Abstract

PURPOSE:To economize time and water by a process wherein, when temp. of a cleaning fluid is at least at a specified temp., operation for feeding hot water is performed and when the temp. is at the specified value or lower, cleaning of tableware and discharging cleaning fluid are performed and these operations are repeated several times and, when the temp. of the cleaning fluid reaches the specified temp. or higher, operation for feeding hot water is performed and when it does not reach the temp., operation for feeding water is performed. CONSTITUTION:When temp. of fed cleaning fluid is at least a specified temp. T1 detected by means of a temp. sensor 28, a cleaning pump 11 is driven while a heater 12 is energized and a main washing accompanied with heating the cleaning fluid is performed. On the other hand, when the temp. of the cleaning fluid is not at least T1, prewashing and discharging of the fluid are performed for specified times and when the temp. of fed cleaning fluid reaches at least T1, above described main washing and the successive operation are performed but if it is judged that the temp. does not reach at least T1, until the counted value N of the number of times of prewashing and discharging of the fluid reach a specified number, intermediate washing of the tableware to be cleaned accompanied with heating of the cleaning fluid caused by heat generation by a heater 12 and driving of the cleaning pump 11 is performed. In addition, when the temp. of the cleaning fluid is elevated, a course of operation for feeding water is performed.

On the other hand, if it is determined in the previous step S8 that the temperature of the supplied cleaning liquid is not higher than the predetermined value T1, "1" is added to the count value N of the number of pre-cleaning / drainage liquids ( Step S16), and thereafter whether or not the count value N of the number of times of prewashing / draining has reached a predetermined number (for example, “3”), that is, whether or not prewashing / draining has been performed a predetermined number of times. If it is determined that the predetermined number of times has not been performed (step S17), the process returns to step S4,
The process goes to step S8 through steps S5 to S7. If it is determined in step S8 that the temperature of the supplied cleaning liquid has reached the predetermined value T1 or higher, the process proceeds to step S9 to perform the operations after the previous main wash, but not to the predetermined value T1 or higher. If it is determined, the process goes to step S17 via step S16, and again in step S17,

When the hot water is supplied and operated, the hot water temperature is usually low, but after a certain amount of time, the hot water will be supplied at a sufficiently high temperature. While the temperature is judged to be low, the cold water is discharged by discharging the cleaning liquid, and when the temperature of the supplied cleaning liquid rises, the hot water supply operation course can be executed to ensure that the hot water supply operation course can be executed. , The operating time can be shortened as compared with the case of executing the water supply operation course that takes time to raise the temperature of the low temperature cleaning liquid containing cold water.
Power consumption can also be reduced.

Furthermore, as described above, when washing the dishes to be washed and discharging the washing liquid are repeated, if the temperature of the washing liquid does not rise even if it is repeated to some extent, it has no hot water supply capability due to failure of the hot water supply equipment. Therefore, by executing the water supply operation course in such a situation, it is possible to avoid the situation in which the operation does not proceed, and it is possible to surely wash the dishes to be washed to the end.

In the dishwasher according to the first aspect of the present invention, the dishwasher includes temperature detecting means for detecting the temperature of the cleaning liquid, and when the temperature of the supplied cleaning liquid is determined to be equal to or higher than a predetermined value from the detection result. When the hot water supply operation course is executed and it is determined that the temperature is equal to or lower than the predetermined value, the dish to be cleaned is washed and the cleaning liquid is discharged, and the temperature of the cleaning liquid reaches or exceeds the predetermined value while repeating the predetermined number of times. The hot water supply operation is executed when the judgment is made, and the hot water supply operation is carried out by providing the control means for executing the water supply operation course when it is judged that the temperature of the cleaning liquid does not reach the predetermined value or more even if it is repeated a predetermined number of times. When the course should be executed, it can be surely done, and the operating time can be surely shortened, and in that case, when the hot water supply operation course cannot be executed without wasting water. , And you can perform the water supply operation course instead possible to ensure cleaning of the cleaned dishes.
