Abstract

A gas-air proportion technology contains electric controller, water flow sensor, burner, heat-exchanger, smoke exhauster, combustion chamber, switch solenoid valve, casing, cold water temperature sensor in water inlet of water heater, hot water temperature sensor in water outlet of water heater, fan, proportional valve, plural sectional solenoid valves. The rotation speed of fan is automatically adjusted synchronously according to open size of proportional valve, which is proportional to heating power of burner. The heating power W= Q#-[1] x (T1-T2)K x K1 x eta, wherein the Q#-[1] is present water flow detected by water flow sensor, T1 is hot water temperature set by hot water temperature sensor, T2 is cold water temperature set by cold water temperature sensor, K is conversion coefficient, K1 is adjusting coefficient, eta is heat efficiency.

Description

1. Technical field: [0001] The invention is a household gas instant water heater capable of adjusting the gas-air ratio, which belongs to the transformation technology of the gas water heater. 2. Background technology: [0002] Existing gas instant water heaters require primary air and secondary air for combustion of gas. The primary air enters the burner through the injector tube of the burner and is premixed with the gas before burning at the burner port. When the gas burns at the burner port, it needs Sufficient secondary air can be used for full combustion. However, there are two methods of supplementing secondary air for existing burners: natural induced draft type and blast type. Too narrow for larger loads. The blower of blast combustion is divided into several speeds to meet the air required for combustion, but it cannot be tracked linearly. Changes or fluctuations in gas pressure can lead to flame separation, misfiring, backfiring or flameout. For this reason, th...
