accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
the specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, storage-type electric water heater of the present invention, comprise shell 1, heater 2, inner bag 3, temperature sensor 4, heat-insulation layer 5, circuit board 6, the first outlet pipe 8, water inlet pipe 9, the second outlet pipe 10 and mixed water valve 15, wherein inner bag 3 devices are in shell 1, circuit board 6 devices are on a side inwall of shell 1, heat-insulation layer 5 is filled between inner bag 3 and shell 1, heater 2 and temperature sensor 4 are placed in inner bag and are packed in by circuit board 6 one side inner bag evagination circular arc wall, water inlet pipe 9, the first outlet pipe 8 and the second outlet pipe 10 be the bottom at inner bag 3 through shell 1 device respectively, the delivery port 91 of water inlet pipe 9 is near the bottom of inner bag 3, 81 tops that extend to inner bag 1 of water inlet of the first outlet pipe 8, the delivery port of the first outlet pipe 8 is communicated with the hot water inlet of mixed water valve 15, between the delivery port of the first outlet pipe 8 and mixed water valve 15 hot water inlets, on pipeline, device has water flow sensing unit 16, the water inlet of water inlet pipe 9 is communicated with the cooling water inlet of mixed water valve 15, between the cooling water inlet of the water inlet of water inlet pipe 9 and mixed water valve 15, device has normally open solenoid valve 13, the water inlet of the second outlet pipe 10 is in the middle part of inner bag, delivery port passes shell 1 and is communicated with the bypass pipe of the second threeway 14 by normally closed solenoid valve 11, the second threeway 14 devices are on the pipeline between normally open solenoid valve 13 and the cooling water inlet of mixed water valve 15, normally closed solenoid valve 11, normally open solenoid valve 13, water flow sensing unit 16 and automatic water-mixing valve 15 are connected to circuit board 6 by wire.
In the present embodiment, the first threeway 12 is housed on described water inlet pipe 9, normally open solenoid valve 13 is communicated with the first threeway 12 bypass pipes.Described mixed water valve 15 is the mixed water valve of automatic or manual.
