It relates to a thermostat device.

건강에 대한 관심이 고조되면서 돌침대, 돌매트 및 황토를 이용한 매트들이 개발되어 사용되고 있는데, 이러한 종류의 매트는 원석이나 황토로 부터 나오는 원적외선을 이용하여 환자를 치료하거나 건강증진을 도모한다.With increasing interest in health, stone beds, stone mats and ocher mats have been developed and used. These types of mats use far-infrared rays from stones or ocher to treat patients or promote health.

There was a problem that it is difficult to accurately adjust the amount of heat generated in the heat generating member 120 in accordance with the temperature adjustment by using a bimetal switch to cut off the power supply.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 온열을 발생하는 히터 또는 면상발열체와 같은 발열부재의 발열량을 단계적으로 가변할 수 있으며, 아울러 히터의 발열량을 사용자가 원하는 온도로 정확하게 조정할 수 있는 엔코더를 이용한 건강 매트의 온도 조절 장치를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been invented to solve the above problems, it is possible to vary the amount of heat generated in the heating element such as a heater or a planar heating element that generates heat, and also to adjust the amount of heat of the heater to the desired temperature accurately It is an object of the present invention to provide a temperature control device for a health mat using an encoder.

도 1은 본 발명에 따른 건강 매트의 온도 조절 장치를 나타낸 회로도로, 마이컴(U1)에는 로터리식 온도조절용 엔코더(E1)가 접속되어 있으며, 또한 마이컴(U1)의 구동에 필요한 클럭신호를 발생하는 공진기(RES)와 미도시된 히터 또는 면상발열체로 이루어진 발열부재(H1)의 온도를 검출하는 제1 및 제2 온도검출센서 (S1,S2)가 상기 마이컴(U1)에 각각 접속되어 있다.1 is a circuit diagram showing a temperature regulating device of a health mat according to the present invention, in which a microcomputer U1 is connected with a rotary temperature controlling encoder E1, and generates a clock signal for driving the microcomputer U1. The first and second temperature detection sensors S1 and S2 for detecting the temperature of the resonator RES and the heat generating member H1 made of a heater or a planar heating element not shown are connected to the microcomputer U1, respectively.

아울러 건강 매트를 구동시키기 위한 전원 스위치(SW1)가 상기 마이컴(U1)에 접속되어 있으며, 상기 전원 스위치(SW1)의 스위칭 상태 및 발열부재(H1)의 동작에 따라 점등되도록 제1 및 제3 발광다이오드(LED1,LED3)가 상기 전원 스위치(SW1)에 병렬로 접속되어 있다.In addition, the power switch SW1 for driving the health mat is connected to the microcomputer U1, and the first and third light emission are turned on according to the switching state of the power switch SW1 and the operation of the heat generating member H1. Diodes LED1 and LED3 are connected in parallel to the power switch SW1.

한편, 건강 매트에 장착되는 미도시된 초장파 발생기(UW)를 구동시키기 위한 초장파 스위치(SW2)가 상기 마이컴(U1)에 접속될 수 있는데, 이 초장파 발생기(UW)의 구동상태를 사용자가 인지할 수 있도록 제2 발광다이오드(LED2)가 상기 초장파 스위치(SW2)에 병렬로 접속될 수 있다.On the other hand, the microwave switch (SW2) for driving the ultrasonic wave generator (UW) not shown mounted on the health mat may be connected to the microcomputer (U1), the user can recognize the driving state of the ultra-wave generator (UW). The second light emitting diode LED2 may be connected to the ultra long wave switch SW2 in parallel.

상기 마이컴(U1)은 스위치(SW1,SW2)와 엔코더(E1) 및 온도검출센서(S1,S2)의 출력신호에 따라 제1 및 제2 스위칭부(10,20)를 통해 발열부재(H1)나 초장파 발생기(UW)로 공급되는 전원(AC2)을 제어하여 상기 발열부재(H1)와 초장파 발생기(UW)의 구동을 제어한다.The microcomputer U1 generates heat through the first and second switching units 10 and 20 according to the output signals of the switches SW1 and SW2, the encoder E1 and the temperature detection sensors S1 and S2. (B) It controls the driving of the heat generating member H1 and the ultra long wave generator UW by controlling the power supply AC2 supplied to the ultra long wave generator UW.

즉, 상기 제1 및 제2 스위칭부(10,20)는 각각 트라이악(TR1)(TR2)과 트랜지스터(Q1)(Q2)로 구성되어 있는데, 상기 제1 및 제2 스위칭부(10,20)를 구성하는 트랜지스터(Q1)(Q2)의 베이스단에는 마이컴(U1)의 출력단이 각각 접속되어 있으며, 상기 트랜지스터(Q1)(Q2)의 베이스단은 접지되고 콜렉터단은 트라이악(TR1)(TR2)의 일측 단자에 각각 접속되어 있다.That is, the first and second switching units 10 and 20 are composed of triac TR1 and TR2 and transistors Q1 and Q2, respectively. The output terminal of the microcomputer U1 is connected to the base terminal of the transistors Q1 and Q2 constituting the circuit, respectively. The base terminal of the transistors Q1 and Q2 is grounded and the collector terminal is connected to the triac TR1 ( It is connected to one terminal of TR2), respectively.

또한, 상기 트라이악(TR1)(TR2)의 타측 단자에는 전원(AC1)이 인가되고 공통단자에는 초장파 발생기(UW)와 발열부재(H1)가 각각 접속되어 있다. 미설명된 도면부호 BD는 마이컴(U1)의 구동에 필요한 구동전원을 공급하는 정류부이고, BZ는 발열부재(H1)의 이상발열을 사용자에게 경고하기 위한 부저를 나타낸 것이다.In addition, a power source AC1 is applied to the other terminal of the triac TR1 and TR2, and an ultra-wave generator UW and a heat generating member H1 are connected to the common terminal, respectively. Unexplained reference numeral BD denotes a rectifier for supplying driving power required for driving the microcomputer U1, and BZ denotes a buzzer for warning the user of abnormal heat generation of the heat generating member H1.

다음에는 상기와 같이 구성된 본 발명에 따른 온도 조절 장치의 동작방법을 상세히 설명한다.Next, the operation method of the temperature control device according to the present invention configured as described above will be described in detail.

사용자가 건강 매트를 작동시키기 위해 전원 스위치(SW1)를 온시키면 이 전원스위치(SW1)에 병렬로 접속된 제1 발광다이오드(LED1)가 점등되고, 정류부(BD)에 의해 정류된 소정의 전압이 마이컴(U1)으로 인가됨에 따라 본 발명에 따른 온도 조절 장치는 발열부재(H1)를 제어할 수 있는 대기모드로 진입하게 된다.When the user turns on the power switch SW1 to operate the health mat, the first light emitting diode LED1 connected in parallel to the power switch SW1 is turned on, and the predetermined voltage rectified by the rectifying unit BD is turned on. As applied to the microcomputer U1, the temperature control device according to the present invention enters the standby mode for controlling the heating member H1.

이와같은 대기 모드 상태에서 사용자가 발열부재(H1)를 작동시키기 위해 15개 또는 그 이상의 접점을 갖는 온도조절용 엔코더(E1)를 회전시키면 마이컴(U1)이 이를 인식하고 그에따른 제어신호를 출력하게 된다. 즉, 엔코더(E1)로 부터 "H" 신호가 인가되면 마이컴(U1)은 일출력단을 통해 트랜지스터(Q2)의 베이스단으로 "H" 신호를 출력한다.In this standby mode, when the user rotates the temperature controlling encoder E1 having 15 or more contacts to operate the heating member H1, the microcomputer U1 recognizes this and outputs a control signal accordingly. . That is, when the "H" signal is applied from the encoder E1, the microcomputer U1 outputs the "H" signal to the base terminal of the transistor Q2 through one output terminal.

상기와 같이 베이스단으로 "H" 신호가 인가되면 트랜지스터(Q2)는 턴온되고 그에따라 트랜지스터(Q2)에 접속된 트라이악(TR2)도 턴온되어 전원선을 통해 인가되는 전원이 턴온된 트라이악(TR2)을 통해 발열부재(H1)로 인가된다. 따라서, 발열부재(H1)가 히팅되어 온열을 발생하게 된다.As described above, when the "H" signal is applied to the base terminal, the transistor Q2 is turned on, and accordingly, the triac TR2 connected to the transistor Q2 is also turned on to turn on the triac in which the power applied through the power line is turned on. TR2) is applied to the heat generating member (H1). Therefore, the heat generating member H1 is heated to generate heat.

한편, 제1 및 제2 온도검출센서(S1,S2)를 통해 검출된 발열부재(H1)의 온도가 엔코더(E1)를 통해 설정된 온도를 초과하면 마이컴(U1)은 트랜지스(Q2)의 베이스단으로 "L" 신호를 출력한다. 따라서, 트랜지스터(Q2)와 트라이악(TR2)가 순차적으로 턴오프되어 발열부재(H1)로 인가되는 전원을 차단시킴에 따라 발열부재(H1)의 온도를 일정하게 유지할 수 있다.On the other hand, if the temperature of the heat generating member H1 detected through the first and second temperature detection sensors S1 and S2 exceeds the temperature set by the encoder E1, the microcomputer U1 will base the transistor Q2. However, output the "L" signal. Therefore, the transistor Q2 and the triac TR2 are sequentially turned off to cut off the power applied to the heat generating member H1, thereby keeping the temperature of the heat generating member H1 constant.

상기와 같이 본 발명은 다단으로 구성된 엔코더의 출력에 따라 마이컴이 스위칭부를 제어하여 온열을 발생하는 히터 또는 면상발열체와 같은 발열부재로 전원을 공급 제어함에 따라 발열부재의 발열량을 단계적으로 가변할 수 있으며, 아울러 발열부재의 발열량을 사용자가 원하는 온도로 정확하게 조정할 수 있다.As described above, according to the present invention, the amount of heat generated by the heating element may be varied in step by controlling the power supply to a heating element such as a heater or a planar heating element that generates heat by controlling the switching unit according to the output of the encoder having a multi-stage. In addition, the calorific value of the heating member can be accurately adjusted to the temperature desired by the user.
