As described above, the automatic ice making machine 20 and the ice storage container 30 are disposed inside the freezer compartment 4. As shown in FIG. 2, the ice storage container 30 is disposed inside the storage container 29 and below the ice tray 21 of the automatic ice making machine 20.

  The automatic ice making machine 20 has an attachment frame 24 that is fixed to the refrigerator-freezer 1 and that is open at the bottom. An ice tray 21 that is a container for freezing water is supported rotatably with respect to the mounting frame 24.

  At the time of ice removal, the ice tray 21 is rotated so that the upper and lower sides are substantially reversed by a drive device 22 (see FIG. 1) such as a motor. A part of the ice tray 21 is provided with a stopper portion that contacts the mounting frame 24 and restricts the rotation of the ice tray 21. When the ice tray 21 is reversed by the driving device 22, the ice tray 21 is bent so as to be twisted by the rotational force by the driving device 22 and the reaction force that restricts the rotation by the stopper portion. Thus, the ice frozen in the ice tray 21 is separated from the ice tray 21 and is dropped and stored in the ice storage space 40 in the ice storage container 30 arranged below the ice tray 21. In addition, a buffer member 39 made of, for example, foamed resin is disposed at the bottom of the inner surface of the ice storage container 30 in order to reduce the collision sound between the ice falling from the ice tray 21 and the ice storage container 30.

  FIG. 3 is a perspective view of the ice storage container 30. The ice storage container 30 is a container for storing ice produced in the ice tray 21 and is a substantially rectangular box-shaped body having an upper opening as shown in FIG. The ice storage container 30 is formed from, for example, a synthetic resin.

  On the inner surface of the rear wall 31 of the ice storage container 30, that is, the surface on the ice storage space 40 side, a substantially plate-shaped drop prevention portion 35 that protrudes toward the ice storage space 40 side that is the front is formed. The fall prevention part 35 prevents the ice in the ice storage space 40 from jumping outside when the ice storage container 30 is pulled forward.

  The fall prevention part 35 extends substantially horizontally in the width direction of the refrigerator-freezer 1 so as to reach the other side wall 33 from one side wall 32 of the ice storage container 30. Thereby, the ice pushed up along the rear wall 31 or jumping up can be stopped effectively.

  Further, a second fall prevention portion 36 is formed at the upper end of the rear wall 31 so as to cover the upper end and protrude toward the front ice storage space 40 side and the rear outside. The second fall prevention unit 36 also has a function of preventing the ice from jumping out of the ice storage space 40.

  In addition, a recess 38 that is recessed downward is formed at the upper end of the rear wall 31 so that the ice storage amount detection lever 23 (see FIG. 4) can pass when the ice storage container 30 is pulled forward. The fall prevention part 35 is formed below the recess 38 and is also formed at a position corresponding to the recess 38. Thereby, it can suppress that ice protrudes outside from the recessed part 38 for letting the ice storage amount detection lever 23 pass.

Detecting whether or not a predetermined amount of ice is stored.

  For example, when it is detected by the ice storage amount detection lever 23 that the amount of ice in the ice storage container 30 has not reached a predetermined amount, the ice making tray 21 is rotated by the driving device 22 when the ice making tray 21 manufactures ice. The ice removal operation is executed. Then, after the ice removing operation, the ice tray 21 is returned to the original position by the driving device 22, and then water for ice making is supplied from the water supply tank 26 (see FIG. 1) to the ice tray 21. On the other hand, when it is detected by the ice storage amount detection lever 23 that the amount of ice in the ice storage container 30 has reached a predetermined amount, the ice removing operation is not performed even if ice is manufactured in the ice tray 21.

  As described above, the fall prevention portion 35 is formed on the rear wall 31 of the ice storage container 30. Specifically, the fall prevention part 35 is formed on the inner surface of the rear wall 31 at a position lower than the upper end of the rear wall 31. As a result, when the ice storage container 30 is pulled forward, the fall prevention unit 35 suppresses the movement of the ice pushed up by the ice in front and pushed upward along the rear wall 31 or the ice splashing up and colliding with the rear wall 31. It is possible to prevent the ice from jumping over the rear wall 31 and jumping out of the ice storage container 30.

  In particular, since the fall prevention part 35 is formed at a position lower than the upper end of the rear wall 31, the amount of ice movement is reduced, and the movement of ice that slides vigorously is effectively regulated before the speed increases. It is possible to obtain an excellent effect of preventing the ice from falling.

  In order to effectively suppress the ice and prevent the ice from falling from the ice storage container 30, the height from the bottom of the inner surface of the ice storage container 30 to the fall prevention part 35 is larger than the size of the ice. Desirable dimensions.

  Further, as described above, the second wall portion 36 is formed at the upper end of the rear wall 31 so as to cover the upper end and protrude forward and rearward. Specifically, the second fall prevention part 36 slightly protrudes forward from the upper end of the rear wall 31 and protrudes longer than the front toward the rear. Thereby, it is possible to prevent the ice from climbing over the rear wall 31 and further enhance the effect of preventing the ice from jumping out.

  Further, the fall prevention unit 35 is formed at a position below the lowest point of the rotation locus 21A of the ice tray 21 in a state where the ice storage container 30 is disposed at a predetermined mounting position. Thereby, the protrusion length of the fall prevention part 35 can be ensured large, without the fall prevention part 35 contacting the ice tray 21. FIG.

  Specifically, the front end 35a of the fall prevention unit 35 is located in front of the front end 36a of the second fall prevention unit 36, and the ice tray 21 is in a state where the ice storage container 30 is disposed at a predetermined mounting position. It is located in front of the rear end 21a.

  That is, as shown in FIG. 5 which is a plan view, the fall prevention unit 35 overlaps with the vicinity of the rear end 21a of the ice tray 21 in a plan view in a state where the ice storage container 30 is disposed at a predetermined mounting position. Thereby, the effect of restricting the movement of ice by the fall prevention unit 35 is enhanced, and an excellent effect of preventing the ice from falling can be obtained.

  Further, as shown in FIG. 4, the front end 36 a of the second fall prevention unit 36 is located behind the front end 35 a of the fall prevention unit 35. That is, the fall prevention unit 35 protrudes forward long, and the second fall prevention unit 36 has a forward projection length shorter than the fall prevention unit 35.

  With such a configuration, the rear wall 31 of the ice storage container 30 is brought closer to the rear end 21a of the ice tray 21 while effectively preventing the ice from jumping out by the anti-falling portion 35 protruding long forward. be able to. Therefore, it is possible to secure a large capacity for disposing the cooler 16, the blower 17, the supply air passage 10, and other dampers (not shown) shown in FIG.
