t300: when the air is detected to be at a second preset level, controlling the rotating speed of the fan to be a second rotating speed; so, can make the motor of fan work according to the second rotational speed through the motor of controller control fan, so can reduce the rotational speed of fan motor, reduce the amount of wind of new fan, slow down the speed of trading the new trend.
T400: the driving surface cover moves a second preset distance relative to the air outlet end of the fresh air machine shell along the direction close to the air outlet end of the fresh air machine shell. When the air quality sensor detects that the air is at the second preset level, the air quality sensor sends a quality level signal of the indoor air to the controller, the controller drives the driving mechanism according to the quality level signal of the indoor air, so that the driving mechanism drives the face cover to move along the direction close to the air outlet end of the fresh air machine shell, the distance between the face cover and the air outlet end of the fresh air machine shell is reduced, the air volume of the fresh air machine can be reduced, the power consumption of the fresh air machine is reduced, and the fresh air machine can run quietly.
on the basis of the above embodiment, the step that the air-out end of the relative new fan casing of drive face lid moves the second preset distance along the direction that is close to the air-out end of new fan casing still includes after:
T500: and when the indoor object to be detected is not detected, the fresh air fan is turned off. So, whether accessible infrared monitor monitoring is indoor has the determinand, when not detecting indoor when waiting to detect the thing, can close new fan through the controller, so realize energy-conserving purpose. Specifically, the object to be detected may be a human or an animal. In this embodiment, the object to be detected is a person, and thus, when no person is detected indoors, the fresh air fan is turned off, and the purpose of energy conservation is achieved.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
