[0012] An embodiment of the present invention will be described with reference to Figs. 1 to 12. In this embodiment, as shown in Fig. 1, a refrigerated storage cabinet 10 is exemplified as the storage cabinet. As shown in Figs. 1 and 2, the refrigerated storage cabinet 10 includes a box-shaped storage cabinet main body 12 (insulated box) that constitutes a storage chamber 11 in which stored items are accommodated. As shown in Fig. 2, the storage chamber 11 is open at the front and is partitioned into upper and lower sections by a wire shelf 22 that extends horizontally. This divides the storage chamber 11 into two storage chambers 11A and 11B that are arranged vertically.

[0013] As shown in Figure 1, a pair of left and right doors 16, 16 are attached to the storage cabinet main body 12. Each door 16 is attached to the side edge of the storage cabinet main body 12 so that it can rotate relative to the storage cabinet main body 12. This allows the storage chamber 11 to be opened and closed by the doors 16. The storage cabinet main body 12 is also supported by wheels 18 provided at the four corners of the bottom surface. This allows the cooling storage cabinet 10 to be moved using the wheels 18.

[0014] A machine room 20 is disposed above the storage room 11. As shown in FIG. 4, the machine room 20 accommodates a compressor 25 that compresses the refrigerant, a condenser 26, and a condenser fan 27 that cools the condenser 26. The compressor 25, the condenser 26, and a plurality of coolers 28 (see FIGS. 3 and 4), which will be described later, are connected by refrigerant piping 24 (see FIG. 3) to form a cooling cycle. A non-flammable refrigerant (e.g., R448A) is sealed inside the refrigerant piping 24. However, the refrigerant is not limited to this, and a flammable refrigerant (e.g., propane, isobutane, etc.) may also be used. The cooler 28 is capable of cooling the surroundings by evaporating the refrigerant compressed by the compressor 25.

[0015] 3, the walls constituting the storage body 12 have a double structure including an outer wall 13 made of a metal plate such as a stainless steel plate, and an inner wall 14 made of a metal plate such as a stainless steel plate and disposed inside the outer wall 13. The space between the outer wall 13 and the inner wall 14 is filled with a foamed insulating material 15 made of a foamed resin such as urethane foam.

[0016] Inner wall 14 is a wall that constitutes storage chamber 11, and cooler 28 is disposed corresponding to the inner surface of storage chamber 11A, which is disposed above storage chamber 11A, of storage chambers 11A and 11B. More specifically, cooler 28 abuts against each of the outer surfaces of storage chamber 11A on inner wall 14. In other words, cooler 28 is disposed on the outer side of storage chamber 11A on inner wall 14.

[0017] Also, a cooling unit 40 is arranged on the inner surface of storage chamber 11A. As shown in Figures 3 and 4, cooling units 40 are arranged on ceiling surface 17A, left and right side surfaces 17B, 17B, and rear surface 17C of the inner surface of storage chamber 11A. In the following explanation, the configuration of cooling unit 40 will be explained using cooling unit 40 arranged on rear surface 17C as an example. In the following explanation, the wall portion of inner wall 14 that constitutes rear surface 17C will be referred to as rear wall 14C (wall portion that constitutes storage chamber 11).

[0018] 5 to 7, the cooling unit 40 includes a plurality of ice packs 41, a plurality of holding members 50 that hold the plurality of ice packs 41, extension members 60, 61, and 62 for attaching the holding members 50 to the rear wall portion 14C, and a pair of left and right lattice-shaped covers 70 that cover the plurality of holding members 50. In the cooling unit 40 disposed on the rear surface 17C, as shown in FIG. 6, the holding members 50 are arranged in three stages and are arranged in two rows in the left-right direction. Also, as shown in FIG. 7, two ice packs 41 are held by one holding member 50. Note that the number of ice packs 41 held by the holding members 50 and the number of holding members 50 can be changed as appropriate.

[0019] 8, one cooler 28 is arranged so as to overlap six ice packs 41 arranged in two rows and three columns. The cooler 28 is constructed by bending a metal (e.g., copper) pipe, and includes a plurality of straight sections 29 and bent sections 30 that connect the ends of the straight sections 29. A plurality of straight sections 29 of the cooler 28 (four in FIG. 8) are arranged so as to overlap one ice pack 41.

[0020] 10, ice pack 41 has a flexible bag body 43 formed by joining the outer peripheral edges of a pair of opposing film materials 42, 42 together by a joining means such as heat welding, and a filler material 44 filled inside bag body 43. Film material 42 is made of a metal film such as aluminum, and is flexible. Filler material 44 is made of, for example, water, but may also be made of other materials (for example, a highly water-absorbent polymer impregnated with water).

[0021] 9 and 10, the ice pack 41 has a contact surface 45 that contacts the rear surface 17C (the inner surface of the storage chamber at the wall portion). The ice pack 41 has a rectangular plate shape and includes an ice pack main body 46 that constitutes the contact surface 45, and an outer peripheral edge portion 47 that is provided around the entire outer peripheral end surface of the ice pack main body 46.

[0022] The portion of the outer peripheral end 47 that forms the upper end is a first extending portion 47A. As shown in Fig. 10, the first extending portion 47A extends from a first outer peripheral end surface 46A that is an upper portion (one side in the direction along the abutment surface 45) of the outer peripheral end surface of the ice pack main body 46, and its tip extends toward the back wall 14C. In other words, the tip of the first extending portion 47A is bent with respect to the base end.

[0023] Furthermore, the portion of outer peripheral end 47 that forms the lower end is defined as second extending portion 47B. Second extending portion 47B extends from second outer peripheral end surface 46B, which is the lower portion (the other side in the direction along contact surface 45) of the outer peripheral end surface of ice pack main body 46, and its tip extends toward rear wall 14C. In other words, second extending portion 47B has its tip bent with respect to its base end.

[0024] The first extending portion 47A and the second extending portion 47B are formed by the outer peripheral edge portion (the joint portion of the pair of film materials 42, 42) of the bag body 43. That is, the first extending portion 47A and the second extending portion 47B are flexible. The first extending portion 47A forms one of a pair of end portions, which are the upper and lower end portions of the ice pack 41 (end portions of the ice pack in different directions), and the second extending portion 47B forms the other of the pair of end portions.

[0025] As shown in Fig. 10, the holding member 50 is disposed on the inner surface (left side in Fig. 10) of the storage chamber 11A in the rear wall portion 14C. The holding member 50 is made of a metal (stainless steel, aluminum, etc.) plate material, and includes a rectangular cover portion 51 that covers the surface 41A of the ice pack 41 opposite to the contact surface 45, and a pair of locking portions 52, 53 that lock the first extending portion 47A and the second extending portion 47B (a pair of ends). The pair of locking portions 52, 53 are formed by bending the outer periphery of the plate material that constitutes the holding member 50.

[0026] Locking portion 52 includes base end 52A extending from the surface of cover 51 facing ice pack main body 46 toward rear wall 14C (the right side in FIG. 10), and tip end 52B folded back from base end 52A. Locking portion 53 includes base end 53A extending from the surface of cover 51 facing ice pack main body 46 toward rear wall 14C, and tip end 53B folded back from base end 53A.

[0027] Tip 52B of locking portion 52 (tip of one of the pair of locking portions) locks with first extending portion 47A from the ice pack main body 46 side (lower side in FIG. 10). Tip 53B of locking portion 53 (tip of the other of the pair of locking portions) locks with second extending portion 47B from the ice pack main body 46 side (upper side in FIG. 10).

[0028] Next, the configuration of extension members 60, 61, 62 will be described. In cooling unit 40 arranged on rear surface 17C, as shown in Fig. 6, holding members 50 are arranged in three vertical stages and are aligned in two rows in the left-right direction. Extension members 60 are arranged on both side edges of each group of six holding members 50. Extension members 60 extend along the side edges of the group of six holding members 50. Extension members 61, 62 are arranged between two holding members 50 aligned in the left-right direction.

[0029] As shown in FIG. 6, the extension member 60 extends along the outer peripheral edges (side edges) of the multiple cover portions 51, and as shown in FIG. 11, the extension member 60 is fastened to the rear wall portion 14C with fastening members 19 (screws, etc.). The extension member 60 is a plate member having a stepped cross section, and has a fastening portion 60A that is fastened to the rear wall portion 14C and an abutting portion 60B that abuts against the outer peripheral edges of the cover portions 51 from the inside of the storage chamber 11A (the upper side in FIG. 11). In addition, a reinforcing member 21, which is a plate member having a U-shape in cross section, is attached to the surface of the rear wall portion 14C facing outside the storage chamber 11A (the lower side in FIG. 11) at the fastening point of the fastening member 19. The fastening member 19 is fastened to both the rear wall portion 14C and the reinforcing member 21.

[0030] 11, the extension member 61 is fastened to the rear wall portion 14C by fastening members 19. The extension member 61 is a plate material and has a fastening portion 61A that is fastened to the rear wall portion 14C, and a pair of abutting portions 61B, 61B that abut against each side end of two adjacent cover portions 51 from inside the storage chamber 11A. Each abutting portion 61B forms a step relative to the fastening portion 61A.

[0031] 6, the extension member 62 is fastened to the rear wall portion 14C by fastening members 19. The extension member 62 is a plate material and has a fastening portion 62A that is fastened to the rear wall portion 14C, and a pair of abutting portions 62B, 62B that abut against each side end of two adjacent cover portions 51 from the inside of the storage chamber 11A. Each abutting portion 62B forms a step relative to the fastening portion 62A.

[0032] By fastening the extension members 60, 61, and 62 to the rear wall portion 14C, the contact portions 60B, 61B, and 62B can press the cover portion 51 toward the rear wall portion 14C. As a result, as shown in FIG. 10 , the cover portion 51 is configured to sandwich the ice pack 41 between itself and the inner surface (rear surface 17C) of the storage chamber 11 in the rear wall portion 14C. Note that, as shown in FIG. 10 , the thickness (length in the left-right direction in FIG. 10 ) of the ice pack main body 46 is set to a value greater than the extension length (length in the left-right direction in FIG. 10 ) of the base end portion 52A of the locking portion 52. As a result, when the ice pack 41 is sandwiched between the cover portion 51 and the rear wall portion 14C, the locking portion 52 and the rear wall portion 14C do not interfere with each other, and the ice pack main body 46 can be in close contact with both the cover portion 51 and the rear wall portion 14C. As shown in FIG. 6, the extension member 60 has a bottom wall portion 60D that supports the side end portion of the holding member 50 from below, and the extension member 62 has a bottom wall portion 62D that supports the side end portion of the holding member 50 from below.

[0033] 12, the two ice packs 41, 41 held by one holding member 50 are arranged side by side in the longitudinal direction of the holding member 50 (the left-right direction in FIG. 12), with the side ends 48 of the two ice pack main bodies 46 overlapping each other. This prevents gaps from occurring between the two ice packs 41, 41.

[0034] The refrigerated storage cabinet 10 also includes a storage compartment temperature sensor 81 that detects the temperature of the storage compartment 11, and a cold pack temperature sensor 82 that detects the temperature of the cold pack 41. As shown in Fig. 3, the storage compartment temperature sensor 81 is housed in a case 83 that is disposed directly below the wire shelf 22 in the storage compartment 11B. The cold pack temperature sensor 82 is disposed on the surface of the holding member 50, for example.

[0035] In the cooling operation, a control unit (not shown) controls each device (compressor 25, condenser fan 27, etc.) based on the temperature detected by storage chamber temperature sensor 81. For example, when the temperature detected by storage chamber temperature sensor 81 is equal to or higher than a set temperature TA (e.g., 2°C), the control unit operates each device related to the cooling operation, and when the temperature detected by storage chamber temperature sensor 81 falls to or lower than a set temperature TB (e.g., -1°C), the control unit stops each device.

[0036] Furthermore, during cooling operation, the control unit controls the lighting of an indicator lamp 84 (see FIG. 1) provided on the front surface of the storage cabinet main body 12 based on the temperature detected by the ice pack temperature sensor 82. Specifically, when the temperature detected by the ice pack temperature sensor 82 is equal to or lower than a set temperature TC (e.g., −5° C.), the control unit determines that the ice pack 41 is in a frozen state and lights up the indicator lamp 84. When the temperature detected by the ice pack temperature sensor 82 is equal to or higher than a set temperature TD (e.g., −2° C.), the control unit determines that the ice pack 41 is in a molten state and turns off the indicator lamp 84.

[0037] Next, the effects of this embodiment will be described. Refrigerated storage cabinet 10 according to this embodiment includes box-shaped storage cabinet main body 12 constituting storage chamber 11A in which storage items are accommodated, cooler 28 arranged outside storage chamber 11A in rear wall 14C (a wall constituting storage chamber 11A), flexible ice pack 41 having a contact surface 45 that contacts the inner surface of storage chamber 11A in rear wall 14C, and holding member 50 arranged on the inner surface of storage chamber 11A in rear wall 14C to hold ice pack 41. Holding member 50 includes cover 51 that covers surface 41A of ice pack 41 opposite contact surface 45, and a pair of locking portions 52, 53 that lock first extending portion 47A and second extending portion 47B (a pair of ends) that are end portions of ice pack 41 in different directions.

[0038] By using the cooler 28 to cool the ice pack 41 through the rear wall 14C, the storage chamber 11A can be cooled by the ice pack 41 even when there is no external power supply. The holding member 50 also includes a pair of locking portions 52, 53 that lock the first extension 47A and the second extension 47B of the ice pack 41. This prevents the flexible ice pack 41 from deforming due to its own weight. This allows the ice pack 41 to be more reliably attached to the rear wall 14C, allowing the cooler 28 to efficiently cool the ice pack 41. Furthermore, by covering the ice pack 41 from the side opposite the contact surface 45 with the cover portion 51, the ice pack 41 can be prevented from coming into contact with the stored item, thereby protecting the ice pack 41.

[0039] The ice pack 41 is plate-shaped and includes an ice pack main body 46 constituting the contact surface 45, a first extending portion 47A (one of a pair of ends) extending from a first outer peripheral end surface 46A, which is one portion of the outer peripheral end surface of the ice pack main body 46 in the direction along the contact surface 45, and extending with its tip toward the rear wall portion 14C, and a second extending portion 47B (the other of the pair of ends) extending from a second outer peripheral end surface 46B, which is the other portion of the outer peripheral end surface of the ice pack main body 46 in the direction along the contact surface 45, and extending with its tip toward the rear wall portion 14C. Each of the pair of locking portions 52, 53 has base ends 52A, 53A extending from the surface of the cover portion 51 facing the ice pack main body 46 toward the rear wall portion 14C, and tip ends 52B, 53B folded back from the base end 52A, and tip end 52B of locking portion 52 (one of the pair of locking portions) locks with the first extension portion 47A from the ice pack main body 46 side, and tip end 53B of locking portion 53 (the other locking portion of the pair of locking portions) locks with the second extension portion 47B from the ice pack main body 46 side.

[0040] By engaging the first extending portion 47A (or the second extending portion 47B) with the distal end portion 52B (or the distal end portion 53B) folded back relative to the proximal end portion 52A (or the proximal end portion 53A), the first extending portion 47A (or the second extending portion 47B) can be covered by the engaging portions 52, 53 from the side facing away from the covering portion 51. This prevents the first extending portion 47A and the second extending portion 47B from being displaced away from the covering portion 51. In this embodiment, the holding member 50 is attached to the rear wall portion 14C with two ice packs 41 attached to it. According to the above configuration, when the holding member 50 holding the ice packs 41 is placed on the inner surface of the storage chamber 11A, it is possible to more reliably prevent the ice packs 41 from falling off the holding member 50.

[0041] The ice pack 41 also includes a bag body 43 formed by joining the outer peripheral ends of a pair of oppositely arranged film materials 42, 42 together, and a filler material 44 filled inside the bag body 43, and the first extension portion 47A and the second extension portion 47B are formed by the outer peripheral ends of the bag body 43.

[0042] The outer peripheral edge of the bag body 43, which is formed by the outer peripheral edges of the pair of film materials 42, 42, can be easily bent. With such an outer peripheral edge of the bag body 43, the first extending portion 47A and the second extending portion 47B (having a shape in which the tip extends toward the wall portion) can be easily formed.

[0043] The holding member 50 further includes an extension member 60 that extends along the outer peripheral edge of the cover portion 51 and is fastened to the rear wall portion 14C by fastening members 19. The extension member 60 has an abutting portion 60B that abuts against the outer peripheral edge of the cover portion 51 from inside the storage chamber 11A, and the cover portion 51 is configured to sandwich the ice pack 41 between itself and the inner surface of the storage chamber 11A at the rear wall portion 14C. Fastening the extension member 60 to the rear wall portion 14C allows the holding member 50 to be attached to the rear wall portion 14C. Furthermore, sandwiching the ice pack 41 between the cover portion 51 and the inner surface of the storage chamber 11A at the rear wall portion 14C allows the ice pack 41 to be more reliably in close contact with the inner surface of the storage chamber 11A at the rear wall portion 14C.

[0044] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included in the technical scope. (1) In the above embodiment, the ice pack 41 is exemplified as being rectangular in shape, but the shape of the ice pack 41 is not limited to this and can be changed as appropriate. (2) In the above embodiment, the pair of locking portions provided on the holding member 50 are exemplified as a pair of locking portions 52, 53 that lock both the upper and lower ends of the ice pack 41, but the locking locations of the ice pack 41 are not limited to this. The pair of locking portions may be configured to lock a pair of ends, which are end portions of the ice pack in different directions, and may be configured to lock, for example, the upper end and side end of the ice pack 41.
