Abstract

The application provides a control method and device for an aldehyde removal module and an air conditioner. The control method comprises the following steps: when a control device sends a control signal to the air conditioner, the air conditioner enters a cooling mode or a heating mode according to the control signal; before the air conditioner enters the cooling mode or the heating mode, it is judged whether the aldehyde removal module needs to avoid the air inlet according to the indoor temperature; if yes, the driving part is controlled to drive the aldehyde removal module to move to a first preset position which is arranged in a staggered manner with the air inlet; the technical problem solved by the application is that the aldehyde removal module of the existing air conditioner is usually fixedly installed at a position opposite to the air inlet; when the air conditioner is started (such as in the cooling or heating mode), the airflow needs to flow through the aldehyde removal module before entering the air conditioner for heat exchange, which reduces the sectional area of the air inlet passage, causes the air inlet amount to decrease, and prolongs the temperature adjusting time when the air inlet amount is insufficient during the user's urgent need for cooling or heating, thereby affecting the heat exchange efficiency of the air conditioner and the user's use experience.

Description

Technical Field

[0001] This invention relates to the technical field of air conditioners, and more specifically, to a control method, control device, and air conditioner for a formaldehyde removal module. Background Technology

[0002] As society progresses, people have increasingly higher demands for health. Air conditioners, as essential household appliances, are also gradually becoming more health-oriented, with air conditioners equipped with formaldehyde removal modules becoming increasingly popular.

[0003] Air conditioners with formaldehyde removal modules on the market typically have the module installed on the air intake side of the air conditioner, opposite to the air inlet. This ensures that the formaldehyde removal module can filter and purify harmful substances such as formaldehyde in the air before the air enters the air conditioner for circulation, thereby improving the formaldehyde removal effect.

[0004] However, the relevant technology has at least one of the following problems: In the existing technology, the formaldehyde removal module of the air conditioner is usually fixedly installed at the relative position of the air inlet. When the air conditioner is started (such as in cooling or heating mode), the airflow must first flow through the formaldehyde removal module before entering the air conditioner for heat exchange, which reduces the cross-sectional area of ​​the air inlet channel and causes a decrease in air volume. When the user urgently needs to cool down or heat up, insufficient air volume will prolong the temperature adjustment time, affect the heat exchange efficiency of the air conditioner, and thus affect the user experience. Summary of the Invention

[0005] The technical problem solved by this invention is that in the prior art, the formaldehyde removal module of an air conditioner is usually fixedly installed at a position relative to the air inlet. When the air conditioner is started (such as in cooling or heating mode), the airflow must first flow through the formaldehyde removal module before entering the air conditioner for heat exchange, which reduces the cross-sectional area of ​​the air inlet channel and causes a decrease in air volume. When the user urgently needs to cool down or heat up, insufficient air volume will prolong the temperature adjustment time, affect the heat exchange efficiency of the air conditioner, and thus affect the user's experience.

[0006] To solve the above-mentioned technical problems, the present invention provides a control method for a formaldehyde removal module. The formaldehyde removal module is installed at a position opposite to the air inlet of an air conditioner. A drive component for controlling the rotation of the formaldehyde removal module is provided at the connection between the formaldehyde removal module and the air conditioner. The air conditioner is communicatively connected to a control device. The control method includes:

[0007] When the control device sends a control signal to the air conditioner, the air conditioner enters either cooling mode or heating mode according to the control signal.

[0008] Before the air conditioner enters cooling or heating mode, the indoor temperature is obtained, and the indoor temperature is used to determine whether the formaldehyde removal module needs to avoid the air inlet.

[0009] If so, control the driving component to drive the formaldehyde removal module to move to the first preset position which is misaligned with the air inlet;

[0010] If not, control the driving component to drive the formaldehyde removal module to move to the second preset position which is opposite to the air inlet, so that the formaldehyde removal module can carry out formaldehyde removal work on the indoor environment;

[0011] Among them, when the indoor temperature reaches the preset temperature of the air conditioner, control the driving component to drive the formaldehyde removal module to move to the second preset position.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: When the air conditioner receives the control signal sent by the control device, this solution determines whether the formaldehyde removal module needs to avoid the air inlet according to the indoor temperature. If so, control the driving component to drive the formaldehyde removal module to avoid the air inlet. In this way, when the user urgently needs to cool down or heat up, the formaldehyde removal module can avoid the air inlet, enabling the air entering from the air inlet to directly enter the air conditioner for heat exchange and then be blown out from the air outlet. This increases the cross-sectional area of the air inlet channel of the air conditioner, increases the air intake of the air conditioner, and thus improves the heat exchange efficiency of the air conditioner.

[0013] Furthermore, on the one hand, when the formaldehyde removal module avoids the air inlet, this solution controls the driving component to move the formaldehyde removal module to the first preset position which is misaligned with the air inlet to reduce the obstruction of the formaldehyde removal module to the air flow, allowing more air to directly enter the air conditioner. As a result, the heat exchanger inside the air conditioner can contact more air, improving the heat exchange efficiency of the air conditioner. On the other hand, when the formaldehyde removal module does not avoid the air inlet, control the driving component to drive the formaldehyde removal module to move to the second preset position which is opposite to the air inlet, so that the formaldehyde removal module can carry out formaldehyde removal work on the indoor environment, ensuring that the indoor formaldehyde concentration remains at a safe level continuously and guaranteeing the living safety of users.

[0014] In an example of the present invention, before the air conditioner enters the cooling mode, the indoor temperature includes the first indoor temperature. Define the first indoor temperature as T1 and define the first preset temperature of the air conditioner as Ta. Judging whether the formaldehyde removal module needs to avoid the air inlet according to the indoor parameters includes:

[0015] If T1 < Ta, it is determined that the formaldehyde removal module does not need to avoid the air inlet;

[0016] If T1 > Ta, obtain the information on the presence of people in the room and judge whether there is anyone in the room according to the information on the presence of people;

[0017] If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and control the formaldehyde removal module to avoid the air inlet.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Before the air conditioner enters the cooling mode, based on the first indoor temperature in the room and the first preset temperature of the air conditioner, the air conditioner can accurately determine whether it is necessary to adjust the position of the formaldehyde removal module, so as to improve the cooling effect of the air conditioner while ensuring the indoor air quality, thereby enhancing the user experience.

[0019] In an example of the present invention, before the air conditioner enters the heating mode, the indoor temperature includes the first indoor temperature. Define the second indoor temperature as T2 and the second preset temperature of the air conditioner as Tb. According to the indoor temperature, determine whether the formaldehyde removal module needs to avoid the air inlet, and it further includes:

[0020] If T2 > Tb, it is determined that the formaldehyde removal module does not need to avoid the air inlet;

[0021] If T2 < Tb, obtain the information on the presence of people in the room, and based on the information on the presence of people, determine whether there is anyone in the room;

[0022] If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and control the formaldehyde removal module to avoid the air inlet.

[0023] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Before the air conditioner enters the heating mode, based on the second indoor temperature in the room and the second preset temperature of the air conditioner, the air conditioner can accurately determine whether it is necessary to adjust the position of the formaldehyde removal module, so as to improve the heating effect of the air conditioner while ensuring the indoor air quality, thereby enhancing the user experience.

[0024] In an example of the present invention, the control method further includes:

[0025] Before the air conditioner enters the cooling mode or the heating mode, obtain the current first formaldehyde concentration in the room, and define the first formaldehyde concentration as C1;

[0026] If there is someone in the room, based on the magnitude relationship between C1 and Ca, and between C1 and Cb, determine whether the formaldehyde removal module needs to avoid the air inlet;

[0027] When C1 > Ca or Ca > C1 > Cb, it is determined that the formaldehyde removal module does not need to avoid the air inlet, and control the formaldehyde removal module not to avoid the air inlet;

[0028] When C1 < Cb, determine whether the people in the room show human reactions. The human reactions include frequent blinking and / or coughing;

[0029] If a human reaction occurs, it is determined that the formaldehyde removal module does not need to avoid the air inlet;

[0030] If no human reaction occurs, it is determined that the formaldehyde removal module needs to avoid the air inlet, and the drive component is controlled to drive the formaldehyde removal module to avoid the air inlet.

[0031] Where Ca and Cb are preset values, and Ca > Cb.

[0032] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution achieves precise control of the formaldehyde removal module by intelligently judging the indoor formaldehyde concentration and the status of people, ensuring indoor air quality and improving user comfort and safety.

[0033] In one embodiment of the present invention, the air conditioner is equipped with an alarm device for issuing an alarm signal to replace the formaldehyde removal module. When the indoor temperature reaches the preset temperature of the air conditioner, the control method further includes:

[0034] The initial formaldehyde concentration in the room is obtained when the formaldehyde removal module is performing formaldehyde removal work, and the second formaldehyde concentration in the room is obtained after a first time interval.

[0035] The formaldehyde removal rate of the formaldehyde removal module during the first time period is calculated based on the initial formaldehyde concentration and the second formaldehyde concentration.

[0036] Determine whether the formaldehyde removal module meets the alarm conditions based on the historical formaldehyde removal speed and efficiency of the formaldehyde removal module in the past n first time periods.

[0037] If the alarm conditions are met, the alarm device will be controlled to issue an alarm signal.

[0038] Compared to existing technologies, the technical effects achieved by this solution are as follows: This solution predicts the performance degradation of the formaldehyde removal module based on its historical removal rate. This allows the air conditioner to promptly remind users to replace the formaldehyde removal module when it can no longer meet the indoor formaldehyde removal requirements, ensuring that the indoor formaldehyde concentration remains at a safe level, reducing the harm of formaldehyde to the human body, and protecting the safety of users' residences. Furthermore, by calculating the formaldehyde removal rate of the module using the initial and second formaldehyde concentrations, it is possible to accurately determine whether the formaldehyde removal module needs to be replaced, thereby improving the accuracy of the judgment results regarding the performance degradation of the formaldehyde removal module.

[0039] In one embodiment of the present invention, the formaldehyde removal efficiency is defined as V. n+1 Based on the initial formaldehyde concentration and the second formaldehyde concentration, the formaldehyde removal rate of the formaldehyde removal module during the first time period is calculated as follows:

[0040] The formula for calculating the formaldehyde removal rate of the formaldehyde removal module in the first time period is as follows:

[0041] Formula 1: ;

[0042] Where C0 is the initial formaldehyde concentration, C1 is the second formaldehyde concentration, and T is the first time period.

[0043] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution calculates the formaldehyde removal rate of the formaldehyde removal module in the first time period by using the initial formaldehyde concentration and the second formaldehyde concentration, so as to more accurately determine whether the formaldehyde removal module needs to be replaced, ensuring that the indoor formaldehyde concentration remains at a safe level, thereby reducing the potential threat of formaldehyde to human health.

[0044] In one embodiment of the present invention, let the historical removal rates of the formaldehyde removal module over the past n first time periods be V1, V2, V3, ... V n Based on the historical formaldehyde removal rate and efficiency of the formaldehyde removal module over the past n first time periods, it is determined whether the formaldehyde removal module meets the alarm conditions, including:

[0045] The alarm conditions must meet the following formula:

[0046] Formula 2: ;

[0047] Where n is the number of the first time intervals.

[0048] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution determines whether the formaldehyde removal module needs to be replaced by measuring its historical removal rate, accurately identifying the declining trend of the formaldehyde removal module's performance, ensuring that the formaldehyde removal module always remains in a highly efficient working state, which helps to protect indoor air quality and thus protect the health of users.

[0049] In one embodiment of the present invention, the air conditioner is equipped with a position sensor, and the control method further includes:

[0050] When the control signal includes a shutdown command, the current position of the formaldehyde removal module is obtained through the position sensor;

[0051] If the current position of the formaldehyde removal module is the second preset position, the control drive component drives the formaldehyde removal module to move from the second preset position to the first preset position, and controls the air conditioner to perform a shutdown action.

[0052] If the current position of the formaldehyde removal module is the first preset position, then control the air conditioner to perform a shutdown action.

[0053] Compared with existing technologies, the technical effects achieved by this solution are as follows: Before the air conditioner is turned off, the formaldehyde removal module is moved to a first preset position so that it is not directly exposed to the airflow at the air inlet when the air conditioner is turned on next time. This can prevent the formaldehyde removal module from being damaged due to direct airflow, thereby extending the service life of the formaldehyde removal module.

[0054] On the other hand, the present invention also provides a control device for a formaldehyde removal module. The control device is used to execute the control method as described in any of the above technical solutions. The control device includes a first control module, which is used to make the air conditioner enter a cooling mode or a heating mode according to the control signal when the control device sends a control signal to the air conditioner; a judgment module, which is used to obtain the indoor temperature before the air conditioner enters the cooling mode or the heating mode, and to determine whether the formaldehyde removal module needs to avoid the air inlet based on the indoor temperature; and a second control module, which is used to control the driving component to drive the formaldehyde removal module to move to a first preset position when the formaldehyde removal module needs to avoid the air inlet; or to control the driving component to drive the formaldehyde removal module to move to a second preset position opposite to the air inlet when the formaldehyde removal module does not need to avoid the air inlet; or to control the driving component to drive the formaldehyde removal module to move to the second preset position when the indoor temperature reaches the preset temperature of the air conditioner.

[0055] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The control device for the formaldehyde removal module provided by this solution includes the control method described in any of the above technical solutions. Therefore, this solution has all the beneficial effects described in any of the above technical solutions, which will not be repeated here.

[0056] Thirdly, the present invention also provides an air conditioner, which includes a control device as described in any of the above technical solutions, a processor, and a memory. The memory is used to store a program, and the processor is used to implement the control method as described in any of the above technical solutions when executing the program.

The memory is used to store programs, and the processor is used to implement the control method as described in any of the above technical solutions when executing the programs. Therefore, this solution has all the beneficial effects described in any of the above technical solutions, which will not be repeated here.

[0058] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0059] This invention provides a control method, control device, and air conditioner for a formaldehyde removal module. When the air conditioner receives a control signal from the control device, it determines whether the formaldehyde removal module needs to avoid the air inlet based on the indoor temperature. If so, the control drive component drives the formaldehyde removal module to avoid the air inlet. When the user urgently needs to cool down or heat up, the formaldehyde removal module can avoid the air inlet, allowing the air entering from the air inlet to directly enter the air conditioner for heat exchange, and finally be blown out from the air outlet. This increases the cross-sectional area of ​​the air inlet channel of the air conditioner, increases the air intake volume of the air conditioner, and thus improves the heat exchange efficiency of the air conditioner.

[0065] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] To solve the above-mentioned technical problems, firstly, such as Figure 1 As shown, this invention provides a control method for a formaldehyde removal module. The formaldehyde removal module is installed at a position opposite to the air inlet of an air conditioner. A drive component for controlling the rotation of the formaldehyde removal module is provided at the connection between the formaldehyde removal module and the air conditioner. The air conditioner is communicatively connected to a control device. The control method includes:

[0067] S100: When the control device sends a control signal to the air conditioner, the air conditioner enters the cooling mode or heating mode according to the control signal.

[0068] S200: Before the air conditioner enters cooling or heating mode, it obtains the indoor temperature and determines whether the formaldehyde removal module needs to avoid the air inlet based on the indoor temperature.

[0069] S210: If so, control the driving component to drive the formaldehyde removal module to move to the first preset position which is misaligned with the air inlet;

[0070] S220: If not, control the driving component to drive the formaldehyde removal module to move to the second preset position which is opposite to the air inlet, so that the formaldehyde removal module can carry out formaldehyde removal work on the indoor environment;

[0071] Among them, when the indoor temperature reaches the preset temperature of the air conditioner, control the driving component to drive the formaldehyde removal module to move to the second preset position.

[0072] Specifically, when the air conditioner receives the control signal sent by the control device, this solution determines whether the formaldehyde removal module needs to avoid the air inlet according to the indoor temperature. If so, control the driving component to drive the formaldehyde removal module to avoid the air inlet. When the user urgently needs to cool down or heat up, the formaldehyde removal module can avoid the air inlet, allowing the air entering from the air inlet to directly enter the air conditioner for heat exchange and then be blown out from the air outlet. This increases the cross-sectional area of the air inlet channel of the air conditioner, increases the air intake of the air conditioner, and thus improves the heat exchange efficiency of the air conditioner.

[0073] More specifically, when the formaldehyde removal module avoids the air inlet, this solution controls the driving component to move the formaldehyde removal module to the first preset position which is misaligned with the air inlet to reduce the obstruction of the formaldehyde removal module to the air flow, allowing more air to directly enter the air conditioner. As a result, the heat exchanger inside the air conditioner can contact more air, improving the heat exchange efficiency of the air conditioner. On the other hand, when the formaldehyde removal module does not avoid the air inlet, control the driving component to drive the formaldehyde removal module to move to the second preset position which is opposite to the air inlet, so that the formaldehyde removal module can carry out formaldehyde removal work on the indoor environment, ensuring that the indoor formaldehyde concentration remains at a safe level and guaranteeing the living safety of users.

[0074] In an embodiment provided by the present invention, before the air conditioner enters the cooling mode, the indoor temperature includes the first indoor temperature. Define the first indoor temperature as T1 and the first preset temperature of the air conditioner as Ta. Judging whether the formaldehyde removal module needs to avoid the air inlet according to the indoor parameters includes:

[0075] If T1 < Ta, it is determined that the formaldehyde removal module does not need to avoid the air inlet;

[0076] If T1 > Ta, obtain the information on the presence of people in the room and judge whether there is anyone in the room according to the information on the presence of people;

[0077] If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and control the formaldehyde removal module to avoid the air inlet.

[0078] Specifically, before the air conditioner enters the cooling mode, based on the first indoor temperature in the room and the first preset temperature of the air conditioner, the air conditioner can accurately determine whether to adjust the position of the formaldehyde removal module, so as to improve the cooling effect of the air conditioner while ensuring the indoor air quality, thereby enhancing the user experience.

[0079] Specifically, when T1 > Ta, that is, when the indoor temperature is higher than the preset temperature, if there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet and control it to avoid the air inlet to increase the air intake volume and improve the cooling efficiency of the air conditioner, so that the indoor temperature drops faster. When T1 < Ta, that is, when the indoor temperature is lower than the preset temperature, the formaldehyde removal module does not avoid the air inlet and continues the formaldehyde removal work to ensure that the indoor air quality is not affected.

[0080] In an embodiment provided by the present invention, before the air conditioner enters the heating mode, the indoor temperature includes the first indoor temperature. Define the second indoor temperature as T2 and the second preset temperature of the air conditioner as Tb. According to the indoor temperature, determining whether the formaldehyde removal module needs to avoid the air inlet further includes:

[0081] If T2 > Tb, it is determined that the formaldehyde removal module does not need to avoid the air inlet;

[0082] If T2 < Tb, obtain the presence information of people in the room, and based on the presence information of people, determine whether there is someone in the room;

[0083] If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and control the formaldehyde removal module to avoid the air inlet.

[0084] Specifically, before the air conditioner enters the heating mode, based on the second indoor temperature in the room and the second preset temperature of the air conditioner, the air conditioner can accurately determine whether to adjust the position of the formaldehyde removal module, so as to improve the heating effect of the air conditioner while ensuring the indoor air quality, thereby enhancing the user experience.

[0085] Specifically, when T2 < Tb, that is, when the indoor temperature is lower than the preset temperature, if there is no one in the room, it is determined that the formaldehyde removal module meets the avoidance condition and controls it to avoid the air inlet to increase the air intake volume and improve the heat exchange efficiency of the air conditioner, thereby accelerating the indoor heating speed. When T1 < Ta, that is, when the indoor temperature is lower than the preset temperature, the formaldehyde removal module does not avoid the air inlet and continues the formaldehyde removal work to ensure that the indoor air quality is not affected.

[0086] In an embodiment provided by the present invention, the control method further includes:

[0087] Before the air conditioner enters the cooling mode or the heating mode, obtain the current first formaldehyde concentration in the room, and define the first formaldehyde concentration as C1;

[0088] If there is someone indoors, it is determined whether the formaldehyde removal module needs to avoid the air inlet according to the magnitude relationship between C1 and Ca, and between C1 and Cb.

[0089] When C1 > Ca or Ca > C1 > Cb, it is determined that the formaldehyde removal module does not need to avoid the air inlet, and the formaldehyde removal module is controlled not to avoid the air inlet.

[0090] When C1 < Cb, it is judged whether there is a human reaction indoors. The human reaction includes frequent blinking and / or coughing.

[0091] If there is a human reaction, it is determined that the formaldehyde removal module does not need to avoid the air inlet.

[0092] If there is no human reaction, it is determined that the formaldehyde removal module needs to avoid the air inlet, and the driving component is controlled to drive the formaldehyde removal module to avoid the air inlet.

[0093] Where Ca and Cb are preset values, and Ca > Cb.

[0094] Specifically, this solution realizes the precise control of the formaldehyde removal module by intelligently judging the indoor formaldehyde concentration and the personnel status, ensuring the indoor air quality, and improving the user's comfort and safety. It should be noted that the human reaction and personnel information mentioned in this invention are detected by an infrared sensor or a first control module for human reaction.

[0095] Specifically, when C1 > Ca or Ca > C1 > Cb, it indicates that the indoor formaldehyde concentration is relatively high. At this time, it is determined that the formaldehyde removal module does not need to avoid the air inlet and continues the formaldehyde removal work to reduce the formaldehyde concentration and ensure the health of personnel. When C1 < Cb, that is, the indoor formaldehyde concentration is lower than the safety threshold. At this time, it is further judged whether there is a human reaction. If there is no human reaction, the formaldehyde removal module is controlled to avoid the air inlet to increase the air intake and improve the refrigeration efficiency.

[0096] In an embodiment provided by the present invention, the air conditioner is provided with an alarm device for emitting an alarm signal for replacing the formaldehyde removal module. The control method further includes:

[0097] Obtain the initial formaldehyde concentration indoors when the formaldehyde removal module is performing formaldehyde removal work, and obtain the second formaldehyde concentration indoors after an interval of the first time period.

[0098] According to the initial formaldehyde concentration and the second formaldehyde concentration, calculate the formaldehyde removal speed of the formaldehyde removal module within the first time period.

[0099] According to the historical formaldehyde removal speed and formaldehyde removal efficiency of the formaldehyde removal module in the past n first time periods, judge whether the formaldehyde removal module meets the alarm condition.

[0100] If the alarm condition is met, control the alarm device to emit an alarm signal.

[0101] Specifically, this solution predicts the performance degradation of the formaldehyde removal module based on its historical removal rate. This allows the air conditioner to promptly remind users to replace the module when it can no longer meet indoor formaldehyde removal needs, ensuring that indoor formaldehyde concentrations remain at safe levels, reducing the harm of formaldehyde to the human body, and protecting the safety of users. Furthermore, by calculating the formaldehyde removal rate of the module using initial and second formaldehyde concentrations, it can accurately determine whether the module needs replacement, thus improving the accuracy of the assessment of the module's performance degradation. It should be noted that the alarm device uses at least one of the following methods to issue alarm signals: voice broadcast, special sound prompts, display, and message reminders via SMS, WeChat, or email.

[0102] In one embodiment of the present invention, the formaldehyde removal efficiency is defined as V. n+1 Based on the initial formaldehyde concentration and the second formaldehyde concentration, the formaldehyde removal rate of the formaldehyde removal module during the first time period is calculated as follows:

[0103] The formula for calculating the formaldehyde removal rate of the formaldehyde removal module in the first time period is as follows:

[0104] Formula 1: ;

[0105] Where C0 is the initial formaldehyde concentration, C1 is the second formaldehyde concentration, and T is the first time period.

[0106] Specifically, this solution calculates the formaldehyde removal rate of the formaldehyde removal module within the first time period based on the initial and second formaldehyde concentrations. This allows for a more accurate determination of whether the formaldehyde removal module needs to be replaced, ensuring that the indoor formaldehyde concentration remains at a safe level and thus reducing the potential threat of formaldehyde to human health.

[0107] In one embodiment of the present invention, the historical removal rates of the formaldehyde removal module over the past n first time periods are assumed to be V1, V2, V3, ... V n Based on the historical formaldehyde removal rate and efficiency of the formaldehyde removal module over the past n first time periods, it is determined whether the formaldehyde removal module meets the alarm conditions, including:

[0108] The alarm conditions must meet the following formula:

[0109] Formula 2: ;

[0110] Where n is the number of the first time intervals.

[0111] Specifically, this solution uses the historical removal rate of the formaldehyde removal module to determine whether the module needs to be replaced, accurately identifying the declining trend in the module's formaldehyde removal performance and ensuring that the module always operates at high efficiency. This helps to protect indoor air quality and thus safeguards the user's health.

[0112] In one embodiment of the present invention, the air conditioner is equipped with a position sensor, and the control method further includes:

[0113] When the control signal includes a shutdown command, the current position of the formaldehyde removal module is obtained through the position sensor;

[0114] If the current position of the formaldehyde removal module is the second preset position, the control drive component drives the formaldehyde removal module to move from the second preset position to the first preset position, and controls the air conditioner to perform a shutdown action.

[0115] If the current position of the formaldehyde removal module is the first preset position, then control the air conditioner to perform a shutdown action.

[0116] Specifically, this solution controls the formaldehyde removal module to move to a first preset position before the air conditioner is turned off, so that the formaldehyde removal module is not directly exposed to the airflow at the air inlet when the air conditioner is turned on next time. This can avoid the formaldehyde removal module from being degraded or damaged due to direct airflow, thereby extending the service life of the formaldehyde removal module.

[0117] Secondly, such as Figure 2 As shown, the present invention also provides a control device for a formaldehyde removal module. The control device is used to execute the control method as described in any of the above technical solutions. The control device includes a first control module 100, a judgment module 200, and a second control module 300. Specifically, the first control module 100 is used to enable the air conditioner to enter a cooling mode or a heating mode according to the control signal when the control device sends a control signal to the air conditioner. The judgment module 200 is used to obtain the indoor temperature before the air conditioner enters the cooling mode or the heating mode, and to determine whether the formaldehyde removal module needs to avoid the air inlet based on the indoor temperature. The second control module 300 is used to control the driving component to drive the formaldehyde removal module to move to a first preset position when the formaldehyde removal module needs to avoid the air inlet; or to control the driving component to drive the formaldehyde removal module to move to a second preset position opposite to the air inlet when the formaldehyde removal module does not need to avoid the air inlet; or to control the driving component to drive the formaldehyde removal module to move to the second preset position when the indoor temperature reaches the preset temperature of the air conditioner.
