Description

The invention relates to a door for closing a cooking chamber of a cooking appliance. The door comprises a rear wall and a separate condensate collecting device, which is designed for collecting condensate draining from a rear side of the rear wall. In addition, the invention also includes a cooking appliance with such a door, which closes a cooking chamber of the cooking appliance.

It is known that in cooking appliances, in particular steam cooking appliances, condensate can form on a rear side of a rear wall of a door facing the cooking chamber. This then runs down from this back. In order to avoid unwanted dripping or running down from the rear side on the one hand into the cooking chamber and on the other hand with the door open on the floor or other objects or persons underneath, a condensate collecting device is provided.

It is from the DE 38 20 572 A1 It is known that in a lower region of the door, a channel fixedly attached thereto is arranged, in which the condensate draining from the rear side is initially collected. The gutter is mounted obliquely on the door in a horizontal, so that the condensate collected therein runs in a direction in the gutter. In the local version of a separate housing to the door of the Dampfgargeräts a turn there then fixed drip pan is attached. In this runs from the door-side channel running condensate. The inclination of the channel is provided so that when the door is open and thus a relative movement between the gutter on the door and the drip pan on the housing still the deeper end of the gutter above the sump is, so even in the open state of the door on the Gutter-led condensate should nevertheless enter the drip tray.

From the EP 0 170 910 A1 as well as the DE 10 2004 020 181 A1 Corresponding embodiments are known. There, in each case also a door arranged on the gutter and an external and the housing side arranged container or a tub is provided.

From the EP 1 918 644 A1 a flap door for a cooking appliance is known, on which a condensate tray is arranged.

It is an object of the present invention to provide a door for closing a cooking chamber of a cooking appliance, in which the collection and removal of condensate is improved in a condensate collection device. Accordingly, a cooking appliance to be created with such a door.

This object is achieved by a door and a cooking appliance according to the independent claims.

The invention relates to a door for a cooking appliance with a door leaf and with a condensate collecting device for collecting drainage condensate. The condensate collecting device is arranged on the door.

An essential idea of the invention can be seen in the fact that an elastic seal for application to a component of the cooking appliance, in the mounted and closed state of the door on the cooking appliance, is arranged on the condensate collecting device. The condensate collection device thus also serves as a holding device for such a separate elastic seal. As a result, the seal can be positioned in a highly exposed position and a corresponding highlighting sealing functionality can be achieved when the door is arranged on the cooking appliance. Furthermore, the accessibility to the seal, in particular for cleaning purposes or the like, is particularly advantageous. Also, by such an embodiment, the attachment of the seal assembly technology improved and easier possible.

It is preferably provided that the seal has a groove, in which engages the condensate collecting device. A particularly stable and secure attachment and attachment of the seal on the condensate collection device is thereby made possible.

It is preferably provided that the seal is designed as a sealing lip. It represents in particular a strip-shaped web. By such a configuration, the seal is very narrow, whereby it is arranged to save space and yet has a high elasticity. In addition, a tab-like design of the seal is realized by such a configuration, whereby a possible large-scale application of the seal to the component of the cooking device in the mounted state and closed state of the door is possible.

It is preferably provided that the condensate collecting device has a cantilevered web, at the edge of the seal is arranged. As a result, a retaining web is virtually created, which is also particularly advantageous in terms of its mechanical stability, space-saving design and can be oriented very accurately with respect to a preferred direction.

Preferably, the seal is arranged on this cantilevered web that it represents an extension of the web, when the door is not applied to the component of the cooking appliance. The seal is also arranged as cantilevered.

This freely cantilevered web of the condensate collecting device is preferably arranged projecting beyond a rear side of the door leaf in the depth direction of the door and thus also of the cooking appliance, and thus is arranged so as to protrude quasi to the rear. The exposed positioning of the seal with the then desired reliable contact with the component of the cooking appliance is thereby made particularly advantageous. In addition, this configuration also achieves a certain degree of elasticity and spring action of this cantilevered web, if necessary, so that individual positional changes, in particular to a tolerance compensation in a resulting full-surface and particularly notable sealing effect of the seal, are also made possible here when the door is arranged in the closed state on the cooking appliance.

It is preferably provided that this cantilevered web is arranged obliquely to a plane in which the door leaf extends. In a vertical sectional view, this inclination is oriented towards an upper end of the door leaf. As a result of this embodiment, the web is also functionally designed as a guide element, so that a condensate downwards draining off condensate via the seal and the web is also purposefully continued or forwarded.

It is preferably provided that the condensate collecting device is arranged below a disc package of the door leaf as viewed in the vertical direction. In a door of a household appliance is provided that it has at least two plate-like glass sheets, which are spaced apart parallel to each other. There may also be three or more such disks, wherein the disk package is formed by the at least two disks. Due to the specific positioning of the condensate collecting device relative to the disk pack, a particularly compact construction of the door is also realized here and also a protected arrangement of the condensate collecting device is made possible. In addition, it is also then in the opened state of the door easily accessible and easy to remove and reusable.

It is preferably provided that the condensate collecting device is formed with a collecting trough, which is arranged in the direction of depth within an outer dimension of a disk package of the door leaf. The above advantages are further improved. In addition, a certain impact protection for the sump is then realized by this design, so that it is not damaged and thus an undesirable leakage of already collected condensate is avoided.

It is preferably provided that the condensate collecting device has a collecting trough and a cover which is separate therefrom, wherein the cover has at least one inlet opening for the condensate. With this configuration, the condensate collection device is easy to disassemble and reassembled. It forms in the assembled state of their components mentioned a quasi closed container to the inlet openings, so that an undesirable escape of the already collected condensate liquid is prevented. On the other hand, the accessibility into the interior with removed collection trough is easily possible, so that the cleaning of at least the sump is easy and reliable possible. This hygienic requirements can be taken into account accordingly.

It is preferably provided that the cover of this condensate collecting device has a retaining wall which engages in a receptacle in the door leaf. This is another very advantageous embodiment, since thus a special individual holding concept is realized. By this cover is thus virtually created a separate additional part, with which then a fixation to the further door structure of the door is possible. The attachment to the door leaf is thus simple and yet positionally possible. By this embodiment, an easily accessible and easily realizable attachment of the sump at this preferably attached to the door panel further component, namely the cover is reached.

It is preferably provided that the cantilevered web, on which the seal is then arranged, is integrally formed on the cover and forms with the retaining wall an inlet channel for the condensate running down. The cover is preferably formed in one piece. Through this designed cover quasi an open-top hopper is formed, so that the running condensate can be collected particularly advantageous and circumferentially and is directed into the sump. Preferably, the inlet opening is formed at the bottom of this inlet channel. A reliable shrinkage of the condensate from the cover into the sump is thereby made possible.

In an advantageous manner, the cover, in particular the inlet channel, is Y-shaped in a vertical sectional view. A particularly advantageous embodiment is characterized on the one hand in the With regard to the attachment of the cover on the door leaf and on the other hand with respect to a comprehensive recording and forwarding of the condensate allows. Last but not least, mechanical attachments of the collecting sump to the cover are highlighted.

It is preferably provided that the cover is arranged non-destructively detachable on the sump. In particular, a locking is provided here. A simple, yet position-safe and permanently stable mechanical connection is achieved. Additional fasteners such as screws or the like are then not required.

Preferably, the condensate collecting device is arranged non-destructively releasably on the door leaf.

It is also envisaged that the condensate collecting device can be formed individually, especially if it is constructed in several parts. For this purpose, it can be provided that the cover is used as an equivalent component for several variants of the door and is fastened to the door leaf. It can then be provided various collection troughs, which then allow the variant formation. All collecting troughs are particularly designed so that they can be attached to the same cover.

Furthermore, the invention also relates to a cooking appliance with a housing, on which a door according to the invention or an advantageous embodiment thereof is arranged.

The cooking appliance is in particular a steam cooking appliance, in which it is then particularly advantageous to be able to safely absorb the condensate draining from the door and / or a housing flange. In the cooking appliance, the door is designed in particular as a hinged door, which means that it can be pivoted or hinged about an oriented in the width direction of the cooking device lower pivot axis.

When the door is opened, the condensate flows directly into the condensate collector. A gap between the door and a front side housing flange, in particular a front flange of a muffle, which limits a cooking chamber of the cooking appliance is sealed in this then still small opening position by the seal, which due to their arrangement and design then at this small opening angle still on the Flange of the housing is applied. Upon further opening of the door, the mechanical contact between the seal and this flange then dissolves and the condensate which continues to run off the door leaf passes into the condensate collecting device. The condensate collecting device therefore moves with the door, since it is stationary on the door.

The terms "top", "bottom", "front", "rear", "horizontal", "vertical", "depth direction", "width direction", "height direction", etc. are the intended use and intended arrangement of the container and at a given then before the container standing and looking in the direction of the container given positions and orientations.
