Apparatus e.g. refrigerator, has operation unit operated by user for varying operational parameters outside apparatus, and detection element for releasing or blocking operating unit based on detected state of lock

摘要

The apparatus has an inner space for accommodating objects, and a door (10) for locking the inner space and locked by a lock (20). An operation unit (50) e.g. key board, is operated by a user for varying operational parameters outside the apparatus. A detection element detects a locking state of the lock and releases or blocks the operating unit based on the detected state of the lock. The detection element is designed as a switch (40) such as mechanical switch, electronic switch, door contact switch or a reed switch.
