step S102: when the air conditioner is stopped when the heating reaches the temperature, the current initial indoor temperature and the initial outdoor temperature are detected.
In the heating process, if the air conditioner detects that the indoor environment temperature is greater than the set temperature of the user, the air conditioner can automatically stop heating so as to enable the indoor environment temperature to be close to the set temperature of the user. When the air conditioner is heated to a temperature and stops, the indoor environment temperature and the outdoor environment temperature when the air conditioner stops at the temperature are respectively detected based on the temperature sensors and are respectively recorded as an initial indoor temperature and an initial outdoor temperature.
Step S104: the current indoor ambient temperature is periodically detected, and the attenuated inner ring temperature is calculated based on the current indoor ambient temperature, the initial indoor temperature and the initial outdoor temperature.
When the air conditioner is stopped when the temperature reaches the set temperature, the indoor environment temperature is in a decay trend and gradually decreases, the current indoor environment temperature is detected once every preset time (the value range can be 1-3 min, and the optimal value is 1min), and the decayed inner ring temperature corresponding to the current period is calculated based on the detected indoor environment temperature each time and the initial indoor temperature and the initial outdoor temperature.
Step S106: and judging whether the air conditioner meets the heating recovery condition or not based on the current indoor environment temperature and the attenuated inner ring temperature, and if so, controlling the air conditioner to recover the heating operation.
In order to avoid that the detected current indoor environment temperature has a large difference with the lower layer cold air temperature sensed by a user when the indoor cold air and the indoor cold air are layered, whether the current indoor environment temperature meets the heating recovery condition or not is comprehensively judged according to the current indoor environment temperature and the inner ring temperature after attenuation obtained by theoretical calculation, and if the current indoor environment temperature meets the heating recovery condition, the air conditioner is controlled to recover the heating operation.
In a possible implementation manner, an average temperature value of the current indoor environment temperature and the attenuated inner ring temperature obtained in the current period may be calculated, and when the average temperature value is smaller than a preset recovery temperature, it is determined that the air conditioner satisfies the recovery heating condition.
In another possible implementation manner, a minimum temperature value is obtained from the current indoor environment temperature obtained in the current period and the attenuated inner ring temperature; and when the minimum temperature value is less than the preset recovery temperature, determining that the air conditioner meets the recovery heating condition. That is, as long as any one of the current indoor ambient temperature and the attenuated inner ring temperature is less than the preset recovery temperature, the air conditioner can be controlled to recover the heating operation.
The lower value of the current indoor environment temperature and the inner ring temperature after attenuation is taken as the judgment temperature for recovering heating, if the current indoor environment temperature or the inner ring temperature after attenuation is reduced to the preset recovery temperature, the air conditioner is controlled to recover heating, so that the recovery heating efficiency after heating shutdown is improved, the human comfort is prevented from being influenced, and the user experience is improved.

The initial temperature difference is calculated based on the calculation formula, the calculated initial temperature difference is related to the user set temperature, the initial indoor temperature and the initial outdoor temperature, the attenuation influence of the outdoor environment temperature on the current initial indoor temperature is comprehensively considered, and the rationality of the heating temperature-reaching shutdown control is improved.
Step (2): and calculating the average attenuation temperature difference of the current period based on the initial temperature difference and the current indoor environment temperature, and determining the accumulated temperature drop based on the initial temperature difference and the average attenuation temperature difference of each period.

ΔTi＝ΔT0*(TNRi-TNRrecovery)/(TNR0-TNRRecovery)
Wherein, TNRiCurrent detected for current period iIndoor ambient temperature, TNRRecoveryFor a preset recovery temperature, TNR0Is the initial room temperature.
The calculation formula of the accumulated temperature drop is as follows:
ΔT＝ΔT0+ΔT1+ΔT2+……+ΔTi
ΔT0is the initial temperature difference, Δ TiIs the average decay temperature difference corresponding to the current period i. The initial temperature difference is a negative value, and the average attenuation temperature difference and the accumulated temperature difference which are calculated based on the initial temperature difference are both negative values.
Considering that the indoor environment temperature is in a descending trend in a period, the average attenuation temperature difference of the indoor environment temperature in the period is approximately in an inverse proportion relation with the current indoor environment temperature detected in the initial period of the period, the average attenuation temperature difference of the indoor environment temperature in the period can be calculated by inputting the current indoor environment temperature detected in the current period into the calculation formula, the actual condition of the indoor environment temperature change is met, and an accurate basis is provided for calculating the attenuated inner ring temperature.

Wherein, TNRComputingFor damped inner ring temperature, TNR0The initial indoor temperature is calculated, the inner ring temperature after the initial indoor temperature gradually attenuates along with the increase of time can be calculated by calculating the sum of the initial indoor temperature and the accumulated temperature drop, the problem of difficulty in heating recovery after the heating shutdown of the air conditioner caused by factors such as installation environment is solved, the detection of the indoor environment temperature is assisted, the heating recovery efficiency after the heating shutdown is improved, and the accuracy and the reasonability of the determination of the actual indoor environment temperature are improved.
By calculating the average attenuation temperature difference of each period and calculating the attenuated inner ring temperature corresponding to the initial indoor temperature according to the initial temperature difference and the accumulated temperature drop generated by the average attenuation temperature difference of each period, the actual temperature condition of the initial indoor temperature after temperature attenuation and reduction can be accurately reflected, and then whether the current heating recovery condition is met or not can be accurately judged, and the heating comfort is prevented from being influenced due to the fact that the current indoor environment temperature detected by the air conditioner is inaccurate.
In a possible implementation manner, the method provided in this embodiment further includes: and if the minimum temperature value is greater than the preset recovery temperature, detecting the current indoor environment temperature of the next period, calculating the average attenuation temperature difference of the next period and the inner ring temperature after attenuation until the air conditioner meets the recovery heating condition, and controlling the air conditioner to recover the heating operation.
In each detection period, if the minimum temperature value of the current indoor environment temperature and the attenuated inner ring temperature in the current period is greater than the preset recovery temperature, indicating that the heating recovery condition is not met, continuing temperature judgment, namely detecting the current indoor environment temperature of the next period, calculating the attenuated inner ring temperature of the next period according to the current indoor environment temperature of the next period so as to further judge whether the heating recovery condition is met, periodically executing temperature detection and judging whether the heating recovery condition is met until the air conditioner meets the heating recovery condition, and controlling the air conditioner to recover heating operation.
Through when unsatisfied the condition of heating that resumes, the judgement of repeatedly carrying out temperature detection and the condition of heating that resumes avoids the too much reduction of indoor ambient temperature to make the user produce the cold sensation, has guaranteed indoor ambient temperature's travelling comfort, has promoted user experience.
According to the air conditioner heating temperature-reaching shutdown control method provided by the embodiment, through increasing the calculation of the attenuated inner ring temperature, when the detected current indoor environment temperature does not meet the heating recovery condition, but the calculated value of the attenuated inner ring temperature meets, the heating recovery is also controlled, the problem of difficulty in heating recovery after heating shutdown caused by factors such as installation environment and the like can be reduced, the heating recovery efficiency after heating shutdown is improved, and the comfort of the indoor environment is improved.
