Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] In the prior art, the air conditioner fan motor usually uses a tap motor, and the air volume generated by it is relatively fixed and cannot be adjusted freely. The air volume is inconvenient to control, which is not conducive to further improving user experience. In order to solve the above problems, refer to the figure 1 As shown, the embodiment of the present invention provides a fan PG motor control method, including the following steps:

Abstract

The embodiment of the invention provides a draught fan PG motor control method, a draught fan and an air conditioner and relates to the field of air conditioners. The rotating speed of an air conditioner draught fan motor can be controlled accurately. The method comprises the steps of acquiring the actual rotating speed of the PG motor within a first preset time duration; matching the acquired actual rotating speed with a preset target rotating speed and reducing the conduction angle of the PG motor when the actual rotating speed is greater than the preset target rotating speed; increasing the conduction angle of the PG motor when the actual rotating speed is less than the preset target rotating speed; and keeping the conduction angle of the PG motor unchanged when the actual rotating speed is equal to the preset target rotating speed. The draught fan PG motor control method is used for conducting control over the air conditioner draught fan.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a method for controlling a fan PG motor, a fan and an air conditioner. Background technique [0002] As an indispensable part of modern air conditioners, the fan plays the role of blowing the hot and cold air converted by the air conditioner to the air conditioner user's room. The wind generated by the fan can affect the user's experience of cooling or heating the air conditioner. At present, the tap motor is generally used as the air conditioner fan motor, and its air volume is relatively fixed and cannot be adjusted freely. The air volume is inconvenient to control, which is not conducive to further improving user experience. Contents of the invention [0003] The embodiment of the invention discloses a fan PG motor control method, a fan and an air conditioner, which can accurately control the rotation speed of the air conditioner fan motor, and realize effective control of th...
