Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

Meanwhile, in the description of the embodiments of the present application, the terms “first”, “second”, and the like are only used for distinguishing description, and cannot be understood as indicating or implying relative importance. Therefore, the features with “first” and “second” can explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of “multiple” is two or more, unless otherwise specifically limited.
[0027] The embodiments of the present application provide a dehydration control method, device, washing machine, and computer readable storage medium.
[0028] Specifically, the embodiments will be described from the perspective of a dehydration control device, which can be integrated in a washing machine, that is, the dehydration control method according to the embodiments of the present application can be executed by a washing machine.
[0029] The dehydration control method provided by the embodiments of the present application can be applied to, for example, a washing machine or a clothes dryer.
[0030] The embodiments will be described in detail below with reference to the drawings. In the embodiments, the execution subject is taken as an example of a washing machine. It should be noted that the description order of the following embodiments is not used as a limitation on the preferred order of the embodiments. Although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown in the drawings.
[0031] Please refer to Figure 1 The specific flow of the dehydration control method includes the following steps:
[0032] In step 101, in response to a dehydration instruction, a single eccentricity and a diagonal eccentricity are obtained.
[0033] Step 102: If the single eccentricity is less than a preset single eccentricity threshold and the diagonal eccentricity is less than a preset diagonal eccentricity threshold, then execute the first dehydration process.
[0034] Step 103: During the execution of the first dehydration process, obtain the motor power;
[0035] Step 104: Based on the motor power and the preset diagonal eccentric power value, execute the second dehydration process.
[0036] In this embodiment, when the washing machine responds to the spin-drying command, it acquires the single eccentricity and the diagonal eccentricity, compares the single eccentricity with a preset single eccentricity threshold, and compares the diagonal eccentricity with a preset diagonal eccentricity threshold. If the single eccentricity is less than the preset single eccentricity threshold and the diagonal eccentricity is less than the preset diagonal eccentricity threshold, then the first spin-drying process is executed. During the execution of the first spin-drying process, the washing machine acquires the motor power, compares the motor power with a preset diagonal eccentricity power value, and executes the second spin-drying process based on the comparison result.
[0037] It should be noted that this is a front-loading washing machine, and the state of the clothes inside the drum is quite complex, resulting in a complex eccentricity. It's less likely to be a single eccentricity, but more likely a diagonal eccentricity. Figure 2 As shown, single eccentricity means the clothes are distributed in the same position within the drum, while diagonal eccentricity means the clothes are distributed in two positions within the drum, with the two positions being diagonally opposite. Single eccentricity detection is called OOB detection, and diagonal eccentricity detection is called DOOB detection. Some drum washing machines only perform OOB detection and not DOOB detection, while others control both OOB and DOOB. Generally, OOB detection is performed at around 100 RPM, and DOOB detection is performed at around 200 RPM. However, the accuracy of DOOB detection is low due to speed fluctuations, especially when the DOOB value is not particularly large. This can easily lead to the washing machine operating in a severely eccentric state. This invention uses a motor power detection method to achieve accurate diagonal eccentricity detection, reducing the risk of severe eccentricity during high-speed spin drying, reducing overall machine vibration and noise, and preventing damage to the washing machine under high-intensity load conditions.
[0038] In this embodiment, the washing machine responds to the spin-drying command and acquires the single eccentricity and diagonal eccentricity. If the single eccentricity is less than a preset single eccentricity threshold and the diagonal eccentricity is less than a preset diagonal eccentricity threshold, a first spin-drying process is executed. During the execution of the first spin-drying process, the motor power is acquired. Based on the motor power and a preset diagonal eccentricity power value, a second spin-drying process is executed. By using a fluctuation method for single eccentricity and diagonal eccentricity detection, and executing the first spin-drying process when both single eccentricity and diagonal eccentricity meet the conditions, and further determining diagonal eccentricity detection based on motor power during the first spin-drying process before executing the second spin-drying process, the accuracy of diagonal eccentricity detection can be improved. This avoids the washing machine operating in a state of severe eccentricity, reduces vibration and noise during the spin-drying process, and lowers the probability of damage to the drum components.
[0039] Specifically, the following provides a detailed explanation of each step:
[0040] Step 101: Respond to the dehydration command and obtain the single eccentricity and diagonal eccentricity.
[0041] In this step, the washing machine responds to the spin-drying command, acquires the single eccentricity and diagonal eccentricity, controls the inner drum to rotate according to a preset single eccentricity detection speed, and then detects the eccentricity during the inner drum's rotation to obtain the single eccentricity. Similarly, it controls the inner drum to rotate according to a preset diagonal eccentricity detection speed, and then detects the diagonal eccentricity during the inner drum's rotation to obtain the diagonal eccentricity. For example, the washing machine can be a front-loading washing machine, which performs washing and spin-drying operations by rotating the inner drum. Optionally, after the washing machine completes the washing operation, it usually performs a spin-drying operation. The washing machine can respond to the spin-drying command according to its own program settings, controlling the inner drum to rotate to obtain the single eccentricity and diagonal eccentricity. Optionally, when the user needs to spin-dry the clothes separately, they can input a spin-drying command into the washing machine, and the washing machine responds to the spin-drying command by controlling the inner drum to rotate to obtain the single eccentricity and diagonal eccentricity.
[0042] Specifically, obtaining the single eccentricity and diagonal eccentricity includes the following steps:
[0043] Step 1011: Control the inner drum of the washing machine to rotate to the first preset speed and obtain the single eccentricity.
[0044] Step 1012: If the single eccentricity is less than the preset single eccentricity threshold, then control the inner cylinder to rotate to the second preset speed to obtain the diagonal eccentricity.
[0045] In steps 1011 to 1012, after the washing machine responds to the spin-drying command, it controls the inner drum of the washing machine to rotate to the first preset speed to obtain the single eccentricity. The washing machine compares the single eccentricity with the preset single eccentricity threshold. If the single eccentricity is less than the preset single eccentricity threshold, it controls the inner drum to rotate to the second preset speed to obtain the diagonal eccentricity. The first preset speed is less than the second preset speed. The first preset speed is the preset single eccentricity detection speed, and the second preset speed is the preset diagonal eccentricity detection speed.
[0046] Furthermore, if the single eccentricity is not less than the preset single eccentricity threshold, the washing machine controls the inner drum to rotate and shake and distribute the clothes in the washing machine until the new single eccentricity is less than the preset single eccentricity threshold. Then, the inner drum is further controlled to rotate to the second preset speed to obtain the diagonal eccentricity.
[0047] Step 102: If the single eccentricity is less than a preset single eccentricity threshold and the diagonal eccentricity is less than a preset diagonal eccentricity threshold, then execute the first dehydration process.
[0048] In this step, after obtaining the single eccentricity and diagonal eccentricity, if the washing machine determines that the single eccentricity is less than a preset single eccentricity threshold and the diagonal eccentricity is less than a preset diagonal eccentricity threshold, then it executes the first spin-drying process. Specifically, the first spin-drying process is a medium-high speed spin-drying process, and the preset single eccentricity threshold and preset diagonal eccentricity threshold are preset in the washing machine.
[0049] Further, prior to step 102, the following steps are included:
[0050] Step 1013: If the single eccentricity is less than the preset single eccentricity threshold, or the diagonal eccentricity is less than the preset diagonal eccentricity threshold, then control the inner drum to rotate to shake and distribute the clothes in the washing machine.
[0051] Step 1014: Obtain the new single eccentricity and diagonal eccentricity;
[0052] In steps 1013 to 1014, if the washing machine determines that the single eccentricity is not less than the preset single eccentricity threshold, the washing machine controls the inner drum to rotate and shake the clothes in the washing machine until the new single eccentricity is less than the preset single eccentricity threshold. Then, the inner drum is further controlled to rotate to the second preset speed to obtain the diagonal eccentricity. If the washing machine determines that the diagonal eccentricity is not less than the preset diagonal eccentricity threshold, the washing machine controls the inner drum to rotate and shake the clothes in the washing machine to obtain new single eccentricity and diagonal eccentricity again.
[0053] Step 1015, until the new single eccentricity is less than the preset single eccentricity threshold and the new diagonal eccentricity is less than the preset diagonal eccentricity threshold.
[0054] In this step, the washing machine continuously acquires new single eccentricity and diagonal eccentricity until the acquired new single eccentricity is less than the preset single eccentricity threshold and the new diagonal eccentricity is less than the preset diagonal eccentricity threshold, then the first dehydration process is executed.
[0055] Furthermore, prior to step 102, the following steps are also included:
[0056] Step a, obtain the preset maximum load weight of the washing machine, place the load of the preset maximum weight in the inner drum and control the inner drum to rotate at a first preset speed to obtain the preset single eccentricity threshold.
[0057] In this step, the washing machine obtains its preset maximum load weight, places the preset maximum load weight in the inner drum, and controls the inner drum to rotate at a first preset speed. If the inner drum does not collide with the washing machine body, a single eccentricity detection is performed, and the measured single eccentricity is used as a preset single eccentricity threshold. If the inner drum will collide with the washing machine body, the rotation speed of the inner drum is reduced until the inner drum does not collide with the washing machine body, and a single eccentricity detection is performed again, with the measured single eccentricity used as a preset single eccentricity threshold. At this time, the corresponding rotation speed is set to the first preset speed for rotation. In subsequent specific applications, single eccentricity detection is performed using this first preset speed.
[0058] Step b: Obtain the maximum resultant torque load distribution information corresponding to the preset maximum load weight; based on the maximum resultant torque load distribution information, place the load of the preset maximum weight in the inner cylinder and control the inner cylinder to rotate at a second preset speed to obtain the preset diagonal eccentricity threshold.
[0059] In this step, the washing machine obtains the maximum resultant torque load distribution information corresponding to the preset maximum load weight. Based on the maximum resultant torque load distribution information, it places the preset maximum weight load in the inner drum and controls the inner drum to rotate at a second preset speed, thus obtaining a preset diagonal eccentricity threshold. It should be noted that the maximum resultant torque load distribution information refers to the distribution information of clothes in the drum of the washing machine to achieve the maximum resultant torque, which can be obtained through experimental testing. Specifically, based on the maximum resultant torque load distribution information, the clothes corresponding to the preset maximum load weight are distributed inside the drum, and then the inner drum is controlled to rotate at a second preset speed. If the inner drum does not collide with the washing machine cabinet, diagonal eccentricity is detected, and the measured diagonal eccentricity is used as a preset diagonal eccentricity threshold. If the inner drum will collide with the washing machine cabinet, the speed of the inner drum is reduced until the inner drum does not collide with the washing machine cabinet, diagonal eccentricity is detected again, and the measured diagonal eccentricity is used as a preset diagonal eccentricity threshold. At this time, the corresponding speed is set to the second preset speed for rotation. In subsequent specific applications, diagonal eccentricity detection is performed by rotating at this second preset speed.
[0060] Step 103: During the execution of the first dehydration process, obtain the motor power;
[0061] In this step, during the execution of the first spin-drying process, the washing machine continuously increases its speed from the second preset speed to the highest speed set for the first spin-drying process. During this process, the washing machine detects whether the speed of the first spin-drying process has reached the preset speed for obtaining motor power. If it has, the washing machine obtains the motor power.
[0062] Specifically, step 103 includes:
[0063] Step 1031: Control the inner cylinder to rotate at the second preset speed, and control the rotation speed of the inner cylinder to increase from the second preset speed to the third preset speed;
[0064] Step 1032: When the rotational speed of the inner cylinder is detected to reach the third preset rotational speed, the motor power is obtained.
[0065] In steps 1031 and 1032, during the execution of the first spin-drying process, the washing machine's rotation speed continuously increases from the second preset speed to the third preset speed. It can be understood that the third preset speed can be the maximum speed set for the first spin-drying process and the preset speed for obtaining motor power; that is, the maximum speed set for the first spin-drying process and the preset speed for obtaining motor power are the same. Alternatively, the third preset speed can be the preset speed for obtaining motor power, and the third preset speed is less than the maximum speed set for the first spin-drying process. The washing machine detects whether the rotation speed of the first spin-drying process has reached the third preset speed. When it detects that the inner drum's rotation speed has reached the third preset speed, it obtains the motor power.
[0066] Step 104: Based on the motor power and the preset diagonal eccentric power value, execute the second dehydration process.
[0067] In this step, after obtaining the motor power, the washing machine executes the second spin-drying process based on the motor power and the preset diagonal eccentric power value. This second spin-drying process includes high-speed spin-drying, maintaining medium-high speed spin-drying, or shaking and distributing the clothes until it is determined that high-speed spin-drying can be performed.
[0068] Specifically, step 104 includes:
[0069] Step 1041: Compare the motor power with the preset diagonal eccentricity power value;
[0070] Step 1042: If the motor power is less than the preset diagonal eccentric power value, then control the rotation speed of the inner drum to increase from the third preset rotation speed to the preset maximum rotation speed to spin-dry the clothes in the washing machine;
[0071] Step 1043: If the motor power is not less than the preset diagonal eccentricity power value, then control the inner drum to maintain the third preset rotation speed to spin-dry the clothes in the washing machine, or control the inner drum to rotate to shake and distribute the clothes, and repeat the step: obtain the single eccentricity and diagonal eccentricity.
[0072] In steps 1041 to 1043, after obtaining the motor power, the washing machine compares the motor power with the preset diagonal eccentricity power value. If the motor power is less than the preset diagonal eccentricity power value, it indicates that the diagonal eccentricity meets the corresponding condition. The washing machine then controls the inner drum's rotation speed to increase from the third preset speed to the preset maximum speed to spin-dry the clothes in the washing machine. If the motor power is not less than the preset diagonal eccentricity power value, it indicates that the diagonal eccentricity does not meet the corresponding condition. The inner drum is controlled to maintain the third preset speed to spin-dry the clothes in the washing machine, or the inner drum is controlled to rotate to shake and distribute the clothes, and the steps are repeated: obtaining the single eccentricity and diagonal eccentricity until it is determined that the motor power is less than the preset diagonal eccentricity power value, and the inner drum's rotation speed is controlled to increase from the third preset speed to the preset maximum speed to spin-dry the clothes in the washing machine.
[0073] It is understandable that, such as Figure 3 As shown, the eccentricity generates an eccentric centrifugal force F = mrω when the inner cylinder rotates. 2 In the formula, m is the eccentric mass, r is the eccentric radius of rotation, ω is the angular velocity of the cylinder, and the resultant torque formed by the diagonal eccentricity at the front support point A of the shaft is M = F. F L F -F R L R The deformation of the inner cylinder front end under different diagonal eccentricity conditions is calculated by simulation. The deformation of the inner cylinder front end can be regarded as the load strength of the cylinder. The diagonal eccentricity, resultant moment and deformation of the inner cylinder front end are listed in the table below. In the table, F represents the eccentricity at the front of the cylinder and R represents the diagonal eccentricity at the rear of the cylinder.
[0074]
[0075] The data in the table above shows that the deformation at the front end of the inner cylinder, i.e., the load-bearing strength of the cylinder, is directly proportional to the resultant torque. The eccentric states shown in the table above were tested sequentially on the test prototype, and the power values of the motor were monitored and recorded. The results are shown in the table below:
[0076]
[0077] As can be seen from the data in the table above, the deformation at the front end of the inner cylinder, i.e., the load-bearing strength of the cylinder, is directly proportional to the motor power. Therefore, the load-bearing strength of the cylinder can be determined by detecting the motor power value.
[0078] Therefore, when the motor power is less than the preset diagonal eccentricity power value, it means that the load strength of the drum caused by the diagonal eccentricity is not greater than the drum's bearing capacity, and the drum will not collide with the washing machine body to produce vibration and noise.
[0079] Further, prior to step 104, the following steps are included:
[0080] Step c: Obtain the preset maximum load weight and maximum spin speed of the washing machine, as well as the inner drum length of the washing machine;
[0081] Step d: Calculate the maximum resultant torque based on the preset maximum load weight, the maximum rotational speed, and the inner cylinder length;
[0082] Step e: Calculate the preset diagonal eccentricity power value based on the maximum resultant torque and the maximum rotational speed.
[0083] In steps c to e, the washing machine obtains its preset maximum load weight and maximum speed, as well as the inner drum length. Based on the preset maximum load weight, the maximum speed, and the inner drum length, it calculates the maximum resultant torque. Based on the maximum resultant torque and the maximum speed, it calculates the preset diagonal eccentricity power value. Specifically, it is assumed that the load of the preset maximum load weight is placed in a position such as... Figure 3 The eccentric position at the front of the cylinder shown indicates the maximum calculated resultant moment. The formula for calculating the maximum resultant moment is: T = ML F ω 2 Where T is the maximum resultant torque, M is the preset maximum load weight, and L is the maximum torque. F Let P be the length of the inner cylinder, and ω be the angular velocity at maximum rotational speed. The formula for calculating the preset diagonal eccentricity power value is: P = Tω, where P is the preset diagonal eccentricity power value, T is the maximum resultant torque, and ω is the angular velocity at maximum rotational speed.
[0084] In this embodiment, the washing machine responds to the spin-drying command and acquires the single eccentricity and diagonal eccentricity. If the single eccentricity is less than a preset single eccentricity threshold and the diagonal eccentricity is less than a preset diagonal eccentricity threshold, a first spin-drying process is executed. During the execution of the first spin-drying process, the motor power is acquired. Based on the motor power and a preset diagonal eccentricity power value, a second spin-drying process is executed. By using a fluctuation method for single eccentricity and diagonal eccentricity detection, and executing the first spin-drying process when both single eccentricity and diagonal eccentricity meet the conditions, and further determining diagonal eccentricity detection based on motor power during the first spin-drying process before executing the second spin-drying process, the accuracy of diagonal eccentricity detection can be improved. This avoids the washing machine operating in a state of severe eccentricity, reduces vibration and noise during the spin-drying process, and lowers the probability of damage to the drum components.
[0085] In specific implementation, refer to Figure 4In response to the spin-drying command, the washing machine controls the inner drum to rotate and distribute the clothes inside. Next, the inner drum rotates at a first speed to perform OOB (Out-of-Body) detection (single eccentricity detection), obtaining an OOB value. This OOB value is compared to an OOB limit (a preset single eccentricity threshold). If the OOB value is not less than the OOB limit, the inner drum rotates again to distribute the clothes, and the rotation is repeated at the first speed until the OOB value is less than the OOB limit. Then, the inner drum rotates at a second speed to perform DOOB (Diagonal eccentricity detection). The DOOB detection value is obtained and compared with the DOOB limit (preset diagonal eccentricity threshold). If the DOOB detection value is not less than the DOOB limit, the inner drum is controlled to rotate to shake and distribute the clothes in the washing machine. The inner drum is then controlled to rotate at the first speed to perform OOB detection until the OOB detection value is less than the OOB limit. The inner drum is then controlled to rotate at the second speed to perform DOOB detection (diagonal eccentricity detection) to obtain the DOOB detection value. The process continues until both the OOB detection value and the DOOB detection value are less than the DOOB limit. Then, a medium-high speed spin-drying process is performed (first spin-drying cycle).
[0086] During the dehydration process at medium and high speeds, when the inner cylinder speed reaches the third speed, the DOOB detection power value (motor power) is obtained. The DOOB detection power value is compared with the motor power limit (preset diagonal eccentric power value). If the DOOB detection power value is less than the motor power limit, high-speed dehydration is performed until the dehydration ends. If the DOOB detection power value is not less than the motor power limit, the current third speed is maintained until the dehydration ends.
[0087] Further reference Figure 5 If the DOOB detection power value is not less than the motor power limit, the inner drum is controlled to rotate to shake and distribute the clothes in the washing machine. The inner drum is then controlled to rotate at the first speed to perform OOB detection until the OOB detection value is less than the OOB limit. The inner drum is then controlled to rotate at the second speed to perform DOOB detection (diagonal eccentricity detection) to obtain the DOOB detection value. This process continues until both the OOB detection value and the DOOB detection value are less than the DOOB limit. The inner drum is then controlled to rotate at the third speed to obtain the DOOB detection power value. This process continues until the DOOB detection power value is less than the motor power limit, at which point high-speed spin drying is performed until the spin drying ends.
[0088] This embodiment also provides a dehydration control device, which can be integrated into devices such as washing machines and dryers. Figure 6 As shown, the dehydration control device may include:

[0102] If the motor power is less than the preset diagonal eccentric power value, the rotation speed of the inner drum is controlled to increase from the third preset rotation speed to the preset maximum rotation speed to spin-dry the clothes in the washing machine;
[0103] If the motor power is not less than the preset diagonal eccentricity power value, then the inner drum is controlled to rotate at the third preset speed to spin-dry the clothes in the washing machine, or the inner drum is controlled to rotate to shake and distribute the clothes, and the steps of obtaining single eccentricity and diagonal eccentricity are executed again.
[0104] In an optional example, the first execution unit is also used for:

[0111] In an optional example, determining the cell is also used for:
[0112] Obtain the preset maximum load weight and maximum spin speed of the washing machine, as well as the inner drum length of the washing machine;
[0113] The maximum resultant torque is calculated based on the preset maximum load weight, the maximum rotational speed, and the inner cylinder length.
[0114] Based on the maximum resultant torque and the maximum rotational speed, a preset diagonal eccentricity power value is calculated.
[0115] The solution in this embodiment responds to the spin-drying command and acquires the single eccentricity and diagonal eccentricity. If the single eccentricity is less than a preset single eccentricity threshold and the diagonal eccentricity is less than a preset diagonal eccentricity threshold, a first spin-drying process is executed. During the execution of the first spin-drying process, the motor power is acquired. Based on the motor power and a preset diagonal eccentricity power value, a second spin-drying process is executed. By using a fluctuation method for single eccentricity and diagonal eccentricity detection, and executing the first spin-drying process when both single eccentricity and diagonal eccentricity meet the conditions, and further determining diagonal eccentricity detection based on motor power during the first spin-drying process before executing the second spin-drying process, the accuracy of diagonal eccentricity detection can be improved. This avoids the washing machine operating in a state of severe eccentricity, reduces vibration and noise during the spin-drying process, and lowers the probability of damage to the drum components.

[0120] The touch display screen 1103 can be used to display a graphical user interface (GUI) and receive operation commands generated by the user interacting with the GUI. The touch display screen 1103 may include a display panel and a touch panel. The display panel can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the electronic device.

Optionally, the display panel can be configured using a liquid crystal display (LCD), organic light-emitting diode (OLED), or other similar technologies. The touch panel can be used to collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel), generate corresponding operation commands, and execute the corresponding program according to the operation commands. Optionally, the touch panel may include a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller.

It can also receive and execute commands from the processor 1101. The touch panel can cover the display panel. When the touch panel detects a touch operation on or near it, it transmits the information to the processor 1101 to determine the type of touch event. Subsequently, the processor 1101 provides corresponding visual output on the display panel based on the type of touch event. In this embodiment, the touch panel and the display panel can be integrated into the touch display screen 1103 to achieve input and output functions.

Audio circuit 1105 can convert received audio data into electrical signals and transmit them to the speaker, where the speaker converts them into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 1105, converted back into audio data, and then processed by processor 1101 before being transmitted via radio frequency circuit 1104 to, for example, another electronic device, or output to memory 1102 for further processing. Audio circuit 1105 may also include an earphone jack to provide communication between peripheral headphones and electronic devices.
