ものである。However, in the above-mentioned conventional suction-type vacuum cleaner, since dust is sucked by an electric blower and collected by a dust collection filter, finer dust than the dust collection filter is discharged to the outside. There was a problem that would. As a countermeasure, dust can be suppressed by making the dust filter finer, but the pressure loss in the dust filter becomes extremely large, and the motor of the electric blower must be a high output motor. . However, this may be a countermeasure that households with infants and the sick use a vacuum cleaner with a larger output than necessary. Such a vacuum cleaner is expensive and requires high maintenance costs.

するのはかなり難しいものであった。On the other hand, in the conventional exhaust circulation cleaner as shown in FIG. 9, although the above-mentioned problem of the suction cleaner can be avoided, the positive pressure exhaust is returned to the suction nozzle. There is a problem that the suction power is insufficient to collect the hair or pet hair that is electrostatically adsorbed on the surface of the mat or flooring due to the narrowing of the strong suction area (high negative pressure area). . As a countermeasure against static electricity, there has been a proposal to provide a static elimination unit in the suction nozzle in the past to eliminate static electricity. Met. As described above, the exhaust-circulation-type vacuum cleaner has an advantage that the output of the electric blower 39 can be relatively small. It was quite difficult to suck up the dust that was being made.

As a result, in the fan casing 7, air is drawn from the suction fan suction port 9 as indicated by an arrow a, and exhaust is performed from the suction fan discharge port 11 as indicated by an arrow b. Due to this suction, a negative pressure is generated in the dust collection chamber 5, suction is performed from the suction nozzle 2 through the nozzle joint 3, and exhaust from the suction fan discharge port 11 is supplied to the first exhaust passage as shown by an arrow c. 12 and is blown into the suction nozzle 2. The blown exhaust air (hereinafter referred to as circulating wind) causes dust (not shown) scattered on the floor surface 1 to float, and at the same time, is sucked into the dust collecting chamber 5 again through the nozzle joint 3, and only the dust is collected by the dust filter 6 and the circulating wind repeats the exhaust circulation. In addition, when the surface to be cleaned is near a wall in a room or the like and where the intake power at the corner is likely to be insufficient, a part of the circulating wind may be discharged to the outside of the cleaner in order to improve the suction performance.

In addition, the dust that could not be collected in the first suction chamber 17 is collected again in the second suction chamber 18 by the traveling of the suction nozzle 2 to improve the dust collection ability. . Also, as a second reason, it is possible to prevent leakage of the circulating air from the suction nozzle 2 by separately sucking the circulating air reflected in various directions after being blown onto the floor surface 1 in the front and rear two chambers. can give. For example, if the first blowing part 16 is provided at the head of the suction nozzle 2, the flow in front of the first blowing part 16 will leak to the outside, but the first blowing part 16 is provided in the middle of the suction nozzle 2. This makes it possible to prevent leakage.

There are various types such as carpets, PVC mats, etc., and the dust scattered there is also a wide variety, such as sand and dust, body hair of humans and pets, lint of chemical fibers such as cotton, wool, acrylic, and food fragments. Things exist. The combination of the floor surface 1 and the dust makes it possible to form a combination of human hair and pet hair on a PVC mat, nylon lint on a polypropylene carpet, and the like. In such a low-temperature and low-humidity environment, static electricity due to frictional charging or peeling charging is generated between the floor 1 and the dust, and the dust is attracted to the floor 1 so that the dust is collected by the cleaner. It becomes very difficult to do. In particular, the exhaust circulation type vacuum cleaner returns the positive pressure circulating air to the suction nozzle 2, so that the negative pressure area in the suction nozzle 2 is relatively narrow. Or remove static electricity.

ことができるからと考えられる。As described above, the neutralization action of the first neutralization member 23 depends on the conductive material constituting the first neutralization member 23. Another position for performing static elimination in the suction nozzle 2, that is, its installation position Is also greatly affected. The present inventors have examined the charge distribution in the suction nozzle 2 and obtained an interesting finding that the place where the amount of static electricity is the largest is near the first spraying section 16. This is the first spraying part 1
The temperature of the circulating air blown out from the room 6 is higher than the normal temperature due to the exhaust heat of the motor 10 and the like. It is thought to be from. And after careful examination,
The most effective position for installing the first static elimination member 23 is
It is on the wall surface inside the first suction chamber 17 at a position near the front of the first blowing section 16. The reason is that the circulating air is blown out from the first blowing unit 16 to eliminate static electricity before further charging is applied, and the dust attached by the static electricity is caused to float by the dynamic pressure of the circulating wind,
This is considered to be because dust collection is promoted and static electricity caused by the circulating wind itself can be prevented by the first static elimination member 23 provided in the vicinity.

First suction chamber 17
Dust is relatively likely to remain on both sides, but this makes it possible to efficiently wind up the dust on both sides, and to achieve a well-balanced dust collection.

The rotating brush 30 may be provided with a small motor (not shown) inside the suction nozzle 2 and connected and rotated by a timing belt or the like. Alternatively, the rotating brush 30 may use the circulating wind blown by the second blowing unit to generate wind. It may be rotated. By applying the impact force due to the rotation of the rotating brush 30, dust mixed in the carpet can be scraped out, and the dust collecting performance is further improved.

床面との接触点から第１除電部材２３まで距離は１５〜
２０ｍｍ程度に設定するのが好ましい。When the rotary brush 30 is installed in the first suction chamber 17, the capacity of the first suction chamber 17 needs an extra capacity corresponding to the installation of the rotary brush 30, but the capacity of the first suction chamber 17 is large. It is preferable to make the value as small as possible. The reason is that if the capacity of the first suction chamber 17 is large, the wind speed in the first suction chamber 17 decreases. However, when the size is excessively reduced, the rotating brush 30 is too close to the first static elimination member 23,
Dust of a relatively large size cannot be collected. Therefore, it is necessary to provide an appropriate distance between the rotating brush 30 and the first static elimination member 23. For example, if the rotating brush 30 has a diameter of about 30 mm, contact between the rotating brush 30 and the floor surface is not possible. The distance from the point to the first static elimination member 23 is 15 to
Preferably, it is set to about 20 mm.
