Embodiment 1
[0031] Embodiment 1, Fig. 1 is a schematic view of the internal structure of an embodiment of the static-free electric water heater according to the present invention. It can be seen from Fig. 1 that the non-static electric water heater includes a casing 1, a water tank 2, an insulation layer 3, an outlet pipe 4, water inlet pipes 5 and 51, overflow pipes 6 and 61, an electric heating element 7, a temperature controller 8, The water level probe 9 and the water flow sensor 10; wherein the outer end of the water inlet pipe 51 is connected with the tap water pipe, the outer end of the water outlet pipe 4 is connected with the water mixing valve, and the water inlet electric control valve, the overflow water electric control valve and the drainage electric control valve are connected as one body Device—electric control valve 56; the electric control valve 56 shares a valve body, a spool and an electric control drive mechanism with a tri-stable state. The closed and overflow electr...
Embodiment 2
[0032] Embodiment 2, FIG. 5 is a schematic diagram of the internal structure of Embodiment 2 of the non-static electric water heater according to the present invention. It can be seen from Fig. 5 that the non-static electric water heater includes a shell 1, an inner tank 2, an insulation layer 3, an outlet pipe 4009, water inlet pipes 5 and 51, an overflow pipe 61, an electric heating element 7, a thermostat 8, a water level Probe 9, water flow sensor 1009; It is that outlet pipe 4 (Fig. 1) and overflow pipe 6 (Fig. 1) in embodiment one are combined into one to form outlet pipe 4009 and branch 41 shown in Fig. 5; its The internal structure of the electronically controlled valve 11 is the same as that of the electronically controlled valve 56 in the first embodiment.
Embodiment 3
[0033] Embodiment 3, FIG. 6 is a schematic diagram of the internal structure of Embodiment 3 of the non-static electric water heater of the present invention. It can be seen from Fig. 6 that the static-free electric water heater includes a casing 1, a water tank 2, an insulating layer 3, an outlet pipe 4, water inlet pipes 5 and 51, overflow pipes 121 and 122, an electric heating element 7, a thermostat 8, The water level probe 9 and the water flow sensor 10; wherein the outer end of the water inlet pipe 51 is connected with the tap water pipe, the outer end of the water outlet pipe 4 is connected with the water mixing valve, and the water inlet electric control valve, the overflow water electric control valve and the drainage electric control valve are connected as one body Device—electric control valve 12; the electric control valve 12 shares a valve body, a spool and an electric control drive mechanism with a tri-stable state. between) and the drainage electric control valv...
