Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The present invention proposes a control method and system for an air conditioner indoor unit. The rotational speed of the drive motor is determined by the obtained fan rotational speed. , reduce the speed of the drive motor, thereby reducing the noise of the drive motor and the friction noise between the air guide and the airflow, thereby reducing the use noise of the entire air conditioner and improving the user experience. Next, the air conditioner indoor unit control method and system of the present invention will be described in detail.

[0032] The air-conditioning indoor unit includes a housing, a fan, a driving motor, and an air guide; the housing is provided with an air inlet and an air outlet, and an air duct connecting the air inl...

Abstract

The invention discloses a control method and a system of an air conditioner indoor unit. The fan rotating speed is acquired, the rotating speed of a driving motor is determined according to the rotating speed of a fan; a rotating speed control signal is generated according to the rotating speed of the driving motor, and used for controlling the driving motor to rotate; the rotating speed of the driving motor is reduced along with the increase of the rotating speed of the fan, so that the use noise of a whole air conditioner is reduced; and the problem that the noise of the air conditioner is large when the fan of an existing air conditioner indoor unit operates at high rotating speed is solved, and the use experience of the user is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner indoor unit control method and system. Background technique [0002] At present, many models of air conditioners require high-speed operation of the internal fan, or the diameter of the internal cross-flow fan is increased due to the pursuit of rapid cooling and rapid heating, or special occasions (ordinary restaurants, etc.) that require high-speed and powerful air volume. Consumers in these occasions do not have particularly high requirements for noise effects, but as an important household appliance that mainly improves sleep quality and quality of life, air conditioners have very strict noise requirements in bedrooms, high-end hotels and other occasions that require quietness. [0003] The air guide is driven by a drive motor, and the swing speed of the air guide is controllable, but the swing is rigid. After setting the parameters, it ...
