としない浄水器を提供することにある。However, when the tap water valve is operated while the "raw water / purified water" switching lever is set to the "purified water" side, electric power is always supplied to the entire electronic circuit. Power consumption increases, and as a result, it becomes necessary to frequently replace the internal dry battery and button battery. Such battery replacement work is very troublesome and poses a risk of electric shock in view of the installation environment of the water purifier.
In addition, the structure of the water purifier itself becomes difficult because it facilitates the battery replacement work and guarantees the water resistance of the battery replacement part, resulting in an increase in the cost of the water purifier. Therefore, an object of the present invention is to provide a water purifier having such a filter material exchange display function, which does not require battery replacement at its power source.
