PURPOSE: To obtain the structure of a conductivity sensor for detecting the degree of dirt, the degree of rinsing, the degree of dehydratiom, etc., of clothes at the time of washing, and setting each optimal time, the circuit for driving or detecting this structure and the fitting structure of the sensor.
CONSTITUTION: 1. The fitting position of a sensor: The through-hole is provided on the outside peripheral surface of a bottom part of an outer tank, and it is assembled so that the highest part of the conductivity sensor does not protrude from the outside peripheral surface of the bottom part. 2. The sensor structure: The sensor case is divided into two chambers, an electrode plate is provided opposingly on one of them, electronic parts containing a transformer are provided on the other, and the whole substrate on which they are loaded is sealed with a cast molding agent such as methane, etc.
