본 발명은 필요연소량에 따라 거버너 비례밸브와 온도조절용 전자밸브를 제어하는 가스연소장치에 관한 것이다.The present invention relates to a gas combustion device for controlling a governor proportional valve and a temperature regulating solenoid valve in accordance with a required combustion amount.
거버너 비례밸브와 온도조절용 전자밸브를 연설(連設)하여 이루어지는 가스공급로의 하류에 제1버너를 설치하고, 거버너 비례밸브와, 온도조절용 전자밸브와의 사이에서 분기하는 부 가스공급로의 하류에 제2버너를 설치하고, 대연소량이 필요한 경우에 온도조절용 전자밸브를 개방하고, 소연소량으로 좋은 경우는 온도조절용 전자밸브를 폐쇄함으로서, 엄동기에 넓은 실내를 충분히 난방할 수 있고, 또한 소 난방능력시에도 정확한 필요연소량이 얻어지는 FF식 난방기가 알려져 있다.The first burner is installed downstream of the gas supply passage formed by extending the governor proportional valve and the solenoid valve for temperature adjustment, and the downstream of the secondary gas supply passage branching between the governor proportional valve and the temperature regulating solenoid valve. By installing a second burner in the furnace and opening the solenoid valve for temperature control when a large combustion amount is necessary, and closing the solenoid valve for temperature control when the small amount of combustion is good, a large room can be sufficiently heated in the mower. FF type heaters are known in which the required amount of combustion is obtained even at heating capability.
이 FF식 난방기는, 구체적으로 제3도에 나타낸 바와 같이, 가스유속(=필요연소량)이 예를 들면 3속으로부터 4속의 필요유속으로 이행하는 경우, 온도조절용 전자밸브를 개방함과 동시에 비례밸브 전류를 일단 최저치(4속에 있어서의 전류치)를 향하여 감소시키고 있다.Specifically, as shown in FIG. 3, this FF heater has a proportional valve at the same time as opening the temperature regulating solenoid valve when the gas flow rate (= required combustion amount) shifts to a required flow rate from, for example, 3 to 4 speeds. The current is once reduced toward the lowest value (current value at four speeds).
또, 가스유속(=필요 연소량)이 4속으로부터 3속의 필요유속으로 이행하는 경우, 온도조절용 전자밸브를 폐쇄함과 동시에 거버너 비례밸브 전류를 일단 최대치(3속에 있어서의 전류치)를 향하여 증가시키고, 그 후, 필요유속에 적합한 값으로 감소시키고 있다.When the gas flow rate (= required combustion amount) shifts from the 4th speed to the 3rd speed required, the solenoid valve for temperature control is closed and the governor proportional valve current is increased to the maximum value (current value at 3 speed) once, Then, it reduces to the value suitable for a required flow rate.
FF식 난방기에서는, 버너에 연소용 공기를 공급하는 송풍기가 구비되어 있고, 이 송풍기는 회전수가 지시된 후 목표회전수가 되기까지, 기구상 다소 시간이 소요되기 때문에, 가스의 공급량을 제어하는 거버너 비례밸브는 송풍기의 회전수에 맞게 서서히 개방도를 변화시켜 갈 필요가 있다.In the FF type heater, a blower is provided for supplying combustion air to the burner, and the blower proportional to the governor for controlling the gas supply amount, because it takes some time from the mechanism until the target speed is reached after the rotation speed is indicated. The valve needs to gradually change the opening degree in accordance with the rotation speed of the blower.
또, 상기 송풍기가 없는 것에 있어서도 연소량을 변화시킬 때는, 연소상태를 안정시키기 위하여, 거버너 비례밸브의 개방도를 서서히 변화시켜 가는 것이 바람직하다.In addition, even when there is no blower, when changing the combustion amount, it is preferable to gradually change the opening degree of the governor proportional valve in order to stabilize the combustion state.
또한, 일반적으로 거버너 비례밸브는, 기구상에 있어서 목표의 개방도가 되기 까지에는 약간 시간이 소요되게 된다.Further, in general, the governor proportional valve takes some time to reach the target opening degree on the mechanism.
이 때문에, 가스유속을 3속으로부터 4속으로, 또는 4속으로부터 3속으로의 변형을 위해, 거버너 비례밸브에의 지시와 함께, 온도조절용 전자밸브를 개방 또는 폐쇄시키면, 3속으로부터 4속을 변화시키는 경우는, 전자밸브의 개방동작에 비하여 비례밸브의 개방도 감소가 지연되기 때문에, 단시가 가스리치가 되어 불완전연소를 일으키고, 4속으로부터 3속으로 변화하는 경우는, 전자밸브의 폐쇄동작에 비하여 거버너 비례밸브의 개방도 증가가 지연되기 때문에, 단시간 에어리치가 되어 실화가 생기기 쉽게 된다.For this reason, in order to deform the gas flow rate from 3rd speed to 4th speed or from 4th speed to 3rd speed, when the solenoid valve for temperature control is opened or closed with the instruction | indication to a governor proportional valve, the 3rd speed to 4th speed will be changed. In the case of a change, the decrease in the opening degree of the proportional valve is delayed compared with the opening operation of the solenoid valve. Therefore, when the short time becomes a gas value and causes incomplete combustion, the closing operation of the solenoid valve is changed from 4 speeds to 3 speeds. Compared with this, the opening degree of the governor proportional valve is delayed, so that it becomes a short time air rich and misfire easily occurs.
본 발명의 목적은, 필요연소량에 따라 거버너 비례밸브와, 온도 조절용 전자밸브를 제어하는 형식의 가스연소장치에 있어서, 온도조절용 전자밸브의 전환시에 연소 이상을 일으키지 않도록 하는데 있다.An object of the present invention is to prevent a combustion abnormality in switching between a governor proportional valve and a gas regulating valve for controlling a temperature regulating solenoid valve in accordance with a required combustion amount.
상기 과제를 해결하기 위하여 본 발명은, 비례밸브 전류에 알맞는 2차압이 발생하는 거버너 비례밸브에, 온도조절용 전자밸브를 연설하여 이루어지는 가스공급로의 하류에 설치된 제1버너와, 상기 거버너 비례밸브와 온도조절용 전자밸브와의 사이에서 분기하는 부가스공급로의 하류에 설치된 제2버너와, 필요연소량에 따라 상기 온도조절용 전자밸브의 개폐를 행함과 동시에, 필요연소량이 소정량 이하인 경우는, 제2버너만으로 필요연소량이 얻어지도록 상기 거버너 비례밸브에 통전하고, 필요연소량이 소정량을 초과하는 경우는 양버너로 필요연소량이 얻어지도록 상기 거버너 비례배브에 통전하는 연소제어수단을 구비하는 가스연소장치에 있어서, 상기 연소제어수단은, 상기 필요연소량이 상기 소정량을 초과하여 대연소량 측으로 이행하는 경우에는, 상기 거버너 비례밸브에 흐르는 비례밸브 전류를 상기필요연소량의 증가에 따라 증가하게 하고, 상기 필요연소량이 초과한 시점에서 비례밸브 전류를 일단 저하시키면서 하강 도중에 검출비례 밸브 전류가 소정치로 저하하면 상기 온도조절용 전자밸브를 개방시키고, 상기 필요연소량이 상기 소정량을 밑돌아 소연소량측으로 이행하는 경우에는, 상기 거버너 비례밸브에 흐르는 비례밸브 전류를 상기 필요연소량의 감소에 따라 감소시키고, 상기 필요연소량이 상기 소정량을 밑도는 시점에서 비례밸브 전류를 일단 저하시키면서 상승도중에 검출비례밸브 전류가 소정치로 증가하면 상기 온도조절용 전자밸브를 폐쇄시키는 구성을 채용했다.In order to solve the above problems, the present invention provides a first burner provided downstream of a gas supply path formed by extending a solenoid valve for temperature control to a governor proportional valve in which a secondary pressure suitable for proportional valve current is generated, and the governor proportional valve. And the second burner provided downstream of the auxiliary gas supply passage branching between the solenoid valve for controlling the temperature and the temperature regulating valve, and opening and closing the temperature regulating solenoid valve in accordance with the required combustion amount, A gas combustion device comprising combustion control means for energizing the governor proportional valve so that the required combustion amount is obtained only by two burners, and energizing the governor proportional valve so that the necessary combustion amount is obtained with both burners when the necessary combustion amount exceeds a predetermined amount. In the combustion control means, when the required combustion amount exceeds the predetermined amount and shifts to the large combustion amount side. When the proportional valve current flowing through the governor proportional valve increases as the required combustion amount increases, and the proportional valve current decreases to a predetermined value during the lowering while reducing the proportional valve current once the required combustion amount is exceeded. When the temperature regulating solenoid valve is opened and the required combustion amount is shifted to the small combustion amount side below the predetermined amount, the proportional valve current flowing through the governor proportional valve is reduced with the decrease in the required combustion amount, and the required combustion amount is decreased. The temperature control solenoid valve is closed when the proportional valve current decreases to a predetermined value while the proportional valve current is lowered at a time when the predetermined amount is lower than the predetermined amount.
필요연소량이 소연소량측으로부터 소정량을 초과하여 대연소량측으로 이행하는 경우, 필요연소량이 소정량에 달할 때까지는, 필요연소량의 증가에 따라, 거버너 비례밸브에 흐르는 비례밸브전류를 증가시켜 필요연소량이 소정량을 초과한 시점에서 비례밸브 전류를 일단 하강시켜 가고, 그 하강도중에서, 검출 비례밸브 전류가 소정치로 저하(가스리치)하면 온도조절용 전자밸브를 개방시킨다. 그리고, 온도조절용 전자밸브를 개방 유지한 상태에서 비례밸브 전류를 필요연소량에 알맞은 값으로 증가시킨다.In the case where the required combustion amount exceeds the predetermined amount from the small combustion amount side to the large combustion amount side, until the required combustion amount reaches the predetermined amount, as the required combustion amount increases, the proportional valve current flowing through the governor proportional valve increases and the required combustion amount is increased. The proportional valve current is once lowered at a time when the predetermined amount is exceeded, and the temperature regulating solenoid valve is opened when the detection proportional valve current drops to a predetermined value (gas rich) during the lowering degree. Then, the proportional valve current is increased to a value appropriate to the required combustion amount while the solenoid valve for temperature control is kept open.
필요연소량이 대연소량측으로부터 소정량을 밑돌아 소연소량측으로 이행하는 경우, 필요연소량이 소정량에 이르기까지는, 필요연소량의 감소에 따라 거버너 비례밸브에 흐르는 비례밸브 전류를 줄여가고, 필요연소량이 소정량을 밑도는 시점에서 비례밸브 전류를 일단 상승시켜 가고, 그 상승온도중에서 검출 비례밸브 전류가 소정치로 증가(에어리치)하면, 온도조절용 전자밸브를 폐쇄시킨다. 그리고, 전자밸브를 폐쇄 유지한 상태에서 비례밸브 전류를 필요연소량에 알맞은 값으로 감소시킨다.When the required combustion amount is shifted from the large combustion amount side to the small combustion amount side by a predetermined amount, until the required combustion amount reaches a predetermined amount, the proportional valve current flowing through the governor proportional valve decreases as the required combustion amount decreases, and the required combustion amount is a predetermined amount. When the proportional valve current is raised at a time lower than, and the detection proportional valve current increases (air value) to a predetermined value during the rising temperature, the solenoid valve for temperature control is closed. Then, the proportional valve current is reduced to a value suitable for the required combustion amount while the solenoid valve is kept closed.
필요연소량이 소연소량측으로부터 소정량을 초과하여, 대연소량측으로 이행하는 경우에는, 거버너 비례밸브의 개방도 감소 타이밍과 온도조절용 전자밸브의 개방동작이 대략 정합하여 가스리치가 방지되고, 필요연소량이 대연소량측으로부터 소정량을 밑돌아 소연소량측으로 이행하는 경우에는, 거버너 비례밸브의 개방도 증가타이밍과, 온도조절용 전자밸브의 폐쇄동작이 대략 정합하여 에어리치를 방지할 수 있다.When the required combustion amount exceeds the predetermined amount from the small combustion amount side and shifts to the large combustion amount side, the timing of opening of the governor proportional valve decreases and the opening operation of the solenoid valve for temperature regulation are roughly matched to prevent gas retreat. In a case where the predetermined amount is shifted from the large combustion amount side to the small combustion amount side, the increase in timing of opening of the governor proportional valve and the closing operation of the solenoid valve for temperature regulation are substantially matched to prevent the air rich.
이로 인하여 필요연소량에 따라 온도조절용 전자밸브의 개폐를 행함과 동시에, 필요연소량이 소정량 이하인 경우는 제2버너만으로 필요연소량이 얻어지도록 거버너 비례밸브에 통전되고, 필요연소량이 소정량을 초과하는 경우는 양 버너로 필요연소량이 얻어지도록 거버너 비례밸브에 통전되는 가스연소장치에 있어서, 온도조절용 전자밸브의 전환시에 발생하기 쉬웠던 연소이상을 방지할 수가 있게 된다.For this reason, the solenoid valve for temperature control is opened and closed according to the required combustion amount, and when the required combustion amount is less than the predetermined amount, the governor proportional valve is energized so that the required combustion amount is obtained only by the second burner, and the required combustion amount exceeds the predetermined amount. In the gas combustion device which is energized by the governor proportional valve so that the required combustion amount can be obtained by both burners, it is possible to prevent the combustion abnormality that was likely to occur when the solenoid valve for temperature control is switched.

제1도에 나타낸 바와 같이, FF식 난방기(A)는 상류측으로부터 제1전자밸브(11), 제2전자밸브(12), 거버너 비례밸브(13) 및 온도조절용 전자밸브(14)를 연설하여 이루어지는 가스공급로(2)의 하류에 설치되는 제1버너(3)와, 거버너 비례밸브(13)와 온도조절용 전자밸브(14)와의 사이에서 분기하는 부가스공급로(21)의 하류에 설치되는 제2버너(4)와, 온도조절용 전자밸브(14)의 개폐, 거버너 비례밸브(13), 연소용팬(51), 대류용팬(52)에의 통전, 스파크전극(53)의 작동 등을 제어하는 연소제어기(6)를 가진다. 또한, 110은 실내공기(S)와 연소가스(N)가 열교환하는 열교환기, 120은 연소가스를 실외로 배출하는 배기덕트, 54는 더모커플, 71은 운전스위치, 72는 실내온도 설정기이다.As shown in FIG. 1, the FF heater A extends the first solenoid valve 11, the second solenoid valve 12, the governor proportional valve 13, and the temperature regulating solenoid valve 14 from the upstream side. Downstream of the first burner 3 provided downstream of the gas supply passage 2 formed therebetween, and the auxiliary gas supply passage 21 branching between the governor proportional valve 13 and the temperature regulating solenoid valve 14. Opening / closing of the second burner 4, the temperature regulating solenoid valve 14, governor proportional valve 13, the combustion fan 51, the convection fan 52, the operation of the spark electrode 53, etc. It has a combustion controller 6 for controlling. In addition, 110 is a heat exchanger for heat exchange between indoor air (S) and combustion gas (N), 120 is an exhaust duct for discharging combustion gas to the outside, 54 is a thermocouple, 71 is an operation switch, and 72 is an indoor temperature setter. .
거버너 비례밸브(13)는 비례밸브 전류가 흐르면, 그 비례밸브전류에 알맞는 2차압이 발생하는 밸브이다.The governor proportional valve 13 is a valve which generates a secondary pressure suitable for the proportional valve current when the proportional valve current flows.
온도조절용 전자밸브(14)는, 통전에 의하여 개방되는 밸브로서, 개방되는 경우 제1버너(3)에 가스가 공급되어 제1버너(3) 및 제2버너(4)에 가스가 공급되며, 폐쇄되는 경우에는 제1버너(3)에의 가스공급이 정지되므로 제2버너(4)에만 가스가 공급되게 된다.The temperature regulating solenoid valve 14 is a valve opened by energization, and when opened, gas is supplied to the first burner 3 and gas is supplied to the first burner 3 and the second burner 4, When the gas is closed, the gas supply to the first burner 3 is stopped, so that the gas is supplied only to the second burner 4.
재1버너(3)는, 연소실(100)의 아래쪽 외주측에 설치된 연소플레이트에 의하여 구성되고, 필요연소량이 소정량을 초과하는 경우에 온도조절용 전자밸브(14)가 개발되고, 가스가 공급되어 연소한다.The first burner 3 is constituted by a combustion plate provided on the lower outer side of the combustion chamber 100, and when the required combustion amount exceeds a predetermined amount, a solenoid valve for temperature control 14 is developed, and gas is supplied. Burn out.
제2버너(4)는 연소실(100)의 아래쪽 내주측에 설치된 연소 필요연소량에 의하여 구성되고, 필요연소량이 소정량 이하인 경우, 즉 온도조절용 전자밸브(14)가 폐쇄되어 있어도 제1전자밸브(11) 및 제2전자밸브(12)가 개방되어 있으면 가스가 공급되어 연소한다.The second burner 4 is constituted by the combustion required combustion amount provided on the lower inner circumferential side of the combustion chamber 100, and when the required combustion amount is less than or equal to a predetermined amount, that is, even when the temperature regulating solenoid valve 14 is closed, the first solenoid valve ( 11) and the second solenoid valve 12 is opened, gas is supplied and burned.
연소용팬(51)은 모터(511) 및 날개(512)를 구비함과 동시에, 연소제어기(6)에 의하여 후기하는 필요 연소량에 의거하여 전류가 흐르게 되어 회전하고, 실내공기(S)를 흡인하여 혼합실(31,41)에 공급한다.The combustion fan 51 is provided with a motor 511 and a blade 512, and rotates as a current flows based on the required amount of combustion, which is later described by the combustion controller 6, and sucks the indoor air S. It is supplied to the mixing chambers 31 and 41.
대류용 팬(52)은, 모터(521) 및 날개(522)를 구비함과 동시에, 연소제어기(6)에 의하여 후기하는 필요연소량에 의거하여 전류가 흘러 회전하고, 실내공기(S)를 흡인하여 온풍기류(K)를 발생시킨다.The convection fan 52 includes a motor 521 and a blade 522, and a current flows and rotates based on a required combustion amount, which is later described by the combustion controller 6, and sucks the indoor air S. To generate a warm airflow (K).
연소제어기(6)는, 마이크로컴퓨터(61)를 구비하고, 더미스터(도시생략)에 의하여 검출되는 실온과 실온설정기(72)로 설정되는 목표치와의 차에 의거하여 연산한 필요연소량(가스유속이 1속 내지 8속)에 따라 온도 조절용 전자밸브(14)의 개폐, 및 거버너 비례밸브(13)의 제어를 행한다. 예를 들면, 가스유속이 1속 내지 3속까지는 온도조절용 전자밸브(14)가 폐쇄함과 동시에, 제2버너(4)만으로 필요연소량이 얻어지도록 거버너 비례밸브(13)에 통전하고, 가스유속이 4속 이상인 경우는, 온도조절용 전자밸브(14)가 개방됨과 동시에 양 버너로 필요연소량이 얻어지도록 거버너 비례밸브(13)에 통전한다. 또한, 소정량은 본 실시예의 경우, 연소량이 증가할 때는 3속의 가스유속이고, 연소량이 감소할 때는 4속의 가스유속이다.The combustion controller 6 includes a microcomputer 61, and calculates the required combustion amount (gas based on the difference between the room temperature detected by the dummyster (not shown) and the target value set by the room temperature setter 72). According to the flow rate of 1 to 8 speeds, the opening and closing of the solenoid valve 14 for temperature regulation and the governor proportional valve 13 are controlled. For example, when the gas flow rate is 1 to 3 speeds, the solenoid valve 14 for temperature control is closed and the governor proportional valve 13 is energized so that the required combustion amount is obtained only by the second burner 4, and the gas flow rate is maintained. In the case of four speeds or more, the governor proportional valve 13 is energized so that the temperature regulating solenoid valve 14 is opened and the required combustion amount is obtained by both burners. In addition, in the present embodiment, the predetermined amount is a gas flow rate of three speeds when the combustion amount increases, and a gas flow rate of four speeds when the combustion amount decreases.
본 실시예에 있어서의 온도조절용 전자밸브(14)의 전환의 상세함을 제2도와 함께 설명한다.The details of the switching of the temperature regulating solenoid valve 14 in this embodiment will be described together with FIG.
(a) 필요연소량이 증가하는 경우(a) the amount of combustion required increases;
마이크로컴퓨터(61)가 가스유속(=필요연소량)을 1속~3속의 어느 하나를 지정했을 경우는, 온도조절용 전자밸브(14)가 폐쇄상태로 유지되고, 제2버너(4)만으로 필요연소량이 얻어지도록 통전전류가 거버너 비례밸브(13)에 흐르게 한다.When the microcomputer 61 designates the gas flow rate (= required combustion amount) in one of 1 speed and 3 speeds, the solenoid valve 14 for temperature control is kept closed, and the required combustion amount only with the second burner 4. An energized current flows to the governor proportional valve 13 so that this may be obtained.
가스유속이 3속인 경우에 있어서, 마이크로컴퓨터(61)가 4속을 지정했을 경우는, 그 지정이 있었던 시점에서 비례밸브 전류를 최저치(4속에 있어서의 전류치)를 향하여 감소시키고, 감소의 순간부터 소정시간 지연하여, 비례밸브 전류가 하강하는 도중에서 온도조절용 전자밸브(14)를 개방한다.In the case where the gas flow rate is three speeds, when the microcomputer 61 designates four speeds, the proportional valve current is reduced toward the lowest value (current value in four speeds) at the time when the designation is made, and from the moment of decrease. At a predetermined time delay, the temperature regulating solenoid valve 14 is opened while the proportional valve current falls.
(b)필요연소량이 감소하는 경우(b) the amount of burning required decreases;
마이크로컴퓨터(61)가 가스유속을 4속 내지 8속 중 어느 하나를 지정한 경우는, 온도조절용 전자밸브(14)가 개방상태로 유지되고, 양버너에 의하여 필요연소량이 얻어지도록 통전전류가 거버너 비례밸브(13)에 흐르게 된다.When the microcomputer 61 designates a gas flow rate of 4 to 8 speeds, the energizing current is proportional to the governor so that the solenoid valve 14 for temperature control is kept open and the required combustion amount is obtained by both burners. It flows into the valve 13.
가스유속이 4속인 경우에 있어서, 마이크로컴퓨터(61)가 3속을 지정한 경우는, 그 지정이 있었던 시점에서 비례밸브 전류가 최대치(3속에 있어서의 전류치)를 향하여 증대시켜, 증대의 순간부터 소정시간 지연하여 온도조절용 전자밸브(14)를 폐쇄한다.In the case where the gas flow rate is 4 speeds, when the microcomputer 61 designates 3 speeds, the proportional valve current increases toward the maximum value (current value at 3 speeds) at the time point of the designation, and is determined from the moment of increase. The temperature regulating solenoid valve 14 is closed by time delay.
다음에 FF식 난방기(A)의 이점을 기술한다.Next, the advantages of the FF heater A will be described.
(a) 가스유속이 3속으로부터 4속으로 이행하는 경우에는, 거버너 비례밸브(13)의 개방도 감소 타이밍과 온도조절용 전자밸브(14)의 개방동작이 대략 정합하여 가스리치를 방지할 수 있고, 가스유속이 4속으로부터 3속으로 이행하는 경우에는 거버너 비례밸브(13)의 개방도 증대 타이밍과 온도저절용 전자밸브(14)의 폐쇄동작이 정합하여 에어리치를 방지할 수 있다.(a) When the gas flow rate is shifted from 3 speeds to 4 speeds, the timing of opening of the governor proportional valve 13 and the opening operation of the temperature regulating solenoid valve 14 are substantially matched to prevent gas rich. When the gas flow rate is shifted from the fourth speed to the third speed, the opening degree of the governor proportionality valve 13 is increased and the closing operation of the temperature saving solenoid valve 14 is matched to prevent the air rich.
이 때문에, 온도조절용 전자밸브(14)의 전환시에 발생하기 쉬웠던 연소이상을 방지할 수 있다.For this reason, the combustion abnormality which was easy to occur at the time of switching of the thermostat solenoid valve 14 can be prevented.
(b) 마이크로컴퓨터(61)가 가스유속을 3속으로부터 4속, 또는 4속으로부터 3속으로 전환지시를 낸 후, 소정시간 지연시켜서 온도조절용 전자밸브(14)를 개방 또는 폐쇄시킨다고 하는 간단한 구성이기 때문에 제조비용을 현저하게 증대시키지 않는다.(b) A simple configuration in which the microcomputer 61 switches the gas flow rate from three speeds to four speeds or from four speeds to three speeds, and then delays the predetermined time to open or close the solenoid valve 14 for temperature control. This does not significantly increase the manufacturing cost.
본 발명은, 상기 실시예 이외에 다음의 실시상태를 포함한다.The present invention includes the following embodiments in addition to the above embodiments.
(a) 상기 실시예에서는 비례밸브 전류를 감소, 또는 증대시킨 순간부터 소정시간 지연시켜 온도조절용 전자밸브를 개방 또는 폐쇄시키고 있으나, 비례밸브 전류를 검출하고, 검출한 비례밸브 전류의 하강도중 또는 상승도중에 있어서 소정의 전류치에 달했을 때 온도조절용 전자밸브 개방 또는 폐쇄하도록 하여도 좋다.(a) In the above embodiment, the solenoid valve for temperature control is opened or closed by delaying a predetermined time from the moment when the proportional valve current is decreased or increased, but the proportional valve current is detected and the detected proportional valve current is lowered or raised. When the predetermined current value is reached along the way, the solenoid valve for temperature control may be opened or closed.
(b) 상기 실시예에서는 제1버너는 2개, 제2버너는 1개이나, 각 버너의 수는 임의적이다.(b) In the above embodiment, there are two first burners and one second burner, but the number of burners is arbitrary.
(c) 비례밸브 전류의 감소시와 증대시에 있어서, 각 지연시간 또는 전류치를 각각 다르게 하여도 좋다.(c) When the proportional valve current decreases or increases, the respective delay time or current value may be different.
(d) 상기 실시예에서는 가스유속은 8스텝의 분산치이나, 연속적으로 변화시켜도 좋다.(d) In the above embodiment, the gas flow rate is 8 steps of dispersion value, but may be changed continuously.
(e) 상기 실시예에서는 가스연소장치는 FF식 난방기이나, 본 발명의 구성을 가스급탕기, 가스취사기, 가스조리기, 가스스토브, 가스오븐, 가스건조기 등에 응용하여도 좋다.(e) In the above embodiment, the gas combustion device is an FF heater, but the configuration of the present invention may be applied to a gas water heater, a gas cooker, a gas cooker, a gas stove, a gas oven, a gas dryer, or the like.
