Description

The invention relates to a Dampfgargerät with a water tank and an evaporator unit, with which water of the water tank is vaporized and the steam in a cooking chamber of Dampfgargeräts can be introduced, wherein the water tank is arranged externally to the cooking chamber.

Steam cooking appliances are known in various configurations. In embodiments, it may be provided that a water tank, in which the water, which is then to be evaporated, firmly integrated into the device and is not removable. In other embodiments, it is provided that this water tank can be reversibly removed and replaced. Systems are also known in which the water tank can be pulled out from the front of the steam cooking appliance and pushed back in again. In the currently known embodiments with retractable and removable water tank, it may be relatively complicated due to the configurations for a user to carry out the removal process and in particular the insertion process. This can result in misalignments or jamming. As a result, a spill over of the water in the tank can take place, so that in this regard can leak and contamination of the environment may occur. In addition, in known systems after pulling out a dripping from the docking of the water tank on the ground or a front of the device occurring.

It is an object of the present invention to provide a steam cooking appliance, in which the water tank can be removed and used again in a simple and user-friendly manner.

This object is achieved by a steam cooking appliance, which has the features of claim 1.

A steam cooking appliance according to the invention comprises a water tank and an evaporator unit, with which water of the water tank can be vaporized and the steam can be introduced into a cooking chamber of the steam cooking appliance, the water tank being arranged externally to the cooking chamber.

The Dampfgargerät has a drawer, wherein the water tank is attachable in the drawer. When inserted, the water tank is arranged in the drawer. For such a configuration, on the one hand, the accessibility to the water tank is particularly favorable and it can also be ensured by the mobility of the entire drawer a tidy and mechanically stable attachment of the water tank. An appropriate extraction and retraction of the drawer thus virtually guarantees an additional recording of a component that can be moved itself, so that even when removing the water tank unwanted run out of water can be avoided.

It is preferably provided that the drawer is horizontally displaceable and the water tank in the extended state of the drawer is accessible from above. By this embodiment, the above advantages are further improved. In addition, can be designed without interruption by such a configuration, the front of the Dampfgargeräts with the front of the drawer and it is virtually the front of the drawer is no longer provided with an opening for the water tank. Not least, this concept also favors the handling of the water tank with regard to drip-free refilling and the like.

It is preferably provided that the water tank is arranged detachably in the drawer, in particular can be removed upwards. Especially with such a separability of the water tank from the drawer, the basic concept with an additional component, which is also still movable and arranged to receive the water tank, particularly advantageous. Removing up and down is also more user-friendly. In particular, it is possible by the improved insight into the entire application of the water tank in the drawer with targeted introduction. In particular, then the dripping and leakage of water from the device when removing or when inserting the water tank from or into the drawer is avoided.

It is preferably provided that the drawer has a, in particular accurately fitting, receiving area for the water tank. The position-fixed arrangement in the drawer can be ensured and unwanted slippage of the water tank can be avoided.

It is preferably provided that at least one wall of the receiving area has at its upper portion an outwardly inclined wall portion. By such a configuration, the insertion of the water tank can be improved from above, since quasi a certain funnel-like guidance is ensured in the receiving area precisely in precisely fitting arrangements in the final position of the water tank in the drawer through these inclined surfaces. An undesirable jamming or spreading and damaging the water tank or the drawer can be avoided.

It is preferably provided that at least two opposite walls have at their upper portions an inclined wall portion. The above advantages can be further improved.

It is preferably provided that the water tank has a, in particular movable, handle. The removal and insertion is thus even more user-friendly and more accurate.

Preferably, the handle can be brought by a flap unit automatically from a folded into an unfolded position. Therefore, the user does not have to spend the handle in the folded position in the unfolded position, which is particularly advantageous and user-friendly especially in hard-to-reach folded positions of the handle.

It is preferably provided that the handle is arranged in the closed position of the drawer in the retracted position and held by the abutment of the handle on an inner wall of the Dampfgargeräts in the folded position. In particular, when pulling out the drawer, the concern is released on the inner wall and the handle is automatically brought up by the flap unit in the unfolded position. Thus, in functionality of the flap unit as well as the targeted.

Design and arrangement of the water tank in the movement guide to pull out the drawer and then remove the water tank created a particularly advantageous automatizing principle. This too is favored to the effect that a clamping or spreading is avoided and the transfer of the folded position state in the unfolded position state is quasi-continuous and not snapping.

Preferably, the handle is in its extended position in a vertical position, so that the gripping and removal of the water tank from the drawer upwards for a user is very smooth.

Preferably, it is provided that the handle located in the unfolded position contacted when inserting the drawer in the steam cooking appliance on the inner wall and automatically upon further insertion can be brought into the folded position and rests against the inner wall. Preferably, therefore, the handle works from the preferably vertical unfolded position in the further horizontal insertion of the drawer into the steam cooker by the stop on the front edge and then on the inner wall automatically forward in the horizontal folded position. This is a particularly favored motion control for the automatic movement of the handle in the folded position.

It is preferably provided that the flap unit comprises a spring, in particular a spring. This is in particular fixed and arranged so that the handle would be almost automatically brought into the unfolded position. If the handle is in the folded-in position, the spring is quasi brought into a prestressed state which would like to push the handle outwards against this position and would like to transfer it into the unfolded position. Especially in the closed state of the drawer and the concern of the handle on the inner wall of this bias is thus counteracted.

Preferably, it is provided that a docking connection of the water tank for coupling with a line system for feeding the water into the cooking chamber for evaporation there or for feeding the garraumextern generated steam is coupled to the cooking chamber in the fully inserted state of the drawer with a docking area of the conduit system. It is thus achieved when inserting the water tank in the pulled-drawer yet no such coupling of the docking with the docking area. Since in this respect a practically vertical movement takes place and in terms of docking an axial connection is particularly advantageous, the above-mentioned advantageous embodiment can be very targeted then achieved when the drawer is pushed in horizontal rectilinear movement inward and thereby then the desired axial Docking of docking with the docking area can be done very precisely.

It is preferably provided that at least one operating element and / or a display unit of an operating device of the steam cooking appliance is integrated in the front wall of the drawer and is arranged and accessible on the front side. This is a particularly noteworthy embodiment, since characterized the drawer is quasi multi-functional and serves as a carrier for several different functional units of Dampfgargeräts. On the one hand, this makes it possible to achieve a particularly compact design for the components. In addition, the front wall of the drawer can be used to hold the operating device. Especially when a Dampfgargerät is provided, which in any case has a control panel with an operating device, in this embodiment, the front wall of the drawer serves as such control panel with the operating device.

Preferably, it is provided that the drawer over the entire width of the Steam cooker extends. As a result, especially for very large operating devices, this can advantageously be used to accommodate at least partial elements of the operating device, which can then also be positioned in a clearly arranged and user-friendly manner. In addition, a particularly large water tank can be accommodated by such a large-sized drawer.

Especially in embodiments in which an operating device is integrated into the drawer and virtually serves as a control panel, the space arranged behind it can be additionally used by the shipment and installation of the water tank over conventional designs of household appliances and Dampfgargeräten with only one control panel.

It is preferably provided that the drawer is arranged above a cooking chamber and above a door for closing the cooking chamber.

It is preferably provided that the drawer is arranged displaced in its fully inserted end position and its fully extended end position. Even with a slight bumping of a user and when removing or inserting the water tank, this drawer can not then undesirably slip or move, so that such a removal operation or use operation is not hindered. However, this embodiment is particularly advantageous if the operating device is arranged on the front wall of the drawer. If this drawer then in the extended state and fixed in position or displaced, the operating device, in particular an operating element at any time by pressing, or rotating or the like can be operated without the drawer moves inward and thereby the operation would be impaired.

It is preferably provided that the drawer is positioned displaced by a holding device. For example, a locking mechanism or a locking mechanism can be provided here. It can be provided that retraction can be effected in the retracted state of the drawer so that a holding device can be actuated by a push-pull mechanism (push-pull mechanism). However, it may also be provided that a simple release button is provided, with which the displacement-fixed position can be unlocked and then manually by a user, the drawer can be pushed back and forth.

Particularly advantageous is provided that the Dampfgargerät has a motor through which the movement of the drawer can be done automatically driven. Preferably, a movement damping device is then also provided that an undesirable hard hitting the end positions of the drawer can be avoided. As a result, especially in the presence of an operating device damaging this electronics can be avoided.

It is preferably provided that the evaporator unit of the cooking appliance is arranged in the drawer. Even with such a cooking chamber externally arranged evaporator unit thus minimizing the space is provided in the drawer as an additional recording medium. In particular, it can be provided that the evaporator unit is arranged in the water tank itself. The steam to be generated can then be supplied in a particularly advantageous manner via the line system in the cooking chamber.

It can be provided that the Dampfgargerät has a power supply unit which is arranged for electrical or thermal energy transfer to the evaporator unit, which is arranged in the drawer or the water tank, external to the drawer. In particular, it is provided that an energy transfer from this power supply unit to the evaporator unit can be carried out only in the inserted end position of the drawer. It may be provided here that an electrical power supply for the evaporator unit takes place in which this takes place by wire and contact electrical contacts on the evaporator unit in the end position of the drawer with electrical contacts of the power supply unit.

However, it can also be provided that in this regard a wireless energy transmission takes place. In particular, it is also possible that in the end position of the drawer in the inserted state electrical energy from a drawer external arranged induction coil to the evaporator unit is transferable. It can also be provided that in the end position in the inserted state of the drawer, an externally arranged to the drawer heater is activated and thermal energy, for example in the form of contact or radiant heat is transferred to the evaporator unit and then by heating the water in the water tank is evaporated.

With regard to the transfer of the drawer in the extended state in the fully retracted end position can be provided that this is done by a user guided and, for example, against a biasing element, such as a spring, so that with the pushing in a counterforce is generated by the spring , This too becomes an undesirable hard one Hitting the drawer in the inserted end position avoided. It can also be provided that the drawer is first unlocked in the displacement-fixed fully extended end position and then simply pushed into it by a user. However, it is also possible to start a motor by, for example, pressing a key, which then automatically moves the drawer into the end position via the motor drive.
