Embodiment 1
[0045] Embodiment one, see figure 1 , the storage type water heater includes a water tank 91, a heating element (not shown in the figure), a hot water pipe 911, a water mixing valve 92, an overflow pipe 831, a tap water pipe 811 and a water supply pipe 821, and the water mixing valve 92 The hot water inlet is connected to the hot water pipe 911 and the cold water inlet connection pipe 901. The hot water valve arranged between the hot water pipe 911 and the water outlet pipe 921 in the mixing valve 92 is used as a control valve, and the connecting pipe 901 is connected to the tap water pipe 811. The water control expansion device 90 and the water inlet valve 81 are connected to the normally closed water supply valve 82 between the connecting pipe 901 and the water supply pipe 821; the normally open overflow valve 83 is connected between the water supply pipe 821 and the overflow pipe 831; the water control expansion device 90 and the overflow The dotted line between the valve 8...
Embodiment 2
[0049] Embodiment 2. Figure 6 is a schematic diagram of the connection structure and control principle of this embodiment. The difference between Embodiment 2 and Embodiment 1 is that the water mixing valve in Embodiment 1 is changed to a faucet-type water outlet valve 920. Between the water outlet valve 920 and the hot water pipe 99, the one-way valve 910 is used as the control valve, and the joint 9011 between the connecting pipe and the water outlet valve is replaced with a smaller pipe diameter. figure 1 The same, and the water-controlled expansion device with the structure shown in Figure 2 is adopted, and the structures of the stator and the moving plate in the switching valve are also respectively in the structures of Figure 4 and Figure 5. The reason why the connection 9011 adopts a smaller diameter is that After preventing the water outlet valve 920 from opening, all the water in the connecting pipe will flow away through the water outlet valve and cannot push out the ...
Embodiment 3
[0050] Embodiment three, see Figure 7 , the difference between the third embodiment and the second embodiment is only that the one-way valve in Figure 6 is changed to Figure 7 The normally closed cut-off valve 9100 is used as the control valve, and the stop valve 9100 is controlled by the expansion wall in the water-controlled expansion device. Similarly, the stop valve 9100 can also be integrated in the switching valve together with the overflow valve and the water supply valve. Its working principle is similar to that of the above-mentioned embodiment, and will not be described here.
