An airflow is generated that flows out from an exhaust port (not shown) communicating with the exhaust space 18 via the dust collection filter 24, the communication port 19, the communication space 17, the air passage port 20, and the exhaust space 18. The dust sucked in with the airflow from the suction port 28 is stored in the dust collection chamber 16 by the dust collection filter 24.

In addition, when a certain amount of dust has accumulated in the dust collection chamber 16 captured by the dust collection filter 24, when disposing of this dust, remove the lid 3 and remove the dust from the opened front opening of the main body case 2. It can also be discarded.

Further, dust accumulated in the dust collection chamber 16 can be removed by a separate large-sized vacuum cleaner. To remove this dust, slide the handle 41 forward and
When the display 37 of [1] is set to the position indicating it, the first opening 31 communicates with the flow port 35 on the handle 41 side, as shown in FIG. Also, the second
When the opening 32 is almost closed, the switch 51 is turned off, and the electric blower 23 is turned off, that is, stopped. Furthermore, when the suction side end 45 of the suction pipe 44, which is connected to the dust collection chamber of a separate vacuum cleaner, is connected to the connection part 43 at the other end of the handle 41, the dust collection chamber 16 and the separate vacuum cleaner are connected. is communicated with the dust collection chamber through a handle 41 and a suction pipe 44. In this state, when the electric blower of a separate vacuum cleaner is driven, as shown by the arrow in FIG.

In addition, hand-held vacuum cleaners are convenient and suitable for cleaning narrow spaces, but as described above, when sucking dust from the suction port 28 of hand-held vacuum cleaners, a separate large vacuum cleaner is required. Using the suction power of a shaped vacuum cleaner, you can perform powerful dust extraction.

According to the configuration of the above embodiment, instead of connecting the suction port 28 to a suction port facing the dust collection chamber of a separate vacuum cleaner, the first suction port 28 is formed separately from the suction port 28.
Since the opening 31 is selectively communicated with a separate vacuum cleaner so that the dust accumulated in the dust collection chamber 16 can be sucked out by the separate vacuum cleaner, the shape of the suction port 28 can be freely set. can do. Therefore, the suction port 28 can be enlarged, and even large dust particles can be sucked in, and cleaning can be performed efficiently.

In addition, the handle 41 may be fixed to the vacuum cleaner body 1, and the closure body 34 for opening and closing the first and second openings 31 and 32 may be provided independently of the handle 41, but it is possible to provide the closure body 34 to be slidable. By integrally providing the closure body 34 on the handle 41 and interlocking the sliding of the handle 41 with the opening and closing of the first and second openings 31 and 32, the first opening can be opened by simply sliding the handle 41. The second openings 31 and 32 can be selectively opened and closed, making it easy to use.

Furthermore, by linking the sliding of the handle 41 and the on/off of the switch 51, the electric blower 23 is activated only when necessary, especially when a separate vacuum cleaner is used to suck up dust in the dust collection chamber 16. ,
Since the structure is such that the electric blower 23 is always in a stopped state so that the electric blower 23 is never in a driving state, it is even more convenient to use, and misuse can be prevented.

(Effect of the invention) According to the invention, an opening that faces the dust collection chamber and can be opened and closed separately from the suction port is formed in the main body of the vacuum cleaner, and this opening is communicated with one end of the tubular handle. By forming a connection part on the other end of the handle to which the suction pipe of a separate vacuum cleaner is connected, the dust accumulated in the dust collection chamber can be sucked out by a separate vacuum cleaner connected to this suction pipe. The dust accumulated in this dust collection chamber can be disposed of easily and hygienically.
In addition, the opening for sucking up dust with a separate vacuum cleaner is formed separately from the suction port, so the shape of this suction port can be set freely, and the suction port can be enlarged to suck in large amounts of dust. It can be done.
