Abstract
The present disclosure relates to food preparation apparatus with an electrical heating device comprising at least two electrical PTC thermistors for heating a food in a food preparation room, wherein the electrical PTC thermistors are electrically connected in parallel. The parallel-connected PTC thermistors are electrically connected to one another by one or more electrical bridges.
Claims24
A food preparation apparatus with an electrical heating device, the apparatus comprising
- at least two electrical PTC thermistors configured to heat a food in a food preparation chamber, the at least two electrical PTC thermistors being electrically connected in parallel,
- wherein the at least two PTC thermistors are electrically connected to one another by one or more electrical bridges;
- wherein the at least two PTC thermistors extend at least predominantly along a circular path.
A food preparation apparatus with an electrical heating device, the apparatus comprising:
- at least two electrical PTC thermistors configured to heat a food in a food preparation room, the at least two electrical PTC thermistors being electrically connected in parallel,
- wherein the at least two PTC thermistors are electrically connected to one another by one or more electrical bridges, and
- wherein the at least two PTC thermistors run parallel to one another.
A food preparation apparatus with an electrical heating device, the apparatus comprising:
- at least two electrical PTC thermistors configured to heat a food in a food preparation room, the at least two electrical PTC thermistors being electrically connected in parallel,
- wherein the at least two PTC thermistors are electrically connected to one another by one or more electrical bridges, and
- wherein PTC thermistors are present which comprise loops of different lengths.
A food preparation apparatus with an electrical heating device, the apparatus comprising:
- at least three electrical PTC thermistors configured to heat a food in a food preparation room, the at least three electrical PTC thermistors being electrically connected in parallel,
- wherein the at least three PTC thermistors are electrically connected to one another by one or more electrical bridges, and
- wherein the at least three PTC thermistors are arranged so as to provide (i) distances between the at least three PTC thermistors that are equal or (ii) distances between the at least three PTC thermistors, which extend at least predominantly in a circle, that decrease from the inside to the outside.
