Description

technical field [0001] The invention relates to an electric water heater, in particular to an instant high-frequency eddy current electric water heater. Background technique [0002] At present, there are mainly three types of water heaters on the market: gas water heaters, solar water heaters and storage-type electric water heaters. Gas water heaters are gradually fading out of the water heater market due to their safety hazards and higher and higher usage costs. Because solar water heaters are strictly affected by weather, climate and installation conditions, it is difficult for them to occupy a larger market share. Due to the large size, long warm-up time and low heat application rate, storage-type electric water heaters are no longer suitable for the rhythm of modern life. [0003] Chinese patent CN1626986 discloses a water pipe-type electric water heater for washing and bathing, which includes a control circuit containing a high-frequency resonant coil, and a section ...
