Problems solved by technology

In this way, grease will stick and accumulate on the paths through which the grease passes, such as filter screens, air ducts and impellers, and in severe cases, the filter screen will be blocked.
The accumulation of grease inside the range hood not only affects the working efficiency of the range hood, but also the grease accumulated on the fan blades will cause the dynamic balance to fail, causing the range hood to vibrate, reduce performance, and increase noise
Therefore, the range hood needs to be disassembled and cleaned frequently, and the disassembly and cleaning of the range hood is a time-consuming and laborious matter.

Abstract

The invention relates to a range hood capable of purifying, mainly comprising a smoke detector, a high-pressure carbonizing net arranged in an air flue, a high-temperature carbonizing net, an atomizing device, a dust filtering net and a fan, wherein all the parts are controlled through a control chip; and the air flue is further and internally provided with a water discharging opening communicated with the outside. Compared with the prior art, the invention provides an automatically-operated range hood capable of purifying, which can carbonize lampblack entering the air flue, and discharges the lampblack after spraying and washing, so that the range hood capable of purifying has a good purifying effect, avoids the deposition of the lampblack in the air flue, completely realizes the washing-free range hood, has good purifying and air exhausting effects, and is automatic and energy-saving.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood purification machine. Background technique [0002] The range hood is an essential kitchen appliance in modern families. Existing range hoods usually include a fan system, an oil filtering device, a casing and a suspension device; the fan system usually includes a motor and an impeller, and the oil filtering device mainly includes a filter screen and an oil box. The working process of the range hood of this type of structure can be attributed to several steps such as negative pressure, suction through the impeller, separation, and discharge. The specific working process is: the motor runs to drive the coaxially connected impeller to rotate, and the rotation stirs to generate a rapid upward airflow. The airflow forms a vortex negative pressure area near the air inlet, which makes the oil fume rise rapidly. When the oil fume flows to the filter screen, rotational fri...
