There are: Supor, Panasonic, Midea, Pentium, and Tiger.

1. Supor

Supor rice cooker is a cooking utensil that converts electric energy into internal energy. It is easy to use, clean and hygienic. It can also steam, boil, stew, simmer, etc. food. operating functions. Supor rice cooker uses electric energy to convert into internal energy. It is easy to use, clean and hygienic. It also has multiple operating functions such as steaming, boiling, stewing, and simmering food.

Common rice cookers are divided into three categories: automatic heat preservation type, timed heat preservation type, and new microcomputer-controlled type. Nowadays, it has become an everyday household appliance. The invention of the rice cooker has reduced the time many families spend cooking rice.

2. Panasonic

Panasonic rice cookers are cooking utensils that convert electrical energy into internal energy. They are easy to use, clean and hygienic, and can also be used to steam, boil, stew, and simmer food. Various operating functions.

3. Midea

Midea rice cookers are well-known among small household kitchen appliances. Its inner pot is particularly beautiful, stunning and eye-catching from the inside out. It's like a charming blue star inside, and it's golden outside. It feels like a golden cornucopia, full of nobility.

Midea’s power plug is built-in, safe and waterproof. It also has a handle, which is very convenient and stable to lift. The soup spoon and rice spoon also have user-friendly designs. The rice spoon can stand or lie down. There is a curved hook at the end of the soup spoon that can be hung on the edge of the bowl to prevent it from slipping into the soup.

4. Pentium

Pentium rice cooker is a perfect combination of modern technology and traditional cooking. The main representative products are earth stove pots, the first delicious pressure regulating valve, according to rice, soup / Different cooking modes such as porridge and steaming, free control of pressure, precision technology, achieving expert quality; 6MM ultra-thick cauldron bottom, retaining intelligent heat, and simmering the original flavor of rice.

5. Tiger brand

Tiger brand rice cooker, also known as Tiger brand electric cooker. It is a cooker that converts electrical energy into internal energy. It is easy to use, clean and hygienic, and has multiple operating functions such as steaming, boiling, stewing, and simmering food. Common rice cookers are divided into three types: automatic heat preservation type, timed heat preservation type, and new microcomputer-controlled type.

Now a daily household appliance in Asia, the invention of the Tiger rice cooker has reduced the time many families spend cooking. The world's first rice cooker was invented in the 1950s by Japanese company Ibuka's Tokyo Communications Engineering Company.

The working principle of the rice cooker

1. Heating plate

This is the main heating element of the rice cooker. It is an aluminum alloy disc embedded with an electric heating tube. The liner is placed on top and can be seen when the liner is removed.

2. Temperature limiter

Also called magnet. It comes with a permanent magnetic ring and a spring that presses against the center of the heating plate. During cooking, when the cooking switch is pressed, the lever switch is driven by the suction of the magnet to keep the power contacts connected.

When cooking rice, the temperature of the bottom of the pot continues to rise, and the suction force of the permanent magnet ring weakens as the temperature rises. When the water in the inner pot evaporates and the temperature of the bottom of the pot reaches 103±2℃, the suction force of the magnetic ring is less than the spring force on it, the temperature limiter is pressed down by the spring, and the lever switch is driven to cut off the power supply.

3. Thermal switch

Also called thermostat. It consists of a spring plate, a pair of normally closed contacts, a pair of normally open contacts and a bimetal plate. As it cooks, the temperature in the pot will rise. The bimetal plate bends upward due to the different thermal expansion rates of the two metal plates. When the temperature reaches above 80°C, the upwardly bent bimetal piece drives the spring piece to drive the normally open and normally closed contacts to change, cutting off the power supply to the heating tube and stopping heating.

When the temperature in the pot drops below 80°C, the bimetallic piece gradually cools down and recovers, the normally open contact and the normally closed contact switch again, and the heating tube power is turned on for heating. Repeat this to achieve the effect of heat preservation.

4. Lever switch

The switch is completely mechanical and has a normally open contact. When cooking, press this switch to turn on the heating pipe and at the same time supply power to the heating indicator light so that it lights up. When the meal is ready, the temperature limiter will pop up, actuating the lever switch and causing the contacts to open. After that, the heating tube is only controlled by the insulated switch.

5. Current-limiting resistor

Most of its appearance is golden yellow or white, and its size is like a 3W resistor. It is pressed between the heating tube and the power supply to protect the heating tube.

Common current limiting resistors are 185c5a or 10A (depending on the power of the cooker). The current limiting resistor is a key component for protecting the heating tube and is irreplaceable for the conductor.
