Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner incorporating an electric blower.

Conventional configurations and their problems Traditionally, vacuum cleaners have been divided into the clean fan type, which has a filter on the intake side of the electric blower to capture dust, and the dirty type, which has a filter on the exhaust side of the electric blower to capture dust. -There were fan types. Among these, in the case of the clean fan type, the air flow concentrates on the electric blower, so it is easy to get clogged even if the filter area is large, and in the case of the tertiary fan type, the air flow is dispersed. Therefore, the larger the filter area, the less likely it will become clogged.

However, in the case of the tarty fan type, dust passes through the fan, making it loud and having the disadvantage that the fan is easily broken.

Purpose of the Invention The present invention solves the above-mentioned problems and uses an electric blower to temporarily capture dust in a temporary dust collection section corresponding to an intake port, and then captures dust from the temporary dust collection section corresponding to an exhaust port into a dust collection bag. In this way, the present invention aims to provide a vacuum cleaner with less clogging of the filter and excellent dust suction action.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a drum-shaped filter that covers the outer peripheral surface of a main body containing an electric blower and is rotatably provided, and a drum-shaped filter that is in contact with the inner wall surface of this filter and that is connected to the electric blower. Consisting of an intake port and an exhaust port provided so as to communicate with each other, an outer circumferential surface and a side dust portion of the filter, and a dust collection bag removably provided at a position facing the exhaust port via the temporary dust collection portion. 1 was a vacuum cleaner.

The main unit with an electric blower is located inside a rotatable drum-shaped filter, and after the suction force of the electric blower causes dust to adhere to the filter in the temporary dust collection section, the dust attached to the filter is removed by the exhaust of the electric blower. It is blown away and captured in a dust collection bag, so there is less clogging of the filter.
This allows for efficient cleaning.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 1 to 5, 1 is a vacuum cleaner body, which is a drum-shaped vacuum cleaner that houses an electric blower 2 and a rechargeable battery 3, covers a central ventilation passage 4 and its outer circumferential surface, and is rotatably supported. It is equipped with a filter 5.

The central ventilation passage 4 has an intake port 6 communicating with the intake side of the electric blower 2 at the lower part, and forms an exhaust lower at the upper front part. Reference numeral 8 denotes left and right bearing materials to which the filter 5 is fixed, and an elastic roller 9 formed in a ring shape on the side surface of the left and right bearing materials 8, and this roller 9 is divided at equal intervals, and the left and right rollers and the above-mentioned It has a lip 10 that is in close contact with the filter 5 and has an i-type material. 11 is a hook formed at the tip of the lip 10. The filter 5 is rotatably supported by being attached to shaft portions 12 formed at the left and right ends of the central ventilation passage 4 via left and right support members 8 .

Reference numeral 13 denotes an intake rib, which forms a suction port 14 that communicates with the intake port 6 and is in contact with the inner wall of the filter 5 described in 1. Reference numeral 15 denotes an exhaust rib, which forms an exhaust port 16 and communicates with the exhaust lower.

The tip thereof contacts the inner wall of the filter 5 similarly to the intake rib 13 described above. 17 is a handle, which is attached to the shaft portion 12 of the central ventilation passage 4;
A grip 1!3 with a switch 18 attached is fixed to the upper end.

A lead wire 20 is connected from a lead wire passage 21 provided at the upper part of the central ventilation passage 4 to the shaft portion through the inside of the handle 17 and connected to the swifter 18. A cover 22 is fixed to the handle and is composed of an upper member 22a and a side member 22b.

A seal 23 is attached to the inner wall of the upper member of the cover 22 and performs air tightness between the roller 9 and lip 10 of the filter 5 and the upper member of the cover 22. A dust collection bag insertion frame 24 is integrally formed at the tip of the cover 22, and the dust collection bag 25 is fixed to the main body l by inserting the mouth core 26 of the dust collection bag 25 from the side.

27 is a stopper, and 28 is an opening of the mouth core.

28 is an outlet, and a power cord for charging (not shown)
can be detachably connected to the rechargeable battery 3.

Reference numeral 30 denotes a temporary dust collecting section, which is formed by the lip 10 adjacent to the outer peripheral surface of the filter 5. 31 indicates dust.

The filter 5 has a width corresponding to the suction port 14 that communicates with the intake port 6 of the electric blower 2, and is separated by a lip 10 so as to correspond to the exhaust port 1s.

In the above configuration, when the electric blower 2 is operated, suction air passes between the lips 10, filters out dust by the filter 5, passes through the suction port 14 and the intake port 6, and reaches the electric blower A machine 2. Exhaust air from the electric blower 2 passes through the exhaust port 16 from the air loss lower, passes through the filter 5 again, and enters the dust collection bag 2.
It is discharged within 5 days. Then, it passes through the blood collection bag 25 and is discharged to the outside.

As shown in Figure 5, the dust on the surface to be cleaned is removed by the electric blower 2.
Due to the suction force, the dust is temporarily collected in the temporary dust collecting section 30 formed by the roller 9, the lip 10, and the filter 5, and when the main body 1 is pushed forward in this state, the filter 5 rotates in the direction of the arrow. Dust 31 accumulated in the temporary dust collecting section 30 is scooped up by the lip 10. Furthermore, rotate the filter 5.

When the temporary dust collection section 30 comes to the position of the discharge port 1B, the dust 31 accumulated in the temporary dust collection section 30, including the fine dust attached to the filter 5, is removed by the exhaust gas that passes through the filter 5 and is removed from the temporary dust collection section 30. The dust is blown out from the dust collecting section 30. At this time, since the exhaust passage force is suppressed by the cover 22 - upper member and side part and gasket (23 and 0-ra 9 and lip 10), the blown out dust is removed from the opening of the dust collection bag 25. It enters from the opening 2 of 2B and reaches the inside of the dust collection bag 25.Then, the dust is filtered by this dust collection bag 25, and only clean air is discharged to the outside.A hook 11 is provided at the tip of the lip lO. In this case, the temporary dust collection section 30 can more reliably capture dust.

By rotating the filter 5, the above operation is performed continuously between the lips 10, thereby cleaning the surface to be cleaned.

If the area of the discharge port 16 is made smaller than the area of the suction port 14, the passage speed of the exhaust gas through the filter 5 will be faster, the filtration by the filter 5 will be complete, and the filter itself will be cleaned.

Effects of the Invention As described in (1) above, according to the present invention, cleaning can be performed by the conventional operation of pushing the main body, and the dust is temporarily captured in the temporary dust collection part formed by the roller, lip and filter, and the dust collection is performed. Dust is dispersed and transferred to the dust collection bag at the opening of the mouth core where the bag is attached and the corresponding exhaust port, so the filter is constantly cleaned by exhaust air, so there is no clogging, and strong suction power is always maintained. Now you can. Furthermore, since dust does not pass through the fan of the electric blower, the noise is low and the fan will not break.Also, since the airflow is dispersed at the opening in the mouth core, dust will not be blown into the dust collection bag. The area of the dust collection bag can be fully utilized. Moreover, since the exhaust air is dispersed over the entire area of the dust collection bag, the exhaust speed is reduced and dust is no longer blown away by the exhaust air.

Noise is also reduced because the electric blower is inside the filter.

In addition, in the present invention, there is no need to attach a hose, extension pipe, or floor nozzle, so there is less pressure loss at these parts, and even a small electric vacuum cleaner powered by rechargeable dry batteries can be used as a vacuum cleaner. It is possible to obtain a compact, lightweight, and high-performance vacuum cleaner with almost the same cleaning ability.

Furthermore, since there is no clogging, there is no need to remove dust.
Also, if a disposable paper bag is used as a dust collection bag, maintenance such as garbage disposal will be much easier.

In addition, since it can be used without a hose or extension tube, it can be used immediately when cleaning, and since it can be used with rechargeable batteries, you can clean without dragging the power cord around.

In addition, although a rechargeable dry cell battery was used as a power source in the example,
It goes without saying that a normal ACi source may be used and the above effects other than the power cord can be obtained.

In this embodiment, the filter is rotated manually by pushing the main body, but even if the filter is rotated electrically, there is no problem and the same excellent effect is obtained.
