為能更清楚地說明本發明，茲舉較佳實施例並配合圖示詳細說明如後。In order that the present invention may be more clearly described, the preferred embodiments are illustrated in the accompanying drawings.

Heating the water pipe 100, and a thermostat 300, disposed on the outer casing of the strong-throwing water heater, And reciprocatingly rotating within a predetermined angle, and the thermostat 300 has a variable resistor 310. When the thermostat 300 is rotated, the impedance value of the variable resistor 310 can be simultaneously changed.
以上所述之結構與習用非強攻型熱水器無異，其詳細作動方式於此便不再贅述。而本發明與習用不同之處，在於該非強攻型熱水器上更增設有一水溫控制系統，其包含有一電子式瓦斯比例閥10、一阻抗偵測裝置20、一入水溫偵測裝置30、一水量偵測裝置40、以及一控制器50，其中：The structure described above is no different from the conventional non-powered water heater, and the detailed operation mode will not be described here. The difference between the present invention and the conventional one is that a non-powered type water heater is further provided with a water temperature control system, which comprises an electronic gas proportional valve 10, an impedance detecting device 20, a water inlet temperature detecting device 30, and a water amount. a detecting device 40, and a controller 50, wherein:
該電子式瓦斯比例閥10設置於一瓦斯管上，且位於瓦斯供給路徑上，具有可透過電氣訊號進行控制，而調節供給該加熱裝置200的瓦斯量之功效。在實際實施上，該瓦斯比例閥10可為申請人申請之美國專利公開第20090206291A1號所示之「gas flow rate control valve」，係利用電流提供使閥門作比例式開啟，亦即當電流提供越大，閥門開度比例式地增大，所提供之瓦斯流量亦比例式地增大。當然，在實際實施上，該電子式瓦斯比例閥10亦可為步進馬達、或是其它可用來調節瓦斯量之裝置。The electronic gas proportional valve 10 is disposed on a gas tube and is located on the gas supply path, and has the function of controlling the amount of gas supplied to the heating device 200 by being controlled by an electrical signal. In actual practice, the gas proportional valve 10 can be a "gas flow rate control valve" as shown in the applicant's US Patent Publication No. 20090206291A1, which uses a current supply to cause the valve to be proportionally opened, that is, when the current is supplied Large, the valve opening is proportionally increased, and the gas flow rate provided is also proportionally increased. Of course, in practical implementation, the electronic gas proportional valve 10 can also be a stepping motor or other device that can be used to adjust the amount of gas.
該阻抗偵測裝置20用以偵測該溫控器300之該可變電阻310之阻抗值。於本實施例中，該阻抗偵測裝置20為直接量測阻抗值之一阻值量測器，但不以此為限，該阻抗偵測裝置20亦可為電壓量測器或電流量測器，透過量測線路上之電壓或電流，亦可間接測得該可變電阻310之阻抗值。The impedance detecting device 20 is configured to detect an impedance value of the variable resistor 310 of the thermostat 300. In the present embodiment, the impedance detecting device 20 is a resistance measuring device that directly measures the impedance value, but not limited thereto, the impedance detecting device 20 can also be a voltage measuring device or a current measuring device. The impedance value of the variable resistor 310 can also be measured indirectly by measuring the voltage or current on the line.
該入水溫偵測裝置30設於該輸水管100之入水口110附近，用以偵測流入該輸水管100的水的溫度。The water inlet temperature detecting device 30 is disposed near the water inlet 110 of the water pipe 100 for detecting the temperature of the water flowing into the water pipe 100.
該水量偵測裝置40同樣設於該輸水管100之入水口110附近，用以偵測每單位時間內流入該輸水管100的水的水量。The water detecting device 40 is also disposed near the water inlet 110 of the water pipe 100 for detecting the amount of water flowing into the water pipe 100 per unit time.
該控制器50與該阻抗偵測裝置20、該入水溫偵測裝置30、該水量偵測裝置40、以及該電子式瓦斯比例閥10電性連接，用以依據該阻抗偵測裝置20、該入水溫偵測裝置30以及該水量偵測裝置40之偵測結果控制該電子式瓦斯比例閥10。The controller 50 is electrically connected to the impedance detecting device 20, the water inlet temperature detecting device 30, the water detecting device 40, and the electronic gas proportional valve 10, according to the impedance detecting device 20, The water temperature detecting device 30 and the detection result of the water amount detecting device 40 control the electronic gas proportional valve 10.
藉此，上述設計配合下述之溫度控制方法，便可達到控制出水溫度之目的；該方法包含有下列步驟：Thereby, the above design is combined with the following temperature control method to achieve the purpose of controlling the outlet water temperature; the method comprises the following steps:
A.將該溫控器300的該可變電阻310區分為至少兩個阻抗範圍。舉例來說，當該可變電阻之最大阻抗值為10K歐姆時，則可設定0~5K歐姆為第一阻抗範圍，而5K~10K歐姆則設定為第二阻抗範圍。A. The variable resistor 310 of the thermostat 300 is divided into at least two impedance ranges. For example, when the maximum resistance value of the variable resistor is 10K ohms, 0~5K ohms can be set as the first impedance range, and 5K~10K ohms is set as the second impedance range.
B.設定各阻抗範圍之預定出水溫度。舉例而言，當該溫控器300旋動使該可變電阻310之阻抗值位於該第一阻抗範圍內時，則表示希望出水溫度為一第一溫度。而當該溫控器300旋動使該可變電阻310之阻抗值位於該第二阻抗範圍內時，則表示希望出水溫度為一第二溫度；於本實施例中，該第一溫度為65度，而該第二溫度為70度。B. Set the predetermined outlet temperature for each impedance range. For example, when the thermostat 300 is rotated such that the impedance value of the variable resistor 310 is within the first impedance range, it indicates that the desired outlet water temperature is a first temperature. When the temperature controller 300 is rotated to set the impedance value of the variable resistor 310 within the second impedance range, it indicates that the desired outlet water temperature is a second temperature; in the embodiment, the first temperature is 65. Degree, and the second temperature is 70 degrees.
C.利用該阻抗偵測裝置20偵測該可變電阻310之阻抗值位於該第一阻抗範圍或第二阻抗範圍中，並透過該入水溫偵 測裝置30以及該水量偵測裝置40偵測流入該入水口110的水的溫度以及流量。C. The impedance detecting device 20 detects that the impedance value of the variable resistor 310 is in the first impedance range or the second impedance range, and transmits the water temperature detection The measuring device 30 and the water amount detecting device 40 detect the temperature and flow rate of the water flowing into the water inlet 110.
D.利用該控制器50以步驟C偵測之結果計算出升溫至預定出水溫度所需熱能，並依據計算結果控制該電子式瓦斯比例閥10，藉以調節供予該加熱裝置200之瓦斯量，使加熱後自該出水口120流出的水能接近或等於預定出水溫度，而維持在一預定溫度範圍內。D. Using the controller 50 to calculate the heat energy required for the temperature rise to the predetermined water temperature by the result of the step C detection, and controlling the electronic gas proportional valve 10 according to the calculation result, thereby adjusting the amount of gas supplied to the heating device 200, The water flowing out of the water outlet 120 after heating can be brought close to or equal to the predetermined water temperature while being maintained within a predetermined temperature range.
藉此，透過上述之設計，便可依據不同之入水溫以及入水量供予對應之熱能，使得不管是夏天較高水溫之入水、或是冬天較低水溫之入水皆能達到出水位於相同溫度範圍內之目的。另外，上述之水溫控制系統不需要大幅變動原先非強攻型熱水器之結構，透過額外增設之方式，便可使得習用之該非強攻型熱水器夠過該水溫控制系統即可具有溫度控制之功能。Therefore, through the above design, the corresponding heat energy can be supplied according to different water inlet temperatures and water inflows, so that the water entering the water at the higher water temperature in the summer or the water entering the lower water temperature in the winter can reach the same water. The purpose within the temperature range. In addition, the above water temperature control system does not need to greatly change the structure of the original non-powered type water heater, and the additional addition method can make the non-powered water heater of the conventional use of the water temperature control system have the function of temperature control.
值得一提的是，因為使用年限或設置環境之影響因素下，不同之非強攻型熱水器可能會有不同之加熱效能，而使得不同之非強攻型熱水器以同樣熱能加熱時，可能會有出水溫度不一的情形。是以，請參閱圖2，在圖1的架構下，該水量偵測裝置更可於該輸水管100之出水口附近設置一與該控制器電性連接之出水溫偵測裝置60，藉此便可於上述步驟C中，增加偵測自該輸水管100流出的水的溫度，進而透過偵測之入水溫度、入水流量、瓦斯供應量以及出水溫度便可得知各該非強攻熱水器之加熱效能，而後，便可依據各該非強攻熱水器之加熱 效能對應調整供給之瓦斯供應量。換言之，當該出水口120流出的水溫低於預定出水溫度，則加大供予該加熱裝置之瓦斯量；當該出水口120流出的水溫高於預定出水溫度，則降低供予該加熱裝置之瓦斯量，使得於步驟D中之出水溫度能更加接近原先設定之預定出水溫度。It is worth mentioning that, due to the age of use or the influence of the setting environment, different non-powered water heaters may have different heating performances, and different non-powered water heaters may have water temperature when heated by the same heat energy. Different situations. Therefore, referring to FIG. 2, in the structure of FIG. 1, the water detecting device can further provide a water temperature detecting device 60 electrically connected to the controller near the water outlet of the water pipe 100. In the above step C, the temperature of the water flowing out of the water pipe 100 can be increased, and the heating performance of the non-powered water heater can be known through the detected water inlet temperature, the inflow water flow rate, the gas supply amount and the outlet water temperature. And then, according to the heating of each non-powered water heater The efficiency corresponds to the supply of gas supplied by the supplier. In other words, when the water temperature of the water outlet 120 is lower than the predetermined water temperature, the amount of gas supplied to the heating device is increased; when the water temperature of the water outlet 120 is higher than the predetermined water temperature, the heating is lowered. The amount of gas in the device is such that the temperature of the outlet water in step D can be closer to the originally set predetermined outlet temperature.
以上所述僅為本發明較佳可行實施例而已，並不以此為限，除可將該可變電阻區分兩個阻抗範圍外，亦可依需求區分成三個、四個或五個以上，進而達到更精準地溫度控制。另外，本發明之水溫控制系統除適用於上述使用旋鈕式溫控器之非強攻型熱水器外，亦可適用於使用按鈕式溫控器、或是其他透過改變阻抗值進行設定之溫控器的非強攻型熱水器上。再者，舉凡應用本發明說明書及申請專利範圍所為之等效結構與方法變化，理應包含在本發明之專利範圍內。The above description is only a preferred embodiment of the present invention, and is not limited thereto. The variable resistor can be divided into two impedance ranges, and can be divided into three, four or more according to requirements. To achieve more precise temperature control. In addition, the water temperature control system of the present invention is applicable not only to the above-mentioned non-powered type water heater using the knob type thermostat, but also to a button type thermostat or other thermostat which is set by changing the impedance value. The non-powered type of water heater. Furthermore, variations in the structure and method of the invention are intended to be included within the scope of the invention.
