The present invention relates to a rinsing method of a dishwasher, and more particularly, to a rinsing method of a dishwasher, which allows rinsing while reducing water and power consumption in the last rinsing stroke.

In a conventional dishwasher, the dishwasher is washed and rinsed at a predetermined water level and a predetermined water temperature, and then the water supplied to a high temperature (72 ° C) is used to sterilize and dry the dishes in the last rinsing cycle. Sterilization rinsing is performed while heating, and the dishes are then dried by the latent heat of high temperature.

In the sterilization rinsing and drying by heating the water supplied to a high temperature (72 ℃), it takes a considerable time to raise the water of the high water level to a high temperature (72 ℃) not only increases the overall washing time In addition, there was a problem that consumes a lot of unnecessary power due to the heating up to the high temperature.

Accordingly, an object of the present invention is to reduce the waste time and power consumption by disinfecting rinsing while reducing the heating time by supplying the washing water supplied in the last sterilization rinse at the time of dish washing to a predetermined level.

In order to realize the above object, the present invention is characterized in that the sterilization rinsing is performed while water is pumped at a predetermined water level at a predetermined time interval during the last rinsing of a series of washing strokes during dish washing, heating at a predetermined time interval, and sensing the water temperature. It is done.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic control block diagram of a dish washing machine used in the present invention, and includes a driving signal input unit (A) for inputting a series of washing administrative operation signals for dish washing, and an input signal inputted from the driving signal input unit (A). The microcomputer (b) which controls the washing administrative operation by a predetermined program and outputs a signal corresponding to the controlled signal, and the water supply unit which receives the control signal output from the microcomputer (b) and supplies the inside of the dishwasher. (C), a water level detecting unit (D) for detecting the level of the washing water supplied from the water supply driving unit (C), and a heater driving unit (E) for heating the washing water supplied from the water supply driving unit (C) with a heater; Water temperature sensing unit (bar) for detecting the water temperature of the washing water heated by the heater driving unit (e), and pump driving unit (p) for washing dishes by pumping the washing water heated by the heater driving unit (e). , If the cleaning by the control signal of the microprocessor (B) is complete, it is composed of a drain ET (H) to a multiple.

Figure 2 is a flow chart for the sterilization rinsing method of the dishwasher applied to the present invention, a rinsing step (20) and the rinsing in progress in the rinsing step 20, the rinsing step is completed, a series of washing stroke is completed Last rinsing determination step 21 to determine the application, the last rinsing determination step 21, if the last rinsing water supply step 22 to supply a predetermined water level (medium water level), and the water supply in the water supply step 22 Water supply completion determination step 23 for determining whether the water level is completed at the predetermined water level (medium water level or less) and, if the water supply is completed in the water supply completion determination step 23, the heater to drive the heater to heat the washing water A driving step 24, a pumping step 25 for pumping on and off at predetermined time intervals while the washing water is being heated in the heater driving step 24, and a pumping step in the pumping step 25 Of wash water in Water temperature detection step 26 for detecting the temperature, the water temperature determination step 27 for determining whether the water temperature detected in the water temperature detection step 26 is higher than the high temperature (72 ℃) a predetermined temperature, and the water temperature determination step When the water temperature determined in (27) reaches a predetermined temperature, the heater is turned off (28) to turn off the heater, and the rinsing is determined by determining whether the rinsing is completed while the heater is turned off in the heater off step (28). The rinse completion step (29) of repeating the above steps until the completion is to be made.

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

First, when the dish to be washed in the dishwasher to wash the dish, and then the operation signal input unit (A) to input the driving signal to be washed into the microcomputer (B), the microcomputer (B) predetermined program predetermined First, water is supplied by controlling the water supply driving unit (c), and the water level is controlled by detecting the water level detection unit (D) so as to detect a predetermined level, that is, a high water level, and by controlling the heater driving unit (e). The water level is heated, and the pump driving part (g) is controlled to wash the dish while spraying the dish with the nozzle while pumping the heated washing water.

Subsequently, when the dish washing is completed, the microcomputer (b) proceeds to the rinsing step 20 according to a predetermined program and performs the rinsing while repeatedly performing the above process. In step (b), the final rinse completion step 21 determines whether the current rinse is the last rinse stroke, and if the determination result is not the last rinsing, the rinsing is continued continuously. 22) to control the water supply driver 22 to supply water below a predetermined level, i.e., below the water level, and at the microcomputer (b), go to the water supply completion judging step 23, and the water level is a predetermined level It is determined whether the water supply is completed above or below the water supply until the predetermined water level is reached, and then the microcomputer (b) goes to the heater driving step 24 and While driving the heater by controlling the drive unit (E) is to heat the wash water to the water supply predetermined water level.

At this time, the microcomputer (b) goes to the pumping step (25) to the pump driving unit (g) in order to prevent the occurrence of Cavitation phenomenon of the washing water that is supplied to the water level below the predetermined water level and heated to the pump driving unit (g) at predetermined time intervals Intermittently pumping the heated washing water while driving and stopping.

During the intermittent pumping as described above, the microcomputer (b) goes to the water temperature sensing step 26 to control the water temperature sensing part bar to sense the water temperature heated by the water supply, and at this time, to the water temperature judging step 27. In this case, it is determined whether the detected water temperature reaches a predetermined temperature, that is, a high temperature (72 ° C.). If the determination result does not reach the predetermined water temperature, the microcomputer (b) wash water from the heater driving step 24 at a predetermined water temperature. Rinsing is performed while pumping until it reaches a temperature, and when the water temperature detected in the water temperature determination step 27 reaches a predetermined temperature, that is, a high temperature (72 ° C.), the heater off step 28 in the microcomputer (b) Go to and control the heater driving unit (e) to turn off the heater so that it is no longer over a predetermined temperature, go to the rinse completion step (29) to determine whether the last rinse currently in progress is completed, at this time If the final rinsing is not completed, the microcomputer (b) performs rinsing until the final rinsing is completed while repeatedly performing the heater driving step 24, and then in the final rinsing completion determination step 29 As a result of the determination, the final rinsing is to control the drainage driving unit (H) to complete the washing while draining the rinsing water.

As described above, in the present invention, when the last rinsing stroke during dish washing and rinsing, the water level is supplied to the medium level, heated to a predetermined water temperature, and rinsed while pumping, thereby rinsing while heating at a faster time. This will provide the effect of reducing the waste of water and power consumption.
