A canister type vacuum cleaner is disclosed. An object of the present invention is to provide a canister type vacuum cleaner including a suction nozzle (15) having a movement direction changed smoothly and quickly, even in case of colliding with an obstacle. The canister type vacuum cleaner includes a body (10), a wheel member (100) rotatably provided in the body (10) and supporting the body (10), the wheel member (100) including a main rotation (111 ) member provided in the body (10) and an auxiliary rotation member (112) rotatably provided in the main rotation (111 ) member to be rotated along a predetermined rotational direction different from a rotational direction of the main rotation member (111 ).
The present invention relates to a canister vacuum cleaner, and more particularly, to a canister vacuum cleaner in which the direction of the main body or the suction nozzle can be more easily achieved.
The vacuum cleaner is a device for collecting dust by collecting external dust using a vacuum pressure generated by a motor provided inside the main body.
Vacuum cleaners are largely classified into canister cleaners and upright cleaners according to their shape. In particular, the canister cleaner according to the present invention includes a main body including a motor, a dust collector, and a dust separator. A suction hose connected to the main body, and a suction nozzle provided at an end of the suction hose.

When the main body is moved by the rolling motion of the wheel member, movement in a space free of obstacles may be freely made. However, when the moving body collides with the obstacle, the direction of the force applied to the main body by the collision is determined by the wheel member. When the rolling direction is different from the rolling direction, rolling friction does not occur between the surface and the bottom of the wheel member, and sliding friction occurs.
Therefore, there is a problem that the main body may be turned upside down, or due to the problem that the wheel member does not roll due to the sliding friction of the wheel member, but is brought into contact with the floor and is dragged.
In addition, when the main body is located behind the user, there is a problem in that the direction must be changed by holding the main body in order to move the direction of the main body, particularly when the main body is located in a limited space.
On the other hand, when the main body or the suction nozzle is moved in any direction and then in an oblique or orthogonal direction with the direction, there is also a problem that such a motion trajectory draws an arc, thereby increasing the rotation radius.
The present invention is to solve this problem, it is possible to easily change the direction of the main body or suction nozzle, and to provide a canister-type vacuum cleaner that can be quickly changed in the event of a collision with an object. have.
The present invention for achieving the above object, the main body; comprising a wheel member rotatably provided on the main body and supporting the main body, the wheel member is provided on the main body rotatably; It provides a canister vacuum cleaner comprising an auxiliary rotating member rotatably provided on the main rotating member so as to rotate in a rotational direction different from the rotating direction of the main rotating member.

By the present invention, the direction of the main body or the suction nozzle can be made more easily, and the rotation radius due to the change of direction is significantly reduced than before, so that the direction can be easily changed even in a narrow cleaning space.
In addition, even when the main body collides with the obstacle, there is an advantage that can be quickly switched to the direction to move again after the user quickly changes the direction of the impact force.

Here, the wheel member 100 is the main rotating member (111,121) rotatably provided in the main body 10, and a plurality of auxiliary rotating member (not shown) rotatably disposed on the outer portion of the main rotating member (111,121) ( 112,122).
Looking at the characteristics of such a wheel member 100, the rotational direction of the main rotary member (111, 121) and the rotational direction of the auxiliary rotary member (112, 122) is designed differently, freely depending on the direction of the force applied to the main body (10) It is movable.
That is, when the user pushes the main body 10 in the front-rear direction using a foot or a hand, the main body 10 may move in the front-rear direction according to the rotation of the main rotating members 111 and 121.
In addition, when the user moves the main body 10 to the left and right, the main body 10 can move in the left and right directions in accordance with the rotation of the auxiliary rotating members (112, 122).
In addition, rotation shaft support parts 113 and 123 are provided at the center of the main rotation members 111 and 121, and the rotation shaft support parts 113 and 123 are rotatably coupled to the main body 10.
As shown in Figs. 2 (a) and 2 (b). A plurality of auxiliary rotating members 112 are provided on the main rotating member 111 of the first wheel member 110 to be rotatable, and the main rotating member 111 may be accommodated in the auxiliary rotating member 112. ) Is provided with a receiving portion 114.

On the other hand, the outermost part of the auxiliary rotating member 112 is projected more than the outermost part of the main rotating member 111 should be in contact with the floor.
This is because when the instantaneous direction change is made even while moving in the rotational direction of the main rotating member 111 can move in the rotational direction of the auxiliary rotating member (112).
FIG. 2 (b) shows that the number of the auxiliary rotating members 112 is smaller and the size of the auxiliary rotating members 112 is larger than that of the first wheel member shown in FIG. 2 (a).
In this case, when the force is applied in the A direction, the main rotating member 111 rotates in the A direction, and at the same time, each of the auxiliary rotating members 112 sequentially moves in the A direction while contacting the floor. The same is true in the opposite direction.
On the other hand, when the force is applied in the B direction, the auxiliary rotating member 112 in contact with the floor is rotated, the entire first wheel member 110 moves in the B direction. At this time, the main rotating member 111 does not rotate, or slightly rotates.
Therefore, the wheel member as shown in Figure 2 (a) (b) can be freely moved in four directions according to the user's intention.
