The present invention relates to a cold air outflow prevention device of the refrigerator, and particularly to prevent the cold air in the refrigerating chamber leaked out when the door is opened to reduce the refrigeration efficiency.

In the conventional refrigerator, as shown in FIG. 1, a freezing compartment 2 is formed at an upper portion of the main body 1, and a refrigerating compartment 3 and a vegetable compartment 4 are formed at a lower portion thereof.

In addition, a freezing compartment door 6 is formed at the front side of the freezing compartment 2, and a door 6 is formed at the front side of the refrigerating compartment 3 and the vegetable compartment 4, and various foods can be placed in the door 6. A storage 7 was formed.

In the refrigerator configured as described above, the beverage and water were often stored in the storage unit 7 formed in the door 6, and the food or large food was stored in the shelf 8 formed in the refrigerating chamber 3.

When the door 6 is opened to take out the food in the state where the food is stored in this way, the cold air of the refrigerating chamber 3 and the vegetable chamber 4 flows out.

Therefore, when the door 6 is opened, the cold air of the refrigerating compartment 3 and the vegetable compartment 4 flows out, and thus the refrigeration efficiency of the food being stored in the refrigerating compartment 3 and the vegetable compartment 4 or the storage unit 7 of the door 6. There was a problem of falling.

In view of the above, the present invention provides an opening / closing door to prevent cold air from leaking out of the refrigerator compartment to the outside when the door of the refrigerator is opened, and is formed to open and close the cold air leakage preventing door selectively. It is an object to provide a means for preventing the cold air in the refrigerating chamber from flowing out when the door is opened.

In the cold air outflow prevention device of the refrigerator of the present invention, the freezing chamber 102 is formed as shown in FIGS. 2 to 4, and the refrigerating chamber 103 and the vegetable chamber 104 are formed at the lower portion thereof.

In addition, a freezing compartment door 105 is formed at the front of the freezing compartment 102, and a door 106 is formed at the front of the refrigerating compartment 103 and the vegetable compartment 104, and various foods are placed in the door 106. The storage unit 107 is formed, and the door 106 is connected to and fixed to the connecting rod 109 arranged and rotated on the hinge shaft 108, the refrigerator compartment when opening the door 106 of the refrigerator The cold air leak prevention door 110 formed to prevent the cold air from leaking out to the outside 103 and the opening and closing means formed to selectively open and close the cold air leak preventing door 110 were provided.

In addition, the cold air leak prevention door 110 is formed to be transparent, and a rubber magnet 111 is provided at the edge portion of the inner surface of the cold air leak preventing door 110 to be attached to the wall surface of the refrigerating chamber 103. .

The opening and closing means may selectively lock the hinge means formed at one side of the cold air leak prevention door 110 and the cold air leak prevention door 110 at the other side of the cold air leak prevention door 110 in which the hinge means is formed. It was provided with a locking means formed to.

The hinge means includes a pivoting hole 112 formed to pivot on the hinge shaft 108 of the door 106, a connection pipe 113 fixedly connected to the pivoting hole 112, and the connection. The other end of the tube 113 was fixed to the cold air leakage prevention door (110).

In addition, the locking means is formed between the shaft 114 formed on the door 106, and the locking interval 115 and the locking interval 115 formed so as to be rotated on the shaft 114 so that both ends can move in the opposite direction. When the bent portion 116 formed at the tip is opened, the hole 117 is formed to be caught by the cold air leak prevention door 110, and when exited, and the tip of the lock section 115 is opened or folded. Selection means for selecting was provided.

In addition, the selection means is bent portion 116 formed in the lock section 115 by pulling one end of the locking feeling 115 to the outer shaft because the power is supplied when the button 118 formed on the door 106 is pressed and is self-rotating When the first electromagnet 119 is formed to be caught by the cold air leakage prevention door 116 and the button 118 formed on the door 106 is not pressed, power is supplied and magnetized so that one end of the lock section 115 is closed. The second electromagnet 12 is formed to be pulled inward so that the bent portion 116 formed in the lock section 115 can escape from the hole 117 formed in the cold air leakage preventing door 110.

In the drawing, reference numeral 121 denotes a cold air discharge hole formed in the wall of the refrigerator, and 122 is a cold air inlet hole formed in the packing rubber of the door 106.

In the refrigerator of the present invention configured as described above, small foods such as beverages are often stored using the storage unit 107 formed in the door 106, and large foods are stored in the refrigerating chamber 103.

Therefore, the door is frequently opened to take out food, such as beverages, which are usually stored in the storage unit 107 of the door 106. At this time, the cold air leakage prevention door 110 prevents the cold air from the refrigerating chamber 103 from leaking.

That is, since the rubber magnet 111 formed at the edge of the inner surface of the cold air leak prevention door 110 is attached to the wall surface of the refrigerating chamber 103, the cold air in the refrigerating chamber 103 can be prevented from leaking.

At this time, since the power is supplied to the second electromagnet, the second electromagnet 120 is magnetized, so that one end of the lock section 115 is absent and the bent portion 117 formed at the other end is cold. The width is narrower than the hole 117 formed in the spill prevention door 110. Therefore, even if the door 106 is opened, the cold air leakage prevention door 110 is not opened.

When the food stored in the refrigerating chamber 103 is taken out, when the button 118 formed on the handle of the door 105 is pressed, power is supplied to the first electromagnet 119 so that the first electromagnet 119 is provided. The magnetization pulls one end of the lock section 115.

Therefore, since the lock section 115 is rotated about the shaft 1 14, the bent portion 116 formed at the tip of the lock section 15 is opened so that the bent portion 116 is cold air leak prevention door 110. Is caught.

As such, when the door 106 is opened in the state where the bent portion 116 is caught by the cold air leakage prevention door 110, the cold air leakage prevention door 110 hanging on the bent portion 116 is opened.

At this time, since the connecting rod 113, one end of which is fixed to the inner end of the cold air leakage prevention door 110, is connected to the pivoting hole 112 which is formed on the hinge shaft 108 and is rotated, the cold air leakage preventing door 110 is It opens while rotating about the hinge axis 108.

Therefore, since the cold air leakage prevention door 110 blocks the storage unit 107 formed in the door 106, it is possible to prevent the cold air in the storage unit 107 from leaking out.

This invention is an invention that can increase the refrigeration efficiency by preventing the cold air of the refrigerating compartment to be leaked when the door of the refrigerator is frequently opened.
