TUCH SENSOR ASSEMBLY AND REFRIGERATOR DOOR WITH TUCH SENSOR ASSEMBLY

摘要

Provided are a touch sensor assembly and a refrigerator door including the touch sensor assembly, improved in a recognition rate of a touch sensor which detects deformation of an outer casing member occurred when operating an operation portion by a touch. The present invention relates to the touch sensor assembly which includes: a sensor housing mounted in a rear surface of an outer casing member of a household appliance having an operation portion displayed thereon to be operated by a user through a touch; a sensor printed circuit board (PCB) installed in the inside of the sensor housing; a sensor hole formed through the sensor PCB to correspond to a position of the operation portion; and a touch sensor mounted at the sensor hole for detecting displacement of the outer casing member due to a touch operation on the outer casing member, wherein the sensor hole is smaller than a size of the touch sensor, thereby being blocked by the touch sensor and supporting a circumference of the touch sensor.
