Air guiding door power-on reset control method and device and air conditioner

Abstract

The invention provides an air guiding door power-on reset control method and device and an air conditioner. The control method comprises the steps that displacement parameters of an air guiding door within the preset time duration are obtained; the opening and closing state of the air guiding door is judged according to the displacement parameters; and when the air guiding door is in a closed state, the air guiding door is controlled to conduct first-angle resetting. Accordingly, the closing state of the air guiding door is judged, and if the air guiding door is in the closed state, the resetangle is set as the first angle instead of setting of the reset angle as the sum of the maximum aperture and the interference angle of the air conditioner air guiding door. Accordingly, the closing and jamming state time of the air guiding door can be very short, so that the problems that due to closing and jamming, an air guiding door is stressed and deforms, the service life of an air guiding motor is shortened, and reliability of the air guiding motor is lowered are solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method and device for power-on reset of an air guide door and an air conditioner. Background technique [0002] In order to ensure that the air guide door is in a reliable closed state when the air conditioner is turned off, and the air guide angle is accurate when the air conditioner is turned on, the current air conditioner method is to reset the air guide door when the power is turned on for the first time. The reset angle is generally the air conditioner guide. The sum of the maximum opening of the damper and the interference angle. [0003] However, in some cases, the air-conditioning air guide door will be in the closed state. If the air conditioner is powered off and then powered on at this time, the air guide door will be closed and stuck for a long time during the reset process. At this time, the air guide motor will be in a locked-rotor state....

AI Technical Summary

Problems solved by technology

[0003] However, in some cases, the air-conditioning air guide door will be in the closed state. If the air conditioner is powered off and then powered on, the air guide door will be closed and stuck for a long time during the reset process. At this time, the air guide motor will be locked. Heat generation and out-of-step problems will occur, which will affect the life of the motor and reduce reliability; and the air guide door is easily deformed by force, which affects the appearance
