Description

Vacuum cleaner {Vacuum cleaner}

The present invention relates to a vacuum cleaner that inhales dust or other foreign matter together with air and separates and discharges the foreign matter from the air.

In general, a vacuum cleaner generates suction power by a motor operated by a power source, and uses the same to suck dust from the outside into the cleaning body. At this time, the cleaning main body is provided with a separating means for separating the sucked foreign matter and air.

One known separation means is a filter. The material is made of a material such as paper or nonwoven fabric that selectively passes air without passing foreign substances. Filters need to be replaced or cleaned because of their poor air permeability.

The filtering cloth according to the prior art has a longitudinal shape that protrudes toward the inlet through which dust and air are sucked in. In this way, the sucked dust accumulates from the periphery of the filtering cloth and still prevents the central portion of the filtering cloth from being blocked, thereby preventing the deterioration of suction power for a long time. However, the bell-shaped filtering cloth is sucked toward the motor during the operation of the vacuum cleaner, but rather has a disadvantage of reducing the filtering area. Therefore, there is a problem in that the suction force is lowered due to the clogging of the filtering cloth before the dust collecting bin is full, so that the vacuum cleaner needs to be disassembled and cleaned. In addition, the filtering cloth according to the related art has an approximate longitudinal shape, and thus has a disadvantage in that the area for filtering is excessively dependent on the size of the cross-sectional area of the internal space. That is, in order to increase the filtering area, it is necessary to secure a large cross-sectional area of the inner space, and thus there is a technical problem that the volume of the cleaning main body must be increased.

One technique for separating dust and the like from the air is to physically separate foreign substances by forming a cyclone with air sucked into the cleaner body. In order for the cyclone to form effectively, a cavity of appropriate shape is required inside the cleaning body, and the suction force must be large for effective separation.

As set forth in Patent Document 2 and Patent Document 3 below, large vacuum cleaners used in factories and specialized cleaning companies have good conditions for applying such cyclones. In addition, the large size vacuum cleaner is provided with a separate tray as shown in Patent Literature 1 to facilitate the loading of the main body and to be easily moved.

On the other hand, the driving device that provides the suction force occupies a large part of the weight of the entire vacuum cleaner, which is the main cause of the noise and vibration. In the prior art, as the driving device equipped with a large motor has a structure seated on the upper portion of the cleaner body, there is a disadvantage in that the operation noise is very loud by the interior of the empty cleaner body.

[Patent Document 1] Republic of Korea Patent Publication No. 10-2010-0105115 (2010.09.29) [Patent Document 2] Republic of Korea Patent Publication No. 10-2011-0000254 (2011.01.03) [Patent Document 3] Republic of Korea Patent Publication No. 10-2011-0000248 (2011.01.03)

The present invention has been made to solve the above-mentioned problems, and has the purpose of reducing vibration and noise by reducing the operation noise or vibration of the drive motor is transferred to the cleaner body.

It also has the purpose to improve the filter structure to increase the filtering efficiency. In more detail, the filtering area is increased according to the air flow inside the cleaner.

It also has the purpose of being able to shake off the dust on the filter without disassembling the cleaner.

It also has the purpose of naturally forming the cyclone with the inhaled air.

In addition, it is easy to separate the foreign matter gathered inside the cleaner, and in particular, has the purpose to facilitate the removal of a lot of accumulated foreign matter.

In order to solve the above problems, the present invention provides a cyclone frame mounted on the ground, a filter dust collector mounted on the holder frame and having a filter inside therein, and connected to an open lower end of the filter dust collector and sucked air cyclone. A cyclone dust collector configured to form and discharge foreign substances to the lower portion, and the foreign matter falling from the cyclone dust collector is contained in the collecting container separated from the cyclone dust collector and the filter dust collecting unit, and is mounted to the mounting frame and is located above the filter dust collector. A vacuum cleaner including a drive unit connected to provide suction power is provided.

The horizontal frame extending to the rear of the filter dust collecting portion is coupled to the mounting frame, the driving unit may be fixed to the horizontal frame.

Meanwhile, the filter part is coupled to the inner surface of the housing of the filter dust collecting part and has an outer circumferential surface coupled to the support plate and the through hole in which at least one through hole is formed, and in the air flow direction generated inside the housing by the operation of the driving part. It extends along and may contain an empty filter post.

Furthermore, the filter pillar may be made of a flexible filter cloth through which air can pass.

In an additional configuration, the filter dust collecting part includes a hair part to shake off the filter pillar, wherein the hair part is coupled to the gripping part and the gripping part protruding through the housing of the filter dust collecting part and is connected to the filter pillar. It may include.

On the other hand, the inlet pipe is sucked in the air in the direction in contact with the inner peripheral surface of the cyclone dust collector is mounted, the air passing through the inlet pipe may be introduced into the cyclone dust collector inclined downward.

Furthermore, the mounting frame has a pair of pillars formed to face up and down long holes facing each other, and a pair of extension pieces having one end connected to each of the long holes and a horizontal line connecting the extension pieces. The handle portion is provided with a bar, which is constrained and rotated to the long hole, one end is rotatably coupled to the pillar portion, the other end is rotatably coupled to the extension piece, the end of the extension piece when the horizontal bar is lowered It may include a locking portion coupled to protrude from the opposite side of the link portion and the extension piece to ride in the long hole, the cradle formed in the container is detachably coupled.

In addition, the engaging portion is a cylindrical projection having a mounting groove is formed on the outer circumferential surface, the holder includes a mounting piece fixed to be spaced apart from the outer wall surface of the container, the mounting piece is a horizontal piece that is placed on the mounting groove, the horizontal It may include a stopper piece which is formed concavely from one end to the upper part of the biasing and is formed perpendicularly to the end of the insertion groove and stops the movement of the cylindrical projection.

In addition, the lower portion of the container can be equipped with a rolling member.

According to an embodiment of the present invention, as the driving unit is installed separately from the main body filtering dust, the noise or vibration caused by the driving unit is not directly transmitted to the main body, and thus the operation noise or vibration is reduced.

In addition, as the driving unit is coupled to the rear side of the cleaner, the noise transmitted to an operator mainly located in front of the cleaner may be reduced.

In addition, the filter area can be secured even if the cleaning main body is not made large, so that the filtering effect can be seen. In addition, as the filtering area increases during operation, the effect of removing foreign substances such as dust increases.

In addition, as the hair part is further included, it is possible to shake off the dust caught on the filter pillar without disassembling the vacuum cleaner, thereby eliminating the inconvenience caused by dust scattering.

By forming the inlet pipe of the cyclone filter part inclined, the cyclone is more reliably formed, and the rotational force of the cyclone is increased to effectively separate the foreign matter mixed in the air.

The container can be easily installed or detached only by lifting and lowering the lever without the need for a clamp or a clip, which makes it easy to handle the vacuum cleaner. In addition, the large-capacity vacuum cleaner can remove the container full of foreign matter and then move on the ground in a rolling manner, which increases the convenience of handling.

Hereinafter, with reference to the accompanying drawings will be described the configuration, function and operation of the vacuum cleaner according to the present invention.

1 to 2 show a vacuum cleaner according to an embodiment of the present invention.

Vacuum cleaner 100 according to the present invention includes a mounting frame (1), filter dust collector (2), cyclone dust collector (3), container (4) and the driving unit (5).

Mounting frame (1) is a member that is mounted on the ground is the remaining components, such as filter dust collection unit. The mounting frame may be composed of a frame, and as shown, a cloud 11 such as a caster is mounted on the bottom.

In addition, the front of the mounting frame (1) may be further equipped with a storage box 12 for storing a flexible hose connected to the vacuum cleaner 100, the handle frame 13 is mounted to facilitate the operator to carry and carry. . In FIG. 2, the handle frame 13 is mounted on the front and the rear, respectively. The shape and configuration of such a handle frame may vary as needed.

The vacuum cleaner 100 may be divided into a cleaning main body 100a in which dust is largely collected, and a driving unit 5 providing suction force. Here, the cleaning main body 100a includes a container 4, a cyclone dust collector 3, and a filter dust collector 2 from the ground.

The inner spaces of the container 4, the cyclone dust collector 3, and the filter dust collector 2 are communicated with each other in a direction perpendicular to the ground. Air containing foreign matters is introduced into the cyclone dust collector 3, and the foreign matters and air are first separated by the cyclone. Foreign matter falls and collects in the container (4), and the air that rises in the cyclone passes through the filter dust collecting section (2), the extra foreign matter and air are separated secondarily. The air after the secondary separation is discharged to the atmosphere through the drive unit 5 (see FIG. 3). The heavy particles can be separated quickly by undergoing primary separation by cyclone in the inhaled air. Fine dust, which cannot be separated in the primary separation, is filtered out in the secondary separation of the filter method, thereby increasing the dust separation efficiency. Furthermore, the large volume of particles are filtered out in the primary separation, thereby reducing the problem of clogging the secondary separation filter and achieving a certain level of filtering effect over a long period of time.

Looking at the mounting frame (1) according to an embodiment of the present invention, the bottom frame 15 and the pair of pillars 16 which are erected side by side in the floor frame 15 placed on the ground in Figures 1 and 2 Include. The bottom frame 15 is equipped with a caster, the user can easily move the vacuum cleaner.

The upper end of the pillar portion 16 is mounted to the handle frame 13 is connected to the front. A horizontal frame 14 extending rearward is mounted at the middle height of the pillar. The end of the horizontal frame 14 is connected to the other handle frame (13).

In particular, the horizontal frame 14 is extended toward the rear of the vacuum cleaner (100). The drive unit 5 is mounted to the horizontal frame 14.

The drive unit 5 includes an electric motor, a reduction gear, and the like, and transmits rotational power of the motor to the fan to provide suction power. The configuration and action of the drive unit for exerting a suction force may be the same as the known configuration. The suction port of the driving unit 5 is connected to the pipe of the upper portion of the filter dust collecting unit 2 through the flexible pipe (F). At this time, the steel pipe may be used in place of the flexible pipe.

Although not shown, a filter cartridge may be further provided at the upper end of the filter dust collecting part connected to the flexible pipe. The filter cartridge is composed of a filter of a known configuration, which can filter foreign matter from the air that passes through the inside of the filter dust collecting part and moves to the driving part. The filter cartridge, for example, may be mounted inside the lid detachable from the upper end of the filter dust collecting unit, or may be mounted inside the elbow pipe connecting the flexible pipe and the lid.

In FIG. 2, the driving part 5 is mounted inside the case of the cube. In the case, an exhaust hole 511 for discharging air is opened toward the cleaning main body (filter collecting part in FIG. 2). The air discharged from the drive unit 5 is discharged into the space between the cleaning base 100a and the drive unit 5 (see FIG. 3). In the illustrated embodiment, as the driving unit 5 is positioned above the mounting frame 1, the driving unit 5 is positioned at the height of the face or upper body of the worker. In the present invention, the air discharged from the driving unit 5 does not directly touch the worker around the vacuum cleaner, but first touches the cleaning main body 100a and is dispersed into the surrounding atmosphere. Therefore, the air discharged from the driving unit directly comes into contact with the worker during the cleaning operation, so that there is no discomfort.

In addition, the horizontal frame 14 extends to the rear of the filter dust collecting unit 2, and as the driving unit 5 is coupled to the horizontal frame 14, the driving unit 5 is located at the rear side of the cleaning base 100a. Specifically, in FIG. 1, the driving unit 5 is located behind the filter dust collecting unit 2, and the driving unit 5 is covered by the filter dust collecting unit 2 when viewed from the front. The worker cleans while pulling the suction hose drawn out from the vacuum cleaner. As the driving unit is located at the rear of the cleaning main body, the noise generated by the driving unit is hidden by the cleaning main body and is not immediately transmitted to the worker. Therefore, the worker can clean in a quieter environment.

The cyclone dust collector is a cylinder member connected to the open lower end of the filter dust collector. 2 to 4, the cyclone dust collector 3 is detachably coupled to the lower end of the filter dust collector 2 using a clamp. However, unlike shown, the cyclone dust collector may be fixed by screw coupling with the filter dust collector or may be fixed to the filter dust collector.

On the other hand, the inner space in which the cyclone is formed is formed in the cyclone dust collector 3. This inner space has the shape of an inverted truncated cone. The inner space is formed in a circular cross section, and the inner diameter decreases gradually toward the bottom.

The inner space of the cyclone dust collector 3 is equipped with a guide 32 which decreases in diameter downward. The upper end of the guide 32 is coupled between the filter dust collecting part 2 and the cyclone dust collecting part 3, or is coupled to the support plate 61 of the filter part 6 which is caught under the cyclone dust collecting part 3. Between the inner surface of the cyclone dust collecting part 3 and the outer surface of the guide 32 is formed a space in which the introduced air descends while turning. The center of the guide 32 is opened up and down so that the upward flow formed in the center of the cyclone 3 can move toward the filter dust collecting part 2.

The upper and lower ends of the cyclone dust collector 3 are open. Accordingly, the upper end is in communication with the filter dust collecting part (2), the lower end is in communication with the container (4).

An inflow pipe 31 is formed in the cyclone dust collector 3. As shown in FIG. 4, the inflow pipe 31 is connected in a direction in contact with the inner circumferential surface of the cyclone dust collector 3. Therefore, the introduced air is swiveled along the circular inner circumferential surface (see the direction of the arrow in FIG. 4) to easily generate the cyclone.

In addition, as shown in FIG. 3, the inlet pipe 31 is formed to be inclined with respect to the ground, so that the air passing through the inlet pipe 31 is inclined downward and flows into the cyclone dust collector 3. In this way, as the air is injected obliquely downward, generation of a swirl flow (cyclone) downward in the cyclone dust collector is made easier, and a powerful swing force can be obtained. As a result, foreign matter sucked in the air is more effectively separated from the cyclone dust collector.

The foreign matter separated from the cyclone dust collector 3 falls by its own weight. Dropped foreign matter is collected inside the container (4). The container 4 forms a sealed storage space in the lower portion of the cyclone dust collector 3 so that the flow of air does not occur significantly even during the formation of the cyclone. Therefore, the foreign matter collected in the drop is not mixed with the cyclone and rises despite the frequent operation of the driving unit.

2 to 3 and 5 to 6 illustrate a filter dust collector and a filter unit mounted thereto.

The upward flow generated in the inner space of the cyclone dust collector 3 flows from the lower portion to the upper portion of the filter dust collector 2, and then moves to the driving unit 5. The filter unit 6 filters foreign matters such as dust from the air flowing from the bottom up in this way.

The filter part 6 is coupled to the inner surface of the housing of the filter dust collecting part 2 and has a support plate 61 having at least one through hole 611 formed therein and a filter column 62 coupled to each through hole 611. Include.

The support plate 61 is a circular or polygonal plate material corresponding to the inner cross section of the filter dust collecting part 2. In the figure, the support plate 61 is formed of a disc corresponding to the cross-sectional shape of the cylindrical housing of the filter dust collecting part 2. Although not specifically illustrated, a stepped portion may be formed at the lower end of the housing of the filter dust collecting part, and the support plate may be caught therein.

The filter column 62 is made of a material through which air passes and filters out foreign substances such as dust contained in the air. Such a material may be a filter cloth having pores such as paper, nonwoven fabric, and hemp. The filter cloth also has the flexibility to bend or flex gently.

Although not necessarily so, each filter column 62 has a cylindrical shape corresponding to the through hole 611. Although not shown as an example, in order to increase the total area of the filter pillar, the cross-sectional area may be increased toward the top.

The lower end of the filter post 62 is open and the upper end is blocked. The rising air passes through the circumference or the top of the inside of the filter column 62 and moves out of the filter column 62. The filter column 62 is erected inside the filter dust collecting unit 2 as the rising air flows.

Referring to Figure 6, the state passing through the filter pillar 62 by the rise of air is shown by the arrow. Air passing through the through hole of the support plate 61 passes through the inner circumferential surface and the upper surface of the filter column 62.

At this time, as the filter pillar 62 is made of a filter cloth through which air can pass, foreign matter is filtered on the inner circumferential surface and the upper surface of the filter pillar 62. Therefore, if the length of the upper and lower lengths of the filter columns 62 is sufficiently long, the area in which the foreign matter is filtered can be largely secured. Compared with the use of a single filtering cloth in the prior art, since the side of each filter pillar can be used, there is an advantage that the filterable area is largely secured.

In addition, the extending direction of the filter column 62 substantially coincides with the flow direction of air. therefore

When the air is sucked in from the upper end of the inner space, the side of the filter pillar 62 is inflated toward the outside of the filter pillar 62. In FIG. 5, the filter column 62 when the vacuum cleaner is not operated is indicated by a dotted line. The side of the filter pillar 62 is inflated during operation, thereby increasing the filtering area. Therefore, compared to the conventional technology in which the filtering cloth is attached to protrude toward the inlet of the dust and foreign matter in the prior art, and thus the filtering area is reduced during operation, the present invention increases the filtering area during operation, so that clogging of the filtering member by the foreign matter is prevented. It is reduced.

On the other hand, the shape, number, and arrangement pattern of the through holes 611 formed in the support plate 61 can be changed. For example, although not shown, at least one through hole may be formed only in the central portion of the support plate, leaving a predetermined width from the circular edge of the support plate so that the cyclone is stably formed at the cyclone dust collecting portion below the support plate. In this case, the initial cyclone is easily generated as the air rotates through the inner circumferential surface of the cyclone dust collector, and the upstream generated strongly in the center of the cyclone is induced to rise through the through hole, thereby separating the primary by the cyclone and the filter part. Secondary separation is achieved efficiently.

Although not necessarily necessary, the filter dust collecting part 2 includes a hair part 63 to shake off the filter pillar 62. Hair portion 63 is to physically shake off the foreign matter caught on the inner surface of the filter pillar 62 without removing the cleaning base.

5, the hair part 63 is shown. The hair part 63 includes a grip part 631 protruding through the housing of the filter dust collecting part 2 and a hair frame 632 coupled to the grip part 631 and connected to the filter pillar 62. .

The gripping portion 631 is a bar that penetrates through the housing of the filter dust collecting part 2 and protrudes to the outside. A soft packing 636 for sealing the inside of the housing is coupled between the housing and the grip portion 631. The grip part 631 penetrates through the housing loosely so that a user can hold and shake. The shape of the gripping portion can vary otherwise.

A hair frame 632 is coupled to the gripping portion 631 extending into the housing of the filter dust collector 2. In the figure, the hair frame 632 is a frame woven in a substantially disk shape. However, the hair frame can be changed to other types of structures as long as it does not resist the flow of air. The upper portion of the filter pillar 62 is connected to the hair frame 632. Accordingly, when the grab portion 631 protruding to the outside of the filter dust collecting part 2 is grabbed and shaken, the filter pillar 62 is shaken together with the hair frame 632, and thus the foreign matter caught on the inner circumferential surface of the filter pillar is shaken off.

In a further optional configuration, the hair frame 632 is provided with at least one hair rod 633 extending between the filter pillars. The hair bar 633 may include a vertical bar 634 in the vertical direction and a horizontal bar 635 connected between the vertical bars and positioned in a space between the filter pillars. The hair rod 633 can physically strike the filter pillar 62 to more effectively shake off the foreign matter stuck to the inner circumferential surface of the filter pillar.

Foreign materials falling from the filter column fall from the through-hole of the support plate and flow down the inclined inner peripheral surface of the cyclone dust collector to be loaded into the container. This makes it possible to separate foreign substances adhering to the inner circumferential surface of the filter pillar without disassembling the cleaning main body.

2 and 7 to 10 are views related to the configuration for detachably coupling the container in the cyclone dust collecting unit.

The container 4 is in contact with the cover plate 33 in the upper portion opened to the cylindrical member. The cover plate 33 is formed with a hole 331 connected to the open lower end of the cyclone dust collector 3. The upper edge of the cover 4 is in contact with the bottom circumference of the cover plate 33. At this time, a sealing member (not shown) for airtightness of the container 4 and the cover plate 33 is interposed around the lower end of the cover plate in contact with the top of the container 4. At this time, the sealing member may be coupled to the upper end of the container (4). The sealing member has an elastic force and is capable of compressive deformation. For example, the sealing member may be made of rubber.

The cover plate 33 is coupled to the lower portion of the cyclone dust collector. Thus, even if the container 4 is removed to the bottom, the cover plate is still attached to the cyclone dust collector.

The container 4 is coupled with a rolling member 41 such as a caster. Cloud member 41 is provided with a plurality of radially on the outside of the container (4). When the container 4 is separated from the cyclone dust collecting part 3, the rolling movement is possible on the ground through the rolling means 11. On the other hand, when the container 4 comes into contact with the cyclone dust collector 3, the cloud member also falls from the ground as it rises from the ground.

The height of the container 4 is lower than the bottom of the cyclone dust collector (specifically, a cover plate connected to the bottom of the cyclone dust collector). When the height of the container is fixed by lifting the container through the coupling means provided in the holding frame 1 and the container, the cyclone dust collecting part 3 and the container 4 are in contact with each other without any gap.

Such coupling means includes a handle portion 7, a link portion 8, a locking portion 9, and a holder 43 provided on the outer circumferential surface of the container 4 provided in the pillar portion.

First, the cradle 43 is formed on both sides of the container (4). The position of the cradle 43 corresponds to the column 16. Cradle 43 may be a plate-shaped member coupled to the upper side of the outer surface of the container (4).

Meanwhile, the handle portion 7 includes a horizontal bar 71 and a pair of extension pieces 72 extending side by side at both ends of the horizontal bar. The spacing of the extension piece 72 is substantially the same as the spacing of the inner surface of the pillar portion 16. The handle portion 7 is a member for the operator to hold the horizontal bar 71 to act as a means for operating the coupling means.

Horizontal bar 71 has the shape of a rod, it may be formed in a gentle bend to be easy to grab. In addition, the extension piece 72 is formed so that the planes face each other. Such a handle portion may be formed by properly bending one rod body, and both end portions of the handle portion may be compressed to form surfaces parallel to each other.

Each extension piece 72 is coupled to the elevating and restrained by the long hole 161 formed to face each other inside the pillar portion 16. The extension piece 72 is also free to rotate in the long hole 161. To this end, the connection of the extension piece 72 and the long hole 161 may be used a general coupling member such as bolts, washers, nuts. In addition, although not shown, a bearing may be used to reduce wear of a portion moving or rotating in a long hole.

On the other hand, the link portion 8 is one end 81 is rotatably coupled to the pillar portion 16, the other end 82 is rotatably coupled to the extension piece 72, horizontal bar 71 The lower end of the extension piece 72 is to be raised by riding the long hole (161).

Specifically, one end 81 of the link portion 8 is hinged to the through-hole 162 formed in the vertical lower direction of the long hole 161. In addition, the other end 82 of the link portion 8 is hinged to the extension piece 72. At this time, the other end 82 of the link portion 8 is hinged at the middle portion closer to the horizontal bar 71 than the end position of the extension piece 72 coupled with the long hole 161. At this time, the hinge coupling of both ends of the link portion is made through a bolt, nut, washer, bearing, and the like as described above.

As a result, when the horizontal bar 71 descends, the end of the extension piece 72 rides through the long hole 161, and conversely, when the horizontal bar 71 rises, the end of the extension piece 72 rides through the long hole 161. Will descend.

On the other hand, the locking portion 9 is a member protruding from the opposite side of the extension piece 72, the holder 43 formed in the container 4 is detachably coupled. For example, the engaging portion may be formed of a protrusion projecting to face each other inside each end of the extension piece coupled to the long hole. In addition, the cradle is formed with a recessed upper portion corresponding to the projection. Alternatively, a protrusion may be provided on the holder, and a concave groove may be formed at the end of the extension piece.

Looking specifically at the relationship between the locking portion and the cradle, the locking portion 9 may be a cylindrical projection 91 is formed on the outer circumferential surface and the rotatable groove 911 is rotatably coupled at the end of the extension piece (72). have. In addition, while the cradle 43 includes a cradle 431 fixed to be spaced apart from the outer wall surface of the container 4, the cradle 431 has a lower portion of the horizontal piece 432, the insertion groove ( 433), the stopper piece 434 can be formed in order.

Since the cylindrical projection 91 is movable up and down in a state in which the extension piece 72 is restrained by the long hole 161, the cylindrical protrusion 91 is movable only in the vertical direction as described above. When the container placed on the ground is pushed between the pillars, the horizontal piece 432 moves through the mounting groove 911 of the cylindrical protrusion 91.

Thereafter, when the container 4 is pushed further, since the mounting groove 911 of the cylindrical protrusion 91 is caught by the stopper piece 434 formed vertically, the container can no longer enter.

Subsequently, when the horizontal bar 71 is lowered by manipulating the handle part 7, the cylindrical protrusion 91 is lifted up and gripped by the insertion groove 433. In addition, the additional increase of the cylindrical protrusion 91 will lift the container 4 upwards. That is, as the cylindrical projection 91 is inserted into the insertion groove 433, the collecting container 4 can be in close contact with the connecting cylinder without being separated between the pillars.

Cradle 43 is made of a bracket including a cradle 431, both sides are fixed to the container, the cradle 431 is spaced apart from the outer wall of the container (4). At this time, a portion of the cylindrical projection 91 is inserted into the space between the mounting piece 431 and the outer wall of the container 4.

Hereinafter, the operation relationship of the coupling means will be described with reference to FIGS. 9 to 10.

Figure 9 (a) is a state in which the handle portion is lifted, the container can be separated from the vacuum cleaner to the outside (see Fig. 10 (a)). As the horizontal bar is lifted based on the drawing, the link part 8 is rotated to the right side, and the end of the extension piece 72 is descended to the maximum by riding the long hole 161. As a result, since the cylindrical projection 91 is lowered below the insertion groove, the container can be taken out of the vacuum cleaner.

On the other hand, Figure 9 (b) is a state in which the handle portion 7 is lowered, the container is raised and in close contact with the connecting cylinder (see (c) of Figure 10). Based on the drawings, as the horizontal bar is lowered, the link portion 8 is rotated counterclockwise with respect to the rotation axis of the end 81. Accordingly, the end of the extension piece 72 is raised to the upper portion of the long hole 161, and as a result, the cylindrical projection 91 provided at the end of the extension piece 72 is raised in the insertion groove to raise the container.

At this time, the horizontal bar is further lowered, the rotary shaft formed at the other end 82 of the link portion 8 passes through the virtual connecting line (L) formed by the long axis 161 and the rotary shaft of one end of the link portion (8). Specifically, the rotation axis center A to which the link portion 8 and the extension piece 72 are connected includes the hinge axis center B, the link portion 8, and the pillar part of the end of the long hole 161 and the extension piece 72. It is positioned further to the left through the virtual connecting line L connecting the hinge axis center C of (16).

Thus, when the load of the container 4 acts vertically downward on the end of the extension piece 72, the load of the container 4 forces the link portion 8 biased to the left to be rotated further counterclockwise. Accordingly, the extension piece 72 is forced to rotate clockwise with its end coupled to the long hole 161 as the axis of rotation. As a result, the load of the container is transmitted to the link portion and the extension, and finally the raised position of the container is fixed while being rotated to an angle where the handle part can no longer rotate.

At this time, in order to limit the rotation angle of the handle portion can be configured to be caught on the bottom portion. Alternatively, a protruding structure may be formed in the column part to limit the rotation angle of the handle part.

The present invention is provided by a pair of dust collectors separated up and down, each of the dust collector is capable of different filtering processing, and has the advantage that can significantly reduce the foreign matter contained in the final discharged air. In addition, as a pair of dust collectors are mounted on one mounting frame, the cleaning operation of frequently moving the position may be facilitated.

In addition, when the heavy container should be emptied during cleaning, it can be easily removed or mounted by raising or lowering the container in accordance with the principle of leverage, thereby greatly improving the convenience of the operator.
