AI Technical Summary

Technical Problem

The condenser duct design of existing washer-dryer combos makes it easy for lint to adhere, affecting drying efficiency. Furthermore, existing lint removal solutions cannot simultaneously guarantee drying performance and duct cleanliness.

Method used

The S-shaped condenser duct, combined with the centrifugal force at the sharp bend, separates moisture and lint from the circulating air. Effective separation is achieved through the design of the air guide channel and baffle. In conjunction with the spray device to clean the filter section, the cleanliness of the circulating air is ensured.

Benefits of technology

It improves drying efficiency and user experience, reduces the residence time of lint and condensate in the air duct, ensures dry and clean circulating air, and simplifies the maintenance process.

Abstract

The application discloses a washing and drying integrated machine and a condensing air duct thereof. The condensing air duct comprises an air duct body arranged at the rear part of an outer cylinder and a condensing device arranged in the air duct body and separating the air duct body into a first chamber and a second chamber. The air outlet and the air inlet of the air duct body are respectively located in the first chamber and the second chamber. The condensing device is a wind path with an S-shaped structure. The bending part of the wind path is an acute angle. The first chamber and the second chamber are communicated through the wind path. The circulating air is subjected to a large centrifugal force when passing through the bending part. The condensing water and lint mixed in the circulating air can be thrown out under the action of the centrifugal force, so that the separation of the circulating air, the condensing water and the lint is realized. A filtering part is arranged at the rear side of the wind path, so that the circulating air flowing out of the wind path can be filtered again, and the cleanliness and dryness of the circulating air are improved. The lint and the condensing water attached to the filtering part can fall off from the filtering part under the spraying of a spraying device, so that the cleaning of the filtering part is realized.
