Definitions

  • the invention relates to a gas stove with at least one open hob, with at least one stove base having an open top, with at least one burner arranged in the stove, connected via a gas line system in the stove and with a removable insert into the stove, in particular suspended, serving as a drip pan, having a burner opening for the burner hob, the burner having a burner nozzles, removable burner head, a line connector and possibly a pilot light burner and a temperature sensor.
  • Gas stoves with at least one open hob are available in various designs on the market and are used extensively, particularly in the catering sector.
  • the gas cooker known from practice, from which the invention is based, there are two burners in an elongated, upwardly open stove pan in the stove base, which are connected in the stove pan via a gas line system to a valve arrangement and above that to a gas supply line.
  • Each burner has its own hob, which serves as a drip pan and has a burner opening in the middle for the burner. From above, a pan support frame is placed on the edge of the hob and the burners with the cooking hobs surrounding them, which can carry pots of different diameters on frames that protrude inwards from the edge above each burner.
  • each burner is permanently installed in the stove pan, a base of the burner head is screwed onto the open pipe connection piece for this purpose.
  • a pilot flame burner and a temperature sensor are fixed inside the base and open into the gas flow channel in the base.
  • At the upper end of the base there is an annular nozzle holder which is coaxial with the base and on which a likewise annular, removable burner cover which has the burner nozzles itself is placed from above.
  • the so also firmly with the stove connected burner head passes through the burner opening in the hob from below, the burner opening in the hob has a slightly raised edge for this purpose. As a result, liquid or the like caught in the hob is prevented from running into the annular gap between the burner head and the edge of the burner opening in the hob from above.
  • the hob can be removed upwards to clean it without doing anything to the burners.
  • the burner cap can be removed from the nozzle holder anyway to clean it.
  • Even if this construction is quite useful, because food residues, leaked or overcooked liquids, cleaning liquid etc. collect in the hob and the soiled hob can be cleaned separately, for example in a dishwasher, there is still a problem, that through the annular gap between the burner head and the edge of the burner opening in the hob, liquids that boil over relatively often, etc., and contaminate the internals located under the hob in the hob. Cleaning there is tedious and time-consuming because of the various lines, etc.
  • the invention has for its object to further improve a gas stove of the type in question in terms of cleaning technology.
  • the burner head is firmly attached to the hob and closes the burner opening and that the burner head can be removed from the line connecting piece by lifting the hob from the hob.
  • the burner head is firmly connected to the line connection piece and thus to the gas pipe system during operation, but the burner head is structurally assigned to the hob and can be connected to the hob be handled together.
  • the annular gap between the outer circumference of the burner head and the inner edge of the burner opening in the hob can thus be dispensed with, the burner head can be attached directly to the hob, closing the burner opening. This prevents any dirt from getting into the area under the hob. This eliminates a systematic contamination problem of known gas stoves - the entry of dirt into the area under the hob through the remaining annular gap.
  • the burner head is firmly connected to the hob and can be removed from the line connecting piece by lifting the hob from the hob. This does not exclude that an easy-to-use unlocking mechanism for unlocking the burner head from the line connecting piece must be operated before the hob is lifted out of the hob. In certain circumstances, this is useful as a special security measure. Normally, however, it would be sufficient if the burner head connected to the line connecting piece via a plug connection was simply pulled off the line connecting piece.
  • Fig. 1 shows the basic structure of a gas stove with several open hobs. Shown is a stove base 2, which is open at the front and has an upwardly open stove pan 1, on the front of which one can see two control knobs 3 made of heat-insulating material, one switch knob 3 for each hotplate.
  • Fig. 1 one looks diagonally from above into the interior of the hob 1 in the base 2 and recognizes therein a gas pipe system 4 to which two burners 5 are connected in the hob 1. This will be explained in more detail later.
  • a removable insert which can be inserted into the hob 1, particularly which can be hung on the edge, and which has a burner opening 6 for the respective burner 5 and serves as a drip pan 7. 2 to refer.
  • a pan support frame 8 is placed on the cooktop 7, which is carried out continuously for both burners 5, and can support a pan above the respective hotplate in the usual manner via inwardly projecting frames 9.
  • the pot support frame 8 consists here, as is usually also the case, of cast iron, while the hob 7 in the exemplary embodiment shown here consists of stainless steel sheet and is produced using the deep-drawing process.
  • the burner 5 has a burner nozzles 10 having a removable burner head 11, a line connecting piece 12 on the gas line system 4 and, in the exemplary embodiment shown here, an ignition flame burner 13 and one has a thermocouple temperature sensor 14 (Fig. 3).
  • the pilot burner 13 is directed into the main gas duct 15 Generated pilot flame, which sweeps over the temperature sensor 14, by means of which thermoelectric flame monitoring is thus implemented. This is also regularly realized in the prior art and does not require further explanation here.
  • the line connecting piece 12 can be seen in each case in a support plate 16 fixed to the stove pan 1, in which, in the exemplary embodiment shown, the pilot flame burner 13 is also carried with the temperature sensor 14, which of course is only indicated in FIG. 1 is.
  • FIG. 2 makes the design somewhat clearer in a partial section through the area of the hob 7 on the left in FIG. It can be seen that the burner head 11 is still specially sealed with respect to the burner opening 6, which is indicated by the seal which is not provided with reference numerals. Simply plugging the burner head 11 onto the edge of the hob 7 in the burner opening 6, which edge is bent upwards, may not be sufficient in terms of fastening technology. Therefore, in the exemplary embodiment shown in FIG. 2, it is also indicated that the burner head 11 is fastened to the hob 7 by means of a screwed-on clamping piece 17. This ensures, in particular, that the burner head 11 is not pushed out of the line connecting piece 12 when the hob 7 is hooked into the hob 1. Of course, other connection techniques of a conventional type are also conceivable at this point.
  • the line connecting piece 12 could be locked with the associated burner head 11.
  • the illustrated embodiment shows a simple plug connection, which of course must be sealing or largely sealing.
  • the burner head 11 has a sealing plug socket 18 for the line connecting piece 12.
  • the socket 18 is a plug-in socket, correspondingly an ice socket would also be possible.
  • the two sockets 18 of the burner heads 11 are plugged onto the associated line connecting piece 12 in a sealing manner, so that the main gas channel 15 in the two burner heads 11 is connected to the gas line system 4.
  • the guide elements 20 are provided on the hob 1 and the hob 7, preferably on the outer edge.
  • the guide length of the guide elements 20 is greater than the plug-in length of the burner head 11 and the line connecting piece 12.
  • the guide elements 20 are by pins on the underside of the edge of the hob 7 or corresponding Recorded on the edge of the stove 1. They come into engagement with one another in front of the jacks 18 and sockets 19, so that the latter are then brought together precisely.
  • annular nozzle carrier 22 is arranged concentrically on a base 21 of the burner head 11. This has disadvantages in terms of cleaning technology.
  • a further preferred construction is realized, which is characterized in that the nozzle carrier 22 protrudes laterally from the base 21.
  • the free interior enclosed by the nozzle holder 22 is therefore located laterally or essentially laterally of the base 21 and over a free surface of the hob 7.
  • this has the advantage on the one hand that the clamping piece 17 for the burner head 11 is seen from above by means of a tool ( a screwdriver) can be achieved, on the other hand, this has the advantage that the nozzle holder 22 can be washed around on all sides when it is cleaned.
  • the nozzle carrier 22 also carries an annular toroid, which has the burner nozzles 10 and has a removable burner cover 23.
  • handles 24 are provided at the ends.
  • FIG. 1 also represents a preferred exemplary embodiment insofar as each hob 7 is provided for two hotplates and two burner heads 11 are provided at two burner openings 6.
  • a modular system two, four, six cooking zones can be set up using simple means.
  • the hob 7 with the burner heads 11 located thereon can be inserted into a dishwasher as a whole, and thus in one go thorough cleaning of the hob 7 simultaneously with the burner heads 11 located thereon.
  • the burner nozzles 10, which may be even more sensitive to contamination, can be cleaned particularly well since they are located in the nozzle holder 22, which can be removed from the base 21. You come with the hob removed 7 very easy to get to the internals in the hob 1, since at the same time as the hob 7 is removed, the protruding burner heads 11 above the other parts of the burner 5 have disappeared.
