Problems solved by technology
After the water pressure entering the water heater is normal, the temperature of the total outlet water will change again. At this time, it must be adjusted again, which causes the user to often manually adjust the water temperature during use, which is troublesome.
At present, the constant temperature faucets on the market are complex in structure, the temperature measurement is not accurate enough, and the water heater with constant temperature function is even more expensive. If you want to enjoy the benefits of constant temperature, you must replace the existing traditional water heater, which is a waste of money.

Embodiment Construction
[0020] The present invention includes a hot water inlet, a cold water inlet, a total water outlet, and also includes a temperature sensor, a numerical control electric valve, a central processing unit, a memory, an operation panel and a feedback circuit. The numerical control electric valve, memory, operation panel and feedback circuit The circuits are respectively connected with the central processing unit, the central processing unit is also connected with the temperature sensor at the cold water inlet and the hot water inlet temperature sensor, and the total water outlet temperature sensor is connected with the feedback circuit.
[0021] There are four main types of temperature sensors: thermocouples, thermistors, resistance temperature detectors (RTDs), and IC temperature sensors. In this embodiment, an IC temperature sensor is used, which can digitally output the temperature of the measured object. In this embodiment, the temperature sensor is installed on the cold water i...

The invention relates to a water outlet device capable of automatically adjusting temperature, which comprises a hot water inlet, a cold water inlet and a general water outlet. The water outlet device is characterized by also comprising temperature sensors, a numerical control electric valve, a CPU, a memory, an operation panel and a feedback circuit, wherein the numerical control electric valve, the memory, the operation panel and the feedback circuit are connected with the CPU respectively; the CPU is also connected with the temperature sensor at the cold water inlet and the temperature sensor at the hot water inlet; and the temperature sensor at the general water outlet is connected with the feedback circuit. A user sets the temperature when using the water outlet device and the temperature of the water outlet is constant with the temperature set by the user no matter whether the temperatures of cold water and hot water is changed or not. When the temperature of water in a cold water pipe and a hot water pipe is changed, the water outlet device can quickly adjust the numerical control electric valve and has high water temperature adjustment speed and a small error between the adjusted water temperature and the set temperature. The technical scheme has the advantages of simple structure and low cost and can be applied to conventional water heaters.
Description
technical field [0001] The invention relates to a sanitary appliance, more specifically, to a water outlet device capable of automatically adjusting temperature. Background technique [0002] Although the temperature of the hot water coming out of the water heater is set by the user, the temperature of the water is not always stable, and the temperature of the hot water flowing out will change greatly with the change of the water pressure. When the user uses the water heater, the cold water is mixed with the hot water, and if the output hot water becomes hot or cold, the temperature of the total outlet water will change a lot, resulting in overheating or overcooling. The temperature of the total outlet water must then be adjusted manually. After the water pressure entering the water heater is normal, the temperature of the total outlet water will change again. At this time, it must be adjusted again, which causes the user to often manually adjust the water temperature durin...
