其中控制器连接端口1的引脚排列顺序为MCU引脚、GND引脚、RLY引脚、NTC引脚、KG引脚、BUZ引脚、VDD引脚。The order of the pin arrangement of the controller connection port 1 is MCU pin, GND pin, RLY pin, NTC pin, KG pin, BUZ pin, VDD pin.
与压力锅安装时，控制器连接端口1与压力锅中的控制器连接、压力开关连接端口3与压力锅中的压力开关连接、温度传感器连接端口4与压力锅中的温度传感器连接。When installing with a pressure cooker, the controller connection port 1 is connected to the controller in the pressure cooker, the pressure switch connection port 3 is connected to the pressure switch in the pressure cooker, and the temperature sensor connection port 4 is connected to the temperature sensor in the pressure cooker.
工作时，控制器通过控制器连接端口1控制继电器电路2中的继电器开关闭合，使发热盘得电发热，同时压力开关连接端口3不断检测压力开关的状态，发热盘发热使压力锅内部水汽蒸发，使得压力锅内部大气压增大，当压力锅内部大气压达到一定值时，压力锅的压力开关被触发，压力开关连接端口3检测到压力开关被触发的信号传输到控制器连接端口1中，控制器接收到压力开关被触发信号，通过控制器连接端口1控制继电器电路2中的继电器控制开关断开，使压力锅停止加热。When working, the controller controls the relay switch in the relay circuit 2 to close through the controller connection port 1, so that the heating plate is energized and heated, and at the same time, the pressure switch connection port 3 continuously detects the state of the pressure switch, and the heat of the heating plate evaporates the water vapor inside the pressure cooker. The internal atmospheric pressure of the pressure cooker increases. When the internal atmospheric pressure of the pressure cooker reaches a certain value, the pressure switch of the pressure cooker is triggered, and the pressure switch connection port 3 detects that the pressure switch is triggered. The signal is transmitted to the controller connection port 1, and the controller receives the pressure The switch is triggered by a signal, and the relay control switch in the relay circuit 2 is controlled to be disconnected through the controller connection port 1, so that the pressure cooker stops heating.
另一方面，继电器RLY1的电源是由开关电源电路6顺次通过压力开关连接端口1引脚①、压力开关、压力开关连接端口1引脚③、继电器RLY1输入端形成给继电器RLY1提供工作电压的供电回路，当压力开关被触发断开时，供电回路断路，继电器RLY1失电，继电器控制开关断开，压力锅停止加热。On the other hand, the power supply of the relay RLY1 is formed by the switching power supply circuit 6 sequentially through the pressure switch connection port 1 pin ①, the pressure switch, the pressure switch connection port 1 pin ③, and the input terminal of the relay RLY1 to provide the working voltage for the relay RLY1 The power supply circuit, when the pressure switch is triggered and disconnected, the power supply circuit is disconnected, the relay RLY1 loses power, the relay control switch is disconnected, and the pressure cooker stops heating.
本实用新型压力开关断开时，既通过控制器向继电器电路2输出控制信号，控制继电器RLY1停止工作，同时也通过压力开关断开继电器RLY1的供电电源，使继电器RLY1断开停止工作，因此，即使压力锅中的控制器出现错误不能控制继电器电路2断开继电器开关时，断开继电器RLY1的电源输入也能使压力锅停止加热工作，大大提高了使用压力锅的安全性。When the pressure switch of the utility model is disconnected, the controller outputs a control signal to the relay circuit 2 to control the relay RLY1 to stop working, and at the same time disconnects the power supply of the relay RLY1 through the pressure switch, so that the relay RLY1 is disconnected and stops working. Therefore, Even if the controller in the pressure cooker has an error and cannot control the relay circuit 2 to disconnect the relay switch, disconnecting the power input of the relay RLY1 can also stop the heating of the pressure cooker, which greatly improves the safety of using the pressure cooker.
当烹饪的食物含水量低时，通过温度传感器来控制器压力锅的烹饪过程；当烹调食物完成时，控制器通过控制器连接端口1控制蜂鸣器电路5工作，提示食物烹调完成。When the water content of the cooked food is low, the temperature sensor is used to control the cooking process of the pressure cooker; when the cooking of the food is completed, the controller controls the buzzer circuit 5 to work through the controller connection port 1, prompting that the cooking of the food is completed.
当本实用新型与电饭煲安装时，在所述压力开关连接端口3的引脚①与其引脚③之间设置跳线J2，电饭煲控制器只需与控制器连接端口1中的MCU引脚、GND引脚、RLY引脚连接，通过跳线J2将继电器RLY1线圈的一个输入端和开关电源电路6连接。When the utility model is installed with the rice cooker, a jumper J2 is set between the pin ① of the pressure switch connection port 3 and its pin ③, and the rice cooker controller only needs to be connected with the MCU pin, GND in the controller connection port 1. Pin and RLY pin are connected, and one input terminal of the relay RLY1 coil is connected with the switching power supply circuit 6 through the jumper J2.
