main body 30 having abody inlet 31, abody outlet 32, and a mountingpart 33 formed thereon; a motor assembly 40 (seeFIG. 9 ) disposed in themain body 30 to force air induced into themain body 30 through thebody inlet 31 to be discharged outside through thebody outlet 32; adust container 50 detachably mounted on the mountingpart 33 to filter foreign matter from air which enters themain body 30 through thebody inlet 31; a drivingunit 60 detachably mounted on the mountingpart 33 and coupled to thedust container 50 to generate a suction force in thedust container 50 when thedust container 50 is detached from themain body 30; and a power supply device 90 (seeFIG. 19 ) provided to themain body 30 and the drivingunit 60. - When power is supplied to the vacuum cleaner with the
dust container 50 and the drivingunit 60 mounted on themain body 30, themotor assembly 40 is driven to force air to be induced into themain body 30 through anozzle 110 via an extension duct (not shown) connected to thebody inlet 31. - Then, with foreign matter separated from air in the
dust container 50, air is discharged to the outside through thebody outlet 32, thereby enabling a vacuuming operation of the vacuum cleaner. - Electrical power is stored in the driving
unit 60 via thepower supply device 90. Thus, with thedust container 50 and the drivingunit 60 separated from themain body 30 and coupled to each other, the drivingunit 60 can be operated by turning on apower switch 67, enabling a vacuuming operation of a handy cleaner. - Here, since a principle of storing the electrical power in the driving
unit 60 via thepower supply device 90 is the same as that of a typical recharger, a detailed description thereof will be omitted herein. - The
body inlet 31 is formed at a front central region of themain body 30, and thebody outlet 32 is formed at one side on the rear of themain body 30. Themotor assembly 40 is located inside thebody outlet 32. - The mounting
part 33 includes a first mountingpart 35 depressed on one side of themain body 30 with respect to the center of themain body 30, and a second mountingpart 36 depressed on the other side of themain body 30. - After being induced into the
main body 30 through thebody inlet 31, air is removed of foreign matter while passing through thedust container 50 mounted on the first mountingpart 35, and is then discharged to the outside through thebody outlet 32 by themotor assembly 40. - Referring to FIGS. 10 to 14, and 22, the
dust container 50 includes acase 51 defining a closed space therein; acover 52 provided to one side of thecase 51 and having anintake port 55 and anexhaust port 56; afilter 57 provided to theexhaust port 56; aknob 53 extending from one side of thecover 52; a knob-cover 54 provided to theknob 53; and a first mounting device 80 a provided to theknob 53 and the knob-cover 54 to couple thedust container 50 to the first mountingpart 35. - A
curved guide duct 55 a is located inside theintake port 55 and extends to partially surround thefilter 57. - After being sucked into the
main body 30 through thebody inlet 31, air is induced into thedust container 50 through theintake port 55, filtered of foreign matter by thefilter 57 in thedust container 50, and is discharged again into themain body 30 through theexhaust port 56. - After being discharged into the
main body 30, air is finally discharged to the outside through thebody outlet 32 by themotor assembly 40. - In order to constitute an air path as described above, the first mounting
part 35 is formed with adischarge port 35 a corresponding to theintake port 55 and communicated with thebody inlet 31, and formed with asuction port 35 b corresponding to theexhaust port 56 and communicated with thebody outlet 32. - Referring to
FIGS. 4, 11 and 16, the mountingdevice 80 includes the first mounting device 80 a provided to thedust container 50, a second mounting device 80 b provided to the first mountingpart 35 and coupled to the first mounting device 80 a, and a third mounting device 80 c provided to the drivingunit 60 and coupled to the first mounting device 80 a. - The first mounting device 80 a includes a
latch protrusion 84 configured to be inserted into or protrude from thecover 52, a knob-button 82 movably provided to theknob 53 to move thelatch protrusion 84 into thecover 52, and an elastic member (not shown) disposed between thelatch protrusion 84 and an inner wall of theknob 53 to apply force to thelatch protrusion 84 toward agroove 35 c. - The second mounting device 80 b includes a
groove 35 c formed corresponding to thelatch protrusion 84 on the first mountingpart 35, and the third mounting device 80 c includes agroove 68 formed corresponding to thelatch protrusion 84 on the drivingunit 60. - Referring to
FIGS. 4 and 22 , afirst connection device 70 is provided to thedust container 50 and the first mountingpart 35. Thefirst connection device 70 includes acircular jaw 72 extending outward from the periphery of theexhaust port 56, a slidingprotrusion 74 protruding from an end of thejaw 72 in a lateral direction, acircular insertion groove 76 formed corresponding to thejaw 72 around the periphery of thesuction port 35 b, acatch protrusion 77 formed at an outer end of theinsertion groove 76 to catch the slidingprotrusion 74, and a sealing member (not shown) of an elastic material fitted into theinsertion groove 76. - When mounting the
dust container 50 on the first mountingpart 35, thedust container 50 is inclined at a predetermined angle on the first mountingpart 35 so as to prevent the slidingprotrusion 74 from interfering with thecatch protrusion 77, and thejaw 72 is inserted into theinsertion groove 76. Then, thedust container 50 is rotated and seated on the first mountingpart 35. - At this time, the sliding
protrusion 74 is slid along theinsertion groove 76 and is then disposed between thecatch protrusion 77 and theinsertion groove 76 by the rotation of thedust container 50, which leads to a close contact between theexhaust port 56 and thesuction port 35 b. - Further, when the
dust container 50 is rotated, the elastic member (not shown) is compressed to allow thelatch protrusion 84 to be inserted into thecover 52. Then, when thedust container 50 is mounted on the first mountingpart 35, thelatch protrusion 84 protrudes from thecover 52 by a restoration force of the elastic member and inserted into thegroove 35 c, thereby restricting the rotation of thedust container 50 to prevent separation of thedust container 50 from themain body 30. - The driving
unit 60 is detachably mounted on the second mountingpart 36 and has asuction device 61, so that when thedust container 50 is separated from the first mountingpart 35, the drivingunit 60 can be coupled to thedust container 50 to constitute the handy cleaner. - The driving
unit 60 is provided with asuction duct 62 for sucking air, and anexhaust opening 63 for discharging air from which foreign matter is removed. - The driving
unit 60 is formed with adischarge port 64 that corresponds to theintake port 55 of thedust container 50 and communicates with thesuction duct 62. - The driving
unit 60 is formed with asuction port 65 that corresponds to theexhaust port 56 of thedust container 50 and communicates with theexhaust opening 63. - Referring to
FIGS. 5 and 11 , the mountingdevice 80′ provided to thedust container 50 and drivingunit 60 includes alatch protrusion 84′ capable of being inserted into or protruding from the surface of thecover 52, agroove 68′ formed corresponding to thelatch protrusion 84′ on the drivingunit 60, a knob-button 82′ movably provided to theknob 53 to allow thelatch protrusion 84′ to be inserted into thecover 52 when pushed down by the user, and an elastic member (not shown) disposed between thelatch protrusion 84′ and an inner wall of theknob 53 to allow thelatch protrusion 84′ to be inserted into thegroove 68′. - Referring to
FIGS. 5 and 22 , asecond connection device 70′ having the same configuration as that of thefirst connection device 70 is provided to thedust container 50 and drivingunit 60. - The
second connection device 70′ includes acircular jaw 72′ extending outward from the periphery of theexhaust port 56, a slidingprotrusion 74′ protruding from the end of thejaw 72′ in the lateral direction, acircular insertion groove 76′ formed corresponding to thejaw 72′ around the periphery of thesuction port 65, acatch protrusion 77′ formed at the outer end of theinsertion groove 76′ to catch the slidingprotrusion 74′, and a sealing member (not shown) of an elastic material fitted into theinsertion groove 76′. - When coupling the
dust container 50, separated from the first mountingpart 35, to the drivingunit 60, thedust container 50 is inclined at a predetermined angle with respect to the drivingunit 60 so as to prevent the slidingprotrusion 74′ from interfering with thecatch protrusion 77′, and thejaw 72′ is inserted into theinsertion groove 76′. Then, thedust container 50 is rotated to be coupled to the drivingunit 60. - At this time, the sliding
protrusion 74′ is slid along theinsertion groove 76′ and is then disposed between thecatch protrusion 77′ and theinsertion groove 76′ by the rotation of thedust container 50, which leads to a close contact between theexhaust port 56 and thesuction port 65. - Further, when the
dust container 50 is rotated, the elastic member (not shown) is compressed to allow thelatch protrusion 84′ to be inserted into thecover 52. Then, when thedust container 50 is coupled to the drivingunit 60, thelatch protrusion 84′ protrudes from thecover 52 by the restoration force of the elastic member and inserted into thegroove 68, thereby restricting the rotation of thedust container 50 to prevent separation of thedust container 50 from the drivingunit 60. - Referring to FIGS. 18 to 21, the
power supply device 90 includes a terminal 92 formed on an inner wall of the second mountingpart 36 to supply electrical power, acontact point 94 formed corresponding to the terminal 92 on the drivingunit 60, and abattery 96 to store electrical power supplied through thecontact point 94 and to supply the electrical power to thesuction device 61. - The
battery 96 is received in abattery case 99, which is detachably coupled to the drivingunit 60, such that thebattery 96 can store electrical power supplied through thecontact point 94 and supply the electrical power to thesuction device 61. - A
coupling device 100 is provided to the drivingunit 60 and thebattery case 99 to allow detachable coupling of thebattery case 99 to the drivingunit 60, and acoupling recess 66 is formed on the drivingunit 60 to receive thebattery case 99. - Referring to FIGS. 16 to 18, the
coupling device 100 includes a holdinggroove 102 formed on thebattery case 99, alever 104 having acoupling protrusion 105 formed corresponding to the holdinggroove 102 at one end of thelever 104 such that thelever 104 can be hingably coupled to thecoupling recess 66 of the drivingunit 60, an elastic member (not shown) disposed between thelever 104 and thecoupling recess 66, aconnection terminal 108 provided to an inner wall of thecoupling recess 66 to supply electrical power to thesuction device 61, and acoupling portion 109 provided to thebattery case 99 and corresponding to theconnection terminal 108. - Here, since the other end of the lever is located outside the
battery case 99, thecoupling protrusion 105 can be separated outside the holdinggroove 102 by pushing the other end of thelever 104 when separating thebattery case 99 from thecoupling recess 66 of the drivingunit 60. - When coupling the
battery case 99 to the drivingunit 60, thebattery case 99 having a plurality ofbatteries 96 is inserted into thecoupling recess 66. Then, the elastic member is compressed to force thecoupling protrusion 105 to be pushed out of thecoupling recess 66, so thebattery case 99 is seated on thecoupling recess 66. When thebattery case 99 is inserted into thecoupling recess 66, thelever 104 is rotated by the restoration force of the elastic member, allowing thecoupling protrusion 105 to be inserted into the holdinggroove 102. As a result, thebattery case 99 can be completely mounted to the drivingunit 60. - Then, when the driving
unit 60 is mounted on the second mountingpart 36, the terminal 92 is electrically connected to thecontact point 94 so that the electrical power can be stored in thebatteries 96. - Referring to
FIG. 25 , thepower supply device 90 includes a recharging printed circuit board (PCB) 98 connected in parallel to a drivingPCB 98 a to supply electrical power to the terminal 92. - The driving
PCB 98 a is a PCB to determine whether or not power is to be supplied to themotor assembly 40. - Therefore, when the driving
unit 60 is mounted on the second mountingpart 36 with thebattery case 99 coupled to the drivingunit 60, the terminal 92 is brought into contact with thecontact point 94 to obtain an electrical connection therebetween. - At this time, electrical power is stored in the
batteries 96 via the rechargingPCB 98. - The recharging
PCB 98 is connected in parallel between apower plug 97 and the drivingPCB 98 a. Thus, when power is applied to the drivingPCB 98 a by coupling thepower plug 97 to a wall socket (not shown), the power is also applied to the rechargingPCB 98, thereby accomplishing a charging operation. - As such, when the
power plug 97 is coupled to the wall socket with the drivingunit 60 mounted on the second mountingpart 36, thebatteries 96 can be charged irrespective of whether or not themotor assembly 40 is driven, so that the handy cleaner can be prepared for the vacuuming operation. - Additionally, since the vacuum cleaner further includes a
recharger 99 a connected to thebattery case 99 separated from the drivingunit 60 to supply electrical power, thebatteries 96 can be easily charged even in the case of employing only the handy cleaner constituted by coupling the drivingunit 60 to thedust container 50. - Referring to
FIGS. 23 and 24 , the technical constitution described above is to filter foreign matter from air by thedust container 50 when the air is sucked into themain body 30 through thebody inlet 31. At this time, an extension duct (not shown) is provided to thebody inlet 31, and is selectively provided at one end with one ofnozzles 110, which may have various shapes, enabling effective vacuuming operations at various locations. - In order to accommodate the
nozzles 110 of the various shapes, anaccommodation part 34 is formed on the bottom of themain body 30 and has a plurality ofaccommodation grooves 39 corresponding to the shapes of thenozzles 110 on an inner wall of theaccommodation part 34. - Further, to prevent the
nozzles 110 from being detached from theaccommodation grooves 39 of theaccommodation part 34, alid 37 is hingably coupled at one end to an edge of theaccommodation part 34, and an opening-closingdevice 38 is provided to the other end of thelid 37 and theaccommodation part 34. - The opening-closing
device 38 includes ahook protrusion 38 a formed on thelid 37, and afastening groove 38 b formed on theaccommodation part 34 such that thehook protrusion 38 a is fitted into thehook protrusion 38 a. - When the
hook protrusion 38 a is inserted into thefastening groove 38 b by rotating thelid 37 with thenozzles 110 fitted into theaccommodation grooves 39, thehook protrusion 38 a is suppressed from being released from thefastening groove 38 b, which prevents thelid 37 from being open. - The
fastening groove 38 b is a typical fastening means to hold a protrusion inserted thereto in one-touch manner, and thus a detailed description thereof will be omitted herein. - When converting the vacuum cleaner constructed as above into the handy cleaner for the vacuuming operation, the
dust container 50 is coupled to the drivingunit 60 to constitute the handy cleaner, in which thesuction duct 62 is drawably provided to the drivingunit 60 to suck air and foreign matter during the vacuuming operation. - Further, when mounting the driving
unit 60 and thedust container 50 on themain body 30, thesuction duct 62 is located so as not to protrude from the drivingunit 60, allowing the drivingunit 60 anddust container 50 to be easily mounted thereon. - Such a
suction duct 62 is rotatably provided to ahole 62 a communicated with thedischarge port 64, and is constituted by a curved pipe. Therefore, when the drivingunit 60 is mounted on the second mountingpart 36, thesuction duct 62 is rotated so as to be brought into close contact with the lower surface of the drivingunit 60 so that the drivingunit 60 can be easily mounted on the second mountingpart 36. - Additionally, the second mounting
part 36 is formed with a curved seat groove 36 a (seeFIG. 19 ) on the bottom of the second mountingpart 36 corresponding to thesuction duct 62, thereby allowing easier mounting of the drivingunit 60 on themain body 30. - Next, operation of the vacuum cleaner constructed as above according to the an embodiment of the present invention will be described.
- First, when vacuuming a large area with the vacuum cleaner, the
jaw 72 is inserted into theinsertion groove 76 of the first mountingpart 35, with thedust container 50 slanted at a predetermined angle on the first mountingpart 35. Then, by rotating thedust container 50 into the first mountingpart 35, the slidingprotrusion 74 is rotated along theinsertion groove 76 and is then fitted between thecatch protrusion 77 and theinsertion groove 76, so thedust container 50 is coupled to the first mountingpart 35. - Further, after being rotated downwardly and brought into close contact with the lower surface of the driving
unit 60, thesuction duct 62 of the drivingunit 60 is inserted into the seat groove 36 a on the second mountingpart 36, allowing the drivingunit 60 to be mounted on the second mountingpart 36 with the terminal 92 electrically connected to thecontact point 94. - With the
dust container 50 and drivingunit 60 mounted on the main body of the vacuum cleaner as described above, thepower plug 97 is pulled out of themain body 30 and connected to a wall socket to supply electrical power to the drivingPCB 98 a and the rechargingPCB 98, thereby charging thebatteries 96. - Of course, even in a state where the driving
unit 60 is not mounted on the second mountingpart 36, the vacuum cleaner can be driven since power is applied to themotor assembly 40. - Then, when a user starts vacuum cleaning, power is supplied from the driving
PCB 98 a to themotor assembly 40 to generate a suction force, which causes air to be induced through one of thenozzles 110 and the extension duct (not shown). - After being induced into the
main body 30 through thebody inlet 31, air flows into thedust container 50 along thedischarge port 35 a,intake port 55, and aguide duct 55 a. - After being induced into the
dust container 50, air flows from the periphery of thefilter 57 to the center thereof, during which foreign matter is removed from the air by thefilter 57. - The air filtered of the foreign matter flows again to a
flow passage 32 a defined at the central region of themain body 30 through theexhaust port 56 andsuction port 35 b. - In this manner, as air is discharged from the
main body 30 through thebody outlet 32 via themotor assembly 40, the vacuuming operation of the vacuum cleaner can be performed. - With such an operation as described above, the vacuum cleaner is used to vacuum the large area.
- Next, when vacuuming narrow areas such as a gap between pieces of furniture, a channel of a door, etc., it can be accomplished by preparing the handy cleaner after separating the
dust container 50 and the drivingunit 60 from themain body 30. - When the user pushes down the knob-
button 82 to constitute the handy cleaner, the elastic member (not shown) is compressed to allow thelatch protrusion 84 to be inserted into the knob-cover 54. Then, by rotating theknob 53 upwardly with the knob-button 82 pushed down, thedust container 50 is rotated and the slidingprotrusion 74 is released from thecatch protrusion 77. - As a result, the
dust container 50 can be separated from the first mountingpart 35. - Then, the separated
dust container 50 is connected to the drivingunit 60 separated from the second mountingpart 36 as in the manner of connecting thedust container 50 to the first mountingpart 35, thereby constituting the handy cleaner. - Finally, by rotating the
suction duct 62 closely contacting the lower surface of the drivingunit 60 forwardly, thehole 62 a of the drivingunit 60 formed corresponding to thesuction duct 62 is connected to thesuction duct 62, and thesuction duct 62 is thus communicated with thedischarge port 64. - When turning on the
power switch 67 of the handy cleaner constituted as described above, thesuction device 61 is driven to force air to be sucked into the handy cleaner along thesuction duct 62, and the sucked air flows into thedust container 50 through thedischarge port 64 andintake port 55. - After being induced into the
dust container 50, air flows from the periphery of thefilter 57 to the center thereof, during which foreign matter is removed from the air by thefilter 57. - The air filtered of the foreign matter flows again to the driving
unit 60 through theexhaust port 56 andsuction port 65, and is then discharged from the drivingunit 60 through theexhaust opening 63 via thesuction device 61. - In this manner, the vacuuming operation of the handy cleaner is performed.
- In order to allow the vacuuming operation of the handy cleaner to be performed for a long period of time, the
batteries 96 is recharged. First, thedust container 50 is separated from the drivingunit 60 as in the method of separating thedust container 50, and the separated drivingunit 60 is mounted on the second mountingpart 36. - As a result, the terminal 92 is brought into contact with and electrically connected to the
contact point 94, electrical power is supplied from the rechargingPCB 98 to the drivingunit 60, and thereby charges thebatteries 96. - In order to charge the
batteries 96 without separating the drivingunit 60 from thedust container 50, thelever 104 is pushed down to allow thecoupling protrusion 105 to be released from the holdinggroove 102. - Next, after taking the
battery case 99 out of the drivingunit 60, the charging operation of thebatteries 96 can be performed by connecting therecharger 99 a to thecoupling portion 109. - The handy cleaner-integrated vacuum cleaner according to an embodiment of the present invention has been described above. However, it should be noted that the present invention is not limited to this embodiment of the vacuum cleaner. For example, a vacuum cleaner can be constituted by the
main body 30, themotor assembly 40, and thedust container 50 without the drivingunit 60, and can be used to perform the vacuuming operation of the vacuum cleaner described above. - Further, a handy cleaner can be constituted by a driving
unit 60, adust container 50 and arecharger 99 a without themain body 30 and themotor assembly 40 of the vacuum cleaner according to an embodiment of the invention, and can be used to perform the vacuuming operation of the handy cleaner described above. - Such a handy cleaner includes the
dust container 50 having anintake port 55 and anexhaust port 56, and afilter 57 located inside thedust container 50; the drivingunit 60 detachably attached to thedust container 50 to generate a suction force in thedust container 50; asuction duct 62 provided to the drivingunit 60 and communicated with theintake port 55; and anexhaust opening 63 formed in the drivingunit 60 and communicated with theexhaust port 56. - The
filter 57 has a cylindrical shape and is located inside theexhaust port 56. Theintake port 55 extends to partially surround thefilter 57 as shown inFIGS. 11 and 15 . - A
curved guide duct 55 a is located inside theintake port 55 of thedust container 50 and extends to partially surround thefilter 57. - With the handy cleaner including a cyclone type dust container constructed as described above, it is possible to perform vacuuming operation as in the handy cleaner.
- As apparent from the above description, in the handy cleaner and the vacuum cleaner including the same according to an embodiment of the present invention, a cyclone type dust container is disposed therein to prevent accumulated foreign matter from obstructing air flow, thereby increasing capacity of the dust container. Further, according to an embodiment of the present invention, the cyclone type dust container and a driving unit can be detachably coupled to the handy cleaner to allow conversion into the vacuum cleaner, thereby improving compatibility of the vacuum cleaner.
