故障一、消毒柜出现漏电
 
原因:电子消毒柜中管状电热元件的封口机动车道过热而损坏;或是开关、定时器、插头、插座处的绝缘材料受潮或有异物;或是接地损坏,接地螺钉松动、锈蚀。
 
检修方法:
 
1.消毒柜通电后发现漏电现象,应立好切断电源并找出漏电原因。
 
2.拆下消毒柜的背板,消除电热管端部的封口材料,重新用山大SD-2\SD-4或“704”封口胶封口。
 
3.若是开关、定时器、插头、插座处的绝缘材料受潮或有异物时,可用电吹风把受潮部位吹干或清除脏物即可。
 
4.对于出现接地损坏,接地螺钉松动、锈蚀时,可重新安装接地螺钉,或打磨掉锈蚀层,使电阻不大于0.2即可。
 
故障二、电子消毒柜通电后就立好熔断保险丝
 
原因:电源线线芯之间或插头、插座中两极导线短路;继电器及低温型消毒柜中的高压变压器、风扇的线圈局部短路;管状电热元件封口的硅橡胶绝缘材料在高温下表面碳化,由乳白色变成深褐色而成为导体,造成引出线头和外壳之间短路;消毒柜的电气线路局部绝缘破坏,造成碰壳短路。
 
检修方法:
 
1.仔细检查插头、插座的绝缘情况,若有短路现象应重新接线。若是变压器、风扇的线圈局部短路,应更换同型号的元件。
 
2.若是绝缘材料在高温下表面碳化,可用细砂纸把碳化物打磨干净后,再用500V兆欧表测量引出线和外壳之间的绝缘电阻值》5M,然后再用硅橡胶封口。
 
3.若是消毒柜的电气线路局部绝缘破坏,造成碰壳短路时,可打开电子消毒柜底板,找出碰壳处,使其电气线路与外壳分开。
 
故障三、电子消毒柜通电后指示灯不亮
 
原因:电源插头和插座接触不良或是插头接线松脱;定时器损坏;指示灯坏了;继电器定组线圈烧断;消毒柜内部的保险丝断了。
检修方法:
 
1.拆开插头,检查接线是否有松脱现象,若有松脱现象,应重新接好或者拆开插座,用钳子把插座内的铜处调整好,使其接触良好;顺时针方向旋转定时旋钮,听有否齿轮有走动的声音。若无,挣开定时开关,旋紧压在凸轮上的螺帽,使其转运旋钮时能带动凸轮一起转运。
 
2.通电检查,若柜内温度有所升高,并能闻到臭氧气味,则是指示灯烧毁,应更换同型号的指示灯;按下启动按钮不放,若指示灯亮,再松开启动按钮,如指示灯灭,则说明断电器定组线圈烧断,应更换同型号的断电器,若是保险丝断了,应查出短路原因排除故障后,换上同规格的保险线。
 
故障四、高温型电子消毒柜指示灯亮但不发热
 
原因:管状发热元件的插头未插好;管状发热元件的插头和插座接触不良;电热丝烧烤;继电器常开触点严重氧化,造成加热器无法通电;温度控制器动触点和静触点严重氧化,造成接触不良。
 
检修方法:
 
1.当管状发热元件的插头未插好时,重新将插头插好。
 
2.若是管关发热元件的插头和插座接触不良,可拆开插座,用钳子把插座内的铜片调整好,使插头上的插脚和插座内的铜片接触良好。
 
3.若是内部电热丝烧断,更换功率相同、长度一样的新电热丝即可。
 
4.若是继电器常开触点严重氧化,可用细纱纸打磨触点,使之接触良好或是的同型号的继电器。
 
5.若是温度控制器动触点和静触点严重氧化,造成接触不良,断开电源后,打开消毒柜的背板,拆下温控器,用砂纸打磨触点,并用尖嘴钳整理弹簧的形状,以使动触点和静触点接触良好。
 
故障五、消毒柜发现温度偏高 所谓消毒柜温度偏高是指:在柜内空间的中部测试时,温度超过120C.
 
原因:温控器中的瓷米位置偏后,导致柜内的温度偏高;消毒柜在较长时间内不自动停机断电;继电器常开触点熔化,导致柜内温度偏高。
 
检修方法:
 
1.打开消毒柜背板,逆时针旋转标准螺钉,让瓷米前移,使柜内温度同刻度盘上的指示温度相当。
 
2.若是温控器触点熔化,造成了柜内温度过高时,可用薄刀片把动触点与静触点分开,再用细砂纸打磨触点,使其重新接触良好,若不行,应更换新温控器。
 
3.若是继电器常开触点熔化,导致柜内温度偏高,应更换同型号的断电器。
 
故障六、消毒柜发现温度偏低 所谓消毒柜温度低度,是指将温度计放在消毒柜空间中部测试时长时间达到110C.
 
原因:温控器的资粮位置偏前,导致柜内温度偏低;电热管烧坏或插座间接触不良;温控器动触点和静触点严重氧化或断电器常开触点严重氧化,使触点阻值变大,导致消毒柜温度偏低造成。
 
检修方法:
 
1.打开消毒柜背板,顺时针旋转校准螺钉,让瓷米后移,使柜内的温度同刻度盘上的指示温度相当。
 
2.若是电热管烧坏,可在切断电源后,用万用表的欧姆挡测量发热管两部电阻值。
 
3.正常时,电阻值应为160-170(每根电热管的功率为300W)若测得阻值为无穷大,测说明已烧坏,应死鬼;若电阻值正常,则说明电热管的插头与打插座间接触不良,应拆开插座,用小嘴钳修正插座内的弹簧片,使插头与插座间接触良好。
 
4.若是温控器动触点和静触点严重氧化或断电器常开触点严重后氧化,使触点阻值变大,导致消毒柜温度偏消毒柜保养常识:
 
1.用完的餐具必须先洗干净,将水擦干才放进消毒柜内,一些用户把带水的食具放入柜内又不经常通电,致使消毒柜的各电器元件及金属表面受潮氧化。如在红外发热管管座处出现接触电阻,易烧坏管座或其他部件,缩短消毒柜的使用寿命。
 
2.消毒柜是专门为消毒厨具而生产的,其它东西不能放进消毒柜内消毒,避免发生危险。
 
3.使用一段时间后要定期清洁柜内及外表面,使消毒柜保持干净卫生。清洁消毒柜时,先拔下电源插头,用干净的湿布擦拭消毒柜内外表面,禁止用水冲淋消毒柜。若太脏,可先用湿布蘸中性洗涤剂擦洗,再用干净的湿布擦净洗涤剂,最后用干布擦干水分。清洁时,注意不要撞击加热管或臭氧发生器。
 
4.每日通电一次,这样既能起到杀菌消毒的作用,又能延长消毒柜的使用寿命。
 
5.使用时,如发现石英加热管不发热,或听不到臭氧发生器高压放电所产生的“吱吱”声,说明消毒柜出了故障,应停止使用,送维修部门修理。
 
6.消毒柜应水平放置在周围无杂物的干燥通风处。
 
想要延长家用电器的使用寿命,小飞电器小编提醒大家,遇到家电故障问题,需要请专业的维修人员进行维修,才能保证家电的正常使用。
With the continuous improvement of people's living standards, while paying attention to physical health, the requirements for health conditions are also higher and higher, which makes the tableware disinfection cabinet gradually become an indispensable electrical equipment in the family. When the disinfection cabinet of household appliances is used, it will cause the failure of the disinfection cabinet for some reasons, such as the use environment of the disinfection cabinet, incorrect operation and maintenance, etc. In order to use the sterilizer better, Xiaofei Electric Co., Ltd. collected the common faults and maintenance skills of the sterilizer for your reference.
 
Fault 1. Leakage of disinfection cabinet
 
 
 
Causes: the sealing motorway of tubular electric heating elements in the electronic disinfection cabinet is damaged due to overheating; the insulation materials at the switch, timer, plug and socket are damp or have foreign matters; or the grounding is damaged, and the grounding screw is loose and rusted.
 
 
 
Maintenance method:
 
 
 
1. If leakage is found after the disinfection cabinet is powered on, cut off the power supply and find out the cause of leakage.
 
 
 
2. Remove the back plate of the disinfection cabinet, eliminate the sealing material at the end of the electric heating pipe, and seal it with SD-2 \ sd-4 or "704" sealing glue of Shanda.
 
 
 
3. If the insulating materials at the switch, timer, plug and socket are damped or there are foreign matters, the damped parts can be dried or the dirt can be removed with an electric blower.
 
 
 
4. If the grounding screw is loose or rusted, the grounding screw can be reinstalled, or the rusted layer can be polished off, so that the resistance is no more than 0.2.
 
 
 
Fault 2. Set up the fusing fuse after the electronic disinfection cabinet is powered on
 
 
 
Causes: short circuit between power line cores or two pole wires in plugs and sockets; partial short circuit between relay and coil of high-voltage transformer and fan in low-temperature disinfection cabinet; carbonization of silicon rubber insulation material sealed by tubular electric heating element on the surface under high temperature, which changes from milky white to dark brown to become conductor, causing short circuit between lead out wire head and shell; partial electric circuit of disinfection cabinet The insulation is damaged, causing a short circuit to the shell.
 
 
 
Maintenance method:
 
 
 
1. Check the insulation of plug and socket carefully, and reconnect if there is short circuit. If the coil of transformer and fan is short circuited locally, the components of the same model shall be replaced.
 
 
 
2. If the surface of the insulating material is carbonized under high temperature, the carbide can be polished with fine sandpaper, and then the insulation resistance between the outgoing line and the shell shall be measured with a 500V megger (5m), and then sealed with silicone rubber.
 
 
 
3. If the local insulation of the electrical circuit of the disinfection cabinet is damaged, resulting in the short circuit of the shell, the bottom plate of the electronic disinfection cabinet can be opened to find out the place where the shell is touched, so as to separate the electrical circuit from the shell.
 
 
 
Fault 3. The indicator light of the electronic disinfection cabinet is not on after power on
 
 
 
Causes: poor contact between power plug and socket or loose plug wiring; timer damaged; indicator light broken; relay set coil burnt out; fuse inside disinfection cabinet broken.
 
Maintenance method:
 
 
 
1. Disconnect the plug and check whether the wiring is loose. If there is loose phenomenon, reconnect or disconnect the socket. Use pliers to adjust the copper part in the socket to make it in good contact. Turn the timing knob clockwise to hear whether there is a moving sound of the gear. If not, open the timing switch, tighten the nut pressed on the cam, so that the cam can be driven to transfer together when the knob is transferred.
 
 
 
2. Power on inspection: if the temperature in the cabinet rises and the smell of ozone can be smelled, the indicator light is burnt out, and the indicator light of the same model shall be replaced; press the start button and keep it on, if the indicator light is on, then release the start button, if the indicator light is off, it means that the fixed coil of the breaker is burnt out, and the breaker of the same model shall be replaced. If the fuse is broken, the cause of the short circuit shall be found out and the fault shall be eliminated After that, put on the fuse of the same specification.
 
 
 
Fault IV. indicator light of high temperature electronic disinfection cabinet is on but not hot
 
 
 
Causes: the plug of the tubular heating element is not inserted properly; the plug and socket of the tubular heating element are in poor contact; the electric heating wire is barbecued; the normally open contact of the relay is seriously oxidized, resulting in the heater being unable to power on; the dynamic contact and the static contact of the temperature controller are seriously oxidized, resulting in poor contact.
