ところでこの従来のものでは、運転スイッチ16がON操作されてバーナ10の気化器12に設けられたヒータ(図示せず)に通電を開始して予熱し、気化器12の温度が点火可能な所定温度まで上昇したら、制御部19がシャッタモータ6に通電してシャッタ5の開放動作を行い、電磁ポンプを駆動して気化器12に燃料を供給すると共に燃焼用ファン11を駆動して気化器12に燃焼用空気を供給し、気化器12内で混合してガス化した予混合気を点火手段(図示せず)にて点火して運転を開始していたが、室温が低い場合、シャッタモータ6の起動特性が低下して、制御部19がシャッタモータ6に通電してもすぐにシャッタモータ6が動作せず、制御部19がシャッタモータ6に通電してから所定時間経過してもシャッタ5が所定位置まで開ききらず、制御部19がシャッタの動作エラーと判断して運転を停止することがあった。   By the way, in this prior art, the operation switch 16 is turned ON to start energization to a heater (not shown) provided in the vaporizer 12 of the burner 10 to preheat and the temperature of the vaporizer 12 can be ignited. When the temperature rises, the controller 19 energizes the shutter motor 6 to open the shutter 5, drives the electromagnetic pump to supply fuel to the carburetor 12, and drives the combustion fan 11 to drive the carburetor 12. Was started by igniting the premixed gas mixed and gasified in the carburetor 12 with ignition means (not shown), but when the room temperature is low, the shutter motor 6 is deteriorated, the shutter motor 6 does not operate immediately after the control unit 19 energizes the shutter motor 6, and the shutter does not stop even after a predetermined time has elapsed since the control unit 19 energized the shutter motor 6. 5 is the predetermined position Not completely open to the control unit 19 was able to stop the operation determines that the operation error of the shutter.

上記課題を解決するために、本発明の請求項1では、温風吹出口を有する本体と、気化させた燃料を燃焼するバーナと、該バーナの燃焼により発生した熱を温風吹出口から吹き出させる送風ファンと、前記温風吹出口を開閉するシャッタと、該シャッタを開閉するシャッタモータと、暖房運転を制御する制御部とを備えた温風暖房機に於いて、前記制御部は、運転開始時に室内が所定温度以下の時、点火動作が開始される前に事前にシャッタの開閉動作を行うものである。   In order to solve the above-mentioned problems, in claim 1 of the present invention, a main body having a hot air outlet, a burner that burns vaporized fuel, and air that blows out heat generated by the combustion of the burner from the hot air outlet. In a hot air heater comprising a fan, a shutter that opens and closes the hot air outlet, a shutter motor that opens and closes the shutter, and a control unit that controls heating operation, the control unit When the temperature is equal to or lower than a predetermined temperature, the shutter is opened and closed in advance before the ignition operation is started.

また、請求項2では、前記制御部は、運転開始時に室内が所定温度以下の時、その室内温度に応じて事前に行うシャッタの開閉動作の開閉動作回数を設定するものである。   According to a second aspect of the present invention, the controller sets the number of opening / closing operations of the shutter opening / closing operation to be performed in advance according to the room temperature when the room is at a predetermined temperature or lower at the start of operation.

また、請求項3では、前記制御部は、事前に行うシャッタの開閉動作の動作時間を計時し、その動作時間が所定時間を越えたシャッタの開閉動作回数を記憶し、その記憶した回数が所定回数以上になったらシャッタエラーと判断して運転を停止するものである。   According to a third aspect of the present invention, the control unit measures the operation time of the shutter opening / closing operation performed in advance, stores the number of times of opening / closing the shutter when the operation time exceeds a predetermined time, and the stored number of times is predetermined. If it exceeds the number of times, it is determined that there is a shutter error and the operation is stopped.

この発明の請求項1によれば、運転開始時に室内が所定温度以下の時、点火動作が開始される前に事前にシャッタの開閉動作を行うので、室温が低くてシャッタモータの起動特性が低下していても、点火動作が開始された時にスムーズにシャッタが閉塞状態から開放状態となり、低温によるシャッタモータの起動特性の低下が原因のシャッタエラーの発生を防止できるものである。   According to the first aspect of the present invention, when the room is at a predetermined temperature or less at the start of operation, the shutter opening / closing operation is performed in advance before the ignition operation is started. Even when the ignition operation is started, the shutter smoothly changes from the closed state to the open state, and the occurrence of a shutter error due to the deterioration of the starting characteristics of the shutter motor due to the low temperature can be prevented.

また、請求項2によれば、室温が低いほど事前シャッタ開閉数Nを多くするので、点火動作が開始されるまでに何回かシャッタが開閉され、それにより室温が低くとも点火動作が開始された時にスムーズにシャッタが閉塞状態から開放状態となり、低温によるシャッタモータの起動特性の低下が原因のシャッタエラーの発生を防止できるものである。   According to the second aspect of the invention, since the number N of preliminary shutter opening / closing increases as the room temperature is lower, the shutter is opened / closed several times before the ignition operation is started, so that the ignition operation is started even when the room temperature is low. Thus, the shutter smoothly changes from the closed state to the open state, and it is possible to prevent the occurrence of a shutter error due to the deterioration of the starting characteristics of the shutter motor due to the low temperature.

また、請求項3によれば、事前シャッタ開閉が所定時間以内に行われない状態が2回以上発生した時は点火動作が開始される前にシャッタエラーと判断して運転を停止するので、より安全性を高くすることが出来るものである。   According to the third aspect of the present invention, when the state in which the prior shutter opening / closing is not performed within a predetermined time occurs twice or more, the operation is stopped because it is determined as a shutter error before the ignition operation is started. Safety can be increased.

次に、本実施形態の作動について図4のフローチャート図に基づいて説明する。
尚、この1実施形態の温風暖房機は、符号1〜19の構成は前述の従来例と同様である。
まず、制御部19は、運転スイッチ16がON操作されたかを確認し(S1)、運転スイッチ16がON操作されたのを確認すると、次に室温検知手段が検知する室温が所定の温度、本実施例では−5℃以下かを確認し(S2)、−5℃より高ければ通常の点火動作に進み(S16)、−5℃以下であれば次に室温検知手段が検知する室温が所定の温度、本実施例では−15℃以下かを確認する。(S3)
Next, the operation of this embodiment will be described based on the flowchart of FIG.
In addition, the structure of the code | symbol 1-19 is the same as that of the above-mentioned prior art example in the warm air heater of this 1st Embodiment.
First, the control unit 19 confirms whether or not the operation switch 16 has been turned ON (S1), and if it is confirmed that the operation switch 16 has been turned ON, then the room temperature detected by the room temperature detection means is a predetermined temperature, In the embodiment, it is confirmed whether it is −5 ° C. or lower (S2). If it is higher than −5 ° C., the routine proceeds to a normal ignition operation (S16). It is confirmed whether the temperature is -15 ° C. or lower in this embodiment. (S3)

そして室温検知手段が検知する室温が−15℃より高ければ事前シャッタ開閉数Nを一回に設定し(S4)、−15℃以下であれば事前シャッタ開閉数Nを二回に設定する。(S5)   If the room temperature detected by the room temperature detecting means is higher than −15 ° C., the prior shutter opening / closing number N is set once (S4), and if it is −15 ° C. or lower, the prior shutter opening / closing number N is set twice. (S5)

そして運転スイッチ16がON操作されてから所定時間が経過したら(S6)、制御部19は事前シャッタ開閉動作を行い、シャッタモータ6に通電を行う。(S7)
その時、制御部19はシャッタモータ6に通電を行ってからシャッタ5が所定の位置まで開放されるまでの時間を計時してそれが所定時間内か否かを判断し(S8)、その時間が所定時間より長い時は開閉不良回数nに1を加算し(S9)、次にその開閉不良回数nが2回以上かを確認し(S10)、2回未満の時は(S7)に戻り、2回以上の時はシャッタエラーと判断して運転を停止して(S11)、シャッタエラー表示を行うものである。(S12)
When a predetermined time elapses after the operation switch 16 is turned on (S6), the control unit 19 performs a preliminary shutter opening / closing operation to energize the shutter motor 6. (S7)
At that time, the control unit 19 measures the time from when the shutter motor 6 is energized to when the shutter 5 is released to a predetermined position to determine whether or not it is within the predetermined time (S8). If it is longer than the predetermined time, 1 is added to the number of open / close failures n (S9), and then it is confirmed whether the number of open / close failures n is 2 or more (S10). If it is twice or more, it is determined that there is a shutter error and the operation is stopped (S11), and a shutter error display is performed. (S12)

また、(S8)でシャッタモータ6に通電を行ってからシャッタ5が所定の位置まで開放されるまでの時間が所定時間内の時は、次に気化器温度が点火温度にまで達したかを確認し(S13)、気化器温度が点火温度にまで達していない時は、シャッタ開閉数が設定した事前シャッタ開閉数Nに達したかを判断し(S14)、事前シャッタ開閉数Nに達していない時は(S7)に戻り、事前シャッタ開閉数Nに達している時は事前シャッタ開閉動作を終了して(S15)、通常の点火動作に進むものである。(S16)   Further, when the time from when the shutter motor 6 is energized in (S8) until the shutter 5 is released to a predetermined position is within a predetermined time, whether the carburetor temperature has reached the ignition temperature next. Confirmation (S13), when the vaporizer temperature does not reach the ignition temperature, it is determined whether the shutter opening / closing number has reached the preset number of previous shutter opening / closing N (S14), and the number of previous shutter opening / closing number N has been reached. If not, the process returns to (S7), and when the pre-shutter opening / closing number N has been reached, the pre-shutter opening / closing operation is terminated (S15) and the routine proceeds to a normal ignition operation. (S16)

このように、室温が所定の温度以下の時に運転スイッチ16がON操作された時、運転スイッチ16がON操作されてから点火動作が開始されるまでの間に、シャッタ開閉動作を事前に行うので、室温が低くてシャッタモータ6の起動特性が低下していても、点火動作が開始された時にスムーズにシャッタ5が閉塞状態から開放状態となり、低温によるシャッタモータ6の起動特性の低下が原因のシャッタエラーの発生を防止できるものである。   As described above, when the operation switch 16 is turned on when the room temperature is equal to or lower than the predetermined temperature, the shutter opening / closing operation is performed in advance from the time when the operation switch 16 is turned on until the ignition operation is started. Even when the room temperature is low and the start-up characteristic of the shutter motor 6 is reduced, the shutter 5 smoothly goes from the closed state to the open state when the ignition operation is started, and the start-up characteristic of the shutter motor 6 is lowered due to the low temperature. The occurrence of a shutter error can be prevented.

又、室温が低いほど事前シャッタ開閉数Nを多くするので、点火動作が開始されるまでに何回かシャッタ5が開閉され、それにより室温が低くとも点火動作が開始された時にスムーズにシャッタ5が閉塞状態から開放状態となり、低温によるシャッタモータ6の起動特性の低下が原因のシャッタエラーの発生を防止できるものである。   Further, since the number N of prior shutter opening / closing operations is increased as the room temperature is lower, the shutter 5 is opened / closed several times before the ignition operation is started, so that the shutter 5 is smoothly opened when the ignition operation is started even when the room temperature is low. The closed state is changed from the closed state to the opened state, and the occurrence of a shutter error due to a decrease in the starting characteristics of the shutter motor 6 due to a low temperature can be prevented.

又、事前シャッタ開閉が所定時間以内に行われない状態が2回以上発生した時は点火動作が開始される前にシャッタエラーと判断して運転を停止するので、より安全性を高くすることが出来るものである。   In addition, when a state where the prior shutter opening / closing is not performed within a predetermined time occurs twice or more, it is determined that a shutter error has occurred before the ignition operation is started, and the operation is stopped. It is possible.
