Table 1 Several types of insulation type automatic pressure cooker model, specifications and technical parameters Model Rated power (w) Inner pot volume (L) Inner pot diameter (cm) Working pressure (KPa) Pressure limiting value (KPa) Safety pressure Currently on the market The newly introduced thermal insulation automatic pressure cooker (hereinafter referred to as automatic electric pressure cooker) is a new product integrating rice cookers, pressure cookers, and simmering pans. It has a novel shape, elegant appearance, time saving, and good thermal insulation performance. , clean and safe, easy to operate and so on. In addition to cooking rice, porridge, soup, but also stewed meat and risotto.
The structure of the automatic electric pressure cooker is as shown. It is mainly composed of outer pot, lid, inner pot, sealing ring, float valve, pressure limiting vent valve, electric heating plate, control box, pressure adjustment knob, button and indicator light.
- The pressure-relief valve body is composed of a double-layer structure, which not only reduces the surface temperature of the outer pot, but also achieves the effect of insulation and energy saving. The port is provided with a lock and can be matched with the lid, and the electric heating plate for the rice cooker is installed at the bottom, and the surface is coated with a non-stick layer to facilitate cleaning. The control box is equipped with pressure regulator knobs, buttons, and heating and thermal indicators.
The lid is also a plastic, stainless steel double structure with plastic handles on the surface. The opening and closing of the lid adopts the external rotation type automatic locking, dynamic sealing and elastic force control structure. The lid is provided with double safety protection devices. The float valve and the pressure limiting air release valve are installed on the lid surface. When the pressure in the boiler is too high and the pressure limit value is reached, the pressure limiting air release valve automatically exhausts and limits the pressure to ensure safe use. .
The inner pot is the same as the aluminum alloy inner pot used for the rice cooker. The inner wall has a scale line and the surface is coated with a non-stick layer, which is neither sticky to food nor easy to clean.
Second, the working principle of the circuit as shown. XP is a grounded three-pole tortoise plug, FU is an over-temperature protector, ST1 is a temperature limit switch, ST2 is a thermal switch, SP is a pressure regulator, Rl, R2 is a step-down resistor, and HL1 and HL2 are thermal indicators. And heating indicator, EH is electric heating plate. Connect XP to 220V AC power supply, and then adjust the SP to a certain pressure level. Press the button, the HL2 heating indicator lights up, EH starts heating, when the set pressure value is reached, the button is automatically reset, EH heating ends, HL2 goes out, HL1 lights up and automatically enters the holding state.
An over-temperature protector is set in the circuit. When the temperature in the pot is too high or there is a short-circuit fault, the FU is automatically blown to protect it.
The types, specifications and technical parameters of several types of automatic electric pressure cookers are shown in the table. Only when they are correctly used, the advantages and characteristics of the insulated automatic electric pressure cooker are displayed. The use method and sequence are as follows: Open the lid and hold the lid by hand, counterclockwise Rotate the lid to the alignment mark and lift the lid upwards.
Put the food out of the seal and the inner pot and put food and water in the inner pot. The food and water placed should not exceed four-fifths of the height of the inner pot, at least one-fifth of the height of the inner pot, and generally not more than three-fifths of the height of the inner pot (see the inner pot scale). .
Put the inner pot and the electric heating plate before putting the pot inside the pot. Place the inner pot and put it in contact with the electric heating plate. Place the sealing ring horizontally on the inner pot wall.

Rotate the lid clockwise until it locks. When you hear a “clickâ€, it means that the lid is locked.
The bonnet of the pressure relief vent valve is snapped onto the valve seat and the float of the float valve should be checked to fall.
Adjust the pressure according to the dung and nature of the food, turn the pressure switch knob to the proper gear. Table 2 shows the relationship between the cooking menu and the pressure setting.
Heating power on, press the button, "heating" indicator light, start cooking; wait for the button to automatically reset, "insulation" indicator light, indicating that people into the insulation state.
Before using the lid, heat must be used to keep warm for a while. Table 3 shows the relationship between cooking menu and holding time.
If you cook hard or hard-to-cook foods such as burdock, beans, etc., you must keep warm for 15 minutes before heating. Or extend the holding time more than 60 minutes.
If continuous insulation is required, it is not necessary to unplug the power plug. When the temperature of the food drops to the holding temperature, the “heating†indicator lights up automatically to indicate that it is reheated and automatically kept warm.
(4) Lift the lid to take food, first unplug the power plug, then turn the pressure regulating knob counter-clockwise to "low" gear, and then manually lift the bonnet of the pressure relief valve deflation.
If boiled liquid foods, according to the above insulation time insulation, it is not appropriate to immediately lift the bonnet of the pressure limiting vent valve, and should be carried out after the float of the natural cooling float valve falls, so as to avoid the liquid food ejected from the deflation tube.
After the deflation is completed, check that the float has actually fallen before opening the lid to take food.
The proper maintenance of the automatic electric pressure cooker not only reduces the malfunction but also prolongs the service life. The maintenance method is as follows: Before cleaning the automatic electric pressure cooker, it is necessary to turn off the power first, and it is prohibited to operate with the power.
When shifting and moving, it should be handled with care.
After each use, the inner pot food should be cleaned, and the inner pot should be cleaned with a sponge or a non-metallic soft brush, and then wiped with a noon cloth.
The lid's plastic cover is wiped with a soft cloth, not pounds of steel cover, anti-blocking cover, pressure relief valve, float valve, seal ring, etc., first rinse with clean water, and then wipe dry with a dry cloth.
The outer pan can be wiped and wiped with a damp cloth and some neutral detergent, and then wiped with a dry cloth. Do not immerse the entire outer pot in water or shower under the faucet.
In order to ensure the use of safety, the use of automatic electric pressure cooker must have a good grounding line.
It is forbidden to use automatic electric hot pot D in the environment of wet and flammable materials. D. Food and water should be in accordance with the instructions of the user's manual. Avoid excessive and too little.
