Definitions

  • the invention relates to an electric storage heater with a storage core, a charging regulator that controls its charging, a power supply unit that supplies the charging regulator with voltage, and a fan for removing heat from the storage core.
  • a flap device which influences the heat dissipation and which influences the air passage through the storage core can also be provided.
  • the term "fan” also stands for a flap device of the type mentioned.
  • electric storage heaters also have a charge regulator which receives the release signal for the charge releases within low load times either directly or indirectly via a central control device which is jointly assigned to a storage device group. If necessary, the charge controller also receives a control signal via the central control device, which sets the setpoint of the storage core heat content depending on weather and time values as well as preset parameters. The actual value of Speicherkern- heat content 'is detected by a high temperature sensor, which is connected to the Aufladeregier. The output signal of the charge controller switches the power for charging the memory core directly or via an assigned power relay.
  • the heating comfort is largely determined by the discharge of the memory by means of at least one fan.
  • a combined charging and discharging regulator is already known, which can be accommodated with all the essential components in the housing of the electric storage heater.
  • This known controller combination can ensure optimum heating comfort, since a constant exchange of information can take place between the components of the charge and discharge controllers in relation to the state of the storage core and the room air temperature behavior.
  • these known combination regulations have not been able to adequately establish themselves on the market. This was because that combined charge and discharge controllers entailed a relatively high additional price on the storage heater, which could not be achieved on the market.
  • the invention has for its object to provide the ' technical prerequisites for improving the cost / benefit ratio and thus the acceptance of combined charging and discharging control systems in electrical storage units.
  • a discharge controller module can be coupled mechanically and electrically to the charge controller and / or another part of the electric storage heater via at least one detachable coupling device; and that the power supply unit supplying the charge controller is also provided for supplying power to the discharge controller module.
  • electrical signals representative of the setpoint and actual values of the storage core heat content can be transmitted to the discharge regulator module via the releasable coupling device; and that a fan control device can be electrically integrated into the fan control circuit via the releasable coupling device.
  • the invention creates the prerequisite for the fact that the variety of device types that previously conflicted with the introduction of cost-effective combination controllers with charging and discharging functions can be drastically reduced.
  • the basic functions of a charge controller are uniform and essential for practically all conventional electric storage heaters; the same also applies to the necessary measurement and influencing variables.
  • the functions and performance options of the discharge controller are largely determined by customer requirements and operating conditions.
  • the invention is based on the consideration that electric storage heaters can be produced inexpensively by all manufacturers with an individual design and basic equipment that fulfills the minimum functions. Basically, all manufacturers can offer their devices with essentially unchanged design and basic equipment. It is only important that all devices in the basic configuration have a simple interface (connector strip) with a uniform connector connection pattern, so that the controller modules which fulfill the discharge function, which may be customer-specific and production-specific, are connection-compatible with the components of the basic configuration and are simple can be plugged on. Only the power supply unit of the basic configuration is to be designed to be a little more powerful, so that the same power supply unit can also take over the power supply of the discharge regulator module to be plugged on.
  • the customer can therefore buy an electrical storage heater in the basic configuration from any storage device manufacturer, if appropriate according to the device design, and select the heating comfort as desired by suitable selection and, if necessary, retrofitting of a discharge controller.
  • the matching connection pattern between the electrical storage heater from any manufacture and the plug-in discharge controller increases the device series and increases the selection options. capabilities for the consumer, accordingly makes the installation or retrofitting of the advantageous combination control affordable and drastically reduces the assembly work even when replacing • controller components. Special assembly tools or knowledge are not required.
  • the charging regulator is designed as a detachable module, in particular a detachable plug-in module, can be mechanically coupled to the housing of the electric storage heater and via plug connections to the common power supply and at least one residual heat sensor is electrically connectable.
  • the discharge controller contains a microcontroller with a microprocessor memory.
  • a discharge controller is capable of learning. It acts as a room temperature optimizer.
  • the microprocessor receives information about the temperature of the memory core and thus the temperature response and the timing of the charge release. Furthermore, the room temperature and the setpoint of the room temperature are communicated to him via a suitable sensor. These actual and setpoints are continuously stored in the memory and, if necessary, passed on to the charging regulator as a disturbance variable via plug devices. With this disturbance variable, the input signal at the charging regulator can then be compensated for on a room-by-room basis, so that an individual-room temperature optimization is achieved.
  • the continuous detection of the room temperature, the temperature response, the detection of the core temperature, the gradient of the discharge curve, maximum and minimum values and the temperature difference, sudden changes in the room temperature (as a result of room ventilation) etc. enable the associated software of the microcontroller ongoing temperature and heating cost optimization.
  • the design of the discharge and charge regulator as plug-in modules also enables a particularly ergonomic arrangement of the associated setpoint adjuster.
  • the charging regulator is preferably arranged on the housing of the electric storage heater in such a way that a setpoint adjuster attached to the charging regulator is accessible from the outside.
  • an outer wall of the electrical storage heater can be provided with a recess through which a part of the plug-in module with the setpoint adjuster protrudes outwards from the housing, so that its actuator can be easily reached and adjusted by the user.
  • an infrared, radio or frequency-modulated remote control device can also be provided, both for setting the room temperature setpoint and the memory core temperature setpoint.
  • Detachable plug connections are preferably provided between the housing of the electric storage heater and the controller modules in the same or in parallel directions.
  • a common connector strip can be arranged, for example, vertically in the housing of the electric storage heater, and the various plug-in modules are inserted one above the other with a positive and / or non-positive connection into this common connector strip.
  • Push-button systems for example, can serve as mechanical connecting elements.
  • an additional switching function for example the plug-in module that switches the output of additional heating elements, can be coupled mechanically and electrically to a part of the electric storage heater and / or to the discharge controller module via at least one further releasable coupling device.
