2 and 3 show the structure of the vacuum cleaner 100 according to the first embodiment of the present invention in a state before and after transformation.

First, referring to Figure 2, the vacuum cleaner 100 of the present embodiment is a dust collecting room 120, the main body 110 is equipped with a suction motor 130 and the moving wheels 140, 141, and sucks in dust The pipe 150 includes a suction head 160, a hose 170 connecting the pipe 150 to the first port 111 of the main body 110 communicating with the dust collecting room 120. Therefore, as in the conventional cleaner, pressing the operation switch 152 attached to the handle 151 of the pipe 150 operates the suction motor 130, and thus the suction head 160, the pipe 150 and the hose 170 After the dust is sucked into the dust collecting room (120).

Here, the first feature of the present invention, the suction head 160 can be separated from the pipe 150, the hose 170 is also connected to the dust collecting room 120 of the main body 110, the first port 111 Can be separated from each other and combined in different places. In other words, when used plainly as in the conventional basic structure, it can be used in the state before the transformation as shown in FIG. However, if you want to move more smoothly, disassemble between the suction head 160 and the pipe 150, the hose 170 and the first port 111, respectively, and then directly to the suction head 160 Inserted into the port 111, the ends of the separated pipe 150 and the hose 170 is coupled to the second and third ports 112 and 113 provided separately in the main body 110 to have a structure as shown in FIG. Transform In this case, the pipe 150 can be cleaned while pushing the main body 110 as if it is a handle of a cart. And, although not shown in the drawing, the hose 170 and the third port 113 are provided with connection terminals, respectively, and when they are connected to each other, the signal of the operation switch 152 in the pipe 150 is transmitted to the motor 130. It becomes possible.

And, the second feature of the present invention, when turning the pipe 150 coupled to the second port 112 as described above, the steering wheel 140, which depends on the front of the wheels on the body 110, as if the steering wheel is It's easy to go back and turn around. That is, the front of the main body 110 has a steering wheel 140 that can actively change the direction, and the rear is fixed wheel 141 that can only rotate straight, the steering wheel 140 will be described below It is linked with the second port 112 by a steering unit to be rotated, and when the pipe 150 is turned, the direction is changed as well.

4 is a view reconstructing the drawing of the first embodiment based on the skeleton of such a steering unit. As shown, the second port 112 to which the pipe 150 is connected is connected to the handle shaft 180 and the universal joint 182 provided on the main body 110. Therefore, when the pipe 150 rotates, the second port 112 to which the pipe 150 is inserted rotates, and at the same time, the handle shaft 180 connected to the universal joint 182 also rotates. A plurality of link members 181 are connected between the handle shaft 180 and the steering wheel 140. The link members 181 convert the rotational motion of the handle shaft 180 into a proper linear motion and a pivoting motion, and finally, change the direction of the steering wheel 140. For example, when the pipe 150 is turned clockwise as in FIG. 5A, the handle shaft 180 is also turned clockwise, and the link members 181 connected thereto move the steering wheel 140 as shown in the drawing. Turn right to make a right turn. On the contrary, when the pipe 150 is rotated counterclockwise as shown in FIG. 5B, the handle shaft 180 also rotates counterclockwise, and the link members 181 also move in the opposite direction to the left to rotate the steering wheel 140. Play as possible. This is similar to the steering wheel operation of the car, since the direction of travel of the steering wheel 140 rotates along the direction of turning the pipe 150, it is very easy to change the direction while pushing the main body 110 when the operation is used a little. Easier Therefore, by operating the suction motor 130 to drive the steering wheel 140 of the main body 110 while sucking dust, it is possible to clean very quickly and easily around the room.

On the other hand, in this example, the movement of the wheel is pushed by a person, as shown in Figure 6 installed on the fixed wheel 141, the electric motor including a drive motor 191, reducer 192 and the electric belt 193 It can also be configured to move by the power of electricity. Of course, in this case, the switch may be installed on the handle 151 of the pipe 150 similarly to the operation switch 152 of the suction motor 130.

Next, Figure 7 shows a vacuum cleaner 200 according to a second embodiment of the present invention. In this embodiment, the suction head 260, the pipe 250, and the hose 270 are separated from their usual positions, and the basic parts are used by modifying them by inserting them into the first, second, and third ports 211, 212, 213, respectively. The principle is the same as in the first embodiment described above. However, the steering unit is configured differently from the first embodiment, and the drawing also shows a skeleton of the steering unit.

Once in this embodiment, the second port 212 and the handle shaft 280 for plugging the pipe 250 is provided in a pair of right and left. That is, in the above-described first embodiment, although the second port 112 and the handle shaft 180 were in the rear center portion of the main body 110, the pairs are arranged symmetrically from side to side. This is for the convenience of selective use of the right handed and left handed. For example, if it is convenient for the right handed to fit the second port 212 on the right side, the left handed to drive the second port 212 on the left side. It can be convenient. In other words, since the convenient location varies depending on which user mainly uses the hand, the user can select and use it. Of course, the link members 281 are connected so that the same operation can be inserted in any place. The second port 212 and the handle shaft 280 have a structure of a lever lever. That is, the second port 212 is configured in a lever type such that one end is coupled to the handle shaft 280 like a lever so as to rotate a predetermined angle. Accordingly, when the pipe 250 is inserted and rotated at a predetermined angle, that is, the steering wheel 240 rotates in the corresponding direction when the pipe 250 is rotated to the left or right. Therefore, it is very easy to drive the main body 210 by moving the pipe 250 while fitting the desired side of the pair of second ports 212 to the left and right. In addition, in the first embodiment and the second embodiment, the auxiliary wheel for assisting the steering wheel may be configured as a free rotating wheel (aka 'caster wheel') 241 instead of the fixed wheel. Therefore, since the auxiliary wheel 241 is free to change direction, the direction of the main body can be more easily changed.

On the other hand, the steering units of the first and second embodiments mentioned above may be reconfigured in various forms by combining mutual unit elements.

As described above, the vacuum cleaner according to the present invention provides the following effects.

First, if necessary, the suction head, pipes and hoses can be reassembled with a steering wheel member to directly push the main body, and can be assembled and used like a general vacuum cleaner handle. .

Second, the wheels attached to the main body can be adjusted by moving the steering wheel while pushing or pulling from the rear, so the movement is very convenient.

Third, options for left-handed and right-handed are added, further improving the ease of use.

Fourth, it is also possible to selectively move the main body by employing an electric unit.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
