The invention is described in detail below with reference to the figures and alternative embodiments.
As shown in fig. 1, as an embodiment of the present invention, a method for controlling an air conditioner to adjust a room temperature is disclosed, which includes:
step A: the air conditioner receives an instruction to operate in a first operation mode, and detects the current time and the return air temperature of an indoor unit of the air conditioner;
and B: when the current time is the first time and the return air temperature of the indoor unit of the air conditioner meets the first condition, the air conditioner operates according to the set temperature;
and C: when the set temperature meets the second condition and/or the return air temperature of the indoor unit of the air conditioner meets the third condition and lasts for the second time, adjusting the set temperature to increase or decrease the first temperature adjusting value at intervals of the third time;
step D: and when the set temperature meets the fourth condition and/or the return air temperature of the indoor unit of the air conditioner meets the fifth condition, stopping adjusting the set temperature and keeping the current set temperature.
In step B, the set temperature refers to a temperature set by a user, for example, the user sets the set temperature at 26 ℃ by a tool such as a remote controller.
The second time may be, for example, 5min, 8min, 10min, 15min, 30min, etc., and may be set as needed, which is not particularly limited. Preferably, the second time is 5 min. When the general air conditioner just started to operate, the user has a large demand for refrigeration, for example, just enters from the outside and is hot, after the refrigeration generally takes about 5min, the indoor temperature can approach or reach the set temperature, the demand of the user for refrigeration is also reduced, then the adjustment of the set temperature is started, and the user experience is better.
The third time may be, for example, 10min, 20min, 30min, 40min, 60min, etc., and may be set as needed, which is not particularly limited. Preferably, the third time is 30 min. After the air conditioner operates for a period of time, the requirement of a user on refrigeration is reduced, the set temperature which is finally suitable can be gently reached and maintained at intervals of 30min, the adjusting frequency of the set temperature is proper, the temperature change fluctuation is small, the change of the temperature is not easy to be perceived by the user, and the user experience is better.
The first temperature adjustment value may be, for example, 1 ℃, 2 ℃, 3 ℃, etc., and may be optionally set according to needs, without specific limitation. If the first temperature adjustment value is 1 ℃, the set temperature is increased or decreased by 1 ℃ every third time.
The first operation mode may include a cooling mode, a heating mode, etc., but is not particularly limited. The air conditioner can acquire the current time through networking and can also acquire the current time through direct setting of a user, the implementation means is not specifically limited, and the setting can be selected according to needs.
The control method for adjusting the room temperature of the air conditioner comprises the steps that the air conditioner operates in a current operation mode, the current time and the return air temperature of an indoor unit of the air conditioner are detected, the set temperature is adjusted at intervals after the air conditioner operates for a certain time according to the current time and the return air temperature according to the set temperature, and the set temperature is gradually adjusted to be the proper set temperature under the current mode, the current time and the current operating time of the air conditioner and is kept.

For example, when the detected time is 8:00-22:00, the return air temperature of the indoor unit of the air conditioner is greater than 26 ℃, the demand of a user on the refrigerating capacity is high, the air conditioner operates according to the set temperature of the user, timing is started after the set temperature is less than 26 ℃ and/or the return air temperature is less than 26 ℃ for 5 minutes, the set temperature is increased by 1 every 30 minutes until the set temperature is equal to 26 ℃ or the return air temperature is equal to 26 ℃, the intelligent set temperature regulation control is ended, and the current set temperature is kept. The output of an outdoor unit compressor is reduced by increasing the set temperature of the indoor unit, the energy consumption of the air conditioner is reduced, and meanwhile, the indoor temperature of the air conditioner is stabilized in an optimal comfortable temperature range recommended by indoor air quality standard.
Specifically, the first operation mode is a cooling mode, and the step C further includes:

And if the second temperature regulation value is 1 ℃, increasing the inlet temperature of the heat exchanger by 1 ℃ every third time.
The step D also comprises the following steps:

For example, when the detected time is 22:00-24:00 or 0:00-8:00, the return air temperature of the indoor unit of the air conditioner is greater than 28 ℃, the demand of a user on the refrigerating capacity is high, the air conditioner operates according to the set temperature of the user, timing is started after the set temperature is less than 28 ℃ and the return air temperature is less than 28 ℃ for 5 minutes, the set temperature is increased by 1 ℃ and the inlet temperature of the heat exchanger is also increased by 1 ℃ every 30 minutes until the set temperature is equal to 28 ℃ or the return air temperature is equal to 28 ℃, the intelligent regulation control of the set temperature and the inlet temperature of the heat exchanger is finished, and the current set temperature and the inlet temperature of the heat exchanger are kept.

For example, when the detected time is 8:00-22:00, the return air temperature of the indoor unit of the air conditioner is less than 20 ℃, the demand of a user on heating capacity is large, the air conditioner operates according to the set temperature of the user, timing is started after the set temperature is greater than 20 ℃ and the return air temperature is greater than 20 ℃ for 5 minutes, the set temperature is increased by 1 ℃ every 30 minutes until the set temperature is equal to 20 ℃ or the return air temperature is equal to 20 ℃, the intelligent set temperature regulation control is ended, and the current set temperature is kept. The output of an outdoor unit compressor is reduced by reducing the set temperature of the indoor unit, the energy consumption of the air conditioner is reduced, and meanwhile, the indoor temperature of the air conditioner is stabilized in an optimal comfortable temperature range recommended by indoor air quality standard.
