[0045] Embodiment 1

[0046] As shown in Figure 2 and Figure 3 The smoke gathering assembly provided by the utility model is installed on the smoke collecting cover 1, and specifically comprises: an upper baffle 6, a lower baffle 8 and a side baffle 5.

[0047] As shown in Figure 6 The upper baffle 6 and the lower baffle 8 both extend along the left-right direction, and the upper end of the upper baffle 6 is rotatably connected to the smoke collecting cover 1 through a rotating piece, which can be a sixth rotating shaft 4 or a hinge. The lower end of the upper baffle 6 is connected to the upper end of the lower baffle 8 through a second rotating shaft 16, and the included angle between the lower baffle 8 and the upper baffle 6 can be changed, so that the shape of the smoke gathering assembly can be changed.

[0048] As shown in Figure 5 and Figure 6 The smoke gathering assembly has a working state and a storage state, and can be switched between the two. As shown in Figure 6As shown, in the working state, the lower baffle 8 is away from the smoke hood 1 compared to the upper baffle 6, and the lower baffle 8 is closer to the user side, which improves the smoke gathering range in the front-rear direction, and the user can avoid touching the lower baffle 8 through the rotating connection.

[0049] The left and right sides of the upper baffle 6 and the lower baffle 8 are provided with side baffles 5, which can be fixedly connected with the upper baffle 6 or the lower baffle 8. In this embodiment, the two side baffles 5 are fixedly connected to the left and right ends of the lower baffle 8.

[0050] The side baffle 5 is along the front-rear direction, which includes a first upper edge and a first lower edge arranged at an angle or an elongated line arranged at an angle. In this embodiment, the first upper edge and the first lower edge are directly connected and arranged at an angle. In other implementable schemes, the first upper edge and the first lower edge can also not be directly connected, and the two are connected through a transition edge. At this time, the elongated lines of the two are arranged at an angle.

[0051] The first lower edge and the lower baffle 8 can be fixedly connected through welding, threaded fasteners or adhesion.

[0052] When the smoke gathering device is in the working state, the first upper edge abuts against the back of the upper baffle 6, avoiding the leakage of oil fume from between the side baffle 5 and the upper baffle 6, so as to enclose the smoke gathering cavity by the upper baffle 6, the lower baffle 8 and the side baffle 5.

[0053] When the range hood is working, the smoke gathering assembly is rotated to the working state, and the upper baffle 6, the lower baffle 8 and the side baffle 5 can enclose the smoke gathering cavity to realize smoke gathering from the left-right direction, the upper direction and the front direction, and the smoke gathering coverage is larger. The smoke gathering cavity is only open at the bottom, and it is difficult for oil fume to escape after entering the smoke gathering cavity through the open structure. Compared with the prior art, the upper baffle 6 extends to the front side of the smoke hood 1 by a certain distance, which increases the distance between the lower baffle 8 and the front end face 18 of the smoke hood 1, improves the smoke gathering range of the smoke gathering assembly in the front-rear direction, improves the smoke gathering capacity of the range hood, and reduces the escape of oil fume.

[0054] The smoke gathering assembly provided in this embodiment can especially improve the problem of more oil fume escaping instantaneously during Chinese cooking and frying, and bring more comfortable cooking experience to the user.

[0055] The angle of the first upper edge and the first lower edge towards the side of the smoke hood 1 or the angle of the elongated lines of the first upper edge and the first lower edge towards the side of the smoke hood 1 is in the range of 70°≤A≤180°.

[0056] This angle is the angle of the upper baffle 6 and the lower baffle 8 towards the side of the smoke hood 1 in the working state. For example, Figure 4As shown, in this embodiment, the included angle is 90°, so that the upper baffle 6 can be arranged in the horizontal direction and the lower baffle 8 can be arranged in the vertical direction when the smoke gathering assembly is in the working state.

[0057] The side baffles are integrally formed, that is, the two side baffles on the left and right sides of the smoke gathering assembly are formed by one plate body, which is simple in structure and easy to install.

[0058] Generally, as Figure 4 As shown, the smoke collecting cover 1 can be provided with a hanging cabinet 11. When the upper baffle 6 is rotated away from the smoke collecting cover 1 to the working state, the upper baffle 6 is parallel to the lower surface of the hanging cabinet 11, so that the upper baffle 6 is attached to the hanging cabinet 11 to prevent oil fume from entering. The lower baffle 8 is arranged in the vertical plane and in the front-rear direction, and can be arranged flush with the hanging cabinet door 10 above the smoke collecting cover 1, so that the lower baffle 8 and the hanging cabinet door 10 form an integrated combination, which is visually beautiful and neat.

[0059] In addition, a control assembly can be arranged on the outer surface of the lower baffle 8. The control assembly can be a key type or a touch screen type. When the smoke gathering assembly is in the working state, the control assembly is also lifted and moved forward with the lower baffle 8, which shortens the control distance of the user and harmonizes with the visual angle of the user, thereby improving the user experience.

[0060] As shown, Figure 7 As shown, a notch can be arranged at the top rear corner of the side baffle 5 to avoid interference with the notch of the rotating member when the smoke gathering assembly is in the working state, so that the smoke gathering assembly can be rotated to the working state with the maximum shielding range of the side baffle 5.

[0061] As shown, Figure 5 As shown, when the smoke gathering assembly is switched from the working state to the storage state, the upper baffle 6 and the lower baffle 8 are located in the same plane, which is convenient for wiping and cleaning. In addition, the upper baffle 6 and the lower baffle 8 connected in one plane shield the smoke inlet of the smoke collecting cover 1.

[0062] The size of the plane where the upper baffle 6 and the lower baffle 8 are connected depends on the size of the smoke inlet. When the smoke inlet occupies the entire front end surface 18 of the smoke collecting cover 1, the plane where the upper baffle 6 and the lower baffle 8 are connected can completely cover the front end surface 18 of the smoke collecting cover 1.

[0063] In other possible implementations, a first sealing element is provided on the contact surface of at least one of the first lower edge and the lower baffle 8. Specifically, the first sealing element can be provided on the back of the lower baffle 8. The first sealing element can be a sealing groove. When the first lower edge is inserted into the sealing groove, a seal can be formed between the first lower edge and the lower baffle 8, reducing oil fume leakage. Similarly, a second sealing element is provided on the contact surface of at least one of the first upper edge and the upper baffle 6. Specifically, a second sealing element can be provided on the back of the upper baffle 6. The second sealing element can be a sealing groove. When the first upper edge is inserted into the sealing groove, a seal can be formed between the first upper edge and the upper baffle 6, reducing oil fume leakage.

[0064] Example 2

[0065] like Figure 9 - Figure 12 As shown, the difference from Embodiment 1 is that in this embodiment, the first upper edge is fixedly connected to the upper baffle 6, and when the smoke collection device is in working condition, the first lower edge abuts against the back of the lower baffle 8, as shown. Figure 10 As shown. The first upper edge and the upper baffle 6 can be connected by welding, threaded parts or adhesive.

[0066] In this embodiment, the drive mechanism that drives the smoke collection assembly to change its shape can be connected to the upper baffle 6. An elastic reset member can be provided between the upper baffle 6 and the lower baffle 8. The elastic reset member is used to make the lower baffle 8 tend to swing towards the smoke collection hood 1, so that the lower baffle 8 is tightly pressed against the side baffle 5 under the action of the elastic reset member, achieving a better sealing effect. The upper baffle 6 and the lower baffle 8 are rotatably connected by a second rotating shaft 16. The elastic reset member can be a torsion spring 19, which is sleeved on the second rotating shaft 16. Figure 10 As shown. One end of the torsion spring is connected to the upper baffle 6, and the other end is connected to the lower baffle 8, as shown. Figure 13 As shown.

[0067] Example 3

[0068] The smoke collection device provided by this utility model includes a smoke collection hood 1, a drive mechanism, and the aforementioned smoke collection component; the smoke collection component is rotatably connected to the smoke collection hood 1; the drive mechanism is connected to the smoke collection hood 1, and the drive end of the drive mechanism is movably connected to the smoke collection component to drive the smoke collection component to rotate relative to the smoke collection hood 1 to the working state.

[0069] like Figure 7As shown, the driving mechanism can include a telescopic module 3, for example, a push rod motor. The driving end of the driving mechanism can be movably connected with the upper baffle 6, the lower baffle 8 or the side baffle 5, when driving one of them to move, the other two can move together under the push of the side baffle 5 to realize the switching between the working state and the storage state. When the upper baffle 6 changes from the storage state to the working state, the driving mechanism pushes the upper baffle 6 and the lower baffle 8 to move forward and upward, the upper baffle 6 rotates a certain angle relative to the smoke hood 1, the lower baffle 8 rotates a certain angle relative to the upper baffle 6, the distance between the first upper edge of the side baffle 5 and the upper baffle 6 becomes closer and closer, until the upper baffle 6 contacts and fits with the first upper edge of the side baffle 5, at this time the upper baffle 6 rotates away from the smoke hood 1 to the working state, the upper baffle 6, the lower baffle 8, the side baffle 5 and the smoke hood 1 can be arranged to form a smoke gathering cavity.

[0070] Specifically, in the embodiment, the smoke gathering assembly adopts the arrangement mode in the embodiment 1, and the driving end of the driving mechanism is movably connected with the side baffle 5.

[0071] Specifically, as shown in the drawings, Figure 6 As shown, the side baffle 5 is provided with an arc-shaped sliding groove 17, and the driving end of the driving mechanism has a first rotating shaft 15, which is slidingly connected in the arc-shaped sliding groove 17.

[0073] Specifically, when the upper baffle 6 is converted between the storage state and the working state, the telescopic module 3 can drive the upper baffle 6 and the lower baffle 8 to move. The telescopic module 3 is fixedly arranged on the inner side wall of the smoke hood 1. One end of the connecting piece 12 is rotatably connected with the top of the inner side wall of the smoke hood 1, the middle part of the connecting piece 12 is rotatably connected with one end of the telescopic module 3, one end of the telescopic module 3 can be telescopic, the other end of the connecting piece 12 is rotatably connected with the arc-shaped sliding groove 17 through the first rotating shaft 15, and the first rotating shaft 15 can slide along the arc-shaped sliding groove 17. When the upper baffle 6 changes from the storage state to the working state, one end of the telescopic module 3 is elongated upward and forward, one end of the connecting piece 12 rotates relative to the inner side wall of the smoke hood 1, the middle part of the connecting piece 12 rotates relative to one end of the telescopic module 3, the first rotating shaft 15 rotates around the axis of the first rotating shaft 15 relative to the arc-shaped sliding groove 17, and the first rotating shaft 15 slides along the arc-shaped sliding groove 17, so that the telescopic module 3 pushes the upper baffle 6 and the lower baffle 8 to move forward and upward, and finally the upper baffle 6 is in a horizontal state and the lower baffle 8 is in a vertical state.

[0074] The above arrangement utilizes the connection relationship among the connecting piece 12, the smoke collecting hood 1 and the smoke gathering assembly, and only one telescopic module 3 can realize the deformation of the smoke gathering assembly, which is low in cost.

[0075] Further, when the upper baffle 6 rotates away from the smoke collecting hood 1 to the working state, the side baffle 5 can shield the telescopic module 3, the oil screen and the cavity structure inside the smoke collecting hood 1, etc., to protect the telescopic module 3, the oil screen and the cavity structure inside the smoke collecting hood 1, etc., and make the whole range hood more beautiful and tidy.

[0076] Further, as shown in Figure 6 and Figure 7 , the connecting piece 12 comprises a first connecting structure 121 and a second connecting structure 122; the first connecting structure 121 and the second connecting structure 122 are arranged obliquely; one end of the first connecting structure 121 is rotationally connected with the inner side wall of the smoke collecting hood 1; the other end of the first connecting structure 121 is connected with one end of the second connecting structure 122, and the connection area of the first connecting structure 121 and the second connecting structure 122 is rotationally connected with one end of the telescopic module 3; the other end of the second connecting structure 122 is rotationally connected with the sliding groove 17 through the first rotation shaft 15.

[0078] In this embodiment, the first connecting structure 121 and the second connecting structure 122 are both rod-shaped. The included angle between the axis of the first connecting structure 121 and the axis of the second connecting structure 122 is obtuse.

[0079] When the upper baffle 6 changes from the storage state to the working state, one end of the telescopic module 3 is elongated upward and forward, the first connecting structure 121 rotates upward around the axis of the third rotation shaft 13, drives the second connecting structure 122 to move upward, and further drives the side baffle 5 to move upward and the lower baffle 8 to rotate relative to the upper baffle 6, and the upper baffle 6 rotates relative to the smoke collecting hood 1, until the upper baffle 6, the lower baffle 8, the side baffle 5 and the smoke collecting hood 1 can be arranged to form the smoke gathering cavity.
