In a cooling storage having a structure that is movable with a plurality of wheels, such as the cooling storage described in the above patent document, the shelves placed in the storage chamber are likely to fluctuate due to the movement of the cooling storage. If the shelf board fluctuates, as described in Patent Document 1 above, the stored items on the shelf board may tip over, and the contents may spill or come into vigorous contact with the inside of the storage chamber. The inside of the storage chamber may be damaged.

The present invention has been made in view of such circumstances, and an object of the present invention is to suppress fluctuations in shelves placed in a storage chamber in a movable cooling storage.

In order to solve the above problems, the cooling storage of the present invention is used.
A cooling storage that is movable with a storage main body, a cooling device for cooling the inside of the storage main body, and a plurality of wheels arranged under the storage main body.
The storage main body has a storage room that opens forward and allows a plurality of shelves to be placed vertically arranged inside, and a machine room provided below the storage room.
The cooling device enters the storage room from the machine room, the cooler arranged at the upper part in the storage room, the machine room side unit arranged in the machine room and including at least a compressor and a condenser, and said. It has a refrigerant pipe that connects the cooler and the machine room side unit.
The refrigerant pipe is arranged so as to extend in the vertical direction along one side end portion of both side ends on the back surface of the storage chamber.
On the back of the storage room
A refrigerant pipe cover that covers the refrigerant pipe and extends in the vertical direction,
A ridge portion that extends in the vertical direction at a position separated from the refrigerant pipe cover and projects forward.
Is arranged,
The ridge portion and the refrigerant pipe cover are configured so that the protrusion heights from the back surface to the front of the storage chamber are the same.

For example, in a cooling storage having no ridge portion, the rear end of the shelf plate is supported by the refrigerant pipe cover only at one end in the width direction. If the width of the shelf board is small, the other end side in the width direction of the shelf board enters the rear, in other words, the shelf board rotates with the refrigerant pipe cover as a fulcrum. On the other hand, in the cooling storage having this configuration, the rear end of the shelf board placed in the storage chamber can be supported by two points, the refrigerant pipe cover and the ridge portion, and thus on the horizontal plane as described above. It is possible to suppress the fluctuation of the shelf board that rotates with.

In the above configuration, the cooling device is provided with a housing member attached to the ceiling surface of the storage chamber in a state of covering the cooler and air in the housing member provided in front of the cooler in the housing member. The housing member includes an internal fan for suction, and the housing member is shaped to form a gap between its rear end and the back surface of the storage chamber, and the gap is formed downward from the inside of the housing member. It is supposed to function as an air outlet for blowing out air, and the ridge portion may be hollow and extend below the shelf board placed on the lowermost stage.

The cooling storage with this configuration is limited to those in which the air circulation path in the storage chamber sucks in from the front side and blows out from the rear side at the upper part of the storage chamber, and a part of the blown cold air is used at the ridge. Then, it can be supplied to the bottom surface of the storage chamber, in other words, to the lower side of the shelf board placed on the bottom stage. Therefore, in the cooling storage having this configuration, the ridge portion can function not only as a stopper for the shelf board but also as an air duct, and the storage chamber can be efficiently cooled.

Further, in the above configuration, the ridge portion may be configured to be located at the center in the width direction in the storage chamber.

When the cold air is blown from the inside of the ridge to the bottom surface of the storage chamber, the cooling storage of this configuration can be blown to the center in the width direction, and the cold air can be flowed evenly to the left and right. Cooling can be performed more efficiently and evenly.

Further, in the above configuration, the housing member is assumed to function as a drain pan for receiving water dripping from the cooler, and the cooling storage is on the back side of the storage chamber in order to drain water in the housing member. A drainage pipe extending toward the inside of the wall portion of the wall portion may be provided, and the ridge portion and the drainage pipe may be arranged at positions where they do not overlap in the vertical direction.

In the cooling storage of this configuration, the cold air hits the drain pipe before the cold air is blown out from the inside of the housing member, but the drain pipe is arranged at a position shifted in the width direction from the ridge portion. Cold air can be reliably sent to the inside of the ridge.

Further, in the above configuration, a door rotatably provided around an axis extending along one side end portion on the front side of the storage main body and opening and closing the storage chamber is provided, and the back surface of the door is provided with a door. The door-side ridge portion that extends in the vertical direction and protrudes rearward can be formed.

In the cooling storage having this configuration, the presence of the door-side ridge portion can prevent the shelf board from coming into contact with the door body, and the amount of movement of the shelf board to the front side can be reduced. Further, in the cooling storage of this configuration, even if the shelf board is not sufficiently inserted into the storage room and protrudes forward, the door-side protrusion hits the shelf board when the door is closed. The shelves can be touched and pushed into the storage chamber. By pushing the shelf board into the storage chamber, a gap can be secured between the shelf board and the door body, and a cold air circulation path between the shelf board and the door can be surely secured.

According to the present invention, it is possible to suppress fluctuations in the shelves placed in the storage chamber in the movable cooling storage.

That is, by removing the front panel 16A and moving the slider 36 forward, it is possible to perform maintenance of the machine room side unit 30A and the like.

Further, in the machine room 16, on the left side of the machine room side unit 30A (on the left side of the machine room 16), immediately behind the front panel 16A, an electrical box for controlling the operation of each device provided in the cooling storage 10. 40 is provided. Behind the electrical box 40, a partition member 41 for partitioning a space having a rectangular parallelepiped shape is generally provided, and a drain for storing the internal drainage of the cooling storage 10 is stored in the space partitioned by the partition member 41. A tank 42 is provided. The space partitioned by the partition member 41 is open to the rear, and the drain tank 42 can be easily taken out from the rear side.

Next, the cooler 35 for which the description has been reserved, and the connection structure between the cooler 35 and the machine room side unit 30A will be described in detail. As shown in FIG. 3, the cooler 35 is fixed to the ceiling surface 15C of the storage chamber 15 in the storage main body 13. The above-mentioned refrigerant pipes 34A and 34B are bent at the rear end portion of the machine room 16 and extend upward to be connected to the cooler 35. More specifically, the refrigerant pipes 34A and 34B enter the storage chamber 15 from the machine room 16 and extend along the right side end portion of the back surface 15D of the storage chamber 15. As shown in FIGS. 2 and 5, the refrigerant pipes 34A and 34B are covered with a refrigerant pipe cover 50 attached along the right back corner in the storage chamber 15.

The connection portions of the cooler 35 and the refrigerant pipes 34A and 34B to the cooler 35 are covered with a housing member 51. The housing member 51 includes a metal spacer 51A attached to the ceiling surface 15C and a resin air duct 51B attached to the lower side of the spacer 51A. A cooler chamber 52 is formed between the housing member 51 and the ceiling surface 15C of the storage chamber 15. The air duct 51B of the housing member 51 is provided with an internal fan 53 in front of the cooler 35, and the air in the storage chamber 15 is sucked into the cooler chamber 52 by driving the internal fan 53. Will be done. Further, as shown in FIGS. 5 and 6, a gap 54 is formed between the rear end of the air duct 51B of the housing member 51 and the back surface 15D of the storage chamber 15, and the air duct 51B is sucked from the internal fan 53. The cold air generated by heat exchange while passing through the cooler 35 is blown downward from the gap 54. That is, the gap 54 serves as an outlet for the cooler chamber 52. From the above configuration, when the compressor 33, the condenser fan 32, and the internal fan 53 are driven, cold air is circulated and supplied from the cooler chamber 52 to the storage chamber 15.

The air duct 51B of the housing member 51 also functions as a drain pan. As shown in FIG. 3, the air duct 51B of the housing member 51 has a shape in which the bottom surface of the housing member 51 inclines downward as the bottom surface moves backward, and the water dripping on the bottom surface of the air duct 51B flows rearward. ing. A drain hose (drainage pipe) 60 is provided at the rear end of the air duct 51B. The drain hose 60 extends to the machine room 16 through the inside of the wall portion on the back surface 15D side of the storage main body 13. Further, the drain hose 60 penetrates the partition member 41 and its tip is positioned on the drain tank 42 so that the drainage discharged from the cooler chamber 52 collects in the drain tank 42. In the present embodiment, the frost formed on the cooler 35 by the cooling operation is melted by appropriately stopping the cooling operation. The defrosting method is not limited to such off-cycle defrosting, and a defrosting heater may be attached to the cooler 35 and the cooler 35 may be energized to melt it. Further, even when the cooling storage 10 is moved in a state where the power cord is unplugged and the power supply is stopped, the frost formation may be melted by stopping the cooling operation, and defrosted water may be generated.

Next, the features of the present embodiment will be described in detail. As shown in FIG. 2, in the cooling storage 10, a stopper member 70 as a ridge portion extending in the vertical direction and projecting forward is fixed to the back surface 15D of the storage chamber 15. As shown in FIG. 7, the stopper member 70 has a protrusion height H from the back surface 15D to the front that coincides with the protrusion height of the refrigerant pipe cover 50. For example, if the stopper member 70 does not exist, the rear end of the tray 22 is supported by the refrigerant pipe cover 50 only at one end (right end) in the width direction. Then, if there is a margin in the width direction when the tray 22 is placed on the pair of tray guides 21, the other end side (left side) in the width direction of the tray 22 may enter the rear, in other words. The tray 22 rotates with the refrigerant pipe cover 50 as a fulcrum. On the other hand, in the cooling storage 10, as shown in FIG. 7, the rear end of the tray 22 can be supported by two points, the refrigerant pipe cover 50 and the stopper member 70, so that the tray 22 can be supported on the horizontal plane as described above. It is possible to suppress fluctuations in the tray 22 that rotates in.

As shown in FIG. 2, the stopper member 70 extends from the vicinity of the rear end (outlet 54) of the air duct 51B of the housing member 51 to substantially the same height as the lowermost tray guide 21. That is, the stopper member 70 extends downward from the tray 22 placed on the tray guide 21 at the lowermost stage thereof. Further, as shown in FIG. 7, the stopper member 70 is a member having a generally U-shaped cross section. As a result, the hollow portion S is formed by the stopper member 70 and the back surface 15D of the storage chamber 15. Then, as shown in FIG. 6, since the opening S1 on the upper side of the hollow portion S is located directly below the air outlet 54, the cold air blown out from the air outlet 54 flows in. That is, the hollow portion S functions as an air duct that supplies a part of the cold air blown out from the outlet 54 to the lower side of the lowermost tray 22, in other words, the bottom surface 15E of the storage chamber 15. It has become. Therefore, in the cooling storage 10, the stopper member 70, which is a stopper of the tray 22, can also function as an air duct, and the inside of the storage chamber 15 can be efficiently cooled.

Further, the stopper member 70 is located at the center in the width direction in the storage chamber 15. That is, the lower opening S2 of the hollow portion S faces the center in the width direction of the rear end side of the bottom surface 15E of the storage chamber 15, and cold air can be blown to that portion. Therefore, the cold air supplied to the lower side of the lowermost tray 22 can be flowed evenly to the left and right, and the inside of the storage chamber 15 can be cooled more efficiently and evenly.

As described above, the drain hose 60 crosses immediately inside the outlet 54. As shown in FIG. 5, the drain hose 60 and the stopper member 70 are arranged at positions where they do not overlap in the vertical direction, in other words, at positions shifted in the width direction (horizontal direction). The cold air toward the outlet 54 in the housing member 51 hits the drain hose 60, but since the drain hose 60 is not located above the stopper member 70, it is inside the stopper member 70 (hollow portion S). Cold air can be reliably sent.

As shown in FIGS. 2 and 7, the cooling storage 10 also extends vertically on the inner surface of the door 14, and also serves as a door-side ridge portion that projects rearward in the closed state of the door 14. The side stopper member 80 is attached. As shown in FIG. 6, the door-side stopper member 80 extends from the bottom tray guide 21 to above the top tray guide 21, and is placed at any height when the door 14 is in the closed state. It is also located on the front side with respect to the placed tray 22. That is, the door-side stopper member 80 can prevent the tray 22 from coming into contact with the inner surface of the door 14, and the tray 22 placed in the storage chamber 15 when the main cooling storage 10 is moved. The amount of movement to the front side of the door can be reduced.

Further, in the cooling storage 10, even if the tray 22 is not sufficiently inserted into the storage chamber 15 and protrudes forward, when the door 14 is closed, the door side stopper member 80 is inserted into the tray 22. The tray 22 can be pushed into the storage chamber 15 (toward the rear) in contact with the tray 22. Thereby, a gap can be secured between the front end of the tray 22 and the door 14, that is, the air flow from the bottom surface 15E side in the storage chamber 15 to the upper side can be secured, and the cooling in the storage chamber 15 can be secured. Can be done efficiently. Furthermore, since the door-side stopper member 80 is hollow, it does not obstruct the flow of air upward thereof, and the inside of the storage chamber 15 can be cooled more efficiently. Furthermore, as shown in FIG. 7, the door-side stopper member 80 is located at the center of the door 14 in the left-right direction, in other words, at the center of the storage chamber 15 in the left-right direction. Therefore, the air flow upward on the front side of the storage chamber 15 can be made even on the left and right, and the inside of the storage chamber 15 can be cooled more efficiently and evenly.

As described above, although the cooling storage 10 has a movable structure, it is possible to suppress fluctuations in the tray 22 placed in the storage chamber 15, so that the storage on the tray 22 may fall over. It can be suppressed. Further, the cooling storage 10 is provided with a portion (a ridge portion, a door-side ridge portion) protruding toward the inside of the storage chamber 15 in order to suppress fluctuation of the tray 22, but the cold air in the storage chamber 15 is provided. The flow of the storage is sufficiently secured so that the storage can be cooled efficiently.
