Definitions
- the invention relates to a gas valve unit for adjusting gas volume flows to a two-circuit gas burner of a gas appliance, in particular a gas cooking appliance, wherein the gas valve unit has a gas inlet and two gas outlets.
- gas burners are often used, which have two concentrically arranged rings with gas outlet openings. During operation of the gas hob, a flame ring may burn on each of the rings with gas outlets. If the gas volume flows to the two rings with gas outlet openings are adjustable separately from each other, these gas burners are referred to as two-circuit gas burner.
- dual-circuit gas burners typically have a larger maximum burn rate.
- dual-circuit gas burners have a particularly large spread between minimum burning power and maximum burning power. At maximum burning power, both flame rings burn with the largest possible flames.
- Gas valves for supplying two-circuit gas valves have a gas inlet, with which the gas valve is connected to a main gas line of the gas cooking appliance.
- a first gas outlet of the gas valve opens into a first partial gas line leading to the smaller ring with gas outlet openings.
- a second gas outlet is connected to a leading to the larger ring with gas outlet openings partial gas line.
- Two-circuit gas valves have a single actuator, with which both the gas flow for supplying the first flame ring and the gas flow for supplying the second flame ring can be adjusted.
- the switching position for the maximum power of both flame rings is immediately followed by the completely closed position of the two-circuit gas valve. Further actuation of the control element initially reduces the power of the larger flame ring until it is completely extinguished. Subsequently, the performance of the reduced smaller flame ring until it has reached its minimum power.
- either the two-circuit gas valve is completely closed or open only the gas flow to the smaller ring with gas outlet openings or the gas flow to both rings with gas outlet openings open. However, it is not intended to close the gas flow to the smaller ring with gas outlet openings, while the gas flow is opened to the larger ring with gas outlet openings.
- Known gas valve units for two-circuit gas burners are generally designed as plug valves, in which by means of the actuating element, a valve plug is rotated in a valve housing.
- a valve plug is rotated in a valve housing.
- the present invention is based on the object to provide a generic gas valve unit available, in which the adjustability is improved.
- the gas flow rate is at least one of the gas outputs adjustable in several stages, is interrupted in a zero position of the gas valve unit, the gas volume flow to both gas outputs and is set to a maximum value in a switching position adjacent to the zero position of the multi-stage adjustable gas volume flow.
- the gas volume flow can thus be set exactly and reproducibly in several stages.
- the switching stage in which the gas volume flow is maximum, adjacent directly to the zero position of the gas valve unit.
- the gas valve unit is opened, the gas volume flow is thereby immediately set to a maximum value. This ensures that the gas-conducting components behind the gas valve unit quickly fill with gas.
- ignition of the gas burner takes place particularly reliably at maximum gas volume flow.
- the gas valve unit is thus immediately after opening in an optimal position for igniting the gas burner.
- the multi-stage adjustable gas volume flow is set to a maximum value and the gas volume flow leading to the other gas outlet is also open. After this Opening the gas valve unit is thus immediately open the gas flow to both gas outlets.
- the gas volume flows to both gas outputs can be set in multiple stages, wherein in a switching position adjacent to the zero position both gas flow rates are set to a maximum value.
- all gas-carrying components behind the gas valve unit are filled very quickly with gas. Ignition of the gas burner takes place in the switching position adjacent to the zero position with maximum gas discharge from all gas outlet openings.
- the gas valve unit has at least two open-close valves and at least two first throttle points, preferably at least three first open-close valves and at least three first throttle positions, for setting the gas volume flow supplied to a first gas outlet.
- the number of open-close valves and the number of throttle points are decisive for the number of available switching stages. The more switching stages are available, the finer the burning power of the gas burner associated gas valve can be set.
- Analogous advantages arise when the gas valve unit for adjusting the gas flow supplied to a second gas outlet at least two second open-close valves and at least two second throttle points, preferably at least four second open-close valves and at least four second throttle points.
- At least one magnetically active body is provided, which is movable relative to the open-close valves.
- a magnetically active body may be a permanent magnet capable of attracting a ferromagnetic valve body of the on-off valve.
- the magnetically active body may be a non-permanently magnetized ferromagnetic body when a valve body of the open-close valve is formed by a permanent magnet or connected to a permanent magnet.
- the on-off valves are opened or closed by moving the magnetically-active body relative to the open-close valves. Only if the magnetically active body is in the immediate vicinity of the open-close valve, A magnetic force acts between the magnetically active body and the open-close valve, opening the open-close valve.
- An advantageous embodiment of the invention provides that at least two magnetically active bodies are provided for controlling the open-close valves, wherein a first magnetically active body is formed by a ferromagnetic body and the second magnetically active body is formed by a permanent magnet.
- first magnetically active body and the second magnetically active body are coupled to each other so that they are movable in synchronism with the open-close valves.
- the coupling is preferably carried out so that the two magnetically active body are forced to always synchronously with each other.
- At least one first on-off valve has a permanent magnet, such that this first on-off valve is controllable in dependence on the position of the first magnetically active body formed by a ferromagnetic body.
- the other open-close valves which have no permanent magnet, however, can not be controlled by the first magnetically active body having a ferromagnetic body.
- the first magnetically active body formed by a ferromagnetic body is designed such that it causes in at least three switching positions of the gas valve unit opening of a permanent magnet having on-off valve.
- the on-off valve having a permanent magnet is thus open in several switching positions of the gas valve unit in contrast to the other open-close valves.
- An immediate complete opening of the gas valve unit is achieved in that in a switching position adjacent to the zero position of the first magnetically active body formed by a ferromagnetic body opens the first permanent-magnet having a first on-off valve and the second magnetically active body formed by a permanent magnet a second Open-close valve opens. In each switching position in which the second magnetically active body formed by a permanent magnet opens at least a second open-close valve, the first magnetically active body formed by a ferromagnetic body opens the first open-close valve having a permanent magnet. This ensures that in a dual-circuit gas burner burns at no time only the outer flame ring, while the inner flame ring is not supplied with gas. Instead, the inner ring of flames always burns with the outer ring of flames.
- the first magnetic body In at least one switching position in which the second magnetically active body formed by a permanent magnet opens at least a first open-close valve, the first magnetic body does not open any of the open-close valves. In such a switching position, none of the second open-close valves is open. The first magnetically active body has no function in these switching positions.
- this second magnetically active body opens, either no on-off valve or exactly one on-off valve or exactly two open-close valves.
- No on-off valve opens the second magnetically active body in the zero position of the gas valve unit.
- Exactly one open-close valve opens the second magnetically active body when it is directly over the open-close valve.
- Exactly two open-close valves open the second magnetic active body in intermediate positions between two on-off valves. However, it is ensured that during the switching between two switching positions of the gas valve unit at any time all open-close valves are closed and thereby extinguish the flames on the gas burner.
- the gas valve unit comprises a first throttle section, in which the first throttle points are arranged in series and each between two adjacent first throttle points have a connecting portion, which connects a first open-close valve in the open state with the gas inlet.
- the gas valve unit comprises a second throttle section, in which the second throttle points are arranged in series and each between two adjacent throttle points has a connecting portion which connects a second open-close valve in the open state with the gas inlet.
- the throttle points of the first throttle section have - viewed in the gas flow direction in the first throttle section - an increasing flow cross-section.
- the throttling points of the second throttle section - viewed in the gas flow direction of the second throttle section - also have an increasing flow cross-section.

- Fig. 1 shows a two-circuit gas burner 1, as it is commonly used in gas cooking.
- the two-circuit gas burner 1 comprises an inner burner 21 with first gas outlet openings 31, and an outer burner 22 with second gas outlet openings 32.
- the gas flows flowing through the first gas outlet openings 31 and the second gas outlet openings 32 and thus the Flame sizes of a first flame ring on the inner burner 21 and a second flame ring on the outer burner 22 can be adjusted separately from each other.
- At minimum power of the two-circuit gas burner 1 21 flames are available only on the inner burner.
- both the inner burner 21 and the outer burner 22 flames are available.
- the power of the dual-circuit gas burner 1 can be reduced in stages by first reducing the flame size at the outer burner 22, starting from the maximum power, until no flame burns on the outer burner 22, and then the flame size at the inner burner 21 gradually reduced.
- FIG. 2 shows a gas valve unit according to the invention designed as a two-circuit gas valve 2 for supplying such a two-circuit gas burner 1.
- the two-circuit gas valve 2 has a single gas inlet 3, which adjoins a clamping plate 4 for fastening the two-circuit gas valve 2 in the figure a first gas outlet 1 1 and a second gas outlet 12.
- the first gas outlet 1 1 is provided for connection to the inner burner 21 of the dual-circuit gas burner 1, while the second gas outlet 12 for connection to the outer burner 22 of the dual-circuit gas burner. 1 is provided.
- the gas flow to the first gas outlet 1 1 is controlled by first on-off valves 15, the gas flow to the second gas outlet 12 by second open-close valves 16.
- For controlling the open-close valves 15, 16 are two magnetically active body. 5 , 6 provided.
- the second magnetically active body 6 is formed by a permanent magnet, which can be moved about an axis 8, starting from the illustrated zero position in the counterclockwise direction.
- the first magnetically active body 5 is connected to the second magnetically active body 6 in such a way that it is moved together with the second magnetically active body 6 about the axis 8.
- the first magnetically active body 5 is made of a ferromagnetic material and is therefore not a permanent magnet.
- the characteristic feature of a ferromagnetic material is that it is not magnetic itself, but attracted by a magnet.
- the first magnetically active body 5 is formed by a C-shaped steel sheet and is shown hatched in Fig. 2 transparent.
- the on-off valve 15.3 has a permanent-magnetic valve body, or a valve body connected to a permanent magnet 13.
- the permanent magnet 13 On the valve body of all the first on-off valves 15, including the open-close valve 15.3, the permanent magnet 13 is poled accordingly, and all open-close valves 16, the second magnetically active body 6 formed by a permanent magnet exert an attractive force when positioned over the corresponding valve body.
- the first magnetically active body 5 can exert an attractive force only on the valve body of the open-close valve 15.3, which is designed as a permanent magnet 13 or is coupled to such.
- the basic structure of the gas valve according to the invention in particular the nature of the interaction of the second magnetically active body 6 with the associated open-close valves 15 and 16 and the gas flow in the interior of the gas valve, corresponds to the structure of the objects of the filed on 27.07.2009 European Patent Applications 09290589.2, 09290590.0 and 09290591 .8.
- the second magnetically active body 6 is adjacent to the open-close valves 15, 16 so that it opens none of the open-close valves 15, 16.
- the first magnetically active body 5 is located next to the first open-close valve 15.3, so that this on-off valve 15.3 is not open.
- the dual-circuit gas valve 2 is thereby completely closed.
- the magnetically active bodies 5, 6 are moved counterclockwise about the axis 8. The movement of the magnetic active body 5, 6 is always synchronous.
- the circuit in the interior of the two-circuit gas valve 2 will be explained below with reference to the schematic figures 3 to 1 1 in various switching positions.
- the first magnetically active body 5, the second magnetically active body 6, the first open-close valves 15 (15.1, 15.2, 15.3), the second open-close valves 16 can be seen in each case (16.1 to 16.6), first throttle bodies 17 (17.1, 17.2, 17.3) and second throttle bodies 18 (18.1 to 18.6).
- first open-close valve 15 When at least a first open-close valve 15 is opened, a first branch of the gas flow leads from the gas inlet 3 via this opened first on-off valve 15 and through at least one of the throttle points 17 to the first gas outlet 11.
- a second branch of the gas flow leads from the gas inlet 3 via this opened second on-off valve 16 and through at least one of the second throttling locations 18 to the second gas outlet 12 17.1, 17.2 and 17.3 have three successive - viewed in the gas flow direction through the throttle points 17 from right to left - increasing cross-sections.
- the gas volume flow flowing to the first gas outlet 11 is decisively defined only by the first throttle point 17 located in the gas flow. If, for example, the open-close valve 15.1 is opened, in particular the throttle point 17.1 determines the size of the gas volume flow.
- the throttle point 17.2 determines the gas volume flow, with the open-close valve 15.3 open, the gas volume flow through the throttle point 17.3 is determined.
- the last of the throttling points 17.3 can have such a large flow cross section that virtually no throttling of the gas volume flow takes place.
- the circuit and the mode of operation of the second open-close valves 16 in conjunction with the second throttling points 18, in the branch of the gas volume flow leading to the second gas outlet 12, are analogous.
- this switching position is the first magnetically active body 5 in the drawing left of the first open-close valve 15.3 and the second magnetically active body 6 in the drawing to the left of the second open-close valves 16.
- This position of the magnetically active body 5, 6 corresponds to the switching position shown in Fig. 2.
- all open-close valves 15, 16 are closed by spring force.
- the gas present at the gas inlet 3 can flow neither to the first gas outlet 11 nor to the second gas outlet 12.
- the first magnetically active body 5 formed of ferromagnetic material opens the first open-Zu equipped with a permanent magnet 13 Valve 15.3 and the as Permanent magnet executed second magnetically active body 6 opens the second on-off valve 16.6.
- This switching position is shown in FIG.
- the open first open-close valve 15.3 allows a maximum gas volume flow via the first throttle point 17.3 to the first gas outlet 1 1.
- the opened second open-close valve 16.6 allows a maximum gas volume flow via the second throttle point 18.6 to the second gas outlet 12.
- the second magnetically active body 6 then additionally opens the second on-off valve 16.5.
- the movement of the first magnetically active body 5 to the right does not lead to an opening of another first on-off valve 15.2 or 15.3, since they have no permanent magnet.
- This switching position is shown in FIG. In this case, the majority of the gas flow reaching the second gas outlet 12 flows through the open on-off valve 16.6 and the throttle point 18.6.
- the gas flow through the open on-off valve 16.5 and the throttle restriction 18.5 is comparatively negligible.
- the reaching in this switching position to the second gas outlet 12 gas flow is virtually identical to the gas flow in the switching position shown in FIG. 4th
- This switching position is shown in FIG.
- the open-close valves 16.6 and 16.5 are opened, as this is a continuous Gas flow ensures and prevents unwanted interruption of the gas flow and thus extinction of the gas flame during the switching process.
- the open-close valves 15.3 and 16.1 are opened.
- the leading to the first gas outlet 1 1 gas flow is maximum.
- the gas volume flow leading to the second gas outlet 12 is minimal since it flows through all the second throttle points 18.1 to 18.6 and is thus throttled to a maximum, in particular through the throttle point 18.1 with the smallest flow cross section.
- FIG. 8 shows the next switching position of the gas valve unit in which the second magnetically active body 6 is located in the region of the first open-close valve 15.3.
- the second magnetically active body 6 exerts on none of the second open-close valves 16 a magnetic force, so that they are closed.
- the second magnetically active body 6 now opens the first open-close valve 15.3 in that the second magnetically active body 6 formed by a permanent magnet attracts the permanent magnet 13.
- the permanent magnet 13 is for this purpose poled so that it is attracted to the second magnetically active body 6 and not repelled.
- the gas flow to the first gas outlet 1 1 as a result of the opened first open-close valve 15.3 is set to a maximum value, while the gas flow to the second gas outlet 12 is closed.
- the two magnetically active body 5, 6 are moved further to the right, close and open successively the first open-close valves 15. This happens exclusively by means of the magnetic force of the second magnetically active body 6.
- the first magnetically active body 5 has These switching positions then no switching function.
- the first open-close valve 15. 2 initially opens in addition while the first open-close valve 15. 3 remains open.
- the gas volume flow to the first gas outlet 11 is reduced after the first open-close valve 15.3 is closed and only the first open-close valve 15.2 is opened by the second magnetically active body 6.
- FIG. 11 shows the minimum position of the gas valve unit in which the second magnetically active body 6 opens the first open-close valve 15.1 and all other open-close valves 16, 15.2 and 15.3 are closed.
- the gas flow to the first gas outlet 1 1 flows through all the first throttle points 17 and is thereby throttled maximum.
- the two magnetically active body 5, 6 Upon actuation of the dual-circuit gas valve 2 in the reverse direction, the two magnetically active body 5, 6 are moved back. Again, the movement of the two magnetically active body 5, 6 is always synchronous. In this case, first the gas flow to the first gas outlet 1 1 and then the gas flow to the second gas outlet 12 increases. After the gas flow to both gas outlets 1 1, 12 has reached its maximum value, the two-circuit gas valve is completely closed in the subsequent switching position ,
- An actuation of the dual-circuit gas valve 2 by means of a suitable movement device can for example comprise a manually operable rotary knob. Rotation of the rotary knob then displaces the magnetically active body 5, 6 relative to the open-close valves 15, 16 in the manner described above.
- a suitable actuator such as an electric stepper motor or a combination of electric motor and gearbox.
- This actuator can then be controlled by means of a suitable electronic control.
- the electronic controller then actuates the actuator automatically or in accordance with the output of an electronic user interface connected to the controller, which may be formed, for example, by touch sensors, sliders, or removable magnetic buttons.
