Description

The invention relates to a household appliance for preparing food, with a housing in which a cooking chamber is formed. The household appliance also includes a hob, which is electrically connected to a wired electronics in the housing. In a cover of the housing, an opening for carrying at least one electrical line between the hob and the electronics is formed.

From the DE 103 45 198 A1 a module for controlling a hob is known. This electronic module is connected by means of electrical cables to the hob. In an opening of a cover of a housing of a separate oven to this electronic module is used to be electrically connected to the electrical components in the oven.

In household appliances for preparing food, which have a hob and an oven, electrical interfaces between the hob and the oven are formed. It is advantageous to make the oven arranged in the electrical components for connection to the hob from above and thus accessible via a cover of the housing of the oven. This simplifies handling for assembly and maintenance. Live components must be protected against direct contact.

It is an object of the present invention to provide a household appliance for preparing food, in which the passage of electrical lines through a cover of a housing of a household appliance for preparing food, which extend between a hob and the housing, is improved.

This object is achieved by a household appliance having the features of claim 1.

An inventive household appliance for preparing food comprises a housing in which a cooking chamber is formed. In addition, the household appliance comprises a housing separate hob, which is electrically connected to a wired electronics in the housing. The hob is located outside of the housing. In a cover of the housing, an opening for carrying at least one electrical line between the hob and the electronics is formed. An essential idea of the invention is to be seen in the fact that on the cover there is arranged a pivotable lid for closing the opening. Even in the connected state of the electrical line with the electronics in the housing, therefore, this opening is additionally covered by the pivotable lid. This can prevent the ingress of dust or dirt or liquids. Moreover, with such a hinged lid, the possibility of opening and closing at any given time is required. This allows for mounting purposes during maintenance at any time access through the cover and the lid to the electronics. Due to the pivotable design of the lid this is also very easy and fast to spend in its closed or open position. Elaborate installation effort, which would occur for example by circumferential screw or the like, can be avoided. In addition, by such a pivotable arrangement of the lid this also at any time even with many times repeated opening and closing, especially in the closed state in its exact position. The above-mentioned advantages with regard to a reliable prevention of penetration of dirt or liquid into the housing via the opening of the cover is thereby further improved.

The housing is in particular part of a baking oven, and thus forms the housing of the oven. The oven is part of the household appliance. The housing and thus the oven is designed separately from the hob.

It is preferably provided that the cover is arranged integrally on a frame module having a cover module. This is a particularly advantageous embodiment, since thus the lid is not directly pivotally attached to the cover, but is arranged directly on a separate frame to cover. Such a cover module with the frame and the lid allows on the one hand a mechanically stable and very precise position attachment in the opening of the cover. The in itself very stable and rigid frame can then be fixed in place in the opening. The pivotally mounted on the frame lid is therefore permanently movable safely. In addition, a particularly dirt-proof and liquid-tight closure of the opening is achieved here. In particular, this frame of the cover module is inserted in the opening of the cover.

The cover module is a separate unit to the cover.

Advantageously, the lid of this cover module is arranged with a film hinge on the frame. As a result, a captive connection is created, which is also very smooth.

In addition, no such assembly effort between the lid and the frame is required by such a configuration, since this production structure is already created by manufacturing reasons.

It is preferably provided that the cover module is integrally formed from plastic. This is particularly advantageous in that the cover module can thus be designed with a very low weight and is not electrically conductive.

With particular advantage, in the case of an embodiment made of plastic, it is provided that the cover module is formed, at least in regions, from a material which has a high capillary action. As a result, in particular a liquid-repellent design is created, which allows it to a particular extent that liquids can not or only in a targeted way through the cover module and thus can not reach the electronics in the housing. Such a capillary material embodiment of the cover module allows liquid to flow selectively in certain directions or to certain quasi collection points, so that by this way then desired and defined in a certain direction this liquid are derived.

It is preferably provided that the frame has connecting pins for connection to the cover. As a result, the frame can be brought into the desired position very easily and yet with high precision. In a particularly advantageous manner it is provided that the connecting pins are made of plastic, which are then fastened in particular by hot stamping or hot riveting in recordings in the cover. The position-fixed arrangement of the cover module, in particular the frame in direct connection with the cover is achieved. In addition, a captive attachment of the frame to the cover can be made possible by such a configuration, which is thus formed non-destructive nondestructive.

It is preferably provided that the cover module has at least one integrated cable guide. As a result, the electrical lines between the hob and the electronics in the housing can be kept very targeted to the cover module and continued. On the one hand, this favors the purposeful laying of these electrical lines, and on the other hand just at the transition or during the passage through the cover module, a laying that minimizes gaps, so that here again through these interfaces, where the cables or electrical lines are passed through the cover module, a penetration of dirt and liquids is reduced or prevented.

Preferably, it is provided that the frame has on an inner boundary wall at least one, in particular with both ends of the boundary wall opening, headband as a cable guide. As a result of the local mounting, the electrical lines are routed in a quasi-vertical manner downwards into the housing in a deliberate manner, so that they are, as it were, routed along the shortest path to the electronics in the housing. In addition, such a headband, which then also opens on both sides of the boundary wall, to the effect advantageous because it surrounds in the circumferential direction to the electrical line and thus also the cable this over a long length and thus rests on the outside thereof. A preferably positive fit in this respect the attachment of the retaining clip is made possible, so that the positionally secure holder is achieved particularly advantageous with the headband.

It is preferably provided that the cover has at least one integrated dome-like elevation, which is formed towards a lid edge with a cable opening. The dome-like elevation therefore provides high stability on the one hand and maximum top and side coverage on the other hand. The only only one existing cable opening, which is then also specifically directed, namely the lid edge is formed open, allows virtually a lateral or horizontal installation and introduction of coming from the hob electrical lines in the cover module. Thus, viewed virtually in the vertical direction, no opening or a gap is formed, so that the penetration of dirt or liquids is significantly more difficult.

Advantageously, it is provided that the survey is designed facing away from the frame in the closed state of the lid.

Advantageously, a sealing element is arranged on the cover and / or the frame, so that in the closed state of the lid, a sealing connection between the cover and the frame is formed. The penetration of dirt or liquids is thereby particularly effectively prevented.

In addition, can be compensated by such an additional seal or a sealing element and a shape tolerance of the lid and / or a frame, so that almost completely circumferentially around the contact surfaces of the lid and the frame an uninterrupted abutment is created.

In particular, it is provided that on the frame, a sealing element is arranged, through which a sealing contact of the frame is achieved on the cover in the region of the opening. As a result, the penetration of dirt or liquid in the mechanical interface between the frame and the cover is improved prevented and shape tolerances can be compensated.

It can be provided that the headband and the spaced elevation are arranged with the cable opening in the closed state of the lid to each other so that a performed by the headband and the cable opening electrical line on the way between the headband and the cable opening non-rectilinearly arranged is. In particular, it is provided that this electrical line between the headband and the cable opening of the survey at an angle between 80 ° and 95 ° and in particular 90 °, is arranged. The advantages mentioned above are thereby particularly favored.

Preferably, it is provided that the cable guide has a, in particular formed by a formed on the frame headband, strain relief for a guided electrical line. As a result, the position security is increased again and the generated electrical connection between the electrical line and the electronics in the housing and the connection between the electrical line and the hob on the other hand experiences no unwanted application of force.

It is preferably provided that the lid is locked in the closed state on the frame. As a result, the closed position is kept permanently secure.

It is preferably provided that the cover is plate-like and the lid is arranged as an insert part in the cover.

The cover is preferably made of metal. It preferably extends over the entire upper dimensions of the housing and thus also constitutes an upper wall of the housing. The cover and thus in particular also the cover module are likewise preferably plate-like and do not constitute a housing for electronic components as such. Electronic components are thus not enclosed by the lid or the cover module surrounding.

The receptacles in the cover for introducing the connecting elements, in particular the connecting pins on the frame of the cover module are produced in particular by punching. In particular, the material of the cover and / or the frame of the cover module is designed so that a capillary effect occurs, which optionally still slightly penetrating water derived in such a way that it does not come into contact with live parts and can run safely. This is also achieved by the cable guide, in particular by the locally specifically arranged and geometrically specifically shaped headband. The electrical lines or the cables are then specifically guided and routed so that, if necessary, even slightly penetrating liquid medium from these electrical lines or cables does not reach the electrical contacts of the electronics in the housing.

Due to the embodiment of the invention, it is also possible that the electrical interface of the hob can be maintained virtually unchanged and the compatibility with existing hobs can be maintained. Nevertheless, in particular the protection against ingress of dirt, in particular liquids, is given or, in particular, basically only available.

The indications "width direction", "height direction", "depth direction", "top", "bottom", "front", "rear", "outside", "inside" etc. for the household appliance refer to the state a set up for a conventional use and thus intended use household appliance, the door is arranged in front for a viewer and the back of the back.
