Definitions

  • the invention relates to a handpiece for a steam cleaning device with an introduction of a steam supply line leading from a steam generator to the handpiece, a steam discharge line and with an electrical switch for switching the steam supply from the steam generator to the handpiece on and off.
  • a handle is movably mounted in the handpiece and can be moved against the action of a spring into a working position in which the switch is actuated by the handle and the steam supply is switched on, and which is in a rest position with the spring relaxed, in which the switch is not actuated and the steam supply is switched off.
  • steam can only be supplied by the steam generator and released via the handpiece if the user moves the handle against the action of the spring. If the user lets go of the handle, it is inevitably moved under the action of the spring into the rest position, in which the steam supply to the handpiece is interrupted. This applies in particular if the user unintentionally drops the handpiece.
  • a latch is slidably mounted on the handpiece and can be moved between a position that fixes the handle in the rest position and a position that releases the handle.
  • the handle can only be moved against the action of the spring and the steam supply can thus be switched on when the latch is moved into the position releasing the handle is, that is, the user must move this bar deliberately in the release position in order to allow a steam supply at all.
  • a latch acts as an additional safety measure, for example as a child lock.
  • the handling of the handpiece is improved if the handle is arranged on the underside of the handpiece.
  • the handle is a swivel lever.
  • the handle is a wall area of a housing forming the handpiece, which closes an opening on the underside of the housing.
  • the housing thus has a window-like opening on its underside, into which the wall area which forms the handle is fitted.
  • the wall area can be pivotally mounted on the housing so that the handle is normally inevitably actuated when the handpiece is gripped. It is therefore not necessary for the user to grasp the handpiece in a very special way or even to grip it to actuate the steam supply, but rather the handgrip is automatically actuated when the handpiece is gripped normally.
  • the handle carries a switching projection which is opposite a switching lug of a microswitch fixed in the handpiece.
  • the spring is a helical spring that dips into a pot-shaped recess in the handle and is supported on a contact surface of the handpiece.
  • the handpiece 1 shown in the drawing comprises two tubular sections 2, 3, which form an angle of approximately 150 ° between them.
  • the handpiece 1 is enclosed by a housing which is composed of two half-shells or housing halves which are separated from one another along the longitudinal center plane of the handpiece 1 and which are essentially mirror images.
  • a steam feed line 4 opens into the handpiece 1, which connects the handpiece 1 to a steam generator (not shown in the drawing).
  • This steam supply line 4 leads to a metering valve 5 in the front section 2 of the handpiece 1, which is only dashed in the drawing is indicated.
  • a steam discharge line 6 connects to the metering valve 5, through which steam supplied by the steam generator can be discharged.
  • a microswitch 7 with a sliding switching lug 8 is arranged, this microswitch 7 is also connected to the steam generator via electrical lines, not shown in the drawing.
  • the microswitch switches on the steam supply in the actuated state, that is to say when the switching lug 8 is pressed in, and cuts it off in the unactuated state.
  • the housing On the underside of the handpiece 1, the housing has a window-shaped opening 9 in the area of the rear section 3, which is closed by a handle 10 that completely fills this opening 9.
  • the handle 10 is pivotally mounted on the handpiece 1 about an axis of rotation 12 extending transversely to the longitudinal axis of the rear section 3, the axis of rotation being located at the rear end of the opening 9 Wall area 11, the other end of the coil spring 12 is supported on a contact surface 14 which is part of the handpiece 1.
  • the wall area 11 is pivoted outwards from the inside of the handpiece 1 until a stop 15 at the free end of the wall area 11 comes to rest on a projection 16 in the front section 2 of the handpiece 1. In this position, the wall area 11 is aligned with the rest of the housing and thus closes the opening 9 as part of the housing.
  • the wall area 11 can be pivoted into the opening 9, as shown in broken lines in FIG.
  • the handle 10 In the interior of the handpiece 1, the handle 10 carries a switching projection 17 which is directly opposite the switching lug 8 of the microswitch 7. If the handle 10 is pivoted outwards under the action of the coil spring 12, it is in a rest position in which the switching projection 17 is lifted off the switching lug 8 of the microswitch 7, the switching lug 8 is then not pressed in. If the handle 10 is pivoted in against the action of the coil spring 12, it comes into a working position. The switching projection 17 rests on the switching lug 8 and presses it into the microswitch 7, the microswitch 7 is thus actuated thereby.
  • a slide 18 is slidably mounted, which in an end position engages behind the handle 10 with a projection 19 when it is in the rest position.
  • the handle 10 is fixed in this rest position, and even pressure on the wall area 11 then does not result in the wall area 11 pivoting into the interior of the Handpiece 1.
  • the steam supply cannot be switched on, it is first necessary to move the slide 18 into a release position in which the projection 19 no longer engages behind the wall area 11 (as shown in FIG. 1).
