Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a vacuum cleaner in which a dust collection bag is attached in the storage section of the vacuum cleaner body, and the dust collection bag collects dust in the suction air flow. It is.

(Prior art) Recently, various vacuum cleaners have been commercialized that use disposable paper bag filters as dust collection bags that are disposed of together with the collected dust, but there is a risk of forgetting to attach a dust collection bag when using the vacuum cleaners. However, there is probably a lot of reeds, and measures are required in case you forget.

Conventionally, one example of such a countermeasure is to install a whistle that sounds when the vehicle is driven without a dust collection bag attached, and the sound of the core alerts the user that the dust collection bag (-d) has been forgotten. ,
With these types of vacuum cleaners, you only realize that you forgot to attach the dust bag when you start operating the vacuum cleaner, and by that time, air containing dust is already being sucked into the vacuum cleaner itself, and dust is being transferred to the electric feeder S and winding the machine. It is in a state of causing problems such as adhesion to the line part,
There is also a concern that the sound of the engine will be drowned out by the noise during operation, and the operator will continue to operate without noticing it, which is not very desirable in practice.

(Purpose) The present invention has been made in view of the above-mentioned problems, and eliminates the conventional drawbacks by making it possible to close the lid for opening and closing the entrance/exit of the storage section only after a dust collection bag is attached to the storage section. This solution provides something extremely advantageous in practice.

(Example) Examples of the present invention shown in the drawings will be described in detail below.

Reference numeral 6 denotes a seal gasket disposed around the entire circumference of the entrance/exit 3 of the storage section 2; 7 is a lid body for opening/closing the entrance/exit 3 of the storage section 2; the rear end side can be opened and closed with a hinge; A rib 8 whose tip abuts against the seal packing 6 is integrally formed on its inner surface.

Reference numeral 9 denotes a suction port located between the front ends of the vacuum cleaner body 1 to which a conventionally known suction horn is connected, and a suction port cover 10 is provided at the opening on the storage section 2 side. The mouthpiece cover 10 has mounting ribs 11 with appropriate elasticity on both sides of the midsection and bearings 12 on both sides of the lower part, which are integrally molded from synthetic resin, and both the mounting lips 11 and the shaft holder 12 protrude rearward. in a state. The mounting lip 11 has a locking hole 13 and has a lower end edge formed into an inclined edge 14 that gradually becomes lower toward the bottom, and is located slightly on the inner side of the bearing 12 .

Reference numeral 15 denotes a split mounting plate made of a synthetic resin molded product, with a shaft 16 integrally molded on both sides of the lower end and a protrusion 17 on both sides of the midsection, and the shaft 16 is attached to the bearing 12 from above. After fitting, push the protrusion 17 between both mounting lips 11 into the locking hole 1.
3 to attach it to the mouthpiece cover 10. 18 is a receiving part integrally formed on both sides of the lower part of the split mounting plate 15, and 19 is a locking piece integrally molded on the upper part of the split mounting plate 15, which is approximately U-shaped horizontally and has appropriate elasticity and is free. It has a structure with a claw 20 on the edge, and the bent part 19a is on the opposite side to the surface where the receiving part 18 is located [6, the free end side having the claw 20 is connected to the same side as the receiving part 18 through the open part 21. Located protruding from the side. Reference numeral 22 denotes a communication hole formed in the center of the split mounting plate 15, into which a mouthpiece gasket 23 is fitted to bring the gasket 23 into close contact with the mouthpiece cover 10 and the mounting plate described below. 24 is a paper dust collection bag equipped with a mounting plate 25 made of cardboard or the like at the opening;
5 has a dust suction port in the center. Reference numeral 27 denotes a protrusion integrally provided on the inner surface of the lid 7, which abuts against the upper edge of the split mounting plate 15 and the stop piece 19 when the lid 7 is closed.

Reference numeral 28 denotes a lid blocking body provided on the upper part of the mouthpiece cover 10 so as to be able to swing around a fulcrum part 29, with a blocking part 30 at one end,
Each has a sensing portion 31 at the other end, and is always urged in one direction by a spring 32.

Thus, the lid blocking body 28 positions the blocking part 30 above the seal packing 6 by the biasing force of the spring 32, and when it is swung against the spring 32, it moves the blocking part 30 away from above the seal packing 6. let Moreover, the sensing part 31 of the lid blocking body 28 is in a state of protruding toward the storage part 2 side, and comes into contact with the mounting plate 25 when the dust collection bag 24 is attached to the suction cover 10 with the split mounting plate 15, and the lid is closed. The blocking body 28 is swung against the spring 32.

In the above configuration, the dust collection bag 24 is attached to the mounting plate 25 with the lower edge of the mounting plate 25 fitted into the receiving part 18 of the split mounting plate 15.
It is attached by engaging the upper edge of the locking piece 19 with the claw 2o of the locking piece 19, and in this attached state, the dust suction port of the mounting plate 25 and the communication port 22 of the split mounting plate 15 match and are in communication.

To remove the dust collection bag 24, compress the bent portion 19a side of the locking piece 19 to bend the locking piece 19 upward, and then remove the claw 20 and the mounting plate 2.
This is done by releasing the binding with 5.

Next, the split mounting plate 15 attaches the shaft portions 16 on both sides of the lower end to the bearing 1.
2, rotate it in the direction shown by the arrow in FIG.
It is attached to the suction port cover 10 by engaging with the suction port 9, and the communication port 22 is communicated with the suction port 9 portion. In this state, if the dust collection bag 24 is attached to the split mounting plate 15. The sensing portion 31 of the lid blocking body 28 inserted through the open portion 21 of the split mounting plate 15 comes into contact with the mounting plate 25 as shown in FIGS. 5 to 7, and the lid blocking body 28 swings against the spring 32. The blocking portion 30 is moved away from above the seal packing 6. Therefore, the lid 7 can close the entrance/exit 3 of the storage section 2 by bringing the rib 8 into contact with the seal packing 6, and the projection 27 can come into contact with the upper edge of the split mounting plate 15 and the locking piece 19.

On the other hand, if the dust collection bag 24 is not attached to the split mounting plate 15, the lid blocking body 28 will not swing against the nulling ring 32, and the blocking part 30 will be sealed as shown in FIGS. 8 and 9. Located on Patsukin 6. Therefore, even if the lid body 7 is closed, the lip 8 hits the blocking part 30 and cannot come into contact with the seal packing 6, and the closure is not prevented.
By using this, you will know about forgetting. In this way, since it is possible to know whether the dust collection bag 24 has been left on when closing the intangible body 7, there is no need to operate the vehicle with the dust collection bag 24 left on, that is, perform cleaning work.

The split mounting plate 15 is removed by forcibly rotating it in a direction away from the mouthpiece cover 10 to release the engagement between the protrusion 17 and the locking hole 13, and then pulling it upward.

When pulling up the split mounting plate 15, the shaft portion 16 is
As shown in the figure, since it hits the inclined edge 14 and is guided in the direction away from the mouthpiece cover 10, it is pulled up smoothly without being caught by the sensing part 31 of the lid blocking body 29 that is in the upwardly protruding state.

In the present invention, the lid blocking body 28 is not limited to one that is operated directly by the dust collection bag 24, but may be operated indirectly. Any device that can be moved away from the blockage position 7 will suffice. Further, the present invention can be practiced even if there is a vacuum cleaner K in which the dust collector 24 is directly attached to the storage section 2 (one without the split mounting plate 15). In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and it goes without saying that the present invention can be implemented with appropriate modifications within the scope of the gist.

(Effects) As described above, according to the configuration of the present invention, it is possible to know when the dust collection bag has been attached depending on the condition of the lid that opens and closes the entrance/exit of the storage section, and the dust collection is performed only after the operation has started. The attachment of the bag eliminates the drawbacks of the conventional ones where it is easy to forget the item, and is extremely advantageous in practical terms.
