Description
- This application claims priority under 35 U.S.C §119(a) from Korean Patent Application No. 10-2006-0061069 filed Jun. 30, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
- 1. Field of the Invention
- The present disclosure relates to a vacuum cleaner for cleaning a surface, and more particularly, to a vacuum cleaner having a lifting/lowering unit for use in mounting a dirt collection bin on a cleaner body or removing the dirt collection bin from the cleaner body.
- 2. Description of the Related Art
- Generally, a vacuum cleaner is an appliance for suctioning dust-contained in air, removing dust from the air, and discharging dust-free air, wherein such a vacuum cleaner comprises a cleaner body and a dust collection device mounted in a mounting space formed on the cleaner body. The dust collection device comprises a dust collection bin for temporarily storing filtered dust, wherein in order to receive filtered dust, the dust collection bin should be fixed to the mounting space in the vacuum cleaner in such a manner that the dust collection bin is neither shaken nor released, and when the dust fills the dust collection bin to some extent, the dust collection bin should be removed from the mounting space so as to throw away the collected dust.
- In particular, an upright type vacuum cleaner employs a lifting/lowering unit for use in lifting or lowering a dust collection bin within a mounting space so as to mount or remove the dust collection bin. Such a lifting/lowering unit is mounted on the bottom wall of the mounting space formed on the cleaner body so that when the lifting/lowering unit is lifted from the bottom of the mounting space, it pushes the dust collection bin upward, thereby making the dust collection bin come into close contact with a cyclone cylinder so as to fix the dust collection bin in such a manner as to be unmovable, or when the lifting/lowering unit is lowered and thus returned to its original position, the dust collection bin is spaced from the cyclone cylinder.
- The publication of Korean Patent No. 433407 owned by the applicant also discloses a vacuum cleaner, wherein a lifting/lowering unit is installed on the bottom wall of a mounting space for receiving a dust collection device, the mounting space being formed on the cleaner body of the vacuum cleaner, and a dust collection bin, which is laid on the top of the lifting/lowering unit, comes into close contact with the cyclone cylinder or is spaced from the cyclone cylinder as a lever part is rotated left or right. However, because an air tubing, which is provided within the vacuum cleaner, and through which air from the cyclone cylinder is discharged, is curved toward the cleaner body of the vacuum cleaner, the flow passage for discharge air is increased, which results in a pressure loss. In addition, the cyclone cylinder is mounted in the mounting space and only the dust collection bin is removable. Therefore, there was a disadvantage in that when the dust collection bin is removed, dust or the like deposited on the inner wall of the cyclone cylinder drops, thereby causing the pollution or even the malfunction of the lifting/lowering unit and reducing the lifetime of the lifting/lowering unit.
- The publication of Korean Patent No. 471142 also owned by the applicant also discloses a vacuum cleaner in which air discharged from a cyclone chamber is adapted to be discharged through the bottom wall of a dust collection bin so as to reduce the length of tubing for use in discharging air from the cyclone chamber, as a result of which the loss of pressure in the tubing can be reduced. However, with such a construction, it was difficult to apply a lifting/lowering unit for lifting and lowering the dust collection bin due to the leakage of air between the dust collection bin and the body of the vacuum cleaner, for which problem researches have been continuously made.
- Accordingly, aspects of the present disclosure are to address at least the above problems. Therefore, an aspect of the present disclosure is to provide a vacuum cleaner, which can reduce the pressure loss in a flow passage of discharge air as well as suppress the leakage of discharge air occurring in a lifting/lowering unit interposed between a dust collection bin and a cleaner body.
- Another aspect of the present disclosure is to provide a vacuum cleaner, which can reduce the pollution of a lifting/lowering unit, thereby reducing the malfunction of the lifting/lowering unit, as well as increasing the lifetime of the lifting/lowering unit.
- To achieve the above-described object, there is provided a vacuum cleaner comprising: a cleaner body formed with a mounting space; a vacuum motor mounted in the cleaner body to produce suction force; a brush assembly connected to the cleaner body; a dust collection device mounted in the mounting space and having a dust collection bin; and a lifting/lowering unit for lifting or lowering the dust collection bin in relation to the cleaner body, so that the dust collection bin is anchored in the mounting space or removed from the mounting space, wherein the lifting/lowering unit is mounted on the outer bottom surface of the dust collection bin so that it can be mounted in the mounting space or removed from the mounting space along with the dust collection bin.
- With this arrangement, because the lifting/lowering unit is mounted on the outer bottom surface of the dust collection bin, when it moves downward, the dust collection bin comes into close contact with the cyclone cylinder, and when it moves upward to its original position (toward the outer bottom surface of the dust collection bin), the cyclone cylinder and the dust collection bin are spaced from each other. As a result, the leakage of discharge air can be effectively prevented. In addition, because the lifting/lowering unit mounted on the outer bottom surface of the dust collection bin, the lifting/lowering unit can be removed along with the dust collection bin when the dust collection bin is removed. As a result, the pollution of the lifting/lowering unit and the malfunction of the lifting/lowering unit caused by the pollution can be avoided or at least reduced.
- Here, it is preferable that the outer bottom surface of the dust collection bin is formed with a recess and the lifting/lowering unit is fitted in the recess.
- In addition, the lifting/lowering unit may comprise: a lifting/lowering control member fitted in the recess; and a plurality of cam guides which are provided on the lifting/lowering control member and the outer bottom surface of the dust collection bin, respectively. The lifting/lowering control member may comprise a lever part capable of being gripped by a hand, and a body part integrally formed with the lever part. The cam guides may comprise first and second cam guides projecting from the outer bottom surface of the dust collection bin, and third and fourth cam guides projecting from the body part in such a manner as to be engaged with the first and second cam guides.
- In addition, the cam guides may further comprise a fifth cam guide projecting from the outer bottom surface of the dust collection bin in such a manner as to come into contact with the lever part, thereby separating the lever part from the outer bottom surface of the dust collection bin.
- According to another embodiment of the present disclosure, an air outlet port is formed through the bottom wall of the dust collection bin and a bore is formed in the lifting/lowering unit, so that air purified in the dust collection device is introduced into a motor chamber, within which the vacuum motor is installed, via the air outlet port and the bore.

InFIG. 2 ,reference numeral 28 indicates a filter unit,reference numeral 28 a indicates a skirt for interrupting the backflow of dust or dirt, andreference numeral 42 indicates an anti-rotation member for preventing the dust stored in thedust collection bin 23 from being rotated by swirling airflow. - Referring to
FIGS. 2 to 6 , the lifting/loweringunit 30 comprises a plurality ofcam guides control member 25, and first and secondcentral pipes unit 30 is mounted on the outer bottom surface of thedust collection bin 23, and when thedust collection bin 23 is positioned in themounting space 9, the lifting/loweringunit 30 comes into close contact with thebottom wall 10 a of themounting space 9. By increasing or decreasing the gap L1 between thebottom wall 10 a and the bottom surface of the lifting/loweringunit 30, the lifting/loweringunit 30 lifts or lowers thedust collection bin 23 in relation to thebottom wall 10 a of themounting space 9. When the lifting/loweringunit 30 presses on thebottom wall 10 a, thereby lifting thedust collection bin 23 to increase the gap L1 between the bottom surface of thecollection bin 23 and thebottom wall 10 a, thedust collection bin 23 comes into close contact with the outer bottom surface of thecyclone cylinder 21. In contrast, when the lifting/loweringunit 30 decreases the gap L1 between the bottom surface of thedust collection bin 23 and thebottom wall 10 a, thereby lowering thedust collection bin 23, thedust collection bin 23 can be spaced from thecyclone cylinder 21, so that thedust collection bin 23 can be pulled out from themounting space 9. - The cam guides comprise first to
fifth cam guides first cam guide 23 e and thesecond cam guide 23 f project from the outer bottom surface of thedust collection bin 23 along the circumference of theoutlet port 27 in such a manner as to surround the firstcentral pipe 23 d. Thefifth cam guide 23 g has the same circular arc as thefirst recess 23 a and is projectedly formed in thesecond recess 23 b. Due to thefifth cam guide 23 g, when the lifting/loweringcontrol member 25 rotates, a part of the top surface of thelever part 25 b comes into slidable contact with thefifth cam guide 23 g, thereby maintaining the gap between the outer bottom surface 23-1 of thedust collection bin 23 and the top surface of thelever part 25 b. As a result, when thebody part 25 a is spaced away from the outer bottom surface 23-1 by coming into contact with the first andsecond cam guides lever part 25 b is likewise spaced from the outer bottom surface 23-1 by coming into contact with thefifth cam guide 23 g, whereby the lifting/loweringcontrol member 25 can be stably rotated. The third and fourth cam guides 25 g and 25 h are formed on the lifting/loweringcontrol member 25, wherein the third and fourth cam guides 25 g and 25 h are engaged and rotated with the first and second cam guides 23 e and 23 f, respectively. - The lifting/lowering
control member 25 consists of abody part 25 a and alever part 25 b. Thebody part 25 a is formed in a circular shape and thelever part 25 b extends from the circumference of thebody part 25 a to a side of thebody part 25 a. Thebody part 25 a has a secondcentral pipe 25 f, which is formed on one of the bottom and top surfaces of thebody part 25 a in such a manner as to be capable of being inserted into the firstcentral pipe 23 d, wherein the secondcentral pipe 25 f has abore 25 e formed through the secondcentral pipe 25 f. Thebore 25 e formed through thebody part 25 a is communicated with theoutlet port 27 formed in thedust collection bin 23, so that air can be discharged to themotor chamber 10 b. If thebody part 25 a is rotated in one direction or the other direction, thefirst cam guide 23 e and thesecond cam guide 23 f are engaged and rotated with the third cam guide 25 g and thefourth cam guide 25 h, respectively, thereby lifting or lowering thedust collection bin 23. Referring toFIGS. 5 and 6 , on the circumference of thebody part 25 a, there are formed third andfourth recesses lever part 25 b, wherein the top wall of each of therecesses inclined guide wall 26 a and ahorizontal guide wall 26 b, which extends horizontally from the upper end of the inclined guide wall.FIG. 5 shows only thethird recess 25 c and theguide walls fourth recess 25 d and the guide walls thereof, which are not shown inFIG. 5 , are formed in the same construction as thethird recess 25 c and the guide walls thereof opposite to thethird recess 25 c and the guide walls thereof. - Referring to
FIGS. 3 , 4, and 7 to 9, thedust collection bin 23 is provided with at least two anchoring members so as to allow the lifting/loweringcontrol member 25 to be engaged with thedust collection bin 23, wherein the anchoring members include first and second anchoring screws 31 and 33, which have heads 31 a and 33 a, respectively. When the first and second anchoring screws 31 and 33 are provided on thedust collection bin 23, theheads 31 a and 33 b are partially inserted into the third andfourth recesses control member 25 is inserted into the first andsecond recesses dust collection bin 23, theheads 31 a and 33 a of the first and second anchoring screws 31 and 33 are partially inserted into the third andfourth recesses control member 25 is in a semi-restrained condition, thereby being prevented from being released downward away from thedust collection bin 23. - Now, the movement of the
dust collection bin 23, which is caused by the lifting/loweringunit 30 according to the first embodiment of the present disclosure, is described with reference toFIGS. 1 to 9 . - In a state in which the
lever part 25 d is not rotated as shown inFIG. 7 , the heads 3 la and 33 a of the first and second anchoring screws 31 and 33 are positioned at the lower most ends of theinclined guide walls 26 a. If thelever part 25 b is rotated in a direction for lifting thedust collection bin 23, the first and second cam guides 23 e and 23 f and the third and fourth cam guides 25 g and 25 h cooperatively slide in relation to each other, thereby lifting thedust collection bin 23, as a result of which the lifting/loweringcollection member 25 is relatively lowered in relation to thedust collection bin 23. At this time, the heads 3 la and 33 a of the first and second anchoring screws 31 and 33 are slid along theinclined guide walls 26 a. Thereafter, if thelever part 25 b is further rotated forward so as to maintain the lifted condition of thedust collection bin 23 after the lifting of thedust collection bin 23 is terminated, theheads 31 a and 33 a are moved along thehorizontal guide walls 26 b and positioned as shown inFIG. 9 . - In this manner, because the lifting/lowering
control member 25 for rendering thedust collection bin 23 to be engaged with the outer bottom surface of thecyclone cylinder 21 is provided on the outer bottom surface 23-1 of thedust collection bin 23 rather than on thecleaner body 10, if thelever part 25 b is rotated in the direction for lifting the lifting/loweringcontrol member 25, thedust collection bin 23 is lifted and the lifting/loweringcontrol member 25 is lowered in relation to thedust collection bin 23. Consequently, thedust collection bin 23 is lifted and comes into close contact with the lower end of thecyclone bin 21, and the lifting/loweringcontrol member 25 is lowered so as to compresses thebottom wall 10 a of the mounting space 9 (seeFIG. 2 ), whereby no gap is produced between the lifting/loweringunit 30 and thebottom wall 10 a of the mountingspace 9. According to the prior art, such a lifting/loweringunit 30 is provided on the bottom wall of the mounting space. Therefore, in order to cause the dust collection bin mounted on the lifting/lowering unit to be lifted and come into close contact with the cyclone cylinder, the lifting/lowering control member moves upward and presses the dust collection bin upward. Consequently, a gap is produced between the lifting/lowering unit and the bottom wall of the mounting surface to the extent the lifting/lowering control member is upwardly moved. However, according to the present embodiment, the lifting/loweringunit 30 is provided on the bottom side of thedust collection bin 23, so that the lifting/loweringcontrol member 25 is moved and presses against thebottom wall 10 a of the mountingspace 9. Therefore, no gap is produced between thebottom wall 10 a of the mountingspace 9 and the lifting/loweringunit 30, thereby preventing the leakage of discharge air. Referring toFIG. 2 , themotor chamber 10 b formed on thecleaner body 10 and the lifting/loweringunit 30 are sealed substantially without a gap L2 between them, so that clean air, from which dust has been removed in thecyclone cylinder 21, is all directed toward themotor chamber 10 b via theoutlet port 27 without leaking out through the gap L2, whereby a pressure loss caused by the leakage of air can be reduced. In addition, because the first and secondcentral pipes unit 30 is mounted on the bottom side of thedust collection bin 23, even if dirt drops from thecyclone cylinder 21 after thedust collection bin 23 has been removed from the mountingspace 9, the dirt drops on thebottom wall 10 a of the mountingspace 9, thereby preventing the pollution and malfunction of the lifting/loweringunit 30 and increasing an ease of cleaning of thecleaner body 10. - Now, a
vacuum cleaner 110 according to a second embodiment of the present disclosure is described with reference toFIGS. 10 to 12 . Here, component parts performing similar or analogous functions as the first embodiment are labeled in multiples of one hundred. - The second embodiment is different from the first embodiment in that a discharge flow passage P is provided within the
cleaner body 110 for communicating themotor chamber 110 b and thecyclone cylinder 121 in order to discharge air, from which dust has been removed in thecyclone cylinder 121, to themotor chamber 110 b. That is, the second embodiment is constructed in such a manner that the air of thecyclone cylinder 121 is adapted to be introduced into themotor chamber 110 b through the discharge flow passage P, unlike the first embodiment which is provided with an outlet tube and anoutlet port 27, which are formed in thedust collection bin 23, and abore 25 e, which is formed in the lifting/loweringunit 30. Referring toFIG. 11 , no outlet port is formed through the bottom wall of thedust collection bin 123 and a cylindricalrotary shaft 123 c extends from the bottom part of thedust collection bin 123. Referring toFIG. 12 , the central area of thebody part 125 a of the lifting/loweringcontrol member 125 is provided with a small cylinder 125-1, into which therotary shaft 123 c can be inserted, without being formed with an opening. Therotary shaft 123 c is inserted into the cylinder 125-1 so as to center the lifting/loweringcontrol member 125, when thecontrol member 125 is rotated. The other components of the second embodiment are equal to those of the first embodiment. Therefore, reference numerals and description thereof are omitted. - According to the second embodiment described above, the dust collection device for a vacuum cleaner is configured in such a manner that lifting/lowering
control member 125 is mounted on the bottom side of adust collection bin 123 so that the dust collection bin and the lifting/lowering control member are movable to push away one another. As a result, no gap is produced between the lifting/loweringcontrol member 125 and amotor chamber 110 b, whereby discharge air is completely blocked not to leak out. Furthermore, because the air is discharged through the bottom end of thecyclone cylinder 121 without leaking out, it is possible to reduce the length of the discharge flow passage P can be shortened as well as to reduce a pressure loss caused by the leakage of air from the vacuum cleaner. - In addition, because the lifting/lowering
control member 125 is mounted on the outer bottom surface of thedust collection bin 123, dust dropping from thecyclone cylinder 121 is not introduced into the lifting/loweringunit 130 even if thedust collection bin 123 is removed from thecyclone cylinder 121. As a result, it is possible to maintain the performance of the lifting/loweringunit 130, to prevent the malfunction of the lifting/lowering unit and to increasing the lifetime of the lifting/lowering unit. - While the disclosure 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 disclosure as defined by the appended claims.
