TOUCH SENSOR ASSEMBLY AND REFRIGERATOR DOOR INCLUDING A TOUCH SENSOR ASSEMBLY
FIG19 is a perspective view illustrating the cover in FIG12
A plurality of coupling hooks 210 that extend in a thickness-wise or depth direction (i.e., a front-rear direction) of the cover 200-1 may be provided at lateral (i.e., left and right) sides of the cover 200-1. The plurality of coupling hooks 210 may be formed in locations corresponding to positions of a plurality of hook grooves 315 (FIG19) of the display cover 30-1 (FIG19). The plurality of coupling hooks 210 may be provided in locations that face each other on the left and right sides of the cover 200-1 and may be regularly spaced apart from each other in the up-down (i.e., length-wise) direction. A plurality of support hooks or clips 380 may have a different shape from the support hooks 318 in FIG19 provided in the display cover 30-1 and may be provided at side edges of the accommodation portion 311. The plurality of support hooks 380 may be provided in locations that face or align with each other on left and right sides of the accommodation portion 311 and may be spaced apart from each other by predetermined intervals in the up-down direction to evenly support the cover 200-2. The support hooks 380 may be bent or curved.
