  In the vertical vacuum cleaner shown in FIG. 16, the load on the main body is concentrated on the hand side, so that the operator may feel the weight. Moreover, in the vertical vacuum cleaner shown in FIG. 17, since the load of a main-body part concentrates on the suction inlet 6 side, the suction inlet 6 may not be moved easily.

  Furthermore, in the vertical vacuum cleaner disclosed in Patent Document 1, the position of the main body can be changed by the sliding operation of the main body. However, the structure of the apparatus becomes complicated because a support column and a sliding mechanism for sliding the main body and a lock mechanism for fixing the position of the main body are required.

  Moreover, in each said vertical vacuum cleaner, since the dust collection part is provided in a part of the same housing | casing as the main-body part with a built-in electric blower, it is necessary to replace the dust collection bag in the dust collection part. However, when fine dust leaking from the dust collecting part adheres to the vicinity of the dust collecting part, there is a problem that the dust collecting part cannot be completely cleaned by washing or other means.

  Accordingly, the present invention has been made to solve the above-described problems, and employs a structure that separates the main body part and the dust collecting part with a built-in electric blower, and can improve operability during cleaning work. It is to provide a vertical vacuum cleaner.

  In the vertical vacuum cleaner based on the present invention, the vertical vacuum cleaner has a suction port for sucking dust on the floor surface and other surfaces to be cleaned on the front end side and a handle on the rear end side.

  Further, in the vertical vacuum cleaner, the attachment / detachment structure between the dust collection part and the main body part employs a fitting structure that allows the dust collection part to be attached / detached only on the suction port side of the main body part. The

  In the vertical vacuum cleaner, the fittings that can be attached to and detached from each other at least between the suction port and the dust collection unit and between the main body unit and the handle unit. A conformable structure is adopted.

  Further, in the vertical vacuum cleaner, the dust collecting part has a vertically long swirl type dust separation system (cyclone system) structure.

  According to the vertical vacuum cleaner based on this invention, the dust collection part is provided with the structure provided with respect to a main-body part so that attachment or detachment is possible. As a result, even if fine dust leaking from the dust collecting part adheres to the dust collecting part, the dust collecting part is separated from the main body part by washing with water or other means, and only the dust collecting part is completely cleaned. Is possible. Moreover, since the main body part and the dust collecting part can be arranged apart from each other, the concentration of the load can be avoided and the load can be distributed, so that the operability of the vertical vacuum cleaner can be improved. .

  In addition, it is possible to prevent a fitting error by adopting a fitting structure that allows the dust collecting part to be attached and detached only on the suction port side of the main body part. Furthermore, between the suction port and the dust collecting part, and between the main body part and the handle part, when adopting a detachable fitting structure, various fitting patterns occur, It is possible to reliably prevent a fitting error in such a case. In addition, as a result of adopting various fitting patterns, the center position of the load can be appropriately changed according to the preference of the operator, the position on the handle side, the position on the suction port side, and the intermediate position between them. It becomes possible.

  In addition, by adopting a vertically-oriented swirling dust separation system (cyclone system) structure for the dust collection part, a part of the tubular member between the suction port and the main body part can be used as a dust collection part. Therefore, the apparatus configuration can be simplified.
