Abstract

This invention is centrifuge type fan and fresh air device with indoor air purifying function. The centrifuge type fan includes wind wheel; wind channel on external part of wind wheel; engine driving the wind wheel. The said wind channel is the cavity formed by two wind channel boards, front side board, back side board and external surface of wind wheel. The front and back side boards connect to both sides of two wing channel boards. Both ends of wind channel have an air current outlet opening. Thus, they form double wind channels with double outlet openings. The absorbed air current is discharged to two directions at same time through two wind channels and two air outlet openings. The fresh air device includes machine case; centrifuge type fan group combined by two centrifuge type fans; air filtrating element; front board for control and display. This invention increases working efficiency. It also reduces noise and energy loss.

Description

【Technical field】

[0001] The present invention relates to a centrifugal fan, in particular to a centrifugal fan which is matched with two independent air passages and two air outlets by a centrifugal wind wheel to form a simultaneous reverse air outlet, and a centrifugal fan made of this centrifugal fan with Fresh air device with indoor air purification function. 【Background technique】

[0002] People widely use air conditioners, ventilators, fans and other air-conditioning and air-driven devices or equipment in daily life, and these devices tend to be more and more miniaturized. Among various forms of air supply devices, centrifugal fans are widely used due to their compact structure, small size, large air pressure, and long air supply distance.

[0003] The structure of the known centrifugal fan is shown in Figure 1. It is provided with a long volute on the outside of the wind wheel. This kind of long volute is used to accelerate and guide the airflow, so as to increase ...
