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 an internal configuration of a cooling unit of a conventional low-temperature storage.

  As shown in FIG. 6, a storage 101 used for a conventional low-temperature storage for agricultural products has 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 surface. The door 104 is provided to be openable and closable.

  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 shown in FIG. 6, the operation unit (operation device 103) is arranged on the same plane as the door so as to cover the cooling unit 102 (or a part thereof) arranged on the top surface of the storage room. In addition to the type in which the operation unit 103 is arranged in the panel 105 portion, the operation unit 103 is directly embedded in the door 104 and the connection wiring between the operation unit 103 and the cooling unit 102 is connected to the panel 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 (not shown) for preventing condensation is usually embedded in a 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. Protected with a metal cover or the like 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 tray 122 is disposed below the cooler 114 of the cooling unit 102, and a drain pipe 124 that drains drain water to the evaporation tray 123 of the machine chamber 113 is provided in the drain tray 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.

  Further, 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. .

In addition to the above, there is a method of arranging the refrigerant pipe 119a with a gap so as not to interfere with the bottom surface of the evaporating dish 123. However, if the water level does not rise to the height where the refrigerant pipe 119a is located, the heat of the refrigerant pipe 119a is used. There was a problem that the evaporation performance of drain water was inferior.

  More specifically, when dust such as dust accumulates on the evaporation paper 125 after a long period of use, there is a problem that the evaporation performance is inferior.

  An object of the present invention is to solve the above-described conventional problems, and to provide an article storage device that is low in cost and has good drain water evaporation performance.

(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 of the article storage device according to Embodiment 1 of the present invention. FIG. 3 is a perspective view showing the configuration of the evaporating dish of the article storage device according to Embodiment 1 of the present invention.

  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. A chamber 2 and a door body 3 that opens and closes an opening on the front surface (front surface) of the storage chamber 2 are configured.

  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. There is a condenser 12 arranged in Further, two fans 13 are arranged horizontally on the back surface of the condenser 12 for blowing air to the condenser 12 and blown also to the compressor 11, and the compressor is behind the blower 13 for the condenser 12. 11 and an evaporating tray 14 for evaporating condensed water (drain water) generated in the cooling chamber 9 and led to the machine chamber 8.

Furthermore, at the bottom surface of the cooling chamber 9 surrounded by the heat insulator 10, there are a suction port 18 and a blowout port 19 that open longer in the front-rear direction into 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 space 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 13 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 under 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, a high-pressure pipe 11 a on the discharge side of the compressor 11 is drawn from the top to the vicinity of the bottom surface of the evaporating dish 14 so that heat exchange with the evaporating dish 14 is performed in the evaporating dish 14. Condensed water (drain water) is heated by the heat of the high-pressure pipe 11a and evaporates while being accelerated by vaporization from the blower 13 if the blower 13 is operated.

  Further, in the evaporating dish 14, at locations where the air from the blower 13, the heat of the compressor 11, and the air after cooling the compressor 11 are easily received, the capillaries come into contact with the condensed water (drain water) in the evaporating dish 14. The evaporating paper 14b sucked up by the phenomenon 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, 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 is generated in storage of vegetables, etc., by connecting a drain hose, drain evaporation in the evaporating dish 14 will not be in time. Consideration is given so that the condensed water (drain water) does not overflow on the ceiling surface of the storage chamber 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 compressor 11, the blower 13 for the condenser 12, and the blower 13 for the evaporator 15, and the condenser 12 obtains an airflow effect as indicated by an arrow X in FIG. 2. A heat dissipating action is performed, and 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 interior 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. By doing so, it is maintained within a predetermined temperature range.

  With such a cooling operation, dew condensation occurs in the evaporator 15, and the dew condensation 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 pipe 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 frost adhering to 15 is performed.

  When the defrosting operation is performed in this way, a large amount of water melted from the frost in a short time is dripped onto 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, in the evaporating dish 14, the high-pressure pipe 11 a of the compressor 11 is routed from above to the vicinity of the bottom surface of the evaporating dish 14. Further, the evaporative paper 14b has a through hole 14c having a long hole shape at a position where the lower end of the evaporative paper 14b is in close contact with the bottom surface of the evaporating dish 14 and the high-pressure pipe 11a can be substantially intimately penetrated. By inserting the high-pressure pipe 11a into the through hole 14c, the high-pressure pipe 11a and the evaporation paper 14b are integrated. Here, let through-hole 14c be a cut surface.

  Therefore, the condensed water (drain water) that has flowed into the evaporating dish 14 is immersed in the evaporating paper 14b and heated by heat exchange with the high-pressure pipe 11a, and then vaporized by the blower 13 and easily evaporated. It has become.

  Furthermore, the evaporative paper 14b has a wave shape 14e at its end surface, and is made of a highly water-absorbing paper having a plurality of gaps with a predetermined interval.

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

  Condensed water (drain water) flowing into the evaporating dish 14 through the drain line 20 is temporarily stored in the evaporating dish 14, immersed in the evaporating paper 14b, and heated by heat exchange with the high-pressure pipe 11a. Evaporated.

  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.

  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 a high-pressure pipe 11 a that is a discharge side of the compressor 11 is disposed on the evaporating dish 14 from above. A part of the evaporative paper 14b is cut so that the high-pressure pipe 11a on the discharge side of the compressor 11 can be inserted into the evaporative paper 14b provided in the evaporating dish 14 so as to be in close contact with the bottom surface. The evaporative paper 14b is disposed so that the lower end of the evaporative paper 14b is in close contact with the evaporating dish 14.

  Thereby, the heat of the high-pressure pipe 11a is efficiently transferred to the evaporating paper 14b, and the drain water is easily evaporated.

  In addition, when a comparatively difficult condensate water (drain water) such as grain is stored, the evaporative paper 14b is in a dry state due to the heat transfer action of the high pressure pipe 11a, so that it gets wet with the drain water. No, it can suppress the occurrence of mold and the like after long-term use.

Further, the wave shape 14e on the end surface of the evaporative paper 14b can suppress clogging of the gap of the evaporative paper 14b due to accumulation of rice bran, dust, etc., and the drain is stable for a long period of time without obstructing the air flow of the blower 13. Water can be evaporated.

  That is, in the present embodiment, the article storage apparatus includes an evaporating dish 14 that stores drain water flowing from the drain dish 17 of the evaporator 15 and an evaporating paper 14b that is provided in the evaporating dish 14 and evaporates the drain water. is there. Further, the high-pressure pipe 11 a that is 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, and a part of the evaporative paper 14 b is a high-pressure pipe on the discharge side of the compressor 11. A through hole 14c that is a cut surface is provided so that 11a can be closely inserted, and the lower end of the evaporating paper 14b is arranged so as to be in close contact with the evaporating dish 14. Further, the evaporative paper 14b has an end surface processed into a wave shape 14e.

  In the present embodiment, the wave shape 14e is provided on both sides of the side in the vertical direction.

  However, if a plurality of dust adhesion reducing portions are formed only at least on the end surface of the side on the air inflow side, the effect can be exhibited.

  Thereby, the processing man-hour of evaporation paper can be reduced and the significant increase in cost can be suppressed.

  In addition, this dust adhesion reducing part is formed by alternately combining upward end faces and downward end faces, and is formed in a sawtooth shape as a whole.
