Drying module and washing and drying integrated machine

Abstract

A drying module and a washing and drying integrated machine. A wet circulating air flow from a drum is conveyed by means of a circulation module to a dehumidification module for drying, and the dehumidification module adsorbs moisture from the wet circulating air flow from the drum, such that a dry circulating air flow is outputted to the drum. A regeneration module enables a dry regenerated air flow to be outputted to the dehumidification module so that at least a part of the dehumidification module desorbs moisture and regains a moisture adsorption capacity. A condensation module is used for condensing the regenerated air flow, which is outputted by the regeneration module, so as to form a low-temperature dry regenerated air flow. Condensate water formed during condensation is discharged. The dehumidification module, the circulation module and the condensation module are modules independent of each other.
