AI Technical Summary

Technical Problem

Existing dryers or dryer combos have low drying efficiency, resulting in excessively long drying times. This is mainly because the high-temperature airflow inside the drum contains too much moisture, which affects the drying efficiency of clothes.

Method used

A moisture absorption and dehumidification module, including a regenerating shell and a disc, is added to the dryer or dryer-dryer combo. The disc absorbs moisture from the humid airflow in the dehumidification zone and releases the moisture under the action of the heating element, generating a low-temperature dry airflow to improve the dryness of the airflow. The absorbed moisture is then regenerated into humid airflow in the desorption zone by the heating element, and the airflow is recycled to improve the drying efficiency.

Benefits of technology

It effectively reduces the moisture content of the drying airflow inside the drum, shortens the drying time, improves the drying efficiency of clothing processing equipment, and reduces drying time by 10%-30%.

Abstract

A drying apparatus and a clothes treatment device. The drying apparatus (4) comprises a moisture absorption and dehumidification module (41), a heat pump module, a heating assembly (44), and a cooler (7), wherein the moisture absorption and dehumidification module (41) has a dehumidification area (4112) and a desorption area (4113); the heat pump module comprises an evaporator (5) and a condenser (6); and in an airflow direction, the evaporator (5), the dehumidification area (4112) of the moisture absorption and dehumidification module (41) and the condenser (6) are sequentially connected, and the desorption area (4113) of the moisture absorption and dehumidification module (41), the condenser (6), and the heating assembly (44) are sequentially connected to form a circulation loop. The drying apparatus can reduce moisture of drying airflow, and improve the drying efficiency of the clothes treatment device, thereby reducing drying time.
