Title:
WATER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2023005109
Kind Code:
A
Abstract:
To suppress large difference between a detection value detected by a first flow sensor and a detection value detected by a second flow sensor, in a case where a rotation speed of an impeller of a first electric pump and a rotation speed of an impeller of a second electric pump are the same.SOLUTION: When the operating state of a first electric pump 3 and the operating state of a second electric pump 5 are the same, a sensor correction unit 7B can execute correction such that a detection value detected by a first flow sensor Fs1 and a detection value detected by a second flow sensor Fs2 are the same. Consequently, a pump control unit 7A related to a water supply device 1 does not need to perform different controls depending on whether the first electric pump 3 is used to supply water or the second electric pump 5 is used to supply water.SELECTED DRAWING: Figure 1
