Description

  The present invention relates to a vacuum cleaner, and more particularly to a dust collector of a cyclonic vacuum cleaner.

  In recent years, dust collectors for cyclone vacuum cleaners use centrifugal force to separate and separate dust mixed in the air by swirling the air sucked together with dust from the suction tool in the cylindrical dust collector. Dust is collected in a dust collection chamber below the cylindrical dust collection unit, and the air from which the dust has been separated is sucked into the suction side by the electric blower. It is necessary to periodically clean the dust box filter. As shown in FIG. 9, conventionally, when cleaning the primary filter unit 105, the handle 102 is inverted, the buckle 103 is removed, the handle 103 is used as a handle, the cover unit 101 is removed from the dust box unit 106, and then the primary filter unit 105 is removed. The filter unit 107, which is a detachable integrated component composed of the filter unit 105 and the secondary filter unit 104, is taken out from the dust box unit 106. (For example, refer to Patent Document 1).

  FIG. 1 shows an overall perspective view of a vacuum cleaner provided with a dust collector in Embodiment 1 of the present invention.

In FIG. 1, the cleaner body 1 includes a suction tool 2 having an opening (not shown) for sucking dust connected to a suction port 1 a provided below the cleaner body 1. Includes an electric blower 5 for sucking dust and a dust collector 6 for collecting dust. Further, the hose 3 connected to the suction port 1b provided behind the suction port 1a, the connection pipe 4 connected to the tip of the hose, and the suction opening provided at the tip of the connection pipe 4 (see FIG. It is possible to suck in dust and the like adhering to high places such as walls and ceilings.

  FIG. 2 is a perspective view of the dust collector from an oblique front, and FIG. 3 is a perspective view of the dust collector from an oblique rear. 2 and 3, the dust collector 6 is roughly divided into components, and the outer shell is a dust box main body 15, an upper cover 8 configured to close the upper surface of the dust box main body 15, and a handle provided on the upper cover 8. 9 and a bottom pig 17 provided so as to close the lower surface of the dust box main body 15.

  The bottom pig 17 can be rotated by a hinge portion 15a provided in the dust box main body 15, and is locked to the dust box main body 15 by a claw 17a. The dust box main body 15 is airtight (maintained airtight) by the packing C20 attached to the bottom pig 17.

  FIG. 4 is a cross-sectional view taken along the line AA in FIG. As shown in FIG. 4, the bottom pig 17 is configured such that the claw 17 a is opened, unlocked, and can be opened and closed. When the slider 16 is pressed, the claw 17 a is opened and the bottom pig 17 is opened. The upper cover 8 is engaged with the dust box body 15 by the left and right buckles 10 (see FIGS. 2, 3 and 5).

  FIG. 5 is a sectional view taken along line BB in FIG. As shown in FIG. 5, a primary filter 14 is provided in the dust box body 15 in a substantially concentric manner, and has an infinite number of through holes. Below the primary filter 14 is an umbrella-shaped extending portion shape 14a.

  A secondary filter 11 formed in a pleat shape is provided above the primary filter 14, and a dust removing portion 12 for removing dust accumulated in the secondary filter 11 by means such as vibration, A rotating lever 7 is provided as a means for applying vibration to the portion 12.

  The dust-mixed air sucked from the suction tool 2 shown in FIG. 1 is sucked into the suction port B23 provided in the dust box main body 15 shown in FIG. 3 via the suction port 1a provided below the cleaner body 1. . The air sucked into the air inlet B23 flows into the cyclone space 24 formed by the outer periphery of the primary filter 14 and the dust box main body 15 shown in FIG. 5, and dust and fine dust mainly composed of cotton dust are generated by the swirling flow generated there. Centrifugated with the contained air. Dust, mainly cotton dust, is accumulated in the dust accumulation space 26 through the dust collection passage 25 formed between the extending portion 14 a and the dust box body 15.

  In the cyclone space 24, dust is separated into coarse dust and fine dust, and the air containing fine dust passes through the primary filter 14, and the fine dust is filtered by the secondary filter 11. And the air which does not contain fine dust passes the secondary filter 11, passes the inlet port A22 shown in FIG. 3, and is attracted | sucked by the electric blower 5 shown in FIG.

  The fine dust accumulated on the secondary filter 11 is attached to the dust removing unit 12 by rotating (manually) the rotating lever 7 combined with the dust removing unit 12 provided on the inner diameter of the secondary filter 11. The spring 13 is peeled from the secondary filter 11 by bringing the spring 13 into contact with the rib 11a and applying vibration. The peeled fine dust passes through the space inside the primary filter mounting frame 14b, and is accumulated in the inner cylinder 27 provided below the primary filter 14 and inside the extending portion 14a.

The upper part of the inner cylinder 27 has an inclined shape so that the peeled fine dust can be easily guided to the bottom part of the inner cylinder 27. The inner cylinder 27 communicates with the primary filter 14, and the opened lower end is isolated from the dust accumulation space 26 by a packing D 21 provided on the lid 17.

  The diameter of the primary filter mounting frame 14 b is larger than the outer diameter R 1 of the primary filter 14 and larger than the inner diameter R 2 of the outer wall 28 of the dust box body 15 that forms the cyclone space 24. The primary filter mounting frame 14b is inserted from above the dust box main body 15, and is held in pressure contact with the holding rib 15b by packing B19.

  The secondary filter 11 is provided above the primary filter 14, and a packing A 18 is attached to the outer periphery of the secondary filter 11, and the lower side 18 a of the packing A 18 is in pressure contact with the holding rib 14 c of the primary filter 14. The upper side 18b of the holding and packing A is circumferentially tight with the inner wall of the upper cover 8, and each plays the role of air tight. The outer diameter of the secondary filter 11 is larger than the outer diameter R1 of the primary filter 14, and the air flow resistance is reduced as much as possible.

  Next, the detailed structure of the cover part 29 is demonstrated. As shown in FIGS. 5 and 6, a secondary filter 11 having a packing A 18 inserted on the outer periphery is set on an upper cover 8 provided with a handle 9 and left and right buckles 10, and above the dust removing portion 12 and the secondary filter 11. Combined with the rotating lever 7 through the hole and the hole of the upper cover 8, and is connected from the center of the dust removing unit 12 to the center of the rotating lever 7 by fastening means such as a screw. A cover portion 29 is formed. With such a configuration, the secondary filter 11 is sandwiched and held between the rotary lever 7, the upper cover 8, and the dust removing unit 12.

  FIG. 7A is a perspective view showing an assembly configuration of the filter unit 30 of the dust collector 6. As shown in FIG. 7 (a), the filter unit 30 includes a cover unit 29 and a primary filter 14, and the primary filter 14 and the cover unit 29 are a combination of the convex part 11b of the secondary filter and the concave part 14a of the primary filter. The bayonet system is detachable, and in the mounted state, as shown in FIG. 8, the filter unit 30 has an integrated configuration.

  FIG. 7B is a perspective view illustrating an assembly configuration of the filter unit 30 and the dust box body 15 in the dust collector 6. The filter unit 30 is mounted in the dust box main body 15, and the left and right buckles 10 are integrally held by being hooked on the engaging portions provided in the dust box main body 15.

  Further, as shown in FIG. 7B, when the primary filter 14 is cared for, the handle 9 is inverted, the left and right buckles 10 are removed, and the filter unit 30 is taken out of the dust box body 15 using the handle 9 as a handle. Therefore, the primary filter 14 can be easily maintained.

  As described above, the dust collector according to the present invention is a dust collector that collects dust based on the principle of cyclonic separation, and is intended to facilitate the maintenance of the filter. It can be applied to electric vacuum cleaners.
