Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the configuration disclosed in Patent Document 1, when water such as rainwater hits the cooling storage refrigerator, there is a risk that water may enter the upper machine room from the upstream louver, the downstream louver, etc. If a control unit, electrical wiring, etc. are provided in the upper machine room, it is conceivable that the control unit may malfunction or electric leakage may occur from the connection part of the electrical wiring due to the water that has entered the upper machine room. Further, when the blower is driven, water easily enters the upper machine room together with the intake air from the upstream louver, and the water that has entered the upper machine room is diffused by the blower, which further raises concerns about the malfunction of the control unit, etc.

[0005] Furthermore, in the case where a cooling refrigerator is provided with a door that can open and close inside the heat insulation box, or a cooler that can cool the stored items stored inside the heat insulation box is provided inside the heat insulation box, if water such as rainwater gets on the cooling refrigerator and water enters the heat insulation box from between the heat insulation box body and the door, etc., there is a risk that the stored items and the cooler will freeze and the cooling performance of the cooling refrigerator will deteriorate.

[0006] The present disclosure has been completed based on the above circumstances, and one of its purposes is to provide a cooling refrigerator that can drain water well even when water enters inside. Another purpose is to provide a cooling refrigerator in which it is difficult for water to enter inside.

Means for Solving the Problems

[0007] The present disclosure includes a box body capable of storing stored items inside, and a machine room provided above the box body. The box body includes a first drain channel extending in the vertical direction. The machine room includes an intake panel having an opening, a condenser provided on the indoor side of the intake panel, and a condenser fan that sucks gas from the outside through the opening by driving itself to cool at least the condenser. Between the intake panel and the condenser, a gutter portion is provided that is located below the opening and extends in a shape inclined upward toward the first drain channel. It is a cooling refrigerator.

[0008] According to such a cooling refrigerator, water that has entered the inside of the machine room from the opening of the intake panel can be received by the gutter portion located below the opening between the intake panel and the condenser, and can be drained by the gutter portion toward the first drain channel. And by allowing water to pass through the first drain channel extending vertically, it is possible to provide a cooling refrigerator that can drain water well toward the lower part of the box body.

[0009] In the above configuration, the machine room may include a side panel attached to a side end portion of the intake panel, an intake duct provided between the intake panel and the condenser and passing the gas sucked from the opening toward the condenser, and a first partition portion separating the side end portion of the intake panel and the intake duct.

[0010] According to such a cooling refrigerator, the first partition portion can suppress water from entering the inside of the machine room from between the side end portion of the intake panel and the side panel (the portion where the panels are attached) into the intake duct or the peripheral portion of the condenser. When electrical wiring or the like is arranged in the peripheral portion of the condenser, it is possible to suppress the electrical wiring or the like from getting wet.

[0011] In the above configuration, the first partition portion may be located above the gutter portion and inside the side end portion of the gutter portion. According to such a cooling refrigerator, the water flowing down the first partition portion can be dropped into the gutter portion and drained toward the first drain passage.

[0012] In the above configuration, the machine room is provided between the intake panel and the condenser, and includes an intake duct that passes the gas sucked from the opening toward the condenser. The condenser is arranged at a position higher in the vertical direction than the opening, and the gutter portion may be provided between the intake panel and the intake duct.

[0013] According to such a cooling refrigerator, while taking in outdoor gas (sometimes referred to as outside air) from the opening of the intake panel toward the condenser side, the water entering the room from the opening can be successfully dropped into the gutter portion.

[0014] In the above configuration, the intake duct may include an inclined portion that inclines toward the gutter portion toward the opening side. According to such a cooling refrigerator, when the water that has entered the room from the intake panel adheres to the intake duct, the water can flow along the inclined portion and flow into the gutter portion.

[0015] In the above configuration, the machine room may be located above the gutter portion and include a facing portion facing the intake panel and a separation portion provided in the facing portion and having a lower end separated from the facing portion toward the intake panel side.

[0016] According to such a cooling refrigerator, the water entering from the opening of the intake panel can be applied to the opposing portion and dropped into the trough portion. Further, the water passing through the opposing portion can be dripped into the trough portion by the separation portion, and can be properly drained.

[0017] In the above configuration, the box body may include a second drain passage extending in the vertical direction, the machine room may include an exhaust panel having an exhaust-side opening, and the indoor gas may be exhausted from the exhaust-side opening by driving the condenser fan. The exhaust panel may be located below the exhaust-side opening and may include an exhaust-side trough portion extending toward the second drain passage.

[0018] According to such a cooling refrigerator, the water entering the interior of the machine room from the exhaust-side opening of the exhaust panel can be received by the exhaust-side trough portion located below the exhaust-side opening, and can be flowed toward the second drain passage by the exhaust-side trough portion. And, by allowing water to pass through the second drain passage extending vertically, a cooling refrigerator that can be properly drained downward of the box body can be provided.

[0019] In the above configuration, the machine room may include a compressor disposed at a position downstream of the condenser fan, and the cooling refrigerator may include a second partition portion that separates the condenser fan and the charging terminal of the compressor. According to such a cooling refrigerator, even if water enters the room, the second partition portion can suppress the charging terminal from getting wet.

[0020] In the above configuration, the box body may include a box body opening, a hinge portion provided at the box body opening, and a door that rotates about the hinge portion to open and close the box body opening, and the first drain passage may be provided on the side of the hinge portion.

[0021] According to such a cooling refrigerator, since the first drain passage is provided on the side of the hinge portion, drainage from the machine room can be performed while avoiding the end portion on the side opposite to the hinge portion of the door and the end portion side that moves away from or approaches the box body opening as the door opens and closes. Thereby, it is possible to suppress water from entering the box body from between the box body and the door.

Effects of the Invention

[0022] According to the present disclosure, it becomes possible to provide a cooling refrigerator that can drain water well even when water enters inside. In addition, it becomes possible to provide a cooling refrigerator in which water hardly enters inside.

[0024] <Embodiment> Embodiments of the present disclosure will be described with reference to FIGS. 1 to 12. In this embodiment, as a cooling storage, a locker-type cooling storage 10 will be exemplified. In each figure, the arrow direction L is the left direction, the arrow direction R is the right direction, the arrow direction F is the front direction, the arrow direction B is the rear direction, the arrow direction U is the upper direction, and the arrow direction D is the lower direction for explanation.

[0025] As shown in FIG. 1, a plurality of cooling storages 10 are arranged adjacent to each other together with a cooling storage 11 provided with an operation terminal 80 to form a cooling storage group 1. The cooling storage 10 is installed, for example, at the storefront of a store or inside a shopping mall, and can store stored items such as beverages, foods, and medicines while cooling them and accommodate them in a locked state. The cooling storage 10 is used for a user (e.g., a purchaser) to receive the luggage stored by a provider (e.g., a store clerk or a delivery person), but the use is not limited. For example, it may be used by a user to temporarily cool and store luggage. Also, depending on the use and installation location, only one cooling storage 10 may be installed and used instead of a plurality of them.

[0026] The operation terminal 80 provided in the cooling storage 11 is an information terminal including at least one of input means 80A such as an operation panel or reading means 80B such as a barcode reader, and known terminals such as a tablet terminal or a computer are used. The user can unlock or lock the locking device for locking the door 22 by inputting a password on the operation panel or having the barcode reader read a two-dimensional barcode. The operation terminal 80 may be installed around separately from the cooling storage 10, and is not required when the locking device is not an electronic lock.

[0027] As shown in FIGS. 2 and 3, the cooling refrigerator 10 is generally vertically long and substantially rectangular parallelepiped in shape.

The provider and the user can take in and out the stored items inside the box body 12 by opening and closing the door 22.

[0028] The box body 12 is surrounded by plate-like side panels 23 and 24 provided on the left and right sides and having plate surfaces extending in the front-rear direction and the up-down direction, and a plate-like back panel 25 provided on the rear side and having a plate surface extending in the left-right direction and the up-down direction. The door 22 and each of the panels 23, 24, and 25 are each of a double structure composed of an outer wall and an inner wall attached to the inner side of the outer wall, and a heat insulating material such as urethane foam is filled between the outer wall and the inner wall. Incidentally, the upper portion 23A of the right side panel 23 constitutes the right side wall portion of the machine room 13.

[0029] The box body 12 is provided with a first drain channel 26, a second drain channel 27, and a third drain channel 28 that extend in the vertical direction. The first drain channel 26 is provided between the right end portion of the door 22 and the right side panel 23 and to the right of the hinge portion 21 (lateral to the hinge portion 21), forming the right front corner portion of the box body 12, and has a tubular shape with a rectangular cross-section. A gap is provided between the first drain channel 26, the right end portion of the door 22, and the hinge portion 21 (see Fig. 10). The upper end portion of the first drain channel 26 is a water inlet 26A having a rectangular frame shape when viewed from above with the front-rear direction as the long side. The second drain channel 27 is provided between the right side panel 23 and the back panel 25, forming the right rear corner portion of the box body 12, and like the first drain channel 26, has a tubular shape with a rectangular cross-section. The third drain channel 28 is provided between the left side panel 24 and the back panel 25, forming the left rear corner portion of the box body 12, and like the first drain channel 26 and the second drain channel 27, has a tubular shape with a rectangular cross-section. Each of the drain channels 26, 27, 28 can direct the water flowing from the machine room 13 downward in the box body 12 and drain it to the outside of the cooling storage 10.

[0030] As shown in Fig. 4, inside the box body 12 (hereinafter sometimes referred to as the storage room 14), there are provided a cooler chamber 30 in which a cooler (evaporator) 35, a circulation fan, etc. are accommodated, and a plurality of shelf plates 32 that partition the storage room 14 into a plurality of spaces 14A arranged vertically. Inside the right side panel 23, a hollow right duct 31 extending vertically is provided. Inside the left side panel 24, a hollow left duct (not shown) extending vertically is provided in the same manner as the right duct 31. The right duct 31 is provided with a plurality of hole portions 31A. The left duct is provided with a plurality of hole portions (not shown) in the same manner as the right duct 31.

[0031] In front of each shelf board 32, a rectangular columnar frame 29 extending in the left-right direction is provided. The frame 29 is filled with a heat insulating material such as urethane foam inside, and is a portion where the upper and lower ends of the packing provided on the inner surface side of the door 22 abut. The plurality of doors 22 are attached to each hinge portion 21 so that each of the spaces 14A partitioned by the plurality of shelf boards 32 can be opened and closed.

[0032] When the circulation fan operates, the gas in the storage chamber 14 flows into the left duct from the hole of the left duct, rises in the left duct, and flows into the cooler chamber 30. The gas flowing into the cooler chamber 30 is cooled by heat exchange in the process of passing through the cooler 35 and becomes cold air. This cold air flows out from the cooler chamber 30 into the right duct 31, descends in the right duct 31, and is blown out from the plurality of holes 31A into the storage chamber 14. In this way, the gas in the storage chamber 14 is cooled while circulating.

[0033] As shown in FIGS. 1 and 2, the machine room 13 has a plurality of openings 41, a plate-shaped intake panel 40 constituting the front wall portion, an upper portion 23A of a plate-shaped side panel 23 constituting the right wall portion, a plate-shaped side panel 43 constituting the left wall portion, a plurality of openings (exhaust side openings) 45, and a plate-shaped exhaust panel 44 constituting the rear wall portion, and a plate-shaped upper panel (ceiling) 48 constituting the upper wall portion.

[0059] According to such a cooling refrigerator 10, the water entering from the opening 41 of the intake panel 40 can be applied to the opposing portion 67 and dropped onto the gutter portion 70. Further, the water passing through the opposing portion 67 can be dripped onto the gutter portion 70 by the spaced portions 67A, 67B and can be successfully drained.

[0060] The box body 12 is provided with a second drain passage 27 extending in the vertical direction, the machine room 13 is provided with an exhaust panel 44 having an exhaust side opening 45, and is configured to exhaust indoor gas from the exhaust side opening 45 by driving the condenser fan 53. The exhaust panel 44 is located below the exhaust side opening 45 and is provided with an exhaust side gutter portion 44C extending toward the second drain passage 27.

[0061] According to such a cooling refrigerator 10, the water that has entered the interior of the machine room 13 from the exhaust side opening 45 of the exhaust panel 44 can be received by the exhaust side gutter portion 44C located below the exhaust side opening 45, and can be made to flow toward the second drain passage 27 by the exhaust side gutter portion 44C. Then, by allowing water to pass through the second drain passage 27 extending vertically, it is possible to provide a cooling refrigerator 10 that can be successfully drained downward of the box body 12.

[0062] The machinery room 13 is provided with a compressor 51 arranged at a position downstream of the condenser fan 53, and the cooling storage cabinet 10 is provided with a second partition portion 57 that separates the condenser fan 53 from the charging terminal 51A of the compressor 51. According to such a cooling storage cabinet 10, even if water enters the room by chance, the second partition portion 57 can suppress the charging terminal 51A from getting wet.

[0063] The box body 12 includes a box body opening 20, a hinge portion 21 provided at the box body opening 20, and a door 22 that rotates about the hinge portion 21 to open and close the box body opening 20. The first drain channel 26 is provided on the side of the hinge portion 21.

[0064] According to such a cooling storage cabinet 10, since the first drain channel 26 is provided on the side of the hinge portion 21, drainage from the machinery room 13 can be performed while avoiding the end portion on the side opposite to the hinge portion 21 of the door 22 and away from or approaching the box body opening 20 as the door 22 opens and closes. Thereby, it is possible to suppress water from entering the box body 12 from between the box body 12 and the door 22.
