[First Embodiment]

The instantaneous cooling apparatus using the refrigeration cycle according to an embodiment of the present invention shown in FIGS. 1 and 4

A raw water supply unit;

A water storage tank 12 in which an inlet 10 through which a fluid at room temperature (referred to as purified water or mineral water) (hereinafter referred to as "purified water") flows and an outlet 11 through which the fluid is discharged are formed;

The cooling water is circulated spirally so as to increase the cooling efficiency by increasing the contact area with the outer periphery of the water storage tank (12). The refrigerant is circulated by the refrigerating cycle and the fluid of the water storage tank (12) A cooling coil 13 for cooling the purified water;

A compressor (3) connected to the outlet side of the cooling coil (13) to compress the returned refrigerant;

A tube (17) installed in the water storage tank (12) and into which a refrigerant in a condensed state flows from a condenser (4) for condensing the refrigerant compressed in the compressor (3);

And an expansion valve (5) for supplying the liquid coolant discharged after heat exchange in the tube (17) of the water storage tank (12) to the cooling coil (13).

Although not shown in the figure, the cooling coil 13 may be formed as a coil spring inside the water storage tank 12.

The raw water supply unit includes a raw water supply pipe L1 for supplying purified water to an inlet of the water storage tank 12, a water filter 21 formed in the raw water supply pipe L1, a pressure reducing valve 20, And a solenoid valve 22 that opens and closes the valve L1.

A drain pipe (L2) is connected to the raw water supply pipe (L1) passing through the pressure reducing valve (20). The water discharge pipe L2 induces drainage when the solenoid valve 22 is turned off.

The reservoir 12 includes a fluid guide member 15 formed of a spiral guide plate 14 for guiding the fluid flowing into the reservoir 12 through the inlet 10 toward the outlet 11;

An ice wall 16 formed on the inner wall of the water storage tank 12 by the refrigerant of the cooling coil 13;

A refrigerant passage formed in the center of the fluid guide member 15 for exchanging heat with refrigerant in a condensed state, which is moved from the condenser 4 to secure a fluid flow path through which the fluid moves in the water reservoir 12 A tube-shaped tube (17) which is moved to the expansion valve (5);

And a water temperature sensor 18 installed inside the water storage tank 12 to sense water temperature inside the water storage tank 12.

The ice wall 16 is formed by cooling the purified water because the cooling action for cooling the purified water of the water storage tank 12 is continuously performed by repetitive operation of the freezing cycle.

The refrigerant in the high-temperature and high-pressure state, which is moved from the compressor (22), is conveyed to the condenser (4) through the pipe (32).

Thereafter, the refrigerant of high temperature and high pressure is transferred to the tube inlet pipe 172, supplied to the tube 17 in the water storage tank 12, and then heat-exchanged.

Thereafter, the cooled refrigerant is delivered to the condenser 4 through the tube discharge pipe 174 and condensed into a liquid phase.

Thereafter, the refrigerant condensed in the condenser 4 is supplied to the expansion valve 5 to expand the refrigerant in the condensed state to lower the pressure.

The refrigerant transferred from the expansion valve 5 is cooled by mutual heat exchange with the coolant of the water storage tank 12 through the cooling coil 13 surrounding the outer surface of the water storage tank 12, The cooling coil 13 serves as the evaporator 6 of the refrigeration cycle.

Thereafter, the refrigerating cycle returned from the cooling coil 13 is repeated in the compressor 3 to compress the high-temperature and high-pressure gas.

Such a refrigeration cycle is a technical content used in the related art, and thus a detailed description thereof will be omitted.

Hereinafter, the operation of the instantaneous cooling apparatus using the refrigeration cycle according to the first embodiment of the present invention will be described.

Raw water such as tap water is purified by the water filter 21 to filter foreign matter contained in the raw water.

The purified water passes through the solenoid valve 22 which is turned on after passing through the pressure reducing valve 20 and then passes through the inlet 10 of the water storage tank 12 and flows into the water storage tank 12, Respectively.

The purified water flowing through the inlet 10 and flowing into the reservoir 12 forms a spiral trace along the spiral guide plate 14 of the fluid guide member 15 provided in the reservoir 12, .

At this time, as the refrigeration cycle is activated, the high-temperature, high-pressure gaseous refrigerant compressed by the compressor 22 passes through the condenser 4 and the expansion valve 24 and flows into the cooling coil 13 ). ≪ / RTI >

Therefore, the purified water is cooled by the mutual heat exchange between the refrigerant supplied to the cooling coil 13 spirally wound on the outer periphery of the water storage tank 12 and the purified water in the water storage tank 12.

The refrigerant of the cooling coil 13, which is heat-exchanged with the purified water, is returned to the compressor 22 repeatedly.

As described above, the constant of the water storage tank 12 is cooled to a predetermined temperature by heat exchange with the refrigerant of the cooling coil 13, and since the cooling action is continuously repeated, the water of the water storage tank 12 is frozen and stored in the water storage tank 12 An ice wall 16 is formed.

The ice wall 16 gradually becomes thicker as time elapses and extends toward the center of the water storage tank 12, so that the constant flow passage inside the water storage tank 12 becomes narrow.

The high temperature condensation heat generated by the refrigeration cycle is supplied to the tube 17 provided at the center of the water storage tank 12 by the detection signal of the water temperature sensor 18 provided in the water storage tank 12.

Therefore, even when the ice is formed in the water storage tank 12, the ice storage around the tube 17 is melted by the high-temperature condensation heat supplied to the tube 17, so that the constant flow passage can be secured.

The condensed refrigerant supplied to the tube 17 is returned to the expansion valve 5 or the condenser 4 after heat exchange with the fluid in the water storage tank 12.

Therefore, a constant flow passage can be secured between the inlet (10) and the outlet (11) of the water storage tank (12). This makes it unnecessary to use a heater (not shown) for melting the ice to ensure a constant flow passage in the water reservoir 12 when the water is formed in the water reservoir 12.

When the condensation heat is supplied to the tube 17 to dissolve the ice, the condensation heat generated by the condenser 4 of the refrigeration cycle provided in the water purifier is supplied to the water tank 12 It is possible to reduce the number of components and to reduce the cost cost owing to the simplification of the structure of the instantaneous cooling apparatus.

Part of the condensation heat transferred from the condenser 4 is used for defrosting the ice by heat exchange with purified water in the water storage tank 12 through the tube 17 so that the condensing efficiency of the condenser 4 can be improved The size of the condenser (heat sink) can be made compact.

In the case where the operation of the refrigerating cycle is stopped and the purified water in the reservoir 12 is moved toward the discharge port 11 along the spiral guide plate 14 of the fluid guide member 15, The purified water of the purified water 12 passes through the ice wall 16 of the water storage tank 12 and moves toward the discharge port 11,
