US 2024/0407585 A1 · HEATING CONTROL CIRCUIT AND HEATING EQUIPMENT

Abstract

Disclosed are a heating control circuit and a heating equipment. The control module is respectively connected with the zero-crossing detection circuit, the thyristor switch circuit and the temperature control circuit. The time is preset in the control module. If the heating control circuit is powered off, it will be powered on again within the preset time as the signal collected by the zero-crossing detection circuit triggers the conduction of the thyristor switch circuit to start the heating component, and resume the heat preservation mode, by which the body memory function is implemented; even if the heating control circuit is not powered on again within the preset time after the heating control circuit is powered off, the water temperature is detected through the temperature control circuit to realize the water temperature memory function.
