Description

Refrigerator door gasket

The present invention relates to a door gasket of a refrigerator, and in particular, to form two chambers separated from each other and completely sealed to improve the fixing and sealing power of the door gasket installed to maintain the airtightness of the main body of the refrigerator and the refrigerator door. It relates to a door gasket of the refrigerator by filling each chamber with gas of different properties.

2. Description of the Related Art Generally, refrigerators are broadly classified into direct-cooling refrigerators employing a roll bond type cooler and intercooled refrigerators for forced circulation of cold air generated in the cooler into a freezer compartment and a refrigerating compartment by a blower fan.

Among the types of such refrigerators, in particular, the intercooled refrigerators configured to force circulation of cold air easily generate a change in pressure in the refrigerator because air flow is forcibly generated due to the operation of the blower fan. Therefore, cold air leakage and external air are more likely to be introduced than direct-cooling refrigerators in the form of natural convection cooling.

Accordingly, various types of cold air sealing door gaskets are attached to the door edge of the intercooled refrigerator.

That is, as shown in FIG. 1, a freezing compartment F is formed at an upper portion and a refrigerating chamber R is formed at a lower portion of the refrigerator 80 of the refrigerator.

A freezing chamber door 20 and a refrigerating chamber door 70 are installed to be opened and closed at the front of the freezing chamber F and the refrigerating chamber R, respectively, and a door is formed at an inner edge of the freezing chamber door 20 and the refrigerating chamber door 70. The gaskets 30 are installed to maintain airtightness with the main body of the refrigerator.

The door gasket 30 includes a large magnetic body 60 and a magnetic body insertion groove 65, a first chamber 31, a second chamber 32, and a third chamber 33 which buffer a door when the door is closed. The door gasket 30 is composed of a hook portion 35 to secure the fitting to the inner door 22.

The hook portion 35 is fitted inward through the opening 26 of the hook fixing groove 25 formed in the door inner 22 and at the same time both sides of the hook portion 35 of the hook fixing groove 25 The inner side surfaces of the door gasket 30 are fixed to the inner surface of the freezing chamber door 20 without being separated.

When the freezer door 20 is opened and closed, a buffering action occurs by the first chamber 31, the second chamber 32, and the third chamber 33, and at the same time, the main body cabinet 10 by the magnetic force of the magnetic body 60. It is closely adhered to the front side of the cold air to control the entry.

In addition, wing portions 34 are formed on both sides of the hook portion 35 to further prevent cold air leakage in the refrigerator.

However, such a conventional door gasket 30 is a door gasket 30 fixed to a door inner gasket 22 of the freezer door 20 due to frequent opening and closing of the freezing chamber door 20 and the weight of the door gasket 30. When the second chamber 32 and the third chamber 33 are oriented toward the main cabinet 10 of the refrigerator, and the flow of the door gasket 30 continues, the door inner shell 22 and the door gasket 30 are lifted. Occasionally, the sealing force is lowered due to the deterioration of the sealing force.

In particular, cold air in the freezing chamber F leaks to the lower side of the freezing chamber door 20 and dew is formed on the front surface of the cutting section 80 despite the heat radiated from the hot pipe 90 installed inside the cutting section 80. There was a problem that the phenomenon occurs.

The present invention has been made in order to solve the above problems of the prior art, after forming a separate auxiliary fixing means in addition to the hook portion on one side of the door gasket and at the same time two chambers adjacent to the inner and high outer By filling the gas of different properties, the door gasket is secured and the sealing force is improved, thereby preventing the loss of cold air in the refrigerator and providing the door gasket of the refrigerator to prevent dew condensation occurring at the upper part of the front part of the refrigerator. There is a purpose of design.

This object of the present invention, the present invention is a hook portion that is fixed to the hook fixing groove formed on the inside of the door of the freezer compartment, the magnetic body is installed so that the freezer compartment is closely adhered to the main cabinet side, and divided into several compartments inside In the door gasket of the refrigerator consisting of a plurality of chambers for sealing and buffering, the chamber is formed in two, so as to be completely blocked from the outside, and the longitudinal direction of the chamber in the door that is interviewed with the chamber As a result, a fixing groove is formed, and the chamber is provided with an auxiliary fixing means corresponding to the fixing groove, and at the same time, a chamber adjacent to the high inner side of each chamber is filled with gas having a property that phase change does not easily occur, and adjacent to the high outer side. Achieved by filling the chamber with a gas that easily undergoes phase change even at room temperature do.
