Japanese Patent No. 2627275 JP-A-4-364822

  In the prior art, when the vacuum cleaner body is used as a stick-type vacuum cleaner while being stored in the support, for example, when cleaning a floor on which a desk or table is placed, If the nozzle head is inserted into the nozzle and the nozzle head is moved along the floor for cleaning, the front part of the vacuum cleaner collides with a desk or table, etc. There is a possibility that the positional relationship of the support is shifted and airflow leakage occurs, or in some cases, the main body of the vacuum cleaner falls off the support. In addition, when a crack occurs in the dust collecting part or the like due to an impact at the time of a collision, there is a possibility that an airflow leak occurs due to the crack. In addition, the electric blower in the electric vacuum cleaner body may be damaged due to the impact at the time of collision. Furthermore, when using such a vacuum cleaner tilted backward, it may not only push forward along the floor surface, but may also pull backward along the floor surface. There is a risk of collision with an obstacle, and there is a risk that the hand will be released from the gripping part due to impact at the time of collision, etc., and the vacuum cleaner may be dropped on the floor surface.

A connection port 30 on the secondary side is provided upward. The first suction port 11 is connected to the connection port 30 in an airtight manner so as to be able to communicate with the connection port 30, and the first pipe-shaped portion 15 is provided around the rear side of the connection port 30. A first fitting receiving portion 31 that can be fitted to the left and right sides and the rear portion around the suction port 11 is U-shaped in a plan view and protrudes upward. On the other hand, in the upper part of the storage part 2, the part corresponding to the rear connection part 17 when the electric vacuum cleaner main body 1 is stored, in the embodiment, in the vicinity of the connection part between the rear connection part 17 and the grip part 18.

  The nozzle head 26 has a substantially T-shape in plan view and is provided with the horizontally long suction port 25 long open in the left-right direction at the lower front portion of a flat box-shaped head case 33. It communicates with the universal joint 27. A second intake path 34 is formed between the horizontally long suction port 25 and the connection port 30.

  In the vacuum cleaner having the above configuration, the vacuum cleaner body 1 is separated from the support 3 in order to clean the surface G to be cleaned such as on the top of a desk or table, and the vacuum cleaner body. When using 1, the user holds the electric vacuum cleaner main body 1 by grasping the grip 18 of the first grip 11 provided at the other end of the machine casing 4. Then, when the user operates the switch 20, the electric blower 8 is activated by the electric power from the rechargeable battery 9, and the fan 7 is rotated. A suction airflow is generated which is sucked through the pipe-shaped member 15, passes through the dust collection unit 5 and the electric blower 8, and is discharged out of the machine casing 4 through the exhaust path (not shown). Thus, the electric vacuum cleaner 8 is moved so that the first suction port 11 is brought close to the surface to be cleaned G and the first suction port 11 moves along the surface to be cleaned G in a state where the electric blower 8 is activated. By moving the main body 1, the suction airflow including dust is sucked from the first suction port 11, and the suction airflow including dust constitutes the first pipe-like portion constituting the first intake passage 12. 15 flows into the container 5 </ b> A of the dust collector 5 through the inlet 14.

  Then, the air flow including the dust that has entered the container 5A of the dust collecting unit 5 from the introduction port 14 is directed in the tangential direction of the inner surface of the container 5A by the air flow guiding unit 13A of the vortex generating means 13. Thus, the vortex flow swirls along the inner peripheral surface of the container 5A and descends spirally in the container 5A. At this time, at least coarse dust out of the dust contained in the vortex is separated from the vortex by being pressed against the inner peripheral surface of the container 5A of the dust collecting unit 5 by centrifugal force. The airflow from which coarse dust is separated by centrifugal force passes through the filter 22 provided in the center of the eddy current generating means 13. And when the said airflow passes the said filter 22, the fine dust which was not isolate | separated with the centrifugal force contained in the said airflow is filtered. Further, the airflow from which the dust has been removed by the filter 22 is discharged from the dust collecting unit 5 through the exhaust passage 23 and sucked into the electric blower 8. The dust separated from the airflow in this way is stored in the container 5A of the dust collecting unit 5. At this time, when the inlet 14 is used, the inlet 14 is disposed above the container 5A of the dust collecting portion 5 so that the dust accumulated in the container 5A is self-weighted from the inlet 14 to the container 5A. There is no return to the first inlet 11. The dust collected in the container 5A is removed from the machine casing 4 and the eddy current generating means 13 is removed from the container 5A to open the upper opening of the container 5A. It can be discarded by opening it.

  Thus, when the surface to be cleaned G such as the top of a desk or table is cleaned using the electric vacuum cleaner main body 1 alone, an obstacle (for example, display D) placed on the surface to be cleaned G is used. Etc.), the vacuum cleaner body 1 may collide. However, even if the vacuum cleaner main body 1 collides with an obstacle such as the display D, the position of the collision is the protection means 15A that covers the first pipe-shaped portion 15. As described above, since a slight gap is formed between the protection means 15A and the first pipe-like portion 15, the protection means 15A is configured to be deformable by an impact at the time of collision. Therefore, the impact is absorbed by the deformation of the protection means 15A, and the impact received by the first pipe-shaped portion 15 is reduced. Accordingly, not only can the first pipe-like portion 15 and the container 5A, that is, the dust collecting portion 5 be damaged, and the risk of airflow leakage can be reduced, but also the machine frame to which the dust collecting portion 5 is attached. It is possible to reduce a failure associated with an impact on the motor 6 and the fan 7 of the electric blower 8 provided in the case 4.

  On the other hand, in order to clean the surface to be cleaned F such as a floor surface under a desk or a table, when using the electric vacuum cleaner main body 1 on the support 3 as a stick type vacuum cleaner, Accommodates the vacuum cleaner main body 1 in the storage portion 2 of the support 3 so that the first suction port 11 of the vacuum cleaner main body 1 is connected to the connection port 30 of the support 3. The second holding portion 28 provided on the other end side of the support body 24 of the support 3 is held, and the nozzle head 26 provided on one end side of the support body 24 is placed on the surface F to be cleaned. Then, when the user operates the switch 20, the electric blower 8 is activated by the electric power from the rechargeable battery 9 and the fan 7 rotates, whereby the suction airflow including dust is secondly generated. The first pipe-shaped member is sucked from the horizontally long suction port 25, which is a suction port, and from the first suction port 11 through the nozzle head 26, the universal joint 27, and the connection port 30 (that is, the second intake passage 34). 15 (that is, the first intake passage 12) and flows into the container 5A of the dust collecting portion 5. The second half of the second intake passage 34 (from the universal joint 27 to the connection port 30) and the first intake passage 12 are linearly connected as shown in FIG. For this reason, there is less pressure loss than when the intake passage is bent, and not only the suction airflow flows smoothly to the container 5A, but also the dust collides with and adheres to the curved portion of the intake passage. Such problems are unlikely to occur. Since the separation of dust and the discharge of airflow are as described above, description thereof will be omitted.

  In this way, when the surface to be cleaned F such as a floor is cleaned using the electric vacuum cleaner as a stick type, an obstacle placed on the surface F to be cleaned (for example, a table top T of a desk or table). There is a risk that the vacuum cleaner may collide. However, even if the vacuum cleaner collides with an obstacle such as a table top T of a desk or table, the collision position is the hollow support body 24. As described above, since the support body 24 is configured to be hollow, the support body 24 is configured to be deformable by an impact at the time of collision. Therefore, the impact is absorbed by the deformation of the support body 24. Thus, the impact received by the main body 1 attached to the support 3 is alleviated. As a result, it is possible to reduce a failure associated with an impact on the motor 6 or the fan 7 of the electric blower 8 provided in the machine casing 4 of the electric vacuum cleaner main body 1 attached to the support 3. .

  Further, when cleaning with the vacuum cleaner body 1 attached to the support 3, the rear of the vacuum cleaner collides with an obstacle when the vacuum cleaner is pulled rearward along the surface F to be cleaned. There is a risk that the electric vacuum cleaner will fall when the hand is separated from the second grip portion 28 and the rear of the electric vacuum cleaner may collide with the floor F. However, in such a case, the protective means 15A covering the first pipe-shaped portion 15 attached rearward collides with the floor F, and as described above, the protective means 15A and the first pipe-shaped portion 15 15 is formed so that the protection means 15A can be deformed by an impact at the time of collision. Therefore, the impact is absorbed by the deformation of the protection means 15A, and the first The impact received by the pipe-like portion 15 is reduced. Accordingly, not only can the first pipe-like portion 15 and the container 5A, that is, the dust collecting portion 5 be damaged, and the risk of airflow leakage can be reduced, but also the machine frame to which the dust collecting portion 5 is attached. It is possible to reduce a failure associated with an impact on the motor 6 and the fan 7 of the electric blower 8 provided in the case 4.

  Note that when the electric vacuum cleaner main body 1 is attached to the support 3 and used as a stick-type vacuum cleaner, the impact when the support main body 24 collides with an obstacle such as a table or a table top T. Is larger than the impact when the protection means 15A collides with an obstacle such as the display D when the vacuum cleaner body 1 is used alone as a hand-held vacuum cleaner. This is because the difference between the total weight of the support 3 and the vacuum cleaner main body 1 and the weight of the vacuum cleaner main body 1 alone is that an obstacle placed on the surface to be cleaned F such as a floor is a desk or table. The weight tends to be larger than the obstacle placed on the surface to be cleaned G such as a top plate, and the speed of moving the stick type vacuum cleaner on the surface to be cleaned F such as the floor is This is because, for example, the speed tends to be higher than the speed of moving the hand-held vacuum cleaner on the surface to be cleaned G such as a table top. Accordingly, the support body 24 of the support 3 needs to be formed in a shape and size that allow for a large impact when used as a stick-type vacuum cleaner. The protection means 15A provided on the vacuum cleaner body 1 may be formed in a shape and size that allow for a relatively small impact when the vacuum cleaner body 1 is used alone. The increase in size can be suppressed, and the usability when the vacuum cleaner main body 1 is used alone can be prevented from being lowered.

  When the vacuum cleaner body 1 is attached to the support 3 and used as a stick-type vacuum cleaner, the support body 24 on the front side of the vacuum cleaner is a table or table top plate T or the like. The impact when colliding with an obstacle tends to be larger than the impact when the protective means 15A on the rear side of the vacuum cleaner collides with an obstacle. This is because, as shown in FIG. 2, when the vacuum cleaner is tilted backward, when the vacuum cleaner is pushed forward along the surface F to be cleaned, the support body 24 of the vacuum cleaner is A force that presses the vacuum cleaner against the surface F to be cleaned by an impact when it collides with an obstacle such as a table top T of a desk or table works, and the force at the time of collision between the table top T and the surface F to be cleaned When the vacuum cleaner is drawn back along the surface F to be cleaned, there is an obstacle between the user and the vacuum cleaner that may collide with the protection means 15A. Since it must be present, it is relatively low, so that the force that lifts the vacuum cleaner from the surface to be cleaned F by the impact when the protective means 15A of the vacuum cleaner collides with a low obstacle works. As a result, the force at the time of collision is released moderately. Succoth is because it is. Further, the frequency of collision of the support body 24 on the front side of the vacuum cleaner is higher than the frequency of collision of the protection means 15A on the rear side of the vacuum cleaner. This is because, as described above, when an obstacle collides with the protection means 15A, the obstacle must be present between the user and the vacuum cleaner. For this reason, in the vacuum cleaner in a state of being used as a stick type, the protection means 15A located on the rear side of the vacuum cleaner has a relatively small collision impact when the vacuum cleaner body 1 is used alone. Even if it is formed in the expected shape and size, the electric vacuum cleaner main body 1 can be sufficiently protected from an impact caused by a collision with an obstacle.

As described above, in the above-described embodiment, the first suction port 11 is formed at one end, and the dust collecting unit 5 and the electric blower connected to the first suction port 11 via the first intake passage 12. 8 and the other end of the vacuum cleaner main body 1 provided with a first gripping portion 10, and a support 3 having a storage portion 2 for detachably storing the vacuum cleaner main body 1. 3 has a nozzle head 26 at one end thereof and a second gripping portion 28 at the other end thereof. The nozzle head 26 is provided with a horizontally long suction port 25 as a second suction port, and the horizontally long suction port 25. A second intake passage 34 that can be connected to the vacuum cleaner main body 1 is configured to communicate with the dust collecting unit 5 and the electric blower 8 when the electric vacuum cleaner main body 1 is stored. And the storage part 2 appears on the rear side of the support 3 In addition, the vacuum cleaner main body 1 can be stored in the storage portion 2 so that the protection means 15A faces backward, so that the vacuum cleaner main body 1 can be used alone for a desk or table. When cleaning the surface to be cleaned G such as a top plate, even if it collides with an obstacle such as a display D in front of the surface to be cleaned G, the protection means 15A protects the dust collecting part 5 from the impact. By doing so, it is possible to prevent damage to the dust collector 5 and, consequently, the electric blower 8 in the machine casing 4 to which the dust collector 5 is attached. Further, when the surface to be cleaned F such as a floor is cleaned using the vacuum cleaner body 1 attached to the support 3, the support 3 can be used to clean an obstacle such as a top plate T in front. machine it is possible to protect the vacuum cleaner main body 1 by the support 3 also collide, collide with obstacle rear of the vacuum cleaner when the vacuum cleaner was drawn along the surface to be cleaned F Even if the hand is released from the second gripping part 28 during cleaning and the rear part of the vacuum cleaner collides with the surface F to be cleaned, the protective means 15A located at the rear part of the vacuum cleaner From the impact of these collisions, the dust collector 5 and thus the electric blower 8 in the machine casing 4 to which the dust collector 5 is attached can be protected. Furthermore, since the protection means 15A may be formed in a shape and size that allow for a relatively small impact when using the vacuum cleaner body 1 alone, the protection means 15A can be minimized. As a result, the vacuum cleaner main body 1, and thus the entire vacuum cleaner can be kept compact without increasing the size thereof, whereby the operability of the vacuum cleaner can be maintained. .

  Further, the protection means 15A is provided in the length direction in a portion corresponding to the front portion when the vacuum cleaner main body 1 is used alone, and the length direction of the protection means 15A, that is, the protection means 15A. When the storage unit 2 is provided so that the central axis A is substantially along the length direction of the support 3, the vacuum cleaner main body 1 is used alone or together with the support 3. In this case, the protection means 15A is oriented vertically, and as a result, the effective length of impact absorption by the protection means 15A can be increased as much as possible.

  Further, by providing the protective means 15A around the substantially straight first pipe-shaped portion 15 that forms the first intake passage 12, the electric vacuum cleaner main body 1 is prevented from being enlarged and downsized. be able to.

  Further, when the electric vacuum cleaner main body 1 is stored, the second intake passage 34 communicates with the dust collecting unit 5 and the electric blower 8 through the first intake port 11, so that the first intake port 11 is changed. By housing the electric vacuum cleaner main body 1 in the housing portion 2 so as to be connected to the connection port 30, the second air intake passage 34 is connected to the dust collecting portion 5 and the electric air blower via the first air intake passage 12. It can be easily connected to the device 8.

  In addition, this invention is not limited to the above Example, A various deformation | transformation implementation is possible within the range of the summary of invention. For example, in the above embodiment, the protective means made of synthetic resin can be deformed by interposing a slight gap around the pipe-shaped part. The protective means may be formed by coating the periphery with a soft synthetic resin called an elastomer.

  As described above, the vacuum cleaner according to the present invention can be applied to various uses. The dust collecting unit may be a filter type instead of a cyclone separator.
