    • PURPOSE:To stabilize the control temperature and to increase the resetting speed of a temperature controller by using the output of a temperature comparison means to perform switching between the 1st and 2nd drive means and performing a heating process at all times through the 2nd drive means. CONSTITUTION:Heaters 22 and 23 of a heating means 21 are energized by an AC power supply 1 via relay switches 40-42, ane the temperature of a pan, etc. is controlled to a level set by a variable resistance 27. The switches 40-42 are controlled by relay coils 38 and 39 serving as the 1st and 2nd drive means respectively. This set temperature is compared with the temperature detected by a temperature detector 24 by a comparison means 29. These coils 38 and 39 are driven by a switching means 32. When the set temperature is lower than the detected temperature, the output of a comparator 30 is turned into a signal LO and the coil 39 is driven via a transistor TR37. Then heaters 22 and 23 are energized and heated. When the detected temperature reaches the set level, the output of the comparator 30 is inverted to turn off and on the TR37 and TR36 respectively. Then the coil 38 is driven to energize and heat the other heater 23.
    • 目的:通过使用温度比较装置的输出来稳定控制温度并提高温度控制器的复位速度,以在第一和第二驱动装置之间进行切换,并通过第二驱动装置一直执行加热过程。 构成:加热装置21的加热器22和23由交流电源1通过继电器开关40-42激励,锅的温度等被控制到由可变电阻27设定的电平。开关40 -42由分别用作第一和第二驱动装置的继电器线圈38和39控制。 该设定温度与由比较装置29由温度检测器24检测的温度进行比较。这些线圈38和39由开关装置32驱动。当设定温度低于检测到的温度时,比较器30的输出 变成信号LO,并且线圈39经由晶体管TR37驱动。 然后加热器22和23通电并加热。 当检测到的温度达到设定电平时,比较器30的输出反相分别关断和分别在TR37和TR36上。 然后驱动线圈38以激励和加热另一个加热器23。

    • PURPOSE:To extend the life of a relay contact with small-sized constitution, by connecting an impedance element between each diode and the connection part of a resistance in a heating body of a high temperature warming tool such as a hot carpet or the like and using the potential of the element as the output potential of a detecting circuit. CONSTITUTION:When an electrode switch 32 is closed, the leak current of a thermosensitive layer 4 is reduced and the voltage between both ends of a detecting resistance 14 is lower because the impedance of the thermosensitive layer 4 is large. The output of a comparing circuit 23 becomes ''H'' to turn on a driving transistor TR 28, and a relay group 29 is charged, and a contact 31 is closed to supply power to a heating body 1. When the heating body 1 reaches a set temperature, the impedance of the thermosensitive layer 4 becomes smaller, and the leak current is increased to increase the output potential between both ends of the detecting resistance 14, and this output becomes higher than a reference voltage, and the voltage between both ends of the resistance 14 is raised, and the output of the comparing circuit 23 becomes ''L''. Thus, a TR 26 is turned off, and the relay group 29 is discharged to open the contact 31, and the power supply to the heating body 1 is cut off.
    • 目的:为了延长具有小尺寸结构的继电器触点的寿命,通过在诸如热毯等的高温加热工具的加热体中的每个二极管和电阻的连接部分之间连接阻抗元件,以及 使用元件的电位作为检测电路的输出电位。 构成:当电极开关32闭合时,由于热敏层4的阻抗较大,热敏层4的漏电流减小,检测电阻14的两端之间的电压较低。 比较电路23的输出变为“H”以使驱动晶体管TR28导通,并且继电器组29被充电,并且触点31闭合以向加热体1供电。当加热体1 达到设定温度时,热敏层4的阻抗变小,漏电流增加,从而增大检测电阻14两端的输出电位,该输出变得高于参考电压,两者之间的电压 电阻14的端部升高,比较电路23的输出变为“L”。 因此,TR 26断开,并且继电器组29被排出以打开触点31,并且切断到加热体1的电力供应。

    • PURPOSE:To secure durability, by contriving an improvement in agreeable feeling and restricting a compressor so that the minimum value of OFF time of the compressor does not become lower than a predetermined value by setting up a variation range of a temperature of a blow-off air small. CONSTITUTION:When a temperature of blow-off air is lowered and a magnetic clutch 6 is turned OFF, the clutch 6 is apt to turn ON by raising the temperature of the blow-off air. During a time Tset, however, to be decided by resistor R11, a capacitor C1 and voltage at a point E the clutch 6 does not turn ON. As thermal load is large, this phenomenon occurs when a variation speed of the temperature of the blow-off air is large. Although the temperature of the blow- off air is turned into DELTATe' which is larger than DELTATe, durability of a compressor is secured. When the thermal load is small and the variation speed of the temperature of the blow-off air is small, the magnetic clutch is being turned OFF for more than a period of time corresponding to a predetermined temperature and a variation range of the temperature of the blow-off air can be controlled small at DELTATe.
    • 目的:为了确保耐久性,通过设定令人满意的感觉的改善和限制压缩机,使得压缩机的OFF时间的最小值不会变得低于预定值,通过设置吹出温度的变化范围 空气小 构成:当吹出空气的温度降低并且电磁离合器6断开时,通过提高吹出空气的温度,离合器6易于接通。 然而,在时间Tset期间,要由电阻器R11,电容器C1和点E处的电压决定离合器6不接通。 当热负荷大时,当吹出空气的温度的变化速度大时,会发生这种现象。 虽然吹出空气的温度变成大于DELTATe的DELTATe,但确保了压缩机的耐久性。 当热负荷小并且吹出空气的温度的变化速度小时,磁性离合器被关闭超过对应于预定温度的时间段和温度的变化范围 吹脱空气可以在DELTATe中控制得很小。

    • PURPOSE:To make maintenance and inspection unnecessary and to make a device compact and low-cost by supplying power to a large current conduction temperature switch, which is arranged in series between a heater and a power source and is stuck to the outside of a pipe, to heat the heater to a prescribed temperature. CONSTITUTION:When a switch is closed at a set timing, the current from a power source 5 is flowed to a heater coil 3 and a large current conduction temperature switch 12. Joule heat is generated in the coil 3 by this current to preheat a pipe 1, namely, an inside metallic sodium. Therefore, the temperature of the metallic sodium is raised to keep the liquid state, and it is flowed circularly in the pipe 1 and is used for a prescribed cooling action. When the metallic sodium is kept the liquid state to become a balanced state with respect to temperature, the switch 12 is broken in accordance with temperature-conduction control characteristics to cut off conduction of the current; and when the temperature falls, the switch 12 is made, and kind of start/stop control is performed to average the current with respect to time, and heating from the coil 3, namely, an incoming calorific value is constant.
    • 目的:为了不必要地进行维护和检查,并且通过向串联在加热器和电源之间的大电流传导温度开关供电并且被粘附到管道的外部而使设备紧凑并且成本低廉 ,将加热器加热到规定的温度。 构成:当在设定的时间关闭开关时,来自电源5的电流流到加热器线圈3和大电流传导温度开关12.通过该电流在线圈3中产生焦耳热,以预热管道 1,即内部金属钠。 因此,金属钠的温度升高以保持液体状态,并且在管1中循环流动并用于规定的冷却动作。 当金属钠保持液体状态成为相对于温度的平衡状态时,开关12根据温度传导控制特性而断开,以切断电流的传导; 并且当温度下降时,进行开关12,并且进行一些启动/停止控制以使电流相对于时间平均,并且从线圈3的加热,即进入的热值是恒定的。
