Description

Field of the invention

The present invention belongs to the field of gas stoves.

Technical background

In a burner of the previously known gas stoves a plurality of extending from the inside to the outside burner rings are usually arranged. However, the flames on the outer raceway ring prevent the air, the oxygen content of which is necessary for combustion flows in the direction of the inner ring of the combustion ring, which eventually leads to incomplete combustion at the inner combustion. To avoid this, usually located in conventional gas stoves on the top or bottom of the cover plate is a secondary air gap for supplying the internal combustion with air. In the latter case, foreign bodies often enter the interior of the gas stove through the secondary air gap during cooking; which may contaminate and at the same time damage the components within the device: To avoid this, it is known from the prior art to provide a burner grid between the outer and the central chamber. Although large solids can be kept away with such a burner grid, the secondary air gap and thus the interior of the gas stove are still accessible to liquid contaminants. In other words, the problem mentioned is still present, at least in part.

In the case of a trained on the top of the cover plate of a gas range Neburn air gap, no liquid can enter through the sub-air gap into the interior of the gas stove, but drops can fall between the outer and the central chamber. In addition, the secondary air gap itself is susceptible to contamination and difficult to clean. Such gas stoves and burners for gas stoves are for example from the documents CN 101178177 A . CN 201187812 Y and WO2009078673 A2 , known.

The description of the prior art does not mean that the described prior art already prior to the filing date of the present Registration is known to those of ordinary skill in the art, unless sufficient proof is offered.

Disclosure of the invention

To solve the above-mentioned problems, the present invention proposes a gas stove.

A gas cooker embodied according to the invention comprises a cover plate and a burner, wherein the burner contains a gas mixing chamber, an outer burner cap and a central burner cap. The gas mixing chamber in turn comprises an outer chamber and a central chamber, wherein the outer burner cap is mounted on the outer chamber and the central burner cap on the central chamber. In addition, the gas cooker has a central drip which is located between the outer chamber and the central chamber and serves to collect and absorb drops falling between the outer chamber and the central chamber. Between the central drip and the outer chamber, a first gap is formed, which opens into the space below the cover plate and supplies the burner with secondary air from below the cover plate. By arranging a central drip, the liquids dripping between the outer and the central chamber can be collected reliably, which increases the ease of cleaning of the gas range. In addition, the supply of the secondary air from below the cover plate, the problem that liquids often get through this supply channel into the interior of the gas stove, solved to some extent.

Optionally, it is provided that on the side facing the central chamber side wall of the outer chamber, a projection is formed, on which the central drip is placed. As a result, on the one hand manufacturing costs are saved and on the other hand simplifies the installation and removal of the central drip for cleaning.

In this way, when supplying the secondary air from below the cover plate, the problem that liquids often pass through this supply channel into the interior of the gas stove, solved substantially from the ground up.

Optionally, it is provided that an air outlet opening is formed in the trim panel, so that the secondary air is successively supplied to the burner through the first, the second gap and the air outlet opening. In this way, when supplying the secondary air from below the cover plate, the problem that liquids often pass through this supply channel into the interior of the gas stove, solved substantially from the ground up. Moreover, the arrangement of the air outlet opening gives the gas stove a better overall look.

For a better understanding of the object, embodiments and advantages of the present invention, this will be explained below in conjunction with the drawings by way of example and not limiting the invention by way of example and preferred embodiments. It should be noted that in the context of the present invention with a gas stove all cooking appliances are called, which have a burner and can be supplied with any type of gas such as natural gas, industrial gas, liquefied petroleum gas, biogas and all other types of gas usable for this area.

In FIGS. 1 to 10 an embodiment of a gas stove according to the invention with a cover plate and a burner is shown, wherein the burner comprises a gas mixing chamber, an outer burner cap 1 and a central burner cap 2. The gas mixing chamber in turn comprises an outer chamber 3 and a central chamber 4, wherein the outer burner cap 1 is placed on the outer chamber 3 and the central burner cap 2 on the central chamber 4. In addition, the gas stove has a central drip 5, which is located between the outer chamber 3 and the central chamber 4 and serves to collect and absorb drops falling between the outer chamber 3 and the central chamber 4. The central drip 5 is made of cold-rolled sheet with an enamel coating.

As in Fig. 4 and 10 is shown, the central drip 5 and the outer chamber 3 are separated from each other by a first gap 9, which opens into the space below the cover plate and from there the burner supplies secondary air.

Again illustration 1 can be seen, located between outer chamber 3 and central chamber 4, a connecting part 7 on which the central drip 5 is placed. On the connecting part 7 are also an ignition electrode and a thermocouple set up or to install.

How out Fig. 2 shows, in the central drip 5, a through hole 12 for carrying out the central chamber 4, the ignition electrode and the thermocouple is formed. In the present Embodiment, this is a common through hole 12, while in practice three through holes can be provided in each case for the central chamber 4, the ignition electrode and the thermocouple. Both on the outer and on the inner edge, so the passage 12 facing the edge of the central drip 5, an upward Anformung is formed, which forms a recess for receiving liquids together with the main body of the central drip 5. The central drip 5 is produced by punching.

How out FIGS. 5 to 10 can be seen, the gas stove additionally has a circular disc-shaped trim panel 6, which is located above the central drip 5. In a direction perpendicular to the cover plate, the trim 6 covers the first gap 9 from. That is, in a plan view of the burner, the first gap 9 is not visible, see FIG. 9 , In the trim 6 a circular air outlet 11 is formed in the middle. In addition, the trim panel 6 is spaced by a second gap 10 from the central drip 5, so that the secondary air is successively fed through the first gap 9, the second gap 10 and the air outlet opening 11 to the burner. Central chamber 4, ignition electrode and thermocouple are exposed through the air outlet opening 11. At the central chamber 4 facing side wall of the outer chamber 3, a projection 8 is formed, on which the trim plate 6 is placed. In concrete, extending at the outer edge of the trim 6, a circumferential side wall evenly down, with the ornamental panel, as in FIG. 10 shown supported on the projection 8. The trim panel 6 is made by punching.

So far, preferred embodiments of the invention have been described, from which further embodiments can be derived by changing or substitution of some features. Thus, for example, on the outer chamber facing the side wall of the central chamber may be provided a projection on which the central drip is placed. Alternatively, the projection on which the central drip is placed, for example, on the side facing the central chamber of the outer chamber are located. Furthermore, between the outer and central chamber, a connecting part may be present to support the trim panel. Moreover, the trim can also be made in one piece with the central drip. The trim panel can also be designed inclined in the region of its air outlet opening to the central drip. Furthermore, the trim panel may be multi-part, ie composed of two or more separate components.
