Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a positive / negative ion amount measuring apparatus. More specifically, the present invention relates to an ion amount measuring apparatus that measures the amount of positive and negative ions contained in the atmosphere at the same place and continuously displays the positive and negative ion amounts and the difference between the positive and negative ion amounts.
[0002]
[Prior art]
In the conventional positive / negative ion amount measuring apparatus, a method of separately measuring positive and negative ions by switching the polarity of the applied power to the electrodes has been performed.
[0003]
Japanese Patent Laid-Open No. 8-62180 discloses an apparatus capable of simultaneously measuring positive and negative ion amounts.
[0004]
All of the above are used to measure the positive / negative balance of ions generated by an ion generator, and do not measure the general state of ions in the atmosphere.
[0005]
[Problems to be solved by the invention]
In order to know the ion state in the air inside and outside the room, it is necessary that the measurement position is not limited in addition to being configured so that the amount of positive and negative ions can be detected simultaneously.
[0006]
The method of switching the polarity of the electrodes described above does not measure the amount of positive and negative ions at the same time. For example, since negative ions are not measured when measuring positive ions, the atmosphere in which generation and annihilation are repeated every moment It is unsuitable as a device that measures the amount of positive and negative ions at the same time.
[0007]
In addition, the apparatus disclosed in Japanese Patent Application Laid-Open No. 8-62180 is arranged in front of the ion generator, and the amount of positive and negative ions is measured by bringing the ion wind discharged from the ion generator into contact with the electrode. Therefore, it is not suitable for use in measuring the amount of positive and negative ions unevenly distributed in the atmosphere. In particular, this apparatus employs a structure in which two electrode plates are arranged in a separated state or spirally on the same plane of a frame made of an insulating material. As described above, depending on how the ion wind (ionized air) is blown, there still remains a problem that the measured data varies.
[0008]
In view of the above, the present invention clearly provides a positive / negative ion amount measuring apparatus capable of simultaneously measuring positive and negative ion amounts at any position in the atmosphere without causing variations in the data. The task is to do.
[0009]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, according to the attached drawings, a positive / negative ion amount measuring apparatus according to the present invention will be described.
[0011]
In FIG. 1, reference numerals 10 and 20 denote detectors, which are respectively provided in metal or plastic housings 11 and 21 with electrode cylinders 12 and 22 supported by insulating rings and collector electrodes 13 supported by insulating columns. And 23, and according to the rotation operation of the fans 14 and 24, the air is sucked from the inlets 15 and 25 to the rear end side where the air is sucked. The inlets 15 and 25 of the housings 11 and 21 can be shielded by caps 16 and 26, respectively.
[0012]
The fans 14 and 24 are adjusted to have the same work amount.
[0013]
The electrode cylinder 12 and the collector electrode 13, and the electrode cylinder 22 and the collector electrode 23 are arranged as a pair, and the applied electrodes are different. When the electrode cylinder 12 is applied positively, the collector electrode 13 is negative, the electrode cylinder 22 is negative, and the collector electrode 23 is positively applied. When air is sucked by the rotation of the fans 14 and 24, positive ions contained in the air are adsorbed to the negative collector electrode 13, and the negative ions pass without being adsorbed to the collector electrode 13, and the negative ions are The positive ions are adsorbed by the positive collector electrode 23, and the positive ions pass through without being adsorbed by the positive collector electrode 23. Since there is a difference in the current value flowing through the collector electrodes 13 and 23 depending on the amount of ions adsorbed, each current value is transmitted to the microcomputer via the current-voltage conversion circuit, automatic zero adjustment circuit, and A / D conversion circuit. Is entered as In the microcomputer, various calculations are performed, and the difference between the number of positive ions, the number of negative ions, the total number of ions, and / or the number of positive and negative ions is displayed digitally or graphically in monochrome or color.
[0014]
The electrode cylinder 12 and the collector electrode 13, and the electrode cylinder 22 and the collector electrode 23 are accommodated in the housings 11 and 21 as a pair, respectively, and are configured not to be affected by external electromagnetic waves between or in the vicinity.
[0015]
Zero adjustment can be performed under the same conditions for both positive and negative ions by stopping the fans 14 and 24 and shielding the inlets 15 and 25 with caps 16 and 26. After zero adjustment, if the caps 16 and 26 are removed and the fans 14 and 24 are operated, positive and negative ions can be measured under the same conditions.
[0016]
Although the housings 10 and 20 are shown separated from each other in the drawing, in an actual apparatus, at least the inlets 15 and 25 of the housings 11 and 21 are arranged as close as possible. It is not preferable that the inlets 15 and 25 are arranged at positions far away from each other because the condition that the air to be taken in (measured air) is “the air at the same place” is not satisfied.
[0017]
Furthermore, in this invention , as shown in FIG. 2, the air intake unit 30 is arrange | positioned in the front surface of the housing 11 * 21. The air intake unit 30 includes an air introduction pipe 31 and branch pipes 32 and 33, and valves 34 and 35 are disposed in the branch pipes 32 and 33, as necessary. At the ends of the branch pipes 32 and 33, a connection or fixing mechanism 36 for joining to the inlets 15 and 25 of the housings 11 and 21 of the apparatus shown in FIG. The connection (fixing) mechanism 36 may be prepared at the inlets 15 and 25 of the housings 11 and 21 shown in FIG. Alternatively, the air intake unit 30 may be formed integrally with the housings 11 and 21 in advance.
[0018]
As the valves 34 and 35, for example, various valves of a manual opening / closing system or an electric opening / closing system are used, and the two valves can be operated in synchronization or independently. That is, both the valves 34 and 35 can be operated simultaneously in an open state or a closed state, or, for example, both can be operated separately in a state where the valve 34 is opened or the valve 35 is closed. .
[0019]
The configuration and function of the valves 34 and 35 can also be performed by switching the air passage, such as a three-way valve.
[0020]
Member and valve 34, 35 to the switching valve or the like to form the air intake unit 30, that make up a material, such as positive and negative ions contained in the air passing through the inside does not give something like of influence (e.g., adsorption).
[0021]
By using the air intake unit 30 described above, it is possible to take in air at an extreme position and simultaneously measure the amount of positive and negative ions contained in the air.
[0022]
【The invention's effect】
According to the positive / negative ion amount measuring apparatus according to the present invention, it is possible to suck the atmosphere at the same selected place and simultaneously measure and display the positive / negative ion amount contained in the atmosphere. The problem is solved. In particular, the amount of positive and negative ions can be measured not only simultaneously, but also the intake of air to be measured can be set to the extreme position, so that the amount of positive and negative ions localized (distributed) in the atmosphere can be accurately measured. There are advantages that can be made.
