The wall-mounted fresh air fan with inner circulation purification function is characterized by: upper shell with upper and lower return air outlet, inner and middle fresh air chamber, electric fresh air valve, main view surface with booster box cover plate, centrifuge inside booster box cover plate, booster chamber formed between shell and booster box cover plate, high-efficiency filter net and outlet grid on the left and right sides of shell and booster box cover plate, top layer of upper and lower return air outlet. An electric return air valve is set between the return air grid and the fresh air chamber, the back of the shell is connected with the outdoor air duct and the electric fresh air valve, the back of the fresh air chamber is connected with the electric fresh air valve and the outdoor air duct, and the fresh air chamber is connected with the booster chamber. The operation procedure is divided into two operation modes: fresh air and clean air; the beneficial effect is that fresh air containing oxygen outside is purified and sent into the indoor. It can also choose to purify indoor air by circulating filtration, so that the volume of products with the same air volume can be smaller and the manufacturing cost can be reduced.
【技术实现步骤摘要】
带内循环净化功能的壁挂式新风机
本技术属于室内通风换气设备领域,具体涉及带内循环净化功能的壁挂式新风机。
技术介绍
市场上单向流壁挂式新风机普遍没有内循环净化功能,仅能往室内送入新鲜空气,当室内空气污染较严重时,不能及时处理空气中的污染物;同时,其机体积太大,不但材料成本高、人工成本也高,且安装时需要占用较大空间,影响室内感观;同时过重的机体需要高强度的墙体来支撑固定,如安装到窗户上,会带来安全隐患。
技术实现思路
本技术的带内循环净化功能的壁挂式新风机不但可以将室外含氧的新空气净化处理后送入室内,还可以循环过滤净化室内污染的空气;同时,该机通过简化风道结构设计,缩小整机体积、减轻重量,可以大幅降低成本。为了达到上述目的,本技术的带内循环净化功能的壁挂式新风机是以下述方式实现的:设壳体,壳体上层内设上下回风口,壳体内中间设新风腔、电动新风阀门,壳体主视面设增压箱盖板,增压箱盖板内设离心机,壳体内与增压箱盖板之间形成增压腔,壳体与增压箱盖板左、右侧设高效滤网、出风网栅,上下回风口顶层设回风网栅,上下回风口与新风腔之间设电动回风阀门,壳体背面连接室外风管和电动新风阀门,新 ...
