DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 1 is a structural diagram of one embodiment of the present invention. Reference numeral 1 is a compressor, 2 is a condenser, 3 is a fan for cooling the condenser, 4 is a throttle device, and 5 is an evaporator for cooling, which constitutes a refrigeration cycle. 6 is an air pump, 7 is an air pipe connected to the air pump 6 and having a hole in the side wall of the inside of the container 8, and water 9 is put in the container 8 as brine. The air pipe 7 is provided below the evaporator 5 near the bottom of the container 8 together with the evaporator 5.

A and B are objects to be cooled such as can juice and can beer. The operation of the cooling device configured as described above will be described below. The refrigeration cycle operates and the temperature of the evaporator 5 drops, and the temperature of the water around the evaporator 5 drops. By the way, the air sent by the air pump 6 comes out from the hole of the air pipe 7 and becomes bubbles to rise while passing through the evaporator 5. Due to the rise of the bubbles, the water around the bubbles is drawn and rises, and the cooled water around the evaporator 5 also rises, and new uncooled water is supplied to the periphery of the evaporator 5. In this way, the water in the container is circulated by the rise of the bubbles. Further, water around the objects to be cooled A and B is also moved to accelerate cooling.

FIG. 2 is a structural diagram of another embodiment of the present invention. Reference numeral 10 is a cylindrical pipe having an air outlet of the air pipe 7 ′ arranged at the lower end.

The operation of the cooling device having the above structure will be described below. The refrigeration cycle operates and the temperature of the evaporator 5 decreases, and the temperature of the water around the evaporator 5 decreases and tends to stay at the bottom of the container 8. However, since the outlet of the air pipe 7 ′ is arranged near the bottom of the container 8, the air sent out rises in the pipe 10 and moves to the container 8
The low temperature water that stays near the bottom of the pipe is carried to the upper end of the pipe 10. Since the upper end of the pipe 10 is near the water surface of the water 9, the water at the bottom is carried to the water surface, and the water is circulated.

FIG. 3 is a structural diagram of another embodiment of the present invention. The evaporator 5'is arranged inside a cylindrical pipe 10 'with the air outlet of the air pipe 7'at the lower end.

The operation of the cooling device having the above structure will be described below. Since the outlet of the air pipe 7 ′ is arranged near the bottom of the container 8, the discharged air rises in the pipe 10 and moves the water retained near the bottom of the container 8 to the upper end of the pipe 10 ′. Carry. The water carried at this time rises while being cooled by the evaporator 5'of the refrigeration cycle and is carried near the water surface to circulate a large amount of water up to the bottom and the water surface. Efficient cooling is performed because heat is exchanged with.

FIG. 4 is a structural diagram of another embodiment of the present invention. Reference numeral 11 denotes a drainage cock provided near the bottom of the container 8, and in order to cleanly cool the objects A and B to be cooled, when the inside of the container 8 is cleaned and drained, the water 9 Drains easily.

FIG. 5 is a structural diagram of another embodiment of the present invention. Reference numeral 12 is a hose that communicates with the inside of the container 8 near the bottom of the container 8. Reference numeral 13 is a hose stopper that detachably holds the tip of the hose 12 when the hose 12 is held by the hose stopper 13. Is located above the water surface of the water 9 in the container 8. Since it is configured as described above, the hose 12 is held and used by the hose stopper 13 during the cooling operation, and after cooling is completed, the inside of the container 8 is cleaned and drained in order to cool the objects A and B to be cooled cleanly. In that case, the hose 12 can be removed by simply removing the hose 12 from the hose stopper 13 and lowering the end of the hose 12 to the place of the drainage facility.
Furthermore, drainage of the water 9 is facilitated.
