Description

  The present invention relates to a technique for generating charged fine particle water by utilizing an electrostatic atomization phenomenon.

  Conventionally, an atomizing electrode, water supply means for supplying water to the atomizing electrode, and a high voltage generating circuit for applying a high voltage to the atomizing electrode, the water supplied to the atomizing electrode is 2. Description of the Related Art There is known an electrostatic atomizer that electrostatically atomizes with a high electric field generated by application of voltage to generate charged fine particle water containing radicals.

  Currently, the electrostatic atomizer as described above is mounted on an electric device. The charged fine particle water containing radicals generated by the electrostatic atomizer contains radicals and has a long life, so that it can be diffused in the air in large quantities, effectively acting on malodorous components, etc. and deodorizing. It is also effective for moisturizing the skin.

  However, the electrostatic atomizer as described above has a problem that there is a large variation with respect to the rated voltage of the high voltage output from the high voltage generation circuit due to individual variation of the high voltage generation circuit. That is, in the high voltage generation circuit, since the output value of the high voltage is determined by the component constant used, when the variation of the component constant used is large, the variation of the high voltage with respect to the rated voltage becomes large. A high voltage generation circuit in which the variation in high voltage is too large cannot secure an amount of charged fine particles effective for deodorization and skin moisturization. For such a high voltage generation circuit where the variation in the high voltage is too large, the high voltage must be adjusted by replacing components. For this reason, there is a demand to stably adjust the output variation of high voltage to the rated voltage.

Moreover, in the electrostatic atomizer incorporated in the electric equipment, since the switching frequency when generating a high voltage is arbitrarily determined by the high voltage generator, the switching frequency of the high voltage generator is In some cases, the reception frequency of the infrared remote control receiving unit in an electric device such as a home air conditioner in which is embedded overlaps with the reception frequency, and the electric device may malfunction.

  The present invention has been invented in view of the above-described conventional problems, and adjusts variations in high voltage output due to variations in individual high voltage generation circuits and does not cause malfunctions of mounted electrical equipment. An object of the present invention is to provide an electrostatic atomizer.

  The electrostatic atomizer 5 according to the present invention outputs a high voltage by the atomization electrode 1, a water supply means 2 for supplying water to the atomization electrode 1, and a high voltage control signal output by the control means 4. A high voltage generating circuit 3 for applying a high voltage to the atomizing electrode 1, and electrostatically atomizing the water supplied to the atomizing electrode 1 with a high electric field generated by the application of the high voltage. is there. A feature of the present invention is that the control means 4 detects a high voltage output from the high voltage generation circuit 3 and, based on the detected value, the high voltage becomes a predetermined high voltage required for electrostatic atomization. A high voltage adjusting means 11 for adjusting the frequency and a frequency adjusting means 12 for adjusting the switching frequency of the high voltage control signal output from the control means 4 for driving the switching of the high voltage generating circuit 3 are provided. The switching frequency is included in the specific frequency range such that the high voltage output from the high voltage generation circuit 3 becomes a predetermined high voltage necessary for electrostatic atomization by the frequency adjusting means 11, and In other words, the adjustment is made so as not to fall within the reception frequency range of the infrared remote control receiver 14 in the electric device 13 in which the electrostatic atomizer 5 is incorporated.

  With this configuration, the high voltage output from the high voltage generation circuit 3 due to individual variations in the high voltage generation circuit 3 is adjusted with respect to the rated voltage by the high voltage adjustment unit 11 provided in the control unit 4. The high voltage output from the high voltage generation circuit 3 can be adjusted to the rated voltage. Further, the frequency adjusting means 12 determines the switching frequency of the high voltage control signal for driving the switching of the high voltage generation circuit 3, and the high voltage output from the high voltage generation circuit 3 is a predetermined required for electrostatic atomization. Is adjusted to a range that does not fall within the reception frequency range included in the infrared remote control receiver 14 in the electrical device 13 in which the electrostatic atomizer 5 is incorporated. Thus, the switching of the high voltage generation circuit 3 can prevent the electric device 13 in which the electrostatic atomizer 5 is incorporated from malfunctioning.

  The high voltage control signal for driving the high voltage generation circuit 3 output from the control means 4 is preferably a pulse width modulation system.

  With this configuration, it is possible to control the high voltage output from the high voltage generation circuit 3 in a fixed state.

  Since the present invention is configured as described above, the high voltage output variation due to the fixed variation of the high voltage generation circuit is adjusted by the high voltage adjustment unit provided in the control unit, and the output value of the high voltage is set to the rated voltage. Therefore, it is not necessary to adjust by means such as replacement of parts or variable resistance, and the production cost can be reduced. In addition, switching of the high voltage generation circuit can be prevented from affecting the remote control receiving unit of the electric device in which the electrostatic atomizer is incorporated, and malfunction of the electric device can be prevented.

  In addition, since the high voltage control signal for driving the high voltage generation circuit output from the control means is a pulse width modulation method, it can be controlled with the switching frequency of the high voltage generation circuit fixed, It is possible to prevent the remote control receiving unit of the electrical equipment in which the electrostatic atomizer is incorporated from being affected.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 is a control block diagram of the electrostatic atomizer 5 of the present invention. The electrostatic atomizer 5 includes an atomizing electrode 1, a water supply means 2 for supplying water to the atomizing electrode 1, and an atomizing electrode 1 for electrostatically atomizing water supplied to the atomizing electrode 1. And a high voltage generation circuit 3 for applying a high voltage to the water supplied to the water. In FIG. 1, 4 is a control means comprising a microcomputer, 9 is a discharge current detection circuit, 10 is a high voltage detection circuit, 3 is a high voltage generation circuit, 5a is an atomization block, 7 is a Peltier power supply circuit, and 20 is It is a Peltier voltage detection circuit.

  In the embodiment shown in the accompanying drawings, an example is shown in which the water supply means 2 is constituted by a cooling means for supplying water to the atomizing electrode 1 by generating moisture in the air as condensed water. .

  In the embodiment shown in FIG. 1, the cooling means is constituted by the Peltier unit 6, and water is supplied to the atomizing electrode 1 by generating moisture by cooling the moisture in the air by the cooling means. ing.

  The Peltier unit 6 has a pair of Peltier circuit boards in which a circuit is formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity, facing each other so that the circuits face each other, and arranged in multiple rows. A BiTe-based thermoelectric element is sandwiched between both Peltier circuit boards, and adjacent thermoelectric elements are electrically connected by circuits on both sides, and the Peltier power supply circuit 7 formed via a Peltier input lead wire is transferred to the thermoelectric element. Is configured such that heat is transferred from one Peltier circuit board side to the other Peltier circuit board side. Further, a cooling part is connected to the outside of the Peltier circuit board on one side, and a heat radiating part is connected to the outside of the Peltier circuit board on the other side. Can be illustrated. The rear end of the atomizing electrode 1 is connected to the cooling part of the Peltier unit 6.

  In the embodiment shown in the accompanying drawings, a counter electrode 8 is disposed so as to face the atomizing electrode 1. And in embodiment shown to an accompanying drawing, the atomization block 5a is comprised by the Peltier unit 6, the atomization electrode 1, and the counter electrode 8. FIG.

  In the electrostatic atomizer 5 having the above-described configuration, the cooling unit is cooled by energizing the Peltier unit 6, the atomizing electrode 1 is cooled by cooling the cooling unit, and moisture in the air is condensed. Water (condensation water) is supplied to the atomizing electrode 1.

  When a high voltage is applied from the high voltage generation circuit 3 between the atomizing electrode 1 and the counter electrode 8 in a state where water is supplied to the atomizing electrode 1 in this way, the atomization electrode 1 and the counter electrode 8 The Coulomb force acts between the water supplied to the tip of the atomizing electrode 1 and the counter electrode 8 due to the high voltage applied between them, and the water level rises locally in a cone shape (tailor cone). It is formed. When the tailor cone is formed in this way, the electric charge concentrates on the tip of the tailor cone and the electric field strength in this portion increases, thereby increasing the Coulomb force generated in this portion and further growing the tailor cone. . When the tailor cone grows like this and the charge concentrates on the tip of the tailor cone and the density of the charge becomes high, the water at the tip of the tailor cone has a large energy (repulsive force of the charge that has become dense). In response to this, a large amount of nanometer-sized charged fine particle water charged negatively or positively is generated by repeating splitting and scattering (Rayleigh splitting) beyond the surface tension. The generated charged fine particle water is discharged to the outside of the electrostatic atomizer 5.

  Then, based on the cooling control signal output from the control means 4, a cooling voltage is output from the Peltier power supply circuit 7 to the Peltier unit 6, and moisture in the air is generated as condensed water by the cooling action of the Peltier unit 6. Thus, dew condensation water is supplied to the tip of the atomizing electrode 1.

  When a high voltage control signal is output from the control means 4 in this state, a high voltage is output from the high voltage generation circuit 3 based on the high voltage control signal, and a high voltage is applied to the atomizing electrode 1 as described above. Electrostatic atomization of water at the tip of the atomizing electrode 1 is performed, and nanometer-sized charged fine particle water is generated.

  Here, the discharge current detection circuit 9 detects the current during discharge, the discharge current detection circuit 9 outputs a discharge current signal to the control means 4, and the control means 4 generates a high voltage based on the discharge current signal. The circuit 3 and the Peltier power supply circuit 7 are PWM-controlled.

  The electrostatic atomizer 5 as described above is incorporated in an electric device 13 having an infrared remote control receiver 14. Examples of the electric device 13 incorporating the electrostatic atomizer 5 include a home air conditioner and an air cleaner controlled by an infrared remote controller, but are not necessarily limited to the above example, and are controlled by the infrared remote controller. Other electrical devices may be used as long as they are electrical devices.

  Here, the electrostatic atomizer 5 of the present invention incorporated (mounted) in the electric device 13 as described above detects the high voltage output from the high voltage generation circuit 3 in the control means 4 and detects the detected high voltage. The high voltage adjusting means 11 for adjusting the high voltage to a predetermined high voltage necessary for electrostatic atomization based on the value and the control means 4 for driving the switching of the high voltage generating circuit 3 are output. The Peltier power supply circuit 7 is driven by the frequency adjusting means 12 for adjusting the switching frequency of the high voltage control signal and the cooling control signal of the frequency adjusted under the same conditions as the switching frequency adjusting conditions by the frequency adjusting means 12. Peltier voltage control means 15 is provided.

  Adjustment of the high voltage output from the high voltage generation circuit 3 by the high voltage adjustment means 11, adjustment of the switching frequency of the high voltage control signal output from the control means 4 by the frequency adjustment means 12, adjustment of the switching frequency for Peltier, Adjustment of the voltage output from the Peltier power supply circuit 7 by the Peltier voltage control means 15 is automatically performed when the electrostatic atomizer 5 is initially set.

  In the initial setting, first, control for adjusting the switching frequency by the frequency adjusting unit 12 provided in the control unit 4 is performed.

  That is, since the natural frequency of the high voltage generation circuit 3 varies depending on the individual, the high voltage control from the control unit 4 to the high voltage generation circuit 3 is performed by the frequency adjusting unit 12 according to the natural frequency of the high voltage generation circuit. Infrared remote control receiver 14 in an electric device 13 that is included in a specific frequency range that can secure the high voltage required for electrostatic atomization by controlling the frequency output of the signal and that incorporates the electrostatic atomizer 5 Adjust to a range that does not fall within the reception frequency range of the.

  FIG. 2 shows an example of a control flow diagram.

  In the present embodiment, a high voltage control signal (PWM duty fixed, frequency is an initial value) is output from the control means 4, high voltage output is started from the high voltage generation circuit 3, and the high voltage detection circuit 10 increases the high voltage. A voltage is detected, a high voltage signal is input to the control means 4 and a high voltage output is read. Next, when the frequency is increased by Δf by one step and the high voltage output when the frequency is increased by Δf decreases (the high voltage signal value decreases), the frequency is decreased by one step by Δf and the frequency is decreased by Δf. If the high voltage rises (the high voltage signal value increases), it is determined whether or not the frequency limit value (the upper limit value of the reception frequency range of the infrared remote control receiver 14) has been exceeded. When the value is exceeded, the switching frequency is determined at a frequency one step before the above-exceeded frequency (see FIG. 3).

  If the frequency limit value is not exceeded, the frequency is again decreased by one step by Δf.

  On the other hand, if the high voltage drops when the frequency is decreased by Δf (the high voltage signal value decreases), it can be recognized that the peak frequency has been exceeded, so the frequency is increased by Δf by one step and the high voltage peaks. The frequency is returned to the frequency immediately before falling below the frequency, and this frequency is regarded as the peak frequency and determined as the switching frequency (see FIG. 4).

  Also, in the control flow diagram of FIG. 2, the high voltage generation circuit 3 starts high voltage output, reads the high voltage output, and then increases the high voltage when the frequency is increased by one step by Δf ( When the high voltage signal value is increased), the frequency is increased by Δf, and when the frequency is increased by Δf, the high voltage is increased (the high voltage signal value is increased). 14 is exceeded, and if the frequency limit value is exceeded, the switching frequency is determined at a frequency one step before the above-exceeded frequency. If the frequency limit value is not exceeded, the frequency is again increased by one step by Δf (see FIG. 5).

  On the other hand, if the high voltage rises when the frequency is increased by Δf (the high voltage signal value increases), it can be recognized that the peak frequency has been exceeded, so the frequency is decreased by one step by Δf, and the high voltage is increased. The frequency is returned to the frequency just before falling below the peak frequency, and this frequency is regarded as the peak frequency and determined as the switching frequency.

  FIGS. 3 to 6 are explanatory diagrams for explaining the order of examples in which the switching frequency is adjusted by the control flow of FIG.

  FIG. 3 shows a case where the initial value of the switching frequency is (1), and when the frequency is first increased by one step (Δf), the high voltage output is decreased (the high voltage signal value is decreased). Is decreased by Δf, and when the frequency is decreased to (2), (3)... (N), the frequency (N) becomes the frequency limit value before the high voltage output changes from rising to falling. In this case, an example is shown in which (M) obtained by increasing the frequency by one step (Δf) from (N) where the frequency limit value is first exceeded is determined as the switching frequency.

  FIG. 4 shows a case where the initial value of the switching frequency is (1), and when the frequency is first increased by one step (Δf), the high voltage output is decreased (the high voltage signal value is decreased). Is reduced by Δf and the frequency is reduced to (2), (3), ... (N). In this case, the high voltage output changes from rising to falling and the frequency is increased by one step (Δf) from the frequency (N) and (M) is determined as the switching frequency. Yes.

  FIG. 5 shows a case where the initial value of the switching frequency is (1) and the high voltage output is increased (the high voltage signal value is increased) when the frequency is first increased by one step (Δf). When the frequency is increased by Δf and the frequency is increased from (2) to (N), the frequency (N) exceeds the frequency limit value before the high voltage output changes from rising to falling. In this case, an example is shown in which (M) in which the frequency is reduced by one step (Δf) from (N) that first exceeds the frequency limit value is determined as the switching frequency.

  FIG. 6 shows a case where the initial value of the switching frequency is (1) and the high voltage output increases (the high voltage signal value increases) when the frequency is first increased by one step (Δf). When the frequency is increased by Δf and the frequency is increased to (2)... (N), the frequency limit value will not be exceeded even if the high voltage output changes from rising to falling to become the frequency (N). In this case, an example is shown in which the high voltage output is changed from rising to falling, and (M) obtained by reducing the frequency by one step (Δf) from the frequency (N) is determined as the switching frequency.

  In this way, after the frequency adjustment means 12 provided in the control means 4 adjusts the frequency of the high voltage control signal for driving the switching of the high voltage generation circuit 3 and automatically determines the switching frequency, The high voltage output from the high voltage generation circuit 3 by the voltage adjusting means 11 is automatically adjusted so as to be a predetermined high voltage necessary for electrostatic atomization.

  That is, the high voltage generating circuit 3 of the electrostatic atomizer 5 has individual variations depending on the component constants incorporated therein, and there is variation with respect to the rated voltage of the high voltage output from the high voltage generating circuit 3. For this reason, in the present invention, by providing the control means 4 with the high voltage adjusting means 11, the high voltage output from the high voltage generating circuit 3 is detected, and the high voltage adjusting means 11 detects the high voltage based on the detected value. The voltage is automatically adjusted so as to be a predetermined high voltage necessary for electrostatic atomization.

  Here, in the present invention, the high voltage generation circuit 3 is not provided with a DCDC controller IC or a switching circuit as in the prior art, and a pulse width modulation method adjusted by the high voltage adjustment means 11 provided in the control means 4 is used. A switching element provided in the high voltage generation circuit 3 is directly turned on and off by a high voltage control signal.

  FIG. 7 shows a flow chart of the control of the high voltage adjustment by the high voltage adjusting means 11, and the adjustment of the high voltage will be described based on FIG.

  A high voltage control signal (PWM duty fixed, frequency is the frequency obtained above) is output from the control means 4, and high voltage output from the high voltage generation circuit 3 is started. The high voltage output from the high voltage generation circuit 3 is detected by the high voltage detection circuit 10, and the detected discharge voltage signal is read by the high voltage adjustment means 11 provided in the control means 2 and detected by the high voltage detection circuit 10. If the detected high voltage is the rated voltage, the duty ratio of the high voltage control signal output from the control means 4 is maintained, while the detected high voltage is If it is not the rated voltage, the duty ratio of the high voltage control signal output from the control means 4 is changed and adjusted so that the high voltage becomes the rated voltage. When the high voltage becomes the rated voltage, the duty ratio of the high voltage control signal is changed. maintain. Thus, the high voltage adjusting means 11 detects the high voltage output from the high voltage generating circuit 3 and adjusts the high voltage to be a rated voltage necessary for electrostatic atomization based on the detected value.

  Further, the control means 4 is provided with the Peltier voltage control means 15 as described above, and the Peltier power control circuit 15 uses the cooling control signal having the same frequency as the switching frequency obtained by the frequency adjustment means 12 by the Peltier voltage control means 15. 7 is adjusted to drive.

  Here, in the present invention, the Peltier power supply circuit 7 is not provided with a DCDC controller IC or a switching circuit as in the prior art, and a pulse width modulation method adjusted by the Peltier voltage control means 15 provided in the control means 4 is used. A switching element provided in the Peltier power supply circuit 7 is directly turned on and off by a cooling control signal.

  FIG. 8 shows a flow chart of control of the Peltier voltage adjustment by the high voltage adjusting means 11, and the adjustment of the Peltier voltage will be described based on FIG.

  A cooling control signal (PWM duty fixed, frequency is set to the same frequency as the switching frequency obtained by adjusting the frequency adjusting means 12) is output from the control means 4, and voltage output is started from the Peltier power supply circuit 7. . The voltage output from the Peltier power supply circuit 7 is detected by the Peltier voltage detection circuit 20, and the detected Peltier voltage signal is read by the high voltage adjusting means 11 provided in the control means 2 and detected by the Peltier voltage detection circuit 20. It is determined whether the voltage is the target voltage. If the detected voltage is the target voltage, the duty ratio of the cooling pressure control signal output from the control unit 4 is maintained, while the detected high voltage is not the target voltage. In this case, the duty ratio of the cooling control signal output from the control means 4 is changed and adjusted so that the voltage becomes the target voltage. When the voltage becomes the target voltage, the duty ratio of the cooling control signal is maintained.

  As described above, in the initial setting of the electrostatic atomizer 5, the switching frequency is adjusted by the frequency adjusting unit 12, and the switching frequency of the high voltage generating circuit 3 is output to the high voltage generating circuit 3. The reception frequency of the infrared remote control receiver 14 in the electrical device 13 that is included in the specific frequency range in which the voltage is a predetermined high voltage necessary for electrostatic atomization and in which the electrostatic atomizer 5 is incorporated. Since the switching frequency of the Peltier power supply circuit 7 is set to the same frequency as the switching frequency set in this way, the switching of the high voltage generating circuit 3 and the switching of the Peltier power supply circuit 7 are set. However, the electric device 13 in which the electrostatic atomizer 5 is incorporated can be prevented from malfunctioning.

  Further, the high voltage adjusting means 11 provided in the control means 4 detects the high voltage output from the high voltage generating circuit 3, and based on this high voltage detection signal, the high voltage output from the high voltage generating circuit 3 is set to the rated voltage. Further, the voltage output from the Peltier power supply circuit 7 is detected by the Peltier voltage control means 15, and the Peltier voltage output from the Peltier power supply circuit 7 based on this voltage detection signal is set as the target voltage. Therefore, the individual variations of the high voltage generation circuit 3 and the Peltier power supply circuit 7 are adjusted by the control means 4 so that the high voltage output from the high voltage generation circuit 3 is adjusted to the rated voltage and the Peltier power supply The voltage output from the circuit 7 can be adjusted to the target voltage.
