Description

Technical Field

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

[0002] Existing range hoods often have shortcomings in their air inlet design. For example, some range hoods use vertical or tapered air inlets, or have a fixed and relatively small air inlet area. This design leads to several problems: Poor smoke collection: Due to the limited air inlet area or unreasonable airflow guidance, a large negative pressure zone cannot be effectively formed in the initial stage of smoke generation (i.e., the stage when smoke spreads above the cookware), causing some smoke to escape and not be sucked in in time. Easy smoke diffusion: When the amount of smoke suddenly increases (such as during stir-frying), traditional air inlets may not be able to quickly contain and guide all the smoke, causing it to spread in all directions, affecting the kitchen environment and the user's health. Therefore, there is an urgent need for a range hood structure that can expand the negative pressure zone, improve smoke capture efficiency, and effectively suck in smoke in its initial stage of generation. Utility Model Content

[0003] To solve the above problems, this technical solution provides a funnel-shaped range hood.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A funnel-shaped range hood, including

[0006] The casing is cylindrical and has an interface at its lower end;

[0007] An air inlet shroud is disposed on the housing and connected to the interface; the air inlet shroud is provided with an air inlet that connects the interface to the outside, and the air inlet shroud is flared in shape with its outer diameter gradually increasing from the interface to the air inlet, so that the air inlet gradually expands.

[0008] As described above, in a flared range hood, the air inlet hood includes an outwardly expanding section and a flat opening section.

[0009] As described above, in a funnel-shaped range hood, the housing includes a lower plate disposed on the interface, and the air inlet hood is connected to the lower plate by fasteners.

[0010] As described above, a flared range hood further includes a lamp body located inside the air inlet hood on the housing, and a detachable mechanism located between the lower plate and the lamp body. The detachable mechanism allows the lamp body to be switched to a connected state where both ends are connected to the lower plate; or to a detached state where both ends of the lamp body are separated from the lower plate; or to a semi-detached state where one end of the lamp body is connected to the lower plate and the other end is separated from the lower plate.

[0011] As described above, in a funnel-shaped range hood, the detachable mechanism includes a hinge rod, a limiting groove on the lamp body, and a limiting member connected to the lamp body. The upper end of the hinge rod is connected to the lower plate, and the lower end is limited by the limiting member to the limiting groove, so that the lamp body can be rotated relative to the hinge rod.

[0012] As described above, in a funnel-shaped range hood, the hinge rod is U-shaped and has a positioning groove at its lower end. The limiting groove is for the lower end of the hinge rod to be inserted into. A support ring and a positioning ring are protruding on the inner wall of the limiting groove. The positioning ring is inserted into the positioning groove to restrict the lateral movement of the lamp body relative to the hinge rod.

[0013] As described above, in a funnel-shaped range hood, the lower plate is provided with mounting holes, the upper end of the hinge rod is provided with threads, and the upper end of the hinge rod passes through the mounting holes and is connected to a nut for fixation.

[0014] As described above, in a flared range hood, the detachable mechanism further includes a connecting rod disposed on the lower plate and a connecting part disposed on the lamp body, wherein the connecting rod and the connecting part are detachably connected.

[0015] In the above-described trumpet-shaped range hood, the connecting rod and the hinge rod are located at opposite ends of the lamp body.

[0016] As described above, in a flared range hood, the radius of the outward expansion section is 51.6mm ± 5mm.

[0017] The beneficial effects of this application are:

[0018] This utility model provides a funnel-shaped range hood. The funnel-shaped air inlet hood can form an initial negative pressure zone with a wider coverage area, which can cover the oil fumes in the early stage of oil fume generation (above the cookware), effectively preventing the oil fumes from spreading outward, thereby significantly improving the oil fume capture efficiency and extraction rate.

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] A funnel-shaped range hood, including

[0025] The housing 1 is cylindrical and has an interface 11 at its lower end;

[0026] An air inlet shroud 2 is disposed on the housing 1 and is connected to the interface 11. The air inlet shroud 2 is provided with an air inlet 21 that connects the interface 11 to the outside. The air inlet shroud 2 is in the shape of a trumpet with its outer diameter gradually increasing from the interface 11 to the air inlet 21, so that the air inlet 21 gradually increases in size.

[0027] This utility model provides a funnel-shaped range hood. The funnel-shaped air inlet hood can form an initial negative pressure zone with a wider coverage area, which can cover the oil fumes in the early stage of oil fume generation (above the cookware), effectively preventing the oil fumes from spreading outward, thereby significantly improving the oil fume capture efficiency and extraction rate.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, the air inlet hood 2 includes an outwardly expanding section 23 and a flat opening section 24. By providing the flat opening section, a larger smoke collection area can be ensured for the overall air inlet hood.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the housing 1 includes a lower plate 12 disposed on the interface 11, and the air inlet shroud 2 is connected to the lower plate 12 by fasteners. This provides a stable and detachable connection between the air inlet shroud and the housing, making the installation, maintenance, or cleaning of the air inlet shroud simple and convenient.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the housing 1 is also provided with a lamp body 3 located inside the air inlet cover 2, and a detachable mechanism 4 located between the lower plate 12 and the lamp body 3. The detachable mechanism 4 allows the lamp body 3 to be switched to a connected state where both ends are connected to the lower plate 12; or to a disassembled state where both ends of the lamp body 3 are separated from the lower plate 12; or to a semi-disassembled state where one end of the lamp body 3 is connected to the lower plate 12 and the other end is separated from the lower plate 12. The detachable mechanism provides multiple working states for the lamp body: the connected state ensures normal lighting; the disassembled state facilitates thorough cleaning or replacement of the lamp body; and the semi-disassembled state allows the lamp body to hang, facilitating inspection of the back of the lamp body, or providing ample operating space for cleaning or inspection of the interior of the housing, greatly improving the convenience of maintenance.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the detachable mechanism 4 includes a hinge rod 41, a limiting groove 42 provided on the lamp body 3, and a limiting member 43 connected to the lamp body 3. The upper end of the hinge rod 41 is connected to the lower plate 12, and the lower end is limited by the limiting member 43 to the limiting groove 42, so that the lamp body 3 can rotate relative to the hinge rod 41. This achieves a hinged connection of the lamp body, allowing the lamp body to rotate around the hinge rod.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the hinge rod 41 is U-shaped, and its lower end is provided with a positioning groove 411. The limiting groove 42 allows the lower end of the hinge rod 41 to be inserted. A support ring 421 and a positioning ring 422 protrude from the inner wall of the limiting groove 42. The positioning ring 422 is inserted into the positioning groove 411 to limit the lateral movement of the lamp body 3 relative to the hinge rod 41. The cooperation between the U-shaped hinge rod, the positioning ring, and the positioning groove allows the lamp body to flip while effectively limiting the horizontal swaying and movement of the lamp body, ensuring the stability of the lamp body in the connected state and the semi-disassembled state, and avoiding abnormal noise or wear caused by loosening.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the lower plate 12 is provided with a mounting hole 121, and the upper end of the hinge rod 41 is threaded. The upper end of the hinge rod 41 passes through the mounting hole 121 and is connected to a nut for fixation. The use of a threaded and nut connection method results in a simple structure, low cost, and facilitates the installation and disassembly of the hinge rod, providing convenience for the maintenance of the entire detachable mechanism.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the detachable mechanism 4 also includes a connecting rod 44 disposed on the lower plate 12 and a connecting part 45 disposed on the lamp body 3, wherein the connecting rod 44 and the connecting part 45 are detachably connected. By adding a connecting rod and connecting part on the other side, which cooperate with the hinge rod on one side, the lamp body is securely locked in the normal working position, preventing it from flipping or falling off due to vibration or accidental contact during use, thus ensuring the reliability of the product. The detachable connection between the connecting rod 44 and the connecting part 45 can be achieved through magnetic attraction, threads, snap-fit, or other methods.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting rod 44 and the hinge rod 41 are respectively located at opposite ends of the lamp body 3. By setting the two-point fixing mechanism at opposite ends of the lamp body, the weight of the lamp body can be evenly supported from both sides, making the fixing of the lamp body more balanced and stable, and avoiding deformation or connection failure that may be caused by unilateral force.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the radius of the outward expansion section 23 is 51.6mm ± 5mm. This specific size range is an optimized design that achieves the best balance between the outward expansion angle, airflow smoothness, and overall structural compactness, ensuring optimal negative pressure zone expansion and fume extraction within a limited installation space.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the lower end of the housing 1 is bent inward to form a bent portion 14. The bent portion 14 supports the lower plate 12. The upper end of the air inlet shroud 2 is recessed with a groove 22 to accommodate the bent portion 14, and the bent portion 14 is fitted around the outer periphery of the groove 22. The bent portion helps to strengthen the interface, facilitates support of the lower plate, and allows for alignment with the groove.

[0038] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
