The invention relates to a safety voltage barbecue oven which comprises an electric heating tube. The barbecue oven further comprises a step-down transformer, a power transformer, a first rectifier, a second rectifier and a power interface. The power interface is used for connecting a power grid. The alternating-current side of the first rectifier is connected with the power interface, the direct-current side is connected with the direct-current side of an inverter circuit, the alternating-current side of the inverter circuit is connected with the primary side of the step-down transformer, and the secondary side of the step-down transformer is connected with the electric heating tube; and a starting switch is arranged on a line, connected with the power interface, of the alternating-current side of the first rectifier, and the starting switch can control disconnection between the power interface and the first rectifier after set duration after power failure. According to the technical scheme, low-voltage alternating current is adopted for supplying power to the electric heating tube, so that the probability that the electric heating tube is damaged by high-voltage electricity is reduced, and the safety of the barbecue oven is improved. When power failure occurs, the starting switch is controlled to cut off the barbecue oven after a set duration, so that the use convenience and the safety of the barbecue oven are improved.
Description
technical field [0001] The invention relates to the field of power supply control of barbecue ovens, in particular to a safe voltage barbecue oven. Background technique [0002] A grill is a common cookware used for barbecue cooking. Traditional barbecues use charcoal as fuel, but with the increasing environmental problems, many places, especially cities, have banned the use of coal as barbecue fuel, so electric barbecues have been born. [0003] An electric heating tube is arranged in the electric grill, and when the electric heating tube is powered on, heat is generated, and the user can use the heat to grill food. During use, if there is a power failure, the electric heating tube will stop working, and it will continue to work when the power is turned on again. If there is no one around to watch when the power is turned on, it may cause accidents such as fire and explosion, and there is a great potential safety hazard.
