[0030] In order to further understand the content, characteristics and effects of the present application, the following embodiments are exemplified and described in detail as follows in combination with the drawings:

[0031] Please refer to Figures 1 to 3 The present application discloses a kind of suction panel assemblies, for smoke machine, the suction panel assembly disclosed in the present application includes suction panel 1 and reinforcing plate 2, first suction port 11 is provided on suction panel 1, reinforcing plate 2 is equipped with baffle 21, baffle 21 is set to rearwards obliquely from bottom to top, reinforcing plate 2 is connected to the rear side of suction panel 1, the projection of first suction port 11 falls on baffle 21, and the gap between the upper edge of baffle 21 and the upper edge of first suction port 11 forms effective suction port.

[0032] In the embodiment, when the air suction panel assembly is installed on the smoke machine body 3, the air suction panel 1 can serve as the front panel of the smoke machine body 3. The smoke machine body 3 has a smoke collecting cavity 31, which is communicated with the first air suction port 11, and a smoke exhaust fan is installed in the smoke collecting cavity 31. When the smoke exhaust fan is running, negative pressure can be generated in the first air suction port 11, and the oil fume generated by the user during cooking is sucked into the smoke collecting cavity 31 through the first air suction port 11 and is finally exhausted by the smoke exhaust fan. The shielding plate 21 extends from the lower edge of the first air suction port 11 to the inner side of the first air suction port 11, the distance between the shielding plate 21 and the air suction panel 1 increases from the lower edge to the upper edge, the flow passage is formed between the shielding plate 21 and the flow cross section of the first air suction port 11, the flow passage communicates the first air suction port 11 and the effective air suction port, and after the airflow flows into the first air suction port 11, the airflow first hits on the shielding plate 21, then flows to the effective air suction port along the flow passage, and then flows into the smoke collecting cavity 31 through the effective air suction port.

[0033] After the air suction panel assembly of the utility model is installed on the smoke machine body 3, the projection of the first air suction port 11 falls on the shielding plate 21, and when the user looks at the air suction panel 1 from the user side, the user sees the shielding plate 21 and cannot see the back plate of the smoke collecting cavity 31 through the first air suction port 11, so that the oil stains on the back plate of the smoke collecting cavity 31 cannot be seen by the user, the appearance of the smoke machine can be ensured, and the user experience is improved.

[0034] When the air suction panel assembly is installed on the smoke machine body 3, when the user looks at the first air suction port 11 on the air suction panel 1, the shielding plate 21 can block the user's line of sight, so that the user cannot directly see the back plate of the smoke collecting cavity 31 through the first air suction port 11, so as to avoid affecting the visual sense of the user to the smoke machine. Since the shielding plate 21 is inclined from bottom to top and rearward, the gap between the upper edge of the shielding plate 21 and the upper edge of the first air suction port 11 forms the effective air suction port, and after the oil fume hits on the shielding plate 21 and flows into the smoke collecting cavity 31 through the effective air suction port, the oil fume can continue to flow into the smoke collecting cavity 31, so that the influence of the shielding plate 21 on the process of the oil fume flowing into the smoke collecting cavity 31 can be avoided, and the oil fume suction effect of the smoke machine can be ensured.

[0035] The effective air suction port is arranged on the air suction panel 1, the strength of the air suction panel 1 is reduced, and the reinforcing plate 2 can enhance the strength of the air suction panel 1.

[0036] In the air suction panel assembly of the utility model, Figure 2 and Figure 6As shown, the lower edge of the shielding plate 21 is provided with a first connecting part 22, and the shielding plate 21 is connected to the reinforcing plate 2 through the first connecting part 22. The first connecting part 22 can improve the connecting strength of the shielding plate 21 and the reinforcing plate 2, so that the shielding plate 21 and the reinforcing plate 2 can maintain a relatively stable relative position. The first connecting part 22 can also increase the spacing between the shielding plate 21 and the reinforcing plate 2, thereby increasing the spacing between the shielding plate 21 and the first air inlet 11. In this way, the space size of the flow passage formed between the shielding plate 21 and the first air inlet 11 can be increased, so that the flow passage can allow more oil fume to flow through.

[0037] As shown in the drawings, Figure 2 and Figure 6 As shown, the first connecting part 22 is provided with an oil guide hole 221. When the oil fume entering the smoke collecting cavity 31 flows through the back of the air suction panel 1, the mixture of oil and water in the oil fume will adhere to the air suction panel 1. When the mixture of oil and water adhering to the back of the air suction panel 1 accumulates to a certain amount, it will flow downward. The oil liquid above the first air inlet 11 flows downward along the air suction panel 1 and drips on the shielding plate 21, and then flows along the shielding plate 21 to the first connecting part 22. The oil guide hole 221 can guide the oil liquid received by the first connecting part 22 to the bottom of the smoke machine main body 3, preventing the oil liquid from overflowing the first air inlet 11 due to accumulation on the first connecting part 22, so as to keep the surface of the air suction panel 1 clean.

[0038] At least the lower edge of the first air inlet 11 is provided with a flange 111, and the flange 111 on the lower edge of the first air inlet 11 is inclined from top to bottom and rearward. The flange 111 on the lower edge of the first air inlet 11 is projected downward to fall into the first connecting part 22.

[0039] As shown in the drawings, Figure 2 and Figure 3 As shown, the reinforcing plate 2 is provided with a relief opening 23, and the relief opening 23 is arranged around the first air inlet 11. The lower edge of the relief opening 23 is connected to the first connecting part 22. The relief opening 23 on the reinforcing plate 2 corresponds to the effective air inlet, and the relief opening 23 is larger than the first air inlet 11, so as to avoid affecting the air inlet amount of the first air inlet 11 by the peripheral edge of the relief opening 23. The relief opening 23 is formed on the reinforcing plate 2 by shearing and stamping, and the shielding plate 21 is also formed at the same time. This not only improves the material utilization rate, but also simplifies the process.

[0040] When the reinforcing plate 2 is connected to the air suction panel 1, the lower edge of the relief opening 23 can be aligned with the lower edge of the first air inlet 11. By arranging the reinforcing plate 2 around the first air inlet 11, the connecting area of the air suction panel 1 and the reinforcing plate 2 can be increased, the connecting stability of the air suction panel 1 and the reinforcing plate 2 can be improved, and the reinforcing plate 2 can strengthen the positions around the first air inlet 11.

[0041] The air suction panel assembly of the utility model has the advantages of simple structure, convenient installation, convenient cleaning of oil stains, and the like. Figure 1 and Figure 2 As shown in the drawings, the left side edge and the right side edge of the shielding plate 21 are provided with second connecting parts 24, and the second connecting parts 24 are connected with the left side edge / right side edge of the avoiding opening 23. The number of the second connecting parts 24 is two, and the two second connecting parts 24 are respectively arranged at the two ends of the shielding plate 21. Each second connecting part 24 connects the end side edge of the shielding plate 21 with the side edge of the avoiding opening 23. In this way, the connecting position of the shielding plate 21 and the reinforcing plate 2 can be increased, so as to improve the connecting stability of the shielding plate 21 and the reinforcing plate 2.

[0042] The shielding plate 21 is sheared and punched on the reinforcing plate 2. The first connecting part 22 and the second connecting part 24 make the connection of the shielding plate 21 and the reinforcing plate 2 more smooth. The shielding plate 21, the first connecting part 22 and the second connecting part 24 can not only meet the appearance requirement, but also facilitate the cleaning of oil stains when the oil stains are attached to the shielding plate 21, the first connecting part 22 and the second connecting part 24.

[0043] The air suction panel assembly of the utility model has the advantages of simple structure, convenient installation, convenient cleaning of oil stains, and the like. Figure 1 and Figure 2 As shown in the drawings, the two side edges of the avoiding opening 23 are arc-shaped, the upper edge and the lower edge of the arc-shaped edge are respectively connected with the corresponding end of the upper edge and the corresponding end of the lower edge of the avoiding opening 23, and the corresponding edge of the second connecting part 24 is a second arc-shaped edge which is matched with the arc-shaped edge of the corresponding side of the avoiding opening 23. The upper edge of the second arc-shaped edge is connected with the corresponding end of the upper edge of the avoiding opening 23, and the lower edge of the second arc-shaped edge is connected with the corresponding end of the lower edge of the avoiding opening 23.

[0044] The two side edges of the avoiding opening 23 are concave arcs, and the second arc-shaped edges of the two second connecting parts 24 are respectively matched with the two side arc-shaped edges of the avoiding opening 23. In this way, the space size of the flow channel can be increased, so as to improve the amount of oil fume which can flow through the flow channel. The second connecting part 24 comprises a vertical edge, a first arc-shaped edge and a second arc-shaped edge. The vertical edge is connected with the corresponding side of the shielding plate 21. One end of the first arc-shaped edge is connected with the upper end of the vertical edge, and the other end of the first arc-shaped edge is connected with the upper end of the second arc-shaped edge. The lower end of the second arc-shaped edge is connected with the lower end of the vertical edge, and the second arc-shaped edge protrudes in the direction away from the user side.

[0045] The shielding plate 21 and the second connecting part 24 are integrally formed with the reinforcing plate 2. The reinforcing plate 2 is a sheet metal part, and the shielding plate 21 and the second connecting part 24 are sheared and punched on the reinforcing plate 2. The connection between the second connecting part 24 and the reinforcing plate 2 and the shielding plate 21 is smooth, so as to ensure the appearance of the reinforcing plate 2. In addition, due to the smooth connection between the second connecting part 24 and the reinforcing plate 2 and the shielding plate 21, the oil stains can be easily cleaned after being attached to the shielding plate 21 and the second connecting part 24.

[0046] The air suction panel assembly of the utility model has the advantages of simple structure, convenient installation, convenient cleaning of oil stains, and the like. Figure 4As shown, the two side edges of the first air inlet 11 are arc-shaped, and the upper edge and the lower edge of the arc-shaped edge are connected with the corresponding end of the upper edge and the corresponding end of the lower edge of the first air inlet 11 respectively, the width of the upper edge of the first air inlet 11 is greater than the width of the lower edge, and the left side edge and the right side edge of the first air inlet 11 are projected backward to fall into the second connecting part 24. The two side edges of the first air inlet 11 are concave arc-shaped, and the second arc-shaped edges of the two second connecting parts 24 are adapted to the two side arc-shaped edges of the first air inlet 11 respectively, so that the air inlet cross section of the first air inlet 11 can be increased to improve the air inlet amount of the first air inlet 11.

[0047] In the air suction panel assembly of the utility model, as shown in the drawings, Figure 3 As shown, the lower edge of the avoiding opening 23 extends backward from bottom to top to form a shielding plate 21, and the width of the shielding plate 21 is greater than the width of the first air inlet 11 and less than the width of the air suction panel 1. By setting the width of the shielding plate 21 to be greater than the width of the first air inlet 11, it can be ensured that when the user looks at the two ends of the first air inlet 11 at an oblique angle, the shielding plate 21 can also shield the user's line of sight, so that the shielding plate 21 can shield the line of sight of the back plate of the smoke collecting cavity 31 from various angles, thereby more comprehensively improving the user's experience when observing the range hood.

[0048] As shown in the drawings, Figure 4 and Figure 5 The utility model also provides a range hood which adopts the above-mentioned air suction panel assembly, and the range hood comprises a range hood body 3, the range hood body 3 has a smoke collecting cavity 31, the air suction panel assembly is connected to the range hood body 3, the air suction panel assembly forms the top plate and the front panel of the range hood body 3, the first air inlet 11 is arranged on the front panel, and the first air inlet 11 is communicated with the smoke collecting cavity 31.

[0049] The smoke exhaust fan is installed in the smoke collecting cavity 31, and the smoke exhaust fan can generate negative pressure in the first air inlet 11 when operating, oil fume generated by user's cooking is sucked into the smoke collecting cavity 31 through the first air inlet 11 and is finally exhausted by the smoke exhaust fan. The shielding plate 21 extends from the lower edge of the first air inlet 11 to the inner side of the first air inlet 11, the distance between the shielding plate 21 and the air suction panel 1 increases from the lower edge to the upper edge, the flow passage is formed between the shielding plate 21 and the flow cross section of the first air inlet 11, the flow passage communicates the first air inlet 11 and the effective air inlet, air flow flows into the first air inlet 11 first, then hits the shielding plate 21, then flows to the effective air inlet along the flow passage, and then flows into the smoke collecting cavity 31 through the effective air inlet.

[0050] In the range hood of the utility model, as shown in the drawings, Figure 4 , Figure 7 and Figure 8As shown, the top plate is further provided with a second air suction port 12 and a third air suction port 13, the second air suction port 12 is located at the rear side of the third air suction port 13, the length of the second air suction port 12 is less than that of the third air suction port 13, and the second air suction port 12 is arranged close to the left end and the right end of the top plate; the air suction panel 1 comprises a first part 1a, a second part 1b and a third part 1c, the first part 1a extends from front to back and forms the top plate of the range hood body 3, the third part 1c extends from top to bottom and forms the front panel of the range hood body 3, the second part 1b connects the first part 1a and the third part 1c, the first air suction port 11 is arranged on the third part 1c, and the second air suction port 12 and the third air suction port 13 are arranged on the first part 1a.

[0051] The range hood body 3 is provided with a smoke collecting cavity 31, the smoke collecting cavity 31 is in communication with the first air suction port 11, the second air suction port 12 and the third air suction port 13, and a smoke exhaust fan is installed in the smoke collecting cavity 31, the smoke exhaust fan can generate negative pressure in the first air suction port 11, the second air suction port 12 and the third air suction port 13 when operating, and the oil fume generated by the user during cooking can be sucked into the smoke collecting cavity 31 through the first air suction port 11, the second air suction port 12 and the third air suction port 13 and finally discharged by the smoke exhaust fan. The number of the second air suction port 12 is two, and the two second air suction ports 12 are respectively close to the left end and the right end of the air suction panel 1. The first air suction port 11, the second air suction port 12 and the third air suction port 13 are arranged along the width direction of the air suction panel 1.

[0052] When the range hood is working, negative pressure will be generated in the first air suction port 11, the second air suction port 12 and the third air suction port 13, and the first air suction port 11 is closer to the stove than the second air suction port 12 and the third air suction port 13, when the generation speed of the oil fume is relatively fast, a large amount of oil fume will flow to the first air suction port 11, part of the oil fume will be sucked into the smoke collecting cavity 31 of the range hood by the first air suction port 11, and the oil fume that cannot be sucked by the first air suction port 11 will flow upwards along the air suction panel 1, after flowing above the first air suction port 11, part of the oil fume will flow to the left and right sides under the blocking effect of the air suction panel 1, and part of the oil fume will flow forward or continue to flow upwards, the oil fume flowing to the left and right sides will be sucked into the smoke collecting cavity 31 by the second air suction port 12 close to the left end and the right end of the air suction panel 1, and the oil fume flowing forward or continuing to flow upwards will be sucked into the smoke collecting cavity 31 by the third air suction port 13. In this way, the oil fume flowing through the air suction panel 1 can be fully sucked into the smoke collecting cavity 31, reducing the escape of the oil fume, improving the suction effect of the range hood on the oil fume and improving the user experience.

[0053] The air suction panel 1 comprises a first portion 1a, a second portion 1b and a third portion 1c, the first portion 1a extends from front to back, the third portion 1c extends from top to bottom, the second portion 1b connects the first portion 1a and the third portion 1c, the first air suction port 11 is arranged on the third portion 1c, and the second air suction port 12 and the third air suction port 13 are arranged on the first portion 1a. The first portion 1a can serve as a top plate of the range hood main body 3, the third portion 1c can serve as a front panel of the range hood main body 3, and the second portion 1b connects the rear side edge of the top plate and the top side edge of the front panel. In this way, the first portion 1a, the second portion 1b and the third portion 1c together form a semi-enclosed smoke gathering space, so that even if the oil fume cannot be sucked into the first air suction port 11 in time and flows upward, it will first flow within the scope of the smoke gathering space, thereby delaying the time for the oil fume to escape from the vicinity of the range hood main body 3 and prolonging the residence time of the oil fume in the front side of the range hood main body 3. During this period, the second air suction port 12 and the third air suction port 13 can timely suck the oil fume in the smoke gathering space into the smoke collecting cavity 31, so as to reduce the oil fume escaping.

[0054] The second portion 1b is arc-shaped, the upper edge of the arc-shaped portion is connected with the first portion 1a, and the lower edge of the arc-shaped portion is connected with the third portion 1c, so that the air suction panel 1 smoothly transitions between the first portion 1a and the third portion 1c, so that the oil fume can flow more smoothly when changing the flow direction through the second portion 1b, and prevent air flow turbulence when the oil fume turns. In actual application, the first portion 1a, the second portion 1b and the third portion 1c can be integrally formed, so as to simplify the production and processing process of the air suction panel 1 and improve the structural stability of the air suction panel 1.

[0055] The second air inlet 12 is located at the rear side of the third air inlet 13 on the first part 1a. The oil fume that cannot be sucked by the first air inlet 11 flows along the third part 1c to the rear of the first part 1a. Under the blocking effect of the first part 1a, part of the oil fume flows to the left and right sides of the first part 1a, and another part of the oil fume flows from the rear to the front of the first part 1a. Since the second air inlet 12 is located at the rear side of the third air inlet 13 and close to the left and right ends of the first part 1a, the oil fume flowing to the left and right sides of the first part 1a is sucked into the smoke collecting cavity 31 by the second air inlet 12, and the oil fume flowing from the rear to the front of the first part 1a is sucked into the smoke collecting cavity 31 by the third air inlet 13. The positions of the second air inlet 12 and the third air inlet 13 are reasonably set according to different flow paths of the oil fume, so that the oil fume escaping in different directions can be fully sucked, and the suction effect of the oil fume is further improved. The second air inlet 12 and the third air inlet 13 are close to the rear side of the first part 1a on the first part 1a, that is, close to the third part 1c. The oil fume at the front side of the third part 1c flows to the rear side of the first part 1a under the negative pressure effect of the second air inlet 12 and the third air inlet 13, and does not directly flow to the front side of the first part 1a, so that the oil fume flowing to the rear of the first part 1a can be prevented from directly escaping from the front edge of the first part 1a, and the suction effect of the oil fume is further improved.

[0056] The first part 1a is provided with a cavity, and the second air inlet 12 and the third air inlet 13 are arranged in the cavity. The number of the cavity is one, and the number of the third air inlet 13 is one or two or more. One third air inlet 13 extends to the left end of the second air inlet 12 on the corresponding side and extends to the right end of the second air inlet 12 on the corresponding side along the width direction of the cavity. Or two or more third air inlets 13 are arranged along the width direction of the cavity. The left end of the leftmost third air inlet 13 extends to the left end of the second air inlet 12 on the corresponding side, and the right end of the rightmost third air inlet 13 extends to the right end of the second air inlet 12 on the corresponding side. The cavity can play a role of gathering the oil fume flowing to the first part 1a, so as to increase the difficulty of the oil fume escaping from the first part 1a, prolong the time of the oil fume flowing along the first part 1a, and provide sufficient time for the first air inlet 11 and the second air inlet 12 to fully suck the oil fume into the smoke collecting cavity 31.

[0057] In some embodiments, the number of the third air inlets 13 is one, the left end of the third air inlet 13 is flush with the left end of one of the second air inlets 12, and the right end of the third air inlet 13 is flush with the right end of the other second air inlet 12. In this way, the appearance integrity of the air suction panel 1 can be improved, and the distribution positions of the second air inlets 12 and the third air inlets 13 can be reasonably set to ensure that the oil fume flowing to the first part 1a is fully sucked into the smoke collecting cavity 31.

[0058] In another embodiment, the number of third air inlets is one or two or more, two or more third air inlets 13 are arranged along the width direction of the cavity, the left end of the leftmost third air inlet 13 extends to the left end of the corresponding second air inlet 12, and the right end of the rightmost third air inlet 13 extends to the right end of the corresponding second air inlet 12. As shown in Figure 1 and Figure 4 two third air inlets 13, one end of one third air inlet 13 is flush with the left end of one second air inlet 12, and the other end of the other third air inlet 13 is flush with the right end of the other second air inlet 12. Since the length of the third air inlet 13 is greater than the length of the second air inlet 12, the ends of the two third air inlets 13 close to each other can be close to the middle of the cavity bottom plate. In this way, the appearance integrity of the air suction panel 1 can be improved, and the distribution positions of the second air inlets 12 and the third air inlets 13 can be reasonably arranged to ensure that the oil fumes flowing to the first part la are fully sucked into the smoke collecting cavity 31.

[0059] As shown in Figure 8 In other embodiments, the first part la is provided with cavities, the second air inlets 12 and the third air inlets 13 are arranged in the cavities, and the number of cavities is two. One third air inlet 13 and one second air inlet 12 are arranged in each cavity. The third air inlet 13 extends along the width direction of the cavity, and the second air inlet 12 is arranged close to the left side / right side of the left / right cavity and extends to the left side / right side of the third air inlet 13. The two cavities are distributed along the width direction of the first part la, and can be defined as a left cavity and a right cavity. The second air inlet 12 in the left cavity is close to the left cavity wall, and the second air inlet 12 in the right cavity is close to the right cavity wall. The left end of the second air inlet 12 in the left cavity is flush with the left end of the third air inlet 13 in the left cavity. The right end of the second air inlet 12 in the right cavity is flush with the right end of the third air inlet 13 in the right cavity. By setting the number of cavities to two, the oil fumes can be divided when flowing to the first part la, avoiding the oil fume flow being disturbed when the oil fume flow just contacts the first part la and turning, so that the divided oil fume can be more timely and fully sucked into the smoke collecting cavity 31 by the second air inlets 12 and the third air inlets 13 in the two cavities.

[0060] In the embodiment with two cavities, the air suction panel 1 is also provided with a lighting window 14, and the hood body 3 also has an electric control cavity 33. The lighting lamp 4 is arranged in the electric control cavity 33, and the lighting side of the lighting lamp 4 is opposite to the lighting window 14. The lighting window 14 is arranged downward, the lighting lamp 4 is arranged in the lighting window 14, and the light emitted by the lighting lamp 4 can be downwardly irradiated through the lighting window 14, so as to illuminate the area where the user is located, thereby assisting the user's cooking process, and improving the use effect of the hood.

[0061] The left and right sides of the smoke machine body 3 are provided with wind baffles 32. The oil fume that is not timely sucked into the first air inlet 11 will not only flow upward, but also escape to the left and right sides of the front panel. The wind baffles 32 can block the oil fume escaping to the left and right sides, avoid the oil fume easily spreading in the direction away from the smoke machine body 3, prolong the stay time of the oil fume near the air suction panel 1 and the top plate, and make the oil fume more fully sucked into the smoke collecting cavity 31 by the second air inlet 12 and the third air inlet 13.

[0062] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement or improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
