The present invention relates to a refrigerator sub-door opening and closing device for opening and closing the home bar (HOME-BAR) provided inside the refrigerating chamber door, in particular to handle the built-in container by opening the sub-door to only a certain angle The present invention relates to a sub-door opening and closing device for a refrigerator in which cold air flow is reduced to a minimum and at the same time.

Generally, a refrigerator includes a freezing system and partitions a main body having an open front side into a freezer compartment and a refrigerating compartment, and installs a freezer compartment door and a refrigerating compartment door on the front side of the main body, respectively. The freezing chamber is maintained at -20 ℃ to -14 ℃ to store the frozen food, the refrigerator compartment is maintained at 3 ℃ to 10 ℃ to store the refrigerated food.

Recently, in order to meet various demands of consumers, refrigerators having separate storage spaces in addition to the freezer compartment and the refrigerating compartment have been disclosed and marketed.

In addition, as shown in FIG. 1, a home-bar is provided in the refrigerator compartment door 1 so that a favorite food such as alcoholic beverages or soft drinks that are frequently used can be easily taken out without opening the refrigerator compartment door 1. ) And a refrigerator equipped with a sub-door 20 for opening and closing the groove-bar 10 on the outer wall of the refrigerating chamber door 1 is disclosed and commercially available.

2 shows an open state of the conventional sub-door 20 shown in FIG. As shown in the figure, the home-bar 10 is formed by forming a space for storing a favorite food such as wine or juice inside the refrigerating chamber door 1.

The rear of the groove-bar 10 is open so that the inner space of the groove-bar 10 is in contact with the cold air circulating in the refrigerating chamber, and also the front of the groove-bar 10, that is, the refrigerating chamber door 1 The outer wall of the sub-door 20 for taking out the food stored in the groove-bar 10 is installed.

As described above, the convenience of the user is improved by allocating a separate space and the sub-door 20 to take out or put frequently used favorite foods without opening the refrigerator door 1. Furthermore, when removing or putting the desired foods out of the home-bar 10, a large amount of cold in the refrigerating chamber can be obtained by using a small sub-door 20 instead of opening a large refrigerator door 1. To prevent leakage.

However, the conventional groove-bar 10 has a hinge member 30 provided on both side walls of the sub-door 20 to open and close the sub-door 20 from the front of the groove-bar 10. It is configured to open up to °, which is inconvenient to use, and there is a disadvantage that can not ignore the leakage of cold air. That is, as shown in FIG. 2, the hinge member 30 includes a first link 31 rotatably fixed to a side of the sub-door 20, one end of which is connected to the first link 31. It is foldably coupled and the other end is composed of a second link 32 rotatably fixed to the side of the groove-bar 10 to open and close the sub-door 20. Accordingly, when the handle 35 (see FIG. 1) formed on the upper portion of the sub-door 20 is pulled downward, the first link 31 and the second link 32 unfold and the sub-door 20 is opened. Since it opens up to 90 °, the operation becomes relatively large, making it inconvenient to use, and in particular, the original purpose of preventing excessive leakage of cold air is halved.

The present invention has been made in view of the above-mentioned, and the refrigerator which not only facilitates the use but also restricts the outflow of cold air by opening the sub-door for the home-bar installed inside the refrigerator compartment door only to a predetermined angle. It is an object to provide a sub-door opening and closing device for the same.

The present invention for realizing the above object is a sub-door for opening and closing the groove-bar installed on the inside of the refrigerating chamber door for storing the favorite food such as wine or juice, and rotatably move the sub-door in the vertical direction And hinge members installed at both lower ends of the sub-doors to be coupled to the groove-bars, and rotation limiting means for rotating the sub-doors rotated up and down by the hinge members only to a predetermined angle. do.

Hereinafter, a detailed embodiment of a sub-door opening and closing device for a refrigerator according to the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 3, the sub-door opening and closing device of the present invention has a groove-bar 50 installed inside the refrigerating chamber door 1 and a groove for storing favorite foods frequently used such as alcoholic beverages or beverages. It consists of a pair of stoppers 81 and a locking member 82 which are respectively installed on the sub-doors 60 installed on the outer wall of the refrigerating chamber door 1 to store or take out the desired food on the bar 50.

Hinge members 70 formed to protrude a predetermined length are disposed at both lower ends of the sub-doors 60, and hinge grooves for accommodating the hinge members 70 are provided at both lower ends of the groove-bars 50, respectively. 51 is disposed. In addition, a handle 65 is provided at the outer upper end of the sub-door 60.

The pair of stoppers 81 is formed to protrude from a higher position than the hinge groove 51 formed on both sides of the groove-bar 50, and the locking member 82 is formed in a 'c' shape so that both ends thereof are formed. Each of the sub-doors 60 is slidably fixed to both sides thereof, and both sides thereof extend horizontally so as to span the stopper 81.

On both sides of the locking member 82, a pair of hooks 83 are formed which are located slightly further inward than the stopper 81 in the state in which the sub-door 60 is closed.

4 shows the sub-door 60 closed. As shown therein, in the state in which the sub-door 60 is closed, the locking member 82 is mounted on a pair of stoppers 81 formed on both side walls of the groove-bar 50, and the hook 83 is It is located further inside the stopper 81. The container A such as juice or wine is inserted and stored in the locking member 82.

Looking at the operation of the present invention configured as described above, first pull the handle 65 of the sub-door 60 to remove the container (A) stored in the groove-bar 50, the hinge member 70 Rotates in the hinge hole 51 to open the sub-door 60. Along with this, the hook member 82 is horizontally moved forward while being mounted on the stopper 81, so that the hook 83 is caught by the stopper 810, as shown in FIG. It is preferable that the stopper 81 and the hook 83 be positioned so that the opening angle of the sub-door 60 is between 45 ° and 50 °.

The sub-door opening and closing device for a refrigerator of the present invention is constructed and operated as described above, so that the container stored in the home-bar is moved forward together with the sub-door by the locking member without opening the sub-door completely. Not only is it easy to take out and store, but it also minimizes the release of cold air.
