What does it mean when 01 and 04 are written on the plug on the electric cooker?

0 is the abbreviation of the English letter out to indicate that the operation is closed and the operation is canceled.

1 is an abbreviation for the English letter in, which means open. Enter the system to run. This is what I know the meaning of the numbers on the plug.

If the plug on the electric pot says 01 and 04, it may be the serial number, which may be the wiring inside, or it may be her own serial number.

Chinese plugs cannot be used in most foreign countries, so they need to be produced according to the local plug or equipped with a conversion socket At present, the types of conversion plugs are mainly divided into these categories: British standard, national standard, American standard, European standard, South African standard, Italian standard.

Conversion socket. It is to install different types of plugs at one end, and connect to the power socket at the other end, so that the domestic electrical socket can also be connected to the international power supply. Good conversion socket jacks are in line with the standard, and will not be like those small stalls on the zero products like the plug length does not meet the specifications, and soon loose and fall off, broken can not find the warranty, the current market reputation is good Kelaibo, stable not to fall these two brands of conversion plug quality is very passable, durable.

In addition, the standard voltage in some regions (such as Taiwan, Japan, the United States, and Canada) is 110 volts, and the use of domestic 220V design electrical appliances will not be damaged, but it cannot reach the maximum power.

The manufacturer's internal ** needs circuit diagram comparison.

The 0 and 1 rubbed on the rice cooker should be a sign of cooking rice, that is, you can use this mark to determine whether your rice is cooked or not.

A plug has the meaning of Lingyin and Lin Si written on it, that is, one of his standards and specifications.

The black wire is the plug from the pressure switch plugged into the red socket and the other plug plugged into the white socket.

The red line is inserted into the red head, and the black line is inserted into the white head.

RT is a thermal element and SW1 is a switch.

RT is a thermistor i.e. an internal tantalum sensor, and SW1 is a switch. The red plug is inserted into the red socket and the black wire is inserted into the white socket. I don't know if I can help you?

Machine failure is recommended to bring after-sales maintenance, which city and which district you are in.

To explain, the trademark of the electric steamer is written as 220V, which means that the voltage used by the electric steamer is 220V, which is the electricity used in our home. The 250V marked on the plug means that the plug can not break down at 250 or 10A, which is a kind of data for our safety.

The rated voltage of the electric steamer is 220V, but the 250V of the plug is the maximum voltage that the plug can withstand. Nowadays, electrical products, appliances and plugs are separated, and sometimes the plugs are multi-functional and can be used in other high-power appliances.

Write 220V on the electric steamer is the applicable voltage marked, and write 250V on the plug to say the highest voltage that the plug and wire can withstand, do not exceed this voltage.

The 250V written on the plug indicates that the maximum withstand voltage of the plug is 250V, and the 250V on the electric steamer indicates that its working voltage is 250V.

It is a three-pin socket, and the upper hole is the ground wire, the left zero (N) and the right fire (L). In general, single-phase electrical equipment, especially mobile electrical equipment, should use a three-pin plug and a matching three-prong socket. The three-pin socket has a special protection zero (ground) jack, and when using the zero connection protection, some people often only connect the terminal head of this hole directly with the neutral wire introduced into the socket only in the bottom of the socket, which is extremely dangerous.

In the unlikely event that the neutral wire of the power supply is disconnected, or if the fire (phase) wire or neutral wire of the power supply is reversed, the metal parts such as the housing will also carry the same voltage as the power supply, which will lead to electric shock. Therefore, the dedicated grounding jack should be connected to the dedicated protective ground wire when wiring.

Generally, it is a current-limiting resistor, and the resistance value is generally between 100-470K.

Because of the high contact resistance between the plug and the socket.

The electric hot pot uses a single-phase three-core textile flexible wire as the power lead, and the plug at one end of the power lead with a jack should be inserted into the electric heating socket of the pot body first, and then the switch of the thermostat device should be placed in the middle or appropriate position. Usually put it on the high temperature at the beginning, and after the water is boiled, it can be placed in the heat preservation mode. Be careful to have a good grounding.

There are several reasons for this:

1. The contact resistance between the plug and the socket is large. The power of the medium electric wok is about 2000 watts, the working current is nearly 10 amps, if there is a 3 ohm contact resistance, the voltage drop between the plug and the socket will be 3x10 = 30 volts voltage drop, the power is up: 30x10 = 300 watts, obviously it will burn the plug socket.

2. The plug is burned, the socket is not replaced together, and although the contact resistance has been reduced, the hidden danger is still there.

3. The quality of the replaced plug is poor. so that it burned out again and again.

4. The starting reason should be the poor quality of the socket or the serious corrosion of the internal copper sheet. The manufacturer's original plug should meet the requirements of high current, and the plug is burned out due to the socket, so only care about changing the plug.

This situation must be taken very seriously, and it is likely to lead to a fire accident.

Solution: Buy a new set of plugs and sockets from genuine manufacturers. If the power exceeds 2000 watts, buy a 16A plug socket. When replacing, clean the oxide on the surface of the socket and plug wire, and tighten a few screws.

Reasons why the plug of the electric wok has been burned out repeatedly: 1Inferior plugs, sockets, --- metal sheets are not brass but iron sheets.

2.The plug is in poor contact with the socket and is too loose.

3.The power of the plug and socket is too low.

Solution: Use a copper plug and socket with a higher power and good contact.

Long-term use causes the plug friction seat to be deformed and burned out by the heated copper sheet. It is best to unplug it after use, and do not plug it into the wiping seat for a long time.

Maybe the current is too large to exceed the load of the line, change to a plug that can withstand a large point of current, and try.

It has nothing to do with the pot, the heat of the pot is the same, mainly caused by the poor quality of the wire, try not to turn on the electricity, the power is too large and the wire will heat and burn. The smoke is caused by poor contact between the jack and the power cord, because the poor contact causes internal ignition, and the ignition temperature rises, so it smokes. In the event of such a fault, the power cord should not be replaced hastily, because the jack is already damaged.

Even if you replace the power cord with a new one, it will be burned again, and the jack and power cord must be replaced together, and the fault will be completely eliminated.
