CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application claims priority under 35 U.S.C. 119 and 35 U.S.C. 365 to Korean Patent Application No. 10-2010-0086015 filed on Sep. 2, 2010, which is hereby incorporated by reference in its entirety. 
       BACKGROUND 
       [0002]    The present disclosure relates to a dish washer. 
         [0003]    In general, dish washers are appliances that spray washing water onto dishes on which food or garbage is stained to wash the dishes. 
         [0004]    In detail, according to such a dish washer, clean washing water is supplied using a sump disposed at a side of a washing bath, and then a washing water spraying mechanism sprays the washing water onto dishes within the washing bath to wash the dishes. The washing water used for washing the dishes is recovered into the sump, and then, the recovered washing water is supplied again into the washing water spraying mechanism through a filtering device disposed within the sump. 
         [0005]    When the dishes are washed through the above-described processes, the washing water existing in the washing bath and the sump is discharged to the outside. Here, the foreign substances filtered by the filtering device may be discharged together with the washing water to the outside of the dish washer. 
         [0006]    A reception structure in which dishes are received is applied to the washing bath. The reception structure may include a support structure for stably supporting the dishes. 
         [0007]    In a dish washer according to a related art, there is a limitation that it is difficult to receive dishes having various sizes into the washing bath having a limited size. 
         [0008]    That is, the washing bath according to the related art may be partitioned into predetermined spaces. Thin tableware such as dishes may be received in one space of the washing bath, and thick tableware such as bowl may be received in the other space. 
         [0009]    According to kinds of tableware used by a user, as necessary, the thin dishes should be washed or the thick bowls should be washed. 
         [0010]    However, the washing bath according to the related art may be limited to its receiving space according to a kind of dishes. Thus, there is a limitation that the spatial utilization of the washing bath is not effective. As a result, satisfaction of the product by the user may be reduced.

         [0034]    Hereinafter, a structure of a rack device will be described with reference to the accompanying drawings. A rack device  100  that will be described below may be applied to the upper rack  16  or the lower rack  17 . 
         [0035]      FIG. 2  is a perspective view illustrating a state in which a dish is received in a rack device according to the first embodiment. 
         [0036]    Referring to  FIG. 2 , the rack device  100  according to the first embodiment includes a receiving frame  110  defining a receiving space and a support part  120  for supporting a dish inside the receiving frame  110 . Here, the rack device  100  may be called a “receiving device” in that the rack device  100  receives the dish. 
         [0037]    The support part  120  extends upward from a bottom surface of the receiving frame  110  to support at least one side of the dish. The support part  120  may be movable with respect to a center of a rotation shaft. Also, the support part  120  may be provided in plurality on the rotation shaft. 
         [0038]    The support parts  120  may be spaced from each other in a plurality of rows. The plurality of support parts  120  aligned in two rows among the support parts disposed in the plurality of rows may be manipulated to receive the dish. That is, to stably receive the dish, the support parts  120  spaced from each other in the two rows may support one side and the other side of the dish. That is to say, the dish may be disposed between the support parts  120  aligned in the two rows. 
         [0039]    The rack device  100  includes a support coupling part  140  for coupling the plurality of support parts  120  aligned in the two rows to each other. In detail, the support coupling part  140  may be coupled to a rotation center of each of the support parts  120  disposed in the two rows. The support coupling part  140  may be provided in plurality. The plurality of support coupling parts  140  may be spaced from each other in one row (see  FIGS. 4 and 5 ). 
         [0040]    The dish receivable into the rack device  100  may include a first container  50  having a flat shape and a second container  60  having a thick shape. For example, the first container  50  may be a dish, and the second container  60  may be a bowl. Although the first and second containers  50  and  60  include the dish and bowl in the drawings, the first and second containers  50  and  60  may include containers having various shapes, i.e., a pot and a frying-fan. 
         [0041]      FIG. 3  is a perspective view illustrating one example of a manipulated state of a support part in the rack device according to the first embodiment.  FIG. 4  is a perspective view illustrating the other example of a manipulation state of the support part in the rack device.  FIG. 5  is a partially enlarged view illustrating a rotation state of the support part in the rack device according to the first embodiment.  FIG. 6  is a perspective view illustrating a state in which dishes having various sizes are received in the rack device according to the first embodiment. 
         [0042]    Referring to  FIGS. 3 to 6 , the rack device  100  according to the first embodiment includes a receiving frame  110  defining an outer appearance, a support part  120  disposed inside the receiving frame  110  to support a dish, and rotational central portions  131  and  132  providing rotation centers so that the support part  120  is movable. 
         [0043]    A plurality of wire frames may be coupled to each other with a predetermined distance to form the receiving frame  110 . The receiving frame  110  may include a side frame  111  having a predetermined height and a lower frame  112  for providing a dish seat part. 
         [0044]    A plurality of receiving parts are disposed in a receiving space defined by the receiving frame  110 . The plurality of receiving parts include a first receiving part  101  defined in a side of a lower portion of the receiving space, a second receiving part  102  defined in the other side of the lower portion of the receiving space, a third receiving part defined in a side of an upper portion of the receiving space, and a fourth receiving part  104  defined in the other side of the upper portion of the receiving space. 
         [0045]    The first, second, third, and fourth receiving parts  101 ,  102 ,  103 , and  104  may be disposed on both sides with respect to the support coupling part  140 , i.e., first and second accommodation parts  141  and  142  that will be described below, respectively, and thus be classified according to their positions. 
         [0046]    The plurality of receiving parts  101 ,  102 ,  103 , and  104  may be classified according to a kind of dish to be received. In detail, when the support part  120  is manipulated, i.e., when the support part  120  stands up or is laid down, a dish having a large width may be received into the first receiving part  101 , and a bowl having a large width may be received into the second receiving part  102 . Also, a dish having a large width such as a pot may be received into the third or fourth receiving part  103  or  104 . 
         [0047]    For example, when all of the support parts stand up, a dish having a large width may be received. Also, when a portion of the support parts  120  is laid down, a bowl having a slightly large width may be received. When all of the supports  120  are lied down, a dish having a very large width such as a pot may be received (see  FIG. 6 ). Hereinafter, an operation of a structure for supporting a dish will be described in detail. 
         [0048]    In the current embodiment, the first reception part  101  will be described as an example. That is, the current embodiment may be applied to the other receiving parts  102 ,  103 , and  104 . 
         [0049]    The first receiving part  101  includes a plurality of support parts  121  and  122  aligned in two rows and a plurality of rotation shafts defining a rotation center of each of the support parts  121  and  122 . 
         [0050]    Here, the plurality of support parts  121  and  122  disposed in the two rows may be called “support part assemblies”. In summary, the support part assemblies  121  and  122  may be understood that a plurality of support parts constituting one row are disposed in two rows. Although the support part assemblies include the support part  121  and  122  disposed in the two rows in  FIG. 3 , the support part assemblies may include the support parts  121  and  122  disposed in the two or more rows. 
         [0051]    The plurality of support parts  121  and  122  constituting one row (hereinafter, referred to as a “first row”) include the first and second support parts  121  and  122 . The first and second support parts  121  and  122  may be constituted by a plurality of extension parts extending upward from the lower frame  112 . 
         [0052]    For example, the first support part  121  includes a plurality of extension parts  121   a ,  121   b , and  121   c  (see  FIG. 5 ). The plurality of extension parts  121   a ,  121   b , and  121   c  are spaced a predetermined distance from each other. For example, the second support part  122  includes a plurality of extension parts  122   a  and  122   b  (see  FIG. 5 ). The plurality of extension parts  122   a  and  122   b  are spaced a predetermined distance from each other. 
         [0053]    A first rotational central portion  131  defining a rotation center of the first support part  121  is disposed under the first support part  121 . The first rotational central portion  131  may be rotated together with the first support part  121  in a clockwise or counter-clockwise direction. 
         [0054]    Also, a second rotational central portion  132  defining a rotation center of the second support part  122  is disposed under the second support part  122 . The second rotational central portion  132  may be rotated together with the second support part  122  in a clockwise or counter-clockwise direction. 
         [0055]    The first and second rotational central portions  131  and  132  may extend adjacent to each other in parallel or side by side. 
         [0056]    The support coupling part  40  may include the first accumulation part  141  for accumulating the first and second rotational central portions  131  and  132  at the same time. The first and second rotational central portions  131  and  132  may be rotated in a state where they are received into the first accumulation part  141 . 
         [0057]    The first and second rotational central portions  131  and  132  coupled to the first accumulation part  141  and the first and second support parts  121  and  122  rotated around the first and second rotational central portions  131  and  132  as rotation centers may constitute one row (hereinafter, referred to as a “first row”). 
         [0058]    The first and second rotational central portions  131  and  132  may be rotatably coupled to a support part holder  150 . That is, ends of sides of the first and second rotational central portions  131  and  132  may be coupled to the first accumulation part  141 , and ends of the other sides may be coupled to the support part holder  150 . 
         [0059]    An insertion hole (not shown) in which the first or second rotational central portion  131  or  132  is inserted may be defined in the support part holder  150 . When the first or second rotational central portion  131  and  132  is inserted, at least one portion of the support part holder  150  may be elastically deformed. 
         [0060]    The support coupling part  140  includes a second accumulation part  142 . The first accumulation part  141  is disposed on one side of the support coupling part  140 , and the second accumulation part  142  is disposed on the other side of the support coupling part  140 . The second accumulation part  142  may be coupled to the first and second rotational central portions  131  and  132  constituting the other row (hereinafter, referred to as a “second row”). 
         [0061]    That is, the first and second rotational central portions  131  and  132  coupled to the second accumulation part  142  and the first and second support parts  121  and  122  rotated with respect to the first and second rotational central portions  131  and  132  as rotation centers may constitute the second row. 
         [0062]    The support parts and rotational central portions provided on the second receiving part  102  may be separately operated with respect to the support parts  121  and  122  and the rotational central portions  131  and  132  of the first receiving part  101 . 
         [0063]    The rotational central portion of the second receiving part  102  is coupled to the first accumulation part  141  in a state where the second receiving part  102  is separated from the rotational central portions  131  and  132 . Thus, the rotational central portions  131  and  132  of the first receiving part  101  and the rotational central portions of the second receiving part  102  may be independently operated (rotated) with respect to each other. 
         [0064]    The rack device  100  includes a guide roller  115  for guiding the movement of the rack device  100 . The rack device  100  may be easily withdrawn to the outside of the tub  11  by the guide roller  115 . 
         [0065]      FIG. 3  illustrates a state in which the first and second support parts  121  and  122  disposed on the first receiving part  101  stand up, i.e., a state in which the first and second support parts  121  and  122  extend upward from the lower frame  112 . On the other hand,  FIG. 4  illustrates a state in which the first support part  121  is folded, i.e., a state in which the first support part  121  is rotated toward the lower frame  112  and the second support part  122  stands up. 
         [0066]    Referring to  FIG. 5 , structures and operations of the first and second support parts  121  and  122  will be described in detail. 
         [0067]    The first support part  121  includes the plurality of extension parts  121   a ,  121   b , and  121   c  extending upward from the first rotation central portion  131 . The extension parts include a first extension part  121   a , a second extension part  121   b , and a third extension part  121   c  which are spaced from each other. Here, the plurality of extension parts  121   a ,  121   b , and  121   c  may be called a “first support extension part”. 
         [0068]    In detail, the first extension part  121   a  and the second extension part  121   b  may parallelly extend spaced a distance (interval) L 1  from each other, and the second extension part  121   b  and the third extension part  121   c  may parallely extend a distance L 2  from each other. The first, second, and third extension parts  121   a ,  121   b , and  121   c  may be repeatedly provided in plurality. 
         [0069]    The distance L 2  may be twice as large as the distance L 1 . A dish may be received into a space between the extension parts having the distances L 1  and L 2  therebetween. 
         [0070]    The second support part  122  includes the plurality of extension parts  122   a  and  122   b  extending upward from the second rotation central portion  132 . The extension parts may include a fourth extension part  122   a  and a fifth extension part  122   b  which are spaced from each other. Here, the plurality of extension parts  122   a , and  122   b  may be called a “first support extension part”. 
         [0071]    In detail, the fourth and fifth extension parts  122   a  and  122   b  may be spaced a distance L 2  from each other and extend parallel to each other. The fourth and fifth extension parts  122   a  and  122   b  may be repeatedly provided in plurality. 
         [0072]    The distance L 3  may be twice as large as the distance L 1 . A dish may be received into a space between the extension parts having the distance L 3  therebetween. Here, the received dish may be a dish having a somewhat large width. The distances L 1 , L 2 , and L 3  may be called a “first distance”, a “second distance”, and a “third distance” for convenience, respectively. 
         [0073]    The first support part  121  may be rotated with respect to the first rotational central portion  131  in one direction (clockwise direction) or in the other direction (counter clockwise direction). Although the first support part  121  is folded while being rotated with respect to the first rotational central portion  131  in the counter-clockwise direction in  FIG. 5 , the first support part  121  may be folded while being rotated with respect to the first rotational central portion  131  in the clockwise direction. 
         [0074]    When the first and second support parts  121  and  122  stand up, the first and second extension parts  121   a  and  121   b  may be disposed between the fourth extension  122   a  and the fifth extension part  122   b . Also, the distance L 3  between the fourth extension part  122   a  and the fifth extension part  122   b  may be divided into three receiving spaces (dish support spaces) having a distance L 1  by the first and second extension parts  121   a  and  121   b.    
         [0075]    The distance L 2  between the second extension part  121   b  and the third extension part  121   c  may be divided into two receiving spaces (dish support spaces) having a distance L 1  by the fifth extension part  122   b.    
         [0076]    As described above, when the first and second support parts stand up, a dish having a somewhat small width may be received in the receiving space having the distance L 1 . 
         [0077]    As shown in  FIG. 5 , when the first support part  121  is folded and the second support part  122  stands up, a dish having a somewhat large width, e.g., a bowl may be received into the receiving space of the second support part  122  having the distance L 3 . 
         [0078]    On the other hand, when the first support part  121  stands up and the second support part  122  is folded, two kinds of dishes different from each other may be received into the receiving space having the distances L 1  and L 2 . That is, a dish having a first width may be received into the receiving space having the distance L 1 , and a dish having a second width greater than the first width may be received into the receiving space having the distance L 2 . 
         [0079]    As described above, dishes having sizes different from each other may be received according to manipulation positions of the first and second support parts  121  and  122 . 
         [0080]    That is to say, various dishes may be received according to whether the first and second support parts  121  and  122  stand up (are disposed on a first position) or are folded (are disposed on a second position). 
         [0081]    Thus, according to dishes to be washed, a user may selectively adjust a size of the receiving space (storing space) so that the first and second support parts  121  and  122  are disposed on adequate positions. 
         [0082]    Since the first and second rotational central portions  131  and  132  extend parallel to each other, when the first support part  121  is folded, the first support part may not interfere with the second support part  122  and be smoothly rotated until the first support part  121  reaches a position at which the first support part is folded. Similarly, the second support part  122  may not interfere with the first support part  121  and be rotated until the second support part  122  is folded. 
         [0083]      FIG. 6  illustrate a state in which containers  50 ,  60 , and  70  having various sizes are received into the rack device  100  through above-described manipulations. As shown in  FIG. 6 , the first container  50  having the smallest width (thickness) may be received into the third receiving part  103 , and the second container  60  having a width greater than that of the first container  50  may be received into the fourth receiving part  104 . Also, the third container having a width greater than those of the first and second containers  50  and  60  may be received into the first receiving part  101 . 
         [0084]    However, the present disclosure is not limited to the above-described receiving configuration. The received positions of the first, second, and third containers  50 ,  60 , and  70  may be varied according to the manipulation positions of the support parts  121  and  122 . 
         [0085]    Another embodiment will now be described. 
         [0086]    In third and fourth receiving parts according to the current embodiment, one rotational central portion is received into a receiving part, and a support part is coupled to the one rotational central portion. 
         [0087]    According to the above-described structure, when the support part stands up, a dish having a narrow width such as a plate may be supported. When the support part is folded, a dish having a wide width such as a bowl may be supported. 
         [0088]    However, on the other hand, each of the third and fourth receiving parts  103  and  104  may have the same structure as that of the first receiving part  101  described above. That is, in the third and fourth receiving parts  103  and  104 , a plurality of rotational central portions may be coupled to an accumulation part, and support parts different from each other may be rotatably coupled to each of the rotational central portions. 
         [0089]    Hereinafter, second and third embodiments will be described. The current embodiments are equal to the first embodiment except for a structure of a support part. Thus, different points therebetween will be mainly described and descriptions of the same parts will be quoted from descriptions and reference numerals of the first embodiment. 
         [0090]      FIG. 7  is a view of a support assembly in a rack device according to a second embodiment. 
         [0091]    Referring to  FIG. 7 , a rack device  100  according to a second embodiment includes a plurality of support parts  221  and  222  and a plurality of rotational central portions  231  and  232  respectively coupled to the plurality of support parts  221  and  222 . The plurality of rotational central portions  231  and  232  may be received first and second accumulation parts  141  and  142 , respectively. 
         [0092]    The plurality of support parts  221  and  222  may include a first support part  221  and a second support part  222  which include extension parts extending with the same distance as each other. 
         [0093]    In detail, the first support part  221  includes a plurality of extension parts extending with the same distance L 4  as each other. Here, the extension parts will be quoted from the descriptions of the first embodiment. Also, the second support part  222  includes a plurality of extension parts extending with the same distance L 5  as each other. 
         [0094]    When the first and second support parts  221  and  222  stand up, the extension parts (first support extension parts) constituting the first support part  221  and the extension parts (second support extension parts) constituting the second support part  222  may be alternately disposed. 
         [0095]    A distance L 6  spaced between the first support extension part and the second support extension part may be about half of the distance L 4  or L 5 . When all of the first support part  221  and the second support part  222  stand up, a dish having a size receivable into the distance L 6  may be supported. 
         [0096]    On the other hand, when one of the first and second support parts  221  and  222  is folded, a dish having a size receivable into the distance L 4  or L 5  may be supported. As described above, dishes different from each other may be selectively received according to the manipulation positions of the first and second support parts  221  and  222 . 
         [0097]      FIG. 8  is a view of a support part in a rack device according to a third embodiment. 
         [0098]    Referring to  FIG. 8 , a rack device  100  according to a third embodiment includes a first support part  321  rotatably disposed with respect to a first rotational central portion  331  as a rotation center and a second support part  322  rotatably disposed with respect to a second rotational central portion  332  as a rotation center. 
         [0099]    The first and second rotational central portions  331  and  332  may be rotatably coupled to first and second accumulation parts  141  and  142 . 
         [0100]    The first rotational central portion  331  may be inserted into the second rotational central portion  332 . That is, the first rotational central portion  331  is received into the second rotational central portion  332 . 
         [0101]    In detail, the second rotational central portion  332  has a guide hole  333  for guiding the rotation of the first support part  321 . 
         [0102]    The guide hole  333  may be a cut portion formed by cutting an outer surface of the second rotational central portion  332  in a radius direction. When the first support part  321  is rotated, the guide hole  333  may prevent the first support part  321  from interfering with the second rotational central portion  332 . 
         [0103]    Thus, the first and second support parts  321  and  322  may be independently operated without interfering with each other. Also, according to the manipulation positions of the first and second support parts  321  and  322 , dishes having various sizes may be received. 
         [0104]    In the dish washer according to the embodiments, the plurality of support parts may be rotatably disposed to define the receiving spaces having various sizes. Thus, as necessary, tableware having sizes different from each other may be received. 
         [0105]    Also, the plurality of rotation shafts that are used as rotation centers with respect to the plurality of support parts may be provided. Thus, the plurality of support parts may not interfere with each other and may be easily rotated in a state where the plurality of rotation shafts are received into one shaft accumulation part. 
         [0106]    Also, the plurality of rotation shafts that are used as rotation centers with respect to the plurality of support parts may be provided. Thus, the plurality of support parts may not interfere with each other and may be easily rotated in a state where one rotation shaft is received into the other rotation shaft. 
         [0107]    Therefore, since the user may manipulate the plurality of support parts into various shapes according to the tableware to be washed, the satisfaction of the product may be improved. 
         [0108]    According to the embodiments, since the receiving part of the rack device can receive dishes having various size, industrial applicability may be significantly high. 
         [0109]    Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
