DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-collecting bag mounting structure for a vacuum cleaner, which can replace only a bag formed of a gas-permeable material such as paper or nonwoven fabric.

[0002]

2. Description of the Related Art Conventionally, a dust collecting bag 10 of a vacuum cleaner is shown in FIG.
As shown in the figure, a paper bag 30 whose periphery is sealed is formed integrally on the back side of the cardboard bag support plate 20 in which the dust suction port 20a is formed. I was

As shown in FIG. 6, the dust collecting bag 10 is formed by fitting a bag supporting plate 20 into receiving portions 8a and 8b provided on a suction port 8d side inside the vacuum cleaner 8, thereby forming the vacuum cleaner 8 with the dust collecting bag 10.
A device which sucks air from the rear side of the air-permeable bag body 30 and sucks dust and dirt sucked together with air from the suction port 8d side of the vacuum cleaner 8 into the bag body 30. Met.

[0004]

In the above-mentioned dust collecting bag of the conventional vacuum cleaner, a cardboard bag supporting plate is integrally joined to attach a paper bag to a predetermined position inside the vacuum cleaner. And was formed. Therefore, there is a problem that the assembling is troublesome and the bag supporting plate discarded together with the bag is wasted.

Further, since the shape and size of the bag support plate vary depending on the manufacturer and model of the vacuum cleaner, it is necessary to purchase a dust collection bag corresponding to the vacuum cleaner to be used.
There was also a problem that it could not be used.

[0006] It is an object of the present invention to solve the problems of the conventional dust collecting bag of the vacuum cleaner.

[0007]

According to the present invention, there is provided a dust bag in which a plurality of folded pieces are formed by notches provided at predetermined positions on the front surface of a bag body made of a material having air permeability.
The two plate members formed with the dust suction ports are configured to be able to be joined to each other, and comprise an adapter that can be engaged with the receiving portion in the vacuum cleaner, each folded piece is folded up outside the dust collection bag, and the adapter Each of the folded pieces is passed through the outside of one of the dust suction ports, and each of the folded pieces that are folded back around the dust suction port is held between the two plates of the adapter, and the dust collection bag is attached to the adapter. This problem is solved by engaging the adapter with a receiving portion provided in the vacuum cleaner so that the dust bag is loaded into the vacuum cleaner.

[0008]

The folded piece formed on the dust collecting bag is turned outwardly of the dust collecting bag to form an opening serving as a dust suction port in the dust collecting bag, and also between the pair of plate members of the adapter. And acts as an attachment piece for attaching the dust bag to the adapter.

The adapter engages with a receiving portion provided in the vacuum cleaner, and functions as a bag support plate for loading the held dust bag into the vacuum cleaner.

FIG. 1 is a perspective view of a dust bag used in the structure for mounting the dust bag of the electric vacuum cleaner according to the present invention. This dust collecting bag 1 is formed by cutting a substantially cross-shaped cut 3 on the front surface of a bag 2 formed in a closed bag shape from a material such as paper, nonwoven fabric, or cloth having air permeability. Four folded pieces 4 that can be folded outward are formed.

FIG. 2 shows an adapter 5 which holds the dust collecting bag 1 and engages with a receiving portion in the vacuum cleaner. As shown in the figure, this adapter 5 connects two plate members 6 and 7 having substantially the same shape on which dust suction ports 6a and 7a are formed so as to be openable and closable on one side so that inner surfaces thereof can be joined to each other. It was done. Also, on one inner surface of the plate member 7,
Four protrusions 7b are provided at equal intervals with the dust suction port 7a interposed therebetween, and the same number of fitting holes 6b into which the protrusions 7b fit are formed on the inner surface of the other plate member 6.

It is assumed that the size and shape of the adapter 5 are formed so as to be compatible with the attached vacuum cleaner. Further, the plate material may be formed using cardboard or plywood which is hardly deformed. However, it is more preferable to use a synthetic resin since the projections and the fitting holes can be integrally formed.

Next, the attachment of the dust bag 1 to the adapter 5 will be described. First, each folded piece 4 of the dust bag 1 is folded out of the dust bag 1 and each folded piece 4 is attached to the adapter 5. One of the plate members 6 is passed through the dust suction port 6a from the outside, and is folded back to the periphery of the dust suction port 6a in an expanded state. Then adapter 5
The other plate member 7 is rotated and pressed in a direction in which the inner surfaces of both plate members 6 and 7 are joined to close each other. As a result, the protrusion 7b provided on the plate member 7 penetrates the folded piece 4,
It fits into the fitting hole 6b. Therefore, the dust bag 1 is attached to the adapter 5 with the dust inlet 1a opened as shown in FIG. In addition, a hole through which the protrusion 7b penetrates may be formed in the folded piece 4 in advance.

Thus, the dust bag 1 is connected to the adapter 5.
Then, when the adapter 5 is engaged with the receiving portions 8a and 8b provided inside the vacuum cleaner 8, the dust collecting bag 1 has the suction port of the vacuum cleaner 8 as shown in FIG. 8d
Is loaded into the vacuum cleaner 8 in a state of communicating with.

Accordingly, when air in the vacuum cleaner 8 is sucked by a suction fan (not shown) provided behind the dust bag 1 loaded in the vacuum cleaner 8, the suction port 8 of the vacuum cleaner 8 is opened.
Dust is sucked into the dust bag 1 together with air through a duct (not shown) connected to d. Then, after the dust that cannot pass through the eyes of the dust bag 1 is captured, only the air passes through the air-permeable dust bag 1 and is exhausted to the outside from the rear of the vacuum cleaner 8. In this way, dust collection is performed in exactly the same manner as in a conventional vacuum cleaner using a paper dust bag.

When the dust bag 1 is full, the upper lid 8c of the vacuum cleaner 8 is opened to take out the dust bag 1 loaded therein together with the adapter 5, and then the adapter 5
And the dust bag 1 may be disengaged and only the dust bag 1 may be discarded.

As described above, in the dust collecting bag mounting structure of the vacuum cleaner according to the present invention, only the dust collecting bag 1 formed of a permeable paper material is replaced, and this dust collecting bag 1 is replaced with the vacuum cleaner 8.
The adapter 5 serving as a bag supporting plate for loading and holding the predetermined position in the inside is repeatedly used.

In the embodiment, an example is shown in which a notch 3 is formed in a cross shape on the surface of the bag body 2 to form four folded pieces 4, but each folded piece 4 is located outside the dust collecting bag 1. What is necessary is just to be formed so that it may be folded, and the shape and the number are not limited to those illustrated.

[0019]

As described above, in the dust collecting bag mounting structure for a vacuum cleaner according to the present invention, the dust collecting bag is loaded into a predetermined position in the vacuum cleaner via a detachable adapter, so that the conventional structure is not used. There is no need for a cardboard or synthetic resin bag support plate that is integrally joined to the bag and discarded with the bag. Therefore, while helping to conserve resources, material costs are reduced, and the manufacturing process is simplified, so that the cost of disposable dust collection bags is reduced.

In the dust collecting bag mounting structure for a vacuum cleaner according to the present invention, if an adapter suitable for the vacuum cleaner to be used is prepared, the bag itself serving as the dust collecting bag can be used for various vacuum cleaners. Because of this excellent model compatibility, it is not necessary to produce different dust collection bags for each model as in the past, reducing costs by mass production and making it easier to obtain dust collection bags. There are many excellent effects that have not been seen in the past, such that convenience is achieved.
