Description
本發明係與瓦斯裝置有關，更詳而言之是指一種缺氧保護裝置。The present invention relates to a gas plant, and more particularly to an oxygen deficiency protection device.
使用瓦斯燃燒器具(如熱水器、瓦斯爐、壁爐等)最常發生的意外就是一氧化碳中毒，而一氧化碳中毒是指在不通風的環境下，因氧氣不足而導致瓦斯燃燒不完全，進而而產生有毒氣體一氧化碳的堆積，人們在不知情的情況下將一氧化碳吸入體內的意外事故。The most common accidents that use gas-fired appliances (such as water heaters, gas stoves, fireplaces, etc.) are carbon monoxide poisoning. Carbon monoxide poisoning refers to incomplete combustion of gas due to insufficient oxygen in a non-ventilated environment, which in turn produces toxic gases. The accumulation of carbon monoxide, people accidentally inhaled carbon monoxide into the body accidents.
瓦斯燃燒器具在使用時，瓦斯與氧氣充分混合是有效燃燒的基本要件，在完全燃燒時，其所含之碳、氫元素皆會變成二氧化碳和水，而在不完全燃燒時，則會產生有毒之一氧化碳，尤其在氧氣不足的情況下此不完全燃燒情形更加嚴重，而於冬季時，因為氣溫低，人們在怕冷的前題下，通常都會將窗戶緊閉造成室內空氣不流通，很容易就會產生氧氣不足、一氧化碳堆積的情形，進而造成一氧化碳中毒。When the gas burner is used, the gas and oxygen are fully mixed, which is the basic requirement for effective combustion. When it is completely burned, the carbon and hydrogen contained in it will become carbon dioxide and water, and when it is not completely burned, it will be toxic. One of the carbon oxides, especially in the case of insufficient oxygen, this incomplete combustion situation is more serious. In the winter, because of the low temperature, people often close the window and cause the indoor air to circulate, which is easy. Oxygen deficiency and carbon monoxide accumulation can occur, which in turn causes carbon monoxide poisoning.
另外，氧氣為人們維續生命不可或缺的要素之一，空氣的組成主要由氮氣78.09%、氧氣20.95%、氬氣0.93%、二氧化碳0.03%及其他微量氣體所組成，一般來說，室內空氣氧氣濃度最好穩定維持在20.5%以上，方足以供應人呼吸及燃燒所需，而依行政院勞工委員會訂定之缺氧預防規則，則必須保持 作業場所空氣中氧氣濃度在18%以上，才可確定人員安全無虞。In addition, oxygen is one of the indispensable elements of people's life. The composition of air is mainly composed of nitrogen gas 78.09%, oxygen 20.95%, argon gas 0.93%, carbon dioxide 0.03% and other trace gases. Generally, indoor air The oxygen concentration should be stable and maintained at more than 20.5%, which is sufficient for people to breathe and burn. The rules for prevention of hypoxia according to the Labor Committee of the Executive Yuan must be maintained. The oxygen concentration in the workplace air is above 18% to ensure the safety of personnel.
而為達缺氧保護之目的，遂有業者研發一種用於瓦斯燃燒器具之缺氧保護裝置，請參閱圖1，習用之缺氧保護裝置包含有一熱電耦50以及一瓦斯閥60，該熱電耦50設於一瓦斯燃燒裝置40附近，用以依據該瓦斯燃燒裝置40燃燒瓦斯時產生之熱量輸出一熱電勢；該瓦斯閥60具有一線圈62、一磁鐵64、一彈簧66以及一閥門68，該線圈62與該熱電耦50電性連接，用以接收該熱電勢以產生一磁吸力吸引該磁鐵66，藉以壓縮該彈簧64來開啟該閥門68，進而達到供予瓦斯之目的。當該瓦斯燃燒裝置40周圍之氧氣濃度下降時，其產生之熱量亦隨之降低，將導致該熱電耦50產生之熱電勢下降。藉此，當缺氧導致該熱電勢下降至一定程度時，該線圈62產生之磁吸力將小於該彈簧66之彈力，使得原先受壓縮之該彈簧66伸展而推動該磁鐵64移動，而關閉該閥門68，進而達到阻卻瓦斯供應之目的。For the purpose of protection against hypoxia, a manufacturer has developed an oxygen-deficient protection device for gas burners. Referring to Figure 1, the conventional anoxic protection device includes a thermocouple 50 and a gas valve 60. The thermocouple The gas valve 50 has a coil 62, a magnet 64, a spring 66 and a valve 68. The gas valve 60 is disposed adjacent to the first gas burner 40 for outputting a heat potential according to the heat generated when the gas burner 40 burns gas. The coil 62 is electrically connected to the thermocouple 50 for receiving the thermoelectric force to generate a magnetic attraction force to attract the magnet 66, thereby compressing the spring 64 to open the valve 68, thereby achieving the purpose of supplying gas. When the oxygen concentration around the gas combustion device 40 decreases, the amount of heat generated therefrom also decreases, which causes the thermoelectric potential generated by the thermocouple 50 to drop. Thereby, when the oxygen deficiency causes the thermoelectric potential to drop to a certain extent, the magnetic force generated by the coil 62 will be less than the spring force of the spring 66, so that the originally compressed spring 66 extends to push the magnet 64 to move, and closes the Valve 68, in turn, blocks the supply of gas.
然而，習用之缺氧保護裝置是透過磁力與彈力之機構設計來偵測周圍之氧氣濃度是否過低，此種設計不僅具有內部構件容易耗損、偵測不夠準確之缺點，且該彈簧66使用一段時間後，容易有彈性疲乏之情事產生，此將導致該缺氧保護裝置之準確度大幅降低，進而影響到使用者之安全。However, the conventional oxygen-deficient protection device is designed to detect whether the surrounding oxygen concentration is too low through a magnetic and elastic mechanism. This design not only has the disadvantage that the internal components are easily worn out and the detection is not accurate enough, and the spring 66 uses a section. After the time, it is easy to have elastic fatigue, which will lead to a significant reduction in the accuracy of the anoxic protection device, which in turn affects the safety of the user.
有鑑於此，本發明之主要目的在於提供一種缺氧保護裝置，為電子式之設計，不僅不易耗損且具有高準確度。In view of this, the main object of the present invention is to provide an oxygen-deficient protection device which is electronically designed and is not only difficult to wear but also has high accuracy.
