Oil guide structure of range hood

Abstract

The invention relates to an oil guide structure of a range hood. The oil guide structure comprises a smoke collecting hood (1), a rectifying plate (2) and a driving mechanism (3). The front side faceof the smoke collecting hood (1) is provided with an air inlet (11), the rectifying plate (2) is obliquely arranged on the front side of the air inlet (11) of the smoke collecting hood (1), and the driving mechanism (3) is used for driving the rectifying plate (2) to open or close the air inlet (11). The oil guide structure is characterized by further comprising an oil guide plate (5) arranged below the rectifying plate (2), the front edge of the oil guide plate (5) is connected with the rectifying plate (2), and the rear edge of the oil guide plate (5) penetrates through the air inlet (11) and is always contained in an inner cavity of the smoke collecting hood (1).

Description

technical field

[0001] The invention relates to the field of range hoods, in particular to an oil guide structure of the range hood. Background technique

[0002] In the existing side suction range hood, in order to improve the effect of the range hood, a rectifying plate is arranged obliquely in front of the fume collecting hood corresponding to the position of the air inlet of the fume collecting hood. When the range hood is not working, the rectifying plate blocks the air inlet; when the range hood is working, the rectifying plate moves forward to open the air inlet, and a predetermined distance is maintained between the rectifying plate and the fume collecting hood, so that the air between the fume collecting hood and the rectifying A fume passage for the fume to pass is formed between the plates; and before the fume enters the fume passage, it first touches the rectifying plate, and the fume is separated for the first time on the rectifying board.

Examples

Embodiment 1

[0038] like Figure 1 to Figure 3 As shown, the oil guide structure of the range hood includes:

[0039] The smoke collecting hood 1 includes a backboard 12 , side panels 13 connected to both sides of the backplane 12 , and a front side panel 14 obliquely connected between the side panels 13 and on the backplane 12 , and the panel 14 is provided with an air inlet 11 .

[0040] The rectifying plate 2 is used to guide the oil fume, and is obliquely arranged on the front side of the fume collecting hood 1 corresponding to the air inlet 11 on the fume collecting hood 1; the angle between the rectifying plate 2 and the horizontal plane is 30-50°, In this embodiment, it is 40°.

[0041] The driving mechanism 3 is connected to the smoke collecting hood 1, connected to the rectifying plate 2, and used to drive the rectifying plate 2 to move so as to open or close the air inlet 11; including:

[0042] Driving device 31, can have multiple, present embodiment adopts electric push rod; ...

Embodiment 2

[0059] Such as Figure 4 with Figure 5 As shown, compared with Embodiment 1, this embodiment does not set a limit block, but a third crank 36 is hinged on the second crank 35, and the specific description is as follows:

[0060] There are two third cranks 36 , which are respectively connected to two second cranks. One end of the third crank is hinged on the handle body of the second crank 35 , and the second end of the third crank 36 is hinged to the second connecting plate 522 .

[0061] When the range hood is working, the movement of the second crank drives the movement of the third crank at the same time, and the end position of the connecting plate is limited by the third crank, so that the oil on the second connecting plate drops onto the inner surface of the fume collecting hood panel or directly Drops into the oil cup; when the rectifying plate is closed, the third crank pulls the second connecting plate to turn over. After the rectifying plate is closed in place, the...
