Abstract
The utility model discloses a double gas-supply water heater, comprising a shell and a heater in the shell. The shell is provided with a cold water port and a water flow detection device at the cold water port. A power supply switch for starting a pulse lighter is arranged on the water flow detection device. The heater comprises a fire control change-over valve, a gas nozzle and a burner which are connected in turn by gas delivery pipes. A plurality of gas nozzles are arranged on the fire control change-over valve in parallel. The gas nozzle comprises two gas outlets of different diameters, one gas outlet flexibly arranged under the gas pressure and capable of being closed or opened. A heat exchanger heated by the burner is connected with the cold water port by a water pipe. The double gas-supply water heater uses different gas as the combustion gas supplies to bring great convenience for the user.
Description
Technical field
The utility model relates to a kind of dual gas supply water heater, particularly a kind of can be with the dual gas supply water heater of different gas kinds as fuel gas source.
Background technology
More and more as the kind of fuel gas source at present, but the structural requirement of its burner of gas kind difference is also different, water heater on the market generally all is that single gas kind is as fuel gas source, can not change fuel gas source, this user makes troubles, and will change water heater and cause the wasting of resources like this when replacing fuel gas source.
The utility model content
For solving the problems referred to above that prior art exists, the utility model provides a kind of dual gas supply water heater, and it can be with two kinds of different gas kinds as fuel gas source, and self can make a choice according to the difference of input gas kind.
The utility model can be solved by the following technical programs:
A kind of dual gas supply water heater of the utility model, this water heater comprises a shell and places the heater of enclosure, described shell is established a cold water outlet, one current checkout gear places described cold water outlet place, establish the power switch of a starting impulse igniter on the described current checkout gear, described heater comprises the fire control switching valve that connects by appendix successively, gas nozzle, burner, described gas nozzle number is a plurality of and places on the described fire control switching valve, described gas nozzle concrete structure is they two gas outlets that comprise different apertures, and a head can seal or open one of them described gas outlet under gas pressure; Also comprise a heat exchanger by described burner heating, heat exchanger links to each other with described cold water outlet by water pipe.
The utility model comprises that also a temperature inductor and a flame detect inductive needle, and described temperature inductor and flame detect the signal of inductive needle detection and passes to described pulse igniter.
Since adopt above technical scheme, a kind of dual gas supply water heater of the present utility model, and its structure by gas nozzle can be selected gas port automatically, therefore reaches the purpose of using different gas kinds.
Description of drawings
Fig. 1 is the concrete structure figure of the utility model dual gas supply water heater
Fig. 2 is the structure chart of gas nozzle of the present utility model and fire control switching valve
Among the figure 1, temperature inductor; 2, flame detects inductive needle; 3, pulse igniter; 4, the gas transmission electromagnetic valve; 5, housing; 6, motor; 7, exhaust fume collecting hood; 8, heat exchanger; 9, the fire control switching valve; 10, burner; 11, the current checkout gear; 12, power switch; 13, cold water inlet; 14, gas inlet; 15, gas nozzle.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model:
As shown in Figure 1, a kind of dual gas supply water heater of the utility model, this water heater comprises a shell 5 and places the heater of enclosure, shell 5 is established a cold water outlet 13, one current checkout gear 11 places the cold water outlet place, establish the power switch 12 of a starting impulse igniter 3 on the current checkout gear 11, heater comprises the burner 10 that connects by appendix successively, gas nozzle 15, fire control switching valve 9, gas nozzle 15 numbers are a plurality of and place (as shown in Figure 2) on the fire control switching valve 9, this fire control switching valve can be controlled the number that gas nozzle is given vent to anger as required, successively the size of control fire.The gas nozzle concrete structure is they two gas outlets that comprise different apertures, and a head can seal or open one of them described gas outlet under gas pressure; Also comprise a heat exchanger 8 by burner 10 heating, and heat exchanger 8 can be placed burner 10 tops, the water pipe that heat exchanger 8 links to each other with cold water outlet 13 continuous and with the water pipe multi-turn around its periphery.Also comprise an exhaust fume collecting hood 7 that links to each other with motor 6 that places the shell inner top.Comprise that also a temperature inductor 1 and a flame detect inductive needle 2, temperature inductor 1 and flame detect the signal of inductive needle 2 detections and pass to pulse igniter 3.
Its operation principle is: cold water enters water heater by cold water inlet 13; the current checkout gear 11 of flowing through; under the effect of circulating water certain pressure difference; promote the valve on the current checkout gear 11; and promotion simultaneously is installed in the power switch 12 on the current checkout gear 11; with power connection and starting impulse igniter 3; meanwhile open gas transmission electromagnetic valve 4; combustion gas is by fuel gas inlet 14; the current checkout gear 11 of flowing through; fire control switching valve 9; gas kind nozzle 15; enter burner 10; because natural gas and liquefied gas admission pressure exist than big-difference; gas kind nozzle 15 is selected the aperture of pore according to the difference of pressure; continue igniting automatically by pulse igniter 3; till successfully entering normal operating conditions up to lighting a fire; cold water enters in the coil pipe of heat exchanger 8 simultaneously; rely on the big calorimetric of emitting in the fuel gas buring process to heat; the waste gas that produces in the combustion process is then collected by exhaust fume collecting hood 7 and is discharged outdoor by motor 12; when water heater lack of water or hydraulic pressure deficiency occur in the course of work or ignition process; short of electricity; lack combustion gas; the hot water temperature is too high; when accident is put out phenomena of the failure such as fire; pulse igniter will detect inductive needle 2 by flame; the signal of temperature inductor 1 feedback; automatically cut off the electricity supply; reply original normally close valve state at once under the situation that the short of electricity of gas transmission electromagnetic valve 4 is supplied with, cut off fuel gas path and play the safeguard protection effect.
Based on said structure, a kind of dual gas supply water heater of the present utility model can be with different gas kinds as fuel gas source, and it brings great convenience for the user.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
