The present invention relates to a cold water supply device for a refrigerator, and more particularly, in a device in which water in a bucket installed in a refrigerating compartment is supplied through a water supply valve installed outside the door, the water supply valve is opened and closed by an electromagnet, thus being convenient to use. It relates to a cold water supply device of the refrigerator.

In general, the refrigerator comprises a freezer compartment 1, a refrigerator compartment 2, a door 3 and 4 that open and close the freezer and refrigerator compartment 1 and 2, and a refrigeration cycle apparatus as shown in FIG. Compressor (6) for compressing the high temperature and high pressure, an evaporator (7) that condenses and expands in a condenser and capillary tube (not shown), and finally evaporates and cools the surroundings, and a freezing chamber (1) and a refrigerating chamber (2). A circulation fan 8 is provided to circulate internal air to the evaporator 7 to force heat exchange. Meanwhile, a bucket 5 is provided inside the refrigerating compartment door 4, and a valve 9 connected to the bucket 5 is provided outside.

In the conventional refrigerator configured as described above, the freezing and refrigerating chambers 1 and 2 and the air are circulated to the evaporator 7 while the circulation fan 8 is operated to be cooled by heat exchange. In addition, the cooled cold air is circulated to the freezer, refrigerating chamber (1) (2) and the food stored therein is frozen and refrigerated.

On the other hand, water is contained in the bucket 5 provided inside the refrigerating chamber door 4 and foreign matter can be supplied from the outside without opening the door 4. That is, since the water is supplied without opening the door 4, the cold air loss is small and the refrigeration efficiency is improved. In this water supply device, when the valve 9 installed outside the door 4 is pushed by the cup C, the cold water is supplied while the valve 9 is opened.

However, the valve 9 is opened only when the lever 9a for opening and closing the valve 9 is directly connected to the valve 9 and directly presses the lever 9a. At this time, in order to reduce the hips pushing the lever 9a, the lever 9a needs to be formed long. In addition, when the lever 9a is released while the lever 9a is released, the water supply valve 9 is gradually closed because the lever 9a is not quickly restored. Therefore, there is a disadvantage that the water is wasted by supplying more than a predetermined amount of cold water.

The present invention has been devised to solve the above problems, the object of the present invention, the water supply valve is automatically opened when water is applied to supply water, to make it convenient to use and to ensure that the amount of water supply is accurate water saving effect It is to provide a cold water supply device of the refrigerator.

In order to achieve the above object, the present invention, in the device for supplying the water of the water tank installed in the refrigerating chamber without opening the door, the water supply valve having an outlet at the bottom and exposed to the water supply provided on the outer side of the refrigerating chamber, so as to communicate with the outlet A lifting tube placed above the water supply valve, a plunger installed as a spring in the lifting cylinder to block the outlet, and an electromagnet for opening the outlet by raising the plunger when the electric winding is applied to the lifting circumference of the lifting barrel. There is a characteristic in that it is equipped.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 is a side cross-sectional view of the present invention. The same components as in FIG. 1 illustrate the present invention using the same reference numerals. That is, the water supply valve 10 installed above the water supply stand 4a of the refrigerating compartment door 4 and having the inner outlet 11, and the sealing member 17 above the water supply valve 10 so as to communicate with the outlet 11. Plunger 12, which is installed through the spring (12) inside the hoisting tube (12) to block the outlet 11, and wound on the outer circumferential surface of the hoisting tube (12), when electricity is applied, the plunger ( The electromagnet 15 which raises the 13 and opens the exit 11 is provided.

Meanwhile, the packing 16 is installed inside the outlet 11, and the outlet 11 is sealed by contacting the plunger 13 to the packing 16. In other words, the spring 14 forcibly lowers the plunger 13 so as to contact the packing 16. At this time, the outlet 11 is blocked and water is not supplied to the cup 18. When electricity is applied to the Hanfun electromagnet 15, the plunger 13 is raised by the electromagnetic force. At this time, the outlet 11 is opened while water is supplied.

The present invention configured as described above is provided with a water supply valve 10 to the upper side of the water supply (4a). At this time, the elevating cylinder 12 is installed above the water supply valve 10, and the elevating cylinder 12 is provided with an electromagnet 15. Accordingly, when the cup 18 is placed on the drinking fountain 4a and the electric power is applied, the electromagnet 15 is operated to compress the spring 14 by the electromagnetic force, thereby raising the plunger 13 inside the lifting tube 12. In addition, when the plunger 13 is raised, the outlet 11 is opened and water is supplied to the cup 18 through the water supply valve 10 connected to the water tank 5.

On the other hand, when water is supplied to a certain amount of water in the cup 18, the electricity is cut off. At this time, the plunger 13 is released from the electromagnetic force and the spring 14 is restored. Thus, the plunger 13 is quickly lowered by the spring 14 to be restored to block the outlet 11. On the other hand, the lifting barrel 12 is installed on the upper portion of the water supply valve 10 through the sealing member 17 does not leak upward. The plunger 13 is also placed in the packing 16 installed at the outlet 11 so that no leaks occur.

As described above, according to the present invention, if the electromagnet is installed at the top of the water supply valve and electric water is applied, the water supply valve is opened by the electromagnetic force, so water supply is convenient. In addition, when water supply is completed, it is cut off quickly, so it has a water saving effect.
