Definitions

  • the invention relates to a dishwasher, the a washing container in which liquid for cleaning is circulated by dishes, with a drain pump, the an inlet adjacent the bottom of the wash tank has, and with a drain line, through the liquid is drained from the wash tank.
  • U1 is a dishwasher with a sewage pump known.
  • a Drain pipe connected to a vertical, U-shaped bent pipe section with a pipe vent valve having.
  • the drain line with the pipe vent valve is integrated in a flat device unit, which is between a Side wall of the washing container and a housing of the dishwasher is arranged.
  • the pipe vent valve includes a float Valve body with a closing body. This is in the gasket layer on a contact surface of a partition between the branch and the venting channel.
  • the valve body itself is as open in the flow direction cylinder formed with a conically converging tip. there the closing body is attached to the tip of the valve body.
  • a conical mandrel is provided, slipped over a serving as a closing body membrane is. The membrane is placed in a groove between the Mandrel and the tip of the valve body held. In this dishwasher thus becomes a multiplicity of different Components required for the sealing of the ventilation channel, which must be precisely matched to each other and therefore significant Cause costs.
  • EP 0 382 692 B1 describes a dishwasher apparatus, which comprises a washing container, in the liquid is circulated for cleaning dishes.
  • a washing container in the liquid is circulated for cleaning dishes.
  • One in the Wash tank provided drain pump has an inlet on, which is mounted near the bottom of the wash tank is.
  • a drain line connected, which at its highest point a constriction has, in turn, connected to the wash tank is, so when emptying the wash tank in the connection a vacuum is created by the air from the wash tank is sucked.
  • this object is achieved in a dishwasher of the type mentioned solved in that to the Outflow line up a sealing and down ventilated Ventilation valve with a sealing seal and a arranged float consisting of a single component is.
  • the inventively designed drain line at a dishwasher where the drainpipe a pipe ventilation is needed whenever and whenever the connection point of the drainpipe at the same height or below the device footprint, to prevent that the dishwasher is completely idle or that it is in washing programs with partial emptying to malfunction comes.
  • the ventilation valve is in one standard deflation hose system used in a dishwasher integrated.
  • the ventilation valve especially at the highest point in the drainage line, at a branch is arranged to a vent channel.
  • an elbow is attached.
  • the vent valve in an insertable into the elbow plug or in one fixed to the elbow Integrated connection piece.
  • the elbow with a branching Ventilation nozzle is in the drain hose additionally introduced or is between the sewage pump and arranged the drain hose.
  • An advantage is a dishwasher, where the vent valve at a branch included in the drainage line contained in a plug-in or connected to this is.
  • venting channel directly or indirectly above one above the highest level of liquid in inlet attached to the water tank connected thereto is.
  • the venting channel is omitted, and The ventilation valve opens into the open.
  • the inventively provided float is advantageous as Ball or designed as a flap.
  • the drain pipe at least partially convex downward bent or the shape of an inverted U Has.
  • the drainage hose system is integrated through the directly integrated Pipe ventilation system hardly due to flow losses and dead spaces impaired.
  • the system behaves uncritically against deposits such as fats and not soluble leftovers.
  • a dishwasher comprises a washing container 1 (Fig. 1), in which a (not shown) front, during operation through a hinged lid bring the closed opening to be cleaned dishes leaves.
  • the washing container 1 comprises one opposite the other Tank volume recessed floor area 2, in which always Water can be left behind.
  • Inlet or intake 3 of a side of the washing tank 1 arranged sewage pump 4 into, after completion a rinse and in particular after the last rinse the water contained in the wash tank sucks and pumped into a drain line 5.
  • the drain line 5 is preferably convex or semicircular bent downwards.
  • Preferably at its highest Point has an up-sealing and down-venting in a connecting piece 6 integrated vent valve on.
  • a connecting piece 6 integrated vent valve on.
  • At the connecting piece 6 closes after above a vent channel 7, which at its upper end above of the highest achievable in the washing tank 1 Liquid level with an opening 8 in the washing container. 1 is connected via a connecting pipe 9.
  • a corrugated pipe 10th (Fig. 2) suitable, via a connecting piece 11 in a Angle element 12 is inserted. This is in turn with the Sewage pump 4 connected.
  • a connecting element 14 Integrated in the corrugated tube 10 an opening 13 having a connecting element 14 as a receptacle for a vent valve 15 ( Figure 3).
  • the vent valve 15 is in an opening 13 surrounding Collar 16 with a connection part or a Einstecktülle 17 inserted. Inside contains the ventilation valve 15 a ball 18. This is usually on (not here shown) holding areas in the interior of the ventilation valve 15 on such that laterally of the holding areas and the Ball 18 can flow air to ventilate the corrugated pipe 10.
  • FIG. 4 In another embodiment of the invention (FIG. 4) is a Angle element 20 with a connection 21 for the sewage pump 4 and a further connection 22 for the sewage or discharge hose 5, in particular the corrugated pipe 10, provided.
  • a connecting piece 23 Integrated into the angle element 20 is a connecting piece 23, which is formed so that on a shoulder 24 a Ball 25 rests without an air flow to the side of the ball 25 and past the shoulder 24 over.
  • the ball 25 by from below against oppressive liquid against a spherical cap-shaped collar 26 in one Connector 27 is pressed so that this up against the escape of the liquid is sealed.
  • the fitting 27 is either open at the top or like that Ventilation valve 15 connected to a vent channel 7, preferably via a connecting pipe 9 to the water tank 1 is connected.
