Background
An air conditioner is a common household appliance, and with the progress of society and the increase of people's demand, the air conditioner has been greatly developed in terms of system performance. Generally, the air conditioner is hot in summer and stuffy indoors, the requirement of a user cannot be met at the moment when the air conditioner is just opened, the air conditioner is also hot compared with the outdoor air, and the user generally takes the air out after the air conditioner is opened and then returns. Because the air conditioner cannot meet the requirement of a user on cooling capacity when being started, a pre-cooling process (including remotely starting the air conditioner before a person enters a room or starting the air conditioner after the person enters the room and then leaves the room) is often carried out. However, a long pre-cooling time may result in a long waiting time for the user, and thus the rapid cooling mode is usually enabled.
At present, the air conditioner is operated in a rapid cooling mode manually, on one hand, the air conditioner cannot save energy due to single exit condition, and on the other hand, the air conditioner is easy to cause the problems of catching cold and catching a cold of people who enter a room. When the set temperature of the air conditioner needs to be changed and the rapid cooling mode operation needs to be exited, the set temperature of the air conditioner can be manually adjusted only, and great inconvenience is brought. In addition, sometimes the indoor temperature reaches the normal use requirement, but the user increases the power consumption operation of the air conditioner due to lack of perception of the indoor temperature, which also causes the problem of energy saving.

FIG. 1 is a schematic view of the main flow of the air conditioner operation control according to the present invention;
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In a first aspect of the present invention, a method for controlling an air conditioner operation is provided, and a main process thereof can be seen in fig. 1. The air conditioner operation control method comprises the following steps:
s1, judging whether a person is in the room or not after the air conditioner is started (for example, through an infrared device or other biological recognition devices);
s2, if no person is judged to be in the room, the operation goes to S3; and if the indoor people are judged, adjusting the air outlet of the air conditioner to blow air in the direction pointing to the area where the people are located.
S3, detecting the room temperature and judging whether the current room temperature is greater than the preset temperature; if so, controlling the air conditioner to operate in a first rapid cooling mode; if not, the air conditioner is controlled to stably operate according to the set temperature (such as the temperature set on the remote controller).
Wherein the preset temperature is preferably equal to or higher than 30 ℃. It should be noted that the preset temperature is used to measure the room temperature, and is not the temperature set by the air conditioner (e.g., the temperature set on the remote controller).
S4, when a first condition or a second condition is met, the air conditioner exits from the first rapid cooling mode;
the first condition is: detecting that the room temperature is less than 0.9 times of the preset temperature;
the second condition is: a person is detected in the room.
That is, the first rapid cooling mode may be exited when the detected room temperature is less than 0.9 times the preset temperature (assuming that the preset temperature is 30 ℃, the detected room temperature is less than 27 ℃); or directly quitting the first rapid cooling mode when a person is detected in the room.
However, when a person is detected in the room, several determination steps may be further performed to determine whether to exit the first rapid cooling mode. Thus, the present invention preferably causes the step S4 to include:
s4-1, when the second condition is satisfied but the first condition is not satisfied, the air conditioner continues to operate in the first rapid cooling mode for a first preset time (for example, 20 seconds), and after the first preset time, it is determined whether the second condition is still satisfied. When people are in the room but the room temperature does not meet the first condition, the air conditioner continues to operate for a period of time in the rapid cooling mode, and then whether people are in the room or not is judged.
And S4-2, if the second condition is still met after the first preset time, the air conditioner exits the first rapid cooling mode. Namely, the indoor people are judged again, and the air conditioner is directly quitted from the rapid cooling mode without considering the factor of the room temperature, so that the indoor people are prevented from catching a cold and catching a cold.
Preferably, in the step S4-2, after the air conditioner exits from the first rapid cooling mode, the air conditioner is not controlled to stably operate at the set temperature, but to operate at the temperature which is the longest previous air conditioner operation time and is stored in the air conditioner in a memory.
Further, the step S4-2 may further include: and after the first preset time, if the second condition is not met, further judging whether the first condition is met, operating in a second rapid cooling mode before the first condition is met, and exiting the second rapid cooling mode until the first condition is met. Namely, after a first preset time, judging to find that: the person in the room leaves. And at the moment, whether the room temperature meets the first condition is further judged, if not, the rapid cooling mode is continuously operated to lower the room temperature, so that the rapid cooling mode is ended as soon as possible to achieve the purpose of saving energy and enable the leaving people to return to the room again, and the user experience is improved. Preferably, the second rapid cooling mode with higher operation intensity is adopted to continue cooling, so as to achieve the aim of cooling more quickly and reduce the waiting time of the user.
Or in another way: if the second condition is not met after the first preset time and the second condition is judged to be not met again after the second preset time (such as 5 seconds), the air conditioner operates in the second rapid cooling mode and detects the position of the indoor door so as to adjust the direction of the air outlet of the air conditioner pointing to the door. That is, after the first preset time, a second preset time is passed, and if the person who leaves does not come back yet, it is reflected that the indoor temperature is still too high to meet the user requirement, so that the user still does not want to come back indoors (this is derived from the situation that no person exists in the two preset time periods, and is not based on the result of the room temperature detection). In this case, it is also preferable to use the second rapid cooling mode with higher operation intensity to achieve the cooling target more quickly and reduce the waiting time of the user. Preferably, the second preset time is less than the first preset time.
In addition, the air outlet direction of the whole air conditioner is close to the door (people leaving the room usually wait for the indoor cooling near the door) so as to accelerate the cooling speed near the door, so that a user can feel cool when the user is near the door or tries to enter the room again, and the user is willing to stay indoors, so that the second condition is met in the subsequent circulating judgment to trigger the exit of the rapid cooling mode, and the energy is saved.
In the present invention, it is preferable that the compressor, the expansion valve, and the fan of the air conditioner are all in the maximum operation state in the second rapid cooling mode. And in the first rapid cooling mode, the compressor, the expansion valve and the fan of the air conditioner are all in a large working state (higher than that of the air conditioner which stably operates according to the set temperature, but lower than that of the second rapid cooling mode).
Preferably, the air conditioner of the present invention emits a warning sound after exiting the first or second rapid cooling mode to remind the user that the user can enter the room.
As a second aspect of the present invention, there is provided an air-conditioning operation control device for implementing the above-described air-conditioning operation control method, the air-conditioning operation control device including:
the human body judging module is used for judging whether a person is in the room;
the room temperature detection module is used for detecting the current room temperature and judging whether the current room temperature is greater than the preset temperature;
and the operation mode control module is used for controlling the air conditioner to operate in a specified operation mode.
The specified operation mode includes: a first rapid cooling mode, a second rapid cooling mode, an operation mode according to a set temperature, a temperature operation mode with the longest previous air conditioner operation time, and the like.
As a third aspect of the present invention, there is provided an air conditioner including an indoor unit including the air conditioning operation control device described above.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
