The heat of the electric ceramic furnace is used in the technical principle of infrared thermal heating. The nickel chromium wire of the furnace is used to generate heat to generate heat, which will emit infrared rays when generating heat.When heating, the electric ceramic furnace truly realizes a uniform heating function, which can perform continuous heating. In terms of power, it can be continuously adjusted from 100-2000W to truly realize the function of cultural and military fire.
What are the dangers of electric pottery stoves?
Evaporate skin moisture, causing skin drying
Most of the dangers of electric ceramic furnaces are reflected in the impact of the surface and inner layers of the skin.In common, it will not only make the skin temperature higher, but also expand the capillaries in the skin.At the same time, because more water in the skin is evaporated, it is easy to cause skin dryness and aging.
During outdoor barbecue, skin allergies and diseases are caused
Under the influence of outdoor sunlight, the infrared and ultraviolet rays emitted by the electrical furnace will cause greater harm to health.First, it will cause skin -related diseases, including allergies and redness; at the same time, the skin will also occur in dull pigment, which is directly reflected as the symptoms of sunburn.
It affects vision when the distance is too close
Do not rely on too close when using an electric pot furnace, let alone make your face, because infrared also has a certain impact on vision.Therefore, people with myopia themselves are best to use a longer spoon, and then operate the electric pot furnace at a farther distance.
What are the common faults of electric ceramic furnace
Electric ceramic furnace repair-fault phenomenon 1: no response after power-on, the indicator light does not light up
Analysis and maintenance: If the 18 -volt voltage is not output after power -on, the AC220 volt input voltage is first measured normally. If it is not normal, check the power cord and the power socket.Next, measure the DC voltage of 300 volts at both ends of the EC1. If there is no, check the current -limited resistance R1, rectifier d1, and filter capacitor EC1;Metro component.
If the 18 -volt voltage is normal, it is normal to measure the 5 volt voltage at both ends of the stabilization pipe or the filter capacitor EC3. If it is abnormal, check the resistor R7, the regulatory tube Z3, or the filter capacitor EC3; if the 5 volt voltage is normal, the LED indicator lightIf it is not bright, the U1 is detected and replaced.
Electric ceramic furnace repair-fault phenomenon 2: heating temperature cannot be adjusted
Analysis and maintenance: The cause of this failure is mostly two -way thyristor Q5 breakdown, causing AC220 volt electricity to directly add to both ends of nickel chromium alloy wires, the most heating power, and it is not adjustable.If Q5 and Q4 are normal, check the panel control circuit.
Electric ceramic furnace repair-fault phenomenon 3: After power-on, indicator lights are on, not heated
Failure maintenance: This failure is mostly damaged by the nickel chromium alloy wire heating disk, and it is commonly burned by nickel chromium alloy silk.
If the nickel chromium alloy wire heating plate is normal, check the two -way silicon heating circuit. The common cause is damaged by Q5.
If nickel -chromium alloy wire heating disks, Q5 and Q4 are normal, but still do not heated, check the panel control circuit, and can judge the ground resistance and ground voltage of each pin of CN1 and U1.
Electric ceramic furnace repair-fault phenomenon 4: fan after power-on does not transfer
Analysis and maintenance: The cause of this failure is either damaged by the fan control circuit Q3 or the fan is damaged.The ④ foot of the Q3 base connector CN1, the ground voltage of the foot to the ground is about 4.7 volts and 0 volts when the standby. If it is always 0 volts, check the ① foot circuit of the U1.
How to repair the electric ceramic furnace
Electric ceramics furnace repair method -The situation of power -through
If the electric ceramic furnace is powered on, the digital tube displays E2, and the bee will call the police, it may be poor contact with the motherboard (check the "main" 2P socket on the motherboard welding, fake welding, virtual welding and welding point falling off, sockets and thermal powerThe connection line is loose) or the thermocouple damage is damaged (the output of the thermocouple of the thermocouple of the thermocouple of the universal meter resistance should be the turnover; the thermocouple thermostat welding point falls off).At this time, you can try the "Main" 2P socket on the welding motherboard.Insert a fixed heat electric puppet, or replace the thermal power puppet.
Electric ceramic furnace repair method -when circuit failure
If the circuit part of the computing amplifier of the electric ceramic furnace is faulty, it can be measured (R7, R17, R16, R18, R22, R2, R10), capacitance (C4, C6, C8, C9, EC1) to measure the operational operation.A amplifier output voltage: The multimeter is adjusted to the DC voltage gear.The negative table pen connecting the main board "negative electrode" (foot or connected line in the middle of IC1L7805) is about 0.003V at room temperature at the normal temperature of the main board on the main board (near one end of the socket).
Check whether there are wrong parts in the integrated computing amplifier (with a good motherboard for comparison), welding, fake welding, virtual welding, welding point drop and whether the components are damaged.In this case, you can try to supplement the circuit of the welding motherboard computing amplifier, or replace the same parameter element device.
Electric ceramic furnace repair method -when it is poorly in contact
If the connection between the electric ceramic furnace lamp board and the motherboard is poor, check the 9P row plug on the motherboard and the 9P lines on the lamp board.Whether the line is loose, the same line should be turned on with the duct wire on the light board with a universal meter resistor gear.You can make up the 9P sockets, and line plugs on the lamp board.Or insert a solid lamp board to connect to the motherboard.Replace a line.
The above brief answers introduced several methods of electric ceramic furnace repair methods, hoping to solve difficulties for everyone.For electrical appliances, if you do n’t know how to do it, you should still ask professional maintenance personnel to solve the failure. If you deal with it without knowing it, it is easy to cause secondary damage.
