This invention provides an infrared defrosting device, comprising a housing, an inner liner, an infrared heater, a fan, and a flow guide. The inner liner contains a heating zone for placing the item to be heated and a heat source zone equipped with the infrared heater. The infrared heater's irradiation direction faces the heating zone. The fan generates airflow from the heat source zone to the heating zone. The flow guide alters the direction of the airflow generated by the fan as it passes the infrared heater, making it non-parallel to the irradiation direction of the heater. This design, through fan-driven airflow circulation, delivers high-temperature air from the heat source zone to the heating zone, accelerating heat exchange on the surface of the item. Simultaneously, it prevents the fan from obstructing the infrared heater and allows infrared radiation and airflow to heat different surfaces of the item separately, resulting in staggered coverage areas and preventing localized overheating or underheating of the item.
