Definitions

  • the invention relates to a gas valve unit for setting gas volume flows to a two-circuit gas burner of a gas appliance, in particular a gas cooking appliance, the gas valve unit having one gas inlet and two gas outlets.
  • Gas burners are often used in gas cooking appliances, which have two concentrically arranged rings with gas outlet openings.
  • a flame ring can burn on each of the rings with gas outlet openings during operation of the gas hob. If the gas volume flows to the two rings with gas outlet openings can be set separately from one another, these gas burners are referred to as dual-circuit gas burners.
  • dual-circuit gas burners Compared to conventional gas burners with only one flame ring, dual-circuit gas burners generally have a higher maximum combustion output.
  • 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 greatest possible flames. With minimal burning power, only the smaller flame ring burns with the smallest possible flames, while no gas flows out of 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 second partial gas line leading to the larger ring with gas outlet openings.
  • Such gas valve units are also referred to as two-circuit gas valves.
  • Two-circuit gas valves have a single actuating element 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 gas flow to both flame rings immediately opened completely when the actuating element is actuated. Pressing the control element further reduces the output of the larger flame ring until it has completely extinguished. The output of the smaller flame ring is then reduced until it has reached its minimum output.
  • 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 to both rings with gas outlet openings is open.
  • Known gas valve units for dual-circuit gas burners are generally designed as plug valves, in which a valve plug is rotated in a valve housing by means of the actuating element.
  • the exact setting of a desired combustion performance and the reproducibility of such a setting proves to be difficult.
  • the WO 2009/064768 describes a gas stove with removable burners according to the prior art.
  • the present invention is based on the object of providing a generic gas valve unit which is simple in construction and in which the adjustability is improved.
  • the gas volume flow supplied to a first gas outlet can be set in several stages and in that the gas volume flow supplied to a second gas outlet can be set in multiple stages
  • the gas valve unit for adjusting the gas volume flow supplied to the first gas outlet being at least two first on-off valves and one first throttle section with at least two first throttle points which are arranged in series and which comprise an increasing flow cross-section in a gas flow direction in the first throttle section
  • the gas valve unit for adjusting the gas volume flow supplied to the second gas outlet has at least two second open-close valves and a second one Throttle section with at least two second throttling points, which are arranged in series and which comprise an increasing flow cross section in a gas flow direction in the second throttle section
  • at least some of the open-close valves can be switched by means of magnetic force by positioning at least one magnetically active body and at least one first open-close Valve can be switched by means of a force acting mechanically on this first open-close valve, a movement device being provided for
  • the gas valve unit forms several 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 depends on which of the open-close valves are open. This in turn depends on which of the throttle points must be flowed through by the gas on the way from the gas inlet to the gas outlet.
  • the gas valve unit has first open-close valves and first throttle points that are assigned to the first gas outlet, and second open-close valves and second throttle points that are assigned to the second gas outlet.
  • some of the on-off valves can be actuated by means of magnetic force, in particular by moving a permanent magnet.
  • the permanent magnet can be moved relative to the open-close valves and opens the open-close valve that is located directly in the magnetic field of the permanent magnet.
  • at least one 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 also be opened when the permanent magnet is not in its vicinity.
  • Exactly one first open-close valve can preferably be switched by means of a force acting mechanically on this first open-close valve.
  • each of the non-mechanically actuated open-close valves can be switched by means of magnetic force by positioning the magnetically active body.
  • the mechanically switchable on-off valve can also be switched by means of magnetic force.
  • the magnetically active body is particularly advantageously designed as a permanent magnet.
  • Each of the on-off 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 in the closed position by the force of a spring.
  • valve body moves into an open position against the spring force. It is also possible to design the valve body itself permanently magnetic or to connect it permanently to a permanent magnet, while the movable magnetically active body is formed from a non-magnetized ferromagnetic material.
  • a moving device is provided for moving the magnetically active body relative to the on-off valves.
  • the movement device can, for example, be operated by an operator by hand using a rotary knob. It is also possible to couple the movement device to an electrical 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 preferably designed in such a way that, by actuating the movement device, starting from a completely closed gas valve unit, by means of the magnetically active body, the open-close valves assigned to the second gas outlet are actuated first and then, by means of the magnetically active body, the valves assigned to the first gas outlet Open-close valves are operated.
  • the movement device further comprises a mechanical actuation device for the mechanically switchable first open-close valve.
  • the mechanical actuation device With the mechanical actuation device, the mechanically switchable first open-close 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 one second open-close valve is opened by means of magnetic force, the mechanically switchable first open-close valve is opened by means of the mechanical actuation device. Whenever the gas flow to the second gas outlet and thus to the external burner of the dual-circuit gas burner is opened, the mechanical actuation device also opens the gas flow to the first gas outlet and thus to the internal burner.
  • the movement device is designed such that when the magnetically active body is positioned in such a way that it exerts a magnetic force acting in the opening direction on the mechanically switchable first open-close valve, this mechanically switchable first open-close valve also by means of the mechanical actuator is open. In the switch position mentioned, this mechanically switchable first on-off valve is opened both mechanically and by means of magnetic force. This avoids undefined switching states.
  • the movement device is designed such that when the magnetically active body is positioned such that it exerts a magnetic force acting in the opening direction only on at least one non-mechanically switchable first open / close valve, the mechanically switchable first open / close valve is also not opened by means of the mechanical actuation device.
  • the mechanical actuation device In such a switching position, in which the flow cross-section to the first gas outlet is set to a value which is less than the maximum value by means of the magnetic force, the mechanical actuation device has no effect.
  • no open-close valve or exactly one open-close valve or exactly two open-close valves are opened by means of magnetic force.
  • No open-close valve is open when the movement device is in the zero position.
  • the magnetically active body opens exactly one open-close valve when it is located 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 prevents the gas flow from being completely interrupted briefly during the switchover and the flames on the gas burner thereby extinguishing.
  • a movable valve body of the mechanically switchable first open-close valve has a cylindrical base body and a driver.
  • the cylindrical base 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 preferably protrudes from the base body in the circumferential direction.
  • the driver can, for example, be annular and have a larger circumference than the base body.
  • the mechanical actuation device of the movement device has a movable cam which exerts a force on the driver as a function of the switching position of the movement device.
  • the cam can be made so long that it opens the mechanically switchable open-close 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 have a connecting section between two adjacent first throttle points, which connects a first open-close valve to the gas inlet in the open state.
  • the choke points are located one behind the other and are arranged in a row. Depending on which open-close valve is open, the gas flow leads through one, two or more throttling points.
  • the gas valve unit according to the invention comprises a second throttle section, in which the second throttle points are arranged in series and each have a connecting section between two adjacent second throttle points, each of which connects a second open-close valve in the open state to the gas inlet.
  • the throttling points of the first throttling section have an increasing flow cross section — viewed in the gas flow direction in the first throttling 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.
  • the throttle point that follows the open on-off valve in the gas flow direction thus primarily determines the gas volume flow to the gas outlet in question.
  • the throttling points following in the throttle section have a larger flow cross-section and have a comparatively lower throttling effect on the gas volume flow.
  • Fig. 1 shows a two-circuit gas burner 1, as is usually used in gas hobs.
  • 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 set separately.
  • At minimum output of the two-circuit gas burner 1 only 21 flames are present on the inner burner.
  • At maximum output of the dual-circuit gas burner 1 flames are present both on the inner burner 21 and on the outer burner 22.
  • the power of the dual-circuit gas burner 1 can be gradually reduced by first starting with the maximum power at which the outer burner 22 and the inner burner 21 burn at maximum power, the flame size on the outer burner 22 is gradually reduced until the External burner 22 is completely extinguished, and then the flame size on the inner burner 21 is gradually reduced until a minimum flame size is reached.
  • the Figures 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 two-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 inner burner 21 of the two-circuit gas burner 1, while the second gas outlet 12 is provided for connection to the outer burner 22 of the two-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 to it are provided to control the open-close valves 15, 16.
  • All second open-close valves 16 and all first open-close valves 15 each have non-magnetic ferromagnetic valve bodies.
  • the open-close valve 15.3 additionally has a driver 7 connected to the valve body.
  • the first open-close valve 15.3 can be actuated by the cam 6 via this driver 7.
  • the magnetically active body 5, formed by a permanent magnet, can exert an attractive force on the valve body of all the first open-close valves 15, including the open-close valve 15.3, and all the second open-close valves 16, when it is above the corresponding valve body is positioned.
  • the basic structure of the gas valve according to the invention corresponds to the structure of the subjects of the European patent applications filed on July 27, 2009 09290589.2 . 09290590.0 and 09290591.8 and the German patent application filed on May 20, 2010 10290271.5 ,
  • the magnetically active body 5 is located next to the open-close valves 15, 16, so that it does not open any of the open-close valves 15, 16.
  • the cam 6 is located next to the first open-close valve 15.3, so that this open-close valve 15.3 is also not open.
  • the two-circuit gas valve 2 is thus completely closed.
  • the magnetically active body 5 is moved to the right in the drawing. The movement of the cam 6 is always synchronous.
  • the circuit inside the two-circuit gas valve 2 is described below using the schematic Figures 2 to 7 explained in different switching positions.
  • the open-close valve 16 When the open-close valve 16 is open, a second branch of the gas flow leads from the gas inlet 3 via this open second open-close valve 16 and through at least one of the second throttle points 18 to the second gas outlet 12.
  • the first throttle points 17.1, 17.2 and 17.3 have three cross sections that increase in size — viewed in the gas flow direction through the throttle points 17 from right to left.
  • the gas volume flow flowing to the first gas outlet 11 is essentially only defined by the first throttle point 17 located in the gas flow. If, for example, the open-close valve 15.1 is open, the throttle point 17.1 in particular determines the size of the gas volume flow.
  • the throttle point 17.2 determines the gas volume flow; when the open-close valve 15.3 is 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 there is practically no further throttling of the gas volume flow.
  • the circuit and the mode of operation of the second open-close valves 16 in connection with the second throttle points 18 in the branch of the gas volume flow leading to the second gas outlet 12 are analogous.

  • the opened second open-close valve 16.6 enables a maximum gas volume flow via the second throttle point 18.6 to the second gas outlet 12.
  • the magnetically active body 5 moves further to the right in the drawing, 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 the opening of a further first open-close valve 15.2 or 15.3, since these have no driver.
  • This switch position is in Figure 4 shown.
  • the major part 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 added through the open on-off valve 16.5 and the throttle point 18.5 is comparatively negligible.
