Description
本發明係提供一種蔬果清洗之水質感測裝置及感測方法,尤指一種藉由顏色感測器、濁度感測器及紫外光感測器所組複合式感測組合單元,用以依序分別偵測蔬果汁液、蔬果表面附著泥沙及蔬果表面附著農藥,因為本發明一次僅開啟一個感測器做單一項目感測且不斷清洗直到該項目低於預設數值,開閉已執行完畢之感測器後才開啟下一個未執行之感測器,以使感測器判斷上不受其他感測器干擾而更加精確,更進一步達到即省清潔時所耗費水、電力及時間之目的。 The present invention provides a water quality sensing device and sensing method for washing vegetables and fruits, especially a composite sensing combination unit composed of a color sensor, a turbidity sensor and an ultraviolet sensor, which is used to The sequence of detection of vegetable juice liquid, sediment attached to the surface of vegetables and fruits, and pesticide attached to the surface of vegetables and fruits, because the present invention only turns on one sensor at a time to sense a single item and continuously cleans until the item is lower than the preset value, and the opening and closing have been completed. After the sensor, the next unexecuted sensor is turned on, so that the sensor is not interfered by other sensors and is more accurate in its judgment, and further achieves the purpose of saving water, electricity and time during cleaning.
按,近年食安問題逐漸受到重視,消費者越來越在意蔬果中是否有農藥殘留,然而農藥區分為系統性與非系統農藥,佔少部分的系統性農藥無法藉由清洗來去除,而大部分的非系統性農藥經過一預設時間的自來水清洗後可以自蔬果表面去除,因此現代人基於常識都會利用人工方式以清水清洗蔬果,而更加講究者會利用蔬果清洗機來進行更加細部的清洗,以達到更佳的清洗效果。 According to the press, in recent years, food safety issues have gradually attracted attention, and consumers have become more and more concerned about whether there are pesticide residues in fruits and vegetables. However, pesticides are divided into systemic and non-systemic pesticides. Some non-systemic pesticides can be removed from the surface of fruits and vegetables after being washed with tap water for a preset time. Therefore, based on common sense, modern people will use artificial methods to wash fruits and vegetables with water, while those who are more particular will use vegetable and fruit washing machines for more detailed cleaning. , in order to achieve better cleaning effect.
習知國內外專利及相關文獻指出部分熱門慣用農藥具有與紫外光產生吸收反應,藉以檢驗出蔬果表面農藥殘留量,即如習知中國專利CN 105181667A提出一種利用紫外線所構成螢光探測器來進行蔬果表面 農藥殘留檢測後,然後進行清洗作業。但僅有單一螢光探測器所感測的數值不夠精確,因該螢光感測器會受到蔬果上的泥沙、碎屑、汁液等非農藥物質所干擾感測數值,而由錯誤感測數值將誤導螢光感測器判斷仍有農藥殘留,造成使用者或是蔬果清洗裝置需要持續清洗,造成過多的水、電及時間上之浪費。 Known domestic and foreign patents and related documents point out that some popular and commonly used pesticides have an absorption reaction with ultraviolet light, so as to detect the pesticide residues on the surface of vegetables and fruits. Vegetable and fruit surface After detection of pesticide residues, the cleaning operation is carried out. However, the value sensed by only a single fluorescent detector is not accurate enough, because the fluorescent sensor will be disturbed by non-pesticide substances such as sand, debris, juice and other non-pesticide substances on vegetables and fruits, and the wrongly sensed value will be detected. It will mislead the fluorescent sensor to judge that there are still pesticide residues, causing the user or the vegetable and fruit cleaning device to need to continue cleaning, resulting in excessive waste of water, electricity and time.

將會拉長,雖然平價的預設電子裝置1之感測泥沙及農藥的殘留功能及效果與高階預設電子裝置1無異,但其消耗水及電力卻隨之增加為其缺點。而平價預設電子裝置1與高階預設電子裝置1皆為本發明可實施態樣,故一併提出做一保護。
