本发明属于生活用品领域，涉及一种带智能沐浴头，尤其是涉及一种带智能沐浴头的节水热水器，能够进行闭环精确控制水温和在不增加机械结构基础上最大限度节水。The invention belongs to the field of daily necessities, and relates to an intelligent shower head, in particular to a water-saving water heater with an intelligent shower head, capable of closed-loop precise control of water temperature and maximum water saving without increasing the mechanical structure.
背景技术Background technique
目前很多地方，例如家庭，宾馆和学校浴室，都用到了热水器这个装置。热水器存在两个比较大的问题，第一，在打开热水器的热水开关的时候，刚刚出来的是冷水，而且有时候冷水会流很久，才出来了热水。特别是冬天洗澡的时候，需要在旁边等水变热，会感觉到很不舒服，同时大量的干净的冷水被浪费。第二，在冬天洗澡的时候，有时候水温会降下来，或者是调节到比较舒适的水温需要很长的时间。这两点给许多的用户带来很多的不便。为了节约水资源，同时有更好的用户体验，需要一种新型的智能热水器。At present, many places, such as families, hotels and school bathrooms, have used the water heater device. There are two relatively big problems with the water heater. First, when the hot water switch of the water heater is turned on, cold water just comes out, and sometimes the cold water will flow for a long time before hot water comes out. Especially when taking a bath in winter, you need to wait for the water to heat up, which makes you feel very uncomfortable, and a large amount of clean cold water is wasted. Second, when taking a bath in winter, sometimes the water temperature will drop, or it will take a long time to adjust to a more comfortable water temperature. These two points bring a lot of inconvenience to many users. In order to save water resources and have a better user experience, a new type of smart water heater is needed.
虽然现在有很多智能热水器（包括带有回流装置的）在技术上不断的完善，但是他们设计的装置比较复杂，大多数采用机械结构来控制，存在成本高，装置复杂，操作部方便，高功耗等问题。Although there are many smart water heaters (including those with reflux devices) that are constantly improving technically, the devices they design are relatively complicated, and most of them are controlled by mechanical structures. Consumption and other issues.

本发明的具体实施工作过程如下：Concrete implementation work process of the present invention is as follows:
当用户设定好所需的温度的时候，按下出水/停水按键11，此时MSP430F5438单片机发出控制信号，通过线路通道7，将信号传给混水阀门驱动电路，控制电机，从而带动混水电控阀门5的旋转，将混水阀门打开。流出来的水经过温度传感器14，温度传感器14对水温进行检测，温度传感器14处理后将数字量送给单片机控制电路13，输出结果与设定的温度相对比。When the user has set the required temperature, press the water outlet/stop water button 11, at this time the MSP430F5438 MCU sends a control signal, which is transmitted to the mixing valve drive circuit through the line channel 7 to control the motor, thereby driving the mixing valve. The rotation of the water electric control valve 5 opens the water mixing valve. The water flowing out passes through the temperature sensor 14, and the temperature sensor 14 detects the water temperature. After the temperature sensor 14 processes, the digital quantity is sent to the single-chip microcomputer control circuit 13, and the output result is compared with the set temperature.
当实际水温比设定的温度高的时候，MSP430单片机发出控制命令，通过线路通道7，传给混水阀门驱动电路5，控制电机，从而带动阀门的旋转，来加大冷水的进水量，反之，MSP430单片机发出控制信号，通过线路通道7，传给混水阀门驱动电路5，控制电机，从而带动阀门的旋转，加大热水进水量。单片机里可采用控制理论里面的PID方法，可在不需要具体了解混水电控阀门与出水温度定量关系的前提下，实时监测水温的变化，当水温降低时，加大热水阀门，水温偏高时候，加大冷水阀门，对水温进行精确控制，而且响应快速，能够很快的收敛到设定温度。When the actual water temperature is higher than the set temperature, the MSP430 microcontroller sends a control command, which is transmitted to the mixing valve drive circuit 5 through the line channel 7 to control the motor, thereby driving the rotation of the valve to increase the intake of cold water, and vice versa , MSP430 single-chip microcomputer sends a control signal, which is transmitted to the mixing valve drive circuit 5 through the line channel 7 to control the motor, thereby driving the rotation of the valve and increasing the water intake of hot water. The PID method in the control theory can be used in the single-chip microcomputer, and the change of the water temperature can be monitored in real time without knowing the quantitative relationship between the electric control valve of the mixed water and the outlet water temperature. When it is high, increase the cold water valve to precisely control the water temperature, and the response is fast, and it can quickly converge to the set temperature.
在用户使用热水的过程中，温度传感器14不断的对水温进行检测，将检测结果送回MSP430单片机控制电路13，实时进行与设定温度比较，来控制混水电控阀门5。在用户需要调节水量大小的时候，按下智能沐浴头上面的水量调节按键12，按键信号传给MSP430单片机控制电路13，然后单片机进行处理，将处理后的信号经过线路通道7传给进水阀门驱动电路，从而控制电机对进水阀门15的大小进行调节。When the user uses hot water, the temperature sensor 14 continuously detects the water temperature, and sends the detection result back to the MSP430 single-chip microcomputer control circuit 13, and compares it with the set temperature in real time to control the electric control valve 5 for mixing water. When the user needs to adjust the water volume, press the water volume adjustment button 12 on the smart shower head, the button signal is sent to the MSP430 single-chip microcomputer control circuit 13, and then the single-chip microcomputer processes it, and sends the processed signal to the water inlet valve through the line channel 7 Drive the circuit, thereby controlling the motor to adjust the size of the water inlet valve 15.
当用户设定好自己想要的温度的时候，并且按下出水/停水按键时候，此时MSP430单片机发出控制命令，通过电路信号线，将信号传给混水阀门驱动电路，将混水电控阀门打开，温度传感器采集水温，将实际的水温的模拟信号输入MSP430单片机，MSP430单片机自带AD转换功能，将模拟温度信号转化为数字信号，用于单片机的处理，将其与设定的温度相比较，当实际水温低于设定温度的时候，单片机发出控制命令，驱动混水电控阀门的驱动电路，驱动电路控制混水电控阀门，加大热水的流量。When the user sets the desired temperature and presses the water outlet/stop water button, the MSP430 MCU sends a control command, and the signal is sent to the mixed water valve drive circuit through the circuit signal line, and the mixed water power The control valve is opened, the temperature sensor collects the water temperature, and the analog signal of the actual water temperature is input into the MSP430 single-chip microcomputer. The MSP430 single-chip microcomputer has its own AD conversion function, which converts the analog temperature signal into a digital signal for the processing of the single-chip microcomputer, and compares it with the set temperature. In comparison, when the actual water temperature is lower than the set temperature, the single-chip microcomputer sends a control command to drive the drive circuit of the water mixing electric control valve, and the drive circuit controls the water mixing electric control valve to increase the flow of hot water.
