Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model can be arranged and designed in various different configurations.
[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.
[0031] Example:
[0032] like Figures 1 to 7 As shown, this embodiment provides an oil exhaust structure for a range hood, including:
[0033] The smoke hood 1 has a front side that is inclined downwards from front to back. A front panel 11 is provided at the lower end of the front side of the smoke hood 1, and an opening is provided at the upper end of the front side of the smoke hood 1.
[0034] The guide plate 2 is set at the open position and has an air inlet. An oil mesh 21 is set at the air inlet and a boss 22 protrudes inward at the back of the guide plate 2.
[0035] Oil guide plate 3 is attached to the rear wall of front panel 11. A guide groove 31 is recessed on the oil guide plate 3. The upper end of the guide groove 31 is corresponding to the guide plate 2, and the lower end of the guide groove 31 is corresponding to the bottom wall of smoke hood 1.
[0036] Oil cup 4 has an oil outlet on the bottom wall of the smoke hood 1. The oil cup 4 is located at the lower end of the smoke hood 1 and is positioned corresponding to the oil outlet.
[0037] In this embodiment, a hollow smoke collection chamber is defined within the smoke collection hood 1. A front panel 11, arranged from front to back and inclined downwards, is provided at the lower end of the smoke collection hood 1. An opening is provided at the upper end of the front panel 11. A guide plate 2 is provided at the opening of the smoke collection hood 1. An air inlet is provided on the guide plate 2. An oil mesh 21 is provided at the air inlet. A boss 22 is provided on the back of the guide plate 2, so that the grease flows downwards along the edge of the boss 22 to guide the grease. An oil guide plate 3 is attached to the rear wall of the front panel 11. A guide groove 31 is recessed on the rear wall of the oil guide plate 3. The upper end of the guide groove 31 is correspondingly set with the guide plate 2 to guide the grease discharged from the guide plate 2. Thus, the grease on the oil guide plate 3 is collected on the bottom wall of the fume hood 1 through the guide groove 31. The grease on the bottom wall of the fume hood 1 flows to the oil cup 4 after passing through the oil outlet. In this way, the oil path is divided into several routes for collection, and finally all the grease can be collected into the oil cup 4. Its structure is simple and can effectively solve the problem of difficult collection of oil stains inside and outside the range hood, thereby further improving the user experience.
[0038] Furthermore, it also includes a housing 5 and a diversion plate 6. The lower end of the housing 5 is connected to the upper end of the smoke collection hood 1. One end of the diversion plate 6 is connected to the front wall of the housing 5, and the other end is set from front to back and inclined upwards to connect to the top wall of the housing 5.
[0039] Preferably, it also includes an oil-absorbing component, with a vent 61 provided on the bottom wall of the drain plate 6, and the oil-absorbing component covering the vent 61.
[0040] Specifically, the tilt angle of the drainage plate 6 is 6° to 60°.
[0041] More preferably, the cross-section of the boss 22 is rectangular, and the upper end wall of the boss 22 is correspondingly set to the lower end of the front side wall of the housing 5.
[0042] Preferably, a groove is provided at the lower end of the guide plate 2 to form an oil drain hole 23. The oil drain hole 23 is connected to the front wall of the boss 22 to guide the grease on the front wall of the guide plate 2. The upper end of the oil guide plate 3 overlaps the guide plate 2.
[0043] Furthermore, the height of the upper wall of the oil guide plate 3 is higher than the height of the lower wall of the flow guide plate 2.
[0044] Specifically, a guide edge 24 is folded inward at the lower edge of the guide plate 2, and multiple oil drain ports 25 are spaced apart on the guide edge 24.
[0045] Preferably, the guide grooves 31 are located on the left and right sides of the rear wall of the oil guide plate 3, and the guide grooves 31 are provided with a baffle 32 at a position away from the middle of the oil guide plate 3 to prevent the grease on the guide grooves 31 from flowing to the sides of the oil guide plate 3.
[0046] Furthermore, the height of the upper wall of the flange 32 is higher than the height of the oil drain port 25.
[0047] Specifically, there are protruding edges 26 that bend inward on the left and right sides of the rear wall of the deflector 2.
[0048] In this embodiment, a fan is installed inside the housing 5. The lower end of the housing 5 is connected to the upper end of the fume hood 1. The front end of the diversion plate 6 is connected to the front wall of the housing 5, and the other end is inclined upwards from front to back and connected to the top wall of the housing 5. This allows the diversion plate 6 to guide the grease on the top plate of the housing 5. More preferably, a vent 61 is provided on the bottom wall of the diversion plate 6, and an oil-absorbing component is covered on the vent 61. This prevents the grease on the top plate of the housing 5 from dripping directly onto the stove through the air inlet. In addition, the oil-absorbing component is preferably made of oil-absorbing cotton.
[0049] In this embodiment, since a protrusion 22 is provided on the back of the guide plate 2 to guide the grease, and the upper end of the guide plate 2 is correspondingly provided with the front wall of the housing 5, the grease on the guide plate 6 and the front wall of the housing 5 flows from top to bottom onto the guide plate 2, and is guided by the guide plate 2. Specifically, oil drain holes 23 and oil drain ports 25 are respectively provided on the front and rear side walls at the lower end of the guide plate 2. In this way, the grease on the front wall of the guide plate 2 can be guided through the oil drain holes 23, and the grease on the rear wall of the guide plate 2 can be guided through the oil drain ports 25. Then, the grease flows onto the oil guide plate 3 through the action of the guide plate 2. More preferably, protruding edges 26 are provided on the left and right sides of the rear wall of the guide plate 2 to further guide the flow path of the grease on the guide plate 2.
[0050] In this embodiment, an overlapping edge is provided at the upper end of the rear wall of the oil guide plate 3, and a mating part is provided on the guide plate 2. The overlapping edge and the mating part are connected to each other so that the upper end of the oil guide plate 3 overlaps with the lower end of the guide plate 2, and the height of the upper wall of the oil guide plate 3 is higher than the height of the lower wall of the guide plate 2. This allows the oil guide plate 3 to completely cover the oil drain hole 23 on the guide plate 2. At the same time, the lower end of the oil guide plate 3 is inserted into the bottom of the smoke collection chamber. In this way, the oil guide plate 3 prevents the user from directly seeing the grease on the oil drain hole 23, thereby further improving the user experience. More preferably, baffles 32 are provided on the left and right sides of the rear wall of the oil guide plate 3, which can prevent the collected oil from flowing out in the left and right directions and causing water leakage. The height of the upper wall of the baffle 32 is higher than the height of the oil drain 25, thereby better guiding the grease discharged through the oil drain 25.
[0051] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
