Definitions

  • the invention relates to an extinguishing device for fighting fires in burning pots, such as deep fryers, fondue pots or the like.
  • the invention provides an extinguishing device which is simple and nevertheless effective, especially for fighting fires in burning pots, such as deep fryers, fondue pots or the like. Household pots and can be readily available, for example, in the kitchen on the stove.
  • the extinguishing device according to the invention is designed as a plate which can be placed on the rim of the pot or which is deformable and which can be placed over the pot, made of a flame-proof, airtight material with a handle on the side.
  • the extinguishing device is particularly suitable for suffocating the flames in burning pots and can be kept within reach, for example, in the kitchen or in another easily accessible place. If necessary, it is grasped on a stick and placed with the rim of the plate on the edge of the burning pot or with the hood over the burning pot, so that further flames are prevented and the interior of the burning pot largely against this Inflow of air is shielded so that the flames suffocate.
  • the hood size is adapted to the pot sizes customary in the household.
  • the hood diameter is preferably larger than the rim of the pot, so that the hood, even if there are handles arranged on the rim of the pot or parts protruding laterally from the pot, such as a handle of a deep-fryer basket or the like, over the pot and the protruding parts can be put over.
  • the hood depth can be so great that the flipped hood envelops the burning pot over a substantial part of the pot height.
  • hood depth it is also possible to make the hood depth much larger, so that the hood edge extends with the hood slipped on to the base on which the burning pot is standing, so that the hood edge can be pressed sufficiently tightly against the base for extensive air exclusion. If the hood material is stretchable, the hood can be pulled against the edge of the pot if necessary.
  • Suitable airtight, flame-resistant materials which are suitable for the present purpose as a hood material are known per se, so that they do not need to be described in detail here.
  • An airtight, flame-proof, flexible material and / or film material is preferably used as the hood material, it being possible for a woven material material to be impregnated airtight, for example.
  • the hood part thereof is preferably constructed in a bag-like or accordion-like manner and the like, so that the hood part can be folded for storage, but opens automatically when placed over the pot.
  • the extinguishing hood according to the invention can also be designed in such a way that the hood edge of the fitted hood can be placed closer to the outer peripheral surface of the pot.
  • the retaining ring can be designed, for example, in the form of a loop, the ends of which loop converge towards the handle stem with an increasingly smaller distance and can be pulled together by means of a tube which can be displaced on the handle stem, so that the loop-like retaining ring itself contracts.
  • it can also be interrupted on the side facing away from the handle, so that it forms a clamp that can be closed in the above manner.
  • Such rings shrinking under the influence of heat are known per se.
  • a plastic material stretched in its circumferential direction and heat-fixed in this state can be used.
  • Such a ring, which shrinks under the influence of heat can optionally be attached to the edge of the hood so that it can be easily detached, so that it can be exchanged for a replacement ring after use.
  • Such a ring, which shrinks under the action of heat can be displaceably guided, for example, on the retaining ring in an inner groove, so that when the ring shrinks, only its inner diameter, but not the outer diameter of the hood edge, is reduced. It is also possible to make the hood edge deformable, so that it is also contracted when the ring shrinks.
  • a sealing ring made of compressible sealing material can run on the front side and / or inside of the hood edge, which can be designed to be heat-resistant or, if appropriate, can also be formed from the ring which shrinks under the influence of heat.
  • a fire-extinguishing material is detachably held on the inner surface of the hood or plate by the action of heat and / or flame.
  • a customary fire extinguishing powder can be present in a container made of flammable or meltable container material, which is glued or otherwise held under the plate or hood base.
  • OP. WP for example a thermoplastic film. Due to the heat and / or flame effect, the fire extinguishing material is released from the plate or hood bottom and falls into the burning pot, so that the flames extinguish more quickly.
  • Such fire extinguishing materials which can be based, for example, on sodium bicarbonate, are known per se and can optionally be kept available in packs suitable for the present application for replacing a fire extinguishing material used up by the use of the extinguishing device.
  • a safety valve can also be formed on the hood, which prevents an impermissibly high pressure build-up under the hood placed on the burning pot.
  • a simple, possibly spring-loaded, non-return valve can be provided, which opens to the outside of the hood, so that compressed gases can escape from the hood, but the check valve prevents air from entering the hood.
  • the handle attached to the edge of the hood is long enough to be able to put the hood over the burning pot from a sufficient safety distance.
  • the stem can, for example, have a length between 30 and 50 cm. It can be made telescopically extendable up to this length so that it can be pushed together for the storage of the fire extinguisher hood.
  • Hand control device arranged in the handle.
  • a foam spray can e.g. a shaving foam dispensing box, acting fire extinguishing foam dispensing device
  • the fire extinguishing foam can be foamed into the burning pot by actuating the manual actuating device preferably arranged on the handle of the handle, so that the flames quickly suffocate.
  • the dispensing device contains a dispensing nozzle which opens into the interior of the extinguishing device and is connected directly or via a line to a liquid container which is under the pressure of a propellant gas or can be pressurized by means of an associated pressure delivery device and which contains a foamable fire extinguishing liquid.
  • the container can be arranged in the interior of the extinguishing device or in its handle.
  • the liquid container is preferably accommodated so that it can be replaced so that after use it can be replaced by a filled container that is commercially available.
  • the container containing the foamable fire extinguishing liquid is under the pressure of a propellant gas, it can be designed in the manner of the known hand-held spray cans or spray cartridges. If it is only pressurized to dispense the extinguishing foam, the associated pressure delivery device can be designed as a hand pump or, in particular, as a compressed gas cartridge.
  • the extinguishing device can also be designed in the form of a plate provided with a handle, which has a relatively wide plate edge, which is preferably covered with a sealing washer made of flameproof compressible material, and is adapted to the size of conventional household pots is dimensioned such that the fire extinguisher plate can be placed with its rim on the edge of the burning pot. Due to the deformable speed of the elastically compressible sealing washer, which is preferably relatively thick, a sufficiently good sealing effect between the pot rim and the plate rim can be achieved even with relatively low compressive force even if, for example, a deep fryer basket is used in the pot, with its handle from the top of the pot lying on top of it.
  • the extinguishing plate can be designed to be non-deformable overall because it can be made sufficiently flat to store it in a space-saving manner, for example to hang it up on the kitchen wall like a pan or a decorative plate.
  • a plate-shaped extinguishing device can also do without the fire extinguishing foam dispenser, although the inclusion of the fire extinguishing foam dispenser is preferred even when the extinguishing device is in the form of a plate.
  • the handle is preferably inserted or retractable into the interior of the hood or plate, so that it can be inserted or swiveled into this interior for the storage of the extinguishing device and is therefore not visible when the extinguishing device with the hood - or Teller ⁇ edge facing a wall is hung on this wall.
  • the then visible outside of the extinguishing device can be of decorative design, so that the extinguishing device acts like a decorative plate while it is being stored on the wall.
  • the invention is explained on the basis of exemplary embodiments which can be seen from the drawing.
  • the drawing shows: 1 is a fire extinguisher according to the invention in de side view,
  • Fig. 3 in longitudinal section a plate-shaped quenching device according to the invention with the handle inserted into the plate and
  • FIG. 4 shows the longitudinal section of the handle of FIG. 3 in the region of its handle according to the section line in FIG. 3.
  • the hood shown in FIG. 1 is designed as a truncated cone-shaped bellows, for example made of asbestos cardboard or the like, so that it can be folded together along the hood axis.
  • a fixed retaining ring 2 is formed, on which a telescopically adjustable handle 3 is attached laterally, which extends obliquely upwards, so that the hood 1 on its handle 3 can be slipped over a burning pot from above until the The edge of the hood rests on the surface on which the pot is placed.
  • This end face of the hood edge is formed in the embodiment according to FIG. 1 by a sealing ring 7 which is glued under the retaining ring 2.
  • a fire-extinguishing material 4 for example a fire-extinguishing powder in a container made of a thin thermoplastic plastic film, is fastened to the hood base.
  • the container melts due to the effect of heat and / or flame, so that the extinguishing powder falls down into the burning pot and contributes to extinguishing the flames.
  • the retaining ring 2 is formed from a loop-like band material made of spring steel, the ends of the loops being brought together to form the handle stem 3, over which a tube 5 is pushed, so that the tube 5 when the fire-extinguisher hood is held on the handle piece 6 of the handle 3 can be shifted towards the hood part 1 and thereby the loop-like retaining ring 2 contracts while reducing the diameter of the hood edge.
  • a sealing ring 7 made of compressible, heat-resistant sealing material is attached to the hood material.
  • the extinguishing device is formed overall as a plate 10, the plate edge 21 of which is covered on the end face facing away from the plate base with a sealing washer 20 made of a flame-resistant, elastically compressible material, so that the plate 10 can be placed on the edge of a burning pot and the sealing washer rests sealingly on the rim of the pot.
  • the extinguishing plate 10 has a handle 3 made of telescopically insertable tube pieces 12, which extends outwards through a sliding guide in the plate wall, so that its handle 6 protrudes from the outside of the plate wall.
  • the handle 3 can therefore be telescopically pushed into one another and, moreover, can be inserted into the interior of the plate 10 through the sliding guide.
  • the maximum length of the handle is determined by stops not shown.
  • corresponding detents or the like for locking the handle 3 in its extended position may be present.
  • a foam dispensing nozzle 11 is attached to the end of the handle stem 3 located in the interior of the plate 10, at the feed end of which a nipple 22 projecting into the hollow handle stem 13 is formed, on which a feed line designed as a flexible hose or telescopic tube is formed 12, which leads to a pressurized liquid cartridge 19 accommodated in the handle 6 of the handle 3 (FIG. 4), in which a foamable fire extinguishing liquid is contained under the pressure of a propellant gas.
  • the handle 6 is hollow and with one end screwed onto the handle 3, so that the handle 6 for removing an empty cartridge 19 or
  • a full cartridge 19 can be unscrewed from the handle 3.
  • the cartridge 19 is designed in the manner of commercially available pressure spray cans and has at the dispensing end a dispensing nipple (not shown) over which the feed line 12 is pushed.
  • the dispensing nipple is surrounded by an actuating tappet 17 of the dispensing valve of the print cartridge 19.
