[0038] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0040] Please refer to the following: Figure 1 and Figure 2This embodiment provides a filter cleaning control device, which includes a first slide rail assembly 21 and a second slide rail assembly 22. The first slide rail assembly 21 is disposed on the filter 10 along a first direction, and the second slide rail assembly 22 is disposed on the filter 10 along a second direction, the first and second directions intersecting. The filter cleaning control device also includes a cleaning detection module 30 and a drive control module 40. The cleaning detection module 30 is disposed on the second slide rail assembly 22, and the drive control module 40 is electrically connected to the cleaning detection module 30.

[0041] In specific implementation, the drive control module 40 is used to drive the second slide rail assembly 22 to move along the first slide rail assembly 21, and to drive the cleaning detection module 30 to move along the second slide rail assembly 22; the cleaning detection module 30 is used to detect the dirt and clogging of the filter screen 10 when it moves along the second slide rail assembly 22 and output a corresponding detection signal; the drive control module 40 is also used to control the second slide rail assembly 22 and the cleaning detection module 30 to stop moving when the detection signal meets the preset conditions, and to control the cleaning detection module 30 to clean the filter screen 10.

[0042] In this embodiment, the filter cleaning control device is controlled by the drive control module 40 to move the second slide rail assembly 22 along the first slide rail assembly 21, and simultaneously controls the cleaning detection module 30 to enter the detection state and output a corresponding detection signal while moving along the second slide rail assembly 22. If the detection signal meets the preset conditions, it indicates that the cleaning detection module 30 is currently clogged. Then, the drive control module 40 will control the second slide rail assembly 22 and the cleaning detection module 30 to stop moving, and clean the filter 10, thereby effectively alleviating the current problem of clogged air conditioning filter 10 and inconvenient cleaning, which is beneficial to optimizing the user experience.

[0043] After the cleaning detection module 30 has been cleaning for a period of time, if the detection signal output by the cleaning detection module 30 does not meet the preset conditions, it indicates that the dirt blockage at the location of the cleaning detection module 30 has been relieved. Then, the drive control module 40 controls the cleaning detection module 30 to work for a period of time and then controls the cleaning detection module 30 to stop working. At the same time, it controls the second slide rail assembly 22 to continue moving along the first slide rail assembly 21, and the cleaning detection module 30 to continue moving along the second slide rail assembly 22, continuing to detect the dirt blockage of the filter screen 10, repeating the above process to achieve automatic cleaning of the filter screen 10.

[0044] Please refer to the following: Figure 3 and Figure 4In some embodiments, the cleaning detection module 30 includes a detection unit 32 and a cleaning unit 31. The detection unit 32 and the cleaning unit 31 are connected and disposed together on the second slide rail assembly 22. Both the detection unit 32 and the cleaning unit 31 are electrically connected to the drive control module 40. The detection unit 32 is used to detect the dirt and clogging status of the filter 10 according to the control of the drive control module 40 when it moves along the second slide rail assembly 22, and outputs a corresponding detection signal to the drive control module 40. Specifically, the drive control module 40 is used to control the second slide rail assembly 22 and the cleaning unit 31 to stop moving when the detection signal meets a preset condition, so as to control the cleaning unit 31 to clean the filter 10. After the cleaning unit 31 has cleaned for a period of time, if the detection signal output by the detection unit 32 does not meet the preset condition, it indicates that the dirt and clogging at the location of the cleaning unit 31 has been relieved. Then the drive control module 40 controls the cleaning unit 31 to work for a period of time and then controls the cleaning unit 31 to stop working. Simultaneously, the second slide rail assembly 22 continues to move along the first slide rail assembly 21, and the cleaning unit 31 and the detection unit 32 continue to move along the second slide rail assembly 22 to continue detecting the dirt and clogging status of the filter screen 10. This process is repeated to achieve automatic cleaning of the filter screen 10. Specifically, while the cleaning unit 31 is cleaning, the detection unit 32 can operate continuously or intermittently; when the cleaning unit 31 stops working, the detection unit 32 enters a continuous detection state.

[0045] Please see Figure 5 In some embodiments, the detection unit 32 includes a light wave transmitter L1 and a light wave receiver L2. The input terminal of the light wave transmitter L1 is connected to the drive control module 40, and the output terminal of the light wave transmitter L1 is grounded. The light wave receiver L2 is connected to the drive control module 40. The light wave transmitter L1 is used to output a light wave signal according to the control of the drive control module 40, and the light wave receiver L2 is used to receive the light wave signal and output a corresponding detection voltage as a detection signal according to the intensity of the received light wave signal.

[0046] In this embodiment, the drive control module 40 controls the light wave transmitter L1 to output a light wave signal via the LED signal terminal, which is received by the light wave receiver L2. If the light wave signal received by the light wave receiver L2 is strong, it indicates that the light wave reception by the light wave receiver L2 is unobstructed, and the filter 10 is not clogged. The corresponding detection voltage output by the light wave transmitter L1 to the drive control module 40 via the REC signal terminal is greater than or equal to a preset value, indicating that the detection signal does not meet the preset condition. If the light wave signal received by the light wave receiver L2 is weak, it indicates that the light wave reception by the light wave receiver L2 is obstructed, and the filter 10 is severely clogged. The detection voltage output by the light wave transmitter L1 to the drive control module 40 via the REC signal terminal is less than the preset value, indicating that the detection signal meets the preset condition. Therefore, the drive control module 40 can determine the clog status by the magnitude of the detection voltage output by the light wave transmitter L1, thereby achieving real-time detection of the clog status of the filter 10 through the detection unit 32.

[0047] In some embodiments, the cleaning unit 31 includes a roller brush and a roller brush motor. The roller brush motor is electrically connected to the drive control module 40 and connected to the roller brush. The drive control module 40 is further configured to control the roller brush motor to work when the detected voltage is less than a preset voltage, so as to drive the roller brush to clean the filter screen 10, so as to achieve automatic cleaning of the filter screen 10.

[0048] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the cleaning detection module 30 further includes a sterilization unit 33, which is disposed on the second slide rail assembly 22 and connected to the cleaning unit 31. The sterilization unit 33 is also electrically connected to the drive control module 40. The drive control module 40 is also used to control the sterilization unit 33 to work when the detection voltage is less than a preset voltage. Essentially, while the drive control module 40 controls the cleaning unit 31 to perform cleaning, it also controls the sterilization unit 33 to participate in the work, sterilizing and disinfecting the filter 10, thereby improving the safety and reliability of the air conditioner and optimizing the user experience.

[0049] Please see Figure 8In one embodiment, the first slide rail assembly 21 includes a first slide rail 211 and a first motor 212, and the second slide rail assembly 22 includes a second slide rail 221 and a second motor 222; the drive control module 40 includes a first drive unit 41, a second drive unit 42, a third drive unit 43, a fourth drive unit 44, and a controller 45. The first drive unit 41, the second drive unit 42, the third drive unit 43, and the fourth drive unit 44 are all electrically connected to the controller 45; the first drive unit 41 is also electrically connected to the first motor 212, the second drive unit 42 is also electrically connected to the second motor 222, the third drive unit 43 is also electrically connected to the roller brush motor; and the fourth drive unit 44 is electrically connected to the sterilization unit 33.

[0050] The first drive unit 41 drives the first motor 212 to work, causing the second slide rail 221 to move along the first slide rail 211; the second drive unit 42 drives the second motor 222 to work, causing the detection unit 32, cleaning unit 31, and sterilization unit 33 to move together along the second slide rail 221; the third drive unit 43 drives the roller brush motor to work, thereby driving the roller brush to clean the filter screen 10; the fourth drive unit 44 drives the sterilization unit 33 to work; the controller 45 controls the working status of the first drive unit 41, the second drive unit 42, the third drive unit 43, and the fourth drive unit 44 respectively, thereby realizing effective control of the second slide rail 221, the cleaning unit 31, the detection unit 32, and the sterilization unit 33, ensuring that each unit can work independently while also working collaboratively according to the actual situation, which is conducive to realizing the automated cleaning function of the filter screen 10.

[0051] Please see Figure 9 In one embodiment, the first drive unit 41 includes a first drive chip IC1. The input terminal of the first drive chip IC1 is connected to the controller 45, and the output terminal of the first drive chip IC1 is connected to the first motor 212. The first drive chip IC1 is connected to a first port CN1, through which it is connected to the first motor 212. The first drive chip IC1 receives control signals from the controller 45 via its input terminals (such as IN4, IN5, IN6, and IN7) to control the operating state of the first motor 212, thereby controlling the operating state of the second slide rail 221.

[0052] Please see Figure 10In one embodiment, the second drive unit 42 includes a second drive chip IC2. The input terminal of the second drive chip IC2 is connected to the controller 45, and the output terminal of the second drive chip IC2 is connected to the second motor 222. The second drive chip IC2 is connected to a second port CN2, through which it is connected to the second motor 222. The second motor 222 drives the cleaning unit 31 and the detection unit 32 to move along the second slide rail 221. If a sterilization unit 33 is provided, in this embodiment, the sterilization unit 33 can be integrally disposed on the second slide rail 221 with the cleaning unit 31 and the detection unit 32, so as to ensure that the sterilization unit 33 can participate in sterilization and disinfection simultaneously when the cleaning unit 31 cleans the filter 10.

[0053] Please see Figure 11 In one embodiment, the third drive unit 43 includes a first switch Q1 and a first optocoupler OP1. The first terminal of the first switch Q1 is connected to the controller 45, the second terminal of the first switch Q1 is grounded, the third terminal of the first switch Q1 is connected to pin 1 of the first optocoupler OP1, pin 2 of the first optocoupler OP1 is energized, pin 3 of the first optocoupler OP1 is grounded, and pin 4 of the first optocoupler OP1 is connected to the cleaning unit 31. Pin 4 of the first optocoupler OP1 can be connected to the cleaning unit 31 via a third port CN3. The controller 45 outputs a PWM signal to control the switching of the first switch Q1, thereby outputting a corresponding control signal to the cleaning unit 31 via the first optocoupler OP1 to control the operating state of the cleaning unit 31.

[0054] In another embodiment, the third drive unit 43 further includes a second optocoupler OP2. Pin 1 of the second optocoupler OP2 is connected to the cleaning unit 31, pin 2 is energized, pin 3 is grounded, and pin 4 is connected to the controller 45. In this embodiment, the second optocoupler OP2 is connected to the feedback terminal of the controller 45, providing the controller 45 with a feedback signal such as FAN_FG. The controller 45 can monitor the working status of the cleaning unit 31 based on this feedback signal. For example, when the roller brush motor is working, it can drive the roller brush to clean the filter 10. The controller 45 monitors the status of the roller brush motor through the feedback signal of the second optocoupler OP2, so as to control the duty cycle of the PWM signal according to the feedback signal, adjust the speed of the roller brush motor, and achieve control of the roller brush cleaning speed.

[0055] In this embodiment, the third drive unit 43 achieves electrical isolation by setting a first optocoupler OP1 and a second optocoupler OP2, which improves the safety of the drive circuit. Simultaneously, resistors and capacitors are provided around the first optocoupler OP1 and the second optocoupler OP2. The use of resistors and capacitors improves the stability of the operation of the first optocoupler OP1 and the second optocoupler OP2 and the reliability of signal transmission, thereby optimizing the performance of the control device.

The first end of the second switch Q2 is connected to the controller 45, the second end of the second switch Q2 is grounded, and the third end of the second switch Q2 is connected to the sterilization unit 33. In this embodiment, the controller 45 is connected to the second switch Q2 via a HEALTH signal terminal, and the third end of the second switch Q2 is connected to the sterilization unit 33 via a fourth port CN4. In this embodiment, the controller 45 provides corresponding control signals to the sterilization unit 33 by controlling the conduction or deactivation of the second switch Q2, thereby achieving effective control of the sterilization unit 33. For example, when the second switch Q2 is on, pin 3 of the fourth port CN4 is at a low level; conversely, when the second switch Q2 is off, pin 1 of the second port CN4 is at a high level.

[0057] The sterilization unit 33 in this embodiment includes an ion generator and an ultraviolet lamp. When the ion generator is working, it discharges and ionizes the air to purify the air. When the ultraviolet lamp is turned on, sterilization and disinfection can be performed through the ultraviolet lamp.

[0058] To illustrate the working process of the filter cleaning control device in this application in detail, the following specific embodiments are provided to explain the working process of the filter cleaning control device:

[0059] When the filter cleaning control device is applied to an air conditioner, the controller 45 responds to the cleaning command from the remote control. After time t0, the controller 45 controls the first slide rail 211 and the second slide rail 221 to move the cleaning unit 31, the detection unit 32, and the sterilization unit 33 to various positions on the filter 10. At this time, the detection unit 32 is in working condition, detecting the dirt and clogging status of various positions on the filter 10 in real time. When the detection voltage output by the detection unit 32 is less than a preset value, it indicates that the degree of dirt and clogging of the filter 10, a1, is greater than the preset threshold a0. At this time, the controller 45 controls the first slide rail 211 to stop moving and simultaneously controls the second motor 222 to stop rotating. The roller brush motor rotates to control the roller brush to clean the filter 10, and at the same time, the sterilization unit 33 also enters working condition. The rotation speed of the roller brush motor can be determined by the deviation between the degree of dirt and clogging, a1, and the preset threshold, a0. When the detection unit 32 detects that the degree of dirt blockage a1 at the cleaning position of the current cleaning unit 31 is equal to a0, it controls the cleaning unit 31 and the sterilization unit 33 to stop working after a time t1. Meanwhile, the first motor 212 and the second motor 222 continue to work, continuing to detect the dirt blockage at various positions in the filter screen 10. If there is an area where the degree of dirt blockage a1 is greater than the preset threshold a0, the above cleaning process is repeated to clean the filter screen 10. After the cleaning unit 31 and the detection unit 32 have completed the detection and cleaning of the entire filter screen 10, the controller 45 can, after a period of time, control the second slide rail 221 again to move the cleaning unit 31, the detection unit 32, and the sterilization unit 33 at various positions in the filter screen 10, repeating the above cleaning process.
