Definitions

  • the invention relates to a cooking appliance according to the preamble of claim 1.
  • the invention relates to a cooking appliance containing at least one hotplate with a gas heating device which has at least one gas burner, the heating output of which can be set between a minimum gas heating output and a maximum gas heating output.
  • a gas burner for such a cooking device which has two coaxially arranged flame rings which can be supplied individually or together with gas in order to be able to set the gas burner between a minimum and a maximum gas heating output. Depending on the setting, only one flame ring or the other flame ring or both flame rings is switched on or off at the same time.
  • Gas cookers have the advantage that their heat is quickly available when switched on. However, they have the disadvantage that the gas flames cannot be made arbitrarily small, but that the flame goes out when the amount of gas supplied falls below a certain minimum. As a result, the smallest adjustable gas heating output is limited to a value at which the gas flames are small but do not go out.
  • gas burners and gas actuators are designed for the reliable, lowest burner output. As a guideline for the lowest burner output, depending on the type of gas, approximately 1/6 of the nominal output of the gas burner applies. This means that the smallest possible adjustable gas heating capacity depends on the maximum possible gas heating capacity of the burner. It has also been proposed to supply the gas burner with pulsating gas by means of an electronic control in combination with solenoid valves, so that the gas flames are switched on and off in a pulsating manner.
  • the smallest possible gas heating capacity of approximately 1/6 means that it is 17% of the maximum adjustable gas heating capacity. This value is 17% very high compared to electrical heating devices in which a minimum electrical heating power down to only 6% of the maximum electrical heating capacity, with electronic control even only 3% of the maximum electrical heating capacity.
  • the gas heating output which can be set as small as possible is too high for gas burners for many cooking processes for cooking food, for example for finishing small amounts of food, for melting butter, for keeping food warm and the like.
  • a cooking appliance can be, for example, a cooker, a hob with one or more gas burners or a hotplate with one or more hotplates, each of which is provided with at least one gas burner.
  • the devices can be stand-alone devices or built-in devices.
  • the object of the invention is to provide a cooking appliance which is structurally simple and inexpensive and which has the advantages of a gas heating device and can be set to a significantly lower heating output than known gas cooking appliances.
  • a cooking appliance according to the invention is characterized in that the at least one hotplate has, in addition to the gas heating device, an electric heating device with at least one electric heating element, the heating power of which is between a minimum electric heating power and a maximum
  • Electric heating power is adjustable, and that the minimum electric heating power is less than the minimum gas heating power.
  • the invention enables a cooking appliance which has a hotplate with a gas heating device to be reduced without expensive and complicated constructions.
  • the heating output is reduced as far as is possible with electric cooking appliances, ie up to about 3% of the maximum adjustable heating output.
  • the invention can also be used for cooking appliances with very large gas burners, e.g. B. so-called wok burners.
  • very large gas burners e.g. B. so-called wok burners.
  • the advantage of the invention is particularly noticeable when the cooking appliance has only a single hotplate.
  • a pan support with integrated electric tubular heater covers the main performance range.
  • the electric tubular heater preferably has direct contact with the bottom of a pot that can be placed on the hob.
  • the electric tubular heater can be switched on manually from the minimum setting of the gas heating output range. This turns the gas burner into an electric hob.
  • the heating power can be set and regulated in a known manner by energy regulators both when operating as a gas combustion station and when operating as an electric hob.
  • a gas burner with an integrated electric tubular heater Burners are particularly suitable for this purpose, which are simultaneously designed as pan supports.
  • the tubular heater can be integrated in the gas burner or attached to it.
  • FIG. 1 schematically shows a plan view of the hotplate of a cooking appliance according to the invention
  • 3 shows a detailed front view of the cooking appliance with a manual setting element for setting the heating power
  • 4 shows a heating power diagram
  • FIG. 5 shows a broken top view of a further embodiment of a cooking appliance according to the invention
  • FIG. 6 is a broken side view of the cooking device of FIG. 5,
  • FIG. 7 shows a broken top view of a further embodiment of a cooking appliance according to the invention.
  • FIG. 8 shows a side view of the cooking device from FIG. 7
  • the cooking device 2 according to the invention shown in FIGS. 1, 2 and 3 contains at least one hotplate 4 with a gas heating device 6 which has a gas burner 8 which has at least one, preferably two or more flame rings, which are formed by gas outlet openings 10 the gas heating device can be set on a manual setting element 12, for example a rotary knob, between a minimum gas heating power and a maximum gas heating power
  • the at least one hotplate 4 has an electric heating device 14 which has at least one electric heating element 16, the heating power of which can be adjusted between a minimum electric heating power and a maximum electric heating power, the minimum Electric heating power is less than the minimum gas heating power of the gas heating device 6
  • the electric heater 16 for example a tubular heater, surrounds the gas burner 8, for example in a ring and preferably at a constant distance
  • the upper surface of the electric heater 16 is designed as a heat transfer surface and a storage surface onto which a vessel in the form of a Pot or a pan for heating or cooking food and / or drinks is adjustable
  • the electric heater 16 is inserted into upper recesses 20 of arms 22 of a pot support 24 and is supported by this pot support 24.
  • a vessel which can be placed on the hotplate is thus mainly carried by the pot support 24, while the contacting of the bottom of the vessel with the electric heater 16 is only for Heat transfer to the pot is used
  • the electric heater 16 is integrated in the pot support 24
  • the operating element 12 has a gas setting area I marked on the operating panel 26 for the gas heating device 6 with its gas burner 8 and an electrical setting area II for the electric heating device 14 with its electric heating element 16
  • the two setting ranges I and II are arranged one after the other on a defined path of movement of a tip 28 of the setting element 12.
  • the lowest gas heating power is adjacent to the highest electric heating power.
  • Both border on the one marked "1/6" Place on each other and with the control element 12 is optionally switchable from the lowest gas heating output to the highest electrical heating output at the point labeled "1/6".
  • the adjustable maximum gas heating output is labeled "1/1" at the other end of the gas setting range I.
  • the low The best electrical heating output is labeled "6/100" at the other end of the electrical setting range II
  • FIG 4 shows a diagram in which the rotation angle " ⁇ " is plotted on the horizontal axis, to which the setting element 12 can be adjusted.
  • the heating power "P” is plotted on the vertical axis of the diagram.
  • the rotation angle range is at first on the horizontal axis Setting range I of the gas heating power and divided into the second setting range II of the electric heating power.
  • the gas heating power on the control element 12 is reduced above the smallest, predetermined setting value of, for example, “1/6” of the maximum value “1/1”, the gas supply to the gas burner 8 is automatically interrupted at this point and the electric heater 16 is switched on instead, and that to its highest electrical heating output value. From this, it can be reduced on the control element 12 to a predetermined minimum electrical heating power value of z. B. "6/100". If the heating power is further reduced, the device on the manual control element 12 is automatically switched off. The performance range can of course also be covered from the minimum electrical heating output value to the maximum gas heating output value.
  • the ignition of the gas flowing out of the gas burner 8 does not take place only when the maximum gas heating power value is set to “1/1”, but of course during the transition from electric heating mode to gas mode if the setting of the smallest possible gas heating power of z. B. "1/6" of the maximum heating output value "1/1" is reached or exceeded.
  • an adjustment option can be provided for a rapid cooking zone in order to simultaneously switch on the burner 8 of the gas heating device 6 and the electric heating element 16 of the electric heating device 14 in order to generate a heating power which is greater than the highest heating power of the gas heating device.
  • Such an adjustment possibility can be given, for example, by the adjustment element 12 having a third rotation range for this purpose or being axially adjustable in order to make this adjustment.
  • Pot support 24-2 a gas burner 8 with one or more rings of gas outlet openings 10 and at least one electric heating element 16 are integrated. Instead, the radiator 16 can also be attached to the pot support 24-2 instead of integrated. In both cases, the gas heating device 6 forms with the Gas burner 8 and the electric heater 14 with the electric heater 16 together with the pot support 24-2 a structural unit.
  • FIGS. 7 and 8 show a further embodiment of the invention, in which the at least one electric heating element 16 is integrated in a pot support 24 and surrounds a gas burner 8 of the gas heating device 6 at a constant distance.
  • the electrical heating power and the gas heating power can be adjustable by the same control element 12 or, as shown in FIGS. 7 and 8, by an adjusting element 12-1 for the gas heating device 6 and a further adjusting element 12- 2 for the electric heating device 14.
  • the electric heater 16 contacts the bottom or a side wall of a vessel that can be placed on it, e.g. B. pot or pan. According to another embodiment, there may also be a distance between the radiator 16 and the vessel, but this affects the rate of heat transfer.
