Repair skills of electric pressure cooker 1. It is difficult to close the cover of electric pressure cooker
The sealing ring is not put properly, so relocate the sealing ring; Or the float catches the push rod and gently pushes the rod by hand to make the float fall; It is also possible that the lid and body of the electric pressure cooker are deformed and need to be repaired or replaced; If the self-locking valve does not fall, use a sharp object to make the self-locking valve.
2. It is difficult to open the cover of the electric pressure cooker
If the float does not fall after deflation, just gently press the float valve with chopsticks; If the cover and the pot body are deformed, the cover and the pot body of the electric pressure cooker need to be repaired or replaced.
3. The float of the electric pressure cooker cannot rise
The float valve sealing ring is not put, and the float valve sealing ring is put; Leakage around the pot cover, check the pot cover and the pot cover sealing ring; If the lid sealing ring is not put, put the lid sealing ring; If the float valve is broken, replace the float valve.
4. Air leakage after the float of the electric pressure cooker rises
If food sticks to the sealing ring of the float, it will also cause air leakage, so it is necessary to clean the sealing ring; The float sealing ring is worn, so replace the float sealing ring; The float valve is not tightened. Tighten the float valve.
5. The lid of the electric pressure cooker leaks air
The lid sealing ring is not put, and the sealing ring is put; Close the lid, close the lid; The sealing ring is stuck with food residue, so clean the sealing ring; The sealing ring is worn, so replace the sealing ring; The deformation of the cover and the pot body will also lead to air leakage, so it is necessary to repair or replace the cover and the pot body; If the inner pot is deformed, the inner pot needs to be replaced.
6. The pressure-limiting relief valve of the electric pressure cooker leaks
The exhaust pipe is worn, so replace it; The thimble of the pressure-limiting relief valve is damaged, so replace the thimble; Cover pressure relief valve exhaust, replace the pressure relief valve; If the pressure of the pot itself is too high and the pressure switch fails, replace the pressure switch; The exhaust pipe screw is tightened. Tighten the screw.
7. The controller of the pressure-limiting relief valve of the electric pressure cooker is out of order, so that the cooker can be heated continuously to reach the pressure limit of 1Kpa, and the display board and power board should be overhauled, replaced or maintained; There is too little food and water. When the working pressure is controlled to be cut off, the pressure in the pot rises to 1Kpa, and the pressure switch is overhauled, debugged or replaced. The pressure switch starts to control the pressure. If the food is overheated or burnt, repair the pressure switch, debug or replace the pressure switch.
8. The electric pressure cooker can't be turned into heat preservation state during working
If the display board is damaged, replace it; The indicator light is damaged. Replace the indicator light of the display panel.
the difference between a pressure cooker and an electric pressure cooker is that under normal atmospheric pressure, water can only be boiled to the boiling point of 1 degrees with an ordinary pot, and then even if it is heated again, the temperature of water will not be higher than the boiling point.
and the pressure cooker is used? Air pressure is proportional to the boiling point of water? The principle of (for example, on the plateau, the terrain is high and the air pressure is low. If you use an ordinary pot to boil water, it may boil at more than 8 degrees, indicating that the boiling point of water is also low where the air pressure is low. On the contrary, if the air pressure is increased, the boiling point of water will rise accordingly).
after the water in the pressure cooker is heated and boiled, it generates steam, and then the pressure of the steam will gradually increase. According to the principle that the pressure is directly proportional to the boiling point of water, the boiling point of the water in the pot is continuously increased, so the temperature in the pot will also increase, which can exceed 1 degrees. In this way, high temperature and high pressure can be used to cook food quickly or to sterilize. In principle, the electric pressure cooker and the pressure cooker are the same, but the heating methods are different. The electric pressure cooker will not produce open flames and burning waste gas during use, which is more energy-saving, environmentally friendly and safe than the pressure cooker. Electric pressure cooker can be used regularly, make appointments, adjust temperature and keep warm, which is more convenient than pressure cooker.
Precautions for maintenance of electric pressure cooker 1. The food put into the cooker should not exceed 4/5 of the capacity of the cooker, and the food put in should not be corrosive.
2. cover the lid and turn it clockwise to ensure that the handles are completely overlapped or sealed before turning on the power.
3. After the cover is closed, you can't add other weights to the pressure limiting valve, and you can't arbitrarily extend the cooked food to avoid accidents.
4. Before opening the lid, exhaust the air. If you don't exhaust the air, open the lid. The steam will easily burn people. Therefore, for your own safety, exhaust the steam and cool the pot before opening it.
5. When cooking porridge, when the pressure limiting valve is deflated and lifted, the pan should be immediately removed from the fire to prevent rice soup from being sprayed.
6. The exhaust hole is easily blocked by foreign objects, so it should be cleaned regularly, otherwise the exhaust is blocked and it is easy to break down.
7. Wash and dry it at any time after use, and store it in a cool, dry and ventilated place, away from fire sources and corrosive objects.
8. Alkali, salt, soy sauce, etc. should not be stored in the pot for a long time to prevent corrosion, nor can it be stored for a long time, otherwise a large number of bacteria will breed and odor will be emitted.
