[0026] like Figure 1 and Figure 2 As shown, the range hood provided by this utility model may include a fan assembly 1, a first drive mechanism, and a movable smoke collection hood 2. The fan assembly 1 can be embedded and installed inside the wall cabinet, and after embedding and installation, the exposed bottom plane of the fan assembly 1 can be flush with the bottom of the wall cabinet.

[0027] The fan assembly 1 includes a fan housing, a fan, and a first control system, both of which are located inside the fan housing. The movable smoke hood 2 is movably connected to the fan housing via a first drive mechanism, for example, by sliding or rotating. In this embodiment, the first drive mechanism drives the movable smoke hood 2 into or out of the fan housing. In other possible implementations, the range hood may include the fan assembly 1 and the smoke hood, with the smoke hood and fan assembly 1 fixedly connected, meaning they do not move relative to each other.

[0028] The movable smoke hood 2 has a smoke inlet. After it is moved out of the fan housing, it switches to the working state. The oil fumes entering through the smoke inlet pass through the movable smoke hood 2 and the fan housing before entering the fan.

[0029] In this embodiment, the fan assembly 1 includes a housing 11, a base plate 111, and a first control system. The housing 11 is used to accommodate the fan. The front side of the bottom of the housing 11 has a rectangular opening, and an accommodating area is formed inside the opening. The base plate 111 is detachably connected to the housing 11, and the base plate 111 and the accommodating area form an accommodating cavity, in which the first control system is installed. The base plate 111 is installed in the rectangular opening at the bottom of the housing 11, and its periphery is covered by the housing 11. The bottom of the base plate 111 is flush with the bottom of the housing 11, and a mounting hole for the movable smoke collection hood 2 to pass through is provided at the rear side of the opening.

[0030] like Figure 8 As shown, the first control system is mounted on the inner wall of the base plate 111. During assembly, the first control system and the base plate 111 can be connected as a whole before being connected to the cover 11. During disassembly, the first control system is removed from the cover 11 after the base plate 111 is taken off.

[0031] like Figure 8 As shown, the first control system can be fixed to the base plate 111 via a bracket. Specifically, in this embodiment, the first control system includes a first control device 21 and a second control device 22. The first control device 21 and the second control device 22 are used to perform different functions. In this embodiment, the first control device 21 is a switch device that can control the opening and closing of the range hood. The second control device 22 is a gesture control device. The trigger structure of the gesture control device is a first window. The user waves their hand below the window to activate the gesture control device, thereby activating other functions of the range hood.

[0032] like Figures 8-10As shown, a first bracket 112, a second bracket 113, and a third bracket 114 are arranged sequentially and spaced apart along the left-right direction on the base plate 111. The first bracket 112 and the third bracket 114 are symmetrically designed and are bonded to the back of the glass using an adhesive, such as silicone sealant. A first control device 21 is located between the first bracket 112 and the second bracket 113 and is connected to both the first bracket 112 and the second bracket 113. A second control device 22 is located between the second bracket 113 and the third bracket 114 and is connected to both the second bracket 113 and the third bracket 114. Both ends of the first control device 21 and the second control device 22 are fixed, ensuring connection stability.

[0033] Taking the first control device 21 as an example, both the left and right ends of the first control device 21 are connected to the first bracket 112 and the second bracket 113 through the second locking member. Specifically, taking the first control device 21 as an example, both the left and right ends of the first control device 21 are provided with first through holes, and both the first bracket 112 and the second bracket 113 are provided with second through holes. The two first through holes and the two second through holes are aligned. Using the two second locking members, such as screws, the first control device 21 can be locked to the first bracket 112 and the second bracket 113 respectively. Similarly, the second control device 22 is fixed.

[0034] The fan assembly 1 also includes a lamp body 23, which is located on the front or rear side of the second bracket 113. The left and right ends of the lamp body 23 are connected to the first bracket 112 and the third bracket 114 respectively, achieving a stable connection of the lamp body 23. The area on the base plate 111 corresponding to the lamp body 23 is set as a transparent window, and the back of the base plate 111 is not screen-printed with ink to facilitate light transmission.

[0035] The lamp body 23 can be used for illumination or as an ambient light, and the area on the base plate 111 corresponding to the lamp body 23 is light-transmitting. In this embodiment, the lamp body 23 is located behind the first control device 21 and the second control device 22, and the left and right ends of the lamp body 23 are fixed.

[0036] To achieve precise positioning during installation, a first stop structure 115 is provided on the first bracket 112, and a second stop structure 116 is provided on the third bracket 114. Both the first stop structure 115 and the second stop structure 116 can be vertically positioned baffles, with the distance between the two baffles being the length of the lamp body 23. The two baffles respectively stop and limit the lamp body 23 on its left and right sides. Correspondingly, a front stop structure 117 and a rear stop structure 118 are provided on the front and rear sides of the lamp body 23. The front stop structure 117 and the rear stop structure 118 are also baffles, with the distance between them being the width of the lamp body 23. The first stop structure 115, the second stop structure 116, the front stop structure 117, and the rear stop structure 118 achieve horizontal positioning of the lamp body 23, preventing it from moving horizontally after installation.

[0037] Finally, to fix the lamp body 23, an upper stop structure 119 can be set. The upper stop structure 119 is a horizontally set baffle. The upper stop structure 119 and the base plate 111 are located on the upper and lower sides of the lamp body 23, respectively, and stop and limit the lamp body 23 on the upper and lower sides to prevent the lamp body 23 from moving vertically. The upper stop structure 119 can be set alone, or it can be connected with one or more of the first stop structure 115, the second stop structure 116, the front stop structure 117 and the rear stop structure 118 to form an "L"-shaped baffle that limits movement in two directions. During assembly, the upper stop structure 119 is formed by bending.

[0038] like Figure 6 and Figure 11 As shown, to prevent the first control system from being affected by oil contamination, the bottom surface of the housing 11 can be bent upwards to form a receiving groove 241. The first control system is located below the receiving groove 241, and the fan is located inside the housing 11, above the bottom surface of the housing 11. The receiving groove 241 separates the first control system from the fan, completely separating the area accommodating the fan from the area accommodating the first control system, thus reducing the impact of oil contamination on the first control system.

[0039] When the base plate 111 is closed, the bottom surface of the cover 11 is flush with the bottom surface of the base plate 111, improving flatness and making it easier to wipe and clean the entire surface.

[0040] One side of the base plate 111 is inserted into the cover 11, and the other side of the base plate 111 is locked to the cover 11.

[0041] like Figure 7 As shown, in this embodiment, a rearwardly extending connector 242 is provided on the front side of the cover 11, and a slot corresponding to the connector 242 is provided on the base plate 111.

[0042] Specifically, the cover 11 includes a front panel. The lower edge of the front panel has a first folded edge that folds upward and extends vertically upward. The upper edge of the first folded edge has a second folded edge that folds backward and extends horizontally backward. The second folded edge forms a connector 242, which is higher than the bottom surface of the cover 11. The upper surface of the base plate 111 has a suspension portion 243 connected to the base plate 111. A portion of the suspension portion 243 is higher than the base plate 111 and forms a slot with the base plate 111. Specifically, in this embodiment, the suspension portion 243 is disposed on the second bracket 113.

[0043] like Figure 3 , Figure 5 and Figure 8 As shown, a locking tongue 252 protruding rearward from the base plate 111 is provided, and the locking tongue 252 has a first locking hole. A second recessed platform 251 connected to the receiving groove 241 is provided on the bottom surface of the cover 11. The depth of the second recessed platform 251 is greater than or equal to the thickness of the locking tongue 252. The second recessed platform 251 is used to accommodate the locking tongue 252, and a second locking hole corresponding to the first locking hole is provided on the second recessed platform 251. The fan assembly 1 also includes a first locking member 253, such as a locking screw. During installation, the connector 242 is first inserted into the slot, and then the base plate 111 is rotated around the insertion position until the locking tongue 252 enters the second recessed platform 251. Then, the first locking member 253 passes through the first locking hole and the second locking hole to lock the base plate 111 to the cover 11, thereby fixing the front and rear ends of the base plate 111.

[0044] like Figure 8 As shown, in order to simplify the structure, in this embodiment, the locking tongue 252 is provided on the first bracket 112 and the third bracket 114, while the suspension part 243 is provided on the second bracket 113, without the need for additional brackets.

[0045] like Figures 3-5 As shown, to prevent the first locking member 253 from being exposed, the fan assembly 1 also includes a shielding cover 254 connected to the housing 11 and enclosing the second recessed platform 251. After the shielding cover 254 is connected to the housing 11, the bottom surface of the shielding cover 254 can be flush with the base plate 111, improving the overall flatness.

[0046] The second recessed platform 251 is provided with an insertion hole 255, and the cover 254 is provided with an insertion post 256, which is inserted into the insertion hole 255. The insertion post 256 can be made of rubber or plastic. After aligning the insertion post 256 with the insertion hole 255, the cover 254 is pressed upward, and the insertion post 256 can be interference-fitted with the insertion hole 255, thereby fixing the cover 254. Furthermore, the head of the insertion post 256 has a guide round head, and an annular groove can be provided below the guide round head. The thickness of the plate of the cover 11 is less than or equal to the width of the annular groove. When the insertion post 256 is inserted, the annular groove engages with the cover 11, achieving a stable fixed connection.

[0047] The top surface of the cover 254 is provided with a clearance hole 257 to avoid the first locking member 253. By providing the clearance hole 257, the head of the first locking member (e.g., locking screw) is prevented from affecting the installation of the cover 254.

[0048] like Figure 11 As shown, a stop 258 is provided on the rear side of the groove wall, which is on the same side as the second recessed platform 251, in the receiving groove 241. The stop 258 is used to abut against the bottom plate 111 when the bottom surface of the bottom plate 111 is flush with the bottom surface of the cover 11. The main body of the stop 258 can be an L-shaped sheet metal, one end of which is welded to the cover 11, and the other end is flush with the upper surface of the bottom plate 111. This can provide additional support when the bottom plate 111 is subjected to external force, thereby solving the problem of its easy large deformation due to insufficient rigidity.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
