Description
本發明是有關於一種臭氧裝置,且特別是有關於一種可自動調整臭氧排放濃度的裝置及其操作方法。The present invention relates to an ozone device, and more particularly to an apparatus for automatically adjusting an ozone emission concentration and a method of operating the same.
產生臭氧的方法可概分為三類:高壓放電、紫外光光解、電解。因為電解法需要用到液體,在環境淨化的應用上限制較多。高壓放電方式是坊間臭氧機所使用的主流技術,但若使用空氣為原料,或是氧氣純度不高,高壓放電過程中會產生氮氧化物。這些氮氧化物不僅無助於空氣淨化,更是影響人體健康的空氣污染物。紫外光光解法係使用波長在200 nm以下的紫外光照射空氣,因為此類短波長的紫外光具有很高的能量,可以將空氣中的氧氣和水氣解離,形成臭氧以及其他具有活性的物質(active agents,以下稱之為淨化因子);但此波段的能量卻不足以將氮氣解離,故不會產生氮氧化物,在環境淨化的應用上,紫外光光解的方法相對具有優勢。The methods for generating ozone can be broadly classified into three types: high pressure discharge, ultraviolet photolysis, and electrolysis. Because electrolysis requires the use of liquids, there are more restrictions on the application of environmental purification. The high-pressure discharge method is the mainstream technology used in the ozone machine. However, if air is used as the raw material, or the purity of oxygen is not high, nitrogen oxides will be generated during high-voltage discharge. These nitrogen oxides not only do not contribute to air purification, but also air pollutants that affect human health. Ultraviolet photolysis uses ultraviolet light with a wavelength below 200 nm to illuminate the air, because such short-wavelength ultraviolet light has a high energy, which can dissociate oxygen and water in the air to form ozone and other active substances. (active agents, hereinafter referred to as purification factors); but the energy of this band is not enough to dissociate nitrogen, so it does not produce nitrogen oxides. In the application of environmental purification, the method of ultraviolet photolysis is relatively advantageous.
短波長(200 nm以下)的紫外光能量可以將空氣中的水氣和氧氣離子化,進而產生臭氧(O 3)、負氧離子(O 2 -)、氫氧自由基(OH ‧)和雙氧水(H 2O 2)等具氧化活性的淨化因子。這些產生的淨化因子可以與空氣中的污染物(如甲醛、甲苯、氨氣…)或表面污染物(如細菌、黴菌、三手菸…)反應,進而去除污染物,達到淨化效能。 Short-wavelength (under 200 nm) UV energy can ionize water and oxygen in the air, which produces ozone (O 3 ), negative oxygen ions (O 2 - ), hydroxyl radicals (OH ‧ ) and hydrogen peroxide. An oxidation-active purification factor such as (H 2 O 2 ). These produced purification factors can react with pollutants in the air (such as formaldehyde, toluene, ammonia...) or surface pollutants (such as bacteria, mold, three-handed smoke...) to remove contaminants and achieve purification efficiency.
要產生波長在200 nm以下紫外光的方法很多,可以是熱陰極燈管、冷陰極燈管、準分子燈、發光二極體或是其他紫外光源,此類波長的燈管必須使用高純度的石英管,以避免燈管吸收紫外光或是造成玻璃變質,而影響紫外光的穿透率。There are many ways to generate ultraviolet light with a wavelength below 200 nm, which can be hot cathode lamps, cold cathode lamps, excimer lamps, light-emitting diodes or other ultraviolet light sources. Lamps of such wavelengths must be of high purity. Quartz tube to avoid the absorption of ultraviolet light or deterioration of the glass, which affects the transmittance of ultraviolet light.
不管是以哪種方式產生臭氧,在環境淨化的應用上,都必須面對室內臭氧濃度控制的問題,特別是有人在室內活動時,臭氧濃度必須低於法規的要求。但是坊間會產生臭氧的淨化裝置大多沒有這樣的設計和控制機制,高濃度的臭氧對使用者的健康可能會有潛在的威脅。Regardless of the way in which ozone is produced, in the application of environmental purification, it is necessary to face the problem of indoor ozone concentration control. Especially when people are indoors, the ozone concentration must be lower than the requirements of the regulations. However, most of the ozone purification devices in the workshop do not have such design and control mechanisms. High concentrations of ozone may pose a potential threat to the health of users.
為解決臭氧濃度過高的問題,在不少專利文獻中都提出了各自的解決方案,如中國專利公開號CN107543284A、CN107051150A、CN107015578A等。這些既有專利中雖使用了臭氧感測器去量測臭氧濃度並做為控制臭氧產生裝置的依據,但控制的方式都僅僅採用開啟或關閉,這類控制方式容易造成臭氧濃度的劇烈變化,不僅無法有效控制臭氧濃度,更可能因為頻繁的開關,而減損設備的使用壽命。In order to solve the problem of excessive ozone concentration, various solutions have been proposed in many patent documents, such as Chinese Patent Publication No. CN107543284A, CN107051150A, CN107015578A, and the like. Although these existing patents use ozone sensors to measure the ozone concentration and serve as the basis for controlling the ozone generating device, the control methods are only used to turn on or off. Such control methods are likely to cause drastic changes in ozone concentration. Not only is it impossible to effectively control the ozone concentration, but it is also likely to detract from the life of the equipment due to frequent switching.
部分專利雖然也設置了臭氧感測器,但卻是安裝在出風口,重點在控制出風口的臭氧濃度,如中國專利公開號CN205386402U。但即使出風口的臭氧濃度達到標準,若使用空間太小,也可能造成室內臭氧濃度過高,不代表室內的臭氧濃度在安全有效的範圍之內。Although some patents also set up an ozone sensor, it is installed at the air outlet, focusing on controlling the ozone concentration of the air outlet, such as Chinese Patent Publication No. CN205386402U. However, even if the ozone concentration of the air outlet reaches the standard, if the space used is too small, the indoor ozone concentration may be too high, which does not mean that the indoor ozone concentration is within a safe and effective range.
本發明提供一種可自動調整臭氧排放濃度的裝置及其操作方法,其可以維持空氣中的臭氧濃度在有效且安全的範圍內。The present invention provides an apparatus for automatically adjusting an ozone emission concentration and an operation method thereof, which can maintain an ozone concentration in the air in an effective and safe range.

為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。The above described features and advantages of the invention will be apparent from the following description.

In addition, wherever possible, the elements and/ Elements/components/steps that use the same reference numbers or use the same terms in different embodiments may refer to the related description.
下述諸實施例將說明一種可自動調整臭氧排放濃度的裝置。透過感測空氣中的臭氧濃度,此裝置可以對應控制光生臭氧模組與送風模組二者中的一者或多者,以便將空氣中的臭氧濃度維持在有效且安全的範圍內。下述諸實施例將以光解反應作為光生臭氧模組的應用範例,並假設光生臭氧模組所產生的光為紫外光。The following examples will illustrate an apparatus for automatically adjusting the ozone emission concentration. By sensing the concentration of ozone in the air, the device can correspondingly control one or more of the photo-ozone module and the air supply module to maintain the ozone concentration in the air within an effective and safe range. The following examples will use photolysis as an application example of a photo-generated ozone module, and assume that the light generated by the photo-generated ozone module is ultraviolet light.
光生臭氧模組以紫外光光解的方式產生臭氧,可避免高壓放電方式會產生氮氧化物的副作用。光生臭氧模組產生的光解反應在高濕氣的環境下,因為水氣容易被紫外光解離成淨化因子,所以反而可提高淨化效能。其他吸附型淨化器會因濕氣佔據吸附的孔洞,而快速降低效能。習知的臭氧裝置無法隨室內臭氧濃度的變化,而及時調整輸出功率,或僅僅透過開/關的方式來調整臭氧排放濃度,亦即限定了臭氧產率或容易造成臭氧濃度大幅波動。若是室內空間太小或太大,就容易發生室內臭氧濃度過高或過低的現象。現在的法規和國家標準對室內的臭氧濃度和淨化裝置的出口臭氧濃度都有嚴格的規定。以台灣為例,室內臭氧濃度要低於0.06 ppm,而中國大陸對室內臭氧濃度要求須低於0.16 mg/m 3(GB/T 18883-2002,約0.08 ppm)。另外,對淨化裝置出風口的臭氧濃度要求須低於0.10 mg/m 3(GB 21551.3-2010,約0.05 ppm)。若該淨化裝置無法有效控制室內環境累積的臭氧濃度和裝置出口臭氧濃度,就不能在市面上販售。 The photo-generated ozone module generates ozone by means of ultraviolet photolysis, which can avoid the side effects of nitrogen oxides generated by high-voltage discharge. The photolysis reaction produced by the photo-generated ozone module is in a high-humidity environment, because the water vapor is easily dissociated by the ultraviolet light into a purification factor, so that the purification efficiency can be improved. Other adsorption purifiers quickly reduce efficiency due to moisture occupying the adsorbed pores. The conventional ozone device cannot adjust the output power in time according to the change of the indoor ozone concentration, or adjust the ozone emission concentration only by the on/off method, that is, the ozone yield is limited or the ozone concentration is likely to fluctuate greatly. If the indoor space is too small or too large, the indoor ozone concentration is likely to be too high or too low. Current regulations and national standards have strict regulations on the indoor ozone concentration and the outlet ozone concentration of the purification unit. In Taiwan, for example, the indoor ozone concentration is lower than 0.06 ppm, while the indoor ozone concentration requirement in mainland China must be less than 0.16 mg/m 3 (GB/T 18883-2002, about 0.08 ppm). In addition, the ozone concentration at the outlet of the purification unit must be less than 0.10 mg/m 3 (GB 21551.3-2010, approximately 0.05 ppm). If the purification device cannot effectively control the ozone concentration accumulated in the indoor environment and the ozone concentration at the outlet of the device, it cannot be sold in the market.

Please refer to FIG. 1 and FIG. 2 . In step S210, the air supply module 140 can create a wind flow in the airflow path of the device 100, and the photo-ozone module 110 can generate ozone in a manner of ultraviolet light photolysis in the air flow path of the device 100. This embodiment does not limit the implementation of the photo-generated ozone module 110. For example, the photo-generated ozone module 110 may be an ultraviolet light source (for example, an ultraviolet hot cathode lamp, a cold cathode lamp, an excimer lamp, a light-emitting diode, or another ultraviolet light source capable of photolysis). Photogenic ozone module. This embodiment does not limit the implementation of the air supply module 140. For example, the air supply module 140 can include a conventional fan and circuit module or other electromechanical device that can create a wind flow.
於步驟S220中,臭氧感測器130可以感測空氣中的臭氧濃度(此為環境中累積的臭氧濃度)。本實施例並不限制臭氧感測器130的實現方式。舉例來說,臭氧感測器130可以是習知的感測器或是可以感測臭氧的其他感測器。本實施例所述裝置100可搭配各種類型的臭氧感測器,例如半導體式臭氧感測器、電化學式臭氧感測器、紫外光吸收法臭氧感測器或其他具再現性的感測器。臭氧感測器130所測得的濃度訊號可以透過有線(或無線)的方式被傳送至控制電路120。依照設計需求,在一些實施例中,臭氧感測器130可以被配置在裝置100內的風流路徑的入風段。舉例來說,臭氧感測器130可以被配置在裝置100的入風口附近,以便感測裝置100所處場域的空氣中的臭氧濃度。在另一些實施例中,臭氧感測器130可以被配置在裝置100外部,以便感測裝置100所處場域(例如房間)的空氣中的臭氧濃度。舉例來說,臭氧感測器130與裝置100都被配置在同一個場域中,但是臭氧感測器130的位置可以不同於裝置100的位置。In step S220, the ozone sensor 130 may sense the concentration of ozone in the air (this is the concentration of ozone accumulated in the environment). This embodiment does not limit the implementation of the ozone sensor 130. For example, ozone sensor 130 can be a conventional sensor or other sensor that can sense ozone. The device 100 of the present embodiment can be combined with various types of ozone sensors, such as a semiconductor ozone sensor, an electrochemical ozone sensor, an ultraviolet light absorption ozone sensor, or other reproducible sensors. The concentration signal measured by the ozone sensor 130 can be transmitted to the control circuit 120 by wire (or wireless). In accordance with design requirements, in some embodiments, the ozone sensor 130 can be configured in an air intake section of the wind flow path within the apparatus 100. For example, the ozone sensor 130 can be disposed adjacent the air inlet of the device 100 to sense the concentration of ozone in the air in the field in which the device 100 is located. In other embodiments, the ozone sensor 130 can be configured external to the device 100 to sense the concentration of ozone in the air in the field (eg, the room) in which the device 100 is located. For example, both ozone sensor 130 and device 100 are disposed in the same field, but the location of ozone sensor 130 can be different than the location of device 100.
於步驟S230中,控制電路120可以依照所述臭氧濃度來對應控制光生臭氧模組110,以調整臭氧產率。舉例來說,在控制電路120判斷後,控制電路120可以調整光生臭氧模組110中的紫外光源的輸出功率,以改變光生臭氧模組110釋放出的臭氧量。當空氣中的臭氧濃度過低時,控制電路120可以調升紫外光源的輸出功率,以便加大臭氧產率。當空氣中的臭氧濃度過高時,控制電路120可以調降紫外光源的輸出功率,以便減小臭氧產率。因此,裝置100可確保空氣中的臭氧濃度在安全範圍以內,並維持最佳且安全的環境淨化效能。In step S230, the control circuit 120 can correspondingly control the photo-ozone module 110 according to the ozone concentration to adjust the ozone yield. For example, after the control circuit 120 determines, the control circuit 120 can adjust the output power of the ultraviolet light source in the photo-generated ozone module 110 to change the amount of ozone released by the photo-generated ozone module 110. When the concentration of ozone in the air is too low, the control circuit 120 can increase the output power of the ultraviolet light source to increase the ozone yield. When the concentration of ozone in the air is too high, the control circuit 120 can reduce the output power of the ultraviolet light source to reduce the ozone yield. Thus, device 100 ensures that the concentration of ozone in the air is within safe limits and maintains optimal and safe environmental purification performance.

For example, after the control circuit 120 determines, the control circuit 120 can adjust the rotational speed of the blade in the air supply module 140 to change the ozone concentration in the wind flow path. When the ozone concentration is too low, the control circuit 120 can reduce the rotational speed of the blade to increase the concentration of ozone in the wind flow path. When the ozone concentration is too high, the control circuit 120 can increase the rotational speed of the blade to reduce the concentration of ozone in the wind flow path. Thus, the device 100 ensures that the emitted ozone concentration is within safe limits and maintains an optimal and safe environmental purification performance.

圖8是依照本發明的一實施例說明圖1所示光生臭氧模組110當使用熱陰極燈管112為紫外光源的電路方塊示意圖。圖8所示電源10可以供電給光生臭氧模組110。電源10可以是任何電源電路/元件。舉例來說,電源10可以是習知電力供應電路或是其他電源電路/元件。再舉例來說,電源10可以是提供小直流電壓(小於50伏特)的電源適配器、市電整流器、車載直流電源供應器或是其他直流電源電路。FIG. 8 is a block diagram showing the circuit of the photo-generated ozone module 110 of FIG. 1 when the hot cathode lamp 112 is used as an ultraviolet light source according to an embodiment of the invention. The power source 10 shown in FIG. 8 can be powered to the photo-ozone module 110. Power source 10 can be any power circuit/component. For example, power source 10 can be a conventional power supply circuit or other power supply circuit/component. By way of further example, power source 10 can be a power adapter that provides a small DC voltage (less than 50 volts), a mains rectifier, a vehicle DC power supply, or other DC power circuit.
於圖8所示實施例中,光生臭氧模組110包括可調式光源驅動器111(例如可調式安定器)以及熱陰極燈管112(紫外光源)。電源10可以供電給可調式光源驅動器111。可調式光源驅動器111耦接至熱陰極燈管112。可調式光源驅動器111可以提供電能EE,以驅動熱陰極燈管112來產生光能EL。In the embodiment shown in FIG. 8, the photo-generated ozone module 110 includes an adjustable light source driver 111 (eg, an adjustable ballast) and a hot cathode lamp tube 112 (ultraviolet light source). The power source 10 can be powered to the adjustable light source driver 111. The adjustable light source driver 111 is coupled to the hot cathode lamp tube 112. The adjustable light source driver 111 can provide electrical energy EE to drive the hot cathode fluorescent tube 112 to generate light energy EL.
熱陰極燈管112被配置在裝置100內的風流路徑中。熱陰極燈管112可以產生光能EL,以便在所述風流路徑中產生臭氧。依照設計需求,熱陰極燈管112可以包括紫外線燈管或是其他類型燈管。短波長紫外光源除可應用於殺菌外,其產生光解反應的作用也可應用於室內環境品質的改善。依照設計需求,在一些應用例中,所述紫外光源所輻射出的光線波長主要集中在UVC範圍(波長為100-280 nm)。當輸出功率可以依操作條件或應用場景而改變時,可以擴大使用範圍、有效降低操作費用。The hot cathode lamp tube 112 is disposed in a wind flow path within the device 100. The hot cathode lamp 112 can generate light energy EL to generate ozone in the wind flow path. According to design requirements, the hot cathode lamp 112 may include an ultraviolet lamp or other type of lamp. In addition to being used for sterilization, the short-wavelength ultraviolet light source can also be used for the improvement of indoor environmental quality. According to design requirements, in some applications, the wavelength of light radiated by the ultraviolet light source is mainly concentrated in the UVC range (wavelength is 100-280 nm). When the output power can be changed according to operating conditions or application scenarios, the scope of use can be expanded, and the operating cost can be effectively reduced.
當紫外光源所輻射出的光線的波長範圍低於200 nm時,不僅具有殺菌的效能,還能驅動光解反應。光解反應可以分為直接光解反應(direct photolysis)與間接光解反應(indirect photolysis)兩部分。直接光解反應是藉由短波長(波長小於200 nm)的紫外光的能量直接破壞污染物的分子鍵結。間接光解反應則是透過短波長的紫外光的能量將空氣中的水氣和氧氣離子化後,產生如臭氧、雙氧水、氫氧自由基、超氧離子…等對污染物具有氧化還原能力的淨化因子,再由此類淨化因子和污染物反應,達到淨化空氣與表面污染物的目的。When the wavelength of light radiated by the ultraviolet light source is less than 200 nm, it not only has the effect of sterilization, but also drives the photolysis reaction. Photolysis reactions can be divided into two parts: direct photolysis and indirect photolysis. The direct photolysis reaction directly destroys the molecular bonds of contaminants by the energy of ultraviolet light of a short wavelength (wavelength less than 200 nm). The indirect photolysis reaction is to ionize the water vapor and oxygen in the air through the energy of the short-wavelength ultraviolet light to generate redox capable of reducing pollutants such as ozone, hydrogen peroxide, hydroxyl radicals, superoxide ions, and the like. The purification factor is then reacted by such purification factors and pollutants to purify the air and surface pollutants.
直接光解反應係透過波長小於200 nm的紫外光來驅動。依據浦朗克-愛因斯坦方程式(Planck-Einstein equation,式(1))與光波長及頻率的關係式(式(2)),可以獲得式(3)。在式(1)、式(2)與式(3)中, E為光線的能量( eV或k J/mol), h為浦朗克常數, 為光線的頻率( s -1), C為光速, 為光波長(nm)。浦朗克常數為4.1357 * 10 -15( eV ×s)或6.63 * 10 -34( J ×s),其中1 eV= 1.6 * 10 -19 J 。光速為3 x 10 8 m/s 。由式(3)算出185 nm波長的紫外光具有6.7 eV的能量(相當於646 k J/ mol)。 The direct photolysis reaction is driven by ultraviolet light having a wavelength of less than 200 nm. According to the relationship between the Planck-Einstein equation (Formula (1)) and the wavelength and frequency of light (Equation (2)), the formula (3) can be obtained. In equations (1), (2), and (3), E is the energy of light ( eV or k J/mol ), and h is the Planck constant. For the frequency of light ( s -1 ), C is the speed of light, It is the wavelength of light (nm). The Planck constant is 4.1357 * 10 -15 ( eV × s ) or 6.63 * 10 -34 ( J × s ), where 1 eV = 1.6 * 10 -19 J . The speed of light is 3 x 10 8 m/s . The ultraviolet light of 185 nm wavelength calculated from equation (3) has an energy of 6.7 eV (equivalent to 646 k J / mol ).

當分子間的鍵能小於紫外光所放射的能量(646 k J/ mol)時,分子鍵結就可能被破壞而崩解。反之,當分子鍵能大於紫外光的能量時,分子鍵結就不容易被破壞。依此推論,舉凡下述表1的分子鍵都有可能被光解反應破壞。表1涵括了絕大部分的室內污染物或是異臭味。 When the bond energy between molecules is less than the energy emitted by ultraviolet light (646 k J / mol ), the molecular bond may be destroyed and disintegrated. Conversely, when the molecular bond energy is greater than the energy of the ultraviolet light, the molecular bond is not easily destroyed. Accordingly, it is inferred that the molecular bonds of Table 1 below may be destroyed by photolysis. Table 1 covers most of the indoor pollutants or odors.

空氣中的氮氣因為N≡N的鍵能高達940 kJ/mol,此波長(185 nm)的紫外光不足以分解氮氣而產生氮氧化物。氮氧化物一般是在高溫(燃燒)或高電場(如臭氧產生器的電暈放電)才可能產生。Nitrogen in the air has a bond energy of up to 940 kJ/mol due to N≡N, and ultraviolet light at this wavelength (185 nm) is insufficient to decompose nitrogen to produce nitrogen oxides. Nitrogen oxides are generally produced at high temperatures (combustion) or high electric fields (such as corona discharge from ozone generators).
間接光解反應也是透過波長小於200 nm的紫外光來驅動。參照下述式(4)至式(10)所示反應式,紫外光的強大能量可將空氣中的氧氣和水氣加以離子化,以產生臭氧、水合氫離子、氫氧自由基、過氧化氫、超氧離子(或稱負氧離子,O 2 -)等淨化因子。此類淨化因子都具有很強的氧化/還原能力,特別是氫氧自由基,其強氧化力會迅速與空氣中的污染物反應。由於此類淨化因子的壽命小於1 ms,等於是一出反應室就反應耗盡或是還原為水,故對人體造成傷害的機會極低。 The indirect photolysis reaction is also driven by ultraviolet light having a wavelength of less than 200 nm. Referring to the reaction formulas of the following formulas (4) to (10), the powerful energy of ultraviolet light can ionize oxygen and water in the air to generate ozone, hydronium ions, hydroxyl radicals, peroxidation. Purification factors such as hydrogen and superoxide ions (or negative oxygen ions, O 2 - ). These purification factors have strong oxidation/reduction ability, especially hydroxyl radicals, and their strong oxidizing power will quickly react with pollutants in the air. Since the life of such a purification factor is less than 1 ms, it is equivalent to a reaction in the reaction chamber that is exhausted or reduced to water, so the chance of causing harm to the human body is extremely low.

上述淨化因子可對環境中的異味和附著在表面的細菌、病毒、黴菌和三手菸等污染物,起到良好的除菌去味作用,以達到環境淨化的目的。理論上,淨化因子濃度越高,除菌去味效果越好。但實際應用上,必須考量在環境中生活的人的安全性,過高的淨化因子濃度有可能造成健康上的風險。這些淨化因子的產生量與光生臭氧模組的輸出功率息息相關。藉由調控光生臭氧模組的輸出功率,可以調控淨化因子的產生量。The above-mentioned purification factor can play a good sterilization and deodorizing effect on the odor in the environment and the bacteria, viruses, molds and three-handed smoke adhering to the surface, so as to achieve the purpose of environmental purification. In theory, the higher the concentration of the purification factor, the better the sterilization and deodorization effect. However, in practical applications, the safety of people living in the environment must be considered. Too high a concentration of purification factors may cause health risks. The amount of these purification factors is closely related to the output power of the photo-ozone module. By regulating the output power of the photo-ozone module, the amount of purification factor can be regulated.
可調式光源驅動器111可以對熱陰極燈管112的輸出功率進行調整,使出口的臭氧濃度可以控制在安全範圍內。濃度在安全範圍內的臭氧不僅具有除菌去味的環境淨化功效,且不會危害人體健康。由於熱陰極燈管112是負電阻的特性,其啟動電流(電壓)與工作電流(電壓)相差甚多。當要調整其工作功率時,熱陰極燈管112的工作電流與頻率需要被調整於容許範圍內。本實施例所示可調式光源驅動器111運用可程式化控制器(例如微處理器等)和內建脈波寬度調變功能來偵測熱陰極燈管112之特性,並據以調整熱陰極燈管112的工作電流與頻率。因此,本實施例所示可調式光源驅動器111可點亮燈管,並在一定的控制範圍內,對輸出功率加以調整。The adjustable light source driver 111 can adjust the output power of the hot cathode lamp 112 so that the ozone concentration of the outlet can be controlled within a safe range. Ozone with a concentration within a safe range not only has the environmental purification effect of sterilization and deodorization, but also does not endanger human health. Since the hot cathode lamp 112 is characterized by a negative resistance, its starting current (voltage) is much different from the operating current (voltage). When the operating power is to be adjusted, the operating current and frequency of the hot cathode lamp 112 need to be adjusted within an allowable range. The adjustable light source driver 111 of the present embodiment uses a programmable controller (such as a microprocessor, etc.) and a built-in pulse width modulation function to detect the characteristics of the hot cathode lamp 112 and adjust the hot cathode lamp accordingly. The operating current and frequency of the tube 112. Therefore, the adjustable light source driver 111 shown in this embodiment can illuminate the lamp tube and adjust the output power within a certain control range.
請參照圖8,在啟動熱陰極燈管112時,可調式光源驅動器111先升高管電壓以便導通熱陰極燈管112的兩端電極,進而激發氣體放電以產生光能(例如紫外光)EL。當熱陰極燈管112被導通後,可調式光源驅動器111即時降壓以免燒毀燈管,並且可調式光源驅動器111以高頻諧振方式來驅動熱陰極燈管112以維持穩定的光能EL。Referring to FIG. 8, when the hot cathode lamp 112 is activated, the adjustable light source driver 111 first raises the tube voltage to turn on the electrodes at both ends of the hot cathode tube 112, thereby exciting the gas discharge to generate light energy (for example, ultraviolet light) EL. . When the hot cathode lamp 112 is turned on, the adjustable light source driver 111 is stepped down to avoid burning the lamp, and the adjustable light source driver 111 drives the hot cathode lamp 112 in a high frequency resonance manner to maintain stable light energy EL.
控制電路120耦接至可調式光源驅動器111。控制電路120可以從熱陰極燈管112獲得相關於光能EL的回饋資訊。控制電路120依據所述回饋資訊去控制可調式光源驅動器111,以調整可調式光源驅動器111所輸出的電能EE的頻率與電流。亦即,控制電路120可以響應於熱陰極燈管112的光能EL來動態調整熱陰極燈管112的驅動電能EE的頻率與電流。因此,可調式光源驅動器111可以回饋調整熱陰極燈管112的輸出功率。The control circuit 120 is coupled to the adjustable light source driver 111. The control circuit 120 can obtain feedback information related to the light energy EL from the hot cathode lamp 112. The control circuit 120 controls the adjustable light source driver 111 according to the feedback information to adjust the frequency and current of the electric energy EE output by the adjustable light source driver 111. That is, the control circuit 120 can dynamically adjust the frequency and current of the driving electric energy EE of the hot cathode lamp tube 112 in response to the light energy EL of the hot cathode lamp tube 112. Therefore, the adjustable light source driver 111 can feedback the output power of the hot cathode lamp 112.
圖8所示可調式光源驅動器111包括諧振電路111a以及逆變器(inverter)電路111b。本實施例並不限制諧振電路111a的實施方式。舉例來說,諧振電路111a可以是習知的諧振電路或是其他諧振電路/元件。在一些實施例中,諧振電路111a可以是串聯諧振串並聯負載(Series resonant series-parallel load, SRSPL)電路。逆變器電路111b耦接至諧振電路111a。逆變器電路111b可以提供電能EE以驅動熱陰極燈管112。舉例來說,逆變器電路111b負責提升電壓,以提供工作電壓給熱陰極燈管112。The adjustable light source driver 111 shown in FIG. 8 includes a resonance circuit 111a and an inverter circuit 111b. This embodiment does not limit the embodiment of the resonant circuit 111a. For example, the resonant circuit 111a can be a conventional resonant circuit or other resonant circuit/component. In some embodiments, the resonant circuit 111a can be a Series resonant series-parallel load (SRSPL) circuit. The inverter circuit 111b is coupled to the resonance circuit 111a. The inverter circuit 111b can provide electrical energy EE to drive the hot cathode lamp tube 112. For example, the inverter circuit 111b is responsible for boosting the voltage to provide an operating voltage to the hot cathode lamp tube 112.
回饋電路121負責偵測並傳回負載(熱陰極燈管112)的功耗給控制電路120。詳而言之,回饋電路121耦接至熱陰極燈管112,以獲得相關於光能EL的回饋資訊FB。舉例來說,回饋資訊FB可以包括負載(熱陰極燈管112)的目前功耗。回饋電路121將回饋資訊FB輸出給控制電路120。於圖8所示實施例中,臭氧感測器130將臭氧感測訊號提供給控制電路120。The feedback circuit 121 is responsible for detecting and returning the power consumption of the load (the hot cathode lamp 112) to the control circuit 120. In detail, the feedback circuit 121 is coupled to the hot cathode lamp 112 to obtain feedback information FB related to the light energy EL. For example, the feedback information FB can include the current power consumption of the load (hot cathode lamp 112). The feedback circuit 121 outputs the feedback information FB to the control circuit 120.

For example, the control circuit 120 adjusts one or more of the at least one inductance value and the at least one capacitance value inside the resonant circuit 111a according to the feedback information FB and the ozone sensing signal to adjust the frequency and current of the electrical energy EE. In other embodiments, the control circuit 120 adjusts the air volume of the air supply module 140 according to the feedback information FB and the ozone sensing signal. In other embodiments, the control circuit 120 adjusts the air volume of the air supply module 140 according to the feedback information FB and the ozone sensing signal, and simultaneously controls the resonant circuit 111a to adjust the frequency and current of the electrical energy EE.
換句話說,控制電路120以動態感應方式即時得知熱陰極燈管112的目前功耗。控制電路120可以響應於熱陰極燈管112的目前功耗(或光能EL)來動態調整熱陰極燈管112的驅動電能EE的頻率與電流。因此,控制電路120與光生臭氧模組110可以回饋調整熱陰極燈管112的輸出功率。In other words, the control circuit 120 instantly knows the current power consumption of the hot cathode lamp 112 in a dynamic sensing manner. The control circuit 120 can dynamically adjust the frequency and current of the drive power EE of the hot cathode lamp 112 in response to the current power consumption (or light energy EL) of the hot cathode lamp 112. Therefore, the control circuit 120 and the photo-generated ozone module 110 can feedback the output power of the hot cathode lamp 112.
依照設計需求,在一些實施例中,控制電路120還可以從使用者介面電路(未繪示)接收功率調節指令(臭氧濃度調整指令)。控制電路120可以響應於所述功率調節指令來動態調整熱陰極燈管112的驅動電能EE的頻率與電流,以便調整熱陰極燈管112的輸出功率。舉例來說,當接受到所述功率調節指令時,控制電路120可以運算所需調整之功率後,去調整諧振電路111a的頻率和/或逆變器電路111b的輸出電流,以改變熱陰極燈管112的輸出功率。控制電路120還可以依照臭氧感測器130的臭氧感測訊號(臭氧濃度)對應控制可調式光源驅動器111,以動態調整熱陰極燈管112的驅動電能EE的頻率與電流,進而調整熱陰極燈管112的輸出功率。舉例來說,控制電路120還可以依照臭氧感測器130的臭氧感測訊號對應地控制諧振電路111a的頻率和/或逆變器電路111b的輸出電流,進而調整熱陰極燈管112的輸出功率。In some embodiments, the control circuit 120 can also receive a power adjustment command (ozone concentration adjustment command) from a user interface circuit (not shown). Control circuit 120 can dynamically adjust the frequency and current of drive power EE of hot cathode lamp 112 in response to the power adjustment command to adjust the output power of hot cathode lamp 112. For example, when receiving the power adjustment command, the control circuit 120 can calculate the frequency of the required adjustment power, and then adjust the frequency of the resonance circuit 111a and/or the output current of the inverter circuit 111b to change the hot cathode lamp. The output power of the tube 112. The control circuit 120 can also control the adjustable light source driver 111 according to the ozone sensing signal (ozone concentration) of the ozone sensor 130 to dynamically adjust the frequency and current of the driving power EE of the hot cathode lamp 112, thereby adjusting the hot cathode lamp. The output power of the tube 112. For example, the control circuit 120 can also control the frequency of the resonant circuit 111a and/or the output current of the inverter circuit 111b according to the ozone sensing signal of the ozone sensor 130, thereby adjusting the output power of the hot cathode lamp 112. .
在一些實施例中,控制電路120還可以依據使用者介面電路(未繪示)的風量指令去控制送風模組140的轉速。控制電路120還可以依據送風模組140的轉速來對應控制可調式光源驅動器111,以調整電能EE的輸出功率(例如頻率與電流)。當送風模組140的轉速增加(亦即風量增加)時,控制電路120可以調整電能EE的輸出功率(例如頻率與電流),以增加熱陰極燈管112的輸出功率。當送風模組140的轉速減少(亦即風量減少)時,控制電路120可以調整電能EE的輸出功率(例如頻率與電流),以減少熱陰極燈管112的輸出功率。因此,在一些應用範例中,控制電路120可以即時調整紫外線燈管(紫外光源112)的臭氧產率,維持裝置出口臭氧濃度在有效且安全的範圍內,不會因風量改變造成出風口的臭氧濃度過高或過低。In some embodiments, the control circuit 120 can also control the rotational speed of the air supply module 140 according to the air volume command of the user interface circuit (not shown). The control circuit 120 can also correspondingly control the adjustable light source driver 111 according to the rotational speed of the air supply module 140 to adjust the output power (eg, frequency and current) of the electrical energy EE. When the rotational speed of the air supply module 140 increases (ie, the air volume increases), the control circuit 120 can adjust the output power (eg, frequency and current) of the electrical energy EE to increase the output power of the hot cathode fluorescent tube 112. When the rotational speed of the air supply module 140 is reduced (ie, the air volume is reduced), the control circuit 120 can adjust the output power (eg, frequency and current) of the electrical energy EE to reduce the output power of the hot cathode fluorescent tube 112. Therefore, in some application examples, the control circuit 120 can instantly adjust the ozone yield of the ultraviolet lamp (ultraviolet light source 112), maintain the ozone concentration of the device outlet in an effective and safe range, and do not cause the ozone of the air outlet due to the change of the air volume. The concentration is too high or too low.
