The utility model is characterized in that a heating unit (12) is arranged in the water tube (14). The utility model which has the functions of both gas and electricity water heaters is not controlled by water pressure and volume of a water storage linear, energy saving, high in efficiency, low in cost and convenient for use.

Description

The dual-purpose water heater of combustion gas and electricity

One, technical field

The utility model relates to a kind of water heater, especially has the water heater of combustion gas and two kinds of functions of electricity.

Two, background technology

At present, the water heater of selling on the market by using the energy to classify, can be divided into two big classes, i.e. electric heater and gas heater, and electric heater need be by adorning water storage liner, and volume is bigger, and the water storage volume is limited; Gas heater needs hydraulic pressure to reach one and just can not use regularly could use, as be lower than the required hydraulic pressure of the right hydrophone of combustion gas the time.

Three, summary of the invention

The purpose of this utility model provides a kind of both available combustion gas, but the dual-purpose water heater of electricity consumption again solve in use the hydraulic pressure deficiency and can not use gas heater, solve the big and limited problem of storage water space of water storage liner volume of electric heater again.

Concrete scheme of the present utility model is: burnt gas switch is installed in the preceding left side of shell, throughput control valve, air inlet, Water flow adjusting valve, water inlet are installed in the lower end of exchanging air, power switch and attaching plug be installed in the preceding right side of shell, burner, pulse firing pin, on the top of throughput control valve, water pipe is on heat exchanger, and smoke guiding cover is the top on shell.It is characterized in that being equipped with in the water pipe heater, the skin of heater has exhausted source layer.

Adopt the dual-purpose water heater of such scheme, have two kinds of functions using combustion gas and electricity, not limited by hydraulic pressure, also be not subjected to the restriction of water storage liner volume, the efficient height, expense is low, and is easy to use.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the A-A cutaway view of Fig. 1.

Five, specific embodiments:

From Fig. 1, Fig. 2 as can be known, the utility model is installed in the preceding left side of shell 16 by right device switch 1, throughput control valve 3, air inlet 4, Water flow adjusting valve 5, water inlet 6 are installed in the lower end of exchanging air 11, power switch 7 and attaching plug 10 are installed in preceding right side, burner 8, the pulse firing pin 9 of shell 16, on the top of throughput control valve 3, water pipe 14 is on heat exchanger 11, smoke guiding cover 15 is the top on shell 16, it is characterized in that being equipped with in the water pipe 14 heater 12.It is characterized in that: the skin of heater 12 has exhausted source layer 13.

Operation principle: when water heater need use combustion gas, should shut power switch 7, take off attaching plug 10, open burnt gas switch 1, because the effect of hydraulic pressure, pulse firing pin 9 ignition combustion devices 8, exchanging air 11 heating pipes 14, hot water outlet 2 begin to flow out hot water simultaneously, just can use.When water heater makes electricity consumption, shut burnt gas switch 1, open water intaking valve, make in the water pipe 14 and be full of cold water, the plug 10 that plugs in turns on the power switch 7, owing in the water pipe 14 heater 12 is installed, the skin of heater 12 is exhausted source layers 13, when energising, water can be not charged, guaranteed the safety of using, be full of water between water pipe 14 and the exhausted source layer 13, make electric energy change the thermal energy transfer feedwater into by heater 12.Like this, just can use hot water, and safety, power consumption is lower, and it is fast to conduct heat, can energy savings.Out of use the time, shut burnt gas switch 1 and power switch 7 simultaneously, and attaching plug 10 is taken out in socket.

Claims (2)

1. the dual-purpose water heater of combustion gas and electricity, burner switch (1) is installed in the preceding left side of shell (16), throughput control valve (3), air inlet (4), Water flow adjusting valve (5), water inlet (6) is installed in the lower end of exchanging air (11), power switch (7) and attaching plug (10) are installed in the preceding right side of shell (16), burner (8), pulse firing pin (9), top in throughput control valve (3), water pipe (14) is on heat exchanger (11), smoke guiding cover (15) is characterized in that being equipped with in the water pipe (14) heater (12) on the last top of shell (16).
