Electric Rice Cookers

 

Target Scope


Electric rice cookers, except the following:

1) ones for industrial use,

2) ones without electronic circuits, or

3) ones whose maximum cooking capacity is less than 0.54 liters.

 

Energy Consumption Efficiency


Energy consumption efficiency shall be annual energy consumption (kWh/year) obtained as follows. Energy consumption is first measured for each of rice-cooking, keep-warm, timer and standby modes, and each value is multiplied by a coefficient based on the state of usage such as the number of cooking operation carried out per year, and then the resulting values are added together.

 

Categories & Target Standard Values


In the target fiscal year and each subsequent fiscal year, for each category, the weighted average value obtained by weighting energy consumption efficiency with shipment volume shall not be above the target standard value which is a weighted average value obtained by weighting standard energy consumption efficiency*1 with shipment volume.

*1: Values obtained from the standard energy consumption efficiency calculation formulas.

Category Standard energy consumption efficiency calculation formula
Heating method Maximum rice cooking capacity Category name
Electromagnetic induction heating products 0.54 liters or more, and less than 0.99 liters A EK=0.209M+48.5
0.99 liters or more, and less than 1.44 liters B EK=0.244M+83.2
1.44 liters or more, and less than 1.80 liters C EK=0.280M+132
1.80 liters or more D EK=0.252M+132
Non-electromagnetic induction heating products 0.54 liters or more, and less than 0.99 liters E EK=0.209M+36.7
0.99 liters or more, and less than 1.44 liters F EK=0.244M+75.6
1.44 liters or more, and less than 1.80 liters G EK=0.280M+99.0
1.80 liters or more H EK=0.252M+122
Remarks:
  1. The maximum rice cooking capacity shall be determined by multiplying the volume of the measuring cup specified by the manufacturer (unit: liter) by the maximum number of cups that the product is designed for.
  2. EK and M represent the following numerical values.
    EK: Standard energy consumption efficiency (unit: kWh per year)
    M: Mass of evaporated water (This is the mass of water expelled from the rice cooker when electric power consumption is measured for each rice cooking operation, and is the mean of the mass of the evaporated water obtained at every measurement of electric power consumption during cooking rice. The mass of water expelled from the rice cooker is calculated by subtracting the measured weight of the rice cooker within 1 minute after completion of cooking prior to opening the lid from the weight of the rice cooker containing water and rice prior to the start of cooking. It is expressed in grams and rounded off to 1 decimal place.)

 

Target Fiscal Year


FY2008 and each subsequent fiscal year

 

Energy Efficiency Improvement


Energy consumption efficiency was improved by about 16.7% compared with the FY2003 level in the target year (FY2008).
