In step 101, the main controller 12 checks whether the drain operation select switch is turned on from the key operation panel unit 10, and proceeds to step 102 when the drain operation select switch is turned on. In step 102, the main controller 12 sets a drainage operation mode and proceeds to step 103. In step 103, the main controller 12 checks whether the rest state is in a rest state, and if not in the rest state, proceeds to step 104 to perform the operation and returns to step 103. However, if the state is in step 103, the flow proceeds to step 105 and the main controller 12 displays the drainage operation screen on the display unit 14 and proceeds to step 106. In step 106, the main controller 12 outputs the drain pump on signal through the communication interface 24. Then, the sub controller 30 receives the drain pump on signal through the communication interface 30 and outputs the drain pump driving signal to the load driving circuit 36. The load driving circuit 36 opens the drain pump 42 to drain the contaminated water from which the dishes are washed in the washing tank to the external sewer pipe. Then, in step 107, the main controller 12 outputs the water supply valve on signal through the communication interface 24. Then, the sub controller 30 receives the water supply valve ON signal through the communication interface 30 and outputs the water supply valve driving signal to the load driving circuit 36. The load driving circuit 36 opens the water supply valve 40 to allow cold water to be injected through the nozzle into the washing tank, thereby washing the inside of the washing tank. Then, in step 108, the main controller 12 checks whether the set time (for example, 5 seconds) has elapsed, and proceeds to step 109 when the set time has elapsed. The setting time is 5 seconds, but can be adjusted arbitrarily. In step 109, the main controller 12 outputs a water supply valve off signal through the communication interface 24. Then, the sub-control unit 30 receives the water supply valve off signal through the communication interface 30 and outputs the water supply valve blocking signal to the load driving circuit 36. The load driving circuit 36 blocks the water supply valve 40 so that cold water is not supplied into the washing tank. Then, in step 110, the main controller 12 outputs the drain pump off signal through the communication interface 24. Then, the sub controller 30 receives the drain pump off signal through the communication interface 30 and outputs a drain pump cutoff signal to the load driving circuit 36. The load drive circuit 36 shuts off the drain pump 42. Thereafter, in step 111, the main controller 12 displays the drainage operation completion screen on the display unit 14, and proceeds to step 112. In step 112, the main control unit 12 causes the drainage operation completion sound to be generated, for example, five times through the buzzer 18 and ends the program.

3a and 3b is a control flow chart for the cleaning operation according to an embodiment of the present invention.

1 and 3, the cleaning operation control operation of the present invention will be described in detail.

In operation 201, the main controller 12 checks whether the cleaning reservation selection switch is turned on from the key operation panel unit 10, and proceeds to step 202 when the cleaning reservation selection switch is turned on. In step 202, the main controller 12 sets a cleaning reservation and proceeds to step 203. The cleaning schedule is set by selecting a date and time to be cleaned. In step 203, the main controller 12 checks whether it is in a rest state, and if it is not in a rest state, proceeds to step 204 to perform a corresponding operation and returns to step 203. However, in step 203, if it is in a rest state, the process proceeds to step 205, and the main controller 12 checks whether the cleaning reservation time has been reached and proceeds to step 206 if the cleaning reservation time is reached. In step 206, the main controller 12 displays the cleaning reservation screen on the display unit 14, and proceeds to step 207. In step 207, the main controller 12 checks whether the switch on signal is input from the key manipulation panel unit 10, and proceeds to step 208 if the switch on signal is input, and proceeds to step 209 if the switch on signal is not input. If any key signal is inputted from the key operation panel unit 10 in step 207, the main control unit 12 deletes the cleaning reservation date screen displayed on the display unit 14 in step 208. Proceed. In step 209, the main controller 12 outputs the drain pump on signal through the communication interface 24. Then, the sub controller 30 receives the drain pump on signal through the communication interface 30 and outputs the drain pump driving signal to the load driving circuit 36. The load driving circuit 36 opens the drain pump 42 to drain the contaminated water from which the dishes are washed in the washing tank to the external sewer pipe. The drainage time may for example be drained for 30 seconds. After the drainage is completed for 30 seconds, after the drain pump 42 is turned off, the main controller 12 outputs the scaled valve on signal through the communication interface 24 in step 210. Then, the sub controller 30 receives the scaled valve on signal through the communication interface 30 and outputs the scaled valve driving signal to the load driving circuit 36. The load driving circuit 36 opens the scale rinse valve 46 so that the scale rinse is supplied into the rinsing tank. The scale rinse supply, for example, is applied for 12 seconds and stopped. Thereafter, in step 211, the main controller 211 outputs the heater driving control signal through the communication interface 24. Then, the sub controller 30 receives the heater drive control signal through the communication interface 30 and outputs the heater drive signal to the load drive circuit 36. The load driving circuit 36 drives the heater 48 to heat the body water of the rinsing tank. After that, in step 212, the main controller 34 checks whether the set temperature (eg, 80 ° C.) of the washing water is detected from the temperature sensing unit 34 installed in the rinsing tank, and then proceeds to step 213. In step 213, the main controller 120 outputs the heater cutoff control signal through the communication interface 24. Then, the sub controller 30 receives the heater cutoff control signal through the communication interface 30 and outputs the heater cutoff signal to the load driving circuit 36. The load driving circuit 36 shuts off the driving of the heater 48. Then, in step 214, the main controller 12 checks whether the set time (for example, 10 minutes) has elapsed, and if the set time has not elapsed, returns to step 215 to call the rinse tank as heated hot water. However, if the time set in step 214 has elapsed, the process proceeds to step 216 and outputs a rinsing pump on signal through the communication interface 24. Then, the sub-control unit 30 receives the heme pump on signal through the communication interface 30 and outputs a heme pump drive signal to the load driving circuit 36. The load driving circuit 36 drives the rinsing pump 44 to clean the inside of the washing tank with heated hot water. In operation 217, the main controller 12 outputs the water supply valve on signal through the communication interface 24. Then, the sub controller 30 receives the water supply valve ON signal through the communication interface 30 and outputs the water supply valve driving signal to the load driving circuit 36. The load driving circuit 36 opens the water supply valve 40 to clean the inside of the rinsing tank and the washing tank with cold water inside the rinsing tank. In step 218, if the low water level is detected from the water level detection unit 32 through the sub-control unit 30, the main controller 12 returns to step 217 to continuously supply cold water, and proceeds to step 219 if the low water level is not detected. In step 219, the main controller 12 checks whether the high water level is detected from the water level detector 32 through the sub-control unit 30, and when the high water level is detected, the main controller 12 proceeds to step 220. The water supply valve off signal is output through the communication interface 24. Then, the sub controller 30 receives the water supply valve off signal through the communication interface 30 and outputs the water supply valve shutoff signal to the load driving circuit 36. The load driving circuit 36 prevents the cold water from being cut off from the water supply valve 40. Then, in step 221, the main controller 12 checks whether the set rinsing frequency (for example, 4 times) is reached to set the rinsing frequency. If not, return to step 217 to repeat the above-described operation, and if the set number of rinsing cycles to proceed to step 222. In step 222 the main controller 12 outputs the rinse pump off signal through the communication interface (24). Then, the sub controller 30 receives the rinsing pump off signal through the communication interface 30 and outputs the rinsing pump cutoff signal to the load driving circuit 36. The load driving circuit 36 drives the rinsing pump 44 to be driven. Then, in step 223, the main controller 12 outputs the drain pump on signal through the communication interface 24. Then, the sub controller 30 receives the drain pump on signal through the communication interface 30 and loads the load. A drain pump driving signal is output to the driving circuit 36. The load driving circuit 36 drives the drain pump 42 to discharge the rinsed wash water in the washing tank to an external drain pipe, and the main control in step 224. 12, the main controller 12 outputs the water supply valve on signal through the communication interface 24. Then, the sub controller 30 receives the water supply valve on signal through the communication interface 30 and load-loading circuit 36 The load driving circuit 36 opens the feed valve 40 so that cold water is injected through the nozzle to the wash tank to wash the wash tank. After turning on the supply valve 40, in step 225, the main controller 12 checks whether the set time (for example, 5 seconds) has elapsed, and proceeds to step 226 if the set time has elapsed. The setting time is 5 seconds, but can be adjusted arbitrarily. In step 226, the main controller 12 outputs a water supply valve off signal through the communication interface 24. Then, the sub-control unit 30 receives the water supply valve off signal through the communication interface 30 and outputs the water supply valve blocking signal to the load driving circuit 36. The load driving circuit 36 blocks the water supply valve 40 so that cold water is not supplied into the washing tank. Then, in step 227, the main controller 12 outputs the drain pump off signal through the communication interface 24. Then, the sub controller 30 receives the drain pump off signal through the communication interface 30 and outputs a drain pump cutoff signal to the load driving circuit 36. The load drive circuit 36 stops the driving of the drain pump 42. Thereafter, the main control unit 12 displays the cleaning stop screen on the display unit 14 in step 228 and proceeds to step 229. In step 229, the main controller 12 causes the cleaning completion sound to be generated, for example, five times by the buzzer 18, and ends the program.

The drainage operation completion sound or cleaning completion sound is described as an example that occurs five times, but can be adjusted in the range of 2 to 15 times.
