Description

Technical Field

[0001] This application belongs to the field of washing machine technology, and particularly relates to a control method, device, electronic equipment and storage medium for a washing machine. Background Technology

[0002] Modern washing machines, after completing the washing cycle, will enter the spin-drying cycle. In the spin-drying cycle, the inner drum rotates at high speed to remove the water contained in the clothes and dry them.

[0003] However, when clothes have a strong water absorption capacity, the moisture content inside the clothes may still be high when the inner drum enters the spin-drying stage. This can lead to the washing machine spinning with water on the clothes, causing the spin-drying motor to consume too much power, resulting in excessive electricity consumption and affecting the lifespan of the motor. Secondly, spinning with water on the clothes can also lead to poor spin-drying effect, excessive moisture content in the clothes, and residual foam, which can also affect the spin-drying effect of the washing machine. Summary of the Invention

[0004] This application provides a control method, device, electronic device, and storage medium for a washing machine to solve the problem that existing washing machines tend to spin-dry clothes with water remaining when washing clothes with high water absorption capacity.

[0005] This application provides a control method for a washing machine, the washing machine including a drain pump, an inner drum, and an outer drum, the method including:

[0006] Obtain the first mass of the load in the inner drum before the start of the washing program;

[0007] After the washing program is completed, the drain pump is controlled to draw the solution in the outer cylinder until the liquid level in the outer cylinder drops to the preset level, and the second mass of the load is obtained;

[0008] If the difference between the first mass and the second mass is greater than the first threshold, then the inner cylinder is controlled to rotate at a first speed and the drainage pump is controlled to drain water, and the third mass of the load is obtained.

[0009] If the difference between the third mass and the first mass is less than or equal to the first threshold, the inner cylinder is controlled to perform a dehydration process at a second rotation speed.

[0010] The second rotational speed is greater than the first rotational speed.

[0011] Optionally, controlling the inner cylinder to perform the dehydration process at a second rotational speed includes:

[0012] The second rotational speed is determined based on the third mass and the position of the first center of mass of the inner cylinder when the load is the third mass;

[0013] The inner cylinder is controlled to run at the second rotation speed for a first preset time, and the drain pump is controlled to drain water.

[0014] Optionally, determining the second rotational speed based on the third mass and the first center of mass position of the inner cylinder when the load is the third mass includes:

[0015] Obtain the centroid offset between the second centroid position and the first centroid position of the inner cylinder when the load is the first mass;

[0016] If the centroid offset is greater than the second threshold, the inner cylinder is controlled to rotate at a third speed to adjust the first centroid position and obtain the adjusted first centroid position until the centroid offset is less than or equal to the second threshold.

[0017] The second rotational speed is determined based on the adjusted first centroid position and the third mass;

[0018] The third rotational speed is less than the second rotational speed.

[0019] Optionally, determining the second rotational speed based on the third mass and the first center of mass position of the inner cylinder when the load is the third mass includes:

[0020] The initial rotational speed of the inner cylinder is determined based on the third mass;

[0021] The deceleration level of the inner cylinder is determined based on the centroid offset between the second centroid position and the first centroid position of the inner cylinder when the load is the first mass.

[0022] The initial rotational speed is reduced according to the reduction level to obtain the second rotational speed.

[0023] Optionally, controlling the inner cylinder to operate at the second rotational speed includes:

[0024] The inner cylinder is controlled to accelerate to the second rotational speed at a preset acceleration, and then operates at the second rotational speed.

[0025] Optionally, after controlling the inner cylinder to operate at the second rotational speed, the method includes:

[0026] Monitor the centroid offset between the first centroid position of the inner cylinder and the second centroid position of the inner cylinder when the load is the first mass;

[0027] If the centroid offset is greater than the fourth threshold, the rotation speed of the inner cylinder is controlled to decrease by a preset value based on the second rotation speed until the centroid offset is less than or equal to the fourth threshold.

[0028] Optionally, controlling the inner cylinder to rotate at a first rotational speed and controlling the drain pump to drain water includes:

[0029] The drain pump is shut off and the inner cylinder rotates at a first speed for a second preset time to squeeze out a portion of the solution absorbed by the load.

[0030] The inner cylinder is kept stationary while the drainage pump is activated for a third preset time to remove the solution from the outer cylinder.

[0031] This application embodiment also provides a control device for a washing machine, the device comprising:

[0032] The mass acquisition module is configured to acquire the first mass of the load in the inner drum before the start of the washing program;

[0033] The first drainage module is configured to control the drainage pump to draw the solution in the outer cylinder after the washing program is completed, until the liquid level in the outer cylinder drops to a preset level, and obtain the second mass of the load;

[0034] The second drainage module is configured to control the inner cylinder to rotate at a first speed and control the drainage pump to drain water if the difference between the first mass and the second mass is greater than a first threshold, thereby obtaining the third mass of the load.

[0035] The control module is configured to control the inner cylinder to perform a dehydration process at a second rotation speed if the difference between the third mass and the first mass is less than or equal to a first threshold.

[0036] This application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the washing machine control method described above.

[0037] This application embodiment also provides a storage medium storing control instructions, which, when executed by a processor, implement the washing machine control method described above.

[0038] The washing machine control method provided in this application detects the difference in load mass before and after washing. If the difference between the load mass after washing and the load mass before washing is greater than a first threshold, indicating a large difference, it means the load has a high water content. By controlling the rotation of the inner drum and the drainage pump, the water content of the clothes is further reduced. Since the first rotation speed of the inner drum is lower than the second rotation speed during the spin cycle, the rotation speed of the inner drum is relatively low, and the centrifugal force is relatively small. Under the action of gravity, the squeezed water flows more easily to the bottom of the drum, meeting the need for pre-spinning the load with a small discharge volume before the spin cycle, and also saving the operating cost of the washing machine. If the difference between the load mass after washing and the load mass before washing is less than or equal to the first threshold, it means the load water content is within the normal range, and the machine directly enters the spin cycle for spin drying. In other words, by controlling the water content of the load before entering the spin cycle, the washing machine avoids spin drying with water, thus improving the spin drying effect.

[0048] This application provides a control method, device, electronic device, and storage medium for a washing machine to solve the problem that existing washing machines tend to spin-dry clothes with water remaining when washing clothes with high water absorption capacity. The following description is in conjunction with the accompanying drawings.

[0049] For the washing machine control method provided in this application's embodiments, please refer to [link / reference needed]. Figure 5 , Figure 5 This is a schematic diagram of the structure of a washing machine 1 provided in an embodiment of this application. The washing machine 1 includes a drain pump 13, an inner drum 11, and an outer drum 12. Please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a usage scenario diagram of the control method for washing machine 1 provided in the embodiments of this application. Figure 2 This is a flowchart of a control method for a washing machine 1 provided in an embodiment of this application. The control method for the washing machine 1 includes the following steps:

[0050] Step S101: Obtain the first mass of the load in the inner drum 11 before the washing program starts;

[0051] Step S102: After the washing program is completed, control the drain pump 13 to draw the solution in the outer cylinder 12 until the liquid level in the outer cylinder 12 drops to the preset liquid level and the second mass of the load is obtained;

[0052] Step S103: If the difference between the first mass and the second mass is greater than the first threshold, control the inner cylinder 11 to rotate at the first speed and control the drainage pump 13 to drain water, and obtain the third mass of the load.

[0053] Step S104: If the difference between the third mass and the first mass is less than or equal to the first threshold, then control the inner cylinder 11 to perform the dehydration process at the second rotation speed; wherein the second rotation speed is greater than the first rotation speed.

[0054] The control method for the washing machine 1 provided in this application embodiment detects the difference in load mass before and after washing. If the difference between the load mass after washing and the load mass before washing is greater than a first threshold, indicating a large difference, it means the load has a high water content. By controlling the rotation of the inner drum 11 and the drainage pump 13, the water content of the clothes is further reduced. Since the first rotation speed of the inner drum 11 is lower than the second rotation speed during spin-drying, the rotation speed of the inner drum 11 is relatively low, and the centrifugal force is relatively small. Under the action of gravity, the squeezed water flows more easily to the bottom of the drum, meeting the need for pre-spinning the load with a small discharge volume before the spin-drying program. At the same time, it also saves the operating cost of the washing machine 1. If the difference between the load mass after washing and the load mass before washing is less than or equal to the first threshold, it means the load water content is within the normal range. At this time, the machine directly enters the spin-drying stage for spin-drying. That is, by controlling the water content of the load before entering the spin-drying program, the washing machine 1 avoids spin-drying with water, thus improving the spin-drying effect.

[0055] Optionally, step S104, controlling the inner cylinder 11 to perform the dehydration process at a second rotation speed, includes:

[0056] Step S1041: Determine the second rotational speed based on the third mass and the first center of mass position of the inner cylinder 11 when the load is the third mass;

[0057] Step S1042: Control the inner cylinder 11 to run at the second speed for a first preset time, and control the drain pump 13 to drain water.

[0058] The second rotational speed of the inner cylinder 11 during the dehydration process is determined by the third mass of the load when it enters the dehydration process and the first centroid position of the load at this time. This allows for a more suitable second rotational speed to be matched to the load in the inner cylinder 11 as the rotational speed of the dehydration process. This avoids the situation where the second rotational speed of the dehydration process is a fixed value, which could lead to a large eccentricity of the inner cylinder 11 or even collision with the drum if the mass of the load is too large, or a small mass of the load, which would result in unnecessary energy waste due to a large power consumption driving a small load.

[0059] Optionally, step S1041 determines the second rotational speed based on the third mass and the first center of mass position of the inner cylinder 11 when the load is the third mass, including:

[0060] Step S10411: Obtain the centroid offset between the second centroid position and the first centroid position of the inner cylinder 11 when the load is the first mass;

[0061] Step S10412: If the center of mass offset is greater than the second threshold, control the inner cylinder 11 to rotate at the third speed to adjust the first center of mass position and obtain the adjusted first center of mass position until the center of mass offset is less than or equal to the second threshold.

[0062] Step S10413: Determine the second rotational speed based on the adjusted first centroid position and the third mass; wherein the third rotational speed is less than the second rotational speed.

[0063] That is, when performing step S1041 to determine the second rotation speed based on the third mass and the first centroid position of the inner drum 11 when the load is the third mass, the centroid offset of the inner drum 11 before and after the washing program is first detected. If the centroid offset is large, the centroid of the inner drum 11 is adjusted until the centroid offset is less than or equal to the second threshold. Then, the second rotation speed is determined based on the adjusted first centroid position and the third mass that meet the centroid offset requirement. If the centroid offset directly meets the requirement of being less than or equal to the second threshold, the second rotation speed is directly determined based on the current first centroid position and the third mass, without the need to adjust the current first centroid position.

[0064] Since adjusting the first centroid position of the inner cylinder 11 only requires appropriate agitation of the load and does not require a large rotation speed, the third rotation speed here is less than the second rotation speed, thus achieving the function of adjusting the first centroid position of the inner cylinder 11 with less power consumption.

[0065] As an alternative implementation, step S10411 can also be: obtaining the centroid offset between the first centroid position and the standard centroid position, wherein the standard centroid position can be the position corresponding to the centroid of the inner cylinder 11 when the inner cylinder 11 is empty.

[0066] Optionally, step S1041: Determine the second rotational speed based on the third mass and the first center of mass position of the inner cylinder 11 when the load is the third mass, including:

[0067] Step S10414: Determine the initial rotational speed of the inner cylinder 11 based on the third mass;

[0068] Step S10415: Determine the deceleration level of the inner cylinder 11 based on the centroid offset between the second centroid position and the first centroid position of the inner cylinder 11 when the load is the first mass;

[0069] Step S10416: Reduce the initial speed according to the speed reduction level to obtain the second speed.

[0070] The second rotational speed during the spin-drying cycle of the inner drum 11 is determined not only by the initial rotational speed corresponding to the third mass when the load enters the spin-drying cycle, but also by adaptively reducing the initial rotational speed based on the centroid offset of the inner drum 11 before and after the washing cycle. This results in a second rotational speed that better matches the current load condition of the inner drum 11, reducing the probability of large eccentricity or even collision of the inner drum 11. Each speed reduction level corresponds to a speed reduction threshold. The larger the centroid offset, the higher the speed reduction level, i.e., the larger the speed reduction threshold; the smaller the centroid offset, the smaller the speed reduction level, i.e., the smaller the speed reduction threshold. It should be noted that the third mass is directly proportional to the initial rotational speed; that is, the larger the third mass, the larger the initial rotational speed. Therefore, the larger the third mass of the inner drum 11 and the smaller the centroid offset, the larger the second rotational speed; conversely, the smaller the third mass of the inner drum 11 and the larger the centroid offset, the smaller the second rotational speed. Further examples of the initial rotational speed and speed reduction levels are not provided here.

[0071] Optionally, controlling the inner cylinder 11 to operate at a second rotational speed in step S1042 includes:

[0072] Step S10421: Control the inner cylinder 11 to accelerate to a second rotational speed with a preset acceleration, and operate at the second rotational speed. In some examples, the preset acceleration can be from 10 r / s to 15 r / s, preferably 12 r / s. In some examples, the second rotational speed can be from 800 rpm to 1000 rpm, for example, 800 rpm, 900 rpm, 1000 rpm, etc.

[0073] The existing preset acceleration is usually 20 r / s, that is, by extending the acceleration time of the inner cylinder 11 by a lower preset acceleration, the moisture in the load is further removed before the inner cylinder 11 performs high dehydration at the second speed, thereby reducing the mass of the load and improving the conversion rate of the work done by the dehydration motor.

[0074] Optionally, the washing machine 1 includes a turbidity sensor and a water inlet valve. After controlling the inner drum 11 to run at a second rotation speed in step S1042, the method includes:

[0075] Step S10422: Monitor the turbidity value in the solution using a turbidity sensor;

[0076] Step S10423: If the turbidity value is greater than the third threshold, control the water inlet valve to inject a preset volume of water into the inner cylinder 11 until the turbidity value is less than or equal to the third threshold.

[0077] By monitoring the turbidity value of the solution during the spin-drying process, the cleaning effect on the load is further ensured, preventing the detergent content in the load from remaining high due to inadequate cleaning. It should be noted that the preset volume usually corresponds to a small volume value, so even if water is added to the inner drum 11, it will not significantly affect the center of gravity of the inner drum 11; the effect here is negligible. Of course, to avoid accidents, an alarm device can be set here. When the liquid level in the inner drum 11 exceeds the set threshold, the machine will stop and an alarm will sound, preventing overflow or short circuit problems caused by water adding to the inner drum 11 exceeding the set threshold.

[0078] Optionally, after controlling the inner cylinder 11 to operate at the second rotational speed in step S1042, the method includes:

[0079] Step S10424: Monitor the centroid offset between the first centroid position of the inner cylinder 11 and the second centroid position of the inner cylinder 11 when the load is the first mass;

[0080] Step S10425: If the center of mass offset is greater than the fourth threshold, the rotation speed of the inner cylinder 11 is reduced by a preset value based on the second rotation speed until the center of mass offset is less than or equal to the fourth threshold.

[0081] During the dehydration process of the inner cylinder 11, the position of the center of mass of the inner cylinder 11 is still monitored. The monitoring time is not further limited. It can be real-time monitoring or monitoring at preset intervals. The center of mass offset is judged. When the center of mass offset is greater than the fourth threshold, it means that the center of mass of the inner cylinder 11 is offset by a large value. Therefore, the rotation speed of the inner cylinder 11 is reduced by a preset value to avoid the inner cylinder 11 from hitting the cylinder. After the inner cylinder 11 runs at a lower speed for a certain period of time, the load is agitated by the inner cylinder 11, which changes the position of the load in the inner cylinder 11 and thus changes the position of the center of mass of the inner cylinder 11. Therefore, the center of mass offset can be gradually reduced until it is less than or equal to the fourth threshold. The fourth threshold is not further limited here, nor is the relationship between the fourth threshold and the second threshold further limited here.

[0082] Steps S10424 and S10425 can be executed after step S10423 to ensure that the center of mass offset of the inner cylinder 11 is within the allowable range after water is added to the inner cylinder 11, and to prevent the center of mass offset of the inner cylinder 11 from being too large or from hitting the barrel.

[0083] Optionally, step S103, which involves controlling the inner cylinder 11 to rotate at a first rotational speed and controlling the drain pump 13 to drain water, includes:

[0084] Step S1031: Control the drain pump 13 to shut down and the inner cylinder 11 to rotate at the first speed for the second preset time to squeeze out part of the solution absorbed by the load;

[0085] Step S1032: Control the inner cylinder 11 to remain stationary and start the drainage pump 13 for a third preset time to drain the solution in the outer cylinder 12.

[0086] Since the inner cylinder 11 rotates at a low speed to squeeze out some of the water in the load, the amount of water squeezed out is relatively small. If the drain pump 13 is turned on at the same time as the inner cylinder 11 rotates, the drain pump 13 is prone to dry suction due to the small amount of solution that can be drained. Therefore, the drain pump 13 and the inner cylinder 11 are controlled to work alternately. After the inner cylinder 11 rotates for a second preset time, the drain pump 13 is turned on to drain water. After the drain pump 13 is turned off, the inner cylinder 11 is turned on again. This ensures that the drain pump 13 is turned on only after a certain amount of water has been squeezed out, reducing the probability of the drain pump 13 dry suction.

[0087] In some examples, the first rotation speed can be between 200 rpm and 240 rpm. Preferably, the first rotation speed can be 220 rpm. At this speed, the small displacement water squeezing requirement of the inner drum 11 for the load can be met well. If the speed is too low, water cannot be squeezed effectively. If the speed is too high, the dehydration resonance point of the drum washing machine 1 will be easily reached. If the drum stays for a long time, the risk of displacement will increase.

[0088] In some examples, the second preset duration can be 1 to 2 minutes, for example, 1 minute, 1.5 minutes, 2 minutes, etc. In some examples, the third preset duration can be 1 to 2 minutes, for example, 1 minute, 1.5 minutes, 2 minutes, etc.

[0089] Furthermore, the rotation directions of the inner cylinder 11 can be opposite in two adjacent rotations to further improve the dewatering efficiency.

[0090] Optionally, the control method of the washing machine 1 provided in the embodiments of this application also includes a washing program. After the inner drum 11 rotates for a preset time to complete the washing action, it waits for a preset interval before turning on the drain pump 13 to drain water. In some examples, the preset interval can be 30s to 2min, such as 30s, 60s, 120s, etc.

[0091] By waiting for a preset interval, the water in the load is ensured to flow fully to the bottom of the inner cylinder 11, thereby further improving the drainage efficiency of the drainage pump 13.

[0092] This application also provides a control device for a washing machine 1. Please refer to [link / reference]. Figure 3 , Figure 3This is a schematic diagram of the control device for a washing machine 1 provided in an embodiment of this application. The device includes a mass acquisition module 2, a first drainage module 3, a second drainage module 4, and a control module 5. The mass acquisition module 2 is configured to acquire a first mass of the load in the inner drum 11 before the start of the washing program; the first drainage module 3 is configured to control the drain pump 13 to draw the solution in the outer drum 12 after the washing program ends, until the liquid level in the outer drum 12 drops to a preset liquid level, and obtain a second mass of the load; the second drainage module 4 is configured to control the inner drum 11 to rotate at a first speed and control the drain pump 13 to drain water if the difference between the first mass and the second mass is greater than a first threshold, and obtain a third mass of the load; the control module 5 is configured to control the inner drum 11 to perform a spin-drying program at a second speed if the difference between the third mass and the first mass is less than or equal to the first threshold.

[0093] Specifically, steps S101, S102, S103, and S104 are executed sequentially by the quality acquisition module 2, the first drainage module 3, the second drainage module 4, and the control module 5 to detect the difference in load mass before and after washing. If the difference between the load mass after washing and the load mass before washing is greater than a first threshold, indicating a large difference, it means that the load has a high water content. By controlling the rotation of the inner drum 11 and the drainage pump 13 to drain water, the water content of the clothes is further reduced. Since the first rotation speed of the inner drum 11 is lower than the second rotation speed during the spin cycle, the rotation speed of the inner drum 11 is relatively low, and the centrifugal force is relatively small, which is more conducive to the discharge of water from the surface of the load. This meets the requirement of pre-spinning the load with a small amount of water before the spin cycle, and also saves the operating cost of the washing machine 1. If the difference between the load mass after washing and the load mass before washing is less than or equal to the first threshold, it means that the load water content is within the normal range, and the spin cycle is directly entered. That is, by controlling the moisture content of the load before entering the dehydration program, the washing machine 1 can avoid the phenomenon of dehydration with water, thereby improving the dehydration effect.
