A reflective film 51 is arranged on the inner surface side (back side) of the light guide section 5 . A vacuum insulation panel 14 is arranged on the inner surface side (back side) of the reflective film 51 .

For example, the Z-direction and Y-direction dimensions of the light guide section 50 and the reflective film 51 are optical parts that are substantially the same as or the same as the Z- and Y-direction dimensions of the liquid crystal display section 10 . For example, the upper light introduction end portion 52 of the light guide portion 50 faces the LED 31L of the light irradiation portion 31 . The Z-direction and Y-direction dimensions of the vacuum insulation panel 14 are slightly smaller than or the same as the Z- and Y-direction dimensions of the light guide section 50 and the reflective film 51 . Such a structure is the same for the door 7 as well.

A light irradiation unit 31 for irradiating the liquid crystal display units 10 and 11 with light is provided at a position different from the position of the vacuum heat insulation panel 14 . As a result, the light irradiation unit 31 can supply illumination light to the liquid crystal display units 10 and 11 even if the vacuum insulation panel 14 is present. The light irradiation section 31 can be used as a so-called edge light for illuminating the liquid crystal display sections 10 and 11 .

In the door 6, when each LED 31L of the light irradiation section 31 emits light along the Z1 direction, the light guide section 50 transmits the light from each LED 31L through the circuit board 12 having light transmittance to the liquid crystal display section. 10 to illuminate the liquid crystal display section 10 from the inner surface side. At this time, the light from each LED 31L is reflected toward the liquid crystal display section 10 by the reflective film 51 . As a result, the liquid crystal display section 10 can evenly receive the light from the LEDs 31L of the light irradiation section 31 as edge lights from the inner surface side, so that the entire surface of the liquid crystal display section 10 can be displayed evenly. The same applies to the door 7 as well.

1 and 2 are the same as the structural example of the door 7, the corresponding parts of the door 7 are denoted by the same reference numerals as the corresponding parts of the door 6. The explanation is omitted.

Heat generated by the liquid crystal display units 10 and 11 and their circuit boards is conducted backward, but this heat can be blocked (stopped) by the vacuum heat insulating panel 14 . Therefore, the heat generated by the liquid crystal display units 10 and 11 and their circuit boards 12 and 13 and conducted backward and the heat blocked (stopped) by the vacuum heat insulation panel 14 are accumulated in the vacuum heat insulation panel 14 . The heat accumulated in the vacuum insulation panel 14 in this way moves to the lower side of the doors 6 and 7 and to the left and right fixing members 22, 23 and 24, and through the holes 25 for heat dissipation of the fixing members 22, 23 and 24, It can be released outside the doors 6 and 7 .

For this reason, it is not necessary to increase the heat insulating thickness of the heat insulating material 3 in the doors 6, 7 shown in FIG. , 11 are arranged respectively, it is possible to contribute to miniaturization of the refrigerator while ensuring the volume of the inside of the refrigerator. Since the heat generated by the liquid crystal display units 10 and 11 and their circuit boards 12 and 13 and the heat blocked by the vacuum insulation panel 14 do not leak into the freezer compartment 4 and the refrigerator compartment 5, the temperature inside the freezer is can be easily maintained, and an increase in power consumption can be avoided.
