上述創作雖能達到其創作目的，然，其在操作使用的過程中，會產生如下的缺失： Although the above creation can achieve its creative purpose, however, in the process of operation and use, the following defects will occur:

由於習用電熱水器在首次加熱至預定溫度後的靜置時，往往因該儲水筒1與儲水筒1外側的空氣接觸面積過大的情況下，會使熱水經由儲水筒1而直接傳導散熱至空氣中，而使得該儲水區10內的熱水會快速地降溫至預定啟動溫度，如此一來，其不 但要整個儲水區的溫水水源全部再加熱外，同時，亦會使其加熱次數過於頻繁，而增加其耗電量，進而增加消費者的電費成本為其一大困擾。 When the conventional electric water heater is heated to a predetermined temperature for the first time and then stands still, the hot water will be directly conducted to dissipate heat through the water storage tank 1 due to the excessive contact area between the water storage tank 1 and the air outside the water storage tank 1 . In the air, the hot water in the water storage area 10 will quickly cool down to the predetermined starting temperature, so that it does not However, in addition to reheating all the warm water sources in the entire water storage area, it will also cause the heating frequency to be too frequent, which will increase its power consumption and thus increase the electricity cost of consumers.

因此，如何開發出一種能有效地縮短再加熱的次數，且能降低無形熱能之損耗者，此乃為業者當前極需優先解決的技術課題。 Therefore, how to develop a device that can effectively shorten the number of reheating and reduce the loss of invisible heat energy is a technical issue that the industry needs to solve as a priority.
