The present invention relates to a vacuum cleaner, and more particularly, to clean the bottom surface of a large space when the vacuum cleaner is used or to clean the bottom surface of a relatively narrow space or a corner at a place to be cleaned. It relates to a vacuum cleaner that can perform a clean cleaning by performing the cleaning while switching the use of the cleaner.

In general, a vacuum cleaner performs cleaning while inhaling dust or dirt by a strong suction force generated by a driving motor provided in a main body.

The general configuration of such a vacuum cleaner is the same as that of FIG. That is, if it looks at its configuration, one end is connected to the main body 100 having a driving means and a dust collecting means not shown inside, the connecting means 200 provided in front of the main body 100, the connecting means 200 Installed and equipped with a grip portion 300 on the other end and the flexible connection hose 400 having a predetermined length, a plurality of connection pipes 500 are installed in connection with the grip portion 300 and configured in multiple stages, the connection The suction member 600 is detachably provided at the front of the pipe 500.

When using a conventional vacuum cleaner having such a configuration, when power is applied to a cleaning main body and operated, the driving motor (not shown) provided inside the main body 100 and functions as a driving means is driven by dust generated by the suction force generated. The dirt or the like is collected by the dust collecting means (not shown) provided inside the main body 100 via the suction member 600, the connection pipe 500, the connection hose 400, and performs cleaning.

However, the following problem occurs when using such a conventional vacuum cleaner. That is, when the vacuum cleaner is used, the user moves the suction member 600 forward and backward while holding the gripper 300 and the connecting pape 500 to suck and clean dust or dirt. Since the member 600 is generally formed in a square or circular shape, it is easy to clean the floor surface of a relatively large space, but the space of the floor surface to be cleaned is relatively narrow or the part of the wall that is in contact with the wall surface, that is, the edge of the wall surface. The bottom part in contact with the part has a problem that is difficult to clean. Therefore, the user has to turn the left and right directions when cleaning the corner area to perform the cleaning, which causes troublesome use.

Therefore, the present invention has been devised in view of the above-described general technical shortcomings, and the floor to be cleaned when cleaning the bottom of a large space or a relatively narrow space when using a vacuum cleaner It is an object of the present invention to provide a vacuum cleaner capable of performing clean cleaning by performing cleaning while selectively changing the use type of the vacuum cleaner with respect to the shape of the cotton.

A bearing 42 for guiding the smooth rotation of the suction means 50 to be described later is fitted to the outside. An annular body 43 is formed below the bearing 42 so as to have an outer diameter somewhat larger than the outer diameter of the pivot shaft 41. ) Is provided and at least two or more support grooves 44 are formed on both sides of the annular body 43 facing each other. A tooth 45 is provided below the support groove 44, that is, below the rotation shaft 41.

The suction means 50 is provided with a rectangular flow groove 52 in place on the upper surface and the upper side is fitted to be rotatable on the outside of the bearing 42 and at least one opened and closed by the opening and closing means 70 to be described later It consists of the suction member 51 which is a hollow body provided with the suction hole 53 mentioned above.

Preferably, the suction member 51 has a wide flat shape so that one side can easily clean a relatively large space, which will be described later, and the other side of the suction member 51 has a relatively narrow space or edge cleaning for the shape of the bottom surface to be cleaned. It is preferable to comprise in the shape of a polygon having a tip portion at the center portion for ease (see FIG. 2).

To this end, the suction hole 53 is composed of a pair of first and second suction holes respectively formed on the front and rear sides of the lower surface of the suction member 51.

The first suction hole (53a) is provided in front of the lower surface of the suction member 51 and configured to communicate in a polygonal shape so as to form a front end portion opposed to the suction member 51 having the polygonal shape and the The second suction hole 53b is preferably configured in a relatively rectangular shape provided on the other side of the first suction hole 53a.

The suction means 50 is changed by the direction changing means 60 in accordance with the conditions of the space to be cleaned later to perform the cleaning.

The direction changing means for satisfying this has a switch 61 provided on the upper side of the suction means 50 (or the gripping portion) as shown in FIGS. 3 to 4, and the suction means is electrically connected to the switch 61. An inner upper side of the means 50 is provided with an operating part 62 opposite to one side of the annulus 43.

In addition, the upper portion of the suction means 50 is electrically connected to the operation part 62 to correspond to the operation part 62 to be driven together when the operation part 62 is operated, and when the operation part 62 is not operated. A drive motor 63 for stopping driving is provided. A drive gear 64 engaged with the gear 45 is provided below the drive motor 63.

Preferably, the operation unit 62 is preferably configured of a solenoid 62a having an operating rod 62b that is supplied with power from the switch 61.

In addition, the opening and closing direction of the suction hole 53 provided at the lower side of the suction member 51 is determined by the opening and closing means 70.

As shown in FIGS. 4 to 5, the opening and closing means 70 includes a pair of support jaws 71 protruding from the front and rear sides of the first and second suction holes, and the left of the first and second suction holes. , A pair of guide rails protruding on the right side, the sliding member is sandwiched between the guide rails, one side is formed to face the first suction hole (53a) and has a plate-shaped opening and closing member 73 having a slightly larger tip portion, The upper and lower ends of the opening / closing member 73 are supported, and the other end is composed of an operation period 74 exposed to the outside through the flow groove 52 provided on the upper side of the suction member 51.

The operation period 74 is a control lever 74a partially exposed to the outside of the flow groove 52 of the suction member 51, one end is integrally coupled to the lower side of the control lever 74a and approximately both sides of the central part. A tubular body 74c rotatably arranged inside the suction member 51 by the hinge shaft 74b, an elastic member 74d provided inside the tubular body 74c, and an inner side of the tubular body 74c. One end portion is inserted and supported by the elastic restoring force of the elastic member (74d) so that the other end is connected to the upper surface of the opening and closing member (73) is composed of a retreat rod (74e).

The operation of the present invention having such a configuration will be described.

When the vacuum cleaner is operated for the first time, a suction motor 51 which is provided inside the main body 10 and drives a driving motor (not shown) which performs a function of a driving means and performs a function of the suction means 50 as in the related art. ) Suction power is generated.

In addition, at this time, the operating rod 62b of the solenoid 62a which performs the function of the operating unit 62 is inserted into and supported in the support groove 44 provided at one side of the annular body 43 so as to support the suction member 51. Control lever 74a protruding outward of the flow groove 52 of the suction member 51 is completely inclined to one side of the flow groove 52, and the retreat rod 74e is opened and closed. It is in a state in which 73 is biased to one side, that is, only the first suction hole 53a is completely closed and only the second suction hole 53b is opened.

Therefore, this state becomes a state which performs cleaning of a wall surface (or the floor surface with a little dirt etc.).

In this state, the rectangular second suction hole 53b side, that is, one side having a flat plate shape of the suction member 51 will be located in the front side (or rear side) with respect to the cleaner body 10.

In this state, when a large amount of dirt or dust is to be cleaned, that is, when the bottom surface of a relatively large space is to be cleaned, the control lever 74a is positioned at an approximately central portion with respect to the flow groove 52.

Therefore, at this time, the operating rod 74 is rotated around the hinge shaft 74b provided in an approximately central portion of the operating rod 74 and rotatably arranged on both sides of the suction member 51. Therefore, the elastic member 74d installed inside the tubular body 74c is compressed by the forward and backward rod 74e, and the opening and closing member 73 is positioned between the first and second suction holes after moving between the guide rails 72. Open both the first and second suction holes.

Therefore, at this time, the first and second suction holes are used to clean the floor of a relatively large space with a lot of dirt or dust.

In addition, in this state, when cleaning a relatively narrow space or a corner bottom, if the control lever 74a is completely flipped to the other side of the flow groove 52 in the reverse order, the operation period 74 is centered on the hinge shaft 74b. It rotates and the elastic member 74d is extended. Therefore, the advance and exit rod 74e moves the opening and closing member 73 toward the second suction hole 53b so that the second suction hole 53b is closed and only the first suction hole 53a is opened. When the switch 61 provided on the upper side (or the gripping part side) of the suction member 51 is operated, power is supplied to the operating part 62 and inserted into the support groove 44 of the annular 43. The operating rod 62b of the solenoid 62a, which has been previously removed from the support groove 44, is simultaneously supplied with power to the driving motor 63 to drive the driving motor 63. Therefore, the operating rod 62b is at this time. The drive motor 63 is continuously contacted with the outer circumferential surface of the annular body 43 and attached to the inside of the suction member 51 in a state where the support groove 44 is separated from the support groove 44. ), The drive gear 64 is arranged in the state of being engaged with the gear provided on the lower side of the rotating shaft 41 to support the rotating shaft 41. That is, the rotation shaft 41 is interlocked in the state in which only the drive gear 64 is engaged along one direction of the gear provided on the lower side of the rotation shaft 41 in a fixed state.

Of course, at this time, the working rod 62b of the solenoid 62a attached to the suction member 51 side at the position opposite to the driving motor 63 also moves the outer peripheral surface of the ring 43 as the suction member 51 rotates. 6, therefore, rotate with me.

When the driving motor 63 and the solenoid 62a are rotated 180 degrees together with the suction member 51, the operating rod 62b is inserted into and supported in the support groove 44 on the other side and simultaneously moves to the operating rod 62b. The power that was supplied is cut off and thus the power that was supplied to the drive motor 63 is also cut off and the power supply to the drive motor 63 is cut off.

Therefore, at this time, one side having the front end of the suction member 51 with respect to the vacuum cleaning main body 10 is located in front to facilitate the cleaning of the corner portion by the suction force of the first suction hole (53a).

7 is a perspective view of another embodiment of the present invention. Another embodiment of the present invention is to invert the front and rear of the suction means by inclined toward the front of the suction means while the cleaning pipe is pushed in the inclined toward the rear of the suction means. That is, the upper and the rear of the suction means 50 is formed in the lower end of the passage 80 having an arc shape, the rail 81 formed inside the opposite surface of the passage 80, the connection pipe 30 A cover 82 for moving the passage 80 along the 81 is provided.

8 (a) (b) is a cross-sectional view of another embodiment of the present invention. That is, the holder 84 is inserted into the connection pipe 30 to the lower end of the gripping portion 21, a hole 85 formed in the front and rear of the holder 84, and formed in front of the upper end of the connection pipe 30 and the holder ( In the state of being fitted into 84, a button 83 that is engaged in the hole 85 is provided. Here, the button 83 is applied to the hole 85 in the direction in which the force is applied. In other words, unless the external force is applied, the button 83 is caught in the hole 85 and the button 83 is pushed out of the hole 85.

Another embodiment of the present invention configured as described above is moved onto the passage 80 in a state of being fitted to the cover 82 and the rail 81 of the connection pipe 30. That is, when cleaning the corners, the connecting pipe 30 is inclined toward the rear side of the suction means 50 as shown in FIG. At this time, the first suction hole (53a) is formed in a corner of the front of the suction means (50). Therefore, it is possible to clean the corners by pushing the connection pipe 30 in this state.

In addition, when the connecting pipe 30 is rotated to the front of the suction means 50 like the virtual line, it is possible to clean a large space. That is, while rotating the connection pipe 30, pressing the button 83 to rotate the holding portion 21 by 180 degrees. At this time, the button 83 is fitted from the front hole 85 of the holder 84 to the rear hole 85. When pushing the connection pipe 30 in this state, the dust is sucked through the second suction hole (53b) of the suction means (50). On the other hand, when the connection pipe 30 is used in the same state as the solid line, the control member 74a of the opening and closing means 70 is rotated forward to block the second suction hole 53b, and when the connection pipe 30 is used in the same state as the virtual line, the rear side is used. It is used to rotate so that the first suction hole 53a is blocked.

As described in detail above, the present invention uses the vacuum cleaner according to the shape of the bottom surface to be cleaned when cleaning the bottom surface of a large space or a relatively narrow space or a corner when using the vacuum cleaner. It is possible to perform a clean cleaning by performing the cleaning by switching the form selectively.
