Description
- This application claims priority from Korean Patent Application No. 2007-0086690, filed Aug. 28, 2007 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference.
- 1. Field of the Invention
- The present disclosure relates to a stick type vacuum cleaner, and more particularly, to a stick type vacuum cleaner, which has a power supply unit such as a battery of increased lifespan, and is capable of reducing noise level.
- 2. Description of the Related Art
- Vacuum cleaners are among the most widely used home electronic appliances. Vacuum cleaners draw in air and dust from a surface being cleaned, using a suction force generated by a vacuum source.
- A canister vacuum cleaner includes a main body, a suction port assembly, and a connecting part. The main body includes a suction force generating unit and a dust separating unit to separate dust from air and collect the separated dust. The suction force generating unit includes an impeller which is generally rotatably installed, and a suction motor to rotate the impeller. The suction port assembly moves along an object being cleaned, drawing in dust and air through a suction port. The connecting part connects the suction port assembly with the main body, and includes a handgrip, an extension pipe to connect the suction port assembly and the handgrip, and a flexible hose to connect the handgrip and the main body.
- The canister type vacuum cleaner includes a power line which is exposed to outside to supply power to the suction force generating unit. Generally, a plug formed on one end of the power line is inserted in a socket formed in walls of a room to supply power to the suction force generating unit.
- Meanwhile, a user of a canister type vacuum cleaner moves not only the suction port assembly, but also the main body engaged with the suction port assembly. While using the vacuum cleaner, the user has to be careful not to hit the objects nearby.
- A stick type vacuum cleaner is one of those cleaners that are proposed to overcome such inconveniences mentioned above. In terms of appearance, a stick type vacuum cleaner is similar to a canister type cleaner in that it includes a suction port assembly, an extension pipe and a handgrip. However, a stick type vacuum cleaner skips the main body, and instead accommodates a suction force generating unit and a dust separating unit in the suction port assembly. The suction port assembly of the stick type vacuum cleaner draws in dust using a suction force generated therefrom, and also collects the separated dust therein. Furthermore, the stick type vacuum cleaner usually accommodates a power supply unit such as a battery in the suction force generating unit to supply power to the suction force generating unit, and so does not require a separate power line.
- In most of stick type vacuum cleaners, a suction force generating unit is arranged at a rear portion of the dust separating unit. Accordingly, a vacuum pressure of the suction force generating unit is transmitted to the suction port via the dust separating unit. However, the dust separating unit can be damaged by the vacuum pressure being transmitted to the suction port. Therefore, the suction force generating unit has to rotate the impeller at relatively fast speed to overcome loss of pressure in the dust separating unit and to provide the suction port with sufficient suction force.
- When the suction force generating unit is arranged at a rear side of the cleaner like in the stick type vacuum cleaner, the suction force generating unit consumes a relatively large amount of power, causing decrease of life span of the power supply unit such as battery which supplies power to the suction force generating unit. Furthermore, the impeller generates offensive noise during its fast rotation.
- Exemplary embodiments of the present disclosure overcome the above disadvantages and other disadvantages not described above. Accordingly, it is an object of the present disclosure to provide a stick type vacuum cleaner which has a power supply unit of increased lifespan, and is capable of reducing noise level of the suction force generating unit.
- An aspect of the present disclosure provides a stick type vacuum cleaner which includes a suction port assembly movable along an object being cleaned to draw in dust and air from the object, and a stick unit in which a first end is engaged with a first side of the suction port assembly and a second end comprises a handgrip so that a user can grip the handgrip to move the suction port assembly along the object being cleaned. The suction port assembly may include a casing part comprising a suction port through which air and dust is drawn from the object being cleaned, a suction force generating unit formed inside the casing part to generate a suction force, a dust separating unit to separate dust from the drawn air and dust and accommodate the separated dust therein, and a power supply unit to supply power to the suction force generating unit. The suction force generating unit may be disposed between the suction port and the dust separating unit so that the drawn air and dust pass through the suction force generating unit before being introduced into the dust separating unit.
- The suction force generating unit may include an impeller disposed to be exposed to a passage defined between the suction port and the dust separating unit, to generate the suction force by rotational movement, and a suction motor to receive a power from the power supply unit and rotate the impeller.
- The dust separating unit may include a cyclone chamber to separate dust from the air and dust drawn through the suction port by using a centrifugal force, and a dust collecting chamber to accommodate the dust separated from the cyclone chamber.
- The dust separating unit may include a cyclone dust separating unit in which the cyclone chamber and the dust collecting chamber are arranged in parallel, in a manner such that a cyclone inlet is formed on a first end and the cyclone chamber and the dust collecting chamber are open in a second end, and a side cover to cover the second side of the cyclone dust separating unit, and comprising an air discharge pipe to guide the air to be discharged from the cyclone chamber.
- The dust separating unit may include a filter member formed on an outer surface of the side cover to filter remaining dust from the air being discharged from the cyclone chamber, and a filter support member removably formed on the outer surface of the side cover to support the filter member formed on the side cover.
- The filter support member may include at least one air passing hole.
- An upper side of the cyclone dust separating unit may be made out of a transparent material to enable a user to see the cyclone chamber and the dust collecting chamber therethrough.
- The casing part may include a dust separating unit chamber so that the dust separating unit is removably housed in the dust separating unit chamber.
- The suction port assembly may further include a rotatable brush movably formed in the suction port, and a rotatable brush motor to drive the rotatable brush.
- The rotatable brush motor may receive power from the power generating unit.
- The stick part may include an engaging part engaged to a first side of the suction port assembly, a stick type extension part extended from the engaging part, and a handgrip formed on one end of the stick-type extension part.
- The power generating unit may include a battery removably disposed inside the casing part.

Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
- Referring to
FIGS. 1 and 2 , a sticktype vacuum cleaner 1 according to an exemplary embodiment of the present disclosure includes asuction port assembly 100, and astick part 200. - The
suction port assembly 100 is disposed to be moved along an object being cleaned, and to draw in dust from the object and collect the drawn dust therein. Thestick part 200 is engaged with a rear portion of thesuction port assembly 100 to facilitate a user's operation of thesuction port assembly 100 along the object being cleaned. Thestick part 200 includes anengaging part 210 formed on a rear portion of thesuction port assembly 100, a stick-type extension part 220 extending from theengaging part 210, and ahandgrip 230 formed on an upper portion of the stick-type extension part 220. - Referring to
FIGS. 1 , 2 and 6, thesuction port assembly 100 includes acasing part 110, arotatable brush 120, arotatable brush motor 121, apower supply 130, a suction force generating unit 140, and a dust separatingunit 150. - Referring to
FIG. 1 , thecasing part 110 includes anupper casing 111 and alower casing 112. Theupper casing 111 includes a dust separating unit chamber S to receive thedust separating unit 150 therein. Theupper casing 111 also includes a plurality of air discharge holes 111 a formed in a rear portion to permit the clean air to be discharged outside thesuction port assembly 100 after the dust is separated in thedust separating unit 150. - Referring to
FIG. 6 , thelower casing 112 includes asuction port 112 a formed on the front portion. Dust and air can be drawn into thesuction port assembly 100 through thesuction port 112 a. - Referring to
FIGS. 2 and 6 , therotatable brush 120 is formed on the front portion of thelower casing 112, to be disposed in thesuction port 112 a. Therotatable brush 120 is rotated by therotatable brush motor 121, to hit with its lower portion the object being cleaned and remove dust from the object being cleaned. - The
rotatable brush motor 121 receives power supply from the power supply 130 (FIG. 6 ). Thepower supply 130 according to the exemplary embodiment of the present disclosure is implemented as areplaceable battery 130 mounted inside thecasing part 110. Thebattery 130 supplies power not only to therotatable brush motor 121, but also to asuction motor 141 which will be explained below. - Referring to
FIG. 2 , the suction force generating unit 140 includes thesuction motor 141, animpeller 142, and a suctionport connecting pipe 143. Thesuction motor 141 receives power from thebattery 130 to rotate theimpeller 142. Theimpeller 142 is rotated by thesuction motor 141 to generate a vacuum pressure, or suction force. The suctionport connecting pipe 143 connects thesuction port 112 a and theimpeller 142 to guide the air and dust drawn from the object being cleaned into theimpeller 142. - The
suction port assembly 100 includes the suction force generating unit 140 and thebattery 130 to supply power to the suction force generating unit 140 to generate a suction force. Thevacuum cleaner 1 according to the exemplary embodiment of the present disclosure does not need a power line to receive external power. - Referring again to
FIG. 2 , the suction force generating unit 140 is arranged in front of thedust separating unit 150. That is, the suction force generating unit 140 is provided between thesuction port 112 a and thedust separating unit 150. Air and dust is drawn through thesuction port 112 a, and then passes the suction force generating unit 140 and flows into thedust separating unit 150. More specifically, air and dust drawn through thesuction port 112 a flows into thedust separating unit 150 via theimpeller 142 provided in the suction force generating unit 140. Theimpeller 142 is arranged on a fluid passage that connects thesuction port 112 a and thedust separating unit 150 according to the exemplary embodiment of the present disclosure. Therefore, theimpeller 142 operates as a bypass impeller, while the motor to drive this bypass impeller operates as a bypass motor. - In comparison with a vacuum cleaner in which the suction force generating unit 140 is arranged in the rear portion of the
dust separating unit 150, the vacuum cleaner according to the exemplary embodiment of the present disclosure can provide almost unaffected level of suction force to thesuction port 112 a when thesuction motor 141 rotates theimpeller 142 with relatively slower speed. - Because the suction force generating unit 140 is arranged in front of the
dust separating unit 150, the vacuum pressure generated at the suction force generating unit 140 is transmitted to thesuction port 112 a intact, that is, without being affected by thedust separating unit 150. Furthermore, because the suction force generating unit 140 is arranged in front of thedust separating unit 150, theimpeller 142 of the suction force generating unit 140 is able to draw in dust and air introduced through thesuction port 112 a using not only vacuum pressure, but also mechanical friction. The mechanical friction of theimpeller 142 more specifically refers to a friction between air and dust with the rotating blades (not illustrated) of theimpeller 142, which provides a moving force in the direction of thedust separating unit 150. - If the suction force generating unit 140 is arranged in back of the
dust separating unit 150, the vacuum pressure generated by the suction force generating unit 140 can be transmitted to thesuction port 112 a via thedust separating unit 150. Accordingly, thedust separating unit 150 has the loss of vacuum pressure while the vacuum pressure is transmitted from the suction force generating unit 140 to thesuction port 112 a. Furthermore, if the suction force generating unit 140 is arranged in back of thedust separating unit 150, dust is filtered at thedust separating unit 150 already prior to arriving at the suction force generating unit 140, and therefore, it is impossible for theimpeller 142 to draw the dust into thedust separating unit 150 by mechanical friction. - As explained above, when the suction force generating unit 140 is provided in front of the
dust separating unit 150, theimpeller 142 can be rotated at a relatively slower speed than when the suction force generating unit 140 is provided in back of thedust separating unit 150, but without compromising the level of suction force provided to thesuction port 112 a. Because thesuction motor 141 consumes less power to rotate theimpeller 142, the lifespan of thebattery 130 to supply power to thesuction motor 141 can be increased. Furthermore, because the rotational speed of theimpeller 142 decreases, less amount of noise is generated from the rotation of theimpeller 142. - Referring to
FIGS. 1 and 3 , thedust separating unit 150 is removably mounted in the dust separating unit chamber (S) of theupper casing 111. Thedust separating unit 150 includes a cyclonedust separating unit 160, aside cover 170, afilter member 180, and afilter support member 190. - Referring to
FIG. 1 , the cyclonedust separating unit 160 includes acyclone inlet 162 formed in afirst side 160 a. The dust and air, after passing through the suction force generating unit 140, is introduced into thecyclone chamber 163 through thecyclone inlet 162. - Referring to
FIGS. 3 and 5 , the cyclonedust separating unit 160 includes acyclone chamber 163 and adust collecting chamber 164 both formed therein. Thecyclone chamber 163 separates, using a centrifugal force, dust from air that introduced through thecyclone inlet 162. Thedust collecting chamber 164 collects the dust separated from thecyclone chamber 163. Thecyclone chamber 163 and thedust collecting chamber 164 are arranged in parallel and divided from each other by asingle partition 165. Thecyclone chamber 163 and thedust collecting chamber 164 are open to asecond side 160 b of the cyclonedust separating unit 160. - The cyclone
dust separating unit 160 includes a dustseparating unit handgrip 161 formed on anupper side 160 c so that a user can grab it and carry thedust separating unit 150 with ease. Theupper side 160 c of the cyclonedust separating unit 160 may be made out of a transparent material to allow observance of thecyclone chamber 163 and thedust collecting chamber 164 from outside. Accordingly, a user is able to see and check the dust separating performance of thecyclone chamber 163 and also check the amount of dust collected in thedust collecting chamber 164, without having to disassemble thedust separating unit 150. - Referring to
FIGS. 3 and 4 , theside cover 170 covers thesecond side 160 b of the cyclonedust separating unit 160. Theside cover 170 is detachably formed on the cyclonedust separating unit 160. If thedust collecting chamber 164 is full, the user detaches theside cover 170 from the cyclonedust separating unit 160 and empty thedust collecting chamber 170. Theside cover 170 includes anair discharge pipe 171 formed thereon. Accordingly, clean air is discharged from thecyclone chamber 163 to thefilter member 180 through theair discharge pipe 171 when dust is separated from the air. - Referring to
FIG. 3 , thefilter member 180 is disposed on anouter side 172 of theside cover 170 to filter remaining dust from the air received from thecyclone chamber 163. - The
filter member 180 is supported by thefilter support member 190 to remain engaged with theside cover 170. Thefilter support member 190 is detachably engaged with theside cover 170. Accordingly, if thefilter member 180 gets too dusty, thefilter support member 190 along with thefilter member 180 is removed through theside cover 170 and a user can remove dust from thefilter member 180. Thefilter support member 190 includes a plurality ofair holes 191 for air to pass after passing through thefilter member 180. - The operation of a stick type vacuum cleaner constructed as above according to the exemplary embodiments of the present disclosure will be explained below with reference to
FIGS. 2 , 5 and 6. - As a user drives a stick
type vacuum cleaner 1, therotatable brush motor 121 receives power from thebattery 130 to rotate therotatable brush 120. At the same time, thesuction motor 141 also receives power from thebattery 130 to rotate theimpeller 142. The rotation of theimpeller 142 generates a suction force (vacuum pressure), which is provided to thesuction port 112 a through the suction port connecting pipe 143 (seeFIG. 2 ). - As explained above, because the suction force generating unit 140 having the
suction motor 141 and theimpeller 142 is arranged between thedust separating unit 150 and thesuction port 112 a, unaffected level of suction force can be provided to thesuction port 112 a even when thesuction motor 141 rotates theimpeller 142 at a relatively lower speed. As a result, thebattery 130 to supply power to thesuction motor 141 can be used for a longer period of time. Furthermore, because theimpeller 142 rotates at a relatively slower speed, noise is reduced. - During cleaning, as a user moves the
suction port assembly 100 along an object being cleaned, air and dust is drawn through thesuction port 112 a. Therotatable brush 120 hits the dust of the object being cleaned in rotating movement, to thereby facilitate the removal of the dust. As a result, more efficient cleaning is achieved. - The air and dust enters through the
suction port 112 a, and is introduced into theimpeller 142 through the suction port connecting pipe 143 (seeFIG. 2 ). The air and dust is then guided to the back of the cleaner by not only the suction force, but also the mechanical friction with theimpeller 142, and guided to thecyclone inlet 162 of the cyclonedust separating unit 160. Because the air and dust is introduced into thecyclone inlet 162 by both the suction force and mechanical friction, output of thesuction motor 141 to rotate theimpeller 142 can be relatively reduced. - Referring to
FIG. 5 , air and dust enters thecyclone inlet 162 and rotates inside thecyclone chamber 163 towards theside cover 170. The dust is separated from the air by centrifugal force and collected in thedust collecting chamber 164. The clean air exits thecyclone chamber 163 through theair discharge pipe 171 formed on theside cover 170 and reaches thefilter member 180 engaged with theside cover 170. The air is secondly filtered as it passes through thefilter member 180 so that any remaining dust is separated. The clean resultant air is then passed through theair passing hole 191 of thefilter supporting member 190 and discharged out of thedust separating unit 150. The air then passes through the passages such as theair discharge hole 111 a (seeFIG. 1 ) formed on a rear portion of theupper casing 111 and is discharged through thesuction port assembly 100. - Meanwhile, a user can observe the status of the
cyclone chamber 163 and thedust collecting chamber 164 disposed inside the cyclonedust separating unit 160 during cleaning process. If determining that thedust collecting chamber 164 needs emptying, the user separates thedust separating unit 150 from the dust separating unit chamber (S) (FIG. 1 ), removes the cyclonedust separating unit 160 and theside cover 170, and discards dust of thedust collecting chamber 164. The user may remove thefilter support member 190 together with thefilter member 180 from theside cover 170 to clean thefilter member 180. - While certain exemplary embodiments of the present disclosure have been shown and described with reference to certain preferred 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 and their equivalents.
