Benefits of technology

This patent describes a gas burner with three different-sized flame rings that can provide small or high heating power. The pipes and gas injectors are arranged next to each other in a straight line, making gas provision simple. The upper burner crown is centred on the burner and has a smaller cross-sectional area, resulting in a homogenous flame formation at the first flame ring. The upper burner crown also has a passage for a spark plug and / or thermocouple, improving ignition behavior and operational safety.

Problems solved by technology

Disadvantageously, current gas hobs do not provide the possibility to provide heat at multiple high-power, large-sized burners.
So, in case that the gas hob comprises four burners and four pieces of cookware should be heated at high-power burners, gas burners have to be used which do not have the desired power level.

Embodiment Construction

[0029]The present invention will now be described more fully with reference to the accompanying drawings, in which example embodiments are shown. However, this invention should not be construed as limited to the embodiments set forth herein. Throughout the following description similar reference numerals have been used to denote similar elements, parts, items or features, when applicable.

[0030]FIG. 1 illustrates an embodiment of a gas burner 1 in an assembled state and FIG. 2 illustrates said gas burner 1 according to an exploded view. The gas burner 1 comprises an injector holder 2. Said injector holder 2 may be adapted to be arranged below a work plate of a gas hob. In other words, the injector holder 2 may be integrated in the cooktop. The injector holder 2 comprises gas inlets 2.4, 2.5, 2.6 which are fluidly coupled with gas injectors 2.1, 2.2, 2.3.

[0031]According to an embodiment, the injector holder 2 may comprise multiple end faces. For example, the injector holder 2 may comp...

Abstract

The invention relates to a gas burner comprising: —an injection holder (2) with at least three gas injectors (2.1, 2.2, (2.3); —a burner crown assembly (3), the burner crown assembly (3) comprising at least three flame rings (FR1, FR2, FR3) with different sizes, the burner crown assembly (3) further comprising at least three chambers (CH1, CH2, CH3) and at least three pipes (3.1.1, 3.2.1, 3.3.1), each pipe (3.1.1, 3.2.1, 3.3.1) being fluidly coupled with a single chamber (CH1, CH2, CH3); wherein each gas injector (2.1, 2.2, 2.3) is associated with one of said pipes (3.1.1, 3.2.1, 3.3.1) for providing gas into said pipe (3.1.1, 3.2.1, 3.3.1), said pipe (3.1.1, 3.2.1, 3.3.1) being adapted to receive primary air in the area of the injection holder (2) and to provide a combustion mixture of gas and primary air to one of said flame rings (FR1, FR2, FR3) of the burner crown assembly (3).

Description

[0001]Generally, the present invention relates to the field of gas burners. More specifically, the present invention relates to a gas burner with multiple flame rings comprising different sizes for providing different heating power levels within a single gas burner.BACKGROUND OF THE INVENTION[0002]Gas burners are well-known in prior art. Specifically, cooking hob gas burners are known which comprise an injection holder, a burner crown and a burner cap. Said burner crown and burner cap form a combustion gas chamber providing a mixture of gas and primary air to a flame ring comprising a plurality of flame[0003]Ports.[0004]Gas hobs are known which comprise multiple gas burners of different sizes, specifically, different diameters in order to provide burners with different heating power levels.[0005]Disadvantageously, current gas hobs do not provide the possibility to provide heat at multiple high-power, large-sized burners. So, in case that the gas hob comprises four burners and four p...
