[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 in the case that the user is in a state of leaving home. The operation parameter for removing formaldehyde is determined according to the current formaldehyde concentration, the current indoor temperature and the target formaldehyde concentration to be reached in the room. The air conditioner is controlled to operate according to the operation parameter, so as to realize the operation of removing formaldehyde in the room after the user leaves home.

[0037] The control method for removing formaldehyde provided by the present disclosure can effectively utilize the period when the user leaves home, realize the operation of removing formaldehyde in the room, improve the efficiency of removing formaldehyde, and avoid discomfort to the human body, thereby improving the user experience.

[0038] Optionally, the step of determining the operation parameter of the air conditioner for removing formaldehyde according to the current formaldehyde concentration C1, the current indoor temperature and the target formaldehyde concentration includes: determining a temperature adjustment duration t according to the current indoor temperature and the target temperature, and determining a new formaldehyde concentration C released in the temperature adjustment duration. s According to the current formaldehyde concentration C1, the new formaldehyde concentration C and the target formaldehyde concentration C0, the operation parameter of the air conditioner for removing formaldehyde is determined. S S

[0039] In this embodiment, the temperature adjustment duration required for adjusting the current indoor temperature to the target temperature is determined by the current indoor temperature and the target temperature, and the new formaldehyde concentration released in the room 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 reached in the room, the operation parameter of the air conditioner for removing formaldehyde in the period when the user leaves home is determined, so as to improve the efficiency of removing formaldehyde in the room, and the period when the user leaves home can be fully utilized, which can improve the effect of removing formaldehyde and the comfort of the user.

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

[0041] S202, in the case that the user is in a state of leaving home, obtaining a current formaldehyde concentration C1 and a current indoor temperature in the room.

[0042] ​​S204, determining a temperature adjustment duration t based on the current indoor temperature and the target temperature s and the newly added formaldehyde concentration C released within the temperature adjustment duration S .

[0044] S208, determining t based on C1 and C S , the predicted formaldehyde concentration C in the indoor environment after the temperature adjustment duration t ends z . y .

[0045] S210, in the case of C y ≥ C0, determining that the air conditioner runs the formaldehyde removal mode.

[0046] S212, in the case of C y < C0, determining that the air conditioner runs the temperature adjustment mode first and then runs the formaldehyde removal mode.

[0047] S214, controlling the air conditioner to run based on the operation parameters

[0048] In this embodiment, in the case of determining that the user is in the away-from-home state, the current formaldehyde concentration C1 and the current indoor temperature in the indoor environment are obtained, and the home-coming duration t of the user is determined z . Based on the current indoor temperature and the target temperature, the temperature adjustment duration required for adjusting the current indoor temperature to the target temperature is determined. In addition, the newly added formaldehyde concentration released in the indoor environment within the temperature adjustment duration is determined. By determining the home-coming duration required for the user to come home, the total operation duration of the formaldehyde removal operation is determined. Based on the current formaldehyde concentration in the indoor environment and the newly added formaldehyde concentration during the temperature adjustment operation, in combination with the temperature adjustment duration, the predicted formaldehyde concentration in the indoor environment after the temperature adjustment duration ends is determined. The predicted formaldehyde concentration is compared with the target formaldehyde concentration. Based on the comparison result, the operation parameters of the formaldehyde removal operation matched with the temperature adjustment duration are determined.

[0049] Specifically, in the case of C y ≥ C0, it is indicated that the formaldehyde concentration in the indoor environment is higher than the target formaldehyde concentration after running the temperature adjustment mode first and then running the formaldehyde removal mode. That is, the temperature is not allowed to be adjusted to the target temperature within the home-coming duration of the user, and then the formaldehyde removal mode is performed. In this way, it is determined that the air conditioner runs 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 closed state.

[0050] In the case of C y < C0, it is indicated that the temperature adjustment mode can be allowed within the home-coming duration of the user to adjust the indoor environment temperature to the target temperature, so as 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 the formaldehyde in the indoor environment.

[0051] Optionally, the air conditioner comprises a camera or a human body detection device, and whether there is a human in the room is detected through the camera or the human body detection device. In the case that there is no human, it is determined that the user is in a state of leaving home. In order to improve the accuracy of the detection of the user leaving home, a human body detection period is set, and the human body information in the room is detected periodically. The value range of the human body detection period is 5 minutes to 10 minutes.

[0052] Optionally, the temperature adjustment mode comprises a cooling mode or a heating mode, so as to adjust the indoor environment temperature to a target temperature, so as to improve the release rate of formaldehyde by increasing the indoor environment temperature. The formaldehyde removal mode comprises only controlling the indoor fan to operate, so as to realize continuous circulation of indoor air, and the formaldehyde removal treatment is performed through the formaldehyde removal mechanism of the air conditioner, and the compressor is controlled to be in a closed state.

[0053] Optionally, the value range of the target temperature is 24℃ to 26℃, and the specific values include but are not limited to 24℃, 25℃ and 26℃.

[0054] Optionally, according to C1 and C S , it is determined that t z is ended, and the step of calculating the predicted formaldehyde concentration C y in the room after t y includes: calculating a preset formaldehyde concentration according to a preset formula. The preset formula is: C S =C1+C z +v1×t1-v2×(t s -t s ) wherein, v2 is the decrease rate of the formaldehyde concentration when the air conditioner operates in the formaldehyde removal mode, and t y is the temperature adjustment time length when the temperature adjustment mode operates.

[0055] In this embodiment, the concentration value of the formaldehyde concentration in the room when the home return time length is ended is calculated according to the preset formula. Then, whether the formaldehyde concentration in the room after the preset mode operates can be reduced to the target formaldehyde concentration or below can be determined. If it can be achieved, the preset mode is operated. If it cannot be achieved, the temperature adjustment mode is not operated, and the formaldehyde removal mode is directly operated.

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

[0057] Optionally, in the case that C y is less than C0, according to the current formaldehyde concentration C1, the new formaldehyde concentration C S and the target formaldehyde concentration C0, the step of determining the operation parameters of the air conditioner formaldehyde removal further comprises: according to the formula: C1+C S +v1×t1-v2×(t z -t st1) = C0, calculate the continuous operating time t1 for the air conditioner to maintain the target temperature. t1 = (C0 - C1 - C0) S -v2×t z +v2×t s ) / (v1+v2).

[0058] In this embodiment, in C y If C0 < C0, further determine the duration for which the air conditioner will maintain the target temperature after the indoor temperature reaches it. Control the air conditioner's operation based on this determined duration. Specifically, this involves considering the indoor formaldehyde concentration C1 when the user leaves, the increase in formaldehyde concentration during the temperature control mode operation, and the formaldehyde release during the duration of maintaining the target temperature. Combined with the decrease in formaldehyde concentration during formaldehyde removal mode and the target indoor formaldehyde concentration C0, calculate the duration t1 for maintaining the indoor temperature at the target temperature.

[0059] By controlling the air conditioner to maintain the indoor temperature at the target temperature, the release rate of formaldehyde is increased by raising the indoor ambient temperature, thereby improving the efficiency and effectiveness of formaldehyde removal.

[0060] In some embodiments, the time t spent at home z This refers to the time interval between when the user is determined to be away from home and when the user returns home.

[0061] Optionally, when a user is away from home, the steps for obtaining the user's return time include: obtaining the user's input return time via an input device. This allows the user to set their return time based on their work hours.

[0062] In some embodiments, the user's home time t is determined. z The steps include: periodically acquiring the user's location information; determining whether the user is at home based on the location information; and determining the duration t of the user's journey home if the user is at home. z .

[0063] In this embodiment, after determining that the user is away from home, the user's location information is periodically acquired to determine whether the user is returning home based on changes in the user's location information. If the user is returning home, the duration t of the user's journey home is determined. z This allows for adjustments to the air conditioner's operating parameters based on the duration of time the user is home, thereby improving the efficiency and effectiveness of formaldehyde removal. In this embodiment, the duration of time spent home refers to the time interval between confirming the user's arrival home and the moment the user actually arrives.

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

[0065] Optionally, when the user is in a homecoming state, the distance between the user's location information and the address information of the air conditioner is determined. If the distance is less than or equal to a preset distance, the homecoming time is determined based on the distance and the user's preset mode of transportation, and the air conditioner's operating parameters are adjusted accordingly. The preset mode of transportation can be customized by the user.

[0066] Furthermore, when the distance is less than or equal to a preset distance, the current indoor formaldehyde concentration C is obtained again. d1 The calculation shows that, under continuous formaldehyde removal mode, the indoor formaldehyde concentration C when the user returns home is [value missing]. h =v2×t s C h Compared with the current formaldehyde concentration C obtained again d1 Comparison. In C h ≤C d1 In this situation, it indicates that the heating mode needs to be switched to cooling mode immediately, adjusting the indoor temperature to the target comfort temperature, which ranges from 18℃ to 21℃, to improve the user's comfort upon arrival home. Additionally, the air conditioner will be switched to formaldehyde removal mode. Upon detecting the user's return home, the indoor formaldehyde concentration will be measured again. If the formaldehyde concentration exceeds the target concentration, a warning message will be issued to remind the user that formaldehyde levels are too high and to take appropriate measures.

[0067] In C h >C d1 Under these circumstances, the air conditioner is controlled to continue heating operation for a duration t2 = (v2 × t) s -C d1 ) / (v1+v2), and then control the air conditioner to run in formaldehyde removal mode.

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

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

[0070] Optionally, the air conditioner can communicate with the user's mobile phone or wearable device 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-returning state according to the location information of the user comprises: determining the distance between the location information of the user and the address information of the air conditioner. When the plurality of distances periodically obtained gradually decrease, it is determined that the user is in the home-returning state. When the plurality of distances periodically obtained gradually increase, it is determined that the user is in the home-leaving state.

[0072] In this embodiment, the distance between the location information of the user and the address information of the location where the air conditioner is located is calculated. The plurality of distances periodically obtained are compared. When the plurality of distances gradually decrease, it is determined that the user is in the home-returning state. Then, the home-returning time length required by the user to return home is determined according to the location information of the user. When the plurality of distances gradually increase, it is determined that the user is in the home-leaving state. By determining whether the user is in the home-returning state or the home-leaving state according to the location information of the user, the running parameters of the air conditioner are adjusted to provide a relatively comfortable indoor environment for the user after the user returns home in the case of removing formaldehyde in the indoor environment, thereby improving the use experience of the user.

[0073] Optionally, the air conditioner is provided with a positioning device. After the air conditioner is installed, the address information of the air conditioner is determined by the positioning device. In addition, the processor stores a database of the temperature adjusting time length required by different indoor temperatures to rise or fall to the target temperature and the newly added formaldehyde concentration in the temperature adjusting process. By setting the corresponding relationship database of the indoor temperature, the temperature adjusting time length and the newly added formaldehyde concentration, the temperature adjusting time length and the newly added formaldehyde concentration can be determined according to the corresponding relationship database for different indoor temperatures in the actual use process. In this way, the control precision and efficiency of removing formaldehyde can be improved.

[0074] In addition, the processor is preset with the formaldehyde release rate corresponding to the target temperature and the formaldehyde concentration decline rate in the case that the air conditioner runs in the formaldehyde removal mode.
