Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention 1 relates to a vacuum cleaner using both a disposable filter and a reusable filter.

[Conventional technology]

For this type of vacuum cleaner, for example, Japanese Patent Laid-Open No. 49-8835
As shown in Japanese Patent Application No. 7, it is known that a cylindrical disposable filter that is compressed to a small size so as to be able to be supplied for a long period of time is provided in the front lid of a dust case. This device has the advantage that it can be installed in the dust case so that the disposable filter can be used automatically without having to replace the disposable filter.
For this purpose, the filter has an extremely complicated structure requiring a suturing mechanism and a cutting/separation mechanism for the unused portion and the used portion of the disposable filter. Moreover, the filter device provided in the dust case shown in the above publication has the function of preventing the disposable filter from coming into close contact with the inner wall of the dust case and the function of regulating the swelling of the disposable filter. However, it does not have a structure that can independently trap fine dust that has flowed into the dust case without using a disposable filter.

Furthermore, the disposable filter shown in the above publication opens the front lid of the dust case and attaches it to the front lid.
When in use, the tip of the disposable filter is sutured to spread it inside the dust case, and after use, the rear end of the used part of the disposable filter is sutured, and the unused part and the used part of the disposable filter are cut. The main body case and dust case are always separated, and the used disposable filter is taken out from the main body case joint surface of the dust case.

[Problem that the invention seeks to solve]

In the above conventional example, if you get sick, forget to attach the disposable filter, or operate the electric motor without knowing that the disposable filter is used up,
Most of the fine dust that enters from the suction port of the dust case passes through the filter device and reaches the electric motor.
It cannot function as a vacuum cleaner.

Furthermore, in the conventional example described above, in order to make the disposable filter usable, it is necessary to sew the disposable filter in addition to attaching it to the front lid, and to remove dust trapped inside the disposable filter. In order to dispose of the disposable filter together with a portion of the used disposable filter, the disposable filter requires suturing and cutting operations, which makes it inconvenient to use.

An object of the present invention is to be able to use the vacuum cleaner without losing its function even if you forget to attach a disposable filter, and to
To provide a vacuum cleaner with a simple structure and excellent usability, in which attachment and detachment of a disposable first filter can be performed hygienically and easily.

[Means for solving problems]

The above problems are solved by the first filter, which is formed in a bag shape in advance and can be disposed of while storing the captured fine dust, and the first filter, which has shape retention properties and can trap fine dust, and can be used repeatedly. A second filter to be used is installed in the dust collection chamber in the order of the first filter and the second filter from the upstream side, so that the first filter removes dust that has flowed in from the suction port leading to the dust collection chamber. The dust is captured and removed together with the first filter from the dust collection chamber and disposed of, and when the first filter is not installed in the dust collection chamber, the dust flows in through the suction port leading to the dust collection chamber. This problem can be solved by configuring the second filter to trap both the fine dust and coarse dust that have been generated in the dust collection chamber.

[Effect]

If a vacuum cleaner user uses a disposable filter,
Even if you forget to install the filter in the dust collection chamber, both fine dust and coarse dust will be captured by the second filter, and the function of the vacuum cleaner will not be lost. Furthermore, since the disposable filter is the first filter formed into a bag shape in advance, there is no need for suturing or cutting of the disposable filter.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail based on the drawings showing one embodiment.

In the drawings, 1 is a main body case of the vacuum cleaner, which is made of a material such as synthetic resin or steel plate, and includes a main handle 2. Code exit 3. A receiving portion 4, a hooking portion 5 for the case clamp 13, and the like are provided.

Further, the dust collection chamber 10a is provided with a first opening 10b in a portion different from the second opening 10c.

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

On the other hand, a lid 18 is provided on the first opening 10b of the dust collection chamber 10a. The rotation shaft portion 14 for the lid body 18 and the hook portion 15 are provided in the dust case 10.

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

The first opening 10b of the dust collection chamber 10a has an opening 10 therein.
A lid body 18 for closing the dust case 10 is pivotally supported by the rotating shaft portion 14 of the dust case 10, and is attached to the dust case 10 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 dust case 10, and furthermore, the lid cover 21 is attached to a screw 22.
A lid gasket 23 for keeping the first opening 10b airtight is attached.

The lid body 18 includes a hose, an extension pipe, a suction port, etc. (not shown).
A suction port 24 for sucking in dust is provided by connecting the two, and a first filter packing 25 is disposed at the suction port 24.

The lid cover 21 is provided with a first filter engaging/disengaging device 26 for setting and removing a disposable first filter 27 so as to communicate with the suction port 24.

The first filter 27 has a paper bag portion 27a formed in advance into a bag shape using filter paper or the like, and the first filter 27 is connected to the first filter provided on the lid cover 21 of the lid body 18 at the entrance portion of the paper bag portion 27a. A locking piece 28 that communicates with the suction port 24 by the removal device 26 and is held airtight by the first filter packing 25 is fixed by a method such as adhesion or welding.

Therefore, the first filter 27 can be engaged or detached by the locking piece 28.
This can be easily done by holding and removing the part of the first filter engaging/disengaging device 26.

The second filter 29 is the second opening 1 of the dust case 10.
It is detachably attached to the 0c side and is located downstream of the first filter 27, so that fine dust can be captured and it can be used continuously without being replaced.

In this embodiment, the second filter 29 includes a fine filter 30, a coarse filter 31, and a fine filter 3.
a dust removal device 32 that serves to remove dust that has adhered to
These parts are combined to create a second opening 10c of the dust collection chamber 10a.
It is composed of a filter packing 33 that can be attached to and detached from the body and that serves to keep it airtight.

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

It is composed of a coarse filter 31, a coarse dust filter 36 made of a wire mesh 9, a synthetic resin net, etc., and a frame 37 for maintaining the shape of the coarse dust filter 36.

The dust removal device 32 includes the filtration section 3 of the fine filter 30 described above.
This is a device that removes the dust that has clogged the air conditioner by applying vibrations by hitting or rotating and sliding.It is a device that can selectively adopt various methods that are currently generally known as necessary. be.

The auxiliary coarse filter 38 is installed all around the inner surface of the dust collection chamber 10a, and is used for coarse dust filtration.
9 and a shape-retaining frame portion 40.

This auxiliary coarse filter 38 is arranged so as to have a minute interval from the inner circumferential surface of the dust collecting chamber 10a, and can sufficiently withstand wind pressure caused by air flow, and has an air passage between it and the inner circumferential wall of the dust collecting chamber 10a. It is arranged so that it has.

In this embodiment, an example in which the auxiliary coarse filter 38 can be separated from the coarse filter 31 is described.
Although an example has been described in which the filters are arranged all around the inner peripheral surface of the dust collection chamber 10a, this configuration is not limited to this, and for example, only the coarse filter 31 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.
The above-mentioned air passage is formed by a separate peripheral structure, by providing ribs on the opposing wall surface to be in contact with, or by making the wall surface have an uneven structure, and also allows the first filter 27 to adhere to the wall surface as described below. can be prevented.

Note that the reference numeral 41 in the figure indicates dust.

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

First, as shown by the arrow in FIG. 1, when an airflow containing dust etc. flows through the suction port 24, the airflow flows into the first filter 27 which is set in communication with the suction port 24.

At this time, the first filter 27 inflates like a balloon due to the pressure of the air flow and the pressure caused by the collision of the sucked dust, etc., but if the first filter 27 is allowed to inflate freely without restrictions, the first filter 27 27 ruptures and ceases to function as a filtration filter, but in the structure described above, the coarse filter 31 and the auxiliary coarse filter 38
However, it serves to suppress the swelling of the first filter 27 to a small extent and prevent it from bursting.

When the first filter 27 expands, the coarse filter 31 and the auxiliary coarse filter 38 completely adhere to the wall of an impermeable object such as the dust collection chamber 10a, and the air permeability of the first filter 27 in the close contact portion In this regard, as mentioned above, the same effect can be expected by configuring the coarse filter 31 as a separate periphery, or by providing wall helices or irregularities. It is something.

Therefore, the first filter 27 is the coarse filter 3
1 and the auxiliary coarse filter 38, the suction port 2
The dust flowing in from the first filter 27 can be filtered, and the dust 41 shown in FIG. 1 is collected in the first filter 27.

The clean air that has passed through the first filter 27 is filtered through a coarse filter 31 as shown by the arrow in the figure. It passes through a fine filter 30, passes through an electric blower 6, and is discharged to the outside from the main body case 16. In other words, when used in the manner shown in FIG. 1, the coarse filter 8 in this embodiment is used.
1 is.

It serves to protect the strength of the first filter 27 and maintain the air passage, and together with the fine filter 30, it does not function as a filtration filter.

When the first filter 27 is full, the dust 41 captured in this way is transferred to the lid 18 as shown in FIG.
The user can open the lid by operating the lid clamp 19, remove the first filter 27 by operating the first filter locking/disengaging device 26, and throw it away together with the first filter 27 in a trash can or the like. At times, the dust can be disposed of in a very hygienic manner without seeing the accumulated dust or being covered in dust when disposing of the dust.

Furthermore, by discarding the first filter 27 clogged with dust 41 and installing a new spare first filter 27, the vacuum cleaner will once again exhibit the same suction performance as a new one, unlike conventional filters that can be used repeatedly. Compared to vacuum cleaners that use only vacuum cleaners, it maintains better performance and eliminates the hassle of cleaning filters.

By the way, since the first filter 27 is disposable, if the first filter 27 becomes full during cleaning and you don't have a spare, or if you forget to buy a spare, use a vacuum cleaner. Not being able to use it is inconvenient.

However, according to the present embodiment, as shown in FIG. After filtering out the coarse particles, the fine dust (sand, dust, etc.) is captured by the fine filter 30, and the dust 41 is directly accumulated in the dust collection chamber 10a. When disposing of the dust, as shown in FIG. All that is required is to remove the dust case 10 side by operating the case clamp 13, take out the second filter 29, and throw away the dust 41 accumulated in the dust collection chamber 10a.

As described above, according to the present embodiment, as a result, the first opening IQb and the second opening IQb provided in the dust collection chamber 10a are
By arbitrarily opening either one of the openings 10c, different filtration filters, i.e.,
Dust treatment can be performed using either the first filter 27 or the second filter 29.

In each case, it is only necessary to remove either the case clamp 13 or the lid clamp 19, and compared to the conventional case in which both clamps 13 and 19 are removed, Its usability is far superior.

In this way, the first filter 27 is easily damaged by inconvenient dust, such as metal pieces, nails, and rivets, no matter how protective the guard is.
On the other hand, in the case of dust that is not suitable for the second filter 29, such as dust with a lot of fine dust that is difficult to dispose of and that tends to form lumps, the first filter 29
It is an easy-to-use vacuum cleaner that can be used selectively on a case-by-case basis, such as collecting dust with a vacuum cleaner and disposing of it in a sanitary manner.

Since the dust captured by the first filter 27 accumulates in the paper bag 27a of the filter 27, the lid body 18
Just open it, take out the first filter 27, and throw it away together with the first filter 27. There is no need to worry about cleaning the filter, and you can simply install and replace the spare first filter 27, making it as good as new. You can start cleaning with its suction performance.

In addition, when there is no spare first filter 27, or when filtration is performed using the reusable second filter 29 due to some reason, such as the type of object to be cleaned or the type of dust, the current method is generally Similar to known vacuum cleaners, 10 parts of the dust case are separated from the main body case 1.
After removing the second filter 29 from the side and operating the dust removal device 32 to remove dust from a portion of the clogged fine filter, the second filter 29 is pulled out from the dust collection chamber 10a.

The dust accumulated in the dust collection chamber 10a can be disposed of in a trash can or the like, and dust treatment can be performed in exactly the same manner as a conventional vacuum cleaner.

In any of the above cases, it is sufficient to open the lid 18 or remove the dust case 10 from the main body case 1 side, which provides good operability overall. It is.

In this embodiment, a paper bag made of paper such as filter paper has been described for the disposable first filter 27, but the material is not limited to paper, and any material that is economical may be used. For example, the use of any material that does not impair its functionality is not prohibited.

〔Effect of the invention〕

As described above, according to this method, the following effects can be expected.

(1) The dust trapped in the first filter, which is pre-shaped into a bag, can be removed from the dust collection chamber and thrown away together with the first filter in a trash can, etc., without getting your hands dirty. You can perform dust removal work in an extremely hygienic manner without creating any lumps.

(2) If you forget to install the disposable first filter in the dust collection chamber, or if you forget to buy a disposable first filter, you do not have a spare first filter, and you do not have the first filter in the dust collection chamber. Even if it is not possible to install a second
Since both fine dust and coarse dust can be collected in the dust collecting chamber by the filter, cleaning work can be carried out without any hindrance, making it extremely easy to use.

(3) The disposable first filter is formed into a bag shape in advance, and it can be simply installed as it is on the upstream side of the dust collection chamber. It is extremely easy to use since there is no need to create a complicated structure for making a filter, and there is no need to cut or weld the first filter.

(4) Just by discarding the first filter installed in the dust collection room and replacing it with a new one, you can start cleaning with the same suction performance as a new one without having to remove dust from the second filter. .

(5) The shape-retaining second filter can suppress swelling of the first filter and prevent the first filter from bursting.
