BACKGROUND OF THE INVENTION The present invention relates to a storage room buried underground.

[0002]

2. Description of the Related Art A storage room buried underground has advantages that the internal temperature is low and changes little, and that space can be effectively used. However, the underground storage has a problem that dew condensation occurs on the storage wall and mold occurs during the high humidity season, which is an obstacle to its spread in households.

On the other hand, an electronic dehumidifier utilizing a thermoelectric module for dehumidifying a relatively small space such as a control panel and various storages has been developed in recent years and is being applied to household dehumidification such as a closet or a shoe box. .

[0004]

[Problems to be Solved by the Invention] However, in general, an underground storage has a tendency to store a large volume and a large volume in comparison with its volume, and moreover, the stored items are infrequently taken in and out, so that air is stagnated. A place is easy to make.

Therefore, if the above-mentioned electronic dehumidifier is easily applied to the underground storage, it is expected that the dew condensation on the storage wall cannot be suppressed or it is partially dried too much.

It is an object of the present invention to provide an underground storage that can uniformly prevent dew condensation from occurring inside.

[0007]

The structure of the underground storage of the present invention has a door on the upper surface and is housed underground in the storage main body.
The inner box having an open upper surface is arranged so as to have a gap between the inner box and the storage main body, and an electronic dehumidifier is arranged near the upper wall portion in the storage main body. To do.

[0008]

[Function] Water molecules are lighter than other molecules in the air,
Since it is easy to collect on the upper part, the underground storage of the present invention in which the electronic dehumidifier is arranged on the upper part is effectively dehumidified. Then, since the inner box is arranged in a nested structure in the storage case body, and a gap is formed between the storage case body and the inner box, the dry air is guided along the gap and along the storage wall. Condensation is less likely to occur on the inner wall of the storage body because it flows. If a large number of ventilation holes are formed in the inner box, the dry air flowing through the gap between the main body of the storage box and the inner box will flow into the space inside the storage box through the ventilation holes of the inner box, The air stagnant area is reduced, and the humidity distribution in the storage is made more uniform.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an underground storage as an embodiment of the present invention. The main body 2 of the underground storage 1 is a rectangular parallelepiped box and has a door 2a on its upper surface. The inner box 3 is a rectangular parallelepiped box having an open top surface and has a smaller size than the storage case body 2, and four legs 3a are provided on the periphery of the bottom surface of the inner box 3. . The legs 3a are fixed to the bottom surface of the storage case body 2 in a state where the inner box 3 is concentrically arranged in the storage case body 2.

In this way, a gap 4 is formed between the inner side surface and the bottom surface of the storage case body 2 and the corresponding outer surface of the inner box 3, and the upper surface of the inner box 3 is the upper surface of the storage case body 2. Since it is located at a lower position than this, the gap 4 formed between the storage case body 2 and the inner box 3 communicates with the space portion 5 in the storage case 1. Further, a large number of ventilation holes 6 are formed in all the wall surfaces of the inner box 3 so as to penetrate in the wall thickness direction.

The main dimensions of the storage case body 2 and the inner box 3 are shown below.

An electronic dehumidifier 10 is provided at the upper corner of the storage main body 2.
Is arranged. The main specifications of the electronic dehumidifier 10 are shown below. Thermoelectric module capacity: Current 3A Voltage 14V Fan: Air volume 1m ³ / min Air pressure 5mm / Aq

As shown in FIG. 2, in the electronic dehumidifier 10, a thermoelectric module 12 is arranged in a rectangular parallelepiped case 11, and a cooling heat sink 13 is heat-conductively connected to the heat absorbing surface of the thermoelectric module 12. The heat sink 14 is thermally connected to the heat generating surface.

The heat radiating heat sink 14 has a size substantially the same as the width of the case 11, and is arranged so as to be in close contact with the side wall of the case 11. The cooling heat sink 13 is shorter than the heat radiating heat sink 14 and has a side wall of the case 11. There is a gap between them. The upper surfaces of the cooling heat sink 13 and the heat radiating heat sink 14 are lower than the upper wall of the case 11 at the same height position, and a space portion is formed above the heat sinks 13 and 14, and the space portion is cooled. An air passage 15 that connects the heat sink 13 side and the heat radiation heat sink 14 side is configured.

The lower surface of the cooling heat sink 13 is located slightly higher than the lower surface of the heat radiating heat sink 14, and a water receiver 16 is provided below the cooling heat sink 13. The water receiver 16 is a box having an open upper surface, has a length equal to that of the heat radiation heat sink 14, and is arranged so that the upper portion of the back surface contacts the heat radiation heat sink 14. Therefore, inside the case 11 below the air passage 15, the heat sink 13 and the heat sink 14 are blocked from each other by the heat sink 14 and the water receiver 16.

The inner bottom surface of the water receiver 16 is inclined so as to be lowered toward the central portion, and a screw hole penetrating in the longitudinal direction is formed in the central portion of the bottom surface. A drain port member 17 for dehumidified water is screwed and fixed to this screw hole. A hose 18 is connected to a connection port projecting downward from the bottom surface of the case 11 of the drain port member 17, and the hose 18 is formed on the side wall of the storage case body 2 through the ventilation hole 6 of the inner box 3. The hose is inserted into the storage case 1 and is buried in the ground 19.

Case 1 facing the cooling heat sink 13
In the front wall of No. 1, air inlets 20 and 21 are opened at a position facing the lower part of the cooling heat sink 13 and at a position above the cooling heat sink 13. An outlet 22 for dry air is opened in the bottom wall of the case 11 directly below the heat sink 14 and a fan 23 is installed in the case 11 at the outlet 22.

The operation of the electronic dehumidifier 10 will be described below. When the thermoelectric module 12 and the fan 23 are energized by a power source (not shown), the cooling heat sink 13 is cooled by the thermoelectric module 12, and when the temperature falls below the dew point temperature, the air is removed from the air. To condense water.

Therefore, the air that has entered the case 11 through the lower suction port 20 comes into contact with the cooling heat sink 13 and is cooled by the cooling heat sink 13 so that the moisture in the air is condensed on the surface of the cooling heat sink 13. When this dew condensation grows and becomes large, it drops due to its own weight, falls on the inner bottom surface of the water receiver 16, flows to the central portion side of the bottom surface, passes through the drainage member 17 of the dehumidified water, and is connected to the drainage member 17. It enters the hose 18 and is discharged through the hose 18 into the ground 19.

The air that has been dehumidified through the cooling heat sink 13 flows into the heat sink 14 through the air passage 15 together with the air that has flowed into the case 11 from the upper air intake port 21 and is discharged by the thermoelectric module 12. After cooling the heated heat sink 14, the discharge port 2
2 is discharged by the fan 23.

The electronic dehumidifier 10 is arranged in the upper corner of the storage 1, and the rear surface opposite to the air inlets 20 and 21 formed on the front wall of the electronic dehumidifier 10 is the storage. The air inlets 20 and 21 are fixed to the side wall of the main body 2 and face the space 5 in the storage case 1. And electronic dehumidifier 1
The discharge port 22 for dry air of 0 faces the gap 4 formed between the side wall of the storage case main body 2 and the side wall of the inner box 3.

Therefore, when the electronic dehumidifier 10 is operated as described above, the air in the space 5 in the storage 1 is dehumidified by the electronic dehumidifier 10, and the dehumidified water passes through the hose 18 to the underground. After being discharged to 19, the dry air is discharged to the gap 4 between the side wall of the storage case main body 2 and the side wall of the inner box 3 from the discharge port 22. The dry air discharged into the gap 4 flows in all directions in the gap 4, and also flows into the space portion 5 in the storage case 1 from the many ventilation holes 6 formed in the inner box 3.

Therefore, since the dry air flows through the gap 4 between the storage case main body 2 and the inner box 3, dew condensation hardly occurs on the inner wall of the storage case main body 2. Further, since the dry air is guided to the gap 4 and flows into the whole of the storage case 1 and flows into the space portion 5 in the storage case 1 from the many ventilation holes 6 of the inner box 3,
Dry air evenly flows into the space 5 in the storage case 1 so that there is no place where air stagnates in the storage case 1 and the humidity distribution in the storage case 1 is made uniform.

Table 1 shows the results of comparing the humidity distribution in the storage and the presence or absence of dew condensation on the inner wall of the underground storage different from the underground storage of the present invention. The humidity measurement position in the storage case 1 is shown in FIG. In FIG. 3, is a measurement position. The test period is June. The electronic dehumidifier and the underground storage used have the same structure as described above. However, FIG. 3 shows the position of the electronic dehumidifier and the inner box in the embodiment.

[0025]

[Table 1]

As shown in Table 1, the underground storage of the present invention has a small humidity distribution in the storage and does not condense on the inner wall.
On the other hand, even if the electronic dehumidifiers are the same, in Comparative Example 1 in which the positions are low and the air inlets and outlets are different, or Comparative Example 2 in which the inner box is not provided, the humidity distribution varies and dew condensation occurs on the inner wall.

[0027]

As described above, according to the underground storage of the present invention, since the electronic dehumidifier is arranged at the upper part of the storage, the dispersion of the humidity distribution in the storage is reduced, and the storage is also reduced. Since the dry air flows in the gap between the main body and the inner box, dew condensation does not easily occur on the inner wall of the storage.
