Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator in which cold air cooled by a cooler housed in a partition wall is blown into a freezer compartment and a refrigerator compartment through a blower, a casing, a duct, etc. be.

The details of the present invention will be explained below with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a refrigerator main body, and the refrigerator main body 1 includes an inner box 4, a heat insulating material 5, an outer box 6, etc. which form a refrigerator compartment 2, a freezer compartment 3 inside, etc. It is composed of Reference numerals 7 and 8 are doors that close the front openings of the chambers 2 and 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 partition heating material 11, an upper partition heating material 12, an upper partition member 13, etc., and a storage chamber 14 in which a cooler 15 is stored is provided inside. It is formed by a lower partition heat material 11, an upper partition heat material 12, and an inner box 4. 16 is a casing provided on the opposite side of the partition wall 9, and this casing 1
6 has one opening 16a at the top and a cold air outlet 4 of the inner box 4 at the bottom, as shown in FIGS. 2 and 3.
In addition to having a recessed part in the center so that the cold air is divided into sections e and 4f, both ends are formed in a size that spans the freezer compartment and the refrigerator compartment, and a flange for attachment to the inner box 4 is attached to the periphery. 16b. However, this mounting flange 16b is not formed on the side of the refrigerator compartment. In other words, when this casing 16 is attached to the inner box 4 at the portion facing the partition wall, it is fixed at a location on the freezer compartment side. 17 is a blower and 18 is its drive motor. This drive motor 18 is installed outside the refrigerator as shown in the figure. 19 is a cylindrical molded duct provided in the heat insulating material 5, one end of which is inserted into the opening 16a of the casing 16,
The other side is a duct 2 that forms an air outlet 21 to the refrigerator compartment.
It is inserted into 0. 22 is the air outlet 21
This is a damper thermostat for adjusting the amount of cold air installed in the duct 20 forming the duct. 23 is a mouse ring. This mouth ring 23 is attached together with the blower 17 to the inner box 4a opposite to the cooler storage chamber 14 described above. Reference numeral 24 denotes a long hole provided in the inner box 4. When the heat insulating material 5 between the inner box 4 and the outer box 6 is formed by foaming a liquid heat insulating material to form a solid heat insulating material, the middle partition is inserted through the long hole 24. In order to prevent liquid from flowing into the wall 9, it is sealed from the heat insulating material 5 side with tape or the like (not shown).
This elongated hole 24 is provided between the inner box rear surface 4a facing the cooler storage chamber 14 and the inner box rear surface 4b 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. Further, the distance between the partition top 13 having the sealing material 26 and the partition heat top 12 may be 4d. In the former case, for example, even if frost on the back of the inner box of the refrigerator room melts and becomes water, it is blocked by the sealing material 25, so water does not accumulate in the elongated holes 24, so heat conduction is improved. The blocking effect is not lost. The latter has no elongated hole 24 on the contact surface with the upper partition heat material 12, so it has good sealing performance with the back surface of the inner box.

27 is an ice making corner formed in the freezer compartment 3;
28 indicates a container for storing frozen food. Reference numeral 29 denotes an operation unit housing a temperature controller (not shown) for controlling stopping of the refrigeration cycle, etc., and 30 refers to cold air blown out from the cold air outlets 4e and 4f of the inner box 4 to the ice making corner 27 and the freezing container 28. This duct is used to separate the flow into different parts of the body. 31 is a suction port that returns cold air in the freezer compartment into the partition wall 9, and 32 is a suction port that returns cold air after cooling the refrigerator compartment into the partition wall 9.

In the case of a refrigerator having such a configuration, the cooler 1
A part of the cold air cooled in step 5 is blown out into the refrigerator compartment 2 from the opening 16a of the casing 16 via the cylindrical molded duct 19 and the duct 20 by the action of the blower 17, and after cooling the refrigerator compartment 2, it is blown into the interior partition wall 9. The air is returned to the cooler 15 section through a suction port 32 provided therein. On the other hand, the cold air that is divided by the cold air outlets 4e and 4f of the inner box 4 and blown out toward the freezer compartment 3 passes through the duct 30 and is supplied to the ice making corner 27 container 28, etc. in the divided form, and After cooling the container, etc., it is returned to the cooler section 15 through the suction port 31.

In other words, in the 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 cold air going to the ice making corner, cold air going towards the frozen food container 28, etc. It is something that is diverted. The cool air that is thus divided and sent to each location is reliably guided to the desired location by, for example, a cylindrical molded duct.

As explained above, the present invention divides a refrigerator compartment and a freezer compartment by a partition wall in which a cooler storage chamber is formed between a lower partition heating material and an upper partition heating material, and the cooler storage chamber is stored in the storage chamber. In a refrigerator that blows cold air cooled by a cooler to a refrigerator compartment and a freezer compartment through a blower, a casing, a duct, etc., the inner box back face faces the cooler storage compartment, and the inner box rear face faces the refrigerator compartment. Since there are several long holes in between, the cold air cooled by the cooler is applied by the blower to the back of the inner box facing the storage chamber, blocking heat conduction even if it is cooled. As a result, the inner box at the back of the refrigerator compartment is not cooled down. Therefore, dew,
Or there will be no remaining ice. Therefore, there is no need to put a heating element on the back of the inner box, and the effects of power saving and cost reduction are significant.
