    3 is a cross-sectional view showing the inside of the ice maker water supply apparatus according to the present invention, and FIG. 4 is a cross-sectional view taken along the line A-A of FIG.
    As shown, the ice maker water supply apparatus according to the present invention includes a pipe pipe 30 connected to an ice maker A for making ice, a casing 40 installed at the rear of the freezer compartment, and an ice making pipe 60 which is a passage of water introduced from the outside. It is composed of
    First, the pipe pipe 30 will be described. The pipe pipe 30 is connected to one side of the ice maker 10 formed on the ice maker A and ice-making ice 10. The inlet 30a of the pipe pipe is a freezing chamber. It is formed through the rear wall.
    The casing 40 is wrapped around the inlet 30a of the pipe pipe, and the casing 40 is fixed to the rear of the freezing chamber by a plurality of screws 43. On the other hand, the rear surface 42 of the casing is formed to form a straight section 42a of a constant height and to form a slope of a predetermined size downward with a constant inclination angle at the end of the straight section 42a. .
    In addition, an adjustment device for controlling the flow of water introduced through the ice making pipe 60 to be described later is installed in the casing 40 to adjust the amount of water supplied into the pipe pipe 30. A flapper 50 may be used as an embodiment of the adjusting device. In the flapper 50, a rotatable shaft 52 is installed at a central portion thereof, and water supplied to the shaft 52 may be in contact with the shaft 52. Horizontal wings (54, 54 ') having a predetermined size area is installed on both sides so that the water through the ice making pipe (60) hits the horizontal wings (54, 54') to rotate the shaft (52). Accordingly, the horizontal blades 54, 54 'are moved at an angle. In addition, the vertical blades 53 connected to the shaft 52 are provided only in one direction downward. The vertical wing 53 is to prevent the water flowing back through the ice making pipe (60).
    In addition, a plurality of center of gravity weights 56 are formed on the lower surfaces of the horizontal wings 54 and 54 ', which are horizontal angles 54 and 54' due to the weight of the weight center weights 56. This is to adjust the movement in. In addition, a sealer 55 is installed at the end of the horizontal blade 54 'toward the rear of the casing 42 of the horizontal blades 54 and 54', which is a water pressure of the water flowing through the ice making pipe 60. Even in this case, as the flapper 50 rotates by a predetermined angle or more, only a predetermined amount of water is introduced into the pipe pipe 30 by the sealer 55 colliding with the inclined surface 42b of the rear of the casing 42. To help.
    Meanwhile, an ice making pipe 60, which is a passage of water introduced from the outside so that water is supplied to the ice maker A, is installed along the rear of the refrigerator, and the clamp 62 is screwed at a predetermined interval of the ice making pipe 60. It is fastened by the ice making pipe 60 to be firmly fixed to the rear of the refrigerator. The outlet 60a of the ice making pipe 60 is formed through one side of the bottom surface of the casing 40 to supply water through the ice making pipe 60 into the casing 40.
    Next, the icemaker water supply device according to the present invention will be described in more detail through the process of supplying water into the ice maker through FIGS. 3 and 4.
    As shown, the ice maker A is installed at one inner rear side of the freezer compartment. 6 In the ice maker A, an ice making unit 10 forming ice is formed at an upper portion thereof, and a storage container unit 20 is installed at the lower portion thereof to store ice formed in the ice making unit 10.
    First, as the user uses the ice using the ice selection button installed on the dispense, the amount of ice stored in the ice storage unit 20 is reduced. Accordingly, the water supply valve is operated so that water flows from the external pipe to the ice making pipe 60 installed along the rear of the refrigerator.
    At this time, before the water flows into the casing 40 through the ice making pipe 60, the flapper 50 installed inside the casing 40 is kept horizontal by the center of gravity, wherein the horizontal wings 54, 54 ' ), The end of the horizontal blade 54 on the pipe pipe 30 side is in contact with the lower end of the pipe pipe inlet 30a, and the horizontal blade 54 'on the casing rear 42 side is the casing rear wall surface 42. The vertical wing 53 is positioned in contact with the bottom surface of the case 40.
    In this case, even if the cold air in the ice maker A flows back through the pipe pipe 30 and flows into the casing 40, the horizontal blades 54 and 54 ′ are prevented from being transferred to the ice making pipe 60 and the ice making pipe is prevented. This prevents water from freezing around 60.
    Next, when water is introduced through the ice making pipe 60, the left horizontal blade 54 is struck upward by the outflow speed of the water through the outlet 60a of the ice making pipe 60, and thus the left horizontal The wing 54 is raised by a predetermined angle (θ as shown in FIG. 4) so that the pipe inlet 30a is opened so that water through the ice making pipe 60 passes through the ice pipe 30. It flows into the ice-making part 10 of A). At this time, the horizontal blade 54 ′ on the right side of the drawing is positioned at the end of the straight section surface 42a of the rear wall surface of the casing 40. At this time, the vertical wing 53 prevents the water through the ice making pipe 60 comes down again.
    On the other hand, when the water supply is completed, the flapper 50 is again leveled by the center of gravity weight 56 to block the pipe pipe 30, whereby the cool air in the ice making unit 10 pipe pipe 30 It is prevented from flowing backward through the ice making pipe 60 side, and also prevents the introduced water from flowing backward.
    In addition, when the water pressure is strong, the sealer formed at the end of the right horizontal wing 54 'is maintained as a large amount of force acts on the horizontal wing 54 on the left side by the pressure of the water through the ice making pipe 60 and maintains many angles. 55 impinges on the inclined surface 42b of the rear of the casing 42 so that it can no longer rotate by the sealing and friction action so that a certain amount or more of water cannot be introduced through the pipe pipe 30.
    As described above, water introduced into the ice making unit 10 through the ice making pipe 60 is iced in the ice making unit 10 and moved into the ice storage unit 20 so that the ice storage unit 20 always has a certain amount. The ice is stored and the process is repeated as the user uses the ice.
    The refrigerator ice maker water supply device according to the present invention described above has the following advantages.
    When water is supplied to the pipe pipe through the ice making pipe, the back flow of water is prevented by the flap, and the cold air is prevented from flowing out to the ice making pipe by the back flow of cold air through the pipe pipe.
    Another effect is that a certain amount of water always flows into the pipe pipe, regardless of the water pressure, to make ice of good quality in the ice making unit.
