It is installed above the kitchen stove and can quickly remove the waste from stove combustion and the fumes that are harmful to the human body produced during cooking, and discharge them outdoors to reduce pollution, purify the air, and have anti-toxic and explosion-proof safety protection functions. The range hood needs to be cleaned regularly. Simple cleaning cannot remove the oil stains. Professional cleaning agents must be used to clean the range hood.

[0003] After long-term use of the existing range hood, a lot of oil will adhere to the fan impeller, which will increase the overall weight of the impeller and reduce the exhaust effect of the impeller. Summary of the invention

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a heating and oil removal device for an air guide ring of a range hood.

[0005] The above-mentioned technical problems of the utility model are mainly solved through the following technical solutions: a range hood air guide ring heating and oil removal device, comprising a shell, a smoke exhaust volute is arranged in the shell, the top of the smoke exhaust volute is connected to the upper end of the shell and is communicated with the outside of the shell, an air guide ring is arranged at the front and rear ends of the smoke exhaust volute, a plurality of brackets are arranged in a circular array along the center position of the front air guide ring, a drive motor is installed on the plurality of brackets, an impeller is arranged inside the smoke exhaust volute, the center of the impeller is fixedly connected to the drive shaft of the drive motor, a heating ring is sleeved on the rear air guide ring, and two groups of temperature control sensors are arranged on the heating ring.

[0006] Preferably, two brackets are provided at the front end of the smoke exhaust volute, and the smoke exhaust volute is fixedly connected to the inner cavity of the shell through the two brackets.

[0007] Preferably, the heating ring is coaxially arranged with the corresponding air guide ring, and the heating ring is fixedly connected to the smoke exhaust volute.

[0008] Preferably, a control module mounting box is provided on the top of the housing.

[0009] The utility model has the beneficial effects: by arranging a heating ring on the smoke exhaust volute, the setting of the heating ring can heat the inhaled oil and gas, and the heated oil and gas will increase its fluidity, so as to facilitate more smooth exhaust outside the range hood, and at the same time, the heated oil and gas can soften the oil stains attached to the impeller, so that the impeller can use centrifugal force to shake off the adhered oil stains, thereby avoiding the efficiency of the range hood; by arranging two temperature control sensors on the heating ring, the setting of the temperature control sensor can effectively control the temperature of the heating ring, thereby avoiding the danger caused by excessive temperature of the heating ring.

[0013] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0014] Embodiment: A range hood air guide ring heating and oil removal device, such as Figure 1-Figure 2 As shown, it includes a shell 1, in which a smoke exhaust volute 2 is provided, the top of the smoke exhaust volute 2 is connected to the upper end of the shell 1 and is communicated with the outside of the shell 1, and an air guide ring 3 is provided at the front and rear ends of the smoke exhaust volute 2, and a plurality of rack rods 4 are provided in a circular array along the center position on the front air guide ring 3, and a drive motor 5 is installed on the plurality of rack rods 4, an impeller 6 is provided inside the smoke exhaust volute 2, and the center of the impeller 6 is fixedly connected to the drive shaft of the drive motor 5, and a heating ring 7 is provided on the rear air guide ring 3, and two groups of temperature control sensors 8 are provided on the heating ring 7.

[0015] Two brackets 9 are provided at the front end of the smoke exhaust volute 2, and the smoke exhaust volute 2 is fixedly connected to the inner cavity of the shell 1 through the two brackets 9; the heating ring 7 is coaxially arranged with the corresponding air guide ring 3, and the heating ring 7 is fixedly connected to the smoke exhaust volute 2; the top of the shell 1 is provided with a control module installation box 10.

[0016] The principle of the utility model is as follows: when the range hood is working, the driving motor 5 rotates while the heating ring 7 works. At the same time, the two temperature control sensors 8 monitor the temperature of the heating ring 7. The impeller 6 rotates to generate suction to inhale the smoke. The inhaled smoke will pass through the two air guide rings 3 of the smoke exhaust volute 2 to the inside of the smoke exhaust volute 2 and then be discharged from the top. A part of the oil and gas inhaled into the smoke exhaust volute 2 will be heated by the heating ring 7, thereby increasing the temperature of the oil and gas, and the oil and gas entering from the rear side and the unheated oil and gas from the front side will be mixed and discharged.

[0017] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model.
