Anti-oil accumulation volute device and range hood applying same

Abstract

The invention relates to an anti-oil accumulation volute devicecomprising a volute, a heating film, and a steam degreasing unit. The heating film is affixed on the outer side of the annular wall of the volute, and an oil discharge outlet is formed at the bottom of the volute; the steam degreasing unit comprises a water storage box, a steam generator connected with the water storage box, a steam pipe connected with the steam generator, and a jet tube connected to an outlet of the steam pipe; the whole jet tube is in an annular shape and arranged at the position, adjacent to the inner side of the annular wall of the volute, of the volute; and multiple spray holes are formed on the jet tube. According to the anti-oil accumulation volute device, self-cleaning of volute greasy dirt can be realized by the cooperation of the heating film and the steam degreasing unit, the heating film can enhance the flowability of the greasy dirt, the greasy dirt can be quickly discharged out of the volute in cooperation with the flushing of steam, and meanwhile the jet tube is in an annular shape, so that a flushing area for the volute is large and the cleaning effect of the greasy dirt is good. The anti-oil accumulation volute device is low in energy consumption and high in cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an oil accumulation prevention volute device and a range hood applied with the device. Background technique [0002] The range hood will accumulate a lot of grease during long-term use, and the inner cavity of the volute will accumulate a lot of oil fume, which is not easy to clean directly. After long-term use, a layer of grease will accumulate in the inner cavity of the volute, resulting in changes in the air duct of the volute , Increase the noise of the range hood and affect the normal working performance of the range hood. [0003] Authorized announcement number is CN204438265U (application number is 201420673285.0) Chinese utility model patent "An Electric Heating Range Hood with Waterproof Oil Draining Function", in which the disclosed scheme is to stick a heating film on the volute, and through the heating film to The volute conducts heat transfer, thereby heating an...

Problems solved by technology

In this scheme, after the oil is heated, the degreasing effect is achieved by relying on the flow of the oil itself. Due to the poor fluidity of the oil, to ensure a good degreasing effect, the heating film needs to work for a long time, and the energy consumption is high.

[0004] Authorized announcement number is CN203501276U (application number is 201320598718.6) Chinese utility model patent "A Side Suction Steam Cleaning Range Hood", in which the disclosed scheme is to clean the oil stains by setting a steam generator, but the structure is through the end of the steam pipe Extending between the wind wheel and the volute, the steam nozzle installed at the end of the steam pipe faces the fixed position of the volute, and then cleans the oil stains, so the degreasing area is small and the degreasing effect is poor. In the case of cleaning the oil stains, the oil stains cannot be quickly washed and discharged, and the work efficiency is low
