Background technology
Along with the fast development of economy, the continuous acceleration of urbanization process, car owning amount is in continuous increase per capita, and increasing tail gas is thrown in air, causes air contaminated.Simultaneously because the excess load of city and outskirts regional industry develops, environment is by pollution wantonly and destruction, and serious exacerbates outdoor air pollution phenomenon.In addition, indoor due to various finishing with newly purchase impurity, virus and pernicious gas indoor the life at home to people that furniture material etc. produces and cause pollution, thereby produce the hidden danger of health, the serious people that will cause suffer from disease.
Now for the purification of room air, the general form adopting air purifier; But air purifier only assume responsibility for the effect of indoor air purification, cannot the oxygen content in room air be supplemented.As increased indoor oxygen content, or the mode by introducing outdoor air is needed to carry out.But introducing outdoor air of directly windowing, directly will introduce outdoor contaminated air.Therefore, need to research and develop a kind of product not only can introduced with clean room's outer air but also indoor air purification circulation can be realized.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use and reliable, not only can introduce new wind but also purification of air can be realized, prevent while in air, harmful substance is polluted for indoor living space, effective dredging of indoor-outdoor air can be ensured again, guarantee the air cleaning unit for new wind and air cleaning system of room air oxygen content and security.
The object of the invention is to have come by following technical solution, a kind of air cleaning unit for new wind and air cleaning system, described new wind and air cleaning system at least comprise one and are arranged on fan assembly, elongated with windowsill under window hole, with air channel, the indoor housing of cavity passage, described air cleaning unit comprises one and is arranged on purification main frame casing below the housing of air channel, according to being separately installed with cleaning module and inner-outer circulation switching mechanism up and down in casing, and between described cleaning module and inner-outer circulation switching mechanism between be equipped with sealed inserted piece,
The indoor profile of described casing is configured with the decoration panel of band indoor air inlet, and the back side of casing offers external air inlet mouth; Described indoor air inlet and external air inlet mouth lay respectively at bottom two corresponding side surface of casing, be communicated in the inner-outer circulation switching mechanism playing unidirectional blocking indoor air inlet and the effect of external air inlet mouth in casing respectively, and be communicated with the cleaning module of top through wind passage mouth upwards by this inner-outer circulation switching mechanism, be communicated in the cavity passage of air channel, top housing after upwards drawing casing by the purification channel that cleaning module is offered.
As preferably: described inner-outer circulation switching mechanism comprises a box-like housing being arranged in casing, being connected by bottom base and upper cover plate, the air inlet docked with indoor air inlet and external air inlet mouth is respectively arranged with before and after it, described upper cover plate offers the air outlet being communicated with upper cleaning device, a screwed positioning rotating shaft is installed in described box-like housing, on it by screw thread be connected be placed between the air inlet of front and back, relative movement can realize slide inside and outside opening and closing;
The integral type box filter that described cleaning module is made up of the filter course that at least twice play different filtration is formed.
As preferably: the integral type box filter that the filter course that described cleaning module plays different filtration by three roads forms is formed, described integral type box filter comprises the box shaped base that offers purification air inlet, dismountable three road filtering layers are installed successively from top to bottom in this box shaped base, comprising: main filtration anaphylactogen, dust, pollen, the first filter screen of virus and bacterial suspension thing, the little efficient filtering layer of the micro-material of HEPA to 0.009 micron air suspended particulates of main filtration, and can effectively filter clean formaldehyde, benzene, the active carbon smell filtering layer of the common air such as dioxin and ozone peculiar smell and harmful chemicals pollutant.
The present invention is installed on the downside of lower windowsill indoor air channel structure, plays and can introduce the effect that indoor-outdoor air can play again purification of air simultaneously, effectively guarantee freshness and the security of air, create a kind of health, energy-conservation house living environment; It is simple that it has structure, easy to use and reliable, not only can introduce new wind but also can purification of air be realized, prevent while harmful substance is polluted for indoor living space in air, effective dredging of indoor-outdoor air can be ensured again, guarantee the features such as room air oxygen content and security.
