Comparison Bosch PKE 611 BB2E black vs Bosch PKE 645 BB2E black

The presence of a metal frame in the design of the hob. Such a frame can be located both around the entire perimeter of the device (in most classic models) and only on one side (usually in domino hobs, see "Design" for more details). The frame plays an aesthetic role, allowing you to optimally fit the hob into the overall design of the kitchen. However, it can also perform a very practical function: to retain liquids spilt onto the surface. On the other hand, such protection also has disadvantages: it can be quite difficult to clean dirt near the frame, and the liquid retained on the hob can burn, making cleaning even more difficult. So in terms of cleaning, models without a frame are more convenient.

General dimensions of the device in width and depth. Depth, in this case, refers to the distance from the leading edge to the trailing edge (when viewed from the user's side). Note that the external dimensions of the hobs are often larger than the dimensions for embedding (see below).

The size of the opening that needs to be made in the kitchen countertop for the normal embedding of the hob. By default, the width and depth are indicated — the size of the opening along the front and side sides, respectively (when viewed from the user's side). Note that the dimensions of the hob itself are usually larger than the dimensions for embedding: when installed in an opening, the upper part of the surface rests on its edges, so that the device does not fall into the countertop.
