Definitions

  • the present invention relates to a cleaning machine, particularly for domestic use, such as a vacuum cleaner or a steam-cleaning machine.
  • One known cleaning machine comprises a casing that takes a tank designed to contain and/or collect a liquid and connected in one direction to a suction hose and in the other direction to a suction means powered by an electric motor, both the suction means and the motor also being housed inside the casing.
  • the liquid in the tank is traversed by a stream of air drawn in from a surface that is being cleaned, through the suction hose, and the dust is trapped in the liquid, which is usually water or an aqueous solution containing cleaning products, air fresheners, etc. Having been cleaned of its dust, the air passes out of the tank and is returned to the surrounding environment via suitable apertures in the machine casing.
  • the tank In one known type of machine the tank is simply placed in its seat in the machine casing and is closed at the top by a lid, hinged to the machine casing, and fastened to the lid by snap action.
  • the tank is fitted with a flexible handle which can be grasped to remove the tank and then relocate it in the seat of the machine casing after the dirty water has been replaced with clean water.
  • a cleaning machine comprising a casing having a seat that takes a removable tank for a liquid necessary for the operating circuit of the machine, characterized in that the said tank is fitted with a handle able to be moved between a handle rest position in which the handle engages with a fixed portion of the machine casing to lock the tank in the seat of the machine casing, and a handle-grasping operating position in which the handle is disengaged from the said fixed portion of the machine casing to remove the tank from the casing.
  • the machine illustrated which is given the general reference 1, comprises a casing 2 fitted with wheels 3 for moving the machine about. It also has a handle 4 for carrying the machine.
  • a connecting and filtration unit 8 At the top of the tank 6 is an opening 7 allowing the insertion of a connecting and filtration unit 8, of which the bottom part is shown in Fig. 1 and the top part in Fig. 2.
  • the tank 6 with the connecting and filtration unit 8 is closed above by a removable lid 9.
  • the lid 9 has a socket 10 to which a suction hose (not shown) is connected.
  • the tank 6 When cleaning, the tank 6 is filled with water and the suction pump is started by the electric motor. Via its open end, the suction hose connected to the socket 10 is placed on the surface to be cleaned. The air mixed with suspended dust is drawn into the tank 6 through the hose, the socket 10 and a pipe 11 forming part of the connecting and filtration unit 8. Inside the tank 6 the air mixed with the suspended dust is subjected to a sort of washing and the dust is left in the water inside the tank. The clean air passes out of the tank 6 through a filter in the connecting and filtration unit 8 and through pipes 12 formed within the tank 6, after which the clean air passes through pipes 26 in the seat 5 and on to the pump which returns it to the exterior through suitable apertures at the back of the machine casing 2.
  • the socket 10 on the lid 9 is in airtight connection with the connecting and filtration unit 8, but separated from it when the lid is removed.
  • the pipes 12 inside the tank 6 are in leaktight connection with the pipes 26 in the seat 5, but separated from them when the tank is removed from the seat.
  • the tank 6 is fitted with an arched handle 13.
  • Each extension 14 is shaped in its terminal portion in such a way as to form on the same axis a cylindrical through seat 15 and a C-shaped seat 16.
  • the cylindrical seat 15 of each extension 14 takes a respective pin 17 integral with the casing of the tank 6, so that the handle 13 can rotate relative to the tank casing.
  • Each extension 14 also comprises an arm 18 designed to abut against a transverse wall of a respective L-shaped shoulder 19 integral with the casing of the tank 6, in order to limit the rotation of the handle 13.
  • the lid 9 is hinged to the machine casing 2 detachably by means of two angular tabs 21 that engage in two slots 22 in the machine casing.
  • the lid 9 engages with a snap action in a catch 23 on the top of the tank 6, a button 24 being provided on the lid to allow it to be opened.
  • the tank 6 When the cleaning machine 1 is assembled and ready to operate, the tank 6 is inserted in the seat 5 and the handle 13 of the tank is laid horizontally in a corresponding recess 25 of the tank so that it does not project beyond the tank profile.
  • the handle 13 When the handle 13 is laid in this position, the C-shaped seats 16 of the extensions 14 of the handle fit around the pins 20 of the machine casing 2, thus preventing the tank 6 from coming out of the seat 5, as Fig. 2 makes clear.
  • the lid 9 is mounted on top of the tank 6 using its tabs 21 inserted in the slots 22 in the machine casing 2 and fastened to the catch 23 of the tank 6.
  • the working configuration of the machine is illustrated in Fig. 3.
  • the lid 9 is first taken off by disconnecting it from the catch 23 by pressing on the button 24, rotating it upwards about the hinges formed by the tabs 21 and by the slots 22, and lifting it out of the machine casing 2 due to the fact that it is possible to pull the tabs out of the slots when rotated in its upward position.
  • the handle 13 of the tank 6 is raised to the vertical position and in this position the C-shaped seats 16 of the extensions 14 of the handle have been rotated so that they disengage when moved in the direction in which the tank is lifted out of the seat 5 of the machine casing 2.
  • the arms 18 of the extensions 14 of the handle 13 prevent the handle from rotating too far beyond its vertical position because they abut against the shoulders 19 of the casing of the tank 6 when the handle exceeds this vertical position by more than a small angle.
  • the configuration of the cleaning machine and of its components may differ from that illustrated.
  • the tank and its handle may be configured differently.
  • the handle may engage in any way with the machine casing to lock the tank to the machine casing when the said handle is in the rest position and to release it when the handle is in the grasping position for removal of the tank.
  • the handle may engage in any way with the machine casing to lock the tank to the machine casing when the said handle is in the rest position and to release it when the handle is in the grasping position for removal of the tank.
  • the handle may engage in any way with the machine casing to lock the tank to the machine casing when the said handle is in the rest position and to release it when the handle is in the grasping position for removal of the tank.
  • a system equivalent to that seen in the example or a system of snap engagement of the handle to the machine casing, and so on is to use a system equivalent to that seen in the example or a system of snap engagement of the handle to the machine casing, and so on.
  • the above account can also be applied to any type of cleaning machine that uses a removable tank, such as a steam-cleaning machine.
