Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to blow cold air cooled by a cooler housed in a partition wall into a freezer compartment and a refrigerator compartment through a blower, a casing, a storage compartment, etc. It is related to.

The details of the present invention will be explained below with reference to an embodiment shown in the drawings.
is the refrigerator body, this refrigerator body 1 is the refrigerator compartment 2, the freezer compartment 3
It is composed of an inner box 4, a heat insulating sum 5, an outer box 6, etc., which form inside. 7 and 8 are doors that close the front openings of 1 and room arrangement 2.3. 9 is a partition wall that partitions the refrigerator compartment 2 and the freezer compartment 3.

This middle partition wall 9 is composed of a lower partition member 10, a lower part (cutting heat material 11, a top partition cutting heat member 12, a first part partition member 13, etc.), and a cooler 15 is housed inside. A storage chamber 14 is formed by the lower partition heating material II, the northern partition heating material 12, and the inner box 4. 16 is a casing provided at the corner 1 side of the middle partition wall 9;
As shown in FIGS. 2 and 3, this casing 16 has one opening +6a at the top and a cold air outlet 4e of the inner box 4 at the bottom.

In addition to having a concave part in the center so that cold air is divided into 4F, both ends are large enough to span the freezer and refrigerator compartments. It has a mounting flange +6b.However, this mounting flange +6
) 1 is not formed in a location located on the refrigerator compartment side. In other words, when this casing 1G is placed in the inner box 4 at the part opposite to the partition wall, it is fixed at a location on the freezer compartment side. 17 is a blower and 1
This drive motor 18 is installed outside the refrigerator as shown in the figure. 1, 19 is a cylindrical molded duct 1-, which is installed inside the insulation +45, and one end of it is attached to the casing 1G. Insert it into the opening r-l 16 a,
The other side forms the air outlet ITI 2 to the refrigerator compartment.
It is inserted into the -20. 22 is a damper for adjusting the amount of cold air provided in the above-mentioned blowout 21, and 23 is a mouth ring.

This No. 71 nostril 4127 is installed together with the blower 17 in the inner box 4a of the cooler storage chamber 1/l-&,l described above. 2/l is a long hole provided in the inner box 4; When the heat insulating material 5 between the outer boxes 6 is a solid heat insulating material made by foaming a liquid heat insulating material, this elongated hole 24
In order to prevent liquid from flowing into the partition wall 9, the insulation material 5 is sealed with tape or the like (not shown). This elongated hole 24 is provided between the inner box back surface 4a facing the cooler storage chamber 14 and the inner box back surface 4h facing the inside of the refrigerator compartment 2, and its position is as shown in Nos. 4 and 6. It is provided at the contact surface 4C with the upper partition heat material 12 and below the sealing material 25 affixed to the contact portion of the upper partition heat material 12. Moreover, the partition top 1 having a sealing material 26
It may be 4d between 3 and 12 for the partition heat. In the former case, for example, even if frost on the back of the inner box of the refrigerator room melts and flows from the back, it is blocked by the sealing material 25, so water does not accumulate in the elongated hole 2/l, so heat conduction is achieved. The effect of blocking is not lost. The latter is the upper partition heating material 12
Since there is no elongated hole 24 on the contact surface with the inner box, the sealing performance with the back surface of the inner box is good.

Reference numeral 27 indicates an ice-making corner formed in the freezer compartment 3, and reference numeral 28 indicates a container for storing frozen foods. Reference numeral 29 indicates an operation unit housing a temperature controller (not shown) that controls stopping of the refrigeration cycle, etc., and 30 indicates a cold air blowout of the inner box 4 [-, 1/l r, -4f].
The cold air blown out from the ice making corner 27 and freezing container 28
This is a duct for guiding the flow into different parts of the country. 31
1 is a suction port that returns the cold air in the freezer compartment to the partition wall 9, and 32 is a suction port that returns the cold air after cooling the refrigerator compartment to the partition wall 9.

In a refrigerator having a cooling mechanism 11, some of the cold air cooled by the cooler 15 is transferred from the opening +6a of the ring 16 to the cylindrical molded duct 19 and the duct 1 by the action of the blower 17.
20, is blown out into the refrigerator compartment 2, and after cooling the refrigerator compartment 2, is returned to the cooler 15 through the suction port 32 provided in the partition wall 9.

On the other hand, the cold air that is divided by the cold air outlets 4e and 4f of the inside @A and blown out to the freezer compartment 3 side passes through the duct 3C) and is supplied in the divided form to the ice making corner 27 container 28 shade. After cooling the corner and the container 1:11, it is returned to the cooler section 15 through the suction port 31.

In other words, in the notebook casing 16, not only is the cold air going to the refrigerator compartment and the freezer compartment divided, but the cold air going to the freezer compartment is further divided into the cold air going to the ice making corner and the frozen food container 28.
It is divided into cold air, etc. heading towards the area. The cold air that is thus divided and sent to each location is reliably guided to the desired location by, for example, a cylindrical molded shade.

As explained above, the present invention divides a refrigerator compartment and a freezer compartment by a middle partition wall in which a cold 7I11 container storage chamber is formed between a lower partition heat material and a partial partition heat material, and In a refrigerator that blows cold air cooled by a cooler stored in a cooler into a refrigerator compartment and a freezer compartment through a blower, casing, duct, etc.
There are several elongated holes between the back of the inner box facing the room and the back of the inner box facing the storage room. Even if the refrigerator is cooled, the inner box at the back of the refrigerator compartment will not be cooled down because it blocks heat conduction. Therefore, there will be no ice formation or residual ice. Therefore, there is no need to insert a heating element or the like on the back of the inner box, resulting in significant power saving and cost reduction effects.
