[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from stove combustion and the fumes harmful to the human body generated during the cooking process and discharge them outdoors. At the same time, it condenses and collects the fumes to reduce pollution, purify the air, and has anti-toxic and explosion-proof safety protection functions.

[0003] In order to filter out some grease and solid particles in the oil smoke and avoid damage to the motor and mechanical parts inside the range hood, a double-layer oil net is usually provided at the oil extraction port of the range hood. When the oil smoke passes through the double-layer oil net, some grease and solid particles will adhere to its surface. After long-term use, the mixture of grease and solid particles will solidify on the surface of the oil net. The existing double-layer oil net is usually fixedly connected to the range hood by a screw. When cleaning is required, the double-layer oil net can be removed by removing the screw to rinse it. The double-layer oil net includes an outer oil net and an inner oil net. The inner oil net is usually fixedly connected to the outer oil net. Therefore, the stubborn oil stains between the inner oil net and the outer oil net cannot be cleaned, which will also affect the oil extraction efficiency of the range hood.

DETAILED DESCRIPTION

[0027] The following will be combined with the attached embodiment of the utility model Figure 1-11 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example:

[0029] like Figures 1 to 11As shown, the utility model discloses a double-layer oil net 5 for a range hood which is easy to clean and a range hood, comprising a range hood body 1, an air duct 2 being provided on the range hood body 1, a suction chamber 3 being provided at the lower end of the air duct 2, the suction chamber 3 being fixedly connected with a mounting inclined frame 4 at the lower end of the air duct 2, a double-layer oil net 5 being fixedly connected with the mounting inclined frame 4, the double-layer oil net 5 comprising an outer oil net 6 and an inner oil net 7, a scraper assembly for scraping off oil stains on the double-layer oil net 5 being cooperatively arranged between the outer oil net 6 and the inner oil net 7, and an oil collecting assembly for collecting oil stains being detachably arranged at the lowest part of the double-layer oil net 5.

[0030] The scraper assembly includes a trapezoidal scraper 8, which is arranged between the outer oil net 6 and the inner oil net 7, and the lower end of the outer oil net 6 is symmetrically provided with a movable groove 61, and the lower end surface of the trapezoidal scraper 8 is symmetrically provided with a drag rod 81. When cleaning the double-layer oil net 5, the trapezoidal scraper 8 can be driven to move by dragging the drag rod 81, so as to scrape off the oil attached to the surface of the outer oil net 6 and the inner oil net 7. The cross section of the trapezoidal scraper 8 in this embodiment is a right-angled trapezoid, and its inclined surface faces the lowest point of the double-layer oil net 5. When the trapezoidal scraper 8 is pushed to move from high to low, the oil attached to the inner oil net 7 will slide down the trapezoidal scraper 8 to the outer oil net 6 after being scraped, and will be sent into the oil collecting assembly by the cleaning scraper together with the oil scraped off from the outer oil net 6;

[0031] Furthermore, in order to further increase the cleaning ability of the trapezoidal scraper 8, a plurality of cleaning lines 82 are provided on the upper and lower end surfaces of the trapezoidal scraper 8, thereby increasing the friction between the cleaning scraper and the double-layer oil net 5, so as to facilitate the removal of stubborn oil stains on the double-layer oil net 5.

[0032] Furthermore, the oil collecting assembly includes a connecting frame 9 and an oil collecting box 10, and the oil collecting box 10 is detachably connected to the lower end of the connecting frame 9. The specific connection method of the oil collecting assembly is as follows: the upper end of the outer oil net 6 is fixedly connected with a connecting column 62, and the upper end of the connecting frame 9 is fixedly connected with a corresponding sleeve rod 91, and the connecting frame 9 is hung on the connecting column 62 through the sleeve rod 91. The outer side of the side wall of the connecting column 62 is provided with an external thread 63, and the external thread 63 is threadedly connected with a fixing nut 64; the outer oil net 6 is at the lowest An oil leakage hole 65 is opened at the connecting frame 9, and an oil inlet 92 is opened at the upper end of the connecting frame 9, and the oil inlet 92 is located directly below the oil leakage hole 65. The connecting frame 9 is fixedly connected with an oil receiving plate 93 on the side of the oil inlet 92 facing the outer oil net 6. When the oil on the double-layer oil net 5 is scraped off, it enters the oil collecting box 10 through the oil inlet 92. Some liquid grease is easy to drip onto the stove during the falling process. The oil receiving plate 93, as an extension of the oil inlet 92, can catch the dripping liquid grease to prevent it from contaminating the stove.

[0033] Furthermore, the specific connection method between the connecting frame 9 and the oil collecting box 10 is: a rubber ring 94 is fixedly connected to the outer wall of the lower end of the connecting frame 9 of the connecting frame 9, and the rubber ring 94 is abutted against the inner wall of the oil collecting box 10. The connecting frame 9 is provided with at least two abutting grooves 95 above the rubber ring 94, and a corresponding buckle 101 is integrally formed on the inner wall of the oil collecting box 10, and the buckle 101 is abutted in the abutting groove 95. Through the above structure, the friction resistance between the outer wall of the connecting frame 9 and the inner wall of the oil collecting box 10 is increased. Relying on the friction resistance between the inner wall of the oil collecting box 10 and the outer wall of the connecting frame 9, the oil collecting box 10 is fixed to the lower end of the connecting frame 9. When the oil collecting box 10 needs to be thoroughly cleaned, the oil collecting box 10 can be removed by simply holding the oil collecting box 10 and pulling it downward with force.

[0034] It should be noted here that, since a large amount of oil smoke generated by cooking is discharged outdoors through the air duct 2, only some grease and solid particles are attached to the double-layer oil net 5, which are relatively light in weight. Therefore, there is no possibility that the oil collecting box 10 will fall off from the connecting frame 9 due to excessive oil storage.

[0035] In addition, a placement groove 102 with an opening facing upward is provided on the rear side wall of the oil collecting box 10, a baffle 103 is inserted in the placement groove 102, a through hole 104 is radially penetrated at the lower end of the rear side wall, and a sealing layer 105 is fixedly connected to the outer side of the baffle 103, thereby ensuring that oil will not leak through the gap between the baffle 103 and the placement groove 102. If the oil collecting box 10 only needs to be simply cleaned, it is only necessary to pull out the baffle 103 and let the oil flow out of the oil collecting box 10 along the slope.

[0036] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
