电热杯是底部内藏电热丝的电热饮水器具.使用220伏交流电源.功率一般为300瓦,接通电源几分钟就能加热杯中的水,常温情况下10分钟左右便可煮沸一杯水.它的问世无疑给人们的生活带来方便.但使用不慎也会给人们造成不幸.如天津市某厂女工用电热杯烧开水,因突然停电忘了拔下电源插头就离开房间.后来电把电热杯内的水很快被烧干,胶本制做的杯座也被烧毁,引起火灾;又如洛阳市某工艺品贸易大厦一营业员用电热杯烧开水,下班时忘了拔下电源插头,结果酿成一起重大火灾.有关部门对电热杯进行的模拟试验表明:一只盛满水的电热杯,从接通电源到引起可燃物起火、总计用了2小时22分钟;从电热杯内的水被烧干至引起可燃物着火;仅需29分钟.由此可见,电热杯如果使用不当是很可能引起火灾事故的.为了安全使用电热杯,必须做到以下几点:1.插上电源后,就要守着它,不能再去干别的事,如果使用中突然停电,一定要及时拔下电源插头.2.不能让电热杯中的水煮沸
The electric cup is an electric hot water appliance with a built-in heating wire at the bottom and uses a 220 VAC power supply with a power of 300 watts. The water in the cup can be heated for a few minutes after the power is turned on, and a glass of water can be boiled in about 10 minutes under normal temperature conditions. Its advent is undoubtedly bring convenience to people’s lives.But the use of carelessness can also cause unfortunate people.As a factory in Tianjin, a worker with a hot cup of boiling water, because of a sudden power outage forgot to unplug the power plug to leave the room. Electric cup of water quickly burned dry, plastic cup made of the cup holder has also been burned, causing a fire; Another example of a crafts trade in Luoyang City, a salesperson with electric hot water to boil, forget to unplug the power plug off work, The result led to a major fire.The department conducted a simulation test on the electric cup showed that: a water-filled electric cup, from the power to cause combustible fire, spent a total of 2 hours and 22 minutes; from the electric cup Water is burned to cause ignition of combustibles; only 29 minutes. Thus, the electric cup if used improperly is likely to cause a fire accident. In order to safely use the electric cup, you must do the following: 1. Plug in the power After, we must guard It can not do anything else, if the sudden blackout in use, be sure to unplug the power plug in time .2 can not make the water in the electric kettle to boil
