As shown below in FIG. 3 , the ice maker according to the present invention includes a refrigerant supply pipe 200 having a plurality of ice-making fins through which refrigerant gas is supplied and circulated, and the refrigerant supplied to the supply pipe 200 It includes a refrigerant discharge pipe 400 for discharging refrigerant gas.

Referring to FIGS. 3 and 4 , the refrigerant discharge pipe 400 is provided inside the refrigerant supply pipe 200 to supply and discharge the refrigerant in an integrated structure.

In addition, the refrigerant supply pipe 200 has an open inlet through which the refrigerant gas 3 is supplied, and a closed pipe shape at the opposite side of the inlet.

In addition, the refrigerant discharge pipe 400 is a hollow pipe with both ends opened, and is stacked in a state in contact with the upper part of the refrigerant supply pipe 200 on the opposite side of the ice making pin 250, so that the width between the two refrigerant pipes is reduced to the refrigerant supply pipe ( 200), the left and right widths of the ice maker can be minimized, so that the ice maker 100 can be slimmed down.

In addition, the distal end 402 of the refrigerant discharge pipe 400 is coupled and connected to the coupling end 510 of the refrigerant discharge exterior 500, and the cross-sectional shape of the coupling end 510 of the refrigerant discharge exterior 500 is as described above.

3(b) and (c) are formed so that the end 402 of the refrigerant discharge pipe 400 is inserted into the coupling end 510 of the refrigerant discharge pipe 500, but the refrigerant discharge pipe is formed as necessary. It is natural that the end portion 402 of the refrigerant discharge pipe 500 of the refrigerant discharge pipe 500 may be formed so as to be coupled to the outside of the coupling end 510.

Of course, at this time, the refrigerant discharge pipe 400 is formed to have a smaller outer diameter than the outer diameter of the refrigerant supply pipe 200 and is welded to the outer surface of the refrigerant supply pipe 200 or provided by inserting the refrigerant discharge pipe 130 into the refrigerant supply pipe 200. It could be.

In addition, a plurality of ice-making pins 250 communicating with the refrigerant supply pipe 200 protrude in the same direction at regular intervals at a lower portion of the outer circumferential surface of the refrigerant supply pipe 200 .

A partition 300 is installed inside each ice-making pin 250 to partition an inner space between the ice-making pin 250 and the refrigerant supply pipe 200 .

In addition, the partition 300 has an end spaced apart from an inner end of the ice-making pin 250, and the partition 300 is welded and fixed to the inside of the ice-making pin 250, and the partition 300 is fixed to the ice maker. Preferably, the pin 250 is inserted into the refrigerant supply pipe 200 and fixed by welding.

Therefore, the refrigerant gas supplied to the refrigerant supply pipe 200 is supplied along the refrigerant supply pipe 200 as shown by the arrow in FIG. It moves to the inner end of the refrigerant 250, then goes around the partition 300 and is supplied to the other side of the ice-making pin 250, and then moves out of the ice-making pin 250 and moves along the refrigerant supply pipe 200 again. The supply route is repeated.

As described above, the refrigerant supply pipe 200, the ice making pin 250, the partition 300, and the refrigerant discharge pipe 400, which are components of the ice maker, may be made of copper, stainless steel, or aluminum.

By uniformly circulating the inside, the efficiency of the ice maker is improved and there is an effect of uniformly producing ice without any variation in size.

Referring to FIG. 2 , in the conventional ice maker, since the first side surface and the second side surface of the fitting groove are flat or the cross section of the refrigerant discharge pipe is circular, a gap is generated between the first side surfaces.

In addition, since there is a difference in the radius of curvature of the lower fitting surface and the corresponding upper surface and the radius of curvature of the outer circumferential surface of the refrigerant discharge pipe, a gap is formed in this part as well, so that the refrigerant leaks through the gap (G) and the refrigerant uniformly penetrates the inside of the ice making pin. There was a problem in that the size of the ice generated from the ice-making pins was not circulated, and the ice-making time was also different.

Therefore, the ice maker according to the present invention has a close contact structure so that no gap is generated when the fitting groove 330 is inserted into the cold exhaust pipe 400, thereby reducing the conventional gap by about 80% to 95%, thereby reducing the refrigerant By minimizing the leakage of ice, the efficiency of the ice maker can be improved and the ice size can be uniformly produced without variation.
