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 lighting in a refrigerator.

[0002]

2. Description of the Related Art In a refrigerator, for example, as shown in FIG. 3A, a heat insulating partition (also referred to as a refrigerator main body) 1 comprising an outer box 2, an inner box 3, and a heat insulating material 4 is provided at the uppermost part. There is a refrigerator having a refrigerating compartment 6 defined by the compartment 5. The interior light 12 illuminating the inside of the refrigerator compartment 6 is connected to the refrigerator compartment 6 via a socket 13.
It is provided above and below the upper center of the rear surface of the vehicle, and has a flat interior light cover 14A disposed in front of it.

[0003]

However, in the above-mentioned conventional example, since the interior light 12 is located further behind the front cover 11A provided behind the refrigerator compartment 6, a plurality of interior lights are provided. Despite the twelve, it is impossible to illuminate the interior of the chamber, and the shaded areas are particularly difficult to see. Further, in such a refrigerator, the cold air duct 17A at the rear of the refrigerator compartment 6 is formed so as to be divided into right and left avoiding the interior lamp 13 as shown in FIG. There is a possibility that the air flow path area cannot be obtained and the flow of the cool air is deteriorated. Therefore, an object of the present invention is to provide a refrigerator capable of solving the above-mentioned problems.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and has an upper portion of an inner heat-insulating box formed by filling a heat insulating material between an outer case and an inner case. A refrigerated compartment partitioned by a heat insulating partition is provided on the rear side of the refrigerated compartment, and a duct cover is provided with a plurality of cold air outlets provided at predetermined intervals between the left, right, upper and lower sides of the front face, with both upper and lower faces open and back. To form a cool air duct between the inner box and the rear surface of the inner box, and a cool air passage having a plurality of cool air outlets on the ceiling of the inner box and communicating with the cool air duct between the ceiling and the ceiling. A ceiling plate having a plurality of cool air outlets corresponding to the cool air outlets is provided on the front surface of the duct cover, and a mounting plate having a socket fixed to a front upper center of the front cover is provided. The interior light and the interior light cover were attached via And it formed.

[0005] Further, a recess for accommodating and fixing the mounting plate is formed in the center of the front upper portion of the front cover.

Further, the top plate and the front cover are integrally formed.

Further, the duct cover is fixed behind the front cover.

[0008] Further, a concave portion for accommodating the duct cover is provided on an upper rear surface of the inner box.

[0009] Further, a concave portion forming the cold air passage is provided in a ceiling of the inner box.

FIG. 1 is a block diagram showing an embodiment of the present invention.
A description will be given based on FIG. 1 shows the inside of the refrigerator compartment from the front, FIG. 2 (A) shows the interior of the refrigerator compartment from the side, and FIG. 2 (B) shows the BB arrow shown in FIG. 2 (A). It is an enlarged view of the visual part, in the figure,
Reference numeral 1 denotes an insulating box (also referred to as a refrigerator body) including an outer box 2 made of a steel plate, an inner box 3 made of a synthetic resin, a foamed heat insulating material 4 and the like.
The inside thereof is formed by a heat insulating partition 5 and another heat insulating partition at a lower portion (not shown), and a refrigerator compartment 6 at the upper portion, a freezing room 7 at the center, and a vegetable room (not shown) at the lower portion are formed. An ice machine room (not shown) is provided at one upper side of the freezing room 7, and a water supply tank room 8 for the ice machine is provided at one lower side of the refrigeration room 6, while a low temperature (+ 1 ° C. to −−) is provided at the other side. 3
C), and three transparent shelves 10 are arranged in the upper refrigerator compartment 6.

A front cover 11 provided with a plurality of cold air outlets 11a on the left and right is provided in front of the rear side of the refrigerator compartment 6;
In the center of the front upper portion of the front cover 11, there is a recess 13b for accommodating and fixing a socket 13 for the interior light 12 for illuminating the inside of the refrigerator compartment 6 and a mounting plate 15 for mounting the interior light cover 14. Since the depth corresponds to the thickness of the mounting plate 15, the interior lamp 12 is located forward of the front surface of the front cover 11, and almost the entire area of the refrigerator compartment 6 can be illuminated.

A duct cover 16 as shown in FIG. 2B is arranged between the front cover 11 and the inner box 3 behind the front cover 11, and this duct cover 16 is made of foam insulation. A cool air duct 17 is formed between the upper and lower surfaces of the center and the back surface to form a cool air duct 17 between the back surface of the inner box 3 and a plurality of cool air outlets 16 communicating with the cool air duct 17 at predetermined intervals between the left, right, upper, and lower surfaces.
The duct cover 16 is housed in a recessed state 3a formed on the rear side of the inner box 3 in close contact with the front cover 11 on the front side. .

On the other hand, the ceiling of the inner box 3 has a plurality of cool air outlets 18a as shown in FIG. 1 and forms a cool air passage 19 communicating with the cool air duct 17 between the ceiling cover and the ceiling.
18 are covered. In this embodiment, the ceiling cover 18 and the front cover 11 are separate components, but they may be integrally formed.

By the way, the cool air to the refrigerating room 6 is generated by a cooler in a cool air generating room (not shown) provided behind the freezing room 7 and is sent into the cool air duct 17 by a blower for forced air circulation. The air is supplied through a cool air outlet 16 a formed in the duct cover 16 and a cool air outlet 11 a formed in the front cover 11, and via a cool air outlet 11 b provided in the ceiling cover 18.

[0015]

In the refrigerator as described above, since the interior light is located forward of the front cover provided on the front of the duct cover, the cold air flow path of the cool air duct formed behind the duct cover. By increasing the area and improving the flow of cold air toward the refrigerator compartment, cooling efficiency can be improved and energy can be saved, and lighting can be obtained in every corner of the refrigerator without installing multiple interior lamps as in the past. As a result, the cost can be significantly reduced.
