1 and 2 are perspective views of the vacuum cleaner according to the present embodiment, Figure 1 is a view showing a state of the vacuum cleaner when cleaning the bottom surface, Figure 2 is a case of cleaning the space outside the floor surface A diagram showing a state of the vacuum cleaner.

1 and 2, this embodiment proposes an upright vacuum cleaner.

The vacuum cleaner 1 includes a main body 10 having a suction motor therein, a suction nozzle 20 connected to the main body 10, and suctioning air containing dust on a bottom surface thereof, and the main body 10. A dust collecting device 30 which is combined with 10 to store dust separated from the air sucked into the main body 10, a handle 40 to allow a user to grip, and a connection to the handle 40 And a suction pipe (50) connected to the second suction device (90) for suctioning dust-containing air during cleaning of portions other than the bottom surface, and to the second suction device (90), and detachably coupled to the main body (50). ), A first suction device (80) connected to the suction pipe (50) for sucking air containing dust during cleaning of portions other than the bottom surface, and a connection hose (80) connecting the handle and the main body (80). Included.

In detail, the suction nozzle 20 sucks air containing dust on the bottom surface while moving in a state close to the bottom surface. A suction port (not shown) is formed at the bottom of the suction nozzle 20.

And, both sides of the suction nozzle 20 is provided with a wheel 21 to enable the movement of the suction nozzle 20.

The main body 10 is rotatably coupled to the suction nozzle 20. In addition, the main body 10 is rotated with respect to the suction nozzle 20 within a predetermined angle range. The upper side of the suction nozzle 20 is formed with a rotary lever 22 for controlling the rotation of the main body 10.

Therefore, when the user grasps the handle 40 and pulls the main body 10 backward while pressing the rotary lever 22 using the foot, the main body 10 is inclined backward.

In this case, the user can clean the bottom surface while adjusting the main body 10 to a desired angle according to his height.

The main body 10 includes a case 110 in which a suction motor is built, and air sucked through the suction nozzle 20 by being provided at an upper side (right side in FIG. 1) of the case 110. Suction duct 140 to be moved to 30 and the other side (left in FIG. 1) of the case 110 is provided to discharge the air discharged from the dust collector 30 to the suction motor side The mounting unit 160 is provided on the duct 150, the discharge duct 150, and the suction duct 140, and the suction pipe 50 is mounted thereon.

In detail, a seating portion 116 seated with the first suction device 50 is formed on the front surface of the case 110. Thus, the seating portion 116 is located below the suction duct 140 and the discharge duct 160.

In addition, the seating portion 116 is recessed to a predetermined depth from the front of the case 110 to the rear, and is formed in a shape and size corresponding to the first suction device 80. In addition, the first suction device 80 is seated on the seating portion 116 in a state coupled with one side of the suction pipe 50. In addition, the first suction device 80 is exposed to the outside of the main body 10 while the first suction device 80 is seated on the seating portion 116. Therefore, the first suction device 80 may be described as forming part of the front exterior of the main body 10 in a state of being seated on the seating portion 116.

As the first suction W device 80 is seated on the seating portion 116 recessed in the main body 10, the first suction device 80 does not protrude to the outside of the main body 10. Deterioration of the aesthetics of the main body 10 is prevented.

The first suction device 80 is detachably connected to the suction pipe 50. Coupling of the first suction device 80 and the suction pipe 50 may be made in an interference fit method by the difference in diameter, or may be mutually coupled by a lever. At this time, when the lever is provided in any one of the first suction device 80 and the suction pipe 50, the other is formed of the insertion hole is inserted into the hook formed in the lever. In the present embodiment, it is noted that there is no limitation in the coupling manner of the first suction device 80 and the suction pipe 50.

When the first suction device 80 and the suction pipe 50 are detachably coupled in this manner, the first suction device 80 is separated from the suction pipe 50, and then another suction device, for example, Cleaning can be done by combining crevice tools.

In addition, when the suction pipe 50 is mounted to the mounting unit 160, the suction pipe 50 is located between the suction duct 140 and the discharge duct 150.

The mounting unit 160 is provided with a fixing device (not shown) for fixing the suction pipe 50 to the mounting unit 160. In addition, the suction pipe 50 is provided with a guide unit 70 for coupling the fixing device.

An upper side of the mounting unit 160 is provided with an operation button 200 for releasing the fixing in the state in which the suction pipe 50 is fixed to the mounting unit 160 by the fixing device. In addition, a part of the operation button 200 is protruded out of the mounting unit 160 so that a user can operate it.

The fixing device includes at least one link member and a hook connected to the link member and selectively coupled to the guide unit 70. In addition, the guide unit 70 is formed with an insertion hole in which the hook is selectively inserted. In addition, at least a portion of the hook is exposed to the outside of the mounting portion 160 to be inserted into the guide unit.

Therefore, when the suction pipe 50 is mounted to the mounting portion 160, the hook is inserted into the guide unit 70, so that the suction pipe 50 is firmly fixed to the mounting portion 160. On the contrary, when the operation button 200 is operated, the hook is removed from the guide unit 70 so that the suction pipe 50 is detachable from the mounting unit 160.

On the other hand, the suction pipe 50 is composed of a plurality of members can be adjusted in length. The second suction device 90 is detachably coupled to the other side of the suction pipe 50. The suction pipe 50 is selectively coupled to the second suction device 90 by a coupling lever provided in the second suction device 90 to be described later. In addition, the second suction device 90 is detachably coupled to the handle 40.

Therefore, after the suction pipe 50 connected to the first suction device 80 is separated from the second suction device 90, the second suction device 90 may be cleaned.

On the other hand, the dust collecting device 30, the dust contained in the air to be separated, the separated dust is to be stored. The dust collecting device 30 is detachably coupled to the main body 10. In the present embodiment, the dust collecting device 30 allows dust to be separated by a cyclone method. However, the idea of this embodiment is not limited to the dust separation method, and in addition to the dust collector, a dust bag in which dust is stored and air passes can be used.

On the other hand, in the general upright type vacuum cleaner, since the suction nozzle combined with the main body moves along the bottom surface to perform cleaning, a place other than the bottom surface is difficult to clean.

However, in this embodiment, in order to enable the cleaning of the space other than the bottom surface, the suction pipe 50 can be separated from the main body 10. Then, cleaning of portions other than the bottom surface may be performed by using the first suction device 80 or the second suction device 90.

In detail, to clean the bottom surface, as shown in FIG. 1, the main body 10 is rotated with respect to the suction nozzle 20 while the suction pipe 50 is coupled to the main body 10. Then, the user cleans the bottom surface while moving the suction nozzle 20 along the bottom surface.

On the other hand, in order to clean the parts other than the bottom surface, as shown in FIG. 2, after separating the suction pipe 50 from the main body 10 in the state in which the main body 10 is upright, the first suction device 80 or the second suction device 90 is used to suck the dust-containing air. In this case, when cleaning is performed using the second suction device 90, the suction pipe 50 should be separated from the second suction device 90 as described above.

As such, two flow paths through which air can flow are formed in the main body 10 to selectively clean the suction nozzle 20 or the suction devices 80 and 90.

3 is a partial cross-sectional view showing a flow path structure inside the main body.

Referring to FIG. 3, the body 10 includes a case 110 in which a suction motor is embedded. Rotating shafts 112 are formed at both sides of the case 110 to allow the main body 10 to rotate with respect to the suction nozzle.

The case 110 is provided with a suction flow pipe 120. The suction passage pipe 120 is connected to the suction nozzle 20 so that the air sucked through the suction nozzle 20 is moved into the case 110. The suction flow path pipe 120 is formed of a flexible material freely flowing.

The case 110 is sucked through the first suction passage 132 through which the air sucked by the suction nozzle 20 is sucked, and the first suction device 80 or the second suction device 90. A second suction passage 134 is formed through which air is sucked. The first suction passage 132 communicates with the second suction passage 134.

The suction duct 140 provided on the upper side of the case 110 communicates with the suction port 31 of the dust collecting device 30. Therefore, the air sucked into the suction passages 132 and 134 is lifted along the suction duct 140 and then sucked into the dust collector 30.

One side of the discharge duct 150 provided on the upper side of the case 110 is in communication with the discharge port (not shown) of the dust collecting device 30, the other side is in communication with the suction motor. Therefore, the air discharged from the dust collecting device 30 is moved downward along the discharge duct 150 and then moved to the suction motor side.

Then, when the suction motor is operated, air is sucked from the outside by the suction force generated by the suction motor.

In this case, when the bottom surface is cleaned using the suction nozzle 20, the first suction device 80 is mounted on the main body 10 while being connected to the suction pipe. Air is sucked into the suction flow path 132 and air is not substantially sucked into the second suction flow path 134.

Here, "substantially no air is sucked" means that the amount of air flowing in the second suction passage 134 is significantly smaller than the amount of air flowing in the first suction passage 132, This means that the air may not be introduced into the second suction passage 134.

That is, in a state in which the first suction device 80 is seated on the seating portion 116, air is moved to a gap between the first suction device 80 and the seating portion 116 to allow the first suction device to move. It can be introduced into 80, but because the amount is small, it can be described that the air is not substantially sucked into the second suction passage 134 in the present embodiment.

On the other hand, when cleaning is performed using the first suction device 80 or the second suction device 90, air is sucked into the second suction flow path 134. Of course, air may also flow into the first suction passage 132. However, when the suction force is distributed and acted on the suction paths 132 and 134 as described above, the suction performance may be reduced.

Therefore, although not shown in the present embodiment, when the cleaning is performed using the suction devices 80 and 90, in order to prevent air from being sucked into the first suction flow path 132, the suction nozzle 20 ) Is provided with a flow path blocking device for blocking an air flow path formed therein.

That is, when cleaning is performed using the suction devices 80 and 90, the air flow path inside the suction nozzle 20 is blocked by the flow path blocking device, and air is sucked into the first suction flow path 132. Will not be.

Here, the operation of the flow path blocking device may vary depending on whether the main body 10 is upright (or rotated). That is, when the main body 10 is upright, the flow path blocking device blocks the air flow path of the suction nozzle 20. On the contrary, when the main body 10 rotates with respect to the suction nozzle 20 at a predetermined angle, the flow path blocking device opens the air flow path.

Hereinafter, the operation of the vacuum cleaner according to the state of the cleaning space will be described.

First, a case of cleaning the bottom surface such as the floor will be described with reference to FIG. 1.

When the bottom surface such as the floor is to be cleaned, the cleaning is performed using the suction nozzle 20. Therefore, the user manipulates the rotation lever 22 so that the main body 10 is rotated at a predetermined angle with respect to the suction nozzle 20.

Here, of course, when cleaning the bottom surface such as the floor, the first suction device 80 and the suction pipe 50 is of course mounted on the main body 10. When the main body 10 is rotated with respect to the suction nozzle 20, the first suction device 80 is rotated together with the main body 10 in a state of being seated on the main body 10.

And, the air containing the dust is sucked through the first suction nozzle 20 by the suction force generated by the suction motor. In addition, the sucked air is introduced into the dust collector 30 through the suction passage pipe 120, the first suction passage 132, and the suction duct 140.

In addition, the air containing the dust introduced into the dust collecting device 30 is discharged from the dust collecting device 30 in a state where the dust is separated. In addition, the air discharged from the dust collecting device 30 is introduced into the main body 10 through the discharge duct 150. In addition, the air introduced into the main body 10 passes through the suction motor and is finally discharged to the outside of the main body 10.

4 is a perspective view showing a state of performing cleaning using the first suction device.

Referring to FIG. 4, the first suction device 80 is formed in a flat shape having a smaller size and a smaller thickness than the suction nozzle.

In addition, when it is desired to clean a space other than the floor, for example, a lower space such as furniture or a staircase, it is difficult to clean using the suction nozzle 20, so that the first suction device 80 is Cleaning can be performed.

Therefore, the main body 10 is allowed to stand up to the suction nozzle 20. Then, the flow path blocking device blocks the air flow path inside the suction nozzle 20.

Then, the suction pipe 50 coupled to the main body 10 is separated. Then, the first suction device 80 connected to the suction pipe 50 is separated from the main body 10. Therefore, the user can clean the space other than the bottom surface by using the first suction device 80 separated from the main body 10.

At this time, the user can adjust the length of the suction pipe 50 as needed. That is, the suction pipe 50 is a tube (telescopic wand) that can be stacked with a plurality of members. In detail, the suction pipe 50 includes an outer member 510, an inner member 520 that is movable inside the outer member 510, and the inner member 520 that is moved relative to the outer member 510. A fixing member 530 is included to fix the position of the inner member 520 in a state (with the length of the suction pipe adjusted). For example, the fixing member 530 may be coupled to the outer member 510.

Length control structure of the suction pipe 50 may be applied in the same manner as the conventional structure, a detailed description thereof will be omitted. However, this embodiment reveals that there is a technical feature that the length of the suction pipe 50 selectively coupled to the main body 10 can be adjusted.

When the suction force is generated by the suction motor in a state in which the first suction device 80 is separated from the main body 10, air containing dust is sucked into the first suction device 80.

In addition, the air sucked into the first suction device 80 passes through the suction pipe 50, the second suction device 90, the handle 40, the connection hose 60, and the second suction flow path 134. It is moved to the suction duct 140. Then, the air moved to the suction duct 140 is sucked into the dust collecting device (30). Here, when the cleaning is performed using the first suction device 80, the second suction device 50 provides a passage through which air in the suction pipe 60 can move to the handle 40.

On the other hand, when the cleaning of the portion other than the bottom surface is completed, the suction pipe 50 is coupled to the main body 10. Then, the first suction device 80 connected to the suction pipe 50 is seated on the seating portion 116.

According to the present embodiment as described above, since the first suction device 80 is seated on the main body 10 in a state connected to the suction pipe 50, a user may connect the suction pipe 50 to the first suction device 80.

Referring to FIG. 5, the second suction device 90 is formed in a substantially cylindrical shape. Therefore, when it is desired to clean a space such as a table, a shelf, or the like located at a predetermined height from a floor or a gap of furniture, the second suction device 90 may be used for cleaning.

Therefore, when the cleaning is to be performed using the second suction device 90, the main body 10 is allowed to stand up to the suction nozzle 20. Then, the flow path blocking device blocks the air flow path inside the suction nozzle 20.

Then, the suction pipe 50 coupled to the main body 10 is separated. Then, the first suction device 80 connected to the suction pipe 50 is separated from the main body 10 together with the suction pipe 50. Thereafter, the suction pipe 50 to which the first suction device 80 is connected is separated from the second suction device 90.

Then, the user can perform the cleaning using the second suction device 90.

At this time, the second suction device 90 is provided with a brush for easily removing the dust attached to the surface to be cleaned. Therefore, the user can perform the cleaning more effectively using the brush.
