Problems solved by technology
[0004] However, due to the hysteresis of the heat load change, the change of the flame height, the change of the exhaust air volume and the waste heat of the heat exchanger, after the burner is switched in stages, the outlet water temperature will suddenly rise within a certain period of time. Or lower the situation, resulting in large temperature fluctuations, resulting in lack of product performance

The present application relates to a burner section switching control method and device for heating equipment and heating equipment. The method includes: obtaining the current heat load of the heating equipment under normal operation status and the current environment data. When it is determined according to the current heat load and the current environmental data that the working mode switching condition of the burner of the heating equipment is met, the burner of the heating equipment is controlled to switch in stages, and the heat load correction mechanism is triggered, and the combustion is reduced according to the heat load correction mechanism. The heat load variation fluctuates when the controller performs segment switching. This method realizes the correction mechanism according to the heat load, reduces the fluctuation of the heat load variation after the segmental switching of the gas water heater when the gas water heater is burning, reduces the fluctuation range of the water temperature after the segmental switching, and avoids the sudden rise and fall of the water temperature. Thereby improving the product performance and use comfort of the heating equipment.
Description
technical field [0001] The present application relates to the technical field of electric appliance control, in particular to a burner stage switching control method and device for heating equipment and heating equipment. Background technique [0002] With the development of electrical control technology and the wide application of various electrical equipment in people's work and life, the requirements for the product performance of electrical equipment in the actual use process are increasing day by day. Commonly used electrical equipment includes heating equipment such as gas water heaters. In actual use, for different use times, such as summer and winter, in order to meet the actual needs of users, the set temperature rise should be different. [0003] Traditionally, the combustion technology of multi-stage fire row switching in stages is mostly used to control the degree of temperature rise. When the user is using the gas water heater, if the current required heat load...
