Low cost burner

Abstract

A gas burner comprising a section for mixing combustible gas with air; a cover lid closing the mixing section; and a crenellated wall comprising first segments with a first thickness and one or more second segments with a second thickness greater than the first thickness, the second segment allows the cover lid to be sitting and placed over the wall, and main portholes which are constant for a determined length of said main portholes from an inside towards an outside of the crenellated wall, and near the outside of the crenellated wall, the height of the porthole is decreased by virtue of an α angle; one or more secondary portholes with a size smaller than the main portholes, wherein the at least one secondary porthole has a change in direction in such a way, that the height of the at least one secondary porthole decreases from the inside towards the outside of the crenellated wall according to a β angle until the height of the porthole achieves a constant height near the outside of the wall; and two or more tertiary portholes per each first and second segment with a half cane shape, the diameter of each half cane being equal to the width and depth of said tertiary porthole, wherein said tertiary portholes are of lesser size than the at least one secondary porthole.

Description

FIELD OF THE INVENTION[0001]Present invention lies in the field of gas burners, particularly burners used in household appliance equipment, such as stoves, kitchens or cooking surfaces.BACKGROUND OF THE INVENTION[0002]A great variety of burners can be found in the marketplace for use in household appliances or industrial ones based on an atmospheric Bunsen burner; initially, the main objective of these was to provide a flame which would turn on over the utensils to be heated; achieving this without considering efficiency aspects of the combustibles used in the heating or ecologic oriented aspects, heating speed, the shape of the cooking utensils, among others, through time the design of the burners has evolved towards the solving of the above mentioned aspects.[0003]Currently, a considerable amount of burners for use in household appliances exists in the marketplace; initially, the main objective of these was to provide a flame which would turn on over the utensils to be heated with...

AI Technical Summary

Benefits of technology

The invention is about a burner for heating air-combustible mixtures. The burner has a Venturi tube that drags air around it and sucks it in. This air is mixed with the combustible in a pre-mixing chamber, and the mixture is then forced out of the burner through portholes. The portholes are designed to uniform the speed of the air-combustible mixture and ensure correct flame anchoring and optimal combustion. The burner also has an air ring that improves the secondary air flow towards the flame base. Overall, the invention provides a more efficient and controlled way of heating air-combustible mixtures.

Problems solved by technology

Present invention lies in the field of gas burners, particularly Bunsen burners used in household appliance equipment, such as stoves, kitchens or cooking surfaces; if there is a large variety of these burners both in the marketplace as well as in the state of the art, these are quite difficult to conceive and put into practice, given that they require extensive laboratory tests as well as advanced knowledge in the areas of combustion, fluids, heat transfer and mechanics among others; having a burner which works is an art in itself, and even more difficult is making a burner which functions in an efficient manner, and even further difficult is achieving all this at a low cost, as this implies advanced knowledge of manufacturing processes.
