Since the content liquid penetrates and passes through the purification material through the grids and the porous portions of the 26 until it is below the bottom of the purifier 623 and touches the purification material sufficiently, the content liquid is sufficiently purified in the hot water storage to remove odors. It is possible to remove harmful chlorine compounds such as trihalomethane. Due to this purification function, the purifier 62
3 is more advantageous as it is closer to the bottom.

Moreover, since the content liquid is actively convected by heating, especially by boiling, it is possible to promote the passage of the content liquid to the purifying material and to purify the entire content liquid evenly.

In addition to such purifying action, the control circuit 42 makes the content liquid boil for a predetermined time at a predetermined time or at a predetermined time, or by repeating the boiling, to emit odors and harmful substances. Can be used together.

By the way, it is rarely used in a state where the content liquid is considerably small, and even if it is continued to be used as it is, it can be sufficiently purified by then, so that the purifier 623 is almost the same. It is sufficient if it is provided below the intermediate water level.

The purifier 623 is held in the inner container 31 and can be attached / detached to / from the container 1 together with the inner container 31 and the content liquid discharge passage 33. The purifier 26
The cleaning of 3 itself can be easily performed regardless of the side of the body 1, and there is no problem even if it is on the lower side, and it can always be used in a clean and effective state.
