Explanation.
Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
See the structural representation that Fig. 1, Fig. 1 are gas heater first embodiments of the present invention.
The gas heater that the present embodiment is provided, it includes burner 12, and is that burner 12 is for flammable
The air inlet pipeline 13 of gas, with the heat exchanger 10 of water inlet pipe 14 and outlet pipe 15, and for burning
Device 12 and heat exchanger 10 discharge the smoke pipe 11 of waste gas.Described burner 12 is for heat exchanger 10
Heating, heat exchanger 10 is used for the current flowed through in heat exchanger 10 pipeline are carried out heat exchange process,
Thus realize current are heated.When gas heater uses complete, water inlet pipe 14 is closed, now
Although having cut off the supply channel of gas heater, but pipeline also remains water.Certain areas daily
With in water containing more calcium, magnesium ion, water hardness is higher, when gas heater idle time relatively
Time long, the water in pipeline the most easily produces incrustation scale and coheres on tube wall, thus reduces combustion
The heat exchange efficiency of gas water heater, in the pipeline closed, the long-time water stood also can breed bacteria, special
It not that the hot water water quality of its output is poor, easily makes the health of user when gas heater just starts
Become impact.Additionally, the water accumulated in for a long time in pipeline also can corrosion pipeline, such as, copper material system
The water pipe become is easily generated Aerugo (patina), not only can reduce the heat exchange efficiency of gas heater, also can reduce
The service life of gas heater.
In order to prevent the water flowing tube wall of gas heater from generating incrustation scale and prevent ventilating water pipe by hydrops corrosion,
The gas heater of the present embodiment also includes pipeline drainage arrangement, when gas heater uses complete, logical
Cross this pipeline drainage arrangement to be drained by the water of residual in gas heater pipeline, thus reach to prevent incrustation scale raw
Become and protection pipeline is not by the purpose of corrosion.Specifically, this pipeline drainage arrangement includes that controller is (in figure
Not shown), electromagnetic valve 20 and air pump 30, according to the water inlet direction of water inlet pipe 14 on this water inlet pipe 14
Setting gradually electromagnetic valve 20 and air pump 30, the exhaust passage of air pump 30 connects with water inlet pipe 14, electromagnetic valve
20 are used for closing and turn on water inlet pipe 14, and controller electrically connects with electromagnetic valve 20 and air pump 30 respectively, control
Device processed is used for the control instruction according to user or the working state control electromagnetic valve 20 according to gas heater
With opening or closing of air pump 30.Under normal circumstances, the Starting mode of pipeline drainage arrangement includes two kinds:
Starting mode one, after gas heater uses, user can be arranged on control panel by pressing
The drain button at place carrys out primer liner drainage arrangement；Starting mode two, when gas heater use complete time
Or when gas heater uses complete Preset Time (such as, 2 seconds, 3 seconds or any suitable pre-
If the time) after, pipeline drainage arrangement starts automatically.When pipeline drainage arrangement starts, controller controls
Electromagnetic valve 20 cuts out water inlet pipe 14, and controls air pump 30 and start water inlet pipe 14 is carried out air blast,
Water in pipeline discharges under strong wind action, such as, is discharged by the gondola water faucet of connection outlet pipe 15,
Air pump 30 continues to water inlet pipe 14 air blast a period of time, by pipeline Quick-air-drying, to keep the dry of pipeline
Dry and cleaning, thus prevent the hydrops in pipeline from producing incrustation scale on tube wall, and play the work protecting pipeline
With, improve the heat exchange efficiency of gas heater, it is ensured that the hot water safety and Health of gas heater output,
Also extend the service life of gas heater.
Further, as it is shown in figure 1, under the normal mode of operation of gas heater, at electromagnetic valve 20
Hydraulic pressure in conducting state, water inlet pipe 14 is relatively big, in order to prevent the water in water inlet pipe 14 from passing through air pump
In connecting pipeline reflux air intake pump 30 between 30 and water inlet pipe 14, between air pump 30 and water inlet pipe 14
Connecting pipeline on be additionally provided with check valve 23, this check valve 23 allows the air-flow of air pump 30 toward water inlet pipe 14
Side is passed through, and stops the current direction air pump 30 of water inlet pipe 14 side, thus reaches to protect the mesh of air pump 30
's.
In the present embodiment, gas heater is applied not only to take a shower, it is also possible at the outlet pipe of gas heater
Multiple way union with several taps is installed, it is achieved the central water supply of gas heater, example at 15
As, the hot water of gas heater is tapped into kitchen or washing room, thus improves making of gas heater
By rate.For this gas heater with complicated delivery pipeline, original outlet pipeline is difficult to
Meet the requirement of air blast draining, in order to improve the drainage effect of gas heater, simultaneously will not be to its water outlet
Pipeline impacts, such as, shown in Fig. 1, pipeline drainage arrangement also includes drain pipe 16 and Electrocontrolled tee valve
24, controller electrically connects with this Electrocontrolled tee valve 24, and one end of drain pipe 16 is via Electrocontrolled tee valve 24
Connect with outlet pipe 15, i.e. can turn mutually to realize two by controlling the commutation of this Electrocontrolled tee valve 24
The water stream channel changed, wherein, after gas heater uses, controller controls to be positioned at water inlet pipe 14
The electromagnetic valve 20 at place cuts out water inlet pipe 14, controls Electrocontrolled tee valve 24 and turns on drain pipe 16 and close
Close outlet pipe 15, and control air pump 30 and start water inlet pipe 14 carries out air blast, now, blast into
Under air effect in water pipe 14, the water in gas heater pipeline is discharged by the drain pipe 16 of conducting,
Discharge thus without the water in the delivery pipeline that will connect with outlet pipe 15, also will not be because of delivery
Water valve on pipeline close and cannot draining, drainage effect is more preferable, and drainage procedure need not manually participate in,
Simple and convenient, thus prevent the hydrops in pipeline from producing incrustation scale on tube wall, and play the work of protection pipeline
With, improve the heat exchange efficiency of gas heater, it is ensured that the hot water safety and Health of gas heater output,
Also extend the service life of gas heater.
See the structural representation that Fig. 2, Fig. 2 are gas heater the second embodiments of the present invention.
