How much is the electricity charge for the rice cooker? Don't worry about the electricity bill | my navigation news, my navigation news, my navigation.

First of all, let us understand the problem of electricity tariff in detail from the method of calculation.

Calculation method of electricity charge

Explain the calculation method of electricity tariff, including the explanation of indispensable terms in electricity tariff calculation. The electricity bill can be determined by any of the following formulas.

In addition, the "electricity charge per 1kWh" in this report is calculated using the "27 yen" expressed by the National Household Electrical products Fair Trade Agreement as the "new standard unit price".

The electricity charge for rice cookers varies depending on cooking and heat preservation.

The electricity bill is different when cooking and keeping warm. Let's calculate how much electricity will actually be spent on cooking. Here, take the imprinted IH rice cooker "NP-VN10" as an example to calculate.

Power consumption for each cooking: 143Wh/ times

Electricity charge per time: 143Wh x 27 yen / kWh= about 3.8yen

The electricity charge for one cooking is "about 3.8 yen". However, even if it is the same IH rice cooker, if it is a liter of cooking utensils, the electricity consumption during cooking will be 191Wh/ times, so it is only natural that the electricity bill of the cauldron will become higher.

The electricity charge for heat preservation is as follows.

Power consumption per hour of heat preservation: 15Wh/h

Every 10 hours: 15Wh/h × 10h × 27 yen / kWf= about 4.0yen

About 10 hours of heat preservation costs "about 4 yen" for electricity. Thus it can be seen that thermal insulation costs electricity unexpectedly. For those who want to control the electricity bill, it is best to minimize the time spent using the thermal insulation function.

How much does it cost for other cooking methods?

The electricity charge of the rice cooker is introduced above. what is the price if you cook by other methods? I calculated it as a reference.

Some people say that the rice cooked in a casserole is so delicious that it won't come back after cooking once. Gas is used in the casserole. Let's calculate the gas charge.

If you use the standard 20-minute medium heat for cooking in a casserole, it will incur a gas bill of about 18 yen.

In addition, this is the cost of using city gas. If it is propane gas, the price is 2 times or even higher than city gas. Considering the cost, rice cookers are cheaper.

Microwave rice cookers are sold by various manufacturers, including plastic, silicon and casseroles.

In a plastic microwave rice cooker, cooking costs about 10 yen. Microwave ovens and rice cookers are different, according to the cost of a rice cooker will be different, but it can also be said that the cost of rice cookers is cheaper.

Power-saving method of rice cooker

Rice cookers are household appliances that can foresee great power-saving effects. If there is anything that can be done from what is introduced now, please practice it.

As long as you reconsider the holding time, you can see a considerable power-saving effect. I always think that some people will keep warm all the time, but please cut off the heat preservation consciously and first try to shorten the heat preservation time by only one hour. If the original heat preservation function is used for a long time, it will also become the cause of rice discoloration and curing.

Rice cookers consume the most electricity when cooking. Therefore, minimizing the frequency of cooking will lead to energy savings and cheaper electricity bills.

However, even if we cook together, it is pointless to keep it warm for a long time. The rest of the rice should be kept in the freezer and heated in the microwave when eating.

People who are not delicious with frozen rice will also make efforts in such aspects as "wrap it in plastic wrap with steam and put it in the refrigerator", "flat plastic wrap to prevent uneven heating in microwave ovens", "use special containers for freezing" and so on. You can eat plump and delicious rice.

Home appliances sometimes consume electricity instead of standby power. If you unplug the socket, you don't have to wait for the electricity bill. The standby power of the rice cooker is about 0.3 yen to 0.7 yen per day. It can be reduced by about two yen a week.

People with ecological rice cookers will consume less electricity if they use the ecological model. Although the feeling varies from person to person, the taste will not change so much. When you want to save electricity, basically set up an ecological model. Please check what you have.

Today's rice cookers are more energy-efficient than they were 10 years ago. According to the energy-saving catalogue of the Environment Agency, the annual electricity consumption of the latest rice cooker is also different from that of the rice cooker of 10 years ago, "about 7kWh". The use of deteriorated food will damage the flavor and smell of rice, so change it regularly.

***

This time, the electric rice cooker is a very convenient tool for eating delicious rice every day, but if you use the heat preservation function for a long time and cook several times a day, the electric rice will become more expensive.

The trick to using rice cookers skillfully is to use them in combination with freezers, microwave ovens and other household appliances in addition to the situations where rice cookers are necessary.

For example, keeping warm for a long time is not only expensive for electricity, but also reduces the taste of food. However, freezing without heat preservation and heating in the microwave oven when you want to eat can not only make the electricity cheaper, but also make the rice taste better.

In order to use rice cookers more environmentally, think of ways to use them cleverly.
