Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a vacuum cleaner that uses a disposable paper bag dust collector for easy and sanitary garbage disposal.

(b) Conventional technology Conventionally, in this type of vacuum cleaner, a disposable paper bag dust collector with a filter function is installed in the dust collection chamber so as to communicate with the air intake port to collect dust, and after dust collection, the paper bag is used to collect dust. Since the dust collector can be removed and the paper bag dust collector can be disposed of as garbage, the filter part is always new, which has the advantage of maintaining strong dust suction power and making it possible to dispose of garbage in a sanitary manner. However, if you forget to attach the paper bag dust collector to the intake port of the dust collection chamber before cleaning, the electric blower will suck in the dust directly, which will not only cause the vacuum cleaner to malfunction, but also prevent normal cleaning. The disadvantage is that it cannot be done. Vacuum cleaners that solve this drawback are disclosed in, for example, Japanese Utility Model Application Publication No. 53-98766 and Japanese Utility Model Application Publication No. 52-41167. However, the cloth bag used to store the paper bag dust collector disclosed in these vacuum cleaners does not have shape retention properties and is deformable, so when an electric blower is activated to collect dust, the cloth bag (at least a part of it) ) It comes in close contact with the wall of the dust collection chamber of the main body, which impairs ventilation and reduces dust collection performance.Furthermore, the cloth bag is difficult to hold when disposing of garbage, and when pressed or grabbed, it deforms and dust comes out and spills out. There is a drawback. In addition, in these conventional examples, it is necessary to open and close the front cover provided on the front of the vacuum cleaner body to store or discharge the dust, making it difficult to attach or remove paper bag dust collectors or cloth bags from the dust collection chamber. This becomes extremely troublesome and has poor usability.

In addition, a vacuum cleaner in which a top-opening dust collection chamber is formed in the front part of the main body case and a bag-shaped filter is disposed is also disclosed in Japanese Utility Model Application Publication No. 52-27176. If you forget to attach it, dust will be collected in the dust collection chamber.
When discharging the dust after dust collection, the main body case must be carried to a garbage disposal site for disposal, which is also extremely difficult to handle.

On the other hand, in vacuum cleaners that use a filter device that combines a reusable cloth bag filter or net filter with a shape-retained filter paper filter, it is necessary to remove dust from the filter as appropriate, and waste disposal after dust collection is also troublesome. It is unhygienic.

(c) Purpose of the invention The present invention eliminates the above-mentioned drawbacks, and is capable of fully demonstrating the characteristics of a disposable paper bag dust collector and a reusable filter, as well as being hygienic and easy to handle. Moreover, it is an object of the present invention to provide a vacuum cleaner in which the versatility of the paper bag dust collector is improved.

(d) Structure of the invention The vacuum cleaner of the invention has a dust collection chamber with an opening on the top formed in the front part of the main body case which houses an electric blower in the rear part, and a box-shaped filter with an opening on the top in the dust collection chamber. A lid plate is provided that is removably arranged and closes the upper opening of the dust collection chamber, and the opening of the paper bag dust collector stored inside the box-shaped filter is connected to the opening of the box-shaped filter. The paper bag dust collector is supported through the mounting frame, and the cover plate has an intake port communicating with the paper bag dust collector. By supporting the opening of the box-shaped filter, it is stored inside the box-shaped filter,
This box-shaped filter is removably installed in the dust collection chamber.

(e) Embodiment 1 is a main body case with moving wheels 2 on the front bottom and rear wheels 3 on both sides of the rear, and the case has ventilation holes 4,
The device storage chamber 7 is divided into an equipment storage chamber 7 in which an electric blower 6 and a cord reel (not shown) are housed, and a dust collection chamber 9 having an opening 8 on the top surface, by a partition plate 5 having 4... Reference numeral 10 denotes a shape-retaining box-shaped filter disposed in the dust collecting chamber 9, and a disposable paper bag dust collector 11 with air permeability is housed in the filter, and the bag opening 12 of the dust collector is similar to the one described above. filter 10
The opening edge 13 is bent and locked.

Reference numeral 14 denotes the paper bag dust collector 11 placed on the upper opening edge 15 of the dust collection chamber 9 via a gasket 16.
An annular inner rib 17 and an outer rib 18 for sandwiching the bag opening 12 of the paper bag dust collector 11 are formed on the back surface of the mounting frame plate 14, and an annular inner rib 17 and an outer rib 18 are formed. A plate spring 19 is provided at the. Note that the outer rib 1 is used instead of the leaf spring 19.
A similar effect may be achieved by providing an appropriate number of protrusions on the inner surface of 8.

20 is an intake port 2 that is opened and closed by a check valve 21;
2 is positioned so as to close the upper surface opening 8 of the dust collection chamber 9 via the mounting frame plate 14, and the rear end protrusion 23 is locked to the engagement portion 24 of the main body case 1. At the same time, the front end portion 25 is removably locked by a clamp hook 26 provided at the front portion of the main body case 1. Further, an opening 28 is provided on the bottom surface of the cover plate 20 facing the communication port 27 of the mounting frame plate 14, and a check valve 21 is provided at the intake port 22, and a shutter plate 29 for opening and closing the communication port 27 is provided. They work together.

Next, the operation in the above configuration will be explained.

First, the paper bag dust collector 11 is stored in the box-shaped filter 10, and the bag opening 12 is inserted into the filter 10.
It is bent and locked to the opening edge 13 of. Thereafter, the mounting frame plate 14 is placed on the upper opening edge 15 of the dust collection chamber, and the bag opening 12 is held between the annular inner rib 17 and outer rib 18. Finally, when the cover plate 20 is attached and locked, and the connecting pipe 30 of the suction tool is connected to the intake port 22, the shutter plate 29 opens due to the operation of the check valve 21, and the intake port 22 and the paper bag dust collector 11 are communicated with each other. do.

When the electric blower 6 is operated in this state, the dust 31 sucked in through the intake port 22 accumulates at the bottom of the paper bag dust collector 11. A small portion of the fine dust passes through the paper bag dust collector 11 and is collected by the box-shaped filter 10. At this time, since the box-shaped filter 10 has a shape-retaining property, a gap can be maintained between the wall surface of the dust collection chamber 9 and the box-shaped filter 10, resulting in good ventilation and improved dust collection performance. The combination of the paper bag dust collector 11 and the box-shaped filter 10 improves the filtration performance and ensures reliable dust collection.

After cleaning is completed, when the connecting pipe 30 is removed, the clamp hook 26 is removed, and the cover plate 20 is removed, the communication port 27 of the mounting frame plate 14 is closed by the weight of the shutter plate 29.

Then, when the mounting frame plate 14 is lifted to release the engagement state with the opening edge 13 of the box-shaped filter 10, the paper bag dust collector 11, which was in the state shown by the two-dot chain line in FIG. Inner and outer ribs 17,
It is clamped in 18 and can be taken out together with the mounting frame plate 14. Finally, remove the paper bag dust collector 11 containing the garbage from the mounting frame plate 14 and remove it from the bag opening 12.
It is best to close it and throw it in a trash can.

Further, even if the paper bag dust collector 11 breaks, the dust is collected by the box-shaped filter 10, so that normal cleaning can be performed without any adverse effect on the electric blower 6. In this case, after dust collection, it is preferable to remove the lid plate 20, pull out the box-shaped filter 10 from the dust collection chamber 9 of the main body case 1, and dispose of the dust.

Furthermore, regardless of the shape of the opening of the box-shaped filter 10, the paper bag dust collector 11 can be attached by simply changing the shape of the mounting frame plate 14, which increases the versatility of the paper bag dust collector 11. With,
Since the mounting frame plate 14 can be used repeatedly, only the paper bag dust collector 11 needs to be replaced when disposing of the garbage, thereby reducing the cost of disposing of the garbage.

(f) Effects of the Invention The vacuum cleaner of the present invention is constructed as described above, and in particular, a box-shaped filter is detachably stored in the dust collection chamber with the top open, and a paper bag dust collector is stored inside the box-shaped filter by supporting its mouth on the opening of the box-shaped filter via a mounting frame, so that it has the following effects.

In order to make waste disposal more sanitary, we collect dust using a disposable paper bag dust collector, and also have a dust collection function using a box-shaped filter that can be used repeatedly.
Filtering performance can be improved by combining two filters. Moreover, the filtration performance of each filter can be fully demonstrated.

Since the paper bag dust collector and the box-shaped filter can be taken in and out of the dust collection chamber through the top opening, it is easy to dispose of the dust.

Because it is a box-shaped filter with shape retention,
Since a gap can be maintained between the wall surface of the dust collection chamber and the box-shaped filter, dust collection performance is improved, and since the box-shaped filter is not deformed during garbage disposal, dust does not fall out and garbage can be disposed of in a sanitary manner.

The opening of the paper bag dust collector is supported through the mounting frame at the opening of the box-shaped filter, so no matter what shape the opening has, it can be accommodated by simply changing the shape of the mounting frame. Increases versatility.

Since the mounting frame can be used repeatedly, only the paper bag dust collector needs to be replaced when disposing of the garbage, thereby reducing the cost of disposing of the garbage.
