Device for indicating or monitoring or reporting melting phenomenon in domestic enclosure of freezer, has cylindrical bulb that is able to swivel to specific degree around axis perpendicular to its bigger length with its axis of symmetry

摘要

The device has a transparent principal cylindrical bulb into which an ecological volume of colored liquid (6) i.e. red aqueous solution of Azorubine with 0.5%, is introduced, and a piece of a solid is provided in the shape of an immersed snap ring (5) that follows displacement of the liquid. The transparent cylindrical bulb is able to swivel to 180 degree around an axis perpendicular to its bigger length with its axis of symmetry. The bulb is able to swivel freely around a crossing axis (1) that is screwed on its support of a standard suction cup (4) or ankle.
