Description

TECHNICAL FIELD

[0001] The present application relates to a storage device. BACKGROUND

[0002] Now, a storage device for the handover of a storage object such as food, which is provided at a store or the like, is well known (for example, refer to Patent Literature 1).

[0003] The storage device of Patent Literature 1 has an inner door that closes an opening of a storage chamber, and an outer door that is opened and closed freely on the outside of the inner door. The storage device of Patent Literature 1 has an unlocking operation portion, a spring, a first rotation member, and a second rotation member as a structure that locks and unlocks the outer door. In a state where the outer door is locked, the unlocking operation portion protrudes downward from a door lock device; in a state where the outer door is unlocked, the unlocking operation portion is buried in the door lock device. The spring exerts a force in such a manner that the first rotation member rotates in the forward direction. The first rotation member is configured in such a manner that when the inner door turns in the closing direction, the first rotation member is pressed by the inner door and rotates in the rearward direction. The second rotation member is configured in such a manner that when the first rotation member rotates in the rearward direction, the second rotation member rotates in the rearward direction, thereby allowing the unlocking operation portion to protrude downward from the door lock device.

[0004] In the storage device of Patent Literature 1 as described above, when the outer door is locked, the outer door is turned in the rearward direction to contact the inner door, and further the inner door is turned by the outer door being turned. When the first rotation member rotates in the rearward direction due to the inner door rotating in the rearward direction, the second rotation member also rotates in the rearward direction along with the rotation of the first rotation member, thereby allowing the unlocking operation portion to protrude downward from the door lock device. Further, by the unlocking operation portion protruding downward from the door lock device, a pin member of the door lock device rotates to engage with a pin receiving member of the outer door, thereby locking the outer door.

[0005] If the outer door is locked, it becomes a state where there is almost no gap between the outer door and the inner door. The reason why there is almost no gap between the outer door and the inner door is that since there is no locking mechanism of the inner door, and the first rotation member is exerted with a force in the forward direction by the spring, if there is a large gap between the outer door and the inner door, the inner door would turn in the forward direction by the force of the spring with the aid of the first rotation member, thereby causing the inner door to open.

[0006] Further, if the outer door is locked, since there is no locking mechanism of the inner door, and there is almost no gap between the outer door and the inner door, the inner door, which is exerted with a force in the forward direction by the spring via the first rotation member, becomes a state where the opening of the storage chamber is closed in a state where the turning in the forward direction is restricted by the outer door.

[0009] Patent Literature 1: Japanese Patent Application Laid-Open No. 2003-97120 SUMMARY

[0010] PROBLEMS TO BE SOLVED BY THE INVENTION

[0011] However, in the storage device of Patent Literature 1, since there is almost no gap between the outer door and the inner door when the outer door is locked, heat around the storage device can be transferred into the storage chamber, and there is a problem that the temperature of the storage object in the storage chamber can be increased.

[0012] In the storage device of Patent Literature 1, in order to suppress the temperature increase of the storage object in the storage chamber, it can be considered that a large gap (space) is provided between the outer door and the inner door, and the space functions as an air insulation layer. However, if the space functioning as the air insulation layer is provided, the outer door cannot be closed while the outer door is in contact with the inner door, and the outer door cannot be locked while the outer door is in contact with the inner door. Therefore, it can be considered that a mechanism for locking the outer door when the inner door is closed is not provided, and a locking mechanism of the outer door which is not linked with the operation of the inner door is provided. However, in the case where such a locking mechanism of the outer door is provided, since a large space for forming the air insulation layer is present between the outer door and the inner door, the outer door is locked even in a state where the inner door is not closed, for example, when the storage object is interposed between the storage chamber and the inner door. Therefore, there is a problem that the user can close the outer door without noticing that the inner door is not closed even in the state where the inner door is not closed.

[0013] In addition, in the storage device of Patent Literature 1, when the engagement of the pin member with the pin receiving member is released by the rotation of the pin member, the outer door is unlocked, but at the time of the unlocking, since the pin receiving member is forced in the forward direction with the rotation of the pin member, the outer door is turned and automatically opened. However, when the outer door is opened, since the restriction of the outer door to the forward turning of the inner door is released, the inner door is turned by the spring force and automatically opened. Therefore, the outside air enters the storage chamber, and there is a problem that the temperature of the storage object can be changed.

[0014] An object of the present application is to provide a storage device which can suppress the transfer of heat around the storage device into an inner case, and can make a user easily recognize a state where an inner door is not closed.

[0015] Another object of the present application is to provide a storage device in which, in a state where an outer door is unlocked, a user can easily determine the unlocked outer door, and a temperature change in an inner case can be suppressed.

[0016] SOLUTION TO PROBLEM

[0017] The storage device of the present application includes: an inner case having an inner opening; an inner door closing the inner opening; an outer case having an outer opening and the inner case disposed inside; an outer door closing the outer opening; and a blocking prevention portion preventing the outer door from being closed in a state where the inner door is not closed.

[0018] The storage device of the present application includes: an inner case having an inner opening; an inner door closing the inner opening; an outer case having an outer opening and the inner case disposed inside; an outer door closing the outer opening; a locking and unlocking mechanism locking and unlocking the outer door; an open state maintaining portion maintaining a state where the outer door is open in a case where the outer door is unlocked; and a closed state maintaining portion maintaining a state where the inner door is closed in a case where the outer door is unlocked.

[0019] Effects of the Invention

[0020] According to the storage device of the present application, heat transfer from the surroundings of the storage device to the inner case can be suppressed, and a user can easily recognize that the inner door is not closed.

[0021] According to the storage device of the present application, in a case where the outer door is unlocked, a user can easily determine the unlocked outer door, and temperature change in the inner case can be suppressed. BRIEF DESCRIPTION OF DRAWINGS

[0101] Figures 1 to 6 The housing device 1 illustrated in the drawing is provided at a store or the like, and is used for the handover of a storage object such as a fresh food or a frozen food. The housing device 1 stores the storage object in a frozen state (for example, about -20°C), a refrigerated state (for example, 1°C or higher and 5°C or lower), or a normal temperature state (for example, about 10°C). The housing device 1 includes a housing unit 10, a temperature control unit 100, and a control unit not illustrated.

[0102] The housing unit 10 includes five storage sections 20 and an unlocking mechanism 50. In the present embodiment, a structure in which the housing unit 10 includes five storage sections 20 is exemplified, but the number of the storage sections 20 is not limited to five, and can be four or less or six or more.

[0103] The housing unit 10 further includes five inner boxes 21, five inner doors 22, one outer box 23, five outer doors 24, five occlusion prevention sections 25, and five electronic locks 40.

[0104] The inner box 21 has a heat transfer structure. The inner box 21 is formed in a square box shape having an inner opening section 211 on the front surface side. A storage object is stored in the inside of the inner box 21. As illustrated in Figure 3 and Figure 4 A plurality of back surface slits 212 for allowing cooling air from the temperature control unit 100 to enter the inside of the inner box 21 are provided on the back surface section of the inner box 21. A plurality of side surface slits 213 for discharging air in the inside of the inner box 21 to the outside are provided on the left side surface section and the right side surface section of the inner box 21.

[0105] The inner door 22 is configured to close the inner opening section 211 of the inner box 21. As illustrated in Figure 7As shown, the inner door 22 is rotatably connected to the right front end portion of the inner case 21 by a spring-attached hinge 221 provided, for example, at a rim portion on one side of the inner door 22. The spring-attached hinge 221 functions as an inner door force application portion that applies a force to the inner door 22 in a direction to close the inner door 22. The spring-attached hinge 221 is an example of a closed state retaining portion that retains the inner door 22 in a closed state. A frame-shaped gasket 222 for sealing the inner case 21 is provided on the inner surface of the inner door 22. The gasket 222 has a heat-insulating structure. An operation groove portion 223 for a finger of a user (a clerk or a customer) to insert when the user opens the inner door 22 is provided on the outer surface of the inner door 22.

[0106] As shown in FIG. 1, the outer case 23 is formed in a square box shape having an opening portion on the front surface side. The outer case 23 includes a heat-insulating housing 231, an outer cover portion 232, and an outer opening forming portion 233. Figures 1 to 6

[0107] As shown in FIG. 1, the outer case 23 is formed in a square box shape having an opening portion on the front surface side. The outer case 23 includes a heat-insulating housing 231, an outer cover portion 232, and an outer opening forming portion 233.

The outer case 23 includes a heat-insulating housing 231, an outer cover portion 232, and an outer opening forming portion 233.

[0108] ​​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.

[0109] 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.

[0110] 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.

[0111] The blocking prevention portion 25 has a base portion 251 and a rod-shaped blocking prevention member 252. The base portion 251 is provided at a position closer to the rotation front end side than the center in the left-right direction of the inner surface of the outer door 24 and closer to the rotation base end side of the outer door 24 than the striker 46 described later. The blocking prevention member 252 extends from the base portion 251 in a direction perpendicular to the inner surface of the outer door 24. The blocking prevention member 252 is provided in such a manner that, when an object to be accommodated or a foreign object is sandwiched between the inner case 21 and the inner door 22, the blocking prevention member 252 comes into contact with a position of the rotation front end side of the inner door 22 that is located below the operation groove portion 223, thereby preventing the outer door 24 from being closed. Further, the blocking prevention member 252 is provided such that, when no object to be accommodated or foreign object is sandwiched between the inner case 21 and the inner door 22 and both the inner door 22 and the outer door 24 are closed, a gap of several millimeters or so is present between the front end of the blocking prevention member 252 and the inner door 22.

[0112] Each electronic lock 40 is controlled by a control unit not shown and locks and unlocks each outer door 24. Each electronic lock 40 is configured in such a manner that it can lock and unlock the outer door 24 independently of the opening and closing operation of the inner door 22. As shown in FIG. 2, the electronic lock 40 is provided on the left side surface portion of the outer opening forming portion 233. The electronic lock 40 is provided on the outer door 24 side (front side) of the outer opening forming portion 233. The electronic lock 40 is provided on the right side surface portion of the outer opening forming portion 233.

The rotation protruding portion is provided so as to extend in a direction substantially perpendicular to the extending directions of the latch portion 451 and the open state retaining portion 452, and in a direction approaching the unlocking lever 44. The rotation protruding portion is formed in a shape such that, when the rotation member 45 is rotated, either a state in which a front end portion of the rotation protruding portion is in contact with an upper surface of the lever protruding portion of the unlocking lever 44, or a state in which the front end portion of the rotation protruding portion is positioned inside the recess of the lever recess portion of the unlocking lever 44, is achieved.

[0117] The rotation force applying portion applies a force to the unlocking lever 44 so as to rotate the rotation front end side of the unlocking lever 44 to the front side. The rotation force applying portion applies a force to the rotation member 45 so as to rotate the latch portion 451 and the open state retaining portion 452 upward, and to rotate the rotation protruding portion downward.

[0118] The latch bolt 46 is provided at the edge portion on the other side of the inner surface of the outer door 24, that is, the rotation front end side of the outer door 24. The latch bolt 46 is formed in a plate shape extending in a direction perpendicular to the inner surface of the outer door 24. At the front end side of the latch bolt 46, an upper lock hole portion 461 in which the latch portion 451 is fitted is provided. The upper lock hole portion 461 is an example of a fitting portion.

[0119] The electric drive portion 43 is controlled by the control unit to apply a force to the unlocking lever 44 in a direction opposite to the direction of the force applied by the rotation force applying portion. That is, the electric drive portion 43 presses the unlocking lever 44 so as to rotate the rotation front end side of the unlocking lever 44 to the rear side. The electric drive portion 43 presses the unlocking lever 44 using a rod-shaped member by moving the rod-shaped member in accordance with an electric signal from the control unit, for example.

[0120] The member provided at the left side surface portion of the outer opening forming portion 233 in the upper lock unlocking mechanism 42 is covered by a cover as shown in Figure 7 The cover 47 is provided with a through hole 471 in which the latch bolt 46 is inserted.

The temperature control unit 100 is controlled by a control unit (not shown) to unify all the storage compartments 20 into one of the following states: frozen, refrigerated, or room temperature.

[0131] The control unit has 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 compartment of the control unit housing.

[0132] 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 top surface of the control unit housing, allowing communication between the power distribution room and the outside, and facilitating the passage of the signal cable connected to the antenna.

[0133] (The operation of the storage device)

[0134] 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. Figure 14 It is a cross-sectional view showing the state where the inner door is not closed and the closing of the outer door is prevented.

[0135] <Electronic lock locking status>

[0136] First, the locked state of the electronic lock 40 will be described. When the outer door 24 is locked by the electronic lock 40, the front end portion of the rotation protruding portion of the rotation member 45 is in contact with the upper surface of the lever protruding portion of the unlocking lever 44, as shown in FIG. 6, and the latch portion 451 embedded in the locked hole portion 461 of the latch bolt 46 extends downward, and the rotation of the rotation member 45 is restricted. Further, as a mechanism for embedding the latch portion 451 in the locked hole portion 461, a mechanism in which a pressed portion that moves together with the latch portion 451 is provided inside the case body 41, and the latch portion 451 is moved to be embedded in the locked hole portion 461 by pressing the pressed portion with the latch bolt 46 inserted into the inside of the case body 41 can be used. In addition, as a mechanism for embedding the latch portion 451 in the locked hole portion 461, a mechanism in which the latch portion 451 is moved to be embedded in the locked hole portion 461 based on an electric signal output from the control unit can also be used. Figure 10 As shown in FIG. 6, the front end portion of the rotation protruding portion of the rotation member 45 is in contact with the upper surface of the lever protruding portion of the unlocking lever 44, and the latch portion 451 embedded in the locked hole portion 461 of the latch bolt 46 extends downward, and the rotation of the rotation member 45 is restricted. Further, as a mechanism for embedding the latch portion 451 in the locked hole portion 461, a mechanism in which a pressed portion that moves together with the latch portion 451 is provided inside the case body 41, and the latch portion 451 is moved to be embedded in the locked hole portion 461 by pressing the pressed portion with the latch bolt 46 inserted into the inside of the case body 41 can be used. In addition, as a mechanism for embedding the latch portion 451 in the locked hole portion 461, a mechanism in which the latch portion 451 is moved to be embedded in the locked hole portion 461 based on an electric signal output from the control unit can also be used.

[0137] At this time, the lever operating member 56 of the unlocking mechanism 50 maintains the state in which the lever pressing portion 561 does not press the unlocking lever 44 to the rear side against the urging force of the rotation urging portion. As shown in FIG. 6, the operating member 51 of the unlocking mechanism 50 maintains the state in which the keyhole 511 extends in the up-down direction. Figure 11 As shown in FIG. 6, the front end portion of the rotation protruding portion of the rotation member 45 is in contact with the upper surface of the lever protruding portion of the unlocking lever 44, and the latch portion 451 embedded in the locked hole portion 461 of the latch bolt 46 extends downward, and the rotation of the rotation member 45 is restricted. Further, as a mechanism for embedding the latch portion 451 in the locked hole portion 461, a mechanism in which a pressed portion that moves together with the latch portion 451 is provided inside the case body 41, and the latch portion 451 is moved to be embedded in the locked hole portion 461 by pressing the pressed portion with the latch bolt 46 inserted into the inside of the case body 41 can be used. In addition, as a mechanism for embedding the latch portion 451 in the locked hole portion 461, a mechanism in which the latch portion 451 is moved to be embedded in the locked hole portion 461 based on an electric signal output from the control unit can also be used.

[0138] <Unlocking operation of electronic lock using control unit>

[0139] Next, the unlocking operation of the electronic lock 40 using the control unit will be described. When the user performs an unlocking operation using the operation portion of the touch panel or the like of the control unit, the control unit outputs an electric signal to the electric drive portion 43 of the electronic lock 40. The electric drive portion 43 moves the rod-shaped member based on the electric signal from the control unit, and thereby presses the unlocking lever 44 to the rear side. When the unlocking lever 44 is rotated to the rear side, the lever protruding portion of the unlocking lever 44 moves in a direction away from the rotation protruding portion of the rotation member 45, and thereby the contact of the upper surface of the lever protruding portion with the rotation protruding portion is released. When the contact of the upper surface of the lever protruding portion with the rotation protruding portion is released, the rotation member 45 is rotated to the front side by the urging force of the rotation urging portion, and in a state in which the front end portion of the rotation protruding portion is located in the recess of the lever recess portion, the rotation of the rotation member 45 is restricted. At the timing at which the front end portion of the rotation protruding portion is located in the recess of the lever recess portion, the electric drive portion 43 returns the rod-shaped member to the original position.

[0140] By the rotation of the rotation member 45 to the front side at this time, the latch portion 451 is rotated to be exposed to the outside of the case body 41 (refer to FIG. 7). Figure 13). With the rotation of the latch portion 451, the latch bolt 46 is pushed out to the outside of the case body 41, and the latch portion 451 is disengaged from the upper locking hole portion 461, so the outer door 24 is unlocked and opened. In addition, with the rotation of the forward side of the rotation member 45, the open state retaining portion 452 moves to a position exposed from the cutout 411 of the case body 41. Even if the opened outer door 24 is rotated toward the closing direction, the rotation of the outer door 24 is restricted by the contact of the latch bolt 46 with the open state retaining portion 452 exposed from the cutout 411. As a result, the outer door 24 is maintained in the opened state. In addition, at this time, the inner door 22 is maintained in the closed state by the force of the spring hinge 221 regardless of whether the outer door 24 is opened or not.

[0141] Unlocking operation of electronic lock using unlocking mechanism

[0142] Next, the unlocking operation of the electronic lock 40 using the unlocking mechanism 50 will be described. In the case of a power failure or a control unit failure, or the like, when the shop clerk wants to unlock the outer door 24, the shop clerk inserts a key, not shown, into the keyhole 511 of the operation member 51 in the state shown in Fig. 9, and rotates the key to the left, whereby, as shown in Fig. 10, the unlocking cam 53 is rotated downward to move the unlocking rod 55 downward. With the movement of the unlocking rod 55 downward, as shown in Fig. 11, all the pressing members 57 press the lever pressing portions 561, respectively, to rotate the lever operation member 56 to the rear side. When the lever operation member 56 is rotated to the rear side, the lever pressing portions 561 move to the rear side to press the unlocking lever 44 to the rear side. When the unlocking lever 44 is rotated to the rear side, the locking and unlocking mechanism 42 of the electronic lock 40 operates to unlock the outer door 24, as in the case of the unlocking operation using the control unit. In the case where the outer door 24 is unlocked, the state in which the outer door 24 is opened is maintained by the contact of the open state retaining portion 452 with the latch bolt 46, and the state in which the inner door 22 is closed is maintained by the force of the spring hinge 221. Figure 11 Figure 12 Unlocking operation of electronic lock using unlocking mechanism Figure 13

[0143]

[0144] Next, the unlocking operation of the electronic lock 40 using the unlocking mechanism 50 will be described. In the case of a power failure or a control unit failure, or the like, when the shop clerk wants to unlock the outer door 24, the shop clerk inserts a key, not shown, into the keyhole 511 of the operation member 51 in the state shown in Fig. 9, and rotates the key to the left, whereby, as shown in Fig. 10, the unlocking cam 53 is rotated downward to move the unlocking rod 55 downward. With the movement of the unlocking rod 55 downward, as shown in Fig. 11, all the pressing members 57 press the lever pressing portions 561, respectively, to rotate the lever operation member 56 to the rear side. When the lever operation member 56 is rotated to the rear side, the lever pressing portions 561 move to the rear side to press the unlocking lever 44 to the rear side. When the unlocking lever 44 is rotated to the rear side, the locking and unlocking mechanism 42 of the electronic lock 40 operates to unlock the outer door 24, as in the case of the unlocking operation using the control unit. In the case where the outer door 24 is unlocked, the state in which the outer door 24 is opened is maintained by the contact of the open state retaining portion 452 with the latch bolt 46, and the state in which the inner door 22 is closed is maintained by the force of the spring hinge 221.

[0145] For example, as shown in Fig. 14, the shop clerk opens the outer door 24, and opens the inner door 22 to put the storage object into the inner case 21, and closes the inner door 22. At this time, the spring hinge 221 exerts the force to the inner door 22 in the direction of closing the inner door 22, so the inner door 22 is automatically closed as soon as the hand of the shop clerk is separated from the inner door 22. Figure 14 ​​​As shown, sometimes, the storage target P is sandwiched between the inner case 21 and the inner door 22 due to the manner in which the storage target P is put into the inner case 21, and the inner door 22 fails to close. In this case, even if the clerk does not notice that the inner door 22 is not closed and wants to close the outer door 24, the occlusion prevention member 252 of the occlusion prevention portion 25 contacts the outer surface of the inner door 22 and prevents the outer door 24 from closing.

[0146] In addition, sometimes, after the clerk has put all the storage target P into the inner case 21, or after the customer has taken out the storage target P from the inner case 21, a foreign object is sandwiched between the inner case 21 and the inner door 22, and the inner door 22 fails to close. In this case, likewise, even if the clerk or the customer does not notice that the inner door 22 is not closed and wants to close the outer door 24, the occlusion prevention member 252 of the occlusion prevention portion 25 contacts the outer surface of the inner door 22 and prevents the outer door 24 from closing.

[0147] [Effects of Embodiments]

[0148] The storage device 1 is provided with the air insulation layer K formed in front of the inner case 21. Therefore, even if the temperature around the storage device 1 increases, heat transfer from the surroundings of the storage device 1 to the inside of the inner case 21 can be suppressed. Therefore, even if the storage device 1 is installed outdoors, the temperature change of the storage target P in the inner case 21 can be suppressed. Moreover, the storage device 1 is provided with the occlusion prevention portion 25 that prevents the outer door 24 from closing in a state in which the inner door 22 is not closed. Therefore, the clerk or the customer can easily recognize that the inner door 22 is not closed by recognizing that the outer door 24 is not closed. As a result, in the case in which the inner door 22 is not closed because the storage target P is sandwiched between the inner case 21 and the inner door 22, the storage target P can be suppressed from being damaged. In addition, in the case in which the storage target P is a fresh food or a frozen food, the clerk who finds that the outer door 24 is not closed can quickly put all the storage target P into the inner case 21 and close the inner door 22, and the time during which the storage target P is not in a refrigerated state or a frozen state can be suppressed to a minimum. As a result, the decrease in the commercial value of the storage target P can be suppressed. In the case in which the inner door 22 is not closed because a foreign object is sandwiched between the inner case 21 and the inner door 22, the clerk or the customer who finds that the outer door 24 is not closed can quickly remove the foreign object and then close the inner door 22. In the case in which a foreign object is sandwiched after all the fresh food or frozen food as the storage target P is put into the inner case 21, the time during which the outside air enters the inner case 21 and the temperature in the inner case 21 increases can be suppressed to a minimum, and the decrease in the commercial value of the storage target P can be suppressed. In the case in which a foreign object is sandwiched after the storage target P is taken out from the inner case 21, the time during which the cooling air in the inner case 21 leaks to the outside can be suppressed to a minimum, and unnecessary power consumption of the temperature control unit 100 can be suppressed.

[0149] The occlusion prevention portion 25 has an occlusion prevention member 252 fixed to the inner surface of the outer door 24, which prevents the closing of the outer door 24 in a state where the inner door 22 is not closed by contacting the outer surface of the inner door 22, and allows the closing of the outer door 24 in a state where the inner door 22 is closed. Thus, the user can easily recognize the state where the outer door 24 is not closed by the simple structure of providing the simple occlusion prevention member 252 on the outer door 24. Further, since the occlusion prevention member 252 is provided on the inner surface of the outer door 24, the occlusion prevention member 252 can be prevented from entering the user's field of view when the user opens the inner door 22.

[0150] In the storage device 1, the inner door 22 and the outer door 24 are configured to rotate in the same direction, and the occlusion prevention member 252 is provided on the rotation front end side of the outer door 24. Here, the closer to the rotation front end side of the inner door 22, the greater the distance from the opening surface of the inner opening portion 211 of the inner case 21 to the inner surface of the inner door 22 in plan view. Thus, by providing the occlusion prevention member 252 on the rotation front end side of the outer door 24, the opening amount of the outer door 24 in the state where the closing is prevented by the occlusion prevention member 252 can be greater than in the case where the occlusion prevention member 252 is provided on the rotation base end side. Thus, the user can more easily recognize the state where the outer door 24 is not closed.

[0151] In the case where the outer door 24 is unlocked, the storage device 1 maintains the state where the outer door 24 is open by the open state maintaining portion 452, and maintains the state where the inner door 22 is closed by the urging force of the spring hinge 221. Thus, the user can easily determine the outer door that is unlocked. Further, since the state where the inner door 22 is closed is maintained, the temperature change of the inside of the inner case 21 due to the entry of the outside air into the inner case 21 can be suppressed. Thus, in the case where the storage target is a fresh food or a frozen food, the decrease in the value of the goods due to the temperature change can be suppressed. Moreover, the user does not have to immediately take out the storage target from the inner case 21 after unlocking the outer door 24 in order to avoid the temperature change of the storage target, and can take out the storage target at his or her own pace.

[0152] As the closed state maintaining portion that maintains the state where the inner door 22 is closed, the spring hinge 221 having the function of rotatably connecting the inner door 22 to the inner case 21 and the function of applying a force to the inner door 22 in the direction of closing the inner door 22 is used. Thus, compared to the case where a plurality of members each having one of the two functions described above are used, the number of parts can be reduced.

[0153] The latch portion 451 has a function of locking and unlocking the outer door 24, and the open state maintaining portion 452 has a function of maintaining the state in which the outer door 24 is opened. Thus, without using a mechanism that links the latch portion 451 and the open state maintaining portion 452, the unlocking of the outer door 24 and the maintenance of the state in which the outer door 24 is opened can be performed by rotating the rotation member 45 only once.

[0154] The housing device 1 is provided with an unlocking mechanism 50 for manually unlocking the outer door 24. Thus, even in a case where the electric driving portion 43 does not drive due to a power failure or the like, the outer door 24 can be unlocked, and the convenience of the housing device 1 can be improved. In particular, in a case of a power failure, since the temperature control unit 100 also does not drive, there is a problem that the temperature of fresh food and frozen food as the storage target objects increases and the value of the goods decreases, but since the outer door 24 can be manually unlocked, the fresh food and frozen food can be immediately moved to another refrigerator or freezer.

[0155] The unlocking mechanism 50 is configured in such a manner that the five outer doors 24 can be unlocked at once. Thus, even in a case where it is not possible to determine in which of the five inner boxes 21 the storage target objects are placed, by unlocking the five outer doors 24 at once, it is possible to easily and quickly determine the inner box 21 in which the storage target objects are placed.

[0156] The operation member 51 is provided in such a manner that it is exposed to the outside of the outer box 23. Thus, without performing an operation of opening the box in which the operation member 51 is housed before operating the operation member 51 as in the housing device of the above-described Patent Document 1, the outer door 24 can be quickly unlocked.

[0157] The operation member 51 is configured by a cylinder lock. Thus, in addition to a dedicated key, the outer door 24 cannot be opened, and it is possible to prevent the storage target objects from being stolen.

[0158] [Modifications of the Embodiments]

[0159] Of course, the present application is not limited to the contents shown in the embodiments explained so far, and various modifications can be made within the scope of the inventive concept thereof.

[0160] The blocking preventing portion 25 can be provided only on the outer surface of the inner door 22. When the blocking preventing portion 25 is provided on the outer surface of the inner door 22, a door opening / closing operation portion (a handle, a knob, or the like) that is operated when the inner door 22 is opened and closed can be provided on the blocking preventing portion 25. If such a structure is employed, the blocking preventing portion 25 can have a function of preventing the outer door 24 from being closed and an operation function when the inner door 22 is opened and closed, and thus it is not necessary to provide the operation groove portion 223 on the inner door 22.

[0161] A buffer portion can also be provided at the front end of the occlusion preventing member 252. If such a structure is employed, damage to the inner door 22 when the occlusion preventing member 252 comes into contact with the inner door 22 can be avoided.

[0162] The occlusion preventing member 252 can also be provided at the center in the left-right direction of the inner door 22 or the outer door 24, and the occlusion preventing member 252 can also be provided at the base end side of the rotation.

[0163] A sliding door can also be employed as the inner door and the outer door. For example, in a case where an inner door and an outer door that close the inner opening portion and the outer opening portion, respectively, by sliding downward are employed, the occlusion preventing portion can be constituted by a first occlusion preventing member that extends from the outer surface of the inner door to the outer door side, and a second occlusion preventing member that extends from the inner surface of the outer door to the inner door side, and the second occlusion preventing member can contact the upper portion of the first occlusion preventing member in a state where both the inner door and the outer door are closed. In such a structure, since the first occlusion preventing member rises to a higher position in a state where the inner door is not closed than in a state where the inner door is closed, the second occlusion preventing member also rises to a higher position in a state where the inner door is not closed than in a state where the inner door is closed, thereby preventing the outer door from being closed.

[0164] A structure other than the spring hinge 221, such as a structure that attracts the inner door 22 to the inner case 21 by magnetic force, can also be employed as the closed state retaining portion. In this case, the inner door 22 can be rotatably connected to the inner case 21 by a hinge that does not have a spring.

[0165] A structure in which the opening state retaining portion 452 is not provided on the rotation member 45 of the electronic lock 40, but is moved to be exposed from the cutout 411 in linkage with the rotation of the rotation member 45 toward the front side, for example, and retains the state where the outer door 24 is open by contact with the latch 46 can also be employed.

[0166] The unlocking mechanism 50 can also not be provided in the housing device 1. Alternatively, five unlocking mechanisms that each unlock one outer door 24 can be provided.

[0167] The operation member 51 can also be provided inside the outer case 23, and a door for hiding the operation member 51 from the outside can be provided on the outer case 23. A structure in which a cylinder lock is not used as the operation member 51, but a structure in which anyone can operate without a special key can be used. In this case, it is preferable to restrict the personnel who can operate the operation member by providing the operation member at a position such as the lower end portion of the outer case 23 that is not easily seen by customers, or by providing the operation member inside the outer case 23 and providing a door with a lock.

[0168] In the storage device 1, a temperature control unit that heats the storage target can be provided. In the storage device 1, a temperature control unit that controls the temperature of each storage section 20 individually can be provided. The temperature control unit 100 can not be provided in the storage device 1.

[0169] In the storage device 1, a device that locks and unlocks with a key can be provided instead of the electronic lock 40. In the storage device 1, the device that locks and unlocks the outer door 24, such as the electronic lock 40, can not be provided.

[0170] The storage target stored in the storage device 1 can be any of a food, a beverage, a medicine, a daily necessity, a grocery, an electronic device, a book, or the like, other than a fresh food and a frozen food, that can be stored in the storage device 1.
