[0029] In order to further understand the content, characteristics and effects of the utility model, the following embodiments are exemplified and described in detail as follows with reference to the drawings:

[0030] Please refer to Figure 1 The utility model discloses a kind of range hood, including range hood main body 1, range hood main body 1 has suction panel 11, top plate 12 and baffle 13, baffle 13 is located in the left and right sides of range hood main body 1, the upper edge of suction panel 11 is connected with the rear edge of top plate 12, suction panel 11 and top plate 12 are located between the baffle 13 of both sides, first suction port 111 is provided on suction panel 11 along its width direction, second suction port 121 is provided on top plate 12 along its width direction, first suction port 111 and second suction port 121 are all communicated with the smoke collecting cavity 14 of range hood main body 1.

[0031] In the embodiment, the smoke machine body 1 is provided with a smoke collecting cavity 14, the smoke collecting cavity 14 is communicated with the first air inlet 111 and the second air inlet 121, a smoke exhaust fan is installed in the smoke collecting cavity 14, and the smoke exhaust fan generates negative pressure at the first air inlet 111 and the second air inlet 121 when the smoke exhaust fan operates, so that the oil fume generated by the user during cooking can be sucked into the smoke collecting cavity 14 through the first air inlet 111 and the second air inlet 121 and finally exhausted by the smoke exhaust fan. The number of the wind baffles 13 is two, and the two wind baffles 13 are respectively arranged on the two sides of the smoke machine body 1, wherein the top side edge of the wind baffle 13 is connected with the top plate 12, the back side edge of the wind baffle 13 is connected with the air suction panel 11, and the connection position of the top side edge and the back side edge of the wind baffle 13 is connected with the connection position of the air suction panel 11 and the top plate 12.

[0032] When the smoke machine works, negative pressure is generated at the first air inlet 111 and the second air inlet 121, and the first air inlet 111 is closer to the stove than the second air inlet 121. When the generation speed of the oil fume is relatively fast, a large amount of oil fume flows to the first air inlet 111, part of the oil fume is sucked into the smoke collecting cavity 14 of the smoke machine by the first air inlet 111, and the oil fume that cannot be sucked by the first air inlet 111 flows upward along the air suction panel 11. After the oil fume flows above the first air inlet 111, part of the oil fume flows to the left and right sides and part of the oil fume flows forward under the flow blocking effect of the air suction panel 11. The oil fume flowing forward is sucked into the smoke collecting cavity 14 by the second air inlet 121, and the oil fume flowing to the left and right sides is blocked by the wind baffle 13 to avoid the oil fume from easily diffusing away from the smoke machine body 1, so as to prolong the stay time of the oil fume near the air suction panel 11 and the top plate 12 and make the oil fume more fully sucked into the smoke collecting cavity 14 by the first air inlet 111 and the second air inlet 121. In this way, the escape of the oil fume can be reduced, the suction effect of the smoke machine on the oil fume is improved, and the user experience is improved.

[0033] In the smoke machine of the utility model, as shown in the drawings, Figures 2 to 6 The first air inlet 111 is a hidden air inlet, the air suction panel 11 is provided with a gap, the back side of the air suction panel 11 is provided with a shielding plate 15, the shielding plate 15 is arranged along the width direction of the gap, the shielding plate 15 is arranged to be inclined from bottom to top and rearward, the rear projection of the gap falls into the shielding plate 15, and the gap between the upper edge of the gap and the upper edge of the shielding plate 15 forms the first air inlet 111. In the smoke machine of the utility model, the rear projection of the gap falls into the shielding plate 15, and when viewed from the air suction panel 11 on the user side, the user sees the shielding plate 15 and cannot see the back plate of the smoke collecting cavity 14 through the gap, so that the oil stains on the back plate of the smoke collecting cavity 14 cannot be seen by the user, the appearance of the smoke machine can be ensured, and the user experience is improved.

[0034] The smoke machine of the utility model, the lower edge of the baffle 15 extends to the inner side of the gap, the distance between the baffle 15 and the air suction panel 11 increases from the lower edge to the upper edge, the baffle 15 and the flow cross section of the gap form a flow channel, the flow channel connects the gap and the first air suction port 111, after the airflow flows into the gap, it first lands on the baffle 15, then flows to the first air suction port 111 along the flow channel, and then flows into the smoke collecting cavity 14 through the first air suction port 111.

[0035] When the user looks at the gap on the air suction panel 11, the baffle 15 can block the user's line of sight, preventing the user from directly seeing the back plate of the smoke collecting cavity 14 through the gap, so as to avoid affecting the user's visual perception of the smoke machine. Since the baffle 15 is arranged to be inclined backward from bottom to top, the gap between the upper edge of the baffle 15 and the upper edge of the air suction port forms a hidden first air suction port 111, after the oil fume flows into the gap and lands on the baffle 15, it can continue to flow into the smoke collecting cavity 14 through the first air suction port 111 upward, thereby avoiding the influence of the baffle 15 on the process of the oil fume flowing into the smoke collecting cavity 14, and ensuring the oil fume suction effect of the smoke machine.

[0036] In the smoke machine of the utility model, as shown in the drawings, Figure 4 The rear surface of the air suction panel 11 is provided with a reinforcing plate 16, the reinforcing plate 16 is provided with an avoiding opening 161, the avoiding opening 161 is arranged around the first air suction port 111, and the baffle 15 is arranged on the reinforcing plate 16. The first air suction port 111 is arranged on the air suction panel 11, thereby reducing the strength of the air suction panel 11, and the reinforcing plate 16 can enhance the strength of the air suction panel 11. The avoiding opening 161 on the reinforcing plate 16 corresponds to the first air suction port 111, and the avoiding opening 161 is larger than the gap, so as to avoid the influence of the periphery of the avoiding opening 161 on the air inlet amount of the gap. The avoiding opening 161 is formed on the reinforcing plate 16 by shearing and stamping, and the baffle 15 is also formed, so that the material utilization rate can be improved, and the process can be simplified.

[0037] In the smoke machine of the utility model, as shown in the drawings, Figure 3 The lower edge of the baffle 15 is provided with a first connecting part 151, the left side edge and the right side edge of the baffle 15 are provided with a second connecting part 152, the first connecting part 151 connects the lower edge of the avoiding opening 161, and the second connecting part 152 connects the left side edge / right side edge of the avoiding opening 161. The baffle 15 is formed on the reinforcing plate 16 by shearing and stamping, the first connecting part 151 and the second connecting part 152 make the connection between the baffle 15 and the reinforcing plate 16 smoother, so that the appearance requirement can be met, and the oil stains adhered to the baffle 15, the first connecting part 151 and the second connecting part 152 can be conveniently cleaned.

[0038] The first connecting part 151 is provided with an oil guide hole 1511, and the lower edge of the first air inlet 111 is provided with a flange 1111.

[0039] When the oil fume entering the smoke collection cavity 14 flows through the back of the air suction panel 11, the mixture of oil and water in the oil fume will adhere to the air suction panel 11, and the mixture of oil and water adhering to the back of the air suction panel 11 will flow downward after accumulating to a certain amount. The oil liquid above the first air inlet 111 flows downward along the air suction panel 11 and drips on the shielding plate 15, and then flows along the shielding plate 15 to the first connecting part 151. The oil guide hole 1511 can guide the oil liquid received by the first connecting part 151 to the bottom of the smoke machine main body 1, so as to prevent the oil liquid from overflowing the first air inlet 111 due to accumulation on the first connecting part 151, and to keep the surface of the air suction panel 11 clean. Part of the oil liquid may just drip on the lower edge of the first air inlet 111, and the oil liquid dripping on the lower edge of the first air inlet 111 can flow along the flange 1111 towards the inner side of the first air inlet 111 and finally flow onto the first connecting part 151. In this way, the oil fume dripping on the lower edge of the first air inlet 111 can be prevented from flowing to the outer surface of the air suction panel 11, so as to ensure that the outer surface of the air suction panel 11 is clean and tidy.

[0040] In the smoke machine of the utility model, as shown in the drawings, Figures 5 to 7 The first air inlet 111 is a hidden air inlet, the air suction panel 11 is provided with a notch, the lower edge of the notch extends inwardly into the smoke collection cavity 14 and is provided with a shielding plate 15, the shielding plate 15 is inclined from bottom to top and rearward, the height of the upper edge of the shielding plate 15 is not lower than the height of the upper edge of the notch, and the gap between the upper edge of the shielding plate 15 and the upper edge of the notch forms the first air inlet 111.

[0041] The shielding plate 15 extends from the lower edge of the notch towards the inner side of the notch, the distance between the shielding plate 15 and the air suction panel 11 increases from the lower edge to the upper edge, a flow passage is formed between the flow cross section of the shielding plate 15 and the notch, the flow passage connects the notch and the first air inlet 111, the airflow flows into the notch first, hits the shielding plate 15, then flows along the flow passage to the first air inlet 111, and finally flows into the smoke collection cavity 14 through the first air inlet 111. The shielding plate 15 is directly connected with the lower edge of the notch, that is, directly connected with the air suction panel 11. In actual application, the shielding plate 15 can be integrally formed with the air suction panel 11, so as to simplify the processing mode of the shielding plate 15.

[0042] The utility model discloses a smoke machine, the both sides of baffle 15 have the link plate 153, the link plate 153 is connected with the side edge of the corresponding side of the gap, the link plate 153 is arc, the upper edge of link plate 153 is the first arc edge that protrudes to the direction of the user side. The number of link plate 153 is two, and two link plates 153 are arranged at the both ends of baffle 15 respectively, and the end part side of baffle 15 is connected with the side edge of the gap by each link plate 153, so that baffle 15 and air suction panel 11 are connected as a whole in the visual sense, to improve the appearance integrity of smoke machine, and the link plate 153 can increase the connecting position of baffle 15 and air suction panel 11, to improve the connecting stability of baffle 15 and air suction panel 11. The one side of link plate 153 close to the gap is concave arc surface, and the upper edge of link plate 153 forms concave arc edge, so that the spacing between the upper edge of link plate 153 and the upper edge of the gap is increased as much as possible, thereby increasing the flow area of first air suction port 111, to improve the air intake of first air suction port 111.

[0043] As shown in Figures 5 to 7 , baffle 15 and link plate 153 are integrally formed with air suction panel 11. Air suction panel 11 is a sheet metal part, and baffle 15 and link plate 153 are both cut and punched on air suction panel 11, and the connection between link plate 153 and air suction panel 11 and baffle 15 is smoothly transitioned, to ensure the appearance of air suction panel 11. Moreover, due to the smoothly transitioned connection between link plate 153 and air suction panel 11 and baffle 15, it is convenient to clean after oil stains are attached on baffle 15 and link plate 153.

[0044] In the utility model discloses a smoke machine, as shown in Figure 5 and Figure 6 , the smoke machine further includes a reinforcing plate 16, the reinforcing plate 16 is arranged on the back side of the air suction panel 11, and the reinforcing plate 16 is provided with a supporting portion 162, and the supporting portion 162 is connected to the back side of the baffle 15. Since baffle 15 and link plate 153 are integrally cut and punched with air suction panel 11, the reinforcing plate 16 is arranged on the back side of air suction panel 11, and the supporting portion 162 of the reinforcing plate 16 is connected to the back side of baffle 15, so that the strength of the connection between link plate 153 and baffle 15 and air suction panel 11 can be ensured.

[0045] In the utility model discloses a smoke machine, as shown in Figure 1 , the smoke machine further includes a third air suction port 122, the third air suction port 122 is located on the back side of the second air suction port 121, the length of the third air suction port 122 is less than the length of the second air suction port 121, and the third air suction port 122 is arranged close to the left end and the right end of the air suction panel 11.

[0046] There are two third air suction ports 122 , and the two third air suction ports 122 are respectively close to the left end and the right end of the top plate 12 . The third air intake 122 is connected to the smoke collecting chamber 14. When the range hood is working, negative pressure will be generated at the first air intake 111, the second air intake 121 and the third air intake 122. The first air intake 111 is closer to the stove than the second air intake 121 and the third air intake 122. When the oil smoke is generated at a relatively fast speed, a large amount of oil smoke rushes to the first air intake 111, and part of the oil smoke is sucked into the smoke collecting chamber 14 of the range hood by the first air intake 111. The oil smoke that is not sucked into the smoke collecting chamber 14 of the range hood by the first air intake 111 will flow upward along the air suction panel 11. After the oil smoke flows to the top of the first air intake 111, part of it will flow to the left and right sides under the blocking effect of the top plate 12, and part will flow forward. The oil smoke flowing to the left and right sides will be sucked into the smoke collecting chamber 14 by the third air intake 122 near the left and right ends of the air suction panel 11, and the oil smoke flowing forward will be sucked into the smoke collecting chamber 14 by the second air intake 121. In this way, the oil smoke flowing through the top plate 12 can be fully sucked into the smoke collecting chamber 14, reducing the escape of oil smoke, thereby improving the oil smoke suction effect of the range hood and improving the user experience.

[0047] In the range hood of the present invention, a cavity is provided on the top plate 12, and the second air suction port 121 and the third air suction port 122 are provided in the cavity. The number of the cavity is one, and the number of the second air suction port 121 is one or two or more. One second air suction port 121 extends to both sides of the cavity along the width direction of the cavity, and its left side extends to the left end of the third air suction port 122 on the corresponding side, and its right side extends to the right end of the third air suction port 122 on the corresponding side; or two or more second air suction ports 121 are provided along the width direction of the cavity, and the left end of the leftmost second air suction port 121 extends to the left end of the third air suction port 122 on the corresponding side, and the right end of the rightmost second air suction port 121 extends to the right end of the third air suction port 122 on the corresponding side. The cavity can gather the oil smoke flowing to the top plate 12, thereby increasing the difficulty for the oil smoke to escape from the top plate 12 and prolonging the time for the oil smoke to flow along the top plate 12, thereby providing sufficient time for the second air suction port 121 and the third air suction port 122 to fully draw the oil smoke into the smoke collecting chamber 14.

[0048] In some embodiments, there is only one second air intake port 121, with the left end of the second air intake port 121 aligned with the left end of one of the third air intake ports 122, and the right end of the second air intake port 121 aligned with the right end of another of the third air intake ports 122. This improves the overall appearance of the top panel 12 while also allowing for the proper placement of the second and third air intake ports 121, 122 to ensure that any oil smoke entering the top panel 12 is adequately drawn into the smoke collection chamber 14.

[0049] In another embodiment, the number of the second air inlets 121 is one or two or more, and two or more second air inlets 121 are arranged along the width direction of the cavity, the left end of the leftmost second air inlet 121 extends to the left end of the corresponding third air inlet 122, and the right end of the rightmost second air inlet 121 extends to the right end of the corresponding third air inlet 122. As shown in Figure 1 and Figure 4 Taking two second air inlets 121 as an example, the left end of one of the second air inlets 121 is flush with the left end of one of the third air inlets 122, and the right end of the other second air inlet 121 is flush with the right end of the other third air inlet 122. Since the length of the second air inlet 121 is greater than the length of the third air inlet 122, the ends of the two second air inlets 121 close to each other can be close to the middle of the top plate 12. In this way, the appearance integrity of the top plate 12 can be improved, and the distribution positions of the second air inlets 121 and the third air inlets 122 can be reasonably arranged to ensure that the oil fume flowing to the top plate 12 is fully sucked into the smoke collecting cavity 14.
