Description

Gas burning steam water heater

The utility model relates to a kind of combustion and steam device.

" multifunctional fuel water heater and water boiler " patent that I obtained in nineteen ninety develops the gas heater technology widely, has improved, but still has weak point, exactly: fail directly to produce high-temperature steam to possess more multipurpose.

The utility model purpose provides a kind of water heater that can produce hot water, boiling water and steam--combustion and steam water heater, uses for bathroom, kitchen and production site.

The utility model is achieved in that it is that the base growth improvement forms with existing gas heater and multifunctional fuel water heater and water boiler.It has protecgulum (1), bonnet (2), combustion chamber (3), heat exchanger (4), main burner (5), gas valve (6), ignition switch (7), thermocouple safety device (8), cold valves (9), high-temperature heat exchanger (10), blender (11), cold water branch valve (12) and thermometer (13).Add steam security valve (14) in the blender upper end.In the loop of thermocouple safety device, be connected with thermoswitch (15) (as accompanying

drawing

2,5,6).Cancel the pressure solicitating film (10) of the cold valves of existing gas heater and multifunctional fuel water heater and water boiler, cancelled catch bar (20) and valve closing device (21) (as accompanying drawing 1) between cold valves and the gas valve.Gas valve directly and main burner communicate and cut off (as accompanying drawing 2) with cold valves fully.

Safety valve obtained in Patent right multifunctional fuel hot water, the boiler at me,, needn't establish safety valve, and the utility model requires production steam to need with producing for civilian, so need be set owing to there is not the higher steam of pressure.Simultaneously, for the gas heater of producing steam, requirement is a kind of total pressure gas heater, there is certain discharge just can under any hydraulic pressure, carry out work, again can automatic disconnection combustion gas in several seconds in water-stressed conditions, and when recovering normal water inlet, can in several seconds, recover automatically to burn, so, in the loop of thermocouple safety device, connect (serial or parallel connection) thermoswitch.The pressure solicitating film of cold valves in existing general gas water heater of cancellation simultaneously and the multifunctional fuel water heater, catch bar and valve closing device between cancellation cold valves and the gas valve.Gas valve directly and main burner communicate and cut off fully with cold valves.

When lack of water, be connected between gas valve and the thermocouple and be contained in thermoswitch on the heat exchanger be heated open circuit (as Fig. 4) or short circuit (as Fig. 5), make the down circuitry of thermocouple, order about thermocouple and close valve automatically, burn-out.When recovering water inlet, heat exchanger is caught a cold, and thermoswitch also is subjected to cold reset, and connect the loop thermocouple driving valve is opened, and allows combustion gas enter burning, recovers operate as normal.Become a kind of total pressure gas heater, and can produce boiling water and steam continuously.As long as drive atmos-valve, the water temperature by heat exchanger and high-temperature heat exchanger is up to 100 ℃, and water yield is about 3 kilograms of per minutes.When turning water valve down and make the water yield reduce to certain value, can produce the high-temperature steam about 110 ℃.When a large amount of steam of continuous generation, but steamed rice, bag, cake, ground rice and as the steam of sauna bath and on industrial production required steam.

If there are not the construction features of above-mentioned total pressure work, when then inflow reduced to certain value, fire promptly extinguished, and can't be heated into high-temperature steam to water.

For the ease of using, shunt valve (16) is housed at the blender delivery port.

For safe water vapour, in the utility model, also can adorn red, green indicator lamp, play the warning effect.The cold water branch valve is connected with the circuit of the red indicator lamp of Synchronization Control (17) with green indicator lamp (18).When pulling the cold water branch valve to the closed position, no cold water flows into blender, and in the blender is steam or boiling water, just when pulling to the closed position, has connected the red light circuit synchronously to the cold water branch valve, and red light is bright, points out.On the contrary, when pulling the cold water branch valve to the enable possition, cold water flows into blender, just obtains the hot water through temperature adjustment, just when pulling to the enable possition, has connected the green light circuit synchronously to the cold water branch valve, and green light is bright, and red light extinguishes.And control circuit red, green light is a kind of common prior art, and this specification omits circuit diagram.

The utility model has the advantages that: energy manufacture hot water, boiling water and production steam, can regulate hot water temperature and quantity of steam, can indicate water, stripping temperature and warning.Can discharge automatically when air pressure is too high.As long as it has certain discharge, just can under any hydraulic pressure, carry out work, again can automatic disconnection combustion gas in several seconds when lack of water, when recovering normal water inlet, in several seconds, recover burning automatically.The utility model is all useful throughout the year.In addition, when consuming under the gas quantity situation identical with general gas heater air consumption, the same temperature hot water amount that it obtained is Duoed more than one times than general water heater.It is widely used in bathroom, kitchen and production site.

Further specify below in conjunction with the accompanying drawing example illustrated.

Fig. 1 is the gas valve of general gas water heater and multifunctional fuel water heater and water boiler and the organigram between the cold valves;

Fig. 2 is that the master that the utility model is removed behind the protecgulum looks schematic diagram;

Fig. 3 is the A-A cross-sectional schematic of Fig. 2;

Fig. 4 is that profile master of the present utility model looks schematic diagram;

Fig. 5 is that thermoswitch is connected on the schematic diagram in the thermocouple safety device loop.

Fig. 6 is that thermoswitch is connected in parallel on the schematic diagram in the thermocouple safety device loop.

Embodiment one,

As Fig. 2-5, thermoswitch is connected in the thermocouple safety device loop.Earlier put into cold water by cold valves (9), open gas valve (6) and ignition switch (7) then, main burner (5) is lighted, the heating of the cold water of inflow heat exchanger (4), hot water or boiling water or steam flow out from the water heater lower end.As unexpected lack of water appears, and heat exchanger temperature raises, and thermoswitch (15) is opened a way immediately, cuts off thermocouple safety device (8) loop current, and gas valve is promptly closed, burn-out.When recovering water inlet, no matter the hydraulic pressure size as long as flow is normal, descends conduit temperature, thermoswitch is compound, recovers burning.When vapour pressure surpasses setting, can discharge from steam security valve (14) automatically.

The label of other structures is among the figure: protecgulum (1), bonnet (2), combustion chamber (3), high-temperature heat exchanger (10), blender (11), cold water branch valve (12), thermometer (13), shunt valve (16), red indicator lamp (17), green indicator lamp (18).

Embodiment two,

As Fig. 2,3,4 and 6, thermoswitch is connected in parallel in the thermocouple safety device loop.This example is with the difference of embodiment one: as unexpected lack of water appears, heat exchanger temperature raises, and thermoswitch (15) demand working causes the short circuit of thermocouple safety device loop current with the ground wire contact, the magnetoelectricity switch loses electric current and cuts out gas valve, burn-out voluntarily.When recovering water inlet, no matter the hydraulic pressure size as long as flow is normal, descends conduit temperature, thermoswitch is replied open-circuit condition, the no longer short circuit but reply and the energising of magnetoelectricity switch is inhaled open, recover combustion gas and enter burning of thermocouple loop current.Other partly, and is all identical with embodiment one.
