【従来の技術】[Prior Art]

従来の電気カーペット等の電気暖房器の温度制御装置は、図4に示すように電 熱ヒーター2の温度制御は、温度検知線3からの信号を温度検知回路14により 直流電圧化し、温度設定手段7によって設定されたリレー12のON電圧及びリ レー12のOFF電圧とをコンパレータ16にて比較してそのコンパレーター1 6の出力をトランジスタ13を介してリレー12のON/OFF制御を行い、本 体1の温度を一定温度幅に制御する事によって設定温度を保つ構成であった。( 例えば実開昭62−102911号公報参照) In a conventional temperature controller for an electric heater such as an electric carpet, the temperature of the electric heater 2 is controlled as shown in FIG.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上記構成によると温度設定手段7による設定温度と、本体1を 設置している床の材質と、本体1の周囲温度等により本体1からの放熱量がさま ざまになるため電熱ヒーター2を通電制御するリレー12のON時間とOFF時 間が条件により異なるため図5に示すように放熱量が多いときは1サイクルの時 間が短くなり、放熱量が少ない場合は1サイクルの時間が長くなり、ON/OF Fの1サイクルの時間がさまざまとなっている。 However, according to the above configuration, the amount of heat radiated from the main body 1 varies depending on the temperature set by the temperature setting means 7, the material of the floor on which the main body 1 is installed, the ambient temperature of the main body 1, etc. Since the ON time and OFF time of the relay 12 for controlling energization vary depending on the conditions, as shown in Fig. 5, the time of one cycle becomes short when the heat radiation amount is large, and the time of one cycle becomes long when the heat radiation amount is small. Therefore, the time of one cycle of ON / OF F varies.

【0004】 このため1サイクルの時間が短すぎるとリレー12の開閉回数が多くなってし まいリレー12の寿命が短くなる。For this reason, if the time of one cycle is too short, the number of times the relay 12 is opened and closed increases and the life of the relay 12 becomes short.

【0005】 また,1サイクルの時間が長い場合には、電熱ヒーター2の通電間隔が長くな ってしまうので,電気カーペット等の電気暖房器を使用する採暖者が電熱ヒータ ー2のON/OFFの波を感じてしまい採暖感が悪いと云う問題点を有していた 。Further, when the time of one cycle is long, the energization interval of the electric heater 2 becomes long, so a warmer using an electric heater such as an electric carpet turns ON / OFF the electric heater 2. There was a problem that the feeling of heat collection was bad due to the feeling of the wave of.

That was temperature control circuit having a function.

【作用】[Action]

マイクロコンピューターは、まず通電初期は設定温度と本体温度の温度差によ りリレーのON/OFFのデューティーをプログラムにあらかじめ設定して有る 値によって電熱ヒーターの通電を制御する。 At the beginning of energization, the microcomputer first controls the energization of the electric heater according to the preset value of the ON / OFF duty of the relay depending on the temperature difference between the set temperature and the main body temperature.

【実施例】【Example】

本考案の構成を示す一実施例の添付図面図1〜図3に基づいて説明する。 An embodiment of the present invention will be described with reference to the accompanying drawings FIGS.

【0011】 図1及び図2において、本体1内に電熱ヒーター2と本体1の温度を検知する 温度検知線3とを配設しており、前記本体1の温度を設定する温度設定手段7を 設けたコントローラーボックス4を本体1に設けてある。In FIGS. 1 and 2, an electric heater 2 and a temperature detection wire 3 for detecting the temperature of the main body 1 are arranged in the main body 1, and a temperature setting means 7 for setting the temperature of the main body 1 is provided. The controller box 4 provided is provided on the main body 1.

【0012】 コントローラーボックス4内に,電源Sに接続した電源回路6と,その電源回 路6に接続したCPU11とROM10とメモリ8およびタイマ9からなるマイ クロコンピュータ15と、そのマイクロコンピュータ15に接続した温度設定手 段7および前記温度検知線3に接続され本体1の温度を検知する温度検知回路1 4と,マイクロコンピュータ15の出力側に接続されたトランジスタ13と,そ のトランジスタ13の一端に接続した電熱ヒーター2の温度制御を行なうリレー 12とを設けてある。なお,CPU11とROM10とメモリ8およびタイマ9 からなるマイクロコンピュータ15とマイクロコンピュータ15の出力側に接続 されたトランジスタ13とで温度制御回路5を構成している。In the controller box 4, a power supply circuit 6 connected to the power supply S, a CPU 11 connected to the power supply circuit 6, a microcomputer 10 including a ROM 10, a memory 8 and a timer 9 and a microcomputer 15 connected to the microcomputer 15. The temperature setting circuit 7 and the temperature detection circuit 14 connected to the temperature detection line 3 for detecting the temperature of the main body 1, the transistor 13 connected to the output side of the microcomputer 15, and one end of the transistor 13. A relay 12 for controlling the temperature of the connected electric heater 2 is provided. The temperature control circuit 5 is composed of a microcomputer 15 including a CPU 11, a ROM 10, a memory 8 and a timer 9 and a transistor 13 connected to the output side of the microcomputer 15.

【0013】 次に,上記構成における作用を説明する。Next, the operation of the above configuration will be described.

【0014】 前記温度設定手段7の信号と温度検知回路14の信号をCPU11とROM1 0とメモリ8およびタイマ9からなるマイクロコンピュータ15に取り込み、マ イクロコンピュータ15はROM10に記憶した演算処理を行い,マイクロコン ピュータ15からの出力信号によりトランジスタ13を介してリレー12のON /OFF通電により電熱ヒーター2の通電制御を行い本体1の温度を一定に保つ 。The signal of the temperature setting means 7 and the signal of the temperature detection circuit 14 are taken into a microcomputer 15 composed of a CPU 11, a ROM 10, a memory 8 and a timer 9, and the microcomputer 15 performs arithmetic processing stored in the ROM 10, The temperature of the main body 1 is kept constant by controlling the energization of the electric heater 2 by turning on / off the relay 12 via the transistor 13 by the output signal from the micro computer 15.

【0015】 本考案の特性を示す図3において,まず電源Sを投入し本体1の温度が設定温 度まで上昇する間は、リレー12をONのままにして電熱ヒーター2に通電され る。本体1の温度が設定温度を越えた時に電熱ヒーター2の通電をOFFする。 そして,一定時間後に再び電熱ヒーター2の通電を一定時間ONする。このと き電熱ヒーター2のOFFしている時間t1と電熱ヒーター2のONしている時 間t2の合計時間t3はたとえば3分間一定とする。そしてこのON/OFFサイ クルの平均温度と設定温度の差によって次のサイクルの電熱ヒーター2のON/ OFFのデューティーを補正し、本体1の全体が暖まってくると電熱ヒーター2 の通電ON時間t2を短くし、一方電熱ヒーター2の通電OFF時間t1を長くし 、1サイクルの通電時間t3が3分(一定)となるように電熱ヒーター2のON 時間t2、電熱ヒーター2の通電OFF時間t1を決定して通電を行う。In FIG. 3 showing the characteristics of the present invention, first, while the power source S is turned on and the temperature of the main body 1 rises to the set temperature, the relay 12 is kept ON and the electric heater 2 is energized. When the temperature of the main body 1 exceeds the set temperature, the electric heater 2 is turned off. Then, after a certain period of time, the electric heater 2 is turned on again for a certain period of time. At this time, the total time t3 of the time t1 when the electric heater 2 is off and the time t2 when the electric heater 2 is on is set to be constant for 3 minutes, for example. Then, the ON / OFF duty of the electric heater 2 in the next cycle is corrected by the difference between the average temperature of the ON / OFF cycle and the set temperature, and when the whole body 1 is warmed up, the ON time t2 of the electric heater 2 is turned on. On the other hand, the energization OFF time t1 of the electric heater 2 is lengthened, and the ON time t2 of the electric heater 2 and the energization OFF time t1 of the electric heater 2 are set so that the energization time t3 of one cycle is 3 minutes (constant). Determine and energize.

【0016】 さらに,たとえば周囲温度が低くて本体1からの放熱量が多い場合は、電熱ヒ ーター2の通電のON時間t2が長く、OFF時間t1を短く通電し設定温度を保 つ。また周囲温度が高い場合などの本体1からの発熱量が少ない場合には、電熱 ヒーター2通電のON時間t2を短く、OFF時間t1を長くし設定温度を保つ。 このように動作するため、本体1を設定温度に保ちつつ、本体1の発熱量の如 何に係わらずリレー12のON/OFF動作は必ず3分に一定となる。Further, for example, when the ambient temperature is low and the amount of heat radiated from the main body 1 is large, the ON time t2 for energization of the electric heating heater 2 is long and the OFF time t1 is short for energization to maintain the set temperature. When the amount of heat generated from the main body 1 is small, such as when the ambient temperature is high, the ON time t2 for energizing the electric heater 2 is shortened and the OFF time t1 is lengthened to maintain the set temperature. Since the operation is performed in this manner, the ON / OFF operation of the relay 12 is always kept constant for 3 minutes regardless of the heat generation amount of the main body 1 while keeping the main body 1 at the set temperature.

【0017】 また,電熱ヒーター2のONの間隔が一定となる。Further, the ON interval of the electric heater 2 becomes constant.

【考案の効果】[Effect of the device]

以上述べたように,本考案は次の効果が得られる。 As described above, the present invention has the following effects.

【0019】 温度設定手段による設定温度と、本体を設置している床の材質と、本体の周囲 温度等により本体からの放熱量がさまざまになつても電熱ヒーターを通電制御す るリレーのON時間とOFF時間との合計時間が条件により放熱量が多いときあ るいは放熱量が少ない場合でも1サイクルの時間が一定となり、ON/OFFの 1サイクルの時間がさまざまとならない。The ON time of the relay that controls the energization of the electric heater even if the amount of heat radiated from the main body varies depending on the temperature set by the temperature setting means, the material of the floor on which the main body is installed, the ambient temperature of the main body, etc. Depending on the conditions, the total time of ON and OFF times is constant even if the heat radiation amount is large or the heat radiation amount is small, and the ON / OFF 1 cycle time does not vary.

【0020】 また,リレーのON/OFF回数が時間に対して一定となるため使用条件の如 何に係わらず、リレーの寿命時間を一定時間必ず確保できるので,リレーの寿命 が長くなる。Further, since the number of times the relay is turned ON / OFF is constant with respect to time, the life of the relay can be ensured for a certain period of time regardless of the operating conditions, so the life of the relay is extended.

【0021】 なお,電熱ヒーターの通電ONの間隔が長くなることがないため電熱ヒーター のON/OFFの波を感ずることがなく,採暖感が良くなつた。It should be noted that since the interval of turning on the electricity of the electric heater did not become long, there was no sense of the ON / OFF wave of the electric heater, and the warming feeling was improved.
