Why can t rice cookers keep warm? What happens when the rice cooker only keeps warm and doesn t boil

The heat preservation effect of the rice cooker in a short period of time is still okay, but after a long time, the effect will not be reflected, that is because although the heating plate is heated, and the heat preservation of the bimetal thermostat only stays in the range of more than 60 degrees, and it is impossible to keep the whole pot of rice warm, so the effect is not as good as the insulation bucket.

Because the water in the rice evaporates too much when keeping warm, the bottom of the pot will dry out for a long time, and the moisture of the rice will decrease, but it will be placed in a thermos bucket. There is no heat source, only hot steam, and the hot vapor does not lose and retains the moisture of the rice, so the effect of the insulated bucket is better than that of the rice cooker.

It may be broken, because under normal circumstances, when you start cooking, the inside of the rice cooker is at room temperature, when you press the light to cook the rice, the magnet in the middle of the rice cooker will absorb the lever that is warped up below, when the temperature reaches 105 degrees, the magnet will not have the function of absorbing iron, so release the lever, at this time, it should be connected to the insulation circuit, when due to internal reasons, it may not be connected, so it will not be able to achieve the insulation function, understand? It could be that this is the reason.

Rice cookers generally have a heat preservation function, and the situation you are talking about may be that the thermostat is broken, or the temperature controlled by the temperature is not up to your satisfaction. If you feel that the temperature is too low, you can find the home appliance maintenance department to debug the thermostat for you. Thermostats generally control temperatures between 60 and 80 degrees.

If you feel that the heat preservation temperature of the rice cooker is too low, you can ask the master who repairs the electrical appliances to help you adjust it, and if you feel that the insulated rice is not delicious (the taste is not good), you can cover the rice with a damp cloth when you need to keep it warm.

The upper class never cooks anymore, and that's what my family does.

Because the water evaporates too much when keeping warm.

Because you're not keeping warm rice pluter, is yours a pot? If the lid is like a pot, then it's not a pot, it can only be used as a pot, understand?

It may be that the thermostat is broken.

Because you're buying a rice cooker, not a rice cooker.

Because you're buying parallel goods.

Spending a little more money on a high-end electronic rice cooker will solve the problem.

This situation is likely to be due to the failure of the temperature control switch inside the rice cooker, because the temperature control switch has a heated electric shock, which is the heating electric shock that is damaged, resulting in the rice cooker has been in heat preservation mode, unable to heat and cook rice according to the key instructions, so please ask a professional master to replace the new temperature control switch of the same model in time.

When it comes to key switches, this situation is also likely to be a problem with damaged buttons, because the key control is damaged, resulting in the rice cooker not receiving the heating signal, at this time, it will always be kept warm, and there will be no other mode operation, in this case, it is recommended to carefully check the buttons of the rice cooker to see if it is damaged, and replace and repair it in time.

If it is not a problem with the temperature control switch, nor is it a case where the key switch is damaged, it is all good but the rice cooker has been kept warm and cannot heat the rice, so it may be that the heating tube inside the rice cooker is damaged, how to check, if there is a multimeter at home, you can use the multimeter to measure the resistance of the heating tube, if the measurement result shows that the measured value is 1, at this time it means that the internal short circuit, at this time, try to ask a professional master to replace the new heating tube.

: This situation is most likely due to the failure of the temperature control switch inside the rice cooker, because the temperature control switch has a heated electric shock, which is the heating electric shock that is damaged.

The rice cooker is on but it won't heat up Reason:

1. The reason why the rice cooker does not heat may be that the fuse resistor is burned out, and the fuse resistance of the rice cooker may be burned out because there are foreign objects on the bottom of the pot or the heating plate, so that the inner pot of the rice cooker can not be fully in contact with the heating plate, if the temperature of the heating plate is too high, it will cause the fuse resistor to burn out, but at the same time it protects the heating plate of the rice cooker, carefully check the foreign body at the bottom of the rice cooker or the foreign body on the heating plate, remove the foreign body and clean the bottom of the pot or the heating plate, and be careful not to throw off the fuse resistor. The bimetal sheet used to keep the heat of the rice cooker is accidentally adhered to the contacts, which is easy to cause the fuse to be burned out due to continuous heating, so pay attention to replacing the bimetal sheet.

2. If you do not pay attention to the use of the rice cooker, resulting in the deformation of the inner pot or the deformation of the heating plate, it will also cause the temperature to be too high, which will cause the insurance to be burned, if this is the case, you should carefully trim the deformed inner pot of the rice cooker to restore the original state, and the repaired inner pot can still be used, but the deformed heating plate cannot be used, and it should be replaced with a new one.

3. If the heating plate of the rice cooker is in an open state, the rice cooker will not be able to be heated, so it should be carefully inspected and repaired.

How Rice Cookers Work:

Place the inner pot of the food on the heating plate so that the bottom of it fits the soft magnet in the center of the heating plate. Press the key switch, and the permanent magnet under the soft magnet will rise to contact the soft magnet; At this time, the pot has not yet heated up, and the soft magnet is below the Curie temperature, which is ferromagnetic, and can be magnetized by the permanent magnet and held at a high point. The soft magnet at the high point position drives the internal lever action to connect the upper and lower contacts of the circuit, and the electric heating element is energized and heated, and the food in the pot is heated and heated.

When the temperature of the bottom of the inner pot reaches 103 2 (this is the Curie temperature of the soft magnet), the soft magnet immediately senses and loses its magnetism, and falls from the high point position under the joint action of gravity and internal spring, and thus drives the lever mechanism, so that the upper and lower contacts of the circuit are separated, the circuit is disconnected, and the electric heating element is no longer heated, so as to achieve the purpose of temperature limiting. However, at this time, the heating plate is still in a state of high heat, and its heat capacity is large, so it can continue to heat the food in the pot for a period of time until the food is cooked thoroughly. In order to keep the food at a suitable temperature, some rice cookers are also equipped with a low-power amplifier to control its operating temperature with a bimetal thermostat.

This one works in a variety of ways. Some insulation depends on the temperature control switch, and some are the insulation sheet strung on the main heating plate, analysis, the main disk is normal, and the lack of heating is likely to be caused by the inspection and replacement caused by the broken switch contact.

Summary. Hello, it is a pleasure to serve you. The reason for this may be :

There is dirt or oxidation in the contact of the heat insulation switch of the rice cooker, which will lead to poor contact and poor electrical contact, resulting in the rice cooker not being kept warm; Or the temperature control plate of the rice cooker is burned, etc., resulting in the rice cooker not keeping warm, etc. The rice cooker can not be kept warm, you can contact the product after-sales service for maintenance.

The rice cooker can only cook rice without keeping it warm.

Hello, it is a pleasure to serve you. The reasons may be: there is dirt or oxidation in the contact of the heat insulation switch of the rice cooker, which will lead to poor contact and poor electrical contact, resulting in the rice cooker not keeping warm; Or the temperature control plate of the rice cooker is burned, etc., resulting in the rice cooker not keeping warm, etc.

The rice cooker can not be kept warm, you can contact the product after-sales service for maintenance.

Solution: 1. When the independent thermal insulation electric heating element is broken and the thermal insulation function cannot be realized, the thermal insulation electric heating element of the same specification should be replaced. 2. The contact of the warmer is fatigue damaged, resulting in poor contact of the contact, and can not be opened and closed normally, at this time, the contact should be replaced 3, the contact of the warmer is damaged, when it is not serious, it can be polished with an abrasive cloth to keep it smooth, and the contact needs to be replaced or replaced together with the contact when it is serious.

4. If the bimetal sheet of the insulator is damaged, so that the contacts cannot be contacted, the bimetal sheet or the entire insulator should be replaced.

What's the deal with rice cooker not keeping warm?

I believe that every friend will use a rice cooker for cooking at home, but some friends have rice cookers at home that are not kept warm, what is going on?

1. What's going on with rice cookers not keeping warm.

1. The fault of non-insulation is mainly caused by the "temperature sensing switch" composed of bimetal sheets, energy storage springs, adjusting screws, etc. Because after the rice is cooked, the main circuit S1 is cut off, and the rice cooker enters the state of automatic moisturizing. However, due to the poor contact of the S2 contact of the "temperature sensory switch" of automatic heat preservation, or serious oxidation, it is impossible to connect the power supply of the electric heating plate circuit, and of course it is impossible to keep the rice warm within 65 °C.

For the poor contact of S2 contact, you can use 00 sandpaper to gently polish it to restore the moisturizing function.

2. The rice cooker can be heated to indicate that the power supply circuit and heating circuit of the stove are good, and the heat preservation can not be kept warm after tripping, then there is only one insulation element left, some of this element is a temperature control board, and some are a temperature sensing contact made of bimetal sheets, they will be connected to the power when the temperature is lower than 60 degrees, and disconnected at 63 degrees, so that the temperature is always maintained at about 60 degrees, if the heat preservation function of the rice cooker is not normal, it means that the problem lies in this heat preservation element. It is estimated that the line of the component is broken or the performance of the insulation element is broken, and this fault can be easily solved, which is to replace the insulation element. Check again whether the power cable is connected.

2. How to clean the rice cooker?

1. The rice cooker is mainly used for cooking rice, and the dirt at the bottom of the inner pot is mainly the scorched residue of the rice grains, and the paint of the shell of the rice cooker is also due to the overflow and corrosion of the high-temperature rice soup, which makes the paint of the shell fall off. Soup or rice grains can also get into the switch and safety device, causing malfunction. Therefore, it is necessary to clean the electric sheet metal cooker frequently.

2. If it is an aluminum inner pot, it can be soaked in hot water and then brushed. The inner pot will corrode and produce black spots due to the action of acid and alkali, which can be cleaned by wiping it with detergent powder or soaking it in vinegar overnight. General stains on the shell of the rice cooker can be cleaned with an aqueous solution of dish soap or laundry detergent.

When there is debris in the internal control part of the rice cooker, you can use a screwdriver to remove the bottom of the rice cooker, clean it with a knife, and then scrub it with anhydrous alcohol.

3. If the bottom of the rice cooker is coke, add a little water to the pot, the water overflows the coke surface a little, plug in the power supply, and wait for the scorched rice to bubble after the water boils.

3. How to maintain the rice cooker?

1. Before using the rice cooker, check whether there are other sundries or dirt in the electric heating plate, and clean it up in time.

2. After the inner liner of the rice cooker is cleaned, wipe the water around the inner liner with a cloth before putting it into the shell of the rice cooker.

3. After putting the inner pot into the shell, turn the inner tank several times to make the hot plate and the inner pot in close contact.

4. If you find that the inner tank is deformed, replace it with a new one in time, and never replace it with an ordinary aluminum pot.

5. When cooking food, remember to put in food and water first, and then turn on the power. Do not force the switch to affect the service life of the rice cooker.

6. Don't let the rice cooker collide with other items, don't disassemble the rice cooker casually, and don't put the rice cooker in a damp place.

In most cases, it is due to the failure of the magnetic thermostat of the rice cooker to keep warm.

When the water in the pot is boiled dry, the temperature of the pot wall will get higher and higher, and when the temperature rises to 103, the magnet in the magnetic thermostat will lose magnetism, and the switch will be automatically disconnected, indicating that the rice has been cooked, and the rice cooker will automatically enter the heat preservation stage. When the magnetic steel thermostat is aged, the temperature in the pot has not reached 103 2, the switch has been disconnected and entered the state of heat preservation, which will cause the phenomenon of sandwiching raw rice. But sometimes the magnetic steel thermostat's switch contact is not in good contact will also have the same fault phenomenon, as long as the magnetic steel thermostat is replaced, the fault should be solved.

The body of the rice cooker is not kept warm in the first place, it is heated by a small heating plate at the bottom, it should be that thing is broken, then it needs to be replaced.

It is a high-temperature aging circuit under the rice cooker, which needs to be repaired by a maintenance person, and the user can also replace it.

Before using the rice cooker, you should carefully read the product instruction manual, master its use methods and essentials, and wash the rice directly with the inner pot to avoid collision, causing deformation of the bottom of the pot and affecting the use.

The bottom of your pot is uneven! It should have a radian! If you press the light when you cook rice, will it be hot?

If you can cook good rice, it means that most of the pot is good! That's the indicator light! If the cooking light is not heated, it may be that the heating plate is broken!

Or there is a problem with the temperature control and wiring in the pot! Need to take it to a repair shop to get it repaired! Do not disassemble yourself and be careful of electric shock!! Thank you.

It is recommended to buy Joyoung rice cookers, and professional ones are good.

Personally, I like the lining of Joyoung rice cooker, which is better than the general brand, and the rice made is also delicious. The Joyoung rice cooker we use at home is good, affordable, and durable.

Check whether the time adjustment button (thermostat) is not in good contact, if the heating indicator light is on during the adjustment of cooking, there should be no problem, otherwise the heater is burned out and needs to be replaced.

I have encountered too many such problems, it is very simple to open the low lid, when pressing the rice cooker switch, there are two copper contacts that cannot be touched, adjust it so that it can be touched, and let go of the rice cooker switch to see if it is separated, not separated and not good, it will burn the rice and smoke.

Press the button of the rice cooker, and the lever inside will turn on the tact switch, and the rice cooker will start cooking. You can't cook rice, maybe the touch switch is broken, just change it.
