Description
Technical field
The utility model relates to gas heater field, relates in particular to a kind of gas water heater water road system.
Background technology
At present, China's domestic gas instantaneous water heater development is very fast, various in style, but its operation principle basic structure is roughly the same.Typical water heater generally comprises following components: shell, air-feeding-exhausting apparatus, burner, heat exchanger, air-control device, water-control device, gas linkage apparatus for gas and control system.
The effect of existing gas linkage apparatus for gas is to guarantee at hydraulic pressure enough, and when being introduced into heat exchanger and flowing, gas control valve just can be opened; And stop or during insufficient pressure, the air feed path that automatically cuts off combustion gas, prevents from burning out equipment because of lack of water i.e. usually said " water arrives, gas to " when current;
In order to realize the adjusting to temperature, in prior art, all by changing quantity combusted and air inflow, realize, although this mode can be applied smoothly in most of occasions, when the hydraulic pressure of subscriber household is too small, water heater often cannot normally be worked.When some occasion hydraulic pressure hour, because the existence of gas linkage apparatus for gas, only have hot water tap is reached to maximum, burner ability smooth ignition, and now because only opened hot water, even the aperture of burner is transferred to minimum, sometimes water temperature also can seem higher, directly bathing, so also need to open cold water faucet, the hydraulic pressure of hot and cold water tap in fact shares for user's water inlet pipe, when script user hydraulic pressure is just lower, cold water one has reduced the flow of hot water little, cause burner to be controlled and close by gas linkage apparatus for gas, just bathing smoothly of user like this, in prior art, to the adjusting of water temperature, be all to realize by adjusting the aperture of burner and changing cold water flow, in the situation that burner aperture is minimum, in existing gas heater, also cannot solve problems.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of gas water heater water road system of unsteady flow temperature adjustment, when user's discharge too low, burner reaches minimum of a value leaving water temperature when still too high, controller is just controlled by the aperture to magnetic valve, open the path of water inlet pipe branch road, to guarantee normally bathing of user, improved the range of application of water heater, make water heater more be adapted at condition poor, the district work that hydraulic pressure is lower.
The utility model is achieved in that a kind of gas water heater water road system of unsteady flow temperature adjustment, comprise tank shell, water inlet pipe and heat exchanger, described water inlet pipe is close on the lower house that is coiled in tank shell, described heat exchanger is fixedly mounted in the upper shell of tank shell, the water inlet of heat exchanger is communicated with water inlet pipe, the delivery port of heat exchanger is communicated with hot water outlet pipe, on described water inlet pipe, be parallel with water inlet pipe branch road, described water inlet pipe branch road is directly communicated with hot water outlet pipe, on water inlet pipe branch road, is provided with normally closed solenoid valve.
Described heat exchanger is plate-fin heat exchanger, and heat exchanger comprises heat exchanger tube and heat exchange fin, and heat exchanger tube bends setting repeatedly, and adjacent tubes gap is even, and described heat exchange fin two ends are close in the gap that is arranged on heat exchanger tube.
Described heat exchange fin is waveform.
Described heat exchange fin is fold-line-shaped.
Described heat exchange fin is equidistant stacked setting.
The cross section of described heat exchanger tube is the flat tube of ellipse or kidney-shaped.
The gas water heater water road system of the utility model unsteady flow temperature adjustment is provided with a water inlet pipe branch road that is directly communicated with hot water outlet pipe from water inlet pipe, this water inlet pipe branch road state in closing all the time when water heater is normally worked, only have user's discharge of working as too low, burner reaches minimum of a value leaving water temperature when still too high, just can open normally closed solenoid valve, controller is controlled by the aperture to magnetic valve, open the path of water inlet pipe branch road, to guarantee normally bathing of user, improved the range of application of water heater, make water heater more be adapted at condition poor, the district work that hydraulic pressure is lower.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, 2, a kind of gas water heater water road system of unsteady flow temperature adjustment, comprise tank shell 1, water inlet pipe 2 and heat exchanger 3, described water inlet pipe 2 is close on the lower house that is coiled in tank shell 1, described heat exchanger 3 is fixedly mounted in the upper shell of tank shell 1, the water inlet of heat exchanger 3 is communicated with water inlet pipe 2, the delivery port of heat exchanger 3 is communicated with hot water outlet pipe 4, on described water inlet pipe 2, be parallel with water inlet pipe branch road 5, described water inlet pipe branch road 5 is directly communicated with hot water outlet pipe 4, is provided with normally closed solenoid valve 6 on water inlet pipe branch road 5.
The utility model can further describe into, described heat exchanger 3 is plate-fin heat exchanger, heat exchanger 3 comprises heat exchanger tube 31 and heat exchange fin 32, heat exchanger tube 31 bends setting repeatedly, adjacent tubes gap is even, adjacent tubes gap is the passage of high-temperature flue gas, described heat exchange fin 32 two ends are close in the gap that is arranged on heat exchanger tube, the shape of the heat exchange fin 32 in the utility model can be illustrated in figure 3 waveform, also can be illustrated in figure 4 fold-line-shaped, or be illustrated in figure 5 equidistant stacked setting, as discussed the heat exchange fin which kind of form is set, can not exceed protection domain of the present utility model.
In the utility model, when stable water pressure water heater is normally worked, normally closed solenoid valve 6 is all the time in closed condition, and water inlet pipe branch road 5 does not have current to pass through; Only have when burner is during in minimum firepower, when water temperature is still overheated, user can select to open low hydraulic pressure pattern, now the controller of water heater just can be controlled the aperture of normally closed solenoid valve 6, after normally closed solenoid valve 6 is opened, part current can flow directly to hot water outlet pipe 4 from water inlet pipe branch road 5, have realized the reduction to water temperature; Because now the firepower of burner is minimum, so even discharge reduces in heat exchanger, can not make heat exchanger cross cause thermal damage yet, can not have influence on the security of water heater, due to the flow of water inlet pipe 2 entrances and for changing, so gas linkage apparatus for gas still can guarantee that burner is in running order, guarantees normally bathing of user.
In the utility model, in order to guarantee the heat exchange efficiency of heat exchanger under normal condition, the cross section of described heat exchanger tube 31 is the flat tube of ellipse or kidney-shaped, can increase to a certain extent heat exchange area like this, guarantees the performance of heat exchanger.
