Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner that maximizes the dust collection capacity and allows the collected dust to be easily discharged.

  In general, a vacuum cleaner is a device that filters dust in a dust separator after sucking in air containing dust using a suction input generated by a motor mounted inside a main body.

  Such a vacuum cleaner can be classified into a canister type in which a suction nozzle as a suction port is provided separately from the main body and connected by a connecting pipe, and an upright type in which the suction nozzle is integrally formed.

  On the other hand, the dust collection unit attached to the cyclone vacuum cleaner uses the cyclone principle so that the dust contained in the inhaled air is separated from the air and collected, and the dust is removed. The air is a device that is exhausted to the outside of the vacuum cleaner.

  In order to improve the dust collection performance, recently, a multi-cyclone dust collection unit provided with a cyclone unit composed of a plurality of orders is used.

  Specifically, the multi-cyclone dust collecting unit includes a dust collector, a primary cyclone unit that separates relatively large dust from the air sucked into the dust collector, and dust separated by the primary cyclone unit. A secondary cyclone unit is provided for separating the fine dust again when the air is introduced.

  Further, the dust separated by the first cyclone unit and the second cyclone unit is collected by a first dust collecting unit and a second dust collecting unit formed inside the dust collector, respectively. . That is, the conventional dust collection unit is configured to include both the primary cyclone unit and the secondary cyclone unit.

  In addition, such a dust collection unit is detachably attached to the vacuum cleaner in order to discharge the dust collected inside.

  By the way, according to the conventional dust collecting unit, the first cyclone unit and the second cyclone unit are provided in the dust collecting unit, so that the first dust collecting unit is structurally formed to be small. There is a problem that the dust collection capacity of the dust collecting portion is small, which causes a disadvantage that the user needs to frequently remove the dust.

  In addition, since the primary cyclone unit and the secondary cyclone unit are both provided in the dust collection unit, the weight of the dust collection unit becomes considerable, and the user attaches or removes the dust collection unit to the vacuum cleaner, There arises a problem that a considerable force is required to remove dust.

  Further, conventionally, in order to remove dust collected in the dust collection unit, in the process of separating the dust collection unit from the main body and in the process of discharging dust inside the dust collector, indoor re-contamination There are problems that often occur.

  In addition, if the room is recontaminated in the process of removing dust, the user needs to clean again, which is inconvenient for the user.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a vacuum cleaner in which the structure of the dust collection unit is simplified and the dust collection capacity is maximized.

  Another object of the present invention is to provide a vacuum cleaner capable of easily discharging dust collected by the dust collection unit.

  In order to achieve the above object, a vacuum cleaner according to an aspect of the present invention includes a main body including a suction input generating device therein, and a first cyclone unit that is detachably attached to the main body and separates dust.

There is an advantage that the weight is reduced and the user can easily handle the dust collecting unit.

  Second, the secondary cyclone unit is configured to be separated from the dust collection unit, but the dust separated by the secondary cyclone unit is collected by the dust collection unit. As a result, only the dust collecting unit is separated from the cleaner body and the dust is discharged, so that the usability is increased.

  Third, the second dust collecting unit that collects the dust separated in the second cyclone unit collects the first dust collection that collects the dust separated in the first cyclone unit. By being provided outside the part, the size of the first dust collecting part is increased, and the dust collecting capacity is maximized.

  Fourth, if the dust collecting unit that collects dust is separated from the main body of the cleaner in a sealed state, and the user opens the cover member at a desired position, the upper part of the dust collecting body is completely opened. Therefore, there is an effect that indoor re-contamination can be prevented.

  Fifth, there is an advantage that dust can be easily discharged because the cover member provided on the upper side of the dust collecting unit simultaneously opens and closes the first dust collecting unit and the second dust collecting unit.

  Specifically, the vacuum cleaner body 100 is formed with an air discharge port 130 that allows the air sucked into the vacuum cleaner body 100 to be discharged to the dust collection unit 200. A first inlet 213 that allows air to flow in from the air outlet 130 is formed.

  At this time, the first inlet 213 is preferably formed in a tangential direction of the dust collection unit 200 so that a cyclone flow is generated inside the dust collection unit 200.

  In addition, the dust collection unit 200 is formed with a first discharge port 252 through which air from which dust has been separated in the primary cyclone unit is discharged, and the cleaner main body 100 has the first discharge port 252. A connection flow path 114 into which air discharged through the air flows is formed.

  In addition, the air that has flowed into the connection flow path 114 flows into the second cyclone unit 300.

  On the other hand, the secondary cyclone unit 300 is configured by connecting a large number of substantially conical small cyclones in parallel.

  Further, the secondary cyclone unit 300 is disposed in a state lying on the upper rear side of the cleaner body 100. That is, the secondary cyclone unit 300 is disposed in a state inclined with respect to the cleaner body 100 at a predetermined angle.

  As described above, by arranging the secondary cyclone unit 300 in a state lying on the vacuum cleaner main body 100, the space utilization degree of the vacuum cleaner that is required to be reduced in size in relation to the vacuum motor or the like can be obtained. Can be improved.

  Meanwhile, the dust separated by the secondary cyclone unit 300 is collected in the dust collection unit 200.

  Specifically, the dust collector 210 collects the dust inlet 254 into which the dust separated in the secondary cyclone unit 300 flows and the dust separated in the secondary cyclone unit 300. A dust collecting part is further formed.

  That is, the dust collector formed on the dust collector 210 is separated by the first dust collector that collects the dust separated by the primary cyclone and the secondary cyclone 300. It is comprised from the 2nd dust collection part where collected dust is collected.

  In other words, in the present embodiment, the secondary cyclone unit 300 is separated from the dust collecting unit 200 and configured in the vacuum cleaner main body 100, but the dust separated by the secondary cyclone unit 300 is The dust collecting unit 200 is configured to collect the dust.

  Here, it is preferable that the secondary cyclone unit 300 is disposed to be inclined downward on the dust collection unit 200 side so that the separated dust can be easily moved to the dust collection unit 200.

  With the above configuration, the operation of the vacuum cleaner 10 will be briefly described.

  First, when a power source is applied to the vacuum cleaner 10 and the cleaner main body 100 is activated, a suction input is generated by a vacuum motor provided therein. Further, air containing dust sucked into the suction nozzle by the suction input is sucked into the dust collection unit 200 along a predetermined flow path formed inside the connecting pipe and the cleaner body 100. The

  The air flowing into the second cyclone unit 300 is separated again, and the separated dust flows into the dust collecting unit 200 and is collected. The air from which the dust is separated is After flowing along a predetermined flow path inside the vacuum cleaner main body 100, it is finally discharged to the outside through the main body discharge portion 120.

  Hereinafter, the structure of the dust collection unit 200 will be described in detail.

  4 is a cross-sectional view taken along the line II ′ of FIG. 3, and FIG. 5 is a cross-sectional view taken along the line II-II ′ of FIG.

  As shown in FIGS. 4 and 5, the dust collection unit 200 according to the idea of the present invention includes a dust collector 210 having an outer shape, and dust from the air that is selectively housed in the dust collector 210 and sucked. Includes a primary cyclone unit 230 that selectively separates the dust collector 210 and a cover member 250 that selectively opens and closes the upper side of the dust collector 210.

  Specifically, the dust collector 210 is formed in a substantially cylindrical shape, and a dust collecting portion for collecting the separated dust is formed therein.

  The dust collecting unit collects the first dust collecting unit 214 that collects the dust separated by the primary cyclone unit 230 and the dust separated by the second cyclone unit 300. And a second dust collecting portion 216.

  Here, the dust collector 210 includes a first wall 211 that forms the first dust collecting portion 214 and a second wall that forms the second dust collecting portion 216 in relation to the first wall 211. 212. That is, the second wall 212 is formed so as to cover a predetermined portion of the first wall 211.

  Accordingly, the second dust collection unit 216 is formed outside the first dust collection unit 214.

  As described above, the second dust collecting part 216 is formed outside the first dust collecting part 214 so that the size of the first dust collecting part 214 can be maximized. Thus, there is an advantage that the dust collection capacity of the first dust collection unit 214 is maximized.

  Further, the first wall 211 is formed with a step jaw 219 in the circumferential direction for supporting the lower step of the first cyclone unit 230 housed therein. Therefore, the upper part of the first dust collecting part 214 has a larger diameter than the lower part with respect to the step jaw 219.

  The dust collector 210 includes a pair of pressure plates 221 and 222 that reduce the volume of dust collected in the first dust collector 214 and increase the dust collection capacity.

  Here, the pair of pressure plates 221 and 222 compress the dust by interaction with each other to reduce the volume of the dust, thereby increasing the density of the dust collected in the first dust collecting unit 214. As a result, the maximum dust collection capacity of the first dust collector 214 increases.

  Specifically, the pair of pressure plates 221 and 222 includes a fixed plate 222 fixed to a fixed shaft 224 protruding and formed on the bottom surface of the dust collector 210, and a rotating shaft rotatably coupled to the fixed shaft 224. The rotating plate 221 is fixed to the H.226.

  The rotary shaft 226 is coupled to a driven gear 228 that is rotated by an external drive source.

  Here, although not shown, the cleaner body 100 is provided with a drive gear that meshes with the driven gear 228 and a drive motor that drives the drive gear.

  Accordingly, when the drive motor is driven, the drive gear and the driven gear 228 are rotated, and the rotating plate 221 is rotated by the rotation of the driven gear 228.

  At this time, it is preferable that the rotating plate 221 is rotatable in both directions so that dust is compressed on both sides of the fixed plate 222. Accordingly, the driving motor is a synchronous motor. Can be used.

  In the present embodiment, at least one of the pair of pressure plates 221 and 222 is movably provided inside the dust collector 210. However, unlike the above, all of the pair of pressure plates 221 and 222 are provided. The dust collector 210 may be movable inside.

  Meanwhile, the dust collector 210 is formed so that the upper side is opened so that the user can turn the dust collector 210 upside down and discharge the dust. The cover member 250 is detachably coupled.

  In addition, the primary cyclone unit 230 is configured so that the primary cyclone unit 230 can be separated together with the cover member 250 when the dust collected in the dust collector 210 is discharged. Coupled to the underside of 250.

  Here, the present embodiment is configured such that the primary cyclone unit 230 is coupled to the cover member 250. However, unlike the first cyclone unit 230 and the cover member 250, It is clear that they can be formed in one piece.

  Meanwhile, the first cyclone unit 230 is formed with a dust guide channel 232 that guides dust separated from air so that the dust can be easily discharged to the first dust collecting unit 214.

  Here, the dust guide channel 232 guides the separated dust to flow downward after being allowed to flow in the tangential direction.

  Therefore, the inlet 233 of the dust guide channel 232 is formed on the side surface of the primary cyclone unit 230, and the discharge port 234 is formed on the bottom surface of the primary cyclone unit 230.

  Meanwhile, the cover member 250 is detachably coupled to the upper side of the dust collector 210 as described above. That is, the cover member 250 opens and closes the first dust collecting unit 214 and the second dust collecting unit 216 simultaneously.

  Therefore, in order to discharge the dust collected by the first dust collecting unit 214 and the second dust collecting unit 216 to the outside, a user can cover the cover member 250 to which the first cyclone unit 230 is coupled. Is separated from the dust collector 210, the upper side of the dust collector 210 is completely opened. Also, if the user turns the dust collector 210 over, the dust is easily discharged.

  At this time, in order to remove dust from the dust collector 210, the user separates the cover member 250 from the dust collector 210 outside the trash can or outdoors, thereby preventing indoor recontamination.

  In addition, a discharge hole 251 through which air from which dust is separated by the primary cyclone unit 230 is discharged is formed through the bottom surface of the cover member 250. The discharge hole 251 is coupled to the upper side of a filter member 260 having a plurality of through holes 262 having a predetermined size on the outer peripheral surface.

  Therefore, the air that has primarily undergone the dust separation process in the primary cyclone unit 230 is discharged to the discharge hole 251 through the filter member 260.

  In addition, a flow path 253 for guiding the air of the primary cyclone unit 230 discharged from the discharge hole 251 to move toward the first discharge port 252 is formed in the cover member 250. . That is, the flow path 253 serves as a passage connecting the discharge hole 251 and the first discharge port 252.

  Further, the cover member 250 has a dust inlet 254 into which dust separated by the secondary cyclone unit 300 flows, and air that has flowed into the cover member 250 through the dust inlet 254 has the second flow. A dust discharge port 257 is formed so as to be discharged to the dust collecting portion 216.

  Specifically, the dust inlet 254 is formed on the upper side of the cover member 250. The dust inlet 254 is formed symmetrically on both sides of the first outlet 252 as shown in FIG. The dust discharge port 257 is formed on the bottom surface of the cover member 250.

  As described above, the dust inlet 254 is formed on the upper side of the cover member 250, and the dust outlet 257 is formed on the bottom surface of the cover member 250, whereby the dust inlet 254, the dust outlet 257, A space is formed between them.

  Therefore, it is preferable that the dust flowing into the dust inlet 254 is easily moved to the dust outlet 257. For this reason, in the present invention, the dust flowing into the dust inlet 254 is Dust guide ribs 258 are provided to guide the second dust collecting part 216 through the dust discharge port 257 so as to be easily moved.

  Specifically, the dust guide rib 258 is formed to extend from the dust inlet 254 to the dust outlet 257. Accordingly, the dust guide rib 258 has a shape corresponding to the dust inlet 254 on one side and a shape corresponding to the dust outlet 257 on the other side.

  Due to the dust guide ribs 258, the cover member 250 is formed with a dust channel 259 through which the dust separated by the secondary cyclone unit 300 flows.

  Due to the dust guide rib 258, the dust flowing in through the dust inlet 254 can be easily moved to the dust outlet 257, and the dust flowing into the dust inlet 254 can be moved to the cover member 250. It is possible to prevent the phenomenon that accumulates inside.

  As described above, the present embodiment is characterized in that the primary cyclone unit 230 is provided in the dust collecting unit 200 and the secondary cyclone unit 300 is provided in the cleaner body 100.

  However, unlike the first cyclone unit and the second cyclone unit, a third cyclone unit may be further provided. In such a case, the third cyclone unit is also provided with the vacuum cleaner. The body 100 may be formed.

  As another example, the dust collection unit 200 may be provided with primary and secondary cyclone units, and the cleaner main body 100 may be provided with a tertiary cyclone unit.

  That is, the idea of the present invention is that the cyclone unit having at least one order among the cyclone units having a large number of orders is provided in the dust collecting unit 200, and the cyclone parts of other orders are provided in the cleaner main body 100. Including that.

  If it demonstrates from another side surface, the cyclone part with which the said dust collection unit 200 is equipped can be made into a dust collection unit cyclone part, the cyclone part with which the said vacuum cleaner main body 100 is equipped can be made into a main body cyclone part, The dust collection unit cyclone unit and the main body cyclone unit may be provided with at least a first order.

  FIG. 6 is a perspective view illustrating a state where a guide cover is separated from the vacuum cleaner.

  As shown in FIG. 6, in the vacuum cleaner 10 according to the idea of the present invention, the second cyclone unit 300 is disposed on the upper side of the cleaner body 100 as described above.

  In addition, a connection channel 114 is provided below the second cyclone unit 300 to guide the air discharged from the dust collection unit 200 to be moved to the second cyclone unit 300.

  In addition, the second cyclone unit 300 is provided with a second inlet 302 that allows the air that has passed through the connection flow path 114 to flow into the second cyclone unit 300.

  At this time, a guide rib 304 is provided on the second inflow port 302 side so that the air that has passed through the connection channel 114 can flow in the tangential direction of the second cyclone unit 300. It is formed in the tangential direction of the part 300.

  Meanwhile, the cleaner body 100 is formed with an air inflow hole (see 118 in FIG. 7) into which air from which dust has been removed by the secondary cyclone unit 300 is introduced.

  Here, the air inflow hole (refer to 118 in FIG. 7) and the secondary cyclone unit 300 are configured such that the guide cover 160 is attached to the secondary cyclone unit 300 and the cleaner body 100. Communicated.

  In addition, air sucked through the suction nozzle flows into the cleaner body 100 through the main body suction portion 110, and the air that flows in flows into the dust collection unit 200 through the communication channel 112.

  Specifically, the air containing the dust is sucked in the tangential direction of the primary cyclone unit 230 through the first inlet 213 of the dust collector 210. Inhaled air falls while swirling along the inner circumferential surface of the primary cyclone unit 230. In this process, the air and dust are subjected to different centrifugal forces depending on their weights, and each other, Separation takes place.

  Further, the air from which the dust has been separated is filtered through the through hole 262 of the filter member 260 and then discharged to the outside of the dust collecting unit 200 through the discharge hole 251 and the first discharge port 252.

  Meanwhile, the separated dust flows into the dust guide channel 232 in a tangential direction in a process of turning along the inner circumferential surface of the primary cyclone unit 230.

  Also, the dust flowing into the dust guide channel 232 flows along the outer circumferential surface of the primary cyclone unit 230 with the flow direction being switched inside the dust guide channel 232, and the discharge port 234. Through the first dust collecting unit 214.

  Meanwhile, the air discharged through the first discharge port 252 flows into the cleaner body 100. In addition, the air that has flowed into the cleaner main body 100 flows into the secondary cyclone unit 300 through the connection channel 114.

  Such air is guided tangentially to the inner wall of the secondary cyclone unit 300 through the second inlet 302 formed at the end of the connection channel 114, and dust flows again while flowing through the inside. To be separated.

  The air from which the dust has been separated again flows into the discharge passage 116 and then flows into the cleaner body 100 through the air inflow hole 118. In addition, the air that has flowed into the cleaner body 100 is discharged to the outside through the motor pre-filter 152 and the vacuum motor 150 through the body discharger 120 on the side of the cleaner body 100.

  On the other hand, the separated dust flows into the dust collecting unit 200 through the dust inlet 254 and is finally collected by the second dust collecting unit 216.

  Meanwhile, the user separates the dust collection unit 200 from the cleaner body 100 in order to remove dust collected by the dust collector 210.

  Further, the cover member 250 to which the primary cyclone unit 230 is coupled is separated from the dust collection unit 200. Further, the dust collector 210 is turned over to remove dust.
