Abstract

An ice supplying apparatus 100 , being provided in a refrigerator 1 , comprises: an ice maker unit 22 , which is configured to supply ice pieces produced therein to an outside of a freezer room door; an ice storage unit 110 , which is configured to store the ice pieces produced by the ice maker unit; an ice discharger unit 112 , which is provided within the ice storage unit to discharge the ice pieces below; and a shrinking portion 111 , which is provided in the ice storage unit and defines an interior space thereof as small as it goes down, through building up a lower surface 113 , among interior surfaces defining that interior space 301 of the ice storage unit 110 , for supporting the ice pieces stored therein from a lower potion thereof, by a surface inclining to a horizontal direction, wherein the ice discharger unit 112 is disposed in a lower portion of the shrinking portion 111.

Claims (33)

1. An ice supplying apparatus, being provided in a refrigerator, comprising:

an ice maker unit, which is configured to supply ice pieces produced therein to an outside of a freezer room door;

an ice storage unit, which is configured to store the ice pieces produced by said ice maker unit;

an ice discharger unit, which is provided within said ice storage unit to discharge the ice pieces below;

a shrinking portion, which is provided in said ice storage unit and defines an interior space thereof as small as it goes down, through building up a lower surface, among interior surfaces defining that interior space of said ice storage unit, for supporting the ice pieces stored therein from a lower portion thereof, by a surface inclining to a horizontal direction, wherein

said ice discharger unit is disposed in a lower portion of said shrinking portion;

a stirrer, which is configured to stir the ice pieces stored within said ice storage unit, wherein said stirrer comprises a stirring body to be disposed within said ice storage unit, and said stirring body is provided to be rotate around a rotation shaft, which is inclined to the horizontal direction; and

an ice crusher unit, which is able to crush the ice pieces discharged from said ice discharger unit, wherein

said ice crusher unit has a switching body, which is configured to switch a passage for the ice pieces between one path for supplying the ice pieces without crushing and other path for supplying the ice pieces with crushing.

2. The ice supplying apparatus, as described in the claim 1 , wherein

on said lower surface is provided a guide portion, for guiding the ice pieces to said ice discharger unit, directing to said ice discharger unit, and

said guide portion is formed to be hollowed in a concave manner.

3. The ice supplying apparatus, as described in the claim 2 , wherein

said lower surface is made up with two (2) pieces of crossing surfaces, crossing with each other,

on one of said two (2) pieces of crossing surfaces is provided said ice discharger unit, and

on the other crossing surface is provided said guide portion.

4. The ice supplying apparatus, as described in the claim 1 , wherein

said ice crusher unit further comprises an ice crusher room, which is configured to crush the ice pieces therein,

said ice crusher unit has an input unit, to which the ice pieces discharged from said ice discharger unit are thrown in, and a discharger unit, which is configured to discharge the ice pieces inputted into an outside, and

said discharger unit is built up with two (2) pieces of discharging portions, which are provided corresponding to said two (2) pieces of paths, wherein

one discharging portion of said two (2) pieces of discharging portions is provided to communicate with said input unit in a vertical direction, and

said switching body is constructed to be switched into a condition of closing said one discharging portion and a condition of not closing it.

5. The ice supplying apparatus, as described in the claim 4 , wherein

said crusher unit for crushing the ice pieces is made up with movable edges rotating within said ice crusher room and fixed edges,

said movable edges rotate while shifting the ice pieces thrown into said ice crusher room, so as to put them between said fixed edges, and thereby crushing them, when said switching body is in the condition of closing said one discharging portion, and

the ice pieces crushed are discharged into the outside from the other discharging portion between said two (2) pieces of discharging portions.

6. The ice supplying apparatus, as described in the claim 1 , wherein said movable edges are provided to be rotatable around the rotation shaft inclining with respect to the horizontal direction.

7. The ice supplying apparatus, as described in the claim 5 , wherein said movable edges have scraping portion to scrape out the ice pieces which can accumulate on a bottom surface of said ice crusher room.

8. The ice supplying apparatus, as described in the claim 1 , wherein said stirrer and said movable edges are provided on a same shaft member.

9. The ice supplying apparatus, as described in the claim 5 , wherein said ice crusher unit is constructed to crush the ice pieces while rotating said movable edges only one direction, and

said movable edges are operated to rotate in a forward direction, again, after rotating in a reversed direction once, when said movable edges come to be unable to rotate.

10. The ice supplying apparatus, as described in the claim 1 , wherein said stirrer unit and said ice crusher unit are disposed to be received within a projection area of said lower surface in the horizontal direction.

11. A refrigerator, comprising the ice supplying apparatus, as described in the claim 1 .
