Description

  The present invention relates to a dust collector, and is applied to, for example, a vacuum cleaner. The present invention relates to a dust collector that exhausts air through an exhaust pipe attached to an exhaust port.

  An example of a conventional vacuum cleaner of this type is disclosed in Patent Document 1. According to this prior art, a dust collector using a cyclone mechanism is connected to a cleaner body provided with an electric blower via a shaft tube, a handle tube and a hose. The dust collector is formed in a cylindrical shape, and the air containing dust is taken in from the tangential direction of the inner periphery of the cylinder.

The taken-in dust and air swirl within the cylinder, and relatively large dust such as cotton dust and sand dust is separated from the air by centrifugal force. The separated dust falls by its own weight and is stored in a dust collection chamber provided below. On the other hand, small dust that could not be separated by the dust collector is separated from air by a dust container in the cleaner body. Both the dust collection chamber and the dust container are detachable. The dust accumulated in the dust collection chamber is discarded into the trash bin by removing the dust collection chamber from the dust collector and directing the opening downward. On the other hand, the dust accumulated in the dust container is discarded together with the dust container.

  However, part of the dust accumulated in the dust collection chamber does not fall even when the opening portion is directed downward, and remains in the dust collection chamber. Such dust can be removed only by washing with water or the like, and it takes time to maintain the dust collection chamber.

  Therefore, a main object of the present invention is to provide a dust collecting device that can easily remove dust remaining in the dust collecting chamber.

  In the dust collector according to the first aspect of the present invention, the outside air sucked from the intake port is swirled by the swirler to separate the dust and air from each other, the dust is accumulated in the dust collecting case, and the air is attached to the exhaust port. In the dust collector that discharges through the exhaust pipe, the swirler and the exhaust port are separated by a partition wall having a hole into which the exhaust pipe is inserted, and the first end portion is located at a first distance from one end of the exhaust pipe. And an engagement member having a second end at a position spaced a second distance from the other end of the exhaust pipe is formed on the outer peripheral surface of the exhaust pipe, and the partition wall, the first end and the second end are It is characterized in that the insertion position of the exhaust pipe is defined by contacting one of them.

  The outside air sucked from the intake port is swirled by a swirler, whereby dust and air are separated from each other. The separated dust accumulates in the dust collection case, and the separated air is discharged through an exhaust pipe attached to the exhaust port. Here, the swirler and the exhaust port are separated by a partition wall having a hole into which the exhaust pipe is inserted. In addition, the outer periphery of the exhaust pipe has a first end portion at a position spaced from the one end of the exhaust pipe by a first distance, and a second end portion at a position spaced from the other end of the exhaust pipe by a second distance. Is formed. The insertion position of the exhaust pipe is defined by bringing the partition wall into contact with one of the first end and the second end.

  Therefore, the distance from the inserted end to the inner wall of the dust collecting case differs depending on whether the exhaust pipe is inserted from the first end or the second end. Due to this difference in distance, when inserted from one of the first end and the second end, only the air separated by the swirler can be discharged, and the other of the first end and the second end is When inserted, the dust accumulated in the dust collection case can be discharged. As a result, dust remaining in the dust collection case can be removed.

  The dust collector according to the invention of claim 2 is dependent on claim 1, and one end and the other end of the exhaust pipe are tapered. As a result, the exhaust pipe can be connected to another pipe, and the air or dust can be easily discharged.

  A dust collector according to a third aspect of the present invention is dependent on the second aspect, and the angle of the tapered surface with respect to the length direction of the exhaust pipe coincides between the one end and the other end. As a result, another pipe connected to the exhaust pipe can be shared for discharging air and discharging dust.

  A dust collector according to a fourth aspect of the invention is dependent on any one of the first to third aspects, wherein the first distance is a distance that can prevent the dust accumulated in the dust collection case from being discharged, and the second distance is a dust collection case. It is a distance that enables the dust accumulated on the surface to be discharged. When the discharge pipe is inserted from the first end, it is suitable for normal use, and when the discharge pipe is inserted from the second end, it is suitable for dust removal.

  According to this invention, when inserted from one of the first end and the second end, only the air separated by the swirler can be discharged, and the other of the first end and the second different end is When inserted, the dust accumulated in the dust collection case can be discharged. As a result, dust remaining in the dust collection case can be removed.

  The above object, other objects, features, and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  A vacuum cleaner 10 according to an embodiment of the present invention shown in FIG. 1 has a floor suction tool 12 for taking in dust together with air, a cyclone dust collecting device 16 and a cleaner main body 28. The floor suction tool 12 is connected to a dust collector 16 by a shaft tube 14, and the dust collector 16 is connected to a cleaner body 28 via a handle tube 24 and a hose 26.

  The handle tube 24 includes a switch 24 a for operating the electric vacuum cleaner 10. The power on / off operation at the switch 24 a is transmitted to the electric blower 32 of the cleaner main body 28 via a cord included in the hose 26. In addition to this, the cleaner body 28 includes a paper pack 30 and an exhaust port 34.

  FIG. 2 is an exploded view of the cyclone type dust collector 16. As shown in this figure, the dust collector 16 includes a swirler 18 and a dust collection chamber 20 made of a transparent member, and an exhaust guide 22 attached to the upper portion of the swirler 18 to form an air discharge path. It consists of

  The swirler 18 is formed with an intake guide 18 a at a portion connected to the shaft tube 14, so that intake air taken in from the floor suction tool 12 flows into the dust collector 16. Further, the revolving unit 18 is provided with a partition wall 18b having an opening 18c, and an engagement member 22c that contacts the partition wall 18b is formed on the outer peripheral surface of the exhaust guide 22.

  The engagement member 22c has an L-shaped cross section, and both ends of the exhaust guide 22 have tapered openings 22a and 22b. Although the length from the opening 22a to the end 22d of the engaging member 22c and the length from the opening 22b to the end surface 22e of the engaging member 22c are different, both the openings 22a and 22b are fitted into the handle tube 24. Are molded with the same taper shape.

  During normal use, the opening 22a is inserted into the swirler 18 through the opening 18c, the handle tube 24 is connected to the opening 22b, and the end 22d having an L-shaped cross section comes into contact with the partition wall 18b. On the other hand, when the opening 22b is inserted into the swirler 18 from the opening 18c and the handle tube 24 is connected to the opening 22a, the end face 22e having an L-shaped cross section comes into contact with the partition wall 18b.

  When the electric blower 32 of the vacuum cleaner 10 operates as shown in FIG. 4, the dust sucked together with the air from the floor suction tool 12 passes through the shaft tube 14 and enters the dust collector 16 from the inflow path 18a. enter. The intake air that has flowed into the dust collector 16 swirls at a high speed along the cylindrical inner wall portion of the swirler 18 as shown by the arrows in FIG. Due to the generated swirling airflow, centrifugal force acts on dust such as lint and cotton dust contained in the intake air, so that it moves outside in the dust collector 16. Since dust has a mass difference compared to air, it falls by its own weight and accumulates on the bottom surface of the dust collection chamber 20.

  On the other hand, since the working fluid in the vacuum cleaner 10 has no relative mass in the air, the centrifugal force does not act and is sucked from the opening 22a of the exhaust guide 22 and passes through the handle tube 24 and the hose 26. It is sucked into the cleaner body 28.

  The opening 22a is sufficiently separated from the bottom surface of the dust collecting chamber 20, and the dimension from the opening 22a to the end 22d where the engaging member 22c is in contact with the partition wall 18b is accumulated by sucking only air from which dust is separated. Molded to a length that does not suck in the dust.

  Inside the vacuum cleaner main body 28, small particles that could not be separated by the dust collector 16 are separated by the paper pack 30, and air from which dust has been completely removed passes through the electric blower 32 and is exhausted from the exhaust port 34 to the outside. Is done.

  The accumulated dust is discarded by removing the dust collecting chamber 20 from the swirler 18. Therefore, the dust collection chamber 20 is configured to be fitted in the lower part of the swirler 18 so that it can be easily detached from the swirler 18. These are fixed by an uneven member, a screw-like connection or the like so as not to be removed due to an impact during use.

  After the dust accumulated in the dust collection chamber 20 is discarded, fine dust still remains on the bottom surface of the dust collection chamber 20. In this case, as shown in FIG. 5, the exhaust guide 22 is attached in the opposite direction to that during normal use, the opening 22b is placed in the dust collector, the opening 22a is connected to the handle tube 24, and the electric blower 32 is installed. Make it work.

  At this time, the opening 22b is positioned near the bottom surface of the dust collection chamber 20, and a force larger than the suction force acting on the bottom surface of the dust collection chamber 20 when the floor surface is normally cleaned acts on the bottom surface of the dust collection chamber 20. Therefore, dust with fine particles receives a strong suction force and is removed from the dust collection chamber 20. Accordingly, the dimension from the opening 22b to the end face 22e where the engaging member 22c is in contact with the partition wall 18b is formed to a length that allows dust adhering to the vicinity of the bottom surface of the dust collecting chamber 20 to be sucked.

  The fine dust particles sucked in are accommodated in a paper pack 30 provided in the cleaner main body 28. The paper pack 30 containing the dust is removed from the cleaner body 28 and discarded. Therefore, it is possible to remove fine dust without washing the dust collection chamber 20 with water, and the amount of waste contained in the paper pack 30 of the cleaner body 28 is small, so there is no need for frequent replacement. Easy maintenance.

  In the embodiment of the present invention, an example in which a paper pack is provided in the main body of the vacuum cleaner is disclosed, but even if the paper pack is not provided in the main body of the vacuum cleaner, another paper pack is provided for maintenance. A vacuum cleaner may be prepared and connected to a dust collector, and fine dust accumulated on the bottom of the dust collecting chamber may be removed by suction.
