沸かし器を実現することができる。As described above, according to the present invention, the circulating means for circulating the liquid in the container, the removing means for removing impurities in the liquid circulated by the circulating means, and the water quality of the liquid in the container are determined. A water quality judging means, a removing capacity judging means for judging whether or not the capacity of the removing means is present from the value obtained by the water quality judging means, an exchange notifying means for notifying replacement of the removing means, and a removing capacity judging means. By providing a replacement notification control means for outputting a control signal from the output to the replacement notification means, it is possible to judge that the capacity of the removing means is lost and notify the user, so that the user can obtain accurate water purification means. Therefore, it is possible to realize the electric water heater that can know the replacement time, prevent unnecessary expenses, and maintain a sufficient water purification capacity.

The water quality determining means, the removal capacity determining means for determining the presence or absence of the capacity of the removing means from the value obtained by the water quality determining means, and the control of the circulation means according to the output from the removal capacity determining means. By providing the circulation control means, it is possible to determine that impurities have adhered to the removal means and the water purifying ability has been lost, and thus the delivery of the liquid to the removal means can be stopped,
It is possible to realize an electric water heater that prevents the impurities adhering to the removing means from falling into the circulating liquid due to useless circulating purified water, and prevents useless consumption of electric power.
