[0001]

The present invention relates to an ozonizer that generates ozone using surface discharge and an ozone deodorizer using the ozonizer.

[0002]

2. Description of the Related Art Among substances existing in nature, ozone is an oxidizing agent having a strong oxidizing power after fluorine, and finally decomposes and returns to oxygen. Has been widely developed (for example,
-25524). Various ozonizers are employed in the ozone deodorizer.

[0003] For example, an ozonizer 101 shown in FIG.
Dielectric 1 sandwiched between induction electrode 131 and discharge electrode 132
33, and both electrodes 131 and 132 have a wiring L
A high-voltage applying means (not shown) capable of applying a high-frequency high voltage is electrically connected thereto via the. According to this configuration, ozone can be generated by applying a high-frequency high voltage to both electrodes 131 and 132 and causing a high-frequency creeping discharge from discharge electrode 132 to the surface of dielectric 133. Then, this ozone and N, which is a malodorous component in the air,
By mixing with Ox or SOx, these malodorous components are oxidized and deodorized. Here, when the humidity of the raw material air for generating ozone is high,
In addition to not being able to generate ozone sufficiently, dew condensation may occur on the surface of the dielectric 133, which may cause a failure in starting the ozonizer 101. For this reason, in the conventional ozonizer 101, a heater 134 is provided on the dielectric 133, and the heater 134 is activated when the ozonizer 101 is activated to evaporate water. Further, in order to firmly fix the ozonizer 101 and the heater 134, both are covered with a resin holder 135.

[0004]

As described above, when the heater 134 is provided on the dielectric 133 of the ozonizer 101 and the heater 134 is activated when the ozonizer 101 is activated, the ozone raw material air is dried. In addition, moisture adhering to the dielectric 133 can be removed.

As a result, the odorous components contained in the air to be deodorized
And deliquescent such as ammonium nitrate and ammonium sulfate
Salt (mainly NH_FourNO _ThreeYa (NH_Four)_TwoSO_Four
Etc.) are deposited on the surface of the dielectric 133 as precipitates S, and
It absorbs moisture in the air and adheres to the surface of the dielectric 133.
Especially in the holder type ozonizer 101 mentioned above.
The surface discharge portion is covered by the holder 135
The holder 135 has a large number of holes at the open end.
The precipitate S will adhere.

If a large number of such precipitates S adhere, the discharge between the electrodes 131 and 132 becomes extremely unstable, and there is a problem that ozone cannot be generated. It is known that the precipitate S can be made acicular by heating the dielectric 133 with the heater 134. However, merely making the precipitate S needle-shaped could not sufficiently stabilize the discharge, and was not practical.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows an ozone deodorizer A using an ozonizer 10 according to an embodiment of the present invention.
2 shows a schematic sectional view of FIG. Referring to the figure, the ozone deodorizer A includes a casing A1 for introducing the processing air in the room C into the inside. The casing A1 is a hollow article having an air inlet A2 for introducing air into the inside, and an air outlet A3 for discharging the introduced air. A pre-filter A4 for removing dust of air to be deodorized is provided at the air inlet A1. And
The ozonizer 10 is disposed downstream of the prefilter A4, and an ozone decomposition filter A5 for decomposing ozone generated by the ozonizer 10 is disposed downstream of the ozonizer 10. A fan A6 is provided downstream of the ozone decomposition filter A5, and air is introduced into the casing A1 by the fan A6. A diffusion plate A is provided between the ozonizer 10 and the ozone decomposition filter A5.
7 are provided. The diffusion plate A7 is an ozonizer 10
The ozone generated by the filter is uniformly distributed by the ozone decomposition filter A.
5 to diffuse the ozone.

The ozonizer 10 has a dielectric 13 sandwiched between an induction electrode 11 and a discharge electrode 12, and a heater 14 for heating the dielectric 13. The dielectric 13 is made of a plate piece made of fine ceramic, borosilicate glass, or the like. The induction electrode 11 is embedded in the dielectric 13 and the discharge electrode 12 is
And forms a predetermined gap with the induction electrode 11. However, the induction electrode 11 does not necessarily need to be buried, and is provided on the back surface of the dielectric 13.
You may make it oppose the discharge electrode 12 arrange | positioned at the surface side.

The electrodes 11 and 12 and the heater 14 are electrically connected to a control device 17 as a control means including a power supply device via power supply circuits 15 and 16, respectively. A high voltage generator (not shown) for applying a sine wave or pulse high frequency high voltage to each of the electrodes 11 and 12 is electrically connected to the power supply circuit 15 connected to each of the electrodes 11 and 12. It is connected.

On the other hand, the power supply circuit 16 is connected to the heating wire 14a of the heater 14 to apply a predetermined voltage to the heating wire 14a when the voltage is applied to both the electrodes 11, 12. Although not specifically shown, the power supply circuit 16 includes a delay circuit for delaying the stop of power supply to the heating wire 14a, and after the application to both the electrodes 11 and 12 is completed,
After a lapse of a predetermined time, the suspension of power supply to the heating wire 14a is delayed.

The control device 17 is also electrically connected to the fan A6 via a circuit 18 so that the fan A6 can be controlled to a desired rotation speed. Here, the capacity of the heater 14 is set to, for example, 6 such that the temperature of the dielectric 13 at the time of heating becomes a temperature at which the precipitate attached to the surface of the dielectric 13 can be scattered (hereinafter referred to as “scattering temperature”).
Set to watts.

Next, the scattering temperature will be described with reference to FIG. FIG. 2 shows the temperature of the room C = 23 ° C. and the humidity =
50% RH, concentration of malodorous component (ammonia) = 1 pp
Under the measurement conditions of m and operation time = 24 hours, the temperature of the dielectric substance 13, the ozone generation ratio Rt, and the amount of deposit (ammonium salt) attached (mg / day) were measured. Is a graph of the relationship.

First, as shown by X1, the ozone generation ratio Rt is largest when the temperature of the dielectric 13 is 100 ° C.
At higher temperatures, it decreases slowly. On the other hand, as shown by X2, the amount of deposit
It decreases as the temperature rises from 0 ° C, and sharply decreases when the temperature exceeds 80 ° C. When the temperature further increases to about 90 ° C., the precipitate is completely eliminated. This is because the vapor pressure increases as the temperature of the dielectric 13 increases, and precipitates are scattered by the vapor pressure.

From these findings, it is clear that setting the scattering temperature from 90 ° C. to 200 ° C. prevents deposition of precipitates. However, when the temperature of the ozonizer 10 exceeds 140 ° C., the generation rate of ozone is reduced, and there is a possibility that a problem such as a fire may occur. Therefore, in this embodiment, the temperature of the ozonizer 10 is set to a value not exceeding 140 ° C., more preferably, from 90 ° C. to 120 ° C., and the dielectric 13 is heated in a region where the ozone generation ratio Rt is high. I have.

According to the ozonizer 10 having the above-described structure, when the ozone deodorizer A is stopped, as in the conventional structure, crystals of the malodorous component precipitate on the surface of the dielectric 13 and the crystals deliquesce. When the ozone deodorizer A is actuated and the application to both electrodes 11 and 12 is started, the heater 13 fixes the dielectric 13.
Is heated to the scattering temperature, whereby the precipitate is scattered from the dielectric 13, whereby the salt attached to the surface of the dielectric 13 can be removed. Therefore, according to the present embodiment, there is a remarkable effect that the adverse effect of the discharge effect due to the precipitate can be prevented, the discharge in the dielectric 13 can be stabilized, and the ozone generation rate can be prevented from lowering.

In particular, in this embodiment, when the ozone deodorizer A is stopped, the deliquescent salt can be scattered without fail. Therefore, by continuing the operation of the deodorizing operation system for a predetermined time,
There is an advantage that the amount of generated ozone can be stabilized. Further, since the scattering temperature is 90 ° C. or higher, there is an advantage that moisture condensed on the surface of the dielectric 13 is also scattered by the vapor pressure and the raw material air is dried, so that good ozone generation performance can be exhibited.

In this embodiment, the power supply circuit 16 delays the stop of the power supply to the heating wire 14a after a predetermined time has elapsed after the application to both electrodes 11 and 12 is completed. After the application of the salt, the salt to be attached to the surface of the dielectric 13 is diffused, and the deliquescence of the salt can be prevented. Next, in this embodiment,
In order to maintain the temperature of the ozonizer 10 in the above range,
As shown in FIG. 1, the following configuration is adopted.

First, the temperature of the ozonizer 10 is set to the room C
Easily affected by the wind speed of the air introduced from the air. That is, when air is introduced into the casing A1 by the fan A6, the air flow directly hits the ozonizer 10, so that the ozonizer 10 is cooled. For this reason, when the processing air flow rate of the ozone deodorizer A is changed, the ozonizer 1 is cooled by the cooling effect of the air flow.
0 may not be maintained at the desired temperature.

Therefore, in this embodiment, a hood 20 is provided upstream of the ozonizer 10 and the heater 14.
The hood 20 is, for example, an engineering plastic or the like.
It is formed of a resin or the like having heat resistance to the extent that it is not affected by heat from the heater 14. According to the configuration of this embodiment, the air flow is directly caused by the hood 20 by the ozonizer 1.
0 can be prevented from contacting the fan A6.
Irrespective of the number of rotations, the cooling effect of the airflow on the ozonizer 10 can be reduced as much as possible. Therefore, the ozonizer 10 can be maintained at a desired temperature, which has a remarkable effect that a decrease in the ozone generation rate can be prevented.

Next, the temperature of the ozonizer 10 is set to
Easily influenced by the temperature of the air itself introduced from the air. That is, for example, in a winter season or a cold region, even if the air volume is the same, the cooling effect by the air flow is further promoted, so that the ozonizer 10 may not be able to be maintained at a desired temperature. Therefore, in the present embodiment, an indoor temperature sensor SN for detecting the temperature of the indoor C is provided, and the control device 17 can control the rotation speed of the fan A6 based on the detection signal of the indoor temperature sensor SN. That is, when the temperature of the room C falls below the predetermined temperature, the fan A6
The number of revolutions is forcibly reduced. As a result, the wind speed of the air flow also decreases, so that the cooling effect of the ozonizer 10 due to the air flow can be reduced.

According to the configuration of this embodiment, the control device 17
By controlling the rotation speed of the fan A6, the cooling effect of the airflow on the ozonizer 10 can be reduced as much as possible regardless of the temperature of the room C. Therefore, the ozonizer 10 can be maintained at a desired temperature, which has a remarkable effect that a decrease in the ozone generation rate can be prevented.

When the temperature of the room C is low, the number of revolutions of the fan A6 is reduced, so that there is an advantage that it is possible to suppress discomfort due to cold ventilation from the circulation side. Further, the temperature sensor SN may not only detect the temperature of the air in the room C, but may also detect the temperature of the ozonizer 10 itself. Next, another embodiment shown in FIG. 3 will be described.

Ozone deodorizer 1A in the embodiment of FIG.
Is different from the embodiment of FIG. 1 in that a control device 117 is used instead of the control device 17. The control device 117 obtains, from the change in the voltage applied to the ozonizer 10,
It has a function of detecting abnormal discharge of the ozonizer 10 due to salt adhesion or deliquescence, and operates the heater 14 by operating the heater 14 when abnormal discharge is detected.
The salt adhering to 0 is removed. As a method of operating the heater 14, a cleaning switch is provided in the operation unit of the ozone deodorizer A, and when a discharge abnormality occurs, a discharge abnormality detection lamp provided in the operation unit is turned on to notify a user and perform the cleaning. Preferably, the switch is operated. As another method, the heater 14 is automatically controlled by the control device 117.
Voltage application to the dielectric 13 is started from 90 ° C. to 120 ° C.
It may be made to heat to ° C.

In any case, the effect of removing the salt from the dielectric 13 can be obtained in the same manner as in the embodiment of FIG. 1, and the operation of the heater 14 can be performed only when there is a discharge abnormality that requires the removal of the salt. Therefore, there is an advantage that the power consumption of the heater 14 can be reduced. Next, FIG.
An example will be described.

The ozone deodorizer 2A of the embodiment of FIG. 4 differs from the embodiment of FIG. 1 in that a controller 217 is employed instead of the controller 17 and the sensor SN is omitted. . The control device 217 has a function of intermittently stopping the rotation of the fan A6 for a predetermined time (for example, 5 min / 8 h) while the deodorizing operation system is operating.

When the control device 217 stops the rotation of the fan A6, the cooling effect by the air flow does not work.
The surface temperature of the dielectric 13 rises, for example, to about 140 ° C. As a result, the salt adhering to the surface of the dielectric 13 is diffused, and deliquescence of the salt can be prevented. Therefore, the salt is removed from the dielectric 13 similarly to the embodiment of FIG.
This can prevent adverse effects due to deposits of offensive odor components.

Further, in the embodiment shown in FIG.
Since the surface temperature of the dielectric 13 can be increased when the fan 0 or the fan A6 is stopped, the cooling effect of the airflow on the ozonizer 10 can be reduced as much as possible regardless of the temperature of the room C. In addition, there is an advantage that the ability to remove salts can be improved. Next, still another embodiment shown in FIG. 5 will be described.

The ozone deodorizer 3A of the embodiment shown in FIG. 5 includes an ozonizer 310 having a dielectric 13 sandwiched between an induction electrode 11 and a discharge electrode 12, and a fan A6 for introducing air in a room C into the ozonizer 310. Deodorizing actuation system S containing
This embodiment differs from the embodiment shown in FIG. 1 in that the YS is configured and that the control device 317 is employed instead of the control device 17 and the sensor SN is omitted.

The control device 317 includes a deodorizing operation system SYS.
After the end of the operation, the heater 14 is operated for a predetermined time to diffuse the salt attached to the surface of the dielectric 13.
The surface temperature of the dielectric 13 heated by the heater 14 is
In the case of the present embodiment, the temperature is set to about 140 ° C. This is because the heater 14 operates after the operation of the deodorizing operation system SYS is completed, so that it is not necessary to consider a decrease in the amount of ozone generated due to the heat of the ozonizer 10, and the set temperature is accordingly reduced as shown in FIG.
6, the air diffusion time decreases linearly with increasing temperature at around 140 ° C., but as the temperature rises above 140 ° C., as shown in FIG. For this reason, the ratio of time to be reduced is reduced, and the merit is reduced.

When the temperature of the dielectric 13 is 140 ° C., the time for which the heater 14 operates is preferably about 15 minutes. Therefore, in this embodiment, the deodorizing operation system S
After the previous stoppage of YS, the time during which the heater 14 was operated is integrated by the control device 317, and the operating time of the heater 14 is approximately 1/90 (≒ 15 min / 24).
h).

In this embodiment, the salt can be prevented from adhering before the salt deliquesces, so that the salt deliquescent can be prevented. Therefore, as in the embodiment of FIG. 1, the salt is removed from the dielectric 13, thereby preventing the adverse effect of the odorous component precipitate. Further, in the embodiment of FIG. 5, since the heater 14 operates after the operation of the ozonizer 10 and the fan A6 is completed, there is an advantage that the power consumption of the heater 14 can be further reduced. That is, for example, when the resistance value of the heating wire 14a of the heater 14 is 120Ω and the surface temperature is maintained at 90 ° C. during the operation of the deodorizing operation system of the dielectric 13 when the voltage is 26V AC, power W = voltage V ² ÷ resistance value R = 26 × 26 ÷ 120 = 5.6 (W). Therefore, the deodorizing operation system SYS is set to 2
After four hours of operation, 5.6 x 24 = 134.4 watt-hours / day.

On the other hand, in the embodiment of FIG. 5, since the voltage application time of the heater 14 per day can be reduced to about 15 minutes, the heating wire 14 having the same resistance value (120Ω) can be used.
Even if the power consumption W is set to 7.5 W by applying a voltage of 30 V AC to the heater 14 having a, the power consumption becomes 7.5 × 0.25 = 2 watt-hours / day. Significant (134.4-2 =
132.4 watt-hours / day).

Next, still another embodiment shown in FIG. 7 will be described. FIG. 7 shows an embodiment in which the dielectric 13 of the ozonizer 10 is covered with the holder 30. The holder 30 in this embodiment includes a base portion 31 disposed on the lower surface side of the ozonizer 10 and a base end side of the dielectric 13 (an end portion on which wirings of the circuits 15 and 16 are provided).
And a pair of tip-side holding portions 33 and 34 that cover the tip side of the dielectric 13.

The holding portions 33 and 34 are formed integrally with the base portion 31 with the discharge electrode 12 of the ozonizer 10 substantially opened. Here, the maximum temperature when the ozonizer 10 is heated is about 120 for the above-described reason.
° C, the temperature of the holder 30 is
There is a possibility that it will be lower than that. Therefore, even when the heater (not shown) is heating the ozonizer 10, the deposit S of the malodorous component easily adheres to the holder 30.

In this embodiment, however, the holding section 3
2, 33, and 34 hold the ozonizer 10 in a state where the discharge electrode 12 of the ozonizer 10 is substantially opened, so that the deposition of the precipitate S can be prevented as much as possible. In order to confirm such effects,
The inventor of the present application measured the attached amount (mg / day) of the precipitate (ammonium salt) S using the holder 30 of the above example.

As a result, the measurement condition was that the temperature in the room C = 2.
6.6 ° C., humidity = 59.0% RH, malodorous component (ammonia) concentration = 1.25 ppm, operation time = 33 hours, temperature of dielectric substance 13 = 95.8 ° C., the amount of deposited precipitate = 0.0 mg was obtained. On the other hand, under the same measurement conditions as described above, as a result of measurement using the conventional holder 135 shown in FIG.
0.5 mg.

As described above, according to the embodiment of FIG. 7, even in the holder type ozonizer 10, the adverse effect of the discharge effect due to the precipitates S is prevented, the discharge in the dielectric 13 is stabilized, and the ozone generation rate is reduced. This has a remarkable effect of preventing a decrease in the temperature. The present invention,
The present invention is not limited to the embodiment described above.
In the embodiment, the control device 317 may be set so that the dielectric 13 is heated even during the operation of the deodorizing operation system.

As is apparent from the above-described embodiment,
The term “removal of salt” in the present invention may be a concept meaning that the salt adhering to or adhering to the surface of the dielectric 13 is diffused. May be a concept that means to scatter. As the control means, as exemplified in each embodiment, each control device 1 of the ozone deodorizer A, 1A, 2A, 3A
7, 117, 217 and 317 may be used, and other electrical components and the like may be used.

It goes without saying that various design changes can be made without departing from the scope of the present invention.

[0053]

As described above, according to the ozonizer according to the first aspect of the present invention, the adverse effect of the discharge effect due to the salt is prevented, the discharge in the dielectric is stabilized, and the deterioration of the ozone generation performance is prevented. It has a remarkable effect that it can be performed. In particular, according to the ozonizer according to the second aspect of the present invention, the deliquescent salt can be scattered to the dielectric without fail, so that the application of voltage to both electrodes is continued for a predetermined time to stabilize the amount of generated ozone. There is an advantage that it can be done.

Further, according to the ozonizer according to the third aspect of the present invention, after the application to both electrodes is completed, the salt which is to be attached to the surface of the dielectric is diffused, and the deliquification of the salt is prevented beforehand. Thus, the adhesion of salt can be more reliably prevented. Further, according to the ozonizer of the fourth aspect of the present invention, since the heating means operates only at the time of a discharge abnormality requiring the removal of salt, there is an advantage that the power consumption of the heating means can be reduced.

Further, according to the ozonizer according to the fifth aspect of the present invention, since the holder holds the dielectric in a state where the discharge electrode is almost completely opened, it is possible to prevent the salt from adhering to the holder. In addition, it is possible to reliably prevent the discharge electrode from being covered with the salt. Therefore, even when the dielectric is held by the holder, the above effects can be obtained.

Next, according to the ozone deodorizer according to the sixth aspect of the present invention, the air flow can be prevented from coming into direct contact with the ozonizer by the hood, so that the air flow to the ozonizer is independent of the rotation speed of the fan. Can be reduced as much as possible, and the above effect can be obtained. Also,
According to the ozone deodorizer according to claim 7 of the present invention, the control means controls the number of revolutions of the fan, so that the cooling effect of the airflow to the ozonizer is reduced as much as possible regardless of the indoor temperature. The effect can be achieved.

Further, according to the ozone deodorizer according to the eighth aspect of the present invention, since the control means intermittently controls the stop of the fan, the surface temperature of the dielectric can be forcibly increased. In addition to the effect of claim 7 , the heating means
The ability to remove salts by heating can be improved. Furthermore, according to the ozone deodorizer according to claim 9 of the present invention,
Since the heating means is operated during the deodorization operation system stops, the heating means
There is an advantage that the power consumption of the heating means can be further reduced in removing the salt by heating.
