CA 2747764

A heated counter for service of hot food has one or more hotplates (12, 14, 16), a light source (32, 34, 36) illuminating each hotplate and a number of light sensors (24) below each hotplate. When a sensor is obscured by a dish of food, power is supplied to that hotplate, and when no sensor is obscured, that hotplate is kept in stand-by mode.

La présente invention concerne un comptoir chauffé pour servir des aliments chauds qui comporte une ou plusieurs plaques chauffantes, une source lumineuse qui éclaire chaque plaque chauffante et un nombre de capteur de lumière en dessous de chaque plaque chauffante. Lorsqu'un capteur est obscurci par un plat d'aliments, de l'électricité est fournie à cette plaque chauffante, et lorsqu'aucun capteur n'est obscurci, cette plaque chauffante est maintenue en mode d'attente.
