Abstract:
A water temperature detecting and controlling device having a cold and hot water mixing structure and a handle for controlling water flow comprised of:a water temperature sensing and controlling means; anda water flow regulating means;wherein said water flow regulating means is operated either automatically or manually to change the water temperature; when the manual control is used, the ratio of cold to hot water may be regulated directly by rotating said handle; when the electrical control is activated, the water temperature sensing and controlling means compares of the temperature set by a user to the detected temperature; if the temperatures are not the same, the water temperature sensing and controlling means will output a signal to drive the motor of said water flow regulating means to regulate the ratio of said cold to hot water, and the water temperature is changed until the set temperature is the same as that detected, then, the water temperature sensing and controlling means will stop the drive of the motor; andwherein said water temperature sensing and controlling means comprises:a detecting section;a central processing section;a display section;a control section; anda power source section;wherein when said handle is opened and water flows out, the power source section will enable the operation of all of the functions of all sections; by said detecting section, the central processing section will compare the detected temperature with the set temperature, if the two temperatures are different, the central processing section will drive the motor to rotate, regulating the respective flow of cold and hot water; if the two temperatures are the same, then the motor will be stopped, and the central processing section will display the temperature value on the display section.
