How to set up the dishwasher

The present invention relates to a washing stroke setting method of the dishwasher, and in particular, the washing stroke setting method of the dishwasher to enable a series of washing process while automatically reset the washing, rinsing stroke, which is a series of washing strokes when dishwashing It is about.

In general, when washing with a dishwasher, a series of washing operations, washing, rinsing, and drying stroke setting are performed by a washing stroke set by a predetermined program.

That is, when the user starts washing, the dishwasher supplies the washing water to the washing room at a predetermined level by a predetermined series of washing strokes, and then drives the heater and the pump and heats the supplied washing water to heat the washing water. After pumping with the pump and sprayed to the dish through the injection nozzle to wash while separating food wastes in the dish, and when the cleaning is completed, proceed with the rinse by a predetermined rinsing frequency is set, the rinse is completed, It is supposed to dry when complete.

As such, the conventional washing stroke setting method of the dishwasher is to perform washing to a predetermined set of washing strokes unconditionally while the user inputs a washing signal. It is impossible to clean and sanitary as much as desired. On the other hand, if the degree of contamination of the dishes is not severe, if the washing process proceeds to the predetermined washing stroke, it not only wastes washing time and power, but also consumes water. In addition, if the contamination of the dishes to be washed is severe or weak, the user may perform rinsing while increasing or decreasing the rinsing stroke in a series of washing cycles, or increasing or decreasing the predetermined number of rinsing cycles. After washing the boil before administration In this case, when the rinsing frequency increases and decreases, when the rinsing cycle is completed a predetermined number of times, the user has to manually rinse the rinsing frequency and proceed with the rinsing. There is a hassle that the user must artificially set and clean.

An object of the present invention is to detect the contamination level contained in the wash water separated from the dish during dish washing, so that the washing time, the number of rinsing is automatically set according to the detected contamination level, the user during the series of washing process contamination state of the tableware As a result, it is intended to enable clean and hygienic cleaning without artificially resetting the washing and rinsing cycle.

In order to realize the above object, the present invention, in washing, rinsing, and drying a series of washing strokes, detects the contamination level of the washing water in the washing stroke, and compares the detected pollution degree with a predetermined reference pollution degree. In the case of severe washing and rinsing with a long washing time and increasing the number of rinsing, if the detected contamination is weak, the washing time is short, washing and rinsing with a decreasing rinsing frequency, and if the detected contamination is the same as the reference pollution Washing and rinsing with a washing time and the number of rinsing, characterized in that the drying to complete.

If the degree of contamination of more than the predetermined washing time, the first washing stroke setting step 24 to reset by increasing than the rinse frequency, and the pollution degree detected in the first pollution degree determining step 23 If the degree of contamination is not greater than or equal to or less than the second pollution degree determining step 25 and the degree of contamination detected in the second degree of pollution degree determining step 25 is equal to a predetermined reference degree of contamination, the predetermined cleaning time and the number of rinsing times are set. If the pollution degree detected in the second washing administration setting step 26 and the second pollution degree determination step 25 is not the same as the predetermined reference pollution degree, the third pollution degree for determining whether the detected pollution degree is less than the predetermined pollution degree In the determination step 27 and the third pollution degree determining step 27, when the detected pollution degree is less than a predetermined pollution degree, a third washing administration setting step 28 is set to decrease the predetermined washing time and the rinsing frequency. In addition, the first, second, and third washing stroke setting steps 24, 26, and 28 are made to be made in the washing step 29 for washing with the washing time and the number of rinses set.

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

First, when the dish is put in the washing room of the dishwasher to wash the dishes with food waste after the completion of the meal, when the cleaning start signal is input to the microcomputer (B) through the driving signal input unit (A), the micom (B) control the operation signal input by the predetermined program, and output the controlled signal to the water supply driver (C) to feed the washing chamber, and the predetermined water level through the water level detector (D). When the water supply is sensed until the water supply is completed, and the water supply is completed at a predetermined level through the water level detection unit (D), the microcomputer (b) goes to the washing water spraying step 21 to control the pump driving unit (E) to wash water. While pumping, it is sprayed on the tableware, and for a predetermined time (2-3 minutes) arbitrarily set, that is, food debris and foreign matter on the tableware are separated.

As described above, in the state where food waste and foreign substances are separated from the tableware, the microcomputer (b) goes to the pollution detection stage 22 to control the pollution detection unit (h) to separate food waste and foreign substances from the dish. The degree of contamination contained in the sensor is detected, and the microcomputer (b) then proceeds to the first pollution degree determination step 23 to determine whether the pollution degree detected from the pollution degree detection unit (H) is equal to or greater than a predetermined reference pollution level. In this case, if the detected pollution level is more than the predetermined reference pollution level, the microcomputer (b) goes to the first washing administration setting step 24 and sets a predetermined washing time and rinsing frequency, and sets the first pollution degree. If the pollution degree detected from the pollution detection unit (H) is not more than a predetermined reference pollution degree by going to the determination step 23, the 2 go to the pollution degree determination step (25) to determine whether the detected pollution degree is equal to the preset reference pollution degree, and if the determined result is the same as the detected pollution degree and the predetermined reference pollution degree, go to the second washing administration setting step (26) The predetermined washing time and the number of rinsing times are set, and if the detected pollution degree in the second pollution degree determination step 25 is not the same as the preset reference contamination level, the microcomputer (b) determines the third pollution degree determination step 27. Go to to determine whether the detected pollution degree is less than the predetermined reference pollution degree, and if the determined contamination level is not less than the predetermined predetermined pollution degree, go to the pollution degree detection step 22 to continue to detect the pollution degree On the other hand, the microcomputer (b) is set to go to the third washing administration setting step 28 to decrease than the predetermined washing time and the number of rinsing times.

When the washing stroke is set according to the detected pollution degree as described above, the microcomputer (b) goes to the washing step 29 and proceeds to the washing stroke set according to the pollution degree, but controls the heater driving part (bar). The washing water is heated while sensing the water temperature heated through the water temperature sensing unit (G), and the heated washing water is sprayed to the dishes by pumping driving of the pump driving unit (e), and the washing time is reset according to the pollution degree. By washing and rinsing with a predetermined number of rinsing when the washing is completed, and when the rinsing is completed by controlling the blower fan drive unit (dri) to drive and dry the blow fan to complete.

As described above, the present invention detects the contamination of the washing water contaminated by food waste and foreign matter separated from the dish by spraying the washing water onto the dish when the water supply is completed and water supply is completed before the dish washing starts. The washing time and rinsing frequency are automatically reset according to the degree of contamination, and a series of cleaning processes are performed in the reset cleaning process, so that the user artificially resets the washing and rinsing cycles according to the contamination status of the dishes during the series of cleaning operations.
