Description

Technical Field

[0002] Instant electric water heaters are water heaters that can quickly heat running water through electronic heating components and can control water temperature, flow rate, power, etc. through circuits to make the water temperature reach a temperature suitable for human bathing. It heats up immediately without waiting, and heating can usually be started within a few seconds.

[0003] Among the related technologies, a solution for an instant water heater (announcement number: CN218864475U) was found through searching. When in use, the structure of the cold water inlet pipe, heating component, circulation component and hot water outlet pipe can effectively solve the problem of temperature rise when the water is stopped in the instant water heater, and can maximize the guarantee that the water outlet temperature meets the user's usage needs, which can effectively improve the user's comfort.

[0004] However, the heating body in the above-mentioned heating assembly can heat a separate hot water chamber. However, since the water temperature of the above-mentioned heating assembly may be unstable when in use, the start-stop switch control valve can control the opening and closing of the heating assembly. When using hot water, the switch control valve needs to be closed and opened. If the heating body is closed for a long time, the hot water inside the hot water chamber will become cold. Therefore, when the hot water is used for the second time, the heating body needs to be used to reheat the hot water inside the hot water chamber, resulting in a slow heating speed, and the water source cannot be heated sequentially, which wastes resources and cannot achieve energy saving and environmental protection.
