People have higher dependence on air conditioners, and along with the continuous improvement of user demands, the requirements on the air conditioners are higher, so that the functions of the air conditioners are required to be continuously and variously developed and improved according to the user demands.
Taking the condensation problem of the air conditioner as an example, the dew point temperature of the indoor air in summer is higher, when the air supply temperature of the air conditioner is lower than the indoor dew point temperature, and the humidity value of the indoor air is larger, the air supply of the air conditioner is blown onto the air deflector due to the temperature difference effect, so that the condition of water vapor condensation can be generated. Dew and water dripping are generated at the air outlet and the air duct of the air conditioner.
In addition, many users now prefer to use a low wind speed mode in which the supply of air from the air conditioner is softer, and at the same time, the air temperature can be adjusted. However, in the low wind speed mode, the wind speed of the air conditioner is very low, the air outlet is small, and if the indoor humidity is too high, the possibility of dew condensation and condensed water dripping is higher. The generation of condensation not only causes trouble to the use of users, but also affects the use environment, and the conditions have great influence on the user experience.
In order to solve the problem of condensation, in the prior art, some air conditioners limit the size of an air outlet under a low wind field, namely limit the position of a lower air deflector, so that the air outlet is increased, namely the air speed and the angle of air supply of the air conditioner are adjusted, and the possibility of the occurrence of the condensation can be reduced to a certain extent, but the problem of the occurrence of the condensation cannot be completely solved. However, this scheme also limits the choice of users, some users do not like to use the large air outlet mode, if the size of the air outlet is directly limited, the users cannot adjust the air outlet to be smaller, and the user experience of some users can be directly affected.

Referring first to fig. 1, the anti-condensation control method for an air conditioner of the present invention will be described. Wherein fig. 1 is a main flow chart of an embodiment of an anti-condensation control method for an air conditioner according to the present invention.
In order to solve the problem of condensation of the existing air conditioner and simultaneously ensure user experience, the condensation prevention control method for the air conditioner comprises the following steps:
step S100, detecting the wind speed of the air conditioner and the position of the air deflector 7.
Step S200, when the wind speed is the first wind speed and the position of the air deflector 7 is located at the first opening, a request for obtaining the humidity value of the indoor air is sent.
Specifically, a control module is arranged in the air conditioner, and can detect the running mode of the air conditioner, confirm the wind speed of the air conditioner through the running state of the fan and detect the current position of the air deflector 7. When the air conditioner detects that the current wind speed is low wind or breeze and the air deflector 7 is at a small angle, judging that the air conditioner has condensation risk. As shown in fig. 2, the air deflector position 1 and the air deflector position 2 both belong to small-angle positions, and the air deflector position 5 is the maximum opening position of the air conditioner.
Step S300, acquiring a humidity value of the indoor air.
Specifically, a humidity sensor is arranged in the air conditioner, and the air conditioner controls the humidity sensor to acquire humidity information of indoor air.
Step S400, comparing the humidity value of the indoor air with a first threshold value and a second threshold value.
Specifically, the control module in the air conditioner compares the humidity value of the indoor air with a first threshold value and a second threshold value.
In step S510, when the humidity value of the indoor air is less than the first threshold value, the air conditioner keeps the first opening degree and the first wind speed running.
Specifically, in a preferred technical scheme, when the first threshold is 35% and the indoor humidity is less than 35%, the default air conditioner will not generate condensation, and the air conditioner continues to operate according to the original operation mode, i.e. the air speed of the air conditioner is low wind or breeze, and the air deflector 7 is located at the air deflector position 1 or the air deflector position 2.
In step S520, when the humidity value of the indoor air is within the first threshold value and the second threshold value, the air conditioner is controlled to enter a first anti-condensation mode.
Specifically, when the air conditioner detects that the humidity value of the indoor air is within the first threshold value and the second threshold value, the air conditioner is judged to have the possibility of condensation generation, and then the air conditioner is controlled to enter a first condensation prevention mode.
Wherein the first anti-condensation mode includes:
step S600, controlling the air conditioner to detect whether a person is in the room.
Specifically, a detection device is arranged in the air conditioner and can detect whether a person exists indoors.
The detection modes are various. In a preferred embodiment, the detection device may be an infrared sensor. In a further preferred embodiment, the detection device is a radar sensor.
Step S710, when a person exists in the room, after waiting for a first time, switching the air deflector 7 of the air conditioner from a first opening degree to a second opening degree, from a first air speed to a second air speed, and after lasting for a second time, recovering to the first opening degree and the first air speed;
wherein the first opening is less than the second opening; the first wind speed is less than the second wind speed; the first threshold value is a set value that the air conditioner does not need to enter the anti-condensation, and the second threshold value is a set value that the air conditioner needs to enter the anti-condensation; the first time decreases as the humidity value increases.
Specifically, when the air conditioner detects that the humidity value of the indoor air is greater than 35%, the air conditioner is considered to have the risk of generating condensation, and the first condensation prevention mode needs to be entered. The first threshold is a set value that the air conditioner does not need to enter the anti-condensation mode, that is, the air conditioner defaults to have no risk of condensation under the condition that the first threshold is lower than the set value. The second threshold is a set value that the air conditioner must enter the anti-condensation mode, namely when the humidity value of the indoor air is larger than the second threshold, the possibility of condensation of the air conditioner is considered to be high at the moment, and the air conditioner needs to enter the anti-condensation mode to control the condensation of the air conditioner.
In a preferred embodiment, the second threshold is 70% and the second time is 1min. When the humidity value of the indoor air is between 35% and 70%, and the indoor people are detected by the detection device, the air conditioner is controlled to enter a first condensation preventing mode. That is, the air conditioner control module controls the air conditioner to control the air deflector 7 to the maximum position, namely the air deflector position 5 in fig. 2, after the humidity value of the indoor air is between 35% and 70% for the first time, and switches the wind speed to be high, and after the operation state is maintained for 1min, the air conditioner resumes the original operation mode that the wind speed is low or breeze, and the air deflector 7 is positioned at the air deflector position 1 or the air deflector position 2.
Wherein, a calculation formula is obtained through the research of the inventor to determine the first time: first time= (70-N) ×a, N is the current indoor air humidity value, and a is the coefficient. In a preferred embodiment, A has a value of between 1 and 1.5, preferably 1.2.
The air conditioner can be in sensing indoor someone's state under, with first anti-condensation mode (namely control aviation baffle 7 to aviation baffle position 5, switch the wind speed simultaneously and be high wind for 1 min) as far as possible postpone, effectively avoided high wind and aviation baffle 7 action to cause user's discomfort. In the limit state, namely after the first time, the position and the wind speed of the air deflector 7 of the air conditioner are adjusted, and the operation state is kept for 1min, so that the problem of condensation is solved, the experience of a user can be better maintained, and meanwhile, the generation of the condensation can be effectively avoided. After 1min, the air conditioner recovers the original running mode that the wind speed is low or breeze and the air deflector 7 is positioned at the air deflector position 1 or the air deflector position 2.
And step S720, when no person is detected in the room, controlling the air conditioner to enter a second anti-condensation mode.
The second anti-condensation mode specifically includes:
after waiting the third time, controlling the air deflector 7 of the air conditioner to switch from the first opening degree to the second opening degree, and from the first wind speed to the second wind speed, and after the second time, recovering to the first opening degree and the first wind speed.
Specifically, when the air conditioner detects that no person is in the room, the corresponding second anti-condensation mode can be directly entered according to the humidity condition of the indoor air, namely, when the humidity value of the indoor air is within the first threshold value to the second threshold value.
In a preferred embodiment, the third time is 10 minutes. When no people are detected indoors, and after the humidity value of indoor air is between 35% and 70% and kept for 10min, a control module in the air conditioner controls the air deflector 7 to the air deflector position 5 in fig. 2, the wind speed is switched to high wind, after the air speed lasts for 1min, the original operation mode that the wind speed is low wind or breeze is recovered, and the air deflector 7 is positioned at the air deflector position 1 or the air deflector position 2.
In step S530, when the humidity value of the indoor air is greater than the second threshold value, the air conditioner is controlled to enter a second anti-condensation mode.
Specifically, when the humidity value of the indoor air is greater than 70% and lasts for 10min, it is indicated that the humidity of the indoor air is high and the possibility of condensation is high. At this time, the control module in the air conditioner directly controls the air deflector 7 to the air deflector position 5 in fig. 2, the wind speed is switched to high wind, after the air deflector lasts for 1min, the original operation mode that the wind speed is low wind or breeze is restored, and the air deflector 7 is positioned at the air deflector position 1 or the air deflector position 2. And after the interval of 10min, continuously controlling the position of the air deflector 7 to the position 5 of the air deflector in fig. 2, and simultaneously switching the air intensity to be high air for 1min and recovering. After each second anti-condensation mode is finished, the air conditioner controls the humidity sensing device in the air conditioner to detect the humidity value of the indoor air, and when the humidity value of the indoor air is still more than 70%, the operation is repeated until the humidity value of the indoor air is no longer in the range of more than 70%.
In a preferred technical scheme, humidity induction device in the air conditioner can real-time response indoor air humidity value to according to indoor air's humidity value control air conditioner real-time entry corresponding mode, on guaranteeing user experience's basis, effectively prevent that the condensation from producing.
In a more preferred embodiment, the air conditioner may detect the humidity value of the indoor air at every interval of 0.25 s. When the humidity value of the indoor air exceeds the current range in the running process of the air conditioner in a certain step, the air conditioner can jump to enter the corresponding step in real time.
In one possible implementation manner, when the air conditioner is in step S520, continuously detecting the humidity value of the indoor air in the first time and the third time, and when the humidity value of the indoor air is less than 35%, jumping to step S510 in real time; when the humidity value of the indoor air is greater than 70%, the real-time process goes to step S530. Similarly, the air conditioner detects the humidity value of the indoor air in real time when the air conditioner operates in step S510, jumps to step S520 in real time when the humidity value of the indoor air is within 35% to 70%, and jumps to step S530 in real time when the humidity value of the indoor air is greater than 70%. When the air conditioner runs the step S530, continuously detecting the humidity value of the indoor air in the third time, and when the humidity value of the indoor air is less than 35%, jumping to the step S510 in real time; when the humidity value of the indoor air is within 35% to 70%, the process jumps to step S520 in real time.
In addition, the invention also provides an air conditioner, which is suitable for executing any one of the anti-condensation control methods for the air conditioner.
