Carbon oxide detecting linkage control system and control method

Abstract

The invention discloses a carbon oxide detecting linkage control system and a control method. The system comprises an air inlet adjusting device, a carbon oxide detector and a main controller. The airinlet adjusting device comprises a cover plate, a slide rail and a slide driving mechanism. The cover plate slides along the slide rail under the action of the driving of the slide driving mechanism.The carbon oxide detector is connected with the slide driving mechanism and the main controller. The method includes the steps of receiving the CO content value detected by the carbon oxide detectorwhen a gas water heater works, comparing the received CO content value with a standard value range, and controlling the size of an air inlet according to a comparison result. By means of the system and the method, the linkage control over a variable air supplementing structure and the carbon oxide detector is realized, by detecting the CO content and judging whether the air and gas supplementing ratio meets the optimal mixing state or not under different states, the inlet amount of air participating in combustion is regulated to be more precise, surplus air brings a lower ratio of heat, and meanwhile the CO content is more stably controlled.

Description

technical field [0001] The invention relates to a sliding drive structure and gas detection and control technology, in particular to a carbon monoxide detection linkage control system and control method. Background technique [0002] For consumers, the safety and environmental protection of gas water heaters are extremely important indicators. The impact of gas water heaters on the market on safety and environmental protection is mainly reflected in the relatively vague control of the mixing ratio of gas and air when the water heater is burning, and uneven mixing of gas and air. , Carbon monoxide and nitride emissions cannot be well controlled, wasting gas. [0003] The main reason for the above is that when the gas water heater is burning, it mainly adjusts the supply ratio of gas and air by adjusting the air flow of the fan, while only part of the fire row burns during segmental combustion, and the size of the air inlet remains unchanged, resulting in no matter what Adjus...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a carbon monoxide detection linkage control system and control method, which solves the problem that the excess air supply takes away the heat of the combustion flame and the insufficient air supply to control the total air flow, resulting in excessive carbon monoxide.
