[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The technical solution provided by the embodiments of the present disclosure can be applied to clothing processing equipment, which can be a pulsator washing machine, a drum washing machine, a stirring washing machine, a washer-dryer or other types of washing equipment, which are not limited here.

[0044] In the technical solution provided by the embodiment of the present disclosure, the clothing processing equipment includes a water inlet component and a clothing processing barrel; wherein, the water inlet component is connected to the clothing processing barrel, the clothing processing barrel can accommodate a load, the water inlet component feeds water into the clothing processing barrel, and based on this, generates washing water for cleaning the load (such as clothes), thereby achieving washing of the load.

[0045] In the prior art, the water inlet operation of a washing machine is usually performed by determining the water level in multiple water inlet gears based on a motor weighing result. Since there is usually a certain deviation between the motor weighing result and the actual load weight, excessive or insufficient water intake may occur, resulting in a waste of water resources or low washing efficiency.

[0046] The control method, control device, storage medium and clothing processing equipment provided by the embodiments of the present disclosure are exemplarily described below in conjunction with the accompanying drawings.

[0047] For example, Figure 1 A flow chart of a control method provided by an embodiment of the present disclosure. Figure 1 Taking a washing machine as an example, the control method may include the following steps:

[0048] S100, controlling the laundry processing device to perform a water intake operation at a first preset water level.

[0049] Among them, the laundry washing is performed by the washing program of the washing machine, and the washing program may include water inlet operation, washing operation, rinsing operation and dehydration operation, etc. Among them, the water inlet operation is used to control the water inlet component to inject water into the delivery component and / or the laundry treatment barrel, so as to inject the preparations such as detergents in the delivery component and the water required for washing into the laundry treatment barrel. The water inlet operation usually includes two or more preset water inlet levels, such as the first preset water level, the second preset water level and the Nth preset water level, etc., and the two or more preset water levels increase in sequence, such as the second preset water level is greater than the first preset water level, the third preset water level is greater than the second preset water level, the Nth preset water level is greater than the N-1th preset water level, etc. By setting multiple preset water levels, clothes with different loads can be saturated with water, and the washing water can immerse the load to ensure the cleanliness of the laundry. It can be understood that when the load is larger, the more water is required for saturated water absorption, so the water inlet operation should be performed at a higher preset water level.

[0050] In the prior art, a load weighing operation is usually performed before the water inlet operation, that is, a motor or sensor is used to fuzzily weigh the load to obtain an approximate load amount, and then a specific water level is matched as the preset water level for the water inlet operation. Since there may be deviations in the motor weighing or the sensor weighing, the matched preset water level may be inaccurate, resulting in excessive or insufficient water inlet, causing a waste of water resources or insufficient washing, and reducing the user experience.

[0051] To address this technical problem, the embodiment of the present disclosure does not rely on motor or sensor weighing to determine the water inlet level, but first controls the washing machine to perform a water inlet operation at a lower first preset water level, which serves as the basis for subsequent water inlet operations, avoiding the problem of subsequent water inlet level errors caused by pre-weighing deviations.

[0052] In some embodiments, the first preset water level is a minimum water level for water intake operation.

[0053] Specifically, in this embodiment, the minimum water level among the multiple water levels of the washing machine is used as the first preset water level, for example, the first water level among the 8 water levels of a pulsator washing machine or the 3 water levels of a drum washing machine is used as the first preset water level, that is, the water inlet operation starts from the lowest water level of the washing machine. This can avoid the waste of water resources caused by the initial water level being too high when the load is low.

[0054] S102: Determine whether the laundry processing device has reached a first preset water level, and obtain load status information and / or water level fluctuation information.

[0055] Specifically, when the water inlet of the washing machine reaches a first preset water level, the washing machine uses its own sensors or functional components to obtain load status information and / or water level information to determine whether the current water level reaches the optimal washing water level.

[0056] In some embodiments, the load status information includes water content information.

[0057] In this embodiment, the washing machine obtains moisture content information of the clothes through a sensor, for example, obtains conductivity information of the surface of the clothes through a conductivity sensor, so as to determine the moisture content of the clothes.

[0058] In some embodiments, obtaining water level fluctuation information includes: recording first water level information in a clothing processing device at a first moment; controlling load movement in the clothing processing device until a second moment; recording second water level information in the clothing processing device at the second moment; and using a difference or ratio between the first water level information and the second water level information as water level fluctuation information.

[0059] In this embodiment, specifically, the water level information can be obtained indirectly by measuring the water level height in the tub using a distance sensor or an infrared sensor, or by measuring the frequency of the water level using a water level frequency sensor. The fluctuation of the water level is usually caused by the load absorbing water, so in this embodiment, it is necessary to record the first water level information at the first moment and the second water level information at the second moment in sequence, and determine the water level fluctuation information through the water level information at the two moments.

[0060] Here, in order to make the change of water level information fully reflect whether the load is saturated with water, the load movement can be controlled to make the load absorb more water. Among them, different methods can be used to control the load movement based on different washing machines. For example, when the washing machine is a pulsator washing machine, the relative movement between the load and the washing water can be driven by controlling the rotation of the impeller and / or agitator and / or dehydration barrel of the pulsator washing machine for 10 seconds, thereby promoting the load to absorb the washing water; for another example, when the washing machine is a drum washing machine, the relative movement between the load and the washing water can be driven by controlling the rotation of the drum of the drum washing machine for 10 seconds, thereby promoting the load to absorb the washing water. It should be noted that the rotation time of the impeller, agitator, dehydration barrel and / or drum is not specifically limited in this disclosure. Therefore, by promoting the load to further absorb the washing water, the water level fluctuation caused by the load absorbing water is more significant, and the accuracy of the water level fluctuation information is improved.

[0061] When the first water level information and the second water level information before and after the load movement are obtained, the water level fluctuation information can be obtained by obtaining the difference or ratio of the first water level information and the second water level information. The calculation method of the difference or ratio is simple and effective compared to the complex calculation algorithm, and is suitable for application scenarios such as washing machines where the computing power is limited and real-time processing of more data is required.

[0062] S104, determining that the load information and / or the water level fluctuation information meets the preset conditions, and stopping the water inlet operation; otherwise, controlling the clothing processing device to perform the water inlet operation at a second preset water level; wherein the second preset water level is greater than the first preset water level.

[0063] After obtaining the load information and / or water level fluctuation information, by comparing these information with the preset conditions, it is determined whether the current water inflow level is sufficient to make the load saturated with water. If the preset conditions are met, it is considered that the load has achieved saturated water absorption, and the current water level has reached the optimal water level required for washing, and the water inflow operation can be terminated and the washing operation can be started. If the preset conditions are not met, it is considered that the load has not achieved saturated water absorption, and the current water level is less than the water level required to ensure the cleanliness, and is not the optimal water level for washing, so water should be further added to the clothes processing barrel.

[0064] In this embodiment, when it is determined that the current water level has not caused the load to be saturated with water, the washing machine is controlled to fill water into the clothing processing tub at a higher second preset water level, and the load status information and / or water level fluctuation information calculation in step S102 is executed again after the water is filled, so as to execute the judgment on the load saturated with water in step 104 again, and the water filling operation is terminated after the load reaches saturated water absorption.

[0065] In this embodiment, the preset condition can be determined based on the category of the acquired information. For example, when the load status information includes moisture content information, the preset condition includes that the load moisture content is greater than 90%, for example, the load moisture content is 90%, 95%, 100%. This parameter can be set for materials with different water absorption capacities, and the embodiments of the present disclosure do not limit this. For another example, determining that the water level fluctuation information meets the preset condition includes: determining that the water level fluctuation information is less than a first threshold, wherein the first threshold can be determined according to the detection accuracy of different devices and sensors, and the embodiments of the present disclosure do not limit this.

[0066] Therefore, the embodiment of the present disclosure determines whether the clothes are saturated with water by filling water into the clothing treatment barrel at a lower preset water level during the water filling operation, and continues to fill water at a higher water level after the clothes are not saturated with water, until the clothes are saturated with water as the optimal washing water level, thereby avoiding the water level deviation that exists in the prior art that relies on weighing to determine the preset water level, so that the clothing treatment equipment can reduce the use of water resources while ensuring the cleanliness, thereby improving the user experience.

[0067] In some embodiments, the water inlet operation also includes an Nth preset water level, where N is a positive integer greater than or equal to 3; the method also includes: determining that the clothing processing equipment has reached the N-1th preset water level, obtaining load status information and / or water level fluctuation information; determining that the load information and / or water level fluctuation information meets preset conditions, and stopping the water inlet operation; otherwise, controlling the clothing processing equipment to perform the water inlet operation at the Nth preset water level; wherein the Nth preset water level is greater than the N-1th preset water level, and the N-1th preset water level is greater than the second preset water level.

[0068] Among them, the water inlet level includes multiple preset water levels. When determining the water level required for saturated water absorption of clothes, the optimal washing water level is determined by successively injecting washing water of multiple preset water levels, so that the washing machine can determine the optimal water level for more load ranges, providing users with more options for washing.

[0069] In some embodiments, the Nth preset water level is a maximum water level for the water intake operation.

[0070] In this embodiment, for a larger load, water can be added from the minimum water level of the washing machine, such as the 1st level of the pulsator washing machine, until the maximum water level is reached, such as the 8th level of the pulsator washing machine. In this way, the water absorption demand for a larger load can be met, and the water level can be prevented from being too high and exceeding the carrying capacity of the washing machine itself, thereby ensuring the safe use of the washing machine.

[0071] Based on the same inventive concept, an embodiment of the present disclosure also provides a control device for a clothing processing device, which is used to execute the steps of any one of the control methods provided in the above embodiments to achieve corresponding beneficial effects.
