Abstract

PURPOSE:To prevent the fall of dewing water by providing a good heat conduction box in a heat insulation box body to be a stockroom, setting to incline a metal-made drip pan in the upper part of the stockroom and forming lattice- like streaks on the lower face thereof. CONSTITUTION:A gap with the wall face of a heat insulation box to fix an upper good heat conduction box 6 and a lower good conduction box 7 so as to form a cold passage 8 in the heat insulation box body 1 provided with an open and close door 2. A metal-made upper drip pan 12 opposed to a top board 6A of the upper good heat conduction box 8 at a small interval are provided to incline low backward. Lattice-like streaks are formed on the lower face of the drip pan 12. A drip pan 13 is also provided. As the result, dewing water of the top board of the good heat conduction boxes is received with the use of the drip pan and dewing on the lower face of the drip pan is spread on the whole face of the lower face with the use of capillary action of the lattice- like streaks to flow down along the inclination on either. Accordingly, dewing water drops do not produce for storage foods.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a high-humidity, low-temperature storage chamber that indirectly cools a storage chamber defined inside an insulated box and maintains the storage chamber at high humidity. In particular, the roof pan located above the storage room is related to the improvement of the board.

(B) Prior art As a prior art, Japanese Utility Model Publication No. 60-2555 discloses that a plate is provided on the ceiling of a cooler box to receive condensed water dripping from the upper wall of the cooler box. A device for a humidifying refrigerator has been disclosed, which is characterized in that a plate has a peripheral edge bent upward and a plurality of cold air passage holes are formed therein.

(C) Problems to be Solved by the Invention According to the device of the conventional dew pan, the condensed water dripping onto the dew pan is treated as drainage without falling into the cooling chamber, but the bottom surface of the dew pan The problem remains that the condensed water falls into the cooling chamber as water droplets and wets the food.

In view of these problems, the present invention provides a high-humidity, low-temperature storage warehouse equipped with a dew tray that reliably protects stored foods from dew condensation.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a heat insulating box with an opening/closing door at the front opening, which is provided with a spaced apart from the inside of the insulating box for good heat conduction. A box is disposed, and the inside of the heat conduction box is used as a storage chamber, and a cooling means is disposed in the space between the heat insulation box and the heat conduction box to indirectly cool the storage chamber. In the high-humidity, low-temperature storage, a metal condenser facing the top plate of the thermally conductive box at a distance from the upper part of the storage chamber is arranged with a plate inclined low to the rear; It is a high-humidity, low-temperature storage chamber with grid-like stripes formed on the bottom surface of the board.

(E) Function According to the present invention, when the heat conduction box is cooled, the air in the storage room is indirectly cooled through the heat conduction box. On this occasion,
The condensed water that condenses on the top plate of the thermal conductive box and falls from the top plate as water droplets is caught by the plate, and the condensed water is guided backward by the slope of the plate and wets the stored food. Wastewater is treated without any wastewater treatment.

In addition, a small amount of condensed water adhering to the underside of the board spreads over the entire underside of the board without turning into water droplets due to the action of the lattice-like stripes and by the so-called capillary phenomenon. By the action of the stripes and slope of the board, the food is guided backwards, avoiding the stored food, and falls from the lower edge of the board.

(f) Example The high humidity low temperature storage of the present invention will be explained below with reference to FIGS. 1 to 3. Reference numeral 1 denotes a heat insulating box having an opening/closing door 2 at its front opening, and the heat insulating box 1 is constructed by filling a space between the inner and outer boxes with a heat insulating material. Inside the heat insulating box l, a top heat conduction box 6 and a top heat conduction box 7 made of, for example, stainless steel and having an open front are fixed to all the inner wall surfaces of the heat insulation box l with a gap between them. The space formed by this is used as a cold air passage 8, and the inside defined by the upper heat conduction box 6 and the upper heat conduction box 7 is used as an upper storage chamber 9 and a lower storage chamber IO, respectively. . In addition, each storage room 9. A plurality of shelves 11 on which stored foods are placed are arranged in the vertical direction of the IO.

In the upper part of the upper storage chamber 9, there is a metal lower plate 12 facing the top plate 6A' of the upper heat conduction box 6, which is tilted low to the rear, with a small distance. It is installed at a low (sloping) rearward angle of about 7 degrees and is removable.
The metal lower tray 13, which faces the top plate 7A of the upper heat conduction box 7 with a small distance therebetween, has a plate 13 that is tilted rearward by about 7 degrees and is detachably arranged.

These upper and lower deck plates 12 and 13 have molded clay walls on the front and both sides, and are dish-shaped, with the lower edge located behind the rear end of the shelf 11 bent downward. Draining section 12A, 13
It forms A. Furthermore, grid-like stripes 15 are formed on the lower surfaces of the plates 12 and 13 by, for example, Scotchbrite.

The upper and lower plates 12 and 13 are the heat guide boxes 6, respectively.
, 7, and is supported on support rails I4 fixed to both side plates of .

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.
The lower storage chamber IO and the outside are connected to each other through the upper drain vibe 16 facing above 3, and the lower storage chamber IO and the outside are inserted from the bottom plate of the upper thermal conductivity box 7 through the bottom wall of the insulation box 1 and hang down outside the box I. It communicates via a lower drain vibe 17.

Furthermore, the top wall of the heat insulating box 1 and the upper heat conducting box 6 facing it
A unit cover 21 having an air outlet 19 at the front and an inlet 20 at the rear is disposed as a cooling means in the cold air passage 8 between the top plates 6A.
1 houses a refrigerating system evaporator 22 and a cold air circulation blower 8!23 in front of the evaporator 22 facing the outlet 19.

The evaporator 22 is an electric compressor [2
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 l and the rear plate of the upper and lower heat conduction boxes 6 and 7 opposite thereto, and the discharge passage 8A is 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 communication port 29 to cool the upper heat conducting box 7, passes through the return passage 8B from the lower communication 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, 7. Storage room like this9. The indirect cooling method for lO is in the storage room 9.1.
It is highly effective as one of the requirements for maintaining 0 at high humidity.

By the way, dew condensation occurs on the inner surface of the thermal conductive box 6.7 due to entry of outside air by opening and closing the door 2, evaporation of moisture in the stored food, etc.
In particular, the condensed water that falls from the top plates 6A and 7A falls onto the upper and lower condensation plates 12.13, respectively, without wetting the stored food on the shelf 1 from the draining parts 12A and 13A at the lower edges. It falls onto the bottom plate of the heat conducting box 6.7. The dew that has fallen onto the bottom plate of the upper heat conduction box 6 further passes through the upper drain pipe 16 and falls onto the lower dew catcher plate 13, and from the draining portion 13A of the lower edge of the lower dew tray to the upper heat conduction box 7. The water falls onto the bottom plate of the tank, and is drained to the outside through the lower drain pipe 17.

In addition, although not on the inner surface of the heat conduction box 6.7, dew condensation also occurs on the plate 12.13 in the dew pan, and in particular, the dew condensed on the bottom surface of the plate 12.13 forms grid-like streaks. Due to the action of 15, the so-called capillary phenomenon, water does not form into droplets and the dew is collected on the plate 12.1.
The condensation spreads uniformly over the entire lower surface of plate 12.
The streaks 15 and the dew pans of 13 are guided rearward by the action of the inclination of the plates 12 and 13 and fall onto the bottom plate of the drainage section 12A and I3A heat conducting box 6°7.

In addition, as an embodiment of the lattice-shaped stripes 15, as shown in FIG.
Alternatively, as shown in FIG. 4, the dew tray is formed in a grid shape with an angle to the periphery of the plate 12, 13. Also,
Although six embodiments have been described in which the storage chambers are divided into upper and lower sections, the number of storage chambers is not limited to the embodiments.

(G) Effects of the Invention As described above, the present invention provides a metal dew pan that faces the top plate of the thermal conductivity box at the upper part of the storage room with a small distance between the plate and the plate. This is because the dew tray is formed by forming lattice-like stripes on the bottom surface of the plate.

Of course, it is possible to reliably prevent dew from condensing on the top plate of the heat conducting box and falling from the top plate onto the stored food. The condensed dew does not turn into droplets due to the capillary action of the lattice-like stripes, and the dew pan spreads uniformly over the entire bottom surface of the board.
Due to the stripes and slope of the plate, the condensed water flows backwards and falls from the lower edge of the plate, which extremely effectively prevents condensed water from falling onto the stored food. I can do it.
