Definitions

  • the present invention relates to suction cleaners and more particularly to a conversion arrangement therefore by which the cleaner may be used as an upright cleaner for on-thelioor cleaning or as a so-called canister type or general purpose cleaner by which all types of cleaning may be ⁇ done by means of a nozzle attached to the cleaner by a ilexible fand extensible hose. All of the parts necessary for the use of the cleaner for both types of operation are associated with the cleaner except the nozzles which are to be attached to the end of the hose.
  • the cleaner according to the present invention includes a chassis upon which a suction nozzle is pivoted for free floating operation when the cleaner is used as an upright cleaner for on-the-lloor cleaning operation.
  • a motor-fan-lter unit forms ⁇ a part of the handle and is also pivoted to the chassis on the same axis as the nozzle and also on the ⁇ axis of the motor-fan assembly.
  • the suction nozzle includes ra downwardly facing suction mouth, a suction passage extending rearwardly thereof at one end and a belt passage at the other end which is out of communication with the suction nozzle proper except for a passage for one end of a rotary agitator which is rotatably mounted within the suction mouth for contact with the surface being cleaned when the cleaner is being used as an upright cleaner.
  • the motor-fan assembly is provided with a belt pulley extending horizontally into .the belt passage in order ⁇ to drive the agitator by means of an endless belt surrounding the motor pulley and la pulley on the end of the agitator which extends into the belt passage. Since the nozzle and the motor-fan assembly are pivoted to the chassis on the same axis and on the axis of the motor-fan system the belt will remain taut in all pivoted positions of the nozzle and of the motor-fan-tlter mit when the cleaner is set for on-the-floor cleaning.
  • the motor-fan lter unit is enclosed within the casing and forms a portion of the propelling handle.
  • the suction inlet is in the top of the casing and a dirt collecting lter is supported within the casing ahead of the motorfan assembly so that the fan handles clean air.
  • a ilexible and extensible hose is attached at its upper end to the inlet tothe lter casing and its ⁇ lower end is detachably connected to the outlet from the suction passage of the suction nozzle.
  • the flexible hose When it is desired to use the cleaner for general purpose cleaning the flexible hose is detached from the suction nozzle outlet and the necessary cleaning tools including a wand attached to the hose at its free end.
  • the agitator be deactivated so that noharm will be done tothe surface upon which the cleaner rests by the rotation of the agitator with the cleaner standing still.
  • the agitator is deactivated when the cleaner is converted for general purpose cleaning by some means incident to the detachment of the lower end of the flexible hose from the suction nozzle outlet.
  • the nozzle is raised upwardly to deactivate the agitator.
  • the agitator is deolutched by loosening the belt when the hose is detached. Obviously the agitator could be declutched in other known ways to obtain the same result.
  • the act of removing the hose from the suction nozzle outlet activates a mechanism which deactivates the agitator.
  • a latch is usually provided for latching the lower end of the hose to the suction nozzle outlet. It is within the purview of the present invention to utilize the releasing movement of that latch for deactivating the agitator.
  • the agitator is deactivated by the closing of a closure for the outlet from the suction nozzle which operates when the hose is detached from that outlet.
  • Fig. 1 is a side view of a suction cleaner according to the present invention with the parts broken away to show the details of construction
  • Fig. 2 is a segmental view partly in section taken on line 2 2 of Fig. l and looking in ⁇ the direction of the arrows,

  • the motor may be electrically connected to a conventional electric cord in any suitable manner.
  • the motor For on-the-iioor cleaning the motor is energized and the cleaner propelled about over the carpet to be cleaned, the roller 44 holding the mouth 15 slightly above the carpet.
  • the suction produced by the fan will draw air into the nozzle mouth 15 and in so doing will raise the carpet upwardly against the nozzle mouth where it will be agitated by the rotating agitator 16.
  • the dirt removed by the combined action of the agitator and suction will be carried by the air stream through the suction nozzle, the outlet fitting 18, the hose 35 into the filter 30 where the dirt will be removed and the cleaned air will pass through the walls of the filter into the interior of casing 23.
  • the cleaned air will go through an opening 45 into the motor-fan chamber 46 and be drawn into the suction opening 47 of the fan chamber so as to be circulated through the motor to cool the same and be discharged to atmosphere from the upper end of the motor-fan casing as shown by the arrows in Fig. 3.
