The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] This embodiment provides a range hood for installation in a kitchen environment, specifically above the stove. It is used to promptly exhaust the exhaust gases from the stove and the harmful fumes produced during cooking into a smoke exhaust duct, which then discharges them outdoors. This range hood can be a top-mounted, side-mounted, or ceiling-mounted type. This embodiment uses a side-mounted range hood as an example.

[0045] Please refer to Figure 1 and Figure 2 The range hood includes a filter mounting structure, a main unit housing 1, and a fan 2. The main unit housing 1 is mounted above the casing 3 of the filter mounting structure. The fan 2 is located inside either the main unit housing 1 or the casing 3 of the filter mounting structure. When the fan 2 is operating, under the negative pressure provided by the fan 2, exhaust gases from the stove combustion and harmful fumes generated during cooking can enter the casing 3 through the smoke inlet 35 of the filter mounting structure, and then be discharged into the exhaust duct by the fan 2.

[0046] In related technologies, filters are typically installed at the smoke inlet of a range hood and fixed with screws. However, filters reduce the effective air intake area of ​​the smoke inlet, affecting the air volume and consequently the extraction effect of cooking fumes. Furthermore, fixing the filter with screws reduces the efficiency of its installation and removal.

[0047] To address this issue, this embodiment utilizes a filter installation structure. Specifically, please refer to... Figures 1 to 5The filter installation structure includes a housing 3, a bracket 4, and a filter 5. The housing 3 has an inner cavity 34 and a smoke inlet 35 communicating with the inner cavity 34. The bracket 4 is located in the inner cavity 34 and fixed to the housing 3, and also has a first connecting part 6. The filter 5 is located in the inner cavity 34 and spaced apart from the smoke inlet 35, and has a second connecting part (not shown in the attached drawings). One of the filter 5 and the bracket 4 has a slot 41, and the other of the filter 5 and the bracket 4 is inserted into the slot 41. The first connecting part 6 and the second connecting part are detachably connected. The filter installation structure provided in this embodiment, by placing the filter 5 in the inner cavity 34 and spaced apart from the smoke inlet 35, ensures that the smoke inlet 35 is not blocked by the filter 5. When the fan 2 is working, it can increase the air intake of the smoke inlet 35, thereby improving the suction effect of oil fumes and exhaust gas. In addition, the filter 5 is inserted into the bracket 4, and the filter 5 and the bracket 4 are detachably connected through the first connecting part 6 and the second connecting part, which facilitates the quick assembly and disassembly of the filter 5 and the bracket 4, improving the convenience of assembling and disassembling the filter 5.

[0048] In this embodiment, an exemplary solution is provided where a slot 41 is provided on the bracket 4, and the filter screen 5 is inserted into the slot 41. In other embodiments, a slot 41 may also be provided on the filter screen 5, and the bracket 4 may be inserted into the slot 41 on the filter screen 5.

[0049] In one alternative embodiment, please refer to Figure 1 and Figure 2 The housing 3 includes a smoke collection hood 31, a smoke baffle 32, and a baffle 33. The smoke baffle 32 and the baffle 33 are interconnected and both are connected to the smoke collection hood 31. The smoke baffle 32, the baffle 33, and the smoke collection hood 31 together form an inner cavity 34. The smoke inlet 35 is located on the baffle 33 or is formed by the smoke baffle 32 and the baffle 33. Specifically, the bracket 4 is installed inside the smoke collection hood 31 and is fixedly connected to the smoke collection hood 31. With this configuration, the fumes can undergo kinetic energy redistribution through viscous shearing action on the path from the smoke inlet 35 to the filter screen 5, thereby eliminating airflow disturbance at the smoke inlet 35 and making the wind speed at various positions of the smoke inlet 35 tend to be the same.

[0050] In other embodiments, the housing 3 may also include only a smoke collection hood 31, with the inner cavity 34 and the smoke inlet 35 both located in the smoke collection hood 31.

The top of the baffle 33 is slidably connected to the smoke baffle 32. The smoke baffle 32 can rotate relative to the smoke collection hood 31 and can switch between the working state and the retracted state. When the smoke baffle 32 is in the retracted state, the smoke baffle 32 is located in front of the smoke collection hood 31, and the baffle 33 is located behind the smoke baffle 32 and inside the smoke collection hood 31. At this time, the smoke inlet 35 is blocked, and the space occupied by the housing 3 is minimized. When the smoke baffle 32 switches from the retracted state to the working state, the smoke baffle 32 flips forward relative to the smoke collection hood 31 (front and back direction as shown). Figure 1 (in the direction indicated by the arrow ef), and drive the baffle 33 to move synchronously; when the smoke baffle 32 is in use, the smoke baffle 32 flips forward relative to the smoke hood 31 to the maximum angle. At this time, the smoke baffle 32, the baffle 33 and the smoke hood 31 together form the inner cavity 34, and the smoke baffle 32 is located above the stove and is used to block the rising oil fumes and exhaust gas, so that more oil fumes and exhaust gas can enter the inner cavity 34 through the smoke inlet 35.

[0052] In an optional embodiment, the range hood further includes a linear drive (not shown in the drawings). The body of the linear drive is rotatably connected to the smoke collection hood 31, and the telescopic rod of the linear drive is rotatably connected to the smoke baffle 32.

[0059] In an optional embodiment, a plurality of slots 41 are arranged along the length direction of the filter 5 (the length direction of the filter 5 is as follows). Figure 1 The slots are evenly spaced (as indicated by the arrow ab). In this embodiment, two slots 41 are provided on the bracket 4 as an example. In other embodiments, the number of slots 41 on the bracket 4 can be adjusted according to actual needs.

[0060] In an alternative embodiment, please refer to Figure 4 As the filter 5 is inserted into the slot 41, the width of the slot 41 gradually decreases. This design makes it easy to align the filter 5 and the slot 41 when inserting the filter 5, and the wall of the slot 41 can guide the filter 5 to gradually insert into the slot 41 and ensure that the relative position of the two is stable.

[0061] In an alternative embodiment, please refer to Figure 3 and Figure 4 The slot 41 is V-shaped. In other embodiments, the slot 41 may also be U-shaped, arc-shaped, etc.

[0062] In an alternative embodiment, please refer to Figure 1 and Figure 4 The direction in which the filter screen 5 is inserted into the slot 41 is consistent with the width direction of the filter screen 5, as shown in the following figure. Figure 1 The direction indicated by the middle arrow cd.

[0063] In an alternative embodiment, please refer to Figure 3 and Figure 4 One of the first connecting part 6 and the second connecting part includes a magnet, and the other of the first connecting part 6 and the second connecting part can be magnetically attracted. The first connecting part 6 and the second connecting part are magnetically attracted to each other. With this configuration, when installing the filter screen 5, after the filter screen 5 is inserted into the slot 41, blindly pushing the filter screen 5 towards the side closer to the bracket 4 will cause the first connecting part 6 and the second connecting part to magnetically attract each other, ensuring the connection stability between the filter screen 5 and the bracket 4, and improving the ease of operation for installing and removing the filter screen 5.

[0064] In this embodiment, an exemplary solution is provided where the first connecting part 6 is a magnet, and the second connecting part can be magnetically attracted. In this embodiment, the second connecting part can be a magnet, or made of a material that can be magnetically attracted, or an electromagnet, etc.

[0065] In other embodiments, the first connecting part 6 may be magnetically attracted, and the second connecting part may be a magnet.

[0066] In an alternative embodiment, please continue to refer to Figure 3 and Figure 4 The support 4 has multiple first connecting parts 6 spaced apart, and the filter screen 5 has multiple second connecting parts. The multiple first connecting parts 6 and multiple second connecting parts are detachably connected in a one-to-one correspondence. This arrangement further improves the stability of the connection between the filter screen 5 and the support 4. In this embodiment, an exemplary configuration is provided where the support 4 has two first connecting parts 6 and the filter screen 5 has two second connecting parts. In other embodiments, the number of first connecting parts 6 on the support 4 and the number of second connecting parts on the filter screen 5 can be adjusted according to actual needs.

[0067] In an alternative embodiment, please refer to Figure 4The plurality of first connecting portions 6 on the bracket 4 are spaced apart along the length direction of the filter screen 5. The plurality of second connecting portions on the filter screen 5 are arranged corresponding to the positions of the plurality of first connecting portions 6.

[0073] In an alternative embodiment, please refer to Figure 1 The length of the filter screen 5 is parallel to the length of the smoke inlet 35, and the length of the filter screen 5 is less than the length of the smoke inlet 35. The length of the smoke inlet 35 is as follows: Figure 1 As shown in K1, the length of filter 5 is as follows: Figure 1 As shown in K2, K2 < K1. This arrangement facilitates the filter screen 5 to enter and exit the inner cavity 34 through the smoke inlet 35, thereby facilitating the installation and removal of the filter screen 5.

[0074] In an alternative embodiment, please continue to refer to Figure 1 Along the length of the smoke inlet 35, the filter screen 5 is centered relative to the smoke inlet 35. This arrangement facilitates the filter screen 5's entry and exit from the inner cavity 34 through the smoke inlet 35, thereby further improving the efficiency of filter screen 5's installation and removal.

[0075] In an alternative embodiment, please continue to refer to Figure 1 , Figure 3 and Figure 5 The filter installation structure also includes a handheld part on the filter 5. This design allows operators to easily move the filter 5 using the handheld part when installing or removing it, further improving the convenience of filter 5 installation and removal.

This embodiment exemplarily provides a handle including two handle holes 51 spaced apart from each other on the filter screen 5. The spacing between the two handle holes 51 is as follows: Figure 1 As shown in K3, K3 < K2. In other embodiments, the number and spacing of the handle holes 51 included in the hand grip can be set according to actual needs.

[0077] In other embodiments, the hand-held part may also include a handle groove provided in the filter screen 5, or a carrying handle, etc.

[0078] In an alternative embodiment, please continue to refer to Figure 1 Along the length of the filter screen 5, the handle is centered relative to the filter screen 5. Specifically, in this embodiment, the two handle holes 51 of the handle are symmetrically distributed relative to the filter screen 5 along the length of the filter screen 5. This arrangement further facilitates the filter screen 5 entering and exiting the inner cavity 34 through the smoke inlet 35 and improves the ease of operation for assembling and disassembling the filter screen 5.

[0079] It should be noted that in other embodiments, when the hand-held part includes a different number of hand-holding holes 51, the distribution of the hand-holding holes 51 can be set according to actual needs. For example, when the hand-held part includes one hand-holding hole 51, the hand-holding hole 51 is centered relative to the filter screen 5 along the length of the filter screen 5. When the hand-held part includes four hand-holding holes 51, the four hand-holding holes 51 are divided into two groups, and the two groups are symmetrically distributed relative to the filter screen 5 along the length of the filter screen 5.

[0080] In an alternative embodiment, please continue to refer to Figure 1 Along the width of the filter screen 5, the handle is centered relative to the filter screen 5; this arrangement further facilitates the filter screen 5 to enter and exit the inner cavity 34 through the smoke inlet 35 and improves the ease of operation of disassembling and assembling the filter screen 5.
