The present invention relates to a refrigerator door, and more particularly, to a refrigerator door opening and closing device for opening and closing the refrigerator door in a required direction by allowing the refrigerator door to be coupled to the left and right ends of the refrigerator body.

The general refrigerator has evolved into a refrigerator that can perform both a refrigerating function and a freezing function, instead of performing only a refrigerating function.

Such a refrigerator has a freezer compartment at the top of the refrigerator body, a refrigerator compartment at the bottom of the refrigerator body, and a vegetable compartment for maintaining freshness of vegetables or vegetables on the bottom of the refrigerator, if necessary.

Cold air flowing through the freezer, the refrigerator, and the vegetable compartment discharges cold air generated in the refrigerator from the freezer by using cold air as it is heavier than hot air.

The cold air discharged from the freezer compartment freezes food and other items stored in the freezer compartment, and some of the cold air is discharged into the freezer compartment and introduced into the freezer compartment.

The cold air introduced into the refrigerating compartment is not only part of the total cold air introduced into the freezer compartment, but because the size of the refrigerating compartment is larger than the size of the freezer compartment in most refrigerator structures, it does not freeze the food stored in the refrigerating compartment. Will be maintained.

Convection from the refrigerator compartment keeps the internal temperature of the refrigerator compartment at a constant temperature. Some of the cold air flows into the vegetable compartment installed at the bottom of the refrigerator to maintain the storage temperature of vegetables or vegetables stored in the vegetable compartment.

That is, a general refrigerator is composed of a freezer compartment, a refrigerator compartment, and a vegetable compartment. The cold air introduced into the refrigerator compartment cools the food stored in the freezer compartment by convection in the freezer compartment, and some of the cold air convection in the freezer compartment flows into the refrigerator compartment to maintain a constant temperature in the refrigerator compartment. While maintaining the temperature of the vegetable compartment at a low temperature.

Therefore, the temperature of the freezer compartment, the refrigerating compartment and the vegetable compartment is gradually maintained at a higher temperature to freeze, refrigerate and store the food in storage.

Thus, the bottom of the refrigerator that performs the freezing, freezing and storage functions is provided with a door that opens and closes the freezer compartment, the freezer compartment and the vegetable compartment of the refrigerator. Food is put in or taken out of the freezer compartment, the refrigerating compartment and the vegetable compartment.

Inside the refrigerator door installed at the front of the refrigerator body, various storage spaces are configured to maximize the internal space of the refrigerator, so that bottles or cans are stored / stored using the storage space.

As the technology of refrigerators with doors on the front develops and the demands of consumers increase, the size of the refrigerators increases, and in accordance with the trend of large-sized refrigerators, one door is formed of two doors to separate the freezer and the refrigerator. Will be closed.

That is, such a refrigerator door forms an upper door 101 on the upper side of the refrigerator body 100 and a lower door 102 on the lower side of the refrigerator body 100 as shown in FIG. The upper side of the upper door 101 is coupled to the hinge shaft 108 of the upper hinge 103 to be fixed to the refrigerator body 100, and the lower side of the upper door 101 is the hinge shaft of the central hinge 104. 109 is coupled to the refrigerator body 100 is fixedly installed, the upper side of the lower door 102 is coupled to the hinge shaft 110 of the central hinge 104 is fixed to the refrigerator body 100 while the lower The bottom side of the door 102 is coupled to the hinge shaft 11 of the lower hinge 105 is fixed to the refrigerator body 100.

In addition, the handles 106 and 107 are formed at one side of the upper door 101 and the lower door 102 so that the doors 106 and 107 can be opened and closed easily.

The hinges 103, 104 and 105 connected between the doors 101 and 102 and the refrigerator body 100 may be installed only at one end of the refrigerator so that the upper door 100 and the lower door 102 can be opened and closed. Since the refrigerator doors 101 and 102 can be rotated, it may be necessary to open and close the refrigerator door in a direction opposite to the opening and closing direction formed in the refrigerator due to the refrigerator installation requirements or other circumstances. Since it was fixed to rotate around one end, there was a defect that the door opening and closing direction of the refrigerator could not be changed.

Therefore, the refrigerator door can be opened and closed only in one direction regardless of the installation location or use environment.

Therefore, the present invention is designed to solve the above-mentioned drawbacks, and the hinge door which is coupled between the refrigerator body and the door and becomes a rotation shaft for the door can be installed at the left and right ends of the refrigerator body in any direction. It is an object of the present invention to provide a refrigerator door opening and closing device for opening and closing.

The refrigerator door opening and closing device of the present invention for realizing this purpose is formed in the door of the refrigerator, the upper and the left side fixing groove is exchanged and fixed, the hinge shaft is inserted into the insertion groove of the upper door, and is exchanged and fixed in the left and right fixing groove The hinge shaft forms a lower hinge that is inserted into the insertion groove of the lower door, while forming a protective piece and a handle fixed to the left and right fixing grooves, and the upper and lower doors are formed so that the upper and lower doors can be opened and closed about the hinge axis of the hinge. It is characterized by.
