Description

  The present invention relates to a small-sized vacuum cleaner that facilitates dust disposal.

  Conventionally, as this type of vacuum cleaner, a filter (filter assembly) is swingably supported with respect to a dust collection box (dust collection case), and a stopper portion is provided on a side of the filter opposite to a hinge portion. It is known that a claw portion corresponding to a stopper portion is provided on the dust collection box, and the stopper portion and the claw portion are fitted to each other to close the opening (exhaust port) of the dust collection box with the filter. (For example, see Patent Document 1). Such a vacuum cleaner is configured such that by releasing the engagement between the stopper portion and the claw portion, the filter swings by gravity to open the opening of the dust collection box. Then, by opening the opening of the dust collecting box by the filter in this way, the dust accumulated in the dust collecting box can be discarded. Then, after discarding the dust, the filter is swung to engage the stopper with the claw of the dust collection box, so that the opening of the dust collection box is closed again by the filter.

Japanese Patent No. 5040453

  However, such a structure of the vacuum cleaner requires a claw portion to be provided in the opening of the dust collection box. Therefore, a small-sized vacuum cleaner such as a hand-held type vacuum cleaner is likely to be large in size, and is therefore adopted. There was a problem that it was difficult. In addition, when the opening of the dust collection box is closed by the filter, the filter must be touched with fine dust and thus is unsanitary.

  An object of the present invention is to solve the above problems and to provide a vacuum cleaner having a hygienic filter opening / closing mechanism without increasing the size even when employed in a small vacuum cleaner.

  The vacuum cleaner according to claim 1 of the present invention has a cleaner main body, a dust collecting case having an intake port and an exhaust port and detachable from the cleaner main body, and closing an exhaust port of the dust collecting case. In a vacuum cleaner having a filter assembly, the filter assembly includes a filter body, a lever protruding from the filter body, and a pivot provided between the filter body and the lever. The filter assembly is pivotally supported by the dust collecting case by the pivot so as to be swingable, and has urging means for urging the filter body in a direction to close the exhaust port.

  According to a second aspect of the present invention, in the vacuum cleaner according to the first aspect, the dust collecting case has a notch near the exhaust port, and the lever is located in the notch. .

  Also, in the vacuum cleaner according to claim 3 of the present invention, when the dust collecting case is attached to the cleaner body in claim 1 with the filter body closing the exhaust port. An abutting portion for abutting on the cleaner body is provided on the filter body.

And a seal portion that contacts the entire circumference of the vacuum cleaner.

  With the above configuration, the vacuum cleaner according to claim 1 of the present invention swings around a pivot by putting a finger on the lever with the dust collection case removed from the cleaner body. Thus, the exhaust port of the dust collecting case is opened, and dust can be discarded from the exhaust port. Then, by releasing the finger from the lever, the filter assembly swings in the opposite direction by the urging means without touching the filter body to which dust adheres, and the filter body closes the exhaust port again. So it is hygienic. In addition, since the filter body blocks the exhaust port by the urging means, the size of the vacuum cleaner can be reduced, and the size can be suppressed.

  The dust collecting case has a notch near the exhaust port, and the lever is located in the notch, so that the lever is prevented from projecting from the dust collecting case, and the vacuum cleaner is enlarged. Can be suppressed.

  Further, in a state where the filter main body closes the exhaust port, when the dust collecting case is attached to the cleaner main body, a contact portion that comes into contact with the cleaner main body is provided in the filter main body. Even if only the urging means is provided in the dust collection case, the exhaust port of the dust collection case can be reliably closed by the filter body.

  Further, the contact portion is provided in a cylindrical shape around the entire periphery of the ventilation portion in the filter body, and a seal portion in contact with the contact portion over the entire periphery is provided in the cleaner body, so that the airflow is reduced. Leakage can be suppressed and suction can be performed effectively.

Further, the dust collecting part 3 is detachably attached to the attaching part 11 of the cleaner body 2. A suction opening 12 is provided at the center of the mounting portion 11. The mounting portion 11 is provided with a short cylindrical rib 13 so as to surround the suction opening 12, and an annular seal portion 14 is mounted on the rib 13.

  The dust collecting unit 3 has a dust collecting case 21 and a filter assembly 31. The dust collecting case 21 has a case main body 22 and a mounting part 23. The case body 22 is formed in a substantially cylindrical shape with both ends opened. An opening at one end of the case main body 22 is an intake port 24. An opening on the other end side of the case body 22 is a mounting opening 25. The attachment portion 23 is attached to the attachment opening 25. Further, a notch 26 is formed at the other end of the case body 22. In addition, an exhaust port 27 is formed in the mounting portion 23, and a contact surface 28 is formed around the exhaust port 27. The notch 26 is provided near the exhaust port 27.

  The filter assembly 31 has a filter body 32 and a lever 33. A pivot 34 is provided between the filter body 32 and the lever 33. In addition, the filter body 32 and the lever 33 are formed integrally. Further, the filter body 32 is provided with a ventilation tube 35 which is a ventilation portion, and the filter body 36 is held in the ventilation tube 35. Further, the filter main body 32 is provided with an annular seal portion 37. The seal portion 37 contacts the contact surface 28 in a state where the filter main body 32 covers the exhaust port 27. The lever 33 is located in the notch 26 of the main body case 22. Further, the outer surface of the lever 33 is substantially flush with the outer surface of the main body case 22. Therefore, the protrusion of the lever 33 from the dust collecting case 21 can be suppressed, and the enlargement of the vacuum cleaner 1 can be suppressed. A short cylindrical contact portion 38 is provided on the mounting portion 11 side of the ventilation tube 35 so as to surround the periphery of the lower end of the ventilation tube 35. Then, in a state where the dust collecting unit 3 is attached to the cleaner body 2, the seal unit 14 comes into contact with the contact unit 38.

  The filter assembly 31 is pivotally supported by the pivot 34 so as to be swingable with respect to the mounting portion 23. Further, the filter assembly 31 is urged by a torsion coil spring 39 as an urging member so that the seal portion 37 abuts on the abutment surface 28 and the filter body 32 closes the exhaust port 27. .

  Next, the operation of the present embodiment will be described. First, the user attaches the dust collecting section 3 to the attaching section 11 of the cleaner body 2. In this state, the contact portion 38 of the filter body 32 is pressed by the seal portion 14. As a result, the sealing portion 37 of the filter body 32 of the filter assembly 31 comes into close contact with the contact surface 28 of the mounting portion 23 of the dust collecting case 21. Accordingly, the exhaust port 27 of the mounting portion 23 of the dust collecting case 21 is closed by the filter body 32 of the filter assembly 31. For this reason, an engaging mechanism for engaging the dust collecting case and the filter assembly as in the related art is not required, and the structure can be simplified to suppress the enlargement of the vacuum cleaner 1. Further, the seal portion 37 is in contact with the entire periphery of the contact surface 28, and the seal portion 14 is in contact with the entire periphery of the short cylindrical contact portion 38. It is possible to suppress airflow leakage from the ventilation tube 35 to the suction opening 12 and to effectively suck airflow.

  By operating a switch (not shown) provided on the cleaner main body 2, the electric blower is operated, and dust is sucked from the suction port 24 together with the suction airflow generated thereby. Then, the dust is separated from the dust-containing airflow by the filter body 36, and the separated dust is stored in the dust collecting unit 3. The suction airflow from which the dust is separated passes through the filter body 36 from the ventilation tube 35 that is a ventilation portion, and is sucked into the electric blower from the suction opening 12. Then, by operating the switch again, the electric blower stops. Thus, suction cleaning is performed.

  When the suction cleaning is completed, the dust collecting part 3 is removed from the mounting part 11 of the cleaner body 2 in order to discard the dust accumulated in the dust collecting part 3. At this time, since the filter body 32 of the filter assembly 31 blocks the exhaust port 27 with the torsion coil spring 39 serving as an urging member, dust does not spill from the exhaust port 27.

  Then, as shown in FIG. 4, the filter assembly 31 swings around the pivot 34 by pulling up the lever 33 with a finger against the biasing force of the torsion coil spring 39 on a trash can or the like. I do. As a result, the exhaust port 27 is released, and the dust accumulated from the exhaust port 27 can be discarded in a trash box or the like.

  When the finger is released from the lever 33, as shown in FIG. 3, the urging force of the torsion coil spring 39 causes the sealing portion 37 of the filter main body 32 to contact the contact surface 28 of the mounting portion 23 of the dust collecting case 21. Abut. That is, the urging force of the torsion coil spring 39 allows the filter main body 32 to close the exhaust port 27, so that the filter main body 32 does not touch the filter assembly 31 that is contaminated with dust or the like. 27 can be closed. Then, as described above, the filter body 32 is pushed by the seal part 14 by attaching the dust collecting part 3 to the attachment part 11 of the cleaner body 2, so that the exhaust port 27 is Is kept closed.

  As described above, according to the present invention, the cleaner body 2, the dust collecting case 21 having the intake port 24 and the exhaust port 27 and detachable from the cleaner body 2, and the exhaust port 27 of the dust collecting case 21 In the vacuum cleaner 1 having a filter assembly 31 that closes, the filter assembly 31 includes a filter body 32, a lever 33 that is provided to protrude from the filter body 32, and a gap between the filter body 32 and the lever 33. The filter assembly 31 is swingably supported by the dust collecting case 21 by the pivot 34, and the filter main body 32 is moved in a direction of closing the exhaust port 27. By having the torsion coil spring 39 as a biasing means for biasing, the lever 33 can be moved in a state where the dust collection case 21 is removed from the cleaner body 2. And swinging around the pivot 34, the exhaust port 27 of the dust collecting case 21 can be opened, and the dust can be discarded from the exhaust port 27. The filter assembly 31 swings in the reverse direction by the torsion coil spring 39 without touching the filter body 32 to which the filter body 32 is attached, so that the filter body 32 closes the exhaust port 27 again, which is more sanitary. Since the filter main body 32 closes the exhaust port 27 by the torsion coil spring 39, the size of the vacuum cleaner 1 can be reduced, and the structure can be simplified, and the vacuum cleaner 1 can be prevented from being enlarged. You can do it.

  Further, in the present invention, the dust collecting case 21 has a cutout portion 26 near the exhaust port 27 and the lever 33 is located in the cutout portion 26. It is possible to suppress the protrusion from the vacuum cleaner 21 and suppress the enlargement of the vacuum cleaner 1.
