How to Repair a Pressure Cooker Rice Cooker, How to Repair a Rice Cooker

Everyone is familiar with pressure cookers, but many people don't know how to repair pressure cookers, and today I will introduce some pressure cooker maintenance methods: 1It is difficult to close the lid of the electric pressure cooker, the sealing ring is not placed, and the sealing ring is replaced; Or the float jams the pusher, and gently pushes the rod with your hand to make the float fall; It may also be that the lid and body of the pot are deformed, and the lid and body of the pot need to be repaired or replaced for the electric pressure cooker; If the self-sustaining valve does not fall, use a sharp object to make the self-locking valve.

2.It is difficult to open the lid of the electric pressure cooker, if the float does not fall after deflation, use chopsticks to gently press the float valve; If the lid and pot body are deformed, the electric pressure cooker lid and pot body need to be repaired or replaced. 3.

The electric pressure cooker float cannot rise, and the float valve sealing ring is not placed, and the float valve sealing ring is placed; Air leakage around the lid, check the lid and the sealing ring of the lid; If the lid seal is not placed, put the lid seal; If the float valve is broken, replace the float valve. 4.If the float of the electric pressure cooker is up and there is air leakage, if the float seal is glued with food, it will also cause air leakage, and the seal needs to be cleaned; The float seal is worn out, and the float seal is replaced; The float valve is not tightened, tighten the float valve.

5.The lid of the electric pressure cooker is leaking, and the sealing ring of the lid is not placed, and the sealing ring is put on; If the lid is not closed, the lid is closed; The sealing ring is glued with food residue, and the sealing ring is cleaned; The sealing ring is worn, and the sealing ring is replaced; Deformation of the lid and pot body will also lead to air leakage, and the lid and pot body need to be repaired or replaced; If the inner pot is deformed, the inner pot needs to be replaced. 6.

The pressure limiting release valve of the electric pressure cooker is leaking, and the exhaust pipe is worn, replace the exhaust pipe; If the thimble of the pressure limiting release valve is damaged, replace the thimble; Cover the pressure limiting air release valve exhaust, replace the pressure limiting air release valve; The pressure of the pot itself is too high, the pressure switch fails, and the pressure switch is replaced; The exhaust pipe screw is tightened, tighten the screw. 7.The electric pressure cooker pressure limiting air release valve exhausts, the controller fails, so that the pot is continuously heated to reach 100kpa exhaust pressure limit, overhaul the display board and power supply board, replace or repair; If the food and water are too small, when the power is off to control the working pressure, the pressure in the pot will be rushed up to 100kpa, the pressure switch will be repaired, and the pressure switch will be debugged or replaced; The pressure switch starts to control the pressure of ultra-high boiling dry or burnt food, overhauls the pressure switch, and debugs or replaces the pressure switch.

8.The electric pressure cooker cannot be transferred to the state of heat preservation during the working process, and the display board is damaged, and the display board is replaced; If the indicator light is damaged, replace the indicator light on the display board. That's all for today, if you find a question that is not introduced above, you can search for it, I'm glad to answer it for you.

No matter what you repair, you must first figure out how it works.

1. Heating plate:

This is the main heating element of the rice cooker. This is an aluminum alloy disc with an electric heating element embedded in it, and the inner pot is placed on top of it, and you can see it when you remove the inner pot.

2. Temperature limiter:

It is also called magnetic. It is equipped with a permanent magnetic ring and a spring that can be pressed and positioned on the heating plate. When cooking rice, when pressing the rice cooking switch, the suction of the magnet drives the lever switch to keep the power contact on.

The suction weakens with the increase of temperature, when the water in the inner pot is evaporated, and the temperature at the bottom of the pot reaches 103 2C, the suction of the magnetic ring is less than the elastic force of the spring on it, and the temperature limiter is pushed down by the spring, driving the lever switch and cutting off the power supply.

3. Insulation switch:

Also known as a thermostat. It consists of a spring plate, a pair of normally closed contacts, a pair of normally open contacts, and a bimetal sheet. When cooking rice, the temperature inside the pot rises, and the two metal sheets that make up the bimetal sheet have different thermal expansion rates, resulting in the bimetal sheet bending upward.

When the temperature reaches more than 80C, driven by the upward bending bimetal sheet, the spring plate drives the normally open and normally closed contacts to convert, thereby cutting off the power supply of the heating element and stopping the heating. When the temperature in the pot drops below 80C, the bimetal sheet is gradually cooled and restored, and the normally open and normally closed contacts are switched again, and the heating element is connected to the power supply for heating. Repeatedly, the heat preservation effect is achieved.

4. Lever switch:

The switch is completely mechanical and has a normally open contact. When cooking, press this switch to connect the heating element to the power supply, and at the same time power the heating indicator to light it. When the meal is ready, the thermostat pops down and drives the lever switch to disconnect the contacts.

Thereafter, the heating element is controlled only by the insulation switch.

5. Current limiting resistor:

The appearance is golden yellow or white, the size is like a 3W resistor, which is pressed between the heating element and the power supply, which plays the role of protecting the heating element. Commonly used current limiting resistors are 185C 5A or 10A (depending on the power of the rice cooker). The current limiting resistor is a key element to protect the heating element, and it can be replaced by a wire.

The rice cooker is a more common cooking tool in the family, it is better than the original rice cooker, and it has been upgraded in all aspects, so there are more people who use the rice cooker, but no matter what it is, there will be problems after using it for a long time, thenRice cooker repairsWhat are the methods? What are the ways to choose a rice cooker? Let's introduce it to you together.

First, the method of rice cooker maintenance.

1.If water or rice soup enters the power socket of the rice cooker, it will cause a short circuit: in this case, you can scrub the inside of the socket and dry the water before continuing to use it.

The surface of the power socket or plug of the rice cooker is carbonized, in this case it is better to replace it with a new socket or plug. If the carbonization is not serious, it can be cleaned up, and it can also be used temporarily, but it can be replaced if there are conditions.

2.There will be a broken circuit in the power leads: Check the power leads with the ohmic stop of the multimeter.

The current-limiting resistor is blown off. This is more common. At this point, the resistor can be checked with a multimeter ohmic stop.

If the resistor is fused, it must be replaced with the current limiting resistor of the same model, and it should not be sloppy. The heating element in the heating plate is burned out. At this time, use the ohmic block of the Guesssen multimeter to check the heating element, if the circuit is broken, you can only replace the heating plate of the same model with a new one.

3.If you can't keep warm after cooking: This fault may be that the normally closed contact surface of the insulation switch is dirty or ablated, so that the contact resistance of the contact is too large, causing the contact to close and the circuit is not connected, the heating tube is not heated, and the rice cooker cannot be kept warm.

At this time, the contact surface can be cleaned with fine sandpaper and then coated with a layer of tin. If you still don't keep warm, you need to change the insulation switch.

Second, the selection skills of rice cookers.

1.The important thing to choose a rice cooker is the safety issue, when purchasing, you must check whether the product has the 3C logo, and the plug and power cord should also have this logo, and then check the product manual, the regular manual should be printed with the product name, trademark, rated voltage, frequency, power, manufacturer or seller, the manual is printed clearly, the manufacturer, address, **, maintenance items should be clearly marked, and should also be equipped with a warranty card, packing parts list, factory certificate, etc. In addition, it is necessary to check whether the power cord is double-insulated and whether the core is greater than or equal to the square millimeter.

2.It is also very important to choose the appearance of the rice cooker, observe whether the appearance is scratched or deformed from various angles, whether the joints of the parts are smooth, whether the coating of the inner tank is uniform, carefully check whether the inner tank coating will fall off, and the peeling coating may cause cancer. Forward carrying.

The electrical appliances in the kitchen are generally rice cookers in addition to the electric wok, which are two indispensable electrical appliances, so what are the maintenance methods of the rice cooker and what are the methods of its selection, I think everyone has also learned about the acres through the above introduction.

How to repair the rice pressure cooker if it is broken, hello, I am happy to answer the maintenance process for your hand canopy 1, cut off the power supply: the electric pressure cooker has a failure and can not continue to be used, you need to cut off the power supply, clean up the food and residue inside, and clean it up preliminarily. 2. Find out the cause of the failure

Before repairing, it is necessary to clarify the cause first, and then carry out targeted repairs. In order to avoid finding the wrong cause, you should investigate one by one to find out all the causes. 3. Repair according to the cause

If the leakage is replaced, the insulated edge material is replaced, and the metal parts are removed from the shell for insulation treatment; If there is air leakage, replace the pressure limiting valve, safety valve, safety plug sealing gasket, DAN spring and fusible sheet; If the exhaust is not smooth, clean up the foreign matter blocked in the safety valve or hole; If the rice is not cooked, check whether the bottom of the pot is deformed, or rotate it left and right to make close contact between the bottom of the pot and the heating plate.

Summary. 1. Deformation of the inner pot mouth Solution: Replace the inner pot 2. Failure of the inner pot cover, sealing ring, sealing fixing ring and other parts Solution:

Repair the lid of the inner pot, remove the hair-stripping of the sealing ring or replace the sealing ring. 3. Ball pad rupture or size deviation Solution: Replace the ball pad 4. Blockage of rice milk or foreign matter caused by exhaust.

1. Deformation of the inner pot mouth Solution: Replace the inner pot 2. Failure of the inner pot cover, sealing ring, sealing fixing ring and other parts Solution: Repair the inner pot cover, remove the sealing and fixing dry hidden ring hair, peel off the hall or change the sealing fixing ring in a more blind type.

3. Ball pad rupture or size deviation Solution: Replace the ball pad 4. Blockage of rice milk or foreign matter caused by exhaust.

Can you tell us more about that?

If the sealing ring is not placed, relocate the sealing ring; Or the float jams the pusher, and gently pushes the rod with your hand to make the float fall; It can also be regretted that the lid and body of the pot are deformed, and the electric pressure cooker needs to be repaired or replaced; If the self-sustaining valve does not fall, use a sharp object to make the self-locking valve. It is difficult to open the lid of an electric pressure cooker.

Hello is happy to answer for you, and the answer to your questions is as follows: The rice cooker is composed of three parts, the inner tank, the controller and the chassis. The inner liner is the core part of the rice cooker, which is generally made of aluminum or stainless steel, and the inner liner is responsible for the function of cooking food.

The controller is the control part of the rice cooker, which is generally composed of a temperature adjustment switch, a time adjustment switch, a temperature probe, etc., which automatically start and stop working according to the user's adjustment settings. The casing is the part of the rice cooker shell that is mainly used to assemble the inner tank and controller together, and is usually made of plastic or stainless steel materials. Rice cooker maintenance 1, check the wiring:

Check the wiring for defects, such as whether the connector is loose, whether the wiring is damaged, etc. 2. Check the temperature probe: Generally, the probe of the rice cooker is made of stainless steel, so it is necessary to regularly check whether the temperature probe is loose, percolation and other problems.

3. Check the power supply: check whether the power supply is normal, whether the power cord is damaged, whether the connector is loose, etc. 4. Clean the inner tank

Regularly clean the bucket and wash the inner liner to remove the oil and food residues that have accumulated in the air, so as to maintain the normal use of the rice cooker. 5. Operation test: After normal maintenance, operation test should be carried out to ensure the normal operation and performance of the rice cooker.
