The first control member 181 and the second control member 182 are engaged with each other when the door 20 is closed so that the power of the motor 160 is transmitted, and when the door 20 is opened, the door 20 is separated from each other. ) Can be opened smoothly.

      5 is a perspective view showing a first control member and a second control member in the power transmission means in the refrigerator according to the present invention. FIG. 5A illustrates a state in which the first control member and the second control member are engaged with each other, and FIG. 5B illustrates a state in which the first control member and the second control member are spaced apart from each other.

      As shown in FIGS. 3 to 5, the first intermittent member 181 includes a disk-shaped first coupling part 181a and a first coupling part 181a that are coupled to the rotation shaft 160a of the motor 160. Has two first catching portions 181b extending from the motor 160 to the opposite side of the motor 160. In addition, the second locking member 182 is coupled to the connecting shaft 183, the second coupling portion 182a having a diameter similar to the first coupling portion 181a, and the connecting shaft (from the second coupling portion 182a) 183 has two second catching portions 182b extending oppositely.

      A first inserting portion 181c is provided between the first catching portions 181b in the circumferential direction of the first coupling portion 181a so that the second catching portion 182b can be inserted, and similarly, A second inserting portion 182c is provided between the two catching portions 182b so that the first catching portion 181b can be inserted. Here, the first insertion portion 181c and the second insertion portion 182c may have their circumferential lengths D1 and D2 such that the second locking portion 182b and the first locking portion 181b can be smoothly inserted or removed. It is formed so as to be larger than the circumferential lengths d2 and d1 of the 2 catching part 182b and the 1st catching part 181b.

      Accordingly, the first interlocking member 181 and the second interlocking member 182 are engaged with each other, that is, the second locking portion 182b is inserted into the first insertion portion 181c and the first locking portion is caught in the second insertion portion 182c. When the motor 181 rotates in a state where the portion 181b is inserted, the first locking portion 181b is caught by the second locking portion 182b and the rotational force of the motor 181 is transmitted to the second intermittent member 182. .

Since the configuration of the joint is already widely known, detailed description thereof will be omitted.

      Hereinafter, the operation of the refrigerator related to the gist of the present invention will be described with reference to FIGS. 2 to 4.

      The water supplied to the ice making tray 110 by the water supply means 120 becomes ice by the freezing chamber cold air. The iced ice is separated from the ice tray 110 by the ice-breaking means 130 and then stored away from the ice bank 140. When the user operates the lever 21a provided in the dispenser 21 to extract the ice, the motor 160 installed on the side wall 10a of the main body 10 rotates. At this time, the first intermittent member 181 and the first Since the two intermittent members 182 are in engagement with each other, the rotational force of the motor 160 is transmitted through the first intermittent member 181, the second intermittent member 182, the connecting shaft 183, and the shaft joint unit 184. The conveying member 150 is transmitted to the conveying member 150 to rotate. As the transfer member 150 rotates, the ice in the ice bank 140 moves toward the ice discharge port 151 and is discharged to the dispenser 21 through the ice discharge port 151.

      On the other hand, when the user opens the door 20, the door 20 is smoothly opened as the second control member 182 is separated from the first control member 181 as shown in FIG.

      As described above, the present invention can minimize the reduction of the storage space in the storage compartment to secure the installation space of the motor by installing a motor for transporting ice to the main body, and to reduce the motor noise transmitted to the user through the door. There is an effect that can be reduced.
