发明名称 Scale deposition device and water heater
摘要 A water heater, which allows efficient deposition of a scale component dissolved in water so as to reduce adhesion of the scale to a heat-transfer channel. The water heater includes: scale deposition device including a tank, an anode and a cathode provided in the tank so as to be opposed to each other, and a first power supply for applying a voltage between the anode and the cathode, the scale deposition device depositing a scale component dissolved in water retained in the tank; a heat-transfer channel provided at downstream of the scale deposition device, for guiding the water; and a heat source for heating the water by heat exchange in the heat-transfer channel, in which the scale deposition device includes oxygen-gas supplying/dissolving means for supplying an oxygen gas to a water feed pipe for feeding the water to the tank and dissolving the oxygen gas in the water.

主权项 1. A scale deposition system, comprising: a first tank; a scale deposition device including an anode and a cathode provided in the first tank so as to be opposed to each other, and a first power supply that applies a voltage between the anode and the cathode thereby depositing a scale component dissolved in water retained in the first tank; a second tank; and a scale capturing device including at least one pair of anodes and cathodes provided in the second tank, and a second power supply that applies a voltage between the at least one pair of anodes and cathodes to form an electric field between the at least one pair of anodes and cathodes in the second tank, wherein the scale deposition device includes an oxygen-gas supplying/dissolving unit supplying an oxygen gas to a water feed pipe for feeding the water to the first tank and dissolving the oxygen gas in the water, and wherein the second tank is connected to the first tank to receive the scale component in the water, the scale component being attracted to one of the anode or cathode of the at least one pair of anodes and cathodes in the second tank.
