ABSTRACT:
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to a cooking appliance door with a door base, to which a front panel is secured at the front of the cooking appliance door; and an inner panel is secured at the rear of the cooking appliance door. Cooking-product support brackets are fastened at the rear of to the cooking appliance door. The invention also relates to a cooking appliance equipped with such a door.
Such a cooking appliance door is known from German Patent DE 197 38 507 C1. An oven-muffle door has an inner pane of glass or vitreous material, to which there is or are fastened one or more cooking-product support brackets for cooking-product supports, for example baking sheets or grilling grids.
SUMMARY OF THE INVENTION
It is accordingly an object of the invention to provide a cooking appliance door which overcomes the disadvantages of the heretofore-known cooking appliance doors of this general type and which ensures a stable fastening of cooking-product support brackets.
With the foregoing and other objects in view there is provided, in accordance with the invention, a cooking appliance door, including a door base having a front side and a rear side; a front panel secured at the front side of the door base; an inner panel secured at the rear side of the door base and having openings formed therein; at least one cooking-product support bracket fastened at the rear side of the door base; and fastening elements extending through the openings formed in the inner panel for fastening the at least one cooking-product support bracket to the door base.
In other words, the object of the invention is achieved by the cooking-product support brackets being fastened directly to the door base through the use of fastening elements extending through openings in the inner pane. The door base is in this case made from a more stable and mechanically more resistant material than that of the inner pane, in order to be able without any problem without any problem to absorb forces without any problems. Such forces may occur when the cooking-product supports are hung onto the door base or door frame and are loaded. Metals and adequately mechanically and thermally resistant plastics are known in particular as materials for the door base, while a material typically used for the inner pane is glass. A further advantage according to the invention is that the direct fastening of the cooking-product support brackets to the door base or door frame allows the geometrical coordination of the cooking-product support brackets to one another as well as in relation to the door base and to the further door components fastened thereto to be carried out more precisely than in the case of a corresponding fastening to the inner pane.
To further improve the stability of the fastening of the cooking-product support bracket, the door base has a reinforcing plate, to which the cooking-product support bracket is additionally fastened.
A flexible spacing element is advantageously respectively secured between the inner pane and the cooking-product support bracket on the one hand and the door base on the other hand. As a result, particularly the fragile holes in the glass of the inner pane are flexibly covered and protected on both sides.
To simplify the construction of the door, the fastening elements secure an intermediate panel. The intermediate panel is provided between the front panel and the inner pane. This additional securing function can be performed particularly securely and in a way which is easy with regard to production and assembly. The fastening elements fasten at least one clamping strip to the door base. The at least one clamping strip secures the intermediate panel to the door base.
The cooking appliance door according to the invention is in particular advantageous for cooking appliances, such as baking ovens.
Other features which are considered as characteristic for the invention are set forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a cooking appliance and in particular a cooking appliance door, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
