- a driving shaft 116 rotates in association with the rotation of a suction motor (not shown) which is built within the cleaner body 110
- the reference numeral 138 refers to a connection pipe for connecting a dirt suction hole (not shown) to the cleaner body 1 10 to allow air to flow therethrough.
- the cleaner body 110 has a plurality of locking recesses 240 formed in proximity to the suction port assembly 130 .
- a resilient pedal 150 having a locking protrusion 154 , is pivotably mounted on the suction port assembly 130 . Accordingly, when the cleaner body 110 rotates with respect to the suction port assembly 130 , the locking protrusion 154 is resiliently locked in one of the locking recesses 240 , thereby sequentially restricting the cleaner body 110 from rotating.
- the resilient pedal 150 includes a pedal body 151 and a resilient support portion 155 .
- the pedal body 151 includes the locking protrusion 154 protruding from a side thereof, a rotation shaft 152 formed through a center thereof, and a pedal portion 153 formed on an upper portion thereof.
- the pedal body 151 is pivotably mounted on the suction port assembly 130 in such a manner that the rotation shaft 151 is rotatably connected to a mounting portion 137 of the suction port assembly 130 .
- the pedal portion 153 is exposed in an upward direction from the suction port assembly 130 . Accordingly, a user presses a top of the pedal portion 153 to pivot the pedal body 150 during use of the upright type vacuum cleaner 200 .
- the resilient support portion 155 resiliently urges the pedal body 151 to pivot the pedal body 151 in a predetermined direction.
- the resilient pedal 150 is provided with a resilient support portion comprising a plate member 155 , which protrudes from a lower end of the pedal body 151 .
- the plate member 155 is integrally formed with the pedal body 151 and has a bending portion formed at a center thereof.
- the pedal body 151 is mounted on the mounting portion 137 such that an end of the plate member 155 is supported on an inner wall 137 a ( FIG. 2 ) of the mounting portion 137 .
- the pedal portion 153 pivots and thus the plate member 155 is deformed.
- the plate member 155 is subject to a recovering force.
- the pedal body 151 Being released from the external force, the plate member 155 has a tendency to recover its original shape due to the recovering force, and accordingly, the pedal body 151 is automatically returned to its initial position.
- the initial position of the pedal body 151 is a position where the locking protrusion 154 resiliently presses a side of the cleaner body 110 .
- the resilient pedal 150 is not limited to the described preferred embodiment. That is, various changes and modifications can be made if the resilient pedal 150 includes the pedal body 151 pivotably mounted on the suction port assembly 130 to pivot by a pressure of a user, and the resilient support portion 155 for resiliently pressing the pedal body 151 .

- the locking recesses 240 include an upright position recess 241 , an inclined position recess 242 , and a parallel position recess 243 , as shown in FIG. 4 .
- the upright position recess 241 on which the locking protrusion 154 is locked, allows the cleaner body 110 to maintain its upright position with respect to a surface to be cleaned. Accordingly, when the upright type vacuum cleaner 200 is not in use, generally with the cleaner body 110 being in the upright position with respect to the surface to be cleaned, the locking protrusion 154 is locked in the upright position recess 241 such that the cleaner body 110 is prevented from rotating regardless of an external force or of its own weight.
- the inclined position recess 242 restricts the cleaner body 110 from rotating beyond a predetermined angle between the cleaner body 110 and the suction port assembly 130 . That is, when the cleaner body 110 rotates at the predetermined angle with respect to the suction port assembly 130 , the locking protrusion 154 is locked in the inclined position recess 242 , thereby preventing the cleaner body 110 from further rotating beyond the predetermined angle. Accordingly, when there is a small obstacle such as a threshold ahead, the upright type vacuum cleaner 200 is easily lifted to avoid the obstacle during cleaning.
- the plural inclined position recesses 242 can be provided, if necessary.
- the parallel position recess 243 allows the cleaner body 110 to maintain its parallel position with respect to the surface to be cleaned.
- the plate member 155 is in relaxed state. Accordingly, even when the upright type vacuum cleaner 200 is used with the cleaner body 110 lying in a position parallel to the surface to be cleaned for a long time, permanent damage to plate member 155 is prevented.
- the parallel position recess 243 has a slanted surface 243 a formed on a side thereof, which facilitates the release of the locking protrusion 154 from the parallel position recess 243 thereby allowing the cleaner body 110 to be returned to a working position.
- the locking protrusion 154 can be easily released from the parallel position recess 243 with little or no force required on the pedal portion 153 because the slanted surface 243 a allows the locking protrusion 154 to slide out of the parallel position recess.
- the locking protrusion 154 presses against the side surface of the cleaner body 110 it can be moved along the slanted surface 243 a of the parallel position maintaining recess 243 . Moreover, since the plate element 155 is in a more relaxed state when the locking protrusion 154 is in the parallel position recess 243 , the load on the plate member 155 is decreased to some extent. Therefore, there is an effect of decreasing the resistance or friction generated when the locking protrusion 154 resiliently presses the side surface of the cleaner body 110 .
- the inclined position recess 242 also has a slanted surface 242 a to decrease the operation resist, which is generated when cleaner body 110 rotates.
- the locking protrusion 154 can be sequentially locked into one of the locking recesses 241 , 242 or 243 in a stepwise manner, as the cleaner body 110 rotates such that when the locking protrusion 154 engages one of the recesses the cleaner body 110 is prevented from rotating further toward the cleaning surface.
- the locking protrusion 154 has to be released from the locking recesses it is engaged with.
- a user presses the pedal portion 153 to cause the pedal portion 153 to pivot the resilient pedal 150 .
- the cleaner body 110 can rotate on the rotation shaft portion.
- resilient force provided by the resilient support portion 155 causes the resilient pedal 150 to automatically pivot back against the side of the cleaner body and which causes the locking protrusion 154 to contact with the cleaner body 110 .
- the locking protrusion 154 can then re-engage a locking recess.
- the upright-type vacuum cleaner further comprises a frame 262 having a duct 261 formed at a side of the cleaner body 110 in a lengthwise direction in order to communicate with the motor driving chamber 112 , a support member 263 protruding to a predetermined dimension from an inside wall of the duct 261 , and a filter 264 for insertion into the duct 261 .
- a filter cover 265 having a grill portion 265 a is disposed adjacent to the frame 262 for rotation to allow the frame 262 to be opened and closed, and a removal removal means 270 for opening and closing the filter cover 265 .
- the removal means 270 includes a hook 280 integrally formed at a front end of the filter cover 265 , and a locking hole 290 having a locking protrusion 290 a disposed at the frame 262 placed at a position generally corresponding to the position of the hook 280 .
- the hook 280 comprises a fixing portion 281 extended in an inner direction from the filter cover 265 , a flexible pressing portion 282 bent in a direction approximately 180° from the fixing portion 281 and extended outwardly from the filter cover 265 , and a pair of protrusions 283 disposed at both sides of the flexible pressing portion 282 for providing a connection to the locking protrusion 290 a of the locking hole 290 .
- the flexible pressing portion 282 is flexibly biased in a direction of opening of a free end in regard to the fixing portion 281 .
- the filter cover 265 will be inhibited from opening by the discharging pressure of the air while a user is using the vacuum cleaner, since the protrusion 283 of the hook 280 and the locking protrusion 290 a of the locking hole 290 are firmly engaged, when the discharging pressure of the air affects the filter cover 265 in the closing state of the filter cover 265 .
- the filter cover 265 is firmly held in the closed position when the hook 280 is inserted into the locking hole 290 of the frame 262 , and the protrusion 283 of the hook 280 is locked with the locking protrusion 290 a of the locking hole 290 .
- the filter cover 265 To open the filter cover 265 , the user slightly presses the flexible pressing portion 282 of the hook 280 , and the protrusion 53 of the hook 280 is released from engagement with the locking protrusion 290 a of the locking hole 290 . Thus, the filter cover 265 is easily opened.
- a cut away portion 284 can be formed in a bent portion of the fixing portion 281 of the hook 280 and the flexible pressing portion 282 in order to increase the elasticity of the flexible pressing portion 282 with respect to the fixing portion 281 .
- the preferred embodiment of the present invention has been described and illustrated having two hooks 280 and 280 ′ and two locking holes 290 and 290 ′, but one hook and one locking hole can also be used.
- the air discharged to the motor driving chamber 112 is blown into the duct 261 , and the air is again discharged to the outside through the filter 264 and the grill portion 265 a of the filter cover 265 .
- the dust and dirt included in the air is filtered at the filter 264 .
- the filter cover 265 is opened from the frame 262 for cleaning or changing of the filter 264 after the vacuum cleaner is used a long time, the user just presses the flexible pressing portion 282 of the hook 280 disposed at the filter cover 265 .
- the protrusion 283 disposed at the flexible pressing portion 282 is flexibly engaged with the locking protrusions 290 a of the locking hole 290 disposed at the frame 262 when the filter cover 265 is closed, thus the filter cover 265 is not easily opened since the filter cover 265 is not affected by the discharging pressure of the air.
- the filter cover 265 can be easily opened as the protrusion 283 of the hook 280 is released from the flexible engagement with the locking protrusion 290 a of the locking hole 290 . In other words, great force is not required to pull the filter cover 265 , in order to open the filter cover 265 , unlike with the conventional upright vacuum cleaner.
- the closed state of the filter cover 265 is maintained, since the hook 280 of the filter cover 265 is inserted into the locking hole 290 of the frame 262 , and the protrusion 283 of the hook 280 is flexibly locked with the locking protrusion 290 a of the locking hole 290 .
- the resilient support portion 155 is in relaxed state even when the cleaner body 110 is in a parallel position with respect to the surface to be cleaned, since the locking protrusion 154 is locked in the parallel position recess 243 which is formed on the side surface of the cleaner body 110 .
- the resilient support portion 155 is in relaxed state even when the cleaner body 110 is in parallel to the surface to be cleaned for a long time, and as a result, the resilient support portion 155 is prevented from being deformed permanently.
- the resilient support portion 155 is subject to a lesser load due to the presence of the slanted surface 243 a formed on the parallel position recess 243 . Therefore, there is an effect of decreasing the operation resist of the rotating operation of the cleaner body 110 .
- the closed state of the filter cover is maintained since the protrusion of the flexible pressing portion disposed at the hook of the filter cover is flexibly connected to and in engagement with the locking protrusion of the locking hole disposed at the frame, thus the filter cover is not easily opened by the discharging pressure of the air.
- the opening and the closing of the filter cover is easily operated, as the filter cover is opened by releasing the locking state of the protrusion of the flexible pressing portion and the locking protrusion of the locking hole, with the simple method of pressing the flexible pressing portion of the hook.
- the opening and the closing of the filter cover is very easy, while the filter cover cannot be unintentionally opened by the force of the discharged air while the user is using the vacuum cleaner. Therefore, the convenience of the vacuum cleaner will be improved.

Description
- BACKGROUND OF THE INVENTION
- 1. Field of the Invention
- The present invention relates generally to a vacuum cleaner, and more particularly to an upright type vacuum cleaner comprising a cleaner body and a suction port assembly that are connected to each other and can rotate freely with respect to each other.
- 2. Description of the Related Art
- As shown in
FIGS. 1 and 2 , a general uprighttype vacuum cleaner 100 comprises acleaner body 110 and asuction port assembly 130. Thesuction port assembly 130 has a dust suction hole (not shown) formed in the underside thereof, which is connected with thecleaner body 110 through an air passage, part of which includesconnection pipe 138. Thecleaner body 110 comprises arotation shaft portion 115 protruding from two lower opposing sides of thecleaner body 110 and thesuction port assembly 130 comprises two oppositely disposedrotation shaft holes 136, each of which is completely formed with amounting cover 135 being mounted over therotation shaft hole 136 to form a retainer for one each of the two ends of herotation shaft portion 115. Thecleaner body 110 and thesuction port assembly 130 are connected to each other as therotation shaft portion 115 is inserted into therotation shaft hole 136, allowing thecleaner body 110 and thesuction port assembly 130 to rotate freely with respect to each other. According to the uprighttype vacuum cleaner 100, a user can perform cleaning operations by varying the angle between the surface to be cleaned and thecleaner body 110 depending on the different cleaning surfaces. - The
cleaner body 110 has one ormore locking recesses 140 formed in a side thereof. Thesuction port assembly 130 is provided with amounting portion 137 and aresilient pedal 150 that is pivotably mounted on themounting portion 137. Theresilient pedal 150 has alocking protrusion 154 protruding from a side thereof. Thelocking protrusion 154 is sequentially locked in the one ormore locking recess 140 when thecleaner body 110 rotates relative to thesuction port assembly 130. - The
resilient pedal 150 also has aresilient support portion 155 in the shape of a plate that is formed integrally with a lower end of theresilient pedal 150. Theresilient pedal 150 is mounted on themounting portion 137 such that an end of theresilient support portion 155 is supported on aninner wall 137 a of themounting portion 137. Accordingly, thelocking protrusion 154 resiliently presses a side surface of thecleaner body 110 and then is sequentially locked in the one ormore locking recesses 140 when thecleaner body 110 rotates. In order for thecleaner body 110 to be released from the locking state in which thelocking protrusion 154 is locked in the one ormore locking recesses 140 and to once again be free to rotate, aresilient pedal portion 153 is pressed to pivot theresilient pedal 150, releasing thelocking protrusion 154 from the one ormore locking recesses 140. - The one or
more locking recesses 140 preferably include an upright position recess 141 and an inclined position recess 142, which are formed along a portion to which thelocking protrusion 154 contacts when thecleaner body 110 rotates. When thecleaner body 110 is in an upright position, thelocking protrusion 154 is locked in the upright position recess 141. Accordingly, thecleaner body 110 does not rotate but is held in the upright portion when the uprighttype vacuum cleaner 100 is not in use. When the uprighttype vacuum cleaner 100 is in use, with thecleaner body 110 being rotated at a predetermined angle with respect to a surface to be cleaned, thelocking protrusion 154 is locked in one of the inclined position recesses 142. Accordingly, when thevacuum cleaner 100 is lifted up over an obstacle such as a threshold during cleaning, thesuction port assembly 130 rotates no more than the predetermined angle with respect to thecleaner body 110. - When in use, the
cleaner body 110 of the uprighttype vacuum cleaner 100 can lie parallel or nearly parallel to the surface to be cleaned, as shown inFIG. 3 . When used in this position, thelocking protrusion 154 is pressed to the side surface of thecleaner body 110 such that theresilient support portion 155 remains subject to an external force that tends to deform the resilient support portion 155 (FIGS. 1 and 2 ). If the upright type vacuum clear 100 is used in this way for a long time, theresilient support portion 155 can become deformed. When theresilient support portion 155 deforms, it provides a reduced engagement force to thelocking protrusion 154. - In addition, as described above, when the
cleaner body 110 is used lying in parallel to the surface to be cleaned, thelocking protrusion 154 presses against the side surface of thecleaner body 110. When thecleaner body 110 rotates about therotation shaft portion 115, there is a contact resistance or friction generated where the surfaces of thelocking protrusion 154 and the side surface of thecleaner body 110 make contact with each other. Because of this resistance, the cleaner body does not rotate smoothly. - The present invention has been developed to solve the above-described problems. Accordingly, it is an object of the present invention to provide an upright type vacuum cleaner improved in construction so that it becomes capable of preventing deformation of a resilient pedal and reducing any rotation resist of the cleaner body.

FIG. 7 is an enlarged detail view showing an important part ofFIG. 6 in greater detail; and -
FIG. 8 is a sectional view taken approximately along a line VI-VI ofFIG. 6 . - Hereinafter, a preferred embodiment of the present invention will be described in greater detail with reference to the accompanying drawings. With respect to those components having constructions and functions similar to those of the conventional upright type vacuum cleaner described with reference to
FIGS. 1 through 3 , identical reference numerals are assigned. Therefore, a detailed description of like numbered parts will be omitted. - Referring now to
FIGS. 4 and 5 , an uprighttype vacuum cleaner 200 according to the present invention includes acleaner body 110 and asuction port assembly 130 rotatably connected to thecleaner body 110. Adriving shaft 116 rotates in association with the rotation of a suction motor (not shown) which is built within thecleaner body 110, and thereference numeral 138 refers to a connection pipe for connecting a dirt suction hole (not shown) to the cleaner body 1 10 to allow air to flow therethrough. - The
cleaner body 110 has a plurality oflocking recesses 240 formed in proximity to thesuction port assembly 130. Aresilient pedal 150, having alocking protrusion 154, is pivotably mounted on thesuction port assembly 130. Accordingly, when thecleaner body 110 rotates with respect to thesuction port assembly 130, thelocking protrusion 154 is resiliently locked in one of thelocking recesses 240, thereby sequentially restricting thecleaner body 110 from rotating. - The
resilient pedal 150 includes apedal body 151 and aresilient support portion 155. Thepedal body 151 includes thelocking protrusion 154 protruding from a side thereof, arotation shaft 152 formed through a center thereof, and apedal portion 153 formed on an upper portion thereof. Thepedal body 151 is pivotably mounted on thesuction port assembly 130 in such a manner that therotation shaft 151 is rotatably connected to amounting portion 137 of thesuction port assembly 130. At this point, thepedal portion 153 is exposed in an upward direction from thesuction port assembly 130. Accordingly, a user presses a top of thepedal portion 153 to pivot thepedal body 150 during use of the uprighttype vacuum cleaner 200. - The
resilient support portion 155 resiliently urges thepedal body 151 to pivot thepedal body 151 in a predetermined direction. In this embodiment, theresilient pedal 150 is provided with a resilient support portion comprising aplate member 155, which protrudes from a lower end of thepedal body 151. Theplate member 155 is integrally formed with thepedal body 151 and has a bending portion formed at a center thereof. - As described above with reference to
FIG. 2 , thepedal body 151 is mounted on the mountingportion 137 such that an end of theplate member 155 is supported on aninner wall 137 a (FIG. 2 ) of the mountingportion 137. When thepedal portion 153 is subject to an external force, thepedal body 151 pivots and thus theplate member 155 is deformed. As a result of its resilient characteristics, theplate member 155 is subject to a recovering force. Being released from the external force, theplate member 155 has a tendency to recover its original shape due to the recovering force, and accordingly, thepedal body 151 is automatically returned to its initial position. The initial position of thepedal body 151 is a position where the lockingprotrusion 154 resiliently presses a side of thecleaner body 110. - Meanwhile, the
resilient pedal 150 is not limited to the described preferred embodiment. That is, various changes and modifications can be made if theresilient pedal 150 includes thepedal body 151 pivotably mounted on thesuction port assembly 130 to pivot by a pressure of a user, and theresilient support portion 155 for resiliently pressing thepedal body 151. - A lower side of the
cleaner body 110, which contacts with the lockingprotrusion 154 of theresilient pedal 150 when thecleaner body 110 rotates, has a partially concave configuration to form the plurality of the locking recesses 240. The locking recesses 240 include anupright position recess 241, aninclined position recess 242, and aparallel position recess 243, as shown inFIG. 4 . - The
upright position recess 241, on which the lockingprotrusion 154 is locked, allows thecleaner body 110 to maintain its upright position with respect to a surface to be cleaned. Accordingly, when the uprighttype vacuum cleaner 200 is not in use, generally with thecleaner body 110 being in the upright position with respect to the surface to be cleaned, the lockingprotrusion 154 is locked in theupright position recess 241 such that thecleaner body 110 is prevented from rotating regardless of an external force or of its own weight. - The
inclined position recess 242 restricts thecleaner body 110 from rotating beyond a predetermined angle between thecleaner body 110 and thesuction port assembly 130. That is, when thecleaner body 110 rotates at the predetermined angle with respect to thesuction port assembly 130, the lockingprotrusion 154 is locked in theinclined position recess 242, thereby preventing thecleaner body 110 from further rotating beyond the predetermined angle. Accordingly, when there is a small obstacle such as a threshold ahead, the uprighttype vacuum cleaner 200 is easily lifted to avoid the obstacle during cleaning. The plural inclined position recesses 242 can be provided, if necessary. - The
parallel position recess 243, on which the lockingprotrusion 154 may be locked, allows thecleaner body 110 to maintain its parallel position with respect to the surface to be cleaned. When thecleaner body 110 lies in a position parallel to the surface to be cleaned, theplate member 155 is in relaxed state. Accordingly, even when the uprighttype vacuum cleaner 200 is used with thecleaner body 110 lying in a position parallel to the surface to be cleaned for a long time, permanent damage toplate member 155 is prevented. - The
parallel position recess 243 has a slantedsurface 243 a formed on a side thereof, which facilitates the release of the lockingprotrusion 154 from theparallel position recess 243 thereby allowing thecleaner body 110 to be returned to a working position. When thecleaner body 110 is in an upright position, and when the lockingprotrusion 154 is engaged in theparallel position recess 243, the lockingprotrusion 154 can be easily released from theparallel position recess 243 with little or no force required on thepedal portion 153 because theslanted surface 243 a allows the lockingprotrusion 154 to slide out of the parallel position recess. Accordingly, as the lockingprotrusion 154 presses against the side surface of thecleaner body 110 it can be moved along the slantedsurface 243 a of the parallelposition maintaining recess 243. Moreover, since theplate element 155 is in a more relaxed state when the lockingprotrusion 154 is in theparallel position recess 243, the load on theplate member 155 is decreased to some extent. Therefore, there is an effect of decreasing the resistance or friction generated when the lockingprotrusion 154 resiliently presses the side surface of thecleaner body 110. In a preferred embodiment, theinclined position recess 242 also has a slantedsurface 242 a to decrease the operation resist, which is generated whencleaner body 110 rotates. - According to the upright
type vacuum cleaner 200 described above, the lockingprotrusion 154 can be sequentially locked into one of the locking recesses 241, 242 or 243 in a stepwise manner, as thecleaner body 110 rotates such that when the lockingprotrusion 154 engages one of the recesses thecleaner body 110 is prevented from rotating further toward the cleaning surface. For a further rotation of thecleaner body 110 toward the cleaning surface, the lockingprotrusion 154 has to be released from the locking recesses it is engaged with. In order for the lockingprotrusion 154 to be released from the locking recesses 241, 242, 243, a user presses thepedal portion 153 to cause thepedal portion 153 to pivot theresilient pedal 150. After the lockingprotrusion 154 is moved away from alocking recess cleaner body 110 can rotate on the rotation shaft portion. When pressure on thepedal portion 153 is released, resilient force provided by theresilient support portion 155 causes theresilient pedal 150 to automatically pivot back against the side of the cleaner body and which causes the lockingprotrusion 154 to contact with thecleaner body 110. The lockingprotrusion 154 can then re-engage a locking recess. - As shown in
FIGS. 6 through 8 , the upright-type vacuum cleaner further comprises aframe 262 having aduct 261 formed at a side of thecleaner body 110 in a lengthwise direction in order to communicate with themotor driving chamber 112, asupport member 263 protruding to a predetermined dimension from an inside wall of theduct 261, and afilter 264 for insertion into theduct 261. Afilter cover 265 having agrill portion 265 a is disposed adjacent to theframe 262 for rotation to allow theframe 262 to be opened and closed, and a removal removal means 270 for opening and closing thefilter cover 265. - The removal means 270 includes a
hook 280 integrally formed at a front end of thefilter cover 265, and alocking hole 290 having a lockingprotrusion 290 a disposed at theframe 262 placed at a position generally corresponding to the position of thehook 280. - The
hook 280 comprises a fixingportion 281 extended in an inner direction from thefilter cover 265, a flexiblepressing portion 282 bent in a direction approximately 180° from the fixingportion 281 and extended outwardly from thefilter cover 265, and a pair ofprotrusions 283 disposed at both sides of the flexiblepressing portion 282 for providing a connection to the lockingprotrusion 290 a of thelocking hole 290. - The flexible
pressing portion 282 is flexibly biased in a direction of opening of a free end in regard to the fixingportion 281. Thus, thefilter cover 265 will be inhibited from opening by the discharging pressure of the air while a user is using the vacuum cleaner, since theprotrusion 283 of thehook 280 and the lockingprotrusion 290 a of thelocking hole 290 are firmly engaged, when the discharging pressure of the air affects thefilter cover 265 in the closing state of thefilter cover 265. In other words, thefilter cover 265 is firmly held in the closed position when thehook 280 is inserted into thelocking hole 290 of theframe 262, and theprotrusion 283 of thehook 280 is locked with the lockingprotrusion 290 a of thelocking hole 290. - To open the
filter cover 265, the user slightly presses the flexiblepressing portion 282 of thehook 280, and the protrusion 53 of thehook 280 is released from engagement with the lockingprotrusion 290 a of thelocking hole 290. Thus, thefilter cover 265 is easily opened. - On the other hand, a cut away
portion 284 can be formed in a bent portion of the fixingportion 281 of thehook 280 and the flexiblepressing portion 282 in order to increase the elasticity of the flexiblepressing portion 282 with respect to the fixingportion 281. Moreover, the preferred embodiment of the present invention has been described and illustrated having twohooks holes - In the upright-type vacuum cleaner according to the preferred embodiment of the present invention having the above elements, the air discharged to the
motor driving chamber 112 is blown into theduct 261, and the air is again discharged to the outside through thefilter 264 and thegrill portion 265 a of thefilter cover 265. At this time, the dust and dirt included in the air is filtered at thefilter 264. When thefilter cover 265 is opened from theframe 262 for cleaning or changing of thefilter 264 after the vacuum cleaner is used a long time, the user just presses the flexiblepressing portion 282 of thehook 280 disposed at thefilter cover 265. Theprotrusion 283 disposed at the flexiblepressing portion 282 is flexibly engaged with the lockingprotrusions 290 a of thelocking hole 290 disposed at theframe 262 when thefilter cover 265 is closed, thus thefilter cover 265 is not easily opened since thefilter cover 265 is not affected by the discharging pressure of the air. When the flexiblepressing portion 282 is pressed in the closed state of thefilter cover 265, thefilter cover 265 can be easily opened as theprotrusion 283 of thehook 280 is released from the flexible engagement with the lockingprotrusion 290 a of thelocking hole 290. In other words, great force is not required to pull thefilter cover 265, in order to open thefilter cover 265, unlike with the conventional upright vacuum cleaner. - As described so far, when the user pushes the
filter cover 265 to close thefilter cover 265 after cleaning and changing thefilter 264 in the opened state of thefilter cover 265, the closed state of thefilter cover 265 is maintained, since thehook 280 of thefilter cover 265 is inserted into thelocking hole 290 of theframe 262, and theprotrusion 283 of thehook 280 is flexibly locked with the lockingprotrusion 290 a of thelocking hole 290. - According to the present invention as described above, the
resilient support portion 155 is in relaxed state even when thecleaner body 110 is in a parallel position with respect to the surface to be cleaned, since the lockingprotrusion 154 is locked in theparallel position recess 243 which is formed on the side surface of thecleaner body 110. - Accordingly, the
resilient support portion 155 is in relaxed state even when thecleaner body 110 is in parallel to the surface to be cleaned for a long time, and as a result, theresilient support portion 155 is prevented from being deformed permanently. - Also, when the
cleaner body 110 rotates and the lockingprotrusion 154 moves in proximity to theparallel position recess 243, theresilient support portion 155 is subject to a lesser load due to the presence of the slantedsurface 243 a formed on theparallel position recess 243. Therefore, there is an effect of decreasing the operation resist of the rotating operation of thecleaner body 110. - According to the above-described present invention, the closed state of the filter cover is maintained since the protrusion of the flexible pressing portion disposed at the hook of the filter cover is flexibly connected to and in engagement with the locking protrusion of the locking hole disposed at the frame, thus the filter cover is not easily opened by the discharging pressure of the air. In addition, the opening and the closing of the filter cover is easily operated, as the filter cover is opened by releasing the locking state of the protrusion of the flexible pressing portion and the locking protrusion of the locking hole, with the simple method of pressing the flexible pressing portion of the hook. In other words, according to the present invention, the opening and the closing of the filter cover is very easy, while the filter cover cannot be unintentionally opened by the force of the discharged air while the user is using the vacuum cleaner. Therefore, the convenience of the vacuum cleaner will be improved.
- Although preferred embodiments of the present invention have been described, it is understood that the present invention should not be limited to these preferred embodiments but various changes and modifications can be made by one skilled in the art within the spirit and scope of the present invention as hereinafter claimed.
