The water supply step 20 for supplying water to the water, the first washing step 21 for washing dishes for a predetermined time (2-3 minutes) when the water supply is completed in the water supply step 20, and the first washing step ( 21, the first cleaning completion determination step 22 to determine whether the cleaning time is completed, and if the cleaning is completed in the first cleaning completion determination step 22, the pollution degree detecting step (23) for detecting the degree of contamination contained in the washing water ), A first pollution degree determining step 24 for determining whether the pollution degree detected in the pollution degree detecting step 23 is greater than or equal to a predetermined predetermined pollution degree, and the pollution degree determined in the first pollution degree determining step 24 is pre-set. More than the set pollution Determination of the amount of detergent corresponding to the pollution degree, the first detergent amount input determination and display step 25, and if the pollution degree determined in the first pollution degree determination step 24 is not more than the predetermined pollution degree, the predetermined predetermined If the pollution degree detected in the second pollution degree determination step 26 and the second pollution degree determination step 26 are equal to a predetermined pollution degree, the detergent dosage amount corresponding to the pollution degree is determined and displayed. A third pollution degree determination step of determining whether or not the pollution level detected in the second detergent dose input and display step 27 and the second pollution degree determination step 26 are not equal to or less than the predetermined pollution level. If the contamination degree detected in the step 28 and the third pollution degree determination step 28 is not less than or equal to the predetermined predetermined contamination level, the contamination level is detected again and the predetermined predetermined error is detected. If the salinity is less than, the amount of detergent input corresponding to the contamination level is determined, and the third detergent amount input determination and display step 29 is displayed, and the first, second and third detergent amount input determination and display steps 25, 27 ( After the input of detergent amount determined in 29), the washing, rinsing, and drying are performed in a series of washing administration steps 30.

Referring to the operation of the present invention made as described above are as follows.

First, put the dishes to be washed in the dishwasher, and then power on the dishwasher, the microcomputer (b) of the dishwasher maintains the initialization state, and go to the water supply step 20 first by a predetermined program predetermined water supply drive unit (C) to control the water supply to the predetermined washing water, and to control the heater driving unit (bar) to heat the washing water to be supplied, the water level is sensed through the water level detection unit (d) to complete the water supply.

When the water supply is completed, go to the first washing step 21 in the microcomputer (b) to control the pump driving unit (e) to drive the pump to spray the water supplied wash water to the dishes to wash the food residue on the dishes. The dish is washed for a predetermined washing time (2-3 minutes).

Subsequently, the microcomputer (b) determines whether the first washing time is completed by the washing completion determination step 22, and if the washing is not completed, the washing is continued, and if the washing is completed, the pollution detection step is completed. Go to (23) to control the pollution detection unit (G) to detect the contamination level of the washing water containing the food waste, the detected pollution degree goes to the first pollution degree determination step 24 predetermined predetermined If it is determined that the pollution degree of the abnormality is greater than the predetermined contamination level is determined as a result of the determination, the microcomputer (b) determines that the contamination of the tableware is severe, go to the first detergent amount input decision and display step 25 The display unit (a) is controlled to determine and display the amount of detergent corresponding to the severe contamination level, but the first pollution determination step 24 If the detected contamination level is not more than the predetermined pollution level, the microcomputer (b) proceeds to the second pollution determination step 26 to determine whether the detected pollution level is equal to the predetermined pollution level. As a result, if the detected pollution level is equal to the predetermined predetermined pollution level, the microcomputer (b) determines that the pollution level is not severe and goes to the second detergent dosage decision and display step 27 to control the display unit (h) to not have the pollution level. The amount of detergent corresponding thereto is determined and displayed. On the other hand, if the detected pollution degree is not equal to the predetermined predetermined pollution degree, the microcomputer (b) goes to the third pollution degree determination step 28 and the detected pollution degree is preset. It is determined whether or not the predetermined pollution level is below. In this case, the detected pollution level is not equal to or less than the predetermined pollution level. If it is determined that the detection is not properly performed in the micom (b), it is repeatedly performed from the pollution degree detecting step 23, while the predetermined pollution degree detected in the third pollution degree determining step 28 is preset. If the degree of contamination is less than the microcomputer (b) determines that the degree of contamination in the tableware is low, go to the third detergent amount determination and display step (29) to control the display unit (a) so that the amount of detergent input corresponding to the pollution degree is weak. Will be decided and displayed.
