Disconnect control method of a gas water heater

Abstract

The invention discloses an outage control method for a gas water heater. The outage control method includes: starting the gas water heater; collecting demand load data; judging whether the current demand load is stable according to the collected demand load data; if the current demand load is stable , then judge whether the gas water heater is currently out of gear; if the gas water heater is currently out of gear, then collect the demand load data again; according to the collected demand load data, judge whether the current demand load is stable; if the current demand load is stable, then Collect the current outlet water temperature of the gas water heater; compare the difference between the collected outlet water temperature value and the preset temperature value with the first preset threshold; decide whether to control the gas water heater according to the P1H state or P2L state according to the comparison result heating. The method is simple and reliable, and can effectively solve the problem of the outage of the gas water heater.

Description

Technical field [0001] The present invention relates to the field of household appliances, and more particularly to a breaking control method of a gas water heater. Background technique [0002] In the prior art, all of the gas water heaters are thermostatic gas water heaters. There are different segmented methods such as 2-4-6, which means that the water heater is burned, and 2 rows can be used. 4 row or 6 row) Fire heat combustion, select different ranks according to different loads, but when the water heater is factory factory, the maximum fire power load must be guaranteed to be larger than 4 rows, the maximum thermal power load is greater than 6 rows, the minimum fire power load , Has guaranteed load continuity. However, due to the environmental impact of the user (low gas intake pressure or low gas heat value), the maximum thermal power load of 2 rows is less than 4 rows, and when the user's demand load is in the 2 row, the maximum fire power load and the 4 row minimum fire...

AI Technical Summary

Problems solved by technology

However, due to the influence of the user's use environment (low gas intake pressure or low gas calorific value), the maximum thermal load of the second row is less than the minimum thermal load of the fourth row. When the user demand load is between the maximum thermal load of the second row and the minimum thermal load of the fourth row Time, the water heater can not reach, when the maximum load of the 2nd row, the load is not enough to switch to the minimum fire of the 4th row, when it is switched to the minimum fire of the 4th row, the load is large again, repeatedly between the maximum firepower load of the 2nd row and the minimum firepower of the 4th row switch between loads
