Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an indoor cooler that cools agricultural products and the like.

[0002]

[Prior art]

 Generally, when cultivating mushrooms or keeping the harvested vegetables, fruits, fresh flowers, etc. cool, the room temperature is kept low with a cooler. In this case, conventionally, a cooler refrigerator is generally provided outside the cultivation room or the cold storage room, and a cooling coil is attached to the ceiling side of the room. However, when a cooler or piping breaks down, it takes time to repair it, which adversely affects the crops that are cultivated or kept cool, and may die or rot. In the conventional cooler, the cool air outlet is installed on the ceiling side of the wall and blows out in one direction, and the warm air is collected on one wall side and sucked in. Due to poor circulation, the entire room could not be cooled uniformly.

If a new cooler is added due to its low cooling capacity, or if a new cooler is installed when a vinyl house or warehouse is temporarily used as a cold storage box, the piping equipment will be greatly damaged. However, there was a problem that the equipment cost was high and the construction period was long.

[0004]

[Problems to be solved by the device]

 The present invention eliminates the above-mentioned drawbacks and can be easily installed anywhere with a small device and power supply and cooling water, and can evenly cool the room, especially when the cooling capacity is insufficient or temporarily. The present invention provides an indoor cooler suitable for use as a cool box.

[0005]

[Means for Solving the Problems]

 The present invention provides a water-cooled refrigerator in the lower inner part of a hollow rectangular parallelepiped case, an air suction section with air suction ports opened on the four side surfaces in the middle of the case, and above and below the air suction section in the vertical direction. A condenser chamber with a freezing tube penetrating laterally through the multiple plate-shaped fins placed in, and a fan above this condenser chamber is installed so that it faces the cool air exhaust port on the top of the case. It is characterized by that.

[0006]

[Action]

 The indoor cooler of the present invention is moved to a predetermined place in a house or a warehouse, connected to a waterway and a water-cooled refrigerator, and connected to a power source. When the switch is turned on and the indoor cooler is operated, the water-cooled refrigerator operates and the fan rotates. In the water-cooled refrigerator, the refrigerant is cooled by tap water, and this refrigerant flows through the freezing tube into the condenser chamber where the plate fins are cooled. When the fan rotates, the air in the room is sucked into the air suction section from the air suction ports formed on the four sides of the case, and then it rises in the case and is guided to the condenser chamber. Cools while passing along this.

The cooled air is discharged into the room from the cool air exhaust port by a fan so as to be cooled. Therefore, if an indoor cooler is installed in the center of the room, the air in the room will be sucked toward the center from the air suction ports formed on the four sides of the case, and the cooled cool air will be the cool air exhaust port in the center. Since the air is exhausted from the ceiling to the ceiling, the air flow can be averaged and the entire room can be cooled uniformly.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 is a case 1 having a hollow rectangular parallelepiped shape, and a water-cooled refrigerator 2 is provided at a lower part of the inside of the case 1. Further, air suction ports 4 formed in a lattice shape are opened on four intermediate side surfaces 3 of the case 1, respectively, and a hollow air suction portion 5 is formed inside the air suction ports 4. A condenser chamber 6 is provided inside the case 1 above the air suction portion 5. In this condenser chamber 6, plate-like fins 7 arranged in the up-and-down direction are obliquely mounted, and a plurality of plate-like fins 7 are arranged at intervals with a freezing tube 8 arranged horizontally. It meanders in the direction and penetrates.

The freezing tube 8 is connected to a water-cooled refrigerator 2 provided at the bottom of the case 1. This water-cooled refrigerator 2 is composed of a compressor 9, a condenser 10 and the like, and a cooling water inflow port 11 and a drainage port 12 are projectingly provided on the side surface of the case 1, and a hose 13 is connected thereto.

A fan 16 connected to a motor 15 is horizontally mounted above the condenser chamber 6. A circular cold air exhaust port 17 is opened on the upper surface of the case 1, and the fan 16 is mounted inside this. In the figure, 18 is a caster attached to the bottom of the case 1 so that it can be moved by pushing the indoor cooler by hand. Reference numeral 19 is an inspection lid provided on the front plate of the case 1, and 20 is a control panel of the water-cooled refrigerator 2.

When a greenhouse or warehouse is temporarily used as a cool box, the caster 18 is attached to the indoor cooler having the above-mentioned configuration, so that the room cooler is manually pushed to move it to the center of the house or warehouse. Thereafter, the hose 13 connected to the water supply is connected to the inflow port 11, and the hose 13 for drainage is connected to the drainage port 12. A power source (not shown) is connected to the water-cooled refrigerator 2, the switch is turned on, the control panel 20 is adjusted, and the operation is started.

When the indoor cooler is operated, the water-cooled refrigerator 2 operates and the fan 16 rotates. The water-cooled refrigerator 2 is supplied with tap water from the inflow port 11 to cool the refrigerant, and the refrigerant flows through the freezing tube 8 into the condenser chamber 6 where the plate fins 7 are cooled. On the other hand, when the fan 16 is rotated by the motor 15 and the air in the case 1 is discharged upward from the cool air exhaust port 17, the air suction ports 4 formed in a grid pattern on the four intermediate side surfaces 3 of the case 1 ... The air in the room is sucked into the air suction unit 5 from four directions. Further, as it rises in the case 1 and is guided to the condenser chamber 6 and passes along the plate-like fins 7 arranged in the up-and-down direction between them, the cooled plate-like fins 7 are touched and cooled. The cooled air is exhausted into the room from the cool air exhaust port 17 by the fan 16 to be cooled.

Further, since the water droplets are condensed by touching the plate-shaped fins 7, it is possible to dehumidify the inside of the room, and the condensed water droplets are provided by the plate-shaped fins 7 inclined as shown in FIG. Therefore, it is designed to flow down along this surface to allow good heat exchange with air. Therefore, if an indoor cooler is installed in the center of the room, the air in the room will be sucked toward the center from the air suction ports 4 opened on the four side surfaces 3 of the case 1, and the cooled cool air will be in the center. Since the air is blown directly from the cool air exhaust port 17 toward the ceiling, the air flow is averaged and the entire room can be cooled uniformly. In addition, the water-cooled refrigerator 2 and the condenser chamber 6 are integrated, and the pipes are also provided in the case 1 with the casters 18 attached, which makes it easier to move and requires less equipment work than the conventional fixed structure. Even in the unlikely event of a failure, it can be easily repaired.

In the above embodiment, the case where only the condenser chamber 6 is provided for cooling only is shown. However, a heater is provided in the condenser chamber 6 to heat only the heater without operating the water-cooled refrigerator 2. A structure that can be used together as a heater may be used. Further, an air reservoir may be attached to the cool air exhaust port 17 and a large number of blowout pipes may be extended in all directions from this.

[0015]

[Effect of device]

 As described above, according to the present invention, since the water-cooled refrigerator and the condenser chamber are integrated and miniaturized, the power supply facility and the cooling water can be easily installed anywhere as well as inside the room. It is possible to obtain uniform indoor cooling, and it is possible to obtain an indoor cooler suitable especially when the cooling capacity is insufficient or when it is temporarily used as a cool box.
