Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention applies a high voltage between a cathode plate and an ionizing line,
This invention relates to an ion blowing device that obtains a blowing effect by causing corona discharge in ionized wires.

Conventional technology The technique of applying a high voltage between the cathode plate and the ionized wire to generate a corona discharge in the ionized wire to obtain an air blowing effect is well known, and many applied technologies have been developed (for example, in the literature As, Deguchi and others: 5ANYOTECHN
ICAL REVIEW VOL, 4 /ra 1
1972).

However, in the above-mentioned corona discharge blowing structure, electrostatic attraction is generated between the ionization wire and the cathode plate during the discharge, and a phenomenon occurs in which each ionization wire vibrates due to the action of the attraction and the action of the tension of the ionization wire. It was something.

Problems to be Solved by the Invention In this way, when each ionization line vibrates, a vibration sound is generated from each ionization line, and in particular, if the length of each ionization line is the same, the frequency of the vibration sound is approximately Since they are equal, the mutual vibration sounds overlap, eventually causing a problem of generating a humming sound.

In addition, the above-mentioned humming noise is transmitted to the outer box of the blower body,
This is also the cause of resonance noise generated from the outer box, and is also due to the problem of not being able to obtain the ion ventilation effect, which is characterized by silence.

In view of the above-mentioned conventional problems, one of the objects of the present invention is to suppress the humming noise phenomenon caused by the interaction of ionized lines and to obtain a quiet air blowing effect.

Means for Solving the Problems In order to solve the above problems, the present invention arranges the ionization lines so that the lengths of adjacent ionization lines vary.

Effect: With this configuration, the vibration frequencies generated from adjacent ionization lines do not match because their lengths are different, and no beat noise is generated.

EXAMPLE Hereinafter, the present invention will be explained with reference to the accompanying drawings showing one example thereof.

In the figure, 1 is a blower main body, and an inlet 2 and an outlet 3 are provided on opposing surfaces. Reference numeral 4 denotes cathode plates made of aluminum, for example, and a plurality of cathode plates are arranged at a constant distance. Each cathode plate 4 has a lower end supported by a support base 5 made of an insulator, and an upper end electrically connected by a connector 6. In addition, this connector 6 may be used as necessary.
may have a supporting function for each cathode plate 4. Reference numeral 7 denotes ionization wires arranged in pairs with each cathode plate 4 at a predetermined distance, and are made of tungsten, for example, and are arranged while maintaining a distance from adjacent ionization wires 7. The lower ends of each ionized line 7 are connected to spacers 8a and 8b.
It is fixed to a support base 9 made of an insulator via a support plate 9, and its upper end is electrically connected by a connector 10. Further, this connecting tool 10 is fixed to the blower main body 1 so that each of the above-mentioned I/Os 7 is supported with a constant tension. Here, the spacers 8a and 8b are set so that their lengths are alternately longer or shorter.

Therefore, the lengths of the adjacent ionized lines 7 are also two types, 11 and 42, and the ionized lines 7 having the same length are arranged so as not to be adjacent to each other.

In addition to the above-mentioned components, the blower main body 1 includes a switch 11 for operation control, and a power source 12 whose anode and cathode are connected to the connector 10 and the connector 6 through the switch 11, respectively. Equipped with:

In the above configuration, when the switch 11 is turned on and a corona discharge is caused in the ionized wire 7, ventilation is performed from the ionized wire 7 to the cathode plate 4 side as shown by the arrow, and as a result, the air outlet a is opened from the suction port 2. An air current is created to exit.

In this state, each ionization line 7 vibrates, but the frequency is different between adjacent ionization lines 7 because their lengths 11 and 12 are different.

Therefore, adjacent ionized lines 7 do not resonate, and quiet air can be blown throughout. As a result, the resonance of the outer box part of the blower main body 1 can also be suppressed, and considerations in the material setting and design of the outer box part can also be reduced.

In addition, in this example, the length of the ionization line 7 is E
Although there are two types, l and l12, it is not limited to these.
Similar effects can be expected even if the lengths of the three types or all of the ionization lines 7 are changed.

Effects of the Invention As is clear from the above embodiments, the present invention can suppress mutual resonance between ionized lines by arranging adjacent ionized lines so that the lengths of adjacent ionized lines are different. The accompanying humming noise can also be suppressed, and the quick configuration enables quiet ventilation. In addition, the resonance of the outer box caused by this can be suppressed, and the overall effect is that quieter air blowing is possible.
