First Claim
1. A dishwasher comprising:
- a tub including a space in which dishes are washed;
a sump to contain washing water to be supplied into the tub; and
a descaling solution supply device to supply a descaling solution to the sump,wherein the descaling solution supply device includes;
a main flow path to guide washing water supplied to the sump;
a solution accommodating unit to contain a descaling agent including a solution outlet through which washing water, in which the descaling agent is dissolved, is discharged to the main flow path;
a solution discharge valve to open and close the solution outlet; and
a branch flow path which branches off from the main flow path, supplies the washing water into the solution accommodating unit, and includes an atmosphere communicating port that communicates with the atmosphere,wherein the descaling solution supply device comprises;
an accommodating unit main body including the solution accommodating unit and the main flow path; and
a main body cover coupled to the accommodating unit main body and forms the branch flow path,wherein the solution accommodating unit is open at an upper side thereof, andwherein the main body cover covers the upper side of the solution accommodating unit.

3. A dishwasher comprising:
-
a tub including a space in which dishes are washed; a sump to contain washing water to be supplied into the tub; and a descaling solution supply device to supply a descaling solution to the sump, wherein the descaling solution supply device includes; a main flow path to guide washing water supplied to the sump; a solution accommodating unit to contain a descaling agent including a solution outlet through which washing water, in which the descaling agent is dissolved, is discharged to the main flow path for supplying to the sump; a solution discharge valve to open and close the solution outlet; a branch flow path which branches off from the main flow path, supplies the washing water into the solution accommodating unit, and includes an atmosphere communicating port that communicates with the atmosphere; a water supply device to supply the washing water to the main flow path; and a controller that controls the water supply device to supply the washing water while the solution discharge valve is closed, wherein the branch flow path comprises; an upstream side branch flow path which guides washing water flowing upward from the main flow path; and a downstream side branch flow path which guides the washing water downward along the upstream side branch flow path, wherein a water level in the downstream side branch flow path is restricted to a predetermined height by atmospheric pressure applied through the atmosphere communicating port, and wherein the descaling solution supply device further comprises; an accommodating unit main body including the solution accommodating unit and the main flow path; and a main body cover coupled to the accommodating unit main body and forms the branch flow path, wherein the solution accommodating unit is open at an upper side thereof, and wherein the main body cover covers the upper side of the solution accommodating unit. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
