The cooking pot comprises in the pan: a first grid in which the storage rack is placed; a heating device; a second grid in which the heating device is placed; and a partition arranged between the first grid and the second grid. Summary of the invention

[0007] The object of the present invention is to at least partially overcome the disadvantages of the prior art and to provide a cost-effective solution, in particular for the domestic sector, for simultaneously and individually steaming different foods in a small space without affecting each other's taste.

[0008] This object is achieved according to the features of the independent claim. Preferred embodiments can be found in particular in the dependent claims.

[0009] This object is achieved by a steam cooking device, which has:

[0010] a steam treatment space which can be divided into at least two subspaces by at least one room divider,

[0011] at least one room divider which is designed to divide the steam treatment room or a sub-room thereof into two sub-rooms in a gas-tight manner,

[0012] - Wet steam generator,

[0013] a steam supply channel which is designed to conduct the steam generated by the wet steam generator into the steam treatment space,

[0014] at least one steam discharge channel which is designed to discharge steam from the steam treatment space,

[0015] in,

[0016] The steam supply channel is designed to conduct the steam generated by the wet steam generator into each of the subspaces.

[0017] The advantage of the steam cooking device is that the user can divide the steam processing space into two or more subspaces by at least one space divider as required. This enables the simultaneous and separate processing of various foods with steam in a small space. The airtightness not only achieves spatial separation of the separated subspaces, but also achieves gas environment separation ( Trennung), and thereby prevent the sub-spaces from influencing each other's taste. In addition, different gas environment conditions in the sub-spaces (e.g. in terms of air humidity, air temperature, flow rate, etc.) can be easily realized in this way in terms of structural design. In addition, compared with the use of undivided steam treatment spaces, the energy requirement and / or cleaning expenditure is lower, and faster heating times are also achieved. Since steam generation is achieved for multiple sub-spaces by a common wet steam generator, steam treatment can also be implemented cost-effectively.

[0018] One modification is that the steam cooking device is a domestic steam cooking device. The steam cooking device can be an independent steam cooking device or a combined device, such as an oven and / or a microwave device with a steam processing function (such as so-called "additional steam").

[0019] The steam processing space is provided for accommodating cooking objects and applying steam thereto by the steam cooking device when necessary.

[0020] When the steam treatment space is closed, the two or more subspaces are gas-tight and therefore separated from each other in terms of the gaseous environment, i.e. no steam is exchanged between them, in particular during the steam treatment process. The two subspaces are separated from each other in a gas-tight manner, which in particular also includes that they are separated from each other in a liquid-tight manner.

[0021] By inserting a space divider, the space to which steam can be applied (i.e., the steam treatment space or its subspace) can be divided into two subspaces to which steam can be applied respectively, that is, in an airtight manner, thereby preventing the exchange of gaseous environments between the two subspaces and the exchange of liquids (e.g., condensates). The two subspaces can be separated from each other in a sealed manner, i.e., in terms of gas and liquid technology, by the space divider when the steam treatment space is closed. This can be achieved in such a way that at least the steam treatment space as a whole is divided into a first subspace and a second subspace by the space divider. If provided for this purpose, another space divider can be added, which further divides the first subspace into two subordinate subspaces, and so on. In general, the steam treatment space can be divided into n+1 subspaces separated from each other in an airtight manner by n space dividers.

[0022] The room divider is in particular plate-shaped, in particular cuboid, and can then also be referred to as a partition.

[0023] The steam that can be introduced into the subspace is generated by a single wet steam generator arranged outside the steam treatment space. The wet steam generator generates wet steam, i.e. steam that can be heated to the boiling point of water or steam generated by boiling. It may still contain water droplets and is therefore called "wet".

[0024] One modification is that at least one SHS steam heater is connected downstream of the steam generator, which is designed to convert the wet steam generated by the wet steam generator further into superheated steam. "Superheated steam" can be understood in particular as steam that has been heated above the boiling point of water, which is also called dry steam or SHS (Super Heated Steam). Superheated steam is so hot that it usually no longer has any water droplets and is therefore also called "dry". The temperature of dry steam is above the boiling temperature of water and can be, for example, up to 200° C., 300° C., 400° C., 500° C., 600° C. or even higher.

[0025] In a modification, the combination of a wet steam generator and at least one SHS steam heater arranged outside the steam treatment space can also be referred to or considered as a (two-stage) steam generator, wherein wet steam is generated in the first stage by boiling water and is converted into superheated steam in the second stage.

[0026] The steam supply channel is designed to conduct steam generated by the wet steam generator (i.e. wet steam or additionally heated superheated steam) into each of the subspaces, which in particular includes: the steam supply channel can be designed to be able to conduct steam, in principle, also simultaneously into each of the subspaces. This does not exclude the following situation, that if necessary, during the cooking process, steam is not applied to at least one of the subspaces in a targeted or controlled manner, wherein the steam cooking device is however designed to apply steam to each of the subspaces when necessary.

[0027] The steam supply channel is configured to guide the steam generated by the wet steam generator into each of the subspaces, which also includes guiding the steam directly from the wet steam generator into each of the subspaces and thus not passing through a plurality of subspaces.

[0028] The steam (and possibly the smoke) located in the steam treatment space or the subspace can escape from the steam treatment space or the subspace before, during and / or after the cooking process through at least one steam exhaust channel. The steam exhaust channel can, for example, lead to the front side of the steam cooking device and / or to a fume extraction device. The escape or exhaust of the steam from the steam treatment space can be achieved by increasing the steam pressure in the steam treatment space and / or by suction (for example with the aid of a fan).

[0029] Generally speaking, the steam processing space can be used for steam processing of cooking items stored therein with or without a space divider.

[0030] In one embodiment, the steam supply channel has a steam inlet connected to the wet steam generator and at least one branch having at least two outlet branches leading to the steam treatment space. This achieves the following advantage: a plurality of spatially separated steam flows can be guided into the steam treatment space in a structurally simple manner. This can be particularly advantageous for applying a high steam throughput even if the spatial regions of the steam treatment space are far apart from one another. Typically, the branch has an inlet branch and at least two outlet branches branching off or diverging therefrom. The steam enters the inlet branch and can flow through the outlet branch in principle.

[0031] One modification is that at least two branches are arranged fluidically one behind the other, so that at least one of the outlet branches of the preceding branch is connected to the inlet branch of the branch that follows fluidically. This branching structure can be cascaded any number of times in principle and allows more than two outlet branches to be provided in a structurally simple and easily variable manner.

[0032] If the steam cooking device is equipped with at least one SHS steam heater, a modification is to arrange the SHS steam heater in terms of fluid technology before at least one branch so that superheated steam can flow through all branches in a particularly cost-effective manner when the SHS steam heater is in operation. A modification is that all outlet branches are equipped with corresponding SHS steam heaters. The following advantage is thus achieved: it is possible to set individually for each outlet branch of the outlet branch whether wet steam or superheated steam should flow from the outlet branch into the processing space or the assigned subspace. A modification is that only a part of the outlet branches is equipped with SHS steam heaters. Therefore, it is advantageously possible to apply only wet steam to at least one subspace and superheated steam to at least one other subspace, or alternatively to apply wet steam or superheated steam, in a still cost-effective manner.

[0033] In one embodiment, at least one branch has a controllable regulating device in order to variably or proportionally regulate the steam flow rate through the outlet branch of the associated branch. This allows the steam flow rate into a plurality of sub-spaces to be proportionally regulated in a robust and structurally simple manner and thus also to specifically regulate the air moisture / air humidity, air temperature and / or flow rate for the respective sub-spaces together with the set heating power of the wet steam generator and, if necessary, the SHS steam heater. The regulating device can be regulated in particular by the steam cooking device, for example, by a motor or an actuator. The regulating device is in particular designed to proportionally regulate the flow cross section of the outlet branch.

[0034] In a modification, the regulating device is an electrically adjustable valve flap, in particular via a motor or an actuator, in particular a pivotable valve flap, wherein the angular position or pivot position of the valve flap determines the flow cross section of the outlet branch. In a modification, the branch is designed as a valve, in particular a proportional valve.

[0035] However, the steam supply channel can in principle also have at least one branch without a regulating device, which can advantageously be implemented particularly cost-effectively.

[0036] Similar to the branched steam inlet channel, the steam outlet channel can also have at least one branch or branch merging portion with a controllable regulating device to variably or proportionally regulate the steam flow through multiple inlet branches. In particular, an outlet branch can then be connected, for example, to a fan.

[0037] One design is that at least one branch has exactly two outlet branches. This can be achieved particularly easily by a Y-shaped pipe. If the branch is equipped with a regulating device, this can also be achieved particularly easily, for example in the form of a Y-shaped valve.

[0038] One embodiment is that the steam supply channel has (exactly one) steam inlet or steam supply opening which opens into all possible subspaces. This embodiment is particularly easy to implement since no branching is required, but only an expansion ("widening") of the steam supply channel is required. The distribution of the steam throughput into the individual subspaces can then be adjusted by positioning or placing the room divider behind the steam supply opening, which may be done manually by the user. Depending on the position of the room divider along the width of the steam supply opening, more or less steam reaches the subspace assigned to the room divider.

[0039] In one embodiment, the steam cooking device is a steam cooking drawer having a drawer that can be moved out of and into a drawer housing. The drawer has a steam processing space. The steam processing space advantageously has a trough-shaped cooking container that can be covered by a lid. The cooking container and the lid, which is placed thereon, in particular in an airtight manner, form the steam processing space. The cooking container can be taken out of the drawer by a user.

[0040] In one embodiment, the cooking vessel has at least one steam inlet opening introduced on the front side or in the wall region of the front side, through which the steam flowing out of the steam inlet channel can enter the cooking vessel, and optionally also at least one steam escape or steam outlet opening introduced on the rear side. This achieves the advantage that a steam / air flow can be generated in a structurally simple manner through the steam processing space or subspace in a targeted manner. The at least one steam inlet opening of the cooking vessel can be connected to the steam inlet channel directly or via at least one additional sleeve integrated into the cooking vessel, the flow confluence of which on the processing space side corresponds to the steam inlet opening.

[0041] In one embodiment, at least at the front and rear side of the cooking vessel there are holding devices for inserting at least one room divider, in particular a partition. This provides the advantage that, when viewed from the front toward the front side, at least two sub-spaces arranged next to one another are provided, to which steam can be applied separately and particularly easily. In a front view, the holding devices can in particular be arranged one behind the other, so that the room divider can be arranged perpendicularly to the front and rear side.

[0042] A modification is that the holding device has an insertion slot on each wall. This has the advantage that the room divider can be inserted into the holding device from above by simple insertion. The insertion slot can be formed, for example, by two vertically oriented ribs arranged next to each other.

[0043] In one embodiment, the cooking vessel has at least two steam inlet openings on its front side which are laterally spaced apart from one another in a front view, and at least one holding device present on the front side is arranged between the steam inlet openings which are spaced farthest from one another (outermost). This advantageously ensures that even the leftmost and rightmost sub-spaces can be supplied with steam.

[0044] In one embodiment, the cooking vessel has at least two steam outlet openings on its rear side, which are laterally spaced apart from one another in a front view, and at least one holding device present on the rear side is arranged between the steam outlet openings which are spaced farthest from one another (outermost). This advantageously ensures that even the sub-spaces formed on the far left and right can be supplied with steam. This advantageously achieves a function or effect of the steam outlet openings which is similar to that of the steam inlet openings.

[0045] For the case where the cooking container has at least two steam input openings spaced apart from each other laterally in the front view at its front side, a particularly advantageous design is that the steam input channel has exactly one Y-shaped branch, which has exactly two outlet branches. This can advantageously be implemented particularly easily, for example by a simple Y-shaped valve. The steam treatment space can then be divided into two subspaces to which steam can be applied separately by the space divider. If the space divider has been inserted into the steam treatment space, the two outlet branches lead to the corresponding subspaces. In particular, each of the two subspaces has a steam input opening and advantageously also has a steam discharge opening. The two steam input openings are arranged on both sides of at least one retaining device mounted at the front side, which ensures that steam can be applied to the two subspaces regardless of the position of the space divider, that is to say even if the space divider can be arranged on a plurality of different retaining devices and therefore at a plurality of different positions.

[0046] A design scheme is that at least one steam exhaust channel is a branched or unbranched steam exhaust channel. This can be advantageously implemented particularly easily. At least one steam exhaust channel has in particular exactly one steam outlet end. If there is exactly one unbranched steam exhaust channel, it can have (exactly one) steam exhaust opening, which merges into all possible subspaces. This design scheme can be implemented particularly easily because no branching is required, but only the expansion ("widening") of the steam input channel is required. Then, the distribution of the steam flow rate entering the steam exhaust channel can be adjusted by positioning or placing the space divider in front of the steam exhaust opening, which is manually performed by the user if necessary. Depending on the position of the space divider connected along the width of the steam exhaust opening, more or less steam will be discharged from the subspace assigned to the space divider. A modification scheme is that the space divider, in particular the partition, has a seal around, that is, at all edge sections. This advantageously and particularly effectively prevents the exchange of air, steam, condensate, etc. between the subspaces separated by it. In the case of a trough-shaped cooking vessel that can be covered by a lid, the plate-like partition can, for example, rest or be placed with its lower edge section on the bottom of the cooking vessel, with its side edge sections on the front or rear side and with its upper edge section on the lid. The seal can, for example, be made of rubber, plastic, ceramic, etc.

[0047] One design solution is that the room divider is designed in a heat-insulating manner. This has the advantage that the thermal influence on adjacent sub-spaces is also reduced. The room divider can be designed in a heat-insulating manner, for example, by being composed of a material with a poor thermal conductivity (e.g. plastic) of sufficient thickness or being filled with a special heat-insulating material.

[0048] In one embodiment, the room divider has at least one electrical heating element. This makes it possible to influence the temperature in one or both sub-rooms separated by it particularly effectively. In a further development, the room divider, in particular a partition, has at least two electrically operated heating elements on each (flat) side, wherein at least one heating element on one side is thermally separated in particular from at least one heating element on the other side. This achieves the advantage that the sub-rooms can be heated individually with particularly low mutual thermal influences. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The above-mentioned characteristics, features and advantages of the present invention and the manner of achieving them can be more clearly understood with reference to the following schematic description of the embodiments explained in detail with reference to the accompanying drawings.

[0052] Figure 3 A steam cooking device is shown in an oblique front view; and

[0053] Figure 4 The steam cooking device is shown in a view obliquely from the rear. DETAILED DESCRIPTION

[0054] Figure 1 A schematic diagram of a drawer 1 of a steam cooking device in the form of a steam cooking drawer 2 is shown in a top view. As indicated by the double arrow, the drawer 1 can be moved horizontally into the drawer housing 3 (see Figure 3 and Figure 4 ) and moved out therefrom, wherein the front panel 4 of the drawer 1 closes the front opening of the drawer housing 3 in the moved-in state.

[0055] The drawer 1 has an electric wet steam generator 5, which is designed to boil water to produce wet steam D. The wet steam generator 5 can be controlled, for example switched on and off, by a control device 6. In particular, the heating power of the wet steam generator 5 can be adjusted by the control device 6, thereby in turn adjusting the volume of wet steam D generated per unit time. Optionally, at least one SHS steam heater (not shown) can be connected downstream of the wet steam generator 5.

[0056] A steam inlet channel 7 is connected to the steam outlet of the wet steam generator 5, which is designed to guide the wet steam 5 generated by the wet steam generator 5 or the superheated steam in the case of a SHS steam heater into a steam processing space 8. The steam processing space 8 is formed here by a trough-shaped cooking container 9 with an open top side and a cover (not shown) that can be placed on the cooking container 9 in an airtight manner, for example, made of glass. The cooking container 9 can be removed by the user in particular. It is used to receive cooking, if necessary, for receiving cooking in a cooking container such as a GN container.

[0057] Furthermore, the steam treatment chamber 8 can be connected or is connected in the installed state to a steam outlet channel 10 which is provided for discharging steam from the steam treatment chamber 8 , for example into the surroundings or into an exhaust system (not shown).

[0058] The cooking container 9 has a plurality of vertically oriented ribs 11 arranged parallel to one another on the inner side of its front side 9v and at the same location of its rear side 9h in the front view, namely six pairs of front and rear ribs 11 arranged parallel to one another here. When the lid is removed or opened, a room divider in the form of a plate-like partition 12 with a rectangular basic shape can be inserted by the user between adjacent rib pairs and can also be removed again. Thus, adjacent rib pairs form a holding device for the partition 12. By means of the six rib pairs exemplified in the present example, the partition 12 can be optionally arranged in one of five positions P1 to P5.

[0059] The edge of the partition 12 is surrounded by a seal 13 (see Figure 3 and Figure 4 ), which seal can be made, for example, of rubber, plastic, ceramic, etc. The partition wall 12 can optionally be designed in a specially heat-insulating manner and / or can optionally have at least one electric heating element 14.

[0060] When the partition 12 is installed and the cover is placed, the steam treatment space 8 is divided into two gas-tight (and therefore also liquid-tight) and separate subspaces 8a and 8b. The distribution volume of the subspaces 8a and 8b can be adjusted by different positions P1 to P5.

[0061] The steam supply channel 7 is designed in such a way that the steam D generated by the wet steam generator 5 (if necessary after conversion into superheated steam) is introduced not only into the first subspace 8a but also into the second subspace 8b. For this purpose, the steam supply channel 7 has a Y-shaped branch in the form of a Y-shaped valve 15, which is Figure 2The Y-shaped valve 15 has a (steam) inlet branch 15c connected to the steam side of the wet steam generator 5 and two (steam) outlet branches 15a and 15b of symmetrical design branching therefrom. The outlet branches 15a and 15b branch or lead to the first subspace 8a or the second subspace 8b.

[0062] The Y-valve 15 has a regulating device in the form of a pivotable valve flap 16 which can be electrically controlled by the control device 6. By adjusting the pivot angle of the valve flap 16, the steam flow rate Vin of the steam D flowing in through the inlet branch 15c can be variably adjusted to a steam flow rate Vout1 through the outlet branch 15a and a steam flow rate Vout2 through the outlet branch 15b, wherein Vin=Vout1+Vout2 applies. In particular, Vout1 can be set within the range of [0%, ..., 100%]·Vin. By this, the volume flow of the steam D flowing into the subspace 8a or 8b can also be proportionally adjusted, and Vin can be specifically changed by the electrical power input into the heating element of the wet steam generator 5.

[0063] The outlet branches 15a and 15b branch off or open into steam inlet openings 17a and 17b introduced into the front side 9v of the cooking vessel 9, which open into the subspaces 8a and 8b. If the cooking vessel 9 cannot be removed, the steam inlet openings 17a and 17b can directly correspond to the confluence of the outlet branches 15a and 15b. If the cooking vessel 9 can be removed, the steam inlet openings 17a and 17b can be simple perforations in one variant, which are connected to the section of the outlet branches 15a and 15b that is fixedly arranged in the drawer 1, and in another variant can be the confluence of a pipe-shaped channel section of the cooking vessel 9, which can be inserted, in particular in a gas-tight manner, into the section of the outlet branches 15a and 15b that is arranged in the drawer 1.

[0064] The steam inlet openings 17a and 17b are spaced so far apart from each other laterally in the front view that the rib 11 is arranged between them. This ensures that each of the subspaces 8a and 8b can be supplied with steam via the steam inlet opening 17a or 17b, that is, regardless of the position P1 to P5 of the partition 12.

[0065] Similar to the steam input openings 17a and 17b and advantageously at the same location in the front view, the cooking container 9 has two steam outlet openings 18a and 18b on its rear side 9b, through which steam or a steam / air / fume mixture can escape from the respective subspace 8a or 8b and flow into the steam outlet channel 10. The steam outlet openings 18a and 18b are also spaced so far apart from each other laterally in the front view that the rib 11 arranged on the rear side 9b is arranged between them. The steam outlet channel 10 has a merging portion 19 at which the branches connected to the two steam outlet openings 18a and 18b merge. In particular, the steam outlet channel 10 can have a merging portion 19 with respect to the steam outlet openings 18a and 18b. Figure 2 The flow cross section of the opposite branching or merging section 19 , which has two inlet branches and one outlet branch, can be adjusted, for example, by means of the valve flap 16 .

[0066] Of course, the invention is not limited to the embodiments shown.

[0067] Generally speaking, unless explicitly excluded by expressions such as “exactly one” etc., “a”, “an” etc. can be understood as singular or plural, especially in the sense of “at least one” or “one or more” etc.

[0068] Unless expressly excluded, numerical specifications may also include the exact number specified as well as the usual tolerance ranges.
