Definitions

  • My invention relates to vacuum cleaners and particularly to a resilient mounting for the motor of a vacuum cleaner and an air sealing arrangement for the incoming and outgoing sides of the motor and fan unit.
  • My invention has particular usefulness in vacuum cleaners of the so-called tank type.
  • the objects of my present invention are obtained by mounting the motor and fan unit at its ends between two rings of resilient material within the casing of the cleaner, the resilient rings supporting the unit out of contact with the cleaner casing and providing a sealed space between the unit and the casing.
  • Fig. l is a longitudinal cross section through a tank type vacuum cleaner showing parts broken away to illustrate my invention
  • Fig. 2 is a perspective view of one of the motor mounting and sealing members.
  • a cleaner according to my invention may have the usual hollow body or casing l of generally cylindrical form, having the usual handle 2 and runners or skids 3 which are suitably secured to the body. With the exception of the mounting for the motor and fan unit, the inner parts of the vacuum cleaner may be more or less conventional.
  • an inlet end cap i On the inlet or suction end of the cleaner body is shown an inlet end cap i with a central opening 5 and a latch controlled by a pushbutton catch 6 for removabl securing the end cap to the body proper. Any other suitable manner of removably securing the cap to the body of course may be used.
  • a dust filter or bag I is suitably secured within the cleaner immediately inside the inlet end of the body and occupies the major portion of the interior of the inlet side of the cleaner in the usual fashion.
  • a motor and fan unit indicated by the number 8 in the drawing. This is spoken of sometimes as the motor unit and sometimes as the motor-fan unit because in effeet the motor and fan are contained together within a single housing and the fan may be located at either end of the housing as desired.
  • the outside or housing of the motor unit i imperforate at its sides although it is open at its ends.
  • the open inlet end of the unit is surrounded by an annular flange 9 which extends axially of the cleaner from the inlet end of the unit housing.
  • the outlet end of the unit has an open end defined by the axially extending annular flange 50.
  • the inlet end of the motor-fan unit is secured and supported within the cleaner casing by means of a transverse partition H which is welded or otherwise firmly secured in air tight relation within the casing at its circumferential flange 12.
  • This partition has a central circular opening l3 surrounded by a sloping section l i which as shown has a slope extending in the direction of the motor unit.
  • a bag supporting screen l5 may be suitably carried by the partition H and secured over the central opening E3 in order to prevent the dust filter or bag from collapsing against the opening and blocking it when the cleaner is in operation.
  • the motor unit is supported through the medium of the partition ll, it is not directly supported thereby nor does the unit touch the inside of the cleaner casing or body at any point.
  • the motor unit is separated from the transverse partition and from the inner Walls of the cleaner casing by means of the resilient supporting member it, preferably made of solid live rubber.
  • This member has an inner circular opening 5'! of a size to fit snugly around the flange 9 which form the inlet to the motor unit.
  • Surrounding the central opening H is an annular section ii!
  • the face of the resilient supporting member II; which is opposite the partition outside of the central opening is provided with a sloping frustoconical surface 20 corresponding to and fitting closely against the sloping surface [4 on the partition.
  • the other face of the supporting member fits flat and snug against an opposing wall on the motor unit housing. This interfitting of the tapered surfaces adds a frictional fit between the parts and further aids in the support of the motor unit within the body.
  • Immediately surrounding the tapered section 20 of the supporting member is another annular section 2
  • each of the legs is provided with an enlarged head or tip portion 24 which is of approximately the same axial thickness as the annular portions [8 and 2
  • the enlarged end portions 24 may be regarded as resilient supporting blocks which are held in spaced relation from each other and from the central supporting ring sections by means of the thin sections or legs 23. Being under compression, they efiectively prevent shifting or weaving of the motor fan unit in the casing and damp vibration which might otherwise be transmitted to the casing.
  • an outlet end cap 25 with the usual central discharge opening or port 26 formed by the axially extending discharge tube 21 which is positioned inside of the annular flange l forming the air outlet of the motor and fan unit.
  • a tube similar to the tube 21 may be provided for the air inlet opening 5 in the inlet end cap at the other end of the cleaner.
  • the oute 0 sc e tube 21 serves an added function in the outlet end cap as will be clear later.
  • the end cap 25 is suitably secured to the body of the cleaner and I have shown for this purpose a hook member 28 secured to the end cap and engaging a slot 29 which is provided on an interior annular flange 30 which in turn is secured to the body or main portion of the casing of the cleaner.
  • the flange 30 properly positions the end cap on the end of the cleaner casing and the hook will hold the top side of the cap in place.
  • the outlet flange ID on the unit housing is provided at its base with an inwardly projecting rib or shoulder 32. Seated on this shoulder within the unit housing is a bearing disk or washer 33. This washer forms a ledge within the end of the motor housing and on this ledge is seated a second resilient mounting ring of solid live rubber or other suitable material 54. A central opening 35 in this ring closely surrounds the discharge port tube 21 of the end cap. The outside of this resilient ring fits closely within the annular flange ID of the motor fan unit housing and against the ledge formed by washer 33.
  • This supporting ring is made sufficient to prevent contact between the motor unit housing and the inside of the end cap even when the resilient ring is compressed to its fullest extent between the washer and the end cap.
  • An annular groove 36 may be provided in one face of the supporting ring 34 further to dampen vibration which might be transmitted and to allow a certain amount of give and take to compensate for manufacturing variations in the dimensions of the parts. The outlet end of the motor and fan unit will thus be supported in radial shear within the body of the cleaner as well as in axial compression when the end cap is secured in place,
  • a dead air space 31 is provided between the cleaner casing and the outside of the motor and fan housing.
  • a suitable control switch 38 for the motor having a handle or button 39 extending outside of the cleaner casing.
  • Power to operate the motor is obtained through a suitable cord set 46 connected by a plug 4
  • the cord 40 passes through a wall of the body of the cleaner into the dead air space 3'! and is connected through the switch 38 to the motor in the motor section of the motor and fan unit.
  • the connection wires between the switch and the motor are shown at 42.
  • a vacuum cleaner of the type having a hollow body with an opening at the end, a partition transverse of the body spaced from said end, a central opening in the partition, a motor-fan unit inside the body between the partition and the end, said unit having a central inlet opening in a wall thereof facing said opening in the partition, a sealing and supporting structure for said motor-fan unit comprising an axially extending annular flange surrounding said central inlet opening on said motor-fan unit, said flange being spaced radially inwardly of the edges of said opening in said partition, an annular resilient live rubber member extending radially between said flange and said partition opening, a plurality of spaced radially extending legs integral with said annular resilient member positioned between but spaced from said partition and said motor-fan unit, an enlarged portion on the outer end of each leg positioned be tween said partition and said unit, said enlargements each terminating short of said body, and an annular resilient member supporting the opposite end of said motor-fan unit from
  • a vacuum cleaner having a hollow cylindrical body with an open end, an end cap removably closing said end, said end cap having a central exhaust opening therein, an inwardly and axially extending tube on said end cap surrounding said opening, a wall in said body extending transversely thereof and spaced from said end, said wall having a central opening therein, a motorfan unit suspended in the space between the wall and the end cap, said unit having a central inlet opening in an end wall thereof facing said opening in the wall, an axially extending annular flange surrounding said central inlet and spaced radially inwardly of the edges of the wall opening, said unit having a central flanged outlet opening in the opposite end thereof spaced radially outwardly of the edges of the tube on the end cap, a resilient body with a central annular portion surrounding the inlet flange on said unit and extending in supporting relation between said flange and the opening in the wall, radial extensions on said annular portion ending at their tips in resilient supporting blocks positioned between said wall and
