  Next, the operation of the one embodiment will be described.

  As shown in FIGS. 1 to 5, when cleaning, the connecting pipe portion 26 of the hose body 21 is connected to the main body suction port 19 of the cleaner body 12, and the extension pipe is connected to the hand operating portion 27 of the hose body 21. 22 is connected, and the connecting pipe 32 of the floor brush 23 is connected to the extension pipe 22. As a result, the floor brush 23 is communicatively connected to the suction side of the electric blower 18 (through the extension pipe 22, the hose body 21, the main body suction port 19 and the dust collecting portion).

  Then, after the operator connects the power cord e to an outlet such as a wall surface, the operator grips the grip portion 28 and operates the desired setting button 29 to operate the electric blower 18 through the main body control portion. In addition to starting in the mode, the control means 65 drives the ion generator 67 to generate ions I by corona discharge at the electrode 67a. For this reason, by driving the electric blower 18, negative pressure sequentially acts on the dust collecting part, the main body suction port 19, the hose body 21, the extension pipe 22 and the floor brush 23, and the ion I generated by the ion generator 67. Is discharged from the discharge hole 68 to the outside of the case body 31 (floor brush 23), that is, to the outside air. The discharged ions I electrically neutralize the dust contained in the outside air, thereby preventing the dust from adhering to the surface to be cleaned due to electrification and adhering to the outer surface of the case body 31. By electrically neutralizing the dust, the dust can be easily peeled off from the outer surface of the case body 31. Further, the operator places the floor brush 23 on the surface to be cleaned and runs forward and backward, thereby sucking dust with air from the suction port 46 and generating dust and ions in the air from the dust suction ports 47 and 47. Ions I generated by the vessel 67 are sucked together with air.

  The dust sucked into the floor brush 23 together with air is sucked into the dust collecting section through the connecting pipe 32, the extension pipe 22, the hose body 21, and the main body suction port 19 while being electrically neutralized by the sucked ions I. As a result, particularly fine dust (fine dust) is prevented from adhering to the connecting pipe 32, the extension pipe 22, the hose body 21 and the like due to charging. The dust sucked into the dust collecting part is separated from the air and collected by the dust collecting part. In addition, the air separated from the dust is sucked into the electric blower 18, and after cooling the electric blower 18, the air is exhausted to become exhaust air and exhausted to the outside of the cleaner body 12.

  In this cleaning, the user rotates the rotating brush 49 by operating the setting button 29 as necessary, for example, when the type of the surface to be cleaned is flooring. Specifically, when the control means 65 drives the electric motor 61, the rotating brush 49 connected to the rotating shaft 61a of the electric motor 61 via the belt 62 rotates forward in the suction chamber 41.

  At this time, the rotating brush 49 sweeps the dust on the surface to be cleaned by each first bristle brush 58b of each first cleaning unit 58 and each second bristle brush 59b of each second cleaning unit 59, and each By removing the static electricity from the surface to be cleaned by each static eliminating brush 59c of the second cleaning unit 59 coming into contact with the surface to be cleaned, dust is prevented from adhering to the surface to be cleaned due to electrification.

  Further, as shown in FIG. 2, a part of the ions I sucked into the suction chamber 41 from the dust suction ports 47 and 47 pass through the suction chamber 41 from the rear of the rotation brush 49 along with the rotation of the rotation brush 49. Connected after being carried to the lower rear via the upper and the front, making it easy to peel off the inner wall of the suction chamber 41 by electrically neutralizing the dust inside the suction chamber 41, especially the windows 48, 48, etc. Flows to tube 32.

  When cleaning is completed, the user operates the setting button 29 (FIG. 5) so that the main body control unit stops the electric blower 18 and the control means 65 stops the ion generator 67. In addition, when the electric motor 61 (rotating brush 49) is driving, the control means 65 also stops the electric motor 61 (rotating brush 49).

  As described above, according to the above-described embodiment, the ion generator 67 that generates the ions I for static elimination is disposed outside the case body 31 on the upper side of the case body 31, and the rotating brush 49 is disposed on the case body 31. The rotating brush 49 protrudes from the outer periphery of the shaft portion 51 that is rotatably supported by the case body 31, and each of the bristle brushes 58b and 59b that sweeps dust on the surface to be cleaned, and the shaft The outer surface of the case body 31 is electrically neutralized with the ions I generated by the ion generator 67 by discharging the brush 59c that discharges the surface to be cleaned. In addition, the attached dust is easily neutralized by the ions I to make it easy to peel off, and the dust can be effectively prevented from adhering to the surface. The surface to be cleaned is neutralized by the neutralizing brush 59c of the rotating brush 49. Then To, the attached dust is easily peeled off by electrically neutralized by ions I, can be effectively prevented adhesion of dust due to charging.

  Further, the dust suction ports 47 and 47 communicating with the suction port 46 (suction chamber 41) of the case body 31 are formed, and the rotating brush 49 is rotated in the direction in which the upper part moves from the rear side to the front side, that is, forward. Thus, the ions I sucked together with the outside air from the respective dust suction ports 47 are rotated by the rotation of the rotating brush 49 so that the ions I are more spread over the entire suction chamber 41 and the entire rotating brush 49 from the rear part to the upper part, the front part and the lower part. Thus, dust can be effectively prevented from adhering to the inside of the suction chamber 41 and the entire rotating brush 49, that is, the shaft 51, the bristle brushes 58b and 59b, the static eliminating brush 59c, and the like.

  Therefore, the appearance of the surface to be cleaned and the floor brush 23 can be kept clean.

  In addition, the dust on the inner and outer surfaces of the windows 48 and 48 is less likely to adhere, so the user can reliably see the rotating brush 49 from above through the windows 48 and 48 during cleaning, improving the appearance. it can.

  When the vacuum cleaner 11 is provided with the floor brush 23 having the rotating brush 49 provided with the charge eliminating brush 59c, particularly when cleaning the surface to be cleaned such as flooring which is difficult to remove dust due to electrification and easily retains fine dust. In addition, the ions I generated by the ion generator 67 are electrically neutralized to facilitate separation of the dust from the surface to be cleaned, and the surface to be cleaned is surely discharged by the neutralizing brush 59c, thereby removing dust. Adhering to the surface to be cleaned can be prevented, and the cleaning performance can be improved. In addition, since the dust is electrically neutralized by the ions I generated by the ion generator 67, the sucked dust adheres to the inner surface of the extension tube 22 due to charging, or the charged dust is charged by the hand operating unit 27. It is possible to prevent undesired electrical influences on the electric part including the setting button 29 and the like.

  In the above-described embodiment, the rotating brush 49 is not only configured to be manually driven and stopped, but the floor brush 23 is provided with a surface to be cleaned detecting means, and the surface to be cleaned detected by the surface to be cleaned detecting means. For example, it may be configured to be automatically driven only when the type is flooring or the like, or may be configured to be rotationally driven and stopped simultaneously with the driving and stopping of the electric blower 18.

  Furthermore, the electric vacuum cleaner 11 is not limited to the canister type, and can be used corresponding to a so-called upright type in which a floor brush 23 is connected to the lower part of the vacuum cleaner main body 12 that is long in the vertical direction, for example. .
