FEEGOO Hand dryer ndi chida chaukhondo choumitsa manja kapena kuumitsa manja m'bafa.Imagawidwa mu induction automatic hand dryer ndi chowumitsira pamanja pamanja.Amagwiritsidwa ntchito makamaka m'mahotela, malo odyera, mabungwe ofufuza zasayansi, zipatala, malo osangalatsa a anthu onse komanso bafa la banja lililonse.Chida cholondolera mpweya chimayikidwa pamalo otulutsira mpweya wa chowumitsira m'manja, ndipo pa chipangizo cholozera mpweya pamakhala masamba owongolera mpweya.Pulogalamu.

Mfundo yogwirira ntchito ya chowumitsira m'manja nthawi zambiri ndikuti sensa imazindikira chizindikiro (dzanja), chomwe chimayendetsedwa kuti chitsegule chiwongolero chozungulira chotenthetsera ndi kuwulutsa kozungulira, ndikuyamba kutentha ndi kuwomba.Chizindikiro chodziwika ndi sensa chikasowa, kukhudzana kumatulutsidwa, dera lotenthetsera ndi kuwulutsa kozungulira kumachotsedwa, ndipo kutentha ndi kuwomba kumayimitsidwa.Zowumitsira m'manja zotengera kutentha komanso kuthamanga kwambiri zimatenthedwa kwambiri.Nthawi zambiri, mphamvu yotentha imakhala yayikulu, pamwamba pa 1000W, pomwe mphamvu yamagalimoto ndi yaying'ono kwambiri, yochepera 200W.Zowumitsira pamanja zamtundu wa FEEGOO ndizofanana ndi zomwe zimachitika.Njirayi imawumitsa manja pang'onopang'ono, nthawi zambiri kuposa masekondi 30.Zimakhala phokoso pang'ono, choncho zimakhudzidwa ndi nyumba zaofesi ndi zosowa zina za malo opanda phokoso.chisomo.

Cholakwika 1:

Ikani dzanja lanu mu mpweya wotentha, palibe mpweya wotentha umene umatulutsidwa, mpweya wozizira wokha ndi womwe umatulutsidwa.

Kusanthula ndi kukonza: Pali mpweya wozizira womwe ukutuluka, zomwe zikuwonetsa kuti chowombera chimagwira ntchito, ndipo mawonekedwe a infrared ndi kuwongolera kwawo ndizabwinobwino.Pali mpweya wozizira wokha, kusonyeza kuti chowotcha ndi chotseguka dera kapena waya ndi lotayirira.Pambuyo poyang'anitsitsa, waya wowotchera amamasuka.Pambuyo polumikizanso, pali mpweya wotentha womwe umatuluka, ndipo cholakwikacho chimachotsedwa.

Cholakwika 2:

Pambuyo kuyatsa.Manja sali pa malo otentha mpweya.Mpweya wotentha umawomba mosalamulirika.

Kusanthula ndi kukonza: Pambuyo pofufuza, palibe kuwonongeka kwa thyristor.Pambuyo pochotsa optocoupler, ntchitoyo inabwerera mwakale, ndipo vutolo linathetsedwa.

Cholakwika 3:

Dzanja limayikidwa mu mpweya wotentha, koma palibe mpweya wotentha womwe umatulutsidwa.

Kusanthula ndi kukonza: fufuzani kuti zimakupiza ndi chotenthetsera ndi zachilendo, fufuzani kuti chipata cha thyristor alibe choyambitsa voteji, ndipo fufuzani kuti c-mzati wa ulamuliro triode VI ali amakona anayi mafunde chizindikiro linanena bungwe., ④ Kukaniza kutsogolo ndi kumbuyo pakati pa mapiniwo ndi kosatha.Nthawi zambiri, kukana kutsogolo kuyenera kukhala angapo m, ndipo kukana kumbuyo kuyenera kukhala kosatha.Iwo amaweruzidwa kuti mkati photosensitive chubu ndi lotseguka dera, chifukwa chipata cha thyristor kusapeza choyambitsa voteji.Sitingayatse.Pambuyo posintha optocoupler, vutoli limathetsedwa.

Kuti athandizire kukonza, kuzungulira kwa makinawo kumawunikidwa, ndipo chojambula chozungulira chimajambulidwa (onani chithunzi chophatikizidwa).

Ndipo fotokozani zomwe zimayambitsa zolakwika ndi njira zosavuta zopezera.

1. mfundo yozungulira

Pozungulira, oscillator wa 40kHz amapangidwa ndi V1, V2, R1, ndi C3, ndipo kutulutsa kwake kumayendetsa chubu cha infuraredi D6 kuti chitulutse kuwala kwa infrared 40kHz.Dzanja la munthu likafika pansi pa chowumitsira dzanja, kuwala kwa infrared komwe kumawonetsedwa ndi dzanja kumalandiridwa ndi photocell D5.Sinthani kukhala chizindikiro cha DC chomwe chili ndi theka-wave.Chizindikirocho chimaphatikizidwa ndi malo abwino olowera gawo loyamba la amplifier yogwira ntchito kudzera pa C4 kuti akulitse, ndipo magetsi ang'onoang'ono okondera amawonjezedwa ku terminal yoyipa kuti apewe kusokoneza kwazing'ono.Chizindikiro chokulirapo chimachokera ku ① pini kupita ku R7, D7, C5 kuti ipangidwe ndikusalaza kuti ikhale chizindikiro cha DC.Imatumizidwa kumalo olowera abwino a pini ⑤ a gawo lachiwiri op amp kuti afananize ndi kukulitsa.Kupindika kwa gawo lachiwiri la op amp kumatsimikiziridwa ndi chogawitsa voteji cha R9 ndi R11 cholumikizidwa ndi cholumikizira cholakwika cha pini ⑥.R10 ndiye wotsutsa wabwino wa op amp, ndipo pamodzi ndi C5 ndi C6 amapanga dera lochedwa kuti aletse dzanja lomwe lapezeka kuti lisasunthe.Kusokoneza komweku kumabweretsa kuzima kwa magetsi.Pini ya amplifier yogwira ntchito ⑦ ikatulutsa mulingo wapamwamba, V3 imayatsidwa.Chiwongolero chowongolera chimayatsa mphamvu ku heater ndi blower.

2. Zomwe zimayambitsa zolakwika ndizovuta

Cholakwika 1: Kuwala kowunikira kumayatsidwa mphamvu ikayatsidwa.Koma palibe mpweya wotentha womwe unatuluka pambuyo pofikira.

Kusanthula kwa kuthekera kuti fan ndi chowotchera zidzalephera nthawi yomweyo ndizochepa kwambiri.Nthawi zambiri zimakhala chifukwa cholumikizirana chathyoka kapena sichikugwira ntchito.Ngati J sakugwira ntchito, zitha kutanthauza kuti V3 siyikuyenda;amplifier ntchito alibe zotuluka;D6 ndi D5 amalephera;V1 ndi V2 samayamba kunjenjemera.Kapena 7812 yawonongeka chifukwa palibe magetsi a 12V.

Mukayang'ana, fufuzani kaye ngati pali voteji ya 12V.Ngati alipo, fikirani kuyesa ndikuwona ngati mulingo wa pini ⑦ wa amplifier yogwira ntchito yasintha.Ngati pali kusintha, yang'anani V3 ndikubwezera kumbuyo;ngati palibe kusintha, yang'anani dera la amplifier ntchito, kutembenuka kwa photoelectric ndi oscillation circuit patsogolo.

Cholakwika 2: Mphamvu ikatsegulidwa, chowunikira chimayatsidwa.Koma sensitivity induction ndi yotsika.

Kuphatikiza pa kusokonezeka kwa dera la amplifier, vuto ili nthawi zambiri limayamba chifukwa cha kutulutsa kofiira komanso machubu olandila akuipitsidwa ndi fumbi.Ingosambitsani.
