-Home appliances

Home appliances (HEA) in the home and similar places in the use of a variety of electrical appliances. Also known as residential appliances, daily appliances. The United States is the birthplace of home appliances. 1879 U.S. T.A. Edison invented the incandescent lamp. The beginning of the 20th century, the United States E. Richardson invented the electric iron on the market, prompting other household appliances came out one after another. Vacuum cleaners, electric washing machines, compressor refrigerators, electric stoves, air conditioners, automatic washing machines came into being. 1880s, the Edison effect of the discovery and verification of the existence of electromagnetic waves experiments for the birth of electronics to create the conditions. the early twentieth century, the United Kingdom, the United States and other countries invented the first generation of electronic devices, electron tubes. 1919 super-aberration receiver was introduced for the radio to create the conditions for development. The conditions were created for the development of radio.

1923 ~ 1924, the United States V.K. Zvoregin invented the camera tube and picture tube, 1931, assembled into the world's first all-electronic television system. 1954, the United States began to use color television broadcasting. Magnetic (wire) tape recorders and tape recorders were introduced in 1898 and 1935, based on the invention of cassette tapes in the Netherlands in 1963, cassette tape recorders were rapidly popularized. The invention of integrated circuits, so that electronic technology into the era of microelectronics technology, so that household appliances to a new level.

The classification of household appliances has not been unified in the world. But according to the function of the product, the use of classification is more common, roughly divided into eight categories.

①Refrigeration appliances. Including household refrigerators, cold drink machines.

② air conditioners. Including room air conditioners, electric fans, ventilation fans, hot and cold air conditioners, air dehumidifiers and so on.

③Cleaning appliances. Including washing machines, dryers, irons, vacuum cleaners, floor waxers and so on.

④Kitchen appliances. Including electric cooker, microwave oven, induction cooker, electric oven, electric rice cooker, dishwasher, electric water heater, food processor, etc.

⑤ Electric heating appliances. Including electric blankets, electric quilts, water-heated blankets, electric clothing, space heaters.

6 cosmetic health care appliances. Including electric shaver, hair dryer, hair straightener, ultrasonic face washer, electric massager.

7 sound and image appliances. Including mini projectors, televisions, radios, tape recorders, video recorders, video cameras, combined stereos and so on.

8 other electrical appliances, such as smoke and fire alarms, electric bells and so on.

With the improvement of life, the water purifier has also become a member of the household appliances, more and more families to use this new type of electrical products: with most of the world's water pollution is serious, exacerbating the contradiction of water scarcity. Traditional tap water treatment methods, can not guarantee the provision of good quality drinking water, and in the municipal water supply there is also the problem of secondary pollution, such as high-rise water tanks water supply, the long pipeline water delivery, will cause potential rust, sediment and microorganisms and other pollution problems. Therefore, all kinds of water purifiers came into being.

Home appliances, or appliances for short, are appliances that are powered (or mechanized) by electricity to help perform household chores, such as cooking, food preservation, or cleaning, and can be used in corporate or industrial environments in addition to the home. Basically, household appliances are categorized into large appliances (white goods, black goods) and small appliances.

-Functions of household appliances

1, safety of household appliances are widely used, and the user does not necessarily have knowledge of electricity, so its safety performance is very important, the requirements of electrical appliances in the event of a mechanical or electrical failure will not cause personal injury accidents. Most countries have promulgated regulations and standards for the safe management of household appliances, and some countries also use legal forms of enforcement. The International Electrotechnical Commission (IEC) has promulgated safety rules for household appliances. China's national standards for household appliances are equivalent or equivalent to the IEC safety rules.

2, practical utility is the basic characteristics of household appliances. The product should have a basic function, reasonable structure, easy to operate, so that the user does not need to have specialized skills can also be used correctly.

3, reliable reliability is a comprehensive indicator of the quality of household appliances. China UnionPay suggests that the average trouble-free working time is a major indicator of the reliability of household electrical appliances. The production process of the product needs to implement strict total quality management to ensure the consistency and stability of product quality.

4, novel household appliances have the characteristics of beautifying the family, and therefore should be decorative. Product modeling and appearance should not only have a distinctive period, reflecting a certain period of scientific and technological level and people's aesthetic interests, and to reflect the scientific structure, the rationality of the selection of materials and advanced technology.

5, less energy-consuming to improve the efficiency indicators of household appliances, reduce energy consumption is the main production of household appliances in the direction of long-term efforts. The United States in December 1975 to formulate energy policy and protection of 14 kinds of energy-consuming household appliances provide a minimum energy efficiency standards. Japan in June 1979 enacted the rational use of energy law, more energy-consuming refrigerators, air conditioners, energy efficiency to determine the judgment standards, and provides for specific products on the set of energy efficiency marking, in order to facilitate consumer choice.

6, the penetration rate of household appliances reflects the cultural and economic level of a country. Usually, countries with high GNP, high per capita income and high per capita electricity consumption also have high penetration rates of household appliances
