2. Description of the Related Art Due to recent deterioration of tap water quality and improvement of health consciousness, more delicious water has been demanded, and development of products which can provide delicious water and hot water has been desired. A water purifier is one of them, but a water heater is also required to have a water purifying function.As a method, conventionally, water in a container is boiled, and the water in the container, trichlormethane, which is said to be a carcinogen, musty odor and musty odor. Was removed.

However, in this method, if the boiling time is prolonged, a large amount of steam is emitted, which is dangerous in handling, and the life of components such as resin is shortened. In addition, some substances are difficult to remove by boiling alone, so that they were incomplete as water purifying means. Therefore, a water heater provided with a water purifying means using activated carbon or the like has been developed, and the provision of delicious water has been realized (for example, JP-A-2-36820, JP-A-4-4-2).
No. 92120).

Hereinafter, a conventional electric water heater will be described. As shown in FIG. 4, while the water in the container 51 is poured from the hot water supply port 52 to the water purification means 53 by the electric pump provided in the lead-out path provided in the container 51, In the configuration in which the water is purified, the water poured into the container 51 is heated by turning on the heating element to become hot water, and when the temperature reaches a predetermined temperature, the electric pump is automatically operated, and the hot water is discharged as described above. It was configured to be refluxed.

However, in the above-described conventional configuration, the hot water supply port 52 is provided on the container 51 side, and the water purification means 53 is provided on the lid side. There is no problem because the circulating hot water enters the water purification means 53 directly from the hot water supply port 52, but during circulation, the lid is opened or removed, and the hot water supply port 52 and the water purification means 53 are separated. In this case, hot water jumps out of hot water supply port 52,
Since it is in a state of being poured into the container 51, the operator may be scalded by boiling water and may be anxious to the user due to the possibility of the burn. Nevertheless, circulating hot water has a problem in that it is inefficient, such as lowering the temperature of hot water.
