BRIEF SUMMARY
DESCRIPTION
The invention concerns a microwave device for the preparation of food with a lower part designed for holding an easily handled container in the form of a pot, bowl or pan containing food, surrounding at least one part of the cooking space and independent of the basic device composed of a lower part, an upper part fitting as a cover over the lower part in operating position and a connecting column, joining the lower and upper part, which in operating position rests tightly sealing against the upper part surrounding the cooking space with its upper rim in order to prevent the leaking of microwave emition.
Such a microwave device is known from DE-OS No. 30 34 962. There, the container is either pushed into operating position in guides on the upper part or set onto a plate of the lower part that can be raised and lowered. In both cases considerable manipulations are needed in order to get the container into operating position. In addition, the container is no longer or only with difficulty accessible from above, once it has been pushed or set into the basic device, which is a particular disadvantage if the support surface for the container in the lower part is formed by a heating plate, so that the food in the microwave device can not only be heated by microwave, but also, simultaneously or independently, heated by the heating plate, and for which purpose the inside of the container should be easily accessible.
It is the task of the current invention to construct a microwave device of the above cited type which provides simpler handling and better access to the container in its position on the support surface of the lower part.
In the microwave device of the type cited in the beginning, this problem is solved, according to the invention, essentially by the fact that the lower part and the upper part are hinged together in such a manner that, based on a relative motion by lower part and upper part into a closed operating position, the upper part rests against the rim of the container and, in the open position, releases the container for removal from the basic device. Thus, in the open position, the container is simply set onto the designated part of the support surface of the lower part.
When the foods contained in the container are supposed to be treated by microwaves, the upper part is simply flipped downward into the operating position, whereby it rests against the upper rim of the container and thus locks the cooking area against the leakage of microwaves and also against the free release of steam. Should the container have to be removed from the basic device, further additions to be added to the dish or the food have to be stirred, the upper part simply has to be flipped up so that the inside of the container is accessible and the container can also be easily removed from the basic device. The upper part remains in the open position if the support suface for the container in the lower part is formed by a heating plate and is only to be used as heating plate. In this manner the microwave device is doubly useful with easy access to the container.
The device cited in the beginning is relatively voluminous as its outer dimensions are fixed, regardless if the container is inserted into the basic device or not. For this reason it is another goal of the present invention that, in the resting position of its parts, i.e., when it is not supposed to be used, it can be stored in a space saving manner. This is attained due to a special characteristic of the invention in which the lower part and upper part are hinged in such a manner that, by a relative tilting of lower and upper part, the upper part--with removed container--will rest, or almost rest, against the lower part in the area of the support surface. Here too, use is made of the basic idea of the pivotability of the upper part against the lower part; however, care has been taken that the upper part, relative to the lower part, can be brought not only into a closed operating position in which the upper part rests against the rim of the container, b
