Description
Technical field
The utility model relates to a kind of gas heater.
Background technology
In the prior art, use gas heater feedwater heating, water to be heated enters from water inlet pipe, becomes hot water in heat exchanger after the heat exchange, flows out rear for the user from outlet pipe.In heat, the water self-temperature that enters from water inlet pipe is just higher, even be higher than the water temperature of user's needs, this moment is again through the heat exchanger heating, then wasted combustion gas, energy-saving effect is undesirable, causes when existing inflow temperature to be higher than user's request, gas heater still starts, and then expends the defectives such as combustion gas.For overcoming these defectives, gas heater is improved.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of gas heater will be provided, and it can be effectively when inflow temperature be higher than user's request, makes the gas heater burning that misfires, and then saves combustion gas.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises water flow switch, impulse controller, magnetic valve, ignition electrode, water inlet pipe, outlet pipe, water inlet pipe, outlet pipe are communicated with heat exchanger respectively, impulse controller and magnetic valve, ignition electrode electrical coupling, it also comprises temperature switch, described temperature switch is installed on the water inlet pipe, and impulse controller and temperature switch electrically connect.
Described temperature switch is for using bimetal leaf as the switch of temperature-sensing element.
Described temperature switch directly contacts with the tube wall of water inlet pipe or the water in the water inlet pipe.
Described impulse controller and water flow switch, temperature switch connect in series form a closed loop.
Described water flow switch is the flow switch that is provided with Hall element.
Described water flow switch is the microswitch in the water vapor linked valve.
The utility model is compared the beneficial effect that produces with background technology:
1, because the utility model adopts temperature switch, temperature switch is installed on the water inlet pipe, whether works the structure that impulse controller and temperature switch electrically connect by the break-make control impuls controller of temperature switch, when inflow temperature was lower than the temperature switch operating temperature, temperature switch was closed; When inflow temperature was higher than the temperature switch operating temperature, temperature switch disconnected, so it can be effectively when inflow temperature be higher than user's request, made gas heater misfire burning and then saving combustion gas.
Description of drawings: Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of temperature switch 2 among Fig. 1.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, present embodiment comprises water flow switch 1, temperature switch 2, impulse controller 3, magnetic valve 4, ignition electrode 5, water inlet pipe 8, outlet pipe 9, water inlet pipe 8, outlet pipe 9 are communicated with heat exchanger 6 respectively, impulse controller 3 and magnetic valve 4, ignition electrode 5 electrical couplings, temperature switch 2 is installed on the water inlet pipe 8, and impulse controller 3 connects with temperature switch 2.
As shown in Figure 2, temperature switch 2 is a kind of with the switch of bimetal leaf 12 as temperature-sensing element, and during normal operation, static contact 10 is in closure state with movable contact spring 11.When temperature was increased to the operating temperature value, bimetal leaf 12 was heated the generation internal stress and movable contact spring 11 is moved rapidly, and static contact 10 is in released state with movable contact spring 11, thereby cut off circuit, played the effect of switch.When temperature drops to below the operating temperature, bimetal leaf 12 does not produce internal stress, and movable contact spring 11 resets rapidly, contacts with static contact 10, connects circuit.
Temperature switch 2 directly contacts with the tube wall of water inlet pipe 8, also can with water inlet pipe 8 in water directly contact.
In the present embodiment, for simplifying circuit, impulse controller 3 forms a closed loop with water flow switch 1, temperature switch 2 connect in series.
Water flow switch 1 can be the flow switch that is provided with Hall element, also can be the microswitch in the water vapor linked valve.The course of work of water flow switch 1 is when water inlet pipe 8 has an amount of water flow, switch closure.
When temperature drops to B, two temperature-sensitive compressing tablet contacts in the temperature switch 2, the closure of realization temperature switch 2, gas water heater ignition work this moment.
When not having current to pass through in the water inlet pipe 8, water flow switch 1 is in off-state, and gas heater is not worked.
When the user opens the outlet valve of gas heater, whether water flow switch 1 is used for detecting has current to pass through (current drive water flow switch 1 closure) in the water inlet pipe 8, whether simultaneous temperature switch 2 detects inflow temperature less than A, if satisfy simultaneously above two conditions, then impulse controller 3 is path with the closed loop that water flow switch 1, temperature switch 2 connect in series form, impulse controller 3 makes ignition electrode 5 igniting, magnetic valve 4 is opened and is made 5 delivery of fuel gas (gas circuit is opened) into Gas Pipe to burner, burner 5 ignition success, the water heater normal operation.
Before water heats in entering gas heater, can tentatively be heated in many ways by these clean energy resourcies such as Teat pump boiler, solar water heater or solar light irradiations, so that temperature is higher after the water temperature preheating, especially in heat, the temperature of water before entering gas heater just surpassed user's demand temperature.
When water inlet pipe 8 interior inflow temperatures during greater than A, temperature switch 2 is in off-state, and gas heater is not worked.Pipeline in the overheated hydrophone of current flows out for the user from outlet pipe 9.Owing to inflow temperature is higher than user's request, need to be rear for the user by behind the mixed water of mixed water valve water temperature suitably being reduced.
After the water heater normal operation, if temperature switch 2 detects suddenly inflow temperature greater than A, temperature switch 2 disconnects, then the loop of water flow switch 1, temperature switch 2, impulse controller 3 formation just disconnects, impulse controller 3 is equivalent to can't detect water-flow signal, then magnetic valve 4 cuts out, and water heater is closed.In this case, if inflow temperature lowers, reach the reset temperature B of temperature switch 2, temperature switch 2 closures so, the loop is connected, and impulse controller 3 detects water-flow signal again, ignition electrode 7 igniting, magnetic valve 4 is opened, and water heater works again.
The utility model can satisfy the user and not start when inflow temperature is higher or close gas heater, start this function of gas heater when inflow temperature is lower, do not expend again too many electric weight, because it closes key control unit is the temperature switch 2 at water inlet pipe place, disconnects and closedly realize the startup of water heater and close by mechanical type temperature switch 2.
Survey inflow temperature if adopt temp probe, because the cost of temp probe is higher, and need uninterruptedly to power to temp probe, get off for a long time to expend more electric weight, must external civil power, and external civil power needs supporting corresponding transformer and relatively complicated circuit control assembly in the gas heater, and whole cost is relatively high.
The utility model uses simple mechanical type temperature switch 2, automatically controls the duty of gas heater by the inflow temperature height, and it is simple in structure, and the complete machine cost is also lower.
