2. Description of the Related Art Conventionally, various dust collecting bags having various shapes have been developed as a dust collecting bag capable of capturing dust sucked by an electric vacuum cleaner. A conventionally used dust-collecting bag is composed of a dust-collecting bag main body formed of a filter material in a bag shape, and a plate-like support bonded around the opening of the dust-collecting bag main body. In addition, an introduction port communicating with the opening of the dust collecting bag body is formed in the support for attaching the dust collecting portion of the electric vacuum cleaner.

Conventionally, since the adhesive area of the support has a required adhesive strength between the main body of the dust bag and the support,
Alternatively, when removing the dust bag from the vacuum cleaner, the shape of the dust bag body is maintained so that the dust bag can be taken out easily.Furthermore, when the dust bag is taken out, the dust bag body is caught on the dust collecting part of the vacuum cleaner. , It is usually set to be 70% or more of the area of the lower surface of the support (excluding the area of the inlet) for the purpose of preventing the dust bag body from being damaged. There is.

[0004]

However, since the adhesion area of the support body covers 70% or more of the area of the support body, the upper surface portion of the dust collecting bag body is hardly deformable. Therefore, the dust bag main body cannot be sufficiently inflated to secure a large storage volume.

The dust collecting portion of the electric vacuum cleaner has a different shape or volume depending on the type or type of the electric vacuum cleaner. On the other hand, in the dust-collecting bag housed in this dust-collecting portion, the deformation of the dust-collecting bag main body is limited due to the large bonding area of the support as described above. Therefore, depending on the shape or volume of the dust collecting part, the dust collecting bag may not be stored in the dust collecting part, and the compatibility of the dust collecting bag is not so wide.

The present invention has been made in order to solve the above problems, and is for an electric vacuum cleaner in which the storage capacity is increased and the compatibility is expanded so that it can be attached to the dust collecting portion of various vacuum cleaners. The purpose is to provide a dust bag.

[0007]

In a dust collecting bag for an electric vacuum cleaner according to the present invention, a support having an inlet for introducing dust is provided in an opening of a dust collecting bag body formed by forming a filter material into a bag shape. A dust collecting bag provided, wherein the support is bonded to the dust collecting bag main body so that the bonding area is 6% or more and less than 50% of the area of the lower surface of the support. Is characterized by.

It is preferable that a guide for forming an inlet, which can be bent and / or separated, is formed on at least a part of the periphery of the inlet of the support.

[0009]

According to the present invention, since the support is adhered to the main body of the dust bag so that the adhesive area is 6% or more and less than 50% of the area of the lower surface, the dust bag The upper surface of the main body is almost unrestrained by the support and has a high degree of freedom of deformation. Therefore, it is possible to secure a larger storage volume by sufficiently inflating the dust bag body. Also,
Since the dust collecting bag body can be arbitrarily deformed to be housed in the dust collecting portions of various electric vacuum cleaners, the compatibility is wide.

Next, the dust bag for an electric vacuum cleaner of the present invention (hereinafter referred to as the dust bag) will be described in detail with reference to the drawings. 1 is a partially cutaway perspective view showing an embodiment of the dust collecting bag of the present invention, FIG. 2 is a partially cutaway perspective view showing the dust collecting bag of FIG. 1 in the most inflated state, and FIG. 3 is shown in FIG. FIG. 3 is a plan view of the dust collecting bag of FIG.
