Definitions

  • the invention relates to a fire protection and fire extinguishing device for water-bearing domestic appliances.
  • the arrangement may be such that the containers, preferably several, each containing fire extinguishing cells, which conveniently have holes in the bottom area, which are closed by a protective cover or a membrane-like cuticle, or at a predetermined temperature for Opening the holes is destroyed and this allows the fire extinguishing material escape.
  • the object of the present invention is therefore to provide a fire protection and fire extinguishing device for a water-conducting domestic appliance, which takes measures already at the beginning of a malfunction with potential fire sequence for the domestic appliance measures to protect both the domestic appliance from further damage, as well as a fire hazard and prevent to extinguish a fire that has arisen.
  • the fire protection and fire extinguishing device for water-bearing household appliances ensures that a smoldering fire, an open fire or smoke is detected and the water-bearing domestic appliance is disconnected immediately from the electrical network and thus taken the electrical ignition energy for the fire or smoldering fire becomes. If a fire breaks out, the water spray system will continue to be activated in order to extinguish fires, for example, by a spray.
  • the fire protection and fire extinguishing device according to the invention for water-bearing household appliances are the first level of security through the gas sensor smoke developments, which are mainly due to polyethylene (PE), polypropylene (PP), polyamide (PA), polyvinyl chloride (PVC) or polystyrene (PS) , recognized early, as carbon monoxide (CO) and / or chlorine (CI) is released when burning these plastics.
  • the power cutoff prevents overcurrents from leaking to or from neighboring electrical devices that are in the same circuit.
  • the water spray system is activated and generates, for example, a spray or the like in the interior of the water-bearing household appliance.
  • a fire protection and fire extinguishing device for a water-bearing household appliance which takes measures already at the beginning of a malfunction with potential fire sequence for the domestic appliance measures to protect both the household appliance from further damage, and to prevent a fire hazard and a resulting fire to delete.
  • the gas sensor is arranged in the floor area and / or a door of the household appliance.
  • a gas sensor 2 is arranged in the embodiment shown, which is associated with a gas sensor circuit, and electrical conductors with a relay 3, in the illustrated embodiment, a bistable relay 3, so that in a signal of the gas sensor 2, the main circuit all-pole is interrupted and the dishwasher 1 is present without power.
  • the relay 3 is actuated, so that all components of the household appliance 1 are disconnected from the mains.
  • a switching valve 4 is addressed, so that water can flow into a loop 5.
  • the ring line 5 is advantageously arranged in the interior of the household appliance that all combustible materials can be wetted by a generated spray.
  • the ring line 5 is designed as a non-combustible conduit and guided to all vulnerable components, which are provided at the critical points nozzles in the loop 5, can escape through the water or water mist.
  • a shut-off valve 8 which regulates the water supply to the household appliance, (in FIG. 2 dotted indicated) shut off.
  • aggregates such as pumps P, heaters or heat exchangers, etc., are arranged above the predetermined switching level so as to minimize any water damage.
  • a fire protection and fire extinguishing device for a water-conducting household appliance 1 which takes measures already at the beginning of a malfunction with potential fire sequence for the household appliance 1 measures to protect both the household appliance 1 from further damage, as well as a fire hazard and prevent to extinguish a fire that has arisen.
