Introduction: Among many kitchen appliances, induction cooker and electric hot pot are two kinds of heating equipment commonly used in many families.
They all use electric energy for heating, but is there a difference in the energy-saving effect? This article will answer in detail which is more energy-saving, induction cooker or electric hot pot, from the aspects of experimental data and principle analysis.
1. Comparison of experimental data
In order to verify the power-saving effect of induction cooker and electric hot pot, we conducted an experiment.
Turn both devices to 1300 watts, heat the same volume of water, see which device boils first, and record the power consumption.
The experimental results show that the induction cooker boils water within 12 minutes and consumes 0.27 kWh of electricity, while the electric hot pot takes 21 minutes to boil water and consumes 0.38 kWh.
From this experiment, it can be seen that the power-saving effect of induction cooker is more obvious.
Second, the principle analysis
1. The principle of power saving of induction cooker
Induction cookers use the principle of electromagnetic induction for heating, and an electric current generates a magnetic field in the coil, and the magnetic field lines in the magnetic field pass through the bottom of the pan, generating eddy currents to heat the food.
The heating speed of the induction cooker is fast, the thermal efficiency is high, and the heat conversion rate can reach more than 90%.
Therefore, the power consumption of the induction cooker is relatively low in the same amount of time.
2. The principle of electric hot pot power saving
The heating principle of an electric hot pot is similar to that of an induction cooker, but its thermal efficiency is relatively low.
Electric hot pots usually use stepless speed regulation, and the temperature is controlled by humans.
During the heating process, heat is easily dissipated into the air, resulting in a decrease in thermal efficiency.
The pot body of the electric hot pot is not easy to separate from the heating plate, and there will be a certain loss in the process of heat transfer, which will affect the power-saving effect.
3. Scenarios and suggestions
1. Usage scenarios
Induction cooker is suitable for a variety of cooking methods, such as stir-frying, stewing, frying, frying, etc., and has more comprehensive functions.
The electric hot pot is mainly used for hot pot, barbecue and other occasions, and the function is relatively simple.
2. Purchase recommendations
(1) From the perspective of power saving, induction cooker has more advantages and is suitable for long-term use.
(2) If the family often eats hot pot, you can choose electric hot pot, but try to choose split electric hot pot, because its electric heat conversion rate is relatively high, and the power saving effect is better.
(3) In terms of price, electric hot pot is relatively cheap, if you have a limited budget, you can consider buying electric hot pot.
Fourth, summary
Induction cookers have obvious advantages in terms of power saving, high thermal efficiency, fast heating speed, and are suitable for a variety of cooking methods.
Electric hot pot is more convenient to use in specific occasions (such as hot pot), but the power-saving effect is slightly inferior to that of induction cooker.
When purchasing, consumers can choose the right kitchen appliances according to their needs and budget.
