Technical Field
[0001] This utility model relates to the field of range hood technology, specifically to a side baffle sealing structure and a range hood. Background Technology
[0002] A range hood, also known as a cooking hood, is a kitchen appliance designed to purify the kitchen environment. Installed above the stove, it quickly removes combustion waste and harmful fumes produced during cooking, venting them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions. A range hood typically consists of an upper air collection box and a lower baffle housing. The baffle housing is usually composed of a front panel, back panel, and top cover, forming a smoke collection chamber that communicates with the air collection box. Side baffle assemblies are installed on both sides of the smoke collection chamber to guide the flow of fumes to the user side. The side baffle assemblies are usually connected to the range hood body via a snap-fit structure. A connection hole is provided on the front panel, with a connector above the hole. The connector's internal cavity communicates with the connection hole, and hooks that extend into the cavity through the connection hole are provided on the side baffle assembly. The connectors are typically made of plastic. To facilitate demolding, they have demolding ports that connect to the connecting cavity. During the operation of the range hood, the fan blades rotate, guiding airflow. Some oil droplets are thrown out by the airflow generated by the fan rotation. When these droplets collide with the top cover of the smoke collection cavity, they bounce back and easily splash onto the connectors. After prolonged use, oil droplets enter the connecting cavity through the demolding ports of the connectors and then seep into the side baffle assembly from above the connecting holes, resulting in a deterioration in the user experience.

[0031] 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:
[0032] This utility model discloses a side baffle sealing structure for a range hood. Please refer to [link / reference]. Figure 1 and Figure 2 The range hood includes a main body 1 and side baffle assemblies 3 connected to both sides of the main body 1. The main body 1 includes an upper air collection box and a lower shell structure. A fan is installed in the air collection box to provide the power required for the flow of oil droplets in the range hood. When the fan is started, it will generate negative pressure in the range hood, which will drive the air to flow. The shell structure is connected to the lower part of the air collection box and communicates with the air collection box to guide the kitchen oil droplets to flow into the upper air collection box and be discharged.
[0033] Specifically, the shell structure consists of, for example, Figure 1The front panel 11, back panel 17, top cover 15, side panels 18, and two side baffle assemblies 3 are arranged together. The top cover 15 is located at the bottom of the air collection box, the back panel 17 is located behind the front panel 11, and the side panels 18 are connected to the front panel 11 and the back panel 17 on both sides. The back panel 17, front panel 11, side panels 18, and top cover 15 form a smoke collection chamber 12 that communicates with the air collection box. Some of the oil droplets and dust that are not discharged from the air collection box will remain in the smoke collection chamber 12. The two side baffle assemblies 3 are connected to the left and right sides of the front panel 11, expanding the air guiding area of the smoke hood. The front panel 11 has a smoke inlet in the middle. With the front panel 11 facing the back panel 17 as the front side, when the range hood body 1 is in use, the front panel 11 assembly and the side baffle assembly 3 form an opening area facing the user below the range hood body 1. The oil fumes generated in the kitchen will enter the air collection box through the smoke inlet and the smoke collection chamber 12 through this opening area.
[0034] The side baffle assembly 3 is connected to the front panel 11 via a snap-fit or fastening structure. First connecting holes 111 are respectively opened on the left and right sides of the front panel 11, and each side baffle assembly 3 is provided with a hook 31 extending into the first connecting hole 111. The connection principle between the hook 31 and the first connecting hole 111 is that the hook 31 extends into the first connecting hole 111 and snaps into the smoke collection chamber 12. This snap-fit structure is existing technology, and the specific structure of the hook 31 will not be described here. After prolonged use, some oil droplets collected in the smoke collection chamber 12 will accumulate on the front panel 11. When the hook 31 is connected to the front panel 11, it needs to extend into the first connecting hole 111. The accumulated oil and oil droplets in the smoke collection chamber 12 will seep out from the first connecting hole 111, affecting both the appearance of the range hood and the user experience. Therefore, this utility model provides a hook 31 for each set of first connecting holes 111 within the smoke collection chamber 12. Figure 2 The connector 2 shown is attached to the top of the front panel 11 and covers the first connecting hole 111, isolating the upper part of the first connecting hole 111 from the smoke collection chamber 12. The connector 2 is generally a shell structure, containing an internally hollow connecting cavity 21 and a second connecting hole 22. The second connecting hole 22 is located below the connecting cavity 21 and communicates with it, and is correspondingly positioned to correspond to the first connecting hole 111. The hooks 31 of the side baffle assembly 3 can sequentially pass through the first connecting hole 111 and the second connecting hole 22 and engage in the connecting cavity 21 to fix the position of the side baffle.
[0035] The number of connections for the first connecting hole 111, the second connecting hole 22, and the hook 31 can be set to only one set, located in the middle of the front panel 11. Alternatively, multiple sets can be set at various locations along the front-rear extension direction of the front panel 11, thereby quickly locating the installation position of the side baffle assembly 3.
[0036] Figures 3 to 6A range hood including the aforementioned connector 2 is shown. An air collection box housing the exhaust fan is located at the top of the range hood, with its lower portion extending into the smoke collection chamber 12, connecting the smoke collection chamber 12 to the exhaust area of the exhaust fan. The front panel 11 has an approximately L-shaped cross-section, comprising a first part 11a, a second part 11b, and a third part 11c arranged sequentially from top to bottom. The first part 11a extends from front to back, the second part 11b extends from top to bottom, and the third part 11c is arc-shaped, transitioning between the first part 11a and the second part 11b, serving to connect them. First connecting holes 111 are located on the lower sides of the first part 11a. Through the mating structure of the connector 2, the side baffle assemblies 3 are installed on both sides of the front panel 11.
[0037] In this embodiment, the connector 2 is a plastic product, manufactured using injection molding. The connector 2 includes a bottom edge located below the connecting cavity 21, and a second connecting hole 22 is disposed on the bottom edge and communicates with the connecting cavity 21. For the molding of the second connecting hole 22, the entire shape of the bottom edge of the connecting cavity 21 can be machined first, then the second connecting hole 22 can be molded on the bottom edge of the connecting cavity 21, and then the second connecting hole 22 and the first connecting hole 111 can be aligned. Alternatively, referring to the method described in this embodiment, the connecting cavity 21 structure including the second connecting hole 22 can be molded in one step.
[0038] To facilitate the one-time molding of the connecting cavity 21, the connecting part 2 is also provided with a mold release hole 24. The mold core involved in the molding can extend into the mold release hole 24 and the second connecting hole 22, restricting the inner surface shape of the connecting cavity 21, allowing the injection molded material to be quickly molded in one step during the molding stage. After molding is completed, the mold core involved in the molding then exits from the mold release hole 24 and the second connecting hole 22, which is simple and convenient. The mold release hole 24 can be set on the top edge of the connecting cavity 21, forming an upper and lower opposing structure with the second connecting hole 22. See also... Figure 2The ejector hole 24 is positioned on one side of the connecting cavity 21, extending outward from and communicating with the connecting cavity 21. The first advantage of this arrangement is that it facilitates the connection between the connector 2 and the side baffle assembly 3. The ejector hole 24, extending from the side of the connecting cavity 21, forms an opening area on the side of the connecting cavity 21. The hook 31 on the side baffle assembly 3 can extend into the connecting cavity 21 through the first connecting hole 111 and the second connecting hole 22 and be partially accommodated in this opening area, thereby fixing the position of the side baffle assembly 3. The hook 31 and the ejector hole 24 can be configured as an interference fit structure, with the end size of the hook 31 larger than the size of the ejector hole 24. The movement of the hook 31 is restricted by the elasticity of the ejector hole 24, ensuring that the ejector hole 24 provides sufficient resistance to the hook 31 after installation, preventing the hook 31 from falling off. Alternatively, a snap-fit structure that mates with the end of the hook 31 can be provided at the ejector hole 24, such as a protrusion, groove, or retaining ring, to restrict the position of the hook 31. The snap-fit structure at the ejector hole 24 should be easily formed within the connecting cavity 21. This approach effectively utilizes the space where the ejector hole 24 is located, reducing the processing difficulty of the connecting cavity 21.
[0039] The second advantage of placing the mold hole 24 on the side of the connecting cavity 21 is that it can reduce the leakage of oil droplets in the smoke collection cavity 12. The smoke collection cavity 12 of the range hood is connected to the upper air collection box area. Especially when the upper cavity of the range hood is a single layer, the upper cavity of the range hood will also form a smoke collection area. When the fan in the air collection box is working, the location of the connector 2 installed in the smoke collection cavity 12 is close to the exhaust fan in the air collection box. When the oil thrown out by the exhaust fan impeller hits the top cover 15 of the smoke collection cavity 12, it bounces back and easily splashes onto the connector 2. Then, it enters the connecting cavity 21 through the mold hole 24 on the top of the connector 2. After long-term use of the range hood, the oil flows along the side baffle of the connecting cavity 21, affecting the user experience. By opening the mold hole 24 on the side of the connecting cavity 21, the top edge of the connecting cavity 21 can be set as a completely covered closed structure, reducing the amount of oil droplet splashing and seepage.
[0040] According to a further embodiment, the connector 2 has connecting portions 23 on both sides, extending outward from both sides of the bottom edge of the connecting cavity 21. The connecting portions 23 are used to connect to the upper surface of the front plate 11, allowing the connector 2 to remain stably within the smoke collection cavity 12. The connecting portions 23 are located on both sides of the connecting cavity 21, avoiding the positions where the hook 31 passes through the second connecting hole 22 and the first connecting hole 111, thus reducing interference with the connection of the hook 31. Simultaneously, the fixed connecting portions 23 support the connecting cavity 21 from both sides, increasing the connection stability of the central connecting cavity 21. The connection part 23 can be fixed to the front plate 11 by conventional connection methods such as threaded connection, riveting, snap-fit, and sleeve. In this embodiment, the threaded connection method is used. Each connection part 23 is provided with a set of third connection holes 232. The front plate 11 is provided with a fourth connection hole 112 corresponding to the position of each set of third connection holes 232. Threaded connectors are installed at the third connection holes 232 and the fourth connection holes 112. The threaded connectors pass through the fourth connection holes 112 and the third connection holes 232 in sequence to fix the connector 2 to the front plate 11.
[0041] According to a further embodiment, each connecting part 23 is provided with an upwardly extending connecting post 231, and a third connecting hole 232 extends upward along the connecting post 231 from the bottom. The threaded connector passes through the fourth connecting hole 112 and extends into the third connecting hole 232 of the connecting post 231. The connecting post 231 can position and guide the connection position of the threaded connector 2, strengthening the stable connection between the connecting seat and the front plate 11. The fourth connecting hole 112 is further configured as a countersunk hole. After the threaded connector is installed, the head of the threaded connector is embedded in the countersunk hole, ensuring the flatness of the bottom plane of the front plate 11, and preventing the threaded connector from being exposed and damaged by accidental contact during use.
[0042] According to a further embodiment, a shielding member 13 is provided inside the smoke collection chamber 12. The shielding member 13 is positioned above the connector 2 and covers the first connecting hole 111. When the oil ejected by the impeller of the exhaust fan collides with the top cover 15 of the smoke collection chamber 12, it bounces back and drips onto the shielding member 13. The shielding member 13 can block the oil, preventing it from dripping onto the connector 2, thereby preventing the oil from entering the connecting chamber 21 from the demolding port of the connector 2. The shielding member 13 can be configured as a block structure similar in size to the connector 2 to provide targeted protection above the connector 2; it can also be configured as... Figure 3 The plate-like structure shown extends along the length of connector 2, fully covering the upper surface of connector 2, preventing oil from dripping onto the top of connector 2.
[0043] Specifically, the shielding member 13 is disposed within the smoke collection chamber 12 and extends along the front-rear direction of the front plate 11. Oil baffles 14 are also provided on both sides of the front plate 11. These oil baffles 14 are also plate-shaped and extend along the front-rear direction of the front plate 11. The first connecting hole 111 is located outside the oil baffle 14, isolating the connection point between the hook 31 and the first connecting hole 111 in a region closer to the outer side in the left-right direction, away from the main working area of the central fan. The shielding member 13 isolates oil droplets above the connector 2, and the oil baffle 14 isolates oil droplets inside the connector 2. The connection point between the front plate 11 and the side baffle assembly 3 can be fully isolated from the oil and gas in the smoke collection chamber 12, while eliminating concerns about oil droplet contamination caused by fan rotation. This maintains the stability of the connection between the side baffle assembly 3 and the front plate 11 and the cleanliness of the connection point.
[0044] According to a further embodiment, the side of the shielding member 13 near the first connecting hole 111 is connected to the side plate 18 of the smoke collection chamber 12, so that the position of the shielding member 13 can be fixed inside the smoke collection chamber 12, stably blocking the splashing oil droplets. The shielding member 13 can be fixed by threading or welding, or, referring to the embodiment, a reinforcing plate 16 can be provided inside the side plate 18. The size of the reinforcing plate 16 is approximately the same as that of the side plate 18, and it is installed as a whole inside the smoke collection chamber 12. The side of the reinforcing plate 16 is L-shaped, and the shielding member 13 is formed by flipping down from the upper edge of the reinforcing plate 16. After the position of the reinforcing plate 16 is fixed, the shielding member 13 is naturally located above the connecting member 2.
[0045] The shield 13 has a downward-sloping surface on the side away from the first connection hole 111. Splashed oil droplets falling on the shield 13 will flow along the slope towards the center of the smoke collection chamber 12, away from the location of the first connection hole 111, and will not fall from the top of the shield 13. As a further embodiment, the lower edge of the slope is projected onto the inner side of the oil baffle 14. Oil droplets on the shield 13 will fall along the slope into the inner side of the oil baffle 14 and be blocked by the oil baffle 14, preventing them from seeping into the side of the connector 2 along the front plate 11, thus ensuring sufficient isolation of the connection position.
[0046] According to a further solution of this embodiment, such as Figure 7As shown, the side baffle assembly 3 includes a side baffle body 32 and a connecting strip 33 connected to the side baffle body 32. The side baffle body 32 is made of a thin metal material. The connecting strip 33 is arranged along the edge of the side baffle body 32. A hook 31 connected to the front plate 11 is provided on the connecting strip 33, which can expand the contact position between the hook 31 and the front plate 11, and enhance the tightness of the connection between the side baffle assembly 3 and the front plate 11 without increasing the weight of the side baffle body 32. At the same time, the connecting strip 33 is installed at the bottom of the front plate 11, so that the side baffle body 32 is located on the outer side. The outer surface of the side baffle body 32 and the outer surface of the smoke collection chamber 12 are roughly on the same plane, ensuring the flatness and aesthetics of the overall appearance of the smoke hood.
[0047] A sealing element 34 is provided on one side wall of the connecting strip 33 and the front plate 11. When the side baffle assembly 3 is connected to the front plate 11, the sealing element 34 is squeezed and connected between the connecting strip 33 and the front plate 11, sealing the connection position between the side baffle assembly 3 and the front plate 11 and increasing the tightness of the connection between the side baffle assembly 3 and the front plate 11.
[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
