食器洗い機dishwasher
　本発明は、洗浄槽に溜められた洗浄水を加熱しながら洗浄ノズルより食器類に向けて洗浄水を噴射して食器類を洗浄する食器洗い機に関する。 The present invention relates to a dishwasher for cleaning dishes by spraying wash water from a washing nozzle toward dishes while heating washing water stored in a washing tank.
　従来技術による食器洗い機の構成について説明する。図６は、従来の食器洗い機の側断面図である。図７は、従来の食器洗い機の制御構成を示すブロック図である。図８は、従来の食器洗い機の洗い工程の動作を示すフローチャートである。図９は、従来の食器洗い機の洗浄水温度および運転状況を示す説明図である。 The configuration of a conventional dishwasher will be described. FIG. 6 is a side sectional view of a conventional dishwasher. FIG. 7 is a block diagram showing a control configuration of a conventional dishwasher. FIG. 8 is a flowchart showing the operation of the washing process of the conventional dishwasher. FIG. 9 is an explanatory diagram showing a washing water temperature and an operation state of a conventional dishwasher.
　従来、この種の食器洗い機は、図６に示すように構成していた（例えば、特許文献１参照）。以下、その構成について説明する。図６に示すように、食器洗い機の本体２０は、内部に洗浄槽２１が設けられている。この洗浄槽２１の底部に排水口３が設けられている。この排水口３に連通したポンプ室に洗浄モータ４によって駆動される洗浄ポンプ５が配設されている。洗浄ポンプ５は洗浄水を洗浄槽２１の内部に循環させる。この循環は、次のような経路で行われる。まず、洗浄水が排水口３から洗浄ポンプ５に吸い込まれる。次に、洗浄水は洗浄ポンプ５より洗浄槽２１の内底部において回転可能に配設された洗浄ノズル６に供給される。最後に、洗浄水はこの洗浄ノズル６から食器類７に向けて噴射され、食器類７を洗浄した後、再び排水口３に戻る。 Conventionally, this type of dishwasher has been configured as shown in FIG. 6 (see, for example, Patent Document 1). Hereinafter, the configuration will be described. As shown in FIG. 6, the main body 20 of the dishwasher is provided with a washing tank 21 inside. A drain port 3 is provided at the bottom of the cleaning tank 21. A cleaning pump 5 driven by a cleaning motor 4 is disposed in a pump chamber communicating with the drain port 3. The cleaning pump 5 circulates cleaning water inside the cleaning tank 21. This circulation is performed by the following route. First, cleaning water is sucked into the cleaning pump 5 from the drain port 3. Next, the cleaning water is supplied from the cleaning pump 5 to the cleaning nozzle 6 that is rotatably disposed in the inner bottom portion of the cleaning tank 21. Finally, the washing water is sprayed from the washing nozzle 6 toward the dishes 7, and after washing the dishes 7, the washing water returns to the drain port 3 again.
　洗浄ノズル６と洗浄槽２１の底部との間には、洗浄水加熱用のヒータ８が配設されている。制御部２２は洗浄水温度検知部であるサーミスタ２３により、洗浄水が所定温度に達したことを洗浄槽２１の底部の温度から間接的に検知し、ヒータ８への通電を停止する。また、洗浄ノズル６の上方には、食器かご１１が設置されている。食器かご１１は、食器類７を整然と配置することで食器類７に対して洗浄水を効果的に噴射し、食器類７の洗浄を効率的に行えるように構成されている。 A heater 8 for heating cleaning water is disposed between the cleaning nozzle 6 and the bottom of the cleaning tank 21. The controller 22 indirectly detects that the cleaning water has reached a predetermined temperature from the temperature at the bottom of the cleaning tank 21 by the thermistor 23 that is a cleaning water temperature detection unit, and stops energization of the heater 8. A table basket 11 is installed above the cleaning nozzle 6. The tableware basket 11 is configured so that the tableware 7 is arranged in an orderly manner so that washing water is effectively jetted onto the tableware 7 and the tableware 7 can be cleaned efficiently.
　また、洗浄槽２１は前方に開口しており、その前面部に、前方に開閉自在な蓋１２が取り付けられている。排水ポンプ１３は、排水口３から洗浄水を吸い込み、排水ホース１４を通して洗浄水を機外に排出するように構成されている。 Further, the cleaning tank 21 is opened forward, and a lid 12 that can be opened and closed forward is attached to the front surface thereof. The drain pump 13 is configured to suck the cleaning water from the drain port 3 and discharge the cleaning water to the outside through the drain hose 14.
　洗浄槽２１内に溜められる洗浄水は給水ホース１５から供給される。制御部２２は、洗浄槽２１に連通した水位検知部１６により所定水位まで洗浄水が供給されたことを検知すると、給水弁１７を閉じて洗浄水供給を停止する。 The cleaning water stored in the cleaning tank 21 is supplied from the water supply hose 15. When the control unit 22 detects that the cleaning water is supplied to a predetermined water level by the water level detection unit 16 communicating with the cleaning tank 21, the control unit 22 closes the water supply valve 17 and stops the supply of the cleaning water.
　乾燥用送風ファン１８は、洗浄槽２１内に機外から空気を送り込み、食器類７表面などから発生する水蒸気を、蓋１２に設けた排気口１９より機外へ排出し、食器類７を乾燥させる。 The drying fan 18 feeds air from outside the machine into the cleaning tank 21, discharges water vapor generated from the surface of the tableware 7 and the like to the outside through the exhaust port 19 provided in the lid 12, and dries the tableware 7. Let
　制御部２２と各負荷は図７に示すように接続されており、食器洗い機は制御部２２により運転が制御される。図８および図９に示すように、食器洗い機の運転工程は洗い工程、すすぎ工程、加熱すすぎ工程、乾燥工程の４工程から構成されている。洗い工程では、制御部２２は水道から給水ホース１５を通じて洗浄水を所定水量まで給水する（ステップＳ２１）。その後、制御部２２は洗浄ポンプ５とヒータ８に通電し、洗浄水温度が第１の所定温度（例えば、５７℃）に達するまで運転する（ステップＳ２２、Ｓ２３）。洗浄水温度が第１の所定温度に達すると、制御部２２はヒータ８の通電を停止する（ステップＳ２４）。その後、制御部２２は運転時間が所定時間になるまで洗浄ポンプ５を連続動作させて洗浄を行う（ステップＳ２５、Ｓ２６）。その後、制御部２２は排水ポンプ１３を動作させて洗浄槽２内の洗浄水を排水して（ステップＳ２７）、次工程（すすぎ工程）へ進める。 The control unit 22 and each load are connected as shown in FIG. 7, and the operation of the dishwasher is controlled by the control unit 22. As shown in FIGS. 8 and 9, the operation process of the dishwasher is composed of four steps of a washing step, a rinsing step, a heating rinsing step, and a drying step. In the washing process, the control unit 22 supplies the washing water from the water supply to the predetermined amount of water through the water supply hose 15 (step S21). Thereafter, the controller 22 energizes the cleaning pump 5 and the heater 8 and operates until the cleaning water temperature reaches a first predetermined temperature (for example, 57 ° C.) (steps S22 and S23). When the washing water temperature reaches the first predetermined temperature, the control unit 22 stops energization of the heater 8 (step S24). Thereafter, the control unit 22 performs cleaning by continuously operating the cleaning pump 5 until the operation time reaches a predetermined time (steps S25 and S26). Thereafter, the control unit 22 operates the drain pump 13 to drain the cleaning water in the cleaning tank 2 (step S27), and proceeds to the next process (rinsing process).
　すすぎ工程では、制御部２２は排水ポンプ１３によりそれまでの汚れた洗浄水を排水した後、新しい洗浄水を洗浄槽２１内に溜め、ヒータ８に通電せず洗浄ポンプ５のみの通電で食器類７を所定時間すすぐ動作を２回繰り返す。加熱すすぎ工程では、制御部２２は排水ポンプ１３によりそれまでの洗浄水を排水した後、新しい洗浄水を洗浄槽２１内に溜め、洗浄ポンプ５とヒータ８に通電し、洗浄水温度が第２の所定温度（例えば、７０℃）に達するまで運転して食器類７をすすぐ。乾燥工程では、制御部２２は排水ポンプ１３により洗浄水を排水した後、乾燥用送風ファン１８に通電しながら、ヒータ８へ断続的に通電する運転を所定時間行う。 In the rinsing process, the control unit 22 drains the dirty cleaning water so far by the drain pump 13, then stores new cleaning water in the cleaning tank 21, and supplies only the cleaning pump 5 without energizing the heater 8. The operation of rinsing 7 for a predetermined time is repeated twice. In the heating and rinsing process, the control unit 22 drains the washing water so far by the drainage pump 13, stores new washing water in the washing tank 21, energizes the washing pump 5 and the heater 8, and the washing water temperature is the second. Rinse tableware 7 by driving until a predetermined temperature (for example, 70 ° C.) is reached. In the drying process, the controller 22 drains the cleaning water by the drain pump 13 and then performs an operation of intermittently energizing the heater 8 while energizing the drying fan 18 for a predetermined time.
　上記のような構成の従来の食器洗い機では、運転プログラムが製造者により運転コースごとに一意に決められていた。よって、洗浄槽２１内に導かれる給水温度の高低に関わらず同じ温度設定の運転プログラムで食器洗い機を運転していた。 In the conventional dishwasher configured as described above, the driving program is uniquely determined for each driving course by the manufacturer. Therefore, the dishwasher was operated with the operation program having the same temperature setting regardless of the level of the feed water temperature guided into the cleaning tank 21.

　本実施の形態１の食器洗い機の本体１は、図１から図４に示すように、本体１の内部に洗浄槽２が設けられている。洗浄槽２内に食器かご１１が設けられている。回転可能な洗浄ノズル６は、この食器かご１１に収容した食器類７に洗浄水を噴射して食器類７を洗浄する。洗浄水は、洗浄槽２の底部に設けた加熱部のヒータ８により昇温される。 The main body 1 of the dishwasher according to the first embodiment is provided with a washing tank 2 inside the main body 1 as shown in FIGS. A table basket 11 is provided in the washing tank 2. The rotatable washing nozzle 6 sprays washing water on the dishes 7 accommodated in the dish basket 11 to wash the dishes 7. The temperature of the cleaning water is raised by the heater 8 of the heating unit provided at the bottom of the cleaning tank 2.
　洗浄槽２の底面裏側には、洗浄槽２内の洗浄水の温度を測定する洗浄水温度測定部のサーミスタ９が取り付けられている。サーミスタ９は、洗浄槽２の底面の温度から間接的に洗浄水の温度を測定する。本実施の形態１においては、このサーミスタ９は、水道から給水される水の温度を測定する給水温度測定部を兼用するように構成されている。制御部１０は、サーミスタ９の出力電圧を検知している。制御部１０は表示部２４を一体に有しており、ＬＥＤの発光により使用者に対して表示を行う。 A thermistor 9 of a cleaning water temperature measuring unit for measuring the temperature of the cleaning water in the cleaning tank 2 is attached to the bottom side of the bottom surface of the cleaning tank 2. The thermistor 9 measures the temperature of the cleaning water indirectly from the temperature of the bottom surface of the cleaning tank 2. In the first embodiment, the thermistor 9 is configured to also serve as a water supply temperature measuring unit that measures the temperature of water supplied from the water supply. The control unit 10 detects the output voltage of the thermistor 9. The control unit 10 has a display unit 24 integrally, and displays to the user by light emission of the LED.
　次に本実施の形態１の食器洗い機の動作及び作用を説明する。洗浄ポンプ５、洗浄ノズル６、ヒータ８等を使用しての食器洗い機としての基本動作は、従来例の食器洗い機と同様である。以下、従来例の食器洗い機とは相違する、本発明の特徴ある構成に関わる動作と作用について詳細に説明する。 Next, the operation and action of the dishwasher according to the first embodiment will be described. The basic operation of the dishwasher using the washing pump 5, the washing nozzle 6, the heater 8, etc. is the same as that of the conventional dishwasher. Hereinafter, operations and actions related to the characteristic configuration of the present invention, which are different from the conventional dishwasher, will be described in detail.
　制御部１０は食器洗い機の運転の洗い工程を開始すると、給水弁１７に通電し、水道から給水ホース１５を通じて洗浄水を洗浄槽２へ供給する。また、制御部１０は水位検知部１６により所定水量まで洗浄水が溜まったことを検知すると、給水弁１７への通電を停止して洗浄水の供給を止める（ステップＳ１）。 When the washing process of the operation of the dishwasher is started, the control unit 10 energizes the water supply valve 17 and supplies cleaning water from the water supply to the cleaning tank 2 through the water supply hose 15. Further, when the control unit 10 detects that the cleaning water has accumulated up to a predetermined amount by the water level detection unit 16, the control unit 10 stops energization to the water supply valve 17 and stops the supply of the cleaning water (step S1).
　制御部１０は、洗浄運転を開始してから所定時間（例えば１分間）経過後のサーミスタ９の出力電圧から給水温度を測定し、今回の給水温度と設定する。所定時間の経過を待って給水温度を測定する理由は、洗浄槽２内へ導かれた洗浄水の温度が洗浄槽２の壁を介してサーミスタ９へ伝わるためには時間が必要なためである。 The control unit 10 measures the water supply temperature from the output voltage of the thermistor 9 after a predetermined time (for example, 1 minute) has elapsed since the start of the cleaning operation, and sets the current water supply temperature. The reason for measuring the feed water temperature after a predetermined time has elapsed is that it takes time for the temperature of the cleaning water introduced into the cleaning tank 2 to be transmitted to the thermistor 9 through the wall of the cleaning tank 2. .
　この洗浄水の給水温度が所定温度Ｔ０（例えば１３℃）以下の場合（ステップＳ２のＮｏ）、制御部１０は洗浄水の昇温を停止する目標温度Ｔ１を第１の目標温度（例えば５７℃）と設定する（ステップＳ３）。一方、洗浄水の給水温度が所定温度Ｔ０（例えば１３℃）よりも高い場合（ステップＳ２のＹｅｓ）、制御部１０は洗浄水の昇温を停止する目標温度Ｔ１を第２の目標温度（例えば５２℃）と設定する（ステップＳ４）。その後、制御部１０はヒータ８と洗浄モータ４に通電して、洗浄水を加熱しながら洗浄ポンプ５を駆動することで洗浄運転を行う（ステップＳ５）。 When the cleaning water supply temperature is equal to or lower than a predetermined temperature T0 (for example, 13 ° C.) (No in step S2), the control unit 10 sets the target temperature T1 for stopping the temperature increase of the cleaning water to the first target temperature (for example, 57 ° C.). ) Is set (step S3). On the other hand, when the feed water temperature of the cleaning water is higher than a predetermined temperature T0 (for example, 13 ° C.) (Yes in Step S2), the control unit 10 sets the target temperature T1 for stopping the temperature increase of the cleaning water to the second target temperature (for example, 52 ° C.) (step S4). Thereafter, the control unit 10 energizes the heater 8 and the cleaning motor 4, and performs the cleaning operation by driving the cleaning pump 5 while heating the cleaning water (step S5).
　そして、洗浄水の温度が目標温度Ｔ１以下の場合（ステップＳ６のＮｏ）、ステップＳ５に戻って制御部１０はヒータ８と洗浄モータ４の通電を継続する。一方、洗浄水の温度が目標温度Ｔ１より高い場合（ステップＳ６のＹｅｓ）、制御部１０はヒータ８の通電を停止する（ステップＳ７）。その後、制御部１０は洗浄ポンプ５を運転時間が所定時間に達するまで連続動作させる（ステップＳ８、Ｓ９）。そして、制御部１０は洗浄ポンプ５の運転時間が所定時間に達すると排水ポンプ１３を動作させて洗浄槽２内の洗浄水を排水して（ステップＳ１０）、次工程（すすぎ工程）へ進める。 When the temperature of the cleaning water is equal to or lower than the target temperature T1 (No in step S6), the control unit 10 returns to step S5 and continues energization of the heater 8 and the cleaning motor 4. On the other hand, when the temperature of the washing water is higher than the target temperature T1 (Yes in Step S6), the control unit 10 stops energization of the heater 8 (Step S7). Thereafter, the control unit 10 causes the cleaning pump 5 to continuously operate until the operation time reaches a predetermined time (steps S8 and S9). Then, when the operation time of the cleaning pump 5 reaches a predetermined time, the control unit 10 operates the drain pump 13 to drain the cleaning water in the cleaning tank 2 (Step S10), and proceeds to the next process (rinsing process).
　洗浄水の温度が高い場合は、温度が低い場合と比較して、食器類７に付着した汚れをふやかすとともに、使用者により投入される洗剤成分に含まれる酵素の働きをより活性化するので、洗浄能力が高い。よって、給水ホース１５から洗浄槽２内へ導かれる洗浄水の温度が比較的高い場合は、洗浄運転の初めから高い洗浄能力の洗浄水で食器類７に付着した汚れを洗うことになる。このため、洗浄水の昇温を停止する目標温度を低めに変更しても十分な洗浄効果が得られる。 When the temperature of the washing water is high, as compared with the case where the temperature is low, the dirt adhering to the tableware 7 is softened, and the function of the enzyme contained in the detergent component added by the user is more activated. High cleaning ability. Therefore, when the temperature of the cleaning water led from the water supply hose 15 into the cleaning tank 2 is relatively high, the dirt adhering to the dishes 7 is washed with the cleaning water having a high cleaning ability from the beginning of the cleaning operation. For this reason, even if the target temperature for stopping the temperature rise of the cleaning water is changed to a lower value, a sufficient cleaning effect can be obtained.
　これにより給水温度が所定温度より高い場合は、洗い工程における消費電力量を低く抑えることができ、食器洗い機はより省エネの運転ができる。 This allows the power consumption in the washing process to be kept low when the water supply temperature is higher than the predetermined temperature, and the dishwasher can be operated more energy-saving.
　本実施の形態１においては、給水温度測定部は、洗浄槽２内の洗浄水温度測定部であるサーミスタ９を兼用しているので、新たに給水温度測定部を搭載することなく、食器洗い機はより省エネに運転することができる。 In the first embodiment, the feed water temperature measuring unit also serves as the thermistor 9 that is the washing water temperature measuring unit in the washing tank 2, so that the dishwasher can be used without newly installing the feed water temperature measuring unit. You can drive more energy-saving.
　また、制御部１０は、運転開始から給水温度確定までは表示部２４に設けた「省エネ」ＬＥＤ２５を点滅させて、給水温度測定中であることを表示する。そして、制御部１０は、給水温度測定の結果、給水温度が所定温度Ｔ０より高く、給水温度が所定温度Ｔ０よりも低い場合と比べて、目標温度Ｔ１を低く設定した場合には運転終了までＬＥＤ２５を点灯させる。すなわち、制御部１０は、洗い工程における消費電力量を低く抑えることができ、より省エネの運転ができる場合は運転終了までＬＥＤ２５を点灯させる。これにより、食器洗い機が省エネに運転できるかを確認していることや、省エネに運転していることを使用者に知らせることができる。その結果、例えば早朝の給水温度が比較的低いときに運転するよりも、昼間などの給水温度が比較的高い時間帯に運転する方が省エネになることを使用者に理解してもらうことができ、省エネ運転の励行を推進することができる。 Further, the control unit 10 blinks the “energy saving” LED 25 provided on the display unit 24 from the start of operation until the water supply temperature is determined, and displays that the water supply temperature is being measured. Then, as a result of the feed water temperature measurement, the control unit 10 determines that the LED 25 is used until the end of the operation when the target temperature T1 is set lower than when the feed water temperature is higher than the predetermined temperature T0 and the feed water temperature is lower than the predetermined temperature T0. Lights up. That is, the control unit 10 can keep the power consumption in the washing process low, and if more energy-saving operation is possible, the control unit 10 turns on the LED 25 until the operation is completed. Thereby, it is possible to notify the user that the dishwasher has been confirmed that it can be operated in an energy-saving manner and that the dishwasher is being operated in an energy-saving manner. As a result, users can understand that it is more energy efficient to drive during times when the water supply temperature is relatively high, such as during the day, rather than driving when the water supply temperature in the early morning is relatively low. Encourage energy-saving driving.
