Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, illustrate only the part relevant to the utility model in accompanying drawing but not full content.
Please refer to shown in Fig. 1, the controllable temperature immersion heater circuit structure diagram that Fig. 1 provides for the utility model embodiment.
In the present embodiment, controllable temperature immersion heater circuit specifically comprises: temperature setting button group 101, LCD MODULE 102, temperature sensor 103, controller 104, power control circuit 105, heating tube 106 and voice guard 107.Described button group, LCD MODULE 102, temperature sensor 103, power control circuit 105, voice guard 107 are electrically connected with controller 104.Described heating tube 106 is electrically connected with power control circuit 105.As shown in Figure 2, described power control circuit 105 comprises photoelectrical coupler U1, resistance R1, bidirectional triode thyristor B1, resistance R2.Wherein, first input end connection control device 104, second input of described photoelectrical coupler U1 connects external power supply, one end of the first output contact resistance R1, one end of the second output contact resistance R2, the control pole of bidirectional triode thyristor B1; The other end of resistance R1 connects the second plate of bidirectional triode thyristor B1, and the contact after the other end of resistance R2 is connected with the first anode of bidirectional triode thyristor B1 connects heating tube 106.In Fig. 2,220V is communication power supply, and computer heating control is that controller 104 output exports controlled quentity controlled variable, adds to export to heat for controlling heating tube 106.
In the present embodiment, described temperature setting button group 101 comprises three buttons: water temperature of making tea button, drinks water temperature button, water temperature of washing one's face and rinsing one's mouth button.The water temperature range that water temperature of making tea button is preset is 70 degree to 80 degree, and the water temperature range of drinking water temperature button default is 30 degree to 40 degree, and the temperature range that water temperature of washing one's face and rinsing one's mouth button is preset is 45 degree to 65 degree.The water temperature information that described LCD MODULE 102 is fed back for real-time displays temperature transducer 103.1-wire digital temperature sensor 103 selected by described temperature sensor 103.1-wire digital temperature sensor 103 directly can export digital quantity, and the interface of single wire device and controller 104 only needs a holding wire, and hardware circuit is very simple, easily realizes.Stm32 single-chip microcomputer selected by described controller 104, stm32 includes the ADC of 2 12,3 general 16 bit timing devices and 1 PWM timer, also comprise standard and advanced communication interface: nearly 2 I2C interfaces and SPI interface, 3 USART interfaces, a USB interface and CAN interfaces, are enough to meet the demands.Described heating tube 106 is U-shape.The built-in loudspeaker of described voice guard 107, have warning function, and storage has several acoustic information.
