What are the advantages of an air heat pump dryer with a dehumidifying duct?

The utility model relates to an air heat pump dryer with a dehumidifying air duct, comprising a cabinet for generating central convection air and a drying oven for placing materials, which are arranged on both sides of the cabinet, and one side of the cabinet is arranged in an opening shape, a convection fan is arranged in the cabinet to generate convective air, and the upper and lower ends of the side walls of the oven on the opposite side of the cabinet are all provided with wet exhaust passages for ventilation to the outside world, accordingly, the humidity of the air in the upper and lower sidewalls of the oven is reduced, thus increasing the dryness of the air re-entering the oven and further reducing the dehumidification load in the oven, at the same time, as the dehumidifier absorbs the air from the upper and lower side wall areas of the oven, the moist air from the upper and lower side wall areas of the oven can be discharged to the outside quickly, and when the temperature in the oven or the cabinet is higher than the set value, open the dehumidifying fan to reduce the temperature of the oven or the cabinet.
