  2. In Article 1, A refrigerator in which the first hinge pin is located in front of the second hinge pin.
  3. In Article 1, A refrigerator in which the first hinge pin is located further from the center of the door than the second hinge pin.
  4. In Article 1, The first hinge pin extends further downward than the lower end of the second hinge pin, and A refrigerator in which a nut for height adjustment is coupled to the first hinge pin below the hinge plate.
  5. In Article 1, The first hinge pin extends downward and protrudes further than the hinge plate, and A refrigerator in which the lower end of the second hinge pin is formed so that its lower end is positioned inside the hinge plate.
  6. In Article 5, A second pin hole is formed through the hinge plate so that a second hinge pin is inserted therein, and A stepped portion with a larger diameter is formed on the lower surface of the hinge plate along the perimeter of the second pin hole, and A refrigerator in which the lower end of the second hinge pin is bent outward at the stepped portion to restrain the second hinge pin.
  7. In Article 6, A refrigerator having a protrusion formed on the second hinge pin that protrudes outward and contacts the upper surface of the hinge plate.
  8. In Article 6, A recess is formed in the center of the lower surface of the second hinge pin, and A refrigerator in which a bending portion is formed along the perimeter of the above-mentioned recess and contacts the above-mentioned step portion.
  9. In Article 8, A refrigerator in which the bending portion is located at a higher position than the open lower surface of the stepped portion.
  10. In Article 6, At the lower end of the first hinge pin, a coupling portion is formed that extends through the hinge plate and has screw threads formed on its outer surface, and A refrigerator in which a nut for fixing the height of the first hinge pin is fastened to the above-mentioned joint.

Description

Refrigerator The present invention relates to a refrigerator. Generally, a refrigerator is a home appliance designed to store food at low temperatures within an internal storage space enclosed by a door. To achieve this, the refrigerator is configured to maintain stored food in optimal conditions by cooling the interior of the storage space using cold air generated through heat exchange with a refrigerant circulating in a freezing cycle. Recent refrigerators are becoming increasingly larger and more multifunctional in line with changes in dietary habits and the trend toward product sophistication, and refrigerators with various structures designed with user convenience in mind are being released. In particular, recently, refrigerators are designed to be embedded in a wall or arranged to harmonize with other furniture or appliances. In this case, the refrigerator requires a certain distance to prevent the corner of the rotating door from interfering with adjacent walls, furniture, or appliances. To this end, a refrigerator is being developed in which the top and bottom of the refrigerator door are supported by multiple hinge pins, and the refrigerator door is opened and closed as the center of rotation changes. However, in the case of such a refrigerator, the spacing between multiple hinge pins is narrow, so impact may be applied to the hinge pins when operating to adjust the height of the door, and there is a problem in that normal opening and closing of the door becomes impossible due to deformation or breakage of the hinge pins caused by this. FIG. 1 is a perspective view of a refrigerator according to a first embodiment of the present invention. Figure 2 is a front view of the refrigerator with the door open. FIG. 3 is a partial perspective view showing the hinge of the refrigerator mounted above from below. FIG. 4 is a partial perspective view showing the combined structure of the door and the guide member. Figure 5 is a partial lower view of the above door. FIG. 6 is a plan view showing the arrangement of passes forming the guide groove of the guide member. FIG. 7 is a perspective view of the hinge above. FIG. 8 is an exploded perspective view of the hinge. Figure 9 is a cross-sectional view 9-9 of Figure 7. FIG. 10 is a drawing showing the process of joining the hinge pins of the hinge in sequence. FIG. 11 is a side view showing the height adjustment state of the door. FIG. 12 is an exploded perspective view showing the combined structure of a hinge and a guide member according to a second embodiment of the present invention. Fig. 13 is a cross-sectional view of 13-13 of Fig. 12. Specific embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not to be limited to the embodiments presented, and other inventions that are inferior or other embodiments included within the scope of the present invention can be easily proposed by adding, changing, or deleting other components. Before the explanation, directions are defined. In the embodiment of the present invention, the direction in which the front of the door shown in FIGS. 1 and 2 faces can be defined as the front, the direction toward the cabinet relative to the front of the door as the rear, the direction toward the floor surface where the refrigerator is installed as the downward direction, and the direction away from the floor surface as the upward direction. Additionally, when discussing directions that are not defined, the directions can be defined and explained based on each drawing. Furthermore, although the embodiment of the present invention describes a refrigerator in which a refrigerator compartment and a freezer compartment are arranged vertically and each is equipped with a door, it should be noted in advance that the present invention is not limited to the structure and form of the refrigerator and is applicable to all types of refrigerators having a rotating door. FIG. 1 is a perspective view of a refrigerator according to a first embodiment of the present invention. FIG. 2 is a front view of the refrigerator with the door open. As described, the refrigerator (1) according to an embodiment of the present invention may have an overall exterior formed by a cabinet (10) that forms a storage space with an open front and a door (20) that opens and closes the storage space. Additionally, the refrigerator (1) may be installed to harmonize with the furniture or walls of the indoor space. For example, a space corresponding to the size of the refrigerator (1) may be provided in the furniture or walls to accommodate the refrigerator (1), or it may be placed as a built-in type.
