Embodiment 1
[0036] Embodiment one, figure 1 It is a schematic diagram of the internal structure of Embodiment 1 of the non-static electric water heater described by the inventor. from figure 1 As can be seen in the figure, the static-free electric water heater includes a water tank 1, an electric heating body 13, a thermostat (not shown in the figure), a controller (not shown in the figure), a water inlet pipe 31 and a water outlet pipe 32, and the water inlet The electric control valve, the water outlet electric control valve, the overflow water electric control valve, the water flow detection valve and the water discharge electric control valve are integrated in the connected device—the electric control valve 6, and its internal structure in normal state is as follows: figure 2 As shown, the holes 211, 221, 311, 321, 411 on the valve body 61 are respectively connected to the cold water pipe 21, the hot water pipe 22, the water inlet pipe 31, the water outlet pipe 32, and the overflow ...
Embodiment 2
[0039] Embodiment two, Figure 14 It is a schematic diagram of the connection between the electric control valve and each pipe after the drainage function is added on the basis of the first embodiment. It not only increases the drainage pipe 96, but also the internal structure of the electric control valve is different. from Figure 15 Visible in, the valve body is in figure 2 Open a hole 961 on the shown valve body, combine Figure 14 , the overflow pipe 41 is changed to the hole 961, and the original hole 411 is connected to the drain pipe 96, and its spool 862 is also slightly different from the original one. Figure 15 It is a schematic diagram of the internal structure of the electric control valve 86 when it is in a normal state, and the conduction state of each pipe is the same as that of Embodiment 1; Figure 16 is the state of use, and the conduction state of each tube is also the same as that of Embodiment 1; Figure 17 It is the drainage state, the water in the...
