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] Existing range hoods with fixed air inlets typically have a protective mesh installed at the air inlet to comply with safety regulations, and a bottom reinforcing plate is installed at the bottom of the casing to enhance its strength. Both the protective mesh and the bottom reinforcing plate are independent components. The lower glass panel assembly is clipped onto the protective mesh. Because the lower glass panel assembly and the protective mesh are independent, gaps exist between the two components. Condensed oil from the upper part flows along these gaps to the inside of the lower glass panel, forming a "water curtain" as it falls, resulting in a poor user experience. To avoid this, an oil guide strip is often installed on the inside of the lower glass panel to guide the condensed oil to the sides of the casing, preventing the "water curtain" from forming. This structure with an oil guide strip results in a large number of components, numerous processing and assembly steps, low material utilization, and high material and manufacturing costs. Furthermore, the lower glass panel assembly suffers from poor overall rigidity due to its large size and relatively small support surface for the clips and oil guide strips. Additionally, the thin strips on both sides of the lower end lack back sheet metal support, making it difficult to ensure uniformity of the gap between the lower glass panel and the side panels of the enclosure. The thin strips on both sides are particularly prone to warping. Moreover, because the upper part of the lower glass panel is only connected by clips, the clips are designed with weak rigidity to ensure smooth installation. This can lead to significant lateral steps between the upper side of the lower glass panel and the left and right side panels of the enclosure during drop tests, causing the test to fail. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a range hood that can simplify the materials of the lower panel support and ensure the overall rigidity of the lower panel assembly, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a range hood, including an upper box and a lower box located below the upper box, a lower panel is provided on the front side of the lower box, a lower panel bracket is installed inside the lower box, the lower panel bracket is located on the back side of the lower panel, and the lower panel is fixed on the lower panel bracket, characterized in that: the lower panel bracket includes a front side plate, the lower edge of the front side plate is bent backward to form a protective net, the rear edge of the protective net is bent forward and downward to form a guide plate, and bracket side plates are provided on the left and right sides of the protective net and the guide plate, the protective net, the guide plate and the bracket side plates form the air inlet of the lower box, and the bracket side plates are fixed on the corresponding side wall of the lower box.

[0005] To reduce the turning angle of the fume path, making the fume intake path smoother and more unobstructed, thereby reducing noise and improving fume extraction efficiency, the protective net extends diagonally downwards from front to back. The rear edge of the protective net is first bent vertically downwards to form a vertical bend, and the lower edge of the vertical bend is bent forward and downwards to form the guide plate. In addition, the vertical bend also helps to improve the structural strength of the lower panel support.

[0006] In order to allow the oil fumes inside the range hood to flow smoothly into the oil cup, an oil cup is installed at the bottom of the lower housing. The vertical projection of the lower edge of the guide plate falls into the oil cup, and the vertical projection of the vertical bend falls into the oil cup.

[0007] In order to improve the structural strength of the guide plate and fix the guide plate to the lower housing, the lower edge of the guide plate is bent to form a bottom edge, and the bottom edge is fixed to the bottom of the lower housing.

[0008] In order to bond and fix the lower panel to the lower panel bracket, the front edge of the bracket side panel is bent outward to form an outer folded edge of the side panel. The front side of the front side panel forms a first bonding surface, and the front side of the outer folded edge of the side panel forms a second bonding surface. Both the first bonding surface and the second bonding surface are bonded and fixed to the back of the lower panel.

[0009] In order to fix the lower panel bracket to the lower housing, the bracket side plate has mounting holes, and the bracket side plate is fixed to the corresponding side wall of the lower housing through the mounting holes.

[0010] To further secure the lower panel bracket to the lower housing, a first buckle is provided on the front side panel, and a second buckle is provided on the outer folded edge of the side panel. The lower panel bracket is secured to the corresponding side wall of the lower housing by the first and second buckles.

[0011] To make the structure between the support side plate, the protective net, and the guide plate more robust, the upper edge of the support side plate is bent inward to form an upper folded edge, and the lower edge of the support side plate is bent inward to form a lower folded edge. The upper folded edge of the side plate is fixed to the protective net, and the lower folded edge of the side plate is fixed to the guide plate.

[0012] To further secure the lower panel bracket to the lower housing, a mounting bracket is formed on the back of the front panel, and there are at least two mounting brackets spaced apart on the left and right.

[0013] In order to increase the air intake area and reduce the air intake resistance, the mounting bracket has grille holes.

[0014] To limit the installation of the oil filter screen, the upper edge of the front side plate is bent backward to form a front side plate support surface. The front side plate support surface is bent upward to form a first limiting fold edge. The upper edge of the first limiting fold edge is bent forward to form a second limiting fold edge. An oil filter screen is installed in the lower box, and the oil filter screen is located above the protective net. The front side of the oil filter screen is limited by the first limiting fold edge and the second limiting fold edge.

[0015] To further enhance the structural strength of the upper panel bracket, fixed flanges are formed on the left and right sides of the first limiting flange, and the fixed flanges are fixed to the front side plate support surface.

[0016] As a preferred embodiment of any of the above solutions, an oil fume extraction fan is installed inside the upper housing.

[0017] Compared with existing designs, the advantages of this utility model are as follows: the lower edge of the front side plate of the lower panel bracket of the range hood is bent backward to form a protective net, and the rear edge of the protective net is bent forward and downward to form a guide plate. The protective net, the guide plate and the bracket side plate form the air inlet of the lower box. The bracket side plate is fixed on the corresponding side wall of the lower box. The lower panel bracket is a one-piece piece, and the separately set oil guide strip is eliminated. This not only simplifies the materials, improves the material utilization rate, and reduces the processing, assembly and material management costs, but also ensures the overall rigidity of the lower panel assembly while simplifying the materials.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 and Figure 2As shown, the range hood in this embodiment includes an upper housing 1 and a lower housing 2 located below the upper housing 1. An exhaust fan 7 is installed inside the upper housing 1, and an oil filter 6 is installed inside the lower housing 2. A lower panel 3 is located on the front side of the lower housing 2, with an air inlet below the lower panel 3. Oil fumes are drawn in through the air inlet, flow upwards, pass through the oil filter 6, and then enter the exhaust fan 7. Typically, the lower panel 3 is made of glass. A lower panel bracket 4 is installed inside the lower housing 2, located on the back side of the lower panel 3, and the lower panel 3 is fixed to the lower panel bracket 4.

[0025] like Figures 3 to 5 As shown, the lower panel bracket 4 in this embodiment has a vertically arranged front side plate 41. The lower edge of the front side plate 41 is bent backward to form a protective net 42. The protective net 42 is located below the oil filter screen 6, serving both air intake and protection functions to prevent users from putting their hands into the fan system and causing injury. The protective net 42 extends diagonally downward from front to back. The rear edge of the protective net 42 is first bent vertically downward to form a vertical bend 45. The lower edge of the vertical bend 45 is bent forward and downward to form a guide plate 43. Support side plates 44 are provided on both the left and right sides of the protective net 42 and the guide plate 43. The protective net 42, the guide plate 43, and the support side plates 44 form an elongated triangle, which together form the air inlet of the lower housing 2. An oil cup 5 is installed at the bottom of the lower housing 2. The vertical projection of the lower edge of the guide plate 43 falls into the oil cup 5, and the vertical projection of the vertical bend 45 falls into the oil cup 5. The oil in the lower housing 2 can flow into the oil cup 5 through the vertical bend 45 and the guide plate 43.

[0026] The lower panel 3 and the lower panel bracket 4 are connected by silicone adhesive. Specifically, the leading edge of the bracket side panel 44 is bent outward to form an outer flange 47. The front side of the front side panel 41 forms a first adhesive surface, and the front side of the outer flange 47 forms a second adhesive surface. Both the first and second adhesive surfaces are bonded and fixed to the back of the lower panel 3. This improves the rigidity of the lower panel 3. Furthermore, the gap between the lower panel 3 and the lower panel bracket 4 is filled with silicone, preventing oil that has condensed on the upper part of the lower housing 2 from entering the gap. Instead, the oil flows from the inside of the lower panel bracket 4 along the oil path into the oil cup 5.

[0027] The lower plate bracket 4 is installed and fixed on the lower housing 2. The specific installation structure is as follows:

[0028] The lower edge of the guide plate 43 is bent to form a lower bottom flange 46. Screw holes 461 are provided on the lower bottom flange 46, and screws are used to fix the lower bottom flange 46 to the bottom of the lower housing 2 through the screw holes 461. Mounting holes 48 are provided on the bracket side plate 44, and these holes are also screw holes. Screws pass through these holes to fix the bracket side plate 44 to the corresponding side wall of the lower housing 2. A first buckle 49 is provided on the front side plate 41, and a second buckle 410 is provided on the outer flange 47 of the side plate. The lower panel bracket 4 is fixed to the corresponding side wall of the lower housing 2 through the first buckle 49 and the second buckle 410, ensuring a uniform gap between the lower panel 3 and the lower housing side plate. A mounting bracket 413 is formed on the back of the front panel 41. In this embodiment, there are three mounting brackets 413, which are spaced apart on the left and right. The mounting brackets 413 are fixed to the back plate of the lower housing 2 with screws, ensuring that the lower panel 3 and the side plate of the housing do not have any displacement steps after a fall. In this way, the bottom, left and right sides, front side and rear side of the lower panel bracket 4 are all connected and fixed to the lower housing 2, and the installation structure is very strong.

[0029] To increase the air intake area and reduce air intake resistance, a grille hole 414 is provided on the mounting bracket 413. Oil fumes can flow upwards through the grille hole 414, which helps improve the fume extraction effect and reduce noise. In addition, the mounting bracket 413 is also equipped with reinforcing ribs 419 and reinforcing flanges 420 to enhance structural strength.

[0030] In this embodiment, in order to improve the structural strength and rigidity of the lower panel bracket, the upper edge of the bracket side plate 44 is bent inward to form an upper side plate folded edge 411, and the lower edge of the bracket side plate 44 is bent inward to form a lower side plate folded edge 412. The upper side plate folded edge 411 is welded and fixed to the protective net 42, and the lower side plate folded edge 412 is welded and fixed to the guide plate 43.

[0031] In this embodiment, the upper edge of the front panel 41 is bent backward to form a front panel support surface 415. The front panel support surface 415 is bent upward to form a first limiting fold 416. The upper edge of the first limiting fold 416 is bent forward to form a second limiting fold 417. The first limiting fold 416 limits the oil filter screen 6 downward, while the second limiting fold 417 limits the oil filter screen 6 left and right and upward. In addition, to improve structural strength, fixed folds 418 are formed on the left and right sides of the first limiting fold 416. The fixed folds 418 are fixed to the front panel support surface 415, thereby improving the strength of the entire upper part of the lower panel bracket 4 and ensuring the stability of the oil filter screen 6 installation.

[0032] This range hood can be controlled by a voice module, which is equipped with a control module, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the range hood to perform corresponding operations, thereby realizing intelligent control of the range hood and improving the user experience.
