[0001] This disclosure relates to the field of washing machine control technology, specifically to a spin-drying control method, a spin-drying control device, a washing machine, and a readable storage medium. Background Technology
[0002] As users increasingly use single types of clothing, they wash and spin-dry clothes separately more frequently, putting greater strain on the low-load spin-drying capacity of washing machines.
[0003] Currently, washing machines do not differentiate between large and small loads when spinning clothes, and all use the same spinning logic. This results in a large amount of eccentricity when the washing machine is spinning under a small load, which can easily damage the washing machine and lead to a low completion rate of spinning under a small load. Summary of the Invention
[0004] This disclosure provides a dehydration control method, a dehydration control device, a washing machine, and a readable storage medium, which can reduce the risk of washing machine damage and improve the dehydration completion rate under light loads.
[0005] In a first aspect, embodiments of this disclosure provide a dehydration control method, the method comprising:
[0006] Responding to the dehydration command, the first eccentricity is obtained;
[0007] If the first eccentricity is less than the first preset eccentricity threshold, then the first dehydration process is executed;
[0008] Obtain the second eccentricity after the first dehydration process is completed;
[0009] If the second eccentricity is less than the second preset eccentricity threshold, then the second dehydration process is executed;
[0010] The first preset eccentricity threshold and the second preset eccentricity threshold are set according to the load weight associated with the dehydration command, and the first preset eccentricity threshold is greater than the second preset eccentricity threshold.
[0011] The rotational speed of the inner cylinder in the first dehydration process is less than that in the second dehydration process.

[0017] The first preset eccentricity threshold and the second preset eccentricity threshold are set according to the load weight associated with the dehydration command, and the first preset eccentricity threshold is greater than the second preset eccentricity threshold.
[0018] The rotational speed of the inner cylinder in the first dehydration process is less than that in the second dehydration process.
[0019] Thirdly, embodiments of this disclosure also provide a washing machine, including a memory storing multiple instructions; a processor loads instructions from the memory to execute the steps of any of the spin-drying control methods provided in embodiments of this disclosure.
[0020] Fourthly, embodiments of this disclosure also provide a readable storage medium storing a plurality of instructions adapted for loading by a processor to execute the steps of any of the dehydration control methods provided in embodiments of this disclosure.
[0021] Fifthly, embodiments of this disclosure also provide a computer program product, including a computer program or instructions, which, when executed by a processor, implement the steps of any dehydration control method provided in embodiments of this disclosure.
[0022] The solution adopted in the application embodiment responds to the spin-drying command and obtains a first eccentricity; if the first eccentricity is less than a first preset eccentricity threshold, a first spin-drying process is executed; a second eccentricity is obtained after the first spin-drying process is completed; if the second eccentricity is less than a second preset eccentricity threshold, a second spin-drying process is executed.

[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Furthermore, in the description of the embodiments of this disclosure, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Therefore, features defined with "first" or "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this disclosure, "multiple" means two or more, unless otherwise explicitly specified.
[0031] This disclosure provides a dehydration control method, a dehydration control device, a washing machine, and a readable storage medium.
[0032] Specifically, this embodiment will be described from the perspective of a dehydration control device, which can be integrated into a washing machine, that is, the dehydration control method of this embodiment can be executed by the washing machine.
[0033] The dehydration control method provided in this disclosure can be applied to devices such as washing machines and dryers.
[0034] The following detailed description is provided in conjunction with the accompanying drawings. In this embodiment, a washing machine is used as the executing entity. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.
[0035] Please refer to Figure 1 The specific process of this dehydration control method includes the following steps:
[0036] Step 101: Respond to the dehydration command and obtain the first eccentricity.
[0037] Step 102: If the first eccentricity is less than the first preset eccentricity threshold, then execute the first dehydration process;
[0038] Step 103: Obtain the second eccentricity after the first dehydration process is completed;
[0039] Step 104: If the second eccentricity is less than the second preset eccentricity threshold, then execute the second dehydration process;
[0040] Specifically, a first preset eccentricity threshold and a second preset eccentricity threshold are set according to the load weight associated with the dehydration command, wherein the first preset eccentricity threshold is greater than the second preset eccentricity threshold; the difference between the first dehydration process and the second dehydration process is that the rotational speed of the inner cylinder in the first dehydration process is less than the rotational speed of the inner cylinder in the second dehydration process.
[0041] Specifically, in response to a spin-drying command, the washing machine controls the inner drum to rotate, thereby obtaining a first eccentricity. This first eccentricity is compared with a first preset eccentricity threshold. If the first eccentricity is less than the first preset eccentricity threshold, the washing machine executes a first spin-drying process. After completing the first spin-drying process, the washing machine controls the inner drum to rotate again, thereby obtaining a second eccentricity. This second eccentricity is compared with a second preset eccentricity threshold. If the second eccentricity is less than the second preset eccentricity threshold, the washing machine executes a second spin-drying process.
[0042] It should be noted that this spin-drying control method is applied to scenarios involving small loads. Small loads can be single garments, such as sweaters or coats, or several short-sleeved shirts and shorts. Because small loads are usually small in size, they tend to be concentrated in a certain area of the washing machine drum. This can cause the drum to have a large eccentricity when the washing machine is spinning small loads, making it prone to colliding with the machine body and potentially damaging the washing machine. Therefore, this spin-drying control method determines the eccentricity before performing pre-spinning and main spin-drying, avoiding large eccentricities during small load spin-drying that could lead to uneven motor force and drum collisions with the machine body, thus reducing the risk of washing machine damage. Furthermore, a smaller eccentricity during small load spin-drying maximizes the drum's rotational speed, improving the spin-drying completion rate for small loads.
[0043] Specifically, the following provides a detailed explanation of each step:
[0044] Step 101: Respond to the dehydration command and obtain the first eccentricity.
[0045] In this step, the washing machine responds to the spin-drying command and controls the inner drum to rotate according to the preset eccentricity detection speed. Eccentricity is detected during the inner drum's rotation to obtain the first eccentricity. For example, the washing machine can be a front-loading washing machine or a regular washing machine; these machines perform washing and spin-drying operations by rotating the inner drum. Optionally, after the washing machine completes the washing operation, it usually performs a spin-drying operation. The washing machine can respond to the spin-drying command according to its own program settings and control the inner drum to rotate, thereby obtaining the first eccentricity. Optionally, when the user needs to spin-dry the clothes separately, they can input a spin-drying command into the washing machine. The washing machine responds to the spin-drying command and controls the inner drum to rotate, thereby obtaining the first eccentricity.
[0046] Furthermore, before obtaining the first eccentricity, the following steps are included:
[0047] Step a: Obtain the load weight in the inner cylinder and compare the load weight with the preset small load weight range;
[0048] Step b: If the load weight is within the preset small load weight range, then perform the step: obtain the first eccentricity.
[0049] In steps a to b, after the washing machine responds to the spin-drying command, it first needs to determine whether the load in the inner drum is a light load. The washing machine uses a weight sensor to obtain the weight of the load in the inner drum and compares the load weight with a preset light load weight range. If the load weight is within the preset light load weight range, it determines that a light load spin-drying is needed and invokes the corresponding light load spin-drying logic. The first step of the light load spin-drying logic is to obtain the first eccentricity formed by the light load in the inner drum. For example, the washing machine is pre-defined as a light load for loads weighing less than 2 kg, a medium load for loads weighing more than 2 kg but less than 4 kg, and a heavy load for loads weighing more than 4 kg. The washing machine uses a weight sensor to obtain the weight of the load in the inner drum. When the load weight is less than 2 kg, it determines that the current load is a light load. It is immediately apparent that the washing machine has specific spin-drying logic for medium and heavy loads, which will not be described in detail here.
[0050] Furthermore, after responding to the dehydration command and obtaining the first eccentricity, the process includes the following steps:
[0051] Step c: If the first eccentricity is greater than or equal to the first preset eccentricity threshold, the inner cylinder is rotated by the drive motor to distribute the eccentricity until the new first eccentricity is less than the first preset eccentricity threshold.
[0052] In this step, after the washing machine obtains the first eccentricity generated by the small load in the inner drum, it compares the first eccentricity with the first preset eccentricity threshold. If the first eccentricity is greater than or equal to the first preset eccentricity threshold, the washing machine controls the inner drum to rotate and distribute the load through the drive motor until the obtained new first eccentricity is less than the first preset eccentricity threshold.
[0053] It should be noted that the first preset eccentricity threshold is pre-set in the washing machine. During the design process, the washing machine first determines the maximum weight within the range of load weight associated with the spin-drying command. The range of load weight associated with the spin-drying command is the preset minimum load weight range. The maximum weight load is placed in the inner drum, and the inner drum is controlled to rotate at a preset eccentricity detection speed to obtain the first preset eccentricity threshold. For example, the preset minimum load weight range is less than 2 kg. The washing machine can determine that 2 kg is the maximum weight within the preset minimum load weight range, and then place a 2 kg load in the inner drum and control the inner drum to rotate at the washing machine's maximum speed. If the inner drum does not collide with the washing machine cabinet, eccentricity detection is performed, and the measured eccentricity is used as the first preset eccentricity threshold. If the inner drum will collide with the washing machine cabinet, the rotation speed of the inner drum is reduced until the inner drum does not collide with the washing machine cabinet, eccentricity detection is performed, and the measured eccentricity is used as the first preset eccentricity threshold.
[0054] Specifically, the step of distributing the inner cylinder by controlling its rotation via a drive motor until the newly obtained first eccentricity is less than a first preset eccentricity threshold includes:
[0055] Step c1: Drive the motor to control the inner cylinder to rotate to the first preset speed;
[0056] Step c2: If the inner cylinder rotates at the first preset speed for a first preset time, then control the inner cylinder to rotate at a preset eccentricity detection speed.
[0057] Step c3: Obtain a new first eccentricity. If the new first eccentricity is greater than or equal to the first preset eccentricity threshold, then drive the motor to control the inner cylinder to rotate to the second preset speed.
[0058] Step c4 continues until the newly obtained first eccentricity is less than the first preset eccentricity threshold.
[0059] Wherein, the first preset rotational speed is less than the second preset rotational speed, which is less than the preset eccentricity detection rotational speed.
[0060] In steps c1 to c4, when the washing machine determines that the first eccentricity is greater than or equal to the first preset eccentricity threshold, the washing machine drive motor controls the inner drum to rotate to the first preset speed and continuously controls the inner drum to rotate at the first preset speed for the first preset time to distribute the small load in the inner drum, thereby reducing the eccentricity generated by the small load in the inner drum. When the inner drum has rotated at the first preset speed for the first preset time, the washing machine controls the inner drum to increase from the first preset speed to the preset eccentricity detection speed. The washing machine performs eccentricity detection at the preset eccentricity detection speed to obtain a new first eccentricity, and then compares the new first eccentricity with the first preset eccentricity threshold. If the new first eccentricity is greater than or equal to the first preset eccentricity threshold, the washing machine drive motor controls the inner drum to rotate to the second preset speed and continuously controls the inner drum to rotate at the second preset speed for the second preset time to distribute the small and medium loads in the inner drum, thereby reducing the eccentricity generated by the small loads in the inner drum. When the inner drum rotates at the second preset speed for the second preset time, the washing machine controls the inner drum to increase from the second preset speed to the preset eccentricity detection speed. The washing machine performs eccentricity detection at the preset eccentricity detection speed to obtain the new first eccentricity until the obtained new first eccentricity is less than the first preset eccentricity threshold, then the washing machine executes the first spin-drying process.
[0061] For example, such as Figure 2As shown, V1 is the first preset speed, V2 is the second preset speed, and V is the preset eccentricity detection speed. V1 is less than V2 and less than V. The washing machine drive motor controls the inner drum to rotate to V1 and continuously controls the inner drum to rotate at V1 for a first preset time. When the inner drum has rotated at V1 for the first preset time, the washing machine controls the inner drum to rise from V1 to V and rotate to obtain a new first eccentricity. If the new first eccentricity is greater than or equal to the first preset eccentricity threshold, the washing machine drive motor controls the inner drum to fall from V to V2 and continuously controls the inner drum to rotate at V2 for a second preset time. When the inner drum has rotated at V2 for the second preset time, the washing machine controls the inner drum to rise from V2 to V and rotate to obtain a new first eccentricity. If the new first eccentricity is greater than or equal to the first preset eccentricity threshold, the washing machine repeats the process as follows. Figure 2 The distribution curve shown continues until the new first eccentricity is less than the first preset eccentricity threshold. It can be understood that when the new first eccentricity obtained from V1 to V is less than the first preset eccentricity threshold, the washing machine directly executes the first spin-drying process; similarly, when the new first eccentricity obtained from V2 to V is less than the first preset eccentricity threshold, the washing machine also directly executes the first spin-drying process.
[0062] Step 102: If the first eccentricity is less than the first preset eccentricity threshold, then execute the first dehydration process;
[0063] In this step, after the washing machine responds to the spin-drying command and obtains the first eccentricity, or after controlling the inner drum to rotate and obtain a new first eccentricity by the drive motor, if it is determined that the first eccentricity is less than the first preset eccentricity threshold, then the first spin-drying process is executed.
[0064] Specifically, the first dehydration process includes:
[0065] Step 1021: Control the inner cylinder to rotate at the preset eccentricity detection speed, and control the rotation speed of the inner cylinder to increase from the preset eccentricity detection speed to a third preset speed, wherein the third preset speed is less than the preset resonance speed.
[0066] In this step, the washing machine first controls the inner drum to rotate at a preset eccentricity detection speed for a period of time. Then, it controls the inner drum's speed to increase from the preset eccentricity detection speed to a third preset speed. Upon reaching the third preset speed, it immediately decreases from the third preset speed back to the preset eccentricity detection speed. The washing machine repeats this cycle a preset number of times, increasing the inner drum's speed from the preset eccentricity detection speed to the third preset speed and immediately decreasing it back to the preset eccentricity detection speed, thus completing the first spin-drying process. It should be noted that the first spin-drying process is a pre-spin-drying process, which is used to remove a portion of the water from the load and quickly reduce the eccentricity generated by the load. The third preset speed is lower than the preset resonance speed, which is the inner drum's speed when the inner drum and the washing machine reach resonance.
[0067] For example, such as Figure 3 As shown, V is the preset eccentricity detection speed, and V3 is the third preset speed. The washing machine increases the inner drum speed from V to V3, then immediately decreases it back to V, and then increases it again to V3 to complete the first spin-drying process. That is, the inner drum speed only needs to reach V3 twice to complete the first spin-drying process. V3 is below the resonance speed of the vibration system, which allows for larger eccentric water spinning without causing the drum to collide and shift.
[0068] Step 103: Obtain the second eccentricity after the first dehydration process is completed;
[0069] In this step, after the first dehydration process is completed, the washing machine increases the rotation speed of the inner drum to the preset eccentricity detection speed, thereby obtaining the second eccentricity after the completion of the first dehydration process.
[0070] Further, after obtaining the second eccentricity after the first dehydration process is completed, the process includes:
[0071] Step d: If the second eccentricity is greater than or equal to the second preset eccentricity threshold, the inner cylinder is rotated by the drive motor to distribute the eccentricity until the new second eccentricity is less than the second preset eccentricity threshold.
[0072] In this step, after the washing machine obtains the second eccentricity after the first spin-drying cycle, it compares the second eccentricity with a second preset eccentricity threshold. If the second eccentricity is greater than or equal to the second preset eccentricity threshold, the inner drum is rotated by the drive motor to distribute the eccentricity until a new second eccentricity is obtained that is less than the second preset eccentricity threshold. It should be noted that the process of distributing the eccentricity by controlling the inner drum rotation with the drive motor in this step is similar to... Figure 2 The distribution process shown is the same, so it will not be repeated here.
[0073] Furthermore, the second preset eccentricity threshold is pre-set in the washing machine. During the design process, the maximum weight of the load associated with multiple spin-drying commands is first statistically analyzed, and then the average of the load weights after multiple spin-drying is obtained as the pre-spin-drying load weight. The pre-spin-drying load weight must be a weight within a preset small load weight range. The pre-spin-drying load weight is determined within the preset small load weight range. The load of the pre-spin-drying load weight is placed in the inner drum, and the inner drum is controlled to rotate at a preset eccentricity detection speed. If the inner drum does not collide with the washing machine cabinet, eccentricity detection is performed, and the measured eccentricity is used as the second preset eccentricity threshold. If the inner drum will collide with the washing machine cabinet, the rotation speed of the inner drum is reduced until the inner drum does not collide with the washing machine cabinet, and eccentricity detection is performed again, and the measured eccentricity is used as the second preset eccentricity threshold.
[0074] Step 104: If the second eccentricity is less than the second preset eccentricity threshold, then execute the second dehydration process.
[0075] In this step, after the washing machine obtains the second eccentricity, if it determines that the second eccentricity is less than the second preset eccentricity threshold, it executes the second dehydration process; wherein, the second dehydration process is the main dehydration process, which is mainly to remove as much water as possible from the load and improve the dehydration completion rate.
[0076] Specifically, the second dehydration process is performed, including:
[0077] Step 1041: Control the rotational speed of the inner cylinder to increase from the preset eccentricity detection speed to the fourth preset speed, and control the inner cylinder to rotate at the fourth preset speed for a second preset time, wherein the fourth preset speed is greater than the preset resonance speed.
[0078] In this step, if the washing machine determines that the second eccentricity is less than the second preset eccentricity threshold, it controls the inner drum's rotation speed to increase from the preset eccentricity detection speed to the fourth preset speed, and controls the inner drum to rotate at the fourth preset speed for a second preset time to complete the main spin-drying process. Optionally, after the washing machine controls the inner drum's rotation speed to increase from the preset eccentricity detection speed to the fourth preset speed, it continuously monitors changes in the load weight. When the load weight is found to remain unchanged for a period of time, it indicates that the water in the load has been spun dry, thus completing the main spin-drying process. It should be noted that the fourth preset speed is greater than the preset resonance speed.
[0079] In this embodiment, the washing machine responds to a spin-drying command and obtains a first eccentricity. If the first eccentricity is less than a first preset eccentricity threshold, a first spin-drying process is executed. Then, a second eccentricity is obtained after the first spin-drying process is completed. If the second eccentricity is less than a second preset eccentricity threshold, a second spin-drying process is executed. By first determining that the eccentricity meets the conditions before proceeding with the first and second spin-drying processes, a large eccentricity is avoided during low-load spin-drying, which could lead to uneven motor force and the inner drum impacting the casing, reducing the risk of washing machine damage. Furthermore, a smaller eccentricity during low-load spin-drying maximizes the rotational speed of the inner drum, improving the washing machine's spin-drying completion rate under low loads.
[0080] In specific implementation, refer to Figure 4 After the low-load spin cycle begins, the washing machine first checks the current load OOB (OOB represents the magnitude of the eccentricity; the data value represents the magnitude of the eccentricity and is directly proportional to it). If the OOB limit A is met during the full-load pre-spin stage, the pre-spin logic is executed to enter the pre-spin stage (the first spin cycle). The pre-spin stage is used to spin out a portion of the water, reducing the load eccentricity and allowing for a faster transition to the main spin stage to complete the spin cycle. If the OOB does not meet the limit A at this time, a distribution action is performed to re-determine the OOB. After the pre-spin is completed, the load OOB is checked again. If the limit B is met during the full-load main spin stage, the main spin logic is executed to enter the main spin stage (the second spin cycle); otherwise, a distribution action is performed to re-determine the OOB. Once the main spin cycle is completed, the entire spin cycle is finished. Note that limit A must be greater than limit B.
[0081] This embodiment also provides a dehydration control device, which can be integrated into devices such as washing machines and dryers. Figure 5 As shown, the dehydration control device may include:
[0082] The first acquisition unit 1001 is used to acquire the first eccentricity in response to the dehydration command;
[0083] The first execution unit 1002 is used to execute the first dehydration process if the first eccentricity is less than the first preset eccentricity threshold.
[0084] The second acquisition unit 1003 is used to acquire the second eccentricity after the first dehydration process is completed;
[0085] The second execution unit 1004 is used to execute the second dehydration process if the second eccentricity is less than the second preset eccentricity threshold.
[0086] The first preset eccentricity threshold and the second preset eccentricity threshold are set according to the load weight associated with the dehydration command, and the first preset eccentricity threshold is greater than the second preset eccentricity threshold.
[0087] The rotational speed of the inner cylinder in the first dehydration process is less than that in the second dehydration process.
[0088] In an optional example, the first execution unit is also used for:
[0089] If the first eccentricity is greater than or equal to the first preset eccentricity threshold, the inner cylinder is rotated and distributed by driving the motor until the new first eccentricity is less than the first preset eccentricity threshold.
[0090] In an optional example, the first execution unit is also used for:
[0091] The drive motor controls the inner cylinder to rotate to the first preset speed;
[0092] If the inner cylinder rotates at the first preset speed for a first preset time, then the inner cylinder is controlled to rotate at a preset eccentricity detection speed.
[0093] Obtain a new first eccentricity; if the new first eccentricity is greater than or equal to the first preset eccentricity threshold, then drive the motor to control the inner cylinder to rotate to the second preset speed.
[0094] Until the newly acquired first eccentricity is less than the first preset eccentricity threshold;
[0095] Wherein, the first preset rotational speed is less than the second preset rotational speed, which is less than the preset eccentricity detection rotational speed.
[0096] In an optional example, the first execution unit is also used for:
[0097] The inner cylinder is controlled to rotate at the preset eccentricity detection speed, and the rotation speed of the inner cylinder is controlled to increase from the preset eccentricity detection speed to a third preset speed, wherein the third preset speed is less than the preset resonance speed.
[0098] In an optional example, the second execution unit is also used for:
[0099] If the second eccentricity is greater than or equal to the second preset eccentricity threshold, the inner cylinder is rotated and distributed by driving the motor until the new second eccentricity is less than the second preset eccentricity threshold.
[0100] In an optional example, the second execution unit is also used for:
[0101] The rotational speed of the inner cylinder is increased from the preset eccentricity detection speed to the fourth preset speed, and the inner cylinder is controlled to rotate at the fourth preset speed for a second preset time, wherein the fourth preset speed is greater than the preset resonance speed.
[0102] In an optional example, the first acquisition unit is also used for:
[0103] Obtain the load weight in the inner cylinder and compare the load weight with the preset small load weight range;
[0104] If the load weight is within the preset minimum load weight range, then the following step is performed: obtain the first eccentricity.
[0105] In an optional example, the response unit is used for:
[0106] Determine the maximum weight within the preset small load weight range, place the load of the maximum weight in the inner cylinder and control the inner cylinder to rotate at a preset eccentricity detection speed to obtain the first preset eccentricity threshold.
[0107] Obtain the pre-dehydration load weight within the range of the load weight associated with the dehydration command, place the load of the pre-dehydration load weight in the inner cylinder and control the inner cylinder to rotate at a preset eccentricity detection speed to obtain the second preset eccentricity threshold.
[0108] The solution in this embodiment responds to a spin-drying command and obtains a first eccentricity. If the first eccentricity is less than a first preset eccentricity threshold, a first spin-drying process is executed. A second eccentricity is obtained after the first spin-drying process is completed. If the second eccentricity is less than a second preset eccentricity threshold, a second spin-drying process is executed. By first determining that the eccentricity meets the conditions before performing pre-spin-drying and main spin-drying, a large eccentricity is avoided during low-load spin-drying, which could lead to uneven motor force and the inner drum impacting the casing, reducing the risk of damage to the washing machine. Furthermore, a smaller eccentricity is generated during low-load spin-drying, which can maximize the rotational speed of the washing machine's inner drum and improve the spin-drying completion rate for low loads.
[0109] Accordingly, this disclosure also provides a washing machine, such as... Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of a washing machine provided in an embodiment of this disclosure.

The processor 1101 is electrically connected to the touch screen display 1103, the radio frequency circuit 1104, the audio circuit 1105, the input unit 1106, and the power supply 1107. Those skilled in the art will understand that... Figure 6 The washing machine structure shown does not constitute a limitation on electronic devices and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0141] The touch display screen 1103 can be used to display a graphical user interface (GUI) and receive operation commands generated by the user interacting with the GUI. The touch display screen 1103 may include a display panel and a touch panel. The display panel can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the electronic device. These graphical user interfaces can be composed of graphics, text, icons, video, and any combination thereof. Optionally, the display panel can be configured using a liquid crystal display (LCD), organic light-emitting diode (OLED), or other similar technologies. The touch panel can be used to collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel), generate corresponding operation commands, and execute the corresponding program according to the operation commands. Optionally, the touch panel may include a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 1101. It can also receive and execute commands from the processor 1101. The touch panel can cover the display panel. When the touch panel detects a touch operation on or near it, it transmits the information to the processor 1101 to determine the type of touch event. Subsequently, the processor 1101 provides corresponding visual output on the display panel based on the type of touch event. In this embodiment, the touch panel and the display panel can be integrated into the touch display screen 1103 to achieve input and output functions. However, in some embodiments, the touch panel and the touch display screen 1103 can be implemented as two independent components to achieve input and output functions. That is, the touch display screen 1103 can also be used as part of the input unit 1106 to achieve input functions.
[0142] The radio frequency circuit 1104 can be used to transmit and receive radio frequency signals to establish wireless communication with network devices or other electronic devices, and to transmit and receive signals with network devices or other electronic devices.
[0143] Audio circuit 1105 can be used to provide an audio interface between a user and an electronic device via a speaker and a microphone. Audio circuit 1105 can convert received audio data into electrical signals and transmit them to the speaker, where the speaker converts them into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 1105, converted back into audio data, and then processed by processor 1101 before being transmitted via radio frequency circuit 1104 to, for example, another electronic device, or output to memory 1102 for further processing. Audio circuit 1105 may also include an earphone jack to provide communication between peripheral headphones and electronic devices.
[0144] The input unit 1106 can be used to receive input numbers, characters, or user characteristic information (such as fingerprints, iris, facial information, etc.), and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control.
[0145] Power supply 1107 is used to supply power to various components of electronic device 1100. Optionally, power supply 1107 can be logically connected to processor 1101 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. Power supply 1107 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.
