Firewood-, coal- or biomass-economizing stove with multiple combustion chamber, thermal insulation, cooking hob and chimney

Abstract

A “rocket” stove that has a plurality of vertical cylindrical cavities containing a combustion chamber, a fuel compartment and a chimney. The vertical cylindrical cavities are connected to a hot-gas chamber where the gases are utilized to heat a hob used in the manner of a griddle. The hob has apertures over the vertical cylindrical cavities, over which the food containers to be heated are placed. The hot-gas chamber has an opening and an exhaust pipe for evacuating the gases from the environment where the stove is used. The stove has a thermal-insulation covering placed between the interior walls thereof and the exterior in order to prevent burns. The exhaust pipe prevents intoxication by smoke inhalation, which commonly arises when cooking over an open fire.

Description

OBJECT OF THE INVENTION[0001]The present invention relates to a wood, coal or biomass burning stove, which allows to extract the produced fumes by means of a plurality of combustion chambers communicated with a hot fumes distribution chamber in combination with a chimney, avoiding the health problems associated with poisoning by fumes from cooking over an open fire, allowing the use of the stove in confined spaces. A second object of the invention is to reduce the risk of burns by means of thermal insulation between the outside of the stove housing and its internal elements, where the heat is produced. A third object of the invention is to enable the cooking of food contained in a plurality of containers simultaneously. A fourth object of the invention is to provide a surface that is heated by the fumes produced during the combustion for cooking and heating food, particularly tortillas, using this surface as a griddle, not being necessary to remove food containers from fire.BACKGROU...

AI Technical Summary

Benefits of technology

The present invention is a stove that can burn wood, coal, or biomass and extract the fumes through multiple combustion chambers and a hot fumes distribution chamber connected to a chimney. This stove reduces health risks associated with open fire cooking, allows for use in confined spaces, and provides thermal insulation to prevent burns. Additionally, the stove allows for simultaneous cooking of multiple containers and uses the fumes produced during combustion as a griddle, eliminating the need to remove food containers from fire.

Problems solved by technology

The problem with this stove is having a single burner, allowing the heating of only one container of food at a time and not having the means to harness the heat of the fumes produced by combustion.

In this case, the fumes produced during combustion are directed into the cavity, to be expelled after through the chimney, so that the cavity retains heat to maintain or raise the heat in the combustion chamber itself and has no means to harness the heat for other purposes such as providing a hot griddle.

This stove does not allow its use indoors as the interior of a home because it has no means for directing the fumes produced by the combustion.
