Abstract

The invention provides a start control method of a multi-gear motor in an indoor fan of an air conditioner. The start control method of the multi-gear motor in the indoor fan of the air conditioner comprises the following steps that a, when the multi-gear motor in the indoor fan needs to be started at the lowest gear under the control of the air conditioner, a controller of the air conditioner firstly controls the multi-gear motor to operate at a high gear for 0.1-5 seconds, and specifically, the number of gears of the multi-gear motor is three or more; when the number of the gears of the multi-gear motor is three, the controller of the air conditioner firstly controls the multi-gear motor to operate for 0.1-5 seconds at the second gear, and the first gear is the lowest gear; and when the number of the gears of the multi-gear motor is larger than three, the controller of the air conditioner firstly controls the multi-gear motor to operate for 0.1-5 seconds at the third gear, and the first gear is the lowest gear; and b, then the controller of the air conditioner controls the multi-gear motor to be switched to operate at the lowest gear. According to the start control method of the multi-gear motor in the indoor fan of the air conditioner, on the premise that the using comfort of a user is guaranteed, and the situation that normal starting cannot be achieved when the multi-gear motor is started at the lowest gear can be effectively avoided.

Description

technical field [0001] The invention relates to a motor, in particular to a start-up control method for a multi-speed motor in an air-conditioning indoor fan. Background technique [0002] The development of air conditioners pays more and more attention to user comfort experience. The indoor fans of existing air conditioners generally use multi-gear motors with at least three gears. The motor speeds corresponding to each gear are different. In this way, when the air conditioner is running , the controller of the air conditioner can control the speed of the motor by changing the gear of the motor, so as to adjust the air volume and speed of the indoor fan, so that the indoor temperature can change more smoothly, thereby improving the comfort of the user . At present, when the existing air conditioners are started, in most cases, the multi-gear motor in the indoor fan will be started at the lowest gear. When the wind blown by the fan blows, it will cause discomfort, and the ...
