본 고안은 세탁기 건조히터의 보호회로에 관한 것으로, 더욱 상세하게는 세탁기 건조장치의 모터와 히터를 하나의 회로를 이용하여 동시에 보호할 수 있도록 한 세탁기 건조히터의 보호회로에 관한 것이다.The present invention relates to a protection circuit of a washing machine drying heater, and more particularly, to a protection circuit of a washing machine drying heater to protect the motor and the heater of the washing machine drying apparatus using a single circuit at the same time.
최근, 세탁기는 세탁에서 헹굼, 탈수는 물론 건조시킬 수 있도록 개발되었다. 이러한 건조장치는 장마철이나 우기에는 햇볕이 잘 들지 않고, 특히 공기 중에 수분이 많아 원활하게 건조시킬 수 없는 불편한 문제점들을 해결할 수 있는 장치이다. 본 발명은 이러한 세탁기의 건조장치에 사용되는 세탁기 건조히터의 보호회로에 관한 것이다.Recently, a washing machine has been developed to allow rinsing, dehydration, as well as drying in washing. Such a drying device is a device that can solve the uncomfortable problem of not drying in the rainy season or rainy season, in particular, there is a lot of moisture in the air smoothly. The present invention relates to a protection circuit of a washing machine drying heater used in the drying apparatus of such a washing machine.
종래의 세탁기 건조히터의 보호회로는 제 1 도에 도시된 바와 같이 전류원(11)의 양극단자에 온도휴즈(12)가 연결되고, 노드(N1)를 분기점으로 하여 히터회로와 모터회로로 분기되어 있다.Protection circuit of a conventional washing machine drying heater and a temperature fuse 12 is connected to the positive terminal of the current source 11 as shown in FIG. 1, to the node (N 1) in the fork branches to the heater circuit and the motor circuit It is.
히터회로는 스위치(13)와 히터(16)가 직렬로 연결되어 있다.In the heater circuit, the switch 13 and the heater 16 are connected in series.
또한, 모터(15)는 전단에 모터보호회로인 온도휴즈(14)와 직렬로 접속되고 그 후단에 온도휴즈(17)가 게이트단자(G)의 제어신호에 의해 양방향으로 전류를 통전시킬 수 있는 트라이액(18)을 통하여 전류원(11)의 음극단자와 연결되어 있다.In addition, the motor 15 is connected in series with the temperature fuse 14, which is a motor protection circuit at the front end, and the temperature fuse 17 at the rear end thereof can conduct current in both directions by the control signal of the gate terminal G. The triac 18 is connected to the negative terminal of the current source 11.
이와 같이 구성된 종래의 세탁기 건조히터의 보호회로는 히터(16)와 모터(15)가 각각 별개로 온도휴즈(12)와 모터보호용 온도휴즈(14)를 설치하고 있어 이상발생시 보호작동이 개별적으로 행해지게 되어 있다. 따라서 자연히 보호작동시간이 지연되는 문제점이 있었다.In the protection circuit of the conventional washing machine drying heater configured as described above, the heater 16 and the motor 15 are separately provided with the temperature fuse 12 and the motor protection temperature fuse 14, so that when an abnormality occurs, the protection operation is performed separately. It is supposed to be. Therefore, there was a problem that the protective operation time is delayed naturally.
따라서, 본 고안은 전술한 문제점을 해결하기 위해 안출된 것으로서, 그 목적은 모터와 히터중 어느 하나만 과열해도 보호회로가 작동하는 세탁기 건조히터의 보호회로를 제공함에 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, the object is to provide a protection circuit of a washing machine drying heater operating a protection circuit even if only one of the motor and the heater overheating.
전술한 목적을 달성하기 위한 본 고안에 따른 세탁기 건조히터의 보호회로의 특징은 적어도 전원모터 및 히터를 구비하는 세탁기 건조히터의 보호회로에 있어서, 상기 모터와 히터가 병렬 연결되고, 그 전단에 모터가 동작하지 않을 경우 즉시 감지되는 감지휴즈가 설치되어, 히터와 모터의 회로를 차단할 수 있도록 구성된 것에 있다.A characteristic of the protection circuit of a washing machine drying heater according to the present invention for achieving the above object is in the protection circuit of a washing machine drying heater having at least a power motor and a heater, the motor and the heater is connected in parallel, the motor in front of the Is installed so that the detection fuse is immediately detected when it does not operate, it is configured to cut off the circuit of the heater and the motor.
이하, 첨부도면에 의거 본 고안에 따른 세탁기 건조히터의 보호회로의 바람직한 하나의 실시 예를 상세히 설명한다.Hereinafter, a preferred embodiment of the protection circuit of the washing machine drying heater according to the present invention based on the accompanying drawings will be described in detail.
제 2 도에 도시된 바와 같이, 전류원(21)은 모터보호용 휴즈(22)와 전기적으로 연결되어 있고, 노드(N1)는 모터(25)와 히터(26)를 공통점으로 하고 있다. 모터(25)는 게이트(G)단자의 제어신호에 의해 양방향 모두 통전할 수 있는 트라이액(28)과 연결되어 있고 또한 온도휴즈(27)와 직렬로 연결되어 있다.As shown in Fig. 2, the current source 21 is electrically connected to the motor protection fuse 22, and the node N 1 has the motor 25 and the heater 26 in common. The motor 25 is connected to a triac 28 capable of energizing both directions by a control signal of the gate G terminal, and also connected in series with a temperature fuse 27.
히터는 전술한 노드(N1)와 전기적으로 연결되고, 스위치(23)와 직렬로 연결되어 있다. 따라서, 모터(25)와 히터(26)는 노드(N1)를 통하여 분기된다.The heater is electrically connected to the node N 1 described above and is connected in series with the switch 23. Thus, the motor 25 and the heater 26 branch through the node N 1 .
이와 같이 구성된 본 고안은 전류원(21)으로부터 모터(25)와 히터(26)에 전류가 공급된다. 스위치(23)의 스위칭작용에 의해 히터(26)에 전류공급이 제어된다.The present invention configured as described above is supplied with electric current from the current source 21 to the motor 25 and the heater 26. The supply of current to the heater 26 is controlled by the switching action of the switch 23.
제 1 도와 같이 구성된 종래의 세탁기 건조히터의 보호회로는 모터와 히터가 각각개별 온도휴즈를 설치하고 있어서, 만약 모터(25)가 구동되지 않을 경우 히터(26)쪽으로만 전류가 흐르게 되고 따라서 히터가 과열되는데 그 과열온도의 감지는 매우 느리다. 그러나, 본 고안의 경우에는 모터(25)가 구동되지 않으면 모터의 온도가 올라가 모터(25)의 전단에 연결된 모터보호용 휴즈(22)가 동작해서 히터(26)및 모터(25)의 회로를 모두 차단하게 되어 히터 및 모터의 회로의 과열을 방지하게 된다.In the protection circuit of the conventional washing machine drying heater configured as shown in FIG. 1, the motor and the heater each have a separate temperature fuse, so that if the motor 25 is not driven, current flows only to the heater 26, so that the heater It is overheated and the detection of the overheating temperature is very slow. However, in the case of the present invention, if the motor 25 is not driven, the temperature of the motor rises and the motor protection fuse 22 connected to the front end of the motor 25 operates to operate both the circuits of the heater 26 and the motor 25. This prevents overheating of the circuits of the heater and the motor.
이상 설명한 바와 같이, 본 고안에 따른 세탁기 건조히터의 보호회로는 이상 사고발생시 즉시 작동할 수 있어 과열로 인한 회로보호에 매우 유익한 이점을 가진다.As described above, the protection circuit of the washing machine drying heater according to the present invention can immediately operate in the event of an accident has a very beneficial advantage in protecting the circuit due to overheating.
