The present invention relates to a method of washing a dishwasher, and more particularly, to a method of washing a dishwasher to obtain a clean washing effect by varying the injection amount according to the degree of contamination of the dish to be washed.

In general, the dishwasher is washed by the injection amount of the washing water sprayed from the spray nozzle, the spray nozzle is rotated by the pressure of the water pumped by the pump located on the lower portion of the dish placed on the washing unit located on the upper portion It will be washed.

However, in the case of the spray nozzle, the rotational speed is rotated at a constant rotational speed according to the pumping amount of the pump, and the contamination degree of the dish to be washed is changed with respect to the constant rotational speed of the spraying nozzle, thereby contaminating by the constant rotational speed. It is difficult to clean both sanitary and clean dishes of varying degrees. However, when the dishwashing is performed mainly on the highly polluted dishes, the washing time is not only long, but also the waste of water is severe. On the contrary, when the dishwashing is focused on the weakly polluted dishes, the washing time is shortened. Severe dishware has a problem that can not expect hygienic dishwashing is not properly washed.

Therefore, an object of the present invention is to separate the dishes to be cleaned in the washing unit according to the degree of contamination, and to clean the dishes at a spray amount varying the rotational speed of the injection nozzle according to the degree of contamination, thereby cleaning within a predetermined cleaning time. It is intended to obtain a cleaning effect.

In order to realize the above object, the present invention classifies the dishes to be washed in the washing tank according to the degree of contamination, and varies the spraying amount according to the degree of contamination of the placed dishes, but rotates the spray nozzle on the dishes with high contamination. Spraying while slowing, and the contamination is not severe dishware is characterized in that the cleaning is made while rotating the rotation of the jet nozzle at a constant speed.

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

When the motor is rotated at low speed in the low speed step 45 or at the normal speed in the motor speed control step 46, it is determined whether the predetermined predetermined washing time is completed. It is to be done to the washing completed plate step 47 to perform repeatedly.

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

First, the dishes to be cleaned are placed on a shelf 1 located in the washing unit 2, and the dishes are divided into the naked eyes according to the degree of contamination, and thus the dishes are divided into the shelves 1, that is, as shown in FIG. Difficult-to-contaminate utensils are placed in parts A and C, and weakly-contaminated utensils are placed in parts B and D and placed in the washing section (2). When the stroke is input, the microcomputer (b) performs the dish washing while controlling the input washing stroke by a predetermined program, that is, in the microcomputer (b), the water supply step is performed by the predetermined program. Go to 40) to control the water supply and drainage drive (C) to supply water to the washing unit (2), and then go to the water level detection and heating step 41 to detect the water level supplied through the water level detection unit (D) Heater (E) The heater 4 is driven to supply water to a predetermined water level while heating the washing water supplied to a predetermined temperature.

In this way, while the water level is sensed and the water is being heated while the water is being supplied, the microcomputer (b) goes to the water supply completion judgment stage 42 and determines whether the water supply is completed at the predetermined level through the water level detection unit d. When the water supply is completed, the water supply is completed, and when the water supply is completed, the microcomputer (b) goes to the washing step 43 and controls the motor 5 of the motor unit e and the pump 7 of the pump unit bar respectively. By rotating the spray nozzle 3 and sucking the heated washing water and pumping it to the rotating spray nozzle 3, the spray nozzle 3 sprays the washing water onto the dish while rotating by the motor 5. In this case, the dish washing is performed. In this case, dishes having different degrees of contamination are already placed on the shelf 1 so that the washing water sprayed by the rotating spray nozzle 3 is the same. Can not be obtained.

Therefore, the microcomputer (b) goes to the contamination position determination step 44 and controls the position detection means 6 of the position detection unit (h) to rotate the injection nozzle (3) by the motor (5) the current degree of contamination It is determined whether or not the dishes are partitioned and placed on which table, where the position detected by the spray nozzle 3 is a predetermined angle of the upper surface of the position sensing means 6, that is, the mutter 5. A fixed contact portion which opens and shorts in a range, and a rotary contact portion is formed on a rotation axis of the motor 5 so that the rotation contact portion opens and shorts with the fixed contact portion when the motor 5 rotates. ) And the injection position of the injection nozzle (3) in conjunction with.

Therefore, when it is determined in the contamination position determination step 44 that the injection nozzle 3 is detected as being in a highly polluted position, the microcomputer (b) goes to the motor rotation low speed step 45 and the motor of the motor part (bar). By controlling the rotation speed to rotate at a low speed by controlling (5), the spray nozzle 3 interlocked with the low speed rotates at a low speed to spray the washing water pumped from the pump 7 to the highly contaminated dishes. Dish washing is performed while receiving the injection amount, on the other hand, if it is determined that the injection nozzle 3 is in a low pollution position as determined by the contamination position determination step 44, the microcomputer (b) rotates the motor low speed step ( 45 to control the motor 5 of the motor part (bar) to control the rotational speed to rotate at a constant speed, so that the spray nozzle 3 linked thereto is also pumped at the pump 7 while rotating at a constant speed. The washing water being pinged is sprayed onto the dishware with low contamination, and the dish washing is performed at the normal spray amount.

As described above, the microcomputer (b) goes to the washing completion determination step 47 to determine whether a predetermined washing time is completed while the spraying amount is changed depending on the position of the spraying nozzle 3, and at this time, the washing time is completed. If not, the rotational position of the injection nozzle 3 is sensed from the washing step 43, and the dish washing is repeatedly performed while varying the injection amount by adjusting the rotational speed of the injection nozzle according to the detected rotational position detection. Subsequently, when the washing is completed, the next administration is performed.

As described above, according to the present invention, the dishes to be washed at the time of dish washing are divided and placed on the shelves according to the degree of contamination, and the spray nozzles for spraying the washing water onto the dishes are washed by rotating with a separate motor. Depending on the degree, by rotating the spray nozzle at a slow or normal speed to the washing by changing the injection amount, to provide a clean cleaning effect within a predetermined cleaning time.
