Heating device and method of electric water heater

Abstract

A household electric hot water supplier capable of rapid hot water supply at stable water temperature and power saving, comprised two parts. Where to the top of the upper surplus heating part links the water inlet tube and to the bottom of the lower priority heating part links the water outlet tube. The lower part (vaporizing part) of a heat transmitter is located in the priority heating part while the upper part (condensing part) is located in the surplus heating part. An electric heater is installed to the bottom of the vaporizing part. A self-convection prohibiting board is installed in the water box. When the temperature of the priority part reaches a certain level, the heat transmitter will transmit the heat to the surplus heating part. Vis-a-vis when the temperature of the priority part decreases, the heat transmitter will decrease the heating to the surplus heating part.

Description

technical field [0001] The invention relates to an electric heating method and device, in particular to a household electric water heater heating method and device. Background technique [0002] As a method of obtaining domestic hot water, electric water heaters are widely used in residential households. Compared with other types of water heaters, electric water heaters have the advantages of being clean, convenient, and not affected by the weather. [0003] The current heating method of electric water heaters mainly uses electric heating elements to directly heat water. Electric water heaters can be divided into preheating type and instant heating type, among which preheating type accounts for the vast majority. [0004] Preheating electric water heaters have significant disadvantages in the following aspects: [0005] 1. Before using hot water, it is necessary to heat the water for a long time in advance, which brings great inconvenience to the use, especially when hot ...

AI Technical Summary

Problems solved by technology

[0005] 1. Before using hot water, it is necessary to heat the water for a long time in advance, which brings great inconvenience to the use, especially when hot water is urgently needed

[0006] 2. When the hot water in the water heater is used up, it must wait for preheating again, and cannot continuously provide hot water for multiple people to take a bath

[0007] 3. The remaining hot water in the water heater needs intermittent heating and heat preservation, which increases energy consumption

[0008] 4. It has a large water tank, occupying indoor space and affecting the appearance

[0009] Although the instant electric water heater can solve the problem of no need for heating in advance, it has the disadvantage of inconvenient temperature adjustment, the water temperature fluctuates greatly with the change of water consumption, and the quality of the water temperature is low, so that it is difficult for this instant electric water heater to be widely used
