A kind of air cleaner
Technical field
The present invention relates to a kind of air cleaner, specifically relate to a kind of air cleaner of controlling the disinfection by ultraviolet light time.
Background technology
Air cleaner can be applicable to central air conditioner system, but also stand-alone application in indoor air purification.
Air cleaner produces negative pressure by the high speed rotating centrifuge in body, with the air suction body of dirt, dirty air is removed airborne harmful gas through new and high technologies such as HEPA high density filter net and catalytic activated carbons.Anion generator discharges the air vitamin of an amount of concentration.Clean fresh air after will purifying is at last sent from the air port, is released in the interior space, thereby has reached the function that purifies air.
At present, the air cleaner on the market generally all is the effect of only filtering with fresh air, does not have sterilizing function, or sterilizing function is arranged but Burdick lamp is worked always, and the long cleaned air passes that causes of ultraviolet irradiation time has abnormal flavour and waste electric energy.If for using in central air conditioner system and not having sterilizing function at the air cleaner that special occasions such as hospital use then can not provide the air that meets sanitary standard fully as environment, this just need have a kind of air cleaner that possesses sterilizing function.
According to present technology, ultraviolet is the comparatively desirable mode that air is carried out disinfection, but ultraviolet can produce certain stink, the abnormal smells from the patient that influence purifies air.There is statistical data to show, adopt the ultraviolet irradiation intensity of 30000mW/cm2, the virus killing time of common several bacterial viruses generally only needs in 1 second, have only algae bacterioid cyanobacterium sterilizing time to need 10-40 second, in the air in the common bacteria human excrement fungus sterilizing time of mycotic spore apoplexy due to endogenous wind the longest, need 8 seconds.According to ultraviolet can uperization characteristics, can take in short-term discontinuity to open Burdick lamp, can reach in conjunction with the purification function of anion generator and can play sterilization and can play the treatment effect that purifies air again.
And air cleaner structure more complicated in the market, the parts inconvenience is changed in disassembly, cleaning.
Summary of the invention
The present invention is intended to propose a kind of air cleaner of being convenient to dismantle and can control the disinfection by ultraviolet light time.
The present invention is sterilizing equipment decontaminating apparatus with high density filter net and photocatalytic active carbon filtered air, with the Burdick lamp, adsorbs small air particles, purifies air with anion generator with high-pressure electrostatic, realizes air circulation with the high speed rotating centrifuge.
Air cleaner of the present invention comprises loam cake 1, shell 2, fan 3, motor 4, lower cover 5, anion generator and control circuit board 6, door 7, drainage screen 8, disinfection by ultraviolet light net 9, high-pressure electrostatic absorption net 10.Lower cover 5 is at lowest part, motor 4 and anion generator and control circuit board 6 are embedded in the lower cover 5, fan 3 is installed above the motor 4, shell 2 and door 7 are installed above the lower cover 5, turn left from the right side drainage screen 8, disinfection by ultraviolet light net 9, high-pressure electrostatic absorption net 10 and fan 3 are installed successively in shell 2 and door 7 inside, loam cake 1 is installed in shell 2 with above the door 7.
Door 7 and shell 2 are hinged, and pin joint is in the right back of machine.Door 7 right flank right parts have air inlet array 11, and the front side left part has venthole array 12.Shell 2 and door 7 general outline are big fillet of two plane therebetween, the two population structure size is just the same, different is to have offered air inlet array 11 and venthole array 12 above the door 7, and the two can adopt same material and with a kind of processing technique, simplify manufacture process.
The break-make control section of Burdick lamp comprises alternating current power supply 13, main switch 14, working time relay 15, intermittent time relay 16, Burdick lamp 17, working time relay normally-closed contact 18, working time relay normally open contact 19, intermittent time relay normally-closed contact 20.The total arrangement of circuit: working time relay 15 and 20 series connection of intermittent time relay normally-closed contact form loop one, intermittent time relay 16 and 19 series connection of working time relay normally open contact form loop two, Burdick lamp 17 and 18 series connection of working time relay normally-closed contact form loop three, loop one, loop two and three formation work in parallel loops, loop, alternating current power supply 13, main switch 14 and work loop are sequentially connected togather.
Air cleaner of the present invention is simple in structure, is suitable for operation, can conveniently realize ultraviolet disinfecting time control, can realize sterilization and the pure and freshization processing of air; Shell 2 is consistent with physical dimension with door 7 profiles, can simplify process for machining, effectively reduces production costs; Intermittent work is adopted in the Burdick lamp irradiation, reduces the abnormal flavour that purifies air when effectively sterilizing as far as possible, and saves electric energy.

Specific embodiment
1) operate as normal
Described air cleaner start, motor 4 drives fan 3 and is rotated in generation negative pressure in the body, the air of dirt is sucked in the body by the air inlet array 11 on the door 7, at first by drainage screen 8, high density net and photocatalytic active carbon are arranged in the drainage screen 8, can realize that the bulky grain dust filters and remove airborne harmful gas; Air after then filtering is realized the disinfecting process of filtered air through disinfection by ultraviolet light net 9; Then the air after the sterilization is realized the Electrostatic Absorption of minute dust granule through high-pressure electrostatic absorption net 10; Last anion generator and control circuit board 6 produce anion and enter into high-pressure electrostatic absorption net 10 left sides and mix the formation fresh air through the air after filtration, sterilization, the Electrostatic Absorption, by the pure and fresh machine of venthole array 12 air-outs on the door 7, realize air circulation through the suction function of passing through fan.
The work process of Burdick lamp intermittent irradiation: described air cleaner main switch 14 closures, system powers on by alternating current power supply 13, and working time relay coil 15 powers on, and Burdick lamp 17 is bright simultaneously; Behind the time-delay t1, working time relay normally-closed contact 18 disconnects, and Burdick lamp 17 goes out, while working time relay normally open contact 19 closures, and intermittent time relay coil 16 powers on; Behind the time-delay t2, intermittent time relay normally-closed contact 20 disconnects, 15 outages of working time relay coil, working time relay normally-closed contact 18 closures, Burdick lamp 17 energisings, working time relay normally open contact 19 disconnects simultaneously, 16 outages of intermittent time relay coil, intermittent time relay normally-closed contact 20 closures, working time relay coil 15 powers on, and so realizes the intermittent power on/off of Burdick lamp repeatedly.As preferred embodiment, working time relay delay time can be made as 10 seconds, and intermittent time relay delay time can be made as 50 seconds, finished a cycle of operation in 1 minute.
2) cleaning work
Described air cleaner needs the dust of periodic cleaning internal body, only need open door 7 during cleaning, take out drainage screen 8, disinfection by ultraviolet light net 9, high-pressure electrostatic absorption net 10, put in back the origin-location after clearing up dust respectively, in order to guarantee the installation order of drainage screen 8, disinfection by ultraviolet light net 9, high-pressure electrostatic absorption net 10, can adopt the mounting groove of 3 kinds of different sizes.
3) mounting means
This machine can be taked 3 kinds of mounting means: one, and on-land type is installed, i.e. mode shown in the accompanying drawing; Its two, vertically lifting is arranged in shell 2 back the wall hanging adnexa is installed; Its three, laterally lifting, the dextrorotation of position shown in the accompanying drawing turn 90 degrees, and arranges in shell 2 back the wall hanging adnexa is installed.
