Extractor hood and integrated type steam generation module thereof

Abstract

The invention relates to the technical field of extractor hoods and discloses an extractor hood and an integrated type steam generation module thereof. The steam generation module comprises a closed water storage vessel, a heating body and a power plug, wherein the heating body is arranged at the bottom of the water storage vessel, and the power plug is electrically connected to the heating body.The water storage vessel is provided with a water injection opening and a steam outlet, wherein the steam outlet is used for discharging steam. A steam pipe joint is connected to the steam outlet. Onthe extractor hood, the integrated type steam generation module is movably mounted inside a side plate of the extractor hood; and the high-temperature steam can be generated through heating of the integrated type steam generation module, and the effect that self-cleaning is conducted on a vane wheel is achieved. The extractor hood and the integrated type steam generation module thereof have the beneficial effects that production and mounting are convenient to conduct; a water pump structure adopted in a previous cleaning structure is omitted; and the cost is greatly lowered, and cleaning noiseis reduced.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an integrated steam generating module and a range hood using the module. Background technique [0002] After the range hood is used frequently, a large amount of oil will accumulate in the air duct system, especially the inner wall of the motor, impeller and volute. The oil will have a great impact on the dynamic balance of the impeller, which will have a negative impact on the performance of the whole machine. Many manufacturers on the market have added the self-cleaning function. The currently known principle of steam cleaning is nothing more than pumping cold water into the heating module, heating it through the heating module to generate steam, and then transporting it to the nozzle through the pipeline, and the high-temperature water sprayed out by the nozzle High pressure steam cleans the impeller. [0003] The traditional steam self-cleaning modules all adopt the desi...

AI Technical Summary

Problems solved by technology

[0003] The traditional steam self-cleaning modules all adopt the design scheme of "water cup + water pump + heating body". This traditional solution will cause the following problems: First, the water cup and the heating body need to find a suitable position on the machine, which is not conducive to the overall The optimization and modular design of the machine structure; second, the water cup and the heating body are set separately and connected to each other through pipelines, which makes the connection of pipelines and various parts complicated, increases the risk of water leakage, and requires higher pressure for the water pump; Three, in the process of generating steam, the water pump needs to be running all the time to pump water, which will generate a lot of noise during the cleaning process
