CONSTITUTION: When all kinds of washing data is input through a washing operation input unit(1) after a user feeds power to a washing machine, a microcomputer(3) of the washing machine performs the load sensing at the beginning of washing by controlling a motor driving unit(4) and a load sensing unit(2) and accordingly measures the amount of washing load input into a washing tub. If the load sensing is completed, and the amount of washing load is measured, the level of washing water is decided, and water supplying is started based on the water level. In addition, as the water supplying is completed, washing-draining-rinsing-draining process is performed.

Description

세탁기의 탈수시간 제어방법How to control the dehydration time of the washing machine

본 발명은 세탁기의 탈수시간 제어방법에 관한 것으로서, 특히 탈수행정의 초기에 세탁기 마이컴이 모터 가속시 최고 RPM(Revolution Per Minute)까지 도달하는 시간을 체크한 후 설정치와 비교 판단하여 설정치보다 적으면 기존에 설정된 본 탈수시간을 단축시키고, 설정치보다 많이 걸리면 기존에 설정된 본 탈수시간을 연장시킴으로써 세탁물의 양에 따라 탈수시간을 적정하게 보상시킬 수 있도록 한 것이다.The present invention relates to a method for controlling the dehydration time of a washing machine. In particular, when the washing machine microcomputer reaches the maximum RPM (Revolution Per Minute) when the motor is accelerated at the initial stage of the dehydrating stroke, it is determined by comparing with the set value. To reduce the dehydration time set in the, and if it takes more than the set value is to extend the existing dewatering time set in advance to properly compensate for the dehydration time according to the amount of laundry.

일반적으로 세탁기로 세탁시에는 도 1과 같은 과정을 거쳐 세탁을 수행하게 되는데 특히, 탈수행정을 수행할 때에는 소정 시간과 횟수로 발란스탈수를 한 후 곧이어서 본 탈수를 하도록 되어 있다. 따라서, 통상적으로 탈수시간이라 함은 상기의 발란스 탈수와 본탈수를 수행하는데 걸리는 총시간을 칭한다.In general, when washing with a washing machine to perform the washing through the same process as in Fig. 1, in particular, when performing the dehydration administration balance dehydration for a predetermined time and number of times, after this dehydration. Therefore, the dehydration time usually refers to the total time taken to perform the balance dehydration and the main dehydration.

종래 세탁기의 탈수시간 제어장치는 세탁조내의 빛투과율을 검출하는 빛투과율 검출부와, 상기 빛투과율 검출부를 구동시키는 구동부와, 상기 빛투과율 검출부로 검출한 신호에 따라 세탁기의 동작상태를 제어하는 마이컴으로 구성되어 있다.Conventional dehydration time control device of the washing machine comprises a light transmittance detection unit for detecting the light transmittance in the washing tank, a drive unit for driving the light transmittance detection unit, and a microcomputer for controlling the operation state of the washing machine according to the signal detected by the light transmittance detection unit It is.

상기와 같은 구성을 갖는 탈수시간 제어시스템은 세탁조내의 세탁수가 배수호스로 배출될 때 빛투과율 검출부가 배수되는 세탁수에 빛을 검출시키고, 그 투과한 빛의 량을 다시 빛투과율 검출부에서 받아 마이컴에 입력되므로써 마이컴은 기설정된 빛투과율 검출부의 기준값과 현재 검출되는 빛투과율 검출부위 빛의 투과량을 비교하여 탈수행정에서 탈수정도가 상기한 기준치에 도달하였을 때 탈수행정을 제어하여 탈수시간을 조절하게 되어 있었다.The dehydration time control system having the above configuration detects light in the wash water drained by the light transmittance detection unit when the wash water in the washing tank is discharged to the drain hose, and receives the amount of light transmitted from the light transmittance detector again. By inputting, the microcomputer compares the reference value of the preset light transmittance detection unit with the amount of light transmitted at the currently detected light transmittance detection site, and controls the dehydration time when the degree of dehydration reaches the reference value described above. .

그러나, 종래 세탁기의 탈수시간 제어시스템은 탈수행정중에서 세탁물의 양과 질을 고려하지 않고 어느 일정기준치에 도달하였을 때 빛투과율 검출부가 탈수정도를 확인하여 탈수시간을 제어하기 때문에 세탁물의 양이 많을 때에는 적절한 탈수시간을 벗어나 무리한 탈수시간을 행함으로써 전력낭비 및 세탁물의 손상을 가져올 수 있었고 세탁물의 양이 적을 때에는 빛투과율 검출부의 기준치까지 도달하는데 너무 빠르기 때문에 적절한 탈수시간의 보상이 이루어지지 않았디.However, the dehydration time control system of a conventional washing machine does not consider the quantity and quality of laundry in the dehydration operation. When a certain reference value is reached, the light transmittance detector checks the degree of dehydration to control the dehydration time. Excessive dehydration time out of the dehydration time could lead to waste of power and damage to the laundry. When the amount of the laundry is small, it is too fast to reach the threshold of the light transmittance detector.

한편, 세탁기로 세탁할 때에는 도 1과 같은 순서로 세탁행정을 진행하게 되는데 특히, 탈수행정시 도 2에 도시된 바와같이, 탈수가 시작되면 미리 설정된 몇단계를 거쳐 최고 RPM까지 모터가 스피드 업되는 가속단계(Ⅰ)와, 상기 가속단계(Ⅰ)를 거쳐 일정한 RPM값을 유지하는 본탈수 단계(Ⅱ)로 나눌 수 있는데 이때의 총탈수시간은 소비자가 직접 선택하거나 퍼지코스에 의해 자동 설정될 수 있다.On the other hand, when washing with a washing machine proceeds the washing administration in the same order as in Figure 1, in particular, as shown in Figure 2 during the dehydration stroke, when dehydration is started, the motor speeds up to the highest RPM through a predetermined number of steps Acceleration step (I) and the main dehydration step (II) to maintain a constant RPM value through the acceleration step (I) can be divided into a total dehydration time can be selected directly by the consumer or automatically set by the fuzzy course have.

통상, 퍼지코스에 있어서 탈수시간은 세탁부하에 상관없이 가속단계(Ⅰ)와 본탈수 단계(Ⅱ)의 합으로 산정되므로 비효율적인 경우가 많다. 즉, 예를 들어 총 탈수시간을 5분으로 선정해도 세탁부하가 많게 되면 가속단계(Ⅰ) 구간에서 시간을 많이 잡아먹게 되므로 본탈수 단계(Ⅱ) 구간에서의 시간이 실질적으로 줄게 되어 실제 탈수시간이 단축되는 현상이 발생한다.In general, the dehydration time in the purge course is inefficient because it is calculated as the sum of the acceleration stage (I) and the main dehydration stage (II) regardless of the washing load. That is, for example, even if the total dehydration time is selected as 5 minutes, if the laundry load becomes large, it takes a lot of time in the acceleration stage (I) section, so the time in the main dehydration stage (II) section is substantially reduced. This shortening phenomenon occurs.

다시말해, 탈수성능에 실제로 영향을 미치는 것은 스피드 업된 상태인 본 탈수 단계(Ⅱ)이므로 세탁물의 양에 따라 탈수시간을 보상시켜줄 필요성이 있는 것이다.In other words, the dehydration step (II), which is in the speed-up state, actually affects the dehydration performance, and thus it is necessary to compensate the dehydration time according to the amount of laundry.

그러나, 위에서 설명한 바와같이 종래에는 세탁물의 양에 관계없이 탈수시간이 설정되기 때문에 탈수가 효율적으로 이루어지지 못하는 문제점이 있었다.However, as described above, there is a problem in that dehydration is not performed efficiently because the dehydration time is set regardless of the amount of laundry.

위와 같은 문제점을 해결하기 위하여 본 발명은 탈수행정의 초기에 세탁기 마이컴이 모터 가속시 최고 RPM 까지 도달하는 시간을 체크한 후 설정치와 비교 판단하여 설정치보다 적으면 기존에 설정된 본 탈수시간을 단축시키고, 설정치보다 많이 걸리면 기존에 설정된 본탈수시간을 연장시켜 세탁부하에 따라 탈수시간을 적정하게 보상시킬 수 있도록 함으로써 세탁물의 양에 따라 본탈수 시간을 효율적으로 보상할 수 있도록 한 세탁기의 탈수시간 제어방법을 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention checks the time at which the washing machine micom reaches the maximum RPM when the motor accelerates in the initial stage of the dehydration stroke, and then compares the set value with the set value to shorten the previously set dehydration time. If it takes longer than the set value, the dehydration time control method for washing machine can be efficiently compensated for the dehydration time according to the amount of laundry by extending the dehydration time set in advance to compensate for the dehydration time according to the washing load. The purpose is to provide.

그럼 지금부터 도 5의 흐름도를 중심으로 본 발명을 좀 더 상세히 설명하면 다음과 같다.Now, the present invention will be described in more detail with reference to the flowchart of FIG. 5 as follows.

즉, 본 흐름도는 세탁운전신호가 입력되면 로드센싱→급수→세탁→배수→헹굼→배수처리를 하는 단계(스텝100)와, 상기 단계가 모두 완료되면 발란스 탈수에서 탈수모터의 가속시 최고 RPM까지 도달하는데 걸리는 시간 TI를 체크하는 단계(스텝101)와, 상기 단계에서 TI가 체크되면 TI＞TK(실험에 의해 산출된 설정치)인지를 판단하는 단계(스텝102)와, 상기 단계에서 TI＞TK라고 판단되면 기존에 설정된 본탈수시간을 소정시간만큼 연장시켜 셋팅하는 단계(스텝103)와, 상기 단계에서 TI＞TK가 아니라고 판단되면 다시 TI=TK인지를 판단하는 단계(스텝104)와, 상기 단계에서 TI=TK라고 판단되면 본탈수시간을 기존에 설정된 본탈수시간과 동일하게 셋팅하는 단계(스텝105)와, 상기 단계에서 TI=TK가 아니라고 판단되면 기존에 설정된 본탈수시간을 소정시간만큼 단축하여 셋팅하는 단계(스텝106)와, 상기 셋팅과정이 완료되면 이에 따라 설정된 소정시간동안 본탈수를 실시하는 단계(스텝107)로 이루어져 있다.That is, this flowchart is a step of performing the load sensing → water supply → washing → drainage → rinsing → drainage treatment when the washing operation signal is input (step 100), and when the above steps are completed, the balance dewatering to the maximum RPM when the dehydration motor is accelerated. Checking the time T I taken to reach (step 101); determining whether T I > T K (the set value calculated by the experiment) if T I is checked in the step (step 102); and If it is determined that T I > T K in step (step 103) to extend the existing set dehydration time by a predetermined time, and if it is determined in the step not T I > T K again whether the T I = T K Determining step (step 104), and if it is determined that T I = T K in this step, setting the dehydration time to be equal to the previously set dehydration time (step 105), and in this step, T I = T K If it is not determined that the previous dehydration time The step of setting the speed by a constant time (step 106) and, when the setting process is finished is made to a step (step 107) to conduct the dehydration during this predetermined time is set according.

이와같은 단계를 갖는 본 발명의 처리과정을 좀 더 상세히 살펴보면 먼저, 사용자가 세탁기에 전원을 인가시킨 후 세탁운전 입력부(1)를 통해 각종 세탁정보를 입력시키면 세탁기 마이컴(3)은 모터구동부(4), 부하감지부(2) 등을 제어하여 세탁초기에 로드센싱을 수행시키고 이에 따라서 세탁조에 투입된 세탁부하량을 측정하게 된다.Looking at the process of the present invention having such a step in more detail, first, after the user applies power to the washing machine and inputs various washing information through the washing operation input unit 1, the washing machine microcomputer 3 is the motor drive unit 4 ), The load sensing unit 2 is controlled to perform load sensing at the beginning of the washing process, and thus the washing load input to the washing tank is measured.

상기의 로드센싱이 완료되어 세탁 부하량이 측정되면 이에 따라 세탁수위가 결정되고 이에 맞게 급수가 시작된다. 또한, 급수가 완료됨에 따라 일련의 세탁과정인 세탁→배수→헹굼→배수 처리과정을 수행하게 된다(스텝100).When the load sensing is completed and the washing load is measured, the washing level is determined accordingly, and water supply is started accordingly. In addition, as the water supply is completed, a series of washing processes, such as washing → draining → rinsing → draining, are performed (step 100).

상기 단계가 모두 완료되면 세탁기 마이컴(3)은 다시 모터구동부(4)에 제어신호를 보내 탈수모터를 기동시켜 발란스 탈수를 수행하게 되는데 이때, 탈수모터의 가속시 최고 RPM까지 도달하는데 걸리는 시간 TI을 체크하게 된다(스텝101).When all of the above steps are completed, the washing machine microcomputer 3 sends a control signal to the motor driving unit 4 again to start the dehydration motor to perform the balance dehydration. In this case, the time taken to reach the maximum RPM when the dehydration motor is accelerated T I. Is checked (step 101).

또한, 상기 단계에서 TI가 체크되면 세탁기 마이컴(3)은 TI＞TK인지를 판단하게 되는데(스텝102) 이경우, TK값은 실험에 의해 산출된 설정치로 세탁기 용량에 따라 다르게 설정된다. 설정치의 예를 들면, 10Kg 세탁기는 2분, 8Kg 세탁기는 1분 30초, 5Kg 세탁기는 1분으로 각각 설정할 수 있다.In addition, if T I is checked in the above step, the washing machine microcomputer 3 determines whether T I > T K (step 102). In this case, the T K value is a set value calculated by the experiment and is set differently according to the washing machine capacity. . For example, the 10 Kg washing machine can be set to 2 minutes, the 8 Kg washing machine to 1 minute and 30 seconds, and the 5 Kg washing machine to 1 minute.

또한, 상기 단계에서 TI＞TK라고 판단되면 세탁기 마이컴(3)은 기존에 설정된 본탈수시간을 소정시간만큼 연장시켜 셋팅시킨다(스텝103).In addition, when it is determined in the step that T I > T K , the washing machine microcomputer 3 extends and sets the previously set main dehydration time by a predetermined time (step 103).

그러나, 상기 단계에서 TI＞TK가 아니라고 판단되면 세탁기 마이컴(3)은 다시 TI=TK인지를 판단하게 되는데(스텝104) 이경우, TI=TK라고 판단되면 본탈수시간을 기존에 설정된 본탈수시간과 동일하게 셋팅시킨다(스텝105).However, if it is determined that T I > T K in the above step, the washing machine microcomputer 3 again determines whether T I = T K (step 104). In this case, if it is determined that T I = T K , the original dehydration time is determined. The setting is equal to the main dehydration time set in step S105.

또한, 상기 단계에서 TI=TK가 아니라고 판단되면 세탁기 마이컴(3)은 기존에 설정된 본탈수시간을 소정시간만큼 단축하여 셋팅시킨다(스텝106). 상기 셋팅과정이 완료되면 이에 따라서 설정된 소정시간동안 본탈수가 실시된다(스텝107).In addition, if it is determined in the step that T I = T K , the washing machine microcomputer 3 shortens and sets the previously set main dehydration time by a predetermined time (step 106). When the setting process is completed, main dehydration is performed for a predetermined time set accordingly (step 107).

위와같이 본 발명에 의한 세탁기의 탈수시간 제어방법은 탈수행정의 초기에 세탁기 마이컴(3)이 모터 가속시 최고 RPM 까지 도달하는 시간을 체크한 후 설정치와 비교 판단하여 설정치보다 적으면 기존에 설정된 본탈수시간을 단축시키고, 설정치보다 많이 걸리면 기존에 설정된 본 탈수시간을 연장시켜 세탁부하에 따라 탈수시간을 적정하게 보상시킬 수 있도록 함으로써 세탁물의 양에 따라 본탈수시간을 효율적으로 보상할 수 있다.Dehydration time control method of the washing machine according to the present invention as described above checks the time to reach the maximum RPM when the washing machine microcomputer (3) at the initial stage of the dehydration stroke and then compares with the set value is less than the set value if the existing set If the dehydration time is shortened and it takes more than the set value, the dehydration time can be efficiently compensated according to the amount of laundry by extending the present dehydration time to properly compensate the dehydration time according to the washing load.
