A plurality of touch sensors 712 may be disposed in the vertical direction, and may be disposed in each area between the plurality of support protrusions 722 and 723 . That is, the support protrusions 722 and 723 may be disposed above and below the position where the touch sensor 712 is mounted, and the pressure applied to the touch sensor 712 by the arrangement of the support protrusions 722 and 723 . may be concentrated in the center of the touch sensor 712 .

And, the touch PCB 71 is pressed forward by the elastic member 72 and further forward pressed by the support protrusions 722 and 723, so that the touch sensor 712 is more sensitive to the touch cover 73 . can be adhered to the back surface of Accordingly, the user's touch manipulation through the different touch cover 73 can be recognized more effectively.

The touch cover 73 may be formed to have a size corresponding to the opened front surface of the sensor assembly mounting part 34 , and the sensor assembly mounting part may be formed by cover hooks 732 formed on both sides of the touch cover 73 . (34) may be fixedly mounted to be movable in the front-rear direction.

Accordingly, in a state in which the touch PCB 71 is pressed and supported forward by the elastic member 72 , it can be more closely attached to the rear surface of the out plate 21 . In addition, the touch sensor 712 can be pressed more effectively while moving backward when the out plate 21 is pressed.

Also, a touch booster 731 may be disposed on the touch cover 73 . The touch booster 731 may be formed to be concentric with the central portion of the touch sensor 712 , and may be formed in front of the touch sensor 712 . In addition, a plurality of helical booster cutouts 731a are formed along the circumference of the touch booster 731 so that when pressure is applied to the touch booster 731 , the central portion of the touch booster 731 moves backward. can become That is, the touch booster 731 may be elastically deformed and moved backward by the booster cutout 731a, and may return to its original position when the user releases his/her hand.

In addition, a rearwardly protruding protrusion may be further formed in the center of the touch booster 731 . Accordingly, when the touch booster 731 is moved backward by a pressing operation of the out plate 21 , the touch sensor 712 . ) can be pressed more effectively.

Hereinafter, a state in which the display unit 211 is visualized in the refrigerator having the above structure will be described with reference to the drawings.

22 is a cross-sectional view 22-22' of FIG. 2 . And, FIG. 23 is a cross-sectional view 23-23' of FIG. 2 .
