  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. Each unit includes a partition wall for partitioning the inside of the dust collection box, and the dust collection box includes an upper dust collection box that is an upper part and a lower dust collection box that is a lower part. An upper partition wall extending downward from the upper dust collection box and a lower partition wall extending upward from the lower dust collection box, the lower dust collection box being detachable from the upper dust collection box, and The partition wall is provided with backflow prevention means for preventing a backflow of airflow from the dust collection box through the dust discharge port into the swivel unit, and the backflow prevention means is provided on the upper dust collection box. When mounting the collection box, the upper partition walls and said lower partition walls are overlapping if cormorants structure, an inclined surface provided on the upper surface of each of the lower partition wall, thereby is to achieve 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. A partition wall for partitioning the inside of the dust collection box is provided, and the dust collection box includes an upper dust collection box that is an upper part and a lower dust collection box that is a lower part, and the partition wall is separated from the upper dust collection box. An upper partition wall extending upward and a lower partition wall extending upward from the lower dust collection box, and the lower dust collection box is detachable from the upper dust collection box and is attached to the partition wall. A backflow prevention means for preventing a backflow of airflow from the inside of the collection box through the dust discharge port into the swivel unit is provided, and the backflow prevention means attaches the lower dust collection box to the upper dust collection box. , the upper partition wall and a case cormorants structure overlap with the lower partition wall, is provided with the inclined surface on the upper surface of each of the lower partition wall, it can be made high dust collecting effect.

  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.

  Further, the dust collection box includes a partition wall for partitioning the inside of the dust collection box for each swivel unit, and the dust collection box includes an upper upper dust collection box and a lower lower dust collection box. The partition wall is composed of an upper partition wall extending downward from the upper dust collection box and a lower partition wall extending upward from the lower dust collection box, and the lower dust collection box is formed of the upper dust collection box. Since it is detachable from the box and provided with a backflow prevention means on the partition wall, the airflow in the dust collection box is caused by a part of the airflow blown out with dust from the dust outlet provided in the swivel wall of each swivel unit. The state is affected, and as a result, the dust collection effect for each swivel unit is not reduced.

  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. Backflow prevention means was provided on the partition wall that partitions the inside of 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 to 5, 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 is configured such that the swivel walls 9 of the swivel units 8 are arranged in the horizontal direction, and the lower part of the swivel wall 9 of each swivel unit 8 is the above-described structure. It is an airflow suction part 2.

  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.

  The dust collection box 7 is divided into upper and lower parts, and includes an upper dust collection box 7a as an upper part and a lower dust collection box 7b as a lower part. The upper dust collection box 7a has a substantially bowl shape with a lower surface opened, and the lower dust collection box 7b has a substantially bowl shape with an upper surface opened.

  As shown in FIGS. 5 to 7, the dust collection box 7 is provided with an upper partition wall 11 and a lower partition wall 12 for partitioning the dust collection box 7 for each swivel unit 8.

  Among these, the upper partition wall 11 is disposed in the upper dust collection box 7a, which is the upper part of the dust collection box 7, and the lower partition wall 12 is disposed in the lower dust collection box 7b, which is the lower part of the dust collection box 7. It is. The upper partition wall 11 has a plate shape extending downward from the upper dust collection box 7a, and the lower partition wall 12 has a plate shape extending upward from the lower dust collection box 7b.

  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 upper partition wall 11 and the lower partition wall 12 for each turning unit 8.

  Further, as shown in FIG. 8, backflow prevention means 13 is provided so that no airflow is generated between the upper partition wall 11 and the lower partition wall 12.

  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 this embodiment, as described above, the upper partition wall 11 and the lower partition wall 12 for partitioning the inside of the dust collection box 7 are provided in the dust collection box 7 for each swivel unit 8, and Since the upper partition wall 11 and the lower partition wall 12 are provided with the backflow prevention means, a part of the air flow blown out with the dust from the dust discharge port 10 of each swivel unit 8 is a dust discharge port of the other swivel unit 8. As a result, the dust collection effect for each swivel unit 8 is not lowered.

  FIG. 9 is a diagram used to explain this point. In the dust collection box 7, an upper partition wall 11 and a lower partition wall 12 for partitioning the dust collection box 7 are provided for each swivel unit 8. Not provided.

  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. 9, this air flow has directivity along the turning direction (directivity in the left direction in FIG. 9) 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. 9) 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. 9) 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. 9), 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.

  On the other hand, in this embodiment, an upper partition wall 11 and a lower partition wall 12 for partitioning the inside of the dust collection box 7 are provided in the dust collection box 7 for each swivel unit 8. Since the partition wall 11 and the lower partition wall 12 are provided with a backflow prevention means, the pressure difference in the dust collection box 7 is large due to a part of the airflow blown out with the dust from the dust discharge port 10 of each swivel unit 8. The reverse flow to the swivel unit 8 at the dust outlet 10 does not increase with respect to the specific swivel unit 8. 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 upper partition wall 11 and the lower partition wall 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 arrow. Further, since the upper partition wall 11 and the lower partition wall 12 are provided with curved surfaces for curving and guiding the airflow discharged from the dust discharge port 10 of the swivel unit 8 to the outside of the swivel unit 8, the dust discharge port of the swivel unit 8 is provided. The airflow discharged from the swivel unit 8 to the outside of the swivel unit 8 flows smoothly in the blowing direction, and this does not increase the airflow resistance of the airflow discharged from the dust discharge port 10 of the swivel unit 8 into the dust collection box 7. In addition, the turbulence of the airflow in the dust collection box 7 is reduced, and the dust once separated falls by gravity while riding on the smooth airflow flowing along the upper partition wall 11 and the lower partition wall 12. .

  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, in the present embodiment, as shown in FIG. 8, when the dust collection box 7 is mounted in the main body case 1, the backflow prevention means 13 is provided so that the upper partition wall 11 and the lower partition wall 12 overlap each other. Is. By providing the backflow prevention means 13, the degree of sealing between the upper partition wall 11 and the lower partition wall 12 is increased, and as a result, the separation of large dust and the reduction of the waste power do not occur.

  Further, in the present embodiment, by providing the upper partition wall 11 so that the height thereof becomes lower in order, the dust collecting box 7 is provided even if the upper partition wall 11 and the lower partition wall 12 are overlapped by the backflow prevention means 13. Is removable from the body case. At that time, the height of the lower partition wall 12 also changes corresponding to the height of the upper partition wall 11.

  Specifically, as shown in FIGS. 3 and 7, the lower dust collection box 7b has a structure that can be pulled out from the upper dust collection box 7a in the direction of the arrow. The position of the lower end of the upper partition wall 11 of the upper dust collection box 7a is sequentially increased from the upstream side to the downstream side in this pulling direction. Similarly, the position of the upper end of the lower partition wall 12 of the lower dust collection box 7b is sequentially increased from the upstream side to the downstream side in the pulling direction. Here, when the lower dust collection box 7b is mounted on the upper dust collection box 7a, the lower end portion of each upper partition wall 11 and the upper end portion of each lower partition wall 12 overlap each other in the vertical plane, and the lower dust collection box When pulling out 7b from the upper dust collection box 7a, the lower end of the upper partition wall 11 and the upper end of the lower partition wall 12 are not in contact with each other. That is, when the lower dust collection box 7b is attached to the upper dust collection box 7a, the upper end position of each lower partition wall 12 is higher than the lower end position of each upper partition wall 11, and overlaps. On the other hand, when the lower dust collection box 7b is pulled out from the upper dust collection box 7a, the upper end of each lower partition wall 12 is configured to be lower than the lower end of the adjacent one upper downstream partition wall 11. Is. As a result, the structure is detachable, and the upper partition wall 11 and the lower partition wall 12 overlap each other when mounted, and serve as the backflow prevention means 13.

  In the present embodiment, an inclined surface is provided on the upper surface of the lower partition wall 12. This inclination is inclined downward as it goes from the upstream side to the downstream side in the pull-out direction. As a result, dust does not accumulate on the upper surface of the lower partition wall 12 and falls to the lower part of the dust collection box 7, so that it does not wind up due to the air current, and from this point, the dust collecting effect is high.

  As described above, the present invention has a configuration in which 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. 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.

  Further, the dust collection box includes a partition wall for partitioning the inside of the dust collection box for each swivel unit, and the dust collection box includes an upper upper dust collection box and a lower lower dust collection box. The partition wall is composed of an upper partition wall extending downward from the upper dust collection box and a lower partition wall extending upward from the lower dust collection box, and the lower dust collection box is formed of the upper dust collection box. Since it is detachable from the box and provided with a backflow prevention means on the partition wall, the airflow in the dust collection box is caused by a part of the airflow blown out with dust from the dust outlet provided in the swivel wall of each swivel unit. The state is affected, and as a result, the dust collection effect for each swivel unit is not reduced.

  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. Backflow prevention means was provided on the partition wall that partitions the inside of 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.
