The water in the hot water bag falls down
Electric hot water by electromagnetic heat generated, in order to prevent the leakage of electromagnetic stuff is closed, will produce electricity magnetic iron and magnetic interaction is, the so-called "water" which produces eddy current and hysteresis and then produce heat energy, and transformer why fever is relevant because of hysteresis and eddy current heat, the transformer manufacturer made a piece of silicon steel sheet is to reduce the hysteresis and eddy current, by heat, and heating water bag on the contrary. But be careful when using it.
There is a plug on the hot water bag, pull it up, and then add a little bit of water with a small bottle, add pure water, but can not be poured out of the water or change the water, because the bag with powder,
Can add water, but can not drain the water inside.
