Abstract

PURPOSE:To simplify the folding method of a bag-like body and improve the expanding performance of the bag-like body by folding one stuck end section of the bag-like body to the back face side of a mount in the direction perpendicular to both side sections of the bag-like body, and folding the mount and the bag-like body to the back face side of the mount parallel with both side sections of the bag-like body. CONSTITUTION:A suction port 22 is bored at the nearly center section 1 of a mount 21 made of relatively hard paper, and an adhesive is stuck on the side face where the intake port of a bag-like body 14 is formed while the suction port 22 is faced to the intake port of the bag-like body 14. The fold line 23 of the mount 21 is formed in the direction perpendicular to the end section protruded from a fold section 24 in the folded state and parallel with bellows- like sections 16. One wound section 19 side of the bag-like body 14 is folded to the side face side different from the side face where the mount 21 is stuck in the direction perpendicular to the bellows-like section 16 of the bag-like body 14. The bag-like body 14 is folded so that the end section of the mount 21 is protruded from the fold section 24 and the wound sections 19 are not overlapped on the mount 21.

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 at a front portion thereof, and a blower housing chamber 4 communicating with the dust collection chamber 2 at a rear portion thereof and having an exhaust port 3 formed at a rear surface thereof. 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 a locking portion formed on the bottom surface of the dust collecting chamber 2 and holds a lower end of a mount 21 of a dust collecting filter 13 described later. Reference numeral 11 denotes a hook rotatably supported on the upper part of the dust collecting chamber 2, which holds an upper part of the mount 21 of the dust collecting filter 13 and
The mount 21 is brought into contact with the packing 12 arranged on the periphery of 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 or a non-woven fabric having air permeability and flexibility, and as shown in FIG. 3, the ends of the filter material 15 are adhered and bent into a tubular shape having a rectangular cross section and a rectangular cross section. Forming a bellows-like part 16 by valley-folding the center part of both lateral sides of the shape, and forming a winding part 19 by winding both side open ends 17 and adhering with an adhesive to form a bag-like shape. There is. Reference numeral 20 is a suction port formed on the side surface of the bag-shaped body 14.

Reference numeral 21 is a mount formed of a relatively hard paper such as cardboard, and a suction port 22 is formed at a substantially central portion thereof.
With the bag 22 facing the suction port 20 of the bag-shaped body 14,
Is adhered to the side surface on which the suction port 20 is formed by an adhesive. Reference numeral 23 denotes a folding curve formed on the mount 21, which is in a folded state to be described later, in a direction orthogonal to an end portion of the bag-like body 14 projecting from the folding portion 24, in other words, a bellows-like portion 16
It is formed in parallel with.

The bag-shaped body 14 and the mount 21 constitute a dust collecting filter 13. The bag-shaped body 14 has one winding portion 19
The side is folded in a direction orthogonal to the bellows-like portion 16 of the bag-shaped body 14 and on a side surface side different from the side surface on which the mount 21 is attached. In this folded state, the bag-shaped body 14 is arranged so that the end portion of the mount 21 projects from the folded portion 24.
The 14 winding portions 19 are folded so that the winding portions 19 do not overlap the mount 21. And the dust collection filter 13

The end of the mount 21 protruding from the folding portion 24 is locked to the rib 10 of the dust collecting chamber 2 of the cleaner body 1, the upper end of the mount 21 is engaged with the hook 11, and the side surface of the mount 21 is attached to the cleaner body 1. Adhere closely to the packing 12 of the suction port 8. Since the end of the mount 21 that engages with the rib 10 is projected from the folded portion 24 of the bag-shaped body 14, the folded portion 24 of the bag-shaped body 14 is sandwiched between the mount 21 and the rib 10 to form a bag-like shape. The body 14 does not become difficult to open, and the mounting workability is improved. Further, the mount 21 is folded at a right angle to the end protruding from the folding portion 23 of the bag-shaped body 14, and when mounted on the cleaner main body 1, the rib 10 and the hook 11 of the cleaner main body 1 are removed. Since both sides of the mount 21 are supported with respect to the folding curve 23, the flat state of the mount 21 can be reliably maintained.

The dust collecting filter 13 has a winding portion 19 of the bag-shaped body 14.
Since the winding portions 19 and the mount 21 are folded so that they do not overlap with each other, the thickness in the folded state can be reduced.
