WATER CLEANER

摘要

PROBLEM TO BE SOLVED: To provide a water cleaner in which mutual interference between a magnetic substance for detecting a cartridge and a magnetic substance for detecting flow rate is prevented or suppressed to improve detection accuracy. SOLUTION: The water cleaner 1 has a filtration cartridge 4 which is freely detachably attached to a water cleaner main body 3 and filters raw water introduced inside the cartridge and a means for calculating integrated flow rate of water caused to flow in the filtration cartridge 4 after beginning of using the filtration cartridge 4. The water cleaner 1 is provided with a first magnetic substance 25A which is mounted on the filtration cartridge 4 and enables life-expiring integrated flow rate of the filtration cartridge 4 to be discriminated and a second magnetic substance 22 which is mounted on the water cleaner main body 3 and calculates integrated flow rate of water caused to flow in the filtration cartridge 4, and leaked magnetic flux from the first magnetic substance 25A at a position of the second magnetic substance 22 is set to be a prescribed value or below.
