  Further, as shown in FIGS. 3 and 6, the lower case 32 is formed with a plurality of slit-shaped holes 32B.

  As shown in FIG. 3, the partition wall 33 is sandwiched between the peripheral portion 31 </ b> C of the bulging portion 31 and the peripheral portion 32 </ b> A of the lower case 32. And this partition wall 33 has 33 A of axial holes penetrated and formed in the center part, and the air passage hole 33B penetrated and formed in the peripheral part vicinity.

  The shaft hole 33A is inserted through a rotation shaft 43 (to be described later) of the turbine 40 so as to be rotatable, and is fitted with a bearing (not shown).

  The turbine chamber 34 communicates with the atmosphere through the air holes 31B, and communicates with the dust collection chamber 12 through the air passage holes 33B.

  That is, the air passage hole 33 </ b> B communicates with the inside of the lower case 32 fixed to the back surface side of the lid case 21 that covers the dust collection chamber 12. The inner side of the lower case 32 communicates with the dust collecting chamber 12 through a slit-like hole 32B. Therefore, the turbine chamber 34 communicates with the dust collection chamber 12 through the inside of the lower case 32 and the air passage hole 33B.

  As shown in FIGS. 3 and 5, the hitting member 35 is formed by providing a plurality of hitting ribs 35 </ b> B on a flat substrate 35 </ b> A. A bearing hole 35C is formed through the center of the substrate 35A.

  Further, here, as shown in FIG. 4, side walls S projecting on the opposite side of the hitting rib 35 </ b> B are erected on the peripheral portion of the substrate 35 </ b> A and the peripheral portion of the bearing hole 35 </ b> C.

  The hitting member 35 is disposed inside the lower case 32, and the hitting rib 35B protrudes downward from the hole 32B of the lower case 32 as shown in FIG.

  As shown in FIGS. 3 and 4, the turbine 40 includes a rotating disk part 41 having a large number of blades 41 </ b> A... And a shaft part 42 provided at the center of the rotating disk part 41. ing.

  The rotating disc portion 41 is a disc-like plate-like body disposed in the turbine chamber 34, and a large number of wings 41 </ b> A... Protrude from the peripheral portion on the lower surface 41 a side facing the partition wall 33. Has been.

  These wings 41 </ b> A are arranged radially toward the center of the rotating disc part 41 and are slightly curved so as to be easily subjected to wind.

  The shaft portion 42 is formed to protrude from the lower surface 41a of the rotating disk portion 41, and protrudes larger than the wing 41A as shown in FIG. Further, the outer diameter of the shaft portion 42 is larger than the inner diameter of the shaft hole 33A so as not to protrude from the shaft hole 33A.

  The shaft portion 42 of the turbine 40 is connected to a rotating shaft 43 serving as a rotational power transmission means and an eccentric shaft 44 provided at the tip of the rotating shaft 43.

  The rotation shaft 43 is connected to the center of the shaft portion 42 of the turbine 40, is rotatably held by a bearing (not shown) fitted in the shaft hole 33A, and passes through the shaft hole 33A.

  The eccentric shaft 44 has a flat plate portion 44A connected to the rotation shaft 43 and an eccentric shaft portion 44B formed to project from the peripheral edge portion of the flat plate portion 44A.

  The flat plate portion 44A is located in the vicinity of the bearing hole 35C of the hitting member 35, and the eccentric shaft portion 44B is inserted into the bearing hole 35C. Here, the outer diameter of the flat plate portion 44A is formed larger than the inner diameter of the bearing hole 35C, and the eccentric shaft portion 44B cannot be removed by the side wall S standing on the peripheral edge of the bearing hole 35C coming into contact with the flat plate portion 44A. It is like that.

  Then, the rotating disk portion 41 rotates to rotate the shaft portion 42, and the rotating shaft 43 and the eccentric shaft 44 rotate together with the rotation of the shaft portion 42. At this time, since the eccentric shaft portion 44B of the eccentric shaft 44 is inserted into the bearing hole 35C of the hitting member 35, the hitting member 35 also rotates in conjunction with it. Thereby, the rotational force of the turbine 40 can be transmitted to the tapping member 35.

  Since the hitting rib 35B of the hitting member 35 is inserted into the slit-like hole 32B, the rotational movement is restricted by the hole 32B and the hitting member 35 moves along the hole 32B.

  Next, operation | movement of the vacuum cleaner 10 comprised as mentioned above is demonstrated.

  When the electric blower 13 is stopped, the turbine chamber 34 of the tapping device 30 shown in FIG. 3 is at atmospheric pressure, and the turbine 40 is stopped.

  At this time, the hitting rib 35B of the hitting member 35 is in contact with the upper surface of the dust bag 19 (see FIG. 3).

  In this state, when the electric blower 13 is driven by the operation of the operation switch Sa of the hand operation tube 17, suction negative pressure acts on the dust collection chamber 12.

  This negative suction pressure acts on the suction chamber (not shown) of the suction port body 20 via the dust collecting hose 15, the hand control pipe 17 and the extension pipe 18, and the suction opening of the suction chamber on the bottom surface of the suction port body 20. Dust and air on the surface to be cleaned are sucked from (not shown). The sucked dust and air are sucked into the dust collecting chamber 12 of the cleaner body 11 through the extension pipe 18, the hand operating pipe 17 and the dust collecting hose 15.

  The dust sucked into the dust collecting chamber 12 is collected in a dust collecting bag 19 mounted in the dust collecting chamber 12, and the air is sucked into the electric blower 13 and then exhausted from an exhaust hole (not shown) of the cleaner body 11. To go.

  On the other hand, when a suction negative pressure acts on the dust collection chamber 12 by driving the electric blower 13, the suction negative pressure is passed through the hole 32 </ b> B of the lower case 32 and the air passage hole 33 </ b> B of the partition wall 33 in order. The turbine chamber 34 has a negative pressure.

  When the pressure in the turbine chamber 34 becomes negative, a pressure difference is generated between the turbine chamber 34, the air flows into the turbine chamber 34 from the air holes 31B formed in the main body 31A, and the lower case from the air passage holes 33B. This air flows into the dust collecting chamber 12 through the 32 holes 32B.

  At this time, the air flowing through the turbine chamber 34 hits the wing 41A, and the rotating disk portion 41 rotates.

  Then, the shaft portion 42 rotates integrally with the rotation of the rotating disk portion 41, and the rotation shaft 43 and the eccentric shaft 44, which are rotational power transmission means, rotate by the rotation of the shaft portion 42. To do.

  Here, since the eccentric shaft portion 44B of the eccentric shaft 44 is inserted into the bearing hole 35C of the hitting member 35, the eccentric shaft portion 44B contacts the side wall S of the bearing hole 35C by the rotation of the eccentric shaft 44. Thereby, the tapping member 35 moves to vibrate the dust bag 19.

  The hitting member 35 has a hitting rib 35B protruding from the hole 32B of the lower case 32, so that the movement trajectory is regulated by the hole 32B, and here, the hitting member 35 moves along the front-rear direction of the cleaner body 11. ing.

  While the electric blower 13 is being driven, negative pressure continues to act on the turbine chamber 34, so that air flows into the turbine chamber 34, the turbine 40 continues to rotate, and the dust collection bag 19 continues to vibrate. be able to.

  As a result, the dust collection bag 19 can be vibrated frequently, and a reduction in suction force due to clogging of the dust collection bag 19 can be prevented.

  Further, since the tapping member 35 is moved by the rotational force of the turbine 40 to vibrate the dust collection bag 19, the dust collection bag 19 can be vibrated with a strong force even if a driving source such as a motor is not provided.

  Furthermore, in this case, since the turbine 40 is rotated by the air flowing toward the dust collecting chamber 12, it is possible to make it difficult for dust to adhere to the turbine 40.

  Hereinafter, a vacuum cleaner according to Embodiment 2 of the present invention will be described. In addition, about the site | part equivalent to the vacuum cleaner 10 of above-mentioned Example 1, the same code | symbol is used and detailed description is abbreviate | omitted.

  In the electric vacuum cleaner according to the second embodiment, as shown in FIG. 7A, the gear portion 50 is formed so as to protrude along the entire circumference of the circumferential surface of the rotating shaft 43 connected to the turbine 40.

  Further, a support arm 51 is formed to project from the inner wall surface of the bulging portion 31 (not shown in FIG. 7).

  A support pin 51A that protrudes sideways is formed at the tip of the support arm 51, and one end of a coil spring (biasing member) 52 is fitted into the support pin 51A.

  On the other hand, a rack gear 53 is engaged with the gear portion 50, and the other end of the coil spring 52 is fitted to a support pin 53A formed on the back surface 53a side of the rack gear 53. That is, the rack gear 53 is held by the support arm 51 via the coil spring 52.

  The coil spring 52 is disposed along the back surface 53 a of the rack gear 53 and biases the rack gear 53 in a direction in which the rack gear 53 is separated from the support arm 51.

  And in this vacuum cleaner, when the rotation disc part 41 of the turbine 40 rotates in the direction shown by arrow X (refer FIG. 7A) with the drive of the electric blower 13, this rotation disc part The rotation shaft 43 rotates integrally with 41. At this time, the gear portion 50 protruding from the circumferential surface of the rotation shaft 43 also rotates in the direction indicated by the arrow X.

  Since the rack gear 53 is engaged with the gear portion 50, the rack gear 53 moves in the direction indicated by the arrow Y (see FIG. 7A) while contracting the coil spring 52 as the gear portion 50 rotates.

  That is, the coil spring 52 is deformed in the reduction direction against the urging force by the rotation of the turbine 40.

  Then, as shown in FIG. 7B, when the coil spring 52 is contracted to the maximum extent, the rack gear 53 cannot be moved any more and stops, whereby the rotation of the gear unit 50 is stopped and the turbine is stopped. 40 stops.

  At this time, since the suction negative pressure by the electric blower 13 (not shown in FIG. 7) is acting on the turbine chamber 34 (not shown in FIG. 7), the air continues to flow, and the turbine 40 moves in the direction of the arrow X. The rotation stops in a state where the rotating force is acting.

  When the turbine 40 rotates while the coil spring 52 is contracted, the tapping member 35 (not shown in FIG. 7) is moved by the turbine 40, and the dust bag 19 (not shown in FIG. 7) vibrates. To do.

  When the driving of the electric blower 13 is stopped, the suction negative pressure does not act on the turbine chamber 34, and the pressure in the turbine chamber 34 becomes atmospheric pressure.

  As a result, air does not flow into the turbine chamber 34 and the force acting on the turbine 40 is released.

  Therefore, the coil spring 52 is restored by its own urging force, and the rack gear 53 is moved in the direction opposite to the direction indicated by the arrow Y. As a result, the gear unit 50 rotates in the direction opposite to the direction indicated by the arrow X, thereby rotating the turbine 40.

  And when this turbine 40 rotates, the hitting member 35 moves and the dust collection bag 19 can be vibrated.

  At this time, since the drive of the electric blower 13 is stopped and the suction negative pressure is not acting, the dust attached to the dust bag 19 can be easily removed and the dust can be removed more effectively.

  In the second embodiment, the coil spring 52 is used as the biasing member. However, the coil spring 52 is not limited to this as long as it has a biasing force.

  Hereinafter, the vacuum cleaner of Example 3 of this invention is demonstrated. In addition, about the site | part equivalent to the vacuum cleaner 10 of above-mentioned Example 1 and the vacuum cleaner of Example 2, the same code | symbol is used and detailed description is abbreviate | omitted.

  In the electric vacuum cleaner of the third embodiment, as shown in FIG. 8, a cylindrical recess 60 is formed in the main body 31 </ b> A of the bulging portion 31, and a pair of air holes 61 are formed on the bottom surface 60 </ b> A of the recess 60. 61 and a pin insertion hole 62 are formed.

  As shown in FIG. 9, the pin insertion hole 62 is formed in the center of the bottom surface 60 </ b> A, and the pair of air holes 61, 61 are formed in a fan shape at positions facing each other across the pin insertion hole 62.

  Further, a groove 63 is provided along the depth direction on the peripheral surface of the indented portion 60 to fit a rotation preventing portion 72A of a closing valve 70 described later.

  And in the dent part 60, the closing valve 70 is arrange | positioned via the spring SP (refer FIG. 8). This spring SP is fitted in the recess 60 and urges the closing valve 70 upward. That is, the closing valve 70 is held at a distance from the bottom surface 60 </ b> A of the recess 60 by the spring SP.

  9 and 10, the spring SP is omitted for convenience of explanation.

  The shut-off valve 70 includes a short cylindrical valve portion 71 opened upward, a flange portion 72 provided at the opening peripheral edge of the valve portion 71, and a lock pin 73 protruding downward from the bottom surface 71A of the valve portion 71. Have.

  The valve portion 71 has a pair of vent holes 71B and 71B (see FIG. 9) formed in the bottom surface 71A, and is inserted and fitted to one end of the spring SP as shown in FIG. The vent holes 71B and 71B are formed in a fan shape at positions facing each other. The vent holes 71B and 71B are formed at positions that do not overlap with the air holes 61 and 61 when viewed from above.

  The flange portion 72 is in contact with one end of the spring SP to prevent the spring SP from coming off. Further, as shown in FIG. 9, the flange portion 72 is formed with a rotation preventing portion 72 </ b> A protruding sideways.

  The lock pin 73 passes through the spring SP, passes through the pin insertion hole 62, and further passes through the insertion hole 33 </ b> C formed in the partition wall 33. And the front-end | tip part of this lock pin 73 is contacting the gear main body 55A of the rack gear 55 mentioned later.

  On the other hand, the flat plate portion 44A ′ of the eccentric shaft 44 ′ has a gear shape as shown in FIG. The rack gear 55 meshes with the flat plate portion 44A ′.

  The rack gear 55 includes a flat gear body 55A, a meshing portion 55B having a large number of teeth formed on one side surface of the gear body 55A, and a support protrusion 55C formed on one end of the other side surface of the gear body 55A. And a lock hole 55D formed in the vicinity of the support protrusion 55C.

  The rack gear 55 is supported by the support arm 51 via a coil spring 52 as an urging member. That is, one end of the coil spring 52 is fitted to the support pin 51A of the support arm 51, and the other end of the coil spring 52 is fitted to the support pin 55c protruding from the support protrusion 55C.

  In this electric vacuum cleaner, when the suction negative pressure acts on the turbine chamber 34 by driving the electric blower 13, air flows from the atmosphere into the turbine chamber 34 and the rotating disc portion 41 of the turbine 40 rotates.

  Here, the air flowing into the turbine chamber 34 flows through the vent holes 71 </ b> B and 71 </ b> B and the atmospheric holes 61 and 61 of the blocking valve 70.

  Then, the rotating shaft 43 rotates integrally with the rotating disk portion 41, and the gear-shaped flat plate portion 44A 'rotates in the direction indicated by the arrow X (see FIG. 9). Further, as the flat plate portion 44A ′ rotates, the rack gear 55 moves in the direction indicated by the arrow Y (see FIG. 9) while contracting the coil spring 52.

  That is, the coil spring 52 is deformed in the reduction direction against the urging force by the rotation of the turbine 40.

  At this time, air from the atmosphere flows into the inside of the recessed portion 60 through the vent holes 71B and 71B. Due to this air, the valve portion 71 of the closing valve 70 is pulled downward, and a downward force is applied to the valve portion 71.

  However, the closing valve 70 cannot be moved downward because the distal end portion of the lock pin 73 is in contact with the gear body 55A, and is held in a state of being spaced from the bottom surface 60A of the recessed portion 60. Is done.

  Then, as shown in FIG. 10, when the coil spring 52 is fully contracted, the rack gear 55 cannot move any more and stops, thereby stopping the rotation of the flat plate portion 44A ′ and the turbine 40. Stop.

  At the same time, the lock hole 55 </ b> D formed in the rack gear 55 faces the lock pin 73. As a result, the lock pin 73 can be inserted into the lock hole 55D, so that the valve portion 71 moves downward against the biasing force of the spring SP, and the lock pin 73 is inserted and fitted into the lock hole 55D.

  Here, since the rotation prevention part 72A provided in the flange part 72 of the closing valve 70 is fitted in the groove 63 of the indentation part 60, the valve part 71 can move downward without rotating.

  When the valve portion 71 moves downward and contacts the bottom surface 60A of the dent portion 60, the atmospheric holes 61 and 61 formed in the bottom surface 60A are closed by the valve portion 71, and the flow of air from the atmosphere stops. .

  Since the suction negative pressure acts on the turbine chamber 34 via the air passage hole 33B, a downward pulling force continues to act on the valve portion 71 even when the air flow from the atmosphere stops. . Further, since the valve portion 71 has a short cylindrical shape, the valve portion 71 can be fitted into the spring SP to be in close contact with the bottom surface 60A.

  On the other hand, when the flow of air from the atmosphere stops, the rotational force acting on the turbine 40 is released. However, at this time, since the lock pin 73 is inserted and fitted into the lock hole 55D, the movement of the rack gear 55 is prevented, and the turbine 40 stops in the state shown in FIG. That is, the lock pin 73 and the lock hole 55 </ b> D serve as a lock unit that locks the restoration of the coil spring 52, prevents the rack gear 55 from moving, and stops the rotation of the turbine 40.

  When the turbine 40 rotates while the coil spring 52 is contracted, the tapping member 35 is moved by the turbine 40 and the dust bag 19 vibrates.

  When the driving of the electric blower 13 is stopped, the suction negative pressure does not act on the turbine chamber 34, and the pressure in the turbine chamber 34 becomes atmospheric pressure.

  Thereby, the force pulling the valve portion 71 downward is released, and the valve portion 71 is pushed upward by the urging force of the spring SP.

  As the valve portion 71 moves upward in this manner, the lock pin 73 is disengaged from the lock hole 55D, and the lock means is released. Therefore, the coil spring 52 is restored by its own urging force, and the rack gear 55 is simply moved in the direction indicated by the arrow Y. As a result, the flat plate portion 44 </ b> A ′ rotates in the direction opposite to the direction indicated by the arrow X to rotate the turbine 40.

  And when this turbine 40 rotates, the hitting member 35 moves and the dust collection bag 19 can be vibrated.

  In this way, when the electric blower 13 is driven, the air holes 61 and 61 are closed by the valve portion 71, so that air leakage can be prevented and the suction work rate can be improved.

  At this time, the lock pin 73 is fitted into the lock hole 55D to prevent the rack gear 55 from moving and prevent the coil spring 52, which is an urging member, from being restored. Therefore, even if the air flow from the atmosphere stops, the coil spring 52 The electric blower 13 is stopped and the dust can be removed in a state where the suction negative pressure is not acting.

  In the third embodiment, the coil spring 52 is used as the biasing member. However, the coil spring 52 is not limited to this as long as it has a biasing force, and may be a spring or a leaf spring, for example.

  Further, the blocking valve 70 is prevented from rotating by a locking portion 72A provided in the flange portion 72 being fitted in the groove 63. For example, the locking valve 73 is prevented from rotating between the lock pin 73 and the pin insertion hole 62. Concavities and convexities that prevent the above may be provided.

  Although one embodiment according to the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the above-described embodiment. Design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.

  For example, in the above-described embodiment, the tapping device 30 is disposed above the dust collection chamber 12 and uses the pressure difference between the pressure in the dust collection chamber 12 and the atmospheric pressure, but is not limited thereto. That is, the turbine is not limited to rotating the turbine using the suction air, but may be rotated using the exhaust air.

  In this case, as shown in FIG. 11, the turbine 40 is disposed above the blower chamber 13A in which the electric blower 13 is disposed. An air hole 80 that communicates between the turbine chamber 34 in which the turbine 40 is disposed and the atmosphere is formed in the cleaner body 11, and an air passage hole 82 </ b> A that communicates the blower chamber 13 </ b> A and the turbine chamber 34 is formed in the partition wall 82. To do.

  Further, one end of a shaft 83 is connected to the tip of the shaft portion 42 of the turbine 40 via an eccentric shaft H, and a tapping member 35 is attached to the other end of the shaft 83.

  Thereby, when the electric blower 13 is driven, the pressure in the blower chamber 13A is increased, a pressure difference from the atmospheric pressure is generated, and air flows from the blower chamber 13A to the turbine chamber 34 through the air passage hole 82A. Air flows out to the atmosphere through the air holes 80.

  The turbine 40 rotates by the air flowing toward the atmosphere, and the tapping member 35 can be moved to vibrate the dust bag 19.

  In this case, since the turbine 40 does not need to be disposed above the dust collection chamber 12, the dust collection chamber 12 can be enlarged.

  Furthermore, in the above-described embodiment, the dust collection bag 19 is used as the dust collection filter body. However, the present invention is not limited to this, and a so-called secondary filter that collects fine dust contained in the air after separating the dust by inertia separation or the like. It may be.

  Moreover, although the above-mentioned Example demonstrated the canister type | formula vacuum cleaner, it applies to the vacuum cleaner which attaches the filter for dust separation to an upright type vacuum cleaner, a hand control tube, etc. You can also.
