Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically providing a method, device, and air conditioner for reminding users to clean their filters. Background Technology

[0002] Due to prolonged operation, fine dust and dirt accumulate on the formaldehyde removal filter of air conditioners. A clogged filter reduces formaldehyde removal efficiency, increases energy consumption, and, more importantly, breeds bacteria, mold, and unpleasant odors. When the air conditioner is running, these bacteria quickly spread into the indoor air, coming into contact with people's skin and respiratory tract, easily causing various illnesses. Research shows that many consumers still neglect their air conditioner filters and do not clean them regularly, leading to dust and clogging.

[0003] Existing methods for detecting and cleaning air filters mainly rely on controlling the air conditioner to operate at a high fan speed to assess the degree of filter clogging. This approach has significant limitations, poor accuracy, and fails to meet the actual needs of users.

[0015] In one specific embodiment, it further includes: when the filter needs cleaning, controlling the air conditioner's panel to display a reminder message and illuminate a light; and / or

[0036] Currently, the traditional method for testing and cleaning air filters mainly involves controlling the air conditioner to operate at a high fan speed to detect the degree of filter clogging. This method has significant limitations, poor detection accuracy, and is difficult to meet the actual needs of users.

[0037] To address this issue, this application proposes a filter cleaning reminder method, device, and air conditioner. First, the actual pressure difference across the air conditioner's filter is detected. Second, the current airflow mode and air guide angle of the air conditioner are obtained. Next, a pressure difference threshold is obtained based on the current airflow mode and air guide angle. Finally, it is determined whether the actual pressure difference across the filter exceeds the pressure difference threshold. If it does, the filter needs to be cleaned; otherwise, cleaning is not required. Thus, regardless of the airflow mode and air guide angle, the need for filter cleaning can be determined by detecting the pressure difference across the filter, thereby reminding the user. This improves the accuracy of the filter cleaning reminder and enhances user satisfaction.

[0038] See appendix Figure 1 , Figure 1 This is a schematic flowchart of the main steps of a filter cleaning reminder method according to an embodiment of the present invention.

[0039] like Figure 1 As shown, the filter cleaning reminder method in this embodiment of the invention mainly includes the following steps S101-S104.

[0040] Step S101: Detect the actual pressure difference across the air conditioner's filter.

[0041] The air conditioner filter in this application can be a filter used to remove formaldehyde.

[0042] Generally, pressure sensors need to be installed on both sides of the air conditioner's filter to detect the pressure difference before and after the airflow passes through the filter.

[0043] For example, such as Figure 2 The pressure measuring device shown can detect the pressure difference change of airflow before and after passing through the filter.

[0044] Step S102: Obtain the current air supply mode and air guide plate angle of the air conditioner.

[0045] The air supply modes can include low-level air supply mode, medium-level air supply mode, and high-level air supply mode.

[0046] The air guide plate angle refers to the rotation angle of the air guide plate relative to its current position when it is closed.

[0047] Specifically, it can collect the current air supply mode and air guide angle of the air conditioner in real time.

[0048] Step S103: Obtain the differential pressure threshold based on the current air supply mode of the air conditioner and the angle of the air guide plate.

[0049] In one specific implementation, obtaining the differential pressure threshold based on the current air supply mode of the air conditioner and the angle of the air guide plate includes: obtaining the differential pressure threshold based on the correspondence between the current air supply mode of the air conditioner, the angle of the air guide plate, and the differential pressure threshold.

[0050] By obtaining the current differential pressure threshold based on the correspondence between the air conditioner's current air supply mode and the air guide plate angle and the differential pressure threshold, technical support is provided for judging the filter's clogging status under any air supply mode and air guide plate angle.

[0051] In this embodiment, a complete database can be established by pre-testing the pressure difference across the air filter of all air conditioners under various combinations of air supply modes and air deflector angles. When a user uses the air conditioner, the current air supply mode and air deflector angle are automatically detected. Then, the corresponding pressure difference threshold is retrieved from the database using the detected current air supply mode and air deflector angle, which serves as the standard for determining whether the filter needs cleaning.

[0052] Step S104: Determine whether the actual pressure difference across the filter screen is greater than the pressure difference threshold. If yes, the filter screen needs to be cleaned; otherwise, the filter screen does not need to be cleaned.

[0053] Specifically, the actual pressure difference across the filter screen is compared with a pressure difference threshold. If the actual pressure difference across the filter screen is greater than the pressure difference threshold, the filter screen needs to be cleaned. If the actual pressure difference across the filter screen is less than or equal to the pressure difference threshold, the filter screen does not need to be cleaned.

[0054] Based on steps S101-S104 above, the actual pressure difference across the air conditioner's filter is first detected. Next, the current airflow mode and air guide angle of the air conditioner are obtained. Then, a pressure difference threshold is obtained based on the current airflow mode and air guide angle. Finally, it is determined whether the actual pressure difference across the filter exceeds the pressure difference threshold. If it does, the filter needs to be cleaned; otherwise, cleaning is not required. In this way, regardless of the airflow mode and air guide angle, the system can determine whether the filter needs cleaning by detecting the pressure difference across it, thus reminding the user. This improves the accuracy of the filter cleaning determination and enhances user satisfaction.

[0055] In one specific implementation, the method further includes: determining the degree of clogging of the filter screen based on a differential pressure threshold, wherein the degree of clogging includes mild clogging, moderate clogging, and severe clogging.

[0056] The degree of clogging refers to the time since the last cleaning of the filter. For example, a filter that is less than 20 days old is considered lightly clogged; a filter that is more than 20 days but less than 30 days old is considered moderately clogged; and a filter that is more than 30 days old is considered heavily clogged.

[0057] Specifically, in addition to storing the pressure difference across the air conditioner's filter screen under all air supply modes and air guide plate angle combinations, the database also stores the correspondence between pressure difference and degree of clogging. Therefore, after obtaining the pressure difference threshold based on the aforementioned embodiment, the current degree of clogging of the filter screen can also be obtained based on the pressure difference threshold.

[0058] After obtaining the degree of dirt and clogging of the air conditioner, it can be sent to the user's mobile device, allowing the user to know the current degree of dirt and clogging of the air conditioner's filter in a timely manner so that the user can clean the filter in time.

[0059] In one specific embodiment, this application will take a 45° air guide plate angle and a high-level air supply mode of the air conditioner as an example to provide a detailed description of the filter cleaning reminder method.

[0060] like Figure 3 As shown, you can first adjust the air deflector angle of the air conditioner to 45° and adjust the air supply mode of the air conditioner to the high-level air supply mode.

[0061] The differential pressure threshold is obtained based on the air deflector angle and high-level airflow mode of the air conditioner. Generally, the differential pressure threshold corresponding to the air deflector angle and high-level airflow mode is 33 Pa. After the air conditioner stabilizes, the actual differential pressure across the air conditioner's filter is then measured.

[0062] After detecting the actual pressure difference across the air conditioner's filter, this actual pressure difference can be compared with a pressure difference threshold. Specifically, if the actual pressure difference is greater than 33 Pa, the filter needs to be cleaned; if the actual pressure difference across the filter is less than or equal to 33 Pa, the filter does not need to be cleaned.

[0063] Thus, with the air guide plate angle at 45° and the air conditioner in high-level air supply mode, it is possible to determine whether the filter needs to be cleaned by detecting the pressure difference on both sides of the filter, thereby improving the accuracy of the judgment on whether the filter needs to be cleaned.

[0064] In one specific implementation, it further includes: when the air guide plate is in swing mode, stopping the detection of the actual pressure difference on both sides of the air conditioner's filter.

[0065] Since measuring the actual pressure difference across the air conditioner's filter requires a stable testing environment, it's recommended to measure the actual pressure difference after the air conditioner has been running stably. If the air deflector is in swing mode, stop measuring the actual pressure difference across the filter, and the filter cleaning reminder process will not be executed in this case.

[0066] In one specific embodiment, the method further includes: when the filter needs to be cleaned, sending a reminder message to the user's mobile terminal to remind the user to clean the filter.

[0067] Based on the foregoing embodiments, if it is determined that the filter needs to be cleaned, a reminder message can be sent to the user's mobile terminal to remind the user to clean the filter.

[0068] For example, specific reminder messages could include prompts such as "The air conditioner's filter is heavily clogged; please clean it as soon as possible."

[0069] In one specific embodiment, the method further includes: when the filter needs to be cleaned, controlling the air conditioner panel to display a reminder message and turn on a light; and / or sending a voice prompt message to remind the user to clean the filter.

[0070] Those skilled in the art will understand that, based on the foregoing embodiments, when it is determined that the filter needs to be cleaned, in addition to sending a reminder message to the user's mobile terminal, a reminder message can also be displayed on the air conditioner's panel and a light can be turned on.

[0071] In addition, voice prompts can be sent to remind users to clean the filter.

[0072] The filter cleaning reminder method in this application can determine the filter's clogging status at any setting and air guide angle.

[0073] Specifically, this could involve pre-testing the pressure difference for all combinations of air conditioning settings and deflector angles to establish a comprehensive database. When a user uses the air conditioner, the system automatically detects the current airflow mode and deflector angle, then retrieves the pressure difference calibration data from the database that matches the airflow mode and deflector angle to determine if the filter needs cleaning. If cleaning is required, a reminder message is sent to the user's mobile device, or a reminder message is displayed on the air conditioner's panel with an indicator light to alert the user.

[0074] Those skilled in the art will understand that the air conditioner filter cleanliness detection in this application is fully intelligent. When the air conditioner is running in the fixed air guide mode, regardless of the current air supply level, the air conditioner can automatically perform differential pressure detection and filter cleanliness detection. After comparing it with the corresponding pressure threshold in the database, it will give the user a cleaning reminder when the filter needs to be cleaned. Specifically, the reminder can be a display screen, voice, indicator light, etc.

[0075] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effects of the present invention, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the scope of protection of the present invention.

[0076] Furthermore, the present invention also provides a filter cleaning reminder device.

In some embodiments, the detection module 11 can be configured to detect the actual pressure difference across the air conditioner's filter. The first acquisition module 12 can be configured to acquire the air conditioner's current air supply mode and the angle of the air guide plate. The second acquisition module 13 can be configured to acquire a pressure difference threshold based on the air conditioner's current air supply mode and the angle of the air guide plate. The judgment module 14 can be configured to determine whether the actual pressure difference across the filter is greater than the pressure difference threshold; if so, the filter needs to be cleaned; if not, the filter does not need to be cleaned. In one embodiment, a description of the specific functions can be found in steps S101-S104.

[0078] The filter cleaning reminder device of this application first uses a detection module to detect the actual pressure difference across the air conditioner's filter. Next, a first acquisition module acquires the air conditioner's current airflow mode and air guide angle. Then, a second acquisition module acquires a pressure difference threshold based on the air conditioner's current airflow mode and air guide angle. Finally, a judgment module determines whether the actual pressure difference across the filter exceeds the pressure difference threshold. If it does, the filter needs cleaning; otherwise, cleaning is not required. Thus, regardless of the airflow mode and air guide angle, the device can determine whether the filter needs cleaning by detecting the pressure difference across the filter, thereby reminding the user. This improves the accuracy of the filter cleaning determination and enhances user satisfaction.
