Definitions
- the invention relates to a device for heating heating water and preparing domestic water according to the preamble of the main claim.
- the electromagnetic actuator which responds to the heating requirement is part of a gas fitting containing several valves in a single gas path to the burner, which are controlled by a control device together with the circulation pump and the three-way valve.
- the hydraulic actuator activated by the process water flow only acts on an electrical switch that is located in a signal circuit of the control device for switching the three-way valve and switching on the circulation pump.
- This version is characterized by a high
- the arrangement according to the invention with the features of the main claim has the advantage that simple components can be used for the hydraulic actuator as well as for essential parts of the gas fitting, which are also manufactured in large numbers for pure process water preparation, thereby reducing the cost of manufacture and simplifying storage. Furthermore, the means for regulating the device are also simplified because the control of the gas supply during hot water heating takes place directly through the actuating forces of the hydraulic actuator derived from the hot water flow.
- the arrangement according to the invention is based on the concept of a pure water heater with the greatest possible extent
- a priority circuit for hot water heating can be easily realized if the circuit of the electromagnetic actuator is monitored by a switch which, influenced by the hydraulic actuator, prepares the circuit when hot water is being prepared.
- a cost-effective solution is obtained if the hydraulic actuator activated by the process water flow is part of a functional unit which, in its construction, corresponds to a water shortage protection known from pure process water heaters.
- the switch monitoring the circuit of the electromagnetic actuator can be attached directly to the housing of the low water indicator and can be actuated, for example, by the plunger of the hydraulic actuator which is sealed out of the housing.
- Hot water preparation provided second heat exchanger lies in the course of an inner short-circuit line controlled by the three-way valve.
- the flow cross section of the bypass line in the gas path can be changed by an adjustable throttle device.
- the assembly of the device is made easier if the bypass line is integrated in a gas fitting containing the main gas valve.
- the gas fitting can have a basic housing, as is the case with pure water heaters, and the bypass line can be formed by channels in a housing part placed on the basic housing.
- the combination device has an atmospheric gas burner 10, which is fed via a gas line 11, which leads through a gas fitting 12.
- This contains an ignition safety valve 13, which is opened via a switch button 14 and held in the open position via a magnetic insert 15.
- a pilot gas line 16 branches off to a pilot burner 17 which heats a thermocouple 18 which is in the circuit of the
- thermoelectric ignition fuse 15 the function of which is known and is not to be explained further here.
- the main gas path leads from the ignition safety valve 13 via a lock valve 19 which is actuated by the switch button 14 and closes the main gas path as soon as and as long as the switch button 14 assumes its switch-on position which opens the ignition safety valve 13.
- the main gas path continues from the lock valve 19 via a main gas valve 20 and a gas quantity regulator 21 (not shown in detail) to the injector inputs of burner tubes 22, which are assembled to form a burner grate forming the gas burner.
- a gas quantity regulator 21 not shown in detail
- Ignition energy source is connected, for example to a piezo igniter, which is operated simultaneously with the switch button 14.
- a manually operable extinguishing valve 24 is provided in the ignition gas line 16, via which the ignition gas supply and thereby the heating of the thermocouple 18 is interrupted, after which the ignition valve 13 goes into the closed position.
- a heat exchanger 25 is arranged above the gas burner 10 and is penetrated as a lamella block with a pipe coil through which the heating water flows and symbolized by an elongated pipe section 26. This is on the output side via a flow line 27 with 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, which alternatively connects the suction side of the circulation pump 31 to the heating network connection 30 and to a bypass line 33, which bypasses the
- Heat exchanger 25 leads to the flow line 27.
- the structure and function of the three-way valve 32 are described in more detail below.
- a heat exchanger 34 is installed for the preparation of process water, which flows through the heat exchanger 34 in a coil 35.
- the hot water line 36 passes through a water fitting provided as a whole with the reference number 40, which largely corresponds in structure to a lack of water protection of a pure hot water heater.
- the water fitting 40 has a hydraulic actuator 41, which is influenced by the process water flow, which is coupled to a water quantity regulator 42, and a temperature selector 43 in a bypass channel that bypasses a venturi.
- the operation of such a water fitting is known and is therefore not to be described in more detail here either.
- the three-way valve 32 has a hydraulic actuator 45 with two pressure chambers 46, 47, one of which 46 is constantly pressurized with the pressure in the heating network connection 30.
- the other pressure chamber 47 is connected to an electromagnetically operated switching valve 48, which connects the pressure chamber 47 in the one switching position of the switching valve 48 to the pressure chamber 46 and in the switching position to the pressure side of the circulation pump 31.
- the switching valve 48 is not one Control device shown so influenced that when the heating is requested, the pressure chamber 47 is connected to the pressure side of the circulation pump 31. In this position, the actuator 45 has blocked the bypass line 33 and released the heating network connection 30.
- the main gas valve 20 can be bypassed through a bypass line 50, which is monitored by a gas valve 51, which has an electromagnetic actuator 52.
- the effective flow cross section of the bypass line 50 is adjustable by means of a throttle screw 53.
- the gas valve 51 is controlled with the Umsehaltventil 48 and the circulating pump 31 so that when heating is required, the gas flows to the gas burner 10 even when the main gas valve 20 is closed and the three-way valve 32 blocks the bypass line 33.
- an electrical switch 54 is attached to the water fitting 40, which is actuated by the hydraulic actuator 41.
- the switch 54 is open and closed when the main gas valve 20 is closed.
- the switch 54 influences the switching circuits of the change-over valve 48 and the gas valve 51 in such a way that the bypass line 50 is closed and an inner short-circuit circuit leading via the heat exchanger 34 is produced when hot water is being prepared.
- the switch 54 prevents gas from flowing to the gas burner 10 via the main gas valve 20 and additionally via the bypass line 50.
- the main gas valve 20 can, as shown, have a one-piece closing body with a conical extension 55, through which the valve cross section becomes dependent on the valve lift.
- the closing body of the main gas valve 20 can also be designed in two parts for a gradual opening.
- a two-point control can be provided for the flow temperature of the heating water, so that the gas valve 51 manages with a simple open-close magnet as the drive.
- a small control box is sufficient to control the gas valve 51, the changeover valve 48 and the circulation pump 31. No transformer is required because everything can be controlled on a 230 volt basis.
- a microprocessor can be provided, the low-voltage supply of which takes place via an RC element.
