High-quality materials: use high temperature resistant flame retardant materials, built-in microcomputer protection program, automatic two modes after 3 hours: switch to cold air mode, with overheating temperature control protection system, protection circuit. Heating technology: using ceramic heating technology, its thermal efficiency is much higher than ordinary heating technology such as hot wire, it has mild heat dissipation, low power, high thermal efficiency, and the clothes are not damaged. Humanized design: One-button operation, open/close, change cold/hot air, easy to operate, when the red light is on, the machine works normally, outputs warm air, and quickly dries clothes. Three hours after the warm air mode, the blue light is on, and the machine automatically enters the cold air drying state and automatically shuts down.
