In an appliance having a nominally required product load and control components for controlling functions not directly related to those of the nominally required product load, the control components operating at voltages which are relatively low in comparison with those utilized by the nominally required product load, a portion of the nominally required product load is connected in series with the control components to serve as a voltage step down circuit whose output corresponds to the relatively low voltages required by the control components. The control components may include those used to operate a refrigerator door ice and water dispenser, and may provide additional accessory functions such as a toggle operated childproof door lock and display or night lighting, while the portion of the nominally required product load carrying circuit used in the power supply may include a heater coil of the type conventionally provided in the area of the dispenser ice chute for preventing moisture condensation on the dispenser surfaces.
Dans un appareil ayant une charge nominale, dans lequel des éléments de commande de fonctions non liées directement à celles de la charge nominale fonctionnent sous des tensions relativement basses par rapport à celles de la charge nominale, une partie de la charge nominale est connectée en série avec les éléments de commande afin de constituer un circuit abaisseur de tension dont la sortie correspond aux tensions relativement basses nécessaires aux éléments de commande. Les éléments de commande peuvent entre autres commander une distributrice de glace et d'eau incorporée à une porte de réfrigérateur, et remplir des fonctions accessoires, p. ex. verrou de porte à bascule à l'épreuve des enfants, éclairage d'étalage ou de nuit. La partie du circuit de charge nominale utilisée pour l'alimentation peut comprendre une bobine d'élément chauffant du type qu'utilisent habituellement les distributrices de glace, près de la chute de glace, pour empêcher la condensation d'humidité sur leurs parois.
