[0038] References to "embodiments" or "implementations" herein mean that a particular feature, structure, or characteristic described in conjunction with the embodiments or implementations may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] Range hoods have become one of the essential appliances in modern family kitchens. As the application rate of range hoods increases, people pay more and more attention to the fume extraction effect and installation aesthetics of range hoods. At present, in order to have a larger suction area, the suction part of the range hood in the relevant technology is set larger, but the current suction part is fixed, which makes the overall structure of the range hood larger.

[0040] In view of this, the present embodiment provides a range hood 100. The range hood 100 can reduce the volume of the range hood 100.

[0041] See also Figure 1 , a range hood 100, comprising: a smoke hood 10, a plurality of smoke collecting components 20;

[0042] The smoke collecting assembly 20 comprises: a smoke collecting member 21, a rotating member 22, a driving member 23, and a crossbar 24;

[0043] The cross bar 24 is arranged in the smoke collecting hood 10, one side of the rotating member 22 is movably connected to the cross bar 24, the other side of the rotating member 22 is movably connected to the smoke collecting member 21, and the side of the smoke collecting member 21 away from the rotating member 22 is connected to the smoke collecting hood 10; the driving member 23 is rotatably connected to the smoke collecting member 21, and the driving member 23 is used to drive the smoke collecting member 21 to rotate, so that the smoke collecting member 21 and the rotating member 22 form a first angle α.

[0044] The above-mentioned range hood 100 is provided with a cross bar 24 in the smoke collecting hood 10, which is connected to the cross bar 24 through a rotating member 22, and the rotating member 22 and the smoke collecting member 21 are movably connected. In addition, a driving member 23 is provided in the smoke collecting hood 10, and the smoke collecting member 21 is driven to open by the driving member 23. After the smoke collecting member 21 is opened, the smoke collecting member 21 is located outside the smoke collecting hood 10 and forms a first angle α with the rotating member 22, so that the range hood 100 has a larger smoke collecting area. When not in use, the smoke collecting member 21 is located in the smoke collecting hood 10 and becomes one with the smoke collecting hood 10, so that the volume of the range hood 100 when not in use can be reduced, thereby reducing the overall structure of the range hood 100.

[0045] It can be understood that the smoke collecting assembly 20 is arranged in the smoke hood 10, and multiple smoke collecting assemblies 20 can be arranged. In the present embodiment, two smoke collecting assemblies 20 are arranged, which are arranged on the left and right sides of the smoke hood 10 respectively; a cross bar 24 is arranged in the smoke hood 10, and the cross bar 24 is arranged in the middle position of the bottom of the smoke hood 10, and is sandwiched between the two smoke collecting parts 21. The cross bar 24 is rotatably connected with the rotating part 22, and the smoke collecting part 21 is rotatably connected with the cross bar 24. A driving part 23 is also arranged in the smoke collecting part 21, and the driving part 23 is movably connected with the smoke collecting part 21, so that the smoke collecting part 21 can be driven to rotate by the driving part 23, so that the smoke collecting part 21 is opened and located outside the smoke hood 10, so that the range hood 100 can have a larger smoke inlet and a larger smoke suction area when sucking smoke.

[0046] When the smoke collecting member 21 is unfolded, the rotating member 22 is driven by the smoke collecting member 21 to rotate and forms a first angle α with the smoke collecting member 21. At this time, the rotating member 22 and the smoke collecting member 21 face in opposite directions. The smoke collecting member 21 faces Figure 1As shown on the left side, the rotating member 22 is oriented as shown in FIG. Figure 1 As shown on the right side, an oil fume outlet is provided on the rotating member 22; the area of ​​oil fume that can be extracted by the rotating member 22 plus the area of ​​oil fume that can be extracted by the smoke collecting member 21 is the area of ​​oil fume that can be extracted by the range hood 100; the smoke collecting outlets on the rotating member 22 and the smoke collecting member 21 are both arranged inclined in the horizontal direction; compared with the traditional range hood 100 with the smoke inlet perpendicular to the ground, the range of oil fume that can be absorbed by the range hood 100 in this embodiment is larger, and the range hood 100 also has a smaller volume when not in use.

[0047] See also Figure 1 In some embodiments, the first angle α ranges from 100° to 140°.

[0048] It can be understood that the rotating member 22 and the smoke collecting member 21 form a first angle α, and the angle of the first angle α can be 100°~140°. Specifically, the first angle α can be 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140° and other angles. Preferably, the first angle α is 120°.

[0049] When the first angle α is smaller, the angle between the oil smoke outlet on the rotating member 22 and the smoke inlet on the smoke collecting member 21 in the horizontal direction becomes larger, so that the negative pressure space generated by the range hood 100 will be farther away from the oil smoke, making the oil smoke absorption effect of the range hood 100 worse.

[0050] When the first angle α is larger, the angle between the oil smoke outlet on the rotating part 22 and the smoke inlet on the smoke collecting part 21 and the horizontal direction will be smaller, so that the range hood 100 will be like a traditional range hood 100, with the air intake perpendicular to the horizontal direction, which makes the oil smoke suction area of ​​the range hood 100 smaller.

[0051] Therefore, as a preferred angle, the first angle α is set to 120° so that the range hood 100 can have a better fume absorbing effect while having a larger smoke collecting area.

[0052] See also Figure 2 In some embodiments, the smoke collecting member 21 includes: a first guide plate 211, a second guide plate 212, a third guide plate 213 and a fourth guide plate 214;

[0053] The first guide plate 211 and the second guide plate 212 are spaced apart from each other, the third guide plate 213 and the fourth guide plate 214 are provided with a second included angle, and the third guide plate 213 and the fourth guide plate 214 are sandwiched between the first guide plate 211 and the second guide plate 212 .

[0054] It can be understood that the smoke collecting member 21 includes: a first guide plate 211, a second guide plate 212, a third guide plate 213, and a fourth guide plate 214. The cross-sections of the third guide plate 213 and the fourth guide plate 214 are triangular, wherein the first guide plate 211 and the second guide plate 212 are arranged along the Figure 1 The third guide plate 213 and the fourth guide plate 214 are arranged in sequence in the front and rear directions as shown in FIG. Figure 2 The third guide plate 213 and the fourth guide plate 214 are sandwiched between the first guide plate 211 and the second guide plate 212, and an angle (such as Figure 5 As shown), therefore, the third guide plate 213 and the fourth guide plate 214 form an angle with the horizontal direction of the range hood 100; when the smoke collecting piece 21 is in the open state, the smoke collecting piece 21 is located outside the smoke hood 10, at this time, there is an angle between the fourth guide plate 214 and the horizontal plane, and when the smoke collecting piece 21 is in the closed state, the smoke collecting piece 21 is located inside the smoke hood 10, at this time, the fourth guide plate 214 is perpendicular to the horizontal plane.

[0055] See also Figures 2 to 4 In some embodiments, a limiting member 215 is provided on a side of the third guide plate 213 away from the rotating member 22 , and the limiting member 215 is used to limit the rotating position of the smoke collecting member 21 .

[0056] It can be understood that the limit member 215 is arranged on the side away from the rotating member 22. The limit member 215 can be set to a baffle structure, located on the side of the third guide plate 213 away from the rotating member 22. The limit member 215 is used to limit the maximum rotation angle of the smoke collecting member 21 during the rotation process. The limit member 215 can rotate with the smoke collecting member 21. When the smoke collecting member 21 rotates to the maximum preset position, the limit member 215 abuts against the third guide plate 213, which can limit the rotation of the third guide plate 213, thereby achieving the purpose of limiting, so that the range hood 100 has a greater smoking efficiency while having a larger smoking area.

[0057] See also Figure 5 , in some embodiments, further comprising: a pull rod 30, a first baffle 40;

[0058] The fourth guide plate 214 is provided with a first smoke inlet 216, and a first baffle 40 is provided on the fourth guide plate 214, and the first baffle 40 covers the first smoke inlet 216; wherein, one side of the first baffle 40 is movably arranged on a side of the smoke collecting member 21 away from the driving member 23, one end of the pull rod 30 is rotatably connected to the rotating member 22, and the other end of the pull rod 30 is rotatably connected to the first baffle 40; when the driving member 23 drives the smoke collecting member 21 to open, the pull rod 30 drives the first baffle 40 to move, so that the first smoke inlet 216 is opened.

[0059] It can be understood that a first smoke inlet 216 is arranged on the fourth guide plate 214, and a first baffle 40 is arranged on the first smoke inlet 216, and the first baffle 40 covers the smoke inlet. In order to open the first smoke inlet 216 when needed, the first baffle 40 is movably arranged on the side of the fourth guide plate 214 away from the driving member 23, and a movably arranged pull rod 30 is arranged on the side of the fourth guide plate 214 close to the driving member 23; the other end of the pull rod 30 is arranged on the smoke collecting member 21, so that the pull rod 30 can rotate with the fourth guide plate 214 and the smoke collecting member 21.

[0060] It can be understood that when the driving member 23 drives the smoke collecting member 21 to unfold, the smoke collecting member 21 rotates around the end of the rotating member 22 away from the cross bar 24. Since the smoke collecting member 21 and the rotating member 22 are rotatably connected, the rotation of the smoke collecting member 21 will also drive the rotating member 22 to rotate. When the rotating member 22 rotates, the first baffle 40 also rotates with the rotating member 22. Therefore, the relative position of the first baffle 40 also changes, but the pull rod 30 is movably connected to the first baffle 40. When the first baffle 40 rotates, the first baffle 40 is pulled up by the pull rod 30, so that the first baffle 40 is away from the first smoke inlet 216, and the first smoke inlet 216 is opened.

[0061] See also Figure 6 In some embodiments, the rotating member 22 includes a first connecting plate 221, a second connecting plate 222, and a third connecting plate 223;

[0062] The first connecting plate 221 and the third connecting plate 223 are vertically and spaced apart on both sides of the second connecting plate 222 , and a second smoke inlet 224 is disposed on the first connecting plate 221 .

[0063] It can be understood that the rotating member 22 includes a first connecting plate 221, a second connecting plate 222, and a third connecting plate 223, wherein the first connecting plate 221 and the third connecting plate 223 are vertically arranged on the second connecting plate 222, and the first connecting plate 221 and the third connecting plate 223 are arranged with the second connecting plate 222 spaced apart;

[0064] The first connecting plate 221 and the third connecting plate 223 are disposed on both sides of the second connecting plate 222 so that the interior of the smoke hood 10 is a complete cavity when the smoke hood 10 is unfolded, thereby preventing the smoke from leaking out after entering the smoke hood 10 .

[0065] See also Figure 5 , in some embodiments, further comprising: a first connecting rod 50, a second connecting rod 60, and a second baffle 70;

[0066] A second baffle 70 covering the second smoke inlet 224 is provided on the first connecting plate 221, the first connecting rod 50 and the second connecting rod 60 are both connected to the pull rod 30, and the end of the first connecting rod 50 away from the pull rod 30 and the end of the second connecting rod 60 away from the pull rod 30 are both connected to the second baffle 70; wherein the length of the first connecting rod 50 is less than the length of the second connecting rod 60.

[0067] It can be understood that a second smoke inlet 224 is provided on the first connecting plate 221. In order to close the second smoke inlet 224 when the range hood 100 is not in use, a second baffle 70 is provided on the first connecting plate 221, and the second baffle 70 covers the second smoke inlet 224. A first connecting rod 50 and a second connecting rod 60 are respectively provided on both sides of the second baffle 70. The end of the first connecting rod 50 away from the second baffle 70 is connected to the pull rod 30, and the end of the second connecting rod 60 away from the second baffle 70 is connected to the pull rod 30. The two ends of the first connecting rod 50 and the second connecting rod 60 are movably connected to the pull rod 30 and the second baffle 70 respectively. In this way, when the first connecting rod 50 and the second connecting rod 60 move, the second baffle 70 moves with the first connecting rod 50 and the second connecting rod 60 to open the second smoke inlet 224. In this way, oil smoke can enter the smoke hood 10 through the second smoke inlet 224.

[0068] It can be understood that since the pull rod 30 is parallel to the horizontal plane when the smoke collecting piece 21 is unfolded, in order to enable the second baffle 70 to be opened, the length of the first connecting rod 50 is set to be smaller than the length of the second connecting rod 60. In this way, when the smoke collecting piece 21 is opened, the second baffle 70 can also be opened by the first connecting rod 50 and the second connecting rod 60. In this way, the oil smoke can enter the smoke hood 10 through the second smoke inlet 224 and be discharged.
