Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a smoke hood and a range hood. Background Technology

[0002] During cooking, the emission of cooking fumes has always been a significant issue affecting quality of life. To address this problem, range hoods have become an indispensable kitchen appliance.

[0003] While existing range hoods can capture cooking fumes to some extent, their effectiveness remains significantly limited. For example, top-mounted range hoods, due to their high installation position, allow fumes to escape easily during their ascent; while side-mounted range hoods improve fume escape to some extent, they still struggle to completely capture fumes in cooking scenarios with large volumes of smoke. This results in some fumes not being effectively drawn in, thus reducing extraction efficiency. These issues make it difficult to completely remove kitchen fumes, affecting kitchen air quality and causing grease to adhere to walls and doors, which is difficult to clean and negatively impacts the user experience.

[0004] Therefore, there is an urgent need for fume hoods and range hoods that can capture cooking fumes more efficiently in order to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a smoke collection hood and a range hood to solve the problem in the related technology that some oil fumes cannot be effectively sucked in, resulting in low smoke extraction efficiency and affecting the user experience.

[0006] On one hand, this utility model provides a smoke collection hood, which is provided with a smoke collection chamber with an air outlet. The smoke collection hood includes a smoke baffle plate, which is inclined so that it is used to face the stove below the smoke collection hood. The smoke baffle plate is provided with a main air inlet, a first auxiliary air inlet and a second auxiliary air inlet that communicate with the smoke collection chamber. The first auxiliary air inlet and the second auxiliary air inlet are respectively arranged on both sides of the main air inlet in the vertical direction.

[0007] As a preferred technical solution for the smoke collection hood, the smoke baffle includes a first baffle and a second baffle connected to each other. The second baffle is located on the side of the first baffle away from the stove. The second baffle and the first baffle form a preset angle α. The value range of the preset angle α is: α < 180°.

[0008] The main air inlet is disposed on the first baffle, the first auxiliary air inlet is disposed on the first baffle and located on the side of the main air inlet closer to the stove, and the second auxiliary air inlet includes a first branch air inlet, which is disposed on the second baffle.

[0009] As a preferred technical solution for the smoke collection hood, the smoke collection hood further includes two side baffles respectively disposed on both sides of the smoke baffle in the left-right direction;

[0010] The first air inlet extends along the left-right direction to the two side baffles.

[0011] As a preferred technical solution for the smoke hood, the second auxiliary air inlet further includes a second branch air inlet, which is disposed on the first baffle and located between the main air inlet and the first branch air inlet.

[0012] As a preferred technical solution for the smoke hood, there are two second air inlets, and the two second air inlets are respectively arranged adjacent to the two side baffles;

[0013] The distance of the second air inlet along the left and right direction is L, and the shortest distance between the side baffle and the main air inlet is l, where L≥l.

[0014] As a preferred technical solution for the smoke hood, the smoke hood further includes a guide plate, which is disposed on the first baffle and located between the main air inlet and the first branch air inlet. The guide plate extends along the left-right direction and has an arc-shaped cross-section.

[0015] As a preferred technical solution for the smoke hood, there are two main air inlets, which are spaced apart in the left-right direction.

[0016] As a preferred technical solution for the smoke collection hood, the smoke collection hood further includes a grille plate, which is used to cover the first auxiliary air inlet.

[0017] On the other hand, the present invention provides a range hood, including a main unit and a smoke collection hood as described in any of the above embodiments, wherein the air intake of the main unit is connected to the air outlet of the smoke collection hood.

[0018] As a preferred technical solution for the range hood, it also includes an auxiliary fan, which is disposed in the smoke collection chamber and opposite to the main air inlet.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model provides a smoke collection hood and a range hood. The smoke collection hood is provided with a smoke collection chamber with an air outlet. The smoke collection hood includes a smoke baffle plate, which is inclined so that it is used to face the stove below the smoke collection hood. The smoke baffle plate is provided with a main air inlet, a first auxiliary air inlet and a second auxiliary air inlet that are connected to the smoke collection chamber. The first auxiliary air inlet and the second auxiliary air inlet are respectively provided on both sides of the main air inlet in the vertical direction. When the range hood is fixed above the stove, the baffle plate is opposite to the stove. Taking the first auxiliary air inlet as being below the main air inlet as an example, when the main fan of the range hood is working, since the air outlet of the smoke collection hood is connected to the air inlet of the main fan, the main fan creates negative pressure in the smoke collection chamber. This negative pressure then creates negative pressure in the main air inlet, the first auxiliary air inlet, and the second auxiliary air inlet. At this time, since the first auxiliary air inlet is closest to the stove, some of the fumes generated during cooking can be diverted by the first auxiliary air inlet in advance, reducing the amount of fumes drawn in by the main air inlet. Subsequently, most of the fumes are drawn into the smoke collection chamber by the main air inlet. However, some fumes are still not drawn into the smoke collection chamber by the main air inlet and the first auxiliary air inlet. At this time, since the second auxiliary air inlet is located above the main air inlet, the second auxiliary air inlet absorbs the remaining escaping fumes, ultimately improving the smoke extraction efficiency of the range hood equipped with the smoke hood and enhancing the user experience.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-3As shown, this embodiment provides a smoke collection hood. The smoke collection hood 1 is provided with a smoke collection chamber 11 with an air outlet. The smoke collection hood 1 includes a smoke baffle 12, which is inclined so that it is used to face the stove below the smoke collection hood 1. The smoke baffle 12 is provided with a main air inlet 1211, a first auxiliary air inlet 1212 and a second auxiliary air inlet that communicate with the smoke collection chamber 11. The first auxiliary air inlet 1212 and the second auxiliary air inlet are respectively provided on both sides of the main air inlet 1211 along the vertical direction Z. When the range hood is fixed above the stove, the baffle 12 is opposite to the stove. Taking the first auxiliary air inlet 1212 located below the main air inlet 1211 as an example, when the main fan 22 of the range hood is working, since the air outlet of the smoke collection hood 1 is connected to the air inlet of the main fan 22, the main fan 22 creates negative pressure in the smoke collection chamber 11, which in turn creates negative pressure in the main air inlet 1211, the first auxiliary air inlet 1212, and the second auxiliary air inlet. At this time, since the first auxiliary air inlet 1212 is closest to the stove, the smoke generated during cooking is absorbed more effectively. The cooking fumes can be partially diverted by the first auxiliary air inlet 1212 in advance to reduce the amount of cooking fumes drawn in by the main air inlet 1211. Subsequently, most of the cooking fumes are drawn into the smoke collection chamber 11 by the main air inlet 1211. However, some cooking fumes are still not drawn into the smoke collection chamber 11 by the main air inlet 1211 and the first auxiliary air inlet 1212. At this time, since the second auxiliary air inlet is located above the main air inlet 1211, the second auxiliary air inlet absorbs the remaining cooking fumes that have escaped, thus improving the smoke extraction efficiency of the range hood equipped with the smoke hood and enhancing the user experience.

[0033] Optionally, the smoke hood 1 includes a smoke baffle 12, two side baffles 13, a back plate 16, a bottom baffle 17, and a top baffle 18. The smoke baffle 12 and the back plate 16 are spaced apart along the front-to-back direction Y, the two side baffles 13 are spaced apart along the left-to-right direction X, and the bottom baffle 17 and the top baffle 18 are spaced apart along the up-down direction Z. The smoke baffle 12, the two side baffles 13, the back plate 16, the bottom baffle 17, and the top baffle 18 together form a smoke collection chamber 11.

[0034] Optionally, the smoke baffle 12 includes a first baffle 121 and a second baffle 122 connected to each other. The second baffle 122 is located on the side of the first baffle 121 away from the stove. The second baffle 122 and the first baffle 121 form a preset angle α, where α < 180°. The main air inlet 1211 is disposed on the first baffle 121, and the first auxiliary air inlet 1212 is disposed on the first baffle 121 and located on the side of the main air inlet 1211 closer to the stove. The second auxiliary air inlet includes a first branch air inlet 1221, which is disposed on the second baffle 122. In this embodiment, the first auxiliary air inlet 1212 is used to absorb the fumes between the main air inlet 1211 and the stove, and the second auxiliary air inlet is used to absorb the fumes between the main air inlet 1211 and the top baffle 18. The second baffle 122 forms a preset angle α with the first baffle 121. The first air inlet 1221 is disposed on the second baffle 122. This arrangement can further increase the contact area between the first air inlet 1221 and the main air inlet 1211 and the top baffle 18, thereby improving the smoke extraction efficiency of the first air inlet 1221. The value of α can be 175°, 170°, 165°, 160°, 155°, 90°, and 45°, etc.

[0035] Optionally, the first baffle 121 forms a preset angle b with the horizontal plane, thereby tilting the smoke baffle 12 towards the stove. This arrangement helps to increase the contact area between the smoke generated during cooking and the smoke baffle 12, thus improving the efficiency of the main air inlet 1211, the first auxiliary air inlet 1212, and the second auxiliary air inlet in absorbing cooking fumes. For example, the value of b can be 80°, 75°, 70°, 65°, and 60°, etc.

[0036] Optionally, the first baffle 121 and the second baffle 122 are fixedly connected to each other. In other embodiments, the first baffle 121 and the second baffle 122 are pivotally connected to each other, thereby adjusting the included angle between the first baffle 121 and the second baffle 122 to adjust the suction efficiency of the first air inlet 1221 for oil fumes.

[0037] Optionally, the first air inlet 1221 extends along the left-right direction X to the two side baffles 13. In this embodiment, this arrangement can effectively increase the oil fume absorption area of ​​the first air inlet 1221, thereby preventing the escape of oil fumes.

[0038] Optionally, a mesh plate is fixed on the second baffle 122, which covers the first air inlet 1221. In this embodiment, compared with the open design of the first air inlet 1221, this design can further increase the negative pressure at the first air inlet 1221, thereby improving the smoke extraction efficiency.

[0039] Optionally, the second auxiliary air inlet further includes a second branch air inlet 1213, which is disposed on the first baffle 121 and located between the main air inlet 1211 and the first branch air inlet 1221. In this embodiment, the second branch air inlet 1213 can further improve the smoke extraction efficiency of the smoke collection hood 1.

[0040] Optionally, two second air inlets 1213 are provided, each adjacent to one of the two side baffles 13. The distance between the second air inlets 1213 in the left-right direction X is L, and the shortest distance between the side baffles 13 and the main air inlet 1211 is l, where L ≥ l. In this embodiment, there is a gap between the main air inlet 1211 and the two side baffles 13. When the range hood is working, some oil fumes still remain in the area between the main air inlet 1211 and the side baffles 13. To prevent the escape of these oil fumes, the length L of the second air inlet 1213 is made greater than the shortest distance l between the side baffles 13 and the main air inlet 1211, so that these oil fumes are drawn into the smoke collection chamber 11 by the second air inlet 1213.

[0041] Optionally, the fume hood 1 further includes a guide plate 14, which is disposed on the first baffle 121 and located between the main air inlet 1211 and the first auxiliary air inlet 1221. The guide plate 14 extends in the left-right direction X, and its cross-section is arc-shaped. In this embodiment, the guide plate 14 can generate a wall-attaching effect on the fumes above the main air inlet 1211, preventing these fumes from moving away from the fume hood 1, thereby improving the smoke extraction efficiency of the second auxiliary air inlet.

[0042] Optionally, two main air inlets 1211 are provided, and the two main air inlets 1211 are spaced apart in the left-right direction X. In this embodiment, the two main air inlets 1211 correspond one-to-one with the two burners on the stove, so that the two main air inlets 1211 are respectively opposite to the pots on the two burners, thereby improving the smoke extraction efficiency of the main air inlets 1211.

[0043] Optionally, the smoke hood 1 further includes a grille plate 15, which is used to cover the first auxiliary air inlet 1212. In this embodiment, compared with the first auxiliary air inlet 1212 being hollowed out, the grille plate 15 is used to cover the first auxiliary air inlet 1212, thereby increasing the negative pressure at the first auxiliary air inlet 1212 and improving the suction capacity for external gas.

[0044] Optionally, the smoke baffle 12, the bottom baffle 17 and the two side baffles 13 are arranged to form a first auxiliary air inlet 1212, and the grille 15 is fixedly connected to the two side baffles 13 to achieve the effect of covering the first auxiliary air inlet 1212.

[0045] Optionally, a louvered air vent 19 is provided on the side of the first baffle 121 opposite to the bottom baffle 17. The louvered air vent 19 can play a role in diverting the oil fumes generated during cooking into two parts: one part enters the first auxiliary air inlet 1212, and the other part enters the main air inlet 1211 and the second auxiliary air inlet.

[0046] This embodiment also provides a range hood, including a main unit 2 and a smoke collection hood 1 as described above. The air intake of the main unit 2 is connected to the air outlet of the smoke collection hood 1. In this embodiment, the main unit 2 includes a housing 21 and a main fan 22 located inside the housing 21. The air intake of the housing 21 is connected to the air outlet of the smoke collection hood 1, and the air outlet of the housing 21 is connected to the exhaust pipe. When the main fan 22 inside the housing 21 is working, it creates a negative pressure in sequence inside the housing 21 and the smoke collection chamber 11, so as to draw external fumes into the smoke collection chamber 11 through the main air inlet 1211, the first auxiliary air inlet 1212, and the second auxiliary air inlet, and then into the housing 21, and finally discharged outdoors through the exhaust pipe.

[0047] Optionally, the range hood also includes an auxiliary fan 3, which is disposed in the smoke collection chamber 11 and opposite to the main air inlet 1211. In this embodiment, when the auxiliary fan 3 is working, it can further enhance the negative pressure value of the main air inlet 1211, provided that the main fan 22 has already provided negative pressure to the main air inlet 1211.

[0048] Optionally, there are two auxiliary fans 3, with each auxiliary fan 3 corresponding to one of the two main air inlets 1211.

[0049] Optionally, the range hood also includes two rectifier nets 4, which are located outside the smoke collection chamber 11 and are respectively arranged at the two main air inlets 1211. This arrangement can rectify the disordered oil fume gas into an orderly oil fume gas, thereby improving the smoke extraction efficiency of the main air inlets 1211.
