AI Technical Summary

Technical Problem

Conventional integrated washing and drying machines face issues with increased structural size and airflow obstruction due to the arrangement of the moisture-absorbing plate and drive mechanism, which affects moisture absorption efficiency and airflow uniformity.

Method used

A drying module with a moisture-absorbing rotary wheel assembly driven by a rotary wheel drive mechanism positioned on its outer periphery, allowing for a flatter structure and uniform airflow, reducing the axial size and thickness of the washer-dryer combination washing machines.

Benefits of technology

The solution enables a more compact design with improved airflow distribution, enhancing moisture absorption efficiency and reducing the overall height or thickness of the integrated washing and drying machines.

Abstract

This application discloses a drying module and a combined washer-dryer, belonging to the technical field of household electrical appliances. The drying module (D) includes a moisture absorbing and dehumidifying member (D1), the moisture absorbing and dehumidifying member (D1) including a moisture absorbing wheel assembly (D11), a wheel housing (D12), and a wheel drive mechanism (D13) used to drive the moisture absorbing wheel assembly (D11) to rotate. The moisture absorbing wheel assembly (D11) is rotatably mounted in the wheel housing (D12). The moisture absorbing wheel assembly (D11) includes an outer circumferential housing member (D112), and the outer circumferential housing member (D11) is provided with a power input member (D114) at its outer circumferential edge for inputting power from the wheel drive mechanism (D13) to rotate the moisture absorbing wheel assembly (D11). The power input member (D114) is driven by the wheel drive mechanism (D13) at its outer circumferential edge. This application contributes to reducing the overall height or thickness of a combined washer-dryer washing machine, and because there is no transmission structure in the central area of ​​the rotary table that obstructs the flow of air, the airflow can be guided to flow more evenly around the rotary table.
