Description

TECHNICAL FIELD The present invention relates to a high-freshness storage warehouse suitable for storing perishable foods including leafy vegetables in a highly fresh state.

When harvested fruits and vegetables are stored, they are kept fresh by lowering the temperature to suppress respiration and by raising the humidity to suppress transpiration. The necessary temperature range is 1-5°C and the optimum humidity is narrow, about 90-95%, making it difficult to maintain freshness.

Conventionally, there has been proposed a storehouse equipped with a heat exchange type cooler and a sprinkler type humidifier for storage under a low temperature and high humidity environment.
When the internal temperature drops below 10° C., the fan coil of the cooler is likely to be frosted and clogged. In order to avoid clogging, the defrost operation is essential, but if the defrost operation becomes frequent, the internal temperature will rise beyond the above temperature range.
In addition, since the cold air blown out from the cooler is generated by heat exchange, it is dried.

On the other hand, as described in Patent Document 1, the humidifier is usually a water spray type that sprays moisture into the air, and the humidity greatly exceeds 100% near the spraying point and becomes supersaturated. If dew condensation causes water droplets to adhere to the surface of leafy vegetables, the quality of the leafy vegetables is rather deteriorated.

Figure 2 is a perspective view of the louver portion of the cooler of Figure 1; 2 is a perspective view of the air washer of FIG. 1; FIG. Figure 4 is a perspective view of the filling provided in Figure 3; FIG. 2 is an image diagram of blowing out cold air and moisture inside the refrigerator in FIG. 1 ;

A high freshness storage 1 according to an embodiment of the present invention will be described with reference to the drawings.
The storage body 3 of the high-freshness storage 1 is a prefabricated box with heat insulation specifications, and is opened and closed with a door 5. - 特許庁In addition, an air curtain 7 is attached above the door 5, and blows down the air in a plane to block the flow of air inside and outside even when the door 5 is opened. It is designed not to have a large impact.

A unit cooler 9 (indoor unit) as a cooler is attached to the inner surface of the side wall facing the door 5 at the upper center. The unit cooler 9 is covered with a box-shaped housing cover 11, and has a cool air outlet 13 on its front surface, in which a louver 15 is provided. The cool air outlet 13 faces the center side of the inside of the refrigerator. Also, a suction fan (not shown) is provided on the bottom side, so that the air inside the storage is sucked and passed through the unit cooler 9 .
As shown in FIG. 2, a louver 15 is arranged in front of the cool air outlet 13 . The louver 15 is suspended from the ceiling and installed independently from the unit cooler 9. As shown in FIG. In this louver 15, horizontally elongated strips 17, 17, . . . are arranged in the vertical direction. occlude.
The band-shaped plate 17 is slightly curved so that the cross section in the width direction forms a large circular arc shape, and when the cold air blowing port 13 is closed, the concave curved surface 17A faces the inner side.

One end side of a lever (not shown) is attached to each of the belt-like plates 17, 17, . . . The intermediate portion of the lever is pivotally attached to a support shaft 18 that spans the housing cover 11 in the horizontal direction, and the other end is pivotally attached to one operation shaft 19, and the operation shaft 19 is moved up and down. By doing so, the lever rotates about the support shaft 18 to open and close the belt-like plates 17, 17, . . . .

As the plate surface of the belt-like plate 17 approaches the horizontal direction, the cold air blowing port 13 is opened wider, and the blowing amount increases. It is above the side edge 17C. Further, as described above, the concave curved surface 17A always faces the back side, and the concave curved surface effect is also utilized to stably direct the blown air upward as indicated by the arrow. The smaller the opening, the closer the airflow direction is to the vertical direction.
In this way, the louver 15 can be used to adjust the direction of the blown air upward. Although the louver 15 is manually operable, it can of course be electrically operated.

As shown in FIG. 1, the unit cooler 9 is used in combination with the outdoor unit 21 to use the inside of the refrigerator as a refrigerating facility. After the surrounding air is cooled by the latent heat of vaporization of the liquid refrigerant through the coil, it returns to the outdoor unit 21 as a gas refrigerant.
Therefore, cold air (C) is blown out from the cold air outlet 13 . This cold air (C) is generated by a heat exchange system, and part of the water vapor is condensed and removed, and the cold air (C) is dried by that amount.

An air washer 23 is attached to the inner wall of the side portion orthogonal to the door 5 at the upper center. The air washer 23 is covered with a box-shaped housing cover 25, the front of which serves as a moisture outlet 27, and a fence 29 is provided there. The moisture outlet 27 faces the center side of the inside of the refrigerator. A housing cover 25 is suspended from the ceiling.
As shown in FIG. 3, a pair of suction fans 31, 31 are provided on the rear side of the housing cover 25 so that the air inside the refrigerator is sucked and passes through the air washer 23. .

Further, the air washer 23 is provided with water supply and drainage means, and as shown in FIG. The water supply pipe 33 is branched after entering the housing cover 25, and is divided into a comb shape. The comb-like branch tubes 35, 35, . Each comb-shaped branch tube 35 is closed at its axial end, but has a jet hole (not shown) formed on the lower side of the peripheral surface, and water supplied through the water supply pipe 33 is jetted out. It is designed to be ejected downward from the hole. Since the jet water (W) is pressure-fed by a pump (not shown), it is sprayed radially as mist from the jetting holes, expanding the jetting area. A plurality of ejection holes are provided at intervals in one comb-like branch tube 35 .

A drain pipe 37 is also connected to the lower surface of the housing cover 25 . The drain pipe 37 and the water supply pipe 33 are positioned substantially diagonally to each other.
The drain pipe 37 allows the water that has fallen to the bottom of the housing cover 25 to be drained without accumulating.

A filling 39 is accommodated inside the housing cover 25 . As shown in FIG. 4, the filling 39 is in the form of a rectangular block, and is arranged in the middle of the housing cover 25 with a gap from the upper and lower ends thereof. The water ejection action by 35, .
The moisture outlet 27 in the front of the housing cover 25 faces the filling 39, and its upper and lower sides are closed with panels.

In the filling 39, thin plastic sheet materials 41, 41, . The sheet material 41 is press-pressed at random, and when viewed in the thickness direction, the concave surface 41A and the convex surface 41B on one surface side become the convex surface 41B and the concave surface 41A on the other surface side, respectively. .
In addition to the fine unevenness processing described above, large protuberances 43, 43, . . . are formed at predetermined intervals. The convex protuberances 43, 43, . . . The sheet materials 41, 41, . is abutted against the sheet material 41, and the abutting surface is adhered.

As a result, the adjacent sheet materials 41, 41 are connected to each other, and the plurality of sheet materials 41, 41, . . . are integrated into a three-dimensional block.
A gap corresponding to the height of the protruding portion 43 is provided, and since the circumference of this gap is open, air and water can pass between the adjacent sheet members 41, 41. .

The filling 39 is accommodated in the housing cover 25 so that the gap between the adjacent sheet materials 41, 41 is opened in the lateral direction and the vertical direction from the back surface to the front surface, and is arranged in the lateral direction and the vertical direction. used as a passageway.
Therefore, the sprayed water (W) drops from above in the form of mist, and the water that collides with the plate surface of the sheet material 41 flows down and escapes downward.
Air flows through this passage from the rear to the front due to the suction action of the pair of suction fans 31, 31, and the uneven surface of the sheet material 41 disturbs the air flow. .

The turbulent air moves forward while efficiently entraining the falling misty water droplets (D). Among the involved water droplets (D), small ones are partly vaporized while flowing with the air, and large ones fall without being vaporized. By adjusting the capacity of the suction fans 31, 31, the blowing force is suppressed, and the water droplets (D) that have not been vaporized are not scattered from the moisture blowing port 27.例文帳に追加
In this manner, the air washer 23 is configured so that the vaporization method of vaporizing the water droplets (D) into water vapor and humidifying the water vapor proceeds smoothly.

As shown in FIG. 1, a control panel 45 is attached to the outer wall of the storage body 3, and is systemized to control the operation of the unit cooler 9 and the air washer 23 by setting this.

FIG. 5 shows a state in which containers (B) containing leafy vegetables such as cabbage are stacked and stored in the storage body 3, and the unit cooler 9 and the air washer 23 configured as described above are in operation. inside.
Dry cool air (C) is blown out from the cool air outlet 13 of the unit cooler 9 . This cool air (C) is directed to the ceiling of the storage body 3 or the side surface near the ceiling by the wind direction adjustment function of the louvers 15 . That is, it is directed to the container (B) side via a detour, and is not directly directed to the vegetables. In this way, the interior of the storage body 3 can be evenly maintained in a constant temperature atmosphere in which the occurrence of temperature unevenness is suppressed.

A part of the dry cold air (C) goes around to the rear side of the air washer 23, is sucked into the housing cover 25 by the suction fan 31, becomes moisture (M), and is blown out from the moisture outlet 27. It is It should be noted that not only the cold air (C) but also the air around it is sucked in and turned into moisture (M).
In the vaporization method, since the humidity inside the storage body 3 does not exceed 100%, which is the saturation limit, water droplets are prevented from adhering to the vegetables. In addition, since steam is constantly taken into cold air (C) that has progressed in drying and moisture (M) continues to be generated efficiently, the inside of the cabinet 3 is always kept in a constant humidity atmosphere within the range of 90 to 95%. It is possible to maintain without

In addition, since the water from the air washer 23 is prevented from scattering into the inside of the storage body 3, frosting of the unit cooler 9 is less likely to occur, and the frequency of defrost operation is reduced, thereby suppressing temperature rise. be done.
Therefore, it is possible to maintain a constant temperature atmosphere within the range of 1 to 5° C. all the time.
