Description

세탁기의 유연제 투입방법How to Put Softener in Washing Machine

본 발명은 세탁기의 유연제 투입방법에 관한 것으로서, 특히 세탁행정중 마지막 헹굼행정에서 투입되는 유연제를 세탁수의 급수완료후 헹굼시에도 시간부족없이 원할하게 투입할 수 있도록 유연제의 투입시간간격을 좁혀 셋팅시킴으로써 마지막 헹굼시 급수가 완료되어 유연제의 투입시간이 부족할지라도 유연제가 적절하게 투입될 수 있도록 한 것이다.The present invention relates to a softening agent input method of the washing machine, and in particular, setting the narrowing interval of the softening agent so that the softening agent that is added in the last rinsing stroke of the washing stroke can be smoothly added even when the rinsing after the completion of the water supply of the wash water. This is to ensure that the softener is properly added even if the water supply is completed at the last rinse and the softener input time is insufficient.

일반적으로 세탁기로 세탁시 세탁물의 정전기 방지 및 부드러움을 원형상태로 유지시켜주기 위해 헹굼행정시 유연제(린스)가 세탁물량에 상응하여 투입되었는데 종래에는 헹굼시 마지막 헹굼에서 급수를 시작함과 동시에 33초 오프, 7초 온간격으로 6회에 걸쳐 유연제투입밸브를 통해 세탁조에 유연제가 투입되었다.In general, in order to maintain the antistatic and softness of the laundry in a circular state when washing with a washing machine, a softener (rinse) was added in correspondence with the amount of laundry during the rinsing cycle. The softener was put into the washing tank through the softener inlet valve six times at intervals of 7 seconds on and off.

그러나, 종래에는 행굼행정시 급수가 완료된 상태에서 헹굼 1회만을 진행할 경우에 소요시간이 대략 3분 정도이기 때문에 6회의 유연제 투입이 완료되기에는 시간이 부족하였다. 따라서, 헹굼시 유연제가 충분히 투입되지 못해 정전기 방지 및 세탁물의 부드러움을 원형상태로 유지시켜주는 충분한 효과를 내지 못하였고, 유연제가 일정량이상 투입되지 않아 남게 되면 굳게 되어 이후의 유연제 투입에 문제를 일으키게 되었다.However, in the related art, when the rinsing process is performed only once in a state where water supply is completed during the rinsing cycle, the time required for the rinsing is about 3 minutes. Therefore, when the rinse was not added enough softening agent did not have enough effect to keep the antistatic and the softness of the laundry in a circular state, and if the softening agent is not added in a certain amount, it is hardened to cause problems in the subsequent softener input. .

위와 같은 문제점을 해결하기 위하여 본 발명은 세탁행정중 마지막 헹굼행정에서 투입되는 유연제를 세탁수의 급수완료후 헹굼시에도 시간부족없이 원할하게 투입할 수 있도록 유연제의 투입시간간격을 좁혀 셋팅시킴으로써 마지막 헹굼시 급수가 완료되어 유연제 투입시간이 부족할지라도 유연제가 적절히 투입되어 정전기 방지 및 세탁물의 부드러움을 원형상태로 유지시켜주는 효과를 충분히 거둘 수 있도록 한 세탁기의 유연제 투입방법을 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention rinsing the last rinsing time by narrowing the setting time interval of the softening agent so that the softening agent introduced in the last rinsing stroke of the washing administration can be smoothly added without lapse of time even after rinsing after the water supply of the washing water is completed. The purpose of the present invention is to provide a method of adding a softener in a washing machine, so that even if the water supply is completed and the softener input time is insufficient, the softener is properly added to sufficiently prevent the static electricity and the softness of the laundry.

즉, 본 흐름도는 초기에 로드센싱→급수→세탁을 실시하는 단계(스텝100, 스텝101, 스텝102)와, 상기의 세탁과정이 완료되었는지 여부를 판단하는 단계(스텝103)와, 상기 단계에서 세탁이 완료되었다고 판단되면 헹굼을 실시하여 이번 헹굼이 마지막 헹굼인지 여부를 체크하는 단계(스텝105)와, 상기 단계에서 마지막 헹굼이 아닌 것으로 판단되면 계속 헹굼동작을 실시하고(스텝104) 상기 단계에서 마지막 헹굼으로 판단되면 급수여부가 완료되었는지를 판단하는 단계(스텝106)와, 상기 단계에서 급수가 완료되었다고 판단되면 7초 온, 23초 오프 간격으로 유연제투입밸브를 온/오프시켜 유연제를 투입하는 단계(스텝107)와, 상기 단계에서 계속 급수중이면 7초 온, 33초 오프 간격으로 유연제투입밸브를 온/오프시켜 유연제를 투입하는 단계(스텝108)와, 상기 단계에서 유연제가 소정 시간 투입하고난 후 마지막 헹굼을 실시하는 단계(스텝110)로 이루어지게 된다.In other words, the flowchart shows the steps of initially performing load sensing → water supply → washing (step 100, step 101, step 102), determining whether the washing process is completed (step 103), and in the step When it is determined that washing is completed, a rinse is performed to check whether this rinsing is the last rinse (step 105), and if it is determined that the washing is not the last rinsing in this step, the rinsing operation is continued (step 104). If it is determined that the last rinsing step (step 106) to determine whether the water supply is complete, and if it is determined that the water supply is completed in the above step to turn on / off the softener inlet valve at 7 seconds on, 23 seconds off interval to inject the softener Step (step 107), and if the water is continuously supplied in the above step, turning on / off the softener injection valve at 7 second on and 33 second off intervals to inject the softener (step 108); Standing the softener will be written to the step (step 110) to perform a final rinse after the predetermined time is supplied.

이와같이 단계를 갖는 본 발명의 처리과정을 좀 더 상세히 설명하면 다음과 같다.As described above in more detail the process of the present invention having the steps as follows.

먼저, 사용자가 세탁기에 전원을 인가시킨 후 세탁기의 운전신호 입력부(1)를 통해 각종 세탁정보를 입력시키면 세탁기 마이콤(3)은 모터구동부(4)을 제어하여 세탁초기에 로드센싱을 수행시키고(스텝100), 이에 따라서 세탁조에 투입된 세탁부하량이 측정된다.First, when the user applies power to the washing machine and inputs various washing information through the driving signal input unit 1 of the washing machine, the washing machine micom 3 controls the motor driving unit 4 to perform the load sensing at the initial stage of washing. Step 100), accordingly, the washing load input to the washing tank is measured.

상기의 로드센싱이 완료되어 세탁 부하량이 측정되면 이에 따라 세탁수위가 결정되고 이에 맞게 급수가 시작된다(스텝101). 또한, 급수가 완료됨에 따라 본격적인 세탁이 실시되는데(스텝102) 이 경우 세탁기 마이컴(3)은 세탁시간을 체크하여 세탁이 완료되었는지 여부를 판단하게 된다(스텝103). 이때 세탁이 완료되었다고 판단되면 이번 헹굼이 마지막 헹굼인가 여부를 스텝105에서 판단한다.When the load sensing is completed and the washing load is measured, the washing level is determined accordingly, and water supply is started accordingly (step 101). In addition, as the water supply is completed, full-scale washing is performed (step 102). In this case, the washing machine microcomputer 3 checks the washing time to determine whether the washing is completed (step 103). If it is determined that washing is completed at this time, it is determined in step 105 whether the rinse is the last rinse.

여기에서 마지막 헹굼이 체크될 때까지 계속해서 헹굼을 실시한다.The rinse is continued until the last rinse is checked here.

유연제는 마지막 헹굼과정에서 투입되므로 마이컴(3)은 계속해서 이번 헹굼이 마지막 헹굼인지 여부를 판단하게 된다(스텝105).Since the softener is added during the last rinsing process, the microcomputer 3 continuously determines whether the rinse is the last rinse (step 105).

상기의 판단결과, 이번 헹굼이 마지막 헹굼이라고 판단되면 마이컴(3)은 계속해서 수위감지부(2)로부터 수위데이터를 인가받아 현재의 급수상태를 체크하고 급수가 완료되었는지 여부를 판단하게 되는데(스텝106) 이 경우, 급수가 완료되면 실제 유연제를 투입할 시간은 마지막 헹굼시간인 3분 정도밖에 없기 때문에 유연제를 좀 더 빠른 시간간격으로 투입시킬 필요가 있다.As a result of the above determination, if it is determined that this rinse is the last rinse, the microcomputer 3 continuously receives the water level data from the water level detection unit 2 to check the current water supply state and determine whether water supply is completed (step). 106) In this case, when the water supply is completed, it is necessary to add the softener at a faster time interval since the actual time of injecting the softener is only about 3 minutes, which is the last rinsing time.

따라서, 상기 단계에서 급수가 완료되었다고 판단되면 마이컴(3)은 유연제투입밸브 구동부(6)에 제어신호를 보내고 이에 따라 7초 온, 23초 오프간격으로 유연제투입밸브가 온/오프되면서 유연제가 좀 더 좁은 간격으로 투입된다(스텝107). 이와같이 유연제 투입을 7초 온, 23초 오프간격으로 하게 되면 급수가 끝나고 남은 헹굼시간 3분 동안에 유연제 6회 투입을 무난히 완료할 수 있다.Therefore, when it is determined that the water supply is completed in the above step, the microcomputer 3 sends a control signal to the softener injection valve driving unit 6, and accordingly, the softener input valve is turned on / off at 7 second on and 23 second off intervals. It is fed at a narrower interval (step 107). In this way, when the softener is added at an interval of 7 seconds on and 23 seconds off, 6 times of softeners can be completely completed in the remaining 3 minutes of rinsing time after the water supply is completed.

한편, 세탁기 마이컴(3)은 급수가 완료되지 않고 계속해서 급수중이면 유연제투입밸브 구동부(6)에 제어신호를 보내고 이에 따라 7초 온, 33초 오프간격으로 유연제투입밸브가 온/오프되면서 유연제가 보통때와 같이 투입된다(스텝108).On the other hand, the washing machine microcomputer 3 sends a control signal to the softener injection valve driving unit 6 when the water supply is not completed and continues to supply water, and thus the softener injection valve is turned on / off at 7 second on and 33 second off intervals. Is input as usual (step 108).

또한, 상기 마이컴(3)은 계속해서 유연제 투입이 완료되었다고 판단되면 계속해서 마지막 헹굼을 실시하게 된다(스텝110).In addition, the microcomputer 3 continuously performs the final rinsing when it is determined that the softening agent has been added (step 110).

위와같이 본 발명에 의한 세탁기의 유연제 투입방법은 세탁행정중 마지막 헹굼행정에서 투입되는 유연제를 세탁수의 급수완료후 헹굼시에도 시간부족없이 원할하게 투입할 수 있도록 유연제의 투입시간간격을 좁혀 셋팅시킴으로써 마지막 헹굼시 급수가 완료되어 유연제 투입시간이 부족할지라도 유연제가 적절히 투입되어 정전기 방지 및 세탁물의 부드러움을 원형상태로 유지시켜주는 효과를 충분히 거둘 수 있다.As described above, the softener input method of the washing machine according to the present invention sets the softener input in the last rinsing stroke of the washing machine by narrowing the input time interval of the softener so that the softener can be smoothly added even when rinsing after the water supply of the wash water is completed. When the last rinsing is completed, even if the water supply is completed and the softener input time is insufficient, the softener can be properly added to maintain the antistatic and softness of the laundry in a circular state.
