(First embodiment)
A best first embodiment for carrying out a vacuum cleaner according to the present invention will be described with reference to FIGS. 1 to 3.

  The vacuum cleaner of the first embodiment includes an electric blower 2 that sucks air into the cleaner body 1 and a dust collection chamber for collecting dust from the air sucked into the cleaner body 1 by the electric blower 2. 3, a paper pack 4 mounted in the dust collection chamber 3 for collecting dust, a paper pack holder 5 for mounting the paper pack 4 in the dust collection chamber 3, and a mist generator for generating a mist 18 6 and a wheel 7 for moving the cleaner body 1 (see FIG. 1).

  On the upper part of the vacuum cleaner main body 1, a lid body 8 is provided so as to be openable and closable so as to open and close the upper portion of the dust collecting chamber 3. Wheels 7 are provided at the lower part of the cleaner body 1 so that the cleaner body 1 can be moved while placed on the floor. A suction port 9 is opened on the front surface of the cleaner body 1, and a hose 10 communicating with a floor suction tool (not shown) is connected to the suction port 9. A communication port 11 communicating with the electric blower 2 is formed on the inner wall surface on the downstream side of the dust collection chamber 3 (see FIG. 1).

  The downstream side of the electric blower 2 is divided into a first exhaust passage 12 and a second exhaust passage 13 having a narrower passage than the first exhaust passage 12. The first exhaust passage 12 communicates with a first exhaust port 14 formed on the rear side surface of the cleaner body 1. The first exhaust port 14 opens upward, and a first filter 15 is disposed on the upstream side of the first exhaust port 14. The second exhaust passage 13 communicates with a second exhaust port 16 having an upper opening formed on the rear upper surface of the cleaner body 1. A second filter 17 is disposed on the upstream side of the second exhaust passage 13. A mist generator 19 that discharges the mist 18 generated by the mist generator 6 faces the second exhaust flow path 13 between the second filter 17 and the second exhaust port 16 (see FIG. 1).

  When cleaning, an operation unit (not shown) is operated to operate the electric blower 2, and the air sucked into the dust collecting chamber 3 by the electric blower 2 through the suction port 9 is removed by the paper pack 4, and the electric blower After passing through 2, the electric blower 2 is cooled and then exhausted out of the cleaner body 1 through the first exhaust port 14 and the second exhaust port 16.

  An operation unit (not shown) is provided with a mist discharge mode for discharging the mist 18 into the room before cleaning. When the mist discharge mode is selected, the electric blower 2 performs a weak operation and the mist generator 6 is activated to release the mist 18 into the room through the second exhaust port 16 as shown in FIGS. The The mist 18 released into the room adheres to the dust 20 scattered or floating in the air. And since the dust 20 to which the mist 18 adhered becomes heavy, it falls to the floor surface (see FIG. 3). The dust 20 to which the mist 18 falling on the floor is not scattered again in the air until the mist 18 is dried. Since the mist 18 adheres to the dust falling on the floor surface in the same manner as the dust 20 in the air, it does not scatter in the air until the mist 18 dries.

  When a predetermined time elapses after selecting the mist discharge mode (approximately 5 minutes in the first embodiment), the operation unit is operated to perform normal cleaning. At this time, the dust 20 scattered or floating in the air is dropped on the floor by the mist 18 and the dust falling on the floor is not likely to be scattered in the air by the mist 18. You can clean the entire room just by cleaning the surface. In addition, since it is not necessary to clean the dust 20 that has been scattered or suspended in the air falling on the floor after completion of cleaning, it is possible to simplify the cleaning effort.

  When the mist discharge mode is selected, the reason why the electric blower 2 is operated weakly is to make the noise as low as possible, and a person who does not care about the noise can switch to the strong operation. The mist generated from the mist generating device 6 on the dust contained in the air that has passed through the electric blower 2 by disposing the second filter 17 upstream of the mist generating portion 19 of the second exhaust flow path 13. It is possible to prevent a reduction in the amount of mist released to the outside of the cleaner body 1 due to the adhesion of 18.

  Since the second exhaust port 16 is formed upward, the mist 18 can be efficiently discharged into the room. Moreover, since the mist 18 can be discharged out of the cleaner body 1 using the exhaust air of the electric blower 2, it is not necessary to provide a blowing means in the mist generating device 6, and the configuration can be simplified. Further, since the second exhaust flow path 13 is formed narrow and the amount of air flowing through the second exhaust flow path 13 can be reduced, the second exhaust flow path is formed by the suction of dust and the flow of air that has passed through the paper pack 4. It is possible to suppress the dust from adhering to the inside 13 and to suppress the decrease in the amount of mist 18 released from the cleaner body 1 due to the mist 18 adhering to the dust adhering to the second exhaust passage 13. it can.

  In the first embodiment, the mist 18 is discharged to the outside of the cleaner body 1 using the exhaust air generated by the electric blower *, but is not limited to this configuration. You may make it the structure which makes the mist generator 6 comprise a ventilation function and discharges the mist 18 out of the cleaner body 1.

  In the first embodiment, exhaust air from the electric blower 2 is exhausted from the first exhaust port 14 and the second exhaust port 16 at the same time. However, in the second embodiment, the first exhaust is performed by the louver 21 constituting the flow path switching means. One of the flow path 12 and the second exhaust flow path 13 is selectively closed.

  As shown in FIG. 4, the exhaust from the electric blower 2 passes through the second filter 17. The exhaust from the electric blower 2 that has passed through the second filter 17 can communicate with the first exhaust passage 12 and the second exhaust passage 13. A louver 21 that selectively closes either the first exhaust flow path 12 or the second exhaust flow path 13 is rotatable at a substantially intermediate position between the first exhaust flow path 12 and the second exhaust flow path 13. It is arranged. The louver 21 is rotated by a motor (not shown). Usually, the second exhaust passage 13 is held at a position to close it.

  When the mist discharge mode is selected, the electric blower 2 performs a weak operation, and when the louver 21 is rotated to a position where the first exhaust passage 12 is closed, the mist generating device 6 is activated and as shown in FIG. Mist 18 is discharged into the room through the second exhaust port 16. When a predetermined time elapses after the mist discharge mode is selected, the operation unit is operated to perform normal cleaning. At this time, the louver 21 rotates to a position where the second exhaust passage 13 is closed. As a result, the air that has sucked the dust and passed through the paper pack 4 does not flow into the second exhaust flow path 13, thereby preventing the dust from adhering in the second exhaust flow path 13 such as the mist generating unit 19. It is possible to prevent a reduction in the amount of mist 18 released from the cleaner body 1 due to the mist 18 adhering to the dust adhering to the second exhaust flow path 13 (see FIG. 5).

Both the first exhaust port 14 and the second exhaust port 16a are inclined upward (see FIG. 6).

Since the upper part of the second exhaust port 16a is not opened, the dust 20 in the air does not accumulate in the vicinity of the second exhaust port 16a, and the amount of mist 18 released to the outside of the cleaner body 1 by the accumulated dust. A decrease can be prevented. Further, since the first exhaust port 14 opening upward is formed at the lower position of the second exhaust port 16a, the mist 18 discharged from the second exhaust port 16a as shown in FIG. Since it can be diffused also by the exhaust from 14, the mist 18 can be efficiently diffused throughout the room with a simple configuration.
