Detailed Description

The invention will be further described with reference to the following examples.

The utility model discloses a slim smoke ventilator, as shown in fig. 1, fig. 3 and fig. 4, its structure is including casing 1 that has the inner chamber, and the roof 11 of casing 1 is opened there is air outlet 6, and the lower part of casing 1 is opened there is the inlet scoop, and the inlet scoop has two, and every inlet scoop all is equipped with air inlet screen board 3. Install worm wheel 2 in the cigarette machine cavity 8 of casing 1, the exit linkage air outlet 6 of worm wheel 2, the both sides of worm wheel 2 are equipped with left guide plate 4 and right guide plate 5 respectively. The bottom end of the left guide plate 4 is fixed at the bottom in the cigarette machine cavity 8 and clings to the inner wall of the left side plate 12 of the shell 1, and the bottom end of the right side plate 5 is fixed at the bottom in the cigarette machine cavity 8 and clings to the inner wall of the right side plate 13 of the shell 1. The top ends of the two guide plates 4 and 5 incline towards the middle, extend to the vicinity of the air outlet 6 and are tightly fixed with the top plate 11. The two guide plates 4 and 5 divide the smoke machine cavity 8 into three areas, namely a closed triangular area at the upper left corner and the upper right corner and an air inlet duct 7 in the middle area. The horizontal distance between the two guide plates 4 and 5 is gradually reduced from the air suction opening 7 to the air outlet 6, so that the purpose of gathering the smoke is achieved, and the smoke can be sucked away by the worm wheel 2 as soon as possible.

As shown in figures 1, 2 and 4, the length L of the slim type cigarette machine is 850mm to 900mm, and preferably the length L of the slim type cigarette machine is 895 mm. The thickness B of the thin type cigarette machine is 190mm to 230mm, and preferably, the thickness B is 210 mm. The distance between the left and right air deflectors 4, 5 at the top panel 11 is D, and the ratio D/L to the length L of the range hood is 0.4 to 0.95, preferably 0.41 in this embodiment. Under the condition of ensuring that the range hood is very thin, the range hood can also achieve larger air suction volume.

When the thin type range hood operates, oil smoke enters an air inlet duct 7 in the range hood through the air inlet mesh plate 3 and enters a worm gear system from an air suction opening of the worm gear 2 under the suction force of the worm gear 2. The oil smoke is at the in-process that gets into worm wheel 2 through air inlet duct 7, and air inlet duct 7's width evenly reduces, makes the velocity of flow accelerate, and two guide plates 4, 5's effect make more smooth and easy entering worm wheel 2 of oil smoke inside simultaneously, has reduced vortex and flow loss.

In addition, this embodiment smoke ventilator is ultra-thin smoke ventilator, and ultra-thin smoke ventilator's left and right sides length is longer, and this thin smoke ventilator's length L can reach 850mm to 900mm, and the left and right sides apart from longer thin worm gear system can produce great negative pressure in the otter board 3 department that admits air, and the cooking utensils generally are the both sides that live in separately for the double-range, therefore this smoke ventilator's negative pressure region can be fine cover the pan of both sides, and in addition two guide plates 4, 5's effect, the oil smoke is inhaled the smoke ventilator by the even suction of utmost speed in the otter board 3 department that.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
