DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a humidifying cooler for a refrigerator that applies the principle of a cyclone, and in particular has a cylindrical part that introduces air tangentially and swirls it, and a conical part below the cylindrical part. an air rising inner cylinder is disposed concentrically within the cylindrical portion, a cold water chamber equipped with a spray nozzle for spraying cold water is provided to surround the air rising inner cylinder, and an upper end portion of the air rising inner cylinder is provided. A water droplet swirling and shaking chamber is provided so as to communicate with the water droplet swirling shaker chamber, which sprays water from the spray nozzle onto the air that has been swirled in to remove dust from the air, cool it, and humidify it. The present invention relates to a humidifying cooler for a refrigerator, characterized in that water droplets can be removed by colliding air with the wall surface of a cutting chamber and swirling the air.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, the humidifying cooler in the refrigerator of the present invention (whole not shown) is generally designated by the number 1. Air recovered from inside the refrigerator is introduced into the cylindrical part 3 through the air inlet pipe 2. The inlet pipe 2 is connected tangentially to the cylindrical part 3 so as to constitute a cyclone. An air ascending inner cylinder 4 is disposed within the cylindrical part 3,
Moreover, a conical part 30 is connected to the lower end of the cylindrical part 3, and a dust collection and water collection port 9 is provided at the lower end of the conical part 30. The upper end portion 35 of the air rising inner cylinder 4 communicates with the water droplet shaking-off chamber 5, and further includes an arc-shaped inner swirling shaking-off chamber 32 and an arc-shaped outer swirling shaking-off chamber 34 formed outside thereof via a partition wall. It leads to the air outlet pipe 6 through the. The humidifying cooler 1 is mounted on a pedestal 36
The pedestal 36 houses a water tank 13 equipped with a filter (not shown), a pump 15, and a refrigerator 23. Chilled water enters the refrigerator 23 from a cold water inlet pipe 24, exchanges heat with the refrigerant within the refrigerator 23, and is sent out from a cold water outlet pipe 25. The cooled refrigerant is transferred to the refrigerant delivery pipe 26
The refrigerant is then sent to a cooling corrugated pipe 28 provided in the cooling chamber 17, and after cooling the water in the cooling chamber, the refrigerant is recovered from the refrigerant recovery pipe 27 to the refrigerator 23 and circulated.

Dust and moisture mixed in the air are collected through the dust collection port 9.
The dust is collected in the dust collecting tank 10. tank 1
The water in the tank is observed by the water level gauge 11, and the valve 37 is opened at an appropriate time to drain the recovery pipe 12.
The water is collected from the tank 13. A filter is provided in the tank 13 to remove dust and only water is sent from the pipe 14 to the pump 15 and sent through the rising pipe 16 to the cooling chamber 17, where the water is cooled by the refrigerant. The water is cooled, rises further, and is regulated from the rising pipe 18 to the water volume control valve 19.
The cold water is sent from the pipe 20 to the cold water chamber 7. Cold water chamber 7
are provided on the outer periphery of the air rising inner cylinder 4, and cold water is sprayed from a number of spray nozzles 8 provided in the cold water chamber 7 to the cylindrical part 3 of the cyclone, after humidifying, cooling and removing dust from the air. The dust is again circulated from the conical part 30 to the dust collection port 9. Cooling room 1
7 is arranged on the outer periphery of the cylindrical part 3, and the cooling chamber 1
7 is surrounded by a heat insulating wall, and the conical part 30 and the dust collection tank 10 are surrounded by a heat insulating wall 2.
Surrounded by 2.

The operation in which gas, especially air, is humidified, cooled, dusted, and dripped by this humidifying cooler 1 will be explained. Air mixed with dust collected from inside the refrigerator is introduced into the cylindrical part 3 of the humidifying cooler 1 from the air inlet pipe 2, and since the inlet pipe 2 is attached to the cylindrical part 3 in a tangential direction, the air flows into the cylindrical part 3. It is rotated between the inner wall 29 of the cylindrical part 3 and the outer periphery of the cold water chamber 7 and descends, and while being humidified and cooled by the cooling water from the spray nozzle 8, it collides with dust mixed in the air, and the dust and water are centrifuged. Cylindrical part 3 due to force
The air that falls along the wall surface of the conical part 30 and is collected in the dust collection tank 10, humidified, cooled, and dust removed reverses its direction in the conical part 30, and the air rises through the inner cylinder 4 into a purified air stream. and rises. Although the elevated clean air still contains water droplets,
The water droplets are removed in the next step. That is, the clean air is sent from the upper end 35 of the inner cylinder 4 to the water droplet shaking chamber 5, where it is first collided with the wall surface, that is, the wall 31 of the water droplet shaking chamber, and the water droplets are shaken off and further swirled. It rotates in the inner turning shake-off chamber 32, shakes off water droplets due to centrifugal force, and then collides with the wall surface, that is, the inner wall 33, where it makes a sudden change of direction of about 180 degrees. . This rapid rotation is extremely effective in shaking off water droplets. The air is then sent to the outer rotating shake-off chamber 34, and then sent to the air outlet pipe 6 after completely shaking off water droplets by centrifugal force. The cooled, purified, humidified, and dehumidified air is sent from this air outlet pipe 6 into a refrigerator (not shown). The water that has been shaken off is collected into the dust collection tank through a suitable passage. Thereby, the substance to be cooled in the refrigerator is cooled or stored in a sterile and odorless state without fear of drying out.

As shown in the above configuration, since the functions of humidification, cooling, dust removal, and water droplet removal are provided in one device, there is no need for separate dust removal equipment and water droplet removal equipment as in the prior art, and the refrigerator itself can be used. It can be configured very compactly, has a simple structure, and can be manufactured at low cost. Furthermore, since the flow direction of the air obtained by this humidifying cooler is changed within the water droplet removing device, the air can be completely dehydrated, cooled and humidified to a desired state, and dust can be completely removed. , the material to be stored can be stored in highly desirable optimal conditions.
