[0002] Range hoods are important kitchen appliances. They are generally divided into top-mounted and side-mounted types. Top-mounted range hoods take up a lot of space and are easy to bump your head on, while side-mounted range hoods, although thinner, have insufficient suction power distribution, especially when dealing with stir-frying in Chinese cooking, where the escape of oil fumes is significant. Utility Model Content

[0003] This utility model provides a range hood housing structure and a range hood having the same, so as to at least solve some of the above-mentioned technical problems existing in the prior art.

[0004] In a first aspect, embodiments of the present invention provide a range hood housing structure, comprising: A horizontal protrusion extends forward from the top of the housing, and a first smoke inlet surface is formed on the underside of the horizontal protrusion. The first smoke inlet surface slopes downward from front to back and has a first smoke inlet. A vertical protrusion extends downward from the rear of the housing, and a second smoke inlet surface is formed on the front of the vertical protrusion. The second smoke inlet surface is inclined forward from bottom to top and has a second smoke inlet. A smoke-collecting plate is disposed on the first smoke inlet surface. The smoke-collecting plate can rotate relative to the first smoke inlet surface to open and close the first smoke inlet.

[0005] In an optional embodiment, the first smoke inlet surface is tilted downward at an angle of 10-25°, and the second smoke inlet surface is tilted forward at an angle of 20-35°.

[0006] In an optional embodiment, the first smoke inlet surface is tilted downward at an angle of 15-20°, and the second smoke inlet surface is tilted forward at an angle of 25-30°.

[0007] In an optional embodiment, the distance between the lower edge of the first smoke inlet and the upper edge of the second smoke inlet is 80-100mm.

[0008] In an optional embodiment, the first smoke inlet includes: Main smoke inlet; Two auxiliary smoke inlets are respectively located on the left and right sides of the main smoke inlet, and the area of ​​the auxiliary smoke inlets is smaller than the area of ​​the main smoke inlet.

[0009] In an optional embodiment, the second smoke inlet surface is provided with a lower decorative panel, and the main smoke inlet is provided with an oil mesh. The lower end of the oil mesh overlaps with the upper end of the lower decorative panel and is located inside the lower decorative panel.

[0010] In an optional embodiment, the two auxiliary smoke inlets are trapezoidal, and the shorter base of the trapezoid is located on the side away from the main smoke inlet; A first guide plate is provided above the two auxiliary smoke inlets, which guides the oil fumes to the smoke outlet at the top of the housing.

[0011] In an optional embodiment, a lower air guide structure is provided on the inner side of the second smoke inlet, and the cross-section of the lower air guide cavity formed by the lower air guide structure gradually decreases in the direction away from the second smoke inlet.

[0012] In an optional embodiment, the lower air guide structure includes an air guide fold and a lower air guide plate. A lower decorative bracket is provided on the second smoke inlet surface. The lower edge of the lower decorative bracket is bent backward to form the air guide fold. The air guide fold slopes downward from front to back. The air guide fold is located above the second smoke inlet. A lower air guide plate is provided below the smoke inlet. The lower air guide plate slopes upward from front to back. The air guide fold and the lower air guide plate gradually approach each other in a direction away from the second smoke inlet. The free end of the air guide fold is lower than the upper end of the lower air guide plate in the vertical direction.

[0013] Secondly, this utility model embodiment provides a range hood, including the range hood housing structure described in this utility model embodiment.

[0014] One embodiment of this utility model has the following advantages or beneficial effects: The range hood housing structure of this utility model embodiment includes a horizontal protrusion and a vertical protrusion. A first smoke inlet surface is formed on the lower part of the horizontal protrusion, and a first smoke inlet is present on the first smoke inlet surface. A second smoke inlet surface is formed on the front of the vertical protrusion, and a second smoke inlet is present on the second smoke inlet surface. This structure allows for a smaller thickness, reducing the space occupied in the kitchen. The second smoke inlet is closer to the cooking fumes, allowing them to quickly enter. Unabsorbed fumes rise to the first smoke inlet under the control of the smoke-collecting plate, reducing fume escape. The first smoke inlet surface slopes downwards from front to back, while the second smoke inlet surface slopes forwards from bottom to top, causing the negative pressure core area to shift downwards, shortening the fume capture time and further reducing fume escape.

The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0019] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0020] See Figures 1 to 7This utility model provides a range hood housing structure, including a horizontal protrusion 1 and a vertical protrusion 2. The horizontal protrusion 1 extends forward from the top of the housing, and a first smoke inlet surface 11 is formed on the bottom of the horizontal protrusion 1. The first smoke inlet surface 11 slopes downward from front to back, and a first smoke inlet 12 is provided on the first smoke inlet surface 11.

[0021] The vertical protrusion 2 extends downward from the rear of the housing, and a second smoke inlet surface 21 is formed on the front of the vertical protrusion 2. The second smoke inlet surface 21 is inclined forward from bottom to top, and a second smoke inlet 22 is provided on the second smoke inlet surface 21.

[0022] The smoke collecting plate 3 is located on the first smoke inlet surface 11. The smoke collecting plate 3 can rotate relative to the first smoke inlet surface 11 to open and close the first smoke inlet 12.

[0023] The range hood housing structure of this embodiment includes a horizontal protrusion 1 and a vertical protrusion 2. A first smoke inlet surface 11 is formed on the lower part of the horizontal protrusion 1, and a first smoke inlet 12 is provided on the first smoke inlet surface 11. A second smoke inlet surface 21 is formed on the front of the vertical protrusion 2, and a second smoke inlet 22 is provided on the second smoke inlet surface 21. This structure allows for a smaller thickness, reducing the space occupied in the kitchen. The second smoke inlet 22 is closer to the cooking fumes, allowing them to quickly enter. Unabsorbed fumes are gathered by the smoke-collecting plate 3 and rise to the first smoke inlet 12, reducing fume escape. The first smoke inlet surface 11 slopes downwards from front to back, while the second smoke inlet surface 21 slopes forwards from bottom to top, causing the negative pressure core area to shift downwards, shortening the fume capture time and reducing fume escape.

[0024] In some embodiments, the first smoke inlet surface 11 is tilted downwards at an angle of 10-25°, and the second smoke inlet surface 21 is tilted forward at an angle of 20-35°. This combined design of the tilt angles of the first and second smoke inlet surfaces 11 and 21 allows the negative pressure core area to shift downwards sufficiently, ensuring a good adsorption effect on cooking fumes. Avoiding an excessively small tilt angle results in a weak downward shift of negative pressure, and also increases the distance between the first smoke inlet 12 and the second smoke inlet 22. This can cause cooking fumes not absorbed by the second smoke inlet 22 to diffuse as they rise towards the first smoke inlet 12 due to the greater distance between them. When the tilt angle is too large, although the first smoke inlet 12 is closer to the source of the fumes, the grease accumulated on the oil mesh 7 at the first smoke inlet 12 is easy to drip directly, and the grease flowing down the oil mesh 7 is easy to flow onto the decorative surface of the second smoke inlet 21. At the same time, the distance between the first smoke inlet 12 and the smoke collection plate 3 becomes closer, affecting the air intake of the first smoke inlet 12. In addition, the excessive tilt angle makes the range hood resemble the new European-style side smoke hood, which is bulky and takes up too much space.

[0025] In some embodiments, the first smoke inlet surface 11 is tilted downward at an angle of 15-20°, and the second smoke inlet surface 21 is tilted forward at an angle of 25-30°. This combination of angles, compared to when the first smoke inlet surface 11 and the second smoke inlet surface 21 are not tilted, can shift the negative pressure core area downward by 5-10cm, thus shortening the oil fume capture time.

[0026] In some embodiments, the distance between the lower edge of the first smoke inlet 12 and the upper edge of the second smoke inlet 22 is 80mm-100mm. Maintaining an appropriate distance between the first smoke inlet 12 and the second smoke inlet 22 can reduce the escape of oil fumes that are not absorbed by the second smoke inlet 22, and can also maintain a reasonable distance between the first smoke inlet 12 and the smoke collecting plate 3, so as not to affect the air intake of the first smoke inlet 12.

[0027] In this embodiment of the utility model, the first smoke inlet surface 11 and the second smoke inlet surface 21 are inclined and form a parabolic structure with the smoke gathering plate 3, which ensures smooth air intake and reduces the escape of oil fumes.

[0028] In some embodiments, see Figure 3 The first smoke inlet 12 includes a main smoke inlet 121 and two auxiliary smoke inlets 122. The two auxiliary smoke inlets 122 are respectively located on the left and right sides of the main smoke inlet 121, and the area of ​​the auxiliary smoke inlets 122 is smaller than that of the main smoke inlet 121. The first smoke inlet 12 is arranged with one main smoke inlet 121 and two auxiliary smoke inlets 122, which increases the air intake area and improves the extraction effect of oil fumes.

[0029] In some embodiments, see Figure 3 The second smoke inlet surface 21 is provided with a lower decorative panel, and the main smoke inlet 121 is provided with an oil filter 7. The lower end of the oil filter 7 overlaps with the upper end of the lower decorative panel and is located inside the lower decorative panel. The oil filter 7 is inserted into the inside of the lower decorative panel, and the oil stains flowing down along the oil filter 7 can flow into the oil cup 4 at the bottom along the inside of the lower decorative panel, reducing oil stain leakage and keeping the exterior of the range hood clean.

[0030] In some embodiments, see Figure 3 The two auxiliary smoke inlets 122 are trapezoidal, with the shorter base of the trapezoid located away from the main smoke inlet 121. The trapezoidal shape of the two auxiliary smoke inlets 122 reduces the escape of oil fumes from the left and right sides, resulting in cleaner smoke extraction.

[0031] In some embodiments, see Figure 4 Above each of the two secondary smoke inlets 122, a first guide plate 8 is provided, which guides the fumes to the smoke outlet at the top of the casing. The first guide plate 8 is also provided on the left and right sides of the first smoke inlet 12 to guide the fumes drawn in by the first smoke inlet 12 to the smoke outlet at the top of the casing, thus allowing the first smoke inlet 12 to have a wider smoke intake range, smoother airflow, and reduced fume escape.

[0032] See Figure 4 The two first guide plates 8 gradually approach each other from bottom to top to gather and guide the oil fumes drawn in by the first smoke inlet 12 to the smoke outlet, enter the air handling unit above the casing, and finally be discharged.

[0033] In some embodiments, see Figure 5 The inner side of the second smoke inlet 22 is provided with a lower air guide structure 9. The cross-section of the lower air guide cavity 91 formed by the lower air guide structure 9 gradually decreases in the direction away from the second smoke inlet 22. The lower air guide cavity 91 forms a funnel shape, which makes the air intake smoother through the air pressure difference. It can draw most of the oil fumes closer to the second smoke inlet 22. The second smoke inlet 22, which is close to the oil fumes, draws in most of the oil fumes, which can reduce the escape of oil fumes.

[0034] In some embodiments, see Figure 6 The lower air guide structure 9 includes an air guide flange 93 and a lower air guide plate 94. A lower decorative bracket 92 is provided on the second smoke inlet surface 21. The lower edge of the lower decorative bracket 92 is bent backward to form the air guide flange 93. The air guide flange 93 slopes downward from front to back and is located above the second smoke inlet 22. The lower air guide plate 94 is provided below the smoke inlet and slopes upward from front to back. The air guide flange 93 and the lower air guide plate 94 gradually approach each other in a direction away from the second smoke inlet 22. The lower decorative panel can be fixed to the lower decorative bracket 92. The air guide flange 93 formed by bending the lower edge of the lower decorative bracket 92 and the lower air guide plate 94 together constitute the lower air guide structure 9, which can reduce the number of parts and facilitate assembly. The air guide flange 93 and the lower decorative bracket 92 are an integral structure, which can reduce oil leakage.

[0035] See Figure 7 The lower air guide plate 94 can have side folds 95 formed by bending forward on both the left and right sides. The side folds 95 can prevent the oil fumes from escaping to the left and right sides and guide the oil fumes upward into the air handling unit.

[0036] See Figure 7 The free end of the air guide fold 93 is lower than the upper end of the lower air guide plate 94 in the vertical direction. The fumes flow upward along the gap between the free end of the air guide fold 93 and the air guide plate, and the flow is smooth, which improves the smoke extraction effect of the second smoke inlet 22.

[0037] The upper end of the lower air guide plate 94 can be connected to the rear plate of the housing. The lower end of the lower air guide plate 94 can be connected to the bottom of the housing.

[0038] See Figures 1 to 7 This utility model provides a range hood, including the range hood housing structure of this utility model.

[0039] The range hood of this embodiment further includes a surrounding panel 5, which is located on the top of the housing. A fan housing may be installed inside the surrounding panel 5. The fan generates negative pressure, drawing fumes into the housing from the first smoke inlet 12 and the second smoke inlet 22, and then into the fan housing from the smoke outlet at the top of the housing, where they are finally discharged.
