  The water supply tank 61 is provided with a transparent and vertical container-shaped water supply tank body 61a made of PS (polystyrene resin) and a detachable tank lid 61c so as to close the opening on the upper surface of the water supply tank body 61a. Yes. A packing 65 is attached to the outer periphery of the tank lid 61c, and the opening of the water supply tank body 61a can be tightly closed by the packing 65.

  The water supply tank body 61 a of the water supply tank 61 has a convex portion 61 a-1 that discharges downward to the bottom surface portion on the back side (right side in FIG. 6) of the refrigerator compartment, and the partition plate 97 stores the water supply tank 61. A concave step 97a (see FIG. 7, concave portion) corresponding to the convex portion 61a-1 (see FIG. 6) is provided at the position.

  As shown in FIG. 6, the water supply tank 61 is connected to the bottom surface portion 61 a-3 on the front side of the convex shape portion 61 a-1 by a gentle inclined surface 61 a-2 that forms the convex shape portion 61 a-1. A foot portion 61d is integrally formed on the near side of the bottom surface portion 61a-3, and the foot portion 61d and the convex portion 61a-1 have substantially the same height in the retracted state and the pulled-out state. Are configured to be in a parallel state.

  In front of the recessed step portion 97a of the partition plate 97, a gentle forward rising inclined surface 97c along the inclined surface 61a-2 of the water supply tank 61 is provided, and on the front side of the inclined surface 97c, a gentler forward lowering is provided. The inclined surface 97d is connected to the flat portion 97e of the partition plate 97. The flat portion 97e is configured at the same height as the recessed step portion 97a. A projecting portion 97b is defined as a portion projecting upward with the portion where the front rising slope 97c and the front falling slope 97d intersect as the apex.

  In addition, a water supply pump unit 64 is fixed to the bottom side of the water supply tank 61 (the convex portion 61a-1). The water supply pump unit 64 includes a water supply pump unit 62 and a water supply pipe 63 (silicon rubber) that is a passage for ice-making water discharged from the water supply pump unit 62.

  The water supply pump unit 62 stores an impeller unit 62a to which a disk-shaped magnet is fixed. The motor unit 96 (driving unit) arranged outside is opposed to the impeller unit 62a and rotated by a magnetic attractive force. It is designed to be driven. A suction port 62 b is provided on the front surface (left side in FIG. 6) of the water supply pump unit 62. The water in the water supply tank 61 is sucked from the suction port 62 b and discharged to the water supply pipe 61 b provided in the water supply tank 61.

  The water supply pipe 61b is formed integrally with the water supply tank body 61a, has an upper and lower opening, and is connected to a water supply pipe 63 at the upper part to circulate the water supplied from the water supply pipe 63 to the lower opening. The lower opening of the water supply pipe 61 b is disposed so as to face the upper surface opening of the water receiving portion 92.

  In addition, you may comprise the water supply pipe line 61b by a separate component from the water supply tank main body 61a. When the water supply pipe 61b is integrally formed with the water supply tank main body 61a, the shape of the water supply tank main body 61a is complicated, and the molding die has a complicated structure. However, if the water supply pipe 61b is configured as a separate part from the water tank main body 61a, there is an advantage that the mold for forming the water supply tank main body 61a can be made simpler.

  The motor unit 96 (driving unit) has a rotating shaft (not shown) disposed in the horizontal direction behind the partition plate 97 and faces the impeller unit 62 a of the water supply pump unit 62 of the water supply tank 61. Thus, a rotating part (not shown) is arranged. A magnet plate is fixed to the rotating portion, and the impeller portion 62a of the water supply pump portion 62 is driven to rotate using a magnetic attraction force through the partition plate 97 and the wall surface of the water supply tank 61.

  8 and 9 are diagrams showing the first embodiment, FIG. 8 is an enlarged view of a portion C in FIG. 4, and FIG. 9 is an exploded view of a water receiving member that receives water from the water supply pipe 61b.

  In a state where the water supply tank 61 is installed at a regular position, the lower opening portion of the water supply pipe 61 b of the water supply tank body 61 a is placed on the upper surface of the water receiving portion 92 via the tank packing 91. The tank packing 91 suppresses water leakage from the water supply pipe 61b into the refrigerator compartment.

  The water receiving portion 92 has a funnel shape with an open upper surface, and is connected to a cylindrical discharge pipe 94 formed of aluminum at the lower portion. A pipe packing 93 is attached to the connecting portion between the water receiving portion 92 and the discharge pipe 94, and the water receiving portion 92 and the discharge pipe 94 are closed tightly to prevent water leakage.

  Since the tip of the discharge pipe 94 faces the ice making chamber, the cold air in the ice making chamber flows from the discharge pipe 94 to the water supply tank 61 side. Therefore, although not illustrated, a heater is provided around the partition plate 97 that covers the outer periphery of the discharge pipe 94 to suppress freezing inside the discharge pipe 94.

  Moreover, the pipe packing 93 provided in the connection part of the water receiving part 92 and the discharge pipe 94 suppresses the leak of the cold air of the ice making room flowing from the discharge pipe 94 to the water supply tank 61 side to the refrigerating room.

  There is little possibility that the cold air in the ice making chamber flowing from the discharge pipe 94 to the water supply tank 61 will enter the water supply tank 61. This is because water always accumulates in the vicinity of the water supply pump unit 62 and blocks the cold air in the ice making chamber. Further, a detachable tank lid 61c is attached so as to close the opening on the upper surface of the water tank main body 61a. A packing 65 is attached to the outer periphery of the tank lid 61c. This is because the opening of 61a is tightly closed.

  The water receiving portion 92 is provided with a handle 92a, and is configured to be easily removed from the front side when the water receiving portion 92 is washed, for example.

  Next, the water supply operation will be described. In the automatic ice making operation, when the motor unit 96 is driven, the impeller unit 62a of the water supply pump unit 62 is rotationally driven. Then, the ice making water in the water supply tank 61 is sucked from the suction port 62b of the water supply pump unit 62, flows through the water supply pipe 63, passes through the water supply pipe 61b, and passes from the water receiving unit 92 through the discharge pipe 94. The ice making water is supplied to the ice tray.

  By driving the motor unit 96 for a predetermined time, predetermined ice-making water is supplied to the ice tray. Thereafter, when ice making is detected in the ice making chamber, the ice removing operation is performed by the ice removing mechanism, and the ice in the ice tray is dropped and stored in the ice storage case 20a (see FIG. 2). Thereafter, the above-described water supply operation is performed.

  Next, the case where the water supply apparatus 60 is cleaned (cleaning work) will be described. When cleaning the water supply tank 61, the water supply tank 61 is taken out of the refrigerator compartment by the handle 61e. At this time, in the state shown in FIG. 6, the water supply tank 61 is taken out with the tank packing 91 attached. The cleaning work can be cleaned by removing the tank lid 61c and removing the water supply pump unit 64 (water supply pump portion 62, water supply pipe 63).

  Further, when cleaning the discharge pipe 94, the discharge pipe 94 and the water receiving portion 92 can be simultaneously removed from the refrigerator compartment by holding the handle 92a of the water receiving portion 92 and lifting it upward (the water receiving portion 92). And the discharge pipe 94 are fixed by a pipe packing 93). Thereby, the discharge pipe 94 and the water receiving part 92 can be easily cleaned.

  At the time of mounting, the handle 92a of the water receiving portion 92 is held and inserted by dropping into a predetermined position (the discharge pipe 94 insertion portion of the partition plate 97), and the predetermined position (through hole 80a) of the first heat insulating partition wall 80a. -5).

  FIG. 10 is a diagram showing the first embodiment. When the water supply tank 61 is installed, the vicinity of the water supply tank 61 showing a state immediately before the convex portion 61a-1 of the water supply tank 61 falls into the concave step portion 97a of the partition plate 97. FIG.
