DETAILED DESCRIPTION
Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.
Hereinafter, a vacuum cleaner having a shredder according to first to third exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawing figures.
Referring to FIG. 1, a vacuum cleaner 1 according to a first exemplary embodiment of the present disclosure includes a cleaner body 10, a suction nozzle assembly 31, a dust bin 50 and a shredder 70.
Referring to FIG. 1, the cleaner body 10 has main wheels 11a and a subsidiary wheel (not illustrated) disposed on both sides and a front of a bottom surface thereof, respectively, to smoothly move along a surface to be cleaned in a vacuum cleaning.
In addition, the cleaner body 10 has a cyclone unit 13 for separating a dust or dirt D drawn in along with an air from the surface to be cleaned and a suction motor 15 which corresponds to a suction source, contained therein.
In this case, to guide the air laden with the dust D drawn in into the cleaner body 10 to the cyclone unit 13, the cleaner body 10 is provided with a first air passage P1, which connects between a suction port 10a installed on a front end thereof and an air inlet 13a of the cyclone unit 13. Further, to guide the air from which the dust D is separated at the cyclone unit 13 to the suction motor 15, the cleaner body 10 is provided with a second air passage P2, which connects between an air outlet 13b of the cyclone unit 13 and an inlet 15a of the suction motor 15.
Referring to FIG. 1, the suction nozzle assembly 31 has an intake port 31a formed on a bottom surface thereof facing the surface to be cleaned, and is coupled to and communicated with one end of an extended tube 33 having a telescopic structure to be contractible and extractable. The extended tube 33 and an extension hose 37 are communicated with each other through a handle 35. In this case, the handle 35 has a slide button 35a for turning on/off the suction motor 15 and adjusting an intensity of the suction force installed on one surface thereof. The extension hose 37, the one end of which is communicated with the handle 35, has the other end communicated with the suction port 10a of the cleaner body 10.
According to this, the air laden with the dust D drawn in into the intake port 31a of the suction nozzle assembly 31 successively passes through the extended tube 33, the inside of the handle 35 and the extension hose 37 and then flows into the first air passage P1 in the cleaner body 10.
Referring to FIG. 2, the dust bin 50 is detachably coupled into an accommodating recess 17 formed on the cleaner body 10. In this case, on a side surface of the accommodating recess 17 is installed a dust discharging port 13c for discharging the dust D from the cyclone unit 13. The dust discharging port 13c at one end thereof is communicated with a lower side of the cyclone unit 13, and at the other end thereof is communicated with a dust inlet 50a formed on one surface of the dust bin 50 when the dust bin 50 is mounted in the accommodating recess 17 of the cleaner body 10.
Referring to FIG. 3, the dust bin 50 is formed in a rectangular tub form having an opening 51 formed at an upper part thereof. The dust bin 50 at one surface thereof has an inserting hole 53 formed, so that a blocking plate 55 is slidably inserted thereinto.
In addition, to collect shredded paper 3 (see FIG. 1) supplied from the shredder 70 installed in the opening 51, the dust bin 50 is maintained in such a state that it is communicated with a lower part of the shredder 70. In this case, since the shredder 70 at the paper slot 71a for inserting a paper 3 is always opened, the dust bin 50 at the inside thereof is maintained at an atmospheric pressure. Like this, if the dust bin 50 at the inside thereof is in a state of such an atmospheric pressure, there is a problem in that during the vacuum cleaning, the vacuum cleaner at the air path from the suction nozzle assembly 31 to the suction motor 15 is not maintained well in a vacuum state. To address the problem, the dust bin 50 has an open and close part 54, which closes up the opening 51 thereof during the vacuum cleaning and opens the opening 51 thereof during the use of the shredder 70.
The open and close part 54 includes a blocking plate 55 capable of being led in into and withdrawn from the inserting hole 53 of the dust bin 50, and a pair of guide ribs 56 coupled with the blocking plate 55 to be capable of maintaining a sealing therebetween.
The blocking plate 55 is contoured corresponding to a shape of the dust bin 50, and to allow a user to easily lead in and withdraw the blocking plate 55, has one side end 55a projected to the outside of the dust bin 50 and bent downward.
The pair of guide ribs 56 are continuously formed in a parallel spaced-apart relation to each other along an inner surface of the dust bin 50 to form a coupling groove 56a. In this case, the coupling groove 56a is formed to have a width or height equal to or smaller than a thickness of the blocking plate 55, so that an end of the blocking plate 55 is tightly coupled thereto.
At this time, it is desirable that to increase a sealing performance between the blocking plate 55 and the guide ribs 56, a seal member (not shown) is disposed along the coupling groove 56a, and a seal member (not shown) is also disposed on an inner side of the inserting hole 53 of the dust bin 50 through which the blocking plate 55 passes.
Of course, instead of the open and close part 54, the dust bin 50 may have a valve type open and close part 155 as shown in FIGS. 4 to 6.
Referring to FIG. 5, the open and close part is provided with a valve 155, which is rotatably and pivotally disposed on a hinge axis H in the dust bin 50. In this case, to open and close up the opening 51 of the dust bin 50, the valve 155 has a pair of wings 156a and 156b symmetrically formed to a center of rotation thereof at both sides thereof. At this time, the pair of wings 156a and 156b at ends thereof come in contact with the inner surface of the dust bin 50, and by disposing seal members 157a and 157b along the ends of the pair of wings 156a and 156b, a sealing performance during the closing up of the opening 51 of the dust bin 50 can be improved.
Referring to FIG. 6, the open and close part includes a rotary knob 158, which is exposed to the outside of the dust bin 50 to allow the user to rotate the valve 155, The rotary knob 158 is connected to the hinge axis H, so that it can rotate the valve 155 in one direction and the other direction to open and close up the opening 51 of the dust bin 50.
In this case, to maintain the valve 155 in a closed-up state, a locking protrusion 158a for locking the rotary knob 158 is formed on an outer circumferential surface of the rotary knob 158, and a pair of fixing protrusions 159a and 159b to which the locking protrusion 158a is snapped are formed on an outer side surface of the dust bin 50.
The pair of fixing protrusions 159a and 159b are located at positions corresponding to angles of the pair of the wings 156a and 156b where they close up the opening 51 of the dust bin 50. In this case, the pair of fixing protrusions 159a and 159b are formed in a spaced-apart relation to each other to form a locking groove 159c into which the locking protrusion 158a is locked.
The shredder 70, which is for shredding the paper, such as receipts or the like, is installed to be communicated with the opening 51 formed on the upper part of the dust bin 50. In this case, as the shredder 70 is installed on the dust bin 50, shredded paper is naturally collected into the dust bin 50 by its own weight.
The shredder 70 as describe above may be configured in a manual type or an automatic type. First, an example of the shredder 70 configured in the manual type will be explained.
Referring to FIGS. 2 and 5, the shredder 70 includes a housing 71, a pair of rotary cutters 75a and 75b, and a rotary handle 77.
The housing 71 has a paper slot 71a formed at an upper surface thereof to insert the paper thereinto, and at a lower part thereof is opened to allow the shredded paper to fall down into the dust bin 50. In this case, it is desirable that at coupled portions (a lower end of the housing 71 and an upper end of the opening 51 of the dust bin 50) between the housing 71 and the dust bin 50, a seal member (not shown) is disposed to maintain a sealing therebetween.
Further, the housing 71 has guide protrusions 73 formed to be extended along a lower end of the paper slot 71a. The guide protrusions 73 guides to move a front end of the paper 3 inserted through the paper slot 71a to portions of the pair of the rotary cutters 75a and 75b, which are engaged with each other.
The pair of the rotary cutters 75a and 75b are rotatably installed in the housing 71, and have blade parts 176a and 176b (see FIG. 8) formed in a circumferential direction in a spaced-apart relation to each other on circumferential surfaces thereof to shred the paper 3 inserted into the housing 71 through the paper slot 71a. In this case, the pair of the rotary cutters 75a and 75b are disposed to be engaged in a parallel state with each other (to be specific, to alternately cross blade parts 176a and 176b thereof to each other). Accordingly, the paper, which passes through the pair of the rotary cutters 75a and 75b, is shredded into a plurality of paper strips with thin width.
Also, it is desirable that the pair of the rotary cutters 75a and 75b have gears (not shown) installed to engaged with each other on one ends of rotation axes A1 and A2 thereof, so that when one thereof is rotated in a forward direction, the other thereof is rotated in a reverse direction.
The rotary handle 77 is connected to the rotation axis A1 of any one 75a of the pair of rotary cutters 75a and 75b. In this case, the rotary handle 77 is exposed to the outside of the housing 71, so that it can be manipulated by the user.
A method of using the shredder 70 as constructed above is as follows. First, before the shredder 70 is used, the opening 51 of the dust bin 50 is opened by the open and close part 54 or 155. After that, a user inserts into the paper slot 71a with one hand and at the same time, rotates the rotary handle 77 with the other hand. As a result, the paper can be shredded.
Referring to FIG. 7, a dust bin 150 may be configured to have a partition plate 151, which divides it into a first chamber C1 for collecting the shredded paper discharged form shredder 70 and a second chamber C2 for collecting the dust discharged from the cyclone unit 13. In this case, the shredded paper and the dust collected in the first and the second chambers C1 and C2 are discharged through first and second outlets 152a and 152b on the lower part of the dust bin 150.
The first and second outlets 152a and 152b are simultaneously opened and closed up by a discharge cover 153. In this case, the discharge cover 153 has first to third coupling protrusions 153a, 153b and 153c formed to be detachably connected to the first and the second outlets 152a and 152b. At this time, a seal member (not shown) may be disposed on outer sides of the first and the second coupling protrusions 153a and 153b to maintain a sealing performance to the second chamber C2.
If the dust bin 150, the inside of which is divided by the partition plate 151, is applied, the open and close part 54 or 155 may be omitted because the second chamber C2 is maintained in a closed-up state by the discharge cover 153.
Referring to FIG. 8, the present disclosure, of course, may employ an automatic type shredder 170 besides the manual type shredder 70 as described above.
Like the manual type shredder 70, the automatic type shredder 170 includes a housing 171, a paper slot 171a, guide protrusions (not shown) and a pair of rotary cutters 175a and 175b. 
Also, the shredder 170 further includes a motor 178 connected to the rotation axis A1 of the rotary cutter 175a to rotate any one of the pair of rotary cutters 175a and 175b, and an operation button 179 for turning on and off the motor 178. In this case, the operation button 179 is electrically connected to a circuit part (not shown) for applying an electric power to the motor 178, and is disposed in a certain position on the outer side of the housing 171, so that it can be manipulated by the user.
A method of using the shredder 170 as constructed above is as follows. First, the opening 51 of the dust bin 50 is opened by the open and close part 54 or 155. And then, in a state where the operation button 179 is pushed by a user to turn on the motor 178, a paper is inserted into the paper slot 71a by one hand of user. As a result, the paper is shredded through the rotary cutters 175 and 175b rotated by the motor 178 and then collected into the dust bin 50.
In this case, according to designs of the circuit part, the shredder 170, of course, may be configured to be operated in such a semi-automatic manner that the rotary cutters 175a and 175b are driven only in a state where the operation button 179 are pushing by the user.
A construction of ah upright type vacuum cleaner 1a in which a shredder 270 is installed, according to a second exemplary embodiment of the present disclosure will be explained with reference to FIGS. 9 and 10.
Like the canister type vacuum cleaner 1 as described above, the upright type vacuum cleaner 1a has a cyclone unit and a suction motor contained in a cleaner body 210. In the upright type vacuum cleaner 1a according to the second exemplary embodiment of the present disclosure, however, a dust bin 250 and a shredder 270 are mounted in the cleaner body 210, so that they are not completely exposed to the outside of the cleaner body 210, but only a portion thereof is exposed to the outside of the cleaner body 210, unlike the canister type vacuum cleaner 1.
It is desirable that in view of the fact that only the portion of the dust bin 250 is exposed, an open and close part 254, which opens and closes up an opening of a dust bin 250 by using a blocking plate 255 and guide ribs 256, is applied.
Further, it is desirable that the shredder 270 is formed in the same construction as that of the automatic type shredder 170 rather than the manual type shredder 70. However, in view of the fact that a housing 271 of the shredder 270 at a front hereof is exposed, a paper slot 271a and an operation button 279 are formed in the front of the housing 271 as shown in FIG. 9 and guide protrusions 273 are disposed to guide the paper from the paper slot 271a to portions of a pair of rotary cutters 275a and 275b, which are engaged with each other.
In FIG. 9, non-explained numerals 211, 231, 235 and 259 designate wheels installed at both sides of a cleaner body 210, a suction nozzle assembly hinged and connected to a lower end of the cleaner body 210 to be able to communicated therewith, a handle for moving the cleaner body 210, and a withdrawal handle for withdrawing the dust bin 250 from the cleaner body 210, respectively.
A construction of a robot cleaner 1b in which a shredder 370 is installed, according to a third exemplary embodiment of the present disclosure will be explained with reference to FIG. 11.
The robot cleaner 1b according to the third exemplary embodiment of the present disclosure is configured, so that an intake port 311 facing the surface to be cleaned, is formed on a bottom surface of a cleaner body 310, and a suction source for drawing in the dust or dirt, for example, an impeller 379 and a driving motor 378, are disposed on a suction air path P (that is, P3, P4, and P5) from the intake port 311 to a dust bin 350.
The impeller 379 is rotated receiving a rotation force from the driving motor 378, and is disposed between the intake port 311 and the dust bin 350. Like this, if the impeller 379 is used, a portion from the intake port 311 to a chamber 313 in which the impeller 379 is installed among the suction path P is maintained in a vacuum state.
Accordingly, since in the robot cleaner 1b according to the third exemplary embodiment of the present disclosure, the dust bin 350 is installed in the rear of the impeller 379, it functions even if the dust bin 350 at the inside thereof is not maintained in a vacuum state. Thus, in the dust bin 350, the open and close part 54, 155 or 254 of as explained in the vacuum cleaners of the first and the second exemplary embodiment of the present disclosure can be omitted.
The shredder 370 applied to the robot cleaner 1b according to the third exemplary embodiment of the present disclosure may employ the manual type shredder 70 (see FIG. 5) as described above, but it preferably employs the automatic type shredder 170 (see FIG. 7) as described above to allow a portion of the shredder 370 to be embedded in the cleaner body 310, thereby compactly maintaining the robot cleaner 1b in entire size.
In FIG. 11, non-explained numerals 351, 353, 371, 371a, 373, 375a and 375b, 379, and D designate an opening of the dust bin, a dust inlet for taking a dust or dirt into the dust bin 350 through a suction air passage P5, a housing, a paper slot, guide protrusions, rotary cutters, an operation button, and a dust or dirt, respectively.
As described above, according to the first to third exemplary embodiments of the present disclosure, the canister type vacuum cleaner, the upright type vacuum cleaner, and the robot cleaner combine the shredding function capable of shredding documents (bills, receipts, postal matters, etc.) with personal information with the cleaning function by installing the shredders 70, 170, 270 and 370 therein, respectively, thereby thoroughly preventing unwanted leaks of the personal information and improving the convenience in use.
Although representative embodiments of the present disclosure have been shown and described in order to exemplify the principle of the present disclosure, the present disclosure is not limited to the specific embodiments. It will be understood that various modifications and changes can be made by one skilled in the art without departing from the spirit and scope of the disclosure as defined by the appended claims. Therefore, it shall be considered that such modifications, changes and equivalents thereof are all included within the scope of the present disclosure.
