[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] The range hood frame and the range hood provided by the present invention are described in detail below with reference to the embodiments.

[0033] See also Figure 1 and Figure 2 , Figure 1 This is an exploded schematic diagram of the first embodiment of the range hood of the present application; Figure 2 This is an exploded schematic diagram of the second embodiment of the range hood of the present application.

[0034] In this embodiment, the range hood frame 1 includes two side panels 12, a front cover 131 and a rear cover 132. The two side panels 12 are spaced relative to each other along a first direction. The two side panels 12 include opposite first and second connecting ends. The front cover 131 and the rear cover 132 are spaced relative to each other along a second direction. Figure 1 In the double-headed arrow shown, X points to a first direction and Y points to a second direction.

[0035] The front cover 131 is connected to the first connection ends of the two side panels 12, and the rear cover 132 is connected to the second connection ends of the two side panels 12, so that the front cover 131 and the rear cover 132 are respectively connected to the first connection ends and the second connection ends of the two side panels 12. The two side panels 12, the front cover 131, and the rear cover 132 enclose an installation space 11, which is used to install the fan assembly 2.

[0036] When the air outlet of the fan assembly 2 in the range hood rack 1 faces the front cover 131, that is, the air inlet of the fan assembly 2 is located at the rear, and at this time the front cover 131 is connected to the first connecting ends of the two side panels 12; when the air outlet of the fan assembly 2 in the range hood rack 1 faces the rear cover 132, that is, the air inlet of the fan assembly 2 is located at the front, and at this time the front cover 131 is connected to the second connecting ends of the two side panels 12.

[0037] Since the positions of the two side panels 12 are also exchanged during the process of switching between the rear-positioned and front-positioned air inlet of the fan assembly 2, that is, the air inlet of the fan assembly is rear-positioned or front-positioned, the front cover 131 can match the first connecting end or the second connecting end of the two side panels 13 to meet the requirements of the installation of the front cover 131 and the rear cover 132 when the air inlet of the fan assembly 2 in the range hood rack 1 is rear-positioned or front-positioned, thereby realizing the universalization and standardization of the range hood rack 1.

[0038] See also Figure 3 , Figure 3 This is an exploded schematic diagram of an embodiment of a range hood frame of the present application (including two front covers).

[0039] Combine Figure 1 and Figure 2 To further achieve universalization and standardization of the range hood rack 1, the front cover 131 in the range hood rack 1 in this embodiment includes a first-type front cover 131a and a second-type front cover 131b. Both the first-type front cover 131a and the second-type front cover 131b can be connected to the first and second connecting ends of the two side panels 12. This allows the range hood rack 1 to accommodate both the first-type front cover 131a and the second-type front cover 131b, meeting the needs of different consumers and the factory's rapid model changeover requirements, thereby achieving universalization and standardization of the range hood rack 1. Specifically, different first-type front covers 131a and second-type front covers 131b can be replaced according to different needs.

[0040] The first and second front cover plates 131a, 131b can be categorized based on different performance characteristics. For example, the first front cover plate 131a is a conventional performance front cover plate 131, while the second front cover plate 131b is a high-performance front cover plate 131. The high-performance front cover plate 131 can improve the range hood frame 1's range hood extraction performance, and other performance characteristics. Of course, other assembly performance characteristics can also be achieved. The first and second front cover plates 131a, 131b can also be categorized based on different structural types, as long as the first and second front cover plates 131a, 131b are different.

[0041] See also Figure 4 and Figure 5 , Figure 4 is a cross-sectional schematic diagram of the third embodiment of the range hood of the present application; Figure 5A schematic cross-sectional view of the fourth embodiment of the range hood of the present application.

[0042] Specifically, combined Figure 3 In this embodiment, the first-type front cover plate 131a is a conventional performance front cover plate 131, while the second-type front cover plate 131b is a high-performance front cover plate. Because the second-type front cover plate 131b includes an upper cover portion and a lower cover plate, in the second direction, the distance from the upper cover portion of the second-type front cover plate 131b to the rear cover plate 132 is greater than the distance from the first-type front cover plate 131a to the rear cover plate 132. This increases the distance between the fan assembly 2 and the second-type front cover plate 131b, thereby adjusting the size of the fan assembly 2's air inlet and improving the range hood extraction efficiency of the range hood frame 1.

[0043] Furthermore, the upper and lower cover portions have different thicknesses, with the upper cover portion being thicker than the lower cover plate. Simultaneously, the upper cover portion protrudes from the lower cover portion in the first direction, with the lower cover portion having a thickness equivalent to that of the first-type rear cover plate 132. To increase the distance between the second-type front cover plate 131b and the rear cover plate 132, this embodiment provides an upper cover groove (not shown) on the side of the upper cover portion facing the fan assembly 2. Because the upper cover groove extends in the first direction, it increases the distance between the second-type front cover plate 131b and the fan assembly 2. The shape and depth of the upper cover groove can be determined based on actual conditions and are not limited herein.

[0044] For example, when the range hood rack 1 is used in the process of matching with the cabinet, such as Figure 5 As shown, the first type of front cover 131a can be hidden in the cabinet door 100. Figure 4 As shown, the upper cover portion of the second type front cover plate 131b is flush with the vertical surface of the cabinet door 100. Compared with the first type front cover plate 131a, the second type front cover plate 131b increases the distance between the air inlet of the fan assembly 2 in the range hood frame 1 and the front cover plate 131, thereby effectively improving the range hood extraction effect.

[0045] See also Figure 6 、 Figure 7 and Figure 8 , Figure 6 yes Figure 3 The front view of the range hood frame is shown; Figure 7 yes Figure 6 A schematic cross-sectional view of AA is shown; Figure 8 yes Figure 7 Schematic diagram of the structure of B shown.

[0046] Combine Figure 3To further enhance the universality of the range hood chassis 1, in this embodiment, both the first and second types of front cover plates 131a, 131b are equipped with the same side panel connection structure 5. Furthermore, the first and second connecting ends of the two side panels 12, which are located opposite each other, are formed with the same cover plate connection structure 4. When the two side panels 12 are rotated 180° around their respective centers, the identical cover plate connection structures 4 allow both the first and second types of front cover plates 131a, 131b to mate with the first or second connecting ends of the two side panels 12. This further enhances the universality of the range hood chassis 1, allowing it to accommodate different types of front cover plates 131.

[0047] In the actual process, when the two side panels 12 rotate 180° around their own center, the installation position of the rear cover 132 will also change. In order to match the installation of the rear cover 132, the rear cover 132 is also provided with a side panel connection structure 5 that is the same as the first type of front cover 131a and the second type of front cover 131b, so that the rear cover 132 is connected to the cover connection structure 4 through the side panel connection structure 5 to realize the connection of the rear cover 132, thereby realizing the universalization of the range hood frame 1.

[0048] For example, the first connecting ends of the two side panels 12 are connected to the front cover 131, and the second connecting ends of the two side panels 12 are connected to the rear cover 132. When the two side panels 12 are rotated 180 degrees, the positions of the first and second connecting ends of the two side panels 12 change. At this time, the first connecting ends of the two side panels 12 are connected to the rear cover 132, and the second connecting ends of the two side panels 12 are connected to the front cover 131. The installation positions of the front cover 131 and the rear cover 132 do not need to be changed. Only the position of the two side panels 12 needs to be rotated to still meet the installation requirements of the range hood frame 1, thereby achieving universalization of the range hood frame 1.

[0049] In the actual process, in order to match the front cover plate 131 and the rear cover plate 132 with the first connection end and the second connection end of the two side panels 12 respectively, the two cover plate connection structures of the two side panels 12 are respectively corresponding to the setting positions of the side panel connection structure 5, so as to ensure that after the two side panels 12 are rotated 180° around their center, any front cover plate 131 and rear cover plate 132 can adapt to the first connection end and the second connection end of the side panel 12.

[0050] The cover plate connection structure 4 at the first connection end and the second connection end of the two side panels 12 can be a threaded hole, and the side panel connection structure 5 can be a bolt, which is threadedly connected to the threaded hole, so that the front cover plate 131 and the rear cover plate 132 are respectively connected to the first connection end and the second connection end of the two side panels 12.

[0051] The side panel connection structure 5 may also be a buckle 41, and the cover plate connection structure 4 may be a locking hole 51, etc., with the buckle 41 being locked into the locking hole 51. Of course, the cover plate connection structure 4 and the side panel connection structure 5 may also be other structures that can connect the front cover plate 131 and the rear cover plate 132 to the first connection end and the second connection end of the two side panels 12, respectively, and will not be described in detail here.

[0052] In this embodiment, in order to improve the assembly efficiency and standardization between the front cover plate 131 and the rear cover plate 132 and the two side plates 12, one of the cover plate connection structure 4 and the side plate connection structure 5 is a buckle 41, and the other of the cover plate connection structure 4 and the side plate connection structure 5 is a latch hole 51, specifically in the following two cases:

[0053] The first case: the cover plate connection structures 4 at the first connection ends and the second connection ends of the two side panels 12 are both set as snaps (not shown in the figure), and the side panel connection structures 5 on the front cover plate 131 and the rear cover plate 132 are both set as snap holes (not shown in the figure). The front cover plate 131 and the rear cover plate 132 are respectively connected to the snaps at the first connection ends and the second connection ends of the two side panels 12 through the snap holes, so as to realize the rapid installation of the front cover plate 131 and the rear cover plate 132 with the side panels 12, thereby realizing the standardization of the assembly of the range hood frame 1.

[0054] The second situation: Figure 8 As shown, the cover plate connection structures 4 on the first connection end and the second connection end of the two side panels 12 can be set as card holes 51, and the side panel connection structures 5 on the front cover plate 131 and the rear cover plate 132 are set as buckles 41. The front cover plate 131 and the rear cover plate 132 are directly connected to the card holes 51 of the first connection end and the second connection end of the two side panels 12 through the buckles 41, so as to realize the rapid installation of the front cover plate 131 and the rear cover plate 132 to the two side panels 12, thereby realizing the standardization of the assembly of the range hood frame 1.

[0055] The buckle 41 can be integrally formed or independently mounted on the first and second connecting ends of the front cover 131 / rear cover 132 or the side panels 12, and the latch hole 51 can partially or completely penetrate the first and second connecting ends of the front cover 131 / rear cover 132 or the side panels 12. The buckle 41 and the latch hole 51 can be of any structure as long as they can be assembled and connected.

[0056] During the assembly process of the buckle 41 and the buckle hole 51, when the front cover 131 and the rear cover 132 are assembled at the first connection end and the second connection end of the two side panels 12, due to the structure of the buckle 41 itself, the assembly between the front cover 131 and the rear cover 132 and the side panel 12 is unstable and easy to fall off, which affects consumer use.

[0057] Therefore, in this embodiment, the buckle 41 is tilted toward the upper portion or bottom portion of the side panel 12 to achieve a stable connection between the buckle 41 and the latch hole 51. If the latch hole 51 is provided at the first and second connection ends of the side panels 12, the buckle 41 is tilted toward the front cover 131 and the rear cover 132, with the free end of the buckle 41 tilted toward the bottom portion of the side panel 12, and the buckle 41 is directly engaged with the latch hole 51.

[0058] like Figure 8 As shown, when the free end of the buckle 41 is just inserted into the locking hole 51, the front cover 131 and the rear cover 132 slide directly into the locking hole 51 due to their own weight. This not only allows for quick assembly between the front cover 131 and the rear cover 132 and the first and second connecting ends of the two side panels 12, but also prevents the front cover 131 and the rear cover 132 from falling off the two side panels 12, resulting in a stable connection and labor-saving assembly. At the same time, the buckle 41 can be completely hidden within the first and second connecting ends of the two side panels 12, improving the aesthetics of the range hood frame 1 and preventing scratches on consumers or damage to the external decorative cover caused by the buckle 41 being exposed outside the front cover 131 and the rear cover 132.

[0059] For example, latch holes (not shown) are provided on the front cover 131 and the rear cover 132, and latches (not shown) are provided at an angle at the first and second connecting ends of the two side panels 12, wherein the free ends of the latches are tilted toward the upper portion of the side panels 12, and the latch holes are correspondingly inserted into the latches. Because the free ends of the latches are tilted toward the upper portion of the side panels 12, the front cover 131 and the rear cover 132 are not easily detached from the two side panels 12. To prevent the free ends of the latches from extending from the latch holes to the outside of the front cover 131 and the rear cover 132, thereby affecting the aesthetics of the range hood frame 1 or affecting the use of the range hood by consumers, the latch holes in the front cover 131 and the rear cover 132 can be configured as non-through holes. Of course, the latch holes can also be configured as through holes.

[0060] In order to enhance the connection strength between the buckle 41 and the latch hole 51, the lateral widths of the buckle 41 and the latch hole 51 may be increased, thereby increasing the contact area between the buckle 41 and the latch hole 51. Alternatively, a guide piece may be provided on the side wall of the latch hole 51, wherein the guide piece is provided in the same manner as the buckle 41. The guide piece not only guides the buckle 41 when entering the latch hole 51, but also increases the contact area between the buckle 41 and the guide piece, thereby enhancing the connection strength between the buckle 41 and the latch hole 51.

[0061] The front cover 131 and rear cover 132, or the first and second connecting ends of the side panels 12, are each provided with one, two, or more latches 41. The number and position of the latches 41 correspond to the number and position of the latch holes 51. The number of latches 41 and latch holes 51 is not limited herein. In this embodiment, three latches 41 are provided on each side of the front cover 131 and rear cover 132, and six latch holes 51 are provided on each side of the first and second connecting ends of the side panels 12.

[0062] Furthermore, to facilitate the engagement of the buckles 41 of the front and rear cover plates 131, 132 with the snap holes 51 at the first and second connection ends of the side panels 12, side edges are vertically disposed at the first and second connection ends of the side panels 12. The side edges are disposed parallel to the contact surfaces of the front and rear cover plates 131, 132. The snap holes 51 are disposed on the side edges to facilitate the connection of the front and rear cover plates 131, 132 to the side panels 12.

[0063] Please continue reading Figure 3 、 Figure 6 、 Figure 7 and Figure 8 In one embodiment, when the front cover plate 131 and the rear cover plate 132 are matched with the two side panels 12 through the cover plate connecting structure 4 and the side panel connecting structure 5, the front cover plate 131 and the rear cover plate 132 may cause the side panel connecting structure 5 to be deformed or damaged due to their own gravity, thereby affecting the connection between the side panel connecting structure 5 and the cover plate connecting structure 4.

[0064] Because the range hood frame 1 includes a top plate 14, which is connected to the tops of the side panels 12 and the front and rear cover plates 131 and 132, the top plate 14, the side panels 12, the front and rear cover plates 131, and 132 form the aforementioned installation space 11. To further enhance the stability of the connection between the front and rear cover plates 131, 132 and the side panels 12, the front and rear cover plates 131, 132 are each connected to the top plate 14 via a cover plate fixing structure 6.

[0065] Specifically, the same cover plate fixing structure 6 is provided at the edge of the top plate 14 near the front cover plate 131 and the rear cover plate 132. Through the same cover plate fixing structure 6, any one of the front cover plate 131 and the rear cover plate 132 can be connected, so that the front cover plate 131 and the rear cover plate 132 can be respectively covered on the side plate 12 through the top plate 14, further improving the connection stability of the front cover plate 131, the rear cover plate 132 and the side plate 12; at the same time, it can meet the requirement that after the two side plates 12 are rotated 180° around their center, they can be connected to any front cover plate 131 and the rear cover plate 132, so that the range hood rack 1 can be universalized and standardized, thereby improving the installation efficiency of the range hood rack 1.

[0066] Combine Figure 3 and Figure 7 , continue reading Figure 10 In order to further improve the stability and assembly efficiency of the connection between the front cover plate 131, the rear cover plate 132 and the side plate 12, a flange 133 is formed on the front cover plate 131 and the rear cover plate 132 facing the top plate 14. The flange 133 is covered on the edge of the top plate 14 and then fixedly connected to the top plate 14 through the cover plate fixing structure 6, so that the front cover plate 131 and the rear cover plate 132 are stably connected to the side plate 12, thereby improving the stability of the range hood frame 1.

[0067] At the same time, due to the existence of the flange 133, when the side panel connecting structure 5 on the front cover 131 and the rear cover 132 is assembled on the cover connecting structure on the side panel 12, the flange 133 can play a role of pre-positioning, and the rear side panel connecting structure 5 is respectively connected to the cover connecting structure 4, thereby improving the assembly efficiency of the front cover 131, the rear cover 132 and the side panel 12, thereby improving the assembly efficiency of the range hood frame 1.

[0068] The flanges 133 may be provided only on the edges of the front cover plate 131 and the rear cover plate 132 facing the top plate 14, or may be provided simultaneously on the edges of the front cover plate 131 and the rear cover plate 132 facing the top plate 14 and the first connection end and / or the second connection end facing the side plate 12. The flanges 133 may be provided intermittently on the edges of the front cover plate 131 and the rear cover plate 132 facing the top plate 14 and the first connection end and / or the second connection end facing the side plate 12.

[0069] In actual practice, in order to simplify the cover fixing structure 6 and save costs, the cover fixing structure 6 can be screws and nuts. By opening screw holes on the flange 133, a top plate hole is opened at the position corresponding to the screw hole on the top plate 14. The screws pass through the screw holes on the flange 133 and the top plate holes on the top plate 14, and are fixed by bolts to achieve a stable connection between the front cover 131, the rear cover 132 and the top plate 14, and it is also convenient for disassembly and installation.

[0070] In other embodiments, the cover plate fixing structure 6 can be a pin and a pin hole. By opening a pin hole on the flange 133, a top plate hole is opened at the position corresponding to the pin hole on the top plate 14. The pin passes through the pin hole on the flange 133 and the top plate hole on the top plate 14 to achieve positioning between the front cover plate 131, the rear cover plate 132 and the top plate 14, so that the front cover plate 131 and the rear cover plate 132 and the top plate 14 play a connecting role.

[0071] The cover plate fixing structure 6 may also be other structures as long as it can satisfy the connection between the front cover plate 131 , the rear cover plate 132 and the top plate 14 , and is not limited here.

[0072] See also Figure 9 、 Figure 10 and Figure 11 , Figure 9 yes Figure 1 A partial schematic diagram of a range hood frame is shown; Figure 10 yes Figure 2 A partial schematic diagram of a range hood frame is shown; Figure 11 yes Figure 10 Another partial schematic diagram of the range hood rack is shown.

[0073] Combine Figure 3 Because the top panel 14 is formed with an air outlet 141 for exhausting oil smoke, and the electrical component 7 is located on top of the top panel 14, the range hood requires wiring, one end of which is connected to the electrical component 7 and the other end to an external circuit. To conceal the range hood wiring within the range hood frame 1, the side panels 12 are provided with a first wire trough 15 and a second wire trough 16. These troughs can be used to store the wiring, preventing it from being exposed to the external environment. One end of the first wire trough 15 and the other end of the wire trough 16 are located near the top panel 14, and the other end is located near the bottom of the range hood frame 1.

[0074] Since the two side plates 12 rotate 180 degrees around themselves, Figure 10 and Figure 11 , the two side panels 12 will drive the top panel 14 to rotate, and the position of the air outlet mounting port 141 on the top panel 14 will change relative to the position of the air outlet mounting port 141 in the initial state, causing the position of the electrical component 7 on the top panel 14 to change relative to the position of the electrical component 7 in the initial state. Because the electrical component 7 is arranged between the air outlet mounting port 141 and the side panel 12 away from the air outlet mounting port 141, that is, the front and rear ends of the side panel 12 away from the air outlet mounting port 141 of the two side panels 12 are respectively provided with a first wire protection groove 15 and a second wire protection groove 16 for the passage of lines. When the range hood frame 1 rotates, because the air outlet mounting port 141 and the electrical component 7 have changed, the first wire protection groove 15 and the second wire protection groove 16 are always located on the side panel 12 away from the air outlet mounting port 141.

[0075] For example, the two side panels 12 include a first side panel 12a and a second side panel 12b, and the first wire protection groove 15 and the second wire protection groove 16 are always set at the front end and the rear end of the second side panel 12b.

[0076] In an alternative embodiment, it is also possible to consider setting a third wire protection groove (not shown in the figure) at the front end of the first side panel 12a and a fourth wire protection groove (not shown in the figure) at the rear end of the second side panel 12b to hide and protect part of the lines of the electrical component 7.

[0077] The first cable duct 15 is formed by a groove on one end of the top plate 14 near the side plate 12 and a curved edge on one side of the side plate 12 near the cover plate. Similarly, the second cable duct 16 has the same structure as the first cable duct 15. To ensure that the wiring positions do not change after the two side plates 12 rotate, the first and second cable ducts 15 and 16 are arranged opposite each other in either the first or second direction.

[0078] Also, please continue to read Figure 9 、 Figure 10 and Figure 11 , protrusions 17 are formed on each of the two side panels 12. The protrusions 17 face the installation space 11, and mounting holes are provided in the protrusions 17. To mount the fan assembly 2 on the range hood frame 1, the range hood frame 1 in this embodiment further includes a fan bracket 8. The fan bracket 8 connects to the mounting holes in the protrusions 17, allowing the fan bracket 8 to be mounted within the installation space 11, thereby providing a mounting fulcrum for the fan assembly 2, allowing the fan assembly 2 to be stably mounted within the range hood frame 1 via the fan bracket 8.

[0079] Please read back Figure 1 and Figure 2 In this embodiment, the range hood includes a range hood frame 1. It should be noted that the range hood frame is the range hood frame described in the above embodiment and will not be described in detail here.

[0080] 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.
