Self-cleaning smoke exhaust ventilator

Abstract

The invention relates to a self-cleaning smoke exhaust ventilator. The self-cleaning smoke exhaust ventilator comprises an air draft hood, a cleaning pool unit, a filter net unit and a blower box unit, wherein the cleaning pool unit is arranged at the top of the air draft hood; the filter net unit is arranged in the cleaning pool unit; the blower box unit is arranged above the cleaning pool unit to be communicated with the cleaning pool unit; the cleaning pool unit comprises a box body and a cleaning pool positioned at the lower part of the box body; the filter net unit comprises a rotating barrel-shaped filter net; the barrel-shaped filter net is longitudinally arranged in the box body of the cleaning pool unit; the lower end of the barrel-shaped filter net covers an air outlet of the air draft hood, and a seal opening is formed in the upper end of the air draft hood; cleaning fluid in the cleaning pool is sprayed to the rotating barrel-shaped filter net to form a cleaning fluid curtain through a cleaning fluid spraying pipe. The self-cleaning smoke exhaust ventilator is simple and compact in structure; when the self-cleaning smoke exhaust ventilator is used, a blower works, a negative pressure area is generated in the filter net unit; when passing through the cleaning fluid curtain of the rotating barrel-shaped filter net through an air inlet of the air draft hood, oil smoke gas and the cleaning fluid form a gas-liquid mixed flow process, and the oil smoke is cleaned in time; the troublesome cleaning of a user is prevented.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood capable of automatic cleaning. Background technique [0002] In the existing range hood cleaning technology, some use the jet impeller method. Since the filter screen or filter plate of the range hood is often blocked by oil and grease, the oil will be sprayed directly on the kitchen stove when the machine is turned on for cleaning; The way of the electrode plate makes the static electricity formed by the positive and negative electrodes at a certain distance, absorb and stick the small oil droplets to the point plate under the action of static electricity, etc., but after a long time of use, there is still the problem that it is difficult to clean up after the accumulation of oil and grease etc. This not only causes trouble for users to clean up, but also provides directions for producers to strive for improvement. [0003] Therefore, the inventor of this case invented automatic cl...
