Description

Door sealing device for refrigerators and refrigerators

The present invention relates to a door-tightening device for a refrigerator and a refrigerator, and in particular, in a first door and a second door that are slidably opened and closed alternately at an upper part of a main body, respectively, in a lower side and a side part of an inner finishing member of the first door. By forming a sealing film that is in close contact with the upper surface of the glass plate of the second door located to block the outflow of cold air, it effectively blocks the cold air flowing out between the gap between the first door and the second door while the door of the refrigerator and the refrigerator is closed. It relates to a door airtight device of the freezer and refrigerator to improve the freezing and refrigeration efficiency.

Figure 4 shows the upper portion of the conventional refrigeration and refrigerator,

Guides 2 are provided on both sides of the opening 1 of the main body 1 with the upper portion open, and the guides 2 are installed so that the first door 3 and the second door 4 slide and open alternately. .

The first door 3 and the second door 4 are provided with glass plates 31 and 41 which are inserted into the guide 2 and slide to move, and both ends of the glass plates 31 and 41 are closed. 32 and 42 are coupled, and handles 33 and 43 are formed to protrude upward from the upper end of the closing members 32 and 42 to allow the user to open and close the door.

The finishing members 32 and 42 are extruded as a resin material and have a function of being in close contact with the opening surface of the main body 1 so that cold air does not flow out.

However, in the related art, when the first door 3 and the second door 4 are closed as shown in FIG. 4, cold air flows out between the gaps between the lower second door 4 and the upper first door 3. There was a problem that the function of the freezer and the refrigerator is reduced.

That is, when the doors (3) and (4) are closed, the first and second doors (3) and (2) should be shut off while the closing members (32, 42) existing on the center face each other. 4) because there is a certain gap between the cold air inside the main body 1 through the gap between the finishing member (32,42) to the outside, thereby reducing the efficiency of the freezer and refrigerator, especially in the summer As the outflow of cold air intensified, there was a problem that the efficiency of the freezer and refrigerator decreases.

Therefore, the present invention for solving the above problems in the first door and the second door slidingly open and close alternately in the upper portion of the main body, the second door which is located on the bottom and side portions of the inner closing member of the first door, respectively The sealing film closes the upper surface of the glass plate to block the outflow of cold air, and effectively blocks the cold air flowing out between the gap between the first and second doors while the doors of the refrigerator and the refrigerator are closed, thereby effectively freezing and refrigerating efficiency. It is an object of the present invention to provide a door airtight device for a refrigerator and a refrigerator to be improved.

The present invention for achieving the above object,

In the door of the freezer and refrigerator, the guide is installed in the opening of the upper body, the first door and the second door, which are combined with the closing member on both sides of the glass plate, are guided by the guide to slide open and close alternately. ,

The first sealing film is integrally formed on one side of the bottom surface of the closing member of the first door located at the upper part so that the first sealing film is in close contact with the upper surface of the glass plate of the second door located at the lower side when the first door and the second door are closed. To prevent the leakage of cold air, the first sealing film is characterized in that formed integrally with the finishing member by the extrusion operation.

In addition, the second sealing film which is in close contact with the upper surface of the glass plate of the second door located on the side of the closing member is characterized in that the integrally formed.

According to another embodiment of the present invention,

Forming fitting grooves are formed at one side of the bottom surface and at the bottom of the bottom of the finishing member, respectively, and the first sealing film and the second sealing film are fitted into the fitting grooves.

Hereinafter, a preferred embodiment of the present invention with reference to the accompanying drawings, Figures 1 to 3 as follows.

In the description of the present invention, the same components as in the prior art will be denoted by the same reference numerals to avoid redundant description.

According to the drawing, the biggest feature of the present invention is to form the first sealing film 10 to the lower side on the bottom surface of the finishing member 32 formed inside the first door (3).

The first sealing film 10 is preferably formed integrally with the finishing member 32 by an extrusion operation so that the durability is improved.

When the first sealing film 10 is formed below the finishing member 32, the glass plate of the second door 4 in which the first sealing film 10 is positioned below the door when the door is closed as shown in FIG. 2. (41) close to the top surface to block the outflow of cold air.

Meanwhile, a second sealing film 11 is formed at the lower side of the side of the finishing member 32. The second sealing film 11 is also formed integrally with the finishing member 32 by an extrusion operation, thereby improving durability. The length of the second sealing film 11 is slightly longer than that of the first sealing film 10 so as to be in close contact with the upper surface of the glass plate 41 of the second door 4 located below.

As the second sealing film 11 is formed, the blocking rate of the cold air flowing out between the gap between the first door 3 and the second door 4 may be expected to be further improved.

Referring to the operation and effects of the present invention configured as described above are as follows.

When the first door 3 and the second door 4 are closed as shown in FIG. 2, the closing member 32 formed inside the first door 3 and the closing member formed inside the second door 4 are closed. 42 is stacked, but in the related art, cold air flows out between the gaps of the finishing members 32 and 42 to reduce the efficiency of the refrigerator and the freezer.

However, in the present invention, the first sealing film 10 and the second sealing film 11 formed on the bottom and side surfaces of the finishing member 32 are respectively upper surfaces of the glass plate 41 of the second door 4 below. It will be able to expect the effect of improving the efficiency of the freezer and refrigerator because it will completely block the induction of cold air while being in close contact with.

On the other hand, Figure 3 shows another embodiment of the present invention,

A fitting groove 12 is formed in each of the bottom and one side and the bottom surface of the closing member 32, and the first sealing film 15 and the second sealing film 16 are fitted into the fitting groove 12.

As the first sealing film 15 and the second sealing film 16 are fitted into the fitting groove 12 of the finishing member 32 as described above, the first and second sealing films 15 and 16 are disposed on the lower second side. While contacting the upper surface of the glass plate 41 of the door 4 to block the outflow of cold air.

As described above, according to the present invention, in the first door and the second door which are slidably opened and closed alternately from the upper part of the main body, the upper surface of the glass plate of the second door is located at the bottom and side surfaces of the inner finishing member of the first door, respectively. By forming a sealing film to close the cold air to prevent the outflow of the cold air, the cold air flowing out between the gap between the first door and the second door in the state of closing the door of the refrigerator and the refrigerator is effectively blocked to improve the freezing and refrigeration efficiency. The effect of providing a door airtight device for refrigeration and refrigerator can be expected.
