故障一、消毒柜出現漏電

 

原因：電子消毒柜中管狀電熱元件的封口機動車道過熱而損壞；或是開關、定時器、插頭、插座處的絕緣材料受潮或有異物；或是接地損壞，接地螺釘松動、銹蝕。

 

檢修方法：

 

1.消毒柜通電后發現漏電現象，應立好切斷電源并找出漏電原因。

 

2.拆下消毒柜的背板，消除電熱管端部的封口材料，重新用山大SD-2\SD-4或“704”封口膠封口。

 

3.若是開關、定時器、插頭、插座處的絕緣材料受潮或有異物時，可用電吹風把受潮部位吹干或清除臟物即可。

 

4.對于出現接地損壞，接地螺釘松動、銹蝕時，可重新安裝接地螺釘，或打磨掉銹蝕層，使電阻不大于0.2即可。

 

故障二、電子消毒柜通電后就立好熔斷保險絲

 

原因：電源線線芯之間或插頭、插座中兩極導線短路；繼電器及低溫型消毒柜中的高壓變壓器、風扇的線圈局部短路；管狀電熱元件封口的硅橡膠絕緣材料在高溫下表面碳化，由乳白色變成深褐色而成為導體，造成引出線頭和外殼之間短路；消毒柜的電氣線路局部絕緣破壞，造成碰殼短路。

 

檢修方法：

 

1.仔細檢查插頭、插座的絕緣情況，若有短路現象應重新接線。若是變壓器、風扇的線圈局部短路，應更換同型號的元件。

 

2.若是絕緣材料在高溫下表面碳化，可用細砂紙把碳化物打磨干凈后，再用500V兆歐表測量引出線和外殼之間的絕緣電阻值》5M，然后再用硅橡膠封口。

 

3.若是消毒柜的電氣線路局部絕緣破壞，造成碰殼短路時，可打開電子消毒柜底板，找出碰殼處，使其電氣線路與外殼分開。

 

故障三、電子消毒柜通電后指示燈不亮

 

原因：電源插頭和插座接觸不良或是插頭接線松脫；定時器損壞；指示燈壞了；繼電器定組線圈燒斷；消毒柜內部的保險絲斷了。

檢修方法：

 

1.拆開插頭，檢查接線是否有松脫現象，若有松脫現象，應重新接好或者拆開插座，用鉗子把插座內的銅處調整好，使其接觸良好；順時針方向旋轉定時旋鈕，聽有否齒輪有走動的聲音。若無，掙開定時開關，旋緊壓在凸輪上的螺帽，使其轉運旋鈕時能帶動凸輪一起轉運。

 

2.通電檢查，若柜內溫度有所升高，并能聞到臭氧氣味，則是指示燈燒毀，應更換同型號的指示燈；按下啟動按鈕不放，若指示燈亮，再松開啟動按鈕，如指示燈滅，則說明斷電器定組線圈燒斷，應更換同型號的斷電器，若是保險絲斷了，應查出短路原因排除故障后，換上同規格的保險線。

 

故障四、高溫型電子消毒柜指示燈亮但不發熱

 

原因：管狀發熱元件的插頭未插好；管狀發熱元件的插頭和插座接觸不良；電熱絲燒烤；繼電器常開觸點嚴重氧化，造成加熱器無法通電；溫度控制器動觸點和靜觸點嚴重氧化，造成接觸不良。

 

檢修方法：

 

1.當管狀發熱元件的插頭未插好時，重新將插頭插好。

 

2.若是管關發熱元件的插頭和插座接觸不良，可拆開插座，用鉗子把插座內的銅片調整好，使插頭上的插腳和插座內的銅片接觸良好。

 

3.若是內部電熱絲燒斷，更換功率相同、長度一樣的新電熱絲即可。

 

4.若是繼電器常開觸點嚴重氧化，可用細紗紙打磨觸點，使之接觸良好或是的同型號的繼電器。

 

5.若是溫度控制器動觸點和靜觸點嚴重氧化，造成接觸不良，斷開電源后，打開消毒柜的背板，拆下溫控器，用砂紙打磨觸點，并用尖嘴鉗整理彈簧的形狀，以使動觸點和靜觸點接觸良好。

 

故障五、消毒柜發現溫度偏高 所謂消毒柜溫度偏高是指：在柜內空間的中部測試時，溫度超過120C.

 

原因：溫控器中的瓷米位置偏后，導致柜內的溫度偏高；消毒柜在較長時間內不自動停機斷電；繼電器常開觸點熔化，導致柜內溫度偏高。

 

檢修方法：

 

1.打開消毒柜背板，逆時針旋轉標準螺釘，讓瓷米前移，使柜內溫度同刻度盤上的指示溫度相當。

 

2.若是溫控器觸點熔化，造成了柜內溫度過高時，可用薄刀片把動觸點與靜觸點分開，再用細砂紙打磨觸點，使其重新接觸良好，若不行，應更換新溫控器。

 

3.若是繼電器常開觸點熔化，導致柜內溫度偏高，應更換同型號的斷電器。

 

故障六、消毒柜發現溫度偏低 所謂消毒柜溫度低度，是指將溫度計放在消毒柜空間中部測試時長時間達到110C.

 

原因：溫控器的資糧位置偏前，導致柜內溫度偏低；電熱管燒壞或插座間接觸不良；溫控器動觸點和靜觸點嚴重氧化或斷電器常開觸點嚴重氧化，使觸點阻值變大，導致消毒柜溫度偏低造成。

 

檢修方法：

 

1.打開消毒柜背板，順時針旋轉校準螺釘，讓瓷米后移，使柜內的溫度同刻度盤上的指示溫度相當。

 

2.若是電熱管燒壞，可在切斷電源后，用萬用表的歐姆擋測量發熱管兩部電阻值。

 

3.正常時，電阻值應為160-170（每根電熱管的功率為300W）若測得阻值為無窮大，測說明已燒壞，應死鬼；若電阻值正常，則說明電熱管的插頭與打插座間接觸不良，應拆開插座，用小嘴鉗修正插座內的彈簧片，使插頭與插座間接觸良好。

 

4.若是溫控器動觸點和靜觸點嚴重氧化或斷電器常開觸點嚴重后氧化，使觸點阻值變大，導致消毒柜溫度偏消毒柜保養常識：

 

1.用完的餐具必須先洗干凈，將水擦干才放進消毒柜內，一些用戶把帶水的食具放入柜內又不經常通電，致使消毒柜的各電器元件及金屬表面受潮氧化。如在紅外發熱管管座處出現接觸電阻，易燒壞管座或其他部件，縮短消毒柜的使用壽命。

 

2.消毒柜是專門為消毒廚具而生產的，其它東西不能放進消毒柜內消毒，避免發生危險。

 

3.使用一段時間后要定期清潔柜內及外表面，使消毒柜保持干凈衛生。清潔消毒柜時，先拔下電源插頭，用干凈的濕布擦拭消毒柜內外表面，禁止用水沖淋消毒柜。若太臟，可先用濕布蘸中性洗滌劑擦洗，再用干凈的濕布擦凈洗滌劑，最后用干布擦干水分。清潔時，注意不要撞擊加熱管或臭氧發生器。

 

4.每日通電一次，這樣既能起到殺菌消毒的作用，又能延長消毒柜的使用壽命。

 

5.使用時，如發現石英加熱管不發熱，或聽不到臭氧發生器高壓放電所產生的“吱吱”聲，說明消毒柜出了故障，應停止使用，送維修部門修理。

 

6.消毒柜應水平放置在周圍無雜物的干燥通風處。

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.
