JPH0584190A - Dust collection bag for vacuum cleaner - Google Patents

Abstract

PURPOSE:To provide a dust collection bag which is prevented from being broken for use in a vacuum cleaner. CONSTITUTION:The outer periphery of a paper bag 8 comprising an internal paper 6 and an external paper 7 is covered with an outer bag 13 comprising nonwoven fabric so that the bag 8 is not broken by a rib, with the result that a dust collection bag having high reliability can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust bag for an electric vacuum cleaner.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand to strengthen dust collecting bags of vacuum cleaners.

A dust bag of a conventional vacuum cleaner will be described below. 3 and 4 show a conventional dust bag. As shown in the figure, the main body 1 of the electric vacuum cleaner is partitioned by a wall 5 into a mounting chamber 3 for the electric blower 2 and a dust collecting chamber 4.
The dust collection chamber 4 accommodates a paper bag 8 including a breathable inner paper 6 and an outer paper 7. The mouthpiece 1 of the paper bag 8 has a suction port 1
0 is set. The wall 5 has an air flow port 11 to the electric blower 2 and the air flow port 11 of the paper bag 8 that prevents the air flow port 11 from sticking to each other.
A plurality of ribs 12 having the same thickness are arranged.

Regarding the dust bag constructed as described above,
The operation will be described. When the electric blower 2 is operated, dust-containing air is sucked into the electric blower 2 from the suction port 10 through the paper bag 8 and the air circulation port 11. At this time, the paper bag 8 is prevented from coming into close contact with the air circulation port 11 by the rib 12.

[0005]

However, in the above-mentioned conventional configuration, the paper bag 8 is provided with the rib 1 by the suction force of the electric blower 2.
It had a problem that it was strongly pressed against 2 and broke.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a dust bag for an electric vacuum cleaner which is not easily broken.

[0007]

To achieve this object, the dust bag of the present invention has a structure in which an outer bag made of a breathable non-woven fabric is arranged on the outer periphery of a paper bag.

[0008]

Since the outer bag made of non-woven fabric is arranged around the outer periphery of the paper bag as in this structure, even if the paper bag is strongly pressed against the rib by suction of the electric blower, it is protected by the outer bag. Becomes

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 1, the dust bag has a structure in which the outer periphery of a paper bag 8 is covered with an outer bag 13 made of a breathable nonwoven fabric.

Regarding the dust bag constructed as described above,
The operation will be described with reference to FIG. When the electric blower 2 is operated, dust-containing air is sucked into the electric motor 2 through the suction port 10, the paper bag 8 and the outer bag 13, and the air circulation port 11. At this time, the outer bag 13 is moved by the rib 12 to the air circulation port 11
It is prevented from sticking to.

As described above, according to this embodiment, since the paper bag 8 is covered with the outer bag 13, it is possible to prevent the paper bag 8 from being torn even if it is strongly pressed against the rib 12 by the suction of the electric blower 2.

[0013]

As described above, according to the present invention, since the outer periphery of the paper bag is covered with the outer bag made of non-woven fabric, even if the paper bag is strongly pressed against the ribs, the outer bag protects and breaks. It is possible to realize a highly reliable dust collecting bag for an electric vacuum cleaner.
