Abstract

The present invention is applicable to the field of home appliance control, and provides a method for controlling the lifting door of an air conditioner, a microprocessor and a device for lifting the door of the air conditioner. Stroke, preset the control parameters of the stepper motor in the three stages of start, run and stop, the control parameters include the motor drive mode, single-beat pulse frequency and the number of pulses required; obtain the control mode of the lift door, including the rising or descending; calling corresponding control parameters according to the control mode, and correspondingly outputting motor control commands at each stage to control the ascending or descending of the lifting door. In the technical solution of the present invention, the output torque and rotational speed of the stepping motor can be flexibly adjusted through the preset control parameters, so that the lifting door can run smoothly, and the noise of starting, running and stopping can be effectively improved. On the other hand, the stepping motor has high control precision and can The auxiliary detection part of the limit switch is omitted, which saves the cost.

Description

technical field [0001] The invention belongs to the field of home appliance control, and in particular relates to a control method for an air conditioner lift door, a microprocessor and an air conditioner lift door device. Background technique [0002] Traditional air conditioner lift doors are driven by synchronous motors, and relays are used to control the energization sequence of the synchronous motors to achieve forward and reverse rotation of the motors. At the same time, photoelectric switches are matched to realize limit and position judgment detection, and complete the control of lift door lift movements. For example, a Chinese patent (Patent No. CN101413708B) discloses a sliding door control device and method, which requires a limit switch to assist in detecting the operating position of the sliding door, and ensures that the sliding door is completely closed and opened by setting multiple reserved times. [0003] The existing lifting door device of air conditioner ...
