Microwave Ovens
Target Scope
Microwave ovens, except the following
1) ones having gas oven
2) ones for business use,
3) ones whose rated input voltage is exclusive to 200V,
4) ones whose internal height is less than 135 mm, or
5) ones that are incorporated into integrated kitchen systems and the like.
Energy Consumption Efficiency
Energy consumption efficiency shall be annual energy consumption (kWh/year) obtained as follows. Energy consumption is first measured for each of microwave function, oven range function and standby mode, and each value is multiplied by a coefficient based on the state of usage such as the number of heating 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 with shipment volume.
| Category | Standard energy consumption efficiency | |||
|---|---|---|---|---|
| Function | Heating method | Internal volume | Category name | |
| Microwave having no oven function (single-function microwave) | ― | ― | A | 60.1 |
| Microwave having oven function (oven ranges) | With exposed heater (excluding those that employ a hot air circulation heating method) | Less than 30 liters | B | 73.4 |
| 30 liters or more | C | 78.2 | ||
| Without exposed heater (excluding those that employ a hot air circulation heating method) | Less than 30 liters | D | 70.4 | |
| 30 liters or more | E | 79.6 | ||
| Employing a hot air circulation heating method | ― | F | 73.5 | |
| Remarks: | “Internal volume” refers to the numeric value calculated from the usable dimensions of the heating chamber defined by Electrical Machinery and Appliance Quality Labeling Regulations under the Household Goods Quality Labeling Law (Law No. 104 enacted in 1962). |
Target Fiscal Year
FY2008 and each subsequent fiscal year
Energy Efficiency Improvement
Energy consumption efficiency was improved by about 10.5% compared with the FY2004 level in the target year (FY2008).
