DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooler for use in a refrigerator of a forced air circulation system.

[0002]

2. Description of the Related Art In recent years, refrigerator coolers have been often installed in the vertical direction on the inner surface of the refrigerator in order to improve the convenience of use in the refrigerator.

A conventional cooler is disclosed in, for example,
There is one disclosed in Japanese Patent No. 60875.

Hereinafter, the conventional cooler will be described with reference to FIGS. In the figure, reference numeral 1 denotes a refrigerator main body, and a freezing compartment 3 is provided at an upper portion by a partition wall 2 and a refrigerator compartment 4 is provided at a lower portion.
Is formed. 5 is a freezer compartment door, 6 is a refrigerator compartment door, 7 is a cooler provided on the inner surface of the freezer compartment 3, and has a wide fin 7b and a narrow fin orthogonal to a plurality of meandering refrigerant pipes 7a. 7c are alternately arranged to form a bypass air passage 8. Reference numeral 9 denotes a blower for forcibly circulating the cool air heat exchanged in the cooler 7 to each room. Supplying cool air, the cooler cover 1
0 from the cool air suction port 12
To the air passage, and in the refrigerator compartment 4,
A cool air is supplied into the refrigerating chamber 4 from a cool air discharge duct 13 provided behind the cooler 7, and forms an air passage returning to the cooler 7 from a return duct 14 provided in the partition wall 2. .

[0005] In the refrigerator cooler constructed as described above, when the freezer compartment door 5 and the refrigerator compartment door 6 are opened and closed, moisture enters from the outside into the refrigerator, and the amount of frost formed on the cooler 7 increases. However, the circulating cool air passing through the bypass air passage 8 formed by the wide fins 7b and the narrow fins 7c exchanges heat to keep the freezing room 3 and the refrigerating room 4 at appropriate temperatures.

[0006]

However, the above-mentioned conventional cooler has a wide fin 7b and a narrow fin 7c.
Since these two types of fins are used, manufacturing equipment dedicated to each fin is required, and as a result, there is a problem that the manufacturing cost of the cooler 7 increases. In addition, since the wide fins 7b are used, the depth dimension of the cooler 7 is increased, and as a result, the internal volume of the freezing room 3 is reduced.

An object of the present invention is to provide a cooler having a small depth dimension which can be manufactured at a low manufacturing cost while increasing the internal volume of a freezing compartment.

[0008]

Means for Solving the Problems To achieve the above object, in the refrigerator of the present invention, the refrigerator is provided with a vertical
Installed, cool air sucks in from the lower part and discharges from the upper part
In a refrigerator provided with a heat exchanger, the cooler is a refrigerant pipe.
And a number of plate-shaped fins orthogonal to the refrigerant pipe.
These fins have the same shape and are
From the bottom to the top of the cooler
This forms a bypass air passage through which cool air flows .

[0009]

Since the cooler of the present invention forms the bypass air passage by alternately shifting the fins having the same shape in the front-rear direction, only one type of fin manufacturing equipment is required. As a result, the manufacturing cost of the cooler is low. Can be suppressed.

In addition, since a wide fin unlike the conventional one is not required, the depth dimension of the cooler can be reduced.
The freezer compartment volume is increased.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cooler according to the present invention will be described below with reference to FIGS. The same components as those described as the conventional example are denoted by the same reference numerals, and detailed description will be omitted.

FIG. 1 is a sectional view of a main part of a refrigerator using a cooler of one embodiment, FIG. 2 is a perspective view of the cooler, FIG. 3 is a top view of the cooler, and 15 is a cooler. A plurality of fins 15b having the same shape and the same width are arranged alternately in the front-rear direction so as to be orthogonal to the plurality of rows of meandering refrigerant pipes 15a, thereby forming a bypass air passage 16.

The operation of the refrigerator using the cooler 15 configured as described above will be described below.

[0014] Even when moisture enters from the outside into the refrigerator by opening and closing the freezer compartment door 5 and the refrigerator compartment door 6 and the amount of frost on the cooler 15 increases, the fins 15b of the same width are alternately arranged in the front-rear direction. By shifting, the circulating cool air exchanges heat through the bypass air passage 16 formed between the fins 15b, so that each room can be maintained at an appropriate temperature as in the conventional case.

As described above, since the cooler 15 of this embodiment is constituted only by the fins 15b having the same shape and the same width, the manufacturing cost is reduced, the width is made smaller than that of the conventional fin, and the depth dimension is reduced. Even if the size is reduced, the same performance as the conventional one can be secured.

[0016]

As described above, according to the present invention, a bypass air passage is formed by arranging fins of the same shape alternately in the front-rear direction so as to be orthogonal to a plurality of rows of meanderingly bent refrigerant pipes. Therefore, one type of fin manufacturing equipment is sufficient, and as a result, the manufacturing cost of the cooler can be reduced.

Further, since a wide fin is not required unlike the conventional case, the depth of the cooler can be reduced, and the internal volume of the freezer can be increased.
