Gas water heater constant temperature control method

Abstract

The invention discloses a gas water heater constant temperature control method which comprises the following steps: starting a gas water heater; collecting a plurality of water flow data; according tothe collected water flow data, judging whether the current water flow has circulating fluctuation; if yes, calculating the average value of a plurality of groups of water flow data to obtain the current demanded load; controlling the gas water heater to heat according to the current demanded load obtained through calculation; collecting a plurality of groups of flow data once more; and accordingto the collected water flow data, judging whether the current water flow is stable. The gas water heater constant temperature control method is simple and reliable, so that the gas water heater can ensure that the water outlet temperature is relatively constant when the water flow has circulating fluctuation.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a constant temperature control method of a gas water heater. Background technique [0002] In the prior art, most gas water heaters are constant-temperature gas water heaters, and water heaters with different loads have different segmentation methods, such as 2-4-6 segmented gas water heaters, which means that when the water heater is burning, it can use 2 rows of fire ( 4 rows of fire or 6 rows of fire) for heating and burning, and choose different rows for combustion according to different loads, but when the water heater leaves the factory, it must be ensured that the maximum firepower load of 2 rows is greater than the minimum firepower load of 4 rows, and the maximum firepower load of 4 rows is greater than the minimum firepower of 6 rows Load, load continuity has been guaranteed. However, due to the influence of the user's environment (when the water pressure ...

AI Technical Summary

Problems solved by technology

However, due to the influence of the user's environment (when the water pressure is unstable, the water flow fluctuates greatly), the demand load will be greater than the maximum fire of the 2nd row when the water flow is at a high point, and it is necessary to switch to the 4th row of fire, and the water flow is at a low point. , the demand load is less than the minimum fire of the 4th row, and it is necessary to switch to the 2nd row of fire, so that the gas water heater will shift gears back and forth, and the flame will be unstable, which will lead to the sudden increase and decrease of the outlet water temperature
