<p>PROBLEM TO BE SOLVED: To reduce noise, improve durability and downsize by making a runner revolve at a low speed with a motor using a permanent magnet rotor in a pump for a washing machine which can store priming water in a pump case and autosuck from a water inlet provided in the pump case. SOLUTION: Priming water can be stored in a pump case 13 and a runner casing 14 in which a volute chamber 15 which communicates with a water inlet 22 is formed, is provided, and a runner 18 provided in the runner casing 14 in rotatable manner is driven with a motor 19 in a counterclockwise and clockwise rotatable manner. The runner casing 14 has an outlet which discharges a mixture of priming water and air from a water inlet 22, and a volute chamber 15 nearly symmetrical to the center of the outlet and the runner 18 is formed, by the clockwise or counterclockwise rotation of the runner 18, priming water and air from the water inlet 22 are mixed, and separated into water and air in the pump case for autosuction.</p> |
