The extension pipe 70 may be a rigid pipe, and a passage (not shown) for guiding air may be formed therein. The suction nozzle (60) and the extension pipe (70) can be rotatably coupled to each other.

The connection pipe 80 has a passage (not shown) for guiding air therein, and is connected to the extension pipe 70 and the main body 10. The extension pipe 70 and the connection pipe 80 may be integrally formed or may be separately formed and assembled.

The extension tube assembly 50 and the main body 10 can be rotatably coupled by the hinge portions 30, Thus, the vacuum cleaner 1 has a shape with two legs and the load of the main body 10 and the load of the extension tube assembly 50 are transmitted to the wheel 42 of the main body 10 and the extension tube assembly 50 The suction nozzle 60 can be supported on the ground.

Therefore, the user does not have to apply force to support the weight of the vacuum cleaner 1 in addition to the operating force for operating the handle 100 to select the position of the suction nozzle 60. [ Therefore, the usability of the user can be increased.

The hinge portions 30 and 90 of the vacuum cleaner according to the embodiment of the present invention include guide ducts for guiding the air of the extension pipe assembly 50 to the main body 10. As a result, the appearance becomes simple, and there is no obstacle in cleaning, so that the usability can be increased.

5 is an exploded perspective view for explaining a coupling structure of an extension pipe assembly and a main body of the vacuum cleaner of FIG. 6 is a plan view of the vacuum cleaner of FIG. FIG. 7 is a cross-sectional view of the 'A' portion of FIG. 4 to illustrate the coupling structure of the extension tube assembly and the main body of the vacuum cleaner of FIG. 1; FIG. 8 is a cross-sectional view illustrating another embodiment of the coupling structure of the extension pipe assembly and the main body of the vacuum cleaner of FIG. 1;

The extension tube assembly 50 and the hinge portions 30 and 90 for rotatably coupling the main body 10 are provided with a main body hinge portion 30 provided on the main body 10 and an extension tube hinge portion 30 provided on the extension tube assembly 50. [ (90).

The main body hinge portion 30 and the extension tube hinge portion 90 may each have a substantially cylindrical shape. The main body hinge portion 30 and the extension tube hinge portion 90 can be disposed adjacent to each other in the axial direction.

The extension pipe hinge portion 90 includes an axially protruding hinge shaft portion 91 and the main body hinge portion 30 may include a hinge shaft receiving portion 31 in which the hinge shaft portion 91 is received. Therefore, by inserting the hinge shaft portion 91 into the hinge shaft receiving portion 31, the extension pipe hinge portion 90 and the body hinge portion 30 can be rotatably engaged with each other.

The hinge shaft portion 91 is provided on the extension pipe hinge portion 90 and the hinge shaft receiving portion 31 is provided on the body hinge portion 30. The present invention is not limited thereto, It is natural that there is no relation.

The extension pipe hinge portion 90 and support members 121 and 122 for supporting the extension pipe hinge portion 90 and the main body hinge portion 30 so as not to be separated may be provided outside the main body hinge portion 30. [ The support member 121 may be fixed to the connection pipe 80 and the support member 122 may be fixed to the upper body 20. [

The vacuum cleaner 1 may have a connection hose 110 for guiding the air of the extension pipe assembly 50 to the main body 10. The connection hose 110 passes through the extension pipe hinge 90, (I.e., the upper body 20).

The extension pipe hinge portion 90 includes a hose accommodating portion 92 for accommodating the connection hose 110 and a hose accommodating portion 92 for connecting the hose accommodating portion 92 to the circumferential surface of the extension pipe hinge portion 90, (Not shown).

The main body 10, that is, the upper body 20 may be provided with an inlet 230 through which the connecting hose 110 is inserted into a curved surface corresponding to the circumferential surface of the extended tube hinge portion 90.

In this configuration, the air of the extension tube assembly 50 can be guided to the main body 10 through the extension tube hinge 90.

As another embodiment in which air of the extension tube assembly 50 flows into the main body 10 through the hinge portions 30 and 90 as shown in Figure 8, A channel 296 may be provided and a second channel 236 communicating with the first channel 296 may be provided on the main body hinge portion 230.

The first channel 296 and the second channel 236 may communicate with each other through an extension pipe hinge portion 290 and an axial coupling portion of the main body hinge portion 230. Here, the shaft coupling means a hinge shaft portion 291 of the extension pipe hinge portion 290 and a hinge shaft receiving portion 231 of the main body hinge portion 230.

 That is, the outlet 297 of the first channel 296 may be formed in the hinge shaft 291, and the inlet 237 of the second channel 236 may be formed in the hinge shaft receiving portion 231.

With this structure, even if the hinge shaft 291 and the hinge shaft receiving portion 231 rotate, the first channel 296 and the second channel 236 are directly connected to each other, (10).

9 and 10 are views for explaining the operation of the vacuum cleaner of FIG. The operation of the vacuum cleaner according to the embodiment of the present invention will be described with reference to FIGS.

The extension tube assembly 50 of the vacuum cleaner and the main body 10 can mutually rotate so that the angle? Between them changes between the minimum angle? 1 and the maximum angle? 2.

It is possible to minimize the area occupied by the vacuum cleaner so that the angle &thetas; becomes the minimum angle &thetas; 1 during storage of the vacuum cleaner.

During use of the vacuum cleaner, the extension tube assembly 50 and the main body 10 can rotate mutually so that the angle? Is repeatedly increased or decreased between the minimum angle? 1 and the maximum angle? 2.

In particular, when the user wishes to advance the suction nozzle 60, the user can press the handle 100 downward in the direction of gravity so that the user can advance the suction nozzle 60 with a small force.

When the user applies an operation force to the handle 100 when the user wishes to move the suction nozzle 60 backward, the body 10 is stretched by the elastic force of an elastic member (not shown) provided on the body 10, The suction nozzle 60 can be retracted. Therefore, the used nozzle can also move the suction nozzle 60 backward with a small force.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as disclosed to the person skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
