Description

The present invention refers to an arrangement of gas burners, a cooking point, and a kitchen.

A cooking point can have several gas burners, with its own gas regulating valve assigned to each gas burner. To heat a large container of cooking product, it can be placed at the same time, for example, on two

or more gas burners. In order to heat the cooking product container, the power of each gas burner is adjusted with the gas regulating valve assigned to it.

Against this background, the present invention solves the technical problem of providing an improved gas burner arrangement for a cooking point.

Therefore, a gas burner arrangement is proposed for a cooking point, which comprises at least two gas burners and a common gas regulating valve

 to regulate a volumetric flow of gas to at least two gas burners.

As several gas burners can be activated simultaneously with a common gas regulating valve, in the case of large cooking product containers, the cooking product container can be placed at the same time on the gas burners associated with a gas regulating valve common. The heat supply to the product container of

 cooking can thus be adjusted using a single gas regulating valve. Likewise, in this way a simple regulation of several gas burners is simultaneously possible. Since a proprietary gas regulating valve is not necessary for each gas burner, it is possible to save components, which reduces the costs for manufacturing the gas burner arrangement.

 According to one embodiment, the gas burner arrangement also has at least two gas shut-off valves. A gas shut-off valve is assigned to each of the at least two gas burners.

With a gas shut-off valve, the supply of combustible gas to a gas burner can be unlocked or interrupted, while, in comparison with this, with a gas regulating valve the volumetric flow of combustible gas to the gas can be regulated.

gas burner. By means of the gas shut-off valve, gas burners that are not covered by a cooking product container are disconnectable. In this way, a gas leakage from the gas burners that are not necessary is safely avoided, so that no combustible gas is burned in the gas burners that are not

 They need, saving energy.

According to another embodiment, each gas shut-off valve has an actuation element that is movable from an open position to a closed position to alternatively open or close the respective gas shut-off valve. The drive element is prestressed in the direction of the closing position by means of a device

 spring

The spring device is a cylindrical or helical spring, and is preferably arranged in a valve housing of the gas shut-off valve. Preferably, the spring device is positioned in a housing recess of the actuating element, at least in sections, and is provided between the housing of

 valve and drive element. By means of the spring device, the actuating element is automatically movable from the open position to the closed position.

According to another embodiment, the gas burner arrangement has a damping element that dampens a movement of the drive element to the

 move from the open position to the closed position.

The damping element may be a delay element. By means of the damping element, a uniform and abrupt movement of the drive element is guaranteed when it moves from the open position to the closed position. Also, the damping element is configured to retard movement of the damping element.

 actuation of the open position to the closed position; that is, also if the drive element is no longer being pressed by a cooking product container to the open position, the drive element first remains in the open position to automatically move to the closed position after a predetermined time space, for example, after a few seconds.

 This prevents the burner flame from going out if a container of cooking product is removed for a short time.

According to another embodiment, the drive element is in the form of a bar.

Preferably, the drive element has a circular cross-section, and protrudes perpendicularly from a cooking field plate of the cooking point.

According to another embodiment, a central axis of the drive element is arranged in parallel to a respective central axis of the gas burners.

Preferably, the central shafts are positioned perpendicular to the cooking field plate of the cooking point. The central axis of each drive element and the central axis of each gas burner are positioned at a predetermined distance from each other.

 According to another embodiment, the drive element can be loaded with a cooking product container to move from the closed position to the open position.

When loading, the weight of the cooking product container presses the actuator from the closed position to the open position against the spring force of the

 spring device; that is, if a container of cooking product is positioned on the actuating element, the gas shut-off valve is in its open position.

According to another embodiment, when the cooking product container is removed from the drive element, the drive element automatically moves from the open position to the closed position by means of the spring device.

 Thus, when the cooking product container is removed or if, in a gas burner of the gas burner arrangement, the cooking product container is not positioned on the corresponding gas burner, the gas supply is stopped . By means of the damping device, the gas supply is prevented from being interrupted immediately when the cooking product container is removed from the gas burner

 for a short time. Preferably, the damping device is configured to, in case of removing the cooking product container, keep the drive element in the open position for a predetermined time, for example, for a few seconds.

According to another embodiment, a pot holder is associated with each gas burner. The pot holder has the drive element.

The pot holder is configured so that a container of cooking product is placed on it.

According to another embodiment, the drive element and at least two spacers of the pot holder are arranged annularly distributed around the respective gas burner.

Preferably, the front surfaces of the spacers and a front surface of the actuator form a support surface of the pot holder. The spacers preferably protrude from the cooking field plate of the cooking field in such a way that their front surfaces are at the same height as the front surface 10 of the actuator in the open position of the gas shut-off valve. Preferably, the drive element and the at least two spacers are arranged evenly distributed around the respective gas burner. The pot holder can have more than two spacers. As an example, the pot holder can have three or four spacers and the actuator. From

In this way, it is safely avoided that the cooking product container overturns.

According to another embodiment, the spacers are shaped like a bar.

Preferably, the spacers have a circular cross-section, and protrude perpendicularly from a cooking field plate of the cooking point.

According to another embodiment, the gas burner arrangement has a branching gas supply conduit 20, which connects the gas regulating valve with the at least two gas burners.

In this way, a simple and economical structure of the gas burner arrangement is possible.

Likewise, a cooking point with an arrangement of gas burners of the exposed type is proposed.

The cooking point is a gas cooking point, in particular part of a household appliance.

According to one embodiment, the cooking point has several arrangements of gas burners.

As an example, the cooking point may have three gas burner arrangements, a gas regulating valve being assigned to each gas burner arrangement here.

Likewise, a kitchen with an arrangement of gas burners of the exposed type and / or with a cooking point of the exposed type is proposed.

The kitchen is a gas cooker. The kitchen, cooking point and / or gas burner arrangement are configured for domestic use.

Other possible implementations of the invention also comprise combinations not explicitly mentioned of 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 invention.

Other configurations and advantageous aspects of the invention are subject to the secondary claims, as well as the embodiments of the invention.

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 top view of a cooker 1, which comprises a cooking point 2. The cooker 1 is a domestic appliance, namely, a gas cooker. The cooking point 2 has at least one arrangement of gas burners 3-5. As an example, cooking point 2, as shown in Figures 1 and 2, has three

 gas burner arrangements 3-5, although the amount of gas burner arrangements 3-5 can be any.

Each gas burner arrangement 3-5 has a gas regulating valve 6 and at least two gas burners 7-10. The amount of gas burners 7-10 per arrangement of gas burners 3-5 can be any. As an example, the

 Gas burner arrangement 3 shown on the left in the orientation of Figure 1 presents four gas burners 7-10. The gas burner arrangement 4 arranged in the center in the orientation of Figure 1 has three gas burners 7-9, and the gas burner arrangement 5 shown to the right in the orientation of Figure 1 presents four burners of gas 7-10.

 Henceforth, only the arrangement of gas burners 3 is explained for the sake of simplification. The gas regulating valve 6 is in fluid connection with a main gas conduit not shown from the cooking point 2. A branching gas supply conduit 11 leads from the gas regulating valve 6 to the gas burners 7- 10. The common gas regulating valve 6 is configured to

 regulate a volumetric flow of gas to the gas burners 7-10. The gas burner arrangement 3 also has at least two gas shutoff valves 12-15. The number of gas shutoff valves 12-15 corresponds to the number of gas burners 7-10. The gas shut-off valves 12-15 are configured to interrupt or unblock the volumetric flow of gas, supplied by the gas regulating valve 6

 common, towards the respective 7-10 gas burner.

As Figure 2 shows, the cooking point 2 has several cooking areas 1618, each of which is bordered with a broken line. In this case, a gas burner arrangement 3-5 is assigned to each cooking area 16-18. By way of example, the gas burner arrangement 3 is assigned to the cooking area 16,

 cooking area 17 is assigned the gas burner arrangement 4, and to the cooking area 18 the gas burner arrangement 5 is assigned.

Figure 3 shows the cooking point 2, where a cooking product container 19-29 is placed on each of the gas burners 7-10 of the gas burner arrangements 3-5. In this case, for example each cooking product container 22, 23, 26 and 27 of the cooking area 16 is heated with the same burner power, since the fuel gas stream to the burners 7-10 of the arrangement of Gas burners 3 is directed with the common gas regulating valve 6.

Figure 4 shows another case of application of cooking point 2, in which the containers

 of cooking product 19-22 are arranged on the cooking point 2. On the cooking area 17 two smaller cooking product containers 19, 20 are supported, while on the cooking areas 16, 18 two cooking containers are placed of cooking product 21, 22 large. The gas burners 7, 8 not covered by the cooking product containers are separated from the gas stream

 fuel through gas shut-off valves 12, 14.

Figure 5 shows a cooking product container 19 that is placed on all of the three cooking areas 16-18. So that gas does not escape from the gas burners 7, 9, 10 not covered by the cooking product container 19, these are separated from the combustible gas stream by the gas shut-off valves 12, 14, 15.

 Figure 6 shows in schematic section view the arrangement of gas burners 3 with the gas burner 7 and the gas shut-off valve 12. The gas burner 7 has a burner head 30 and a burner housing 31 with a gas injector 32. Through the gas supply conduit 11, fuel gas 32 is supplied to the gas injector 32 which is mixed with primary air in a mixing chamber 33 of the housing of

 burner 31. The gas shut-off valve 12 is positioned between the gas regulating valve 6 and the gas burner 7 in relation to a direction of the fuel gas stream of the gas regulating valve 6 towards the gas burner 7.

The gas shut-off valve 12 has an actuation element 34, which is in the form of a bar. Preferably, the drive element 34 has a

 circular cross section. The actuation element 34 is positioned such that a central axis 35 thereof is arranged parallel to a central axis 36 of the gas burner 7. To alternatively open or close the gas shut-off valve 12, the actuation element 34 It is movable from an open position shown in Figures 6 and 7 to a closed position shown in Figure 8.

 As shown in Figure 8, the drive element 34 is spring pre-tensioned in the direction of the closing position by means of a spring device 37. By way of example, the spring device 37 is a helical or cylindrical spring, and is positioned between a valve housing 38 of the gas shut-off valve 12 and the actuating element 34. The actuating element 34 is housed in the valve housing 38, at least in sections. On a front side 40 of the drive element 34, a housing drain 39 may be provided, in which the spring device 37 is housed, at least in sections, in the closed position shown in Figure 8, and by

 complete in the open position shown in figures 6 and 7. In the open position of the gas shut-off valve 12, shown in figures 6 and 7, the front side 40 of the actuating element 34 rests on a bearing surface 41 of the valve housing 38.

The gas shut-off valve 12 can also have a damping element 42 that dampens and / or retards a movement of the actuating element 34 when moving

 this from the open position to the closed position.

To move the drive element 34 from the closed position shown in Figure 8 to the open position shown in Figures 6 and 7, a force F can be applied on a front surface 43 of the drive element 34, pushing said force F to the actuating element 34 inside the valve housing 38 of the gas shut-off valve 12 against a spring force of the spring device 37. By way of example, the force F can be applied by one of the product containers of cooking 19-29. When the cooking product container 19-29 is removed from the drive element 34, the drive element 34 automatically moves from the open position to the closed position, the damping element 42 damping the movement of the drive element 34. Also , the damping element 42 provides a delayed movement of the drive element 34 from the open position to the closed position. In this way, by removing the cooking product container 19-29 from the actuating element 34 for a short time it is possible to prevent the influx of gas directed towards the gas burner 7 from being interrupted immediately. By way of

 For example, the damping element 42 may be configured to hold the actuating element 34 in the open position for a few seconds after the cooking product container 19-29 is removed.

To each gas burner 7-10 of the cooking point 2 is associated a pot holder 44 (Figure 6). The pot holder 44 has the drive element 34 and at least two spacers 45, 46 (Figure 1). Preferably, the spacers 45, 46 are made in the form of a bar and are arranged perpendicularly to a cooking field plate 47 of the cooking point 2. A central axis 48 of the spacers 45, 46 is preferably arranged parallel to the axis center 35 of the drive element 34 and to the central axis 36 of the gas burner 7. A height h44 of the spacers 45, 46 is

corresponds to a height h34 of the drive element in the open position above the cooking field plate 47. The pot holder 44 can have any number of spacers 45, 46, although it has at least two spacers 45, 46. The drive element 34 and the at least two spacers 45, 46 are

5 arranged around the respective gas burner 7-10 preferably annularly and, preferably, are arranged around the corresponding gas burner 7-10 evenly.

Although the present invention has been described by means of embodiments, it is modifiable in various ways.
