Cooking appliance having thermal decomposition function

Abstract

The present invention relates to a cooking appliance including: a cooking chamber surrounded by a cooking chamber wall and a door; a heating means disposed in the cooking chamber for emitting heat;a combustion pipe, which is a pipe formed so as to be hollow in order to surround the heating means, and which is heated by the heating means so that radiation heat therefrom is provided to the central part of the cooking chamber; a combustion space, which is a space formed between the heating means and the combustion pipe, and in which a contaminant is thermally decomposed by heat from the heating means; a blowing fan which takes air into the cooking chamber and moves a part or the entire mass of the air that has been taken in through a connection pipe to the combustion space; the connection pipe which connects the combustion pipe with the blowing fan so that the communication of the air is possible; and an outlet through which the gases that contain water vapors in the combustion space are discharged out of the cooking appliance. According to the cooking appliance of the present invention, the heating means heats the combustion space so as to thermally decompose contaminants. Further, the radiation heat is provided to the cooking chamber through the combustion pipe so that food is heated with high energy efficiency.

Description

technical field [0001] The present invention relates to a device for pyrolytically removing odors and harmful substances that occur during cooking. In particular, it relates to a cooking device in which the heating device arranged on the upper part of the cooking box not only plays the role of pyrolyzing the volatile substances generated during cooking, but also provides radiant heat to the cooking box to heat the cooking box. Food parts come into play. Background technique [0002] When food is heated indoors using cooking equipment, pollutants are expelled from the food along with water vapor. These pollutants include toxic substances that are harmful to health, such as formaldehyde, which causes cancer. Therefore, it is necessary to prevent the diffusion of these pollutants from the cooking equipment into the room, so as to minimize the adverse effects on the users of the cooking equipment or those around them. Many households are equipped with smoke exhaust machines t...

AI Technical Summary

Problems solved by technology

However, the combustion method used in conventional cooking equipment is to take the food out of the cooking box and heat the cooking box to about 400°C, which cannot solve the problem of the diffusion of pollutants into the room during the cooking of food.
