Upright type vacuum cleaner

Abstract

An upright type vacuum cleaner is disclosed. An object of the present invention is to provide an upright type vacuum cleaner having a movement direction changed smoothly and quickly as necessary during the movement. The upright type vacuum cleaner includes a body, a wheel member provided in the body, the wheel member including a main rotation member rotatably provided in the body, and an auxiliary rotation member rotatably provided in the main rotation member to be rotated in a predetermined rotational direction different from a rotational direction of the main rotation member.

1 . A upright type vacuum cleaner comprising:
 a body;   a wheel member provided in the body, the wheel member comprising:   a main rotation member rotatably provided in the body; and   an auxiliary rotation member rotatably provided in the main rotation member to be rotated in a predetermined rotational direction different from a rotational direction of the main rotation member.   
     
     
         2 . The upright type vacuum cleaner as claimed in  claim 1 , further comprising:
 an accommodation part provided in the main rotation member to accommodate the auxiliary rotation member and the plurality of the auxiliary rotation member are provided and the plurality of the accommodation parts are provided correspondingly.   
     
     
         3 . The upright type vacuum cleaner as claimed in  claim 1 , further comprising:
 a suction nozzle connected with the body, wherein the wheel member comprising the main rotation member and the auxiliary rotation member is installed in the suction nozzle.   
     
     
         4 . The upright type vacuum cleaner as claimed in  claim 3 , wherein the plurality of the wheel members are provided and the plurality of the wheel members are rotatably provided in both opposite side portions of the body and both opposite side portion of the suction nozzle. 
     
     
         5 . The upright type vacuum cleaner as claimed in  claim 3 , wherein the wheel member comprises a first wheel member and a second wheel member formed larger than the first wheel member and the first wheel member is arranged in the suction nozzle and the second wheel member is arranged in the body. 
     
     
         6 . The upright type vacuum cleaner as claimed in  claim 5 , wherein auxiliary rotation members of the first wheel member are arranged in both side portions of a main rotation member in plural lines and auxiliary rotation members of the second wheel member are arranged along an outer circumferential surface of a main rotation member in a single line. 
     
     
         7 . The upright type vacuum cleaner as claimed in  claim 1 , wherein the rotational direction of the main rotation member and the rotational direction of the auxiliary rotation member are formed different to a predetermined angle. 
     
     
         8 . The upright type vacuum cleaner as claimed in  claim 1 , wherein an outermost portion of the auxiliary rotation member is extended outward further than an outermost portion of the main rotation member to be contactable with a floor. 
     
     
         9 . An upright type vacuum cleaner comprising:
 a body;   a motor accommodation part accommodating a motor generating a vacuum pressure, in communication with the body; and   a wheel member provided in the motor accommodation part, in contact with a floor.   
     
     
         10 . The upright type vacuum cleaner as claimed in  claim 9 , wherein the wheel member is configured to surround an outer circumferential surface of the motor accommodation part and the wheel member comprising comprises,
 a main rotation member rotatably provided in the motor accommodation part; and   an auxiliary rotation member provided in the main rotation member, having a predetermined rotational direction different from a rotational direction of the main rotation member.   
     
     
         11 . The upright type vacuum cleaner as claimed in  claim 9 , wherein the plurality of the wheel members are provided in an outer circumferential surface of the motor accommodation part, movable in a movement direction of the body. 
     
     
         12 . The upright type vacuum cleaner as claimed in  claim 9 , wherein the motor accommodation part is rotatably provided in the body and the wheel member comprises a roller-shaped auxiliary rotation member arranged to be rotatable in a predetermined rotational direction from a rotational direction of the motor accommodation part. 
     
     
         13 . The upright type vacuum cleaner as claimed in  claim 9 , further comprising:
 a supporting leg extendedly provided in a rear portion of the body; and   a wheel member rotatably provided in the supporting leg, the wheel member comprising:   a main rotation member; and   an auxiliary rotation member rotatably provided in the main rotation member, having a predetermined rotational direction different from a rotational direction of the main rotation member.   
     
     
         14 . The upright type vacuum cleaner as claimed in  claim 9 , further comprising:
 a suction nozzle connected with the body; and   a wheel member provided in the suction nozzle, the wheel member comprising:   a main rotation member; and   an auxiliary rotation member rotatably provided in the main rotation member, having a predetermined rotational direction different from a rotational direction of the main rotation member.
