They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] The present invention will be further described in detail below with reference to the embodiments.

[0051] like Figures 1 to 7 As shown, this embodiment provides an oil guiding structure for a range hood, including: a smoke collection hood 1 with a smoke collection port 11 and an oil filter installed on the smoke collection port 11; an oil cup 4 located below the smoke collection hood 1; an oil collection frame 2 with an oil collection groove 201 inside that is suitable for cooperating with the edge of the oil filter, the oil collection frame 2 being installed on the inner peripheral edge of the smoke collection port 11; and an oil guiding box 3 installed on the smoke collection hood 1, having a guiding chamber inside that connects the oil collection groove 201 and the oil cup 4, which can directly guide the oil droplets collected in the oil collection frame 2 into the oil cup 4.

[0052] By adding an oil guide box 3 between the oil collection frame 2 and the oil cup 4, all the oil droplets produced by the range hood can be guided into the oil cup 4, preventing oil droplets from overflowing from other parts of the machine onto the stove, thus avoiding pollution of the kitchen environment and the occurrence of safety accidents.

[0053] In this embodiment, the oil guiding box 3 is a shell structure with a flow guiding chamber. The oil guiding box 3 can not only guide oil droplets but also temporarily store oil droplets, effectively avoiding the phenomenon of oil droplet overflow caused by excessive oil droplets.

[0054] Further, the oil collecting frame 2 includes an upper edge frame, a lower edge frame, and side edge frames respectively connected to the two sides of the upper and lower edge frames. The oil guiding box 3 is installed on the lower side edge of the smoke collecting hood 1 corresponding to the lower edge frame. The bottom wall 32 of the oil guiding box 3 is provided with an outlet structure communicating with the oil receiving cup 4. The peripheral wall of the oil guiding box 3 is provided with an inlet structure communicating with the oil collecting groove 201.

[0055] The oil droplets generated in the range hood are collected by the oil screen and then collected into the oil collecting frame 2. The oil droplets collected in the oil collecting frame 2 will flow along the internal oil collecting groove 201 to the lower edge frame under the action of gravity. The oil droplets in the lower edge frame will enter the internal flow guiding chamber from the inlet structure of the oil guiding box 3 and be directly discharged into the oil receiving cup 4 from the outlet structure of the oil guiding box 3, without flowing through the smoke collecting hood 1. This effectively solves the problem of oil hanging and oil leakage on the smoke collecting hood 1, and the oil fume cannot be efficiently and smoothly discharged, so that the practical performance of the range hood is higher and the use demand of the user is better met.

[0056] Further, as shown in Figures 1 to 4 , the lower side edge of the smoke collecting hood 1 is provided with a flange groove 12. The flange groove 12 is formed by outwardly extending the lower side edge of the smoke collecting hood 1 and then upwardly folding the flange groove 12. The bottom of the oil guiding box 3 is embedded and installed in the flange groove 12. By embedding and installing the oil guiding box 3 in the flange groove 12, the oil guiding box 3 is more convenient to disassemble and install, easy to clean, effectively ensures the cleaning effect of the inside of the range hood, and also facilitates the oil guiding box 3 to be directly disassembled and the oil droplets inside the oil guiding box 3 to be poured out.

[0057] Further, as shown in Figure 1 , the bottom wall of the flange groove 12 is provided with a first avoiding hole 16 corresponding to the outlet structure. The first avoiding hole 16 is provided to avoid the outlet structure, so that the outlet structure can directly pass through the first avoiding hole 16 without passing through the smoke collecting hood 1, avoiding the oil droplets in the oil guiding box 3 from being accumulated and stuck on the smoke collecting hood 1 when being discharged.

[0058] Further, as shown in Figure 3 , Figure 4 , Figure 6As shown, the outlet structure comprises an oil guiding hole 321 opened in the bottom wall 32 of the oil guiding box 3 and an oil guiding hole column 322 connected to the oil guiding hole 321, the outlet end of the oil guiding hole column 322 penetrates through the first avoiding hole 16 and communicates with the oil receiving cup 4. The upper inlet end of the oil guiding hole column 322 communicates with the flow guiding chamber inside the oil guiding box 3, and the lower outlet end penetrates through the first avoiding hole 16 and communicates with the chamber inside the oil receiving cup 4, so that the oil guiding structure no longer flows through the smoke collecting hood 1 when guiding oil to the oil receiving cup 4, and the assembly between the oil guiding box 3 and the smoke collecting hood 1 is more stable.

[0059] Further, the oil guiding hole column 322 can be a cylindrical structure, or the oil guiding hole column 322 is an outwardly expanding columnar structure with gradually increasing cross section from the inlet end to the outlet end, so that the oil droplets can be more easily and smoothly discharged, avoiding the oil droplets from being blocked in the oil guiding hole column 322, and improving the oil guiding effect of the oil guiding box 3.

[0060] Preferably, the bottom wall 32 of the oil guiding box 3 is inclined downward, and the outer edge of the bottom wall 32 is inclined toward the direction of the oil guiding hole 321, forming a converging shape converging toward the oil guiding hole 321, which facilitates the collection and discharge of oil droplets in the oil guiding box 3 and avoids the accumulation of some oil droplets at the corner position of the oil guiding box 3.

[0061] Alternatively, in another scheme, the bottom wall 32 of the oil guiding box 3 is provided with a downwardly recessed profile structure, the profile structure forms a groove structure lower than the inner surface of the bottom wall 32 of the oil guiding box 3, and the oil guiding hole 321 is opened at the bottommost position of the groove structure, which can facilitate the collection and discharge of oil droplets in the oil guiding box 3 and avoid the accumulation of oil droplets in the oil guiding box 3.

[0062] Further, the oil collecting frame 2 comprises an inner circumferential side wall, an outer circumferential side wall and an oil collecting bottom wall, the outer circumferential side wall is close to the inner circumferential edge of the inner edge of the smoke inlet 11, the inner circumferential side wall is away from the inner circumferential edge of the inner edge of the smoke inlet 11, and the inner space of the inner circumferential side wall, the outer circumferential side wall and the oil collecting bottom wall of the oil collecting frame 2 together form an oil collecting groove 201 with an open top.

[0063] Preferably, the inner circumferential side wall and / or the outer circumferential side wall are gradually inclined outward, and the oil droplets will collect into the oil collecting groove 201 along the inner circumferential side wall and / or the outer circumferential side wall of the oil collecting frame 2, and the above design increases the opening area of the open top of the oil collecting groove 201 and improves the oil collecting effect of the oil collecting frame 2.

[0064] Further, as shown in FIG. 6, the oil guiding box 3 is provided with a plurality of oil guiding holes 321, and the oil guiding hole column 322 is connected to each oil guiding hole 321. Figure 3 and Figure 4As shown, the outer peripheral side wall of the oil collecting frame 2 includes the outer side wall 21 of the lower frame, and the inner peripheral side wall of the oil collecting frame 2 includes the inner side wall 22 of the lower frame. The oil guiding box 3 includes a diversion side wall 31 extending towards the lower frame of the oil collecting frame 2, and the top part of the diversion side wall 31 extends to a position outside the outer side wall 21 of the lower frame of the oil collecting frame 2.

[0065] The inlet structure includes an insertion port 316 opened on the diversion side wall 31. A diversion nozzle 211 protruding is provided on the outer side wall 21 of the oil collecting frame 2 or on the oil collecting bottom wall of the oil collecting frame 2. The diversion nozzle 211 can penetrate through the insertion port 316 and extend into the oil guiding box 3 to guide the oil droplets in the oil collecting groove 201 into the oil guiding box 3.

[0066] The inlet end of the diversion nozzle 211 is communicated with the inside of the oil collecting groove 201, and the outlet end extends towards the direction of the insertion port 316 and penetrates through the insertion port 316 to be communicated with the diversion chamber inside the oil guiding box 3, so that the oil droplets collected in the oil collecting frame 2 will not flow into the smoke collecting hood 1 when entering the oil guiding box 3, avoiding the problem that the smoke collecting hood 1 is long-term hanging with oil, which is not only difficult to clean, but also affects the smoke exhausting effect of the smoke collecting hood 1 and the use performance of the range hood.

[0067] The inlet end of the diversion nozzle 211 can be connected to the oil collecting bottom wall of the oil collecting frame 2 or to the outer side wall 21 of the oil collecting frame 2. Preferably, the diversion nozzle 211 is integrally provided with the oil collecting frame 2 and is formed by the partial outer side wall 21 of the oil collecting frame 2 extending towards the direction of the diversion side wall 31.

[0068] Specifically, as Figures 1 to 4 shown, the position of the outer side wall 21 of the oil collecting frame 2 corresponding to the insertion port 316 is provided with a notch, forming an opening similar to a "U" shape, and converging and extending towards the direction of the insertion port 316 along the two side edges and the lower edge of the opening, forming a diversion nozzle 211 similar to a dustpan shape.

[0069] The diversion nozzle 211 is inserted into the insertion port 316, on the one hand, it plays a role in guiding the oil droplets into the oil guiding box 3, and on the other hand, it can also play a role in plug-in positioning, improving the assembly efficiency of the oil collecting frame 2 and the oil guiding box 3.

[0070] In this embodiment, the diversion nozzle 211 is not limited to the above structure, and other existing structures with a diversion flow channel inside that can be inserted into the insertion port 316 and extend into the oil guiding box 3 are all acceptable, such as a columnar diversion structure with a closed outer periphery and a hollow interior.

[0071] Further, as Figures 3 to 5As shown, the inner wall surface of the flow guide side wall 31 is provided with a drainage baffle rib 317 on both sides of the plug interface 316, and a drainage flow channel is defined between the two drainage baffle ribs 317. The drainage baffle rib 317 extends downward from the upper edge of the plug interface 316 to the bottom wall 32 of the oil guiding box 3. The drainage baffle rib 317 plays a role in guiding oil droplets, so that the oil droplets can quickly flow along the drainage flow channel between the two drainage baffle ribs 317 to the outlet structure of the bottom wall 32 of the oil guiding box 3, improving the oil guiding efficiency.

[0072] Preferably, the outlet structure of the bottom wall 32 of the oil guiding box 3 is located directly below the plug interface 316, and the outlet structure is located between the two drainage baffle ribs 317. The flow guide nozzle 211 is plugged into the oil guiding box 3 through the plug interface 316. The oil droplets flow into the oil guiding hole 321 on the bottom wall 32 of the oil guiding box 3 along the drainage flow channel defined between the two drainage baffle ribs 317, and are guided into the oil receiving cup 4 by the oil guiding hole column 322. The drainage baffle rib 317 can improve the oil guiding effect.

[0073] Further, as shown in Figure 3 and Figure 4 、 Figure 7 As shown, the oil collecting port 11 is provided with a limiting baffle wall 13 abutting against the outer side wall 21 of the oil collecting frame 2. The limiting baffle wall 13 is formed by bending the inner peripheral edge of the oil collecting port 11 upward. The flow guide side wall 31 includes a flat section 311 and a bent section 312 formed by bending the outer extension of the upper edge of the flat section 311 upward.

[0074] The flow guide side wall 31 is arranged in close contact with the smoke collecting cover 1. The limiting baffle wall 13 is located between the outer side wall 21 of the oil collecting frame 2 and the bent section 312 of the flow guide side wall 31. A second avoiding hole 17 is formed in the limiting baffle wall 13 corresponding to the position of the plug interface 316, which can be passed through by the flow guide nozzle 211.

[0075] In the above scheme, the second avoiding hole 17 is provided for avoiding the flow guide nozzle 211. The flow guide nozzle 211 extends into the oil guiding box 3 through the second avoiding hole 17 and the plug interface 316 in sequence. When the oil droplets are guided into the oil guiding box 3 by the oil collecting frame 2, they will not enter the smoke collecting cover 1, avoiding the accumulation of oil droplets on the smoke collecting cover 1. Moreover, through the above design, the assembly effect of the oil collecting frame 2, the smoke collecting cover 1 and the oil guiding box 3 is enhanced, and the stability of the cooperation among them is improved.

[0076] Further, the upper edge of the limiting baffle wall 13 is higher than the upper edge of the outer side wall 21 of the oil collecting frame 2, the limiting baffle wall 13 extends horizontally towards the inner side wall 22 of the oil collecting frame 2 to form a connecting wall 14, the upper edge of the bent section 312 of the flow guide side wall 31 extends horizontally outward to form an overlapping wall 313 overlapping above the connecting wall 14, and the limiting steps are formed between the limiting baffle wall 13 and the connecting wall 14 and between the bent section 312 and the overlapping wall 313, thereby enhancing the stability of the cooperation between the smoke collecting cover 1 and the oil guiding box 3.

[0077] The outer edge of the connecting wall 14 extends upward to form a limiting flange 15, preferably, the limiting flange 15 is inclined towards the direction of the flow guide side wall 31, the outer edge of the overlapping wall 313 extends upward to form a cooperating flange 314 abutting against the limiting flange 15, and the limiting cooperation between the limiting flange 15 and the cooperating flange 314 plays a supporting limiting role, thereby avoiding the position of the oil guiding box 3 from moving.

[0078] Further, as shown in Figures 2 to 6 , a plurality of first bolt columns 315 are arranged on the overlapping wall 313, the first bolt columns 315 are spaced apart and injection molded on the overlapping wall 313, a plurality of first threaded holes are formed on the connecting wall 14, and the top of the oil guiding box 3 is connected and fixed to the smoke collecting cover 1 by screws passing through the first threaded holes and the first bolt columns 315 in sequence, the screws extend into the first threaded holes and the first bolt columns 315 from the lower side, and the screw caps are hidden below the connecting wall 14, so that the screws cannot be seen from the outside, thereby improving the appearance of the whole machine.
