Embodiment 1 FIG.
FIG. 1 is a diagram showing the configuration of the electric vacuum cleaner according to Embodiment 1 of the present invention. As shown in this figure, the vacuum cleaner of the present embodiment includes a vacuum cleaner main body 1, a negative rolling long portion 5 having one end detachably connected to the vacuum cleaner main body 1, and a suction port formed at the other end. It is composed of The vacuum cleaner body 1 includes a fan motor 2 that generates a suction force and a dust separation and accumulation unit 3 inside, and a handle 4 outside. The negative rolling long portion 5 is a tube configured so that the negative pressure generated by the fan motor 2 acts. The dust sucked from the negative rolling long part 5 by negative pressure flows into the dust separation and accumulation part 3 together with air. The dust separation / accumulation unit 3 separates and accumulates the inflowing dust from the air. Moreover, the vacuum cleaner of this Embodiment is provided with the bristle brush 7 as an accessory. The bristle brush 7 is for collecting dust in a narrow place and the like, and when the user performs the cleaning work by directly holding it in his hand, or when the cleaning work is performed by connecting to another device (not shown). Is used.

  The vacuum cleaner of the present embodiment includes a dust removing mechanism 6 in the vicinity of the suction port in the negative rolling long portion 5 as a characteristic configuration. FIG. 2 is a view for explaining the configuration and operation of the dust removing mechanism 6. As shown in FIG. 2, the dust removing mechanism 6 includes a plurality of protrusions (ribs) 61 that protrude from the inner wall of the negative rolling long portion 5 toward the inner space. In addition, the plurality of protrusions 61 are formed so as to project in an inclined manner toward the direction from the suction port toward the cleaner body 1 (that is, leeward of the negative rolling long portion 5), and are arranged in a staggered manner.

  In the electric vacuum cleaner of the present embodiment, the dust trapped by the bristle brush 7 is separated by the dust removing mechanism 6 and is sucked into the cleaner main body 1. More specifically, as shown in (A) of FIG. 2, first, the bristle brush 7 to which dust is attached by the cleaning operation is inserted into the negative rolling long portion 5 from the suction port side. As shown in FIG. 2B, when the bristle brush 7 reaches the dust removing mechanism 6 inside the negative rolling long portion 5, the dust attached to the dust removing mechanism 6 by sliding of the bristle brush 7 is removed. Is entangled with the plurality of protrusions 61 constituting the. Thereafter, when the bristle brush 7 is pulled out from the negative rolling long portion 5 as shown in FIG. 2C, the dust attached to the bristle brush 7 is effectively entangled by the protrusions 61. The dust entangled with the protrusion 61 is sucked into the dust separation and accumulation unit 3 inside the cleaner body 1 by driving the fan motor 2 of the vacuum cleaner.

  As described above, according to the electric vacuum cleaner of the present embodiment, the use of the bristle brush 7 enables a cleaning operation that does not generate noise, and removes dust adhering to the bristle brush 7 with a simple and small configuration. It becomes possible. Moreover, since the bristle brush 7 and the vacuum cleaner are comprised separately, the cleaning operation | work by the bristle brush 7 and the cleaning operation | work as a vacuum cleaner using the negative pressure by the fan motor 2 can be performed simultaneously. Furthermore, according to the vacuum cleaner of the present embodiment, the bristle brush 7 is not disposed in the dust suction air passage during the cleaning work as the vacuum cleaner, so the pressure loss is large. There is no fear that the cleaning efficiency by the electric vacuum cleaner will be reduced. Moreover, according to the shape and arrangement | positioning of the processus | protrusion 61 mentioned above, it can suppress effectively that the air loss in the negative rolling long part 5 is block | closed, and a pressure loss becomes large. Thus, according to the vacuum cleaner of the present embodiment, it is possible to provide an easy-to-use vacuum cleaner that achieves both the cleaning work by the bristle brush 7 and the cleaning work using the negative pressure by the fan motor 2. Can do.

  By the way, in the vacuum cleaner of embodiment mentioned above, although it decided to comprise the negative rolling long part 5 by the some protrusion 61 which inclined, the structure of the negative rolling long part 5 is not restricted to this. In other words, if the structure allows the dust adhering to the bristle brush to be entangled, the protrusion 61 takes into account the hardness of the bristle brush 7, the structural strength of the dust removing mechanism 6, the output of the fan motor 2, and the like. What is necessary is just to set suitably the shape, arrangement | positioning, quantity, material, etc. of this.

  Moreover, in the vacuum cleaner of embodiment mentioned above, it is good also as providing the following structures so that the operation | movement which inserts the bristle brush 7 into the negative rolling long part 5 can be performed more easily. For example, the vacuum cleaner body 1 may be provided with a structure in which the dust removing mechanism 6 is fixed in a state of facing substantially upward. Moreover, it is good also as making the structure which bend | folds the negative rolling long part 5 facilitate the dust removal operation | work from the bristle brush 7. FIG.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described. The electric vacuum cleaner according to the second embodiment is characterized in that it includes a moving mechanism 62 for changing the relative position of the bristle brush 7 with respect to the dust removing mechanism 6. FIG. 3 is a diagram for explaining the configuration of the dust removing mechanism of the electric vacuum cleaner according to the second embodiment. As shown in this figure, the moving mechanism 62 is connected to the bristle brush 7, the operation of pulling the bristle brush 7 to the dust removing mechanism 6 inside the negative rolling length portion 5, and the dust removing mechanism 6 to the negative rolling length. It is configured to be able to project outside the portion 5.

  As shown in FIG. 3, the moving mechanism 62 pulls the bristle brush 7 to which dust has adhered by the cleaning operation to the dust removing mechanism 6 inside the negative rolling long portion 5. Similar to the electric vacuum cleaner of the first embodiment, the dust removing mechanism 6 of the present embodiment has a plurality of protrusions 61 formed thereon. For this reason, when the bristle brush 7 reaches the dust removing mechanism 6 inside the negative rolling long portion 5, the dust adhering to the sliding of the bristle brush 7 is entangled with the plurality of protrusions 61 constituting the dust removing mechanism 6. Thereafter, when the moving mechanism 62 causes the bristle brush 7 to protrude from the negative rolling long portion 5 to the outside, the dust attached to the bristle brush 7 is effectively entangled by the protrusions 61. The dust entangled with the protrusion 61 is sucked into the dust separation and accumulation unit 3 inside the cleaner body 1 by driving the fan motor 2 of the vacuum cleaner.

  FIG. 4 is a diagram illustrating a specific configuration and operation of the moving mechanism. The moving mechanism 62 can be configured as shown in FIG. 4, for example. A moving mechanism 62 shown in FIG. 4A includes an elastic member 63 made of elastic polypropylene resin or the like, and the bristle brush 7 is connected to the tip side thereof. The rear end side of the elastic member 63 is connected to a winding shaft 66 disposed on the cleaner body 1 side with respect to the dust removing mechanism 6 of the negative rolling long portion 5. A gear 65 is provided coaxially with the take-up shaft 66, and the gear of the motor 64 meshes with the gear 65.

  In such a moving mechanism 62, as shown in FIG. 4B, first, the motor 64 is rotated forward. Thereby, the elastic member 63 is wound on the winding shaft 66, and the bristle brush 7 is pulled to the dust removing mechanism 6 inside the negative rolling long portion 5. Then, after the retraction operation, the rotation direction of the motor 64 is repeatedly switched so that the front end and the rear end of the bristle brush 7 are repeatedly slid within a range in which the bristle brush 7 reliably contacts the protrusion 61. Thereby, the dust adhering to the bristle brush 7 effectively adheres to the protrusion 61. Finally, when the motor 64 is driven in the reverse rotation, the motor 64 protrudes outward from the wound state due to the rigidity of the elastic member 63. According to such an operation of the moving mechanism 62, dust attached to the bristle brush 7 can be effectively removed.

  As described above, according to the electric vacuum cleaner of the second embodiment, the user performs the operation of attaching and detaching the bristle brush 7 between the cleaning of the narrow part using the bristle brush 7 and the cleaning by suction with the fan motor 2 or Since it can carry out without performing the operation | movement which changes to the bristle brush 7 of another body, usability improves.

  The configuration of the moving mechanism 62 is not limited to the above configuration as long as the bristle brush 7 can be pulled into the negative rolling long portion 5, regenerated by the dust removing mechanism 6, and pulled out from the negative rolling long portion 5. FIG. 5 is a diagram showing another configuration example of the moving mechanism. The moving mechanism 62 shown in FIG. 5 includes a support shaft 71 having rigidity, and the bristle brush 7 is connected to the tip of the support shaft 71. The support shaft 71 is supported by the support portion 72 so as to be movable along the extending direction of the pipe line of the negative rolling long portion 5. A gear 73 is formed on the rear end side of the support shaft 71 and meshes with the motor 75 via the gear 74. According to such a configuration, the bristle brush 7 can be pulled in and pulled out by the motor 75 rotating forward and backward.

  Further, the moving mechanism 62 shown in FIG. 5 is configured such that the direction of the rotating shaft of the motor 75 and the moving direction of the support shaft 71 are perpendicular to each other. You may comprise so that the moving direction of the support shaft 71 may become parallel. FIG. 6 is a diagram illustrating a configuration example of a moving mechanism using a worm gear. In the moving mechanism 62 shown in FIG. 6, the same components as those shown in FIG. In the moving mechanism 62 shown in FIG. 6, the motor 75 is arranged so that the rotating shaft of the motor 75 is parallel to the moving direction of the support shaft 71, and the motor 75 and the support shaft 71 connect the worm gears 76 and 77. Are engaged. Even in such a configuration, the bristle brush 7 can be pulled in and pulled out by the motor 75 rotating forward and backward.

  Moreover, in the electric vacuum cleaner of Embodiment 2 mentioned above, you may change the output of the fan motor 2 at the time of the reproduction | regeneration operation which removes the dust of the bristle brush 7, and the floor surface cleaning operation by a normal negative pressure. Moreover, it is good also as a form which performs the main cleaning operation | work with the bristle brush 7, and does not perform the cleaning using the suction from the front-end | tip opening part of the negative rolling long part 5. FIG. Thereby, in the reproduction | regeneration operation | movement of the bristle brush 7, since the output of the fan motor 2 can be reduced, the cleaning by low noise is attained. In general, the output of the fan motor 2 necessary for the floor cleaning operation by the normal negative pressure is large, and the noise accompanying this is large. For this reason, this function is particularly effective when cleaning at night or when the housemate is sleeping.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described. In the above-described electric vacuum cleaner of the second embodiment, the bristle brush 7 is slid in the axial direction of the negative rolling long portion 5 after the bristle brush 7 is pulled to the dust removing mechanism 6. The electric vacuum cleaner of the third embodiment is characterized in that it includes a rotation mechanism that rotates the bristle brush 7 in the axial direction.

  FIG. 7 is a diagram for explaining the configuration of the rotation mechanism of the electric vacuum cleaner according to the third embodiment. The rotation mechanism 80 shown in FIG. 7 is provided with a gear 81 at the rear end of the support shaft 71 to which the bristle brush 7 is connected. The motor 75 is arranged so that the rotation shaft thereof is parallel to the support shaft 71, and is engaged with the gear 81 via the gear 82. The support shaft 71 is provided with a spiral groove 83, and the support portion 72 is formed with a convex portion that meshes with the groove 83.

  According to such a configuration, the support shaft 71 is rotated by driving the motor 75, and the support shaft 71 is moved in the axial direction by the guide of the groove 83. Accordingly, since the bristle brush 7 can be rotated after being pulled up to the dust removing mechanism 6, the effect of effectively removing dust adhering to the bristle brush 7 can be obtained as in the above sliding operation. .

  In addition, in the vacuum cleaner of this Embodiment 3, the protrusion 61 of the dust removal mechanism 6 may be comprised as follows. FIG. 8 is a diagram showing the configuration of the dust removing mechanism of the third embodiment. In the dust removing mechanism 6 shown in this figure, the protrusion 61 is inclined in the rotation direction of the bristle brush 7. According to such a configuration, it is possible to avoid a situation where the required torque of the rotation mechanism 80 becomes excessive.

  In the electric vacuum cleaner of the third embodiment described above, the bristle brush 7 is moved and rotated by the rotation mechanism 80. However, the configuration of the rotation mechanism 80 is not limited to this, and the bristle brush may be rotated using another known technique. Further, in the rotation mechanism 80 described above, the groove 83 can also be moved in the axial direction. However, the rotation mechanism 80 may be configured so that only the rotation without the groove 83 is possible. In such a case, for example, the movement and rotation of the bristle brush 7 in the axial direction can be realized by using a mechanism combined with the movement mechanism 62 described above.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described. 9A and 9B are diagrams showing the configuration of the dust removal mechanism of the fourth embodiment.

The dust removing mechanism 6 includes a plurality of protrusions 61, a moving mechanism 91, a bristle brush guide 92, and an opening / closing mechanism 93. The moving mechanism 91 has the same configuration as the moving mechanism 62 of the second embodiment described above, and is for changing the relative position of the bristle brush 7 with respect to the dust removing mechanism 6. However, the moving mechanism 91 of the fourth embodiment is connected to an elastic member 63 extending along the outside of the negative rolling long pipe 51, and the bristle brush 7 is passed through the inside or the upper part of the negative rolling long head 52. It is configured to be able to protrude outward. The bristle brush guide 92 is a cover attached to a part on the outer wall side of the negative rolling long pipe 51 so as to cover the elastic member 63 and the moving mechanism 62 along the negative rolling long pipe 51. The protrusion 61 of the dust removing mechanism 6 of the present embodiment is provided inside the bristle brush guide 92. The opening / closing mechanism 93 is for opening and closing an opening communicating from the inside of the bristle brush guide 92 to the inside of the negative rolling long pipe 51, and for example, a sliding shutter can be used. When the opening is opened by the opening / closing mechanism 93, negative pressure of the cleaner body 1 is also generated inside the bristle brush guide 92. For this reason, the opening / closing mechanism 93 closes the opening so that the negative pressure in the negative rolling long head 52 does not decrease when the cleaning operation using the negative pressure by the fan motor 2 is performed.

  According to such a configuration, dust adheres to the bristle brush 7 protruding to the outside of the negative rolling long head 52 by the user's cleaning work. Here, when the moving mechanism 91 is driven, the bristle brush 7 is moved from the outside of the negative rolling long head 52 to the inside of the bristle brush guide 92. Here, the sliding operation described above is performed, and the inside of the bristle brush guide 92 and the inside of the negative rolling long pipe 51 are communicated by the opening / closing mechanism 93. At this time, the dust attached to the bristle brush 7 can be sucked into the negative rolling long pipe 51 by driving the fan motor 2.

  As described above, according to the configuration of the fourth embodiment, the negative rolling long head 52 is usually used for cleaning, and the negative rolling long head 52 is difficult to enter and a rubbing cleaning with the bristle brush 7. In a desirable situation, the bristle brush 7 extends to the front of the negative rolling long head 52 so that the cleaning operation can be performed conveniently. Further, it is possible to avoid troublesome work such as holding the bristle brush 7 in hand and exchanging attachments. Further, according to the configuration of the fourth embodiment, the bristle brush 7 can be housed in the bristle brush guide 92 when performing the cleaning operation from the normal negative rolling long head 52. improves.

  Further, according to the vacuum cleaner of the fourth embodiment, since the dust removing mechanism 6 is provided outside the negative rolling long pipe 51, the air passage in the negative rolling long pipe 51 is blocked and the pressure loss increases. Can be effectively suppressed. Thus, according to the vacuum cleaner of the present embodiment, it is possible to provide an easy-to-use vacuum cleaner that achieves both the cleaning work by the bristle brush 7 and the cleaning work using the negative pressure by the fan motor 2. Can do.

  By the way, as long as the structure of the moving mechanism 91 is a mechanism capable of pulling the bristle brush 7 into the bristle brush guide 92, regenerating it with the dust removing mechanism 6, and projecting it from the negative rolling length head 52 to the outside, the above structure is adopted.
