Abstract

The invention relates to a fresh air ventilator with an indoor air self-purifying function. The fresh air ventilator comprises a machine enclosure as well as a fresh air fan, an air return fan, a heat exchanger and a filter which are mounted in the machine enclosure, wherein an upper air return control valve is mounted between an air return channel and a fresh air channel; after the upper air return control valve is opened, returned air does not enter the heat exchanger any more, but enters the fresh air channel, is discharged into a room through a filter, the fresh air fan and a fresh air discharge tube in sequence along a path of fresh air, so that self-circulating of indoor air is realized.

Description

technical field [0001] The invention belongs to the field of air purification, and relates to a fresh air blower, in particular to a fresh air blower with the self-purification function of indoor wind. Background technique [0002] The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. , so that the room is fresh and clean air all the time. [0003] However, in the case of poor outdoor air conditions, such as severe smog, it is not suitable to introduce fresh air, and indoor air purifiers are more suitable for use. How to make the fresh air blower have the function of indoor air self-circulation is the technical problem to be solved in the present invention. Contents of the invention [0004] The purpose of the present invention is to overco...
