Vacuum cleaner with wand activated conversion valve

Abstract

A floor care apparatus includes a housing having a nozzle assembly and a canister assembly. A suction inlet is provided on the nozzle assembly. A dirt collection vessel, a suction generator and a wand receiver are carried on the housing. A first air flow pathway connects the suction inlet to the dirt collection vessel and the suction generator. An air flow control valve includes a valve body received in the first air flow pathway and an actuator having at least a portion thereof extending into the wand receiver. A cleaning wand assembly is displaceable between a first storage position wherein a first end of the cleaning wand assembly is held in the wand receiver engaging the actuator and opening the valve and a second position wherein the cleaning wand assembly is withdrawn from the wand receiver for cleaning with the cleaning wand assembly thereby disengaging the actuator and closing the valve. A second air flow pathway connects the cleaning wand assembly to the first air flow pathway between the valve body and the dirt collection vessel.

1 . A floor care apparatus comprising:
 a housing including a nozzle assembly including a suction inlet and a canister assembly connected to said nozzle assembly;   a dirt collection vessel carried on said housing;   a suction generator carried on said housing;   a first air flow pathway connecting said suction inlet to said dirt collection vessel and said suction generator;   a wand receiver carried on said housing;   an air flow control valve having a valve body received in said first air flow pathway and an actuator having at least a portion thereof extending into said wand receiver;   a cleaning wand assembly displaceable between a first storage position wherein a first end of said cleaning wand assembly is held in said wand receiver engaging said actuator and opening said valve and a second position wherein said cleaning wand assembly is withdrawn from said wand receiver for cleaning with said cleaning wand assembly thereby disengaging said actuator and closing said valve; and   a second air flow pathway connecting said cleaning wand assembly to said first air flow pathway between said valve body and said dirt collection vessel;   said floor care apparatus being characterized by said cleaning wand assembly including a flexible hose and first and second telescoping sections.   
   
   
       2 . The floor care apparatus of  claim 1  wherein said actuator includes a plug for sealing and closing an open end of said cleaning wand assembly when said cleaning wand assembly is in said first position. 
   
   
       3 . The floor care apparatus of  claim 2 , further including a spring connected to said flow control valve and biasing said flow control valve into a normally closed position. 
   
   
       4 . The floor care apparatus of  claim 3 , wherein said flow control valve includes a pivot shaft and said valve body and said actuator pivot about a pivot axis defined by said pivot shaft. 
   
   
       5 . The floor care apparatus of  claim 1 , further including a spring connected to said flow control valve and biasing said flow control valve into a normally closed position. 
   
   
       6 . The floor care apparatus of  claim 5 , wherein said flow control valve includes a pivot shaft and said valve body and said actuator pivot about a pivot axis defined by said pivot shaft. 
   
   
       7 . The floor care apparatus of  claim 1 , wherein said dirt collection vessel is a filter bag. 
   
   
       8 . The floor care apparatus of  claim 1 , wherein said dirt collection vessel is a dirt cup. 
   
   
       9 . The floor care apparatus of  claim 8 , wherein said dirt cup includes a cylindrically shaped dirt collection chamber, a tangentially directed inlet and an axially directed outlet. 
   
   
       10 . The floor care apparatus of  claim 9 , further including a primary filter in said dirt cup upstream from said axial outlet. 
   
   
       11 . The floor care apparatus of  claim 10 , further including a secondary filter in said first air flow pathway between said dirt cup and said suction generator. 
   
   
       12 . The floor care apparatus of  claim 11 , further including a final filter in said first air flow pathway downstream from said suction generator. 
   
   
       13 . The floor care apparatus of  claim 12 , further including at least one rotary agitator carried by said nozzle assembly adjacent said suction inlet. 
   
   
       14 . The floor care apparatus of  claim 1 , further including at least one rotary agitator carried by said nozzle assembly adjacent said suction inlet. 
   
   
       15 . The floor care apparatus of  claim 1 , wherein said canister assembly is pivotally connected to said nozzle assembly. 
   
   
       16 . The floor care apparatus of  claim 7 , wherein said cleaning wand assembly includes a control handle.
