[4.2 Standby power supply]
[4.2.1 Overall Configuration of Standby Power Supply]
Next, the standby power supply device 300 will be described.
The standby power supply device 300 is a device that supplies electric power in place of the commercial power source P in the event of a power failure (when a disaster occurs). The standby power supply device 300 is electrically connected to the refrigerator main body 100 via an electrical connection member 403 such as a cable or busbar. Thus, the standby power supply device 300 is electrically connected to the commercial power source P via the electrical connection member 403, the power line 404 (see FIG. 6) inside the refrigerator main body 100, the power cable 185 of the refrigerator main body 100, and the like. .

The standby power supply device 300 can normally be charged using part of the power supplied from the commercial power source P to the refrigerator main body 100 . “Electricity supplied from commercial power supply P to refrigerator main body 100 ” broadly means, for example, electric power introduced from commercial power supply P into refrigerator main body 100 via power cable 185 of refrigerator main body 100 . “Charging is possible using part of the power supplied to the refrigerator main body 100 from the commercial power supply P” means that the power supplied from the commercial power supply P to the refrigerator main body 100 is not converted at all in the refrigerator main body 100 and is used as a backup power supply. 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, the phrases “separable from the refrigerator body 100 and usable” and “separable from the refrigerator body 100” mean that the refrigerator body 100 can be carried and used at a place different from the place where the refrigerator body 100 is installed. Also, the term “portable power source” broadly means a portable power source, including a relatively small mobile battery.

Here, an example of the standby power supply device 300 will be described in detail. The standby power supply device 300 has, for example, a standby power supply main body 300U, a main body connector 330, a fan 340, a power supply circuit section 350, a standby power supply overall control section 360, and a storage section 370 (see FIG. 14).

The first standby power supply case 311 is formed in a box shape, for example. The first standby power supply case 311 has a first end 311a and a second end 311b. The first end 311a is an end facing a body connector 330, which will be described later. The second end 311b is located opposite to the first end 311a and is the end facing the second standby power supply 320 .

The battery unit 312 is housed inside the first standby power supply case 311 . Battery unit 312 includes one or more secondary batteries. The secondary battery is, for example, a lithium ion secondary battery, but may be any other type of secondary battery, and the type is not particularly limited. This is the same for the second standby power supply device 320 as well. For example, the capacity of the battery unit 312 of the first standby power supply 310 is greater than the capacity of the battery unit 322 of the second standby power supply 320 . For example, the capacity of the battery unit 312 of the first standby power supply device 310 is a capacity that can maintain the cooling function of the refrigerator body 100 for several days after a power failure.

The first terminal portion 313 is provided at the first end portion 311 a of the first standby power supply case 311 . The first terminal portion 313 is a terminal portion for connecting the first standby power supply device 310 and the main body connector 330 . First standby power supply device 310 is electrically connected to refrigerator main body 100 via main body connector 330 , power supply circuit section 350 , and electrical connection member 403 by being connected to main body connector 330 . Thereby, the battery unit 312 of the first standby power supply device 310 can be charged with electric power supplied from the refrigerator main body 100 .

The second terminal portion 314 is provided at the second end portion 311 b of the first standby power supply case 311 . The second terminal portion 314 is a terminal portion for connecting the first standby power supply device 310 and the second standby power supply device 320 .

Voltage sensor VS1 detects the voltage value of the terminal voltage of battery unit 312 . Current sensor IS1 detects the current value of the current charged to or discharged from battery unit 312 . The detection results of the voltage sensor VS1 and the current sensor IS1 are output to the standby power supply general control section 360 via the first terminal section 313 and the main body connector 330, for example.

[4.2.3 Second Standby Power Supply]
Next, the configuration of the second standby power supply device 320 will be described.
The second standby power supply 320 is a standby power supply that can be separated from the refrigerator main body 100 as a portable power supply and carried to a desired location for use in the event of a power failure or a disaster that requires evacuation. That is, the second standby power supply device 320 can be used as a standby power supply device after being taken out of the case 210 of the disaster prevention unit 200 and carried to a living room, a bedroom, a shelter, or the like. The second standby power supply device 320 is used, for example, to charge various electronic devices (smartphones, tablet terminals, laptop computers, radios, portable televisions, etc.) owned by users.

However, some of these functional units may be provided as a part of the overall standby power supply control unit 360 or the second standby power supply control unit 328 instead of the refrigerator main body 100 .

Disaster detection unit 511 detects the occurrence of a disaster (for example, an earthquake) based on at least one of the disaster information received via network NW and the detection result of acceleration sensor AS. When disaster detection section 511 detects the occurrence of a disaster, disaster detection section 511 transmits a predetermined signal indicating the occurrence of a disaster to standby power supply general control section 360 and second standby power supply control section 328 . In addition, the disaster detection unit 511 detects that a disaster (for example, heavy rain) is imminent based on disaster information received via the network NW. The predetermined signal is transmitted to the standby power supply general control section 360 and the second standby power supply control section 328 . In the following, for convenience of explanation, "when a disaster actually occurs" and "when a disaster is about to occur (when there is a high possibility of a disaster occurring)" are collectively referred to as "occurrence of a disaster".

Cooling unit control section 512 controls driving of refrigerator compartment fan 143, freezer compartment fan 144, compressor 145, and the like. For example, when the disaster detection section 511 detects the occurrence of a disaster, the cooling unit control section 512 shifts to a low power mode for reducing the power consumption of the cooling unit 140 .

Charge/discharge control unit 513 maintains battery units 312 and 322 of standby power supply device 300 in a charged state using power supplied from commercial power source P to refrigerator main body 100 during normal times (non-disaster times). On the other hand, the charge/discharge control unit 513 discharges at least the battery unit 312 of the first standby power supply device 310 during a power failure, and drives the cooling unit 140 using the power obtained by discharging. At this time, the charging/discharging control unit 513 accepts a user's operation indicating an instruction to supply power also from the battery unit 322 of the second standby power supply device 320 to the refrigerator main body 100 through the operation unit 160 of the refrigerator main body 100 or the terminal device 2. If so, the battery unit 322 of the second standby power supply 320 is also discharged in addition to the battery unit 312 of the first standby power supply 310, and the cooling unit 140 is driven using the electric power obtained by discharging.

In addition, when the second standby power supply device 320 is used as a portable power supply and the remaining capacity is reduced and then the charge/discharge control unit 513 is electrically connected to the first standby power supply device 310, the charge/discharge control unit 513 The power discharged from the battery unit 312 may be used to charge the battery unit 322 of the second standby power supply device 320 .

Information acquisition unit 514 obtains information indicating the presence or absence of an abnormality in standby power supply device 300, the deterioration state of battery units 312 and 322 of standby power supply device 300, and the remaining capacity of battery units 312 and 322 of standby power supply device 300. Acquired from the overall control unit 360 . For example, the information acquisition unit 514 normally acquires the above information from the standby power supply overall control unit 360 at a predetermined cycle (for example, once a month). On the other hand, when the disaster detection unit 511 detects the occurrence of a disaster, the information acquisition unit 514 stores information indicating whether there is an abnormality in the standby power supply device 300 and the remaining capacity of the battery units 312 and 322 of the standby power supply device 300. Acquired from the power supply overall control unit 360 .

Based on the information acquired by the information acquisition unit 514, the information generation unit 515 generates the display screen D2 of the display device 150 of the refrigerator main body 100, the display screen D1 of the display device 2a of the terminal device 2, and the display device 325 of the standby power supply device 300. and the display area D3 of the front cover 220 of the disaster prevention unit 200 (hereinafter referred to as "display area D"). For example, the information generation unit 515 generates information indicating whether or not there is an abnormality in the standby power supply devices 310 and 320, information regarding the deterioration state of the battery units 312 and 322 of the standby power supply devices 310 and 320, At least one of the information about the remaining capacities of the units 312 and 322 is generated as information to be displayed in the display area D.

Here, the "information on the state of deterioration of the battery units 312, 322" is, for example, the reference timing for replacement of the battery units 312, 322 of the standby power supply devices 310, 320 and the necessity of replacement of the battery units 312, 322. Contains information indicating at least one. "Information about the remaining capacity of the battery units 312 and 322" is, for example, the operation continuable time of the refrigerator main body 100 (how long, operation can be continued) and information indicating the number of times the terminal device 2 or another terminal device can be charged with power supplied from the second standby power supply device 320. . In addition, the "information about the remaining capacity of the battery units 312 and 322" is the power supply of the refrigerator main body 100 when the refrigerator main body 100 is operated with the electric power supplied from both the first standby power supply device 310 and the second standby power supply device 320. It may also include information indicating the possible operation continuation time.

Normally, information generation unit 515 generates information indicating the presence or absence of an abnormality in standby power supply devices 310 and 320, the deterioration state of battery units 312 and 322 of standby power supply devices 310 and 320, , 320 is generated as information to be displayed in the display area D. On the other hand, when disaster detection unit 511 detects the occurrence of a disaster, information generation unit 515 determines whether or not there is an abnormality in standby power supply devices 310 and 320 and the remaining battery units 312 and 322 of standby power supply devices 310 and 320. Information indicating the capacity is generated as information to be displayed in the display area D. FIG.

When information to be displayed in display area D is generated by information generation unit 515 , display control unit 516 transmits the information to display device 150 of refrigerator main body 100 , display device 2 a of terminal device 2 , and second standby power supply device 320 . The information is transmitted to the display device 325 and the display device provided behind the front cover 220 of the disaster prevention unit 200, and the information is displayed in the display area D. FIG.

[5.2 Overall control unit for standby power supply of disaster prevention unit]
Next, the overall standby power supply controller 360 of the standby power supply device 300 will be described.
The standby power supply general control unit 360 has, for example, an abnormality detection unit 521, a deterioration detection unit 522, and a remaining capacity detection unit 523. However, some of these functional units may be provided as part of control unit 190 or second standby power supply control unit 328 of refrigerator main body 100 instead of standby power supply device 300 .

Abnormality detection unit 521 performs, for example, test discharge of battery units 312 and 322 of standby power supply devices 310 and 320, and based on the detection results of voltage sensors VS1 and VS2 and current sensors IS1 and IS2, Detect the presence or absence of anomalies. The detection result of abnormality detection unit 521 is transmitted to control unit 190 and second standby power supply control unit 328 of refrigerator main body 100 .

Degradation detection unit 522 detects battery units 312 and 322 based on the detection results of voltage sensors VS1 and VS2 and current sensors IS1 and IS2 when test discharge of battery units 312 and 322 of standby power supply devices 310 and 320 is performed. Detect degraded conditions. Here, in the storage unit 370 of the standby power supply device 300, information indicating the deterioration characteristics of the battery units 312 and 322 (for example, the relationship between the combination of the integrated value of the discharge amount and the voltage drop amount of the terminal voltage and the degree of deterioration). is stored. Degradation detection unit 522 detects the integrated value of the amount of discharge from battery units 312 and 322 detected in the test discharge, the voltage drop amount of the terminal voltage of battery units 312 and 322, and the deterioration characteristics stored in storage unit 370. and based on the information indicating the deterioration state of the battery units 312 and 322 is detected. However, the deterioration state detection method is not limited to the above example, and various known methods can be used. The detection result of deterioration detection unit 522 is transmitted to control unit 190 and second standby power supply control unit 328 of refrigerator main body 100 .

The remaining capacity detection unit 523 detects the remaining capacity of the battery units 312 and 322 based on the terminal voltage detection results of the battery units 312 and 322 of the standby power supply devices 310 and 320 detected by the voltage sensors VS1 and VS2. However, the method of detecting the remaining capacity is not limited to the above example, and various known methods can be used. The detection result of remaining capacity detection unit 523 is transmitted to control unit 190 and second standby power supply control unit 328 of refrigerator main body 100 .

The abnormality detection unit 521, the deterioration detection unit 522, and the remaining capacity detection unit 523 normally perform test discharge of the battery units 312 and 322 at the above-described predetermined cycle, and detect the presence or absence of abnormality and deterioration state of the battery units 312 and 322. , the remaining capacity of the battery units 312 and 322 is detected. On the other hand, when abnormality detection unit 521 and remaining capacity detection unit 523 receive a predetermined signal indicating the occurrence of a disaster from disaster detection unit 511 of refrigerator main body 100, for example, change in terminal voltage of battery units 312 and 322 Detects the presence or absence of abnormality in the battery units 312, 322 and the remaining capacity of the battery units 312, 322 based on the presence or absence of the battery unit 312, 322, and transmits the detection results to the control unit 190 of the refrigerator main body 100 and the second standby power supply control unit 328. . For example, when the abnormality detection unit 521 receives a predetermined signal indicating the occurrence of an earthquake from the disaster detection unit 511 of the refrigerator main body 100, after the earthquake occurs (after the detection result of the acceleration sensor AS falls within the threshold value), the battery The presence or absence of abnormality in units 312 and 322 is detected, and the detection results are transmitted to control section 190 and second standby power supply control section 328 of refrigerator main body 100 .

[5.3 Second Standby Power Supply Control Section of Disaster Prevention Unit]
Next, the second standby power supply control section 328 of the disaster prevention unit 200 will be described.
The second standby power supply control unit 328 has, for example, a discharge control unit 531, a remaining capacity detection unit 532, an information generation unit 533, and a display control unit 534. However, some of these functional units may be provided as part of the control unit 190 of the refrigerator body 100 or the overall standby power supply control unit 360 instead of the second standby power supply device 320 .

The discharge control unit 531 discharges the battery unit 322 of the second standby power supply 320 when the second standby power supply 320 is used as a portable power supply and the connector 326 is connected to a device to which power is to be supplied. The power obtained from this is supplied to the device.

For example, when the second standby power supply 320 is used as a portable power supply, the remaining capacity detection unit 532 detects the terminal voltage of the battery unit 322 of the second standby power supply 320 detected by the voltage sensor VS2. The remaining capacity of the battery unit 322 is detected. However, the method of detecting the remaining capacity is not limited to the above example, and various known methods can be used.

For example, when the second standby power supply device 320 is used as a portable power supply, the information generation unit 533 generates information to be displayed on the display screen D4 of the second standby power supply device 320 based on the detection result of the remaining capacity detection unit 532. Generate.

When information to be displayed on the display screen D4 is generated by the information generation unit 533, the display control unit 534 transmits the information to the display device 325 and displays the information on the display screen D4. Display control unit 534 receives information to be displayed on display screen D4 from control unit 190 of refrigerator body 100 or standby power supply general control unit 360, transmits the information to display device 325, and displays the information on display screen D4. to display.

According to the above configuration, it is possible to improve user convenience. That is, in this embodiment, the case 210 of the disaster prevention unit 200 is arranged above the refrigerator main body 100, and the standby power supply device 300 is housed inside the case 210. As shown in FIG. According to such a configuration, the space above the refrigerator body 100, which tends to become a dead space, can be used to secure electricity in the event of a disaster.

In this embodiment, the standby power supply device 300 has a first standby power supply device 310 that supplies power to the refrigerator main body 100 during a power failure. With such a configuration, even if a power failure occurs, the operation of the refrigerator body 100 can be continued, making it easier to secure food for several days until restoration progresses. In addition, in this embodiment, the standby power supply device 300 includes a second standby power supply device 320 that can be used as a portable power supply. With such a configuration, the second standby power supply device 320 can be used at a desired place in the home, at a shelter, or the like.

In this embodiment, the second standby power supply device 320 is connected to the first standby power supply device 310 so that power is supplied from the refrigerator main body 100 via the first standby power supply device 310 to charge the second standby power supply device 320 . According to such a configuration, it becomes easier to arrange the second standby power supply 320 in front of the first standby power supply 310 compared to the case where the body connector 330 is provided with an electrical connection portion for the second standby power supply 320 . . Arranging the second standby power supply 320 in front of the first standby power supply 310 makes it easier to remove the second standby power supply 320 .

In this embodiment, the first standby power supply device 310 is heavier than the second standby power supply device 320 and is arranged behind the second standby power supply device 320 or below the second standby power supply device 320 . According to such a configuration, the center of gravity of the disaster prevention unit 200 tends to be located rearward or downward, and the refrigerator 1 equipped with the disaster prevention unit 200 can be easily stabilized.

Next, several modifications of the first embodiment will be described. In addition, in each modified example, the configuration other than that described below is the same as the configuration of the first embodiment.

(First modification)
FIG. 15 is a side view showing a partial cross section of the refrigerator 1 of the first modified example. Here, the refrigerator 1 is often arranged along the wall W of the house. A machine room at the bottom of refrigerator main body 100 is provided with a fan (not shown) for accelerating heat radiation from compressor 145 . The air blown by this fan rises through the gap between the rear wall 115 and the wall W of the refrigerator body 100 due to the chimney effect. That is, the air blown by the fan rises along the rear wall 115 of the refrigerator body 100 .

FIG. 16 is a cross-sectional view showing the disaster prevention unit 200 of this modified example. In this modified example, a plurality of air intake holes 411 are provided in the rear wall 215 of the case 210 . On the other hand, a plurality of exhaust holes 412 are provided in left and right side walls 213 and 214 of case 210 .

In this modification, the disaster prevention unit 200 is provided, for example, on the rear wall 215 of the case 210 and guides at least part of the air rising along the rear wall 115 of the refrigerator body 100 toward the air intake hole 411 of the case 210. It has a guide member 601 . The guide member 601 is provided slightly above the intake hole 411, for example. Guide member 601 protrudes rearward from case 210 and is positioned above the gap between rear wall 115 and wall W of refrigerator body 100 . The air rising along the rear wall 115 of the refrigerator main body 100 collides with the guide member 601 and is guided to the air intake hole 411 by changing the direction of flow, and is led from the air intake hole 411 to the standby power supply compartment PS. In this modification, the fan 340 may be provided or omitted.

According to such a configuration, by providing the guide member 601 , at least part of the air that has risen along the rear wall 115 of the refrigerator body 100 due to the chimney effect can be efficiently taken into the case 210 . . Thereby, the heat dissipation of the standby power supply device 300 can be improved.

In addition, when the fan 340 is provided in this modification, the air in the gap between the rear wall 115 and the wall W of the refrigerator main body 100 is removed by driving the fan 340 and taking in air from the air intake hole 411 . 210 can be actively guided inside. If the air in the gap between the rear wall 115 of the refrigerator main body 100 and the wall W can be positively led into the case 210, the air in the gap between the rear wall 115 of the refrigerator main body 100 and the wall W can be introduced. It becomes difficult to stay, and the heat radiation of the heat radiation pipe 146 provided in the rear wall 115 of the refrigerator main body 100 can be promoted. Thereby, the heat dissipation of the refrigerator main body 100 can be improved.

(Second modification)
FIG. 17 is a cross-sectional view showing a disaster prevention unit 200 of a second modified example. In this modification, the outer surface of the rear wall 115 of the case 210 of the disaster prevention unit 200 is embossed. That is, the outer surface of rear wall 115 of case 210 has a plurality of recesses 605 and a plurality of protrusions 606 . The concave portions 605 and the convex portions 606 are alternately arranged in the vertical direction.

According to such a configuration, part of the air rising along the rear wall 115 of the refrigerator body 100 tends to be in a turbulent state, and the gap between the rear wall 215 of the case 210 of the disaster prevention unit 200 and the wall W. Air can pass through smoothly and easily escape upward. As a result, the circulation of the air around the refrigerator 1 can be enhanced, and the heat dissipation of the refrigerator 1 can be improved.

(Third modification)
FIG. 18 is a cross-sectional view showing the refrigerator 1 of the third modified example. In this modification, the ceiling wall 111 of the refrigerator body 100 has a first region R1 and a second region R2. The first region R1 is located below the standby power supply device 300 (below the standby power supply compartment PS). The second region R2 is located outside the first region R1. That is, the second region R2 does not overlap the standby power supply device 300 in the vertical direction.

In this modification, the thickness T1 of the heat insulating material 110c in at least a portion of the first region R1 of the ceiling wall 111 is thinner than the thickness T2 of the heat insulating material 110c in the second region R2 of the ceiling wall 111. For example, the heat insulating material 110c is thin in the region between the pair of legs 280 of the disaster prevention unit 200 in the first region R1. Further, in this modification, the vacuum heat insulating material 111a is not provided at least in the region where the heat insulating material 110c is thin.

According to such a configuration, the upper surface of ceiling wall 111 of refrigerator main body 100 is easily cooled by cold air from storage room 120, and the temperature of the upper surface of ceiling wall 111 is less likely to rise. Therefore, the temperature of the air in the gap S2 between the ceiling wall 111 of the refrigerator body 100 and the disaster prevention unit 200 is less likely to rise. As a result, it is possible to improve the heat dissipation of the standby power supply device 300 .

(Fourth modification)
FIG. 19 is a cross-sectional view showing refrigerator 1 of a fourth modification. In this modification, the thickness T1 of the heat insulating material 110c in at least a part of the first region R1 of the ceiling wall 111 (when the heat insulating material 110c exists so as to sandwich the vacuum heat insulating material 111a from above and below, the thickness of the vacuum heat insulating material 111a is The sum of the thickness t1 of the upper heat insulating material 110c and the thickness t2 of the lower heat insulating material 110c of the vacuum heat insulating material 111a) is thicker than the thickness T2 of the heat insulating material 110c in the second region R2 of the ceiling wall 111. For example, the heat insulating material 110c is thicker in a region larger than the region between the pair of legs 280 of the disaster prevention unit 200 in the width direction of the refrigerator 1 .

According to such a configuration, when the standby power supply device 300 generates heat, the heat of the standby power supply device 300 is suppressed from being transmitted to the inside of the storage chamber 120 . Thereby, the temperature rise in the storage chamber 120 can be suppressed.

(Fifth modification)
FIG. 20 is a cross-sectional view showing refrigerator 1 of the fifth modification. In this modification, the bottom wall 212 of the case 210 of the disaster prevention unit 200 has heat insulation. In other words, case 210 has an adiabatic wall (bottom wall 212 ) between standby power supply compartment PS and refrigerator main body 100 . The bottom wall 212 has, for example, a first portion 212a made of synthetic resin and a second portion 212b made of a heat-insulating member. overlapping. The second portion 212b is made of, for example, a vacuum heat insulating material. In addition, the second portion 212b may be formed of a foam heat insulating material such as urethane foam.

According to such a configuration, when the standby power supply device 300 generates heat, the heat of the standby power supply device 300 is suppressed from being transmitted to the inside of the storage chamber 120 . Thereby, the temperature rise in the storage chamber 120 can be suppressed.

(Sixth modification)
FIG. 21 is a cross-sectional view showing refrigerator 1 of the sixth modification. In this modification, the bottom wall 212 of the case 210 of the disaster prevention unit 200 has a pair of inclined surfaces 611,612. Each of the inclined surfaces 611 and 612 is located upward as it progresses toward the outer peripheral side of the case 210 . In this modification, the bottom wall 212 of the case 210 includes a flat surface 613 located in the center of the bottom wall 212, a left inclined surface 611 adjacent to the left side of the flat surface 613, and a right inclined surface 612 adjacent to the right side of the flat surface 613. have. For example, the sum of the width W1 of the left slanted surface 611 and the width W2 of the right slanted surface 612 is substantially equal to or larger than the width W3 of the plane 613 .

According to such a configuration, the air in the gap S2 between the case 210 of the disaster prevention unit 200 and the ceiling wall 111 of the refrigerator body 100 can easily escape to the outer peripheral side (left or right side) of the case 210 . As a result, air is less likely to stay in the gap S2, and relatively cold air is more likely to flow into the gap S2. As a result, it is possible to improve the heat radiation performance of the standby power supply device 300 and suppress the temperature rise in the storage chamber 120 .

(Second embodiment)
Next, the refrigerator 1 of 2nd Embodiment is demonstrated. This embodiment differs from the first embodiment in that the disaster prevention unit 200 has disaster prevention supply chambers GS1, GS2, and GS3 capable of containing disaster prevention supplies 700. FIG. Configurations other than those described below are the same as those of the first embodiment.

FIG. 22 is a front view showing the refrigerator 1 of the second embodiment. In this embodiment, the disaster prevention unit 200 has a larger case 210 than in the first embodiment. The center of case 210 in the width direction substantially coincides with the center of refrigerator body 100 in the width direction. For example, case 210 has four storage chambers.

FIG. 23 is a cross-sectional view showing the disaster prevention unit 200 of this embodiment. In this embodiment, the case 210 has first to third disaster prevention product storage chambers (disaster prevention product storage spaces) GS1, GS2, and GS3 in addition to the standby power supply storage chamber PS in which the standby power supply device 300 is stored. A partition wall 217 provided inside the case 210 separates the four storage rooms including the emergency supply storage rooms GS1, GS2, GS3 and the standby power supply storage room PS from each other. For example, the partition wall 217 is made of synthetic resin and has electrical insulation. As a result, even if the standby power supply device 300 should be damaged by an earthquake, for example, the electrical safety inside the emergency supply storage rooms GS1, GS2, and GS3 is ensured more reliably.

FIG. 24 is a cross-sectional view along line F24-F24 of the disaster prevention unit 200 shown in FIG. FIG. 25 is a cross-sectional view along line F25-F25 of the disaster prevention unit 200 shown in FIG. For example, the first to third emergency supply storage chambers GS1, GS2, and GS3 have approximately the same depth as the standby power source storage chamber PS in the front-rear direction of the refrigerator body 100. As shown in FIG.

Disaster prevention goods (disaster prevention goods) 700 are stored in each of the disaster prevention goods storage chambers GS1, GS2, and GS3. The disaster supplies 700 include, for example, plastic bottles of drinking water, foods that can be stored for a long period of time (dry bread, canned foods, retort foods, instant foods, candies, chocolates, etc.), polyethylene tanks for water supply, cassette stoves and cylinders, portable radios, helmets, and disaster prevention. Hoods, thick gloves, flashlights, utility knives, masks, tissue paper, wet wipes, portable toilets, first aid kits, medicines, portable warmers, lighters/matches, candles, etc., but not limited to these. Some or all of these items are stored in disaster prevention item storage rooms GS1, GS2, and GS3 in a state of being put in an emergency bag.

Next, referring back to FIG. 23, the positional relationship between the three disaster prevention goods storage rooms GS1, GS2, and GS3 and the standby power supply storage room PS will be described. In this embodiment, the first and second disaster prevention goods storage chambers GS1 and GS2 are arranged to the left of the standby power supply storage chamber PS. The first disaster prevention goods storage room GS1 and the standby power supply storage room PS are arranged at substantially the same height position. The second disaster prevention goods storage room GS2 is arranged above the first disaster prevention goods storage room GS1, and is arranged at a position higher than the standby power supply storage room PS. The third emergency goods storage room GS3 is arranged above the standby power supply storage room PS. The second disaster prevention goods storage room GS2 and the third disaster prevention goods storage room GS3 are arranged at the same height.

In other words, the standby power storage room PS is located at the lowest position among the four storage rooms including the first to third emergency supply storage rooms GS1, GS2, GS3 and the standby power supply storage room PS. do. Here, the weight of the standby power supply device 300 is heavier than the weight of the emergency supplies 700 . For this reason, if the standby power supply housing room PS is provided in the lower part, the center of gravity of the disaster prevention unit 200 will be lowered, and the disaster prevention unit 200 will be easier to stabilize.

Looking at the above arrangement from a different point of view, the standby power supply compartment PS is located on the right side of the center of the width direction of the case 210 (left and right refrigerator compartment doors 131A of the center of the width direction of the refrigerator main body 100). , 131B are biased toward the side opposite to the biased side). As a result, the impact applied to disaster prevention unit 200 when refrigerator doors 131A and 131B are closed is less likely to be transmitted to standby power supply device 300 . In this embodiment, the entire standby power supply compartment PS is positioned so as not to overlap the boundary between the left and right refrigerator compartment doors 131A and 131B in the front-rear direction of the refrigerator 1. are shifted to the right.

According to such a configuration, the space above refrigerator body 100, which tends to become dead space, can be used to secure electricity and food in the event of a disaster. It should be noted that it is not necessary to provide three emergency supply storage rooms, but one, two, or four or more may be provided.

(Third embodiment)
Next, the refrigerator 1 of 3rd Embodiment is demonstrated. This embodiment differs from the second embodiment in that the disaster prevention unit 200 has a lighting device housing chamber LS that can house the lighting device 800 .
