The water purifier is a filter material such as granular, fibrous activated carbon, or ceramic that is filled in the container to adsorb and remove chlorine contained in the water. An undersink type installed under a sink is often used, but recently, a combination of a water purifier with a water heater for hot water supply to a bathtub, etc. has been proposed. See, for example, JP-A-3-129244.

That is, if the water used in the water electrolysis apparatus 10 is changed from acidic water to alkaline water, it is possible to regenerate the filter material in the same manner as above with heated alkaline water.
In addition, the operation of the water electrolysis device 10 is stopped and the three-way valve 2
By switching 2, the water bypassing the water purifier 25 and the electrolytic cell 12 from the water supply pipe 19 can be heated as it is in the heat exchanger 2 and used for regeneration of the filter material.

However, if the temperature is rapidly raised from room temperature to this temperature, cracks and other problems occur. In some cases, in order to prevent this, the control procedure of gradually raising the temperature can be performed by controlling the hot water temperature in the water heater body 1.

うこともできる。As described above, the present invention has the following effects. The filter material of the water purifier combined with the water heater can be backwashed with hot water heated by the heat exchanger of the water heater to regenerate the adsorption capacity, thus extending the service life of the filter material and thus the filter. The number of times of replacement can be reduced without increasing the filling amount of the material, and the water purifier can be downsized. The filter material can also be sterilized during the regenerating operation.
