Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] In modern kitchen environments, range hoods, as essential ventilation and purification devices, are widely used in homes and commercial spaces. Their main function is to use a fan to generate negative pressure airflow, drawing in cooking fumes, steam, and odors produced during cooking. These are then filtered and separated before being discharged outdoors or purified and recirculated, thus maintaining clean indoor air and protecting human health. As consumers increasingly demand aesthetically pleasing, user-friendly, and easy-to-clean kitchen environments, range hood designs are gradually evolving towards higher efficiency, quieter operation, easier cleaning, and a more integrated aesthetic.

[0003] Existing range hoods lack effective structural coordination among their various functional components. For example, the air guide plate is mainly used for airflow guidance, the oil filter is used for filtration, and the oil guiding structure is set up independently. The three are often only physically connected, failing to form an efficient closed-loop oil guiding system. Especially in the connection area between the air guide plate and the oil filter, due to poor sealing or the lack of oil guiding design, condensed oil easily stagnates and drips along the edge, making it difficult to effectively guide it to the oil cup. Utility Model Content

[0008] Furthermore, the bottom of the oil guide beam is bent inward to form a bottom flange, and the two sides are bent inward to form side flanges. There are gaps between the two sides of the bottom flange and the rear end of the side flange, forming two oil leakage gaps.

[0009] Furthermore, the bottom of the bottom flange is bent downwards to form a lower flange; The oil guide tongue is formed by extending downward from the end of the downturned edge.

[0010] Furthermore, the lower surface of the oil guide beam is flush with the lower surface of the oil mesh, or the lower surface of the oil mesh protrudes from the lower surface of the oil guide beam.

[0011] Furthermore, decorative glass supports are also included; The middle part of the oil guide beam protrudes outward to form a mounting boss, which extends along the length of the oil guide beam. The decorative glass bracket is fixedly installed on the mounting boss.

[0012] Furthermore, the left and right ends of the oil guide beam are respectively provided with left connecting pieces and right connecting pieces extending to the left and right sides. The left connecting piece is connected to the left air guide plate, and the right connecting piece is connected to the right air guide plate to fix the oil guide beam to the inside of the smoke inlet.

[0013] Furthermore, an oil guiding gap is provided between the left end of the oil guiding beam and the left air guide plate; And / or an oil guiding gap is provided between the right end of the oil guiding beam and the right air guide plate; The oil guide gap is used to guide the condensed oil on the left or right air guide plate or the oil guide beam into the side of the oil mesh.

The above schematic diagram is only to illustrate the structural relationships related to the inventive point and is not intended as an actual scale of the product.

[0023] like Figures 1 to 10 As shown in the figure, a range hood according to an embodiment of this utility model includes multiple components such as a housing 1, a left air guide plate 2, a right air guide plate 3, an oil filter 4, an oil baffle 5, an oil guide beam 6, a switch box 7, and a decorative glass bracket 13. The housing 1 forms the main frame of the range hood, and its overall shape is rectangular. It is formed by stamping metal sheet and undergoes surface spraying treatment to improve corrosion resistance and aesthetics. A smoke inlet is provided in the central area of ​​the front side of the housing 1, which runs through the front and back of the housing 1, serving as the main channel for oil fumes to enter the interior of the range hood. The shape of the smoke inlet is preferably rectangular or inverted trapezoidal, with its width spanning the entire cooking area to ensure a wide coverage of oil fumes and improve smoke collection efficiency.

[0024] The left air guide plate 2 and the right air guide plate 3 are respectively located at the left and right edges of the smoke inlet, arranged symmetrically, and both are fixedly installed on the housing 1. The left air guide plate 2 and the right air guide plate 3 are made of stainless steel or galvanized steel plate, and have a certain curvature to form a good airflow guiding effect and prevent oil fumes from overflowing.

[0025] The right end of the left air guide plate 2 extends horizontally into the housing 1, forming a right connecting edge 17. This right connecting edge 17 is integrally formed from the main body of the left air guide plate 2 through stamping or bending, resulting in a plate-like structure. Similarly, the left end of the right air guide plate 3 also extends horizontally into the housing 1, forming a left connecting edge 18. This left connecting edge 18 is symmetrically arranged with the right connecting edge 17, has the same structural form, and is also formed from the body of the right air guide plate 3 through stamping or bending, possessing sufficient structural rigidity and load-bearing capacity. The right connecting edge 17 and the left connecting edge 18 are located on the left and right sides of the smoke inlet, respectively, and are opposite to each other, together forming a symmetrical connection structure system.

[0026] The oil mesh 4 is installed in the middle area of ​​the smoke inlet, between the left guide plate 2 and the right guide plate 3. Its main function is to intercept grease particles in the smoke and prevent them from entering the fan system and causing blockage. The oil mesh 4 is made of multiple layers of metal wire mesh, such as stainless steel diamond mesh or honeycomb mesh, which has high filtration efficiency and air permeability. The oil mesh 4 is installed vertically or slightly inclined, which facilitates the natural sliding of oil droplets after they condense on its surface. On the inner side of the top of the oil mesh 4 (i.e., the side facing the smoke chamber), there is a locking part 20. This locking part 20 is an elastic boss with an inverted buckle structure, i.e., a male lock, used to elastically engage with the locking part 19 on the oil guide beam 6.

[0027] The right connecting edge 17 and the left connecting edge 18 are provided with screw holes. These screw holes extend through the thickness direction of the connecting edges and are precisely positioned to correspond to the side edges of the oil mesh 4. During assembly, the left edge of the oil mesh 4 aligns with the right connecting edge 17 of the left air guide plate 2, and the right edge of the oil mesh 4 aligns with the left connecting edge 18 of the right air guide plate 3. Then, fasteners (such as self-tapping screws, machine screws, or bolt assemblies) are passed through the mounting holes on the side of the oil mesh 4 and screwed into the screw holes on the right connecting edge 17 and the left connecting edge 18, thereby achieving a firm connection between the oil mesh 4 and the left and right air guide plates 3.

[0028] The oil guide beam 6 is one of the core structural components of this invention. It is located between the front end of the housing 1 and the front end of the oil mesh 4, with the rear end of the oil guide beam 6 overlapping the front end of the oil mesh 4. The oil guide beam 6 is generally transversely strip-shaped, extending along the width of the smoke inlet, with its left and right ends connected to the left air guide plate 2 and the right air guide plate 3, respectively. Specifically, the left end of the oil guide beam 6 has a left connecting piece 15 extending to the left, and the right end has a right connecting piece 16 extending to the right. Both connecting pieces are metal sheet structures formed by stamping and bending from the main body of the oil guide beam 6, possessing sufficient strength and rigidity. The left connecting piece 15 is connected to the left air guide plate 2 by screws or bolts, and the right connecting piece 16 is also connected to the right air guide plate 3 by screws or bolts, thereby firmly suspending the oil guide beam 6 above the inner side of the smoke inlet. This connection method not only achieves reliable fixation of the oil guide beam 6 but also makes it an important transverse reinforcing component connecting the left and right air guide plates 3, improving the torsional resistance of the overall structure.

[0029] Oil guide gaps of a certain size are reserved between the left end of the oil guide beam 6 and the left air guide plate 2, and between the right end of the oil guide beam 6 and the right air guide plate 3. These oil guide gaps are intentionally designed functional structures, with a width generally controlled between 0.5 mm and 3 mm. This not only meets the requirements of thermal expansion and contraction but also effectively avoids stress concentration problems caused by complete sealing. More importantly, these oil guide gaps constitute important oil drainage channels: when oil droplets condense due to the cooling of high-temperature oil fumes at one end of the left air guide plate 2 or the right air guide plate 3, or at both ends of the oil guide beam 6, these oil droplets flow downwards along the oil guide gaps and are guided to the side area of ​​the oil mesh 4. Since the side of the oil mesh 4 usually has an oil guide groove or oil collection edge, this oil can eventually flow smoothly to the oil cup for recycling. This design effectively solves the problem of oil accumulation and dripping at the edge of the air guide plate in traditional range hoods, and realizes a multi-stage oil guiding path of "air guide plate → oil guiding beam 6 → oil mesh 4 → oil cup", which greatly improves the oil leakage prevention performance.

[0030] The bottom structure of the oil guiding beam 6 is designed to achieve a stable connection with the oil mesh 4 and to guide the oil. First, the bottom of the oil guiding beam 6 is bent inward to form a bottom flange 21, and the two sides are bent inward to form side flanges 22; gaps are left between the two sides of the bottom flange 21 and the rear end of the side flanges 22, forming two oil leakage gaps 23.

[0031] The position of the oil leakage gap 23 corresponds to that of the oil guide gap.

[0032] The bottom of the bottom flange 21 is bent downward to form a lower flange 12. The lower flange 12 extends continuously along the length of the oil guide beam 6 and is formed by stamping and bending a metal sheet in one go, which has good structural consistency.

[0033] An oil-guiding tongue 11 extends downward from the free end (i.e., the end point) of the lower flange 12. This oil-guiding tongue 11 is a convex structure formed by stamping from the end of the lower flange 12, and is generally tongue-shaped or hook-shaped. The position of the oil-guiding tongue 11 is directly opposite the top surface of the oil mesh 4. In the assembled state, the bottom surface of the oil-guiding tongue 11 overlaps with the upper surface of the top of the oil mesh 4, forming a surface contact, which plays a supporting and positioning role. At the same time, since the oil-guiding beam 6 itself is higher than the oil mesh 4, the oil condensed on its surface can flow down along the oil-guiding tongue 11 under the action of gravity and drip directly onto the surface of the oil mesh 4, avoiding overflow. Furthermore, the lower surface of the oil-guiding beam 6 is flush with the lower surface of the oil mesh 4 in appearance, or the lower surface of the oil mesh 4 protrudes slightly from the lower surface of the oil-guiding beam 6 by 1~2mm. When the two are aligned, the front of the machine presents a seamless visual effect, with a neat and beautiful appearance; when the front surface of the oil mesh 4 protrudes, the oil droplets gathered at the lower end of the oil guide beam 6 can flow smoothly onto the oil mesh 4, further preventing oil from splashing outward from the front, thus combining functionality and aesthetic value.

[0034] To facilitate quick installation, removal, and secure fixing of the oil mesh 4, a locking part 19 is provided at the bottom of the oil guide beam 6. This locking part 19 is located on the body of the oil guide beam 6 or the lower flange 12, specifically in the form of a female locking buckle, i.e., an internal receiving cavity with a locking groove. Correspondingly, a matching locking part 20 is provided on the inner side of the top of the oil mesh 4. This locking part 20 is a male locking structure, i.e., an elastic boss with a reverse buckle. When installing the oil mesh 4, the operator pushes the oil mesh 4 upward, aligning the locking part 20 and inserting it into the locking part 19. As the pushing process proceeds, the elastic boss undergoes slight deformation under pressure, returning to its original shape after passing the slot entrance, achieving automatic locking. This elastic locking structure allows the oil mesh 4 to be installed and removed without tools, greatly facilitating daily cleaning and maintenance. At the same time, the presence of the oil guide tongue 11 provides additional top support, working together with the locking structure to ensure that the oil mesh 4 will not loosen or fall off during operation.

[0035] At the top of the oil guiding beam 6, there are also mounting interfaces for other functional components. The top of the oil guiding beam 6 is bent inward to form an upturned edge 9. This upturned edge 9 not only enhances the structural rigidity of the top of the oil guiding beam 6, but also has a positioning groove 10 machined on its surface. The positioning groove 10 is a rectangular or U-shaped opening with moderate depth and precise positioning.

[0036] A switch window is provided on the upper front side of the housing 1, and the switch box 7 is located inside the housing 1 at the switch window. The rear end of the switch box 7 is located at the front end of the oil guide beam 6. The switch box 7 serves as the load-bearing structure for the control panel, and its lower back is provided with an elastic support 8, which is a plastic claw or metal spring with a certain degree of elasticity. During assembly, the switch box 7 is inserted from the front, and the elastic support 8 on its back is compressed and deformed under the thrust, entering the positioning groove 10 and then springing back to achieve snap-fit ​​positioning. This connection method eliminates the need for additional fasteners, enabling rapid installation and precise positioning of the switch box 7, thus improving production efficiency and assembly accuracy.

[0037] In addition, the range hood includes a decorative glass bracket 13 for mounting the front decorative glass panel, enhancing the product's grade and modern feel. The mounting position of the decorative glass bracket 13 is supported by the oil-guiding beam 6. Specifically, in the middle region of the oil-guiding beam 6, a mounting boss 14 protrudes outward (i.e., forward), extending a certain distance along the length of the oil-guiding beam 6. This mounting boss 14 has a T-shaped or rectangular cross-section, providing sufficient load-bearing area. The decorative glass bracket 13 is fixedly mounted to this mounting boss 14 using screws or clips, ensuring a secure and reliable connection. Because the mounting boss 14 is integrated into the oil-guiding beam 6, no additional support frame is needed, simplifying the structure, reducing costs, and ensuring spatial coordination of the front components.

[0038] The oil baffle 5, serving as a component to prevent oil fumes from escaping and to obscure the internal structure, is positioned above the oil guide beam 6. An oil drain port is located at the rear end of the oil baffle 5, which is flush against the rear end of the oil guide beam 6. The oil baffle 5 is generally curved or flat, and its material can be tempered glass or metal. Its lower rear edge is flush against the upper surface of the oil guide beam 6 and secured with screws or bolts. An oil drain port is located at the bottom of the oil baffle 5, corresponding to the top of the oil guide beam 6. This allows oil condensed on the surface of the oil baffle 5 to flow through the drain port into the inner surface of the oil guide beam 6, ultimately converging into the oil mesh 4 or oil cup. During assembly, ensure the oil drain port is completely flush against the top of the oil guide beam 6 to prevent gaps that could lead to oil leakage or scale buildup. This design achieves seamless integration between the oil baffle 5 and the oil guiding system, further improving the overall closed-loop oil guiding system of the machine.

[0039] Specifically, the oil guide tongue 11 corresponds to the position of the oil leak port.

[0040] In addition, the oil mesh 4 is provided with multiple strip-shaped mesh holes extending in the front-to-back direction, and the top surface of the oil mesh 4 is provided with upward-extending annular ribs along the edges of the strip-shaped mesh holes. An oil guiding channel is formed on the top surface of the oil mesh and between two adjacent annular ribs. The oil guiding tongue 11 overlaps the top surface of the oil mesh 4, so that the oil guiding tongue 11 corresponds to the oil guiding channel.

[0041] In summary, the range hood provided by this utility model, through its multi-functional integrated structure of the oil-guiding beam 6, achieves multiple connections and functional coordination with the left air guide plate 2, right air guide plate 3, oil filter 4, switch box 7, decorative glass bracket 13, and oil baffle 5. This not only improves structural stability, oil guiding efficiency, and leak-proof performance, but also facilitates assembly and maintenance, demonstrating promising prospects for industrial application. This design fully considers the needs for ease of cleaning, structural reliability, and aesthetic integration in practical use, making it a technologically advanced and highly practical range hood solution.
