Description

Water heater

Technical field

The present invention relates to a kind of water heater, particularly relate to the structure of water heater.

Background technology

China's most area water quality is all partially hard, and impurities in water is more, and water heater uses due to long-time, will in inner bag Slowly the many incrustation scales of accumulation, affect using effect.Although magnesium rod has all been put in inner bag in producer, reducing the generation of incrustation scale, but Effect is not fine.User needs to be cleaned inner bag in time blowdown process.The time that water heater cleans is generally 2 to 3 Year.Often not cleaning to be easily caused and heating pipe attachment incrustation scale electric leakage, even have the possibility that blast occurs, water heater is not due to for a long time Cleaning can cause water turbidity, water temperature not high and shorten water heater life-span；If irregularly cleaning, water heater will shorten the longevity Life, reduces its use value, it is impossible to give full play to its effect, and the electrical heating time lengthens, and can accumulate sediment in inner bag, in reducing The dischargeable capacity of courage, makes the water of inner bag reduce, and water cooling is fast, and water quality also can be contaminated, therefore, it is necessary to fixed to water heater liner Phase cleans, with scale removal and sediment, in view of this, it is necessary to improved existing water heater to solve

Certainly the problems referred to above.

Content of the invention

It is an object of the invention to provide a kind of water heater, it has the design of improved structure, can effectively prevent in inner bag The continuous generation of incrustation scale, simultaneously convenient to install and maintain, low cost.

For achieving the above object, a kind of water heater of the present invention, comprising: inner bag, thermal source, inner bag water inlet, inner bag go out The mouth of a river, plate type heat exchanger, flow control valve, circulating pump, water flow switch, control line, inner bag outlet pipe, inner bag water inlet pipe, water source Outlet pipe, water source water inlet pipe, threeway vent valve, check valve, safety valve, three-way connection, water source water intaking valve, water source outlet valve.In Courage water inlet passes through flow control valve, circulating pump, inner bag water inlet pipe, check valve, threeway vent valve connecting plate type heat exchanger, inner bag Delivery port passes through inner bag outlet pipe connecting plate type heat exchanger, and water source water intaking valve passes through water source water inlet pipe, water flow switch connecting plate type Heat exchanger, water source outlet valve passes through water source outlet pipe connecting plate type heat exchanger, and water flow switch controls circulating pump by control line, Inner bag water inlet pipe and water source water inlet pipe are provided with three-way connection, and two three-way connections are connected by safety valve.

Compared with prior art, the invention has the beneficial effects as follows: the water in water heater liner need not be changed for a long time, in inner bag The impurity such as incrustation scale also just will not increase always, water heater liner and heating tube lifetime are not affected by incrustation scale.

Brief description

Fig. 1 is the schematic diagram of water heater one detailed description of the invention of the present invention.

In figure: 1 inner bag, 2 thermals source, 3 inner bag water inlets, 4 inner bag delivery ports, 5 plate type heat exchangers, 6 flow control valves, 7 follow Ring pump, 8 threeway vent valves, 9 check valves, 10 safety valves, 11 water flow switches, 12 control lines, 13 water source water intaking valves, 14 water source water outlets Valve, 15 inner bag outlet pipes, 16 inner bag water inlet pipes, 17 water source outlet pipes, 18 water source water inlet pipes, 19 three-way connections, 20 three-way connections.

Detailed description of the invention

Fig. 1 show a detailed description of the invention of water heater of the present invention, and this water heater includes 1 inner bag, 2 thermals source, 3 inner bags Water inlet, 4 inner bag delivery ports, 5 plate type heat exchangers, 6 flow control valves, 7 circulating pumps, 8 threeway vent valves, 9 check valves, 10 safety Valve, 11 water flow switches, 12 control lines, 13 water source water intaking valves, 14 water source outlet valves, 15 inner bag outlet pipes, 16 inner bag water inlet pipes, 17 Water source outlet pipe, 18 water source water inlet pipes, 19 three-way connections, 20 three-way connections.

Water heater structure: inner bag water inlet (3) is by flow control valve (6), circulating pump (7), inner bag water inlet pipe (16), list To valve (9), threeway vent valve (8) connecting plate type heat exchanger (5), inner bag delivery port (4) passes through inner bag outlet pipe (15) connecting plate Formula heat exchanger (5), water source water intaking valve (13) passes through water source water inlet pipe (18), water flow switch (11) connecting plate type heat exchanger (5), water Source outlet valve (14) passes through water source outlet pipe (17) connecting plate type heat exchanger (5), and water flow switch (11) is controlled by control line (12) Circulating pump processed (7), is provided with three-way connection (the 19th, 20) on inner bag water inlet pipe (16) and water source water inlet pipe (18), and two three connect Head (the 19th, 20) connects water source water inlet pipe (18) and inner bag water inlet pipe (16) by safety valve (10).

Inner bag water filling flow process before water heater working: close water source outlet valve (14), open threeway vent valve (8), open water Source water intaking valve (13) water enters water source water inlet pipe (18) and enters inner bag water inlet pipe (16) from inner bag water inlet by safety valve (10) (3) enter inner bag (1), after filling water, exit into inner bag outlet pipe (15) again through plate type heat exchanger from inner bag delivery port (4) (5) flowing out from air bleeding valve (8), water fills, and is then shut off threeway vent valve (8), opens water source outlet valve (14), and flow process completes； The effect of check valve (9) is the refluence preventing water before inner bag (1) fills water, affects water filling.

Water heater working flow process: after thermal source (2) heated the inner water of inner bag (1), cold water flows into from water source water intaking valve (13) Water source water inlet pipe (18) goes out from water source outlet pipe (17) water source through water flow switch (11) after plate type heat exchanger (5) heat exchange again Hot water after water valve (14) outflow heat exchange, water flow switch (11) starts circulating pump (7) by control line (12), and inner bag (1) is inner Hot water starts to flow out from inner bag delivery port (4), flow into inner bag outlet pipe (15) by after plate type heat exchanger (5) heat exchange again through interior Courage water inlet pipe (16), circulating pump (7), flow control valve (6), inner bag water inlet (3), cold water flows back to inner bag (1), so circulates.

Owing to the internal mode using plate type heat exchanger heat exchange of water heater heats the domestic waters such as bathing, water heater liner In water be in water heater inner loop, it is not necessary to change, the incrustation scale in inner bag just will not increase, and has reached to clean heat The purpose of hydrophone.
