The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The present embodiment proposes a sterilization control method for an air conditioner with sterilization function, such as the flowchart in fig. 1, when the following three sterilization conditions are simultaneously satisfied, the sterilization is started;
the temperature of the indoor evaporator is less than or equal to a preset temperature T;
the indoor fan operates normally;
the opening state of the air deflector is normal;
when any one of the above three sterilization conditions is not satisfied, the sterilization function is not activated.
The sterilization module in the embodiment is installed at a position where people can not directly touch the sterilization module, and a wind circulation place is needed so as to perform wider air sterilization, so that the installation position of the sterilization module is close to the evaporator, and the temperature of the evaporator has certain influence on the service life of the sterilization module. The preset temperature T represents a critical temperature set by a program and allowed to start the sterilization module, and the value of the critical temperature can be determined according to experiments, for example, the preset temperature T is 58 ℃. This embodiment is to current air conditioner that disinfects, sets for the state through sensor collection relevant environmental parameter and operation on combining the air conditioner and come intelligence start-stop sterilization module to this avoids because the module that disinfects near high temperature leads to the damage such as module accelerated ageing that disinfects. The fan is prevented from not being started or running smoothly, air is not circulated and is started for sterilization, the effect of sterilizing indoor air cannot be achieved, loss is caused to the sterilization module, and the service life is prolonged on the premise that the sterilization effect is guaranteed.
In this embodiment, the determination sequence of the three sterilization conditions that need to be satisfied for starting the sterilization function may not be limited, as long as the three sterilization conditions are satisfied at the same time, i.e., the sterilization is started, and if one of the three sterilization conditions is not satisfied, the sterilization is not started. The timing for judging whether the sterilization is started in the embodiment can be judged before the sterilization function is started for the first time after the air conditioner is started, if the start condition is met, the sterilization is started, and if the start condition is not met, the sterilization is not started. Or judging in the starting process of the sterilization function, if the starting condition is met, continuing to start sterilization, and if the starting condition is not met, stopping sterilization.
Further optionally, whether to start sterilization is judged according to the following steps:
whether to start sterilization is judged according to the following steps:
s1, acquiring the temperature of the indoor evaporator, and entering S2 when the temperature of the indoor evaporator is less than or equal to a preset temperature T;
s2, acquiring the running state of the indoor fan, and entering S3 when the indoor fan is judged to run normally;
s3, acquiring the opening state of the wind deflector, and starting sterilization when the opening state of the wind deflector is judged to be normal;
when the condition defined by any one of the steps S1, S2 and S3 is not satisfied, the next step is not proceeded to.
The present embodiment determines the judgment logic by the influence of each sterilization condition on the service life and the sterilization effect of the sterilization module, and since the evaporator temperature represents the ambient temperature of the sterilization module, the aging of the sterilization module is accelerated when the ambient temperature of the sterilization module is too high, which seriously influences the service life, the evaporator temperature is judged at first. Secondly, when the indoor fan is in an abnormal operation state, air circulation is not smooth, indoor air cannot be sterilized, the indoor fan belongs to invalid work, the sterilization is started under the condition, the sterilization module is still lost, and therefore the judgment condition is set after the temperature of the evaporator is judged. And finally, the influence of the abnormal opening angle of the air deflector on the sterilization module is minimum, when the opening angle of the air deflector is abnormal, the sterilized air cannot be smoothly blown out of the air deflector to influence the sterilization efficiency, but the air deflector still has a certain sterilization effect, so that the influence of the air deflector on the sterilization module is minimum, and the judgment is finally carried out.
Further optionally, the three sterilization conditions are judged according to a user sterilization instruction. For example, a "health function" key may be provided on the air conditioner remote controller, and when the user presses the "health function" key, a health instruction is sent to the air conditioner. The embodiment is just judging indoor evaporimeter temperature, indoor fan running state and aviation baffle open mode under the condition of receiving the instruction of disinfecting, just opens and disinfects when reaching the condition that the function of disinfecting opened, does not receive the instruction of disinfecting or does not reach the condition that the function of disinfecting opened and disinfect to can come intelligent start to disinfect according to user's demand and the running state that combines the air conditioner, the life of the module that disinfects of extension under the prerequisite that satisfies user's demand of disinfecting.
Further optionally, in the process of judging the running state of the indoor fan, the current rotating speed of the fan is obtained, and when the current rotating speed of the fan is larger than or equal to a preset rotating speed k, the fan is judged to run normally. The preset rotating speed k represents a minimum rotating speed value after the indoor fan normally operates, if the value is continuously lower than the minimum rotating speed value, the fan is considered to be abnormal in operation, and the value is different according to different motors, for example, the preset rotating speed k is 300 r/min.
Further optionally, when the current rotating speed of the fan is less than the preset rotating speed k, and when the duration of the fan at the rotating speed is less than or equal to the preset time t, the fan is judged to be normally operated, otherwise, the fan is judged to be abnormally operated. The preset time t represents the maximum duration allowed when the rotating speed of the fan is less than Kr/min, in order to avoid rotating speed fluctuation, if the duration is more than the time t, the fan is considered to be abnormal in operation, and the time is set according to the characteristics of the fan, for example, the preset time t is 15 s.
This embodiment avoids the fan to open under the not open or not smooth condition of operation the module of disinfecting but can't play the effect of disinfecting to the indoor air through the detection to fan running state, nevertheless has still caused the loss to the module of disinfecting.
Further optionally, before the current rotating speed of the fan is obtained, the set rotating speed of the fan is also obtained, and when the set rotating speed of the fan is larger than or equal to a preset rotating speed k, the current rotating speed of the fan is obtained; otherwise, judging that the fan operates abnormally, and not acquiring the current rotating speed of the fan. .

s23, judging whether the duration time that the current rotating speed of the fan is less than the preset rotating speed k is longer than the preset time t; if the judgment result is yes, judging that the fan is abnormal in operation; if the judgment result is negative, the fan is judged to be normally operated, and the next step S22 is not carried out.
Further optionally, in the process of judging the opening state of the air deflector, the set opening angle of the air deflector and the current opening angle of the air deflector are obtained, and when the following two conditions are met, the normal state of the air deflector is judged:
the set angle of the air deflector is more than or equal to a preset angle theta;
the current opening angle of the air deflector is more than or equal to a preset angle theta;
the preset angle theta represents the minimum opening angle of the air deflector, the program set angle is certainly larger than theta after the air deflector is started, if the actual opening angle is smaller than min degrees, the air deflector is opened abnormally, and the value is set according to the air conditioner structure, for example, the opening angle of the air deflector is set to be 15 degrees. According to the embodiment, the opening angle of the air deflector is detected to avoid unsmooth air circulation and reduction of the sterilization effect caused by the undersize opening angle of the air deflector after the sterilization module is started.
