Because the air conditioner is arranged in the first room and is provided with the upper air channel leading to the kitchen, the operation information of the air conditioner is acquired, and the air outlet mode of the air conditioner is controlled according to the operation information of the air conditioner, so that the first room and the kitchen can be controlled more comprehensively and intelligently.
The temperature difference between the kitchen temperature and the outdoor temperature can reflect whether the environment of the kitchen is suitable or not, when the kitchen temperature is higher than the outdoor temperature, the kitchen is more sultry, users feel uncomfortable easily, the compressor is controlled to run at a higher frequency, the temperature in the kitchen can be reduced rapidly, and the comfort level of the users is improved. Wherein the operating frequency of the compressor may also be controlled in dependence of the temperature difference between the kitchen temperature and the first room temperature.
According to the air conditioner control method provided by the invention, the operation of the air conditioner is conveniently controlled in a proper environment by determining that the range hood or the kitchen range is opened and the temperature in the kitchen is greater than or equal to the first preset temperature; the air outlet mode of the air conditioner is controlled according to the operation information of the air conditioner, so that the temperature adjusting effect of the first room and the kitchen is considered; the operation frequency of the compressor of the air conditioner is controlled according to the temperature difference between the kitchen temperature and the outdoor temperature, so that the operation state of the air conditioner can be dynamically and flexibly adjusted, the intelligent degree of the air conditioner is improved, and the control efficiency of the air conditioner is improved.
Specifically, the air conditioner comprises a casing 10, an upper air port 101 is formed in the top of the casing 10, a lower air port 102 is formed in the bottom of the casing, and an upper air port 103 and a lower air port which are distributed up and down are formed in a front panel 105 of the casing 10. The upper air outlet 101, the lower air outlet 102, the upper air outlet 103 and the lower air outlet can be opened or closed. The top of the housing 10 is connected with an upper duct 106, and the upper duct 106 can be communicated with or closed off the upper tuyere 101.
According to the operation information of the air conditioner, the air outlet mode of the air conditioner is controlled, and the method specifically comprises the following steps:
and if the air conditioner is not started, controlling the air conditioner to be started, and controlling the air conditioner to operate in a first kitchen refrigerating mode.
Wherein, in the first kitchen cooling mode, the upper air outlet 103 and the lower air outlet are closed, the lower air outlet 102 is opened, the upper air duct 106 and the upper air outlet 101 are opened with a first opening degree, and the upper air duct 106 is communicated with the upper air outlet 101, so that air flow enters the shell 10 from the lower air outlet 102 and flows out from the upper air duct 106.
If the air conditioner is not started, the first room has no heat exchange requirement, so that the air conditioner is controlled to operate in a first kitchen refrigerating mode, and only cold air is blown to the kitchen, so that the temperature in the kitchen is reduced.
The air conditioner is a wall-mounted air conditioner, and a surface opposite to the front panel 105 is mounted on a wall surface. The air conditioner further includes a blower 30, and the blower 30 is located in the housing 10 and can rotate in a forward direction or a reverse direction to change the direction of air flow. Specifically, the fan 30 is a cross flow fan. In the first kitchen cooling mode, the fan 30 rotates reversely, the lower air inlet 102 serves as an air inlet, air flow is sucked from the outside of the air conditioner, the upper air inlet 101 serves as an air outlet, and cold air generated after heat exchange enters the kitchen environment from the upper air duct 106 under the action of the fan 30.
Further, according to the operation information of the air conditioner, controlling the air outlet mode of the air conditioner, further comprising:
and if the air conditioner is started and the refrigerating mode is operated, controlling the air conditioner to operate in a second kitchen refrigerating mode.
In the cooling mode, the upper air port 101, the upper air duct 106 and the lower air port 103 are closed, the lower air port 102 and the upper air port 103 are opened, and the blower 30 is reversely rotated so that air flows from the lower air port 102 into the housing 10 and out of the upper air port 103, and the air conditioner blows cool air only to the first room.
In the second kitchen cooling mode, the lower air outlet is closed, the lower air outlet 102 and the upper air outlet 103 are opened, the upper air duct 106 and the upper air outlet 101 are opened at a second opening degree, and the upper air duct 106 is communicated with the upper air outlet 101 so that air flow enters the shell 10 from the lower air outlet 102 and flows out from the upper air duct 106 and the upper air outlet 103, wherein the second opening degree is smaller than the first opening degree.
If the air conditioner is started and the refrigerating mode is operated, the first room also has a refrigerating requirement, and the air conditioner is controlled to be switched to the second kitchen refrigerating mode, and meanwhile cold air is blown to the first room and the kitchen. In the second kitchen cooling mode, the blower 30 rotates in a reverse direction, so that a part of cool air is discharged into the first room through the upper air outlet 103 and a part of cool air is discharged into the kitchen through the upper air duct 106. Wherein, through controlling the opening of the lower air opening 102 and the upper air opening 101 with the smaller second opening degree, a large amount of cold air can be prevented from being discharged into the kitchen, and the refrigerating effect in the first room is prevented from being influenced.
In a specific embodiment, the second opening is 30% -50% of the first opening. For example, in the case where the first opening degree is 100%, the second opening degree may be 30%, 40%, 50%.
Wherein the air conditioner further comprises an evaporator 20, the evaporator 20 is movably installed in the housing 10, and the evaporator 20 is located near the air outlet 102 in the cooling mode, the first kitchen cooling mode or the second kitchen cooling mode.
In the cooling mode, the first kitchen cooling mode or the second kitchen cooling mode, the airflow flows upward from the air outlet 102, so that the evaporator 20 is arranged at a position close to the air outlet 102, which is beneficial to heat exchange of the sucked airflow by the evaporator 20 and improves the cooling efficiency.
In one embodiment, as shown in fig. 2, the method for controlling an air conditioner provided in the embodiment of the present invention further includes:
s40: in the first kitchen cooling mode, controlling the fan 30 of the air conditioner to operate at a first rotational speed, and controlling the target temperature of the air conditioner to be a second preset temperature; in the second kitchen cooling mode, the fan 30 of the air conditioner is controlled to operate at a second rotational speed, and the target temperature of the air conditioner is controlled to be a third preset temperature.
The first rotating speed is smaller than the second rotating speed, the second preset temperature and the third preset temperature are smaller than the first preset temperature, and the second preset temperature is larger than the third preset temperature.
In a specific embodiment, the first rotational speed is 1200RPM, the second rotational speed is 1300RPM, the first preset temperature is 35 ℃, the second preset temperature is 18 ℃, and the third preset temperature is 16 ℃.
In the case where the air conditioner operates in the first kitchen cooling mode, the air conditioner cools only the kitchen, and thus the control fan 30 operates at a smaller first wind speed, and the target temperature of the air conditioner is controlled to be a larger second preset temperature. In the case that the air conditioner operates in the second kitchen cooling mode, the air conditioner needs to cool the first room and the kitchen at the same time, so that the fan 30 of the air conditioner is controlled to operate at a second larger rotation speed, cool air is blown to the first room and the kitchen at the same time, and the target temperature of the air conditioner is controlled to be a third smaller preset temperature, so that the cooling intensity is increased.
In step S30, controlling an operation frequency of a compressor of the air conditioner according to a temperature difference between a kitchen temperature and an outdoor temperature, including:
s31: acquiring a temperature difference delta T between the kitchen temperature and the outdoor temperature;
s32: determining an initial frequency F0 according to an air outlet mode of the air conditioner;
s33: determining the operation frequency F of the compressor according to the initial frequency F0 and the temperature difference delta T, and controlling the compressor to operate at the operation frequency F, wherein the relation between the operation frequency F and the initial frequency F0 and the temperature difference delta T is as follows:
F=F0+ΔT；
Wherein, the relation between the temperature difference delta T and the kitchen temperature and the outdoor temperature is as follows:
ΔT=T1-T2；
wherein T1 is the kitchen temperature, and T2 is the outdoor temperature.
It is understood that the higher the kitchen temperature is relative to the outdoor temperature, the higher the operation frequency of the compressor is, and the faster the cooling rate of the air conditioner is. As the operation time of the air conditioner increases, the kitchen temperature gradually decreases, and when the kitchen temperature is lower than the outdoor temperature, the operation frequency F of the compressor decreases as the kitchen temperature decreases, thereby saving energy while ensuring the refrigerating effect.
