Description

  The present invention relates to a storage device for articles that require storage (preservation) at a temperature within a predetermined range, such as agricultural products such as rice cereals and vegetables, or foods.

  Conventionally, a low-temperature storage for agricultural products is known as this type of storage device (see, for example, Patent Document 1).

  Hereinafter, a conventional low-temperature storage disclosed in Patent Document 1 will be described with reference to the drawings.

  FIG. 6 is a perspective view of a conventional low-temperature storage disclosed in Patent Document 1. As shown in FIG. FIG. 7 is a cross-sectional view showing the internal configuration of the cooling unit of the conventional low-temperature storage.

  As shown in FIG. 6, a storage 101 used for a conventional low-temperature storage for agricultural products is provided with a cooling unit 102 at the top, an operation unit 103 for setting operation details and the like at the upper front, and a front at the front. The door 104 is provided so that it can be opened and closed.

  As described above, the cooling unit 102 is placed on the ceiling surface of the highly heat-insulating storage 101 having the door 104 on the front surface, and is fixed with bolts or the like so as not to fall or fall. Furthermore, an exterior panel 105 is provided so as to cover the cooling unit 102.

  Further, the cooling unit 102 is connected to the cooling side of the cooling unit 102 in accordance with the opening (not shown) of the ceiling surface of the storage 101, and the circulation of the cold air emitted from the cooling side of the cooling unit 102 is appropriate. It is installed so that it may be located in the approximate center part of the storage 101.

  Furthermore, a duct (not shown) is provided in the storage chamber of the storage unit 101 to restrict the cold air blown downward from the cooling unit 102 so as to circulate in the horizontal direction, and there is no uneven temperature distribution in the storage unit. Such considerations are made.

  On the other hand, the low-temperature storage for agricultural products has a function of adjusting the temperature so as to be an optimum temperature depending on the stored item in the range of about 2 ° C. to 15 ° C. When the temperature is set, the cooling unit 102 is used. Generally, it is set to an appropriate temperature with a temperature setting device (not shown) arranged in the above, or set with a temperature setting device (not shown) arranged on the door 104 of the storage 101.

  As for the arrangement of the operation unit (operation device 103), as shown in FIG. 6, the panel 105 is provided on the same plane as the door surface so as to cover the cooling unit 102 (or a part thereof) arranged on the top surface of the storage chamber. In addition to the type in which the operation device 103 is disposed in the panel 105 portion, the operation device 103 is directly embedded in the storage door surface, and the connection wiring between the operation device 103 and the cooling unit 102 is connected to the panel insulation of the door 104. Some of them are connected on the ceiling after passing through the interior.

  In order to prevent condensation around the door 104 of the storage room, a heater for preventing condensation (not shown) is usually embedded in the portion that contacts the gasket surface of the door 104 on the storage room side. The power supply for the dew condensation prevention heater is often supplied from the cooling unit 102. Therefore, the wiring connection is connected to the cooling unit 102 at the top of the storage room, and the connection cord is used to prevent exposure of the charging unit, It is protected with a metal cover etc. from the viewpoint of preventing rattling.

  Next, the internal configuration of the cooling unit 102 of the storage 101 will be briefly described with reference to FIG.

  As shown in FIG. 7, the inside of the cooling unit 102 is formed with a cooling chamber 112 that is thermally insulated by a heat insulator 111 and a machine chamber 113 that is partitioned from the cooling chamber 112 by the heat insulator 111.

  The cooling chamber 112 is provided with a cooler 114, a cooler blower 115, and a cold air inlet 116 and a cold air outlet 117 located on the same bottom surface with the cooler 114 interposed therebetween. Further, the machine room 113 is provided with a compressor 119, a radiator 120, and a radiator fan 121.

  A drain pan 122 is disposed below the cooler 114 of the cooling unit 102, and a drain pipe 124 for draining drain water to the evaporation pan 123 of the machine chamber 113 is provided in the drain pan 122. Further, the evaporating tray 123 is provided with a refrigerant pipe 119a on the discharge side of the compressor 119 of the refrigerant circuit and evaporation paper 125 for promoting evaporation so that heat can be transferred to the drain water flowing from the water pipe 124.

  About the conventional low temperature storage for agricultural products comprised as mentioned above, the operation | movement is demonstrated below.

  The inside of the storage 101 is cooled by introducing the cold air cooled by the cooler 114 of the cooling unit 102 from the cold air outlet 117. During this cooling, moisture in the air in the storage chamber condenses on the surface of the cooler 114 and becomes drain water, which is dripped onto the drain pan 122.

  Also, as the operation time elapses, moisture condenses on the surface of the cooler 114 and gradually accumulates as frost. When the frost adhering to the cooler 114 increases, the defrosting operation is performed at an appropriate time. Also at this time, the frost adhering to the surface of the cooler 114 is melted and dropped onto the drain pan 122.

  The drain water dripped on the drain pan 122 flows into the evaporating tray 123 through the water conduit 124. The drain water flowing into the evaporating dish 123 is evaporated by the action of the exhaust heat heated by the radiator 120, the heat of the high-temperature refrigerant flowing through the refrigerant pipe 119a on the discharge side of the compressor 119, and the evaporating paper 125. .

JP 2003-35482 A

  However, in the conventional low temperature storage configuration, in order to efficiently heat the refrigerant pipe 119a on the discharge side of the compressor 119 disposed in the evaporating dish 123, the refrigerant pipe 119a on the discharge side of the compressor 119 There was a drawback that it costly to adhere to the evaporating dish 123.

  In addition to the above, there is a method in which the refrigerant pipe 119a is disposed with a gap so as not to interfere with the bottom surface of the evaporating dish 123. There was a fault that the evaporation performance of drain water was inferior.

  Further, in the promotion of evaporation by the evaporative paper 125, when the evaporative paper 125 is placed in close contact with the bottom surface of the evaporating dish 123, the drain water is always present, and mold or the like is generated in the evaporative paper 125 over a long period of use. There was the fault that evaporation performance was inferior.

  More specifically, when low-temperature drain water flowing out from the drain pan 122 accumulates in the evaporating tray 123, if the heat of the refrigerant pipe 119a cannot be used, dew condensation occurs on the back surface of the evaporating tray 123, and in the worst case, the top of the storage 101 is stored. There was a problem that condensed water accumulated on the surface.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide an article storage device that is low in cost and has good drain water evaporation performance.

  In order to achieve the above-mentioned object, the article storage device of the present invention is configured so that the evaporating dish at the place where the high-pressure pipe on the discharge side of the compressor is substantially in contact with the bottom surface is provided at the place where the evaporating paper is provided in the evaporating dish. When the water level exceeds a predetermined water level not less than the height of the arrangement space of the high-pressure pipe that is routed so as to be substantially in contact with the bottom surface of the evaporating dish, the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish. Only the drain water that flows into the location where the evaporative paper is provided from the location where the evaporating paper is provided is configured to flow.

  Thereby, it is possible to provide an article storage device that is low in cost and efficient in drain evaporation performance.

Perspective view of conventional cold storage Cross-sectional view showing the internal structure of the cooling unit of the conventional low-temperature storage

  1st invention has an evaporating dish which evaporates the drain water which flowed in from the drain pan, the high pressure pipe which is the discharge side of a compressor is drawn around so that it may be in contact with the bottom of the evaporating pan from above, Evaporating paper for evaporating the drain water in the evaporating dish is provided at a location farther from the inflow portion of the drain water than a location where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish, and the evaporating paper is provided. The arrangement of the high-pressure pipe is such that the water level of the evaporating dish where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish is routed so that the water level of the evaporating dish is substantially in contact with the bottom surface of the evaporating dish. By exceeding a predetermined water level that is equal to or higher than the height of the space, only drain water that flows into the location where the evaporative paper is provided from the location where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish is configured to flow. It is an article storage device.

  With the above configuration, the drain water flowing into the location where the evaporative paper is provided becomes drain water after being heated by heat exchange with the high-pressure pipe, and the drain water immersed in the evaporative paper is preliminarily generated by the high heat of the high-pressure pipe. It is warmed up and easily evaporated.

  The drain water immersed in the evaporative paper is easily evaporated because it is absorbed by the evaporative paper in a state where the water temperature once rises due to the high heat of the high-pressure pipe of the compressor.

  In addition, it is easy for the evaporative paper not to be wet with drain water, and it is possible to suppress the occurrence of mold on the evaporative paper.

  Therefore, drain water can be efficiently evaporated at low cost. In addition, since the temperature of the drain water in the evaporating dish rises due to heat from the high-pressure pipe of the compressor, it is possible to suppress the occurrence of condensation on the back surface of the evaporating dish.

  According to a second aspect of the invention, particularly in the first aspect of the invention, the evaporating dish has a bottom surface of the space where the evaporating paper is disposed, and a bottom surface of the space where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish. Also, it has a two-stage structure that is higher than the height of the space in which the high-pressure pipe is drawn so as to be substantially in contact with the bottom surface of the evaporating dish.

  With the above configuration, in the space where the evaporating paper is arranged, the water level of the evaporating dish in the space where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish exceeds the predetermined water level, so that the high-pressure pipe becomes the bottom surface of the evaporating dish. Only the drain water that flows into the space where the evaporation paper is disposed can be allowed to flow in from the space substantially in contact with the water.

  Also, the water level of the space where the evaporative paper is placed is linked to the water level of the space where the high-pressure tube is substantially in contact with the bottom surface of the evaporating dish, and the water level of the space where the high-pressure tube is approximately in contact with the bottom surface of the evaporating dish. However, if the water level falls below the predetermined water level, the drain water in the space where the evaporative paper is disposed disappears, the evaporative paper is not easily wet with the drain water, and the occurrence of mold or the like on the evaporative paper can be suppressed. .

  According to a third aspect of the invention, in the first aspect of the invention, in the first aspect of the invention, the partition plate having a height equal to or higher than the height of the space in which the high-pressure pipe is arranged so as to substantially contact the bottom surface of the evaporation tray. Thus, the first evaporating chamber in which the high-pressure pipe that is substantially in contact with the bottom surface of the evaporating dish is disposed and the second evaporating chamber in which the evaporating paper is disposed are partitioned.

  With the above configuration, in the second evaporation chamber in which the evaporation paper is disposed, the water level of the evaporation tray of the first evaporation chamber in which the high-pressure pipe is disposed exceeds a predetermined water level, so that the first evaporation chamber is changed to the second evaporation chamber. Only the drain water that flows in can flow in.

  Moreover, it is only necessary to provide a partition plate while keeping the bottom positions of the first evaporation chamber and the second evaporation chamber the same, and the amount of drain water retained in the evaporation dish is not increased by raising a part of the evaporation dish. Since it can be increased more than in the second invention, the storage room contains a lot of moisture such as vegetables, and even if a large amount of drain water flows into the evaporating dish, there is a margin in the amount of drain water retained The drain water can be evaporated inside the cooling unit without requiring a drain hose.

  According to a fourth aspect of the present invention, in particular, in the first to third aspects of the invention, the blower for the condenser is disposed so as to promote the vaporization of drain water from the evaporating dish and the evaporative paper. The operation of the blower is sometimes continued for a predetermined time, and evaporation can be promoted by blowing air from the condenser blower during the defrosting operation in which drain water is most likely to flow.

  Hereinafter, an embodiment of an article storage device of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a perspective view in which a part of a door body of an article storage device according to Embodiment 1 of the present invention is cut away. FIG. 2 is a cross-sectional view showing the internal structure of the cooling unit mounted on the article storage device of the embodiment. FIG. 3 is a perspective view showing the configuration of the evaporating dish in the article storage device of the embodiment.

  In the present embodiment, an agricultural product low-temperature storage (hereinafter referred to as a storage) that uses the article storage device for storing grains, vegetables, and the like will be described as an example.

  First, the configuration of the storage will be described with reference to FIG. As shown in FIG. 1, a storage 1 that is an article storage device according to the present embodiment stores an article (not shown) such as a grain made up of a heat insulating box that has a front surface that is a main body of the storage 1. It is comprised from the chamber 2 and the door body 3 which opens and closes opening of the front (front) of the storage chamber 2. As shown in FIG.

  Further, a dew-proof heater 23 for preventing dew condensation is disposed on the periphery of the opening of the storage chamber 2. Furthermore, a cooling unit 5 for cooling the inside of the storage chamber 2 is mounted on the ceiling surface of the storage chamber 2.

  Next, the cooling unit 5 will be described with reference to FIG. As shown in FIG. 2, the rectangular main body 7 of the cooling unit 5 has a cooling chamber 9 surrounded by a heat insulator 10 on the right side and a machine chamber 8 on the left side.

  In the machine room 8 in which the air inlet 8a is formed on the front surface and the air outlet 8b is formed on the rear surface, the compressor 11 disposed in the back left and the inlet 8a are adjacent to and parallel to the inlet 8a. A condenser 12 for the condenser 12 which is arranged on the back side of the condenser 12 to be blown to the condenser 12 and is also blown to the compressor 11, and a condenser 12 for the condenser 12. An evaporating dish for evaporating condensed water (drain water) disposed in the air flow path of the air blower 13 between the compressor 11 and the cooling chamber 9 behind the air blower 13 and generated in the cooling chamber 9 and led to the machine chamber 8. 14

  Further, a high-pressure pipe 11 a on the discharge side of the compressor 11 is routed from the top so as to contact the bottom surface of the evaporating dish 14 so as to exchange heat with the evaporating dish 14. Condensed water (drain water) accumulated in the water is heated by the heat of the high-pressure pipe 11a, and if the blower 13 is in operation, it evaporates while receiving vaporization acceleration from the blower 13. Further, in the evaporating dish 14, the portion that is easily subjected to the air blown from the blower 13, the heat of the compressor 11, and the air blown after cooling the compressor 11 comes into contact with the condensed water (drain water) in the evaporating dish 14, and the capillary phenomenon. Evaporating paper 14b to be sucked up is provided, and evaporating performance is enhanced by the air blowing from the blower 13, the heat of the compressor 11, and the vaporization promoting action by the blown air after cooling the compressor 11.

  Further, on the bottom surface of the cooling chamber 9 surrounded by the heat insulator 10, a suction port 18 and a blowout port 19 that open longer in the front-rear direction in the storage chamber 2 than the ceiling surface of the storage chamber 2, and a suction port 18 on the right side, The air outlet 19 is provided on the left side with a gap left and right.

  Further, in the cooling chamber 9, an evaporator 15 disposed in parallel in the front-rear direction at a position between the suction port 18 and the blowout port 19, and evaporation so that air in the storage chamber 2 flows to the evaporator 15. There are two blowers 16 for the evaporator 15 disposed horizontally on the left side of the container 15, and a drain pan 17 that receives condensed water (drain water) condensed on the evaporator 15 below the evaporator 15.

  And the compressor 11, the condenser 12, the pressure reduction means (not shown), and the evaporator 15 are connected cyclically | annularly with the refrigerant pipe, and comprise the refrigerating cycle.

  Further, a drain pipe 20 is provided that guides the condensed water (drain water) of the evaporator 15 accumulated in the drain tray 17 of the cooling chamber 9 to the evaporation tray 14 through the heat insulator 10.

  Further, at the position of the predetermined water level of the evaporating dish 14, the condensed water (drain water) exceeding the predetermined water level is stored so that the water level of the condensed water (drain water) accumulated in the evaporating dish 14 does not exceed the predetermined water level. An overflow pipe 14a leading to the outside of the cooling unit 5 is provided. This overflow pipe 14a extends from the cooling unit 5, and when a large amount of drain water comes out when storing vegetables or the like, by connecting a drain hose, the drain evaporation in the evaporating dish 14 will not be in time, and the storage chamber Consideration is given so that the condensed water (drain water) does not overflow on the ceiling surface of No.2.

  Next, the operation | movement which performs the cooling storage of the store | warehouse | chamber 1 of this Embodiment comprised as mentioned above is demonstrated.

  A refrigeration cycle is formed by operating the blower 13 for the compressor 11, the condenser 12 and the blower 16 for the evaporator 15, and the condenser 12 radiates heat while obtaining an airflow effect as indicated by an arrow X in FIG. 2. On the evaporator 15 side, a cooling (endothermic) action is performed while obtaining an air flow as indicated by an arrow Y.

  Therefore, in the storage chamber 2, cooling is performed by circulation of air that is sucked from the suction port 18 of the cooling unit 5 and passes through the evaporator 15 and is supplied from the blowout port 19 into the storage chamber 2. Thereby, storage articles such as grains stored in the storage chamber 2 can be stored.

  In addition, a control device (not shown) controls the operation of the compressor 11 and the like so that the inside of the storage chamber 2 is maintained at the temperature set by the operation unit 21 disposed on the door 3 on the front surface of the storage 1. Thus, the temperature is maintained within a predetermined temperature range.

  With this cooling operation, condensation occurs in the evaporator 15, and the condensed water (drain water) of the evaporator 15 is dripped onto the drain pan 17 disposed below the evaporator 15. When the amount of dew condensation water (drain water) accumulated in the drain pan 17 increases, the dew condensation water (drain water) in the drain pan 17 flows through the drain line 20 to the evaporation pan 14 provided in the machine chamber 8.

  On the other hand, if the above-described cooling operation is performed continuously for a long time, the condensed water in the evaporator 15 becomes frost, and this frost grows to hinder the cooling action of the evaporator 15. A so-called defrosting operation for removing the frost attached to 15 is performed.

  When such a defrosting operation is performed, a large amount of water melted from the frost in a short time is dripped into the drain pan 17 and flows to the evaporating tray 14 through the drain line 20.

  Here, the configuration of the evaporating dish 14 will be described with reference to FIG. First, the evaporating dish 14 includes a space 14c on the cooling chamber 9 side that is routed so that the high-pressure pipe 11a of the compressor 11 comes into contact with the bottom surface of the evaporating dish 14, and a compression in which the evaporating paper 14b is disposed. The space 14d is divided into a space 14d on the machine 11 side, and the position of the bottom surface of the space 14d is higher than the bottom surface of the space 14c by more than the height of the arrangement space of the high pressure pipe 11a routed so as to be in contact with the bottom surface of the evaporating dish 14. It has a step structure.

Therefore, the dew condensation water (drain water) in the space 14d becomes the dew condensation water (drain water) after being heated by heat exchange with the high pressure pipe 11a in the space 14c, and the dew condensation water (drain water) immersed in the evaporating paper 14b is In advance, the high-pressure pipe 11a is warmed by high heat and easily evaporated.

  Next, the evaporation effect | action of dew condensation water (drain water) is demonstrated. Condensed water (drain water) that has flowed into the evaporating dish 14 through the drain line 20 is temporarily stored in a space 14c in which the high-pressure pipe 11a of the compressor 11 is routed, and the condensed water (drain water) is It is evaporated by the heat of the high pressure pipe 11a. At this time, the vaporization action is also promoted by the air flow by the blower 13, and the condensed water evaporates without flowing out of the overflow pipe 14a.

  Further, when drain water accumulates in the space 14c of the evaporating dish 14 above the water level at the bottom surface position of the space 14d, it evaporates due to the action of the evaporating paper 14b disposed in the space 14d of the evaporating dish 14. The condensed water (drain water) immersed in the evaporative paper 14b is easily evaporated because it is absorbed by the evaporative paper 14b once the water temperature has risen due to the high heat of the high-pressure pipe 11a of the compressor 11.

  The article storage apparatus according to the present embodiment includes an evaporating dish 14 that evaporates drain water flowing from the drain dish 17 of the evaporator 15, and the high-pressure pipe 11 a of the compressor 11 evaporates from above in a space 14 c of the evaporating dish 14. The drain water in the evaporating dish 14 is evaporated in a space 14d that is drawn so as to be substantially in contact with the bottom surface of the dish 14 and that is farther from the inflow portion of the drain water than the space 14c in which the high-pressure pipe 11a is substantially in contact with the bottom surface. In the space 14d where the evaporative paper 14b is provided, and in the space 14d where the evaporative paper 14b is provided, the water level of the space 14c in which the high pressure pipe 11a is substantially in contact with the bottom surface is in contact with the bottom surface of the evaporating dish 14 in the space 14c. Since the drain water that flows into the space 14d from the space 14c only flows into the space 14d by exceeding a predetermined water level that is equal to or higher than the height of the arrangement space 11a. Drain water immersion in 4b, once because the water temperature is absorbed by the vaporization sheet 14b while elevated, easily evaporated.

  Further, in the case where grains or the like that hardly generate condensed water (drain water) are stored, only the action of the high-pressure pipe 11a in the space 14c of the evaporating dish 14 is sufficient, and the evaporating paper 14b. Does not get wet with drain water, and can suppress the occurrence of mold and the like after long-term use.

  The water level of the space 14d where the evaporative paper 14b is disposed is linked to the water level of the space 14c where the high pressure pipe 11a of the compressor 11 is substantially in contact with the bottom surface of the evaporating dish 14, and the high pressure pipe 11a is If the water level of the space 14c that is substantially in contact with the bottom surface of the water drops below a predetermined water level, the drain water in the space 14d in which the evaporative paper 14b is disposed disappears, and the evaporative paper 14b is not easily wet with the drain water. Further, it is possible to suppress the occurrence of mold and the like on the evaporation paper 14b.

  Moreover, since the temperature of the dew condensation water (drain water) in the space 14c of the evaporating dish 14 is increased by the heat from the high pressure pipe 11a of the compressor 11, there is no concern that dew condensation occurs on the back surface of the evaporating dish 14 or the like.

(Embodiment 2)
FIG. 4 is a perspective view showing the configuration of the evaporating dish of the article storage device in Embodiment 2 of the present invention. In the present embodiment, only the configuration of the evaporating dish 14 is different from that of the first embodiment. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. .

As shown in FIG. 4, in the present embodiment, a location where the high-pressure pipe 11 a of the compressor 11 is routed so as to contact the bottom surface of the evaporating dish 14 and a location where the evaporating paper 14 b is disposed. A partition plate 14e having a height equal to or higher than a predetermined height (the height of the arrangement space of the high-pressure pipe 11a routed so as to be in contact with the bottom surface of the evaporating dish 14) is provided on the bottom surface of the evaporating dish 14 between The partition plate 14e partitions the evaporating dish 14 into a first evaporating chamber 14g in which the high-pressure pipe 11a of the compressor 11 is arranged and a second evaporating chamber 14h in which the evaporating paper 14b is arranged.

  In the above configuration, until the dew condensation water (drain water) in the first evaporation chamber 14g exceeds the height of the partition plate 14e, the dew condensation water (drain water) flows from the first evaporation chamber 14g into the second evaporation chamber 14h. Rather, the dew condensation water (drain water) in the first evaporation chamber 14g exceeding the height of the partition plate 14e flows into the second evaporation chamber 14h.

  In the present embodiment, the positions of the bottom surfaces of the first evaporation chamber 14g and the second evaporation chamber 14h remain the same, and the arrangement of the high-pressure pipe 11a that is routed so as to be in contact with the bottom surface of the evaporation dish 14 is arranged. It is only necessary to provide a partition plate 14e having a height equal to or higher than the height of the space, and the amount of condensed water (drain water) retained in the evaporating dish 14 by the amount that does not raise a part of the evaporating dish 14 to the bottom. It can be increased from 1.

  As a result, even when a large amount of moisture such as vegetables is stored in the storage chamber 2, even when a large amount of condensed water (drain water) flows into the evaporating dish 14, the amount of condensed water (drain water) retained is reduced. Since there is a margin, no drain hose is required, and the condensed water (drain water) can be evaporated inside the cooling unit 5.

(Embodiment 3)
FIG. 5 is a perspective view showing the configuration of the evaporating dish of the article storage device according to Embodiment 3 of the present invention. In the present embodiment, only the configuration of the evaporating dish 14 is different from that of the first or second embodiment, and the same reference numerals are given to the same configurations in the present embodiment as in the first or second embodiment. Detailed description thereof will be omitted.

  As shown in FIG. 5, in the present embodiment, the third evaporating chamber 14 f connected to the emergency overflow pipe 14 a is arranged in the evaporating dish 14, and the overflow pipe 14 a is arranged near the bottom surface of the unit base of the cooling unit 5. Yes.

  With the above configuration, even when the material of the evaporating dish 14 is resin or the like, the outer surface of the cooling unit 5 is covered with metal, and entry into the cabinet due to rattling can be prevented.

(Embodiment 4)
The article storage device according to the fourth embodiment of the present invention is configured to continue the operation of the blower 13 for the condenser 12 for a predetermined time during defrosting in addition to any of the configurations of the first to third embodiments. With the above configuration, during the defrosting operation in which the dew condensation water (drain water) is most likely to flow, the drain water accumulated in the evaporating dish 14 is naturally evaporated and then blown by the blower 13 for the condenser 12. It can actively promote evaporation.

  The article storage apparatus according to the present invention can improve drain evaporation performance at low cost, and is not limited to storage of agricultural products such as grains, but is widely used as an article storage apparatus that requires dehumidification, drying, and constant temperature management. It can be used.
