  About the vacuum cleaner 100 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

A state in which the dust collector 2 is attached to the cleaner body 1, that is, a first recess 14 a formed in the body handle 14 of the cleaner body 1 and a claw portion 34 formed in the handle 23 of the dust collector 2 Are engaged and the handle 23 of the dust collector 2 is in the retracted state, the user holds the handle 6 and starts the operation of the vacuum cleaner 100. Occurs and suction force is generated. When the user moves the suction tool 3 on the surface to be cleaned in this state, dust on the surface to be cleaned is sucked together with the suction air from the suction tool 3. Suction air containing dust sucked from the suction tool 3 flows into the cleaner body 1 through the extension pipe 4 and the hose 5 from the air inlet 1a. The suction air including dust that has flowed into the cleaner body 1 passes through a communication air passage (not shown) formed inside the cleaner body 1, and the inlet 15 a formed at the rear portion of the dust collector 2. Flows into the dust collector 2.

  The air containing dust that has flowed into the dust collector 2 flows into the centrifugal separation space 2a formed by the inner surface of the dust collector main body 15 and the primary filter 16, and a swirl flow generated in the centrifugal separation space 2a. As a result, the dust and air including coarse dust and fine dust are centrifuged. The dust centrifuged in the centrifugal separation space 2a passes through the dust passage 2c formed between the first extension 19 and the second extension 20 and the inner surface of the dust collector main body 15, The dust is accumulated in the dust accumulation space 2 b formed in the lower part of the dust collector 2 by the inner surface of the dust collector main body 15, the first extension 19 and the lower lid 21.

  Here, as shown in FIG. 5, in the present embodiment, since the width H1 of the dust passage portion 2c is formed to be smaller than the width H2 of the centrifugal separation space portion 2a, the centrifugal separation space portion It is possible to increase the flow velocity of the air flowing from 2a into the dust accumulation space 2b, and to generate a pressing force from the centrifugal separation space 2a toward the dust accumulation space 2b. Therefore, the dust accumulated in the dust accumulation space 2b can be compressed, and the dust accumulated in the dust accumulation space 2b can be prevented from returning to the centrifugal separation space 2a.

  Further, the air that has flowed into the dust storage space 2b together with the dust flows from the dust storage space 2b to the centrifugal separation space 2a by the suction force of the electric blower 9, but at this time, the air is stored in the dust storage space 2b. Dust may be guided to the centrifugal separation space 2a by the flow of air flowing from the dust accumulation space 2b to the centrifugal separation space 2a and may adhere to the primary filter 16. Therefore, in the present embodiment, the first extension portion 19 is formed in the lower portion of the primary filter 16, and the second extension portion 20 is provided between the primary filter 16 and the first extension portion 19. By forming the dust, the dust flowing back from the dust storage space portion 2b to the centrifugal separation space portion 2a together with the air flowing into the dust storage space portion 2b is separated from the primary filter 16, that is, the swiveling of the centrifugal separation space portion 2a. The dust that is guided to the region where the flow velocity of the airflow is high and returns from the dust accumulation space portion 2b to the centrifugal separation space portion 2a is transferred to the dust accumulation space portion 2b together with the dust flowing from the centrifugal separation space portion 2a to the dust accumulation space portion 2b. It is possible to prevent the dust accumulated in the dust accumulation space 2b from returning to the centrifugal separation space 2a and adhering to the primary filter 16. In the present embodiment, the first cylinder 19 is provided between the first inclined portion 19a and the vertical portion 19b of the first extending portion 19 formed at the lower portion of the primary filter 16 and the second cylindrical portion 19e. A portion 19c is provided, and a second extending portion 20 is formed between the primary filter 16 and the first extending portion 19, and the air flowing into the dust accumulation space portion 2b flows to the centrifugal separation space portion 2a. By increasing the length of the flow path, it is possible to prevent the dust accumulated in the dust accumulation space portion 2b from flowing into the centrifugal separation space portion 2a together with the air flowing from the dust accumulation space portion 2b to the centrifugal separation space portion 2a. ing.

The air from which the dust has been centrifuged in the centrifugal separation space 2a passes through the primary filter 16, and then passes through the secondary filter 18, so that it is not centrifuged in the centrifugal separation space 2a, and the primary filter 16 together with the air. Dust that has passed through the secondary filter 18 is collected. Only air that does not contain dust passes through the secondary filter 18 and is discharged from the outlet 22 a of the dust collector 2 to the outside of the dust collector 2. The air exhausted from the dust collector 2 flows into the cleaner body 1 and, through an intake passage (not shown) formed in the cleaner body 1, an intake port ( It flows into the inside of the electric blower 9 from not shown. And the air which flowed into the inside of the electric blower 9 is discharged to the outside of the electric blower 9, and then
It is discharged to the outside of the cleaner body 1 from an exhaust port (not shown) formed in the cleaner body 1 through the electric blower chamber 10.

  The dust collected by the secondary filter 18 is given vibration from the drive unit 25 to the dust removing unit 24 provided above the secondary filter 18 when the electric blower 9 is stopped. It is peeled off. The dust peeled off from the secondary filter 18 passes through a space inside the primary filter mounting frame 17 and is guided to the lower side of the primary filter 16. The dust guided to the lower side of the primary filter 16 is guided to the inside of the second cylindrical portion 19e by the second inclined portion 19d formed in the first extending portion 19, and the second cylindrical portion 19e. Accumulated inside.

  When the user throws away the dust accumulated in the dust collector 2, the user operates the operation unit 38 provided at the front upper portion of the dust collector 2, that is, the front portion of the upper cover 22 of the dust collector 2. , The engagement between the third recess 36 of the handle 23 and the holding portion 37, and the first recess 14 a provided in the main body handle 14 of the cleaner body 1 and the handle 23 of the dust collector 2. By releasing the engagement with the claw portion 34, the dust collecting device 2 is removed from the cleaner body 1, and the dust accumulated in the dust collecting device 2 is discarded.

  Specifically, in a state where the dust collector 2 is attached to the cleaner body 1 at a predetermined angle, the first recess 14a formed in the body handle 14 of the cleaner body 1 and the dust collector 2 A claw portion 34 formed on the handle 23 is engaged, and a third recess 36 provided on the handle 23 of the dust collector 2 and a holding portion 37 provided on the upper lid 22 of the dust collector 2 Is engaged against the biasing force of the torsion spring 33, so that the dust collector 2 is held by the cleaner body 1. In this state, when the user moves the operation unit 38 to the inside of the upper lid 22 against the urging force of the coil spring 39 in order to discard the dust accumulated in the dust collector 2, the operation of the operation unit 38 is performed. In conjunction with this, the holding portion 37 moves to the inside of the upper lid 22, and the engagement between the third concave portion 36 provided in the handle 23 and the holding portion 37 is released. When the engagement between the third recess 36 and the holding portion 37 is released, the handle 23 is rotated in the direction from the retracted state to the inverted state by the biasing force of the torsion spring 33, and the handle 23 is rotated. In conjunction with this, the engagement between the first recess 14 a formed in the main body handle 14 of the cleaner body 1 and the claw portion 34 formed at the end of the handle 23 is released, and the handle 23 is rotated. In conjunction with this, the claw portion 34 comes into contact with the main body handle 14, and the dust collector 2 is pushed up in a direction away from the cleaner main body 1. In this state, the user can remove the dust collector 2 from the cleaner body 1 by holding the handle 23 and lifting the dust collector 2 above the cleaner body 1.

  At this time, since the torsion spring 33 is configured to rotate coaxially with the rotation shaft portion 23c of the handle 23 when the handle 23 rotates, an excessive load is applied to the torsion spring 33 when the handle 23 rotates. Can be sufficiently prevented, the handle 23 can be easily rotated by the biasing force of the torsion spring 33, and the torsion spring 33 can be sufficiently prevented from being deformed by an excessive load. Therefore, the torsion spring 33 can be sufficiently prevented from deteriorating due to an excessive load, and the handle 23 can be reliably rotated by the urging force of the torsion spring 33.

Further, when the rotation angle of the handle 23 is less than a predetermined angle, only one end of the torsion spring 33 fixed to the handle 23 is linked to the rotation of the handle 23 and the rotation shaft portion 23c of the torsion spring 33 is rotated. And the other end of the torsion spring 33 is brought into contact with the rib body 22d inside the upper lid body 22 so that the rotation is restricted. Therefore, the urging force of the torsion spring 33 can be reliably transmitted to the handle 23, and the urging force of the torsion spring 33 can reliably rotate the handle 23 in the direction from the housed state to the inverted state. Further, the torsion spring 33 is configured such that one end of the torsion spring 33 fixed to the handle 23 is interlocked with the rotation of the handle 23 when the rotation angle of the handle 23 exceeds a predetermined angle. And the other end of the torsion spring 33 inserted into the upper lid 22 and the rib body 22d are released, and the other end of the torsion spring 33 is interlocked with the rotation of the handle 23. It is configured such that both ends of the torsion spring 33 rotate coaxially with the rotation shaft 23c in conjunction with the rotation of the handle 23 along the groove 22c. Yes. Therefore, an excessive load is not applied to the torsion spring 33 when the handle 23 is rotated by a predetermined angle or more, so that the torsion spring 33 is not deformed, and the torsion spring 33 is deteriorated by the deformation of the torsion spring 33. This can be sufficiently prevented, and the handle 23 can be more reliably rotated by the biasing force of the torsion spring 33.

  Here, in the present embodiment, when the rotation angle of the handle 23 is less than the angle at which the torsion spring 33 is in a no-load state, only one end of the torsion spring 33 fixed to the handle 23 is attached to the handle 23. In conjunction with the rotation, it rotates coaxially with the rotation shaft 23c, and the other end of the torsion spring 33 inserted into the upper lid body 22 is brought into contact with the rib body 22d to restrict the rotation. When the rotation angle of the handle 23 is equal to or greater than the angle at which the torsion spring 33 is in a no-load state, one end of the torsion spring 33 rotates coaxially with the rotation shaft portion 23c in conjunction with the rotation of the handle 23.

The handle 23 can be reliably rotated by the biasing force of the torsion spring 33. Further, when the rotation angle of the handle 23 becomes equal to or greater than the angle at which the torsion spring 33 is in a no-load state, the torsion spring 33 is released from the contact between the other end of the torsion spring 33 and the rib body 22d. Since both ends of the torsion spring 33 are rotated coaxially with the rotation shaft portion 23 c in conjunction with the rotation of the handle 23, the user holds the handle 23 and removes the dust collector 2 from the cleaner body 1. In this case, even if the rotation angle of the handle 23 is equal to or greater than an angle at which the torsion spring 33 is in a no-load state, an excessive load is not applied to the torsion spring 33 and the torsion spring 33 is deformed.

An excessive load on the spring 33 can be sufficiently prevented, and the handle 23 can be easily rotated by the urging force of the torsion spring 33, and an excessive load is applied to the torsion spring 33. Deformation of 33 can be sufficiently prevented. Therefore, the torsion spring 33 can be sufficiently prevented from deteriorating due to an excessive load, and the handle 23 can be reliably rotated by the urging force of the torsion spring 33.

  In the present embodiment, only one end of the torsion spring 33 is fixed to the handle 23, and the other end of the torsion spring 33 abuts on the dust collector 2 when the handle 23 is in the retracted state. When the handle 23 is rotated from the retracted state to the inverted state, the handle 23 is configured to rotate coaxially in conjunction with the rotation of the handle 23, so that the urging force of the torsion spring 33 is reliably transmitted to the handle 23. The handle 23 can be reliably rotated from the stored state to the inverted state. Further, when the handle 23 is rotated, an excessive load is applied to the torsion spring 33, and the torsion spring 33 can be sufficiently prevented from being deformed. The handle 23 can be more reliably rotated by the biasing force of the spring 33.

  Furthermore, in the present embodiment, when the rotation angle of the handle 23 is less than the angle at which the torsion spring 33 is in a no-load state, the torsion spring 33 is configured so that one end of the torsion spring 33 is rotated by the handle 23. When the other end of the torsion spring 33 is in contact with the dust collector 2 and the rotation angle of the handle 23 is equal to or greater than the angle at which the torsion spring 33 is in a no-load state, Since both ends of the torsion spring 33 are configured to rotate in conjunction with the rotation of the handle 23, when the rotation angle of the handle 23 is less than the angle at which the torsion spring 33 is in a no-load state, The urging force of the torsion spring 33 can be reliably transmitted to the handle 23 and the handle 23 can be reliably rotated. In addition, when the handle 23 is rotated beyond an angle at which the torsion spring 33 is in a no-load state, an excessive load is not applied to the torsion spring 33 and the torsion spring 33 is sufficiently prevented from being deformed. Therefore, the torsion spring 33 can be sufficiently prevented from deteriorating due to an excessive load, and the handle 23 can be reliably rotated by the urging force of the torsion spring 33.

  Moreover, in this Embodiment, it is comprised so that the dust collector 2 may be attached to the cleaner main body 1 in the state inclined about 45 degree | times. Further, in the present embodiment, the operation unit 38 is disposed in the upper part in front of the dust collector 2, that is, the front surface of the upper lid 22, and the handle 23 is rotated in the direction from the housed state to the inverted state. At this time, the handle 23 is configured to rotate toward the rear of the dust collector 2. Therefore, the vacuum cleaner body 1 can be reduced in size, and the user can easily operate the operation unit 38. When the user operates the operation unit 38 and rotates the handle 23, the handle 23 is The user-friendliness of the vacuum cleaner 100 can be improved without hitting the user's hand.

  Furthermore, in the present embodiment, in order to rotate the handle 23 from the retracted state to the inverted state, the user moves the operation unit 38 into the upper lid 22 against the biasing force of the coil spring 39. When moved, the holding unit 37 is configured to move into the upper lid body 22 in conjunction with the operation of the operation unit 38. Moreover, in this Embodiment, in order to attach the dust collector 2 to the cleaner body 1, a user attaches the dust collector 2 to the dust collector housing part 11 of the cleaner body 1, and the handle 23 is inverted. When the handle 23 is rotated downward from the storage state and the handle 23 is pushed down, the holding unit 37 and the operation unit 38 are pushed into the upper lid 22 in conjunction with the rotation of the handle 23, and the handle 23 Is moved from the inside of the upper lid body 22 to the outside of the upper lid body 22 by the biasing force of the coil spring 39. With this configuration, the holding unit 37 can be moved to the inside of the upper lid body 22 in conjunction with the operation of the operation unit 38 and the rotation of the handle 23. Therefore, when the handle 23 is rotated, The friction with the holding part 37 can sufficiently prevent the holding part 37 from being worn. Therefore, the third recess 36 and the holding portion 37 can be reliably engaged against the urging force of the torsion spring 33, and the handle 23 can be reliably held in the stored state.

  In the vacuum cleaner of the present invention, when removing the dust collector from the vacuum cleaner main body, the user operates the operation portion and releases the engagement between the handle and the holding portion, and by the biasing force of the biasing means. The handle can be easily rotated, the engagement between the handle and the vacuum cleaner body can be released, and the dust collector can be easily detached from the vacuum cleaner body, so that a household vacuum cleaner and an industrial vacuum cleaner can be used. The present invention can be suitably applied to the fields and uses.
