Description

Technical Field

[0001] This utility model relates to the field of smoke machine technology, and in particular to a fan device and a smoke machine. Background Technology

[0002] A range hood, also known as a cooking hood or range extractor, is a kitchen appliance used to purify the kitchen environment. Installed above the stove, it quickly removes cooking fumes and harmful oil fumes from the stove, venting them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions. The range hood contains a fan that rotates at high speed, generating a powerful airflow to extract the cooking fumes.

[0003] In related technologies, the location of the public flue in different kitchen environments varies, and the current installation method of the range hood can only be adapted and connected to a public flue in a single direction. This cannot meet the smoke exhaust needs of the range hood in different spaces and environments. If the range hood needs to be connected to public flues in different directions, the structure of the range hood fan needs to be significantly modified, which is costly. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a fan device for a range hood, wherein the orientation of the smoke outlet of the fan device is adjustable.

[0005] Another objective of this utility model is to provide a smoke hood.

[0006] The fan device of the range hood according to an embodiment of the present utility model includes: a mounting bracket assembly defining a fan installation area, the mounting bracket assembly having clearance notches on both the left and right sides; a fan body having a smoke outlet connector on one side in the left-right direction, the fan body being disposed in the fan installation area, and selectively connecting the smoke outlet connector to the clearance notches on the left or right sides of the mounting bracket assembly to adjust the orientation of the smoke outlet connector. Therefore, by placing the fan body within the fan installation area and selectively connecting the smoke outlet connector to the clearance notch on the left or right side of the mounting bracket assembly, the orientation of the smoke outlet can be selectively adjusted according to the actual installation scenario of the range hood, thus meeting the smoke exhaust requirements of the range hood in different spaces and environments. In some examples of this utility model, the mounting bracket assembly includes a first mounting bracket assembly and a second mounting bracket assembly. The first mounting bracket assembly and the second mounting bracket assembly are spaced apart on the left and right and define the fan mounting area. Both the first mounting bracket assembly and the second mounting bracket assembly are provided with the avoidance notch.

[0007] In some examples of this utility model, both the first mounting bracket assembly and the second mounting bracket assembly include a first bracket and a second bracket. The first bracket extends vertically, and the second bracket extends horizontally and is connected to the first bracket. The first bracket is used to connect to the mounting wall, and the second bracket is used to support the fan body. The clearance notch is provided on the second bracket on both sides.

[0008] In some examples of this utility model, the cross-section of the second bracket is L-shaped, including a third limiting plate and a fourth limiting plate that are perpendicular to each other. The third limiting plates of the two second brackets are arranged opposite to each other to limit the fan body to the left and right sides of the wall. The fourth limiting plates of the two second brackets are used to support the fan body. The clearance notch is provided on the third limiting plates of the second brackets on both sides.

[0009] In some examples of this utility model, the cross-section of the first bracket is L-shaped, including a first limiting plate and a second limiting plate that are perpendicular to each other. The second limiting plates of the two first brackets are arranged opposite to each other to limit the fan body to the left and right sides of the wall. The first limiting plates of the two first brackets are arranged to the front to limit the fan body to the rear side of the wall.

[0010] In some examples of this utility model, both the first mounting bracket assembly and the second mounting bracket assembly include a third bracket, one end of which is connected to the first bracket and the other end of which is connected to the second bracket.

[0011] In some examples of this utility model, a fourth bracket is also included, which is connected to the first mounting bracket assembly and the second mounting bracket assembly. The fourth bracket has a first connection position at both ends and two second connection positions between the two first connection positions. The first connection position or the second connection position of the fourth bracket is connected to the first mounting bracket assembly and the second mounting bracket assembly to adjust its connection position with the first mounting bracket assembly and the second mounting bracket assembly.

[0012] In some examples of this utility model, the distance between the surface of the fan body with the smoke outlet connector and the surface parallel to that surface is defined as the width, and the distance between the other two surfaces is defined as the depth. When the first connecting position of the fourth bracket connects the first mounting bracket assembly and the second mounting bracket assembly, the distance between the first mounting bracket assembly and the second mounting bracket assembly is adapted to the width of the fan body, and the smoke outlet connector faces the left or right side. When the second connecting position of the fourth bracket connects the first mounting bracket assembly and the second mounting bracket assembly, the distance between the first mounting bracket assembly and the second mounting bracket assembly is adapted to the depth of the fan body, and the smoke outlet connector faces the front or rear side.

[0018] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0019] The following is for reference. Figures 1-8 The present invention describes a fan device 100 for a range hood 1000 according to an embodiment of the present invention. The fan device 100 can be applied to the range hood 1000.

[0020] Combination Figures 1-8 As shown, the fan device 100 of the smoke hood 1000 according to this utility model can mainly include: a mounting bracket assembly 10 and a fan body 20.

[0021] The mounting bracket assembly 10 defines the fan installation area 103. The mounting bracket assembly 10 has clearance notches 124 on both the left and right sides. The fan body 20 has a smoke outlet connector 29 on one side in the left or right direction. The fan body 20 is located in the fan installation area 103, and the smoke outlet connector 29 is selectively connected to the clearance notches 124 on the left or right side of the mounting bracket assembly 10 to adjust the orientation of the smoke outlet connector 29. Specifically, during the connection and fixing of the fan body 20 and the mounting bracket assembly 10, since the mounting bracket assembly 10 has clearance notches 124 on both the left and right sides, by placing the fan body 20 within the fan installation area 103 and connecting the smoke outlet connector 29 into the clearance notch 124 on either the left or right side of the mounting bracket assembly 10, the orientation of the smoke outlet connector 29 can be selectively directed to the left or right. When the kitchen's common flue is on the left, the position of the fan body 20 relative to the mounting bracket assembly 10 can be adjusted so that the smoke outlet connector 29 connects to the clearance notch 124 on the left side of the mounting bracket assembly 10, thereby connecting the smoke outlet connector 29 to the common flue on the left. When the kitchen's common flue is on the right, the position of the fan body 20 relative to the mounting bracket assembly 10 can be adjusted so that the smoke outlet connector 29 connects to the clearance notch 124 on the right side of the mounting bracket assembly 10, thereby connecting the smoke outlet connector 29 to the common flue on the right.

[0022] With this setup, only the relative position of the fan body 20 to the mounting bracket assembly 10 needs to be adjusted to make the smoke outlet connector 29 compatible with the public flue located on the left or right side in different kitchen environments. This not only meets the smoke exhaust requirements of the range hood 1000 in different spaces and environments, but also eliminates the need for significant changes to the structure of the fan device 100 of the range hood 1000. This improves the adaptability of the fan device 100 of the range hood 1000 and reduces the cost of adjusting the orientation of the smoke outlet connector 29 of the fan device 1000.

[0023] Combination Figures 2-7 As shown, the mounting bracket assembly 10 includes a first mounting bracket assembly 101 and a second mounting bracket assembly 102. The first mounting bracket assembly 101 and the second mounting bracket assembly 102 are spaced apart on the left and right and define the fan mounting area 103. Both the first mounting bracket assembly 101 and the second mounting bracket assembly 102 are provided with avoidance notches 124.

[0024] Specifically, by arranging the first mounting bracket assembly 101 and the second mounting bracket assembly 102 at intervals in the left-right direction, and defining a fan installation area 103 between the first mounting bracket assembly 101 and the second mounting bracket assembly 102, the fan body 20 can be placed between the first mounting bracket assembly 101 and the second mounting bracket assembly 102, thus placing the fan body 20 in the fan installation area 103. By providing clearance notches 124 on both the first mounting bracket assembly 101 and the second mounting bracket assembly 102, when adjusting the orientation of the smoke outlet connector 29 of the fan body 20, it is only necessary to manually rotate the fan body 20, and selectively connect the smoke outlet connector 29 to the clearance notch 124 of the first mounting bracket assembly 101 or the second mounting bracket assembly 102, thereby enabling the smoke outlet connector 29 to connect with the common flue on the left or the common flue on the right.

[0025] Combination Figures 2-7 As shown, both the first mounting bracket assembly 101 and the second mounting bracket assembly 102 include a first bracket 11 and a second bracket 12. The first bracket 11 extends vertically, and the second bracket 12 extends horizontally and is connected to the first bracket 11. The first bracket 11 is used to connect to the mounting wall, and the second bracket 12 is used to support the fan body 20. The clearance notch 124 is provided on the second bracket 12 on both sides.

[0026] Specifically, by extending the first bracket 11 vertically and connecting it to the mounting wall, after the fan body 20 is installed in the fan installation area 103, it can be fixed by connecting the first bracket 11 to the mounting wall, so that the fan device 100 can be installed in the kitchen.

[0027] Furthermore, the second bracket 12 is extended horizontally and connected to the first bracket 11. The second bracket 12 is used to support the fan body 20. This can ensure that the fan body 20 is installed stably and reliably in the fan installation area 103, while reducing the difficulty of installing the fan body 20 and making the installation of the fan body 20 simpler and more direct.

[0028] Combination Figures 2-7 As shown, the cross-section of the second bracket 12 is L-shaped, including a third limiting plate 121 and a fourth limiting plate 122 that are perpendicular to each other. The third limiting plates 121 of the two second brackets 12 are arranged opposite to each other to limit the fan body 20 to the left and right sides of the wall. The fourth limiting plates 122 of the two second brackets 12 are used to support the fan body 20. The clearance notch 124 is provided on the third limiting plates 121 of the second brackets 12 on both sides.

[0029] Specifically, by connecting the third limiting plate 121 and the fourth limiting plate 122 to each other and setting them perpendicular to each other, the cross-section of the second bracket 12 can be L-shaped. By setting the first mounting bracket assembly 101 and the second mounting bracket assembly 102 at intervals in the left and right directions, the third limiting plates 121 of the two second brackets 12 can be set opposite to each other. This allows the third limiting plates 121 of the two second brackets 12 to limit the left and right walls of the fan body 20. Since the smoke outlet connector 29 of the fan body 20 is located on the left and right walls of the fan body 20, by setting the clearance notch 124 on the third limiting plates 121 of the second brackets 12 on both sides, the clearance notch 124 can avoid the smoke outlet connector 29 under the premise that the third limiting plate 121 is stable, thereby improving the stability and reliability of the installation of the fan body 20.

[0030] Combination Figures 2-7 As shown, the cross-section of the first bracket 11 is L-shaped, including a first limiting plate 111 and a second limiting plate 112 that are perpendicular to each other. The second limiting plates 112 of the two first brackets 11 are arranged opposite to each other and are used to limit the fan body 20 to the left and right sides of the wall. The first limiting plates 111 of the two first brackets 11 are arranged to the front and are used to limit the fan body 20 to the rear side of the wall.

[0031] Specifically, by connecting the first limiting plate 111 and the second limiting plate 112 to each other and setting them perpendicular to each other, the cross-section of the first bracket 11 can be L-shaped. By setting the first mounting bracket assembly 101 and the second mounting bracket assembly 102 at intervals in the left and right directions, the second limiting plates 112 of the two first brackets 11 can be set opposite to each other and limit the fan body 20 to the left and right sides of the wall, thereby improving the stability and reliability of the limiting support of the mounting bracket assembly 10 for the fan body 20.

[0032] Furthermore, the first limiting plates 111 of the two first brackets 11 are arranged facing forward to limit the rearward wall of the fan body 20. This can further improve the stability of the limiting support of the fan body 20 by the mounting bracket assembly 10 while ensuring the stable connection between the first limiting plate 111 and the mounting wall.

[0033] Combination Figures 2-7 As shown, both the first mounting bracket assembly 101 and the second mounting bracket assembly 102 include a third bracket 13, one end of which is connected to the first bracket 11 and the other end is connected to the second bracket 12.

[0034] Specifically, by setting a third bracket 13 and connecting the third bracket 13 between the first bracket 11 and the second bracket 12, a stable triangular structure can be formed between the first bracket 11, the second bracket 12 and the third bracket 13, thereby improving the connection strength between the first bracket 11 and the second bracket 12 and improving the overall structural strength of the mounting bracket assembly 10.

[0035] In this way, the support reliability of the mounting bracket assembly 10 on the fan body 20 can be improved, and the structural deformation of the mounting bracket assembly 10 under the gravity of the fan body 20 can be avoided, thereby ensuring the installation reliability of the fan body 20 and improving the structural reliability of the fan device 100 of the smoke hood 1000.

[0036] In some embodiments of the present invention, the third bracket 13 is spaced apart from the clearance notch 124 so that the third bracket 13 avoids the placement of the smoke outlet connector 29 in the clearance notch 124.

[0037] Combination Figures 2-7 As shown, the fan device 100 of the range hood 1000 also includes a fourth bracket 30. The fourth bracket 30 is connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102. The fourth bracket 30 has a first connection position 33 located at both ends and two second connection positions 34 located between the two first connection positions 33. The first connection position 33 or the second connection position 34 of the fourth bracket 30 is connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102 to adjust its connection position with the first mounting bracket assembly 101 and the second mounting bracket assembly 102.

[0038] Specifically, by setting two first connection positions 33 and two second connection positions 34 on the fourth bracket 30, with the two first connection positions 33 located at both ends of the fourth bracket 30 and the two second connection positions 34 located between the two first connection positions 33, when the dimensions of the fan body 20 in different directions are adapted to the first mounting bracket assembly 101 and the second mounting bracket assembly 102, the spacing distances in the left and right directions of the first mounting bracket assembly 101 and the second mounting bracket assembly 102 are also different due to the different dimensions of the fan body 20 in different directions. Therefore, it is necessary to set the first connection positions 33 and the second connection positions 34 on the fourth bracket 30 to adapt to the different spacing distances in the left and right directions of the first mounting bracket assembly 101 and the second mounting bracket assembly 102.

[0039] That is, when the distance between the first mounting bracket assembly 101 and the second mounting bracket assembly 102 is large, the fourth bracket 30 can be connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102 respectively through the first connection positions 33 at both ends. When the distance between the first mounting bracket assembly 101 and the second mounting bracket assembly 102 is small, the fourth bracket 30 can be connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102 respectively through the two second connection positions 34 between the two ends. In this way, when the orientation of the smoke outlet connector 29 of the fan body 20 is adjusted, the connection position of the fourth bracket 30 with the first mounting bracket assembly 101 and the second mounting bracket assembly 102 can be flexibly changed, so that the installation of the fan body 20 in the fan installation area 103 is more direct and convenient.

[0040] Combination Figures 2-8 As shown, the distance between the surface of the fan body 20 with the smoke outlet connector 29 and the surface parallel to the surface is defined as the width, and the distance between the other two surfaces is defined as the depth. When the first connecting position 33 of the fourth bracket 30 is connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102, the distance between the first mounting bracket assembly 101 and the second mounting bracket assembly 102 is adapted to the width of the fan body 20, and the smoke outlet connector 29 faces the left or right. When the second connection position 34 of the fourth bracket 30 connects the first mounting bracket assembly 101 and the second mounting bracket assembly 102, the distance between the first mounting bracket assembly 101 and the second mounting bracket assembly 102 is adapted to the depth of the fan body 20, and the smoke outlet connector 29 faces the front or rear side.

[0041] Specifically, when the first connection positions 33 at both ends of the fourth bracket 30 are respectively connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102, the distance between the first mounting bracket assembly 101 and the second mounting bracket assembly 102 is adapted to the width of the fan body 20, and the smoke outlet connector 29 faces the left or right side.

[0042] Since the width dimension of the fan body 20 in this embodiment is greater than the depth dimension, when the distance between the first mounting bracket assembly 101 and the second mounting bracket assembly 102 is adapted to the depth of the fan body 20, the two first connection positions 33 on the fourth bracket 30 are respectively connected to the first mounting bracket assembly 101 and the second mounting bracket assembly 102. This facilitates the adjustment of the position of the fan body 20 relative to the mounting bracket assembly 10 and reduces the difficulty of adjusting the orientation of the smoke outlet connector 29 of the fan body 20.

[0043] Combination Figures 2-8As shown, the fourth bracket 30 has an L-shaped cross-section and includes a fifth limiting plate 31 and a sixth limiting plate 32 that are perpendicular to each other. When the smoke outlet connector 29 faces the left or right, the fifth limiting plate 31 is used to support the fan body 20 from the lower side, and the sixth limiting plate 32 limits the front side of the fan body 20. With this configuration, while ensuring the stable connection between the fourth bracket 30 and the first mounting bracket assembly 101 and the second mounting bracket assembly 102, the lower and front sides of the fan body 20 can be limited and supported respectively, which can further improve the stability and reliability of the fan body 20 in the fan installation area 103.

[0044] In addition, with this configuration, the fan body 20 is placed from top to bottom in the fan installation area 103, and then connected to the fan body 20 through the fan connection part 123 on the third limiting plate 121. This allows for a stable installation of the fan body 20 in the fan installation area 103, further reducing the difficulty of installing the fan body 20 in the fan installation area 103 and providing a certain degree of installation error prevention.

[0045] Furthermore, when the smoke outlet connector 29 faces the front or rear, the fifth limiting plate 31 is used to support the fan body 20 from the lower side, and the sixth limiting plate 32 extends downward relative to the fan body 20. When the smoke outlet connector 29 faces the front or rear, the width dimension of the fan body 20 will exceed the length of the second bracket 12 in the front-rear direction. That is, the fan body 20 will protrude from the end of the second bracket 12 away from the first bracket 11. Therefore, the fifth limiting plate 31 is still used to support the fan body 20 from the lower side. However, in order to prevent the sixth limiting plate 32 from blocking the end of the fan body 20 from protruding from the second bracket 12 away from the first bracket 11, the sixth limiting plate 32 needs to extend downward relative to the fan body 20.

[0046] Combination Figure 1 As shown, the range hood 1000 according to this utility model mainly includes: a smoke collection device 200 and a fan device 100 of the range hood 1000. The fan device 1001 is disposed above the smoke collection device 200 and connected to the smoke collection device 200. Thus, when the range hood 1000 is working, the smoke collection device 200 restricts the diffusion range of oil fumes, concentrating and guiding the oil fumes to the position connected to the fan device 100, where they are efficiently sucked away by the fan device 100. This enables the range hood 1000 to perform the function of extracting oil fumes, meeting the user's needs.

[0047] Furthermore, since the smoke collection device 200 and the fan device 100 are independent components, the smoke hood 1000 of this application has a split structure. Therefore, only the orientation of the smoke outlet of the fan device 100 needs to be adjusted, without adjusting the smoke hood 1000 as a whole. This allows for adaptive adjustment of the smoke outlet direction of the smoke hood 1000, thereby expanding the application scenarios of the smoke hood 1000, enhancing its product competitiveness, and improving the user experience.
