為供進一步瞭解本創作構造特徵、運用技術手段及所預期達成之功效，茲將本創作使用方式加以敘述，相信當可由此而對本創作有更深入且具體之瞭解，如下所述：該內電極單元22之該高液位內電極222與該低液位內電極223係由線圈型態導電材質所組成，且該高液位內電極222與該低液位內電極223間互相不碰觸以避免短路，同時該外電極單元與該內電極單元22之間可由該內電極單元22之該密閉絕緣殼體221隔開以防止短路，因此該電容式液位偵測計20係可設於導體溶液中，同時於該容置空間11內之溶液或空氣可作為其介電質，其中，該高液位內電極222與該外電極單元之間形成一第一電容器，同時該低液位內電極223與該外電極單元之間形成一第二電容器，而電容器的電容量與電容器之介電質的介電係數呈正比，當液位變化使介電質改變導致介電係數產生變化，並回傳信號至該控制器40計算與判斷，進而得知液位高低。 In order to further understand the characteristics of the creation of the creation, the use of technical means and the expected results, the use of this creation is described, I believe that this can be a deeper and more specific understanding of the creation, as follows: the internal electrode The high liquid inner electrode 222 and the low liquid inner electrode 223 of the unit 22 are composed of a coil type conductive material, and the high liquid inner electrode 222 and the low liquid inner electrode 223 do not touch each other. The short circuit is avoided, and the outer electrode unit and the inner electrode unit 22 can be separated from the sealed insulating case 221 of the inner electrode unit 22 to prevent short circuit. Therefore, the capacitive liquid level detector 20 can be disposed on the conductor. In the solution, a solution or air in the accommodating space 11 may serve as a dielectric thereof, wherein a first capacitor is formed between the high liquid inner electrode 222 and the outer electrode unit, and the low liquid level is A second capacitor is formed between the electrode 223 and the outer electrode unit, and the capacitance of the capacitor is proportional to the dielectric constant of the dielectric of the capacitor. When the liquid level changes, the dielectric property changes to cause a change in the dielectric constant. And returning the signal to the controller 40 for calculation and judgment, and then knowing the level of the liquid level.
因此當該低液位內電極223與該外電極單元之間，因液位下降而使介電質由水液變成空氣可視為達到低液位，且傳送低液位信號給該 控制器40，經由該控制器40傳送液位不足信號至該閥體控制元件32，使該閥體控制元件32開啟該閥體31，讓外部水液經該進水口12流入該容置空間11。 Therefore, when the low liquid inner electrode 223 and the outer electrode unit change the dielectric from the water liquid to the air due to the liquid level drop, the low liquid level signal is transmitted to the low liquid level signal. The controller 40 transmits a liquid level shortage signal to the valve body control element 32 via the controller 40, so that the valve body control element 32 opens the valve body 31, and the external water liquid flows into the accommodating space 11 through the water inlet 12. .
請再同時參閱第3圖所示，係為本創作較佳實施例之高液位使用示意剖視圖，當該高液位內電極222與該外電極單元之間，因液位上升而使介電質由空氣變成水液時可視為達到高液位，並傳送高液位信號給該控制器40，經由該控制器40傳送液位足夠信號至該閥體控制元件32，使該閥體控制元件32關閉該閥體31，進而關閉該進水口12，同時，該控制器40會傳送加熱信號至該加熱器13，使該加熱器13作動至達到所設定之溫度。 Please refer to FIG. 3 at the same time, which is a schematic cross-sectional view of the high liquid level use of the preferred embodiment of the present invention. When the high liquid internal electrode 222 and the external electrode unit are dielectrically increased due to the liquid level rise, When the air changes from air to liquid, it can be regarded as reaching a high liquid level, and a high liquid level signal is transmitted to the controller 40, and a sufficient liquid level signal is transmitted to the valve body control element 32 via the controller 40 to make the valve body control element. The valve body 31 is closed 32, and the water inlet 12 is closed. At the same time, the controller 40 transmits a heating signal to the heater 13 to activate the heater 13 until the set temperature is reached.
茲，再將本創作之特徵及其可達成之預期功效陳述如下：本創作所提供之具液位偵測開關之加熱桶100，當該控制器40接收到該電容式液位偵測計20之低液位信號，該控制器40會開啟該進水閥30，使水液由該進水口12流入該容置空間11，又當該控制器40接收到該電容式液位偵測計20之高液位信號時，該控制器40會關閉該進水閥30，使該進水口12閉合，讓該加熱器13作動至達到所設定之溫度，其中，該電容式液位偵測計20之該內電極單元22與外電極單元係利用非接觸式電容耦合感測方式偵測液位高低，因此不會因該加熱桶100內水垢、氣泡、原水電阻值不同影響液位偵測而造成誤動作。 Hereafter, the characteristics of the present creation and its achievable expected effects are as follows: The heating bucket 100 with the liquid level detecting switch provided by the present invention, when the controller 40 receives the capacitive liquid level detector 20 The low level signal, the controller 40 will open the water inlet valve 30, so that the water liquid flows into the accommodating space 11 from the water inlet 12, and when the controller 40 receives the capacitive liquid level detector 20 When the liquid level signal is high, the controller 40 closes the water inlet valve 30 to close the water inlet 12, and the heater 13 is activated to reach the set temperature, wherein the capacitive liquid level detector 20 The inner electrode unit 22 and the outer electrode unit detect the liquid level by using a non-contact capacitive coupling sensing method, so that the liquid level detection is not affected by the difference in scale, air bubbles and raw water resistance in the heating barrel 100.
