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

  First, as a preparation for cleaning work, the dust collection cup 26 is attached to the attachment portion 33 of the cleaner body 13.

  At this time, the dust collecting cup 26 is in a state in which the bottom lid 83 is locked to the cup main body 81 by the locking means 135 to close the disposal opening 87, and the swivel separating unit 88 and the upper part of the cup main body 81 are disposed. Assume that the secondary filter unit 89 is attached.

  Then, gripping the cup gripping part 123 that is rotated with respect to the upper lid part 82 and raised to the gripping state, inserting the lower part of the cup body part 81 of the dust collecting cup 26 from the mounting opening 76, and pressing down, The bottom lid 83 at the bottom of the dust collection cup 26 and the vicinity of the lower end of the cup body 81 are fitted into the recess 66 of the mounting portion 33, and the dust collection cup 26 is fixed to the body case 25 of the cleaner body 13. In this state, the suction opening 85 of the dust collection cup 26 and the suction opening 72 of the wall 34 are in close contact with each other and are airtightly connected, and the exhaust opening 122 of the dust collection cup 26 and the opening 47 of the main body 32. Are closely connected and airtight. Thereafter, the user turns and holds the cup gripping portion 123 from the gripping state shown in FIG. 2 to the storage state shown in FIG.

  At this time, the protrusions 123c and 123c of the cup gripping portion 123 abut against the abutment portions 78a and 78a of the engagement and disengagement bodies 78 and 78 protruding from both sides of the handle 35, so that the engagement and disengagement bodies 78 and 78 are pivoted. Rotating against the bias about 78c, 78c, the locking portions 78b, 78b of the engagement / disengagement bodies 78, 78 project from the lower openings 79b, 79b and face the lower openings 79b, 79b. The dust collecting cup 26 is locked and fixed to the main body case 25 of the cleaner main body 13 by the engagement / disengagement mechanism 77 by being inserted into the locking recesses 124 and 124 of the dust collecting cup 26. Further, the operation button 136 is covered by the cup gripping portion 123, and the operation button 136 cannot be operated from the outside. Further, both sides of the cup body 81 of the dust collection cup 26 are exposed to the side of the cleaner body 13 through the exposure port 69.

  Further, the user connects the connecting pipe part 15 of the pipe part 12 to the main body suction port 71, and connects the extension pipe 18 to the hand operating part 17 on the distal end side of the hose body 16 as necessary. A floor brush 19 is connected to the tip side of the tube 18.

  The series of operations described above is not necessary when the dust collection cup 26 is attached to the attachment portion 33 in advance and the pipe portion 12 is connected to the main body suction port 71 in advance.

  Then, after the user pulls the power cord from the main body case 25 and connects it to an outlet (not shown) such as a wall surface, the user grips the grip portion 21 and operates a desired setting button 22. The control means 36 drives the electric blower 31 in an operation mode (strong mode, medium mode, weak mode, etc.) corresponding to the operation of the setting button 22.

  The negative pressure generated by driving the electric blower 31 acts on the dust collection cup 26 via the air passage portion 54, the opening 47 and the exhaust opening 122, and the suction opening 85 from the suction opening 85 of the dust collection cup 26 72, acting on the tube portion 12 via the main body inlet 71. Then, the user moves the floor brush 19 and the like back and forth on the surface to be cleaned, and sucks dust together with air by the action of negative pressure.

  The dust-containing air flows from the pipe portion 12 into the cup main body 81 of the dust collecting cup 26 through the main body suction port 71, the suction port 72, and the suction opening 85. At this time, by rectifying by the rectifying unit 93, the dust-containing air swirls around the outer periphery of the separation main body 96 along the inner peripheral surface of the cup main body 81, so that coarse dust such as cotton dust, which is relatively large dust, The dust is centrifuged and collected in the cup body 81.

  The dust-containing air from which the coarse dust has been separated is sucked into the swirl separation unit 88 from the ventilation opening 97. At this time, fine dust, which is relatively small dust, is collected by the filter 98 attached to the ventilation opening 97.

  Furthermore, when the dust-containing air passes upward through the swivel separation unit 88 and passes through the secondary filter 116, fine dust, which is even smaller dust, is collected. At this stage, almost all dust in the dust-containing air is collected in the dust collection cup 26.

  Thereafter, the air passes through the air passage 121, flows into the air passage portion 54 from the exhaust opening 122 through the opening portion 47, passes through the air passage portion 54 while being rectified, and is sucked into the electric blower 31. .

  Then, the air sucked into the electric blower 31 passes through the inside of the electric blower 31 to become exhaust air and is exhausted to the outside of the electric blower 31 and then to the outside of the main body case 25 through the exhaust port 43. And exhausted.

  When cleaning is completed, the control unit 36 stops the electric blower 31 when the user operates the setting button 22 for stopping.

  Further, for example, when the user visually observes the dust collecting cup 26 and determines that a predetermined amount or more of dust has accumulated, the cup gripping portion 123 of the dust collecting cup 26 is rotated with respect to the upper lid portion 82 to be in the gripping state. When this happens, the contact between the projecting parts 123c and 123c and the contact parts 78a and 78a of the engaging and disengaging bodies 78 and 78 is released, so that the engaging and disengaging bodies 78 and 78 are restored by the urging force of the urging means. And the locking portions 78b and 78b are retracted into the lower openings 79b and 79b and disengaged from the locking recesses 124 and 124, so that the cleaner main body 13 of the dust collecting cup 26 by the engagement / disengagement mechanism 77 is removed. The fixing to the main body case 25 is released, and the dust collecting cup 26 is pulled out from the mounting opening 76 by grasping the cup gripping portion 123 and removed from the main body case 25 of the cleaner body 13. Then, after transporting the dust collecting cup 26 to a disposal place such as a trash can, the operation button 136 is operated to release the locking of the bottom lid 83 by the locking means 135, and the cup body 81 is moved inside. The collected dust is discarded from the disposal opening 87.

  According to the embodiment described above, the dust collection cup 26 is fixed to the cleaner body 13 by setting the cup gripping portion 123 in the retracted state, and the dust collection cup is set by holding the cup gripping portion 123 in the gripping state. Compared with the configuration of the conventional example in which the state of the cup gripping portion 123 and the operation of the locking / disengaging mechanism 77 are different by including the engagement / disengagement mechanism 77 for releasing the fixing of the 26 to the vacuum cleaner body 13 By linking the engagement / disengagement mechanism 77 with the change in the state of 123, the workability of attaching / detaching the dust collecting cup 26 to / from the cleaner body 13 can be improved. In addition, since the cup gripping part 123 is located at the upper part of the cleaner body 13, although the user may mistakenly use the cup gripping part 123 instead of the handle 35 to lift the cleaner body 13, Even in this case, when the cup gripping portion 123 is lifted in the gripping state, the dust collecting cup 26 is surely detached from the cleaner main body 13, so that the cleaner main body 13 is not lifted accidentally by the cup gripping portion 123.

  Further, since the cup gripping portion 123 can be changed between a storage state and a gripping state by rotating, the dust collection cup 26 is fixed to the cleaner body 13 by setting the cup gripping portion 123 to the storage state, and the cup gripping is performed. The structure that releases the fixation of the dust collecting cup 26 to the cleaner body 13 can be easily formed by setting the portion 123 to the gripping state, and the upper lid portion where the cup gripping portion 123 is on the dust collecting cup 26 side when in the storage state Because it is almost the same as 82, it looks good.

  Further, the engagement / disengagement mechanism 77 is brought into contact with the protruding portion 123c in the vicinity of the base end portion 123a of the cup gripping portion 123 in a state where the cup gripping portion 123 is gripped and the dust collecting cup 26 is attached to the cleaner body 13. The dust collection cup 26 is fixed to the vacuum cleaner main body 13 by projecting in conjunction with the contact between the contact portion 78a and the contact portion 78a and the projecting portion 123c and engaging with the locking recess 124 of the dust collection cup 26. By configuring with the locking portion 78b, the dust collection cup 26 can be fixed in the vicinity of the base end portion 123a serving as the rotation axis of the cup gripping portion 123, so that the dust collection cup 26 can be fixed more stably, The dust collection cup 26 can be fixed at the same time in the vicinity of both base end portions 123a and 123a only by putting the cup gripping portion 123 in the retracted state. Can be released simultaneously, and operability is good.

  And it is located in front of the dust collection cup 26 attached to the attachment part 33 of the main body case 25 of the vacuum cleaner body 13, and the suction opening 85 of the dust collection cup 26 and the outside are connected in an airtight manner by the front seal member 75. It is located behind the dust collection cup 26 attached to the suction port 72 and the attachment part 33 of the main body case 25 of the vacuum cleaner main body 13, and the downstream side of the dust collection cup 26 and the suction side of the electric blower 31 are rear seals. An opening 47 that is airtightly connected by the member 56 is provided, and the engagement / disengagement mechanism 77 is disposed on both sides of the dust collection cup 26, thereby forming a cross shape by the left and right fixed positions and the front and rear seal positions. That is, the dust collection cup 26 is stably attached to the cleaner body 13 by setting the fixed position and the seal position of the dust collection cup 26 to be mutually orthogonal to the center position of the dust collection cup 26 in plan view.
