Description

Vacuum cleaner {Vacuum cleaner}

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner configured to be able to easily separate and empty the dust container in a position where the wire is stored in the cord reel after cleaning.

1 and 2 show a configuration of a vacuum cleaner for showing a conventional embodiment. As shown, the vacuum cleaner has a suction force generated by a main body 10 having a suction means for sucking air in the room and a fan f which is rotated by the driving of the motor M included in the main body. It includes a suction nozzle (6) through which the indoor air flows. The main body 10 has a dust container D capable of collecting dust introduced through the suction nozzle 6, and its bottom and side surfaces are supported by the lower body 1, and an upper portion of the dust container D is covered with a lid ( The supporting rod 2 'formed on the upper cover 2 is inserted into and fixed to the insertion portion 4' formed at the center of 4). Therefore, in order to separate or fasten the dust container D from the main body 10, the upper cover 2 must be opened.

And between the main body 10 and the suction nozzle 6, a suction hose 8 made of a flexible material and the operation operation button connected to the end of the suction hose 8 to adjust the suction force of the cleaner The operation part 5 which the 5 'is comprised, and the extension pipe 7 etc. which connect the said operation part 5 and the suction nozzle 6 are provided in order, and the suction force which the said main body 10 generate | occur | produces is mentioned above. It is possible to transfer to the suction nozzle (6). Air, which is sucked through the suction nozzle 6 and contains dust or lint, which is introduced through the suction hose 8, flows into the first suction port 9a formed in the upper part of the dust container D. Foreign substances such as dust or lint, which are included in the air introduced into the first suction opening 9a, flow along the inner wall surface of the outer body C1 of the dust container D while the foreign substances having a large mass are separated from the upper portion of the partition plate S. It is accumulated in the primary dust collecting part (D1) which is a space formed in the.

On the other hand, the air flowing through the inside of the outer body (C1) does not pass through the second inlet (9b) of the dust contained in the air while passing through the plurality of second inlet (9b) formed in the primary filter (f1). Dust that cannot be adhered to the surface of the primary filter f1 or falls to the primary dust collecting part D1. Air introduced into the primary filter f1 through the second suction port 9b flows in a tangential direction from the upper side wall of the inner body C2 through the third suction port 9c. Since the inner body C2 has a shape of a funnel that is gradually axially directed toward the bottom thereof, the air flows into the bottom while the air flowing in the inner body C2 flows in a spiral direction, and the flow force becomes weaker. In this process, the dust contained in the air with weak flow force is separated from the air by centrifugal force and falls to the secondary dust collecting part D2 formed at the bottom of the partition plate S. Part of the dust is separated into the secondary dust collecting part (D2) by its own weight, and the air is separated from the dust container (D) through the discharge port (9d) formed in the center portion.

That is, the dust having a weight moves downward while rotating along the inner wall surface of the inner body C2, and the dust having a relatively light weight is included in the air and flows through the inner central portion of the inner body C2, and then discharges ( Through 9d).

According to the dust container (D) having a dust collecting method by the dual cyclone as described above, there is a disadvantage that the fine dust is very light weight is discharged through the discharge port (9d) of the dust container together with the air. In order to prevent the fine dust from flowing into the fan f or the motor M from the discharge port 9d, the fine dust is filtered by the secondary filter f2 formed in the lid part of the dust container D.

The filtered air in the dust container (D) is discharged to the outside of the main body 10 by the fan (f) generating the suction force by the motor (M) which is the suction means for generating the suction force. At this time, the fine dust not filtered in the dust container (D) is completely filtered by the tertiary filter (f3), it is discharged to the outside of the cleaner while cooling the heat of the motor. This air flow is enabled by the rotational force of the fan f mounted on the motor M.

Through the process as described above, garbage such as dust or lint is collected in the dust container (D). As the amount of garbage collected in the dust container D increases, the function of the primary filter f1 is impaired and the air flow is not smooth. As a result, the motor M is overloaded, which may cause a failure. By frequently emptying the dust box so that such a problem is not caused, smooth air flow can be expected.

However, in order to clean the dust container by the conventional vacuum cleaner structure, the following inconvenience comes. To remove the dust container D from the main body 10 of the vacuum cleaner, press the button of the handle 3 to rotate the upper cover 2 which is fastened to the main body 10 by the hinge 2b. Pull. When the upper cover 2 is opened in the body 10, the upper portion of the dust container (D) is exposed to the outside. The dust container (D) is separated from the main body (10), and the lid (4) covering the upper part of the dust container (D) is removed to remove the garbage collected in the dust container (D), and the primary fastened to the lid (4). The filter (f1) must be removed to clean the dirt from the surface of the primary filter (f1). For the cleaning process of the dust container (D) there is a hassle to open the top cover (2) formed in the main body.

In addition, the configuration is also complicated because it must pass through several filters to filter out fine dust.

It is an object of the present invention to provide a vacuum cleaner which is configured to easily separate and clean a dust container from a main body.

Another object of the present invention is to provide a vacuum cleaner having the convenience of use by efficiently disposing the device constituting the main body.
