In one embodiment, the burner area borders directly and immediately on a zone consisting of heat-insulating materials, the heat-insulating materials comprising quartz glass wool, expanded glass and / or hollow glass spheres. In this embodiment, the thermal decoupling of the burner area from the device and optionally from the housing is realized by direct contact with heat-insulating materials. In this embodiment, the device can have additional air shafts through which heat can be removed to the external environment of the multifunction gas burner. In a further embodiment, the burner area is embedded in a container, in particular a bowl. This container surrounding the burner area, in particular this bowl surrounding the burner area, is spatially spaced from the rest of the device and / or from the housing by an air gap or air space surrounding the container or the bowl. In the last embodiment, the thermal decoupling of the burner area is from the device and / or optionally from the housing by means of spatial spacing of the burner area from the device and / or optionally from the housing. The thermal insulation zone thus comprises a zone with heat-insulating materials such as quartz glass wool, expanded glass and / or hollow glass spheres as well as an air space or air shafts.

A burning bed comprises a tube and / or a ceramic. A burning bed cover is optionally arranged above the burning 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 combustion bed in a plane in a circular or polygonal manner. 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 burning bed support can comprise pebbles and / or logs. In one embodiment, these logs are made of a further ceramic, which comprises laminar cavities, which are preferably oriented vertically.

The various firing levels can be switched or regulated, eg by remote control or Smartphone app. The different combustion beds can each be activated differently, that is, they are each supplied with a different amount of gas and / or oxygen via a tube and / or a ceramic.

The term ceramics, also ceramic masses, refers to a large number of inorganic non-metallic materials, which can be roughly divided into the types earthenware, earthenware, stoneware, porcelain and special masses. In general terms, ceramics also serve as a generic term for the shaped and fired products that are used as articles of daily use and ornaments, 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 the second tube are part of a 2-ring burner. There can be n pipes 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 bottle.

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 burner area, preferably in the first and / or second firing stage, the gas flows from the bottom to the top.

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

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

Expanded glass (granulate) is a building material made from recycled waste glass, which is used in the production of lightweight concrete, lightweight plaster, lightweight wall mortar and in thermal insulation panels, thermal insulation fillings, plaster base panels, curtain wall systems and decorative paints. Expanded glass is foamed glass with small, gas-filled pores and can be produced in grain sizes from 0.04-16 mm. The granulate has a closed lattice structure. Expanded glass (granulate) consists of spheres / round grains, which enable versatile processing. Bulk glass is very light and yet pressure-resistant, heat-insulating, alkali-resistant, non-flammable, has a high load-bearing capacity and is not attacked by rodents, pests 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, the second tube surrounding the first tube in a circle.

Through the first gas outlets and the second gas outlets, gas flows from a gas connection, in particular from a gas bottle, into the burner area of the multifunction gas burner.

According to one embodiment it is provided that the cracks are designed to accommodate a) a privacy screen, b) means for supporting a cooking container and c) means with a flat element for receiving or fixing items to be cooked or grilled.

As a result, different application modes of the multifunction gas burner can be implemented. If you insert a privacy screen into the cracks, the multi-function gas burner can be used as a gas fireplace. If means for supporting a cooking container are inserted into the cracks, the multifunction gas burner can be used for cooking food in a wok pan, for example. If you insert means with a flat element into the cracks to hold or fix items of food to be cooked or grilled, the multi-function gas burner can be used for grilling.

According to one embodiment, the privacy screen forms the outer surface of a hollow cylinder or the side faces of a polygon, the privacy screen comprising tempered glass and / or borosilicate glass, the privacy screen in particular being transparent to light.

Different shapes of a gas fireplace can thus advantageously be realized: a hollow cylindrical shape or, for example, a cuboid shape.

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

Borosilicate glass, also borosilicate glass, is a very chemical and temperature resistant glass, which is mainly used for glassware in the laboratory, chemical process engineering and in the household. The good chemical resistance to water, many chemicals and pharmaceutical products (hydrolytic class 1) can be explained by the boron content of the glasses. The insensitivity to sudden temperature fluctuations is a consequence of the low coefficient of thermal expansion of about 3.3 x 10-6 K-1.

According to a particularly preferred embodiment, it is provided that for the thermal decoupling of the device and optionally of the housing from the burner area, the device and optionally the housing are arranged at a distance from one another, i.e. are arranged at a distance between the components. 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, thermal insulation 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 the heat from being conducted from the burner area to the outer edge of the device and to the housing. The thermal insulating rings are made of heat-insulating materials.

According to one embodiment, the device has sleeves and recesses, the sleeves and the recesses being designed to accommodate a) means for cooking or grilling items of food to be cooked or grilled and / or b) means for receiving a cooking container.

As a result, the multifunction gas burner can advantageously be used in a further application mode. If means for cooking or grilling items to be cooked or grilled are inserted into the sleeves and the cutouts, the multifunction gas burner can be used as a grill. If means for holding a cooking container are inserted into the sleeves and the cutouts, the multifunction gas burner can be used as a cooking range. In particular, a wok or wok pan can be placed on the means for holding a cooking container.

A wok is traditionally a tall, curved pan without a flat bottom. The wok corresponds to a spherical cap. There are now so-called wok pans on the market, which are adapted to the kitchen stoves of the western world and have a flat bottom.

In order to be able to cook with a traditional wok, you either need a hard coal stove that is open to the top, or you can alternatively use a wok burner with an open flame (gas) with a power of about 10 kW or more. An ordinary gas stove would also be suitable, but does not bring up the desired temperatures to create wok-hei (aroma). The taste of Wok-Hei captivates with its smokiness, which comes close to what is burned, but does not have the bitter aftertaste.

Wok-Hei can only be reached at very high temperatures. This means that it is very difficult to create the wok-hei aroma on the home stove. With the usual heat sources such as gas, electric or induction stoves, too little heat is given off. The dishes are then braised rather than really fried. Wok Hei needs these high temperatures so that the water in the surface of the food evaporates as quickly as possible. But that 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 strong burner that generates high temperatures, the water evaporates within a very short time. The high temperatures have two effects: the Maillard reaction forms a tasty crust on the surface of the food much faster than in the 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 are then reflected in the dish.

The multifunction gas burner according to the invention generates a sufficiently high thermal energy so that wok hot is produced. The multifunction gas burner according to the invention generates an open flame (gas) with a power from about 10 kW. The heat insulation zone surrounding the burner area prevents the heat generated from spreading onto the device and the housing of the multifunction gas burner.

According to one embodiment, it is provided that the means for cooking or grilling items to be cooked or grilled comprise i) at least one rod or tube or rail with a first end for receiving in one of the sleeves or recesses or cracks, and with a second end , which is designed as a flat element for receiving or fixing items to be cooked or items to be grilled, or ii) a curved in Has a profile arranged substantially perpendicular to the rod or tube.

This allows the multi-function gas burner to be converted quickly and easily in an advantageous manner: from a grill device with at least one rod or tube or rail with a first end for receiving in one of the sleeves or recesses or cracks, and with a second end, which as Flat element for receiving or fixing pieces of food to be cooked or grilled is designed to form a cooking range, in particular a wok hearth, the means for cooking having a curved profile arranged essentially perpendicular to the rod or tube.

According to one embodiment, the means for supporting a cooking container comprise a straight rod element and an obliquely angled rod element, the straight rod element being designed to be received by one of the cracks, the obliquely angled rod element being designed to partially carry a cooking container.

The means for supporting a cooking container can simply be inserted into the cracks around the burner area with their straight bar elements. If the obliquely angled rod elements face each other towards the center of the burner area, these together form a support for receiving a cooking container or a wok.

According to one embodiment, it is provided that the privacy screen has an upper edge facing away from the burner area, the upper edge being designed to carry a frame for receiving a cooking container, the frame comprising a ring with radially projecting rails, each with a kink, wherein the respective kink is designed to grip around the upper edge of the privacy screen facing away from the burner area.

The multifunction gas burner can also be converted into a cooking range with the privacy screen around the burner area. A frame for holding a cooking container can be mounted on the upper edge of the privacy screen. In the case of a cylindrical privacy screen, the frame comprises a ring with radially projecting rails, each with a kink, which in each case engages around the upper edge of the privacy screen. A cooking container or wok can be inserted into the ring.

According to one embodiment, the upper edge of the privacy screen is also designed to carry means with a rod or tube or rail designed as a first end, the second end of the means being designed as a spit for receiving items to be cooked or grilled.

This allows you to quickly and easily place skewers for grilling over the flames of the multi-function gas burner.

According to one embodiment, it is provided that the multifunction gas burner in one embodiment is a) a gas fireplace, b) a gas grill, in particular for grilling or smoking cooked or grilled items such as fish, potatoes, vegetables or meat products, or c) a wok.

The multifunction gas burner according to the invention combines the functions of a gas fireplace with its open flames, a gas grill with means for impaling food and a wok fireplace with its high temperature in the firing area. Different firing levels can be set. Adequate thermal insulation of the device and the housing of the multifunction gas burner is provided at all firing levels.

According to one embodiment, the privacy screen is multi-part and removable.

The multifunction gas burner has a modular structure. In order to convert the multifunction gas burner from a gas fireplace into a grill or a cooker, the privacy screen can be completely removed from the cracks. The privacy screen can be made in one piece or in several parts.

The invention further relates to a multifunction gas burner comprising the device according to the invention.

Further details, features and advantages of the invention result from the drawings, as well as from the following description of preferred embodiments with reference to the drawings. The drawings illustrate only exemplary embodiments of the invention, which do not restrict the essential inventive concept.
