The dust collecting chamber 5 is provided on the negative pressure side and contains a dust collecting bag 7 for collecting the dust 8 sucked by the suction air. The exhaust air 10 of the electric blower 2 passes through an exhaust filter 41 provided at the rear part of the cleaner body 1 and is discharged to the outside of the cleaner body 1.

  A cover 30 is provided on the upper portion of the cleaner body 1, and the cooling chamber 6 is formed by the cover 30 and the cleaner body 1. In the cooling chamber 6, a control board 28 and heat radiating fins 22 of an electrostatic atomizing unit 21 described later are disposed.

  The dust collection chamber 5 is provided in front of the cleaner body 1 and is provided with a suction port 11 communicating with the dust collection chamber 5.

  The electrostatic atomizing unit 21 is arranged on the upper part of the electric blower chamber 3 so that the discharge electrode 24 is exposed in the electric blower chamber 3 and the radiating fins 22 are exposed in the cooling chamber 6.

  As shown in FIGS. 1 and 2, on the bottom surface of the cleaner main body 1, the charged fine particle water 20 that is communicated with the electric blower chamber 3 and generated by the electrostatic atomizing unit 21 is transferred to the outside of the cleaner main body 1. A discharge port 42 for discharge is provided.

  As shown in FIGS. 2 and 3, the bottom surface of the vacuum cleaner body 1 is provided with a locking portion 46 for locking the suction tool 45 to the vacuum cleaner body 1 when the suction tool 45 is not in use. When the suction tool 45 is hung on the locking part 46 in the state where 1 is raised, the locking part 46 is configured so that the bottom surface of the suction tool 45 faces the discharge port 42.

  As shown in FIG. 4, the electrostatic atomization unit 21 mainly includes a Peltier element 23, a heat radiation fin 22 provided on the heat generation side of the Peltier element 23, and a discharge electrode 24 provided on the cooling side of the Peltier element 23. The high voltage is applied to the discharge electrode 24.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the user operates the cleaner body 1, suction air is generated by the electric blower 2, and dust 8 is sucked into the dust collection bag 7 from the suction port 11 of the cleaner body 1. The sucked dust 8 is collected by the dust bag 7. The exhaust air 10 of the electric blower 2 passes through an exhaust filter 41 provided at the rear of the cleaner body 1 and is discharged to the outside of the cleaner body 1.
