Dishwasher performance standards are being revised

“At present, more and more consumers have begun to pay attention to household dishwashers, and the technical level of this product has also been greatly improved than before. However, the dishwasher performance standards are too old and it is still 20 years ago. QB1520-1992 “Electrical Dishwasher for Household and Similar Uses” was formulated.” Lu Jianguo, Secretary-General of the National Household Electrical Appliances Standardization Technical Committee Cleaning Appliances Subcommittee, revealed that “the newly revised standards are in the process of being formulated and are currently approved for approval by the end of this year. Or will be officially released."

As early as the end of 2010, at the beginning of the drafting of the Working Group on the Drafting of “Standard for Electric Dishwashers for Household and Similar Uses”, the National Committee for the Standardization of Household Appliances Cleaning Tools Subcommittee on Technical Standards No. 2010-2721 T-QB requested that Many dishwasher companies are actively joining.

In the list of members of the drafting group that the “Electrical” reporter got, it is almost possible to see all the well-known dishwasher companies in the country.

“The members of the standard drafting group include domestic household dishwasher inspection agencies and major manufacturers. The total annual output of these companies exceeds 85% of the national total output, which can fully represent the current mainstream technological development direction of household dishwashers in the domestic and international markets. "Lu Jianguo is very pleased." This also reflects from the side that the dishwasher company wants to push the industry's development.

First, increase the sterilization content and other new content "As the revised standard of QB1520-1992, "Household and similar use of electric dishwasher" added many new content." Panasonic Home Appliances Research and Development (Hangzhou) Co., Ltd. Technology Foreign Minister Jia Chungeng The reporter told reporters that the new additions to the standard include: Revised definitions and standards for the use of electric dishwashers for household and similar purposes; Added terminology and definitions for cleanliness index, drying index, energy efficiency index, water Efficiency index and other content and corresponding evaluation methods. The most important change in standards is the addition of functional indicators such as “standby power,” “power-off,” and “sterilization rate.”

"Electrical" reporter in the "home and similar use of electric dishwasher" approval of the draft found that the criteria for sterilization rate and antibacterial rate requirements are: the product clearly has a sterilization function of the dishwasher sterilization rate should not be less than 99%, antibacterial function of the dishwasher antibacterial rate should not be less than 90%, does not claim that the sterilization or antibacterial function of the dishwasher does not apply this requirement. In addition, Appendix B of the normative norm has also developed a sterilization test method for dishwashers.

This content is the product of the drafting group's integration of foreign advanced standards in the standard revision process. “The European dishwasher standard currently has no provisions on sterilization and antibacterial content, which has already been included in the US standard. We will have separate standards for the “Household and similar electric dishwashers”. The essence has been drawn from and has not completely copied a certain standard," said Lu Jianguo.

Fang Lei, manager of dishwasher products at Bosch Electric Appliances (China) Co., Ltd., introduced to reporters that standby power and shutdown power are important indicators for examining the annual power consumption of dishwashers. The standard defines this content as follows: The standby power of the dishwasher in the product control section with the status display should be no more than 1W, the standby power without the status display should be no more than 0.5W, and the power of the dishwasher should not exceed 0.5W.

In addition to these two indicators, the reporter also saw in the standard approval manuscript the requirement for deviation of the product's express value. Specific requirements are: In the test conditions specified in this standard, the dishwasher's clean index, drying index, energy efficiency index and other measured values ​​and their deviations in the product or instructions for use should not exceed the deviation shown in Table 1.

Second, the original indicators require a substantial increase "Although it is revised standards, but the new version of "household and similar use of electric dishwasher" is equivalent to re-enactment, the indicator is very different from the old version." Foshan City, Shunde District, the United States washing electrical manufacturing limited Liang Hongyi, a senior engineer of the company, told the “Electrical” reporter that the new standard adjusted several dishwasher indicators that Chinese consumers are generally concerned about, including cleanliness index, water efficiency index, noise, and trouble-free running time.

The reporter also saw in the standard preparation notes that the drafting group believed that the Chinese dishwasher industry standard QB 1520-1992 was no longer suitable for the development status and trend of the domestic household dishwasher industry. Therefore, in the process of revision of the standard, the standard revision working group fully considered the development of dishwashers over the past decade and the impact on product technical requirements and parameters, especially considering the energy saving and The water performance is based on the relevant technical parameters of domestic and international standards for similar products, and this standard is revised in light of the actual development of Chinese products and industries.

For the main performance parameters of the dishwasher, the newly revised standard has made a series of adjustments, including the dishwasher cleanness index should not be less than 0.76, the dryness index should not be less than 0.55, the energy efficiency index should not be greater than 89, water efficiency index should not Above 81, the sound power level noise during dishwasher washing and drying should not exceed 58 dB(A) and the accumulated trouble free operation cycle of the dishwasher should not be less than 1960.

“The current indicator requirements are several times higher than before, which shows that our technical level can already be in line with international standards. The revision of these indicators will help consumers re-recognize the dishwasher. If the original standard is adopted, this product will cost water. It also cost electricity.” Lu Jianguo told reporters that the current domestic household dishwasher manufacturers more than 10, the annual output of more than 8 million units, from the current development situation, the industry has great potential. For the future transformation of the dishwasher industry and product upgrading, the revision of the standard will play a positive role in promoting.

III. Classification of major performance indicators The reporter noticed that “Household and similar electric dishwashers” not only revised several important indicators such as cleanliness index, drying index, energy efficiency index, water efficiency index, noise, and trouble-free running time. The technical requirements and test methods, in the annex of the standard, also have a graded reference for these major performance indicators. For these six technical indicators, the standards are divided into four levels of A, B, C, and D according to the international advanced level, the domestic advanced level, and the domestic medium and general level, among which the A level is the highest (see Table 2).

According to Lin Jiaming, chief of the technical department of Zhongshan Galanz Daily Electric Co., Ltd., who participated in the standard revision work, the classification of major indicators provides a clearer reference for consumers to purchase dishwashers, so that consumers can know what kind of products they have. It is the best.

According to the reporter's understanding, the number of dishwashers that have reached the 6A requirement in China at present is not much. On July 10, 2011, the China Household Electrical Appliances Research Institute announced the results of the 6A inspection of dishwashers in 2011. Among the four companies, Galanz, Panasonic, Siemens and Midea have 7 product models. The test was conducted in accordance with the JDYB007-2011 “Classification of Household and Similar Purpose Dishwasher Performance Grading” published by the China Household Electrical Appliances Research Institute at the end of March 2011. The specifications of this technical specification are in line with the grading indicators in “Household and similar electric dishwashers”.

In this regard, Hongxiang Liang revealed to reporters that the current 6A products do not have technical difficulties for enterprises, but the cost will increase.
