Description

Technical Field

[0001] This application relates to the field of washing machine technology, specifically to a washing machine control method, device, electronic device, and computer-readable storage medium. Background Technology

[0002] The working principle of a washing machine is to use the movement of the inner drum to tumble and agitate the clothes, thereby separating stains and achieving the purpose of cleaning the clothes. Because the washing machine is constantly in motion, the clothes in the inner drum will shift to some extent relative to the axis of rotation. If the eccentricity is large and the machine is running at high speed for spin-drying, problems such as drum collision, displacement, and vibration may occur, affecting the user's washing process.

[0003] In existing technologies, the maximum eccentricity value of the washing machine can be preset, and when the eccentricity value of the washing machine reaches the maximum value, corresponding actions can be taken; alternatively, position sensors such as Hall sensors can be installed inside the washing machine to detect the movement path of the inner drum, so as to monitor the eccentricity in real time and take corresponding actions.

[0004] However, in practical applications, the pre-set maximum eccentricity value cannot be adapted to all washing machine models, and it cannot be identified when the anti-eccentricity capability of individual machines is abnormal, resulting in the drum collision phenomenon. In addition, the solution of avoiding the drum collision phenomenon by detecting the movement path of the inner drum in real time through position sensors requires high computing power and the calculation process is relatively complex.

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

[0067] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the aforementioned features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0068] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention 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.

[0069] First, let's explain the terms used in this application:

[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 tub: The outer tub surrounds the inner tub and is mainly used to hold water and detergent, and to ensure that water does not leak into other parts of the washing machine.

[0072] This application provides a washing machine control method, apparatus, electronic device, and computer-readable storage medium. Specifically, this application provides a washing machine control apparatus suitable for a washing machine control method. The washing machine control apparatus includes a washing machine and a main control device for the washing machine. The washing machine can be a pulsator washing machine, a drum washing machine, an agitator washing machine, a jet-type washing machine, or other washing equipment capable of washing clothes.

[0073] In existing technology, during the operation of a washing machine, the clothes inside the inner drum will undergo significant displacement due to the rotation of the inner drum and its axis of rotation.

[0074] For example, taking a front-loading washing machine as an example, in a front-loading washing machine, the drum rotates continuously, causing the clothes to tumble under the influence of gravity. This tumbling creates friction and agitation between the clothes, thus achieving the purpose of cleaning. However, during this continuous tumbling process, the clothes inside the drum will constantly shift, resulting in significant eccentricity (i.e., the center of gravity of the clothes in the inner drum deviates from the axis of rotation). Under these circumstances, if high-speed rotation is still used for washing or spin-drying, it may cause the inner and outer drums of the washing machine to collide, affecting the washing process and even leading to displacement, vibration, or damage to the washing machine.

[0075] Currently, to prevent problems such as drum collision, displacement, vibration, and damage in washing machines, the maximum eccentricity value of the washing machine can be set in advance, or the movement path of the inner drum can be detected in real time by a position sensor, thereby avoiding drum collision.

[0076] However, the pre-set maximum eccentricity value cannot be applied to all different washing machine models, and detecting the movement path of the inner drum through a position sensor requires high computing power.

[0077] Therefore, existing washing machine control methods have the technical problem of failing to effectively prevent the washing machine from colliding with the drum, shifting, vibrating, or being damaged due to the displacement of clothes.

[0078] This application provides a washing machine control method, apparatus, electronic device, and computer-readable storage medium. The method involves determining a first position and a second position, where 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 based on the first and second positions, the first anti-eccentricity value characterizing the washing machine's ability to resist unbalanced loads during operation; determining the washing machine's spin-drying coefficient, the spin-drying coefficient used to adjust the washing machine's rotation speed during the spin-drying phase; and determining the washing machine's rotation speed based on the first anti-eccentricity value and the spin-drying coefficient.

[0079] In summary, the washing machine control method in this application embodiment can accurately determine the eccentricity of the washing machine based on the positions of the inner and outer drums, and adjust the speed of the washing machine during the spin-drying stage according to the eccentricity, thereby achieving the technical effect of avoiding collision between the inner and outer drums of the washing machine.

[0080] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.

[0081] Please see Figure 1 , Figure 1This is a schematic diagram illustrating a scenario of the washing machine control method provided in this application embodiment. 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 can communicate with each other in any way, including but not limited to signal communication via electronic circuits or wireless signals. The wireless signals can be computer network communication using the TCP / IP protocol suite (TCP / IP) or User Datagram Protocol (UDP). The washing machine 100 can receive control signals from a remote control or control panel, and it can also receive instruction information sent by the main control device 200. The washing machine 100 can perform corresponding operations according to the corresponding instruction information.

[0082] In this embodiment, the washing machine 100 includes, but is not limited to, drum washing machines, pulsator washing machines, agitator washing machines, jet washing machines, and other washing equipment capable of washing clothes.

[0083] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of washing machines shown is more or less, for example Figure 1 Only one washing machine is shown in the image; the specific one is not specified here.

[0084] In addition, such as 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 microcontroller embedded inside the washing machine; no specific limitation is made here.

[0085] It should be noted that, Figure 1 The schematic diagram of the washing machine control system shown is merely an example. The washing machine control system and scenario described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of washing machine control systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

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

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

[0088] In this embodiment of the application, the first position is the current position of the inner cylinder, and the second position is the current position of the outer cylinder, such as... Figure 3 The schematic diagram of the washing machine shown illustrates that the washing machine includes a cabinet, an inner drum, and an outer drum. It also includes: a photosensitive device transmitter (first position sensor), a photosensitive device receiver (second position sensor), a microcontroller, and circuitry for communication between the microcontroller and the position sensors. The first position sensor is located on the inner drum, and the second position sensor is located on the outer drum. The first position of the inner drum can be acquired in real time or at a predetermined time using the first position sensor; similarly, the second position of the outer drum can be acquired in real time or at a predetermined time using the second position sensor.

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

[0090] In this embodiment, the first position sensor and the second position sensor can be various types of position sensors, such as optical sensors. As before... Figure 3 As shown, the emitting end of the photosensitive device can be placed at the inner end of the outer cylinder, and the receiving end of the photosensitive device can be placed at the outer end of the inner cylinder.

[0091] It should be noted that the embodiments of this application only use a photosensitive device as an example. The photosensitive device has a distance sensing function and can determine the distance between the receiver and the transmitter through the reflection of light. In addition to photosensitive devices, 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 this application.

[0092] Furthermore, in this embodiment of the application, multiple light sensors or other position sensors may be placed on a washing machine. The receiving end of the light sensor 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 and outer cylinders can be determined by light-sensing devices or other position sensors, thereby determining the distance between the inner and outer cylinders. This eliminates the need to acquire the movement trajectory of the inner or outer cylinders in real time, avoiding a large amount of complex calculations.

[0094] S202: Determine the first anti-eccentricity value based on the first position and the second position.

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

[0096] Optionally, the washing machine control method provided in this application embodiment further includes: determining a first distance and a first eccentricity value corresponding to the first distance based on the first position and the second position; and determining a first anti-eccentricity value based on the first distance and the first eccentricity value.

[0097] In this embodiment of the application, during the operation of the washing machine, the first distance between the inner drum and the outer drum can be determined based on the obtained first position of the inner drum and the second position of the outer drum. And further determine the first eccentricity value based on the first spacing. .

[0098] It's important to note that the eccentricity value is related to the weight of the clothes. Clothes of different weights, scattered or clustered in different positions within the drum, will cause the inner drum to deviate from its center, resulting in the eccentricity value. This eccentricity value can be calculated by altering the motor's rotational speed based on changes in current during operation. The eccentricity value is then determined by the speed variation within a cycle. Because of this eccentricity, the inner drum will tilt closer to the outer drum. The distance between the outer side of the inner cylinder and the inner side of the outer cylinder after tilting.

[0099] Optionally, the first gap 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 current spacing between the inner and outer cylinders, and the first eccentricity value is used to characterize the degree to which the center of gravity of the current inner cylinder deviates from the axis of rotation.

[0101] In this embodiment of the application, after determining the first spacing and the first eccentricity value, the first anti-eccentricity value can be further calculated based on the first spacing and the first eccentricity value. That is, the anti-eccentricity value can be calculated using 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 washing machine's ability 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 has shifted due to the operation of the washing machine, and the clothes after the center of gravity shift is the unbalanced load.

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

[0104] In this embodiment of the 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 rotation speed according to the dehydration coefficient during the spin-drying stage, thereby preventing the inner and outer drums from colliding and minimizing the vibration and displacement of the washing machine.

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

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

[0108] In this embodiment of the application, the second anti-eccentricity value is used to characterize the maximum ability of the washing machine to resist unbalanced load during operation. 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, if the maximum load is 5kg, the load corresponding to the second anti-eccentricity value is 6kg). The third anti-eccentricity value is used to characterize the washing machine's resistance to the maximum unbalanced load, that is, the washing machine's ability to resist the unbalanced load corresponding to the maximum load (for example, if the maximum load is 5kg, the third anti-eccentricity value is the resistance to the load of 5kg).

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

[0110] In the embodiments of this application, such as Figure 4 The flowchart illustrating the anti-eccentricity value determination process shows that during the washing machine testing phase, 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 when 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 when the outer drum has the maximum displacement during the test). The second gap is determined based on the third and fourth positions. The maximum eccentricity value inside the cylinder (the second eccentricity value) .

[0111] Furthermore, in determining the second spacing and the maximum eccentricity inside the cylinder After that, it can be based on and The second anti-eccentricity value was calculated. , for The distance the inner drum moves according to the weight of the garment The corresponding anti-eccentricity value.

[0112] In the embodiments of this application, it is still as follows 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 is the second preset position of the inner drum of a certain model of washing machine (e.g., model A) (the position of the maximum displacement of the inner drum when fully loaded during the testing of model A), and the sixth position is the second preset position of the outer drum of a certain model of washing machine (e.g., model A) (the position of the outer drum when the maximum displacement occurs during the testing of model A). The third gap is determined based on the fifth and sixth positions. The maximum eccentricity value inside the cylinder (the third eccentricity value) .

[0113] It should be noted that, This is the actual distance between the inner and outer cylinders as measured by sensors. Due to batch variations, the distance between the manufactured machine and the distance measured in the laboratory may differ slightly. There will be deviations. The theoretical maximum production capacity of a certain model of washing machine corresponds to the production limit of that model. Must be greater than Therefore, the maximum eccentricity inside the cylinder Less than .

[0114] Furthermore, in determining the third spacing and the maximum eccentricity inside the cylinder After that, it can be based on and The third anti-eccentricity value was calculated. , for The distance the inner drum moves according to the weight of the garment The corresponding anti-eccentricity value, and It is stored in the microcontroller.

[0115] Specifically, The calculation formula is as follows:

[0116]

[0117] In this embodiment of the application, after determining the second anti-eccentricity value and the third anti-eccentricity value, the dehydration coefficient is calculated based on 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 be set to a higher speed without hitting the drum or shifting.

[0121] S204: Determine the washing machine speed based on the first anti-eccentricity value and the dehydration coefficient.

[0122] In this embodiment, the first anti-eccentricity value can be calculated. The spin speed of the washing machine during the spin-drying stage is determined by the dehydration coefficient α.

[0123] Optionally, based on the first anti-eccentricity value The rotation speed determined by the dehydration coefficient α can also be applied to other stages, such as the washing stage.

[0124] Before determining the washing machine speed based on the first anti-eccentricity value and the dehydration coefficient, the washing machine control method provided in this application embodiment may optionally further include: determining the mapping relationship between the washing machine's anti-eccentricity value and the speed based on the third anti-eccentricity value, wherein the mapping relationship is used to determine different speeds corresponding to different anti-eccentricity values.

[0125] In this embodiment of the application, the washing machine can be set with different anti-eccentricity values ​​based on the third anti-eccentricity value determined during the testing phase. The specific mapping relationship is shown in Table 1.

[0126] Table 1

[0127]

[0128] Specifically, different eccentricity values ​​can be set in advance based on the washing machine's third anti-eccentricity value. (i=1,2,3,…N) different rotational speeds (For example: N1=400rpm, N2=600rpm, N3=800rpm, N4=1000rpm, N5=1200rpm, N6=1400rpm).

[0129] It should be noted that the unit of anti-eccentricity value is grams (g). For example, if a washing machine's maximum anti-eccentricity capability is 1000g, then the maximum value is... It is 1000g.

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

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

[0132] In the embodiments of this application, such as Figure 5 The schematic diagram shown illustrates the washing machine speed determination process. It can determine the speed based on a pre-set relationship between eccentricity and rotation speed, combined with real-time anti-eccentricity values. The spin speed is determined by the dehydration coefficient 'a'. Before the washing machine starts the spin cycle, the actual eccentricity value of the current load is detected. ,like < ×a, then the rotational speed is executed. ;like > ×a, then determine < +1, if confirmed < +1, then execute speed -1 gear; if > +1, then determine > +2, if confirmed > +2, then the rotation speed will be adjusted. -2 gears, until -i<400rpm, stop running.

[0133] For example, the maximum anti-eccentricity capability of a certain washing machine prototype is 1000g ( ), the distance between the inner and outer cylinders corresponding to 1000g is 7mm. Mass production began, and actual testing revealed that the maximum anti-eccentricity capability of this model is 900g (maximum). The corresponding distance between the inner and outer cylinders is 6mm. , smaller than In the limiting state, it is permissible to be equal to Therefore, it can be assumed that the maximum anti-eccentricity capability of this model is 900g (maximum). Accordingly, the dehydration coefficient given for this model can be a=900 / 1000=0.9.

[0134] Alternatively, different garments have different conditions, so the amount of eccentricity will be different. Suppose that the actual eccentricity value of the garments tested in a certain washing program is 500g; 500×0.9=450g, and 400g<450g<600g, so the machine will use a speed of 800rpm for spin drying.

[0135] It should be noted that the relationship between eccentricity and rotation speed is based on the safe and reasonable values ​​that have been tested in the laboratory. However, since the machine used in the laboratory test is a prototype, it cannot be fully adapted to all models, so a dehydration coefficient is introduced.

[0136] This application's embodiments employ a technical solution that involves determining a first position and a second position, where 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 based on the first and second positions, the first anti-eccentricity value being used to characterize the washing machine's ability to resist unbalanced loads during current operation; determining the washing machine's dehydration coefficient, the dehydration coefficient being used to adjust the washing machine's speed during the dehydration phase; and determining the washing machine's speed based on the first anti-eccentricity value and the dehydration coefficient. This technical solution can accurately determine the washing machine's eccentricity based on the positions of the inner and outer drums, and adjust the washing machine's speed during the dehydration phase accordingly, thereby achieving the technical effect of avoiding collisions between the inner and outer drums.
