PUMP, AND WASHING MACHINE, HOT WATER SUPPLY DEVICE AND DISHWASHER USING THE SAME

PROBLEM TO BE SOLVED: To provide a pump capable of being miniaturized, improving the reliability and durability, and reducing the cost, and to provide a washing machine, a hot water supply device and a dishwasher using the same. SOLUTION: In this pump 1 wherein a motor part 10 composed of a brushless DC motor, a pump part 30 and a discharge port 40 are integrally mounted, in the motor part 10, a rotor 20 having a magnetic member 21 on an inner periphery of a stator 13 is rotatably supported on a fixed shaft 18 mounted on a center of the motor part 10, and a water passage 24 from a suction port 11 is formed near a rotating shaft 22 of the rotor 20, and in the pump part 30, an impeller 23 mounted on the rotor 20 is rotated to send the water flowing from an inflow passage 24 to the discharge port 40, the magnetic member 21 is axially movable by thrust by the rotation of the impeller 23, and a flow detecting sensor 17 is mounted on the motor part 10 for detecting the magnetism of the moved magnetic member 21.
