Fresh air ventilator provided with by-pass door

Abstract

The invention discloses a fresh air ventilator provided with a by-pass door, and belongs to the technical field of fresh air ventilator equipment. A fresh air ventilator in the prior art is relativelylow in air exchange efficiency, is complex in structure and is complex to operate. The fresh air ventilator provided with the by-pass door comprises an air inlet tube, a filter assembly and a by-passair flue, wherein the filter assembly is mounted opposite to a tube opening of the air inlet tube; the by-pass air flue and the filter assembly are arranged side by side and communicate with the airinlet tube; the by-pass air flue is equipped with a cylindrical housing capable of sealing the by-pass air flue; and the cylindrical housing is connected with a motor. According to the fresh air ventilator disclosed by the invention, the cylindrical housing is arranged, and the motor controls rotation of the cylindrical housing, so that a by-pass channel can be timely opened or closed, outdoor airwith good quality can directly enter an air inlet, and a usage rate of the filter assembly can be reduced, and therefore, abrasion on the filter assembly is reduced, the service life of the filter assembly is effectively prolonged, and use cost is reduced.

Description

technical field [0001] The invention relates to a fresh air blower with a bypass door, belonging to the technical field of fresh air blower equipment. [0002] Background technique [0003] The known fresh air equipment sends indoors after the outdoor air is purified by a filter assembly. If the outdoor air quality is good and the air does not need to be filtered through the filter assembly, but the filter assembly continues to be in a filtering state, the service life of the filter assembly will be shortened. [0004] Chinese patent (application number 200720195818.9) discloses a new type of energy recovery fresh air ventilator with bypass, which includes a heat recovery core, a partition on each side, and the first partition and the second partition. There are fresh air inlets and fresh air outlets at the corner position, exhaust air inlets and exhaust air outlets at the other diagonal positions of the second partition and the first partition, and the first partition ...

AI Technical Summary

Problems solved by technology

This solution requires manual operation, low air exchange efficiency and the need to insert multiple wind baffles, complex structure and cumbersome operation

Furthermore, the above-mentioned technical solution cannot open or close the bypass channel in time, and when it is not opened in time, it will cause unnecessary loss of the core body; Applied to indoor air purification treatment
