Description
Technical field
The present invention relates to air purification field, the air purifier with heating function is specifically referred to.
Background technology
Air purifier is also known as " air cleaner ", air cleaner, clarifier, is to refer to adsorb, decompose or convert
Various air pollutants (generally comprise finishing pollution, bacterium, the anaphylactogen of PM2.5, dust, pollen, peculiar smell, formaldehyde etc
Deng), the household appliances of air cleanliness are effectively improved, family expenses, commercialization, industry, building are broadly divided into.
There are a variety of different technologies and medium in air purifier, enable it to provide a user the sky of cleaning and safety
Gas.Conventional air purifying process has：Adsorption technology, negative (just) ion technology, catalysis technique, photocatalyst technology, superstructure light
Mineralising technology, HEPA high efficiency filters technology, electrostatic precipitation technology etc.；Material technology mainly has：Photocatalyst, activated carbon, the pole charcoal heart
The efficient material of filter core technology, synthetic fibers, HEAP, anion generator etc..Being adopted existing air purifier to be compound, i.e., more
A variety of purification techniques and material medium are employed simultaneously, but existing empty clarifier and electric heater are separate, it is impossible to it is real again
Heated while now purifying air, function is more single, application can not be maximized by turn resulting in resource, and individually empty
Gas purifier can also take indoor more space with electric heater.
The content of the invention
It is an object of the invention to provide the air purifier with heating function, air is entered while realizing air cleaning
Row heating, to reduce the occupancy of the interior space.
The purpose of the present invention is achieved through the following technical solutions：
Air purifier with heating function, including profiling housing, the profiling housing include upper shell and and upper casing
The bolted lower house of body, base is provided with the lower house bottom, and air intake is provided with the side wall of the lower house
Mouthful, multiple through holes are provided with lower house opposite side wall, multiple and through hole homonymy aperture is provided with the side wall of upper shell, and
The multiple through holes and aperture constitute air outlet, and horizontal positioned is fixed with and curved support in the profiling enclosure interior
Body, blower fan is fixed on the inwall of profiling housing, and the blade of the blower fan is placed in supporter, and supporter is close to air outlet one
Side is provided with heat radiation rack, and heater is placed in heat radiation rack, in addition to the filter mechanism being fixed in profiling housing, the filter
Structure covers the air inlet.For the defect of existing clarifier, applicant is by the purification function of air purifier and heating work(
It can be combined with each other, to solve the problem of interior space takes excessive；In use, supporter is located at profiling housing central section, air
Entered by air inlet, air cleaning is realized after the multistage filtering of filter mechanism, and the metal material being connected with supporter is scattered
On hot frame, heater starts to heat the air after purification, passes through the rotation of blade so that the fresh air after being heated
Overflowed at air outlet, to realize to indoor heating and air cleaning, substantially reduce the occupancy of the interior space；Wherein,
The profiling housing constituted is merged with lower house by upper shell, can be made into the shape of a variety of different-styles to increase air purifier
Visual perception.Further, to reduce influence of the heater to blower fan, supporter is using the higher plastic material of thermal resistance performance
It is made, to prevent the heat produced by heater to be directly transferred to by supporter on blower fan, it is ensured that the stability of blower fan work.
Multiple heat emission holes are provided with side wall of the heat radiation rack just to air outlet.For the heat of further increase heater
The amount release uniformity, opens up multiple heat emission holes so that heat is concentrated by just to the region of air outlet on the side wall of heat radiation rack
In the range of concentrate release, and purify after air mix under the drive of blade with the heat, with realize to purify air add
Heat, the air after heating then overflows along air outlet, it is to avoid occurs heat skewness in profiling housing and causes local temperature
It is too high.
Steering head is installed in the lower house bottom, base is connected by steering head with lower house.For further raising
The use flexibility of clarifier, steering head is provided with lower house bottom so that phase can be realized between base and profiling housing
To rotating, that is, facilitate and flow direction regulation is carried out to the fresh air overflowed at air outlet, to realize room air circulation effect most
Bigization.
The filter mechanism includes the box body of both ends open, and two open ends of box body correspond to air inlet, air outlet respectively,
And along air flow direction be arranged in order in box body the prefiltering net of distribution, HEPA filter screens, activated carbon filtering layer, uviol lamp, light touch
Matchmaker's filter screen.The air entered by air inlet is first passed around after the filtering of prefiltering net, and the dust in air or particulate matter are sieved
Choosing shielding, is then absorbed by HEPA filter screens to pernicious gases such as formaldehyde in air, and activated carbon filtering layer then can be to air
In peculiar smell carry out processing absorption, air continues to be circulated in the radiation scope of uviol lamp, and uviol lamp carries out sterilization processing to it,
To reduce indoor bacteria content, while photocatalyst filtering net produces strong catalytic degradation effect in the presence of ultraviolet, will
The toxin resolution process that bacterium etc. discharges, finally ensures that the air cleaning for entering profiling enclosure interior is thorough.Pass through filtering
The Pyatyi filtration, purification of mechanism so that the final air overflowed by air outlet meets national standard, to indoor air circulation
Smoothness provides corresponding ensure.
Multiple rectangular channels being spaced apart, the rectangular channel and tray interior are provided with the box body along the flow direction of air
Connection, and to extend through corresponding rectangular channel rearmounted for the prefiltering net, HEPA filter screens, activated carbon filtering layer and photocatalyst filtering net
In in box body.Preferably, opening up multiple rectangular channels on box body, i.e., multiple filter screens are inserted in corresponding rectangular channel, with box
The processing region of multiple difference in functionalitys is formed in vivo, and in prefiltering net, HEPA filter screens, activated carbon filtering layer and photocatalyst filtering net
Filter effect decline when, directly open profiling housing, to treatment effect decline corresponding filter screen change, with guarantee
Air cleaning optimum efficiency.
The present invention compared with prior art, has the following advantages and advantages：
1st, supporter of the invention is located at profiling housing central section, and air is entered by air inlet, in the multistage mistake of filter mechanism
Air cleaning is realized after filter, and on the heat radiation rack for the metal material being connected with supporter, heater starts to the air after purification
Heated, pass through the rotation of blade so that the fresh air after being heated overflows at air outlet, to realize to indoor confession
Warm and air cleaning, substantially reduces the occupancy of the interior space；
2nd, the Pyatyi filtration, purification that the present invention passes through filter mechanism so that the final air overflowed by air outlet meets state
Family's standard, corresponding ensure is provided to indoor air circulation smoothness；
3rd, the present invention opens up multiple rectangular channels on box body, i.e., multiple filter screens are inserted in corresponding rectangular channel, with box body
The interior processing region for forming multiple difference in functionalitys, and in prefiltering net, HEPA filter screens, activated carbon filtering layer and photocatalyst filtering net
When filter effect declines, profiling housing is directly opened, the corresponding filter screen that treatment effect declines is changed, to ensure sky
Gas purifies optimum efficiency.
