Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to a side plate sealing structure and a range hood. Background Technology

[0002] A range hood, also known as a cooking hood, is a kitchen appliance used 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 air collection box and the baffle housing are connected by a top plate. The top plate has a smoke collection chamber connected to the air collection box, used to collect condensed fumes that do not exit the air collection box. The baffle housing is usually formed by a top plate and side baffle assemblies on both sides of the top plate. Connection holes are provided on both sides of the top plate, and hooks that engage with these connection holes are located on the inner side of the side baffle assemblies. Since the first connecting hole is connected to the smoke collection chamber, the smoke in the smoke collection chamber will accumulate on the top plate. After long-term use of the range hood, the accumulated oil will flow out from the gap between the connecting hole and the hook and flow through the smoke side baffle, causing pollution to the side baffle assembly and affecting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a side plate sealing structure to solve the above-mentioned technical problems.

[0004] This utility model proposes a side plate sealing structure for connecting the side baffle assembly of a range hood, comprising:

[0005] The main body of the range hood includes a top plate connected to the lower part of the air collection box, and the top plate has first connecting holes on both sides;

[0006] A sealing connector is attached to the top plate of the main body of the range hood and covers the first connecting hole. The sealing connector has a connecting cavity and a second connecting hole. The second connecting hole is on the bottom plate of the connecting cavity and communicates with the connecting cavity. The second connecting hole is corresponding to the first connecting hole.

[0007] According to one embodiment of the present invention, the front-to-back dimension of the second connecting hole is smaller than the front-to-back dimension of the connecting cavity, and the bottom plate of the connecting cavity is used to support the hook of the side baffle assembly of the range hood.

[0008] According to one embodiment of the present invention, the sealing connector includes a connecting seat and a sealing plate. The connecting seat is connected to the upper surface of the top plate of the main body of the smoke hood. The connecting seat is provided with a connecting cavity and a second connecting hole. The second connecting hole is located on the bottom surface of the connecting seat. The upper surface of the connecting seat is also provided with a mold hole communicating with the connecting cavity. The sealing plate is connected to the upper surface of the connecting seat and covers the mold hole.

[0009] According to one embodiment of the present invention, the ejector hole and the second connecting hole are staggered. The second connecting hole is located on one side of the bottom surface of the connecting seat and extends from one side of the bottom plate of the connecting seat to the other side. The ejector hole is located on the other side of the upper surface of the connecting seat and extends from the other side of the upper surface of the connecting seat to one side. The portion of the bottom plate of the connecting cavity that aligns with the ejector hole is smaller than the size of the ejector hole. The portion of the top plate of the connecting cavity that aligns with the second connecting hole is smaller than the size of the second connecting hole.

[0010] According to one embodiment of the present invention, the bottom plate of the connecting cavity is provided with a protruding rib, which squeezes the hook when the hook of the side baffle assembly of the smoke machine is engaged in the connecting cavity.

[0011] According to one embodiment of the present invention, the upper surface of the connecting seat is provided with a positioning protrusion, and the sealing plate is provided with a positioning hole corresponding to the positioning protrusion, and the positioning protrusion is connected to the positioning hole.

[0012] According to one embodiment of the present invention, the bottom sides of the connecting seat are further provided with extension edges, which extend from the bottom plate of the connecting cavity to the outer side and connect with the top plate.

[0013] According to one embodiment of the present invention, a third connecting hole is provided on the extension side, and a fourth connecting hole is provided on the top plate. The connecting seat is connected to the top plate through the fourth connecting hole and the third connecting hole.

[0014] According to one embodiment of the present invention, an upwardly extending connecting post is provided on the extension side, and a third connecting hole extends upward from the bottom along the connecting post; the fourth connecting hole is a countersinking hole.

[0015] This utility model also proposes a range hood that adopts the above-mentioned sealing side plate sealing structure, including a range hood body and a side baffle assembly. The side baffle assembly is provided with a hook, which passes through the first connecting hole and the second connecting hole in sequence and is connected to the connecting cavity.

[0016] Compared with existing technologies, the side panel sealing structure disclosed in this utility model features a sealing connector on the top plate of a conventional range hood. This sealing connector covers the surface of the first connecting hole, and a second connecting hole and a connecting cavity communicating with the second connecting hole are provided at the corresponding positions. When the side baffle assembly is connected to the main body of the range hood, the hooks on the side baffle assembly are sequentially passed through the first and second connecting holes and engaged in the connecting cavity, thereby stabilizing the position of the side baffle assembly. Because the upper part of the first connecting hole is covered by the sealing connector, during long-term use, the oil in the smoke collection chamber will not flow out through the gap between the first connecting hole and the hook, ensuring the aesthetic appearance of the range hood side baffle assembly and improving the user experience.

[0017] The embodiment specifically provides a structure for the sealing connector. The sealing connector is divided into upper and lower parts through a split design of the sealing plate and the connecting seat. The connecting cavity is located within the connecting seat. The upper and lower surfaces of the connecting seat are respectively provided with a second connecting hole and a demolding hole communicating with the connecting cavity. Demolding from the upper and lower surfaces of the connecting seat facilitates the formation of the snap-fit ​​structure within the connecting cavity. The sealing plate is then placed over the surface of the demolding hole, thus isolating the interior of the connecting cavity from the smoke collection cavity from above. The lower surface of the connecting seat also has an extension edge that abuts against the top plate, fixing the position of the sealing connector while isolating the lower part of the connecting cavity from the smoke collection cavity.

[0029] 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:

[0030] This utility model discloses a side plate 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 shielding shell. A fan is installed in the air collection box to provide the power required for the flow of smoke from the range hood. When the fan is started, it will form a circulating airflow at the bottom of the air collection box. The shielding shell is connected to the lower part of the air collection box and communicates with the air collection box. It includes two side baffle assemblies 3 to guide the flow of kitchen smoke. The smoke enters from the user side of the range hood and enters the smoke collection chamber from below after being blocked by the side baffle assemblies 3.

[0031] With the user side as the front of the range hood and the side facing away from the user side as the rear, the shielding housing includes a top plate 13 connected to the lower part of the air collection box. The top plate 13 has a smoke collection chamber area that connects to the air collection box, where some of the smoke flowing within the air collection box will remain. First connecting holes 11 are provided on the left and right sides of the top plate 13. The side baffle assembly 3 has hooks 31 extending into the first connecting holes 11, respectively engaging with the two side baffle assemblies 3 of the shielding housing. The two side baffles are located on the left and right sides of the top plate 13, forming an air guiding area with the top plate 13. The engaging principle of the hooks 31 and the first connecting holes 11 is that the hooks 31 extend into the first connecting holes 11 and engage with the bottom plate to complete the installation of the side baffle assembly 3. This engaging structure is existing technology, and the specific structure of the hooks 31 will not be described here. The top plate 13 serves as the connecting component between the upper air collecting box and the lower side baffle assembly 3. After prolonged use, some of the smoke from the smoke collecting chamber will accumulate oil inside the top plate 13. When the hook 31 is connected to the top plate 13, it needs to be inserted into the first connecting hole 11. The oil accumulated on the top plate 13 will seep out from the first connecting hole 11, affecting both the appearance of the range hood and the user experience. The purpose of this utility model is to provide a side plate assembly connection solution that can reduce the leakage of oil from the smoke collecting chamber through the first connecting hole 11.

[0032] Specifically, each of the first connecting holes 11 in the smoke collection chamber is provided with a... Figure 3 and Figure 4 The sealing connector 2 shown is generally a shell structure, containing a hollow connecting cavity 211. A shield is attached above the first connecting hole 11, isolating the first connecting hole 11 from the upper smoke collection chamber. Because the top of the first connecting hole 11 is covered, the oil and gas in the smoke collection chamber will not leak from the first connecting hole 11. The middle part of the sealing connector 2 is a hollow connecting cavity 211, used to accommodate the hook 31 of the side baffle assembly 3. The bottom of the connecting cavity 211 has a second connecting hole 212, which communicates with the connecting cavity 211 and corresponds to the first connecting hole 11. The hook 31 of the side baffle assembly 3 can pass through the first connecting hole 11 and the second connecting hole 212 in sequence and engage in the connecting cavity 211 to fix the position of the side baffle.

[0033] To form the hollow connecting cavity 211, the sealing connector 2 includes side edges 2110 on both sides of the connecting cavity 211, a top edge 219 at the top of the connecting cavity 211, and a bottom plate 2111 at the bottom of the connecting cavity 211. The sealing connector 2 is formed by injection molding. For the forming process of the second connecting hole 212, the shape of the entire bottom plate 2111 of the connecting cavity 211 can be machined first, and then the second connecting hole 212 can be directly formed on the bottom plate 2111 of the connecting cavity 211. Then, the second connecting hole 212 and the first connecting hole 11 are aligned. Alternatively, refer to... Figure 3In this method, during the molding stage, the bottom plate 2111 of the connecting cavity 211 is formed by bending the bottom of the side 2110 of the connecting cavity 211 inwards through integral molding. The bottom plate 2111 can be bent inwards from one side 2110 or extended inwards from both sides 2110 simultaneously, thereby forming a notch between the side 2110 of the connecting cavity 211 and the bottom plate 2111, or between the bottom plates 2111 bent from both sides 2110. This notch serves as the second connecting hole 212 connecting the connecting cavity 211 and the first connecting hole 11. This method of preparing the sealing connector 2 and the second connecting hole 212 has the advantages of simplicity and convenience, and it is easy to form the required structure within the connecting cavity 211.

[0034] The front-to-back dimension of the second connecting hole 212 is further set to be smaller than the front-to-back dimension of the connecting cavity 211. After the hook 31 extends into the second connecting hole 212, a snap-fit ​​structure supporting the hook 31 can be provided on the bottom plate 2111 of the connecting cavity 211. For example, in this embodiment, a protruding rib 214 protruding from the surface of the bottom plate 2111 is provided on the bottom plate 2111 of the connecting cavity 211. After assembling the side baffle assembly 3, the hook 31 is pressed against the inner side of the protruding rib 214. The protruding rib 214 can provide a certain resistance to the movement of the hook 31, stabilize the position of the side baffle assembly 3, and prevent the connection between the side baffle assembly 3 and the top plate 13 from loosening due to insufficient external force. It should be noted that the snap-fit ​​structure for fixing the hook 31 is not limited to the above-mentioned protruding rib 214. Some common snap-fit ​​structures can be used, such as a groove or a collar in the connecting cavity 211. The head of the hook 31 can be snapped into the groove or the collar to fix the hook 31 inside the connecting cavity 211. Meanwhile, the aforementioned snap-fit ​​structure of the hook 31 is not strictly limited to the bottom plate 2111 of the connecting cavity 211, but can be connected to the side 2110 or even the top edge 219 of the connecting cavity 211.

[0035] The second connecting hole 212 is located at the bottom of the connecting cavity 211. When the entire sealing connector 2 is an integral injection molded structure, the upper surface of the sealing connector 2 is sealed, making it difficult to demold from the second connecting hole 212 after molding, especially when the size of the connecting cavity 211 is larger than the second connecting hole 212. It is also difficult to machine the internal shape of the connecting cavity 211 using the molded core. To further facilitate the molding of the sealing connector 2, the sealing connector 2 is configured as follows... Figure 4The diagram shows two parts: a connecting seat 21 and a sealing plate 22. The connecting seat 21 is located below the top plate 13 and is connected to the upper surface of the top plate 13. A connecting cavity 211 and a second connecting hole 212 are provided on the connecting seat 21. A mold hole 213 is provided on the top edge 219 of the connecting seat 21, and the mold hole 213 communicates with the connecting cavity 211. Each of the mold hole 213 and the second connecting hole 212 has a core that participates in the molding of the connecting cavity 211. After molding, part of the cavity is ejected from the bottom through the second connecting hole 212, and part is ejected from the top through the mold hole 213, thereby achieving rapid molding and ejection of the connecting cavity 211. The sealing plate 22 is connected to the upper surface of the connecting seat 21 and covers the mold hole 213. After the connecting cavity 211 is molded, the sealing plate 22 isolates the connecting cavity 211 from the upper smoke collection chamber, achieving a seal on the upper space of the connecting cavity 211, preventing oil and gas from entering the connecting cavity 211 through the mold hole 213.

[0036] In the side plate sealing structure of this utility model, the second connecting hole 212 is located on one side of the bottom plate 2111 of the connecting cavity 211, and the ejection hole 213 is located on the other side of the top edge 219 of the connecting cavity 211. The dimensions of the ejection hole 213 and the second connecting hole 212 are smaller than the width dimension of the connecting cavity 211, so that the ejection hole 213 and the second connecting hole 212 are staggered in the front-back direction. The cores of the upper and lower parts are ejected from the two sides of the connecting cavity 211 respectively. The ejection process does not interfere with each other and simplifies the ejection process of the core.

[0037] The sealing plate 22 can be sized to only cover the mold outlet 213, and can be snapped into the mold outlet by pressing. Alternatively, a method such as... Figure 4 The fixing method shown involves setting the sealing plate 22 as a plate-like structure, covering the upper surface of the mold hole 213 and the connecting seat 21, thereby increasing the coverage area of ​​the sealing plate 22 and reducing the probability of oil and gas seeping into the mold hole 213. The upper surface of the connecting seat 21 is provided with a positioning protrusion 215, and the sealing plate 22 is provided with a positioning hole 221 corresponding to the position of the positioning protrusion 215. The positioning protrusion 215 is fitted into the positioning hole 221, which can quickly position the installation position of the sealing plate 22 and achieve sealing of the mold hole 213.

[0038] The side-plate sealing structure of this utility model has extension edges 216 on both sides of the bottom of the connecting seat 21. The extension edges 216 extend from the bottom plate 2111 of the connecting cavity 211 to the outer side 2110. The extension edges 216 are used to connect with the top plate 13 of the shielding shell. The connecting seat 21 is fixed to the upper surface of the top plate 13 by external connectors. The extension edges 216 are located on both sides of the connecting cavity 211, which can avoid the snap-fit ​​position of the hook 31 in the connecting cavity 211 and reduce interference with the connection of the hook 31. At the same time, the fixed extension edges 216 support the connecting cavity 211 from both sides, increasing the connection stability of the middle connecting cavity 211. The extension edge 216 and the top plate 13 can be fixed by conventional connection methods such as threaded connection, riveting, snap-fit, and sleeve connection. In this embodiment, a set of third connecting holes 217 are provided on each extension edge 216, and a fourth connecting hole 12 is provided on the top plate 13 corresponding to the position of each set of third connecting holes 217. Connectors are installed at the third connecting holes 217 and the fourth connecting holes 12. The connector passes through the third connecting holes 217 and the fourth connecting holes 12 in sequence, so that the connecting seat 21 can be fixed above the top plate 13.

[0039] The side plate sealing structure of this utility model uses a threaded connector to connect the extension edge 216 and the top plate 13. Each extension edge 216 has an upwardly extending connecting post 218, and a third connecting hole 217 extends upwards along the connecting post 218 from the bottom. The threaded connector passes through a fourth connecting hole 12 and extends into the third connecting hole 217 of the connecting post 218. The connecting post 218 can position and guide the connection position of the threaded connector, strengthening the stable connection between the connecting seat 21 and the top plate 13. The fourth connecting hole 12 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 top plate 13 and preventing the threaded connector from being exposed and damaged by accidental contact during use.

[0040] Figure 5 A range hood including the aforementioned sealing connector 2 was demonstrated, in conjunction with which... Figure 6The assembly process of the smoke hood is described as follows: A fan is installed inside the air collection box. A sealing connector 2 is installed on the upper surface of the top plate 13, aligning the second connecting hole 212 of the sealing connector 2 with the first connecting hole 11 on the top plate 13, and aligning the third connecting hole 217 of the sealing connector 2 with the fourth connecting hole 12 on the top plate 13. A threaded connector is screwed in below the fourth connecting hole 12, fixing the sealing connector 2 above the top plate 13. A sealing plate 22 is then installed at the bottom of the connecting seat 21, engaging with the positioning protrusion 215 on the top plate 13 and covering the surface of the die hole 213. This completes the connection between the sealing connector 2 and the top plate 13. The top plate 13 is then installed at the bottom of the air collection box. Side baffle assemblies 3 are installed on the left and right sides of the top plate 13, with the hooks 31 on the side baffle assemblies 3 passing through the first connecting hole 11 and the second connecting hole 212, engaging within the connecting cavity 211.

[0041] 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.
