본 고안은 저주파 진동세탁기의 진동보호장치에 관한 것으로, 특히 세탁시 과도하게 상하로 진동하는 것을 검출하여 세탁기를 보호하기 위한 진동보호장치에 관한 것이다.The present invention relates to a vibration protection device for a low frequency vibration washing machine, and more particularly, to a vibration protection device for protecting a washing machine by detecting excessive vibration up and down during washing.

제1도는 종래의 회전식 세탁기의 진동보호장치의 구조도이다.1 is a structural diagram of a vibration protection device of a conventional rotary washing machine.

종래의 회전식 세탁기의 진동보호장치는 제1도에 도시한 바와 같이 회전운동을 하는 세탁조(2)의 하단에 댐퍼(4, 5)로 케이스(1)의 상단을 접속시켜 구성되어 세탁조(2)의 회전운동시 과도하게 발생되는 진동으로부터 세탁기를 보호한다.Vibration protection device of the conventional rotary washing machine is configured by connecting the upper end of the case (1) with dampers (4, 5) to the lower end of the washing tank (2) to rotate as shown in FIG. It protects the washing machine from excessive vibration generated during the rotation movement.

즉, 세탁물(3)이 한쪽 방향으로 몰려서 있는 경우 세탁조(2)의 회전운동시 과도한 진동이 발생하는데 댐퍼(4, 5)를 이용하여 과도한 진동발생시 이를 흡수하여 세탁기를 보호한다.That is, when the laundry 3 is flocked in one direction, excessive vibration occurs during the rotational movement of the washing tank 2, and the damper 4, 5 is used to absorb the excessive vibration to protect the washing machine.

제2도는 일반적인 저주파 진동 세탁기의 진동보호장치의 구조도이다.2 is a structural diagram of a vibration protection device of a general low frequency vibration washing machine.

일반적인 저주파 진동 세탁기의 진동보호장치는 제2도에 도시한 바와 같이 모터(16)의 동작에 의해 상하운동을 하는 디스크(Disk)(17), 디스크(Disk)(17)의 상하운동에 따라 세탁물(13)의 세탁을 수행하는 세탁조(12), 세탁조(12)의 바닥면 하단과 케이스(11)의 바닥면 상단에 접속된 댐퍼(14,15)로 구성된다.Vibration protection device of a general low frequency vibration washing machine according to the vertical motion of the disk (Disk) 17, the disk (Disk) 17 to move up and down by the operation of the motor 16 as shown in FIG. And a damper 14 and 15 connected to the lower end of the bottom surface of the washing tank 12 and the upper end of the bottom surface of the case 11.

모터(16)가 동작하여 디스크(17)가 상하운동을 하는 경우 상하로 진동이 발생한다.When the motor 16 operates and the disk 17 moves up and down, vibration is generated up and down.

특히, 세탁물(13)이 한쪽방향으로 몰려있는 경우 모터(16)를 작동시키면 과도한 진동이 발생하는데, 이때 댐퍼(14, 15)가 발생된 진동을 흡수하여 세탁기를 보호하게 된다.In particular, when the laundry 13 is driven in one direction, excessive vibration occurs when the motor 16 is operated. At this time, the dampers 14 and 15 absorb the generated vibration to protect the washing machine.

그러나, 일반적인 저주파 진동세탁기의 진동보호장치는 지나친 진동이 발생하여도 세탁기가 작동하는 한 계속해서 모터가 구동되므로, 세탁물(13)이 골고루 펴질때까지 과도한 진동이 발생하여 세탁기의 수명이 단축되는 문제점이 있었다.However, the vibration protection device of the general low frequency vibration washing machine has a problem that the vibration of the washing machine is operated as long as the washing machine is operated even if excessive vibration occurs. There was this.

상기 문제점을 개선하기 위해 본 고안은 저주파 진동세탁기에 있어서, 세탁시 과도하게 상하로 진동하는 것을 검출하여 세탁기를 보호하기 위한 진동보호장치를 제공함에 그 목적이 있다.In order to improve the above problems, the present invention has a purpose to provide a vibration protection device for protecting a washing machine by detecting excessive vibration up and down during washing in a low frequency vibration washing machine.

상기 목적을 달성하기 위해 본 고안은 세탁조의 상하진동을 검출하는 진동검출수단, 및 상기 진동검출수단으로부터 출력되는 신호에 따라 모터를 구동시키는 모터 구동수단으로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the vibration detection means for detecting the vertical vibration of the washing tank, and a motor drive means for driving the motor in accordance with the signal output from the vibration detection means.

이하, 첨부된 도면을 참조하여 본 고안의 일실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

제3도는 본 고안에 의한 저주파 진동 세탁기의 진동보호장치의 구성도이다.3 is a block diagram of a vibration protection device of a low frequency vibration washing machine according to the present invention.

본 고안에 의한 저주파 진동세탁기의 진동보호장치는 제3도에 도시한 바와 같이 진동검출부(20)와 모터구동부(21)로 구성된다.Vibration protection device of the low frequency vibration washing machine according to the present invention is composed of a vibration detection unit 20 and the motor driving unit 21 as shown in FIG.

진동검출부(20)는 세탁조의 상하진동을 검출하여 상하진동의 정도가 기준치 이상이 되면 모터구동부(21)로 모터정지신호를 출력한다.The vibration detecting unit 20 detects the up and down vibration of the washing tank and outputs a motor stop signal to the motor driving unit 21 when the degree of up and down vibration is equal to or more than the reference value.

모터구동부(21)는 진동검출부(20)로부터 출력되는 모터정지신호를 이용하여 모터(22)의 구동을 제어한다.The motor driver 21 controls the driving of the motor 22 by using the motor stop signal output from the vibration detector 20.

세탁조가 상하운동을 하면 진동검출부(20)에서 기준치 이상의 진동이 발생하는 것을 감지하여 모터구동부(21)로 모터정지신호를 출력한다.When the washing tank moves up and down, the vibration detection unit 20 detects that the vibration above the reference value is generated and outputs a motor stop signal to the motor driving unit 21.

모터정지신호는 터구동부(21)를 제어하여 모터(22)가 더 이상 상하운동을 하지 못하도록 정지시킴으로써 세탁기를 보호한다.The motor stop signal controls the driving unit 21 to protect the washing machine by stopping the motor 22 from moving up and down.

제4도는 제3도의 진동검출부(20)의 세부 구성도이다.4 is a detailed configuration diagram of the vibration detection unit 20 of FIG.

진동검출부(20)는 제4도에 도시한 바와 같이 전원(Vcc)에 일단이 연결되어 세탁조(12)의 상하 진동의 크기가 기준치 이상이면 동작하는 스위치(SW1), 스위치(SW1)의 타단에 베이스가 연결되고 전원(Vcc)에 콜렉터가 연결되고 에미터가 접지되어 스위치(SW1)의 동작에 따라 온/오프(ON/OFF)되는 트랜지스터(Q1), 및 트랜지스터(Q1)의 콜렉터와 모터제어신호 입력단자에 입력단이 연결된 AND 게이트(G1)로 구성된다.Vibration detecting unit 20 is a switch (SW 1), the switch (SW 1) which is one end is connected to a power source (Vcc) if the size of the vertical vibration of the washing tub 12, a reference value or more operations as shown in FIG. 4 Transistor Q 1 , which is connected to a base at the other end, a collector is connected to a power supply Vcc, and an emitter is grounded, and is turned on / off according to the operation of the switch SW 1 , and a transistor Q 1 . It consists of an AND gate (G 1 ) connected to the collector and the motor control signal input terminal.

세탁조(12)가 기준치이내에서 상하 진동운동을 하면 스위치(SW1)가 오프(OFF)되고 트랜지스터(Q1)가 오프되므로, 트랜지스터(Q1)의 콜렉터에 연결된 AND 게이트(G1)에 하이레벨(High Level)신호가 입력된다.When the washing tank 12 vibrates up and down within a reference value, the switch SW 1 is turned off and the transistor Q 1 is turned off. Therefore, the washing tank 12 has a high level at the AND gate G1 connected to the collector of the transistor Q 1 . (High Level) signal is input.

그러므로, AND 게이트(G1)의 다른 입력단으로 외부로부터 입력되어 모터의 구동을 제어하는 모터제어신호에 따라 모터구동부(21)가 동작하여 모터(22)를 구동시키게 된다.Therefore, the motor driving unit 21 operates in accordance with a motor control signal input from the outside to the other input terminal of the AND gate G1 to control the driving of the motor, thereby driving the motor 22.

또한, 세탁조(12)가 기준치 이상, 즉 세탁기의 수명을 단축시키는 정도의 상하 진동운동을 하면 스위치(SW1)를 구동시키게 되고, 스위치(SW1)가 온(ON)되면 트렌지스터(Q1)가 온되어 트렌지스터(Q1)의 콜렉터에 연결된 AND 게이트(G1)로 로우레벨(Low Level) 신호가 입력되어, 외부로부터 입력되는 모터제어신호에 관계없이 모터구동부(21)로 우레벨(Low Level) 신호가 출력되므로 모터(22)의 구동이 정지된다.In addition, when the washing tank 12 performs the up and down oscillation movement of the reference value, that is, shortening the life of the washing machine, the switch SW 1 is driven. When the switch SW 1 is turned on, the transistor Q 1 A low level signal is input to the AND gate G1 connected to the collector of the transistor Q 1 to turn the low level signal to the motor driver 21 regardless of the motor control signal input from the outside. ), The motor 22 stops driving.

상기와 같이 구성되어 동작하는 본 고안은 세탁기의 과도한 진동을 방지하므로 과도한 진동으로 발생되는 세탁기의 수명단축을 방지하는 효과가 있다.The present invention configured and operated as described above prevents excessive vibration of the washing machine, thereby preventing the shortening of the life of the washing machine generated by excessive vibration.
