Problems solved by technology
[0002] Household gas water heaters have to face many uncontrollable factors in the process of use, such as the fluctuation of influent water flow, the purity of combustion gas, the pressure range of combustion gas, and the excessive wind pressure caused by external wind. It may affect the constant temperature performance of the gas water heater or cause the gas water heater to fail to work normally
Among them, problems such as the narrow intake pipe of the user's home lead to problems such as the pressure of the combustible gas delivered to the gas water heater is not within a reasonable range and the composition of the combustible gas is impure, which will lead to problems with the constant temperature performance of the water heater.

Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] This embodiment provides a method for detecting whether the combustion gas of a gas water heater is standard, wherein the gas water heater is mainly aimed at conventional domestic gas water heaters, and the structure of such gas water heaters can be found in figure 1 As shown, it includes a burner, an igniter for igniting the burner, a combustion proportional valve for controlling the amount of combustion gas entering the combustion chamber, a fan for controlling the amount of air entering the combustion chamber, and a combustion proportional valve for controlling The main control board for current value, fan speed and igniter opening and closing, and the water outlet valve connected with the main control board. In an embodiment, the main control board is pre-stored with a corresponding relationship table between the theoretical current...

The invention relates to a method for detecting whether the combustion gas of a gas water heater is standard. The gas water heater comprises a combustor, an igniter, a combustion proportional valve, a fan, a main control panel and a water outlet valve connected with the main control panel, wherein a corresponding relation table between a combustion proportional valve theoretical current range value and actual combustion power under the condition that the combustion gas is standard is pre-stored in the main control panel. The method is characterized by obtaining the combustion proportional valve theoretical current range value according to the current actual combustion power, then judging whether the actual current value of the combustion proportional valve is in the combustion proportional valve theoretical current range value, and detecting the problem of low constant-temperature performance caused by excessively low gas pressure of the gas and impure combustible gas components.
