What is the reason why the rice cooker cooks and keeps jumping

Intelligence has become one of the hottest topics in the home appliance industry, and home appliance manufacturers have laid out their own smart strategies, whether in e-commerce or physical stores, you can see a variety of smart home appliances. As ordinary consumers, we feel the convenience, safety and speed brought by intelligence. The rice cooker is an electrical appliance that every family has, and it is used to cook rice, so why does the rice cooker jump after boiling for a while, let's find out together.

Why does the rice cooker jump after boiling for a while What is the reason why does the rice cooker jump after cooking for a while.

The rice cooker works by placing the inner pot where the food is served to heat up.

plate, so that the bottom of it is attached to the temperature-limiting medium temperature sensitive soft magnet in the center of the heating plate. Press the key switch to the permanent magnet below the soft magnet.

i.e. rise to contact with a soft magnet; At this time, the pot has not yet heated up, and the soft magnet is at Curie temperature.

Below, it is ferromagnetic.

It can be magnetized by a permanent magnet and held at a high point. Continue to heat the food in the pot for a period of time until the food is cooked through. But sometimes the rice cooker will jump after boiling for a while, and there are several reasons for this:

1. The bottom of the pot is not in good contact with the heating surface (deformed or has foreign bodies).

Second, the magnetic steel temperature limiter is aging.

3. The sensitivity is too high due to the deformation of the trip switch.

Fourth, the long-term heating of the magnet reduces the temperature point of the Curie, resulting in the trip of the rice before it is cooked.

Its 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 body on the heating plate, gently knock on 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.

It may be that the contact gasket inside has been deformed for a long time, and the gasket can't touch another gasket after pressing the cooking switch, so the power-on fails, you bend the gasket a little and try it.

I used to work in home appliance maintenance, it should be the contact gasket inside (the one in the middle of the circle) has been deformed for a long time, and the gasket can't touch another gasket after pressing the cooking switch, so the power-on fails, you bend the gasket a little and try it, and if it doesn't work, replace it with a new one.

It may be that your rice cooker has been used for a long time, or that you have not dried the bottom of the rice cooker properly when you usually use it.

Cause. 1) The bottom of the pot is not in good contact with the heating surface (deformed or there are foreign objects).

2) If the core of the magnet is broken, it needs to be replaced.

3) The sensitivity is too high due to the deformation of the trip switch.

Workaround steps.

1) If the rice cooker always jumps to the state of keeping warm when the rice is not cooked in the pot, first check whether there is dirt between the inner tank of the pot and the heating plate, and if so, it needs to be cleaned up.

2) If the pot rice cooker does not have any "observable" abnormal phenomenon, but it jumps to keep warm when the rice is not cooked, it is due to the aging of the "magnetic steel thermostat" in the middle of the heating plate, the reason is that in the use of the pot, the spring in the magnetic thermostat is often at high temperature, and the magnet in the thermostat will suddenly disappear when the temperature of the pot is higher than 103 degrees (when the water in the pot is boiled dry), and this temperature is called "Curie point temperature"; After the magnetism disappears, the spring in the thermostat resets the thermostat, and the circuit is turned to a state of insulation.

When you are cooking, have you noticed the thing in the middle of the electric tray that can bounce up and press down? It's called a temperature switch. It has a magnet made of a special material inside it:

When it is below 103 degrees Celsius, its magnetism is normal, and it can attract the iron connecting rod below, and the iron connecting rod resists the switch to electrify the heating plate. When the rice is cooked, the rice at the bottom of the rice pot begins to paste the pot, and the temperature will exceed 100 degrees Celsius, when it reaches 103 degrees Celsius, the magnet suddenly loses its magnetism, and the iron connecting rod is released, so that the switch is disconnected, and the electric heating plate stops heating, completing the whole process of cooking.

1. 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. When it is at or below 100 degrees Celsius, it can be attracted to a permanent magnet. However, when it rises to 103 degrees Celsius and reaches the Curie point, it loses its magnetism and is no longer attracted by a permanent magnet.

Pull. 2. When the switch button is pressed, the switch crossbar puts the magnet on the top of the temperature sensing soft magnet, at this time, the hair is turned on and starts to heat. 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 Celsius. When it rises to 103 degrees Celsius, the temperature sensing soft magnet is not attracted by the magnet, and the lever of the switch decreases due to the elastic force of the spring and its own gravity, 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 degrees Celsius.

The reason why the rice cooker jumped before it was cooked.

When the rice cooker is cooking, if the rice in the steel jumps to the insulated state before it is cooked, there are three common reasons:

1. The steel bottom is not in good contact with the heating surface, which may be due to the deformation of the bottom of the cylinder or the presence of foreign objects.

2. It may be that the magnetic steel thermostat is aging and needs to be replaced.

3. It may be that the sensitivity is too high due to the deformation of the jump switch.

The rice cooker will jump out on its own, and now that this phenomenon occurs, you can check whether the rice cooker is malfunctioning. Or it is that the temperature is high enough due to improper operation and enters a protective state.

It is because the rice cooker is a home smart product, the power meets the standard, the time limit meets the standard, and it will generally trip by itself, which is very safe.

The main reason is that the rice cooker is set with a trip switch, which will automatically trip when the set time is reached.

Because there are some programs set in the rice cooker to achieve the purpose of timing switch, and it can also prevent danger.

The rice cooker jumps in the middle of the power grid because of the unstable power grid voltage, aging wires, short circuits in the lines, excessive load, poor exhaust and other factors. Here's the detailed analysis:

1.The grid voltage is unstable.

When the grid voltage is unstable, the rice cooker may trip because the voltage is too high or too low. Especially during thunderstorms, during peak hours, or when neighbors are using high-power appliances at the same time, the grid voltage can be unstable.

2.Aging of wires.

After years of use, the wire will have problems such as aging, warping, and corrosion, which will lead to the line ignition and the inability to conduct electric energy normally. If the wires are aged, the wires used in the rice cooker will not be able to transmit power properly, resulting in tripping.

3.Short circuit in the line.

Short circuit refers to a short circuit between wires that causes a circuit fault in the remaining socks. When the resistance in the line is suddenly reduced, a large amount of current will flow through, which may lead to overload of the line, ignition and other conditions. If there is a short circuit in the wires used in the rice cooker, it will cause tripping.

4.Excessive load.

The rice cooker needs to consume a certain amount of electricity when working, and if the resistance in the rice cooker becomes larger, the current will increase and the load will also increase. If the load is too high, it will cause tripping.

5.Poor exhaust.

Some rice cookers are designed with a pressure-controlled switch to cook rice when the internal pressure reaches a certain level. If the gas encapsulated inside the rice cooker cannot be removed smoothly, it will cause the pressure to increase, triggering the pressure switch and tripping.

To sum up, there are many reasons for the rice cooker to jump in the middle of the trip, there are unstable grid voltage, aging wires, short circuits in the line, excessive load, poor exhaust and other factors, we need to pay attention to every detail when using, and carry out proper maintenance to reduce the possibility of the rice cooker jumping.

A rice cooker is a kitchen appliance that we often use in our daily life, and its main function is to cook rice, hot rice, steam, and so on. However, sometimes we may encounter some uncommon problems when using rice cookers. One of them is that the rice cooker does not jump when cooking.

So, how is this problem solved? 1. Reasons for the existence of the problem1The automatic disconnection of the alarm function is invalid

Rice cookers are usually equipped with an automatic power-off function. When the temperature of the inner tank reaches a certain level, it will switch from the heating state to the heat preservation state. If the auto-power-off function fails, the rice cooker will not be able to automatically switch to the keep warm state, resulting in mushy or dry rice.

2.Lack of water: Rice cookers cook rice in the ratio of rice to water, if the ratio of water is insufficient or incorrect, it will cause the rice cooker to not jump, and the cooked rice grains will be hard and dry, and the taste will not be good.

3.Faulty bottom pressure switch: The bottom of the rice cooker is usually equipped with a pressure switch, if this switch is damaged or aged, it will cause the rice cooker to not jump.

2. How to solve the problem 1Check the automatic power-off function: If you suspect that the problem is caused by the failure of the automatic power-off function, you need to check whether the control part and circuit board of the rice cooker are normal, and if you find a problem, you need to replace or repair it.

2.Adjust the ratio of rice to water: If lack of moisture is the cause of the problem, you need to check the rice cooker instruction manual, which recommends the ratio of rice to water.

3.Replace the bottom pressure switch: If the bottom pressure switch is faulty, you need to disassemble the rice cooker to check it, find the faulty switch, and replace it with a new switch part.

In short, when we find that the rice cooker will not jump when cooking, we must first find out where the problem is, and then take corresponding measures to repair it.

The automatic power trip of the rice cooker is because there is a short circuit in the heating ring or circuit board of the rice cooker, so it will jump when plugged in. Round Shen.

1. Check whether the exhaust valve is installed when cooking, if it is not properly deflated in advance, it will jump to automatic insulation, and the unplugged exhaust valve can be re-installed. Second, the rice cooker is most likely to be kept warm in advance, or the cavity code temperature sensition which magnet is aging, or the connection between the switch and the magnet is deformed, and there is no thermistor in the rice cooker, if the rice is cooked.

Hello, the rice cooker skips when the rice is not cooked, there may be the following reasons:1The internal temperature of the rice cooker is too high:

If the internal temperature of the rice cooker is too high, the built-in temperature preservation device will be triggered, which will cause the rice cooker to automatically trip and stop working, preventing the rice cooker from overheating and causing failure. This condition is generally caused by excessive electricity consumption, overheating inside the rice cooker, overheating at the bottom, etc. 2.

Insufficient water or too much rice: Insufficient water or too much rice will cause the rice cooker to not cook normally, because the rice cooker controls the heating by sensing the temperature change of the water, if the water is insufficient or the amount of rice is too much, it will cause the rice cooker to not heat normally, so that the rice cooker is not cooked. 3.

Damage to the inside of the rice cooker: If there is damage to the inside of the rice cooker, such as a short circuit in the heating pipe or a faulty control circuit, it can also cause the rice to be undercooked or the rice cooker to trip. 4.

Poor water quality: Cooking rice with poor water quality may cause the rice cooker to scale, which in turn will affect the heating effect and cause the rice to be undercooked. In order to avoid the above problems, we can pay attention to the following points:

Before using the rice cooker, put in the right amount of water to evaporate the evaporated water in the pot to ensure that there is enough water. When cooking rice, try to avoid adding too much rice, otherwise the rice will be too much and undercooked. In addition, in order to prevent the inside of the rice cooker from scaling, you can use vinegar water to clean it regularly to ensure the normal operation of the rice cooker.

Hello, rice cooker cooking rice is undercooked and tripping usually has the following possible reasons:1Rice cooker power issue:

The power supply is unstable or the voltage is insufficient, causing the rice cooker to not function properly. 2.Rice Cooker Internal Problems:

Components such as the temperature control circuitry, heater, or sensor of the rice cooker are malfunctioning or damaged, preventing the rice from cooking properly. 3.The question of the ratio of water and rice:

If the ratio of rice to water is incorrect, or if you do not add water and rice according to the capacity of the rice cooker, it may result in undercooked or overcooked rice. 4.Improper operation:

For example, not following the instructions of the rice cooker, or opening the lid during the cooking process, etc., will affect the cooking effect of the rice cooker. If the rice cooker is undercooked and trips, you can check the problems in the above aspects first, and then repair or adjust it after finding the problem. If there is no problem with the above Liangguo, it is recommended to send Yuxiang to a professional after-sales service center for maintenance.
