すぎ工程が終了し洗浄工程が終了する。BACKGROUND OF THE INVENTION A conventional method of operating a dishwasher of this type will be described with reference to FIGS. 4 and 5. After storing tableware, cooking utensils, etc. in a predetermined place in the dish basket 1 and placing them in the washing tank 2, detergent is added and operation is started. First, a predetermined amount of washing water 10 is flushed by the operation of the water supply valve 3. The washing water 10 pressurized by the washing pump 4 is then injected from the injection hole 6 of the washing nozzle 5 together with the detergent to carry out the main washing process shown in FIG. 5. That is, in the main washing step, the heater 7 provided in the washing tank 2 is energized to heat the washing water 10 and the tableware 12 to a predetermined temperature. After the washing process for a predetermined period of time, the washing water 10 containing the dirt washed off from the tableware 12 is drained by the drain pump 8. Continue to add new washing water 1.
After rinsing the dishes 12 soiled with detergent and leftover food by supplying water 0 and spraying washing water 10 from the washing nozzle 6, the process of draining the washing water to the outside of the machine is repeated four times in succession. The rinsing process is completed and the cleaning process is completed.

最高温度は約６０℃に設定されている。Next, the main washing process of the washing process will be explained. In general, protein stains such as eggs are denatured when the temperature exceeds about 55° C., and cannot be washed with the jet power of the cleaning nozzle 5. Also, to activate the enzymes in the detergent and increase its cleaning power, use 10% of the washing water.
Since the optimum temperature for washing is between 40°C and 60°C, the temperature of the washing water 10, which can wash protein stains well, is between 40°C and 50°C.
It will be between 5℃. However, if the maximum water temperature of the washing water 10 is set below the protein deterioration temperature, oil and fat stains will be removed during washing, and the maximum temperature of the washing water 10 in the main washing process is set at approximately 60°C. ing.

温度以上で洗浄することにより膨潤し洗浄される。In FIG. 2, Ta is the temperature of the washing water 21 in the washing process in this embodiment, Tb is the temperature of the washing water in the washing process in the conventional dishwasher operating method, and Tc is the temperature maintained during the washing process in this embodiment. Indicates the temperature of the given wash water. The operating method of this embodiment is to energize the heating device 29, and
is heated to a temperature Ta. That is, when the temperature Ta of the cleaning water 21 reaches a predetermined temperature Tc (45° C. in the embodiment), the control device 31 detects the water temperature and the heating device 29 is de-energized. After the temperature of the cleaning water reaches a predetermined temperature Tc and a predetermined period of time has elapsed, the heating device 29 is energized again to heat the cleaning water 21. At this time, the temperature at which protein stains are easily removed is
The temperature is between the activation temperature of detergent enzymes (approximately 40°C) and the temperature at which proteins begin to denature (approximately 55°C), but in the conventional operating method, the washing water temperature Tb is between 40°C and 55°C. The running time is about 6 minutes.On the other hand, in the operating method of this embodiment, the above-mentioned time is about 12 minutes.Therefore, according to the operating method of this embodiment, the cleaning performance against protein stains can be improved. In addition, since oil and fat stains are easily dissolved and removed when the maximum temperature during the main washing process is 55°C or higher, there is no difference in cleaning performance between the conventional operating method and the operating method of this embodiment. , starch stains swell and are cleaned by washing at temperatures above the activation temperature of the detergent.
このようにして、本洗い工程が終了するとすすぎ工程、
乾燥工程と進み運転を終了する。In this way, when the main washing process is completed, the rinsing process begins.
Proceed with the drying process and end the operation.

When the temperature of the washing water is above a predetermined temperature before starting the main washing process in which the washing water is injected with the washing nozzle 26, the temperature of the washing water is lowered to below the predetermined temperature by the cooling device 30, and then,
This controls the start of the main washing process.

経て洗浄工程を終了する。FIG. 3 shows an operating method when hot water from a water heater is used as the wash water 21. In the figure, Td is the temperature of the washing water 21 in the washing process when the dishwasher of this embodiment is operated, Te is the temperature of the washing water 21 in the washing process when the conventional dishwasher is operated, and Tc is the washing process. Indicates the temperature of a given wash water held in it. As shown in the figure, the conventional dishwasher uses two wash water
Since the main washing step is started immediately after the water supply in step 1, if the washing water temperature is higher than the protein denaturation temperature, the protein will be denatured in a short time and washing will not be possible. However, in the dishwasher of this embodiment, when the supplied washing water is higher than the preset temperature Tc, the detection sensor 31a detects the water temperature, the control device 31 controls the cooling device 30, and the temperature Td is lowered. It is cooled down to a predetermined temperature Tc or lower. Then, after the temperature of the washing water 21 becomes equal to or lower than a predetermined temperature, the main washing process similar to that of the first embodiment is started. At this time, in the main washing step, the protein is washed at a temperature below the denaturation temperature of the protein for a predetermined period of time, so that protein stains can be washed in the same manner as in the first embodiment. After the main washing process is completed, the cleaning process is completed through a rinsing process and a drying process.
なお、第１、第２の実施例において、乾燥工程後に加熱
装置２９、冷却装置３０により、洗浄槽２２内を一定温
