Definitions

  • the invention relates to a gas cooking appliance with at least one gas hob with a gas burner and a method for operating such a gas cooking appliance.
  • JP 2006-097973 A is a generic gas cooking appliance known with several gas hobs, each having a gas burner and which is also associated with a switching device. Depending on a switching state of the switching device, a gas supply to the associated gas burner can be blocked or opened and the ignition can be released to the gas burner.
  • the switching state of the switching device is dependent on whether a cooking vessel is placed on the associated gas hob or not. If there is no cooking vessel on the gas hob, the gas supply to the gas burner is blocked and the ignition of the gas burner is not possible. If, however, a cooking vessel is set up, the gas supply can be released and the gas burner can be ignited.
  • a plunger mechanism is provided with a plunger, which can be moved by placing the cooking vessel on the gas hob along a Betjansweges down. If the pestle is in a lower position along the actuation path when the cooking vessel is set up, a switch is actuated and the gas supply to the gas burner of the cooking place, on which the cooking vessel is arranged, is released. If the cooking vessel is removed from the gas hob, the plunger moves back up to a rest position in which a plunger top is located above a cooking vessel footprint.
  • the object underlying the invention is to provide an aforementioned gas cooking appliance and a method for operating such a gas cooking appliance with which problems of the prior art can be eliminated and in particular a required amount of movement of the plunger along the actuating path for changing the switching state can be reduced ,
  • An inventive gas cooking appliance has at least one gas hob with a gas burner and at least one switching device associated with the gas hob.
  • the switching device has a switch and an elongate plunger for switch operation.
  • the straight plunger is arranged in the region of the gas burner of the associated gas hob and has a plunger bottom and a plunger top. It is movable in its longitudinal direction along a Betjanistsweges.
  • the plunger is further configured to actuate the switch when the plunger bottom is in a switch actuation position along the actuation path, and operatively connected to the switch.
  • a position of the plunger bottom along the actuation path can be achieved by moving the entire plunger along this actuation path and / or by changing a plunger length while the position is unchanged the plunger top are changed.
  • the ram length is determined by the distance between the plunger bottom and the plunger top.
  • the plunger can be moved by placing a cooking vessel on the gas hob by a first amount of movement along the actuation path. In this case, the plunger is moved starting from a rest position by a mechanically generated amount. In this case, the plunger is in the rest position when its plunger top is located above a cooking vessel footprint when the plunger thus protrudes with its plunger top to a supernatant above the cooking vessel footprint. The plunger is thus moved mechanically around this supernatant.
  • the plunger bottom is moved by a length increase by a second amount of movement along the actuation path.
  • the plunger is arranged in the region of the gas burner and thus in its heat zone, preferably at a distance of less than 10 cm from the gas burner, it can be heated to the predefined switching temperature by the operation of the gas burner.
  • the quiescent temperature is exhibited by the plunger when not heated by the operation of the gas burner, and is usually at room temperature.
  • the switch operating position is present when the plunger bottom has been moved together from the rest position by the first amount of movement and the second amount of movement together.
  • the switch is not already triggered by the erection of the cooking vessel, which mechanically causes a movement of the plunger along the actuation path, but additionally a thermally generated increase in length of the plunger is required by the second amount of movement. Likewise, the thermally generated increase in length of the plunger alone is advantageously not enough for the switch operation.
  • the gas cooking appliance has a control device and a gas valve, which can be controlled by the control device, wherein the control device is designed to control the gas valve in response to a switching state of the switch.
  • the control device is designed to control the gas valve in response to a switching state of the switch.
  • it is possible to open or block a gas supply to the gas burner by means of the gas valve as a function of the switching state. It is alternatively or additionally possible, depending on the switching state of the switch to control a control valve and to change the gas supply to the gas burner, preferably to reduce. If there is no cooking vessel on the gas hob, the plunger bottom is not in the switch actuation position and the switch is in an idle state, so that the gas supply to the gas burner of this hotplate can be blocked or reduced.
  • this predefined time is dimensioned so that the plunger without setting up a cooking vessel on the gas hob within this time can not heat to the switching temperature and thus does not reach the required length increase. But if a cooking vessel placed on the gas hob, a radiation of the gas burner outgoing heat is prevented upwards through the bottom of the pot or cooking vessel by a heat zone or bubble forms, so that the plunger can reach the required switching temperature.
  • the plunger has a shape-memory metal or a thermo-bimetallic spring, in particular in the region of the plunger bottom.
  • the plunger can also be a thermo-bimetallic spring have on its plunger bottom and in another area a shape memory metal.
  • thermal bimetals are understood as meaning layer composite materials which have at least two components with different coefficients of expansion.
  • a heating of the bimetallic strip leads to the fact that one component expands more than the other, so that a temperature-dependent curvature of the bimetallic strip is formed.
  • the first mechanical movement amount is a maximum of 3 mm to 5 mm.
  • the switch actuating device for transmitting the amount of movement of the plunger bottom to the switch on a lever with two free lever ends.
  • the lever between the two lever ends is rotatably mounted.
  • One of the two lever ends facing the plunger so that the lever can be actuated by moving the plunger and / or the plunger bottom along the actuation path.
  • the plunger facing the first lever end is movable in the same direction as the plunger and consequently the second lever end in the opposite direction.
  • a puller wire which is connected to the switch to transmit the movement of the plunger or the plunger bottom via the lever to the switch and to actuate this, when the plunger bottom is in the switch operating position.
  • the pull wire consists at least in sections of a shape memory metal.
  • the pull wire is completely made of a shape memory metal.
  • shape-memory metals which are also referred to as shape memory alloys, are alloys which have a temperature-dependent stress-strain characteristic.
  • shape-memory metals have a martensitic structure at lower temperatures and, at higher temperatures, above a transition temperature, an austenitic structure. Both phases differ very strongly in their properties. In the austenitic state, these alloys generally have stress-strain characteristics similar to those of conventional alloys.
  • a change in shape or an elongation initially takes place only by a displacement of the highly mobile twin boundaries and not as usual by dislocation movements, so that high strains can already be achieved for small stresses. This means that even with low tensile forces a relatively large change in length can be effected. This effect is also called a superelastic effect.
  • Known shape memory alloys include NiTi, CuZnAl and CuAlNi.
  • a pull wire made of a shape-memory metal as a transmission means or actuator for transmitting a movement of the lever to the switch has the advantage that even with small forces or deflections a sufficient change in length or sufficient pulling action can be achieved for switch operation , This can also be transmitted over a certain distance to the remote switch. Furthermore, the friction, in particular at deflections, can be reduced.
  • the switch is arranged in an area outside the heat zone of the gas burner, preferably with at least 10 cm to 15 cm distance to the gas burner.
  • the plunger top is formed by a rotatably mounted rolling elements, preferably by a ball.
  • the plunger has a ball rotatably mounted in all three directions in space on its plunger top.
  • the plunger has a temperature sensor for detecting a cooking vessel bottom temperature of the cooking vessel erected on the gas hob.
  • the temperature sensor is preferably arranged on the plunger upper side and contacts a cooking vessel bottom of a cooking vessel erected on the gas hob.
  • the gas cooking appliance has a sinking device by means of which the plunger and / or the entire switching device is at least partially, preferably completely, retractable. So it can be stowed almost completely, for example, optical Reasons or for easier cleanability.
  • the sinking device is in particular designed so that the plunger experiences no movement along the actuation path when sinking.
  • a lock can be triggered by the sinking of the plunger to block the gas supply to the gas burner.
  • the gas supply can be disabled after the limited predefined time, when the cooking vessel is removed from the gas hob or has been removed, so that the plunger has moved back to the rest position by the first amount of movement.
  • a lighting of a control element is turned on to indicate to an operator, for which gas hob, the gas supply is permanently enabled when the switch is actuated.
  • the gas cooking appliance has at least one illuminated control element assigned to the gas hob. This lighting of the control element can be activated in dependence on the position of the plunger bottom along the actuating path.
  • the lighting of the control element is turned on when the plunger bottom is in a position along the actuation path in which a current total amount of movement of the plunger bottom is equal to or greater than the rest position by setting up a cooking vessel can be generated on the gas hob first movement amount.
  • the gas burner is turned off only when the plunger bottom is longer than a predefined Bachzündzeit in the position along the actuating travel, in which the current total amount of movement of the plunger bottom relative to the rest position less than the total amount of movement of Switch actuation position is and within this Bachzündzeit no confirmation input of the operator has been made.
  • This reignition time can be about 20 to 30 seconds.
  • the cooking vessel bottom temperature is detected and the gas supply to the gas burner blocked when the cooking vessel bottom temperature has reached a critical temperature and / or a characteristic for a selected cooking process predefined temperature.
  • Fig. 1 shows an embodiment of a gas cooking appliance 100 according to the invention with a plurality of gas wells 109a-c, each gas hob 109a-c having a gas burner, not shown here.

  • each gas hob 109a-c is associated with a switching device only partially shown here, which, inter alia, a plunger 135 and for each gas hob 109a-c has a switch 114a-c, see Fig. 2
  • the switches 114a-c are advantageously microswitches and connected to the control device of the gas cooking appliance.
  • the switches 114a-c are preferably located outside a heating zone of the respective gas burners of the gas cooking zones 109a-c or within the control device.
  • the gas cooking appliance further comprises a controller 113 to control the shut-off and control valves of the individual gas hobs 109a-c to set a desired gas flow rate to the gas burner or to shut off the gas supply to the gas burner.
  • the gas cooking appliance 100 also has operating elements 115 for setting a desired burner output of the respectively associated gas cooking points 109a-c.
  • Fig. 2 shows by way of example a section along the sectional plane AA 'in the region of the gas hob 109a.
  • the gas hob 109a has a pot carrier 125 for setting up a cooking vessel on the gas hob 109a.
  • a gas burner 127a In the center of the gas hob 109a is a gas burner 127a, in the center of which in turn a plunger mechanism 131 with the plunger 135 is arranged.
  • the plunger mechanism 131 can also be arranged laterally on the gas burner or in another position in the region of the gas burner.
  • the pot carrier 125 and the gas burner 127a and a part of the plunger mechanism 131 are located above a hob surface 123, while the other part of the plunger mechanism 131 and the cable 111 ac are 111 in the area below the hob surface 123.
  • the plunger 135 is shown in a rest position in which it protrudes with its plunger top up on the cooking vessel footprint 129 by a first amount of movement H mech or a mechanically generated stroke.
  • the plunger 135 is vertically displaceable within a cylindrical housing 133 along a Betschistsweges. If a cooking vessel is placed on the gas hob 109, then the plunger moves downwards by the first amount of movement H mech or the mechanically producible stroke. However, this first amount of movement H mech is not sufficient to move a lever 137 sufficiently far, which serves to transmit a plunger movement to the switch 114 a, not shown here.

In this case, the plunger on the plunger length L 1 , if he has the predefined switching temperature, see Fig. 3 , The heating of the plunger 135 takes place during operation of the gas burner 127a.
  • the plunger 135 is arranged in the region of a heat zone of the gas burner 127a, ie closer than 10 cm to the gas burner 127a, then it heats up very rapidly. So in a short time starting from a rest temperature reaches the predefined switching temperature and thus the required increase in length to achieve a switch operating position of the plunger bottom. Then, the switch 114a is actuated due to the sufficient overall movement of the plunger bottom, as will be explained below.
  • Fig. 3 shows a section through the gas cooking appliance along the sectional plane AA 'in the region of the gas hob 109a according to Fig. 2 but with a cooking vessel 147 set up on the gas hob 109a.
  • the cooking vessel 147 moves the plunger 135 vertically down the actuating travel within the cylindrical housing 133 by the first amount of movement H mech . If the gas burner 127a is then ignited, heating of the plunger 135 occurs as a result of the heat released by the burner and stowed under the cooking vessel 147, so that the aforementioned increase in length of the plunger 135 is effected by the plunger length L 0 on the plunger length L 1 .
  • the plunger bottom has been thermally moved a total of the first mechanically generated amount of movement H mech plus the second thermally generated amount of movement H and is thus in the switch operating position.

  • the plunger bottom is then no longer in the switch operating position.
  • the lever 137 has moved back to its original position and thus the switch 114a is no longer actuated.
