いという問題があつた。Conventional examples, configurations, and their problems In recent years, as houses have become more airtight, accidents due to lack of oxygen in indoor open combustion equipment such as stoves, fan heaters, and water heaters have increased, and the installation of safety devices has become commonplace. Currently, there are many safety devices of this type that automatically stop combustion after learning about incomplete combustion, or that operate a ventilation fan at the same time as the appliance is used. The former is often used in fan heaters, stoves, etc., but if it is extinguished while the room is being heated, it will become cold, and people will need to open windows to ventilate the room. The latter has a configuration as shown in FIG. FIG. 7 takes the gas instantaneous water heater 1 as an example. A switch (not shown) operates in conjunction with the ignition knob 2 to rotate the ventilation fan 3, and when the knob 2 is stopped, the ventilation fan 3 rotates. The structure is such that it also stops rotating. In this case, there is no problem with devices that are only used for a short period of time, such as instantaneous water heaters, but if a ventilation fan operates while a heating device such as a stove or fan heater is in use, the heating effect decreases and there is a problem in that energy savings are not achieved.

The side electrode of the aforementioned zirconia oxygen concentration sensor 6 is connected to the negative input terminal of the detection circuit 7 (an inverting amplifier is formed by the operational amplifier 21 and resistors 22 and 23), and the side electrode of the sensor is connected to the positive input terminal of the operational amplifier 21. is connected to comparator 2, and its output is connected to comparator 2.

いでいる。 Also, the phototransistor 10 is connected to the DC power supply 25.
(receiving section) is connected, and the signal from the light emitting diode 9 is received by the receiving circuit 11. Further, the receiving circuit 11 checks the digital signal received by the phototransistor 10, and when it is a normal signal, sets the output 〓d to high. Comparator 34 of timer circuit 33
A potential f obtained by dividing the potential d by resistors 35 and 36 is input to the negative input terminal of the circuit, and a potential g obtained by dividing the potential d by a resistor 37 and a capacitor 38 is input to the positive input terminal. When the potential 〓d becomes a high output, the capacitor 38 is not charged, so 〓f
＞〓g, the output 〓h becomes low, the relay 29 becomes conductive, and the fan motor 14 rotates. When the capacitor 38 is charged and the potential becomes 〓g〓〓f, the fan motor 14 stops. In other words, the fan motor 14 is configured to rotate for a certain period of time in response to a signal from the receiving section 11, thereby preventing a drop in the room temperature due to heating or the like. (Instead of the timer device 33, the stop signal for the fan motor 14 may be output from the transmitter 9.)
Further, the transmitter circuit 8 and the receiver circuit 11 use digital signals to prevent malfunctions due to noise from other light sources.

サ６の出力はほとんど零であり検出回路７の出力
は〓ａと導電位となる。電位〓ａ＞〓ｂであるた
めコンパレータ２４の出力はロー出力となる。 Normally, when the burner 5 is burning normally, the output of the sensor 6 is almost zero, and the output of the detection circuit 7 becomes 〓a, which is a conductive potential. Since the potential 〓a>〓b, the output of the comparator 24 becomes a low output.

９はこの信号に応じて点滅する。 The transmitting circuit 8 does not operate when the output of the comparator 24 is low, but outputs a predetermined digital signal when the output is high, and the sending diode 9 blinks in response to this signal.
ここで室内の酸素欠乏によりバーナ５が不完全
燃焼になつたとき、センサ７は約0.8Vの起電力

となり電位〓ａよりも低下する。このため〓ａ＜
〓ｂとなりコンパレータ２４の出力はハイ出力と
なり発振回路８を通して発光バイオード９に電流
が流れ発光する。 When the burner 5 undergoes incomplete combustion due to lack of oxygen in the room, the sensor 7 generates an electromotive force 〓s of about 0.8V. Since the detection circuit 7 inverts and amplifies this, the output 〓o is 〓a-(1+R 23 /R 22 )・〓s
Therefore, the potential becomes lower than the potential 〓a. For this reason 〓a＜
〓b, the output of the comparator 24 becomes a high output, and a current flows to the light emitting biode 9 through the oscillation circuit 8, causing it to emit light.

ある。 Further, the output of the comparator 24 is simultaneously input to the safety circuit 32. The safety circuit 32 constitutes a timer circuit using a comparator 39, and when the comparator 24 outputs a low output (during normal combustion), the output h becomes a low output, and the valve 31 becomes conductive to send gas to the burner 5. Here, when the output of the comparator 24 becomes high, the resistor 40 and capacitor 41
The divided potential of resistors 42 and 43 is the divided potential of resistors 42 and 43
It was lower than , but capacitor 41 was charged.
Since i>〓j, the output 〓h becomes a high output. As a result, the valve 31 is de-energized, gas is no longer supplied to the burner, and the burner 5 is extinguished. At this time, a buzzer or the like may be used to notify the user. In other words, the burner 5 is extinguished when the combustion condition is not improved even after a certain period of time has elapsed since the ventilation system 12 was activated.

The light emitting section 9 and the light receiving section 10 are set at a wide angle using a lens or the like, making it possible to drive the ventilation system 12 no matter where the fan heater 30 is placed in the room. Here, the ventilation device 12 is explained as a wall-mounted ventilation fan, but a duct-type ventilation fan has exactly the same effect.

Ventilation is possible by signals from a plurality of devices such as the instantaneous water heater 45, and it is safe even when a plurality of combustion devices are used in the same room. Further, if one ventilation device 12 is provided in each room, it is safe because the ventilation device in the room will operate no matter where a movable combustion device such as a stove or a fan heater is placed.

A burner section that discharges combustion exhaust into the room for combustion, a sensor that detects the combustion state of the burner section, and a detection circuit that detects incomplete combustion of the burner section based on the output of the sensor and outputs a predetermined signal. A combustion device consisting of a transmitting circuit that converts the signal and sends the signal into the air from the transmitter, a receiver that receives the signal from the transmitter, and a fan that converts the signal from the receiver to rotate the fan that ventilates indoor air. a ventilation device including a reception circuit that outputs a signal, the ventilation device having a timer device that rotates the fan for a certain period of time after the reception section receives the signal, and then stops the fan, and the combustion equipment includes the detection circuit. A safety device for combustion equipment that is equipped with a safety circuit that stops combustion in the burner section if incomplete combustion continues even after a certain period of time has passed after the transmission section sends a drive signal for the ventilation system.
