Description

Upper and lower door lock of refrigerator

The present invention relates to an upper and lower door fixing device of a refrigerator, the refrigerator having a structure in which the upper and lower doors of the refrigerator are rotated and opened so as to have a fixing means which can be released so that the upper and lower doors can be integrally rotated and opened and closed if necessary. The upper and lower door fixing device of the refrigerator.

Typically, the home refrigerator 10 is largely divided into a freezing chamber 11, a refrigerating chamber 12, and the like, as shown in side cross-sectional view in FIG. 1, and a rapid freezing chamber 13, a vegetable chamber, or the like is formed. The refrigerator 10 has a rear duct 14 and a recovery duct 15 for circulating coolant and cool air in the rear to lower sides of the door 23, and the cooler 16 as the coolant circulator. , A compressor 19, a condenser (not shown), and the like.

In the refrigerator 10 having such a configuration, the saturated steam of a low boiling point refrigerant having the inside of the refrigerator 10 as a low heat source and the outside as a high heat source is compressed at a high pressure in the compressor 19 to flow to a condenser, In the condenser, latent heat of evaporation is released from the high-pressure and high-temperature refrigerant to a high-heat source outside the refrigerator, causing a phase change to a liquid refrigerant, and the liquid refrigerant is throttled to low pressure and low temperature through an expansion valve. That is, it flows into the cooler 16. The low-pressure and low-temperature refrigerant in the cooler 16 absorbs latent heat from the low heat source inside the refrigerator 10 in the liquid phase, causing a phase change to a saturated steam refrigerant, and then flowing back into the compressor 19 described above. This constitutes a circulation cycle of the refrigerant.

In the middle of repeating the circulation cycle of the refrigerant, internal air contacts the cooler 16 installed on the inside and the rear of the refrigerator 10 to form cold air, and the cold air is supplied by the fan motor 17 for supplying cold air. Passed through the back duct 14 and supplied to each freezing chamber 11, the refrigerating chamber 12, etc., the supplied cold air is recovered and circulated to the cooler 16 side again through the recovery duct 15 to each freezing chamber 11 By controlling the refrigerating chamber 12 and the like at a predetermined temperature, a desired refrigerating (long) effect is brought about.

In addition, the freezing chamber 11 and the refrigerating chamber 12 of the refrigerator 10 are generally configured to be opened and closed by the upper door 21 and the lower door 22 which rotate separately separately.

However, according to the upper door 21 and the lower door 22 of such a structure, when the user wants to organize and classify the storage of the freezer compartment 11 and the refrigerating compartment 12, or when cleaning the upper door 21 ) And the lower door 22 to open and close each door separately to prevent the effort, and to display the inside of the refrigerator, as well as to open the two doors separately frequently In order to maintain the open state, there are problems such as holding each other.

Accordingly, the present invention is to solve the above-described problem, in the refrigerator having a structure in which the upper and lower doors of the refrigerator are rotated and opened separately, it is necessary to rotate and open the upper and lower doors together. When there is a, there is an object to provide a top and bottom door fixing device of the refrigerator having a fixing means of the upper and lower doors to be removable, opening and closing the upper and lower doors integrally without opening and closing each.
