Referring to FIGS. 2 and 3, the present embodiment describes, by way of example, a storage chamber 111 that is selectively opened and closed by the middle door 13.
In detail, the rear surface of the middle door 13 is connected with a main container 15 that receives foods or containers, wherein the main container 15 is received in the storage chamber 111 that is defined in the main body 11. The one side of the inside of the main container 15 may be provided with an auxiliary container 17 for receiving foods or beverage containers. The inside spacer of the main container 15 except for the space in which the auxiliary container 17 is received may be provided with a separate auxiliary cooling chamber 18. The auxiliary cooling chamber may be provided with a bottle chamber 181 in which beverage bottles are loaded and stored and a quick cooling chamber 182 for quickly cooling beverages.
In addition, the middle door 13 is tiltably connected to the front surface of the main container 15 and tiltably connected from a vertical state to a horizontal state by a hinge 16. The upper surface of the middle door 13 may be depressedly formed with a gripping groove 133 at a predetermined depth. Herein, the bottom surface of the middle door 13 may be formed with the gripping recess like the gripping groove 133 instead a handle 131 of the middle door 13. As a result, the front portion of the middle door forms a smooth plane, such that the exterior of the refrigerator 10 can be processed more sharply.
Moreover, the front surface of the main container 15 is formed with a front hole 151 for drawing out the auxiliary container 17. The front surface of the main container 15 corresponding to the front surface of the auxiliary cooling chamber 18 is formed with a hole that receives beverage bottles into the bottle chamber 181 and a door that opens and closes the quick cooling chamber 182.
Meanwhile, both side portions of the main container 15 is provided with rails 19 and the inside surface of the storage chamber 111 is provided with a rail guide (not shown) that guides the front and rear direction movements of the rail 19.
With the refrigerator having the above-mentioned configuration, the middle door 13 can be horizontally tilted to draw out the auxiliary container 17 in the state where the main container 15 is completely drawn in the inside of the storage chamber 111. In addition, the main container 15 is drawn out by pulling the middle door 13 in a vertical state, such that the auxiliary container 17 can be drawn out. In this case, the auxiliary container 17 can be drawn out by a lifting operating through the upper opening portion of the main container 15. The operation method will be described in more detail below with reference to the accompanying drawings.
Meanwhile, the rear surface of the middle door 13 is formed with a latch 134 and the front surface of the main container 15 may be formed with a latch hole 152 in which the latch 134 is inserted. Therefore, when the user grips the gripping groove 133 formed on the upper surface of the middle door 13 and then pulls it forward, the latch 134 is out of the latch hole 152, such that the middle door 13 can be tilted in a horizontal state. The latch 134 is operated as a general hanging means but may be used as a one-touch button manner. For example, by a pressing and releasing action onto the front surface of the middle door 13 in the state where the middle door 13 is closely attached to the front surface of the main container 15, the latch 134 may be out of the latch hole 152. The rotational shaft portion of the middle door 13 is inserted with an elastic member such as a torsion spring and a hydraulic damper structure, such that the middle door 13 can be automatically rotated to a horizontal state. This structure is frequently applied to a home bar structure for a refrigerator in the related art and therefore, the detailed configuration thereof will be omitted. However, it is noted that the spirit of the present invention can apply the above-mentioned one-touch button and the automatic rotating function.
FIG. 4 is a perspective view showing a shape where a receiving rack of the refrigerator according to the embodiment of the present invention is drawn out.
Referring to FIG. 4, a receiving rack of the refrigerator can be drawn out from the main container 15 by the operation that rotates the middle door 13 in a horizontal state and then draws out the auxiliary container 17 forward. The foods and the beverage container received in the auxiliary container 17 can be taken out.
In detail, the middle door 13 is tilted forward by the operation that inserts fingers in the gripping groove 133 formed on the upper surface of the middle door 13 and pulls it, or by the pressing and releasing action onto the front surface of the middle door 13 as described above. Then, the middle door 13 becomes a horizontal state and in this state, the auxiliary container 17 can be drawing out through the front hole 151 of the main container 15. When the middle door 13 is tilted in a horizontal state, the bottle chamber 181 is exposed, such that the beverage bottles received in the bottle chamber 181 can be easily taken out. In addition, when the middle door 13 rotates horizontally, the front portion of the quick freezing chamber 182 is exposed, such that the user can quickly cool beverage bottles by putting the beverage bottles in the quick cooling chamber 182.
Further, the rear surface of the middle door 13, that is, the surface corresponding to the upper surface when the middle door 13 is in the horizontal state, is formed with a cup supporting groove 132 on which a cup is placed. Therefore, after the user places a cup on the cup supporting groove 132, he/she can pour and drink beverages in the cup. In other words, the middle door 13 also performs the home bar function.
FIG. 5 is a perspective view showing a shape where a basket of the refrigerator according to the embodiment of the present invention is drawn out.
Referring to FIG. 5, when the user pulls the handle 131 formed on the front surface of the middle door 13, the middle door 13 is drawn out forward in a vertical state. Herein, the handle 131 is formed at a position close to the lower end of the middle door 13, such that the middle door 13 cannot be tilted by a force pulling the handle 131. Alternatively, the bottom surface portion of the middle door 13 is formed with a groove such as the gripping groove 133, such that the middle door 13 cannot be rotated during a process of drawing out the middle door.
In detail, when articles to be drawn out by the user exist the rear end area of the auxiliary container 17, it may be more convenient that the user draws out the main container forward rather than tilting the middle door 13. In this case, the user can operate the middle door 13 so that the middle door 13 and the main container 15 are drawn out forward together.
Meanwhile, when the containers, in which beverages are received, are stored in the storage chamber 111 at a time, it is easy to draw out the containers as well as since the storage positions of the beverage container are not confused, such that the use convenience is increased.
FIG. 6 is a partial perspective view of a refrigerator according to another embodiment of the present invention.
Referring to FIG. 6, the embodiment is characterized in that the main container 15 is removed from the above embodiment and the middle door 13 is rotatably provided to the front surface of the main body 11 by the hinge 16.
In detail, the auxiliary container 17 is received in the storage chamber 111 formed in the main body 11 and the storage chamber 111 is selectively shielded by the middle door 13. The bottle chamber 181 and the quick cooling chamber 182 may be provided in the storage chamber 111. Therefore, the bottle chamber 181 and the quick cooling chamber 182 are not drawn out forward and may be fixed in the storage chamber 111.
Further, the rear surface of the middle door 13 may be formed with the latch 134 and the front surface of the main body 11 may be formed with the latch hole 112. The structure of the latch 134 and the latch hole 112 can perform the same configuration and function as one described in the above embodiment and the rotational shaft of the middle door 13 may be provided with the elastic member or the hydraulic damper.
With the structure, when the foods and containers are stored in the deep spots of the storage chamber 111, the disadvantages in that it is difficult for the user to find the foods and containers and take out them can be improved. In other words, the auxiliary container 17 can be drawn out such that the foods or the containers stored in the auxiliary container 17 can be confirmed from the outside of the main body 11. Therefore, it can be immediately confirmed which spots the stored foods or the containers are positioned.
