Abstract
(EN)
The present invention relates to an electric pot having an improved relay installation position. The disclosed electric pot comprises: a base including a first resistor connected between a first voltage regulator and any one of terminals of a first power module, and a comparator for comparing a voltage sensed between the first resistor and the connected terminal of the first power module with a preset reference voltage to control a switching operation of a relay unit; and a pot body including a second resistor disposed between a second power module and a buck converter and connected to a second voltage regulator in parallel, and a switch unit connected to the second resistor in series.

La présente invention concerne un contenant électrique ayant une position d'installation de relais améliorée. Le contenant électrique de l'invention comprend : une base comprenant une première résistance connectée entre un premier régulateur de tension et l'une quelconque des bornes d'un premier module d'alimentation, et un comparateur pour comparer une tension détectée entre la première résistance et la borne connectée du premier module d'alimentation à une tension de référence prédéfinie pour commander une opération de commutation d'une unité de relais ; et un corps de contenant comprenant une seconde résistance disposée entre un second module d'alimentation et un convertisseur abaisseur de tension et connectée à un second régulateur de tension en parallèle, et une unité de commutation connectée à la seconde résistance en série.
