Problems solved by technology
However, the current range hoods, especially the near-suction / side-suction type, have a relatively large smoking area on the panel. Although the air volume of the whole machine is very large, some can reach 17 cubic meters per minute, but the smoking port closest to the oil fume The suction force of the range hood is not the maximum, which causes the range hood to inhale more clean and invalid air

Embodiment Construction
[0022] Below in conjunction with accompanying drawing just use this range hood to further describe the present invention in detail:
[0023] refer to Figure 1 to Figure 6 As shown, the multi-point suction range hood includes a smoking chamber 1, a smoking fan and a control device, and the smoking chamber is divided into at least two mutually isolated smoking chamber units (in this embodiment, 4 smoking chamber units are taken as For example, respectively the first smoking cavity unit 11, the second smoking cavity unit 12, the third smoking cavity unit 13, and the fourth smoking cavity unit 14), each smoking cavity unit is provided with a smoke detection device 9 for changing the smoking cavity The baffle device 18 of the size of the unit outlet, and the baffle electric control device that controls the opening of the corresponding baffle according to the smoke concentration signal detected by each smoke detection device under the control of the control device.

The invention provides a multi-point separated absorbing type range hood. The multi-point separates absorbing type range hood comprises a smoke absorbing chamber, a smoke absorbing fan and a control device, wherein the smoke absorbing chamber is divided into at least two smoke absorbing cavity units which are isolated from each other; each smoke absorbing cavity unit is provided with a smoke detection device, a baffle device for changing the size of an outlet of the smoke absorbing cavity unit as well as a baffle electric control device which is used for controlling the opening degree of the corresponding baffle according to a smoke concentration signal detected by each smoke detection device under the control of the control device. The multi-point separated absorbing type range hood provided by the invention has the beneficial effects that each smoke absorbing cavity unit is provided with an independent baffle device by arranging multiple smoke absorbing cavity units, the corresponding opening degree is set according to lampblack concentration of different parts, the enough negative pressure is provided for a high lampblack concentration part on the premise of low rotating speed of a fan, the noises are effectively lowered, the energy is saved, and the consumption is reduced.
Description
technical field [0001] The invention relates to the field of kitchen appliance control, in particular to a multi-point split-suction range hood and a control method thereof. Background technique [0002] The main performance evaluation indicators of the current range hood are the air volume, that is, the ability to remove oil fumes, and the other is the working noise. Often this is a pair of contradictions. Range hoods with large air volume increase the air volume and suction by increasing the speed of the main motor to drive the volute impeller, but at the same time bring a lot of noise; while range hoods with relatively low noise on the market have air volume and Suction is often not great. [0003] On the other hand, during the cooking process in the family, one side of the stove is often working, which produces relatively large oil fume, while the other side produces little or no oil fume. However, the current range hoods, especially the near-suction / side-suction type,...
