All over the country have been chasing a guy named "Hot" "hot". In addition to people who are hot, there are home appliances. Recently, the reporter learned from some home appliance repair points such as air conditioners and TVs that due to the unstable weather such as high temperature and thunderstorm in summer, the “summer disease†of household electrical appliances frequently occurred. Relevant data show that from July to September, the damage rate of TV sets is about three or four times that of other months. In order to avoid the "onset" of common household appliances in the summer, our reporter interviewed technicians of home appliance manufacturers such as Gree, Midea, TCL, etc., and compiled a special specification for the use of Changsha summer appliances. Our reporter Wang Chengchang intern student Zhong Jingxian Changsha reported
Air conditioning to prevent "heatstroke" Remember to "bath"
Symptoms: In the case of high temperature in summer, the air conditioner almost enters a full-load working state, which makes some air conditioners have a small amount of airflow and a poor cooling effect. Why does air conditioning also "heat stroke"? How to prevent air conditioning "heatstroke"?
Prevention: Hunan Gree Electric Appliances (000651, shares it) technical staff told reporters, we must remember to give the summer air conditioning "bath".
According to reports, in all household appliances, air pollution dust pollution is the most serious, if the filter net, evaporation sheet ash, the indoor air quality will decline, easy to cause air conditioning disease. “In general, it is best to wash once every half month in the summer, so that the air conditioning air supply is fresher and healthier, and the heat exchange efficiency can be effectively increased by 10%-30%, and the safety factor will be higher.â€
The technician reminded that if you clean the air conditioner yourself, it is best to use physical cleaning. Prepare clean towels, toothpaste toothbrushes and special neutral detergents, rinse with water below 40 °C, and then dry them in the shade to clean the indoor unit. Avoid cleaning the air conditioner with acidic chemicals, otherwise it will cause corrosion and rust of the air conditioner and shorten the service life.
The refrigerator prevents "heatstroke" and reduces the number of door opening
Symptoms: In the summer, the long-term use of the refrigerator, coupled with the high temperature, the refrigerator has not only become a "little tiger" in summer, and always feels that the cooling effect is greatly reduced, and even the compressor is damaged.
Prevention: US professionals recommend: First, the refrigerator should be defrosted in time. When the frost layer in the freezer reaches 4-6 mm, it must be defrosted; second, reduce the number of times the refrigerator is opened; third, the food storage in summer is relatively large, and the food should not be placed in the refrigerator. There should be a gap between them so that the air-conditioning convection and temperature are uniform. The small package can reduce the time of cold-through, save power and facilitate access.
In addition, the US technicians reminded that in the summer, we must focus on protecting the "engine" of the refrigerator. Because the summer ambient temperature is high, the temperature difference between the inside and outside of the refrigerator is large. If a large amount of hot air enters the refrigerator, it will cause the compressor to start frequently and operate for a long time to overheat and even burn the compressor. Therefore, "we can reduce the number of door opening; create a good cooling environment for the refrigerator, such as the bottom of the wooden strip; the temperature of the hot food drops to room temperature and then into the box."
At the same time, color TVs are most sensitive to summer “explosive thunder†and “lightningâ€. TCL TV after-sales expert Zeng Bo suggested that in the event of thunderstorms, try not to watch TV and use the TV network function, and unplug the power plug and signal cable to avoid the TV being damaged by lightning.
Secondly, pay attention to ventilation and heat dissipation. Do not put cotton pads or foam pads underneath the machine after installation. These “protection†measures often cause poor ventilation inside the TV set, which is difficult to dissipate heat and cause overheating damage. Therefore, it is necessary to keep the venting holes around the casing unobstructed, and leave a space of 5-10 cm or more around it. Do not cover the TV dust cover immediately after shutting down. “It’s best to have a TV every day in the summer.â€
Accessories for cameras are mainly for care, protection, special effects and functions.
Lens hood: used on the end of a lens to block the sun or other light source to prevent glare and lens flare (see also matte box).
Lens cap: covers and protects the lens during storage.
Lens adapter: sometimes called a step-ring, adapts the lens to other size filters.
Lens filters: allow artificial colors or change light density.
Lens extension tubes allow close focus in macro photography.
Flash equipment: including light diffuser, mount and stand, reflector, soft box, trigger and cord.
Care and protection: including camera case and cover, maintenance tools, and screen protector.
Large format cameras use special equipment which includes magnifier loupe, view finder, angle finder, focusing rail /truck.
Battery and sometimes a charger.
Some professional SLR could be provided with interchangeable finders for eye-level or waist-level focusing, focusing screens, eye-cup, data backs, motor-drives for film transportation or external battery packs.
Tripod, microscope adapter, cable release, electric wire release.
Dew shield - Prevents moisture build up on the lens.
