Abstract

A door for ovens used in kitchens for cooking meals, characterized in that, it comprises a body (1) bearing the arrangements for opening and closing said door thereon, at least one wedge (3), which is mounted on the oven door by means of the body (1) and pivotally mounted to the hinge, mounted on the oven housing, and at least one lock plate (5) fixing the hinge to the wedge (3).

Description

Scope of the Invention

Prevent invention relates to ovens that enable cooking meals and that are used in all kitchens.
Said invention particularly relates to a door hinge that enables the front doors to be opened and closed easily, without noise and friction.

State of the Art

Today, ovens, which are a product from white goods range, are being used for cooking meals and especially where the meals are desired to be cooked in a tray. Ovens are products, which enables the large meal positioning materials, such as trays, to be located and the heat to be dissipated to everywhere homogenously.
Ovens show differences according to their visual structure, usage differences and systematically features. Oven doors take precedence among the parts that show differences in terms of the system. Present oven doors also show differences in terms of easy opening and closing, advantages and disadvantages they provide to the user and again the system.
One of the most serious problems experienced about the present oven doors is that the door makes too much noise and more strength is expended in order to open and close the doors related to before. Other problems are respectively, that the doors do not close completely and, as a manifestation of that, the heat escapes to outside. Escape of the heat causes heat losses and extra energy consumption.

Brief description of the invention

The object of the invention is to have the hinge that enables the front door of the oven to be opened and closed to work noiselessly, to minimize the friction of the working parts and to hold the door in balance during opening angles.
One of the object of the invention is to close the door completely by means of the hinge system and hence to avoid the heat losses and to provide energy savings.
Another object of the invention is that it may be easily mounted to the oven door and oven body and it has a resistant and tough structure against possible blows that may come from the outside.
Another object of the invention is that, for the motions of the hinge within the system during working may take place in a narrower area, a wider area is not allocated for the big spring holder and the tight press force is provided to the required seal by means of two small reel springs and having the big spring holder worked in contact with the reel, the motion is directed to the lower side and it is enabled to the empty space in the lower side to be used.

Detailed Description of the Invention

In figure 1 is depicted the dismounted three dimension view of the oven hinge. The hinge comprises a body (1), spring holder with reel (2), wedge (3), pipe pin (4), lock plate (5), big spring holder (6), claw (7), hooked spring (8), reel spring (9), plastic reel (10) and rivets (11). And in figure 2 is depicted the mounted two dimension view of the hinge.
According to the features of the oven door, the hinge may be mounted on the mounting area by means of one or several screws. By means of two different spring systems, namely hooked spring (8) and reel spring (9) groups, it differentiates the forces applied on the closing area between 0 and 24 degrees and on the opening are between 24 and 86 degrees and also is a single wedged and single pivoted hinge that enables the proper balancing of the door.
Following the hinge configuration has been mounted on the cover, it may be easily mounted into its hinge opposite slot, which has been beforehand mounted on the oven body by means of the hinge wedge (3) and it may be fixed into the hinge opposite slot by means of the lock plate (5).
The pipe pin (4), which bears the rotating pivot of the hinge and which is on the rotating pivot of the hinge body may be mounted on the wedge (3). In addition, the lock plate (5), which enables the task of fixing the hinge to the wedge (3), is mounted. To one end of the hooked spring (8), which enables the door to stand balanced between 24 and 86 degrees, the big spring holder (6) is mounted. And the other end of the big spring holder (6) is mounted on the wedge (3).
The other end of the hooked spring (8) is mounted on the hinge body (1) by means of the claw (7). The reel spring, which allows the hinge to stand at 24 degrees when it is in semi-open position and the door to press on the seal on the oven body tightly, is mounted on the hinge body (1) along with the spring holder with reel (2) and plastic reel (10). Rivets (11) are being used as a connector in the mounting process.
The oven, on which the hinges have been mounted, may hang on in 24 degrees semi-open position, may be opened and closed with a balance between 24 and 86 degrees and also, it may be opened and closed for 20.000 times, which is the minimum lifespan of the hinge, without any problem.

Claims

An opening and closing door of the ovens used in kitchens for cooking meals, characterized in that, it comprises a body (1) bearing the arrangements for opening and closing said door thereon, at least one wedge (3), which is mounted on the oven door by means of the body (1) and pivotally mounted to the hinge, mounted on the oven body, and at least one lock plate (5) fixing the hinge to the wedge (3).
