    image 1 GAS REGULATING VALVE, COOKING POINT, AND GAS KITCHEN DESCRIPTION
    The present invention refers to a gas regulating valve, a cooking point, and a gas cooker.
    A gas regulating valve for a gas cooking point may comprise a valve body that is housed in a valve housing. To regulate the flow of combustible gas flowing through the gas regulating valve, the valve body is rotatably housed in the valve housing, and can be rotated from one position.
    10 closing to an open position and, beyond the open position, to a low combustion position. The fuel gas flow through the gas regulating valve is adjustable with continuous progression between the open position and the low combustion position. It is desirable that, at least temporarily, greater burner power can be requested.
    15 Patent application DE 10 2010 030 944 A1 describes a process and a gas cooking oven, in which, in addition to a normal gas stream, an additional gas stream is adjustable. Both gas streams are supplied to the same gas burner.
    Against this background, the present invention solves the technical problem of providing an improved gas regulating valve.
    Therefore, a gas regulating valve is proposed for a cooking point, with a valve housing and with a valve body housed in the valve housing, where the valve body is rotatable in a predetermined direction of rotation of a position of closing, in which the gas regulating valve is closed, to an open position, in which the gas regulating valve is open, where the valve body can continue to rotate in the predetermined direction of rotation, beyond the open position, to a low combustion position, where the volumetric flow of the combustible gas with which the gas regulating valve is traversible is adjustable with continuous progression by turning the valve body from the open position to the low combustion position, where the valve body 30 is rotatable against the predetermined direction of rotation of the open position at a
    image2
    booster position, and where the volumetric flow of the combustible gas is greater in the booster position than in the open position.
    The booster position can also be called the maximum combustion position
    or additional combustion. When the valve body can be turned from the open position to the
    The potentiation position, in comparison with the known arrangements, an additional gas stream can be dispensed with, thus ensuring a simple and economical construction of the gas regulating valve.
    According to one embodiment, the volumetric flow of the combustible gas is constant in the potentiation position.
    10 In contrast to the above, the volumetric flow of the combustible gas is adjustable with continuous or gradual progression when the valve body is turned from the open position to the minimum combustion position.
    According to another embodiment, the gas regulating valve has a timer device that is configured to automatically rotate the valve body of the
    15 booster position to the open position after a predetermined time interval has elapsed.
    The predetermined time interval is preferably one minute and, more preferably, 30 seconds. In this way, it is possible to require for a short time a greater burner power, for example, to heat a greater amount
    20 of water
    According to another embodiment, the valve body is pressable into the valve housing to rotate from the open position to the enhancement position.
    The valve body can only be turned from the open position to the enhancement position if it is pressed simultaneously inside the valve housing. Of this
    25 mode, it is safely prevented from turning involuntarily to the empowerment position.
    According to another embodiment, the gas regulating valve has a spring device, where the valve body is pressable into the valve housing against an elastic force of the spring device.
    image3
    Preferably, the spring device is a helical spring, in particular, a compression spring. The spring device is arranged between a shoulder, provided next to the valve body, and the valve housing.
    According to another embodiment, the valve body is housed in the spring device.
    5 In this way, the achievement of a gas regulating valve structure with which space is saved is guaranteed. The spring device is configured to press the valve body out of the valve housing.
    According to another embodiment, the valve housing is fixable by tightening to a main gas line of the cooking point.
    10 In this way, quick and easy assembly of the valve housing next to the main gas line is possible.
    According to another embodiment, the valve body is tubular in shape.
    Specifically, the valve body has a hollow cylinder shaped geometry. A gas passage opening is provided next to the valve body, through which the gas flows
    15 fuel in the open position, in the low combustion position, and in the empowerment position. In the closed position, the gas passage opening is covered by the valve housing.
    Likewise, a cooking point with a gas regulating valve of the exposed type is proposed.
    20 The cooking point is, in particular, a gas cooking point and constituent part of a household appliance.
    A gas cooker with one or more gas regulating valves of the exposed type and / or with a cooking point of the exposed type is also proposed.
    Other possible implementations of the invention also comprise combinations not
    25 explicitly mentioned features or embodiments described above, or below, in relation to the embodiments. Here, the person skilled in the art will also add particular aspects such as improvements or complements to the respective basic form of the gas regulating valve, the cooking point and / or the gas cooker.

    Fig. 6 shows a schematic perspective view of a valve body of the gas regulating valve according to figure 3; Y
    Fig. 7A-7D schematically show different positions of a gas valve actuation button according to figure 3.
    In the figures, the same or equal function elements have been provided with the same reference symbols, as long as nothing else is indicated.
    Figure 1 shows a schematic perspective view of a cooking point, in particular of a gas cooking point 1, and Figure 2 shows a schematic top view of the gas cooking point 1.
    The gas cooking point 1 has a base plate 2 shaped like a bucket, in which the gas burners 3 to 6 are partially or completely housed. A gas regulating valve 7 is assigned to each gas burner 3 to 6. to 10, which are arranged next to a main gas conduit 11, and are in fluid connection with the corresponding gas burners 3 to 6 through supply lines 12 to 15. Also, the gas regulating valves 7 to 10 are configured to continuously regulate a volumetric flow of the combustible gas flowing from the main gas line 11 to the respective gas burner 3 to 6.
    image5
    Figure 3 shows an embodiment of the gas regulating valve 7 in schematic perspective view. The gas regulating valves 8 to 10 are preferably structured analogously to the gas regulating valve 7, so, for simplicity, reference is now made only to the gas regulating valve 7. The gas regulating valve 7 has a valve housing 16, which comprises a gas outlet 17 through which the combustible gas is supplied to the corresponding gas burner 3 to 6 through the corresponding supply conduit 12 to 15. The valve housing 16 also has a housing section 18, which is configured to partially or completely wrap the main gas conduit 11, that is, the valve housing 16 can partially or completely accommodate the main gas conduit 11 in the housing section 18. Next to the housing section 18 there is a gas inlet not shown, through which the combustible gas of the main gas line 11 is supplied to the valve housing 16. The regulating valve of Gas 7 may be immobilized next to the main gas conduit 11 by the housing section 18.
    A thermal element housing 19 is provided next to the valve housing 16, which is connected with a thermal element, associated with the respective gas burner 3 to 6, such that by means of the thermal element it is possible to monitor the flame of the gas burners 3 to 6; that is, if the gas flame goes out, the gas regulating valve 7 blocks the fuel gas stream directed towards the respective gas burner 3 to 6, so that fuel gas no longer flows from the gas regulating valve 7 to the gas burner 3 to 6. A drive shaft 20 protrudes from the upper side of the valve housing 16, next to which, for example, a rotary knob for actuating it can be provided.
    Figures 4 and 5 show in each case a schematic perspective exploded view of the gas regulating valve 7. The thermal element housing 19 is preferably made so that it is removable from the valve housing 16. Laterally next to the housing of valve 16 is provided a drain 21, which is in fluid connection with fuel gas channels provided in the valve housing 16, and which is fluid tightly sealed by a cover 22.
    A valve body 23 is rotatably housed in the valve housing 16, which is tubular in shape and has a projection 24 surrounding it. Between the shoulder 24 and the valve housing 16 a spring device 25 is positioned, which wraps the tubular valve body 23 in sections or in its entirety, and is preferably a compression spring. In addition, the spring device 25 presses the valve body 23 such that it is pressed by the spring device 25 out of the valve housing 16.
    image6
    As shown in Figure 5, next to the valve body 23 there is provided a drive slot 26, in which a corresponding gear section of the drive shaft 20 is engaged in a drive.
    Figure 6 shows the valve body 23 in a schematic perspective view. The valve body 23 has a gas passage opening 27, which overlaps the gas channels provided in the valve housing 16 when the valve body 23 rotates in the valve housing 16.
    Next, the operation mode of the gas regulating valve 7 is described by means of Figures 7A-7D. Figures 7A-7D show in each case a drive button 28, coupled with the drive shaft 20 of the gas regulating valve 7, in different positions. Figure 7A shows the actuation button 28 in a position where the valve body 23 is in a closed position, in which the gas regulating valve 7 is closed and the gas passage opening 27 is fully covered by the valve housing 16. As shown in Figure 7B, the valve body 23 can be rotated in a predetermined direction of rotation 29 of the closed position, in which the gas regulating valve 7 is closed, to a position open, in which the gas regulating valve 7 is open. The default direction of rotation 29 is oriented, by way of example, counterclockwise. An angle of rotation α between the closed position and the open position amounts, for example, to 90 °.
    As shown in Figure 7C, the drive button 28 can continue to rotate in the preferred direction of rotation 29, from the open position to a low combustion position. An angle β between the closed position and the low combustion position amounts, for example, to 210 °. The gas regulating valve 7 is adjustable with continuous progression turning from the open position, shown in figure 7B, to the low combustion position, shown in figure 7C. To move the gas regulating valve 7 from the low combustion position to the closed position, the actuation button 28 is turned back to the closed position, shown in Figure 7A, against the predetermined direction of rotation 29.
    Likewise, as shown in Figure 7D, the valve body 23 can be rotated against the predetermined direction of rotation 29 from the open position to the so-called potentiation position or maximum combustion position. An angle of rotation γ between the open position


    and the potentiation position amounts, for example, to 30 °. In the potentiation position, the volumetric flow of the combustible gas flowing through the gas regulating valve 7 is greater than in the open position and, preferably, is constant and is not adjustable with continuous progression. To rotate the valve body 23 from the open position, shown in 5, Figure 7B, to the enhancement position, shown in Figure 7D, the valve body 23 is pressable into the interior of the valve housing 16 against an elastic force of the spring device 25; that is, the valve body 23 can only be turned to the potentiation position if it is pressed into the valve housing 16 against the spring force of the spring device 25. In the valve housing 16 it can be
    10 provided a booster gas channel, which brings fluid connection to the gas passage opening 27 of the valve body 23 directly with the gas outlet 17.
    The gas regulating valve 7 can also have a timer device 30, which is provided to automatically rotate the valve body 23 from the booster position, shown in Figure 7D, to the open position, shown in Figure 7B, a
    Once a predetermined time interval has elapsed, where the predetermined time interval rises, for example, to 30 seconds.
    A gas cooker 31 (Figure 1) may have one or more gas regulating valves 7 to 10, such as those described above and / or a gas cooking point 1 of the type shown.
    Although the present invention has been described by way of exemplary embodiments, it is variously modifiable.
