  • FIG. 18 is a cross-sectional view illustrating a configuration of further another suction tool 72 for an electric vacuum cleaner, according to the second embodiment of the invention.
  • suction tool 72 for an electric vacuum cleaner is in common with those of the aforementioned suction tools 2 and 92 for electric vacuum cleaners except in that first seal member 59 is disposed, between first suction tool 10 and second suction tool 20, which is configured with a soft material having high wear resistance.
  • First seal member 59 may be disposed at the perimeter of first suction port 10a of first suction tool 10, or may be disposed at a portion, in contact with first suction port 10a, of second suction tool 20. With this configuration, it is possible to further efficiently prevent an air leakage from between first suction tool 10 and second suction tool 20, with first suction tool 10 being attached to second suction tool 20. This allows improved suction force of electric vacuum cleaner 100.
  • first seal member 59 in first suction tool 10, it is possible to prevent the surface to be cleaned from being scratched due to the contact between the surface and the end portion of first suction port 10a in the to-be-cleaned surface side, when the user uses only first suction tool 10 to clean the dust on the surface to be cleaned.
  • second seal member 60 may be disposed, between second suction tool 20 and third suction tool 30, which is configured with a soft material having high wear resistance. Second seal member 60 may be disposed at the circumference of second suction port 20a disposed in second suction tool 20, or may be disposed at a portion, in contact with second suction port 20a, of third suction tool 30. With this configuration, it is possible to further efficiently prevent an air leakage from between second suction tool 20 and third suction tool 30, with second suction tool 20 being attached to third suction tool 30. This allows improved suction force of electric vacuum cleaner 100.
  • second seal member 60 is disposed in second suction tool 20, when the user cleans the dust on the surface to be cleaned through the use of second suction tool 20, it is possible to prevent the surface to be cleaned from being scratched due to the contact between the surface and the end portion of second suction port 20a in the to-be-cleaned surface side.
  • suction tools 2, 72, 82, and 92 for electric vacuum cleaners for using each of the tools with first suction tool 10 being removed from second suction tool 20, only the operation of first operation part 42 allows the disengagement of first suction tool 10 from second suction tool 20. Moreover, for using each of the tools with second suction tool 20 being removed from third suction tool 30, only the operation of second operation part 48 allows the disengagement of second suction tool 20 from third suction tool 30. Therefore, it is possible to easily perform the switchover among first suction tool 10, second suction tool 20, and third suction tool 30, resulting in improved ease of use for the user.
  • first operation part 42 and second operation part 48 are disposed in third suction tool 30; however, the present invention is not limited to the cases.
  • at least one of first operation part 42 and second operation part 48 may be disposed in third suction tool 30.
  • the user is able to operate, by a simple action, the at least one of first operation part 42 and second operation part 48, thereby allowing the ease-of-use suction tool for an electric vacuum cleaner.
  • first operation part 42 and second operation part 48 are disposed in the rear portion of third suction tool 30; however, the present invention is not limited to the cases.
  • at least one of first operation part 42 and second operation part 48 may be disposed in the rear portion of third suction tool 30.
  • the user is able to operate, by a simple action, the at least one of first operation part 42 and second operation part 48, thereby allowing the ease-of-use suction tool for an electric vacuum cleaner.
  • first claw 25A serving as the first engaging part is disposed in the second suction tool 20 side and second recess 18A serving as the first to-be-engaged part is disposed in the first suction tool 10 side; however, the present invention is not limited to the cases.
  • first claw 25A and 25B may be disposed which serve as the first engaging part that detachably engages first suction tool 10 with second suction tool 20.
  • second recess 18A and second recess 18B may be disposed, at the positions corresponding to the first engaging part, which serve as the first to-be-engaged part that engages with the first engaging part.
  • first seal member 59 and second seal member 60 are formed of the soft material having high wear resistance; however, the present invention is not limited to the case.
  • at least one of first seal member 59 and second seal member 60 may be formed of the soft material having high wear resistance.
  • the configuration has been exemplified where soft members 58 are disposed on both end portions of first operation part 42 and second operation part 48; however, the present invention is not limited to the exemplified configuration.
  • the configuration may be such that the soft material is disposed at the end portion of at least one of first operation part 42 and second operation part 48.
  • the suction tools for electric vacuum cleaners and the electric vacuum cleaners equipped with the tools according to the present invention can provide the exceptional advantage that the switchover among first suction tool, second suction tool, and third suction tool can be easily performed.
  • the invention is useful for home-use electric vacuum cleaners, industrial electric vacuum cleaners, and the like which are equipped with suction tools for electric vacuum cleaners.
