedure corresponding to the R1 is executed.
At 205, it is determined whether the number of times of water supplementing is greater than or equal to the c1, and whether the accumulated water supplementing duration is greater than or equal to the t1; if no, 206 is performed; and if yes, 207 is performed.
At 206, it is determined that the amount of laundry of the washing device is at the R2, and then a washing procedure corresponding to the R2 is executed.
At 207, it is determined whether the number of times of water supplementing is greater than or equal to the c2, and whether the accumulated water supplementing duration is greater than or equal to the t2; if no, 208 is performed; and if yes, 209 is performed.
At 208, it is determined that the amount of laundry of the washing device is at the R3, and then a washing procedure corresponding to the R3 is executed.
At 209, it is determined that the amount of laundry of the washing device is at the R4, and then a washing procedure corresponding to the R4 is executed.
Therefore, the method for detecting the amount of laundry of the washing device provided by the embodiments of the disclosure may determine whether the amount of laundry of the washing device is at the R1 based on a result on whether the number of times of water supplementing and the accumulated water supplementing duration during the water supplement washing are zero. In this way, the discrimination between the R1 and the R2 of the washing device and the reliability of detection on the amount of laundry may be improved. Moreover, no additional collection circuit is provided, such that the hardware cost of the washing device is saved.
