Abstract

The invention relates to an optical system for an induction cooking device with at least one induction coil (2) and an at least partially transparent or semi-transparent top plate (3), the optical system (10) comprising at least one light source (11) to be arranged in a central area of said induction coil (2) in order to provide light through a central opening (2.1) of said induction coil (2), light deflecting means (12) configured to receive light from the light source (11) and provide said light at one or more openings (12.1) and light guiding means (13) for guiding light provided at said one or more openings (12.1) in an area between the upper side of the induction coil (2) and the lower side of the top plate (3), said light guiding means (13) being configured to guide the light into aspace between the induction coil (2) and the top plate (3) and provide a light indicator at the top side of the top plate (3).

Description

[0001] The present invention generally relates to the field of induction cooktops. More particularly, the present invention relates to an optical system for providing a light indicator at a top plate of an induction cooktop. Background technique [0002] Induction cooktops for preparing food are well known in the art. Induction cooktops typically include at least one induction coil placed below the top plate to heat the cookware. In widely used configurations, the top plate is transparent or translucent and may be made of glass-ceramic material. [0003] European patent application EP 2 648 478 A1 discloses a lighting device for cooking hobs. The cooking hob comprises a cooking zone element having a central cutout, said lighting device being arranged below the central cutout for illuminating a central part of the cooking zone heated by said cooking zone element. [0004] However, this known solution is disadvantageous because the size and extent of the cooking zone elements...
