Liquid heating equipment with power display

Abstract

The invention discloses liquid heating equipment with power display. A heating body is included, and after being connected with a power adjusting circuit, a sampling resistor and a protection circuitin series, the heating body is connected with commercial power. The two ends of the sampling resistor are connected with an amplifying circuit through a wire, and the other end of the amplifying circuit is electrically connected with a single-chip microcomputer through a wire. The liquid heating equipment has the beneficial effects that the liquid heating equipment with power display can measure the output power of the electric heating body in real time, a user can conveniently and accurately adjust the output power of the electric heating body according to needs, in other words, the water temperature is accurately regulated and controlled, it is ensured that the water temperature cannot fluctuate up down, subsequent hot water usage is facilitated, and practicability is good.

Description

technical field [0001] The invention relates to the field of liquid heating equipment, in particular to a liquid heating equipment with power display. Background technique [0002] An electric water heater is an electric heating device that is often used in daily life. It relies on the heating body installed in the water tank to heat cold water. The heating body in the prior art generally does not have a power display, so users cannot accurately adjust the electric heating The output power of the heater can only be regulated according to experience, so it is impossible to precisely control the water temperature during the process of water insulation, because different output power corresponds to heating different water temperatures, once the heater enters the heat preservation state for a period of time, The water temperature will fluctuate up and down and cannot be kept at a certain value, which undoubtedly brings a lot of inconvenience to the subsequent use of hot water. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a liquid heating device with power display in order to solve the above problems, so as to solve the problem that the output power of the electric heating body in the liquid heating device in the prior art cannot be measured, and correspondingly it is impossible to accurately adjust the electric heating element. The output power of the heating body makes it impossible to precisely control the water temperature, and the water temperature tends to fluctuate up and down, which affects the subsequent use of hot water and other issues
