Definitions

  • the invention concerns a cooking unit with a heating surface for warming up food.
  • the invention is based on the problem to provide a particularly suitable cooking unit with a preferably relatively low noise development, avoiding in particular an odour nuisance to the users as reliably as possible.
  • the cooking unit comprises a heating surface for warming up food, wherein the temperature of the heating surface may be increased to in particular more than 100°C.
  • the food is laid down directly on the heating surface, it is, however, also possible to put the food in an additional container, such as a pot or a pan and to place this container on the heating surface.
  • the container can also substantially form the heating surface.
  • means are arranged which are designed for providing a first and a second air flow.
  • the means for providing the first air flow and the means for providing the second air flow can be arranged in separate housings or the like. Particularly preferably, the means are mounted within one single housing.
  • the means for providing the second air flow are in particular located above the means for providing the first air flow, the second air flow being situated at least at a distance above the first air flow.
  • the air flows are of a flat form.
  • each air flow passes over the heating surface, shielding the latter in this way against the environment of the cooking unit.
  • a space is formed within which any odours or floating particles exhaled by the food are retained. If these particles approach the first air flow, they will be carried along and accelerated in the direction of movement of the air of the first air flow. Should, nevertheless, such a particle get through the first air flow, it will be carried off by the second air flow, so that practically no particle will penetrate the first and second air flows.
  • the first air flow or the second air flow is sucked off by means of an extraction device arranged above the heating surface.
  • the particles possibly present are also absorbed by the extraction device.
  • both the first and the second air flow are sucked off by the extraction device.
  • the cooking unit is of a space-saving design.
  • the respective second air flow is directed towards the extraction device. In other words, the direction of movement of the air from the means to the extraction device is substantially straight-lined.
  • the heating surface is rectangular and along one side of the rectangle, the means for providing the, or each, air flow are arranged.
  • the extraction device is located on the side of the heating surface opposite these means.
  • the extraction device is mounted on a wall located there.
  • the cooking unit With the cooking unit, it is possible to prepare inside a room even food producing great exhalations, such as, for example, fish or other seafood. Due to the separation of the heating surface from the environment, the environment is free of odour nuisance, while the food is, nevertheless, visible for persons. Furthermore, it is possible to treat the food while it is being warmed up, for example to spice it up or turn it. Due to the generation of the air flow with the help of the means for providing the, or each, air flow and the thus substantially immediate shielding of the heating surface, the food can be prepared substantially immediately after putting the cooking unit into operation, without odours escaping into the environment.
  • further air flows can be provided, in order to achieve, if needed, an even better shielding of the heating surface from the environment of the cooking unit.
  • the distance between the first air flow and the second air flow is, for example, between 1 cm and 10 cm and may vary along the two air flows. In this way, a relatively reliable shielding of the environment from cooking odours is guaranteed, the cooking unit having compact dimensions. Furthermore, the two air flows are separated, which reduces turbulences and mutual interferences of the air flows. The distance between the two air flows is in particular 2 cm.
  • the distance between the first and second air flows is one fortieth of the diameter of the in particular circular heating surface, plus 10mm.
  • the distance will be 15 mm, if the diameter of the heating surface is 20 cm, 25 mm for a diameter of 60 cm, and 35 mm for a diameter of 100 cm.
  • the first air flow and the second air flow include in the area of the means an angle of less than 20°.
  • the air flows substantially extend flatly and the angle included by the two planes within each of which one of the air flows lies, is 20° or less.
  • the angle is less than 10° and the direction of spread of the two air flows is, for example, parallel.
  • the two planes are parallel, it would, however, also be imaginable that the direction of spread of one of the air flows is substantially opposed to the other. It is particularly preferred that the two air flows are blown in the direction of the extraction device and provided at an angle which is smaller than 20°.
  • the cooking unit having a heating surface for warming up food included in the edge region of the heating surface means providing a first air flow.
  • the first air flow is sucked off by means of an extraction device located above the heating surface.
  • the extraction device can be arranged both centrically with, and offset against, the heating surface. At least, the heating surface and the food located, for example, thereon, are separated by means of the air flow from the environment of the cooking unit.
  • the speed at which the air of the first air flow moves is lower than 6 m/s, the speed being preferably higher than 1 m/s. In this way, a relatively low noise generation of the cooking unit is guaranteed, with the environment of the cooking unit being, nevertheless, olfactorily shielded against the food.
  • the air speed of the first or second air flow is lower than 4 m/s and in particular lower than 3 m/s.
  • the air speed is higher than 2 m/s.
  • the air speed is 2.65 m/s.
  • the thickness of the curtain-like first or second air flow is between 3 mm and 7 mm.
  • thickness one understands here in particular the smallest extension of the air flow normal to its direction of spread.
  • a thickness of 5 mm of the respective air flow is particularly suitable. Due to these dimensions, the cooking unit can be built in a relatively space-saving manner, with the shielding being, nevertheless, reliable.
  • the air of the first or second air flow, sucked off by means of the extraction device is returned to the means and used for a repeated creation of the air flow.
  • the air is returned, for example, inside the cooking unit by means of tubes or hoses.
  • the extraction device is followed by an intake system connected directly or via another system to a fan, in such a way that the air is passed from the extraction device to the fan.
  • the air is sucked in by means of the fan, and expediently, the fan generates an underpressure, by means of which the extraction device is operated.
  • the fan generates an overpressure on the side of the fan which is opposite the extraction device, said overpressure moving the air to the means and providing the respective air flow.
  • the fan is advantageously operated by means of an electric motor and comprises in particular a fan wheel having a diameter between 20 cm and 30 cm.
  • the diameter is 25 cm.
  • the rotational speed of the fan wheel, during operation of the cooking unit preferably lies between 800 rpm and 2800 rpm. This guarantees a low noise development of the fan.
  • the fan is, for example, sound-insulated by means of additional elements.
  • the air between the extraction device and the means is cleaned by means of a filter system.
  • the filter system is preferably located between the intake system and the fan, it can, however, also be mounted in another location.
  • the filter system is removable and includes, for example, a first filter and a second filter, the first filter being arranged in front of the second filter, viewed in the direction of movement of the air.
  • the first filter is washable and serves for catching and retaining fat residues of the prepared food, which are in the air.
  • the second filter is a carbon filter, by means of which odours and other residues are removed from the air.
  • the washable first filter prevents a pollution of the carbon filter caused by the fat residues and increases the operating time of the filter system.
  • a substantially closed system is realized. Between the extraction device and the means for providing the, or each, air flow, further elements can be arranged. The order of the elements located between them may also vary.
  • the substantially closed system enables an integration of the cooking unit into existing kitchens, dining rooms or the like, without having to change the construction of the rooms to guarantee a supply of the cooking unit with fresh air for the air flow(s).
  • additional intake systems and blowoff systems can be provided, so that a certain share of the first or second air flow consists of fresh air continually taken from the environment, with the same share of used air being liberated into the environment.
  • the intake system has the shape of a hollow cylinder, the air being guided inside the intake system.
  • the intake system is a flexible hose or a tube.
  • the inner diameter of the hollow cylinder lies between 7 cm and 10 cm. Particularly preferably, the inner diameter is 8.4 cm. In this way, a sufficiently large air flow rate through the intake system can be realized, without the air speed being relatively high. This will advantageously reduce the noise development. In addition, the space required by the intake system will be low.
  • the intake system suitably includes a number of tubes aligned in parallel to each other, which are in particular arranged inside the hollow-cylinder shape of the intake system or which substantially form the intake system.
  • the division of the intake system into a multitude of tubes avoids turbulences inside the sucked-off air, which advantageously reduces the noise disturbance.
  • the tubes are relatively long and have a relatively small diameter.
  • the intake system comprises at least ten such tubes, which have a diameter in particular between 1 cm and 3 cm.
  • the length of the tubes lies during operation of the cooking unit between 10 cm and 30 cm.
  • the heating surface is of a circular shape and has in particular a diameter between 30 cm and 50 cm, a diameter of substantially 40 cm being particularly suitable.
  • a surface for the preparation of food is provided, which is sufficiently large for all practical purposes, and the warming-up of the heating surface requires relatively little energy. Furthermore, these dimensions assure a manageable handling of the cooking unit.
  • the heating surface comprises in particular a number von partial heating surfaces, expediently two or three partial heating surfaces, and is in particular composed of these.
  • Each partial heating surface can separately be removed from the cooking unit.
  • the cooking unit can be both disassembled and assembled in a relatively simple manner, and individual partial heating surfaces can be removed for being cleaned.
  • each partial heating surface has the shape of a segment of a circle.
  • the heating surface is heated by means of an induction device.
  • the heating surface is made of a magnetic material or at least contains such material.
  • the heating surface consists of iron or has a core containing iron.
  • a current-carrying coil is arranged below the heating surface, by means of which a magnetic alternating field is generated. This magnetic field in turn induces eddy currents in the heating surface, which heat up the heating surface. This in turn warms up the food for its preparation.
  • the induction device makes it possible to specifically warm up the food to a certain temperature, in particular to up to 250°C, with a relatively low power requirement.
  • the heating surface could be heated by an electric resistor.
  • the electric resistor having a relatively high resistance value, is in thermal contact with the heating surface and is arranged in particular below said heating surface, for example in a meander, spiral or circular shape. Expediently, the longitudinal extension of the resistor is relatively great. If a relatively high electric voltage is applied on the electric resistor, the latter will warm up. Due to the thermal coupling with the heating surface, the heating surface is heated up. In this way, in particular temperatures of the heating surface of up to 500°C can be realized, the power consumption of the electric resistor lying between 1 kW and 2 kW. It would, however, also be imaginable that the heating surface has the shape of a grate and is heated by means of coals or gas flames arranged therebelow.
  • the means for providing the first or second air flow are designed in the manner of nozzles.
  • the respective air flow is directed by the preferably nozzle-like means in the direction of the extraction device.
  • the means have in particular an outlet opening and an inlet opening, the air escaping through the outlet opening towards the air flow and the air being guided to the means through the inlet opening.
  • the inlet opening is pneumatically connected with the fan.
  • the outlet opening is smaller than the inlet opening, which leads to an increased air speed of the respective air flow.
  • the means for providing the, or each, air flow surround the edge of the heating surface substantially completely.
  • the means for providing the, or each, air flow are immediately adjacent to the edge of the heating surface or are located at a distance from the edge of the heating surface.
  • the outlet openings of the means are, for example, hole-shaped and distributed along the edge of the heating surface.
  • the outlet opening of the means has the shape of a slot and surrounds the heating surface substantially in a ring-shaped manner.
  • the width of the slot corresponding in particular to the thickness of the air flow provided by means of this slot, lies, for example, between 4 mm and 6 mm.
  • two such slots are arranged one above the other, and the first air flow is provided by means of one of the slots and the second air flow is provided by means of the other slot.
  • the cooking unit comprises a device, in the following referred to as tower, which projects from the plane of the heating surface and is arranged in the middle of the heating surface.
  • the in particular round heating surface has a central recess, the tower being located in the recess.
  • the longitudinal direction of the tower suitably extends substantially normal to the heating surface.
  • the extraction device is attached to the tower, part of the tower expediently forming the extraction device.
  • the extraction device includes a slot-shaped inlet opening, through which the first or the second air flow are sucked off into the tower.
  • the inlet opening surrounds the upper area of the tower, for example, in a ring-shaped manner.
  • the tower is designed in a rotationally hyperbolic shape, the tower being advantageously formed by the upper area of the hyperboloid shape.
  • the diameter of the tower increases with increasing distance from the heating surface.
  • the tower has substantially the shape of a scaled-down, upside down cooling tower of a power plant. Due to the fact that the cross-section of the tower is larger at a distance from the heating surface than in the cross-sectional area close to the heating surface, the tower projects over the heating surface. In this way, it is possible to suck off the first or second air flow simply and completely by means of the extraction device installed there, having, nevertheless, a relatively large surface available for preparing the food.
  • the distance of the extraction device from the heating surface can be changed.
  • the cooking unit can be adapted, for example, to the circumstances prevailing at the moment, such as any wind blowing, when the cooking unit is used outdoors.
  • the tower, to which the extraction device is attached can be changed or shifted along its longitudinal extension.
  • the tower can be telescoped and in particular, the upper area of the tower can be put into contact with the heating surface or at least approached to it relatively closely. In this way, a space-saving storage of the cooking unit is assured.
  • it is possible, in telescoped state to place objects on the surface of the upper area of the tower, which is preferably plane and expediently flush with the environment of the cooking unit.
  • a table grill is equipped with such a cooking unit, said table grill being in particular portable.
  • table grill one understands here a grill which can be put on a dining table and can be removed after use.
  • the air is guided within a closed circulation.
  • it is, therefore, expediently, only necessary to supply the cooking unit and/or the means providing the, or each air flow with electric power, which enables a fast installation and removal of the table grill.
  • two air flows are used.
  • the two air flows are situated in the area between the two zones.
  • one of the air flows suitably completely limits one of the zones.
  • a border area is formed, extending between the first and second zones. Therefore, to get from the first zone into the second zone, the two air flows and the border area have to be passed.
  • the two air flows are designed like a curtain or a wall.
  • the direction of movement of the air inside the two air flows is parallel and their respective speeds are, for example, identical.
  • the distance between the two air flows lies between 1 cm and 10 cm.
  • additional air flows can be used, which are substantially parallel to the first two air flows and are also situated between the two zones. In this way, the efficiency of the olfactory shielding is increased.

There, the odours 28 are sucked off with the air of the first air flow 30 through the extraction slot 18a of the extraction device 18.

  • the width of the slot of each of the nozzles 32a, 32b is 5 mm.
  • the first air flow 30 and the second air flow 34 also have a thickness of 5 mm in the area of the means 32.
  • the cross-section of the slot-shaped outlet openings of the two nozzles 32a, 32b is smaller than the cross-section of the air guiding system 42. Therefore, to assure that the speed of the air flows 30, 34 is equal to 2.7 m/s, a lower air speed is necessary inside the air guiding system 42. Therefore, relatively little whirls arise inside the air guiding system 42, so that the air is moved practically noiselessly inside the air guiding system 42. Furthermore, due to the relatively low air speed inside the air guiding system 42, the fan 40 can be operated at a relatively low rotational speed, which also reduces the noise level emitted by the cooking unit 4.

  • the extraction slots 18a, 18b can also be shifted relative to the heating surface 10. This changes the distance of the extraction slots 18a, 18b from the heating surface 10.
