摘要： Blocking device (1) comprising a body that can be fixed to a frame of the electric household appliance, laterally to a door to be blocked, a striker in the form of a striking plate (8) held sliding by the body perpendicular to the door and suited to cooperate in use with a notch (9) of the door, a pawl (10) for blocking the sliding of the striking plate, and control means (11) for selectively moving the pawl between an extracted position and a retracted position in/from a corresponding through perforation (13) in the striking plate; wherein said control means comprise an actuator (20) including an electrically conductive resistive wire (21) made of a shape memory alloy and able to vary its own length as an effect of its heating, means (22) for supplying controlled electric power to the resistive wire suited to determine its controlled variation in temperature by joule effect; and cam means (31) activated by said actuator (20) and acting on a bistable elastic device (40) directly controlling the position of said pawl (10).
摘要翻译：封闭装置（1）包括可以被固定到家用电器的框架的主体，横向于要被阻挡的门，撞击板（8）的形式的冲击板（8），其被身体垂直于门滑动并且适于与门的凹口（9）配合使用，用于阻挡撞击板的滑动的棘爪（10）以及用于在提取位置和缩回位置之间选择性地移动棘爪的控制装置（11） /从打击板中的对应的穿孔（13）其中所述控制装置包括致动器（20），其包括由形状记忆合金制成的能够改变其自身长度的导电电阻丝（21）作为其加热的影响，用于向电阻丝适用于通过焦耳效应确定其控制的温度变化; 以及由所述致动器（20）启动并且作用在直接控制所述棘爪（10）的位置的双稳态弹性装置（40）上的凸轮装置（31）。
