Definitions
- the invention relates to a gas hob with at least one gas burner, a main line for gas supply, a main nozzle on the gas burner and acting on the main nozzle operating device for adjusting the heating power of the gas burner between a minimum power and a rated power.
- Rated power represents the highest power that can be permanently accessed.
- the operating device generally comprises a valve which is arranged in the main gas line and offers at least one passage and one closed position. The passage position can usually be adjusted stepwise or continuously between a minimum passage and a nominal passage.
- a particularly high power output is usually generated at the beginning of a cooking process in order to shorten the waiting time until the occurrence of the success of the cooking.
- the increased power output at the beginning of a cooking process is used, for example, the rapid heating of the still cold cooking vessel and also not yet tempered food. Further examples of this are the heating of a large amount of water or the sharp searing of meat.
- the power is automatically returned to a level selected by the operator.
- the object of the invention is therefore to provide a device which allows a temporally limited operation of the gas stove above the rated power, ie a so-called booster operation.
- the booster operation should not only be possible at the beginning of a cooking process.
- This object is achieved in a gas hob of the type mentioned by a timer, which allows for the duration of a time interval, an increase in the heating power over the rated power addition.
- heating power increased by about 20 to 30% for a period of, for example, 10 to 15 minutes.
- a Limiting the time interval of the power overrun is required for gas stoves, because the rated output of the gas range is selected so that it can be retrieved without damage even in continuous operation. Exceeding the rated output could, for example, cause stainless steel parts in the area of the gas hob to discolour permanently when heated above a threshold temperature of approximately 200 ° C.
- An increase in the heating power of the gas burner can be simple
- a blocking member in the main line can be switched via the timing circuit, which allows an additional, so beyond the maximum power addition reaching gas flow to the gas burner.
- the blocking member optionally has a through or a closed position. In order to avoid the above-mentioned damage due to incorrect operation, the blocking member can be activated exclusively via the timer.
- an additional gas line can be switched via the obturator, which opens into an additional nozzle in the gas burner. The increase of the heating power thus takes place in that the gas flow another access to the gas burner is opened.
- the further gas line may have a larger cross section than the main line and be operated for the duration of the time interval as an alternative to the main line.
- the booster operation is thus carried out exclusively via its own line system with its own nozzle. This has the advantage of being over the dimensioning of its own piping system can be precisely defined to prevent damage due to an unintentional power overrun.
- a separate line for booster operation means a higher technical outlay.
- the additional gas line can be operated for the duration of the time interval in addition to the main line.
- the additional line of the second alternative can therefore be dimensioned smaller than that of the first embodiment, which reduces the technical complexity and the cost of the second embodiment.
- Main nozzle which allows the gas passage for the booster operation, and be arranged upstream of a throttle, which defines the rated power of the gas burner.
- the choice of the throttle depends among other things on the burner type and on the different calorific values of different types of gas. It should therefore be easily replaceable - as well as the main nozzle - or easily adjustable. Their adjustment can be ensured in a simple case, for example by means of a screw.
- the further gas line now forms a bypass around a throttle in the main line.
- the performance of the gas burner in booster mode is thus achieved by the fact that the gas flow passes unhindered around the throttle and thus the throttle is quasi suppressed. Thereby, a further reduction of the technical effort for the booster operation can be achieved, because it can be dispensed with a second line and an additional nozzle in the burner.
- an additional route around the throttle can be provided to the gas flow, so that the passage through the throttle and through the further gas line together result in the gas flow for the booster power.
- the gas flow can be offered an alternative route around the throttle, which alone controls the passage of gas through the throttle Booster power while the throttle is fully disabled. While in the first case a simple shut-off valve is sufficient, which opens the further line only in booster mode and otherwise closes, a two-way valve is required for the second possibility, the gas flow either for normal operation by the throttle or for
- Booster operation passes through the further line. In both cases, it makes sense to combine the throttle and the obturator in a compact component with each other in order to reduce the technical complexity and the space required for it.
- the blocking member may be formed as a solenoid valve.
- the blocking member represents a simple technical construction, but its function reliably fulfilled and can be controlled with little technical effort, for example, via switching currents.
- the gas hob can therefore have a control device with a timer, which switches the obturator in response to an operator signal for the duration of the preset time interval.
- a control device is generally provided in any case, in which the function of a timer can be accommodated easily.
- the operator signal can be generated in the simplest form by a switch in a control panel of the gas hob.
- As feedback for the Switching can be provided an optical and / or acoustic display.
- the control device can additionally switch the obturator in response to device-side generated signals.
- These signals preferably relate to the temperature actually detected in the damage-relevant parts.
- they can be measured directly by temperature sensors. This is certainly the most accurate data collection option, but means a high technical effort and correspondingly high costs.
- the temperature can also be determined indirectly over the time that the relevant gas burner is in operation.
- the control device can make the activation of the booster operation dependent on whether the relevant gas burner is already in operation and thus already has a minimum operating temperature. If this is the case, the control device can shorten the time interval for the booster operation in order to avoid the aforementioned heating of the gas burner beyond a critical temperature and damage as a result.
- FIG. 1 shows a first embodiment of the invention with only one main nozzle on the gas burner
- Figure 2 shows a second embodiment of the invention with two nozzles per gas burner
- Figure 3 shows a third embodiment also with two nozzles per gas burner
- Figure 4 shows a fourth embodiment in which a locking member is formed as a valve block with a number of control lines, not shown.
- Figure 1 shows the schematic structure of a gas range with a gas burner 1, which is supplied via a main gas line 2 with fuel.
- the main gas line 2 leads from a gas source 3, which is shown schematically with an arrow, via a control element 4 to a
- the control element 4 comprises a rotary knob or toggle 6, which serves for manually switching on or off a gas flow through the main gas line 2. It cooperates with a gas tap 7 which is arranged in the main gas line 2 and effects the gas flow through the main gas line 2 according to the adjustment.
- two branches 8 are arranged, between which two gas line sections 9 and 10 are guided in parallel.
- a throttle 11 is arranged, which has a diameter of 1, 25 cm.
- a solenoid valve 12 is arranged, with which the line section 10 can be released or completely closed.
- the branches 8, the throttle 11 and the solenoid valve 12 may be combined in a compact component 13.
- the main gas line 2 opens at its end into the main nozzle 5, which has a diameter of 1, 3 cm.
- the main nozzle 5 thus has a larger diameter than the throttle 1 1.
- This rated power can be, for example, 2.8 KW.
- a so-called booster switch 20 is arranged on a control panel, not shown next to the toggle 6 of the control element 4, a so-called booster switch 20 is arranged. It is connected via an electrical line connection 21 to a control unit 22.
- the control unit 22 is connected to the solenoid valve 12 via a further electrical line connection 23.
- the solenoid valve 12 is thus activated by means of the booster switch 20 exclusively with the interposition of the control unit 22.
- the heating power of the gas burner 1 is controlled by means of the control element 4. At it can between the zero crossing or a minimum power shortly before extinguishing the Gas burner flame and a nominal power of gas flow in the main gas line 2 can be set.
- the gas flow in this case takes the path through the main gas line 2, the line section 9 and the throttle 11 to the main nozzle 5.
- the heating of a cooking vessel on the gas burner 1 may take an undesirably long time.
- the control unit 22 closes the solenoid valve 12 time-dependent and automatically after a predetermined, for example factory set time interval. As a result, operating errors on the part of the operator and damage as a result are virtually eliminated.
- the gas flow within the main line 2 can in turn be influenced by a control element 4.
- the main gas line 2 now has only one branch 7, at which an additional line 30 branches off and leads to an additional nozzle 31.
- the auxiliary nozzle 31 is arranged as the main nozzle 5 within the gas burner 1.
- the gas flow within the additional line 30 can in turn be switched on or off by a solenoid valve 12. It is activated as in the previous embodiment via a booster switch 20, via line connections 21 to a control unit 22nd acts, which forwards a switching control signal via the line connection 23 to the solenoid valve 12.
- the gas stream takes its way from the gas source 3 along the main gas line 2 to the control device 4 over to the main nozzle 5.
- the gas burner 1 is supplied with fuel during an ordinary cooking process.
- the nominal power of the gas burner 1 is determined in contrast to the above-described embodiment of the diameter of the main nozzle 5.
- the solenoid valve 12 Upon actuation of the booster switch 20, the solenoid valve 12 is the
- Figure 3 represents. Again, the same components are provided with the already known reference numerals.
- a main gas line 2 connects a gas source 3 to a main nozzle 5 in a gas burner 1.
- the main nozzle 5 defines the nominal power of the gas range due to its diameter.
- the gas flow within the main gas line 2 is also controllable by a control element 4.
- the booster switch 20 is connected to a control unit 22 via a line connection 21 as described above.
- the control unit 22 via a line 23 now, however, switches a two-way valve 40, which either frees the way through the main gas line 2 to the main nozzle 5 or alternatively cuts off the main nozzle 5 from the gas source 3 and instead the gas flow through an additional line 41 to an additional nozzle 42 in the Gas burner 1 passes.
- the auxiliary nozzle 42 has a larger diameter than the main nozzle 5.
- valve 40 is acted upon with gas even in normal operation of the gas burner 1 of Figure 3. For then it allows the free passage of the gas flow through the main line 2 to the main nozzle 5.
- the operation of the booster switch 20 now causes the main nozzle 5 is separated from the gas supply and a larger gas flow in the booster mode is performed by the additional line 41. Again, therefore, determines the diameter of the main nozzle 5, the normal or rated power of the gas burner 1.
- the higher booster performance is now defined exclusively by the additional nozzle 42. It is maintained in the already explained manner by the control unit only limited in time and switched off after a predetermined time interval.
