Description

Stove and range hood assembly

The invention relates to a stove frame and range hood assembly.

The kitchen usually includes a stove and a range hood placed above the stove to extract the smoke generated during cooking.

Cooker hoods built into the operating surface supporting the hob are known. These range hoods are called downdraft range hoods because they move vertically. The downdraft range hood can be moved from a lowered position flush with the operating surface to a raised position. In the raised position, the extraction opening of the range hood protrudes relative to the operating surface in the upper position and is guided to the stove frame for extraction. smoke.

This type of suction range hood suffers from some disadvantages. The range hood protruding from the hob in the upper position is an obstruction and such a hob is not suitable for installation in an island kitchen. The installation and maintenance of range hoods are quite complicated. The range hood is placed on only one side of the hob, thus providing uneven extraction.

DE102015104470 discloses a hob with at least one heating surface unit that can be lowered in order to heat containers.

It is an object of the present invention to eliminate the disadvantages of the prior art by providing an efficient and aesthetically pleasing hob and range hood assembly.

Another object of the present invention is to provide such a stove rack and range hood assembly that is reliable, practical, multi-functional and easy to manufacture and install.

These objects are achieved according to the invention by the characteristics of independent claim 1.

Advantageous embodiments of the invention emerge from the accompanying claims.

The stove and range hood assembly of the present invention is defined in claim 1.

This type of stove rack and range hood assembly has the following advantages.

The range hood does not protrude from the hob and does not form an obstruction. Therefore, the stove rack can be accessed from four sides, and the stove rack and range hood assembly is suitable for installation in an island kitchen.

Installation and maintenance are simple because the range hood is fixed.

When the hob is lowered, there are at least two extraction openings of the range hood on two opposite sides of the hob, thus providing efficient and even extraction.
