Description

Refrigerator with multi-directional retractable door

The present invention relates to a refrigerator, and more particularly to a multi-directional openable door to prevent the loss of cold air by minimizing the opening of the refrigerator door according to the storage position of the food in the refrigerator can be changed to the minimum required portion. Genie is about a refrigerator.

1 is a perspective view showing a conventional refrigerator.

Typically, a home refrigerator has an upper door 11 for opening and closing a freezer compartment and a lower door 12 for opening and closing a refrigerating compartment, and has a refrigerant circulation system such as a compressor, a condenser, a fan mutter, and an evaporator. By such a configuration, the refrigerant is compressed and condensed in the compressor and the condenser to liquefy, the liquid refrigerant is evaporated in the evaporator, and the fan motor is operated to quickly absorb the latent heat of the refrigerant as the vaporization heat of the refrigerant.

The compressor is turned on until the temperature of the refrigerating chamber reaches a predetermined value (usually 4 to 5 ° C.), lowers the temperature in the freezer compartment and the refrigerating chamber, and turns off when the temperature is reached. After that, when the temperature of the refrigerating chamber becomes more than a predetermined value, the compressor fan motor is operated again to repeat the temperature adjustment operation. The time required for one repetition is usually about 30 minutes.

On the other hand, the upper door 11 and the lower door 12 to maintain the airtight by using the magnetized packing to block the leakage of the refrigerant, each is mounted to open to one side by the upper and lower hinges (13).

In a conventional refrigerator having such a configuration, when the food is put into and taken out of the freezer compartment or the refrigerating compartment, the doors 11 and 12 need to be completely opened in order to reach the space on the side where the hinge 13 is formed (right side in the city). Due to the loss of the operation frequency of the above-mentioned refrigerant circulating system is increased and there is a disadvantage that goes against power saving.

In addition, since the doors 11 and 12 open only to one side, the opening side of the food access path increases the difference in storage temperature as the doors 11 and 12 open more frequently, thereby lowering the freshness of the food.

In addition, since only one hand is used to open the doors 11 and 12, the degree of discomfort is increased according to the user, and as the use becomes more frequent, fatigue and monotony cannot be avoided.

Accordingly, the present invention provides a refrigerator having a multi-directional openable door to prevent the loss of cold air by minimizing the opening of the refrigerator door according to the storage position of the food in the refrigerator to the minimum opening in the necessary couple. The purpose.

The present invention is applied to the refrigerator for storing food in the interior of the refrigerator opening and closing the upper door 11 and the lower door 12, the upper interior surface 10 and the doors 11 and 12 in the freezer compartment and the refrigerating compartment. It is a main point to provide an exercise device composed of a slide table 21, a first link 22, a second link 24, a support member 28, a hinge 29, and the like, between the inner upper end surfaces of the upper surface.

At this time, the slide 21 of the present invention is installed in the arc-shaped shape having a predetermined curvature on the high inner surface 10, the guide groove 21a of the same curvature is formed.

The slide table 21 uses a steel plate having a predetermined thickness (for example, 3 mm or more), and is a guide groove 21a having a curvature coinciding with the trajectory of the optical hole 24a of the second link 24 to be described later. ). The high inner surface 10 should be provided with a frame (not shown) for fixing the slide 21, and a space for moving the roller 25 to be described later on the slide 21.

In addition, the present invention provides a first link 22 made of a pair of members rotatably mounted to the high inner surface 10 via one end of a boss 23 and having a through hole 22a formed at the other end thereof. use.

The first link 22 cuts a steel plate having a predetermined thickness (for example, 5 mm or more) to a predetermined width (for example, about 10 mm), and then fixes the boss 23 at one end by fixing the middle and other ends. The through hole 22a for hardening the link shaft 26 and the protruding pin 27 which are mentioned later, respectively is processed. The boss 23 is a portion that is rotatably pushed to the high inner surface 10 using an axis (not shown).

In addition, the present invention uses a second link 24 which is connected between the first links 22 via a link shaft 26 and a through hole 24a is formed at the center thereof.

Like the first link 22, the second link 24 also has a structure in which a through hole 24a for cutting the steel plate material to a predetermined width and then firmly attaches the link shaft 26 to the middle and both ends thereof. The first link 22 and the second link 24 are assembled in an H shape and rotatable about each boss 23.

In addition, the present invention uses a connecting means for supporting the first link (22) and the second link (24) to be able to swing along the slide (21).

Since the first link 22 and the second link 24 must support the loads of the doors 11 and 12, the excessive bending moment acts on the boss 23 so that the rotation is not smooth when the amount of deflection increases. The amount of deflection is minimized by connecting the slide table 21 so as to be supported through the connecting means.

At this time, the connecting means is a roller 25 which is installed to move along the groove on the upper surface of the slide 21, and the guide groove 21a of the slide 21 in the through hole 24a of the second link 24 Link shaft 26 is connected to the roller 25 via the ().

At this time, the support member 28 has a slot 28a formed therein and sliding grooves 28b formed on both sides thereof, and passes through the slot 28a in the through hole 22a of the first link 22. The sliding motion is limited by the protruding pins 27 mounted.

The support member 28 has a structure in which a sliding groove 28b in which the tip of the first link 22 is accommodated is processed therein, and a slot 28a penetrating the sliding groove 28b is processed in both sides. It is also possible to process the slot 28a on the side after bending a steel sheet having a thickness (e.g., 3 mm or more) into a cross-sectional shape.

The protruding pins 27 are used last in the process of mounting the doors 11 and 12 to the refrigerator main body, and the support member 28 is inserted into the first link 22 and then the first link 22 of the first link 22 is removed. It press-fits into the through-hole 22a. Both ends of the protruding pins 27 move on the slots 28a of the support member 28. When the doors 11 and 12 are closed in FIG. 3, they come to the far right and the doors 11 and 12 are opened as far as possible. If you come to the far left.

4a, b, and c are shown a perspective view showing the open state of the door according to the present invention, respectively, and reference numerals 2 and 3 are used for unused reference numerals.

FIG. 4a shows the upper door 11 opened to the left side. As the roller 25 moves to the left side of the slide table 21, the first link 22 retreats slightly on the support member 28 and the support member ( 28 is pivoted slightly around the hinge 29 so that the upper door 11 is opened while moving in parallel.

FIG. 4B shows the lower door 12 opened to the right. The roller 25 moves to the right side of the slide 21 and the lower door 12 moves in parallel by the same motion as in FIG. 4A. do.

4c shows the state in which the doors 11 and 12 are pulled forward as a whole, with the roller 25 in the center of the slide 21 and without the support member 28 pivoting about the hinge 29. Since only the first link 22 is retracted as much as possible on the support member 28, the doors 11 and 12 are opened while being moved in parallel.
