Problems solved by technology

[0003] In order to solve at least to a certain extent the problems that when the air outlet of the existing air conditioner is changed, the air flow at the air outlet changes suddenly, the outlet air flow is disordered, aerodynamic noise is generated, and the user experience is deteriorated. This application provides a single centrifugal fan outlet The wind control method, device and controller can effectively alleviate the sudden change of the air flow when the air outlet is changed, make the air flow flow smoothly transition, the noise change smoothly, and improve the user experience

Embodiment 1

[0025] An embodiment of the present invention provides a method for controlling the air output of a single centrifugal fan, such as figure 1 As shown, the air outlet control method of the single centrifugal fan includes:

[0026] S110. Receive an instruction to switch the air outlet state of the single centrifugal fan, where the air outlet state includes an air outlet mode.

[0027] Among them, the air outlet mode of the single centrifugal fan mainly refers to the air outlet state. For example figure 2 As shown in , it is the upper air outlet mode, that is, the windshield of the lower air outlet is closed, and the centrifugal fan only sends air to the outside through the upper air outlet. another example image 3 As shown in , it is the upper and lower air outlet mode, that is, the windshield of the lower air outlet is in the open state, and the centrifugal fan supplies air to the outside through the upper air outlet and the lower air outlet at the same time.

[0028] The...

Embodiment 2

[0063] In order to realize the above method for controlling the air output of a single centrifugal fan, an embodiment of the present invention provides an air output control device for a single centrifugal fan, such as Figure 4 As shown, the device includes:

[0064] The instruction receiving module 410 is used to receive the switching instruction of the air outlet state of the single centrifugal fan, and the air outlet state includes the air outlet mode;

[0065] The speed determination module 420 is used to determine the change speed of the windshield used to adjust the opening of the windshield according to the wind speed of the single centrifugal fan;

[0066] The air outlet control module 430 is configured to adjust the opening of the air deflector according to the determined change speed of the wind deflector, so as to switch to the target air outlet mode.

[0067] In a specific embodiment, the speed determination module 420 can be used to query the preset first wind d...

Abstract

The embodiment of the invention provides a single centrifugal fan air outlet control method and device, a controller and an air conditioning unit, and relates to the field of air conditioners. After aswitching instruction of the air outlet state of a single centrifugal fan is received, the air outlet state comprises an air outlet mode; according to the air outlet speed of the single centrifugal fan, the air baffle change speed adopted for adjusting the opening degree of an air baffle is determined; and the opening degree of the air baffle is adjusted according to the determined air baffle change speed so as to be switched to the target air outlet mode, and switching of the air outlet mode is completed. According to the single centrifugal fan air outlet control method and device, the controller and the air conditioning unit, airflow sudden change during air outlet change can be effectively relieved, air outlet airflow is in stable transition, noise is stably changed, and the user experience is improved.

Description

technical field [0001] The application belongs to the field of air conditioning, and in particular relates to a method and device for controlling the air outlet of a single centrifugal fan, a controller and an air conditioning unit. Background technique [0002] In order to adjust the airflow in the room and solve the cooling and heating comfort problems at the same time, the existing air conditioners usually use multi-fan or single-fan air-conditioning indoor units to realize the upper air outlet, lower air outlet or combined air outlet to solve the problem of air outlet. Problem, but when the air outlet mode is selected and adjusted, the air outlet suddenly changes, resulting in a sudden change in the air flow at the air outlet, resulting in disordered air flow and abnormal sounds such as aerodynamic noise, which deteriorates the user experience. Contents of the invention [0003] In order to solve at least to a certain extent the problems that when the air outlet of the...
