Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner used at home.

[0002]

2. Description of the Related Art In recent years, the simplification of the dust collecting method of an electric vacuum cleaner has become remarkable, and an electric vacuum cleaner of a type in which a dust collecting bag is used as a paper bag for more effective cleaning has become mainstream.

Conventionally, this type of vacuum cleaner has generally been constructed as shown in FIG. The configuration will be described below with reference to the drawings.

As shown in the figure, the electric vacuum cleaner 1 has a motor chamber 3 containing a suction motor 2 and a dust collecting chamber 5 containing a paper dust bag 4, and the dust bag 4 is It was attached to the suction port 6 of the dust collection chamber 5.

In the above structure, when the electric vacuum cleaner 1 is operated, the motor 2 generates a suction force to suck the dust, and the dust bag 4 made of paper captures only the dust and the filtered clean air is generated. Vacuum cleaner 1 after cooling the inside of the motor 2
The dust will be discharged to the outside of the main body and collected in the dust collecting bag 4.

[0006]

In such a conventional vacuum cleaner, the suction motor has a high output as the power of the vacuum cleaner has been increased along with the recent increase in power of the vacuum cleaner. It is becoming more common to inhale a lot of fine dust. Furthermore, since the motor has a high air volume, the suction speed was fast, and the fine dust was strongly caught in the dust bag's eyes and easily clogged. When fine dust clogs, even if the dust bag is not yet full, the pressure drop due to a large pressure loss due to the clogging of the motor causes the suction force to rapidly decline. Therefore, the dust bag had to be changed frequently, and the usability and maintainability were not sufficient.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric vacuum cleaner with which the dust collecting bag is unlikely to be clogged even when fine dust is sucked, the suction force is sustained, and the usability and maintainability are good. And

[0008]

The first means of the present invention for achieving the above object has a motor chamber containing a suction motor and a dust collecting chamber containing a dust bag. An oscillator is provided at the front of the dust chamber, and a piezoelectric vibrator is provided at the rear of the dust bag.

The second means is to have an oscillator and a piezoelectric vibrator inside a dust collection chamber with a dust collection bag sandwiched vertically.

The third means comprises an electromagnetic vibrator in contact with the lower part of the dust bag in the dust collection chamber.

[0011]

In the first means of the present invention described above, an oscillator is provided at the front of the dust collecting chamber, and a piezoelectric vibrator is provided at the rear of the dust collecting bag so that dust can be removed from the dust collecting bag by vibrating the vibrator. Sieve off and reduce clogging of dust bag.

Similarly, in the second and third means, dust is sifted from the dust collecting bag by vibration to reduce clogging of the dust collecting bag, and the vibrator is used for a long time regardless of the disposal of the dust collecting bag. Can be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, the electric vacuum cleaner 7 has a motor chamber 9 containing a suction motor 8 and a dust collecting chamber 11 containing a dust bag 10, and the dust bag 10 is provided in the dust collecting chamber 11. It is attached to the suction port 12. In FIG. 1, a sound wave oscillator 13 is provided in the front part of the dust collecting chamber 11, and a piezoelectric vibrator 14 is attached to the rear part of the dust collecting bag 10. In FIG. 2, the oscillator 13 is provided above the dust collection chamber 11 with the dust collection bag 10 interposed therebetween, and the vibrator 14 is attached to the lower portion of the dust collection chamber 11. In FIG. 3, a vibrator 15 made of an electromagnetic solenoid is attached to the lower part of the dust collection chamber 11.

In the above structure, when the electric vacuum cleaner 7 is operated, the motor 8 generates a suction force to suck the dust, and the dust bag 10 made of paper captures only the dust, and the filtered clean air is generated. After cooling the inside of the motor 8, the dust is discharged to the outside of the main body of the electric vacuum cleaner 7 and collected in the dust bag 10.

When an alternating current of several tens KHz is applied to the oscillator 13, ultrasonic waves are generated. Since the ultrasonic waves have high directivity, they are radiated to the transducer 14 facing them. Since the vibrator 14 resonates due to the ultrasonic waves and vibrates the dust collecting bag 10, the dust in the dust collecting bag is strongly caught and the clogged dust is removed. Therefore, the suction force is prevented from rapidly declining.

Next, a second embodiment is shown in FIG. Since most of the structure of the electric vacuum cleaner is the same as that of the first embodiment, the same reference numerals are given and the description thereof is omitted. The difference from the first embodiment is that the oscillator 14 is provided on the opposite side of the oscillator with a dust bag inside the dust chamber. A few tens of K for the oscillator 13
By applying an alternating current of Hz, ultrasonic waves are generated, and the oscillator 14 provided facing each other resonates. The dust bag is a vibrator 14
Vibration is transmitted by directly contacting with, and it is possible to remove the clogged dust. Therefore, the dust bag 10
At the same time, it is not necessary to discard the vibrator 14 and the versatility of the dust collecting bag is enhanced.

As shown in FIG. 3, a vibrator 15 of an electromagnetic solenoid is provided instead of the oscillator and the vibrator, and vibration is generated by applying an alternating current to the vibrator 15. Similar to the above, it is possible to remove clogging from the dust bag.

As described above, according to the vacuum cleaner of the present invention, the oscillator is provided in the front part of the dust collecting chamber, and the piezoelectric vibrator is provided in the rear part of the dust collecting bag, so that dust is generated by the vibration of the vibrator. It is possible to reduce the clogging of the dust collecting bag by sieving it from the dust collecting bag.

Further, by providing the vibrators 14 and 15 at positions facing the oscillators in the dust collecting chamber, the vibrators 14 and 15 can be used for a long time regardless of disposal of the dust collecting bag.

[0021]

As is apparent from the above embodiments, according to the present invention, the first means has a motor chamber containing a suction motor and a dust collecting chamber containing a dust bag. An oscillator is provided at the front of the dust collection chamber, and a piezoelectric vibrator is provided at the rear of the dust collection bag. As a second means, the dust collection bag is oscillated by sandwiching the dust collection bag up and down. It has a child and a piezoelectric vibrator. Further, as a third means, an electromagnetic vibrator is provided in the dust collection chamber in contact with the lower part of the dust bag.

Therefore, the vibration of the vibrator sifts dust from the dust collecting bag to reduce clogging of the dust collecting bag.

Further, in the second and third means, the dust is sifted from the dust collecting bag by vibration to reduce the clogging of the dust collecting bag and the vibrator can be used regardless of the disposal of the dust collecting bag. ..

Therefore, even if fine dust is sucked, the dust bag is unlikely to be clogged, the suction force is maintained, the usability and maintainability are good, and the electric vacuum cleaner is excellent in economic efficiency.
