For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B, and C.

[0045] As described in the background technology, the filters of air conditioners currently on the market do not have automatic detection functions such as dust, and usually require manual detection of the dust status of the filters. Users generally do not pay too much attention to their status, so the filters are not cleaned for a long time, resulting in pollution to the use environment when the air conditioner is working, dust blocking the air inlet of the air conditioner, and directly affecting the cooling effect of the air conditioner. Therefore, users can only discard the air conditioner they have purchased and buy a new air conditioner with automatic dust detection function to avoid the many problems caused by the air conditioner without automatic dust detection function. However, discarding the air conditioner without automatic dust detection function will cause problems such as waste of resources.

[0046] In order to solve the above problems, the present application provides a dust status detection scheme. In the scheme of the present application, a filter dust detection device that can be adaptively connected to the existing air conditioning structure is designed, and the device is used to automatically detect the dust on the filter of the air conditioner to obtain the dust status on the filter. The scheme of the present application can monitor the cleanliness of the filter in real time, which is convenient for users to clean or replace the dust on the filter in time, reducing the risk of dust blockage, maintaining the air inlet of the air conditioner unobstructed, ensuring the efficient operation of the air conditioning system, and providing users with a more comfortable and energy-saving experience; at the same time, it avoids energy waste, thereby extending the service life of the air conditioning system, that is, it can provide an automatic dust detection function for existing air conditioners that do not have an automatic dust detection function, so that users do not need to buy new air conditioners with an automatic dust detection function on the filter.

[0047] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] According to one embodiment of the present application, the present application provides a filter dust detection device, such as Figure 1 As shown, the device is connected to an air conditioner, and is used to detect dust on a filter net of the air conditioner to obtain the dust status on the filter net.

[0049] In addition, the inventors have found through research that the degree of dirtiness of the filter can be detected by using different types of sensors and intelligent technologies. These sensors can detect dust particles of different sizes, including dust particles of the same size level as allergens, such as pollen, etc. To this end, in combination with different types of sensors, this application provides the following embodiments to explain how the filter dust detection device detects the dust status of the filter.

[0050] 1. Photoelectric sensor

[0051] According to one embodiment of the present application, Figure 2As shown, the dust detection device of the present application includes: a photoelectric sensor, a first controller, and: the photoelectric sensor is used to emit light to the filter, and receive the light reflected by the filter, and transmit the light emitted to the filter and the light reflected by the filter to the first controller; the first controller is used to detect dust on the filter based on the light emitted by the filter and the light reflected by the filter to obtain the dust status on the filter.

[0052] From the above description, it can be seen that the above embodiment of the present application realizes the detection of the dust status on the filter net in the air conditioner through the photoelectric sensor, and can monitor the cleanliness of the filter net in real time, so as to facilitate the user to clean the dust on the filter net in time or replace the filter net, thereby reducing the detection cost, reducing the risk of dust blockage, maintaining the air inlet of the air conditioner unobstructed, and ensuring the efficient operation of the air conditioner; at the same time, it avoids energy waste, thereby extending the service life of the air conditioner and providing users with a more comfortable and energy-saving experience.

[0053] According to one embodiment of the present application, the photoelectric sensor includes: a light-emitting tube for emitting light to the filter and transmitting it to the first controller; a first driving circuit for controlling the operating state of the light-emitting tube so that it can emit light; a light detector for receiving the light emitted by the light-emitting tube and passing through the filter, and emitting the received light passing through the filter to the first amplifying circuit; the first amplifying circuit for amplifying the light received by the light detector and transmitting it to the first controller. The first controller is used to give an electrical signal for emitting light to the first driving circuit, so that the first driving circuit controls the light-emitting tube to emit light to the filter, and based on the light emitted to the filter and the light transmitted by the first amplifying circuit, performs dust detection on the filter to obtain the dust state on the filter.

[0054] As can be seen from the above description, the above embodiment of the present application ensures that the light-emitting tube can emit light in the optimal state through the first driving circuit, thereby ensuring that the light intensity irradiated on the filter is stable and consistent, and the first amplification circuit is responsible for amplifying the weak light received by the light detector so that the first controller can read and analyze these signals more accurately, thereby obtaining a more accurate dust state detection result. This design not only improves the sensitivity and accuracy of the detection, but also effectively reduces the impact of external interference factors on the detection results, making the entire dust detection process more efficient and reliable.

[0055] According to one embodiment of the present application, Figure 3 and Figure 4As shown, the dust detection device 110 of the present application includes: a first module 111, a second module 112 and a target controller, the first module 111, the first controller and the second module 112 are connected in sequence, the first module 111 is arranged on one side of the filter 140, the second module 112 is arranged on the other side of the filter 140, and the target controller outputs the dust state based on the difference between the first signal emitted by the first module 111 to the filter 140 and the second signal emitted by the first module 111 and passed through the filter 140 and received by the second module 112. In this embodiment, the first module 111 and the second module 112 are both fixedly connected to the filter 140.

[0056] Among them, the first module includes a light-emitting tube, which is a first light-emitting tube or a second light-emitting tube, the second module includes a light detector, which is an infrared light detector or a laser light detector, the first signal is infrared light or laser light, and the second signal is infrared light or laser light; the target controller is the first controller.

[0057] As can be seen from the above description, the above embodiment of the present application ensures that the first module can transmit signals in the optimal state through the driving circuit, thereby ensuring that the signal irradiated onto the filter is stable and consistent, and the second amplification circuit is responsible for amplifying the weak signal received by the second module so that the target controller can read and analyze these signals more accurately, thereby obtaining a more accurate dust state detection result. This design not only improves the sensitivity and accuracy of the detection, but also effectively reduces the impact of external interference factors on the detection results, making the entire dust detection process more efficient and reliable.

[0058] 2. Deep Learning Model

[0059] According to one embodiment of the present application, the dust detection device of the present application includes: a sensing and computing processing unit, which is used to process the filter to obtain a signal corresponding to the filter, and to obtain the dust status on the filter based on the signal corresponding to the filter using a deep learning model.

[0060] From the above description, it can be seen that combining the deep learning model to detect the dust status on the filter can improve the detection efficiency and improve the accuracy of the dust status detection results.

[0061] Among them, according to one embodiment of the present application, the sensing and computing processing unit of the present application includes: a silicon-based sensor, used to process the filter to obtain a signal corresponding to the filter; a processor, used to obtain the dust status on the filter based on the signal corresponding to the filter using a deep learning model.

[0062] From the above description, it can be seen that the above embodiments of the present application utilize silicon-based sensors combined with deep learning models to detect the dust status on the filter net. Among them, the silicon-based sensor has ultra-low power consumption characteristics, good cost advantages, and good decoupling from the processor, which can greatly reduce the difficulty of developing dust detection devices.

[0063] According to one embodiment of the present application, Figure 5 As shown, the sensing and computing processing unit of the present application also includes: a signal enhancement front end, which is used to enhance the signal corresponding to the filter obtained by the silicon-based sensor to improve the recognizability of the signal corresponding to the filter; an analog-to-digital converter, which is used to convert the signal corresponding to the filter after the enhancement processing, and transmit the converted signal corresponding to the filter to the processor for processing.

[0064] From the above description, it can be seen that the above embodiment of the present application processes the signal corresponding to the filter through the signal enhancement front end and the analog-to-digital converter, so that the processor can receive clearer, more accurate and more adaptable signals for processing to obtain a more accurate dust status of the filter.

[0065] 3. Image Sensor

[0066] According to one embodiment of the present application, Figure 6 As shown, the device includes: an image sensor for photographing the filter to obtain an image of the filter; and a second controller for detecting dust on the filter based on the image of the filter to obtain a dust state on the filter.

[0067] As can be seen from the above description, the dust detection device of the above embodiment of the present application uses an image sensor to shoot the filter, and controls the shooting process and analyzes the image of the filter through a second controller to detect the state of dust on it. This method provides a non-contact, intuitive and efficient dust detection method, which can accurately identify the distribution and density of dust on the filter.

[0068] According to one embodiment of the present application, Figure 7 As shown, the image sensor includes a first image sensor 121, which is connected to the second controller. The first image sensor 121 is arranged on one side of the filter 140. The second controller can transmit a shooting signal to the first image sensor 121. The first image sensor 121 is used to shoot the filter 140 to obtain a first image of the filter 140 and transmit it to the second controller. The second controller analyzes the image of the filter 140 based on an internal algorithm and then outputs the dust status.

[0069] According to one embodiment of the present application, Figure 8 , Fig. 9 , Fig.10 As shown, the first image sensor 121 in the dust detection device 110 of the filter 140 is fixed to the air conditioner body 130, and the position of the first image sensor 121 is different from that on one side of the filter 140 in the first embodiment.

[0070] Among them, according to one embodiment of the present application, the image sensor includes a second image sensor, the second image sensor is arranged on the other side of the filter 140, the second image sensor is connected to the second controller, the second controller can transmit a shooting signal to the second image sensor, the second image sensor is used to shoot the filter 140 to obtain a second image of the filter 140 and transmit it to the second controller, the second controller analyzes the first image and the second image based on an internal algorithm and then outputs the dust status.

[0071] It should be noted that the present invention does not limit the number of the first image sensor and the second image sensor, and they can be flexibly configured according to system requirements and accuracy.

[0072] It can be seen from the above description that by detecting the dust state on the filter screen through multiple image sensors, a more accurate dust detection result can be obtained.

[0073] 4. Differential pressure sensor

[0074] According to one embodiment of the present application, Fig.11 As shown, the device includes: a pressure difference sensor for detecting the wind force on both sides of the filter to obtain the wind force on both sides of the filter; a geometric pipe for fixing the position of the pressure difference sensor; a third controller for obtaining the pressure difference on both sides of the filter based on the pressure on both sides of the filter, and detecting the dust on the filter based on the pressure difference to obtain the dust state on the filter. According to another embodiment of the present application, the pressure difference sensor includes a plurality of pressure sensors, wherein: a part of the pressure sensors are installed on one side of the filter to obtain the pressure on the side of the filter based on the wind force on the side; another part of the pressure sensors are installed on the other side of the filter to obtain the pressure on the side of the filter based on the wind force on the side.

[0075] As can be seen from the above description, the above embodiment of the present application accurately measures the pressure on each side by installing multiple pressure sensors on both sides of the filter, and calculates the pressure difference on both sides of the filter based on these data. This method not only improves the accuracy and reliability of pressure detection, but also more accurately reflects the dust accumulation condition of the filter.

[0076] According to an embodiment of the present application, the dust detection device of the present application further includes: a plurality of geometric pipes for fixing the positions of a plurality of pressure sensors, wherein each geometric pipe is used to fix the position of any one of the pressure sensors.

[0077] For example, the dust detection device includes: a first pressure sensor, a second pressure sensor, a first geometric pipe and a second geometric pipe, the first geometric pipe is used to fix the first pressure sensor, the second geometric pipe is used to fix the second pressure sensor, and the open end of the first geometric pipe is opposite to the open end of the second geometric pipe.

[0078] As can be seen from the above description, the above embodiment of the present application accurately measures the pressure on each side by installing multiple pressure sensors on both sides of the filter to form a differential pressure sensor, and calculates the pressure difference on both sides of the filter based on these data. This method not only improves the accuracy and reliability of pressure detection, but also more accurately reflects the dust accumulation condition of the filter. At the same time, the dust detection device in the above embodiment of the present application uses multiple geometric pipes to fix the position of each pressure sensor, ensuring that each sensor can accurately measure the pressure at a specific position of the filter. This design not only improves the stability of the pressure sensor installation and the accuracy of positioning, reduces the measurement error caused by position offset, but also enhances the reliability of the dust detection device and the consistency of the data by optimizing the sensor layout.

[0079] Among them, according to one embodiment of the present application, the first controller, the second controller, and the third controller are all preset with corresponding dust status thresholds. The first controller, the second controller, and the third controller can all compare the dust status with the threshold. When the dust status exceeds the threshold, the first controller, the second controller, and the third controller all send out an alarm signal.

[0080] It can be seen from the above description that by setting a corresponding threshold value to give an early warning of the dust status on the filter, it is convenient for the user to clean the dust on the filter in time.

[0081] It should be noted that the above-mentioned embodiments of the present application utilizing photoelectric sensors, image sensors, pressure difference sensors and other sensors to detect the dust status on the filter net are only partial embodiments of the present application. With the development of sensors, corresponding dust detection devices can be designed using sensors with better performance and effects to detect dust on the filter net. No specific limitation is made here.

[0082] 5. Display unit

[0083] In addition, after the dust status on the filter in the air conditioner is detected by the filter dust detection device of the above embodiment, in order to allow the user to intuitively judge whether to clean the filter, the healthy use experience of the air conditioner is greatly improved.

According to another embodiment of the present application, the display unit is also configured to display the alarm signal obtained by the first controller, the second controller, the third controller, or the processor. According to another embodiment of the present application, the display unit is an LED screen, an OLED screen, or an LCD screen. After receiving the sensor signal, the controller processes it, and the processing information includes but is not limited to the sensitivity adjustment of dust and dust detection, the setting of the alarm threshold triggered by the dust and dust accumulation, and the processing of the accuracy of the detected object, etc. The processed information drives the LED through high and low levels, pulses, etc., or is displayed on carriers such as OLED and LCD screens to indicate the dust and dust accumulation status on the filter. After receiving the information, the user processes whether the filter is cleaned. After the filter is cleaned, the status indication signal disappears. It should be noted that the above-mentioned three display devices of LED screen, OLED screen, or LCD screen are only some embodiments of the present application. The specific selection of a display screen as the display unit can be based on the iterative update of the display screen, and a display screen with better performance can be selected as the display unit of the present application.

[0084] As can be seen from the above description, the above embodiment of the present application is equipped with a display unit in the filter dust detection device. This design allows the user to understand the dust accumulation of the filter at a glance, so as to accurately judge when to clean or replace it, which greatly improves the user's operating convenience and healthy use experience.

According to another embodiment of the present application, the wireless communication includes: Bluetooth or wifi. According to one embodiment of the present application, the remote control unit includes: a remote controller or a mobile phone.

[0086] From the above description, it can be seen that the information processed by the controller is transmitted to the remote control or mobile phone through wireless media (wireless communication methods such as Bluetooth and wifi) to indicate the dust and dust accumulation status on the filter. After receiving the information, the user will handle whether the filter is cleaned. After the filter is cleaned, the status indication signal disappears. This method allows users to remotely monitor the cleanliness of the filter. This design not only improves the convenience of user operation and reduces unnecessary manual inspection work, but also ensures that the user is notified in time when the filter needs to be cleaned, thereby effectively extending the service life of the equipment, improving air purification efficiency, and ensuring indoor air quality. After the filter is cleaned, the corresponding status indication signal disappears, providing users with an intuitive and efficient maintenance experience.

[0087] In addition, according to an embodiment of the present application, the present application provides a filter screen, on which the filter screen dust detection device of any of the above embodiments is integrated.

[0088] From the above description, it can be known that the filter of the above embodiment of the present application can be used to replace the existing filter without the filter dust detection function, so that the air conditioner has a specific filter dust detection function.

[0094] In addition, based on the above-mentioned filter dust detection device, the present application also proposes a filter, on which the filter dust detection device of any of the above-mentioned embodiments is integrated.
