Abstract

The invention discloses a fresh air fan which mainly comprises a shell, an upper door plate, a lower door plate, a first filter, a fresh air fan body, a heat exchanger and a second filter. An exhaustair inlet, an exhaust air outlet and a fresh air inlet are formed in the shell; a fresh air outlet is formed in the upper door plate; a plastic foam shell is arranged in the shell and adopts an overall mold opening structure; multiple cavities and baffle plates are arranged in the plastic foam shell; the fresh air outlet is mainly formed by a rear hemisphere, a rear fixing cover, a front hemisphere, a front fixing cover and a front decorating cover; the shell is mainly formed by a middle frame, a left side plate, a right side plate and a top plate; side frames of the middle frame are connectedby adopting a welding manner; and the middle frame is connected with the left side plate, the right side plate and the top plate through a fastening manner. The fresh air fan provided by the invention is reasonable in structure, beneficial to improving the processing production efficiency of an existing fresh air fan and saving energy, environmentally friendly, good in air purification effect, and convenient for industrial production and large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of air purification and air conditioning, in particular to a fresh fan. Background technique [0002] With the rapid development of industry, air pollution seriously threatens people's health. Studies have shown that indoor air pollution far exceeds that of outdoors. In smoggy weather, outdoor dirty air enters the room through doors and windows. Affect people's mental state and physical health.
