Title:
AIR SUPPLY ASSEMBLY AND LAUNDRY TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/142252
Kind Code:
A1
Abstract:
An air supply assembly and a laundry treatment device. The air supply assembly comprises an air duct and a filter member guide rail, wherein the air duct comprises an air inlet and an air outlet; at least part of the filter member guide rail extends into the air duct; the filter member guide rail is located between the air inlet and the air outlet; and the filter member guide rail comprises a bent portion located in the air duct. The bent portion is formed in the portion of the filter member guide rail that extends into the air duct, such that a filter member inserted into the filter member guide rail is deformed therewith and is bent. Since, under the same air duct size, the effective length of a curve is greater than the length of a straight line, the filter member can trap more lint, and the same amount of lint is spread over more areas, resulting in a smaller air resistance and smaller air volume loss, which is conducive to improving the efficiency of heat exchange between the air flow and a downstream heat exchanger, thereby improving the laundry drying effect.
