Problems solved by technology

Although the filter device can ensure full contact between the oil fume and the oil filter device, the oil fume can be separated as much as possible, and it can also ensure a certain air intake area, and the loss of air volume and wind pressure is small. The range hood using the filter device has sufficient suction. However, the distance between the orifice filter screen and the wire screen of this filter device cannot be adjusted, that is, the air intake area cannot be adjusted adaptively with the change of the working conditions of the range hood, and the degree of intelligence is low.

Embodiment 1

[0033] Such as Figure 1 to Figure 5 As shown, the intelligent range hood in this embodiment includes main components such as a decorative cover 1, a fan cover 2, a smoke collection cover 3, a fan 4, and an oil filter, wherein the decorative cover 1 and the fan cover 2 constitute the main components of the range hood. The casing, the decorative cover 1 is set outside the fan cover 2, the smoke collecting cover 3 is set under the fan cover 2, the fan 4 is set inside the fan cover 2 and is driven by the fan motor, and the oil filter is set at the inlet of the smoke collecting hood 3. At the tuyere, the above-mentioned structure is the conventional structure of the existing range hood.

[0034] The intelligent range hood of the present embodiment also includes a controller (not shown in the figure), a push rod mechanism 7 and a pressure sensor 8, the signal output end of the pressure sensor 8 is connected with the signal input end of the controller, and the controller The rotati...

Embodiment 2

[0047] Such as Figure 7 to Figure 10 As shown, the range hood of this embodiment forms an installation cavity 9 between the decorative cover 1 and the fan cover 2 , and the push rod mechanism 7 is installed in the installation cavity 9 . The inner oil filter 5 is a fixed oil filter, the outer oil filter 6 is a movable oil filter, the inner oil filter 5 is fixed on the smoke collecting hood 3, and the drive output end of the push rod mechanism 7 protrudes downwards In the installation cavity 9 and connected to the outer oil filter 6, the outer oil filter 6 moves up and down relative to the inner oil filter 5 under the drive of the push rod mechanism 7, thereby changing the inner layer oil filter 5 and the outer oil filter. The spacing between layers of oil filter screen 6. In this embodiment, the drive output end of the push rod mechanism 7 includes two lifting rods 71 ​​located on the left and right sides of the fan housing 2, and the lower ends of the lifting rods 71 ​​pass...

Abstract

An extractor hood comprises a machine shell, a draught fan located in the machine shell, a fume collecting hood located below the machine shell, and an oil-filter screen arranged at an air inlet of the fume collecting hood. The extractor hood is characterized in that the oil-filter screen is of a double-layer structure composed of an inner-layer oil-filter screen body and an outer-layer oil-filterscreen body, and the extractor hood further comprises a push rod mechanism; and one of the inner-layer oil-filter screen body and the outer-layer oil-filter screen body can make relative movement relative to the other oil-filter screen body under driving of the push rod mechanism, so that the distance between the two layers of oil-filter screen bodies is changed. The extractor hood has the advantages that according to the extractor hood, one of the inner-layer oil-filter screen body and the outer-layer oil-filter screen body can be driven to make relative movement relative to the other oil-filter screen body through the push rod mechanism, so that an inlet gap between the inner-layer oil-filter screen body and the outer-layer oil-filter screen body is changed, thus air volume change of the extractor hood is adjusted, and the extractor hood is located in the optimum working state all the time.

Description

technical field [0001] The invention relates to a range hood, in particular to an intelligent range hood and a control method thereof. Background technique [0002] The oil filter screen of the existing range hood is generally fixedly installed on the fume collecting hood, that is, the oil filter screen will not be adjusted adaptively with the change of the working condition of the range hood. , the air inlet area is generally not adjustable, that is, the degree of intelligence is low. In the prior art, a range hood with an adjustable air inlet surface is disclosed, such as the Chinese invention patent application "A Lifting and Adjustable Air Inlet Surface" disclosed by the application number 201410443175.X (the application publication number is CN 104296210A). Hood”, the range hood includes a fan cabinet and a fume collecting hood placed at the bottom of the fan cabinet. The fan cabinet includes a frame and a main unit built in the frame and lifted along the frame. There...
