doors door pockets 106 and 206 which may store the food. Specifically, thedoor pockets 106 and 206 may be mounted torespective dikes doors - The rotating
doors gaskets doors main body 10. Thegaskets - As shown in
FIG. 1 , the upper storage chamber 20 is not provided with a separate vertical partition wall, thereby enabling an inner space of the upper storage chamber 20 to be maximized. In addition, at least onedoor 100 of the plurality ofrotating doors filler 300 to seal a gap between the plurality ofrotating doors - As a non-limiting example, the
filler 300 is mounted to the leftrotating door 100 in an embodiment of the present disclosure shown inFIG. 1 , but the embodiment of the present disclosure is not limited thereto. For example, thefiller 300 may be mounted to the rightrotating door 200 or at least one of the plurality of rotating doors. - In this case, the
filler 300 may be rotatably mounted to the leftrotating door 100 through acoupling bracket 400. Thecoupling bracket 400 may include adike coupling portion 410 which is fixed to thedike 110 of the leftrotating door 100, and a filler coupling portion 420 which extends from thedike coupling portion 410. Thefiller 300 may be rotatably coupled to the filler coupling portion 420 of thecoupling bracket 400. - Meanwhile, the
main body 10 is provided with a guide portion 90 to rotate thefiller 300, and the guide portion 90 may include a guide body 91 and a guide groove 92 formed within the guide body 91. The guide portion 90 may be arranged at an upper end portion of the upper storage chamber 20. - The
filler 300 may include aguide protrusion 350 which is inserted into the guide groove 92 of themain body 10 to move along the guide groove 92. Theguide protrusion 350 may be arranged at an upper end portion of thefiller 300 so as to correspond to the guide groove 92. - Accordingly, the filler 30 may rotate in one direction so as to be tightly pressed against the
gaskets rotating doors rotating door 100, whereas the filler 30 may rotate in the other direction so as not to interfere with the rightrotating door 200 during opening of the leftrotating door 100. - Meanwhile, the sliding
doors 70 and 80 may be slidably coupled to themain body 10 by slidingdevices 71 and 81. Respective rear portions of the slidingdoors 70 and 80 may be provided withbaskets - The cold air supply device may include a compressor, a condenser, an expansion valve, an evaporator, a refrigerant tube, a blowing fan, and the like, and produce cold air through circulation of a refrigeration cycle of compressing, condensing, expanding, and evaporating a refrigerant.
- Since the above-mentioned
rotating door 100 to open and close the upper storage chamber 20 is supported by thehinges door 100 on the basis of the central plane thereof, a phenomenon may be caused which is deflected downwards at side portions opposite to thehinges door 100 by a load of thedoor 100 itself or a load of food stored in thedoor pocket 106 according to use of the refrigerator for long periods of time. - Since the
filler 300 mounted to therotating door 100 is also lowered in height when the deflection of the door is caused, a phenomenon may consequently be generated in which theguide protrusion 350 of thefiller 300 is not inserted into the guide groove 92 of themain body 10. Therefore, thefiller 300 may not be smoothly operated and the storage chamber 20 may not be sealed. - In order to prevent such a situation, the refrigerator according to the embodiment of the present disclosure has a structure to adjust a height of the
filler 300, which allows the height of the filler 30 to be uniformly maintained regardless of deflection of thedoor 100. -
FIG. 3 is a view illustrating the door and the filler in the refrigerator ofFIG. 1 .FIG. 4 is a side view illustrating a portion of the filler in the refrigerator ofFIG. 1 .FIG. 5 is a cross-sectional view illustrating a portion of the filler in the refrigerator ofFIG. 1 .FIG. 6 is an exploded view illustrating the filler in the refrigerator ofFIG. 1 .FIG. 7 is a view for explaining a function of a height adjustment portion of the filler in the refrigerator ofFIG. 1 . Hereinafter, for convenience of description, the leftrotating door 100 is simply referred to as “adoor 100” and the upper storage chamber 20 is simply referred to as “a storage chamber 20”. - Referring to
FIGS. 3 to 7 , thefiller 300 of the refrigerator according to the embodiment of the present disclosure includes aheight adjustment portion 380 to uniformly maintain the height of the filler 30 regardless of deflection of thedoor 100. - The
height adjustment portion 380 may be a protrusion which protrudes from a lower end portion of thefiller 300. Theheight adjustment portion 380 may come into contact with a bottom surface 21 (seeFIG. 7 ) of the storage chamber 20 when thedoor 100 is closed in a deflected state, whereas theheight adjustment portion 380 may not come into contact with the bottom surface 21 of the storage chamber 20 when thedoor 100 is closed in a non-deflected state. - Accordingly, when the
door 100 is closed in the deflected state, theheight adjustment portion 380 may be pressed from the bottom surface 21 of the storage chamber 20 while coming into contact with the same. - The height of the
filler 300 may be increased by pressing theheight adjustment portion 380 from the bottom surface 21 of the storage chamber 20, and theguide protrusion 350 of thefiller 300 may be easily inserted into the guide groove 92 of themain body 10. - In this case, only the
filler 300 may be lifted without lifting of thedoor 100 when they are somewhat loosely coupled to each other, whereas thedoor 100 and thefiller 300 may be simultaneously lifted when they are securely coupled to each other. - When only the
filler 300 is lifted without the lifting of thedoor 100, a relatively small load may be applied to the bottom surface 21 of the storage chamber. On the other hand, when all of thedoor 100 and thefiller 300 are simultaneously lifted, a relatively large load may be applied to the bottom surface 21 of the storage chamber, but a difference in height between the plurality ofdoors - This
height adjustment portion 380 may generally have a truncated cone shape. Accordingly, theheight adjustment portion 380 may have aflat surface 381 at a center thereof, and aninclined surface 382 formed around theflat surface 381. - When the
door 100 is closed in the deflected state, theinclined surface 382 collides with a front end portion of the bottom surface 21 of the storage chamber, thereby enabling thefiller 300 to be lifted. When thefiller 300 is fully lifted, theflat surface 381 is pressed against the bottom surface 21 of the storage chamber, thereby being able to be stably supported by the bottom surface 21 of the storage chamber. - Meanwhile, as shown in
FIG. 6 , thefiller 300 may be formed by assemblingcases heat insulator 330, and ametal plate 340. - The
cases first case 310 and asecond case 320. Each of thefirst case 310 and thesecond case 320 may be injection-molded with a resin material. - The
first case 310 may be provided with abracket coupling portion 311 to which thecoupling bracket 400 may be coupled. Thefirst case 310 may be coupled with theguide protrusion 350. - The
heat insulator 330 serves to thermally insulate the cold air within the storage chamber 20. Theheat insulator 330 may be arranged in a space defined between the first andsecond cases heat insulator 330 may be assembled between the first andsecond cases - The
metal plate 340 may be coupled to an outer side portion of thesecond case 320. Magnetic force of magnets (not shown) included in thegaskets doors metal plate 340. Thus, thefiller 300 may be pressed against thedoors - The
metal plate 340 may be coupled, at respective upper and lower end portions thereof, with anupper sealing member 360 and alower sealing member 370 which may seal gaps between thefiller 300 and themain boy 10. A heating element (not shown) to prevent dew formation may be arranged between themetal plate 340 and thesecond case 320. - Meanwhile, the
height adjustment portion 380 may be formed at a lower end portion of thefirst case 310, as shown inFIG. 6 . Theheight adjustment portion 380 may be injection-molded integrally with thefirst case 310 with a resin material. In this case, since the inner case of the bottom surface 21 of the storage chamber is also made of a resin material as described above, theheight adjustment portion 380 and the bottom surface 21 of the storage chamber are all made of a resin material, thereby enabling friction noise to be reduced. - However, unlike the above configuration, the
height adjustment portion 380 may be provided separately from thecases - Therefore, the
filler 300 of the refrigerator according to an embodiment of the present disclosure includes theheight adjustment portion 380 to uniformly maintain the height of thefiller 300, therefore, thefiller 300 may be smoothly operated regardless of deflection of thedoor 100. - Furthermore, since the
height adjustment portion 380 may be integrally formed during molding of thecase 310 of thefiller 300 and be supported by the bottom surface 21 of the storage chamber 20 without a separate support, the height of thefiller 300 according to the embodiment of the present disclosure may be easily adjusted. - As is apparent from the above description, a filler may be maintained at a proper height in spite of deflection of a door. Accordingly, in spite of the deflection of the door, the filler may be smoothly operated and cold air in a storage chamber may be prevented from escaping.
- In addition, height adjustment of the filler may be easily realized through a relatively simple shape of the filler, not through a complex machine.
- Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
