Definitions
- the invention relates to a protective device for Hot water tank according to the genus of the main claim.
- Protective devices with a so-called external current anode the anode current prevents corrosion of the metallic bare walls of the memory, without the im Anode located in the storage water consumes and must be replaced.
- Protection devices of the generic type have the External power anode and a built-in power supply independent evaluation electronics with information about the operating or maintenance status of the memory delivering display elements is connected, however, to the Control of the storage heater has no influence.
- the evaluation electronics of the external current probe in the Central electronics of the heater is integrated.
- the evaluation electronics and the power supply for the external current anode in the central electronics of the Heater are in this already existing components, such as Transformer, circuit board, fuse, microprocessor, display, Lamps, etc. also for the corrosion protection of the Hot water storage tank used and additional interfaces saved for power supply.
- the cost of the anode current evaluation or control assigned to the hot water tank and read there the evaluation electronics can also do it all in one separate, preferably at or next to the store arranged housing can be accommodated.
- the cost of the central electronics of the heater only by increasing the power supply (transformer) charged.
- the effort in the special housing of the Evaluation electronics can be used by any Reserves in central electronics, e.g. Fuses, Microprocessor, display and lamps.
- a free line connection between the measuring anode and the Evaluation electronics is omitted if the housing of the Evaluation electronics is connected to the measuring anode.
- FIG. 1 shows a hot water tank and a heater with a protective device after the first Embodiment and Figure 2 according to a protective device the second embodiment
- a hot water tank 10 has a metallic inner body 12, which is surrounded by an insulating jacket 14.
- the Inner body 12 is on the inside with an enamel layer a few bare spots covered. To protect these places a so-called external current anode is provided, which in following is described in more detail.
- a heater 16 is located above the hot water tank 10 arranged that as a heat source for hot water heating and serves for the storage water.
- the heater 16 has one Gas burner 18 and a heat exchanger heated by this 20, which lies in the course of an internal water pipe 22, the a return port 24 for a heating network with a Flow connection 26 connects.
- the heat exchanger 20 is alternatively with the heating network via a reversing valve 28 or with a trained as a pipe coil Heat exchanger 30 connected in the hot water tank 10.
- the Heater 16 includes central electronics 32 which a Gas valve 34, a heating pump 36 and the reversing valve 28 in accordance with the thermostats in the heating network and determined a thermostat 38 in the hot water tank 10 Controls heat demand.
- the provided to protect the hot water tank 10 External current anode has a measuring anode as an active element (Electrode) 40, which is isolated at a suitable point on Inner body 12 is attached and in the storage space protrudes.
- the evaluation electronics and the Mains power supply of the external anode are in the Central electronics 32 of the heater 16 integrated which connected the measuring anode 40 via a line 42 is.
- the central electronics 32 is for this purpose with a integrated evaluation electronics 44, a power supply 46 and a display device 48.
- the integrated Evaluation electronics 44 processes the control and Control signals for the heating circuits and also carries out the Evaluation tasks of the external current anode. It is next to a corresponding advertisement also the release of the Gas supply blocked when continued operation Hot water storage tank could damage.
- the protective device according to FIG. 2 differs from that according to Figure 1 in that the external current anode has independent evaluation electronics 50 in a housing 52 is arranged, which is connected to the measuring anode 40.
- a central electronics 54 in the heater 16 has as in the a power supply 46 and a display device 48 which in addition to Power supply and optical monitoring of the heating perform the corresponding tasks of the external current probe.
- An evaluation electronics 56 is in the central electronics 54 for the control of the heating including the implementation which, if applicable, of the evaluation electronics 56 of the External current probe responsible blocking signals.
