Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a cover which is mounted on a cold air passage having a concave cross section at the back of a refrigerator compartment and has a cool air outlet, and which communicates with the rear surface of the cool air hole without displacing the cool air hole. The present invention relates to a structure provided with a cold air path cover made of a heat insulating material stuck so as not to impair the appearance and prevent dew condensation from occurring at the periphery of the cool air outlet.

[0002]

2. Description of the Related Art As shown in FIG. 1, for example, a conventional refrigerator has an insulating box 1 comprising an outer box 1a and an inner box 1b, and a heat insulating material 1c filled between the outer box 1a and the inner box 1b. A cold air path 7 having a concave cross section with an open front surface is provided on the rear surface 3a of the refrigerator compartment 3 formed by a partition wall 2 partitioning the inside vertically.
And a cover 6 provided with a plurality of cold air outlets 4 for blowing cold air a into the refrigerator compartment 3 at the front open portion of the cold air passage 7.
And a heat-insulating material 6 ′, which is attached to the back surface of the cover 6 and is provided with a heat-insulating material 6 ′ in which the cold-air outlet 4 communicates with the cold-air hole 5 having a small diameter.

[0003]

However, as shown in FIGS. 3A and 3B, the position of the cold air hole 5 is shifted from the position of the cold air outlet 4 as shown in FIGS. There is a problem that the cold air holes 5 become visible and invisible, thereby deteriorating the appearance, and that dew condensation occurs on the peripheral edge b of the cold air outlet 4 corresponding to the location where the cold air holes 5 are hidden. I was

[0004] Therefore, in the present invention, in view of the above problems, it is mounted in a cold air passage having a concave cross section on the back of the refrigerator compartment,
A cover having a cool air outlet and a cool air path cover made of a heat insulating material adhered to the back surface so that the cool air holes communicate with each other without being displaced, impairing the appearance, and providing a peripheral portion of the cool air outlet. An object of the present invention is to provide a refrigerator in which dew condensation does not occur.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a front surface open to the back of a refrigerator compartment formed by partition walls vertically dividing the inside of a heat insulating box. A cold air passage having a concave cross section is provided, and a cover provided with a plurality of cold air outlets for blowing cold air into the refrigerator compartment at the front open portion of the cold air passage; In a refrigerator equipped with a cold air path cover made of a heat insulating material communicating with small diameter cold air holes, a concave portion is formed on the front surface of the heat insulating material attached to the cover, while the concave portion is formed on the rear surface of the cover. Is provided.

Further, the concave and convex portions are provided near the cool air outlet.

[0007] Further, the concave portion and the convex portion are provided at symmetrical positions.

[0008] Further, the cross-sectional shape of the concave portion and the convex portion is substantially rectangular.

[0009]

FIG. 1 is a block diagram showing an embodiment of the present invention.
A description will be given based on FIG. FIG. 1A shows the refrigerating compartment and the other appearance of the refrigerator, and FIG. 1B shows the sectional shape of the refrigerating compartment. In the figure, reference numeral 1 denotes an insulating box, which is an outer box 1a made of a steel plate, an inner box 1b made of a synthetic resin, and an insulating material 1c filled between the outer box 1a and the inner box 1b. In the same manner as the above-described basic configuration in the related art, a cold air having a concave cross section with a front opening is provided on a back surface 3a of a refrigerating room 3 formed by a partition wall 2 partitioning the inside of the heat insulating box 1 up and down. A cover 6 having a plurality of cool air outlets 4 for blowing cool air a into the refrigerator compartment 3 at the front open portion of the cool air passage 7; The outlet 4 has a configuration in which a cold air path cover made of a heat insulating material 6 'communicating with a cold air hole 5 having a small allowable diameter is mounted.

According to the present invention, the appearance of the cold air passage cover 4 is impaired due to the misalignment between the cover 6 constituting the cold air path cover and the heat insulating material 6 'attached to the back of the cover 6. As shown in FIGS. 2A and 2B, a concave portion 6a is formed on the front surface of the heat insulating material 6 ', while the concave portion 6a is formed on the The configuration is such that a convex portion 6b corresponding to the concave portion 6a is provided.

The concave portion 6a and the convex portion 6b are located near the lower portions of the cool air holes 5 and the cool air outlet 4, respectively.
In addition, as shown in FIG.
Further, by making the cross-sectional shape (shape as viewed from the front) of the concave portion 6a and the convex portion 6b substantially rectangular, the displacement between the cool air hole 5 and the cool air outlet 4 is further reduced.

[0012]

In the case of a cold air path cover comprising a cover as described above and a heat insulating material adhered to the back surface thereof, the position of the cold air outlet provided in the cover and the position of the cold air hole provided in the heat insulating material. Easy alignment, impaired appearance,
There is no dew condensation on the periphery of the cool air outlet,
The supply of cold air to the refrigerator compartment is stabilized, and a high-quality refrigerator can be obtained.
