Description

Technical Field

[0001] This application relates to a range hood. Background Technology

[0002] In the prior art, the smoke collection hood and the oil filter of the range hood are located at the bottom of the fan frame and are two separate components. They are assembled separately on the assembly line after sheet metal forming and spraying processes. That is, the fan frame is first installed on the smoke collection hood by passing through it and then screws are used to install it on the smoke collection hood. Then the oil filter is also installed on the smoke collection hood by screws.

[0003] However, this assembly method has several shortcomings: First, the fan frame is directly connected to the air inlet area of ​​the fume hood. The structural dimensions of the air inlet area directly limit the structural dimensions of the fan frame; otherwise, it would be impossible to install the fan frame through the fume hood to achieve the connection between the two. Second, since the fan frame needs to pass through the fume hood, a folded edge is provided in the central area of ​​the fume hood for the connection of the fan frame. This means that the fan frame acts directly on the fume hood, which leads to damage due to direct stress on the fume hood and significant vibration of the fume hood during use. Third, the grease filter is connected to the fume hood with screws. Disassembly and cleaning by users affects the user experience. If it is not disassembled, the grease in the gap between the grease filter and the fume hood is difficult to clean. Finally, the two parts are formed, painted, and assembled separately, which increases the investment in equipment, materials, and labor.

[0004] Therefore, the above-mentioned problems urgently need to be addressed. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this application is to solve the problem that the weight of the fan assembly and the vibration generated during operation no longer directly act on the smoke hood body, avoid damage to the smoke hood body caused by long-term concentrated force, improve the flexibility and applicability of the smoke hood assembly connection, so that it can be equipped with fan assemblies of different specifications and sizes, and improve the ease of cleaning the smoke hood.

[0006] To address the aforementioned problems, this application provides a range hood, comprising a fan assembly and a smoke collection hood assembly disposed at the bottom of the fan assembly. The smoke collection hood assembly includes a smoke collection hood body and a connector. An oil mesh is provided on the smoke collection hood body. Along the direction of smoke flow, the oil mesh and the smoke collection hood body are disposed on the same plane. The oil mesh forms an air inlet for smoke flow. The air inlet is connected to the air inlet channel of the fan assembly. The connector is disposed on the side surface of the smoke collection hood body facing the fan assembly for connection with the fan assembly.

[0007] Preferably, both the oil screen and the fan assembly are located on the central axis of the fume hood body, and along the direction of oil fume flow, the cross-sectional dimension of the air inlet channel of the fan assembly is not less than the cross-sectional dimension of the oil screen.

[0008] Preferably, there are multiple connectors, each of which is disposed around the periphery of the oil mesh and extends along the extension direction of the oil mesh, such that the multiple connectors surround each other to form the air inlet.

[0009] Preferably, the connector is a bent sheet structure, with one end connected to the surface of the smoke hood body and the other end extending toward one side of the fan assembly to be connected to the fan assembly.

[0010] Preferably, the smoke hood body is provided with opposing positioning protrusions, and the opposing positioning protrusions form an area for placing the connector to position the connector. The connector is provided with positioning grooves that are adapted to the positioning protrusions at both ends corresponding to the positioning protrusions.

[0011] Preferably, the oil mesh and the smoke collection hood body are smoothly connected.

[0012] Preferably, a smoke collection chamber is provided on the side of the smoke collection hood body away from the fan assembly, the smoke collection chamber protrudes towards the fan assembly and is located on at least one side of the oil screen.

[0013] Preferably, the range hood further includes a cover plate, which is disposed on the outer periphery of the fan assembly and surrounds the fan assembly. A folded edge extending toward the fan assembly is provided at the outer edge of the smoke collection hood body for connection with the cover plate.

[0014] Preferably, the connector is fixedly mounted on the smoke hood body by welding, and the connector has a connection hole for movably connecting with the fan assembly.

[0015] Preferably, the smoke hood body is manufactured using a stamping process.

[0016] Due to the above technical solution, the range hood described in this application has the following beneficial effects:

[0017] By employing additional connectors to link the fume hood body and the fan assembly, the weight and vibrations generated by the fan assembly during operation are no longer directly applied to the fume hood body. Instead, they first act on the connectors and then are transmitted to the fume hood body. This extended vibration transmission path prevents damage to the fume hood body caused by prolonged concentrated forces. Furthermore, the connector design can be optimized to accommodate different models and specifications of fan assemblies, increasing the flexibility and applicability of the fume hood assembly connection. In addition, placing the oil filter and the fume hood body on the same plane reduces complex corners and hard-to-reach areas during cleaning, making the cleaning and maintenance of the fume hood assembly more convenient.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0029] like Figures 1-7 As shown, this application provides a range hood 100, which includes a fan assembly 200 and a smoke collection hood assembly 300 disposed at the bottom of the fan assembly 200. The smoke collection hood assembly 300 includes a smoke collection hood body 31 and a connector 32. An oil mesh 33 is provided on the smoke collection hood body 31. Along the direction of smoke flow, the oil mesh 33 and the smoke collection hood body 31 are disposed on the same plane. The oil mesh 33 forms an air inlet 34 for smoke flow. The air inlet 34 is connected to the air inlet channel of the fan assembly 200. The connector 32 is disposed on the side surface of the smoke collection hood body 31 facing the fan assembly 200 for connection with the fan assembly 200.

[0030] By employing an additional connector 32 to connect the smoke hood body 31 and the fan assembly 200, the weight and vibrations generated by the fan assembly 200 during operation no longer act directly on the smoke hood body 31. Instead, they first act on the connector 32 and then are transmitted to the smoke hood body 31. This extended vibration transmission path prevents damage to the smoke hood body 31 caused by prolonged concentrated force. Furthermore, the design of the connector 32 can be optimized according to actual needs to accommodate different models and specifications of fan assemblies 200, increasing the flexibility and applicability of the smoke hood assembly 300 connection. In addition, placing the oil screen 33 and the smoke hood body 31 on the same plane reduces complex corners and hard-to-reach areas during cleaning, making the cleaning and maintenance of the smoke hood assembly 300 more convenient.

[0031] like Figures 2-3 As shown, the oil mesh 33 and the smoke hood body 31 are smoothly connected. This design not only reduces the number of complicated corners and hard-to-reach areas during cleaning, making cleaning and maintenance more convenient, but also enhances the structural strength between the oil mesh 33 and the smoke hood body 31. At the same time, when it is necessary to replace the fan frame 21 with a different size, there is no need to adjust the size of the oil mesh 33 or the density of the through holes 331 on the oil mesh 33. The connection between the fan frame 21 and the smoke hood body 31 can be achieved simply by adjusting the position of the connector 32.

[0032] Specifically, the oil mesh 33 is provided with a number of through holes 331 for the flow of oil fumes. The through holes 331 are in the shape of regular hexagons. The number of through holes 331 are arranged in an array on the smoke collection hood body 31 to form the air inlet 34.

[0033] like Figure 1 As shown, the oil mesh 33 and the fan assembly 200 are both located on the central axis of the fume hood body 31. Along the direction of oil fume flow, the cross-sectional dimension of the air inlet channel of the fan assembly 200 is not smaller than the cross-sectional dimension of the oil mesh 33. This arrangement ensures that the fan assembly 200 can completely cover the air inlet 34, thereby effectively drawing in oil fumes under negative pressure, preventing oil fumes from overflowing from the edge of the air inlet 34, and improving the oil fume extraction efficiency of the range hood 100.

[0034] like Figures 2-3As shown, there are multiple connectors 32, all arranged around the periphery of the oil mesh 33. This enhances the stability of the connection between the smoke hood body 31 and the fan assembly 200, reducing the risk of loosening due to long-term use or vibration. Furthermore, the evenly distributed connectors 32 help disperse stress on the smoke hood body 31, reducing potential safety hazards caused by excessive force on a single connection point. Simultaneously, the multiple connectors 32 extend along the extension direction of the oil mesh 33, forming an air inlet 34. This ensures more precise alignment between the oil mesh 33 and the fan assembly 200, improving the assembly quality of the fan assembly 200 and the smoke hood assembly 300.

[0035] In this embodiment, there are three connectors 32. The three connectors 32 are arranged alternately on the three sides of the oil mesh 33. The purpose of not having a connector 32 on the remaining side is that this side is used to install the fan side plate (not shown in the figure), so there is no need to install an additional connector 32. Furthermore, the three connectors 32 extend along the length and width directions of the oil mesh 33, respectively, to maximize the contact area with the fan assembly 200, thereby enhancing the stability of the connection between the connectors 32 and the fan frame 21 in the fan assembly 200.

[0036] like Figures 5-6 As shown, the smoke hood body 31 is also provided with a positioning protrusion 35 that is arranged opposite to each other. The positioning protrusion 35 forms an area for the connector 32 to be placed to position the connector 32. The connector 32 is provided with positioning grooves 321 that are adapted to the positioning protrusion 35 at both ends corresponding to the positioning protrusion 35.

[0037] The design of the positioning protrusion 35 and the positioning groove 321 ensures the precise position of the connector 32 on the smoke hood body 31, avoiding deviations during installation and guaranteeing proper alignment between the fan assembly 200 and the smoke hood body 31. Furthermore, the cooperation of the positioning protrusion 35 and the positioning groove 321 simplifies the assembly process of the connector 32, thereby reducing the time required for adjustment and calibration when connecting the fan frame 21 and the smoke hood body 31.

[0038] In this embodiment, six positioning protrusions 35 are provided on the side of the smoke hood body 31 facing the fan assembly 200, which are used to position the three connectors 32. The positioning protrusions 35 are also correspondingly arranged at both ends of the connectors 32 along the length and width directions of the oil mesh 33 to achieve their positioning function. Furthermore, the positioning groove 321 is a semi-circular groove structure to fit the positioning protrusions 35. Therefore, when connecting the connectors 32 to the smoke hood body 31, the positioning grooves 321 of the connectors 32 are first placed against the positioning protrusions 35 of the smoke hood body 31, and then other connection processes are used to achieve the connection between the two.

[0039] like Figures 5-6 As shown, the connector 32 is a bent sheet structure. Specifically, one end of the connector 32 is connected to the surface of the smoke hood body 31, and the other end extends toward one side of the fan assembly 200 so as to be connected to the fan assembly 200.

[0040] The bent sheet structure not only provides a larger contact area and better mechanical properties, thus enhancing the stability and tensile strength of the connector 32 and making the connection between the smoke hood body 31 and the fan assembly 200 more robust, but also better withstands the long-term vibration of the fan assembly 200, thereby improving the service life of the connector 32 and the overall durability of the range hood 100. Furthermore, the bent connector 32 fits more closely to the smoke hood body 31 and the fan frame 21, making the design of the range hood 100 more compact and aesthetically pleasing.

[0041] In other embodiments, the structure of the connector 32 can be configured as needed to meet its connection requirements with the fan frame 21.

[0042] Furthermore, in this embodiment, the connector 32 is fixedly mounted on the smoke hood body 31 by welding to ensure sufficient structural stability between the connector 32 and the smoke hood body 31. This makes the operation of the entire range hood 100 more reliable, and the connector 32 remains fixed even under continuous operation or vibration conditions, preventing it from easily falling off. Additionally, the connector 32 is provided with a connection hole 322 for movable connection with the fan frame 21, facilitating operation during installation and simplifying the process.

[0043] In this embodiment, there are multiple connecting holes 322, which are arranged at intervals along the extending direction of the connector 32. Specifically, the connecting holes 322 are rivet holes, corresponding one-to-one with the holes at the bottom of the fan frame 21. Furthermore, to facilitate the riveting of the fan assembly 200 and the smoke hood assembly 300, please refer to the attached diagram for details. Figure 7 The placement of the two items.

[0044] like Figure 4 As shown, a smoke collection chamber 36 is provided on the side of the smoke collection hood body 31 away from the fan assembly 200. The smoke collection chamber 36 protrudes towards the fan assembly 200 and is located on at least one side of the oil mesh 33. Preferably, the smoke collection chamber 36 is provided at both ends of the oil mesh 33 along its length to guide and concentrate the oil fumes, so that the oil fumes can be more effectively drawn into the oil mesh 33 and into the fan assembly 200, reducing the diffusion of oil fumes in the kitchen and thus improving the smoke collection effect of the range hood 100.

[0045] like Figures 2-4 As shown, the range hood 100 also includes a cover plate (not shown in the figure). The cover plate is disposed on the side of the smoke collection hood body 31 facing the fan assembly 200 and is located on the outer periphery of the fan assembly 200 to surround the fan assembly 200. Furthermore, a flange 37 extending towards the fan assembly 200 is provided at the outer edge of the smoke collection hood body 31 for connection with the cover plate. In this embodiment, the cover plate is used to close the smoke collection chamber 36 to prevent the oil fumes from overflowing, so as to ensure that the oil fumes are effectively drawn in and discharged.

[0046] Furthermore, the smoke hood body 31 in this embodiment is manufactured using a stamping process and formed using sheet metal molds. Since the smoke hood body 31 and the oil mesh 33 are designed as a single integral structure, they are suitable for stamping processing. Stamping is suitable for mass production, enabling the rapid and continuous manufacture of a large number of smoke hood bodies 31 with uniform shapes, thus improving production efficiency. Moreover, the stamping process can precisely control the shape and size of the material, ensuring the dimensional accuracy and surface quality of the smoke hood body 31, meeting assembly and functional requirements.

[0047] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
