である。[Detailed Description of the Invention] Industrial Application Field The present invention is an open combustion hot air heater that uses gas, oil, etc. as fuel, and notifies ventilation of indoor air at the optimal timing for the indoor environment in which it is used. It's something that flashes into the controller.

出して、燃焼を停止させるものが一般的であった。Conventional technology Combustion type hot air heaters such as fan heats burn indoors, so ventilation of indoor air is essential. Conventionally, when incomplete combustion occurs due to a decrease in oxygen concentration, a flame rod inserted into the burner flame detects a change in the ionic current of the flame to stop combustion.

抗８で検出する。This configuration will be explained in FIG. 4. Burning gas is ejected from a nozzle 1, mixed with air through a mixing tube 2, forms a flame 5 inside a combustion plate 3 formed of a wire mesh, and burns. A flame rod 6 is inserted into the flame 5, and a DC power source 7 is applied between it and the combustion plate 3, and the ionic current I of the flame is detected by a resistor 8.

内の酸素濃度が低下すれば炎電流１１は上昇して行く。The voltage drop across the resistor 80 is proportional to the flame current 11, and when this output is below or above a certain threshold, the burner is judged to be in abnormal combustion and is cut off, cutting off the fuel supply. Stop and extinguish the fire. Figure @5 shows this characteristic. The horizontal axis shows the indoor oxygen concentration, and the vertical axis shows the flame current I (and carbon monoxide (Co) generated from the burner) in relative values. As the indoor oxygen concentration decreases, the flame current 11 increases.

時にバーナが不完全燃焼になりＣＯが発生し始める。(Depending on the design of the burner, it may fall.) At the same time, the burner becomes incompletely combusted and CO begins to be generated.
ここで炎電流目が相対値で７以上となった時にバーナを
停止し、ＣＯによる中毒事故等の危険を防ぐように働く
。Here, when the flame current reaches a relative value of 7 or more, the burner is stopped to prevent dangers such as accidents caused by CO poisoning.

内に累積されていくことも考えられる。Problems to be Solved by the Invention However, the above-mentioned conventional means are established on the prerequisites that the flame rod is not broken and that the flame current 11 changes reliably during abnormal combustion. In FIG. 4, even if the flame is burning normally in the frame rod 6, if parts other than rod 6 are abnormally burning and CO is generated, it cannot be detected. Also, in Fig. 5, the flame current Il is 5
If it is stagnant nearby, it is not abnormal combustion, but it is possible that CO is accumulating inside the room.
これ等最悪条件を考慮すると従来の方式のみでは万全と
いうことができないという問題点がある。Considering these worst-case conditions, there is a problem in that the conventional method alone cannot be completely reliable.

気率を入力する構成であっても良い。The control circuit section 22 operates the safety valve 1 in response to signals from the 7-ram rod 14 and other sensors for safe combustion in the burner 13.
At the same time, the signal from the room temperature sensor 23 is measured by the room temperature measurement unit 24, and the burner 1
3 combustion amount control is performed. Further, the room temperature signal from the room temperature measurement section 24 is used by the inclination detection section 25 to measure temperature changes (temperature rise or fall) per unit time. The ventilation timer section 26 is the burner 1
3 operates from the start of combustion and outputs a notification signal to the notification section 27 at regular intervals. Notification unit 27 outputs a notification to encourage ventilation by means of I-T device 28, an audio signal, or an /ri display (not shown). The operation time of the ventilation timer section 26 may be set in advance at a fixed time (for example, every hour), but it may also be configured such that the user inputs the size of the room or the ventilation rate using the condition setting section 29. .

を停止する。At the same time as the ventilation is output from the ventilation timer section 26, a signal is also input to the safety timer section 30 to start the safety timer. Safety timer section 30I/i This is for the purpose of determining whether or not ventilation has actually occurred within a certain period of time after the ventilation alarm is issued.If ventilation is not performed by the end of this safety timer 3°, the safety shutoff section 31 will operate. to close the safety valve 10 and stop combustion.

傾斜検知部２５の室温の傾斜で判定する。The safety shutoff unit 31 determines whether ventilation has been performed as instructed based on the slope of the room temperature detected by the slope detection unit 25.

報知のためのタイマカウントを開始する。Figure 2 shows this situation. In FIG. 2, the horizontal axis shows time and the vertical axis shows room temperature. The ventilation timer section 260 hours ends at the current time T1, and the safety timer 30 starts at the same time as the ventilation notification. If ventilation is not performed at this point, the room temperature will continue to rise, and combustion will stop at time T2 when the safety mark 30 ends. After the ventilation notification, at time T3, if the window is opened or the ventilation fan is operated to ventilate the room, the rise in room temperature decreases as shown by the broken line. Or the room temperature itself decreases. The inclination detection section 25 detects this change and determines that ventilation has been performed, and the ventilation timer section 26 starts a timer count for the next notification.

対応した機能部の番号を印す。FIG. 3 shows a simple flowchart when these operations are controlled by a microcomputer or the like. The numbers of the functional parts corresponding to those in Figure 1 are marked on the right side of the figure.
換気タイマ部２６の時間は、条件設定部２９により使用
者が任意に設定可能とすることにより暖房器を使用する
室内環境に応じて最適な時間間隔で換気報知可能となる
。By allowing the user to arbitrarily set the time of the ventilation timer section 26 by the condition setting section 29, ventilation notification can be performed at optimal time intervals according to the indoor environment in which the heater is used.
但しこの場合でも条件設定により決定される換気タイマ
時間の上限値は定めておく事がより安全となる。However, even in this case, it is safer to set an upper limit value for the ventilation timer time determined by the condition settings.
本発明はガスファンヒータ以外に石油７アンヒークにお
いても全く同じ効果を得るものであり、この場合は安全
弁１０に替えて燃料給油ポンプ等を駆動してもよい。In addition to the gas fan heater, the present invention can also achieve the same effect when using oil 7 unheated, and in this case, a fuel supply pump or the like may be driven instead of the safety valve 10.
