[0036] As a crucial component of range hoods, the fume hood collects cooking fumes and steam, exhausting these harmful substances outdoors through a built-in fan system. However, due to limitations in structural design and assembly processes, existing fume hoods often have uneven top surfaces. This unevenness not only affects aesthetics but, more importantly, increases cleaning difficulty, requiring users to spend more time and effort on daily maintenance. Furthermore, an uneven top surface can cause fume accumulation, compromising the range hood's exhaust efficiency.

[0037] In order to solve this technical problem, the present invention proposes a smoke collection hood 100 .

[0038] See also Figures 1 to 5 In one embodiment of the present invention, the smoke hood 100 includes a hood body 10, a front frame 20 and a side frame 30; the front frame 20 is arranged at the front end of the hood body 10; the side frame 30 is arranged at the side end of the hood body 10; the top surfaces of the hood body 10, the front frame 20 and the side frame 30 are arranged flush; the cleaning convenience of the smoke hood 100 is improved by the flatness of the top surface of the smoke hood 100.

[0039] In the technical solution of the present invention, a front frame 20 is provided at the front end of the hood body 10, and at the same time, a side frame 30 is provided at the side end of the hood body 10 to enhance the structural strength of the front end and side end of the hood body 10. After the front frame 20 and the side frame 30 are assembled to the hood body 10, the top surfaces of the hood body 10, the front frame 20 and the side frame 30 are arranged flush, that is, the top surfaces of the three are located on the same plane, which helps to achieve the flatness of the top surface of the smoke hood 100, thereby improving the cleaning convenience and maintenance efficiency of the smoke hood 100, and at the same time, it is also convenient to improve the overall viewing quality of the smoke hood 100.

[0040] It should be noted that the front end in the present invention specifically refers to the side of the smoke hood 100 facing the user, the rear end specifically refers to the side where the smoke hood 100 is connected to the wall, and the side end specifically includes the left end and the right end. Therefore, in the embodiment of the present invention, two side frames 30 are provided, and are respectively provided on the left end and the right end of the smoke hood 100.

[0041] See also Figures 2 to 3 In an embodiment of the present invention, the cover body 10 includes a top plate 11, and a first positioning groove 111 is provided at the front end of the top plate 11. The front frame 20 includes a front stop portion 21 and a first overlapping portion 22 connected to the front stop portion 21. The first overlapping portion 22 is overlapped with the first positioning groove 111. It can be understood that through the setting of the first positioning groove 111, on the one hand, as a positioning structure of the front frame 20 on the top plate 11, it is convenient for the front frame 20 to be quickly overlapped on the first positioning groove 111 through the first overlapping portion 22. On the other hand, because the first overlapping portion 22 is inlaid with the first positioning groove 111, it can reduce the height of the front frame 20 protruding from the top plate 11 and reduce the unevenness of the top surface of the smoke hood 100, and can also increase the effective contact area between the front frame 20 and the top plate 11, thereby enhancing the installation stability and reliability of the front frame 20 on the top plate 11, thereby improving the structural strength of the front end of the smoke hood 100.

[0042] The front frame 20 also includes a front stop 21. The side of the front stop 21 facing the hood body 10 is connected to a first overlap portion 22, making the front frame 20 an L-shaped structure. This facilitates the front frame 20 to be hung on the first positioning groove 111 through the first overlap portion 22, which not only facilitates the fixed connection between the first overlap portion 22 and the top plate 11, but also facilitates the front stop 21 to reliably block the connection structure exposed at the front end of the hood body 10, improving the overall aesthetics and facilitating subsequent maintenance and cleaning. The connection methods of the first overlap portion 22 and the top plate 11 include but are not limited to snap-on connection 31 and screw connection, which can facilitate the assembly and maintenance of the internal structure of the smoke hood 100 to a certain extent.

[0043] Specifically, in an embodiment of the present invention, the depth of the first positioning recess 111 is the same as the thickness of the first overlapping portion 22. This ensures that the top surface of the first overlapping portion 22 is in the same plane as the top surface of the top plate 11, thereby achieving a flat top surface of the smoke hood 100. Furthermore, when debris such as oil smoke accumulates on the top surface of the smoke hood 100, the user can quickly wipe away the debris, ensuring the cleanliness of the top surface of the smoke hood 100. Of course, the overall space occupied by the smoke hood 100 can also be effectively reduced. The thickness direction of the first overlapping portion 22 is the up-down direction of the smoke hood 100.

[0044] In addition, in the front and rear directions of the smoke hood 100, the width of the first overlapping portion 22 can be the same as the width of the first positioning groove 111, so that the gap between the first overlapping portion 22 and the top plate 11 can be as small as possible to facilitate cleaning. At the same time, the front stop portion 21 can abut against the front end of the hood body 10 to improve the structural strength of the hood body 10.

[0045] Specifically, in an embodiment of the present invention, the first overlapping portion 22 is locked and connected to the top plate 11 by fasteners, wherein the bottom wall of the first positioning groove 111 is provided with a plurality of first positioning holes. When the first overlapping portion 22 is overlapped with the first positioning groove 111, the first connecting hole on the first overlapping portion 22 is connected to the first positioning hole, and the fastener can be passed through the first connecting hole and the first positioning hole in sequence from top to bottom to complete the fastening connection between the first overlapping portion 22 and the top plate 11; at this time, the fastener is configured as a screw.

[0046] The top surface of the first overlapping portion 22 is provided with a receiving recess 221 corresponding to the screw nut. The receiving recess 221 is connected to the first connection hole. On the basis of ensuring a reliable connection between the front frame 20 and the top plate 11, the nut is ensured to be completely received in the receiving recess 221, thereby ensuring that there is no protruding structure on the top surface of the first overlapping portion 22. However, the present design is not limited to this. In other embodiments, the first overlapping portion 22 is provided with a buckle on the side facing the bottom wall or side wall of the first positioning recess 111. In this case, the first positioning recess 111 is provided with a buckle hole that cooperates with the buckle.

[0047] See also Figures 2 to 4 In an embodiment of the present invention, the hood body 10 includes a top plate 11, and the side edge of the top plate 11 is provided with a side flange 12 extending downward, and the side flange 12 is provided with a guide card hole 121, and the side frame 30 is provided with a buckle 31 that is engaged with the guide card hole 121. It can be understood that the engagement of the buckle 31 with the guide card hole 121 helps the side frame 30 to be as close to the side flange 12 as possible, thereby narrowing the gap between the side frame 30 and the side flange 12, reducing the risk of debris hiding in the gap, and at the same time, it is also convenient to improve the flatness of the top surface of the smoke hood 100 and enhance the cleaning convenience of the smoke hood 100.

[0048] In particular, a plurality of guide holes 121 are provided at intervals in the front-to-back direction of the smoke hood 100, which helps to enhance the connection strength between the side frame 30 and the side flange 12. In one embodiment, the guide holes 121 have a guiding function to guide the buckles 31 to slide forward and backward along the side flange 12. Thus, after each buckle 31 is inserted into the corresponding guide hole 121, the side frame 30 slides in the front-to-back direction under the guidance of the guide hole 121 and is fixed in the guide hole 121 by the buckle 31, thereby achieving stable installation of the side frame 30 on the side flange 12. In other embodiments, the buckle 31 can be pressed into the guide hole 121.

[0049] See also Figure 3 In the embodiment of the present utility model, the guide card hole 121 includes a first hole section 122, a reducing hole section 123 and a second hole section 124 connected in sequence in the rear direction, the upper and lower widths of the first hole section 122 are greater than the upper and lower widths of the second hole section 124, the buckle 31 penetrates from the first hole section 122 and slides into the second hole section 124 along the reducing hole section 123 to buckle with the edge of the second hole section 124. It can be understood that the first hole section 122 serves as a pre-positioning section of the guide card hole 121, and its upper and lower widths need to be greater than the upper and lower widths of the buckle 31, so that the buckle 31 can quickly extend into the first hole section 122, and the upper and lower widths of the second hole section 124 are adapted to the upper and lower widths of the buckle 31, reducing the risk of the buckle 31 shaking in the second hole section 124 and causing the side frame 30 to separate from the side flange 12, thereby improving the connection reliability of the side frame 30 and the side flange 12.

[0050] In addition, the upper and lower widths of the variable-diameter hole section 123 are gradually reduced in the rearward direction to adapt to the changes in the upper and lower widths of the first hole section 122 and the second hole section 124, thereby ensuring the structural stability of the side flange 12 and facilitating the gradual transition of the guide buckle 31 from the first hole section 122 to the second hole section 124, reducing the possibility of collision between the buckle 31 and the guide buckle hole 121, and realizing reliable assembly of the side frame 30 on the side flange 12.

[0051] Specifically, in an embodiment of the present invention, the second hole segment 124 is higher than the first hole segment 122. Specifically, the upper edge of the first hole segment 122 is located between the upper edge and the lower edge of the second hole segment 124, and the lower edge of the first hole segment 122 is located below the lower edge of the second hole segment 124. On the one hand, it is convenient for the buckle 31 to slide from the first hole segment 122 to the second hole segment 124. On the other hand, it can prevent the buckle 31 from quickly detaching from the second hole segment 124 and sliding to the first hole segment 122 to a certain extent, thereby facilitating the reliable buckle connection of the buckle 31 at the second hole segment 124.

[0052] See also Figure 5When the buckle 31 is in the unlocking state, the lock 31 is locked and the locking nut 31 is unlocked. However, the present design is not limited thereto. In other embodiments, the extending direction of the fastening section 312 of one buckle 31 is opposite to the extending direction of the fastening section 312 of the other buckles 31 .

[0053] Furthermore, in an embodiment of the present invention, the card slot 32 includes a connected card section 321 and a flared section 322, and the flared section 322 is arranged close to the notch of the card slot 32, wherein the surface of the flared section 322 facing the side frame 30 is a guide slope inclined away from the side frame 30. In this way, the setting of the guide slope facilitates the edge of the second hole section 124 to quickly slide along the flared section 322 into and be stuck in the card section 321, thereby completing the clamping and fixing of the card slot 32 to the buckle 31.

[0054] Specifically, in an embodiment of the present invention, the width of the snap-fit ​​section 321 is the same as the thickness of the edge of the second hole section 124 , which helps to improve the snap-fit ​​strength between the snap 31 and the guide snap 31 , thereby improving the connection reliability between the side frame 30 and the side flange 12 .

[0055] See also Figure 3In the embodiment of the present invention, the front edge of the top plate 11 is provided with a front flange 13 extending downward, and the front flange 13 is provided with a second positioning groove 131. The side frame 30 is also provided with a second overlapping portion 33, and the second overlapping portion 33 is overlapped with the second positioning groove 131. It can be understood that through the provision of the second positioning groove 131, on the one hand, as a limiting structure of the side frame 30 on the front flange 13, it is convenient for the side frame 30 to be overlapped on the second positioning groove 131 through the second overlapping portion 33, thereby limiting the further sliding of the side frame 30 on the side flange 12, and reducing the side frame 30 and the side panel at the rear end. 40 The risk of interference occurs, the service life of the side frame 30 is extended, and at the same time, the fixed-point assembly of the side frame 30 on the front flange 13 is completed, which helps to further improve the assembly efficiency and assembly stability of the side frame 30; on the other hand, because the second overlapping portion 33 is embedded in the second positioning groove 131, it can not only reduce the height of the side frame 30 protruding from the front flange 13 and reduce the unevenness of the surface of the front flange 13, but also increase the effective contact area between the front flange 13 and the second overlapping portion 33, thereby enhancing the installation stability and installation reliability of the side frame 30 on the front flange 13, thereby improving the structural strength of the side end of the smoke hood 100.

[0056] Specifically, the depth of the second positioning recess 131 is the same as the thickness of the second overlapping portion 33 , thereby ensuring that the front surface of the second overlapping portion 33 and the front surface of the front flange 13 are located in the same plane, thereby achieving a flat front surface of the cover body 10. Furthermore, the surface of the front stop 21 of the front frame 20 facing the cover body 10 can be flat, which helps to simplify the structure of the front frame 20. However, the present design is not limited to this. In other embodiments, the second overlapping portion 33 protrudes from the front surface of the front flange 13. In this case, the surface of the front stop 21 facing the cover body 10 is provided with an avoidance recess adapted to the second overlapping portion 33.

[0057] Specifically, in an embodiment of the present invention, the second overlapping portion 33 is locked and connected to the front flange 13 by a fastener, wherein the bottom wall of the second positioning groove 131 is provided with a second positioning hole. When the second overlapping portion 33 is overlapped with the second positioning groove 131, the second connecting hole on the second overlapping portion 33 is connected to the second positioning hole, and the fastener can be passed through the second connecting hole and the second positioning hole from front to back in sequence to complete the fastening connection between the second overlapping portion 33 and the front flange 13; at this time, the fastener is configured as a screw.

[0058] See also Figures 1 to 3In an embodiment of the present invention, the front frame 20 is blocked at the front end of the side frame 30, that is, the front frame 20 also includes an extension portion 23 connected to the front stop portion 21, and the extension portion 23 is blocked at the front end of the side frame 30 to hide the second overlapping portion 33 of the side frame 30, the corresponding fasteners and other structures, thereby improving the overall aesthetics of the front end of the smoke hood 100 and facilitating subsequent maintenance and cleaning.

[0059] See also Figure 2 In an embodiment of the present invention, the smoke hood 100 further includes a side panel 40 arranged near the rear end of the top panel 11, the side panel 40 is fixedly connected to the side flange 12, and an auxiliary fixing member 41 inserted into the side frame 30 is provided on the side facing the side frame 30, wherein the auxiliary fixing member 41 extends toward the side frame 30 and has a tendency to extend downwardly. Furthermore, when the side frame 30 slides backward and the buckle 31 is engaged with the guide card hole 121, during this process, the auxiliary fixing member 41 is inserted into the avoidance hole at the rear end of the side frame 30, which can further improve the installation stability of the side frame 30 and the connection reliability of the side frame 30 and the hood body 10.

[0060] The present invention also proposes a range hood, which includes a smoke hood 100. The specific structure of the smoke hood 100 refers to the above embodiment. Since the range hood adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0061] Optionally, in an embodiment of the present invention, a diversion structure is provided in the smoke collecting hood 100 , and the diversion structure includes a fixed portion connected to the smoke collecting hood 100 , and a rotating portion rotatably connected to the fixed portion;

[0062] It can be understood that the technical solution of the present invention is to provide a diversion structure in the oil smoke suction channel to separate the oil smoke suction channel into a left channel and a right channel, thereby effectively reducing the vortex caused by the collision of two streams of oil smoke entering the oil smoke suction channel from both sides of the smoke inlet, improving the smoothness of oil smoke passing through the oil smoke suction channel, thereby improving the suction effect of the range hood and reducing noise; in addition, the diversion structure includes a rotating part, which can be rotated to increase the channel corresponding to the side with a large amount of oil smoke and reduce the channel corresponding to the side with a small amount of oil smoke, thereby improving the oil smoke suction capacity of the channel corresponding to the side with a large amount of oil smoke and reducing the channel corresponding to the side with a small amount of oil smoke. The oil fume suction ability is improved, thereby improving the oil fume suction effect of the range hood; furthermore, the diversion structure also includes a fixed part, which not only provides a mounting support for the rotating part to be rotated, but also has the function of separating the oil fume suction channel, thereby more effectively reducing the vortex caused by the collision of two streams of oil smoke entering the oil fume suction channel from both sides of the smoke inlet, and better improving the smoothness of oil smoke passing through the oil fume suction channel, and the space within the fixed part can also be used to install a driving mechanism for driving the rotating part to rotate, so as to isolate the oil fume for the driving mechanism through the shell of the fixed part, avoid the oil fume from being deposited on the driving structure, and thus extend the service life of the driving mechanism.

[0063] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
