[Industrial applications]

 The present invention relates to a disposable dust collecting filter used in a vacuum cleaner.

[0002]

[Prior art]

 Conventionally, as this kind of dust collecting filter, for example, one disclosed in Japanese Patent Publication No. 2-56090 (A47L 9/14) is known. This dust collection filter mounts a backing sheet on a bag-shaped body made of filter material, folds both sides of the bag-shaped body into a bellows shape, and wraps the open ends of both sides in a direction orthogonal to both sides, with the back surface of the backing sheet being It has a structure that is folded multiple times to the side.

However, in this configuration, since the folding method is complicated, it is difficult to open the folded portion, and the bag-shaped body is attached to the cleaner body, the shape of the dust collecting chamber of the cleaner body, and the cleaner. Due to factors such as the suction performance of the main unit, the bag-shaped body may not be completely opened, and the dust collection capacity may be significantly reduced, or the specified suction performance may not be obtained.

[Action]

 According to the first means of the present invention, since the bag-shaped body is an extremely simple folding method in which only one end side is folded, the folded portion is easy to open and the bag-shaped body is surely expanded. Also, since the bag-shaped body is folded so that the rolled-in portions and the rolled-in portion and the backing sheet do not overlap, the dust collecting filter becomes thin in the folded state, and the storage space becomes smaller.

According to the second means of the present invention, since the bag-shaped body is folded only at one end side and is an extremely simple folding method, the folded portion is easy to open and the bag-shaped body surely spreads. . Also, since the bag-shaped body is folded so that the rolled-in portions and the rolled-in portion and the backing sheet do not overlap, the dust collecting filter becomes thin in the folded state, and the storage space becomes smaller. Further, since one end of the mount is projected from the folding part of the bag-like body, when it is inserted into the dust collecting chamber of the electric vacuum cleaner from this one end side, the mount locking part formed in the dust collecting chamber and the mount are separated from each other. The bag-shaped body does not get caught between them, the spread of the bag-shaped body is not hindered, and the workability of attaching the dust collecting filter to the vacuum cleaner is improved.

【Example】

 An embodiment of the present invention will be described in detail below with reference to FIGS.

Reference numeral 1 denotes a cleaner body, which has a dust collecting chamber 2 having an upper surface opening at a front portion thereof, and a blower housing chamber 4 communicating with the dust collecting chamber 2 at a rear portion thereof and having an exhaust port 3 formed at a rear wall thereof. It is provided with a main body case 5 and a lid body 6 that opens and closes an upper opening of the dust collecting chamber 2. Reference numeral 7 denotes an electric blower housed in the fan housing chamber 4.

Reference numeral 8 denotes a suction port formed in the front portion of the cleaner main body 1, which communicates with the dust collection chamber 2 and a flexible hose 9 is detachably connected. Reference numeral 10 denotes a rib which is a locking portion formed on the bottom surface of the dust collecting chamber 2 and holds a lower end of a mount 20 of a dust collecting filter 13 described later. Reference numeral 11 denotes a hook that is rotatably supported on the upper part of the dust collecting chamber 2 and holds an upper part of the mount 20 of the dust collecting filter 13, and the mount 20 of the dust collecting filter 13 is fixed by the rib 10 and the hook 11. It is brought into contact with a packing 12 arranged on the periphery of the suction port 8.

Next, the dust collecting filter 13 will be described in detail. Reference numeral 14 is a bag-shaped body made of a filter material 15 such as a filter paper or a non-woven fabric having air permeability and flexibility. As shown in FIG. 3, the filter material 15 is attached at its end portion and bent into a tubular shape having a rectangular cross section. A center portion of both lateral sides having a rectangular cross section is valley-folded to form a bellows portion 16, and the open ends 17 on both sides are wound and adhered with an adhesive to form a bag shape. Reference numeral 18 denotes a suction port formed on a side surface of the bag-shaped body 14, which is located on a side surface of the bag-shaped body 14 opposite to the winding direction of the winding portion 19 at both open ends 17 and close to one opening end 17. Has been formed.

Reference numeral 20 denotes a backing sheet made of relatively hard paper such as thick paper. A suction port 21 is formed at a substantially central portion, and the suction port 21 is opposed to the suction port 18 of the bag-shaped body 14. In this state, the backing sheet 20 is adhered to the side surface of the bag-shaped body 14 where the suction port 18 is formed at a position not overlapping the winding portion 19 of the bag-shaped body 14 with an adhesive. The suction port 21 of the mount 20 has a larger diameter than the suction port 18 of the bag-shaped body 14.

The bag-shaped body 14 and the mount 20 constitute a dust collecting filter 13. The bag-shaped body 14 has the other winding part 19 side different from the one winding part 19 adjacent to the suction port 18 in the direction orthogonal to the bellows part 16 of the bag-shaped body 14 and of the mount 20. Folds to the side different from the attached side. In this folded state, the bag-shaped body 14 is folded such that the end of the mount 20 projects from the folded portion 22 and the winding portion 19 of the bag-shaped body 14 does not overlap.

Thus, the dust collecting filter 13 opens the lid 6 of the cleaner body 1, and the end of the mount 20 protruding from the folded portion 22 of the bag-like body 14 is collected by the cleaner body 1. It is locked to the rib 10 of the dust chamber 2, and the upper end of the mount 20 is engaged with the hook 11 so that the side face of the mount 20 is closely attached to the packing 12 of the suction port 8 of the cleaner body 1. Since the end of the mount 20 that engages with the rib 10 is projected from the folded portion 22 of the bag-shaped body 14, the folded portion 22 of the bag-shaped body 14 is sandwiched between the mount 20 and the rib 10 to form a bag-like shape. The body 14 does not become difficult to open.

In this state, when a flexible hose 9, an extension pipe (not shown) and a floor suction tool are connected to the suction port 8 of the cleaner body 1 and the electric blower 7 is operated, the dust collection filter 14 is placed inside. The dust is sucked together with the air through the flexible hose 8 and the like, and the bag-like body 14 of the dust collecting filter 13 spreads due to the pressure, and the dust is separated and left to pass only the air.

Since the dust collecting filter 13 is mounted in the dust collecting chamber 2 with the folded portion 22 of the bag-shaped body 13 facing downward, the free end side of the bag-shaped body 14 to which the mount 20 is not attached is directed downward. The other side surface of the bag-shaped body 14 to which the backing sheet 20 is not adhered is expanded by the pressure of the sucked air as shown by the broken line in FIG. From the folded state, the other side surface of the bag-shaped body 14 is expanded obliquely upward and rearward from the folded state to the vicinity of the inner surface of the lid body 6 to ensure a large dust collecting capacity.

In the above-described embodiment, the winding portion 19 of the bag-shaped body 14 is wound on the other side surface side where the mount 20 is not adhered, but as shown in FIG. 5, the side surface where the mount 20 is adhered is shown. You may get caught in the side. When the dust collecting filter 13 is mounted in the dust collecting chamber 2 by bringing the winding part 19 close to the end of the mount 20, the lower end of the mount 20 is locked to the rib 10 by pressing the winding part 19. It is possible to improve the mounting workability.

Further, when the bag-shaped body 14 is large, as shown in FIGS. 6 to 8, even if the free end side of the bag-shaped body 14 to which the mount 20 is not attached is folded into a bellows shape a plurality of times. Good. At this time, by folding the folding part 22 and the winding part 20 so that they do not overlap with each other, the thickness of the dust collecting filter 13 in the folded state can be reduced, and the storage space for the dust collecting filter 13 can be reduced. Can be made smaller.
