Definitions

  • the invention relates to a Lucasabsaugsystem for a toilet having a toilet lid and a toilet seat, which are rotatably mounted about a common pivot axis.
  • Air extraction systems for toilets have long been known in various designs. They serve to counteract the sometimes extremely unpleasant odor when visiting a toilet.
  • the air extraction system draws air in the immediate vicinity of the toilet, which reduces the odor in a room where the toilet is located.
  • the air extraction system includes a suction channel, which also serves as a pivot bearing for the pivoting toilet seat.
  • the suction channel is made up of several juxtaposed segments which are rotatable about the pivot axis, wherein at least one seat segment is rotatably connected to the toilet seat.
  • One of the segments of the suction channel is rotatably connected to a toilet lid, so that the toilet lid pivotable about the Swivel axle is mounted. This latter segment, which is rotatably connected to the toilet lid, may be referred to as a lid segment.
  • the seat segment provides a connection between the provided with the air outlet openings toilet seat and the suction channel in terms of flow, so that through the seat segment, the sucked through the air outlet openings air can be removed.
  • the DE 691 174 00 T2 discloses a Lucasabsaugsystem for a toilet in which a suction duct as part of a piping system simultaneously represents a pivot bearing for the toilet seat and for a toilet lid.
  • a suction duct as part of a piping system simultaneously represents a pivot bearing for the toilet seat and for a toilet lid.
  • the suction of several, juxtaposed segments, two seat segments are rotatably connected to the toilet seat and a central, fixed segment between the two seat segments is arranged.
  • the central segment is connected to a discharge tube, while through the seat segments sucked through the toilet seat air can be removed via the central segment.
  • the invention is therefore an object of the invention to provide a Gutabsaugsystem for a toilet that can be easily mounted on conventional toilet bowls and eliminates unwanted odors on the toilet as efficiently as possible.
  • the air extraction system according to claim 1 is characterized in that the toilet lid comprises at least one air outlet opening, which is fluidly connected to the suction channel via the Dekkelsegment with which the toilet lid is rotatably connected. Air that passes through the at least one air outlet opening is preferably guided through a channel system in the toilet lid to the lid segment, so that then the extracted air enters the suction channel and then can be removed.
  • the at least one air outlet opening is arranged on an underside of the toilet lid.
  • the underside of the toilet lid In a closed state, the underside of the toilet lid is directed downwards and rests on an upper side of the toilet seat or faces the upper side of the toilet seat.
  • the toilet lid In an open position, the toilet lid is approximately perpendicular or has an acute angle to the vertical, wherein the underside of the toilet lid faces the toilet.
  • the toilet lid is in the open position approximately at right angles to the generally horizontally aligned toilet seat, as far as the latter rests on the toilet bowl.
  • the unwanted toilet odor can be sucked very efficiently.
  • the toilet exhaust gases escape due to their lower density upwards, which then largely flow through a gap between the opened toilet seat and the back of the person who is currently using the toilet.
  • a plurality of air vents on the underside of the toilet lid may be provided to allow a full-surface extraction.
  • the flow rates reduce the sucked air, so that excessive flow velocities, which are generally perceived as unpleasant, can be avoided.
  • the toilet seat has at least one air outlet opening, which is fluidically connected to the suction channel via the seat segment.
  • both the toilet seat and the toilet lid thus serve to suck the toilet odor.
  • the air outlet openings are arranged on an underside of the toilet seat. The underside of the toilet seat is spaced in a folded down position from an upper edge of the toilet bowl, so that an aspiration of the air through a gap between the upper edge of the toilet bowl and the bottom of the toilet seat is possible.
  • the suction channel can each have a plug connection for a suction hose at two front ends.
  • the suction hose can be mounted either at the one end face or the other front end, resulting in a great flexibility in the planning and installation of the Heilabsaugsystems.
  • the suction channel can be composed essentially of three segments, namely two seat segments and a lid segment, wherein the lid segment is arranged between the seat segments.
  • a seat segment has at one end facing away from the cover element on the plug connection for the suction hose.
  • the suction tube is rotatably connected about the pivot axis with the plug connection. This allows the suction hose remain in one position, even if by folding the toilet seat, the seat member with the plug connection rotates about the pivot axis of the toilet seat. As a result, the suction hose can be laid arbitrarily, without having to worry that the suction hose is twisted or braced when folding up or down the toilet seat.
  • the at least one seat segment and the at least one cover element may be arranged side by side in the longitudinal direction of the suction channel and connected to one another by a holder with a socket.
  • the holder with the socket on the one hand ensures that the seat segment and the cover element are rotatable relative to each other, and on the other hand ensures that an airtight or approximately airtight connection between the seat segment and cover element is formed so that air is not sucked in through the connection between the seat segment and cover element becomes.
  • the suction channel is fastened by the holder to the toilet bowl of the toilet.
  • this attachment of the holder takes place on the toilet bowl via a plate.
  • the plate is preferably designed so that they can cooperate with common toilet bowls, which have two spaced-apart holes on a back, in a simple manner for the purpose of attachment.
  • At least one upper air vent opening spaced at least 80 cm from the pivot axis of the toilet seat and toilet lid at least 80 cm, assuming that the pivot axis extends in the horizontal direction.
  • the upper air outlet opening 100 to 200 cm, preferably 120 to 160 cm above the pivot axis to arrange.
  • the upper air outlet opening is preferably located above the toilet lid in the open position, ie without lateral offset.
  • the part of the exhaust gases can be removed, which is pasted unsabsorbed on the underside of the toilet lid.
  • the exhaust gases can be sucked through the upper air exhaust opening, which accumulate in an upper area of the room in which the toilet is located. It has been found that the upper air outlet opening in conjunction with the toilet seat provided with a plurality of air outlet openings and with the toilet cover provided with a plurality of air outlet openings leads to excellent results.
  • a suction unit of the air extraction system according to the invention can be provided in the suction direction behind the upper air outlet opening.
  • a switching device which controls the suction unit, wherein the switching device comprises a timer and / or a motion detector. Also, the switching device may include a sensor that is incorporated in the toilet seat and emits a signal when the toilet seat is applied with a certain weight. The switching device may also be connected to a light switch so that the suction unit is turned on when the light switch is operated.
  • the switching device controls by air or throttle valves, the ratio of the amounts of air that are sucked through the air outlet openings of the toilet seat, through the air outlet openings of the toilet lid and through the upper air outlet opening.
  • a different ratio can be set than in the time after use of the toilet, provided that the suction unit runs after a certain period of time after using the toilet.
  • the suction unit and the upper air vent are located no more than 30 cm, ideally not more than 20 cm apart. This opens up the possibility of decorating suction unit, for example, in the form of a centrifugal fan and the upper air outlet opening by a light decorative.
