[0037] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] like Figure 1 and Figure 2 As shown, this embodiment provides a smoke collecting structure, which includes a smoke collecting hood 1 and an air guide plate 2 rotatably connected to the smoke collecting hood 1. The smoke collecting hood 1 has a smoke collecting chamber 11, and the air guide plate 2 guides the oil smoke generated by cooking into the smoke collecting chamber 11. The smoke collecting hood 1 includes a main hood body 12 and two side panels 13 connected to both sides of the main hood body 12. The main hood body 12 includes a smoke collecting hood bottom plate 121 and a front side plate 122 that are integrally formed and connected. The smoke collecting hood bottom plate 121 is provided with a smoke inlet 1211. The smoke collecting hood bottom plate 121 can be tilted or horizontally set, which is not limited to the drawings of this embodiment.

[0039] The smoke collecting structure also includes a driving assembly 3 disposed in the smoke collecting chamber 11, and the driving assembly 3 includes a mounting bracket 31 and a driving member 32. The driving member 32 is detachably connected to the mounting bracket 31, and the output end of the driving member 32 is connected to the moving member to drive the moving member to move. The driving member 32 can be a driving motor or a driving cylinder, both of which can be used as a power source to drive the moving member to move. The moving member can be an air guide plate 2 or other structural member that needs to be driven by a power source to generate movement, and this embodiment does not make specific restrictions.

[0040] The first end of the mounting bracket 31 is detachably connected to the bottom plate 121 of the smoke hood, and the second end of the mounting bracket 31 is detachably connected to the side plate 13. In this way, the mounting bracket 31 forms a two-point installation in the smoke hood 1, with good installation stability and is not easy to vibrate. Moreover, this two-point installation structure allows the force formed by the mounting bracket 31 to be dispersed to the bottom plate 121 of the smoke hood and the side plate 13, avoiding excessive force on the bottom plate 121 of the smoke hood and the side plate 13, which causes structural deformation, and maintains the aesthetic appearance of the smoke hood 1. Moreover, the mounting bracket 31 forms a support between the bottom plate 121 of the smoke hood and the side plate 13, thereby improving the structural strength of the smoke hood 1, and the bottom plate 121 of the smoke hood and the side plate 13 are not easy to vibrate, thereby reducing the vibration noise of the smoke collection structure.

[0041] In one embodiment, the top of the side panel 13 has a flange 131 folded toward the inside of the smoke collecting chamber 11. The flange 131 can not only increase the structural strength of the side panel 13, but also provide an installation reference for the mounting bracket 31. The second end of the mounting bracket 31 is detachably connected to the flange 131. In the vertical direction, the projection of the flange 131 is located inside the smoke collecting hood bottom plate 121, that is, the flange 131 is located directly above the smoke collecting hood bottom plate 121. Therefore, the mounting bracket 31, the side panel 13, the flange 131 and the smoke collecting hood bottom plate 121 form a quadrilateral frame structure with better stability. Moreover, the mounting bracket 31 can extend toward the top of the side panel 13 in the vertical direction, so that the support range of the smoke collecting hood 1 is larger.

[0042] It should be noted that, along the vertical direction, the projection of the second end of the mounting bracket 31 on the smoke hood bottom plate 121 may overlap or not overlap with the first end. When the projection of the second end of the mounting bracket 31 on the smoke hood bottom plate 121 along the vertical direction overlaps with the first end, the mounting bracket 31 is vertically arranged perpendicular to the horizontal plane; when the projection of the second end of the mounting bracket 31 on the smoke hood bottom plate 121 along the vertical direction is staggered with the first end, the mounting bracket 31 is inclined relative to the horizontal plane. Both types of mounting brackets 31 are acceptable, and can be specifically arranged according to the installation position requirements of the drive member 32, and this embodiment does not impose specific restrictions.

[0043] Similarly, along the horizontal direction, the mounting bracket 31 can be arranged parallel to the side plate 13, or can be arranged obliquely relative to the side plate 13, and is not limited to the drawings of this embodiment.

[0044] In one embodiment, the mounting bracket 31 includes a support plate 311 and a first mounting plate 312 and a second mounting plate 313 connected to both ends of the support plate 311. Figure 3 and Figure 4 As shown. The first mounting plate 312 abuts against the side plate 13, and the second mounting plate 313 abuts against the bottom plate 121 of the smoke hood. This surface contact can further improve the installation stability of the mounting bracket 31. The structure of the mounting bracket 31 is relatively simple, which reduces its own weight. In order to improve the convenience of disassembly and assembly of the mounting bracket 31, the first mounting plate 312 and the side plate 13, and the second mounting plate 313 and the bottom plate 121 of the smoke hood can be connected by fasteners such as screws.

[0045] The mounting bracket 31 also includes a plurality of reinforcing flanges 314, which are formed by bending the edges of the support plate 311 and / or the first mounting plate 312 and / or the second mounting plate 313, so that the mounting bracket 31 forms a frame structure. Compared with a flat plate, the mounting bracket 31 of the frame structure has better structural strength and reduces the risk of deformation.

[0046] In one embodiment, taking the moving part as the air guide plate 2 as an example, the driving part 32 is a push rod motor, and the push rod motor includes a guide sleeve 321 and a push rod 322 which is telescopically arranged in the guide sleeve 321. The push rod motor is arranged obliquely, and its guide sleeve 321 is hinged to the mounting bracket 31, and near the second end, the push rod 322 can pass through the smoke hood bottom plate 121 to hinge the air guide plate 2. The guide sleeve 321 can rotate on the mounting bracket 31, and cooperate with the telescopic movement of the push rod 322, so as to drive the air guide plate 2 to rotate. This direct drive method does not require an intermediate transmission part, and the rotation stability of the air guide plate 2 is better.

[0047] The second end of the mounting bracket 31 is provided with a first support 315, which can be formed by extending the support plate 311 and the reinforcing flange 314. The first support 315 has a first receiving groove 3151, and a first mounting axis (not shown in the figure) of the first support 315 is parallel to the rotation axis of the air guide plate 2. The guide sleeve 321 is embedded in the first receiving groove 3151 and is rotatably connected to the first mounting axis. This embodiment does not limit the appearance structure of the first support 315.

[0048] Correspondingly, the air guide plate 2 is provided with a second support 21, the second support 21 has a second receiving groove 211, the second installation axis of the second support 21 is parallel to the rotation axis of the air guide plate 2, and the end of the push rod 322 is embedded in the second receiving groove 211 and is rotatably connected to the second installation axis.

[0049] In order to improve the structural strength of the second support 21, the air guide plate 2 includes a front panel 22 and a bracket plate 23. The front panel 22 is made of glass or stainless steel and has a beautiful appearance; the bracket plate 23 is a sheet metal structure and is connected to the inner side of the front panel 22 facing the smoke collecting chamber 11 by bonding or other means. The bracket plate 23 can not only improve the strength of the front panel 22, but also facilitate the installation of the front panel 22 on the smoke collecting hood 1. The second support 21 can be welded on the inner side of the bracket plate 23 facing the smoke collecting chamber 11.

[0050] The first mounting shaft and the second mounting shaft can be pins, and mounting holes are provided on the first support 315 and the second support 21, and the pins are inserted into the mounting holes. The pin structure makes it easy to install the push rod motor.

[0051] In one embodiment, a through hole 1212 is provided on the smoke hood bottom plate 121, and the output end of the driving member 32 passes through the through hole 1212 to connect to the air guide plate 2. A protective ring 4 is sleeved on the smoke hood bottom plate 121, and the protective ring 4 is embedded in the through hole 1212 to cover the edge of the through hole 1212 to prevent the push rod 322 from scratching the edge of the through hole 1212 during movement and causing damage. The protective ring 4 can be made of elastic materials such as rubber, which is easy to install and has good buffering performance.

[0052] In another embodiment, the driving assembly 3 further includes a connecting rod mechanism 33, the connecting rod mechanism 33 is hinged to the output end of the air guide plate 2 and the driving member 32, and the driving member 32 drives the air guide plate 2 to rotate through the connecting rod mechanism 33. The connecting rod mechanism 33 can extend the driving stroke of the driving member 32, so that the flip angle range of the air guide plate 2 is larger. Moreover, by setting the connecting rod mechanism 33 of different structures as the intermediate transmission member, the position selection of the driving member 32 can be made more flexible, and the space requirement for the smoke collecting chamber 11 can be reduced.

[0053] Taking the double rocker mechanism as an example, the link mechanism 33 includes a first link 331 and a second link 332. One end of the first link 331 is hinged to the smoke hood 1, and one end of the second link 332 is hinged to the air guide plate 2. The output end of the driving member 32 is hinged to the hinge point of the first link 331 and the second link 332 to form a double rocker mechanism. The rotation of the guide sleeve 321 on the mounting bracket 31 cooperates with the telescopic movement of the push rod 322 to drive the first link 331 and the second link 332 to rotate simultaneously, and then the hinge point of the first link 331 and the second link 332 moves to drive the air guide plate 2 to rotate around the rotation axis between it and the smoke hood 1.

[0054] The connecting rod mechanism 33 needs to be located in the same plane as the output end of the driving member 32, so the hinged support 333 of the first connecting rod 331 can be installed on the flange 131 of the side plate 13, and the second connecting rod 332 passes through the through hole 1212 on the bottom plate 121 of the smoke collecting hood and is hinged to the second support 21. Compared with the push rod 322 of the push rod motor, the second connecting rod 332 has a simple structure and a smaller cross-sectional size, and the opening area of ​​the through hole 1212 is smaller to meet the use requirements, thereby reducing the amount of oil smoke entering the smoke collecting chamber 11 through the through hole 1212.

[0055] It should be noted that in the connecting rod mechanism 33 formed by the double rocker mechanism, the first connecting rod 331, the air deflector 2 rotation axis and the air deflector 2 between the second support 21 are two rockers, and the second connecting rod 332, the air deflector 2 rotation axis and the fixed distance between the hinge support 333 are two connecting rods. In practical applications, in order to avoid the double rocker mechanism forming a dead point position causing the air deflector 2 to be unable to open or close, the respective rod lengths of the first connecting rod 331 and the second connecting rod 332, and the position settings of the hinge support 333 and the second support 21 need to meet the following requirements: Among the two rockers and two connecting rods, the sum of the lengths of the shortest rod and the longest rod is less than or equal to the sum of the lengths of the remaining two rods.

[0056] If the above requirements cannot be met due to structural limitations, the double rocker mechanism can be prevented from forming a dead point by controlling the angle between the first connecting rod 331 and the second connecting rod 332, such as Figure 5 and Figure 6As shown in the figure, the angle α is the angle between the first connecting rod 331 and the second connecting rod 332. By setting the parameters of the push rod motor, for example, controlling the stroke of the push rod 322, the angle α can be controlled to be greater than 0° and less than 180°. Figure 5 is a schematic diagram when the air guide plate 2 is closed. Figure 6 It is a schematic diagram when the air guide plate 2 is opened.

[0057] The embodiment of the utility model also provides a range hood, which includes the above-mentioned smoke collecting structure. The smoke collecting structure is installed with a driving member 32 via a mounting bracket 31, and the two ends of the mounting bracket 31 are detachably connected to the smoke collecting hood bottom plate 121 and the side plate 13, respectively, to form a two-point installation, which has good installation stability and disperses the force to the smoke collecting hood bottom plate 121 and the side plate 13, avoiding structural deformation caused by excessive force, and maintaining the aesthetic appearance of the range hood; at the same time, the mounting bracket 31 forms a support between the smoke collecting hood bottom plate 121 and the side plate 13, improving the structural strength of the smoke collecting hood 1, and the smoke collecting hood bottom plate 121 and the side plate 13 are not easy to vibrate, reducing the vibration noise of the smoke collecting structure, and improving the user experience of the range hood.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
