Quality of the merits of household appliances identification method
How to identify color TV 1 chroma knob to minimum, adjust brightness, contrast, image clear and soft, structured. 2 chroma knob turn up, from black and white to color images over the period, the color should not appear chaotic flow phenomena. After 3 calls up the most emotion image clarity, frequency tuning knob continues to rotate, the image becomes grainy distortion, frequency close the switch from trimming, image clarity situation should be restored immediately. 4. Observe whether natural color coordination. 5 of the environmental interference, but appears on the screen wavy, textured, stripes are not normal. 6 adjust the volume appropriately large, sweet voice distortion. 7. Adjustment measure, the contrast knob should have a significant role. 8 pre-tilt turn, the screen flashes only slightly. 9 off the power switch, the screen does not stay light band or spot. How to identify the pros and cons of refrigerators When you look at the shape identification, pay attention to the shape of color, whether peeling paint and smooth uneven. Connect the power to regulate the temperature, should be transferred to the second file. Let automatic controller for automatic stop, since the opening times, check the temperature control device is reliable and effective, and whether the normal operation of the compressor and check the noise level, then adjust the knob and then spin to the "stop" position, a half-hour can occur within the evaporator frost water, in this examination of the evaporator walls is uniform, the heat is the same, whether the final inspection doors shut tight and flexible. How to identify the pros and cons cooker First in the pot (or liner) into the casing, turning left and right a few times to check the bottom of the pot with a heating plate casing is consistent, efficient use of consistent high. After connecting the power supply, use your fingers to touch the shell, there should be tingling feeling (leakage). Cook for five minutes after you press the switch, the temperature at the bottom of the pot is about 103 degrees, then, should be able to contact temperature limiter automatically disconnected, cooking switch bounce, turn 60 degrees Celsius in the insulating state. Rapid identification of the refrigerator thermostat 1. The first thermostat switch to "strong cold" file (must be five minutes later), then the compressor to work. 2 to be 5 - 7 minutes, the switch to the "weak cold" file, the compressor should stop working, while the switch will be "in despair" soon. 3 wait another five minutes, will switch to the original "strong cold" position, the compressor should work, this time it. This thermostat can be considered normal. How to identify automatic washing machine 1. Figure out the control program of the washing machine is a mechanical cam controller or computer type. 2 test machine, observe the entry, consistent washing, drainage, drying and instructions should be stipulated time. 3 pointer to "drying" procedure, put on the cover is opened, washing drying tube should be stopped within 10 seconds. How to identify the advantages and disadvantages of fans 1 watch style. 2, see Appearance: In addition to the elegant appearance, but also the paint and chrome is smooth, straight, no wrinkles, smooth blade rotation should measure performance 3: Open the button to see if Lee winded, shaking his head and timer test whether the Spirit accurate control, there is no difference in the wind, smooth leaves, no noise, no leakage, temperature normal. Identification of the merits of quartz digital watches After watching a good appearance, the crown is pulled out to _set_ aside the needle position, second hand should immediately stop beating, just tip the scale toward points, both positive and negative direction dial needle, second hand should stop. Push back the crown for a second, the second hand should immediately resume the beating, travel time, beating each one should be just the second hand is a grid, the second hand and the glass surface without grazing phenomenon.

Ash can easily move your TV screen, depending on the available cleaning agents cleaning spirit and a clean, soft cloth to scrub group, it can remove fingerprints, dirt and grime on the screen, or use a cotton ball dipped in cleaning fluid to clean the heads, and finally Be sure to dry. Tip: Do not use gasoline, solvents or any chemical agents to clean the TV cabinet. Irons Eventually becoming cleaning hazards: the bottom of the iron due to high temperature and moisture, will produce the same kind of like rust marks, even if the bottom is made of iron chrome or stainless steel is no exception. Cleaning methods: remove traces of iron at the bottom, about 80% preferred cleanser, wax, about 10%, about 10% vegetable oil dubbed polishing abrasive. When used, this abrasive coating on the soleplate of the iron, with traces of chemical fiber cloth wipe hard place, you can promptly remove traces. Or traces of toothpaste on the floor, wipe again with silk, the same effect. Tip: Irons cleaning it requires patience, it is recommended to make adequate preparations for cleaning before. Water Heater Eventually becoming cleaning hazards: electric water heater in use for some time, it will form a large scale interior, when the scale thickening to a certain extent, not only to extend the heating time, and will happen to crack, there is some damage to the interior, so that prolonged heating, hot water production decreased. Cleaning methods: electric water heater drain valve does not need professionals to clean. Gas water heaters and solar water heaters long-term use should be regularly checked by qualified personnel and cleaning and maintenance. Tip: Some electric water heater with a drain valve, self-discharge according to the instructions.

Reference to identify security appliance life "overage" appliances
TV: CRT TV, the image is not clear when the situation occurs, the screen shaking, etc., it means that the relevant components are aging, and radiation will increase in the event of a collision, quenching, sudden fever, etc., can cause an explosion CRT . (Flat-panel TVs appear shorter, the problem does not involve overage) Refrigerator: refrigerant leak occurs, the operation sound too large, or even more severe shaking during operation, while significant increase in power consumption than before, are "overage" of features. It is reported that the use of a refrigerator 10 years later, the power consumption will become two times the initial use. Washing machine: often seepage, leakage and other problems, consumers may consider replacement. Air conditioning: a boot on the direct injection of dust, mixed with a burst of wind blowing musty, some even out dark dirty water, which remind the owner: The air conditioner may have to use the limit. The useful life of the security appliance reference Colour 8-10 years Electric water heater 8 years The air conditioner 8 to 10 years Irons 9 years Clock 8 years Electric blankets 8 years Cooker 10 years Refrigerator 12 to 16 years PC 6 years Fans 10 years Gas stove 8 years Washer 8 years Hair Dryer 4 years Microwave for 10 years Electric shaver 4 years Cleaner 8 years

jiayong dianqi Household appliances household electric appliance Mainly refers to a variety of electrical and electronic appliances used in the home and similar places. Also known as consumer electronics, household appliances. Appliances so that people from the heavy, trivial, time-consuming housework liberation, for mankind to create a more comfortable and beautiful, more conducive to the health of the living and working environment, providing a rich cultural and recreational conditions, has become a modern necessities of family life. A Brief History of appliances come nearly a hundred years of history, the United States is considered to be the birthplace of household appliances. In 1879, the United States TA Edison invented the incandescent lamp, creating a household electricity era. American power industry development, for the development of household appliances has created favorable conditions. Early 20th century, the United States E. Richardson invention irons on the market, was generally welcomed. Widespread use of iron was only changed the traditional power at night and cause other appliances after another. Therefore, people think the U.S. home appliance industry began in earnest in irons. In 1907, a vacuum cleaner with the advent of modern product prototype. In 1910, electric washing machines and compressors, household refrigerators have come out. 1914 Dianzao appear. In 1930, the advent of room air conditioners. In 1937, the successful development of fully automatic washing machines. Since then, the production of electrical products has grown rapidly increasing variety and updated. The 19th century, the Edison effect of electromagnetic waves exist discovery and validation experiments for the birth of electronics to create the conditions. In 1895, Italy G. Marconi invented wireless telegraphy Markov, contributed to the emergence of wireless phones and radio broadcasting. In 1904, the British JA Fleming invented the vacuum tube diode. In 1906, the United States LD Forrest invention triode vacuum tube with amplification capabilities. After tetrode, pentode, more pole tubes and composite pipe after another. Tube as the first generation of electronic devices, before the invention of the transistor nearly half a century, played a very important role. In 1919, the advent of superheterodyne receiver, creating conditions for the development of radio. In the same year, the first broadcast of a regular language and music radio stations built in the UK, the following year, the United States has built a Pittsburgh radio station. In 1923 and 1924, the United States have invented VK Ziwo Lei Jin camera tubes and tubes; 1931, he assembled the world's first all-electronic television system. About in the late 1930s, British, American has begun a pilot television broadcasts, after World War II, television broadcasting will gradually spread in all countries. In 1954, the United States started using the NTSC color television broadcasts. In 1963 and 1966, the Federal Republic of Germany, France, were identified PAL and SECAM compatible color television system. 1898 Danes invented magnetic (steel) tape recorder, in 1935 the German General Electric Company made a tape recorder, in 1963 the Dutch company Philips invented the cas_set_te, from cas_set_te tape recorder quickly spread. 1950s rise of the electronics industry and the plastics industry, and promote the rapid development of household appliances. Application of the invention of the transistor, especially the invention of the integrated circuit, electronic technology into the microelectronics era, there has been a huge leap to make household appliances to a new level. 1970s, the advent of the microcomputer, to promote the development of automation and intelligent appliances direction, a group of high-tech type of home appliances have appeared. Categories range of household appliances, varies by country in the world has not yet formed a unified classification of household appliances. Currently, there are two main methods by product function and use of electrical works and by product category. The latter will be divided into refrigeration appliances, electric, electric, electronic four categories, this classification is not perfect. Classification by product features and uses of the more common, but there are different specific sub-law countries, divided into eight categories. ① refrigeration appliances: also known as freezing appliances. Frozen for goods (mainly food), chilled, including household refrigerators, cold drinks machines. ② air conditioning appliances: air conditioning electrical short. For regulating the indoor air flow, temperature, humidity, and clear the air of dust, including room air conditioners, fans, ventilation fans, hot and cold air, air dehumidifiers, etc.. ③ Clean appliances: for fabric cleaning, maintenance and equipment maintenance and indoor environments, including washing machines, dryers, irons, vacuum cleaners, floor waxing machine. ④ kitchen appliances: for food preparation, cooking and kitchen hygiene, including electric range, microwave, induction cooker, electric oven, electric cooker, dishwasher, electric water heaters,
