Range hood

Abstract

A range hood comprising a hood body, a ventilation fan inside a continuous pipe; a water container is on the bottom of the hood body, a removable board is on the front side of the hood body, a filter net is in between from inside of the removable board to the continuous pipe. Based on the described above; water level in the water container is above the bottom of the removable board and the filter net, when the ventilation fan is on, air is sucked in from the inlet pipe, the soot is also sucked in; the air flow rushes from water surface and flows from the bottom of the removable board and turns to the filter net, and forms a small water curtain between removable board and the filter net; the present invention achieves washing, sucking particles and dust, prevent fire hazard, water recycling and easy to maintain effect.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] This invention relates generally to a range hood and, more specifically, to a range hood that forms a water curtain between removable board and filter net, water curtain sucks oily particles and dust into water container, the present invention has washing, sucking particles and dust, prevent fire hazard, water recycling and easy to maintain effect. [0003] (b) Description of the Prior Art [0004] Heretofore, it is known that cooking can make lots of soot in kitchen, range hoods are applied to suck soot, however they might cause air pollution, the soot breathed into lung might cause lung cancer. Electronic microscope shows soot is particle, after vibration, they flow to everywhere, those un-oily carbon smoke sticks onto range hood makes house ugly. Reducing soot in kitchen, choose high blow range hood becomes people high light of choosing range hood. Most of the range hoods are connected to external pipes to outside o...

AI Technical Summary

Benefits of technology

[0008] Based on the structure described above, water level in the water container is above the bottom of the removable board and the filter net, when the ventilation fan is on, air is sucked in from the inlet pipe, the soot is also sucked in; the air flow rushes from water surface and flows from the bottom of the removable board and turns to the filter net, and forms a small water curtain between removable board and the filter net, the filter net guides water back to water container; the present invention achieves washing, sucking particles and dust, prevent fire hazard, water recycling and easy to maintain effect.

Problems solved by technology

Heretofore, it is known that cooking can make lots of soot in kitchen, range hoods are applied to suck soot, however they might cause air pollution, the soot breathed into lung might cause lung cancer.

Most of the range hoods are connected to external pipes to outside of houses without sucking oil effect, those oil accumulate inside the pipes might cause fire hazard.
