Title:
LIQUID CIRCULATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/190790
Kind Code:
A1
Abstract:
A liquid circulating device comprises a liquid circuit (2), a first pump (5), and a second pump (6) for suctioning liquid from an inlet port (100) and discharging the liquid toward an outlet port (101) by causing an impeller (34) to rotate using an electric motor (32, 40) provided with a magnet (32) and a stator (40). The second pump (6) is equipped with a stator (40), a rotor (30) integrated with a magnet (32) and the impeller (34), a shaft (20), and a casing (10). The casing (10) is provided with the inlet port (100) and the outlet port (101). When the second pump (6) is stopped, the rotor (30) is moved to a first position farther from the inlet port (100) due to the attraction force between the stator (40) and the magnet (32), and when the second pump (6) is operating, the rotor (30) is moved to a second position closer to the inlet port (100) than the first position due to the difference in pressure between the inlet port (100) and the outlet port (101).
