Vacuum Cleaner

Abstract

The present invention is directed to a vacuum cleaner ( 1 ) comprising a horizontal type cleaner body ( 2 ) with a bottom ( 3 ), top ( 4 ), front ( 5 ) and back side ( 6 ), a suction blower unit accommodated in the cleaner body ( 2 ) and at least one primary stage cyclone dust separator ( 7 ) having an air inlet opening fluidly coupled to the suction blower unit, wherein in bottom to top direction the primary stage cyclone dust separator ( 7 ) is positioned over the suction blower unit, and wherein the air inlet opening and a dust outlet opening of the primary stage cyclone dust separator ( 7 ) are located towards the back side ( 6 ) and front side ( 5 ) respectively.

1 . A vacuum cleaner comprising:
 a horizontal type cleaner body having a bottom side, a top side, a front side, a back side, and a suction blower unit accommodated in the cleaner body; and   at least one primary stage cyclone dust separator having an air inlet opening and a dust outlet opening, wherein the air inlet opening is fluidly coupled to the suction blower unit,   wherein in the bottom side to top side direction, the at least one primary stage cyclone dust separator is positioned over the suction blower unit, and   wherein the air inlet opening and the dust outlet opening of each of the at least one primary stage cyclone dust separator are located towards the back side and front side, respectively.   
     
     
         2 . A vacuum cleaner according to  claim 1 , wherein the suction blower unit comprises a fan coupled to a fan drive motor, wherein, in the front side to back side direction, the fan drive motor is positioned offset and behind the fan. 
     
     
         3 . A vacuum cleaner according to  claim 2 , wherein, in the front side to back side direction, the air inlet opening of each of the at least one primary stage cyclone dust separator is offset and arranged behind the fan. 
     
     
         4 . A vacuum cleaner according to  claim 3 , wherein an air outlet of the fan and the air inlet opening of each of the at least one primary stage cyclone dust separator are fluidly connected to an intermediate air chamber. 
     
     
         5 . A vacuum cleaner according to  claim 1 , wherein the dust outlet of each of the at least one primary stage cyclone dust separator is fluidly connected to a dust collecting chamber arranged at the front side. 
     
     
         6 . A vacuum cleaner according to  claim 5 , wherein the dust collecting chamber is removably connected to at least one of the set consisting of the at least one primary stage cyclone dust separator and the cleaner body. 
     
     
         7 . A vacuum cleaner according to  claim 5 , wherein the dust collecting chamber comprises a fill level indicator at the front side. 
     
     
         8 . A vacuum cleaner according to  claim 5 , wherein the at least one primary stage cyclone dust separator is implemented and installed such that in intended use operation, a main air flow through the at least one primary stage cyclone dust separator is oriented essentially parallel to the front side to back side direction. 
     
     
         9 . A vacuum cleaner according to  claim 5 , wherein with regard to the top side to bottom side direction, a dust collecting volume of the dust collecting chamber is at least partially arranged below the dust outlet opening of each of the at least one primary stage cyclone dust separator. 
     
     
         10 . A vacuum cleaner according to  claim 5 , wherein an angle of inclination between a main air flow direction through the at least one primary stage cyclone dust separator and a center axis of the dust collecting chamber lies in a range between 40 and 80 degrees. 
     
     
         11 . A vacuum cleaner according to  claim 10 , wherein the angle of inclination is about 60 degrees. 
     
     
         12 . A vacuum cleaner according to  claim 5 , wherein at least one of the set consisting of the at least one primary stage cyclone dust separator and the dust collecting chamber are centered about a back side to front side vertical center plane of the cleaner body. 
     
     
         13 . A vacuum cleaner according to  claim 1 , further comprising at least one secondary stage cyclone dust separator installed downstream of the at least one primary stage cyclone dust separator. 
     
     
         14 . A vacuum cleaner according to  claim 7 , wherein the fill level indicator comprises a fill level inspection window. 
     
     
         15 . A vacuum cleaner according to  claim 4 , wherein the intermediate air chamber at least partially encompasses the fan drive motor.
