[0050] Unless otherwise stated, the term "multiple" means two or more.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0052] Combination Figures 1-7 As shown, this embodiment of the present disclosure provides an indoor air conditioning unit, including: a housing 100 and a functional mesh 200. The housing 100 has a return air vent 110 and a mounting port 120; the functional mesh 200 is movably disposed inside the housing 100 and blocks the flow surface of the return air vent 110; wherein, the mounting port 120 is disposed on the side wall of the housing 100, the functional mesh 200 is installed inside the housing 100 along the mounting port 120, and can be pulled out from inside the housing 100 along the mounting port 120.

[0053] The air conditioner indoor unit provided in this embodiment allows the functional mesh 200 to be installed inside the housing 100 via an installation port 120 on the side wall of the housing 100. When the functional mesh 200 needs to be removed, it can be pulled out from inside the housing 100 via the installation port 120. Since the housing 100 does not need to be opened during installation and removal, the efficiency of installation and removal of the functional mesh 200 is improved, enhancing the user experience.

[0054] Optionally, the return air vent 110 is located on the front and upper sidewalls of the housing 100. This increases the return air area of ​​the return air vent 110 and improves the return air volume.

[0055] Understandably, the indoor unit of this air conditioner is a wall-mounted air conditioner. The casing 100 of the indoor unit is mounted on the wall. The side wall of the casing 100 facing the wall is the rear side wall of the casing 100, and the side wall of the casing 100 facing away from the wall is the front side wall of the casing 100.

[0056] Optionally, the front sidewall of the housing 100 is provided with a panel, which is rotatably connected to the housing 100 and can block part of the return air vent 110. In this way, the panel can open part of the return air vent 110 on the front sidewall of the housing 100, and the internal components of the housing 100 can be inspected and maintained through the return air vent 110.

[0057] Optionally, when the panel is closed, the panel partially blocks the return air inlet 110, and there is a flow gap between the inner wall of the panel and the outer wall of the functional mesh 200. In this way, the return airflow in the return air inlet 110 can flow and diffuse through the flow gap to the entire outer wall area of ​​the functional mesh 200, and the return airflow passes through the functional mesh 200 evenly, improving the treatment effect of the return airflow.

[0058] Optionally, the mounting port 120 is located on the side wall of the housing 100 corresponding to one side of the return air vent 110 along its length. The functional mesh 200 is installed inside the housing 100 through the mounting port 120 along the length of the return air vent 110, or pulled out of the housing 100 through the mounting port 120. This allows for installation and removal of the functional mesh 200 from one side of the housing 100, eliminating the need to be at the front. Since dust may adhere to the functional mesh 200, removing it from the side of the housing 100 reduces the spread of dust to the user's face. Furthermore, since the removal of the functional mesh 200 may occur while the indoor unit of the air conditioner is running, installing and removing the functional mesh 200 from the side of the housing 100 avoids obstruction of the airflow from the indoor unit, reduces the impact of removing the functional mesh 200 on the airflow effect, and prevents discomfort caused by direct hot or cold airflow onto the user.

[0059] Understandably, since the indoor unit of this air conditioner is a wall-mounted air conditioner, the length of the casing 100 is horizontal, the length of the return air vent 110 is also horizontal, the air outlet is located on the lower side wall of the casing 100, and the mounting port 120 is opened on one side wall of the casing 100 along its length.

[0060] Optionally, the shape of the mounting port 120 is adapted to the shape of the end of the functional mesh 200 along its length. This ensures that the functional mesh 200 can be smoothly installed and removed through the mounting port 120, while also preventing the mounting port 120 from being too large, which would lead to poor sealing of the housing 100 and affect the cooling and heating performance.

[0061] Optionally, the indoor unit of the air conditioner further includes a mounting base 300 and a sealing base 400. One side of the functional mesh 200 is embedded within the mounting base 300; the sealing base 400 is disposed at one end of the functional mesh 200 and connected to the end of the mounting base 300. When the functional mesh 200 is installed inside the housing 100 along the mounting opening 120, the mounting base 300 is installed inside the housing 100 along with the functional mesh 200, and the sealing base 400 is embedded in the mounting opening 120, sealing the mounting opening 120. Thus, since the functional mesh 200 has low rigidity and is prone to deformation during installation and disassembly, leading to blockage of the mounting opening 120, the mounting base 300 is provided to install the functional mesh 200, improving its rigidity and making installation and disassembly of the functional mesh 200 smoother. The sealing seat 400 can cooperate with the mounting seat 300 to more smoothly install and remove the functional net 200. At the same time, the sealing seat 400 can block the installation port 120, eliminating the need to set a sealing structure for the installation port 120 and reducing costs.

[0062] Optionally, the lower side of the functional mesh 200 is embedded in the mounting base 300. In this way, while improving the installation and disassembly strength of the functional mesh 200 through the mounting base 300, the obstruction of the functional mesh 200 by the mounting base 300 is reduced, and the impact of the mounting base 300 on the effect of the functional mesh 200 on the handling of return airflow is reduced.

[0063] Optionally, the sealing seat 400 is located at the end of the functional mesh 200 facing the mounting opening 120. Thus, since the functional mesh 200 is installed and removed along the mounting opening 120, by positioning the sealing seat 400 at the end of the functional mesh 200 facing the mounting opening 120, the sealing seat 400 can move into the mounting opening 120 to seal the functional mesh 200 when it is installed inside the housing 100.

[0064] Optionally, the shape of the sealing seat 400 is adapted to the shape of the mounting port 120. In this way, the sealing seat 400 can move smoothly into the mounting port 120 to seal it.

[0065] Optionally, there is a gap between the end of the functional mesh 200 facing the mounting opening 120 and the sealing seat 400. Thus, when the functional mesh 200 is pulled out along the mounting groove, the sealing seat 400 is pulled out first from the mounting opening 120. The user's fingers can be inserted into the gap formed between the sealing seat 400 and the functional mesh 200, allowing the sealing seat 400 to act as a handle, facilitating the user's effort to pull out the mounting seat 300 and the functional mesh 200.

[0066] Optionally, a guide rail 130 is provided on the inner wall of the housing 100 corresponding to the lower side of the return air vent 110, and the mounting base 300 is slidably embedded in the guide rail 130. In this way, the guide rail 130 can guide the mounting base 300, so that the mounting base 300 can slide in the direction toward or away from the mounting opening 120 during installation and removal, thereby ensuring that the functional mesh 200 embedded in the mounting base 300 can slide in the direction toward or away from the mounting opening 120, reducing the risk of the functional mesh 200 shifting during installation and removal.

[0067] Optionally, the end of the functional mesh 200 facing away from the mounting port 120 is provided with a positioning groove 140 on the inner wall of the housing 100. When the functional mesh 200 is installed inside the housing 100, the end of the functional mesh 200 facing away from the mounting port 120 is embedded in the positioning groove 140. In this way, the positioning groove 140 can position the end of the functional mesh 200 facing away from the mounting port 120, improving the accuracy of the installation of the functional mesh 200. After installation, the functional mesh 200 can accurately block the return air vent 110 and treat the return airflow.

[0068] Optionally, a rack 310 is provided on one side wall of the mounting base 300, and a drive mechanism 150 is provided inside the housing 100. The drive mechanism 150 meshes with the rack 310 to drive the mounting base 300 to extend or retract into the housing 100 along the mounting opening 120. Thus, by providing the drive mechanism 150 inside the housing 100 to drive the movement of the mounting base 300, the functional mesh 200 is extended or retracted into the housing 100 via the mounting base 300, improving the efficiency of installing and removing the functional mesh 200. When the functional mesh 200 needs to be removed, the drive mechanism 150 drives the mounting base 300 to extend into the housing 100 along the mounting opening 120. When the functional mesh 200 needs to be installed, the lower side of the functional mesh 200 is first embedded inside the mounting base 300, and then the drive mechanism 150 drives the mounting base 300 to retract into the housing 100 along the mounting opening 120.

[0069] Optionally, the drive mechanism 150 is disposed on the inner wall of the housing 100 corresponding to the end of the guide rail 130 facing the mounting port 120. In this way, since the mounting base 300 is slidably embedded in the guide rail 130 and extends or retracts into the housing 100 along the mounting port 120 under the guidance of the guide rail 130, placing the drive mechanism 150 between the end of the guide rail 130 and the mounting port 120 can increase the length of the mounting base 300 extending out of the mounting port 120, which facilitates the installation and removal of the functional mesh 200.

[0070] Optionally, the drive mechanism 150 includes a stepper motor, the output of which meshes with the rack 310.

[0071] Optionally, the outer wall of the mounting base 300 is provided with a rack 310, which extends along the length of the mounting base 300 and has the same length as the mounting base 300. This increases the drive stroke of the mounting base 300, allowing the mounting base 300 to extend a wider range out of the housing 100 along the mounting opening 120, facilitating the installation and removal of the functional mesh 200.

[0072] Optionally, a distance sensor 500 is provided inside the housing 100, located at the other end of the functional net 200. In this way, the distance sensor 500 can detect the installation depth of the functional net 200, thereby determining whether the functional net 200 is installed correctly or not, improving the installation accuracy of the functional net 200.

[0073] Optionally, the distance sensor 500 is disposed within the positioning groove 140. Thus, when the functional mesh 200 is installed inside the housing 100, the end of the functional mesh 200 facing away from the mounting opening 120 is embedded in the positioning groove 140. Therefore, by disposing the distance sensor 500 within the positioning groove 140, the distance between the end of the functional mesh 200 and the positioning groove 140 can be detected, thereby more accurately determining whether the functional mesh 200 is properly installed, or whether the functional mesh 200 is installed at all.

[0074] Combination Figures 8-10 As shown, in one embodiment, the functional mesh 200 includes: a filter mesh 210, or a formaldehyde removal mesh 220, or a fragrance mesh 230.

[0075] Combination Figure 8 As shown, in one specific embodiment, the functional net 200 includes a filter 210. Thus, when the functional net 200 includes a filter 210, it can filter dust and other impurities in the return airflow, improving the cleanliness of the return airflow and enhancing the air quality of the indoor environment.

[0076] Combination Figure 9 As shown, in another specific embodiment, the functional net 200 includes a formaldehyde removal net 220. Thus, when the functional net 200 includes the formaldehyde removal net 220, the functional net 200 can absorb formaldehyde from the return airflow. Since the indoor air is circulated through the indoor unit of the air conditioner, the indoor air is gradually purified by the formaldehyde removal net 220, improving the indoor air quality.

[0077] Combination Figure 10As shown, in another specific embodiment, the functional network 200 includes a fragrance network 230. Thus, when the functional network 200 includes the fragrance network 230, the functional network 200 can provide a fragrance function. When the return airflow passes through the functional network 200, it carries fragrance molecules back into the indoor environment, improving indoor air quality and enhancing the user experience.

[0078] Combination Figures 11-14 As shown, in another embodiment, the functional net 200 includes a filter 210, a formaldehyde removal net 220, and a fragrance net 230. Thus, the functional net 200 simultaneously includes a filter 210, a formaldehyde removal net 220, and a fragrance net 230, enabling it to filter, remove formaldehyde, and fragrance the return airflow at the return air vent 110, improving the treatment effect of the return airflow and improving the air quality in the indoor environment.

[0079] Optionally, filter 210 is located on the windward side of formaldehyde removal net 220, and formaldehyde removal net 220 is located on the windward side of fragrance net 230. In this way, the return airflow is first filtered by filter 210, then formaldehyde is removed by formaldehyde removal net 220, and then flows through fragrance net 230 for fragrance treatment. This reduces the risk of dust and other impurities in the return airflow clogging formaldehyde removal net 220 and fragrance net 230, and extends the service life of formaldehyde removal net 220 and fragrance net 230.

[0080] Optionally, the positioning groove 140 has a first groove 141, a second groove 142 and a third groove 143. When the functional mesh 200 is installed inside the housing 100, one end of the filter mesh 210 is embedded in the first groove 141, one end of the formaldehyde removal mesh 220 is embedded in the second groove 142, and one end of the fragrance mesh 230 is embedded in the third groove 143.

[0081] Optionally, the distance sensor 500 includes a first sensor 510, a second sensor 520, and a third sensor 530; the first sensor 510 is disposed in the first groove 141, the second sensor 520 is disposed in the second groove 142, and the third sensor 530 is disposed in the third groove 143; the first sensor 510 is used to detect the installation depth of the filter screen 210, the second sensor 520 is used to detect the installation depth of the formaldehyde removal screen 220, and the third sensor 530 is used to detect the installation depth of the fragrance screen 230.

[0082] Combination Figures 15-20 As shown, in another embodiment, the functional mesh 200 includes any two of the following: filter mesh 210, formaldehyde removal mesh 220, and fragrance mesh 230.

[0083] Combination Figure 15 and Figure 16As shown, in one specific embodiment, the functional mesh 200 includes a filter mesh 210 and a formaldehyde removal mesh 220. Thus, with the functional mesh 200 including the filter mesh 210 and the formaldehyde removal mesh 220, the return airflow can be filtered and treated to remove formaldehyde.

[0084] For example, the positioning groove 140 has a first groove portion 141 and a second groove portion 142. The distance sensor 500 includes a first sensor 510 and a second sensor 520. The first sensor 510 is installed in the first groove portion 141, and the second sensor 520 is installed in the second groove portion 142. When the functional mesh 200 includes a filter mesh 210 and a formaldehyde removal mesh 220, one end of the filter mesh 210 is embedded in the first groove portion 141, and one end of the formaldehyde removal mesh 220 is embedded in the second groove portion 142. The first sensor 510 is used to detect the installation depth of the filter mesh 210, and the second sensor 520 is used to detect the installation depth of the formaldehyde removal mesh 220.

[0085] Combination Figure 17 and Figure 18 As shown, in another specific embodiment, the functional mesh 200 includes a filter mesh 210 and a fragrance mesh 230. Thus, when the functional mesh 200 includes both the filter mesh 210 and the fragrance mesh 230, the return airflow can be filtered and fragranced.

[0086] For example, the positioning groove 140 has a first groove portion 141 and a second groove portion 142. The distance sensor 500 includes a first sensor 510 and a second sensor 520. The first sensor 510 is installed in the first groove portion 141, and the second sensor 520 is installed in the second groove portion 142. When the functional mesh 200 includes a filter mesh 210 and a fragrance mesh 230, one end of the filter mesh 210 is embedded in the first groove portion 141, and one end of the fragrance mesh 230 is embedded in the second groove portion 142. The first sensor 510 is used to detect the installation depth of the filter mesh 210, and the second sensor 520 is used to detect the installation depth of the fragrance mesh 230.

[0087] Combination Figure 19 and Figure 20 As shown, in another specific embodiment, the functional net 200 includes a formaldehyde removal net 220 and a fragrance net 230. Thus, when the functional net 200 includes both the formaldehyde removal net 220 and the fragrance net 230, the return airflow can be treated for formaldehyde removal and fragrance.

[0088] For example, the positioning groove 140 has a first groove portion 141 and a second groove portion 142. The distance sensor 500 includes a first sensor 510 and a second sensor 520. The first sensor 510 is installed in the first groove portion 141, and the second sensor 520 is installed in the second groove portion 142. When the functional mesh 200 includes a formaldehyde removal mesh 220 and a fragrance mesh 230, one end of the formaldehyde removal mesh 220 is embedded in the first groove portion 141, and one end of the fragrance mesh 230 is embedded in the second groove portion 142. The first sensor 510 is used to detect the installation depth of the formaldehyde removal mesh 220, and the second sensor 520 is used to detect the installation depth of the fragrance mesh 230.

[0089] Combination Figure 1 and Figure 21 As shown, in some embodiments, the indoor unit of the air conditioner further includes a controller 600. The controller 600 is disposed on one side of the housing 100 and is used to acquire the operating parameters of the indoor unit of the air conditioner, and determine whether the functional network 200 needs maintenance based on the operating parameters. In this way, the controller 600 accurately determines the wear and tear of the functional network 200 based on the acquired operating parameters of the indoor unit of the air conditioner.

[0090] Optionally, the operating parameters of the indoor unit of the air conditioner include: the power-on time of the indoor unit or the operating time of the fan of the indoor unit. In this way, the power-on time or the operating time of the fan of the indoor unit can accurately reflect the usage time of the functional network 200, thereby making it easier for the controller 600 to more accurately judge the wear and tear of the functional network 200.

[0091] Optionally, when the operating parameters include the power-on duration of the indoor unit, the controller 600 determines whether the functional network 200 requires maintenance based on the operating parameters. This includes: if the power-on duration is greater than or equal to a first set duration, the controller 600 determines that the functional network 200 requires maintenance; if the power-on duration is less than the first set duration, the controller 600 determines that the functional network 200 does not require maintenance. In this way, the power-on duration of the indoor unit accurately reflects its usage time. When the power-on duration is greater than or equal to the first set duration, the controller 600 indicates that the functional network 200 has been used for a longer period and requires maintenance. When the power-on duration is less than the first set duration, the controller 600 indicates that the functional network 200 has been used for a shorter period and does not require maintenance.

[0092] Optionally, the first set duration is 2150 hours.

[0093] Optionally, when the operating parameters include the operating time of the indoor unit's fan, the controller 600 determines whether the functional network 200 needs maintenance based on the operating parameters. This includes: if the fan's operating time is greater than or equal to a second set time, the controller 600 determines that the functional network 200 needs maintenance; if the fan's operating time is less than the second set time, the controller 600 determines that the functional network 200 does not need maintenance. Thus, the use of the functional network 200 inevitably involves the operation of the fan, therefore, the controller 600's determination of whether the functional network 200 needs maintenance is more accurate by obtaining the fan's operating time. When the fan's operating time is greater than or equal to the second set time, the controller 600 determines that the functional network 200 has a longer operating time, thus requiring maintenance. When the fan's operating time is less than the second set time, the controller 600 determines that the functional network 200 has a shorter operating time, thus requiring maintenance.

[0094] Optionally, when the functional mesh 200 is a filter 210, the second set duration is 250 hours; when the functional mesh 200 is a formaldehyde removal mesh 220, the second set duration is 1000 hours; and when the functional mesh 200 is a fragrance mesh 230, the second set duration is 700 hours. Thus, since the filter 210, formaldehyde removal mesh 220, and fragrance mesh 230 have different maintenance times, the second set duration varies depending on the functional mesh 200.

[0095] Understandably, the methods for obtaining the power-on time of the indoor unit and the running time of the fan will not be elaborated here.

[0096] Optionally, the controller 600 is also used to issue a prompt message to the user when the functional network 200 requires maintenance. In this way, when the controller 600 determines that the functional network 200 needs maintenance, it issues a prompt message to the user, making it easier for the user to understand the wear and tear of the functional network 200 in a timely manner.

[0097] Optionally, the controller 600 sends a prompt message to the user, including: the controller 600 controls the user's mobile terminal to send a prompt message to the user.

[0098] For example, mobile terminals include mobile phones, tablets, smartwatches, etc.

[0099] Optionally, the controller 600 is further configured to determine the relationship between the power-on duration and a third preset duration when the operating parameters include the power-on time of the indoor unit of the air conditioner, and the functional network 200 requires maintenance. If the power-on duration is greater than or equal to the third preset duration, the controller 600 controls the functional network 200 to extend out of the housing 100 along the mounting port 120, wherein the third preset duration is greater than the first preset duration. Thus, when the power-on duration is greater than or equal to the third preset duration, the functional network 200 is experiencing significant wear and tear and urgently requires maintenance. Therefore, the controller 600 controls the functional network 200 to extend out of the housing 100 along the mounting port 120, allowing the user to efficiently remove the functional network 200 for maintenance.

[0100] Optionally, the third setting is a duration of 4300 hours.

[0101] Optionally, the controller 600 is further configured to, when operating parameters include the fan's operating time and the functional network 200 requires maintenance, determine the relationship between the operating time and a fourth preset time. If the operating time is greater than or equal to the fourth preset time, the controller controls the functional network 200 to extend out of the housing 100 along the mounting port 120, wherein the fourth preset time is greater than the second preset time. Thus, when the fan's operating time is greater than or equal to the fourth preset time, the functional network 200 is severely worn and requires urgent maintenance. Therefore, the controller 600 controls the functional network 200 to extend out of the housing 100 along the mounting port 120, allowing the user to efficiently remove the functional network 200 for maintenance.

[0102] Optionally, when the functional mesh 200 is a filter mesh 210, the fourth setting time is 500 hours; when the functional mesh 200 is a formaldehyde removal mesh 220, the fourth setting time is 2000 hours; and when the functional mesh 200 is a fragrance mesh 230, the fourth setting time is 1400 hours.

[0103] Optionally, the controller 600 controls the functional mesh 200 to extend out of the housing 100 along the mounting port 120, including: the controller 600 controls the functional mesh 200 to extend out of the housing 100 by a preset distance along the mounting port 120. This allows the user to easily pull out the functional mesh 200 along the mounting port 120 while retaining the ability to handle return airflow and maintain air quality.

[0104] Optionally, the preset distance is 20 mm.

[0105] Optionally, the controller 600 controls the functional net 200 to extend out of the housing 100 along the mounting port 120, including: the controller 600 controls the drive mechanism 150 to drive the mounting base 300 to extend out of the housing 100 along the mounting port 120, thereby causing the functional net 200 to extend out of the housing 100 along the mounting port 120.

[0106] Optionally, while the controller 600 controls the functional network 200 to extend out of the housing 100 along the mounting port 120, it also includes: the controller 600 periodically sending a reminder message to the user, with a period interval of 72 hours. Thus, when the controller 600 controls the functional network 200 to extend, the functional network 200 is at a relatively high level of wear and tear, thus requiring immediate disassembly and maintenance by the user. To prevent the user from ignoring the reminder message, the controller 600 periodically sends a reminder message to the user.

[0107] In some embodiments, before the controller 600 acquires the operating parameters of the indoor unit of the air conditioner, the method further includes: the controller 600 acquiring the installation distance between the functional network 200 and the distance sensor 500, and determining that the installation distance is less than or equal to a first preset distance. Thus, when the installation distance of the functional network 200 is less than or equal to the first preset distance, the functional network 200 is in place, and the controller 600 acquires the operating parameters of the indoor unit of the air conditioner under these conditions to make a more accurate judgment on whether the functional network 200 needs maintenance.

[0108] Understandably, the installation distance between the functional net 200 and the distance sensor 500 refers to the distance between the end of the functional net 200 facing the distance sensor 500 and the distance sensor 500 along the direction of movement of the functional net 200.

[0109] Optionally, when the functional mesh 200 includes a filter mesh 210, a formaldehyde removal mesh 220, and a fragrance mesh 230, the controller 600 acquires the installation distance between the functional mesh 200 and the distance sensor 500, including: the controller 600 simultaneously acquires the installation distance between the filter mesh 210, the formaldehyde removal mesh 220, and the fragrance mesh 230 and the corresponding distance sensor 500, and determines that each installation distance is less than or equal to a first preset distance.

[0110] Optionally, the first setting spacing is 5 mm.

[0111] In some embodiments, the controller 600 obtains the installation distance between the functional network 200 and the distance sensor 500. If the installation distance is greater than a first preset distance and less than or equal to a second preset distance, the controller sends a prompt message to the user indicating that the functional network 200 is not installed correctly. Thus, when the installation distance is greater than the first preset distance and less than or equal to the second preset distance, the functional network 200 is not installed correctly, which will affect the processing effect of the return airflow; therefore, a prompt message is sent to the user indicating that the functional network 200 is not installed correctly.

[0112] Optionally, when the functional network 200 includes a filter 210, a formaldehyde removal mesh 220, and a fragrance mesh 230, the controller 600 acquires the installation distance between the functional network 200 and the distance sensor 500. This includes: the controller 600 simultaneously acquires the installation distances between the filter 210, the formaldehyde removal mesh 220, and the fragrance mesh 230 and their corresponding distance sensors 500, and if any installation distance is greater than a first preset distance and less than or equal to a second preset distance, a prompt message is sent to the user indicating that the functional network 200 is not properly installed. Thus, when the functional network 200 includes a filter 210, a formaldehyde removal mesh 220, and a fragrance mesh 230, if any one of these is not properly installed, it will affect the processing effect of the return airflow; therefore, the controller 600 sends a prompt message to the user.

[0113] Optionally, the controller 600 periodically sends a notification to the user that the functional network 200 is not properly installed, with a period interval of 48 hours. Since improper installation of the functional network 200 can affect indoor air quality, the controller 600 periodically sends this notification to the user to prevent them from ignoring the notification.

[0114] Optionally, the second setting spacing is 30 mm.

[0115] Optionally, if the installation spacing is greater than the second preset spacing, the controller 600 determines that the functional network 200 is not installed and de-energizes the distance sensor 500. Thus, when the installation spacing is greater than the second preset spacing, the functional network 200 is considered not installed, and the distance sensor 500 is de-energized, saving energy.

[0116] Optionally, when the controller 600 controls the distance sensor 500 to power off, the controller 600 will no longer execute the above control logic.

[0117] Optionally, when the functional mesh 200 includes a filter mesh 210, a formaldehyde removal mesh 220, and a fragrance mesh 230, the controller 600 determines the installation spacing that is greater than the second set spacing among multiple installation spacings as the target installation spacing, and determines the target distance sensor 500 corresponding to the target installation spacing, and controls the target distance sensor 500 to be powered off.

[0118] For example, the distance sensor 500 corresponding to the filter 210 is the first sensor 510, the distance sensor 500 corresponding to the formaldehyde removal net 220 is the second sensor 520, and the distance sensor 500 corresponding to the fragrance net 230 is the third sensor 530. The controller 600 obtains the installation spacing of the filter 210 as the first installation spacing, the installation spacing of the formaldehyde removal net 220 as the second installation spacing, and the installation spacing of the fragrance net 230 as the third installation spacing. If the first installation spacing is greater than the second set spacing, the first installation spacing is determined to be the target installation spacing, and the corresponding target distance sensor 500 is determined to be the first sensor 510. At this time, it is considered that the filter 210 is not installed, so the power is turned off to the first sensor 510 corresponding to the filter 210, and the control logic of the filter 210 is no longer executed.
