Hereinafter, a vacuum cleaner 10 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

It is to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described within the spirit and scope of the appended claims. Of course.

First, a vacuum cleaner 10 according to an embodiment of the present invention will be described with reference to FIG.

A main body 1 of the vacuum cleaner 10 is provided with a suction nozzle 17 through which foreign substances are introduced. When foreign substances are sucked through the suction nozzle (17), the foreign matter is introduced into the main body through the suction port (11).

The main body 1 may further include a motor assembly (not shown) for discharging the air introduced into the suction nozzle 17 to the exhaust port 13. The air sucked into the suction nozzle (17) can be discharged to the exhaust port (13) in the motor assembly (not shown).

The cyclone dust separator 17 can separate foreign matter mixed in the fluid introduced through the suction nozzle 17 by using the centrifugal force.

An auxiliary nozzle 4 selectively communicating with the suction nozzle 17 may be connected to the main body 1. That is, the auxiliary nozzle 4 may be housed in the main body 1 or selectively communicated with the suction port 11 by rotating about the rotation axis 452.

It is preferable that the auxiliary nozzle 4 has a shape suitable for removing foreign materials in narrow and deep places. In one embodiment, there may be a long auxiliary nozzle 4. The auxiliary nozzle 4 may be formed to extend not only in an elongated shape but also in a cylindrical shape in a longitudinal direction.

 FIG. 3 illustrates a state of use of an auxiliary nozzle according to an embodiment of the present invention. Fig. 3 (a) shows a state in which the auxiliary nozzle 4 is in the storage position, and Fig. 3 (c) shows the use position of the auxiliary nozzle 4. [

The auxiliary nozzle 4 is always connected to the main body 1 and can be selectively moved to a storage position or a use position when the auxiliary nozzle 4 is connected to the main body 1. [

Therefore, when foreign matter is difficult to remove by the suction nozzle 17 just like dust in a gap, foreign matter can be removed by moving the auxiliary nozzle 4 to the use position. The auxiliary nozzle 4 is connected to the main body 1 without being separated from the main body 1 even when the auxiliary nozzle 4 moves to the use position or moves to the storage position. Therefore, the risk of losing the auxiliary nozzle 4 can be reduced.

Further, a dust brush 6 connected to the auxiliary nozzle 4 may be provided. The dust brush 6 can sweep foreign substances or apply external force to the dust brush 6, which is not easy to fall off due to adhesive force with the cleaning surface, to facilitate suction. In addition, the dust brush 6 can be used when it is necessary to use a dust-type material having a soft material for cleaning an object on which surface damage is likely to be caused.

The dust brush 6 can be selectively moved to a use position and a storage position in a state where the dust brush 6 is connected to the auxiliary nozzle 4 or the main body 1. [ More details about the dust brush 6 will be described later.

Meanwhile, the main body 1 is provided with a space in which the dust brush 6 and the auxiliary nozzle 4 can be rotated and seated. The seat portion 7 is preferably provided at a lower portion of the main body 1 so that the dust brush 6 can be received when the dust brush 6 is folded and folded.

That is, it is possible to store the bonon nozzle 4 and the dust brush 5 using the internal space of the main body 1 without providing a space occupying a separate volume. Therefore, even if the auxiliary nozzle 4 and the dust brush 6 are always provided in the main body, the volume of the vacuum cleaner 10 is increased or the appearance of the vacuum cleaner 10 is not damaged.

The use state of the auxiliary nozzle 4 according to an embodiment of the present invention will be described in more detail with reference to FIG. According to an embodiment of the present invention, the auxiliary nozzle 4 may be provided on the main body 1 so as to be rotatable and translationally movable.

That is, FIG. 3 (a) shows a state in which the auxiliary nozzle 4 is in the storage position. The auxiliary nozzle 4 can be seated in the seat 7 of the main body 1 when the auxiliary nozzle 4 is rotated about the rotation axis 452 connected to the main body 1. [

When the auxiliary nozzle (4) is not used, the auxiliary nozzle (4) is stored in the storage position. When the user wishes to use the auxiliary nozzle 4 or the dust brush 6, the auxiliary nozzle 4 is rotated as shown in FIG. 3 (b). Then, the auxiliary nozzle 4 is rotated by a maximum rotation angle as shown in FIG. 3 (c) so that the auxiliary nozzle 4 reaches the use position.

At this time, a slot 12 for receiving the rotation shaft 452 is provided so that the rotation shaft 452 can rotate and translate. When the rotary shaft 452 is provided in the main body 1, the auxiliary nozzle 4 is provided with the slot 12. On the other hand, when the rotary shaft 452 is provided in the auxiliary nozzle 4, the slot 12 is preferably provided in the main body 1.

In particular, the elongated hole 12 may be formed on the inner surface of the seating portion 7. When the auxiliary nozzle 4 is formed on the inner surface of the seating part 7, the movement path when the auxiliary nozzle 4 is rotated to the accommodation position or the use position can be minimized.

On the other hand, when foreign matter is sucked by using the auxiliary nozzle 4, it is preferable that the auxiliary nozzle 4 is restricted from rotation. When an external force is applied to remove foreign matter, if the auxiliary nozzle 4 moves without being fixed, it is difficult to move the auxiliary nozzle 4 in a desired direction.

Therefore, a structure is required in which the auxiliary nozzle 4 is firmly fixed from the main body 1 at the use position, which will be described in more detail with reference to FIG.

4, when the auxiliary nozzle 4 rotates from the storage position to the use position and a force is applied to the auxiliary nozzle 4 in a rearward direction, rotation of the auxiliary nozzle 4 may be restricted have.

The auxiliary nozzle 4 includes a suction end 44 opposed to the object to be cleaned, a close end 45 which is selectively in close contact with the suction nozzle 17, and an extension end extending from the close end to the main body 1, And may include a connection end 46 where the rotation axis 452 is provided.

The close contact end 45 may include a contact surface 450. When the auxiliary nozzle 4 is in the use position, the suction port 11 and the auxiliary nozzle 4 can be selectively communicated.

Meanwhile, it is preferable that the auxiliary nozzle 4 and the suction port 11 are in close contact with each other so as not to be separated from each other at the use position. The suction face (18) at the end of the suction port (11) for engaging or coming into contact with the contact face (450) can be engaged with the contact face (450) by the translational motion of the auxiliary nozzle.

Therefore, the length and shape of the close contact surface 450 and the suction close contact surface 18 preferably correspond to each other.

A gasket (not shown) having an elastic material is provided on the suction port 11 or the close end portion 45 so that the auxiliary nozzle 4 and the suction port 11 can be engaged with each other without being separated from the use position .

A portion of the coherent end (45) may extend further in the longitudinal direction to form a connecting end (46). The extended portion smoothes the rotational motion of the auxiliary nozzle (4). In addition, rotation restriction of the auxiliary nozzle (4) is induced at the use position.

According to an embodiment of the present invention, the connection end 46 may extend in the longitudinal direction from the lower end of the close end 45. A rotation axis 452 may be formed at an end of the connection end 46 to be connected to the main body 1.

More specifically, an insertion groove 451 provided at the close end 45 of the auxiliary nozzle 4 can be fixed by an insertion portion 8 which can be fitted into the insertion groove 451. That is, as a force is applied to the auxiliary nozzle 4 in a rearward direction at the use position, the insertion portion 8 is coupled to the insertion groove 451 to restrict the rotation of the auxiliary nozzle 4 .

When the user moves backward to the auxiliary nozzle 4, the auxiliary nozzle 4 moves backward in accordance with the movement of the rotary shaft 452 accommodated in the slot 12. [ Therefore, it is preferable that the length of the long hole 12 provides a sufficient length to allow the insertion groove 451 and the insertion portion 8 to be engaged by the translation of the auxiliary nozzle 4.

On the other hand, the connection end 46 allows the insertion portion 8 to more efficiently perform the rotation restricting function of the auxiliary nozzle 4. [ There is a greater risk that the insertion portion 8 may be disengaged from the insertion groove 451 without the connecting end portion 46 extending in the longitudinal direction.

This rotation restricting structure makes the fixing of the auxiliary nozzle 4 and the main body 1 more rigid and prevents the auxiliary nozzle 4 from moving in an unpredictable manner in the process of cleaning the user.

According to an embodiment of the present invention, the rotation axis 452 may be a projection 453 formed on both sides of the connection end portion 46. In particular, the protrusion 453 may be formed on the side of the end of the connecting end portion 46. When the protrusion 453 is received in the slot 12, the auxiliary nozzle 4 is rotated or translated in the main body 1 as the protrusion 453 rotates or translates in the slot 12, can do.

FIG. 5 is a perspective view showing the combination of the auxiliary nozzle 4 and the dust brush 6 according to an embodiment of the present invention. 6 is a state of use of the dust brush 6 according to an embodiment of the present invention.

Hereinafter, the dust brush 6 according to the embodiment of the present invention will be described in more detail with reference to FIGS. 5 and 6. FIG.

The dust brush 6 is linearly moved in a state of being coupled to the auxiliary nozzle 4 and can be moved to a use position or a storage position of the dust brush 6.

That is, the dust brush 6 may also be provided in the main body 1 at all times.

The auxiliary nozzle 4 may be provided with a first locking protrusion 42 so that the dust brush 6 can be fixed to the auxiliary nozzle 4 at the use position. Also, the dust brush 6 may be provided with a latching groove into which the first latching protrusion 42 is inserted. In the use position, the first locking protrusion (42) is inserted and fixed in the locking groove.

It is preferable that the position of the first latching protrusion 42 is determined so that the dust brush 6 protrudes from the auxiliary nozzle 4 at the use position. The end of the dust brush 6 must protrude from the auxiliary union nozzle to function as a dust brush 6 for sweeping foreign matter.

In addition, a second locking protrusion 43 may be provided at the other end of the auxiliary nozzle 4. And the second latching protrusion 43 is inserted into the latching groove at the receiving position.

The dust brush 6 may be fixed to the second locking protrusion 43 and stored in the seating part 7 together with the auxiliary nozzle 4.

The position of the second locking protrusion 43 and the position of the seat cushion 43 are adjusted so that the auxiliary nozzle 4 can be housed in the seating portion 7 in a state where the locking groove is coupled to the second locking protrusion 43. [ It is preferable that the length and the width of the light source 7 are determined.

6 (a), when the user desires to use the dust brush 6, the dust brush 6 is pressed against the auxiliary nozzle 4 fixed to the second locking protrusion 43 And is rotated from the seat portion 7 to the use position.

6 (b), the user can linearly move the dust brush 6 from the second locking protrusion 43 to the first locking protrusion 42. As shown in FIG. That is, the dust brush 6 can be used by sliding the dust brush 6 from the storage position to the use position by applying an external force to the user.

The auxiliary nozzle 4 may further include a rail 41 for guiding the linear movement of the dust brush 6. According to an embodiment of the present invention, the rail 41 may be provided on the side surface of the auxiliary nozzle 4, but is not limited thereto.

The dust brush 6 can smoothly move linearly between the first engaging projection 42 and the second engaging projection 43 through the rail 41. The rail 41 prevents the dust brush 6 from being detached from the auxiliary nozzle 4 during the movement of the dust brush 6 to the use position or the storage position.

FIG. 7 shows an embodiment in which the dust brush 5 is rotatably installed in the main body 1.

The dust brush 5 may be rotatably mounted on the main body 1. [ The dust brush 5 may also include a rotating shaft 531 for directly connecting to the main body 1. The rotating shaft 531 of the dust brush 5 is accommodated in the long hole 11, (5).

Fig. 7 (a) shows a state in which the dust brush 5 is in the storage position. A position at which the dust brush 5 is seated in the seating portion 7 may be referred to as a storage position. When the dust brush 5 is not used, the dust brush 5 is stored in the storage position.

When the user wishes to use the dust brush 5 or the dust brush 5, the dust brush 5 is rotated as shown in FIG. 7 (b). Then, the dust brush 5 is rotated by the maximum rotation angle as shown in FIG. 7 (c) so as to reach the use position.

At this time, an elongated hole 11 for receiving the rotation shaft 531 is provided so that the rotation shaft 531 can rotate and translate. The long hole 11 can receive both the rotation axis 452 of the auxiliary nozzle 4 and the rotation axis 531 of the dust brush 5.

Therefore, when only the dust brush 5 is desired to be used separately, the dust brush 5 can be rotated independently of the auxiliary nozzle 4.

That is, the dust brush 5 is provided to surround a part of the outside of the auxiliary nozzle 4, so that the dust brush 5 can be relatively rotatable with respect to the auxiliary nozzle 4. Therefore, it is preferable that the dust brush 5 is opened on one side of the dust brush 5 so that the dust brush 5 can rotate independently while wrapping the auxiliary nozzle 4.

Meanwhile, the dust brush 5 may be rotated about the rotation axis 531 and stored in the seating part 7 together with the auxiliary nozzle 4.

Therefore, since the dust brush 5 is always connected to the main body 1, the risk of loss of the dust brush 5 is greatly reduced compared with the case where the dust brush 5 is separately stored.

Meanwhile, in order to use the dust brush 5 to sweep the foreign substance, it is preferable that the dust brush 5 receives rotation restriction at the use position. If the dust brush 5 is continuously moved without being fixed at the use position, external force is not efficiently transmitted to the dust brush 5 when removing the foreign substances attached to the cleaning surface, which is a serious inconvenience.

The dust brush 5 is firmly fixed from the main body 1 at the use position. The structure in which the dust brush 5 is fixed at the use position is a structure in which the auxiliary nozzle 4 is fixed Structure.

More specifically, the dust brush 5 includes a base portion 51 for sweeping dust, a close-contact end portion 52 to be in close contact with the suction nozzle, and a contact portion 52 which extends from the close contact end portion 52, And a connecting end 53 connected thereto. At this time, the rotation shaft 531 may be provided at the end of the connection end portion 53.

The close end portion 52 is a portion that engages or adheres to a part of the suction nozzle 17 when the dust brush 5 is in the use position. It is preferable that the length and shape of the close-contact end portion 52 are determined so as not to be distanced from the suction nozzle 17 at the use position.

A portion of the coherent end 52 may extend further in the longitudinal direction. According to an embodiment of the present invention, the lower end of the close end portion 52 may extend in the longitudinal direction to form the connection end portion 53. At the end of the connection end portion 53, a rotation shaft 531 for connection with the main body 1 may be formed.

Also, according to an embodiment of the present invention, the rotation axis 531 may be a protrusion formed on both sides of the end of the connection end portion 53. [ When the protrusion is received in the long hole 11, the dust brush 5 can be rotated or translated in the main body 1 as the protrusion rotates or translates in the long hole 11.

The rotary shaft 531 of the dust brush 5 may be accommodated in the long hole 11 while forming a coaxial axis with the rotary shaft 452 of the auxiliary nozzle 4. In this case, the end of the connection end portion 53 of the dust brush 5 has a width larger than that of the connection end portion 53 of the auxiliary nozzle 4, and is disposed outside the rotation axis 452 of the auxiliary nozzle 4 Can be combined.

 Therefore, since the auxiliary nozzle 4 and the dust brush 5 are always provided in the vacuum cleaner, the risk of loss can be reduced.

The dust brush 5 or the auxiliary nozzle 4 housed in the main body 1 can be moved to the used position by rotating only the dust brush 5 or the auxiliary nozzle 4, So that it is possible to reduce the inconvenience that the suction nozzle 17 is brought into engagement with the suction nozzle 17. That is, simplification of use operation is aimed at.

In addition, since the movement of the auxiliary nozzle 4 or the dust brush 5 from the main body is limited at the use position, it is possible to provide a coupling structure capable of performing cleaning more efficiently.
