[0036] The control method for removing formaldehyde provided by the present disclosure obtains the current formaldehyde concentration and the current indoor temperature in the room when it is determined that the user is away from home. According to the current formaldehyde concentration, the current indoor temperature and the target formaldehyde concentration to be achieved in the room, the operating parameters for removing formaldehyde are determined. The air conditioner is controlled to operate according to the operating parameters to achieve the indoor formaldehyde removal operation after the user leaves home.

[0037] Through the formaldehyde removal control method provided by the present invention, the time when the user is away from home can be effectively utilized to achieve indoor formaldehyde removal operations, improve the efficiency of formaldehyde removal, avoid discomfort to the human body, and enhance the user experience.

[0038] Optionally, the step of determining the operating parameters of the air conditioner to remove formaldehyde according to the current formaldehyde concentration C1, the current indoor temperature and the target formaldehyde concentration includes: determining the temperature adjustment time t according to the current indoor temperature and the target temperature. s and the additional formaldehyde concentration C released during the temperature adjustment period S . According to the current formaldehyde concentration C1, the new formaldehyde concentration C S And the target formaldehyde concentration C0, determine the operating parameters of the air conditioner to remove formaldehyde.

[0039] In this embodiment, the temperature adjustment mode of the air conditioner is controlled by the current indoor temperature and the target temperature to determine the temperature adjustment time required to adjust the current indoor temperature to the target temperature. And the new formaldehyde concentration released indoors during the temperature adjustment operation mode. According to the current formaldehyde concentration in the room, the new formaldehyde concentration and the target formaldehyde concentration to be achieved indoors, the operating parameters of the air conditioner for formaldehyde removal during the time period when the user is away from home are determined to improve the efficiency of indoor formaldehyde removal, and make full use of the time period when the user is away from home, which can not only improve the effect of formaldehyde removal, but also improve the comfort of the user.

[0040] In some embodiments, in combination Figure 2 As shown, a control method for removing formaldehyde is provided, and the control method comprises:

[0041] S202, when the user is away from home, obtain the current formaldehyde concentration C1 and the current indoor temperature in the room.

[0042] S204, determining the temperature adjustment time t according to the current indoor temperature and the target temperature s and the additional formaldehyde concentration C released during the temperature adjustment period S .

[0043] S206, determining the time t for the user to return home z .

[0044] S208, according to C1 and C S , determine t z The predicted formaldehyde concentration in the room after the end y .

[0045] S210, in C y ≥C0, make sure the air conditioner operates in formaldehyde removal mode.

[0046] S212, in C y When the temperature is lower than C0, make sure the air conditioner runs in temperature control mode first and then in formaldehyde removal mode.

[0047] S214, controlling the operation of the air conditioner according to the operating parameters.

[0048] In this embodiment, when it is determined that the user is away from home, the current formaldehyde concentration C1 and the current indoor temperature are obtained, and the time t when the user returns home is determined. z . According to the current indoor temperature and the target temperature, determine the temperature adjustment time required to adjust the current indoor temperature to the target temperature. And the newly released formaldehyde concentration in the room during the temperature adjustment time. Determine the time it takes for the user to go home and use it as the total operation time of the formaldehyde removal operation. According to the current formaldehyde concentration in the room and the newly added formaldehyde concentration during the temperature adjustment operation, combined with the temperature adjustment time, determine the predicted formaldehyde concentration in the room after the temperature adjustment time ends. Compare the predicted formaldehyde concentration with the target formaldehyde concentration. Based on the comparison results, determine the formaldehyde removal operation parameters that match the temperature adjustment time.

[0049] Specifically, in C y ≥C0, it means that after running the temperature adjustment mode first and then the formaldehyde removal mode, the indoor formaldehyde concentration is higher than the target formaldehyde concentration. That is, it is not allowed to adjust the temperature to the target temperature and then run the formaldehyde removal mode within the time when the user returns home. In this way, the air conditioner is determined to run the formaldehyde removal mode, that is, the air conditioner is controlled to run only the air supply mode, and the compressor is controlled to be in the off state.

[0050] In C y When the temperature is less than C0, it means that within the time until the user returns home, the temperature adjustment mode can be allowed to adjust the indoor ambient temperature to the target temperature to increase the formaldehyde release rate and improve the formaldehyde removal effect. After the temperature adjustment is completed, the formaldehyde removal mode is allowed to remove formaldehyde from the room.

[0051] Optionally, the air conditioner includes a camera device or a human body detection device, which detects whether there is anyone in the room through the camera device or the human body detection device. In the case of no one, it is determined that the user is away from home. In order to improve the accuracy of the user leaving home detection, a human body detection cycle is set to periodically detect human body information in the room. The value range of the human body detection cycle is 5 minutes to 10 minutes.

[0052] Optionally, the temperature adjustment mode includes a cooling mode or a heating mode to adjust the indoor ambient temperature to a target temperature, so as to increase the formaldehyde release rate by increasing the indoor ambient temperature.

The preset formula is: C y =C1+C S -v2×(t z -t s ) where v2 is the rate of decrease of formaldehyde concentration in the formaldehyde removal mode of the air conditioner, t s The thermostat time for thermostat mode operation.

[0055] In this embodiment, the expected formaldehyde concentration in the room at the end of the return time is calculated according to a preset formula. Then, it can be determined whether the indoor formaldehyde concentration can be reduced to or below the target formaldehyde concentration after running in the preset mode. If it can be reached, the preset mode is run. If it cannot be reached, the temperature adjustment mode is not performed, and the formaldehyde removal mode is directly run.

[0056] Among them, the preset mode includes running the temperature adjustment mode first and then running the formaldehyde removal mode.

[0057] Optionally, in C y When the formaldehyde concentration is less than C0, the current formaldehyde concentration C1 and the newly added formaldehyde concentration C S and the target formaldehyde concentration C0, and the step of determining the operating parameters of the air conditioner to remove formaldehyde also includes: according to the formula: C1+C S +v1×t1-v2×(t z -t s-t1)=C0, calculate the continuous operation time t1 of controlling the air conditioner to maintain the target temperature. t1=(C0-C1-C S -v2×t z +v2×t s ) / (v1+v2).

[0058] In this embodiment, at C y When the indoor temperature is less than C0, the continuous operation time of controlling the air conditioner to maintain the target temperature is further determined after the indoor temperature reaches the target temperature. And the air conditioner operation is controlled according to the determined continuous operation time. Among them, according to the indoor formaldehyde concentration C1 when the user leaves home and the newly added formaldehyde concentration during the operation of the temperature adjustment mode, and the formaldehyde release during the continuous operation time to maintain the target temperature. Combined with the formaldehyde reduction amount and the indoor target formaldehyde concentration C0 in the formaldehyde removal mode. Calculate the continuous operation time t1 for controlling the air conditioner to keep the indoor temperature at the target temperature.

[0059] By controlling the air conditioner to maintain the indoor temperature at the target temperature, the indoor ambient temperature can be increased, thereby increasing the formaldehyde release rate and improving the formaldehyde removal efficiency and effect.

[0063] In this embodiment, after determining that the user is away from home, the user's location information is periodically obtained to determine whether the user is returning home based on changes in the user's location information. If the user is returning home, determine the user's homecoming time t z . To adjust the operating parameters of the air conditioner according to the time it takes to go home, so as to improve the efficiency and effect of removing formaldehyde. Among them, the time it takes to go home in this embodiment refers to the interval between the time when the user is confirmed to be in the state of going home and the time when the user returns home.

[0064] Optionally, the period for obtaining the user's location information includes but is not limited to: 30 minutes, 2 hours or 3 hours.

[0065] Optionally, when the user is in the state of returning home, the distance between the user's location information and the address information of the air conditioner is determined. When the distance is less than or equal to the preset distance, the time to return home is determined according to the distance and the user's preset transportation method, and the operating parameters of the air conditioner are adjusted. The preset transportation method can be customized by the user.

[0066] Furthermore, when the distance is less than or equal to the preset distance, the current formaldehyde concentration C in the room is obtained again. d1 , calculate the indoor formaldehyde concentration C when the user returns home in the case of continuous operation of formaldehyde removal mode h =v2×t s . h and the current formaldehyde concentration C obtained again d1 For comparison. h ≤C d1 In the case of a temperature drop, it indicates that the heating mode needs to be switched to the cooling mode immediately, and the indoor ambient temperature is adjusted to the target comfort temperature, which ranges from 18°C ​​to 21°C, to improve the user's comfort after returning home. In addition, the air conditioner is controlled to operate in the formaldehyde removal mode. When it is detected that the user has returned home, the indoor formaldehyde concentration is obtained again. When the formaldehyde concentration is greater than the target formaldehyde concentration, a prompt message is issued to remind the user that the formaldehyde exceeds the standard and take measures.

[0067] In C h >C d1 In the case of , the air conditioner is controlled to continue heating operation, and the continuous operation time is t2 = (v2×t s -C d1 ) / (v1+v2), and then control the air conditioner to run in formaldehyde removal mode.

[0068] When the distance is greater than the preset distance, the operating parameters of the air conditioner will not be adjusted, and the air conditioner will continue to operate according to the operating parameters determined by the time it takes the user to return home when the user is away from home.

[0069] Optionally, the preset distance is 2 / 3 to 3 / 4 of the maximum value of the distance from the location information of the user after leaving home to the address information of the air conditioner. For example, if the distance from the user's workplace to the home address is L, the preset distance is L×2 / 3.

[0070] Optionally, the air conditioner is connected to communicate with a mobile phone or wearable device of the user to obtain the user's location information through the mobile phone or wearable device.

[0071] Optionally, the step of determining whether the user is in the home state according to the user's location information includes: determining the distance between the user's location information and the address information of the air conditioner. The multiple distances obtained periodically gradually decrease, and it is determined that the user is in the home state. The multiple distances obtained periodically gradually increase, and it is determined that the user is away from home.

[0072] In this embodiment, the distance between the user's location information and the address information of the air conditioner is calculated. Multiple distances obtained periodically are compared. If the multiple distances show a trend of gradually decreasing, it is determined that the user is in the state of returning home. Then, based on the user's location information, the time required for the user to return home is determined. If the multiple distances show a trend of gradually increasing, it is determined that the user is away from home. Through the user's location information, it is determined whether the user is in the state of returning home or away from home, so as to adjust the operating parameters of the air conditioner, so as to provide a relatively comfortable indoor environment after the user returns home and improve the user's experience while achieving indoor formaldehyde removal.
