Definitions

  • the invention is based on a device for heating Heating water and preparing domestic water after the Genus of the main claim.
  • a device for heating Heating water and preparing domestic water after the Genus of the main claim In known devices of this Genre is the heating demand for heat responsive electromagnetic actuator part of a gas valve containing multiple valves in a single Gas path to the burner, which together with the circulation pump and the Three-way valve are controlled by a control device. That from hydraulic actuator activated in the process water flow only acts on an electrical switch that is in a signal circuit of the control device for switching of the three-way valve and switching on the circulation pump lies.
  • This version is characterized by a high Control quality of the flow temperature of the heating water and the Industrial water, so that for the electrical Control device that also hot water heating controls, and the gas valve a reasonable effort is provided.
  • the arrangement according to the invention with the features of The main claim has the advantage that both for hydraulic actuator as well as for essential parts of the Gas valve simple, in large quantities for pure Components prepared for process water preparation can be used, which reduces the cost of manufacture and warehousing is simplified. Funding for the Regulation of the device simplified because the control of the Gas supply for domestic water heating directly through the actuating forces of the derived from the process water flow hydraulic actuator.
  • the invention Arrangement is based on the concept of a pure one Domestic water heater under as far as possible Retaining the burner, inner body and the fittings for Gas and water by adding simple means for the heating of heating water for two purposes serving, inexpensive combination device.
  • a priority circuit for domestic water heating can be easily realized when the circuit of the electromagnetic actuator from a switch is monitored, which is influenced by the hydraulic actuator in the case of hot water, the circuit is interrupted.
  • the circuit of the electromagnetic actuator monitoring switch can be connected directly to the housing of the Low water protection installed and for example by the sealed plunger from the housing hydraulic actuator to be actuated.
  • a compact one Execution arises if the for the Hot water preparation provided second heat exchanger in the In the course of an inner controlled by the three-way valve Short circuit line is.
  • the Flow cross section of the bypass line in the gas path through a adjustable throttle device is changeable.
  • the assembly of the device is easier if the Bypass line in a contained the main gas valve Gas valve is integrated.
  • the gas valve can be as with basic housing designed for pure water heaters have and the bypass line can through channels in one the basic housing attached housing part be formed.
  • the combination device has an atmospheric gas burner 10 which is fed via a gas line 11 through a Gas valve 12 leads.
  • the parts 13 to 18 form one thermoelectric fuse, the function of which is known and will not be explained further here.
  • the main gas path leads in from the ignition safety valve 13 Lock valve 19, which is actuated by the switch button 14 and the main gas path closes as soon and as long as the switch button 14 its the ignition safety valve 13 opening Occupies the switch-on position.
  • From the lock valve 19 leads Main gas path continues via a main gas valve 20 and an im individual gas flow regulator 21, not shown, to the Injector inputs of burner tubes 22, which to one Gas burner forming burner grate are assembled.
  • a manually operated extinguishing valve 24 in the Ignition gas line 16 is provided, via which the ignition gas supply and thereby heating the thermocouple 18th is interrupted, after which the ignition safety valve 13 in the Closed position goes.
  • a heat exchanger 25 is located above the gas burner 10 arranged as a slat block with one of Heating water flowed through a straight one Pipe section 26 symbolized pipe coil is interspersed. This is on the output side via a flow line 27 a heating network connection 28 and on the input side via a Return line 29 connected to a heating network connection 30.
  • the return line 29 leads via a circulation pump 31 and a three-way valve 32 that the suction side of the circulation pump 31st alternatively with the heating network connection 30 and with a Bypass line 33 connects, bypassing the Heat exchanger 25 leads to the flow line 27. Construction and Function of the three-way valve 32 are explained in more detail below described.
  • a heat exchanger 34 for the Preparation of domestic water installed, the Flows through heat exchanger 34 in a coil 35.
  • the process water pipe 36 goes through one as a whole with the reference number 40 water fitting, which is under construction with a water shortage protection of a pure Water heater largely matches.
  • the water fitting 40 has one of the process water flow influenced hydraulic actuator 41, which with a Water volume controller 42 is coupled, and one Temperature selector 43 in a venturi bypassing Bypass channel.
  • the operation of such a water tap is known and should therefore not be described in more detail here either to be discribed.
  • the three-way valve 32 has a hydraulic actuator 45 with two pressure chambers 46, 47, one of which 46, constantly is pressurized in the heating network connection 30.
  • the another pressure chamber 47 is electromagnetic actuated switching valve 48 connected, which the Pressure chamber 47 in the one switching position of the Changeover valve 48 with the pressure chamber 46 and in the Switch position with the pressure side of the circulation pump 31 connects.
  • the switching valve 48 is not one shown control device influenced so that at Heat requirement of the heating the pressure chamber 47 with the Pressure side of the circulation pump 31 is connected. In this Position, the actuator 45 has blocked the bypass line 33 and the heating network connection 30 released.
  • the main gas valve 20 can be bypassed by a bypass line 50 by a Gas valve 51 is monitored, which one has electromagnetic actuator 52.
  • the effective one Flow cross section of the bypass line 50 is through a Throttle screw 53 adjustable.
  • the gas valve 51 is with the Changeover valve 48 and the circulation pump 31 controlled so that if heating is required, the gas is also closed Main gas valve 20 flows to the gas burner 10 and that The three-way valve 32 blocks the bypass line 33.
  • the water fitting 40 is fitted with an electrical switch 54, which is actuated by the hydraulic actuator 41.
  • the arrangement is such that at Process water flow through the water fitting 40 and open main gas valve 20, the switch 54 is opened and is closed when the main gas valve 20 is closed.
  • the Switch 54 affects the switching circuits of the Switch valve 48 and the gas valve 51 such that at DHW heating closed the bypass line 50 and an inner, leading over the heat exchanger 34 Short circuit is established.
  • the Switch 54 that gas through the main gas valve 20 and additionally to the gas burner 10 via the bypass line 50 can flow.
  • the main gas valve 20 can be used as shown for this purpose a one-piece closing body with a conical approach 55 through which the valve cross section depends on Valve lift will.
  • the Closing body of the main gas valve 20 for a gradual Opening can also be made in two parts.
  • A can be used for the flow temperature of the heating water
  • Two-point control can be provided so that the gas valve 51st with a simple open-close magnet as the drive.
  • the changeover valve 48 and a small switch box is sufficient for the circulation pump 31. It no transformer is needed because everything is based on 230 volts can be controlled.
  • the Low voltage supply takes place via an RC element.
