[Technology Background]

The present invention relates to a vacuum cleaner for sucking dust using a suction fan by using a motor as a motive force, and a strong air wind generated in a suction fan is used. Especially, a strong air wind which is unnecessarily wasted is circulated and reused, To a vacuum cleaner for air circulation that doubles the power to remove, improves the ability to clean while saving electricity, and recovers secondary contamination by a vacuum cleaner.

[0003]

Conventional vacuum cleaners use only one of suction force for sucking dust generated in a suction fan or air wind blowing dust, and most of them use only suction force. Such conventional techniques have various problems, among which the second is the secondary contamination by the vacuum cleaner. In the conventional vacuum cleaner, the suctioned dust is filtered by the paper filter, but some minute dust passes through the paper filter. The fine dust that has passed through the paper filter passes through the suction fan, the motor, and finally gets filtered out of the exhaust filter, mostly coming out of the vacuum cleaner and polluting the room again.

In addition, since the conventional vacuum cleaner uses only one suction force for sucking dust generated from the suction fan or air blowing dust, And the suction force generated from the suction device during the cleaning process on the floor plate or the carpet laid on the floor to be cleaned is all vertical to the floor so that the suction force of the dust adhered to the suction device There is a disadvantage in that it is deteriorated or adhered to the inhaler to clean. In this case, in order to maintain the same inhalation ability, there is a disadvantage that the equivalent electric energy must be consumed.

Some of the improvements of the conventional technique are disclosed in Japanese Laid-Open Patent Publication No. 31-62814. The key point of this technique is that air wind generated from the suction fan is partially used for cooling the motor, To blow out the dust and suck it into the inhaler to improve the cleaning ability. However, there are many problems in using this technique. Since a part of the air wind generated from the suction fan is used to cool the motor and then goes out of the vacuum cleaner body, fine dust passing through the paper filter is sucked into the suction fan, , There is still a problem of being discharged out of the vacuum cleaner through the outlet to cause secondary contamination.

In addition, since this technology is a one-piece type in which the suction unit and the cleaner main body are attached to each other, it is necessary to move the cleaning main body in a desired direction when cleaning. Therefore, in order to make it easier, A device and a control device are required. Further, the electric energy required for driving is required, and the control device must be operated every time the cleaning direction is changed. In addition, since the vacuum cleaner body can not be entered into a corner, a narrow space, a gap, a bed, or a curtain, it is necessary to use a separate small vacuum cleaner or an inhaler composed of only a separate suction port There is a disadvantage that cleaning efficiency, electric energy saving, convenience of use is not improved.

Thus, the conventional technique uses only one of the suction force of the suction fan or the air wind to generate secondary contamination due to fine dust discharged to the outside of the vacuum cleaner, to pull out the carpet, carpet, curtain or the like, Deterioration of cleaning ability and inconvenience, overuse of electric energy and deterioration of efficiency, and the technique disclosed in Japanese Patent Application Laid-Open No. 316-2814 also has a problem of occurrence of secondary pollution, , The need for an inhaler or a small vacuum cleaner, the consumption of electric energy for the driving device, and the deterioration of the cleaning ability due to the disadvantages thereof, and inconvenience to operate the adjusting device, a corner or a narrow place, a gap, It is troublesome to use a separate small vacuum cleaner or to use an inhaler comprising only a separate suction port.

[Object of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vacuum cleaner in which an air blower having the same force as a suction force generated in a suction fan of a vacuum cleaner is not discharged to the outside through a discharge filter of a vacuum cleaner, The dust is blown out to the suction port of the suction device, and the suction force of the suction port is used to suck the dust, thereby reducing the secondary contamination by not discharging the fine dust generated in the cleaning process to the outside of the vacuum cleaner And the suction force for sucking dust is simultaneously generated by the air wind blowing dust from the inhaler, thereby doubling the ability to remove dust, and at the same time, the suction force generated perpendicularly to the floor is relatively reduced, , Curtains and so on do not stick to the inhaler to improve cleaning ability Conveniently, it was formed to conserve and improve the efficiency of electrical energy you almost certainly facilitate the cleaning of such inlet and vacuum cleaner to separate them used to connect a hose to a narrow place, a niche, above the bed, curtains.

The blowing pipe 28 of the hose connecting device 12, the blowing pipe 26 of the handle 3, the blowing pipe 24 of the extension pipe 2, and the blowing pipe 14 of the rotary connecting pipe 21 of the inhaler 1, At least one blower support 29 is positioned between these blower pipes 28, 26, 24, 14 and the suction pipes 27, 25, 23, 13 in order to position them in the center of the suction pipes 27, 25, Respectively.

In the air circulation type vacuum cleaner having the above-described structure, the suction force generated in the suction fan 6 inside the vacuum cleaner body 10 acts on the suction pipe 13 of the suction device 1 at the start of cleaning, The extension pipe 2, the handle 3, the suction hose 19 and the suction pipes 23, 25 and 27 of the hose connecting device 12 through the suction pipe 13 of the suction device 1 to reach the paper filter 5 . The air that has passed through the paper filter 5 and arrives at the suction fan 6 is transformed into a strong air wind due to the strong rotational force of the suction fan 6 and is blown into the air blowing chamber 7, the connecting pipe 8, The blowing tube 14 and the spraying tube 22 of the inhaler 1 are finally blown through the blowing tube 28, the blowing hose 18, the handle 3 and the blowing tubes 26 and 24 provided in the extension tube 2, And the jetting port 31 to blow out the dust. The dust blown by the air blown from the spray tube 22 is sucked into the suction pipe 13 of the suction device 1 by the suction force generated in the suction pipe 13 of the suction device 1. [

The blowing pipe 28 of the hose connector 12, the blowing pipe 26 of the handle, the blowing pipe 24 of the extension pipe, and the blowing pipe of the rotating connection are respectively located at the center by the blowing pipe support 29 as shown in FIG. 8 And the blowing hose 18 is located in the suction hose 19 so that the blowing hose 18 is positioned at the center of the suction hose 19 as shown in FIG.

A cooling fan 16 is provided between the motor 9 and the discharge filter 11 so as to cool the motor 9 so that the cold air outside flows through a part of the discharge filter 11, The motor 9 is cooled and discharged through a part of the discharge filter 11 by the cooling fan 16.

As described above, the air circulation type vacuum cleaner simultaneously uses the wind blown through the injection port 31 from the spray pipe 22 of the suction device 1 and the suction force generated from the suction pipe 13 of the suction device 1 at the same time when cleaning the dust And the suction force generated perpendicularly to the floor is relatively reduced, so that the long plate, the carpet, the carpet, and the curtain do not stick to the inhaler, thereby improving the cleaning ability and convenience and saving the electric energy and improving the efficiency. And dusts that have passed through the paper filter 5 are reused by the main body 10 of the vacuum cleaner 10. In this case, ), So that secondary contamination is prevented.

[Example]

The operation of the air circulation type vacuum cleaner constructed as described above will be described with reference to the accompanying drawings.

2, when the air sucked with the dust by the force of the suction fan 6 passes through the paper filter 50 and the dust box 17 and reaches the suction fan 6, It turns into a strong air wind.

The conventional vacuum cleaner uses the air wind to cool the motor 9 and then discharges the air to the outside of the vacuum cleaner body 10 through the exhaust filter 11 and the exhaust port 15. At this time, One fine dust is discharged to the outside of the vacuum cleaner main body 10 to cause secondary contamination of the room.

However, in the present invention, in order to prevent such secondary pollution and to improve the cleaning ability, in order to use this strong air wind, a ventilation chamber 7 is formed outside the suction fan 6 to store strong air wind And the connecting pipe 8 is formed between the air blowing chamber 7 and the part to which the hose connecting device 12 is connected so that the air wind stored in the feeding chamber 7 passes through the hose connecting device 12 to the hose 4, ).

A blowing pipe 28 is additionally formed at the center of the hose connector 12 of the conventional vacuum cleaner and is supported and supported by a blower support 29 so that air blowing from the connecting pipe 8 is blown into the blowing pipe 28 A blowing hose 18 is formed at the center of the suction hose 19 and is positioned at the center of the suction hose 19 by using a plurality of blowing hose support members 30 so that air blowing from the blowing pipe 28 And a blowing pipe 26 and a blowing pipe 24 are formed at the center of the inner side of the handle 3 and the extension pipe 2 to support the blowing pipe 26 and the blowing pipe 24 by the discharge pipe support base 29, .

As shown in FIGS. 3 and 4, the inhaler 1 includes a rotary connection pipe 21 for connecting the extension pipe 2 and the inhaler 1, an upper case (not shown) for sucking dust while forming an outer appearance of the inhaler 1 20), and a spray tube (22) blowing dust by blowing air air.

A blowing pipe 14 for blowing air to the spraying pipe 22 is installed at the center of the inside of the rotary connection pipe 21 and is installed at the center by supporting the blowing pipe support 29, The central portion of the rotary connection pipe 21 is configured to be brought into close contact with the outlet portion of the blowing pipe 14 of the rotary connection pipe 21 in order to receive air wind from the blowing pipe 14 of the rotary connection pipe 21 without loss. The lower portion of the jetting tube 22 is configured to form a fine jet opening 31 for jetting air wind.

In the air circulation type vacuum cleaner constructed as described above, a process of cleaning the dust when cleaning the dust is as follows.

A strong suction force is generated in the suction fan 6 in which the rotating force of the motor 9 is applied to the suction fan 6 and rotated. At this time, the suction force is transmitted to the dust collecting box 17, the paper filter 5, the suction pipe 27 of the hose connector 12, the suction hose 19, the suction pipe 25 of the handle 3, And is applied to the upper case 20 through the suction pipe 13 of the rotary connection pipe 21 constituting the suction device 1. [ At this time, the dust existing under the upper case 20 of the inhaler 1 is sucked into the upper case 20 by the suction force together with the surrounding air, and the suction pipe 13, the extension pipe 2, The air is sucked by the paper filter 5 through the suction pipe 23 of the handle 3, the suction pipe 25 of the handle 3, the suction hose 19 and the suction pipe 27 of the hose connector 12, Passes through the paper filter 5 and the dust collecting box 17 and becomes a strong air wind in the suction fan 6.

The strong air wind formed in the suction fan 6 is stored and collected in the air blowing chamber 7 and the air blowing pipe 28 of the hose connecting device 12, the blowing hose 18, And finally reaches the spraying pipe 22 through the blowing pipe 26, the blowing pipe 24 of the extension pipe 2 and the blowing pipe 14 of the rotary coupling pipe 21 of the suction device 1, And is blown out of the dust present in the lower portion of the spray tube 22. [0042] As shown in FIG.

Therefore, when viewed from the inhaler 1, the inhaler 1 is provided with a suction force and an air wind having the same force as the suction force is injected to clean the dust, thereby improving the cleaning ability. So as to reduce the force for pulling the bottom plate, the carpet, and the curtain under the inhaler 1, thereby facilitating the cleaning and maintaining the maximum cleaning ability at all times. Also, during air circulation, the fine dust that has passed through the paper filter 5 is not discharged to the outside of the main body 10 inside the main body 10 of the vacuum cleaner, so that secondary contamination due to fine dust is eliminated. In addition, since such a structure is identical to a conventional vacuum cleaner in which the conventional inhaler and the vacuum cleaner body are connected by an extension pipe, a handle, and a suction hose, there is no need to add a separate driving device and a control device for driving the vacuum cleaner body, When cleaning a place, a gap, a bed, a curtain, etc., it is possible to use a separate small-sized vacuum cleaner or to easily clean the vacuum cleaner using a direct inhaler without using an inhaler comprising only a separate suction inlet.

[Effects of the Invention]

According to the present invention configured as described above, since the strong air wind generated after sucking in dust can be used to blow the dust back to the suction unit again without discharging it to the outside of the body of the vacuum cleaner, It is possible to prevent secondary pollution caused by vacuum cleaner because it does not send the air wind mixed with fine dust like vacuum cleaner to the outside of the cleaner body. It uses suction power and air wind simultaneously when cleaning dust while using the same electric energy Which is superior to the conventional vacuum cleaner and thus has excellent energy efficiency. The suction force of the air wind acting perpendicularly to the floor is relatively reduced when viewed from the suction side, so that the force To facilitate cleaning, and always It has the effect of keeping a single clean power.

In addition, the suction unit and the cleaner body are separated from each other by a hose, a handle, and an extension pipe, thereby driving the cleaner body separately. There is no need to add a control unit. Easy cleaning by using a separate small vacuum cleaner when cleaning a corner, a narrow space, a gap, a bed or a curtain, or by using a direct inhaler instead of a separate suction unit .
