(F) EXAMPLE A high humidity and low temperature storage facility equipped with a storage device according to the present invention will be described below with reference to the drawings. 1 is between the front [opening and closing in 1 part]
2, and the heat insulating box 1 is constructed by filling a space between the inner and outer boxes with a heat insulating material. This insulation box 1
Inside the insulating box body 1, for example, an upper thermal conductive box 6 and an upper thermal conductive box 7 made of stainless steel and having an open front are fixedly installed with a space between them and all the inner wall surfaces of the insulating box body 1. The formed space is used as a cold air passage 8, and the inner sides defined by the upper heat conducting box 6 and the upper heat conducting box 7 are used as an upper storage chamber 9 and a lower storage chamber 10, respectively. In addition, each storage room 9
, 10, the food 12 accommodated in the tray 11 is placed in the vertical direction.
A plurality of net shelves 13A and 13B are provided on which the items are placed.

In the upper part of the upper storage chamber 9, there is a plate made of stainless steel, for example, and a plate for the top plate, which faces the top plate 6A of the upper heat conduction box 6, which is tilted low to the rear, with a small distance therebetween. The upper metal tray 14A has a plate 14A tilted backwards at a low angle of about 7 degrees and is removably arranged. The metal lower support plates 14B, which are opposed to each other with a small distance between them, are removably arranged with a low inclination toward the rear of about 7 degrees.

These upper and lower top plate condensers 14A and 14B have earthen walls on the front and both sides and are dish-shaped, and the shelves 13A,
The lower end portion located after the rear end of 13B is bent downward to form draining portions 14C and 14D.

The top plates 14A and 14B are supported on support rails 15 fixed to both side walls of the heat conducting boxes 6 and 7 so as to be freely drawn out.

Next, the shelf tray device will be explained. The shelf tray is installed on the upper shelf 1 as shown in Figures 1 and 2.
It is detachably attached to the bottom of 3A. To be more specific, the plate 16 of the shelf tray is close to the lower surface of the shelf 13A, has rising walls on the front and both sides, and has a plate shape with a bottom plate that slopes low to the rear. A drain portion 16A is formed by bending the lower end of the bottom plate located behind the rear end of the shelf 13A downward. At the upper ends of the rising walls on both sides, -
In order to support the board 16 on the shelf 13A, the shelf 13A
A hook that engages with the outer frame forms a portion 16B.

In addition, in the above configuration, the top plate dew tray is the plate 14A, 1
4B and the shelf tray are coated with hydrophilic paint to form a thin layer 17 of hydrophilic paint on the lower surface of the plate 16, as shown in the sectional view in FIG.

In addition, the upper storage chamber 9 and the lower storage chamber 10 are connected to each other by inserting the top plate 7A of the upper thermal conduction box 7 from the bottom plate of the upper thermal conduction box 6, and the lower dew tray is connected to the plate 1.
It communicates via the upper drain vibe 18A facing above 4B, and the outside of the lower storage chamber 10 is inserted from the bottom plate of the upper heat conduction box 7 through the bottom wall of the insulation box 1 and hangs outside the box 1. It communicates via a lower drain vibe 18B.

Furthermore, the top wall of the heat insulation box body 1 and the upper heat conduction box 6 facing thereto
In the cold air passage 8 between the top plates 6A, a unit cover 21 having an air outlet 19 at the front and a suction hole 720 at the rear is disposed as a cooling means. , a refrigerating system evaporator 22 and a cool air circulation blower 23 are housed in front of the evaporator 22 and facing the blowout port 19.

The evaporator 22 is an electric compressor 2 installed on the top wall of the box 1.
4 and a condenser 25 to form a refrigeration cycle. 26 is a condenser air cooling fan.

In addition, a vertical partition plate 27 is disposed in the vertical direction in the cold air passage 8 between the rear wall of the heat insulating box 1 and the rear plate of the upper and lower heat conduction boxes 6 and 7 facing thereto, and a discharge passage 8A is provided. A return passage 8B is formed, and both passages communicate through a lower communication port 28. Furthermore, there is a cold air passage 8 between the bottom plate of the upper heat conduction box 6 and the top plate of the upper heat conduction box 7.
A horizontal horizontal partition plate 30 with a communication port 29 formed in the front part is disposed therein.

In the above configuration, the cold air that has undergone heat exchange in the evaporator 22 is discharged from the air outlet 19 to the cold air passage 8 by the blower 23, and is circulated in the path shown by the arrow in FIG. After cooling, it passes through the connection 029, cools the upper heat conducting box 7, passes through the return passage 8B from the lower connection port 28, and is returned to the evaporator 22 again from the suction port 20. As a result, the air in the upper storage chamber 9 and the lower storage chamber 10 is indirectly cooled via the upper and lower heat conducting boxes 6 and 7. Such an indirect cooling method for the storage compartments 9, 10
It is highly effective as one of the requirements for maintaining 0 at high humidity.

By the way, dew condenses on the inner surfaces of the heat conduction boxes 6 and 7 due to entry of outside air by opening and closing the door 2 and evaporation of moisture in the food 12.
In particular, the condensed water that falls from the top plates 6A and 7A falls onto the plates 14A and 14B in the upper and lower condensation pans, respectively, and flows from the draining parts 14C and 14D at the lower edges onto the bottom plates of the thermal conductive boxes 6 and 7. Fall. The dew that has fallen onto the bottom plate of the upper heat conduction box 6 further passes through the upper drain pipe 18A and falls onto the lower dew tray plate 14B, and from the drain portion 14D at the lower edge of the lower dew tray, the dew drops onto the bottom plate of the upper heat conduction box 7. The water falls onto the bottom plate and is drained to the outside through the lower drain vibe 18B. Therefore, it is possible to prevent the condensed water that has fallen from the top plates 6A, 7A from dripping onto the food 12 placed on the upper shelf 13A.

In addition, although the inner surfaces of the thermal conductive boxes 6 and 7 are not the same, dew condensation also occurs on the top panel dew pans on the plates 14A and 14B.
The dew condensed on the lower surfaces of plates 14A and 14B spreads uniformly over the entire lower surface of plates 14A and 14B without turning into water droplets due to the action of the thin layer 17 of hydrophilic paint that has water-wetting and water-retaining properties. Moreover, the dew tray flows backward due to the tilting action of the plates 14A and 14B, and falls onto the bottom plate as it is pulled by the action of the draining portions 14C and 14D.

By the way, the humidity is on the top plate 6A of the heat conduction box 6 and 7.

Dew condensation not only occurs on the shelves 13A and 13B, but also on the tray 11 when the food 12 is placed on the tray 11 as in the embodiment. Of these, the upper shelf 1
The condensed water adhering to the trays 3A and the upper tray 11 becomes water droplets and falls onto the plate 16 of the shelf tray, and then falls onto the bottom plates of the heat conduction boxes 6 and 7 from the draining portion 16A at the lower edge. . The subsequent waste water treatment is the same as that for the plates 14A and 14B, so the explanation will be omitted.

In this way, it is possible to prevent the condensed water that has fallen from the upper shelf 13A and the upper tray 11 from dripping onto the food 12 placed on the lower shelf 13B.

In addition, in the dew pan for shelves, dew condensed on the bottom surface of the board 16 does not become water droplets due to the action of the thin layer 17 of hydrophilic paint, and the dew pan spreads uniformly over the entire bottom surface of the board 16. flows backward due to the tilting action of the plate 16, and the draining portion 16A
It falls onto the bottom plate as if being pulled by the action of.

Note that since the condensed water adhering to the lower shelf 13B and the lower tray 1 falls onto the bottom plates of the thermal conductivity boxes 6 and 7, there is no need to provide a dew catcher on the lower shelf 13B.

FIG. 4 is an enlarged view of the lower surface of the plates 14A and 14B for the top plate and the plate 16 for the shelf, and grid-like stripes 27 are formed on the lower surfaces by means such as Scotch Brite. This is what I did. In this case, due to the action of the grid-like stripes 27, the so-called capillary phenomenon, the dew condensed on the bottom surfaces of the plates 14A, 14B, and 16 does not become water droplets in each dew pan, as in the case where the above-mentioned hydrophilic paint is applied. , wastewater treatment will be consulted.

Note that the number of shelves is not limited to the embodiment, and when the number of shelves increases, plates will be provided as shelf trays except for the lowest shelf. Further, the shape and material of the plate for the dew plate are not limited to those in the embodiments, and can be changed as appropriate.

(G) Effects of the Invention As described above, the present invention provides a high-humidity, low-temperature storage in which the storage room has multiple shelves, the lower side of the top plate of the thermal conductivity box and the lower part of the shelves except for the lowest shelf. Since the plates of the trays are arranged at an angle, water droplets falling from the top plate of the heat conducting box and water droplets falling from the shelves will not drip onto the food placed on each shelf. , the quality of food can be maintained well.
