ある。 In general, low-temperature storage for storing perishables such as vegetables, root vegetables, fruits, and yeast must be managed to minimize temperature changes and prevent moisture evaporation. However, this type of conventional low-temperature storage has the sole purpose of maintaining a predetermined low temperature, and its structure is
It has a nearly sealed structure and is cooled by an air cooling system that uses Freon gas. For this reason, the air inside the refrigerator condenses moisture when it comes into contact with the cooling pipes, and then the temperature rises due to the amount of heat brought in by the stored materials and the influence of the outside air.As a result, the inside of the refrigerator is always dry, and the stored materials gradually become hydrated. This results in loss of freshness and dryness. On the other hand, the solidified water falls down as drops,
It is well known that since the surrounding area gets wet, mold, etc. that are resistant to low temperatures can grow, making it difficult to manage the refrigerator.

In order to prevent this, products are packaged with thin films such as vinyl, but it is impossible to completely prevent the above phenomenon. A method has been proposed in which the container is cooled by dropping the container along a line and using cold water, but this method has the disadvantage that the interior of the refrigerator gets wet and cannot be applied to general products.

た点を特長とするものである。 The present invention aims to eliminate such drawbacks of conventional devices, and the refrigerator has an inner panel with a cooling water flow pipe fixed to the inner panel, so that the coolant flow pipe is connected to the lowest temperature part of the refrigerator. The feature is that a diaphragm is installed at a position away from this inner panel, and the inside of the diaphragm is used as a storage space. The refrigerator is equipped with a gas-liquid spray contact device outside the refrigerator to remove air (or inert gas) from inside the refrigerator. The air, etc. is cooled by directly contacting it with a cold liquid in the above-mentioned gas-liquid atomization contact device, and at this time, the temperature of the gas is adjusted and humidified to form a gas saturated with water at a low temperature. The flow is refluxed into the chamber through a reflux pipe, and the withdrawal pipe and the reflux pipe are connected by a bypass pipe, and the bypass pipe includes:
A ventilation volume control device that works with the temperature and humidity detection device inside the refrigerator is installed to control the gas volume by passing some or all of the gas returned to the refrigerator through a bypass, thereby regulating the temperature of the indoor gas. The feature is that it controls humidity.

collides with the partition plate 15 and panel 14 by changing direction and colliding with the partition plate 15 and panel 14
It flows through the narrow space 21 between the casing 11, descends downward, collides with the bottom surface 19, changes direction, merges with new cold air introduced from the cold air guide opening 17, and rises in the center of the housing 11 (Fig. (the arrow inside indicates this), and the above procedure is then repeated to cool the items stored within the enclosure. (Please note that the storage shelves inside the housing have a shape and structure that has low air flow resistance, and the items stored on the shelves are carefully placed so that the air flow is not obstructed.) There is no difference from normal refrigeration in that it is stored on top.)

には、冷風中の水分が露結するおそれはない。 During the above-mentioned air circulation, a portion of the cold air is discharged from the discharge opening to the cold air device described below.
Furthermore, since the panel 14 is cooled by the pipe 13 through which cooling water flows, the temperature is lower than that of the partition plate 15 which is cooled by cold air (because the cold water is lower in temperature than the cold air). Therefore, the moisture contained in the cold air circulating (or circulating) within the housing 11 is
Although dew condensation (condensation) occurs on the panel 14, there is no risk of moisture in the cold air condensing on the partition plate 15.

管４７を経て冷蔵庫１に戻ることになる。 The air from which dirt and the like have been removed by the cyclone 34 is sent to the spray cooler 36 via the conduit 33. The spray cooler 36 has a cyclone 34 on the side.
The air conduit 33 communicating with is opened, the reflux pipe 37 is opened and fixed above, and the cooling pipe 38 is installed around the reflux pipe 37 in the spray cooler 36, and this is branched to form a large number of spray ports 39a, 39b. ... are opened into the spray cooler 36, and the cold water pipe 38 is communicated with the cold water tank 10. A large amount of cold water that is constantly cooled to a predetermined temperature (for example, about 3° C.) is stored in the cold water tank 10, and the cold water is passed through the pump 29 into small droplets from the spray ports 39a, 39b, and then sent to the spray cooler. It squirts inside 36. Therefore, the spray cooler 36
The air that has entered comes into contact with water droplets from the ejection pipes 39a, 39b, etc., and exchanges heat quickly and efficiently.
Excess moisture due to cooling is condensed and deprived of water, and insufficient moisture is humidified and saturated at a temperature approximately equal to the cold water temperature, and exits from the reflux pipe 37. On the other hand, the water that has been deprived of heat dissolves or suspends odors, dust particles, etc. in the refrigerator, and since it does not drip when used repeatedly, it is passed through the conduit 41 to the filter 42 and passed through the conduit 4.
1' to the cold water tank 10. For this reason, the filter 42 is preferably a normal filter made by layering an adsorbent material such as activated carbon, silica clay, acid clay, or ion exchange resin. The cooled air leaving the spray cooler 36 still contains some droplets and is moist, so it is completely dehydrated by the second cyclone 43. Therefore, only the dehydrated and saturated humid air returns to the refrigerator 1 via the reflux pipe 47.

6. The water passes through the second cyclone 43, where it is purified, cooled, and refluxed into the refrigerator 1. When the temperature inside the refrigerator 1 falls to a predetermined temperature, the temperature detectors A 1 and A 2 detect this and inform the operating section 50 to rotate the ventilation control device 49, so that the air in the reflux pipe 47 is diverted to the bypass pipe 48. ,
It circulates through the suction pipe 25, the fan 3, the first cyclone 34, the spray cooler 36 and the second cyclone 43, and enters the refrigerator 1 at all or only in a limited amount. Also, when the temperature inside refrigerator 1 rises,
The ventilation amount control device 49 stops, the air returns to the previous state, and the air flows only into the refrigerator 1. By doing this, a constant temperature is maintained inside the refrigerator, but the present invention also adjusts the humidity inside the refrigerator by adjusting the temperature of the cooling pipe 13. For this reason, when the humidity detectors B 1 and B 2 are adjusted to a predetermined humidity scale and the temperature of the cooling pipe 13 is adjusted, the relative humidity inside the refrigerator fluctuates, and the humidity detectors B 1 and B 2 detect this fluctuation. Since the operating unit 50 is activated, the humidity inside the refrigerator can be controlled for the same reason as described above.

できる。 FIG. 3 shows a shower 60 for washing an inert gas (for example, an inert gas consisting of CO 2 and N 2 is obtained by completely burning oil or the like). Inert gas generated by an inert gas generator (not shown) is introduced into the crease 60 from a lower introduction pipe 61 of the shower 60, and washing water is sprayed from above from the pipe 62 to perform washing. After cleaning, the inert gas is discharged from the take-out pipe 63 at the upper end of the shower 60.
(In Fig. 3, 64 is the filling, 65
2 indicates a drain pipe), and after removing dust with a fountain γ in a cyclone 66, the inert gas that has been cleaned and dust removed is discharged from the take-out pipe 67 to
from the point into the device. Note that in order to create this inert gas atmosphere, the air inside the cooling device must be exhausted at the beginning, but this is done by injecting the inert gas into the cooling device from point By extracting air and sequentially replacing the gas in the device with inert gas, the entire cooling device can finally be made into an inert gas atmosphere.

多くの利点を有するものである。 Furthermore, the benefits obtained by the present invention are not limited to the above-mentioned benefits. When rapid cooling is desired, it is sufficient to increase the rotational speed of fan F and pump P to increase the amount of cooling air recirculated, or to stop pump P. Steam is ejected from the steam pipe 14 and mixed with the circulating air to reach a desired temperature and sterilize the inside of the refrigerator 1, piping, and other devices, and the air inside the refrigerator 1 is washed with cold water during circulation. Because it is purified, no strange odor accumulates inside the refrigerator, preventing scents from transferring to stored items. Furthermore, since a large amount of cold water is always stored in the cold water tank 10, it is possible to meet urgent needs, and there is no need to prepare a particularly large compressor 5, resulting in savings in equipment investment. This also has many advantages, such as lower power consumption and lower maintenance costs.
