Water Level Sensor for Steam Generator

Abstract

A separation-type water level sensor, and a steam generator ( 15 ) of a washing drying machine having the same. The steam generator ( 150 ) includes a case storing water for generating steam; and a separation-type water level sensor comprising a common electrode assembly ( 160 ) comprising a water common electrode ( 162 ) and a common electrode housing ( 161 ), and inserted into the case; and a first water level electrode assembly ( 170 ) comprising a first water level electrode ( 172 ) and a first water level electrode housing ( 171 ), separated form the common electrode assembly ( 160 ), and inserted into the case.

1 . A steam generator of a washing or drying machine comprising: 
 a case storing water for generating steam; and    a separation-type water level sensor comprising:    a common electrode assembly comprising a common electrode and a common electrode housing, and inserted into the case; and    a first water level electrode assembly comprising a first water level electrode and    a first water level electrode housing, separated from the common electrode assembly, and inserted into the case.    
   
   
       2 . The steam generator as set forth in  claim 1 , wherein the common electrode assembly further comprises a second water level electrode.  
   
   
       3 . The steam generator as set forth in  claim 1 , wherein each of the common electrode assembly and the first water level electrode assembly has a socket so that an external plug is inserted into the socket to be electrically connected to the common electrode assembly and the first water level electrode assembly.  
   
   
       4 . The steam generator as set forth in  claim 1 , further comprising a heater installed in the case storing the water, 
 wherein the first water level electrode senses a level of water out of which at least a part of the heater is exposed.    
   
   
       5 . A separation-type water level sensor for a steam generator comprising: 
 a common electrode assembly comprising a common electrode and a common electrode housing; and    a first water level electrode assembly separated from the common electrode assembly, and comprising a first water level electrode and a first water level electrode housing.    
   
   
       6 . The separation-type water level sensor as set forth in  claim 5 , wherein the common electrode assembly further comprises a second water level electrode.
