The specific embodiment of the air conditioner of the present invention is substantially the same as the following embodiments of the control method of the air conditioner, and will not be described herein again.
Referring to fig. 2, fig. 2 is a schematic flowchart of a control method of an air conditioner according to a first embodiment of the present invention, the control method of the air conditioner including:
and step S10, acquiring the indoor environment temperature after the air conditioner enters the heating mode.
The terminal of the embodiment of the invention is an air conditioner, which comprises an indoor unit and an outdoor unit, wherein a temperature sensor is arranged in the indoor unit and used for detecting the indoor environment temperature. The air conditioner can realize the switching of different modes such as a heating mode, a cooling mode, a dehumidification mode, a ventilation mode and the like under the control instruction of a user. When the air conditioner receives a control instruction triggered by a user and enters a heating mode, the control instruction triggered by the user is analyzed, and a heating target temperature set by the user, namely an indoor set temperature, is obtained. Meanwhile, the air conditioner acquires the detected indoor environment temperature in real time through the temperature sensor.
It should be noted that the obtained indoor environment temperature may be an indoor environment temperature at the current time, or may be an indoor environment temperature within a preset time period, and an average value calculated based on the indoor environment temperature within the preset time period.
And step S20, when the indoor environment temperature meets a first preset condition, controlling the indoor environment temperature without stopping.
After the indoor environment temperature and the indoor set temperature are obtained, the obtained indoor environment temperature and the indoor set temperature are compared in real time, the difference value of the two is calculated, and whether the indoor environment temperature meets the control condition that the temperature does not stop is judged according to the difference value, namely the first preset condition is judged. It should be noted that the first preset condition is preset by a user, and during the setting, the setting may be performed according to a range of the difference, for example, when the indoor environment temperature is detected to be greater than the indoor set temperature, it is determined that the first preset condition is satisfied, or when the indoor environment temperature is detected to exceed a certain set value of the indoor set temperature, it is determined that the first preset condition is satisfied, and the like, or the setting may be performed according to the difference and the duration, for example, when the indoor environment temperature is detected to be greater than the indoor set temperature, and the duration is greater than 1min, it is determined that the first preset condition is satisfied, and the like. The first preset condition may be set according to actual requirements, and this embodiment is not specifically limited.
Optionally, the first preset condition in this embodiment includes: indoor set temperature TSetting upTemperature T of indoor environmentInner ringIs less than or equal to a first temperature threshold, or a room set temperature TSetting upTemperature T of indoor environmentInner ringIs less than or equal to the second temperature threshold and the duration is greater than the first time threshold, or the indoor set temperature TSetting upTemperature T of indoor environmentInner ringThe difference value of (a) is less than or equal to a third temperature threshold, and the duration is greater than a second time threshold, wherein the first temperature threshold, the second temperature threshold and the third temperature threshold are all negative numbers, the first temperature threshold is less than the second temperature threshold, the second temperature threshold is less than the third temperature threshold, and the first time threshold is less than the second time threshold. For example, assuming that the first temperature threshold is-4 deg.C, the second temperature threshold is-3 deg.C, the third temperature threshold is-2 deg.C, the first time threshold is 1min, and the second time threshold is 2min, then when T isSetting up-TInner ringLess than or equal to-4 ℃; or TSetting up-TInner ringAt the temperature of less than or equal to-3 ℃ and the duration time is more than 1 min; or TSetting up-TInner ringThe temperature is less than or equal to minus 2 ℃, the duration is more than 2min, and when any one of the three conditions is met, the control condition that the temperature is reached without stopping is met.
Those skilled in the art can understand that the foregoing examples are used for illustration and do not represent actual values, and the first temperature threshold, the second temperature threshold, the third temperature threshold, the first time threshold, and the second time threshold may be set to other values according to actual needs, and the embodiment is not particularly limited.
When the indoor environment temperature meets a first preset condition, the air conditioner exits the original heating mode, and is switched to a non-stop control mode for reaching the temperature, so that the non-stop control for reaching the temperature is carried out. In the temperature-reaching non-stop control mode, the air conditioner still continuously obtains the indoor environment temperature, and controls the running frequency of the compressor and the air outlet grade of the indoor fan according to the difference range of the indoor environment temperature and the indoor set temperature. Specifically, the difference value is divided into different interval ranges, and the operating frequency of the compressor is controlled to be reduced to a corresponding frequency according to the difference value interval range, for example, when the difference value between the indoor environment temperature and the indoor set temperature is greater than a certain interval range, the operating frequency of the compressor needs to be reduced at this time, and the heat production amount of the air conditioner is reduced. Simultaneously, the temperature of the coil pipe in the indoor unit is considered, the air outlet windshield of the indoor fan needs to be correspondingly set, if the temperature of the inner coil pipe is lower than the temperature of the cold air prevention inner pipe, the air outlet temperature is possibly lower for preventing the influence on the heating comfort experience of a user, and the air outlet windshield of the indoor fan is reduced at the moment.
The obtained indoor environment temperature is compared with the indoor set temperature in the embodiment, whether the indoor environment temperature of the air conditioner meets a first preset condition or not is judged from the result, and after the first preset condition is met, the air conditioner enters the temperature-reaching non-stop machine control mode, so that the running frequency of the compressor and the air outlet windshield of the indoor fan are correspondingly controlled according to the difference range of the indoor environment temperature and the indoor set temperature, the compressor is not stopped, the electric quantity loss caused by frequent stop of the compressor is avoided, and the comfort experience of heating in winter of a user is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of an air conditioner according to a second embodiment of the present invention, and based on the embodiment illustrated in fig. 2, after the step S10 of acquiring the indoor ambient temperature, the method further includes:
and step S30, stopping the temperature-reaching non-stop control when the indoor environment temperature meets a second preset condition, wherein the second preset condition is that the difference value between the indoor set temperature and the indoor environment temperature is greater than or equal to a fourth temperature threshold value, and the fourth temperature threshold value is a positive number.
When the air conditioner detects the indoor ambient temperature TInner ringSatisfying a second predetermined condition, i.e. indoor set temperature TSetting upOut of room ambient temperature TInner ringAt a certain set value, due to the indoor ambient temperature TInner ringWhen the temperature is lower than the indoor set temperature and the heating function of the air conditioner needs to be started for heating, the air conditioner exits the temperature-reaching non-stop control mode at the moment and is switched back to the heating mode before entering the temperature-reaching non-stop control mode. It should be noted that the second preset condition is the indoor set temperature TSetting upTemperature T of indoor environmentInner ringIs greater than or equal to a fourth temperature threshold that is positive, e.g., assuming the fourth temperature threshold is 2 ℃, then TSetting up-TInner ringAnd when the temperature is more than or equal to 2 ℃, controlling the air conditioner to return to the original heating mode.
Those skilled in the art will understand that the foregoing examples are for illustration and do not represent actual values, and the fourth temperature threshold may be set to other values according to actual needs, and the embodiment is not particularly limited.

When the indoor ambient temperature satisfies the first preset condition, since the indoor ambient temperature exceeds the indoor set temperature, the heating capacity of the air conditioner needs to be reduced, and thus the operating frequency of the compressor needs to be reduced. In the process of reducing the operating frequency of the compressor, the compressor can be directly controlled to reduce the lower limit frequency under the current working condition, and the operating frequency of the compressor can also be reduced to the preset frequency according to the difference value between the indoor environment temperature and the indoor set temperature.

Specifically, the step S60 includes:
step S601, obtaining a current operating frequency of a compressor in the air conditioner.
Step S602, determining a preset frequency corresponding to a difference between the indoor ambient temperature and the indoor set temperature.
The corresponding relation table between different difference value ranges and the operating frequency is preset in the air conditioner, and the air conditioner can obtain the preset frequency corresponding to the different difference value ranges according to the corresponding relation table when the air conditioner reaches a temperature non-stop control mode. Therefore, in the process of reducing the operating frequency of the compressor, a difference between the indoor ambient temperature and the indoor set temperature needs to be calculated, and the preset frequency corresponding to the difference is determined according to the difference between the indoor ambient temperature and the indoor set temperature.
Step S603, comparing the current operating frequency of the compressor with the preset frequency, and determining whether the current operating frequency of the compressor reaches the preset frequency.
And comparing the acquired current running frequency of the compressor with the preset frequency, and judging whether the current running frequency of the compressor reaches the preset frequency. If the preset frequency is not reached, executing step S604; if the predetermined frequency is reached, step S605 is executed.
Step S604, reducing the operating frequency of the compressor, taking the reduced operating frequency as the current operating frequency of the compressor, and returning to the step: acquiring the current operating frequency of a compressor in the air conditioner.
And when the current operating frequency of the compressor does not reach the preset frequency, controlling the operating frequency of the compressor to be reduced, taking the reduced operating frequency of the compressor as the next current operating frequency of the compressor, returning to the step S601, and circularly executing the judging step until the current operating frequency of the compressor reaches the preset frequency.
Step S605, keeping the current operating frequency of the compressor unchanged.
When the current operating frequency of the compressor reaches the preset frequency, the operating frequency of the compressor does not need to be adjusted, and at the moment, the current operating frequency of the compressor is kept unchanged.
The air conditioner performs step S604 or step S605 according to the judgment result, so that the final operating frequency of the compressor is reduced to the preset frequency.
In this embodiment make the heating volume of air conditioner reduce through the operating frequency who reduces the compressor, even after the air conditioner reaches indoor settlement temperature, can not cause the compressor to close yet to avoid the air conditioner to reach the warm shutdown, save the electric quantity loss.

and step S801, when the current temperature in the inner coil pipe is smaller than a fifth temperature threshold value, the air outlet gear of the indoor fan is lowered.
If the current temperature T in the inner coil pipeInner pipeLess than the fifth temperature threshold value, then it is lower to indicate the temperature of interior coil pipe, if the air-out of indoor fan was kept out the wind highly this moment, and the wind temperature that blows out is lower relatively, can let the user feel cold wind and blow the people, consequently need turn down the air-out shelves of indoor fan, avoids because air-out temperature probably is lower, influences the user and heats the travelling comfort and experience.
