  • the water filled in the water supply passage 500 is supplied to the ice-maker 310 by pressure difference between the inlet side 610 and the outlet side 620 of the pump 600 driven.
  • the pump 600 when the pump 600 is driven by the operational signal of the ice-maker after the water in the water supply container 400 is fully exhausted, the water and air co-exists in the water supply passage 500 and thus the air may be introduced into the inlet side 610 of the pump 600.
  • the air in the water supply container 400 may be introduced into the pump 600 through the inlet passage 520.
  • the air introduced into the pump 600 may be directed toward the outlet passage 530.
  • the air discharged to the outlet passage 530 is introduced into the valve 700 through the outlet passage 530 and is then supplied to the ice-maker passage 540.
  • the air is filled in some of the suction passage 510, inlet passage 520, outlet passage 530, and ice-maker passage 540.
  • the pump 600 cannot generate pressure that can discharge the water remaining in the ice-maker passage 540. That is, it becomes an adverse water-supplying condition where the air-co-exists in both of the inlet side 610 and the outlet side 620 and thus the pump 600 cannot generate pressure for effectively supplying the water to the pump 600.
  • the pump 600 is designed to start operating at the same time the valve 700 is opened.
  • valve 700 and the pump 600 are located at a height lower than not only the water using device 250 but also the water supply container 400.
  • the valve 700 and the pump 600 are disposed adjacent to each other and maintain the interconnection state.
  • valve 700 is located at a height identical to or greater than the pump 600. As shown in Fig. 6 , the water remaining in the ice-maker passage 540 is introduced into the outlet side of the pump 600 through the valve upon opening the valve 700.
  • the water is introduced into the pump 600 when the valve 700 is opened. Accordingly, the inside of the pump 600 and the inlet and outlet sides 610 and 620 of the pump 600 can be quickly filled with the water.
  • the water can be supplied to the pump 600 when the valve 700 is opened, the adverse water supply condition in the water supply passage can be quickly eliminated. Therefore, the pump 600 can generate normal discharge pressure and thus the remaining water in the ice-maker passage 540 can be discharged. In addition, the water can be effectively supplied from the water supply container 400.
  • this principle can be identically applied to not only the ice-maker passage 540 but also the dispenser passage 550.
