DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a front view of the refrigerator 1. FIG. 2 is a vertical sectional side view of the refrigerator 1. FIG. 3 is a diagram for explaining the flow of cool air in the ice making / ice storage room and the freezing room of the refrigerator 1. FIG. 4 is a diagram of the ice storage container of the refrigerator 1. In FIG.
(a) is a view seen from above, and (b) is an ice storage container A of (a).
It is -A 'sectional drawing. FIG. 6 is an exploded perspective view of an ice making / ice storage room, a door, and an ice storage container.

In the refrigerator 1, a refrigerator compartment 2 is formed at the top, a vegetable compartment 3 is formed below the refrigerator compartment, an ice making / ice storage compartment 4 and a switching compartment 5 are further formed below the refrigerator compartment 2, and a refrigerator compartment 2 is formed at the bottom. Freezer compartment 6
Is formed. Further, doors 7 to 11 are provided for each of the chambers.

The door 7 is formed of a rotary heat-insulating door. The doors 8 to 11 are draw-out type heat insulating doors, each of which has a container having an upper surface opening.

An automatic ice maker 40 comprising an ice tray 41 with a rotating mechanism and an ice storage lever 42 is installed above the ice making / ice storage chamber 4. Further, a refrigerator 12 is provided vertically in the back of the vegetable compartment 3. Above the refrigerator cooler 12, a refrigerator blower 13 is provided.

Further, a refrigerator 14 for a freezing room is provided vertically behind the ice making / ice storage room 4 and the switching room 5. Above the freezer compartment cooler 14, a freezer compartment blower 15 is provided.

Further, an ice temperature chamber 16 composed of a partition plate and a lid is provided below the refrigerator compartment 2.

In addition, a cool air outlet (not shown) is formed at the back of each chamber.

On the other hand, a machine room 30 is formed at the lower part of the heat insulating box. Inside the machine room 30, together with the refrigerator 12 and the refrigerator 14, the refrigerant circuit of the refrigeration cycle is provided. , A compressor 31 and a blower (not shown) for a machine room.

When the refrigerator 1 is operated in such a configuration, the cold room 2 and the vegetable room 3 are cooled by the cooler cooler 12, and the cool air is blown out from the cool air blower 13 by the cool air blower 13. It is sent to the rooms and cools each room to an appropriate temperature.

In the ice making / ice storage room 4, the switching room 5 and the freezing room 6, the cool air cooled by the freezer cooler 14 is sent to each room from the outlet of the cool air by the freezer blower 15. Cool each chamber to a suitable temperature.

Here, the automatic ice maker 40 and the flow of cold air will be described. A fixed amount of water is supplied to the ice tray 41 from a water supply tank (not shown) provided at the lower part of the refrigerator compartment 2 through a water supply pipe (not shown). The cold air cooled by the freezer compartment cooler 14 is blown out to the ice tray 41 of the ice making / ice storage room 4 by the freezer compartment blower 15 to make ice.

When the automatic ice making machine 40 detects the completion of ice making, the ice making tray 41 is rotated while being twisted to drop the ice into the ice storage container 17. The ice making is repeated in this manner, and when the ice storage state of the ice storage container 17 is detected by the ice storage detection lever 42 or the water supply tank (not shown) becomes empty, the subsequent ice making is stopped. Thereafter, ice is used and the ice storage container 17 is used.
When the full ice condition is released or when water is supplied to a water supply tank (not shown), ice making is repeated again.

The ice storage container 17 is divided into two storage sections by a partition wall 18. On the back side, an ice tray 4
The ice made in step 1 falls and is stored. On the near side, an ice shovel 19 is stored in an ice shovel storage unit 31.

When the door is closed, a part of the cold air blown into the ice making / ice storage chamber 4 passes through a plurality of cold air vents 20 provided at the bottom of the ice shovel storage section of the ice storage container 17 to form a lower surface of the ice making / ice storage chamber 4. Directly flows out to the cool air outflow hole 21 provided in the air conditioner.

Since the cool air vent 20 is provided at a position above and below the cool air outflow hole 21 provided on the lower surface of the ice making / ice storage chamber 4, the cool air can be more smoothly returned to the freezing chamber 6, thereby saving energy. Play.

Further, since a plurality of the cool air vents 20 are provided in a slit shape, the ice shovel storing portion 31 is provided.
Even if the ice shovel 19 is stored in the chiller, the flow of cool air is not obstructed.

Further, since the cool air smoothly flows from the ice making / ice storage room 4 to the freezing room 6, the amount of cool air blown out to the ice tray 41 is stabilized, so that the ice making ability is improved.

[0029]

As described above, according to the present invention, a smooth flow of cool air is formed by providing a cool air vent at the bottom, which is the lower portion of the ice storage container. Further, since the cool air flows smoothly, the amount of cool air blown out to the ice tray is stabilized, and the ice making ability is improved.
