Abstract

PURPOSE:To efficiently clean both the floor surfaces of a carpet and a mat or a bare board floor by installing a auction pipe so as to be freely rotatable to a nozzle main body in which plural lines of suction bodies whose cross section is a ship shape, formed by a soft material, are arranged on the bottom face of a nozzle. CONSTITUTION:As for the carpet floor surface, especially, the carpet floor whose hair foot is long, a suction body 11 is moved in a longitudinal direction. Accordingly, the tip part of the suction body 11 pushes aside the hair feet and moves, thus resistance by the hair feet is small and cleaning is executed easily. On the other hand, as for a bare board floor and a mat floor, a nozzle 10 is moved in the side direction of the suction body 11. In this case, since the width of the nozzle 10 is wide and the arrangement of the suction body 11 also has no dead angle, the efficiency of cleaning is improved. Also, since the auction body 11 is formed by a soft material, the suction body 11 does not damage the floor surfaces of the mat and the board.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle for a vacuum cleaner.

0002

[Prior Art] Research has progressed over many years regarding the nozzles used in vacuum cleaners, and now nozzles with different structures are used to suit the specifications of each floor, such as wooden floors, tatami floors, or carpeted floors. It is configured.

[0003] Among various types of floors, carpet floors have piles, so dirt and hair are particularly likely to adhere to them, and it is difficult to remove them. Recently, carpets with particularly long piles have become popular in households, but it is extremely difficult to collect the dirt that accumulates at the base of the long piles with a regular vacuum cleaner nozzle, so a special Nozzles have also been developed. Figure 5
is a cross-sectional view of a vacuum cleaner developed for cleaning long-pile carpets, Fig. 6 is a partially enlarged view, and Fig. 7 is an enlarged view of the protrusion. In the figure, 1 is the vacuum cleaner and 2 is the nozzle. , 3 is hole 3
4 is a rotating brush, 5 is a dust collection bag, 6 is a protrusion with a hole in it;
is the airflow, 7 is the carpet, and 7a is its pile. This vacuum cleaner has a nozzle 2 with a large number of protrusions 3 arranged orthogonally to the moving direction of the nozzle. When cleaning a carpet with long piles 7a, the tips of the protrusions 3 are
The purpose is to reach the root of the bristles 7a and collect dirt and the like by suctioning through the hole 3a.

0004

[Problems to be Solved by the Invention] When cleaning is attempted using the nozzle provided with the projection, the long bristles 7a of the carpet come into contact with the projection 3 disposed on the nozzle 2, causing the nozzle 2 to bulge. This creates a large resistance to movement, making it extremely difficult to move the nozzle 2, and effectively causing the nozzle 2 to move.
It is impossible to clean while pushing and moving.

[0005] Furthermore, when this nozzle 2 is used on a floor other than a carpet, such as between boards, since the intervals between the protrusions 3 are wide, the dirt between the protrusions 3 will not be collected, and the dust will not be collected on the floor. To completely clean a surface, the nozzle must be moved over and over again to the same location, which is time-consuming. Furthermore, if the protrusions are made of a hard material, there is a risk of damaging the folds or between the boards.

The present invention has been made to solve the above-mentioned problems of conventional vacuum cleaners, and can efficiently clean not only long-pile carpet floors but also spaces between boards and folded floors.
To provide a vacuum cleaner nozzle that does not damage folds or between boards.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the nozzle of a vacuum cleaner according to the present invention has a nozzle body having a plurality of rows of suction bodies formed from a soft material and having a boat-shaped cross section arranged on the bottom surface of the nozzle. The suction pipe is rotatably attached to the top.

[0008]

[Operation] When cleaning using the nozzle of the vacuum cleaner mentioned above, when cleaning a carpeted floor, the direction of movement of the nozzle is the longitudinal direction of the suction body, which has a boat-shaped cross section; when cleaning between folded floors or boards, The direction of movement of the nozzle is the lateral direction of the suction body. As a result, when cleaning a carpet floor, the tapered part of the suction body moves through the carpet's bristles, so there is no resistance to the movement of the nozzle, and cleaning is performed smoothly.

In addition, when cleaning between folds or boards, the nozzle is moved in the lateral direction of the suction body, but since there is no bristles, it does not get in the way of the nozzle movement, and the cleaning range is wide in one nozzle movement, making cleaning easier. Increased efficiency. Furthermore, since the suction body is made of a soft material, the suction body will not damage the folds or between the boards.

[Embodiment] Fig. 1 is a partial sectional side view of a nozzle of a vacuum cleaner showing an embodiment of the present invention, Fig. 2 is a rear view thereof, and Fig. 3 is a perspective view of the nozzle when cleaning between folds and boards. FIG. 4 is a perspective view of the nozzle used when cleaning a carpet, in which 10 is the nozzle body, 11 is a boat-shaped suction body, 12 is its air suction hole,
13 is a suction pipe, 14 is a joint between the suction pipe and the nozzle body, 15 is a longitudinal direction of the suction body, and 16 is a lateral direction of the suction body.

As shown in FIG. 2, on the back side of the nozzle body 10, suction bodies 11 made of a soft material such as rubber and having air suction holes 12 are arranged in a staggered manner in multiple rows. The suction body 11 has a boat-shaped cross section with both ends tapered in the longitudinal direction. Furthermore, in the arrangement of the suction bodies 11, when moving the nozzles in the lateral direction 16 of the suction bodies 11, care is taken to ensure that there are no spots (blind spots) on the floor surface where suction leaks from the air suction holes 12. Further, a suction pipe 13 is rotatably attached to the central part of the back surface of the nozzle body 10 via a joint 14.

When cleaning a carpet floor using a vacuum cleaner equipped with the above nozzle, the nozzle is moved in the longitudinal direction 15 of the suction body 11, as shown in FIG. Further, when cleaning between boards or on a folded floor, the suction pipe 13 is rotated relative to the nozzle body 10 to move the nozzle in the lateral direction 16 of the suction body 11, as shown in FIG.

[0013] For carpet floors, especially carpet floors with long piles, since the suction body 11 is moved in the longitudinal direction 15, the tapered part of the suction body 11 separates the piles and moves, reducing the resistance due to the piles. Cleaning is easy. Furthermore, when cleaning between boards or on a folded floor, the nozzle is moved in the lateral direction 16 of the suction body 11, but the cleaning efficiency is improved because the nozzle is wide and the suction body 11 is arranged without any blind spots. In addition, since the suction body 11 is made of a soft material, the suction body 11 will not damage the floor surface of the folding or board.

In this embodiment, the suction bodies 11 having the same specifications are arranged in a staggered manner on the back surface of the nozzle body 10, but the arrangement of the suction bodies 11 is not limited to this example; for example, the suction bodies 11 may have different specifications. The suction bodies 11 may be arranged randomly. However, in consideration of cleaning carpets with long piles, the suction bodies 11 each having a boat-shaped cross section must be arranged with their axes parallel to each other. Further, when moving the suction body 11 in the lateral direction 16, it is desirable that the arrangement be such that no part of the suction leakage is left on the floor surface.

[0015]

[Effects of the Invention] The vacuum cleaner nozzle according to the present invention has a suction pipe rotatably attached to the nozzle body, which has a plurality of rows of suction bodies formed of a soft material and having a boat-shaped cross section arranged on the bottom surface. As a result of this structure, the following excellent effects were achieved.

(1) By changing the direction of movement of the nozzle, it is possible to efficiently clean both the floor surfaces, including carpets and spaces between folds and boards.

(2) Since the suction body is made of a soft material, the suction body will not damage the folds or between the plates.
