Dust receptacle and steam vaccum cleaner

Abstract

The present invention provides a dust receptacle and a steam vacuum cleaner using the same, wherein the dust receptacle comprises an auxiliary filter in a dust collection bin to cause dust to settle or be distributed evenly inside the dust collection bin, and therefore to extend a cleaning cycle or replacement cycle of a main filter.

1 . A steam vacuum cleaner comprised of:
 a main body;   a motor assembly coupled to said main body; and   a dust receptacle coupled to said main body, wherein said dust receptacle includes a dust collection bin having a main filter and an auxiliary filter which are separated.   
     
     
         2 . The steam vacuum cleaner of  claim 1 , wherein the dust collection bin includes a bin inlet having a door that is opened by force of air being sucked into the collection bin and closed by gravity when air is not sucked into the collection bin. 
     
     
         3 . The steam vacuum cleaner of  claim 1 , wherein the auxiliary filter has a trapezoidal shape. 
     
     
         4 . The steam vacuum cleaner of  claim 3 , wherein the auxiliary filter includes:
 a front face and a bottom face which are both shut,   a top face, a left lateral face and a rear face which are both screened, and   a right lateral face which is open.   
     
     
         5 . The steam vacuum cleaner of  claim 4 , wherein the front face and a bottom face of the auxiliary filter are both screened. 
     
     
         6 . A dust receptacle for use within a steam vacuum cleaner, comprising:
 a dust collection bin including a bin inlet, a bin outlet, and a dust collecting chamber inside;   a cover for opening/closing the dust collection bin;   a main filter mounted to the bin exhaust of the dust collection bin; and   an auxiliary filter loaded in the dust collecting chamber and separated from the main filter.   
     
     
         7 . The dust receptacle of  claim 6 , wherein the bin inlet has a door that is opened by force of air being sucked into the collection bin and closed by gravity when air is not sucked into the collection bin. 
     
     
         8 . The dust receptacle of  claim 6 , wherein the auxiliary filter has a trapezoidal shape. 
     
     
         9 . The dust receptacle of  claim 8 , wherein the cover is provided with a lateral pressing piece and a vertical pressing piece for pressing and supporting the auxiliary filter in order to further secure the auxiliary filter into place. 
     
     
         10 . The dust receptacle of  claim 8 , wherein the auxiliary filter includes:
 a front face and a bottom face which are both shut,   a top face, a left lateral face and a rear face which are both screened, and   a right lateral face which is open.   
     
     
         11 . The dust receptacle of  claim 10 , wherein the front face and a bottom face of the auxiliary filter are both screened. 
     
     
         12 . A steam vacuum cleaner comprising:
 a base assembly having a dust receptacle coupled to a suction nozzle; and   a suction motor coupled to said dust receptacle for sucking air in through the suction nozzle and filtering said air through said dust receptacle;   wherein the dust receptacle is comprised of a dust collection bin having a bin inlet, a bin outlet, and a dust collecting chamber; and further wherein said dust collection bin includes a main filter and a separate auxiliary filter.   
     
     
         13 . The steam vacuum cleaner of  claim 12 , wherein the auxiliary filter has a trapezoidal shape. 
     
     
         14 . The steam vacuum cleaner of  claim 13 , wherein the auxiliary filter includes:
 a front face and a bottom face which are both shut,   a top face, a left lateral face and a rear face which are both screened, and   a right lateral face which is open.   
     
     
         15 . The steam vacuum cleaner of  claim 14 , wherein the front face and a bottom face of the auxiliary filter are both screened. 
     
     
         16 . The steam vacuum cleaner of  claim 12  further comprising:
 a cover for opening/closing the dust collection bin, said cover having a lateral pressing piece and a vertical pressing piece for pressing and supporting the auxiliary filter in order to further secure the auxiliary filter into place.
