What is the power consumption of the induction cooker?
The power consumption of an induction cooker is related to the power used. Generally, the power consumption of a 1000 watt induction cooker is about 1 degree per hour. The 2100 watt induction cooker shows that the power of the induction cooker is 2100 watts, which means that it consumes 2100 watts per hour, which means that it consumes 2100 watt-hours of electricity for 1 hour. The induction cooker uses the principle of electromagnetic induction to achieve heating. It uses an alternating current to pass through the coil to generate an alternating magnetic field that changes its direction. An eddy current is generated inside the conductor in the alternating magnetic field. This is the vortex electric field that drives the conductor. Caused by the movement of medium carriers. The Joule effect of the eddy current will increase the temperature of the conductor, thereby achieving heating.
What are the reasons why the induction cooker is energized and not heated?
- The induction cooker itself fails, or the protection circuit is triggered due to changes in external natural factors and various sudden abnormal phenomena inside the machine.
- When the external voltage exceeds the operating voltage range of the induction cooker, the grid voltage protection will appear; when the temperature is 90 to 95 degrees, the internal overheat protection of the induction cooker will appear.
- When the grid is outdated and has poor contact, short circuit protection may occur.
- When the IGBT collector voltage rises and reaches the protection trigger condition, IGBT overvoltage protection is triggered; when the IGBT current is too high and reaches the trigger condition, IGBT overcurrent protection occurs.
What are the requirements for the pot of the induction cooker?
- There are several types of pots suitable for induction cookers, namely: enamel pots, cast pots, and stainless iron pots. At the same time, it should be noted that the diameter of the bottom of the pot is at least 8 cm. When the smaller diameter of the pot is less than 8 Cm, the induction cooker cannot work. Also, since the diameter of the magnetic field of the heating coil is 2226 cm, the pots and utensils in this magnetic field are more suitable.
- The ideal special pot for an induction cooker is mainly made of iron or steel products, because this type of ferromagnetic material will match the heating load during the heating process with the induced eddy current and convert energy, so relatively speaking, the magnetic field leaks less.
Power consumption of common household appliances
The power of household appliances is mostly in watts (w), and the power consumption is calculated in “degrees”, that is, one kilowatt of electricity consumed in one hour is one degree.
TV: Generally, the power of a 14-inch black-and-white TV is 40w, and the power consumption is one degree after 25 hours of use. The 18-inch color TV has a power of 75w, and consumes one kWh of electricity for 13.3 hours.
Radio and tape recorder: General portable dual-speaker radio and tape recorder has a power of 12w, and consumes one kilowatt hour of electricity after 84 hours of use.
Electric rice cooker: generally 500w, consumes one degree of electricity for 2 hours.
Electric iron: The general power is 30w, if used for 3.3 hours, it consumes one degree of electricity.
Washing machine: The general power is 250w, and the power consumption is once for 4 hours.
Electric fan: Generally, the power of a 14-inch fan is 50w, and the power consumption is once for 20 hours.
Refrigerator: Generally, a 100-liter refrigerator is 100W, which consumes an average of one kilowatt hour every 24 hours.
