Description

The invention relates to a cooking appliance having a cooking chamber which can be subdivided into a plurality of climate zones which are connected openly, according to the preamble of claim 1.

Various approaches for adjusting the spatial climate distribution in the cooking chamber of a cooking appliance are disclosed in the prior art. For example, in the DE 38 79 368 T2 describes a parameter control system in an oven, with the particular temperature, humidity and / or volumetric flow rate can be controlled as a parameter.

So is out of the DE 199 44 265 C2 a cooking appliance known in which the cooking chamber atmosphere is circulated through a fan past a plurality of baffles through the cooking chamber of the cooking appliance. The baffles are arranged in the vicinity of two opposing cooking chamber walls, parallel to insertion levels for food support. By a controllable orientation of the baffles as uniform as possible, laminar flow of the cooking chamber over each food support to be achieved. The spatial uniformity of a cooking process is further enhanced by the fact that the flow direction of the cooking chamber atmosphere is periodically reversible together with the direction of rotation of the fan.

In the DE 1 206 824 A is a deck oven with a plurality of Luftleitgliedern described laying down the floors, in which a reversal of the flow direction of a baking atmosphere is achieved by changing the rotational speeds of two communicating arranged outside the floors blowers. Together with the two blowers ensures a central arrangement of a combustion chamber and steam jets, both also outside the floors, for the generation of a moist baking atmosphere, which is on the Luftleitglieder certain guide channels in the individual floors of the oven and discharged.

In the DE 90 07 085 U1 a cooking appliance is described, the cooking chamber is divided by intermediate floors in three mutually arranged cooking levels. By a separate control of a bottom heat, a top heat and a steam generator with at least two separate steam supplies can produce different climates in a cooking chamber, such. For example, in a lower cooking level temperatures of about 100 ° C, in an upper Garebene temperatures of about 200 ° C and in a closed vessel in a middle Garebene temperatures of about 300 ° C.

The disadvantage is in the in the DE 90 07 085 U1 described cooking appliance that each cooking zone is designed only for cooking in a predetermined and small temperature range. In addition, the climatic separation of the Garzonen by the use of an additional, closed vessel is very expensive.

The DE 103 01 131 B3 discloses a Dampfgargerät with at least two vertically successive Garraumabschnitten, wherein a steam inlet opening are arranged only in a single upper cooking chamber section and a steam outlet opening only in a single lower Gar- space section.

In the generic EP 1 275 333 B1 and the parallel to it DE 101 32 581 A1 discloses a steam cooker, which is divided by cooking space divider into several cooking areas. Each cooking area is associated with steam inlets, steam outlets and temperature measuring devices. The cooking zone temperature can be controlled by changing the steam flow rate at the respective steam inlets and steam outlets depending on the measured cooking zone temperature. In particular, the cooking of several cooking classes is provided, which differ in their cooking time. By adjusting the cooking temperature to the cooking class an identical cooking time for each food to be achieved in each cooking area to avoid opening the oven door during the cooking process.

A disadvantage of the in the EP 1 275 333 B1 cooking appliance described is that air-impermeable cooking space divider or baking trays are needed for the climatic separation of the cooking areas. The use of rust or other air-permeable food carriers is therefore not possible.

In the non 1 925 885 A1 is described that by introducing a hot fluid, in particular from a cooking chamber of a cooking appliance or a heat storage in a hollow accessories, heat on food in the oven are transferred easily and selectively by heat conduction and / or thermal radiation can, so that in the case in which the accessory has a plurality of hollow Gargutträgern different climates in a cooking chamber are enforceable.

However, this also shows from the EP 1 925 885 A1 known cooking appliance with a hollow accessory the disadvantage that certain accessories is necessary to force different Garraumklimata in a cooking chamber. In particular, the use of conventional grates as an accessory is not to several climates in a cooking chamber.

Also found in the prior art continuous ovens for continuous Baking operation with several spatially separate climatic zones, in which the dough is not stationarily positioned in the oven, but is transported via a conveyor or a conveyor belt through the oven. In the DE 695 09 613 T2 is disclosed such an oven, which consists of several coupled together oven segments. By means of a conveyor system, the dough pieces pass successively through the different oven segments, in which the temperature and the humidity of the oven atmosphere are each independently adjustable.

In the DD 230 979 A3 is also a continuous oven disclosed. The baking chamber of this oven consists of several baking zones arranged one behind the other, whose temperature can be adjusted separately. In addition, the moisture content in the baking atmosphere can be regulated in each baking zone.

A disadvantage of the two previously described continuous baking or cooking appliances is that simultaneous cooking of different types of food is not possible.

It is therefore the object of the present invention to develop the generic cooking appliance in such a way that it overcomes the disadvantages of the prior art. In particular, a box-saving and compact cooking appliance is to be provided, which enables simultaneous, food-specific cooking of different types of food when using any type of food supports.

This object is achieved in that the flow rates of each steam-air mixture in the cooking chamber are adjustable so that a flow through the cooking chamber along a plurality of substantially horizontal and / or parallel flow paths, substantially without mutual interference of the climates in the climates , is enforceable, and the climate, determined by at least the temperature, the humidity and the flow velocity of the vapor-air mixture, for each climate zone individually controllable or regulated.

It is preferred that the device for generating and for the guidance of the steam-air mixtures comprises at least one steam generating device, a plurality of steam supply means, at least one steam discharge means, at least one means for generating a flow, a plurality of Strömungsreguliereinrichtungen and at least one heating device and / / or is in operative connection with a control or regulating device.

Furthermore, it can be provided according to the invention that the steam generating device comprises a steam generator.

Furthermore, the invention proposes that the steam supply device comprises at least one steam inlet, preferably in each case with one actuator per climate zone, in particular in the form of a valve flap.

It can also be provided that the steam removal device comprises at least one fan or at least one pump, preferably with a vent pipe, and / or at least one steam outlet, preferably in each case with one actuator per climate zone, in particular in the form of a valve flap.

The invention further proposes that the flow-generating device comprises at least one fan or at least one pump, wherein preferably each fan and / or at least one opening, in each case an actuator, in particular in the form of a valve flap, per climate zone and / or in each of the two includes opposite cooking chamber walls.

Preferred embodiments of the invention are also characterized in that the flow control device outside the cooking chamber at least one substantially pressure-tight closed guide channel, preferably at least two such guide channels, from a cooking chamber wall to an opposite cooking chamber wall, in particular for enclosing the cooking chamber, and at least one continuously variable impeller.

It can be provided that a multiplicity of openings is provided in at least one cooking chamber wall for each climate zone, wherein the number and / or arrangement of the openings is selected in particular in such a way that they produce as uniform a flow as possible of the respective steam-air system. Ensuring mixtures within the climatic zones along a plurality of substantially horizontal and / or parallel flow paths.

Further embodiments of the invention are characterized by at least one sensing device, comprising at least one temperature sensor, at least one moisture sensor and / or at least one flow velocity sensor, preferably in operative connection with the control or regulating device.

It can be provided that at least a portion of the number of openings temperature and / or humidity sensors are mounted.

The invention further proposes that in the cooking chamber ( 1 ) are substantially air-permeable food supports, in particular grates, are inserted.

The invention is therefore based on the surprising finding that a simultaneous cooking of different classes of food can be done within several climates of a cooking chamber, without the cooking chamber is divided by additional climatically insulating partitions. The climatic separation of the climatic zones is rather achieved in that steam-air mixtures in the respective climatic zones with a sufficiently high flow rate along substantially horizontal and / or parallel flow paths through the oven, essentially without affecting the climate in neighboring climates ,

In each climate zone within the cooking chamber, a cooking program desired by a user and / or a cooking program adapted to the respective cooking product can be carried out independently of cooking processes in other climatic zones. Thus, the functionality of several cooking appliances integrated into a single cooking appliance, which leads to the reduction of space requirements at the site and to avoid the cost of further cooking appliances.

Particularly advantageous is the application of the cooking appliance according to the invention in the restaurant operation in the final processing of food "à la carte", where in the flying change as fast as possible gargusspezifischer finishing or warming process must be done for individual, individual items to be cooked.

Optionally, the climatic zones of the cooking appliance according to the invention can be combined to form a cooking space-filling climatic zone, which enables flexible adaptation to the current amount of food to be cooked in the professional catering business.

Further features and advantages of the invention will become apparent from the following description in which a cooking appliance according to the invention is explained by way of example with reference to a schematic drawing. The single figure of the drawing shows a vertical section through the cooking chamber of a cooking appliance according to the invention.

In the cooking appliance according to the invention shown in the figure 100 There is a not shown, closable by a cooking chamber door opening of a cooking chamber 1 parallel to the picture plane. The cooking space 1 is in this embodiment in two climates 2 ⁱ , 2 ⁱⁱ , wherein the dashed line in the figure is a virtual parting plane and no physical barrier between the two climatic zones 2 ⁱ , 2 ⁱⁱ represents.

During the cooking process go through inside the cooking appliance 100 two steam-air mixtures, which are each characterized by their temperature T ⁱ , T ⁱⁱ , moisture F ⁱ , F ⁱⁱ and flow velocity V ⁱ , V ⁱⁱ , two different fluid circuits. Outside the cooking chamber 1 the two fluid circuits are substantially pressure-tightly separated from each other, while within the common cooking chamber 1 communicate openly with each other.

The two fluid circuits are outside the cooking chamber 1 via guide channels 3 ⁱ , 3 ⁱⁱ led. To generate fresh steam comes a steam generator 10 used, with two steam inlets 11 ⁱ , 11 ⁱⁱ fresh water vapor in the guide channels 3 ⁱ , 3 ⁱⁱ , wherein the amount of injected steam for each climate zone 2 ⁱ , 2 ⁱⁱ individually through valve flaps 12 ⁱ , 12 ⁱⁱ in the steam inlets 11 ⁱ , 11 ⁱⁱ can be regulated.

If the humidity F ⁱ , F ^{ii is} too high, excess amounts of steam may be released via steam exhaust 22 ⁱ , 22 ⁱⁱ from the two guide channels 3 ⁱ , 3 ⁱⁱ by means of an external blower 20 be sucked off. The amount of vapor to be extracted becomes for each climate zone 2 ⁱ , 2 ⁱⁱ via valve flaps 21 ⁱ , 21 ⁱⁱ regulated.

The temperature T ⁱ , T ^{ii of} the respective steam-air mixture is in each case via a heating device 30 ⁱ , 30 ⁱⁱ within the guide channels 3 ⁱ , 3 ⁱⁱ set. So is a separate temperature control for each climate zone 2 ⁱ , 2 ⁱⁱ possible.

The steam-air mixtures with the temperatures T ⁱ and T ⁱⁱ and the humidities F ⁱ and F ⁱⁱ are in the cooking mode via two separate impellers 50 ⁱ , 50 ⁱⁱ accelerated to the flow velocities V ⁱ and V ⁱⁱ .

The named elements 12 ⁱ , 12 ⁱⁱ , 21 ⁱ , 21 ⁱⁱ , 30 ⁱ , 30 ⁱⁱ , 50 ⁱ , 50 ⁱⁱ for controlling the supply of live steam and the suction of excess steam, ie the moisture F ⁱ , F ⁱⁱ , for controlling the temperature T ⁱ , T ⁱⁱ and the flow velocity V ⁱ , V ⁱⁱ are connected to an electronic control unit, not shown of the cooking appliance 1 in connection. Furthermore, sensors can be provided for targeted regulation to target values for the climate parameters T ⁱ , T ⁱⁱ , F ⁱ , F ⁱⁱ , V ⁱ , V ⁱⁱ .

The guide channels 3 ⁱ , 3 ⁱⁱ are each at air-permeable openings 60 ⁱ , 60 ⁱⁱ , 62 ⁱ , 62 ⁱⁱ coupled in two opposite cooking chamber walls. The blower wheels 50 ⁱ , 50 ⁱⁱ and the guide channels 3 ' . 3 '' ensure that the steam-air mixtures are on one side of the cooking space 1 over openings 60 ⁱ , 60 ⁱⁱ or 62 ⁱ , 62 ⁱⁱ in the respective climatic zones 2 ⁱ , 2 ^{ii be} blown while on the opposite side of the cooking chamber 1 the steam-air mixtures from the appropriate climatic zones 2 ⁱ , 2 ⁱⁱ are aspirated again, through openings 60 ⁱ , 60 ⁱⁱ or 62 ⁱ , 62 ⁱⁱ .

To ensure the most uniform cooking possible of cooking items not shown in the oven 1 To achieve a periodic reversal of the flow direction of the vapor-air mixtures takes place by the direction of rotation of the reversible impellers 50 ⁱ , 50 ^{ii is} also changed periodically. It is preferred that the reversal of the flow direction in the climate zones 2 ⁱ , 2 ⁱⁱ takes place synchronously to possible turbulence in the oven 1 to avoid.

After in the above description of the figures, the two separate fluid circuits outside the cooking chamber 1 have been explained in detail, now the fluid circuits within the cooking chamber 1 described in detail.

About the large number of arranged in opposite cooking chamber openings 60 ⁱ , 60 ⁱⁱ , 62 ⁱ , 62 ⁱⁱ , the steam-air mixtures are periodically in the climatic zones 2 ⁱ , 2 ⁱⁱ blown and sucked. Here are the two steam-air mixtures in the oven 1 open to each other. A separation of the fluid circuits in the two climatic zones 2 ⁱ , 2 ⁱⁱ in the oven 1 is achieved in that the vapor-air mixtures have a sufficiently high flow velocity V ⁱ , V ⁱⁱ , with minimal mutual interaction along substantially horizontal and parallel flow paths through the cooking chamber 1 to stream.

Depending on the flow velocity V ⁱ , V ⁱⁱ and the width L of the cooking chamber 1 may have a transit time T _trans ⁱ = L / V ⁱ for the upper climatic zone 2 ⁱ and a transit time T _trans ⁱⁱ = L / V ⁱⁱ for the lower climate zone 2 ^{ii be} defined. After entering the oven 1 resides a volume unit of an air-steam mixture accordingly for the respective transit time in the oven 1 , Due to diffusion, a temporary exchange of heat and moisture inevitably takes place between the neighboring climatic zones 2 ⁱ , 2 ⁱⁱ instead. In order to avoid, at least reduce, these diffusion effects, the shortest possible transit time is for each climate zone 2 ⁱ , 2 ⁱⁱ preferred. An approximation of the flow velocities V ⁱ , V ⁱⁱ in the climatic zones 2 ⁱ , 2 ^{In this case, ii} is advantageous in order to achieve as horizontal a flow as possible through the cooking chamber 1 to ensure. However, it is also possible to specify a tolerance range for the transit time within which a variation of the flow velocity V ⁱ , V ⁱⁱ for optimizing the cooking processes, in particular when carrying out a cooking program, in the two climatic zones 2 ⁱ , 2 ^{ii is} admissible.

Further, the openings 60 ⁱ , 60 ⁱⁱ , 62 ⁱ , 62 ^{ii arranged} within the opposite cooking chamber walls so that, on the one hand, a substantially horizontal flow path in the cooking chamber 1 and on the other hand the lowest possible interaction between the steam-air mixtures in the climatic zones 2 ⁱ , 2 ^{ii is} achieved. At least a part number of the openings 60 ⁱ , 60 ⁱⁱ , 62 ⁱ , 62 ⁱⁱ are moisture and temperature sensors, not shown, for measuring the temperature T ⁱ , T ⁱⁱ and the humidity F ⁱ , F ⁱⁱ attached. In addition, at least one not shown flow velocity sensor per climate zone 2 ⁱ , 2 ⁱⁱ measurement of the flow velocities V ⁱ , V ^{ii of} the respective steam-air mixtures provided.

The humidity, temperature and flow rate sensors are connected to the electronic control unit of the cooking appliance 100 in connection. The electronic control unit makes it possible to control the temperature T ⁱ , T ⁱⁱ , the humidity F ⁱ , F ⁱⁱ and the flow velocity V ⁱ , V ^{ii of} the steam-air mixture in the respective climatic zones 2 ⁱ , 2 ⁱⁱ as a function of the values measured on the moisture, temperature and flow velocity sensors.

When controlling the climate for a climatic zone, it is also envisaged to take into account the measured temperature, humidity and / or flow velocity values of the neighboring climate zone in order to prevent any exchange of heat and / or moisture between the climatic zones or any turbulences or turbulences of the steam. Counteract air mixtures in the cooking chamber.

Thus, within a cooking chamber 1 a cooking appliance 100 several climates 2 ⁱ , 2 ^{ii are} realized for the simultaneous individual cooking of different types of food. The temperature T ⁱ , T ⁱⁱ , the humidity F ⁱ , F ⁱⁱ and the flow velocity V ⁱ , V ⁱⁱ may be in any climatic zone 2 ⁱ , 2 ^{ii be} adapted to the particular food, for example by entering into a not shown control panel of the cooking appliance by a user. Likewise, the sizes mentioned can be changed in time during the cooking process according to the specifications of an automated cooking program, as is known from the prior art.

Due to the climatic separation of the climatic zones 2 ⁱ , 2 ⁱⁱ are made to the nature of the Gargutträger not shown in the figure no claims. Such a food support, typically via guide elements in the cooking chamber 1 can be inserted, can therefore be an air-permeable rust or a baking sheet.

When using a baking tray, the need for the shortest possible transit time in the oven is relativized, since diffusion processes between the climates 2 ⁱ , 2 ^{ii be} prevented by one or more baking sheets at least to a large extent. In a further embodiment of the invention, this effect can be detected by measuring the spatial distribution of the temperature and the humidity at the cooking chamber walls that has changed after insertion of the baking sheet. In this case, the maximum permitted transit time for the affected climatic zones can be increased, so that a greater tolerance range of the transit time is available for a regulation of the cooking process.

In a further embodiment, the generation and control of the flow of the vapor-air mixtures can be carried out by a single impeller connected to both guide channels 3 ⁱ , 3 ⁱⁱ is related. As a result, a synchronous flow reversal in the alternating flow mode and an identical flow velocity (V ⁱ = V ⁱⁱ ) of the vapor-air mixtures inevitably. However, additional guide elements would have to be provided in this case for the effective separation of the fluid circuits when passing through the impeller.

It should be noted at this point that the cooking appliance according to the invention 100 structurally is not limited to two climatic zones. While the top and bottom arranged in the oven climate zones according to the case shown in the figure with such guide channels are in communication, at least partially above and below the cooking chamber 1 run, can be connected in the cooking chamber intermediate, other climatic zones, each with such a guide channel, which is guided past the cooking chamber at a constant height outside the cooking chamber.

The features of the invention disclosed in the foregoing description, in the claims and in the drawings may be essential both individually and in any combination for the realization of the invention in its various embodiments.
