Burner assembly for cooking equipments

Abstract

The present invention relates to a burner assembly for cooking equipments that has been designed to provide significant improvement in thermal efficiency of the burner and making easier the cleaning process by the user. The burner assembly comprises a base (2) upon which a spreading cover (3) rests, and wherein the coupling of the spreading cover (3) on the base (2) originates one internal chamber of expansion (4) of air-fuel mixture which is released through porticos existing under the perimeter edge of the spreading cover (3), and wherein the base (2) comprises in its internal region at least one feeding orifice (22); the spreading cover (3) comprises at least one perimeter ring (31) cooperating with the base (2) and at least one disc (32) cooperating with the perimeter ring (31) and the burner assembly (1) comprises at least one internal chamber of mixture (4) cooperating with the porticos of the spreading cover (3).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a burner assembly for cooking equipments, and more specifically to a burner provided with a spreading cover having two or more portico rings to output air-fuel mixture, which was developed to provide significant improvement in thermal efficiency and heat power of the equipment, in addition to presenting smooth geometry (both in the base and in the spreading cover) providing greater easiness of cleaning by the user, and which can also provide a simpler and more economical constructive process than similar known ones.BACKGROUND OF THE INVENTION[0002]As is well known, the burners are components of stoves that are located close to the cooking table and comprise the elements responsible for receiving the fuel from the supply source (whether it a cylinder of liquefied petroleum gas or a public network of natural gas), mix it to ambient air and release the fuel-air mixture to burn, when requested by the user.[0003]As it regards m...

AI Technical Summary

Benefits of technology

The present invention provides a burner assembly for cooking equipments that allows for a better distribution of flames under the cooking utensil, resulting in higher thermal efficiency. The burner has a large total output area of air-fuel mixture by porticos, allowing for high heat power. The manufacturing process and installation of the burner assembly is simple and not very expensive. The burner assembly has smooth geometry, both in the porticos and in the body, which makes it easy for end users to clean. In a preferred embodiment, the porticos of the spreader have an elliptical shape.

Problems solved by technology

In the current state of the art, there is often only one of flame output ring, which limits the thermal efficiency of the burner since it does not allow the distribution of the flames under the entire surface of the cooking utensil.

Note, however, that this type of burner provides a significantly complex constructive aspect of rustic appearance which requires that for each flame output ring, there is an independent mixing chamber.

This configuration shows a burner of construction and complex mounting and therefore costly that, moreover, also requires the manufacture and mounting of two individual covers of fittings at specific locations of the piece.

The document BR PI0112498 provides a construction in which a burner provided with two crowns of porticos have a single mixing chamber—but with very limited area due to various internal structures of the piece—which however still requires the use of two individual spreading covers on each flame output channel.

Moreover, we note that the construction of the piece is extremely complex incurring in difficulties in cleaning and maintenance by users.

It is noted, however, that the present state of the art lacks a burner assembly for cooking equipments that enables the generation of more than one ring of porticos of output of air-fuel mixture without, therefore, requiring the construction of several spreading covers and which, moreover, preferably has a single mixing chamber and having smooth geometry (both in the base and in the spreading cover and in the porticos) providing greater easiness of cleaning by the user.
