Description

  The present invention relates to a vacuum cleaner including a filter that is rotatably mounted in the middle of a suction air passage provided in a vacuum cleaner body, for example.

  2. Description of the Related Art Conventionally, an electric vacuum cleaner in which a dust collecting container is detachably provided on a vacuum cleaner body is known (see Patent Document 1).

  Such a vacuum cleaner includes a vacuum cleaner body having a dust container chamber formed therein, a dust container that is detachably attached to the dust container chamber, and an electric blower provided downstream of the dust container chamber. And a pleated filter that is a secondary filter that is detachably attached to the rear opening of the dust collecting container, and a dust removing means that shakes off dust adhering to the pleated filter. Note that the pleats of the pleat filter extend in the vertical direction.

  This dust removing means is arranged so that the ring can freely rotate at a position facing the pleat filter, and provided with a protrusion abutting against the pleat filter on the ring, and the ring is rotated when the cord reel winds up the power cord. As the ring rotates, the projection moves over the pleat peaks of the pleat filter, thereby giving vibration to the pleat filter and dropping dust adhering to the pleat filter.

  However, in such a vacuum cleaner, when the projection of the ring is moving on the upper position of the pleat filter, the dust dropped from the upper portion of the pleat filter extends in the vertical direction. However, there is a problem that the dust adheres again at the lower part of the pleat.

  Therefore, the protrusion is fixed to the lower side of the pleat filter and the pleat filter is rotatably provided, has a discharge port for discharging dust, and receives the dust falling from the pleat filter, and collects in the dust receiver. It is conceivable to provide a blade for discharging the dust to the discharge port.

By rotating the pleated filter, the pleated filter vibrates the pleated filter with a protrusion and drops the dust. By rotating the pleated filter, the blade is moved over the dust receiving part to collect the dust accumulated on the dust receiving part. It is discharged to the outlet.

  However, in such a vacuum cleaner, when the electric blower is driven, there is a problem that dust discharged to the discharge port is sucked from the discharge port and is again attached to the pleated filter.

  An object of the present invention is to provide a vacuum cleaner in which the dust discharged to the discharge port is not sucked from the discharge port and attached to the filter again even when the electric blower is driven.

In order to achieve the above-mentioned object, the invention of claim 1 is characterized in that a filter rotatably provided in the middle of a suction air path from a dust suction port for sucking dust to a suction opening of an electric blower of the main body of the cleaner, A driving means for rotating; a dust removing means for dropping dust adhering to the filter by the rotation of the filter; a dust receiving part for receiving the dust dropped by the dust removing means; and the dust receiving part on the dust receiving part by the rotation of the filter. A vacuum cleaner comprising a discharge member that moves and discharges the dust in the dust receiving portion to a discharge port provided in the dust receiving portion,

In FIG. 17, reference numeral 200 denotes a control device that controls the electric blower 24 and the motor M based on the operation of the operation switch 13a (see FIG. 1) of the operation unit 13A and the detection signal of the micro switch S1.
[Operation]
Next, operation | movement of the vacuum cleaner comprised as mentioned above is demonstrated.

  First, as shown in FIG. 2, the dust collection unit 50 is mounted in the dust collection unit chamber 22 of the cleaner body 11, and the dust collection hose 12 is connected to the connection port 11 </ b> A of the cleaner body 11 as shown in FIG. 1. At the same time, the suction port body 15 is connected to the hand operation tube 13 via the extension tube 14.

  Then, a power plug (not shown) is connected to the outlet. At this time, when the micro switch S1 does not detect the blade 303 of the blade body 300, that is, when the blade 303 does not block the discharge port 86A of the dust receiving portion 86, the motor M is driven and the pleated filter of the filter portion 80 The body 100 rotates. When the pleated filter body 100 is rotated, the blade 303 of the blade body 300 is slidably moved on the dust receiving portion 86, and when the blade 303 comes to a position closing the discharge port 86A of the dust receiving portion 86, the micro switch S1 is turned on. The blade 303 is detected, and the control device 200 stops the driving of the motor M by this detection.

  During the sliding movement of the blade 303, dust accumulated in the dust receiving portion 86 is swept out to the discharge port 86A, and discharged from the discharge port 86A into the separation chamber portion 54 of the dust separation portion 52 through the communication passage 59. Is done.

  While the motor M is being driven, that is, while the blade 303 is moving to the position where the discharge port 86A is blocked, the electric blower 24 is not driven even if the switch 13a of the operation unit 13A of the hand operation tube 13 is operated. Thereby, the dust discharged to the separation chamber portion 54 of the dust separation portion 52 is prevented from being sucked from the discharge port 86A and attached to the pleated filter 104 again.

  When the micro switch S1 of the dust collecting unit 50 detects the blade 303 of the pleated filter body 100, that is, when the blade 303 blocks the discharge port 86A of the dust receiving portion 86, the operation portion 13A of the hand operation tube 13 is operated. When the switch 13a is operated, the electric blower 24 is driven.

  By driving the electric blower 24, air is sucked from the suction opening 24 </ b> A of the electric blower 24, a negative pressure acts in the storage case 81 of the dust collection unit 50 through the connection air passage portion 25, and the suction air passage It acts on the inside of the dust collecting case 70K and the separation chamber portion 54 of the dust separation portion 52 via the portion 56. The negative pressure acts on the dust collecting hose 12, the extension pipe 14 and the suction port body 15 via the guide air duct tube 57, and dust is sucked together with air from the suction port body 15.

  The sucked dust and air are sucked into the suction connection port 57a of the dust collecting unit 50 through the extension pipe 14 and the dust collecting hose 12. The dust and air sucked into the suction connection port 57a are introduced into the separation chamber portion 54 of the dust separation portion 52 through the guide air passage tube 57, and rotate counterclockwise in FIG. I will do it.

  Then, dust and a part of the air are separated by this rotation, and the separated air passes through the net filter NF1 of the dust separating means 55 shown in FIG. It is sucked into 81.

  On the other hand, the dust and air that have not been separated are introduced into the communication case portion 72 of the dust collection portion 70 from the introduction opening 53A of the separation chamber portion 54 by the rotation thereof. The introduced dust and air are sucked into the dust collection chamber 73 through the communication path 71 of the communication case portion 72, and the dust is collected in the dust collection chamber 73.

  The air sucked into the dust collection chamber 73 is sucked into the suction air passage portion 56 through the filter F1 and the connection opening 75, and further sucked into the storage case 81 of the filter portion 80.

  The air sucked into the storage case 81 passes through the pleated filter 104 of the pleated filter body 100 and is sucked into the connection air passage portion 25 of the cleaner body 11 and further sucked into the suction opening 24A of the electric blower 24.

  Incidentally, since the blade 303 of the blade body 300 closes the discharge port 86A of the dust receiving portion 86 of the storage case 81, the dust in the separation chamber portion 54 of the dust separation portion 52 is communicated from the discharge port 86A via the communication path 59. This prevents the dust from adhering to the pleated filter 104 again.

  Air sucked into the suction opening 24A of the electric blower 24 passes through the electric blower 24 and is exhausted from the exhaust port 20H of the cleaner body 11 shown in FIG.

  When the cleaning is completed, the operation of the electric blower 24 is stopped by operating the operation switch 13a of the operation unit 13A. When driving of the electric blower 24 is stopped, the control device 200 of FIG. The drive gear 110 is rotated by driving the motor M, and the pleated filter body 100 is rotated.

  Due to the rotation of the pleated filter body 100, the protrusion 88 of the front wall portion 84 of the storage case 81 hits the peak portion of the pleat filter 104 and gets over the peak portion with the rotation. Each time the projection 88 gets over the mountain, vibration is applied to the pleated filter 104, and dust attached to the pleated filter 104 is shaken off. This dust accumulates in the dust receiving part 86 of the storage case 81.

  Since the protrusion 88 is provided below the center of rotation of the pleated filter body 100, a large vibration is applied to the pleated filter 104 in the lower portion of the pleated filter body 100. For this reason, dust is shaken off from the lower pleat filter 104 and falls to the dust receiving portion 86 as it is, and it does not adhere to the pleat filter 104 again during the fall, and therefore it is efficient. Dust can be dropped.

  On the other hand, the blade body 300 rotates together with the pleated filter body 100, and the sliding contact portion 303B of the blade 303 of the blade body 300 slides and moves on the upper surface of the dust receiving portion 86 of the storage case 81 as shown in FIG. Go. Due to the sliding movement of the sliding contact portion 303B of the blade 303, the dust accumulated in the dust receiving portion 86 moves along the peripheral surface of the dust receiving portion 86 and is swept out to the discharge port 86A of the dust receiving portion 86. To go. The dust swept out to the discharge port 86 </ b> A is discharged into the separation chamber portion 54 of the dust separation portion 52 through the communication path 59.

  When the pleated filter body 100 rotates, for example, once, and the blade 303 comes to a position where it closes the discharge port 86A of the dust receiving portion 86 as shown by a chain line in FIG. 16, the microswitch S1 detects the blade 300, and the control device 200 Stops driving the motor M. Accordingly, the rotation of the pleated filter body 100 is stopped at a position where the blade 303 blocks the discharge port 86A of the dust receiving portion 86.

  In this embodiment, since the three blades 303 are provided, the driving of the motor M is stopped when the microswitch S1 detects the blade 303 three times.

  When the switch 13a of the operation unit 13A of the hand operation tube 13 is operated again before the blade 303 reaches the position for closing the discharge port 86A of the dust receiving unit 86, the control device 200 does not drive the electric blower 24. Thereby, the dust discharged to the separation chamber portion 54 of the dust separation portion 52 is prevented from being sucked from the discharge port 86A and attached to the pleated filter 104 again.

  Further, when the power plug is pulled out from the outlet before the blade 303 of the blade body 300 comes to the position of closing the discharge port 86A of the dust receiving portion 86, the motor before the blade 300 closes the discharge port 86A of the dust receiving portion 86 is removed. Although the driving of M is stopped and the discharge port 86A is not blocked by the blade 300, as described above, when the power plug is connected to the outlet, the motor M is driven to rotate the pleated filter body 100, thereby discharging Since the outlet 86A is closed by the blade 303 and the electric blower 24 is driven thereafter, the problem that the dust discharged to the separation chamber portion 54 of the dust separation portion 52 is sucked from the discharge port 86A is prevented.

  When the pleated filter 104 is clogged due to long-term use, the pleated filter 104 is cleaned.

  In this cleaning, first, the lid 21 of the cleaner body 11 is opened, and the dust collection unit 50 is lifted. By this lifting, the drive gear 110 is disposed at a position below the rotation center position of the gear 107 of the pleated filter body 100, so that the drive gear 110 does not get in the way and the gear 107 of the pleat filter body 100 is driven. The gear 110 is disengaged. For this reason, the dust collection unit 50 can be easily removed from the dust collection unit chamber 22 of the cleaner body 11.

  When the dust collection unit 50 is taken out from the dust collection unit chamber 22, the pleat filter 104 of the pleated filter body 100 of the dust collection unit 50 is cleaned. At this time, the dust collecting unit 70 may be removed.

  When the cleaning of the pleated filter 104 is completed, if the dust collecting unit 50 is inserted into the dust collecting unit chamber 22 of the cleaner body 11 from above, the drive gear 110 is below the rotational center position of the gear 107 of the pleated filter body 100. With the arrangement, the gear 107 of the pleated filter body 100 meshes with the drive gear 110 without the drive gear 110 getting in the way, and the dust collection unit 50 is mounted in the dust collection unit chamber 22.

  As described above, when the dust collection unit 50 is inserted from above the dust collection unit chamber 22, the mounting is completed, so that the mounting can be easily performed.

  When the dust collected in the dust collection unit 70 is discarded, it is not necessary to remove the dust collection unit 50. Therefore, it is only necessary to open the lid 21 of the cleaner body 11 and remove only the dust collection unit 70 from the dust collection unit 50. . Then, the cover plate 77 of the dust collection unit 70 is opened to discard the dust accumulated in the dust collection chambers 73 and 73A.
