Description

This disclosure relates to a cooling storage facility.

Conventionally, a cooling storage unit described in Patent Document 1 is known. Specifically, the cooling storage unit (refrigerator) described in Patent Document 1 comprises an insulated box body and an upper machine room provided on top of the insulated box body, and the upper machine room is provided with, in order from the windward side, an upwind louver, an air-cooled condenser, a blower, a compressor, and a leeward louver. By driving the blower, the windward side of the upper machine room becomes negative pressure, 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 discharged outside the upper machine room through the leeward louver.

JP 2017-203602 A

However, with the configuration disclosed in Patent Document 1, if rainwater or other water gets on the cooling storage, 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 provided in the upper machine room, water that enters the upper machine room may cause the control unit to malfunction or cause a current leak from the electrical wiring connections. In addition, when the blower is driven, water is more likely to enter the upper machine room along with the air drawn in from the windward louvers, and water that has entered the upper machine room is dispersed by the blower, raising further concerns about the failure of the control unit, etc.

Furthermore, if the cooling storage unit has a door that can be opened and closed inside the insulated box, or if a cooler capable of cooling the items stored inside the insulated box is installed inside the insulated box, if rainwater or other water gets on the cooling storage unit and enters the insulated box through a gap between the insulated box and the door, the stored items or the cooler may freeze, which may reduce the cooling performance of the cooling storage unit.

This disclosure was completed based on the above circumstances, and one of its objectives is to provide a cooling storage unit that can drain water well even if water gets inside. Another objective is to provide a cooling storage unit that makes it difficult for water to get inside.

The present disclosure relates to a cooling storage facility that includes a box capable of storing items therein and a machine room provided above the box, the box having a first drainage channel extending in the vertical direction, the machine room including an intake panel having an opening, a condenser provided on the indoor side of the intake panel, and a condenser fan that is driven by itself to draw in outdoor gas from the opening and cool at least the condenser, and a gutter portion is provided between the intake panel and the condenser, located below the opening and extending at an angle toward the upper side of the first drainage channel.

With this type of cooling storage, water that enters the machine room through the opening in the intake panel is received by a gutter located below the opening between the intake panel and the condenser, and can then be channeled toward the first drainage channel by the gutter. As the water passes through the first drainage channel that extends vertically, a cooling storage can be provided that can be efficiently drained toward the bottom of the box body.

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

In this type of cooling storage, the first partition can prevent water from entering the intake duct or the area around the condenser inside the machine room from between the lateral end of the intake panel and the side panel (the area where the panels are attached). If electrical wiring, etc. is routed around the condenser, the electrical wiring, etc. can be prevented from getting wet.

In the above configuration, the first partition wall may be located above the gutter portion and inside the side end portion of the gutter portion. With such a cooling storage facility, water flowing down the first partition wall can be dropped into the gutter portion and drained toward the first drainage channel.

In the above configuration, the machine room may be provided with an intake duct between the intake panel and the condenser, which passes the gas sucked in from the opening toward the condenser, the condenser may be positioned higher in the vertical direction than the opening, and the gutter may be provided between the intake panel and the intake duct.

This type of cooling storage unit allows outdoor gas (sometimes called outside air) to be sucked up through the opening in the intake panel toward the condenser, while water that enters the room through the opening can be efficiently dropped into the gutter.

In the above configuration, the intake duct may have an inclined portion that is inclined toward the gutter portion as it approaches the opening. With this type of cooling storage, if water that has entered the room through the intake panel adheres to the intake duct, the water can flow down the inclined portion into the gutter portion.

In the above configuration, the machine room may have a facing portion located above the gutter portion and facing the intake panel, and a separating portion provided on the facing portion, the lower end of which is separated from the facing portion toward the intake panel.

With this type of cooling storage, water entering through the opening of the intake panel can hit the opposing part and fall into the gutter. Also, water running down the opposing part can be made to drip into the gutter by the separating part, allowing it to be efficiently drained.

In the above configuration, the box body has a second drainage channel extending in the vertical direction, the machine room has an exhaust panel with an exhaust side opening, and the condenser fan is driven to exhaust gas from the exhaust side opening, and the exhaust panel may have an exhaust side gutter portion located below the exhaust side opening and extending toward the second drainage channel.

With this type of cooling storage, water that enters the machine room from the exhaust side opening of the exhaust panel is received by the exhaust side gutter located below the exhaust side opening, and can be diverted toward the second drainage channel by the exhaust side gutter. As the water passes through the second drainage channel that extends vertically, a cooling storage can be provided that can be efficiently drained toward the bottom of the box body.

In the above configuration, the machine room may include a compressor disposed downwind of the condenser fan, and the cooling storage may include a second partition wall that separates the condenser fan from the charging terminal of the compressor. With such a cooling storage, even if water gets into the room, the second partition wall can prevent the charging terminal from getting wet.

In the above configuration, the box body includes a box body opening, a hinge portion provided at the box body opening, and a door that rotates around the hinge portion as an axis to open and close the box body opening, and the first drainage channel may be provided to the side of the hinge portion.

In this type of cooling storage, the first drainage channel is provided to the side of the hinge section, so water can be drained from the machine room while avoiding the end of the door opposite the hinge section, which is close to or away from the opening of the box as the door is opened and closed. This makes it possible to prevent water from entering the box from between the box and the door.

According to the present disclosure, it is possible to provide a cooling storage unit that can effectively drain water even if water gets inside. It is also possible to provide a cooling storage unit that is less likely to allow water to get inside.

<Embodiment>
An embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 12. In this embodiment, a locker-type cooling storage unit 10 is exemplified as a cooling storage unit. 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 up direction, and the arrow direction D is the down direction.

As shown in FIG. 1, multiple cooling storage units 10 are arranged adjacent to each other, with cooling storage units 11 each equipped with an operation terminal 80, to form a cooling storage unit group 1. The cooling storage units 10 are installed, for example, in front of a store or in a shopping mall, and can store beverages, food, medicines, and other stored items in a locked state while keeping them cool. The cooling storage units 10 are used by users (e.g., purchasers) to receive packages stored by providers (e.g., store clerks or delivery staff), but the uses are not limited. For example, the cooling storage units 10 may be used by users to temporarily store packages in a cooled state. Also, depending on the use and installation location, only one cooling storage unit 10 may be installed and used, rather than multiple units.

The operation terminal 80 provided in the cooling storage facility 11 is an information terminal equipped with at least one of an input means 80A such as an operation panel or a reading means 80B such as a barcode reader, and may be a known terminal such as a tablet terminal or a computer. A user can unlock or lock the locking device that locks the door 22 by inputting a password into the operation panel or having a barcode reader read a two-dimensional barcode. The operation terminal 80 may be installed in the vicinity as a separate entity from the cooling storage facility 10, and is not required if the locking device is not an electronic lock.

As shown in Figures 2 and 3, the cooling storage facility 10 has an overall shape of a vertically long rectangular parallelepiped. The cooling storage facility 10 comprises a box body 12 capable of storing items inside, and a machine room 13 provided above the box body. The box body 12 comprises a box body opening 20 (see Figure 4) that opens to the front, multiple hinge parts 21 provided at the right front end part of the box body opening 20, and multiple doors 22 that rotate forward about the hinge parts 21 to open and close the box body opening 20. The provider and user can put items in and take them out of the box body 12 by opening and closing the doors 22.

The box 12 is surrounded by plate-shaped side panels 23, 24 on the left and right sides, with plate surfaces extending in the front-rear and up-down directions, and a plate-shaped back panel 25 on the rear side, with plate surfaces extending in the left-right and up-down directions. The door 22 and each panel 23, 24, 25 each have 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 side wall of the machine room 13.

The box body 12 is provided with a first drainage channel 26, a second drainage channel 27, and a third drainage channel 28 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 section 21 (to the side of the hinge section 21), forming a right front corner of the box body 12, and has a cylindrical 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 section 21 (see FIG. 10). 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 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 has a cylindrical shape with a rectangular cross section like the first drainage channel 26. The third drainage channel 28 is provided between the left side panel 24 and the back panel 25, and forms the left rear corner of the box body 12. Like the first drainage channel 26 and the second drainage channel 27, the third drainage channel 28 has a cylindrical shape with a square cross section. Each drainage channel 26, 27, and 28 can direct water flowing from the machine room 13 downwards into the box body 12 and drain it to the outside of the cooling storage facility 10.

As shown in FIG. 4, the interior 14 of the box 12 (hereinafter sometimes referred to as the storage chamber 14) is provided with a cooler chamber 30 housing a cooler (evaporator) 35, a circulation fan, etc., and a plurality of shelves 32 that divide the storage chamber 14 into a plurality of spaces 14A arranged vertically. 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.

A square column-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 is the part that abuts the upper and lower ends of the packing provided on the inner side of the door 22. The multiple doors 22 are attached to each hinge portion 21 so that each of the spaces 14A partitioned by the multiple shelves 32 can be opened and closed.

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 inside 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 down inside the right duct 31, and is blown out of the multiple holes 31A into the storage chamber 14. In this way, the gas in the storage chamber 14 is cooled as it circulates.

With this cooling storage facility 10, water that has entered the inside of the machine room 13 from the exhaust side opening 45 of the exhaust panel 44 is received by the exhaust side gutter section 44C located below the exhaust side opening 45, and can be drained toward the second drainage channel 27 by the exhaust side gutter section 44C. Then, by passing through the second drainage channel 27 that extends vertically, a cooling storage facility 10 can be provided that can be efficiently drained toward the bottom of the box body 12.

The machine room 13 includes a compressor 51 that is located downwind of the condenser fan 53, and the cooling storage 10 includes a second partition 57 that separates the condenser fan 53 from the charging terminal 51A of the compressor 51. With this type of cooling storage 10, even if water gets inside the room, the second partition 57 can prevent the charging terminal 51A from getting wet.

The box body 12 has a box body opening 20, a hinge portion 21 provided at the box body opening 20, and a door 22 that rotates around the hinge portion 21 to open and close the box body opening 20, and the first drainage channel 26 is provided to the side of the hinge portion 21.

In this type of cooling storage 10, the first drainage channel 26 is provided to the side of the hinge portion 21, so that water can be drained from the machine room 13 by avoiding the end of the door 22 opposite the hinge portion 21, which is the end that moves away from or approaches the box opening 20 as the door 22 is opened and closed. This makes it possible to prevent water from entering the box 12 between the box 12 and the door 22.
