Technical Field

[0001] The utility model relates to a range hood structure, in particular to a range hood with precise oil smoke control. Background Art

[0002] For some range hoods on the market, when cooking produces a large amount of oil smoke, users increase the suction volume by increasing the fan air volume. However, increasing the air volume will generate greater noise, causing increased noise pollution in the kitchen.

[0003] Therefore, the existing technology is insufficient and needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the embodiment of the present invention is that when the oil smoke is large, the suction volume is increased by increasing the air volume of the fan, which will increase noise pollution.

[0029] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0031] It should also be understood that the terms used in this specification of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0032] See also Figure 1-4 The embodiment of the present invention provides a range hood with precise oil fume control, comprising a range hood body 1, an air inlet 2 and a smoke baffle 3. The air inlet 2 and the smoke baffle 3 are openably connected and are arranged below the range hood body 1. The air inlet 2 is connected to the range hood body 1. The smoke baffle 3 is used to block the escape of smoke and restrict the flow direction of smoke so that the smoke can smoothly enter the air inlet 2. The air inlet 2 is used for smoke to enter from the air inlet 2 and be discharged through the range hood body 1.

[0033] See also Figure 2The oil smoke precision control range hood also includes a push bag structure 4, which is protrudingly arranged on the side of the smoke baffle 3 near the air inlet 2. The setting of the push bag structure 4 increases the gas flow rate when the smoke passes through this area due to the sudden compression of the flow space, so that the smoke near the wall of the smoke baffle 3 quickly flows to the air inlet 2. It is possible to achieve the oil smoke extraction process when there is a lot of oil smoke without increasing the fan air volume, and it will not increase the noise in the kitchen, which is beneficial to the physical and mental health of the user. Preferably, the push bag structure 4 is a columnar structure. This structure is easy to manufacture and helps to reduce production costs, including but not limited to this, as long as the flow rate of the smoke is increased and the flow to the air inlet 2 is accelerated when the smoke passes through.

[0034] Please continue reading Figure 2 Preferably, the push bag structure 4 is arranged at the center of the smoke baffle 3, so that the smoke squeezed by the push bag structure 4 will not easily escape from the smoke baffle 3 outside the range of the smoke baffle 3 and the air inlet part 2.

[0035] See also Figure 1 、 Figure 3 The air inlet 2 of the present invention includes a shell body 5 and an air inlet plate 6 with an inverted trapezoidal structure. The inclined surface of the shell body 5 is an opening structure. The air inlet plate 6 is connected to the inclined surface of the shell body 5. The shell body 5 is communicated with the range hood main body 1. The smoke enters the shell body 5 through the air inlet plate 6, and enters the range hood main body 1 through the shell body 5 and is discharged. A first air inlet 7 and a second air inlet 8 are provided on the air inlet plate 6. The first air inlet 7 is arranged directly above the second air inlet 8, wherein the area of ​​the second air inlet 8 is larger than that of the first air inlet 7. The second air inlet 8 is the main inlet for the smoke passing through the air inlet plate 6. Part of the smoke that does not enter through the second air inlet 8 enters through the first air inlet 7 when adsorbed by the range hood main body 1, which can achieve more comprehensive adsorption of the smoke.

[0036] Please continue reading Figure 4 A buffer groove 9 is provided between the first air inlet 7 and the second air inlet 8. The buffer groove 9 is used for part of the smoke that has not entered from the second air inlet 8 to pass through when it is adsorbed and rises. Due to the sudden expansion of the flow space, the smoke flow is decelerated, which consumes part of the kinetic energy and avoids escaping from the range of the smoke baffle 3 and the air inlet 2 due to excessive flow speed. Side air inlets 10 are provided on both sides of the buffer groove 9, that is, on the left and right sides of the buffer groove 9. In the present utility model, the side air inlet 10 is opened in the vertical direction. The setting of the side air inlet 10 increases the adsorption capacity of the smoke within the range of the smoke baffle 3 and the air inlet 2, so that the smoke is better adsorbed, reduces the probability of smoke escape, and is conducive to improving the overall adsorption efficiency.

[0037] See also Figure 5As another embodiment of the present invention, the buffer groove 9 is close to the opening end of the first air inlet 7 and has a structure with a high middle and low ends, or refer to Figure 6 The buffer groove 9 directly below the first air inlet 7 is provided with a notch 11 on the opening end close to the first air inlet 7. One or more notches 11 can be provided, and the specific number can be determined comprehensively according to the size and number of the notches 11 to be provided. Figure 5 The structure and Figure 6 The setting of the middle notch 11 allows the smoke in the buffer groove 9 to be easily concentrated and guided to the first air inlet 7, reducing the possibility of smoke gathering and being difficult to flow out and escaping from the range of the smoke baffle 3 and the air inlet 2.

[0038] See also Figure 7 As another embodiment of the present invention, the side air inlet 10 is opened at an angle of 30-60 degrees with the vertical direction. Such a setting improves the interception ability of the smoke that is about to escape, which is beneficial to reducing the probability of smoke escape.
