Description
본 발명은 세탁기의 발란스탈수제어방법에 관한 것으로, 특히 세탁완료후세탁중에 발생된 언발란스를 해제하기 위하여 발란스탈수를 진행함에 있어서 상기 언발란스 발생을 감지하는 안전스위치의 작동시간을 감지하여 이 감지된 안전스위치의 작동시간에 따라 발란스탈수시간을 제어하면서 발란스탈수를 할수 있도록 하는 세탁기의 발란스탈수제어방법에 관한 것이다.The present invention relates to a method for controlling the balance dewatering of a washing machine, and in particular, by detecting the operation time of a safety switch for detecting the occurrence of unbalance in the process of balancing dewatering in order to release the unbalance generated during washing after the completion of washing. The present invention relates to a balance dewatering control method of a washing machine that enables balance dewatering while controlling the balance dewatering time according to an operation time of a switch.
일반적으로 세탁이 완료되면 세탁중에 세탁수류마찰력에 의하여 세탁물간에 꼬임이 발생되고, 이 꼬임은 세탁조에 편심을 야기시켜 탈수시 저수조의 진동소음은 물론 세탁기에 손상을 주게 된다.In general, when the washing is completed, the twist between the laundry is generated by the washing water frictional force during the washing, this twist causes eccentricity in the washing tank, as well as damaging the washing machine as well as the vibration noise of the reservoir when dewatering.
그러므로 종래에는 상기 세탁중에 발생된 세탁물의 꼬임에 의한 언발란스를 감지하여 탈수시 세탁물의 꼬임에 의한 세탁조의 편심을 해제하기 위하여 안전스위치를 장착하여 상기 안전스위치의 작동상태로 언발란스를 감지하여 언발란스를 해제하도록 하였으나, 상기 안전스위치의 경우 언발란스감지는 상기 안전스위치의 작동시간에 관계없이 기설정된 소정의횟수 이하이면 그대로 탈수를 진행하고 상기 소정의 횟수 이상으로 작동하면서 비로서 언발란스로 감지하여 재급수하면서 언발란스를 해제하도록 되어 있었다.Therefore, in the related art, by detecting the unbalance caused by the twist of the laundry generated during the washing and releasing the eccentricity of the washing tank caused by the twist of the laundry during dehydration, a safety switch is mounted to detect the unbalance in the operating state of the safety switch to release the unbalance. However, in the case of the safety switch, the unbalance detection is carried out as it is, if it is less than a predetermined number of times regardless of the operation time of the safety switch. It was supposed to release.
이와같이 종래에는 언발란스를 안전스위치의 작동횟수만으로 감지하도록 되어 있어, 가령 세탁중에 세탁물의 꼬임 발생되어 언발란스가 발생되었음에 도 불구하고 안전스위치가 기설정된 소정의 횟수 이하로 작동하게 되는 경우 언발란스가 발생되지 않은 것으로 판단하여 탈수를 진행하게 되므로 상기 언발란스로 인한 진동소음을 야기시키면서 탈수가 진행될 뿐만 아니라, 탈수완료후 세탁물은 꼬임에 의하여 세탁물에 손상을 주게 되는 문제점을 가지게 되었다.Thus, conventionally, the unbalance is detected only by the number of operation of the safety switch. For example, even when the safety switch is operated less than a predetermined number of times, even if the unbalance occurs due to the twisting of the laundry during washing, the unbalance is not generated. Since dehydration proceeds as it is determined that the dehydration is not performed, dehydration proceeds while causing vibration noise due to the unbalance, and after the dehydration is completed, the laundry has a problem of damaging the laundry by twisting.
본 발명의 목적은 세탁완료후 발란스탈수시 안전스위치의 작동시간을 감지하여 이 안전스위치의 작동시간에 따라 발란스탈수시간을 제어하여 발란스탈수를 진행하도록 함으로써, 발란스탈수를 보다 효율적으로 할수 있도록 하는 데 있다.An object of the present invention is to detect the operation time of the safety switch when washing the dehydration after washing, to control the balance dehydration time according to the operation time of the safety switch to proceed with the balance dewater, to make the balance dewater more efficient have.
상기의 목적을 실현하기 위하여 본 발명은 초기화 상태에서 급수하고 세탁한후 발란스탈수시 안전스위치의 작동시간을 감지하여, 이 감지된 안전스위치의 작동시간이 기설정된 소정의 작동시간 이상인가를 판단하여 상기 감지된 안전스위치의 작동시간이 기설정된 소정의 작동시간 이하이면, 본 탈수를 진행하고, 상기 감지된 안전스위치의 작동시간이 기설정된 소정의 작동시간 이상으로 감지되면, 이 감지된 안전스위치의 작동시간에 따라 그에 해당하는 설정된 발란스탈수시간으로 발란스탈수를 진행하고 본탈수를 하도록 한 것을 특징으로 한다.In order to realize the above object, the present invention detects the operating time of the safety switch when balancing and dewatering water after washing and washing in an initial state, and determining whether the detected operating time of the safety switch is greater than or equal to a predetermined predetermined operating time. When the detected operating time of the safety switch is less than or equal to a predetermined predetermined operating time, the spin-drying is performed. When the detected operating time of the detected safety switch is detected to be greater than or equal to a predetermined predetermined operating time, According to the operating time, it is characterized in that the balance dehydration proceeds to the set balance dehydration time corresponding to the main dehydration.

At this time, if the operating time of the safety switch is not more than the predetermined operating time (100msec) is determined that no unbalance occurs because the laundry does not occur, go to the main dehydration step 38 to control the motor drive (e) Dewatering while rotating at high speed in one direction, on the other hand, if the detected operation time of the safety switch in the safety switch operation time determination step 37 is more than a predetermined predetermined operating time (100 msec), the laundry is twisted Judging from the microcomputer (b), go to the safety switch operation time selection judgment step 39, the operating time of the detected safety switch is 200msce, 300msec , 400msec or more is selected, and then go to the balance dewatering time setting step 40, and according to the safety switch operating time selected and determined in the safety switch operating time selection step 39, the corresponding dehydration time, that is 4 seconds temperature 3 seconds off, 5 seconds on 3 seconds off, 6 seconds on 3 seconds off.
이와같이 상기 감지된 안전스위치의 작동시간에 따라 탈수시간이 설정되면 이 설정된 탈수시간에 의하여 발란스탈수를 진행하게 되고, 상기 발란스탈수를 진행하는 동안 상기 마이콤(나)에서는 발란스탈수가 완료되었는가를 판단하게 되고, 이때 발란스탈수가 완료되었으면 본탈수(38)를 진행하게 되고 상기 발란스탈수가 완료되지 않았으면 상기 마이콤(나)에서는 상기 선택판단된 탈수시간으로 계속해서 발란스탈수를 진행하되, 상기 발란수탈수가 완료될때 까지 발란스탈수를 하게 되는 것이다.In this way, if the dehydration time is set according to the detected operating time of the safety switch, the balance dehydration proceeds according to the set dehydration time, and the microcomputer (b) determines whether the balance dehydration is completed during the balance dehydration. In this case, when the balance dehydration is completed, the main dehydration 38 is performed. If the balance dehydration is not completed, the microcomputer (b) continues the balance dehydration with the selected dehydration time, but the balance dehydration is performed. The balance is dehydrated until it is completed.
이상에서 설명한 바와같이 본 발명은 세탁완료후 발란스탈수시 안전스위치의 작동시간을 감지하여 이 안전스위치의 작동시간 즉 오프에서 온되는 시간에 따라 발란스탈수시간을 길게 제어하고, 이 제어된 발란스탈수시간으로 발란스탈수를 진행하도록 함으로써, 발란스탈수를 보다 효율적으로 할수 있는 효과를 제공하게 되는 것이다.As described above, the present invention detects the operation time of the safety switch when the balance is dehydrated after washing, and controls the balance dehydration time longer according to the operation time of the safety switch, that is, the time that is turned off. By advancing the balanced dewatering as described above, it is possible to provide the effect of making the balanced dewatering more efficient.
