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

1 to 5, a rotary water jet nozzle 100 for an ice maker according to the present invention includes an upper nozzle 110 and a lower nozzle 120.

In the upper nozzle 110, a supply water passage through which supply water for ice-making is supplied is formed in a plurality of channels, and is fixed to the upper end of a tubular ice-making unit 200 to which ice-

The water supply part 111 of the upper nozzle 110 has a first supply water passage 111a formed therein in a horizontal direction.

The lower nozzle connecting portion 112 of the upper nozzle 110 extends downward from the center of the water supplying portion 111 and communicates with the first supplying water passage 111a in the downward direction, A second supply water passage 112a to which the first supply water passage 120 is coupled and a second supply water passage 112a to which the second supply water passage 112a is coupled is formed, And an ice-making unit insertion groove 112c which is fitted to an upper end of the ice-making unit 200 along an edge portion of the ice-

The lower nozzle 120 is connected to the upper nozzle 110 in a downward direction and maintains a predetermined gap between the lower nozzle 120 and the upper end wall of the ice making unit 200, The falling supply water is rotated and sprayed toward the upper end wall of the ice making unit 200 so that the supply water flows down from the upper end portion of the ice-making unit 200 through the above-described gap while rotating on the wall.

The manner in which the lower nozzle 120 is coupled with the upper nozzle 110 can be variously applied, such as an interference fit method, a screw coupling method, and the like.

The stem 121 of the lower nozzle 120 is formed with vertical water passages 121a for vertically dropping the supplied water through the upper nozzle 110 at predetermined intervals on the outer surface.

The bottom part 122 of the lower nozzle 120 is extended while forming a predetermined inclined surface at the lower end of the stem part 121 to maintain a predetermined gap between the upper part wall and the upper part wall of the freezing unit 200 And the supply water supplied through the vertical water passage 121a in one-to-one correspondence with the respective vertical water passages 121a on the inclined surface is sprayed toward the upper end wall of the ice making unit 200, Spiral water passages 122a are formed through the gap to allow the water to flow from the upper end portion of the ice-making unit 200 while rotating on the wall.

The angle? Of the inclined surface of the bottom portion 122 is set in a range of greater than 20 ° and less than 90 ° (preferably, greater than 25 ° and less than 90 °), and the water of the helical water passage 122a The injection angle is formed by a first circle (C1) having a longer radius among two concentric circles (C1 ', C1) formed by extending a line formed along both side walls of the spiral water passage (122a) The inclination angle? Of the tangent line L1 of the first circle C1 and the tangent line L2 of the second circle C2 passing through the intersection P of the second circle C2 formed along the outer periphery is 0 Deg.] And smaller than 50 [deg.] (Preferably, larger than 0 [deg.] And smaller than 45 [deg.]).

In the embodiment of the present invention, when the angle α of the inclined surface of the bottom portion 122 is set to 20 ° or less, the flow rate of the water flowing downward along the inclined surface via the vertical water passage 121a There is a disadvantage in that the rotational force of the water sprayed toward the upper part wall of the ice making unit 200 decreases while rotating through the spiral water passage 122a.

Further, as the angle? Of the inclined surface of the bottom part 122 is closer to 90 degrees, the flow rate of the water flowing downward along the inclined surface increases through the vertical water path 121a, When the angle α of the inclined surface of the bottom portion 122 is too large, the upper nozzle 110 and the upper nozzle 110 may be rotated together with the upper nozzle 110, Since the total size of the lower nozzle 120 increases proportionally, it is preferable to set the angle? Of the inclined surface of the bottom 122 to an appropriate angle in a range smaller than 90 degrees.

In the embodiment of the present invention, the angle? Between the tangent line L1 of the first circle C1 and the tangent line L2 of the second circle C2 is smaller than 0, The rotating force of the water sprayed toward the upper end wall of the ice-making unit 200 is increased.

However, when the subtended angle beta is set to 50 degrees or more, the inclination angle beta is set to be smaller than 50 degrees because the rotational force of the water slightly increases as compared with the case where the inclination angle beta is set to be smaller than 50 degrees. It is preferable to set it at an appropriate angle.
