Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a control method and device of a washing machine, equipment and a storage medium. BACKGROUND

[0002] The bottom of the inner tub of the impeller washing machine is provided with a disc-shaped impeller. In the process of washing clothes, the water flow in the inner tub forms a vortex that rotates right and left at times through the rotation of the impeller, thereby driving the clothes to rotate and tumble with the vortex, achieving the removal of dirt from the clothes. However, when there are too many clothes and the water in the tub does not completely submerge the clothes, the upper layer of clothes may not be cleaned or the washing agent such as washing powder may not be dissolved uniformly. This will not only cause the clothes to be left with washing agent, but also affect the washing capacity of the impeller washing machine.

[0003] Currently, in order to solve the above problems, centrifugal spraying water flow is usually used in the washing machine, and a direct speed-up mode from zero to the highest speed is generally adopted. However, the motor continuously maintains a high power consumption state during the entire speed-up process, which also easily causes the motor to overheat and reduces the service life of the motor. SUMMARY

[0004] In view of the above problems, the present application is proposed in order to provide a control method and device of a washing machine, equipment and a storage medium which overcome the above problems or at least partially solve the above problems.

[0009] adjusting the speed of the motor according to the multi-stage speed regulation strategy, so that the water flow of the washing machine overflows from the outer tub cover and sprays into the inner tub.

[0010] Based on the second aspect of the present application, a control device of a washing machine is also provided, the device comprising:

[0011] a water level determination module configured to acquire a set washing water level in response to a washing start instruction;

[0014] a motor adjusting module, configured to adjust the rotating speed of the motor according to the multi-stage speed regulation policy, so that the water flow of the washing machine overflows from the outer bucket cover and sprays to the inner bucket.

[0015] Based on the third aspect of the present application, there is also provided an electronic device, the device comprising:

[0016] one or more processors;

[0017] a memory;

[0018] one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs are configured to perform the method of any one of the above summary.

[0019] Based on the fourth aspect of the present application, there is also provided a computer readable storage medium storing a computer program for use in conjunction with an electronic device, the computer program being executable by a processor to perform the method of any one of the above summary.

[0020] Compared with the prior art, the present application comprises firstly acquiring a set washing water level in response to a washing start instruction, and then determining a target gear corresponding to the set washing water level. Then a multi-stage speed regulation policy of the motor corresponding to the target gear is matched. Finally, the rotating speed of the motor is adjusted according to the multi-stage speed regulation policy, so that the water flow of the washing machine overflows from the outer bucket cover and sprays to the inner bucket. Thus, the multi-stage speed regulation of the motor can be performed according to different water levels in the washing machine, so that the entire speed-up process of the motor can achieve a relatively power-saving effect on the basis of a relatively stable state without overheating. Not only the cleaning effect of the clothes is improved by using the centrifugal spraying water flow, but also the service life of the motor is improved.

[0029] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0030] The following embodiments of the present application are applied to a pulsator washing machine, which comprises an outer tub (a water containing tub), an inner tub (a dewatering tub) embedded in the outer tub, and a motor, wherein the inner tub is used for placing clothes and is coaxially arranged with the outer tub, and an output shaft of the motor is coaxially fixed with the inner tub and drives the inner tub to rotate through the operation of the motor. The bottom of the inner tub is provided with a disc-shaped pulsator with protruding ribs. When the inner tub rotates, the pulsator rotates synchronously, so that the water flow in the inner tub forms vortexes rotating right and left alternately, and the clothes are driven to rotate and tumble along the vortexes, so as to realize the removal of dirt on the clothes.

[0031] Referring to Figure 1 , a control method of a washing machine provided by an embodiment of the present application is shown, which can comprise:

[0032] S101, in response to a washing start instruction, acquiring a set washing water level.

[0033] S102, determining a target gear corresponding to the set washing water level.

[0034] In the embodiment of the present application, in response to the editing operation of the user on the start control (or start switch) of the washing machine, the washing start instruction is obtained, and the washing start instruction is used to start the washing program. After obtaining the washing start instruction, it is detected whether the user edits the water level control (or water level adjustment switch) on the washing machine. If it is detected that the user edits the water level control on the washing machine, the set washing water level set by the user is obtained.

[0035] In another example, in the case that the washing start instruction is obtained and the editing operation of the user on the water level control (or water level adjustment switch) is not detected, the corresponding set washing water level is matched by the weight of the clothes in the inner barrel.

[0036] In another example, in the case that the washing start instruction is obtained and the editing operation of the user on the water level control is not detected, the corresponding set washing water level can also be matched based on the washing mode set by the user. Those skilled in the art can select any one of the above or a combination thereof to determine the set washing water level according to the actual design requirements.

[0037] The target gear is the water level gear corresponding to the set washing water level, wherein the water level gear is used to distinguish the high and low of the water level. The water level gear can be determined in advance according to the water level interval of the washing mode of the washing machine, and each water level interval is taken as a water level gear. Thus, the set washing water level and the water level interval corresponding to each water level gear can be compared, and the target gear corresponding to the set washing water level is determined according to the comparison result.

[0038] S103, matching the multi-stage speed regulation strategy of the motor corresponding to the target gear.

[0039] S104, adjusting the rotating speed of the motor according to the multi-stage speed regulation strategy, so that the water flow overflows from the outer barrel cover and sprays to the inner barrel.

[0040] In the embodiment of the present application, the multi-stage speed regulation strategy can be understood as a strategy for controlling the speed-up of the motor, which is used to speed up the motor in stages, so that the water flow forms a centrifugal spraying water flow to the inner barrel under the rotation of the motor in the gap between the outer barrel and the inner barrel. Since the motor rotating speed of the centrifugal spraying water flow formed by the water level corresponding to different target gears may be different, different multi-stage speed regulation strategies can be set for different water level gears. Thus, the multi-stage speed regulation strategy associated with the target gear can be matched.

[0041] According to the multi-stage speed regulation strategy, the rotating speed of the motor is adjusted, so that the entire speed-up process of the motor can achieve a relatively power-saving effect on the basis of a relatively stable state without overheating.

[0042] To sum up, the control method of the washing machine provided by the embodiment of the present application can comprise the following steps: firstly, a set washing water level is obtained in response to a washing start instruction, and then a target gear corresponding to the set washing water level is determined. According to the multi-stage speed regulation strategy, the rotating speed of the motor is adjusted, so that the entire speed-up process of the motor can achieve a relatively power-saving effect on the basis of a relatively stable state without overheating.

[0043] Referring to Figure 2 , another control method of a washing machine is shown, which can comprise the following steps:

[0044] S201, a set washing water level is obtained in response to a washing start instruction.

[0045] S202, a target gear corresponding to the set washing water level is determined.

[0046] In the embodiment of the present application, a washing start instruction is obtained in response to an editing operation of a start control (or a start switch) on the washing machine, and the washing start instruction is used to start a washing program.

[0047] In another example, when the washing start instruction is obtained and no editing operation of the water level control (or the water level adjustment switch) on the washing machine is detected, a set washing water level corresponding to the weight of the clothes in the inner tub is matched.

[0048] In another example, when the washing start instruction is obtained and no editing operation of the water level control on the washing machine is detected, a set washing water level corresponding to the weight of the clothes in the inner tub is matched. In another example, when the washing start instruction is obtained and no editing operation of the water level control on the washing machine is detected, a set washing water level corresponding to the weight of the clothes in the inner tub is matched. In another example, when the washing start instruction is obtained and no editing operation of the water level control on the washing machine is detected, a set washing water level corresponding to the weight of the clothes in the inner tub is matched.

[0049] The target gear is a water level gear corresponding to the set washing water level, wherein the water level gear is used to distinguish the high and low of the water level. The water level gears can be determined according to the water level intervals in the washing mode of the washing machine in advance, and each water level interval is taken as a water level gear. Thus, the set washing water level can be compared with the water level intervals corresponding to each water level gear, and the target gear corresponding to the set washing water level is determined according to the comparison result, wherein the water level gears include at least two.

[0050] In an example, when the water level gears are two, the water level gears can include a first gear and a second gear. When the water level gears are three, the water level gears can include a first gear, a second gear and a third gear. The water level corresponding to the first gear is lower than the water level corresponding to the second gear, and the water level corresponding to the second gear is lower than the water level corresponding to the third gear. The number of water level gears can be determined according to actual design requirements by those skilled in the art, which is not limited here.

[0051] S203, match the target gear with the preset strategy mapping relationship to determine the multi-stage speed regulation strategy corresponding to the target gear, wherein the multi-stage speed regulation strategy includes a first speed regulation rule and a second speed regulation rule.

[0052] In the embodiment of the application, the multi-stage speed regulation strategy can be understood as a strategy for controlling the speed-up of the motor, which is used to speed up the motor in stages so that the water flow forms a centrifugal spray water flow that sprays the inner tub under the rotation of the motor in the gap between the outer tub and the inner tub. Since the motor speed of the centrifugal spray water flow formed by the water level corresponding to different target gears may be different, different multi-stage speed regulation strategies can be set for different water level gears, thereby establishing a mapping relationship between different gears and multi-stage speed regulation strategies and determining the strategy mapping relationship. Thus, after the target gear is determined, the target gear is matched with the strategy mapping relationship to determine the multi-stage speed regulation strategy corresponding to the target gear.

[0053] In an example, the multi-stage speed regulation strategy can include at least a first speed regulation rule and a second speed regulation rule. The first speed regulation rule and the second speed regulation rule are executed in sequence, so that the motor speed can be regulated in two stages. In other words, the motor speed regulation process can be divided into a first-stage motor speed regulation process and a second-stage motor speed regulation process.

[0054] In some other embodiments, the multi-stage speed regulation strategy can further include a speed regulation rule for regulating the speed of the motor in three stages, or a speed regulation rule for regulating the speed of the motor in four stages, etc. A person skilled in the art can determine the corresponding number of speed regulation stages according to actual design requirements, and the two stages exemplified do not constitute a limitation on the multi-stage speed regulation strategy.

[0055] S204, regulating the speed of the motor according to the first speed regulation rule, so that the water flow in the washing machine is in a critical spraying state.

[0056] In the embodiments of the present application, the critical spraying state refers to the water flow in the washing machine reaching the top of the outer tub and not overflowing from the outer tub cover. The first speed regulation rule can include a first stage acceleration and a first stage speed to be reached at the end of the first stage speed regulation. In other words, the first stage speed is the final speed of the motor after the first stage speed regulation, and the first stage acceleration is the acceleration of the motor during the first stage speed regulation. When the speed of the motor reaches the first stage speed, the water flow in the washing machine is in a critical spraying state, wherein the critical spraying state refers to the water flow in the washing machine reaching the top of the outer tub and not overflowing from the outer tub cover. As shown in Figure 3 The step S204 can further include the following sub-steps:

[0057] S301, accelerating the motor with a first stage acceleration and detecting the speed of the motor.

[0058] S302, detecting whether the speed of the motor reaches a first stage speed.

[0059] In the embodiments of the present application, when it is detected that the speed of the motor reaches (can be understood as equal to or greater than) the first stage speed, the following step S205 is executed; when it is detected that the speed of the motor does not reach (is less than) the first stage speed, the step S204 is repeatedly executed.

[0060] S303, maintaining the first stage speed for a first stage time length, so that the water flow in the washing machine is in a critical spraying state.

[0061] In the first stage speed regulation of the motor, the speed of the motor can be detected. For example, when it is detected that the speed of the motor reaches the first stage speed, the current speed is maintained for a first stage time length, and the first stage acceleration is low. Therefore, less electric energy can be consumed to make the water between the inner tub and the outer tub fully climb to the critical spraying state under the action of centrifugal force, so that the motor can be in a stable operation state without overheating, and the service life of the motor can be guaranteed.

[0062] In an optional embodiment of the application, when the motor is accelerated by the first-stage acceleration, the operating temperature of the motor can also be detected. If the operating temperature of the motor does not reach a first operating temperature, the first-stage acceleration can be increased to shorten the time for the motor to accelerate to the first-stage rotating speed to a greater extent while the motor is in a stable operating state without overheating. The first operating temperature is a temperature value corresponding to a stable operation of the motor for a long time. The first operating temperature can be determined according to actual test results by those skilled in the art. When the first-stage acceleration is increased, the first-stage acceleration must always be less than the second-stage acceleration, and the difference between the two accelerations must be within a preset difference range. The preset difference range can also be determined according to actual test results.

[0063] S205, adjusting the rotating speed of the motor according to a second speed regulation rule, so that the water flow in the critical spraying state overflows from the outer bucket cover and sprays the inner bucket.

[0064] In the embodiment of the application, the second speed regulation rule can include a second-stage acceleration and a first-stage rotating speed required at the end of the second-stage speed regulation. In other words, the second-stage rotating speed is the final rotating speed of the motor after the second-stage speed regulation, and the second-stage acceleration is the acceleration of the motor during the second-stage speed regulation. Thus, the water flow in the critical spraying state can overflow from the outer bucket cover of the washing machine under the action of the further increased centrifugal force, spray the inner bucket, and sufficiently wash the detergent on the upper layer of clothes in the inner bucket through the sprayed water flow. As shown in FIG. 2, the step S205 can further include the following substeps: Figure 4

[0065] S401, during the second-stage motor speed regulation, accelerating the motor by a second-stage acceleration and detecting the rotating speed of the motor.

[0066] S402, detecting whether the rotating speed of the motor reaches a second-stage rotating speed.

[0067] In the embodiment of the application, when it is detected that the rotating speed of the motor reaches (or is greater than) the second-stage rotating speed, the following step S209 is performed; when it is detected that the rotating speed of the motor does not reach (or is less than) the second-stage rotating speed, the above step S207 is performed.

[0068] S403, maintaining the second-stage rotating speed for a second-stage time length, so that the water flow in the critical spraying state overflows from the outer bucket cover and sprays the inner bucket.

[0069] ​In the motor speed regulation process of the second stage, the motor can be further accelerated by a second stage acceleration, and the rotation speed of the motor can be detected. The second stage acceleration is greater than the first stage acceleration. In the second stage acceleration process of the motor, the higher second stage acceleration is used to concentrate the power-consuming acceleration part in the second stage acceleration process. Thus, the power can be reasonably used, and the motor can be accelerated from zero to the second stage rotation speed with the power saving effect.

[0070] In the acceleration process from the first stage rotation speed to the second stage rotation speed, the water flow of the washing machine overflows from the top of the outer tub (the outer tub cover) under the action of the higher centrifugal force to form a centrifugal spraying water flow towards the inner tub. The second stage duration is a pre-set duration for maintaining the second stage rotation speed. In the case that the rotation speed of the motor reaches the second stage rotation speed, the second stage rotation speed needs to be maintained for the second stage duration. Thus, the spraying duration can be ensured to determine the spraying effect, and the problems of uneven detergent dissolution and incomplete cleaning can be avoided. Meanwhile, the problem of water flow spouting out of the machine body caused by long-time maintenance of high rotation speed under the condition of high water level can also be avoided.

[0071] In an optional embodiment, in the case that the water level gears include a first gear and a second gear, the water level of the first gear is lower than that of the second gear. Correspondingly, the lower the water level is, the higher rotation speed is needed to make the water flow of the washing machine reach the critical spraying state. That is, the first stage rotation speed corresponding to the first gear is greater than or equal to the first stage rotation speed corresponding to the second gear, and the second stage rotation speed corresponding to the first gear is greater than or equal to the second stage rotation speed corresponding to the second gear.

[0072] Table 1: Multi-stage speed regulation strategy corresponding to three water level gears

[0073] First gear Second gear Third gear First stage speed V1 / rpm V1.1 V1.2 V1.3 Second stage speed V2 / rpm V2.1 V2.2 V2.3 Set maintenance time t / s t1 t2 t3

[0074] As shown in Table 1, in the case that the water level gears include a first gear, a second gear and a third gear, the first stage rotation speed V1.1 corresponding to the first gear is greater than or equal to the first stage rotation speed V1.2 corresponding to the second gear, and the first stage rotation speed V1.2 corresponding to the second gear is greater than or equal to the first stage rotation speed V1.3 corresponding to the third gear. Moreover, the second stage rotation speed V2.1 corresponding to the first gear is greater than or equal to the second stage rotation speed V2.2 corresponding to the second gear, and the second stage rotation speed V2.2 corresponding to the second gear is greater than or equal to the second stage rotation speed V2.3 corresponding to the third gear.

[0075] The first stage speed, the second stage speed and the set maintaining time corresponding to different water level positions can be different, and the first stage acceleration is less than the second stage acceleration. The set maintaining time t is the cumulative time of the time length of the motor from zero speed to the second stage speed and the second stage preset time length. For example, the set maintaining time can be between 40S to 60S. The first stage speed V1 can be 80-150rpm, the second stage speed can be 130-200rpm, the first stage acceleration can be 2-5m\s 2 , and the second stage acceleration can be 6-10m\s 2 .

[0076] In addition, the first stage time length corresponding to different water level positions can be different, and the second stage preset time length corresponding to different water level positions can also be different, so that the problem of poor spraying effect caused by too short maintaining time of the second stage speed in the case of low water level can be avoided, and the problem of water flow spattering caused by long time maintaining high speed in the case of high water level can also be avoided, which causes the water flow to flow out of the machine body.

[0077] S206, stop the rotation of the motor.

[0078] S207, after a third preset time length, execute the set washing mode.

[0079] In the embodiment of the application, in the case that the speed of the motor reaches the second stage speed and the time length of maintaining the second stage speed reaches the second stage time length, it is determined that the second stage motor speed regulation process is completed. Thus, the rotation of the motor can be stopped (i.e. the speed of the motor is slowly reduced to zero). The third preset time length is used to reserve the heat dissipation time after high speed rotation of the motor, so that the service life of the motor can be prolonged.

[0080] The set washing mode can be understood as the washing mode set by the user, for example, it can include fast washing, mixed washing, large piece washing, etc. Thus, through the multi-stage speed regulation of the motor, the washing agent can be fully dissolved in water, and the cleaning effect of the clothes can be improved. After the set washing mode is run, the operation of the washing machine is stopped, and it is determined that the clothes washing is completed.

[0081] To sum up, the embodiment of the application discloses a control method of a washing machine, which can comprise the following steps: firstly, acquiring a set washing water level in response to a washing starting instruction; then, determining a target gear corresponding to the set washing water level; then, matching a multi-stage speed regulation strategy of a motor corresponding to the target gear; and finally, adjusting the rotating speed of the motor according to the multi-stage speed regulation strategy, so that the water flow of the washing machine overflows from the outer bucket cover and sprays the inner bucket. Therefore, the multi-stage speed regulation of the motor can be performed according to different water levels in the washing machine, so that the entire speed-up process of the motor can achieve the effect of relatively saving electricity on the basis of the relatively stable state without overheating, the centrifugal spraying water flow is used to improve the cleaning effect of clothes, and the service life of the motor is improved.
