Electric cleaner

Abstract

A separation wall ( 212 ) with a larger thickness than a separation wall ( 209 ) is provided at the central part in a left/right direction of a suction inlet main body ( 201 ). This is made so that the central part of a separate suction inlet passage ( 211 ) has a smaller height in a thickness direction than both sides in the left/right direction of the separate suction inlet passage. As a result, a separate suction inlet passage ( 211 b ), connected to a concentration opening ( 210 ) from the left and right sides at the front of the separate suction inlet passage ( 211 ), has a larger height than a separate suction inlet passage ( 211 a ) at the central part of the separate suction inlet passage ( 211 ). This way, plural suction inlets are provided in the suction inlet main body, and each of the suction inlets can be selectively used depending on each cleaning on floor surfaces.

1 . An electric vacuum cleaner that suctions dust, together with airflow generated by operation of an electric blower, through a suction inlet of a suction inlet body and then introduces the auctioned airflow into a dust collector so as to collect the dust, 
 wherein the suction inlet body is provided with a plurality of suction inlets and a plurality of suction inlet passages respectively connecting with the plurality of suction inlets, and    wherein, at least one of the plurality of suction inlet passages is provided with adjusting means for adjusting a ratio of air passage volume in a center portion of the respectively connected suction inlet to air passage ratio in both side portions thereof,    wherein the adjusting means is so formed as to change a thickness-direction spatial dimension of a portion of the at least one suction inlet passage leading from the center portion of the respectively connected suction inlet inward, and    wherein thickness-direction spatial dimensions of portions of the at least one suction inlet passage leading from the both side portions of the respectively connected suction inlet inward is greater than the thickness direction spatial dimension of the portion of the at least one suction inlet passage leading from the center portion of the respectively connected suction inlet inward.    
   
   
       2 . The electric vacuum cleaner according to  claim 1 , 
 wherein a suction inlet switch device is provided which switches among the plurality of suction inlets for use.    
   
   
       3 .- 6 . (canceled)  
   
   
       7 . The electric vacuum cleaner according to  claim 1 , 
 wherein a partition wall as a partition between the at least one suction inlet passage provided with the adjusting means and another of the plurality of suction inlet passages which is adjacent thereto and connecting with another respectively connected suction inlet has on a side thereof facing the another respectively connected suction inlet, a partition wall surface that is rectilinear in a right/left direction thereof.    
   
   
       8 . The electric vacuum cleaner according to  claim 2 , 
 wherein a partition wall as a partition between the at least one suction inlet passage provided with the adjusting means and another of the plurality of suction inlet passages which is adjacent thereto and connecting with another respectively connected suction inlet has, on a side thereof facing the another respectively connected suction inlet, a partition wall surface that is rectilinear in a right/left direction thereof.    
   
   
       9 .- 11 . (canceled)  
   
   
       12 . The electric vacuum cleaner according to  claim 1  wherein, for each of the portions of the at least one suction inlet passage leading from the both side portions of the respectively connected suction inlet inward and the portion of the at least one suction inlet passage leading from the center portion of the respectively connected suction inlet inward, the thickness-direction spatial dimension as measured at an inward side is greater than or equal to the thickness-direction dimension passage as measured at a suction inlet side.  
   
   
       13 . The electric vacuum cleaner according to  claim 2  wherein, for each of the portions of the at least one suction inlet passage leading from the both side portions of the respectively connected suction inlet inward and the portion of the at least one suction inlet passage leading from the center portion of the respectively connected suction inlet inward, the thickness-direction spatial dimension as measured at an inward side is greater than or equal to the thickness-direction dimension passage as measured at a suction inlet side.  
   
   
       14 . The electric vacuum cleaner according to  claim 7  wherein, for each of the portions of the at least one suction inlet passage leading from the both side portions of the respectively connected suction inlet inward and the portion of the at least one suction inlet passage leading from the center portion of the respectively connected suction inlet inward, the thickness-direction spatial dimension as measured at an inward side is greater than or equal to the thickness-direction dimension passage as measured at a suction inlet side.  
   
   
       15 . The electric vacuum cleaner according to  claim 8  wherein, for each of the portions of the at least one suction inlet passage leading from the both side portions of the respectively connected suction inlet inward and the portion of the at least one suction inlet passage leading from the center portion of the respectively connected suction inlet inward, the thickness-direction spatial dimension as measured at an inward side is greater than or equal to the thickness-direction dimension passage as measured at a suction inlet side.
