[0056] like Figure 1 and Figure 2 As shown, the smoke collection device 3 provided by this utility model includes: a shell, which includes a front plate 10 and a bottom plate 20.

[0057] Specifically, such as Figure 4 As shown, the front panel 10 includes an outer trim panel 11 and a back panel 12. The outer trim panel 11 can be made of glass, and the back panel 12 can be made of metal. The back panel 12 can be attached to the back of the outer trim panel 11 with adhesive. An oil-guiding structure is provided on the back panel 12.

[0058] like Figure 3 As shown, the base plate 20 is connected to the bottom of the front plate 10. The base plate 20 is provided with multiple smoke inlets 100, which are spaced apart in the left-right direction.

[0059] like Figure 2 As shown, an oil cup 4 is connected below the base plate 20. The oil cup 4 and the base plate 20 can be connected by hanging feet and hooks. An inlet 41 communicating with the inside and outside is provided on the side wall of the oil cup 4. In this embodiment, the inlet 41 is provided on the front side of the oil cup 4. In other feasible solutions, the inlet 41 can also be provided on other surfaces, such as the left side and the right side.

[0060] The outer casing has an internal fume duct that connects to the fan assembly. When the fan assembly is working, a negative pressure is created inside the fume duct. From the outside in, the inlet 41, the smoke inlet hole 100, and the fume duct are connected in sequence to form the bottom smoke inlet duct. The fumes pass through the inlet 41, then through the smoke inlet hole 100, and enter the interior of the fume duct before being discharged by the fan assembly.

[0061] The back of the front panel 10 is provided with an oil guiding structure to guide the oil condensation on the back of the front panel 10. The oil guiding structure has an oil discharge end. The oil guiding structure guides the oil on the back of the front panel 10 to flow toward the oil discharge end and finally leave from the oil discharge end. The downward projection of the oil discharge end is completely misaligned with the smoke inlet 100.

[0062] After the range hood starts working, the fumes first enter the inlet 41 of the oil cup 4, and then pass through the smoke inlet 100 before entering the smoke channel inside the outer casing. Through the bottom smoke inlet channel, the fumes can be drawn in from the bottom of the outer casing, thereby increasing the coverage area of ​​the range hood and reducing dead corners. Furthermore, when the fumes pass through the smoke channel, some of them will condense on the back of the front panel 10 and flow downwards. The oil guiding structure can catch the oil flowing down from the back of the front panel 10 and guide it in a fixed direction. That is, under the guidance of the oil guiding structure, the oil on the back of the front panel 10 will be discharged from the oil outlet of the oil guiding structure and detach from the back of the front panel 10. The downward projection of the oil outlet is completely misaligned with the smoke inlet 100 to prevent the oil detached from the back of the front panel 10 from passing through the smoke inlet 100 and falling onto the stovetop.

[0063] like Figure 4 - Figure 6 As shown, a connecting part 13 is provided below the back plate 12. The connecting part 13 is plate-shaped and roughly "L"-shaped with the back plate 12. The connecting part 13 is located above the bottom plate 20 and behind the smoke inlet 100. The connecting part 13 is connected to the bottom plate 20 by a first locking member. The connecting part 13 is connected to the oil drain end of the back plate 12 by a connecting rib 14. From front to back, the connecting rib 14 is inclined downward; the downward projection of the connecting rib 14 is completely misaligned with the smoke inlet 100.

[0064] like Figure 7 - Figure 9 As shown, the back plate 12, connecting rib 14, and connecting part 13 can be an integral structure. The connecting part 13 and the bottom plate 20 are connected together by a first locking element, such as a screw and nut. Then, the outer trim panel 11 is glued to the back plate 12 to improve the stability of the back plate 12. Furthermore, in order to avoid obstructing the smoke inlet 100, the connecting part 13 and the back plate 12 are connected by connecting rib 14. There can be multiple connecting ribs 14, which are arranged at intervals in the left and right direction. The gap between two adjacent connecting ribs 14 is used for the passage of oil fumes. In addition, the inclined connecting rib 14 can play the role of guiding oil. The oil flowing out from the oil discharge end of the oil guiding structure flows onto the connecting rib 14, and then the oil flows backward along the inclined connecting rib 14 and enters the connecting part 13 from above the smoke inlet 100. Furthermore, since the downward projection of the connecting rib 14 is completely misaligned with the smoke inlet 100, even if some oil drips from the connecting rib 14, it will not pass directly through the smoke inlet 100, but will fall onto the base plate 20.

[0065] like Figure 12As shown, the rear edge of the connecting part 13 can be located approximately above the second oil drain hole 34 of the base plate 20. That is, the oil flowing to the connecting part 13 can then flow backward and fall onto the bottom wall 310 of the recessed platform 300 of the base plate 20, and then flow into the oil cup 4 from the second oil drain hole 34 on the bottom wall 310.

[0066] like Figure 5 As shown, the lower end face of the back plate 12 has an upwardly extending notch, which includes a first inclined wall 210 and a second inclined wall 220 arranged at an angle. From top to bottom, the distance between the first inclined wall 210 and the second inclined wall 220 gradually increases. The lower ends of the first inclined wall 210 and the second inclined wall 220 both form oil drain ends.

[0067] Specifically, the notch can be formed by cutting the back plate 12. The notch includes a first inclined wall 210 and a second inclined wall 220 set at an angle. The first inclined wall 210 and the second inclined wall 220 are inverted "V" shape. The lower ends of the first inclined wall 210 and the second inclined wall 220 are oil drain ends. When the oil flowing down from above comes into contact with the first inclined wall 210 or the second inclined wall 220, it will flow along the inclined surface.

[0068] Specifically, in this embodiment, there are multiple notches. In two adjacent notches, the first inclined wall 210 of one notch and the second inclined wall 220 of the other notch are connected to the connecting part 13 by the same connecting rib 14. That is, the two notches guide the oil stains to one connecting rib 14, reducing the number of connecting ribs 14 and reducing the resistance of the connecting rib 14 to the oil fumes.

[0069] like Figure 6 As shown, there are at least two connecting ribs 14 with different lengths in the left and right directions. For example, the lengths of the connecting ribs 14 are L1 and L2, with L2 = 5 * L1. This is mainly to strengthen the connection and enhance the strength of the bottom of the back plate 12.

[0070] The smoke collection device 3 also includes a bottom connecting plate 30, which is located above the connecting part 13. The left and right ends of the bottom connecting plate 30 are connected to the left and right outer walls of the outer shell, respectively. The bottom connecting plate 30 is connected to the bottom plate 20 through a second locking member. The bottom connecting plate 30 has a guide slope 31, which slopes downward from front to back. A smoke guide hole 32 aligned with the smoke inlet hole 100 is provided on the guide slope 31.

[0071] like Figure 10 and Figure 11As shown, the bottom connecting plate 30 connects the left and right outer walls of the housing, increasing the overall stability of the housing structure. Furthermore, the bottom connecting plate 30 and the base plate 20 are connected together by a second locking element, such as screws and nuts, further increasing the stability of the base plate 20. Oil fumes passing through the gaps between the connecting ribs 14 will eventually enter the fan assembly through the oil guide holes of the guide slope 31. The smoke guide holes 32 on the inclined guide slope 31 prevent oil stains on the upper surface of the bottom connecting plate 30 from dripping from the oil guide holes; the oil stains will flow backward along the guide slope 31 and eventually fall into the oil cup 4 through the first oil leakage hole 33 on the rear side of the bottom connecting plate 30. The inclination angle F of the guide slope 31 is approximately 10°.

[0072] like Figure 9 and Figure 10 As shown, let the diameter of the smoke guide hole 32 be L6 and the diameter of the smoke inlet hole 100 be L3-1. Then L6 > L3-1, so as to avoid the smoke guide hole 32 blocking the smoke inlet hole 100.

[0073] like Figure 2 and Figure 3 As shown, a downwardly protruding recessed platform 300 is provided on the outer wall of the base plate 20. The recessed platform 300 is formed by stretching. Along the left-right direction, the cross-sectional shape of the recessed platform 300 is approximately trapezoidal, with a length of L4. The length of the inlet 41 of the oil cup 4 is L5, where L5 > L4, to prevent the oil cup 4 from obstructing the smoke inlet 100. The recessed platform 300 includes a bottom wall 310 and a front wall 320 connected to each other. The bottom wall 310 is arranged in the horizontal direction and has a second oil leakage hole 34. The downward projection of the second oil leakage hole 34 falls into the oil cup 4.

[0074] like Figure 2 As shown, from front to back, the front wall 320 slopes downward, the smoke inlet 100 is set on the front wall 320, and the projection of the lowest point of the front wall 320 downward falls into the oil cup 4. The oil stains on the outer side of the front wall 320 can flow downward along its outer side and fall into the oil cup 4 at the lowest position, while the oil stains on the inner side of the front wall 320 will flow onto the bottom wall 310 and then flow out from the second oil leakage hole 34.

[0075] The base plate 20 also includes an upper wall 330 connected to and located above the front wall 320. The upper wall 330 is vertically arranged, and the front wall 320 and the upper wall 330 are arranged at an angle. The upper wall 330 extends in the left and right direction, and its left and right ends can be flush with the outer trim panel 11 and attached to the lower outer wall of the outer trim panel 11. The upper wall 330 can cover the lower edge of the outer trim panel 11. Oil stains on the outer trim panel 11 can flow into the upper wall 330, and then flow down and up into the front wall 320, and finally fall into the oil cup 4.

[0076] To prevent oil stains dripping onto the front wall 320 from flowing out of the smoke inlet 100, the inner opening edge of the smoke inlet 100 is provided with a first flange 410 protruding inward. The first flange 410 has a certain height, thereby preventing oil stains from entering the smoke inlet 100.

[0077] like Figure 1 As shown, the smoke collection device 3 also includes a smoke collection hood 2, inside which a detection component is installed. The front panel of the smoke collection hood 2 is inclined downwards and forwards, and has a smoke inlet. A baffle 6 is rotatably connected to the front panel of the smoke collection hood 2; a decorative strip 5 located in front of the smoke inlet is also connected to the front panel of the smoke collection hood 2, wherein the decorative strip 5 is fixedly connected to the smoke collection hood 2.

[0078] The detection component is housed inside the fume hood 2. A first light-transmitting hole is provided on the front panel of the fume hood 2, and a second light-transmitting hole 71 is provided on the decorative strip 5. The first and second light-transmitting holes 71 are aligned front to back. The detection component detects the cooking environment through the first and second light-transmitting holes 71. When the baffle 6 is open or closed, it does not obstruct the second light-transmitting hole 71. The detection process of the component is not affected by the opening or closing of the baffle 6, facilitating its use at any time.

[0079] The decorative strip 5 is located below the baffle 6, and when the baffle 6 is closed, the decorative strip 5 can be coplanar with the baffle 6. Because the detection component is positioned close to the smoke inlet and at a higher elevation, it has a better field of view and can effectively ensure the detection range of the detection component.

[0080] The detection component can directly detect the cooking environment through the first and second light-transmitting holes 71. When the baffle 6 is closed, the outer wall of the baffle 6 is coplanar with the outer wall of the decorative strip 5. Both the baffle 6 and the decorative strip 5 can be made of glass, with the entire glass flap designed in segments: the upper segment is the baffle 6, and the lower segment is the decorative strip 5. The decorative strip 5 can also be made of sheet metal, while the baffle 6 is made of glass. The detection component can detect the cooking environment through the decorative strip 5, ensuring that the detection process is not affected by the opening or closing of the baffle 6. This allows the detection head of the component to directly detect temperature on the outer surface of the range hood, facilitating its immediate use.

[0081] The front panel of the smoke hood 2 is inclined relative to the vertical, that is, the front panel of the smoke hood 2 faces downward and forward, and the outer wall of the decorative strip 5 on it also faces downward and forward, thereby making the detection range wider.

[0082] In addition, the above-described embodiments make the decorative strip 5 and the baffle 6 appear as one piece when the baffle 6 is closed, resulting in a more aesthetically pleasing appearance.

[0083] like Figure 13As shown, the front panel 10 is located below the decorative strip 5, and there is a vertical gap 51 between them. The front edge of the bottom end face of the decorative strip 5 is higher than its rear edge, so that the oil stains on the surface of the decorative strip 5 are directed to the inner wall of the front panel 10.

[0084] During use, oil stains on the outer surface of the decorative strip 5 flow from top to bottom, then to its bottom end face. Guided by the inclined bottom end face, the oil is directed into the inner surface of the front panel 10, and then flows into the oil guiding structure on the back of the front panel 10. Finally, it flows into the oil cup 4 through the internal oil passage, effectively preventing oil stains on the surface of the decorative strip 5 from flowing directly to the outer surface of the front panel 10. The bottom end face of the decorative strip 5 can be an inclined plane or an inclined arc surface.

[0085] In this embodiment, the fume hood 2 and the outer casing are specifically arranged in a "7" shape. The fume hood 2 has a fume inlet. The fume collection device 3 serves both as an auxiliary fume extraction unit at the bottom of the machine and as a collection and diversion unit for the oil circuit.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
