Hereinafter, the ice making process of the ice maker according to the present invention configured as described above will be briefly described with reference to FIGS. 4 and 5, side cross-sectional views showing a part of the ice maker in which the ice-making water guide unit according to the present invention is formed are shown, and FIG. 5 Is a cross-sectional perspective view showing a part of an ice maker in which an ice-making water induction part is formed according to the present invention.

As shown in these drawings, the ice maker 100 according to the present invention has a shape that is substantially vertically bent in the direction of the ice-making groove 15 of the ice-making tray 10 at one end of the ice-making tray 10, as described above. Alternatively, the ice-making water guide portion 200 having a curved shape with a predetermined radius of curvature may be formed. In particular, according to the present invention, as shown in FIG. 5, an ice-making water induction part 200 is formed on one side of the ice-making tray 10, and a portion bent in a cross-section in a'a' shape is provided at the other end of the ice-making tray. Assembly can be made easily by inserting (10) in a slit method.

Accordingly, power is input to the refrigerator 1 including the ice maker 100, and an ice-making motor (not shown) is driven to maintain the ice-making tray 10 horizontally. In addition, after quantitatively supplying and completing water to the ice making groove 15 of the ice making tray 10, the process of checking the temperature range and the ice making is completed after a predetermined time elapses.

As described above, the ice-making water induction part 200 may be vertically bent from the end of the ice-making tray 10 or may be formed in a shape curved with a predetermined radius of curvature. Therefore, when the water contained in the ice-making groove 15 of the ice-making tray 10 flows due to an external shock, that is, the opening/closing operation of the door 8 of the refrigerator 1, before ice-making, the water is moved to the outside of the ice-making tray 10. Water can be prevented from splashing or running down (see blue arrow).

Further, according to the present invention, the ice-making water induction part 200 of the ice-making tray 10 may be formed at a lower portion based on the rotation center of the ice-making ejector 25 (see FIG. 6: blue dotted line). Therefore, while effectively preventing the phenomenon that the water in the ice-making tray 10 is separated to the outside, when the ejection pin 26 of the ice-making ejector 25 rotates after the ice-making is completed, mutual friction with the ice-making water guide unit 200 Or interference can be avoided.

In addition, although not disclosed in the drawings presented by the present invention, additionally rotatable steps (not shown) are added to the inside of the ice-making tray 10 at the end of the ice-making water induction part 200 having a bent or curved shape in some cases. It can be formed as Accordingly, it is possible to fundamentally prevent the water in the ice making tray 10 from being separated from the outside.

In the above, an embodiment of an ice maker and a refrigerator including the same according to the present invention has been described in detail with reference to the accompanying drawings. However, the embodiments of the present invention are not necessarily limited by the above-described embodiment, and it is natural that various modifications and implementations in an equivalent range by those of ordinary skill in the art to which the present invention pertains are possible. will be. Therefore, it will be said that the true scope of the present invention is determined by the claims to be described later.
