The washing pump 5 pressurizes the washing water in the washing tank 2 to the washing nozzle 7. The heater 8 is provided in the washing tank 2, and has a function of heating the heating water. The thermistor 14 is disposed outside the cleaning tank 2 and has a function of a temperature detecting unit for detecting the temperature of the washing water.
又，控制部15依據記憶於控制程序之程式，根據熱阻器14等之檢知資訊及由使用者輸入之輸入部(未圖示)的輸入資訊、控制洗碗機之洗淨動作。具體而言，控制部15控制洗淨泵5、洗淨噴嘴7、加熱器8、送風扇13等。藉此，控制由洗淨、清洗、加熱清洗、乾燥之各步驟構成之一連串的洗淨運轉，執行餐具類9之洗淨動作。 Further, the control unit 15 controls the washing operation of the dishwasher based on the detection information stored in the control program and the input information of the input unit (not shown) input by the user, based on the program stored in the control program. Specifically, the control unit 15 controls the washing pump 5, the washing nozzle 7, the heater 8, the blower fan 13, and the like. Thereby, a series of washing operations are performed by each of the steps of washing, washing, heating, washing, and drying, and the washing operation of the tableware 9 is performed.
其次，就本實施形態之重點之洗碗機之洗淨步驟中之動作及作用，一面參照圖1一面使用圖2加以說明。 Next, the operation and action in the washing step of the dishwasher which is the focus of the present embodiment will be described with reference to Fig. 1 with reference to Fig. 1 .
圖2為顯示同實施形態之洗碗機之各步驟中之洗淨泵及加熱器之控制程序與洗淨水之溫度變化的圖。 Fig. 2 is a view showing a control procedure of a washing pump and a heater and a temperature change of the washing water in each step of the dishwasher of the embodiment.
首先如圖2所示，控制部15在洗淨步驟開始時， 開啟(ON)加熱器8，並且開啟洗淨泵5。接著，進行以加熱器8將洗淨水加熱，並且由洗淨噴嘴7噴射以洗淨泵5所壓送之洗淨水之步驟。 First, as shown in FIG. 2, when the control unit 15 starts the washing step, The heater 8 is turned "ON" and the washing pump 5 is turned on. Next, a step of heating the washing water by the heater 8 and injecting the washing water pumped by the pump 5 by the washing nozzle 7 is performed.
其次，業經加熱之洗淨水的溫度到達第1預定溫 度時，在預定時間內進行一面噴射洗淨水，一面停止洗淨水之加熱的步驟。 Secondly, the temperature of the heated washing water reaches the first predetermined temperature. In the case of a degree, the step of heating the washing water is stopped while the washing water is sprayed for a predetermined period of time.
然後，再次開啟加熱器8，執行一面加熱洗淨水，一面以洗淨噴嘴7噴射洗淨水之步驟。 Then, the heater 8 is turned on again, and the washing water is sprayed on the washing nozzle 7 while the washing water is heated.
接著，上述步驟進行到業經加熱器8加熱之洗淨水之溫度到達第2預定溫度為止。 Next, the above steps are performed until the temperature of the washing water heated by the heater 8 reaches the second predetermined temperature.
其次，洗淨水之溫度到達第2預定溫度時，控制部15關閉(OFF)加熱器8及洗淨泵5。 Next, when the temperature of the washing water reaches the second predetermined temperature, the control unit 15 turns off (OFF) the heater 8 and the washing pump 5.
藉由以上，執行本實施形態之洗碗機之洗淨步驟。 By the above, the washing step of the dishwasher of this embodiment is performed.
再者，本實施形態之洗碗機中，在洗淨步驟開始時，若洗淨水之溫度高於第1預定溫度時，則從開始時不進行加熱器8之洗淨水的加熱。接著，控制部15以開始時之洗淨水的溫度為第1預定溫度，進行運轉控制。 Further, in the dishwasher of the present embodiment, when the temperature of the washing water is higher than the first predetermined temperature at the start of the washing step, the washing water of the heater 8 is not heated from the start. Next, the control unit 15 performs operation control such that the temperature of the washing water at the start is the first predetermined temperature.
又，本實施形態之洗碗機中，當洗淨水之溫度在上述預定時間之期間內，下降預定溫度幅度(例如，1.5℃)時，控制部15反覆加熱器8之開啟、關閉動作，控制洗淨水之溫度。藉此，進行運轉控制，使洗淨水之溫度維持在第1預定溫度。 Further, in the dishwasher of the present embodiment, when the temperature of the washing water drops within a predetermined temperature range (for example, 1.5 ° C) during the predetermined time period, the control unit 15 repeats the opening and closing operations of the heater 8 . Control the temperature of the wash water. Thereby, the operation control is performed to maintain the temperature of the washing water at the first predetermined temperature.
以下，就本實施形態之洗碗機之動作及作用，參照圖1並使用圖2加以具體的說明。 Hereinafter, the operation and action of the dishwasher of the present embodiment will be specifically described with reference to Fig. 1 and Fig. 2 .
再者，本實施形態之洗碗機之洗淨動作是由至少上述之洗淨步驟、清洗步驟、加熱清洗步驟等所構成。 Further, the washing operation of the dishwasher of the present embodiment is constituted by at least the above-described washing step, washing step, heating and washing step, and the like.
首先，當洗碗機之運轉開始時，控制部15打開給水閥3，開始朝洗淨槽2內給水。 First, when the operation of the dishwasher is started, the control unit 15 opens the water supply valve 3 and starts to supply water into the washing tank 2.
其次，在給水完成後，如圖2所示，執行洗淨步驟。接著，在洗淨步驟之開始時，通電至洗淨泵5及加熱器8(ON)。藉此，進行一面以加熱器8將洗淨水加熱，一面由洗淨噴嘴7噴射洗淨水之步驟(以下，稱為「步驟1」)。 Next, after the water supply is completed, as shown in Fig. 2, the washing step is performed. Next, at the start of the washing step, the cleaning pump 5 and the heater 8 are turned on (ON). In this way, the step of spraying the washing water by the washing nozzle 7 while heating the washing water by the heater 8 (hereinafter referred to as "step 1") is performed.
此時，藉由熱阻器14等之溫度檢知部，檢知到洗淨水之溫度已到達第1預定溫度(例如，約40℃)時，則停止加熱器8之洗淨水的加熱預定時間(例如，5分鐘以上)。此時，維持洗淨泵5之通電，進行繼續來自洗淨噴嘴7之洗淨水的噴射之步驟(以下、稱為「步驟2」)。 At this time, when the temperature detecting unit such as the thermistor 14 detects that the temperature of the washing water has reached the first predetermined temperature (for example, about 40° C.), the heating of the washing water of the heater 8 is stopped. Scheduled time (for example, more than 5 minutes). At this time, the energization of the washing pump 5 is maintained, and the step of continuing the spraying of the washing water from the washing nozzle 7 (hereinafter referred to as "step 2") is performed.
再者，宜將第1預定溫度設定為例如洗碗機用之專用洗劑之酵素活性化最有效的作用溫度、例如40℃。此理由是因為通常酵素是以蛋白質為主成分而構成，因此高溫時會變性而活性降低。因此，定為可達到酵素之高活性與高溫之變性的平衡之40℃左右。藉此，洗劑成分可確實地浸透於餐具或調理器具等之污垢，可使酵素對污垢有效地作用。又，即使是對於急速地增加熱時而硬化，污垢變得難以掉落之污垢，亦可藉由維持約40℃之溫度，而使洗劑成分有效地作用於污垢。例如，藉由使第1預定溫度為約 40℃前後，對於例如蛋等之蛋白質污垢、或飯粒等之澱粉污垢的洗淨特別有效。又，維持第1預定溫度之預定時間宜為約5分鐘以上。藉此，可使洗劑之酵素有效地作用。 Further, it is preferable to set the first predetermined temperature to a working temperature at which the enzyme for a special lotion for a dishwasher is most effective, for example, 40 °C. This reason is because the enzyme is usually composed of a protein as a main component, and thus denatured at a high temperature and the activity is lowered. Therefore, it is determined that the balance between the high activity of the enzyme and the denaturation of the high temperature can be achieved at about 40 °C. Thereby, the lotion component can be surely impregnated with the dirt of the tableware or the conditioning device, and the enzyme can effectively act on the dirt. Further, even if it is hardened when the heat is rapidly increased, the dirt becomes difficult to fall, and the lotion component can be effectively applied to the dirt by maintaining the temperature of about 40 °C. For example, by making the first predetermined temperature approximately Before and after 40 ° C, it is particularly effective for the washing of protein soil such as eggs or starch stains such as rice grains. Further, the predetermined time for maintaining the first predetermined temperature is preferably about 5 minutes or longer. Thereby, the enzyme of the lotion can be effectively acted upon.
其次，如圖2所示，使洗淨水之溫度維持在第1 預定溫度(例如，約40℃)預定時間(例如，5分鐘以上)後，再次通電(ON)到加熱器8。藉此，一面加熱洗淨水，一面進行藉洗淨噴嘴7噴射洗淨水之步驟(以下、稱為「步驟3」)，直到洗淨水之溫度到達第2預定溫度(例如，70~80℃)。第2預定溫度是為了洗淨油污等，而設定在比油之融点40~50℃更高的溫度、70~80℃之溫度。藉此，可將油污等溶於洗淨水。其結果是，可使油污等之污垢容易掉落。 Next, as shown in Figure 2, the temperature of the washing water is maintained at the first After a predetermined temperature (for example, about 40 ° C) for a predetermined time (for example, 5 minutes or more), the heater 8 is turned on again. Thereby, the washing water is sprayed by the washing nozzle 7 (hereinafter referred to as "step 3") while the washing water is heated, until the temperature of the washing water reaches the second predetermined temperature (for example, 70 to 80) °C). The second predetermined temperature is set to a temperature higher than the melting point of the oil by 40 to 50 ° C and a temperature of 70 to 80 ° C in order to wash off the oil or the like. Thereby, oil stains and the like can be dissolved in the washing water. As a result, dirt such as oil stains can be easily dropped.
再者，在上述步驟3之洗淨中，係以洗淨水之溫 度到達第2預定溫度時結束之例來說明，但不限於此。例如，亦可控制為藉由足以到達第2預定溫度的時間控制，結束步驟3之洗淨。也就是說，洗淨水之溫度在到達第2預定溫度後，亦可繼續加熱清洗步驟預定時間。此種情況下，由於關閉加熱器8，因此由第2預定溫度開始漸漸地降低洗淨水之溫度。可是，由於在第2預定溫度附近進行加熱清洗步驟，因此可維持高洗淨性能。 Furthermore, in the washing of the above step 3, the temperature of the washing water is used. The example in which the degree is reached when the second predetermined temperature is reached is described, but is not limited thereto. For example, it may be controlled to end the cleaning of step 3 by time control sufficient to reach the second predetermined temperature. That is to say, after the temperature of the washing water reaches the second predetermined temperature, the heating step can be continued for a predetermined time. In this case, since the heater 8 is turned off, the temperature of the washing water is gradually lowered from the second predetermined temperature. However, since the heating and washing step is performed in the vicinity of the second predetermined temperature, high washing performance can be maintained.
又，本實施形態中，是以第1預定溫度為40℃左 右為例來說明，但不限定於此。例如，在洗碗機中，若選擇頑固油污專用之洗淨行程時，亦可將第1預定溫度設定為70~80℃。此時，洗淨水之溫度由洗淨步驟之初期保持在 高溫。因此，可更有效率地將頑固的油污垢洗落。 Further, in the present embodiment, the first predetermined temperature is 40 ° C left. The right is described as an example, but is not limited thereto. For example, in a dishwasher, if a washing course dedicated to stubborn oil is selected, the first predetermined temperature may be set to 70 to 80 °C. At this time, the temperature of the washing water is maintained at the initial stage of the washing step. high temperature. Therefore, stubborn oil stains can be washed off more efficiently.
另一方面，若洗碗機連接於機外之貯熱水槽或給熱水器，60℃前後之熱水在給水後不久會給水到洗淨槽2內。此時，若有如蛋污垢等之污垢附著於餐具等，則會因為熱而污垢的表面急速地硬化。因此，洗劑成分會無法浸透污垢。其結果是，洗淨性能可能會變差。 On the other hand, if the dishwasher is connected to the hot water storage tank outside the machine or to the water heater, the hot water before and after 60 °C will supply water to the washing tank 2 shortly after the water supply. At this time, if dirt such as egg dirt adheres to the tableware or the like, the surface of the dirt due to heat is rapidly hardened. Therefore, the lotion component will not be able to saturate the dirt. As a result, the cleaning performance may be deteriorated.
因此，本實施形態之洗碗機亦可控制成，若洗淨步驟開始時之洗淨水的溫度比第1預定溫度高時，控制部15由洗淨步驟開始時，會停止加熱器8進行洗淨水之加熱，而為第1預定溫度。藉此，可防止洗淨性能之降低。 Therefore, the dishwasher of the present embodiment can be controlled such that when the temperature of the washing water at the start of the washing step is higher than the first predetermined temperature, the control unit 15 stops the heater 8 when the washing step is started. The heating of the washing water is the first predetermined temperature. Thereby, the deterioration of the washing performance can be prevented.
又，本實施形態中，將大量的餐具或調理器具放置於洗碗機時，餐具或調理器具等被吸熱，洗淨水的溫度降低。因此，在步驟2中，維持第1預定溫度變困難。其結果是，有時候洗劑之酵素無法有效地作用，洗淨性能降低。 Further, in the present embodiment, when a large number of dishes or conditioning tools are placed in the dishwasher, the dishes, the conditioning instruments, and the like are absorbed, and the temperature of the washing water is lowered. Therefore, in step 2, it is difficult to maintain the first predetermined temperature. As a result, sometimes the enzyme of the lotion does not function effectively, and the washing performance is lowered.
因此，本實施形態之洗碗機是當洗淨水之溫度在預定時間之期間內下降到預定溫度幅度(例如，1.5℃)時，控制部15亦可進行運轉控制，反覆加熱器8之開啟、關閉，使洗淨水之溫度維持在第1預定溫度。藉此，即使是放置大量的餐具或調理器具等情況，亦可維持第1預定溫度。其結果是，防止洗劑之活性降低，而可防止如污垢變得難以掉落之污垢的洗淨性能降低。 Therefore, in the dishwasher of the present embodiment, when the temperature of the washing water drops to a predetermined temperature range (for example, 1.5 ° C) for a predetermined period of time, the control unit 15 can also perform operation control, and the heater 8 is turned on again. And shutting off, maintaining the temperature of the washing water at the first predetermined temperature. Thereby, even if a large number of tableware or conditioning apparatus is placed, the first predetermined temperature can be maintained. As a result, the activity of the lotion is prevented from being lowered, and the cleaning performance of the dirt such as the dirt which is hard to fall is prevented from being lowered.
藉由上述，執行本實施形態之洗碗機之洗淨步驟。 By the above, the washing step of the dishwasher of this embodiment is performed.
其次，如圖2所示，在進行上述洗淨步驟後、控 制部15將污垢的洗淨水排水。接著將以重新給水之乾淨的洗淨水清洗餐具類9的清洗步驟執行例如2次到3次左右。 Next, as shown in FIG. 2, after performing the above washing step, control The preparation unit 15 drains the washing water of the dirt. Next, the washing step of washing the dishes 9 with the clean water to be re-watered is performed, for example, two to three times.
其次，進行以加熱器8所加熱之高溫(70~80℃)之洗淨水清洗餐具類9之加熱清洗步驟。 Next, a heating and washing step of washing the tableware 9 with the high-temperature (70 to 80 ° C) washing water heated by the heater 8 is performed.
其次，本實施形態之洗碗機亦可因應需要而進行不圖示之乾燥步驟。具體而言，乾燥步驟藉由圖1所示之送風扇13將外部空氣吸入洗淨槽2內。接著，藉由加熱器8所加熱之外部空氣的熱風使餐具類9乾燥。藉此，執行乾燥步驟。 Next, the dishwasher of this embodiment can be subjected to a drying step (not shown) as needed. Specifically, the drying step draws outside air into the cleaning tank 2 by the blower fan 13 shown in FIG. Next, the tableware 9 is dried by the hot air of the outside air heated by the heater 8. Thereby, a drying step is performed.
其次，完成乾燥步驟時，結束洗碗機之洗淨運轉。 Next, when the drying step is completed, the washing operation of the dishwasher is ended.
再者，清洗步驟、加熱清洗步驟或、乾燥步驟等之各步驟中之動作及作用與習知一般的洗碗機同樣，因此省略詳細的說明。 Further, the operations and actions in the respective steps of the washing step, the heating washing step, and the drying step are the same as those of the conventional dishwasher, and thus detailed descriptions thereof will be omitted.
