    DESCRIPTION
    Disposition of gas burners, cooking point, and kitchen.
    The present invention refers to an arrangement of gas burners, a cooking point, and a kitchen.
    A cooking point may have an arrangement of gas burners with a gas valve 5, with a gas burner, and with a supply conduit that connects the gas valve with the gas burner. Also, the gas burner arrangement may comprise a thermal element to control the flame of the gas burner. As soon as the gas burner flame applies heat to the thermal element, it will supply electrical voltage to a gas valve magnetic valve. When the flame goes out, the thermal element cools and electric voltage ceases to be applied to the magnetic valve. The magnetic valve closes the gas valve to interrupt the flow of combustible gas from the gas valve directed towards the gas burner. In this way, an unwanted exit of unburned combustible gas is prevented.
    European patent EP 1 251 316 B1 describes an arrangement of gas burners with 15 several gas burners and several gas valves, where a mechanically operable switch is provided in an electrical connection between a respective thermal element of a gas burner and the Gas valve. The mechanically operable switches of all gas burners are mechanically coupled together by means of a connecting piece. When the connecting piece is activated, all the switches are opened at the same time. twenty
    Against this background, the present invention solves the technical problem of providing an improved gas burner arrangement.
    Therefore, an arrangement of gas burners for a cooking point with two or more gas burners is proposed, to each of which a gas valve is associated to regulate a stream of combustible gas directed towards the gas burner and a thermal element 25 for controlling a gas burner flame, where each thermal element is coupled with the gas valve associated therewith by an electrical connection such that, when the gas burner flame goes out, it is interrupted by the valve of gas the combustible gas stream directed towards the gas burner, where each electrical connection has a mechanically operable switch, where the mechanically operable switches 30 are activatable to couple or uncouple the electrical connections between the thermal elements and the gas valves by means of a common actuating element, and where the mechanically operable switches comprise elements of c ontacto that present a precious metal.
    As an example, an electrical connection between the gas valve and the respective thermal element is interrupted by the switch.
    By presenting the contact elements a precious metal, it is possible to achieve a particularly good conductivity of the contact elements. The contact elements may be coated with the precious metal or made entirely of said metal. In addition, the contact elements have very little wear. The mechanically operable switches 40 may be arranged one behind the other, one next to the other, and, for example, one behind the other in pairs. In this way, a particularly compact structure is obtained, and assembly costs can be reduced. In addition, the safety of the operation of the gas burner arrangement is increased. The axial movement of the actuating element causes the simultaneous separation of all the thermal elements 45 from the gas valves.
    According to one embodiment, the contact elements have gold.
    Alternatively, the contact elements may have silver, platinum, rhodium, or the like.
    According to another embodiment, the gas burner arrangement has a connection device that has the mechanically operable switches and the actuating element.
    The drive element is shaped like a bar and has a circular cross section. 5 Next to the drive element, an drive handle can be provided which engages in a drive by means of a flattening provided next to the drive element. The connection device preferably has female sockets or inputs for the thermal elements and other female sockets or outputs for connection with the gas valves. Preferably, the number of inputs corresponds to the number of outputs. 10
    According to another embodiment, the actuating element is prestressed by means of a spring device in the direction of the closed position of the mechanically operable switches.
    The switches are closed in an initial or predetermined position. The spring device is a compression spring and can be a cylindrical spring. fifteen
    According to another embodiment, by moving the actuating element against the elastic force of the spring device, the mechanically operable switches are transferable from the closed position to the open position.
    According to another embodiment, the drive element has a slide guide in which a guide pin provided next to a housing of the connecting device meshes. twenty
    Preferably, the guide pin is spring-pressed and pressed against a groove of the slide guide, being housed in the sliding groove.
    According to another embodiment, the slide guide has an interlocking section in which the guide pin is embedded while the switches are in the open or uncoupled position of their electrical connections. 25
    The interlocking section is made as a cavity or emptying the groove. Since the guide pin is spring pre-tensioned, it engages the interlocking section automatically.
    According to another embodiment, by moving the actuating element in the direction in which the switches are in their open position and being turned simultaneously, the guide pin is automatically movable from the position where the switches are disengaged in their open position to the position where the switches are engaged in the closed position by means of the spring device.
    By moving the drive element in the direction of the open position, the guide pin is preferably raised by being removed from the interlocking section of the groove and, when the drive element is rotated simultaneously, the guide pin is prevented from engaging again. in the interlocking section. The switches are prevented from closing undesirably when necessary to bring the actuator to the closed position by pressing down and, at the same time, rotating the actuator. This increases safety when handling the disposition of gas burners. 40
    The gas burner arrangement is provided with a main switch, which comprises the mechanical switches, the drive element, and the contact elements. Here, a first amount of plug-in connectors may be provided to couple the thermal elements to the main switch by means of cables or the like, and a second amount of plug-in connectors to couple electromechanical magnetic valves to the main switch by means of cables or the like. The first amount is
    it preferably corresponds to the second quantity, so that there is, for example, a one-to-one coupling and decoupling of a respective thermal element with or of a respective associated magnetic valve. This leads to greater reliability and, therefore, greater security of the gas burner arrangement.
    Likewise, a cooking point with an arrangement of exposed type 5 gas burners is proposed.
    The cooking point is preferably part of a household appliance.
    In addition, 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, in particular, a household appliance. 10

    Figure 1 shows a kitchen 1 in schematic top view. Kitchen 1 is a 5 gas cooker and a domestic appliance. The kitchen 1 has a cooking point 2 with an arrangement of gas burners 3, which has two or more gas burners, although the amount of gas burners may be as desired. As shown in Figure 1, the gas burner arrangement 3 can have five gas burners 4 to 8, although, alternatively, it can have, for example, three or four gas burners. A gas valve 9 to 13 is associated with each gas burner 4 to 8. Gas valves 9 to 13 are preferably gas regulating valves, and are configured to regulate gradually or with continuous progression or, alternatively , interrupt, the fuel gas stream or the volumetric flow of gas directed towards the respective gas burner 4 to 8. Each gas valve 9 to 13 is fixed to a main gas conduit 14, preferably 15 is fixed by tightening to the main gas conduit 14.
    Each gas burner 4 to 8 is connected as regards the fluids with the gas valve 9 to 13 associated with it by means of a supply conduit 15 to 19. Also, to each gas burner 4 to 8 a thermal element 20 is associated to 23 (figure 2). Figure 2 shows a connection device 24 with four thermal elements 20 to 23. The arrangement of 20 gas burners 3 may have the connection device 24, which is not shown in Figure 1. The connection device 24 is suitable for an arrangement of gas burners 3 with four gas burners. Alternatively, the connection device 24 may have five or six thermal elements. The amount of thermal elements preferably corresponds to the amount of gas burners. 25
    Each thermal element 20 to 23 is disposed adjacent to the gas burner 4 to 8 associated therewith. In Figure 2, the thermal elements 20 to 23 are shown in an unmounted state, that is, the thermal elements 20 to 23 are not yet arranged in Figure 2 adjacent to the gas burner 4 to 8 associated therewith. By way of example, the thermal elements 20 to 23 can be immobilized in each case together with a lower part 30 or burner housing of the corresponding gas burner 4 to 8, or be fixedly connected with it in another way.
    Each thermal element 20 to 23 is configured to control a flame 25 (Figure 3) of the gas burner 4 to 8 associated with the respective thermal element 20 to 23. As shown in Figure 3, each thermal element 20 to 23 is coupled with the gas valve 9 to 13 associated with it by an electrical connection 26 such that, when the flame 25 of the gas burner 4 to 8 goes out , by means of the gas valve 9 to 13 the fuel gas stream directed towards the gas burner 4 to 8 is automatically interrupted. If there is a flame 25 in the gas burner 4 to 8, the thermal element 20 to 23 generates an electrical voltage whereby the gas valve 9 to 13 is kept in an open state, for which the gas valve 9 to 13 40 can comprise a magnetic valve. As soon as the flame 25 of the gas burner 4 to 8 goes out, voltage is applied to an electromagnet of the magnetic valve, and the gas valve 9 to 13 interrupts the flow of combustible gas directed towards the gas burner 4 to 8. Each electrical connection 26 has an electrically operable switch 27. In an initial or predetermined state, the mechanically operable switches 27 are closed.
    If the flame 25 of the gas burner 4 to 8 is detected, each thermal element 20 to 23 is configured to transmit a continuous signal to the gas valve 9 to 13 associated therewith. If the flame 25 of the gas burner 4 to 8 goes out, the thermal element 20 to 23 is further configured to interrupt the continuous signal, so that the gas valve 9 to 13 50
    interrupts the flow of combustible gas directed to the gas burner 4 to 8. Each mechanically operable switch 27 of each electrical connection 26 is configured to interrupt the continuous signal of the thermal element 20 to 23, so that the gas valve 9 to 13 interrupt the flow of combustible gas directed to the gas burner 4 to 8.
    Figure 2 shows the connection device 24, which presents the mechanically operable switches 27 5 and an actuating element 28. The connection device 24 can be considered the main switch of a gas cooker. There is talk of a main switch or main switch, since, by means of the drive handle and the drive element described below, the operation of the gas burners or, in other words, of the gas cooker, can be started or interrupted The drive element 28 is preferably bar-shaped and may have a circular cross-section. Next to the actuating element 28, an actuating handle 29 preferably fixed in a torsion-resistant manner is provided. The connection device 24 has a housing 30 with a female plug 31 in which a cable harness 32 with a plug-in element 33 is pluggable. The cable harness 32 has several lines of connection 15 34 to 37 to connect the connection device 24 with the connection valves 9 to 13. In addition, female plugs 38 to 41 are provided next to the housing 30 to plug the thermal elements 20 to 23. The female plugs 38 to 41 can be arranged next to each other and / or one on top of the other
    Figure 4 shows the connection device 24 in a schematic view exploded in perspective. The housing 30 of the connection device 24 has a rear part 42 of the housing and a front part 43 of the housing. The rear part 42 of the housing can be screwed with the front part 43 of the housing by means of a screw 55. Each of the mechanically operable switches 27 comprises contact elements 44, 54 having a precious metal. In the housing 30 a first support 56 is housed, which 25 supports the contact elements 54, and a second support 57, which supports the contact elements 44. The supports 56, 57 are relative relative to each other, in specifically, they can move closer or further away from each other, to close or open the switches 27.
    As shown in Figure 5, the second support 57 is spring pre-tensioned in the direction of the first support 56 by several spring devices 58. The spring devices 58 30 are preferably compression springs, and four spring devices 58 are provided. Preferably, one or more contact elements 44, 54 are assigned to each mechanically actuated switch 27. As shown in Figure 4, two contact elements 44, 54 can be associated to each mechanically actuated switch 27. The contact element Contact 44, 54 may, by way of example, present gold, silver, platinum, or similar precious metals. The mechanically operable switches 27 may be arranged next to each other and / or on top of each other.
    The connection device 24 according to Figures 3 to 5 has four electrical connections 26. The mechanically operable switches 27 of the electrical connections 26 are activated to interrupt the electrical connections 26 between the thermal elements 20 to 23 and 40 the gas valves 4 to 8 by means of the common actuating element 28. Preferably, the drive element 28 has a flat section 45 in a final section in which a gear section of the drive handle 29 is engaged in a drive. Next to the second final section of the drive element 28 is provided a slide guide 46 with a guide groove 47. A spring-loaded guide pin 49 45, screwed into a cylindrical housing section 48 of the front portion 43 of the housing 30, extends into the interior of the guide groove 47.
    The actuating element 28 is prestressed by a spring device 50 in the direction of the closed position of the mechanically operable switches 27. The spring device 50 is preferably a compression spring. Also, the device 50
    spring 50 is fitted on a housing section 51 of the drive element 28, and housed between the drive element 28 and a support section 52. The support section 52 is coupled with the second support 57 such that, at If the actuating element 28 is pressed down against an elastic force of the spring device 50, the mechanically operable switches 27 are opened. Another spring device 59 is arranged between the front part 43 of the housing 30 and the support section 52.
    Therefore, by moving the actuating element 28 against the elastic force of the spring device 50, the mechanically operable switches 27 are translatable from the closed position of their electrical connections to the open or uncoupled position of their 10 electrical connections. The slide guide 46 has an interlocking section 53 in which the guide pin 49 engages in the open or electrically decoupled position (Figure 5). By moving the actuating element 28 in the direction of the open position and being turned simultaneously, the guide pin 49 can be automatically moved from the open position to the closed position by the spring device 50. The device 5 is shown in Figure 5 15 of connection 24 in the open position, in which the spring-pressed guide pin 49 fits into the interlocking section 53.
    Figure 6 shows an embodiment of a connection device 24 suitable for an arrangement of gas burners 3 with six gas burners.
    Figure 7 shows an embodiment of a connection device 24 suitable for an arrangement of gas burners 3 with five gas burners.
    Figure 8 shows the connection device 24 according to Figure 6 in schematic perspective view.
    Figure 9 shows an embodiment of the switch 27 mechanically operable with the contact elements 44, 54. In this embodiment of the switch 27, the contact element 25 is in the form of a pin or pin, and the contact element 54 is shaped like a sheet or sheet. The contact element 54 may be made as a spring.
