What is the reason why the total power trip after boiling water in a rice cooker for a few minutes?

According to the maintenance experience, the total power supply of the rice cooker is off after boiling water for a few minutes, most of which are caused by poor thermostats, and a few are heated.

Severe local fever of the filament.

If other electrical appliances (including those with more power than the rice cooker) do not cause tripping, it means that the rice cooker has a hidden leakage or overcurrent fault and needs to be repaired.

The load is heavy, change to a high-power *** total power supply, be careful of danger.

Hello, it should be that the power supply of your home is unstable, and the voltage that may be required to boil water is too large, which causes the total power supply of your home to trip, especially if you are still turning on other electrical appliances with large power at that time, the trip will jump faster and more powerfully.

There are a couple of questions:

1. The contact contact of the rice cooker is not good, 2. The bottom of the rice cooker is deformed, resulting in poor contact;

3. The fuse is burned (if it burns, there will be no reaction, and the light will not be on, just replace one).

Does the rice cooker power meet the power requirements?

Are there other power-hungry appliances in the home environment at the same time? Such as electric water heaters, electric heaters, etc.

It should be noted that the total power cannot be plugged in at the same time, as it will exceed the total power load.

If it is not plugged in, it means that it is not the fault of the rice cooker, but the power trip protection caused by the total power exceeding the standard.

The electrical circuit of the rice cooker or the insulation resistance of the power cord of the rice cooker is smaller.

If your home is a socket installed in accordance with the provisions of the wiring, and the total voltage trips, you should replace the new main switch, and the new main gate is larger than the current main switch. The air switch can be bought either 40A or 45A.

If the air switch with leakage protection is responsible for the power supply of the socket, check whether the socket is splashed, damp or burned to carbon.

The total power supply trips a few minutes after the rice cooker boils water, which should be the rice cooker with a heavy load and the line can't take the rice cooker to work.

The most direct reason is that your rice cooker is leaking or the rice cooker is short-circuited, and you still have to check the rice cooker if it trips again.

This he should be a rice cooker, he has a protection from heat. He just measures that your water is boiling, and then he will cut off the power and play a protective role.

If the previous use is normal, but this kind of situation has occurred recently, the total power supply may be broken, if it is always so, the main switch is too, and it can be used by changing a current level that is larger than the current empty open.

1. The tripping of the rice cooker may be due to the deformation of the bottom of the inner pot of the rice cooker or the dirt, resulting in poor contact with the heating plate, reducing the thermal resistance of the heating conduction surface and increasing the thermal resistance, so that the rice cooker trips phenomenon.

2. It may also be because the rice cooker has a long service life, resulting in the failure of the rice cooker, and the rice cooker needs to be replaced in time or repaired by a repair shop.

3. If the heating plate of the rice cooker is partially melted and deformed when it is used, the deformed heating plate will make the surface of the heating plate unable to fit closely with the bottom of the pot when cooking, and form a gap, so that the heat cannot be completely transmitted, so that the phenomenon of tripping occurs, you can first observe whether the heating plate is deformed, if it is deformed, it needs to be replaced directly.

4. In the process of use, the insulating glue of the rice cooker is aged or deformed due to high temperature, which makes the magnetic switch of the rice cooker fail, resulting in the tripping of the rice cooker, and a new magnetic switch can be replaced at this time.

If it is tripping, it is generally a protection circuit action, and the electric pot is equipped with two kinds of protection, one is empty burning, and the other is overtemperature. If the home protector trips, it is caused by a short circuit or leakage.

What is the reason why the rice cooker trips in advance before the rice is cooked, what to do, how to repair the reason, first analyze the principle of heating and cooking and keeping warm in the rice cooker.

The rice cooker is heating up to investigate the cause of him, that is, it may be. Rice cooker. The electricity consumption is too great.

If the heating plate is too wet and leaking, open the bottom cover and dry it with a hair dryer. or the heating plate is not bad and short-circuited to the ground, and it can only be replaced.

If such a phenomenon occurs, either the pot is broken, or the temperature is too high and enters the protective state caused by your improper operation.

2. The rice cooker uses a heating plate to cook rice at the bottom of the aluminum pot. The heating plate has a built-in electricity**, which is controlled by an automatic switch. There is a round hole in the heating plate, and there is a warm and soft magnetism in the hole, which is pressed against the bottom of the pot by the spring.

This is a pure ferrite. At 100 or below, it can be attracted to a permanent magnet. However, when it rises to 103, it loses its magnetism and is no longer attracted to a permanent magnet.

3. When the switch button is pressed, the switch crossbar puts the magnet on the top of the soft magnet for temperature sensing; At this time, the hair ** is turned on and the heating begins. When the rice in the pot boils, the water in the pot gradually decreases. When the water starts to dry, the temperature in the pot rises from 100 degrees.

When it rises to 103, the temperature sensing soft magnet is not attracted by the magnet, and the pressure separates the contact points, and the power is cut off. At the same time, turn on another insulation circuit to keep the temperature of the rice at about 70.

Hello dear The reasons for this situation are as follows: 1. The bottom of the pot is not in good contact with the heating surface (deformed or foreign bodies); 2. Aging of magnetic steel thermostat; 3. The sensitivity is too high due to the deformation of the trip switch; 4. The long-term heating of the magnet reduces the Curie temperature point, resulting in the trip of the rice before it is cooked. Workaround:

1. Repair or replacement; 2. Remove the pot to see if the heating plate is deformed, if the deformation cannot be repaired, buy a new one and replace it; 3. Place the pot on the heating plate, gently tap the uneven part of the bottom of the pot, and find a way to make the bottom of the pot close to the surface of the heating plate. If it really doesn't work, go to the official repair office of the rice cooker for repair. The reason why the rice cooker trips when it is heated is that the power is too high, which causes the empty opening to trip, and it is recommended to replace it with a new one.

Hello, I'm glad to reply to you, the reasons and treatment methods for tripping when the rice cooker is heated: 1. The bottom of the pot is not in good contact with the heating surface (deformed or has foreign bodies); 2. Aging of magnetic steel thermostat; 3. The deformation of the trip switch causes the sensitivity of the spiritual head to be too high; 4. The long-term heating of the magnet reduces the Curie temperature point, resulting in the trip of the rice before it is cooked. Workaround:

1. Repair or replacement; 2. Remove the pot body to see if the heating plate has changed into a sedan hand shape, if the deformation cannot be repaired, buy a new one and replace it; 3. Place the pot on the heating plate, gently tap the uneven part of the bottom of the pot, and find a way to make the bottom of the pot close to the surface of the heating plate. If it really doesn't work, go to the official repair office of the rice cooker for repair. The reason why the rice cooker trips when it is heated is that the power is too high, which causes the air to trip, it is recommended to replace the new air open, I hope it will help you, and you can always find the teacher if you have other problems in the future.

I wish you all the best in your life.

Hello, I'm happy to answer your questions, typing more, please be patient, about five minutes left trillion good right reply, please don't worry, thank you. The problem of rice cooker water tripping without boiling may be that the magnet loses magnetism, which is a failure that is prone to occur in rice cookers that have been used for a long time; You need to replace the rice cooker or go to a professional repair shop for repair. In addition, the bottom of the pot is deformed or dirty, resulting in poor contact with the heating plate, which reduces the thermal resistance of the thermal conduction surface and increases the verticality, resulting in early tripping of the switch; Inspect the bottom of the inner pot.
