[0028] The range hood provided by the present invention is described in detail below with reference to embodiments.

[0029] See also Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is an exploded view of the first structure of the range hood of the present application; Figure 2 This is an exploded view of the second structure of the range hood of the present application; Figure 3 This is the assembly drawing of the range hood rack of this application and different types of rack flanges.

[0030] In this embodiment, the range hood includes a range hood frame 1 and an oil fume guide assembly 3. The oil fume guide assembly 3 includes two types of oil fume guide assemblies, three types of oil fume guide assemblies, or more types of oil fume guide assemblies. The different types of oil fume guide assemblies can be divided according to different shapes, structures, etc., so that the different types of oil fume guide assemblies are different. In this embodiment, the different types of oil fume guide assemblies are divided according to different shapes.

[0031] A smoke outlet 31 is formed in the above-mentioned fume guide component 3, and the bottom of the range hood frame 1 is connected to the smoke outlet 31, so that the smoke in the fume guide component 3 enters the bottom of the range hood frame 1 through the smoke outlet 31, and is sucked away and discharged by the fan component 2 in the range hood frame 1.

[0032] In order to achieve the universalization of range hoods, the range hood frame can be matched and connected with different types of oil fume diversion components, so that different types of oil fume diversion components can share the range hood frame 1, thereby meeting the usage needs of different consumers and improving the universalization and standardization of the product.

[0033] For example, when the oil fume guide component 3 includes a first type of oil fume guide component 3a, a second type of oil fume guide component 3b and a third type of oil fume guide component 3c, the range hood frame 1 can be matched and connected with the first type of oil fume guide component 3a, the second type of oil fume guide component 3b and the third type of oil fume guide component 3c respectively.

[0034] See also Figure 3 In one embodiment, in order to enable different types of oil fume diversion components to share the same range hood frame 1, the range hood includes a frame flange 8, wherein the frame flange 8 is connected between the range hood frame 1 and the oil fume diversion component 3, so as to play a connecting role through the frame flange 8, so that different types of oil fume diversion components can share the same range hood frame 1 through the frame flange 8, thereby achieving universalization and standardization of the range hood.

[0035] The frame flange 8 and the range hood frame 1 can be connected using a stamped point connection method. This method can improve the connection strength between the range hood frame 1 and the frame flange 8, and the assembly operation is simple, convenient, and highly reliable. Of course, the frame flange 8 and the range hood frame 1 can also be connected using screws and nuts, etc., which is not limited here.

[0036] Specifically, see Figure 3 Since different types of oil fume guide components have different structures, in order to match the above-mentioned different types of oil fume guide components to meet the needs of different users and meet the needs of rapid model change, the frame flange 8 in this embodiment also includes at least two types of frame flanges, that is, the bottom of the range hood frame 1 can be respectively connected to different types of frame flanges to achieve assembly of different types of frame flanges, thereby improving the universality and standardization of range hoods.

[0037] The frame flange 8 may include two types of frame flanges, three types of frame flanges, or more types of frame flanges. The different types of frame flanges may be classified based on different structures, assembly methods, and the like. In this embodiment, the frame flange 8 includes three types: a first type of frame flange 8a, a second type of frame flange 8b, and a third type of frame flange 8c.

[0038] Furthermore, the frame flange 8 includes a frame connection portion and a flow guide connection portion, which are fixedly connected. The frame connection portion is connected to the range hood frame 1, and the flow guide connection portion is connected to different types of oil fume diversion components. To achieve universalization of the range hood frame 1, in this embodiment, at least two types of frame flanges have the same frame connection portion structure, allowing different types of frame flanges to be compatible with the range hood frame 1, thereby achieving universalization of the range hood frame 1. Furthermore, at least two types of frame flanges have different flow guide connection portions to connect to different types of oil fume diversion components.

[0039] In addition, a connecting hole 81 is provided between the flanges of different types of racks, and the connecting hole 81 is connected to the smoke outlet 31 of the oil smoke guide assembly 3 , wherein the connecting hole 81 is used for oil smoke to pass through, so that the oil smoke enters the range hood rack 1 through the connecting hole 81 .

[0040] Furthermore, the frame connection portion is provided with at least three folded edges 82 on its outer periphery, with the at least three folded edges 82 facing the range hood frame 1. The frame connection portion is connected to the bottom of the range hood frame 1 via the at least three folded edges 82, so that the bottom of the range hood frame 1 is riveted within the at least three folded edges 82 of the frame flange 8, allowing the range hood frame 1 to be assembled with different types of frame flanges. The folded edges 82 can be connected to the bottom of the range hood frame 1 via stamped points or other methods.

[0041] The bottom of the range hood frame 1 is riveted to at least three flanges 82 of the frame connection using a TOX riveting tool. The number and location of rivet points required using the TOX riveting tool can be determined based on practical needs, as long as they provide a stable assembly between the range hood frame 1 and the frame flange 8. TOX riveting involves the formation of interlocking circular connection points between the two panels at the extrusion point during a gas-liquid energizing stamping process, based on the plastic deformation of the panel material. This creates a point-to-point connection between the two panels.

[0042] like Figure 3 As shown, the first type frame flange 8a is square in shape. Folding edges 82 are provided on the first type frame flange 8a near the bottom of the two side plates 12 and the rear cover plate 132 , while no folding edge 82 is provided near the bottom of the front cover plate 131 .

[0043] A notch is formed on one side of the second type frame flange 8 b close to the bottom of the front cover 131 , and a folded edge 82 is formed close to the bottom of the two side plates 12 and the rear cover 132 .

[0044] The third type of frame flange 8c is square in shape. Folding edges 82 are provided on the third type of frame flange 8c near the two side panels 12, the rear cover 132 and the bottom of the rear cover 132. The height of the folding edge 82 near the front cover 131 is lower than that of the other three folding edges 82.

[0045] The three types of frame flanges have different heights of the folded edges 82 and different shapes of the connecting holes 81. The three types of frame flanges can meet the requirements of the installation of the three types of oil fume guide components and the range hood frame 1 in this embodiment, thereby achieving universalization and standardization of the range hood frame 1.

[0046] Review Figure 1 and Figure 2In practice, the differing positions of the smoke outlets 31 of different types of fume deflectors can lead to certain differences in the positions of the air inlet and smoke outlet 31 of the fan assembly 2. To prevent these differences from affecting the proper exhaust of fume, it is necessary to ensure that different types of fume deflectors are compatible with different types of range hood racks. In this embodiment, when the air inlet of the fan assembly 2 in the range hood rack 1 faces a first direction, the range hood rack 1 can be connected to the first type of fume deflector assembly 3a. When the air inlet of the fan assembly 2 in the range hood rack 1 faces a second direction, the range hood rack 1 can be connected to the second type of fume deflector assembly 3b. This means that the installation method of the range hood rack 1 allows the air inlet of the fan assembly 2 to face either the first or second direction, thereby meeting the needs of different users and improving the universality and standardization of range hoods.

[0047] The first direction and the second direction are oppositely arranged. Figure 1 As shown by arrows X and Y, arrow X is the first direction and arrow Y is the second direction. Arrow X can also be defined as the second direction and arrow Y as the first direction, which is not limited here.

[0048] Therefore, in order to match different types of range hood frames with different types of oil fume deflectors, the air inlet position of the fan assembly 2 needs to be rotated so that the air inlet of the fan assembly 2 matches the corresponding oil fume deflector assembly. To achieve the convenience and stability of replacing the air inlet of the fan assembly 2, in this embodiment, only the range hood frame 1 needs to be rotated, and the fan assembly 2 located in the range hood frame 1 also rotates accordingly.

[0049] For example, the first direction is the positive direction and the second direction is the negative direction, such as Figure 1 As shown, the range hood frame 1 is connected to the first type of oil smoke guide assembly 3a, and the air inlet of the fan assembly 2 takes in air from the positive direction. Figure 2 As shown, the range hood frame 1 is connected to the second type of oil fume guide assembly 3b, and the air inlet of the fan assembly 2 takes in air from the reverse direction. The above different types of range hood frames can meet the matching of different types of oil fume guide assemblies to achieve positive or negative air intake for the fan assembly 2.

[0050] See also Figure 4 、 Figure 5 and Figure 6 , Figure 4 yes Figure 1 A partial schematic diagram of the range hood shown; Figure 5 yes Figure 2 A partial schematic diagram of the range hood shown; Figure 6 This is the third structural diagram of the range hood of this application.

[0051] In this embodiment, the range hood rack 1 may include two types of range hood racks, three types of range hood racks, and more types of range hood racks, wherein different types of range hood racks can be divided according to different structures, assembly forms, etc., so that different types of range hood racks are different.

[0052] Combine Figure 1 and Figure 2 Since the range hood rack 1 in this embodiment includes a first-type range hood rack 1a and a second-type range hood rack 1b, the first-type range hood rack 1a and the second-type range hood rack 1b will be described in detail below. The first-type range hood rack 1a includes two side panels 12, a front cover 131, a rear cover 132, and a top panel 14. The side panels 12 are structurally identical, and the front cover 131 and the rear cover 132 are structurally identical. The side panels 12 are spaced relative to each other along a first direction. The front cover 131 and the rear cover 132 are both connected to the side panels 12 and spaced relative to each other along a second direction.

[0053] The top panel 14 is connected to the tops of the two side panels 12, the front cover 131, and the rear cover 132. The top panel 14, the two side panels 12, the front cover 131, and the rear cover 132 enclose an installation space 11 for mounting the fan assembly 2. An air outlet mounting port 141 is mounted on the top panel 14. This air outlet mounting port 141 is connected to the air outlet of the fan assembly 2, allowing oil smoke from the air outlet of the fan assembly 2 to be discharged through this air outlet mounting port 141.

[0054] The bottoms of the two side panels 12, front cover 131, and rear cover 132 form the bottom of the range hood frame 1, which is connected to the smoke outlet 31 of the oil fume deflector assembly 3, allowing oil fumes from the oil fume deflector assembly 3 to exit through the smoke outlet 31 and enter the bottom of the range hood frame 1. The air inlet of the fan assembly 2, the installation space 11, and the smoke outlet 31 of the oil fume deflector assembly 3 are interconnected, allowing waste from stove combustion and oil fumes harmful to the human body generated during cooking to flow through the smoke outlet 31 of the oil fume deflector assembly 3, the installation space 11, and the air inlet in sequence and be discharged outdoors.

[0055] Specifically, the side panels 12 and the top panel 14 are integrally formed and arranged in an inverted U-shape. The bottom of the side panels 12 is arranged to have a rotationally symmetrical structure. When the top panel 14 and the two side panels 12 are rotated 180 degrees around the rotationally symmetrical structure, they can overlap with their original structure. The positions of the side panels 12 are swapped, and the position of the air inlet of the fan assembly 2 is also changed.

[0056] For example, the two side panels 12 include a first side panel 12a and a second side panel 12b. Figure 1As shown, when the range hood frame 1 is matched with the first type of oil smoke guide assembly 3a, the first side panel 12a and the second side panel 12b are in the initial state, and the air inlet of the fan assembly 2 faces the front cover 131. When the range hood frame 1 is matched with the second type of oil smoke guide assembly 3b, as shown in FIG. Figure 2 As shown, the positions of the first side panel 12 a and the second side panel 12 b are swapped, wherein the air inlet of the fan assembly 2 faces the rear cover plate 132 .

[0057] Since only the two side panels 12 and the top panel 14 rotate, in order for the front cover 131 and the rear cover 132 to be respectively connected to the rear ends and front ends of the two side panels 12 after rotation, the front cover 131 and the front ends of the two side panels 12, and the rear cover 132 and the rear ends of the two side panels 12 have the same connection structure, that is, regardless of whether the two side panels 12 and the top panel 14 rotate, the front cover 131 and the rear cover 132 can be installed on the front ends and rear ends of the two side panels 12, thereby improving the versatility of the product.

[0058] Review Figure 1 and Figure 2 To protect the first-type range hood frame 1a and enhance its aesthetics, the range hood also includes a decorative cover 7, which is mounted on the range hood frame 1. Since only the top panel 14 and two side panels 12 of the first-type range hood frame 1a rotate 180° around their center, when the fan inlet of the first-type range hood frame 1a faces the first or second direction, the front cover 131 and rear cover 132 do not need to rotate. Therefore, the decorative cover 7 only covers the surfaces of the two side panels 12 and the front cover 131 of the range hood frame 1. The aforementioned fixing structure only needs to be installed on the rear cover 132.

[0059] See also Figure 6 , Figure 6 The front surface of the middle range hood frame is concealed. The second type range hood frame 1b includes a range hood frame body, which is formed with a mounting space 11 for mounting the fan assembly 2. An air outlet mounting port 141 is formed at the top of the range hood frame body, and a smoke outlet 31 connected to the oil fume deflector assembly 3 is formed at the bottom of the range hood frame body. The air inlet of the fan assembly 2, the mounting space 11, and the smoke outlet 31 of the oil fume deflector assembly 3 are interconnected, allowing waste from stove combustion and harmful oil fume generated during cooking to flow through the smoke outlet 31 of the oil fume deflector assembly 3, the mounting space 11, and the air inlet in sequence, and then be discharged outdoors.

[0060] Specifically, compared to the first type range hood frame 1a, the second type range hood frame 1b has an integrally formed frame body. The frame body includes a front surface, a rear surface, and two side surfaces. The bottom of the frame body is a rotationally symmetrical structure. After the frame body rotates 180° around its rotational center, it repositions with the side panels 12, the front cover 131, and the rear cover 132, as well as the air inlet of the fan assembly 2, are swapped.

[0061] To protect the second range hood frame 1b and enhance its aesthetics, the range hood also includes a decorative cover 7, which is mounted on the range hood frame 1. When the range hood frame body of the second range hood frame 1b rotates 180° around its center, that is, when the air inlet of the fan assembly 2 in the range hood frame body faces the first direction, the decorative cover 7 covers the front surface and both side surfaces. When the range hood frame body rotates 180° around its center, the air inlet of the fan assembly 2 faces the second direction, the rear surface of the range hood frame body is located at the same position as its front surface, and the front surface is located at the same position as its rear surface, that is, the decorative cover 7 covers the rear surface and both side surfaces.

[0062] Considering that the decorative cover 7 needs to be installed on the front surface or the rear surface of the range hood frame body, corresponding fixing structures need to be provided on both the front cover plate 131 and the rear cover plate 132 to mount the decorative cover 7 on the range hood frame body through the fixing structures.

[0063] The fixing structure in the first type range hood frame 1a and the second type range hood frame 1b described above may be any structure, as long as it can achieve a stable connection between the decorative cover 7 and the range hood frame 1. In practice, to simplify the fixing structure and save costs, the fixing structure may be screws and nuts. Several screw holes are provided in the decorative cover 7, and connecting holes corresponding to the aforementioned screw holes are provided on the front cover 131 or the front and rear surfaces of the range hood frame body. Screws are sequentially inserted through the screw holes in the decorative cover 7 and the connecting holes in the front cover 131 or the front and rear surfaces of the range hood frame body, and then locked with nuts. This achieves a stable connection between the decorative cover 7 and the range hood frame 1 or the range hood frame body, while also facilitating disassembly.

[0064] In this embodiment, the range hood includes a range hood frame and a fume diversion assembly. The range hood frame includes at least two types of range hood frames; the fume diversion assembly includes at least two types of fume diversion assemblies, each of which has a fume outlet. The bottom of the range hood frame is connected to the fume outlet, and each type of range hood frame can be connected to each type of fume diversion assembly. This allows different types of fume diversion assemblies to share the range hood frame, thereby meeting the needs of different consumers and improving product commonality and standardization.

[0065] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
