Description

[0001] The invention relates to a kitchen stove with a body that can be rotated about a vertical axis and supports the cooking surface.

[0002] Kitchen stoves are usually located stationary in the building.

[0003] In order to further enhance the spatial effect for the residents, it is provided according to the invention that the kitchen stove itself has a body which can be rotated about a vertical axis and which supports the cooking surface, with reversing and / or endlessly rotating rotary connections for the electrical energy supply and / or for the supply of fluid and / or gaseous media, in particular water, and / or for the disposal of waste water and / or for the extraction of cooking or frying steam.

[0004] This allows the stove's working area to be positioned anywhere within the room, allowing the cook's view to be directed, for example, through windows or doorways to the exterior of the building, but also to people in the room or even a screen. These effects can be further enhanced if the rotating stove is placed within a rotating structure, giving the cook an additional sense of immersion by retracing the daily routine.

[0005] The extended functionality of the kitchen stove is achieved by endless or reverse rotating rotary joints for the electrical power supply and / or for the supply of fluid and / or gaseous media, such as water or waste water and the like.

[0006] The ability to rotate the kitchen stove also makes it possible to observe certain situations outside the house, such as watching or supervising children in the pool or garden.

[0007] According to a first particular embodiment of the invention, the reversible rotary joints are designed as hoses and / or flexible electrical cables. For example, the kitchen stove can be rotated to a predetermined stop and then reversed to prevent hoses or electrical cables from kinking or being pulled off.

[0008] In the event that the kitchen stove or its hob is designed to rotate endlessly, the invention provides that the endless rotary joints for the material supply and disposal are designed as mechanical rotary unions with sealed and rotationally symmetrical connecting parts that rotate relative to one another.

[0009] From a design perspective, it is particularly advantageous if the mechanical rotary union for the fluid or gaseous media is designed as a multi-channel rotary union, with a cylindrical tube section that is stationary relative to the non-rotating, building-side section and a housing section that rotates with the kitchen stove or body and circumferentially surrounds the cylindrical tube section. The cylindrical tube section and housing section can have corresponding recesses, which each complement each other to form annular channels and which slide and seal against each other, with the recesses or channels having connections and / or outlets for the supply lines of the fluid and / or gaseous media on the side of the rotating kitchen stove and its non-rotating part or base. This type of rotary union enables continuous rotation of the kitchen stove relative to its surroundings.The kitchen stove can be rotated in both directions without any restrictions. This creates a maximum spatial effect, as the person inside the house is constantly being shown new, moving images of the outside area, like a film sequence. The stove's rotatability also offers a high degree of flexibility in use, for example, allowing you to watch or supervise certain situations outside the house, such as children playing in the garden or at the pool.

[0010] The cylindrical tube section is intended to be located on a service pipe that is fixed relative to the building, or to be part of the service pipe that carries the supply and disposal lines of the utilities. This conceals the supply and disposal lines from the outside, which should also meet aesthetic requirements.

[0011] According to a further concept of the invention, the annular channels, called ring channels for short, are arranged one above the other at an axial distance, so that no interface problems arise between the individual components, for example, mixing of process water and wastewater is avoided. The annular channels have corner-free, preferably circular cross-sections, so that deposits in the channels and thus disruption of the flow are virtually eliminated.

[0012] The rotating unions can be pipe connection parts that rotate coaxially within themselves and / or rotate on the end face of each other.

[0013] According to one concept of the invention, the rotating outlet for disposal can be arranged eccentrically to the rotational axis of the cooker or its body and merges into a funnel-shaped connecting part, which is arranged within the body of the cooker, the neck of which rotates on or around the tubular, fixed connecting part. This significantly increases the degree of freedom for disposal. In some cases, a shredding device for residues contained in the wastewater can even be dispensed with. Furthermore, this creates space in the center of the rotating cooker, allowing for convenient installation and maintenance work on the individual functional parts of the rotating cooker.

[0014] It is also conceivable that the rotating waste disposal outlet is arranged eccentrically to the axis of rotation of the body, the tubular connecting part of which flows into the funnel-shaped fixed connecting part at the base of the kitchen stove.

[0015] Of course, it is possible to install a shredding and / or cutting device in the disposal line that rotates with the body of the kitchen stove, especially the one for waste water, to reduce the particle size in order to prevent blockages in the drain lines.

[0016] To transmit electrical current or similar electrical signals, the supply devices for the gaseous and / or fluid media are arranged above the rotary joint, for example, an electrical rotary union with slip rings and associated sliding contacts. This prevents the risk of electrical short circuits. An electrical rotary joint is described, for example, in WO 2012 / 136646 A1.

[0017] By integrating devices for the supply of fluid and / or gaseous media and / or for the disposal of waste water, e.g. from a sink, or for the extraction of cooking or frying steam, practically an entire kitchen section can be designed to be rotatable.

[0018] According to the invention, the rotatability of the body can be easily achieved by providing a base on the floor of the building, on which a ring is mounted that rotates with the body. This design also allows for larger and heavier stove units to be designed to be rotatable.

[0019] According to the invention, it is also possible for at least one cabinet part to be slidably mounted on the body, whereby the functionality of the kitchen stove according to the invention is expanded with storage space.

[0020] The ability to move can be achieved by having at least one cabinet part suspended from the body by means of a guide rail system.

[0021] The storage area of ​​the cabinet section can essentially be flush with the work surface of the body or the cooktop. Food can be prepared on the storage area and then placed in pots or pans already on the cooktop, for example.

[0022] Additionally, the cabinet section can feature storage compartments on the side facing the body, which are released when the cabinet section is moved into an open position. This further expands the functionality of the kitchen stove, as the cooking and baking utensils stored in the storage compartments can be removed without leaving the stove.

[0023] An extension of this inventive concept involves two laterally movable cabinet sections arranged on opposite sides of the body, whose storage areas complement the work surface of the body to form a circle. The storage areas of the cabinet sections are circular segments, and the adjacent sides of the work surface of the body are trapezoidally aligned. This not only creates a visually appealing design but also a large work surface for the stove, accessible from all sides.

[0024] Furthermore, according to the invention, the body has drawers on its end faces not covered by the cabinet part(s), the drawer boxes of which are fully accessible from above.

[0025] Finally, the invention provides for the outer walls or panels of the cabinet sections and the fronts of the drawers arranged at the front of the body to form a cylinder. This effectively eliminates the risk of injury, as the stove has no protruding parts on the outside. The cylinder also lends the kitchen stove a special aesthetic appeal.

[0026] Further objects, advantages, and possible applications of the present invention will become apparent from the following description of an exemplary embodiment with reference to the drawings. All described and / or illustrated features, individually or in any meaningful combination, constitute the subject matter of the present invention, regardless of the claims or their dependence.

[0028] In the following figures of the drawing, identical or equivalent components are provided with reference numerals based on an embodiment in order to improve readability.

[0029] Fig. Figure 1 shows a possible embodiment of a rotating kitchen stove, which, as can be seen from Fig. 2, is mounted on a base 22 arranged on the floor of the building via a turntable 23 so as to be rotatable about a vertical axis 1.

[0030] In the example chosen here, the kitchen stove is not designed to rotate continuously, but rather with direct supply and disposal lines to the individual functional parts of the stove, which must be rotated backwards after a rotation of approximately 350°. The supply and disposal lines are Fig. 2 hoses 6, 7 are provided for the extractor rotary joint and electrical supply lines 8 for the hob 2.

[0031] The hob 2 with hob extractor 20 is carried by the rotatable body 3, on which two cabinet parts 9, 10 are slidably held.

[0032] The two cabinet sections 9, 10 are arranged on opposite longitudinal sides of the body 3, with their storage surfaces 11, 12 complementing the work surface 13 of the body 3 to form a circle. The work surfaces 11, 12 of the cabinet sections 9, 10 are circular segment-shaped, and the adjacent sides of the work surface 13 of the body 3 are trapezoidally aligned.

[0033] The cabinet parts 9, 10 are movable suspended from the body 3 by means of a guide rail system 16. The guide rail system 16 is made in particular of Fig. 4 or Fig. 5 can be seen.

[0034] The two cabinet parts 9, 10 have storage compartments 14, 15 on their sides facing the body 3, which are released when the cabinet parts 9, 10 are moved into an open position, as can be seen, for example, from Fig. 3, Fig. 4 and Fig. 5 is evident.

[0035] In the embodiment chosen here, pull-out drawers 17 are provided on the opposite end faces of the body 3, as can be seen from Fig. 5 and Fig. 6. The panels or fronts 19 of the pull-out drawers 17 are adapted to the outer walls 18 of the cabinet parts 9, 10.

[0036] Together with the opposite end faces or fronts 19 of the body 3, the work surface 13 with hob 2 and the flush-mounted storage areas 11, 12 of the cabinet parts 9, 10, an aesthetically pleasing cylinder is formed, which, for example, fits in a special way into a rotating house.

[0037] The kitchen stove according to the invention forms a special design element of modern kitchen architecture.

[0038] In the Fig. Figures 8 to 10 show a possible embodiment of an endlessly rotating kitchen stove.

[0039] In the embodiment chosen here, the material supply and disposal devices 24, 25 are formed by a rotary union 26, by means of which the material supply, for example with water, and the disposal of waste water and waste takes place, and an electrical rotary union 37 for supplying the rotatable hearth with electrical energy.

[0040] The rotary union for the fluid and / or gaseous media is formed by a cylindrical tube section 27 fixed to the floor, which surrounds a supply pipe 36, in which the supply lines for the rotary transformers 26, 37 and, if necessary, also the waste water lines are routed. The cylindrical tube section 27 can also be part of the supply pipe 36 and, if necessary, also be connected to the base 22 ( Fig. 2) of the kitchen stove.

[0041] This cylindrical tube section 27 is circumferentially surrounded by a preferably also cylindrical housing part 28, which rotates with the body 3 of the cooker. A rotation transmission rod (not shown) connected to the body 3 of the cooker is provided for the rotary connection and engages the outer housing part 28.

[0042] The cylindrical tube section 27 and the housing part 28 have corresponding recesses 29a, 29b, which complement each other to form annular channels and lie on top of each other in a sealed manner. Connections 30 to 35 for the supply and disposal lines from the rotating hearth or body 3 to the stationary lines are connected to these channels.

[0043] The individual ring channels are arranged one above the other at an axial distance, with their connections 30 to 35 being offset from one another in the circumferential direction to enable easier assembly and disassembly.

[0044] To prevent deposits from forming in the ring channels, they are designed to have a circular flow cross-section.

[0045] A shredding and / or cutting device (not shown) can be installed in the body-side disposal line, i.e. the one for the sink, in order to reduce the particle size in the wastewater and thus prevent blockages.

[0046] The electrical rotary feedthrough 37 has slip rings and associated sliding contacts not shown.

[0047] The electrical rotary feedthrough 37 is accommodated in a housing 38 which is electrically insulated to the outside and rotates with the body 3 of the cooker and is provided with feedthroughs for the electrical signal lines to the body 3 of the cooker.
