[0073] Example 1: Application on household or commercial gas stoves and water heaters

[0074] When the gas cooker or water heater is in use, the time between ignition and successful ignition will arouse people's anxiety if it takes too long, and it is generally best to control it within 5 seconds.

[0075] However, in applications where there is no time requirement, in order to ensure that the hot surface igniter does not have a moderate service life, we generally use a constant voltage or constant power control method to make the igniter heat up slowly.

[0076] Combining the above, if you want the hot surface igniter to be well applied on the gas cooker or water heater, you must balance the two contradictions. Therefore, the three types of control strategies of variable voltage control, variable power control, and variable voltage plus variable power hybrid control in this embodiment can be used to ensure the service life of the hot surface igniter and shorten the ignition ...

Abstract

The invention discloses a control strategy for a hot-side igniter. Based on the hardware circuit and software algorithm of the hot-side igniter, the working time of the hot-side igniter is divided into t1, t2,...tn time periods, and each In a period of time, the output voltage or output power of the hardware circuit is adjusted through the software algorithm to make the hot surface igniter reach the expected temperature. The ignition time of the hot surface igniter can be easily controlled by the control strategy of the present invention. To meet the needs of customers who need ignition in a short time.

Description

technical field [0001] The invention relates to a control strategy, in particular to the temperature change control strategy of the hot surface igniter in the working process. Background technique [0002] Combustion equipment in regions / countries such as China usually adopts spark ignition. However, spark ignition has problems such as unreliable ignition, deflagration, and electromagnetic interference. The unreliable ignition is because spark ignition is easily affected by factors such as temperature, humidity, ignition gap, arc leakage, and pollution. Therefore, North American countries with many types of combustion equipment and more advanced combustion equipment application technology use more hot surface ignition technology. After the hot surface igniter reaches a high temperature in advance, the combustible gas / fuel oil enters the combustion area again, completely avoiding electric shock. Possible problems with sparks. [0003] The hot side igniter is factory-set wi...
