Definitions

  • the invention concerns a plastic housing for holding an electric or electronic circuit in an appliance in a fire resistant manner.
  • the electronic frequency converter system of a washing machine is disposed in a housing which is entirely formed of a plastic material of a fire-resistant nature, that is to say of a fire-resistant plastic material.
  • a fire-resistant plastic material is complicated and expensive to produce and is limited in terms of processing thereof.
  • a plastic housing for an electric or electronic circuit to be disposed in an electrical or electronic appliance.
  • the plastic housing contains at least two housing elements releasably connected together and include a first housing element formed of a fire-resistant plastic material and a second housing element formed of a non-fire-resistant plastic material.
  • the housing elements hold the electric or electronic circuit in a fire-resistant fashion.
  • a core concept of the invention provides that it is no longer the entire housing that is formed of the fire-resistant plastic material, but only that part of the housing which holds the electric or electronic circuit.
  • the housing contains at least two housing elements which are releasably connected to each other.
  • the first housing element is made from a fire-resistant plastic material while the second housing element contains a conventional, non-fire-resistant plastic material.
  • a suitable plastic material with fire-resistant properties is preferably PPE+S/B X or PC-ABS-FR while a suitable material for a conventional plastic material is preferably PPTV20.
  • the second housing element which is formed of the non-fire-resistant plastic material has a flap which is connected by a film hinge to the remaining part of the housing element.
  • a film hinge could not be implemented at all or it could not be implemented at justifiable cost or with a justifiable degree of complication and expenditure.
  • the flap can protect one or more connecting sockets or plugs of the electric or electronic circuit.
  • a flap which is formed on the second housing element by a film hinge can alternatively also be releasably connected to the first housing element in such a way that the second housing element can be pivoted open by way of the film hinge and thus the housing can be opened and also closed again.
  • the electric or electronic circuit is preferably fixed within the housing to the first housing element formed of the fire-resistant plastic material.
  • the fixing is effected by a fixing element containing a fire-resistant plastic material.
  • the fixing element used is a fixing frame formed of PA66GF35FR.
  • the fixing element may in addition also have a guide device and a coding device for the connecting sockets or plugs of the electric or electronic circuit.
  • the guide device is preferably of such a configuration that at the same time it has the coding device.
  • the housing is further configured so that the electric or electronic circuit is protected therein from splash or spray water.
  • the electric or electronic circuit is preferably formed by a power circuit, in particular by an electronic frequency converter configuration for a drive motor of a washing machine, a laundry drier or a washer-drier (washing machine-laundry drier combination).
  • FIG. 1 is a diagrammatic, exploded perspective view from the side of a front of a plastic housing for an electronic frequency converter configuration for a washing machine according to the invention.
  • FIG. 2 is an exploded, perspective view of the plastic housing of FIG. 1 from the side of the rear.
  • FIG. 1 there is shown a plastic housing for a washing machine electronic frequency converter configuration.
  • the housing contains two housing elements 1 , 2 .
  • a first housing element 1 in the form of a rear portion is formed of a plastic material PPE+S/B X (of a fire-resistant nature), and a second housing element 2 in the form of a front portion is formed of a non-fire-resistant plastic material PPTV20.
  • support feet 4 Formed on an underside 3 of the rear portion 1 are four support feet 4 , while formed at an underside thereof there are in turn fixing elements 5 of a cross-section in the form of an inverted T. With the fixing elements 5 , the support feet 4 can engage through corresponding slots in a support or bottom panel of a washing machine or can engage behind the support or bottom panel, thereby providing for secure fixing of the plastic housing in the washing machine.
  • a fixing frame formed of the fire-resistant plastic material PA66GF35FR (not shown in the figures) is then put on to the front side of the circuit board.
  • the fixing frame is retained by undercut configurations of fixing hooks 7 formed on the rear portion 1 and by snap hooks 8 which are disposed in opposite relationship to the fixing hooks 7 and which are also shaped on the rear portion 1 so that this affords a stable mount for the circuit board carrying the electronic frequency converter configuration.
  • the circuit board with the electronic frequency converter configuration can also be fixed to the fixing frame by the snap hooks, screws or the like prior to insertion into the rear portion 1 , and can then be fitted together with the fixing frame into the rear portion 1 .
  • the fixing frame can be of such a configuration that it itself (and not the circuit board) bears against the abutments 6 .
  • the rear portion 1 further has openings 9 , 10 through which connecting sockets on the circuit board are accessible.
  • the connecting sockets can be mounted directly on the circuit board. They can however also be formed by guide elements which are formed on the fixing frame and which at the same time also have a plug coding device, together with contact strips disposed on the circuit board.
  • the front portion 2 of the housing has a plurality of ventilation slots 11 through which cooling air can pass into the interior of the housing.
  • a protective flap 13 Formed on one side of the front portion 2 by a film hinge 12 is a protective flap 13 which, in the assembled condition of the housing, can be pivoted in such a way that it can be latched in front of the openings 9 and 10 in order to prevent the ingress of splash or spray water through those openings 9 and 10 into the interior of the housing and in particular on to the electronic frequency converter system.
  • the configuration ensures that, even when the protective flap 13 is closed, a slot still remains open for the passage therethrough of cables connected to the connecting sockets disposed on the circuit board.
  • a fixing flap 15 is also formed on the upper end of the front portion 2 by way of a film hinge 14 .
  • the flap 15 can be pivoted around the top side of the rear portion 1 , in which case snap hooks 16 formed on the top side of the rear portion 1 engage through openings 17 in the fixing flap 15 of the front portion 2 and snap into engagement there.
  • the front portion 2 is fixed to the rear portion 1 by way of the fixing flap 15 .
  • a main body 18 of the front portion 2 can now be pivoted around the film hinge 14 between the fixing flap 15 and the main body 18 so that the housing can be opened and closed by pivoting the main body 18 of the front portion 2 open and shut.
  • a screw dome 23 which is formed laterally on the rear portion 1 and which has a screw guide sleeve 24 serves for fixing the entire housing to the domestic appliance.
  • cooling air enters at the side of the housing which is lower and issues again at the side of the housing which is higher (at the hose holding arm 25 ) and in so doing increasingly sucks in cooling air through the lower cooling openings 11 .
  • the effect is further increased by an air baffle wall 27 provided at the inside of the front portion 2 .
  • a fixing extension 28 Disposed in the rear portion 1 or in a fixing extension 28 formed thereon are holes 29 into which cable holding ties or tie holders for cable holding ties or also clips can be snappingly fitted. In that way, together with a cable guide 30 which is also formed on the fixing extension 28 , cables or cable harnesses which are disposed within the electrical or electronic appliance are firmly fixed to the housing, whereby it is possible to prevent the cables from being chafed through.
