And a mount that is attached to one side on which the suction port of the strip is formed, and in a state where the bag is inflated, it faces four sides adjacent to the one side on which the strip is mounted and one side on which the mount is mounted. It is characterized in that the bag-shaped body is pressed from the side surface to be compressed and at least one end of the mount is exposed from the bag-shaped body.

[0007]

According to the first means of the present invention, since the bag-shaped body is compressed in the expanded state, it becomes easier to spread.
Further, in the compressed state, it becomes compact and the storage space does not become large.

According to the second means of the present invention, since the bag-shaped body is compressed in the expanded state, it becomes easier to spread. Further, in the compressed state, it becomes compact and the storage space does not become large. Furthermore, since the end of the mount is exposed from the bag-shaped body, the bag-shaped body does not get caught between the mount and the mounting part that locks the mount when the vacuum cleaner is mounted on the vacuum cleaner. The shape does not become difficult to spread, and the workability of mounting on the electric vacuum cleaner is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

Reference numeral 1 denotes a cleaner body, which has a dust collection chamber 2 having an upper surface opening in the front part, and a blower housing chamber 4 communicating with the dust collection chamber 2 in the rear part and having an exhaust port 3 formed in the back surface. It is provided with a case 5 and a lid 6 for closing the upper opening of the dust collecting chamber 2 so as to be openable and closable. Reference numeral 7 is 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 body 1, which communicates with the dust collection chamber 2 and has a flexible hose 9 detachably connected thereto. Reference numeral 10 denotes a rib which is formed on the bottom surface of the dust collecting chamber 2 and serves as a locking portion, 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 the upper part of the mount 20 of the dust collecting filter 13,
The mount 20 is kept in contact with the packing 12 arranged around the suction port 8 by the rib 10 and the hook 11.

Next, the dust collecting filter 13 will be described in detail. Reference numeral 14 denotes a bag-shaped body made of a filter material 15 such as a filter paper and a non-woven fabric having air permeability and flexibility, and as shown in FIG. The center portions of both lateral sides of the shape are valley-folded to form a bellows-like portion 16, and as shown in FIG. 4, both open ends 17 are rolled in and bonded by an adhesive to form a rolled-in portion 18. Formed in a bag shape. Reference numeral 19 denotes a suction port formed on the side surface of the bag-shaped body 14, which is formed on the side surface opposite to the winding direction of the winding portion 19 at both open ends 17 of the bag-shaped body 14.

Reference numeral 20 is a mount formed of a relatively hard paper such as thick paper, and a suction port 21 is bored at a substantially central portion thereof.
With the bag 21 facing the suction port 19 of the bag-shaped body 14,
A backing sheet 21 is adhered to the side surface where the suction port 19 is formed at a position where it does not overlap the winding portion 19 of the bag-shaped body 14 with an adhesive.

The bag-shaped body 14 and the mount 20 constitute a dust collecting filter 13. The bag-shaped body 14 is. As shown in FIG. 3, air is blown from the suction port 21 to inflate it into a rectangular parallelepiped shape.
Then, as shown in FIG. 1, the side surface A to which the mount 20 is adhered
The four side faces B and C adjacent to the side face are compressed by the jigs 22 and 23 toward the center of the mount 20, and the side face D of the bag-shaped body 14 facing the side A to which the mount 20 is adhered is fixed by the jig 24. After being compressed in the direction of the mount 20, the dust collecting filter 13 is formed into a flat plate shape as shown in FIG. In this state, the dust collection filter 13 is mounted
The opposite ends of 20 project from the bag-shaped body 14.

In the dust collecting filter 13, the lid 6 of the cleaner body 1 is opened, and the end of the mount 20 protruding from the bag-like body 14 is provided with the rib 10 of the dust collecting chamber 2 of the cleaner body 1. Locked to the mount 20
The upper end of the mount 20 is engaged with the hook 11 so that the side surface of the mount 20 is brought into close contact with the packing 12 of the suction port 8 of the cleaner body 1. Since the mount 20 has the opposite ends projecting from the bag-shaped body 14, it is not necessary to consider the directionality when the mount 20 is engaged with the ribs 10, and the bag-shaped body 14 is different from the mount 20. The bag-shaped body 14 is not easily opened by being sandwiched between the rib 10 and between the mount 20 and the hook 11.

In this state, the flexible hose 9, the extension pipe (not shown) and the floor suction tool are connected to the suction port 8 of the cleaner main body 1 and the electric blower 7 is operated.
Dust is sucked into the inside of 13 together with air through the flexible hose 9 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 bag-shaped body 14 is compressed in an inflated state, it is easy to spread and a large dust collecting capacity can be secured.

[0018]

As described above, according to the constitution of claim 1 of the present invention, there is an effect that the bag-like body can be more surely expanded without increasing the storage space.

According to the second aspect of the present invention, the bag-shaped body can be more surely spread without increasing the storage space, and the dust collecting filter can be mounted on the electric vacuum cleaner. It is possible to improve the effect.
