The front surface of the door 12 is covered with a glass plate 19, and the peripheral surface and the back surface are covered with a panel 12a made of a plurality of resin molded products. The storage chamber 20 adjacent to the back surface of the glass plate 19 has an opening 20a (see FIG. 4) on the left side, and a wall surface is formed by a box-shaped cover 21 made of a resin molded product. Then, the space surrounded by the glass plate 19 and the panel 12 a is filled with the foam heat insulating material 18, and the outer surface of the cover 21 is fixed to the foam heat insulating material 18.

  Thereby, the glass plate 19 and the cover 21 are integrated, and the inside of the storage chamber 20 is isolated from the foam heat insulating material 18 by the cover 21. At this time, the interior of the door 12 is prevented from being visually recognized by a coating film (not shown) formed on the back surface of the glass plate 19 and the front surface of the door 12 is beautifully dressed. Further, the coating film is not formed on the portion of the glass plate 19 facing the cover 21, and the interior of the door 12 is prevented from being visually recognized by a resin sheet 22, which will be described in detail later, so that the front of the door 12 is beautifully decorated.

  FIG. 3 is an exploded perspective view of the operation unit 30. The operation unit 30 has an LED substrate 33 and a switch substrate 34 held by a substrate holder 32 made of a resin molded product. The LED board 33 has a plurality of LEDs 33a mounted on the top and a connector 33b attached to the bottom. The switch board 34 is provided with a plurality of detectors 36 for detecting capacitance, and a touch panel is formed on the front surface of the operation unit 30. Lead wires (not shown) formed of a flexible substrate are led out on the back surface of the switch substrate 34.

  The substrate holder 32 is formed with a recess 32d (see FIG. 2) for housing the LED substrate 33 on the back surface, and a recess 32a for housing the switch substrate 34 at the lower part of the front surface. A plurality of through holes 32 c into which the LEDs 33 a are inserted are provided in the upper part of the front surface of the substrate holder 32. A through hole 32b is provided in the back wall of the front recess 32a, and the lead wire of the switch board 34 is connected to the connector 33b of the LED board 33 through the through hole 32b.

  FIG. 4 is an exploded perspective view of the storage chamber 20 portion. As described above, the wall surface of the storage chamber 20 is formed by the cover 21 made of a resin molded product, and the opening 20a is provided on the left end surface of the door 12 (see FIG. 1). The operation unit 30 is inserted into the storage chamber 20 through the opening 20a, and the opening 20a is closed by a lid (not shown).

  The cover 21 has a front surface portion 21a that covers the front surface, a back surface portion 21b that covers the back surface, and a peripheral surface portion 21c that covers the top and bottom surfaces and the right side surface. The front portion 21a is provided with an extending portion 21d that extends in the vertical direction of the storage chamber 20 and is formed over the upper and lower ends of the door 12 (see FIG. 1). A resin sheet 22 is disposed on the front surface of the front surface portion 21a. The resin sheet 22 is formed so as to extend over the extended portion 21d, and is disposed over the upper and lower ends of the door 12 (see FIG. 1).

  The front portion 21a is provided with a plurality of holes 21g facing the LED 33a. A plurality of insertion holes 21e facing the detector 36 are opened below the hole 21g. The conductive member 23 is inserted through the insertion hole 21e. As a result, the conductive member 23 is disposed opposite to the detector 36. The front surface of the conductive member 23 is covered with the resin sheet 22. The conductive member 23 is formed of metal, metal-plated resin, conductive resin, conductive rubber, or the like.

  FIG. 5 shows a side sectional view of the conductive member 23. A counterbore 21f is formed in the insertion hole 21e of the cover 21 on the glass plate 19 side. The conductive member 23 has a flange portion 23a having an enlarged diameter that comes into contact with the seating surface of the counterbore 21f. The conductive member 23 is sandwiched between the glass plate 19 and the cover 21 by the filling of the foam heat insulating material 18 (see FIG. 2), and is disposed opposite to the glass plate 19 through the resin sheet 22 (see FIG. 4).

  At this time, the thickness t of the flange 23a may be formed larger than the depth d of the counterbore 21f. Thereby, the conductive member 23 can be reliably brought into close contact with the back surface of the glass plate 19 via the resin sheet 22.

  In FIG. 4, a plurality of marks 22 a facing the hole 21 g and a plurality of marks 22 b facing the conductive member 23 are provided on the resin sheet 22. The mark 22a is illuminated from behind by an LED 33a that lights up in accordance with the operation mode. A mark 22b indicates a pressed portion of the detector 36 forming the touch panel.

  When the foam insulation 18 is filled in the door 12, the cover 21 and the glass plate 19 in which the conductive member 23 and the resin sheet 22 are arranged on the front surface portion 21a are integrated. At this time, the front surface of the storage chamber 20 is covered with the front surface portion 21 a of the cover 21. For this reason, it can prevent that a foreign material adheres to the back side of the glass plate 19 which faced the storage chamber 20 after filling with the foam heat insulating material 18.

  When the mark 22b on the resin sheet 22 is pressed through the glass plate 19, a change in capacitance is detected by the detector 36 via the conductive member 23 in contact with the back surface of the glass plate 19 with the resin sheet 22 interposed therebetween. Is done. As a result, a predetermined operation mode is executed, and the LED 33a is lit corresponding to the operation mode. The corresponding mark 22a is illuminated by the lighting of the LED 33a, and the operating state is notified. The conductive member 23 may be close to the back surface of the glass plate 19.

  According to this embodiment, the cover 21 forming the wall surface of the storage chamber 20 of the operation unit 30 having a touch panel has the front surface portion 21a facing the glass plate 19 and is integrated with the glass plate 19 by filling the foam heat insulating material 18. Is done. An insertion hole 21e is opened in the front surface portion 21a of the cover 21, and the conductive member 23 facing the detector 36 of the touch panel is inserted therethrough.

  For this reason, the back surface of the glass plate 19 facing the storage chamber 20 after filling the foam heat insulating material 18 is covered with the front surface portion 21a of the cover 21, and adhesion of foreign matters on the back surface of the glass plate 19 is prevented. Therefore, the yield of the refrigerator 1 can be improved. In addition, the touch panel on the front surface of the operation unit 30 can be reliably operated through the glass plate 19 by the conductive member 23 disposed on the front surface portion 21 a of the cover 21.

  Moreover, the resin sheet 22 which covers the conductive member 23 and indicates the pressing position of the touch panel is disposed on the front surface of the front surface portion 21a. Thereby, the visual recognition of the electrically-conductive member 23 can be prevented and the beauty | look of the refrigerator 1 can be improved.

  Moreover, the insertion hole 21e provided in the front part 21a of the cover 21 has a counterbore 21f on the glass plate 19 side, and the conductive member 23 has a flange 23a that abuts against the seating surface of the counterbore 21f. As a result, the conductive member 23 is sandwiched between the cover 21 and the glass plate 19, and the conductive member 23 can be easily prevented from falling off.

  Further, when the thickness t of the collar portion 23a is larger than the depth d of the counterbore 21f, the conductive member 23 can be brought into close contact with the back side of the glass plate 19 and the touch panel can be operated reliably.

  In this embodiment, the storage chamber 20 is formed by opening the opening 20a on the side surface of the door 12. However, the storage chamber 20 may be formed by opening the opening 20a on the upper surface or the lower surface of the door 12. A storage chamber 20 may be formed in the door 11.

  According to this invention, it can utilize for the refrigerator which provided the touch panel in the door which distribute | arranged the glass plate to the front.
