Description

Control method of washing equipment and washing equipment Technical Field

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

[0002] "Washing equipment" refers to a general term for a type of household appliances with washing functions, such as washing machines, washer-dryers, etc.

[0003] At present, the washing method of a washing machine is to turn the laundry over by a special water flow formed by the rotation of the impeller or the simultaneous rotation of the impeller and the inner tub, and exert force on it during the turning process, so that it is repeatedly washed through its own friction and the friction with the impeller and the inner tub wall to achieve the purpose of cleaning.

[0004] Washing machines include a motor that powers the impeller or drum. To improve cleaning performance, some washing machines increase the motor's speed or the run-to-stop ratio. While this approach improves cleaning performance to a certain extent, the motor's pauses prevent continuous and effective washing, resulting in wasted washing time.

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

[0006] Summary of the Invention

[0007] The present invention provides a control method for a washing device, so as to achieve the purpose of improving the washing efficiency of the washing device, shortening the washing time, and simplifying the control flow of the washing process.

[0008] The present invention also provides a washing device to achieve the purpose of washing clothes efficiently and improving the cleaning effect.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] A control method for a washing device includes a motor for providing power for the rotation of a barrel and / or a pulsator, and the motor is controlled to rotate continuously during the washing process to form an uninterrupted water flow in the barrel.

[0011] Furthermore, controlling to form a non-intermittent water flow includes: controlling the motor to continuously rotate in the same direction to form a non-intermittent water flow in the same direction, and / or controlling the motor to continuously rotate in a reverse direction to form a non-intermittent water flow in a reverse direction;

[0012] Preferably, the control is to alternately form a same-direction non-intermittent water flow and a reversed non-intermittent water flow.

[0013] Furthermore, controlling to form a non-intermittent water flow in the same direction includes: controlling the motor to continuously rotate in the same direction and at a constant speed to form a non-intermittent water flow in the same direction at a uniform speed, and / or controlling the motor to continuously rotate in the same direction and at a variable speed to form a non-intermittent water flow in the same direction at a variable speed.

[0014] Furthermore, controlling to form a reversing non-intermittent water flow includes: controlling the motor to reversing and continuously rotating at a constant speed to form a reversing uniform speed non-intermittent water flow, and / or controlling the motor to reversing and continuously rotating at a variable speed to form a reversing pulsed water flow.

[0015] Furthermore, the non-intermittent water flow type corresponding to different load types and / or load weights is preset, the load type and / or load weight in the current barrel is obtained, and the motor is controlled to form a non-intermittent water flow corresponding to the obtained load type and / or load weight.

[0016] Furthermore, the load includes a wear-resistant type and a non-wear-resistant type. The type of the load is determined. If the load is non-wear-resistant, the motor is controlled to form a unidirectional non-intermittent water flow. If the load is wear-resistant, the motor is controlled to form a reversing non-intermittent water flow or to alternately form a unidirectional non-intermittent water flow and a reversing non-intermittent water flow.

[0017] Preferably, controlling the motor to form a non-intermittent water flow in the same direction includes: presetting a dirtiness degree a0, obtaining a dirtiness degree a of the load, comparing the obtained dirtiness degree a with the preset dirtiness degree a0, and if a≥a0, controlling to form a non-intermittent water flow at a variable speed in the same direction;

[0018] Preferably, controlling the motor to form a reversing non-intermittent water flow includes: presetting the dirtiness a0', obtaining the dirtiness a' of the load, comparing the obtained dirtiness a' with the preset dirtiness a0', and if a'≥a0', controlling to form a reversing pulse water flow.

[0019] Furthermore, during the washing process, the motor is controlled to first form a non-intermittent water flow in the same direction, and then form a non-intermittent water flow in a reverse direction;

[0020] Preferably, after the non-intermittent water flow is completed and before the washing process is completed, the motor is controlled to form a non-intermittent water flow in the same direction.

[0021] Furthermore, the washing device includes a spraying program for spraying water into the barrel of the washing device. When the spraying program is running, the motor is controlled to form a non-intermittent water flow in the same direction.

[0022] Furthermore, during the washing process, the state of the load in the barrel is obtained, and if the load in the barrel is in a floating state, the spraying program is controlled to be executed, and the same-direction non-intermittent water flow is controlled to be formed;

[0023] And / or, preset the foam amount V0, obtain the foam amount V in the barrel, compare the obtained foam amount V with the preset foam amount V0, if V≥V0, control the execution of the spray program, and control the formation of uninterrupted water flow in the same direction.

[0024] The present invention also provides a washing device controlled by any control method described in the above technical solutions.

[0025] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0026] In the present invention, the motor rotates continuously during the washing process, so that an uninterrupted and continuous flow of water can be formed throughout the washing process, maintaining the dynamic nature of the water flow. The uninterrupted 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 load is fresher and cleaner after washing.

[0027] The present invention does not have an idle period during the entire washing process, and the clothes are always in a flushing state, which improves the washing efficiency and shortens the washing time; and the continuous rotation of the motor reduces the energy consumption caused by frequent starting and stopping compared to traditional intermittent rotation.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below 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.

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] "Washing equipment" refers to a general term for a series of household appliances with functions such as washing, rinsing, and dehydration, such as washing machines, washer-dryers, etc.

[0040] A washing machine includes a tub for holding clothes, a pulsator rotatably mounted within the tub, and a motor that powers the tub and pulsator. During the wash cycle, the motor is controlled to power the tub and pulsator, which rotate to create a water flow at a constant velocity, turning and washing the load.

[0041] The control method of the washing machine 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 operate continuously throughout the washing process, and the motor may rotate continuously forward, continuously reverse, or switch to a reverse state without interruption after completing forward rotation.

[0042] Specifically, the formation of uninterrupted water flow includes:

[0043] By controlling the motor to rotate continuously during the washing process, the drum of the washing equipment rotates continuously without any pauses, forming a washing water flow that flows continuously at a certain flow rate and intensity in the drum. This water flow is called non-intermittent water flow.

[0044] Alternatively, by controlling the motor to rotate continuously during the washing process, the impeller of the washing equipment will continue to rotate without any pause. The impeller stirs the water flow in the barrel and the clothes rotate, forming a washing water flow in the barrel that flows continuously at a certain flow rate and intensity. This water flow is called uninterrupted water flow.

[0045] Alternatively, by controlling the motor to continuously rotate during the washing process, the drum and impeller of the washing apparatus can continuously rotate, forming a wash water flow within the drum at a constant flow rate and intensity. The impeller and drum can rotate in the same direction, e.g., they can rotate simultaneously forward or reverse, but their speeds can be the same or different, depending on the actual situation. For example, the impeller can rotate at 50 rpm and the drum at 400 rpm; another example is the impeller can rotate at 100 rpm and the drum at 100 rpm. Alternatively, the impeller and drum can rotate in opposite directions.

[0046] Furthermore, as shown in FIG1 , the control steps of the control method of the present invention include:

[0047] S1, start washing;

[0048] S2, controlling the motor to continuously rotate during the washing process to form an uninterrupted water flow;

[0049] S3, check whether the accumulated washing time reaches the preset washing time; if so, execute step S4; otherwise, return to step S2;

[0050] S4, washing is completed;

[0051] Among them, the preset washing time in step S3 is related to the flow intensity of the uninterrupted water flow, the degree of dirtiness of the load, and the weight of the load; the stronger the flow intensity of the uninterrupted water flow, the shorter the corresponding preset washing time; the higher the degree of dirtiness of the load, the longer the corresponding preset washing time; the heavier the weight of the load, the longer the corresponding preset washing time.

[0052] In the present invention, the motor rotates continuously during the washing process, so that an uninterrupted and continuous flow of water can be formed throughout the washing process, maintaining the dynamic nature of the water flow. The uninterrupted 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 load is fresher and cleaner after washing.

[0053] The present invention does not have an idle period during the entire washing process, and the clothes are always in a flushing state, which improves the washing efficiency and shortens the washing time; and the continuous rotation of the motor reduces the energy consumption caused by frequent starting and stopping compared to traditional intermittent rotation.

[0054] 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 reverse during the washing process to form a water flow that continuously flows forward or continuously flows in the reverse direction in the barrel body, that is, a non-intermittent water flow in the same direction.

[0055] The uninterrupted water flow in the same direction can flush and wash the load in the same direction. This kind of water flow causes less wear on the load and will not cause the load to be entangled to a large extent. It has a better washing effect especially for fabrics such as silk and plush.

[0056] Alternatively, the motor is controlled to reverse and rotate continuously during the washing process to form a reversing uninterrupted water flow; that is, the motor is controlled to switch to the reverse state without pause after the forward rotation is completed during the washing process, forming a forward flowing water flow and a reverse flowing water flow in the barrel body, and the forward flowing water flow and the reverse flowing water flow are switched without pause, that is, a reversing uninterrupted water flow.

[0057] Among them, the method of realizing that the motor switches to the reverse state without stopping after the forward rotation ends includes: the motor has two power supply processes, 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 its inertia forward rotation process, so that the motor can switch to the reverse state without stopping after the forward rotation ends.

[0058] The reversing non-intermittent water flow can flush and wash the load in both forward and reverse directions, so that the load can be washed more fully and comprehensively; especially for clothes that are small in size, not easy to tangle and highly dirty, the use of reversing non-intermittent water flow can greatly improve the cleaning effect.

[0059] As a preferred solution, during the entire washing process, the water flow can be controlled to alternately flow in the same direction without interruption and in a reversed direction without interruption, which can not only appropriately reduce the wear on the load but also improve the cleaning effect on the load.

[0060] As an implementation method of this embodiment, controlling and forming a non-intermittent water flow in the same direction includes:

[0061] The motor is controlled to rotate continuously in the same direction and at a constant speed during the washing process, forming a uniform and uninterrupted water flow in the same direction. That is, the motor rotates continuously in the same direction, and the speed remains constant, forming a uniform and uninterrupted water flow in the tub.

[0062] The uniform, uninterrupted flow of water in the same direction has a minimal impact on the load, is less likely to cause wear and tear on clothing, and can be used to wash fabrics with low wear resistance. In this embodiment, the washing intensity can be directly adjusted by controlling the motor speed, and the washing time can be adjusted accordingly. The control method is simple and easy to implement.

[0063] Alternatively, the motor can be controlled to continuously rotate in the same direction at variable speeds during the washing process, creating a continuous, variable-speed water flow in the same direction. That is, while the motor continuously rotates in the same direction, its speed varies, creating a water flow in the same direction at variable speeds within the drum. This water flow exerts a varying force on the clothes, kneading them in one direction and effectively cleaning the stains on the load.

[0064] As another implementation of this embodiment, controlling the formation of reversing non-intermittent water flow includes:

[0065] The motor is controlled to reverse direction and rotate continuously at a constant speed during the washing process, forming a reversing, uniform and uninterrupted water flow. That is, during the reversing and continuous rotation process, the motor speed remains constant, forming a reversing, uniform and uninterrupted water flow in the tub.

[0066] Among them, to control the motor to reverse and rotate continuously 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 start, and switch the forward speed to the reverse speed; preferably, before the end of the forward power supply, first briefly accelerate forward and then briefly increase the forward speed, and at the same time control the reverse power supply to start, switch the forward speed to the reverse speed, and the forward speed and the reverse speed are equal.

[0067] The reversing, uniform and uninterrupted water flow can wash the clothes evenly in all directions. The washing process is gentle and uniform, and will not cause great impact and wear to the clothes, nor will it cause great deformation of the clothes.

[0068] Alternatively, the motor can be controlled to reverse direction and continuously rotate at variable speeds during the wash cycle, creating a reversing pulsed water flow. Specifically, the motor's speed can be varied during the reversing and continuous rotation process, creating a reversing, variable-speed water flow within the drum, known as a reversing pulsed water flow. This reversing pulsed water flow not only rinses the clothes in different directions, but also, due to the variable speed, creates a kneading effect on the clothes in different directions, resulting in a better cleaning effect.

[0069] In one embodiment of the present invention, a continuous water flow type corresponding to different load types is preset, the type of load currently in the tub is obtained, and the motor is controlled to generate a continuous water flow corresponding to the obtained load type. The different load types include loads of different materials, loads of different degrees of dirtiness, and loads of different clothing types.

[0070] Specifically, as shown in FIG2 , the control steps include:

[0071] S1, start washing;

[0072] S2. Get the type of load in the current bucket;

[0073] S3, controlling the motor to form a non-intermittent water flow corresponding to the acquired load type;

[0074] S4, detecting whether the accumulated washing time reaches the preset washing time, if so, executing step S5, otherwise returning to step S3;

[0075] S5, washing is completed;

[0076] In this embodiment, the non-intermittent water flow types corresponding to different loads are pre-stored in the washing device, and the motor is directly controlled to rotate according to the acquired load type to form the corresponding non-intermittent water flow type.

[0077] In this embodiment, if the load types obtained include multiple types, then according to the proportions of the different types of loads, the uninterrupted water flow corresponding to the load with the largest proportion is selected to form. In this way, it is prioritized to ensure that most of the clothes in the barrel are washed clean.

[0078] Alternatively, different types of loads are sorted from most to least dirty according to their degree of dirtiness, and the uninterrupted water flow corresponding to the loads with greater dirtiness is controlled first, and then the uninterrupted water flow corresponding to the loads with less dirtiness is controlled; in this way, different loads can be cleaned separately according to their respective needs during the entire washing process.

[0079] As an implementation method of this embodiment, the load includes a wear-resistant type and a non-wear-resistant type. The type of the acquired load is determined. If it is a non-wear-resistant type, the motor is controlled to form a non-intermittent water flow in the same direction. If it is a wear-resistant type, the motor is controlled to form a reversing non-intermittent water flow or to control the alternation of forming a non-intermittent water flow in the same direction and a reversing non-intermittent water flow.

[0080] Determining the type of the acquired load includes: identifying a label on the load, which generally provides information about the material composition of the load and washing instructions, such as whether denim is wear-resistant. Alternatively, the washing device can be connected to a smart device or smart home system. By communicating with a smartphone or other smart device, the user can select the type of load through an application and send the selected load type to the washing device. Specifically, as shown in FIG3 , the control steps include:

[0081] S1, start washing;

[0082] S2. Get the load type in the current bucket;

[0083] S3. If the acquired load type belongs to type A, execute step S4;

[0084] If the acquired load type belongs to type B, execute step S6;

[0085] Type A and Type B represent different loads, and their specific meanings can be defined by the user. For example, a Type A load is less susceptible to wear and wrinkles under the impact of a strong water flow, while a Type B load is more susceptible to wear and wrinkles under the impact of a strong water flow. Another example is that a Type A load has higher requirements for the cleanliness of washing, while a Type B load has moderate or low requirements for the cleanliness of washing.

[0086] For example, Type A is wear-resistant loads (such as acrylic, spandex, and denim); Type B is non-wear-resistant loads (such as knitted wool); or, Type A is wrinkle-resistant clothing (such as polyester and nylon clothing), and Type B is wrinkle-prone clothing (such as silk and cotton and linen clothing); or, Type A is children's clothing, and Type B is adult clothing.

[0087] S4, control the motor to form a reversing non-intermittent water flow; and execute step S5;

[0088] S5, check whether the accumulated washing time reaches the preset washing time t1; if so, execute step S8; if not, return to step S4;

[0089] S6, control the motor to form a non-intermittent water flow in the same direction;

[0090] S7, check whether the accumulated washing time reaches the preset washing time t2, if so, go to step S8; if not, return to step S6;

[0091] S8. Washing is completed.

[0092] The preset washing time t2 and the preset washing time t1 are adjustable, and preferably the preset washing time t2 is greater than the preset washing time t1.

[0093] In this embodiment, if the clothes are non-wear-resistant, the motor is controlled to form a non-intermittent water flow in the same direction. The non-intermittent water flow in the same direction has low wear on the clothes and will not cause the load to be entangled to a large extent. While washing the clothes, the wear on the clothes is minimized to the greatest extent and wrinkles on the clothes are reduced.

[0094] If the clothes are wear-resistant, the motor is controlled to form a reversing uninterrupted water flow. The reversing uninterrupted water flow can flush and wash the load in both positive and reverse directions, so that the load can be washed more fully and comprehensively, and the washing efficiency and the degree of cleaning of the clothes are higher.

[0095] Furthermore, controlling the motor to form a same-direction non-intermittent water flow includes: presetting a dirtiness a0, obtaining a dirtiness a of the load, comparing the obtained dirtiness a with the preset dirtiness a0, and if a≥a0, controlling to form a same-direction variable-speed non-intermittent water flow.

[0096] Specifically, as shown in FIG4 , the control steps include:

[0097] S1, start washing;

[0098] S2. Get the type of load in the current bucket;

[0099] S3. Determine whether the acquired load belongs to type A; if so, execute step S4; otherwise, execute step S6;

[0100] S4, control the motor to form reversing non-intermittent water flow;

[0101] S5, checking whether the accumulated washing time reaches the preset washing time t1, if so, executing step S11, otherwise returning to step S4;

[0102] S6. Obtain the dirtiness a of the load;

[0103] S7, determining whether the obtained dirtiness a is greater than or equal to the preset dirtiness a0, if so, executing step S8, otherwise returning to step S9;

[0104] S8, control to form a non-intermittent water flow with variable speed in the same direction;

[0105] S9, control to form uniform and uninterrupted water flow in the same direction;

[0106] S10, detecting whether the accumulated washing time reaches the preset washing time t2, if so, executing step S11, otherwise returning to step S7;

[0107] S11, washing is completed.

[0108] Step S6, obtaining the dirtiness a of the load, includes the following methods:

[0109] Method 1: Install a turbidity sensor in the washing equipment, such as an optical sensor, electrochemical sensor, or other pollutant sensor, to detect the concentration of pollutants in the wash water. These sensors can measure characteristics such as color, turbidity, and conductivity in the water to assess the dirtiness of the load.

[0110] Method 2: Using 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 wash water and then assess the dirtiness of the load.

[0111] Method 3: Use intelligent algorithms and machine learning technology to infer the dirtiness of the load by monitoring changes in water quality during the washing process.

[0112] Method 4: Use a camera to capture images in the water during the washing process, and then use image processing technology to analyze the color, particles and other characteristics of the water to determine the dirtiness of the load.

[0113] In this embodiment, if the obtained dirtiness a is greater than or equal to the preset dirtiness a0, it indicates that the current non-wear-resistant load has a high dirtiness. At this time, the control is to form a same-direction variable-speed uninterrupted water flow, that is, a same-direction, variable-speed water flow is formed in the barrel. This water flow has a sometimes strong and sometimes weak force on the clothes, can knead the clothes in one direction, has a better cleaning effect on the stains on the clothes, and minimizes the generation of wrinkles on the clothes.

[0114] In this embodiment, controlling the motor to form a reversing non-intermittent water flow includes: presetting the dirtiness a0', obtaining the dirtiness a' of the load, comparing the obtained dirtiness a' with the preset dirtiness a0', and if a' ≥ a0', controlling the formation of a reversing pulse water flow.

[0115] If the obtained degree of dirtiness a is greater than or equal to the preset degree of dirtiness a0, it indicates that the current clothes are wear-resistant and have a high degree of dirtiness. At this time, the control is to form a reversing pulse water flow. The pulse water flow can not only flush the clothes in different directions, but also because the speed is variable, the water flow formed has a kneading effect on the clothes in different directions, and the cleaning effect is better.

[0116] As one embodiment of the present invention, during the washing process, the motor is controlled to first generate a uniform, uninterrupted water flow, and then generate a reversed, uninterrupted water flow. At the beginning of washing, it is first necessary to ensure that the clothes can be soaked by the water flow. At this time, the motor is controlled to generate a uniform, uninterrupted water flow to reduce wear on the clothes during the soaking process. After the clothes are soaked, they need to be washed. At this time, the motor is controlled to generate a reversed, uninterrupted water flow to ensure a better cleaning effect on the clothes.

[0117] Preferably, after the reversal of the non-intermittent water flow is completed and before the washing process is completed, the motor is controlled to form a non-intermittent water flow in the same direction; after the reversal of the non-intermittent water flow is completed, the clothes have basically been washed clean, and at this time, the non-intermittent water flow in the same direction is controlled to be formed so that the clothes can be evenly distributed in one direction, preparing for subsequent rinsing and dehydration.

[0118] 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 is running, the motor is controlled to form a non-intermittent water flow in the same direction.

[0119] In this embodiment, the uninterrupted flow of water in the same direction can drive the clothes to rotate in the same direction, so that when the spray program is started, the spray water can be evenly sprayed on the clothes, and the clothes can be fully sprayed and flushed.

[0120] As one implementation of this embodiment, during the washing process, the state of the load in the barrel is detected. If the load in the barrel is in a floating state, a spraying program is executed, and a uniform, uninterrupted water flow is controlled. Specifically, the washing machine of the present invention is provided with a camera for capturing an image of the barrel and determining whether the load is in a floating state based on the captured image.

[0121] In this embodiment, if the clothes are in a floating state, the clothes cannot be fully and effectively washed. At this time, the spray program is controlled to be executed, and the floating clothes are rinsed into the washing water by spraying water. At the same time, the same-direction uninterrupted water flow is controlled to ensure that the spraying water can be fully sprayed on the floating clothes, and then all the floating clothes are rinsed below the liquid level.

[0122] As another implementation of this embodiment, a foam volume V0 is preset, the foam volume V in the barrel is obtained, and the obtained foam volume V is compared with the preset foam volume V0. If V ≥ V0, the spraying process is controlled to form a uniform and continuous water flow. When the spraying process is executed, the drainage process can be simultaneously controlled to start; if V < V0, the spraying process is not executed.

[0123] In this embodiment, the foam volume V in the barrel is obtained in the following manner:

[0124] Method 1: A camera is provided in the washing equipment for collecting images in the barrel, and the amount of foam V in the barrel is obtained based on the collected images.

[0125] Method 2: Install an ultrasonic sensor in the washing equipment. The ultrasonic sensor can be used to monitor foam in the liquid. Specifically, foam usually has relatively special acoustic properties. Its ability to reflect and absorb ultrasonic waves is different from that of water. By studying the differences in the reflection characteristics of foam and water, the presence and amount of foam can be identified and estimated.

[0126] In this embodiment, if the obtained foam amount V is greater than or equal to the preset foam amount V0, it indicates that there is a lot of foam in the barrel body. At this time, it is necessary to control the execution of the spraying program, spray the water in to flush out the foam, and control the formation of a non-intermittent water flow in the same direction so that the spraying water can be evenly and comprehensively sprayed into the barrel body, thereby improving the flushing effect on the foam.

[0127] The present invention also provides a washing machine controlled by any of the control methods described in the above technical solutions. The washing machine includes a barrel for accommodating clothes, a pulsator rotatably disposed in the barrel, and a motor for providing power for the barrel and the pulsator to rotate.

[0128] The motor of the washing device can rotate continuously during the washing process, forming an uninterrupted water flow in the barrel of the washing device, and the uninterrupted water flow circulates continuously without interruption or pause.

[0129] The continuously rotating motor ensures that the wash water is evenly distributed throughout the drum. This helps ensure that the wash water fully soaks the load, improving washing results. The continuous rotation of the motor helps reduce friction between the loads, thereby reducing the likelihood of tangling and tangling, which helps extend the life of the loads and reduce wear and tear. Furthermore, the continuously rotating motor makes the wash water more active, increasing its rinsing effect on clothes, helping to more effectively remove stains, dust, and bacteria, and improving washing efficiency.

[0130] In particular, continuous rotation of the motor can shorten the washing cycle because the washing water can come into contact with the clothes more quickly during rotation, which means that the washing time can be shortened, thereby improving the working efficiency of the washing machine.
