Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and specifically relates to a control method for a washing device and a washing device. Background Art

[0002] "Washing device" refers to a general term for a class of household appliances with washing functions, such as washing machines, washing and drying integrated machines, etc.

[0003] Currently, the washing method of a washing machine is to form a special water flow by the rotation of the agitator or the simultaneous rotation of the agitator and the inner barrel to turn the washing objects, and apply a force to them during the turning process, so that they are repeatedly washed through their own friction and the friction with the agitator and the inner barrel wall to achieve the purpose of being washed clean.

[0004] A washing machine includes a motor that provides power for the rotation of the agitator or the barrel body. In order to improve the washing effect on clothes, some washing machines usually increase the rotation speed or the rotation-stop ratio of the motor. Although this method can improve the washing effect on clothes to a certain extent, during the rotation-stop process of the motor, the clothes cannot be continuously and effectively washed during the pause, resulting in a waste of washing time.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0010] Further, controlling the formation of a non-stop water flow includes: controlling the motor to continuously rotate in the same direction to form a non-stop water flow in the same direction, and / or controlling the motor to rotate continuously with reverse direction changes to form a non-stop water flow with reverse direction changes;

[0011] Preferably, controlling the alternating formation of a non-stop water flow in the same direction and a non-stop water flow with reverse direction changes.

[0012] Further, controlling the formation of a non-stop water flow in the same direction includes: controlling the motor to rotate continuously at a constant speed in the same direction to form a non-stop uniform water flow in the same direction, and / or controlling the motor to rotate continuously with variable speed in the same direction to form a non-stop variable-speed water flow in the same direction.

[0013] Further, controlling the formation of a commutation-free intermittent water flow includes: controlling the commutation of the motor and continuously rotating at a constant speed to form a commutation-uniform and non-intermittent water flow, and / or controlling the commutation of the motor and continuously rotating at a variable speed to form a commutation-pulsed water flow.

[0014] Further, presetting a non-intermittent water flow type corresponding to different load types and / or load weights, obtaining the load type and / or load weight in the current barrel, and controlling the motor to form a non-intermittent water flow corresponding to the obtained load type and / or load weight.

[0015] Further, the load includes a wear-resistant type and a non-wear-resistant type. Judging the type to which the obtained load type belongs. If it belongs to the non-wear-resistant type, then control the motor to form a co-directional non-intermittent water flow. If it belongs to the wear-resistant type, then control the motor to form a commutation non-intermittent water flow or control to alternately form a co-directional non-intermittent water flow and a commutation non-intermittent water flow;

[0016] Preferably, controlling the motor to form a co-directional non-intermittent water flow includes: presetting a dirtiness degree a 0 , obtaining the dirtiness degree a of the load, comparing the obtained dirtiness degree a with the preset dirtiness degree a 0 in terms of magnitude. If a ≥ a 0 , then control to form a co-directional variable-speed non-intermittent water flow;

[0017] Preferably, controlling the motor to form a commutation non-intermittent water flow includes: presetting a dirtiness degree a 0 ', obtaining the dirtiness degree a' of the load, comparing the obtained dirtiness degree a' with the preset dirtiness degree a 0 ', and if a' ≥ a 0 ', then control to form a commutation-pulsed water flow.

[0018] Further, during the washing process, control the motor to first form a co-directional non-intermittent water flow and then form a commutation non-intermittent water flow;

[0019] Preferably, after the non-intermittent water flow is completed and before the washing process is completed, control the motor to form a co-directional non-intermittent water flow.

[0020] Further, the washing device includes a spraying program for spraying water into the barrel of the washing device. When the spraying program runs, control the motor to form a co-directional non-intermittent water flow.

[0021] Further, during the washing process, obtain the state of the load in the barrel. If the load in the barrel is in a floating state, then control to execute the spraying program and control to form a co-directional non-intermittent water flow;

[0022] and / or, preset a foam amount V 0 , obtain the foam amount V in the barrel, compare the obtained foam amount V with the preset foam amount V 0If the size is such that V ≥ V 0 , then control the execution of the spraying program and control the formation of a non-stop water flow in the same direction.

[0024] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0028] The following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings. Description of the Drawings

[0034] It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. Detailed Embodiment

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0036] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The "washing device" refers to the general term for a series of household appliances with functions such as washing, rinsing, and dehydration, such as washing machines, washer-dryers, etc.

[0039] The washing device includes a tub for accommodating clothes, a pulsator rotatably provided in the tub, and a motor for providing power for the rotation of the tub and the pulsator. During the washing process, the motor is controlled to start, providing power for the rotation of the tub and the pulsator, and the rotation of the tub and the pulsator forms a water flow with a certain flow rate to agitate and wash the load.

[0040] The control method of the washing device of the present invention includes: controlling the motor to continuously rotate during the washing process to form an uninterrupted water flow in the tub. The continuous rotation of the motor includes: controlling the motor to run without pause throughout the washing process, which can continuously rotate forward, or continuously rotate backward, or switch to the reverse state without pause after the forward rotation ends.

[0041] Specifically, the formation method of the uninterrupted water flow includes:

[0042] By controlling the continuous rotation of the motor during the washing process, the barrel of the washing device is made to rotate continuously, and there is no pause during the rotation of the barrel, forming a washing water flow that continuously circulates at a certain flow rate and intensity in the barrel. This water flow is the non-intermittent water flow;

[0043] Alternatively, by controlling the continuous rotation of the motor during the washing process, the agitator of the washing device is made to rotate continuously, and there is no pause during the rotation of the agitator. The agitator stirs the water flow and the clothes in the barrel to rotate, forming a washing water flow that continuously circulates at a certain flow rate and intensity in the barrel. This water flow is the non-intermittent water flow.

[0044] Alternatively, by controlling the continuous rotation of the motor during the washing process, the barrel and the agitator of the washing device are made to rotate continuously, forming a washing water flow that continuously circulates at a certain flow rate and intensity in the barrel. Among them, the agitator and the barrel can rotate in the same direction, for example: the agitator and the barrel rotate forward at the same time or reverse at the same time, but their rotation speeds can be the same or different, and can be specifically controlled according to the actual situation; for example: the rotation speed of the agitator is 50 rpm, and the rotation speed of the barrel is 400 rpm; another example: the rotation speed of the agitator is 100 rpm, and the rotation speed of the barrel is 100 rpm; or, the agitator and the barrel can also rotate in opposite directions.

[0045] Furthermore, as Figure 1 shown, the control steps of the control method of the present invention include:

[0046] S1. Start washing;

[0047] S2. Control the motor to rotate continuously during the washing process to form a non-intermittent water flow;

[0048] S3. Detect whether the cumulative washing duration has reached the preset washing duration; if so, execute step S4; otherwise, return to step S2;

[0049] S4. Washing is completed;

[0050] Among them, the preset washing duration in step S3 is related to the circulation intensity of the formed non-intermittent water flow, the degree of dirt of the load, and the weight of the load; the stronger the circulation intensity of the non-intermittent water flow, the shorter the corresponding preset washing duration; the higher the degree of dirt of the load, the longer the corresponding preset washing duration; the heavier the weight of the load, the longer the corresponding preset washing duration.

[0051] In the present invention, the motor rotates continuously during the washing process, so that a non-intermittent continuous circulation water flow can be formed throughout the washing process, maintaining the dynamic nature of the water flow. The non-intermittent water flow continuously flushes the load in the form of a certain flow rate, which not only helps to better dissolve and remove stains, but also improves the cleaning efficiency, ensuring that the washed load is cleaner and fresher.

[0052] During the entire washing process of the present invention, there is no idle period, and the clothes are constantly in a state of being flushed, which improves the washing efficiency and shortens the washing duration. Moreover, the continuous rotation of the motor reduces the energy consumption generated by frequent start-up and stop compared with the traditional intermittent rotation.

[0053] As an embodiment of the present invention, controlling the formation of non-intermittent water flow includes: controlling the motor to continuously rotate in the same direction during the washing process to form a non-intermittent water flow in the same direction, that is, controlling the motor to continuously rotate forward or continuously rotate backward during the washing process, and forming a continuously forward-flowing or continuously backward-flowing water flow in the barrel, that is, a non-intermittent water flow in the same direction.

[0054] The non-intermittent water flow in the same direction can flush and wash the load along the same direction. This kind of water flow has less wear on the load and will not cause the load to be entangled to a large extent. Especially for fabrics such as silk and plush, it has a good washing effect.

[0055] Or, controlling the motor to rotate continuously with commutation during the washing process to form a non-intermittent water flow with commutation, that is, controlling the motor to switch to the reverse state without pause after the forward rotation ends during the washing process, forming a forward-flowing water flow and a backward-flowing water flow in the barrel, and the forward-flowing water flow and the backward-flowing water flow switch without pause, that is, a non-intermittent water flow with commutation.

[0056] Among them, the method to realize the motor switching to the reverse state without pause after the forward rotation ends includes: the motor has two power supply processes of forward power supply and reverse power supply. After the forward power supply ends, the motor continues to rotate forward under the action of its own inertia, and the reverse power supply is turned on during the inertial forward rotation process of the motor, so that the motor can switch to the reverse state without pause after the forward rotation ends.

[0057] The non-intermittent water flow with commutation can flush and wash the load along the forward and reverse two directions, so that the load can be washed more fully and comprehensively. Especially for clothes with small volume, not easy to entangle and high dirt degree, adopting the non-intermittent water flow with commutation can greatly improve the washing effect.

[0058] As a preferred solution, during the entire washing process, the non-intermittent water flow in the same direction and the non-intermittent water flow with commutation can be controlled to be alternately formed. In this way, it can not only appropriately reduce the wear degree on the load, but also improve the washing effect on the load.

[0059] As an implementation manner of this embodiment, controlling the formation of the non-intermittent water flow in the same direction includes:

[0060] Controlling the motor to rotate continuously, at a constant speed and in the same direction during the washing process to form a non-intermittent uniform water flow in the same direction. That is, during the continuous rotation of the motor in the same direction, the rotational speed remains constant, and a water flow that rotates in the same direction and at a uniform speed is formed in the barrel, that is, a non-intermittent uniform water flow in the same direction.

[0061] The impact of a unidirectional, uniform, and non-stop water flow on the load is relatively small, and it is not easy to cause wear and tear on the clothes, so it can be used to wash fabrics with low abrasion resistance. In this embodiment, the washing intensity can be directly adjusted by controlling the motor speed, and then the washing duration can be adjusted according to the washing intensity. The control method is simple and easy to implement.

[0062] Alternatively, control the motor to rotate continuously in the same direction and at a variable speed during the washing process to form a unidirectional variable-speed non-stop water flow. That is, during the continuous rotation of the motor in the same direction, the speed is in a changing state, and a water flow that rotates in the same direction and at a variable speed is formed in the barrel. This water flow has a strong and weak acting force on the clothes, and can knead the clothes in one direction, achieving a good cleaning effect on the stains on the load.

[0063] As another embodiment of this example, controlling the formation of a reversing non-stop water flow includes:

[0064] Control the motor to rotate continuously in reverse and at a constant speed during the washing process to form a reversing uniform non-stop water flow. That is, during the continuous reverse rotation of the motor, the speed remains constant, and a water flow that rotates in reverse and at a uniform speed is formed in the barrel, that is, a reversing uniform non-stop water flow.

[0065] Among them, to control the motor to rotate continuously in reverse and at a constant speed during the washing process, it is necessary to accurately control the forward power supply timing and reverse power supply timing of the motor; for example: control the end of the forward power supply, and before the forward rotation stops, control the reverse power supply to turn on, and switch the forward speed to the reverse speed; preferably, before the end of the forward power supply, first briefly accelerate forward and then the forward speed briefly rises, while controlling the reverse power supply to turn on, switch the forward speed to the reverse speed, and the forward speed and the reverse speed are equal in magnitude.

[0066] The reversing uniform non-stop water flow can perform uniform and all-round washing on the clothes. The washing process is gentle and uniform, and it will not cause large impact wear on the clothes, nor will it cause large deformation of the clothes.

[0067] Or, control the motor to rotate continuously in reverse and at a variable speed during the washing process to form a reversing pulse water flow. That is, during the continuous reverse rotation of the motor, the speed is variable, and a water flow that rotates in reverse and at a variable speed is formed in the barrel, that is, a reversing pulse water flow. The reversing pulse water flow can not only wash the clothes in different directions, but also, due to the variable speed, the formed water flow has a kneading effect on the clothes in different directions, and the cleaning effect is good.

[0068] As an embodiment of the present invention, preset non-stop water flow types corresponding to different load types, obtain the type of the load in the current barrel, and control the motor to form a non-stop water flow corresponding to the obtained load type. Among them, different load types include: loads of different materials, loads of different degrees of dirt, and loads of different wearing types.

[0069] Specifically, as Figure 2 shown, the control steps include:

[0070] S1. Start washing;

[0071] S2. Obtain the type of the load in the current barrel;

[0072] S3. Control the motor to form a non-stop water flow corresponding to the obtained load type;

[0073] S4. Detect whether the cumulative washing duration has reached the preset washing duration. If so, execute step S5; otherwise, return to step S3;

[0074] S5. Washing is completed;

[0075] In this embodiment, different non-stop water flow types corresponding to different loads are pre-stored in the washing device, and the motor rotation is directly controlled according to the obtained load type to form the corresponding non-stop water flow type.

[0076] In this embodiment, if the obtained load type includes multiple types, then according to the proportion of different types of loads, select to form the non-stop water flow corresponding to the load with the largest proportion. In this way, it is ensured that most of the clothes in the barrel are washed cleanly first.

[0077] Or, sort according to the degree of dirt of different types of loads from large to small, first control to form the non-stop water flow corresponding to the load with a larger degree of dirt, and then form the non-stop water flow corresponding to the load with a smaller degree of dirt; in this way, different loads can be washed cleanly according to their respective needs during the entire washing process.

[0078] As an implementation manner of this embodiment, the load includes wear-resistant type and non-wear-resistant type. Determine the type to which the obtained load belongs. If it belongs to the non-wear-resistant type, control the motor to form a unidirectional non-stop water flow. If it belongs to the wear-resistant type, control the motor to form a reversing non-stop water flow or control to alternately form a unidirectional non-stop water flow and a reversing non-stop water flow.

[0079] Among them, determining the type to which the obtained load belongs includes: identifying the label on the load. The label usually provides information about the load material composition and washing instructions, such as denim is of the wear-resistant type. Or, the washing device can be connected to a smart device or a smart home system. By communicating with a smartphone or other smart devices, the user can select the load type through an application and send the selected load type to the washing device. Specifically, as Figure 3 shown, the control steps include

[0080] S1. Start washing;

[0081] S2. Obtain the load type in the current barrel;

[0082] S3. If the obtained load type belongs to type A, execute step S4;

[0083] If the obtained load type belongs to type B, execute step S6;

[0084] Among them, type A and type B represent different loads, and their specific meanings can be defined artificially by the user. For example, type A loads are not easily worn and wrinkled under the impact washing of strong water flow; while type B loads are easily worn and wrinkled under the impact washing of strong water flow; another example: type A loads have higher requirements for washing cleanliness; while type B loads have moderate or low requirements for washing cleanliness;

[0085] For example, type A is wear-resistant loads (such as acrylic, spandex, denim); type B is non-wear-resistant loads (such as knitted wool); or, type A is clothes that are not easily wrinkled (such as clothes made of polyester and nylon), type B is clothes that are easily wrinkled (such as clothes made of silk, cotton and linen); or, type A is children's clothes, type B is adult's clothes;

[0086] S4. Control the motor to form a non-stop reversing water flow; and execute step S5;

[0087] S5. Detect whether the cumulative washing duration has reached the preset washing duration t 1 ; if so, execute step S8; if not, return to step S4;

[0088] S6. Control the motor to form a non-stop unidirectional water flow;

[0089] S7. Detect whether the cumulative washing duration has reached the preset washing duration t 2 , if so, execute step S8; if not, return to step S6;

[0090] S8. The washing is completed.

[0091] Among them, the preset washing duration t 2 and the preset washing duration t 1 are adjustable. Preferably, the preset washing duration t 2 is greater than the preset washing duration t 1 .

[0092] In this embodiment, if the clothes are non-wear-resistant, control the motor to form a non-stop unidirectional water flow. The non-stop unidirectional water flow has a low wear degree on the clothes and will not cause a large degree of entanglement of the load. While washing the clothes, the wear on the clothes is minimized to the greatest extent and the clothes wrinkles are reduced.

[0093] If the clothing is of wear-resistant type, control the motor to form a non-stop reversing water flow, which can wash the load along two directions, forward and reverse, so that the load can be washed more fully and comprehensively, and the washing efficiency and the cleaning degree of the clothing are relatively high.

[0094] Further, controlling the motor to form a non-stop unidirectional water flow includes: presetting a dirtiness degree a 0 , obtaining the dirtiness degree a of the load, and comparing the obtained dirtiness degree a with the preset dirtiness degree a 0 . If a≥a 0 , then control to form a non-stop unidirectional variable-speed water flow.

[0095] Specifically, as Figure 4 shown, the control steps include:

[0096] S1. Start washing;

[0097] S2. Obtain the type of the load in the current barrel;

[0098] S3. Determine whether the obtained load belongs to type A; if yes, execute step S4; otherwise execute step S6;

[0099] S4. Control the motor to form a non-stop reversing water flow;

[0100] S5. Detect whether the cumulative washing duration has reached the preset washing duration t 1 . If yes, execute step S11; otherwise return to step S4;

[0101] S6. Obtain the dirtiness degree a of the load;

[0102] S7. Determine whether the obtained dirtiness degree a is greater than or equal to the preset dirtiness degree a 0 . If yes, execute step S8; otherwise return to step S9;

[0103] S8. Control to form a non-stop unidirectional variable-speed water flow;

[0104] S9. Control to form a non-stop unidirectional constant-speed water flow;

[0105] S10. Detect whether the cumulative washing duration has reached the preset washing duration t 2 . If yes, execute step S11; otherwise return to step S7;

[0106] S11. Washing completed.

[0107] Among them, step S6, obtaining the dirtiness degree a of the load, includes the following methods:

[0108] Method 1: Install a turbidity sensor in the washing device, such as an optical sensor, an electrochemical sensor, or other pollutant sensors, to detect the concentration of pollutants in the washing water. These sensors can measure characteristics such as the color, turbidity, and conductivity of the water, thereby evaluating the dirtiness of the load.

[0109] Method 2: Utilize an electronic nose sensor array, which can simulate the human olfactory system. The electronic nose sensor array is used to identify the odor in the washing water, and then evaluate the dirtiness of the load.

[0110] Method 3: Use intelligent algorithms and machine learning techniques to infer the dirtiness of the load by monitoring the water quality changes during the washing process.

[0111] Method 4: Use a camera to capture images in the water during the washing process, and then use image processing techniques to analyze characteristics such as the color and particulate matter in the water, thereby determining the dirtiness of the load.

[0112] In this embodiment, if the obtained dirtiness degree a is greater than or equal to the preset dirtiness degree a 0 , it indicates that the current non-abrasive load has a high dirtiness degree. At this time, control the formation of a co-directional variable-speed non-stop water flow, that is, form a co-directional and variable-speed flowing water flow in the barrel. This water flow has a strong and weak acting force on the clothes, can rub the clothes in one direction, has a good cleaning effect on the stains on the clothes, and minimizes the generation of clothes wrinkles.

[0113] In this embodiment, controlling the motor to form a reversing non-stop water flow includes: presetting the dirtiness degree a 0 ', obtaining the dirtiness degree a' of the load, comparing the obtained dirtiness degree a' with the preset dirtiness degree a 0 ', if a' ≥ a 0 ', then control the formation of a reversing pulsed water flow.

[0114] If the obtained dirtiness degree a is greater than or equal to the preset dirtiness degree a 0 , it indicates that the current clothes are of the wear-resistant type and have a high dirtiness degree. At this time, control the formation of a reversing pulsed water flow. The pulsed water flow can not only wash the clothes in different directions, but also, due to the variable rotation speed, the formed water flow has a rubbing effect on the clothes in different directions, and the cleaning effect is better.

[0115] As an embodiment of the present invention, during the washing process, control the motor to first form a co-directional non-stop water flow, and then form a reversing non-stop water flow. At the beginning of the washing, it is first necessary to ensure that the clothes can be wetted by the water flow. At this time, control the formation of a co-directional non-stop water flow to reduce the wear on the clothes during the wetting process; after the clothes are wetted, the clothes need to be washed. At this time, control the formation of a reversing non-stop water flow to ensure a better cleaning effect on the clothes.

[0116] Preferably, after the completion of the non-intermittent water flow in the reverse direction and before the completion of the washing process, the motor is controlled to form a non-intermittent water flow in the same direction; after the completion of the non-intermittent water flow in the reverse direction, the clothes are basically washed clean. At this time, controlling the formation of a non-intermittent water flow in the same direction enables the clothes to be evenly distributed along one direction, preparing for subsequent rinsing and dehydration.

[0117] As another embodiment of the present invention, the washing device includes a spraying program for spraying water into the barrel of the washing device. When the spraying program runs, the motor is controlled to form a non-intermittent water flow in the same direction.

[0118] In this embodiment, during the flow of the non-intermittent water flow in the same direction, the clothes can be driven to rotate along the same direction. In this way, when the spraying program is started, the sprayed water can be evenly sprayed on the clothes, comprehensively spraying and flushing the clothes.

[0119] As an implementation manner of this embodiment, during the washing process, the state of the load in the barrel is obtained. If the load in the barrel is in a floating state, the spraying program is controlled to be executed, and a non-intermittent water flow in the same direction is controlled to be formed. Specifically, a camera is provided in the washing device of the present invention for collecting images in the barrel, and it is determined whether the load is in a floating state according to the collected images.

[0120] In this implementation manner, if the clothes are in a floating state, the clothes cannot be washed effectively. At this time, the spraying program is controlled to be executed, and the floating clothes are flushed into the washing water by the sprayed water. At the same time, a non-intermittent water flow in the same direction is controlled to ensure that the sprayed water can comprehensively spray on the floating clothes, and then all the floating clothes are flushed below the liquid level.

[0121] As another implementation manner of this embodiment, a preset foam amount V 0 is set, the foam amount V in the barrel is obtained, and the obtained foam amount V is compared with the preset foam amount V 0 . If V≥V 0 , the spraying program is controlled to be executed, and a non-intermittent water flow in the same direction is controlled to be formed. When the spraying program is executed, the drainage program can be synchronously controlled to be started; if V<V 0 , the spraying program is not executed.

[0122] In this implementation manner, the method for obtaining the foam amount V in the barrel includes the following:

[0123] Method 1: A camera is provided in the washing device for collecting images in the barrel, and the foam amount V in the barrel is obtained according to the collected images.

[0124] Method 2: An ultrasonic sensor is provided in the washing device. The ultrasonic sensor can be used to monitor the foam in the liquid. Specifically, foam usually has relatively special acoustic characteristics, and its ability to reflect and absorb ultrasonic waves is different from that of water. By studying the difference in the reflection characteristics between foam and water, the presence and amount of foam can be identified and estimated.

[0125] In this embodiment, if the obtained foam volume V is greater than or equal to the preset foam volume V 0 , it indicates that there is a large amount of foam in the current barrel. At this time, it is necessary to control the execution of the spraying program, and the spraying water will wash out the foam. During this period, a co-directional and non-stop water flow is controlled to ensure that the spraying water can be evenly and comprehensively sprayed into the barrel, improving the washing effect on the foam.

[0126] The present invention also provides a washing device, which is controlled by the control method described in any of the above technical solutions. The washing device includes a barrel for accommodating clothes, a wave wheel rotatably arranged in the barrel, and a motor for providing power for the rotation of the barrel and the wave wheel.

[0127] The motor of the washing device can continuously rotate during the washing process, forming a non-stop water flow in the barrel of the washing device. The non-stop water flow continuously circulates without interruption or pause.

[0128] The continuously rotating motor can ensure that the washing water is evenly distributed throughout the barrel. This helps to ensure that the washing water fully wets the load, improving the washing effect. The continuous rotation of the motor helps to reduce the friction between the loads, thereby reducing the possibility of load entanglement and knotting, which helps to extend the service life of the load and reduce losses. In addition, the continuously rotating motor makes the washing water more active, increasing the flushing effect of the washing water on the clothes, helping to more effectively remove stains, dust and bacteria, and improving the washing efficiency.

[0129] Particularly, the continuous rotation of the motor can shorten the washing cycle because during the rotation process, the washing water can contact the clothes more quickly, which means that the washing time can be shortened, thus improving the working efficiency of the washing device.

[0130] The above are only preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the above-mentioned disclosed technical content into equivalent embodiments with equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
