Description

Electric Cleaner {ELECTRIC CLEANER}

The present invention relates to an electric vacuum cleaner having a cyclone dust collector.

A conventional vacuum cleaner is disclosed in Japanese Patent No. 3990419. The vacuum cleaner is provided with a dust collector that can be attached and detached from a main body unit in which an electric blower is incorporated. The dust collector is horizontally provided with a cylindrical dust collecting container in which swirling air flow is formed, and a filter such as a pleat filter for collecting dust is provided downstream of the dust collecting container.

The filter is held by the frame, and is rotatably supported by placing the axial direction horizontally in a storage case having a circular cross section. The wiper (cleaning member) which slides on the end surface of the storage case in the axial direction is provided. The storage case is provided with a vibration damping unit for tapping and damping the filter when the filter is rotated.

In addition, an opening is formed in the upper portion of the end surface of the storage case in communication with the peripheral surface of the dust collecting container. The opening portion is covered by a lid portion pushed in one direction, and the lid portion is configured to open the opening portion in response to the pressing force by the contact of the wiper.

In the vacuum cleaner having the above-described configuration, when the electric blower is driven, dust on the surface to be cleaned is sucked, and the air flow containing the dust flows into the dust collecting container to form a swirling air flow in the dust collecting container. At this time, the wiper retracts from the lid portion and the opening is closed. The dust contained in the air stream is separated by centrifugal force and stored in the dust collecting container. The air stream from which dust was removed flows out from the dust collection container, and fine dust is collected by the filter. And the airflow from which the dust was removed is exhausted through an electric blower.

When the electric blower is stopped and the filter is rotated by a predetermined operation, dust falls from the filter to the bottom of the storage case by tapping the vibration damper. The wiper, which rotates integrally with the filter, scrapes the dust off the bottom of the storage case and leads it to the opening. When the wiper stops rotating at the position where the wiper is in contact with the lid portion, the opening is opened, and the dust scraped up by the wiper falls into the dust collecting container through the opening. Thereby, the dust which removed the filter can be collect | recovered in the dust collection container.

However, according to the conventional vacuum cleaner, since the airflow flows back when the opening is opened at the time of cleaning, it is necessary to retract the wiper from the lid to close the opening. In addition, at the time of dust removal of a filter, it is necessary to arrange a wiper in the position which contacts a lid part, and to open an opening part. For this reason, it is necessary to control the rotational position of the wiper, and there is a problem that the structure of the vacuum cleaner becomes complicated.

An object of the present invention is to provide an electric vacuum cleaner capable of recovering dust during dust removal of a filter with a simple structure.

In order to achieve the above object, the present invention provides an electric vacuum cleaner in which a cyclone dust collector is installed in a main body portion in which an electric blower is incorporated.

The dust collector,

A cylindrical dust collecting container in which the swirling airflow is formed,

An inner passage arranged at a central portion of the dust collecting container and guiding the airflow flowing out of the dust collecting container upward;

A shielding portion covering an upper surface of the dust collecting container on an outer circumferential side of the inner cylinder and having an opening formed therein;

A filter disposed above the shield and collecting dust;

A vibration damping part for removing dust from the upper surface of the shielding part by removing the filter;

A wiper for sliding the upper surface of the shield by a predetermined operation to guide dust into the opening;

And a cover portion which pivots on the lower surface of the shield and closes the opening by suction when the electric blower is driven, and opens the opening by its own weight when the electric blower stops.

According to this configuration, when the cleaning is performed by the vacuum cleaner, the air flow including the dust flows into the dust collecting container of the dust collecting device whose upper surface is blocked by the shielding portion, and the swirling air flow is formed in the dust collecting container. At this time, the cover part pivoted on the lower surface of the shielding part by the suction force of the vacuum cleaner closes the opening. The relatively large dust contained in the swirling airflow in the dust collecting container is separated and separated by centrifugal force. The airflow flowing out of the dust collecting vessel is led to the upper filter through the inner cylinder. The filter collects fine dust, and the airflow from which the dust has been removed is exhausted out of the main body. When the electric blower stops, the cover portion opens the opening portion by its own weight. When the filter is damped by the vibration isolator, dust falls on the upper surface of the shield from the filter. When the wiper is slid to the upper surface of the shielding part by a predetermined operation, dust on the upper surface of the shielding part falls into the dust collecting container through the opening. As a result, the filter can be removed to recover dust from the dust collecting container.

The present invention is also characterized in that in the vacuum cleaner of the above configuration, the inlet is disposed at the front of the dust collector and the opening is disposed at the rear of the dust collector. According to this configuration, the inlet and the lid are spaced apart in the circumferential direction, and the opening of the lid is prevented by the airflow flowing into the dust collecting container from the inlet.

In addition, the present invention is characterized in that, in the vacuum cleaner of the above configuration, the cover portion is pivoted at the front end portion to the shielding portion. According to this structure, a pivot axis | shaft is arrange | positioned at the inner peripheral side with respect to an open end part, and can form a big opening part in the shield part which is circular in plan view. In addition, when the main body is placed upright so that the front part is disposed upward, the lid part is placed downward with the pivot shaft disposed upward. As a result, the cover part closes the opening to prevent leakage of dust from the dust collecting container.

The present invention is also characterized in that, in the vacuum cleaner having the above-described configuration, the dust collector is disposed to be inclined so that the rear portion of the shielding portion is lowered to the main body portion. According to this structure, the dust on the upper surface of the shielding part slides to the opening part of the rear part, and dust can be collect | recovered more efficiently.

Moreover, in the vacuum cleaner of the said structure, the annular protrusion part is provided in the upper surface inner edge of the said shield part, and the said wiper slides to the outer peripheral side of the said protrusion part, It is characterized by the above-mentioned. According to this configuration, the wiper is slid to the outer circumferential side of the protruding portion, thereby preventing the dust from falling into the inner cylinder of the dust guided to the opening. Thereby, the dust which fell to the inner cylinder is prevented from guide | inducing to a filter at the time of the drive of an electric blower.

According to the present invention, the cover portion pivoted on the lower surface of the shielding part closes the opening by suction when the electric blower is driven, and opens the opening by self weight when the electric blower is stopped. It can prevent and collect dust by dust removal of a filter.

The wiper 36 is provided with a flexible member 36a, such as synthetic rubber, at the lower end thereof, and is provided as a shield 52 (see FIG. 3) of the inner cylinder portion 50 described later by the rotation of the vibration damping member 31. To slide. The engaging portion 36b protrudes and is installed on the lower surface of the inner circumferential side of the wiper 36.

5 and 6 show an exploded perspective view and a top view of the inner cylinder part 50. 3, 5 and 6, the inner cylinder part 50 has the inner cylinder 51 arrange | positioned coaxially in the center of the dust collection container 22, and extends to the outer peripheral side at the upper end of the inner cylinder 51, and the dust collection container ( A shield 52 that covers the upper surface of 22 is provided. The inner cylinder 51 is provided with the airflow outlet 51a in the circumferential surface. As for the shielding part 52, the annular annular part 52c which forms the passage of airflow is provided in the peripheral part of the upper surface 52a. The airflow flowing out of the dust collecting container 22 through the outlet 51a raises the inner cylinder 51 and is guided to the filter 37 through the annular portion 52c.

The upper surface 52a of the shielding part 52 is formed in the inclined surface which consists of the conical surface which an inner peripheral side goes down, and the dust fell by the damping of the filter 37 is deposited. At an inner circumferential portion of the upper surface 52a of the shield 52, an annular protrusion 52e is formed to protrude upward. The opening part 52d is opened in the rear part of the shielding part 52 to the outer peripheral side of the projection part 52e.

The opening part 52d is opened and closed by the cover part 53 pivoted to the disc part 52b which forms the lower surface of the shielding part 52. The pivot shaft 53a of the cover portion 53 is provided at the front end of the cover portion 53. Thereby, the cover part 53 can arrange | position the pivot shaft 53a to the inner peripheral side with respect to an open edge part, and can form the big opening part 52d in the shield part 52 which is circular in plan view. The packing 53b is provided in the peripheral part of the lid part 53 by insert molding, etc., and prevents airflow leakage when the opening part 52d is closed. Packing may be provided at the periphery of the opening 52d.

The wiper 36 is disposed inside the annular portion 52c, and the flexible member 36a slides on the upper surface 52a of the shield 52 by rotation. Thereby, the dust which fell to the upper surface 52a of the shielding part 52 can be guide | induced to the opening part 52d. At this time, the wiper 36 can slide to the outer circumferential side of the protrusion 52e to prevent the dust from falling into the inner cylinder 51.

The shaft portion 55b of the compression portion 55 is fitted to the inner cylinder 51. A spiral flange portion 55a protruding in the radial direction is provided below the compression portion 55. Compression unit 55, the coupling portion (not shown) provided on the upper end of the shaft portion 55b is coupled to the coupling portion 36b of the wiper 36 to rotate integrally with the wiper 36. The dust deposited on the lower part of the dust collecting container 22 by the rotation of the compression part 55 is compressed by the conveyance action of the flange part 55a.

In the vacuum cleaner 1 of the said structure, the dust of the to-be-cleaned surface is sucked in from the suction port 5 by the drive of the electric blower 6, and the extension pipe 4 and the connection hose 3 are distributed. The airflow containing the dust flows into the dust collecting container 22 from the inlet 21 and forms a swirling airflow in the dust collecting container 22. At this time, the lid part 53 closes the opening part 52d of the shield part 52 by suction of the electric blower 6. The relatively large dust contained in the airflow is removed by the centrifugal force of the swinging airflow, and is deposited at the bottom of the dust collecting container 22.

The airflow from which the large dust was removed flows out from the outlet 51a into the inner cylinder 51, and the fine dust is collected by the filter 37. The airflow passing through the filter 37 flows out of the dust collector 20 through the dust collector exhaust port 24. The airflow flowing out from the dust collector 20 flows through the duct 15 and is exhausted from the exhaust port 7 through the electric blower 6.

When the electric blower 6 is stopped by the operation of the operation unit 14, the vibration suppression motor 33 of the vibration suppression device 30 is driven only for a predetermined time. At this time, as shown in FIG. 7, the cover 53 has its open end draped downward from the pivot shaft 53a by its own weight, thereby opening the opening 52d of the shield 52. As shown in FIG. The vibration damping body 31 rotates through the gear 32 by the drive of the damping motor 33. At this time, the connection of the handle 41 and the damping rotating body 31 by the clutch unit 42 is released to prevent the rotation of the handle 41.

The vibration damping part 38 hits the filter 37 by the rotation of the damping rotating body 31, and the dust collected by the filter 37 is damped and falls to the upper surface 52a of the shielding part 52. At this time, the dust on the upper surface 52a of the shielding portion 52 is guided to the opening portion 52d by the wiper 36 to be collected in the dust collecting container 22.

In addition, the coupling part 36b of the wiper 36 engages with the compression part 55 by the rotation of the damping rotating body 31, and the compression part 55 rotates. By rotation of the compression part 55, the flange part 55a compresses the dust of the bottom part of the dust collection container 22. As shown in FIG.

When the dust collecting apparatus 20 is removed from the dust collecting chamber 19 and the handle 41 is rotated, the damping rotating body 31 is rotated through the clutch portion 42 to filter the filter 37. And the dust which fell to the upper surface 52a of the shielding part 52 is collect | recovered by the wiper 36 to the dust collecting container 22 through the opening part 52d.

According to this embodiment, the lid part 53 pivoted on the lower surface of the shielding part 52 closes the opening part 52d by suction at the time of the drive of the electric blower 6, and at the time of the stop of the electric blower 6; Since the opening portion 52d is opened by its own weight, the airflow leakage during cleaning can be prevented with a simple structure, and dust from dust removal of the filter 37 can be recovered.

Further, since the inlet 21 is disposed in the front part of the dust collector 20 and the opening portion 52d is disposed in the rear part of the dust collector 20, the inlet 21 and the lid portion 53 are in the circumferential direction. Spaced apart. Thereby, opening of the cover part 53 by the airflow which flows into the dust collection container 22 from the inflow port 21 can be prevented. Therefore, airflow leakage at the time of cleaning can be prevented reliably.

Moreover, since the cover part 53 arrange | positioned at the rear part of the dust collector 20 is pivoted to the shielding part 52 in the front end part, the pivot part 53a is arrange | positioned to the inner peripheral side with respect to the open part with the cover part 53 arrange | positioned. do. Thereby, the big opening part 52d can be formed in the shield part 52 which is circular in plan view. Moreover, when the main body part 2 is installed upright so that the front part may be arrange | positioned upwards, the cover part 53 arrange | positions the pivot shaft 53a to upper side and falls down. Thereby, the lid part 53 can close the opening part 52d, and can prevent the outflow of dust from the dust collection container 22. FIG.

Moreover, since the dust collector 20 is arrange | positioned in the main-body part 2 so that the rear part of the shield part 52 may descend, the dust of the upper surface 52a of the shield part 52 will slide to the opening part 52d of the rear part. The dust can be collected more efficiently.

Moreover, since the annular protrusion part 52e is provided in the inner edge of the upper surface 52a of the shielding part 52, and the wiper 36 slides to the outer peripheral side of the protrusion part 52e, the dust guide | induced to the opening part 52d Fall to the inner cylinder 51 is prevented. Thereby, the dust which fell to the inner cylinder 51 is prevented from being guide | induced to the filter 37 again at the time of the drive of the electric blower 6, and can collect | recover the dust to the dust collection container 22 reliably.
