Description

本発明は、直流電源を使用する発熱体の温度を制御するための温度制御装置及び温度制御方法に関するものである。   The present invention relates to a temperature control device and a temperature control method for controlling the temperature of a heating element that uses a DC power supply.

一般に、ニクロムヒーターやハロゲンヒーター等の発熱体には、該発熱体の温度を設定温度に制御するために温度制御装置が設けられている。   In general, a heating element such as a nichrome heater or a halogen heater is provided with a temperature control device for controlling the temperature of the heating element to a set temperature.

従来のこの種の温度制御装置としては、例えば、発熱体の抵抗に対する電流と電圧のいずれか一方又はその両方の総量を制御するものや、或いは外部に設置した温度センサーの検出温度に基づきオン・オフ制御するものや、或いはリレースイッチを使用して単位時間当りのオン・オフの回数を調整するもの等が知られている（公知・公用の従来技術に基づき発明したため、出願人は本発明に関連する先行技術文献を知らない）。   Conventional temperature control devices of this type include, for example, devices that control the total amount of current and / or voltage with respect to the resistance of the heating element, or on / off based on the temperature detected by a temperature sensor installed outside. There are known ones that control off, or those that use relay switches to adjust the number of on / off times per unit time. I do not know the related prior art literature).

しかしながら、上記した従来の温度制御装置や温度制御方法は、図３に示すように、通電後、設定温度に達するのにある程度の時間（例えば、３秒程度）が掛かるニクロムヒーターやハロゲンヒーター等の一般の低効率の発熱体には適している。しかしながら、例えば、リレースイッチを使用して単位時間当りのオン・オフの回数を調整する方法の場合には、図４に示すように、オンの時間（ｔ１）とオフ（ｔ２）の時間が同じ時間になり、効率が５０％以上に上がることはない等の理由から、短時間（例えば、０．３秒程度）で設定温度に達するゲルマヒーター等の高効率の発熱体に、上記した従来の温度制御装置や温度制御方法を適用することができないといった問題があった。 However, the above-described conventional temperature control apparatus and temperature control method, as shown in FIG. 3, includes a nichrome heater, a halogen heater, or the like that takes a certain amount of time (for example, about 3 seconds) to reach a set temperature after energization. Suitable for general low-efficiency heating elements. However, for example, in the case of adjusting the number of on / off times per unit time using a relay switch, as shown in FIG. 4, the on time (t 1 ) and the off time (t 2 ) Because of the same time and efficiency does not increase to more than 50%, high efficiency heating elements such as germane heaters that reach the set temperature in a short time (for example, about 0.3 seconds) There has been a problem that conventional temperature control devices and temperature control methods cannot be applied.

また、交流電源を使用する機器による電磁波の発生問題に対応するため、近年、直流電源の機器を使用するケースもあるが、上記した従来の温度制御装置及び温度制御方法では、発熱体の電源として交流電源を使用するため、磁場振動が発生し、人体への被害が懸念されるといった安全上の問題もあった。   In addition, in order to cope with the problem of electromagnetic wave generation due to equipment using an AC power supply, there are cases where equipment using a DC power supply is used in recent years. However, in the above-described conventional temperature control device and temperature control method, Since an AC power supply is used, there was a safety problem that magnetic field vibrations occurred and there were concerns about damage to the human body.

本発明は、上記した課題を解決すべくなされたものであり、高効率の発熱体にも適用できると共に、磁場振動の発生による人体への被害を防止することのできる温度制御装置及び温度制御方法を提供することを目的とするものである。   The present invention has been made to solve the above-described problem, and can be applied to a high-efficiency heating element and can prevent damage to the human body due to the occurrence of magnetic field vibration. Is intended to provide.

上記した目的を達成するため、本発明は、直流電源を使用する発熱体の温度を制御するための温度制御装置であって、特定の周波数において前記発熱体のオンの時間とオフの時間の長さが異なるように変化させて該発熱体の温度を制御することを特徴とする。   In order to achieve the above-described object, the present invention is a temperature control device for controlling the temperature of a heating element using a DC power source, wherein the heating element is turned on and off at a specific frequency. The temperature of the heating element is controlled by changing the temperature of the heating element so as to be different.

また、本発明は、直流電源を使用する発熱体の温度を制御するための温度制御方法であって、特定の周波数において前記発熱体のオンの時間とオフの時間の長さが異なるように変化させて該発熱体の温度を制御することを特徴とする。   The present invention is also a temperature control method for controlling the temperature of a heating element that uses a DC power supply, and the heating element is turned on and off differently at a specific frequency. And controlling the temperature of the heating element.

本発明によれば、特定の周波数において発熱体のオンの時間とオフの時間の長さが異なるように変化させて該発熱体の温度を制御することにより、高効率の発熱体にも適用可能となると共に、磁場振動の発生による人体への被害を防止することができる。   According to the present invention, the heating element can be applied to a high-efficiency heating element by controlling the temperature of the heating element by changing the length of the on-time and the off-time of the heating element to be different at a specific frequency. In addition, damage to the human body due to the occurrence of magnetic field vibration can be prevented.

以下、図面を参照しつつ、本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図２（ａ），（ｂ），（ｃ），（ｄ）に示すように、この温度制御装置１２は、特定の周波数（例えば、５０Ｈｚ又は６０Ｈｚ）において発熱体１１のオンの時間（ｔ１）とオフの時間（ｔ２）の長さが異なるように変化させて発熱体１１の温度を制御する。 As shown in FIGS. 2 (a), (b), (c), and (d), the temperature control device 12 is configured to turn on the heating element 11 at a specific frequency (for example, 50 Hz or 60 Hz) (t 1 ) And the off time (t 2 ) are changed so as to be different from each other to control the temperature of the heating element 11.

このように、オン・オフの時間比率（ｔ１／ｔ２）、すなわち、オン・オフの面積比率を変化させることにより細かな温度制御を行うことができるようになると共に、効率を高めることができる。 Thus, by changing the on / off time ratio (t 1 / t 2 ), that is, the on / off area ratio, fine temperature control can be performed, and efficiency can be improved. it can.

また、発熱体１１を一般家庭で使用する５０Ｈや６０Ｈｚ程度の安全な周波数の直流電源で使用することにより、磁場振動の発生による人体への被害を確実に防止することができる。   In addition, by using the heating element 11 with a DC power source having a safe frequency of about 50H or 60 Hz used in a general home, damage to the human body due to the occurrence of magnetic field vibration can be reliably prevented.
