Definitions
- the invention is based on a gas-fired water heater according to the genus of the main claim.
- a safety device for a gas heated Water heater has become known in which a Temperature sensor for recording exhaust gas backlog outside the housing of the flow control or Train interrupter and at the level of one on the back the flow securing opening is arranged.
- This arrangement has the advantage that in normal operation in particular from the flow control housing and thermal radiation acting on the temperature sensor is reduced and, in the event of security, through an opening exhaust gases flowing back into the flow control are detected.
- the opening for the backlog exhaust gases as well as the Holding device for the exhaust gas temperature sensor are in maintenance-friendly way on an exhaust pipe connection for the flow control provided.
- Figure 1 shows a side view of one Flow protection of a gas-heated water heater arranged exhaust pipe connection with a Monitoring device for back-up exhaust gas
- Figure 2 a view of the arrangement in the direction of arrow A in Figure 1
- Figure 3 is a plan view of the arrangement in Direction of arrow B in Figure 1.
- Figure 1 shows a housing 10 of a flow control for a gas-fired water heater.
- an exhaust pipe connection 12 provided the connection for a not shown Exhaust pipe forms.
- At the exhaust pipe connection 12 is one Holding device 14 for an exhaust gas temperature sensor 16 intended.
- the holding device 14 is U-shaped trained bracket, both of which Leg ends are attached to the exhaust pipe connection 12.
- At the Exhaust pipe connection 12 is on the side at the level of Exhaust gas temperature sensor 16 has an opening 18 in which As FIG. 3 shows, an exhaust gas temperature sensor 16 leading guide tube 20 is attached.
- the flow control 10 fulfills the two for a room air operated gas heated water heater known functions - on the one hand, it works through the side-mounted Openings 22 as a train interrupter for the in operation combustion gases rising above and on the other hand in the event of security, the opposite of the flow direction of the Combustion gases accumulate exhaust gases through the the flow guide 10 provided guide vanes 24th and via the guide tube 20 in the installation room of the derived from gas-fired water heaters.
- FIGS 4 and 5 show the normal operation of a gas-fired water heater.
- the one schematically Burner 26 shown generated in a combustion chamber 28 Combustion gases interact with one above the combustion chamber 28 arranged water-carrying Heat exchanger 30 and leave as exhaust gases cooled down the flow safety device 10 and the adjoining one Exhaust pipe the water heater.
- the operation of the Water heater outgoing from the flow control 10 Heat radiation is arranged on the exhaust pipe connection 12
- Exhaust gas temperature sensor 16 is compared to the known Versions in which the exhaust gas temperature sensor is inside the housing of the flow control is arranged, low, especially since the secondary air rising behind the water heater (dashed arrow in Fig. 4) the exhaust gas temperature sensor 16 additionally cools.
- An NTC sensor or a can be used as the exhaust gas temperature sensor 16
- Thermostat sensors can be used.
