Description

[Technical Field]

[0001] The present disclosure relates to refrigerated storage. [Background technology]

[0002] Conventionally, refrigerated storage cabinets are known from Patent Documents 1 and 2. The refrigerated storage cabinet (refrigerator) described in Patent Document 1 is composed of an insulated box and a machine room (a freezing unit storage section) disposed above the insulated box, and the insulated box is composed of a refrigerator body and an insulated door that is openably and closably attached to an opening on the front of the refrigerator body. A packing member made of a material such as rubber is attached to the outer periphery of the inner surface of the insulated door, and this packing member abuts against the front end surface of the refrigerator body. This prevents cold air from inside the refrigerator body from leaking outside, and keeps the interior of the refrigerator airtight.

[0003] On the other hand, the refrigerated storage cabinet (refrigerator) described in Patent Document 2 includes an insulated box and an upper machine room provided on top of the insulated box, and the upper machine room is provided with, in order from windward, an upwind louver, an air-cooled condenser, a blower, a compressor, and a downwind louver. By driving the blower, negative pressure is created on the upwind side of the upper machine room, and air is taken into the upper machine room through the upwind louver. The air taken into the upper machine room cools the air-cooled condenser and compressor, and is then discharged out of the upper machine room through the downwind louver. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-227271 [Patent Document 2] Japanese Patent Application Publication No. 2017-203602 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the configuration disclosed in Patent Document 1, although the packing member prevents gas from entering or leaving the refrigerator body, if water such as rainwater gets on the refrigerated storage compartment, depending on the amount of water, there is a possibility that water may enter the refrigerated storage compartment through the gap between the packing member and the refrigerated storage compartment.If items are stored in the refrigerated storage compartment or a cooler capable of cooling these items is installed in the refrigerated storage compartment, there is a risk that the water that enters the refrigerated storage compartment will freeze the stored items or the cooler, thereby reducing the cooling performance of the refrigerated storage compartment.

[0006] On the other hand, with the configuration disclosed in Patent Document 2, if water such as rainwater gets on the cooling storage cabinet, there is a risk that water will enter the upper machine room through the windward louvers, leeward louvers, etc. If a control unit, electrical wiring, etc. is installed in the upper machine room, water entering the upper machine room could cause the control unit to malfunction or cause a short circuit at the electrical wiring connection. Furthermore, when the blower is driven, water is more likely to enter the upper machine room along with the air drawn in through the windward louvers, and water that has entered the upper machine room is dispersed by the blower, increasing the risk of the control unit malfunctioning.

[0007] The present disclosure was completed in light of the above circumstances, and one of its objectives is to provide a cooling storage cabinet that is resistant to water intrusion and that can effectively drain water even if water does get inside. [Means for solving the problem]

[0008] The present disclosure relates to a refrigerated storage facility comprising: a box body having an opening that opens forward and capable of storing items inside; and a door that opens and closes the opening, wherein the door comprises a main body portion, a gasket that is provided on the main body portion and abuts the opening when the door is in a closed state where the opening is closed; and a door-side extension portion that is arranged closer to the end of the main body portion than the gasket and extends rearward from the main body portion, wherein the opening portion comprises an opposing portion that faces the main body portion in the closed state and an opening-side extension portion that extends forward from the opposing portion, and wherein the front end of the opening-side extension portion is located between the gasket and the door-side extension portion and forward of the rear end of the door-side extension portion in the closed state.

[0009] In this type of refrigerated storage cabinet, when the door is in the closed state with the opening closed, the door-side extension extending rearward from the main body is positioned closer to the end of the main body than the door gasket. The front end of the opening-side extension extending forward from the facing portion is located between the gasket and the door-side extension and forward of the rear end of the door-side extension. Therefore, even if water splashes on the refrigerated storage cabinet and moves between the door and the box, it will not move toward the gasket unless it passes over the rear end of the door-side extension. Even if the water does pass the rear end, its front end will hit the opening extension, which is located between the gasket and the door-side extension and forward of the rear end of the door-side extension, preventing the water from splashing directly on the gasket. This prevents water from entering the box through the gap between the opening and the gasket.

[0010] In the above configuration, the door-side extension portion may include a door-side first extension portion located closer to the upper end of the main body portion than the packing, and the opening-side extension portion may include an opening-side first extension portion whose front end is located between the packing and the door-side first extension portion in the closed state, and the opening-side first extension portion may include an extending main body portion extending toward the side of the opening, and a rising portion located forward of the rear end of the door-side first extension portion and rising from the extending main body portion.

[0011] With this type of refrigerated storage cabinet, even if water gets into the refrigerated storage cabinet, the water can drip from the rear end of the door-side first extension portion onto the extension main body portion of the opening-side first extension portion and be received by the water. The rising portion then blocks the water received by the extension main body portion, preventing it from moving toward the gasket. Furthermore, because the extension main body portion extends toward the side of the opening, the water received by the extension main body portion can be drained toward the side of the opening.

[0012] In the above configuration, the door-side extension portion may include a door-side second extension portion located closer to the lateral end of the main body portion than the packing, the opening-side extension portion may include an opening-side second extension portion whose front end portion is located between the packing and the door-side second extension portion in the closed state, and the opening-side first extension portion may have a rising portion that extends downward from the lateral end of the extension main body portion and overlaps with the upper end of the opening-side second extension portion.

[0013] With this type of refrigerated storage cabinet, water that runs down the side of the cabinet or splashes from the side can be directed onto the opening-side second extension portion, preventing the water from splashing directly onto the packing. Also, water that is received by the extension main body of the opening-side first extension portion and moves to the side can be efficiently conveyed to the opening-side second extension portion by the rising portion and drained.

[0014] In the above configuration, the opening may include a key portion that locks the door so that the door does not change from the closed state to an open state in which the opening is open, the door side extension portion may include a door side second extension portion that is located closer to the lateral end of the main body portion than the gasket, and the opening side extension portion may include an opening side second extension portion whose front end portion is located between the gasket and the door side second extension portion and that forms part of the key portion.

[0015] According to such a cooling storage cabinet, the functional member (key portion) also serves as a door locking member, making it possible to prevent water from coming into direct contact with the packing.

[0016] In the above configuration, the door-side extension portion includes a first door-side extension portion located closer to the upper end of the main body portion than the packing, a second door-side extension portion located closer to the lateral end of the main body portion than the packing, and a third door-side extension portion located closer to the lower end of the main body portion than the packing, and the opening-side extension portion may include, in the closed state, a first opening-side extension portion whose front end is located between the packing and the first door-side extension portion, a second opening-side extension portion whose front end is located between the packing and the second door-side extension portion, and a third opening-side extension portion whose front end is located between the packing and the third door-side extension portion.

[0017] Such a refrigerated storage cabinet can prevent water from directly contacting the packing around the entire periphery of the door.

[0018] In the above configuration, the box body may have a hinge portion attached in a manner that allows the door to rotate, and the door may have a partition portion that separates a hollow internal space, and a hole portion provided inside the door on the hinge portion side of the partition portion.

[0019] In this type of refrigerated storage cabinet, even if water enters the door from the hinge side, the partition wall can prevent the water from moving into spaces within the door's interior other than the hinge side. Furthermore, water that has entered the space within the door's interior on the hinge side can be drained through the hole. For example, if a thermal insulator is placed in the space within the door's interior other than the hinge side, this is advantageous because it can prevent the thermal insulator from getting wet.

[0020] In the above configuration, the box body has a drainage channel extending in the vertical direction, and the cooling storage cabinet has a machine room provided above the box body, and the machine room has an intake panel with an intake side opening, a condenser provided on the indoor side of the intake panel, and a condenser fan that is driven by itself to draw in outside gas from the intake side opening and cool at least the condenser, and a gutter section that is located below the intake side opening and extends at an angle upward toward the drainage channel may be provided between the intake panel and the condenser.

[0021] With this type of refrigerated storage cabinet, water that enters the machine room through the intake-side opening of the intake panel is received by a gutter located below the intake-side opening between the intake panel and the condenser, and can then be channeled toward the drainage channel.The water then passes through the drainage channel that extends vertically, providing a refrigerated storage cabinet that can be efficiently drained toward the bottom of the box.

[0022] In the above configuration, the box body may include a hinge portion to which the door is attached in a manner that allows the door to rotate, and the drainage channel may be provided on the side of the hinge portion.

[0023] In such a refrigerated storage facility, a drainage channel is provided on the side of the hinge portion, so that water can be drained from the machine room while avoiding the end of the door opposite the hinge portion, which is the end that moves away from or close to the opening when the door is opened or closed. [Effects of the Invention]

[0024] According to the present disclosure, it is possible to provide a cooling storage cabinet that is resistant to water intrusion, and also to provide a cooling storage cabinet that can effectively drain water even if water does intrude into the interior. [Brief explanation of the drawings]

[0026] <Embodiment> An embodiment of the present disclosure will be described with reference to Figures 1 to 17. In this embodiment, a locker-type refrigerated storage cabinet 10 is exemplified as the refrigerated storage cabinet. In each figure, the arrow direction L indicates the left, the arrow direction R indicates the right, the arrow direction F indicates the front, the arrow direction B indicates the rear, the arrow direction U indicates the up, and the arrow direction D indicates the down.

[0027] As shown in FIG. 1 , a plurality of refrigerated storage cabinets 10, each equipped with an operation terminal 80, are lined up adjacent to one another to form a group of refrigerated storage cabinets 1. The refrigerated storage cabinets 10 are installed, for example, in front of a store or inside a shopping mall, and can store beverages, food, medicines, and other stored items in a locked state while keeping them cool. The refrigerated storage cabinets 10 are used by users (e.g., purchasers) to receive packages stored by providers (e.g., store clerks or delivery personnel), but their uses are not limited thereto. For example, they may be used by users to temporarily store packages in a refrigerated state. Furthermore, depending on the use and installation location, only one refrigerated storage cabinet 10 may be installed and used, rather than multiple cabinets.

[0028] The operation terminal 80 provided in the refrigerated storage cabinet 11 is an information terminal equipped with at least one of input means 80A such as an operation panel or reading means 80B such as a barcode reader, and may be a known terminal such as a tablet terminal or a computer. The user can unlock or lock the locking device (key unit 140) that locks the door 22 by inputting a password into the operation panel or by having a barcode reader read a two-dimensional barcode.

[0029] As shown in Figures 2 and 3, the refrigerated storage cabinet 10 has an overall shape of a vertically elongated rectangular parallelepiped. The refrigerated storage cabinet 10 includes a box body 12 capable of storing storage items therein, and a machine room 13 provided above the box body. The box body 12 includes an opening 20 (see Figure 13) that opens to the front, a plurality of hinge portions 21 provided at the front right end portion of the opening 20, and a plurality of doors 22 that rotate forward about the hinge portions 21 to open and close the opening 20. Providers and users (hereinafter, sometimes referred to as users, etc.) can put storage items in and take them out of the box body 12 by opening and closing the doors 22.

[0030] As shown in FIG. 11 , the right end 100C side of the main body 100 of one door 22 is attached to the hinge portions 21 located on both the upper and lower sides thereof via a rear shaft portion 21A and a front shaft portion 21B. The rear shaft portion 21A rotatably connects the right side portion of the upper end 100A of the main body 100 to the hinge portion 21 located above it. The front shaft portion 21B rotatably connects the right side portion of the lower end 100B of the main body 100 to the hinge portion 21 located below it, and is located forward of the rear shaft portion 21A. The rear shaft portion 21A and the front shaft portion 21B located on both the upper and lower sides of one door 22 are not aligned vertically, and the axis connecting them (the pivot axis of the door 22) tilts forward as it extends downward. When a user pulls handle 108 (see FIGS. 2 and 17) to open door 22, upper end 100A of main body 100 tilts slightly backward, and main body 100 rotates while being slightly displaced upward as a whole. When a user releases their fingers from handle 108, door 22 returns from the open state to the closed state under its own weight.

[0031] 2 and 3, the box 12 is surrounded by plate-like side panels 23, 24 provided on the left and right sides and having plate surfaces extending in the front-to-back and up-down directions, and a plate-like back panel 25 provided on the rear side and having plate surfaces extending in the left-to-right and up-down directions. Each of the panels 23, 24, 25 has a double structure consisting of an outer wall and an inner wall attached to the inside of the outer wall, and a heat insulating material such as urethane foam is filled between the outer wall and the inner wall. The upper part 23A of the right side panel 23 forms the right wall portion of the machine room 13.

[0032] The box body 12 includes a first drainage channel (drainage channel) 26, a second drainage channel 27, and a third drainage channel 28, each extending in the vertical direction. The first drainage channel 26 is provided between the right end of the door 22 and the right side panel 23, to the right of the hinge portion 21 (to the side of the hinge portion 21), forming a right front corner of the box body 12, and has a tubular shape with a rectangular cross section. A gap is provided between the first drainage channel 26 and the right end of the door 22 and the hinge portion 21 (see FIG. 8). The upper end of the first drainage channel 26 is an inlet 26A that has a rectangular frame shape when viewed from above, with the long sides extending in the front-to-rear direction. The second drainage channel 27 is provided between the right side panel 23 and the back panel 25, forming a right rear corner of the box body 12, and like the first drainage channel 26, has a tubular shape with a rectangular cross section. The third drainage channel 28 is provided between the left side panel 24 and the back panel 25, forming a left rear corner of the box body 12, and has a tubular shape with a square cross section, similar to the first drainage channel 26 and the second drainage channel 27. Each of the drainage channels 26, 27, 28 allows water flowing from the machine room 13 to flow downwards in the box body 12 and be discharged outside the refrigerated storage cabinet 10.

[0033] As shown in Fig. 4, the interior 14 (hereinafter sometimes referred to as storage chamber 14) of the box 12 is provided with a cooler chamber 30 that houses a cooler (evaporator) 35, a circulation fan, etc., and a plurality of shelves 32 that divide the storage chamber 14 into a plurality of vertically arranged spaces 14A. A vertically extending hollow right duct 31 is provided inside the right side panel 23. A vertically extending hollow left duct (not shown) is provided inside the left side panel 24, similar to the right duct 31. The right duct 31 is provided with a plurality of holes 31A. The left duct is provided with a plurality of holes (not shown), similar to the right duct 31.

[0034] A rectangular pillar-shaped frame 29 extending in the left-right direction is provided in front of each shelf 32. The frame 29 is filled with a heat insulating material such as urethane foam, and serves as a portion against which both upper and lower ends of a packing 150 provided on the inner surface of the door 22 abut. The multiple doors 22 are attached to the respective hinge portions 21 so that the spaces 14A partitioned by the multiple shelf plates 32 can be opened and closed, respectively.

[0035] When the circulation fan is activated, gas in the storage chamber 14 flows into the left duct through the holes in the left duct, rises within the left duct, and flows into the cooler chamber 30. The gas that flows into the cooler chamber 30 is cooled by heat exchange as it passes through the cooler 35, becoming cold air. This cold air flows out from the cooler chamber 30 into the right duct 31, flows downward within the right duct 31, and is blown out into the storage chamber 14 through the multiple holes 31A. In this way, the gas in the storage chamber 14 is cooled while circulating.

[0036] As shown in FIGS. 1 and 2, the machine room 13 includes a plate-shaped intake panel 40 having a plurality of intake-side openings 41 and constituting a front wall, an upper portion 23A of a plate-shaped side panel 23 constituting a right wall, a plate-shaped side panel 43 constituting a left wall, a plate-shaped exhaust panel 44 having a plurality of exhaust-side openings 45 and constituting a rear wall, and a plate-shaped upper panel (top panel) 48 constituting an upper wall. A front end 23A1 (see FIG. 8) of the upper portion 23A of the right side panel 23 is attached to a right end (side end) 40B of the intake panel 40. An inlet 26A of a first drainage channel 26 is located below the front end 23A1. A front end 43A of the left side panel 43 is attached to a left end (side end) 40A of the intake panel 40. A right end of the exhaust panel 44 is attached to a rear end 23A2 of the upper portion 23A of the right side panel 23. The left end of an exhaust panel 44 is attached to the rear end 43B of the left side panel 43.

[0037] As shown in Fig. 5, the interior of the machine chamber 13 contains a compressor 51 that compresses refrigerant gas, a condenser 52 that cools and liquefies the compressed refrigerant gas, an expansion valve that expands the liquefied refrigerant, and a condenser fan 53 that operates to draw gas through a plurality of intake-side openings 41 to cool the condenser 52 and the compressor 51. The compressor 51, condenser 52, expansion valve, and cooler 35 are connected in this order by a refrigerant pipe 54, and the refrigerant is circulated, thereby constituting a cooling device 50 that forms a known refrigeration circuit (refrigeration cycle). A cylindrical heat insulating material is partially attached to the refrigerant pipe 54.

[0038] The condenser 52 and the condenser fan 53 are provided on the indoor side (rear side) of the intake panel 40, behind a rear-end opening 61B of an intake duct 60, which will be described later. The front portions of the condenser 52 and the condenser fan 53 are made of sheet metal and are housed in a box-shaped housing 58 that is attached upright to a base 55. The condenser 52 and the condenser fan 53 are arranged such that their vertical positions (vertical center positions P1, P2) are higher than the intake side openings 41 (vertical center position P3 of the plurality of intake side openings 41).

[0039] The condenser fan 53 has multiple blades that rotate when driven by a motor, thereby sending gas from the front to the rear. When the condenser fan 53 is driven, the condenser fan 53 draws gas into the machine room 13 through the intake-side opening 41 of the intake panel 40 and exhausts the gas to the outside through the exhaust-side opening 45 of the exhaust panel 44. Therefore, within the machine room 13, the intake panel 40 side (front side) is upwind and the exhaust panel 44 side (rear side) is downwind. The condenser 52, intake duct 60, and a gutter section 70 (described later) are positioned upwind of the condenser fan 53. On the other hand, the compressor 51 is positioned downwind of the condenser fan 53.

[0040] The machine room 13 is a plate-shaped member whose surface extends in the front-to-back and left-to-right directions, and is equipped with a base (bottom wall portion) 55 on which the compressor 51, condenser fan 53, and condenser 52 are placed, an intake duct 60 which is provided between the intake panel 40 and the condenser 52 and passes the gas drawn in from the intake side opening 41 toward the condenser 52, and a control unit 56 which is provided between the intake duct 60 and the upper panel 48 and controls each part.

The second partition wall portion 57 includes an upright plate portion 57A that rises from the base 55 and has a plate surface that extends in the left-right and up-down directions, a bridging plate portion 57B that connects the upper end of the upright plate portion 57A and the storage portion 58 in a bridging manner and has a plate surface that extends in the front-rear and left-right directions, an inclined plate portion 57C that rises from the base 55 and extends in a right-rear direction (diagonal direction) from the right end of the upright plate portion 57A, and a rear plate portion 57D that rises from the base 55 and extends rearward from the rear end of the inclined plate portion 57C. As shown in Figure 7, the upright plate portion 57A, the inclined plate portion 57C, and the rear plate portion 57D are arranged to cover the front (upwind side) and right side of the charging terminal 51A, which is the electrical connection part with other components in the compressor 51, and are attached to the base 55 in a manner separating the charging terminal 51A from the condenser fan 53.

[0042] 5 and 6, the control unit 56 is composed of a control board and the like provided inside a rectangular parallelepiped box (control box) with long sides extending in the left-right direction. An operation panel 56A is provided on the upper wall (upper wall of the control box) of the control unit 56. The operation panel 56A includes an operation unit for inputting signals to the control unit 56 and a display unit for displaying various values, and can be operated and viewed by removing the upper panel 48 from the machine room 13.

[0043] 5, 7, and 8, the intake duct 60 includes a rectangular tubular duct main body 61 extending in the front-rear direction, a rectangular rear end opening 61B that opens rearward at the rear end of the duct main body 61, a plurality of receiving portions 62 provided on the upper side of the rear end opening 61B, a standing wall portion 63 that rises downward from a front end opening 61A that opens forward at the front end of the duct main body 61, a right opening wall portion 64 that extends rightward from the front end opening 61A, a left opening wall portion 65 that extends leftward from the front end opening 61A, and an extending wall portion 66 that extends forward from the upper portion of the duct main body 61 beyond the standing wall portion 63, the right opening wall portion 64, and the left opening wall portion 65. A front end 66A of the extending wall portion 66 bends downward (toward the inside of the intake duct 60: the front end opening 61A side) and is close to (or abuts) the intake panel 40.

[0044] The duct main body 61 includes a bottom wall 61C that forms the bottom. The bottom wall 61C includes a rear bottom wall 61C1 whose plate surface extends in the front-rear and left-right directions, and a front bottom wall 61C2 (an inclined portion that inclines toward the gutter 70 as it approaches the intake-side opening 41 of the intake panel 40) that is located in front of the rear bottom wall 61C1 and slopes downward as it extends forward. The rear bottom wall 61C1 extends rearward beyond the receiving portion 62 and is adjacent to (or abuts against) a filter disposed in front of the condenser 52. The front end of the front bottom wall 61C2 is continuous with the upright wall 63.

[0045] The right opening wall 64 has a rectangular opening 64A for a power switch. As shown in FIGS. 7 and 8 , a power switch 59 electrically connected to the control unit 56 via electrical wiring is attached to the power switch opening 64A in a manner that exposes it forward. As shown in FIG. 7 , a space S1 on the side of the duct main body 61 is a space partitioned by the duct main body 61, the upper portion 23A of the right side panel 23, the left side panel 43, and the upper panel 48, and is separated from the space between the intake panel 40 and the condenser 52 (a space including the space inside the intake duct 60 and the space between the intake duct 60 and the intake panel 40). According to the present technology, water is prevented from entering the space S1, and electronic devices, various electrical wiring, and the like can be installed in the space S1.

[0046] As shown in FIG. 5, a bent plate portion 58A, which is a plate-like portion bent like a crank, is attached to the upper right portion of the accommodation portion 58. The control portion 56 is connected to the upper right portion of the bent plate portion 58A. The tip portion 58A1 of the bent plate portion 58A is inserted into a plurality of receiving portions 62 of the intake duct 60. The receiving portions 62 have a concave shape formed by folding back a metal plate. The intake duct 60 is attached to the accommodation portion 58 by inserting the tip portion 58A1 into the receiving portions 62, so that the intake duct 60 can be easily attached and detached when the intake panel 40 is removed.

[0047] As shown in Fig. 5, a space S2 with a predetermined gap is provided between the intake panel 40 and the intake duct 60. Also, as shown in Figs. 5 and 8, a gutter section 70 is provided between the intake panel 40 and the intake duct 60 (between the intake panel 40 and the condenser 52) at a position below the intake-side opening 41. The gutter section 70 extends in a shape that slopes upward (sloping downward toward the right) toward the inlet 26A of the first drainage channel 26. In the machine room 13, a wall section that is located above the gutter section 70 and faces the intake panel 40 (a wall section located rearward of the intake panel 40) is defined as an opposing wall section 67.

[0059] 12, 14, and 15, the opening-side first extending portion 124 includes an elongated plate-like extending main body portion 136 whose plate surface extends horizontally and whose long sides extend in the left-right direction (extending toward the sides of the opening 20), a rising portion 137 rising from the front end of the extending main body portion 136, and rising portions 138, 138 rising downward from both left and right end portions (side end portions) of the extending main body portion 136 and overlapping with the upper ends of the opening-side second extending portions 126, 127. As shown in FIG. 12, the rising portion 137 is the front end portion of the opening-side first extending portion 124, and is located between the packing 150 and the door-side first extending portion 104 and forward of the rear end portion 104A of the door-side first extending portion 104 when the door 22 is in the closed state.

[0060] 11 and 12, an upper packing 152 is provided between the packing 150 and the first door-side extension 104, with its front end attached to the inner wall frame portion 102A. The upper packing 152 extends in the left-right direction (the direction toward the front of the paper in FIG. 12), with its upper end abutting the first door-side extension 104, its right end abutting the second door-side extension 106 on the right side, its left end abutting the second door-side extension 107 on the left side, and its rear end abutting the rising portion 137 when the door 22 is in the closed state. The upper packing 152 can be made of a material that is softer (has a smaller elastic modulus) than the packing 150 so as not to hinder the magnet 151 of the packing 150 from attracting the frame plate portion 131 (opposing portion 120) etc. With this configuration, the upper gasket 152 can prevent water accumulated in the extension main body portion 136 from flowing over the rising portion 137 and accumulating on the gasket 150. If water accumulates on 150, the water accumulated on 150 may enter the storage chamber 14 when the door 22 is opened, and the stored items and the cooler (evaporator) 35 may become wet and freeze.

[0061] 11 and 12, when the door 22 is in the closed state, the front end 125A of the opening-side third extending portion 125 is located between the packing 150 and the door-side third extending portion 105 and forward of the rear end 105A of the door-side third extending portion 105. Note that one frame piece portion 132 is attached to the frame plate portion 131 so that the opening-side third extending portion 125 is located above the door-side third extending portion 105 of the upper door 22 of the two vertically adjacent doors 22, and the opening-side first extending portion 124 is located below the door-side first extending portion 104 of the lower door 22 of the two vertically adjacent doors 22.

[0063] 13, 16, and 17, opening 20 is provided with a key unit 140 that locks (locks) door 22 so that door 22 does not change from a closed state to an open state of opening 20. Key unit 140 is provided with a solenoid lock 141, a first cover part 142 located in front of solenoid lock 141, a second cover part (left opening-side second extension part) 127 that covers the right side and front side of first cover part 142, and a hole-shaped inserted part 147 that penetrates first cover part 142 and second cover part 127 in the front-rear direction and leads to the inside of solenoid lock 141.

[0064] 17, the door 22 has a plate-shaped insertion portion 109 extending rearward from the inner wall frame portion 102A on the left end portion 100D side of the main body portion 100. When the door 22 is changed from the open state to the closed state, the insertion portion 109 is inserted into the insertion portion 147. With the insertion portion 109 inserted into the insertion portion 147, the key portion 140 uses the solenoid lock 141 to restrict (fix) the displacement of the insertion portion 147, thereby locking the door 22. As shown in FIGS. 2 and 9, the door 22 has a cylindrical light guide 110 provided to the left of the handle portion 108 and penetrating the main body portion 100 from front to rear. The light guide 110 is configured to guide light emitted from a light source (not shown) such as an LED provided in the key unit 140 forward and emit it in front of the door 22 when the door 22 is locked or unlocked using the key unit 140.

[0065] 16 and 17, the first cover part 142 is box-shaped and opens to the rear, with its long sides extending in the vertical direction. An elastic, soft seal packing 148 is provided inside the first cover part 142 (between the first cover part 142 and the opposing part 120). The seal packing 148 abuts against the opposing part 120. The first cover part 142 and the second cover part 127 are attached to the opposing part 120 by threaded engagement with screws 149. The seal packing 148 prevents water from entering between the first cover part 142 and the second cover part 127 and the opposing part 120.

[0066] The second cover portion (left-side opening-side second extension portion) 127 extends forward from the opposing portion 120 and includes a plate-shaped first plate portion 144 with its long sides extending in the vertical direction, and a plate-shaped second plate portion 145 extending leftward from the front end of the first plate portion 144 with its long sides extending in the vertical direction, forming an L-shape when viewed from above. The second plate portion 145 is the front end portion of the second cover portion 127 and constitutes a part (front end portion) of the key portion 140. When the door 22 is in the closed state, the second cover portion 127 has its front end portion, the second plate portion 145, between the packing 150 and the left-side door-side second extension portion 107, It is located forward of the rear end portion 107A of the door-side second extending portion 107.

[0067] Next, the effects of this embodiment will be described. In this embodiment, the box 12 has an opening 20 that opens forward and can store items inside, and a door 22 that opens and closes the opening 20. The door 22 includes a main body 100, a packing 150 that is provided on the main body 100 and abuts against the opening 20 when the door 22 closes the opening 20, and door-side extensions 104, 105, 106, and 107 that are arranged closer to the end of the main body 100 than the packing 150 and extend rearward from the main body 100. When the opening 20 is closed, the box 12 has a door 22 that opens and closes the opening 20. 0, and opening-side extending portions 124, 125, 126, 127 extending forward from the facing portion 120, and front end portions 124A, 125A, 126A, 127A of the opening-side extending portions 124, 125, 126, 127 are located between the gasket 150 and the door-side extending portions 104, 105, 106, 107 and forward of rear end portions 104A, 105A, 106A, 107A of the door-side extending portions 104, 105, 106, 107 in the closed state.

[0068] In such a refrigerated storage cabinet 10, when the door 22 is in a closed state with the opening 20 closed, the door-side extensions 104, 105, 106, and 107 extending rearward from the main body 100 are disposed closer to the end of the main body 100 than the packing 150 of the door 22. Further, front ends 124A, 125A, 126A, and 127A of the opening-side extensions 124, 125, 126, and 127 extending forward from the opposing portion 120 are located between the packing 150 and the door-side extensions 104, 105, 106, and 107, and further forward than rear ends 104A, 105A, 106A, and 107A of the door-side extensions 104, 105, 106, and 107. Therefore, even if water splashes on the refrigerated storage cabinet 10 and moves between the door 22 and the box body 12, the water will not move toward the gasket 150 unless it passes over the rear ends 104A, 105A, 106A, 107A of the door-side extensions 104, 105, 106, 107, and even if the water does pass over the rear ends 104A, 105A, 106A, 107A, its front ends 124A, 125A, 126A, 127A will hit the opening extensions that are located between the gasket 150 and the door-side extensions 104, 105, 106, 107 and forward of the rear ends 104A, 105A, 106A, 107A of the door-side extensions 104, 105, 106, 107, thereby preventing the water from splashing directly on the gasket 150. This makes it possible to prevent water from entering the box body 12 through the gap between the opening 20 and the packing 150.

[0069] The door side extension portions 104, 105, 106, 107 include a door side first extension portion 104 that is located closer to the upper end of the main body portion 100 than the packing 150, and the opening side extension portions 124, 125, 126, 127 include an opening side first extension portion 124 whose front end portion 124A is located between the packing 150 and the door side first extension portion 104 when in the closed state, and the opening side first extension portion 124 includes an extension main body portion 136 that extends toward the side of the opening 20, and a rising portion 137 that is located forward of the rear end portion 104A of the door side first extension portion 104 and rises from the extension main body portion 136.

[0070] With this type of refrigerated storage cabinet 10, even if water gets on the refrigerated storage cabinet 10, the water can drip from the rear end 104A of the door-side first extending portion 104 onto the extending main body portion 136 of the opening-side first extending portion 124 and be received therein. The water received by the extending main body portion 136 can be blocked by the rising portion 137, thereby preventing the water from moving toward the packing 150. Furthermore, because the extending main body portion 136 extends toward the side of the opening 20, the water received by the extending main body portion 136 can be drained toward the side of the opening 20.

[0071] The door side extension portions 104, 105, 106, 107 include door side second extension portions 106, 107 that are located closer to the side end of the main body portion 100 than the gasket 150, and the opening side extension portions 124, 125, 126, 127 include opening side second extension portions 126, 127 whose front ends 126A, 127A are located between the gasket 150 and the door side second extension portions 106, 107 when in the closed state, and the opening side first extension portion 124 has a rising portion 138 that extends downward from the side end of the extension main body portion 136 and overlaps with the upper ends of the opening side second extension portions 126, 127.

[0072] With this cooling storage cabinet 10, water that runs down the side of the cooling storage cabinet 10 or that splashes from the side is directed against the opening-side second extending portions 126, 127, thereby preventing the water from splashing directly onto the packing 150. In addition, water that is received by the extending main body portion 136 of the opening-side first extending portion 124 and moves to the side can be smoothly conveyed by the rising portion 138 to the opening-side second extending portions 126, 127 and drained.

[0073] The opening 20 is provided with a key portion 140 that locks the door 22 so that the door 22 does not change from a closed state to an open state when the opening 20 is opened, and the door side extension portions 104, 105, 106, 107 include a left door side second extension portion 107 that is located closer to the lateral end of the main body portion 100 than the packing 150, and the opening side extension portions 124, 125, 126, 127 include a left opening side second extension portion 127 whose front end portion 127A is located between the packing 150 and the left door side second extension portion 107 and that forms part of the key portion 140.

[0074] According to such a cooling storehouse 10, the functional member (key part 140) having the function of locking the door 22 can also be used, making it possible to prevent water from being splashed directly onto the packing 150.

[0075] The door-side extending portions 104, 105, 106, 107 include a door-side first extending portion 104 located closer to the upper end 100A of the main body 100 than the packing 150, door-side second extending portions 106, 107 located closer to the side ends 100C, 100D of the main body 100 than the packing 150, and a door-side third extending portion 105 located closer to the lower end 100B of the main body 100 than the packing 150. 127 includes an opening-side first extension portion 124 whose front end portion 124A is located between the packing 150 and the door-side first extension portion 104 in the closed state, opening-side second extension portions 126, 127 whose front end portions 126A, 127A are located between the packing 150 and the door-side second extension portions 106, 107, and an opening-side third extension portion 125 whose front end portion 125A is located between the packing 150 and the door-side third extension portion 105.

[0076] According to such a refrigerated storehouse 10, it is possible to prevent water from being directly splashed on the packing 150 around the entire periphery of the door 22.

[0077] The box body 12 has a hinge portion 21 to which a door 22 is attached in a manner that allows it to rotate, and the door 22 has a partition portion 103 that separates a hollow internal space and a hole portion 100B1 provided inside the door 22 on the hinge portion 21 side of the partition portion 103.

[0078] In this refrigerated storage cabinet 10, even if water enters the interior of the door 22 from the hinge 21 side, the partition wall 103 can prevent the water from moving into space S3 of the interior space of the door 22 other than the hinge 21 side. Furthermore, water that has entered space S4 of the interior space of the door 22 on the hinge 21 side can be drained through the hole 100B1. This is preferable because it can prevent the insulating material filled in space S3 of the interior space of the door 22 other than the hinge 21 side from getting wet.

[0079] The box body 12 has a drainage channel 26 extending in the vertical direction, and the cooling storage facility 10 has a machine room 13 provided above the box body 12, and the machine room 13 has an intake panel 40 having an intake side opening 41, a condenser 52 provided on the indoor side of the intake panel 40, and a condenser 52 fan that is driven by itself to draw in outside gas from the intake side opening 41 and cool at least the condenser 52, and between the intake panel 40 and the condenser 52 there is provided a gutter section 70 that is located below the intake side opening 41 and extends at an angle upward toward the drainage channel 26.

[0080] With this type of refrigerated storage cabinet 10, water that enters the interior of the machine room 13 from the intake side opening 41 of the intake panel 40 is received by the gutter section 70, which is located below the intake side opening 41 between the intake panel 40 and the condenser 52, and can be drained toward the drainage channel 26 by the gutter section 70.
