High-efficiency self-cleaning type range hood and manufacturing method thereof

Abstract

The invention discloses a high-efficiency self-cleaning type range hood. The high-efficiency self-cleaning type range hood comprises a machine shell and a smoke exhaust system, wherein the smoke exhaust system comprises a lateral suction device and a top air suction device, the lateral suction device comprises a first cover plate, a first impeller assembly, a first lateral suction shell and a impurity removal device, the impurity removal device comprises a filter box, an air flue assembly is arranged above the shell, and the oily fume absorber is arranged in the air flue. The manufacturing method of the high-efficiency self-cleaning type range hood comprises the following steps that, 1. preparation and installation of the smoke exhaust system are conducted; 2, manufacturing of the air flueassembly is conducted; and 3, manufacturing of the shell and mounting of the whole are conducted. According to the high-efficiency self-cleaning type range hood and the manufacturing method thereof,use is convenient, manufacturing cost is low, environment-friendly and ecological purposes are realized, smoke can be absorbed through multiple angles, the oily fume absorption rate of the range hoodis improved; and the interior of the air flue of the range hood is subjected to design and transformation, so that the air flue has oily fume purification effect, the purification rate of the oily fume gas can reach 90%-98%, and the purification cost of the oily fume is low.

Description

technical field [0001] The invention relates to the technical field of oil fume purification, in particular to a high-efficiency self-cleaning range hood and a manufacturing method thereof. Background technique [0002] my country is a big cooking country with various cooking methods. Kitchen fumes can cause harm to the human respiratory system. According to data, more than 60% of non-smoking women who induce lung cancer are exposed to kitchen fumes for a long time, which is very harmful to health. According to statistics, about 1.6 million people die from respiratory diseases in the world every year, and soot-type fluorosis and arsenic poisoning have become endemic diseases in some areas of China. Experts pointed out that in addition to correctly controlling the oil temperature and cooking time, choosing the correct range hood can reduce the harm of kitchen fumes to the human body. [0003] Existing range hoods generally use an oil filter or centrifugal separation, so that ...

Problems solved by technology

A typical range hood is generally installed around the gas stove. When working, it can effectively shield the waste gas generated around the gas stove, the oil fume generated during the cooking process, and the dry heat in the kitchen. , can not achieve 360° air intake, the range hood can only ensure that the smoke closest to the central area of ​​the smoke inlet enters in all directions, and the smoke that is far away can easily escape, and usually it is placed directly aside without further treatment of the kitchen fume. Although the amount of smoke emitted by the home kitchen is not large, it will also pollute the air.
