Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a replaceable dust collection bag for a vacuum cleaner that can be installed in the collection chamber of an electric vacuum cleaner in a dislocated position. It is.

[Conventional technology]

Conventionally, the dust collection bag of this type of vacuum cleaner has a main body (2l) formed in a square tube shape, with the opening 11 (22) at the rear end folded back double or triple, as shown in Fig. 4. At the same time, the both side portions (23) (23) are configured to be foldable inward so that the opposing side portions (24) (24) can be folded in the direction in which they overlap. The opening [
A rectangular plate-shaped mouth frame (25) that follows the l-shape is fixed, a suction port (26) corresponding to the suction port of a vacuum cleaner is bored in the center of this day frame (25), and the mouth frame The front part (24a) of one opposing side surface part (24) connected to (25) is the same day frame (
25) and the rear part (2
4b) Fold blue in the direction of upward polymerization (arrow (A) direction)
It is known that it was called I-noh.

FIG. 5 shows the conventional dust collection bag (B) attached to a vacuum cleaner. In this figure, (27) is the main case, and inside this main case (27) there is a dust suction port (29) on the upper slanted front wall (28) of the case (27). ) is formed into a dust collection chamber (30) having an approximately trapezoidal longitudinal section. The dust collection bag (B) has an opposing side surface (24) (2) in the dust collection chamber (30).
4) is stored in a folded state so that it is in the vertical direction, and the mouth frame (25) is fixed and attached to the suction port (29).

[Problem to be solved by the invention]

However, with such a conventional dust collection bag, when it is attached to the dust collection chamber (30) of a vacuum cleaner, the sealed end (2
2) is linear and cannot be expanded, so the rear end portions of the opposing side surfaces (24) (24) are difficult to expand during suction of dust.

In addition, as in the vacuum cleaner shown in Fig. 5, in recent years, with improvements in usability, a hose connection pipe (32) communicating with the dust collection chamber (30) has been installed on the sloping front of the dust collection chamber (30). It is common to have a dust lid (360 degrees rotatable) attached to the 3rd eye, but in such a vacuum cleaner, the 11th frame (25) of the dust collection bag (B) is tilted. Since it will be attached to the front part (
The folded bent portion 24a) becomes an obstacle to ventilation, making it difficult to open the folded side portions (23) (23). As described above, the conventional dust collection bag (B) has a problem in that the original dust collection capacity of the dust collection bag cannot be fully utilized.

The present invention was made in order to solve such problems, and an object of the present invention is to provide a dust collection bag for a vacuum cleaner that can be easily expanded in a dust collection chamber and can be used to its full dust collection capacity. It is something.

[Means to solve the problem]

In order to achieve such an object, the present invention has a dust suction port that is formed in the main case of a vacuum cleaner and has a dust suction port in the front wall that slopes upward toward the rear of the main case.
This is a dust collection bag that is detachably installed in a dust collection chamber with a longitudinal section that is approximately trapezoidal. The bag main body, which is arranged in series and whose opening is sealed, is folded in the direction in which the opposing side parts and the bottom part merge to form a flower (1), and the bags are assembled on either one of the opposing side parts described in (1) above. This device is characterized in that a mouth frame is attached which is arranged substantially parallel to the inclined front surface of the dust chamber and communicates with the suction L1.

[For production]

According to the above configuration, when the opening frame attached to either one of the opposing side surfaces is placed approximately parallel to the inclined front surface of the dust collection chamber and installed, the four side surfaces that have been folded at the rear of the frontage will inevitably expand. When dust is sucked in in this state, the almost square-shaped bottom part rises up and faces the frame, and the main body of the bag expands into a roughly square cylinder shape, effectively saving the internal volume of the dust collection bag. It is something that can be put to good use.
