[0002] The commonly used damping component frictional damping is a constant value, but different damping is needed in different working stages of the washing machine, such as low-speed working stage, high-speed working stage, and drum resonance stage caused by a certain speed. Therefore, if a damping with a constant damping value is used, the different damping requirements of the washing machine cannot be met, resulting in poor damping effect and possible damage to the washing machine. SUMMARY

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0077] This application provides a washing machine control method, apparatus, device, and storage medium, which are described in detail below.

[0078] Please see Figure 1 , Figure 1 This is a schematic diagram of a washing machine control system provided in an embodiment of this application. The washing machine control system may include a washing machine 100 and a storage device 200, which can transmit data to the washing machine 100.

[0081] It should be noted that, Figure 1The scenario diagram of the washing machine control system shown is only an example, and the washing machine control system and scenario described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, as the washing machine control system evolves and new business scenarios appear, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0082] As shown in Figure 2 Figure 2 is an embodiment flow diagram of a washing machine control method in the embodiments of the present application. The washing machine control method is applied to a washing machine. The washing machine includes a first cavity, a second cavity, a third cavity, a motor, and a damper. The damper includes a damper body and a boom. The damper body is arranged above the boom. A friction layer that changes in response to heat is arranged between the damper body and the boom. The first cavity is arranged inside the second cavity. The second cavity is arranged inside the third cavity. A damper cavity is arranged on the outer wall of the second cavity. The damper body is arranged in the damper cavity. The boom is connected to the third cavity. The damper is electrically connected to the power supply of the washing machine. The motor is connected to the first cavity, so that when the motor rotates, the first cavity is driven to rotate. The washing machine control method can include the following steps 201-202.

[0083] 201. Obtain the motor speed of the motor.

[0084] In the embodiments of the present application, the motor speed of the motor can be obtained according to the corresponding sensor. For example, for a traditional direct current motor, a washing machine usually uses a Hall sensor or an optical encoder sensor, which can measure the rotation speed of the motor. The Hall sensor obtains the rotation speed of the motor by detecting the change of the rotating magnetic field. The optical encoder sensor uses a rotating encoder disc fixed on the motor shaft to generate an optical signal in rotation, thereby calculating the rotation speed and direction of the motor. For a modern variable frequency motor, an electronic controller is usually used to control the rotation speed and torque of the motor. The electronic controller includes some sensors, such as a Hall sensor, a current sensor, and a temperature sensor. These sensors can help the electronic controller to detect the running state of the motor in real time, thereby realizing the speed regulation and control of the motor. In summary, the rotation speed of the motor inside the washing machine is usually measured by a sensor and fed back to the controller, so that the controller can regulate and control the motor.

[0085] ​In addition, it should be noted that in the embodiments of the present application, the first cavity of the washing machine can be a cavity for accommodating clothes, which will rotate with the motor to drive the rotation of the first cavity or part of the first cavity to perform the clothes washing process. The second cavity is the accommodating cavity of the first cavity, which is used to protect the first cavity, and the second cavity can be a stationary cavity. Specifically, the motor can be installed on the inner wall bottom of the second cavity, and the rotor of the motor is connected with the part of the first cavity that needs to rotate. Alternatively, the motor can be installed in any free space inside the washing machine, and at this time, the rotor of the motor can be connected with the first cavity through a transmission device, and at this time, there can be a hole in the second cavity, so that the transmission device can pass through the hole and be connected with the first cavity. How the motor is connected with the first cavity is not limited in the embodiments of the present application.

[0086] 202. If the motor speed increases, the current passing through the friction layer is increased to increase the damping value of the damper.

[0087] After the motor speed is monitored in real time according to the above steps, if it is monitored that the motor speed increases, for example, when the washing machine enters the dehydration mode to dehydrate the clothes, the motor gradually increases the speed to improve the dehydration effect of the clothes inside. At this time, the damper can be powered to increase the damping of the damper to provide better damping effect for the first cavity with high speed. Specifically, the structure of the damper can be as shown in Figure 3 and Figure 4 The structure of the damper is shown in the drawings. Figure 3 The structure of the damper is shown in the drawings. Figure 4 The specific structure inside the damper includes a friction layer 500, a protective shell 600, and a circuit via hole 700. The friction layer 500 specifically includes a friction material layer 501 and a heat deformation layer 502.

[0088] The purpose of adding the friction layer 500 in the embodiments of the present application is to increase the size of the friction. The specific reason is that the wire contacts the heat deformation layer 502 through the circuit via hole 700, and when the current in the wire increases, the temperature of the wire also rises, so that the heat deformation layer 502 expands under the heat, increases the pressure on the hanger 400, and further increases the friction between the friction material layer 501 and the hanger. Therefore, increasing the friction layer 500 can increase the friction between the damper and the hanger 400, and further improve the damping effect of the damper. In addition, the friction material layer can be a high-temperature-resistant non-metallic material layer, such as ceramic, silicon carbide, etc. The specific embodiments of the present application are not limited.

[0089] In addition, reference can be made to Figure 5 , Figure 5As shown in Fig. 8, a schematic diagram of the position of the damper in the washing machine includes a first cavity 800, a second cavity 900, a third cavity 1000, and a damper cavity 1100, wherein the damper is arranged in the damper cavity 1100. Meanwhile, the hanger 400 is connected with the third cavity 1000, so that the first cavity 800 and the second cavity 900 are supported by the damper through the hanger 400. It should be noted that other support and fixing structures between the third cavity 1000 and the second cavity 900 are not shown in the figure. Thus, based on the fact that Figure 5 , Figure 5 , Figure 3 , Figure 4 and Figure 5 , when the first cavity 800 of the washing machine rotates or part of the structure of the first cavity 800 rotates, for example, the bottom of the first cavity 800 rotates, the size of the current supplied to the damper is increased, so that the damping value of the damper changes, and thus the damper can better dampen the first cavity 800. In addition, it should be noted that the number of dampers installed in the washing machine is not limited to two in the above embodiment, but can be set according to actual conditions, and the specific number is not limited herein. In addition, the current supplied to the friction layer can be increased in a step-by-step manner. Figure 5

[0090] The washing machine control method provided in the present application adds a friction layer that changes in response to heat in the damper, and thus when the speed of the washing machine is higher during the operation of the washing machine, the current supplied to the damper is increased, so that the temperature of the damper after being supplied with current is increased, and thus the damping value of the damper is increased. Further, when the speed of the washing machine is increased, the required damping level is also higher. Therefore, after the damping value of the damper is increased, the damper can better provide damping effect for the washing machine and reduce the possibility of damage to the washing machine.

[0091] In order to better implement the present application, in one embodiment of the present application, the current supplied to the friction layer is increased to increase the damping value of the damper, including:

[0092] determining a speed increase change value of the increased motor speed; determining a to-be-increased damping value according to a preset speed-damping conversion coefficient and the speed increase change value; determining a to-be-increased current according to a preset damping-current conversion coefficient and the to-be-increased damping value; and increasing the to-be-increased current to the friction layer to increase the damping value of the damper.

[0093] ​However, in the above embodiment, only a scheme of increasing the current when the motor speed increases is provided. Although this way can improve the damping value, the accuracy of the improvement can be further improved. For example, during the experimental stage, the relationship between the unit motor speed and the damping value can be determined through experimental data, and a linear function is fitted, and the slope of the linear function is the preset speed-damping conversion coefficient. At this time, according to the motor speed acquisition method in the above embodiment, after the speed increase change value is determined, the speed increase change value is multiplied by the speed-damping conversion coefficient, and the damping value to be increased can be obtained.

[0094] Then, the damping current conversion coefficient between the unit change damping value and the unit current can also be determined by experimental means. At this time, the damping value to be increased is multiplied by the damping current conversion coefficient, and the current to be increased can be obtained.

[0095] When the current to be increased is determined, the damper is powered according to the specific current value of the current to be increased. In this way, the specific damping increase value of the damper can be effectively controlled, and the damping increase value is too large or too small, which cannot meet the actual damping demand.

[0096] In order to better realize the embodiment of the present application, in an embodiment of the present application, the current to the friction layer is increased to increase the damping value of the damper, comprising:

[0097] The current to the friction layer is increased according to the preset power-on maintenance time. If the circuit temperature of the power-on circuit to the friction layer is detected after the power-on maintenance time, if the circuit temperature is greater than or equal to the preset temperature threshold, the current power-on current is maintained; if the circuit temperature is less than the temperature threshold, the current size of the power-on current is increased again until the circuit temperature is greater than or equal to the temperature threshold.

[0098] The above embodiment provides a scheme for fine control of the damping increase value. However, in actual situations, if the power-on time of the damper according to the current to be increased is short, the temperature change of the heat-deformed layer of the damper may not meet the specific requirements, so a certain power-on maintenance time is needed to make the heat-deformed layer receive a high enough temperature to deform. At the same time, in the embodiment of the present application, a temperature sensor can also be arranged to monitor the temperature of the heat-deformed layer. If the temperature reaches a certain degree, the current can be maintained. If the temperature cannot reach the ideal state for a long time, the size of the power-on current is gradually increased until the set temperature threshold is reached.

[0099] In order to better realize the embodiment of the present application, in an embodiment of the present application, the current to the friction layer is increased to increase the damping value of the damper, comprising:

[0100] If the motor speed decreases, the current applied to the friction layer is reduced to reduce the damping value of the damper.

[0101] The above embodiment provides a scenario that requires an increase in the damping value. However, after the laundry is gradually completed, the motor speed gradually decreases from the peak value. At this time, the damping value of the damper does not change, which may cause the problem of excessive damping and excessive buffering force to the first cavity. Therefore, at this time, the current applied to the friction layer can be reduced to reduce the damping value of the damper. Specifically, as in the above embodiment, the current applied to the friction layer can be gradually reduced.

[0102] To better implement the embodiments of the present application, in an embodiment of the present application, the current applied to the friction layer is reduced to reduce the damping value of the damper, comprising:

[0103] determining a speed reduction change value of the motor speed reduction; determining a to-be-reduced damping value according to a preset speed-damping conversion coefficient and the speed reduction change value; determining a to-be-reduced current according to a preset damping-current conversion coefficient and the to-be-reduced damping value; and reducing the to-be-reduced current applied to the friction layer to reduce the damping value of the damper.

[0104] According to the above embodiment, if the current is reduced, it can be gradually reduced. However, this way has the same problem as the gradually increasing way, that is, the problem of not precise control. Therefore, the embodiments of the present application can be the same as the way of determining the increased current through the speed-damping conversion coefficient and the damping-current conversion coefficient in the above embodiment. In the embodiments of the present application, only the speed-damping conversion coefficient and the damping-current conversion coefficient are added with a negative sign when the to-be-reduced current is determined according to the speed-damping conversion coefficient and the damping-current conversion coefficient, and then multiplied to obtain the to-be-reduced damping value and the to-be-reduced current. Therefore, the current can be reduced according to the to-be-reduced current, and the details are not repeated here.

[0105] To better implement the embodiments of the present application, in an embodiment of the present application, the damper body comprises a spring, and before the motor speed of the motor is obtained, the method further comprises:

[0106] If the washing machine start instruction is obtained, the spring is energized according to an initial energizing current; the first cavity of the washing machine is watered according to the water inlet instruction; a current change value of the initial energizing current is obtained, the current change value representing a weight change value after the first cavity is watered; and if the current change value reaches a preset current change threshold, the watering of the first cavity is stopped.

[0107] In actual process, the water level in the first cavity is usually determined based on the water level sensor, and when the water level reaches the requirement, the water injection is stopped. However, sometimes the water level sensor is damaged, and at this time, the water level sensor cannot sense the water level due to the damage, and the water injection valve cannot be closed. Therefore, in order to solve the problem that the water level sensor is damaged and cannot detect the water level, the embodiment of the application also provides a scheme for determining the water level according to the damper.

[0108] Specifically, according to the above Figure 3 It can be obtained that the damper body further includes a spring 301, because the damper is pressed, the spring 301 will be shortened, and according to the Figure 3 It can be obtained that the damper is used to support the first cavity, and therefore, the deformation of the spring 301 can be detected to determine the weight of the first cavity, so as to realize the detection of the water level. The specific principle is that the size of the first cavity is determined, and therefore, a theoretical weight value can be determined according to the size of the first cavity, when the weight of the water in the first cavity exceeds the theoretical weight value, it can be determined that the water level of the first cavity reaches the requirement, and at this time, the water injection valve can be controlled to be closed. Therefore, the spring 301 of the damper body can be powered at the same time, at this time, the spring 301 can be regarded as a hollow inductor, when the spring 301 is compressed by the gravity, the shorter the hollow inductor is, the smaller the inductive reactance value (the resistance of inductance to current) is, and the direct current resistance is also reduced. In other words, the short hollow inductor will reduce the total impedance of the circuit. If the given power supply voltage is constant, according to Ohm's law, the total impedance of the circuit is reduced, and the total current of the circuit will be increased. Therefore, under the condition that the power supply voltage of the spring is constant, the shorter the spring is, the greater the current in the circuit is. Therefore, the current of the spring 301 can be detected, and if the increase value of the current reaches a certain increase threshold, it indicates that the weight change in the first cavity reaches the requirement, that is, the water level has reached the requirement, and at this time, the water injection valve can be closed.

[0109] In order to better realize the embodiment of the application, in an embodiment of the application, according to the water injection instruction, the first cavity of the washing machine is water injected, including:

[0110] An initial current change value of the initial current is obtained, and the initial current change value represents an initial weight change value of the first cavity after the clothes are put in. If the initial weight change value is greater than or equal to a preset initial weight change threshold, it is prompted that the first cavity is abnormal. If the initial weight change value is less than the initial weight change threshold, the first cavity of the washing machine is water injected according to the water injection instruction.

[0111] However, in some practical cases, the first cavity is not filled with water when the user has not started the washing mode. At this time, it belongs to the stage in which the user puts clothes into the first cavity. However, in this stage, there may be an abnormal heavy object accidentally dropped into the first cavity. At this time, if the overall weight of the first cavity has exceeded the set weight before the water is filled, the water level cannot be detected according to the weight. Therefore, the washing machine is controlled to issue a prompt sound to enable the user to find that the foreign matter is dropped into the first cavity. For example, a buzzer can be installed in the washing machine, and the buzzer is controlled to issue a sound to prompt the user. If the user takes out the foreign matter, the weight returns to normal, and the user starts the washing mode again, at this time, the opening and closing of the water valve can be controlled according to the normal damper detection process of the water level.

[0112] In order to better implement the washing machine control method in the embodiments of the present application, in addition to the washing machine control method, a washing machine control device is also provided in the embodiments of the present application. The device is applied to a washing machine. The washing machine includes a first cavity, a second cavity, a third cavity, a motor, and a damper. The damper includes a damper body and a hanger rod.
