Abstract

The utility model relates to a fuel gas appliance in life, in particular to a diaphragm pressure fuel gas-steam heater, including a housing, a heat exchanger, a water valve, a fuel gas valve, an inflamer and a petticoat pipe. An electromagnetic valve is arranged between the inlet pipe of the heat exchanger and the valve. The high temperature pipe at the outlet end is connected with a diaphragm pressure conversion valve. The lower end is respectively provided with a hot water outlet and a steam outlet to separate the generated steam from hot water. The phenomenon of scalded by steam can not occur when in use a steam bath or a hot water bath. The utility model has the advantages of simple and reasonable structure, convenient installation, use and maintenance.

Description

Mould formula combustion and steam water heater

Technical field:

The utility model relates to gas appliance in the life, more particularly, is mould formula combustion and steam water heater.

Background technology:

In the prior art, the function ratio of gas heater is more single, just based on bathing, makes troubles to the user at arctic weather; China Patent No. 98205417.3 discloses " safety-type steam heated water heater "; China Patent No. 96248918.2 discloses " can produce the water heater of steam "; Producing steam with water heater to heat up to the bathroom; The method that adopts is at the water valve in-core water channel to be reduced to shunt; This scenario-frame complexity, job insecurity, wayward, dry-fire condition is serious, and steam and hot water flow out from same outlet simultaneously, scald easily in the conversion of steam and hot water.

Summary of the invention:

Problem to be solved in the utility model be overcome deficiency of the prior art and provide that a kind of security is good, simple in structure, installation and maintenance and use all mould formula combustion and steam water heater easily.

The utility model technical scheme that is adopted of dealing with problems is achieved in that the utility model includes housing, heat exchanger, water valve, gas valve, burner and petticoat pipe; Gas valve and water valve link, and communicate with burner; The heat exchanger upper end is mounted with petticoat pipe, and the lower end connects with burner; Be connected with magnetic valve between water valve and the heat exchanger; Be connected with the mould switching valve on the high temperature pipe of water side, its lower end is respectively hot water outlet and steam (vapor) outlet, forms double outlet structure; Have between the A chamber of mould switching valve and the B chamber and take over a business separation greatly, take over a business to have valve rod greatly and run through valve body, be associated with two spools on the valve rod, be respectively steam spool and hot water spool.

The water inlet end of water valve is connected with high-pressure conduit, and communicates with the A chamber of mould switching valve; On the pipeline of high-pressure conduit, be connected with normally open valve and normally close valve; Between the intake antrum of magnetic valve and the water chamber hole of damming is arranged, the aperture is the 0.8-2.0 millimeter; The C chamber of water valve and the water chamber of magnetic valve are provided with connecting pipe.

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

1. the utility model is owing to be connected with magnetic valve between water valve and heat exchanger; The mould switching valve is adopted in the water side, 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.

2. the utility model utilizes the pressure of water to control turning to of mould switching valve, simplifies the structure, and has improved stability.

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

Description of drawings:

Fig. 1 is the utility model mould formula combustion and steam water heater schematic diagram;

Fig. 2 is that the utility model water valve connects schematic diagram with mould switching valve pipeline;

The specific embodiment:

Referring to Fig. 1,2, present embodiment includes housing 1, petticoat pipe 2, heat exchanger 3, water inlet pipe 4, connecting pipe 5, magnetic valve 6, water inlet 7, water valve 8, gas valve 9, fuel gas inlet 10, mould switching valve 11, hot water outlet 12, steam (vapor) outlet 13, steam vent 14, normally open valve 15, normally close valve 16, burner 17, high-pressure conduit 18, high temperature pipe 19, takes over a business 20 greatly, A chamber 21, B chamber 22, hot water spool 23, steam spool 24, push rod 25, take over a business 26 for a short time, C chamber 27, D chamber 28, water chamber 29, hole 30 and intake antrum 31 dam; Gas valve 9 communicates with burner 17; Heat exchanger 3 upper ends are mounted with petticoat pipe 2, and the lower end connects with burner 17; On the pipeline between water valve 8 and the heat exchanger 3, be connected with magnetic valve 6; Be connected with mould switching valve 11 on the high temperature pipe 19 of water side, its lower end is respectively hot water outlet 12 and steam (vapor) outlet 13; Have between the A chamber 21 of mould switching valve 11 and the B chamber 22 and take over a business 20 greatly and separate, take over a business 20 greatly and have valve rod 25 and run through valve body, be associated with two spools on the valve rod 25, be respectively hot water spool 23 and steam spool 24; The water inlet end of water valve 8 is connected with high-pressure conduit 18 and communicates with the A chamber 21 of mould switching valve 11; On the pipeline of high-pressure conduit 18, be connected with normally open valve 15 and normally close valve 16; Between the intake antrum 31 of magnetic valve 6 and the water chamber 29 hole of damming 30 is arranged, the aperture is the 0.8-2.0 millimeter; The C chamber 27 of water valve 8 is provided with connecting pipe 5 with the water chamber 29 of magnetic valve 6.

When using shower, cold water through water inlet 7, water valve 8, magnetic valve 6, enter heat and change and hand over device 3, water valve 8 and gas valve 9 interlocks, starting ignition system (not drawing among the figure); Combustion gas enters burning in the burner 17, and heated hot water flows out from hot water outlet 12 through mould switching valve 11, and is for people to use.

When using steam bath, close magnetic valve 6 and normally open valve 15, open normally close valve 16, water enters the D chamber 28 of water valve 8 through water inlet 7, and water pressure pushing is taken over a business 26 for a short time and is moved the starting ignition device to C chamber 27 directions; A spot of water enters by the hole 30 of damming and adds thermosetting steam in the heat exchanger 3 simultaneously; The water at water inlet 7 places enters the A chamber 21 of mould switching valve 11 by high-pressure conduit 18, pressure promotes to take over a business greatly 20 and moves to B chamber 22 directions, air in the B chamber is discharged by steam vent 14, take over a business 20 greatly and drive valve rod 25, open steam spool 24, close hot water spool 23, high-temperature steam is from steam (vapor) outlet 13 ejections; When the water route occur to be blocked, the pressure at water chamber 29 places raises, and connecting pipe 5 imports C chamber 27 with pressure, and at this moment the pressure in C chamber 27 and D chamber 28 reaches balance, takes over a business 26 for a short time and moves to C chamber 27 directions, closes ignition system, the work of water heater stop.
