  The present invention relates to an ion generator that sends out ions generated in an ion generator to the outside of the apparatus.

An ion generator is comprised as an air cleaner installed indoors, for example. Such an ion generator sends out the ion which generate | occur | produced in the ion generating part to the apparatus exterior with the air which a ventilation part blows (refer patent document 1).
The delivered ions kill or inactivate fungi, viruses, allergens, and the like. For this reason, when such an ion generator is used in a bedroom, for example, while the user is asleep, the morbidity of a cold can be suppressed, or the symptoms of hay fever can be alleviated.

Under circumstances where quietness is important, such as during a user's sleep, it is considered to use a table lamp that includes an ion generation unit and an illumination unit without providing an air blowing unit that generates an operating sound and a blowing sound. (See Patent Document 2). For example, when this desk lamp is arranged at the bedside of the user, ions can be suspended at the bedside of the user by natural air convection in the room.
By the way, the air conditioner which performs air-conditioning control according to a user's sleep state is proposed (refer patent document 3). This air conditioner adjusts the air conditioning temperature according to the depth of sleep obtained based on the user's movement and the surface temperature.

Japanese Patent No. 3770784 Utility Model Registration No. 3075355 JP 2010-136992 A

The desk lamp described in Patent Document 2 does not include a blower. For this reason, the range in which the ions generated in the ion generation unit float densely is limited to a narrow range around the desk lamp.
On the other hand, when using an ion generator provided with an air blower, the ion concentration around the user can be efficiently increased by blowing air containing ions toward the user.
However, for example, when the direction or posture of the ion generating device is changed by touching the ion generating device with the limb of the user who has turned over, the air containing the ions is blown out in a direction where the user does not exist. In this case, the ion concentration around the user cannot be increased efficiently.

If the air volume of the air blower is increased, ions can be suspended in the entire bedroom. For this reason, the ion concentration around the user can be efficiently increased regardless of where the user is in the bedroom.
However, if the air flow rate is increased, the operating sound and the air blowing sound of the air blowing unit also increase in volume and become noise, which may disturb the user's sleep.
By the way, when the illumination unit is provided like the desk lamp described in Patent Document 2, if the illumination unit is controlled according to the state of the user like the air conditioner described in Patent Document 3, the convenience for the user is further improved. To do.

The present invention has been made in view of such circumstances, the primary object is to provide an ion generating apparatus can be enhanced efficiently ion concentration near the user in response to User chromatography THE.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.

Embodiment 1.
FIG. 1 is a side view showing an external configuration of an ion generator 1 according to Embodiment 1 of the present invention, and also illustrates a use state of the ion generator 1. Hereinafter, the vertical direction in the figure is referred to as the vertical direction of the ion generator 1.
The ion generator 1 in the present embodiment is in the form of a desk lamp that includes an apparatus main body 10, an arm portion 11, and a support base 12. Such an ion generator 1 is installed in the bedside of the user 2 who lies in the bedroom. In addition, the ion generator 1 may be installed on a desk or a bedside. Further, the user 2 is not limited to a human being, and may be a pet such as a dog or a cat.

In the apparatus main body 10, functional units of the ion generator 1 such as an ion generation unit 108, a blower unit 110, and an illumination unit 13 described later are gathered in a compact manner.
The arm unit 11 connects the apparatus main body 10 and the support base 12. Further, the arm portion 11 is configured to be deformable so as to be able to be bent and to maintain the deformed state. For this reason, the user 2 can change the position and posture of the apparatus main body 10 by deforming the arm portion 11.
The support base 12 has a size and weight capable of supporting the apparatus main body 10 and the arm portion 11 so that the entire apparatus does not fall down regardless of the position and posture of the apparatus main body 10, and is on the floor surface of the bedside. Placed.

Here, the predetermined range in the present embodiment is a range of 50 cm from the apparatus main body 10 on the front side of the apparatus main body 10. The user 2 changes the position and posture of the apparatus main body 10 or changes his / her position and posture so as to adjust his / her head to lie within a predetermined range.
FIG. 2 is a front view illustrating an external configuration of the apparatus main body 10 included in the ion generating apparatus 1, and FIG. 3 is a side sectional view illustrating an internal configuration of the apparatus main body 10.
FIG. 4 is a perspective view showing an external configuration of the ion generator 108 provided in the ion generator 1.
FIG. 5 is a block diagram showing the configuration of the control system of the ion generator 1.

FIG. 6 is a circuit diagram illustrating the configuration of the ion generation unit 108 and the ion generation amount adjustment unit 115 included in the ion generation apparatus 1.
As shown in FIGS. 2 and 3, the casing 101 forming the appearance of the apparatus main body 10 is roughly divided into three parts.
The first part is a disk-shaped part (hereinafter referred to as a fan housing) in which a fan 110b described later is accommodated. One end surface side / the other end surface side (left side / right side in FIG. 3) of the fan housing is the front side / back side of the ion generator 1.
The second part is a cylindrical part (hereinafter referred to as a motor casing) that is concentrically located on the back side of the fan casing and accommodates a fan motor 110a described later.

The third part is an inverted frustum-shaped part (hereinafter referred to as a sensor casing) that is located immediately below the fan casing and in which each of the infrared sensor 103 and the distance measuring sensor 104 described later is arranged. The lower part of the sensor casing is connected to the upper end of the arm part 11.
A suction port 111 for sucking air into the motor housing is formed on the rear surface side of the motor housing of the housing 101. A filter 109 is disposed in the suction port 111. The filter 109 filters and cleans the air passing through the suction port 111.

Further, an air outlet 102 for blowing air from the inside of the fan housing is formed on the front side of the fan housing of the housing 101. A lattice 107 is disposed at the outlet 102. The lattice 107 rectifies the air passing through the air outlet 102 and prevents foreign matter (for example, the finger of the user 2) from entering the inside of the housing 101.
Furthermore, an opening 114 is formed at the boundary between the fan housing and the motor housing of the housing 101 so as to communicate the inside of both.
The inside of the housing 101 that connects the suction port 111, the opening 114, and the air outlet 102 functions as a blower passage 113 through which air flows.
A blower unit 110 is disposed in the middle of the air passage 113.

3 and 5 includes an electric fan motor 110a and a fan 110b that rotates when the fan motor 110a operates. As fan 110b rotates, air flows from suction port 111 to opening 102 through opening 114.
The air blowing amount of the air blowing unit 110 is configured to be changeable in two stages of air blowing amounts Wa and Wb (0 <Wa <Wb). When the air blowing unit 110 is blowing air with the air volume Wa, the operation sound and the air blowing sound of the air blowing unit 110 are smaller than when the air blowing unit 110 is blowing air with the air volume Wb. Moreover, when the ventilation part 110 is blowing with the ventilation volume Wa, the electric power consumed by the ventilation part 110 is smaller than the case where the ventilation part 110 is blowing with the ventilation volume Wb.

The increase / decrease in the amount of air blown in the blower unit 110 is realized by increasing / decreasing the number of rotations of the fan motor 110a. For this purpose, the air blower 110 may be configured to change the output of the fan motor 110a by switching, for example, a plurality of tap terminals provided in the motor winding of the fan motor 110a. Or the motor drive of the fan motor 110a should just be the structure which changes the voltage waveform or electric current waveform applied to the fan motor 110a by being controlled by the control part 112 mentioned later.
Note that the amount of air blown by the blower 110 may be changeable in three or more stages.
The motor housing of the housing 101 accommodates the ion generation unit 108 such that ion generation electrodes 108 a and 108 c described later face the air passage 113.

3 to 6 includes needle-like ion generation electrodes 108a and 108c and counter electrodes 108b and 108d arranged to face the ion generation electrodes 108a and 108c. When a high voltage is applied between the ion generating electrode 108a and the counter electrode 108b (or between the ion generating electrode 108c and the counter electrode 108d), positive ions (or negative ions) are generated by corona discharge. The positive ions and negative ions generated at this time are H ^+. (H ₂ O) _m (m is a natural number) and O ₂ ⁻ (H ₂ O) _n (n is a natural number). The generated positive ions and negative ions (hereinafter referred to as positive and negative ions) float in the air passage 113.

Positive and negative ions floating in the air passage 113 are sent out from the blower outlet 102 to the outside of the apparatus together with the air flowing through the air passage 113 when the air blowing unit 110 blows air.
More specifically, when the air blowing unit 110 is blowing air with an air volume Wa, positive and negative ions are gently and directly sent into a predetermined range, and the natural convection of air mainly outside the predetermined range. Is slowly dissipated.
On the other hand, when the air blowing unit 110 is blowing air with the air volume Wb, positive and negative ions are sent out rapidly and directly into a predetermined range, and out of the predetermined range mainly by forced circulation of air, Dissipates rapidly.

The ion generation unit 108 is not limited to the configuration including the ion generation electrodes 108a and 108c and the counter electrodes 108b and 108d. For example, the ion generation unit 108 may include an electrode printed on a substrate or a metal electrode wound around a cylinder. The ion generator 108 is not limited to a configuration that generates positive and negative ions, and may be configured to generate only one of positive and negative ions.
The positive and negative ions described above are sterilized or inactivated by causing a chemical reaction by attaching to airborne bacteria or viruses.
The ion generation amount adjustment unit 115 shown in FIGS. 5 and 6 uses a switching circuit interposed between the ion generation unit 108 and the control unit 112, and is controlled by the control unit 112, whereby the ion generation unit 108 is controlled. Adjust the amount of ions generated.

More specifically, the ion generation amount adjustment unit 115 changes the frequency of the pulse signal to be applied to the ion generation unit 108 without changing the voltage value to be applied to the ion generation unit 108, thereby changing the ion generation unit 108. Increase or decrease the amount of ions generated. The part of the control unit 112 that controls the ion generation amount adjustment unit 115 is an ion generation amount control unit, and the ion generation amount control unit of the control unit 112 changes / maintains the frequency by the ion generation amount adjustment unit 115. To control.
In the present embodiment, the ion generation amount of the ion generation unit 108 is configured to be changeable in two stages of ion generation amounts Na and Nb (0 <Na <Nb). When the ion generation amount of the ion generation unit 108 is the ion generation amount Na, the power consumed by the ion generation unit 108 is smaller than that when the ion generation unit 108 is the ion generation amount Nb.

It should be noted that the ion generation amount of the ion generation unit 108 may be changed in three or more stages.
The illumination part 13 shown in FIG.2, FIG3 and FIG.5 consists of LED, and illuminates the predetermined range. The brightness of the illumination unit 13 is configured to be changeable in two stages of illuminances La and Lb (0 <La <Lb) within a predetermined range. When the brightness of the illumination unit 13 is the illuminance La, the power consumed by the illumination unit 13 is smaller than when the illumination unit 13 is the illuminance Lb.
Note that the brightness of the illumination unit 13 may be changeable in three or more stages.

The intensity of the brightness in the illumination unit 13 is, for example, by changing the current waveform to be applied to the LEDs constituting the illumination unit 13, or by providing a plurality of LEDs and increasing or decreasing the number of LEDs to be lit. Can be switched.
Such an illumination unit 13 is disposed on the front side of the sensor casing of the casing 101. The illumination unit 13 with illuminance La is used as a reading lamp at night, for example, and the illumination unit 13 with illuminance Lb is used as a local illumination lamp at night, for example.
An infrared sensor 103 and a distance measuring sensor 104 are also arranged on the front side of the sensor casing of the casing 101.

  The distance measuring sensor 104 shown in FIGS. 2 and 5 is for determining whether or not an object exists within a predetermined range, and the infrared sensor 103 is used to determine whether or not the object existing within the predetermined range is a human being. This is to determine whether or not.

  More specifically, the distance measuring sensor 104 detects a distance to an object located on the front side of the apparatus main body 10. In the present embodiment, when the detected distance is 50 cm or less (or exceeding), the object is located within a predetermined range (or outside the predetermined range). That is, an object exists (or does not exist) within a predetermined range. When positive and negative ions are sent out as described above, the sent positive and negative ions rapidly disappear and decrease with distance, so the range in which positive and negative ions maintain a preferred concentration is set as a predetermined range. Obviously, the predetermined range is enlarged when the ion concentration generated by the ion generator 108 is high, and the predetermined range is reduced when the ion concentration is low. For this purpose, the predetermined range is determined in advance by measurement. When only positive ions or negative ions are sent out, the concentration of the sent ions is reduced by diffusion, so the range in which positive or negative ions maintain a preferred concentration is set as a predetermined range. In the case of illumination or the like, a range in which preferable illuminance is maintained is a predetermined range.

The infrared sensor 103 detects the surface temperature of the object. Usually, the temperature of non-human articles and air existing indoors is much lower than the human surface temperature (about 34 ° C.). For this reason, a predetermined temperature in consideration of the human surface temperature is set in the control unit 112 in advance. When the detection result of the infrared sensor 103 is equal to or higher than (or lower than) a predetermined temperature, the object is a human (or not a human).
The infrared sensor 103 and the distance measuring sensor 104 function as a living body detection unit in the embodiment of the present invention. This living body detection unit always detects the presence or absence of the user 2. Therefore, even if the user 2 repeatedly enters and leaves the predetermined range, there is no particular problem.

An operation SW (switch) 105 and a timer SW 106 are arranged on the side surface side of the sensor housing of the housing 101.
The ion generator 1 of this Embodiment has two types of operation modes, an ion mode and LED mode.
In the ion mode, the ion generation unit 108 and the air blowing unit 110 operate, and the illumination unit 13 does not operate. In the LED mode, the ion generating unit 108, the air blowing unit 110, and the lighting unit 13 are activated. In any mode, the infrared sensor 103, the distance measuring sensor 104, the notification unit 14 described later, and the like operate.

The operation SW 105 shown in FIGS. 2 and 5 is for switching the operation of the ion generator 1 in the ion mode, the operation in the LED mode, and the operation stop. For this reason, the operation SW 105 is configured to be slidable to three positions corresponding to operation and operation stop in each mode. Hereinafter, these three positions are referred to as an ion position, an LED position, and a stop position, and the stop position is located between the ion position and the LED position. Note that the three positions may be arranged in the order of the stop position, the ion position, and the LED position.
Note that each time the user 2 operates the operation SW 105, the operation and the operation stop in each mode may be switched in order.

  The timer SW 106 is for switching start / stop of timer operation for stopping the operation of the ion generator 1 after a predetermined elapsed time. In the LED mode, when the user 2 operates the timer SW 106 when the timer is not operated, the timer operation is started. If the user 2 operates the timer SW 106 during the timer operation, the timer operation is stopped. For example, the user 2 operates the timer SW 106 before going to bed, thereby causing the ion generator 1 to perform a timer operation.

The predetermined elapsed time related to the timer operation is set in the control unit 112 when the user 2 operates the setting unit 15 shown in FIG. Hereinafter, the predetermined elapsed time related to the timer operation is referred to as a set time. For example, the default setting time may be set in the control unit 112 at the time of factory shipment. The setting unit 15 uses, for example, a rotary knob provided on the upper surface side of the support base 12.
The notification unit 14 illustrated in FIG. 5 includes, for example, an LED, and notifies the user 2 of the operation mode of the ion generator 1 and whether or not the timer operation is performed by lighting / flashing or a lighting color. The non-lighting of the notification unit 14 means that the ion generator 1 is not operating. Such a notification unit 14 is provided on the back side of the apparatus main body 10 or the upper surface side of the support base 12.

  Positive and negative ions are not visible, and when the air blowing unit 110 is blowing air with an air volume Wa, the operating sound and the air blowing sound of the air blowing unit 110 are small. Therefore, if the notification unit 14 is not provided, in order for the user 2 to know whether the ion generator 1 is operating or in which mode it is operating, which operation SW 105 is There is no choice but to check whether it is in the position. On the other hand, the user 2 does not know whether or not the timer is operated even if the timer SW 106 is examined. That is, the alerting | reporting part 14 has improved the convenience of the user 2 at the time of knowing the driving | running state of the ion generator 1. FIG.

The control unit 112 shown in FIGS. 3 and 5 is a control center of the ion generator 1. The control unit 112 is accommodated in the sensor casing of the casing 101, and counts elapsed time, for example, by counting clocks.
Moreover, the control part 112 adjusts the ventilation volume of the ventilation part 110 according to the presence or absence of the user 2 within the predetermined range. Furthermore, the control part 112 adjusts the brightness of the illumination part 13 according to the presence or absence of the user 2 within a predetermined range. Note that either one of the air volume of the air blowing unit 110 and the brightness of the illumination unit 13 may be always constant regardless of the presence or absence of the user 2 within a predetermined range.

Furthermore, the ion generation amount adjustment unit 115 controlled by the ion generation amount control unit of the control unit 112 adjusts the ion generation amount of the ion generation unit 108 according to the presence or absence of the user 2 within a predetermined range. Note that the ion generation amount of the ion generation unit 108 may be always constant regardless of the presence or absence of the user 2 within a predetermined range. In this case, the ion generator 1 does not need to include the ion generation amount adjustment unit 115.
7 to 10 are flowcharts showing the procedure of the ion generation process executed by the ion generator 1. Before the execution of the ion generation process is started, the operation SW 105 is arranged at the stop position.

As shown in FIG. 7, the control unit 112 first sets the timer flag indicating that the ion generator 1 is in a timer operation to a reset state (S11). The reset timer flag indicates that the ion generator 1 is not operating as a timer.
Next, the control unit 112 determines whether or not the operation SW 105 has been operated and arranged at the ion position (S12).
When the operation SW 105 is arranged at the ion position (YES in S12), the control unit 112 operates the air blowing unit 110 with the air blowing amount Wa (S13), and operates the ion generating unit 108 with the ion generation amount Na (S14). Then, required parts of the apparatus excluding the illumination unit 13 such as the notification unit 14 and the various sensors 103 and 104 are operated (S15).

After the process of S15 is completed, the control unit 112 determines whether or not an object exists within a predetermined range based on the detection result of the distance measuring sensor 104 (S16).
When an object exists within the predetermined range (YES in S16), the control unit 112 determines whether the object existing within the predetermined range is a human based on the detection result of the infrared sensor 103 (S17). .

  When the object existing within the predetermined range is a human (YES in S17), the control unit 112 maintains the air volume of the air blowing unit 110 with the air volume Wa or changes the air volume Wb to the air volume Wa. (S18). Further, the ion generation amount control unit of the control unit 112 maintains the ion generation amount of the ion generation unit 108 at the ion generation amount Na or changes the ion generation amount Nb from the ion generation amount Nb to the ion generation amount Na. Is controlled (S19).

  The case of YES in S17 is a case where the user 2 is within a predetermined range. At this time, a gentle wind containing a small amount of positive and negative ions is blown onto the head of the user 2 by executing the processes of S18 and S19. Moreover, the ion generator 1 has high silence. Therefore, the ion concentration around the user 2 existing within the predetermined range can be efficiently increased. Moreover, the blowing wind and the noise generated by the ion generator 1 do not disturb the rest or sleep of the user 2. Furthermore, since the power consumption of the ion generator 1 is reduced, it can contribute to energy saving.

  When the object does not exist within the predetermined range (NO in S16), or when the object that exists within the predetermined range is not a human (NO in S17), the control unit 112 sets the blowing amount of the blowing unit 110 to the blowing amount Wa. Is changed to the air flow rate Wb or maintained at the air flow rate Wb (S20). Further, the ion generation amount control unit of the control unit 112 changes the ion generation amount of the ion generation unit 108 from the ion generation amount Na to the ion generation amount Nb or maintains the ion generation amount Nb so as to maintain the ion generation amount Nb. Is controlled (S21).

  The case of NO in S16 or S17 is a case where the user 2 does not exist within a predetermined range. At this time, by executing the processing of S20 and S21, after a wind containing a large amount of positive and negative ions blows out to a place where no one is present, the entire room is forcibly circulated. As a result, the ion concentration around the user 2 that may exist outside the predetermined range can be efficiently increased. Moreover, strong wind is not directly blown to the user 2. Moreover, since it is thought that the user 2 is not resting or sleeping, even if the ion generator 1 emits a little noise, it does not become a big problem.

By the way, even when the orientation or posture of the apparatus main body 10 is changed by touching the ion generating apparatus 1 with the limb of the user 2 who has turned over, NO is determined in S16 or S17, and the processes of S20 and S21 are executed. Is done.
In the previous process, both S16 and S17 were YES, but in this process, if S16 or S17 is NO, the ion generator 1 blinks the illumination unit 13 or sounds from a speaker (not shown). An alarm may be issued to the user by output or the like. This is because the user does not exist within the predetermined range at the time of the previous determination, but the user does not exist within the predetermined range at the time of the current determination. This is a configuration that warns that the orientation or posture has changed.

The control part 112 which performs the process of S18 and the process of S20 functions as an air volume adjustment part in the embodiment of the present invention.
When the ion generation amount control unit of the control unit 112 executes the process of S19 and the process of S21, the ion generation amount adjustment unit 115 functions as the ion generation amount adjustment unit in the embodiment of the present invention.
After the process of S19 or S21 is completed, the control unit 112 determines whether or not the operation SW 105 is operated and placed in the stop position (S22).

When the operation SW 105 is arranged at the stop position (YES in S22), the control unit 112 stops the operation of the ion generating device 1 by stopping all the operating units such as the ion generating unit 108 and the air blowing unit 110. It stops (S23) and ends the ion generation process.
When the operation SW 105 is not arranged at the stop position (NO in S22), that is, when the operation SW 105 is still arranged at the ion position, the control unit 112 sets the timer flag as shown in FIG. It is determined whether or not (S31).

If the timer flag has been reset (NO in S31), the control unit 112 determines whether or not the timer SW 106 has been operated (S32), and if it has been operated (YES in S32), sets the timer flag ( S33), the time elapsed since the timer SW 106 was operated is started (S34). After the process of S34 is completed or when the timer SW 106 is not operated (NO in S32), the control unit 112 returns the process to S16.
When the timer flag is set (YES in S31), the control unit 112 determines whether or not the elapsed time during counting is equal to or longer than the set time for timer operation (S35).

When the elapsed time is equal to or longer than the set time (YES in S35), the control unit 112 finishes counting the elapsed time (S36) and resets the timer flag (S37). Next, the control unit 112 moves the process to S23.
When the elapsed time is less than the set time (NO in S35), the control unit 112 determines whether or not the timer SW 106 has been operated (S38).
When the timer SW 106 is operated (YES in S38), the control unit 112 executes the processes of S39 and S40 as in S36 and S37, and then returns the process to S16. When the timer SW 106 is not operated (NO in S38), the control unit 112 returns the process to S16 without executing the processes of S39 and S40.

When the operation SW 105 is not arranged in the ion position (NO in S12), the control unit 112 determines whether or not the operation SW 105 is operated and arranged in the LED position as shown in FIG. 9 (S51).
When the operation SW 105 is arranged at the LED position (YES in S51), the control unit 112 operates the blowing unit 110 with the blowing amount Wa (S52) and operates the ion generating unit 108 with the ion generation amount Na (S53). Then, the illumination unit 13 is operated with the illuminance La (S54), and required units such as the notification unit 14 and the various sensors 103 and 104 are operated (S55).

After the process of S55 is completed, the control unit 112 executes the process of S56 as in S16. If an object exists within the predetermined range (YES in S56), the control unit 112 executes the process of S57 as in S17.
When the object existing within the predetermined range is a human (YES in S57), the control unit 112 executes the processing of S58 and S59 in the same manner as the processing of S18 and S19, and the brightness of the illumination unit 13 is set to the illuminance. It maintains at La or changes from illuminance Lb to illuminance La (S60).

In the case of YES in S57, the same effect as in the case of YES in S17 described above can be obtained. Furthermore, the reading light can be provided to the user 2 existing within the predetermined range by executing the process of S60.
When the object does not exist within the predetermined range (NO in S56), or when the object that exists within the predetermined range is not a human (NO in S57), the control unit 112 performs S61 and S61 similarly to the processes of S20 and S21. The process of S62 is executed, and the brightness of the illumination unit 13 is changed from the illuminance La to the illuminance Lb or maintained at the illuminance Lb (S63).

In the case of NO in S56 or S57, the same effect as in the case of NO in S16 or S17 described above can be obtained. Furthermore, the room can be illuminated by executing the process of S63. For this reason, the field of view of the user 2 that may exist outside the predetermined range can be brightened.
By the way, even when the orientation or posture of the apparatus main body 10 is changed by touching the ion generating device 1 with the limb of the user 2 who has turned over, NO is determined in S56 or S57, and the process of S63 is executed. . At this time, the ion generator 1 not only emits noise, but also turns on the illumination unit 13 with illuminance Lb.

The control unit 112 that executes the processes of S58 and S60 and the processes of S61 and S63 functions as an air volume adjustment unit and an illumination adjustment unit in the embodiment of the present invention.
When the ion generation amount control unit of the control unit 112 executes the process of S59 and the process of S62, the ion generation amount adjustment unit 115 functions as the ion generation amount adjustment unit in the embodiment of the present invention.
After the process of S60 or S63 is completed, the control unit 112 executes the process of S64 similarly to the process of S22.

When the operation SW 105 is arranged at the stop position (YES in S64), the control unit 112 stops all of the operating units such as the ion generation unit 108, the air blowing unit 110, and the illumination unit 13 to stop ions. The operation of the generator 1 is stopped (S65), and the ion generation process is terminated.
When the operation SW 105 is not arranged at the stop position (NO in S64), that is, when the operation SW 105 is kept arranged at the LED position, the control unit 112 performs the process of S71 as in S31 as shown in FIG. Execute.
The processing of S71 to S80 is the same as the processing of S31 to S40.

However, after the process of S74 is completed or when the timer SW 106 is not operated (NO in S72), the control unit 112 returns the process to S56. In addition, after the process of S77 ends, the control unit 112 moves the process to S65. Furthermore, after the process of S80 ends or when the timer SW 106 is not operated (NO in S78), the control unit 112 returns the process to S56.
As shown in FIG. 9, when the operation SW 105 is not arranged at the LED position (NO in S51), that is, when the operation SW 105 remains arranged at the stop position, the control unit 112 returns the process to S11. .

  Note that S16 or S56 executed immediately after the operation SW 105 is placed at the ion position or the LED position may be executed after a predetermined time has elapsed since the operation SW 105 was operated (for example, after 10 seconds). .

  In the present embodiment, the combinations of the operation modes of the ion generation unit 108 and the blowing unit 110 are limited to two types (that is, the combination of the ion generation amount Na and the blowing amount Wa and the combination of the ion generation amount Nb and the blowing amount Wb). Has been. However, in order to adjust the ion concentration within a predetermined range or the entire room to a required ion concentration, the four types of combinations of the ion generation amounts Na and Nb and the blast amounts Wa and Wb are switched according to the operation of the user 2, for example. But you can. The average ion concentration of the whole room is the lowest in the case of the combination of the ion generation amount Na and the blowing amount Wa, and the highest in the case of the combination of the ion generation amount Nb and the blowing amount Wb. Furthermore, if the blast volume is switched to four stages, the ion concentration can be adjusted more finely.

  Further, the predetermined range is not limited to the range of 50 cm on the front side of the apparatus main body 10. Further, the width of the predetermined range may be switchable according to the operation of the user 2. In this case, the configuration may be such that as the predetermined range is wider / narrower, the ion generation amount Na, the blowing amount Wa, or the illuminance La is automatically switched to a larger / smaller value.

  Furthermore, in the present embodiment, when the set time elapses in the timer operation, the ion generator 1 stops all operations. However, the ion generator 1 in the LED mode may be configured to automatically switch the operation mode from the LED mode to the ion mode without the operation of the operation SW 105 when the set time has elapsed. At this time, in the case of YES in S75, the control unit 112, after executing the processes of S76 and S77, turns off the illumination unit 13 and then moves the process to S65. As a result, after the set time elapses, the illumination unit 13 is turned off while the generation of positive and negative ions by the ion generation unit 108 and the blowing by the blowing unit 110 are continued. For this reason, for example, it is possible to improve the convenience of the user 2 who has forgotten to switch the operation SW 105 from the LED position to the ion position (in other words, forgets to turn off the illumination unit 13).

Moreover, the control part 112 may replace with the process of S60, and may perform the process which makes the illumination part 13 non-lighting. In this case, in the LED mode, when the user 2 does not exist within the predetermined range, for example, when the sleeping user 2 stands in the hand-washing, the illumination unit 13 is turned on. Thereafter, when the user 2 is within the predetermined range, in this case, when the user 2 returns from the hand-washing, the illumination unit 13 is turned off, and the illumination unit 13 is lit as long as the user 2 is within the predetermined range. do not do.
When the non-illuminated illumination unit 13 is turned on, the illumination unit 13 may be first turned on with the illuminance La and automatically switched to the illuminance Lb after an appropriate time has elapsed.

Embodiment 2. FIG.
FIG. 11 is a flowchart showing a procedure of ion generation processing executed by the ion generator 1 according to Embodiment 2 of the present invention.
The hardware configuration of the ion generator 1 in the present embodiment is the same as the hardware configuration of the ion generator 1 in the first embodiment. Hereinafter, differences from the first embodiment will be described, and other parts corresponding to those of the first embodiment are denoted by the same reference numerals and description thereof will be omitted.
Below, the case where the ion generator 1 is made to perform a timer operation by operating the timer SW 106 before going to bed is illustrated.

In the timer operation in the ion mode, as in the first embodiment, when the set time has elapsed, the operation of the ion generator 1 is stopped.
On the other hand, in the LED mode timer operation, when the set time elapses, the illumination unit 13 is turned off. At this time, the operation of each part of the apparatus excluding the illumination unit 13 such as the ion generation unit 108 and the air blowing unit 110 is continued. That is, the LED mode timer operation is useful for preventing the user 2 from forgetting to turn off the illumination unit 13. Further, after the illumination unit 13 is turned off, the illumination unit 13 is turned off or turned on again depending on the presence / absence of the user within a predetermined range.

After the process of S77 shown in FIG. 10 according to the first embodiment is completed, the control unit 112 moves the process to S91 shown in FIG. 11 without moving the process to S65. That is, the control unit 112 turns off the illumination unit 13 (S91). For this reason, regardless of the presence or absence of the user 2 within the predetermined range, the illumination unit 13 is turned off when the set time has elapsed from the start of the timer operation.
The control unit 112 that executes the process of S91 functions as an illumination control unit in the embodiment of the present invention. And the control part 112 which performs the process of S74 functions as a time measuring part in embodiment of this invention.

The elapsed time that should be elapsed by the time measuring unit is not limited to the elapsed time after the timer SW 106 is operated. The elapsed time that should be passed by the time measuring unit is a predetermined operation related to the ion generator 1 (for example, the operation SW 105 is arranged at either the ion position or the LED position, or the user's sleep depth becomes deeper than the predetermined depth. It is sufficient if it is an elapsed time since the determination is made.
After the process of S91 is completed, the control unit 112 executes the process of S92 as in S16.
When an object exists within the predetermined range (YES in S92), the control unit 112 executes the process of S93 as in S17.

When the object existing within the predetermined range is a human (YES in S93), the control unit 112 returns the process to S92.
The case of YES in S93 is a case where the user 2 is sleeping within a predetermined range when the lighting unit 13 is turned off or after the lighting unit 13 is once turned off. At this time, the illumination unit 13 is not turned on. For this reason, there is no possibility that the sleep of the user 2 is disturbed by the light emitted from the illumination unit 13.
When the object does not exist within the predetermined range (NO in S92), or when the object existing within the predetermined range is not a human (NO in S93), the control unit 112 lights the illumination unit 13 with the illuminance Lb ( S94). Next, the control unit 112 executes the processes of S95 and S96 similarly to S73 and S74, and then moves the process to S56.

In the case of NO in S92, that is, when there is no object within the predetermined range, the control unit 112 may execute the process of blinking the illumination unit 13 without moving the process to S94.
The control unit 112 that returns the process to S92 in the case of YES in S93 and the control unit 112 that executes the process of S94 function as the illumination control unit in the embodiment of the present invention.

The case of NO in S92 or S93 is a case where the user 2 moves out of a predetermined range, for example, to stand for hand-washing before the lighting unit 13 is turned off or after the lighting unit 13 is once turned off. At this time, the illumination unit 13 is turned on again. For this reason, the visual field of the user 2 that may exist outside the predetermined range can be brightened by the light emitted from the illumination unit 13.
The lighting unit 13 after re-lighting operates with the illuminance Lb if the user 2 does not exist within the predetermined range, and continues to operate with the illuminance La if it exists, until the set time elapses. If the set time elapses without operating the operation SW 105 or the timer SW 106, the illumination unit 13 is turned off again.

However, when the timer SW 106 is operated before the set time elapses, the timer operation is stopped, and the illumination unit 13 continues to operate at the illuminance La or the illuminance Lb. Further, when the operation SW 105 is operated before the set time elapses, the ion generator 1 ends the operation or operates in the ion mode.
By the way, in the case of NO in S92 or S93, when the user 2 turns over and unintentionally moves outside the predetermined range, or the limb of the user 2 who turns over touches the ion generator 1. If the orientation or orientation of the apparatus main body 10 is changed by this, or the case where a person other than the user 2 accidentally changes the orientation or orientation of the apparatus main body 10 or the like.

In such a case, when the illumination unit 13 is lit with the illuminance Lb, the user 2 can notice that the orientation or orientation of the apparatus main body 10 has changed, and can return the apparatus main body 10 to the correct orientation or orientation.
Note that it is determined that the user 2 exists within the predetermined range, and then it is determined that the user 2 does not exist within the predetermined range. Thereafter, the user 2 exists within the predetermined range even after a predetermined elapsed time has elapsed. When it is not determined, it is considered that the reason why it is determined that the user 2 does not exist within the predetermined range is that the orientation or posture of the apparatus main body 10 has changed. For this reason, the ion generator 1 is good also as a structure which alerts and warns the user 2 by making the illumination part 13 blink.

Embodiment 3. FIG.
FIG. 12 is a front view showing an external configuration of apparatus main body 10b included in ion generating apparatus 1 according to Embodiment 3 of the present invention.
FIG. 13 is a block diagram showing the configuration of the control system of the ion generator 1.
The hardware configuration of ion generator 1 in the present embodiment is substantially the same as the hardware configuration of ion generator 1 in the first and second embodiments. Hereinafter, differences from the first and second embodiments will be described, and other parts corresponding to the first and second embodiments will be denoted by the same reference numerals, and description thereof will be omitted.
12 and 13 correspond to FIGS. 2 and 5 of the first embodiment.

The ion generator 1 in the present embodiment includes a pyroelectric infrared sensor 103b in place of the infrared sensor 103 and the distance measuring sensor 104 in the first and second embodiments.
The pyroelectric infrared sensor 103b detects an object operating within a predetermined range and having a temperature equal to or higher than a predetermined temperature (that is, the user 2 existing within the predetermined range). For this purpose, the pyroelectric infrared sensor 103b has a preset temperature and range to be reacted by a combination of a window material and / or a lens constituting the pyroelectric infrared sensor 103b. When the user 2 exists within the predetermined range, the pyroelectric infrared sensor 103b outputs a presence signal indicating that the user 2 exists within the predetermined range to the control unit 112.
The pyroelectric infrared sensor 103b functions as a living body detection unit in the embodiment of the present invention.

The flowchart of the ion generation process in the present embodiment is substantially the same as the flowchart of the ion generation process in the first and second embodiments.
However, in the case of YES in S12, after the process of S15 is completed, the control unit 112 determines whether or not a presence signal has been input without executing the processes of S16 and S17 (hereinafter, pyroelectric determination process). Execute).

When the presence signal is input, the control unit 112 executes the processes after S18 as in the case where both S16 and S17 are YES. When the presence signal is not input, the control unit 112 executes the processing after S20 as in the case where at least one of S16 and S17 is NO. That is, the flowchart of the ion generation process in the present embodiment is obtained by replacing the processes of S16 and S17 in the first and second embodiments with the pyroelectric type determination process in the present embodiment.
Similarly, in the case of NO in S12, the flowchart of the ion generation process in the present embodiment shows the process of S56 and S57 in the first and second embodiments and the process of S92 and S93 in the second embodiment as a pyroelectric type. This is replaced by the judgment process.

  When the pyroelectric infrared sensor 103b is used, the number of parts constituting the apparatus main body 10 can be reduced. In addition, the number of ion generation processing steps can be reduced. By the way, the pyroelectric infrared sensor 103b has disadvantages such as detecting non-human organisms as humans and being unable to detect the presence or absence of an object having a temperature lower than a predetermined temperature. It is not a big problem in practical use.

Embodiment 4 FIG.
FIG. 14 is a block diagram showing the configuration of the control system of ion generator 1 according to Embodiment 4 of the present invention.
The hardware configuration of ion generator 1 in the present embodiment is substantially the same as the hardware configuration of ion generator 1 in the first and second embodiments. Hereinafter, differences from the first and second embodiments will be described, and other parts corresponding to the first and second embodiments will be denoted by the same reference numerals, and description thereof will be omitted.
FIG. 14 corresponds to FIG. 5 of the first embodiment.
The ion generator 1 in the present embodiment further includes a temperature sensor 116.

  The temperature sensor 116 is disposed in the apparatus main body 10 in order to detect the temperature at a predetermined position (specifically, the position where the temperature sensor 116 is arranged, and thus the vicinity of the ion generator 1). The detection result of the temperature sensor 116 is given to the control unit 112. The temperature sensor 116 may be arranged on the arm unit 11 or the support base 12. The temperature sensor 116 functions as a temperature detection unit in the embodiment of the present invention.

By the way, since the humidity is low in winter, activities such as fungi and viruses that cause a cold or influenza are prosperous, and rough skin or itching is likely to occur due to dryness. The positive and negative ions generated by the ion generator 108 of the present embodiment are cluster ions due to the attachment of a large amount of moisture in the air. Therefore, it is possible to suppress the user 2 from being afflicted with a cold, influenza, or the like, or causing trouble in the user 2's skin during winter, by particularly increasing the ion concentration.
Therefore, eight ion generation amount candidate values a1 to a4 and b1 to b4 (0 <a1 <a2 <a3 <a4, 0 <b1 <b2 <b3 <b4) are given to the control unit 112 in advance. .

  The control unit 112 acquires the detection result of the temperature sensor 116 at an appropriate timing. When the acquired detection result is 10 ° C. or lower, the control unit 112 uses the ion generation amount candidate values a4 and b4 as the ion generation amounts Na and Nb. When the acquired detection result is more than 10 ° C. and 20 ° C. or less, the control unit 112 uses the ion generation amount candidate values a3 and b3 as the ion generation amounts Na and Nb. Similarly, when the acquired detection result is 20 ° C. or more and 30 ° C. or less (or 30 ° C. or more), the control unit 112 ionizes the ion generation amount candidate values a2 and b2 (or the ion generation amount candidate values a1 and b1). Used as generated amounts Na and Nb.

As a result, the efficacy of positive and negative ions can be increased by increasing the amount of ion generation in the season when the ion concentration should be increased. On the other hand, it is possible to contribute to energy saving by reducing the amount of ions generated in the season when it is not necessary to increase the ion concentration.
As described above, the ion generation amount control unit of the control unit 112 in which the ion generation amounts Na and Nb are set executes the processing of S19, the processing of S21, and the processing of S59 and the processing of S62. The adjustment unit 115 functions as an ion generation amount adjustment unit in the embodiment of the present invention.

In addition, the number of temperature divisions and ion generation amount candidate values is not limited to 4 divisions and 8 pieces. Moreover, the temperature used as a criterion is not limited to 10 ° C, 20 ° C, and 30 ° C.
For example, hay fever has a peak in spring and autumn respectively, so it is desirable to increase the ion concentration, if not as much as in winter. In summer, when the humidity is high and pollen that is an allergen is less scattered, there is no particular problem even if the ion concentration is low. Therefore, the temperature classification may be divided into three classifications: winter, spring and autumn, and summer. Moreover, it is good also considering the temperature used as a determination reference | standard according to the climate of the area where the ion generator 1 is shipped.

The embodiment disclosed this time is to be considered as illustrative in all points and not restrictive. The scope of the present invention is not intended to include the above-described meanings, but is intended to include meanings equivalent to the claims and all modifications within the scope of the claims.
Moreover, as long as there exists an effect of this invention, the component which is not disclosed by Embodiment 1-4 may be contained in the ion generator 1. FIG.
Below, some ion generators are appended.
[1]
An ion generator is an ion generator that includes an ion generator that generates ions and a blower that sends out ions generated by the ion generator to the outside of the apparatus. An air volume adjustment that adjusts an air flow rate of the air blowing unit when the living body detecting unit detects the presence of a living body to be smaller than the air flow rate when the absence of the living body is detected. And a section.
[2]
The ion generator adjusts the illumination unit that illuminates the predetermined range and the illumination unit when the living body detection unit detects the presence of a living body to be darker than the illumination unit when the absence of the living body is detected. And an illumination adjustment unit.
[3]
An ion generator is an ion generator that includes an ion generator that generates ions and a blower that sends out ions generated by the ion generator to the outside of the apparatus. A living body detecting unit that detects the presence of the living body, and an illuminating unit that illuminates the predetermined range; And an illumination adjustment unit that adjusts the brightness to be adjusted.
[4]
The ion generator includes a timer unit for measuring an elapsed time from a predetermined operation, and when the timer unit measures a predetermined elapsed time, the illumination unit is turned off, and the living body detection is performed after the illumination unit is turned off. And an illumination control unit that turns on the illumination unit when the unit detects the absence of a living body.
[5]
An ion generator includes a temperature detection unit that detects a temperature at a predetermined position, and when a detection result of the temperature detection unit is equal to or lower than a predetermined temperature, the ion generation amount of the ion generation unit is increased and the predetermined temperature is increased. It is further characterized by further comprising an ion generation amount adjusting unit that reduces the amount when it is excessive.
[6]
An ion generation device includes: an ion generation amount adjustment unit configured to reduce an ion generation amount of the ion generation unit when the biological detection unit detects the presence of a living body to be smaller than the ion generation amount when the absence of the biological body is detected. It is further provided with the feature.
[7]
The ion generation device includes an ion generation unit, an air blowing unit, a living body detection unit, and an air volume adjustment unit.
The living body detection unit detects whether or not a living body exists within a predetermined range. Here, the living body is a user of the ion generator. The predetermined range in which the presence / absence of the living body should be detected is a range in which ions generated in the ion generation unit are directly sent out at a preferable concentration together with the air blown by the blower unit. This is a range in which a user is highly likely to exist. When the generated ions have both positive and negative polarities, they attract each other and disappear in the air, so that a range in which a predetermined concentration can be maintained is automatically determined. Outside the predetermined range, ions having a predetermined concentration or less are diffused by air convection or circulation.
The air volume adjusting unit adjusts the air volume of the air blowing unit according to the detection result of the living body detecting unit. As a result, when the living body detection unit detects the presence of a living body, the blowing amount of the blowing unit is relatively small, and when the living body detection unit detects the absence of a living body, the blowing amount of the blowing unit is relatively large. Become.
When the blown amount is small, the ion concentration outside the predetermined range is unlikely to be high. However, the case where the amount of blown air is small is a case where the user is present within the predetermined range. Therefore, if the ion concentration within the predetermined range is sufficiently high, there is no particular problem even if the ion concentration outside the predetermined range is low. . In addition, the volume of the operating sound and the blowing sound of the blower is reduced by the amount of the blown air, and further, the amount of energy consumed by the blower is reduced. That is, it contributes to energy saving.
By the way, when the user does not exist within the predetermined range, there is a possibility that the user exists outside the predetermined range. In this case, since the amount of blown air is large, the ion concentration tends to be high regardless of the inside or outside of the predetermined range. Therefore, a sufficient concentration of ions is supplied even to a user who is outside a predetermined range where ions are not directly delivered.
[8]
The ion generation apparatus further includes an illumination unit and an illumination adjustment unit in addition to the ion generation unit, the air blowing unit, the living body detection unit, and the air volume adjustment unit, or the ion generation unit, the air blowing unit, the biological detection unit, and the illumination unit. And an illumination adjustment unit.
The illumination adjustment unit adjusts the brightness of the illumination unit according to the detection result of the living body detection unit. As a result, when the living body detection unit detects the presence of a living body, the illumination unit becomes relatively dark. When the living body detection unit detects the absence of a living body, the lighting unit becomes relatively bright.
When the user exists within the predetermined range, the predetermined range is not excessively brightly illuminated, so there is no possibility that the user existing within the predetermined range will feel dazzled. Furthermore, the amount of energy consumed by the lighting unit is reduced by the amount of darkness in the lighting unit. That is, it contributes to energy saving.
When there is no user within the predetermined range, there is a possibility that the user exists outside the predetermined range. In this case, since the illumination part is bright, the inside and outside of the predetermined range are illuminated brightly as a whole. Therefore, the field of view of the user existing outside the predetermined range is sufficiently secured.
[9]
The ion generator further includes a timer unit and an illumination control unit.
The timer unit measures the elapsed time from the predetermined operation.
The lighting control unit turns off the illuminating unit that is turned on when the time measuring unit measures a predetermined elapsed time, and turns off the illuminating unit when the living body detecting unit detects the absence of the living body after the lighting unit is turned off. Light. When the living body detecting unit detects the presence of the living body after the lighting unit is turned off, the lighting control unit does not turn on the lighting unit.
Such an ion generator is, for example, an illuminating unit caused by a user having gone to sleep with the illuminating unit turned on by turning off the illuminating unit after a predetermined elapsed time since the user operated the ion generating device. You can prevent forgetting to turn off. Moreover, since the user who exists in the predetermined range after light extinction has already fallen asleep, the user's sleep is not hindered by turning off the illumination unit, and contributes to energy saving. Further, when the sleeping user moves out of a predetermined range, for example, by standing on his hand, the user's field of view is ensured by relighting the illumination unit.
[10]
The ion generator further includes a temperature detection unit and an ion generation amount adjustment unit.
The temperature detection unit detects the temperature at a predetermined position. The ion generation amount adjustment unit increases or decreases the ion generation amount of the ion generation unit according to the detection result of the temperature detection unit.
The detection result of the temperature detection unit is accumulated, for example, in the control unit of the ion generator. A control part calculates | requires the minimum daily temperature from the accumulated detection result, and when the calculated | required minimum temperature is 15 degrees C or less, it determines with it being an intermediate period or winter season. For this reason, the relationship between the time or season and the minimum temperature is given to the control unit in advance. In winter, the activities of fungi and viruses that cause colds and influenza are thriving, so the ion generator generates a large amount of ions. Also, in the spring season when pollen such as cedar and cypress is scattered and in the autumn season when pollen such as ragweed and mugwort is scattered, the ion generating part generates a large amount of ions.
[11]
The ion generator further includes an ion generation amount adjustment unit.
The ion generation amount adjustment unit adjusts the ion generation amount of the ion generation unit according to the detection result of the living body detection unit. As a result, when the living body detection unit detects the presence of the living body, the ion generation amount of the ion generation unit is relatively small, and when the living body detection unit detects the absence of the living body, the ion generation amount of the ion generation unit is Relatively more.
When the amount of blown air and the amount of generated ions are small, the ion concentration outside the predetermined range is less likely to become higher. However, when the user exists within the predetermined range, there is no particular problem even if the ion concentration outside the predetermined range is low if the ion concentration within the predetermined range is sufficiently high. Moreover, the amount of energy consumed by the ion generator is reduced by the amount of generated ions. That is, it further contributes to energy saving.
On the other hand, when the amount of blown air and the amount of generated ions are large, the ion concentration tends to be higher regardless of the inside or outside of the predetermined range. Therefore, a sufficient concentration of ions is supplied even to a user who is outside a predetermined range where ions are not directly delivered.
[12]
In the case of the ion generator, the ion concentration around the user can be efficiently increased according to the presence or absence of a living body within a predetermined range.
For example, when the user exists within a predetermined range, the air blowing amount decreases. For this reason, it is possible to efficiently increase the ion concentration within a predetermined range, that is, the ion concentration around the user without sacrificing quietness and contributing to energy saving. On the other hand, when the user wakes up outside the predetermined range, the air flow rate increases. For this reason, the ion concentration inside and outside the predetermined range, that is, the ion concentration around the user can be efficiently increased.
[13]
In the case of the ion generator, the brightness around the user can be appropriately adjusted according to the presence or absence of a living body within a predetermined range.
For example, when the user exists within a predetermined range, the illumination unit becomes dark. For this reason, an illumination part does not become too bright. And it can contribute to energy saving. On the other hand, when the user exists outside the predetermined range, the illumination unit becomes bright. For this reason, a lighting part is too dark, and a user does not feel inconvenient or encounter a dangerous eye.
