Description

BURNER CAP FOR USE IN A GAS BURNER ASSEMBLY
The present invention relates to a gas cooking appliance. The present invention particularly relates to the gas burner assembly of the gas cooking appliance. The present invention more particularly relates to the burner cap of the gas burner assembly.
Gas cooking appliances which use flammable gases such as natural gas or liquefied petroleum gas are commonly known. A gas cooking appliance generally comprises a cooktop and at least one gas burner assembly which is built into the cooktop. Fig. 1 shows a prior art gas burner assembly (2´). The gas burner assembly (2´) comprises a burner head (3´) which has a plurality of circumferentially arranged openings (4´) for emitting flames, a burner base (15´) which supports and supplies the burner head (3´) with the gas/air mixture and a burner cap (1´) which is placed onto a seat (5´) of the burner head (3)´. The burner cap (1´) comprises a bottom surface (7´) which sustains burning of the gas/air mixture and spreads the flames towards the openings (4´) and a top surface (6´) which partly conceals the burner head (3´). The gas burner assembly (2´) also comprises an ignition spark plug which is utilized to ignite the gas/air mixture which flows to the outside through the openings (4´).
A proper installation of the gas burner assembly (2´) is of utmost importance. Particularly in a high capacity gas burner assembly (2´), when the burner cap (1´) is slightly dislodged, the gas begins to rapidly accumulate in the vicinity of the openings (4´) and causes a violent explosion when it is eventually ignited. Such an explosion poses a risk to the safety and health of the user. Therefore, it is customary to produce the burner head (3´) and the burner cap (1´) from comparatively heavy and thick materials which prevent misalignment and dislodging when the appliance is moved or hit by the user.
The massive burner cap (1´) is generally manufactured through cold/warm forging in which a die is used to shape the work piece. The provision of a properly machined die that is sufficiently strong to withstand the compressive forces during the production of the heavy and thick burner cap (1´) is comparatively expensive. Therefore, a drawback of the prior art burner cap (1´) is that its overall production costs are comparatively high. Another drawback is that during the forging process, the die and/or the burner cap (1´) occasionally breaks. Another drawback is that due to the small irregularities in the die surface, the curved portions of the burner cap (1´) cannot be evenly obtained. Another drawback is that the enameling process of the burner cap (1´) becomes difficult due its comparatively high mass. Another drawback is that the thermal efficiency of the gas cooking appliance drops with an increasing mass of the burner cap (1´).
An objective of the present invention is to provide an improved burner cap for use in a gas burner assembly of a gas cooking appliance which overcomes the aforementioned drawbacks of the prior art in a cost-effective way and which enables an easy manufacturing.
This objective has been achieved by the burner cap as defined in claim 1, the gas burner assembly as defined in claim 14 and the gas cooking appliance as defined in claim 15. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
The burner cap of the present invention comprises at least two formed sheet-metals which together define the top surface and the bottom surface thereof. The formed sheet-metals are joined with each other.
With the present invention, particularly by virtue of the formed sheet-metal structure of burner cap, the manufacturing process has been simplified and the overall costs have been reduced. As the sheet-metals can be formed by comparatively weaker compressive/tension forces, a breakage of the die has been prevented and its lifetime has been prolonged. The weight of the burner cap can be adjusted to the desired amount by choosing the correct thickness of the sheet-metal. With the present invention, particularly by virtue of the formed sheet-metal structure, the burner can be more easily enameled. With the present invention, particularly by virtue of the formed sheet-metal structure, the thermal efficiency of the cooking appliance has also been improved. Thereby, the consumer satisfaction can be increased.
In an embodiment, the burner cap is manufactured from two sheet-metals which are separately formed, for example through a die forming process, in particular through stamping by using a press and a die, a deep drawing process or the like. The two sheet-metals are subsequently joined in order to attain the closed shape which is defined by the respective top surface and the bottom surface of the burner cap. The sheet-metals are joined through a press-fitting process, a welding process or through any other process well known to those skilled in the art. The two metal sheets are formed with various different shapes which facilitate the attachment and the joining process, improve the structural stability, prevent misalignment and dislodging, sustain stable burning of the gas/air mixture and increase the thermal efficiency. The formed sheet-metals have a generally circular outline. However, the two formed sheet-metals may assume an annular shape, an oblong shape or a polygonal shape, in particular a rectangular shape in accordance with the specific design of the cooktop.
In alternative embodiments, either one or both of the two formed metal sheets have an upwardly or downwardly bending skirt-like flange. The flanges may be straight, inclined or curved.
In other alternative embodiments, either one or both of the two formed metal sheets have a raised, lowered, a concave, a convex, a flat, a tapered central section and/or outer section.
The present invention also provides a gas burner assembly which has the burner cap according to the present invention.
The present invention also provides a gas cooking appliance which comprises at least one gas burner assembly according to the present invention.
Additional advantages of the burner cap, the gas burner assembly and the cooking appliance of the present invention will become more apparent with the detailed description of the embodiments with reference to the accompanying drawings in which:
