Description

저주파 진동세탁기의 구동장치Low Frequency Vibratory Washing Machine

본발명은 저주파 진동세탁기의 구동장치에 관한 것으로서, 더욱 상세하게는 저주파 진동세탁기가 모터의 일방향 회전만으로도 효율적인 세탁 및 탈수기능을 수행할 수 있도록 한것이다.The present invention relates to a driving device of a low frequency vibration washing machine, and more particularly, to enable a low frequency vibration washing machine to perform an efficient washing and dehydration function only by one-way rotation of a motor.

일반적으로, 저주파 진동세탁기는 세탁조내에 있는 물과 세제 및 공기층으로 구성된 다상매질에 공진현상을 일으켜 이때 발생하는 다상매질내의 미소공기방울들의 공동화현상(Cavitation Phenomena)또는 비선형진동(Nonlinear Oscillation)에 의한 기계적 에너지와 세제에 의한 화학적인 작용에 의해 세탁 및 세척기능을 수행하게 된다.In general, a low frequency vibration washing machine causes resonance in a polyphase medium composed of water, detergent and an air layer in a washing tank, and mechanically caused by cavitation phenomena or nonlinear oscillation in the polyphase medium. The washing and washing functions are performed by chemical action by energy and detergent.

이를위해 종래의 저주파 진동세탁기는 제1도에 나타낸 바와같이, 물과 세제와 공기층으로 구성된 다상매질을 수용하는 세탁조(26)내의 하부에 리니어모터(27)의 구동축(28)이 관통하여 설치되고, 상기 세탁조(26)내의 구동축(28)상단에는 세탁조(26)내에 수용된 다상매질에 공진현상을 일으키는 저주파 발진용 진동자(19)가 설치되며, 상기 리니어모터(27)에는 변위진폭신호와 주파수신호를 보내는 신호발진부(29)와 신호를 증폭하여 가변시키는 신호증폭부(30)가 연결되고, 상기 세탁조(26)의 개방부에는 진동이 세탁조(26)밖으로 누설되지 않도록 밀폐판(31)이 설치되어 구성된다.To this end, as shown in FIG. 1, the conventional low frequency vibration washing machine is installed by driving the drive shaft 28 of the linear motor 27 through the lower part of the washing tank 26 containing a multiphase medium composed of water, detergent and air layer. In addition, a low frequency oscillator 19 is provided on the drive shaft 28 in the washing tank 26 to cause resonance in the multiphase medium accommodated in the washing tank 26. The linear motor 27 has a displacement amplitude signal and a frequency signal. The signal oscillation unit 29 for transmitting the signal and the signal amplification unit 30 for amplifying and varying the signal is connected, and the sealing plate 31 is installed in the opening of the washing tank 26 so that vibration does not leak out of the washing tank 26. It is configured.

따라서, 리니어모터(27)에 연결된 신호발진부(29) 및 신호증폭부(30)의 신호에 따라 리니어모터(27)를 구동시키게 되면, 세탁조(26)내의 구동축(28)상단에 설치된 저주파 발진용 진동자(19)가 발진을 하여 세탁조(26)내에있는 물과 세제 및 공기층으로 구성된 다상매질에 공진현상을 일으키게 되므로써, 이때 발생되는 미소공기방울들의 공동화현상 또는 비선형진동에 의한 기계적 에너지와 세제의 화학작용이 결합되어 세탁기능을 수행하게 된다.Therefore, when driving the linear motor 27 in accordance with the signal of the signal oscillator 29 and the signal amplifier 30 connected to the linear motor 27, for low frequency oscillation installed on the drive shaft 28 in the washing tank 26 The oscillator 19 oscillates and causes resonance in the multiphase medium composed of water, detergent and air layer in the washing tank 26, and thus mechanical energy and chemicals of detergent due to cavitation or non-linear vibration of micro air bubbles generated at this time. The action is combined to perform the washing function.

그러나, 이와같은 종래의 저주파 진동장치는 리니어모터(27) 이외에 세탁조(26)에 타이밍벨트(32)로서 연결되어 탈수시 세탁조(26)를 구동시키기 위한 별도의 탈수용모터(33)를 설치해서 사용해야 하므로 설치공간이 많이 소요된다.However, such a conventional low frequency vibration device is connected to the washing tank 26 as a timing belt 32 in addition to the linear motor 27, and installs a separate dewatering motor 33 for driving the washing tank 26 when dewatering. This requires a lot of installation space.

제2도는 본발명을 나타낸 종단면도이고 제3도는 제2도의 클러치 스프링을 나타낸 사시도이며, 제4도는 브레이크레버 및 브레이크밴드의 작동상태를 나타낸 원리도로서, 외조(1)의 하부에 장착되는 하우징(2)내에는 세탁시 구동축(3)하부에 연결된 모터(도시는 생략함)의 회전력을 받아 세탁시 모터의 회전력을 세탁축(4)에 전달하는 한편, 탈수시 모터의 회전력을 받아 상,하부 탈수축(5a)(5b)과 함께 회전하는 동력전달부(6)가 내장되고, 상기 동력전달부(6)하부에 연결되는 구동축(3)의 구동축보스(7)와 구동축 외주면에 설치되는 하부 탈수축(5b)의 외주면에는 세탁시 구동축에만 모터의 회전력을 전달되도록 하며 탈수시에는 구동축(3) 및 하부 탈수축(5b)양측에 동시에 모터의 회전력이 전달되도록 하여 모터의 동력전달 경로를 단속하는 클러치 수단이 장착된다.Figure 2 is a longitudinal cross-sectional view showing the present invention and Figure 3 is a perspective view showing the clutch spring of Figure 2, Figure 4 is a principle diagram showing the operating state of the brake lever and the brake band, the housing mounted to the lower portion of the outer tank (1) (2) receives the rotational force of the motor (not shown) connected to the lower portion of the drive shaft (3) during washing, and transmits the rotational force of the motor during washing to the washing shaft (4), while receiving the rotational force of the motor during dehydration. A power transmission unit 6 that rotates together with the lower dehydration shafts 5a and 5b is built in, and is installed on the drive shaft boss 7 and the drive shaft outer circumferential surface of the drive shaft 3 connected to the lower portion of the power transmission unit 6. On the outer circumferential surface of the lower dehydration shaft 5b, the rotational force of the motor is transmitted only to the driving shaft when washing, and when the dehydration is performed, the rotational force of the motor is simultaneously transmitted to both sides of the driving shaft 3 and the lower dehydration shaft 5b. Equipped with clamping means The.

한편, 상기 동력전달부(6)는 구동축(3)상단 및 제1크랭크 축(8a)에 결합된 한쌍의 베벨기어(9a)(9b), 탈수축(5c)내의 양측에 베어링(10)으로 지지되어 회전운동을 하는 제1,2크랭크 축(8a)(8b)과, 상기 제1,2크랭크 축(8a)(8b)에 연결되어 회전운동을 왕복직선운동으로 변환하도록 하는 스카치 요오크 크랭크(Scotch Yoke Crank)(11)로 구성된다.On the other hand, the power transmission portion 6 is a pair of bevel gears (9a) (9b), coupled to the upper end of the drive shaft (3) and the first crank shaft (8a), as bearings (10) on both sides in the dehydration shaft (5c). Scotch yoke cranks connected to the first and second crankshafts 8a and 8b, which are supported and in rotational motion, and the first and second crankshafts 8a and 8b to convert the rotational motion into a reciprocating linear motion. (Scotch Yoke Crank) (11).

또한, 상기 클러치 수단은 구동축(3)하단을 감싸는 구동축보스(7) 및 하부 탈수축(5b)의 외주면에 설치되어 세탁시에는 모터의 회전구동력을 하부 탈수축(5b)에 전달하지 않고 탈수시에만 전달하는 클러치스프링(12)과, 상기클러치스프링(12)의 하단이 고정되고 외주면에 래칫(13)이 형성되는 클러치보스(14)와, 상기 클러치보스(14)의 래칫(13)에 선단이 걸릴 수 있도록 진입 또는 후퇴하는 걸림대(15)가 연결되며 외조의 측부에 설치된 배수밸브작동 겸용 솔레노이드(도시는 생략함)와 연동하는 브레이크레버(16)와, 브레이크레버(16)에 연결되어 하우징(2)내에 장착된 브레이크드럼(17)을 압착하여 클램핑 할 수 있도록 브레이크드럼 외주면을 따라 이격 설치되는 브레이크 밴드(18)로 구성된다.In addition, the clutch means is installed on the outer circumferential surface of the drive shaft boss 7 and the lower dewatering shaft 5b surrounding the lower end of the driving shaft 3, and when washing, the driving force of the motor is dehydrated without transmitting the rotational driving force of the motor to the lower dehydrating shaft 5b. Clutch spring 12 to be transmitted only, the clutch boss 14 is fixed to the lower end of the clutch spring 12 and the ratchet 13 is formed on the outer peripheral surface, and the end of the ratchet 13 of the clutch boss 14 A latch 15 for entering or retracting is connected to the brake lever 16 connected to the drainage valve acting solenoid (not shown) and the brake lever 16 connected to the housing so as to be caught. It consists of a brake band 18 spaced apart along the outer circumferential surface of the brake drum so as to compress and clamp the brake drum 17 mounted in (2).

이와같이 구성된 본발명은 제2도 내지 제4도에 나타낸 바와같이, 세탁모드시에는 구동축(3)만 회전하여 세탁축(4)이 직선왕복운동 하므로써 진동자(19)가 세탁물 및 세탁수에 공진현상을 일으켜 세탁을 수행하게 되며, 탈수모드시에는 구동축(3) 및 하부탈수축(5b)이 클러치스프링(12)에 함께 클램핑되어 고속회전 하므로써 탈수가 이루어진다.In the present invention configured as described above, as shown in FIGS. 2 to 4, in the washing mode, the drive shaft 3 rotates so that the washing shaft 4 linearly reciprocates so that the vibrator 19 resonates with the laundry and the washing water. Washing is performed, and in the dehydration mode, the drive shaft 3 and the lower dehydration shaft 5b are clamped together in the clutch spring 12 to dehydrate by rotating at a high speed.

이때의 작동을 보다 세분하여 상세히 살펴보면 다음과 같다.In more detail, the operation at this time is as follows.

먼저, 세탁시에 사용자가 세탁모드를 선택하면 세탁수가 외조(1)에서 빠져나가지 못하도록 배수밸브(21)가 닫히게 되는데 이때, 브레이크레버(16)는 제4도의 (가)에 나타낸 바와같이 비틀림스프링(22)의 복원력에 의해 힌지핀(23)을 중심으로 반시계 방향으로 회전하게 됨에 따라 일단이 고정단(24)에 고정된 브레이크밴드(18)는 타단에 연결된 브레이크레버(16)의 회전력을 받아 브레이크드럼(17)을 압착하여 클램핑 하게된다.First, when the user selects the washing mode during washing, the drain valve 21 is closed to prevent the washing water from escaping from the outer tank 1. At this time, the brake lever 16 has a torsion spring as shown in (a) of FIG. As the rotating force of the hinge pin 23 rotates about the hinge pin 23 in the counterclockwise direction, the brake band 18 having one end fixed to the fixed end 24 receives the rotational force of the brake lever 16 connected to the other end. The brake drum 17 is crimped by pressing.

또한, 상기한 브레이크레버(16)가 제4도의 (가)에 나타낸 바와같이 반시계방향으로 비틀림스프링(22)의 복원력을 받아 회전할때 브레이크레버(16)에 연결된 걸림대(15)는 브레이크레버(16)와 함께 연동하여 제2도의 (가)에 나타낸 바와같이 클러치보스(14)외주면에 형성된 래칫(ratchet)(13)과 래칫(13)사이에 진입함과 동시에 래칫(13)에 걸려 브레이크레버(16)와 같이 구동축(3)의 반대방향으로 회전하여 클러치보스(14)를 일정각도 회전시키게 된다.In addition, when the brake lever 16 rotates under the restoring force of the torsion spring 22 in the counterclockwise direction as shown in FIG. 4A, the latch 15 connected to the brake lever 16 is brake lever. In conjunction with (16), as shown in (a) of FIG. 2, the ratchet 13 and the ratchet 13 formed on the outer circumferential surface of the clutch boss 14 enter the ratchet 13 and are caught by the ratchet 13 at the same time. Like the lever 16, the clutch boss 14 is rotated at an angle by rotating in the opposite direction of the drive shaft 3.

이에따라, 클러치보스(14)에 하단이 고정되고 하부탈수축(5b)에 상단이 고정된 클러치스프링(12)은 클러치보스(14)의 회전에 의한 회전력을 받게되는데, 상단이 하부 탈수축(5b)에 고정되어 있으므로 인해 클러치스프링(12)은 회전하지 못하므로 비틀림모멘트를 받는 효과가 발생하여 클러치스프링(12)의 내경이 커지게 된다. 따라서, 클러치스프링(12)의 내주면은 구동축(3)에 결합된 구동축보스(7)외주면으로 부터 일정간격 이격되어 상호간섭이 배제되므로 모터의 구동력을 받아 구동축(3)이 회전할때 하부 탈수축(5b)은 회전하지 않고 정지상태를 유지한다.Accordingly, the clutch spring 12 having the lower end fixed to the clutch boss 14 and the upper end fixed to the lower dehydration shaft 5b receives a rotational force by the rotation of the clutch boss 14, and the upper end thereof has a lower dewatering shaft 5b. Since the clutch spring 12 is not rotated because it is fixed, the effect of receiving the torsion moment occurs, the inner diameter of the clutch spring 12 is increased. Therefore, since the inner circumferential surface of the clutch spring 12 is spaced apart from the outer circumferential surface of the drive shaft boss 7 coupled to the drive shaft 3 and mutual interference is excluded, the lower dehydration shaft is reduced when the drive shaft 3 rotates under the driving force of the motor. 5b does not rotate and remains stationary.

한편, 구동축보스(7)와 하부 탈수축(5b)의 접촉면 및 구동축(3)과 하부 탈수축(5b)의 접촉면 사이에는 미끄럼 마찰에 의한 작은 저항이 존재하게 되는데, 만약 이로 인해 하부 탈수축(5b)에 회전력이 전달되어 회전하려고 할 경우에는 하부 탈수축(5b)에 결합된 브레이크드드럼(17)의 회전방향이 시계방향이므로 제4도의 (가)에 나타낸 바와같이 브레이크드럼(17)의 회전력은 브레이크밴드(18)를 조이는 힘으로 작용하여 자기체결(Self Clamping)상태가 된다.On the other hand, there is a small resistance due to sliding friction between the contact surface of the drive shaft boss 7 and the lower dehydration shaft 5b and the contact surface of the drive shaft 3 and the lower dehydration shaft 5b. When the rotational force is transmitted to 5b) to rotate, the rotation direction of the brake drum 17 coupled to the lower dehydration shaft 5b is clockwise, so as shown in FIG. The rotational force acts as a force for tightening the brake band 18 to a self clamping state.

따라서, 세탁시에는 구동축(3)과 구동축보스(7) 및 클러치보스(14)만이 회전하여 모터의 구동력이 베벨기어(9a)(9b)를 통해 제1,2크랭크 축(4) 및 진동자(19)의 왕복직선 운동으로 변환되므로써 세탁이 수행되어 진다.Therefore, during washing, only the drive shaft 3, the drive shaft boss 7, and the clutch boss 14 rotate so that the driving force of the motor is transmitted through the bevel gears 9a and 9b to the first and second crank shafts 4 and the vibrator ( The washing is performed by converting the linear reciprocation in 19).

한편, 탈수시에는 세탁수의 배수를위해 배수밸브(21)가 개방되며, 이때 솔레노이드(25)의 작용에 의해 브레이크레버(16)는 연동하여 구동축(3)의 회전방향과 동일한 방향으로 일정각도 만큼 회전하게 된다.On the other hand, during dehydration, the drain valve 21 is opened for draining the wash water, and the brake lever 16 is interlocked by the action of the solenoid 25 so that the brake lever 16 is interlocked with a predetermined angle in the same direction as the rotational direction of the drive shaft 3. Rotate by.

이때, 브레이크레버(16)에 연결된 걸림대(15)는 브레이크레버(16)와 함께 회전하여 클러치보스(14)의 외주면에 형성된 래칫(13)홈에서 빠져나와 제2도의 (나)에 나타낸 바와같이 길림대(15)선단과 래칫(13)과의 간섭이 배제된 상태가 된다.At this time, the latch 15 connected to the brake lever 16 rotates together with the brake lever 16 to escape from the ratchet 13 groove formed on the outer circumferential surface of the clutch boss 14, as shown in FIG. 2B. The interference between the tip of the jiln stand 15 and the ratchet 13 is eliminated.

이와동시에 클러치보스(14)의 내주면에 삽입되며 하단이 고정된 클러치스프링(12)은 클러치보스(14)가 원위치하여 하단에 가해졌던 힘이 제거됨에 따라 복원력에 의해 구동축보스(7) 및 하부탈수축(5b)외주면을 클램핑하게 된다.At the same time, the clutch spring 12 inserted into the inner circumferential surface of the clutch boss 14 and having the lower end fixed thereto is driven by the restoring force as the clutch boss 14 is removed and the force applied to the lower end is removed. The outer peripheral surface of the shrinkage 5b is clamped.

또한, 탈수시에는 브레이크레버(16)가 구동축(3)의 회전방향으로 일정각도 만큼 회전함에 따라 브레이크드럼(17)을 압착하고 있던 브레이크밴드(18)가 제4도의 (나)에 나타낸 바와같이 브레이크드럼(17)의 외주면에서 이격되어 브레이크드럼(17)의 회전을 방해하지 않게된다.In dewatering, as the brake lever 16 rotates by a predetermined angle in the rotational direction of the drive shaft 3, the brake band 18, which has been pressing the brake drum 17, as shown in FIG. 4B. It is spaced apart from the outer circumferential surface of the brake drum 17 so as not to interfere with the rotation of the brake drum 17.

따라서, 탈수시 모터의 구동력은 구동축(3)에 결합된 구동축보스(7) 및 하부 탈수축(5b)을 클러치스프링(12)이 함께 클램핑하고 있으므로 인해 구동축(3) 및 하부탈수축(5b)에 동시에 전달되는데, 구동축(3)상단의 구동베벨기어(9a)에 맞물리는 종동베벨기어(9b)는 구동베벨기어(9a)의 회전각속도와 동일한 각속도로 구동축(3)주위를 운동하므로 인해 세탁축(4) 및 진동자(19)는 왕복운동을 하지 못한채 공회전하게 된다.Therefore, the driving force of the motor during dehydration is because the clutch spring 12 clamps the driving shaft boss 7 and the lower dehydration shaft 5b coupled to the driving shaft 3 together, so that the driving shaft 3 and the lower dehydration shaft 5b are depressed. At the same time, the driven bevel gear 9b meshing with the drive bevel gear 9a on the top of the drive shaft 3 moves around the drive shaft 3 at the same angular speed as the rotational angular speed of the drive bevel gear 9a. The shaft 4 and the vibrator 19 are idle without reciprocating motion.

한편, 상기 클러치스프링(12)에 클램핑되어 구동축(3)과 함께 회전하는 하부탈수축(5b)의 회전력은 브레이크드럼(17)을 통해 상부탈수축(5a)으로 전달되어 내조(20)를 회전시키므로써 탈수가 이루어지게 된다.Meanwhile, the rotational force of the lower dehydration shaft 5b clamped to the clutch spring 12 and rotating together with the drive shaft 3 is transmitted to the upper dehydration shaft 5a through the brake drum 17 to rotate the inner tub 20. Dehydration is achieved.

따라서, 본발명은 종래와 같이 탈수를 위한 별도의 모터를 설치할 필요가 없을뿐만 아니라, 모터를 일방향으로만 회전시키면 되므로 구동부의 전기적회로 구성이 보다 간결해지며 이로인해 모터의 구동효율 또한 향상된다.Therefore, the present invention does not need to install a separate motor for dehydration as in the related art, and since the motor only needs to be rotated in one direction, the electric circuit configuration of the driving unit is more concise, thereby improving driving efficiency of the motor.

또한, 모터를 한 방향으로만 회전시키면 되므로 내조의 역회전을 방지하는 역전 방지클러치 등의 복잡한 장치를 부가할 필요가 없으므로 제품의 콤팩트화 및 제조단가의 절감을 기할 수 있는 효과가 있다.In addition, since the motor only needs to be rotated in one direction, it is not necessary to add a complicated device such as a reverse prevention clutch that prevents reverse rotation of the inner tank, thereby making it possible to compact the product and reduce manufacturing costs.

이상에서와 같이, 본발명은 저주파 진동세탁기가 모터의 일방향 회전만으로도 효율적인 세탁 및 탈수기능을 수행할 수 있도록 한 매우 유용한 발명이다.As described above, the present invention is a very useful invention that allows the low-frequency vibration washing machine to perform efficient washing and dehydration function only by one-way rotation of the motor.
