Embodiment 1

[0057] figure 1 It is a schematic perspective view of the three-dimensional structure of the device 1 for enhancing the effect of oil extraction provided by Embodiment 1 of the present invention. figure 2 yes figure 1 Schematic diagram of the structure after part removal. image 3 yes figure 1 Front view of the structure. Figure 4 is along image 3 A sectional view of the line A-A in, Figure 5 is along image 3 Sectional view of the B-B line in .

[0058] combine figure 1 , figure 2 and image 3 , the device 1 for enhancing the effect of smoke extraction includes:

[0059] A plenum chamber 11, the plenum chamber 11 is surrounded by an inner shell 13 and an outer shell 14, the inner shell 13 includes a bottom wall 113 extending toward the outer shell 14, and a top wall is also arranged between the inner shell 13 and the outer shell 14 112, the top wall 112 connects the two casings 13 and 14; the casing 14 is provided with two air inlets 111; the inner casing 13 f...

Embodiment 2

[0074] In order to further enhance the voltage regulation effect, such as Figure 6 and Figure 7 As shown in the schematic diagram and cross-sectional view of device 2 in which part of the structure is removed, compared with device 1, the device 2 for enhancing the smoke extraction effect provided by the second embodiment extends the second side wall 121 into the plenum chamber 11 to A small pressure stabilizing chamber is formed between the second side wall 121 and the housing 14 . Fresh air enters the air inlet 111 (there are two in the present embodiment two, Figure 7 (1) is shown in the diagram for reasons of illustration, firstly it passes through the pressure stabilizing chamber 11 above the partition plate 16, flows into the area close to the inner shell 13, passes through the gas passage between the partition plate 16 and the inner shell 13, changes the flow direction, and flows into the compartment The pressure stabilizing chamber 11 below the plate 16 is called t...

Embodiment 3

[0078] The inventors of the present invention have found that the arrangement of multiple air inlets 111 can also increase the intake of fresh air to form a large negative pressure area. Compared with device 1, the device 3 for enhancing the smoke extraction effect provided by the third embodiment has four air inlets 111 on the casing 14. For details, refer to Figure 8 and Figure 9 shown. in, Figure 8 The front view of the device 3 for enhancing the smoke extraction effect, Figure 9 is along Figure 8 The profile of the B'-B' line in the middle.

[0079] The other structures of the device 3 are the same as those of the device 1, please refer to the first embodiment for the working process.

Abstract

The invention provides a device for enhancing smoke extraction effect. The device comprises a pressure stabilizing cavity and a wind direction change room, wherein the pressure stabilizing cavity is provided with an air inlet; the wind direction change room is communicated with the pressure stabilizing cavity and provided with an air outlet; and the wind direction changer room is suitable for enabling airflow discharged from the air outlet to form a rotating state. In addition, the invention also provides a method for enhancing the smoke extraction effect, and a smoke exhaust ventilator including the device for enhancing the smoke extraction effect. By adopting the technical scheme disclosed by the invention, the formed negative pressure zone is concentrated and extends downwards. Compared with the traditional smoke exhaust ventilator, the suspension height is reduced; the smoke extraction effect is obvious; smoke escape is reduced; the sight and the operation of a user are not affected; and the smoke exhaust ventilator is convenient to use. In addition, the device can achieve good smoke extraction effect with low air quantity, and has the advantage of being energy-saving.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a method and device for enhancing the effect of range hoods and a range hood containing the device. Background technique [0002] How to reduce the escape of oily fume, and then improve the effect of oily fume suction, has always been a technical problem that has attracted wide attention in this field, and it is directly related to the market competitiveness of range hood products. Aiming at the above-mentioned technical problems, various solutions have appeared in the prior art: for example, installing curtains to prevent oil fumes from escaping; another example, increasing the power of the fan system, etc. However, these existing solutions either have unsatisfactory effects, or bring new problems such as increased noise and increased energy consumption, and cannot fundamentally solve the above-mentioned technical problems. [0003] Based on this, the present invention prop...
