Abstract

The invention relates to a washing machine and a distance sensor. According to one embodiment of the invention, the washing machine comprises the components of: a main body having a laundry loading hole formed therein;a door coupled to the main body to selectively open and close the laundry loading hole; at least one magnet provided in one of the door or the main body; and a plurality of reed sensors provided in the other of the door or the main body and configured to react to the at least one magnet.

Description

technical field [0001] The present invention relates to a washing machine, and more specifically, to a reed sensor that responds to a distance from a door that opens and closes a main body, and a distance sensor that responds to a distance from an object on which a magnet is placed . Background technique [0002] figure 1 Shows the relationship between a general reed sensor and a magnet. [0003] refer to figure 1 , The plurality of reeds 15 are made of a magnetic body. A part of the reed 15 is sealed inside the airtight glass tube 17 . Inert gas is filled inside the glass tube 17 . Two reeds 15 are arranged inside the glass tube 17 . [0004] The two reeds 15 are separated from each other with a predetermined interval. When the magnet 20 approaches, the reed 15 is magnetized. The two reeds 15 arranged on both sides are magnetized to have different magnetic properties. When the magnetic force overcomes the elastic force, the two reeds 15 are in contact with each oth...
