The specific embodiment:
Embodiment one, Fig. 1 are the structural representations of storage water heater embodiment one of the present invention.Belong to first technical scheme, as can be seen from Fig. 1, described storage water heater, comprise water tank 27, heating device (not drawing among the figure), expander 23, mix water valve 26, overflow pipe 28, cold water pipe 241, hot-water line 262 and water inlet pipe 22, the hot water inlet that mixes water valve 26 connects hot-water line 262, and the cooling water inlet that mixes water valve is connected to connecting leg 251; The outer side of expanding wall of expander 21 is connected with controll block 23, makes controll block 23 with the expansion wall motion, and controll block 23 both sides are provided with tooth bar, and the expander inner chamber communicates with connecting leg 251; Be provided with inlet valve between connecting leg 251 and the water inlet pipe 22, the switch block 25 of control inlet valve switch be one with controll block 23 on the gear that matches of tooth bar; By-pass valve control and spilling water valve are arranged in the switching valve, and this switching valve uses a switch block 24, switch block 24 for controll block 23 another sides on the gear that matches of tooth bar.Open when mixing water valve 26, the water of expander 21 inner chambers is through mixing water valve and outlet pipe 261 outflows, expander is because of interior drops, controll block 23 moves down, thereby driving switch block 24 and 25 rotates, the sequence of movement of each valve is: (have only one road running water through water inlet pipe 22 this moment to open inlet valve gradually, inlet valve, connecting leg 251, mix water valve 26, outlet pipe 261 flows out, be the cold water road)-one close the spilling water valve---opening by-pass valve control---open fully inlet valve (this moment another road running water appears through water inlet pipe 22, inlet valve, connecting leg 251, by-pass valve control, cold water pipe 241 enters water tank 27, hot water in the water tank flows into the hot water inlet that mixes water valve 26 through hot-water line 262, mixes with above-mentioned cold water road after the outlet outflow that mixes on the water valve outlet pipe 261 is used for the user); Close when mixing water valve, also be closed between hot-water line 262 and the connecting leg 251, the water that enters the expander inner chamber through inlet valve makes to press in the expander and increases rapidly and expand, move on the controll block 23, thereby drive switch block 24 and 25 counter-rotatings, the sequence of movement of each valve is: the opening of inlet valve diminishes rapidly, and---closing control valve---is opened the spilling water valve---and is closed inlet valve fully, on stopping, controll block 23 moves, at this moment, water tank communicates with atmosphere through cold water pipe 241, spilling water valve, overflow pipe 28.A plurality of mixed water valves in parallel can realize that central authorities supply water on connecting leg 251 and hot-water line 262.
In the present embodiment by-pass valve control and spilling water valve are synthesized the switching valve of a shared switch block 24, inlet valve uses a switch block 25 separately, rather than by-pass valve control, spilling water valve, inlet valve three be synthesized together, be for make switching valve be easy to produce.Wherein the structure of still in switching valve and the water intaking valve and moving plate can be referring to the Fig. 7 that discusses later, Fig. 8, Fig. 9, Figure 10.
When the mixed water valve 26 of present embodiment cuts out, be that the hot and cold water inlet between connecting leg 251 and the hot-water line 262 is cut off; If add a check valve that flow to mix the water valve direction between hot-water line 262 and mixed water valve, the structure that then should mix water valve also can be need not cut off the hot and cold water inlet who mixes water valve in off position the time.Certainly, because the opening action of check valve, be actually by opening in the switching valve to increase behind the by-pass valve control and press in the water tank and it is backed down, so, the opening of check valve can think and the opening synchronously of by-pass valve control, therefore can increase by one and replace check valve with the synchronous valve of by-pass valve control on switching valve, and this is that those skilled in the art are all attainable on basis of the present invention, and be a kind of simple replacement on basis of the present invention, within the scope of the invention involved.
Embodiment two, Fig. 2 are the structural representations of storage water heater embodiment two of the present invention.Compare with embodiment one, expander 31 among the embodiment two is a ball, this ball is placed in the spacing bucket, the top 331 that controll block 33 lower ends are provided with sphere is used to withstand ball, in the expander during drops, controll block can be leaned on self gravitation or at the controll block upside the downward spring of elastic force is set and realize moving down, and its operating principle is identical with embodiment one; Between hot water inlet that mixes water valve 36 and hot-water line 362, check valve 361 is set in addition, so, when the mixed water valve 36 of embodiment two cuts out, the pipe 363 with expander 31 between can communicate, its benefit is to mix water valve 36 to can be designed as the mixed water valve of the electric operated thermostatic that is built in the water heater, the data that relevant electric operated thermostatic mixes water valve is not done to state at this on November 29th, 2000 disclosed Chinese patent bulletin CN2408396Y more.
Also can be with 36 cancellations of the mixed water valve among Fig. 2 embodiment, directly will manage 363, connecting leg 368, outlet pipe 369 be communicated with, outlet pipe 369 is realized that as the hot water supply pipe of a plurality of mixed water valves easy central authorities supply water, and this moment, the cold water pipe of each mixed water valve directly connect running water pipe.Certainly, also can realize central water supply at a plurality of mixed water valves 36 in parallel on pipe 363 and the connecting leg 368.
Embodiment three, Fig. 3 are the structural representations of storage water heater embodiment three of the present invention.Belong to second technical scheme, the storage water heater comprises water tank 47, heating device (not drawing among the figure), expander 43, outlet valve 46, overflow pipe 48, cold water pipe 441, hot-water line 462 and water inlet pipe 42; The water inlet of taking the outlet valve 46 of water pipe 461 out of is connected to and mixes water pipe 464, mix between water pipe 464 and the hot-water line 462 and be connected to check valve 463, mix between water pipe 464 and the connecting leg 451 and join with tapping pipe 452, the internal diameter of tapping pipe 452 is less, in order to avoid tapping pipe causes the short circuit in water route to the hot water channel; Be provided with the stop valve 1 that uses as inlet valve between connecting leg 451 and the water inlet pipe 42, the spilling water valve between the by-pass valve control between connecting leg 451 and the cold water pipe 441, cold water pipe 441 and the overflow pipe 48 is integrated in the switching valve 9.In conjunction with Fig. 4 as seen, expander 43 is made of shell 51, bearing 53, diaphragm 52 and spring 57, diaphragm 52 is sandwiched between shell 51 and the bearing 53, diaphragm and shell surround inner chamber 510, diaphragm 52 central authorities as expansion wall are fixed with the controll block 56 that tooth bar is established in both sides, the switch block 54 and 55 of corresponding conversion valve 9 and stop valve 1 stretches in the inner chamber 510 meshing with the tooth bar of controll block 56 both sides respectively respectively, the delivery port of stop valve directly communicates with inner chamber 510, water supply 511 on the shell communicates with connecting leg 451 (Fig. 3), and screw 58 is used for the elastic force of regulating spring 57.Close outlet valve 46 back expanders and be transformed into state shown in Figure 5 from Fig. 4 state, in its process, diaphragm 52 drives on the controll block 56 and moves, switch block 55 clockwise rotates, and switch block 54 rotates counterclockwise, and when the expansion amplitude of diaphragm 52 was excessive, sharp perverse 531 on the bearing was with its perverse wearing.
