Between the D chamber of fine motion water valve and the water chamber micropore is set, its aperture is at the 0.8-2.0 millimeter: be provided with the valve pocket pipe between C chamber and the water chamber; Have between the A chamber of reversal valve and the B chamber to take over a business greatly and separate, have valve rod on taking over a business greatly and run through valve body, be associated with two spools on the valve rod, be respectively steam spool and hot water spool with macromesenterium.

The high-pressure conduit that connects on the pipeline between main water valve and the water flow sensor, and communicate with the A chamber of reversal valve; Be connected with low-pressure tube on the water inlet pipe of heat exchanger, and communicate with the B chamber of reversal valve.

The utility model compared with the prior art, beneficial effect is embodied in:

1. the utility model forms the structure that two-way supplies water owing to be connected with two water routes respectively on the Y-pipe between water inlet interface and the heat exchanger; Easy to use, safe and reliable.

2. the utility model adopts the reversal valve structure, and steam and the hot water that produces is separated, and when using steam bath or hot bath, the phenomenon that steam scalds the people can not take place.

3. the utility model adopts fine motion water valve structure for the steam water route, and pressure regulator valve is set on the water route, has stablized hydraulic pressure, has optimized structure, improves the stability of supply steam.

4. simple in structure, cheap, installation and maintenance of the utility model and use all very convenient.

Fig. 2 is that the utility model reversal valve structure connects schematic diagram;

Fig. 3 is the utility model fine motion water valve structural representation;

The specific embodiment:

Referring to Fig. 1,2,3, present embodiment includes housing 1, petticoat pipe 2, heat exchanger 3, water inlet pipe 4, Y-pipe 5, main water valve 6, fine motion water valve 7, pressure regulator valve 8, water inlet interface 9, water flow sensor 10, gas valve 11, combustion gas interface 12, hot water outlet 13, steam (vapor) outlet 14, reversal valve 15, high-pressure conduit 16, low-pressure tube 17, burner 18, high temperature pipe 19, take over a business 20 greatly, macromesenterium 21, A chamber 22, B chamber 23, steam spool 24, hot water spool 25, valve rod 26, valve pocket pipe 27, micromesentery 28, C chamber 29, D chamber 30, intake antrum 31, water inlet 32, micropore 33 and water chamber 34; Gas valve 11 communicates with burner 18; Heat exchanger 3 upper ends are mounted with petticoat pipe 2, and the lower end connects with burner 18; Be respectively arranged with two water routes on the Y-pipe 5 of water inlet interface 9 and hot-water line 4, one is provided with water flow sensor 10 and main water valve 6, and another is provided with pressure regulator valve 8 and fine motion water valve 7, forms the structure that two-way supplies water; Be connected with reversal valve 15 on the high temperature pipe 19 of water side, its lower end is respectively hot water outlet 13 and steam (vapor) outlet 14.

Between the D chamber 30 of fine motion water valve 7 and the water chamber 34 micropore 33 is set, its aperture is at the 0.8-2.0 millimeter; Be provided with valve pocket pipe 27 between C chamber 29 and the water chamber 34; Reversal valve 15 has macromesenterium 21 and takes over a business 20 greatly and separate, and forms A chamber 22 and B chamber 23; Take over a business greatly to have valve rod 26 on 20 and run through valve body, be associated with two spools on the valve rod 26, be respectively steam spool 24 and hot water spool 25.

The high-pressure conduit 16 that connects on the pipeline between main water valve 6 and the water flow sensor 10, and communicate with the A chamber 22 of reversal valve 15; Be connected with low-pressure tube 17 on the water inlet pipe 4 of heat exchanger 3, and communicate with the B chamber 23 of reversal valve 15.

When using shower, cold water enters heat through water inlet interface 9, water flow sensor 10, main water valve 8 and changes in the friendship device 3, water flow sensor 10 has been sensed water and has been flowed, starting ignition system (not drawing among the figure), combustion gas enters burning in the burner 18, heated hot water flows out from hot water outlet 13 through reversal valve 15, and is for people to use.

When using steam bath, close main water valve 6; Start fine motion water valve 7 simultaneously, control valve 8 is controlled at hydraulic pressure under certain pressure, and water enters the D chamber 30 of fine motion water valve 7 through intake antrum 31 and water inlet 32, and water pressure pushing micromesentery 28 moves to C chamber 29 directions, the starting ignition device; A part of water is by micropore 33 throttlings simultaneously, and heating in Y-pipe 5 inflow heat exchangers 3 forms high-temperature steam; Because main water valve 6 cuts out, its both sides form pressure differential, and hydraulic pressure enters A chamber 22, the effect of macromesenterium 21 is taken over a business 20 greatly and is driven valve rod 26, promotes hot water spool 25 and steam spool 24, close the hot water channel, open steam channel, at this moment steam is from steam (vapor) outlet 14 ejections; When pipeline appearance obstruction, water chamber 34 places' hydraulic pressure of fine motion water valve 7 raise, and valve pocket pipe 27 imports C chamber 29 with pressure, and at this moment the pressure in C chamber 29 and D chamber 30 reaches balance, and micromesentery 28 moves to D chamber 30 directions, closes ignition system, the work of water heater stop.
