A control unit (3) for controlling the service functions of an electric household appliance (e.g. a refrigerator) is connected in series with a positive temperature coefficient (PTC) resisting unit (4) which, when supplied with electric current, generates sufficient heat to activate thermally activated actuating means (6) for selectively connecting/disconnecting respective auxiliary switches (9) of service loads (2) corresponding to the service functions of the electric household appliance. The thermally activated actuating means (6) include a temperature-deformable element (7) (e.g. a bimetallic plate), the deformation of which is transmitted by kinematic connecting means (10) to a camshaft (8), the cams (12) of which cooperate with the auxiliary switches (9) of the service loads (2) to selectively connect/disconnect the auxiliary switches.

L'invention concerne une unité de commande (3) destinée à régir les fonctions d'utilisation d'un appareil électroménager (par exemple un réfrigérateur), cette unité de commande étant montée en série avec une résistance (4) à coefficient de température positif (PTC) qui, alimentée en courant électrique, génère suffisamment de chaleur pour activer des organes d'actionnement (6) à activation thermique. On connecte/déconnecte ainsi sélectivement les interrupteurs auxiliaires respectifs (2) des charges utiles (2) correspondant aux fonctions d'utilisation dudit appareil électroménager. Les organes d'actionnement (6) à activation thermique comprennent notamment un élément thermodéformable (7)(par exemple une plaque bimétallique), dont la déformation est transmise par des organes de connexion cinématiques (10) à un arbre à cames (8), les cames (12) de cet arbre coopérant avec les interrupteurs auxiliaires (9) desdites charge utiles (2) afin de connecter/déconnecter sélectivement ces interrupteurs.
