Description

  The present invention relates generally to an ion generator, and more particularly to an ion generator that emits ions into the air.

  Conventionally, there are ion generators that release positive ions (plus ions) and / or negative ions (negative ions) into the air. In the ion generator, for example, ions are generated by an ion generator disposed in the middle of the ventilation path inside the ion generator. In a standard ion generator used for an ion generator, a corona discharge is generated by applying a high driving voltage between a needle electrode and a counter electrode or between a discharge electrode and a dielectric electrode. To generate positive ions and / or negative ions. Positive ions and / or negative ions generated by the ion generator are released together with the air passing through the ventilation path into a space outside the ion generator.

  Some positive ions and / or negative ions inactivate suspended particles floating in a space such as a living space or kill suspended bacteria and denature odor components. By releasing such positive ions and / or negative ions into the air, the air can be cleaned. Therefore, such an ion generator that releases positive ions and / or negative ions into the air is used as, for example, an air purifier for purifying the entire air in the living section, an air conditioner, or the like. It is provided in the electrical equipment.

  For example, some commercially available air conditioners equipped with an ion generator display an operating condition of the air conditioner, an ion generation amount, and the like on a display unit of the air conditioner body. In such an air conditioner, the ion generation amount calculated by the control unit is often displayed depending on the operating condition of the air conditioner.

  However, since ions disappear in the air, the ion generation amount calculated by the control unit is different from the ion amount in the space from which the ions are released. Neither positive ions nor negative ions can be seen by human eyes or sensed by human senses. Therefore, even if the display part which displays the generation amount of the ion which the control part of the air conditioner calculated as mentioned above is seen, the user does not know how many ions are actually in the room. In order to know how many ions are in the room, it is necessary to detect the ions in the room.

  For example, in Japanese Patent Application Laid-Open No. 2002-260820 (Patent Document 1), in an ion generation apparatus including a main body having an ion generation function and a remote controller for operating the main body, an ion detector is provided in the remote control. The amount of ions detected by the remote controller is displayed on the display unit of the ion generator main body and the display unit of the remote controller. The user can arbitrarily select the ion measurement location.

  Moreover, in the air conditioner described in Japanese Patent Application Laid-Open No. 10-332164 (Patent Document 2), a radiation electrode for generating ions is provided in a ventilation path from the suction port to the blowout port of the indoor unit, and an ion sensor is provided at the suction port. Is attached. In this air conditioner, the amount of ions is displayed on the display unit based on a signal from the ion sensor. In addition, the control unit of the indoor unit increases the amount of ions generated by the signal received from the ion sensor if the amount of ions in the air is less than the set value, and if the amount of ions in the air is too large, Reduce the amount generated.

  Japanese Patent Laying-Open No. 2005-55028 (Patent Document 3) discloses an air conditioning system including a ceiling-embedded indoor unit, a humidifier, an air cleaner having an ion generator, a humidity sensor, and an ion sensor. Is described. One humidity sensor and one ion sensor are provided on each wall in the room. The air purifier alleviates indoor variations by adjusting the humidification amount and the ion generation amount based on the humidity detected by the humidity sensor and the ion amount detected by the ion sensor.

  However, the number of positive ions and negative ions decreases rapidly as time passes after generation. In particular, when positive ions and negative ions are released into the same space at the same time, the number of ions rapidly decreases due to recombination of positive ions and negative ions. Also, the amount of distribution varies depending on the position in the room, depending on the direction and volume of the wind that sends ions into the ion supply target room. For this reason, in the ion generator described in Japanese Patent Laid-Open No. 2002-260820 (Patent Document 1), for example, even if the amount of ions displayed on the display unit changes, the user with the remote controller has moved. I don't know if the amount of ions in the room has changed.

  Moreover, in the air conditioner described in Japanese Patent Laid-Open No. 10-332164 (Patent Document 2), since the ion sensor is disposed at the suction port of the indoor unit, the amount of ions at a position away from the indoor unit is detected. I can't.

  Moreover, in the air conditioning system described in Japanese Patent Application Laid-Open No. 2005-55028 (Patent Document 3), each of the ion sensor and the humidity sensor is installed on each wall surface in the room, and humidification is performed based on the detection results of these sensors. As described above, the ion concentration distribution is more likely to change with time than the humidity distribution, and the difference depending on the position is also large. Therefore, even if an ion sensor is attached to each wall surface and the amount of ions generated is adjusted based on the amount of ions detected by each ion sensor, the concentration of ions in the entire room cannot be adjusted appropriately.

  If the concentration of positive ions and / or negative ions is not maintained at a constant ion concentration, the original air cleaning effect by ions, that is, effects such as sterilization, sterilization, and deodorization may not be obtained. In order to clean the inside of the ion supply target chamber by positive ions and / or negative ions, the positive ions and / or negative ions are supplied so as to have a preferable concentration distribution in a wide range within the ion supply target space. There is a need.

In this way, by rotating the ion generator main body 100, the direction in which ions are released from the ion emission port (FIGS. 2 and 3) to the outside of the ion generator main body 100 can be changed.

  As the angle detector 84 of the turntable 80, a multipoint switch, a trimmer, a magnet switch, or the like can be used. Further, it is possible that the turntable drive unit 83 also serves as the angle detector 84 by using the turntable drive unit 83 as a stepping motor.

Based on the signal received from the operation switch 101, the control unit 110 causes the positive ion generation unit 61 and the negative ion generation unit 62 to generate positive ions and negative ions and to stop the generation of ions. Send a control signal. Moreover, the control part 110 transmits a control signal to the motor 2, and changes ventilation volume. Further, the control unit 110 transmits a control signal to the display unit 102 so as to display the generation status of positive ions and negative ions.

  The ion amount detectors 91, 92, 93, 94 detect positive ions and negative ions released into the air from the ion generator main body 100 (FIG. 2, FIG. 3), and transmit signals to the control unit 110. . Signal transmission from the ion amount detectors 91, 92, 93, 94 to the control unit 110 is performed by, for example, infrared communication.

As will be described later, the control unit 110 controls the positive ion generation unit 61, the negative ion generation unit 62, the motor 2, and the turntable drive unit 83 based on signals received from the ion amount detectors 91, 92, 93, 94. To do. The control unit 110 also displays the amount of positive ions and negative ions detected by the ion amount detectors 91, 92, 93, 94 based on the signals received from the ion amount detectors 91, 92, 93, 94. Thus, a control signal is transmitted to the display unit 102.

  Further, the control unit 110 transmits a signal to the ion amount detectors 91, 92, 93, 94, and the ion amount detected by the ion amount detectors 91, 92, 93, 94 and a predetermined predetermined amount. The difference from the ion amount can be set to be transmitted to the control unit.

  The ion amount detectors 91, 92, 93, 94 may be configured to transmit and receive signals to each other.

  The angle detector 84 detects the angle at which the turntable 80 (FIG. 6) is rotated by the turntable drive unit 83 and transmits a signal to the control unit 110.

  An example of the operation of the ion generator configured as described above will be described with reference to FIGS. In the flowchart shown in FIG. 8, the subject of the predetermined determination is the control unit 110.

  When the operation switch 101 is operated by the user and the operation of the ion generator is started, the positive ion generator 61, the negative ion generator 62, and the motor 2 of the blower are driven.

  When the positive ion generator 61 and the negative ion generator 62 are driven, positive ions and negative ions are generated in the ion generators 6a, 6b, 6c, and 6d, respectively.

  When the motor 2 is driven, the impellers 3 and 3 rotate, and indoor air is sucked into the two casings 4 and 4 from the two suction ports 11 and 11. Foreign matter such as dust in the sucked air is removed by the filters 8 and 8. The air sucked into the casings 4 and 4 becomes a laminar flow by the arc-shaped guide walls 41 and 41 around the impellers 3 and 3. The laminar air flows along the arcuate guide walls 41 and 41 to the air outlets 42 and 42, and is blown out from the air outlets 42 and 42 into the ducts 5 and 5.

  In the duct 5, positive ions and negative ions are contained in the air passing through the ion generators 6a, 6b, 6c, and 6d. Air containing positive ions and negative ions is discharged from the ion discharge port 73 to the outside of the ion generator main body 100 and supplied into the ion supply target chamber 200.

  In step S001, positive ions and negative ions supplied into the ion supply target chamber 200 are detected by the ion amount detectors 91, 92, 93, 94. In step S002, control unit 110 determines whether or not a predetermined time has elapsed from the start of operation of the ion generator. If the predetermined time has not elapsed since the start of the operation of the ion generator, the process returns to step S002. If a predetermined time has elapsed from the start of operation of the ion generator, the process proceeds to step S003.

  In step S003, the control unit 110 controls the turntable drive unit 83 so that the table 81 of the turntable 80 is rotated by a predetermined angle. When the turntable drive unit 83 is rotated, the specific ion amount detector of the ion amount detectors 91, 92, 93, and 94 and the control unit 110 perform infrared communication according to the angle of rotation. In step S004, the control unit 110 receives a signal when the ion amount detectors 91, 92, 93, 94 and the control unit 110 perform infrared communication. The control unit 110 stores the angle detected by the angle detector 84 at that time each time infrared communication is performed with one of the ion amount detectors 91, 92, 93, 94. In this way, in the subsequent process, the control unit 110 identifies the ion amount detectors 91, 92, 93, and 94 by angles detected by the angle detector 84 when infrared communication is performed. can do.

  In step S005, the control unit 110 detects the amount of ions detected among the ion amount detectors 91, 92, 93, and 94 as a predetermined ion amount that is smaller than the first set value. Determine if there is a quantity detector. If there is an ion amount detector whose detected ion amount is smaller than the first set value, the process proceeds to step S006. If there is no ion amount detector whose detected ion amount is smaller than the first set value, the process proceeds to step S007.

  In step S006, the control unit 110 controls the turntable drive unit 83 so that the ion emission port 73 is directed toward the ion amount detector whose detected ion amount is smaller than the first set value. The control unit 110 stops the rotation of the turntable 80 for a predetermined time, and continues to release ions in the direction of the ion amount detector whose detected ion amount is smaller than the first set value. At this time, the control unit 110 may control the motor 2 so as to increase the amount of air sent from the ion emission port 73. After a predetermined time has passed, the process returns to step S005.

  The ion generator repeats step S005 and step S006 until there is no ion amount detector whose detected ion amount is smaller than the first set value. By doing so, in the ion supply target chamber 200, the ion amount is made larger than the first set value at any position where the ion amount detectors 91, 92, 93, 94 are arranged. be able to.

  In step S007, the control unit 110 determines that the amount of ions detected among the ion amount detectors 91, 92, 93, and 94 is larger than the second set value as the predetermined amount of ions determined in advance. Determine if there is a quantity detector. If there is an ion amount detector whose detected ion amount is larger than the second set value, the process proceeds to step S008. If there is no ion amount detector whose detected ion amount is larger than the second set value, the process returns to step S003. The second set value is a value larger than the first set value.

  In step S008, the control unit 110 controls the turntable drive unit 83 and the motor 2 so as to reduce the amount of air blown in the direction of the ion amount detector in which the detected ion amount is larger than the second set value. . For example, the control unit 110 drives the turntable driving unit 83 to prevent the ions in the ion generator main body 100 from being blown in the direction of the ion amount detector whose detected ion amount is larger than the second set value. The direction of the discharge port 73 is changed. For example, the control unit 110 controls the motor 2 to reduce the amount of air blown toward the ion amount detector in which the detected ion amount is larger than the second set value. Thereafter, the process returns to step S005.

  The ion generator has no ion amount detector in which the amount of detected ions is smaller than the first set value, and there are no ion amount detectors in which the amount of detected ions is larger than the second set value. Steps S005 to S008 are repeated. In this way, in the ion supply target chamber 200, the ion amount is larger than the first set value at any position where the ion amount detectors 91, 92, 93, 94 are arranged, It can be within a range smaller than the second set value.

  In this embodiment, the control unit 110 is configured such that the ion generator main body 100 is rotated by the turntable 80 so that the specific ion amount detectors 91, 92, 93, and 94 are at a specific rotation angle. Signals are transmitted and received by performing infrared communication. However, the ion amount detectors 91, 92, 93, 94 and the control unit 110 may transmit and receive signals by other methods. For example, the data transmission / reception system for the ion amount may be a specific low-power radio system. When data is transmitted between the ion quantity detectors 91, 92, 93, 94 and the control unit 110 by radio waves such as specific low-power radio, the installation location of the ion quantity detectors 91, 92, 93, 94 It is necessary to specify. Therefore, in this case, it is necessary to have a device configuration capable of transmitting the data on the installation locations of the ion amount detectors 91, 92, 93, and 94 simultaneously with the data on the ion amount. For example, it is conceivable that a small GPS is mounted on the ion amount detectors 91, 92, 93, 94. When ion quantity detectors 91, 92, 93, 94 equipped with a small GPS are used, the ion quantity detectors 91, 92, 93, 94 are divided into a plurality of angles in the left-right direction around the ion generator main body 100. To do. The ion amount detectors 91, 92, 93, 94 are arranged like the “right 1”, “right 2”, “left 1”, “left 2”, etc. This direction is transmitted to the controller 110 of the ion generator main body 100 together with the amount of ions detected by the ion amount detectors 91, 92, 93, 94.

  In this embodiment, the communication performed between the ion quantity detectors 91, 92, 93, 94 and the control unit 110 is wireless communication, but may be wired communication.

  Further, the ion amount detectors 91, 92, 93, 94 may be configured to transmit information on the ion amount to the control unit 110 at predetermined time intervals.

  Further, in this embodiment, the turntable 80 is rotated to change the direction of the ion emission port 73, or the motor 2 is controlled to change the amount of air blown to release the ion emission port. The amount of positive ions and negative ions is adjusted. However, in the ion generator, the amount of positive ions and negative ions generated may be adjusted by controlling the positive ion generator 61 and the negative ion generator 62. As a method of increasing the amount of ions generated in the positive ion generator 61 and the negative ion generator 62, the discharge voltage of the ion generators 6a, 6b, 6c, 6d is increased, or the ion generators 6a, 6b, 6c, There is a method of increasing the applied pulse of 6d or increasing the air flow rate to the ion generators 6a, 6b, 6c, 6d, that is, increasing the air flow rate to the ion generators 6a, 6b, 6c, 6d. is there. On the other hand, in order to reduce the amount of ions generated in the positive ion generator 61 and the negative ion generator 62, the discharge voltage of the ion generators 6a, 6b, 6c, 6d is decreased or the ion generators 6a, 6b, 6c, 6d applied pulses are decreased, or the amount of air blown to the ion generators 6a, 6b, 6c, 6d is decreased, that is, the air blowing speed to the ion generators 6a, 6b, 6c, 6d is decreased. It is common.

  Also, in step S006 of the flowchart shown in FIG. 8, the amount of ions released in the direction of the ion amount detector whose detected ion amount is smaller than the first set value is increased. However, in order to simplify the ion generation device, in step S006, the ion generation device is used until the ion amounts detected by all the ion amount detectors 91, 92, 93, 94 become larger than the first set value. The turntable 80 may continue to rotate clockwise and counterclockwise while discharging ions from the main body 100.

  In this embodiment, the concentration of ions detected in the ion supply target chamber 200 is controlled to be in a range between the first set value and the second set value. However, for example, the control unit 110 detects that the air containing ions is in the direction of the ion quantity detector that indicates the minimum ion quantity among the ion quantities detected by the ion quantity detectors 91, 92, 93, and 94. You may drive the motor 2 and the turntable drive part 83 so that it may blow. Moreover, you may drive the motor 2 and the turntable drive part 83 so that the air containing an ion may be sent in the direction of the ion amount detector which detected the least ion amount.

  Furthermore, in the embodiment of the present invention, the setting values of the ion amount detectors 91, 92, 93, 94 are two, but a plurality of values may be set. Further, from the ion amount detectors 91, 92, 93, 94, the deviation value information with respect to the set value and the result of the determination whether it is simply greater than the set value or less than the set value are transmitted to the control unit 110. May be. In this embodiment, the first set value is described as the lower limit value of the ion amount, and the second set value is set as the upper limit value of the ion amount. However, the ion amount detectors 91, 92, 93, and 94 are independent of the set value. It is also possible to transmit the value detected in step 1 as data and manage the distribution of the ion amount as an absolute value.

  Further, it is possible to transmit signals from the ion amount detectors 91, 92, 93, 94 only when an “event” occurs. As a method of transmitting a signal only when an “event” occurs, for example, there is a method of transmitting information to the control unit 110 only when the amount of ions deviates from an upper limit or a lower limit of a set value. By doing so, it is possible to prevent the battery used as a power source for the remote control from being normally consumed, and to enable long-term use of the battery.
