[Fig. 8]

< open-electrode >

Open-electrode is the shape possessing opening portion of cylinder, the plate body being formed with through hole, ring etc.

The length (length of such as cylinder) of opening is related to the intensity of ion wind.

Open-electrode load has positive voltage and becomes positive electrode.The shape circular of cylinder, importantly becomes roughly equidistant from the top as electric discharge position of negative electrode and needle electrode to the edge part of cylinder.When distance is different, then near position, electric discharge is concentrated, hydraulic performance decline.In addition, the possibility of releasing spark uprises and dangerous increase.On those grounds, the conglobate inner edge of shape shape of needle electrode side is preferably placed at.

The combination > of the opposed sparking electrode of < and independent spray point electrode

When arcing distance due to the open-electrode and needle electrode that form opposed sparking electrode changes, the wind-force of generation and negative ion amount, ozone amount change greatly, therefore in order to maintain performance, importantly removing by maintenance the dirt that electrode adheres to.

Mostly dirt is to adhere on open-electrode.Because needle electrode is from point discharge, so the attachment of dirt is little.Mostly the dirt that open-electrode adheres to is in open end edge, and extends to open interior, and the top to needle electrode is close.When arcing distance shortens, then the magnitude of current discharged increases, and can produce discharge noise, spark, electronic noise.The generation of anion also reduces.

Under certain environmental conditions, due to the adhesion amount of dirt can be estimated, therefore, it is possible to safeguard termly.Under the condition that environmental change is large, due to the progress of very difficult estimation dirt, therefore importantly maintenance is detected period.

When the active device of this purification carries out round the clock continuously long time running, along with the process of time, the dirt of the dirt of sparking electrode especially open-electrode becomes obviously (about 4 ~ 5 months), confirm that the minimizing of ionic weight causes the dust in air to remove and smelly eliminating effect goes down, thus develop the method automatically carrying out this detecting.Basic electronic loop, electronic buzzer loop are with reference to the 3rd figure.

These master datas represent that the dirt of sparking electrode causes the increase of discharge current and anion reduces.(with reference to table 2)

Along with discharge current increases, discharge system is gradually from voltolising to corona spark discharge transition, and ion wind also dies down, and smelly eliminating, bacteria-eliminating efficacy also weaken gradually.And the deterioration of electrode also develops because of electric discharge.When environment due to the amount when suspended particulate etc. changes, the progress of hydraulic performance decline also changes, and therefore maintains performance by suitably cleaning electrode.

Detect and opposite electrode adheres to dust and arcing distance shortens thus after the magnitude of current increased, display unit shows.Display unit uses lamp, sound.Display part arrange represent power switch open/close lamp and to the lamp needing information when safeguarding to report to the police, buzzer.

Test example 1

The test > of < negative ion amount change according to the electric discharge number of days of tubular electrode

Ozonograph: Co., Ltd. SEKI ELECTRONICE (Germany) SOL#3500

Confirmed by characteristic curve, although do not see too large change near number of days 60 days, there is large change in ionic weight from about the 90th day, and near 150 days, ionic weight reduces by half.Carried out the cleaning of the 1st sub-electrode dirt at the 150th day, the measurement result of ionic weight confirms that performance recovery is to original numerical value thereafter.

Based on the change of the opening diameter of the dust that open-electrode adheres to and the relation of the magnitude of current as shown in table 2.

After observing internal diameter reduction 3mm, when about 14.8mm, the magnitude of current becomes 2 times, sharply increases thereafter, and internal diameter is increased to the magnitude of current of nearly 4 times when 12.8mm after reducing 5mm.Although this numerical value self is different because of the size etc. of opening diameter, when confirming that the opening diameter of the open-electrode when the attachment because of dust diminishes, then there is the sharply increase of the magnitude of current.

Because the Measuring Time of table 1 and table 2 is common, and to observe at the 90th day negative ion amount be 85%, and electric current increases by 2 times, is about 50% at the 150th day negative ion amount, and the magnitude of current becomes 4 times, and the change being conceived to electric current so known is effective.

This result of the test can confirm, measures discharge current amount, can impel and safeguard before increasing sharp, and can the performance of initial stages of restoration by putting maintenance into practice.
