The refrigerator 1 can receive disaster information transmitted from the server apparatus 3 via the network NW.

[2. integral constitution of refrigerator ]

Fig. 2 is a front view showing the refrigerator 1 of the present embodiment. The refrigerator 1 includes, for example, a refrigerator main body 100 and a disaster prevention unit 200. The disaster prevention unit 200 is an example of a "refrigerator-attached disaster prevention unit".

[3. constitution of refrigerator Main body ]

First, the structure of the refrigerator main body 100 will be described.

The refrigerator main body 100 includes, for example, a heat insulating housing 110 (see fig. 3), a plurality of doors 130, a cooling unit 140 (see fig. 3), a display device 150, an operation unit 160, a wireless communication unit 170, a power supply circuit unit 180, an acceleration sensor AS, and a control unit 190.

Fig. 3 is a sectional view of the refrigerator 1 shown in fig. 2 taken along the line F3-F3. The heat insulating frame 110 has, for example, an outer box 110a, an inner box 110b, and a heat insulating material 110c filled between the outer box 110a and the inner box 110b, and has heat insulation properties. The heat insulator 110c is a foamed heat insulator such as foamed urethane.

The heat insulating frame 110 has a top wall 111, a bottom wall 112, left and right side walls 113 and 114 (see fig. 4), and a rear wall 115. The left and right side walls 113 and 114 rise upward from the left and right end portions of the bottom wall 112 and are connected to the left and right end portions of the top wall 111. The rear wall 115 rises upward from the rear end of the bottom wall 112 and is connected to the rear end of the top wall 111.

A plurality of storage chambers 120 are provided inside the heat insulating frame 110. The plurality of storage compartments 120 include, for example, a refrigerating compartment 121, a vegetable compartment 122, an ice making compartment 123 (see fig. 2), a small freezing compartment 124, and a main freezing compartment 125. In the present embodiment, refrigerating room 121 is disposed at the uppermost portion, vegetable room 122 is disposed below refrigerating room 121, ice making room 123 and small freezing room 124 are disposed below vegetable room 122, and main freezing room 125 is disposed below ice making room 123 and small freezing room 124. However, the arrangement of storage room 120 is not limited to the above example, and the positions of vegetable room 122 and main freezer 125 may be changed, for example. The heat insulating frame 110 has an opening O on the front surface side of each storage chamber 120, through which food can be taken in and out of each storage chamber 120.

The opening O of the storage chamber 120 is openably and closably closed by a plurality of doors 130. The plurality of cells 130 include, for example, refrigerating compartment doors 131A, 131B (refer to fig. 2) closing the opening O of the refrigerating compartment 121, a vegetable compartment door 132 closing the opening O of the vegetable compartment 122, an ice making compartment door 133 (refer to fig. 2) closing the opening O of the ice making compartment 123, a small freezing compartment door 134 closing the opening O of the small freezing compartment 124, and a main freezing compartment door 135 closing the opening O of the main freezing compartment 125. The left and right refrigerating compartment doors 131A, 131B are, for example, split doors. In the present embodiment, the width WB of the right refrigerating compartment door 131B in the lateral width direction is larger than the width WA of the left refrigerating compartment door 131A in the lateral width direction (see fig. 2). That is, the boundary between the left and right refrigerating compartment doors 131A and 131B is located on the left side with respect to the center in the lateral width direction of the refrigerator main body 100 (the center in the lateral width direction of the heat insulating frame 110). The vegetable compartment door 132, the ice making compartment door 133, the mini-freezer compartment door 134, and the main-freezer compartment door 135 are, for example, drawer-type doors.

Here, an example of the top wall 111 will be described in detail.

Fig. 4 is a cross-sectional view of the insulated frame 110 shown in fig. 3 taken along line F4-F4. The top wall 111 includes, for example, a Vacuum Insulation Panel (VIP) 111 a. The vacuum heat insulator 111a is formed in a plate shape substantially parallel to the upper surface (or lower surface) of the ceiling wall 111, and is disposed between the inner box 110b and the heat insulator 110 c. When the vacuum heat insulating material 111a is provided, when the auxiliary power supply device 300 of the disaster prevention unit 200 described later generates heat, the heat of the auxiliary power supply device 300 can be suppressed from being transmitted to the inside of the storage room 120.

The top wall 111 may also have a reinforcing member 111 b. The reinforcing member 111b is, for example, a member having higher rigidity than one or more of the outer box 110A, the inner box 110b, and the heat insulating material 110c, and is, for example, a metal member. The reinforcing member 111b is provided substantially parallel to the upper surface (or lower surface) of the top wall 111, for example, and is disposed between the outer box 110a and the heat insulator 110 c. The reinforcing member 111b extends over at least a part of the left sidewall 113 and over at least a part of the right sidewall 114. When the reinforcing member 111b is provided, the load of the disaster prevention unit 200 is easily supported by the left side wall 113 and the right side wall 114. However, the reinforcing member 111b is not an essential component, and may be absent when sufficient rigidity is secured.

A terminal portion 117 is provided on the top wall 111, and an electrical connection member 403 (see fig. 5) of the disaster prevention unit 200 described later is detachably connected to the terminal portion 117. The terminal unit 117 includes, for example, a power terminal PT through which a current for supplying power flows and a signal terminal ST through which a signal flows, and can transmit and receive power and a signal. Terminal portions 313, 314, 316, 323, 331, and 803 of the disaster prevention unit 200 described below also have a power terminal PT and a signal terminal ST, respectively, in the same manner as the terminal portion 117, and can transmit and receive power and signals.

Next, returning to fig. 3, the cooling unit 140 will be described. The cooling unit 140 includes, for example, a plurality of coolers 141 and 142, a plurality of fans 143 and 144, a compressor 145, and a heat radiation pipe 146 (see fig. 5).

The plurality of coolers 141 and 142 include, for example, a refrigerator compartment cooler 141 provided behind refrigerator compartment 121 or vegetable compartment 122, and a freezer compartment cooler 142 provided behind main freezer compartment 125 or small freezer compartment 124. The plurality of fans 143 include a refrigerating room fan 143 that circulates air (cold air) cooled by refrigerating room cooler 141 in refrigerating room 121 and vegetable room 122, and a freezing room fan 144 that circulates air (cold air) cooled by freezing room cooler 142 in refrigerating room 123, small freezing room 124, and main freezing room 125.

The compressor 145 is provided in, for example, a machine room in the bottom of the refrigerator 1. The compressor 145 compresses a refrigerant gas used for cooling the storage chamber 120. The refrigerant gas compressed by the compressor 145 is sent to the refrigerating compartment cooler 141 and the freezing compartment cooler 142 through the heat pipe 146 and the like.

Fig. 5 is a plan view showing the refrigerator main body 100. In fig. 5, the guide member 420 and the like, which will be described later, are not illustrated. The heat radiating pipe 146 releases heat of the refrigerant flowing in the heat radiating pipe 146, so that the temperature of the refrigerant is lowered. The heat pipe 146 is disposed on the left and right side walls 113 and 114 and the rear wall 115 of the heat insulating frame 110. A part of the heat pipe 146 is provided in the top wall 111, for example, in a substantially central portion of the top wall 111. Therefore, a portion of the top wall 111 may receive heat from the radiating pipe 146 and rise in temperature.

Next, returning to fig. 2, another configuration of the refrigerator main body 100 will be described.

The display device 150 is disposed, for example, in front of the refrigerating chamber door 131B. The display device 150 is a liquid crystal display, an organic EL display, or the like, and has a display screen (display area) D2 on which images and/or characters can be displayed.

The operation unit 160 is, for example, a touch panel type input device, and is provided so as to overlap the display screen D2 of the display device 150. The user can perform predetermined input and/or selection to the refrigerator main body 100 by operating the operation unit 160. The operation unit 160 is not limited to a touch panel type input device, and may be a button or the like provided in the refrigerator main body 100.

The wireless communication unit 170 includes a high-frequency circuit, an antenna, and the like, and can be connected to the network NW by wireless. For example, the wireless communication unit 170 is connected to the network NW via an access point provided in a home in which the refrigerator 1 is installed.

The power circuit unit 180 is implemented by, for example, one or more power circuit boards, and is disposed at an upper end portion of the refrigerator main body 100. The power supply circuit unit 180 is electrically connected to the commercial power supply P via a power supply cable 185 of the refrigerator main body 100, a household outlet, and the like. In a normal state (non-disaster state), the power supply circuit unit 180 is supplied with ac power from the commercial power supply P. The commercial power supply P is an example of an "external power supply".

Fig. 6 is a block diagram showing a connection relationship of power lines of the refrigerator 1. The power supply circuit unit 180 converts ac power supplied from the commercial power supply P into dc power having a voltage suitable for each device included in the refrigerator 1, and supplies the converted dc power to the devices. For example, the power supply circuit unit 180 supplies the dc power obtained by the conversion to the cooling unit 140, the display device 150, the operation unit 160, and the like.

The acceleration sensor AS is provided in the heat insulating frame 110 or the door 130. The acceleration sensor AS detects a large acceleration when an earthquake occurs. The detection result of the acceleration sensor AS is output to the control unit 190. The acceleration sensor AS is an example of a "sensor".

The control unit 190 is implemented by, for example, one or more control boards, and is disposed at the upper end of the refrigerator main body 100. The power supply circuit unit 180 and the control unit 190 may be realized by one substrate. The control unit 190 controls the entire refrigerator 1. For example, the control unit 190 collectively controls the operations of the cooling unit 140, the display device 150, the operation unit 160, the wireless communication unit 170, the power supply circuit unit 180, and the disaster prevention unit 200. The function of the control unit 190 will be described in detail later.

[4. construction of disaster prevention Unit ]

Next, the configuration of the disaster prevention unit 200 will be explained.

Fig. 7 is a sectional view of the disaster prevention unit 200 shown in fig. 3 taken along line F7-F7. The disaster prevention unit 200 includes, for example, a case 210, a front cover 220 (see fig. 10), a backup power supply device 300, a buffer member 240, a support surface forming member 250, a leakage receiving portion 260, a backup power supply fixing portion 270, a pair of leg portions 280, and a case fixing portion 290.

[4.1 casing and front cover ]

First, the case 210 will be explained.

The case 210 is disposed above the refrigerator main body 100 and fixed to the refrigerator main body 100 by a case fixing portion 290 to be described later. The housing 210 has, for example, an upper wall 211, a bottom wall 212, left and right side walls 213 and 214, and a rear wall 215. The upper wall 211 and the bottom wall 212 extend substantially parallel to the top wall 111 of the refrigerator main body 100. The left and right side walls 213, 214 rise upward from the left and right end portions of the bottom wall 212 and are connected to the left and right end portions of the upper wall 211. Rear wall 215 rises upward from the rear end of bottom wall 212 and is continuous with the rear end of upper wall 211. The housing 210 is formed in a box shape having an opening 210a on the front surface side. The widthwise center of the case 210 substantially coincides with the widthwise center of the refrigerator main body 100. The case 210 is made of, for example, synthetic resin and has electrical insulation. A housing chamber (housing space) for housing devices and/or supplies, etc., which are useful when a disaster occurs, is formed inside the case 210.

In the present embodiment, a preliminary power supply housing chamber (preliminary power supply housing space) PS for housing the preliminary power supply device 300 is formed inside the casing 210. For example, the housing 210 has a pair of support portions 401 that support the left and right end portions of the auxiliary power supply device 300 accommodated in the auxiliary power supply accommodation chamber PS from below. The pair of support portions 401 extends in the depth direction of the refrigerator 1. The pair of support portions 401 are separated from each other in the lateral width direction of the refrigerator 1. A space is provided between the pair of support portions 401. Thus, a gap S1 that allows expansion of the auxiliary power supply 300 during aging (expansion of the battery cells 312 and 322 described later) is formed between the auxiliary power supply 300 and the bottom wall 212 of the case 210.

The front cover 220 is positioned in front of the opening 210a of the case 210. The front cover 220 is pivotally supported by a hinge, not shown, for example, and closes the opening 210a of the housing 210 in an openable and closable manner. The front cover 220 is formed of a material similar to the door 130 of the refrigerator main body 100. For example, in the case where the door 130 of the refrigerator main body 100 has a glass plate, the front cover 220 is formed of a glass plate, and in the case where the door 130 of the refrigerator main body 100 has a metal plate, the front cover 220 is formed of a metal plate. This can improve the sense of unity between the disaster prevention unit 200 and the refrigerator main body 100.

Further, the front cover 220 may be formed of a transparent member. In this case, the display screen D4 of the auxiliary power supply device 300, which will be described later, can be visually recognized from the outside through the front cover 220. Further, at least a part of the front cover 220 may be formed of a transparent or translucent member, and the display region D3 may be formed by a display device provided behind the front cover 220 (see fig. 2). In this case, characters and/or graphics projected from a display device provided behind the front cover 220 toward the front cover 220 are displayed in the display area D3.

[4.2 Standby Power supply device ]

[4.2.1 Overall configuration of Standby Power supply device ]

Next, the auxiliary power supply device 300 will be explained.

The auxiliary power supply 300 supplies electric power instead of the commercial power supply P at the time of power failure (disaster occurrence). The auxiliary power supply device 300 is electrically connected to the refrigerator main body 100 via an electrical connection member 403 such as a cable or a bus bar. Thus, the auxiliary power supply device 300 can be electrically connected to the commercial power supply P via the electric connection member 403, the power line 404 (see fig. 6) in the refrigerator main body 100, the power cable 185 of the refrigerator main body 100, and the like.

The auxiliary power supply device 300 can be charged with a part of the electric power supplied from the commercial power supply P to the refrigerator main body 100 at the normal time. "electric power supplied from commercial power supply P to refrigerator main body 100" broadly means electric power introduced from commercial power supply P into refrigerator main body 100 via power supply cable 185 of refrigerator main body 100, for example. "capable of being charged using a part of the electric power supplied from the commercial power supply P to the refrigerator main body 100" includes any of the following cases: a case where the electric power supplied from the commercial power supply P to the refrigerator main body 100 is supplied to the auxiliary power supply device 300 without any conversion in the refrigerator main body 100 (for example, supplied with the ac power being maintained) and thereby the auxiliary power supply device 300 can be charged; and the power supplied from commercial power supply P to refrigerator main body 100 is converted into desired power (for example, dc power) in refrigerator main body 100 and supplied to auxiliary power supply device 300, whereby auxiliary power supply device 300 can be charged. In other words, the auxiliary power supply device 300 may be electrically connected to the commercial power supply P without passing through the power supply circuit portion 180 of the refrigerator main body 100, or may be electrically connected to the commercial power supply P through the power supply circuit portion 180 of the refrigerator main body 100.

In the present specification, "being chargeable by being supplied with electric power from the commercial power supply P via the refrigerator main body 100" and "being chargeable by being supplied with electric power from the refrigerator main body 100" are used in the same sense as "being chargeable by using a part of electric power supplied from the commercial power supply P to the refrigerator main body 100" described above. That is, these representations can be interchanged.

In the present embodiment, at least a part of the auxiliary power supply device 300 can be used separately from the refrigerator main body 100 as a portable power supply. In the present specification, "usable and separable from the refrigerator main body 100" and "separable from the refrigerator main body 100" mean that the refrigerator main body 100 can be transported to a place different from the place where the refrigerator main body 100 is installed and used. Further, "portable power source" broadly means a portable power source, and includes a relatively small-sized mobile battery and the like.

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

Fig. 8 is a perspective view showing the auxiliary power supply main body 300U. In the present embodiment, the auxiliary power supply main body 300U includes a1 st auxiliary power supply 310 and a2 nd auxiliary power supply 320.

[4.2.2 No. 1 Standby Power supply device ]

First, the configuration of the 1 st auxiliary power supply device 310 will be described.

The 1 st auxiliary power supply device 310 is an auxiliary power supply device that supplies power to the refrigerator main body 100 when a power failure occurs. That is, the 1 st auxiliary power supply device 310 is retained integrally with the refrigerator main body 100 (retained inside the case 210 of the disaster prevention unit 200) at the time of power failure, and supplies power necessary for maintaining the cooling function of the refrigerator 1, such as power for driving the compressor 145 and the cooling unit 140, to the refrigerator main body 100.

Specifically, the 1 st auxiliary power supply device 310 includes, for example, a1 st auxiliary power supply case 311, a battery cell 312, a1 st terminal unit 313, a2 nd terminal unit 314, a voltage sensor VS1 (see fig. 6), and a current sensor IS1 (see fig. 6).

The 1 st auxiliary power supply case 311 is formed in a box shape, for example. The 1 st preliminary power supply case 311 has a1 st end 311a and a2 nd end 311 b. The 1 st end 311a is an end facing a main body connector 330 described later. The 2 nd end 311b is located opposite to the 1 st end 311a, and faces the 2 nd auxiliary power supply unit 320.

The battery unit 312 is housed inside the 1 st auxiliary power supply case 311. The battery unit 312 includes one or more secondary batteries. The secondary battery is, for example, a lithium ion secondary battery, but may be another type of secondary battery, and the type thereof is not particularly limited. The same applies to the 2 nd auxiliary power supply unit 320. For example, the capacity of the battery cell 312 of the 1 st auxiliary power supply device 310 is larger than the capacity of the battery cell 322 of the 2 nd auxiliary power supply device 320. For example, the capacity of the battery unit 312 of the 1 st auxiliary power supply device 310 is a capacity capable of maintaining the cooling function of the refrigerator main body 100 for several days after the power failure.

The 1 st terminal portion 313 is provided at the 1 st end portion 311a of the 1 st preliminary power supply case 311. The 1 st terminal portion 313 is a terminal portion for connecting the 1 st auxiliary power supply device 310 and the main body connector 330. The 1 st auxiliary power supply device 310 is connected to the main body connector 330, and is electrically connected to the refrigerator main body 100 via the main body connector 330, the power supply circuit portion 350, and the electrical connection member 403. Thereby, the battery unit 312 of the 1 st auxiliary power supply device 310 is supplied with power from the refrigerator main body 100 and can be charged.

The 2 nd terminal portion 314 is provided at the 2 nd end portion 311b of the 1 st auxiliary power supply case 311. The 2 nd terminal unit 314 is a terminal unit for connecting the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320.

The voltage sensor VS1 detects the voltage value of the terminal voltage of the battery cell 312. The current sensor IS1 detects the current value of the current that IS charged to the battery cell 312 or discharged from the battery cell 312. The detection results of the voltage sensor VS1 and the current sensor IS1 are output to the auxiliary power supply overall control unit 360 via, for example, the 1 st terminal unit 313 and the main body connector 330.

[4.2.3 No. 2 Standby Power supply device ]

Next, the configuration of the 2 nd auxiliary power supply device 320 will be described.

The 2 nd auxiliary power supply device 320 is an auxiliary power supply device that can be separated from the refrigerator main body 100 as a portable power supply and transported to a desired place for use in the event of a power failure or disaster requiring evacuation. That is, the 2 nd auxiliary power supply device 320 can be taken out of the housing 210 of the disaster prevention unit 200 and used as an auxiliary power supply device in a state of being transported to a living room, a bedroom, an evacuation, or the like. The 2 nd auxiliary power supply device 320 is used for charging various electronic devices (a smartphone, a tablet terminal, a notebook computer, a radio, a portable television, and the like) held by a user, for example.

The 2 nd auxiliary power supply device 320 is capable of supplying power to the refrigerator main body 100 together with the 1 st auxiliary power supply device 310 without being separated from the refrigerator main body 100. That is, for example, when the sustainable operation time of the refrigerator main body 100 at the time of power failure is to be increased, the 2 nd auxiliary power supply device 320 is retained integrally with the refrigerator main body 100 together with the 1 st auxiliary power supply device 310 (retained inside the case 210 of the disaster prevention unit 200), and thereby can supply the electric power necessary for maintaining the cooling function of the refrigerator 1 to the refrigerator main body 100 together with the 1 st auxiliary power supply device 310.

Specifically, the 2 nd auxiliary power supply device 320 includes, for example, a2 nd auxiliary power supply case 321, a battery unit 322, a terminal portion 323, a handle 324, a display device 325, a plurality of connectors 326, a power supply circuit portion 327, a voltage sensor VS2 (see fig. 6), a current sensor IS2 (see fig. 6), and a2 nd auxiliary power supply control portion 328.

The 2 nd auxiliary power supply case 321 is formed in a box shape, for example. The 2 nd auxiliary power supply case 321 has a1 st end 321a and a2 nd end 321 b. The 1 st end 321a is an end facing the 1 st auxiliary power supply device 310. The 2 nd end 321b is an end disposed at a position opposite to the 1 st end 321a and facing the front of the refrigerator 1. A battery unit 322 is housed in the 2 nd auxiliary power supply case 321. The battery unit 322 includes one or more secondary batteries.

The terminal portion 323 is provided at the 1 st end portion 321a of the 2 nd auxiliary power supply case 321. The terminal portion 323 is a terminal portion for connecting the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320, and is detachably connected to the 2 nd terminal portion 314 of the 1 st auxiliary power supply device 310. The 2 nd auxiliary power supply device 320 is connected to the 1 st auxiliary power supply device 310, and is electrically connected to the refrigerator main body 100 via the 1 st auxiliary power supply device 310, the main body connector 330, the power supply circuit portion 350, and the electrical connection member 403. Thereby, the battery unit 322 of the 2 nd auxiliary power supply device 320 is supplied with power from the refrigerator main body 100 and can be charged. The battery cell 322 of the 2 nd auxiliary power supply device 320 is electrically connected in parallel to the battery cell 312 of the 1 st auxiliary power supply device 310, for example. Instead of this, the battery cell 322 of the 2 nd auxiliary power supply device 320 may be electrically connected in series with the battery cell 312 of the 1 st auxiliary power supply device 310.

The handle 324 is provided at the 2 nd end 321b of the 2 nd auxiliary power supply casing 321. The handle 324 is a portion that is held by a user when the 2 nd auxiliary power supply device 320 is taken out from the case 210 of the disaster prevention unit 200 or when the 2 nd auxiliary power supply device 320 is carried. In a state where the 2 nd auxiliary power supply device 320 is housed in the case 210 of the disaster prevention unit 200, the handle 324 is positioned in the auxiliary power supply device main body 300U at a position closest to the opening 210a of the case 210. When the front cover 220 of the disaster prevention unit 200 is opened, the handle 324 is exposed to the outside of the case 210 toward the front of the refrigerator 1 through the opening 210a of the case 210.

The display device 325 is disposed at the 2 nd end 321b of the 2 nd preliminary power supply housing 321. The display device 325 is a liquid crystal display, an organic EL display, or the like, and has a display screen (display area) D4 on which images and/or characters can be displayed. The display device 325 may be an LED element or the like that indicates whether there is an abnormality and/or whether charging is necessary by color and/or a blinking state.

A plurality of connectors (power supply portions) 326 are provided at the 2 nd end portion 321b of the 2 nd auxiliary power supply case 321. The plurality of connectors 326 are connection portions to which various devices requiring electric power are connected. Power is supplied from the battery unit 322 of the 2 nd auxiliary power supply device 320 to the device connected to the connector 326. The connectors 326 include, for example, usb (universal Serial bus) ports, sockets corresponding to various specifications, cigarette lighters, and the like. However, the connector 326 is not limited to the above example, and may be a connector or the like corresponding to microsub or another type.

The power supply circuit portion 327 of the 2 nd auxiliary power supply device 320 is implemented by, for example, one or more power supply circuit boards, and is housed inside the 2 nd auxiliary power supply case 321. The power supply circuit 327 converts the electric power output from the battery unit 322 into electric power of a desired voltage and supplies the electric power to each connector 326. When one or more connectors 326 correspond to AC power, the power supply circuit portion 327 includes a DC-AC converter.

The voltage sensor VS2 detects the voltage value of the terminal voltage of the battery cell 322. The current sensor IS2 detects the current value of the current that IS charged to the battery cell 322 or discharged from the battery cell 322. The detection results of the voltage sensor VS2 and the current sensor IS2 are output to the 2 nd auxiliary power supply control unit 328. The detection results of the voltage sensor VS2 and the current sensor IS2 are output to the auxiliary power supply overall control unit 360 via the terminal units 323, 313, and 314 and the main body connector 330, for example.

The 2 nd auxiliary power supply control unit 328 is realized by, for example, one or more control boards, and is housed inside the 2 nd auxiliary power supply case 321. The power circuit portion 327 and the 2 nd auxiliary power control portion 328 may be implemented by one substrate. The 2 nd auxiliary power supply control unit 328 controls the entire 2 nd auxiliary power supply device 320. For example, the 2 nd auxiliary power supply control unit 328 controls the operations of the battery unit 322, the display device 325, and the power supply circuit unit 327.

The 2 nd auxiliary power supply control unit 328 can communicate with the auxiliary power supply overall control unit 360 via the terminal units 323, 313, and 314 and the main body connector 330, for example. The 2 nd auxiliary power supply control unit 328 can communicate with the control unit 190 of the refrigerator main body 100 via the terminal units 323, 313, and 314, the main body connector 330, and the electrical connection member 403, for example. However, instead of the above, the 2 nd auxiliary power supply control unit 328 may communicate with the auxiliary power supply overall control unit 360 and the control unit 190 of the refrigerator main body 100 by Bluetooth (registered trademark) or other wireless communication. The function of the 2 nd auxiliary power supply control unit 328 will be described in detail later.

Here, in the refrigerator main body 100, the widths WA and WB of the left and right refrigerator doors 131A and 131B are different from each other, and the boundary between the left and right refrigerator doors 131A and 131B is located on the left side with respect to the center in the lateral width direction of the refrigerator main body 100. As a result, the impact applied to the disaster prevention unit 200 when the left and right refrigerator doors 131A, 131B are closed is more likely to be transmitted to the left region than to the right region in the disaster prevention unit 200. Therefore, in the present embodiment, the power supply circuit portion 327 and the 2 nd auxiliary power supply control portion 328 of the 2 nd auxiliary power supply device 320 are disposed in the 2 nd auxiliary power supply casing 321 so as to be shifted to the right side with respect to the center of the 2 nd auxiliary power supply casing 321. Thus, the impact applied to the disaster prevention unit 200 when the refrigerator doors 131A and 131B are closed is not easily transmitted to the power circuit portion 327 and the 2 nd auxiliary power control portion 328.

[4.2.4 arrangement of the 1 st auxiliary power supply device and the 2 nd auxiliary power supply device ]

Fig. 9 is a cross-sectional view of the disaster prevention unit 200 shown in fig. 7 taken along line F9-F9. Fig. 10 is a cross-sectional view of the disaster prevention unit 200 shown in fig. 7 taken along line F10-F10.

In the present embodiment, the 2 nd auxiliary power supply device 320 is disposed in front of the 1 st auxiliary power supply device 310 inside the casing 210 of the disaster prevention unit 200, and is located closer to the opening 210a of the casing 210 than the 1 st auxiliary power supply device 310. The 2 nd auxiliary power supply device 320 can be taken out from the inside of the case 210 toward the front of the case 210 (i.e., toward the front of the refrigerator 1) without interfering with the 1 st auxiliary power supply device 310. In a state where the case 210 of the disaster prevention unit 200 is fixed to the refrigerator main body 100, the 2 nd auxiliary power supply device 320 can be taken out from the inside of the case 210 toward the front of the case 210.

From another point of view, the 1 st auxiliary power supply device 310 is larger than the 2 nd auxiliary power supply device 320 and is heavier than the 2 nd auxiliary power supply device 320. The 1 st auxiliary power supply device 310 is disposed behind the 2 nd auxiliary power supply device 320 in the housing 210 of the disaster prevention unit 200. This makes it easy for the center of gravity of the auxiliary power supply main body 300U to be located rearward.

In the present embodiment, the 1 st auxiliary power supply 310 and the 2 nd auxiliary power supply 320 are arranged at substantially the same height and are arranged in the front-rear direction of the refrigerator 1. This can lower the center of gravity of the auxiliary power supply main body 300U as compared with the case where either one of the 1 st auxiliary power supply 310 and the 2 nd auxiliary power supply 320 is disposed at a high position. In addition, when the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320 are disposed vertically, the 1 st auxiliary power supply device 310 is disposed below the 2 nd auxiliary power supply device 320 in the interior of the casing 210 of the disaster prevention unit 200. This can lower the center of gravity of the auxiliary power supply main body 300U.

[4.2.5 other constitution of the preliminary power supply device ]

Next, the main body connector 330 will be explained.

The main body connector 330 is provided at the rear end of the auxiliary power supply housing PS, for example, and faces the auxiliary power supply apparatus main body 300U in the front-rear direction of the refrigerator 1. The main body connector 330 has a terminal portion 331 detachably connected to the 1 st terminal portion 313 of the 1 st auxiliary power supply device 310. By pressing the 1 st auxiliary power supply device 310 toward the main body connector 330, the 1 st terminal portion 313 of the 1 st auxiliary power supply device 310 is connected to the terminal portion 331 of the main body connector 330. The main body connector 330 is electrically connected to the power circuit unit 350 of the auxiliary power supply 300.

Next, the fan 340 will be explained.

The fan 340 is disposed in the auxiliary power supply accommodation chamber PS. Here, the left and right side walls 213 and 214 of the casing 210 are provided with a plurality of air intake holes 411. On the other hand, a plurality of air discharge holes 412 are provided in the rear wall 215 of the case 210. The air intake hole 411 and the air exhaust hole 412 are air holes that communicate the auxiliary power supply housing chamber PS with the outside of the case 210. The arrangement of the air intake holes 411 and the air exhaust holes 412 is not limited to the above example, and may be provided in other portions of the housing 210.

The fan 340 sucks air in the preliminary power supply accommodation chamber PS and exhausts the sucked air to the outside of the case 210 through the exhaust hole 412. When the fan 340 is driven, air having a relatively low temperature outside the casing 210 flows into the auxiliary power supply accommodation chamber PS through the air intake hole 411. The air flowing into the auxiliary power supply housing chamber PS flows around the auxiliary power supply main body 300U, the power supply circuit unit 350, the auxiliary power supply overall control unit 360, and the like, thereby removing heat from the auxiliary power supply 300. The air having a temperature increased by taking away the heat of the preliminary power supply device 300 is discharged to the outside of the casing 210 by the cooling fan 340. This promotes heat dissipation from the auxiliary power supply device 300.

However, the auxiliary power supply 300 may not have the fan 340. Even when the fan 340 is not provided, the heat dissipation of the auxiliary power supply device 300 can be promoted to some extent by providing the vent hole for allowing the auxiliary power supply housing chamber PS to communicate with the outside of the case 210.

Next, the power supply circuit unit 350 will be explained.

The power supply circuit unit 350 is implemented by, for example, one or more power supply circuit boards, and is disposed at the rear end of the preliminary power supply housing chamber PS. The power supply circuit portion 350 is electrically connected to the refrigerator main body 100 via an electrical connection member 403. Power is supplied from the refrigerator main body 100 to the power supply circuit portion 350. The power supply circuit portion 350 converts the power supplied from the refrigerator main body 100 into dc power suitable for the voltage of the battery cells 312 and 322 of the auxiliary power supply device 300, and supplies the converted dc power to the battery cells 312 and 322. Thereby, the battery cells 312, 322 are charged. The function of the power supply circuit section 350 may be provided as a part of the power supply circuit section 180 of the refrigerator main body 100. In this case, the power supply circuit unit 350 of the auxiliary power supply device 300 may be omitted.

Next, the auxiliary power supply overall control unit 360 will be explained.

The auxiliary power supply overall control unit 360 is realized by one or more control boards, for example, and is disposed at the rear end of the auxiliary power supply housing chamber PS. The power supply circuit unit 350 and the auxiliary power supply overall control unit 360 may be realized by one substrate. The auxiliary power supply overall control unit 360 controls the entire auxiliary power supply device 300. For example, the auxiliary power supply overall control unit 360 controls the operation of the fan 340 and the power supply circuit unit 350. The auxiliary power supply overall control unit 360 can communicate with the control unit 190 of the refrigerator main body 100 via the electrical connection member 403. However, instead of the above, the auxiliary power supply overall control unit 360 may communicate with the control unit 190 of the refrigerator main body 100 by Bluetooth or other wireless communication. The function of the auxiliary power supply overall control unit 360 will be described in detail later.

The power supply circuit unit 350 and the entire auxiliary power supply control unit 360 are disposed in the auxiliary power supply housing chamber PS so as to be shifted to the right side with respect to the center of the auxiliary power supply housing chamber PS. Thus, the impact applied to the disaster prevention unit 200 when the refrigerator doors 131A and 131B are closed is not easily transmitted to the power circuit unit 350 and the auxiliary power supply overall control unit 360.

The storage unit 370 is formed of, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a ROM (Read-Only Memory). The details of the information stored in the storage unit 370 will be described later.

[4.2.6 center of gravity position of backup power supply device and disaster prevention unit ]

Next, the center of gravity position of the auxiliary power supply 300 and the disaster prevention unit 200 will be described with reference to fig. 3. In a state where all of the doors 130 of the refrigerator main body 100 are in the fully opened position, at least one of the gravity center position G3 of the auxiliary power supply device 300 and the gravity center position G2 of the disaster prevention unit 200 is located rearward with respect to the gravity center position G1 of the refrigerator main body 100. According to this configuration, even when the refrigerator 1 shakes due to an earthquake, the refrigerator 1 provided with the disaster prevention unit 200 is less likely to fall forward.

In the present embodiment, even in a state where all of the plurality of doors 103 of the refrigerator main body 100 are in the fully closed position, at least one of the center of gravity position G3 of the auxiliary power supply device 300 and the center of gravity position G2 of the disaster prevention unit 200 is located rearward with respect to the center of gravity position G1 of the refrigerator main body 100. According to this configuration, even if refrigerator 1 shakes due to an earthquake, stability of refrigerator 1 increases, and refrigerator 1 is less likely to fall forward.

From another point of view, as shown in fig. 9, a center position C3 of the auxiliary power supply 300 in the front-rear direction dimension (for example, a center position of the auxiliary power supply main body 300U in the front-rear direction dimension) is located rearward of a center position C1 of the refrigerator main body 100 in the front-rear direction dimension. Further, the center position C2 in the front-rear direction dimension of the disaster prevention unit 200 is located rearward with respect to the center position C1 in the front-rear direction dimension of the refrigerator main body 100.

From another different point of view, the distance L3a in the front-rear direction between the rear end of the auxiliary power supply device 300 (e.g., the rear end of the auxiliary power supply device main body 300U) and the rear end of the refrigerator main body 100 is smaller than the distance L3b in the front-rear direction between the front end of the auxiliary power supply device 300 (e.g., the front end of the auxiliary power supply device main body 300U) and the front end of the refrigerator main body 100. Further, a distance L2a in the front-rear direction between the rear end of the disaster prevention unit 200 (e.g., the rear end of the case 210) and the rear end of the refrigerator main body 100 is smaller than a distance L2b in the front-rear direction between the front end of the disaster prevention unit 200 (e.g., the front end of the front cover 220) and the front end of the refrigerator main body 100.

Fig. 11 is a side view of the refrigerator 1 which is inclined forward by a predetermined angle α (for example, 8 degrees) with respect to a horizontal plane. In a state where all of the doors 130 of the refrigerator main body 100 are at the fully opened position and the refrigerator 1 is tilted forward by a predetermined angle α (for example, 8 degrees), at least one of the gravity center position G3 of the preliminary power supply device 300 and the gravity center position G2 of the disaster prevention unit 200 is located rearward with respect to the gravity center position G1 of the refrigerator main body 100. According to this configuration, even when the refrigerator 1 shakes relatively largely due to an earthquake, the refrigerator 1 is less likely to fall forward.

In the present embodiment, even in a state where all of the doors 130 of the refrigerator main body 100 are at the fully closed position and the refrigerator 1 is tilted forward by the predetermined angle α (for example, 8 degrees), at least one of the gravity center position G3 of the preliminary power supply device 300 and the gravity center position G2 of the disaster prevention unit 200 is located rearward with respect to the gravity center position G1 of the refrigerator main body 100. With this configuration, stability of the refrigerator 1 is increased, and the refrigerator 1 is less likely to fall forward.

From another point of view, even in a state where the refrigerator 1 is tilted forward by a predetermined angle α (for example, 8 degrees), the center of gravity position G3 of the auxiliary power supply device 300 (or the center of gravity position G2 of the disaster prevention unit 200) is located rearward with respect to the front leg 118 of the refrigerator main body 100. According to this configuration, the weight of the disaster prevention unit 200 acts in the direction of restoring the tilt of the refrigerator 1. This makes the refrigerator 1 less likely to fall forward.

Next, another configuration of the disaster prevention unit 200 will be described.

[4.3 cushioning Member and support surface Forming Member ]

The cushioning member 240 and the bearing surface forming member 250 will be described with reference to fig. 7.

In the present embodiment, the buffer member 240 and the support surface forming member 250 are provided between the support portion 401 of the case 210 and the auxiliary power supply device 300.

The buffer member 240 is disposed between the support portion 401 of the case 210 and the auxiliary power supply main body 300U. The buffer member 240 is formed of an elastic body such as rubber or a spring, and is elastically deformable. The auxiliary power supply device main body 300U is supported by the support portion 401 of the case 210 via the buffer member 240. By providing the buffer member 240, it is possible to suppress the vibration of the refrigerator main body 100 (for example, the vibration of the compressor 145 of the refrigerator main body 100) from being transmitted to the auxiliary power supply apparatus main body 300U. Instead of the above example, the cushioning member 240 may be provided on the leg portion 280 described later. That is, a part of the leg portion 280 may be formed of the cushioning material 240.

The support surface forming member 250 is disposed between the buffer member 240 and the auxiliary power supply main body 300U. The bearing surface forming member 250 is formed of a member having a smaller friction coefficient than the cushioning member 240. The support surface forming member 250 is, for example, a metal plate, and is bonded to the entire upper surface of the cushioning member 240. The auxiliary power supply device main body 300U (1 st and 2 nd auxiliary power supply devices 310 and 320) can be inserted into the housing 210 and removed from the housing 210 by sliding in a substantially horizontal direction on the support surface forming member 250. This allows the second auxiliary power supply device 320 to be smoothly taken out when a disaster occurs and the first auxiliary power supply device 310 to be smoothly taken out when replacement is performed due to aging.

[4.4 receiving part for leakage ]

Next, the leakage receiving portion 260 will be described with reference to fig. 7.

In the present embodiment, a leakage receiving portion 260 is provided below the auxiliary power supply 300. The leakage receiving unit 260 is disposed below the auxiliary power supply device main body 300U in the auxiliary power supply housing chamber PS, for example. In the event that the battery cells 312 and 322 are damaged by shaking or the like due to an earthquake and the liquid leaks, the leaked liquid receiver 260 receives and accumulates the liquid. In the present embodiment, the leakage receiving portion 260 is provided between the pair of support portions 401 of the case 210 that supports the auxiliary power supply device 300. The leakage liquid receiving portion 260 is, for example, an oil pan, but is not limited thereto. For example, the leakage liquid receiver 260 may be a rib 265 (see fig. 10) or the like provided at the distal end portion of the housing 210 to prevent leakage liquid from flowing out of the housing 210 from the opening 210a of the housing 210.

[4.5 Standby Power supply fixing part ]

Next, the auxiliary power supply fixing unit 270 will be described with reference to fig. 9.

In the present embodiment, the auxiliary power supply fixing portion 270 is provided to fix the auxiliary power supply device 300. The auxiliary power supply fixing portion 270 includes, for example, a pair of 1 st power supply fixing portions 271 for fixing the 1 st auxiliary power supply device 310 and a pair of 2 nd power supply fixing portions 272 for fixing the 2 nd auxiliary power supply device 320.

The pair of 1 st power fixing parts 271 can move in a direction approaching each other and a direction separating each other along the lateral width direction of the refrigerator 1. After the 1 st auxiliary power supply device 310 is housed in the casing 210, the pair of 1 st power supply fixing portions 271 moves in a direction to approach each other. Thereby, the 1 st auxiliary power supply 310 is sandwiched between the 1 st power supply fixing portion 271 and the main body connector 330, and the position of the 1 st auxiliary power supply 310 is fixed. By operating a release button, not shown, the pair of 1 st power supply fixing parts 271 are moved in directions away from each other. This enables the 1 st auxiliary power supply device 310 to be detached.

Similarly, the pair of 2 nd power source fixing portions 272 can move in a direction approaching each other and a direction separating each other along the lateral width direction of the refrigerator 1. After the 2 nd auxiliary power supply device 320 is housed in the casing 210, the pair of 2 nd power supply fixing portions 272 move in a direction approaching each other. Thereby, the 2 nd auxiliary power supply device 320 is sandwiched between the 2 nd power supply fixing portion 272 and the 1 st auxiliary power supply device 310, and the position of the 2 nd auxiliary power supply device 320 is fixed. By operating a release button, not shown, the pair of 2 nd power supply fixing portions 272 move in directions away from each other. This enables the 2 nd auxiliary power supply device 320 to be detached.

[4.6 composition relating to foot ]

Next, the structure of leg portion 280 will be described with reference to fig. 7.

The pair of legs 280 is provided, for example, on the lower surface of the bottom wall 212 of the housing 210 of the disaster prevention unit 200, and extends in the front-rear direction of the housing 210. The leg 280 is placed on the top wall 111 of the refrigerator main body 100. By providing the leg 280, a gap S2 is thereby formed between the bottom wall 212 of the case 210 of the disaster prevention unit 200 and the top wall 111 of the refrigerator main body 100. Thereby, even when a part of the top wall 111 is heated by the influence of the heat radiation pipe 146, the heat transfer to the disaster prevention unit 200 can be suppressed.

Fig. 12 is a plan view showing the refrigerator main body 100 of the present embodiment. The top wall 111 of the refrigerator main body 100 has a guide member 420 provided on an upper surface of the top wall 111. The guide member 420 guides the leg 280 of the disaster prevention unit 200 toward the rear end of the ceiling wall 111. The guide member 420 includes, for example, a pair of rising portions 421 that rise so as to sandwich the leg portion 280 of the disaster prevention unit 200. The leg portion 280 of the disaster prevention unit 200 is guided toward the rear end portion of the top wall 111 by being guided by the pair of rising portions 421 so that the position in the lateral width direction of the refrigerator 1 is not shifted.

In the present embodiment, the refrigerator main body 100 and the disaster prevention unit 200 are carried into an installation place in a home in a state of being separated from each other. The disaster prevention unit 200 is installed in the refrigerator main body 100 after the refrigerator main body 100 is installed in an installation place in a home. For example, the disaster prevention unit 200 is installed on the refrigerator main body 100 from the front end of the top wall 111 of the refrigerator main body 100 installed in advance, and the foot 280 of the disaster prevention unit 200 is placed thereon. Then, the leg 280 of the disaster prevention unit 200 is slid along the upper surface of the top wall 111 of the refrigerator main body 100 while being guided by the guide member 420. Thus, even when the weight of the disaster prevention unit 200 is relatively heavy, the refrigerator 1 including the disaster prevention unit 200 can be relatively easily installed.

[4.7 casing fixing part ]

Next, the case fixing section 290 will be described with reference to fig. 9.

The housing fixing portion 290 includes a pair of 1 st housing fixing portions 291 and a pair of 2 nd housing fixing portions 292. The pair of 1 st case fixing portions 291 is provided at the front end of the case 210, for example. The 1 st case fixing part 291 has a1 st portion 291a fixed to the case 210 and a2 nd portion 291b along the top wall 111 of the refrigerator main body 100. The 2 nd part 291b has a screw insertion hole 293 (see fig. 7). The screw insertion hole 293 faces a screw hole 294 provided in the top wall 111 of the refrigerator main body 100 (e.g., the screw hole 294 provided in the reinforcement member 111 b). A fastening member (bolt, screw, or the like) 295 inserted through the screw insertion hole 293 is engaged with the screw hole 294, whereby the front end portion of the housing 210 is fixed to the top wall 111 of the refrigerator main body 100.

The pair of 2 nd case fixing portions 292 are provided at, for example, a rear end portion of the case 210. The 2 nd case fixing part 292 has a1 st portion 292a fixed to the case 210 and a2 nd portion 292b along the top wall 111 of the refrigerator main body 100. The 2 nd part 292b has a click hole 296. The top wall 111 has an engagement portion 297 detachably engaged with the engagement hole 296.

Fig. 13 is a sectional view showing an operation of the engaging portion 297. The engaging portion 297 has, for example, an inclined portion whose height increases as going from the front end toward the rear end. A rear end portion of the engaging portion 297 extends substantially in the vertical direction. The engaging portion 297 is provided swingably in the vertical direction with respect to the upper surface of the ceiling wall 111, and when the disaster prevention unit 200 climbs over the engaging portion 297, the engaging portion 297 sinks toward the inside of the ceiling wall 111 to allow the disaster prevention unit 200 to pass therethrough. On the other hand, when the engagement portion 297 is engaged with the engagement hole 296, the disaster prevention unit 200 is supported by the rear end portion of the engagement portion 297 and cannot move forward. Thereby, the rear end portion of the disaster prevention unit 200 is fixed. When a release button, not shown, is operated, the engagement portion 297 moves downward. Thereby, the disaster prevention unit 200 can be detached from the top wall 111 of the refrigerator main body 100.

[5. control section ]

Next, the control unit 190 of the refrigerator main body 100, the entire backup power supply control unit 360 of the disaster prevention unit 200, and the 2 nd backup power supply control unit 328 of the disaster prevention unit 200 will be described. In the present embodiment, the control unit 190, the auxiliary power supply overall control unit 360, and the 2 nd auxiliary power supply control unit 328 of the refrigerator main body 100 are collectively referred to as a control unit 500 of the refrigerator 1.

Fig. 14 is a block diagram showing the configuration of the control unit 500 of the refrigerator 1. All or a part of the functional units described below are realized by executing a program (software) stored in a storage Unit by a hardware processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). However, some or all of these functional units may be realized by hardware (Circuit unit; including Circuit) such as an ASIC (Application Specific Integrated Circuit), PLD (Programmable Logic Device), FPGA (Field Programmable Gate Array), or the like, or may be realized by cooperation of software and hardware.

[5.1 control part of refrigerator Main body ]

First, the control unit 190 of the refrigerator main body 100 will be described.

The control unit 190 of the refrigerator main body 100 includes, for example, a disaster detection unit 511, a cooling unit control unit 512, a charge/discharge control unit 513, an information acquisition unit 514, an information generation unit 515, and a display control unit 516. However, instead of being provided in the refrigerator main body 100, a part of these functional units may be provided as a part of the auxiliary power supply overall control unit 360 or the 2 nd auxiliary power supply control unit 328.

The disaster detection unit 511 detects occurrence of a disaster (for example, an earthquake) based on at least one of disaster information received via the network NW and a detection result of the acceleration sensor AS. The disaster detection unit 511 transmits a predetermined signal indicating occurrence of a disaster to the auxiliary power supply overall control unit 360 and the 2 nd auxiliary power supply control unit 328 when occurrence of a disaster is detected. The disaster detection unit 511 detects that a disaster (for example, heavy rain) is about to occur based on disaster information received via the network NW, and when detecting that a disaster is about to occur, transmits the predetermined signal to the auxiliary power supply overall control unit 360 and the 2 nd auxiliary power supply control unit 328. Hereinafter, for convenience of explanation, "a case where a disaster actually occurs" and "a case where a disaster is about to occur (a case where a possibility of occurrence of a disaster is high)" will be collectively referred to as "occurrence of a disaster".

The cooling unit controller 512 controls the driving of the refrigerating chamber fan 143, the freezing chamber fan 144, the compressor 145, and the like. For example, when the occurrence of a disaster is detected by the disaster detection unit 511, the cooling unit control unit 512 shifts to a low power mode in which the power consumption of the cooling unit 140 is suppressed.

The charge/discharge control unit 513 maintains the battery cells 312 and 322 of the auxiliary power supply device 300 in a charged state using the electric power supplied from the commercial power supply P to the refrigerator main body 100 in a normal state (non-disaster state). On the other hand, the charge/discharge control unit 513 discharges at least the battery unit 312 of the 1 st auxiliary power supply device 310 at the time of power failure, and drives the cooling unit 140 using the electric power obtained by the discharge. At this time, when the user operation indicating an instruction to supply power to the refrigerator main body 100 also to the battery cell 322 of the 2 nd auxiliary power supply device 320 is received by the operation unit 160 or the terminal device 2 of the refrigerator main body 100, the charge/discharge control unit 513 discharges the battery cell 322 of the 2 nd auxiliary power supply device 320 in addition to the battery cell 312 of the 1 st auxiliary power supply device 310, and drives the cooling unit 140 using the power obtained by the discharge.

Further, the charge/discharge control unit 513 may be configured to charge the battery cell 322 of the 2 nd auxiliary power supply device 320 with the electric power discharged from the battery cell 312 of the 1 st auxiliary power supply device 310 when the 2 nd auxiliary power supply device 320 is electrically connected to the 1 st auxiliary power supply device 310 after the remaining capacity has decreased due to use as a portable power supply.

The information acquisition unit 514 acquires information indicating the presence or absence of an abnormality in the auxiliary power supply apparatus 300, the state of degradation of the battery cells 312 and 322 of the auxiliary power supply apparatus 300, and the remaining capacity of the battery cells 312 and 322 of the auxiliary power supply apparatus 300 from the auxiliary power supply overall control unit 360. For example, the information acquisition unit 514 acquires the information from the auxiliary power supply overall control unit 360 at a predetermined cycle (for example, 1 time in 1 month) in a normal state. On the other hand, when the disaster detection unit 511 detects the occurrence of a disaster, the information acquisition unit 514 acquires information indicating the presence or absence of an abnormality in the auxiliary power supply apparatus 300 and the remaining capacity of the battery cells 312 and 322 of the auxiliary power supply apparatus 300 from the auxiliary power supply overall control unit 360.

The information generating unit 515 generates information to be displayed on at least one of 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, the display screen D4 of the display device 325 of the auxiliary 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") based on the information acquired by the information acquiring unit 514. For example, the information generating unit 515 generates at least one of information indicating the presence or absence of an abnormality in the auxiliary power supply devices 310 and 320, information relating to the deterioration states of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320, and information relating to the remaining capacities of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320, as information to be displayed in the display area D.

Here, the "information on the deterioration state of the battery cells 312 and 322" includes, for example, information indicating at least one of the replacement reference time of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320 and whether or not the battery cells 312 and 322 need to be replaced. The "information on the remaining capacities of the battery cells 312 and 322" includes, for example, at least one of a sustainable operation time (how long the refrigerator main body 100 can be continuously operated) in a case where the refrigerator main body 100 is operated by the electric power supplied from the 1 st auxiliary power supply device 310 and information indicating the number of times the terminal device 2 or another terminal device is chargeable by the electric power supplied from the 2 nd auxiliary power supply device 320. The "information on the remaining capacity of the battery cells 312 and 322" may include information indicating a sustainable operation time of the refrigerator main body 100 when the refrigerator main body 100 is operated by the electric power supplied from both the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320.

In a normal state, the information generating unit 515 generates, as information to be displayed in the display area D, information indicating whether or not the auxiliary power supply device 310 or 320 is abnormal, the deterioration state of the battery cell 312 or 322 of the auxiliary power supply device 310 or 320, and information indicating the remaining capacity of the battery cell 312 or 322 of the auxiliary power supply device 310 or 320 at the predetermined cycle. On the other hand, when the disaster detection unit 511 detects the occurrence of a disaster, the information generation unit 515 generates information indicating whether there is a malfunction in the auxiliary power supply devices 310 and 320 and the remaining capacities of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320 as information to be displayed in the display area D.

When the information to be displayed in the display area D is generated by the information generating unit 515, the display control unit 516 transmits the information to the display device 150 of the refrigerator main body 100, the display device 2A of the terminal device 2, the display device 325 of the 2 nd auxiliary power supply device 320, and the display device provided behind the front cover 220 of the disaster prevention unit 200, and displays the information in the display area D.

[5.2 Standby Power supply Overall control section of disaster prevention Unit ]

Next, the auxiliary power supply overall control unit 360 of the auxiliary power supply device 300 will be described.

The auxiliary power supply overall control unit 360 includes, for example, an abnormality detection unit 521, a deterioration detection unit 522, and a remaining capacity detection unit 523. However, instead of being provided in the auxiliary power supply device 300, a part of these functional units may be provided as a part of the control unit 190 or the 2 nd auxiliary power supply control unit 328 of the refrigerator main body 100.

The abnormality detector 521 performs, for example, test discharge of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320, and detects the presence or absence of an abnormality in the auxiliary power supply devices 310 and 320 based on the detection results of the voltage sensors VS1 and VS2 and the current sensors IS1 and IS 2. The detection result of the abnormality detection unit 521 is transmitted to the control unit 190 of the refrigerator main body 100 and the 2 nd auxiliary power supply control unit 328.

When the test discharge of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320 IS performed, the deterioration detecting unit 522 detects the deterioration state of the battery cells 312 and 322 based on the detection results of the voltage sensors VS1 and VS2 and the current sensors IS1 and IS 2. Here, the storage unit 370 of the auxiliary power supply device 300 stores information indicating the degradation characteristics of the battery cells 312 and 322 (for example, the relationship between the degradation degree and the combination of the integrated value of the discharge amount and the voltage drop amount of the terminal voltage). The deterioration detecting unit 522 detects the deterioration state of the battery cells 312 and 322 based on the integrated value of the discharge amount from the battery cells 312 and 322 detected in the test discharge, the voltage drop amount of the terminal voltage of the battery cells 312 and 322, and the information indicating the deterioration characteristic stored in the storage unit 370. However, the method of detecting the deterioration state is not limited to the above example, and various known methods can be used. The detection result of the degradation detection unit 522 is transmitted to the control unit 190 of the refrigerator main body 100 and the 2 nd auxiliary power supply control unit 328.

The remaining capacity detector 523 detects the remaining capacity of the battery cells 312 and 322 based on the detection results of the terminal voltages of the battery cells 312 and 322 of the auxiliary power supply devices 310 and 320 detected by the voltage sensors VS1 and VS 2. 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 the remaining capacity detecting unit 523 is transmitted to the control unit 190 and the 2 nd auxiliary power supply control unit 328 of the refrigerator main body 100.

In a normal state, the abnormality detector 521, the deterioration detector 522, and the remaining capacity detector 523 perform test discharge of the battery cells 312 and 322 at the predetermined cycle described above to detect the presence or absence of abnormality and/or a deteriorated state of the battery cells 312 and 322, and the remaining capacity of the battery cells 312 and 322. On the other hand, when the disaster detector 511 of the refrigerator main body 100 receives a predetermined signal indicating occurrence of a disaster, the abnormality detector 521 and the remaining capacity detector 523 detect presence or absence of an abnormality in the battery cells 312 and 322 and remaining capacity of the battery cells 312 and 322 based on, for example, presence or absence of a change in terminal voltage of the battery cells 312 and 322, and transmit the detection results to the controller 190 and the No. 2 auxiliary power supply controller 328 of the refrigerator main body 100. For example, when receiving a predetermined signal indicating the occurrence of an earthquake from the disaster detector 511 of the refrigerator main body 100, the abnormality detector 521 detects the presence or absence of an abnormality in the battery cells 312 and 322 after the earthquake occurs (after the detection result of the acceleration sensor AS has converged to within the threshold), and transmits the detection result to the controller 190 and the 2 nd auxiliary power supply controller 328 of the refrigerator main body 100.

[5.3 the 2 nd reserve power supply control section of the disaster prevention unit ]

Next, the 2 nd auxiliary power supply control unit 328 of the disaster prevention unit 200 will be described.

The 2 nd auxiliary power supply control unit 328 includes, 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, instead of being provided in the No. 2 auxiliary power supply device 320, a part of these functional units may be provided as a part of the control unit 190 of the refrigerator main body 100 or the auxiliary power supply overall control unit 360.

When the 2 nd auxiliary power supply device 320 is used as a portable power supply and a device to which power is supplied is connected to the connector 326, the discharge control unit 531 discharges the battery cell 322 of the 2 nd auxiliary power supply device 320 and supplies the device with power obtained by the discharge.

For example, when the 2 nd auxiliary power supply device 320 is used as a portable power supply, the remaining capacity detection unit 532 detects the remaining capacity of the battery cell 322 based on the detection result of the terminal voltage of the battery cell 322 of the 2 nd auxiliary power supply device 320 detected by the voltage sensor VS 2. 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 2 nd auxiliary power supply device 320 is used as a portable power supply, the information generating unit 533 generates information to be displayed on the display screen D4 of the 2 nd auxiliary power supply device 320 based on the detection result of the remaining capacity detecting unit 532 and the like.

When the information generating unit 533 generates the information to be displayed on the display screen D4, the display control unit 534 transmits the information to the display device 325, and displays the information on the display screen D4. When receiving information to be displayed on the display screen D4 from the control unit 190 or the auxiliary power supply overall control unit 360 of the refrigerator main body 100, the display control unit 534 transmits the information to the display device 325 and displays the information on the display screen D4.

With the above configuration, user convenience can be improved. That is, in the present embodiment, the case 210 of the disaster prevention unit 200 disposed above the refrigerator main body 100 is disposed, and the auxiliary power supply device 300 is housed inside the case 210. With this configuration, it is possible to secure electricity in the event of a disaster by using the space above the refrigerator main body 100, which is likely to become a dead space.

In the present embodiment, the auxiliary power supply device 300 includes a1 st auxiliary power supply device 310 that supplies power to the refrigerator main body 100 when power fails. With this configuration, even when a power failure occurs, the refrigerator main body 100 can be continuously operated, and food items for several days until recovery can be easily secured. In the present embodiment, the auxiliary power supply device 300 includes a2 nd auxiliary power supply device 320 that can be used as a portable power supply. With this configuration, the 2 nd auxiliary power supply device 320 can be used in a desired place in a home, an evacuation facility, or the like.

In the present embodiment, the 2 nd auxiliary power supply device 320 is connected to the 1 st auxiliary power supply device 310, and is supplied with power from the refrigerator main body 100 via the 1 st auxiliary power supply device 310, whereby charging is possible. With this configuration, the 2 nd auxiliary power supply device 320 can be easily disposed in front of the 1 st auxiliary power supply device 310, as compared with a case where an electrical connection portion for the 2 nd auxiliary power supply device 320 is provided in the main body connector 330. When the 2 nd auxiliary power supply device 320 is disposed in front of the 1 st auxiliary power supply device 310, the ease of taking out the 2 nd auxiliary power supply device 320 is improved.

In the present embodiment, the 1 st auxiliary power supply device 310 is heavier than the 2 nd auxiliary power supply device 320, and is disposed behind the 2 nd auxiliary power supply device 320 or below the 2 nd auxiliary power supply device 320. With this configuration, the center of gravity of the disaster prevention unit 200 is easily located rearward or downward, and the refrigerator 1 including the disaster prevention unit 200 is easily stabilized.

Next, several modifications of embodiment 1 will be explained. In each modification, the configuration other than that described below is the same as that of embodiment 1.

(modification 1)

Fig. 15 is a side view of the refrigerator 1 according to modification 1, shown in a partial cross section. Here, the refrigerator 1 is often disposed along a wall W of a house. A fan, not shown, for promoting heat dissipation of the compressor 145 is provided in the machine chamber at the bottom of the refrigerator main body 100. The air blown by the fan rises through a chimney effect in a gap between the rear wall 115 of the refrigerator main body 100 and the wall W. That is, the air blown by the fan rises along the rear wall 115 of the refrigerator main body 100.

Fig. 16 is a sectional view showing the disaster prevention unit 200 according to the present modification. In the present modification, a plurality of air intake holes 411 are provided in the rear wall 215 of the housing 210. On the other hand, the plurality of air discharge holes 412 are provided in the left and right side walls 213 and 214 of the case 210.

In the present modification, the disaster prevention unit 200 includes, for example, a guide member 601, and the guide member 601 is provided on the rear wall 215 of the casing 210 and guides at least a part of the air rising along the rear wall 115 of the refrigerator main body 100 toward the air intake hole 411 of the casing 210. The guide member 601 is provided, for example, at a position slightly above the suction hole 411. The guide member 601 protrudes rearward of the case 210 and is located above the gap between the rear wall 115 of the refrigerator main body 100 and the wall W. The air rising along the rear wall 115 of the refrigerator main body 100 is guided to the air intake hole 411 by changing the flow direction by colliding with the guide member 601, and is introduced into the auxiliary power supply accommodating chamber PS through the air intake hole 411. In the present modification, the fan 340 may be provided or omitted.

According to this configuration, by providing the guide member 601, at least a part of the air rising along the rear wall 115 of the refrigerator main body 100 by the chimney effect can be efficiently taken into the inside of the case 210. This can improve the heat dissipation of the auxiliary power supply device 300.

In the present modification, when fan 340 is provided, air can be taken in from air intake hole 411 by driving fan 340, and air in the gap between rear wall 115 of refrigerator main body 100 and wall W can be positively introduced into case 210. If the air in the gap between the rear wall 115 of the refrigerator main body 100 and the wall W can be positively introduced into the casing 210, the air is less likely to stay in the gap between the rear wall 115 of the refrigerator main body 100 and the wall W, 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. This can improve the heat dissipation performance of the refrigerator main body 100.

(modification 2)

Fig. 17 is a sectional view showing the disaster prevention unit 200 according to the modification 2. In the present modification, embossing (embossing) is applied to the outer surface of the rear wall 115 of the housing 210 of the disaster prevention unit 200. That is, the outer surface of the rear wall 115 of the housing 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 this configuration, a part of the air rising along the rear wall 115 of the refrigerator main body 100 is likely to be in a turbulent state, and the air is likely to smoothly pass through the gap between the rear wall 215 of the case 210 of the disaster prevention unit 200 and the wall W to the upper side. This can improve the circulation of air around the refrigerator 1, and improve the heat radiation performance of the refrigerator 1.

(modification 3)

Fig. 18 is a sectional view showing a refrigerator 1 according to modification 3. In the present modification, the top wall 111 of the refrigerator main body 100 has the 1 st region R1 and the 2 nd region R2. The 1 st region R1 is located below the auxiliary power supply device 300 (below the auxiliary power supply housing chamber PS). The 2 nd region R2 is located at a place separated from the 1 st region R1. That is, the 2 nd region R2 does not overlap the auxiliary power supply device 300 in the vertical direction.

In this modification, the thickness T1 of the heat insulator 110c in at least a part of the 1 st region R1 of the top wall 111 is smaller than the thickness T2 of the heat insulator 110c in the 2 nd region R2 of the top wall 111. For example, the heat insulating material 110c is thinned in a region between the pair of legs 280 of the disaster prevention unit 200 in the 1 st region R1. In the present modification, the vacuum heat insulator 111a is not provided at least in the region where the heat insulator 110c is thin.

According to this configuration, the upper surface of the top wall 111 of the refrigerator main body 100 is easily cooled by the cold air of the storage chamber 120, and the temperature of the upper surface of the top wall 111 is not easily increased. Therefore, the air temperature in the gap S2 between the top wall 111 of the refrigerator main body 100 and the disaster prevention unit 200 is not easily increased. As a result, the heat dissipation of the auxiliary power supply device 300 can be improved.

(modification 4)

Fig. 19 is a sectional view showing a refrigerator 1 according to a4 th modification. In the present modification, the thickness T1 of the heat insulator 110c (the sum of the thickness T1 of the heat insulator 110c on the upper side of the vacuum heat insulator 111a and the thickness T2 of the heat insulator 110c on the lower side of the vacuum heat insulator 111a in the case where the heat insulator 110c is present so as to sandwich the vacuum heat insulator 111a or more) in at least a part of the 1 st region R1 of the ceiling wall 111 is greater than the thickness T2 of the heat insulator 110c in the 2 nd region R2 of the ceiling wall 111. For example, the heat insulator 110c is thicker in a region larger than a region between the pair of legs 280 of the disaster prevention unit 200 in the lateral width direction of the refrigerator 1.

With this configuration, when the auxiliary power supply device 300 generates heat, heat of the auxiliary power supply device 300 can be prevented from being transferred to the inside of the storage chamber 120. This can suppress a temperature rise in the storage chamber 120.

(modification 5)

Fig. 20 is a sectional view showing a refrigerator 1 according to a modification example 5. In the present modification, the bottom wall 212 of the housing 210 of the disaster prevention unit 200 has heat insulation properties. In other words, the casing 210 has a heat insulating wall (bottom wall 212) between the auxiliary power supply accommodation chamber PS and the refrigerator main body 100. The bottom wall 212 includes, for example, a1 st portion 212a made of synthetic resin and a2 nd portion 212b formed of a member having heat insulating properties, and the 1 st portion 212a and the 2 nd portion 212b are vertically overlapped. The 2 nd part 212b is formed of, for example, a vacuum heat insulator. The 2 nd portion 212b may be formed of a foamed heat insulating material such as foamed urethane.

With this configuration, when the auxiliary power supply 300 generates heat, heat of the auxiliary power supply 300 can be prevented from being transferred to the inside of the storage chamber 120. This can suppress a temperature rise in the storage chamber 120.

(6 th modification)

Fig. 21 is a sectional view showing a refrigerator 1 according to modification 6. In the present modification, the bottom wall 212 of the housing 210 of the disaster prevention unit 200 has a pair of inclined surfaces 611 and 612. The inclined surfaces 611 and 612 are located at upper positions as they go to the outer peripheral side of the housing 210. In the present modification, the bottom wall 212 of the housing 210 has a flat surface 613 located at 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. For example, the total of lateral width W1 of left inclined surface 611 and lateral width W2 of right inclined surface 612 is substantially the same as or larger than lateral width W3 of flat surface 613.

With this configuration, air is easily discharged to the outer peripheral side (left side or right side) of the case 210 in the gap S2 between the case 210 of the disaster prevention unit 200 and the top wall 111 of the refrigerator main body 100. This makes it difficult for air to accumulate in the gap S2, and relatively cool air is likely to flow into the gap S2. This can improve the heat dissipation performance of the auxiliary power supply device 300 and suppress a temperature rise in the storage chamber 120.

(embodiment 2)

Next, the refrigerator 1 of embodiment 2 will be explained. The present embodiment is different from embodiment 1 in that the disaster prevention unit 200 includes disaster prevention product storage rooms GS1, GS2, and GS3 capable of storing the disaster prevention products 700. Configurations other than those described below are the same as those of embodiment 1.

Fig. 22 is a front view of the refrigerator 1 according to embodiment 2. In the present embodiment, the disaster prevention unit 200 has a larger housing 210 than that of embodiment 1. The widthwise center of the case 210 substantially coincides with the widthwise center of the refrigerator main body 100. For example, the housing 210 has 4 receiving chambers.

Fig. 23 is a sectional view showing the disaster prevention unit 200 according to the present embodiment. In the present embodiment, the casing 210 includes disaster prevention product storage chambers (disaster prevention product storage spaces) GS1, GS2, and GS3 of the 1 st to 3 rd in addition to the auxiliary power supply storage chamber PS for storing the auxiliary power supply device 300. The 4 storage chambers including the disaster prevention product storage chambers GS1, GS2, GS3 and the auxiliary power supply storage chamber PS are partitioned by partition walls 217 provided inside the casing 210. For example, the partition wall 217 is made of synthetic resin and has electrical insulation. Accordingly, even if the backup power supply device 300 is damaged by, for example, shaking of an earthquake, electrical safety inside the disaster prevention product storage chambers GS1, GS2, and GS3 can be ensured more reliably.

Fig. 24 is a sectional view of the disaster prevention unit 200 shown in fig. 23 taken along line F24-F24. Figure 25 is a cross-sectional view of the disaster prevention unit 200 shown in figure 23 taken along line F25-F25. The 1 st to 3 rd disaster prevention product storage chambers GS1, GS2, and GS3 have substantially the same depth as the reserve power supply storage chamber PS in the front-rear direction of the refrigerator main body 100, for example.

Disaster prevention products (disaster prevention tools) 700 are housed in the disaster prevention product housing rooms GS1, GS2, and GS3, respectively. Examples of the disaster prevention product 700 include, but are not limited to, a resin bottle for drinking water, foods (dry bread, canned food, retort pouch food, fast food, candy, chocolate, etc.) that can be stored for a long period of time, a plastic box for water supply, a gas range, a gas cylinder, a portable radio, a safety cap, a disaster prevention hood, a thick glove, a flashlight, a multipurpose knife, a mask, a paper towel, a wet tissue, a simple toilet, a kit for first aid, a medicine, a portable warmer, a lighter, a match, and a candle. Some or all of these are stored in disaster prevention product storage rooms GS1, GS2, and GS3 in a state where emergency carry bags are put in.

Next, referring back to fig. 23, the arrangement relationship between the 3 disaster prevention product storage chambers GS1, GS2, and GS3 and the auxiliary power supply storage chamber PS will be described. In the present embodiment, the 1 st and 2 nd disaster prevention product storage chambers GS1 and GS2 are disposed on the left side of the auxiliary power supply storage chamber PS. The 1 st disaster prevention product storage room GS1 and the auxiliary power supply storage room PS are arranged at substantially the same height. The 2 nd disaster prevention product storage chamber GS2 is disposed above the 1 st disaster prevention product storage chamber GS1 and at a position higher than the auxiliary power supply storage chamber PS. The 3 rd disaster prevention product storage room GS3 is disposed above the auxiliary power supply storage room PS. The 2 nd disaster prevention product storage room GS2 and the 3 rd disaster prevention product storage room GS3 are disposed at the same height.

In other words, the auxiliary power supply accommodation chamber PS is located at the lowermost position among the 4 accommodation chambers including the 1 st to 3 rd disaster prevention product accommodation chambers GS1, GS2, GS3 and the auxiliary power supply accommodation chamber PS. Here, the weight of the auxiliary power supply device 300 is heavier than the disaster prevention article 700. Therefore, if the auxiliary power supply housing chamber PS is provided below, the center of gravity of the disaster prevention unit 200 becomes low, and the disaster prevention unit 200 is easily stabilized.

From another point of view, the above arrangement is such that the auxiliary power source accommodating chamber PS is disposed offset to the right side with respect to the center of the housing 210 in the lateral width direction (opposite to the side where the boundary between the left and right refrigerating compartment doors 131A and 131B is offset to the center of the refrigerator main body 100 in the lateral width direction). Thus, when the refrigerator doors 131A and 131B are closed, the impact applied to the disaster prevention unit 200 is not easily transmitted to the auxiliary power supply device 300. In the present embodiment, the entire auxiliary power source accommodating chamber PS is disposed offset to the right with respect to the boundary between the left and right refrigerating chamber doors 131A and 131B to a position where the boundary between the left and right refrigerating chamber doors 131A and 131B does not overlap in the front-rear direction of the refrigerator 1.

With this configuration, it is possible to secure electricity and food in the event of a disaster by using the space above the refrigerator main body 100, which is likely to become a dead space. In addition, the disaster prevention product storage room does not need to be provided with 3, and may be provided with 1 or 2, or may be provided with 4 or more.

(embodiment 3)

Next, a refrigerator 1 according to embodiment 3 will be described. The present embodiment is different from embodiment 2 in that the disaster prevention unit 200 includes an illumination device housing chamber LS in which the illumination device 800 can be housed. Configurations other than those described below are the same as those of embodiment 2.

Fig. 26 is a sectional view showing the disaster prevention unit 200 according to embodiment 3. In the present embodiment, the housing 210 includes an illumination device housing chamber (illumination device housing space) LS for housing the illumination device 800, in addition to the auxiliary power supply housing chamber PS and the 1 st to 3 rd disaster prevention product housing chambers GS1, GS2, and GS 3.

In the present embodiment, the lighting device housing chamber LS is disposed on the right side of the auxiliary power supply housing chamber PS. The lighting device housing chamber LS and the auxiliary power supply housing chamber PS are disposed at substantially the same height. From another point of view, the lighting device housing chamber LS is disposed below the 3 rd disaster prevention product housing chamber GS 3. With this configuration, the auxiliary power supply device 300 can be easily disposed at a position close to the center of the housing 210 in the lateral width direction, as compared with the case where the lighting device housing LS is disposed between the 1 st disaster prevention product housing GS1 and the auxiliary power supply housing PS. This can improve the stability of the refrigerator 1 including the disaster prevention unit 200 in the lateral direction.

The disaster prevention product storage room GS3 and the lighting device storage room LS are partitioned from each other by a partition wall 217 provided inside the housing 210. On the other hand, in the present embodiment, a partition wall 218 is provided between the preliminary power supply housing chamber PS and the lighting device housing chamber LS so as to be detachable from the housing 210. The partition wall 218 is made of synthetic resin and has electrical insulation. If the partition wall 218 is provided between the auxiliary power supply housing chamber PS and the lighting device housing chamber LS, electrical safety inside the lighting device housing chamber LS can be reliably ensured even if the auxiliary power supply 300 is damaged by, for example, shaking of an earthquake. Further, if the partition wall 218 is detachable from the housing 210, the 1 st auxiliary power supply 310 can be removed to the front of the housing 210 even when the 1 st auxiliary power supply 310 is larger than the 2 nd auxiliary power supply 320.

In the present embodiment, the lighting device 800 can be used as a portable lamp separately from the refrigerator main body 100 (separately from the case 210 of the disaster prevention unit 200). That is, the lighting device 800 can be carried to a place different from the place where the refrigerator main body 100 is installed and used.

Fig. 27 is a perspective view showing a lighting device 800 according to the present embodiment. The lighting device 800 includes, for example, a lighting device case 801, a battery 802 (see fig. 28), a terminal unit 803, a1 st lamp unit 804, a2 nd lamp unit 805, a handle 806, and a control unit 807.

The lighting device case 801 is formed in an elongated box shape, for example. The lighting device housing 801 has a1 st end 801a and a2 nd end 801 b. The 1 st end 801a is an end facing the 1 st auxiliary power supply device 310 (see fig. 28). End 801b 2 is located opposite to end 801a 1 and is located toward the front of refrigerator 1. The battery 802 is housed inside the lighting device case 801.

The terminal portion 803 is provided at the 1 st end portion 801a of the lighting device case 801. The terminal unit 803 is, for example, a terminal unit for connecting the lighting device 800 to the 1 st auxiliary power supply device 310, and is detachably connected to the 3 rd terminal unit 316 of the 1 st auxiliary power supply device 310, which will be described later. The lighting device 800 is connected to the 1 st auxiliary power supply device 310, and is electrically connected to the refrigerator main body 100 via the 1 st auxiliary power supply device 310, the main body connector 330, the power supply circuit portion 350, and the electrical connection member 403. Thereby, the battery 802 of the lighting device 800 is supplied with power from the refrigerator main body 100 and can be charged. In the present embodiment, the battery 802 of the lighting apparatus 800 is chargeable by being supplied with electric power from the power supply circuit unit 350.

The 1 st lamp portion 804 is provided at, for example, the 2 nd end portion 801b of the lighting device case 801. The 1 st lamp portion 804 functions as an emergency lamp. For example, the 1 st lamp unit 804 has a hemispherical lens 804a provided on the end face of the 2 nd end 801b of the lighting device case 801 and protruding forward. The 1 st lamp part 804 has a hemispherical lens 804a, and thus can emit light radially in front of and around the 1 st lamp part 804. Further, by forming the lens 804a in a hemispherical shape, part of the light emitted from the 1 st lamp portion 804 is emitted further to the rear (the 1 st end 801a side) than the end face of the 2 nd end 801b of the lighting device case 801.

The 2 nd lamp section 805 is provided between the 1 st end 801a and the 2 nd end 801b in the lighting device case 801, for example. Lamp part 2 805 is a lamp larger than lamp part 1 804. For example, the 2 nd lamp unit 805 is turned on when the lighting device 800 is used as a portable lamp and requires a larger amount of light than the 1 st lamp unit 804.

The handle 806 is disposed at the 2 nd end 801b of the luminaire housing 801. The handle 806 is a portion that is held by a user when the lighting device 800 is taken out from the housing 210 of the disaster prevention unit 200 and when the lighting device 800 is carried. In a state where the lighting device 800 is housed in the housing 210 of the disaster prevention unit 200, the handle 806 is positioned in the lighting device 800 at a position closest to the opening 210a of the housing 210. When the front cover 220 of the disaster prevention unit 200 is opened, the handle 806 is exposed to the outside of the housing 210 toward the front of the housing 210 through the opening 210a of the housing 210.

The control unit 807 is realized by one or more control boards, for example. Controller 807 controls lighting of lamp 1 portion 804 and lamp 2 portion 805. In the present embodiment, when occurrence of a disaster is detected based on at least one of disaster information received via the network NW and a detection result of the acceleration sensor AS, the disaster detector 511 of the refrigerator main body 100 further transmits a predetermined signal indicating occurrence of a disaster to the controller 807 of the lighting apparatus 800. When receiving the predetermined signal, controller 807 of lighting apparatus 800 turns on lamp portion 1 804 for a predetermined time until the erasing operation is performed.

Fig. 28 is a sectional view of the disaster prevention unit 200 shown in fig. 26 taken along line F28-F28. In the present embodiment, the width W4 in the lateral direction of the 1 st auxiliary power supply device 310 is larger than the width W5 in the lateral direction of the 2 nd auxiliary power supply device 320. The 1 st auxiliary power supply 310 has a1 st area 310a and a2 nd area 310 b. The 1 st section 310a faces the 2 nd preliminary power supply device 320 in the front-rear direction of the refrigerator 1. The 1 st region 310a has a2 nd terminal portion 314 connected to the 2 nd auxiliary power supply device 320. On the other hand, the 2 nd area 310b faces the lighting device 800 in the front-rear direction of the refrigerator 1. The 2 nd region 310b has a3 rd terminal portion 316 connected to the lighting device 800.

In the present embodiment, at least a part of the 1 st lamp portion 804 of the lighting device 800 is located forward of the tip end portion of the auxiliary power supply device 300 (for example, the 2 nd end portion 321b of the 2 nd auxiliary power supply device 320). Thus, the 1 st lamp unit 804 can illuminate the handle 324, the display screen D4, the connector 326, and the like of the 2 nd auxiliary power supply device 320. For example, at least a part of the 1 st lamp unit 804 is located forward of the front end of the partition wall 218, and the partition wall 218 is located between the lighting device housing chamber LS and the auxiliary power supply housing chamber PS. Thus, the 1 st lamp unit 804 can illuminate the handle 324, the display screen D4, the connector 326, and the like of the 2 nd auxiliary power supply device 320 without being obstructed by the partition wall 218.

At least a part of the 1 st lamp unit 804 is located forward of the front end of the partition wall 217, and the partition wall 217 is located between the disaster prevention product storage chambers GS1, GS2, GS3 and the auxiliary power supply storage chamber PS. Thus, the 1 st lamp unit 804 can illuminate the front end portions of the 1 st to 3 rd disaster prevention product storage chambers GS1, GS2, and GS3 without being obstructed by the partition wall 217.

In the present embodiment, the charge/discharge control unit 513 of the refrigerator main body 100 may be configured to charge the battery 802 of the lighting device 800 with the electric power discharged from the battery unit 312 of the 1 st auxiliary power supply device 310 when the lighting device 800 is used as a portable lamp and the remaining capacity of the battery 802 is reduced and then the lighting device is electrically connected to the 1 st auxiliary power supply device 310.

With this configuration, it is possible to secure electricity, food, and illumination in the event of a disaster by using the space above the refrigerator main body 100, which is likely to become a dead space. The configuration of the lighting device 800 is not limited to the above example. For example, lighting device 800 may include only one of lamp 1 and lamp 2, 804 and 805. The lighting device 800 is not limited to a lighting device that can be used as a portable lamp, and may be a lighting device that is fixed to the housing 210 of the disaster prevention unit 200.

Next, several modifications of embodiment 3 will be described. In each modification, the configuration other than the configuration described below is the same as that of embodiment 3.

(modification 1)

Fig. 29 is a diagram showing the refrigerator 1 according to modification 1. Fig. 29 (b) is a sectional view taken along the line b-b in fig. 29 (a). In the present modification, the front cover 220 is formed of a translucent member. The "translucent member" may be transparent, translucent, or colored. For example, the front cover 220 is formed as a light guide plate. Namely, the front cover 220 has: the 1 st surface 220a facing forward; a2 nd surface 220b located at a position opposite to the 1 st surface 220 a; and a light-transmitting portion 220c located between the 1 st surface 220a and the 2 nd surface 220 b. The 2 nd surface 220b is provided with irregularities for diffusing light.

In the present modification, the front cover 220 of the disaster prevention unit 200 has the notch C that avoids the lighting device 800. The front end of the lighting device 800 protrudes outside the housing 210. Lamp part 1 804 of lighting device 800 is disposed in cutout C of front cover 220, below a portion of front cover 220, and on a side of a portion of front cover 220. The lighting device 800 emits light toward the light-transmitting portion 220c of the front cover 220 from below or a side of the front cover 220. The light incident on the light-transmitting portion 220c of the front cover 220 travels inside the front cover 220 and is diffused by the 2 nd surface 220 b. This makes the entire front cover 220 bright. With this configuration, the location of the disaster prevention unit 200 can be easily known at the time of power failure.

(modification 2)

Fig. 30 is a sectional view showing the disaster prevention unit 200 according to the modification 2. In the present modification, the front end of the upper wall 211 of the case 210 is located rearward of the front end of the bottom wall 212 of the case 210. In the present modification, the front cover 220 is disposed obliquely to the vertical direction so as to be positioned further rearward as it goes upward. With this configuration, the feeling of pressure when viewed from the front of the refrigerator 1 can be reduced.

(embodiment 4)

Next, a refrigerator 1 according to embodiment 4 will be described. The present embodiment is different from embodiment 1 in that the auxiliary power supply 300 is disposed between the main freezer 125 and the floor surface F. The configuration other than the configuration described below is the same as that of embodiment 1.

Fig. 31 is a perspective view showing the refrigerator 1 according to embodiment 4. In the present embodiment, heat insulating frame 110 of refrigerator main body 100 has disaster prevention unit housing section 900 between the lowermost storage chamber (e.g., main freezer 125) of the plurality of storage chambers 120 and floor F where refrigerator 1 is installed. The disaster prevention unit housing section 900 includes, for example, a preliminary power supply housing chamber PS for housing the preliminary power supply device 300 and an illumination device housing chamber LS for housing the illumination device 800.

The heat insulating frame 110 has a heat insulating partition wall 910 (see fig. 32) between the storage room at the lowermost layer (for example, the main freezer 125) and the disaster prevention unit storage unit 900 (the auxiliary power supply storage room PS and the lighting device storage room LS). The partition wall 910 includes a heat insulator 110 c. The partition 910 may also include a vacuum heat insulator.

In the present embodiment, the auxiliary power supply device 300 is formed in a flat shape substantially parallel to the floor surface F on which the refrigerator 1 is installed. For example, the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320 are each formed in a flat shape substantially parallel to the floor surface F. For example, the 1 st preliminary power supply device 310 and the 2 nd preliminary power supply device 320 are formed to have substantially the same thickness. The auxiliary power supply device 300 (1 st and 2 nd auxiliary power supply devices 310 and 320) is housed in the auxiliary power supply housing chamber PS and is positioned between the storage chamber at the lowermost layer (for example, the main freezer 125) and the floor surface F. Reserve power supply device 300 can be taken out toward the front of refrigerator 1 from between the storage room of the lowermost layer (for example, main freezer 125) and floor F.

As in embodiment 1, the 1 st auxiliary power supply device 310 is an auxiliary power supply device that remains integrally with the refrigerator main body 100 at the time of power failure and supplies power to the refrigerator main body 100. The 1 st preliminary power supply device 310 is detached from the refrigerator main body 100 when replaced due to aging.

Similarly to embodiment 1, the 2 nd auxiliary power supply device 320 is an auxiliary power supply device that can be separated from the refrigerator main body 100 and transported to a desired location as a portable power supply when power fails. The 2 nd auxiliary power supply device 320 is positioned in front of at least a part of the 1 st auxiliary power supply device 310, and can be taken out toward the front of the refrigerator 1 without interfering with the 1 st auxiliary power supply device 310.

In the present embodiment, the 1 st auxiliary power supply device 310 can be taken out from the auxiliary power supply storage chamber PS toward the front of the refrigerator 1. For example, the 1 st preliminary power supply device 310 has a1 st part 921 and a2 nd part 922. The 1 st part 921 is located behind the 2 nd preliminary power supply device 320. On the other hand, the 2 nd part 922 does not overlap with the 2 nd preliminary power supply apparatus 320 in the front-rear direction of the refrigerator 1. In the present embodiment, the front end portion of the 2 nd part 922 is disposed at substantially the same position as the front end portion of the 2 nd auxiliary power supply device 320 in the front-rear direction of the refrigerator 1. The 2 nd part 922 has a handle 930, for example. The handle 930 is a portion that the user holds when the 1 st auxiliary power supply device 310 is taken out from the refrigerator main body 100. According to this configuration, the 1 st auxiliary power supply apparatus 310 is easily detached from the refrigerator main body 100 when replaced due to aging.

In the present embodiment, the refrigerator 1 further includes a decorative cover 940 detachably attached to the refrigerator main body 100. The decorative cover 940 is disposed in front of the auxiliary power supply 300 and the lighting apparatus 800, and shields the auxiliary power supply 300 and the lighting apparatus 800 from the outside of the refrigerator 1. When the decorative cover 940 is detached from the refrigerator main body 100, the auxiliary power supply device 300 and the lighting device 800 are exposed to the outside of the refrigerator 1 toward the front of the refrigerator 1. In the present embodiment, when the decorative cover 940 is detached from the refrigerator main body 100, the handles 324 and 930 of the auxiliary power supply device 300 and the handle 806 of the illumination device 800 are exposed to the outside of the refrigerator 1 toward the front of the refrigerator 1.

Fig. 32 is a sectional view of the refrigerator 1 of embodiment 4 taken along the line F32-F32. In the present embodiment, the disaster prevention unit housing section 900 includes, for example, the support section 401, the buffer member 240, and the support surface forming member 250. The support portion 401 supports the auxiliary power supply device 300 from below. The buffer member 240 is positioned between the support portion 401 and the auxiliary power supply device 300. The support surface forming member 250 is positioned between the buffer member 240 and the auxiliary power supply device 300. However, when the vibration resistance of the preliminary power supply device 300 is relatively high, the buffer member 240 and/or the support surface forming member 250 may be omitted.

With this configuration, electricity can be secured in the event of a disaster. In the present embodiment, the heavy-weight auxiliary power supply device 300 is disposed at the lowest position of the refrigerator main body 100. This can improve the stability of the refrigerator 1 against earthquakes and the like. Further, if the auxiliary power supply device 300 is disposed at the lowermost portion of the refrigerator main body 100, the auxiliary power supply device 300 can be easily detached from the refrigerator 1, as compared with a case where the auxiliary power supply device 300 is disposed above the refrigerator main body 100. This makes it possible to more smoothly remove the 1 st auxiliary power supply device 310 when it is replaced due to aging and the 2 nd auxiliary power supply device 320 when a disaster occurs.

(embodiment 5)

Next, a refrigerator 1 according to embodiment 5 will be described. The present embodiment is different from embodiment 4 in that the disaster prevention unit 200 is disposed on the side of the refrigerator main body 100. The configuration other than the configuration described below is the same as that of embodiment 4.

Fig. 33 is a perspective view showing the refrigerator 1 of embodiment 5. In the present embodiment, the housing 210 of the disaster prevention unit 200 is disposed on the side of the refrigerator main body 100 (on the right side in the drawing, but may be on the left side). In the present modification, the housing 210, the auxiliary power supply device 300, and the lighting device 800 are disposed vertically along the right sidewall 114 (or the left sidewall 113) of the refrigerator main body 100. The opening 210a of the housing 210 opens upward. The auxiliary power supply 300 and the illumination apparatus 800 are removed upward from the housing 210.

With this configuration, electricity can be secured in the event of a disaster. In the present embodiment, the heavy-weight auxiliary power supply 300 is not disposed at a high position of the refrigerator main body 100. This can improve the stability of the refrigerator 1 against earthquakes and the like. Further, if the auxiliary power supply device 300 is disposed on the side of the refrigerator main body 100, the auxiliary power supply device 300 can be easily detached from the refrigerator 1, as compared with the case where the auxiliary power supply device 300 is disposed above the refrigerator main body 100. This makes it possible to more smoothly remove the 1 st auxiliary power supply device 310 when it is replaced due to aging and the 2 nd auxiliary power supply device 320 when a disaster occurs.

(embodiment 6)

Next, a refrigerator 1 according to embodiment 6 will be described. The present embodiment is different from embodiment 2 in that a disaster prevention unit housing portion 200Z is provided inside the heat insulating housing 110. The configuration other than the configuration described below is the same as that of embodiment 2.

[1. integral constitution of refrigerator ]

Fig. 34 is a front view showing the refrigerator 1 of the present embodiment. The refrigerator 1 includes, for example, a refrigerator main body 100 and a disaster prevention unit housing portion 200Z (see fig. 35). The disaster prevention unit housing section 200Z is an example of a "housing section".

[2. constitution of refrigerator Main body ]

First, the structure of the refrigerator main body 100 will be explained.

The refrigerator main body 100 includes, for example, a heat insulating housing 110 (see fig. 35), a plurality of doors 130, a cooling unit 140 (see fig. 35), a display device 150, an operation unit 160, a wireless communication unit 170, a power supply circuit unit 180, an acceleration sensor AS, and a control unit 190. The control unit 190 collectively controls the operations of the cooling unit 140, the display device 150, the operation unit 160, the wireless communication unit 170, the power supply circuit unit 180, and the disaster prevention unit housing unit 200Z.

Fig. 35 is a sectional view of the refrigerator 1 shown in fig. 34 taken along the line F35-F35. Duct 116 for guiding cold air cooled by refrigerator 141 is provided inside refrigerator compartment 121. Duct 116 extends substantially vertically along rear wall 115 of heat insulating housing 110, and a flow path through which cold air cooled by refrigerating room cooler 141 flows is formed between duct 116 and rear wall 115. Duct 116 has a plurality of cool air blowing ports 116a for supplying cool air flowing through the flow path to a plurality of height areas in refrigerating room 121. The cold air flowing through the flow path is blown into refrigerating room 121 through cold air blowing port 116 a. The plurality of cool air blowing openings 116a are arranged at a plurality of heights in the refrigerating compartment 121.

Fig. 36 is a block diagram showing a connection relationship of power lines of the refrigerator 1. The power supply circuit unit 180 converts ac power supplied from the commercial power supply P into dc power having a voltage suitable for each device included in the refrigerator 1, and supplies the converted dc power to each device. For example, the power supply circuit unit 180 supplies the dc power obtained by the conversion to the cooling unit 140, the display device 150, the operation unit 160, and the like.

[3. constitution of disaster prevention Unit accommodation portion ]

Next, the configuration of the disaster prevention unit housing portion 200Z will be described.

As shown in fig. 35, the disaster prevention unit housing portion 200Z is provided inside the heat insulation frame 110. For example, the disaster prevention unit housing portion 200Z is provided at the uppermost portion inside the heat insulation frame 110. That is, the disaster prevention unit housing 200Z is provided between the uppermost storage chamber (for example, the refrigerating chamber 121) among the plurality of storage chambers 120 and the top wall 111 of the heat insulating frame 110. The disaster prevention unit housing portion 200Z of the present embodiment is an example of the "1 st housing portion".

A housing chamber (housing space) S for housing devices and/or supplies and the like useful in the event of a disaster is formed inside the disaster prevention unit housing portion 200Z. In other words, the disaster prevention unit housing portion 200Z defines the housing chamber S. The housing chamber S is a space where the cold air is not supplied without the cold air blowing port 116 a. In the present specification, "not supplied with cold air" means that cold air is not supplied actively (intentionally), and includes a case where unintended cold air flows in through a gap between an opening 200a of a disaster prevention unit housing portion 200Z described later and a front cover 220.

[3.1 outline constitution of disaster prevention Unit housing part 200Z ]

The disaster prevention unit storage unit 200Z has a configuration of a storage chamber S in which the disaster prevention unit storage unit 200Z is at least partially partitioned (for example, partitioned from the storage chamber 120) inside the heat insulating frame 110. In the present embodiment, the disaster prevention unit housing portion 200Z includes, for example, a partition wall 210Z and a front cover 220 as a configuration of a housing chamber S that partitions the disaster prevention unit housing portion 200Z inside the heat insulating housing 110.

Here, the front cover 220 will be explained first.

The disaster prevention unit housing portion 200Z has an opening 200a that opens toward the front of the refrigerator 1. The housing chamber S is exposed to the outside of the disaster prevention unit housing portion 200Z through the opening 200 a. The user can put in and take out articles into and from the storage compartment S through the opening 200 a. In the present embodiment, the opening 200a is located behind the upper end portions of the refrigerating compartment doors 131A, 131B, and faces the refrigerating compartment doors 131A, 131B.

The front cover 220 is positioned in front of the opening 200a of the disaster prevention unit housing portion 200Z. The front cover 220 is pivotally supported by a hinge hg (see fig. 39), for example, and closes an opening 200a of the disaster prevention unit housing portion 200Z so as to be openable and closable.

The front cover 220 is formed of, for example, a transparent member. In this case, a display screen D4 of the auxiliary power supply device 300 described later can be visually confirmed through the front cover 220. Further, at least a part of the front cover 220 may be formed of a transparent or translucent member, and the display area D3 may be formed by the display device BD provided behind the front cover 220 (see fig. 39). In this case, characters and/or graphics projected from the display device BD disposed behind the front cover 220 to the front cover 220 are displayed in the display area D3.

Next, the partition wall 210Z will be explained.

The partition wall 210Z is provided inside the heat insulating frame 110. The partition wall 210Z is provided between the uppermost storage compartment (for example, the refrigerating compartment 121) of the plurality of storage compartments 120 and the storage compartment S of the disaster prevention unit storage unit 200Z. From another viewpoint, the partition wall 210Z is provided at a position above the uppermost cold air blowing port 116a among the plurality of cold air blowing ports 116a, and is disposed at a height position between the uppermost cold air blowing port 116a and the top wall 111 of the heat insulating frame 110.

The partition wall 210Z extends in a substantially horizontal direction in the lateral width direction of the refrigerator 1 and the front-rear direction of the refrigerator 1. Partition wall 210Z is provided across substantially the entire width of heat insulating frame 110 in the lateral width direction of refrigerator 1, and is connected to left sidewall 113 and right sidewall 114. Thus, the storage chamber S of the disaster prevention unit storage unit 200Z is defined inside the heat-insulating housing 110 between the uppermost storage chamber 120 (e.g., the refrigerating chamber 121) and the top wall 111 of the heat-insulating housing 110. In other words, the partition wall 210Z forms a bottom wall of the disaster prevention unit housing portion 200Z. Further, partition wall 210Z may be provided integrally with heat insulation frame 110, or may be provided independently of heat insulation frame 110.

In the present embodiment, the partition wall 210Z is provided integrally with the heat insulating frame 110. The partition wall 210Z has, for example, an inner box upper portion 210aZ, an inner box lower portion 210bZ, and a heat insulating material 210cZ filled between the inner box upper portion 210aZ and the inner box lower portion 210bZ, and has heat insulation properties. The heat insulator 210cZ is a foamed heat insulator such as foamed urethane, for example.

In the present embodiment, the thickness (e.g., the minimum thickness) of the partition wall 210Z is thicker than the thickness (e.g., the minimum thickness) of the top wall 111 of the heat insulating frame 110. For example, the thickness (e.g., minimum thickness) of the heat insulator 210cZ of the partition wall 210Z is thicker than the thickness (e.g., minimum thickness) of the heat insulator 110c of the top wall 111 of the heat insulating frame 110.

Fig. 37 is a sectional view of the refrigerator 1 shown in fig. 35 taken along the line F37-F37. The partition wall 210Z includes, for example, a Vacuum Insulation Panel (VIP) 211 a. The vacuum heat insulator 211a is formed in a plate shape substantially parallel to the lower surface of the partition wall 210Z, and is disposed between the inner box lower portion 210bZ and the heat insulator 210 cZ. If the vacuum heat insulator 211a is provided, the cool air circulating in the storage room 120 is less likely to be heated by the temperature of the disaster prevention unit housing portion 200Z. For example, if the vacuum heat insulating material 211a is provided, when the auxiliary power supply device 300 of the disaster prevention unit housing portion 200Z described later generates heat, the heat of the auxiliary power supply device 300 can be suppressed from being transferred to the cold air in the storage chamber 120. However, all or a part of the partition wall 210Z does not necessarily have to have heat insulation properties, and may be formed of a material having no heat insulation properties.

Further, the partition wall 210Z may also have a reinforcing member 211 b. The reinforcing member 211b is, for example, a member having higher rigidity than one or more of the inner box upper portion 210aZ, the inner box lower portion 210bZ, and the heat insulating material 210cZ, and is, for example, a metal member. The reinforcing member 211b is provided substantially parallel to the upper surface of the partition wall 210Z, for example, and is disposed between the inner box upper portion 210aZ and the heat insulator 210 cZ. The reinforcing member 211b extends over at least a part of the left sidewall 113 and over at least a part of the right sidewall 114. When the reinforcing member 211b is provided, the load of the disaster prevention unit housing portion 200Z can be easily supported by the left side wall 113 and the right side wall 114. However, the reinforcing member 211b is not an essential component, and may not be provided if sufficient rigidity can be ensured.

Next, the components disposed in the housing chamber S of the disaster prevention unit housing portion 200Z will be described. In the present embodiment, the housing chamber S includes a reserve power supply housing chamber (reserve power supply housing space) PS for housing the reserve power supply device 300 and a disaster prevention article housing chamber (disaster prevention article housing space) GS for housing the disaster prevention article 700. A partition wall 217 is provided between the auxiliary power supply storage chamber PS and the disaster prevention product storage chamber GS. The auxiliary power supply accommodation chamber PS and the disaster prevention product accommodation chamber GS are partitioned by a partition wall 217. The partition wall 217 is made of, for example, synthetic resin and has electrical insulation. Accordingly, even if the auxiliary power supply device 300 is damaged by, for example, shaking of an earthquake, electrical safety inside the disaster prevention product storage room GS can be ensured more reliably.

[3.2 Standby Power supply accommodation Chamber and Standby Power supply device ]

The preliminary power supply housing chamber PS is provided with a preliminary power supply device 300, a buffer member 240, a support surface forming member 250, a leakage receiving portion 260, and a preliminary power supply fixing portion 270.

[3.2.1 Overall configuration of Standby Power supply device ]

Next, the auxiliary power supply device 300 will be explained.

The auxiliary power supply device 300 is a device that supplies power instead of the commercial power supply P when a power failure occurs (when a disaster occurs). The auxiliary power supply device 300 is electrically connected to the refrigerator main body 100 via a power line 404 (see fig. 36) in the refrigerator main body 100. The auxiliary power supply 300 is electrically connected to the commercial power supply P via a power line 404 in the refrigerator main body 100, a power cable 185 of the refrigerator main body 100, and the like (see fig. 36).

In the present embodiment, at least a part of the auxiliary power supply device 300 can be used as a portable power supply separately from the refrigerator main body 100. In the present specification, "usable as being separable from refrigerator main body 100" and "separable from refrigerator main body 100" mean that the refrigerator main body can be separated from heat insulating frame body 110 and transported to a place different from the place where refrigerator main body 100 is installed. The term "portable power source" broadly means a portable power source, and includes a relatively small-sized portable battery and the like.

Other details of the auxiliary power supply 300 are the same as those of the auxiliary power supply 300 according to embodiment 1. That is, the auxiliary power supply apparatus main body 300U of the auxiliary power supply apparatus 300 includes the 1 st auxiliary power supply apparatus 310 and the 2 nd auxiliary power supply apparatus 320.

[3.2.2 No. 1 Standby Power supply device ]

The 1 st auxiliary power supply 310 is retained integrally with the refrigerator main body 100 (in the storage chamber S of the disaster prevention unit storage portion 200Z) at the time of power failure, and supplies power necessary for maintaining the cooling function of the refrigerator 1, such as power for driving the compressor 145 and the cooling unit 140, to the refrigerator main body 100. The 1 st auxiliary power supply device 310 includes, for example, a1 st auxiliary power supply case 311, a battery cell 312, a1 st terminal unit 313, a2 nd terminal unit 314, a voltage sensor VS1 (see fig. 36), and a current sensor IS1 (see fig. 36).

The 1 st terminal portion 313 is provided at the 1 st end portion 311a of the 1 st auxiliary power supply case 311. The 1 st terminal portion 313 is a terminal portion for connecting the 1 st auxiliary power supply device 310 and the main body connector 330. The 1 st auxiliary power supply device 310 is connected to the main body connector 330, and is electrically connected to the refrigerator main body 100 through the main body connector 330 and the power supply circuit unit 350. Thereby, the battery unit 312 of the 1 st auxiliary power supply 310 is supplied with power from the refrigerator main body 100 and can be charged.

The 2 nd terminal portion 314 is provided at the 2 nd end portion 311b of the 1 st auxiliary power supply case 311. The 2 nd terminal unit 314 is a terminal unit for connecting the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320. The terminal unit 314 includes, for example, a power terminal PT through which a current for supplying power flows and a signal terminal ST through which a signal flows, and can transmit and receive power and a signal. The 1 ST terminal 313 and terminal portions 316, 323, 331, and 803 described below also have a power terminal PT and a signal terminal ST, respectively, in the same manner as the terminal portion 117, and can transmit and receive power and signals.

[3.2.3 2 nd preparatory power supply device ]

The 2 nd auxiliary power supply device 320 is an auxiliary power supply device that can be separated from the refrigerator main body 100 as a portable power supply and transported to a desired place for use in the event of a power failure or a disaster requiring evacuation. That is, the 2 nd auxiliary power supply device 320 can be taken out of the housing chamber S of the disaster prevention unit housing portion 200Z and used as an auxiliary power supply device in a state of being transported to a living room, a bedroom, an evacuation room, or the like. The 2 nd auxiliary power supply device 320 is used for charging various electronic devices (a smartphone, a tablet terminal, a notebook computer, a radio, a portable television, and the like) of the user, for example.

In addition, the 2 nd auxiliary power supply device 320 can supply power to the refrigerator main body 100 together with the 1 st auxiliary power supply device 310 when not used separately from the refrigerator main body 100. That is, for example, when the sustainable operation time of the refrigerator main body 100 at the time of power failure is to be increased, the 2 nd auxiliary power supply device 320 is retained integrally with the refrigerator main body 100 together with the 1 st auxiliary power supply device 310 (retained in the storage chamber S of the disaster prevention unit storage portion 200Z), and thus can supply the refrigerator main body 100 with the 1 st auxiliary power supply device 310 with electric power necessary for maintaining the cooling function of the refrigerator 1.

Specifically, the 2 nd auxiliary power supply device 320 includes, for example, a2 nd auxiliary power supply case 321, a battery unit 322, a terminal portion 323, a handle 324, a display device 325, a plurality of connectors 326, a power supply circuit portion 327, a voltage sensor VS2 (see fig. 36), a current sensor IS2 (see fig. 36), and a2 nd auxiliary power supply control portion 328.

The terminal portion 323 is provided at the 1 st end portion 321a of the 2 nd auxiliary power supply case 321. The terminal portion 323 is a terminal portion for connecting the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320, and is detachably connected to the 2 nd terminal portion 314 of the 1 st auxiliary power supply device 310. The 2 nd auxiliary power supply device 320 is connected to the 1 st auxiliary power supply device 310, and is electrically connected to the refrigerator main body 100 through the 1 st auxiliary power supply device 310, the main body connector 330, and the power supply circuit unit 350. Thereby, the battery unit 322 of the 2 nd auxiliary power supply device 320 is supplied with power from the refrigerator main body 100 and can be charged. The battery cell 322 of the 2 nd auxiliary power supply device 320 is electrically connected in parallel to the battery cell 312 of the 1 st auxiliary power supply device 310, for example. Instead of this, the battery cell 322 of the 2 nd auxiliary power supply device 320 and the battery cell 312 of the 1 st auxiliary power supply device 310 may be electrically connected in series.

The handle 324 is provided at the 2 nd end 321b of the 2 nd auxiliary power supply casing 321. The handle 324 is a portion that a user holds when the 2 nd auxiliary power supply device 320 is taken out from the inside of the housing chamber S of the disaster prevention unit housing portion 200Z and when the 2 nd auxiliary power supply device 320 is carried. In a state where the 2 nd auxiliary power supply device 320 is housed in the housing chamber S of the disaster prevention unit housing portion 200Z, the handle 324 is located at a position closest to the opening 200a of the disaster prevention unit housing portion 200Z in the auxiliary power supply device main body 300U. When the front cover 220 of the disaster prevention unit housing portion 200Z is opened, the handle 324 is exposed to the outside of the disaster prevention unit housing portion 200Z toward the front of the refrigerator 1 through the opening 200a of the disaster prevention unit housing portion 200Z.

The 2 nd auxiliary power supply control unit 328 can communicate with the auxiliary power supply overall control unit 360 via the terminal units 323, 313, and 314 and the main body connector 330, for example. The 2 nd auxiliary power supply control unit 328 can communicate with the control unit 190 of the refrigerator main body 100 via the terminal units 323, 313, and 314 and the main body connector 330, for example. However, instead of the above, the 2 nd auxiliary power supply control unit 328 may communicate with the auxiliary power supply overall control unit 360 and the control unit 190 of the refrigerator main body 100 by Bluetooth (registered trademark) or other wireless communication.

Here, in refrigerator main body 100, widths WA and WB of left and right refrigerator doors 131A and 131B are different, and a boundary between left and right refrigerator doors 131A and 131B is located at a position shifted to the left side with respect to a center in a lateral width direction of refrigerator main body 100. As a result, an impact applied to the disaster prevention unit housing section 200Z when the left and right refrigerator doors 131A and 131B are closed is more easily transmitted to the left region than to the right region in the disaster prevention unit housing section 200Z. Therefore, in the present embodiment, the power supply circuit portion 327 and the 2 nd auxiliary power supply control portion 328 of the 2 nd auxiliary power supply device 320 are disposed in the 2 nd auxiliary power supply casing 321 so as to be shifted to the right side with respect to the center of the 2 nd auxiliary power supply casing 321. Thus, the impact applied to the disaster prevention unit housing portion 200Z when the refrigerator doors 131A and 131B are closed is not easily transmitted to the power circuit portion 327 and the 2 nd auxiliary power control portion 328.

[3.2.4 arrangement of the 1 st auxiliary power supply device and the 2 nd auxiliary power supply device ]

Fig. 38 is a cross-sectional view of the disaster prevention unit housing 200Z shown in fig. 37, taken along line F38-F38. Fig. 39 is a sectional view of the disaster prevention unit housing portion 200Z shown in fig. 37, taken along line F39-F39.

In the present embodiment, the 2 nd auxiliary power supply device 320 is disposed in front of the 1 st auxiliary power supply device 310 inside the housing chamber S of the disaster prevention unit housing portion 200Z, and is located closer to the opening 200a of the disaster prevention unit housing portion 200Z than the 1 st auxiliary power supply device 310. The 2 nd auxiliary power supply unit 320 can be removed from the inside of the storage chamber S toward the front of the storage chamber S (i.e., toward the front of the refrigerator 1) without interfering with the 1 st auxiliary power supply unit 310.

From another point of view, the 1 st auxiliary power supply device 310 is larger than the 2 nd auxiliary power supply device 320 and is heavier than the 2 nd auxiliary power supply device 320. The 1 st auxiliary power supply device 310 is disposed behind the 2 nd auxiliary power supply device 320 in the housing chamber S of the disaster prevention unit housing unit 200Z. This facilitates the center of gravity of the auxiliary power supply main body 300U to be located rearward.

In the present embodiment, the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320 are arranged at substantially the same height from each other and arranged in the front-rear direction of the refrigerator 1. This can lower the center of gravity of the auxiliary power supply main body 300U as compared with the case where one of the 1 st auxiliary power supply 310 and the 2 nd auxiliary power supply 320 is disposed at a higher position. In addition, when the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320 are disposed in the vertical direction, the 1 st auxiliary power supply device 310 is disposed below the 2 nd auxiliary power supply device 320 in the housing chamber S of the disaster prevention unit housing portion 200Z. This can lower the center of gravity of the auxiliary power supply main body 300U.

[3.2.5 other constitution of the preliminary power supply device ]

Next, the auxiliary power supply overall control unit 360 will be explained.

The entire auxiliary power supply control unit 360 is realized by, for example, one or more control boards, and is disposed in the auxiliary power supply accommodation chamber PS. The power supply circuit unit 350 and the auxiliary power supply overall control unit 360 may be realized by one substrate. The auxiliary power supply overall control unit 360 controls the entire auxiliary power supply device 300. For example, the auxiliary power supply overall control unit 360 controls the operation of the power supply circuit unit 350. The auxiliary power supply overall control unit 360 can communicate with the control unit 190 via a communication line provided between the control unit 190 and the refrigerator main body 100, for example. Instead of this, the auxiliary power supply overall control unit 360 may communicate with the control unit 190 of the refrigerator main body 100 by Bluetooth or other wireless communication. The function of the auxiliary power supply overall control unit 360 will be described in detail later.

The power circuit unit 350 and the entire auxiliary power supply control unit 360 are disposed in the housing chamber S so as to be shifted to the right with respect to the center of the housing chamber S. Thus, an impact applied to the disaster prevention unit housing portion 200Z when the refrigerator doors 131A and 131B are closed is not easily transmitted to the power circuit portion 350 and the auxiliary power supply overall control portion 360.

[3.2.6 center of gravity position of backup power supply device and disaster prevention unit ]

Next, the center of gravity G3 of the auxiliary power supply 300 will be described with reference to fig. 35. In a state where all of the plurality of doors 130 of the refrigerator main body 100 are in the fully opened position, the center of gravity position G3 of the preliminary power supply device 300 is located rearward with respect to the center of gravity position G1 of the refrigerator main body 100. According to this configuration, even when the refrigerator 1 shakes due to an earthquake, the refrigerator 1 provided with the disaster prevention unit housing portion 200Z is less likely to fall forward.

In the present embodiment, even in a state where all of the plurality of doors 103 of the refrigerator main body 100 are in the fully closed position, the center of gravity position G3 of the auxiliary power supply device 300 is located rearward with respect to the center of gravity position G1 of the refrigerator main body 100. With this configuration, even when the refrigerator 1 shakes due to an earthquake, the stability of the refrigerator 1 is increased, and the refrigerator 1 is less likely to fall forward.

From another point of view, as shown in fig. 38, the center position C3 of the auxiliary power supply 300 in the front-rear direction dimension (for example, the center position of the auxiliary power supply main body 300U in the front-rear direction dimension) is located rearward of the center position C1 of the refrigerator main body 100 in the front-rear direction dimension. From another different point of view, the distance L3a in the front-rear direction between the rear end of the auxiliary power supply device 300 (e.g., the rear end of the auxiliary power supply device main body 300U) and the rear end of the refrigerator main body 100 is smaller than the distance L3b in the front-rear direction between the front end of the auxiliary power supply device 300 (e.g., the front end of the auxiliary power supply device main body 300U) and the front end of the refrigerator main body 100.

Fig. 40 is a side view of the refrigerator 1 which is inclined forward by a predetermined angle α (for example, 8 degrees) with respect to a horizontal plane. When all of the doors 130 of the refrigerator main body 100 are in the fully open position and the refrigerator 1 is tilted forward by a predetermined angle α (for example, 8 degrees), the center of gravity position G3 of the auxiliary power supply device 300 is located rearward with respect to the center of gravity position G1 of the refrigerator main body 100. With this configuration, even when the refrigerator 1 shakes relatively largely due to an earthquake, the refrigerator 1 is less likely to fall forward.

In the present embodiment, even in a state where all of the doors 130 of the refrigerator main body 100 are at the fully closed position and the refrigerator 1 is tilted forward by the predetermined angle α (for example, 8 degrees), the center of gravity position G3 of the auxiliary power supply device 300 is located rearward with respect to the center of gravity position G1 of the refrigerator main body 100. With this configuration, the stability of the refrigerator 1 is increased, and the refrigerator 1 is less likely to fall forward.

From another point of view, even in a state where refrigerator 1 is tilted forward by a predetermined angle α (for example, 8 degrees), center of gravity G3 of auxiliary power supply 300 is located rearward with respect to front leg 118 of refrigerator main body 100. With this configuration, the weight of the disaster prevention unit housing portion 200Z acts in a direction to restore the inclination of the refrigerator 1. This makes the refrigerator 1 less likely to fall forward.

Next, another configuration of the disaster prevention unit housing portion 200Z will be described.

[3.3 cushioning Member and bearing surface Forming Member ]

The cushioning member 240 and the bearing surface forming member 250 will be described with reference to fig. 37.

In the present embodiment, a buffer member 240 and a support surface forming member 250 are provided between the partition wall 210Z of the disaster prevention unit housing unit 200Z and the auxiliary power supply device 300.

The buffer member 240 is disposed between the partition wall 210Z of the disaster prevention unit housing portion 200Z and the auxiliary power supply main body 300U. The buffer member 240 is formed of an elastic body such as rubber or a spring, and is elastically deformable. The auxiliary power supply device main body 300U is supported by the partition wall 210Z via the buffer member 240. By providing the buffer member 240, it is possible to suppress the vibration of the refrigerator main body 100 (for example, the vibration of the compressor 145 of the refrigerator main body 100) from being transmitted to the auxiliary power supply apparatus main body 300U.

In the present embodiment, the buffer member 240 is provided in a pair corresponding to the left and right ends of the auxiliary power supply 300, and forms a pair of support portions for supporting the left and right ends of the auxiliary power supply 300. The pair of buffer members 240 are separated from each other in the lateral width direction of the refrigerator 1. The pair of buffer members 240 is provided with a space. Thus, a gap S1 that allows expansion of the auxiliary power supply device 300 during aging (expansion of the battery cells 312 and 322 described later) is formed between the auxiliary power supply device 300 and the partition wall 210Z.

The support surface forming member 250 is disposed between the buffer member 240 and the auxiliary power supply main body 300U. The bearing surface forming member 250 is formed of a member having a smaller friction coefficient than the buffer member 240. The supporting surface forming member 250 is, for example, a metal plate, and is bonded to the entire upper surface of the cushioning member 240. The auxiliary power supply device main body 300U (the 1 st and 2 nd auxiliary power supply devices 310 and 320) is slid on the support surface forming member 250 in a substantially horizontal direction, thereby being inserted into and taken out of the housing chamber S. This enables smooth removal of the 2 nd auxiliary power supply device 320 when a disaster occurs and removal of the 1 st auxiliary power supply device 310 when replacement is performed due to aging.

[3.4 receiving part for leakage ]

Next, the leakage receiving portion 260 will be described with reference to fig. 37.

In the present embodiment, a leakage receiving portion 260 is provided below the auxiliary power supply device 300. The leakage receiving unit 260 is disposed below the auxiliary power supply device main body 300U in the auxiliary power supply housing chamber PS, for example. If the battery cells 312 and 322 are damaged by shaking due to an earthquake or the like and the liquid leaks, the leaked liquid receiving portion 260 receives and accumulates the liquid. In the present embodiment, the leakage receiving portion 260 is provided between the pair of buffer members 240 that support the preliminary power supply device 300. The leakage liquid receiving portion 260 is, for example, an oil pan, but is not limited thereto. For example, the leaked liquid receiver 260 may be a rib 265 (see fig. 39) or the like provided at the distal end of the housing chamber S to prevent the leaked liquid from flowing out of the disaster prevention unit housing portion 200Z through the opening 200a of the disaster prevention unit housing portion 200Z.

[3.5 disaster prevention Commodity storage Chamber and disaster prevention article ]

Next, the disaster prevention product storage room GS will be described with reference to fig. 38.

The disaster prevention product storage chamber GS is disposed on the left of the auxiliary power supply storage chamber PS. Thus, the preliminary power supply housing chamber PS is disposed offset to the right side with respect to the center in the lateral width direction of the housing chamber S (opposite to the offset side with respect to the center in the lateral width direction of the refrigerator main body 100 with respect to the boundary between the left and right refrigerating chamber doors 131A and 131B). Thus, an impact applied to the disaster prevention unit housing portion 200Z when the refrigerator doors 131A and 131B are closed is not easily transmitted to the auxiliary power supply device 300.

Disaster prevention products (disaster prevention tools) 700 are housed in the disaster prevention product housing room GS.

With the above configuration, user convenience can be improved. That is, in the present embodiment, the refrigerator 1 includes the disaster prevention unit housing portion 200Z that is provided inside the heat insulating housing 110 and can house the auxiliary power supply device 300 and the disaster prevention article 700. With this configuration, it is possible to secure electricity and food in the event of a disaster by using the space in the heat insulating housing 110.

In the present embodiment, the heat insulating frame 110 includes a plurality of storage compartments 120. The disaster prevention unit housing 200Z is provided between the uppermost storage chamber (for example, the refrigerating chamber 121) of the plurality of storage chambers 120 and the top wall 111 of the heat insulating frame 110. With this configuration, the disaster prevention unit housing unit 200Z can be provided at the uppermost portion in the heat insulating frame 110, which is likely to become a dead space. This can suppress a decrease in the internal volume of the space portion with a high frequency of use in the refrigerator 1, and can secure electricity and food in the event of a disaster.

In the present embodiment, the auxiliary power supply device 300 includes a1 st auxiliary power supply device 310 that supplies power to the refrigerator main body 100 when power fails. With this configuration, even when a power failure occurs, the refrigerator main body 100 can be continuously operated, and food items for several days until recovery can be easily secured. In the present embodiment, the auxiliary power supply device 300 includes a2 nd auxiliary power supply device 320 that can be used as a portable power supply. With this configuration, the 2 nd auxiliary power supply device 320 can be used in a desired place in a home, an evacuation facility, or the like.

In the present embodiment, the 2 nd auxiliary power supply device 320 is connected to the 1 st auxiliary power supply device 310, and is supplied with power from the refrigerator main body 100 via the 1 st auxiliary power supply device 310, whereby charging is possible. With this configuration, the 2 nd auxiliary power supply device 320 can be easily disposed in front of the 1 st auxiliary power supply device 310, as compared with a case where the main body connector 330 is provided with an electrical connection portion for the 2 nd auxiliary power supply device 320. When the 2 nd auxiliary power supply device 320 is disposed in front of the 1 st auxiliary power supply device 310, the ease of taking out the 2 nd auxiliary power supply device 320 is improved.

In the present embodiment, the 1 st auxiliary power supply device 310 is heavier than the 2 nd auxiliary power supply device 320 and is disposed behind the 2 nd auxiliary power supply device 320 or below the 2 nd auxiliary power supply device 320. With this configuration, the center of gravity of the disaster prevention unit housing portion 200Z is easily located rearward or downward, and the refrigerator 1 including the disaster prevention unit housing portion 200Z is easily stabilized.

(7 th embodiment)

Next, a refrigerator 1 according to embodiment 7 will be described. The present embodiment is different from embodiment 6 in that the disaster prevention unit housing portion 200Z includes a lighting device housing chamber LS capable of housing the lighting device 800. The configuration other than the configuration described below is the same as that of embodiment 6.

Fig. 42 is a sectional view showing the disaster prevention unit housing section 200Z according to embodiment 7. In the present embodiment, the housing chamber S of the disaster prevention unit housing portion 200Z includes an illumination device housing chamber (illumination device housing space) LS housing the illumination device 800, in addition to the preliminary power supply housing chamber PS and the disaster prevention product housing chamber GS.

In the present embodiment, the lighting device housing chamber LS is disposed on the right side of the auxiliary power supply housing chamber PS. The lighting device housing chamber LS and the auxiliary power supply housing chamber PS are disposed at substantially the same height. With this configuration, the heavy auxiliary power supply device 300 can be easily disposed near the center of the housing chamber S in the lateral width direction, compared to the case where the lighting device housing chamber LS is disposed between the disaster prevention product housing chamber GS and the auxiliary power supply housing chamber PS. This can improve the stability of the refrigerator 1 including the disaster prevention unit housing portion 200Z in the lateral direction.

A partition wall 218 is provided between the preliminary power supply housing chamber PS and the lighting device housing chamber LS so as to be detachable from the housing chamber S. The partition wall 218 is made of synthetic resin and has electrical insulation. If the partition wall 218 is provided between the auxiliary power supply housing chamber PS and the lighting device housing chamber LS, electrical safety inside the lighting device housing chamber LS can be ensured more reliably even if the auxiliary power supply 300 is broken by shaking of an earthquake, for example. Further, if the partition wall 218 is detachable from the housing chamber S, even when the 1 st auxiliary power supply device 310 is larger than the 2 nd auxiliary power supply device 320, the 1 st auxiliary power supply device 310 can be removed to the front of the housing chamber S.

In the present embodiment, the lighting device 800 can be used as a portable lamp separately from the refrigerator main body 100 (can be taken out of the housing chamber S of the disaster prevention unit housing portion 200Z and used). That is, the lighting device 800 can be carried to a place different from the place where the refrigerator main body 100 is installed and used.

For example, the lighting device 800 includes a lighting device case 801, a battery 802 (see fig. 43), a terminal unit 803, a1 st lamp unit 804, a2 nd lamp unit 805, a handle 806, and a controller 807, as in embodiment 3.

In the present embodiment, the handle 806 is provided at the 2 nd end 801b of the lighting device case 801. The handle 806 is a portion that a user holds when taking out the lighting apparatus 800 from the housing chamber S of the disaster prevention unit housing portion 200Z and when carrying the lighting apparatus 800. In a state where the lighting apparatus 800 is housed in the housing chamber S of the disaster prevention unit housing portion 200Z, the handle 806 is positioned closest to the opening 200a of the disaster prevention unit housing portion 200Z in the lighting apparatus 800. When the front cover 220 of the disaster prevention unit housing portion 200Z is opened, the handle 806 is exposed to the outside of the housing chamber S toward the front of the housing chamber S through the opening 200a of the disaster prevention unit housing portion 200Z.

Fig. 43 is a sectional view of the disaster prevention unit receiving part 200Z shown in fig. 42 taken along the line F43-F43. In the present embodiment, the width W1 in the lateral direction of the 1 st auxiliary power supply device 310 is larger than the width W2 in the lateral direction of the 2 nd auxiliary power supply device 320. The 1 st preliminary power supply device 310 has a1 st area 310a and a2 nd area 310 b. The 1 st area 310a faces the 2 nd preliminary power supply device 320 in the front-rear direction of the refrigerator 1. The 1 st area 310a has a2 nd terminal portion 314 connected to the 2 nd auxiliary power supply 320. On the other hand, the 2 nd area 310b faces the lighting device 800 in the front-rear direction of the refrigerator 1. The 2 nd region 310b has a3 rd terminal portion 316 connected to the lighting device 800.

In the present embodiment, at least a part of the 1 st lamp unit 804 of the lighting device 800 is located forward of the front end of the auxiliary power supply 300 (for example, the 2 nd end 321b of the 2 nd auxiliary power supply 320). Thus, the 1 st lamp unit 804 can illuminate the handle 324, the display screen D4, the connector 326, and the like of the 2 nd auxiliary power supply device 320. For example, at least a part of the 1 st lamp unit 804 is located forward of the front end of the partition wall 218, and the partition wall 218 is located between the lighting device housing chamber LS and the auxiliary power supply housing chamber PS. Thus, the 1 st lamp unit 804 can illuminate the handle 324, the display screen D4, the connector 326, and the like of the 2 nd auxiliary power supply device 320 without being obstructed by the partition wall 218.

At least a part of the 1 st lamp unit 804 is located forward of the front end of the partition 217, and the partition 217 is located between the disaster prevention product storage chamber GS and the auxiliary power supply storage chamber PS. Thus, the 1 st lamp unit 804 can illuminate the front end portion of the disaster prevention article storage room GS without being obstructed by the partition 217.

In the present embodiment, when the lighting device 800 is used as a portable lamp and the remaining capacity of the battery 802 is reduced and then electrically connected to the 1 st auxiliary power supply device 310, the charge/discharge control unit 513 of the refrigerator main body 100 charges the battery 802 of the lighting device 800 with the electric power discharged from the battery cell 312 of the 1 st auxiliary power supply device 310.

With this configuration, it is possible to secure electric power, food, and lighting in the event of a disaster by using the space in the heat insulating housing 110. The configuration of the lighting device 800 is not limited to the above example. For example, lighting device 800 may include only one of lamp 1 and lamp 2, 804 and 805.

Next, several modifications of embodiment 7 will be described. In each modification, the configuration other than the configuration described below is the same as that of embodiment 7.

(modification 1)

Fig. 44 is a sectional view showing the disaster prevention unit housing section 200Z of the 1 st modification. In the present modification, the front cover 220 is formed of a translucent member. The "translucent member" may be transparent, translucent, or colored. For example, the front cover 220 is formed as a light guide plate. That is, the front cover 220 has a1 st surface 220a facing forward, a2 nd surface 220b located opposite to the 1 st surface 220a, and a light transmitting portion 220c located between the 1 st surface 220a and the 2 nd surface 220 b. The 2 nd surface 220b is provided with irregularities for diffusing light.

In the present modification, the front cover 220 of the disaster prevention unit housing portion 200Z has a notch C that avoids the lighting device 800. The front end of the illumination device 800 protrudes outside the housing chamber S. Lamp part 1 804 of lighting device 800 is disposed in cutout C of front cover 220 and is located on a side of a part of front cover 220. The lighting device 800, for example, emits light from the side of the front cover 220 toward the light-transmitting portion 220c of the front cover 220. The light incident on the light-transmitting portion 220c of the front cover 220 travels inside the front cover 220 and is diffused by the 2 nd surface 220 b. This makes the entire front cover 220 bright. With this configuration, the position of the disaster prevention unit housing unit 200Z can be more easily known at the time of power failure.

(modification 2)

Fig. 45 is a sectional view showing a refrigerator 1 according to modification 2. In this modification, the upper ends of the refrigerating chamber doors 131A and 131B are located at a position lower than the top wall 111 of the heat insulating frame 110, and the front cover 220 of the disaster prevention unit housing portion 200Z is exposed to the outside of the refrigerator main body 100. On the other hand, an airtight gasket PK is provided between the refrigerating compartment doors 131A, 131B and the partition wall 210Z. Between the refrigerating compartment doors 131A, 131B and the partition wall 210Z, a gasket PK is hermetically closed.

With this configuration, the user can take out the 2 nd auxiliary power supply device 320, the disaster prevention product 700, and the lighting device 800 stored in the storage chamber S of the disaster prevention unit storage unit 200Z by opening the front cover 220 of the disaster prevention unit storage unit 200Z without opening the refrigerating chamber doors 131A and 131B when a disaster occurs. Further, according to the configuration of the present modification, the space for cold air circulation can be limited to a smaller size than in embodiments 6 and 7, and thus the cooling efficiency of refrigerating room 121 can be improved.

(embodiment 8)

Next, a refrigerator 1 according to embodiment 8 will be described. The present embodiment is different from embodiment 6 in that a disaster prevention unit housing portion 200Z is provided in a recessed portion R on the upper surface of the top wall 111 of the heat insulating housing 110. The configuration other than the configuration described below is the same as that of embodiment 6.

Fig. 46 is a sectional view showing the refrigerator 1 according to embodiment 8. In the present embodiment, the disaster prevention unit housing portion 200Z is provided in a recessed portion R formed in the upper surface of the top wall 111 of the heat insulation frame 110. The disaster prevention unit housing portion 200Z of the present embodiment is an example of the "2 nd housing portion".

In detail, the top wall 111 has a1 st portion 901 and a2 nd portion 902 located rearward with respect to the 1 st portion 901. Portion 2 902 is located at a lower elevation relative to portion 1 901. A step 903 rising in a substantially vertical direction exists between the 1 st portion 901 and the 2 nd portion 902, for example. A recess R is formed in the top wall 111 by the step 903. An example of a height H of step 903 is greater than a thickness (e.g., minimum thickness) T1Z of portion 1 901 or a thickness (e.g., minimum thickness) T2Z of portion 2 902.

The recess R is provided, for example, up to a position adjacent to the rear wall 115 of the heat insulating frame 110. The center of the recess R in the front-rear direction dimension is located rearward with respect to the center of the top wall 111 in the front-rear direction dimension.

In the present embodiment, the housing chamber S of the disaster prevention unit housing portion 200Z includes a reserve power supply housing chamber PS housing the reserve power supply device 300. The disaster prevention unit storage portion 200Z has a structure of a storage chamber S that at least partially partitions the disaster prevention unit storage portion 200Z from an external space of the refrigerator 1, for example. In the present embodiment, the disaster prevention unit housing portion 200Z has a cover 920 that covers the upper side of the housing chamber S. The cover 920 is detachably attached to the top wall 111 of the heat insulating frame 110.

Fig. 47 is a plan view showing the refrigerator 1 of the present embodiment. Fig. 47 shows a state in which the cover 920 is removed. In the present embodiment, the housing chamber S of the disaster prevention unit housing portion 200Z is provided over substantially the entire width of the heat insulation frame 110. For example, the width Wy in the lateral width direction of the housing chamber S of the disaster prevention unit housing portion 200Z is larger than the width Wx in the front-rear direction of the housing chamber S. From another viewpoint, the width Wy in the lateral width direction of the housing chamber S of the disaster prevention unit housing portion 200Z is larger than the width WB in the lateral width direction of the right refrigerating chamber door 131B (or the width WA in the lateral width direction of the left refrigerating chamber door 131A).

In the present embodiment, the auxiliary power supply device 300 includes a1 st auxiliary power supply device 310 and a2 nd auxiliary power supply device 320. For example, the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320 are arranged in the lateral width direction of the refrigerator 1. In the present embodiment, the main body connector 330 includes: a1 st terminal portion 331A to which the 1 st auxiliary power supply device 310 is detachably connected; and a2 nd terminal portion 331B to which the 2 nd auxiliary power supply device 320 is detachably connected. The 2 nd auxiliary power supply device 320 is connected to the 2 nd terminal portion 331B of the main body connector 330, and thereby can be electrically connected to the refrigerator main body 100 to be charged. In place of the above, the 2 nd auxiliary power supply device 320 may be connected to the 1 st auxiliary power supply device 310 and electrically connected to the main body connector 330 via the 1 st auxiliary power supply device 310, as in embodiment 6.

Fig. 48 is a sectional view of the disaster prevention unit receiving part 200Z shown in fig. 47 taken along the line F48-F48. In the present embodiment, the handle 324 is provided on the upper portion of the 2 nd auxiliary power supply casing 321. In a state where the 2 nd auxiliary power supply device 320 is housed in the housing chamber S of the disaster prevention unit housing portion 200Z, the handle 324 protrudes upward from the 2 nd auxiliary power supply housing 321. When the cover 920 of the disaster prevention unit housing portion 200Z is detached, the handle 324 is exposed to the outside of the disaster prevention unit housing portion 200Z.

With this configuration, user convenience can be improved. That is, in the present embodiment, the refrigerator 1 includes the disaster prevention unit housing portion 200Z provided in the recessed portion R formed in the upper surface of the top wall 111 of the heat insulating frame 110. With this configuration, it is possible to secure electricity in the event of a disaster by the upper end portion of the heat insulating frame 110 which is likely to become a dead space.

(embodiment 9)

Next, a refrigerator 1 according to embodiment 9 will be described. The present embodiment is different from embodiment 8 in that the housing chamber S of the disaster prevention unit housing portion 200Z includes a disaster prevention product housing chamber GS. The configuration other than the configuration described below is the same as that of embodiment 8.

In the present embodiment, the housing chamber S of the disaster prevention unit housing portion 200Z includes the disaster prevention product housing chamber GS in addition to the preliminary power supply housing chamber PS.

The disaster prevention product storage chamber GS is disposed on the left of the auxiliary power supply storage chamber PS. Thus, the auxiliary power source housing chamber PS is disposed offset to the right side with respect to the center of the housing chamber S in the lateral width direction (opposite side to the side where the boundary with the left and right refrigerating compartment doors 131A, 131B is offset with respect to the center of the refrigerator main body 100 in the lateral width direction). Thus, an impact applied to the disaster prevention unit housing portion 200Z when the refrigerator doors 131A and 131B are closed is not easily transmitted to the auxiliary power supply device 300.

Fig. 50 is a cross-sectional view of the disaster prevention unit housing 200Z shown in fig. 49 taken along line F50-F50. In the present embodiment, the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320 are disposed, for example, so as to overlap each other in the vertical direction. Specifically, the 1 st auxiliary power supply 310 is disposed below the 2 nd auxiliary power supply 320. With this configuration, the center of gravity of the disaster prevention unit housing portion 200Z is easily located downward, and the refrigerator 1 including the disaster prevention unit housing portion 200Z is easily stabilized.

(embodiment 10)

Next, a refrigerator 1 according to embodiment 10 will be described. The present embodiment is different from embodiment 9 in that the housing chamber S of the disaster prevention unit housing portion 200Z includes the lighting device housing chamber LS. The configuration other than the configuration described below is the same as that of embodiment 9.

In the present embodiment, the disaster prevention unit housing portion 200Z includes an illumination device housing chamber LS for housing the illumination device 800, in addition to the auxiliary power supply housing chamber PS and the disaster prevention product housing chamber GS.

In the present embodiment, the lighting device housing chamber LS is disposed on the right side of the auxiliary power supply housing chamber PS. The lighting device housing chamber LS and the auxiliary power supply housing chamber PS are arranged at substantially the same height. With this configuration, the heavy auxiliary power supply device 300 can be easily disposed near the center of the housing chamber S in the lateral width direction, as compared with the case where the lighting device housing chamber LS is disposed between the disaster prevention product housing chamber GS and the auxiliary power supply housing chamber PS. This can improve the stability of the refrigerator 1 including the disaster prevention unit housing portion 200Z in the lateral direction.

In the present embodiment, the main body connector 330 includes: a1 st terminal 331 to which the auxiliary power supply device 300 is detachably connected; and a2 nd terminal portion 332 to which the lighting device 800 is detachably connected. The lighting device 800 is connected to the 2 nd terminal portion 332 of the main body connector 330, and thereby can be electrically connected to the refrigerator main body 100 to be charged. In place of the above, the 2 nd auxiliary power supply device 320 may be connected to the 1 st auxiliary power supply device 310 and electrically connected to the main body connector 330 via the 1 st auxiliary power supply device 310, as in embodiment 6.

In the present embodiment, the handle 806 is provided at an upper portion of the lighting device case 801. In a state where the lighting apparatus 800 is housed in the housing chamber S of the disaster prevention unit housing portion 200Z, the handle 806 protrudes upward from the lighting apparatus housing 801. When the cover 920 of the disaster prevention unit housing portion 200Z is removed, the handle 806 is exposed to the outside of the disaster prevention unit housing portion 200Z.

(embodiment 11)

Next, a refrigerator 1 according to embodiment 11 will be described. In the present embodiment, the disaster prevention unit housing unit 200Z includes: a1 st accommodating part 200A provided inside the heat insulating frame 110; and a2 nd housing part 200B provided in the recess R of the top wall 111 of the heat insulating frame 110. The 1 st housing portion 200A has the same configuration as the disaster prevention unit housing portion 200Z according to embodiment 6. The 1 st storage unit 200A includes at least one of the auxiliary power supply storage chamber PS, the disaster prevention product storage chamber GS, and the lighting device storage chamber LS. On the other hand, the 2 nd housing portion 200B has the same configuration as the disaster prevention unit housing portion 200Z of embodiment 8. The 2 nd storage portion 200B includes at least one of the reserve power supply storage chamber PS, the disaster prevention product storage chamber GS, and the lighting device storage chamber LS.

With this configuration, user convenience can be improved as in embodiment 6 or 8.

The above description has been given of several embodiments and modifications, but the embodiments are not limited to the above examples. For example, the embodiments 1 to 11 and their modifications can be combined with each other.

For example, the auxiliary power supply device 300 is not limited to a device that is charged by being supplied with electric power from the commercial power supply P via the refrigerator main body 100, and may be charged by being supplied with electric power from the commercial power supply P without being passed through the refrigerator main body 100. In this case, the refrigerator main body 100 may be supplied with electric power from the commercial power supply P via the auxiliary power supply device 300.

From a certain viewpoint, the disaster prevention unit 200 does not necessarily need to include the auxiliary power supply 300, and may include only at least one disaster prevention product storage room for storing the disaster prevention product 700 or only the illumination device storage room for storing the illumination device 800. The lighting device 800 is not limited to a portable lighting device, and may be a lighting device fixed to the heat insulating frame 110.

The auxiliary power supply device 300 is not limited to the configuration including the 1 st auxiliary power supply device 310 and the 2 nd auxiliary power supply device 320. For example, the auxiliary power supply 300 may be constituted by only the 1 st auxiliary power supply 310 or may be constituted by only the 2 nd auxiliary power supply 320. In the above embodiment, the 2 nd auxiliary power supply device 320 is electrically connected to the refrigerator main body 100 via the 1 st auxiliary power supply device 310. Instead of this, the 2 nd auxiliary power supply device 320 may be directly connected to a terminal portion provided in the main body connector 330, and thereby electrically connected to the refrigerator main body 100 without passing through the 1 st auxiliary power supply device 310, and may be charged with the electric power supplied from the refrigerator main body 100.

The 2 nd auxiliary power supply device 320 may be electrically connected to the refrigerator main body 100 without the 1 st auxiliary power supply device 310, and may be directly connected to a terminal provided in the main body connector 330, so that it may be electrically connected to the refrigerator main body 100 without the 1 st auxiliary power supply device 310, and may be charged with electric power supplied from the refrigerator main body 100.

According to at least 1 embodiment described above, the refrigerator can improve user convenience by including the auxiliary power supply device that is electrically connected to the refrigerator main body, can be charged with or using a part of electric power supplied from an external power supply to the refrigerator main body, and at least a part of which can be used separately from the refrigerator main body as a portable power supply.

Several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
