Definitions
- the present invention relates to a vacuum cleaner. More particularly, the present invention relates to a cyclone-type vacuum cleaner that separates dust from drawn-in air using a cyclone dust collector.
- vacuum cleaners draw in dirt and dust-laden air by a suction force created by a fan or blower within the vacuum cleaner body.
- Most prior art vacuum cleaners separate and collect dirt and dust using a filtration bag that is commonly known as a dust bag. As the dust bag fills, the vacuum cleaner effectiveness decreases, necessitating frequent emptying or replacement of the dust bag. When replacing or emptying a dust bag, however, the user is required to handle the contaminated dust bag, which is unpleasant and unsanitary for the user.
- cyclone dust collectors In order to avoid the problems with prior art vacuum cleaner dust bags, cyclone dust collectors were developed and their use has become widespread. As is known, cyclone dust collectors provide high cleaning efficiency and semi-permanent use by simply removing a dust-collection bin and emptying its contents.
- FIG. 1 illustrates a prior art cyclone dust collector in cross section, and its attachment or mounting to the main body of a vacuum cleaner.
- the cyclone dust collector comprises a cyclone body 10 for separating the dust from the drawn-in air, a dust receptacle 20 for collecting the dust separated from the cyclone body 10 , and a connection member 30 for connecting and separating the dust receptacle 20 with respect to the cyclone body 10 .
- the cyclone body 10 has a drawn-in air flow path or “drawing path” (not shown in FIG. 1 for clarity) at one side thereof, which is in fluid communication with a suction brush (not shown). Dust-laden air is drawn into the cyclone body 10 through the drawn-in air path from a surface being cleaned.
- the drawn-in air path is preferably configured so that the dust-laden air is drawn in tangentially with respect to the cyclone body 10 side walls to assist in the creation of a cyclonic air flow inside the cyclone body 10 .
- the air drawn in through the drawing path flows along an inner wall of the cyclone body 10 and thereby forms a whirling air current that separates dust and dirt by the centrifugal force exerted on suspended particles as they rotate in the cyclone body 10 .
- the cyclone body 10 has an air discharge path 12 in fluid communication with the vacuum generator (not shown). After centrifugally separating dust and dirt from the drawn-in air in the cyclone body 10 , the filtered air is discharged to the outside of a vacuum cleaner body 1 through the air discharge path 12 and the vacuum generator. Dust and dirt separated from the drawn-in air in the cyclone body 10 is collected in the dust receptacle 20 connected to a lower part of the cyclone body 10 .
- the dust receptacle 20 fills with dust and dirt, vacuum cleaner efficiency deteriorates. In order to maintain the vacuum cleaner's efficiency, the dust receptacle 20 needs to be emptied. In order to empty the dust receptacle 20 , the connection member 30 disposed below the dust receptacle 20 is first pivoted or rotated to allow the dust receptacle 20 to be separated from the cyclone body 10 . Once the dust receptacle 20 is separated from the cyclone body, 10 , a user can withdraw the dust receptacle 20 from the cleaner body 1 and dispose of the contents of the dust receptacle 20 .
- the dust receptacle 20 To remount the dust receptacle 20 to the cleaner body 1 after it's emptied, the dust receptacle 20 is re-assembled to the connection member 30 and the connection member 30 is pivoted in the opposite direction. Therefore, the dust receptacle 20 can be connected to the lower part of the cyclone body 10 .
- a problem with the foregoing structure is that the dust receptacle 20 is separated by moving it vertically from the cyclone body 10 . Therefore, space is needed for the vertical movement of the dust receptacle 20 to allow its removal and installation.
- the need to allow the dust receptacle to move vertically increases the needed size of the vacuum cleaner.
- a cyclone body 10 having a dirt filtration or separation grill much more vertical space is required to move the dust receptacle 20 , such that the dust receptacle 20 is not obstructed by the grill part during separation thereof. Accordingly, the installation space of the cyclone dust collector is increased. To make a vacuum cleaner that uses the prior art cyclone body 10 small yet having a reasonable dust collection capacity requires compromise between size and dust capacity.
- some canister-type vacuum cleaners have a structure in which a dust receptacle can be mounted or separated without a vertical movement.
- the filtration grill should not protrude from the cyclone body in order to prevent obstruction by the grill part during separation of the dust receptacle. Therefore, the dust receptacle is compactly sized.
- a cyclone vacuum cleaner comprising a cleaner body; a dust receptacle removably mounted within the cleaner body; and a cyclone body that is hingedly attached to an upper part of the cleaner body and which can pivot about an axis of the hinge that attaches the cyclone body to the cleaner body.
- the cyclone body can be selectively connected to and disconnected from, i.e., “separated” from the dust receptacle by rotation of the cyclone body about the pivot or axis of the hinge.
- the cyclone body When the cyclone body is connected to the dust receptacle, it can be disconnected from the receptacle by rotating it about the aforementioned axis by as little as 5° to as many as 90° depending on the geometry of the cleaner body.
- the cyclone vacuum cleaner of the present invention since the cyclone body is hinged upon the cleaner body and opened upward, the dust receptacle can be heightened without being obstructed by the grill part. As a result, dust collecting capacity can be increased compared to a conventional art, without enlarging the size of the vacuum cleaner.

Abstract
A cyclone vacuum cleaner provides an improved capacity dust receptacle by structuring the cyclone body of the vacuum cleaner to be pivotally mounted to the vacuum cleaner body. The cyclone body is disconnected from the dust receptacle by rotating or “turning up” the cyclone body by rotating it about the pivotal mount. A dust receptacle removably mounted in the cleaner body and a cyclone body hinged on an upper part of the cleaner body are selectively separated and connected with respect to the dust receptacle.
Description
- This application claims benefit under 35 U.S.C. § 119(a) of Korean Patent Application No. 2004-93413, filed Nov. 16, 2004, the entire contents of which are incorporated herein by reference.
- The present invention relates to a vacuum cleaner. More particularly, the present invention relates to a cyclone-type vacuum cleaner that separates dust from drawn-in air using a cyclone dust collector.
- It's well known that vacuum cleaners draw in dirt and dust-laden air by a suction force created by a fan or blower within the vacuum cleaner body. Most prior art vacuum cleaners separate and collect dirt and dust using a filtration bag that is commonly known as a dust bag. As the dust bag fills, the vacuum cleaner effectiveness decreases, necessitating frequent emptying or replacement of the dust bag. When replacing or emptying a dust bag, however, the user is required to handle the contaminated dust bag, which is unpleasant and unsanitary for the user.
- In order to avoid the problems with prior art vacuum cleaner dust bags, cyclone dust collectors were developed and their use has become widespread. As is known, cyclone dust collectors provide high cleaning efficiency and semi-permanent use by simply removing a dust-collection bin and emptying its contents.
-
FIG. 1 illustrates a prior art cyclone dust collector in cross section, and its attachment or mounting to the main body of a vacuum cleaner. As can be seen inFIG. 1 , the cyclone dust collector comprises acyclone body 10 for separating the dust from the drawn-in air, adust receptacle 20 for collecting the dust separated from thecyclone body 10, and aconnection member 30 for connecting and separating thedust receptacle 20 with respect to thecyclone body 10. - As is known, the
cyclone body 10 has a drawn-in air flow path or “drawing path” (not shown inFIG. 1 for clarity) at one side thereof, which is in fluid communication with a suction brush (not shown). Dust-laden air is drawn into thecyclone body 10 through the drawn-in air path from a surface being cleaned. The drawn-in air path is preferably configured so that the dust-laden air is drawn in tangentially with respect to thecyclone body 10 side walls to assist in the creation of a cyclonic air flow inside thecyclone body 10. The air drawn in through the drawing path flows along an inner wall of thecyclone body 10 and thereby forms a whirling air current that separates dust and dirt by the centrifugal force exerted on suspended particles as they rotate in thecyclone body 10. - The
cyclone body 10 has anair discharge path 12 in fluid communication with the vacuum generator (not shown). After centrifugally separating dust and dirt from the drawn-in air in thecyclone body 10, the filtered air is discharged to the outside of avacuum cleaner body 1 through theair discharge path 12 and the vacuum generator. Dust and dirt separated from the drawn-in air in thecyclone body 10 is collected in thedust receptacle 20 connected to a lower part of thecyclone body 10. - As the
dust receptacle 20 fills with dust and dirt, vacuum cleaner efficiency deteriorates. In order to maintain the vacuum cleaner's efficiency, thedust receptacle 20 needs to be emptied. In order to empty thedust receptacle 20, theconnection member 30 disposed below thedust receptacle 20 is first pivoted or rotated to allow thedust receptacle 20 to be separated from thecyclone body 10. Once thedust receptacle 20 is separated from the cyclone body, 10, a user can withdraw thedust receptacle 20 from thecleaner body 1 and dispose of the contents of thedust receptacle 20. - To remount the
dust receptacle 20 to thecleaner body 1 after it's emptied, thedust receptacle 20 is re-assembled to theconnection member 30 and theconnection member 30 is pivoted in the opposite direction. Therefore, thedust receptacle 20 can be connected to the lower part of thecyclone body 10. - A problem with the foregoing structure is that the
dust receptacle 20 is separated by moving it vertically from thecyclone body 10. Therefore, space is needed for the vertical movement of thedust receptacle 20 to allow its removal and installation. The need to allow the dust receptacle to move vertically increases the needed size of the vacuum cleaner. In case of acyclone body 10 having a dirt filtration or separation grill much more vertical space is required to move thedust receptacle 20, such that thedust receptacle 20 is not obstructed by the grill part during separation thereof. Accordingly, the installation space of the cyclone dust collector is increased. To make a vacuum cleaner that uses the priorart cyclone body 10 small yet having a reasonable dust collection capacity requires compromise between size and dust capacity. - Although they are not shown, some canister-type vacuum cleaners have a structure in which a dust receptacle can be mounted or separated without a vertical movement. However, in such a case, the filtration grill should not protrude from the cyclone body in order to prevent obstruction by the grill part during separation of the dust receptacle. Therefore, the dust receptacle is compactly sized.
- In prior art cyclone
dust collector bodies 10, when thedust receptacle 20 capacity is small, thedust receptacle 20 needs to be emptied frequently. It is therefore preferable that thedust receptacle 20 have as large a capacity as possible. However, to increase volume of thedust receptacle 20, the whole size of thecleaner body 1 needs to be increased accordingly. A cyclonic vacuum cleaner that provides increased dust collector capacity but which also reduces overall vacuum cleaner size would be an improvement over the prior art. - There is provided a cyclone vacuum cleaner comprising a cleaner body; a dust receptacle removably mounted within the cleaner body; and a cyclone body that is hingedly attached to an upper part of the cleaner body and which can pivot about an axis of the hinge that attaches the cyclone body to the cleaner body. The cyclone body can be selectively connected to and disconnected from, i.e., “separated” from the dust receptacle by rotation of the cyclone body about the pivot or axis of the hinge. When the cyclone body is connected to the dust receptacle, it can be disconnected from the receptacle by rotating it about the aforementioned axis by as little as 5° to as many as 90° depending on the geometry of the cleaner body.
- According to the cyclone vacuum cleaner of the present invention, since the cyclone body is hinged upon the cleaner body and opened upward, the dust receptacle can be heightened without being obstructed by the grill part. As a result, dust collecting capacity can be increased compared to a conventional art, without enlarging the size of the vacuum cleaner.
- The above aspect and other features of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawing figures, wherein;

The matters defined in the description such as a detailed construction and elements are examples to assist in understanding of the invention. Well-known functions or constructions are not described in detail since they would tend to obscure the invention in unnecessary detail.

FIG. 2 illustrates the concept of a cyclone dust collector of a cyclone vacuum cleaner according to an embodiment of the present invention. Since the structure of a vacuum cleaner body of a vacuum cleaner is well known to those of ordinary skill in the art and not germane to the invention disclosed and claimed herein, the structure of a vacuum cleaner body is mostly omitted from the figures for clarity and additional description of a vacuum cleaner is omitted for brevity. - In the structure shown in
FIG. 2 , adust receptacle 102 is removably mounted to acyclone body 101, which is in turn, mounted to a vacuum cleaner body (not shown) via a pivot point or hinge 103 that is located away from thecyclone body 101 by a predetermined spacing L. By rotating the cyclone body 101 (clockwise as shown) about the pivot point or hinge 103, thedust receptacle 102 can be attached to and separated from thecyclone body 101. - Those of ordinary skill in the art will appreciate that as shown in the figures, for a given angle θ, as measured between the plane of the
cyclone body top 106 and horizontal 107, thecyclone body 101 is “lifted” above thedust receptable 102 by rotating thecyclone body 101 about the axis of the hinge that couples thecyclone body 101 to the vacuum cleaner body. Thevertical distance 104 that thecyclone body 101 rises or can be “lifted” above thedust receptacle 102 is approximated by the trigonometric expression, L×(sin θ). Thus it can be seen from this expression that for a given rotation angle θ, increasing the distance L by which thecyclone body 101 is away from thepivot point 103, increases thevertical rise 104 or “lift” of thecyclone body 101 above thedust receptacle 102 to provide easy mounting and separation of thedust receptacle 102 from thecyclone body 101. - As described above, since the
cyclone body 101 pivots on thehinge 103 mounted to the cleaner body, thedust receptacle 102 is not obstructed by agrill part 105 protruded from the center of thecyclone body 101 during mounting and separation of thedust receptacle 102 to and away from thecyclone body 101. Accordingly, thedust receptacle 102 can be made larger than would otherwise be possible using prior art structures shown inFIG. 1 . -
FIG. 3 shows a cyclone dust collector as mounted to a cleaner body according to a first embodiment of the present invention. In this figure, acyclone dust collector 100 is mounted to a receiving portion in thecleaner body 1 and a vacuum generator (not shown) is disposed at one side of thecyclone dust collector 100. Thecyclone dust collector 100 comprises acyclone body 110 for separating dust from drawn-in air, and adust receptacle 120 for collecting the dust separated by thecyclone body 110. - The
cyclone body 110 is attached to apartition 2 of thecleaner body 1 by a two-part hinge 113. Thepartition 2 constitutes the receiving portion of thecleaner body 1. - As can be seen, the
cyclone body 110 is attached to (or in an alternate embodiment comprises) afirst part 111 of thehinge 113 that is located (or formed) at one side of thecyclone body 110. A secondhinge supporting part 112 of thehinge 113 is attached to (or in an alternate embodiment comprises) part of thepartition 2 of thecleaner body 1. Thefirst hinge part 111 and thehinge supporting part 112 are positioned so that thedust receptacle 120 does not obstruct an outer periphery of thecyclone body 110 and thegrill part 115 formed in thecyclone body 110 when thedust receptacle 120 is separated by rotating thecyclone body 110 about the axis of thehinge 113 by a predetermined angle. More specifically, thefirst hinge part 111 and thehinge supporting part 112 are sized, located and arranged so that thecyclone body 110 can be rotated about the axis of thehinge 113 by approximately 5˜90° with respect to the plane in which top opening of thedust receptacle 120 lies. The rotation angle of thecyclone 110 is determined according to the structures of thecleaner body 1 mounting thecyclone dust collector 100 and of thedust receptacle 120. - Although it's not shown in
FIG. 3 , thecyclone body 110 comprises a drawn-in air path in fluid communication with a suction brush of a vacuum cleaner that runs over or contacts a surface to be cleaned. An air discharge path is in fluid communication with the vacuum generator. Therefore, dust-laden air drawn in by the suction brush from a surface to be cleaned, is guided into thecyclone body 110 through the drawn-in air path. The air, from which the dust is centrifuged in thecyclone body 10, is discharged to the outside of thecleaner body 1 through the discharging path and the vacuum generator. Since the structure of thecyclone body 110 for drawing in the dust-laden air, separating the dust and discharging the cleaned air is not the essential matter of the present invention, detailed description thereof will be omitted hereinafter. - The
dust receptacle 120 is connected to a lower part of thecyclone body 110 so as to collect the dust separated from the dust-laden air through thecyclone body 110. Thedust receptacle 120 is removably mounted to the receiving portion of thecleaner body 1 below thecyclone body 110. When thecyclone body 110 is turned up, i.e., rotated clockwise about thehinge 113 axis, an upper part of thedust receptacle 120 is separated from thecyclone body 110. Also, by turning down thecyclone body 110, i.e., rotating counter-clockwise, the upper part of thedust receptacle 120 can be easily re-connected to the lower part of thecyclone body 110. - At a
lower support stand 3 of the receiving portion of thecleaner body 1, to which thedust receptacle 120 is mounted, a mountingguide part 130 may be provided to guide the mounting and separation of thedust receptacle 102 and stabilize a position of thedust receptacle 120. - By configuring the
cyclone body 110 to be fixed to thecleaner body 1 and pivotable around an axis so that it's rotation about the axis causes the cyclone body to rise, as shown inFIG. 4 , a total height of thedust receptacle 120 can be lengthened by a distance ‘h’ compared to that which is possible using the prior art cyclone dust collector shown inFIG. 1 . Accordingly, capacity of thedust receptacle 120 can be increased. - For
FIG. 5 shows a second embodiment of the invention, which provides even greatercapacity dust receptacle 120′ and which enables thedust receptacle 120′ to be detached from thecyclone body 110′ at smaller inclination angles of thecyclone body 110′ around the axis of thehinge 113. InFIG. 5 , thetop opening 127 of thedust receptacle 120′ and thebottom opening 117 of thecyclone body 110′ are canted or inclined with respect to each other as shown. Thebottom opening 117 of thecyclone body 110′ of thedust collector 100′ is inclined at an angle that matches the inclination of thetop opening 127 of thedust receptacle 120′ - A distinctive feature of the second embodiment shown in
FIG. 5 is that thecyclone body 110′ comprises a sloping bottom opening 117 the pitch or inclination of which matches the pitch or inclination of theopening 127 of the dust receptacle 120.′ - The top opening, which is also referred to herein as a first
sloping part 127, is slanted “upward” in the direction away from thecleaner body 1. Thedust receptacle 120′ can thereby be separated from thevacuum cleaner body 1 for emptying by moving it horizontally to the “left” as shown, away from thevacuum cleaner body 1 in the direction of ‘A’ inFIG. 5 . - As is also shown, the sloping bottom opening 117 formed at the lower edge of the
cyclone body 110′ has a corresponding slope that matches the firstsloping part 127, such that thecyclone body 110′ and thedust receptacle 120′ can be in tight contact with each other. A sloping angle of the firstsloping part 127 is determined so that a highest portion of thedust receptacle 120′ (the left side of the firstsloping part 127 with respect toFIG. 5 ) is not obstructed by thecyclone body 110′, and especially by thegrill part 115 formed in the center of thecyclone body 110′. - Removing the
dust receptacle 120′ and replacing it is simple. When thedust receptacle 120′ is filled with dust and needs to be emptied, a user lifts thecyclone body 110′ upward, pivoting thecyclone body 110′ by way of thehinge 113 by a predetermined angle, as shown inFIG. 6 . When thecyclone body 110′ is turned or rotated upwardly, thedust receptacle 120′ is not obstructed by thecyclone body 110′. Therefore, the user is able to empty thedust receptacle 120′ simply by sliding thedust receptacle 120′ sideways or horizontally, in the direction shown by the arrow shown inFIG. 7 . - After emptying the
dust receptacle 120′, the user re-mounts thedust receptacle 120′ to the receiving portion of thecleaner body 1 by simply sliding the dust receptacle toward the right and into the position shown inFIG. 6 . A mountingguide part 130 formed at thelower partition 3 of thecleaner body 1 where thedust receptacle 120′ helps to align thedust receptacle 120′ directly beneath thecyclone body 110′ when thecyclone body 110′ is pivoted downwardly. When the user lowers or turns down thecyclone body 110′, after thedust receptacle 120′ is replaced, the secondsloping part 117 of thecyclone body 110′ is engaged with the firstsloping part 127 of thedust receptacle 120′, as shown inFIG. 5 , thereby enabling reuse of the vacuum cleaner. -
FIG. 8 shows a third embodiment of a cyclone dust collector mounted in a cleaner body of a cyclone vacuum cleaner. With reference toFIG. 8 , acyclone dust collector 100″ comprises acyclone body 110″ and adust collector 120″. As shown inFIG. 8 , thecyclone body 110″ is mounted to the receiving portion of thecleaner body 1 to separate dust from drawn-in air. Adust receptacle 120″ below thecyclone body 110 collects separated dust. - As can be seen in
FIGS. 8 and 9 , thecyclone body 110″ is mounted to a hingedcover 5. The hingedcover 5, being hingedly attached to thecleaner body 1 by ahinge 113″, allows it to pivot or “lift” upwardly by an amount that is proportional to the angle to which the cover is rotated. Therefore, by opening thecover 5 with respect to thecleaner body 1, as shown inFIG. 9 , thecyclone body 110″ is separated from thedust receptacle 120″. By closing thecover 5, thecyclone body 110″ is connected to thedust receptacle 120″, as shown inFIG. 8 . - The
dust receptacle 120″ is connected to a lower part of thecyclone body 110″ and removably mounted in the receiving portion of thecleaner body 1 below thecyclone body 110″. As thecover 5 is opened up, an upper part of thedust receptacle 120″ is separated from thecyclone body 110″. As thecover 5 is closed, the upper part of thedust receptacle 120″ is connected to the lower end of thecyclone body 110″. - On the
lower partition 3 of the receiving portion of thecleaner body 1, where thedust receptacle 120″ is mounted, the mountingguide part 130 fixes the position of thedust receptacle 120″ as it's slid out of and back into thelower partition 3. -
FIG. 10 shows a canister-type vacuum cleaner employing the cyclone dust collector according to the third embodiment of the present invention. When performing cleaning work, a suction force generated by thevacuum generator 7 draws dust-laden air is drawn into thecyclone body 110″ through a suction brush (not shown) fluidly connected with asuction pipe 9. The dust-laden air, being drawn into thecyclone body 110″, forms a whirling air current and separates out the dust that is included in the air. The separated dust drops to thedust receptacle 120″ connected to a lower part of thecyclone body 110″. The air from which the dust is separated through thecyclone body 110″ is discharged out of thecleaner body 1 through thevacuum generator 7. - When the
dust receptacle 120″ becomes full of the dust through the above processes, thedust receptacle 120″ should be separated from thecleaner body 1 to be emptied. - For this, the user opens the
cover 5 of thecleaner body 1, thereby separating thecyclone body 110″ from thedust receptacle 120″. In this state, the user can withdraw thedust receptacle 120″ from thecleaner body 1, remove the dust collected in thedust receptacle 120″ and remount thedust receptacle 120″ to thecleaner body 1. Then, by closing thecover 5, thecyclone body 110″ is connected with thedust receptacle 120″, as shown inFIG. 8 , and therefore, the user can perform the cleaning work again. In other words, the user can connect and separate thecyclone body 110″ with respect to thedust receptacle 120″ simply by opening and closing thecover 5. -
FIG. 11 schematically shows a multi-cyclone dust separator as a fourth embodiment of the present invention, as mounted in a vacuum cleaner. Except for the employment of themulti-cyclone dust collector 200, the other structures, such as hinge-connection between acyclone body 210 and thecleaner body 1 through ahinge 211 and mounting and separation structure of adust receptacle 220, are the same as those of the previous embodiments. Therefore, this embodiment will not be described in detail. - While the invention has been shown and described with reference to certain embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
