589200 五、發明說明（1) [發明所屬之技術領域] 本發明是有關於一種脫臭裝置，適用於分解並脫臭 空氣中所含的臭氣成份及有害物質等。 [先前技術] 近年來，隨著屋外空氣及噪音等的環境污染的平常 化，住宅之高氣密化的進展，對於居住空間内的空氣品 質改善的期望變得很高。在空氣品質中，對於香煙的煙 臭及病人的看護環境等的代謝臭氧的降低，及由住宅建 材產生的V0C(揮發性有機物）所代表的有害氣體成份之去 除的需求變得特別大。 對於這些期望，習知係採用以活性碳為代表的吸著 臭分子的脫臭方式，或是以其他的藥劑和惡臭成份反應 而變更臭氣的特性的方法等。 在習知的技術中，利用吸著劑脫臭或是把有害氣體 成份除去者係受到吸著量的限制，長期使用時，脫臭過 濾器的交換便為不可或缺。且，脫臭過濾器在壽命期間 中的壽命末期時，仍會有把已吸著的臭分子再放出而產 生臭氣的可能。 另一方面，以其他的藥劑成份和臭氣成份反應而變 更臭氣特質的方法。因為藥劑成份會消耗，吸收藥劑需 卜2個月更換1次的頻率，相當麻煩，而且藥劑成份放至 環境的放出量則會受到室内溫度的控制，當室溫高則藥 劑的放出量便會增加，而對於脫臭效的放出量及藥劑成 份的壽命的關連控制也相當困難。589200 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a deodorizing device suitable for decomposing and deodorizing odorous components and harmful substances contained in the air. [Prior Art] In recent years, with the normalization of environmental pollution such as outdoor air and noise, and the progress of high airtightness of houses, expectations for improvement in air quality in living spaces have become high. In terms of air quality, there is a particularly large demand for reduction in the smoke odor of cigarettes and reduction of metabolic ozone in the patient's care environment, as well as removal of harmful gas components represented by VOCs (volatile organic compounds) produced by residential building materials. In response to these expectations, conventionally, a deodorization method using adsorbed odor molecules typified by activated carbon, or a method of changing the characteristics of odor by reacting other medicines with odor components, etc. have been conventionally used. In the conventional technology, those who use a sorbent to deodorize or remove harmful gas components are restricted by the amount of sorption. When used for a long time, the exchange of the deodorizing filter is indispensable. In addition, at the end of the life of the deodorizing filter, there is still a possibility that odorous molecules that have been adsorbed are released again to generate an odor. On the other hand, a method for changing the odor properties by reacting other pharmaceutical ingredients with odor components. Because the ingredients of the medicine will be consumed, the frequency of absorbing the medicine needs to be changed once every two months, which is quite troublesome, and the amount of medicine released into the environment will be controlled by the indoor temperature. When the room temperature is high, the amount of medicine released will be Increase, and it is also quite difficult to control the amount of deodorizing effect and the life of the pharmaceutical ingredient.

Description of the invention (2) In addition, in order to remove harmful gas components such as formic acid (formaldehyde), a catalyst reaction with a high redox potential is required, from ozone oxidation to intermediate decomposition that has not been completely decomposed yet. It is very difficult to completely harmless the generation stage. Therefore, although it is possible to irradiate ultraviolet rays to a photocatalyst represented by titanium oxide to generate active oxygen, and then use its strong oxidizing power to completely decompose harmful gas components, as an ultraviolet light source, a mercury-containing fluorescent lamp in a tube is required. The environmental impact at the time of disposal is not good. [Summary of the Invention] [Problems to be Solved by the Invention] In order to solve these problems, a high-voltage discharge is used to generate ozone or ultraviolet rays, and then a photocatalyst module activated by the ultraviolet rays is used, which is harmful to the odor components contained in the air and harmful. Substances are decomposed, and ozone generated by the high-voltage discharge device is decomposed by an ozone decomposer. This deodorizing device system is excellent in controlling deodorizing performance, completely decomposing harmful gas, and environmental load when disposing of the device. However, because high-voltage discharge is used, a discharge corresponding to the discharge frequency is generated. sound. In addition, depending on the conditions of the high-voltage discharge, there may be problems such as noise and video reception such as shadow television. Regarding discharge noise, as described by the applicant of the present invention in Japanese Patent Laying-Open No. 2000-1-5 9 4 7 7, although it is effective to make the discharge frequency outside the human audible range, but, In the discharge frequency below the audible range of 50 pps or less, the amount of ultraviolet or ozone obtained from the discharge decreases proportionally with the frequency, so the deodorizing performance is impaired.
1 1020pif.ptd 第7頁 589200 五、發明說明（3) 而，若使其放電的頻率為可聽域以上時，雖無放電 音及脫臭性能上的問題，然而，依放電頻率比例產生的 臭氧則會因其場合而產生需要量以上，因而造成臭氧分 解裝置的壽命減短的問題，更，當在可聽域以上的 2 0 k p p s以上進行放電時，控制回路的發熱量會大增，因 而需要各別的冷卻裝置，此為缺點。 為了解決上述的課題，本發明提出一種脫臭裝置， 在人類的可聽域以上的頻率放電，以解決脫臭性能及放 電音的問題，且又可減少臭氧的發生量以延長臭氧分解 裝置的壽命，且對於控制回路不需冷卻裝置。 [解決課題的手段] 為解決上述課題，本發明的脫臭裝置，包括：產生 臭氧及紫外線的一高壓放電裝置、利用此高壓放電裝置 產生的紫外線，進行被活化的空氣中所含臭氧成份及有 害物質等的分解作用之一光觸媒模組，以及分解從高壓 放電裝置所產生臭氧之一臭氧分解裝置。其中高壓放電 裝置、光觸媒模組及臭氧分解裝置係配置於一送風路通 内，且高壓放電裝置的放電頻率為可聽域以上。 以此結構，不會產生放電音的問題，且可使臭氧的 發生量減少以延長臭氧分解裝置的壽命，又可抑制回路 部的發熱量，因而可不需專用的冷卻裝置，故可降低成 本0 在上述的發明中，高壓放電裝置的放電頻率為 2 0 k p p s以上，且放電的開-關間隔為一一定的時間間隔，1 1020pif.ptd Page 7 589200 V. Description of the invention (3) If the discharge frequency is above the audible range, there will be no problems with discharge sound and deodorization performance. Ozone will cause more than the required amount due to the occasion, which will cause the problem of shortening the life of the ozone decomposition device. Furthermore, when the discharge is performed above 20 kpps above the audible range, the heat generation of the control circuit will increase greatly. Therefore, a separate cooling device is required, which is a disadvantage. In order to solve the above-mentioned problems, the present invention proposes a deodorizing device that discharges at frequencies above the human audible range to solve the problems of deodorizing performance and discharge sound, and can reduce the amount of ozone generated to extend the ozone decomposing device. Life, and no cooling device is required for the control circuit. [Means for Solving the Problems] In order to solve the above problems, the deodorizing device of the present invention includes a high-voltage discharge device that generates ozone and ultraviolet rays, and uses ultraviolet rays generated by the high-pressure discharge device to perform ozone components contained in the activated air and A photocatalyst module which is one of the decomposition functions of harmful substances and the like, and an ozone decomposition device which decomposes ozone generated from a high voltage discharge device. The high-voltage discharge device, photocatalyst module and ozone decomposition device are arranged in a supply air path, and the discharge frequency of the high-voltage discharge device is above the audible range. With this structure, the problem of discharge sound is not generated, and the amount of ozone generated can be reduced to prolong the life of the ozone decomposition device, and the heat generation of the circuit part can be suppressed. Therefore, a dedicated cooling device is not needed, so the cost can be reduced. In the above invention, the discharge frequency of the high-voltage discharge device is 20 kpps or more, and the on-off interval of the discharge is a certain time interval.

Description of the invention (4) And the intermittent running frequency is below 50Hz or above 20kHz. Because the discharge frequency is outside the range of the audible range, no noise will be generated because the frequency of the gap operation is in the audible range. In the above invention, the intermittent operation control of the high-voltage discharge device is changed based on the response of an odor sensor. When there is less odor, it can reduce the amount of odorous oxygen and the heat generated in the circuit. In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is described below in detail with the accompanying drawings as follows: [Embodiment] Hereinafter, according to the drawings An embodiment of the present invention will be described. Fig. 1 shows a longitudinal cross-sectional view of the deodorizing device 1 of the present invention, and a fan 4 is arranged in a cooling air duct of a refrigerator and an air path of an air conditioner. In the formed air path 3, a photocatalyst module 5 is provided on the upper side of the wind, and a decomposition catalyst filter (fi 11 er) 10 is disposed between the photocatalyst group 5 and the air-sending fan 4. The photocatalyst module 5 is a photocatalyst which is coated with a photocatalyst material typified by titanium oxide on the surface of a substrate made of porous ceramics such as Iro and Shi Xiica (si 1 ica), and is dried or sintered to fix the photocatalyst. Two filters 6 and 7 are arranged next to each other. Between this photocatalyst filter, a discharge electrode 8 formed by a thin plate #etching to form a mesh shape is set upright, and the two photocatalyst filters described above On the upwind and downwind sides of the air path 3 of 6 and 7, counter electrodes 9 similar to the discharge electrodes 8 are arranged, respectively. In addition, the photocatalyst filter of the photocatalyst module 5 is not necessarily limited to

Description of the invention (5) Two pieces are arranged next to each other, such as the deodorizer installed in the air-conditioning path from the refrigerator freezer to the fruit and vegetable room. When the odor component or ethylene plankton is less, In this case, the counter electrode 9 and the discharge electrode 8 may be provided before and after a single photocatalyst filter. 11 is a power supply circuit. A high-voltage generating transformer 1 2 is used to apply a positive pulse-shaped DC high voltage between the aforementioned discharge electrode 8 and each pair of poles 9. The mesh size of the discharge electrode 8 is larger than the mesh size of the counter electrode 9. With this structure, the discharge electrode 8 and the counter electrode 9 have a function of a discharge means for generating ultraviolet rays, so as to generate ultraviolet rays having a wavelength of 380 nm or less due to the discharge between the electrodes. In addition, when the discharge electrode 8 and the counter electrode 9 are discharged, because the ultraviolet rays and ozone are generated, the photocatalyst module 5 has a function of completely decomposing harmful gas components with active oxygen generated by ultraviolet rays, and also has a function of an ozone generating means. . The ozone-absorbing ozonolysis catalyst filter 10, which absorbs a predetermined distance from the photocatalyst module 5 to the downwind side, is composed of a honeycomb-shaped sintered body mainly composed of manganese dioxide. The operation of the deodorizing device 1 configured as described above is as follows. That is, the power is supplied to the power supply circuit 1 1 and the blower fan 4 is driven. When a voltage is applied between the discharge electrode 8 and the counter electrode 9, ultraviolet rays caused by the discharge are generated between the electrodes.

Description of the invention (6) The combination of gas components and organic compounds is decomposed and deodorized with no odor or low odor. Furthermore, the bacterial cell membrane of the bacteria is embrittled for antibacterial purposes, and the proliferation of microorganisms on the surfaces of the photocatalyst filters 6, 7 is inhibited by oxidative decomposition, so as to decompose and remove the dirt on the surface of the deodorizing device 1 and the airway wall. Compared with the comparative example of one embodiment of the present invention based on the above-mentioned structure, in the above-mentioned operation, a peak voltage of 4 k V (kilovolts) is applied to the human between the discharge electrode 8 and the counter electrode 9. A voltage of 20 kpps (kilopulses / second) at a discharge frequency above the audible range for continuous operation. In this case, the relationship between the discharge frequency with a peak voltage of 4 kV and the contour of noise is shown in Fig. 2. When the discharge frequency is 2 Okpps, the discharge sound is above the human audible range. Because it is in the range where the sound is not felt by the human, the device's noise value is 1 7. 6 db, and there is no near dark noise ( dark noise) (15.4db). However, when the discharged ozone is 1.1 ppm as the operating environment standard and exceeds 0.5 p pin or more, the resistance surface temperature on the power circuit 11 supplying a high voltage may also become extremely high at 150 degrees Celsius. Generally, when the impedance surface temperature exceeds 70 to 80 degrees Celsius, the circuit life becomes extremely short. In the case of this comparative example, a cooling device is required to maintain the circuit life, which will be reviewed in the following examples. [Example] As the deodorizing device of the present invention, as in FIG. 1, when the discharge electrode 8 and the counter electrode 9 are applied with a peak voltage of 4 kV and a voltage of 20 kpps, the discharge is turned on ( 0 N) time is 0 · 0 1 second, and off (0 FF) time is 0. 0 9

The operating frequency of on-off times per second during this gap operation is 50 1 Z or less or 20 k 2 ζ or more outside the audible range. Even if the discharge frequency is outside the audible range, the frequency of the gap operation is still In the audible range, the noise problem should not occur. As a result, the noise value was 17.6 db, which was not the same as the previous comparative example, but its ozone emission was 0.9 ppm, which was much lower than the operating environment standard. The high-voltage circuit was 11 The surface temperature of the impedance is 38 degrees Celsius, which is a degree that does not require cooling on the circuit. [Embodiment 2] The basic structure is the same as that of Embodiment 1, and a power supply circuit 11 for supplying a local voltage is provided on the air path 3. The noise value at this time was 17.6 dB, and the ozone emission was 0.9 ppm, which is the same as in Example 1, and the impedance surface temperature on the high-voltage circuit 11 was 32 degrees Celsius, which was lower than that in Example 1. And the extent of the problem. Generally, a heating device such as a cooling fan needs to be provided in the heating part such as the impedance on the high-voltage circuit 1; however, in the operation of the deodorizing device of this embodiment, the fan is always used in the wind. A high-voltage circuit 1 1 is set in a part of the cross-sectional area of this air path 3, and the air flow is generated in the road.

In contrast, at the B position on the downwind side, the air cleaned by the photocatalytic oxidation and decomposition can be used for cooling, and the high-voltage transformer 12 can be protected from odorous substances. [Example 4] Although not shown in the figure, when an odorous substance is contacted, an odor sensor such as a hot wire semiconductor sensor using tin oxide is used as a sensing material system for detecting the contact by using a change in impedance. Set in the deodorizing device, the discharge frequency is 20kpps, the OFF time of the discharge is 0.05 seconds, and the ON time is 0. 0 1 ~ 0 according to the signal from the odor sensor. 〇9 seconds proportionally change, thereby forming a circuit. When the voice level at this time is as low as 16.8 to 17.8db, the amount of ozone generated can be 0.13 to 0 · 23ρριm, which is 0.5ppm or less below the operating environment standard, and it becomes a degree without practical problems.
