防冷动装置制造方法及图纸

本实用新型专利技术属于温度控制器所附加的、防止必须在热状态下工作的机床或设备冷启动的装置。它采用了可控硅记忆电路和节能的继电器启动维持电路，体积小，成本低，电路简单可靠。可以保证受温度控制的机床、设备在设定温度未达到时不能启动，又能保证在设定温度达到时立即启动，从而可以避免机床或设备因冷启动而受损，也可以避免因加热时间过长迟迟不启动而造成能量及工时的浪费。（*该技术在1997年保护过期，可自由使用*）

Anti freezing device

The utility model belongs to a device for preventing cold starting of a machine tool or a device attached to a temperature controller to work in a hot state. It adopts silicon controlled memory circuit and energy-saving relay to start maintenance circuit. It is small in size, low in cost and simple and reliable in circuit. Can guarantee the temperature control of the machine and equipment can not be started at the set temperature does not reach, and can guarantee the start immediately in the set temperature is reached, so as to avoid the machine or equipment damaged by cold start, it can avoid the energy and time due to the delay in starting the heating time is too long to waste.
