Description

The present invention relates to a sectioned safety pane for a multifunction gas burner and a kit comprising a sectioned safety pane according to the invention and a multifunction gas burner.

In the state of the art there are so-called ethanol stoves with glass fronts, which can be used inside and outside the house. The partly free-standing ethanol stoves are used like fireplaces and are mainly intended to create a nice ambience.

It is an object of the present invention to provide a safety pane for a multifunction gas burner having different functions and burner stages. For this purpose, the safety pane must be particularly heat-resistant and unbreakable, and designed for a, preferably reversible, combination with the multifunction gas burner.

The object of the present invention is achieved by a sectioned safety pane according to the invention, comprising at least a first layer of glass selected from mineral glass or organic glass, the sectioned safety pane having the shape of a lateral surface of a three-dimensional body. The sectioned safety pane is preferably transparent, in particular permeable to light.

A pane is by definition a transparent material made of glass, including organic or mineral glass, and viewing windows derived therefrom of unspecified shape. Glasses are solids. Their structure is not in thermodynamic equilibrium. The term safety pane refers only to the function of the pane as a delimitation from potentially dangerous, such as hot, things, especially fire, and is not to be understood as corresponding to a specific DIN standard or legal requirement. Many plastics, such as Plexiglas, also fall into the glass category because of their amorphous structure and a glass transition, although they have a completely different chemical composition than silicate glasses. They are therefore referred to as organic glass

The sectioned safety pane is preferably used in all four spatial directions around the at least one flame, which is generated by a gas burner.

Accordingly, the sectioned safety pane has the shape of a lateral surface of a three-dimensional body, in particular without end faces. Thus, the space enclosed by the sectioned safety pane is open at the bottom, towards the point of origin of the flame, and at the top, towards the tip of the flame.

The three-dimensional body, whose lateral surface corresponds to the shape of the sectioned safety pane, preferably has a polygonal or round base area, the three-dimensional body particularly preferably corresponding to a pyramid, a cylinder, a cuboid or a square. The sectioned safety pane accordingly preferably has the shape of the lateral surface of a pyramid, a cylinder, a cuboid or a square.

The sectioned safety pane consists of several separate sections. The sectioned safety pane is accordingly formed from at least two, preferably two to 16, particularly preferably four, alternatively eight, partial sections which together form the shape of the lateral surface of a three-dimensional body such as a pyramid, a cylinder, a cuboid or a square. The shape of the lateral surface optionally has interruptions, in particular vertical interruptions, in particular at the points at which the at least two partial sections meet.

The at least two sections are interconnected. In particular, a first subsection is connected to a second, adjacent subsection. The subsections can be connected by any of the connection options known to those skilled in the art.

In a preferred embodiment, the at least two sections are connected to one another by means of a flexible connection, so that the sections can be angled relative to one another and the lateral surface of a three-dimensional body formed by the sections can be folded open so that it is present as a planar surface. This is particularly useful for transporting and storing the sectioned safety pane.

In one possible embodiment, the flexible connections for connecting at least two adjacent sections of the sectioned safety pane are formed by hinges or eyelets, preferably made of stainless steel. However, all other bendable hardware items or hardware items that allow the sections to be bent relative to one another and corresponding plastic components are also possible, which are preferably connected by means of at least one bore in the sectioned safety disc, in particular anchored in the section to be connected or glued to it.

In a preferred embodiment, the flexible connections consist of eyelets, which are anchored by means of bores in the edge of each subsection lying in the direction of the adjacent subsection.

In an alternative embodiment, the flexible connection and/or the hinge is formed from a layer or film of an elastic, preferably heat-resistant, polymer or polymer composition. The flexible layer or the flexible film as a connection between two adjacent sections is preferably present integrally with the respective adjacent sections, is glued to them or is cured on them during the manufacturing process or cooled from the melt.

Silicones and radiation-crosslinked thermoplastics such as polyvinyl chloride, polyolefin polyethylene and particularly preferably polyurethane or mixtures thereof are preferably used as adhesives and/or as elastic, heat-resistant polymers for producing the flexible connection between two adjacent sections.

The connection is preferably only present in a partial area of the section, so that there are interruptions between the sections. Alternatively, the connection runs the full height of the section.

According to a special embodiment, there can be a detachable connection between at least two of the at least two partial sections. The detachable connection can consist of a detachably attached, preferably attachable layer, in particular as a planar connecting piece, comprising the heat-resistant polymers mentioned, which encompasses the lateral edge of a section lying in the direction of the adjacent section. For this purpose, the planar connecting piece can have a groove on each of two opposite sides for receiving the lateral edge of a partial section.

In a further embodiment, the flexible connections consist of eyelets, which are anchored by means of bores in the edge of each subsection lying in the direction of the adjacent subsection, and the eyelets can be reversibly opened and closed for a detachable connection. In this embodiment, the eyelets are preferably connected to one another by a web (similar to a spiral binding) and can be opened and closed, particularly preferably simultaneously and/or with one hand. In this embodiment, the eyelets and the web are preferably made of a polymer or a polymer composition, more preferably a thermoplastic polymer or a thermoplastic polymer composition according to the invention.

Alternatively, the at least one detachable connection can consist of a system consisting of one or preferably two connection means, such as a Velcro fastener, a hook and a button. The hook in this embodiment is movably attached to a first section and is placed over the button on the second section to fasten to connect the sections together. The embodiment with at least one detachable connection serves in particular to facilitate dismantling for storage and transport of the sectioned safety pane. This makes it possible to fold the lateral surface of a three-dimensional body formed by the sections, similar to an accordion, and to place the sections on top of one another. Alternatively, all of the connections between the at least two subsections can also be detachable.

The structure according to the invention ensures air circulation when used with a multifunction gas burner, so that the multifunction gas burner, in particular the housing of the multifunction gas burner, does not have to have any additional ventilation slots. In addition, the sectioned safety pane can also be used as a shelf for grilled food or the like.

The sectioned safety pane is particularly heat-resistant and unbreakable, especially when used as a shelf for grilled food. Therefore, the sectioned safety pane consists of mineral glass and/or organic glass. The sectioned safety pane can have multiple layers.

The sectioned safety pane preferably comprises at least one layer of mineral glass.

The at least one second layer consists of mineral glass, preferably comprising tempered glass and/or borosilicate glass.

Tempered glass is glass in which mechanical stresses are generated in the material through heat treatment, thereby increasing the fracture resistance to mechanical or thermal stress.

Borosilicate glass, also known as borosilicate glass, is a very chemical and temperature-resistant glass that is mainly used for glassware in the laboratory, in chemical engineering and in the home becomes. The good chemical resistance to water, many chemicals and pharmaceutical products (hydrolytic class 1) is explained by the boron content of the glasses. The insensitivity to sudden temperature changes is a result of the low coefficient of thermal expansion of about 3.3 x 10-6 K-1.

Furthermore, the sectioned safety pane comprises, preferably consists, of at least one first layer comprising at least one thermoplastic polymer or a thermoplastic composition comprising at least one thermoplastic polymer.

The at least first layer of the sectioned safety pane according to the invention particularly preferably consists of at least one thermoplastic polymer or a thermoplastic composition comprising at least one thermoplastic polymer selected from poly(meth)acrylates and poly(aryl)etherketones (PAEK and PEK), such as polymethyl methacrylate (PMMA), Polyetherketone (PEK), polyetheretherketone (PEEK, also 4-hydroxyphenyl(4-phenoxyphenyl)methanone), polyetherketoneketone (PEKK), polyetheretheretherketone (PEEEK), polyetheretherketoneketone (PEEKK), polyetherketoneetherketoneketone (PEKEKK), preferably polyetherketone poly(meth)acrylates and/or or poly(aryl) ether ketones (PAEK and PEK), such as polymethyl methacrylate (PMMA), polyether ketone (PEK), polyether ether ketone (PEEK, also 4-hydroxyphenyl(4-phenoxyphenyl)methanone), polyether ketone ketone (PEKK), polyether ether ether ketone (PEEEK), polyether ether ketone ketone (PEEKK), polyether ketone ether ketone ketone (PEKEKK), preferably polyether ketone, polyvinyl butyr al (PVB), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA), polyacrylate (PA).

The at least one first layer is designed as a particularly plate-like disc, preferably made of cast resin, and/or as a film. A film is a homogeneous, very thin (typically 2 µm to 0.5 mm wall thickness) sheet-like structure, whereas a disk is understood to be a thicker sheet-like structure (> 0.5 mm wall thickness). Furthermore, a film is to be understood as a flexible structure in contrast to the pane. The first layer comprising at least one thermoplastic polymer or a thermoplastic composition comprising at least one thermoplastic polymer is preferably configured as a disc.

A first layer, which is designed as a disc, preferably comprises at least one thermoplastic polymer or a thermoplastic composition comprising at least one thermoplastic polymer selected from poly(meth)acrylates and/or poly(aryl)etherketones (PAEK and PEK), such as polymethyl methacrylate (PMMA ), polyether ketone (PEK), polyether ether ketone (PEEK, also 4-hydroxyphenyl(4-phenoxyphenyl)methanone), polyether ketone ketone (PEKK), polyether ether ether ketone (PEEEK), polyether ether ketone ketone (PEEKK), polyether ketone ether ketone ketone (PEKEKK), preferably polyether ketone.

A first layer, which is designed as a film, preferably comprises at least one polymer or a composition comprising at least one polymer selected from polyvinyl butyral (PVB), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA), polyacrylate (PA), polymethyl methacrylate (PMMA) and polyurethane (PUR) includes. Most preferably, the film comprises polyvinyl chloride (PVC), alternatively polyvinyl butyral (PVB).

In particular, the sectioned safety pane according to the invention is heat-resistant up to a temperature of greater than or equal to 100°C, preferably 300°C, particularly preferably 350°C, in particular up to 370°C.

Polymethyl methacrylate (PMMA, also acrylic glass) is a transparent thermoplastic known to those skilled in the art.

Poly(aryl)etherkethones are high-temperature materials with a molecular backbone that contains alternating ketone (R-CO-R) and ether (R-O-R) functionalities. The most common are polyaryl ether ketones (PAEK), in which there is an aryl group linked in the (1,4) position between the functional groups. The resulting very rigid backbone gives the materials very high glass transition and melting temperatures compared to other plastics.

The poly(aryl) ether ketones preferably have a molecular weight of M _w =50,000 to 800,000, preferably from 100,000 g/mol to 500,000 g/mol.

Polymethyl methacrylate (PMMA, also acrylic glass) is a transparent thermoplastic known to those skilled in the art.

Poly(aryl)etherkethones are high-temperature materials with a molecular backbone that contains alternating ketone (R-CO-R) and ether (R-O-R) functionalities. The most common are polyaryl ether ketones (PAEK), in which there is an aryl group linked in the (1,4) position between the functional groups. The resulting very rigid backbone gives the materials very high glass transition and melting temperatures compared to other plastics.

The poly(aryl) ether ketones preferably have a molecular weight of M _w =50,000 to 800,000, preferably from 100,000 g/mol to 500,000 g/mol.

The sectioned safety pane or the partial sections have a thickness of at least 0.5 cm. The sectioned safety pane preferably has an overall thickness of at least 0.1 cm, particularly preferably 2.5 cm.

The sectioned safety pane preferably has a smooth outer edge, in particular a planar outer lower edge, and in particular no fastening means such as locking cams or other elevations. The sectioned safety pane can thus be placed with the planar lower edge on the surface of a multifunction gas burner. By saving on fasteners, the manufacturing costs are reduced and the complexity of manufacturing is reduced.

Another object of the present invention is a kit comprising a sectioned safety pane according to the invention and a multifunctional gas burner.

In one embodiment, the multifunction gas burner is a) a gas fireplace, b) or a gas grill, in particular for grilling or smoking items to be cooked or grilled, such as fish, potatoes, vegetables or meat products, with the item to be grilled not being inside the housing of the Multifunction gas burner, but is placed above the housing.

The multifunctional gas burner preferably comprises a device as at least part of a substantially horizontal plane of a housing, the device comprising a burner area, the burner area having a first combustion bed with a first tube with first gas outlets and optionally with a first ceramic for a first combustion stage and optionally includes a second combustion bed with a second tube with second gas outlets and/or with a second ceramic for a second firing stage, wherein the first and the second tube and the first ceramic and the second ceramic each have a connection to a gas supply, in particular a gas bottle, exhibit.

The sectioned safety pane preferably runs around the burner area of the multifunction gas burner on all four sides, with the burner area being open at the top, with the multifunction gas burner in particular not having a cover.

The housing of the multifunction gas burner preferably has the shape of a prism, a cuboid or a cylinder. The housing of the multifunction gas burner is preferably at least partially, particularly preferably completely, solid. The housing can consist of all common materials. The housing is preferably made of natural stone, such as marble or granite, mineral glass or laminated glass, such as tempered glass or ceramic. Alternatively, the housing is made of metal or metal alloys such as stainless steel or cast iron.

The multifunction gas burner preferably has a collecting tray in the burner area, between the first combustion bed and the first tube, for collecting impurities, which is arranged in the multifunction gas burner in a removable manner.
The drip tray preferably has the same base area as the housing of the multifunction gas burner and can have a planar surface, in particular like a plate, or a concave surface, in particular slightly to strongly curved, such as a bowl. The drip tray can be made of any material, such as stainless steel, cast iron, aluminum, heat-resistant plastic or cardboard and coated, preferably coated with perfluorinated and polyfluorinated alkyl compounds.

Impurities can be fats, oils and ash in particular and can drip or fall, for example from food to be grilled, into the multifunction gas burner or into the combustion bed of the multifunction gas burner. In particular, the drip tray allows the multifunction gas burner to be cleaned quickly and easily.

The drip tray is preferably inserted and removed through a slot in the housing of the multifunction gas burner. The slot preferably runs horizontally across at least an entire side of the housing for up to three and a half sides of the housing. Alternatively, the drip tray can be pushed into the housing from above and under the at least first tube for insertion. In this embodiment, the collecting tray is also pushed out from above under the at least first tube for removal. For this purpose, the sectioned safety pane can be completely or partially removed from the housing of the multifunction gas burner.

The drip tray is preferably a disposable drip tray. Accordingly, the drip tray is preferably designed to be disposed of after it has been used once and replaced with a new drip tray. For this purpose, the drip tray is preferably made of recyclable materials such as aluminum, plastic or cardboard. Preferably, the drip pan is made of aluminum or a polymer or a polymer composition comprising per- and polyfluorinated alkyl compounds (PFTs). Aluminum trays for placing food to be grilled on gas grills are already known for this purpose. Per- and polyfluorinated alkyl compounds are aliphatic organic compounds such as polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), fluorinated ethylene propylene or perfluoroalkoxy polymer (PFA) in which the hydrogen atoms on the carbon skeleton have been completely replaced by fluorine atoms on at least one carbon atom in such a way that the general Formula CnF2n+1- applies.

The multifunctional gas burner with a housing has, in particular, a device, the device forming at least part of a substantially horizontal plane of the housing, and the device comprising a burner area, the burner area having a first combustion bed with a first tube with first gas outlets and optionally with a first ceramic for a first firing stage and optionally a second firing bed with a second tube with second gas outlets and/or with a second ceramic for a second firing stage, the first and second tubes and the first ceramic and the second ceramic each having a Have connection to a gas supply, in particular a gas bottle.

The at least first tube with first gas outlets and the optional second tube with second ones Gas outlets preferably run in a circular or spiral shape within the burner area.

The housing with an essentially horizontal plane correspondingly has an edge running around the burner area, on which the sectioned safety pane can be placed.

In an alternative embodiment, the housing has a preferably circumferential edge on the edge, particularly preferably designed in shape and size to accommodate the sectioned safety pane with a precise fit, in particular to prevent the sectioned safety pane from slipping on the housing. The preferably circumferential edge accordingly forms the shape or sections of a polygon, circle or ellipse, which corresponds in particular to the size and shape of the end faces of the three-dimensional body, whose lateral surface corresponds to the shape of the sectioned safety pane.

Food to be grilled, holders for food to be grilled or cooking utensils such as saucepans, pans or woks can optionally be placed on the sectioned safety pane.

A wok is traditionally a high, curved pan without a flat bottom. So the wok corresponds to a spherical cap. So-called wok pans, which are adapted to western kitchen stoves and have a flat base, are now also on the market.

In order to be able to cook with a traditional wok, either a hard coal oven that is open at the top is required, or alternatively you can use a wok burner with an open flame (gas) with an output of around 10 kW or more. An ordinary gas stove would also be suitable, but does not produce the desired temperatures for wok-hei (aroma) to develop. The taste of Wok-Hei impresses with its smokiness, which comes close to being burnt, but without the bitter aftertaste of the same.

Wok-Hei can only be achieved with very high temperatures. This means that it is very difficult to produce the wok-heat aroma on the stove at home. With the usual heat sources such as gas, electric or induction stoves, too little heat is given off. The dishes are then stewed rather than really fried. However, wok hei needs these high temperatures so that the water on the surface of the food evaporates as quickly as possible. However, this requires a large amount of thermal energy. The water escaping from the food lowers the temperature of the wok to the boiling point, a weak stove does not have enough energy to evaporate the water immediately. With a powerful burner that generates high temperatures, the water evaporates within a very short time. The high temperatures have two effects: the Maillard reaction causes a tasty crust to form on the surface of the food much faster than in a pan on a normal stove. The second effect is the ignition of the oil. The sudden decomposition of the oil creates new flavor components, which in turn are reflected in the dish.

The multifunction gas burner according to the invention generates a sufficiently high level of thermal energy to create a wok hei. The multifunction gas burner according to the invention generates an open flame (gas) with an output of around 10 kW or more. The thermal insulation zone surrounding the burner area prevents the resulting heat from spreading to the device and the housing of the multifunction gas burner.

According to one embodiment, it is provided that the first combustion bed covering made of a further ceramic comprises first imitation logs and/or first pebbles, and/or the second combustion bed covering made of the further ceramic comprises second imitation logs and/or second pebbles.

The impression of a real open fire is thus conveyed in an advantageous manner. A first firing stage, which is at a temperature of 800 to 1100 degrees Celsius, can be realized by the first firing bed support made of the first ceramic in the form of first imitation logs and/or first pebbles. A second firing stage, the temperature of which is higher than that of the first firing stage, can be realized by the second firing bed covering made of the second ceramic in the form of second imitation logs and/or second pebbles. The second firing stage can be switched to the first firing stage.

The first and second mock wood logs and the first and second pebbles have laminar voids which are arranged vertically. These laminar cavities are permeable to gas and/or oxygen.

According to one embodiment, the device comprises a thermal insulation zone, with the thermal insulation zone surrounding the burner area, so that the device and the housing are preferably thermally decoupled from the burner area.

The thermal insulation zone in the edge area of the burner area advantageously prevents overheating of the device and of the housing of the multifunction burner. A thermal decoupling is realized by spacing or insulation. In a preferred embodiment, the thermal decoupling, in particular from the device and/or the housing, can take place by means of an air shaft running around the burner area. The air duct, preferably above the plane of the apparatus, has an orientation between vertical to horizontal facing outward from the burner area. More preferably, the angle of the duct is from 90° to 10° with respect to the plane of the device. In one embodiment, the thermal insulation zone has an air shaft that preferably runs partially or completely around the burner area, preferably an air shaft that runs around the entire combustion area and at least partially thermally decouples the burner area from the device

Thermal insulation is the reduction of the passage of thermal energy through an envelope to protect a space or body from cooling or heating. Other, more colloquial terms for thermal insulation are thermal insulation and thermal insulation.

On the one hand, the device preferably corresponds to a planar upper side of the housing of the multifunction gas burner and preferably also comprises the burner area. The device can be designed integrally or in multiple parts and in particular can form at least part of the upper side of the housing and have a burner area comprising a first and optionally a second combustion bed. The device is preferably in several parts and comprises part of a substantially horizontal plane of the housing, optionally an insulating element or insulating area or insulating ring(s) running partially around the burner area, and the burner area as at least one further part.

The burner area preferably includes the alternatives: i) a first combustion bed with a first tube with first gas outlets for a first combustion stage and a second combustion bed with a second tube with second gas outlets for a second combustion stage, or ii) a first combustion bed with a first ceramic for a first firing stage and a second firing bed with a second tube with second gas outlets for a second firing stage, or iii) a first firing bed with a first ceramic for a first firing stage and a second firing bed with a second ceramic for a second firing stage, or iv) a first firing bed with a first tube with first gas outlets for a first firing stage and a second firing bed with a second ceramic for a second firing stage.

In one embodiment, the burner area borders directly and immediately on a zone consisting of heat-insulating materials, with the heat-insulating materials comprising quartz glass wool, expanded glass and/or hollow glass spheres. In this embodiment, the burner area is thermally decoupled from the device and optionally from the housing by direct contact with thermally insulating materials. In this embodiment, the device can have additional air ducts, through which heat can be transported away to the outside of the multifunctional gas burner. In a further embodiment, the burner area is embedded in a container, in particular a shell. This container enclosing the burner area, in particular this shell enclosing the burner area, is spatially spaced apart from the rest of the device and/or from the housing by an air gap or air space surrounding the container or the shell. In the last embodiment, the thermal decoupling of the burner area is the device and/or optionally realized by the housing by spatially spacing the burner area from the device and/or optionally from the housing. The thermal insulation zone thus includes a zone with thermally insulating materials such as quartz glass wool, expanded glass and/or hollow glass spheres as well as an air gap or air shafts.

A combustion bed comprises a tube and/or a ceramic. A firing bed support is optionally arranged above the firing bed. The first and the second combustion bed can be arranged next to one another in one plane, or the second combustion bed surrounds the first in a circle or polygon-like manner Firing bed in one plane. The first combustion bed support is arranged above the first combustion bed, the second combustion bed support is arranged above the second combustion bed. A fire bed overlay may include pebbles and/or logs. In one embodiment, these logs are a further ceramic comprising laminar cavities which are preferably vertically oriented.

The different firing stages can be switched or regulated, e.g. by remote control or smartphone app. The various combustion beds can each be activated differently, i.e. are each supplied with a different quantity of gas and/or oxygen via a pipe and/or a ceramic.

In technical terms, the term ceramics, including ceramic masses, refers to a large number of inorganic, non-metallic materials that can be roughly divided into the types of earthenware, earthenware, stoneware, porcelain and special masses. In general, ceramics also serves as a generic term for the shaped and fired products that are used as everyday and ornamental objects, components or tools. A distinction is made between clay ceramics and glass ceramics.

The ceramic for the multifunction gas burner has laminar cavities which are arranged vertically. Gas and/or oxygen can flow through these vertical laminar cavities. The shaft ratio, ratio of gap width to height, is usually around 1:10.

The first and second tubes are part of a 2-ring burner. There can be n tubes arranged in the burner area, which are part of an n-ring burner. The tubes usually have a connection to a gas supply, in particular a gas cylinder.

The term burner includes all types of burners such as T-type burner, infrared burner, RV burner, M-type burner, S-type burner, ST burner, M-140 burner, LPG burner, buffet burner, 2-ring burner, 3 ring burner. In the burner according to the invention, in particular the burner area, preferably in the first and/or second firing stage, the gas flows from bottom to top.

According to one embodiment, the thermal insulation zone comprises quartz glass wool, expanded glass and/or hollow glass spheres, with the degree of thermal insulation being greater than or equal to 60% in particular.

As a result, the first and the second combustion bed and the first and the second combustion bed support can be thermally decoupled from the device and the housing of the multifunction gas burner in an advantageous manner.

Expanded glass (granulate) is a building material made from recycled glass, which is used in the manufacture of lightweight concrete, lightweight plaster, lightweight masonry mortar and in thermal insulation panels, thermal insulation fill, plaster base panels, curtain wall systems and decorative paints. Expanded glass is foamed glass with small, gas-filled pores and can be produced with grain sizes of 0.04-16 mm. The granules have a closed lattice structure. Expanded glass (granules) consists of spheres/round grains that enable versatile processing. Fillers made of expanded glass are very light and yet pressure-resistant, thermally insulating, alkali-resistant, non-flammable, have a high resilience and are not attacked by rodents, vermin and fungi.

According to one embodiment, it is provided that the first tube with the first gas outlets and the second tube with the second gas outlets are bent in a ring shape, with the second tube surrounding the first tube in a circle. Gas flows through the first gas outlets and the second gas outlets from a gas connection, in particular from a gas bottle, into the burner area of the multifunctional gas burner.

According to a particularly preferred embodiment, it is provided that for thermal decoupling of the device and optionally the housing from the burner area, the device and optionally the housing are arranged at a distance from one another, i.e. the components are arranged at a distance from one another. Additionally or alternatively, thermal insulating rings can be arranged around the burner area. The spacing of the device from the burner area and/or the burner area from the housing is preferably at least 0.5 cm, preferably 1 cm, more preferably 0.5 to 5 cm. Alternatively 1.5 cm to 5 cm.

According to one embodiment, it is provided that thermal insulating rings are arranged around the burner area for thermal decoupling of the device and the housing from the burner area.

Thermal insulating rings advantageously prevent heat from being conducted from the burner area to the outer edge of the device and to the housing. The thermal insulation rings consist of heat-insulating materials.
