Description

Technical Field

[0001] This invention relates to a storage device. Background Technology

[0002] Storage devices for the exchange of food and other stored items, installed in shops or outdoors, are now well known (see, for example, Patent Document 1).

[0003] The storage device of Patent Document 1 includes an inner door that closes the opening of the storage compartment, and an outer door that can be freely opened and closed from the outside of the inner door. The storage device of Patent Document 1 has an unlocking operation part, a spring, a first rotating member, and a second rotating member, forming a structure for locking and unlocking the outer door. When the outer door is locked, the unlocking operation part protrudes downward from the door lock device; when the outer door is unlocked, the unlocking operation part is embedded within the door lock device. The spring applies force to rotate the first rotating member forward. The first rotating member is configured such that when the inner door rotates in the closing direction, the first rotating member is pressed by the inner door and rotates backward. The second rotating member is configured such that when the first rotating member rotates backward, the second rotating member rotates backward, thereby allowing the unlocking operation part to protrude downward from the door lock device.

[0004] In the storage device of Patent Document 1, a mechanism is provided that allows the outer door to be unlocked even when power to the door lock device is unavailable due to a power outage or other reasons. This mechanism includes a rod-shaped operating member located behind the unlocking operation section. The operating member extends vertically from the mechanical chamber located at the bottom of the storage device, spanning the lower and middle refrigerated storage compartments. The operating member includes a pressing member that abuts against the lower surface of the unlocking operation section of the door lock device or the lower surface of the second rotating member.

[0005] In the storage device of Patent Document 1 as described above, when the outer door is locked, the outer door is rotated rearward to contact the inner door, and then the inner door is rotated by rotating the outer door. When the first rotating member rotates rearward due to the rearward rotation of the inner door, the second rotating member also rotates rearward as the first rotating member rotates, thereby allowing the unlocking operation part to protrude downward from the door lock device. Moreover, by the unlocking operation part protruding downward from the door lock device, the pin member of the door lock device rotates and engages with the pin receiving member of the outer door, thereby locking the outer door.

[0006] On the other hand, when unlocking the outer door while the door lock device is powered on, the control box is operated. When an electrical signal based on the operation of the control box is input to the door lock device, the engagement between the pin member of the door lock device and the pin receiving member of the outer door is released, thereby unlocking the outer door.

[0007] Additionally, for example, when unlocking the outer door when power is not supplied to the door lock device due to a power outage, the locking device of the machine room is unlocked to open the machine room door, and the operating member is operated up and down from inside the machine room. By operating the operating member, the pressing member is pressed against the lower surface of the unlocking operating part or the lower surface of the second rotating member, and the unlocking operating part is pushed upwards and submerged within the door lock device. When the unlocking operating part is submerged within the door lock device, the engagement between the pin member of the door lock device and the pin receiving member of the outer door is released, thereby unlocking the outer door.

[0092] [Structure of the storage device]

[0093] First, let me explain the structure of the storage device. Figure 1 This is a front view showing the storage unit with its inner and outer doors closed. Figure 2 It is a 3D view showing the storage device with its inner and outer doors open. Figure 3 It is a cross-sectional perspective view showing the internal structure of the storage device. Figure 4 It is a cross-sectional view showing the internal structure of the storage device when viewed from the front. Figure 5 This is a partial longitudinal sectional view showing the storage device with its inner and outer doors closed. Figure 6 This is a partial longitudinal section view showing the unlocking mechanism of the storage device. Figure 7 This is the front view showing the storage unit with its outer door open. Figure 8 This is a 3D view of the storage device with the outer door open, viewed from the inner surface of the outer door. Figure 9 This is a 3D diagram of an electronic lock. Figure 10 This is a side view showing the locked state of the outer door with an electronic lock. Figure 11 This is the main view showing the state where the unlocking mechanism's operating components are not activated.

[0094] Figures 1-6 The storage device 1 shown is installed in a shop or outdoors for the exchange of fresh food, frozen food, and other stored items. The storage device 1 stores the stored items in frozen (e.g., approximately -20°C), refrigerated (e.g., above 1°C and below 5°C), or room temperature (e.g., approximately 10°C) conditions. The storage device 1 includes: a storage unit 10, a temperature control unit 100, and a control unit (not shown).

[0095] The storage unit 10 has five storage sections 20 and an unlocking mechanism 50. In this embodiment, a structure with five storage sections 20 is illustrated, but the number of storage sections 20 is not limited to five; it can be four or less, or six or more.

[0096] The storage unit 10 also includes: five inner boxes 21, five inner doors 22, one outer box 23, five outer doors 24, and five electronic locks 40.

[0097] The inner casing 21 has a heat transfer structure. The inner casing 21 is formed as a square box with an inner opening 211 on the front side. The object to be stored is housed inside the inner casing 21. For example... Figure 3 and Figure 4As shown, a plurality of back slits 212 are provided on the back of the inner casing 21, which are used to allow cooling air from the temperature control unit 100 to enter the interior of the inner casing 21. A plurality of side slits 213 are provided on the left and right sides of the inner casing 21, which are used to exhaust air from the interior of the inner casing 21 to the outside.

[0098] The inner door 22 is configured to close the inner opening 211 of the inner box 21. For example... Figure 7 As shown, the inner door 22 is rotatably connected to the front right end of the inner box 21 via, for example, a spring-loaded hinge 221 provided on one side edge of the inner door 22. The spring-loaded hinge 221 functions as an inner door force-applying part that applies force to the inner door 22 in the direction of closing the inner door 22. The spring-loaded hinge 221 is an example of a closed state holding part that keeps the inner door 22 closed. A frame-shaped sealing gasket 222 for sealing the inner box 21 is provided on the inner surface of the inner door 22. The sealing gasket 222 has a heat-insulating structure. An operating groove 223 for inserting a finger when the user (employee or customer) opens the inner door 22 is provided on the outer surface of the inner door 22.

[0099] like Figures 1-6 As shown, the outer casing 23 is formed into a square box shape with an opening on the front side. The outer casing 23 includes a heat-insulating frame 231, an outer fitting part 232, and an outer opening forming part 233.

[0100] The heat-insulating housing 231 has a heat-insulating structure. For example... Figure 3 and Figure 4As shown, the heat insulation housing 231 is formed into a square box shape with five openings on the front and one opening on the upper surface. Inside the heat insulation housing 231, five inner boxes 21 are arranged side by side. The five inner boxes 21 are arranged such that, when viewed from the front side of the storage unit 10, the inner openings 211 overlap with the openings on the front side of the heat insulation housing 231. A back flow channel F1 is provided between the back of the heat insulation housing 231 and the back of the inner boxes 21. Side flow channels F2 are provided between the left and right sides of the heat insulation housing 231 and the left and right sides of the inner boxes 21. Above the uppermost inner box 21 inside the heat insulation housing 231, a cooling air outlet 101 constituting the temperature control unit 100 is arranged. The cooling air outlet 101 is arranged to protrude from the opening on the upper surface of the heat insulation housing 231. As indicated by arrow Y1, the cooling air supplied from the cooling air outlet 101 flows through the rear flow channel F1 and enters the interior of the inner casing 21 through the rear gap 212. Air that has undergone heat exchange inside the inner casing 21, as indicated by arrow Y2, flows out through the side gap 213, flows through the side flow channel F2, and enters the cooling air outlet 101. The air entering the cooling air outlet 101 is cooled by the cooling air outlet 101 and is then supplied as cooling air to the rear flow channel F1. In other words, the interior of the inner casing 21 is cooled through the circulation of cooling air inside the heat insulation shell 231.

[0101] The outer casing 232 includes a right side panel 234, a left side panel 235, a lower front panel 236, and an upper front panel 237. The right side panel 234 and the left side panel 235 are arranged to cover the left and right side portions of the heat insulation housing 231, respectively. The lower front panel 236 and the upper front panel 237 are positioned at a predetermined distance from the lower and upper portions of the front of the heat insulation housing 231, respectively, and have the function of making the lower and upper portions invisible from the front of the storage unit 10. Furthermore, the outer casing 232 may further include a back panel that covers the back of the heat insulation housing 231. In this case, the outer casing 232 may also be a box-shaped structure formed by integrating the back panel, right side panel 234, left side panel 235, lower front panel 236, and upper front panel 237.

[0102] The outer opening forming portion 233 is configured to divide the opening portion into five outer opening portions 230, which are defined by the front edge of the right side plate portion 234 and the left side plate portion 235, the upper edge of the front lower plate portion 236, and the lower edge of the front upper plate portion 237. The outer opening forming portion 233 is formed in a square cylindrical shape. The outer opening forming portion 233 is formed such that when viewed from the front side of the storage unit 10, the outer opening portion 230 is located outside the inner opening portion 211. With this structure, the stored object can be stored inside the inner box 21 via the outer opening portion 230 and the inner opening portion 211.

[0103] The outer door 24 is configured to close the outer opening 230 of the outer casing 23. When the outer door 24 is closed, as... Figure 5 As shown, a space is formed between the outer door 24 and the inner door 22, defined by the inner door 22, the outer opening forming portion 233, the portion of the heat insulation housing 231 connecting the inner box 21 and the outer opening portion 230, and the outer door 24. This space functions as an air insulation layer K that meets specified heat insulation performance. The air insulation layer K has the following function: when the temperature around the housing 1 rises, it suppresses heat transfer from the housing 1 to the inner box 21. The outer door 24 is as follows... Figure 8 As shown, for example, the outer door 24 is rotatably connected to the right side of the outer opening forming portion 233 via a hinge 241 provided on one edge of the outer door 24. On the rotating front end side of the inner surface of the outer door 24, a blocking part 25 is provided to prevent the outer door 24 from closing when the inner door 22 is not closed.

[0104] Each electronic lock 40 is controlled by a control unit (not shown), which locks and unlocks each outer door 24 respectively. Figure 9 and Figure 10 As shown, the electronic lock 40 includes a housing 41, a locking / unlocking mechanism 42, and an electrical drive unit 43.

[0105] The box body 41 is provided, for example, on the left side of the outer opening forming portion 233. A front opening is provided on the outer door 24 side (front side) of the box body 41. A cutout 411 is provided on the front side of the right side of the box body 41.

[0106] The locking and unlocking mechanism 42 includes: an unlocking rod 44, a rotating member 45, a rotating force-applying part (not shown), and a striking bolt 46.

[0107] The unlocking lever 44 is located on the inner box 21 side (rear side) inside the box body 41. One end of the unlocking lever 44 along its length (hereinafter referred to as the "rotation base end side") is rotatably mounted on a first rotation shaft 412 mounted on the box body 41. The other end of the unlocking lever 44 along its length (hereinafter referred to as the "rotation front end side") is provided such that it protrudes from the upper surface of the box body 41 toward the outside of the box body 41. A lever protrusion (not shown) protruding toward the front of the box body 41 is provided on the rotation base end side of the unlocking lever 44. A lever recess (not shown) recessed toward the rear is provided below the lever protrusion on the unlocking lever 44.

[0108] The rotating member 45 is positioned further forward than the unlocking lever 44. Furthermore, the rotating member 45 is rotatably mounted on a second rotating shaft 413 provided on the housing 41. The rotating member 45 includes a latch portion 451, an open state holding portion 452, and a rotating protrusion (not shown). The latch portion 451 extends downward from the front side of the housing 41. The open state holding portion 452 extends downward from a position further rearward than the latch portion 451. The rotating protrusion is positioned approximately perpendicular to the extending directions of the latch portion 451 and the open state holding portion 452, and extends in a direction approaching the unlocking lever 44. The rotating protrusion is shaped such that, when the rotating member 45 rotates, its front end contacts the upper surface of the lever protrusion of the unlocking lever 44, or its front end is located within the recess of the lever recess of the unlocking lever 44.

[0109] The rotating force-applying part applies force to the unlocking lever 44, causing the rotating front end of the unlocking lever 44 to rotate forward. The rotating force-applying part applies force to the rotating member 45, causing the latch 451 and the open state holding part 452 to rotate upward, and the rotating protrusion to rotate downward.

[0110] A striker 46 is provided on the edge side of the inner surface of the outer door 24, that is, on the rotating front end side of the outer door 24. The striker 46 is formed into a plate shape extending in a direction perpendicular to the inner surface of the outer door 24. On the front end side of the striker 46, an upper locking hole 461 is provided for the latch 451 to engage with. The upper locking hole 461 is an example of an engaging part.

[0111] The electric drive unit 43, controlled by the control unit, applies force to the unlocking lever 44 in the opposite direction to the force applied by the rotational force application unit. That is, the electric drive unit 43 presses the unlocking lever 44, causing the rotating tip side of the unlocking lever 44 to rotate rearward. The electric drive unit 43 presses the unlocking lever 44 by moving the rod-shaped member according to an electrical signal from the control unit.

[0112] The component provided on the left side of the outer opening forming portion 233 in the locking / unlocking mechanism 42 is as follows: Figure 7 The cover is as shown. The cover 47 has a through hole 471 for inserting the bolt 46.

[0113] Here, a storage unit 20 consists of a housing 20A, a door 20B, and an electronic lock 40. The housing 20A comprises an inner box 21, an outer opening forming part 233, and a portion of the heat-insulating shell 231 that accommodates the inner box 21. The door 20B consists of an inner door 22 and an outer door 24.

[0114] The unlocking mechanism 50 can be used to unlock the outer door 24 in situations where the electric drive unit 43 cannot be used to unlock it, such as during a power outage or when the control unit malfunctions. Figure 6 , Figures 9-11 As shown, the unlocking mechanism 50 includes an operating component 51 and a motion transmission part 52.

[0115] like Figure 1 As shown, the operating member 51 is provided at the lower end of the outer casing 23 in a manner that exposes to the outside, specifically, it is provided in the front lower plate portion 236. The operating member 51 is composed of a cylindrical lock that can only be operated using a special key, and is provided in a manner that exposes the keyhole 511 from the front (front lower plate portion 236) of the outer casing 23.

[0116] like Figure 6 As shown, the motion transmission unit 52 includes: an unlocking cam 53, a rod support member 54, an unlocking rod 55, five lever operating members 56, and five pressing members 57. The rod support member 54, the unlocking rod 55, the lever operating members 56, and the pressing members 57 are located on the left side of the outer opening forming part 233 and are covered by a cover 47.

[0117] like Figure 6 and Figure 11 As shown, the unlocking cam 53 is arranged to protrude to the left from the rear side of the operating member 51. The unlocking cam 53 is arranged to rotate in the same direction as the operating member 51 in conjunction with the rotation of the cylinder constituting the operating member 51. A through hole 531 in the front-rear direction is provided on the rotating front end side of the unlocking cam 53.

[0118] like Figure 6 and Figure 10 As shown, the rod support member 54 is positioned further rearward and higher than the housing 41 of the uppermost electronic lock 40. A support hole (not shown) extending vertically through the rod support member 54 is provided.

[0119] like Figure 6 and Figure 11 As shown, the lower end of the unlocking rod 55 is bent forward. The forward-extending portion of the lower end of the unlocking rod 55 is inserted from the rear into the insertion hole 531 of the unlocking cam 53. Figure 6 and Figure 10 As shown, the upper end of the unlocking rod 55 is inserted into the support hole of the rod support member 54 in the vertical direction. With this structure, the unlocking rod 55 moves up and down as the unlocking cam 53 rotates.

[0120] like Figure 9 and Figure 10As shown, five lever operating members 56 are rotatably mounted on the first rotation axis 412 of the housing 41. A lever pressing portion 561 extending laterally is provided in a portion of the lever operating member 56 located above the housing 41. The lever pressing portion 561 is located further forward than the portion protruding from the housing 41 of the unlocking lever 44. A pressed portion 562 extending laterally is provided in a portion of the lever operating member 56 located further rearward than the housing 41. The pressed portion 562 is located further downward than the pressing member 57.

[0121] like Figure 6 , Figure 9 and Figure 10 As shown, five pressing members 57 are fixed to the unlocking rod 55, each located on the rear side of the respective housing 41. The pressing members 57 move downward as the unlocking rod 55 slides downward, pressing the pressed portion 562 of the rod operating member 56.

[0122] like Figures 1-6 As shown, the temperature control unit 100 is located on the upper part of the outer casing 23. The temperature control unit 100 is controlled by a control unit (not shown) to enable all the storage compartments 20 to be in one of the following states: frozen, refrigerated, or at room temperature.

[0123] The control unit includes a control unit housing. A user-operated touch panel is located on the front of the control unit housing. An antenna is mounted on the top surface of the control unit housing. A computer that integrates the control housing 1 is located inside the control unit housing. A router is also located inside the control unit housing, which relays communication when the computer communicates with external devices. Additionally, an adapter for relaying the connection between the antenna and the router is located in the power distribution room of the control unit housing.

[0124] The computer connects to the touch panel and executes user instructions input via the touch panel. The computer communicates wirelessly with the outside via a router and antenna. Furthermore, a through-hole (not shown) is formed on the front of the top surface of the control unit housing, allowing the power distribution room to communicate with the outside and through which the signal cable connected to the antenna passes.

[0125] (The operation of the storage device)

[0126] Next, the operation of storage device 1 will be explained. Figure 12 This is the main view showing the state of the unlocking mechanism's operating components when they are activated. Figure 13 This is a side view showing the unlocked state of the outer door when the unlocking mechanism is used.

[0127] <Electronic lock locking status>

[0128] First, let's explain the locked state of the electronic lock 40. When the external door 24 is locked by the electronic lock 40, the front end of the rotating protrusion of the rotating member 45 contacts the upper surface of the rod protrusion of the unlocking lever 44, as shown below. Figure 10 As shown, with the latch portion 451, which is embedded in the upper locking hole portion 461 of the bolt 46, extending directly downward, the rotation of the rotating member 45 is restricted.

[0129] At this time, the lever operating member 56 of the unlocking mechanism 50 maintains the state in which the lever pressing part 561 does not resist the force applied by the rotating force applying part and presses the unlocking lever 44 backward. Figure 11 As shown, the operating component 51 of the unlocking mechanism 50 keeps the keyhole 511 extending in the vertical direction.

[0130] Unlocking action of electronic lock using control unit>

[0131] Next, the unlocking operation of the electronic lock 40 using the control unit will be explained. When the user performs an unlocking operation using the control unit's touch panel or other operating parts, the control unit outputs an electrical signal to the electrical drive unit 43 of the electronic lock 40. The electrical drive unit 43 moves the rod-shaped member according to the electrical signal from the control unit, thereby pressing the unlocking lever 44 backward. When the unlocking lever 44 rotates backward, the protrusion of the unlocking lever 44 moves away from the rotating protrusion of the rotating member 45, thereby releasing the contact between the upper surface of the protrusion and the rotating protrusion. When the contact between the upper surface of the protrusion and the rotating protrusion is released, the rotating member 45 rotates forward by the force applied by the rotation force application part, and the rotation of the rotating member 45 is restricted when the front end of the rotating protrusion is located within the recess of the rod recess. When the front end of the rotating protrusion is located within the recess of the rod recess, the electrical drive unit 43 returns the rod-shaped member to its original position.

[0132] By rotating the rotating member 45 forward at this time, the latch 451 is rotated to expose the outside of the housing 41 (see reference). Figure 13 As the latch 451 rotates, the bolt 46 is pushed out to the outside of the housing 41, and the latch 451 disengages from the upper locking hole 461, unlocking and opening the outer door 24. Furthermore, by rotating the rotating member 45 forward, the open-state holding part 452 moves to a position exposed through the cutout 411 of the housing 41. Even if the opened outer door 24 rotates towards the closing direction, the rotation of the outer door 24 is restricted because the bolt 46 contacts the open-state holding part 452 exposed through the cutout 411. As a result, the outer door 24 remains open. Additionally, at this time, due to the force applied by the spring-loaded hinge 221, the inner door 22 remains closed regardless of whether the outer door 24 is open.

[0133] Unlocking Actions of Electronic Locks Using Unlocking Mechanisms

[0134] Next, the unlocking action of the electronic lock 40 using the unlocking mechanism 50 will be explained. In the event of a power outage or control unit malfunction, when the staff wants to unlock the outer door 24, they insert a key (not shown). Figure 11 The keyhole 511 of the operating member 51 in the state shown is turned to the left, thereby, as Figure 12 As shown, the unlocking cam 53 rotates downwards, causing the unlocking rod 55 to move downwards. As the unlocking rod 55 moves downwards, as... Figure 13 As shown, all the pressing members 57 press the lever pressing part 561, thereby rotating the lever operating member 56 rearward. When the lever operating member 56 rotates rearward, the lever pressing part 561 moves rearward and presses the unlocking lever 44 rearward. When the unlocking lever 44 rotates rearward, the locking and unlocking mechanism 42 of the electronic lock 40 operates in the same way as when the unlocking action is used with the control unit, unlocking the outer door 24. With the outer door 24 unlocked, the outer door 24 remains open due to the contact between the open state holding part 452 and the bolt 46, and the inner door 22 remains closed due to the force applied by the spring hinge 221.

[0135] [The Role and Effects of the Implementation Method]

[0136] The storage device 1 is equipped with an unlocking mechanism 50 for manually unlocking the outer door 24. Therefore, even when the electrical drive unit 43 is not activated due to a power outage, the outer door 24 can still be unlocked, improving the convenience of the storage device 1. Especially during a power outage, since the temperature control unit 100 is also not activated, the temperature of fresh and frozen foods stored therein may rise, potentially reducing their value. However, because the outer door 24 can be manually unlocked, the fresh and frozen foods can be immediately moved to other refrigerators or freezers. Furthermore, the operating member 51 constituting the unlocking mechanism 50 is positioned to protrude from the exterior of the outer casing 30. Therefore, unlike the storage device in Patent Document 1 described above, where the operating member 51 needs to be opened before operation, the outer door 24 can be unlocked quickly.

[0137] The operating element 51 is a cylindrical lock. Therefore, the outer door 24 cannot be opened without a special key, thus preventing the theft of stored items.

[0138] The unlocking mechanism 50 is configured to unlock all five outer doors 24 at the same time. Therefore, even if it is impossible to determine which of the five inner doors 21 contains the stored item, the inner door 21 containing the stored item can be easily and quickly identified by unlocking all five outer doors 24 at the same time.

[0139] If the outer door 24 is unlocked, the storage device 1 keeps the outer door 24 open via the open state holding part 452, and keeps the inner door 22 closed via the force applied by the spring-loaded hinge 221. Therefore, the user can easily determine that the outer door is unlocked. Furthermore, by keeping the inner door 22 closed, it is possible to prevent outside air from entering the inner compartment 21 and causing temperature changes in the stored items. Therefore, in the case of fresh or frozen foods, it is possible to prevent a decrease in the value of the goods due to temperature changes. Moreover, after unlocking the outer door 24, the user does not need to immediately remove the stored items from the inner compartment 21 to avoid temperature changes; they can remove the stored items at their own pace.

[0140] As a closing state holding part that keeps the inner door 22 closed, a spring-loaded hinge 221 is used, which has the function of freely connecting the inner door 22 to the inner box 21 and applying force to the inner door 22 in the direction of closing the inner door 22. Therefore, compared with the case of using multiple components that each have one of the above two functions, the number of parts can be reduced.

[0141] The electronic lock 40 has a latch 451 and an open state holding part 452 on its rotating member 45. The latch 451 has the function of locking and unlocking the outer door 24, and the open state holding part 452 has the function of keeping the outer door 24 open. Therefore, without the need for a mechanism that links the latch 451 and the open state holding part 452, the outer door 24 can be unlocked and the open state of the outer door 24 can be maintained simply by rotating the rotating member 45 once.

[0142] The storage device 1 has an air insulation layer K formed in front of the inner box 21. Therefore, even if the temperature around the storage device 1 rises, heat transfer from the storage device 1 to the inner box 21 can be suppressed. Therefore, even if the storage device 1 is installed outdoors, temperature changes of the stored object inside the inner box 21 can be suppressed.

[0143] [Variations on the implementation method]

[0144] Of course, the present invention is not limited to the embodiments described herein, and various modifications can be made without departing from its inventive concept.

[0145] Alternatively, instead of using a cylindrical lock as the operating element 51, a structure that can be operated by anyone without a special key can be used. In this case, it is preferable to place the operating element in a location that is difficult for customers to see, such as the lower end of the outer casing 30.

[0146] The storage device 1 can also be equipped with five unlocking mechanisms, each for unlocking an outer door 24.

[0147] As a closed-state retention part, a structure other than the spring-loaded hinge 221 can also be used, such as a structure that magnetically attaches the inner door 22 to the inner box 21. In this case, the inner door 22 can be rotatably connected to the inner box 21 using a hinge without a spring.

[0148] Alternatively, instead of providing an open state holding part 452 in the rotating member 45 of the electronic lock 40, the rod-shaped open state holding part is moved to protrude from the cutout 411 in conjunction with the forward rotation of the rotating member 45, and the outer door 24 is kept open by contact between the open state holding part and the bolt 46.

[0149] The storage device 1 may also include a temperature control unit for heating the stored object. The storage device 1 may also include a temperature control unit capable of individually controlling the temperature of each storage section 20. Alternatively, the storage device 1 may not include a temperature control unit 100.

[0150] In the storage device 1, the air insulation layer K may not be provided, and it may be configured like the storage device in Patent Document 1, such that when the inner door 22 and the outer door 24 are closed, the inner door 22 is close to the outer door 24.

[0151] The storage section 20 is composed of a so-called double-door structure with an inner door 22 and an outer door 24, but it can also be composed of a box and a door that closes the opening of the box.

[0152] The items stored in the storage device 1 can be any kind of storage item that can be stored in the storage device 1, excluding fresh food and frozen food, such as food, beverages, medicines, daily necessities, groceries, electronic equipment, books, etc.
