The floor brush 114, the extension pipe 113 and the hose body 111 constitute a pipe portion 117 for sucking dust from the floor surface by driving the electric blower 7.

  Next, the operation of the above embodiment will be described.

  First, when cleaning is started, the lid 3 is opened, and the mouth frame 25 of the paper pack 21 in a state where the bag body 26 is folded is inserted between the groove portion 32 of the holder main body 28 of the paper pack holder 22 on the insertion port 34 side. And the paper pack 21 is held in the paper pack holder 22.

  In this state, the operator holds the handle 29, attaches the paper pack holder 22 holding the paper pack 21 from the upper side of the dust collection chamber 10, and closes the lid 3.

  At this time, the lower surface of the lid 3 pushes down the handle 29 of the paper pack holder 22 against the bias, and the handle 29 is fitted into the fitting recess 35 of the holder main body 28 to be in a substantially parallel state. At the same time, the packing 89 of the lid 3 is pressed against the opening frame 25 of the paper pack 21, the insertion tube portion 88 is inserted into the pack opening 24 of the paper pack 21, and the downstream side surface of the groove portion of the pleat filter 98 is dust The outside air introduction port 55 and the introduction opening 101 are airtightly connected with the removal mechanism 65.

  Then, the operator inserts and connects the connecting pipe 111a of the hose body 111 to the main body suction port 87 of the lid body 3 and sequentially connects the extension pipe 113 and the floor brush 114 to the distal end side of the hose body 111. .

  Further, when the operator grips the grip portion 115 and sets the operation mode of the electric blower 7 by the setting button 116 and starts the operation of the electric vacuum cleaner, the electric blower 7 is driven in the set operation mode, and the floor brush 114 is moved back and forth on the floor surface, and dust on the floor surface is sucked from the front end side of the floor brush 114.

  In this suction state, the introduction opening / closing valve 73 is closed by the drive mechanism 52 and the communication opening / closing valve 74 is opened.

  Then, the air sucked from the front end side of the floor brush 114 by the action of the negative pressure by driving the electric blower 7 is sucked into the main body suction port 87 through the extension pipe 113 and the hose body 111, and is inserted into the insertion cylinder portion 88. The air is branched into the paper pack 21 side and the pleated filter 98 side via the upper air passage 94, and the branched air merges at the space communication port 61 and is then sucked into the electric blower 7 from the communication tube portion 54. In addition, the air passes through the electric blower 7 to become exhaust air and is exhausted from the exhaust hole 18.

  Specifically, out of the dust contained in the air, coarse dust travels straight through the insertion tube portion 88 due to inertia and is collected in the paper pack 21. Fine dust contained in the air that has passed through the paper pack 21 is The air collected by the filter 63 and collected by the dust is sucked into the electric blower 7 from the lower space 58 through the communication tube portion 54. On the other hand, among the dust contained in the air, fine dust is branched to the ventilation opening 92 side at the insertion tube portion 88 and collected by the mesh filter 93, and the fine dust that has passed through the mesh filter 93 is The air that flows into the space 96 from the upper air passage 94 and is collected by the pleated filter 98, and the air in which the dust is collected flows from the upper space 59 to the lower space 58 through the space communication port 61. It flows in and is sucked into the electric blower 7 from the communication tube portion 54.

  When the cleaning is finished, when the operator stops the operation mode of the electric blower 7 with the setting button 116, the control unit operates the drive mechanism 52 via the motor 71 to drive the dust removal mechanism 65. Then, the pleat filter 98 is flipped left and right, the inlet opening / closing valve 73 is opened, and the communication opening / closing valve 74 is closed.

  For this reason, the fine dust collected by the pleat filter 98 is dropped by the operation of the dust removing mechanism 65, and the air in the electric blower chamber 8 flows from the outside air inlet 55 into the space 96 through the inlet opening 101. After passing from the upper side to the lower side of the upstream side of each groove portion of the pleated filter 98, the lower side air passage 95, the insertion cylinder part 88, the paper pack 21, the lower space part 58 and the communication cylinder part 54 are passed. By being sucked into the electric blower 7, fine dust collected by the pleated filter 98 and dust removed from the pleated filter 98 by the dust removing mechanism 65 are collected in the paper pack 21.

  And a control means stops the electric blower 7 after predetermined time passes.

  When dust of a predetermined amount or more is collected in the paper pack 21, the lid 3 is opened and the paper pack 21 is discarded.

  At this time, as shown in FIG. 8, when the lid 3 is opened, the handle 29 pressed against the holder main body 28 by the lid 3 is restored by the urging of the torsion spring to pack against the holder main body 28. It rises so as to form an acute angle toward the opening direction of the opening 24, and the pack opening 24 of the paper pack 21 is visible from above.

  The operator holds the handle 29 and pulls up the paper pack holder 22 together with the paper pack 21, and removes the paper pack holder 22 holding the paper pack 21 from the dust collection chamber 10.

  In this state, the handle 29 is inclined at an acute angle with respect to the holder main body 28 toward the insertion port 34. Therefore, when the handle 29 is gripped, the insertion port 34 side of the paper pack holder 22 is relatively slightly above the upper side. The paper pack 21 is held by the paper pack holder 22 with the pack opening 24 facing upward.

  When the operator pushes the button 47 toward the holder main body 28 with the thumb of the hand holding the handle 29 at the upper part of the trash can, as shown in FIGS. 2 (a) and 2 (b) The main part 43a moves downward against the bias of the spring, and the tip of the clamp part main body 43a moves from the upper side to the curved surface part 37f of the clamp body 37 in the horizontal direction of the holder main body 28 (paper pack holder 22). By abutting in an inclined manner toward the center side, the upper side of the rotation axis 37d, 37d of the clamp body 37 is rotated in the direction of the opening 31, and the claw portion 37a below the rotation axis 37d, 37d. , 37a move in a direction away from the claw portion 36.

  As a result, the groove 32 is opened and the holding of the paper pack 21 by the paper pack holder 22 is canceled, and the paper pack 21 falls into the trash box due to its own weight and is discarded.

  In this way, the paper pack 21 can be easily held in the groove portion 32 by sliding the paper pack 21 with respect to the groove portion 32 of the holder body 28, and after the paper pack 21 is held in the groove portion 32, By operating the clamp body 37 that forms one of the groove portions 32 by pressing a button 47 in this case, the claws 37a and 37a of the clamp body 37 that forms the groove portion 32 are moved to these claws. When the paper pack 21 is released by operating in a direction away from the claw portions 36 and 36 facing the portions 37a and 37a, the groove portion 32 is opened and the paper pack 21 is removed from the holder body 28 by its own weight. Therefore, the paper pack 21 can be easily removed and discarded without directly touching the paper pack 21.

  Further, the paper pack 21 is attached to the paper pack holder 22 by sliding from the insertion port 34, and is removed in the direction intersecting the insertion direction by the operation of the clamp body 37, that is, the paper pack 21 is attached to the paper pack holder 22. Since the direction and the removal direction are different, the paper pack 21 can be easily attached to the paper pack holder 22 and can be easily discarded without touching the paper pack 21 and dust.

  Further, by providing a handle 29 for gripping on the holder main body 28 and providing a button 47 for operating the clamp body 37 on the handle 29, it becomes possible to operate the button 47 with a hand gripping the handle 29, for example, Grasp the handle 29 from the dust collection chamber 10 and remove the paper pack holder 22 together with the paper pack 21, transport it as it is to a trash can, etc., and operate the button 47 with the hand that grabbed the handle 29 to discard the paper pack 21. From the removal of the paper pack 21 to the disposal can be performed with one hand, and the usability is improved.

  Since the operation of the button 47 can be transmitted to the clamp body 37 by the clamp portion 43 with a predetermined angle width in the rotation angle of the handle 29 with respect to the holder body 28, the handle 29 is set at various angles with respect to the holder body 28. Even when gripped, the clamp body 37 can be operated by operating the button 47 so that the paper pack 21 can be easily removed, improving usability. In addition, since the distal end portion of the clamp portion 43 is exposed from the base opening 45a, the operation of the button 47 is clamped by the clamp portion 43 by setting the opening size of the covering member opening 39c facing the distal end portion of the clamp portion 43. The predetermined angular width that can be transmitted to the body 37 can be easily set to an arbitrary angle.

In the above embodiment, the paper pack holder 22 is configured to release the holding of the paper pack 21 by operating a holding portion that forms at least one of the groove portions 32 to which the paper pack 21 is slid and attached. Any other configuration is possible.

Also, the details of the electric vacuum cleaner is not limited to the above configuration, for example, it may be a conventional paper bag type vacuum cleaner, As the vacuum cleaner is not limited to the canister type, for example, autonomous If the lid 3 is located on the upper side and the paper pack 21 is attached to the dust collecting chamber 10 from the upper side, such as a vacuum cleaner of the type (robot type) or a handy type, it can be used correspondingly.
