In addition, it is a big problem for the length of heating time and the cost of energy.
又，如中華民國新型專利公告第M404951號『液體加熱器』之專利案，其主要係包含一加熱管、一導電組件及一電連接導電組件的控制器，所述加熱管於其具有導熱性之連續彎曲狀管體上包覆合金電熱層，導電組件以其正、負極導電元件分別接觸所述合金電熱層，藉此，利用合金電熱層通電產生的熱快速的分佈管體上，達到即時加熱的效能。 In addition, the patent of the "Liquid Heater" of the Republic of China New Patent Publication No. M404951 mainly comprises a heating pipe, a conductive component and a controller electrically connected to the conductive component, wherein the heating pipe has thermal conductivity.

Therefore, when the electric heating layer of the alloy is broken or damaged, it is necessary to replace the entire set of continuously curved pipe bodies, which is quite inconvenient.

3.由於使用合金電熱層對液體加熱，使得控制器在功率輸出的控制上較為不容易，而影響到輸出液體溫度之穩定性，恆溫效果不佳。 3. Due to the use of the alloy electric heating layer to heat the liquid, the controller is not easy to control the power output, and affects the stability of the output liquid temperature, and the thermostatic effect is not good.
4.合金電熱層產生的熱能需先傳遞至連續彎曲狀管體，再傳遞至管體內部的液體，以至於熱轉換效率較差，熱能散失的快。 4.

請參閱第四圖所示，本實施例中，所述加熱區段(A)與電熱棒(12)各為六個，首先，對所述控制單元(2)進行溫度設定[例如液體加熱至40℃]，作動時，當所述流體開關(24)偵測到有液體經過，會傳輸訊號至所述控制單元(2)之控制電路板(21)，並執行所述控制元件(22)驅動所述電熱棒(12)，同時透過所述第一液體溫度感測元件(13)感測加熱前之液體溫度[例如20℃]，而所述控制單元(2)透過內建軟件計算上升20℃所需要的總功率，並由每一個所述控制元件(22)分別控制所述電熱棒(12)而分別輸出功率，使其各別功率加總後等於所需總功率，對所述液體管路(11)內的液體進行加溫，同時透過所述第二液體溫度感測元件(14)感測加熱後之液體溫度，並透過訊號傳輸至所述控制單元(2)之控制電路板(21)作回饋，直到達到設定溫度。 Referring to the fourth figure, in the embodiment, the heating section (A) and the electric heating rod (12) are each six.

請參閱第五圖所示，為了提升液體加熱效率，而在輸出總功率固定的條件下，調整每一個所述電熱棒(12)的輸出功率，詳細的說，由於靠近所述液體管路(11)之入口(111)的液體溫度較低，而需要較大的功率來提升溫度，靠近於所述液體管路(11)之出口(112)的液體溫度較高，只需要較小的功率即可提升溫度，在輸出總功率不變的條件下，令每一個所述電熱棒(12)產生之功率值，由靠近所述液體管路(11)之入口(111)的電熱棒(12)往靠近所述液體管路(11)之出口(112)的電熱棒(12)減少，可讓液體加熱效率更好，同時不額外增加功率以達到省能的目的。 Referring to the fifth figure, in order to improve the liquid heating efficiency, the output power of each of the electric heating rods (12) is adjusted under the condition that the total output power is fixed, in detail, due to the proximity to the liquid pipeline ( 11) The inlet (111) has a lower liquid temperature and requires more power to raise the temperature. The liquid near the outlet (112) of the liquid line (11) has a higher temperature and requires less power. The temperature can be raised, and the power value generated by each of the electric heating rods (12) is made by the electric heating rod (12) near the inlet (111) of the liquid pipeline (11) under the condition that the total output power is constant. The reduction of the electric heating rod (12) to the outlet (112) of the liquid line (11) allows the liquid to be heated more efficiently without additional power addition for energy saving purposes.
請參閱第六圖所示，進一步說明，由於所述控制元件(22)控制所述電熱棒(12)作動會產生高溫，若是所述控制元件(22)產生之溫度過高，則會使得所述控制元件(22)損壞而產生故障的情況，為解決此問題，本實施例中，係將所述控制元件(22)貼附固定於所述散熱管路(23)，而作為所述控制元件(22)之散熱裝置，詳細的說，藉由散熱管路(23)內流動的液體吸收所述控制元件(22)產生的熱能，以維持所述控制元件(22)之作動溫度於較低溫，此外，液體在進入所述液體管路(11)前，已先行吸收一些控制元件(22)產生的熱能，而讓液體溫度升高，其手段有助於後續加溫程序，綜合前述，透過此手段可達成穩定控制元件(22)作動溫度、廢熱再利用與先行將液體預熱等目的，其中將液體預熱可同時達 成電力節省與加熱時間縮短的功效，係為較佳的設計。 Referring to the sixth figure, it is further explained that since the control element (22) controls the operation of the electric heating rod (12) to generate high temperature, if the temperature generated by the control element (22) is too high, the In order to solve this problem, in the present embodiment, the control element (22) is attached and fixed to the heat dissipation pipe (23) as the control. The heat sink of the component (22), in particular, absorbs the heat generated by the control element (22) by the liquid flowing in the heat dissipation conduit (23) to maintain the operating temperature of the control component (22) Low temperature, in addition, before entering the liquid pipeline (11), the liquid has first absorbed the heat energy generated by some of the control elements (22), and the liquid temperature is raised, and the means contributes to the subsequent heating process. Through this means, the purpose of stabilizing the control element (22), the waste heat reuse, and the preheating of the liquid can be achieved, wherein the liquid preheating can be simultaneously achieved. The power saving and heating time shortening effect is a better design.
惟以上所述僅係為本發明之較佳實施例，當不能以此限定本發明實施之範圍，即依本發明申請專利範圍及發明說明內容所作簡單的等效變化與修飾，皆屬本發明專利涵蓋之範圍內。 However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications according to the scope of the present invention and the description of the invention are the present invention.
