Description

The invention relates to a device (4) for a multifunction gas burner (1) with a housing (7), the device (4) being designed as at least one substantially horizontal plane of the housing (7), the device (4) having a Burner area (2), wherein the burner area (2) comprises a first combustion bed (28a) with a first tube (2a) with first gas outlets and optionally with a first ceramic (9a) for a first combustion stage and optionally a second combustion bed (28b). a second tube (2b) with second gas outlets and/or with a second ceramic (9b) for a second firing stage, wherein the first and the second tube (2a, 2b) and the first ceramic (9a) and the second ceramic (9b ) each have a connection to a gas supply, in particular a gas bottle (22), and wherein the device (1) has at least one first coupling element (5a, 5b), on which at least one second coupling element (101a, 101b, 101c, 101d) of a With by means (100) with a flat element (103) for receiving or fixing items to be cooked or grilled by means of a connection, the connection being selected from plugging, latching, screwing, clamping and/or magnetic connection, and a multifunctional gas burner (1 ) comprising the device (4). In addition, the subject of the invention is the use of a means (100) with a flat element (103) for receiving the fixing of items to be cooked or grilled with a multifunctional gas burner (1) comprising the device (4). A preferred snap-fit connection includes at least a luer-lock coupling of at least a first and a second coupling element. The invention also relates to a means with a second coupling element with a flat element, the flat element preferably being made of wood, in particular cedar wood, ceramics, glass or a hybrid material.

In the prior art, means with a flat element, such as flame salmon boards, are only used with fire bowls. However, this use has the disadvantage that the temperature of the fire source and thus the desired degree of cooking of the food to be cooked or grilled cannot be regulated. Furthermore, the positioning of the food to be cooked or grilled in relation to the fire source cannot be varied. Furthermore, the heat and location of the flames are difficult to control. With a gas grill, the heat can be precisely adjusted and the location of the flames can be adjusted.

The present invention is therefore based on the object of providing a device for a multifunction burner with which uniform grilling or cooking of grilled food, preferably fish, that cannot be fastened on skewers is made possible. In particular, a device should be provided that can be integrated into a conventional multifunction gas burner. In addition, the device should have different functions and burner stages without the housing of the multifunction gas burner overheating.

The object of the present invention is achieved by a device for a multifunctional gas burner, which has at least a first coupling element, in particular an element protruding from the surface of the device and/or a magnetizable or magnetic surface belonging to the device, on which at least a second coupling element, in particular a cap, nut, clip and/or a magnet, of a means with a flat element for receiving or fixing pieces of food to be cooked or grilled, can be fastened by means of a connection, the connection being selected from plugging in, screwing on, clamping and/or magnet Connect.

Any barbecue accessory that is suitable for receiving or, in particular on both sides, fixing pieces of food to be cooked or grilled, in particular fish, such as salmon (saddle), can be used as a means for holding or fixing pieces of food to be cooked or grilled. The at least one grilled food fastening element is preferably a fish roaster with a basket as a flat element or a flamed salmon board with a board, in particular a wooden or metal board or ceramic board, as a flat element.

The means with a flat element is preferably used for the preparation of flamed salmon. Flambee salmon is a dish originating from Finland, in which the salmon parts were prepared by the natives on an open fire and served preferably at the time of midsummer night in June. In the meantime, flamed salmon - also called fire salmon - is often offered at Christmas markets. Special flame salmon boards for vertical attachment to fire bowls or grills are known for domestic use. However, these have the disadvantage that, due to the different distances from the fire source, the part of the laugh in question is not evenly cooked. For this reason, in a particularly preferred embodiment, the means used according to the invention with a flat element have a joint, in particular a ball joint, with which the flat element can be pivoted in the direction of a fire source.

According to the invention, the fire source is the burner area of the device, so that the means with a flat element for receiving or fixing pieces of food to be cooked or grilled are preferably arranged around the burner area. Elements set up at predetermined positions on the surface of the device or, alternatively, the at least partially magnetizable or magnetic surface of the device can be used as the first coupling elements. The first coupling element is preferably present at least partially in the form of a magnetizable or magnetic surface belonging to the device. In addition, the device is particularly preferably thermally decoupled from the burner area.

The invention relates to a device for a multifunctional gas burner with a housing, 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 a 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, 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 cylinder, and wherein the device has at least a first coupling element, to which at least a second coupling element of a means with a flat element for receiving or fixing pieces of food to be cooked or grilled by means of a Connection is attachable, wherein the connection is selected from plugging, screwing, clamping and / or magnet connection.

According to the invention, the at least one first and second coupling element therefore interact by means of a connection selected from plugging, screwing, clamping and/or magnetic connection. This means that the at least one second coupling element is placed on the at least one second coupling element, in particular the surface of the device, from above and/or from the side. In this sense, the at least one first and second coupling element in particular do not interact by means of a connection selected from plugging in, pushing in and/or inserting.

The at least one first coupling element is preferably a male coupling element, such as a (threaded) pin protruding from the surface of the device, profile such as H profile, U, V, T, X and/or Y profile , or sheet metal or alternatively a surface belonging to the device. In particular, the at least one first coupling element is not a crack, sleeve and/or recess. At the same time, it can be preferred if the at least one second coupling element is preferably a female coupling element, such as a cap, nut or clamp.

In this sense, in a preferred embodiment of the device, the at least one first coupling element is an element protruding from the surface of the device, in particular a projection, pin, pin, ridge, on which the at least one second coupling element of the means has a flat element for receiving or Definition of items to be cooked or grilled can be plugged in, screwed on or clamped. For example, the at least one first coupling element can be a pin or a profile to which a second coupling element in the form of a cap or a profile can be attached. In addition, the at least one first coupling element can also have an external thread, onto which a second coupling element with an internal thread can be screwed. Or the at least one first coupling element is a projection on which a second coupling element designed as a clamp can be clamped.

In an alternative preferred embodiment of the device, the at least one first coupling element is a magnetizable and/or magnetic surface belonging to the device and the at least one second coupling element of the means with a flat element for receiving or fixing items to be cooked or grilled is a magnet. Accordingly, it can also be preferred according to the invention if the at least one first coupling element does not protrude from the surface of the device, but this is merely magnetizable and/or magnetic. However, the surface of the device can also be provided with at least one first coupling element in the form of a magnet, while the at least one second coupling element can only be magnetized and/or is magnetic.

The advantage of a magnetic solution is that the means with a flat element for receiving or fixing pieces of food to be cooked or grilled can be positioned at almost any point on the device, whereas an element protruding from the surface of the device has a fixed, predetermined position . Nevertheless, it can be advantageous according to the invention if the means with a flat element for receiving or fixing items to be cooked or grilled in the direction of the Bren nerbereichs movable, in particular pivotable, is. This can be done by a joint, such as a ball joint or a lockable joint, which has the means with a flat element.

In a particularly preferred embodiment, the at least one second coupling element is fixed via a connecting piece to the flat element of the means for receiving or fixing items to be cooked or grilled. The connecting piece is connected to the at least one second coupling element and/or to the flat element, preferably via a hinge or joint, so that the position of the flat element in relation to the burner area can be varied even after it has been attached to the at least one second coupling element . The connecting piece can be fixed, in particular detachably, at any point on the flat element, for example at its end or on its rear side. The at least one second coupling element is preferably designed as an integral part of the connecting piece. However, the at least one second coupling element can also be fixed directly to the flat element.

Furthermore, it can be preferred if the connecting piece comprises a joint, in particular a ball joint, with which the flat element of the means for receiving or fixing pieces of food to be cooked or grilled can be pivoted in the direction of the burner area. The joint preferably divides the connecting piece into two sections, which act as arms and allow the flat element to pivot in two directions.

In a further preferred embodiment of the invention, the device has slits, the slits being arranged such that they run at a distance at least partially to preferably completely around the burner area. The cracks surround the burner area. The cracks can be designed as grooves. Means for the functional conversion of the multifunction gas burner can be inserted into the cracks.

In this sense, it can be preferred if the slots are designed to accommodate a) a protective pane and/or optionally b) means for supporting a cooking container.

As a result, different application modes of the multifunction gas burner can be implemented. If you put a protective disc in the cracks, the multifunction gas burner can be used as a gas fireplace. If means for supporting a cooking container are inserted into the cracks, the multifunctional gas burner can be used for cooking food, for example in a wok pan.

The protective pane preferably forms the lateral surface of a hollow cylinder or the side faces of a polygon, with the protective pane comprising tempered glass and/or borosilicate glass, with the protective pane in particular being transparent to light. In this way, different shapes of a gas fireplace can be realized in an advantageous manner: a hollow cylindrical shape or, for example, a cuboid shape.

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 used primarily for glassware in the laboratory, in chemical engineering and in the home. 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 × 10-6 K-1.

The protective screen is particularly preferably multi-part and removable.

According to one embodiment, it is provided that the protective pane has an upper edge facing away from the burner area, with the upper edge being designed to support a frame for receiving a cooking container, the frame comprising a ring with radially projecting rails, each with a kink point, wherein the respective kink point is designed to encompass the upper edge of the protective pane facing away from the burner area. Furthermore, the upper edge of the protective disc is preferably adapted to support means having a rod or tube or rail formed as a first end, the second end of the means being formed as a skewer for receiving pieces of food to be cooked or grilled. This is a quick and easy way to arrange skewers for grilling over the flames of the multifunction gas burner.

The multifunction gas burner can also be converted into a cooking stove when the protective pane is in place around the burner area. A frame for holding a cooking container can be mounted on the upper edge of the protective pane. In the case of a cylindrical protective disk, the framework comprises a ring with radially projecting rails each with a kink, which encompasses the upper edge of the protective pane. A cooking container or a wok can be used in the ring.

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 of the invention generates enough heat energy to create wok hei. The multifunction gas burner of the invention produces an open flame (gas) with a power from about 10 kW. 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.

Advantageously, the multifunction gas burner can be converted quickly and easily into a cooker, in particular a wok fireplace. Thus, the means for supporting a cooking vessel comprises a straight bar member and an angled bar member, the straight bar member being adapted to be received in one of the slots, the angled bar member being adapted to partially support a cooking vessel. The means for supporting a cooking container can simply be inserted into the cracks around the burner area with their straight rod elements. If the obliquely angled rod elements face each other towards the center of the burner area, they together form a support for accommodating a cooking container or a wok.

According to a preferred embodiment, it is provided that for the 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 a particularly preferred 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. Particularly preferably, the device also has at least one first coupling element in the form of a magnetizable and/or magnetic surface belonging to the device and, on which at least one second coupling element in the form of a magnet of a means with a flat element for receiving or fixing pieces of food to be cooked or grilled can be attached by means of a magnet connection.

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.

The thermal insulation zone in the edge area of the burner area advantageously prevents the device and the housing of the multifunction burner from overheating. A thermal cal decoupling is realized by spacing or isolation. 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.

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.

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. Essentially, the device forms a plane that is placed on top of the housing. The level can be grooved and/or corrugated. In a further embodiment, the device is essentially wok-like and/or paraboloidal and/or hollow-spherical. In a further alternative, the device can be integrally formed as at least one essentially horizontal plane of the housing, in particular as the upper side of the housing.

The burner area comprises a first combustion bed with a first tube with first gas outlets and optionally a first combustion bed made of a first ceramic for a first firing stage and optionally a second combustion bed with a second tube with second gas outlets and/or a second combustion bed made of a second ceramic for a second firing stage, wherein the first and the second tube and the first firing bed support made of the first ceramic and the second firing bed support made of the second ceramic each have a connection to a gas connection, in particular a gas bottle.

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 side by side in one Be arranged plane or the second combustion bed surrounds the first combustion bed in a circular or polygonal manner 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.

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.

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 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 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.

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

It can be provided that the multifunction gas burner in one embodiment a) a gas fireplace, b) a gas grill, in particular for grilling or smoking items to be cooked or grilled, such as fish, potatoes, vegetables or meat products, or c) a wok. So it is preferred if 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 to be cooked and a wok fireplace with its high temperature in the combustion area. Different firing levels can be set. Adequate thermal insulation of the device and the housing of the multifunction gas burner is provided for all firing stages. In particular, the multifunction gas burner has a modular structure. In order to convert the multifunction gas burner from a gas fireplace into a grill or cooker, the protective disc can be completely removed from the gaps. The protective pane can be designed in one piece or in several pieces.

Likewise, the subject of the invention is the use of at least one means with a flat element for receiving or fixing pieces of food to be cooked or grilled, preferably a means with a flat element and a second coupling element fixed to the flat element via a connecting piece, with a multifunctional gas burner with a housing , in particular a gas grill, comprising the device according to the invention, which forms at least part of a substantially horizontal plane of the housing, and wherein the device comprises 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, 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, and the device has at least one first coupling element, on which at least a second coupling element of the means - or also called the coupling element of the means - with a flat element for receiving or fixing of items to be cooked or grilled is attached by means of a connection, the connection being selected from plugging, snapping, screwing, clamping and/or magnetic connection. It is preferred if the flat element of the means for receiving or fixing pieces of food to be cooked or grilled is pivoted in the direction of the burner area, i.e. in particular the second coupling element is fixed to the flat element via a connecting piece provided with a (ball) joint. For plugging in, at least a second coupling element—or the coupling element of the means according to claim 8—can be designed such that it encompasses at least a first coupling element of the device and can be fixed to it. In one embodiment, a first coupling element can be an outer peripheral edge of a storage area of the device, onto which at least one second coupling element can be attached.

Conventional clamps such as crocodile clamps, foldback clamps, screw clamps, spring clamps, tongue clamps, insulation displacement clamps, magnetic clamps or other conventional clamps with combined functions of a clamp and magnetic support can be used for clamping. Thus, the second coupling element of the means - or the coupling element of the means - include the aforementioned clamps. The at least first and second coupling element can have a Luer lock coupling or any other conventional coupling for latching. Furthermore, connections are preferred, in particular as a first and/or second coupling element—or as a coupling element of the means—for latching by means of a snap connection. The coupling elements can thus include snap connections. The snap connections can be selected from resilient hooks, peripheral resilient grooves or bulges and/or resilient overlapping surfaces. In a further embodiment, the snap connection can be combined with a screw connection for locking the position of the means with a planar element.

Particular preference is given to using at least one means with a flat element for holding or fixing items to be cooked or grilled with a multifunctional gas burner with a housing comprising a device which includes a thermal insulation zone surrounding the burner area, so that the device and optionally the housing are thermally decoupled from the Are burner area, wherein preferably the means comprises a magnet which is attached to a magnetizable and / or magnetic surface belonging to the device.
