본 고안은 세탁기에 관한 것으로, 특히 세탁시 세제 투입량을 감지하여 적당한 세제가 투입될 수 있도록 하는 세탁기의 세제 투입량 감지장치에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a detergent input amount sensing device of a washing machine to detect a detergent input amount during washing so that a suitable detergent can be input.

종래에는 제1도에 도시된 바와같이 세탁기(1)의 상부면에 세제를 넣을 수 있는 세제 투입구(2)를 형성하여 이 세제 투입구(2)를 통하여 세제를 넣으면, 세탁조(3)내로 세제가 흘러들어가도록 이루어져 있었다.Conventionally, as shown in FIG. 1, when a detergent inlet 2 is formed in the upper surface of the washing machine 1, and detergent is inserted through the detergent inlet 2, detergent is introduced into the washing tank 3. It was made to flow in.

그러나, 종래에는 세탁중에 사용자가 세제를 넣을 때 세탁물의 양에 따라 적당량의 세제를 넣어야 하나, 적당량의 세제를 넣을 수있는 기준이 없어 눈짐작으로 세제를 넣기 때문에 과다하게 세제를 투입시키게 되거나 또는 부족하게 세제를 투입시키게 되는 문제가 있고, 이에 따라 과다한 세제 사용에 의한 환경오염을 유발할 뿐만 아니라 부족한 세제 투입에 따른 미비한 세탁을 수행하게 되는 문제가 있다.However, conventionally, when a user adds detergent during washing, an appropriate amount of detergent should be put in accordance with the amount of laundry, but since there is no standard for putting an appropriate amount of detergent, the detergent is added as an eye guess. There is a problem that the detergent is added, thereby causing an environmental pollution by excessive use of the detergent, there is a problem to perform a poor washing due to insufficient detergent input.

본 고안은 이와같은 종래의 문제점을 해결하기 위하여 안출한 것으로 , 중량센서를 사용하여 세탁물의 양을 감지함으로써 세탁물량에 따른 적정량의 세제만 자동적으로 투입되게 하는 세탁기의 세제 투입량 감지장치를 제공하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, and provides a detergent input amount detection device of the washing machine to automatically input only the appropriate amount of detergent according to the amount of laundry by detecting the amount of laundry using a weight sensor. There is a purpose.

또한, 본 고안은 세탁물량에 따른 적정량의 세제를 사용하여 환경오염을 방지 하고, 최적의 세탁 효율을 증대시킬 수 있도록 하는데 또다른 목적이 있다. 이와같은 목적을 달성하기 위한 본 고안은, 세제를 넣기 위한 세제 투입구와, 상기 세제 투입구 밑부분에 이동가능하게 결합되어 세제를 이송시키기 위한 스크류와, 마이컴의 제어에 따라 동작하여 상기 스크류를 회전시키는 모터와, 상기 스크류를 통해 이송된 세제가 모여지는 다이아후램과, 상기 다이아후램에 연결되어 물을 공급 하기 위한 급수구와, 상기 다이아후램의 밑부분에 연결되어 세제량에 따라 이동되는 코어와, 상기 코어 밑면에 설치된 탄성력을 가진 스프링과, 상기 코어의 이동에 따라 자속이 변하는 코일과, 상기 코일에 의해 변하는 자속을 발진회로로 전달하는 단자와, 상기 발진회로에 의해 변한 주파수와 초기 감지된 주파수를 비교하여 포량에 따른 세제가 투입되도록 제어하는 마이컴을 포함하여 구성함을 특징으로 한다.In addition, the present invention has another object to prevent the environmental pollution by using the appropriate amount of detergent according to the amount of laundry, and to increase the optimal washing efficiency. The present invention for achieving the above object, the detergent inlet for the detergent, a screw for transferring the detergent is coupled to the bottom of the detergent inlet movably, and operating under the control of the microcomputer to rotate the screw A motor, a diaphragm in which detergent delivered through the screw is collected, a water supply port connected to the diaphragm for supplying water, a core connected to a lower portion of the diaphragm and moved according to a detergent amount, and the core A spring having elastic force installed on the bottom, a coil whose magnetic flux changes as the core moves, a terminal which transmits the magnetic flux that is changed by the coil to an oscillation circuit, and a frequency changed by the oscillation circuit and an initially sensed frequency are compared. It characterized in that it comprises a microcomputer to control the detergent to be injected according to the amount.

이하에서 본 고안 세탁기의 세제 투입량 감지장치의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the detergent input amount detection device of the subject innovation was described in detail as follows.

제2도는 본 고안의 세제를 투입시키기 위한 구성을 단면으로 나타낸 것으로 세제를 넣기 위한 세제 투입구(10)와, 상기 세제 투입구(10) 밑부분에 이동가능하게 결합되어 투입되는 세제를 이송시키기 위한 세제 이송수단인 스크류(7)와, 마이컴의 제어에 따라 동작하여 스크류(7)를 회자시키는 모터(12)와, 상기 스크류(11)를 통해 이송된 세제를 모아 중량을 감지하기 위한 다이아후램(DIAPHRAGM)(13)과, 상기 다이아 후램(13)에 연결되어 물을 공급하기 위한 급수구(14)와, 상기 다이아후램(13)의 밑 부분에 설치되어 세제의 양에 따라 이동되는 코어(15)와, 상기 코어(15)의 밑면에 설치된 탄성력을 가진 스프링(16)과, 상기 코어(15)의 이동에 따라 자속이 변하는 코일(17)과, 상기 코일(17)에 의해 변하는 자속을 발진회로로 전하기 위한 단자(18)로 구성된 것이다 .2 is a cross-sectional view showing a configuration for injecting the detergent of the present invention as a detergent inlet (10) for the detergent, detergent for transporting the detergent is movably coupled to the bottom of the detergent inlet (10) Screw (7) which is a conveying means, a motor (12) that operates under the control of the microcomputer to rotate the screw (7), and a diaphragm (DAPHRAGM) for sensing the weight by collecting the detergent transferred through the screw (11) 13, a water supply port 14 connected to the diaphragm 13 for supplying water, and a core 15 installed at a lower portion of the diaphragm 13 and moved according to the amount of detergent. And an oscillating circuit for generating a spring 16 having an elastic force provided on the bottom surface of the core 15, a coil 17 whose magnetic flux changes as the core 15 moves, and a magnetic flux that is changed by the coil 17. It consists of a terminal (18) for conveying to.

제3도는 본 고안의 회로도로 상기 단자(18)로 부터의 출력을 입력받아 자속의 변화에 따른 코일과 콘덴서의 발진에 의한 주파수 값을 출력시키는 공지의 발진회로(19)이다 .3 is a circuit diagram of the present invention, which receives the output from the terminal 18 and outputs a frequency value by oscillation of a coil and a capacitor according to a change in magnetic flux.

이와같이 구성된 본 고안은 세탁시 세탁기에 전원을 인가하면, 제3도와 같은 회로도의 출력단으로 초기 주파수가 출력되어 마이컴(20)에서 이러한 초기 주파수를 감지하게 된다(제4도의 S1, S2단계). 또한, 세탁조내에 넣어진 세탁물의 포량을 센싱하여 그 포량에 따른 수위를 결정하게 되며, 전원 인가에 따라 동기 모터(12)가 구동하여 스크류(7)가 회전하게 됨으로써 세제 투입구(10)에 넣어져 있던 세제가 스크류(11)를 통해 다이아후램(13) 으로 이송하게 된다(제4도의 S3-S5단계). 따라서, 다이아후램(13)에 유입되는 동시에 다이아후램(13)의 밑부분에 결합 되어 있는 코어(15)도 밑으로 이동하므로 상기 코어(15)의 주위에 감겨져 있는 코일 (17)의 자속이 변하게 되며, 이때 코어(15)밑에 설치된 스프링(16)이 압축된다. 이와같이 다이아후램(13)에 넣어지는 세제량에 따라 코어(15)가 이동하여 코일(17)의 자속이 변하면 단자(18)에 연결된 제3도와 같은 발진회로(19)의 구성에 의하여, 즉, 코일과 콘덴서의 발진에 의한 주파수 값이 변하게 되고, 이렇게 변하는 주파수값을 마이컴(20)에서 입력받아 초기 주파수 값과 비교하여 세탁조의 수위에 맞는 세제 중량인가를 판별한다(Se 단계). 만일, 다이아후램(13)에 넣어진 세제량이 적으면 수위에 맞는 세제중량이 아닌 것으로 판별하여 계속해서 세제 투입을 실시하도록 마이컴(20)에서 제어하게 된다. 또한, 수위에 맞는 세제 중량인 것으로 판별되면 마이컴(20)에서 동기 모터 (12)의 동작을 정지시키도록 제어하여 다이아후램(13)으로의 세제 투입이 중단된다 (S7. 단계). 세제 투입이 중단되면 마이컴(20)에서 급수가 진행되도록 제어하여 급수구 (14)를 통하여 급수가 이루어지므로 다이아후램(13)에 넣어진 세제가 물과 함께 혼합되어 세탁조로 유입된다(S8단계). 이렇게 세탁조로 세제가 혼합된 물이 유입되면 마이컴(20)에서는 포량에 맞는 수위인가를 판별하여 포량에 맞는 수위가 아니면 계속하여 급수를 수행하도록 제어 한다(S9단계 ) . 만일, 포량에 맞는 수위가 되면 마이컴(20)에서는 세탁과 헹굼 및 탈수를 순차적으로 수행하도록 제어하게 되며, 모든 행정이 끝나면 세탁이 완료되는 것이다 (S10-S13단계 ) . 이상에서 설명한 바와같이 본 고안은 포량에 따라 적당한 세제가 투입되도록 자동적으로 제어하여 종래의 과다 세제 사용에 의한 환경오염을 방지할 수 있음은 물론, 부족한 세제 투입에 따른 미비한 세탁수행을 방지할 수 있으며, 눈짐작으로 세제를 투입시킬 필요가 없으므로 세탁시 더욱 편의를 가져올 수 있는 효과가 있다.In the present invention configured as described above, when power is applied to the washing machine during washing, the initial frequency is output to the output terminal of the circuit diagram as shown in FIG. 3 and the microcomputer 20 detects the initial frequency (step S 1 and S 2 of FIG. 4). . In addition, by sensing the amount of the laundry contained in the washing tank to determine the water level according to the amount, the synchronous motor 12 is driven by the power is applied to the screw 7 is rotated to be put into the detergent inlet 10 The detergent was sent to the diaphragm 13 through the screw 11 (step S 3- S 5 of FIG. 4). Accordingly, the magnetic flux of the coil 17 wound around the core 15 changes because the core 15 which flows into the diaphragm 13 and is coupled to the bottom of the diaphragm 13 also moves downward. At this time, the spring 16 installed under the core 15 is compressed. When the core 15 moves according to the amount of detergent put into the diaphragm 13 and the magnetic flux of the coil 17 changes, the configuration of the oscillation circuit 19 as shown in FIG. 3 connected to the terminal 18 is used. The frequency value due to the oscillation of the condenser is changed, and the frequency value thus input is received from the microcomputer 20 and compared with the initial frequency value to determine whether the detergent weight is appropriate for the level of the washing tank (Se step). If the amount of detergent put into the diaphragm 13 is small, it is determined that it is not the detergent weight suitable for the water level, and the microcomputer 20 is controlled to continuously perform the detergent injection. Further, when it is determined that the detergent by weight for the water level is controlled so as to stop the operation of the synchronous motor 12 in the microcomputer 20 stops the detergent dispenser to the diamine huraem (13) (S 7. Phase). When the detergent is stopped, the water supply is controlled through the water supply port 14 by controlling the water supply to proceed from the microcomputer 20, and the detergent put into the diaphragm 13 is mixed with the water and introduced into the washing tank (S 8 step). ). When the water mixed with detergent is introduced into the washing tank as described above, the microcomputer 20 determines whether the water level is suitable for the quantity of water and controls the water supply to continue if the water level is not suitable for the quantity of water (S 9 ). If the water level is appropriate for the quantity, the microcomputer 20 controls washing and rinsing and dehydration to be performed sequentially, and washing is completed after all the strokes (S 10 -S 13 steps). As described above, the present invention can automatically prevent the appropriate detergent to be added according to the amount of water, thereby preventing environmental pollution caused by the use of conventional excess detergent, as well as preventing inadequate washing performance due to insufficient detergent input. As there is no need to put detergent into the eye, there is an effect that can bring more convenience when washing.
