AI Technical Summary

Benefits of technology

The invention is about a hot plate and a hob that solve problems in the prior art and improve their function. The hot plate has a planar upper side with a concavely depressed internal region to prevent cooking vessels from bearing on it. The hob has a counterbearing that engages at least three bearing points on the hot plate, which are distributed in a way that prevents bending or buckling of the hot-plate body. This hot plate design is advantageous for round or square basic shapes, and can be used with abnormal hot plates that have a normal upper side. The technical effects of the invention are improved heat transfer and better planarity of the hot-plate body.

Problems solved by technology

However, a very slow or sluggish heating behavior, respectively, and a sub-optimal energy efficiency of the hot plates are seen as disadvantageous.

Embodiment Construction

[0033]A right-hand region of a hot plate 11 according to the invention that has a hot-plate body 13 is illustrated in a section in FIG. 1. The hot-plate body 13 has a substantially flat upper side 15 which however does not inevitably have to be completely planar by any means. An encircling planar region 17 which is configured as a circular ring having a consistent width, the latter being indicated thereabove by the short lines, is provided in the external region. This width may be 10 mm. The planar region 17 is completely planar, or lies completely in one plane, or in other words does not project beyond a plane on which the planar region 17 nevertheless chiefly or largely or completely bears, respectively, or which plane the planar region 17 defines, respectively. This means that micro-depressions, a rough surface, or concentric channels that are usually created by rotating final machining of a casting of which the hot-plate body 13 is composed, having a depth of significantly less ...

Abstract

A hot plate has a hot-plate body from metal, having an upper side and a lower side. At least one heating element is disposed on the lower side of the hot-plate body. The upper side of the hot-plate body is configured so as to be flat, for setting up a cooking vessel to be heated. The upper side of the hot-plate body in an external region has an encircling planar region which lies in a plane, or which forms a plane, respectively, wherein the upper side, radially within the planar region, has at least one internal region which is concavely depressed, which in relation to the planar region is depressed by between 0.05 mm and 1 mm.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to European Application No. EP 16155081.9, filed Feb. 10, 2016, the contents of which are hereby incorporated herein in its entirety by reference.TECHNOLOGICAL FIELD[0002]The invention relates to a hot plate, and to a hob having a hot plate.BACKGROUND[0003]Hot plates for the use in hobs or stoves for cooking, respectively, have been known for a long time, for example from EP 957661 B1 or U.S. Pat. No. 5,010,235. Hot plates of this type have a hot-plate body from a metal casting or steel, on the upper side of which a cooking vessel to be heated is set up. Heating helices in an insulation material are disposed as heating elements in depressions that are separated by webs on a lower side of the hot-plate body. Such a hot plate is usually inserted from above into a hot-plate opening in a hob plate of a hob, and by way of a projecting periphery bears thereon. From below, the hot plate is covered by a cover disk...
