Problems solved by technology

This has led to the fact that in most cases, one side of the burner is working and the other side is not working, or the amount of oil fume is very small when working, and half of the exhaust air volume of the range hood sucks in clean and invalid air, which seriously wastes the hood itself. Not only wastes energy, but also causes the disadvantage of high noise, which leads to poor user experience

Embodiment 1

[0032] Embodiment 1 of the present invention provides a range hood with adjustable air intake area, such as figure 1 and 2 As shown, it includes a box body 1, a smoke collection hood 2, an oil screen structure 3, a fan 4, a sensor 5 and a controller. The air inlet and the right air inlet, the left air inlet and the right air inlet are all equipped with an oil grid structure 3, the fan 4 and the controller are both installed in the box body 1, the sensor 5 is installed on the oil grid structure 3, and the controller is respectively connected to the oil grid The structure 3 is connected to the sensor 5, and is used to adjust the air intake area of ​​the oil net structure 3 according to the concentration of oil smoke collected by the sensor 5.

[0033] The oil net structure 3 includes at least two layers of oil nets arranged inside and outside, at least two layers of oil nets are provided with relative air inlets, and the oil nets located in the inner layer are rotated to change...

Embodiment 2

[0049] Embodiment 2 of the present invention provides a control method for a range hood, which is applied to the range hood with adjustable air intake area as described in Embodiment 1, and its control flow chart is as follows Figure 10 As shown, the range hood starts to operate with the oil net structure fully open; the sensor detects the concentration of the oil fume at the left air inlet and the right air inlet of the range hood in real time; the controller collects the concentration of the oil fume at any air inlet according to the sensor The concentration adjusts the air inlet area of ​​the oil net structure at the air inlet.

[0050] Wherein, the controller adjusts the air intake area of ​​the oil net structure at the air inlet according to the concentration of oil fume collected by the sensor at any air inlet, specifically: the controller determines the concentration of oil fume at any air inlet according to the sensor. Whether oil fume is generated at the air inlet, i...

Abstract

The invention discloses an extractor hood adjustable in air inlet area and a control method thereof. The extractor hood adjustable in air inlet area comprises a box, an exhaust fume collecting hood, oil net structures, an air fan, sensors and a controller, wherein the exhaust fume collecting hood is arranged below the box, a left air inlet and a right air inlet are formed in the exhaust fume collecting hood, the oil net structures are respectively arranged on the left air inlet and the right air inlet, the air fan and the controller are both arranged in the box, the sensors are arranged on theoil net structures, and the controller is connected with the oil inlet structures and the sensors respectively, and used for adjusting the air inlet area of the oil inlet structures according to oilyfume concentrations collected by the sensors. Accordingly, by automatically identifying an oily fume generation area and the generation amount of oily fume, the controller of the oily fume intelligently adjusts opening status of the left and the right air inlet, initiatively adjusts the opening area direction of the air inlets so as to enable the opening area of the air inlets to face the direction towards the oily fume generation area, and simultaneously adjusts running speed of the air fan of the extractor hood, and thereby changes suction force of the extractor hood, and therefore the extractor hood adjustable in air inlet area achieves efficient oily fume suction and extraction, and improves usage experience of a user.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and in particular relates to a range hood with adjustable air intake area and a control method thereof. Background technique [0002] Nowadays, during the cooking process in most families, 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, although the current range hoods have a large air volume, they all indiscriminately and fixedly suck the entire range hood area during use. This has led to the fact that in most cases, one side of the burner is working and the other side is not working, or the amount of oil fume is very small when working, and half of the exhaust air volume of the range hood sucks in clean and invalid air, which seriously wastes the hood itself. Not only wastes energy, but also causes the disadvantage of high noise, which leads to poor user experience. Contents of the invention ...
