Problems solved by technology

However, for other brands of range hoods, the values ​​of fan current and lighting current are relatively close, and misjudgment may occur in practical applications, resulting in the air valve controller not being able to accurately control the opening / closing of the power distribution valve. Abnormal, affecting the smoke exhaust effect in the user's home

Embodiment 1

[0042] In step S102, the current signal and the duct wind pressure signal of the fan of the range hood are obtained.

[0045] Controlling the power distribution valve at least includes: controlling the power distribution valve to open, controlling the power distribution valve to open and close, and

[0046] Step S106, the gear information is reported to the host, to adjust the frequency of the host fan of the host.

Embodiment 2

[0051] Step S202, obtaining the current signal of the fan of the range hood collected by the current detection circuit.

[0054] Step S204, obtaining the wind pressure signal of the pipe of the fan of the range hood collected by the wind pressure detection circuit.

[0055] The current signal of the fan of the range hood can be detected by the wind pressure detection circuit. For example: the wind pressure detection circuit contains

[0061] (2) If the current signal is 0, it is determined that the state of the fan is a shutdown state; the power distribution valve can be controlled to close.

[0069] In step S208, the gear position information is reported to the host to adjust the frequency of the host fan of the host.

Embodiment 3

[0077] In step S504, the fan frequency of the host fan is adjusted based on a plurality of gear positions.

Abstract

The invention provides a control method and device for a central range hood system and the central range hood system. Wherein, the method is applied to the air valve controller of the central range hood system; the air valve controller is set in the power distribution valve of the range hood, and the air valve controller is connected to the host computer through communication; the method includes: obtaining the fan of the range hood The current signal and the pipeline wind pressure signal; determine the gear information of the fan based on the current signal and the pipeline wind pressure signal, and control the power distribution valve; report the gear information to the host to adjust the frequency of the host fan of the host. This method collects the current signal of the range hood fan and the pipeline wind pressure signal, controls the power distribution valve through the current signal and the pipeline wind pressure signal, calculates the gear position information of the range hood and adjusts the frequency of the main engine fan, and can accurately identify the range hood The state and gear position of the machine can precisely adjust the air volume of the main engine fan, and the effect of oil fume emission is better.

Description

Central range hood system control method, device and central range hood system technical field The present invention relates to the technical field of electrical appliances, especially relate to a kind of central range hood system control method, device and Central range hood system. Background technique [0002] The central range hood generally adjusts the air volume of the fan through frequency conversion, and the host is turned on according to the range hood in the user's home. The number of fans adjusts the fan frequency to realize the variable frequency adjustment of the air volume, and the air valve controller is based on the power distribution valve of other users at home. The switch state adjusts the opening angle of the power distribution valve to achieve a balanced air volume. Generally speaking, there is a current detection circuit on the air valve controller, which can detect the current signal of the range hood, thereby identifying the Check whether the ...
