Water flow constant temperature heating method and water flow constant temperature heating device specially for intelligent toilet

Abstract

The invention relates to a water flow constant temperature heating method and device specially for an intelligent toilet. The steps are as follows: 1) Measure the water flow through the water flow sensor, and convert the square wave signal of the measured water flow into a variable resistance signal through the water flow / resistance converter, and the heating drive system controls the heating according to the measured water flow signal The power output of the drive system; 2) The water flows through the power tube radiator of the heating drive system to cool and dissipate the power tube radiator of the heating drive system, and the water flow brings the heat emitted by the power tube into the heater; 3) The water flow It is heated by the electromagnetic induction heater, and the heated water flows through the digital temperature sensor for data collection and transmission to the main control system. The main control system controls the heating drive system according to the temperature data collected by the digital temperature sensor and the set water temperature. The driving power keeps the water temperature constant at the set temperature; the water flow sensor and the digital temperature sensor work together to control the water temperature in two stages.

Description

technical field [0001] The invention relates to the field of frequency conversion electromagnetic induction heating, more specifically, a water flow constant temperature heating method and a water flow constant temperature heating device specially for intelligent toilets. Background technique [0002] The existing smart toilet with constant temperature water outlet equipment basically uses electric heating tubes to heat the water flow and then supply it for use. The heat storage type heating equipment must always maintain the water temperature of the water storage tank, which consumes a lot of power. During the process, the electric heating tube is always soaked in the water, and the current continuously or intermittently induces the heating of the electric heating tube, so as to achieve a constant temperature state of water storage and energy storage in the water tank. Its flaws are: [0003] A. High water quality requirements can easily lead to scale condensation on heati...
