Description

Technical Field

[0001] The utility model belongs to the technical field of gas equipment, and in particular relates to a novel gas ignition integrated heating controller. Background Art

[0002] Heaters are mainly devices that use fuel oil as fuel to generate heat and are used to keep warm. The heaters are light, flexible, small, light, powerful, easy to operate, safe and reliable, and use less electricity and fuel. Heaters are divided into two types: industrial and household. The most common are in the industrial field. In the industrial field, they are mainly used to heat some industrial and commercial places and some large spaces such as buildings and bridges. They can also be used for heating livestock in cold areas.

[0003] Traditional coal-fired heating, common electric heating, and emerging oil heating. Among various heating methods, air heating is relatively comfortable. Oil heating, as an emerging air heating method in the industry, can also provide clean and dry hot air to heat the entire space with uniform temperature. It has the advantages of rapid heating and fast heat flow. However, this kind of storage for a long time will cause the diesel to deteriorate, or the entry of impurities will cause incomplete combustion and a lot of smoke. In addition, the controller and igniter on the market are separate accessories with relatively high cost.
