The invention discloses a commercial gas cooker cooking energy saving device providing infrared monitoring signals, belonging to the technical field of single chip microcomputer application. It includes infrared induction device and valve control structure. The characteristics of SCM is the I / O is connected to the input end and the output end of the infrared transmitting and receiving device, and the output end of the gas valve switch control pulse motor to switch the execution structure is connected with MCU I / O, the switch actuator comprises two groups of switch tube, both ends of the output respectively with the pulse motor coil is connected. The invention creates a human body induction signal of a cooking utensil and an operator through a single chip microcomputer, and outputs the positive and negative pulses through a single chip microcomputer to change the direction and time of the power supply of the pulse motor. The beneficial effect is capable of automatically closing small gas in cooking when the hollowware leaves the kitchen range, when the return to the stove surface to restore gas supply, and has the function of time delay closing, to overcome the drawbacks of cooking when the switch is opened in the waste gas.
【技术实现步骤摘要】
本专利技术创造涉及一种商用燃气灶烹饪节能装置,特别涉及一种红外线提供监测信号的商用燃气灶烹饪节能装置,属于单片机技术应用领域。
技术介绍
本专利技术创造申请日前,商用燃气灶烹饪作业时燃气灶一直处于点燃状态,不论工作过程中锅子是否离开灶面,均无法自动控制,造成燃气的不间断浪费。
技术实现思路
本专利技术创造的目的是提供一种红外线提供监测信号的商用燃气灶烹饪节能装置。本专利技术创造解决其技术问题所采用的技术方案是包括红外线感应装置与阀门控制结构;单片机I/O的输入端与红外线发射与接收装置输出端相连接,单片机I/O的输出端与控制燃气阀门脉冲电机开闭的开关执行结构相连接。红外线发射与接收装置由红外发光管、红外接收管、脉冲方波电压发生器、运放器、解码器连接组成。脉冲电机的连接方式是单片机I/O的输出端与控制燃气阀门脉冲电机开闭的开关执行结构相连接,开关执行机构包括两组开关管,其输出分别与脉冲电机线圈的两端相连接。本专利技术创造的有益效果是在烹饪作业时当锅离开灶面时能自动关小燃气,当锅回到灶面时重新恢复供气,并具有延时关闭的功能,克服了烹饪作业时非关即开的浪费燃气的弊端。附图说明下面结合附图对本专利技术创造作进一步说明。图1为本专利技术创造的电原理图。具体实施例方式参阅图1。IC1输出的脉冲方波电压加在红外发光二极管VD2、VD3两端,驱动其向周围空间发射出调制红外光。由红外接收管VD4接收并转换为相应交变电压信号,经C4、R5耦合至运放IC2进行放大后,再经C5输入到解码器IC3的输入端,解码后并经过反相器VT2输出高电平,与单片机输入端I/O(1)相连接,单片机输 ...
