When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0047] The range hood is composed of fan cover, fume hood, fan and other parts. In order to improve production efficiency and prevent the fume hood assembly and fan cover assembly from turning over during assembly, the connection parts of the fan cover and fume hood are designed with folded edges, and then screwed directly from front to back with fasteners such as screws. Preventing condensed oil droplets from dripping through the inside of the range hood is a basic requirement for range hood design, so the oil guide structure design of the range hood is crucial.

[0048] Please refer to Figure 1 , the connecting parts of the smoke hood 300' and the fan hood 200' of the range hood 1000' are both provided with folding edges, which are connected by screws and other fasteners. The oil guiding scheme is to use the connecting folding edge as the oil guiding folding edge, and the flow path of the oil is as follows: the oil accumulated inside the volute is guided to the connecting folding edge of the fan hood 200' and the smoke hood 300' through the long oil nozzle, and finally drips naturally along the vertical surface of the oil guiding folding edge of the smoke hood 300' under the influence of gravity and flows to the bottom of the smoke hood 300' and the oil cup. The oil accumulated on the folding edge of the fan hood 200' will flow along the folding edge to its two lateral ends, forming a large area of ​​oil accumulation. In this structural form, during the operation of the range hood 1000', the oil guiding folding edge of the smoke hood 300' will be pulled by the wind during the dripping process, and it is easy to fly out from the air inlet provided on the smoke hood 300' and drip on the kitchen stove surface, causing the stove surface to be dirty.

[0049] Based on this, the utility model proposes a range hood, in which an oil guide structure is designed for the connection between the smoke hood and the fan hood, which takes into account both the connection with the fan hood and the oil guide function, and changes the flow path of the oil through the oil guide structure, thereby solving the problem of oil droplets flying into the air inlet.

[0050] For details, please refer to Figure 2 The range hood 1000 includes a fan cover 200, a smoke collecting cover 300 and an oil guiding structure 100. The fan cover 200 is provided with a fan assembly; the smoke collecting cover 300 is installed below the fan cover 200, the smoke collecting cover 300 is connected with the fan cover 200 to form a connecting portion 310, and the oil guiding structure 100 is arranged at the connecting portion 310 of the smoke collecting cover 300. The oil gathered in the volute in the fan cover 200 flows to the connecting portion between the fan cover 200 and the smoke collecting cover 300, and then flows along the connecting portion 310 to the oil guiding structure 100, and is guided by the oil guiding structure 100 to the side wall of the smoke collecting cover 300.

[0051] Furthermore, the oil guiding structure 100 includes a first oil guiding part 1 and a second oil guiding part 2, wherein the first oil guiding part 1 extends in the up and down directions and is used to be connected to the smoke hood 300; the second oil guiding part 2 is arranged at an angle to the first oil guiding part 1, the upper end of the second oil guiding part 2 is connected to the first oil guiding part 1, and the lower end is used to abut the side wall of the smoke hood 300; wherein the oil is guided to the side wall of the smoke hood 300 through the first oil guiding part 1 and the second oil guiding part 2.

[0052] The technical solution of the utility model improves the flow path of the oil droplets through the cooperation of the first oil guide part 1 and the second oil guide part 2. The first oil guide part 1 is connected to the smoke hood 300, and the second oil guide part 2 is arranged at an angle to the first oil guide part 1, so as to have an inclined oil guide surface. The oil flows down from the fan cover 200 through the first oil guide part 1 and the second oil guide part 2 and is guided to the side wall of the smoke hood 300, and finally flows along the side wall of the smoke hood 300 to the guide oil cup of the range hood 1000. The oil always adheres to the surface of the parts during the flow process, and will not drip in free fall. Therefore, even if there is wind influence, it will not cause splashing, thereby solving the problem of oil droplets flying into the air inlet.

[0053] It should be noted that the present invention does not limit the size of the angle between the first oil guide portion 1 and the second oil guide portion 2. It is preferred that the second oil guide portion 2 is inclined relative to the side wall of the smoke hood 300. The first oil guide portion 1 can be vertical or inclined. In some embodiments, the angle between the first oil guide portion 1 and the second oil guide portion 2 is greater than 90°.

[0054] Please refer to Figure 3 to Figure 4 In the first embodiment, the first oil guide part 1 and the second oil guide part 2 are integrally formed and made of flexible material. That is, the oil guide structure 100 is an integrally formed flexible component, and its material can be rubber, silicone, foamed flexible non-metallic material, etc. The oil guide structure 100 has a certain shape, but it is allowed to be compressed according to the actual installation conditions, and the installation accuracy requirement is low. Because the second oil guide part 2 is made of flexible material, it can be closely fitted with the side wall of the smoke hood 300 without causing damage to the side wall of the smoke hood 300.

[0055] It should be understood that the first oil guide part 1 and the second oil guide part 2 may both be made of flexible materials but assembled as one, or one of the first oil guide part 1 and the second oil guide part 2 may be made of flexible materials, in which case the two components are made of different materials and assembled as one.

[0056] Considering the coordination with fan cover 200, please refer to Figure 3, a boss 6 is provided at the connection point between the first oil guide part 1 and the second oil guide part 2 on the side facing away from the side wall of the smoke hood 300, and the boss 6 is used to abut against the fan cover 200 which is located above the smoke hood 300 and connected to the smoke hood 300. That is, the side of the first oil guide part 1 is tightly fitted with the fan cover 200, and at this time, the only part that plays the oil guiding function is the connection point with the second oil guide part 2. The first oil guide part 1 mainly plays the role of positioning and installation, and the second oil guide part 2 plays the main oil guiding function. The flow path of the oil is as follows: the oil flows out from the volute in the fan cover 200, is guided to the boss 6 through the lower end bend of the fan cover 200, and then is guided to the side wall of the smoke hood 300 through the second oil guide part 2, and finally is guided to the oil cup.

[0057] In order to prevent oil from accumulating on the boss 6, the upper surface of the boss 6 is arranged in a curved surface. For example, the top of the boss 6 can be designed to be an arc or an ellipse, and the curvature radius of the top of the boss 6 is increased, which is conducive to oil conduction.

[0058] It should be understood that the top of the boss 6 can be designed as a curved surface as a whole. Due to its flexible material, the curved surface can actually abut against the metal side of the fan cover 200, receiving the extrusion force to ensure the fit. The boss 6 can also be partially set as a straight edge, which can achieve a good positioning effect.

[0059] It should be understood that the first oil guide portion 1 can be vertically arranged and clamped between the two vertical surfaces at the folded edges of the fan cover 200 and the smoke hood 300; the first oil guide portion 1 can also be L-shaped and contact with the two folded edges of the fan cover 200 and the smoke hood 300 at the same time, and the present invention does not impose any restrictions on this.

[0060] Considering the installation of the oil guide structure 100 and the smoke hood 300, in one embodiment, a mounting protrusion 11 is convexly provided on the side surface of the first oil guide portion 1, and the mounting protrusion 11 is used to be clamped on the through hole of the smoke hood 300; the mounting protrusion 11 and the smoke hood 300 can be set to be hung or pressed, please refer to Figure 4 In this embodiment, the appearance of the mounting protrusion is similar to that of a nut, and the outer diameter is larger than the hole on the smoke hood 300. During assembly, the mounting protrusion can pass through the hole on the smoke hood 300 by deforming, and then restore its own size to cover the hole on the smoke hood 300, thereby preventing it from falling.

[0061] In another embodiment, a mounting hole 12 is provided on the first oil guide portion 1 for fasteners to pass through so as to be fixed on the smoke hood 300. The first oil guide portion 1 can be fixed on the smoke hood 300 by means of screws, latches and other structures.

[0062] In the first embodiment, a mounting protrusion and a mounting hole are provided on the first oil guide portion 1 at the same time. The mounting protrusion and the mounting hole can be provided in two, three or even more numbers according to the size of the first oil guide portion 1, so as to provide double insurance. During assembly, the mounting hole is circular, and the positioning hole on the smoke hood 300 is elliptical. The oil guide structure 100 is pre-installed on the smoke hood 300 through the positioning hole, and finally connected to the fan cover 200 through fasteners such as screws, so as to facilitate positioning and installation and improve production efficiency.

[0063] It should be noted that, since there may be errors in the bending processing of the fan cover 200 and the smoke hood 300, the facade of the connecting portion 310 may be vertical or slightly inclined. In this case, after the oil guide structure 100 is installed, the inclination of the second oil guide portion 2 will be slightly deviated. In order to avoid the separation of the second oil guide portion 2 from the side wall of the smoke hood 300 caused by such processing errors, in the initial design, the length of the second oil guide portion 2 can be slightly larger, and after contacting the side wall of the smoke hood 300, there is a small section of natural bending under force, so that the oil guide is not affected and the second oil guide portion 2 can be prevented from not contacting the side wall of the smoke hood 300. In this case, the end thickness of the second oil guide portion 2 can be set to be slightly thin.

[0064] Furthermore, in this embodiment, considering the convenience of installation of the oil guide structure 100 and the convenience of processing the smoke hood 300, the connecting portion 310 is bent to define the matching groove 5. In this way, when the bending knife bends this part during processing, it can smoothly withdraw from the bottom of the inverted U-shaped through groove, which has strong manufacturability and low cost. In addition, the connecting portion 310 forms a vertical surface, which can be easily installed with the first oil guide portion 1.

[0065] In the structural form of the first embodiment, the oil guide structure 100 is located between the fan cover 200 and the smoke collector 300, and is closely matched with the fan cover 200 and the smoke collector 300. It not only guides the oil to solve the problem of flying oil, but also plays a sealing role to prevent long-term oil circuits, and oil seeps from the connecting gap between the fan cover 200 and the smoke collector 300 to the outside of the smoke collector 300.

[0066] In order to further improve the adhesion of the oil droplets, a plurality of flanges or a plurality of inclined ribs may be provided on the surface of the second oil guiding structure 100 for guiding oil, so as to increase the contact area with the oil droplets.

[0067] Please refer to Figures 5 and 6In the second embodiment, at least one oil guide hole 3 is provided at the connection between the first oil guide part 1 and the second oil guide part 2. It should be understood that the oil guide hole 3 is provided across the first oil guide part 1 and the second oil guide part 2, and preferably the oil guide hole 3 is provided to be formed and pass through the first oil guide part 1 and the second oil guide part 2. On the one hand, the oil guide hole 3 forms an oil guide track, and the oil near the oil guide hole 3 will smoothly guide from the surface of the first oil guide part 1 to the surface of the second oil guide part 2 along the outer contour of the oil guide hole 3, and finally guide to the rear plane of the smoke hood 300 through the lower edge of the second oil guide part 2, and enter the oil cup; on the other hand, the setting of the oil guide hole 3 changes the connection strength between the first oil guide part 1 and the second oil guide part 2. Even if the oil guide structure 100 is made of rigid material, the second oil guide part 2 can also be a flexible and bendable surface relative to the first oil guide part 1. When processing the product, the first oil guide part 1 and the second oil guide part 2 can be placed in the same plane first, and then manually bent during subsequent assembly.

[0068] Furthermore, the width of the oil guide hole 3 is gradually reduced from its middle to its two ends in the upper and lower directions. The middle part of the oil guide hole 3 is the largest, and gradually reduces upward until a tip is formed, and gradually reduces downward until a tip is formed. In this embodiment, the cross-section of the oil guide hole 3 is hexagonal, and two tips are set in the upper and lower directions. Based on the fluid wall effect, the oil accumulated at the lower edge of the fan cover 200 will all be guided along the oil guide structure 100. The oil guide hole 3 tends to be narrow at the top and bottom and wide in the middle, so it has a unique guiding path, which effectively prevents oil droplets from flying out of the air inlet. Specifically, when the oil flows, the oil droplets gather at the upper tip of the oil guide hole 3, and then flow to the second oil guide part 2 in two directions. The oil in the lower and middle parts of the oil guide hole 3, part of it flows downward along the two opposite vertical sides of the oil guide hole 3, and part of it first converges to the tip of the lower part of the oil guide hole 3 and then flows downward.

[0069] In other embodiments, the oil guide hole 3 may also be arranged in a diamond shape, or other regular or irregular shapes.

[0070] Specifically, the oil guide holes 3 are arranged at intervals along the length direction of the first oil guide portion 1. It should be noted that the length direction of the first oil guide portion 1 is the length direction of the smoke hood 300, and the plurality of oil guide holes 3 can be arranged in the same straight line or staggered in the vertical direction.

[0071] Furthermore, a reinforcing rib 4 is provided at the connection between the first oil guide portion 1 and the second oil guide portion 2, and the reinforcing rib 4 extends along the length direction of the first oil guide portion 1. It is used to balance the connection strength and flexibility of the second oil guide portion 2 to the first oil guide portion 1. It should be noted that when the second oil guide portion 2 is manually bent during assembly, the reinforcing rib is also the corresponding fold position.

[0072] Furthermore, the plurality of oil guide holes 3 divide the reinforcing rib 4 into a plurality of rib segments 41, and each rib segment 41 is provided with a notch 42 at the end connected to the corresponding oil guide hole 3, and the size of the notch 42 is gradually expanded from the rib segment 41 where it is located to the direction of the corresponding oil guide hole 3. The notch 42 is a V-shaped through groove, with the tip located on the rib segment 41, and the open part is connected to the oil guide hole 3. The tip of the notch 42 is in a straight line with the center line of the oil guide hole 3, thereby reducing the strength of the reinforcing rib 4.

[0073] It should be understood that, since the first oil guiding portion 1 and the second oil guiding portion 2 are arranged at an angle, the oil guiding hole 3 and the notch 42 both cover two planes arranged at the angle.

[0074] It should be noted that, in this embodiment, the first oil guide portion 1 and the second oil guide portion 2 are used to be integrally formed with the smoke hood 300. That is, the material of the oil guide structure 100 is consistent with the material of the smoke hood 300, and the integrally formed structure is convenient for processing and manufacturing. In other embodiments, the oil guide structure 100 can be detachable, and its material can be a flexible material or a rigid material, and can be assembled with the smoke hood 300 by welding, bonding, riveting or screw connection, or one of the first oil guide portion 1 and the second oil guide portion 2 can be a flexible material, and the utility model does not limit this.

[0075] Specifically, when the oil guide structure 100 and the smoke hood 300 are integrally formed, the factors of convenience of processing are considered. In some embodiments, the upper end of the first oil guide portion 1 is bent to define a matching groove 5 with the side wall of the smoke hood 300 with the notch facing downward. That is, the connecting portion 310 is matched with the first oil guide portion 1 to form an inverted U-shaped through groove. In this embodiment, the first oil guide portion 1 is L-shaped and the connecting portion is I-shaped. In other embodiments, the connecting portion 310 is L-shaped and the first oil guide portion is I-shaped. In this way, when the bending knife bends this part during processing, it can smoothly withdraw from the bottom of the inverted U-shaped through groove, which has strong manufacturability and low cost.

[0076] Considering the collection of oil, in one embodiment, the length of the first oil guide portion 1 is gradually reduced from top to bottom, so as to collect the oil droplets to the middle as much as possible. In another embodiment, the length of the second oil guide portion 2 is gradually reduced from top to bottom. The effect of collecting the oil droplets to the middle can also be achieved. In the second embodiment, the lengths of the first oil guide portion 1 and the second oil guide portion 2 are both gradually reduced from top to bottom, and the length of the upper part of the second oil guide portion 2 is not greater than the length of the lower part of the first oil guide portion 1.

[0077] It should be noted that when the oil guide hole 3 is provided at the connection between the first oil guide part 1 and the second oil guide part 2, the lower end of the fan cover 200 is in contact with the first oil guide part 1, and the lower edge of the part is not lower than the upper edge of the oil guide hole 3. Thus, the oil flow path can be limited. Specifically, the bent part of the fan cover 200 fits with the upper section of the first oil guide part 1, so that the first oil guide part 1 can be connected.

[0078] In the second embodiment, the oil guide structure 100 has a simple structure, is easy to bend and form, and has low cost. The notch 42 is connected to the oil guide hole 3. The reinforcing rib 4 is located at the connection between the first oil guide part 1 and the second oil guide part 2, so the cross-section is triangular. Therefore, the reinforcing rib 4 and the oil guide hole 3 are connected to each other, and both are narrow at the top and bottom and wide in the middle, forming a smooth oil guide path. The design of the notch 42 further weakens the local strength of the reinforcing rib 4, which plays a role of pre-positioning, further improving the bending accuracy and bending efficiency during the processing of the second oil guide part 2.

[0079] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
