Abstract

The invention discloses a fresh air machine with a multi-duct switching structure. The fresh air machine comprises a housing, the housing is provided with an equipment air inlet, an equipment air outlet, an indoor air inlet and an indoor air outlet, a circulating duct with a circulating fan is arranged in the housing, the four air inlets and air outlets are connected with the circulating duct, andair valves are arranged on the equipment air inlet, the indoor air inlet and the indoor air outlet; the air inlet of a three-way pipe is connected with the equipment air outlet, two air outlets of the three-way pipe are connected with indoor space and outdoor space through pipelines, and a switching structure which is used for switching the two air outlets is arranged on the three-way pipe. The fresh air machine has the advantages that a duct switching method based on the fresh air machine is characterized in that functions of air refreshing, discharging and heating of the method is driven through a fan through the switching of the air valves or the switching device, the cost and complicity of the equipment are greatly reduced, and the occupation of the installing space is reduced.

Description

technical field [0001] The invention relates to the field of residential fresh air systems, in particular to a fresh air fan with a multi-air duct switching structure and an air duct switching method. Background technique [0002] As a device that can introduce fresh outdoor air into the room and discharge indoor dirty air, the fresh fan can effectively reduce the indoor carbon dioxide concentration, formaldehyde, aromatic benzene and other harmful gases, increase the oxygen content, and prevent air conditioning diseases. At the same time, an air filter is generally built into the fresh air fan, through which bacteria, particulate matter (PM2.5) and other harmful substances in the fresh air are filtered to ensure the cleanliness of the fresh air introduced into the room. [0003] In the prior art, fresh air fans newly installed or refitted in residential buildings often have a single function, and can only solve the functions of air supply and exhaust indoors. When installin...
