Description

Structure for connecting dust-envelope in vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a dust collecting bag coupling structure of a dust collecting bag for collecting various foreign substances sucked into the inside of the vacuum cleaner so that a smooth coupling can be made in the inside of the vacuum cleaner. It is about.

Generally, a vacuum cleaner is mainly used for cleaning corners and other places where general brooms or other cleaning tools are difficult to clean in a house, a car, or other places. It is a device to remove foreign substances.

Such a vacuum cleaner has a main body 10 in which an insertion hole 11 is formed to communicate with the inside of the vacuum cleaner as shown in FIGS. 1 and 2, and an intake body connected to the main body to suck air and various foreign substances in the room ( 20).

At this time, the suction hose 31, the handle portion 32, the extension tube 33 and the like are sequentially connected between the suction inlet body and the main body, the suction hose through the insertion hole 11 formed in the main body Is connected to the inside of the dust collecting bag 12 provided therein.

Therefore, the various foreign substances sucked through the suction port 20 are sequentially passed through the extension tube, the handle portion, the suction hose, and the like into the dust collecting bag 12 in the main body through the insertion hole 11 formed in the main body 10. Inflow.

Various foreign matters may be sucked into the main body as the fan 14 rotates to generate a suction force by the driving force of the motor 13 provided in the main body 10, and the dust is sucked into the main body and collected. Various air passing through the bag 12 is discharged to the room through a plurality of discharge holes 15 formed in the back of the main body 10.

On the other hand, the dust collecting bag 12 of each component of the above-described vacuum cleaner should always be replaced before the various foreign matters collected to exceed the proper allowable capacity.

Accordingly, the dust bag as described above is configured to be removable from the body (10).

That is, the coupling guide 16 is bent in the vicinity of the insertion hole 11 in the vacuum cleaner body 10, and the dust collecting bag 12 is guided by the coupling guide to be in close contact with the inside of the main body 10. As the communication hole 12b is formed and the coupling plate 12a for introducing air and various foreign matters sucked from the outside into the dust collecting bag is integrated, as described above, the main body 10 and the dust collecting bag 12 are mutually separated. Can be combined and removed.

In addition, the outer periphery of the insertion hole is formed with a rubber leakage prevention film 17 to seal the gap between the insertion hole 11 and the dust collecting bag 12, the air introduced through the suction hose 31 and various foreign matters To prevent external leakage.

However, the combination of the dust bag and the inside of the main body as described above has caused various problems as described later due to the shape characteristics of each other.

First, the gap between the inner wall of the main body and the inner surface of the coupling guide is almost the same as the thickness of the coupling plate of the dust collecting bag, it was difficult to smoothly mutually connect.

This, in turn, has a problem that the user's attention is required to increase the user's dissatisfaction.

Secondly, in the process of inserting the binding plate of the dust collecting bag into the coupling guide formed on the main body to couple the dust collecting bag to the inside of the body, the coupling plate and the inner surface of the main body are formed in the insertion hole in the main body as they slide. The end of the bonding plate is caught by the leak prevention film to turn over the leak prevention film.

This means that the leakage preventing film is easily made upside down when the coupling plate is continuously moved downward in the state of being caught by the leak preventing film, considering that the leakage preventing film is made of a flexible material rubber.

Accordingly, the leak prevention film is not exactly fitted into the communication hole of the dust collecting bag, and a gap is formed between the air and various foreign substances introduced through the suction hose, and thus, through the insertion hole, the leakage preventing film is introduced into the communication hole of the dust collecting bag. As the leak occurred through the gap generated together, the cleaning efficiency was drastically reduced.

The present invention has been made in order to solve the above-mentioned conventional problems, in the process of coupling the dust collecting bag inside the cleaner body to facilitate the mutual coupling at the same time the leakage preventing film formed in the insertion hole in the main body dust collecting bag The purpose is to be able to closely adhere to the communication hole of the to prevent external leakage of air and various foreign substances sucked during cleaning.

According to an aspect of the present invention for achieving the above object, the insertion hole is formed in the main body and the air and various foreign substances are sucked in, the coupling guide bent on the inner wall of the main body along the circumference of the insertion hole in the main body, and the coupling guide In the vacuum cleaner having a coupling plate which is guided by a close contact with the inner wall surface of the main body in which the insertion hole is formed, and a dust collecting bag which is connected to the insertion hole of the main body to collect various foreign substances in a state integrated with the coupling plate, wherein the coupling plate A protruding portion formed at an upper end of the protruding toward both sides, a bent portion extending at an upper end of the coupling guide and inserted into the protruding portion of the joining plate, and protruding to an inner surface of the extended bent portion to form a stone of the joining plate. A first protrusion for adhering the part to the inner wall surface of the cleaner body, and a protrusion formed at an inner side surface of the lower end of the coupling guide so that the lower end of the coupling plate Provided is a dust collecting bag coupling structure of a vacuum cleaner, characterized in that it comprises a second protrusion in close contact with the inner wall surface of the cleaner body.

Figure 4 is a perspective view of the main part showing a state in which the main body and the dust collecting bag of the vacuum cleaner according to the present invention is coupled, Figure 5 is a perspective view of the main part showing a state seen from the back of Figure 4, with reference to this one of the present invention Hereinafter, the configuration according to the embodiment will be described in more detail.

First, the present invention extends the protrusion 121a protruding toward both sides at the upper end of the coupling plate 121 integrated in the dust collecting bag 120, and the coupling guide 160 formed on the wall surface of the main body 100. The upper end of the bending portion 161 is inserted into the protrusion of the coupling plate is formed.

In this case, the coupling guide forms a wider space (H) between the inner wall surface of the body and the inner surface of the coupling guide than the conventional coupling guide.

The dimension of the space H between the inner wall surface of the main body and the inner surface of the coupling guide is not particularly limited, but it is more preferable to form the gap so as to form about twice the thickness t of the coupling plate 121.

In addition, the inner side of the extended bent portion 161 protrudes to form a first protrusion 162 for closely contacting the protrusion 121a of the coupling plate 121 to the inner wall surface of the cleaner body 100, the coupling guide On the inner side of the lower end of the coupling plate 121 protrudes to form a second projection 163 to be in close contact with the inner wall surface of the cleaner body 100.

The protrusion distance d of each protrusion 162 and 163 is approximately the distance excluding the thickness t of the coupling plate among the gaps H between the inner surface of the coupling guide 160 and the inner wall surface of the main body 100. It is preferable to configure it, and it is not necessary to exactly fit these dimensions.

At this time, the first and second protrusions are formed to be curved toward the inner wall surface of the cleaner body 100 gradually toward the lower side in the main body, which is a dust collecting bag (162, 163) as described above When the coupling plate 121 is in contact with the integrated body 120 is to be in close contact with the inner wall surface of the cleaner body 100, the contact portion of the coupling plate.

In addition, the position of the second protrusion is preferably formed to be located at a lower side than at least the position where the leakage preventing film 17 is formed, which is, during the process of inserting the coupling plate 121 into the coupling guide 160 The bottom of the coupling plate is to be able to be inserted smoothly without being caught by the leak-proof film (17).

The shape of each projection 162, 163 for performing such a function is not limited to the curved shape.

That is, although not shown, the projections may be formed to be inclined toward the inner wall surface of the cleaner body gradually toward the lower side of the main body, or may be embodied at the same time as the inclined and curved shapes.

However, when the shape of each of the protrusions 162 and 163 is formed to be curved as in the embodiment of the present invention, when the coupling plate 121 is completely coupled to the inside of the coupling guide 160, the coupling plate is formed in each protrusion ( 162, 163 can be exactly in close contact with the inner wall surface of the main body 100 and the stable support is possible can achieve a more desirable form.

Such a configuration of the present invention will be described in more detail with reference to FIGS. 6A and 6B illustrating a process of combining the dust collecting bag into the vacuum cleaner body.

First, in order to couple the dust collecting bag 120 into the main body 100, the coupling plate 121 integrally formed with the dust collecting bag is inserted into the coupling guide 160 bent in the main body 100.

Insertion of the coupling plate is made by first inserting the lower end of the coupling plate 121 on the upper end of the coupling guide 160 and then moving downward. 121) the width (gap between the inner surface of the coupling guide and the vacuum of the body; H) and the width ( ) And the thickness (t) and bottom width ( As it is formed wider than) etc., it can be understood that the smooth insertion can be achieved.

In addition, as the coupling plate 121 continues to move downward as described above, the lower end of the coupling plate 121 is integrated into an appropriate depth, that is, the main body 100, as shown in FIG. 6A. When the leak-proof film 17 is inserted to the depth that passes through the position where it is located is guided by the second projection 163 formed on the lower inner wall surface of the coupling guide gradually moves toward the front side inside the main body 100. .

At this time, the protrusions 121a formed on both sides of the upper end of the coupling plate 121 are inserted into the bent portion 161 formed at the upper end of the coupling guide 160 and at the same time, the first portions formed on the inner side of the bent portion. Guided by the projection 162 is gradually moved toward the front side inside the main body 100.

Therefore, when the complete coupling of the coupling plate 121 is completed, the front surface of the coupling plate is in close contact with the inner wall surface of the main body 100 as shown in Figure 6b and at the same time the communication hole 122 formed in the coupling plate The leak prevention film 17 is fitted correctly.

This is because, as the coupling plate 121 inserted into the coupling guide 160 by the first protrusion 162 and the second protrusion 163 is gradually advanced, the communication hole 122 and the leakage preventing film 17 may be separated from each other. It is understood that the coupling can be made precisely.

In addition, the first protrusion 162 and the second protrusion 163 as described above are formed to be curved toward the lower end so that the coupling plate 121 can slide smoothly on the curved surface. At the same time, when the coupling plate is completely coupled to the inside of the coupling guide, it also plays a role of support for continuously maintaining the pushed state so that the upper and lower portions of the coupling plate closely contact the inner wall surface of the main body 100.

On the other hand, when removing the coupling plate 121 from the coupling guide 160 for the replacement of the dust collecting bag 120 may be performed in the opposite operation to the above-described insertion process, which is easily understood, so a detailed description thereof will be omitted. Do it.

As a result, by the configuration of the present invention as described above, the user can easily achieve the combination and removal of the dust collecting bag.

As described above, the structure for coupling the dust collecting bag of the vacuum cleaner according to the present invention enables seamless coupling even without the user paying close attention.

In addition, as the coupling plate of the dust collecting bag is formed to be in close contact with the main body in a predetermined portion inserted into the coupling guide, the phenomenon that the leakage preventing film is reversed by the coupling plate can be prevented in advance, and at the same time, the coupling plate. The coupling between the communication hole formed in the leak prevention film can be made smoothly and there is also an effect that can prevent the external leakage of air and various foreign matter sucked into the body.
