DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a gasket for preventing leakage of cold air, and more specifically, a groove for accommodating a gasket provided between a cabinet and a door is formed in the cabinet, and the cabinet and the door are provided with a groove. The present invention relates to a refrigerator that can effectively block leakage of cold air through a gap between the refrigerators.

2. Description of the Related Art A refrigerator for storing and cooling food is shown in FIG.
As shown in FIG. 2, a cabinet 10 that is partitioned by a partition wall 15 to form a freezer compartment 11 and a refrigerating compartment 12 that are open on one side, and that is installed in the freezer compartment 11 and the refrigerating compartment 12 respectively, It has a freezer compartment door 16a and a refrigerator compartment door 16b for opening and closing the compartment 12. Each door 1
6 is hinged to the cabinet 10.

A gasket 18 is provided on the inner surface of each door 16. The gasket 18 is formed of an elastic material, and is installed over the entire area adjacent to the edge of the inner surface of the door 16. When the door 16 is closed, the gasket 18 contacts the flat surface 14 located at the edge of the opening of the freezer compartment 11 and the refrigerator compartment 12. As a result, the door 16 hermetically closes the freezer compartment 11 and the refrigerating compartment 12, and leakage of cool air from the freezer compartment 11 and the refrigerating compartment 12 is shut off.

However, in the above-described conventional refrigerator, since the gasket 18 contacts the flat surface 14 on the front surface of the cabinet 10, the close contact between the gasket 18 and the cabinet 10 is not firm, so that the leakage of cool air is prevented. There is a problem that can occur. Especially for long-term use,
Repeated opening and closing of the door 16 for a long time may cause a change in the outer shape of the gasket 18, and as a result, a gap is generated between the flat surface 14 and the gasket 18,
The amount of cold air leakage will increase. When the leakage of the cold air occurs, the efficiency of the cooling operation of the refrigerator decreases, and the power consumption of the refrigerator increases.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and the refrigerator door and the cabinet are firmly adhered to each other to minimize the leakage of cool air. It is an object of the present invention to provide a refrigerator that can perform the operation.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator having a cabinet forming a cooling chamber with one side open and a door for opening and closing the opening of the cabinet. A gasket that is installed and that hermetically contacts the cabinet when the door is closed, and that accommodates the gasket in a shape that matches the shape of the gasket at a location where the gasket contacts the cabinet when the door is closed. Is achieved by a refrigerator characterized in that

Here, it is desirable that the gasket is formed over the entire area where the door and the cabinet are in contact with each other. Further, by interposing a magnet in the gasket, the door can be more airtightly adhered to the cabinet by a magnetic force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 3 is a perspective view of the door of the refrigerator according to the present invention in an open state, and FIG. 4 is a plan sectional view of FIG. The refrigerator according to the present invention is the same as the conventional refrigerator shown in FIGS. 1 and 2, and opens and closes a cabinet 30 and a freezer compartment 31 and a refrigerator compartment 32 forming a freezer compartment 31 and a refrigerator compartment 32 partitioned by a partition wall 35. It has a freezer compartment door 36a and a refrigerator compartment door 36b.

The cabinet 30 comprises an outer casing and an inner casing, and the space between the outer casing and the inner casing and the inside of the door 36 are filled with a heat insulating material. Polyurethane, which is light and has excellent heat insulating properties, is mainly used as a heat insulating material. Insulation is cabinet 30
Is filled in such a manner that polyurethane is foamed between the outer casing and the inner casing in an assembled state. The outer casing is coated with a highly durable synthetic resin paint by heat treatment at a high temperature, and the inner casing is made of a synthetic resin such as an impact-resistant styrene resin or an ABS resin.

A gasket 38 is provided on the inner surface of each door 36. The gasket 38 is formed of an elastic material, and is installed over the entire area adjacent to the edge of the inner surface of the door 36. When the door 36 is closed, the gasket 38 contacts the front surface 34 of the cabinet 30 connecting the inner casing and the outer casing at the edges of the freezer compartment 31 and the refrigerator compartment 32.

A groove 40 for accommodating a gasket 38 is formed on a front surface 34 of the cabinet 30. The gasket 38 is accommodated in the groove 40 in a closed state with the door 36 closed, whereby the door 36 is moved to the freezer compartment 31.
And the refrigerator compartment 32 is airtightly closed. Since the gasket 38 is inserted into and joined to the groove 40 in this manner, the closing of the cooling chambers 31 and 32 by the door 36 is made more airtight as compared with a conventional refrigerator in contact with a flat surface, and especially for a long time. Even if the outer shape of the gasket 38 is deformed due to the use of the gasket, the airtight effect is not reduced. Therefore, the leakage of the cool air from the freezer compartment 31 and the refrigerator compartment 32 is effectively shut off, thereby preventing the cooling efficiency of the refrigerator from decreasing and increasing the power consumption.

[0012]

The gasket 38 is provided inside the gasket 38.
The magnet 50 is interposed almost all over the region 8. Due to the magnetic force of the magnet 50, the gasket 38 is more firmly adhered to the bottom and side surfaces of the groove 40 while being housed in the groove 40, whereby the leakage of cool air is more effectively blocked.

Further, according to the present invention, since the space filled with the heat insulating material is reduced by the groove 40 formed in the front surface of the cabinet 30, an additional effect that the consumption of the heat insulating material can be reduced can be obtained. . As described above, the present invention has been described based on the specific embodiments. However, the present invention is not limited thereto, and it is needless to say that changes and improvements can be made within the ordinary knowledge of those skilled in the art. It is.
