[0024] 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 in combination with the drawings:

[0025] Please refer to Figures 1 to 3The utility model discloses a range hood, which includes a range hood body 1, which has a front panel 11 and a top panel 12. The front panel 11 is provided with a first air suction port 111 along its left and right directions. A group of air suction port groups is provided on the left and right sides of the top panel 12, each of which includes a plurality of second air suction ports 121. The second air suction ports 121 in the same group of air suction port groups are arranged in a plurality of rows along the front and rear directions of the top panel 12, and each second air suction port 121 extends along the left and right directions of the top panel 12. The first air suction port 111 and the second air suction port 121 are both connected to the smoke collecting chamber of the range hood body 1.

[0026] In this embodiment, the top side of the front panel 11 is connected to the rear side of the top panel 12. A smoke exhaust fan is installed in the smoke collection chamber. When the smoke exhaust fan is in operation, it can generate negative pressure at the first air intake port 111 and the second air intake port 121. The oil smoke generated by the user's cooking is sucked into the smoke collection chamber through the first air intake port 111 and the second air intake port 121 and finally exhausted by the smoke exhaust fan. The first air intake port 111 is long and extends in the left-right direction of the front panel 11. The number of second air intake ports 121 is at least two and is divided into two groups. The two groups of second air intake ports 121 are arranged in the left-right direction of the top panel 12, and each group of second air intake ports 121 is arranged in several rows in the front-to-back direction. For example, the number of second air intake ports 121 can be six, and the six second air intake ports 121 are arranged in two columns and three rows. Dividing the second air intake ports 121 into two groups and arranging them on the left and right sides of the top panel 12 of the range hood enhances the suction range on the left and right sides of the top panel 12.

[0027] When the range hood is operating, negative pressure is generated at both the first air inlet 111 and the second air inlet 121. The first air inlet 111 is closer to the stove. When the speed of oil smoke generation is relatively fast, a large amount of oil smoke rushes to the first air inlet 111. Some of the oil smoke is sucked into the smoke collection chamber by the first air inlet 111. The oil smoke that is not sucked by the first air inlet 111 in time will flow upward along the front panel 11. After flowing to the top plate 12, the oil smoke will flow toward the front and left and right sides, and will eventually be sucked into the smoke collection chamber by the second air inlet 121. Even if the oil smoke flowing forward does not have time to be sucked by the second air inlet 121 in the rear row, it can still be sucked by the second air inlet 121 in the front row while continuing to flow. In this way, the oil smoke flowing through the range hood body 1 can be fully sucked into the smoke collection chamber, reducing oil smoke escape, thereby improving the range hood's oil smoke extraction effect and improving the user experience.

[0028] In the smoke machine of the present invention, Figures 1 to 3 As shown, the second air intake ports 121 in each air intake port group are arranged in a one-to-one correspondence in each row. This not only improves the appearance of the top plate 12, but also allows for the reasonable distribution of the second air intake ports 121 to ensure that the oil smoke flowing into the top plate 12 is fully drawn into the smoke collecting chamber.

[0029] In the smoke machine of the present invention,Figures 1 to 3 As shown in the drawings, the two groups of air inlets on the left and right sides of the top plate 12 are symmetrically arranged and are arranged on the top plate 12 close to the rear side of the top plate 12. The symmetric arrangement of the air inlet groups can improve the appearance integrity of the top plate 12. The air inlet groups are arranged on the top plate 12 close to the rear side of the top plate 12, that is, close to the front panel 11. The oil fume on the front side of the front panel 11 will flow to the rear side of the top plate 12 under the negative pressure action of the second air inlet 121, and will not directly flow to the front side of the top plate 12, thereby preventing the oil fume from flowing to the rear side of the top plate 12 and directly escaping from the front edge of the top plate 12, and further improving the suction effect on the oil fume.

[0030] In the smoke machine of the utility model, as shown in the drawings, Figures 1 to 3 As shown in the drawings, the distance between the left side edge of the left group of air inlets and the right side edge of the right group of air inlets is not less than the width of the first air inlet 111. The distance between the left side edge of the left group of air inlets and the left side edge of the top plate 12 is not greater than the distance between the left side edge of the first air inlet 111 and the left side edge of the front panel 11, and the distance between the right side edge of the right group of air inlets and the right side edge of the top plate 12 is not greater than the distance between the right side edge of the first air inlet 111 and the right side edge of the front panel 11. When the oil fume enters the smoke collecting cavity through the first air inlet 111, part of the oil fume escapes through the two sides of the first air inlet 111 and is sucked by the second air inlets 121 of the two groups of air inlets, which can improve the purification effect of the smoke machine on the oil fume.

[0031] In the smoke machine of the utility model, the distance between the right side edge of the left group of air inlets and the left side edge of the right group of air inlets is not greater than the width of the first air inlet 111. In this way, the left group of air inlets and the right group of air inlets can have an overlapping part with the first air inlet 111 in the flow path of the oil fume, so that the oil fume that has not been sucked into the smoke collecting cavity by the first air inlet 111 can be sucked into the smoke machine by the left and right groups of air inlets after flowing to the top plate 12, thereby further reducing the escape of the oil fume and improving the suction effect of the smoke machine on the oil fume.

[0032] In the smoke machine of the utility model, as shown in the drawings, Figures 1 to 3 As shown in the drawings, the top plate 12 is provided with a cavity, and the air inlet group is arranged in the cavity. The cavity can gather the oil fume flowing to the top plate 12, increase the difficulty of the oil fume escaping from the top plate 12, prolong the time of the oil fume flowing along the top plate 12, and thus provide sufficient time for the air inlet group to fully suck the oil fume into the smoke collecting cavity.

[0033] As shown in the drawings, Figure 2As shown, in other embodiments, the top plate 12 includes a top surface 12a, a side wall surface 12b, a front side wall surface 12c, and a bottom surface 12d, the front edge of the top surface 12a is connected with the front side wall surface 12c, the left and right side edges of the top surface 12a are connected with the side wall surface 12b, the bottom surface 12d has a clearance adapted to the top surface 12a, the lower edges of the side wall surface 12b and the front side wall surface 12c are connected with the corresponding sides of the clearance, the rear edges of the side wall surface 12b and the bottom surface 12d are connected with the front panel 11, the rear edge of the top surface 12a is connected with the upper edge of the front panel 11, and the suction port group is arranged on the top surface 12a. The top surface 12a, the side wall surface 12b, the front side wall surface 12c, and the bottom surface 12d enclose a cavity with the top surface 12a as the top, the bottom surface 12d as the bottom, and without a rear side wall surface, the front panel 11 extends upward and is connected with the rear edge of the top surface 12a, when the oil fume enters the smoke collecting cavity through the first suction port 111, part of the oil fume escapes after passing through the first suction port 111, and then moves upward along the front panel 11 under the action of the suction port group on the top plate 12 and is sucked by the suction port group on the top plate 12, the side wall surface 12b forms a smoke blocking plate on both sides of the top surface 12a, which can prevent the oil fume from escaping through the suction port group on the top plate 12 and ensure the suction effect of the oil fume. The front side edge, the right side edge, and the right side edge of the bottom surface 12d are used for connecting the shell of the smoke machine, so as to ensure the appearance of the top plate 12 of the smoke machine.

[0034] As shown in the smoke machine of the utility model, Figure 2 As shown, the first suction port 111 is a hidden suction port, the front panel 11 is provided with a gap, the lower edge of the gap extends into the smoke collecting cavity and is provided with a shielding plate 112, the shielding plate 112 is arranged from bottom to top and is inclined rearward, the height of the upper edge of the shielding plate 112 is not lower than the height of the upper edge of the gap, and the gap between the upper edge of the shielding plate 112 and the upper edge of the gap forms the first suction port 111. The smoke machine of the utility model, the projection of the gap falls into the shielding plate 112, and when viewed from the front panel 11 on the user side, the user can see the shielding plate 112 and cannot see the back plate of the smoke collecting cavity through the gap, so that the user cannot see the oil stains on the back plate of the smoke collecting cavity, the appearance of the smoke machine can be ensured, and the user experience is improved.

[0035] In the smoke machine of the utility model, the shielding plate 112 extends from the lower edge of the gap to the inner side of the gap, the distance between the shielding plate 112 and the front panel 11 increases from the lower edge to the upper edge, a flow passage is formed between the shielding plate 112 and the flow cross section of the gap, the flow passage communicates the gap and the first suction port 111, airflow flows into the gap, first hits the shielding plate 112, then flows along the flow passage to the first suction port 111, and then flows into the smoke collecting cavity through the first suction port 111.

[0036] When the user looks at the gap on the front panel 11, the shielding plate 112 can block the user's view to prevent the user from directly seeing the back plate of the smoke collection cavity through the gap, so as to avoid affecting the user's visual perception of the range hood. Since the shielding plate 112 is inclined from bottom to top and rearward, the gap between the upper edge of the shielding plate 112 and the upper edge of the air inlet forms a hidden first air inlet 111. After the oil fume flows into the gap and hits the shielding plate 112, the oil fume can continue to flow into the smoke collection cavity upward through the first air inlet 111, so that the shielding plate 112 does not affect the process of the oil fume flowing into the smoke collection cavity, and the oil fume suction effect of the range hood is ensured.

[0037] The range hood of the utility model, the two sides of the shielding plate 112 have the connecting plates 113, the connecting plates 113 are connected with the side edges of the corresponding sides of the gap, the connecting plates 113 are arc-shaped, and the upper edges of the connecting plates 113 are first arc-shaped edges that protrude in the direction away from the user side. The number of the connecting plates 113 is two, and the two connecting plates 113 are arranged at the two ends of the shielding plate 112 respectively. Each connecting plate 113 connects the end side of the shielding plate 112 with the side edge of the gap, so that the shielding plate 112 and the front panel 11 are connected as a whole in the visual perception, the appearance integrity of the range hood is improved, and the connecting position of the shielding plate 112 and the front panel 11 is increased, so that the connecting stability of the shielding plate 112 and the front panel 11 is improved. One side of the connecting plate 113 close to the gap is a concave arc surface, and the upper edge of the connecting plate 113 forms a concave arc edge, so that the spacing between the upper edge of the connecting plate 113 and the upper edge of the gap is increased as much as possible, the flow area of the first air inlet 111 is increased, and the air inlet amount of the first air inlet 111 is improved.

[0038] The shielding plate 112 and the connecting plate 113 are integrally formed with the front panel 11. The front panel 11 is a sheet metal part, the shielding plate 112 and the connecting plate 113 are both cut and punched on the front panel 11, the connecting position of the connecting plate 113, the front panel 11 and the shielding plate 112 is smoothly transitioned, and the appearance of the front panel 11 is ensured. In addition, since the connecting position of the connecting plate 113, the front panel 11 and the shielding plate 112 is smoothly transitioned, the oil stains are easily cleaned after being attached to the shielding plate 112 and the connecting plate 113.
