2 . The dishwasher of claim 1 , wherein

the one solid detergent moved by the first ejector is located at a lowest position in the stack in the first storage compartment,

the first ejector is at a lower side of the first storage compartment, and

the first storage compartment includes a first storage compartment outlet, at a lower portion of the first storage compartment, through which the first ejector moves the one solid detergent to thereby be discharged to the outside of the first storage compartment.

3 . The dishwasher of claim 2 , wherein

the first ejector includes a cam member configured to rotate in a first rotational direction to move the one solid detergent located at the lowest position in the stack in the first storage compartment through the first storage compartment outlet.

4 . The dishwasher of claim 3 , wherein

the cam member includes a presser protruding in a radial direction of the cam member, and

the presser is configured to rotate in the first rotational direction to press the one solid detergent located at the lowest position in the stack in the first storage compartment in a direction perpendicular to a stacking direction of the stack.

5 . The dishwasher of claim 3 , wherein as the cam member rotates in the first rotational direction, the cam member is configured to guide a movement of solid detergents in the stack in the first storage compartment in a direction parallel to a stacking direction of the stack.

6 . The dishwasher of claim 3 , wherein a rotating shaft of the cam member is inside the first storage compartment and longitudinally extends in a direction perpendicular to a stacking direction of the stack in the first storage compartment.

7 . The dishwasher of claim 3 , wherein

the first ejector further includes a driving motor configured to generate a rotational force and a transmission member configured to transmit the rotational force generated by the driving motor to the cam member, and

a rotating shaft of the driving motor is perpendicular to a rotating shaft of the cam member.

8 . The dishwasher of claim 7 , wherein the transmission member includes a worm gear on the rotating shaft of the driving motor.

9 . The dishwasher of claim 3 , wherein

the automatic detergent dispenser further includes a seating member opening, and a seating member door configured to open and close the seating member opening, and

the automatic detergent dispenser is configured so that, in response to the seating member door opening the seating member opening, a solid detergent seated on the seating member is input into the tub.

10 . The dishwasher of claim 9 , wherein the seating member is disposed at a side of the first storage compartment in a direction perpendicular to a stacking direction of the stack in the first storage compartment and at a side of the second storage compartment in a direction perpendicular to a stacking direction of the stack in the second storage compartment.

11 . The dishwasher of claim 10 , wherein the cam member is configured to rotate toward a direction in which the seating member is disposed.

12 . The dishwasher of claim 9 , wherein

the seating member opening is configured to be opened in an upper to lower direction, and is at a lower end of a seating member inner space in which a solid detergent discharged to the outside of the first storage compartment or a solid detergent discharged to the outside of the second storage compartment is seated, and

the seating member is configured to allow a solid detergent seated on the seating member to be discharged from the seating member inner space and move in a direction corresponding to a stacking direction of the stack in the first storage compartment and a stacking direction of the stack in the second storage compartment.

13 . The dishwasher of claim 1 , wherein the automatic detergent dispenser further includes:

a holder configured to be movable toward the plurality of solid detergents in the stack in the first storage compartment in a stacking direction of the stack to allow the plurality of solid detergents in the stack to be maintained in a stacked state inside the first storage compartment.

14 . The dishwasher of claim 13 , wherein

the holder is movable from an upper side of the first storage compartment in an upper to lower direction along a stacking direction of the stack in the first storage compartment, and

the first ejector is at a lower side of the first storage compartment to move a solid detergent located at a lowest position in the upper to lower direction in the stack in the first storage compartment.

15 . The dishwasher of claim 14 , wherein

the door is movable to a first position in which the door is vertical and closes the tub, and a second position in which the door is not vertical and opens the tub,

when the door is in the first position, the holder is configured to press, by gravity, a solid detergent located at a highest position among the plurality of solid detergents in the stack in the first storage compartment, and

when the door is in the second position, the holder is configured to support the solid detergent located at a highest position among the plurality of solid detergents in the stack in the first storage compartment.

16 . A dishwasher comprising:

a tub;

a door configured to open and close the tub; and

an automatic detergent dispenser on the door and including:

a first storage compartment configured so that a plurality of solid detergents are stackable in a stack in the first storage compartment,

a second storage compartment spaced apart from the first storage compartment and configured so that a plurality of solid detergents are stackable in a stack in the second storage compartment,

a first ejector configured to move one solid detergent among the plurality of solid detergents in the stack in the first storage compartment so as to be discharged to an outside of the first storage compartment,

a second ejector configured to move one solid detergent among the plurality of solid detergents in the stack in the second storage compartment so as to be discharged to an outside of the second storage compartment,
