Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of Chestnut] The present invention relates to a vacuum cleaner, and particularly to a suction port body thereof.

[Conventional technology]

The electric cleaner e uses the electric blower on the 9 main units to suck in air and dust from surfaces to be cleaned such as floors, etc. from the suction port body.
Cleaning is performed by accumulating this dust, etc. in the dust collection chamber≦2. If the floor surface is covered with paper, it may be difficult to remove the adhering dust, and as a countermeasure, the suction port body has a function to remove this dust. FIG. 4 is a partial cross-sectional view of a vacuum cleaner of this type shown in Japanese Patent Publication No. 61-52687, viewed from the bottom surface of the suction port body.

In the figure, (IIH suction port body, (2) is connected to this suction port body +11, and is a suction pipe through which suction air passes.

(3) C) A suction port opening on the lower surface of the above-mentioned suction body +1;
), (5) is the shaft of this turbine (4), (6) is installed in the suction port body (1), and from this shaft (5) to the belt (7). A rotating brush (8) rotated by the rotational force transmitted by the turbine (4) is a partition wall of the turbine (4).

J to a conventional vacuum cleaner? The suction port body has the C2 structure as described above, and during operation, the suction port (3) of this suction port body slides into contact with the surface to be cleaned.

The suction force of the electric blower of the vacuum cleaner body (not shown) is transmitted to the suction port (3) through the suction pipe (2).

Air and dirt adhering to the sea cleaning surface are sucked in from the suction port (3), and the air flow generated at the opening of the suction pipe (2) causes the turbine (4) in the partition wall (8) to rotate at high speed. This rotational force is transmitted to the rotating brush via the detail (5) and the belt (7), causing it to rotate. In particular, when cleaning dust, etc., this rotating brush (6) rotates, scrubs the carpet surface, and vibrates, so it is very effective in catching dust, etc.

In the suction port body of this ridge, when the suction port (3) is removed from the cleaning surface during cleaning, the single rotation brush (6) becomes unloaded, so the rotation of the turbine (4) and the rotating brush (6) In response to this situation, the number of airflow increases abnormally and the noise becomes louder.In response to this problem, the partition walls (8), etc. are made more complex to adjust the airflow, and airflow adjustment valves and switching levers are installed. This is used as a counterpoint to the problem.

[Problems to be Solved by the Invention] Although the suction port body of the conventional vacuum cleaner as described above can remove dust attached to [A, etc.], there is a turbine (4) in this suction port body.

It is necessary to store parts such as the rotating brush (6) and the belt (7), which makes the suction port large and heavy. Furthermore, if various parts are mounted to prevent the above-mentioned noise during no-load operation, the device will become even heavier. Therefore, problems have arisen in that regular operation of the suction port body by the user becomes labor intensive, and cleaning of corners and gaps on the floor surface becomes difficult.

In addition, although this suction port body is effective in cleaning paper types, etc., rubbing the carpet surface with a brush may cause fuzzing and deterioration of the bristle surface, and furthermore, it may cause cleaning of hard materials. It is unsuitable for cleaning floors and places with many uneven surfaces because the brush cannot reach the recessed parts, and it has several problems such as the suction opening being less versatile.

In order to solve the problems of the present invention, it is an object of the present invention to obtain a vacuum cleaner having a compact suction port body and good dust collection performance.

[Means for solving problems]

The electric vacuum cleaner according to the present invention is provided with a nozzle for air blowing which is opened around the suction port in the suction port body for sucking in air and the like, and a feeding means for feeding air to the nozzle for this blowing. It is something that

[For production]

In this invention, the air sent from the feeding means is blown outward from the suction port by a nozzle, and the dust adhering to the surface to be cleaned is separated from the surface. It is sucked from the suction port.

It is sucked in from the suction port (3) through the suction pipe (2), and the collection I
I filter +15 and exhaust port a9. The air is blown out from the nozzle a through the circulation air path and the feed pipe αυ. Spraying is done through a nozzle (the tip of the IG is constricted, so the flow rate of air blowing out from here is fast. In this state, when the suction port (3) and brush (9) of the suction port body are moved in sliding contact with the surface to be cleaned, After the dust adhering to the cleaning surface is blown away by the air from the nozzle (IG), it is sucked in with the air from the suction port (3), and collected in the collection filter O5 of the dust collection chamber α3. This allows for effective cleaning.

In addition, by operating the heater cllυ, the air blown out from the nozzle Ql can be heated to a high temperature.
It is possible to kill the mites that live in large numbers, and these dead mites are also sucked in through the suction port (3).

In addition, in this vacuum cleaner, if the outside air inlet (2) is closed using the suction opening/closing valve @ and the exhaust opening opening/closing valve (2), and the outside air outlet (toward) is opened, the dust collection chamber α3 can be
The air flowing into the room σ is exhausted to the outside from the external exhaust port (to) and does not flow to the circulation air path ■. In this case, the air will not blow out from the nozzle (1), but the air will flow more easily and the suction force of the suction port (3) will increase.

It is effective when the dirt on the surface to be cleaned is relatively large and the adhesion force is small. At this time, heater CL is turned off. Further C2, conversely, close the outside air intake port (2) and close the outside air exhaust port (2).
When the chamber (2) is closed, the air flowing into the blower chamber (2) will not pass through the suction pipe (2), which has a large air resistance, and the fruit dust filter α9, and will be taken in as outside air.

Pass through entrance (2). This air passes through the circulation air path ω and is blown out from the nozzle αG, so the blown air blows away dust that has accumulated in the gaps and corners of a room, and then it is sucked in by the suction operation described above. Can be done.

At this time, the blown air becomes warm air due to the heater υ, so that it can be used as a drying device by inserting another attachment into the tube insertion port aη.

Spraying is more effective than suctioning to remove dust attached to the cleaning surface, and there is no need to rub the cleaning surface with a rotating brush, so there is no damage to the cleaning surface. It can also clean dust adhering to walls, floors, and interior decoration items. In addition, since the suction port body is only provided with a nozzle Ql for spraying, it is smaller and lighter than the conventional one.

In the above embodiment, the suction opening/closing valve @ and the exhaust opening/closing valve (c) are manually operated, but they may be linked and automatically opened/closed using a selection switch. It is also possible to perform actions such as intermittent blowing. In addition, the outlet of the nozzle for spraying may be provided around the center of the suction port, but rarely at the periphery of the suction port. Furthermore, although an electric blower was used to supply air to the nozzle in order to obtain a suction force, a separate electric blower may be provided.

〔Effect of the invention〕

As explained above, this invention is provided with a nozzle for air blowing that opens toward the suction port in the suction port body that sucks glands, etc. together with air, and a feeding means for feeding air to the nozzle. This has the effect of providing a small and lightweight suction port with good dust collection performance, which can be cleaned over a wide range of areas, and is easy to use.
