1. Appointment means that you set the time, and it will take effect automatically when the time comes. For example, if you want to eat as soon as you get up in the morning, so that you can go to work, you just need to put the washed rice in, plug it in and set the time. The time setting is not according to the general clock, but according to the time difference.

For example, if you sleep at 10 at night and get up at 8: 00, you can figure out how many hours there are between 10 at night and 7: 00 tomorrow morning. Go to work at 7 o'clock, any time is fine. When it is done, it will automatically jump to keep warm, and you can eat it when you get up. Generally, pressure cookers with appointments are computer versions.

2. Timing means setting a certain time, that is to say, as long as you set it, it will burn, for example, press it for 30 minutes for half an hour, start working for half an hour after you press it, and jump to keep warm after half an hour.

For example, the holding time of chicken is 15 minutes, which means that the rice will be cooked in 15 minutes after the pressure is generated. If you think it's not done well, you can adjust it next time. Press the menu you need to do first, then press timing adjustment, and then press start.

Working principle of electric pressure cooker;

First, the realization of heat preservation function

When alternating current is connected to 220V (that is, the commercial power we often say), one end of the current passes through R2 resistor and insulation indicator lamp, and the other end passes through F fuse to the heating plate, thus forming a loop, the insulation indicator lamp lights up, and the heating wire heats up slightly to achieve insulation effect.

Second, the realization of cooking function

When alternating current 220V is connected, press the switch to realize conduction. One end of the current passes through the switch to the heating plate, and the other end passes through the F fuse to the heating plate, forming a loop. At the same time, the R 1 resistor and the cooking indicator are connected in parallel, and the cooking indicator will light up. Because this loop is not limited by resistance current, the heating wire will generate rated heat energy to achieve the purpose of cooking (or other ingredients). When the rice is cooked, the temperature of the electric heating wire exceeds the set value of the temperature control switch.

Third, the role of fuse in the circuit

When the current passing through the fuse exceeds its limit temperature, it will be immediately and permanently disconnected to protect other components (such as heating plates). If no fuse is installed, when the wrong voltage or internal short circuit is connected, the short circuit will catch fire due to the large mains voltage and current, which is easy to cause fire. At this time, the fuse is very important to ensure our life safety and property safety.
