Ice maker 10 according to an embodiment of the present invention is a drive cam (D2) for driving the ice shaft (S) of the ice maker as shown in Figures 2 to 7, and provides a one-way rotational force to the drive cam ( A driving actuator D1 for driving D2) and a one-way clutch portion OC provided between the driving cam D2 and the driving actuator D1.

Power is transmitted from the drive actuator D1 to the drive cam D2 by the one-way clutch part OC, but power transmission is blocked in the opposite direction. Therefore, when a typical ice maker is driven, rotational force can be transferred from the driving actuator D1 to the driving cam D2, and when the user directly drives the driving cam D2 for testing, the rotational force is transmitted to the driving actuator D1. Therefore, damage to the driving actuator D1 can be prevented.

The one-way clutch portion OC may include a driving gear 300 interlocked with the driving cam D2, one or more idle gears 200 coupled to an inner tooth portion 330 of the driving gear 300, and the inner gear OC. The cap 100 is inserted into the tooth 330, interlocked with the driving actuator D1, and intermittently rotates the idle gear 200.

In this case, when the cap 100 rotates in one direction by the driving actuator D1, a portion of the cap 100 contacts the idle gear 200 to stop the rotation of the idle gear 200. Power is transmitted from the drive actuator D1 to the drive cam D2.

In addition, when the driving cam D2 is rotated in the opposite direction by an external force, the idle gear 200 is coupled to the inner tooth 330 to rotate, so that power is generated between the driving actuator D1 and the driving cam D2. To be blocked and will be described later.

The cap 100 has a plate shape and a cap main body 110 interlocked with the driving actuator D1, protrudes from the cap main body 110, and is inserted into the inner tooth 330 of the driving gear 300. It is made of a power interruption unit 130.

The power interruption unit 130 has a cylindrical interruption unit body 131 and a cutout portion 134 in which one side of the interruption unit body 131 is partially cut in the radial direction and the idling gear 200 is disposed. And a wedge portion 132 and an arc portion 133 respectively formed at points where both ends of the cutout portion 134 and the intermittent portion main body 131 meet.

That is, as shown, the intermittent body 131 has a cylindrical shape and is disposed in the inner tooth 330 of the driving gear 300. In the case of the embodiment shown in Figure 5, one side of the intermittent body 131, one side of both sides are radially cut to have an overall bloated shape. The idling gear 200 is seated on the cap body 110 through a space formed by the cutout 134.

The wedge 132 is bent at a specific angle is inserted between the teeth in the idle gear 200 according to the rotation of the cap body 110, the side of the idling gear 200 direction of the arc portion 133 is specified Curvature is formed so as not to contact the idling gear 200 even when the cap body 110 is rotated.

As described above, the wedge 132 is formed at a point where one side end of the cutout 134 meets the intermittent body 131 and is cut at a specific angle. To this end, the intermittent body 131 in contact with the wedge 132 is formed as a flat surface 131-1 as shown in FIG. 5, and the cutout 134 in contact with the wedge 132 is also flat. It may be formed as a surface (134-1). Both flat surfaces 131-1 and 134-1 may be in contact with each other and may be formed as a wedge portion 132 having a specific angle (eg, 90 degrees) and being sharply formed.

In addition, as shown in FIG. 5, a side surface of the arc portion 133 facing the idling gear 200 is formed with a curved surface 134-2 curved with a specific curvature, and the curved surface 134-2 is a cap. Even when the main body 110 is rotated, the main body 110 is formed at a predetermined interval so as not to contact the idling gear 200. This will also be described later.

The wedge 132 is formed on the side close to the idling gear 200 when the power intermittent part 130 is rotated in one direction by the drive actuator (D2). When the power intermittent part 130 rotates in the counterclockwise direction, the power intermittent part 130 is formed on the right side of the drawing of the idling gear 200 so as to be close to the idling gear 200. On the contrary, when the power interrupter 130 is rotated in one direction by the driving actuator D2, the power interrupter 130 is formed on the side away from the idling gear 200 and is formed on the left side of the drawing of the idling gear 200. Reference)

Meanwhile, a seating groove 112 is formed in the cap main body 110 corresponding to the bottom surface of the cutout 134 of the interruption main body 131, and a part of the idling gear 200 is inserted therein. The seating groove 200 is formed in the circumferential direction of the cap body 110 as shown in FIG. The seating groove 112 allows the idling gear 200 to idle.

The rotational force generated by the driving actuator D1 is transmitted to the cap 100. To this end, the insertion part 153 of the plate shape is formed in the intermittent body 131 to be recessed. The locking groove 111 is formed on the opposite side of the cap body 110 of the cap body 110 to be recessed. A through hole 113 is formed at the bottom of the locking groove 111 so that the insertion groove 153 and the locking groove 111 communicate with each other.

The driving actuator D1 includes a driving plate D1-1 that rotates having a plate shape and a protrusion bar D1-2 formed at an end of the driving plate D1-1. At this time, the driving plate (D1-1) is inserted into the insertion groove 153 is engaged, the projection bar (D1-2) is inserted into the through hole 113. That is, when the driving plate D1-1 is rotated by the driving actuator D1, the driving plate D1-1 is caught and the power intermittent 130 is rotated, thereby rotating the entire cap 100. Since the protrusion bar D1-2 is inserted into the through hole 113, more stable rotation of the driving plate D1-1 is possible. The driving actuator D1 may use a well-known electric motor and the like and a detailed description thereof will be omitted.

The drive gear 300 is linked to the drive cam D2. The drive gear 300 receives the rotational force or is blocked by the power interruption unit 130 of the cap 100. The drive gear 300 is composed of a gear body 310, the inner tooth portion 330 and the outer tooth portion 320.

The gear body 310 is a hollow cylindrical shape, the side of the cap direction 100 is open, the opposite side is closed while a portion is formed through the opening 340 is opened. An inner tooth portion 330 having a tooth shape is formed inside the gear body 310. The outer tooth portion 320 having a tooth shape is formed on the outer side of the gear body 310.

4 and 5 in the gear body 310 in the direction of the cap 100, that is, the right side in the drawing is open and the left side is closed on the opposite side. A through part 340 is formed in the closed gear body 310. The driving plate D1-1 of the driving actuator D1 penetrates the through part 340 and is inserted into the insertion groove 153.

An inner tooth portion 330 is formed inside the gear body 310, and an outer tooth portion 320 is formed outside the gear body 310. The idling gear 200 as described above is coupled to the inner tooth portion 330, and the cap body 110 and the power interruption unit 130 of the cap 100 are inserted into the inner tooth portion 330.

The groove 350 is formed in the circumferential direction around the through part 340 of the inner surface of the gear body 310. The idling gear 200 is seated in the recess 350.

The idling gear 200 includes a bar-shaped shaft 210 and a toothed portion 220 formed around the shaft 210 and coupled to the inner tooth 330 of the drive gear 300. At this time, one side of the shaft 210 is inserted into the recess 350 of the drive gear 300, the other side of the shaft 210 is inserted into the seating groove 112 of the cap 100.

Hereinafter, a driving method using the ice maker of the present invention will be described with reference to FIGS. 8 and 9. In this case, the ice maker includes a drive cam D2 for driving the ice shaft S of the ice maker, a drive actuator D1 for driving the drive cam D2 by providing a one-way rotational force, and the drive. It consists of a one-way clutch portion (OC) provided between the cam (D2) and the drive actuator (D1), the one-way clutch portion (OC) is a drive gear 300 which is linked to the drive cam (D2), and the drive One or more idle gears 200 coupled to the inner tooth portion 330 of the gear 300, and inserted into the inner tooth portion 330, interlocked with the driving actuator D1, and rotate the idle gear 200. When the cap 100 is rotated in one direction by the driving actuator (D1), a portion of the cap 100 is in contact with the idle gear 200 to the idle gear 200. The rotation of the 200 is stopped and the drive actuator D1 and the drive cam D2 are stopped. The power is transmitted between the) and when the driving cam D2 is rotated in the opposite direction by an external force, the idle gear 200 is coupled to the inner tooth 330 and rotated so that the driving actuator D1 and the driving cam are rotated. Power is cut off between (D2) (see FIGS. 2 to 7).

The driving actuator D1 provides a one-way rotational force, and the one-way rotational force is a counterclockwise rotational force for description.

When the ice maker operates normally, the driving actuator D1 rotates the cap 100 in one direction, that is, counterclockwise. This is because the driving actuator D1 and the cap 100 are interlocked with each other as described above.

The wedge 132 of the cap 100 is inserted into the teeth of the idling gear 200 by the counterclockwise rotation of the cap 100 so that the rotation of the idling gear 200 is stopped.

That is, the idling gear 200 is coupled to the inner tooth portion 330 of the driving gear 300. When the cap 100 rotates counterclockwise, the wedge portion 132 is connected to the idling gear 200. Is inserted. The idling gear 200 is prohibited from rotating by the insertion of the wedge 132. At this time, since the wedge 132 continues to press the idling gear 200 in the counterclockwise direction, the idling gear 200 is idle in the counterclockwise direction. Since the driving gear 300 is coupled to the idling gear 200, the driving gear 300 rotates in the counterclockwise direction by the counterclockwise revolution of the idling gear 200. By the counterclockwise rotation of the drive gear 300, the drive cam D2 rotates clockwise to rotate and rotate the shaft SH (see FIG. 1).

When testing the ice maker, the external force, that is, the driving cam D2 is forcibly rotated by the user in the opposite direction (clockwise). As a result, the drive gear 300 rotates in one direction, that is, counterclockwise. When the driving gear 300 rotates in the counterclockwise direction, the idling gear 200 coupled to the inner tooth portion 320 of the driving gear 300 revolves away from the wedge portion 132 while revolving in the counterclockwise direction. Rotation of the gear 200 becomes possible. Of course, the idling gear 200 is inserted into the seating groove 112 so that the idling gear 200 can rotate a predetermined distance in the counterclockwise direction of the seating groove 112. When the idling gear 200 revolves counterclockwise in the seating groove 112 and contacts the end of the seating groove 112, the idling gear 200 rotates in place.

That is, the idling gear 200 is rotated by the rotation of the driving gear 300 and the idling gear 200 is separated from the driving intermittent part 130. Therefore, the rotational force transmitted from the driving gear 300 is transmitted only to the idling gear 200 and is not transmitted to the driving interruption unit 130. As a result, since the rotational force is not transmitted to the driving interrupter 130, the rotational force is not transmitted to the driving actuator D1, thereby preventing damage to the driving actuator D1.

As described above, the rotational force generated by the driving actuator D1 during the normal driving of the ice maker is transmitted to the driving cam D2 via the cap 100, the idling gear 200, and the driving gear 300.

If the user forcibly drives the driving cam D2 for the ice maker test, the rotational force is transmitted only to the driving gear 300 and the idling gear 200 and not to the cap 100, so that the rotational force is also applied to the driving actuator D1. Since it is not transmitted, damage to the driving actuator D1 can be prevented.

As illustrated in FIG. 10, the tray TR of the ice maker is disposed to be inclined downward toward the water flow direction, that is, the side where the driving actuator is installed from the side of the water supply part WS. This is because the water supplied to the tray TR to produce ice is introduced into the water supply (WS) flows to the opposite direction. In the case of the embodiment shown in FIG. 10, since the water supply part WS is disposed on the right side of the drawing, water for ice production is introduced from the right side of the drawing and flows to the left side. In order to allow the water to flow more easily, the tray TR is disposed to be inclined downward in a direction in which the driving actuator is installed in the tray TR, that is, in a left direction in the drawing.

To this end, the length of the support bracket IB provided in the tray TR may be adjusted. The support bracket IB includes a first support bracket IB and a second support bracket IB2 as shown in FIGS. 10 and 11. The first support bracket IB1 may be provided at the water supply part WS, and the second support bracket IB2 may be disposed away from the water supply part WS.

The height L2 of the second support bracket IB2, that is, the upper end of the tray TR to the upper end of the second support bracket IB2 is formed higher than the height L1 of the first support bracket IB1. do. At this time, when the heights of the upper ends of the first support bracket IB1 and the second support bracket IB2 are the same and fixed inside the refrigerator, the tray TR is naturally inclined downward at a specific angle θ1 along the water flow direction. Can be.

In addition, as shown in FIG. 12, the tray TR of the ice maker may be disposed to be inclined downward from the inner side of the refrigerator to the opposite side. That is, in FIG. 12, the tray TR may be inclined downward at a specific angle from the inner side (right side in the drawing) installed on the refrigerator to the opposite side (left side in the drawing) to smooth the ice.

To this end, the tray TR may be disposed to be inclined by making the angle θ2 formed in the horizontal direction smaller than 90 degrees.
