Below in conjunction with accompanying drawing the utility model is described in further detail.

Overall structure cross-sectional schematic when Fig. 1 removes shell for the utility model.

Fig. 2 is its outline drawing.

As shown in Figure 1, 2, the bottom panel 2 that the utility model is hung by water bag 3, water circulating pump 4, expansion tank 7, electric controller 8, control panel 12, shell 13 with on the wall is formed, and water bag 3 is a drum shape, on its outer wall heat-insulation layer is arranged.Heat exchange coil 5, electrothermal tube 9, recirculated water pump line 14 are arranged in the water bag 3, and two external parts of heat exchange coil 5 stretch out from water bag 3 lower ends, and one is bathing delivery port 10 for 11, one of bathing water inlets.Heating delivery port 1, heating water return outlet 6 are located at the upper end of water bag 3, and heating water return outlet 6 joins by water circulating pump 4 and recirculated water pump line 14, heating water return outlet 6 and and expansion tank 7 join.Electrothermal tube 9 is located in the heat exchange coil 5 coiling circles, and its electrical input is located at water bag 3 lower ends.Expansion tank 7 is located at right side the first half of water bag 3, and electric controller 8 is located at right side the latter half of water bag 3, and electric controller 8 is below expansion tank 7.Water circulating pump 4 is located on water bag 3 and between the two the recirculated water pump line 14 above the expansion tank 7.Control panel 12, shell 13 are half bag shape, and control panel 12 is in the water heater outer lower portion, and shell 13 is in its outer upper, and bottom panel 12 is a rectangular slab, are located at the side of water heater by wall.

The utility model recirculated water pump line is that heating return pipe 14 extends to water bag 3 bottoms; electric controller 8 is selected silicon controlled module for use; temperature controller is contained in control panel 12 inboards; temperature controller has temperature measurement, overtemperature protection, fault demonstration and automatic shutdown function, and water bag 3 skins are the integrated poured super thick polyurethane insulation coating that forms.
