Technical Field
The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner and the air conditioner.
Background
With the high-speed development of household appliance technology, the design concept of comfort of air conditioning products has been gradually improved, and end users have higher demands on the comfort fresh air function of the air conditioner, and in order to avoid the problems of poor user experience and even complaints caused by condensation dripping while the fresh air function is achieved by the existing products, various anti-condensation measures, such as adjusting the angle of an air deflector or controlling the rotation speed change of a fan by detecting the humidity or the temperature of an air outlet, are generally adopted to prevent condensation.
However, when the anti-condensation measures in the related art solve the problem of fresh air condensation, the performance of the whole machine is generally lost (such as reducing the rotation speed and increasing the set temperature), and the effect of poor user perception experience is easily caused (the user suddenly perceives the wind speed or automatically adjusts the air deflector, and the air conditioner is wrongly out of control).
Disclosure of Invention
In order to solve the problem that the air conditioner in the related art is easy to cause poor comfort of a user in using the fresh air function of the air conditioner when the fresh air is condensed, the invention provides a control method of the air conditionerThe control method comprises the following steps: judging whether the air conditioner starts a fresh air function or not; under the condition that the air conditioner starts a fresh air function, an internal machine environment temperature value is obtained and recorded as t n The method comprises the steps of carrying out a first treatment on the surface of the After the first time length of the internal machine environment temperature value is obtained, updating the internal machine environment temperature value, and recording t n ＝t n+1 The method comprises the steps of carrying out a first treatment on the surface of the And controlling the rotating speed of an inner fan of the air conditioner, the angle of an air deflector and the set temperature according to the environmental temperature value of the inner machine, whether a user exists in a target area and whether the air conditioner starts a wind sweeping function, so as to avoid condensation of the inner machine of the air conditioner.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: after the fresh air function of the air conditioner is started, whether the inner machine has condensation risk can be judged according to the inner machine environment temperature value by acquiring the inner machine environment temperature value. After the first time length of the internal machine environment temperature value is obtained, updating the internal machine environment temperature value, and recording t n ＝t n+1 The internal machine environment temperature value obtained after the first time length is used for covering the previous internal machine environment temperature value, so that the situation that the data volume is doubled due to the fact that too many internal machine environment temperature values are stored in a memory can be avoided, the program processing time and the code processing volume are increased, the program processing time is shortened, and the data processing efficiency is improved. The inner fan rotating speed, the air deflector angle and the set temperature of the air conditioner are controlled according to the environmental temperature value of the inner machine, whether a user exists in a target area or not and whether the air conditioner starts a wind sweeping function or not, so that condensation of the inner machine of the air conditioner is avoided, intelligent accurate regulation and control of the air deflector angle and flexible control of the wind speed of the inner fan can be realized, and the use comfort of the user can be improved while the condensation of the inner machine is avoided; and then humanized and comfortable fresh air condensation prevention can be truly realized.
In one example of the present invention, the controlling the rotation speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to the environmental temperature value of the inner machine, whether the target area exists or not, whether the air conditioner starts the wind sweeping function, includes: judging whether the environmental temperature value of the internal machine meets a first preset condition or not; if yes, controlling the rotating speed of an inner fan of the air conditioner according to whether a user exists in the target area and whether the air conditioner starts a wind sweeping functionThe angle and the set temperature of the air deflector; wherein the first preset condition includes: t is t n ≤T Condensation water ；t n Is the environmental temperature value of the internal machine; t (T) Condensation water Is a preset dew point temperature.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: it is understood that condensation forms when the air temperature is reduced to the dew point temperature. If t n ≤T Condensation water The current internal machine environment temperature is lower, the current internal machine environment temperature meets the dew point temperature condition, condensed water is easy to generate in the internal machine, and corresponding measures are needed to avoid the condensation of the internal machine of the air conditioner. The method comprises the steps of controlling the rotation speed of the inner fan of the air conditioner, the angle of the air deflector and the set temperature according to whether a user exists in a target area or not and whether the air conditioner starts the air sweeping function or not, selecting corresponding condensation-preventing measures from the rotation speed of the inner fan of the air conditioner, the angle of the air deflector and the set temperature according to whether the user exists in the target area or not, and rapidly eliminating condensed water and avoiding condensation under the condition of not affecting the use experience of the user.
In one example of the present invention, before determining whether the internal unit environmental temperature value meets the first preset condition, the control method of the air conditioner further includes: judgment of t n ＞t n+1 Whether or not to establish; if so, judging whether the environment temperature value of the internal machine meets a first preset condition; if not, circularly executing the steps of updating the internal machine environment temperature value after the first time length of acquiring the internal machine environment temperature value is obtained, and recording t n ＝t n+1 And (3) operating.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: it can be understood that the temperature in the refrigeration mode is a decreasing trend, and if the abnormal temperature rises, it is indicated that there may be a sudden temperature change caused by factors such as fresh air intervention, entry or movement of a person. Considering that such factors reduce the risk of condensation, the advanced process eliminates the abnormal temperature, i.e. advances the next data, before determining whether the internal machine ambient temperature value meets the first preset condition.
In one example of the present invention, the controlling the rotation speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to whether the user exists in the target area and whether the air conditioner starts the wind sweeping function comprises: starting a spatial human body recognition device, and detecting whether a user exists in a target area; if the user exists in the target area, controlling the rotating speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to whether the air conditioner starts the wind sweeping function or not.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: by starting the spatial human body recognition device, whether a user exists in the target area is detected, and different anti-condensation measures can be selected according to whether the user exists in the target area, so that misunderstanding of the user caused by air deflector or wind speed change is avoided.
In one example of the present invention, if a user exists in the target area, controlling the rotation speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to whether the air conditioner is started to perform the wind sweeping function includes: if the air conditioner starts the wind sweeping function, the rotating speed of the inner fan is increased, the angle of the air deflector is controlled to be the current set angle of the air deflector, and the set temperature is controlled to be the current set temperature; if the air conditioner does not start the wind sweeping function, the set temperature is increased, the rotating speed of the inner fan is controlled to be the rotating speed of the inner fan, and the angle of the air deflector is controlled to be the angle of the air deflector.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: it can be understood that when a user exists in the target area, the user is very easy to feel the difference change of the air outlet of the air conditioner, and the air deflector or the wind speed change is easier to cause misunderstanding of the user. Because the wind sweeping function can be accompanied with wind direction change and wind speed change, discomfort caused by the automatic regulation of the wind speed by a program can be reduced when the wind sweeping function of the air conditioner is started, the air conditioner is suitable for avoiding condensation by regulating the rotation speed of the inner fan under the condition that the wind sweeping function of the air conditioner is started, and therefore the air conditioner is controlled to increase the rotation speed of the inner fan, control the angle of the air deflector to be the current set angle of the air deflector and control the set temperature to be the current set temperature, and the condensation is quickly eliminated by increasing the rotation speed of the inner fan to avoid condensation. Under the condition that the air conditioner is not opened with the wind sweeping function, users are easy to misunderstand no matter the rotating speed of the inner fan is regulated or the angle of the air deflector is changed, so that a mode of temperature regulation is adopted, the temperature of the inner coil of the evaporator is changed by controlling the circulation of the refrigerant by improving the set temperature, the temperature of the evaporator is indirectly regulated, and condensation of the inner machine is avoided.
In one example of the present invention, the control method of the air conditioner further includes: if no user exists in the target area, increasing the rotating speed of the inner fan, increasing the angle of the air deflector and controlling the set temperature to be the current set temperature.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: under the condition that no user exists in the target area, the air deflector or the wind speed change can not cause misunderstanding of the user, so that the user experience is poor, and condensed water is quickly eliminated and condensation is avoided by a mode of combining increasing the rotating speed of the inner fan with increasing the angle of the air deflector.
In one example of the present invention, the increased value of the inner blower rotational speed in the absence of a user within the target area is greater than the increased value of the inner blower rotational speed in the presence of a user within the target area.
Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: when no user exists in the target area, condensation can be reduced with maximum efficiency; when a user exists in the target area, the discomfort caused by the automatic regulation of the wind speed by the program can be reduced when the wind sweeping function of the air conditioner is started, but the discomfort cannot be completely eliminated, so that the increase value of the rotating speed of the inner fan when no user exists in the target area is larger than that when the user exists in the target area.
The embodiment of the invention provides an air conditioner, which realizes the control method of any air conditioner as described above, and comprises the following steps: the judging module is used for judging whether the air conditioner starts a fresh air function or not; the acquisition module is used for starting fresh air function in the air conditionerUnder the condition of (1), the environmental temperature value of the internal machine is obtained and is recorded as t n The method comprises the steps of carrying out a first treatment on the surface of the The updating module is used for updating the internal machine environment temperature value after the first time length of the internal machine environment temperature value is obtained, and recording t n ＝t n+1 The method comprises the steps of carrying out a first treatment on the surface of the And the control module is used for controlling the rotating speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to the environmental temperature value of the inner machine, the existence of a user in a target area and the starting of the wind sweeping function of the air conditioner so as to avoid condensation of the inner machine of the air conditioner.

It can be understood that after the fresh air function of the air conditioner is started, whether the inner machine has the risk of condensation can be judged according to the inner machine environment temperature value by acquiring the inner machine environment temperature value. After the first time length of the internal machine environment temperature value is obtained, updating the internal machine environment temperature value, and recording t n ＝t n+1 The internal machine environment temperature value obtained after the first time length is used for covering the previous internal machine environment temperature value, so that the situation that the data volume is doubled due to the fact that too many internal machine environment temperature values are stored in a memory can be avoided, the program processing time and the code processing volume are increased, the program processing time is shortened, and the data processing efficiency is improved. The inner fan rotating speed, the air deflector angle and the set temperature of the air conditioner are controlled according to the environmental temperature value of the inner machine, whether a user exists in a target area or not and whether the air conditioner starts a wind sweeping function or not, so that condensation of the inner machine of the air conditioner is avoided, intelligent accurate regulation and control of the air deflector angle and flexible control of the wind speed of the inner fan can be realized, and the use comfort of the user can be improved while the condensation of the inner machine is avoided; and then humanized and comfortable fresh air condensation prevention can be truly realized.

T corresponding to air conditioners with different cold capacities Condensation water Different, the experimental effect of the actual model is based.
It is understood that condensation forms when the air temperature is reduced to the dew point temperature. If t n ≤t Condensation water The current internal machine environment temperature is lower, the current internal machine environment temperature meets the dew point temperature condition, condensed water is easy to generate in the internal machine, and corresponding measures are needed to avoid the condensation of the internal machine of the air conditioner. The method comprises the steps of controlling the rotation speed of the inner fan of the air conditioner, the angle of the air deflector and the set temperature according to whether a user exists in a target area or not and whether the air conditioner starts the air sweeping function or not, selecting corresponding condensation-preventing measures from the rotation speed of the inner fan of the air conditioner, the angle of the air deflector and the set temperature according to whether the user exists in the target area or not, and rapidly eliminating condensed water and avoiding condensation under the condition of not affecting the use experience of the user.
Further, before determining whether the internal machine environment temperature value meets the first preset condition, the control method of the air conditioner further includes: judgment of t n ＞t n+1 Whether or not to establish; if so, judging whether the environment temperature value of the internal machine meets a first preset condition; if not, circularly executing the steps of updating the internal machine environment temperature value after the first time length of acquiring the internal machine environment temperature value is obtained, and recording t n ＝t n+1 And (3) operating.
It can be understood that the temperature in the refrigeration mode is a decreasing trend, and if the abnormal temperature rises, it is indicated that there may be a sudden temperature change caused by factors such as fresh air intervention, entry or movement of a person. Considering that such factors reduce the risk of condensation, the advanced process eliminates the abnormal temperature, i.e. advances the next data, before determining whether the internal machine ambient temperature value meets the first preset condition.
Further, the controlling the rotation speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to whether the user exists in the target area and whether the air conditioner starts the wind sweeping function comprises the following steps: starting a spatial human body recognition device, and detecting whether a user exists in a target area; if the user exists in the target area, controlling the rotating speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to whether the air conditioner starts the wind sweeping function or not. The target area is an area where a user is very easy to feel the variation of the air outlet difference of the air conditioner. For example, the spatial human recognition device may be an infrared light sensor.
It can be understood that by opening the spatial human body recognition device, whether a user exists in the target area is detected, and different anti-condensation measures can be selected according to whether the user exists in the target area, so that misunderstanding of the user caused by air deflector or wind speed change is avoided.
Further, if a user exists in the target area, controlling the rotation speed of the inner fan, the angle of the air deflector and the set temperature of the air conditioner according to whether the air conditioner is started with the wind sweeping function comprises: if the air conditioner starts the wind sweeping function, the rotating speed of the inner fan is increased, the angle of the air deflector is controlled to be the current set angle of the air deflector, and the set temperature is controlled to be the current set temperature; if the air conditioner does not start the wind sweeping function, the set temperature is increased, the rotating speed of the inner fan is controlled to be the rotating speed of the inner fan, and the angle of the air deflector is controlled to be the angle of the air deflector. When the air conditioner starts the wind sweeping function, the inner motor drives the air deflector to swing.
It can be understood that when a user exists in the target area, the user is very easy to feel the difference change of the air outlet of the air conditioner, and the air deflector or the wind speed change is easier to cause misunderstanding of the user. Because the wind sweeping function can be accompanied with wind direction change and wind speed change, discomfort caused by the automatic regulation of the wind speed by a program can be reduced when the wind sweeping function of the air conditioner is started, the air conditioner is suitable for avoiding condensation by regulating the rotation speed of the inner fan under the condition that the wind sweeping function of the air conditioner is started, and therefore the air conditioner is controlled to increase the rotation speed of the inner fan, control the angle of the air deflector to be the current set angle of the air deflector and control the set temperature to be the current set temperature, and the condensation is quickly eliminated by increasing the rotation speed of the inner fan to avoid condensation. Under the condition that the air conditioner is not opened with the wind sweeping function, users are easy to misunderstand no matter the rotating speed of the inner fan is regulated or the angle of the air deflector is changed, so that a mode of temperature regulation is adopted, the temperature of the inner coil of the evaporator is changed by controlling the circulation of the refrigerant by improving the set temperature, the temperature of the evaporator is indirectly regulated, and condensation of the inner machine is avoided.
Further, the control method of the air conditioner further comprises the following steps: if no user exists in the target area, increasing the rotating speed of the inner fan, increasing the angle of the air deflector and controlling the set temperature to be the current set temperature.
It can be understood that under the condition that no user exists in the target area, the air deflector or the wind speed change can not cause misunderstanding of the user, so that the user experience is poor, and condensate water at the inner lower wall of the air guide structure is quickly evaporated by a mode of combining increasing the rotating speed of the inner fan with increasing the angle of the air deflector (the condensate water at the upper wall of the air guide structure generally does not drop along the structure downstream), so that the condensate water is avoided. The purpose of adjusting the angle of the air deflector is to quickly evaporate and take away the condensation on the inner lower wall of the air guiding structure.
Further, the increase value of the rotational speed of the inner fan in the case that no user exists in the target area is larger than the increase value of the rotational speed of the inner fan in the case that the user exists in the target area.
It will be appreciated that condensation can be reduced with maximum efficiency when no user is present in the target area; when a user exists in the target area, the discomfort caused by the automatic regulation of the wind speed by the program can be reduced when the wind sweeping function of the air conditioner is started, but the discomfort cannot be completely eliminated, so that the increase value of the rotating speed of the inner fan when no user exists in the target area is larger than that when the user exists in the target area.
In one embodiment, if t n ≤t Condensation water If the current internal machine environment temperature meets the dew point temperature condition, the internal machine is easy to generate condensed water, so the controller CPU controls the opening of the infrared light sensor to detect whether the target area is usefulThe user exists. And under the condition that a user exists in the target area, further judging whether the air conditioner starts a wind sweeping function.
If the target area has a user and the air conditioner starts the wind sweeping function, setting the rotating speed of the inner fan as V 1 (V 1 >1.3*V Setting up ，V Setting up The current set wind speed for the air conditioner), and the angle of the air deflector is set to be theta 1 (θ 1 ＝θ Setting up ，θ Setting up Currently set air deflector angle for air conditioner), set temperature to phi 1 (Φ 1 ＝Φ Setting up ，Φ Setting up For the current set temperature).
If the target area has a user and the air conditioner does not start the wind sweeping function, setting the rotating speed of the inner fan as V 2 (V 2 ＝V Setting up ，V Setting up The current set wind speed for the air conditioner), and the angle of the air deflector is set to be theta 2 (θ 2 ＝θ Setting up ，θ Setting up Currently set air deflector angle for air conditioner), set temperature to phi 2 (Φ 2 ＝Φ Setting up +1℃，Φ Setting up For the current set temperature). Wherein phi is 2 The value is only used for CPU processing judgment and actually displaying the set temperature or phi Is provided with And (5) setting.
If no user exists in the target area, setting the rotating speed of the inner fan to be V 3 (V 3 >1.5*V Setting up ，V Setting up The current set wind speed for the air conditioner), and the angle of the air deflector is set to be theta 3 (θ 3 ＝θ Setting up +5°，θ Setting up Currently set air deflector angle for air conditioner), set temperature to phi 3 (Φ 3 ＝Φ Setting up ，Φ Setting up For the current set temperature). The definition of 5 ° is only illustrated, and the angles are not particularly limited due to different structural limitations, so that the purpose is to illustrate, in addition, the purpose is to realize efficient condensation processing, the change of the wind sweeping angle is illustrated at the position of whether the wind sweeping function is started, and the description is not needed temporarily, and the implementation does not need to consider internal mechanism heating or refrigeration.
