（実施の形態１）
上記構成において図１を参照しながら動作を説明する。まず、通常時の動作を図１（ａ）に沿って説明する。食器７を食器かご６に配置して洗浄槽２内に収納し、洗剤を入れて運転を開始すると、制御手段１０は、まず、ステップ３０にて決められた時間排水側にポンプ４を動作させて残水を排出する。つぎに、ステップ３１にて給水弁（給水手段）３を動作させて給水し、ステップ３２にて洗浄側にポンプ４を動作させ、洗浄ノズル５から洗浄水を噴射して食器７を洗浄する。 (Embodiment 1)
The operation of the above configuration will be described with reference to FIG. First, the normal operation will be described with reference to FIG. When the tableware 7 is placed in the tableware basket 6 and stored in the washing tub 2 and the operation is started after putting the detergent, the control means 10 first operates the pump 4 to the drain side for the time determined in step 30. To discharge residual water. Next, in step 31, the water supply valve (water supply means) 3 is operated to supply water, and in step 32, the pump 4 is operated to the cleaning side, and cleaning water is sprayed from the cleaning nozzle 5 to clean the dishes 7.

洗浄中、ステップ３３にて温度検知手段９で洗浄温度を常に検知し、適切な洗浄温度以上であるかどうか監視している。適切な洗浄温度は５７〜６３℃程度である。洗浄水の温度がこの洗浄温度以上に達すれば、十分に洗浄できたと判断して、洗浄動作を終了し、ステップ３４にて所定時間排水側にポンプを動作させ、洗浄槽２内の水を排水する。ここで所定時間（約７０分）経過しても所定温度に達しない場合は、ヒータ８や温度検知手段９等の異常と判定して、洗浄動作を停止する。   During cleaning, the temperature detection means 9 always detects the cleaning temperature in step 33 and monitors whether the temperature is higher than the appropriate cleaning temperature. A suitable washing temperature is about 57-63 ° C. If the temperature of the washing water reaches the washing temperature or more, it is judged that the washing has been sufficiently performed, and the washing operation is finished. In step 34, the pump is operated to the drain side for a predetermined time, and the water in the washing tank 2 is drained. To do. If the predetermined temperature (about 70 minutes) does not reach the predetermined temperature, it is determined that the heater 8 or the temperature detecting means 9 is abnormal, and the cleaning operation is stopped.

次に、ステップ３５にて給水弁（給水手段）３を動作させて給水し、ステップ３６にて洗浄側にポンプを動作させ、洗浄ノズル５から水を噴射して食器７をすすぎ、ステップ３７にて所定時間排水側にポンプを動作させ、洗浄槽２内の水を排水する。以降ステップ３５〜ステップ３７を何度か繰り返した後、ステップ３８にて給水弁（給水手段）３を動作させて給水し、ヒータ８に通電しつつ、ステップ３９にて洗浄側にポンプを動作させ、洗浄ノズル５から水を噴射して食器７の加熱すすぎを行う。   Next, in step 35, the water supply valve (water supply means) 3 is operated to supply water, in step 36, the pump is operated to the cleaning side, water is sprayed from the cleaning nozzle 5, and the tableware 7 is rinsed. Then, the pump is operated to the drain side for a predetermined time, and the water in the cleaning tank 2 is drained. Thereafter, Steps 35 to 37 are repeated several times, and then the water supply valve (water supply means) 3 is operated to supply water at Step 38 and the heater 8 is energized while the pump is operated to the cleaning side at Step 39. Then, water is sprayed from the washing nozzle 5 to heat and rinse the tableware 7.

この加熱すすぎにおいても、温度検知手段９は、ステップ４０にて洗浄水が加熱すすぎに適した温度に達したかどうかを監視し続けている。加熱すすぎの温度は７０〜８０℃としている。洗浄水の温度がこの加熱すすぎ温度以上に達すれば、十分に加熱すすぎができたと判断して、加熱すすぎ動作を終了し、ステップ４１にて所定時間排水側にポンプを動作させ、洗浄槽２内の水を排水する。なお、この加熱すすぎにおいても、所定時間（約７０分）経過しても所定温度に達しない場合は、ヒータ８や温度検知手段９等の異常と判定して、洗浄動作を停止する。そして、ステップ４２にて食器７を乾燥させる行程を所定時間行い、一連の行程を終了する。   Even in this heating rinse, the temperature detection means 9 continues to monitor whether or not the washing water has reached a temperature suitable for the heating rinse in step 40. The temperature of the heating rinse is 70 to 80 ° C. If the temperature of the washing water reaches or exceeds the heating rinse temperature, it is determined that the heating rinse has been sufficiently performed, the heating rinse operation is terminated, and in step 41, the pump is operated to the drain side for a predetermined time. Drain the water. In this heating rinse, if the predetermined temperature (about 70 minutes) does not reach the predetermined temperature, it is determined that the heater 8 or the temperature detecting means 9 is abnormal, and the cleaning operation is stopped. And the process which dries the tableware 7 is performed for predetermined time in step 42, and a series of processes are complete | finished.

次に、図１（ｂ）に沿って給水消火時の動作を説明する。通常の一連の行程におけるステップ３０〜ステップ４２のすべてで、ステップ４３に示すように、温度検知手段９は、洗浄水あるいは洗浄槽２内の空気の温度が第２の所定温度（１００℃前後に設定する）を超えないかどうかを監視し続けている。ここで、第２の所定温度以上の温度を検知すれば、ステップ４４に進み、ヒータ８への通電を遮断するとともに、その時の行程の動作を停止し、ステップ４５にて異常報知をする。   Next, the operation | movement at the time of water supply fire extinguishing is demonstrated along FIG.1 (b). In all of steps 30 to 42 in a normal series of steps, as shown in step 43, the temperature detecting means 9 is configured so that the temperature of the cleaning water or the air in the cleaning tank 2 is a second predetermined temperature (around 100 ° C.). To keep track of whether or not it exceeds. If a temperature equal to or higher than the second predetermined temperature is detected, the process proceeds to step 44, the power supply to the heater 8 is cut off, the operation of the stroke at that time is stopped, and an abnormality is notified in step 45.

その場合、さらにステップ４５以降も、温度検知手段９は温度検知を連続して続行し、洗浄水あるいは洗浄槽２内の空気の温度がさらに上昇した場合、ステップ４６にて、上記第２の所定温度より高温に設定された所定温度を超えないかどうかを検知して監視を続け、その第２の所定温度を超えれば、ヒータ８の通電が遮断されたにもかかわらず温度上昇が続いていることから、食器７もしくは残滓が発火していると判断して、ステップ４７にて給水弁（給水手段）３を開いて洗浄槽２内に給水を行うとともに、ポンプ４を排水側に動作させて、食器洗い機本体１内の洗浄槽２の内部で消火動作を行い、温度が所定温度もしくは第２の所定温度以下になるか、または所定時間経過後にステップ４８に移行し、食器洗い機としての動作を停止する。   In that case, the temperature detecting means 9 continues the temperature detection continuously after step 45, and when the temperature of the cleaning water or the air in the cleaning tank 2 further rises, in step 46, the second predetermined Monitoring is continued by detecting whether or not a predetermined temperature set higher than the temperature is exceeded, and if the second predetermined temperature is exceeded, the temperature continues to rise even though the heater 8 is de-energized. Therefore, it is determined that the tableware 7 or the residue is ignited, and in step 47, the water supply valve (water supply means) 3 is opened to supply water into the cleaning tank 2, and the pump 4 is operated to the drain side. The fire extinguishing operation is performed inside the washing tub 2 in the dishwasher main body 1, and the temperature falls below the predetermined temperature or the second predetermined temperature, or after a predetermined time elapses, the process proceeds to step 48 to operate as a dishwasher. Stop .

上記の所定温度は、樹脂製の食器類の発火温度以上の１７０〜２００℃に設定しておくのが望ましい。   The predetermined temperature is preferably set to 170 to 200 ° C. which is equal to or higher than the ignition temperature of resin tableware.

なお、本実施の形態では、給水消火時において、温度検知手段９が第２の所定温度以上の温度を検知した後、給水を行うと同時に排水を行うとしたが、給水を行った後、所定時間経過後に排水を行うようにしてもよく、この場合は、給水を有効に利用した消火を行うことができる。また、洗浄槽内の空気の温度が第２の所定温度を超えないかどうかの監視を、通常の一連の行程のすべてで行うこととしたが、洗い、すすぎ、加熱すすぎ、乾燥の一連の行程のうちの単一あるいは任意の複数の行程に限定して監視を行っても、限定的になるものの、同様の効果が得られる。   In the present embodiment, when the water supply is extinguished, the temperature detection means 9 detects the temperature equal to or higher than the second predetermined temperature, and then the water is supplied and drained at the same time. Drainage may be performed after the passage of time, and in this case, fire extinguishing can be performed using water supply effectively. In addition, although it was decided to monitor whether the temperature of the air in the washing tank does not exceed the second predetermined temperature in all of the normal series of steps, a series of steps of washing, rinsing, heating rinsing and drying are performed. Even if the monitoring is limited to a single or a plurality of arbitrary strokes, the same effect can be obtained although it is limited.

以上のように、本発明にかかる食器洗い機は、ヒータ上への可燃物の落下等により発火した場合でも、食器洗い機本体内部での消火が可能となるので、湯沸し、乾燥用ヒータを用いた食器洗い機等に有用である。   As described above, the dishwasher according to the present invention can extinguish fire inside the dishwasher body even when it is ignited due to the fall of combustible materials on the heater, etc. Useful for machine etc.
