Description
本發明有關一種複合式水活氧洗淨功能設備，尤指一種利用電壓控制臭氧供應量，以達到穩定殺菌功能之洗淨設備。The invention relates to a composite water active oxygen cleaning function equipment, in particular to a cleaning equipment that uses a voltage to control the supply of ozone to achieve a stable sterilization function.
目前有相當多的洗淨設備乃是強調透過超音波來增加洗淨或去污之效果，雖號稱可完全去除髒污且快速，但大多數洗淨設備之超音波乃為單一頻段，使用者無法依照洗淨之物品種類來調整適當對應之頻段，僅就單頻之超音波可達到之洗淨效果有限，對於黏著力較強之汙垢或細菌可能無法完全有效的去除。At present, there are quite a lot of cleaning equipment that emphasizes the effect of cleaning or decontamination through ultrasound. Although it is claimed to completely remove dirt and fast, the ultrasonic wave of most cleaning equipment is a single frequency band. Users The appropriate frequency band cannot be adjusted according to the type of items to be cleaned, and only a single frequency ultrasonic wave can achieve a limited cleaning effect. It may not be able to completely remove dirt or bacteria with strong adhesion.
臭氧(O3 )，又稱為超氧或活氧，是氧氣（O₂）的同素異形體，是一種強氧化劑，其氧化能力高於氯和二氧化氯，能破壞分解細菌的細胞壁，達到殺菌效果。但是臭氧的穩定性很差，水質、溫度以及pH值皆是影響臭氧穩定性的重要因素，在常温下非常不稳定。Ozone (O 3 ), also known as superoxide or active oxygen, is an allotrope of oxygen (O₂). It is a strong oxidant. Its oxidizing power is higher than that of chlorine and chlorine dioxide. It can destroy the cell wall of decomposing bacteria and reach Bactericidal effect. However, the stability of ozone is very poor. Water quality, temperature, and pH are all important factors affecting ozone stability, which is very unstable at room temperature.
市售有具臭氧殺菌功能之洗淨機，係在一個容器中填充臭氧，進行容器中蔬果的清洗。然，使用時，洗淨機中的臭氧在開啟後即不停的供應臭氧，因此水中含有高濃度的臭氧，過多的臭氧會散溢到空氣中，而在空氣不流通的地方，或是長期吸入過多臭氧，有引發肺部疾病之虞。A commercially available washing machine with ozone sterilization function is filled with ozone in a container for cleaning fruits and vegetables in the container. However, during use, the ozone in the washing machine is constantly supplying ozone after it is turned on. Therefore, the water contains a high concentration of ozone. Excessive ozone will spill into the air, and in places where air does not circulate, or for a long time Excessive ozone inhalation may cause lung diseases.
有機磷是農藥中普遍存在的化學成份，服用過多有機磷將會抑制人體內的乙醯膽鹼脢，導致神經末稍的乙醯膽鹼無法被代謝分解掉，而造成乙醯膽鹼過剩而不斷的刺激神經末稍，引起中樞神經系統中毒。Organophosphorus is a common chemical component in pesticides. Taking too much organophosphorus will inhibit the acetylcholine 醯 in the human body, which will cause the nerve terminal acetylcholine cannot be metabolized and depleted, resulting in excess acetylcholine. Constantly stimulate nerve endings, causing central nervous system poisoning.

實施例二Example two
本實施例係將待洗物用本發明之設備清洗後，分別進行農藥活性檢測以及菌數檢測。In this embodiment, after the object to be washed is cleaned by the device of the present invention, pesticide activity detection and bacteria count detection are performed respectively.
針對農藥活性檢測，本實施例採用「膽鹼酯酶生化法」，因有機磷劑與氨基甲酸鹽劑農藥進入生物體後，會跟膽鹼酯酶的活性形成不可逆的結合，並抑制其活性、延緩生物體內水解速率、干擾傳遞造成疲倦、噁心、昏迷甚至死亡等症狀，而生化法即依此測定酶活性遭抑制的程度來判斷農藥殘留含量。For the detection of pesticide activity, the "cholinesterase biochemical method" is used in this embodiment. After the organophosphorus and carbamate pesticides enter the organism, they will form an irreversible combination with the activity of cholinesterase and inhibit it. Activity, delay the rate of hydrolysis in the body, interfere with the transmission and cause symptoms such as fatigue, nausea, coma and even death, and the biochemical method is used to determine the level of inhibited enzyme activity to determine the content of pesticide residues.
請參閱第4圖所示，膽鹼酯酶的活性在待洗物透過本發明之設備清洗後，活性有明顯下降；亦顯示，本發明之設備對於有機磷的去除有良好的功效。Please refer to FIG. 4. After the cholinesterase activity is washed through the device of the present invention, the activity of the cholinesterase has a significant decrease; it also shows that the device of the present invention has a good effect on the removal of organic phosphorus.
菌數檢測部分，將待洗物分別經過本發明之設備以超音波、臭氧以及超音波加臭氧，三種方式進行清洗(即滅菌)，再將待洗物經過系列稀釋使菌落在培養基上生長數目介於25-250 colony forming unit (CFU)之間，測定總菌數；其中待洗物為液體；該超音波頻率為45K。The bacteria count detection part is to wash the object to be washed with ultrasonic, ozone and ultrasonic plus ozone in the device of the present invention in three ways to clean (ie, sterilize), and then serially dilute the object to be washed to grow the colonies on the medium. It is between 25-250 colony forming unit (CFU), and the total number of bacteria is measured; the material to be washed is liquid; the ultrasonic frequency is 45K.
請參閱第5圖所示，因臭氧具有破壞、分解細菌細胞壁的功能，因此有使用臭氧的待洗物，其菌數都比原液少，而超音波與臭氧一起使用情況下，殺菌數幾乎可達100 %，即顯示本發明之設備具有良好的殺菌效果。Please refer to Figure 5. Because ozone has the function of destroying and decomposing bacterial cell walls, there are objects to be washed that use ozone. The number of bacteria is less than that of the original solution. When ultrasound is used with ozone, the number of bacteria is almost sterilizable. When it reaches 100%, it shows that the device of the present invention has good sterilization effect.
請再參閱第5圖所示，本發明之設備可依據待洗物選擇不同洗淨方式，也可多種洗淨方式一同使用，以達到加倍殺菌的功能。Please refer to FIG. 5 again, the device of the present invention may select different washing methods according to the items to be washed, or multiple washing methods may be used together to achieve the function of double sterilization.
