Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a control method and a control device for a formaldehyde removal module and an air conditioner. Background Art

[0002] With the progress of society, people's demand for health is getting higher and higher. As a necessary appliance in the home, air conditioners are gradually moving closer to health, and air conditioners with formaldehyde removal modules are becoming more and more popular among the public.

[0003] Air conditioners on the market with formaldehyde removal modules usually install the module on the air inlet side of the air conditioner and set it opposite to the air inlet to ensure that before the air enters the air conditioner for circulation, the formaldehyde removal module can first filter and purify harmful substances such as formaldehyde in the air, thereby improving the formaldehyde removal effect of the formaldehyde removal module.

[0004] However, there is at least one of the following problems in the related technology: in the prior art, the formaldehyde removal module of the air conditioner is usually fixedly installed in a position relative to the air inlet. When the air conditioner is started (such as cooling or heating mode), the airflow must first flow through the formaldehyde removal module and then enter the air conditioner for heat exchange, which reduces the cross-sectional area of ​​the air inlet channel and causes a decrease in the air intake volume. When the user urgently needs to cool down or heat up, insufficient air intake will prolong the temperature adjustment time, affecting the heat exchange efficiency of the air conditioner, thereby affecting the user experience. Summary of the invention

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

[0006] In order to solve the above technical problems, the present invention provides a control method for a formaldehyde removal module, wherein the formaldehyde removal module is installed at a position opposite to the air inlet of the air conditioner, and a driving component for controlling the rotation of the formaldehyde removal module is provided at the connection between the formaldehyde removal module and the air conditioner, and the air conditioner is communicatively connected with the control device, and the control method comprises: When the 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 cooling mode or heating mode, the indoor temperature is obtained, and according to the indoor temperature, it is determined whether the formaldehyde removal module needs to avoid the air inlet; If yes, the driving component is controlled to drive the formaldehyde removal module to move to a first preset position that is offset from the air inlet; If not, control the driving component to drive the formaldehyde removal module to move to a second preset position opposite to the air inlet, so that the formaldehyde removal module performs formaldehyde removal work on the indoor environment; 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.

[0007] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: When the air conditioner receives a 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 finally 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.

[0008] 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 a first preset position offset from 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 come into contact with 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 a second preset position opposite to the air inlet, so that the formaldehyde removal module performs 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.

[0009] In an example of the present invention, before the air conditioner enters the cooling mode, the indoor temperature includes a 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: If T1 < Ta, it is determined that the formaldehyde removal module does not need to avoid the air inlet; 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; 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.

[0010] 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 judge 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.

[0011] In an example of the present invention, before the air conditioner enters the heating mode, the indoor temperature includes a first indoor temperature. Define the second indoor temperature as T2, and define the second preset temperature of the air conditioner as Tb. According to the indoor parameters, it is determined whether the formaldehyde removal module needs to avoid the air inlet, and it further includes: If T2>Tb, it is determined that the formaldehyde removal module does not need to avoid the air inlet; If T2<Tb, the presence information of people in the room is obtained, and based on the presence information of people, it is determined whether there are people in the room; If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and the formaldehyde removal module is controlled to avoid the air inlet.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution: 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.

[0013] In an example of the present invention, the control method further includes: Before the air conditioner enters the cooling mode or the heating mode, the first formaldehyde concentration in the current room is obtained, and the first formaldehyde concentration is defined as C1; If there are people in the room, according to the magnitude relationship between C1 and Ca, and C1 and Cb, it is determined whether the formaldehyde removal module needs to avoid the air inlet; 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; When C1<Cb, it is determined whether the people in the room have a human reaction, and the human reaction includes frequent blinking and / or coughing; If a human reaction occurs, it is determined that the formaldehyde removal module does not need to avoid the air inlet; If no human reaction occurs, 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; Wherein, Ca and Cb are preset values, and Ca>Cb.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution: This solution realizes the precise control of the formaldehyde removal module by intelligently judging the indoor formaldehyde concentration and the personnel status, ensures the indoor air quality, and improves the comfort and safety of users.

[0015] In an example of the present invention, the air conditioner is provided with an alarm device for emitting an alarm signal for replacing the formaldehyde removal module. When the indoor temperature reaches the preset temperature of the air conditioner, the control method further includes: Acquire the initial formaldehyde concentration in the room when the formaldehyde removal module performs formaldehyde removal work, and acquire the second formaldehyde concentration in the room after a first time period; Calculating the formaldehyde removal rate of the formaldehyde removal module in the first time period according to the initial formaldehyde concentration and the second formaldehyde concentration; Determine whether the formaldehyde removal module meets the alarm condition according to the historical formaldehyde removal speed and the formaldehyde removal speed of the formaldehyde removal module in the past n first time periods; If the alarm conditions are met, the alarm device is controlled to send out an alarm signal.

[0016] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: This solution predicts the performance degradation of the formaldehyde removal module according to the historical removal speed of the formaldehyde removal module, so that the air conditioner can promptly remind the user to replace the formaldehyde removal module when the formaldehyde removal module cannot meet the indoor formaldehyde removal demand, ensure that the indoor formaldehyde concentration is continuously at a safe level, reduce the harm of formaldehyde to the human body, and ensure the user's living safety. Furthermore, by calculating the formaldehyde removal speed of the formaldehyde removal module through the initial formaldehyde concentration and the second formaldehyde concentration, it is possible to accurately judge whether the formaldehyde removal module needs to be replaced, thereby improving the accuracy of the judgment result on the performance degradation of the formaldehyde removal module.

[0017] In one embodiment of the present invention, the formaldehyde removal rate is defined as V n+1 , according to the initial formaldehyde concentration and the second formaldehyde concentration, calculating the formaldehyde removal rate of the formaldehyde removal module in the first time period includes: The calculation formula for calculating the formaldehyde removal rate of the formaldehyde removal module in the first time period is: Formula 1: ; Among them, C 0 is the initial formaldehyde concentration, C1 is the second formaldehyde concentration, and T is the first time period.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical scheme is: this scheme calculates the formaldehyde removal rate of the formaldehyde removal module in the first time period through the initial formaldehyde concentration and the second formaldehyde concentration, so as to more accurately judge 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.

[0019] In one example of the present invention, the historical removal rates of the aldehyde removal module in the past n first time periods are V 1 、V 2 、V 3 ,…V n , judging whether the formaldehyde removal module meets the alarm condition according to the historical formaldehyde removal speed and the formaldehyde removal speed of the formaldehyde removal module in the past n first time periods, including: The alarm condition must satisfy the following formula: Formula 2: ; Wherein, n is the number of the first time intervals.

[0020] Compared with the existing technology, the technical effect achieved by adopting this technical scheme is: this scheme judges whether the formaldehyde removal module needs to be replaced by the historical removal rate of the formaldehyde removal module, so as to accurately identify the downward trend of the formaldehyde removal performance of the formaldehyde removal module, ensure that the formaldehyde removal module always remains in an efficient working state, help to ensure indoor air quality, and thus protect the health of users.

[0021] In one embodiment of the present invention, the air conditioner is provided with a position sensor, and the control method further comprises: When the control signal includes a shutdown instruction, the current position of the formaldehyde removal module is obtained through a position sensor; If the current position of the formaldehyde removal module is the second preset position, the driving component is controlled to drive the formaldehyde removal module to move from the second preset position to the first preset position, and the air conditioner is controlled to perform a shutdown action; If the current position of the formaldehyde removal module is the first preset position, the air conditioner is controlled to execute a shutdown action.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical scheme is as follows: this scheme controls the formaldehyde removal module to move to the first preset position before the air conditioner is shut down, so as to place the formaldehyde removal module directly exposed to the airflow at the air inlet when the air conditioner is started next time.

[0031] In order to solve the above technical problems, firstly, Figure 1 As shown, 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 the air conditioner, a driving 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 connected to the control device for communication, and the control method includes: S100: When the 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; S200: before the air conditioner enters the cooling mode or the heating mode, obtaining the indoor temperature, and judging whether the formaldehyde removal module needs to avoid the air inlet according to the indoor temperature; S210: If yes, control the driving component to drive the formaldehyde removal module to move to a first preset position that is offset from the air inlet; S220: If not, the driving component is controlled to drive the formaldehyde removal module to move to a second preset position arranged opposite to the air inlet, so that the formaldehyde removal module removes formaldehyde from the room; When the indoor temperature reaches the preset temperature of the air conditioner, the control driving component drives the formaldehyde removal module to move to the second preset position.

[0032] Specifically, this solution determines whether the formaldehyde removal module needs to avoid the air inlet based on the indoor temperature when the air conditioner receives a control signal sent by the control device. If so, the drive component is controlled 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, so that the air entering from the air inlet directly enters the air conditioner for heat exchange, and is finally blown out from the air outlet, thereby increasing the cross-sectional area of ​​the air inlet channel of the air conditioner, increasing the air intake volume of the air conditioner, and thus improving the heat exchange efficiency of the air conditioner.

[0033] More specifically, this solution controls the driving component to move the formaldehyde removal module to a first preset position offset from the air inlet when the formaldehyde removal module avoids the air inlet, so as to reduce the obstruction of the formaldehyde removal module to the airflow, allowing more air to directly enter the air conditioner, so that the heat exchanger inside the air conditioner can be exposed to more air, thereby improving the heat exchange efficiency of the air conditioner. On the other hand, when the formaldehyde removal module does not avoid the air inlet, the driving component is controlled to drive the formaldehyde removal module to move to a second preset position opposite to the air inlet, so that the formaldehyde removal module removes formaldehyde from the room, ensuring that the indoor formaldehyde concentration is continuously at a safe level, thereby ensuring the user's living safety.

[0034] In an embodiment provided by the present invention, before the air conditioner enters the cooling mode, the indoor temperature includes a first indoor temperature, the first indoor temperature is defined as T1, the first preset temperature of the air conditioner is defined as Ta, and according to the indoor parameters, it is judged whether the formaldehyde removal module needs to avoid the air inlet, including: If T1 < Ta, it is determined that the formaldehyde removal module does not need to avoid the air inlet; If T1 > Ta, the presence information of people in the room is obtained, and according to the presence information of people, it is judged whether there is anyone in the room; If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and the formaldehyde removal module is controlled to avoid the air inlet.

[0035] Specifically, in this solution, before the air conditioner enters the cooling mode, through the first indoor temperature in the room and the first preset temperature of the air conditioner, the air conditioner can accurately judge 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.

[0036] 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, improve the cooling efficiency of the air conditioner, and make the indoor temperature drop 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.

[0037] In an embodiment provided by the present invention, before the air conditioner enters the heating mode, the indoor temperature includes a first indoor temperature, the second indoor temperature is defined as T2, the second preset temperature of the air conditioner is defined as Tb, and according to the indoor parameters, it is judged whether the formaldehyde removal module needs to avoid the air inlet, further including: If T2 > Tb, it is determined that the formaldehyde removal module does not need to avoid the air inlet; If T2 < Tb, the presence information of people in the room is obtained, and according to the presence information of people, it is judged whether there is anyone in the room; If there is no one in the room, it is determined that the formaldehyde removal module needs to avoid the air inlet, and the formaldehyde removal module is controlled to avoid the air inlet.

[0038] Specifically, in this solution, before the air conditioner enters the heating mode, through the second indoor temperature in the room and the second preset temperature of the air conditioner, the air conditioner can accurately judge 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.

[0039] 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 its air inlet is controlled to avoid, so as to increase the air intake and improve the heat exchange efficiency of the air conditioner, thereby accelerating the indoor temperature rise 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.

[0040] In an embodiment provided by the present invention, the control method further includes: Before the air conditioner enters the cooling mode or the heating mode, obtain the first formaldehyde concentration in the room currently, and define the first formaldehyde concentration as C1; If there is someone in the room, judge 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; 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; When C1 < Cb, judge whether there is a human reaction in the room, and the human reaction includes frequent blinking and / or coughing; If there is a human reaction, it is determined that the formaldehyde removal module does not need to avoid the air inlet; 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; Wherein, Ca and Cb are preset values, and Ca > Cb.

It should be noted that the human reaction and personnel information mentioned in the present invention are detected by an infrared sensor or a first control module for human reaction.

[0042] 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, increase the air intake, and improve the cooling efficiency.
