What should I do if the electric pressure cooker can t open the lid

1. Rotate the lid clockwise with the problem of the stop opening valve, if the lid is moving, it means that there is no air pressure in the pot, and the pot cannot be opened because there is no return to the stop opening felling, preventing you from opening the lid. You can find a hard object (such as chopsticks) and press the check valve to bring the check valve back into place to open the lid. 2. There is still air pressure in the pot If you rotate the lid clockwise and do not move, it may be that there is still air pressure in the pot and it must be cooled and relieved.

Generally, it is natural cooling, wind cooling and lifting pressure felling. If you are not in a hurry to boil the pot, it is best to use natural cooling to relieve pressure, and there is generally no need to lift the pressure to relieve pressure until it is absolutely necessary. 3. If there are too many foreign objects attached to the lid and too many foreign objects are attached to the lid, the residues in the lid should be cleaned in time and often to ensure that the lid is clean.

Here's how an electric pressure cooker can't open the lid:1. The reason why the electric pressure cooker can't open the lid may be that the pressure is not completely relieved after the heating is completed, as long as you wait patiently and the pressure relief is completed, the problem can be solved. However, it should be noted that in this case, do not forcibly open the lid of the pot, otherwise the steam will spew out and it will be easy to hurt your hands.

2. a safety valve.

The increase in resistance between the electric pressure cooker and the lid may also lead to the failure to open the lid of the electric pressure cooker, because the electric pressure cooker is used for a long time, and the possibility of failure is high, even if the pressure drops to the normal value during use, the resistance between the safety valve and the lid is large, resulting in the safety valve can not be lowered to the normal position, this situation will also occur. When repairing, you can poke the safety valve with chopsticks to remove foreign objects, so that the gap is smaller, and the lid can be opened normally.

3. The lid of the electric pressure cooker cannot be opened, and the solution is to flush with cold water and use thermal expansion and contraction.

How to open the lid of the pot, or grasp the position on the lid with one hand, and grab the other side with the other hand to unscrew it vigorously, but finally wait for it to cool before operating.

4. If the check valve is not returned and cannot be opened, find a hard object and check the valve.

Press it once and the check valve can be opened.

The reason why the electric pressure cooker gas has been discharged and the lid still can't be opened:

1. There is no complete depressurization.

It may be that after the holiday, some pressure cooker outlets will be blocked at the end of the air vent, although they do not run out of gas in the morning, but in fact, the internal pressure is still very high.

2. The handle card owner.

Some pressure cookers with handle locks cannot be automatically retracted after a long time, and they are stuck and cannot be opened.

3. Excessive pressure.

Due to excessive pressure, the rubber ring is deformed and stuck between the lid and the pot, and the pressure is unloaded and cannot be opened.

4. The electric pressure cooker has been used for a long time.

Although the pressure has dropped to normal atmospheric pressure, the safety valve cannot naturally fall to the position where the lid can be opened normally due to the increased resistance between the safety valve and the lid (oil, food residues and oxides).

5. The pressure valve cannot be returned.

It may be that the pressure valve cannot be returned, you can poke it with a small tool, note that it must be completely deflated before it can be operated, and then carefully clean or repair the pressure valve after opening.

6. The air outlet hole is blocked.

It may be that the air outlet is blocked, so don't rush to open it at this time, you can use a damp cloth to cool down the temperature and try again.

If you don't have a complete decompression, just be patient and wait for it to be completely decompressed. If the electric pressure cooker is used for a long time, the pressure will drop to normal atmospheric pressure. However, due to the increased resistance between the safety valve and the lid (oil, food residue and oxides), it cannot naturally descend to a position where the lid can be opened normally.

If this is the case, you can poke the safety valve with the tip of the chopsticks, but pay attention to cleaning up the debris between the safety valve and the lid in time after use. Rinse with cold water until it can be opened. Find the (on-off) position on the lid with one hand, grasp the other side with one hand, and slowly press in the direction of opening, and it will open without damaging the pressure cooker.

Because there is air pressure, it needs to be deflated.

It may be that the steam is not finished, and you must finish the steam, otherwise you should be careful to blow up.

Although it is confirmed that the demand curve arises naturally from the theory of consumer choice, the derivation of the demand curve itself is not a theory that proposes consumer behavior. Simply determining how people react to change doesn't require a rigorous analytical framework. However, consumer choice theory is extremely useful.

As we will illustrate in the next section, we can use this theory to more deeply determine the factors that determine family behavior.

Instant Answer Draw budget constraint lines and indifference curves for Pepsi and pizza. Illustrate what happens to the budget constraint line and consumer optimum when pizza** rises. Use your graph to divide this change into income effects and substitution effects.

Four applications. Now that we've established the basic theory of consumer choice, we can now use it to illustrate four questions about how the economy works. However, since each problem involves family decision-making, we can address these issues with the consumer behavior model we just proposed.

Are all demand curves sloping to the bottom right?

In general, when an item** goes up, people buy less. Chapter 4 refers to this normal behavior as the law of demand. This pattern manifests itself in the demand curve sloping to the lower right.

However, as far as economic theory is concerned, the demand curve also sometimes slopes to the upper right. In other words, consumers sometimes defy the law of demand and buy more when one item rises. To illustrate how this can happen, look at Figure 21-12.

In this example, the consumer buys two items – meat and potatoes. Initially, the consumer budget constraint line was a straight line from A to B. The best advantage is c.

When the potato ** rises, the budget constraint line moves inward and is now a straight line from A to D. Now the best thing is e. It is important to note that the rise in potatoes has led consumers to buy more potatoes.

Summary. There are usually several possible reasons why the lid of an electric pressure cooker won't open:1

High internal pressure: During the cooking process, too high pressure will cause the safety valve to open to release part of the internal pressure, at this time, you need to turn off the power and wait for the pressure in the pot to be released slowly before you can open the lid. At this point, the safety valve or related button can be gently pressed to speed up the pressure release.

2.Stuck lock: When the electric pressure cooker is closed, it is fixed by the lock, if there is a problem with the lock mechanism and it is stuck, the lid will not be opened.

The electric pressure cooker is hermetically sealed by a seal, and if the seal is broken, the internal and external pressure cannot be effectively balanced, and it is difficult to open the lid at this time. The damaged seal needs to be replaced before it can be opened properly. 4.

Other mechanical failures: In addition to the above common reasons, the mechanical parts such as the bracket, torsion bar, and lid of the electric pressure cooker may also fail and cannot be opened, and the damaged mechanical parts need to be repaired or replaced before they can be opened. For the above situation, it is recommended that you take the following measures according to the specific situation:

1.Confirm that the power is turned off, wait at least 30-60 minutes for the internal pressure to be released, and then carefully try to open the lid. 2.

Inspect the locking mechanism to rule out jamming and replace damaged locking parts if necessary. 3.Inspect the seals and replace them if they are damaged.

There are usually several possible reasons why the lid of an electric pressure cooker won't open:1Internal pressure is too high:

During the cooking process, the pressure is too high, which will cause the safety valve to open to release part of the internal pressure, at this time, you need to turn off the power and wait for the pressure in the pot to be released slowly before opening the lid. At this point, the safety valve or related button can be gently pressed to speed up the pressure release. 2.

Stuck lock: When the electric pressure cooker is closed, it is fixed by the lock, if there is a problem with the locking mechanism, the lid will not be opened. It can only be opened after it has been repaired or replaced by opening the latch or related components.

3.Damaged seal: The electric pressure cooker is air-sealed through the seal, if the seal is damaged, the internal and external pressure will not be effectively balanced, and it is difficult to open the lid at this time.

The damaged seal needs to be replaced before it can be opened properly. 4.Other mechanical failures:

In addition to the above common reasons, the mechanical parts such as the bracket, torsion bar, and upper lid of the electric pressure cooker may also fail and cannot be opened, and the damaged mechanical parts need to be repaired or replaced before they can be opened. For the above situation, it is recommended that you take the following measures according to the specific situation:1

Confirm that the power is turned off, wait at least 30-60 minutes for the internal pressure to be released, and then carefully try to open the lid. 2.Inspect the latch to rule out jamming and replace the damaged latch parts if necessary.

3.Inspect the seals and replace them if they are damaged.

4.If none of the above methods work, you should contact the pressure cooker manufacturer or guess the maintenance spike judgment point for mechanical maintenance or overhaul. Do not use the force of the violent hall to open it early to avoid safety accidents.

At the same time, it is recommended that you regularly check the mechanical parts of the electric pressure cooker in daily use to ensure its normal operation and prevent failures.

If the lid of the electric pressure cooker cannot be opened, there are generally the following solutions: 1. If the pressure is not completely relieved, just wait patiently for the complete pressure relief.

2. The electric pressure cooker has been used for a long time, although the pressure has dropped to normal atmospheric pressure, but the safety valve can not naturally fall to the position where the lid can be opened normally due to the increase in resistance between the safety valve and the lid (oil, food residues and oxides).

3. Rinse with cold water until it can be opened.

4. Find the (on-off) position on the lid with one hand, grab the other side with one hand, and slowly exert force along the direction of opening, and then exert more force, it will open without damaging the pressure cooker.

The electric pressure cooker won't open the lid. Check whether the exhaust valve has fallen, if not, gently press the exhaust valve with chopsticks, let it vent, turn the upper cover, and it can be opened. If it can't be opened, pull the positioning rod (on the edge of the upper cover, stainless steel, will move) to open, which is the positioning rod screw is loose, tighten it.

Answer: Hello, the lid of the Midea electric pressure cooker needs to wait until all the steam in the pot is released and the air pressure inside and outside the pot is equal. At other times, the whole lid of the pot cannot be opened, and if it is forcibly opened, it is easy to steam splash, causing accidents such as scalding. Therefore, for personal safety, you must wait until the steam pressure inside and outside is equal, and there is no steam discharge from the air outlet before you can open the lid!

There is a safety switch on the handle of the pot, and after cooling, push the switch and turn the lid to the appropriate position, and it can be opened.

Hello de<>ar, there may be several reasons why the lid of the electric orange pressure cooker cannot be opened: 1The pressure is not fully released.

Before using an electric pressure cooker, first make sure that the pressure is fully released. Wait for the steam and air pressure in the pot to return to normal, then easily unscrew the lid. 2.

The lid notch is clogged. If too many ingredients are used or not washed thoroughly, it may cause the lid notch to become clogged and the lid cannot be opened. At this time, it is necessary to remove the dirt at the junction between the base of the lid bush and the body of the pot.

3.Aging of airtight rubber rings. The airtight rubber ring is an important part to keep the air tight in the pot.

If the airtight rubber ring is old or damaged, it may cause the lid to not open. At this point, it is necessary to replace it with a new airtight rubber ring. 4.

The electric pressure cooker itself is malfunctioning. If none of the above solves the problem, it may be that the electric pressure cooker itself is faulty and needs to be repaired or replaced. It is recommended to check whether there is pressure in the pressure cooker first, and if it has been completely released, you can try to clean the lid notch, or replace the airtight ring.

If none of the above methods work, it is recommended to find a professional maintenance personnel for inspection and maintenance. At the same time, pay attention to safety when using an electric pressure cooker and follow the instructions for use.
