Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to an oil fume extractor. Background Technology

[0002] Range hoods have become an indispensable kitchen appliance in modern homes. They operate on the principles of fluid dynamics, using a centrifugal fan inside to draw in and exhaust cooking fumes, and a filter to remove some of the grease particles.

[0003] Existing range hoods, such as the one disclosed in Chinese Patent Application No. 202320683798.9, include a smoke collection hood and a main air inlet. The smoke collection hood includes a panel support on the front side, which includes a first oil guiding part, a second oil guiding part, and a third oil guiding part from top to bottom. The main air inlet is located on the panel support. The smoke collection hood also includes a bottom plate, side plates on the left and right sides, and a rear plate between the rear sides of the two side plates. The panel support is located between the front sides of the two side plates, and the bottom plate is located between the bottom of the side plates, the rear plate, and the panel support.

[0004] The aforementioned type of range hood typically consists of three parts: the casing (smoke hood), left and right side panels, and top and rear panels. This increases production costs and installation steps, resulting in higher overall costs. A separate oil guide plate is usually located at the bottom of the casing to direct oil from the back panel to the front, flowing into the oil cup, further increasing production costs and installation steps. The oil cup is generally installed at the bottom of the casing, resulting in a significant gap between the cup and the casing when viewed from the side. Furthermore, the sides of the oil cup are usually flat, making it inconvenient to remove; one must hold the bottom and pull outwards. Additionally, the lights are typically installed in the path of the smoke intake, making them prone to grease buildup during use, which affects illumination and makes cleaning difficult over time.

[0005] Therefore, further improvements are needed. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to provide a range hood that reduces pollution from lighting devices, addressing the shortcomings of the existing technology.

[0007] The second technical problem to be solved by this utility model is to provide a range hood that reduces the production cost of the housing and the installation process, in order to address the shortcomings of the existing technology.

[0008] The first technical problem to be solved by this utility model is to provide a range hood that improves the convenience of disassembling and assembling the oil cup, in order to address the shortcomings of the existing technology.

[0009] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a range hood, comprising a housing, an oil cup, and a lighting device, wherein the housing includes a bottom plate, and a smoke inlet is provided on the front side of the housing; characterized in that:

[0011] The smoke inlet is located on the front side of the enclosure, and the lighting device is located on the rear side of the oil cup. During use, the lighting device is not in the path of the smoke intake, so it is difficult for it to get greasy, which can reduce the impact of greasy on the lighting device and make it easy to clean.

[0012] Furthermore, to facilitate the concealment of the gaps formed when the lighting device and oil cup are installed with the base plate, the housing also includes side plates, which are disposed on the left and right sides of the base plate, with the bottom of the side plates extending downward beyond the base plate.

[0013] Preferably, the bottom of the side plate is flush with the bottom of the oil cup and the lighting device, respectively.

[0014] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: the box body further includes side panels, a top panel, and a rear panel. There are two side panels arranged spaced apart from each other on the left and right. The top panel is located between the tops of the two side panels. The rear panel is located between the rear ends of the two side panels. The bottom panel is located at the bottom of the rear panel and extends forward from the bottom of the rear panel. The top panel and the rear panel are integrally formed, and the bottom panel and the side panels are fixed together. Therefore, the box body is a single unit, reducing production costs and installation steps.

[0015] To further reduce installation steps and production costs, the base plate includes a first part and a second part located in front of the first part. The first part extends downwards gradually from back to front, and the second part has an oil leakage hole, which corresponds to the top of the oil cup.

[0016] Furthermore, to facilitate the smoke inlet, a panel bracket is provided between the front ends of the side plate, top plate and bottom plate of the housing. The panel bracket has a smoke inlet. The oil cup protrudes forward from the bottom plate and the panel bracket, so that the oil cup can also collect the oil stains flowing down the panel bracket.

[0017] The technical solution adopted by this utility model to solve the third technical problem mentioned above is as follows: the oil cup includes a first cup body and a second cup body arranged front to back and in fluid communication. The left end of the first cup body extends beyond the left end of the second cup body, and the right end of the first cup body extends beyond the right end of the second cup body. Therefore, during disassembly and assembly, force can be easily applied to the oil cup by holding the protruding part of the first cup body.

[0018] To ensure good overall consistency, the left and right sides of the housing are respectively provided with a frame. The frame is located at the front of the housing. The left end of the first cup is flush with the left frame, and the right end of the first cup is flush with the right frame.

[0019] To ensure good overall consistency, the thickness of the portion of the first cup body that protrudes from the second cup body is the same as the thickness of the corresponding edge.

[0020] Furthermore, the lighting device includes a lighting module and a bracket, the lighting module being fixed to the housing via the bracket, and the lighting module being located at the bottom of the bracket.

[0021] Compared with the prior art, the advantages of this utility model are as follows: the smoke inlet is located on the front side of the box, and the lighting device is located on the rear side of the oil cup. During use, the lighting device is not in the path of oil fume intake, so it is difficult to get oil stains, which can reduce the impact of oil stains on the lighting device and facilitate cleaning; the side panel of the box covers the gap between the lighting device and the oil cup installation, which can improve the consistency of the whole machine; the box is a whole, which reduces production costs and installation steps; the oil cup is designed in a "T" shape, which improves the integrity and aesthetics of the whole machine. At the same time, when the user disassembles and installs the oil cup, he / she can hold the thinner part of the oil cup at the bottom of the side frame with both hands and pull it forward, which improves the convenience of disassembling and installing the oil cup.

[0029] See Figures 1-5 A range hood includes a housing 1, a frame 2, a fan system 3, a panel bracket 4, an oil cup 5, and a lighting device 6.

[0030] The housing 1 includes side plates 11, a top plate 12, a rear plate 13, and a bottom plate 14. There are two side plates 11, spaced apart on the left and right. The top plate 12 is located between the tops of the two side plates 11, and the rear plate 13 is located between the rear ends of the two side plates 11. The top plate 12 and the rear plate 13 can be integrally formed. The bottom plate 14 is located at the bottom of the rear plate 13 and extends forward from the bottom of the rear plate 13. The bottom plate 14 includes a first part 141 and a second part 142 arranged front to back. The first part 141 is configured as an oil guide plate, gradually sloping downwards from back to front. The second part 142 has an oil leakage hole 143 and can be approximately horizontal. Preferably, the first part 141 can form an angle greater than 10° with the horizontal plane. The left and right sides of the bottom plate 14 can be welded and fixed to the corresponding side plates 11 to ensure sealing. The rear plate 13 and the bottom plate 14 can be integrally formed. Thus, the aforementioned box 1 forms a whole, reducing production and assembly processes and lowering costs.

[0031] The fan system 3 is installed inside the housing 1. The panel bracket 4 mentioned above is provided between the front ends of the side plate 11, top plate 12 and bottom plate 14. The panel bracket 4 has a smoke inlet 41 and a filter screen 42 is provided at the smoke inlet 41. The air inlet of the fan system 3 faces the smoke inlet 41. The oil fumes enter the housing 1 through the smoke inlet 41 and are discharged after passing through the fan system 3.

[0032] Oil stains flowing down the inner wall of the housing 1 and the fan system 3 reach the bottom plate 14, then flow along the first part 141 to the second part 142, and through the oil drain hole 143 on the second part 142 into the oil cup 5 located below the second part 142. Thus, the oil cup 5 is located at the front bottom of the housing 1 and protrudes forward from the bottom plate 14 and the panel support 4, ensuring that the oil on the panel support 4 can flow smoothly into the oil cup 5.

[0033] The aforementioned frame 2 is provided on the left and right sides of the housing 1, and the frame 2 is located on the front side of the housing 1, corresponding to the panel bracket 4. Therefore, the oil cup 5 has a T-shaped cross-section. The oil cup 5 includes a first cup body 51 and a second cup body 52 arranged front to back. Figure 5 (The boundary line between the two cups is represented by a dashed line L). The two cups are fluidly connected, and in this embodiment, the junction of the two cups is open. The length of the first cup 51 in the left-right direction is the same as the length of the second cup 52 in the left-right direction, that is, the left end of the first cup 51 extends beyond the left end of the second cup 52, and the right end of the first cup 51 extends beyond the right end of the second cup 52. The left end of the first cup 51 is flush with the left side frame 2, and the right end of the first cup 51 is flush with the right side frame 2, that is, the left and right sides do not protrude from the frame 2 and are located below the frame 2. The thickness (front-back dimension) of the part of the first cup 51 that protrudes from the second cup 52 is the same as the thickness of the corresponding frame 2, thereby improving the integrity and aesthetics of the whole machine. At the same time, when the user disassembles and assembles the oil cup 5, they can hold the thinner part of the oil cup 5 at the bottom of the two side frames 2 with both hands and pull it forward, improving the convenience of disassembling and assembling the oil cup 5.

[0034] The lighting device 6 is located at the bottom of the housing 1, behind the oil cup 5. The lighting device 6 includes a lighting module 61 and a bracket 62. The lighting module 61 is fixed to the housing 1 via the bracket 62. The lighting module 61 can be located at the bottom of the bracket 62, but more preferably at the center in the front-to-back direction. It is configured with a polarizer or similar device to polarize the light downwards and forwards during use, ensuring the center of the illumination corresponds to the center of the stove. The bottom of the bracket 62 and the bottom of the oil cup 5 are preferably flush.

[0035] The bottom of the side panel 11 of the housing 1 extends below the bottom plate 14 and is flush with the bottom of the bracket 62 and the oil cup 5. This effectively conceals the gaps between the bracket 62, the oil cup 5 and the housing 1, improving the overall integrity and aesthetics of the machine.

[0036] The range hood may also include a baffle plate 7 that can open and close the smoke inlet 41, and its movement mechanism may be existing, such as driving the baffle plate 7 to flip or move linearly.

[0037] The term "fluid connectivity" as used in this utility model refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
