Description

  The present invention relates to a dust collector provided with dust swirl separating means.

  This type of conventional dust collector is widely used in vacuum cleaners, a main body case having an airflow suction portion and an airflow outlet, and provided in the main body case, and sucked into the main body case from the airflow suction portion. A fan that discharges the airflow from the airflow blowing portion to the outside of the main body case, and the air that is sucked into the main body case via the airflow suction portion by the fan is swirled to separate dust contained in the sucked airflow. It is the structure provided with the turning unit (For example, the following patent document 1 exists as prior literature similar to this).

JP 2000-157463 A

  In the above conventional example, when the fan is driven, first, the airflow is sucked into the main body case from the airflow suction portion, and then this airflow is swirled by the swivel unit, and thereby included in this sucked airflow. Dust is separated and collected.

  For example, in the case of a vacuum cleaner, a suction nozzle that is movably operated is connected to the airflow suction portion of the main body case, and dust can be collected in a wide area by moving the suction nozzle to a portion to be cleaned.

  However, a dust collector that does not use a movable suction nozzle, that is, a dust collector that collects dust in the vicinity of the main body case in a state where the main body case is placed, has only one swivel unit. Only dust can be collected, and the dust collection effect is low.

  Then, this invention aims at heightening the dust collection effect.

  And in order to achieve this object, the present invention provides a main body case having an airflow suction portion and an airflow outlet portion, and an airflow that is provided in the main body case and sucked into the main body case from the airflow suction portion, A fan that discharges from the airflow outlet to the outside of the main body case, and a dust swirl separating means for rotating the airflow sucked into the main body case via the airflow suction portion by the fan and separating the dust contained in the sucked airflow The dust swirl separating means includes a plurality of swivel units, and a dust collection box connected to the outside of the dust discharge port provided on the swivel wall of each swivel unit. A partition wall for partitioning the inside of the dust collection box is provided for each unit, thereby achieving the intended purpose.

  As described above, the present invention provides a main body case having an airflow suction portion and an airflow blowout portion, and an airflow provided in the main body case from the airflow suction portion into the main body case from the airflow blowout portion. A fan for discharging outside the case, and a dust swirl separating means for rotating the air flow sucked into the main body case through the air flow suction portion by the fan and separating the dust contained in the sucked air flow, The dust swirl separating means has a plurality of swivel units and a dust collection box connected to the outside of the dust discharge port provided on the swivel wall of each swivel unit. Since the partition wall for partitioning the dust collection box is provided, the dust collection effect can be enhanced.

  That is, the dust swirl separating means of the present invention has a plurality of swivel units and a dust collection box connected to the outside of the dust discharge port provided on the swivel wall of each swivel unit. The dust can be collected in a dust collection box connected to the outside of the dust discharge port provided on the swivel wall of each swivel unit, and the dust collecting effect can be enhanced.

  In addition, since a partition wall for partitioning the inside of the dust collection box is provided for each swivel unit in the dust collection box, a part of the swirl unit is blown out together with dust from the dust discharge port provided on the swivel wall of each swivel unit. As a result, the dust collecting effect for each swivel unit is not lowered.

  That is, since the air flow blown out from the dust outlet of the swivel unit also enters the dust outlet of the other swivel unit, in the present invention, the dust collection is performed for each swivel unit in the dust collection box. A partition wall was provided to partition the box.

  For this reason, a part of the airflow blown out with dust from the dust outlet of each swivel unit has less influence on the dust outlets of other swivel units. The effect will not decline.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
1 and 2, reference numeral 1 denotes a box-shaped main body case having an airflow suction portion 2 below and an airflow outlet portion 3 above.

  A fan 4 is provided in the main body case 1. When the fan 4 is driven, air outside the main body case 1 is sucked into the main body case 1 from the airflow suction portion 2, and then the dust swirl separating means 5 is operated. And then passes through the filter 5a.

  Part of the airflow that has passed through the filter 5a passes through the humidifying body 6, the other part passes around the humidifying body 6, and then passes through the fan 4, and then passes from the air blowing part 3 to the outside of the main body case 1. It is blown out.

  That is, among the dust contained in the airflow sucked into the main body case 1 from the airflow suction portion 2, a large one is separated by being swirled by the dust swirl separating means 5 and collected in the dust collecting box 7. The

  Of the dust contained in the airflow sucked into the main body case 1 from the airflow suction portion 2, small dust passes through the dust swirl separating means 5, and is then collected by the filter 5a.

  Then, a part of the airflow from which dust has been removed is humidified by passing through the humidifying body 6, passes through the fan 4 together with the airflow that has passed around the humidifying body 6, and then from the airflow blowing unit 3 to the main body case 1. It is blown out.

  As shown in FIGS. 3 and 4, the dust swirl separating means 5 of the present embodiment has a configuration in which a plurality of swivel units 8 are arranged in the horizontal direction.

  That is, as shown in FIGS. 3 to 5, the swivel unit 8 has a structure in which the swirl walls 9 of the swivel units 8 are arranged in the horizontal direction so that the air passages are arranged in parallel. The lower part of the eight revolving walls 9 is the airflow suction part 2. Further, the dust discharge port 10 provided at the upper part of the side wall of the swivel wall 9 is configured to open into the dust collection box 7.

  In order to make air swirl smooth, the swivel unit 8 is preferably cylindrical. Further, the dust discharge port 10 is a substantially rectangular opening having an end 10 a on the upstream side of the swirl flow and an end 10 b on the downstream side of the swirl flow in the swirling direction of the air in the swivel unit 8. The end portion 10a on the upstream side of the swirl flow and the end portion 10b on the downstream side of the swirl flow are sides parallel to the cylindrical height direction in the rectangular opening. However, the swirl unit 8 is cylindrical and the dust discharge port 10 is a substantially rectangular opening having an end 10a on the upstream side of the swirl flow and an end 10b on the downstream side of the swirl flow. Therefore, the configuration is not essential in the first embodiment. For this reason, when the fan 4 is driven, the airflow that has entered the dust swirl separating means 5 from the airflow suction section 2 is swung by the swirl wall 9, and the airflow sucked into the main body case 1 from the airflow suction section 2 by this swirling. Of the dust contained in the dust is separated and collected from the dust outlet 10 provided in the swivel wall 9 to the dust collection box 7.

  In the dust collection box 7, partition walls 11 and 12 for partitioning the dust collection box 7 are provided for each swivel unit 8.

  Among these, the partition wall 11 is disposed at the upper part (7a) of the dust collection box 7, and the partition wall 12 is disposed at the lower part (7b) of the dust collection box 7.

  That is, although the dust collection box 7 is divided into upper and lower parts, the inside of the dust collection box 7 is partitioned by the partition walls 11 and 12 for each turning unit 8.

  More specifically, the lower dust collection box 7 portion is detachable from the main body case 1 and is drawn out when the dust collected in the lower dust collection box 7 portion is discarded. Again, as shown in FIG. 3, the main body case 1 is mounted.

  Now, among the dust contained in the airflow sucked into the main body case 1 from the airflow suction portion 2, a large amount of dust, together with a part of the airflow, is transferred from the dust discharge port 10 provided in the turning wall 9 to the dust collection box 7. Separated and recovered.

  At this time, in the present embodiment, as described above, the partition walls 11 and 12 for partitioning the inside of the dust collection box 7 are provided for each swivel unit 8 in the dust collection box 7. Thus, a part of the air flow blown out with the dust from the dust discharge port 10 of the 8 has less influence on the dust discharge ports of the other swivel units 8, and as a result, the dust collection effect for each swivel unit 8 is increased. It will not drop.

  FIG. 7 is a diagram used to explain this point. In the dust collection box 7, partition walls 11 and 12 for partitioning the dust collection box 7 are not provided for each swivel unit 8.

  For this reason, a part of the airflow is blown out together with dust from the dust discharge port 10 provided in the revolving wall 9 of each revolving unit 8. As shown in FIG. 7, this air flow has directivity along the turning direction (directivity in the left direction in FIG. 7) as indicated by an arrow from the dust outlet 10 toward the outside of the turning unit 8. It has become an air current. As a result, the air pressure on the airflow blowing side (left side in FIG. 7) in the dust collection box 7 is increased, and the airflow flowing from the airflow blowing side to the opposite side (left side to right side in FIG. 7) as indicated by the white arrow in FIG. As a result, a state occurs in which the airflow flows backward from the dust discharge port 10 on the side opposite to the airflow blowing in the dust collection box 7 (right side in FIG. 7), and this backflow becomes stronger toward the right side in FIG. As a result, the dust collecting effect is reduced as the right-side swivel unit 8 is moved.

  In contrast, in the present embodiment, partition walls 11 and 12 for partitioning the inside of the dust collection box 7 are provided in the dust collection box 7 for each swivel unit 8. The pressure difference in the dust collection box 7 is not increased by a part of the airflow blown out with the dust from the dust discharge port 10, and the reverse flow to the swivel unit 8 at the dust discharge port 10 is also caused by the specific swivel unit 8. On the other hand, it will not grow. As a result, the dust collection effect for each swivel unit 8 is not reduced.

  Further, in the present embodiment, as shown in FIG. 5, the partition walls 11 and 12 are provided along the direction of the airflow directed from the dust outlet 10 toward the outside of the swivel unit 8 as indicated by the arrows. In other words, the partition walls 11, 12 are directed from the end portion 10 b on the downstream side of the swirl flow that forms the dust discharge port 10 into the dust collection box 7 in order to keep the air flow from the dust discharge port 10 to the outside of the swivel unit 8. Further, a straight tangential line 10c drawn into the dust collection box 7 from the end 10a on the upstream side of the swirl flow that forms the same dust discharge port 10 is provided into the dust collection box 7. It is provided so as to move away as it moves forward. Furthermore, the partition walls 11 and 12 are provided with curved surfaces that guide the airflow discharged from the dust discharge port 10 of the swivel unit 8 to the outside of the swivel unit 8 at the position farthest from the swivel unit 8. Thereby, the airflow discharged from the dust discharge port 10 of the swivel unit 8 to the outside of the swivel unit 8 smoothly flows in the blowing direction, and is thereby discharged from the dust discharge port 10 of the swivel unit 8 into the dust collection box 7. The airflow in the dust collection box 7 is less disturbed and the dust once separated is gravity while riding on the smooth airflow that flows along the partition walls 11 and 12. Will fall by.

  That is, the turning force in the turning unit 8 does not decrease, and as a result, the separation of large dust and the reduction of the discarding force do not occur.

  Further, since the partition walls 11 and 12 are formed of synthetic resin (an example of an insulating material), the partition walls 11 and 12 are charged by the airflow passing through the surfaces of the partition walls 11 and 12.

  Dust is charged by friction between the dusts and friction between the dust and the turning wall 9 while turning in the turning unit 8. When the charged dust is discharged from the dust discharge port 10 and approaches the partition walls 11 and 12, the insulating synthetic resin surface is charged to the opposite polarity to the dust by induction charging. As a result, the partition wall 11 , 12 will adhere to the surface and roll here, forming a larger lump and falling to the lower part of the dust collection box 7. That is, since the dust which became a big lump exists in the lower part of the dust collection box 7, this does not wind up with an air current, and the dust collection effect is also high from this point.

(Embodiment 2)
As described above, in the first embodiment, the basic configuration of the embodiment has been described. In addition, in the present embodiment, the configuration of the inclined portion 13 provided below the dust discharge port 10 in the dust collection box 7 will be described.

  FIG. 8 is an enlarged plan view of one space in which the dust collection box 7 is partitioned by the partition wall 11. The swivel unit 8 is a cylindrical body, and the side surface of the cylindrical body is adjacent to the side surface of the rectangular parallelepiped dust collection box 7. That is, as shown in FIG. 8, the swirl unit 8 is adjacent to the dust collection box 7 at the end 10b on the downstream side of the swirl flow, and the end 10a on the upstream side of the swirl flow is arranged at the dust collection box 7 as shown in FIG. It is located in the middle of the inclined surface of the inclined portion 13 located on the upper (7a) side and above the inclined portion 13. FIG. 9 shows the bottom shape of the dust collection box 7, and is a cross-sectional view taken along the line CC of FIG.

  The inclined portion 13 is an inclined surface located on the upper side surface of the adjacent swivel unit 8 and the upper portion (7a) of the dust collection box 7. In the plan view of FIG. 8, the line 13a connecting the end portion on the downstream side of the swirling flow and the surface surrounded by the side surface of the swirling unit 8, and adjacent to the line 13a side connecting the end portion on the downstream side of the swirling flow. It is the inclined surface which raised the position side which the side surface of the swivel unit 8 contacted.

  With these configurations, a return path for the airflow that flows into the dust collection box 7 from the dust discharge port 10 is formed in the upper part (7a) of the dust collection box 7.

  A swirl flow in the swivel unit 8 causes an airflow to flow into the dust collection box 7 from the dust discharge port 10 into the dust collection box 7. The flow of airflow in the dust collection box 7 at this time (the airflow in the return path) is shown in FIG. Are indicated by arrows. In the present embodiment, the partition walls 11 and 12 first extend linearly from the downstream end of the swirling flow of the dust discharge port 10, and then draw a curve. Thereby, the air stream containing dust can be guided to a position away from the dust outlet 10 without being disturbed, and thereafter, the direction of the air stream is smoothly changed by the curved partition wall 11. It is collected when dust collides with the curved partition wall 11. Since the part where dust is collected is away from the dust discharge port 10, it is possible to prevent the dust from returning to the turning unit 8 again. Furthermore, after that, it flows along the linear partition wall 11 extended from the adjacent turning wall 9, collides with the adjacent turning wall 9, and dust can be collected here.

  The bottom surface between the swivel units 8 is inclined, and the inclined portion 13 is likely to accumulate due to the collision of dust as described above. The dust accumulated on the inclined portion 13 becomes a large lump and rolls according to its own weight and falls to the lower part of the dust collection box 7.

  That is, since the dust which became a big lump exists in the lower part of the dust collection box 7, this does not wind up with an air current, and the dust collection effect is also high from this point.

(Embodiment 3)
This embodiment includes a scattering prevention plate 14 shown in FIG. 10 in addition to the configurations of the first and second embodiments. The anti-scattering plate 14 is discharged into the dust collection box 7 in the direction of the imaginary tangent line 10c from the end 10a on the upstream side of the swirl flow.

  The dust collection box 7 has an air flow as indicated by arrows in FIG. 8, and dust accumulated on the inclined portion 13 and dust remaining in the air flow are returned to the swivel unit 8 from the dust discharge port 10 again. In order to prevent this, a scattering prevention plate 14 is provided. The anti-scattering plate 14 has a shape extending from the upstream end in the swirling flow of the dust discharge port 10 to a position tangent to the position where the inclined portion 13 ends, thereby enhancing the anti-scattering effect. This is because the accumulated dust falls downward when the airflow passes over the scattering prevention plate 14 and returns to the dust discharge port 10. Even if the anti-scattering plate 14 extends to the front or back of the inclined portion 13, the anti-scattering effect is obtained.

  That is, the scattering prevention plate 14 has an effect of preventing the dust flowing into the dust collection box 7 from returning to the turning unit 8 again, and has a high dust collection effect.

  As described above, the present invention has a configuration in which the dust swirl separating means includes a plurality of swivel units and a dust collection box connected to the outside of the dust discharge port provided on the swivel wall of each swivel unit. As a result, dust in a wide area can be collected in a dust collection box connected to the outside of the dust discharge port provided on the revolving wall of each revolving unit, and the dust collecting effect can be enhanced.

  In addition, since a partition wall for partitioning the inside of the dust collection box is provided for each swivel unit in the dust collection box, a part of the swirl unit is blown out together with dust from the dust discharge port provided on the swivel wall of each swivel unit. As a result, the dust collecting effect for each swivel unit is not lowered.

  That is, since the air flow blown out from the dust outlet of the swivel unit also enters the dust outlet of the other swivel unit, in the present invention, the dust collection is performed for each swivel unit in the dust collection box. A partition wall was provided to partition the box.

  For this reason, a part of the airflow blown out with dust from the dust outlet of each swivel unit has less influence on the dust outlets of other swivel units. The effect will not decline.

  Therefore, it is expected to be used as a dust collector used in homes and offices.
