Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of washing machines, and specifically to a washing machine control method, device, electronic device, and computer-readable storage medium. Background Art

[0002] The working principle of a washing machine is to beat the clothes by the operation of the inner drum, so as to separate the stains from the clothes and achieve the purpose of cleaning the clothes. Since the washing machine is always in motion, the clothes in the inner drum will be offset to a certain extent relative to the rotating axis. If the washing machine is dehydrated at high speed with a large eccentricity, problems such as hitting the drum, shifting, and vibration may occur, affecting the user's washing process.

[0003] In the prior art, the maximum eccentricity capacity value of the washing machine can be set in advance, and when the eccentricity value of the washing machine reaches the maximum value, corresponding processing can be performed; alternatively, a position sensor such as a Hall sensor can be set in the washing machine to detect the movement path of the inner drum of the washing machine, so as to monitor the eccentricity in real time and perform corresponding processing.

[0004] However, in actual applications, the maximum eccentricity capacity value set in advance cannot be adapted to all washing machine models, and when the anti-eccentricity capacity of individual machines is abnormal, it cannot be identified, resulting in a drum collision phenomenon; in addition, the solution of using a position sensor to detect the movement path of the inner drum in real time to avoid the occurrence of a drum collision phenomenon requires high computing power and the calculation process is relatively complicated.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0067] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the above features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0068] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0069] First, the terms involved in this application are explained:

[0070] Inner drum: The inner drum is the part that comes into direct contact with the clothes. It rotates to agitate the clothes, thereby achieving washing and rinsing.

[0071] Outer drum: The outer drum surrounds the inner drum and is primarily used to contain water and detergent and to ensure that water does not leak into other parts of the washing machine.

[0072] The embodiments of the present application provide a washing machine control method, device, electronic device, and computer-readable storage medium. Specifically, the embodiments of the present application provide a washing machine control device applicable to the washing machine control method, the washing machine control device includes a washing machine and a main control device of the washing machine, and the washing machine can be a pulsator washing machine, a drum washing machine, an agitator washing machine, a jet washing machine, or other washing machine capable of washing clothes.

[0073] In the prior art, during the operation of the washing machine, the clothes in the inner drum will be greatly displaced from the rotating axis of the inner drum due to the rotation of the inner drum.

[0074] For example, in a drum washing machine, the drum rotates continuously, causing the clothes to tumble continuously under the action of gravity. The tumbling of the clothes causes friction and beating between the clothes, thereby achieving the purpose of cleaning the clothes. However, during the tumbling of the clothes, the clothes in the drum will continuously shift, resulting in a large eccentricity (i.e., the center of gravity of the clothes in the inner drum deviates from the rotation axis). In this case, if high-speed rotation is still used for washing or dehydration, the inner and outer drums of the washing machine may collide, affecting the user's washing process, and even causing the washing machine to shift, vibrate, or be damaged.

[0075] At present, in order to prevent the washing machine from having problems such as hitting the drum, shifting, vibrating, and being damaged, the maximum eccentricity capacity value of the washing machine can be set in advance, or the movement path of the inner drum can be detected in real time through a position sensor to avoid hitting the drum.

[0076] However, the maximum eccentricity value set in advance is not applicable to all different models of washing machines, and detecting the movement path of the inner drum through a position sensor requires higher computing power.

[0077] Therefore, the washing machine control method in the prior art has the technical problem of being unable to timely and effectively avoid the washing machine from hitting the drum, shifting, vibrating, being damaged, etc. due to the deviation of clothes.

[0078] The embodiment of the present application provides a washing machine control method, device, electronic device and computer-readable storage medium. The method adopts the following steps: determining a first position and a second position, wherein the first position is the current position of the inner drum and the second position is the current position of the outer drum; determining a first anti-eccentricity value according to the first position and the second position, wherein the first anti-eccentricity value is used to characterize the ability of the washing machine to resist unbalanced loads during operation; determining a dehydration coefficient of the washing machine, wherein the dehydration coefficient is used to adjust the speed of the washing machine during the dehydration operation phase; and determining the speed of the washing machine according to the first anti-eccentricity value and the dehydration coefficient.

[0079] In summary, the washing machine control method in the embodiment of the present application can accurately judge the eccentricity of the washing machine according to the positions of the inner drum and the outer drum, and adjust the speed of the washing machine during the dehydration operation stage according to the eccentricity, thereby achieving the technical effect of avoiding collision between the inner drum and the outer drum of the washing machine.

[0080] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0081] See also Figure 1 , Figure 1The following is a scene diagram of the washing machine control method provided in the embodiment of the present application. The washing machine control system may include a washing machine 100 and a main control device 200. The washing machine 100 and the main control device 200 may be connected to each other in any manner, including but not limited to signal communication through electronic circuits, communication through wireless signals, and the wireless signals may be computer network communications of the TCP / IP Protocol Suite (TCP / IP) and the User Datagram Protocol (UDP). The washing machine 100 may receive control signals from a remote control or a control panel, and the washing machine 100 may also receive command information sent by the main control device 200. The washing machine 100 may perform corresponding operations according to the corresponding command information.

[0082] In the embodiment of the present application, the washing machine 100 includes but is not limited to a drum washing machine, a pulsator washing machine, an agitator washing machine, a jet washing machine and other laundry equipment capable of washing clothes.

[0083] Those skilled in the art will understand that Figure 1 The application environment shown in the figure is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or less washing machines as shown in Figure 1 Only one washing machine is shown in the figure, and the specific details are not limited here.

[0084] In addition, if Figure 1 As shown, the main control device 200 may include any hardware device capable of data processing and instruction sending, such as a CPU or a single-chip microcomputer embedded in the washing machine, and the specific details are not limited here.

[0085] It should be noted that Figure 1 The scenario diagram of the washing machine control system shown is only an example. The washing machine control system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the evolution of the washing machine control system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0086] For details, please refer to Figure 2 , Figure 2 : is a schematic diagram of a scenario in which a washing machine according to an embodiment of the present application executes the washing machine control method, wherein the specific execution process of the washing machine executing the washing machine control method is as follows:

[0087] S201: Determine a first position and a second position.

[0088] In the embodiment of the present application, the first position is the current position of the inner cylinder, and the second position is the current position of the outer cylinder. Figure 3 The structural schematic diagram of the washing machine shown in the figure, the washing machine includes a housing, an inner drum and an outer drum, and also includes: a photosensitive device transmitting end (first position sensor), a photosensitive device receiving end (second position sensor), a microcontroller, and a circuit for the microcontroller to communicate with the position sensor. A first position sensor is provided on the inner drum of the washing machine, and a second position sensor is provided on the outer drum of the washing machine. The first position of the inner drum can be obtained in real time or at a predetermined time through the first position sensor; correspondingly, the second position of the outer drum can be obtained in real time or at a predetermined time through the second position sensor.

[0089] Optionally, the washing machine control method provided in the embodiment of the present application further includes: obtaining a first position of a first position sensor, the first position sensor being arranged on the inner drum; and obtaining a second position of a second position sensor, the second position sensor being arranged on the outer drum.

[0090] In the embodiment of the present application, the first position sensor and the second position sensor can be various types of position sensors, such as photosensitive devices. Figure 3 As shown, the transmitting end of the photosensitive device can be arranged at the inner end of the outer tube, and the receiving end of the photosensitive device can be arranged at the outer end of the inner tube.

[0091] It should be noted that the embodiments of the present application only use a photosensitive device as an example. The photosensitive device has a distance sensing function and can judge the distance between the receiver and the transmitter by the reflection of light. In addition to the photosensitive device, other types of position sensors can also be used, such as: magnetic encoders, Hall sensors, ultrasonic sensors, etc., which are not specifically limited in the embodiments of the present application.

[0092] In addition, in the embodiment of the present application, a plurality of photosensitive devices or other position sensors can be placed on a washing machine. The receiving end of the photosensitive device can be connected to the chip port through a receiving circuit to transmit data to the chip for calculation.

[0093] Optionally, the positions of the inner cylinder and the outer cylinder can be determined by a photosensitive device or other position sensors, thereby determining the distance between the inner cylinder and the outer cylinder, without the need to obtain the movement trajectory of the inner cylinder or the outer cylinder in real time, thus avoiding a large number of complex calculation processes.

[0094] S202: Determine a first anti-eccentricity value according to the first position and the second position.

[0095] In the embodiment of the present application, the first anti-eccentricity value is used to characterize the ability of the washing machine to resist unbalanced load during operation.

[0096] Optionally, the washing machine control method provided in the embodiment of the present application also includes: determining a first spacing according to the first position and the second position, and a first eccentricity value corresponding to the first spacing; and determining a first anti-eccentricity value according to the first spacing and the first eccentricity value.

[0097] In the embodiment of the present application, during the operation of the washing machine, the first distance between the inner drum and the outer drum can be determined according to the first position of the inner drum and the second position of the outer drum obtained. m j , and further determine the first eccentricity value according to the first spacing Mj .

[0098] It should be noted that the eccentricity value is related to the weight of the clothes. Clothes of different weights scattered or gathered in different positions in the drum will cause the inner drum to deviate from the center value, that is, the eccentricity value. The eccentricity value can be calculated by the change in the current under the running state of the motor to calculate the speed change, and the eccentricity value is corresponding to the change in speed within a cycle. Because of the eccentricity, the inner drum will tilt closer to the outer drum, and mj corresponds to the distance between the outer measurement of the inner drum and the inner measurement of the outer drum after tilting.

[0099] Optionally, the first spacing and the first eccentricity value can be calculated based on the installation position of the first position sensor on the inner cylinder, the installation position of the second position sensor on the outer cylinder, the first position reported by the first position sensor, and the second position reported by the second position sensor.

[0100] It should be noted that the first spacing is the spacing between the current inner cylinder and the outer cylinder, and the first eccentricity value is used to represent the degree to which the center of gravity of the current inner cylinder deviates from the rotation axis.

[0101] In the embodiment of the present application, after determining the first spacing and the first eccentricity value, the first anti-eccentricity value Gj can be further calculated according to the first spacing and the first eccentricity value, that is, the anti-eccentricity value can be calculated through the position information obtained by the position sensor.

[0102] It should be noted that the first anti-eccentricity value can be used to characterize the ability of the washing machine to resist the unbalanced load under the current unbalanced load. After the washing machine has been running for a period of time, the center of gravity of the clothes shifts with the operation of the washing machine, and the clothes with the center of gravity shifted are unbalanced loads.

[0103] S203: Determine the dehydration coefficient of the washing machine.

[0104] In an embodiment of the present application, the dehydration coefficient can be determined before the washing machine leaves the factory or before it is officially used, and the obtained dehydration coefficient is stored in the microcontroller (MCU) of the washing machine.

[0105] Optionally, the washing machine can control its own rotation speed according to the dehydration coefficient during the dehydration operation phase, thereby preventing the inner drum from colliding with the outer drum and minimizing the vibration and displacement amplitude of the washing machine.

[0106] It should be noted that the dehydration coefficient is used to adjust the speed of the washing machine during the dehydration operation phase.

[0107] Optionally, the washing machine control method provided in the embodiment of the present application further includes: determining a second anti-eccentricity value and a third anti-eccentricity value of the washing machine; and determining a dehydration coefficient according to the second anti-eccentricity value and the third anti-eccentricity value.

[0108] In the embodiment of the present application, the second anti-eccentricity value is used to characterize the maximum ability of the washing machine to resist unbalanced load during operation, and the load corresponding to the second anti-eccentricity value may be greater than the maximum load of the inner drum of the washing machine (for example: the maximum load is 5kg, and the load corresponding to the second anti-eccentricity value is 6kg); the third anti-eccentricity value is used to characterize the resistance of the washing machine under the maximum unbalanced load, that is, the ability of the washing machine to resist the unbalanced load corresponding to the load under the maximum load (for example: the maximum load is 5kg, and the third anti-eccentricity value is the resistance when the load is 5kg).

[0109] Optionally, the washing machine control method provided in the embodiment of the present application also includes: obtaining a third position and a fourth position; determining a second spacing and a second eccentricity value corresponding to the second spacing based on the third position and the fourth position; obtaining a fifth position and a sixth position; determining a third spacing and a third eccentricity value corresponding to the third spacing based on the fifth position and the sixth position; determining a second anti-eccentricity value based on the second spacing and the second eccentricity value, and determining a third anti-eccentricity value based on the second spacing, the third spacing and the third eccentricity value.

[0110] In the present application embodiment, Figure 4 The schematic diagram of the process flow for determining the anti-eccentricity value is shown in the figure. In the test phase of the washing machine, the third position of the first position sensor and the fourth position of the second position sensor can be obtained. The third position is the first preset position of the inner drum (the position at which the inner drum has the maximum displacement during the test), and the fourth position is the second preset position of the outer drum (the position at which the outer drum has the maximum displacement during the test); the second spacing m is determined according to the third position and the fourth position. k and the maximum eccentricity value in the cylinder (the second eccentricity value) M k .

[0111] Further, when determining the second spacing m k and the maximum eccentricity value M in the cylinder k After that, according to m k and M k Calculate the second anti-eccentricity value G k , G kM k The distance m that the inner drum moves for the corresponding weight of the clothes k The corresponding anti-eccentricity value.

[0112] In the present application embodiment, Figure 4 As shown, during the washing machine testing phase, the fifth position of the first position sensor and the sixth position of the second position sensor can also be obtained, the fifth position being the second preset position of the inner drum of a certain model of washing machine (for example, model A) (the position of the maximum displacement of the inner drum when it is fully loaded during the test of model A), and the sixth position being the second preset position of the outer drum of a certain model of washing machine (for example, model A) (the position of the maximum displacement of the outer drum during the test of model A); the third spacing mi and the maximum eccentricity value (third eccentricity value) Mi in the drum are determined according to the fifth position and the sixth position.

[0113] It should be noted that M i It is the distance between the inner drum and the outer drum actually tested by the sensor. Because there are batch differences between machines, there will be deviations between the distance mk of the produced machine and the distance mk tested in the laboratory. mi corresponds to the limit value produced by a certain model. In theory, the mk of a washing machine of a certain model produced should be greater than mi. Therefore, the maximum eccentricity M in the drum i Less than M k .

[0114] Further, after determining the third spacing mi and the maximum eccentricity value Mi in the drum, the third anti-eccentricity value Gi can be calculated based on mi and Mi, where Gi is the anti-eccentricity value corresponding to the inner drum moving distance mi under the clothes of the corresponding weight of Mi, and Gi is stored in the microcontroller.

[0115] Specifically, the calculation formula of Gi is as follows:

[0116]

[0117] In the embodiment of the present application, after determining the second anti-eccentricity value and the third anti-eccentricity value, the dehydration coefficient is calculated according to the second anti-eccentricity value and the third anti-eccentricity value. The specific calculation formula is as follows:

[0118]

[0119] Where a is the dehydration coefficient.

[0120] It should be noted that a may be greater than 1 or less than 1, depending on the current state of the washing machine. If it is greater than 1, it means that the machine has enough space to properly reach a higher speed without hitting the drum or shifting.

[0121] S204: Determine the rotation speed of the washing machine according to the first anti-eccentricity value and the dehydration coefficient.

[0122] In the embodiment of the present application, the first anti-eccentricity value G can be obtained according to the calculated j And the dehydration coefficient a determines the speed of the washing machine during the dehydration operation stage.

[0123] Optionally, according to the first anti-eccentricity value G j The speed determined by the dehydration coefficient a can also be applied to other stages, such as the washing stage, etc.

[0124] Before determining the rotational speed of the washing machine according to the first anti-eccentricity value and the dehydration coefficient, optionally, the washing machine control method provided in the embodiment of the present application also includes: determining the mapping relationship between the anti-eccentricity value and the rotational speed of the washing machine according to the third anti-eccentricity value, and the mapping relationship is used to determine different rotational speeds corresponding to different anti-eccentricity values.

[0125] In the embodiment of the present application, the speed corresponding to different anti-eccentricity values ​​can be set for the washing machine according to the third anti-eccentricity value determined in the test phase. The specific mapping relationship is shown in Table 1:

[0126] Table 1

[0127] Anti-eccentricity value Speed Gi<200 Ni=1400rpm 200≤Gi<300 Ni=1200rpm 300≤Gi<400 Ni=1000rpm 400≤Gi<600 Ni=800rpm 600≤Gi<800 Ni=400rpm

[0128] Specifically, different rotation speeds Ni (for example: N1=400rpm, N2=600rpm, N3=800rpm, N4=1000rmp, N5=1200rpm, N6=1400rp) corresponding to different eccentricity values ​​Gi (i=1, 2, 3, ...N) can be set in advance according to the third anti-eccentricity value of the washing machine.

[0129] It should be noted that the unit of the anti-eccentricity value is gram (g). For example, the maximum anti-eccentricity capacity of a washing machine is 1000g, that is, the maximum Gi is 1000g.

[0130] It should also be noted that in the embodiment of the present application, when the anti-eccentricity value is greater than 800g, the washing machine can be controlled to stop running, that is, the speed is 0rpm. The values ​​in Table 1 are only examples and can be modified or adjusted according to actual conditions.

[0131] Optionally, the washing machine control method provided in the embodiment of the present application further includes: determining the rotation speed from a mapping relationship according to the first anti-eccentricity value and the dehydration coefficient.

[0132] In the present application embodiment, Figure 5The schematic diagram of the washing machine rotation speed determination process is shown. According to the corresponding relationship between the preset eccentricity value and the rotation speed, combined with the real-time anti-eccentricity value Gj and the dehydration coefficient a, the rotation speed can be determined. Before the washing machine runs for dehydration, the actual eccentricity value Gj of the current laundry is detected. If Gj < Gi * a, the rotation speed Nj is executed; if Gj > Gi * a, then it is judged whether Gj < Gi + 1. If it is determined that Gj < Gi + 1, the rotation speed Nj - 1 gear is executed; if Gj > Gi + 1, then it is judged whether Gj > Gi + 2. If it is determined that Gj > Gi + 2, the rotation speed Nj - 2 gear is executed until Nj - i < 400 rpm, and the operation stops.

[0133] For example, the maximum anti-eccentricity capacity designed for a certain washing machine prototype is 1000 g (Gk), and the distance between the inner tub and the outer tub corresponding to 1000 g is 7 mm (Mk); when mass-produced in the factory, it is actually detected that the maximum anti-eccentricity capacity of this model is 900 g (the maximum Gi), and the corresponding distance between the inner tub and the outer tub is 6 mm (Mi, Mi should be less than Mk, and in the extreme state, it is allowed to be equal to Mk). Then it can be considered that the maximum anti-eccentricity capacity that this model can operate is 900 g (the maximum Gi). Correspondingly, the given dehydration coefficient of this model can be a = 900 / 1000 = 0.9.

[0134] Optionally, different laundry states are different, so the eccentricity is different. Suppose the actual measured eccentricity value of the laundry in a certain washing program is 500 g; 500 * 0.9 = 450 g, and 400 g < 450 g < 600 g. Therefore, this machine will use a rotation speed of 800 rpm for dehydration.

[0135] It should be noted that the corresponding relationship between the eccentricity value and the rotation speed is a safe and reasonable value given based on laboratory tests. However, since the machine used in laboratory tests is a prototype and cannot fully adapt to all models, the dehydration coefficient is introduced.

[0136] Through the embodiments of the present application, the first position and the second position are determined. The first position is the position of the current inner tub, and the second position is the position of the current outer tub; the first anti-eccentricity value is determined according to the first position and the second position, and the first anti-eccentricity value is used to characterize the ability of the current washing machine to resist unbalanced loads during operation; the dehydration coefficient of the washing machine is determined, and the dehydration coefficient is used to adjust the rotation speed of the washing machine during the dehydration operation stage; according to the first anti-eccentricity value and the dehydration coefficient, the technical solution for determining the rotation speed of the washing machine can accurately judge the eccentricity situation of the washing machine according to the positions of the inner tub and the outer tub, and adjust the rotation speed of the washing machine during the dehydration operation stage according to the eccentricity situation, so as to achieve the technical effect of avoiding collision between the inner tub and the outer tub of the washing machine.
