DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner having a cyclone type dust collector for separating dust by swirling intake air.

[0002]

2. Description of the Related Art A conventional vacuum cleaner having a cyclone type dust collecting portion is disclosed in Japanese Patent Publication No. 6-85753. FIG. 9 is a perspective view showing the vacuum cleaner. An electric blower (not shown) is provided inside the main body 101, and a suction port (not shown) is formed facing the floor. Main body 10
A cyclone dust collecting unit 103 is supported on the upper part of the first unit 1 so as to be rotatable in the front-rear direction.

FIG. 10 is a front sectional view of the cyclone dust collecting section 103. FIG. 11 is a sectional view taken along the line DD of FIG. According to these figures, the cyclone dust collecting unit 103 has an intake pipe 104 and an exhaust pipe 105 integrally formed outside a cylindrical outer cyclone 113. Outside cyclone 11
Reference numeral 3 denotes a transparent dust collecting portion 113b attached to the upper inflow portion 113c to be integrated. The inflow portion 113c is provided with an inflow port 113a into which intake air flows from the intake pipe 104 substantially in a tangential direction.

[0004] A pipe 106 is arranged between the intake pipe 104 and the exhaust pipe 105. A holding portion 107 (see FIG. 1) to be held by a user is attached to the pipe 106. The operation of the grip 107 causes the wheels 111
(See FIG. 1) so that the vacuum cleaner 100 can be smoothly moved by rotating on the floor surface.

[0005] Inside the outer cyclone 113, a conical inner cyclone 114 is arranged so that the lower part becomes thinner. The lower end of the inner cyclone 114 is open and communicates with a dust container 109 formed integrally with the outer cyclone 113. At the upper end of the inner cyclone 114, an exhaust unit 110 having an annular passage is provided.

The communication passage 10 is provided outside the inner cyclone 114.
8 are formed. The outer cyclone 113 and the inner cyclone 114 communicate with each other through the communication path 108 and the exhaust part 110. In the center of the exhaust part 110, an exhaust pipe 105 is provided.
Is formed with an exhaust port 110a communicating with the exhaust port 110a.

In the electric vacuum cleaner 100 having such a configuration, when the electric blower is driven, a suction force is generated at the suction port. The intake air flowing from the suction port through the intake pipe 104 into the outer cyclone 113 in the direction shown by the arrow A1 through the inlet 113a travels downward while rotating along the inner peripheral wall of the outer cyclone 113 by centrifugal force. . At this time, the intake air collides with the inner surface of the outer cyclone 113, and separates the large dust 112a and deposits it in the outer cyclone 113.

Thereafter, the intake air rises along the outer circumference of the inner cyclone 114, flows into the communication passage 108 in the direction indicated by arrow A2, and flows into the inner cyclone 114 via the exhaust part 110 in the direction indicated by arrow A3. The intake air flowing into the inner cyclone 114 advances downward while turning along the inner peripheral wall of the inner cyclone 114 by centrifugal force. At this time, the intake air collides with the inner surface of the inner cyclone 114, and separates the fine dust 112b and deposits it in the dust collection container 109.

The intake air from which dust and the like have been removed rises in the center of the inner cyclone 114 and is discharged from the exhaust port 110a to the outside of the cyclone dust collector 103 in the direction shown by arrow A4. After that, the air reaches the electric blower through the exhaust pipe 105 and is exhausted to the outside of the vacuum cleaner 100. Thereby, dust collection is performed.

Further, the dust collecting portion 11 integrated with the dust collecting container 109 is provided.
3b is pulled downward and forward, so that the inflow portion 113c
Connection between the inner cyclone 114 and the dust collection container 109 and the outer cyclone 113 are disconnected.
And dust 11 a and dust 11 accumulated in the dust collection container 109.
2b can be discarded.

[0011]

However, in the above-mentioned conventional cyclone type vacuum cleaner, dust may flow out from the exhaust port 110a because the dust is separated by centrifugal force. For this reason, there has been a problem that dust enters the electric blower and causes a failure of the electric blower, and there is a problem that dust is released into the room and harms the environment.

On the other hand, Japanese Patent Application Laid-Open No. 61-179125 discloses
Japanese Patent Application Publication No. JP-A-2005-115125 discloses a vacuum cleaner in which a filter is provided on the suction side of an electric blower to capture dust that could not be collected by a dust bag. Therefore, a cyclone-type vacuum cleaner in which a filter is provided on the suction side of the electric blower to further capture dust that has flowed out of the cyclone dust collecting unit, similarly to this vacuum cleaner, can be considered.

However, if a filter is arranged on the suction side of the electric blower, the filter is clogged, and the main body 101 needs to be disassembled for cleaning, which causes a problem that maintenance is troublesome.

The exhaust pipe 44 has a cylindrical shape.
An exhaust port 44a that communicates the inside and outside of the inside is provided on the peripheral surface. The exhaust port 44a is formed in a mesh shape. The lower end of the exhaust tube 44 is closed by a shielding member 46 which is detachably attached by a screw portion 46d. The shielding member 46 includes a substantially circular portion 46a and a rib 46b formed below the circular portion 46a.

A projecting portion 46c projecting downward is formed on the periphery of the circular portion 46a. Projecting portion 46c and dust collecting chamber 4
A predetermined amount of gap is provided between the first inner wall and the inner wall. The rib 46b is formed radially from the center of the circular portion 46a toward the outer periphery, and has a cross-sectional shape in the present embodiment.

On the inner wall of the dust collecting chamber 41, a rib 41b is projected from the inner peripheral surface toward the center of the dust collecting chamber 41. The dust collecting chamber 41 is fixed to the cover 47 by screws (not shown). The cover 47 has the same external design as the main body 1, and the grip portion 47 a and the main body 1 are provided with locking means 48 for locking the cover 47 in a detachable manner.

The locking means 48 is a spring 48a which locks the lock 4

FIGS. 6 and 7 are a perspective view of the second dust collector 7 as viewed from the front and a perspective view as viewed from the back, respectively. The second dust collector 7 has a case 71 in which a filter 72 made of paper, a nonwoven fabric, a porous body, or the like is disposed. The front surface of the case 71 is shielded by a front panel 71a, and the back surface is opened to form an outflow port 7b.

The upper surface of the case 71 is formed with an inflow port 7a through which intake air flows. Packings 74 and 75 made of an elastic material such as rubber are arranged around the inlet 7a and on the back surface of the front panel 71a. A plurality of ribs 71d are formed on the inner wall of the case 71 to position the filter 72, and to attach the filter 72 to the front panel 71a.
And a space 71h is formed between them.

As shown in FIG. 5, when the second dust collecting body 7 is mounted in the second storage chamber 16, the inflow port 7a is arranged at a position facing the connection suction port 19, and the packing 74 is connected to the connection suction port 19.
Adhere around. A front panel 71a covers the front surface of the second storage room 16 opened toward the first storage room 15, and a packing 7 is provided on the inner wall of the first storage room 15 around the opening.
5 adheres. Thereby, the first and second storage chambers 15, 1
6 is isolated and the intake air passing through the connecting pipe 8 is guided to the second dust collector 7 without leakage. The filter 72 is in close contact with the guard 21 so that the intake air flows out of the outlet 7b to the main body exhaust port 20.

The front panel 71a is provided with a rib 71c projecting therefrom so as to abut on the first dust collector 4. Therefore, by mounting the first dust collector 4, the second dust collector 7
Is held so that no positional deviation occurs. The front panel 71a has a holding portion 7 with two concave portions 71g.
1f is formed. By inserting a finger into the concave portion 71g and gripping the grip portion 71f, the second dust collecting body 7 is
It can be easily detached from the storage room 16.

Further, since the holding portion 71f is formed by the concave portion 71g, it is possible to form the holding portion 71f which needs to be deep enough to be held by a finger without protruding into the first storage chamber 15. For this reason, the inner wall of the first
The main body 1 (FIG. 1) can be provided close to the dust collector 4.
) Can be prevented from increasing.

On the upper part of the front panel 71a, a letter "UP" indicating the direction is formed. At the lower end of the case 71, a rib 71e is formed. Therefore, the user can mount the second dust collecting body 7 in a predetermined direction by the letters “UP”. A symbol such as an arrow may be formed instead of the character “UP”.

In the case where the vertical direction of the second dust collector 7 is erroneously mounted, if the rib 71e is set in the second storage chamber 1
6 cannot be attached to the rib 16a. As a result, the second dust collector 7 protrudes into the first storage chamber 15 and the first dust collector 4 cannot be mounted. Therefore,
The second dust collector 7 is always mounted in a predetermined direction, and the intake air passing through the connecting pipe 8 is reliably guided to the second dust collector 7 and exhausted to the exhaust pipe 18.

Below the first storage chamber 15, a lever 31 whose one end 31a protrudes into the first storage chamber 15 is rotatably disposed about a support portion 31b. The other end of the lever 31 is urged downward, and the connecting member 33 is rotatably connected. Below the second storage chamber 16, a lever 32 whose one end 32 a protrudes into the second storage chamber 16 is rotatably disposed about a support portion 32 b as a fulcrum. A connecting member 33 is rotatably connected to the other end of the lever 32.

When the second dust collector 7 is detached, the L
A character-shaped tip portion 31 a protrudes into the first storage chamber 15. Therefore, even if an attempt is made to mount the first dust collecting body 4, the first dust collecting body 4 cannot be mounted in contact with the distal end portion 31a. The second dust collector 7 is
When mounted in the storage chamber 16, the distal end portion 32a of the lever 32 comes into contact with the rib 71e of the second dust collector 7, and the lever 32 rotates clockwise against the urging force. Thereby, the lever 3
1 rotates counterclockwise, the tip 31a retracts, and the first
The dust collector 4 can be mounted. Therefore, the second
It is possible to prevent the user from forgetting to attach the dust collector 7 and performing a cleaning operation.

The upright-type vacuum cleaner 1 having the above configuration.
0, when the electric blower 2 is driven, the suction port 3
The air flow containing dust flows into the dust collecting chamber 41 of the first dust collecting body 4 from the inlet 41a through the suction pipe 6 and the main body inlet 5 through the suction port 3a. The air flow flows in along the inner wall of the dust collecting chamber 41 and turns inside the dust collecting chamber 41.

Due to the centrifugal force of the airflow swirling in the dust collecting chamber 41, the dust is pushed toward the outer periphery, that is, toward the inner wall of the dust collecting chamber 41. Large dust and the like that cannot pass through the gap between the protruding portion 46c and the inner wall of the dust collection chamber 41 are separated into circular portions 4
6a. Since the swirling flow flowing from the inflow port 41a has a high flow velocity, the swirling flow turns outside the exhaust pipe 44. As a result, the airflow containing dust is not directly exhausted, and clogging of the exhaust port 44a is suppressed.

The swirling flow flows below the circular portion 46a through a gap between the projecting portion 46c and the inner wall of the dust collecting chamber 41. Then, the dust collides with the inner wall of the dust collection chamber 41 and the rib 46b, and the dust is separated. Further, the swirling flow swirling on the outer periphery than the rib 46a is applied to the rib 41 provided on the inner wall of the dust collecting chamber 41.
b, the dust is separated and the dust is prevented from turning. As a result, dust is deposited on the bottom of the dust collection chamber 41.

Further, the swirling flow that descends while reducing the flow velocity due to the collision with the rib 46b reaches the bottom surface of the dust collection chamber 41 and rises substantially in the center of the dust collection chamber 41. At this time, the airflow may include dust accumulated on the bottom of the dust collection chamber 41 again, but the dust collides with the circular portion 46a due to the ascent and is removed.

Thereafter, the light travels in the outer peripheral direction along the lower surface of the circular portion 46a, and collides with the protrusion 46c to travel downward. This prevents dust from entering above the circular portion 46a. Then, the air from which dust has been removed through the outside of the protruding portion 46c is supplied to the exhaust port 44 of the exhaust pipe 44.
is discharged from a.

The discharged intake air flows into the second dust collector 7 through the exhaust part 42a, the connection exhaust port 9, the connection pipe 8, the connection intake port 19, and the inflow port 7a. The first dust collector 4 is provided in the intake.
And dust that has not been captured by the second dust collecting body 7 flows into the lower part of the second dust collecting body 7 and collides with the lower surface of the case 71 to separate the dust. Further, dust that has not been separated is captured by the filter 72, and the cleaned intake air is supplied to the electric blower 2 via the main body exhaust port 20 and the exhaust pipe 18.
It is led to.

Thus, the cyclone type first dust collector 4
As a result, fine dust that is not captured is reliably captured, and the cleaned intake air is exhausted through the electric blower 2. Therefore, the surrounding environment is not harmed, and the intrusion of dust into the electric blower 2 can be prevented, thereby preventing a failure.

When discarding the dust accumulated in the dust collecting chamber 41 of the first dust collecting body 4, the lock 48b is pressed down against the urging force of the spring 48a to release the engagement with the lock receiver 1a. . Then, the first dust collecting body 4 is detached from the main body 1 by grasping the grasping portion 47a. Thereafter, the first dust collecting body 4 is moved to a disposal place, and the dust is discarded by holding the handle 42c of the exhaust part 42a and removing the lid 42 integrated with the exhaust pipe 44 and the shielding member 46.

Thus, dust in the dust collection chamber 41 can be easily discarded. When the first dust collecting body 4 is carried, most of the upper part of the dust collecting chamber 41 is closed by the lid 42, so that the accumulated dust is not released to the outside, and the hygiene of the surrounding environment and the fingers of the user can be reduced. Harm can be suppressed. In addition, the lid 42, the exhaust pipe 44, and the shielding member 46 can be separately formed, and cleaning by brush cleaning or water washing can be easily performed.

When the dust accumulated on the case 71 of the second dust collector 7 is discarded, the user holds the holding portion 71f to detach and attach the second dust collector 7, remove the filter 72, and discard the dust. Clean the filter 72. When the dust disposal and cleaning is completed, the packing 75 of the second dust collector 7
The second dust collecting body 7 is mounted by being pushed into the second storage room 16 until it comes into contact with the inner wall of the storage room 15. As a result, the packing 74 comes into close contact with the periphery of the connection inlet 19.

Then, the exhaust pipe 44, the shielding member 46 and the lid 42 of the first dust collecting body 4 are assembled integrally, and the concave portion 42b and the convex portion 41c are engaged with each other, and the lid 42 is attached to the dust collecting chamber 41. Thereby, the lid 42 is attached to the dust collecting chamber 41 by the seal 43.
Is closed, and the direction of the exhaust part 42a is fixed.

When the first dust collector 4 is mounted in the first storage chamber 15, the lock element 48b of the lock means 48 engages with the lock receiver 1a of the main body 1 by the urging force of the spring 48a, and the first dust collector 4b is engaged. 4 is held in the main body 1. The inlet 41a of the dust collection chamber 41 is in close contact with the main body inlet 5 through the seal 5a, and the end face of the exhaust part 42a is in close contact with the connection exhaust port 9 through the seal 7a to form an intake path. .

According to the present embodiment, the second dust collector 7 is
By arranging in the second storage room 16 which is continuous with the storage room 15, the second dust collecting body 7 can be easily attached and detached through the first storage room 15. Therefore, maintenance such as dust disposal and cleaning work can be easily performed.

Incidentally, after the first and second dust collecting bodies 4 and 7 are integrated by screws or the like, they may be stored in the first and second storage chambers 15 and 16. Further, the dust collecting container 41 of the first dust collecting body 4 and the case 71 of the second dust collecting body 7 may be formed by integral molding. By doing so, the dust can be detached and attached at the same time as the disposal and cleaning of the dust, and the maintainability can be further improved.

Next, FIG. 8 is a sectional view showing the first and second dust collecting bodies 4 and 7 of the vacuum cleaner according to the second embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 7 are denoted by the same reference numerals. The difference from the first embodiment is that the first and second dust collecting bodies 4 and 7 are replaced with the levers 31 and 32.
This is the point that the detection switches 35 and 36 for detecting attachment / detachment are provided. Other configurations are the same as those of the first embodiment.

The detection switches 35 and 36 are disposed below the first and second storage chambers 15 and 16, respectively.

Further, according to the present invention, since the electric blower is operated upon detecting the attachment of the first dust collector or the second dust collector, cleaning is performed by forgetting to attach the first and second dust collectors. Work can be prevented.

Further, according to the present invention, the intake air flows in from above the second dust collector and flows out from the rear surface, so that the intake air flowing from above collides with the lower surface of the second dust collector to separate the dust. . Then, the dust that has not been separated is captured by the filter. Thereby, dust can be efficiently captured and the intake air can be cleaned.

Further, according to the present invention, the second dust collecting body can be gripped by the concave portion provided on the outer peripheral surface of the second dust collecting body, so that the second dust collecting body can be easily removed from the second storage chamber. Can be detached. In addition, a gripping portion that needs to be deep enough to be gripped by fingers does not protrude into the first storage chamber, and the inner wall of the first storage chamber can be provided close to the first dust collector, so that the depth of the main body increases. Can be prevented.

Further, according to the present invention, since the first and second dust collecting bodies are integrated, they can be attached and detached at the same time when dust is discarded and when the dust is cleaned, so that the maintainability can be further improved.
