Problems solved by technology

A major disadvantage of this gas burner construction is that the flame generated by the above-mentioned kind of flame port releases a large amount of heat into the environment
Therefore, the efficiency of the gas burner is low
In addition, the heat released into the environment can have a negative effect on the appearance and longevity of components placed within close proximity, such as the color of work plates of domestic cooking appliances on which gas burners are fixed, etc.

Abstract

A gas burner (10) comprising a bowl-shaped base body (12), a burner crown (14) arranged on the base body (12) and an upper cap (16) arranged on the burner crown (14), wherein a plurality of flame ports (34) is provided to let out a gas-air mixture towards to a recipient (36) to be heated, wherein the flame ports (34) are formed in such a manner that the gas-air mixture leaves the flame ports (34) in an essentially vertical direction.

Description

technical field [0001] The invention relates to a gas burner, which comprises a bowl-shaped base body, a burner crown arranged on the base body and an upper cover arranged on the burner crown, wherein a plurality of flame ports are arranged to release gas to a container to be heated air mixture. Background technique [0002] A gas burner of the above-mentioned kind is known, for example, from EP-A-1512909. This gas burner is mainly formed by a bowl-shaped base body, a toothed burner crown and an upper cover arranged on the base body. The bowl-shaped base body is connected to the injector through which the gas is supplied. The burner crown is provided with a plurality of flame ports on its circumference so that the gas-air mixture is released in a radial direction and substantially parallel to the bottom of the vessel to be heated. The upper cover closes the top of the burner and together with the burner crown defines the flame ports. The size and number of flame ports ca...
