[0008]
The cation exchange resin is housed in a case through which water can pass, and is detachably attached to the lid.
[0009]
According to the present invention, with such a configuration, when hot water heated to an appropriate temperature is poured into a hot water receiving portion of a substantially concave lid, the hot water passes through a hole provided in a bottom portion of the hot water receiving portion. Then, it passes through the cation exchange resin stored in the case and is stored in the inner container.
[0010]
At that time, sodium ions in the cation exchange resin show an exchange reaction with cations such as calcium and magnesium in the hot water, and calcium and magnesium ions are taken into the cation exchange resin, and conversely, sodium ions are Released. The calcium and magnesium ions are removed from the hot water stored in the inner container in this way, so that soft water with low hardness can be obtained, and abundant sodium ions effective for heat retention and moisture retention can be obtained.
