Problems solved by technology

When taking a bath, hot water is generally needed, especially in winter, the water heater needs to be turned on for a period of time to produce hot water, which inadvertently wastes the cold water
Moreover, the temperature adjustment of the manual valve of the water heater is very unstable, and the water temperature is easy to be too hot or too cold, and the water temperature is also very unstable.

Embodiment Construction

[0016] Such as figure 2 Shown is the schematic diagram of the whole system, from which we can simply see the function to be realized:

[0017] When running the water heater, the single-chip microcomputer outputs a PWM wave with a certain duty ratio to drive the steering gear to make the water-saving pipeline of the three-way ball valve conduct and perform water-saving treatment; The steering gear makes the water outlet of the three-way ball valve open, and hot water comes out. When it detects that the water temperature is higher than the set temperature value, the single-chip microcomputer outputs PWM wave to reduce the size of the hot water inlet valve; when it detects that the water temperature is lower than the set temperature value, the single-chip microcomputer outputs PWM wave to increase the size of the hot water inlet valve Size to regulate water temperature constant.

[0018] Such as figure 1 As shown, the device of the present invention based on the intelligent w...

Abstract

The invention discloses a device and method based on intelligent water temperature control of a water heater and water conservation design of an outer pipeline. By selecting a conducting channel of a three-way spherical valve, cold water in the pipeline is stored to be reused. A man-machine channel is designed to replace a mechanical valve and the temperature of the output water is simpler and more accurate to be adjusted through a fuzzy control method. Because a man-machine keyboard is utilized, the trouble of frequent adjusting is avoided compared with the mechanical valve and the problem of burning caused by excessively adjusting a hot water valve is also solved.

Description

technical field [0001] The invention relates to the technical fields of PWM control, temperature detection and control, man-machine channel technology, fuzzy control, pipeline structure design, etc., and particularly relates to a device and method based on intelligent water temperature control of a water heater and water-saving design of an outer pipeline. Background technique [0002] Water is an essential condition for the survival of all living things on earth. Without water, there would be no such beautiful world of ours. Although the earth is rich in water resources, most of them exist in the sea and glaciers, and the water resources that can be used by us are less than 0.02%. With the development of industrial technology, a large amount of pollution has penetrated into rivers and lakes, and the water resources we can use are further reduced. Many places have no water to drink. Saving water from daily life has become a hot topic. [0003] As a household appliance, the...
