When the vacuum heat insulating material 211 a is provided, the cold air circulating in the storage room 120 is less likely to be warmed by the temperature of the disaster prevention unit housing section 200 . For example, when the vacuum heat insulating material 211a is provided, when the backup power supply device 300 of the disaster prevention unit housing section 200 described later generates heat, the heat of the backup power supply device 300 can be suppressed from being transmitted to the cool air in the storage room 120. can. However, all or part of the partition wall 210 does not necessarily have heat insulation, and may be made of a material that does not have heat insulation.

Moreover, the partition wall 210 may have a reinforcing member 211b. The reinforcing member 211b is, for example, a member having higher rigidity than the inner box upper portion 210a, the inner box lower portion 210b, and the heat insulating material 210c, and is, for example, a metal member. The reinforcement member 211b is provided, for example, substantially parallel to the upper surface of the partition wall 210, and is arranged between the inner box upper portion 210a and the heat insulating material 210c. The reinforcing member 211b extends over at least a portion of the left side wall 113 and at least a portion of the right side wall 114 . When the reinforcing member 211b is provided, the load of the disaster prevention unit housing portion 200 can be easily supported by the left side wall 113 and the right side wall 114. As shown in FIG. However, the reinforcing member 211b is not an essential component, and may be omitted if sufficient rigidity is ensured.

Next, the members arranged in the storage chamber S of the disaster prevention unit storage section 200 will be described. In this embodiment, the storage chamber S includes a standby power source storage chamber (backup power source storage space) PS in which the standby power supply device 300 is stored, and an emergency supply storage chamber (disaster prevention supply storage space) GS in which the emergency supplies 700 are stored. including.

In the case where the standby power supply device 300 can be charged by being supplied to the device 300 (for example, the AC power is supplied as it is), and in the case where the electric power supplied to the refrigerator main body 100 from the commercial power supply P is the desired electric power in the refrigerator main body 100. This includes the case where the backup power supply device 300 can be charged by being converted into (for example, DC power) and supplied to the backup power supply device 300 . In other words, the standby power supply device 300 may be electrically connected to the commercial power supply P without going through the power supply circuit unit 180 of the refrigerator main body 100 , and may be electrically connected to the commercial power supply P through the power supply circuit unit 180 of the refrigerator main body 100 . may be directly connected.

Further, in this specification, the phrases "charging possible by supplying power from the commercial power supply P through the refrigerator main body 100" and "charging possible by supplying power from the refrigerator main body 100" refer to "charging possible by supplying power from the commercial power supply P to the refrigerator main body It is used in the same sense as "chargeable using part of the power supplied to 100". That is, these expressions can be read interchangeably.

In this embodiment, at least a portion of the standby power supply device 300 can be used separately from the refrigerator body 100 as a portable power supply. In this specification, "separable from the refrigerator main body 100 and usable" and "separable from the refrigerator main body 100" mean that the refrigerator main body 100 can be separated from the heat insulating housing 110 and carried to a location different from the installation location of the refrigerator main body 100 for use. means that Also, the term “portable power source” broadly means a portable power source, including a relatively small mobile battery.
