[0032] In the field of modern kitchen appliances, the performance and structural design of range hoods are crucial to the user experience. The installation structure of the side baffle assembly not only affects the aesthetics of the range hood's side profile but also has a close relationship with its overall appearance. This embodiment will describe in detail a side baffle assembly installation structure applied to a range hood and its specific implementation within the range hood.

[0033] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0034] like Figures 5 to 7The diagram shows the overall structure of a range hood, including a main body 1 and side baffle assemblies connected to the lower sides of the main body 1. The main body 1 includes an upper air collection box, a lower top plate 11, and a back plate 2 located behind the top plate 11. A fan is installed in the air collection box to provide the power required for the flow of oil droplets in the range hood. An air inlet communicating with the air collection box is located in the center of the bottom surface of the top plate 11. When the fan is started, it generates negative pressure inside the range hood, driving airflow, and the fumes in the kitchen are drawn into the air collection box through the air inlet and discharged. The back plate 2 is connected to the rear side of the main body 1, and the side baffle assemblies are connected to the two sides of the bottom of the top plate 11. The area between the two side baffle assemblies is the ventilation area, and the side baffle assemblies play a role in blocking and guiding the fumes to a certain extent. However, in existing technologies, the side baffle assembly is integrally molded and connected to the back panel 2 and top panel 11. Some range hoods have detachable side baffle assemblies, which are manufactured independently and then connected to the back panel 2 and top panel 11 via bonding or splicing. However, this detachable connection method in existing technologies generally suffers from poor stability, and the side baffle assembly is prone to loosening at the connection points, resulting in aesthetic defects and affecting the user experience. The purpose of this invention is to provide a detachable structure for the side baffle assembly and the range hood body, ensuring a secure connection with the top panel 11 and back panel 2.

[0035] Both the top plate 11 and the back plate 2 are plate-shaped structures. The top plate 11 is horizontally positioned at the bottom of the main body 1 of the range hood; the back plate 2 is vertically positioned and connected to the rear side of the top plate 11. First connecting members 21 are provided on the left and right sides of the back plate 2. The first connecting members 21 are roughly strip-shaped structures used to position the side baffle assembly. A [missing information - likely a device or component] is connected to each of the bottom sides of the top plate 11. Figures 1 to 3 The side baffle assembly shown includes a side baffle body 3, which is generally a plate structure with an upper edge and a rear edge. The upper edge is horizontally positioned opposite the top plate 11, and the rear edge is vertically positioned opposite the back plate 2. The side baffle assembly also includes a second connector 31, which is positioned along the edge of the side baffle body 3. Each side baffle body 3 is connected to the top plate 11 and the first connector 21 respectively via the second connector 31.

[0036] Specifically, the second connector 31 includes an upper connecting portion along the upper edge of the side baffle body 3 and a rear connecting portion along the rear edge of the side baffle body 3. The side baffle body 3 is connected to the top plate 11 via the upper connecting portion and to the first connector 21 on the back plate 2 via the rear connecting portion. The second connector 31 is a detachable structure. During installation, both the upper and lower connecting portions are positioned relative to the top plate 11 and the back plate 2 to determine the installation position of the side baffle body 3. The width of the second connector 31 is greater than the width of the side baffle body 3, enabling it to connect to the top plate 11 and back plate 2 of the main body 1 of the range hood instead of the side baffle body 3. This avoids directly machining connecting parts on the side baffle body 3, which could cause warping of the surface of the side baffle body 3 and affect its appearance and connection strength.

[0037] The second connector 31 is provided with connecting structures that cooperate with the top plate 11 and the first connector 21. By setting the connecting structures on the second connector 31, the side baffle body 3 only needs to be set as a plate structure without affecting the size of the side baffle body 3 itself, thereby expanding the design space of the connecting structure. In this embodiment, the upper connecting part and the top plate 11 are connected by a snap-fit ​​connection, including a snap-fit ​​part 311 on the surface of the upper connecting part opposite to the top plate 11, and a slot on both sides of the bottom of the top plate 11 corresponding to the snap-fit ​​part 311; it also includes a snap-fit ​​member 4 set above the top plate 11 of the smoke machine body 1, the snap-fit ​​interface of the snap-fit ​​member 4 is aligned with the slot, the snap-fit ​​part 311 passes through the slot and snaps with the snap-fit ​​member 4, and the connection position of the snap-fit ​​part 311 is restricted to the upper space of the top plate 11 by the snap-fit ​​member 4. The shape of the snap-fit ​​part 311 can be hook-shaped, buckle-shaped, ring-shaped, etc., and the snap-fit ​​member 4 can be a matching groove, protrusion, etc., set above the top plate 11. The latching part 311 protrudes from the upper surface of the upper connecting part. When the latching part 311 extends from the slot into the interface, the upper surface of the upper connecting part is opposite to the lower surface of the top plate 11, ensuring a consistent and uniform appearance for the range hood. The latching part 311, slot, and connector 4 are easy to position, and their number is not limited to one set. Multiple latching parts 311 can be set along the upper connecting part, and multiple latching parts 311 at different positions can simultaneously position the side baffle assembly to achieve quick positioning and support of the side baffle assembly.

[0038] The advantage of the snap-fit ​​structure lies in the rapid positioning of the installation position. To enhance the connection strength, the end face of the upper connecting part opposite to the top plate 11 is provided with at least one first threaded connection position 312. The first threaded connection position 312 is provided with a threaded fastener, which can be a conventional connecting element such as a screw or bolt. The upper connecting part is fixed to the surface of the bottom plate by means of threaded connection. The threaded fastener is preferably located on the side of the snap-fit ​​part 311. After the snap-fit ​​part 311 snaps into the snap-fit ​​member 4, the entire upper connecting part is fixedly connected to the bottom of the top plate 11.

[0039] The first threaded connection 312 can be positioned above the upper edge of the side baffle body 3 along the upper connection portion. Alternatively, as in this embodiment, the end of the upper connection portion away from the rear connection portion extends beyond the upper edge of the side baffle body 3, and a first connection hole for connecting to the top plate 11 is provided in the extended portion. A second connection hole 111 is provided at the bottom of the top plate 11 corresponding to the position of the first connection hole. A threaded fastener is installed in the first connection hole, and the threaded fastener passes through the first connection hole and the second connection hole 111 to connect the side baffle body 3 to the top plate 11. Since the first connection hole is located outside the extended area of ​​the upper edge of the side baffle body 3, and the bottom of this extended area is not blocked by the side baffle body 3, this means that the installation of the threaded positioning component will not affect the side baffle body 3. This design allows for the selection of a larger positioning component, and the thickness of the side baffle body 3 can be designed to be much smaller than the size of the first connecting component 21, thereby effectively reducing the weight and volume of the side baffle body 3 and optimizing the lightweight design of the overall structure.

[0040] Similar to the connection between the upper connecting part and the top plate 11, the rear connecting part and the back plate 2 are also provided with a mating connection structure. The rear connecting part has a second threaded connection position 313 facing the second connecting member 31. A third connecting hole is opened on the second connecting member 31 at the position corresponding to the second threaded connection position 313. A threaded fastener is installed in the third connecting hole, and the rear connecting part is fixed to the front side of the back plate 2 by a threaded connection. As a further embodiment of this utility model, the first threaded connection position 312 is located at the front end of the upper connecting part extending from the upper edge of the side baffle body 3, and the second threaded connection position 313 is located at the end of the rear connecting part away from the upper connecting part and extends out of the rear edge of the side baffle body 3. The second threaded connection position 313 can also achieve the function of avoiding the side baffle body 3 and correspondingly connecting with the first connecting member 21.

[0041] As a further embodiment of this utility model, the rear connecting portion of the second connector 31 is provided with a first connecting groove 314 on the side facing the back plate 2. The first connecting groove 314 is a groove-shaped structure extending along the length direction of the rear connecting portion and extending in the same direction as the first connector 21. The first connector 21 is accommodated in the first connecting groove 314, and the first connector 21 can be connected to the two groove sides of the first connecting groove 314 by bonding, pressing, or other methods. This connection not only enhances the connection strength between the side baffle assembly and the back plate 2, but also, since the connection position is located inside the first connecting groove 314, the non-connecting portion of the first connector 21 facing away from the first connecting groove 314 can be set to a relatively smooth and flat surface, consistent with the overall shape of the range hood, thus enhancing its aesthetics.

[0042] like Figure 3 and Figure 4As shown, the two sides of the first connecting groove 314 are further configured as an asymmetrical structure. The width of the outer groove side of the first connecting groove 314 away from the first connector 21 is set to be greater than the width of the inner groove side. The first connector 21 is connected to both sides of the back plate 2. During installation, the first connector 21 extends from the inner groove side into the first connecting groove 314, and the outer side of the first connector 21 abuts against the inner wall of the outer groove side of the first connecting groove 314. The inner groove side of the first connecting groove 314 is further configured as a support side extending away from the outer groove side. When the first connector 21 is installed in the first connecting groove 314, the side of the back plate 2 connected to the side baffle body 3 abuts against this support side. This support side can increase the contact area between the back plate 2 and the second connecting part, providing a certain support force for the back plate 2 after connection, and enhancing the connection reliability between the back plate 2 and the side baffle body 3.

[0043] As a further embodiment of this utility model, the second connector 31 has a second connecting groove 315 on the side facing the side baffle body 3. The second connecting groove 315 is a U-shaped opening on one side, with its opening direction facing the side baffle body 3. The upper edge and rear edge of the side baffle body 3 are connected to the mounting groove. The shape and size of the mounting groove are adapted to the side baffle body 3, and the two groove edges of the mounting groove form a connecting surface connected to the side baffle body 3. In the scheme of bonding the side baffle assembly to the second connector 31, the side baffle body 3 is connected to the mounting groove, and the adhesive position is blocked by the two groove edges of the second connecting groove 315. No adhesive traces are visible from either the inside or the outside, and the second connector 31 can maintain the overall appearance consistency of the entire range hood. At the same time, the side baffle body 3 is connected to the bottom and two groove edges of the second connecting groove 315, which can increase the contact area between the side baffle body 3 and the second connector 31, thereby enhancing the connection tightness between the side baffle body 3 and the second connector 31.

[0044] As a specific embodiment of this utility model, it also includes a reinforcing member 32. The reinforcing member 32 and the second connecting member 31 are designed separately, and the reinforcing member 32 is disposed in the second connecting groove 315 and connected between the second connecting member 31 and the side baffle body 3. Its structure is roughly U-shaped, which is adapted to the groove edge and bottom of the second connecting groove 315. The function of the reinforcing member 32 is to distribute the pressure borne by the side baffle body 3 and the second connecting member 31, and prevent deformation due to excessive pressure. At the same time, the reinforcing member 32 can provide additional support for the side baffle body 3 and the second connecting member 31, making the connection between the second connecting member 31 and the side baffle body 3 more stable, and enhancing the overall structural strength and connection stability of the side baffle assembly. The reinforcing member 32 can be formed by connecting the three sides of the U shape separately, or it can be set as two separate structures, each of which contains an angular structure, and then the two angular structures are spliced ​​together.

[0045] As a specific embodiment of this utility model, one end of the reinforcing member 32 also extends out of the front edge of the side baffle body 3. A third threaded connection position 321 is provided at the position corresponding to the first threaded connection position 312. A fourth connection hole is provided at the third threaded connection position 321, and a threaded fastener is installed in the fourth connection hole. The threaded fastener passes through the third threaded connection position 321 on the reinforcing member 32 and the first threaded connection position 312 on the second connecting member 31 in sequence and is then connected to the top plate 11. While fixing the position of the second connecting member 31, the reinforcing member 32 is quickly positioned, and the positions of the reinforcing member 32 and the second connecting member 31 are relatively fixed.

[0046] The side panel assembly also includes a decorative cover 5, located at the portion of the second connector 31 extending beyond the front edge of the side panel body 3. This location is the connection point with the top plate 11. The interior of the decorative cover 5 forms a receiving space that can conceal the threaded fasteners at this connection point, thereby improving the aesthetics and consistency of the overall structure. This not only effectively prevents the threaded fasteners from being exposed but also further enhances the connection strength between the second connector 31 and the side panel body 3, providing additional support for both.

[0047] The decorative cover 5 also has a U-shaped structure, with its internal space designed to accommodate the threaded positioning component. The second connector 31 has slots 33 on both sides of its leading edge, and the decorative cover 5 has a corresponding latch 51 at each slot 33. The latches 51 and slots 33 interlock, ensuring a secure installation of the decorative cover 5. The design of the decorative cover 5 ensures that the first threaded connection 312 and the third threaded connection 321 are within its enclosure. This design not only completely conceals the connection points but also enhances the overall structural stability and aesthetics, resulting in a cleaner and more unified appearance for the side panel assembly.

[0048] The assembly process of the side baffle assembly in this embodiment can be summarized as follows: Reinforcing members 32 are inserted into the upper and rear edges of the side baffle body 3, and then inserted into the second connecting member 31 along with the reinforcing members 32. The upper connecting portion of the second connecting member 31 is connected to the top plate 11 via the snap-fit ​​portion 311 and the first threaded connection position 312, and the rear connecting portion is connected to the back plate 2 via the third threaded connection position 321 and the first connecting groove 314. Finally, a decorative cover 5 is inserted at the first threaded connection position 312, thus completing the assembly of the side baffle body 3 and the range hood.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
