Hand-clamping-prevention air guide plate motion mechanism and air conditioner

Abstract

The invention relates to a hand-clamping-prevention air guide plate motion mechanism. The hand-clamping-prevention air guide plate motion mechanism comprises a drive motor, a controller in circuit connection with the drive motor and controlling the drive motor to work, a transmission device which is connected with the power output end of the drive motor and can drive an opening and closing door to rotate within the preset angle, a magnetic disc which is mounted on the transmission device or mounted at the power output end of the drive motor, can rotate along with rotation of the power output end of the drive motor and can generate a changing magnetic field according to changes of the rotating speed and a circuit board which is fixedly mounted on a fixing component which is arranged in advance and connected with the controller; according to the motion mechanism, the driven opening and closing door can stop or return by itself after the hand or other foreign matter enters by mistake, the hand-clamping-prevention function is achieved, and meanwhile, a device is protected against damage; the invention further provides an air conditioner with the motion mechanism.

Description

technical field [0001] The invention relates to the field of daily life and the technical field of air conditioning, in particular to a movement mechanism of a wind deflector capable of preventing hands from being pinched and an air conditioner with the mechanism. Background technique [0002] In the field of air conditioning, generally air conditioners are equipped with air deflectors, and are generally driven by motors to realize air deflections. For the sake of aesthetics, it is necessary to ensure that the gap is minimized after the air deflector is closed, so that the movement mechanism driving the air deflector needs to have a relatively large torque. However, after increasing the torque of the air deflector movement mechanism, the risk is also increased. If the air deflector accidentally stretches a hand into the front of the air deflector when the door is closed, the hand will be pinched. In addition, even if it is not the wrong entry of human hands, if other foreig...

AI Technical Summary

Problems solved by technology

However, after increasing the torque of the air deflector movement mechanism, the risk is also increased. If the air deflector accidentally extends the hand into the front of the air deflector when the door is closed, the hand will be pinched.

In addition, even if it is not the wrong entry of human hands, if other foreign matter enters, due to the preset stroke requirements in the air deflector program, the motor will always drive the movement of the air deflector movement mechanism to reach the preset position, and due to the obstruction of foreign objects, If the wind deflector cannot move in place but continues to run, it will damage the drive motor or other components
