Problems solved by technology

[0002] Currently commercially available gas water heaters generally include a control system and a driving triode, and a solenoid valve is provided on the gas channel A. Then output the above signal to the solenoid valve. During the ignition period, the solenoid valve is in the open state, the gas is unblocked, and the gas volume in the combustion chamber is large. Large enough to damage the water heater, and there are unsafe factors

Embodiment

[0009] The schematic diagram of the present invention is as figure 1 As shown, it includes the control system and the driving triode. There is a solenoid valve on the gas channel A. During the ignition period, the control system outputs a pulse signal to the driving triode, and the driving triode then outputs the above signal to the solenoid valve, so that the solenoid valve can be turned on and off. The cycle action between shut-off makes the gas channel A in the cycle state of on and off, and reduces the amount of gas in the combustion chamber before ignition. After the ignition, the control system outputs a single open signal, and the gas channel A is on. state, so that the water heater can work normally.

[0010] The method used in this embodiment is: within 0-8 seconds of ignition, the control system outputs a series of pulse signals, so that the solenoid valve is opened for 100-250 milliseconds, closed for 100-250 milliseconds, and the cycle is activated. After ignition,...

Abstract

The control method of gas dose in combustion chamber in lighting stage of gas wter-heater includes control system, drive triode and electromagnetic valve mounted on the gas pipe. The control system outputs the signal to drive triode, then the signal can be transferred into electromagnetic valve by means of the drive triode. In the lighting period, the signal outputted by control system is pulse signal so as to make the electromagnetic valve circularly act between opening and closing and make the gas channel be in opening and closing circulation state, so that the gas consumption dose before lighting can be reduced, after it is lighted, the signal outputted by control system is an opening signal, the gas channel is in opening state, the water-heater can be worked normally.

Description

1. Technical field: [0001] The invention relates to a method for controlling the amount of gas in a combustion chamber of a gas water heater during the ignition stage, and belongs to an innovative technology of the method for controlling the amount of gas in the combustion chamber during the ignition stage of the gas water heater. 2. Background technology: [0002] Currently commercially available gas water heaters generally include a control system and a driving triode, and a solenoid valve is provided on the gas channel A. Then output the above signal to the solenoid valve. During the ignition period, the solenoid valve is in the open state, the gas is unblocked, and the gas volume in the combustion chamber is large. Large enough to damage the water heater, and there are unsafe factors. 3. Contents of the invention: [0003] The object of the present invention is to overcome the above disadvantages and provide a method for controlling the amount of gas in the combustion...
