Definitions
- the invention relates to a device and a corresponding Process for the controlled reduction of the one Burner nozzle of a gas-operated cooking or baking device via a gas feed gas flow Q.
- Common cooking or baking devices for example gas stoves, Gas hobs, gas hobs or gas ovens, have one or more burners in which the gas is mixed with atmospheric oxygen and burned.
- the gas supply to the burner is via a gas supply line from a gas pipeline network, a gas tank or a gas bottle is supplied with gas.
- a gas pipeline network With a city gas pipeline network the feed pressure is approx. 8 mbar to 20 mbar; however, it is subject to fluctuations and can last up to decrease to 4 mbar. In the case of cooking and The feed pressure is approx. 50 mbar.
- the burners have a burner nozzle that is connected the burner to the gas supply line the relevant, the flow resistance limiting the outflowing gas flow forms and thus the maximum heating power of the Brenners determined.
- the flow resistance in the gas supply line can usually be neglected will.
- the following the prior art uses conventional control valves. By partially closing the valve Throttled gas flow and the desired gas flow rate and thus set the desired heating output.
- the Valves by hand.
- the setting accuracy of the valves is relatively low.
- Such proportional also show Valves also have a hysteresis in the control behavior, so that the Flow rate not only from the position of the valve or the display depends on the associated setting knob, but also in which direction the valve actuated to set the desired flow rate (i.e. opened or closed) and how long the previous adjustment path is.
- the operator only focuses on Part on the scale assigned to the valve and changed the position of the valve until the desired one Heating power, which he based on the size of the flame or Can judge the cooking or baking behavior of the food, is reached.
- the desired one Heating power which he based on the size of the flame or Can judge the cooking or baking behavior of the food.
- the present invention takes this state into account the technology based the task, a device and a method for controlled reduction of a burner nozzle a gas-powered cooking or baking device to create a gas feed line Q, by means of which the gas flow can be reproduced with high accuracy is adjustable. According to other aspects desirable that the method and apparatus technically inexpensive to implement, easy to use, work long-term and reliably.
- the gas supply line in two partial gas lines connected in parallel branched is, the first partial gas line is a throttle element for throttling the partial gas stream flowing through it and the second partial gas line a clock switching element to the clocked Switching on and off of the flowing through Part gas stream includes and the throttle element and Clock switching element with on their gas outlet side the burner nozzle. Furthermore, the exit side the clock switching element with a buffer memory connected. That is by means of a control device Clock switching element with adjustable frequency and / or adjustable on / off cycle ratio can be switched on and off.
- a partial gas stream is the gas stream that the Burner nozzle supplied through the respective partial gas line becomes.
- the total gas flow supplied to the burner nozzle results from the sum of the two Partial gas flows.
- the first partial gas stream essentially has one constant strength and is such by the throttle element throttled that he the small position (minimum position) of the burner.
- the average strength of the second In contrast, partial gas flow is variable and results in permanent open clock switching element the large position (Maximum position) of the burner.
- the clock switching element of the second partial gas line has an open and a closed state so that the second partial gas stream must be switched on or off can.
- the clock switching element permanently open (in the following referred to as the one time) corresponds to that from the first and the total gas flow resulting from the second partial gas flow the maximum position of the burner.
- permanent closed clock switching element in the following as a time-out the total gas flow corresponds to the minimum position of the burner.
- the clocked serves to split into two partial gas flows Switching the second partial gas stream on and off in conjunction with the clock switching element on the output side arranged buffer memory.
- the buffer memory serves to fluctuate the current Gas flow to reduce the average total gas flow. In times of the clock switching element second partial gas stream fed through the buffer storage, while in the beginning, the buffer storage essentially is replenished. Through the stored gas volume of the buffer memory can be switched on intensity fluctuations caused by the clock switching element smooth the second partial gas stream, whereby a more evenly, a defined intermediate position of the Burner corresponding total gas flow can be realized.
- the strength of the second partial gas flow and thus the total gas flow through the ratio of the inputs and Timeout of the clock switching element (“on / off clock ratio") determined, i.e. by the ratio of the time intervals, in which this is in the open or the closed state.
- To reduce the Total gas flow is the clock switching element in certain Time intervals switched on and off. Since that Any on / off clock ratio of the clock switching element is variable, the second partial gas flow can in principle continuously reduce, but one specific on / off clock ratio a defined, at constant inlet pressure essentially reproducible second partial gas flow is assigned.
- the time out and Times of the clock switching element can, for example depending on the respective intermediate position of the Brenner between 0.1 and 5 seconds, preferably between 0.5 and and 3 seconds.
- the clock ratio can theoretically any value between zero (minimum position) and assume infinite (maximum position).
- the switching frequency of the clock switching element below Maintaining the clock ratio can be increased.
- the switching frequency of the clock switching element i.e. the average number of switching cycles per unit of time
- the higher the switching frequency the smaller the buffer memory can also be designed.
- the switching frequency of the clock switching element is advantageously between 0.1 and 100, preferably between 0.5 and 5 on-off cycles per second.
- the buffer memory in series i.e. between the gas outlet side the clock switching element and the burner nozzle, is switched.
- the buffer memory parallel to the burner nozzle connected to the gas output side of the clock switching element is.
- This arrangement has the advantage that the buffer memory in this case only a gas connection bushing must have.
- the volume of the buffer memory essentially depends on the pressure of the gas supply network, the burner size (heating output of the burner) and the realizable switching frequency of the clock switching element.
- the larger the buffer storage the more uniform the gas flow supplied to the burner.
- the higher the switching frequency of the clock switching element the smaller the buffer memory can be.
- the volume of the buffer storage is more than 1 cm 3 , preferably more than 10 cm 3 , particularly preferably more than 25 cm 3 per kW of heating power of the burner nozzle.
- the volume can be limited by the realizable space in the practical embodiments or the relevant safety regulations. According to a further preferred feature, it is proposed that the volume of the buffer store is less than 10000 cm 3 , preferably less than 2500 cm 3 , particularly preferably less than 1000 cm 3 per kW of heating power of the burner nozzle.
- the buffer memory be designed so that its storage volume increased with increasing gas pressure and with decreasing Reduced gas pressure. In this way the storage behavior of the buffer memory and thus the Uniformity of the total gas flow to the respective assigned to the on / off clock ratio of the clock switching element Coordinate the gradation of the total gas flow. It will thus only as much gas is stored as for the respective one Intermediate position of the burner is required.
- the buffer memory can advantageously be input or have a second throttle element on the output side, so that by turning the clock switching element on and off caused pressure fluctuations are intercepted and the second partial gas stream is thus more uniform.
- the flow resistance of the throttle element is dimensioned such that the partial gas flow through the throttle element between 1/4 and 1/25, preferably between 1/5 and 1/20 of the partial gas flow through the clock switching element in the open position.
- control device a sequence of successive switching positions has a sequence of clock ratios of the clock switching element is assigned such that the consequence of the fed into the respective switching position of the burner nozzle Gas flows an ascending or descending Consequence forms.
- the control device can, for example a rotary or step switch, a control panel with buttons, which are assigned to the respective switch positions, or also prefers a "touch control panel", one by mere Touch operated switch. The user in this case does not need to be individual Control of the clock switching element to take care of because Control device the selected switching level independently in predefined in the corresponding on / off clock ratio with a predetermined switching frequency.
- Clock ratio of the clock switching element by means of Control device continuously for example by means of of a potentiometer, is adjustable.
- it can continuously adjustable potentiometers also engage in defined intermediate positions.
- the clock switching element can in principle in any Be operated, for example mechanically, pneumatically or hydraulic. According to a preferred characteristic it can be operated electrically.
- the clock switching element can be in an advantageous embodiment a binary solenoid switching valve or a piezoelectric actuated switching valve with an open and be in a closed position.
- Such solenoid switching valves are known and fulfill those to be placed on them safety requirements.
- the electrical control signal when opening and / or Closing the clock switching element, at least in the area of the switching point, edge-controlled, so that the Switching process does not run abruptly.
- the flow resistance of the throttle element in the factory or by User adjustable is a calibration option for setting and adjusting your throttle resistance to a desired value.
- This can be an advantage if in the area of the minimum position of the burner a high accuracy of the gradations should be achieved.
- the throttle element has a fixed flow resistance having.
- the throttle element can, for example as a capillary, capillary tube, nozzle or tube constriction be realized.
- the invention does not solve the problem in absolute terms, reproducible gas flows and heating outputs to realize but solves the problem a predetermined maximum gas flow in reproducible Way down to smaller values. If the maximum Gas flow changes due to network pressure fluctuations, will also be the reduced, graded gas flows change accordingly. The reproducibility of the However, the setting is retained. With regard on the fact that network pressure fluctuations are only slight Measures affect the heating output, only take place gradually and the resulting changes in heating power also with the conventionally used tap valves to be accepted, the invention represents a significant improvement over the state of the Technology for reproducible, controlled reduction of the Gas flow represents. If necessary, the inventive Device also with a device that Fluctuations in the gas pressure in the gas supply line are compensated or reduced, combined.
- Fig. 1 shows one of a gas supply network, one Gas tank or a gas bottle supplied gas supply line 1 for the controlled supply of gas to a Burner nozzle 3, which is part of a burner 2, e.g. built into a gas stove or gas oven can be.
- a Burner nozzle 3 which is part of a burner 2, e.g. built into a gas stove or gas oven can be.
- Those for gas-powered are not shown Cooking and baking devices usual security elements (Thermocouple and associated solenoid valve), the interrupt the gas flow when the flame goes out.
- the gas feed line 1 branches into two connected in parallel Partial gas lines 4,5, which then become one again burner feed line 10 connected to the burner nozzle 3 unite.
- the line 1 'leads to further, not shown Burners.
- the first partial gas line 4 has a throttle element 6 designed as a capillary with a fixed flow resistance, which serves to reduce the partial gas flow Q 1 of the first partial gas line 4 to a fraction of the maximum gas flow Q max supplied.
- the flow resistance of the capillary 6 can, for example, be designed such that the first partial gas flow Q 1 is essentially 1/6, in a particularly complex embodiment essentially 1/20, of the second partial gas flow Q 2 of the second partial gas line 5.
- the capillary 6 is preceded by a switching element 8 for switching the first partial gas flow Q 1 flowing through the capillary 6 on and off.
- This arrangement has safety-related advantages, since in comparison to an inverted arrangement (switching element 8 connected to the capillary 6), fewer components are under gas pressure in the closed position of the switching element 8.
- the switching element 8 is an electrically operable binary solenoid switching valve. In principle, however, it can be actuated as desired, for example mechanically, pneumatically or hydraulically.
- the second partial gas line 5 has a clock switching element 7 for clocked switching on and off of the second partial gas flow Q 2 flowing through it.
- the clock switching element 7 is also designed as an electrically actuated binary magnetic clock switching valve.
- the output side of the solenoid switching valve 7 is connected via a gas inlet connection bushing 11 to a buffer store 9, which in turn is connected to the burner feed line 10 via a gas outlet connection bushing 12 so that gas flows through the buffer store 9.
- the total gas flow Q fed to the burner nozzle 3 results from the sum of the essentially constant first partial gas flow Q 1 and the variable second partial gas flow Q 2 . If, for example, the solenoid switching valve 8 is open and the solenoid switching valve 7 is closed, the total gas flow Q corresponds to the amount of gas required for the minimum position of the burner 2. If both the solenoid switching valve 8 and the solenoid switching valve 7 are open, the resulting total gas flow Q corresponds to the amount of gas required for the maximum position of the burner 2.
- both valves 7, 8 are opened and closed at a suitable clock rate.
- the solenoid switching valve 8 is closed only for completely switching off the burner 2 and is thus open in all combustion stages between the minimum and maximum positions of the burner 2.
- the magnetic switching valve 7 is alternately opened and closed for the realization of intermediate positions for defined time intervals. The longer the time-out of the magnetic switching valve 7, the smaller the total gas flow Q.
- the buffer store 9 dampens the fluctuation of the second partial gas flow Q 2 and thus the total gas flow Q via its stored gas volume, since it emits gas during times of the magnetic switching valve 7 and on the other hand, in the times of the magnetic switching valve 7 is initially partially refilled.
- FIG. 2 corresponds to that of FIG. 1 with the difference that the buffer store 9 is connected on one side to the output side of the magnetic switching valve 7 via a gas connection bushing 13, which simultaneously enables gas to enter and exit from the buffer store 9, ie is connected in parallel to the burner nozzle 3.
- the section of the second partial gas line 5 located on the output side of the magnetic switching valve 7 has a branching into two partial sections 5a, 5b, of which the first partial section 5a opens into the burner feed line 10 and the second partial section 5b opens into the buffer store 9.
- the second partial gas flow Q 2 fed to the burner feed line 10 is fed both from the gas feed line 1 and from the buffer store 9 in the times of the magnetic clock switching valve 7, and only from the buffer store 9 during times when the magnetic clock switch valve 7 is off.
- FIG. 3 also shows an embodiment with a buffer store 9 connected in parallel to the burner nozzle 3.
- This embodiment provides a switching element 8 ', which can preferably also be an electrically actuated binary magnetic switching valve, which is located in the gas feed line 1 before branching into the two partial gas lines 4,5 is located and thus upstream of both the capillary 6 and the magnetic switching valve 7.
- the switching element 8 ' With the switching element 8 ', both the partial gas flow Q 1 through the capillary 6 and the partial gas flow Q 2 through the magnetic switching valve 7 can be switched on or off at the same time.
- This arrangement of the solenoid valve 8 ' has the application-related advantage that it can be used for safety shutdown of the burner when the flame is extinguished. An additional safety switching valve can be saved in this way.
- a switching position is not shown in FIGS. 1 to 3 having control unit that for a possible simple, clear and safe operation of the Brenners by the user the on / off clock ratio of the solenoid switching valve 7 in the regulation of the total gas flow and thus controls the heating power.
- the on / off clock ratio of the solenoid switching valve 7 in the regulation of the total gas flow and thus controls the heating power.
- the opening or closing the solenoid valve 8 or 8 'at Switching the burner 2 on or off is also preferred controlled by the control unit.
