Definitions

  • the invention relates to a management device electronics for electric storage water heaters.
  • Thermostatic regulation and tripping in heating resistor supply security of an electric storage water heater is generally provided by an electromechanical thermostat.
  • These thermostats electromechanical devices of known type generally occur in the form of assemblies comprising probes temperature, bimetallic rod, disc or bulb expansion of liquid acting mechanically on electrical power contacts.
  • thermostats as a means thermostatic regulation and tripping in security is little known in this application.
  • the resistance of the water heater is supplied by multi-position contactors presenting generally three operating modes: a automatic operation, in which the resistance of the water heater is supplied by piloting by means of a signal issued by the electric company during the periods corresponding to off-peak hours or the night tariff; a operating mode ensuring that the resistance of the water heater; and a mode of operation in forced march to ensure a permanent supply, for example in case of lack of hot water.
  • contactors are shown under generally modular electrical elements in the general electrical panel of the installation, at a certain distance from the water heater.
  • the document DE 35 25 323 A1 describes a method and a device to capture, regulate and / or control the operation of a hot water accumulator.
  • the device includes means for thermostatic regulation and safe triggering, cathodic protection means by impressed current anode and contactor means supply of the heating resistance of the water heater electric.
  • An object of the invention is to improve the state of the known technique, by simple and economical manufacture, a improved control accuracy by using electronic means, and adaptability to piloting distance, for example by electronic management centralized.
  • the subject of the invention is a management device electronic device intended to ensure the electronic management of a electric storage water heater, comprising combination: electronic means of regulation thermostatic and safety release, means of cathodic protection by impressed current anode intended for provide cathodic protection of the water heater tank, and power contactor means for the supply of a water heater heating resistor electric, characterized in that the supply of the device, cathodic protection means and means forming contactor are mounted on an electronic card main intended to be secured to a water heater electric storage.
  • the invention also relates to a water heater electric storage, with a management device electronics according to the invention.
  • a device comprises a permanent supply 1 powered for example by three wires comprising a phase P, a neutral wire N and a ground, a fuse 5 of cut-out with voluntary manual reset, a contactor 6 regulation, a safety contactor 7, a contactor 8 to three positions for running operation forced, automatic operation during off-peak periods, and stopped for a power off, a circuit 9 detecting the presence of water to avoid dry heating of the tank and ensuring anti-degassing security to avoid release of hydrogen in the tank, a generator 10 of tank protection current, and a flow indicator 11 current indicating sufficient water filling and a electrical protection of the water heater.
  • a secondary card inserted in the DG thermowell of the water heater carries a temperature probe 2, a regulation and safety amplifier 3 and a sensor 4 temperature for safety triggering.
  • the main electronic card contactors allow the DC heating element to be supplied with water heater while the protective current flowing between the insulated anode A and the tank C of the water heater ensures cathodic protection of the tank.
  • the power supply 1 provides in a known manner from a voltage alternative continuous supply of the device according to the invention, to supply on the one hand a thermostat low power TE electronics with two outputs making part of block 3 and receiving the temperature signals in coming from a share of a silicon diode 2 whose temperature variation is known and from sensor to PTC positive temperature variation forming part of block 4; and to simultaneously supply a block 6 forming regulation contactor and a block 7 forming contactor safety as well as a generator 10 of current per through a block 9 for the presence of water and anti-degassing security.
  • TE electronic thermostat example a component sold by the NATIONAL Company SEMICONDUCTOR under Japanese law under the reference LM 56.
  • the flow of cathodic protection current between the anode A and the tank C is attested by the lighting of light emitting diode 11 in series with the generator 10 of current, while the contactor 8 with three positions selects automatic walking, walking forced or shutdown to power off the body of heated.
  • the invention thus makes it possible to group on the same main electronic card associated with a card secondary electronics grouping blocks 2, 3 and 4, all the functions useful for the electronic management of the water heater, and this by means of a mounted card directly on the tank of the water heater.
  • Figure 4 shows an electronic circuit functionally equivalent to the electronic circuit described with reference to Figure 3, the difference consisting of the use of three-phase contactors for regulation heating or the safety triggering of the heating.
  • FIGS. 5 and 6 another mode of embodiment of the invention differs from the embodiment described with reference to Figures 1 to 4 in that electric accumulators are provided in a block 13 for ensure cathodic protection of the tank of the water heater in the event of a power failure.
  • This embodiment of the invention comprises by a additional block 12 providing a flashing display of the light emitting diode 11 to indicate good operation of cathodic protection, a block 13 comprising the two accumulators and the two diodes charge limiting light emitting of these accumulators and a block 14 for limiting the discharge important of the aforementioned accumulators.
  • the battery charge control is ensured by through the charge control block 15.
  • the other elements referenced 1 to 7, 9 and 10 are identical or functionally equivalent to the elements bearing the references 1 to 7, 9 and 10 in FIG. 2.
  • C, R, DZ, D, DEL, TR, IC, VDR are the symbols commonly used in electronics to designate the components respectively corresponding: capacitor, resistance, Zener diode, light emitting diode, transistor, integrated circuit (phototransistor), variable resistance depending on the voltage (varistor).
