Automatic temperature control system based on feedback regulation

Abstract

The invention discloses an automatic temperature control system based on feedback regulation. The automatic temperature control system based on feedback regulation comprises a hot water inlet channel,a cold water inlet channel, a water outlet channel and a feedback control circuit, the hot water inlet channel controls flow through a second miniature electric ball valve and controls water pressurethrough a magnetic driving pump, the cold water inlet channel controls flow through a first miniature electric ball valve, cold water and hot water are sufficiently mixed in a water outlet channel mixing chamber and flow out of the system, and the temperature of the mixed water is subjected to feedback regulation by the control circuit. Compared with a traditional dormitory bath artifact, the automatic temperature control system has the advantages that the water pressure is increased by pumping, electric valves are added to control water quantity and prevent waste, the feedback control circuit is used for preventing scalding, proper temperature can be self-regulated, water temperature is kept constant by the aid of the mixing chamber, the water is prevented from being sometimes hot and sometimes cold, and use experience is improved.

Description

technical field [0001] The invention relates to a temperature control system, in particular to an automatic temperature control system based on feedback regulation. Background technique [0002] The temperature control system is a system that processes gases or liquids at different temperatures to reach the required temperature through a mechanical or electronic control system. It is widely used in life and industry, such as: temperature control of refrigerators, baking temperature control of baking machines ; Strict requirements for processing temperature in industrial thermal processing. [0003] Generally, temperature control systems are relatively expensive to manufacture, and are often used in high-end electrical appliances or high-cost industrial production activities. [0004] At present, most colleges and middle schools dormitories in our country do not have water heaters, and it is difficult to take a bath.

[0003] Generally, the temperature control system is relatively expensive to manufacture, and is often used in high-end electrical appliances or high-cost industrial production activities

[0004] At present, most colleges and middle schools dormitories in our country do not have water heaters, and it is difficult to take a bath. Among them, the bathing artifact using the siphon principle has been adopted on a large scale. Lead out, flow out after mixing in the pipeline, there are many problems as follows: (1) The use of siphon principle requires cold water flow velocity and water pressure to be sufficient to create a low-pressure environment, but most high-rise dormitories cannot achieve

(2) Unable to control flow, resulting in waste of water resources

(3) Insufficient mixing of hot and cold water in the pipeline, resulting in hot and cold phenomenon, poor user experience

(4) The temperature is uncontrollable, easy to burn or frostbite
