Abstract

PROBLEM TO BE SOLVED: To provide a heater that performs temperature control according to a deviation of a detected temperature of room temperature detecting means from a predetermined set temperature, and that operates on receiving an ON command when a detected temperature of second room temperature detecting means falls to a first reference temperature or lower and stops operating on receiving an OFF command when the detected temperature of the second room temperature detecting means rises above a second reference temperature set higher than the first reference temperature, and puts the second reference temperature closer to a room temperature when a user makes change to raise the second reference temperature of a thermostat.SOLUTION: Heating UP control is performed to raise a set temperature by a predetermined value or to increase heating value by a predetermined value when an OFF command is not received within a first predetermined time after an ON command is received from a thermostat 8, or a state in which a detected temperature of room temperature detecting means 6 of a heater 1 is equal to or higher than the set temperature lasts for a second predetermined time without reception of the OFF command.

Description

本発明は、室温検出手段と、室温検出手段の検出温度と所定の設定温度との偏差に応じて室内空気の加熱量を調整する温調制御を行う制御手段とを備える暖房機に関する。   The present invention relates to a heater including room temperature detection means and control means for performing temperature control that adjusts the amount of heating of room air in accordance with a deviation between a temperature detected by the room temperature detection means and a predetermined set temperature.

従来、この種の暖房機として、特許文献１により、制御手段を、既に他の器具とも接続されているサーモスタットに接続するものが知られている。サーモスタットは、暖房機の室温検出手段とは独立した別の第２の室温検出手段を有し、第２の室温検出手段の検出温度が所定の第１基準温度以下になったときにオン指令を出力し、第２の室温検出手段の検出温度が第１基準温度よりも高く設定される所定の第２基準温度以上になったときにオフ指令を出力する。制御手段は、サーモスタットからのオン指令を受けて暖房機を運転する制御を行うと共に、サーモスタットからのオフ指令を受けて暖房機を停止する制御を行う。そして、特許文献１に記載のものでは、サーモスタットからのオフ指令を受けたときの暖房機の室温検出手段の検出温度と設定温度との偏差に応じて、再びオン指令を受けたときに行う温調制御の設定温度を更新するようにしている。   Conventionally, as this type of heater, Patent Document 1 discloses that a control unit is connected to a thermostat that is already connected to other appliances. The thermostat has another second room temperature detection means independent of the room temperature detection means of the heater, and issues an ON command when the detected temperature of the second room temperature detection means falls below a predetermined first reference temperature. When the detected temperature of the second room temperature detecting means becomes equal to or higher than a predetermined second reference temperature set higher than the first reference temperature, an off command is output. The control means performs control for operating the heater in response to an ON command from the thermostat, and performs control to stop the heater in response to an OFF command from the thermostat. And in the thing of patent document 1, the temperature performed when an ON command is received again according to the deviation of the detection temperature of the room temperature detection means of a heater when it receives the OFF command from a thermostat, and setting temperature. The set temperature of adjustment control is updated.

尚、暖房機の制御手段は、サーモスタットからのオン指令とオフ指令を受けるだけで、サーモスタットで設定される第１基準温度や第２基準温度は認識できない。そこで、サーモスタットからのオフ指令を受けたときに室温が例えば第２基準温度に上昇していても、その室温とは無関係な既に設定された設定温度で温調制御が行われてしまうことを防止するため、上記従来例のものでは、上記の如く設定温度を更新するようにしている。   Note that the control means of the heater only receives an on command and an off command from the thermostat, and cannot recognize the first reference temperature and the second reference temperature set by the thermostat. Therefore, even when the room temperature rises to, for example, the second reference temperature when an off command is received from the thermostat, temperature control is prevented from being performed at a preset temperature that is unrelated to the room temperature. For this reason, in the conventional example, the set temperature is updated as described above.

ところで、暖房機の運転中に、使用者がサーモスタットの第２基準温度を上げるように変更すると、暖房機の設定温度は第２基準温度より低温となるが、上記従来例のものでは、暖房機側でサーモスタットの第２基準温度を認識できず、暖房機の運転中に設定温度は変更されない。この場合、サーモスタットからのオン指令を受けてから長時間経過しても、室温は第２基準温度に上昇し難く、サーモスタットからのオフ指令を受けない状態が継続する。また、暖房機の室温検出手段の検出温度が設定温度に到達すると、暖房機の制御手段は加熱量を減少して温調制御を行い、室温検出手段の検出温度が設定温度以上である状態が長時間継続しても、室温は第２基準温度に上昇し難く、サーモスタットからのオフ指令を受けない。即ち、使用者がサーモスタットの第２基準温度を上げて室内を暖かくしようとしても、その第２基準温度に室温が上昇しない状態が継続する。   By the way, if the user changes the temperature so that the second reference temperature of the thermostat is raised during operation of the heater, the set temperature of the heater becomes lower than the second reference temperature. The second reference temperature of the thermostat cannot be recognized on the side, and the set temperature is not changed during operation of the heater. In this case, even if a long time elapses after receiving the ON command from the thermostat, the room temperature hardly rises to the second reference temperature, and the state where the OFF command from the thermostat is not received continues. When the detected temperature of the room temperature detecting means of the heater reaches the set temperature, the control means of the heater performs temperature control by reducing the heating amount, and there is a state where the detected temperature of the room temperature detecting means is equal to or higher than the set temperature. Even if it continues for a long time, the room temperature hardly rises to the second reference temperature and does not receive an off command from the thermostat. That is, even if the user tries to warm the room by raising the second reference temperature of the thermostat, the state where the room temperature does not rise to the second reference temperature continues.

本発明は、以上の点に鑑み、使用者がサーモスタットの第２基準温度を上げるように変更したときに、その第２基準温度に室温を近づけることができるようにした暖房機を提供することをその課題としている。   In view of the above, the present invention provides a heater that can bring the room temperature closer to the second reference temperature when the user changes the second reference temperature of the thermostat. That is the issue.

上記課題を解決するために、本発明は、室温検出手段と、室温検出手段の検出温度と所定の設定温度との偏差に応じて室内空気の加熱量を調整する温調制御を行う制御手段とを備える暖房機であって、暖房機の室温検出手段とは別の第２の室温検出手段を有し、第２の室温検出手段の検出温度が所定の第１基準温度以下になったときにオン指令を出力し、第２の室温検出手段の検出温度が第１基準温度よりも高く設定される所定の第２基準温度以上になったときにオフ指令を出力するサーモスタットが制御手段に接続され、制御手段は、サーモスタットからのオン指令を受けて暖房機を運転する制御を行うと共に、サーモスタットからのオフ指令を受けて暖房機を停止する制御を行うものにおいて、サーモスタットからのオン指令を受けてから第１の所定時間経過するまでにオフ指令を受けないとき又は暖房機の室温検出手段の検出温度が設定温度以上である状態がオフ指令を受けないまま第２の所定時間継続したとき、設定温度を所定値上げるか又は加熱量を所定値増加する暖房アップ制御を行うことを特徴とする。   In order to solve the above problems, the present invention includes a room temperature detection unit, and a control unit that performs temperature control that adjusts the amount of heating of the room air in accordance with a deviation between a temperature detected by the room temperature detection unit and a predetermined set temperature. A second room temperature detecting means different from the room temperature detecting means of the heater, and when the detected temperature of the second room temperature detecting means becomes equal to or lower than a predetermined first reference temperature. A thermostat that outputs an ON command and outputs an OFF command when the temperature detected by the second room temperature detection means becomes equal to or higher than a predetermined second reference temperature that is set higher than the first reference temperature is connected to the control means. The control means receives the on command from the thermostat and controls the heater to be operated, and receives the off command from the thermostat and performs the control to stop the heater, and receives the on command from the thermostat. Or When no OFF command is received before the first predetermined time elapses, or when the temperature detected by the room temperature detecting means of the heater is equal to or higher than the set temperature, the set temperature is maintained for the second predetermined time without receiving the OFF command. Heating up control is performed to increase the heating amount by a predetermined value or increase the heating amount by a predetermined value.

本発明によれば、使用者がサーモスタットの第２基準温度を上げるように変更することで、サーモスタットからのオン指令を受けてから第１の所定時間経過するまでにオフ指令を受けない又は暖房機の室温検出手段の検出温度が設定温度以上である状態がオフ指令を受けないまま第２の所定時間継続すると、設定温度を所定値上げるか又は加熱量を所定値増加する暖房アップ制御が行われて、室温を上昇させることができる。従って、使用者がサーモスタットの第２基準温度を上げるように変更したときに、その第２基準温度に室温を近づけることができる。   According to the present invention, when the user changes the thermostat to increase the second reference temperature, the user does not receive the off command until the first predetermined time elapses after receiving the on command from the thermostat or the heater. When the temperature detected by the room temperature detecting means is equal to or higher than the set temperature, when the second predetermined time is continued without receiving the OFF command, the heating up control is performed to increase the set temperature by a predetermined value or increase the heating amount by a predetermined value. Thus, the room temperature can be raised. Therefore, when the user changes the second reference temperature of the thermostat to increase, the room temperature can be brought closer to the second reference temperature.

また、本発明においては、暖房アップ制御を行ってから第３の所定時間経過するまでにオフ指令を受けないとき、再び暖房アップ制御を行うことが望ましい。これによれば、段階的に設定温度を上げて又は段階的に加熱量を増加して、第２基準温度に室温を上昇させることができる。   In the present invention, it is desirable to perform the heating up control again when no off command is received after the third predetermined time elapses after the heating up control. According to this, it is possible to raise the room temperature to the second reference temperature by raising the set temperature stepwise or increasing the heating amount stepwise.

図１を参照して、１は本実施形態の暖房機の機体を示している。機体１内には、バーナ２１を内蔵する燃焼筐２と、バーナ２１の燃焼ガスが内部に流れる熱交換器３とが配置されている。バーナ２１に対する燃料ガスの供給路２２には、供給路２２の開閉を行う電磁弁２２ａと、燃料ガスの流量を可変する比例弁２２ｂとが介設されている。そして、燃焼筐２の上流の給気通路２３から空気を供給し、熱交換器３の下流端の排気ファン３１を介して燃焼ガスを排気通路３２に排出している。また、熱交換器３の上方に設けられた対流ファン４の作動により、機体１の背面に開設された吸気口５１から吸い込まれる室内空気を熱交換器３との熱交換で加熱し、温風として機体１の前面下部に開設された吹出口５２から機外に吹き出させるようにしている。   With reference to FIG. 1, 1 has shown the body of the heater of this embodiment. In the body 1, a combustion housing 2 containing a burner 21 and a heat exchanger 3 through which combustion gas of the burner 21 flows are arranged. The fuel gas supply path 22 for the burner 21 is provided with an electromagnetic valve 22a for opening and closing the supply path 22 and a proportional valve 22b for changing the flow rate of the fuel gas. Then, air is supplied from the air supply passage 23 upstream of the combustion housing 2, and the combustion gas is discharged to the exhaust passage 32 via the exhaust fan 31 at the downstream end of the heat exchanger 3. Further, by the operation of the convection fan 4 provided above the heat exchanger 3, the indoor air sucked from the intake port 51 opened on the back surface of the machine body 1 is heated by heat exchange with the heat exchanger 3, As a result, the air is blown out from the air outlet 52 opened at the lower front of the airframe 1.

また、暖房機１は、吸気口５１から吸い込まれる室内空気の温度を検出する室温検出手段６と、室温検出手段６の検出温度と所定の設定温度との偏差に応じて、比例弁２２ｂを制御して室内空気の加熱量を調整する温調制御を行う制御手段たるコントローラ７とを備えている。コントローラ７には、暖房機１の室温検出手段６とは別の第２の室温検出手段８１を有し、第２の室温検出手段８１の検出温度が所定の第１基準温度以下になったときにオン指令を出力し、第２の室温検出手段８１の検出温度が第１基準温度よりも高く設定される所定の第２基準温度以上になったときにオフ指令を出力するサーモスタット８が接続されている。コントローラ７は、サーモスタット８からのオン指令を受けて、電磁弁２２ａを開弁すると共に排気ファン３１及び対流ファン４を作動して暖房機１を運転する制御を行うと共に、サーモスタット８からのオフ指令を受けて、電磁弁２２ａを閉弁すると共に排気ファン３１及び対流ファン４の作動を停止して暖房機１を停止する制御を行う。また、サーモスタット８は、第１基準温度及び第２基準温度を変更できるように構成されている。   Also, the heater 1 controls the proportional valve 22b according to the deviation between the temperature detected by the room temperature detecting means 6 and a predetermined set temperature, and the room temperature detecting means 6 for detecting the temperature of the indoor air sucked from the intake port 51. And a controller 7 serving as a control means for performing temperature control for adjusting the heating amount of the room air. The controller 7 has a second room temperature detection means 81 different from the room temperature detection means 6 of the heater 1, and when the detected temperature of the second room temperature detection means 81 becomes a predetermined first reference temperature or lower. Is connected to a thermostat 8 that outputs an ON command and outputs an OFF command when the temperature detected by the second room temperature detecting means 81 becomes equal to or higher than a predetermined second reference temperature set higher than the first reference temperature. ing. The controller 7 receives the ON command from the thermostat 8, opens the electromagnetic valve 22 a, operates the exhaust fan 31 and the convection fan 4 to operate the heater 1, and controls the OFF command from the thermostat 8. In response to this, the solenoid valve 22a is closed and the operation of the exhaust fan 31 and the convection fan 4 is stopped to stop the heater 1. Further, the thermostat 8 is configured so that the first reference temperature and the second reference temperature can be changed.

ここで、暖房機１の運転中に、使用者がサーモスタット８の第２基準温度を上げるように変更して、暖房機１の設定温度が第２基準温度より低温となった場合、暖房機１側でサーモスタット８の第２基準温度を認識できず、サーモスタット８からのオン指令を受けてから長時間経過しても、室温は第２基準温度に上昇し難く、サーモスタット８からのオフ指令を受けない状態が継続する。また、暖房機１の室温検出手段６の検出温度が設定温度に到達すると、暖房機１のコントローラ７は加熱量を減少して温調制御を行い、室温検出手段６の検出温度が設定温度以上である状態が長時間継続しても、室温は第２基準温度に上昇し難く、サーモスタット８からのオフ指令を受けない。即ち、使用者がサーモスタット８の第２基準温度を上げて室内を暖かくしようとしても、その第２基準温度に室温が上昇しない状態が継続する。   Here, when the user changes the temperature so that the second reference temperature of the thermostat 8 is raised during the operation of the heater 1, and the set temperature of the heater 1 becomes lower than the second reference temperature, the heater 1 The second reference temperature of the thermostat 8 cannot be recognized on the side, and the room temperature hardly rises to the second reference temperature even if a long time has passed after receiving the on command from the thermostat 8, and the off command from the thermostat 8 is received. No state continues. When the detected temperature of the room temperature detecting means 6 of the heater 1 reaches the set temperature, the controller 7 of the heater 1 performs the temperature control by reducing the heating amount, and the detected temperature of the room temperature detecting means 6 is equal to or higher than the set temperature. Even if this state continues for a long time, the room temperature hardly rises to the second reference temperature and does not receive an off command from the thermostat 8. That is, even if the user increases the second reference temperature of the thermostat 8 and tries to warm the room, the state where the room temperature does not increase to the second reference temperature continues.

そこで、本実施形態では、コントローラ７は、サーモスタット８からのオン指令を受けてから第１の所定時間経過するまでにオフ指令を受けないとき又は暖房機１の室温検出手段６の検出温度が設定温度以上である状態がオフ指令を受けないまま第２の所定時間継続したとき、設定温度を所定値上げるか又は加熱量を所定値増加する暖房アップ制御を行う。更に、暖房アップ制御を行ってから第３の所定時間経過するまでにオフ指令を受けないとき、再び暖房アップ制御を行う。尚、コントローラ７は、サーモスタット８からのオフ指令を受けたときの暖房機１の室温検出手段６の検出温度と設定温度との偏差に応じて、再びオン指令を受けたときに行う温調制御の設定温度を更新する。以下、図２を参照して、暖房機１で行う制御について詳述する。   Therefore, in the present embodiment, the controller 7 sets the temperature detected by the room temperature detecting means 6 of the heater 1 when it does not receive the off command until the first predetermined time elapses after receiving the on command from the thermostat 8. When the temperature or higher is continued for the second predetermined time without receiving the OFF command, the heating up control is performed to increase the set temperature by a predetermined value or increase the heating amount by a predetermined value. Furthermore, when no OFF command is received from the time when the heating-up control is performed until the third predetermined time elapses, the heating-up control is performed again. The controller 7 controls the temperature when the ON command is received again according to the deviation between the detected temperature of the room temperature detecting means 6 of the heater 1 and the set temperature when the OFF command is received from the thermostat 8. Update the set temperature. Hereinafter, the control performed by the heater 1 will be described in detail with reference to FIG.

先ず、使用者が例えば暖房機１の主電源を入れると、ＳＴＥＰ１で、コントローラ７がサーモスタット８からのオン指令を受けた否か、即ち、サーモスタット８の第２の室温検出手段８１の検出温度が所定の第１基準温度以下となったか否かを判別する。コントローラ７がサーモスタット８からのオン指令を受けると、ＳＴＥＰ２で、暖房機１の運転を開始し、室温検出手段６の検出温度Ｔｒと所定の設定温度Ｔｓとの偏差に応じて室内空気の加熱量を調整する温調制御を行う。このように、コントローラ７がサーモスタット８からのオン指令を受けて、暖房機１の運転を開始すると、ＳＴＥＰ３で、コントローラ７が具備するタイマーＡの計時動作を開始（タイマーＡ開始）する。   First, when the user turns on the main power supply of the heater 1, for example, in STEP 1, whether or not the controller 7 has received an ON command from the thermostat 8, that is, the detected temperature of the second room temperature detecting means 81 of the thermostat 8 is It is determined whether or not the temperature is equal to or lower than a predetermined first reference temperature. When the controller 7 receives an ON command from the thermostat 8, in STEP 2, the operation of the heater 1 is started, and the amount of heating of the room air according to the deviation between the detected temperature Tr of the room temperature detecting means 6 and the predetermined set temperature Ts. Performs temperature control to adjust. As described above, when the controller 7 receives the ON command from the thermostat 8 and starts the operation of the heater 1, in STEP 3, the timer A provided in the controller 7 starts the time measuring operation (timer A start).

次に、ＳＴＥＰ４で、タイマーＡ開始から第１の所定時間（例えば２０分）経過したか否かを判別すると共に、暖房機１の室温検出手段６の検出温度Ｔｒが設定温度Ｔｓ以上となり、その状態が第２の所定時間（例えば１０分）継続したか否かを判別する。第１の所定時間経過するまで又はＴｒ≧Ｔｓである状態が第２の所定時間継続するまでは、ＳＴＥＰ５で、コントローラ７がサーモスタット８からのオフ指令を受けた否か、即ち、サーモスタット８の第２の室温検出手段８１の検出温度が所定の第２の基準温度以上となったか否かを判別し、コントローラ７がサーモスタット８からのオフ指令を受けると、ＳＴＥＰ６で、暖房機１を停止する。そして、ＳＴＥＰ７で、サーモスタット８からのオフ指令を受けたときの暖房機１の室温検出手段６の検出温度Ｔｒと設定温度Ｔｓとの偏差に応じて、再びオン指令を受けたときに行う温調制御の設定温度Ｔｓを更新して、ＳＴＥＰ１に戻る。尚、設定温度Ｔｓの更新は、例えば、前の設定温度Ｔｓに検出温度Ｔｒと設定温度Ｔｓの偏差の２分の１を加算することで行うが、前の設定温度Ｔｓに検出温度Ｔｒと設定温度Ｔｓの偏差を加算することで行うこと、即ち、設定温度Ｔｓをサーモスタット８からのオフ指令を受けたときの室温検出手段６の検出温度Ｔｒに更新することも可能である。   Next, in STEP 4, it is determined whether or not a first predetermined time (for example, 20 minutes) has elapsed since the start of the timer A, and the detected temperature Tr of the room temperature detecting means 6 of the heater 1 becomes equal to or higher than the set temperature Ts. It is determined whether or not the state has continued for a second predetermined time (for example, 10 minutes). Until the first predetermined time elapses or until the state where Tr ≧ Ts continues for the second predetermined time, in STEP 5, whether or not the controller 7 has received an OFF command from the thermostat 8, that is, the thermostat 8 When it is determined whether the detected temperature of the second room temperature detecting means 81 is equal to or higher than a predetermined second reference temperature and the controller 7 receives an OFF command from the thermostat 8, the heater 1 is stopped in STEP6. Then, in STEP 7, the temperature adjustment performed when the ON command is received again according to the deviation between the detected temperature Tr of the room temperature detecting means 6 of the heater 1 and the set temperature Ts when the OFF command is received from the thermostat 8. The control set temperature Ts is updated, and the process returns to STEP1. The set temperature Ts is updated by, for example, adding one half of the deviation between the detected temperature Tr and the set temperature Ts to the previous set temperature Ts. However, the set temperature Ts is set to the previous set temperature Ts. It is also possible to add the deviation of the temperature Ts, that is, to update the set temperature Ts to the detected temperature Tr of the room temperature detecting means 6 when receiving an off command from the thermostat 8.

一方、ＳＴＥＰ４で、第１の所定時間経過した又はＴｒ≧Ｔｓである状態が第２の所定時間継続したと判断すると、ＳＴＥＰ８で、設定温度Ｔｓを所定値ΔＴ（例えば１℃）上げる暖房アップ制御を行う。これによれば、使用者がサーモスタット８の第２基準温度を上げるように変更することで、サーモスタット８からのオン指令を受けてから第１の所定時間経過するまでにオフ指令を受けない又はＴｒ≧Ｔｓである状態がオフ指令を受けないまま第２の所定時間継続すると、設定温度Ｔｓを所定値ΔＴ上げる暖房アップ制御が行われて、室温を上昇させることができる。従って、使用者がサーモスタット８の第２基準温度を上げるように変更したときに、その第２基準温度に室温を近づけることができる。また、図示しないが、暖房アップ制御は、設定温度Ｔｓを所定値ΔＴ上げることに代えて、比例弁２２ｂの開度を大きくして、室内空気の加熱量を所定値増加してもよい。これによれば、上記同様に、第２基準温度に室温を近づけることができる。   On the other hand, when it is determined in STEP 4 that the first predetermined time has elapsed or the state of Tr ≧ Ts has continued for the second predetermined time, in STEP 8, the heating-up control for increasing the set temperature Ts by a predetermined value ΔT (for example, 1 ° C.). I do. According to this, when the user changes the temperature so that the second reference temperature of the thermostat 8 is raised, the user does not receive the off command until the first predetermined time elapses after receiving the on command from the thermostat 8 or Tr When the state of ≧ Ts continues for the second predetermined time without receiving the off command, the heating up control for increasing the set temperature Ts by the predetermined value ΔT is performed, and the room temperature can be raised. Therefore, when the user changes the thermostat 8 to increase the second reference temperature, the room temperature can be brought close to the second reference temperature. Although not shown, the heating-up control may increase the heating amount of the room air by a predetermined value by increasing the opening degree of the proportional valve 22b instead of increasing the set temperature Ts by the predetermined value ΔT. According to this, similarly to the above, the room temperature can be brought close to the second reference temperature.

そして、ＳＴＥＰ８で、設定温度Ｔｓを所定値ΔＴ上げるか又は加熱量を所定値増加する暖房アップ制御を行うと、ＳＴＥＰ９で、コントローラ７が具備するタイマーＢの計時動作を開始（タイマーＢ開始）する。その後、ＳＴＥＰ１０で、コントローラ７がサーモスタット８からのオフ指令を受けた否かを判別し、ＳＴＥＰ１１で、タイマーＢ開始から第３の所定時間（例えば２０分）経過したか否かを判別する。第３の所定時間経過までにコントローラ７がサーモスタット８からのオフ指令を受けると、ＳＴＥＰ６に進み、タイマーＢ開始から第３の所定時間経過するまでにコントローラ７がオフ指令を受けないと、ＳＴＥＰ８に戻る。これによれば、段階的に設定温度Ｔｓを上げて又は段階的に加熱量を増加して、第２基準温度に室温を上昇させることができる。   Then, in STEP8, when heating up control is performed in which the set temperature Ts is increased by a predetermined value ΔT or the heating amount is increased by a predetermined value, the timer B provided in the controller 7 starts the timekeeping operation in STEP9 (timer B start). . Thereafter, in STEP 10, it is determined whether or not the controller 7 has received an OFF command from the thermostat 8. In STEP 11, it is determined whether or not a third predetermined time (for example, 20 minutes) has elapsed since the start of the timer B. If the controller 7 receives an off command from the thermostat 8 until the third predetermined time elapses, the process proceeds to STEP 6, and if the controller 7 does not receive an off command before the third predetermined time elapses from the start of the timer B, the process proceeds to STEP 8. Return. According to this, it is possible to raise the room temperature to the second reference temperature by raising the set temperature Ts stepwise or increasing the heating amount stepwise.
