[0058] The present application provides a washing machine dehydration control method, device, washing machine and storage medium. After the washing machine enters the dehydration stage, it is determined whether the active eccentricity compensation system is normal; according to the normal active eccentricity compensation system, the active eccentricity compensation system is used to perform real-time eccentricity detection and active eccentricity compensation on the dehydration tub until the eccentricity detection is qualified, and dehydration control is performed according to the current state of the dehydration motor, the water level state in the dehydration tub, and a preset first dehydration program; according to the abnormal active eccentricity compensation system, dehydration control is performed according to a preset second dehydration program. Compared with the prior art, in the present application, the corresponding dehydration program can be selected according to the state of the active eccentricity compensation system for dehydration control, which can avoid the weakening of dehydration performance caused by the abnormality of the active eccentricity compensation system, so that the washing machine obtains better balance and dehydration performance.

[0059] To make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be given with reference to the accompanying drawings.

[0060] Figure 1 It is a flowchart of a washing machine dehydration control method provided by an embodiment of the present application. As Figure 1 shown, the washing machine dehydration control method includes:

[0061] Step S101: Determine whether the active eccentricity compensation system is normal according to the washing machine entering the dehydration stage.

[0062] Step S102: Perform dehydration control according to the current state of the dehydration motor, the water level state in the dehydration tub, and a preset first dehydration program, and the first dehydration program includes using the active eccentricity compensation system to perform real-time eccentricity detection and active eccentricity compensation on the dehydration tub.

[0063] Step S103: Based on the abnormality of the active eccentricity compensation system, dehydration control is performed according to the current state of the dehydration motor, the water level state in the dehydration tub, and a preset second dehydration program.

[0064] The washing machine in this embodiment can be any type of washing machine, such as a drum washing machine. The dehydration stage can be the post-washing dehydration stage, the post-rinsing dehydration stage, or the spin-drying dehydration stage.

[0065] In practical applications, the dehydration tub rotates driven by the dehydration motor. When the dehydration tub rotates for dehydration, if the load distribution in the dehydration tub is uneven (the load is the clothes to be dehydrated), it will cause the center of gravity of the load in the dehydration tub to deviate, that is, there is load eccentricity. If the dehydration tub has load eccentricity, vibration will be generated during rotation. When the eccentricity degree is relatively large, the dehydration tub cannot enter the high-speed rotation stage, that is, effective dehydration cannot be achieved.

[0066] It should be understood that the dehydration program in this embodiment can be that when the washing machine enters the dehydration stage, the eccentricity of the dehydration tub is detected in real time to obtain the eccentricity value, and the dehydration motor is controlled according to the eccentricity value so that the dehydration speed of the dehydration tub increases in stages.

[0067] In this embodiment, the active eccentricity compensation system can detect the eccentricity of the dehydration tub and perform active eccentricity compensation. The active eccentricity compensation system can specifically include 2 vibration sensors (for example, acceleration sensors), which are arranged at the front and rear positions of the outer tub of the washing machine, and also includes a balance ring and a balance mass unit (abbreviated as balance block). At least 2 balance blocks are arranged in the balance ring. The balance ring is arranged on the dehydration cylinder of the washing machine, and there are at least 2 symmetric reset marks in the balance ring; the balance block has a Hall sensor for calculating the number of rotations of the dehydration motor and identifying the reset marks in the balance ring.

[0068] The specific control process of the active eccentricity compensation system: The vibration sensor identifies the vibration of the washing machine during dehydration, and selects the action of reducing vibration according to the change of the vibration signal to control the balance block.

[0069] As Figure 2 shown, this embodiment provides a schematic diagram of an active eccentricity compensation system. Among them, components A and B are two balance blocks that can control balance, and each balance block has a control board for controlling the movement of the balance block; component E is a middle set board, which is equipped with a wireless receiving module and a receiving board; component G is a balance control board, which includes a wireless transmitting module, a variable-frequency power supply, and a communication part with the main control F; component F is the main control board of the washing machine, which is connected to component G through a UART (Universal Asynchronous Receiver-Transmitter) port; the balance ring is used to detect the position of the balance block in real time and transmit the information to component E.

[0070] It should be understood that the execution subject of this embodiment can be the main control board F of the washing machine or the balance control board G.

[0071] The compensation principle of the active eccentricity compensation system is as follows:

[0072] The first part: Balance weights A and B are reset when the washing machine is started and powered on. There are reset marks on the balance ring. When a reset command is received, the balance weights are reset. There are two symmetric reset marks, with one balance weight corresponding to each reset mark. During the dehydration process of the washing machine, the balance weights continuously adjust their positions. By means of the relative movement of the two balance weights, the opposite movement of the two balance weights, the same-direction clockwise movement of the two balance weights, and the same-direction counterclockwise movement of the two balance weights, the resultant force of the four movement modes changes the balance state. When the speed is below 400 rpm, the balance weights can directly adjust the balance at the current speed of the dehydration motor. Between 400 rpm and 800 rpm, the speed of the dehydration motor needs to return to the previous maintenance stage, and then the balance weights perform balance adjustment.

[0073] The second part: The middle collecting plate E is equipped with a wireless module and a receiving module. The wireless module is used for wireless data transmission and communication with the balance control board G of the component, receiving the control commands issued by the balance control board G of the component. During dehydration, it continuously feeds back the balance state sensed by the current balance weights and receives the adjustment instructions for the current balance. The receiving module is used to provide power to the middle collecting plate E. By the principle of electro-magnetic generation and magnetic regeneration of electricity, the power provided by the transmitting plate in the balance control board G of the component is converted into the power for the middle collecting plate E for the middle collecting plate E to use.

[0074] The third part: The balance control board G includes a wireless module, a variable-frequency power supply, a transmitting module, and a communication part with the main control board F. The wireless module is used for wireless data transmission and communication with the middle collecting plate E of the component, sending the control commands issued to the middle collecting plate E. During dehydration, it continuously receives the balance state sensed by the current balance weights and sends the adjustment instructions for the current balance. The variable-frequency power supply is used to convert the 220V voltage into a 24V voltage. The transmitting module is used to generate a magnetic field through a wire with 24V electricity and cooperate with the receiving module in the middle collecting plate E to generate electricity transmission. The communication part with the main control board F communicates with the main control board F of the washing machine through the UART port to obtain the state of the washing machine, such as whether it is in the dehydration state or the just-powered-on state currently.

[0075] The fourth part: The balance control board F is the main controller of the washing machine, which contains the logical control algorithm for the entire operation of the washing machine (including the dehydration program), controls the different actions or reactions to be performed by the washing machine at the same stage, maintains real-time communication with the balance control board G, timely feeds back the current state of the washing machine, and controls the washing machine in case of abnormal situations.

[0076] In this application, the first dehydration program includes using the active eccentricity compensation system to detect eccentricity of the dehydration tub in real time and perform active eccentricity compensation. In the second dehydration program, the dehydration motor can be used to detect eccentricity, but it does not include active eccentricity compensation.

[0077] In this application, the reason for determining whether the active eccentricity compensation system is normal after the washing machine enters the dehydration stage is that when the active eccentricity compensation system is abnormal, accurate eccentricity compensation cannot be performed, resulting in the inability to operate the preset first dehydration program properly and errors in operation, or in other words, poor dehydration effect and degraded dehydration performance. When the active eccentricity compensation system is abnormal, the preset second dehydration program is used for dehydration in this application. The second dehydration program does not require the active eccentricity compensation system, minimizing the impact of the abnormal active eccentricity compensation system and enabling the washing machine to achieve better balance and dehydration performance.

[0078] Specifically, determining whether the active eccentricity compensation system is normal in step S101 can be implemented as follows:

[0079] Send a balance weight reset command to the active eccentricity compensation system;

[0080] Obtain the reset result of the balance weight in the active eccentricity compensation system;

[0081] Determine whether the active eccentricity compensation system is normal according to the reset result.

[0082] Furthermore, determining whether the active eccentricity compensation system is normal according to the reset result includes: determining that the active eccentricity compensation system is abnormal according to the reset result being a reset failure and the number of times being greater than the preset number of times or the cumulative reset time being greater than the upper limit time.

[0083] Specifically, if the balance weight reset fails and the number of times exceeds 3 times, it can be determined that the active eccentricity compensation system is abnormal. Or, if the cumulative balance weight reset time is greater than the upper limit time, that is, the reset is not completed within the upper limit time, it can also be determined that the active eccentricity compensation system is abnormal. The upper limit time and the preset number of times can be set according to the actual situation, and this application does not make any limitations in this regard.

[0084] Furthermore, determining whether the active eccentricity compensation system is normal according to the reset result also includes:

[0085] According to the reset result being a successful reset, send a request to establish dehydration control communication to the active eccentricity compensation system; determine that the active eccentricity compensation system is normal according to receiving a confirmation message replied by the active eccentricity compensation system within the preset time; determine that the active eccentricity compensation system is abnormal according to not receiving a confirmation message replied by the active eccentricity compensation system within the preset time.

[0086] Specifically, if the balance weight is successfully reset, a request to establish dehydration control communication is sent to the active eccentricity compensation system. If an acknowledgement message is received from the active eccentricity compensation system within a preset time, it can be determined that the active eccentricity compensation system is normal, and then dehydration control communication can be established. For example, the main control board F of the washing machine can call the CommunicateWithAbc function to establish dehydration control communication with the balance control board G to enable dehydration control communication.

[0087] If an acknowledgement message is not received from the active eccentricity compensation system within the preset time, it can be determined that the active eccentricity compensation system is abnormal, and there is no need to establish dehydration control communication with the active eccentricity compensation system to avoid weakening of dehydration performance caused by the abnormality of the active eccentricity compensation system.

[0088] It can be understood that in this embodiment, when the active eccentricity compensation system is normal, during the first dehydration program, the active eccentricity compensation system is used to detect the eccentricity of the dehydration tub in real time and perform active eccentricity compensation until the eccentricity detection is qualified. Then, dehydration control is performed according to the current state of the dehydration motor, the water level state in the dehydration tub, and the preset first dehydration program to obtain better balance and dehydration performance. When the active eccentricity compensation system is abnormal, the preset second dehydration program is used for dehydration control to minimize the impact caused by the abnormality of the active eccentricity compensation system and enable the washing machine to obtain better balance and dehydration performance.

[0089] In this embodiment, in step S102, if the active eccentricity compensation system is normal, dehydration control is performed according to the preset first dehydration program, including:

[0090] First, the main control board F of the washing machine obtains the state of the washing machine, including: querying the current state of the dehydration motor, including speed, climbing or maintaining; and the water level state;

[0091] Second, the main control board F of the washing machine sends the state of the washing machine to the balance control board G and waits for the reply time from the balance control board G;

[0092] Third, the main control board F of the washing machine obtains the control message from the balance control board G, including the target speed, acceleration time, stage target speed, drain pump state, and whether defoaming is required; when abnormally suspended, the main control board F of the washing machine performs defoaming control or other alarm processing;

[0093] Fourth, the main control board F of the washing machine sends an execution instruction to the dehydration motor according to the control message from the balance control board G;

[0094] Fifth, when the control of the dehydration ends normally or the abnormal processing such as defoaming is completed, the control of the balance control board G ends.

[0095] In this embodiment, in step S103, if the active eccentricity compensation system is abnormal, dehydration control is performed according to the current state of the dehydration motor, the water level state in the dehydration tub, and a preset second dehydration program, including:

[0096] According to the abnormality of the active eccentricity compensation system, a request for performing a preset second dehydration program is sent to the active eccentricity compensation system; according to receiving the confirmation message replied by the active eccentricity compensation system or waiting for the reply time to timeout, dehydration control is started according to the current state of the dehydration motor, the water level state in the dehydration tub, and the preset second dehydration program; after dehydration is completed, a balance weight reset instruction is sent to the active eccentricity compensation system.

[0097] Specifically, sending a balance weight reset instruction to the active eccentricity compensation system after dehydration is completed is to determine again whether the active eccentricity compensation system is normal. If the active eccentricity compensation system returns to normal, eccentricity detection and active eccentricity compensation can be performed using the active eccentricity compensation system in the next dehydration stage.

[0098] The dehydration control method of the washing machine according to the embodiment of the present application determines whether the active eccentricity compensation system is normal after the washing machine enters the dehydration stage; according to the normal active eccentricity compensation system, the active eccentricity compensation system is used to perform real-time eccentricity detection and active eccentricity compensation on the dehydration tub, and dehydration control is performed according to the current state of the dehydration motor, the water level state in the dehydration tub, and a preset first dehydration program; according to the abnormality of the active eccentricity compensation system, dehydration control is performed according to a preset second dehydration program. Compared with the prior art, in the present application, the corresponding dehydration program can be selected according to the state of the active eccentricity compensation system for dehydration control, which can avoid the weakening of dehydration performance caused by the abnormality of the active eccentricity compensation system, so that the washing machine obtains better balance and dehydration performance.

[0099] According to the above embodiment, Figure 3 A flowchart showing a specific dehydration control method of the present application is shown in Figure 3 As shown, the dehydration control method of the washing machine includes:

[0100] Step S201: Enter the dehydration stage, start;

[0101] Step S202: Initialize relevant parameters; the relevant parameters may include parameters such as motor defoaming, balance weight reset time, waiting time for the active eccentricity compensation system to reply, and other parameters;

[0102] Step S203: Send a balance weight reset instruction to the active eccentricity compensation system;

[0103] Step S204: Obtain the reset result of the balance weight in the active eccentricity compensation system; if the reset result is OK, jump to step S205; if the reset result is NG, and the number of NG times is greater than 3 times or the reset cumulative time is greater than the upper limit time, jump to step S206;

[0104] Step S205: Send a request to establish dehydration control communication to the active eccentricity compensation system;

[0105] Step S206: Send a request to perform a preset second dehydration program to the active eccentricity compensation system;

[0106] Step S207: Determine whether an acknowledgment message is received from the active eccentricity compensation system; if so, jump to step S208; if not, jump to step S209;

[0107] Step S208: Perform dehydration control according to the preset first dehydration program;

[0108] Step S209: Wait for the acknowledgment message from the active eccentricity compensation system to time out; if so, jump to step S206;

[0109] Step S210: Receive the acknowledgment message from the active eccentricity compensation system or the waiting reply time times out;

[0110] Step S211: Perform dehydration control according to the preset second dehydration program;

[0111] Step S212: After dehydration is completed, send a balance weight reset instruction to the active eccentricity compensation system.

[0112] In this embodiment, it is possible to improve the situation of large eccentricity and poor balance during the execution of washing machine dehydration, increasing the success rate of high-speed dehydration and the stability of high-speed climbing and maintenance.

[0125] According to the reset result being a successful reset, send a request to establish dehydration control communication to the active eccentricity compensation system;

[0126] Determine that the active eccentricity compensation system is normal according to receiving a confirmation message replied by the active eccentricity compensation system within a preset time;
