Definitions

  • the present invention relates to the technical field of air conditioner, and in particular, to a method and a device for rotating an air guide plate to a preset position, and an air conditioner.
  • an air conditioner can be made more intelligent, and as a user has a higher requirement on comfort of an air conditioner, the air conditioner rotates to different positions by using different operation modes (refrigeration, heating, etc.) air guide plate, and the position of the air guide plate determines an air supply direction of the air conditioner. Adopting different supply directions in different operation modes can improve the user experience.
  • different operation modes refrigeration, heating, etc.
  • the air scanning angle of the air guide plate is controlled by judging the air conditioner operation mode, and the air guided through the air guide plate flows in a direction of more than horizontal when the upper scanning mode is the lower scanning mode.
  • the wind guided through the air guide plate is caused to flow in a direction less than or equal to the horizontal direction, and when the wind scanning mode is the full-length wind scanning mode, the wind guided through the air guide plate is caused to flow in a direction less than or equal to the horizontal direction and greater than or equal to the horizontal direction.
  • the sweeping operation can be made more reasonable and refined, and various demands of the user can be satisfied.
  • the air guide plate drives the air guide plate to rotate via the motor, and during the rotation of the air guide plate, a weight of the air guide plate and/or a gap between the transmission gears, the air guide plate may generate a position jump, i.e., a virtual position of the air guide plate, so that the rotation angle of the air guide plate cannot be accurately positioned, and when the air guide plate is guided at a preset position, the angle deviates, resulting in an inaccurate wind outlet direction.
  • a position jump i.e., a virtual position of the air guide plate
  • EP3 112 771 A1 discloses a a reset mechanism for electric actuators in heating, ventilating and air conditioning systems.
  • the technical problem to be solved by the present invention is to position the rotation angle of the air guide plate more accurately.
  • the present invention provides acquiring a first angle between a preset position and a first limiting position and a second angle between a second limiting position and the preset position, wherein the first limiting position and the second limiting position are two limiting positions of the air guide plate rotating upward and downward; judging whether the first angle is less than the second angle; when the first angle is less than the second angle, controlling the air guide plate rotates to the first limiting position; controlling the air guide plate to rotate in an opposite direction to the preset position.
  • the invention further includes when the first angle is greater than the second angle, controlling the air guide plate rotates to the second limiting position.
  • the method includes: compensating for an angle of a reverse rotation of the air guide plate.
