Description of the drawings
Other advantages are obtained by following description of the drawings.One embodiment of the present of invention is shown in the accompanying drawings.Attached drawing, explanation Book and claim include the feature largely combined.Those skilled in the art also comply with destination individually observe feature and by its It is summarized in other significant combinations.
Attached drawing is shown：
Fig. 1 has the schematic representation of the heater of heater assembly.
Specific implementation mode
Fig. 1 shows the heater 32 with heater assembly 10.In the current situation, heater 32 is configured to continous way and adds Hot device.Heater assembly 10 has the gas burner 12 for heating flowing water as needed.In addition, heater assembly 10 The ignition flame intake line 14 of gas supply with the ignition flame 16 for gas burner 12.Heater assembly 10 wraps Cut-off unit 18 is included, which has at least one shut-off valve 20.End unit 18 to be arranged for according at least the one of water A flow performance parameter is interrupted supplies to the gas of ignition flame intake line 14.
There is gas burner 12 flame region 34, ignition flame 16 to be arranged in inside the flame region.Flame region 34 Include at least one heating flame 36 in the normal operating mode.The setting of ignition flame 16 is used for, and lights heating fire as needed Flame 36.Heater assembly 10 has burner gas intake line 24.Use can be provided by burner gas intake line 24 In the fuel gas of heating flame 36.In the current situation, burner gas intake line 24 leads to flame region 34.In addition, Ignition flame intake line 14 leads to flame region 34.
Heater assembly 10 has gas interface 48.Gas interface 48 is off a part for unit 18.Gas interface 48 It is connect with shut-off valve 20 on fluid technique.In the current situation, gas interface 48 is connect with cup 50, and the cup is by shut-off valve 20 limits.
Heater assembly 10 has water lines 38, can be supplied to flowing water by the water lines and be associated with gas combustion The heat exchanger 40 of burner 12.When for example by user demand water, for example, for example, by by user open corresponding tap Lai Trigger the flowing of water.It can certainly consider, heater assembly 10 is a part for automated system, in the automated system Water demand is automatically controlled.
The cut-off setting of unit 18 is used for, and is interrupted when less than the limiting value of flow performance parameter and is led to ignition flame input pipe The gas on road 14 is supplied.In the current situation, flow performance parameter is flow.In the current situation, limiting value is about 1l/min. But it is also contemplated that can especially adapt to other limiting values of application.Corresponding limiting value especially can with it is exemplary herein The limiting value that refers to is different, at 2 times, 5 times, 10 times, 20 times, 100 times, the multiple between the multiple, bigger or more Small multiple proportion.If flow performance parameter is other parameters, such as flowing velocity different from flow, phase can be considered Answer significant limiting value.
Ending unit 18, there is at least one water input element 22 for water, the state of the water input element to depend on stream It moves characteristic parameter and shut-off valve 20 is coupled on the water input element.In the current situation, shut-off valve 20 is mechanically coupled to On water input element 22.Water input element 22 can be flowed through by water.Water input element 22 is connect with water lines 38.In present case Under, water input element 22 is configured to differential pressure switch.Water input element 22 has diaphragm 42, which is can be based on the dynamic of water Pressure head in other words flowing pressure and deform.In the current situation, diaphragm 42 in the case of water flowing towards far from shut-off valve 20 Direction deforms.Shut-off valve 20 is attached to by connecting element 44 on diaphragm 42.The cut-off of connecting element 44 and shut-off valve 20 Body 46 connects.But it is also contemplated that water input element is for example with the electronic sensor for determining flow parameter.So cut Only valve can be opened and closed for example according to the sensor signal of sensor 20.In addition it is contemplated that water input element has extremely A few flow element rotatably supported, the flow element can be rotated due to the flowing of water.This kind of flow element can To be mechanically coupled on corresponding shut-off valve.In addition it is contemplated that shut-off valve is configured to proportioning valve and/or solenoid valve.
The cut-off setting of unit 18 is used for, and the gas for leading to burner gas intake line 24 is interrupted according to flow performance parameter Supply.In the current situation, shut-off valve 20 in closed state especially in an identical manner according to flow performance parameter interrupt from Gas interface 48 leads to ignition flame intake line 14 and leads to the gas supply of burner gas intake line 24.
Ending unit 18 has another shut-off valve 26, which is used for, according to the igniting of gas burner The existence of flame 16 leads to the gas supply of burner gas intake line 24 to interrupt.As long as ignition flame 16 is not present, Then another shut-off valve 26 is closed.Only when flow performance parameter higher than limiting value and when there are when ignition flame 16, The gas supply for leading to burner gas intake line 24 is just opened.In other cases, lead to feeding pipe of burner road 24 Gas supply is interrupted by the shut-off valve 20 and/or by another shut-off valve 26.
Another shut-off valve 26 is arranged on fluid technique behind shut-off valve 20.The shut-off valve 20 and described another 26 limit of shut-off valve, one Room 30, ignition flame intake line 14 are connect with the room.The room 30 passes through another shut-off valve 26 It is connect with another room 52.Burner gas intake line 24 is connect with another room 52.In the normal operating mode, combustible gas Body is reached by shut-off valve 20 in the room 30 from gas inlet pipe road 48.Fuel gas is defeated from the arrival ignition flame of the room 30 Enter pipeline 14.In addition, fuel gas reaches another room 52 from the room 30 by another shut-off valve 26.Fuel gas Burner gas intake line 24 is reached from another room 52.
Heater assembly 10 has flame identification unit 28, and flame identification unit setting is used for, according to temperature management institute State another shut-off valve 26.In the current situation, the setting of flame identification unit 28 is used for, and is grasped according to the temperature in ignition flame region 56 Indulge another shut-off valve 26.Flame identification unit 28 has hygrosensor 58.Hygrosensor is arranged in ignition flame zone In domain 56.Hygrosensor 58 is connect with thermocouple element 60.Thermocouple element 60 is mechanically coupled to another shut-off valve On 26.If the temperature in ignition flame region 56 is more than temperature extremes, another shut-off valve 26 is opened.It can also examine Consider, an other shut-off valve, especially another shut-off valve 26 are alternatively configured as magnet valve and/or proportioning valve.Especially exist In this case it is also contemplated that corresponding shut-off valve can electronically be manipulated by flame identification unit.
In order to light ignition flame 14, heater assembly 10 has igniting element 54.In the current situation, igniting element 54 It is configured to piezoelectrics.Igniting element 54 is manipulated according to existence of the gas flowing in ignition gas pipeline.For this Purpose, ignition flame intake line 54 can for example have flow measuring probe.This kind of flow measuring probe especially can be touched mechanically Send out the manipulation of igniting element 54.It is also contemplated that the electronic control of igniting element 54.
Implement following methods when heater assembly 10 is run, in the method, according at least one flow performance of water Parameter interrupts the gas supply for leading to ignition flame intake line 14.
