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. With minimal power, only the smaller flame ring burns with the flames as small as possible, while no gas escapes from the larger ring with flame outlet openings.
- Gas valve units for supplying two-circuit gas burners have a gas inlet, with which the gas valve unit is connected to a main gas line of the gas cooking appliance.
- a first gas outlet of the gas valve unit 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 second partial gas line.
- Such gas valve units are also referred to as dual-circuit gas valves.
- 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.
- a conventional design of a two-circuit gas valve is, starting from a complete closed dual-circuit gas valve, the gas flow to both flame rings immediately fully opened upon actuation of the actuator. Further actuation of the control element initially reduces the power of the larger flame ring until it is completely extinguished. Subsequently, the power of the smaller flame ring is reduced until it has reached its minimum power.
- either the two-circuit gas valve is completely closed or only the gas flow to the smaller ring with gas outlet openings is opened or the gas flow is opened to both rings with gas outlet openings.
- 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, which is simple and in which the adjustability is improved.
- the gas flow supplied to a first gas outlet is multi-stage adjustable and that the second gas outlet gas flow supplied multistage is adjustable, wherein the gas valve unit for adjusting the first gas outlet gas flow supplied at least two first on-off valves and at least has two first throttle bodies and the gas valve unit for adjusting the gas flow supplied to the second gas outlet at least two second open-close valves and at least two second throttle bodies, and wherein at least some of the open-close valves by means of magnetic force by positioning at least one magnetically active body switchable are and at least a first on-off valve by means of a mechanically acting on this first on-off valve force is switchable.
- the gas valve unit forms a plurality of switching stages with which the gas flow to the first gas outlet and to the second gas outlet can be adjusted.
- the flow cross section in each case depends on which of the open-To-Venti le are open. This in turn depends on which of the throttle points must be traversed by the gas on the way from the gas inlet to the gas outlet.
- the gas valve unit has first open-To-Venti le and first throttle points, which are associated with the first gas outlet, and second on-off valves and second throttle bodies, which are associated with the second gas outlet.
- some of the open-close valves can be actuated by means of magnetic force, in particular by moving a permanent magnet.
- the permanent magnet is movable relative to the open-To-Venti len and opens in each case that on-off valve, which is located directly in the magnetic field of the permanent magnet.
- at least a first open-close valve can be switched by means of a force acting mechanically on this open-close valve. This mechanically switchable on-off valve can thus be opened even if the permanent magnet is not in its vicinity.
- a first open-close valve is switchable by means of a force acting mechanically on this first on-off valve.
- each of the non-mechanically actuatable open-close valves can be switched by means of magnetic force by positioning the magnetically active body.
- exactly one open-close valve is mechanically switchable and the other open-close valves are switchable by means of magnetic force.
- the mechanically switchable open-close valve is additionally switchable by means of magnetic force.
- the magnetically active body is designed as a permanent magnet.
- Each of the open-close valves then has a movable valve body made of ferromagnetic material which is movable by means of the force of the permanent magnet.
- the valve body is biased by the force of a spring in the closed position.
- the valve body moves against the spring force in an open position.
- a moving device is provided for moving the magnetically active body relative to the open-close valves.
- the movement device can for example be operated by an operator by hand by means of a rotary knob. It is also possible to couple the movement device to an electric actuator, for example a stepper motor. With the movement device, the magnetically active body can be moved along the open-close valves on a defined path.
- the movement device is designed such that by actuation of the movement device, starting from a completely closed gas valve unit, by means of the magnetically active body first the second gas outlet associated open-close valves are actuated and then by means of the magnetically active body which the first gas outlet On-off valves are operated.
- the movement device further comprises a mechanical actuation device for the mechanically switchable first open-close valve. With the mechanical actuator, the mechanically switchable first on-off valve can be opened, even if the magnetically active body is not in the vicinity of this first on-off valve.
- the movement device is designed such that when at least a second open-close valve is opened by means of magnetic force, the mechanically switchable first on-off valve is opened by means of the mechanical actuator. Whenever the gas flow to the second gas outlet and thus to the outer burner of the two-circuit gas burner is opened, the mechanical actuator also opens the gas flow to the first gas outlet and thus to the inner burner.
- the moving device is designed such that, when the magnetically active body is positioned to exert an opening force magnetic force on the mechanically switchable first on-off valve, this mechanically switchable first open-close valve also by means of mechanical actuator is open. In the switching position mentioned, this mechanically switchable first open-close valve is open both mechanically and by means of magnetic force. This avoids undefined switching states.
- the moving device is designed such that when the magnetically active body is positioned to exert an opening-direction magnetic force exclusively on at least one non-mechanically switchable first on-off valve, the first on-off valve is mechanically switchable also not opened by means of the mechanical actuator.
- the mechanical actuator In such a switching position, in which is set by means of the magnetic force of the flow cross-section to the first gas outlet to a value which is less than the maximum value, the mechanical actuator has no effect.
- no open-close valve or exactly one open-close valve or exactly two on-off valves are opened by means of magnetic force.
- No on-off valve is open when the mover is in the zero position.
- the magnetically active body opens exactly one open-close valve when it is directly above this open-close valve. In intermediate positions, when the magnetically active body is between two open-close valves, these two open-close valves are open. This avoids that during the switching of the gas flow is briefly completely interrupted and thereby extinguish the flames on the gas burner.
- a movable valve body of the mechanically switchable first open-close valve has a cylindrical base body and a driver.
- the zylinderische body is guided in a cylindrical bore in a housing of the gas valve unit.
- the mechanical actuating device can exert a force on the cylindrical base body via the driver and move it.
- the driver is from the body in the circumferential direction.
- the driver may for example be annular and have a larger circumference than the main body.
- the mechanical actuating device of the movement device has a movable cam, which exerts a force on the carrier in response to the switching position of the movement device.
- the cam can be designed to be so long that it opens the switchable mechanical open-to-valve over several switching positions of the movement device.
- 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 throttle points are located one behind the other and are arranged in series. Depending on which open-close valve is open, the gas flow passes through one, two or more orifices.
- the gas valve unit comprises a second throttle section, in which the second throttle points are arranged in series and each between two adjacent second throttle points have a connecting portion which connects in each case 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 throttle points in the second throttle section - viewed in the gas flow direction in the second throttle section - have an increasing flow cross-section.
- that throttle point which follows the open on-off valve in the gas flow direction determines the gas volume flow to the relevant gas outlet.
- the throttle points following in the throttle section have a larger flow cross-section and have a comparatively smaller throttling effect on the gas volume flow.

- FIG. 2 shows the switching position of the closed two-circuit gas valve
- FIG. 4 shows the switching position of the two-circuit gas valve between a first and a second switching position

- FIG. 8 shows a sectional view of the closed two-circuit gas valve
- Fig. 1 shows a two-circuit gas burner 1, as it is commonly used in gas cooking.
- the dual-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 volume flows emerging 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.
- 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 gradually reduced by, starting from the maximum power at which the outer burner 22 and the inner burner 21 burn with maximum power, first, the flame size at the outer burner 22 is gradually reduced until the Outside burner 22 is completely extinguished, and then the flame size at the inner burner 21 is gradually reduced until a minimum flame size is reached.
- FIGS. 2 to 7 schematically show 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 dual-circuit gas valve 2 has a single gas inlet 3, a first gas outlet 11 and a second gas outlet 12.
- the first gas outlet 11 is provided for connection to the internal burner 21 of the dual-circuit gas burner 1, while the second gas outlet 12 for connection to the external burner 22 of the dual-circuit gas burner 1 is provided.
- the gas flow to the first gas outlet 11 is controlled by first open-close valves 15 (15.1 to 15.3), the gas flow to the second gas outlet 12 by second open-close valves 16 (16.1 to 16.6).
- a magnetically active body 5 and a non-magnetic cam 6 connected thereto are provided. All second on-off valves 16 and all first on-off valves 15 each have non-magnetic ferromagnetic valve bodies.
- the on-off valve 15.3 additionally has a driver 7 connected to the valve body. Via this driver 7, the first open-close valve 15.3 can be actuated by the cam 6.
- the magnetically active body 5 formed by a permanent magnet can exert an attraction force when acting over the corresponding valve body is positioned.
- the basic structure of the gas valve according to the invention in particular the nature of the interaction of the magnetically active body 5 with the associated on-off 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 and the filed on 20.05.2010 German patent application 10290271.5.
- the magnetically active body 5 In the position shown in Fig. 2, the magnetically active body 5 is located next to the open-close valves 15, 16 so that it opens none of the open-close valves 15, 16.
- the cam 6 is located next to the first on-off valve 15.3, so that this open-close valve 15.3 is not open.
- the dual-circuit gas valve 2 is thereby completely closed.
- the magnetically active body 5 Upon actuation of the dual-circuit gas valve 2, the magnetically active body 5 is moved to the right in the drawing. The movement of the cam 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 2 to 7 in different switching positions.
- a first on-off valve 15 When at least a first on-off 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 throttling points 17 to the first gas outlet 11 Opened to open valve 16, a second branch of the gas flow from the gas inlet 3 via this open second open-close valve 16 and at least one of the second throttle points 18 to the second gas outlet 12.
- the first throttle bodies 17.1, 17.2 and 17.3 have three consecutive - viewed in the gas flow direction through the throttle points 17 from right to left - increasing in 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 operation of the second on-off valves 16 in conjunction with the second throttle bodies 18 in the leading to the second gas outlet 12 branch of the gas volume flow is analogous.
- the magnetically active body 6 is in the drawing to the left of the second open-close valves 16.
- the cam 6 is not in engagement with the driver.
- All on-off 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.
- 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 magnetically active body 5 then additionally opens the second on-off valve 16.5.
- the movement of the cam 6 to the right does not lead to an opening of another first on-off valve 15.2 or 15.3, since they have no driver.
- 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
- both 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 11 gas volume 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. 6 shows the next switching position of the gas valve unit in which the magnetically active body 5 is located in the region of the first open-close valve 15.3.
- the magnetically active body 5 exerts on none of the second open-close valves 16 a magnetic force, so that they are closed.
- the magnetically active body 5 now opens the first on-off valve 15.3 by attracting a valve body of the first open-close valve 15.3.
- the cam 6 also exerts a mechanical opening force on the valve body of the first on-off valve 15.3 via the driver 7.
- the gas flow to the first gas outlet 11 as a result of the opened first on-off valve 15.3 is set to a maximum value, while the gas flow to the second gas outlet 12 is interrupted.
- FIG. 7 shows the minimum position of the gas valve unit in which the magnetically active body 5 opens the first on-off 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 movement of the magnetically active body 5 and the cam 6 is always synchronous.
- the gas flow then first increases to the first gas outlet 11 and then the gas flow to the second gas outlet 12. After the gas flow to both gas outlets 11, 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 and the cam 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.
- FIG. 8 shows a sectional illustration of the gas valve unit according to the invention designed as a two-circuit gas valve 2 in the closed state.
- a rotational movement of the actuating shaft 36 is transmitted via a torsionally stiff, but axially compensating coupling element 38 to a movement device 37 for the magnetically active body (see FIG. 9). and transmitted to the cam 6.
- An electrical switch 42 arranged outside the housing 35 detects an axial depression of the actuating shaft 36 and generates a corresponding signal.
- the mechanically and magnetically actuated first on-off valve 15.3 and the second open-close valve 16.5 are visible.
- Both on-off valves 15.3 and 16.5 are in the closed state. Their valve body 39.3 or 40.5 are pressed by means of the force of the springs 41 against a valve seat. Of the Cam 6 is in a position in which it is not in engagement with a driver 7 arranged on the valve body 39.3. The magnetically effective body 5 exerts no magnetic force on any of the valve bodies 39.3, 40.5.
- Figure 9 shows a sectional view of the dual-circuit gas valve in a further switching position.
- the actuating shaft 36 and with it the moving device 37 is rotated to a position in which the cam 6 of the moving device 37 pulls the valve body 39.3 over the driver against the force of the spring 41 down.
- the open-close valve 15.3 is thereby opened.
- the on-off valve 16.5 is the designed as a permanent magnet magnetically active body 5.
- the magnetic force of the magnetically active body 5 pulls the valve body 40.5 against the force of the spring 41 down.
- the open-close valve 16.5 is opened.
