AI Technical Summary

Technical Problem

Existing ducted air conditioners suffer from problems such as hot air rising and being difficult to deliver to human activity areas in heating mode, and cold air blowing directly on people in cooling mode, resulting in poor comfort. They also have issues with baffle interference and small return air duct cross-section during the volute rotation process.

Method used

It adopts a sliding inner baffle and a drive mechanism. The drive mechanism synchronously drives the rotation and sliding of the volute and the inner baffle to switch the air outlet state of the volute and adjust the air guide channel and return air area of ​​the longitudinal air outlet in different modes.

Benefits of technology

It improves the air supply and return performance and user comfort of the ducted air conditioner under different operating conditions, reduces the risk of interference between the volute and the baffle, and reduces the restrictions on the size and profile design of the volute.

Abstract

The application relates to the field of air conditioning equipment, in particular to an indoor ducted air conditioner. The indoor ducted air conditioner comprises a casing, an inner baffle, an outer baffle, a volute and a driving mechanism. In the process that the volute rotates from a first air outlet state to a second air outlet state, the driving mechanism is configured to drive the inner baffle to gradually move away from the outer baffle. In the process that the volute rotates from the second air outlet state to the first air outlet state, the driving mechanism is configured to drive the inner baffle to gradually move close to the outer baffle. By setting the baffle close to the heat exchange cavity as a slidable inner baffle and synchronously adjusting the position of the inner baffle in the process of switching the two air outlet states of the volute, the longitudinal air outlet can form a more suitable air guide channel when used as an air outlet, and can release a larger flow area when used as an air inlet, so that the air guide demand of the lower air outlet and the large-section return air demand are simultaneously considered. The structure is also beneficial to reducing the interference risk between the volute and the baffle and reducing the limitation on the size design of the volute.
