Embodiment 1

[0019] Such as figure 1 As shown, the present invention is a method for controlling the backflow of the range hood, which is to set the automatic backflow function on the control panel of the range hood, and set two working modes of intelligent scene and custom scene for selection, control The motor of the range hood runs in low-speed mode; in this embodiment, the smart scene is 3 fixed time periods preset by the control panel 8, morning: 7:00-8:00, noon: 11:00-12:00 ;Evening: 6:00-8:00, the anti-backflow mode is turned on 7 days a week;

[0020] The custom scene is 3 time periods that can be set by yourself. Each time period can be set up to 120 minutes. The time period T1-T2 for anti-backflow is set by customizing. When T1<T<T2, the hood is automatically turned on. Execute the active defense mode to prevent the backflow of oil fume from the public flue during the peak cooking period, and you can choose whether to turn it on or not every day. In the anti-backflow mode, the ...

Embodiment 2

[0023] Such as figure 2 and image 3 As shown, in this embodiment, a check valve 4 is also provided in the smoke exhaust passage, and the check valve 4 is provided with a rotating fan blade 5, and a micro generator 6 is connected to the center of the rotating blade, and the micro generator is connected to the main controller 8 , when the lampblack pours backwards, the rotating fan blade 5 will reverse, and the micro-generator will generate an induced current, which will be fed back to the main controller. The road oil fume is intercepted outside to achieve the purpose of anti-backflow. Check valve 4 comprises check valve main body 4-1 and the anti-backwash blade 4-2 that is arranged in it, the fixed support 4-3 that is fixed on the air outlet place of check valve main body, and rotating vane is passed micro-generator and fixed The brackets are connected.

[0024] Compared with the prior art, the present invention can automatically start the motor of the range hood at a low...

Abstract

The invention discloses an anti-backward-flowing control method for a range hood. The anti-backward-flowing control method is characterized by comprising the following steps: an automatic anti-backward-flowing function is set in a control panel of the range hood, two working modes of intelligent scenes and custom scenes are set for selection, and a motor of the range hood is controlled to run in a low-speed mode; the intelligent scenes are a plurality of fixed time periods preset in the control panel, so that an anti-backward-flowing mode is turned on when the time periods are achieved every day; and the custom scenes are a plurality of time periods capable of being set by a user, the maximum value of each time period is set to 120min, a time period of turn-on of the anti-backward-flowing mode is set to T1-T2 in a custom manner, and the range hood is automatically turned on to execute an active defense mode when T is greater than T1 and less than T2. A controller in the invention is capable of automatically realizing the anti-backward-flowing function, so that the motor runs in a low-speed and silent mode to intercept lampblack in a shared flue outside, thereby realizing an anti-backward-flowing purpose.

Description

technical field [0001] The invention relates to the technical field of range hoods, and more specifically relates to a method for controlling backflow of range hoods. Background technique [0002] When the smoke exhaust pipe of the hood is installed in the public flue, when the hood is not started, the oil fume is often poured back, and the hood needs to have the function of reverse flow. Most of the range hoods on the market do not have the function of automatic backflow; for range hoods with the function of backflow, it is necessary to manually turn on the existing high speed, medium speed or low speed to achieve the purpose of backflow; the backflow lasts for a long time and the noise is loud , High energy consumption. Contents of the invention [0003] The object of the present invention is to provide a method for controlling backflow of range hoods that is not only simple and convenient to operate, but also can intercept oil fumes from public flues in order to solve ...
