DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE PRESENT INVENTION

(9) In the drawings, the same or functionally identical elements are provided with the same reference characters.

(10) FIG. 1 shows a simplified representation of a cooking appliance 1, which may be a steam cooking appliance, for instance. The cooking appliance 1 comprises a housing 2 in which a cooking chamber 3 is embodied. The cooking chamber 3 is accessible at the front through a loading opening, which can be sealed by a door 4. The door 4 can be rotated about a vertical axis of rotation A which is thus oriented in the height direction (y-direction). The door 4 is therefore a rotary door, which is pivotably hinged to the left on the housing 2 in the exemplary embodiment shown.

(11) In the exemplary embodiment, the door 4 has at least two separate panel parts, which, according to the perspective representation in FIG. 2, represent an outer panel or a front panel 5 and an inner panel or rear wall 6 separated therefrom. The front panel 5 and the rear wall 6 embodied as an inner panel are preferably embodied parallel to one another or slightly inclined to one another and are preferably glass panels.

(12) A perspective view onto a rear side 7 of the rear wall 6 is shown in FIG. 2, wherein, in the closed state of the door 4, this rear side 7 is facing the cooking chamber 3, or generally facing away from the front panel 5.

(13) In particular during operation of the cooking appliance 1 and thus when the door 4 is closed, condensate can form on the rear side 7, which then runs downward on the rear side 7 under gravitational force. In order to catch and collect this condensate, the door 4 comprises a condensate collection device 8. The condensate collection device 8 in turn has a collection and guide rail 9 and a collection container 10. The collection and guide rail 9 and also the collection container 10 are arranged in a fixed manner on the door 4, in particular on the rear wall 6. The collection and guide rail 9 and also the collection container 10 are preferably arranged in a fixed position relative to one another, irrespective of how the door 4 is moved or which position it has currently assumed. The collection is preferably carried out once the door 4 is moved out of its completely closed position and is thus opened. In particular, provision is made in one embodiment for the condensate to run back into the cooking chamber when the door 4 is completely closed, particularly on account of the embodiment of a seal between the door and a cooking chamber flange.

(14) As is apparent, the collection and guide rail 9 preferably extends across the entire width of the rear wall 6 and thus in the width direction and thus in the z-direction across the entire width dimension of the rear wall 6, in particular in a lower region 11.

(15) FIG. 3 shows a perspective representation of the condensate collection device 8 in one exemplary embodiment. Provision is made in this embodiment for the collection and guide rail 9 to be embodied in one piece with the carrier 12. The carrier 12 and the collection and guide rail 9 are embodied in one piece here and are in particular molded correspondingly by means of bending from a blank made of spring steel or stainless steel. A bent component is thus embodied here. With this embodiment, the collection container 10 is designed as a separate component and produced from plastic, for instance.

(16) As is apparent, the carrier 12 comprises a first panel part 13 and a second panel part 14 resting thereon and extending in parallel thereto. The panel parts 13 and 14 are connected by means of an upper bend 15. The collection and guide rail 9 leads onto a free edge 16 of the first panel part 13, which opposes the upper bend 15. The collection and guide rail 9 comprises a trap sheet 17 and a guide strip 18. The trap sheet 17 extends in a plane, which is arranged at an angle from the plate-shaped guide strip 18. The angle preferably amounts to between 100° and 130°. As apparent in the representation in FIG. 3, the trap sheet 17 is embodied at least in regions with a double layer across its planar dimensions, wherein here in particular the double layers are achieved by means of a fold. Cover flaps 19 and 20 connect to the trap sheet 17 in the longitudinal direction (x-direction in FIG. 2) on opposite ends, wherein these flaps 19 and 20 are molded on opposing edges of the guide strip 18 and are bent upward by means of bending.

(17) Furthermore, uparchings 21 are embodied on opposing edges in the longitudinal direction of the guide strip 18, which extends in the width direction and thus in the x-direction. As a result, an unwanted draining of the condensate which occurs laterally or in the direction of the longitudinal axis of the collection and guide rail 9 is avoided.

(18) Furthermore, it is apparent in FIG. 3 that a receiving region 22 for receiving the collection container 10 also leads onto the carrier 12, in particular onto the free end of the panel part 14 which opposes the upper bend 15. The receiving region 22 can be deformed elastically and to this end has in particular one, in the exemplary embodiment two, spring elements or spring lugs 23 and 24. The collection container 10 can be latched or snap-fitted into this receiving region 22, and by means of the elastic spring lugs 23 and 24 the clamping effect is then achieved. Provision can also be made for the lugs to be rigid and the collection container 10 to be elastically deformable.

(19) As is apparent, the collection container 10 is embodied in the manner of a channel or trough. It is likewise produced preferably in one piece.

(20) As is apparent, the guide strip 18 leads obliquely onto the first panel part 13, wherein an angle between the plane, in which the first panel part 13 extends, and a plane in which the guide strip 18 extends, is smaller than 90°.

(21) FIG. 4 shows the assembled state between the single-piece component comprising the collection and guide rail 9 and the carrier 12 with the collection container 10.

(22) FIG. 5 shows an enlarged representation of a subarea of the arrangement of the elements according to FIG. 2 along the line of intersection V-V. As is apparent here, the collection and guide rail 9 is arranged in the lower region 11, but at a distance therefrom. In particular in the height direction and thus in the y-direction, the guide strip 18 is distanced downward from a lower edge 24 of the rear wall 6. In the depth direction and thus in the z-direction, the guide strip 18 is however dimensioned such that it extends on both sides of the rear wall 6 and therefore has larger dimensions than a thickness d of the rear wall 6. Furthermore, it is also apparent that the trap sheet 17 at an angle from the plane of the rear side 7 extends downward or is arranged at an angle thereto such that a funnel-type inlet is formed between the rear side 7 and the trap sheet 17. The groove shape of the inlet makes it possible for the condensate on the rear side 7 not to run unintentionally past the collection and guide strip 9. As is apparent, an angle between the trap sheet 17 and the rear side 7 in a y-z plane is preferably less than 60°, in particular between 20° and 45°.

(23) By means of the arrows, the route of the condensate P from the rear side 7 into the collection container 10 is indicated by way of example. It is apparent here that the condensate P runs downward via the rear side 7 and in the exemplary embodiment runs past a holder 25 on the outside, which surrounds the lower edge 24 with a preferably U-shaped rail, and thus passes through between this holder 25 and the collection and guide rail 9. On the top side of the guide strip 18, which is oblique compared with a horizontal plane, the condensate P then runs as far as a drip edge 26 of the guide strip 18 and then drips or runs into the collection tray or the collection container 10 arranged therebelow. As is apparent, the carrier 12 is fastened to the holder 25. In particular, provision is made here for the first panel part 13 to be fastened thereon. The holder 25 is provided and embodied in particular to hold at least the rear wall 6.

(24) A connection 27 between the collection and guide rail 9 and the carrier 12 is not embodied across this entire length in the direction of the longitudinal axis, which extends in the x-direction, but only in regions in this regard. A number of connecting points which are arranged separated and at a distance from one another are preferably embodied in this connection. Clearances are then produced between these connecting points, through which the condensate P can run and can extend into the collection container 10. Individual drip edges 26 are then formed on the guide strip 18 in these clearances. As is apparent in FIG. 5, one end which leads onto the trap sheet 17 in the height direction and thus in the y direction or one edge of the guide strip 18 which leads thereto is therefore arranged higher than an edge which has the at least one drip edge 26 and which faces away from this trap sheet 17.

(25) It is also apparent in FIG. 5 how the receiving region 22 is embodied in its region facing the carrier 12. A pocket 28 is formed here, in which a channel wall 29 of the collection container 10 engages or undercuts. This pocket 28 is embodied by a preferably S-shaped mold, so that on the one hand the positionally secure arrangement of the collection container 10 is achieved and a slipping in at least two spatial directions is thus prevented. The upper end of the channel wall 29 is thus pressed into this pocket 28 by the upwardly acting spring force of the spring lugs 23 and 24.

(26) FIG. 6 shows a perspective representation of a subregion of a single-piece embodiment of a component with the collection and guide rail 9, the carrier 12 and the receiving region 22. It is apparent here that a number of connecting points 27a are embodied and clearances 27b are designed therebetween in each case, so that as a result the condensate P can run or drip from the guide strip 18 and can reach the collection container 10. In this embodiment, only the spring lug 24 is shown.

(27) FIG. 7 shows a perspective view of the cited single-piece component which differs from FIG. 6. The double layers of the trap sheet 17 are shown here, wherein here corresponding lugs are molded on a fold web 30, which forms the second position, wherein these lugs 31 preferably rest in a form-fit manner on the first layer 32 of the trap sheet 17, and are thus molded accordingly, on the other hand they also rest on the guide strip 18. This achieves a particularly high form stability of the collection and guide strip 9.
