Description
Technical Field
The invention relates to the field of electric cookers, in particular to an electric cooker with an automatic water level adjusting function.
Background
The electric cooker mainly comprises a heating plate, a temperature limiter, a heat preservation switch, a lever switch, a current limiting resistor, an indicator light, a socket and the like.
1. The heating plate is the main heating element of the electric cooker. The electric heating tube is embedded in the aluminum alloy disc, the inner pot is placed on the electric heating tube, and the inner pot can be seen after being taken down.
2. The temperature limiter is also called magnetic steel. A permanent magnetic ring and a spring are arranged in the heating plate, can be pressed and is positioned in the center of the heating plate. When the rice cooker is used, the lever switch is driven by the attraction of the magnetic steel to make the power supply contact keep on connection when the rice cooker is pressed down, the temperature of the pot bottom is continuously raised when the rice cooker is used, the attraction of the permanent magnetic ring is weakened along with the rise of the temperature, when the water in the inner pot is evaporated and the temperature of the pot bottom reaches 103 +/-2 ℃, the attraction of the magnetic ring is smaller than the elastic force of the spring on the magnetic ring, and the temperature limiter is pushed down by the spring to drive the lever switch to cut off the power supply.
3. The heat preservation switch is also called a thermostat. The device consists of a spring piece, a pair of normally closed contacts, a pair of normally open contacts and a bimetallic strip. When cooking, the temperature in the pot rises, and as a result, the bimetal bends upward due to the difference in thermal expansion and contraction rates between the two metal pieces constituting the bimetal. When the temperature reaches above 80 ℃, the spring piece drives the normally open contact and the normally closed contact to be switched under the pushing of the upwardly bent bimetallic strip, so that the power supply of the heating tube is cut off, and the heating is stopped. When the temperature in the pot is reduced to below 80 ℃, the bimetallic strip is gradually cooled and restored, the normally open contact and the normally closed contact are switched again, and the power supply of the heating tube is switched on for heating. The heat preservation effect can be achieved by repeating the steps.
4. The lever switch is completely of a mechanical structure and is provided with a normally open contact. When cooking, the switch is pressed to turn on the heating tube and the heating indicator light. When the meal is good, the temperature limiter bounces down to drive the lever switch to disconnect the contacts. After that, the heating tube is only controlled by the heat preservation switch.
5. The current-limiting resistor is golden yellow or white in appearance, is as large as a 3W resistor, and is pressed between the heating tube and a power supply to play a role in protecting the heating tube. The current limiting resistor is 185C 5A or 10A (based on the power of the electric cooker). The current limiting resistor is a key element for protecting the heating tube and cannot be replaced by a lead.
