A partition for partitioning the ice making room 14 and the freezing room 15 at the lower part where the automatic ice making device 33 and the ice storage box 34 are arranged. The partition is not as thick as the heat insulating material and is relatively thin.

In the refrigerator configured as described above, since the bottle storage room 13 is formed, the door rack 2 inside the door 2 is provided.
6 does not need to be formed large, and can be made less likely to be a factor for narrowing the refrigerator compartment 11. Therefore, the refrigerator can be easily used by appropriately storing the PET bottle 31 and the like.

Further, since the bottle storage chamber 13, the ice making chamber 14, and the freezing chamber 15 are arranged in this order from the left, the following advantages are provided.

When the bottle storage room 13 is arranged on the left, when standing on the front of the refrigerator 1, the bottle storage room 13 is located at a position where it is most easily opened by the left hand. When the door 3 is pulled open with the left hand, the relatively heavy PET bottle 31 or the like can be grasped with the right hand, so that the PET bottle 31 can be easily taken in and out. In particular, even when a tall object is arranged on the front side of the bottle storage chamber 13, the object arranged on the rear side can be taken in and out from above.

The refrigeration compartment 11 above the bottle storage compartment 13 has the highest frequency of opening and closing in the refrigerator 1, and the temperature in the refrigerator tends to be higher than the set temperature. In particular, since the left side is open, the temperature of the left side of the refrigerator compartment 11 tends to rise. Refrigeration room 11 that is susceptible to this temperature rise
A bottle storage room 13 is arranged below the left side of the bottle. However, even if the change in temperature of the PET bottle 31 or the like becomes larger than that in other rooms, the quality is not so deteriorated, so that the influence can be relatively reduced.

Further, by placing the ice making room 14 and the freezing room 15 next to each other, it is not necessary to use a thick heat insulating material as the partition 45 of these rooms, and it is possible to secure a relatively large capacity in the refrigerator. .

Further, since the bottle storage chamber 13 is arranged on the left side, heat flowing from the left side wall of the ice making chamber is relatively large when the ice making chamber is arranged on the left side. Since the bottle 14 is disposed in the center and the bottle storage room 13 is formed on the left side, the flow of heat into the ice making room 14 can be suppressed relatively small.

Although not shown, an openable and closable lid is attached to the bottom surface of the refrigerator compartment 11 on the left side, and when the door 2 is opened, the refrigerator compartment 1 is opened.
It is also possible to open and close the lid that can be opened and closed and then put the PET bottle in the bottle storage room in and out of the storage in the bottle 1.

And a heat insulating material (a wall having heat insulating properties), 54,
55 is a partition that partitions the lower part of the ice making chamber 15 and the freezer compartment 14, which is not as thick as the heat insulating material and is relatively thin.

The refrigerator configured as described above has the following advantages.

When the operation of the compressor is stopped or defrosting, heat may flow into the freezing compartment 14 from both sides.
4 is sandwiched between the bottle storage chamber 13 and the ice making chamber 15, so that the heat flowing into the freezing chamber 14 is small,
4 can keep the temperature change small,
5 can be prevented from deteriorating.

In particular, the freezing compartment 14 of the second embodiment
The top, bottom, left and right are surrounded by each room of the refrigerator,
Since each room of the refrigerator is controlled to a temperature closer to the temperature of the freezing room 11 than the temperature outside the refrigerator, the heat inflow to the freezing room 11 is extremely small from above and below and from the left and right. It is possible to minimize the deterioration of the frozen food 35 and the like as much as possible.

[0031]

As described above, according to the first aspect of the present invention, one of the heat insulating spaces is divided into at least three chambers arranged side by side by a wall having heat insulating properties. At least one of the left and right end chambers is supplied with air adjusted to a temperature effective for cooling of drinking water or the like by the evaporator of the refrigeration cycle, and the temperature of the air is supplied to a room adjacent to the left and right end chambers. Because it is configured to supply low-temperature air, at least one of the left and right end chambers can be used as a room for storing drinking water, etc., and there is no need to form a large door rack inside the door. It can be less likely to be a factor for narrowing the storage room.

According to the second aspect of the present invention, since the three chambers arranged side by side each have a door and are configured to be individually openable and closable, it is possible to use each chamber individually. Can be.

According to the third aspect of the present invention, the heat insulating capacity of a part of the wall surrounding the chamber sandwiched between the left and right end chambers is set based on the design temperature of the adjacent room or the heat insulating space.
When the set temperature is close, the heat insulation capacity of the wall can be reduced, that is, the wall can be made thinner, and a wider storage space in the room can be secured.

According to the fourth aspect of the present invention, the room is at least a freezing room / ice making room, and at least one of the right and left ends adjacent to the freezing room / ice making room is provided with drinking water or the like. Since one of the adjacent rooms of the freezing room / ice making room is effective for cooling drinking water and the like which is closer to the set temperature than room temperature, heat is applied to the freezing room / ice making room. Inflow can be made difficult.

According to the fifth aspect of the present invention,
Since the heat insulation capacity of the wall sandwiched between the ice making room and the room effective for cooling drinking water and the like is made lower than the heat insulation capacity constituting the heat insulating space, the room effective for cooling the drinking water and the like is provided in an adjacent freezing room / ice making room. Therefore, it is not necessary to supply a large amount of cold air to a chamber effective for cooling the drinking water or the like, and the energy required for cooling the chamber effective for this cooling can be reduced.
