How much is the electricity charge for the rice cooker per month?

How much is the electricity charge for the rice cooker?

Recent rice cookers are equipped with a variety of functions. According to heating methods, rice cookers can be divided into three types: "miniature rice cooker", "IH rice cooker" and "pressure IH rice cooker". Each rice cooker has the following characteristics.

Microcomputer rice cooker... The rice cooker with simple structure has weak firepower. Install a heater at the bottom of the inner pot and heat it to transfer heat to the entire inner pot and cook.

IH rice cooker... This is the rice cooker that has become the mainstream in recent years, with strong firepower. Using the "electromagnetic induction heating method" which heats the whole inner pot through the electromagnetic wire, the rice is heated and cooked at high temperature in one breath.

Pressure IH rice cooker... It is a rice cooker with multiple functions, and its firepower is stronger than IH rice cooker. After heating with "electromagnetic induction heating", the kettle is in a closed state and cooking under high pressure

The electricity charge of the rice cooker can be calculated as "electricity consumption (W) / 1000 × usage time (time) × electricity cost per 1kWh (yen / kWh)". The electricity consumption of rice cookers varies greatly when cooking and heat preservation. In addition, the electricity consumption varies according to the type of rice cookers. Therefore, for various types of rice cookers, the electricity charges for cooking and heat preservation are calculated.

In addition, use the rice cooker once a day, it takes 1 hour to cook and 5 hours to keep warm. The electricity charge per 1kWh is calculated at 27 yen.

"ZOJIRUSHI microcomputer rice cooker extreme cooking NL-DS10" 5.5.The power consumption of rice cooker for one cooking: 162W (cooking time is 1 hour) electricity consumption per hour of heat preservation: 16.8W

When cooking with this microcomputer rice cooker for one hour, the electricity charge is "162W / 1000 × 1 hour × 27 yen / kWh=4.374 yen". On the other hand, the electricity charge for 5 hours of heat preservation is "16.8W / 1000 × 5 hours × 27 yen / kWh=2.268". In other words, if you cook for five hours an hour and keep warm for five hours, the total electricity bill will be 6.642 yen. The electricity bill is about 206 yen a month.

"ZOJIRUSHI IH rice cooker extreme cooking NW-HA10" 5.5.The electricity consumption of rice cooker during one cooking (environmentally friendly cooking): 172W (cooking time is 1 hour) electricity consumption per hour of heat preservation: 15.1W

The electricity charge of the IH rice cooker for one cooking is "172W / 1000 × 1 hour × 27 yen / kWh=4.644 yen". The electricity charge for 5 hours of heat preservation is "15.1 W / 1000 × 5 hours × 27 yen / kWh=2.0385". The total amount of cooking and heat preservation is 6.6825 yen, which is about 207yen a month.

"TIGER pressure IH rice cooker < just cooking > JPA-X100" 5.5 combined rice cooker power consumption during one cooking (environmentally friendly cooking): 176W (cooking time is 1 hour) electricity consumption per hour of heat preservation (environmentally friendly cooking): 17.8W

The electricity charge for one cooking with this pressure IH rice cooker is "176W / 1000 × 1 hour × 27 yen / kWh=4.752 yen". The electricity charge for 5 hours of heat preservation is "17.8W / 1000 × 5 hours × 27 yen / kWh=2.403". The total amount of cooking and heat preservation is 7.155 yen. One month, it's about 222 yen.

Generally speaking, among the three types, the consumption of electricity in microcomputer rice cookers tends to become smaller. However, according to different models, we cannot generalize. Even for the models calculated this time, there is no great difference in electricity charges.

How to save the electricity cost of rice cookers

The rice cooker that I use every day. It doesn't cost much to cook and keep warm, but you can control the electricity bill with a little effort every day. Here are three ways to save the cost of rice cookers.

In an electric rice cooker, the longer it takes to keep warm, the higher the electricity bill. As a matter of fact, any type of rice cooker which has just calculated the electricity charge will use basically the same amount of electricity as that consumed in a cooking as long as it is kept warm for 10 hours.

In addition, according to the Energy Conservation performance Catalog 2020 of the Department of Resources and Energy, in order to save energy, the heat preservation time of rice cookers should be less than 4 hours. To minimize the holding time, please use the timer function. If you cook according to the mealtime, you can shorten the holding time and eat the delicious rice that has just been cooked.

"although the holding time can be very short, it is difficult to save on cooking." but recently, there are also rice cookers with energy-saving functions such as "environmentally friendly cooking mode". Using an environmentally friendly cooking model, delicious rice can be made while suppressing electricity.

To save electricity bills, reducing the frequency of cooking is also the key. For example, if you cook both in the morning and in the evening, it is more economical to cook two at a time. The cooked rice should be kept in the refrigerator or freezer and reheated in the microwave before eating.

However, in the case of 4-5 people, the number of people will increase if they are reheated in the microwave oven. According to the amount of rice, use the heat preservation of the rice cooker and the microwave oven well.

Develop ways to economize.

In families who cook their own meals, rice cookers are used very frequently. Because it is often used, the more you work on it, the more economical you will be. In addition, not only rice cookers, unplugging unused household appliances, etc., with a little habit can save waste.
