Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a vacuum cleaner in which a dust collection bag is installed in a storage part using a bag attachment plate, and particularly to a dust collection bag attachment device.

<Conventional technology> The conventional vacuum cleaner dust collection bag attachment device was developed in 1982.
As stated in Publication No. 99657, a plate-shaped knob is provided at the upper end of the bag support plate for attaching the dust collection bag to the dust collection chamber, a first support rib is provided near the upper end of the bag support plate, and a first support rib is provided near the lower end of the bag support plate. A second support rib having a protrusion was provided on the top. Then, the first bag support plate
The support rib supports the upper end of the mouth plate of the dust collection bag,
The protrusion of the second support rib is pushed outward to support the lower end of the opening plate on the second support rib, and
The mouth plate is held between a support rib and a second support rib,
The dust collection bag was installed in the dust collection chamber by holding the knob of the bag support plate by hand.

<Problem to be solved by the invention> If the dust collection bag attachment device for a vacuum cleaner as described above is used, when discarding the dust collection bag, the bag support plate can be held by holding the plate-shaped knob part of the bag support plate with one hand. Remove the bag from the dust collection chamber, turn the bag support plate upside down, and use your other hand to push the protrusion of the second support rib outward to remove the dust collection bag from the bag support plate. There were problems in that unnecessary force was required to do this, it was necessary to change hands to turn the bag support plate upside down, and it was time-consuming and troublesome to dispose of the dust collection bag, resulting in poor workability.

The object of the present invention is to provide a dust collection bag attachment device for a vacuum cleaner that eliminates the above-mentioned problems.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the vacuum cleaner dust collection bag attachment device of the present invention has a dust collection bag having a mounting plate at its mouth and a detachable mounting plate. A bag mounting plate is provided, and a receiving portion into which the lower end of the mounting plate fits into the bag mounting plate, and a locking piece having appropriate elasticity and engaging and releasing a claw from the upper end of the mounting plate are integrally molded. , the locking piece is formed in a generally U-shape lying upside down, and its upper end is provided at the upper end of the bag mounting plate, and its other free lower end is inserted through an opening provided at the top of the bag mounting plate. and protrudes on the same side as the receiving portion, and the claw is provided on the lower surface of the free lower end.

<Function> The dust collection bag attachment device for a vacuum cleaner configured as described above fits the lower end of the dust collection bag attachment plate into the receiving part of the bag attachment plate and compresses the bent part of the locking piece of the bag attachment plate. The dust collection bag is attached to the bag attachment part by bending and engaging the upper end of the mounting plate with the claw at the free lower end of the locking piece, and the dust collection bag is installed in the dust collection chamber.

When discarding the dust collection bag, put your finger inside the bent part of the locking piece, remove the bag mounting plate from the dust collection chamber, compress the bent part of the locking piece, and then press the top of the mounting plate. and the claw at the free lower end of the locking piece, the lower end of the mounting plate is pulled out from the receiving portion of the bag mounting plate, and the dust collection bag is removed from the bag mounting plate and discarded.

<Example> Hereinafter, the example of the present invention shown in FIGS. 1 to 3 will be described in detail.

Reference numeral 1 denotes a vacuum cleaner main body which has an electric blower installed in the rear half and a storage section 2 in the front half with the top opening serving as an entrance/exit 3, and is equipped with running wheels 4 on both sides of the rear and swivel wheels 5 on the bottom of the front. . 6 is a suction port formed on the front end surface of the vacuum cleaner body 1, and its inner end is connected to the storage section 2.
Open in front of. Reference numeral 7 denotes a lid body for opening and closing the entrance/exit 3 of the storage section 2, and its rear end side is pivoted with a hinge so that it can be opened and closed freely. Reference numeral 8 denotes a paper dust collection bag having a mounting plate 9 made of cardboard at its mouth, and a dust suction port 10 in the center of the mounting plate 9.

11 is a bag mounting plate made of molded synthetic resin;
There is a receiving part 12 located on both sides of the lower end of one plate surface into which the lower edge of the mounting plate 9 is fitted from above, and a claw 14 at the free end which is located at the upper part and has appropriate elasticity and is attached to the upper edge of the mounting plate 9. It is integrally molded with a locking piece 13 that engages and disengages, and has a communication port 15 in the center of the plate surface, and a mouthpiece gasket 16 is fitted into the port 15.

The above-mentioned locking piece 13 has a substantially U-shape lying sideways, and its bent part 13a is located on the opposite side to the surface where the receiving part 12 is located, and the free end side having the claw 14 is connected to the receiving part through the open part 17. It is located protruding on the same side as the Therefore, the dust collection bag 8 connects the lower edge of the mounting plate 9 to the bag mounting plate 1.
It is installed by engaging the upper edge of the mounting plate 9 with the claw 14 of the locking piece 13 while the mounting plate 9 is fitted from above into the receiving part 12 of the mounting plate 9. In this mounted state, the dust suction port 10 of the mounting plate 9 and the bag It matches the communication port 15 of the mounting plate 11 and is in a communicating state. The dust collection bag 8 is removed by compressing the bent portion 13a of the locking piece 13 to bend the locking piece 13 in the direction of the arrow, and releasing the engagement between the claw 14 and the mounting plate 9.

The bag mounting plate 11 is attached to the front side of the storage section 2, and for example, its lower edge is attached to the storage section 2.
It is attached by fitting into a fitting part (not shown) provided at the lower part of the lid body 7 and pressing the upper edge part with a protrusion 7a on the inner surface of the lid body 7. When the bag mounting plate 11 is installed, the communication port 15 is located between the suction port 6 and the dust suction port 10 to communicate the two, and the locking piece 13 is located on the side of the entrance/exit 3 of the storage section 2 and is connected to the bag mounting plate. It is in a state where it can be used as a knob when putting in and taking out the item 11.

<Effects of the invention> Since the vacuum cleaner of the present invention has the above-mentioned configuration of the dust collection bag attachment device, the bent portion of the locking piece can be used as a knob when inserting and removing the bag attachment plate. Holding the locking piece, take out the bag mounting plate, compress the bent part of the locking piece, and release the engagement between the claw of the locking piece and the upper end of the dust collection bag mounting plate. There is no need to change the bag mounting plate as in the conventional case, the dust collection bag can be easily replaced, and there is no need to provide a separate knob for taking in and out the bag mounting plate.
