Description

Technical Field

[0001] This utility model relates to the technical field of kitchen appliances, and in particular to a range hood with an oil-guiding structure. Background Technology

[0002] Cooking fumes not only contain a large number of harmful substances that can harm human health if inhaled for a long time, but also spread indoors, causing pollution to walls, furniture, etc. Installing a high-efficiency range hood in the kitchen can effectively remove cooking fumes from the room, thereby ensuring indoor hygiene and improving the user's living environment.

[0003] In the prior art, a range hood includes a casing and a fan. The fan is installed inside the casing, which also contains a smoke collection chamber and an air duct. The fan generates negative pressure to draw cooking fumes into the smoke collection chamber, and then exhausts them outdoors through a pre-set air duct.

[0004] However, when oil fumes pass through the inner cavity at high speed, some oil molecules condense and adhere due to the decrease in temperature or collision with the cavity wall. After long-term use, a thick layer of grease will form on the inner cavity wall, causing the inside of the casing to emit odors and breed bacteria. At the same time, the grease adhering to the various parts of the smoke collection chamber may be softened by high temperature during the next start-up and may be left directly on the kitchen countertop along with the opening of the smoke guide plate, seriously affecting the user experience and the lifespan of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a range hood with an oil guiding structure, which solves the problems in the prior art where oil easily remains in the inner cavity of the casing, causing odors to be emitted inside the casing, bacteria to grow, and oil stains to drip onto the stove after the smoke guide plate is opened, affecting the user experience and the lifespan of the equipment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This application provides a range hood with an oil-guiding structure, comprising:

[0008] A housing having a smoke inlet;

[0009] Side plates are disposed within the housing and used for mounting the fan;

[0010] A smoke guide plate is movably connected to the housing and is used to close or open the smoke inlet. The housing and the smoke guide plate enclose a smoke collection chamber that communicates with the smoke inlet.

[0011] An oil cup is disposed on the lower side of the housing and communicates with the smoke collection chamber;

[0012] The smoke collection chamber is provided with multiple oil guides inside its cavity wall. The surfaces of the multiple guides form an oil guiding path to guide the oil adhering in the smoke collection chamber to the oil cup.

[0013] Optionally, the oil guide includes a first oil guide slope disposed on the inner top wall of the smoke collection chamber, the first oil guide slope and the rear side of the smoke collection chamber forming a first oil guide path to guide the oil into the oil cup.

[0014] Optionally, a conduit is provided inside the housing, and an oil guide plate is provided on the outside of the conduit, which is connected to the rear side of the smoke collection chamber. The oil guide plate is used to guide the oil to the first oil guide path.

[0015] Optionally, the range hood with an oil-guiding structure also includes:

[0016] The front cover is disposed opposite to the rear side of the smoke collection chamber. The smoke inlet is opened on the front cover. The oil guiding component also includes a second oil guiding slope disposed on the inner side of the front cover and a third oil guiding slope disposed on the inner side of the smoke guiding plate and connected to the second oil guiding slope. The second oil guiding slope and the third oil guiding slope form a second oil guiding path to guide the oil into the oil cup.

[0017] Optionally, a connecting strip is provided on the upper side of the front cover, and the outer side of the connecting strip abuts against the inner side of the smoke guide plate. The oil guide also includes a fourth oil guide slope disposed on the inner side of the connecting strip and connected to the third oil guide slope.

[0018] Optionally, the connecting strip is made of an elastic material.

[0019] Optionally, the connecting strip abuts against the inner side of the smoke guide plate.

[0020] Optionally, the connecting strip abuts against one side of the smoke guide plate in an arc shape.

[0021] Optionally, the smoke guide plate is provided with an installation shell on its inner side, and the oil guide component further includes a fifth oil guide slope disposed on the outer bottom wall of the installation shell and connected to the side of the installation shell. The side of the installation shell and the fifth oil guide slope form a third oil guide path to guide the oil into the oil cup.

[0022] Optionally, the edges of the smoking openings are all curved.

[0023] The beneficial effects of this utility model are:

[0024] By creating an oil-guiding path within the smoke collection chamber, when the fan draws fumes into the chamber through the smoke inlet, the oil molecules in the fumes condense and adhere to the inner wall of the chamber upon contact with it. Guided by the oil-guiding path, the oil flows along the path into the oil cup, reducing the possibility of oil accumulation within the chamber. Therefore, during use, the oil generated on the walls of the smoke collection chamber gradually flows along the oil-guiding path into the oil cup for collection. Users only need to clean the oil cup regularly, effectively reducing the possibility of oil residue inside the smoke collection chamber. This not only reduces the likelihood of odors or bacterial growth inside the casing but also allows oil adhering to the smoke guide plate to flow into the oil cup during the opening and closing of the guide plate, reducing the possibility of oil softening at high temperatures and dripping onto the kitchen stove. This effectively improves the user experience and extends the lifespan of the equipment. Attached Figure Description

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 5 As shown, this utility model provides a range hood with an oil guiding structure.

[0037] The range hood with an oil-guiding structure includes a housing 1, a smoke guide plate 3, and an oil cup 4. The housing 1 has a smoke inlet 11; the smoke guide plate 3 is movably connected to the housing 1 and is used to close or open the smoke inlet 11. The housing 1 and the smoke guide plate 3 enclose a smoke collection chamber 12 that communicates with the smoke inlet 11. Multiple oil-guiding components 6 are arranged inside the wall of the smoke collection chamber 12, forming an oil-guiding path 7 to guide the oil adhering in the smoke collection chamber 12 to the oil cup 4. A side plate 2 is provided on the side of the housing 1 opposite the smoke guide plate 3, and the side plate 2 is used to install a fan 5.

[0038] By forming an oil guiding path 7 in the smoke collection chamber 12, when the fan 5 draws the oil fumes into the smoke collection chamber 12 through the smoke inlet 11, the oil fumes come into contact with the cavity wall of the smoke collection chamber 12, and the oil molecules in the oil fumes will condense and adhere to the inner wall of the smoke collection chamber 12. Under the guidance of the oil guiding path, the oil will flow along the oil guiding path 7 into the oil cup 4, so as to reduce the possibility of oil accumulation in the smoke collection chamber 12. Therefore, when the range hood with the oil guiding structure is in use, the oil produced on the cavity wall of the smoke collection chamber 12 can gradually flow along the oil guiding path 7 into the oil cup 4 and be collected. Users only need to clean the oil cup 4 in time, thereby effectively reducing the possibility of oil residue inside the smoke collection chamber 12. This not only reduces the possibility of odor or bacteria growth inside the casing 1, but also allows the oil stains attached to the smoke guiding plate 3 to flow into the oil cup 4 along the oil guiding path during the opening or closing of the smoke guiding plate 3. This reduces the possibility of oil stains softening at high temperatures and dripping onto the kitchen stove, thereby effectively improving the user experience and helping to extend the service life of the equipment.

[0039] Optionally, the oil guide 6 includes a first oil guide slope 61 disposed on the inner top wall of the smoke collection chamber 12. The first oil guide slope 61 and the rear side of the smoke collection chamber 12 form a first oil guide path 71 to guide the oil into the oil cup 4.

[0040] Specifically, the inner top wall of the smoke collection chamber 12 is lower on the side near the side plate 2 than on the other side, thus forming a first oil guiding slope 61 on the inner top wall. The inner side of the side plate 2 serves as the rear side of the smoke collection chamber 12 and extends vertically. Its upper side is connected to the first oil guiding slope 61, and its lower side extends towards the direction close to the oil cup 4. The oil adhering to the inner top wall of the smoke collection chamber 12 can gradually flow into the oil cup 4 along the first oil guiding path 71 formed by the first guiding slope and the side of the side plate 2.

[0041] Optionally, a conduit 8 is provided inside the housing 1, and an oil guide plate 81 connected to the rear side of the smoke collection chamber 12 is provided on the outside of the conduit 8. The oil guide plate 81 is used to guide the oil to the first oil guide path 71.

[0042] Specifically, the conduit 8 is cylindrical and fixed inside the smoke collection chamber 12. The conduit 8 has a cavity inside to accommodate cables and other structures. A strip-shaped oil guide plate 81 is provided on the outer wall of the conduit 8. The side wall of the oil guide plate 81 is connected to the side of the side plate 2, and the oil guide plate 81 can be tilted toward the side plate 2 to guide the oil to the first guide path, thereby reducing the possibility of oil accumulating on the outer surface of the conduit 8 and further reducing the possibility of oil residue in the smoke collection chamber 12.

[0043] Optionally, the range hood with the oil guiding structure also includes a front cover 13. The front cover 13 is disposed opposite to the rear side of the smoke collection chamber 12, and the smoke inlet 11 is opened in the front cover 13. The oil guiding component 6 also includes a second oil guiding slope 62 disposed inside the front cover 13 and a third oil guiding slope 63 disposed inside the smoke guide plate 3 and connected to the second oil guiding slope 62. The second oil guiding slope 62 and the third oil guiding slope 63 form a second oil guiding path 72 to guide the oil to the oil cup 4.

[0044] Specifically, the smoke guide plate 3 includes a connecting cover 31 and a closing cover 32. The upper side of the connecting cover 31 is hinged to the upper side of the housing 1, and the lower side of the connecting cover 31 is hinged to the closing cover 32. The lower side of the front cover 13 is hinged to the lower side of the housing 1, and the front cover 13 is correspondingly connected to the connecting cover 31. A through hole is opened in the middle of the front cover 13 as a smoke inlet 11. In order to reduce the possibility of oil accumulation at the smoke inlet 11, the edges of the smoke inlet 11 are all arc-shaped to guide the residual oil to the second oil guiding slope 62.

[0045] When it is necessary to close the smoke inlet 11, both the connecting cover 31 and the closing cover 32 rotate toward the fan 5 under the action of the drive mechanism, thereby placing the smoke guide plate 3 and the front cover 13 inside the housing 1 and closing the smoke inlet 11. When it is necessary to extract oil fumes, the smoke guide plate 3 is opened. At this time, both the connecting cover 31 and the closing cover 32 rotate away from the fan 5 and drive the front cover 13 to rotate outward, so that the smoke inlet 11 can face the oil fumes. The closing cover 32 can also effectively restrict the flow of oil fumes and improve the extraction effect.

[0046] The inner wall of the connecting cover 31 serves as the third oil guiding slope 63, while the inner side wall of the front cover 13 serves as the second oil guiding slope 62. The upper side of the connecting cover 31 can be directly connected to the connecting cover 31, so that the second oil guiding slope 62 and the third oil guiding slope 63 are connected. Alternatively, an elastic connection structure can be provided between the front cover 13 and the connecting cover 31, which can also achieve the connection between the second oil guiding slope 62 and the third oil guiding slope 63. When oil accumulates on the third oil guiding slope 63, the oil can flow along the second oil guiding path 72 through the third oil guiding slope 63 and the second oil guiding slope 62 into the oil cup 4.

[0047] Optionally, a connecting strip 9 is provided on the upper side of the front cover 13, and the outer side of the connecting strip 9 abuts against the inner side of the smoke guide plate 3. The oil guide 6 also includes a fourth oil guide slope 64 provided on the inner side of the connecting strip 9 and connected to the third oil guide slope 63.

[0048] Specifically, an installation groove is formed on the inner side wall of the front cover 13, and a fixing strip 91 is inserted into the installation groove. Adhesive can be filled into the installation groove to fix the fixing strip 91 in the installation groove. The fixing strip 91 can also be fixed by welding or bolt connection. The lower side of the connecting strip 9 is embedded in the fixing strip 91 to form a snap-fit ​​fixation. Its upper outer side is attached to the inner wall of the connecting cover 31, and its inner side forms a fourth oil guiding slope 64. The lower side of the fourth oil guiding slope 64 is adapted to the second oil guiding slope 62, and the upper side is adapted to the third oil guiding slope 63, thereby connecting the third oil guiding slope 63 and the second oil guiding slope 62 together. This ensures that there is no gap between the connecting cover 31 and the front cover 13, and the oil can flow smoothly from the third oil guiding slope 63 to the second oil guiding slope 62.

[0049] Optionally, the connecting strip 9 is made of an elastic material. The connecting strip 9 abuts against the inner side of the smoke guide plate 3. The connecting strip 9 abuts against one side of the smoke guide plate 3 in an arc shape.

[0050] Specifically, the connecting strip 9 can be made of elastic materials such as rubber to ensure that it has sufficient deformation capacity. The connecting strip 9 abuts against the smoke guide plate 3 to form an interference fit, ensuring that there is no gap between the two. The side of the connecting strip 9 near the smoke guide plate 3 is bent inward into an arc shape, so that the outer wall of the connecting strip 9 is at least arc-shaped near the smoke guide plate 3. In this way, during the opening or closing of the smoke guide plate 3, the smoke guide plate 3 can smoothly squeeze the connecting strip 9 and generate relative movement with the connecting strip 9. On the one hand, this can ensure that the connecting strip 9 remains in a tight abutment with the connecting cover 31, and on the other hand, it can reduce the possibility that the connecting strip 9 will obstruct the opening or closing of the smoke guide plate 3.

[0051] Optionally, the smoke guide plate 3 is provided with a mounting shell 33 on the inner side, and the oil guide component 6 also includes a fifth oil guide slope 65 provided on the outer bottom wall of the mounting shell 33 and connected to the side of the mounting shell 33. The side of the mounting shell 33 and the fifth oil guide slope 65 form a third oil guide path 73 to guide the oil to the oil cup 4.

[0052] Specifically, the connecting cover 31 is partially convex to form a mounting shell 33. A driving structure can be set inside the mounting shell 33 to drive the smoke guide plate 3 to move. The side of the mounting shell 33 is vertically downward and the bottom wall of the mounting shell 33 is inclined downward, thus forming a fifth oil guiding slope 65 on the outer bottom wall of the housing 1. The side of the mounting shell 33 and the fifth oil guiding slope 65 are arc transitioned to form a third oil guiding path 73. The third oil guiding path 73 can guide the oil accumulated on the outer surface of the mounting shell 33 to the oil cup 4, so as to further reduce the possibility of oil residue in the smoke collection chamber 12.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
