Abstract

PROBLEM TO BE SOLVED: To provide an article storage device of low costs and high drain durability.SOLUTION: Evaporation paper 14b is disposed in a state of closely kept into contact with a bottom surface of an evaporation pan 14 in the vicinity (space 14c) of a drain pipe conduit 20 in the evaporation pan 14, and a high-pressure pipe 11a as a discharge side of a compressor is arranged while approximately kept into contact with the bottom surface of the evaporation pan 14 in a space 14d of the evaporation pan 14 separating from the drain pipe conduit 20 with respect to the space 14c. As the evaporation pan 14 has a two-stage structure in which a bottom surface of the space 14d is higher than a bottom surface of the space 14c by a predetermined height or more, and is constituted to allow only the drainage not completely evaporated in the space 14c provided with the evaporation paper 14b, to flow to the space 14d in which the high-pressure pipe 11a is arranged, an amount of the drainage flowing into the space 14d provided with the high-pressure pipe 11a can be reduced when storing grain or the like which is less likely to generate the drainage, and excessive anti-corrosion treatment to the high-pressure pipe 11a becomes unnecessary.

Description

  The present invention relates to a storage device for articles that require storage (preservation) at a predetermined range of temperature, such as rice cereals, agricultural products such as 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. 7 is a perspective view of a conventional low-temperature storage disclosed in Patent Document 1. FIG. FIG. 8 is a cross-sectional view showing the internal configuration of the cooling unit of the conventional low-temperature storage.

  As shown in FIG. 7, a storage 101 used for a conventional low-temperature storage for agricultural products has a cooling unit 102 disposed at the top, an operation unit 103 for setting operation details and the like provided 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. 7, 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. 8, the inside of the cooling unit 102 is formed with a cooling chamber 112 having a heat insulating structure by a heat insulator 111 and a machine chamber 113 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, the discharge of the compressor 119 is used in order to efficiently use the heat of the refrigerant pipe 119a on the discharge side of the compressor 119 disposed in the evaporating dish 123 for drain water evaporation. There is a disadvantage that it takes cost to closely contact the refrigerant pipe 119a on the side and 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.

  More specifically, in order to prevent corrosion when the refrigerant pipe 119a is immersed in drain water, the outer surface of the refrigerant pipe 119a is usually covered with a waterproof tube or coated with corrosion resistance. When the frequency is high, the deterioration of the corrosion prevention progresses, and in the worst case, there is a problem that the refrigerant pipe 119a is corroded to cause a gas leak and cannot be cooled.

  The present invention solves the above-described conventional problems, and an object thereof is to provide an article storage device that has low cost and good drain durability.

  In order to achieve the above object, the article storage device of the present invention is provided near the inflow portion of the drain water in the evaporating dish so that the evaporating paper for evaporating the drain water in the evaporating dish is in contact with the bottom surface of the evaporating dish, The high pressure pipe on the discharge side of the compressor is routed from above at a location farther from the drain water inflow portion than the location where the evaporative paper is provided, so that the high pressure tube is substantially in contact with the bottom surface of the evaporating dish from above. From the upper part, the high pressure pipe is connected to the bottom surface of the evaporating dish from the position where the evaporating paper is provided by the water level of the evaporating dish at a location where the evaporating paper is provided exceeding a predetermined water level. However, it is configured such that only drain water that flows into a portion substantially in contact with the bottom surface of the evaporating dish flows.

  With this configuration, it is possible to provide an article storage device that has low cost and good drain durability.

  The article storage device of the present invention can provide a low-temperature storage with low drainage cost and good drain durability at the time of evaporation of drain water.

  1st invention has an evaporating dish which evaporates drain water which flowed in from a drain pan of an evaporator, and evaporating paper which evaporates drain water in the evaporating dish near the inflow part of the drain water in the evaporating dish A high-pressure pipe which is provided on the bottom surface of the evaporating dish and is at the discharge side of the compressor at a position farther from the drain water inflow portion than a position where the evaporating paper is provided is a bottom surface of the evaporating dish from above. The water level of the evaporating dish at the position where the evaporating paper is provided exceeds a predetermined water level at a position where the evaporating paper is substantially in contact with the bottom surface of the evaporating dish from above. Thus, only the drain water that flows into the location where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish from the location where the evaporative paper is provided.

  With the above configuration, the drain water flowing into the location where the high-pressure pipe substantially contacts the bottom surface of the evaporating dish from above is provided with the evaporating paper when the level of the evaporating dish at the location where the evaporating paper is provided exceeds a predetermined water level. It becomes drain water which flows into the location where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish.

  In other words, only the drain water that could not be evaporated by the evaporative paper will flow from above into the location where the high-pressure pipe is substantially in contact with the bottom of the evaporating dish. It is possible to suppress the amount of drain water flowing into the place where the is provided.

  In order to prevent corrosion due to drain water, high pressure pipes are usually covered with a waterproof tube on the outer surface of the pipe or coated with corrosion resistance, but most of the drain water evaporates with evaporative paper. Therefore, the frequency of immersion of drain water can be suppressed, and it is not necessary to prevent excessive corrosion.

  Therefore, the durability can be improved at low cost without any gas leak due to corrosion of the refrigerant pipe.

  In a second aspect of the invention, particularly in the first aspect of the invention, the bottom surface of the space in which the high-pressure pipe is substantially in contact with the bottom surface of the evaporation tray is arranged from the bottom surface of the space in which the evaporation paper is disposed. Is a high two-stage structure.

  With the above configuration, in the space where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish, the water level of the evaporating dish in the space where the evaporating paper is disposed is the predetermined water level (the high-pressure pipe is substantially the same as the bottom surface of the evaporating dish. The high-pressure tube evaporates from the space where the evaporating paper is placed by exceeding the height of the bottom surface of the space in contact and the height difference between the height of the bottom surface of the space where the evaporating paper is located) Only drain water flowing into a space substantially in contact with the bottom surface of the water can flow in.

  In addition, the water level of the space where the high-pressure tube is substantially in contact with the bottom surface of the evaporating dish is linked to the water level of the space where the evaporative paper is disposed, and the water level of the space where the evaporative paper is disposed falls below the predetermined water level. For example, there is no drain water in the space where the high-pressure pipe is substantially in contact with the bottom surface of the evaporating dish, and the state where the surface of the high-pressure pipe is not wet with the drain water is likely to occur, and the immersion frequency of the drain water can be suppressed.

  According to a third aspect of the present invention, in the first aspect of the present invention, in the first aspect of the invention, the evaporating dish is a partition plate provided from the bottom surface of the evaporating dish to a height equal to or higher than a predetermined height. It is partitioned into a chamber and a second evaporation chamber in which the high-pressure pipe that is substantially in contact with the bottom surface of the evaporation dish is disposed.

  With the above configuration, in the second evaporation chamber in which the high-pressure pipe is disposed, the water level of the evaporation tray of the first evaporation chamber in which the evaporation paper is disposed exceeds the 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 invention, in addition to the first to third aspects of the invention, a heat insulator that surrounds and insulates the evaporator is provided so as to cover at least a part of the upper surface of the evaporative paper from above and in the upward direction of the evaporative paper. The evaporative paper can be fixed at a low cost, and the evaporative paper can be prevented from falling over or being removed from the evaporating dish during transportation.

  According to a fifth aspect of the present invention, in particular, in the first to fourth aspects of the invention, the blower for the condenser is arranged so that the blowing air from the evaporating dish and the evaporating paper is promoted to vaporize the defroster of the evaporator. 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 air conditioning 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 article storage device will be described as an example of an agricultural product low-temperature storage (hereinafter referred to as storage) for storing rice grains, vegetables and the like.

  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, the evaporating dish 14 comes into contact with the condensed water (drain water) in the evaporating dish 14 at locations where it 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. The evaporating paper 14b sucked up by the phenomenon is provided, and the drain water can be evaporated by the air blowing promotion action by the air blown from the blower 13, the heat of the compressor 11 and the air blown after cooling the compressor 11.

  Further, the high-pressure pipe 11a on the discharge side of the compressor 11 is drawn from above so as to be substantially in contact with the bottom surface of the evaporating dish 14 so that heat exchange with the evaporating dish 14 is performed. (Drain water) is heated by the heat of the high-pressure pipe 11a, and if the blower 13 is operated, the vaporization is accelerated by the blowing from the blower 13 and the evaporation performance is enhanced.

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 has a space 14c on the side of the overflow pipe 14a where the evaporating paper 14b is disposed, and a space closer to the center where the high-pressure pipe 11a of the compressor 11 is routed so as to substantially contact the evaporating dish 14. 14d, and has a two-stage structure in which the bottom surface of the space 14d is higher than the bottom surface of the space 14c.

  In the space 14c, the evaporating paper 14b is disposed in the vicinity of the drain water outlet and in close contact with the bottom surface of the evaporating dish 14, so that the drain water can be efficiently absorbed into the evaporating paper 14b. Further, the positional relationship between the space 14c and the space 14d is such that the space 14d is higher than a predetermined height, and a large amount of drain water is drained so that the drain water is immersed in the space 14d. The drain water is warmed by the high heat, and evaporation can be promoted.

  Next, the evaporation effect | action of dew condensation water (drain water) is demonstrated.

  The drain water flowing into the evaporating dish 14 through the drain pipe 20 is temporarily stored in the space 14c where the evaporating paper 14b is disposed, and overflows due to the water absorbing action of the evaporating paper 14b and the vaporization promoting action of the blower 13. It evaporates without flowing out of the water pipe 14a.

  In particular, when items such as grains that are relatively difficult to generate drain water are stored, the vaporizing action of the evaporating paper 14b in the space 14c of the evaporating dish 14 and the air flow of the blower 13 is sufficient. No low-temperature drain water stays on the bottom surface of 14, and there is no fear of condensation on the back surface of the evaporating dish 14.

  By this evaporation action, the level of the drain water in the space 14c in which the evaporation paper 14b is arranged up to the level of the bottom surface of the space 14d in which the high pressure pipe 11a is arranged does not rise, and the high pressure pipe 11a becomes the drain water. Without soaking, there is no need to worry about corrosion of the high-pressure pipe 11a due to drain water.

  Accordingly, since most of the drain water can be evaporated by the evaporating paper 14b, the immersion frequency of the drain water can be suppressed, and the outer surface of the high pressure pipe 11a can be prevented to prevent corrosion of the high pressure pipe 11a by the drain water. There is no need to prevent excessive corrosion such as covering the pipe with a waterproof tube or applying a corrosion-resistant coating to the high-pressure pipe 11a. Can do.

  Moreover, when the thing which produces | generates drain water comparatively easily, such as vegetables, is accommodated, drain water will accumulate more than the water level of the space 14c of the evaporating dish 14. FIG. At this time, the drain water is promoted to evaporate by the high heat of the high-pressure pipe 11a of the compressor 11 disposed in the space 14d of the evaporating dish 14. At this time, the vaporization action is also promoted by the air flow by the blower 13, and the condensed water is evaporated without flowing out of the overflow pipe 14a.

As described above, the storage 1 (article storage device) of the present embodiment includes the evaporating dish 14 that evaporates the drain water flowing from the drain dish 17 of the evaporator 15 through the drain pipe line 20. The evaporating paper 14b for evaporating the drain water in the evaporating dish 14 is provided in the vicinity (space 14c) of the water inflow portion (outlet of the drain pipe 20) so as to contact the bottom surface of the evaporating dish 14, and the evaporating paper 14b is provided. The high-pressure pipe 11a on the discharge side of the compressor 11 is located above the evaporating dish 14 at a location (space 14d) farther from the inflow portion of the drain water (outflow port of the drain pipeline 20) than the provided location (space 14c). A place where the evaporative paper 14b is provided (space 14c) at a place (space 14d) where the high-pressure pipe 11a is drawn so as to be substantially in contact with the bottom surface and substantially contacts the bottom surface of the evaporating dish 14 from above. When the water level of the evaporating dish 14 exceeds a predetermined water level, the high-pressure pipe 11a flows from the position where the evaporating paper 14b is provided (space 14c) to the position where the bottom surface of the evaporating dish 14 is substantially in contact (space 14d). The bottom surface of the space 14d in which the high-pressure pipe 11a is substantially in contact with the bottom surface of the evaporating dish 14 is higher than the bottom surface of the space 14c in which the evaporating paper 14b is disposed so that only the drain water flows. It has a step structure.

  With the above configuration, the drain water flowing into the location (space 14d) where the high-pressure pipe 11a substantially contacts the bottom surface of the evaporating dish 14 from above is the level of the evaporating dish 14 at the location where the evaporating paper 14b is provided (space 14c). By exceeding the predetermined water level, drain water flows from the location where the evaporating paper 14b is provided into the location where the high-pressure pipe 11a is substantially in contact with the bottom surface of the evaporating dish 14.

  That is, only the drain water that could not be evaporated by the evaporating paper 14b flows from above into the location (space 14d) where the high-pressure tube 11a substantially contacts the bottom surface of the evaporating dish 14, and storage such that rice grains and other drain water is difficult to generate. In this case, the amount of drain water flowing into the location (space 14d) where the high pressure pipe 11a is provided can be suppressed.

  In order to prevent corrosion due to drain water, the high pressure pipe 11a is usually covered with a waterproof tube on the outer surface of the pipe or coated with corrosion resistance, but most of the drain water is covered with the evaporation paper 14b. Since it can evaporate, the immersion frequency of drain water can be suppressed, and it is not necessary to prevent excessive corrosion.

  Therefore, the durability can be improved at low cost without any gas leak due to corrosion of the refrigerant pipe.

  Further, the water level of the space 14d where the high-pressure pipe 11a is substantially in contact with the bottom surface of the evaporating dish 14 is linked to the water level of the space 14c where the evaporating paper 14b is arranged, and the water level of the space 14c where the evaporating paper 14b is arranged. If the water level falls below a predetermined water level, there is no drain water in the space 14d in which the high pressure pipe 11a is substantially in contact with the bottom surface of the evaporating dish 14, and the surface of the high pressure pipe 11a is not easily wet with drain water. The immersion frequency of water can be suppressed.

(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, the portion where the evaporating paper 14 b is disposed and the high-pressure pipe 11 a of the compressor 11 are routed so as to be substantially in contact with the bottom surface of the evaporating dish 14 from above. A partition plate 14e is provided over a predetermined height from the bottom surface of the evaporation tray 14 between the first evaporation chamber 14g in which the evaporation paper 14b is disposed, and the partition plate 14e. The high pressure pipe 11a of the compressor 11 is partitioned into a second evaporation chamber 14h.

  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, it is only necessary to provide a partition plate 14e having a height equal to or higher than a predetermined height while keeping the bottom surface positions of the first evaporation chamber 14g and the second evaporation chamber 14h the same. The amount of condensed water (drain water) retained in the evaporating dish 14 can be increased as compared with the first embodiment by the amount that is not raised.
