Title
(EN) NEGATIVE PRESSURE SENSING FOR AN APPLIANCE DOOR CLOSURE
(FR) DÉTECTION DE PRESSION NÉGATIVE POUR FERMETURE DE PORTE D'APPAREIL
Abstract
(EN)
A system (10) for measuring and monitoring the closure of a refrigerated compartment (120) of an appliance (100) includes a controller (200) having at least one input and at least one output for receiving and providing electrical signals to a plurality of electrical components of the appliance (100). The system (10) includes a pressure sensor for monitoring the compartment (120) to detect the presence of a negative pressure pulse indicative of a compartment (120) closure.
(FR)
L'invention concerne un système (10) pour mesurer et surveiller la fermeture d'un compartiment réfrigéré (120) d'un appareil (100), lequel système comprend un dispositif de commande (200) ayant au moins une entrée et au moins une sortie pour recevoir et fournir des signaux électriques à une pluralité de composants électriques de l'appareil (100). Le système (10) comprend un capteur de pression pour surveiller le compartiment (120) pour détecter la présence d'une impulsion de pression négative indiquant une fermeture de compartiment (120).
