Definitions
- the present invention relates to an ion generator having a function of detecting generated ions.
- an ion generator such as an air purifier
- an ion generator that generates positive ions and negative ions is disposed in the middle of an internal air passage so that the generated ions are discharged together with air into an external space. It has become.
- the ions that charge the water molecules in the clean air inactivate suspended particles in the living space, kill the suspended bacteria, and denature odor components. Therefore, the air in the entire living space is cleaned.
- a standard ion generator generates a corona discharge by applying a high-voltage alternating current drive voltage between a needle electrode and a counter electrode, or between a discharge electrode and a dielectric electrode, thereby generating positive ions and negative ions. Is generated.
- the discharge electrode is worn by sputter evaporation accompanying corona discharge. Further, foreign substances such as chemical substances and dust are accumulated on the discharge electrode. In such a case, the discharge becomes unstable and it is inevitable that the amount of ions generated decreases.
- the ion generator described in Patent Document 1 the presence or absence of ions is detected, and when it is detected that no ions are generated, the user is informed that the ion generator needs to be maintained.
- the ion generator is provided with an ion detector in order to detect whether or not ions are generated.
- An ion detector is provided so that it may face a ventilation path with an ion generator, an ion generator is arrange
- the ion generator and the ion detector are arranged side by side along the air blowing direction in the air blowing path. Positive ions and negative ions generated from the ion generator flow toward the ion detector in the lee by the wind from the blower.
- the ion detector collects and detects either positive ions or negative ions.
- ions passing through the ion detector pass at a certain speed, it is difficult to capture the ions with the ion detector. for that reason. Even though ions are sufficiently generated, the ion detector may detect a small number of ions and erroneously detect that no ions are generated.
- an object of the present invention is to provide an ion generation device that can prevent erroneous detection that ions are not generated despite the generation of ions by reliably detecting the generated ions.
- the present invention includes an ion generator that generates ions, an ion detector that detects the generated ions, a blower that blows out the generated ions to the outside through a blower path, and a control unit that drives and controls the ion generator and the blower.
- the control unit is configured to stop the blower and execute ion detection by the ion detector to determine whether or not ions are generated.
- the ion detector can detect a high concentration of ions immediately after they are generated. For this reason, if ions are generated, they can always be detected, and erroneous determination that ions are generated but ions are not generated can be eliminated.
- the control unit performs ion detection at the start of operation. At this time, ion detection is performed while the blower is stopped. Even if the blower is not operated immediately after the start of operation, the user does not feel uncomfortable. Moreover, when no ions are generated, it can be detected early.
- the controller performs ion detection at a predetermined timing during operation, and when the occurrence of ions is detected a predetermined number of times, stops the blower and executes ion detection. By performing ion detection a plurality of times during operation, the determination accuracy can be improved. When the final determination is made, the blower is stopped, the influence of the wind is eliminated, and the presence or absence of ions is detected.
- the control unit determines that an ion generation error has occurred and again stops operation when it is detected again that no ions have been generated after a predetermined number of times. A final determination is made by determining whether or not ions have been generated a predetermined number of times or more. Therefore, it is possible to reliably eliminate an erroneous determination that no ions are generated.
- the ion generator is replaceable, and when a new ion generator is installed, the control unit determines the suitability of the ion generator and, in the case of a conforming ion generator, allows the operation of the ion generator. Since the ion generator determined not to generate ions cannot be used, it is replaced with a new ion generator. At this time, if an inferior ion generator is attached, the performance as an ion generator is reduced. In order to prevent this, the control unit allows only compatible ion generators to be used, and in the case of incompatible ion generators, the operation of the ion generator is prohibited so that it cannot be used.
- the generated ions are not caused to flow in the wind, and a high concentration of ions can be detected. Therefore, if ions are generated, the ions can be detected without fail, and it is possible to eliminate erroneous determination that ions are not generated even though ions are generated. Can be enhanced.

Then, ion detection is performed, and whether or not ions are generated is determined in the same manner as described above. If the controller 5 determines in the mode 4 that ions are generated, the controller 5 resets the error counter and executes the normal mode. After the elapse of 3 hours, the control unit 5 performs the determination in the mode 2 again. When the control unit 5 determines in the mode 4 that no ions are generated, the control unit 5 performs the determination in the mode 5 immediately or in a short time.
- the ion determination time is set short, the blower 2 is stopped, the ion generator 1 is turned on for 1 second / off for 1 second, and the ion determination time for 10 seconds. Then, ion detection is performed to determine whether or not ions are generated. If the control unit 5 determines in the mode 5 that ions are generated, the control unit 5 resets the error counter and executes the normal mode.
