After operating the microwave coil drive device for a certain time, it automatically stops and operates the microwave drive device for a certain time by using the heating function and the microwave timer. Simultaneous use of the mat's heater and microwave coil prevents the risk of fire due to overheating and damage to the components of the mat.

그러나, 상기와 같은 초장파 전기매트용 온도조절기의 과열방지용 장치는 초장파 타이머 또는 초장파 코일 구동장치의 구성소자가 고장 났을 경우 전원이 계속해서 초장파 코일로 공급되어 초장파 코일이 과열되는 것을 방지할 수 있는 기능이 없다.However, the device for preventing overheating of the thermostat for the ultra-high frequency electric mat as described above has a function that can prevent the ultra-high frequency coil from overheating when the power is continuously supplied to the ultra-high frequency coil when a component of the ultra-high-frequency timer or the ultra-high frequency coil driving device fails. There is no

따라서, 본 발명의 목적은 초장파 발생기와 이의 작동을 제어하는 구동장치 사이에 배치되어, 구동장치의 고장시 발생되는 초장파 발생기의 과열을 간접적으로 검출하여 전원공급을 자동 차단함으로써, 안전사고를 미연에 방지할 수 있는 초장파발생기의 과열방지장치를 제공하는 것이다.Therefore, an object of the present invention is disposed between the ultra-high frequency generator and the driving device for controlling the operation thereof, by indirectly detecting the overheating of the ultra-high frequency generator generated in the event of a failure of the driving device to automatically cut off the power supply, thereby preventing safety accidents. It is to provide an overheating prevention device of a microwave generator which can be prevented.

상기와 같은 목적을 달성하기 위한 본 발명의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.

도 1을 참조하면, 본 발명에 따른 초음파 발생기의 과열방지장치(10)는 초음파 발생기(3)의 발열온도와 비례하는 발열온도값을 갖는 저항(R1)과, 상기 저항(R1)과 근접 또는 접촉되도록 설치되어 상기 저항(R1)의 발열온도에 의해 온/오프되는 바이메탈(B1)로 구성되며, 상기 저항(R1)의 일단이 구동장치(5)의 전원출력단에 연결되고, 상기 저항(R1)의 타단이 바이메탈(B1)의 가동자(11)에 연결되고, 바이메탈(B1)의 어느 한 고정단(13)이 초음파 발생기(3)에 접속된다.Referring to FIG. 1, an overheat prevention apparatus 10 of an ultrasonic generator according to the present invention may include a resistor R1 having an exothermic temperature value proportional to an exothermic temperature of an ultrasonic generator 3, and adjacent or adjacent to the resistor R1. It is configured to be in contact with the bimetal (B1) is turned on / off by the heating temperature of the resistor (R1), one end of the resistor (R1) is connected to the power output terminal of the drive device 5, the resistor (R1) The other end of) is connected to the mover 11 of the bimetal B1, and one fixed end 13 of the bimetal B1 is connected to the ultrasonic generator 3.

상기 저항(R1)은 초장파 발생기(3)의 발열온도에 비례하는 발열온도값을 갖도록 설정되고, 상기 저항(R1)의 발열온도에 따라 상기 바이메탈(B1)의 온/오프 설정값을 설정할 수 있다. 예를 들어, 초장파 발생기(3)의 발열온도가 70℃일 때, 저항(R1)의 발열온도가 70℃( 또는 70℃에 비례하는 발열온도, 예컨대 50℃)에 도달되는 저항을 선택할 수 있으며, 이때, 바이메탈(B1)의 턴오프 설정값을 갖는 바이메탈을 선택할 수 있다.The resistor R1 may be set to have an exothermic temperature value proportional to the exothermic temperature of the microwave generator 3, and may set an on / off setting value of the bimetal B1 according to the exothermic temperature of the resistor R1. . For example, when the exothermic temperature of the ultra-high wave generator 3 is 70 ° C, the resistance at which the exothermic temperature of the resistor R1 reaches 70 ° C (or an exothermic temperature proportional to 70 ° C, for example 50 ° C) may be selected. In this case, the bimetal having the turn-off setting value of the bimetal B1 may be selected.

상기 구동장치(5)는 대한민국 실용신안등록 제405789호의 "초장파 전기매트용 온도조절기의 과열방지용 장치"에 소개된 16비트 타이머, 제로크로스 옵토아이솔레이터 및 트라이악으로 구성된 초장파 코일 구동장치를 적용하거나, 이미 잘 알려진 다른 종류의 타이머를 적용할 수 있다. The driving device 5 is applied to the ultra-high-frequency coil driving device composed of a 16-bit timer, zero-cross opto-isolator and triac introduced in "apparatus for preventing overheating of ultra-high temperature electric mat thermostat" of Korean Utility Model Registration No. 405789, Other types of timers that are well known can be applied.

상기와 같이 구성된 본 발명에 따른 초장파 발생기의 과열방지장치는 다음과 같이 작용한다.The overheat prevention device of the ultra-high wave generator according to the present invention configured as described above acts as follows.

먼저, 정상 동작시, 저항(R1)의 발열온도가 설정값(70℃ 또는 이에 비례하는 온도) 이하의 상태이며, 이때, 바이메탈(B1)의 가동단자(11)가 초장파 발생기(3)에 연결된 고정단(13)에 접속되어 턴온 상태를 유지함으로써, 구동장치(5)의 출력단에서 인가된 전원이 본 발명에 따른 과열방지장치(10)를 통해 초장파 발생기(3)로 공급되어, 초장파 발생기(3)가 작동된다.First, in the normal operation, the heat generation temperature of the resistor R1 is below a set value (70 ° C. or a temperature proportional thereto), and at this time, the movable terminal 11 of the bimetal B1 is connected to the ultra-wave generator 3. By being connected to the fixed end 13 and maintaining the turn-on state, the power applied from the output end of the driving device 5 is supplied to the ultra-high wave generator 3 through the overheat prevention device 10 according to the present invention, and the ultra-high wave generator ( 3) is activated.

이와 같은 상태에서, 구동장치(5)의 주요 소자에 고장이 발생하여, 전원이 계속해서 초장파 발생기로 유입되는 경우, 저항(R1) 부품의 자체 온도가 초장파 발생기(300)의 발열온도에 비례하여 크게 상승하게 된다.In this state, when a main element of the driving device 5 fails and power is continuously introduced into the microwave generator, the self temperature of the resistor R1 component is proportional to the heating temperature of the microwave generator 300. It will rise greatly.

이때 상기 저항(R1)의 온도를 바이메탈(B1)이 감지하게 되며, 저항의 발열온도가 설정값에 도달되면, 감지온도에 의해 바이메탈(B1)의 가동자(11)가 오프단자(15)로 이동되어, 바이메탈(B1)이 턴 오프됨으로써, 상기 초장파 발생기(3)로 공급되는 전류를 차단하게 된다. 이것에 의해, 구동장치(5)의 고장으로 인해 발생할 수 있는 초장파 발생기(3)의 과열로 인한 화재 등의 위험요소를 방지하게 된다.At this time, the bimetal B1 senses the temperature of the resistor R1. When the heating temperature of the resistor reaches a set value, the movable element 11 of the bimetal B1 is turned off by the sensing temperature. The bimetal B1 is turned off to block the current supplied to the ultra-wave generator 3. This prevents a risk factor such as a fire due to overheating of the ultra long wave generator 3 which may occur due to a failure of the driving device 5.

위에서 설명한 바와같이, 본 발명에 따른 초음파 발생기의 과열방지장치는 초장파 발생기와 이의 작동을 제어하는 구동장치 사이에 배치되어, 구동장치의 고장시 발생되는 초장파 발생기의 과열을 간접적으로 검출하여 전원공급을 자동 차단함으로써, 안전사고를 미연에 방지할 수 있는 효과가 있다.As described above, the overheat prevention device of the ultrasonic generator according to the present invention is disposed between the ultra-high frequency generator and the driving device for controlling the operation thereof, and indirectly detects the overheating of the ultra-high frequency generator generated in the event of a failure of the driving device to supply power. By automatically blocking, there is an effect that can prevent accidents in advance.
