Gas water heater ignition self-detecting control system and method

Abstract

The invention provides a gas water heater ignition self-detecting control system and method. The gas water heater ignition self-detecting control system comprises a main controller, a direct current speed adjusting fan, a fan control circuit, a rotating speed feedback circuit, a current feedback circuit and an ignition mechanism. The control end of the main controller is connected with the ignition mechanism and connected with the input end of the fan control circuit. The output end of the fan control circuit is connected with the input end of the direct current speed adjusting fan. The inputend of the main controller is connected with the output end of the rotating speed feedback circuit and the output end of the current feedback circuit. The input end of the rotating speed feedback circuit and the input end of the current feedback circuit are connected with the output end of the direct current speed adjusting fan. According to the technical scheme, whether blocking occurs or not canbe detected fast, meanwhile, the wind pressure resisting performance is improved, and normal safe use of users can be ensured.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to an ignition self-check control system and method for a gas water heater. Background technique [0002] In the traditional technology, when the gas water heater is ignited, an ignition wind speed and an ignition load are set according to the actual combustion conditions of the fire row and taking into account the success rate of ignition. However, in special environments, such as the northwestern region with large indoor and outdoor temperature difference, the cold and windy eastern coastal region, and some high-rise air outlet environments, due to the high external wind speed, the ignition load and ignition wind speed of the gas water heater are fixed each time, so the There will be wind blockage, which will cause the gas water heater to fail to ignite. Not only will it produce exhaust gas, but what is more frightening is that deflagration may occur, which not only affe...

Problems solved by technology

However, in special environments, such as the northwestern region with large indoor and outdoor temperature difference, the cold and windy eastern coastal region, and some high-rise air outlet environments, due to the high external wind speed, the ignition load and ignition wind speed of the gas water heater are fixed each time, so the There will be wind blockage, which will cause the gas water heater to fail to ignite. Not only will it produce exhaust gas, but what is more frightening is that deflagration may occur, which not only affects the normal use of the user, but also has a very adverse impact on the safety of the user.
