The present invention has been completed based on the above circumstances, and in a heat-insulated storage that performs cold insulation using a flat plate-shaped cold storage agent, it is preferable to remove moisture on the cold storage agent, and to remove the moisture. It aims at draining properly.

  The heat insulating storage of the present invention comprises a storage room for storing stored items, and a cold storage agent room provided above the storage room and storing a flat plate-shaped cold storage agent for keeping the storage room cold. It is a storage, and in the cool storage agent chamber, a mounting shelf capable of mounting the cool storage agent in a flat state is provided, and the mounting shelf is arranged obliquely with respect to the horizontal direction. It has the characteristics.

  In the above configuration, by placing the flat plate-shaped regenerator in a flat state, the mounting space does not need to be high, and space saving is achieved. However, when the cold storage agent is placed in a flat state, moisture condensed on the surface of the cold storage agent accumulates, and in some cases, the cold storage agent is difficult to freeze or the cold storage agent is difficult to thaw. However, by placing the mounting shelf diagonally with respect to the horizontal direction as in the above configuration, moisture is drained along the slope, so that the moisture does not stay on the regenerator and the regenerator freezes. It is possible to prevent or suppress the occurrence of a problem that it is difficult to remove or that the cold storage agent is difficult to thaw.

Further, as means for solving the above-mentioned problems, the following configuration may be adopted.

  The dew tray 47 is made of a metal plate such as a stainless steel plate and has a shallow basin shape as shown in FIGS. The dew receiving tray 47 is formed in a shape in which a portion of the blower fan 45 is cut out. The dew receiving tray 47 is attached so as to have the same gradient as the flange portion 51 of the shelf support portion 50. Therefore, space saving of the cool storage agent chamber 40 can be achieved.

  The storage chamber 17 is provided below the cool storage agent chamber 40, and a shelf column is attached to the interior of the storage chamber 17. It is installed. The storage room shelf network is supported by the shelf holders at regular intervals in the vertical direction inside the shelf pillars, and a storage space for storing stored items is formed above each storage room shelf network. . In addition, a rear duct 19 is stretched on the rear surface (rear) of the storage chamber 17, and the cold air sent from the blower fan 45 passes through a space provided between the rear duct 19 and the inner wall of the storage body 11. This cold air is discharged into the storage chamber 17 from a cold air outlet provided in the rear duct 19, and the inside of the storage chamber 17 is cooled. And the circulation between the cool storage agent chamber 40 and the storage chamber 17 is performed by returning the air in the storage chamber 17 to the cool storage agent chamber 40 from the storage chamber suction port 43 provided in front. A dew condensation prevention heater is embedded in the periphery of the opening of the storage chamber 17.

  The regenerator 90 cooled (frozen) in the regenerator chamber 40 is a known one in which a hardener made of synthetic resin such as polyethylene is filled with a gelling agent, and is a flat rectangular plate as a whole. It has a shape. As shown in FIG. 10, the cold storage agent 90 has two types of sizes, and the two sides of the cold storage agent have the same length of the short sides of the plane rectangle, but the lengths of the long sides are different. Yes. Hereinafter, when distinguishing two types of cool storage agents, the cool storage agent with a shorter long side is referred to as a cool storage agent 90A, and the cool storage agent with a longer long side is referred to as a cool storage agent 90B. The cool storage agent 90A is placed on the shelf network 60 and can be accommodated in two rows in the cool storage agent chamber 40 with a space left and right. The length of the long side of the regenerator 90A is substantially equal to the distance from the central bar 67 to the vertical bar 63 at one end. Moreover, the length of the long side of the cool storage agent 90B is substantially equal to the interval between the vertical bars 63 at both ends.

  In such a configuration, the basic cooling operation of the cooling storage 10 is performed by driving a cooling device such as the compressor 21 and the cooling fan 35, and heat exchange is performed while air passes through the cooler 33. Cold air is generated, and this cold air is blown out from the cooling fan 35 to the cool storage agent chamber 40 to generate a circulating flow, thereby cooling (freezing) the cool storage agent 90, and the cool air in the cool storage agent chamber 40 is cooled by the blower fan 45. It is led to a cool air passage formed by 19 and discharged into the storage chamber 17 from a cool air outlet provided in the rear duct 19. Air that has cooled the object to be cooled stored in the storage chamber 17 is sucked into the cool storage agent chamber 40 from the storage chamber suction port 43 by a circulating flow, and the cooling fan 35 on the upper surface thereof, and thus the cooler. It is sent to 33 and cooled again. During such operation, the central portion of the shelf network 60 arranged in the cool storage agent chamber 40 is V-shaped, so that the space between the cooling fan 35 and the cool storage agent 90 is widened. So air circulation is better.

  In this embodiment, in order to freeze the cool storage agent 90, the inside of the cool storage agent chamber 40 may be cooled to about −20 ° C. Thus, in order to lower the temperature in the regenerator chamber 40 to an extremely low temperature range of about −20 ° C., the cooler 33 needs to be maintained in a correspondingly low temperature state, and it can be said that frost formation is likely to occur. Therefore, a defrosting operation is appropriately performed, and a defrosting heater 39 (see FIG. 2) including a sheathed heater is mounted on the lower surface of the cooler 33. The defrost water defrosted by the defrost heater 39 flows on the cooling duct 31 and is sent from the defrost water drain 32 at the rear to the drain evaporator disposed on the bottom surface of the storage body 11 to be evaporated.

  On the other hand, the cooling storage 10 of this embodiment can stop the operation of the cooling device and cool the inside of the storage chamber 17 with the cold storage agent 90. In such a case, the cooling devices such as the compressor 21 and the cooling fan 35 are stopped, while the blower fan 45 for adjusting the air volume between the cool storage agent chamber 40 and the storage chamber 17 is continuously driven. The cool air in the regenerator chamber 40 sent to the storage chamber 17 by the blower fan 45 is guided to the cool air passage formed by the rear duct 19 and is transferred to the storage chamber 17 from the cold air outlet provided in the rear duct 19. Discharged. Air that has cooled the object to be cooled stored in the storage chamber 17 is sucked into the cool storage agent chamber 40 from the storage chamber suction port 43 by the circulating flow, and is cooled by the cool storage agent 90. By such cold air circulation, the inside of the storage chamber 17 can be maintained at a predetermined temperature.

  Thus, when the cooling operation of the storage chamber 17 by the cool storage agent 90 is performed, dew condensation occurs on the surface of the cool storage agent 90 and moisture is generated. Since the shelf network 60 has a V shape, the moisture is collected in the rear while the shelf support portion 50 is inclined rearward while gathering in the vicinity of the center. Further, the moisture falls on the dew receiving tray 47 and flows down toward the back side along the inclination of the dew receiving tray 47. And since the condensed water drain 49 is provided in the back side, it passes through this condensed water drain 49, is sent to the drain evaporation apparatus arrange | positioned at the bottom face of the storage main body 11, and is evaporated. As described above, since the shelf support portion 50 and the dew receiving tray 47 are inclined rearward, drainage to the condensed water drain 49 provided at the rear is facilitated.

  As described above, according to the present embodiment, by placing the flat plate-shaped cold storage agent 90 in a flat state, the mounting space does not need to be high, and space saving is achieved. Further, by arranging the shelf network 60 obliquely with respect to the horizontal direction, moisture is drained along the slope, so that the moisture does not stay on the regenerator 90 and the regenerator 90 itself is difficult to freeze, or It is possible to prevent or suppress the occurrence of a problem that the regenerator 90 itself is difficult to thaw.

  Further, the shelf network 60 can be placed with the cool storage agents 90A divided into two rows, and the middle portion (center) located between the rows of the cool storage agents 90A is the lowest and becomes higher toward both ends. It has a shape. Therefore, the condensed moisture of the cool storage agent 90A collects in one place in the intermediate portion, and thus the condensed moisture can be easily discharged.

  The shelf network 60 has a center bar 67 that is arranged at the same height as both ends of the shelf network 60 in the middle portion (center portion). Thus, the shelf net 60 is provided with the central rod 67 so that the regenerators 90A placed in two rows do not collide with each other in the middle portion. By aligning the height of the central bar 67 with the heights of both ends of the shelf network 60, in the case of the cold storage agent 90B having a length longer than the distance from the intermediate part to both ends, the central bar 67 supports the cold storage agent 90B. By doing so, the large cool storage agent 90 </ b> B can be supported and placed on both ends of the placement shelf and the central bar 67. That is, both the large cool storage agent 90B and the small cool storage agent 90A can be placed on the same shelf network 60.

  The shelf network 60 is inclined so as to become lower toward the rear of the cool storage agent chamber 40. By doing in this way, the moisture which dew condensation flows toward the back of the cool storage agent chamber 40, and since the dew condensation drain 49 is provided in the back side, it is easy to guide the dew condensation water to a drainage place. Become.

  The cool storage chamber 40 is provided with a dew receiving tray 47 that receives moisture generated by condensation, and the dew receiving tray 47 is inclined in accordance with the inclination of the shelf network 60 in the front-rear direction. Therefore, since the dew receiving tray 47 is provided along the inclination of the shelf network 60, the space is saved.

  Cooling devices such as the compressor 21 and the cooling fan 35 that freeze the regenerator 90 are provided. In such a configuration, if dew condensation remains on the regenerator 90, moisture due to the dew condensation may be frozen when cooled. However, in the present embodiment, since moisture due to condensation is appropriately drained, there is no possibility that moisture due to condensation will freeze even if the cold storage agent 90 is frozen.

The cool storage agent chamber 40 is cooled by a cooling device such as the compressor 21 that freezes the cool storage agent 90 and the cooling fan 35, and the cooling fan 35 is provided near the center of the upper portion of the cool storage agent chamber 40. Since the position of the cooling fan 35 corresponds to the vicinity of the central portion of the shelf network 60, a space is provided between the shelf network 60 and the cooling fan 35, so that it is easy to circulate the cool air.
The shelf network 60 is formed of a linear member. The cold air of the cool storage agent 90 is easily transmitted into the space.
