AIR-CONDITIONER AIR SUPPLY APPARATUS IN VERTICAL AIR-CONDITIONER

摘要

An air-conditioner air supply apparatus (1) in a vertical air-conditioner is disclosed, including at least three annular air guiding bodies (11, 13, 17, 12) that are hollow and each have front and rear openings, where each annular air guiding body (11, 13, 17, 12) is a single component, a rear opening of the annular air guiding body (11, 13, 17, 12) is an air inlet, a front opening thereof is an air outlet, multiple annular air guiding bodies (11, 13, 17, 12) are arranged sequentially from front to rear, a through-duct running from front to rear is formed in the middle, an annular heat-exchanged air duct (14, 15, 18) is formed between two adjacent annular air guiding bodies (11, 13, 17, 12), an air inlet of a rear-end annular air guiding body (12) located at the rear end is a non-heat-exchanged air inlet (122), an air outlet of a front-end annular air guiding body (11) located at the front end is a mixed air outlet (111), and multiple annular heat-exchanged air ducts (14, 15, 18) are gradually reduced in volume in a direction from the non-heat-exchanged air inlet (122) to the mixed air outlet (111). Applying the air supply apparatus (1) in the air-conditioner not only can increase an air inlet volume of the air-conditioner and improve mildness of the air exhausted from the air-conditioner, but also is beneficial to uniform circumferential air exhausting of the heat-exchanged air duct (14, 15, 18) and can reduce pressure loss and noise.
