       FIG.  1    is a side cross-sectional view of a dishwasher according to an embodiment of the disclosure. 
     Referring to  FIG.  1   , a dishwasher  1  may include a housing  10  forming an exterior thereof. The dishwasher  1  may include a tub  12  arranged inside the housing  10 . The tub  12  may be formed in a substantially box shape. A front surface of the tub  12  may be opened. That is, the front surface of the tub  12  may correspond to an opening  12   a.    
     The dishwasher  1  may include a door  11  configured to open and close the opening  12   a  of the tub  12 . An upper portion and a lower portion of the door  11  may be hinged to the housing  10  so as to open and close the opening  12   a  of the tub  12 . However, the disclosure is not limited thereto, a side portion of the door  11  may be hinged to the housing  10  so as to open and close the opening  12   a  of the tub  12 . Alternatively, the door  11  may be installed in the housing  10  through an opening and closing structure rather than the hinge. 
     The dishwasher  1  may further include a storage container arranged in the tub  12  to accommodate dishes. The storage container may include a plurality of baskets  51 ,  100 , and  53 . 
     The plurality of baskets  51 ,  100 , and  53  may be arranged in a vertical direction Z of the dishwasher  1 , and correspond to a lower basket  51 , a middle basket  100 , and an upper basket  53  in order from bottom to top. A lower guide rack  13   b  may be provided to support the lower basket  51 , and a middle guide rack  13   a  may be provided to support the middle basket  100 . The upper basket  53  may be formed in the form of a rack assembly, and thus dishes having a relatively small volume may be accommodated therein. The middle guide rack  13   a  and the lower guide rack  13   b  may be installed on a side surface of the tub  12  to be slidable in a front and rear direction X toward the opening  12   a  of the tub  12 . 
     However, the disclosure is not limited thereto, and the upper basket  53  may not be included according to the size of the tub  12 . Accordingly, the storage container may include only the middle basket  100  and the lower basket  51 . 
     The dishwasher  1  may include a sump  300  provided to store washing water. The dishwasher  1  may include a washing chamber C, which is a space formed by the inside of the tub  12 . 
     The washing chamber C is a space in which dishes placed on the baskets  51 ,  100 , and  53  may be washed by washing water and dried. The washing chamber C may be defined as an inner space of the tub  12  formed by side surfaces, a rear surface, and a lower surface  12   b  of the tub  12  and the sump  300  communicating with the lower surface. The washing water circulated in the washing chamber C may be discharged to the outside of the washing chamber C only through the sump  300  rather than other components. 
     The dishwasher  1  may include a plurality of arm assemblies  41 ,  42 , and  43  configured to spray washing water toward the baskets  51 ,  100 , and  53  so as to wash dishes stored in the baskets  51 ,  100 , and  53 . The arm assemblies  41 ,  42 , and  43  may be arranged in the vertical direction Z of the dishwasher  1 , and correspond to a first arm assembly  41 , a second arm assembly  42 , and a third arm assembly  43  in order from bottom to top. The first arm assembly  41  may be arranged under the lower basket  51 , the second arm assembly  42  may be arranged under the middle basket  100 , and the third arm assembly  43  may be arranged above the upper basket  53 . 
     Particularly, the second arm assembly  42  may be fixed to a lower side of the middle basket  100 , and in response to separating the middle basket  100  from the middle guide rack  13   a , the second arm assembly  42  together with the middle basket  100  may be separated from a duct  60 . 
     However, the disclosure is not limited thereto. For example, the second arm assembly  42  may be arranged above the middle basket  100 . In addition, when the upper basket  53  is omitted, the third arm assembly  43  may be arranged above the middle basket  100 . 
     The first arm assembly  41  may be configured to be rotated about a rotating shaft  41   a , the second arm assembly  42  may be configured to be rotated about a rotating shaft  42   a , and the third arm assembly  43  may be configured to be rotated about a rotating shaft  43   a.    
     Unlike the second arm assembly  42  and the third arm assembly  43 , the first arm assembly  41  may be fixed to one side of the sump  300  and arranged on the lower surface  12   b  of the tub  12 . In certain embodiments, the first arm assembly may be fixed to a single side of the sump  300 . 
     The dishwasher  1  may include a circulation pump  30  configured to pump washing water, which is stored in the sump  300 , or washing water, which is introduced into the inside of the dishwasher  1  from an outside, to the arm assemblies  41 ,  42 , and  43 . The washing water pumped by the circulation pump  30  may be supplied to the first arm assembly  41  through an alternating device  200  connected to the circulation pump  30  or moved to an upper side by the duct  60  and then supplied to the second arm assembly  42  or the third arm assembly  43 . 
     The alternating device  200  may supply washing water to the first arm assembly  41  through a connector  400  connected to the first arm assembly  41  and may supply washing water to the duct  60  through a flow path  62  connected to the duct  60 . 
     The dishwasher  1  may include the connector  400  connecting the alternating device  200  and the first arm assembly  41 . One end of the connector  400  may communicate with the alternating device  200 , and the other end of the connector  400  may communicate with the first arm assembly  41 . Therefore, as described above, the washing water pumped by the circulation pump  30  may be introduced into the alternating device  200 , and the washing water moved to the connector  400  by the alternating device  200  may be sprayed to the lower basket  51  through the first arm assembly  41 . 
     However, the disclosure is not limited thereto, and the circulation pump  30  may be directly connected to the connector  400  and thus the washing water pumped by the circulation pump  30  may be directly introduced to the first arm assembly  41  through the connector  400  without passing through the alternating device  200 . In this case, the dishwasher  1  may not include the alternating device  200 . 
     The dishwasher  1  may include a drain hose (not shown) provided to drain washing water remaining inside the tub  12 . The drain hose may be connected to the sump  300  to drain the washing water stored in the sump  300  to the outside of the dishwasher  1 . 
     As described above, the washing water collected in the sump  300  may be purified by a filter (not shown) inside the sump  300  and circulated back into the washing chamber C by the circulation pump  30 . 
     In a machine room L formed in a lower portion of the dishwasher  1 , the above-described configuration such as the circulation pump  30 , the alternating device  200 , and the sump  300  may be arranged.

Particularly, the support tine  142  may support a ball of a wine glass held on the upper holder frame  130  so as to prevent the wine glass held on the upper hold frame  130  from shaking. The support tine  142  may be connected to the second frame body  141  and protrude from the second frame body  141 . The support tine  142  may include a plurality of support tines  142 . A gap between the two adjacent support tines  142  may correspond to a holding groove  144 , and dishes such as a plate may be arranged and supported in the holding groove  144  formed between the two adjacent support tines  142 . The holding groove  144  may include a plurality of holding grooves  144 , and widths of the plurality of holding grooves  144  may be the same or different. 
     The support tine  142  may include a bending member  142   a  and a support member  142   c . The bending member  142   a  may be provided in plurality. The plurality of bending members  142   a  may be arranged in a line to form a line including at least one bending point  142   aa , and may be connected to each other in the arranged state. In other words, the support tine  142  may include a plurality of bending points  142   aa . At this time, a portion of the support tine formed by the plurality of bending members  142   a  that is arranged and connected in one line may be referred to as an extension  142   b . The plurality of bending members  142   a  may be arranged on one plane M. That is, the extension  142   b  including the plurality of bending points  142   aa  may lie on one plane M. 
     The support tine  142  may include the support member  142   c  in contact with a ball of a wine glass. The support member  142   c  may be connected to the second frame body  141  through the plurality of bending members  142   a . In other words, the support member  142   c  may be connected to the second frame body through the extension  142   b.    
     As mentioned above, as the support tine  142  includes the plurality of bending points  142   aa , the support tine  142  may be provided in such a way that a curved surface thereof is in close contact with a surface of a plate or a portion of the curved surface is inserted into a concave bowl so as to more stably support dishes including a plate and a bowl. 
     The support member  142   c  may be bent at the extension  142   b . Particularly, because the extension  142   b  is formed by connecting the plurality of bending members  142   a , the extension  142   b  may lie on the plane M, on which the plurality of bending members  142   a  is arranged, and the support member  142   c  may be bent from other end of the extension  142   b , which is opposite to one end of the extension  142   b  connected to the second frame body  141 , to substantially upward Z so as not to lie on the plane M on which the plurality of bending members  142   a  is arranged. In other words, the support member  142   c  may be formed to protrude from the other end of the extension  142   b  toward a direction approaching the upper holder frame  130 . 
     The lower holder frame  140  may include the connection tine  143  connected to a rotating device  150 . The connection tine  143  may be connected to one end of the second frame body  141 . The connection tine  143  may be pressed and rotated by the rotating device  150 . An operation of the connection tine  143  and the rotating device  150  will be described later in detail. 
     When the lower holder frame  140  is viewed from the front side X, a straight line l passing through the connection tine  143  may form a predetermined angle β with the plane M, on which the extension  142   b  is arranged. In other words, the connection tine  143  may not lie on the plane M. The second frame body  141 , the support tine  142 , and the connection tine  143  may be integrally formed with each other. 
     The basket  100  may include the binder  160  provided to allow the lower holder frame  140  to be rotatably coupled to the basket body  110 . Particularly, the binder  160  may allow the lower holder frame  140  to be rotatably coupled to the bottom of the basket body  110 . The binder  160  may include a plurality of binders  160 . 
     The binder  160  may include a binder body  161  in which a plurality of binding grooves  164  and  165  is formed, a clamp  162  formed in a lower portion of the binder body  161 , and a connection member  163  connecting the binder body  161  and the clamp  162 . 
     The plurality of binding grooves  164  and  165  may include a first binding groove  164  into which the second frame body  141  is inserted, and a second binding groove  165  into which one wire  110   a  of the wires forming the basket body  110  is inserted. Because the first binding groove  164  and the second binding groove  165  are parallel to each other, the wire  110   a  parallel to the second frame body  141  may be inserted into the second binding groove  165 . The lower holder frame  140  in a state in which the second frame body  141  is inserted into the first binding groove  164  may be rotatable, and the second frame body  141  may form a rotation axis of the lower holder frame  140 . 
     The clamp  162  may be coupled to one wire  110   b  of the wires forming the basket body  110 . Particularly, the wire  110   b  perpendicular to the wire  110   a  inserted into the second binding groove  165  may be inserted into and coupled to a fastening space  162   a  between the binder body  161  and the clamp  162 , and the binder  160  may be fixed to the basket body  110 . The wire  110   a  inserted into the second binding groove  165  and the wire  110   b  inserted into the fastening space  162   a  may be included in the wires  110   a  and  110   b  forming the bottom of the basket body  110 . 
     The binder  160  may be arranged behind the adjacent support tine  142 . In other words, between the binder  160  and the support tine  142  adjacent to the binder  160 , the binder  160  may be arranged closer to the rotating device  150 . Particularly, the connection member  163  of the binder  160  may be arranged between the wire  110   b  inserted into the fastening space  162   a  of the binder  160  and the support tine  142  adjacent to the binder  160 . However, the disclosure is not limited thereto, and the binder  160  may be arranged in front of the adjacent support tine  142 . 
     Meanwhile, the connection tine  143  may be inclined toward the center of the second frame body  141  by a predetermined angle α with respect to a straight line perpendicular to the second frame body  141 . Particularly, the connection tine  143  may be inclined at 3° with respect to a straight line perpendicular to the second frame body  141 . 
     In addition, a step may be formed in a middle portion of the connection tine  143 . Particularly, the connection tine  143  may include a first member  143   a  connected to one end of the second frame body  141  and extending to be inclined in the direction of the center of the frame body by a predetermined angle α with respect to the straight line perpendicular to the second frame body  141 , a step member  143   b  bent at an end of the first member  143   a  toward a direction opposite to the inclined direction of the first member  143   a  and extending substantially parallel to the second frame body  141 , and a second member  143   c  extending from an end of the step member  143   b  toward a direction away from the second frame body  141  to be approximately parallel to the first member  143   a  and then coupled to the rotating device  150 . 
     In response to the connection tine  143  being coupled to the rotating device  150  in a state in which the lower holder frame  140  is coupled to the basket body  110  by the binder  160 , the connection tine  143  may be pulled to a direction opposite to the inclined direction of the connection tine  143 , and thus the connection tine  143  in an elastically deformed state may be coupled to the rotating device  150 . At this time, by the elastic restoring force, the second frame body  141  connected to the connection tine  143  may be pulled in a rearward direction with respect to  FIG.  2    by the connection tine  143 . That is, the second frame body  141  may be pulled in a direction toward the rotating device  150 . 
     In response to the second frame body  141  being pulled, the support tine  142  may be also moved. However, because the connection member  163  of the binder  160  is arranged between the adjacent support tine  142  and the wire  110   b  inserted into the fastening space  162   a , the binder  160  may be prevented from being rearwardly moved by the support tine  142 , and the movement of the support tine  142  may be limited by the binder  160 . That is, even when the restoring force of the connection tine  143  acts, the support tine  142  and the second frame body  141  may not be moved in the direction toward the rotating device  150 . In addition, because the binder  160  and the support tine  142  adjacent to the binder  160  are firmly fixed in contact with each other by the restoring force of the connection tine  143 , the coupling of the binder  160 , the basket body  110 , and the lower holder frame  140  may be stronger. 
     The basket  100  may include the rotating device  150  configured to rotate the lower holder frame  140 . 
     The rotating device  150  may include a slide button  151  to which one end of the connection tine  143  is coupled and provided to press the connection tine  143 , and a rotating device body  152  coupled to the basket body  110  and including a guide rail  152   c  to which the slide button  151  is inserted and coupled. 
     The slide button  151  may include a button body  151   a  provided to be gripped by a user, and a coupling rib  151   b  protruding from a rear surface of the button body  151   a  to form a coupling groove  151   c . One end of the connection tine  143  may be inserted and coupled into the coupling groove  151   c . Particularly, the connection tine  143  may be arranged at a rear of the rotating device  150 , and the connection tine  143  arranged at the rear of the rotating device  150  may be inserted into the coupling groove  151   c  located at the rear of the button body  151   a.    
     The rotating device body  152  may include a plate-shaped body plate  152   a , a plurality of couplers  152   b  protruding from the body plate  152   a  and coupled to the basket body  110 , and the opening-shaped guide rail  152   c  formed on the body plate  152   a  and extending in the left and right direction Y. The slide button  151  may be inserted into the guide rail  152   c  and slid in the left and right direction Y along the guide rail  152   c . The slide button  151  may be operated manually but is not limited thereto. Alternatively, the sliding button  151  may be automatically slid by a separate power source, controller, inputter, and power transmission mechanism. 
     As the slide button  151  slides, the slide button  151  may press the connection tine  143  connected to the slide button  151  in a sliding direction and may rotate the connection tine  143  in the direction of pressing the connection tine  143 . 
     In response to the rotation of the connection tine  143 , the second frame body  141  connected to the connection tine  143  and the support tine  142  connected to the second frame body  141  may also rotate together. In other words, by sliding the slide button  151  to a predetermined position, the lower holder frame  140  may be rotated to allow the support tine  142  to be positioned to correspond to dishes including a wine glass held on the upper holder frame  130 . 
     The rotating device body  152  may include an indicator  153  provided on a front surface of the rotating device body  152 . When the slide button  151  reaches a position in which the indicator  153  is placed, the lower holder frame  140  may be rotated and the indicator  153  may indicate the size of wine glass or cup corresponding to the lower holder frame  140 . The indicator  153  may be arranged above the guide rail  152   c.    
     The indicator  153  may include the shape of dishes including a wine glass, a cup, and the like, and the indicator  153  may be provided in plurality. The indicator  153  may be displayed in the rotating device body  152  in such a way that the indicator  153  is printed, embossed or engraved on the front surface of the body plate  152   a , and a portion of the body plate  152   a  is cut out such as a stencil plate. However, the disclosure is not limited thereto, and the indicator  153  may be provided on the rotating device body  152  in various ways. 
     The rotating device body  152  may include a mounting rib  154  protruding backward from the rear surface of the body plate  152   a , and including a plurality of mounting grooves  154   a  to which the connection tine  143  rotated by the slide button  151  is mounted. 
     The mounting rib  154  may include the plurality of mounting grooves  154   a  and a rib  154   b  between two adjacent mounting grooves  154   a . In other words, the mounting groove  154   a  may correspond to a space between two adjacent rib  154   b . The plurality of mounting grooves  154   a  may correspond one by one to the indicator  153 . Accordingly, the mounting groove  154   a  may be arranged under the corresponding indicator  153 . 
     A side end of the rib  154   b  may be rounded to have a curved shape to allow the connection tine  143  to escape from the mounting groove  154   a  when the connection tine  143  mounted to one mounting groove  154   a  starts to move to another mounting groove  154   a  by the slide button  151 . 
     The rib  154   b  may protrude further rearward than the mounting groove  154   a , and thus a degree of deformation of the connection tine  143  placed at the rib  154   b  may be greater than the connection tine  143  placed at the mounting groove  154   a . Accordingly, an additional force for elastic deformation of the connection tine  143  may be required to move the connection tine  143 , which is mounted on the mounting groove  154   a , to the rib  154   b , and thus even when a rotational force caused by a weight of the dishes is transmitted to the connection tine  143  through the support tine  142  and the second frame body  141 , it is difficult for the connection tine  143  to be easily separated from the mounting groove  154   a  and to be moved to the rib  154   b.    
     Therefore, when the connection tine  143  is mounted on the mounting groove  154   a , it is possible to prevent that the lower holder frame  140  is unintentionally rotated by the weight of dishes such as wine glasses, and accordingly, it is also possible to prevent unintentional movement of the connection tine  143  and the slide button  151 . 
       FIG.  11    is a cross-sectional view taken along a line XI-XI′ when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at a third position P 3 .  FIG.  12    is a cross-sectional view taken along a line XII-XII′ when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at the third position P 3 .  FIG.  13    is a cross-sectional view taken along the line XI-XI′ when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at a first position P 1 .  FIG.  14    is a cross-sectional view taken along the line XI-XI′ when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at a second position P 2 .  FIG.  15    is a view illustrating a state in which a slide button  151  is at the first position P 1 , the second position P 2 , and the third position P 3  in the basket  100  shown in  FIG.  2   . 
     Referring to  FIGS.  11  to  15   , a state in which the slide button  151  is moved to a leftmost position inside the guide rail  152   c  may be referred to as a first position P 1 , a state in which the slide button  151  is moved to a rightmost position may be referred to a second position P 2 , and a state in which the slide button  151  is approximately at a center of the guide rail  152   c  may be referred to a third position P 3 . 
     Further, a position of the lower holder frame  140  and a position of the support tine  142  when the slide button  151  is placed at the first position P 1  may be referred to as the first position P 1 . A position of the lower holder frame  140  and a position of the support tine  142  when the slide button  151  is paced at the second position P 2  may be referred to as the second position P 2 . A position of the lower holder frame  140  and a position of the support tine  142  when the slide button  151  is paced at the third position P 3  may be referred to as the third position P 3 . 
     However, the disclosure is not limited thereto, and the slide button  151  may be positioned only at the first position P 1  or the second position P 2 , or may be positioned at various positions between the first position P 1  and the second position P 2  according to the purpose of the manufacturer and the user. 
     In response to the slide button  151  being positioned at the first position P 1 , a distance between one end of the lower holder frame  140  and one end of the upper holder frame  130  that support dishes is increased in comparison with the state of being positioned at the second position P 2  or the third position P 3 . Particularly, in response to the slide button  151  being positioned at the first position P 1 , a distance between one end of the holding tine  133 , in which the holding groove  134 , on which the dish is held, is formed, and one end of the support member  142   c  of the support tine  142  supporting the dish held on the holding groove  134  is increased in comparison with the state of being positioned at the second position P 2  or the third position P 3 . In other words, the support tine  142  of the lower holder frame  140  being positioned at the first position P 1  may be closer to the bottom of the basket body  110  in comparison with the second position P 2  or the third position P 3 . At this time, a distance between one end of the support member  142   c  and one end of the holding tine  133  may be referred to as a first distance d 1 . 
     Accordingly, in response to the lower holder frame  140  being positioned at the first position P 1 , dishes such as a large wine glass may be stably held between the lower holder frame  140  and the upper holder frame  130 . In addition, in a side region D of the support member  142   c  of the lower holder frame  140 , a side surface of dishes such as cups placed on the bottom of the basket body  110  may be supported by the support member  142   c , thereby being stably placed in the basket body  110 . 
     In response to the slide button  151  being positioned at the second position P 2 , the distance between one end of the lower holder frame  140  and one end of the upper holder frame  130  that support dishes is reduced in comparison with the state of being positioned at the first position P 1  or the third position P 3 . Particularly, in response to the slide button  151  being positioned at the second position P 2 , a distance between one end of the holding tine  133 , in which the holding groove  134 , on which the dish is held, is formed, and one end of the support member  142   c  of the support tine  142  supporting the dish held on the holding groove  134  is reduced in comparison with the state of being positioned at the first position P 1  or the third position P 3 . In other words, the support tine  142  of the lower holder frame  140  being positioned at the second position P 2  may be further from the bottom of the basket body  110  in comparison with the first position P 1  or the third position P 3 . At this time, a distance between one end of the support member  142   c  and one end of the holding tine  133  may be referred to as a second distance d 2 . 
     Therefore, in response to the lower holder frame  140  being positioned at the second position P 2 , dishes such as a small wine glass may be stably held between the lower holder frame  140  and the upper holder frame  130 . In addition, dishes such as plates may be arranged and supported in the holding groove  144  between the support tines  142 . 
     In response to the slide button  151  being positioned at the third position P 3 , the distance between one end of the lower holder frame  140  and one end of the upper holder frame  130  which support dishes is less than the state of being positioned at the first position P 1  and greater than the state of being positioned at the second position P 2 . Particularly, in response to the slide button  151  being positioned at the third position P 3 , a distance between one end of the holding tine  133 , in which the holding groove  134 , on which the dish is held, is formed, and one end of the support member  142   c  of the support tine  142  supporting the dish held on the holding groove  134  is less than the state of being positioned at the first position P 1  and greater than the state of being positioned at the second position P 2 . In other words, the support tine  142  of the lower holder frame  140  being positioned at the third position P 3  may be further from the bottom of the basket body  110  in comparison with the first position P 1  and may be closer to the bottom of the basket body  110  in comparison with the second position P 2 . At this time, a distance between one end of the support member  142   c  and one end of the holding tine  133  may be referred to as a third distance d 3 . 
     Therefore, in response to the lower holder frame  140  being positioned at the third position P 3 , medium-sized dishes such as a wine glass or cup may be stably supported between the lower holder frame  140  and the upper holder frame  130 . 
     As described above, by operating the slide button  151  to be positioned at one of the first position P 1 , the second position P 2 , and the third position P 3 , it is possible to adjust the rotation of the lower holder frame  140 , and it is possible to arrange the lower holder frame  140  according to dishes held on the upper holder frame  130 . In other words, by operating the slide button  151  to be positioned at one of the first position P 1 , the second position P 2 , and the third position P 3 , it is possible to adjust the rotation of the lower holder frame  140 , and it is possible to adjust the distance between one end of the lower holder frame  140  and one end of the upper holder frame  130 . 
     However, the disclosure is not limited thereto, and the distance between one end of the lower holder frame  140  and one end of the upper holder frame  130  may be adjusted by the rotation of the upper holder frame  130 . Because the upper holder frame  130  is rotatably provided on the basket body  110  as described above, the distance between one end of the upper holder frame  130  and one end of the lower holder frame  140  may vary according to the degree of rotation. Particularly, the upper holder frame  130  may be rotated from a position, in which a downward rotation of the upper holder frame  130  is limited by the stopper, to a position, in which the upper holder frame  130  is perpendicular to the ground. As the upper holder frame  130  is positioned at arbitrary position between the position, in which the downward rotation of the upper holder frame  130  is limited by the stopper, and the position, in which the upper holder frame  130  is perpendicular to the ground, the distance between one end of the support member  142   c  of the lower holder frame  140  and one end of the holding tine  133  of the upper holder frame  130  may be adjusted. 
     In this case, the lower holder frame  140  may be stationary or may be rotated by the rotating device  150 . The upper holder frame  130  may include a separate connection tine connected to the first frame body  131  and an additional rotating device coupled to the connection tine. 
       FIG.  16    is a view illustrating a state in which dishes are held when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at the third position P 3 .  FIG.  17    is a view illustrating a state in which dishes are held when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at the first position P 1 .  FIG.  18    is a view illustrating a state in which dishes are held when the lower holder frame  140  of the basket  100  shown in  FIG.  2    is at the second position P 2 . 
       FIGS.  16  to  18    illustrate a state in which a wine glass is supported, but this is merely exemplary. Alternatively, other dishes including cups and the like may be supported, and a larger number of dishes may be supported. In addition, as for a wine glass, the support member  142   c  of the support tine  142  may be in contact with an inner surface of a ball of the wine glass to support the wine glass, or may be in contact with an outer surface of the ball of the wine glass to support the wine glass. 
     As is apparent from the above description, a dishwasher may include a lower holder frame including a plurality of support tines, so as to stably support dishes. 
     Further, because a position of a lower holder frame is adjusted according to the type and size of dishes, a dishwasher may support the dishes having various types and sizes. 
     Although a few embodiments of the 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. 
     Although the present disclosure has been described with various embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
