WATER SUPPLY DEVICE OF AUTOMATIC ICE-MAKING DEVICE, AND REFRIGERATOR INCLUDING WATER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a water supply device of an automatic ice-making device which has a water storage container provided with a main tank portion for storing ice-making water and a measurement tank portion for storing ice-making water of a predetermined amount to be supplied to an ice tray in a divided manner, and a pump device for supplying compressed air to push out the ice-making water from the measurement tank portion, and in which a compressed air introduction passage of the water storage container is separably connected to an air discharge port of the pump device, and to provide a technology for preventing the ice-making water from reaching the pump device by attenuating backflow energy even when the ice-making water of the measurement tank portion flows back in the compressed air introduction passage due to oscillation in installing the water storage tank storing the ice-making water into a refrigerator.SOLUTION: An air lead-out passage for leading out the compressed air delivered from a pump device reaches an air discharge port of the pump device from a longitudinal passage through a lateral passage.SELECTED DRAWING: Figure 4
