It relates to a temperature-sensing temperature control device using a heating wire to calculate the temperature and to control the temperature of the heat transfer mat device using the calculated temperature.

최근 전력의 사용이 편리하고 온도 상승이 빠를 뿐만 아니라 그 온도조절이 용이하기 때문에 전력을 이용하여 발열되는 전열 매트나 전열 카페트와 같은 전열 매트 장치의 사용이 증가되고 있다.In recent years, the use of electric power mats, such as heat transfer mats or heat transfer carpets that generate heat by using electric power, is increasing due to the ease of use of electric power and the rapid rise of temperature.

일반적으로 전열 매트 장치에는 내부에 전열선이 배선되고 그 전열선으로 전류를 흘려 발열된다. 상기와 같은 전열 매트 장치에는 온도를 적정하게 유지할 수 있도록 온도조절장치가 구비된다. 일반적으로 온도조절은 전열 매트 장치의 온도를 측정하고 그 측정된 온도에 따라 전열선으로의 전력의 공급을 제어함으로써 이루어진다.In general, a heating wire is wired inside the heating mat device, and a current flows through the heating wire to generate heat. The heat transfer mat device as described above is provided with a temperature control device to properly maintain the temperature. In general, temperature control is achieved by measuring the temperature of the heating mat device and controlling the supply of power to the heating wire in accordance with the measured temperature.

도 1 및 도 2는 종래의 온도조절장치가 구비된 전열 매트 장치의 예를 도시한 사시도이다.1 and 2 is a perspective view showing an example of a heat transfer mat device equipped with a conventional temperature control device.

도 1에 도시된 종래의 전열 매트 장치(1)에서는 온도조절장치(3)가 온도센서(4)를 전열선(2) 사이에 매설시키고 그 온도센서(4)로부터 측정된 온도를 이용하여 온도를 조절한다.In the conventional heat transfer mat device 1 shown in FIG. 1, the temperature control device 3 embeds the temperature sensor 4 between the heating wires 2 and uses the temperature measured from the temperature sensor 4 to adjust the temperature. Adjust

도 2에 도시된 종래의 전열 매트 장치(5)에서는 전열선(6)을 따라 온도감지용 전선(8)을 배선시키고 온도에 따라 그 온도감지용 전선(8)에 흐르는 전류로부터 온도를 산출하고, 그 산출된 온도에 따라 온도조절장치(7)가 온도를 조절한다.In the conventional heat transfer mat device 5 shown in FIG. 2, the temperature sensing wire 8 is wired along the heating wire 6, and the temperature is calculated from the current flowing in the temperature sensing wire 8 according to the temperature. The temperature control device 7 adjusts the temperature in accordance with the calculated temperature.

그러나, 도 1의 종래의 온도조절장치는 온도센서에 의해 감지되는 온도는 온도센서가 설치된 위치만의 온도가 반영되지만 다른 위치의 온도는 무시된다. 이는 온도센서가 설치되지 않은 위치에서는 온도가 계속 상승하여 종국에는 화재가 발생되는 위험성이 있다.However, in the conventional temperature controller of FIG. 1, the temperature detected by the temperature sensor reflects only the temperature at which the temperature sensor is installed, but the temperature at other positions is ignored. This is a danger that the temperature continues to rise in the position where the temperature sensor is not installed, and eventually fire occurs.

한편, 도 2에 도시된 종래의 온도조절장치는 도 1에 도시된 온도조절장치가 갖는 단점을 갖지 않는다. 그러나 도 2에 도시된 종래의 온도조절장치는 별도의 온도감지용 전선이 구비되어 배선되어야 하기 때문에 가격이 상승될 뿐만 아니라 온도감지용 전선의 배선에 따른 제작이 어려운 단점을 갖는다.On the other hand, the conventional thermostat shown in Figure 2 does not have the disadvantages that the thermostat shown in FIG. However, the conventional temperature control device shown in FIG. 2 has a disadvantage in that it is difficult to manufacture according to the wiring of the temperature sensing wire as well as the price increases because a separate temperature sensing wire is to be provided and wired.

도 3은 본 발명의 일실시예에 따른 전열선을 이용한 온도감지형 온도조절장치의 구성을 도시한 구성도이다.Figure 3 is a block diagram showing the configuration of a temperature-sensing temperature control device using a heating wire according to an embodiment of the present invention.

본 발명은 발열을 위한 전열선(22)이 내부에 배선된 전열 매트 장치(21)의 온도를 조절하기 위한 것이다. 전술한 내용 및 후술하는 내용에서 전열 매트 장치(21)는 전열 매트, 전열 카페트, 전기 담요, 전기 침대 등과 같이 사용자가 바닥에 깔거나 사용자가 덮을 수 있고 그 내부에 전열로 발열시킬 수 있도록 전열선이 배선된 장치 또는 이와 유사한 장치를 말한다.The present invention is to adjust the temperature of the heat transfer mat device 21 in which the heating wire 22 for heat generation is wired therein. In the above description and the following description, the heating mat device 21 has a heating wire such that the heating wire can be laid by the user or covered by the user, such as a heating mat, a heating carpet, an electric blanket, an electric bed, and the like. Refers to a wired device or similar device.

도면을 참조하면 본 발명의 일실시예에 따른 전열선을 이용한 온도감지형 온도조절장치(10)는 전류측정부(11)와, 온도산출부(12), 및 제어부(13)로 구성된다.Referring to the drawings, the temperature sensing temperature control apparatus 10 using a heating wire according to an embodiment of the present invention includes a current measuring unit 11, a temperature calculating unit 12, and a control unit 13.

상기 전류측정부(11)는 상기 전열선(22)에 흐르는 전류량을 측정하기 위한 것이다. The current measuring unit 11 is for measuring the amount of current flowing in the heating wire (22).

상기 온도산출부(12)는 상기 전류측정부(11)에 의해 측정된 전류값을 전달받아 그 전류값으로부터 온도를 산출하기 위한 것이다. 즉, 상기 온도산출부(12)는 상기 전류측정부(11)에 의해 측정된 전류값을 기설정된 온도 대비 전류값과의 관계(F)에 따라 전열 매트 장치의 온도를 산출하여 상기 제어부(13)로 전달한다. 도 4는 전열선의 온도 대비 전류값과의 관계(F)의 일례를 도시한 것이다. 일반적으로 상기 전열선(22)에는 전열선(22)의 온도가 상승할수록 전류가 낮아진다. 상기와 같은 온도 대비 전류값과의 관계(F)는 전열선(22)의 저항, 길이 등에 따라 달라지며, 그러한 관계(F)를 수학적으로 계산하여 산출하기는 매우 어렵다. 따라서, 본 발명은 온도 대비 전류값과의 관계(F)를 실험적으로 구하는 것이 바람직하다. 즉, 제작된 전열 매트 장치(21)에서 전열선(22)이 균일하게 온도가 상승되도록 조건을 설정한 다음 전열선으로 전류를 흘려 소정의 온도측정장치(15)로 전열 매트 장치(21)에서 변화되는 온도(T1,T2,T3,T4)를 측정하고, 그 측정된 각각의 온도(T1,T2,T3,T4)에서 상기 전열선(22)으로 흐르는 전류(I1,I2,I3,I4)를 측정하여 온도 대비 전류값과의 관계(F)는 측정된 온도(T1,T2,T3,T4)와 전류(I1,I2,I3,I4)로부터 산출된다.The temperature calculation unit 12 receives a current value measured by the current measuring unit 11 and calculates a temperature from the current value. That is, the temperature calculating unit 12 calculates the temperature of the heat transfer mat device based on the relationship F between the current value measured by the current measuring unit 11 and the current value compared with the preset temperature, and controls the control unit 13. To pass). 4 shows an example of the relationship (F) with the current value versus the temperature of the heating wire. In general, as the temperature of the heating wire 22 increases, the heating wire 22 has a lower current. The relationship F with the temperature-to-current value as described above depends on the resistance, the length, etc. of the heating wire 22, and it is very difficult to calculate and calculate the relationship F mathematically. Therefore, in the present invention, it is preferable to experimentally obtain the relationship (F) with respect to the current value versus temperature. That is, the condition is set so that the heating wire 22 is uniformly raised in the heat transfer mat device 21, and then the electric current flows through the heat transfer wire, which is changed from the heat transfer mat device 21 to the predetermined temperature measuring device 15. Measure the temperature (T1, T2, T3, T4), and measure the current (I1, I2, I3, I4) flowing to the heating wire 22 at each of the measured temperatures (T1, T2, T3, T4) The relationship F between the temperature and the current value is calculated from the measured temperatures T1, T2, T3, T4 and the currents I1, I2, I3, I4.

상기 제어부(13)는 상기 전열 매트 장치(21)의 온도를 조절하도록 상기 온도산출부(12)에 의해 산출된 측정온도와 사용자가 입력하여 미리 설정된 기준온도에 따라 전열선(22)으로의 전력의 공급을 제어하고, 상기 전류측정부(11) 및 온도산출부(12)의 작동을 제어한다. 일반적으로 상기 전열선(22)의 온도가 상승되어 흐르는 전류가 변화되면 전압이 상승된다. 전압이 변하면 온도 대비 전류값과의 관계(F)가 복잡해진다. 따라서 본 발명은 상기 제어부(13)에 상기 전열선(22)을 흐르는 전류의 전압을 일정하게 유지시키기 위한 정전압회로가 구비되는 것이 바람직하다. 한편, 전류가 상승되거나 하강되면 온도조절이 세밀하게 이루어지는 것이 바람직하다. 따라서, 상기 제어부(13)는 측정온도가 설정온도와 가까워지면 상기 전류측정부(11)와 온도산출부(12)의 작동주기를 증가시키고, 그에 따라 온도를 조절하는 것이 바람직하다.The control unit 13 controls the temperature of the electric heating wire 22 according to the measured temperature calculated by the temperature calculating unit 12 and the user inputted reference temperature to adjust the temperature of the heat transfer mat device 21. The supply is controlled, and the operation of the current measuring unit 11 and the temperature calculating unit 12 is controlled. In general, when the temperature of the heating wire 22 rises and the current flowing therein, the voltage increases. When the voltage changes, the relationship (F) to the current value versus temperature becomes complicated. Therefore, in the present invention, the control unit 13 is preferably provided with a constant voltage circuit for maintaining a constant voltage of the current flowing through the heating wire (22). On the other hand, it is preferable that the temperature is finely controlled when the current is increased or decreased. Therefore, the control unit 13 increases the operating cycle of the current measuring unit 11 and the temperature calculating unit 12 when the measured temperature is close to the set temperature, it is preferable to adjust the temperature accordingly.
