Description
Technical field
The utility model is related to a kind of indoor environment purifier, more particularly to a kind of fresh air purifier.
Background technology
Existing fresh air purifier, as shown in Figure 1, mainly by low efficient filter, pressure fan, exhaust blower, medium effeciency filter,
The compositions such as high efficiency particulate air filter, active carbon module, babinet, air port.But pressure fan is arranged in fresh air outlet side.
The pressure fan of fresh air purifier needs to overcome the resistance of Air to air ERV device, cleaning module etc., air-supply
Machine need to have the features such as small flow, high-head, low noise, in addition size limitation this wind turbine general choice at present is small straight
The outlet high frequency noise of diameter, high-revolving centrifugal blower, this kind of wind turbine is bigger.Since pressure fan is arranged in fresh air outlet more
Side causes pressure fan outlet high-frequency noise to be passed directly to interior, and room noise is exceeded, in order to solve the problems, such as room noise, now
The way of use is to add static pressure sound attenuator or silencing pipeline to reduce noise in exit, to meet room noise requirement.In this way
Later stage installation difficulty can be increased, while silencing means needs and wind turbine matches could meet noise specification.
In addition, existing fresh air purifier due to pressure field of the cleaning module at fan inlet side, cleaning module and
Velocity field is unevenly distributed, it is excessive or too small there are local velocity the problems such as, and then the different section of cleaning module is caused to use
Efficiency is different, service life is inconsistent, influences the service life and purification efficiency of cleaning module.
Invention content
The purpose of this utility model is exactly in order to overcome the above-mentioned deficiencies of the prior art, to provide a kind of fresh air purifier, energy
The outlet noise for effectively reducing fresh air purifier, extends the service life of cleaning module, improves the purification efficiency of cleaning module.
The purpose of this utility model is achieved by the following technical measures：A kind of fresh air purifier, including it is babinet, new
Wind inlet, fresh air outlet, air draft import, wind exhausting outlet, exhaust blower, Air to air ERV device, low efficient filter, medium air filtration
Device, high efficiency particulate air filter, active carbon module, flow-harmonization device, pressure fan, outdoor air enter from fresh inlet, were slightly imitated through second
Enter pressure fan after filter, Air to air ERV device, pressure fan outlet air is through flow-harmonization device, medium effeciency filter, activated carbon
It after module, high efficiency particulate air filter, exports and sends out from fresh air, indoor gas enters from air draft import, through the first low efficient filter, air
After energy recycle device, it is discharged from wind exhausting outlet by exhaust blower.
In the above-mentioned technical solutions, the flow-harmonization device is made of four layers of orifice plate, and adjacent orifice plate position of opening is different,
Trepanning interlaced arrangement.
In the above-mentioned technical solutions, one layer of orifice plate silencing means is arranged on the cabinet wall of pressure fan periphery.
The utility model fresh air purifier, it is simple in structure, easy to use, it can effectively extend filter service life, improve
Purification efficiency, while outlet noise is reduced, indoor environment comfort is improved, later stage installation and debugging difficulty is reduced.
