[0002] With the development of the times and the improvement of living standards, air conditioners have entered thousands of households. The air conditioner filter is the first line of defense for fresh air to enter the room. It can filter out pollutants such as dust, bacteria, and hair in the fresh air to a certain extent, thereby purifying the fresh air. However, as the filter is used for a longer time, the pores of the filter will be blocked by the breeding of bacteria and dust, resulting in a decrease in the amount of air intake, and even causing the air outlet of the air conditioner to carry a large number of bacteria that are harmful to the human body. Therefore, the air conditioner filter needs to be cleaned regularly.

[0003] In the prior art, it is difficult to determine the dust accumulation of the air-conditioning filter in the home, and the filter cannot be cleaned in time. Most of them are cleaned once a month or quarterly. It is difficult for people to control when to clean the air-conditioning filter, and most households clean the air-conditioning filter manually. This method is not only time-consuming and labor-intensive, but improper cleaning may also cause damage to the air-conditioning filter and affect the filtering effect.

[0037] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0038] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0039] Figure 1 is a flow chart of the air conditioner filter dust removal method provided by the embodiment of the present invention, please refer to Figure 1 , this embodiment may include the following steps:

[0040] S101. Detecting the real-time weight of the air conditioning filter by means of a load sensor arranged at the air conditioning filter.

[0041] Specifically, when the air is turned on, the load sensor set at the air conditioner filter can be turned on at the same time, and the real-time weight of the air conditioner filter can be detected by the load sensor. It should be noted that the present application can realize automatic detection and automatic dust removal of the air conditioner filter. In this process, the controller can be the controller of the existing air conditioner itself (such as including the panel and corresponding modules or circuits mentioned later), or it can be a controller separately set for detection and dust removal.

[0042] S102: Determine the difference between the real-time weight and the preset weight threshold.

[0043] S103: When the real-time weight is greater than a preset weight threshold, an alarm is sounded, and dust is removed by an electrostatic precipitator arranged at the air conditioner evaporator.

[0044] Specifically, when the real-time weight is detected to be greater than the preset weight threshold, it means that the air conditioner filter needs to be dusted. In some embodiments of the present application, when the real-time weight is detected to be greater than the preset weight threshold, an alarm may be issued first, and the user may be notified. When the user confirms to perform dust removal, dust removal may be performed by an electrostatic precipitator provided at the air conditioner evaporator. Of course, in other embodiments of the present application, dust removal may also be performed directly when the real-time weight is detected to be greater than the preset weight threshold.

[0045] The present application provides a method for removing dust from an air conditioner filter, which detects the real-time weight of the air conditioner filter by a load sensor arranged at the air conditioner filter; determines the difference between the real-time weight and a preset weight threshold; when the real-time weight is greater than the preset weight threshold, an alarm is sounded, and dust is removed by an electrostatic precipitator arranged at the air conditioner evaporator. In this way, the real-time weight of the air conditioner filter is detected by the load sensor, so as to determine whether the air conditioner filter needs to be dusted, and when dusting is needed, dusting is automatically achieved by the electrostatic precipitator, which solves the problem that the air conditioner filter cannot be dusted in a timely and efficient manner in the prior art.

[0046] It can be understood that the same or similar parts of the above embodiments can be referenced to each other, and the contents not described in detail in some embodiments can refer to the same or similar contents in other embodiments.

[0047] It should be noted that, in the description of the present invention, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" refers to at least two.

[0048] Figure 2 is a schematic diagram of the structure of the air conditioner filter dust removal system provided by an embodiment of the present invention. The air conditioner filter dust removal method provided by the present application can be implemented by the system, such as Figure 2 As shown, the system may include an electrostatic precipitator and a buzzer 8, wherein the electrostatic precipitator specifically includes a high-voltage electrostatic power source 7 and a corona electrode 6. In addition, in the present application, the air conditioning filter dust removal system also includes a controller. In actual applications, the controller can be implemented by an air conditioning controller or control module installed therewith, or it can be a separately set controller. The present application takes the air conditioning controller or control module as an example for illustration.

[0049] like Figure 2As shown, in the prior art, since there is a certain space between the panel 3, the panel body 4 and the filter 2, the air conditioner has airflow in and out and the general human body will not touch it. Therefore, the present application can place the corona electrode 6 of the electrostatic precipitator therein (i.e., the target area between the panel 3, the panel body 4 and the filter 2), connect the positive electrode of the high-voltage static power source 7 to the evaporator 5 as a dust collecting electrode, connect the negative electrode of the high-voltage static power source 7 to the corona electrode 6, install the buzzer 8 behind the panel 3, and set the load sensor 9 under the filter 2 to measure the weight information of the filter.

[0050] On this basis, in some embodiments of the present application, the real-time weight of the air-conditioning filter is detected by a load sensor arranged at the air-conditioning filter, which may specifically include: after the air-conditioner is turned on, the real-time weight of the air-conditioning filter is cyclically detected based on the detection cycle and the detection cycle interval; wherein, for each detection cycle, the real-time weight of the air-conditioning filter is detected at a preset frequency by a load sensor arranged at the air-conditioning filter; and the highest and lowest values ​​of the real-time weight collected within the detection cycle are deleted, and then the average value is calculated, and the average value is used as the detection result of the detection cycle.

[0051] Specifically, Figure 3 As shown, after the air conditioner and the load sensor are turned on, the load sensor will perform a weight test at a preset frequency, such as every t time, based on a set detection cycle, such as a duration of T. Taking the case of just after it is turned on, the real-time weight Cn (n=1,2,3...,T / t) of the filter is recorded. After obtaining all the real-time weights in the first detection cycle, the highest and lowest values ​​are removed, and the remaining data are averaged to obtain the detection result of the detection cycle, that is, the real-time weight M1 of the filter corresponding to the detection cycle. This can ensure the accuracy of the measurement results.

[0052] After completing a detection cycle, based on the detection cycle interval length, such as after N, the load sensor will repeat the above process to perform detection in a cycle until a certain measured data Mx (x=1,2,3...), that is, the detection result of the Xth detection cycle is greater than the set preset weight threshold C, the load sensor will send a signal to the controller, and the controller will start to activate the buzzer to sound an alarm and determine whether to start dust removal.

[0053] Figure 4 FIG. 1 is a flow chart of a dust removal method for an air conditioner filter provided by another embodiment of the present invention. Figure 4 As shown, in some embodiments of the present application, whether to start dust removal can be determined through the interaction between the controller and the user terminal such as a mobile phone APP and a remote control.

[0054] Specifically, Figure 4As shown, when a certain measured data Mx (x=1,2,3...), that is, the detection result of the Xth detection cycle, is greater than the preset weight threshold C, the load sensor sends a signal to the controller, and the controller starts to activate the buzzer to sound an alarm. The controller can send a signal to the air conditioner remote control and the mobile phone app. The user can view the measurement result of the load sensor, that is, the detection result, on the app, and can choose whether to turn on the filter self-cleaning mode, that is, choose whether to start dust removal.

[0055] If the self-cleaning mode is not turned on (that is, the user does not send dust removal instructions to the controller or electrostatic precipitator through the mobile app or air conditioner remote control), the load sensor will continue to measure and send the test results to the controller. The controller will also send the results to the air conditioner remote control and mobile app, but the buzzer will not be activated until the next time the air conditioner is turned on and an abnormal test result occurs.

[0056] If the self-cleaning mode is turned on (that is, the user sends a dust removal command to the controller or directly to the electrostatic precipitator through a mobile phone app or air conditioner remote control. When the user sends a dust removal command directly to the electrostatic precipitator through a mobile phone app or air conditioner remote control, the electrostatic precipitator can also transmit the corresponding signal to the controller after startup), at this time, start the electrostatic precipitator to remove dust.

[0057] Specifically, in the present application, the evaporator serves as a dust collecting electrode and is connected to the positive electrode of a high-voltage static power source so that it is positively charged. The corona electrode is located between the panel, the panel body and the filter and is negatively charged because it is connected to the negative electrode of the high-voltage static power source. In a high-voltage electric field, dust is usually negatively charged.

[0058] At the same time, when the electrostatic precipitator is started, an electrostatic field is formed from the evaporator to the corona electrode. The crossflow blades of the air conditioner will drive the air flow, causing the dust in the filter to enter the air, and the negatively charged dust in the air will move toward the evaporator, and the positively charged dust will move toward the corona electrode. In the end, most of the dust will be concentrated on the evaporator, and only a small part of the dust will be on the corona electrode, so that users do not need to clean the electrostatic precipitator frequently.

[0059] On this basis, when the air conditioner is cooling, the temperature on the evaporator is generally lower than the dew point of water vapor in the air due to the heat exchange of the refrigerant, resulting in condensation and forming condensed water on the surface. The condensed water can carry away the dust on the surface of the evaporator and enter the drain pipe for discharge, thereby achieving the purpose of self-cleaning and dust removal.

[0060] The air conditioner filter dust removal method provided by the present application solves the problem that the dust accumulation of the air conditioner filter is difficult to determine. By connecting the load sensor to the air conditioner filter, when the load sensor detects that the gravity (corresponding weight) of the filter has changed to a certain extent, a signal is sent to the controller. The controller controls the buzzer to alert the user to clean the filter on the one hand, and sends the detection result to the air conditioner remote control and mobile phone app on the other hand, so that the user can check the dust accumulation degree of the filter in time and determine whether to start dust removal. At the same time, in order to solve the problem that manual cleaning of the filter is time-consuming and laborious and may cause damage to the filter, the present application installs an electrostatic precipitator at the junction of the panel and the panel body of the air conditioner, connects the evaporator as the dust collecting electrode to the positive electrode of the high-voltage static power source, and connects the negative electrode of the high-voltage static power source to the corona electrode at the junction of the panel and the panel body of the air conditioner, so that the electrostatic precipitator forms an electrostatic field during the operation of the air conditioner to gather negatively charged dust particles on the dust collecting electrode, i.e., the evaporator, thereby playing an automatic dust cleaning role. The user can choose whether to turn on the electrostatic precipitator for dust removal at any time on the app.

[0061] Based on the same inventive concept, the present application also provides an air conditioning filter dust removal system, such as Figure 2 As shown, it includes: a load sensor, a controller (which can be implemented through the existing control module of the air conditioner such as a panel and a corresponding module or circuit) and an air conditioner evaporator; wherein the load sensor is arranged at the air conditioner filter, and is used to detect the real-time weight of the air conditioner filter; and to judge the size of the real-time weight and a preset weight threshold; the controller is used to issue an alarm when the real-time weight is greater than the preset weight threshold, and to remove dust through an electrostatic precipitator arranged at the air conditioner evaporator.

[0062] Regarding the system in the above embodiment, the specific manner in which each part performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.
