Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a vacuum cleaner, and in particular, to a vacuum cleaner that uses a disposable paper bag or other filtration filter, and in which a paper bag or the like is attached to a dust case of the vacuum cleaner. It made it possible to escape. It has a lid body with a suction port, which can be used to protect paper bags etc. when used for locking, and can be remanufactured with a dust removal device, so that it can be used separately. It concerns vacuum cleaners.

[Background of the invention]

Conventionally, in this type of vacuum cleaner, as shown in Japanese Utility Model Application Publication No. 52-50564, there was a dual-purpose type in which a paper bag filter was combined with a cloth filter, but the filtration method and garbage disposal method of each were different. It was not popular because it had many disadvantages such as losing its advantages, being difficult to use, and severely deteriorating its performance.

In other words, the sanitary waste disposal and ease of handling that disposable filters have, but the installation of a paper bag with the same opening as the cloth filter is greatly hindered by the structure, and in the case of reusable cloth filters,
It is very difficult to remove dust from the cloth filter formed in a paper bag, and its recovery performance is poor.Also, when disposing of garbage, you are forced to pull out the cloth filter and dispose of it in an unsanitary manner. Even when using , the results were half-hearted.

In addition, at least as a configuration related to the dust case, there is a structure in which a filter is placed inside the dust case having an intake port on the axial side surface, and a garbage bag is fastened to the inner surface of the lid. This necessitates the unsanitary handling of storing garbage and taking it outside, and the two openings involved are taking out the garbage bag and removing the guest case from the main case and taking out the filter. It was also difficult to handle, as it was impossible to dispose of the waste unless it was done.

[Purpose of the invention]

The present invention solves the above-mentioned drawbacks, and relates to a dual-purpose filter that can fully utilize the characteristics of a disposable filter and a reusable filter, and at the same time is hygienic. The purpose is to provide a vacuum cleaner that is easy to handle.

[Summary of the invention]

The vacuum cleaner according to the present invention has a structure in which a dust case containing a filtration filter is removably attached to a vacuum cleaner body case containing an electric blower, a cord winding device, etc. The lid is attached to the case so that it can be opened and closed, and has a suction port, so that the disposable bag-like filter can be attached to and removed from the dust case. A filter unit 1-, which is also used for maintenance and carrying, is detachably attached to the dust case.

More specifically, a lid body having a suction port is attached to the dust case so as to be openable and closable, and a bag-shaped filter such as a disposable paper bag can be removably attached to the inside of the lid body so as to communicate with the suction port. On the other hand, a coarse filter, a fine filter, and the corresponding This vacuum cleaner is equipped with a reusable filter unit that is removably installed in combination with a fine filter dust removal device.

1o is a dust case that is detachably attached to the main body case 1, and is made of a material such as synthetic resin or copper plate,
A first opening A is opened on the side of the engagement surface with the main body case 1, and a second opening B is provided in a different part of the guest case 10 from the first opening A.

A protrusion 11 that fits into the receiving part 4 of the main body case 1 and a case clamp 13 via a spring body 12 are arranged on the first opening A side, and the dust case 10 is , this protrusion 11 and the case screw 13
1 is removably attached to the main body case 1.

On the other hand, a lid body 18 is provided on the second opening B side of the dust case 10.
The rotation shaft portion 14 and the lid hook portion 15 are not provided.

Further, the dust case 10 is also provided with an auxiliary handle 16, casters 17 for traveling, and the like.

Thus, this is the gist of the invention. The structure of the parts related to the lid body, filter unit, etc. is as follows.

That is, in the second opening B of the dust case 10,
A lid body 18 that closes the opening is the dust case 10.
It is pivotally supported by a rotating shaft portion 14 and is attached so as to be openable and closable.

This lid body 18 is provided with a lid clamp 19 via a spring body 20, which hooks and holds the hook part 15 of the guest case 10, and furthermore, the lid cover 21 is attached to a screw 22.
A cover gasket 23 for keeping the second opening'B surface airtight is attached.

The lid body 18 is also provided with a suction port 24 to which a hose, an extension pipe, a suction port, etc. (not shown) are connected, and for sucking in dirt.
is installed.

Further, the lid cover 21 is provided with a paper bag attachment/removal [26] for removing the paper bag 27 related to the bag-shaped filter and the cellar 1-L so as to communicate with the suction port 24.

The paper bag 27 is made of filter paper or the like, and at its entrance, the paper bag 27 is connected to the suction port 24 by a paper bag engagement/disengagement device 26 provided on the lid cover 21 of the lid 18, and a paper bag packing 25 is connected to the paper bag 27. A locking piece 28 is fixed by adhesive, welding, or the like to ensure airtight retention.

Therefore, the paper bag 27 can be easily engaged and disengaged by holding the locking piece 28 with the paper bag engagement and disengagement device 26 and releasing it.

Next, 29 is a filter unit detachably attached to the first opening A side of the dust case 10.

This filter unit 29 includes a fine filter 30, a coarse filter 31, a dust removal device 32 for removing dust stuck to the fine filter 30, and a first opening A of the dust case 10 by combining these parts. It is composed of a filter packing 33 that can be attached to and detached from the housing and has the role of keeping it airtight.

The fine filter 30 has a filtration part 34 made of cloth, nonwoven fabric, etc., and a frame part made of synthetic resin or the like, which is integrally connected to the filtration part 34 and has shape-retaining properties. It consists of 35.

Further, the coarse filter 31 is composed of a coarse filtration section 36 made of a wire mesh 9 or a synthetic resin net, and a frame section 37 for retaining the shape of the coarse dust filtration section 36 .

Furthermore, the dust removal device 32 is a device that removes the dust that has clogged the filtration part 34 of the fine filter 30 by giving it vibration by hitting or rotating it. Methods can be selectively adopted as needed.

Therefore, 38 is a part or the entire circumference of the inner circumferential surface of the dust case 10 (in the example shown in FIG. 7, it is the entire circumference).
This is an auxiliary coarse filter installed over the whole area, and is composed of a coarse dust filter section 39 and a shape retaining frame section 40.

The auxiliary coarse filter 38 is disposed so as to have a small distance from the dust and the inner circumferential surface of the case 10, has sufficient resistance to wind pressure caused by air flow, and has an air passage between it and the inner circumferential wall of the dust case 10. It is arranged as follows.

In the above embodiment, an example in which the auxiliary coarse filter 38 can be separated from the coarse filter 31 and an example in which the auxiliary coarse filter 38 is arranged all around the inner peripheral surface of the dust case 10 has been described. For example, the coarse filter 31 alone may be used instead.

In short, the auxiliary coarse filter 38 can be configured integrally or separately from the coarse filter 31, or can be configured without the coarse filter 31.
By providing a separate peripheral edge structure, or by providing ribs on the opposing wall surface to be in contact with, or by making the wall surface have an uneven structure, the air passage as described above is formed, and the paper bag 27 is brought into close contact with the wall surface as described below. It is preventable.

Note that 41 in the figure indicates dust.

Next, the operation of the vacuum cleaner configured as described above will be explained.

The vacuum cleaner according to the present invention is basically used with a paper bag 27 attached, as shown in FIG.

First, as shown by the arrow in the figure, when an airflow containing dust and the like flows through the suction port 24, the airflow flows into a paper bag 27 that is set in communication with the suction port 24.

At this time, the paper bag 27 inflates like a balloon due to the pressure of the air flow and the M force caused by the collision of the collected dust, but if it is allowed to inflate freely without regulation, the paper bag 27 will burst. However, in the structure described above, the coarse filter 3 no longer functions as a filtration filter.
1 and the auxiliary coarse filter 38 serve to restrict the expansion of the paper bag 27 and prevent it from bursting.

And this is caused by the expansion of the paper bag 27.
It completely adheres to the wall surface of an impermeable object such as the dust case 10, and prevents the air permeability of the paper bag 27 from being obstructed at the close contact portion. like.

The same effect can be expected by using a separate peripheral edge of the coarse filter 31 or by providing a wall with ribs or irregularities.

Therefore, the paper bag 27 is strongly protected by the coarse filter 31 and the auxiliary coarse filter 38,
The air permeability is not hindered, and the sucked-in dust can be filtered, and all of it, like the dust 41 shown in FIG. 1, is collected in the paper bag 27.

The clean air that has passed through the paper bag 27 is filtered through a coarse filter 31 as shown by the arrow in Figure 1. After passing through a fine filter 30,
It passes through the electric blower v&6 and is discharged to the outside from the main body case 1.

That is, when used in the manner shown in FIG. 1, the coarse filter 31 of the present invention serves to protect the strength of the paper bag 27 and maintain the ventilation path,
0 and 0 do not work as a filtration filter.

In short, these filters are used to protect and maintain the safety of the paper bag 27 during use.

When the paper bag 27 is full, the garbage 41 collected in this manner is removed by opening the lid 18 by operating the lid clamp 19 and operating the paper bag locking/disengaging device 26, as shown in FIG. Then, the user can remove the paper bag 27 and throw it away together with the paper bag 27 in a trash can, etc., and the user does not have to see the accumulated garbage when disposing of the garbage, nor is the user covered with debris when disposing of the garbage. Garbage disposal is done in a very sanitary manner.

Further, the paper bag 27 filled with garbage 41 is thrown away,
If you set a new spare paper bag 27, the vacuum cleaner will once again exhibit the same suction performance as new, and is superior in terms of performance maintenance compared to conventional vacuum cleaners that use reusable filters. The trouble of cleaning the filter can also be omitted.

However, since the paper bag 27 is disposable, if the paper bag 27 becomes full during cleaning and you do not have a spare, or if you forget to buy a spare, you will not be able to use the vacuum cleaner. That's inconvenient.

However, in contrast to this, according to the present invention, as shown in FIG. Next, fine dust (sand, clumps, etc.) is supplemented with a fine filter 30, and the dust 41 is directly accumulated in the dust case 10. When disposing of the garbage, as shown in FIG. The filter unit 29 can be removed by operating the case clamp 13, the filter unit 29 can be taken out, and the dust 41 accumulated in the dust case 10 can be thrown away.

As described above, according to the present invention, as a result,
By arbitrarily selecting and opening either the first opening A or the second opening B provided in the dust case 10,
Each one was different. Garbage can be disposed of using a filtration filter.

In each case, it is only necessary to remove either the case clamp or the lid clamp, and compared to the conventional method in which both clamps are removed, the handling is easier. It is far superior.

In this way, the paper bag 27 is easily damaged by inconvenient dust, such as metal pieces, nails, and rivets, no matter how protective it is. In the case of defective garbage, such as garbage with a lot of fine dust that is difficult to dispose of and that tends to form lumps, the dust should be collected using a paper bag 27 and disposed of in a sanitary manner. This provides a multifunctional vacuum cleaner that can be used selectively.

In short, the filter described in the above embodiment is attached to the dust case so that it can be opened and closed, and the lid body is formed with a suction port, so that the disposable bag-shaped filter can be inserted into and removed from the dust case. The present invention relates to a vacuum cleaner in which a filter unit 1 to 1, which is configured to protect and support a bag-like filter when used in a locked state, is detachably attached to the dust case. When using a bag-like filter such as a paper bag,
The bag-shaped filter can collect all the dust that has been sucked in, and the accumulated garbage will accumulate inside the bag, so all you have to do is open the lid, take out the bag-shaped filter, and throw it away together with the bag. , there is no need to worry about cleaning filters, and by simply attaching and replacing a spare bag-shaped filter, you can start cleaning with suction performance as good as new, which improves hygiene and performance of garbage disposal. The durability of the bag-shaped filter can be measured, and its handling is very simple.In this case, the filter unit is a reasonable one used to protect and maintain the safety of the bag-shaped filter. It has become.

In addition, if you do not have a spare bag-shaped filter, or if you have used a filter unit that can be turned over for some reason, such as the type of object or garbage being cleaned, there are currently Similar to known vacuum cleaners, remove the dust case part from the main case side, operate the dust removal device, etc. to remove dust from part of the clogged fine filter, and then pull out the filter unit from the dust case. The garbage accumulated in the dust case can be disposed of in a trash can or the like, and garbage disposal can be performed in exactly the same manner as a conventional vacuum cleaner.

In any of the above cases, opening the lid or removing the dust case from the main case side
It is sufficient to perform either one of these operations, and the overall operability is good.

As a result, it is possible to obtain a disposable bag-like filter that is easy to handle and ensures sanitary garbage disposal, and also helps to protect the strength and maintain the shape of the bag-like filter. It can be combined with a filter unit (using...

In addition, in the above embodiment, a paper bag made of paper such as filter paper was explained for a disposable bag-like filter, but the material is not limited to paper, and any economically superior material can be used. This does not preclude the use of any material that does not impair its functionality.

〔Effect of the invention〕

The present invention relates to a dual-use type that can fully utilize the characteristics of a disposable filter and a reusable filter, and at the same time has a multifunctional cleaning mode that is hygienic and easy to handle. It is possible to obtain a vacuum cleaner that enables this, and it can be said that this invention is highly practical.
