Description

The present invention relates to a cooking appliance comprising at least one housing device, at least one cooking chamber with at least one cooking chamber opening, at least one cooking chamber door closing the cooking chamber opening and at least one panel device. The diaphragm device surrounds the cooking space opening at least in sections and the housing device has at least one contact section for the diaphragm device. Steam can be supplied to cook food in the cooking space.

Cooking appliances such as steam ovens are available as free-standing appliances and as built-in appliances.

The publication EP 1 298 394 A1 shows a cooking device as a standing device. With a free-standing unit, the side parts of the housing and the front can always be visible. Framing the cooking chamber door and receiving the controls, the cooking appliance has a front panel on the front visible when the cooking chamber door is closed.

In built-in appliances, the housing is pushed almost completely into a cabinet by the cooking appliance in order to be integrated into a kitchen front in a visually appealing manner. The closed cooking chamber door of the cooking appliance then usually forms a flush finish with the rest of the kitchen front.

In order to enable an optically appealing closure of the cooking appliance even when the cooking chamber door is open, so that the view of the furniture body and the housing of the cooking appliance is covered, a front panel is usually provided, which represents a visually perfect closure of the cooking appliance when the cooking chamber door is open. A cooking device with such a front panel is, for example, from the publication DE 101 06 824 A1 known.

This front panel is often made of metal, in particular stainless steel, in order to provide a heat-resistant front which can come into contact with the steam from the cooking space. The document discloses such a metal front panel EP 2 314 932 A1 . A disadvantage of front panels made of metal or stainless steel, however, is that the production of the front panel is quite complex and costly, since stainless steel cannot be shaped and machined arbitrarily.

It is therefore the object of the present invention to provide a cooking appliance in which the front panel is easier to manufacture.

This object is achieved by a cooking device with the features of claim 3 and by a method for installing a cooking device with the features of claim 1. Preferred developments of the invention are the subject of the dependent claims. Further advantages and features of the invention result from the exemplary embodiments.

The method according to the invention is suitable for installing or assembling a cooking appliance, as will be described below. At least one pin device is provided on the rear of the diaphragm device and the contact section for the diaphragm device has at least one corresponding through opening. The pin device is passed through the through-opening and then reshaped in such a way that the diaphragm device is at least sectionally firmly connected to the contact section.

In particular, a plurality of pin devices can be provided on the rear side of the diaphragm device, in which case corresponding passage openings are provided on the contact section for the diaphragm device. Preferably, so many pin devices and through openings are provided that a force and / or positive connection between the diaphragm device and the contact section can be achieved. By means of a hot-stamped shaping, for example, the pin device can be pressed flat in such a way that a kind of mushroom head is created, as a result of which the diaphragm device is held securely at the through opening or at the contact section.

The method according to the invention offers many advantages. A considerable advantage is that the special design of the plastic cover device with pin devices on the rear side enables particularly simple installation of the cover device on the housing of the cooking appliance or on the contact section.

A plurality of pin devices and corresponding through openings are preferably provided, the pin devices being formed essentially simultaneously. Here, in particular, a tool provided specifically for this purpose can be used to fix the diaphragm device to the contact section for the diaphragm device in one work step. Through a common reshaping of several pin devices, a particularly quick and effective attachment of the diaphragm device to the contact section can be achieved.

The cooking device according to the invention comprises at least one housing device, at least one cooking space with at least one cooking space opening, at least one of the cooking space opening closing cooking chamber door and at least one panel device, which borders the cooking chamber opening at least in sections. The housing device has at least one contact section for the diaphragm device and the cooking space can be supplied with steam. The panel device is made of plastic at least in sections, and at least one sealing device is also provided, which essentially completely interrupts the contact between the cooking chamber and the panel device when the cooking chamber door is closed. At least one pin device is provided on a rear side of the diaphragm device and the contact section has at least one corresponding through opening for the diaphragm device. The pin device is guided through the through opening and deformed, so that the diaphragm device is at least sectionally firmly connected to the contact section.

The panel device is designed in particular as a front panel of the housing device, which borders the cooking space or the cooking space opening and can be seen as soon as the cooking space door is opened. The front panel can preferably also serve as a contact surface of the oven door when it is closed.

According to the invention, the front panel is made at least in sections and in particular completely from plastic. In this way, a front panel can be made of a material that is particularly easy to process and also allows complex shapes.

The sealing device consists at least in sections of silicone or is preferably made entirely of silicone. The sealing device is particularly preferably designed such that it allows vapor-tight shielding between the cooking space and the cooking space door. The sealing device is intended in particular to avoid direct contact between steam and plastic or the diaphragm device.

The cooking device according to the invention offers many advantages. A significant advantage is that the diaphragm device is made of plastic. This makes it possible that even complex shapes can be taken into account when manufacturing the diaphragm device. For example, various components can also be manufactured in one piece with the front panel or the panel device, so that it is no longer necessary to subsequently attach these components.

Furthermore, an aperture device made of plastic is also produced, for example, by injection molding, so that almost any shape can be provided easily and inexpensively.

The sealing device is preferably designed to run all the way around the cooking space opening. Such a configuration ensures that steam present in the cooking space cannot come into contact with the diaphragm device.

The contact section for the diaphragm device is particularly preferably provided at least in sections by at least one reshaping of at least one cooking chamber wall. Multiple reshaping is particularly advantageous here. The shaping of a cooking chamber wall as a contact section already achieves a certain thermal decoupling between the cooking chamber wall and the contact section for the diaphragm device.

In expedient further developments, the sealing device is arranged at least in sections between the contact section and the diaphragm device. As a result, an even better thermal decoupling between the cooking space jacket or the cooking space wall and the diaphragm device is achieved.

In advantageous configurations, at least one holding section for the sealing device is provided on the contact section for the diaphragm device and / or on the diaphragm device itself. Such a holding section can be provided, for example, by at least one extension and / or a shaping, onto which the sealing device can be pushed or plugged.

At least one undercut is preferably provided on the diaphragm device, in which the sealing device engages at least in sections in the installed state. A secure hold of the sealing device on the diaphragm device can be ensured via such an undercut. In addition, it is possible for a sealing device to be preinstalled on the front panel or the panel device before the panel device is attached to the cooking appliance.

The sealing device is preferably made at least in sections in one piece with the diaphragm device. This is possible, in particular, using a 2-component process in which different types of plastic are permanently bonded to one another.

It is particularly preferred that at least one functional device is made at least in one piece with the diaphragm device. By designing the aperture device Plastic, for example, makes it possible to manufacture door hinge bearings, receptacles for switches and other functional components in one piece with the cover device. As a result, the manufacturing costs and the manufacturing outlay are reduced, since the diaphragm device can be produced in one piece with functional devices, for example via an injection molding process.

In advantageous configurations, at least one pin device is provided on the rear side of the diaphragm device and the contact section has at least one corresponding through opening. The pin device is guided through the through opening and reshaped in order to ensure a secure hold of the diaphragm device on the contact section. In such an embodiment, an, for example, substantially cylindrical extension on the rear of the diaphragm device can be passed through the through opening in the contact section for the diaphragm device and then pressed flat. This creates a kind of mushroom head, which leads to a deformation that causes a partial expansion like in a riveting process. For example, by hot stamping the pin device, a secure connection can be established between the diaphragm device and the contact section.

In preferred configurations, at least one decorative panel covers the panel device at least in sections. This makes it possible for the diaphragm device made of plastic to be visually covered by a decorative device. Such a decorative panel can in particular be made at least in sections from stainless steel or have a stainless steel look. In this way, the advantages of an aperture device made of plastic can be used, whereby an overall impression of high quality can nevertheless be achieved by the decorative panel used.

The aperture device is particularly preferably at least partially translucent and at least one illumination device is arranged at least partially behind the aperture device. This makes it possible for an illuminated front frame to be seen when the cooking chamber door is open, as a result of which a particularly advantageous appearance of the cooking appliance can be achieved.

Further advantages and features of the present invention result from the exemplary embodiments, which are explained below with reference to the accompanying figures.
