Instant heating type electric heating device

Abstract

The invention discloses an instant heating type electric heating device which comprises a liquid pipeline and a controlling unit, wherein the liquid pipeline is divided into a plurality of heating sections, an electrical bar is arranged in each heating section and used for providing heat to the liquid flowing over the heating section, so as to enable the liquid temperature to raise after absorbing the heat; and the controlling unit comprises a plurality of controlling parts, each controlling part is electrically connected with one electrical bar correspondingly and controls each electrical bar respectively, each controlling part is arranged and pasted on a section of the heat dissipating pipeline and services as the heat dissipating device of the controlling part, and the liquid pipeline is divided into a plurality sections of heating sector and matched with the electrical bars, so as to enable the liquid in the liquid pipeline to be in contact with a large area of heating resource to absorb heat, and achieve the purpose of rapid heating accordingly.

Description

technical field [0001] The invention relates to a liquid heating device, in particular to an instant electric heating device. Background technique [0002] Existing electric heating devices such as the patent case of Taiwan New Patent Announcement No. M371863 "Electric Water Heater with Disturbance Structure" have a heating element, a coil tube, and a heat pipe inside the heating body. The liquid inside the body is heated to raise the temperature. However, the body contains a large amount of liquid, so that the heating process takes more time and requires a lot of energy to heat the liquid to the set temperature. In addition to poor heat conversion efficiency , The heating time is long and the energy consumption is large. [0003] Another example is the patent case of Taiwan New Patent Announcement No. M404951 "Liquid Heater", which mainly includes a heating tube, a conductive component and a controller electrically connected to the conductive component. The curved tube bo...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned previous case M404951 solved the problems of poor thermal conversion efficiency and large energy consumption of the previous case M371863, the following problems still exist:

[0005] 1. The alloy electric heating layer is coated on the continuous curved pipe body, so when the alloy electric heating layer fails or is damaged, it is necessary to replace the entire set of continuous curved pipe bodies, which is quite inconvenient

[0006] 2. The alloy electric heating layer only has two modes of action: the whole group is activated or the whole group is not activated, so it is not easy to control the energy output, and there is also the possibility of wasting energy.

[0007] 3. Since the alloy electric heating layer is used to heat the liquid, it is not easy for the controller to control the power output, which affects the stability of the output liquid temperature, and the constant temperature effect is not good.

[0008] 4. The heat energy generated by the alloy electric heating layer needs to be transferred to the continuous curved tube first, and then to the liquid inside the tube, so that the heat conversion efficiency is poor and the heat energy is lost quickly
