Title:
DOOR OPENING/CLOSING DETECTING DEVICE FOR STORAGE CHAMBER
Document Type and Number:
Japanese Patent JP2944816
Kind Code:
B2
Abstract:
PURPOSE: To perform manufacture of the door opening/closing detecting device of a storage chamber at a relatively low cost by utilizing the magnetic force of the magnet of a magnet gasket arranged to a door, in a device to detect opening/closing of the door of the storage chamber.
CONSTITUTION: A magnetic sensor 10 is disposed to the given portion of the edge part of the opening part of the storage chamber in a manner to be positioned facing a magnet 7 of a magnet gasket disposed to a door for opening/ closing a storage chamber and a pair of auxiliary plates 11 made of a magnetic substance are provided in a manner to nip the magnetic sensor 10 therebetween. When the door is brought into a closed state, the magnetic flux of the magnet 7 is interlinked with the magnetic sensor 10 through the auxiliary plate 11. At this time, the magnetic resistance of the magnet 7 against the magnetic sensor 10 is reduced by means of the auxiliary plate 11 and a large amount of a magnetic flux interlinked with the magnetic sensor 10 is ensured and along with the ensurance, the sensitivity of the magnetic sensor 10 can be increased.
