<p><P>PROBLEM TO BE SOLVED: To provide a hot water storage type electric water heater installable in a limited installation space and superior in extrusion performance of hot water in a hot water storage tank and a boiling-up performance. <P>SOLUTION: This hot water storage type electric water heater comprises the hot water storage tank 10, a water inlet portion 11 formed on a prescribed position of the hot water storage tank, a hot water outlet portion 12 formed on a position different from the water inlet portion, and a first partitioning structure 20 forming a plurality of flow channels over the neighborhood of the water inlet portion to the neighborhood of the hot water outlet portion. The hot water storage tank is installed with its lateral length longer than its vertical height with this water heater installed, a second partitioning structure 30 comprising a plurality of flow channels 31-35 composed of a plurality of opening portions, is disposed at a water inlet portion side of the first partitioning structure, and an average opening area of the lower-side flow channels of the second partitioning structure 30 is smaller than an average opening area of the upper-side flow channels, so that the water flowing out from each of the flow channels of the second partitioning structure 30 flows into each of the flow channels of the first partitioning structure approximately at an uniform velocity. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
