Hearth plate of totally-closed air curtain range hood

Abstract

The invention relates to range hood cookers, in particular to a hearth plate of a totally-closed air curtain range hood. The four sides of the hearth plate are provided with angle-adjustable strip-shaped air outlets; and by means of the hearth plate of the totally-closed air curtain range hood, a totally-closed tapered air curtain can be formed, cooking fumes can be totally closed in the tapered air curtain, and the cooling fumes are conveyed to a suction port of a range hood along with the tapered air curtain and discharged out of a kitchen completely through the range hood. The hearth plateof the totally-closed air curtain range hood comprises a hearth plate body, a draught fan, a noise elimination plenum chamber, angle-adjustable strip-shaped air outlets, the range hood, the totally-closed tapered air curtain, an air-input grille, an airflow-stabilizing grille and a steel wire safety net. The hearth plate of the totally-closed air curtain range hood is characterized in that angle-adjustable strip-shaped air outlets are formed in the hearth plate body; air enters through the air-input grille and is conveyed by utilization of the draught fan; and then the air passes through the airflow-stabilizing grille, enters the noise elimination plenum chamber and is discharged from the angle-adjustable strip-shaped air outlets, and the totally-closed tapered air curtain is formed. The angle-adjustable strip-shaped air outlets are provided with corresponding air output angles, and a beveled air curtain is formed by the air discharged. A closed rectangular pyramid is formed by air curtains on four sides and the range hood; the cooling fumes are discharged out of the kitchen completely through the range hood; and pollution of the kitchen by the cooling fumes and damage to human bodies by the cooling fumes are completely isolated.

Description

1. Technical field [0001] The present invention relates to range hoods, in particular to a four-sided strip-shaped air outlet with adjustable angles, which can form a fully enclosed conical air curtain, and can completely seal oil fume in the conical air curtain, and send it to the range hood along with the conical air curtain. Suction vents and exhaust the kitchen completely through the hood. 2. Background technology [0002] Chinese cooking methods mostly use frying, frying, cooking, frying, etc., which will generate a lot of oil fume in the kitchen. The spread of oil fume will make the whole kitchen full of oil stains, which will bring many harms to the family: [0003] For the family, the kitchen is the most serious air pollution. Experts believe that the oil fume condensate under high temperature has strong carcinogenic and mutagenic effects. Oil fumes contain about 300 kinds of harmful substances, DNP (nitro polycyclic aromatic essence), etc., which contain lung carci...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the above-mentioned problems of fumes escaping in the kitchen and traditional range hoods not being clean, a bar-shaped air outlet with adjustable angles on four sides can form a fully enclosed conical air curtain, and can completely seal the fumes in the cone. In the air curtain, it is sent to the suction port of the range hood with the conical air curtain and completely exhausted from the kitchen through the hood
