The control method shown in FIG. 13 is to generate cold water in a state where ice-making is first performed in an ice tray, and the control method shown in FIG. 14 has a difference in that cold water can be simultaneously generated with ice making.

In the ice making and cold water generation step (ST200) of FIG. 14, the water for cold water generation is not supplied while the water for ice generation is made, and the ice is not completely frozen, that is, in the form of icy ice. It means that water is supplied.

The operating state of the cold water supply apparatus according to the present invention configured as described above will be described with reference to the drawings based on ice making and instant cold water generation.

Referring to FIG. 15, in the state where the cold water supply device 1 is installed in the refrigerator, the motor 204 is operated by a control command of the controller 600 to ice the ice, and the water tank 210 is stored in the water tank 210. Water is supplied to the ice tray 100 (ST10).

The controller 600 controls the operation state of the pump 204 so that the water supply amount is supplied to the ice making water level H1. At the same time, the water introduced into the ice making tray 100 by the low temperature cold air generated while the refrigerant moves through the cooling pipe 102 is iced after a predetermined time (ST20).

When the user operates the cold water selection button provided in the dispenser to drink cold water suddenly, the control unit 600 receives the operation signal to operate the pump 204.

When the pump 204 is operated, the controller 600 adjusts the amount of water supplied to the ice tray 100 to be supplied only to the cold water supply level H2.

The water is fed over a large amount of ice defrosted on top of the ice tray 100 via the pump 204 and the first transfer pipe 201. For example, assuming that the temperature of the water watered on the ice is 25 ° C. before watering, the water changes into cold water at low temperature (for example, 5 ° C.) while being instantly heat exchanged with ice at the same time as the water supply (ST30). ).

Water converted into cold water is moved in the longitudinal direction of the ice tray 100 through the upper end of the guide portion 300 located at one end of the ice tray 100, and prevents the heat loss of the cold water during the movement process. The guide portion 300 is positioned above the top of the ice, so that the cold water is stably supplied.

The water is stably supplied to the cup where the user is located through the second transfer pipe 202.

When the cold water supply is completed, the control unit 600 performs the heating by operating the heater 104 to ice the ice (ST40). The controller 400 rotates the ejector 60 in order to ice the iced ice in the heating state, and ices the ice in the ice bank (ST50).

The operating state of the guide unit according to another embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 16, the controller 600 supplies water to the ice tray 100 to ice the ice (ST100). The controller 600 performs ice making so that the water supplied to the ice tray 100 is iced.

After a predetermined time elapses, when the user operates the cold water selection button provided in the dispenser to drink cold water suddenly, the control unit 600 receives an operation signal and sends an operation signal to operate the pump 204. ) Is applied.

Water is moved to the guide part 300 via the first transfer pipe 201 by the pump 104. The guide part 300 is disposed inside the mold of the ice tray, so that the cold air of ice is directly transmitted, and the water supplied is instantaneously changed into cold water (ST200).

The cold water is moved through the second transfer pipe 202 to be supplied to the user, and when the user further operates the cold water selection button, the control unit 600 receives the input and operates the pump 204. The amount of water supplied to the ice tray is adjusted through the rotation speed control of the pump 204.

When all the ice making is completed, the control unit 600 operates the heater 104 for the ice-making (ST300), and then melts the portion of the ice interface located in the ice tray 100, and then performs the ice-making (ST400). .

The guide unit according to the present invention may be installed in an ice bank to generate instant cold water, which will be described with reference to the drawings.

Referring to FIG. 17, an ice bank 2000 is installed below the cold water supply device 1. A plurality of ice is stored in the ice bank 2000, the ice is continuously iced and iced by the cold water supply device (1).

The dispenser 20 receives cold water through the water tank 4100 so that a certain amount of cold water can be supplied at all times to supply cold water to the user. If the amount of cold water is increased and the cold water is insufficient in the water tank 4100, or if the water stored in the water tank 4100 is not in the cold water state, cold water is supplied to the user as follows.

When the user operates the instantaneous cold water button, an operation signal is transmitted to the control unit 400, and the input control unit 400 operates the pump 4300 to supply the water stored in the water tank 4100 to the guide unit 3000. It works.

The pump 4300 supplies water to the guide part 3000 through the first transfer pipe 4210 while the rotation speed is controlled by the controller 600.

In the guide part 3000, cooling is performed while the heat of the water at room temperature is quickly conducted to the outside of the guide part 3000 by cold air generated from ice.

The water is continuously pressurized and supplied by the pump 4300, so that the cool air generated by the ice and continuous conduction occur, and are supplied to the user via the second transfer pipe 4320. Therefore, the user can use the instantaneous generated cold water through the dispenser.

Since the guide part 3000 is also disposed outside the bottom surface of the ice bank 2000, the description thereof will be omitted.

Referring to FIG. 18, before the guide part 3000 is supplied with water, cool air of ice is conducted to the guide part 3000 through a plurality of heat exchange plates 3100.

This is because the contact area with the ice is relatively increased as compared with the case where the guide part 3000 is disposed alone without the heat exchange plate 3100, and the amount of cold air conducted to the guide part 3000 is increased.

When water is supplied into the guide part 3000 in this state, the temperature of the water is rapidly lowered, and cold water is generated. Since the heat exchange plate 3100 is formed in a plate form, ice is closely disposed on the front and rear surfaces, and thus, the ice may be conducted to the guide unit 3000 more effectively, and the generated cold water is supplied to the user. .

The guide part according to the present invention may be further provided with a phase change part into which a phase change material such as water or ice is injected.

Referring to FIG. 19, water or salt water in which a phase is changed by cold air is injected into the phase change part 3200 provided together with the heat exchange plate 3100 described above.

In the case of water or salt water injected into the phase change unit 3200, the ice may be cooled by continuous cold air or maintained at a low temperature near the freezing point. In this case, even when the heat exchange plate 3100 does not have direct or indirect contact with the ice, there is an advantage that the cold air can be delivered to the guide part 3000 for a predetermined time.

That is, when the amount of ice stored in the ice bank 2000 is small, or when an abnormality occurs due to a power failure or a failure, the phase change unit 3200 may continuously supply cold air to the guide unit 3000 for a predetermined time. It becomes possible.

Therefore, when the refrigerator is normally operated, instant cold water supply is performed, and the user can be easily supplied with cold water even when the refrigerator breaks down or malfunctions.

Referring to the drawings, the phase change unit 3200 continuously conducts cold air to the heat exchange plate 3100, and the heat exchange plate 3100 receives the cold air conducted through the phase change unit 3200 to guide water flow. Conduction of cold air to the unit 3000.

That is, the guide part 3000 receives the cold air through the ice located in the upper part and the phase change part 3200 located in the lower part, and instantly converts the water flowing through the guide part 3000 into cold water. Will be.
