[0056] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0057] Secondly, it should be noted that in the description of the embodiments of this application, the terms "inner" and "outer" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0058] Furthermore, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] Before introducing the embodiments of this application, the application background of the embodiments of this application will be explained first:

[0061] In real life, with the improvement of people's material living standards, washing machines have become an essential household appliance. Although washing machines can free people's hands and reduce the amount of labor, they cannot effectively clean locally soiled areas such as collars or cuffs. In order to clean clothes better, most users usually soak their clothes in the washing machine before washing them, and then manually scrub areas such as collars and cuffs before putting them into the washing machine.

[0062] However, since the water intake is determined by the washing machine's fuzzy control water intake function based on the weight of the clothes to be washed in the inner drum, if the clothes to be washed have been soaked by the user before being put into the washing machine, the determined water intake will be greater than the amount of water needed by the clothes because the clothes have absorbed a lot of water. Excessive water intake will dilute the cleaning solution, which may result in a lower accuracy of the determined water intake and the problem that the clothes to be washed cannot be cleaned properly due to the cleaning solution being too diluted.

[0063] To address the aforementioned problems, the inventive concept of this application is as follows: In the prior art, when clothes to be washed have absorbed a large amount of water, the weight of the clothes is greater than their actual weight. Directly determining the required water intake based on the current weight of the clothes leads to an overestimation of the water intake and low accuracy. Therefore, the inventors discovered that by controlling the inner drum of the washing machine to rotate according to a preset rotation rule after activating the fuzzy control water intake function, and performing spin-drying when a large amount of water has been absorbed, the water intake can be accurately determined based on the amount of water absorbed after spin-drying, thus avoiding the problem of clothes not being properly cleaned due to excessive water intake.

[0064] For example, the washing machine control method provided in this application embodiment can be applied to... Figure 1 The diagram shows one application scenario. Figure 1 This is a schematic diagram illustrating an application scenario of the washing machine control method provided in this application, used to solve the aforementioned technical problems. For example... Figure 1 As shown, this application scenario can include: washing machines and terminal devices (such as...) Figure 1 (The phone in the middle).

[0065] The terminal device can be equipped with an application that controls the washing machine to clean clothes. The terminal device can be a mobile phone, computer, remote control, etc.

[0066] In this embodiment, the application includes a fuzzy logic control for water inlet function. Users can click on this control, and the terminal device responds by generating a fuzzy logic control command to activate the water inlet function and sending it to the washing machine. Similarly, the remote control includes a fuzzy logic control button. Users can press this button, and the remote control responds by generating a fuzzy logic control command to activate the water inlet function and sending it to the washing machine.

[0067] Optionally, the washing machine's touch screen display can be equipped with a fuzzy control water inlet function control or a fuzzy control water inlet function button. The washing machine can respond to the user's operation of the fuzzy control water inlet function control or the fuzzy control water inlet function button to generate a fuzzy control water inlet function activation command.

[0068] Furthermore, the washing machine can receive a fuzzy control water inlet function activation command sent by the user through a terminal device or remote control, and activate the fuzzy control water inlet function. The washing machine can also activate the fuzzy control water inlet function based on its own generated fuzzy control water inlet function activation command.

[0069] After the washing machine activates the fuzzy control water inlet function, it controls the inner drum of the washing machine to rotate so that the clothes to be washed can drain water as the inner drum rotates. Based on the drainage situation, it is determined whether the clothes to be washed need to be spun dry.

[0070] The technical solution of this application will now be described in detail through specific embodiments.

[0071] It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0072] Figure 2 This is a flowchart illustrating an embodiment of the washing machine control method provided in this application. Figure 2 As shown, a photoelectric sensor is installed at the front end of the drain valve of the washing machine. The photoelectric sensor includes a transmitter and a receiver. The control method of the washing machine may include the following steps:

[0073] S21. After the washing machine turns on the fuzzy control water inlet function, control the transmitter of the photoelectric sensor to emit a light signal.

[0074] The washing machine can activate the fuzzy control water inlet function based on the fuzzy control water inlet function activation command sent by the user through the terminal device. It can also generate a fuzzy control water inlet function activation command in response to the user's click operation on the washing machine's touch screen display, and activate the fuzzy control water inlet function based on the fuzzy control water inlet function activation command.

[0075] Among them, the fuzzy control water inlet function is used to determine the amount of water to be inlet based on the weight of the clothes to be washed in the inner drum of the washing machine.

[0076] In one possible implementation, the washing machine pre-stores a mapping relationship between weight and water intake. After the washing machine obtains the weight of the clothes to be washed based on the rotation of the inner drum or the weighing module, the fuzzy control water intake function can obtain the water intake corresponding to the weight based on the mapping relationship.

[0077] For example, the mapping relationship between weight and water intake can be shown in Table 1.

[0078] Table 1

[0079] weight Water inflow Weight 1 Inlet water volume 1 Weight 2 Water inflow 2 Weight 3 Water inflow 3

[0080] Taking the mapping relationship shown in Table 1 as an example, if the weight of the clothes to be washed is weight 2, then the water intake determined according to the mapping relationship is water intake 2.

[0081] Alternatively, the mapping relationship between weight and water intake can also be achieved using the formula: y = ax, where y is the water intake, x is the weight, and a is a positive number.

[0082] It should be understood that the mapping relationship between weight and water intake can also be expressed by other formulas, which can be set according to the actual situation. This application embodiment does not impose specific limitations on this.

[0083] S22. Control the inner tub of the washing machine to rotate according to the preset rotation rules.

[0084] The preset rotation rules include preset rotation speed, preset rotation duration, and preset rotation direction.

[0085] For example, the preset rotation speed can be 10 revolutions per second, 11 revolutions per second, 12 revolutions per second, etc.; the preset rotation duration can be 5 seconds, 6 seconds, 7 seconds, etc.; and the preset rotation direction can be forward rotation or reverse rotation.

[0086] For example, the preset rotation rule can be to rotate forward for 5 seconds at a rotation speed of 10 revolutions per second, or to rotate forward for 5 seconds at a rotation speed of 10 revolutions per second, and then rotate backward for 5 seconds at a rotation speed of 10 revolutions per second.

[0087] It should be understood that the preset rotation rules may also include other content, which can be specifically limited according to the actual situation. The embodiments of this application do not impose specific limitations on this.

[0088] The preset rotation rules can be obtained from a configuration file sent by the server, or from a configuration file input by the user, or from other existing methods. This application embodiment does not impose specific limitations on these methods.

[0089] S23. When the receiver cannot receive the light signal transmitted by the transmitter, turn off the fuzzy control water inlet function and spin-dry the clothes to be washed.

[0090] In this embodiment of the application, a pulsator washing machine is used as an example for explanation. The photoelectric sensor is located at the bottom of the outer tub of the pulsator washing machine and at the front end of the drain valve. This is the lowest point of the entire cavity of the pulsator washing machine, and water will flow to this point as long as there is water in the tub.

[0091] It should be understood that when the receiving end cannot receive the light signal emitted by the transmitting end, it means that some water flows out when the clothes to be washed are rotating in the inner drum and enters the lowest part of the inner drum. Due to the refraction of light by the water, the receiving end cannot receive the light signal emitted by the transmitting end.

[0092] Optionally, the operating parameters of the dehydration process can be preset, including dehydration time, dehydration rotation direction, dehydration rotation speed, etc.

[0093] The dehydration of clothes can be achieved through the spin-drying function of a washing machine, the tumble-drying function, or a combination of both. It should be understood that other existing methods can also be used to remove the moisture absorbed by the clothes, thus achieving the desired dehydration.

[0094] The washing machine control method provided in this application embodiment, after the washing machine activates the fuzzy control water inlet function, controls the inner drum of the washing machine to rotate according to a preset rotation rule by controlling the transmitter of the photoelectric sensor to emit light signals. When the receiver cannot receive the light signals emitted by the transmitter, the fuzzy control water inlet function is turned off, and the clothes to be washed are spun dry. When the photoelectric sensor confirms that the clothes to be washed contain a large amount of water, the clothes are spun dry, which allows the fuzzy control water inlet function to more accurately obtain the amount of water entering during the washing process, saving water resources and avoiding the problem of not being able to clean the clothes properly due to excessive water dilution of the cleaning solution.

[0095] Optionally, in some embodiments, after the receiving end fails to receive the light signal emitted by the transmitting end, the transmitting end of the photoelectric sensor can be controlled to stop emitting light signals.

[0096] Optionally, in some embodiments, after S22, the fuzzy control water inlet function can be restarted so that the water inlet volume during the washing process can be accurately obtained based on the weight of the clothes to be washed after dehydration.

[0097] Optionally, in some embodiments, after S22, a prompt message may be output to remind the user that the clothes to be washed have been spun dry.

[0098] For example, the output of the prompt message may include the following methods:

[0099] 1) It can play preset music.

[0100] 2) Play the prompt message aloud.

[0101] 3) Send the prompt message to the smart speaker so that the smart speaker can play it aloud.

[0102] 4) Send a notification message to a terminal device pre-connected to the washing machine. For example, you can send an SMS message to the terminal device or a push notification to the terminal device's application.

[0103] 5) The prompts can be displayed on its own touch screen.

[0104] It should be understood that the washing machine can also output prompt information in other ways, which can be set according to the actual situation. This application embodiment does not impose specific limitations on this.

[0105] In this embodiment, the fuzzy control water inlet function can also be restarted by receiving a fuzzy control water inlet function activation command sent by the user through the terminal device, or by receiving a fuzzy control water inlet function activation command generated in response to the user's click operation on the touch screen of the washing machine.

[0106] Optionally, in some embodiments, after S22, the control method of the washing machine further includes the following steps: starting a timer to start timing, and monitoring whether the receiving end can receive the optical signal when the cumulative duration obtained by timing does not exceed a preset duration.

[0107] Accordingly, step S23 can be achieved through the following steps:

[0108] When the cumulative duration does not exceed the preset duration and the receiver cannot receive the light signal, the fuzzy control water inlet function is turned off, and the clothes to be washed are dehydrated.

[0109] Optionally, in some embodiments, after S23, the control method of the washing machine further includes the following steps: when the cumulative time does not exceed a preset time and the receiver can continuously receive the light signal, the water intake volume is determined according to the weight of the clothes to be washed, and the fuzzy control water intake function is turned off. That is to say, at this time the clothes to be washed are relatively dry and have absorbed less moisture, so the water intake volume determined according to the current weight of the clothes to be washed is more accurate.

[0110] In the above embodiment, since the clothes to be washed that have absorbed a lot of water will release a lot of water in the early stage of the inner drum rotation, if the cumulative time obtained by timing does not exceed the preset time, it can monitor whether the receiving end can receive the light signal. This can avoid the washing machine from continuously detecting the receiving end at unnecessary times (such as in the later stage of the inner drum rotation, when the clothes to be washed lose less water), thus saving the washing machine's computing resources.

[0111] Figure 3 This is a flowchart illustrating a second embodiment of the washing machine control method provided in this application. Figure 3 As shown, the control method of this washing machine may include the following steps:

[0112] S31. After the washing machine turns on the fuzzy control water inlet function, control the inner drum of the washing machine to rotate according to the preset rotation rules to obtain the target drainage volume of the washing machine.

[0113] The preset rotation rules include preset rotation speed, preset rotation duration, and preset rotation direction. The fuzzy control water inlet function is used to determine the water inlet volume based on the weight of the clothes to be washed in the inner tub.

[0114] In one feasible approach, a timer is started when the inner tub rotates according to a preset rotation rule. When the accumulated time exceeds the preset time, the cumulative drainage volume of the washing machine within that time is determined as the target drainage volume.

[0115] S32. When the target drainage volume exceeds the preset drainage volume, turn off the fuzzy control water inlet function and perform spin-drying treatment on the clothes to be washed.

[0116] The preset drainage volume can be obtained through a configuration file sent by the server, a configuration file input by the user, or a setting command sent by the user through the terminal device, which carries the preset drainage volume. It can also be obtained by responding to the user's click operation on the touch screen. This application embodiment does not impose specific limitations on this.

[0117] The washing machine control method provided in this application embodiment, after the washing machine activates the fuzzy control water inlet function, controls the inner drum of the washing machine to rotate according to a preset rotation rule to obtain the target drainage volume of the washing machine. When the target drainage volume exceeds the preset drainage volume, the fuzzy control water inlet function is turned off, and the clothes to be washed are spun dry. By using the target drainage volume and the preset drainage volume to confirm that the clothes to be washed contain a large amount of water, the clothes are spun dry, which allows the fuzzy control water inlet function to more accurately obtain the water volume during the washing process, saving water resources and avoiding the problem of not being able to clean the clothes properly due to excessive water dilution of the cleaning solution.

[0118] Optionally, in some embodiments, after S32, the fuzzy control water inlet function can be restarted so that the water inlet volume during the washing process can be accurately obtained based on the weight of the clothes to be washed after dehydration.

[0119] Optionally, in some embodiments, after S32, a prompt message may also be output to remind the user that the clothes to be washed have been spun dry.

[0120] Furthermore, it can also obtain the user's command to enable the fuzzy control water inlet function and re-enable the fuzzy control water inlet function.

[0121] Optionally, in some embodiments, after S32, the control method of the washing machine further includes the following steps: when the target drainage volume is less than or equal to the preset drainage volume, the water intake volume is determined according to the weight of the clothes to be washed, and the fuzzy control water intake function is turned off.
