[0002] As we all know, in the field of household appliances, gas water heaters are essential household appliances in people's daily lives. With the continuous updating of water heater functions and technologies, existing water heaters are no longer limited to a single hot water bathing function, and the functional requirements for water heaters are getting higher and higher. In view of the increasing demand for healthy bathing, a variety of water heater products with hydrogen-rich water bathing functions have emerged in the market. Then, when the existing hydrogen-rich water gas water heater device is used for normal bathing, the hydrogen content of the bathing water will be insufficient due to insufficient hydrogen supply, or the mixing of hydrogen and water in the transmission pipeline will be insufficient, resulting in an unsatisfactory hydrogen-rich bathing experience. Therefore, in the hydrogen-rich gas water heater device, the hydrogen content of the bathing water will be insufficient due to insufficient hydrogen supply, or the mixing of hydrogen and water in the transmission pipeline will be insufficient, resulting in an unsatisfactory hydrogen-rich bathing experience. In the control device of the water heater, the control structure of the circuit can be more intelligent. While ensuring the stable combustion of the gas water heater, the working condition of the hydrogen production supply component can be detected in real time to ensure the circulation supply of hydrogen-rich water, the stability of the hydrogen-rich bath, and the full mixing of hydrogen with the water in the waterway to obtain sufficient hydrogen-rich bathing. It is convenient to use a hydrogen-rich water gas water heater for bathing. Therefore, an intelligent gas water heater control device can be designed to calculate the working conditions of gas combustion in real time. At the same time, the hydrogen generated by the hydrogen production module can be fully mixed with the water in the waterway in time to ensure the circulation supply and the stability of the hydrogen-rich bath.

[0028] refer to Figure 1-2 In a preferred embodiment, the first pipeline is used to connect the water branch. Specifically, the water flow direction of the water branch is three-way valve 1 (that is, the first three-way valve) → electrolyzer → water pump → one-way valve 2 (that is, the second one-way valve) → three-way valve 2 (that is, the second three-way valve) → water outlet.
