Cleaning tool, electric cleaner and cordless vacuum cleaner

Abstract

A cleaning tool includes: a body including an upper case and a lower case, and for sucking dust from the surface to be cleaned from the lower case; and a joint located at one end side of the body with respect to a center of the body in a longitudinal direction of the body. The joint includes a first rotating portion and a second rotating portion. The second rotating portion is connected to the body so as to be rotatable relative to the body around a second axis of rotation being parallel to the longitudinal direction of the body. The first rotating portion is rotatably connected to the second rotating portion so as to be rotatable relative to the second rotating portion around a first axis of rotation being at an intersecting position or a skewed position with respect to the second axis of rotation.

1 . A cleaning tool, comprising:
 a body including an upper case and a lower case, and for sucking dust from the surface to be cleaned from the lower case; and   a joint located at one end side of the body with respect to a center of the body in a longitudinal direction of the body,   wherein the joint includes a first rotating portion and a second rotating portion,   wherein the second rotating portion is connected to the body so as to be rotatable relative to the body around a second axis of rotation being parallel to the longitudinal direction of the body,   wherein the first rotating portion is rotatably connected to the second rotating portion so as to be rotatable relative to the second rotating portion around a first axis of rotation being at an intersecting position or a skewed position with respect to the second axis of rotation, and   wherein the second rotating portion is connected to the one end side of the upper case so that the first axis of rotation is located outside the upper case in the longitudinal direction.   
     
     
         2 . The cleaning tool according to  claim 1 , wherein the second rotating portion is connected to an end portion of the one end side of the upper case. 
     
     
         3 . The cleaning tool according to  claim 1 , wherein the second rotating portion is located on a side of the upper case in the longitudinal direction. 
     
     
         4 . The cleaning tool according to  claim 1 , further comprising a suction pipe,
 wherein a bottom surface of the lower case faces the surface to be cleaned,   wherein when the body is placed on the surface to be cleaned, the whole of the first rotating portion and the second rotating portion are positioned above the surface to be cleaned,   wherein with rotation about a central axis of the suction pipe, the first rotating portion and second rotating portion can be rotated while maintaining an opening direction of a suction opening formed on the bottom surface downward,   wherein an orientation of the body is changeable between a first form in which the body moves in a width direction perpendicular to the longitudinal direction and a second form in which the body moves in the longitudinal direction, and   wherein a rotation of the suction pipe about the central axis changes the orientation of the body between the first form and second form.   
     
     
         5 . The cleaning tool according to  claim 1 , wherein the second rotating portion is positioned at center in a width direction perpendicular to the longitudinal direction. 
     
     
         6 . The cleaning tool according to  claim 1 , wherein in a top view, the body exhibits a line-symmetric appearance about the second axis of rotation. 
     
     
         7 . The cleaning tool according to  claim 1 , wherein the second axis of rotation is positioned on the lower case side than an upper end of the upper case. 
     
     
         8 . The cleaning tool according to  claim 1 , wherein an upper end of the second rotating portion is at the same height as an upper end of the upper case or is positioned on the lower case side than the upper end of the upper case. 
     
     
         9 . The cleaning tool according to  claim 1 , wherein the second rotating portion is rotatable around the second axis of rotation in a range of 0 to 180 degrees. 
     
     
         10 . An electric cleaner, comprising:
 the cleaning tool according to  claim 1 ; and   a cleaner main body including an electric air blower.   
     
     
         11 . A cordless vacuum cleaner, comprising:
 the cleaning tool according to  claim 1 ;   a cleaner main body including an electric air blower;   a suction pipe connecting the cleaning tool and the cleaner main body; and   a handle provided on the cleaner main body,   wherein a central axis of the handle is coincide with a central axis of the cleaner main body.   
     
     
         12 . A cordless vacuum cleaner, comprising:
 the cleaning tool according to  claim 1 ;   a cleaner main body including an electric air blower; and   a suction pipe connecting the cleaning tool and the cleaner main body;   wherein a central axis of the cleaner main body and a central axis of the suction pipe are parallel to each other.   
     
     
         13 . A cordless vacuum cleaner, comprising:
 the cleaning tool according to  claim 1 ;   a cleaner main body including an electric air blower;   a suction pipe connecting the cleaning tool and the cleaner main body; and   a handle provided on the vacuum cleaner body and gripped when cleaning,   wherein a central axis of the handle is coincide with a central axis of the electric air blower.   
     
     
         14 . A cordless vacuum cleaner, comprising:
 the cleaning tool according to  claim 1 ;   a cleaner main body including an electric air blower;   a suction pipe connecting the cleaning tool and the cleaner main body; and   a handle provided on the vacuum cleaner body and gripped when cleaning,   wherein a central axis of the handle is coincide with a central axis of the suction pipe.
